Food Habit / 10 Bad Habits that Damage Brain

« on: January 23, 2013, 09:37:08 AM »

I am not sure whether this has already been published or not. Rather I wish to post this again for awareness.

 
ব্রেইন ধ্বংসকারী ১০টি অভ্যাস :

সন্দেহ নাই আমাদের শরীরের সবচেয়ে মূল্যবান অংশ হচ্ছে আমাদের ব্রেইন। সবাই আমরা চাই আমাদের ব্রেইনের ক্ষমতা ক্ষুরধার থাকুক। তাই ব্রেইনের জন্য সবচেয়ে ক্ষতিকর ১০টি অভ্যাস দেয়া হল। তরুণ বয়স থেকে ধ্বংসাত্বক অভ্যাস থেকে নিজেকে দূরে না রাখতে পারলে ব্রেইন অকালেই বুড়িয়ে যাবে।

১. সকালে নাশতা না করা -
অনেকেই ব্যস্ততার কারণে সকালের নাশতা না করেই বাসা থেকে বের হয়ে যাই। কিন্তু এই অভ্যাসটা ভালো নয়। কারণ সকালে নাশতা না করলে নিম্ন রক্তে গ্লুকোজস্বল্পতার কারণে ব্রেইন পর্যাপ্ত পুষ্টি পায় না। এতে ধীরে ধীরে ব্রেইন মারাত্মক ক্ষতিগ্রস্ত হয়। তাই সকালের নাশতা করতে ভুলে যাবেন না।

২. অতিরিক্ত খাবার গ্রহণ -
অনেক সময় প্রয়োজনের অতিরিক্ত খাবার খেয়ে ফেলি। মনে হয় মাঝেমধ্যে একটু বেশি খেলে কী আর হবে! কিন্তু অতিরিক্ত খাবার গ্রহণের অভ্যাস আমাদের ব্রেইনের রক্তনালির ইলাস্টিসিটি নষ্ট করে দেয়। ফলে অনেক ধরনের মানসিক সমস্যার উৎপত্তি হতে পারে।

৩. ধূমপান -
ধূমপানের ক্ষতিকর প্রভাব বলে শেষ করা যাবে না। তাই যারা ধূমপান করেন, তাদের জন্য সতর্কতা-ধূমপানে কেবল ফুসফুস ক্যান্সার নয় বরং এতে করে ব্রেইন সংকুচিত হয়ে যায়। ফলে আলঝেইমারস নামের স্মৃতি বিলোপকারী রোগেরও উদ্ভব হতে পারে।

৪. অতিরিক্ত মিষ্টি গ্রহণ -
অনেকের ধারণা মিষ্টি বেশি খেলে ব্রেইন ভালো থাকে। কিন্তু অতিরিক্ত মিষ্টি খেলে সেটা আমিষ ও অন্যান্য পুষ্টি উপাদানের পরিপাক ও শোষণে বাধা সৃষ্টি করে যা ব্রেইনের ওপর ক্ষতিকর প্রভাব ফেলে এবং ব্রেইনের বিকাশ সাধনের অন্তরায় হয়ে দাঁড়ায়।

৫. বায়ুদূষণ -
বায়ুদূষণের জন্য ব্রেইনের কার্যক্ষমতা ধীরে ধীরে কমে যায়। দূষণের ফলে অক্সিজেনসমৃদ্ধ বাতাস আমাদের ব্রেইনে যেতে পারে না। ফলে ব্রেইন ধীরে ধীরে পুষ্টির অভাবজনিত স্বাভাবিক কার্যকর ক্ষমতা হারাতে থাকে। তাই বায়ুদূষণযুক্ত পরিবেশ থেকে দূরে থাকুন এবং বায়ুদূষণরোধে নিজেও অন্যকে সচেতন করুন।

