Beekeeping 101

Beekeeping is being enjoyed by a number of people who want a systematic way to study and improve the beekeeping industry. Beekeeping guide books are becoming very useful to the neophytes of this field.

Others may wonder why more and more people are beginning to get inclined to beekeeping. Aside from the fact that beekeepers are trying to learn more about the way of life of bees in order to improve their crops; some are merely interested to know the natural history of honeybees. People find satisfaction in gaining more and more knowledge on the field they are involved in. Thus a beekeeping guide is important to those who want to keep themselves busy as a bee in discovering more facts about this insect.

Brief History of Beekeeping

It is important to know a little background on how beekeeping started. Beekeeping can be traced back as far as the Bible times. There are even some verses in the Bible mentioning about honey. Honey is the produce of bees; it means that as early as that, people were already into beekeeping. Even the famous Aristotle did some study on the behavior of bees. His important learning says that bees do not hop from one flower to another to get honey; in fact bees remain constant in one flower until the honey is drained.

Bee Colony

It is a known fact that bee colonies have their Queen which lay the eggs; then drones are there to help in fertilizing the eggs of the Queen bee; and the rest are workers. The workers’ purpose is to ensure that they have sufficient supply of food. The bees know which category they belong so there is a division of labor among them.

Busy as a Worker Bee

Beekeeping guide information show that bee workers are the busiest among the categories of the bee colony. The focus of the bee workers are also subdivided into different categories. This will make their work easier and more systematized.

1. The builders are the ones assigned to build the comb of their colony. The comb builders use beeswax in creating their comb; beeswax comes from the body of the bee. The workers would secrete the beeswax from their body to make their comb.

2. The nurses, some workers would act as nurses to the eggs laid by the Queen bee. What they do is visit the cell where the eggs are laid. The nursing bees are the young bees for they cannot do other functions yet.

3. Food gatherers are the ones in-charge of looking for food. Bees pass the food from one worker to another to make work more precise. As the bees age, their ability to help in the transmission of food becomes better as well.

4. Guards and robbers are also the functions of bee workers. The guard bees would ensure the safety of the honeybee. They are usually stationed in the entrance of the beehive. The robbers on the other hand can be recognized by the guard bees through their behavior while flying and through their scent as well.

Bees are very interesting creatures; that is why more people are becoming bee-enthusiasts. Beekeeping guide is very important – to know and understand the behavior of this very hardworking insect.

Infectious Diarrhea

Clinical Presentation: Every year throughout the world more than 5 million people-most of them kids younger than 1 year-die of acute infectious looseness of the bowels. Although death is really a uncommon outcome of infectious diarrhea within the United States, morbidity is substantial.

It is estimated that you will find more than 200 million episodes each year, resulting in 1.8 million hospitalizations at a price of $6 billion per year. The morbidity and mortality attributable to diarrhea are largely due to loss of intravascular volume and electrolytes, with resultant cardiovascular failure. For example, adults with cholera can excrete a lot more than 1 L of fluid per hour.

Contrast this with the typical volume of fluid lost daily within the stools (150 mL), and it is clear why massive fluid losses connected with infectious diarrhea can lead to dehydration, cardiovascular collapse, and death. Gastrointestinal (GI) tract infections can present with primarily upper tract symptoms (nausea, vomiting, crampy epigastric pain), small intestine symptoms (profuse watery diarrhea), or large intestine signs or symptoms (tenesmus, fecal urgency, bloody looseness of the bowels).

Sources of infection consist of person-to-person   transmission  (fecal-oral spread of Shigella), water-borne  transmission  (Cryptosporidium), food-borne  transmission  (Salmonella or S aureus foods poisoning), and overgrowth following antibiotic administration (Clostridium difficile).

Etiology: A wide range of viruses, bacteria, fungi, and protozoa can infect the GI tract. However, in the majority of instances, symptoms are self-limited, and diagnostic evaluation isn’t performed. Individuals presenting to medical attention are biased toward the subset with more severe signs or symptoms (eg, high fevers or hypotension), immunocompromise (eg, HIV or neutropenia), or prolonged duration (eg, chronic diarrhea defined as lasting 14 days). An exception is large outbreaks of food-borne sickness, in which epidemiologic investigations may detect individuals with milder variants of illness.

Pathogenesis: A comprehensive approach to GI tract infections starts using the classic host-agent-environment interaction model. A quantity of host elements influence GI tract infections. Individuals at extremes of age and with comorbid conditions (eg, HIV infection) are at higher risk for symptomatic infection.

Medications that alter the GI microenvironment or destroy typical bacterial flora (eg, antacids or antibiotics) also predispose individuals to infection. Microbial agents responsible for GI sickness could be categorized according to kind of organism (bacterial, viral, protozoal), propensity to attach to various anatomic sites (stomach, little bowel, colon), and pathogenesis (enterotoxigenic, cytotoxigenic, enteroinvasive).

Environmental elements can be divided into three broad categories based on mode of  transmission : (1) water borne, (2) foods borne, and (three) individual to person. GI tract infections can involve the stomach, leading to nausea and vomiting, or affect the small and large bowel, with looseness of the bowels as the predominant symptom.

