Gigabyte H81M-S2PV Mother board works with 4-pin ATX power connector

Yesterday I installed a new I3-4150 processor and Gigabyte H81M-S2PV in my old casing with a 450W 4-pin ATX power supply. This board requires and 8-pin ATX power supply. Actually I did not expect it to work. To my surprise it started working. I installed windows 8.1 and no system instability so far.
It works great.
For your information I have attached a picture below.

Effective use of EV mode in Toyota Aqua and Toyota Prius

 Effective use of EV mode in Toyota Aqua and Toyota Prius 

If you are a driver of a Toyota Aqua or a Prius, especially you are new to the vehicle you may be bit curious about this EV mode button. You must have try to engage the EV mode but it may not have worked giving you an error beep instead. So lets talk about this mysterious EV mode. EV mode forces the vehicle to run using the battery. So the vehicle will run in the EV mode until the battery is drained to 20%. Then the vehicle will automatically switch to the normal driving mode. 

Following are the prerequisite for the EV mode to work in Toyota Aqua/Prius 

Pushing the EV-Mode button cycles into and out of EV-Mode, if allowed. 
  1. On cold days, heat and defrost will both prevent EV mode if the engine is not warm enough (usually > 150F) 
  2. The battery voltage must remain above 180v. 
  3. The Charge Current Limit must remain above 50A. 
  4. The battery must be above 50% SOC to engage EV mode. 
  5. The battery must remain below 80% SOC . 
  6. The traction battery must remain below 120°F The traction battery must be below 113°F to engage EV mode. 
  7. The gas engine (ICE) must be above 32°F (0°C) to engage EV mode. 
  8. The speed must remain below 60 km/h 
  9. The accelerator pedal must not be depressed more than about half to 3/4 of the way down 

Let’s say you have fulfilled all the prerequisites. But if you engage the EV mode unintelligently your battery will be drained after a short distance and you will have to continue you journey using ICE till your battery is charged. So this is not beneficial at all in terms of fuel efficiency.

 But there are certain ways you can use the EV mode to drive efficiently. 

Let’s say you are driving on a 10km down slop with intermittent small up slopes. This is an ideal rout to use the EV mode. When you drive in the down slope all the potential energy will be stored in the battery and it will be used to climb small up slopes. 

Now you are driving on the flat road and there is a small hill. But after that the road is flat. You can again use EV mode to climb the hill. And after a long journey you can use EV mode to park your vehicle.

Using Wget linux command for mediafire downloads

 Using Wget linux command to download form  mediafire

I wanted to download several files from mediafire. But those files were large and my internet connection is slow. So i thought of downloading those to my network associated storage. My network associated storage is NS-320U. A chinese one which uses a linux core. So access it I used PUTTY shell program.

Please follow the following steps and you will find it very easy to do this in the command line.

But first you have to open the mediafire URL in a computer browser and start the download. For this I prefer Firefox. Then pause the download and copy the Actual download link by right clicking the download status bar. 

If you simply copy past the mediafire link it will only download the html file. IT WII NOT WORK.

Now open the command line program of your choice. I am using PUTTY SSH you can use Wget function in the LINUX to download the file.
the command should be something like this.
wget -P /usb/sda1/
( should be replaced with previously copied link)
if you want to continue downloading the file after you close the command line window you can have the following modification to your command.

nohup wget -P /usb/sda1/

Driving Toyota Aqua fuel Efficiently

Using Toyota Aqua fuel Efficiently
Toyota Prius C

You may be wondering about the ways to improve fuel efficiency of your new Toyota Aqua hybrid vehicle. May be an aftermarket gadget?
Well when it comes to fuel efficiency most important determinant is the way you drive. If your driving habits are smooth your vehicle will register someway around 25km/l to 30km/l.
When it comes to that I can give you some tips
  1. Keep your acceleration low; don’t step on the gas pedal unnecessarily
  2. If you want to reduce the speed of your vehicle apply breaks beforehand and reduce the speed slowly. Avoid sudden breaking. Smooth application of breaks will produce more regenerative energy.
  3. Read the road ahead
  4.  When you have accelerated your vehicle to the required speed suddenly release the accelerator. This will switch off the ICE (Internal combustion engine) and switch the vehicle to the battery mode. You will be able to see EV in the smart meter. Now accelerate slowly to maintain the speed.
Those tips are for the driving habits folks. Now let’s look at some other aspects.
Do not switch on AC for short trips. Because the AC will consume more energy+fuel when you switch it on at the beginning after some time it will come down. But if you are traveling only 2km – 4km distances switching on AC will reduce your fuel efficiency drastically.
EV mode can be used to improve fuel efficiency. We’ll talk about it in a future post.