৬. নিদ্রাহীনতা -
ঘুম ব্রেইনের বিশ্রামের জন্য জরুরি। তাই পর্যাপ্ত ঘুম ব্রেইন কোষের স্বাভাবিক কার্যাবলি নিয়ন্ত্রণের জন্য গুরুত্বপূর্ণ। যারা দীর্ঘদিন ধরে নিদ্রাহীনতায় ভুগছেন কিংবা কাজের ব্যস্ততার জন্য ঘুমানোর জন্য পর্যাপ্ত সময় পাচ্ছেন না-তারা সতর্ক হোন। কারণ নিদ্রাহীনতা ব্রেইনের কোষের মৃত্যুর জন্য দায়ী। সুতরাং পর্যাপ্ত ঘুমকে কেবল সময় নষ্ট হিসেবে নয়, বরং ব্রেইনের বিশ্রামের জন্য দরকারি হিসেবেও নিন।

৭. ঘুমানোর সময় মাথা আবৃত করা -
অনেকে লেপ, কাথা বা চাদরে মাথা মুড়ে ঘুমান। এটা ব্রেইনের জন্য ভালো নয়। কারণ মাথা আবৃত করে ঘুমালে নিঃশ্বাসের কার্বন ডাই-অক্সাইড ঘনীভূত হয় এবং অক্সিজেনের পরিমাণ কমে যায়। এতে ব্রেইনের ক্ষতি হয়।

৮. অসুস্থ শরীরে অতিরিক্ত কাজ -
যখন অসুস্থ হই, তখন উচিত কোনো পরিশ্রমী কাজ অথবা পড়াশোনা থেকে বিরত থেকে ব্রেইনকে বিশ্রাম দেয়া। তা না হলে অসুস্থতার সময় অতিরিক্ত চাপ ব্রেইনের কার্যক্ষমতা কমিয়ে দেয়। ফলে ব্রেইনের দীর্ঘমেয়াদি মারাত্মক ক্ষতিসাধন হয়।

৯. চিন্তা না করা -
বেশি বেশি চিন্তা করুন, ব্রেইন কোষের উদ্দীপনার জন্য চিন্তা-ভাবনা করা অত্যন্ত জরুরি। যত বেশি সৃষ্টিশীল চিন্তায় মনোযোগ দিতে পারবেন, তত বেশি আপনার ব্রেইন কোষ উদ্দীপিত হবে। আপনি আরও বেশি দক্ষ ও মনোযোগী হতে পারবেন যেকোনো কাজে। কারণ চিন্তাহীন ব্রেইন ধীরে ধীরে সংকুচিত হয়ে ব্রেইনের কার্যক্ষমতা নষ্ট করে দেয়।

১০. কথা কম বলা -
চুপচাপ থাকাও ব্রেইনের জন্য ক্ষতিকর। কারণ যত বেশি বুদ্ধিবৃত্তিক আলোচনায় অংশ নিতে পারবেন, সেটা ব্রেইনের স্বাভাবিক দক্ষতা বৃদ্ধির জন্য তত কাজে লাগবে। তাই চুপচাপ নয় বরং কার্যক্ষেত্রে বেশি বেশি আলোচনায় অংশ নিয়ে ব্রেইনকে সতেজ রাখুন।

Health Tips / Tips to Keep Bugs from Biting

« on: January 21, 2013, 04:51:38 PM »

Tips to Keep Bugs from Biting:

    1. Protect your child by covering that delicate skin with lightweight, long sleeved shirts, long pants and socks. Insects may be attracted to floral prints. Choose light, solid colored fabrics.

    2. Mosquitoes are usually most active at dusk and just before dawn. Avoid playing outside during these peak hours.

    3. Keep your window and door screens in good repair. When possible keep your child protected indoors or behind mosquito netting.

    4. If eating outside, use an outdoor fan to blow away mosquitoes.

    5. To reduce mosquito breeding near your home, plant scented geraniums, lemon thyme, marigold, tansy, citrosa plants, sweet basil and/or sassafras.