The term “gastroenteritis” classically denotes infection of the stomach and proximal little bowel. Organisms causing this disorder consist of Bacillus cereus, S aureus, and a quantity of viruses (rotavirus, norovirus). B cereus and S aureus produce a preformed neurotoxin that, even in the absence of viable bacteria, is capable of causing disease, and these toxins represent major leads to of foods poisoning.

Although the exact mechanisms are poorly understood, it’s thought that neurotoxins act locally, through stimulation of the sympathetic nervous system having a resultant improve in peristaltic activity, and centrally, through activation of emetic centers within the brain. The spectrum of diarrheal infections is typified by the diverse clinical manifestations and mechanisms via which E coli can trigger diarrhea.

Colonization from the human GI tract by E coli is universal, usually occurring within hours following birth. Nevertheless, when the host organism is exposed to pathogenic strains of E coli not normally present in the bowel flora, localized GI illness or even systemic sickness may occur.

You will find five major classes of diarrheogenic E coli: enterotoxigenic (ETEC), enteropathogenic (EPEC), enterohemorrhagic (EHEC), enteroaggregative (EAEC), and enteroinvasive (EIEC). Functions typical to all pathogenic E coli are evasion of host defenses, colonization of intestinal mucosa, and multiplication with host cell injury.

This organism, like all GI pathogens, should survive transit via the acidic gastric environment and be able to persist within the GI tract despite the mechanical force of peristalsis and competition for scarce nutrients from existing bacterial flora. Adherence can be nonspecific (at any part from the intestinal tract) or, a lot more commonly, particular, with attachment occurring at well-defined anatomic areas.

Once colonization and multiplication happen, the stage is set for host injury. Infectious diarrhea is clinically differentiated into secretory, inflammatory, and hemorrhagic kinds, with different pathophysiologic mechanisms accounting for these diverse presentations. Secretory (watery) diarrhea is caused by a quantity of bacteria (eg, Vibrio cholerae, ETEC, EAggEC), viruses (rotavirus, norovirus), and protozoa (Giardia, Cryptosporidium).

These organisms attach superficially to enterocytes in the lumen of the small bowel. Stool examination is notable for the absence of fecal leukocytes, even though in uncommon instances there’s occult blood in the stools. Some of these pathogens elaborate enterotoxins, proteins that improve intestinal cyclic adenosine monophosphate (cAMP) production, primary to net fluid secretion. The classic example is cholera.

The bacterium V cholerae creates cholera toxin, which leads to prolonged activation of epithelial adenylyl cyclase within the small bowel, primary to secretion of massive amounts of fluid and electrolytes into the intestinal lumen. Clinically, the patient presents with copious diarrhea (“rice-water stools”), progressing to dehydration and vascular collapse without having vigorous volume resuscitation.

ETEC, a common trigger of acute diarrheal sickness in young kids and the most typical trigger of looseness of the bowels in travelers returning to the United States from developing countries, creates two enterotoxins. The heat-labile toxin (LT) activates adenylyl cyclase in a manner analogous to cholera toxin, whereas the heat-stable toxin (ST) activates guanylyl cyclase activity.

Inflammatory diarrhea is really a result of bacterial invasion of the mucosal lumen, with resultant cell death. Patients with this syndrome are usually febrile, with complaints of crampy lower abdominal discomfort as nicely as diarrhea, which might contain visible mucous. The term dysentery is utilized when there are substantial numbers of fecal leukocytes and gross blood.

Pathogens connected with inflammatory looseness of the bowels consist of EIEC, Shigella, Salmonella, Campylobacter, and Entamoeba histolytica. Shigella, the prototypical trigger of bacillary dysentery, invades the enterocyte through formation of an endoplasmic vacuole, which is lysed intracellularly. Bacteria then proliferate within the cytoplasm and invade adjacent epithelial cells.

Production of a cytotoxin, the Shiga toxin, leads to local cell destruction and death. EIEC resembles Shigella both clinically and with respect towards the mechanism of invasion of the enterocyte wall; however, the specific cytotoxin associated with EIEC has not yet been identified. Hemorrhagic diarrhea, a variant of inflammatory diarrhea, is primarily triggered by EHEC.

Infection with E coli O157:H7 has been connected with a quantity of deaths from the hemolytic-uremic syndrome, with a number of well-publicized outbreaks related to contaminated foods. EHEC leads to a broad spectrum of clinical disease, with manifestations including (1) asymptomatic infection, (2) watery (nonbloody) looseness of the bowels, (three) hemorrhagic colitis (bloody, noninflammatory diarrhea), and (4) hemolytic-uremic syndrome (an acute illness, primarily of children, characterized by anemia and renal failure). EHEC doesn’t invade enterocytes; nevertheless, it does create two Shiga-like toxins (Stx1 and Stx2) that closely resemble the Shiga toxin in structure and function. After binding of EHEC towards the cell surface receptor, the A subunit of the Shiga toxin catalyzes the destructive cleavage of ribosomal RNA and halts protein synthesis, leading to cell death.

