A research project was initiated at the Agricultural Research Institute, Dera Ismail Khan, NWFP, Pakistan during 2002 and 2003; to provide appropriate rice cultivation technologies that are agronomically practicable and economically viable under the agro-climatic conditions of the area. The research project was based on field-oriented problems faced by the paddy growers, which was also evident from face to face interviews by 50 rice growers, actively involved in rice production from major rice growing villages of the area. field experiments relating to time of transplanting and number of seedlings hi!r'' and techniques for weed control in transplanted and direct wet-seeded rice were laid out in Randomized Complete Block Design (RCBD) with split-plots arrangements, replicated 4 times. The transplanting dates of nursery and methods of planting were maintained in main plots while the number of seedlings hill" and weed control techniques were kept as sub-plots. The sub-plot size was 2 x 5 m" The trial pertaining to impact of seeding techniques in transplanted and direct wet-seeded rice was deSigned in RCB with a plot 3 x 5 m2, replicated 4 times. Well-adapted coarse rice variety IR-6 was used in the research project. Thirty days old rice nursery was used in transplanted plots while wet pre-germinated seed was broadcast in direct seeded plots. Data were recorded on various growth and yield parameters like plant height (em), productive tillers m-'', unproductive tillers m-'', panicles m-'', spikelets panicle-" sterility and normal kernels percentage, 1000-grain weight (g), paddy yield (t ha'') and straw yield (t ha'') The data were also recorded on leaves planr'', leaf area index (LAI), net assimilation rate (NAR) at 45 and 90 days after sowing (DAS), stem borer moths'' resting behaviour at 30, 45 and 60 DAS and white heads planr'' after 90 DAS in all experiments of the project. The sample size in experiment 1 was determined by using simple random sampling procedure of probability sampling. A sampling frame was developed that carried details of farmers involved in rice production. This was identified by collecting information from the key informants. The findings of the survey elucidated that water shortage, high cost of inputs, non-availability of skilled labour during peak planting season, sub-optimal plant population, weeds and pest infestation, high dependence xiv of knowledge on nearby growers and low price of nce in Ihe locel markel were the major restrictions in higher yields of rice, In experiment 2, the effects of transplanting dates and number of seedlings hilr'' were found 10 be significant in most of the agronomic and physiological parameters studied The highest paddy yield during 2002 and 2003 (5 and 8,1 t ha") respectively, higher net return of Rs, 7,830 and 23,330 /la"and Benefil Cost Ralio (BCR) of 0.44 and 1,32 were recorded on 20''h June planted crop with 1 seedling hiW'' during both the expenmental years, Similarly in experiment 3, the effect of planting tec/1niques (transplanting VS, direct seeding) and weed control practices including granular herbicide Sunstar 15WG (Ethoxy sutfuron), conventional hand weeding and herbicide Machete 60EC (Butachlor) Significantly influenced the yield and yield centributing attributes during either year of the study Both the Sunstar and Machete application proved their efficacy against the weeds but could not match with hand weeding treatment Minimum weed population m'', dry weed biomass g m" after 30, 60 and 90 DAS and maximum paddy Yletd (5.7 and 8.5 t he") during both the experimental years and its assOCiated components were receded in transplanting method as compared to direct seeding. Similarly, among weed control strategies, the paddy yield, net return of Rs,13, 815 and 27,815 ha''and BCR were the highest in hand weeding, followed by herbiCide application of Machete 60EC, The direct seedmg method could not perform in a good way in terms of low paddy yield and high weed infestation. While in experiment 4, the effect of seeding techniques was significant for most of the agronomic and physiological parameters However, transplanting Hat and parachu1e planting techniques showed the outstanding performance for most of the characters investigated. Maximum net relum of Rs. 12,630 and 15,730 and 6,050 and 14,800 was recorded In transplanting on flat and parachute planting techniques, respectively dunng both the planting seasons Other seeding techniques such as diract seeding on flat, direct seeding on ridges and transplanting on ndges could not excel transplanting on flat and parachute planting in most of the ahributes recorded. On the basis of research findings, it is concluded that conventional transplanting technique on flat with a plant-ta-plant and row-ta-row spaCing of 20 em is most suitable on planting date 20" June with 1 seedling hill". Among weed control practices, hand weeding is most effective, followed by herbicide treatment Machete 60EC Nursery preparation and seedling broadcasting of parachute technology although, a cumbersome job but produced higher paddy yield and nel return per unit area.