    6. Eliminate common mosquito breeding sites such as sources of standing water (old tires, pools, plastic pots, buckets, garbage cans or clogged roof gutters). Change water in birdbaths every other day.

    7. Make your yard friendly for natural predators such as ladybugs, bats, dragonflys, praying mantis, spiders and birds. Stock a pond with goldfish or freshwater minnows.

    8. Use yellow light bulbs (non-attractive, to bugs) in outdoor fixtures.

    9. Fragrances attract insects. Avoid using scented products (such as soap or shampoo) on your child or yourself.

    10. Choose safer bug repellent products (but consider efficacy if you have local insect-borne disease risks.) SafeMama.com has a great guide to natural bug repellents.

Positive Thinking / Try to be positive

« on: January 15, 2013, 03:24:50 PM »

A few common strategies involve learning how to identify negative thoughts and replacing these thoughts with more positive ones. While it might take some time, eventually you may find that thinking positively starts to come more naturally. Consider putting some of the following tips into practice.

Avoid Negative Self-Talk

Self-talk involves the things you mentally tell yourself. Think of this as the inner voice inside your mind that analyzes how you perform and interact in the world around you. If your self-talk centers on negative thoughts, your self-esteem can suffer. When you start thinking critical thoughts about yourself, take a moment to pause and assess.

Elizabeth Scott, About.com's Guide to Stress Management, has some great tips for how to turn negative self-talk into positive self-talk. She advises readers to start by noticing their thought patterns and then focus on changing these into more positive ones. When you catch yourself engaging in a negative thought, mentally telling yourself to "Stop" can help break the pattern.


Try Humor

It can be really difficult to stay positive when there is little humor or lightness in your life. Even when you are facing challenges, it is important to stay open to laughter and humor. Sometimes, simply recognizing the potential humor in a situation can lessen your stress and brighten your outlook. Seeking out sources of humor such as watching a funny sitcom or reading jokes online can help you think more positive thoughts.


Cultivate Optimism

Learning to think positive is like strengthening a muscle; the more you use it the stronger it will become. Researchers believe that your explanatory style, or how you explain events, is linked to whether you are an optimist or a pessimist. Optimists tend to have a positive explanatory style. If you attribute good things that happen to your own skill and effort, then you are probably an optimist. Pessimists, on the other hand, usually have a negative attributional style. If you credit these good events to outside forces, then you likely have a more pessimistic way of thinking.

The same principles hold true for how you explain negative events. Optimists tend to view bad or unfortunate events as isolated incidences that are outside of their control, while pessimists view such things as more common and often blame themselves. By taking a moment to analyze the event and ensure that you are giving yourself the credit you are due for the good things and not blaming yourself for things outside of your control, you can start to become more optimistic.
Keeping Working On It

There is not on-off switch for positive thinking. Even if you are a natural-born optimist, positive thinking can take effort in the face of challenging situations. Like any goal, the key is to stick with it for the long-term. Even if you find yourself dwelling on negative thoughts, you can look for ways to minimize negative self-talk and cultivate a more optimistic outlook.

Finally, do not be afraid to enlist the help of friends and family. When you start engaging in negative thinking, call a friend or family member who you can count on to offer positive encouragement and feedback. Remember that in order to think positively, you need to nurture yourself. Investing energy into things you enjoy and surrounding yourself with optimistic people are just two ways that you can encourage positive thinking in your life.

Fast Food / 10 Negative Health Effects of Fast Food

« on: September 25, 2012, 12:40:45 PM »

The ill effect of fast food and the potential danger that it possesses by its regular consumption is shocking. Obesity, increase in cholesterol levels, nutritional deficiencies, cardiac disorders, loss of muscle mass, depression and even sexual dysfunction, can all be caused by eating fast food on a regular basis. Soaked in trans fat and loaded with calories, fast foods are labeled as 'health hazards' by many leading medical professionals.

