ভায়াগ্রা সেবন
একবার এক
বনে কারা যেন
ভায়াগ্রা ছড়িয়ে গিয়েছিল।
সেই
ভায়াগ্রা
সেবন
করে সকল পুরুষ
প্রানীর
যৌন কামনা ছিল তুঙ্গে।
----------------------
তারা সারাদিন তাদের
নারী সঙ্গিনীদের সাথে যৌন খেলায় মত্ত থাকত।
এক পর্যায়ে সঙ্গিনীরা
বিরক্ত হয়ে বনের রাজা সিংহের কাছে বিচার দেয়।
সিংহ মশাই গবেষনা করে
দেখেন যে ভায়াগ্রার প্রভাব
কমতে আরো এক বছর
লাগবে। তাই তিনি সকল
প্রানীকে তাদের ওটা কেটে জমা দিতে বলেন
এবং একটা করে টোকেন
দেন।কথা দেন এক বছর পর টোকেন মিলিয়ে
সবার জিনিষ
সবাইকে ফেরত দিবেন।
অন্য সব প্রানীর মত বানর ও মন খারাপ করে তার
ওটা জমা দিয়ে আসে।
বাসায় এসে দেখে যে তার স্ত্রী খুশিতে বাগবাকুম।
বানরের স্ত্রীঃ হাহা
এখন কি করবা? আগেই
বলেছিলাম......
বানরঃ বেশী হাইসো না।
একবছর পর টের পাইবা।
বানরের স্ত্রীঃ কেন??
একবছর পর কি হবে??
বানরঃ জমা তো দিয়ে
আসছি
আমার টা, টোকেন আনছি ঘোড়ার টা।
Importance of chemistry in our daily life
Importance
of chemistry in our daily life
Everything
is made of chemicals. Many of the changes we observe in the world around we see
that caused by chemical reactions. Chemistry is very important because it helps
us to know the composition, structure& changes of matter. All the matters
are made up of chemistry. In our every day like various chemical are being used
in various from, some of those are being used as food, some of those used
clanging etc.
Body is made up of chemical
compounds, which are combinations of elements. Probably know body is mostly
water, which is hydrogen and oxygen,
2.
Health Care and Beauty:
The
diagnostic tests carried out in laboratories, the prognostic estimations,
medical prescriptions, pills, the vaccines, the antibiotics play very vital
role in health monitoring, control of diseases and in alleviating the sufferings
of the humanity. Right from birth control to enhancement of life expectancy-
all have been made possible using the unequivocal services of Chemistry. From
simple sterilization surgical instruments with antiseptic solution to Chemotherapy
and Genome sequencing are all nothing but applications of Chemistry. Injecting
cows, buffaloes, goat and sheep with bovine
some towrope Increases milk-production but
it is indiscriminately being used by sportspersons to un-ethically enhance performance.
Aging- a chemical change can only be checked chemically. Most beauty products
are produced through chemical synthesis to clean, nurture and protect skins.
However their certain ingredients are hazardous to our health in the long run.
3.
Industries and Transport:
From
cloth mills, lather factories, petro-chemical industries and refineries to metal
industries- all use numerous fuels for power generation and chemical products
for processing their product and improve the equality and simultaneously
produce pollution. Now-a-days chemical effluent treatment plants use chemicals
to control or neutralist he hazardous impact of pollutants produced by the
industries. Aviation and shipping industries generate power through power plants
which burn fuels. Petrol and diesel emit out green house gases dangerous for
the survival on earth which damage the ozone layer that protects us from UV
rays. As a result global warming has taken place which is a destroyer of the
planet earth. But again Chemistry paves the way with bio-fuels.
4. Food
Security and Agriculture:
The
famous green revolution to increase agricultural produce so as to ensure food security
was triggered by the advent of inorganic fertilizers. Since then fertilizers
are extensively used by farmers to restore the fertility of soil in the fields.
Pesticides are used to protect the crop during farming and preserve the grains
from pests, rats and mice during storage. Genetically modified seeds which are used
to enhance production and earn profits through export of food grains are
agricultural applications of Bio-chemistry. Whereas refrigeration system for
cold storage of vegetables and raw meat uses Poly Urethanes Foam (PUF) and the
chemical properties of gases, the preservatives in packaged food products are
known to have adverse impact on our body.
5.
Science and Technology:
The
destructive effects of Atom Bombs dropped on Hiroshima and Nagasaki? Generations
in Japan have suffered the devastation and there has-been no solace. The threat
of weapons of mass-destruction (WMDs) like the Nuclear, Chemical and Biological
weapons looms large on the Humanity. Terrorists are using RDX and other
explosives to run currents of fear down the spines across the globe. Nuclear
reactors which are going to serve the future generations through power
generation leave us with the problem of Nuclear Waste Management. Whereas the
destructive power is generated through chains of chemical reactions, we remain
assured that Chemistry has facilitated the chain of counter measures too in the
form of safety suites and NBC resistant bunkers. Forensic science- the comprehensive
scientific analysis of material evidence in the context of the law uses
principles of chemistry to facilitate crime investigation. Tele-communications,
Information Technology and Space Missions- all bank on the chemistry of
semi-conductor sand nano-tubes.
6 Cooking
Chemistry explains how food changes as we cook it, how it rots, how to preserve food, how our body uses the food eats, and how ingredients interact to make food.
7 Cleaning
Part of the importance of chemistry is it explains how cleaning works. we use chemistry to help decide what cleaner is best for dishes, laundry, yourself, and your home. we use chemistry when use bleaches and disinfectants and even ordinary soap and water. How do they work? That's chemistry!
8 Medicine
it is very need to understand basic chemistry so that we can understand how vitamins, supplements, and drugs can help or harm us. Part of the importance’s of chemistry lies in developing and testing new medical treatments and medicines.
9Environmental Issues
Chemistry is at the heart of environmental issues. What makes one chemical a nutrient and another chemical a pollutant? How we can clean up the environment? What processes can produce the things our need without harming the environment? We're all chemists. We use chemicals every day and perform chemical reactions without thinking much about them. Chemistry is important because everything you do is chemistry! Even our body is made of chemicals. Chemical reactions occur when we breathe, eat, or just sit there reading. All matter is made of chemicals, so the importance of chemistry is that it's the study of everything.

Chemistry is present in every
aspect of life, and here we can see a few examples. There are articles about
the chemistry of everyday life, and also a few about physics, as it's also
present in our daily life