CPK Enzymes

There are different isoforms of CPK enzyme. These isoforms are known as CPK enzymes. Those are CPK-BB (Which is present in the brain cells) CPK-MM (Present in the skeletal muscles) CPK-MB (Present in the myocardial cells) Isolation of these different CPK enzymes ( isoforms) provide a significant therapeutic value. For an example in a myocardial infarction the blood level of CPK-MB is elevated. In an injury to skeletal muscles the blood level of CPK-MM is elevated. So the plasma level of CPK enzymes can be used to diagnose various diseases. This provides a great therapeutic tool for the doctors to uphold the health of the patient.
Elevation of CK is an indication of damage to muscle. It is therefore indicative of injury, rhabdomyolysis, myocardial infarction, muscular dystrophy, myositis, myocarditis, malignant hyperthermia and neuroleptic malignant syndrome. It is also seen in McLeod syndrome and hypothyroidism. The use of statin medications, which are commonly used to decrease serum cholesterol levels, may be associated with elevation of the CPK level in about 1% of the patients taking these medications, and with actual muscle damage in a much smaller proportion.

How does paracetamol / acetaminophen relieve pain?

How does paracetamol / acetaminophen relieve pain?

Free nerve endings are responsible for the perception of pain. There are some chemical mediators of pain like bradykinin which stimulate free nerve endings and causes pain sensation. Drugs like paracetamol / acetaminophen are called NSAID s or Non Steroid Anti Inflammatory Drugs. These drugs inhibit a class of enzymes called COX ( cycloxygenase ) There are three types of cycloxygnase. COX-1, COX-2 and COX-3. COX is responsible for the synthesis of prostaglandins in various parts of the body. Prostatglandin sensitize free nerve endings to chemical mediators of pain So when the prostaglandin production decreased pain sensation decreases. Paracetamol also known to be a selective inhibitor of COX-3.

How does Codeine cause constipation

Codeine, a closely related substance to morphine (so codeine is also an opioid) converted in the body to morphine. Codeine is readily absorbed by mouth and it does not have the dependent effect of morphine. But since it is converted in the body to morphine it can cause various gastro-intestinal symptoms. So codeine increases the tone and reduces the motility of many parts of the gastro intestinal tract. This can delay the gastric emptying and considerably reduces the absorption of the other drugs. It can also increase the pressure in the biliary system since it increases the contraction of the gallbladder and increase the tone of the biliary sphincter. So codeine should be avoided in patients with biliary colic caused by gallstones. This action on gastro intestinal smooth muscles can cause severe constipation in some patients and it can be very troublesome to them.

Importance of plants

Importance of plants

Plants are important for human life in many ways. Without plants animal life on the planet earth would be almost impossible.
Importance of plants as a food source
Plants make up the largest proportion in our diet. Plants are much more important than the larger trees for this purpose since in many countries the staple diet comes from rice or wheat.
Importance of plants to maintain the balance in the echo-system
Plants are really necessary to maintain the balance in the echo-system. For an instance plants are necessary to cycle C on the planet. CO2 in the air taken in to the plants and stored in the carbohydrates. In the present time human activities have reduced the amount of plants on the planet. So all the cycles are now changing. Because of this now the humans feel the importance of plants more and more.

Importance of plants in medicine
Plant extracts contain many chemical compounds which are biologically active within the human body. For centuries humans have used plants and plant extracts to treat various disease conditions and more recently to produce new drugs. Still most of the plants carry a large number of unidentified compounds which can be really useful of making new drugs and for the identification of lead compounds. This can be very important in making new treatments available to diseases like AIDS.

Natural foods which can cause Vitamin A toxicity

Most of the people think that it is impossible to develop vitamin toxicity by consumption of the natural foods. But this is a myth. Even though vitamin toxicity develops very rarely with natural foods but it is usually due to the oral intake of lipid soluble vitamins. There are well documented cases of acute vitamin toxicity, which developed after the consumption of certain food items. As you all know liver of any animal is responsible for detoxification of toxins and the storage of vitamins. This mechanism is really important for the storage of vitamin A and due to this most of the animal livers contain high amount of Vitamin A. But this amount in many animals is not adequate to cause acute vitamin A toxicity. But, polar bear liver, whale liver, shark liver and the lowly tuna liver may contain very high amount of vitamin A . This amount of Vitamin A may be adequate to cause acute vitamin A toxicity. First case of Vitamin A toxicity has described in 1597 by Gerrit ge Veer in the arctic. He is a carpenter and the crew of the ship he worked developed serious symptoms after eating a polar bear liver. Symptoms of acute vitamin A toxicity are headache, dizziness, vomiting, stupor and blurred vision.
Next time when you eat a polar bear liver, even though it is a great delicacy, keep in mind to eat in moderation. If you develop above symptoms after that better to seek medical attention immediately.