        The research methodology represents a scientific feature that highlights its manifestations and its fruits according to the nature and results of the methodology; this shows the intellectual contribution and impact on the advancement of human civilization in the scientific field.  The methodology of Muhaddithin provided an innovative and practical approach about the certainty of narations which they had devised and applied.           The question is: what is the way to document the narrations? To answer this question needs to refer to the books of sciences of Hadith, and when looking at these books shows that they are addressing this issue under different topics.           But the knowledge of narrations in terms of the factors pertaining to certainty is not covered in special sub title, but there are hints scattered in different places in the books of sciences of Hadith. There is still a need to address the issue comprehensively in all aspects relating the factors of certainty, Hence the goal of the research from the next two points 1- Exploration the foundations and factors pertaining to the certainty about the narrations. 2- Highlight the methodological innovation according to Muhaddithin in this regard. The purpose of this article is to provide a comprehensive overview of Methodological Bases and warranting Circumstances for Sunnah Authentication.

Synthesis of Ag I -N-Heterocyclic Carbene and Cyclonickellated Complexes for Chemical and Biological Studies

Metal complexes exhibit a wide variety of functional groups in drug designing and development due their vaious chemical properties, coordination modes, geometries and reactivities. Organonikellated and silver complexes have become attractive tool in the field of catalytic as well as medicinal chemistry. The present project was designed to synthesize new series of silver-N-Heterocyclic carbene (NHC) and cyclonickellated complexes. Various NHC based as well as phosphine/phosphinite based precursors were designed leading to the synthesis of target silver and nickel complexes, respectively. Three series (A-C) of novel mono- and bisimidazolium salts (1a-16a, 1b-12b, 1c-7c) as ligands and their mono, di, tri and polynuclear silver complexes (17a-20a, 13b-20b, 8c-12c) were synthesized. The corresponding silver(I) aducts were afforded by the in situ deprotonation of the NHC based ligands. Some of the NHC salts (7a-12a) of series A were found to be difficult to react with silver due to steric factor (bulky alkyl substituents attached to them), so their silver complexes could not be synthesized. The synthetic approaches of the ligands of series B were controlled by the methyl substituents attached to the backbone of benzimidazole imposing significant impact on the reactivity by the virtue of their aptitude to enhance sigma electron donating ability of ligands. The precursors and silver complexes were well characterized by FTIR, GC-MS, 1H, 13C (one and two dimensional), 31P and 19F NMR, elemental analysis, melting points, ESI-MS and single crystal X-ray crystallographic techniques. Adopting a different protocol of synthesis using excess of reactant, an interesting trinuclear silvercomplex (8c) was synthesized. After successful syntheses, the silver complexes were employed to study their redox potentials by cyclic voltammetry. The quasi reversibility and irreversibility of redox events in the electrochemical study of silver complexes indicated that the reduction event produces unstable decomposed species and oxidation event may be ascribed to decomposed species. Azolium salts and their Ag(I)-NHC complexes were tested in vitro against Bacillus subtillis, Macrococcus brunensis, and Bacillus cereus to study their antibacterial activity and against MDA-MB-231 and HCT116 cells to study their anticancer potential. All compounds were observed to pose potential antibacterial and anticancer activity, however, silver-NHC complexes were found relatively more potent compared to the corresponding NHC precursors (salts). Only few salts were found inactive, while their complexes were observed to be active concluding that the silver imparts greater anticancer potential to the compounds. Being air and moisture sensitive, cyclonickellated complexes could not be utilized for evaluation of their antimicrobial, anticancer or redox potential, however, the attempts were made to study their functionalization behaviour under inert atmosphere. It was observed that the coordination of PR2 moiety into CNi bond is apparent from the initial colour change and shift of 31P NMR and 19F NMR signals but final products of insertion remained difficult to be analyzed as they usually decomposed or appeared NMR silent after workup.In order to understand the feasibility of reaction and to evaluate the properties of product of insertion, further attempts were made to get target complexes via different way by synthesizing phosphine-phosphinite ligands and reacting them with nickel precursor. Appearance of specific signals in NMR spectra of few products provided some evidences of formation of the target products but later the products decomposed and signals disappeared. Thus the products of all reactions were very difficult to identify by NMR either due to paramagnetic nature or decomposition of products and crystallization attempts remained unsuccessful so their structures remained ambiguous as no other technique could help to study them due to their air/moisture sensitivity. On the whole the present project provided useful information for drug designing and chemical transformation studies.
