GIZA 11 AND GIZA 12; TWO NEW FLAX DUAL PURPOSE TYPE VARIETIES

Sixteen flax genotypes {13 promising lines and 3 check varieties viz., Giza 8 (oil type), Sakha 1 (dual purpose type) and Sakha 3 (fiber type)} were evaluated for straw, seed, oil yields and their related traits under twelve different environments; four locations (Sakha, Etay El-Baroud, Ismailia and Giza Exp. Stations through three successive seasons (2011/12, 2012/13 and 2013/14). These materials were evaluated in a randomized complete blocks design with three replications at the twelve above-mentioned environments. The analysis of variance revealed highly significant differences among genotypes (G), environments (E) and G x E interaction for all studied traits except straw weight per plant, indicating a wide range of variation among genotypes, environments and these genotypes exhibited differential response to environmental conditions. The significant variance due to residual for all characters except both straw weight per plant and oil yield per fad indicated that genotypes differed with respect to their stability suggesting that prediction would be difficult, which means that mean performance alone would not be appropriate. Interaction component of variance (σ2ge) was less than the genotypic variance (σ2g) for all characters, indicating that genotypes differ in their genetic potential for these traits. This was reflected in high heritability and low discrepancy between phenotypic (PCV) and genotypic (GCV) coefficients of variability values for these traits indicating the possibility of using each of long fiber percentage, plant height and technical stem length as selection indices for improving straw weight per plant, as well as, using 1000-seed weight and capsules number per plant as selection indices for improving seed weight per plant. Yield stability (YSi) statistic indicated that S.541-C/3 and S.541-D/10 gave high mean performance and stability for straw, fiber, seed and oil yields per fad in addition to oil percentage, capsules number per plant and 1000-seed weight. Therefore, the two genotypes well be released under the name Giza 11 and Giza 12, respectively. These newly released varieties are of dual purpose type for straw, fiber, seed and oil yield. They may replace the low yielding cultivars Giza 8, Sakha 1 and Sakha 3

Alterations in proteins and amino acids of the Nile cyanobacteria Pseudanabaena limnetica and Anabaena wisconsinense in response to industrial wastewater pollution

The effect of industrial wastewater on the Nile cyanobacteria Pseudanabaena limnetica and Anabaena wisconsinense was investigated. The data showed that P. limnetica was more sensitive to pollution than A. wisconsinense. The treatments with different levels of wastewater exerted pronounced reductions in protein and amino acids content. SDS-PAGE analysis revealed that the cyanobacteria grown in the industrial wastewater showed induction in the synthesis of certain polypeptides and repression of others. The treatments of P. limnetica with wastewater stimulated the appearance of six protein bands with molecular masses of 28, 30, 31, 32, 58 and 97 kDa. The same treatments caused the disappearance of 20, 38 and 56 kDa. The structural protein pattern of the treated A. wisconsinense showed appearance of 16, 30, 170 and 230 kDa and disappearance of 56 kDa. The treatment of the two investigated cyanobacteria with different levels of wastewater stimulated the biosyntheses of different amino acids and inhibited others

Experimental Analysis of Conditions Based Variations of Characteristics and Parameters of Photovoltaic Modules

This paper presents an experimental determination of the main and advanced characteristics of photovoltaic (solar-PV) modules as affected by variations in the solar irradiance and temperature. In addition, the effects of connecting modules in series, and in parallel are inspected. The measured main characteristics are the current/voltage (IV), and power/voltage (PV) relations, while the advanced characteristics include the form factor (FF), shunt resistance (Rsh), series resistance (Rs), characteristic resistance (Rch), and efficiency (). The impacts of the various levels of partial shading on the performance of the modules are also presented. Two identical 10 Wp modules are used in the tests. The sun’s energy is simulated using two lighting sources: One 1 kW halogen floodlight and four 100 W incandescent lamps. These light sources offer spectral which is very close to that of the black body radiation; however, they provide a lower color temperature in comparison with the sun. Therefore, they closely match the requirements of the IEC 60904-9 Edition2 and ASTM E927-10 standards of solar simulators. The electrical load is represented using two wound rheostats of 1200, and 500. The temperature is measured by a remote temperature sensor, while the electrical variables are measured using digital multi-meters. For cost reduction, the solar irradiance is estimated based on the linear relation between the short-circuit current, and the solar irradiance. The results are presented within the main text, and summarized in the conclusions section. It is found that the parameters such as Rs, Rsh, Rch, FF, and  are not constant, but they are highly dependent on the variations in the irradiance, and the temperature. The salient conclusion is that the standard equivalent circuit model of solar-PV modules that includes constant parameters needs to be significantly enhanced by considering the variations of the circuit parameters as affected by the variations in the solar irradiance and temperature.<br