Clinical Manifestations: Clinical manifestations of GI infections vary depending on the on website of involvement For instance, in staphylococcal foods poisoning, symptoms develop several hours after ingestion of foods contaminated with neurotoxin-producing S aureus. The symptoms of staphylococcal food poisoning are profuse vomiting, nausea, and abdominal cramps.

Diarrhea is variably present with agents leading to gastroenteritis. Profuse watery (noninflammatory, nonbloody) diarrhea is connected with bacteria that have infected the small intestine and elaborated an enterotoxin (eg, Clostridium perfringens, V cholerae). In contrast, colitis-like symptoms (lower abdominal pain, tenesmus, fecal urgency) and an inflammatory or bloody diarrhea occur with bacteria that more generally infect the large intestine.

The incubation period is usually longer (> 3 days) for bacteria that localize towards the large intestine, and colonic mucosal invasion can occur, causing fever, bacteremia, and systemic symptoms.

Wide Area Network (WAN)

Types and Characteristics of WANs

What is a WAN?

There are two prevailing definitions of a Wide Area Network (WAN). The book definition of a WAN is a network that spans large geographical locations, usually to interconnect multiple Local Area Networks (LANs). The practical definition of a WAN is a network that traverses a public network or commercial carrier, using one of several WAN technologies

What are its Main Components?

The main components for a WAN are routers, switches and modems. These components are described below in the hardware section.

CPE – Devices on the subscriber premises are called customer premises equipment (CPE).

The subscriber owns the CPE or leases the CPE from the service provider. A copper or fiber cable connects the CPE to the service provider’s nearest exchange or central office. This cabling is often called the local loop, or “last-mile”.

DTE/DCE – Devices that put data on the local loop are called data circuit-terminating equipment, or data communications equipment (DCE). The customer devices that pass the data to the DCE are called data terminal equipment (DTE). The DCE primarily provides an interface for the DTE into the communication link on the WAN cloud.

Hardware

In a WAN you will need various types of hardware components for it to function. The typical items of hardware that you will need in a WAN are:

Router – An electronic device that connects a local area network (LAN) to a wide area network (WAN) and handles the task of routing messages between the two networks. Operates at layer 3, and makes decisions using IP addresses.

Switch – A switch is a network device that selects a path or circuit for sending a unit of data to its next destination. Operates at layer 2, and uses MAC addresses to send data to correct destination.

Modem – Short for modulator/demodulator, a modem enables a computer to communicate with other computers over telephone lines. Operates at layer 1, where signals are converted from digital to analogue and vice versa for transmission and receiving.

Wan Standards

WANs operate within the OSI model using layer 1 and layer 2 levels. The data link layer and the physical layer. The physical layer protocols describe how to provide electrical, mechanical and functional connections to the services provided by the ISP. The data link layer defines how data is encapsulated for transmission to remote sites.

Encapsulation

Encapsulation is the wrapping of data in a particular protocol header. Remember that WANs operate at the physical layer and the data link layer of the osi model and that higher layer protocols such as IP are encapsulated when sent across the WAN link. Serial interfaces support a wide range of WAN encapsulation types, which must be manually specified. These types include SDLC, PPP, Frame delay etc. Regardless of WAN encapsulation used it must be identical on both sides of the point to point link.

Packet and Circuit Switching

Circuit switching and packet switching are both used in high-capacity networks.

The majority of switched networks today get data across the network

through packet switching.

Circuit-switching is more reliable than packet-switching. Circuit switching is old and expensive, packet switching is more modern.

General Routing Issues

What is a Routing Protocol?

A routing protocol is a protocol that specifies how routers communicate and exchange information on a network. Each router has prior knowledge of its immediate neighbours and knows the structure of the network topology. The routers know this because the routing protocol shares this information.

Protocol

RIP (Routing Information Protocol) was one of the most commonly uses protocols on internal networks. Routers use RIP to dynamically adapt changes to the network connections and communicate information about which networks routers can reach and the distance between them. RIP is sometimes said to stand for Rest in Pieces in reference to the reputation that RIP has for breaking unexpectedly and rendering a network unable to function.

Routing Algorithms

Distance Vector

This type of routing protocol requires that each router simply inform its neighbours of its routing table. The distance vector protocol is also known as the bellman-ford algorithm.

Link State

This type of routing protocol requires that each router maintain a partial map of the network. The link state algorithm is also know as Dijkstra’s algorithm.

IGRP

IGRP is a type of distance vector routing protocol invented by cisco used to exchange routing data in a autonomous system. Distance vector protocols measure distances and compare routes. Routers that use distance vector must send all or a portion of their routing table in a routing update message at regular intervals to each neighbour router.

Addressing and Routing

What does routing mean?

Routing is the process of deciding how to move packets from one network to another.

The directions also known as routes can be learned by a router using a routing protocol then the information is passed from router to router along the route of the destination.

