Lessons Till now

I've learned that we don't have to change friends if we understand that friends change.I've learned that no matter how good a friend is, they're going to hurt you every once in a while and you must forgive them for that. I've learned that true friendship continues to grow, even over the longest distance. The same goes for true love. I've learned that you can do something in an instant that will give you heartache for life.I've learned that it's taking me a long time to become the person I want to be. I've learned that you should always leave loved ones with loving words. It may be the last time you see them. I've learned that you can keep going long after you can't. I've learned that we are responsible for what we do, no matter how we feel. I've learned that either you control your attitude or it controls you. I've learned that regardless of how hot and steamy a relationship is at first, the passion fades and there had better be something else to take its place. I've learned that heroes are the people who do what has to be done when it needs to be done, regardless of the consequences. I've learned that money is a lousy way of keeping score. I've learned that my best friend and I can do anything or nothing and have the best time. I've learned that sometimes the people you expect to kick you when you're down, will be the ones to help you get back up. I've learned that sometimes when I'm angry I have the right to be angry, but that doesn't give me the right to be cruel. I've learned that just because someone doesn't love you the way you want them to doesn't mean they don't love you with all they have. I've learned that maturity has more to do with what types of experiences you've had and what you've learned from them, and less to do with how many years you have lived.  I've learned that it isn't always enough to be forgiven by others. Sometimes you have to learn to forgive yourself.I've learned that no matter how bad your heart is broken the world doesn't stop for your grief. I've learned that our background and circumstances may have influenced who we are, but we are responsible for who we become. I've learned that just because two people argue, it doesn't mean they don't love each other And just because they don't argue, it doesn't mean they do love each other. I've learned that you shouldn't be so eager to find out a secret. It could change your life forever. I've learned that two people can look at the same thing and see something totally different. I've learned that your life can be changed in a matter of hours by people who don't even know you. I've learned that even when you think you have no more to give, when a friend cries out to you you will find the strength to help. I've learned that credentials on the wall do not make you a decent human being. I've learned that the people you care about most in life are sometimes taken from you too soon

Project trailor

It is well known that Cd is a widespread heavy metal and is released into the environment by power stations, heating systems, metal-working industries, waste incinerators, urban traffic, and cement factories and as a by-product of phosphate fertilizers (Sanità and Gabbrielli 1999). Cd has been considered as an extremely significant pollutant affecting all life forms because of its high toxicity and great solubility in soil and water. It has been demonstrated that the level of Cd in the soil appears to be increasing over time (Jones et al 1992). Cd accumulation in soil and water now poses a major environmental and human health problem (Schützrndübel et al 2001). It was reported that Cd is accumulated by many cereals, potatoes, vegetables and fruits and that humans take up at least 70% of the Cd which originates from plant food (Wagner 1993). Studies on Cd toxicity in plants are well documented. Cd can induce low mitotic index and pycnosis, inhibit cell division and cell proliferation, and has toxic effects on chromosome morphology including c-mitosis, anaphase bridges, chromosome stickiness (Liu et al 1992). Cd has toxic effect on nucleoli in the root tip cells of Allium cepa L. (Liu et al 1995) and alters the synthesis of RNA and impedes ribonuclease activity in rice (Shah and Dubey 1995). Although the toxicity and tolerance mechanisms of Cd in plants have been widely discussed at the biochemical and cell physiology levels over the last decade (Zenk 1996; Sanità and Gabbrielli 1999; Rauser 1999; Kamnev and Lelie 2000), only a few investigations have been carried out using electron energy loss spectroscopy (EELS) and cytochemical tests to localize intracellular Cd. The objectives of this investigation were to increase our understanding of the effects on root ultrastructure and Cd accumulation sites at subcellular level in the root cells of A. cepa grown in different concentrations of Cd solutions, using EELS and cytochemical tests.

               

Ø  Heavy metal toxicity

The toxicity produced by transition metals generally involves neurotoxicity, hepatotoxicity and nephrotoxicity (stohs and Bagchi,1995).Differences in solubility, absorbability, transport and chemical reactivity in these metals will lead to specific  difference in toxicity within the body (stohs and Bagchi, 1995). The chemical from of heavy metals in soil solution is dependant of the metal concerned, pH and the presence of other ions (Das et al., 1997). The toxicity symptoms observed in plants in the presence of excessive amount of heavy metals may be due to a range of interaction at the cellular level (Hall, 2002). Toxicity may result from the binding of metals to sulphydryl groups in proteins, leading to an inhibition of activity or disruption of structure (Vaan Assche and Clijter,1990).Enzymes are one of the main targets of heavy metal results in marked decreases in soil enzymes  activity (Tyler et al.,1989).Metal interaction with ligand group of enzymes largely defines their toxicity, and the inhibition of enzymes may be due to masking of catalytically active group or protein denaturation (das et al., 1997). In addition ,heavy metal excess may stimulate the formation of free radicals and reactive oxygen species (Dietz et al.,1999; Gallego et al.,1996; Groppa  et al., 2001; sandolio et al.,2001; Fornazier et al.,2002). In order to cope with highly toxic metals, or to maintain the level of essential metal with in physiological ranges, plants have evolved complex mechanisms that serve to control the uptake, accumulation and detoxification of metals.

1st One

Thats the day when I was only about 16 year old and my first Crush with her not really first one that is,there a huge no of list before that one starts at my Nursery class'es.yea tody unfortunately i write about my 1st princes.

A quote is there that about, the 1st love of your is always the best one u will gona be never-eveer forgot that one,I m also Can;t.That was the time of my life when I learn first experiance of this Great word love.But  as the time going on And I grow up my World teach me the verious faces of love. love which is the major elemant of our Blackwhole  is not so easy to Gain.U have to pay for it , it dont sale in Euros,pounds or in ruppes only the one payment for it is it himself i mean love can earn only by seeling love.


I m the one who makes several mistaks,, not only me I think Here is a rare list of people who are able keep their firsl one up.  

thougts about all around

There are some days when everything around you makes you content & blissful, this could be a touch, a song, a word, a sound, anything ..

But then there are days when same happy things suddenly looks miserable..same touch felt eerie, same song felt boring, word felt irritating, sound cause noise rather than bliss..

Days remain same..things remain same..,.then why cant mood remain same?
Why cant we remained positive always?
Why this feeling of being on an emotional roller coaster?
Why heart get hurt so easily?

If there would be something like magic band I would have asked for happiness..not only for me but for all around me...these sad feelings make me sickish...gloomy faces made me cry..why cant everyone be happy...no liars no cheaters just happy souls all around
