Protein Electrophoresis and DNA in Herbs Produced from Irradiated Ambrosia maritima Seeds Grown under Soil Salinity and Their Resistance to Insect
O.S. Hussein
American Journal of Plant Physiology , 2012,
Abstract: Damsisa (Ambrosia maritima L.) is one of the wild plants present in Egypt and different African countries of the Nile Valley. It considered as potential source of molluscicides for treatment of infected sites. In this study, DNA amplifications technique and protein electrophoresis were used for the evaluation of response of Damsisa herbs to gamma rays (γ-rays), soil salinity and their interaction on alleviation of salt stress. This study also examined the effect of herb as bio-resistant for insect infestation in Phaseolus beans. Protein electrophoresis revealed that the number of protein bands separated from plants grown in saline soil not changed either grown from irradiated or un-irradiated seeds except 40 Gray (Gy) dose. Meanwhile, it was observed that mixing Damsisa herb with infested Phaseolus beans reduced insect ability to lays eggs or complete life cycle. Also, it was found that herbs produced from irradiated seeds and grown in normal or in saline soil were more effective in destruction of Callosobruchus maculatus insect and decreased the loss from infested beans.

Italian Journal of Animal Science , 2013, DOI: 10.4081/ijas.2013.e35
Abstract: The current study was conducted to identify the influence of short-term (five days) high stocking density (SD) on broilers' welfare by assessing several thermophysiological parameters in 32 birds of 43 days of age Ross male broiler chickens. Based on broiler's body weight, broilers were randomly allotted into two SD rates; control (26.5 kg/m2) or high (45.0 kg/m2). It appears evident that placing broilers at high SD as 45.0 kg/m2 had manifested noticeable impacts on their thermophysiological responses. This conclusion was demonstrated by the existence of results of the current study showed a major displacements in broilers' homeothermic status, high SD broilers experienced pronounced elevations of their body temperatures as well as head, body and shank surface temperatures over the control SD broilers. Additionally, this was further emphasized by the noticeable displacements of body internal, external and total thermal gradients as well as heat loss index of high SD broilers compared to the control broilers. Based on the presented evidences, short-term high SD markedly increased broilers stress and jeopardize their welfare. Measuring broilers' thermophysiological responses under different rates of SD can be adapted to assess their welfare.

American Journal of Plant Physiology , 2012,
Abstract: This study was carried out at the National Center for Radiation Research and Technology during two successive seasons, of 2007/2008 and 2008/2009, respectively in pots 30 cm in diameter. The aim of this experiment was to study the response of damsisa (Ambrosia maritima L.) seeds that exposed to different doses of radiation (0, 20, 40, 80 Gy) after planting in soils contain mixtures of salts. The dose rate was 0.89 and 0.87 rad sec-1. The salts used were NaCl, CaCl2 and MgSO4 in ratio 2:2:1 with concentrations 2000, 4000 and 6000 ppm. Irradiated and un- irradiated seeds were sown in, sand-loamy, soil with mixture of salts. Also, a group of irradiated and un-irradiated seeds were sown in normal soils without salt and serve as a control, all pots irrigated with tap water until field capacity. It was observed that saline condition decreased ambrosin, protein and amino acids trend, in damsisa shoots. While, the results obtained refer to increasing proline concentration separated as a result of uses ?-rays and salinity treatments. The extreme sensitivity of the metabolic processes of proline synthesis and degradation themselves may be of benefit by regulating metabolic processes which adversely affected by stress. So, it was concluded that ?-rays improve plant growth and increase its chemical components under saline stress condition.

Italian Journal of Animal Science , 2013, DOI: 10.4081/ijas.2013.e11
Abstract: The current study was performed to investigate the influence of different stocking density rates on the performance, thermophysiological measurements as well as blood parameters of 0 to 30 d of age female Ross broiler. A total of 96 chicks were randomly distributed in a randomized complete block design among 12 cages. Three stocking density rates were applied; low (28.0 kg/m2), medium (37.0 kg/m2) and high (40.0 kg/m2). Results revealed that cumulative body weight gain (BWG) and feed intake (FI) were influenced (P<0.01) by the rate of stocking density, while no effect (P>0.05) were observed for broilers mortality-corrected feed conversion ratio (FCR). Higher BWG (P<0.01) and FI (P<0.05) were reported for low and medium density rates broilers in comparison to the high density rate broilers. Overall means of body temperature as well as head, neck, wing, body and shank surface temperatures have displayed (P<0.05) higher values in medium and high density rates broilers compared to the low density rate broilers. Furthermore, increasing the stocking density from 28 to 40 kg/m2 induced a state of hemodilution in higher density rate broilers, which might explain the noticeable decrease in packed cell volume (PCV). Meanwhile, an increase in serum aspartate aminotransferase (AST) was observed in the higher density group, which might indicate hepatocellular injures. It can be concluded that increasing the stocking density rate from 28 to 40 kg of BW/m2 had evident impingement effects on the performance of broiler chicken and could jeopardize their welfare.
Effectiveness of Base Plate Thickness Design Criteria in Steel Columns
O.S. Abejide
Research Journal of Applied Sciences , 2012,
Abstract: Steel column base plates are one of the most fundamental parts of a steel structure, yet the design of base plates is commonly not given the attention that it should. This result in base plate details that are expensive, difficult to fabricate and may even contribute to the hazards of the steel erection process by not providing stability for erection load applied to the column(s). The effective area method recommended in BS5950 has been used to study the effectiveness of base plate thickness under various loading conditions with due comparison to AISC provisions. Results indicate that although it is a semi-empirical method, it is more reliable than the empirical method recommended in BS5950; also the approach offers more economy and can be used for all column sections.

Multiple Reflections in Crystals: Natural and Faraday Optical Activity
Kushnir O.S.
Ukrainian Journal of Physical Optics , 2004,
Abstract: A previous analysis of the multiple reflections (MR) of light in crystals is extended to description of particular cases of natural and magnetooptic Faraday optical activity. The differences in manifestations of the MR in the latter effects are discussed and compared with the experimental results. In particular, the MR do not affect the optical rotation related to the natural gyration in case of a rigorously normal light incid-ence. The modifications of the transmittance fit-function of the known polarimetric HAUP technique imposed by the MR are specified. It is shown that the MR in crystals should produce a kind of spurious dichroism.
