Guava (Psidium guajava L.) is a luscious and important tropical fruit crop. It belongs to the family Myrtaceae; is ever green and hardiest among all the tropical fruit trees and exceeds most other fruit crops in productivity and adaptability and is richest source of vitamin C. The research studies were carried out at Institute of Horticultural Sciences, University of Agricultural, Faisalabad and the objectives to determine guava genetic diversity using morphological and DNA markers based approaches and to develop vegetative propagation system to avoid clonal degradation of guava. Tree parameters like growth habit, leaf shape, flowering, fruit and seed was recorded in two districts Faisalabad and Sheikhupura according to the plant descriptor. Ten plants from each accession of guava were selected for tree, leaf, fruit, flower and seed morphological analysis. Data was registered from 25 leaves/flowers/fruits/seed per accession. 15 to 20 young leaves per accession of guava were collected for DNA extraction following CTAB protocol. The extracted DNA was subjected to SSR analysis. For clonal propagation softwood cuttings from five year old trees were prepared from the tips of current season growth. IBA (0, 2000, 4000, 6000 and 8000 ppm) was used to treat cuttings for root induction. The data collected was subjected to different statistical software. During the survey 37 accessions of guava were collected from two major growing areas of district Faisalabad and Sheikhupura for phenotypic genetic variation analysis. Multivariate analysis principal component indicated high diversity for accessions Mota gola, Khata gola, Rough gola, Bangladeshi gola and Surahi in district Faisalabad and Mota gola, Larkana gola, Desi gola, Gola and Sadabahar gola were most diverse accessions in district Sheikhupura. The combined analysis of accessions of both districts indicated Mota gola (SKP), Mota gola (FSD) belonging two different orchards, Bangladeshi gola (FSD), Rough gola (FSD), Surahi (FSD), Moti surahi (SKP), Gola (SKP) and Gola (SKP) (belonging two different orchards) as most divergent accessions. Among tree parameters like, young shoot color, fully developed leaf shape of tips, fully developed leaf shape of base, fully developed leaf color, fully developed leaf curvature in cross section, thickness of outer flesh in relation to core diameter, fruit length, fruit width, fruit juiciness, fruit length of stalk, fruit length/width ratio, fruit relief of surface, fruit size of sepal, fruit sweetness, fruit diameter of calyx cavity in relation xvito that of fruit and fruit ridged collar around calyx cavity and seed size was the most diverse phenotypic markers for guava accessions identification. The phenotypic and genotypic based dendrograms grouped guava accessions into two main groups and many sub groups and sub groups. High diversity was found in all accessions especially Mota gola (SKP) was the most diverse phenotype among all accessions of both districts and Gola (SKP) had most diverse genotype on genetic basis. Sadabahar gola (SKP), Gola (SKP), Gola (FSD), Choti surahi (SKP) and Surahi (FSD) were found quite phenotypic diverse accessions in morphological analysis, and Bangladeshi gola (FSD), Lal gola (FSD), Larkana gola (FSD), Gola (SKP), Moti surahi (SKP) and Sadabahar gola (SKP) were quite genetically diverse accessions on the basis of genetic markers variation analysis. As for as clonal propagation is concerned highly significant results were obtained for all the parameters (number of rooted cuttings, sprouting % age, average number of roots per cuttings, average root length (cm) and survival % age) and all concentrations (0, 2000, 4000, 6000 and 8000 ppm) for rooting of softwood cuttings treated with IBA and NAA. Highly significant results were obtained with 4000 ppm IBA and 2000 ppm of NAA and IBA performed the best for rooting of softwood cuttings in comparison with NAA. This study revealed the great potential of morphological and genetic variation and clonal propagation technique in guava. However, a comprehensive and detailed inventory for documentation of all guava accessions, supported with gene banks and also an annexed crop catalogue needs to be carried out.

