Pepper plants growth, yield, photosynthetic pigments, and total phenols as affected by foliar application of potassium under different salinity irrigation water  [PDF]
M. M. Hussein, S. Y. El-Faham, A. K. Alva
Agricultural Sciences (AS) , 2012, DOI: 10.4236/as.2012.32028
Abstract: Irrigation with high salinity water influences plant growth, production of photosynthetic pigments and total phenols, leading to reduction in crop yield and quality. The objective of this study was to investigate the effects of potassium (K) foliar application in mitigating the negative effects of salt stress on pepper plants. A greenhouse experiment was conducted to investigate the effects of foliar application of potassium (K) on pepper plants grown with different salinity water irrigation (3000 and 6000 ppm as compared to tap water with salinity level of 300 ppm). Irrigation using high salinity water decreased plant height, biomass production, and fruit yield as compared to those of the plants irrigated by tap water. Photosynthetic pigments and total phenols increased in the former as compared to those of the latter plants. The most serious affect was for the plants under highest salinity irrigation (6000 ppm) as compared to that of the plants under moderate salinity irrigation (3000 ppm). Foliar application of potassium mono phosphate (KMP) at 200ppm concentration increased the plant growth, biomass production, and fruit yield. Chlorophyll_a content and total phenols increased significantly with foliar application of 100 ppm KMP. Further increase in foliar KMP concentration to 200 ppm had no significant benefits on photosynthetic pigments and total phenols content. This study demonstrated that foliar application of KMP, to some extent, mitigated the negative effects of high salinity water irrigation on pepper plant growth and fruit yield.

Abstract: The purpose of this study was to estimate a point prevalence of depression and anxiety disorders among Sudanese peri-natal women attending ant-natal and postnatal clinics in the capital city of Sudan. Simultaneously, to examine the associated risks factors. Participants were 945 peri-natal women in two main women antenatal and post natal clinics in the Capital City of Sudan screened consecutively. They were divided into two groups. The first group was of, Four Hundreds eighty (480) women in their third trimester, and the second group consisted of Four Hundreds Sixty Five (465) women in the first 10 week of postnatal period. All participants were screened, using Beck Depression Inventory (BDI), Hospital Anxiety and Depression scale (HADS), and Personal information Questionnaire (PIQ) for collecting socio-demographic, personal, medical, social and family history data. Routine urine and blood results were recorded. Results: 59% of prenatal and 46% of postnatal women suffered from high levels of distress in the form of mixed anxiety and depressive symptoms. However, only 20.9% of peri-natal women suffered of moderate to severe depression. Over 90% of the depressed women were not formally diagnosed or received psychiatric help. Poor marital relationship, physical co-morbidity, positive family history and past psychiatric history of depression were the main significant risk factors associated with perinatal depression and anxiety. Conclusion: Contrary to the commonly held views that perinatal women are mainly plighted with depression as the main mental illness, this study confirms initial findings that, anxiety disorder is far more prevalent and more distressing to this vulnerable group. Moreover, psychiatric morbidities in both prenatal and postnatal periods attract high prevalence rates in low income countries. Maternal health policies in low income countries must incorporate routine screening for mental health status, basic support and interventions for mental illnesses in perinatal women. Depression and emotional disorders in perinatal women should be seen as important public health priority.

Abstract: This paper aims to turn complex groundwater data into comprehensible information by indexing the different factors numerically comparative to the standards of World Health Organization (WHO) to produce Water Quality Index (WQI). Water Quality Index (WQI) has been used to assess groundwater quality and Geographic Information Systems (GIS) has been used to create maps representing the spatial distribution of groundwater categories in Assiut governorate, Egypt. Water Quality Index has been computed by Un-weighted Arithmetic Water Quality Index (WQIUA) method and applied on 796 wells over eight years from 2006 to 2013. The results showed that WQIUA values for drinking purposes were high and most of them reached higher or close to 100, which indicated that the groundwater was polluted and unsafe for drinking. On the other hand, the quality index of groundwater for irrigation purposes in most of the study area ranges between 55.78 and 78.38 (poor and very poor category); this means that groundwater is moderately polluted and rather suitable for irrigation.

Journal of Modern Physics (JMP) , 2017, DOI: 10.4236/jmp.2017.812115
Abstract: Study of nucleons charge radii and electromagnetic form factors are expected to provide valuable information about the distribution of electric charge within the fundamental particles in nucleon’s inner structure. In the recent years, dramatic progress has been made in the understanding of the nucleon structure and the precision of its partonic content, due to the vast theoretical progress, and the availability of new high precision measurements. Here in this article, we present a simple model for the charge structure of the nucleons and the most available sets of the structure functions to calculate the mean square charge radius N2> for both protons and neutrons. Our results are consistent with the modern understanding of the nucleons as well as recent experimental data. We discuss the origin of the sign <rN2> for both proton and neutron.