CPK blood test

CPK blood test

CPK blood test is very widely used for the detection of myocardial infarctions. But despite the popularity of CPK blood test for the detection of myocardial infarction it can be very effectively used to investigate and diagnose many other conditions associated with skeletal muscles. CPK-MM isoform of the CPK enzyme is predominantly found in skeletal muscle. These diseases of the skeletal muscles range from simple traumatic muscle damage to more advance muscle dystrophies. More common conditions are myositis, post electromyography, recent surgery, and strenuous exercise.
When we talk about the isoform CPK-MB it is predominantely found in cardiac myosites. When there is damage to cardiac muscle cell this isoform of CPK enzyme is released. This is another very common situation in which CPK blood test is performed. When someone is admitted to the hospital with a chest pain a CPK blood test may be performed to diagnose whether he is having a heart attack.

Importance of plants in human life?

Importance of plants in human life?
In every way humans are dependent on plants. For food, medicines, air purification, carbon cycle, nitrogen cycle and etc. But in addition to these now this has a much higher importance. It is in global warming. When the humans started burning fossil fuels carbon dioxide concentration in the atmosphere started increasing.Importance of plants in human life Carbon dioxide is a green house gas and it keeps infrared rays within the earth atmosphere and help increasing the temperature. In the upcoming years this will become more and more important in human life.
Another importance in human life is for medicines. As you all know quinine, a very potent antimalarial drug discovered from the plant cinchona. (Actually it was first discovered by an African tribe) Not humans are facing more and more challenges from emerging and re-emerging diseases. For an example HIV the most dangerous and devastating disease in the word I may say up to now does not have an effective cure. But plants may have a good answer for with. People in the Indian subcontinent and Sri Lanka have used plant extracts as very effective remedies for many conditions.

CPK Enzyme

CPK enzyme ( also known as creatine phosphokinase and creatine kinase) is the enzyme which is responsible for the conversion of creatine to creatine phosphate. CPK enzyme plays a very important in skeletal muscle since it creatine phosphate system is important for the sudden energy requirements in the skeletal muscle. CPK enzyme is also abandontely found in brain and smooth muscle. During the conversion of 1 mol of creatine to creatine phosphate CPK enzyme converts 1mol of ATP to ADP. CPK Enzyme has several isoforms. Those isoforms are CPK-BB, CPK-MB, CPK-MM. The CPK-MM type is known as the skeletal muscle type of the CPK enzyme. CPK-BB type is known as the Brain type of the CPK enzyme.Only within the myocardial cells more than 5% of CPK-MB activity can be observed. Due to this fact CPK-MB isoform of the CPK Enzyme is used to diagnose myocardial cell damage and CPk enzyme palys a major role in the diagnosis of myocardial infarctions-heart attacks. This enzyme is also important in the diagnosis of various myopathies. Usually in muscle dystrophies plasma level of CPK enzyme is elevated. To differentiate the source of CPK enzyme isoform speific enzyme assays of other markers should be used.
Eg: CPK enzyme and Troponin I in myocardial infarctions.
CPK enzyme and myoglobin in muscle damage.

Abnormal cpk levels

Abnormal cpk levels
can be due to various reasons. CPK levels are comparatively high in the skeletal muscle, heart and the brain. So any damage to skeletal muscle heart or brain can give rise to abnormal cpk levels. But in the clinical setting the most important aspects are the skeletal muscles and the heart. In the case of abnormal cpk levels in the clinical setting the term “Abnormal cpk levels” is synonymous with elevated cpk levels. (See also - elevated cpk levels) when we talk about the skeletal muscle conditions direct trauma, exercise, polymyositis, dermatomyositis, Duchenne muscular dystrophy and etc can give rise to very high cpk values. In Duchenne muscular dystrophy cpk values can be abnormal (very high) even before the actual clinical manifestation.
After a myocardial infarction damaged myocardial cells release cpk-mb isoform of the CPK enzyme. This can give rise to abnormal CPK levels in the blood. But significance of this decreases after two days. But in addition to these many other conditions can give rise to abnormal cpk levels. So before coming to a conclusion all the differential diagnosis of a particular clinical scenario should be taken into account.