معاشی ترقی میں تعلیم کا کردار

معاشی ترقی میں تعلیم کا کردار
نحمدہ ونصلی علی رسولہ الکریم امّا بعد فاعوذ بااللہ من الشیطن الرجیم
بسم اللہ الرحمن الرحیم
معزز سامعین اور میرے ہم مکتب ساتھیو!
آج مجھے جس موضوع پر لب کشائی کا موقع فراہم کیا گیا ہے وہ ہے:’’معاشی ترقی میں تعلیم کا کردار ‘‘
جنابِ صدر!
ہر شخص یہ چاہتا ہے کہ معاشرے میں میرا مقام بلند ہو جائے ، مجھے لوگ امیر انسان تصور کریں۔ میرے مشوروں پرعمل کیا جائے ، میری رائے کو اہمیت دی جائے ، میری شخصیت مسحور کن ہوں ،میری عادات متوازن ہوں ، میر ااٹھنا بیٹھنا معیاری ہو ، میری نشت و برخاست میں آن بان اور شان کی جھلک نمایاں ہو۔ میں طلسماتی شخصیت کا مالک ہوں۔
جنابِ صدر!
ان تمام اعزازات کے حصول کے لیے درعلم و حکمت پر دستک دینا پڑے گی ، اپنی معاشی حیثیت کو بحال کرنا ہوگا، کیونکہ جس کے گھر میں خوردونوش کا سامان نہ ہو، اس کی سوچ کے انداز تبدیل ہو جاتے ہیں وہ صرف یہ سوچتا ہے کہ رات کا کھانا کہاں سے آئے گا، بچوں کا پیٹ کس طرح پالا جائے گا، بچوں کو ڈھانپنے کے لیے کپڑے کہاں سے آئیں گے۔ اس کو اور کسی بات سے غرض نہیں۔
محترم صدر!
معاشی ترقی کے لیے تعلیم اہم کردار ادا کرتی ہے۔ تعلیم کے حصول سے نہ صرف انسان معاشی طور پر مضبوط ہو جاتا ہے بلکہ اس کی ترقی مثالی ہو جاتی ہے۔ جسمانی لوازمات کو پورا کرنے کے ساتھ ساتھ تعلیم اس کو روحانی تازگی اور تراوٹ بھی فراہم کرتی ہے اور نا جائز ذرائع سے معاشی آسودگی کا خواہش مندتحصیل علم کے بعد اپنی اسی خواہش کی تکمیل میں کوشاں رہتاہے۔
لاتی ہے گلستاں میں معیشت کی یہ بہار
تعلیم کی یہ جستجو ضائع نہیں جاتی
جنابِ...

This article highlights the religious, literary and political work of Moulana ShÉista Gul famous by the name of Mathe Mulla of Khyber Puktun Khawa (1303 A. H-1401A. H. 1886A. D-1981A. D MardÉn) He was well-known scholar of Qura’n, ×adith and Fiqah, his great contribution was to promote political awareness in the community with the concept ofTwo Nations Theory by his affiliation with Muslim League under the leadership of Quaid-eAÐam Muhammad Ali JinnaÍ. He was the convener of Jamiat ul AÎfia which was organized by the eminent religious leaders of that time to implement Sharia law in Pakistan. He was devoted to make Islam a living reality during his life time, his literary work is aimed to improve human communication and develop a better understanding among the people of this region. His monumental work was originally in Pashto widely spoken and understood in the North West of Pakistan. He was teaching and preaching Islam nearly in a span of seventy years. The main objective was to alleviate the deteriorating conditions of the Muslim society and to defend it from external threats. He emphasized to bring change and correct the wrong believes and detrimental actions. His theological doctrines influenced his followers and decedents who promoted his mission in the light of writings and ideas expressed by him.