10 Negative Health Effects of Fast Food

#1 - Headaches
The processed meat used in fast food contain nitrates, nitrites, artificial sweeteners and monosodium glutamate which increase blood flow and can trigger a migraine attack. Additives are used to keep the meat fresh and to prevent the growth of Clostridium botulinum the bacteria which causes food poisoning. The increased blood flow can cause excessive pressure to build up in the head and can lead to headaches or a feeling of a hangover.

#2 - Collection of Trans Fat
The processed food used in the fast food industry is loaded with trans fat, which not only increases the 'bad cholesterol' (Low Density Lipoprotein) levels but also reduces the 'good cholesterol' (High Density Lipoprotein) levels. Processed meat used by fast food industries can sometimes have 45% more trans fat than their natural counterparts.

#3 - Increased Cholesterol Levels
Consuming fast foods leads to an increased intake of cholesterol which is highly dangerous for humans. The cholesterol molecules attach themselves to the arteries which leads to their thickening or clogging. This can cause obstructed blood flow which can lead to high blood pressure. If cholesterol accumulates in one of the main arteries it can lead to a blockage, when an artery is completely blocked it can lead to heart attacks or complete heart failure.

#4 - Depression
Depression is one of the many negative effects of fast food. This emotional condition has been linked to regular consumption of fast foods by a study done by the University College of London. According to the study, people who indulge in fast foods regularly are 58% more likely to suffer from depression. Fast foods do not contain antioxidants, foliate and omega -3s which is necessary for good mental health. Fast foods contain preservatives, emulsifiers, thickeners, stabilizers and flavor enhancers which can affect the mental well-being of the person.

#5 - Excessive Sodium Intake
Fast foods contain high amounts of sodium which can lead to hypertension and high blood pressure. Although small amounts of sodium is needed for bodily functions, consuming too much can lead to not just high blood pressure, but build up of fluids in people who are suffering from liver cirrhosis, congestive heart failures or kidney ailments.

#6 - Sexual Dysfunction
What we eat affects our physical, mental, and sexual health. Fatty acids found in fast foods are a major contributor to sexual dysfunction, not only does it cause weight gain but can trigger biochemical changes which effect libido, sperm count and female ovulation.

#7 - Food Poisoning
Even if we overlook the dangers posed by low fiber, trans fat and high calories, fast food pose another problem, food poisoning. The processed meat is many times contaminated with manure which contains Escherichia Coli and Salmonella. E.Coli is considered very difficult to treat and sometimes referred to as the worst sort of food poisoning. Even after antibiotics kill the bacteria, the toxins released by it can produce harmful effects. This disease is usually spread through undercooked hamburgers and is a leading cause of renal failure among American kids.

#8 - Addictive Nature of Fast Foods
According to the Science Daily, high levels of sugar and fat can cause blood sugar to spike and then crash suddenly. The patrons of fast food feel a sudden rush of euphoria when this happens making them dependent on the euphoric effects of insulin surges. Therefore one of the harmful effects of fast food consumption is the addiction or the incessant craving it causes among people.

#9 - PFCA Contamination
The wrappers used in the fast food industry are coated with perfluoroalkyls (PAC) which prevents the grease from leaving through. These have been proven to get inside the human body and change into more harmful forms which can lead to many health complications. The wrappings used in fast food industry are a significant and indirect source of PFCA contamination.

#10 - Weight Gain
Studies have found a direct link between fast food consumption and weight gain and increased Body Mass Index (BMI). The high levels of trans fat and calories present in fast foods leads to accumulation of abdominal fat and even insulin resistance which is an early indicator of diabetes. Obesity has been ranked the number one health threat for Americans; it is also the second leading cause of preventable death in United States which claims up to 400,000 lives a year. Obesity can lead to type 2 diabetes, heart problems, hypertension, blocked arteries, increase in cholesterol levels, malnutrition, loss of muscle mass and depression.

