A Web-Based Interface For A High Performance Computing System

High performance computing systems (HPCS) target to execute software whether this software is a simple or complicated one. Most of HPCS should have an interface to enable software owners to upload their files to be installed by the HPCS administrator. The interface should be extensible to work together in the future with the other remaining parts of the complete system. Also it has to be divided into phases in order to make development easier and also to make those components reusable. It is the best option to make the software a platform independent one. To achieve that, J2EE (Java 2 Enterprise Edition) should be chosen to implement this interface and also free licensed and open source software have to be chosen such as Tomcat Jakarta server, MySQL to be used in the development phases. All of the previous recommendations are applied in this research prototype. On top of that, the interface prototype has been tested on local environment and has achieved the expected results. This report passes through all phases to have a proper web interface to be used for a HPCS

This paper presents an empirical research that realizes a previous research of a conceptual breast-cancer e-portal model with Arabic content. The paper starts with briefing the previous research, after that, it highlights the gaps need to be bridged and the problems need to be solved. A real development of an e-portal prototype is done for achieving the research goal. This e-portal prototype has applied the conceptual model of the previous research

A framework for loosely coupled components to automate municipal services (FLCCAMS)

Unifying and computerizing the procedures of municipal operations and maintenance is of great importance to municipalities as well as to ministries of local governments. On top of that, enhancing municipal e-services in terms of efficiency, quality, reusability, distribution and interoperability of these services; is a goal for most of municipalities.  Municipalities need to unify and computerize the procedures of maintenance and operations for their assets. This will eliminate the difficulties to prioritize the maintenance tasks; to let every task takes its turn fairly. In addition, this will speed up performing such maintenance and operation tasks, and will decrease the bugs appear after the maintenance is done. Therefore, the objective of this research work is to define, design and evaluate a conceptual framework for loosely coupled components to automate municipal services as well as unifying and computerizing maintenance and operations in local governments. The scope of this research covers roads and public buildings as the most important parts of municipal assets

Determination of serum chloride ion concentration in pregnant women from Minjibir local government area, Kano State Nigeria

Serum chloride ion level in blood samples of pregnant women attending ante-natal care clinic in Minjibir was investigated. The mean and standard deviation of the ion in the samples is 100.51± 4.89mmol/L. The distribution is skewed towards high frequency of low concentrations and could be attributed to electrolyte disturbance in some of these women. This disturbance may be due to vomitting, low fluid intake, drugs and malnutrition.Keywords: Chloride ion, pregnant women, ante-nata

Determination of Some Essential Metals in Selected Medicinal Plants

Medicinal plants are sources of different essential metals that have different biological activities including those useful in the treatment of human diseases. Among the indigenous medicinal plants used as phytomedicines for the treatment of many diseases in Kano State are Annona squamosa, Psidium guajava, Anacardium occidentale, Ficussycomorus and Pomegranate. The aim of this study was to determine the levels of essential metals present in the herb tissues (leaf and stem) samples obtained from Kwarin Gogau garden, airport road, Kano State. The plant samples were collected, pretreated and digested by wet digestion method and analyzed using Micro Plasma Atomic Emission Spectrophotometer (MPAES). The results obtained in this study showed that extracts of the medicinal herbs investigated contained essential metals. The mean concentrations range for essential metals were: Zn (0.109-0.658mg/kg), Cu (0.026-0.079 mg/kg), K (1.846 -11.669 mg/kg), Mn (0.039-1.269 mg/kg), Fe (0.019-0.107mg/kg), Ni (0.054-0.144 mg/kg). Comparing the results obtained with the permissible limits set by WHO for consumed medicinal herbs, it was concluded that the essential metals present in the herbs were below permissible limits. Also, there was no statistically significant difference between the plant tissues samples analyzed for Zn, Cu, K, Mn, Fe, and Ni (P>0.05). &nbsp

Predicting the minimum liquid surface tension activity of pseudomonads expressing biosurfactants

Bacteria produce a variety of biosurfactants capable of significantly reducing liquid (aqueous) surface tension (γ) with a range of biological roles and biotechnological uses. In order to determine the lowest achievable surface tension (γMin), we tested a diverse collection of Pseudomonas-like isolates from contaminated soil and activated sludge, and identified those expressing biosurfactants by drop-collapse assay. Liquid surface tension reducing ability was quantitatively determined by tensiometry, with 57 isolates found to significantly lower culture supernatant surface tensions to 24.5 – 49.1 mN m−1. Differences in biosurfactant behaviour determined by foaming, emulsion and oil-displacement assays, was also observed amongst isolates producing surface tensions of 25 – 27 mN m−1, suggesting that a range of structurally-diverse biosurfactants were being expressed. Individual distribution identification (IDI) analysis was used to identify the theoretical probability distribution that best fitted the surface tension data, which predicted a γMin of 24.24 mN m−1. This was in agreement with predictions based on earlier work of published mixed–bacterial spp. data, suggesting a fundamental limit to the ability of bacterial biosurfactants to reduce surface tensions in aqueous systems. This implies a biological restriction on the synthesis and export of these agents or a physical-chemical restriction on their functioning once produced

The therapeutic aspects of the endocannabinoid system (ECS) for cancer and their development: from nature to laboratory

The endocannabinoid system (ECS) is a group of neuromodulatory lipids and their receptors, which are widely distributed in mammalian tissues. ECS regulates various cardiovascular, nervous, and immune system functions inside cells. In recent years, there has been a growing body of evidence for the use of synthetic and natural cannabinoids as potential anticancer agents. For instance, the CB1 and CB2 receptors are assumed to play an important role inside the endocannabinoid system. These receptors are abundantly expressed in the brain and fatty tissue of the human body. Despite recent developments in molecular biology, there is still a lack of knowledge about the distribution of CB1 and CB2 receptors in the human kidney and their role in kidney cancer. To address this gap, we explore and demonstrate the role of the endocannabinoid system in renal cell carcinoma (RCC). In this brief overview, we elucidate the therapeutic aspects of the endocannabinoid system for various cancers and explain how this system can be used for treating kidney cancer. Overall, this review provides new insights into cannabinoids' mechanisms of action in both in vivo and in vitro models, and focuses on recent discoveries in the field