Chemiluminescence and Electrochemiluminescence Studies of Biomedical and Pharmaceutical Measurands

Early stage diagnosis plays a very crucial role in disease counteract in its very early stage before the appearance of the symptoms. Physician diagnosis depends on the outcomes arise from bio-chemical/diagnostic tests. Therefore, diagnostic methods plays vital role in right diagnosis of diseases on right time and assessing the quality of the drugs. Currently, optical measurement and chromatography based diagnostic assays are mostly used clinically. However, these assays encompass laborious sample preprocessing, complex readout instrumentation, , non-portable, time-consuming and expensive labeling methods. In contrast, electro analytical methods particularly chemiluminescence (CL) and electochemiluminescence (ECL) is one of the approaches that fit perfectly to satisfy the need of desirable characteristics of new diagnostic method. In this project, CL and ECL experiments had been accomplished using a BPCL Ultra-Weak Luminescence Analyzer. The photomultiplier tube (PMT) had been used in the BPCL Ultra-Weak Luminescence Analyzer. PMT was operated in current mode. A conventional three-electrode cell was used with a CHI 600 voltammetric analyzer to carry out electrochemical measurements. The experiments including voltamety, amperometry, ECL analysis, CL-flow injection analysis, and parameters for method validations had been done. The CL studies were performed for detection of creatinine, an important biomarker, used in clinical diagnosis and biomonitoring programs. A strong chemiluminescence was observed when creatinine reacted with H2O2 in the presence of cobalt ions, without any luminophore, enzymes and chromatographic separation. This was presented via CL-FIA method exhibiting a promising strategy for the sensitive quantification of urinary creatinine in clinical and toxicological laboratories. Hence, the CL studies have developed a novel, sensitive and selective method for detection of creatinine, to be used in clinical diagnosis and biomonitoring programs. ECL studies were designed in two parts, The first part explores new coreactants (Tripropylamine and Glucosamine) for typical luminophores and second part design a novel ECL sensor for biomedical analysis. Tripropylamine (TPrA), an eminent coreactant of tris(2,2''-bipyridine)ruthenium ion Ru(bpy)32+ ECL. The most popular coreactant for most luminol studies is H2O2, though it is very unstable and more sensitive to metal ions. In this study, a more stable TPrA was exploited as the coreactant of luminol ECL for the first time. It is anticipated that luminol–TPrA ECL system may be an attractive alternative to luminol–H2O2 ECL system for bioanalysis, immunoassays, DNA probe assays and aptasensors. Glucosamine is a bioavailable amino sugar and helps to relieve the symptoms of osteoarthritis. Glucosamine lacks chromophores (or fluorophores) which enable the sensitive detection with UV (or fluorescence). So, most available analytical methods are expensive, time consuming and need complex sample preparations. Our study investigated a new method for Glucosamine ECL analysis using another luminophore, Ru(Phen)32+ (Tris(1,10-phenanthroline)ruthenium(II) chloride). The method was validated by quantitative testing of glucosamine contents in nutraceutical products in the market. So, It shows good sensitivity, selectivity, cost effective and very fast as compared with the currently used method. Second part of ECL studies leads to development of a novel cathodic ECL sensor. It was fabricated by introducing a unique facile immobilization method of Tris (4,7-diphenyl-1,10-phenanthroline) ruthenium (II) dichloride Ru(dpp)32+ using graphite powder asimmobilization matrix. This sensor has extended potential window for ECL detecting species (DNA probes, numerous analytes such as S2O82-, oxalates and amine containing compounds)providing a novel approach for cathodic ECL as well as anodic ECL analysis in clinical chemistry and medical diagnostics. In conclusion, this project will contribute in the scientific world via a valuable addition of new analytical methods showing several logs of dynamic range, good sensitivity, fast and cost effectiveness. These characteristics provide advantages over assays that rely on radio isotopic labels, enzymatic activity, fluorescence, chromatographic and spectroscopic which have been applied in the biomedical testing and pharmaceutical analysis. However, it is foreseen that this project can be applied in the biomedical and pharmaceutical analysis for good quality and cost effective tests in future.