Fast food addiction can lead to an unhealthy and depressive sedentary lifestyle; to prevent this, it's recommended to switch to a healthy and balanced diet along with regular exercise. Remember the key to happiness is a healthy lifestyle.

Orientations / Orientation program, Fall'12

« on: September 25, 2012, 11:05:29 AM »

The Orientation Program of newly admitted under graduate students of Fall semester 2012 has held on 24 September. I joined that program and found that it was very much informative for the freshers.
There were some nice power point presentations on the rules and regulations of the university which will definitely help them to cope up with the new place easily.

From this program the new comers also get a clear suggestions about the facilities those the varsity has already arranged for them.  There is nothing to be panicked here if the students maintain the existing rules.

We all welcome them to the DIU family.

Software Industry in Bangladesh / Bangladesh in the 4th position

« on: September 20, 2012, 01:09:50 PM »

Software export earning likely to rise by 30% in 2011-12
 
DHAKA, Dec 10 (BSS) - Bangladesh expects to earn 30 percent more foreign currency through software export compared to the amount the sector fetched last year as ICT is growing in line with the government's Vision 2021, officials and ICT business sources said.

Bangladesh Association of Software and Information Services (BASIS) officials said Bangladesh earned around US$ 45 million through software export last year in official channel but the amount could be as high as $100 million as the outsourcing through freelancing was not included in the official data.

"BASIS expects the amount to increase by some 30 percent this year (2011)," vice president of the apex body of ICT business Fahim Mashroor told BSS.

BASIS officials said the country now exports different kinds of software and ICT enabled services for different programmes including cell phone applications, data entry, graphic and web design to 23 destinations abroad with the United States, Japan, Denmark and Netherlands being the major recipient countries.

"Out of our 467 members, 150 are directly involved in software exports," BASIS president Mahboob Zaman said.

At the same time, the country secures a strong position globally as an outsourcing country with Odesk, a leading global platform of ICT business through outsourcing, registering Bangladesh in the fourth position in the list of nations offering the outsourced services after the Philippines, China and India.

Mashroor, also the chief executive officer of bdjobs.com, said currently some 10,000 young IT experts were offering the ICT
services as freelancers and many of them monthly earn as high as
$10,000 working at their homes and offices.

"But lack of internet speed remained to be major barrier . .
.high speed internet connectivity and ICT infrastructure is
mandatory for the expansion of the sector," he said.

Earlier this year, Bangladesh was named as one of the world's
best 30 IT outsourcing destination by ICT watchdog Gartner.

Astronomy / Twinkle twinkle little star!!

« on: September 20, 2012, 12:57:27 PM »

Stars twinkle because their light passes through various levels of our atmosphere, as the air moves at different levels or layers, the light is bent, which looks like twinkling to those of us on the ground? Pictured from space, do you think stars twinkle?

If you were aboard the space shuttle or International Space Station, you would not see the stars twinkle.

The light from planets also travels through that same atmosphere to you, but light from the wider disks of planets is not as disturbed as the changes between atmospheric levels cancel each other out. That's why, as seen from Earth, planets shine with a steady light.

Life Science / Use technology in healthy way

« on: September 19, 2012, 04:53:27 PM »

Technology, whether we want it or not, had been an inevitable part of our life and you can do nothing without using your mobile phone or the personal computer in your day to day life activities. Even the trend of laptops had given way to the new technology of palm tops, tablets and e-readers. And, with every growing tech accessories it is nothing but a man’s health is what is at indefinite risk.
What you should and what you shouldn’t do? Here are some tips on how tech could be using without harming your body…

Prolonged exposure

Eyes are the first target for any tech enthusiast and most of them wear glasses with high power even at young ages. We can try correcting it with refractive surgery but the eyes will become even more sensitive after laser treatment and when you stare at the brightly lit LED for hours, they are sure to get all watery and damage the eyeballs.
Never use the highest brightness level in any monitors, tablets or e readers.