IP Address’s

Every machine connected to the internet is assigned an IP address. An example of an IP address would be 192.168.0.1. IP addresses are displayed in decimal format to make it easier for humans to understand but computers communicate in binary form. The four numbers that separate an IP address are called Octets. Each position consists of eight bits. When added to together you get 32 bit address. The purpose of each octet in an IP address is to create classes of IP addresses that can be assigned within a network. There are three main classes that we deal with Class A, B and C. The octets of an IP address are split into two parts Network and Host. In a class A address the first octet is the network portion, this determines which network the computer belongs to, the last octets of the address are the hosts that belong to the network.

Sub netting

Sub netting allows you to create multiple networks within a class A, B or C address. The subnet address is the address used by your LAN. In a Class C network address you would have a subnet mask of 255.255.255.0. A subnet mask identifies which portion is network and which is host. For example 192.168.6.15 the first octet three octets are the Network address and the last octet being the host(Workstation). It is important to subnet a network because gateways need to forward packets to other LANS. By giving each NIC on the gateway an IP address and a Subnet mask it allows the gateways to route packets from LAN to LAN. Once the packet arrives at its destination, the gateway then uses the bits of the subnet portion of the IP address to decide which LAN to send the packets.

Circuit Switched Leased Lines

A circuit switched network is one that establishes a dedicated circuit (or channel) between nodes and terminals before the users may communicate. Here are some terminologies associated with a Circuit switched network.

Frame relay is a telecommunication service designed for cost-efficient data transmission between local area networks (LANs)

Basic rate interference is a service used by small business for internet connectivity. An ISDN BRI provides two 64 Kbps digital channels to the user.

Primary rate interface (PRI) is a telecommunications standard for carrying voice and data transmissions between two locations

All data and voice channels are ISDN and operate at 64kbit/s

Packet Switching

http://www.raduniversity.com/networks/2004/PacketSwitching/main.htm – _Toc80455261

Packet switching refers to protocols in which messages are broken up into small packets before they are sent. Each packet is then transmitted over the Internet. At the destination the packets are reassembled into the original message. Packet switching main difference from Circuit Switching is that that the communication lines are not dedicated to passing messages from the source to the destination. In Packet Switching, different messages can use the same network resources within the same time period.

http://en.wikipedia.org/wiki/Asynchronous_Transfer_Mode

Asynchronous Transfer Mode (ATM) is a cell relay, packet switching network and protocolwhich encodes data into small fixed-sized cells.

ISDN is used to carry voice, data, video and images across a telephone network. ISDN stands for integrated services Digital Network. Isdn also provides users with a 128kbps bandwidth. This is done through frame relay. Frame relay complements and provides a service between ISDN, which offers bandwidth at 128 Kbps and Asynchronous Transfer Mode which operates in somewhat similar fashion to frame relay but at speeds from 155.520 Mbps or 622.080 Mbps. Frame relay is based on the older X.25 packet switching technology and is used to transmit analogue signals such as telephone conversations.

PSDN stands for packet switched data network and is a data communication network. Packet switched networks do not establish a physical communication signal like the public telephone does (circuit switched network) Packets are sent on a fixed length basis and assigned with a source and a destination address. The packets then rely on the routers to read the address and route the packets through the network.

Mobile and Broadband Services

Digital Subscriber line(DSL) is mainly used to bring high bandwidth connections to homes and small business’s over a copper wire telephone line. This is can only be achieved if you stay within the range of the telephone exchange. DSL offers download rates of up to 6mbps allowing continuous transmission of video, audio and 3D effects. DSL is set to replace ISDN and compete with the cable modem in providing multimedia to homes. DSL works by connecting your telephone line to the telephone office over copper wires that are twisted together.

Asymmetric Digital Subscribers Line is most commonly used for home users. It provides a high download speed but a lower upload speed. Using ADSL, up to 6.1 megabits per second of data can be sent downstream and up to 640 Kbps upstream.

http://en.wikipedia.org/wiki/Symmetric_Digital_Subscriber_Line

Symmetric Digital Subscriber Line is a digital subcriber line which runs over one pair of copper wires. The main difference between ADSL and SDSL is the difference in upload and download speeds. SDSL allows the same upstream data rate and downstream data rate as ADSL upstream can be very slow.

[http://searchnetworking.techtarget.com/sDefinition/0],,sid7_gci558545,00.html

HDSL High bit-rate Digital Subscriber Line, one of the earliest forms of DSL, is used for wideband digital transmission within a corporate site and between the telephone company and a customer. The main characteristic of HDSL is that provides equal bandwidth in both directions.

IDSL is a system in which data is transmitted at 128 Kbps on a regular copper telephone line from a user to a destination using digital transmission.

The Local Loop enables operators to connect directly to the consumer via copper local loops and then add their own equipment to offer broadband and other services. This process involves operators accessing local exchange buildings to connect to a network of copper lines which connect them to homes and businesses. BT is an Example of a Local Exchange. The local loop connecting the telephone exchange to most subscribers is capable of carrying frequencies well beyond the 3.4 kHz upper limit.

Benefits of using DSL

DSL can provide virtually instantaneous transmission of voice, data and video over ordinary copper phone lines. A DSL connection can eliminate delays when waiting to download information and graphics from the Internet. It provides users with a cost effective high speed Internet connection. Another benefit is that a DSL connection is always on-line (like a LAN connection) with no waiting time for dialling or connecting.