Abstract: Background and objective: Foeniculum vulgare-Mill (Umlliferae), is widely used in the Arabian Peninsula for treating various human and animal diseases. There is need to insure the safety of this plant as a remedy that could be used for a long time. This study aimed to determine the LD50 of the aerial parts of Foeniculum vulgare in mice, as well as to investigate its toxic pathological effects. Methodology: A total of eighty (80) albino mice of both sexes, weighing 25 - 30 g, were used in the present study. Ten (10) mice were used for the determination of LD50 of Foeniculum vulgare in mice. Fifty (50) mice were used in the acute toxicity, and twenty (20) mice were used to study the subacute toxicity of the aerial parts of Foeniculum vulgare juice. Results: the present results revealed that the LD50 of Foeniculum vulgare juice in mice was 9.772 mg/kg/body weight (BW). On the other hand, mice received 0.9 mg/kg/BW of Foeniculum vulgare juice intraperitoneally showed slightly closed eyes intermittent convulsions itching of the nose and increased respiratory rate and abdominal movements. Histopathological examination of the liver showed hepatocytic degeneration and necrosis, congestion with perivascular mononuclear cell infiltrations and peribiliary mononuclear cell aggregations. Whereas the spleen of mice showed depletion of lymphocytes and mononuclear as well as multinuclear cells. The duodenum showed sub-epithelial congested blood vessels, numerous areas of lymphocytic infiltrations and vascular and hydropic degeneration of epithelial cells lining the duodenal Brunner’s glands. Moreover, the kidney showed degenerated tubular epithelial cells, congestion with excess of mononuclear cells, necrotic and desquamated epithelial cells of the proximal convoluted tubules. The lung of mice showed congestion, emphysema with variable degrees of mononuclear cell infiltrations and peribronchial congested blood capillaries and mononuclear cell infiltration. Conclusion: It could be concluded that Foeniculum vulgare juice is toxic to mice when administered in a dose of 9.772 mg/kg/BW. However, the recommended dose for treatment could be less than 0.98 ml/kg BW. (1/10 of the LD50) of Foeniculum vulgare juice.

Abstract: Sweet basil (Ocimum basilicum L.) project that is being conducted at the National Oilseed Processing Research Institute (NOPRI) aims at exploiting the genetic diversity and associated phenotypic variation in the investigated basil germplasm and evaluating key factors such as variety, plant ontogeny and plant parts that affect yield, chemical constituents, aroma and flavor of essential oils. This paper discussed the variability inessential oils content and chemical constituents of the aerial plant parts of the basil. An open-air pot experiment was carried out using three accessions provided by Agricultural Research Corporation-Genetic Resources Unit, Sudan. The essential oils were hydro distilled from the aerial parts, flowers, leaves, stems, using Clevenger apparatus. The chemical constituents of the essential oils were determined by Gas Chromatography-Mass Spectrometry (GC-MS). As the hydro distillation yielded no oil from the stem, we present only the results for leaves and flowers. The results revealed that the essential oil content varied with a range of 0.29% to 0.33% for flowers and 0.32% to 0.48% for leaves. As usual, the content of essential oils was higher in leaves than in flowers. The Silate-Egyptian accession had the lowest essential oil content obtained from leaves and flowers. However, South Darfur accession from Sudan had the highest oil content but did not significantly differ from Kennana accession. Several oil components were identified based upon comparison of their mass spectral data with those of reference compounds published in literature or stored in a computer library. The combined GC-MS analysis showed that methyl eugenol was the major constituent of the essential oil of Kennana accession. While the major constituent of essential oil of South-Darfur and Silate-Egyptian accessions were germacrene and linalool, respectively.

Abstract: Battery management systems (BMS) must estimate the state-of-charge (SOC) of the battery accurately to prolong its lifetime and ensure a reliable operation. Since batteries have a wide range of applications, the SOC estimation requirements and methods vary from an application to another. This paper compares two SOC estimation methods, namely extended Kalman filters (EKF) and artificial neural networks (ANN). EKF is a nonlinear optimal estimator that is used to estimate the inner state of a nonlinear dynamic system using a state-space model. On the other hand, ANN is a mathematical model that consists of interconnected artificial neurons inspired by biological neural networks and is used to predict the output of a dynamic system based on some historical data of that system. A pulse-discharge test was performed on a commercial lithium-ion (Li-ion) battery cell in order to collect data to evaluate those methods. Results are presented and compared.
