ڈاکٹر اعجاز حسین ؍ ڈاکٹر مسیح الزماں
گزشتہ مہینہ میں ڈاکٹر اعجاز حسین سابق صدر شعبہ اردو الہ آباد یونیورسٹی کا انتقال حرکت قلب بند ہوجانے سے مظفرپور میں ہوگیا، جہاں وہ ممتحن بن کر گئے ہوئے تھے، ان کی میت الہ آباد لائی گئی، اپنی ملازمت سے سبکدوش ہونے کے بعد بھی لکھنے پڑھنے کا شغل جاری رکھا تھا، اہم اور مفید کتابوں کے مصنف تھے، جن میں مختصر تاریخ ادب اردو اور نئے ادبی رجحانات وغیرہ زیادہ مقبول ہوئیں، اپنے شاگردوں میں بہت مقبول رہے، ان کی وفات سے اردو ادب ایک بہت ہی لائق مصنف اور خدمت گزار سے محروم ہوگیا، ان سے کچھ ہی روز پہلے ڈاکٹر مسیح الزماں ریڈیو شعبہ اردو الہ آباد یونیورسٹی کی بھی وفات اچانک ہوگئی، اردو کی مرثیہ نگاری ان کا خاص موضوع تھا، ان کی عمر وفا کرتی تو اس صنف میں ان کا ادبی کارنامہ بڑا قابل قدر ہوتا، وہ پروفیسر مسعود حسن رضوی سابق صدر شعبہ اردو لکھنؤ یونیورسٹی کے داماد تھے، جن کے لئے اس کبرسنی میں یہ سانحہ بڑا ہی جانکاہ ہوگا۔
دعا ہے کہ خدا اردو ادب کے ان دونوں خدمت گزاروں کو غریق رحمت کرے، آمین ثم آمین۔ (صباح الدین عبدالرحمن، مارچ ۱۹۷۵ء)
This study aims to calculate the allowance for losses by applying Gaussian Process regression to estimate future claims. Modeling is done on motor vehicle insurance data. The data used in this study are historical data on PT XYZ's motor vehicle insurance business line during 2017 and 2019 (January 2017 to December 2019). Data analysis will be carried out on the 2017 - 2019 data to obtain an estimate of the claim reserves in the following year, namely 2018 - 2020. This study uses the Chain Ladder method which is the most popular loss reserving method in theory and practice. The estimation results show that the Gaussian Process Regression method is very flexible and can be applied without much adjustment. These results were also compared with the Chain Ladder method. Estimated claim reserves for PT XYZ's motor vehicle business line using the chain-ladder method, the company must provide funds for 2017 of 8,997,979,222 IDR in 2018 16,194,503,605 IDR in 2019 amounting to Rp. 1,719,764,520 for backup. Meanwhile, by using the Bayessian Gaussian Process method, the company must provide funds for 2017 of 9,060,965,077 IDR in 2018 amounting to 16,307,865,130 IDR, and in 2019 1,731,802,871 IDR for backup. The more conservative Bayessian Gaussian Process method. Motor vehicle insurance data has a short development time (claims occur) so that it is included in the short-tail type of business.
Indian mustard (Brassica juncea L.) is a member of the Brassicaceae family that is now becoming a global crop because of its drought tolerance, high oil content, short growing season and the ability to grow on low quality soils. The present study was aimed to reduce the viscosity of Brassica juncea oil by altering the fatty acid profile, via developing efficient and simple Agrobacterium mediated based tissue culture and floral dip methods of plant transfermation. For optimization of regeneration protocol, cotyledon explants of the Brassica juncea CV- Raya Anmol were cultured on MS medium supplemented with different concentrations of 6-Benzylaminopurine (BAP), (2, 4, 6, 8, and 10 μM) alone and in combination with 1μM of Gibberellic acid (GA3) and Naphthaleneacetic acid (NAA) separately. Maximum calli production (87%) was observed on MS medium containing 4 μM BAP only. The highest shoot induction efficiency (92%) was observed on medium supplemented with BAP (4 μM) and NAA (1 μM). For rooting, Indole-3-acetic acid (IAA) (6μM) and Kinetin (Kin) (1μM) was found as the best combination. A binary vector containing the EaDAcT (E.alatus diacylglycerol acetyltransferase) gene under the transcriptional control of a glycinin promoter and with a basta selection marker, was introduced into A. tumefaciens strain GV3101 via electroporation. An efficient tissue culture and In planta transformation was developed for B. juncea. In tissue culture transformation, cotyledon explants were used while for floral dip, plants at early stage of flowering with and without vacuum desiccator were used. The basta resistant putative transgenic plants were selected and further confirmed by PCR. The vacuum infiltration was found more efficient (0.85%) as compared to the normal floral dip method (0.15%).The developed transgenic B. juncea seeds showed altered TAG fatty acid composition with enhanced level of oleic acid (from 41% to 63%) and reduced eurcic acid level (from 13.7% to 2.53%), which is an ideal composition of fatty acids in oil to be used as biodisel. The developed protocols could be used to accumulate unusual acTAG in B. juncea seed, providing a direct way of biodiesel production from plant oil. Such results will be useful for the development of B. juncea as an alternative source of energy.
