Edge enhancement is derived from lack of accurate result from edge detection techniques. The image which is captured from long distances carries a lot of noise and blur which causes edge discontinuity. Although some novel algorithms which are based on cellular neural network, fuzzy enhancement and binary morphology have shown accuracy in order to obtain refined edge but still the problem of edge discontinuity arises. Eliminating discontinuity of edge a hybrid technique is proposed based on pixel neighbors pattern analysis PNPA. In the technique Canny operator for initial edge detection, PNPA operation for edge enhancement are performed for remote sensing satellite image successively. The visual and subjective evaluation shows that the proposed PNPA operation can effectively eliminate the influence of edge discontinuity which occurred due to noise and blurr in original captured image, as comparing to existing edge segmenting processes.

One of the main reasons behind reduced cane yield is pathetic method of planting. Planting method and row spacing are the most important yield contributing factors in sugarcane. A field experiment was carried out in order to determine quality and yield of sugarcane in various spatial arrangements. Treatments are 180 cm spaced trenches with triple row strips;180 cm spaced trenches with alternate row strips;120 cm spaced trenches with double row strips and 60 cm spaced furrow with single row. Perusal of data revealed that 3.6%, 13.4%, 15%, 15.3% more cane diameter (cm), cane length (cm), stripped cane yield (t·haˉ1), sugar yield (t·haˉ1) were obtained from 180 cm spaced trenches with triple row strips as compared to conventional planting method i.e. 60 cm spaced furrows. While the number of millable canes mˉ2, polarity %, cane juice purity %, cane juice %, commercial cane sugar % and cane sugar recovery % remained non-significant by different planting techniques.

The present study was designed to evaluate the susceptibility of Culex quinquefasciatuns against malathion in Sargodha district of Pakistan. The activities of detoxifying enzymes i.e., β-esterases, GSTs and monooxygenases were also estimated. Our results revealed 100 percent mortality in insecticide treated groups after 24 hours of exposure. There was no difference in the activities of insecticide detoxifying enzymes between control and treated groups. We concluded from our work that malathion is still effective against C. quinquefasciatuns in the area for control of mosquito population.

Indian mustard (Brassica juncea L.) germplasm consisting 167 accessions including one check cultivar was evaluated for qualitative and quantitative traits. The present study was conducted to investigate genetic diversity and correlation among studied genotypes of B. juncea L. based on agro-morphological at NARC, Islamabad, Pakistan. To investigate the genetic diversity based on morphological characters, data was recorded on 20 quantitative and 12 qualitative traits. The calculated data was analyzed through two complementary methods, i.e. PCA (Principal Component Analysis) and cluster analysis. Among all the studied cultivars, significant diversity was recorded for different agro-morphological characters. Among all the parameters, maximum variance was recorded for pod shattering (427.2) followed by plant height (345.6), days to 100% flowering (336.2) and main raceme length (210.0). Among all the characters, the greatest and highly significant association (0.99) was found between days to maturity 50% and days to maturity 100% followed by correlation (0.86) among days to flowering 50% and days to flowering 100%, correlation value (0.71) was calculated among leaf length and leaf width. Using cluster analysis all the genotypes were divided into five major groups. It was observed that 7 out of 20 principal components with an Eigen value of ≥1.0 calculated for 73.92% of the total diversity observed between 167 accessions of Indian mustard (B. juncea L.). The contribution of first three PCs in the total PCs was 23.25, 12.87 and 11.24, respectively. Among all the investigated accessions two genotypes 26,813 and 26,817 showed great potential for seeds/silique, 1000-seed weight and seed yield/plant, respectively, so these genotypes are recommended for future breeding programs for achieving promising results.

为了研究Co空位对Mn_3CoN化合物磁性质和热膨胀性能的影响,采用固相烧结法制备了名义配比为Mn_3Co_(1-x)N(x=0,0.1,0.2,0.3)的反钙钛矿结构化合物,并研究了该类化合物的晶格、磁转变和热膨胀性能。结果表明:所有的样品均显示出2个磁转变点;随着x的增加,低温磁转变点往高温移动,高温磁转变点往低温移动;同时,所有的样品中都发现了反常热膨胀行为,包括低于270K的低热膨胀和270K附近的负热膨胀;低热膨胀区间的线膨胀系数随着x的增加而呈现出减小的趋势;值得注意的是,当x=0.3时,样品在100~240 K温度区间内显示出近零热膨胀行为,其热膨胀系数α=9.70×10^(-7) K^(-1);Mn_3Co_(1-x)N化合物中的反常热膨胀行为可能是磁体积效应所致。