There are now more than 10 million broadband connections in the UK. By December 2005 there were 9.792 million broadband connections in the UK and the average broadband take up rate during the three months to December was more than 70,000 per week.

Japan’s Big Three’s Models Named Best Deals

Car buyers are always in the lookout for the car offering the best value for their money. Different firms have been guiding prospective car buyers on how to choose the vehicle the suits their needs best. From performance to fuel economy to safety, all bases should be covered in choosing a vehicle.

IntelliChoice, one of the leading sources of pertinent information to car buyers, recently announced their “Best Deals” list. The list contains what the online outfit thinks is the best vehicle in different classes. For the month of April, IntelliChoice announced their “Best Deals” and this has been done coinciding with the ongoing New York International Auto Show (NYIAS) in the Big Apple.

This month’s list includes several models from Japan’s three biggest car manufacturers. These vehicles are seen as the measuring stick for future production vehicles unveiled and showcased at the New York Auto Show. James Bell, the publisher of IntelliChoice.com, has this to say with regards to the list and the vehicles showcased at the event: “Even more than recent auto shows, the New York show offered a look at some very compelling future competition to many of the mainstays on our monthly ‘Best Deals’ list.”

The Honda Civic hybrid is rated as the best deal for the Compact Car over $16,000 class by IntelliChoice.com. For the Compact Car under $16,000 class, the best deal is touted to be the Honda Civic DX with an automatic transmission.

Aside from these two models, another Honda produced vehicle was named as a best deal in its class – the Honda Civic Si. The said model is named as the best deal in the Base Sport Car class. The Honda Odyssey is once again named as the best deal for the Minivan class. The Honda Odyssey has been dominating that class in recent history but will face strong competition in the form of the Ford Flex recently unveiled at the New York International Auto Show.

A Nissan model is also named as one of the best deals for the month of April. The Nissan Frontier King Cab XE 2WD with a manual transmission is named as the best deal for the Compact Pickup Truck 2WD class. The King Cab is the first crew cab body style compact pickup truck in North America and since its inception in the U.S. auto market has been popular among car buyers. With its trademark dependability, the Nissan Frontier is not a surprise choice as the best deal for its class. Its high performance construction and components such as the Nissan spark plug wires are one of the reasons why the Frontier sits at the top of its class.

Toyota, the surging Japanese car manufacturer, also landed several of its models at the “Best Deals” list. The popular Toyota Prius is named as the best deal for the Midsize Car under $21,000 while the Prius Touring is named as the best deal for the Midsize Car over $21,000 class.

For the Large Car class, IntelliChoice picked the Toyota Avalon Touring as the best deal for consumers. The Toyota Highlander Hybrid with a third row seating and 2WD configuration is named as the best deal for the Midsize Crossover class. The Toyota Matrix Standard with manual transmission is also named as the best deal for the Small Wagon class.

For the Compact Pickup Truck 4WD class, IntelliChoice picked the Toyota Tacoma Regular Cab 4WD as the best deal. The Toyota Tundra Regular Cab V6 2WD Short Bed is named as the best deal for the Full-Size Pickup Truck 2WD 1/2 Ton class.

Ring Worm

Ringworm, also termed tinea corporis, is an infectious skin disease caused by mold-like fungi called Dermatophytes. This disease usually transmits through direct contact with ringworm-infected animals or with humans by sharing combs, clothing or by touching infected areas. Despite its name, there are no worms involved at any phase of the ringworm process. It used to be believed that a worm caused or was a symptom of ringworm, but now people know better. However, the name stuck.

The common symptoms for ringworms are itching, burning, dryness, or circular flaky rashes on the skin. Though, in the case of animals, the primary symptom is temporary hair loss in affected areas, itching or scratchiness in a specific body part.

A primary cause of ringworm is direct contact with infected animals or humans.

Ringworm is common among pets especially dogs and cats, who carry this disease from contaminated soil, kennels or from rodent burrows.

Ringworm thrives in moist conditions and commonly affects the scalp, toes, feet, thighs and genital area. Prevention requires that these areas be kept dry and clean to avoid infection, and pets should have regular veterinary checkups.

Ringworm is easily curable and there are several treatments available. At the first sign, see your doctor who can prescribe mediation to treat and cure ringworm within 2-3 weeks. Ringworm may not show up right away upon the time of contraction. In other words, it can exist as a contagious disease for a time before it can be detected. So do not blame others if their ringworm shows up before yours; you may have been the carrier in the first place!

The True Difference Between Motorcycle Oil and Automotive Oil

To some people, changing the oil in your car is just like changing the oil in your motorcycle. Just drain out the old oil, install a new oil filter, and pour in the desired amount of new oil and your done. So when it comes time to change your motorcycle oil, why can’t you use the same oil that you use in your car? Motorcycle oil and automotive oil look and feel the same so how could there be a difference between the two?

Automotive oil looks pretty enticing at $3 a quart but any experienced motorcycle rider knows that using automotive oil in motorcycles causes serious damage. In automotive vehicles, the engine is always separate from the clutch and   transmission  so they have separate oils for each. In automotive engine oil, there is more of what is called “friction modifiers” to help lessen the amount of friction on engine components and improve fuel economy. Of course, improving fuel economy has always been the main goal of the automotive industry making friction modifiers a necessity for all automotive oils.

