The purpose of this research was to study a simple technique of screening for drought resistance in sorghum (Sorghum bicolor (L.) Moench). Ten cultivars were evaluated for drought resistance by subjecting seedlings in flats to four successive cycles of water stress in a controlled environment chamber. The cultivars were selected to represent a range of drought resistance. After the fourth cycle of stress cultivars known to have resistance had the highest survival; e.g., 'M.35-1' had a survival of 65% while 'Karkatib' had the lowest survival of 10%. The technique appeared to be a simple and effective method of screening for drought resistance.

The film structure of prepared catalyst was characterized by X-Ray Diffraction spectrum. The physical properties also studied such as: porosity, pores size and surface area. The photocatalytic activity of prepared catalyst was studied by photocatalytic degradation of Neutral red dye by using sun light .In this work the effects of parameters such as amount of catalyst, effect of pH and dye concentration on photocatalytic degradation of dye were studied.

Rabbits are considered induced ovulatory animals, and when artificial insemination (AI) is applied, the ovulation has to be induced by exogenous hormones (GnRH). Different synthetic GnRH analogues (gonadorelin, buserelin, triptorelin, leuprorelin) have been successfully utilized. In addition, some studies have demonstrated that ovulation can be induced successfully in rabbit females by the vaginal absorption of different GnRH analogues, which are included in the seminal plasma, avoiding intramuscular injection. Recently, using hormones in rabbit reproduction technology management becomes unfavorable from the welfare point of view. Bio-stimulation methods are natural and are an alternative to hormonal treatments. These methods include doe-litter separation (DLS), lighting control and male proximity. The temporary separation of the rabbit doe from litters before AI is an alternative approach for...

We aimed to find regional gray matter (GM) volume difference of these symptoms, in AD patients compared to AD control, and investigate possible associations of GM atrophy with cognitive covariant. Study subjects were retrieved from the Alzheimer's Disease Neuroimaging Initiative database. Thirty-five participants are AD control, 27 AD patients with anxiety, 19 with depression and 24 with apathy, ages ≥ 55.1 years. Recruited subjects had an assessment of their clinical and structural MRI data. GM differences and clinical data were analyzed using voxel-based morphometry and ANOVA with Scheffe post hoc test, respectively. We found significant GM volumes differences in the left insula, left parahippocampal, posterior cingulate and the bilateral putamen in the anxiety group. The results also revealed that the right parahippocampal, Brodmann area 38 and the middle frontal gyrus were significant in patients with depression. Significant results were with a p < 0.05, corrected with AlphaSim program for multiple comparisons. The left insula had a strong negative association with Clinical Dementia Rate Sum of Boxes and Alzheimer's Disease Assessment Scale-cognitive subscale-13 items in anxiety and apathy groups. The difference in GM density in the left insula and hippocampus plays a crucial role in depression, anxiety and apathy NPS and outline precise approaches to test these symptoms.

They were analyzed for their physical, chemical composition and minerals content.Results: The acidity (%), total soluble solid, TSS Brix and pH values of tamarinds fruit pulp showed that sample A scored the higher value 28.87%, 42.2 Brix in acidity and TSS, respectively. All proximate analysis parameters determined were significantly different (P≤ 0.05) in the two samples except the ash content. Results showed that tamarind samples contain high amounts of Ca (149.13 – 174.19 mg/100g), in addition to Fe (68.94 – 80.67 mg/100g). The P content of the two samples was very low (3.63 – 9.06 mg/100g). For vinegar production, the fruit pulp was first digested and fermented with Sacch...

Observations in the field cannot be made regularly, nor can the condition be repeated. A laboratory method of testing for drought resistance was needed. To investigate techniques, 10 cultivars of sorghum, Sorghum bicolor (L.) Moench, were planted in washed sand in plastic plots in a growth chamber. Five plants in each pot were fed a nutrient solution for 3 weeks. When they were harvested, wet root weight, root length, root volume, and root/shoot ratio were determined. The purpose of this study was to evaluate the root characteristics among 10 sorghum cultivars known to vary for drought resistance. Significant varietal differences for all characters were found. In general the most drought‐resistant cultivars had heavier root weight, greater root volume, and higher root/shoot ratios. This technique shows promise for identifying drought‐resistant lines, but it involved a considerable amount of...
