شخصيت انسانى پر شہادتين كے قرآنى اثرات

Allah Almighty sent mankind in this world for His worship only. This is high right on humans those who keep the faith and belief in the one Supreme God and obey His orders. When they followed satanic powers, they forgot the eternal lesson of Tawheed (Oneness of Allah) and engaged Shirk (polytheism). It is the dogma of Oneness of Allah with which mankind gets tranquility and peacefulness in society and becomesconstructive and valuable for humanity. And when human left his belief on Allah, they germinate their negative role and made the society despicable. In this scenario Allah Almighty sends His prophets to those nations which create mess and fill the society with clutter. At that time prophets play their role as a bounty of Allah on human race. They purify people by their teachings granted by Allah and focus their attention to the eternal massage of God. So Eman (faith) on prophet hood considered as essential as belief on Oneness of Allah. Both these beliefs; Tawheed and Risallah effect human life prominently in such a way that man redevelops his whole personality and becomes a required sound character of Eman. Then worldly contamination cannot harm human being's decency and he becomes a felicitous character of vigorous society.

Time Course Changes in Metabolite Accumulation and Their Implications for Heat Stress Tolerance in Maize Zea Mays L. Seedlings

Maize shows reduced crop stand under relatively suboptimal conditions, the main reason for this is sensitivity of bud tissue to temperature fluctuations and salinity at sowing time. The aim of these studies was to explore the physiological and biochemical occurring at seedling stage in a time course manner. The determinations were made on growth, photosynthetic pigments, accumulation of osmolytes, oxidative damage and antioxidants, secondary metabolites and nutritional quality characteristics in shoot and root of two differentially heat stress tolerant varieties of maize. Results revealed that reduction in length, fresh and dry weight of shoot and root and loss of chlorophylls and carotenoids in the leaves were the explicit determinants of heat damage. The heat tolerance of maize was associated to greater accumulation of glycinebetaine followed by free proline. As evident from H 2 O 2 and MDA data, heat stress produced oxidative stress on both the varieties, although lowly in the tolerant one. Enhanced or steady state levels of niacin, ascorbic acid and riboflavin and enhanced ability of reducing powers led to the alleviation of oxidative damage on the maize plant. Among the secondary metabolites, enhanced synthesis of flavonoids and anthocyanins and saponin was closely related to the heat tolerance of maize. As for nutritional quality characteristics, heat stress reduced the crude fiber, starch, oil and proteins contents and led to an overall reduction in the accumulation of nitrate, phosphate and K, and led to a hampered nutritional value and metabolizable energy in both the varieties, but tolerant maize was superior for these attributes. In short, heat tolerance in maize was associated greater photosynthetic pigments levels and better metabolic adjustment, which resulted in better nutritional quality of the vegetative parts for use as fodder for the animals. All these changes were more precise in the shoot.