These friction modifiers that are added to automotive oils are what cause serious damages when used in motorcycles. The friction modifiers clog the clutch plates in a motorcycle’s  transmission  causing serious clutch slippage and disabling the motorcycle. You see, for motorcycles to be as compact as they are, they have to combine their engine and  transmission  into one casing. This means that everything is lubricated by only one type of oil including the valves, piston,  transmission , and clutch.

Motorcycles require very little and/or no friction modifiers to help improve clutch friction and to prevent clutch slippage. But to make up for this lack of friction modifiers, motorcycle oils use higher levels of anti-wear additives such as ZDDP, also known as phosphorous, to limit engine friction and wear. Since motorcycle oil has extra anti-wear additives and is lubricating so much more than automotive oil, you can expect to pay anywhere from $9 to $15 a quart.

To some people, both oils look and feel the same but now you know the facts of each. So the next time that you decide to change your motorcycle oil, go straight to your local motorcycle dealer and buy only high quality motorcycle oil designed specifically for the type of motorcycle you own. Make sure that you change your oil periodically to keep it fresh and clean to ensure a long life for your engine,  transmission , and clutch.

Warts – Types and Treatment

There are many different types of warts, all of which have one thing in common… they are embarrassing, unpleasant, cosmetically unattractive, unwanted, annoying and sometimes painful protrusions that appear on the skin almost anywhere. They have always been considered ugly and in folklore over the years… witches have usually modelled a whole host of various ‘warty’ protrusions on various parts of their anatomy. In fact the larger the wart… the more evil the witch! The princess never had warts… the wicked stepmother had them though! The ‘goodies’ never sported a fashionable wart but the baddies were regularly seen displaying one or more particularly heinous ones.

What are warts and why do we get them?

They are completely benign epidermal tumors or growths on the skin and most of them are highly contagious. They originate from the human papilloma virus (HPV) which causes the infection and more than 100 HPV subtypes are known.

Warts are particularly common in childhood and are spread by direct contact or by touching itching and spreading through touch. If a wart is scratched, the viral particles may be spread to another area of skin. It can take as long as twelve months for the wart to first appear and they can just as easily spontaneously disappear temporarily or even permanently. The majority of them have a hard surface and a tiny black dot in the middle or each warty mark can often be seen. This is a capillary blood vessel seen through the skin. Warts can develop individually or in clusters and can spontaneously disappear. Hygiene must be of the highest importance to avoid cross infection and if not treated they may spread.

In children, even without treatment, some warts disappear within 6 months and up to 90% are gone in 2 years. They are more persistent than this in adults but they can sometimes disappear of their own accord.

Warts are particularly numerous and troublesome in patients that are immuno-suppressed.

There are many types of warts:

1. Common warts arise most often on the backs of fingers or toes, palms of hands and on the knees.

2. Plantar warts (verrucas) are seen on the foot – mainly on the sole of the foot.

3. Mosaic warts are also seen on the sole of the foot and appear in clusters over an area often proliferating to several centimeters in diameter. Many little dots from capillaries underneath the surface of the skin can be seen throughout mosaic warts.

4. Plane, or flat, warts are often seen on the face or limbs and under the arms and can be very numerous.

5. Periungual warts grow at the sides or under the nails and can distort nail growth if left. Treatment can be difficult because of the sensitivity of the area and the risk of damaging the nail bed.

6. Filiform warts are on a long stalk and these can appear quite often on the face where they are a most upsetting and cosmetically unattractive addition. They often have a multi faceted top like finger like projections which are very dry and crusty.

7. Oral warts can affect the lips and even inside the cheeks. They include Squamous Cell Papillomas (not to be confused with Squamous Cell Carcinomas), are small benign (non-cancerous) growth that begin in squamous cells (thin, flat cells) that are found in the tissue that forms the surface of the skin (epidermis), the passages of the respiratory and digestive tract and in the lining of hollow organs of the body.

8. Genital warts are very common. There are at least 100 different types of HPV and at least 40 can infect the genital area they are often transmitted sexually and predispose to cervical, penile and vulval cancers.

Treatment Options:

Warts are not a serious health condition and many people will not bother to treat them as often the treatment is uncomfortable and requires considerable effort. To get rid of them, the body’s own immune system has to be stimulated to attack the wart virus. Persistence with the treatment and patience is essential!

There are several options of treatment, some more successful than others.

Electrolysis

Electrolysis has been around for over 130 years for hair removal but is fairly new to wart treatment but is proving high successful and illustrating excellent results. It is a very precise form of treatment not unlike Electrosurgery (curettage and cautery) but is gentler and less invasive. Treatment techniques depend upon the type of wart but with a common wart the tiny electrolysis needle (about the size of a eyelash) is used to cauterise the surface of the skin over the affected area. This is then inserted into the centre of the wart where a high frequency, radio frequency current is expelled. Following treatment the surface of the wart will scab over, which will, after a week or so, slough away leaving perfect skin behind. More than one treatment may be required with verrucas in particular being very resilient and definitely needing more than one treatment.

