Research was conducted on rice crop to see the impact of rice bug Leptocorisa oratorius on yield, quality and crop value at adoptive research station Vehari, Punjab, Pakistan. The studies showed that L. oratorius attacks on rice plant and produce unfilled grains. During research process, the infestation level of rice bug was observed on four rice varieties, Basmati-385, 11 Basmati-386, Basmati-2000 and Super-Basmati to see the effect of rice bug on rice plant and percentage of damaged rice plants were also observed. Results have shown that in potential grain loss, maximum 420 grains were damaged at 6 levels in Basmati-2000 while minimum were recorded 210 grains/30 days of intervals in Basmati-386. While the effect of bug on grain yield produced was maximum and 37% unfilled grains with bug?s density and maximum loss was occurred 11% at level 9 and maximum grains were present 475/m at 0 levels. Similarly maximum 100 grains weights were found in Basmati-386. Grain % with feeding sheath was recorded 85% in Basmati-385 and Basmati-2000 while 65% in Basmati-386 and maximum 95% seed germination was found in Basmati-2000 at 0 levels and minimum 31% at 9 levels. It was observed that L. oratorius nourished on rice plant and formed empty and incompletely filled grains. At the same degree of invasion, Basmati-386 and Super-Basmati had greater harvest, less injured grain, and more growth amounts than Basmati-2000, Basmati-385 in which rice bug were attacked more and these plants allowed rice bug nourishment. Results have shown that rice bug L. oratorius attacks on rice plant and nourished on fluid of stem and seed of rice. Rice bug mainly attacks at flowering and milky stage of spikelets. It was observed that when rice bug attacks on rice plant, 21% of rice yield reduced by rice bug L. oratorius in calculation to poor grain yield and low development percentage

ٹیلی ویژن کی اہمیت

ٹیلی ویژن کی اہمیت
نحمدہ ونصلی علی رسولہ الکریم امّا بعد فاعوذ بااللہ من الشیطن الرجیم
بسم اللہ الرحمن الرحیم
معزز سامعین اور میرے ہم مکتب شاہینو!
آج مجھے جس موضوع پر اظہار خیال کرنا ہے وہ ہے:’’ٹیلی ویژن کی اہمیت‘‘
جنابِ صدر!
ترقی انسان کا مقدر ہے، یہ انسان ہمیشہ سے آگے بڑھتا آیا ہے مختلف قسم کی ایجادیں ہوئیں، مختلف حوالوں سے ترقی ہوئی ،مختلف شعبوں میں انسان نے ترقی کیلئے سرتوڑ کوشش کی اور پھر اس میں کامیابی حاصل ہوئی، انسان کو وہی کچھ ملتا ہے جس کے لیے جتنی کوشش کرتا ہے ،جتنی کدوکاوش کرتا ہے، اس کو اس کی محنت کا پھل اللہ تعالیٰ ضرور عطا فرماتا ہے۔
صدرِذی وقار!
کچھ عرصہ قبل کی بات ہے کہ ریڈ یوکی ایجاد نے دنیا کو ورطۂ حیرت میں ڈال دیا، اس میں ترقی ہوئی تو ٹیلی ویژن ایجاد ہو گیا، ٹیلی ویژن کی ایجاد ایک اہم ایجاد ہے ، ریڈیو نے کائنات کی وسعتیں اور فاصلے سمیٹے اور انسانی آوازوں کو ہزاروں میلوں تک پہنچایا توٹیلی ویژن نے اس سے بڑھ کر کام کیا ، اس نے ایک قدم اور آگے بڑھایا۔ آپ ٹیلی ویژن میں انسانوں کو گفتگو کرتے اورمتحرک دیکھ سکتے ہیں۔
صدرِ محترم!
ہم ٹیلی ویژن میں انسانوں کو اپنی آواز میں ، ان کی اپنی شکل وصورت میں، ان کے اپنے رنگ ڈھنگ میں، ان کے اپنے طور طریقوں میں دیکھ سکتے ہیں، ٹیلی ویژن کی ایجاداس جدید دور میں ایک نعمت سے کم نہیں ہے۔ مختلف پروگرام پیش کرتا ہے۔ مختلف علاقوں کی ثقافت سے متعارف کرواتا ہے، مختلف علاقوں کے خوبصورت مناظر سے قاری کی قوت بصارت کوتقویت دینے کا سبب بنتا ہے،تفریح کے مواقع پیش کرتا ہے۔
معزز سامعین!
پاکستان میں ٹیلی ویژن کی ابتدا1964ء میں ہوئی ، ٹیلی ویژن کے...

