To improve agronomic and quality in bread wheat, this experiment was performed in 2015/16 and 2016/17 seasons at Sakha Agricultural Research Station, Egypt to study performance of ten bread wheat (Triticum aestivum L.) genotypes (Giza 171, Sakha 95, Gemmeiza 12, Shandweel 1, Sids 12, Sids 14, Misr 3, Line 1, Line 2 and Line 3) and their forty-five F 1 crosses were evaluated for sixteen agronomic and grain quality characters. The mean squares for genotypes, parents, crosses, parents vs. crosses, general and specific combining ability were significant for most studied characters. The ratio of general and specific combining ability was more than unity for all characters and both additive and non-additive gene effects were important in controlling the studied characters with more importance for additive effects. The best performance was detected in Sakha 95, Sids 14 and Shandweel 1 for grain yield plant -1 , all parents except for Sids 12 and Giza 171 and Shandweel 1 for yellow rust, Line 1 for stem rust and Gemmeiza 12 and Sids 12 for dry gluten. The best combiners were Sakha 95, Sids 14, Giza 171 and Misr 3 for grain yield plant -1 and Giza 171, Sakha 95, Gemmeiza 12 and Shandweel 1 for wet and dry gluten. Grain yield plant -1 had positive significant correlation with grain filling rate, plant height, number of spikes plant -1 and kernel weight. The correlation of dry gluten was significant and positive with wet gluten and negative with hydration capacity percentage. Path coefficient analysis showed that the highest positive direct effect on grain yield plant -1 was obtained by grain filling period, wet gluten, days to maturity and days to heading. On the other hand, the highest negative direct effect was detected by dry gluten, hydration capacity percentage and days to anthesis. The highest positive direct effect on dry gluten was obtained by wet gluten, grain filling rate and days to maturity. Meanwhile, the highest negative direct effect on dry gluten was obtained by grain yield plant -1 , hydration capacity percentage and days to anthesis. Using stepwise regression, days to heading, grain filling period and rate, kernel weight, yellow rust resistance and electrical conductivity had justified the maximum of grain yield plant -1 changes. Number of kernels spike -1 , wet gluten and hydration capacity percentage had justified the maximum of dry gluten changes. Giza 171 × Misr 3, Line 1 × Line 3, Sids 12 × Misr 3, Giza 171 × Line 2, Sakha 95 × Shandweel 1, Sakha 95 × Gemmeiza 12 and Shandweel 1 × Misr 3 crosses had high yield potentiality and resistance to yellow rust and moderately susceptible to stem rust, consequently these crosses will be favorable in wheat breeding programs. Sakha 95 × Gemmeiza 12 and Sids 12 × Misr 3 were the best crosses for dry gluten and will be promising in breeding for wheat grain quality.

The present investigation aimed to evaluate some Egyptian cotton cultivars i.e.: Giza 86, Giza 94, Giza 87, Giza 88, Giza 92, Giza 93 and Giza 96 under three different locations in Lower Egypt (Delta) during the two successive growing seasons of 2015 and 2016 for yield, seed quality and viability characters. Randomized complete block design with three replications was used at each location. Significant differences for cultivars and locations for all studied characters, except free fatty acid and acid value. The effects of the growing years, interactions between (genotype x seasons), (location x season) and the second order interaction were significant on most studied characters, Also the effect of the interaction between (genotype x locations) was significant for all studied characters, except for seed cotton yield and lint percentage. Giza 94 and Giza 92 surpassed in seed cotton yield, boll weight, lint percentage and seed index. The cultivar Giza 92 gave the highest oil % and germination, while, Giza 96 produced the highest radical length, shoot length and seedling dry weight, while. Giza 88 surpassed all studied cultivars in protein %.Positive significant correlations were found between seed cotton yield and both boll weight and seed index, lint percentage and each (boll weight, seed volume and seed coat), boll weight and seed coat %, seed index and both (seed volume and seedling dry weight), free fatty acid and acid value, protein % and seed coat %, seed volume and seedling dry weight, germination % and both (shoot length and seedling dry weight), shoot length and seedling dry weight.

An Electrocardiogram (ECG) signal is a recording of the electrical activity of heart. It considered as an important source of vital diagnostic information. ECG signal is exposed to different types of noise. These noises change the nature of the ECG signal and provide difficulties on its analysis.The one long Least Mean Squares (LMS) adaptive filter is an algorithm used to reduce the noise effect on the ECG signal. This algorithm is widely used in adaptive filter applications due to its simplicity and low computational complexity, but it suffers from low convergence speed.This paper proposes to improve the one long LMS adaptive filter convergence speed using the multiple sub-adaptive filters proposed algorithm where simulations show that at MSE of 0.04 the required number of iterations are saved by about 4.3*10 4 times compared to the one long LMS adaptive filter. Also comparison between them is performed in terms of Signal to Noise Ratio (SNR) against the step size (µ). It is found that the proposed algorithm provides improvement in the SNR by 5 dB at µ=o.2.The ECG samples are recorded from MIT-BIH database and an additive white Gaussian noise (AWGN) is added to the signal to examine the proposed technique and 2011a Mat lab platform is used to simulate these results.

ABSTRACT. The effects of crude thymus extract on the immune response and protection against challenge with virulent infectious bursal disease virus (IBDV) were studied in one-day-old chick. Oral administration of thymus extract (1 ml/kg) markedly and significantly increased the total protein, albumin, globulin, Tri-iodothyronine (T3), Thyroxine (T4) and the body weight gain in one-day-old chick. In addition, it increased the total lymphocytic count over four weeks after administration. Although vaccination also increased total protein, globulin, T4 and the total lymphocytic count but it significantly decreased the body weight gain of the chick and administration of thymus extract, before, during or after vaccination markedly improved the vaccination effectiveness with significant elevation of the globulin level and body weight gain of the chick. It also prevented the decrease in the relative weights of bursa, spleen and thyroid gland which commonly prevailed during vaccination. Chicken administered thymus extract and vaccinated with infectious bursal disease (IBD) vaccine showed 100 % protection against challenge with IBDV. Meanwhile the vaccinated non-thymus treated group exhibited 80% protection against IBDV challenge. These results indicate a potentiating effect of thymus extract on the immune system in baby chick. These findings are supported by ELISA results that showed a marked increase in antibody titers in thymus treated groups. Additionally, microscopical examination of the bursa and the existent lymphoid hyperplasia in thymus treated groups but not vaccinated group support our findings.-KEY WORDS: chicken, IBDV, immunopharmacology, thymus extract.

Background: Recently the growth of online learning programs has been driven by the progress of the internet and the information technology that improved the education. Due to advancement of the latest technology, online learning has arisen as a substitute complement to traditional teaching and learning. Objective(s):To determine factors affecting satisfaction of Sohag university students with online learning. Methods: Strachota's Online Satisfaction Survey was applied on 782 students from faculty of medicine, pharmacy and education to assess the satisfaction of students with online learning. It included five main parameters (student-content interaction, student-instructor interaction, studentstudent interaction, student-technology interaction, and general satisfaction). Results: Half of the studied students (50.3%) were not satisfied with online learning as a continuous method for education. Males were more satisfied (59.5%) than females (45%). Students living in urban areas (53%) were more satisfied than those of rural areas (45.8%) and students of faculty of medicine were more satisfied (54.4%) than faculties of pharmacy and education (40% & 48.6% respectively). The availability of computers and internet was significantly affecting the satisfaction of students with all parameters. Conclusion: Half of the studied students were not satisfied with online learning as a continuous method for education. The factors affecting the satisfaction of students with online learning were availability of computers and internet, male gender and urban residence.