Other methods of treatment include:

Occlusion. By covering the wart 24 hours of the day may result in it clearing. Duct tape is often used.

Chemical treatment. Chemical treatment includes wart paints containing salicylic acid which remove the dead surface skin cells. Perseverance is essential as it can take 12 weeks to go or more likely to reduce in size.

Cryotherapy. The wart is repeatedly frozen with liquid nitrogen resulting in blistering, swelling and sometimes permanent white scarring following treatment.

Electrosurgery (curettage & cautery) is used for particularly large and annoying warts. Under local anaesthetic, the growth is pared away and the base burned by diathermy or cautery. The wound heals in about two weeks.

Other treatments. There are numerous treatments for warts and none offer a guarantee of cure. They include: Topical creams, oral medication, vaporisation, pulse dye laser destruction of feeding blood vessels and even duck tape and banana skin are home care options.

Interesting Facts about Ringworm

In spite of its popular name, the actual cause of ringworm is infection with fungal organisms. These infectious fungal organisms are called dermatophytes and the medical term for ringworm is dermatophytosis. Sometimes ringworm is also known as tinea. The fungal infectious organisms responsible for causing ringworm are widespread in nature and they commonly populate the soil. The only effective means of preventing the occurrence of ringworm is to maintain a good hygiene. Ringworm is very contagious and it can easily be acquired through direct contact with contaminated people, animals or objects. Regularly wash your hands after entering in contact with stray animals, as many of them are carriers of the fungi responsible for causing ringworms in humans.

Arthrospores are the main cause of ringworm in humans. Although there are lots of animals contaminated with arthrospores, they usually don’t show any signs of the disease. For some reason, most animals appear to be immune to this form of fungal infection. Microsporum canis is a type of fungi that commonly infects cats. This type of fungus can be easily transmitted to other animals and to humans. It is strongly recommended to avoid physical contact with animals that show signs of disease in order to prevent contamination with infectious fungal elements. Also, if you own a dog or a cat, ensure that your pet is not contaminated with dermatophytes by paying regular visits to a veterinary.

Ringworm can affect virtually any region of the body. Hands and feet are very exposed to fungal infection and dermatophytes often infect these body parts. Although it commonly affects skin, ringworm can also affect nails and scalp. Ringworm involves inflammation, rash and swelling of the skin, scalp, soft tissue and nails. Rash is usually the first sign that indicates the presence of fungal infections. Skin lesions may also appear in later stages of the disease. If the infection spreads through the deeper layers of the skin it can cause pustules and painful nodules. A hardened crust often forms on the surface of the affected skin. Common symptoms of ringworm are persistent itching, soreness and irritation.

Ringworm of the scalp appears in the form of pustules or pus-filled reddish bumps. Foot ringworm usually affects the skin regions between the toes. Foot ringworm appears in the form of cracked, hardened skin. The affected skin also tends to exfoliate, causing itching and soreness. Ringworm of the nails is manifested by thickening and discoloration of the nails.

It is very important to see a dermatologist if you have the symptoms of ringworm. Although it may resemble a simple rash or irritation, ringworm can cause serious complications if it is not appropriately treated. The treatment for ringworm can be prescribed in the form of oral tablets or creams and ointments for external use. The medications used in the treatment for ringworm contain antifungal material and they are usually very effective in overcoming the infection. With appropriate medical treatment, ringworm can be completely cured within a week.

Honda Motor Scooter Guide

Driving a car, truck or SUV can be pricey when you factor in the cost of rising gas prices. If you are a single motorist or only use your vehicle for commuting, an alternative to consider is a Honda motor scooter. There are currently six different models to choose from and of the various designs available, one is sure to meet all of your needs. Running errands around town, seating for two, storage space, long-distance riding and engine performance are just some options to consider when thinking about the kind of scooter you would like to be riding.

The Metropolitan model from Honda offers single seating for the modern rider. This scooter is perfect for the driver looking for sharp European design while being fuel efficient. Automatic   transmission  is also a perk for those who are new to riding scooters as shifting gears may seem intimidating. A 49cc engine gives a top speed of 40 miles per hour which is plenty fast for local around-town driving or commutes that do not involve travel on highways.

Are you looking for a two-seat scooter with generous storage space and a little more engine zip than the Metropolitan? A Honda motor scooter that could be for you is the Honda Elite model. Reach speeds up to 50 miles per hour with its 108cc engine while riding comfortably with a second person seated behind you. And you do not need to worry about taking your helmet with you after reaching your destination with this model’s under seat storage feature.

Honda’s Ruckus model offers a rugged exterior as opposed to the smooth lines of the Metropolitan and Elite scooters. Automatic  transmission , a liquid-cooled engine and electric start are all features of this Honda motor scooter. Oversized tires allow for handling a bit rougher terrain while still enjoying the fuel efficiency that driving a scooter provides.

