مُوصوف ایک علمی گھرانے سے تعلق رکھتے ہیں۔ دینی علوم کے حوالے سے ان کے بزرگوں کی خدمات اظہر من الشمس ہیں ۔اِن کی کتاب ــ ’’ نگارشاتِ راشد‘‘ ایک علمی خزانہ ہے اِس میں طلباء و طالبات کے لیے متعدد مضامین شامل کی گئی ہیں۔ جو اپنی نظیرآپ ہیں حافظ محمد اکرم راشدؔ نے دیگر کتب اور مضامین سے خوشہ چینی کی بجائے فی البدیہہ مواد پیش کرنے کی مساعی جمیلہ کی ہے ۔ اِ ن کی تحریر میں چاشنی اور ندرت ہے۔ اِن کے مضامین جو’’ نگارشاتِ راشد ‘‘کے نام سے زیورِ طباعت سے مرصعّ ومزیّن ہو رہے ہیں عام قاری کے لیے بالعموم اور طلباء و طالبات کے لیے بالخصوص ممدو معاون ثابت ہوں گے۔ ادارہ کے مقابلہ جات ہوں یا ضلعی اور ڈویژن لیول کے مقابلہ جات ’’ نگارشاتِ راشد‘‘ میں شامل شدہ مضامین کفایت کریں گے ۔ یہ طلباء کے لیے نعمت مترقبہ سے کم نہ ہے ۔ موصوف کا ادبی دنیا میں ایک نام ہے اِ ن کو دیکھ کر متقدمین ادباء کی یاد تازہ ہو جاتی ہے ۔ دورانِ ملازمت بھی ادبی پروگرام کے حوالے سے محکمہ تعلیم میں اِن کی تحریریں محو گردش رہی ہیں ۔ اور انعام و اکرام کی حقدار گردانی گئی ہیں۔
اللہ تعالیٰ اِن کو مزید ایسے شاہ پارے پیش کرنے کی توفیق عطا فرمائے ۔

The study investigated school business competencies for improved administrative effectiveness in Public Secondary School in Rivers State. Three research questions and two null hypotheses were formulated to guide the study. The population of the study was 286 principals in all the public secondary schools in Rivers State. A sample of 166 through a stratified random technique was determined using the Taro Yamane formula. The instrument of the study was a self design instrument captioned “School Business Management Competencies Questionnaire (SBMCQ) and Principal Administrative Effectiveness (PAE) with the reliability coefficients of 0.77 and 0.84 respectively which was determined through the Cronbach alpha statistics. Mean scores and standard deviation was used to answer the research questions while Pearson Product Moment Correlation Coefficient was sued to test the hypothesis. It was discovered that the highest kind of business available in the public school is related to cafeteria / canteen services and that also to a high extent, resourcefulness as a business management competency improves administrative effectiveness in public secondary schools in Rivers State. It concluded that for the school administrators to manage the school business effective (administrative effectiveness), they must possess the core competence of resourcefulness, conceptual thinking and administrative organisation. It was recommended among others that the principal should have a comprehensive understanding of the school complex nature and also think critically at both abstract and concrete level to harmonize a rather multifaceted business challenges in the school and proffer realistic solutions.
Research was conducted on two important groups of nematodes plant parasitic nematodes (RKNs) and insect parasitic nematodes (entomopathogenic nematodes). Eggplants (Solanum melongena L.) are the most seriously affected by Meloidogyne incognita. Entomopathogenic nematodes i.e. Steinernema glaseri, S. asiaticum, Heterohabditis indica and H. bacteriophora were evaluated at different time of application against M. incognita for invasion, development and reproduction of M. incognita. In a life cycle study, S. asiaticum and H. bacteriophora were proved more effective in influencing the life cycle of RKNs at all application times than S. glaseri and H. indica. However application of entomopathogenic nematodes before application of M. incognita proved more effective than with and after the application of root knot nematodes. S. asiaticum and H. bacteriophora delayed penetration of nematode juveniles (J2) into roots of brinjal. Cells and toxins of and Xenorhabdus spp. and Photorhabdus spp. proved nematoxic to M. incognita. Higher concentrations of bacterial cells suspensions and toxins were more effective in suppression of hatching of eggs and immobilization of juveniles than the lower concentrations. Percentage inhibition of eggs and juvenile’s immobilization of M. incognita increased with increase in concentration. At concentration of 4x10 7 cells/ml, Xenorhabdus spp. and Photorhabdus spp. cell suspensions completely prevented egg hatching of M. incognita at 48 hrs exposure time. Bacterial cell suspensions and bacterial toxins equally inhibited egg hatching and immobilized juveniles. Bacterial cell suspensions and toxins of Xenorhabdus spp. and Photorhabdus spp. caused more than 90% immobilization of juveniles. The persistence effectiveness of bacterial cell suspensions and toxins in soil were evaluated up to 7, 14 and 21 days against M. incognita and determined that Xenorhabdus spp. and Photorhabdus spp. were effective in suppressing number of galls, number of females, egg masses and reproduction factors after 7 days of application followed by 14, 21 days of application. The efficacy of bacteria and toxins decreased in the soil over long period of time. These bacteria and their metabolites can be stored in vitro on room temperature up to the period of 5 months. Protective and curative effects of Xenorhabdus spp. and Photorhabdus spp. and their toxins on root-knot nematodes were also studied on nematode development parameter, number of females and reproduction factors. All treatments proved effective as comparedto the control. Protective effect of Xenorhabdus spp. and Photorhabdus spp. and their toxins at standard concentrations were more effective in controlling the number of females and reproduction factor of root knot nematodes than their curative effect. Compatibility and the combined action of bacteria (Xenorhabdus spp. and Photorhabdus spp.) and toxins with bio-products (abamectin, emamectin and azadirachtin) against M. incognita were also evaluated. The results of the study showed that the combined use of bacterial cell suspensions and abamectin significantly reduced the population of M. incognita and have synergistic effect with each other.
