This paper investigated the electrodeposition of sulfur on polycrystalline platinum from sulfide polluted brine. Anodic polarization, potentiostatic and electrochemical impedance spectroscopy （EIS） techniques were performed. The slope of Warburg straight line in Nyquiest plot of the EIS spectra performed at 0.0 V indicates diffusion control mechanism of the electrodeposition process. At 0.5 V the Rp （determined from EIS measurements） increased rapidly with time indicating more sulfur deposition and more passivation of platinum surface. Samples subjected to potentiostatic experiments at 0.4, 0.9 and 1.0 V were investigated under Scanning Electron Microscope （SEM）. SEM images reveal the deposition of sulfur on the sample surfaces. The degree of sulfur deposit coverage and its morphology depend on both the potential and time of deposition.

Background: Women with polycystic ovary syndrome (PCOS) are at higher risk of developing endometrial hyperplasia (EH). This study determined the prevalence of EH among women with infertility due to PCOS and assessed the predictive value of endometrial thickness (ET) measurement by trans-vaginal scan (TVS). Study Type & Population: This was a prospective study on infertile women with and without PCOS in which clinical data, hormonal profile, ET and endometrial biopsy (EB) for histopathological examination were collected. Methods: Thirty-seven women with PCOS and 23 women without PCOS presenting with infertility and/or abnormal uterine bleeding underwent TVS, hysteroscopy, laparoscopy and EB. Results: The overall prevalence of EH was 23.3 % while in PCOS group: 18.3 %. The mean ET (14.8 mm) was significantly higher in patients with EH (t = -2.74, P value = 0.009). The lower value of ET among women with EH was 10 mm. A cut-off point of 9.5 mm was set. An ET of >9.5 mm had 92.9% sensitivity and 51.85% specificity for the presence of EH. Women with ET ≥ 9.5 mm were 1.28 times more at risk of EH than women with ET 9.5 mm. Women with oligomenorrhea and irregular cycles were 5.5 and 13.7 times more at risk of EH compared to those with regular cycles, respectively. ET was positively correlated with insulin resistance (r = 0.439, P = 0.007). Conclusion: ET ≥ 9.5 mm predicts EH in infertile women with PCOS, with a high degree of sensitivity and a moderate degree of specificity. In PCOS patients with oligomenorrhea or irregular cycles, the risk of EH is higher than women with regular cycles.

This study was carried out in the northern Khartoum (Bahry Locality) with the aim of knowing the role of agricultural extension in developing the awareness of the farmer to the danger of residual effect of pesticides (vegetable farmers). The social survey method was used to conduct this study;100 vegetable farmers were selected randomly. The data collected through questionnaires, observation, and interviews for primary data, previously concerned, and reference documents were used to collect secondary data. Data collected were analyzed using the statistical packages for social science (SPSS). The study yielded some useful results, the most important of which are: the presence of respondents who obtain their information about pesticides from merchants, the absence of a guide provider in their area, and the absence of any seminars or lectures on the use of pesticides, or programs. For example, radio and television programs were presented but protective clothing was not used. This study is based on the researcher's advocate for the following: intensifying agricultural extension and employee visits to the agricultural field, in addition to intensifying educational evidence for consumers regarding pesticides and providing preliminary data on pesticides and how to deal with them and increase them. Educate farmers about the safe use of pesticides and identify the risks and damages that pesticides cause to humans.

The karyotype of Caspian goby was studied, which has been identified as Caspian bighead goby-Neogobius gorlap before. The results of cytogenetic analyses have shown that the diploid set of goby varies from 38 to 40 chromosomes, which is different from bighead goby （2n = 43-46）. We assumed that Caspian goby has independence as a species.