عصر حاضر میں بین المذاہب ہم آہنگی کی ضرورت و اہمیت

The enmity and differences among nations have risen along with the increasing distances among people. Therefore, the need of hour is to develop the spirit of harmony and understanding among the followers of revealed religions. The Messengers and Prophets were designated by Allah to promote and promulgate, justice, tolerance, love and harmony among His creations. Islam is a religion based on characteristics of peace, love, respect, tolerance, dignity and denial of extremism, which are in the contemporary world ideal for interaction among nations. Islam teaches to respect all the religions and prophets to maintain and sustain the peace and harmony. The advanced technology of modern world and inventions demand intense responsibility to maintain and enhance the better human relations in Political, Social, Economic, Religious, and Cultural spheres of life. The present article envisions all those dimensions, which are essential for interfaith harmony.

Inequalities for Bregman and Burbea-Rao Divergences and Related Results

Mathematical inequalities play an important role in almost all branches of mathe- matics as well as in other areas of science. The basic work ”Inequalities” by Hardy, Littlewood and Polya appeared 1934 and the books ”Inequalities” by Beckenbach and Bellman published in 1961 and ”Analytic inequalities” by Mitronovic published in 1970 made considerable contribution to this field and supplied motivation, ideas, techniques and applications. This theory in recent years has attached the attention of large number of researchers, stimulated new research directions and influenced various aspect of mathematical analysis and applications. Since 1934 an enormous amount of effort has been devoted to the discovery of new types of inequalities and the ap- plication of inequalities in many part of analysis. The usefulness of Mathematical inequalities is felt from the very beginning and is now widely acknowledged as one of the major deriving forces behind the development of modern real analysis. This Ph.D thesis deals with the inequalities for Bregman and Burbea-Rao divergences and some of its related inequalities, namely Jensen’s inequality, majorization inequality, Slater’s inequality and inequalities obtained by Mati ́ and Peˇari ́. c c c The first chapter contains a survey of basic concepts, indications and results from theory of convex functions and theory of inequalities used in subsequent chapters to which we refer as the known facts. In the second chapter we give an improvement of Jensen’s inequality for convex monotone function and various applications for related inequalities and divergences. ˇ In the third chapter we give Sapogov’s extension of Cebyˇev’s inequality and use this extension to prove majorization inequality. We also give mean value theorems for majorization inequality. As application, we present a class of Cauchy’s means and prove logarithmic convexity for differences of power means. In the fourth chapter we generalize some results of Mati ́ and Peˇari ́. We use a c c c log-convexity criterion and establish improvements and reverses of Slater’s and related inequalities. In the fifth chapter we give Bregman and Burbea-Rao divergences for double in- tegrals and matrices. We derive mean-value theorems for the divergences induced by C 2 -functions. As application, we present certain Cauchy type means. We prove pos- itive semi-definiteness of the matrices generated by these divergences which implies exponential convexity and log-convexity of the divergences. Also show the mono- tonicity of the corresponding means of Cauchy type. At the end we consider integral power means. In the sixth chapter we give several results for functions of two variables and majorized matrices by using continuous convex functions and Green function. We prove mean value theorems and give generalized Cauchy means. We give applications of those generalized means and show that they are monotonic. We prove positive semi-definiteness of matrices generated by differences deduced from the majorization inequalities for double integrals and majorized matrices which implies exponential convexity and log-convexity of these differences.