Always use safety strip covers on the LED lit panel as it not only helps to make it scratch proof but also obstruct sharp rays from reaching your eyes.

Never look at displays in absolute darkness. If so, use lowest possible brightness level and strongly stop using it for hours together.

Hear pleasant

Music quality had been improvised two fold since the olden days and even tiny speakers relate high quality music with loud bass along with shrill, crisp treble quality. It all sounds good on paper but when you start meddling with the equalizer settings for optimum quality, the player might be Ready but not your ears. Ear drums are most sensitive to sound and when you use thumping noise millimeters from the drum at high frequency, it will lead to serious disasters.
Never set the volume level too high. Moderate is preferable.

Bass settings should be minimal as it is meant to be on the exterior, not on in ear headphones.
Never hear hard rock or loud noise like music for hours. They can damage your brain and its thinking power immensely, says a research crew.

Don’t go to sleep with music on and ear phones stuck close. They will block your ear for free air flow and also not advisable.
Try to listen using speakers outside at regular intervals to avoid pressure on ears.

Astronomy / 10 Strange and Amazing Astronomy Facts

« on: September 19, 2012, 04:18:22 PM »

Even though man has studied the heavens for thousands of years, we still know very little about the Universe we live in. And as we continue to learn more, we are consistently amazed, and sometimes confused, by what we learn. Here is a collection of amazing, interesting, and strange astronomy facts, in no particular order.

    * Scientists believe that we can only see about 5% of the matter in the Universe. The rest is made up of invisible matter (called Dark Matter) and a mysterious form of energy known as Dark Energy.

    * Neutron stars are so dense, that a soup can full of neutron star material would have more mass than the Moon.

    * The Sun produces so much energy, that every second the core releases the equivalent of 100 billion nuclear bombs.

    * Galileo Galilei is often incorrectly credited with the invention of the telescope. Instead, historians now believe the Dutch eyeglass maker Johannes Lippershey as its creator. Galileo was, however, probably the first to use the device to study the heavens.

    * Black Holes are so dense, and produce such intense gravity, that even light can not escape. Theoretical physicists predict that there are situations under which light can escape (which is called Hawking radiation).

    * Light from distant stars and galaxies takes so long to reach us, that we are actually seeing objects as they appeared hundreds, thousands or even millions of years ago. So, as we look up at the sky, we are really looking back in time.

    * The Crab Nebula was produced by a supernova explosion in 1054 A.D. The Chinese and Arab astronomers at the time noted that the explosion was so bright, that it was visible during the day, and lit up the night sky for months.

    * Shooting stars are usually just tiny dust particles falling through our atmosphere. Comets sometimes pass through Earth’s orbit, leaving trails of dust behind. Then as Earth plows through the dust in its path, the particles heat up, creating the streaks in the night sky.

    * Even though Mercury is the closest planet to the Sun, temperatures can reach -280 degrees F. Why? Since Mercury has almost no atmosphere, there is nothing to trap heat near the surface. So, the dark side of Mercury (the side facing away from the Sun) is very cold.

    * Venus is considerably hotter than Mercury, even though it is further away from the Sun. The thickness of Venus’ atmosphere traps heat near the surface of the planet.

Time Management / Blocks of study time and breaks

« on: September 18, 2012, 03:27:27 PM »

As your semester begins and your course schedule is set, develop and plan for, blocks of study time in a typical week. Blocks ideally are around 50 minutes, but perhaps you become restless after only 30 minutes? Some difficult material may require more frequent breaks. Shorten your study blocks if necessary-but don't forget to return to the task at hand! What you do during your break should give you an opportunity to have a snack, relax, or otherwise refresh or re-energize yourself.

For example, place blocks of time when you are most productive: are you a morning person or a night owl?

Jot down one best time block you can study. How long is it? What makes for a good break for you? Can you control the activity and return to your studies?
