Vitamin A deficiency is prevalent health problem across the poor families of the developing countries. To combat the vitamin A deficiency, development and deployment of PVA biofortified maize hybrids is most suitable solution. Indigenous 150 genotypes were selected and evaluated across autumn and spring seasons. Significant differences were observed in yellow maize genotypes across autumn and spring seasons. Variability was also observed for TCC and PVAC. Yellow maize genotypes were high yielding in spring season relative to autumn season. Genotypes, 15328, 19175, 15069, 15077, 15189, 15258, 24688, 15186, 15100 and 15105 were unanimously declared stable with higher grain yield across autumn and spring seasons. Different genomic SSR loci were used to dissect the genetic variability in different maize inbred lines. Targeted SSR loci were highly polymorphic due to having higher PIC value (0.6733 to 0.7207). Numbers of alleles were varying from 3.714 to 4.286 for Umc1595 and Umc2332 loci respectively. Genetic variability dissection on geographical basis showed that seven populations were not distinctive for PVA linked SSR loci and most of the genetic variance was depicted by among the inbred lines (85%). Yellow maize inbred lines from KPK origin had highest alleles, effective alleles and Shannon information index. UPGMA Clustering and PCoA showed that inbred lines were not distinctively grouped for geographical origin by PVA linked SSR loci. Distinctively selected inbred lines and testers were evaluated for their performance in single cross hybrid combinations. Significant differences were observed among genotypes, lines, testers and line × tester interaction for studied traits. L5, L6 and T1 were having higher GCA effects for YPH, RPC, and FW whereas, L1, L5 and T4 were having higher GCA effects for TCC, PVAC and NPVAC. Among studied crosses, L7×T3, L8×T4, L5×T2, were having higher SCA effects for PVAC whereas, L2×T5, L3×T3, L4×T2, were having higher SCA effects for YPH. L3×T3 has higher SCA effects for YPH, TCC, PVAC and NPVAC. L8×T4 were having SCA effects for PVAC, RPC and FW. L2×T5 were having higher SCA effects for PVAC, YPH, NPVAC and TCC. Most of variability was contributed by L×T interaction. Variance analysis showed that all of the traits were under the control of non-additive gene action. L1×T3, L5×T3, L3×T3, L3×T1 for PVAC, RPC and TCC, whereas, L5×T4, L10×T3, L5×T5, L5×T1, L8×T3 for YPH and FW were having higher mid parent heterosis. L1×T1, L3×T5, L7×T1, L10×T5, L7×T2 and L9×T1 for FW, YPH and PVAC were having highest better parent heterosis. Exotic PVA biofortified maize hybrids were evaluated across different locations for stability analysis. G×L interaction was significant for studied traits. Data were subjected to AMMI and GGE biplot stability analysis across the locations. AMMI and GGE biplots showed that HP1097-11, HP1097-2, HP1097-18 and HP1097-19 were high yielding with stable performance. PCA biplot showed that indigenous and exotic maize hybrids were grouped distinctively for yield and PVAC. Based on yield and PVA contents introduction of HP1097-2, HP1097-18, HP1097-11, HP1097-19 and HP1097-20 is strongly recommended in Pakistan. Exotic PVA biofortified maize hybrids were also subjected to different postharvest sundrying treatments to evaluate the quality losses. Results showed that starch contents were affected negatively in maize grain by direct exposure to sun light. Losses in starch contents resulted in proportional increase of protein and oil contents in PVA biofortified maize hybrids. Significant losses of TCC and PVAC were observed under direct exposure to sun light. Thus, direct sun drying of PVA biofortified maize hybrids was not recommended.

گزشتہ مہینے جناب خلیل الرب صاحب وفات پاگئے، وہ پھولپور (الٰہ آباد) کے رہنے والے تھے، محکمہ تعلیمات میں ملازم تھے، اس سلسلے میں اعظم گڑھ برسوں قیام رہا شبلی منزل برابر تشریف لاتے، اردو سے عشق تھا۔ ادب و تنقید پر چند کتابیں بھی لکھیں، یو پی اردو اکیڈمی اور مسلم یونیورسٹی کورٹ کے ممبر تھے، باغبانی اور چمن آرائی کا عمدہ ذوق تھا، دارالمصنفین کی گولڈن جوبلی کے موقع پر ان ہی نے چمن بندی کی تھی جس کو ڈاکٹر ذاکر حسین صاحب نے بہت پسند کیا تھا اور ان سے گلاب کی بعض قسمیں دہلی منگائی تھیں۔ اﷲ تعالیٰ مغفرت فرمائے۔ آمین!!

Utilization of Fad Distribution in South Buton Waters As a Fishing App by Purse Sein Fishermen in Kadatua District, Selatan Buton Regency

Fish Aggregating Devices (FAD's) have long been used by fishermen in South Buton Regency. This study aims to determine the utilization of FAD distribution as a fishing aid by purse sein vessels in the waters of Kadatua District, South Buton Regency. This study aims to determine the utilization of FAD distribution as a fishing tool by purse sein vessels in Kadatua District, South Buton Regency. Data collection methods include FAD point data taken from GPS (Global Position System) fishermen and dominant catch data from purse sein fishermen. The results of the study obtained data on the distribution of FADs in Kadatua District spread between a distance of 0-12 miles, during the study the coordinates of FADs were obtained as many as 79 coordinate points owned by fishermen in Kadatua District. FADs used by purse sein fishermen to carry out fishing operations have 24 FAD points, which are spread over a distance of 0 – 12 miles. In April the distribution of FADs used as fishing aids by purse sein vessels was at a distance of ± 0 – 12 miles, while in May and June FADs used as fishing aids were at a distance of ± 2 – 12 miles. The dominant fish catch data for purse sein fishermen is 690 kg in April, 525 kg in May and 735 kg in June. The dominant catch during the study was dominated by scad fish (Decapterus spp). The level of effectiveness of the dominant catch of purse sein fishermen is highest at a distance of 4-12 miles with a total catch of 1,070 kg of the total catch of 1,950 kg.

Optimal Homotopy Asymptotic Method to Solution of Partial Differential Equations

Nonlinear Differential equations are of major importance in different fields of science and engineering. For complicated nonlinear problems exact solutions are not available and alternate way is to use numerical methods, Iterative methods or analytical techniques of perturbation. Numerical methods use discretization a have slow rate of convergence. Iterative methods are sensitive to initial conditions and in case of high nonlinearity they do not yield converged results. In perturbation methods small parameter is applied on the equation and hence cannot be applied for high nonlinear problems as they do not have small parameter. One of domain type methods is known as OHAM. This method is free from small parameter assumption and do not need the initial guess. The proposed method provides better accuracy at lower-order of approximations. Moreover the convergence domain can be easily adjusted. In this thesis OHAM is implemented for solution linear and nonlinear tenth order ODEs. Then its effectiveness and generalization is shown to a nonlinear family of PDEs, including Burger, Fisher, Burger’s–Huxley, Burger’s–Fisher, MEW and DGRLW equations. The results of the proposed method are compared with that of DTM, VIM, ADM, HAM and HPM, which reveal that OHAM is effective, simpler, easier and explicit. Apart from application to PDEs, OHAM is applied to couple system of PDEs. The coupled WBK, ALW, MB systems are used as test examples and results are compared with those obtained by HPM. OHAM is implemented to DDEs as well, and solution of MKdV lattice equation is presented for the illustration of proposed technique. The results are compared with HAM and HPM. In all cases the results obtained by OHAM are in close agreement with the exact solution and reveal high accuracy.