CPK blood test range

If you have undergone the CPK blood test the laboratory may have provided you with a set of values. Any decent laboratory should provide the range of normal values with it. But sometimes they may not. Then you may be wondering before going to a doctor “what is the CPK blood test range? “ For you reference herewith I am providing you with the CPK blood test range. Blood please remember CPK normal values are always laboratory specific so there can be a slight deviation of the normal values I have provided here from the normal values of your laboratory.

Creatine kinase (CPK)

  • Female 24-170 U/L
  • Male 20-260 U/L
  • CK-MB fraction

There is another thing. Any value outside the normal range is not necessarily abnormal. Any value outside this range has a higher probability to be abnormal. So some values outside the normal range can be perfectly normal for some people.

Orthopedic Supplies to change your life

The term orthopedics is derived from the Greek words “orthos” and “paideion”. Orthos means “correct or straight” and “paideion means “child”. The original meaning of the word orthopedics is “to make crooked child straight”. Nowadays orthopedics is far from this original state and it has become a field where people do wonders.  In this century orthopedics doesn’t mean surgery. It covers a vast array and includes numerous methods of conservative treatment. If a joint is aching due to wear and tear it doesn’t mean always you have to go for an artificial joint replacement.  There are fascinating supports, braces and various other gadgets in the market to relieve your pain.

In Earlier days you can remember we had plaster-of-Paris back slabs we used to splint fractured limbs. Those were heavy, ugly and difficult to manipulate. Nowadays we have nice good looking material made up of fiber comes in various colors and those are light weight. These Orthopedic Supplies are developed by scientists after numerous years of research. Now we know how mechanical forces act on our body and our joins and how we should support these joints without damaging a different part of the body. Actually these new orthopedic supplies are the ones which have actually changed the field of orthopedics.
If your heel is aching due to plantar fasciitis, a soft insole for you footwear can solve the problem. Or if you are suffering from knee osteoarthritis a specifically designed knee support can help your condition. To relieve back and abdominal pain during pregnancy a maternity support belt can do a great job. How many of you are suffering from lower back pain due to mechanical problems? Most of these symptoms can be relieved by using a proper lumbosacral belt or a lumbar support. Even you can have a heat moldable insert to support the lower back spine. These plastic inserts molds directly to the skin. Conditions like cervical spondylosis are really troublesome to the patient and the amount of suffering is huge. Using a proper cervical collar for few months can reduce the symptoms to a great extent.
But the most important thing is when you choose Orthopedic Supplies you should find high quality products those can actually support you. Even though you have a large array of Orthopedic Supplies in the market choosing high quality products from great suppliers matters. Only high quality products can provide the actual service required from them or the products may wear out before the expected lifetime. Some of the companies provide extremely high quality products.

Endless possibilities with Chinese GPS

Recently I bought a Chinese GPS unit which has 7 inch display, a 600 MHz processor, 128 MB RAM and running Windows CE operating system. First I thought it as a simple GPS unit. But after going through various forums I realised that we can modify the GPS unit to do various functions. Actually manufacturers of the GPS units lock their Windows operating environment to do several defined tasks. Like GPS, calculator, movie player and MP3 player. But there is actually an Windows environment running beneath what you see. You can actually unlock it to get the maximum out of your unit. After unlocking your unit you can install software of your choice.

Back to the GPS functionality of my unit, it is actually very sensitive and has a good signal reception, it runs on SIRF 5 GPS processor. One of the best processes in the current market. My GPS is made by the company called ERODA. Their unit appeared actually very good.

Constipation and hemorrhoids

Constipation and hemorrhoids
Large number of people in the world is suffer from hemorrhoids. And most of the people think constipation is a major risk factor for hemorrhoids. Today we will talk more about this subject. According to Baily and love’s “short practice of surgery-25th edition” when stools are harder it requires more straining and more time sitting on the lavatory with relaxed perineum. This causes the venous plexus around the anus to get engorged and it could also obstruct the venous return. From this we can expect to have some association between hemorrhoids and constipation. But it is also mentioned in the same paragraph the epidemiological pattern of constipation differs from that of the hemorrhoids. So it means no association between hemorrhoids and constipation. But the current view about the hemorrhoids is that hemorrhoids are caused by shearing forces acting on the anus due to variety of reasons. But the most important thing is if a patient is suffering even from 1st degree hemorrhoids relieving constipation in that patient is a must. If the patient is having both constipation and hemorrhoids, constipation can really aggravate the symptoms of hemorrhoids. Actually patients with hemorrhoids are always advised by doctors to take more dietary fiber to normalize their bowel habits. As far as I believe according to the current view association between Constipation and hemorrhoids is a yes and a no.