The PCX scooter offered by Honda engages a 125cc engine that can travel up to 60 miles per hour. A trunk allowing for a full size helmet and an accessory rack ensures you will have the space needed to accommodate all of the items you may be traveling with. Some highway travel is permitted with this motor scooter which may be a great option for commuters.

A sleek model that gets you from point A to point B faster and with room for two is Honda’s SH150i. This fuel-injected scooter features a 153cc engine and a Combined Braking System. A top speed of 65 miles per hour with two riders makes this scooter an ideal option for those looking for local and highway travel.

Finally, the Silver Wing ABS is the ultimate luxury scooter from the Honda line. An ample windscreen and seating for two offers comfort to all riders while the 582cc engine delivers power for those longer rides. The anti-lock braking system and automatic  transmission  offered with this Honda motor scooter model is sure to provide fast and fun transport for the motorist looking for ultimate comfort.

Online Education – Do You Want To Return To School?

In our rapidly changing global world, millions of students are currently taking college-level online (distance education) classes. Private and public universities in the United States and abroad are offering Certificate, Baccalaureate, Masters and Doctoral degree programs over the Internet to adult learners. From Ivy League to Community Colleges, an increasing number of students can log on to their classes from home, work or while commuting by bus and train. Adult learners frequently juggle a myriad of responsibilities including raising children, career, and care giving for senior parents. Formerly, a university of interest may have been out of reach geographically. Presently, an employee located in the United States can register for classes taught half way around the world. Non-traditional venues outside of the more traditional classroom offer viable opportunities for continuing one’s education.

Adult learners make up the largest demographic of post-secondary institutions in the United States. For this student group, the benefits of online academic programs are:

o To update current skill sets

o To learn new skill sets

o To earn an undergraduate or graduate level degree

o The fulfillment of academic requirements necessary for a current job or promotion

o To change careers

o The satisfaction of certification or licensure requirements

o Personal and spiritual growth and development

Not for the faint of heart, success in distance education academic programs requires high levels of stamina, discipline, and motivation. A good candidate must be computer literate, possess the ability to read massive amounts of material in short-time frames, have good writing and communication skills, hold high expectations for good grades, enjoy applying critical thinking and commit a minimum of 15 hours per week per course (be prepared to allocate more, if necessary).

The Internet and the World Wide Web provide the critical technology platform for distance education. University technological and operational infrastructures (including hardware, software and transmission) provide the additional cornerstones to the technology platform needed to execute distance education programs. The delivery of academic content may be accomplished in several formats. The more traditional venues are correspondence courses, videos, audio-cassettes, CD-ROMS, and broadcasts via television and radio. Modern formats include synchronous and/or asynchronous education content distribution channels. Synchronous delivery refers to real-time interaction between instructor and student i.e., two-way video-conferences, whiteboards, chat rooms, telephone software (ex. Skype), and mobile technology devices. Asynchronous interaction does not involve real time communication. Instead, interaction between instructor and student is accomplished through the use of e-mail, DVDs, and the traditional education delivery formats.

As a student, you will need a desktop or laptop computer, an Internet Service provider, a cell phone, software (i.e., word processor, financial spreadsheet, calendar and Power Point), a backup storage disk drive (nothing can make your heart drop faster than losing a body of work that you’ve diligently developed), a headset with microphone for virtual team discussions and the traditional school supplies. Optional technology may include memory upgrades, scanners, digital scanners, and fax machines.

Ten Tips For The Successful Online Student:

o Have a credit card or debit card ready for downloading e-books and other required course reading materials.

o Maintain a list of more than one bookstore in the event that a required textbook is sold out. It’s always a good idea to obtain a list of the required textbooks midway through the term and order in advance for the following term.

o Do not be shy about asking for help if needed. I cannot stress enough the importance of communicating openly with your professor or instructor about course material that you may not understand. Online academic programs tend to move rapidly and course content that you do not understand will most likely cause problems down the road resulting in frustration and possibly, lower grades.

o Seek out a tutor. If there are areas that you know need strengthening, even before the class begins, have a tutor on stand-by. Also, the telephone number of a computer specialist should be in your rolodex.

o Time management will be critical. Keep a planner. Read your syllabus as soon as it becomes available and plan accordingly.

o Uphold your responsibilities as a virtual team member. Your contributions will directly impact the team grade.

o Exercise. Long hours at the computer can cause strain on the neck, shoulder, arm and back muscles, not to mention the hands. Remember to periodically stretch and tone.

o Eat a healthy diet. Keep good healthy recipes handy. Hydrate. Avoid heavy snacking on calorie-laden food and instead eat lots of fruit and vegetables. Avoid white flour and choose high fiber grains.

o See your doctor. A healthy body feeds a healthy mind.

o Stay in contact with your Academic Advisor to be sure that you are satisfying the requirements needed to complete your degree.

In the Fall term of 2006, 3.5 million students representing 20% of all U.S. higher education students, took at least one online course (2007. The Sloan Consortium). It is projected that distance education will continue to grow in popularity domestically and internationally. The most commonly offered online academic programs are Business, Computer Science and Engineering, Education, Engineering, Library Science, Nursing, and Public Health. Whether you select a community college, public institution, private institution or Ivy League university, enjoy the learning experience.
