Determination of Aquifer Characteristics from Geo-electrical Sounding data in parts of Anambra State, Nigeria

Anizoba, D. C. — 2015-06-27T00:00:00-00:00

The execution of water borehole project is quite expensive, there is therefore need for surface resistivity measurements before drilling to gain sufficient knowledge on the subsurface geo-hydrological conditions of an area. In this study, geophysical investigation of groundwater is aimed at delineating the aquiferous units in the central part of Awka by determining their depths, thicknesses, resistivities and the potential borehole depth at various locations within the area employing the technique of Vertical Electric Sounding (VES) using the Schlumberger array. Ten (10) sounding stations were obtained. The data was interpreted using conventional partial curve matching and computer aided iteration techniques. The vertical electrical sounding curve types identified in the study area includes K, H, QH, HK, and QK. The HK-type sounding curves were predominant in the study area. About four to six geo-electric layers comprising the top soil, shaly- sand, sand, dry sand, water saturated sandstone, and shale were delineated with the shale usually occurring as the last layer. Lithologic log for the borehole located near one of the sounding station at Awka revealed that some of the geologic units were either suppressed or merged into a single geo-electric unit probably due to similarities in electrical resistivity. 3-D surface map of the aquifer characteristics were produced, it was observed that the aquifer properties ranges from 0.0262 to 0.7187cm/s, 1.2995-48.0092cm2/s, 139.14-3813.22 Ohm-m, 9,294.55-189,135.71 Ohm-m2, 0.0130-0.4801 Ohm-1 for hydraulic conductivity, transmissivity, resistivity, transverse resistance and longitudinal conductance respectively within the study area.

AL-Juboori, Abbas Fadhil Mohammed Ali — 2015-06-27T00:00:00-00:00

Cloud computing is the result of evolution and adoption of existing technologies and paradigms. The goal of cloud computing is to allow users to take bene?t from all of these technologies, without the need for deep knowledge about or expertise with each one of them. The cloud aims to cut costs, and helps the users focus on their core business instead of being impeded by IT obstacles.Building cloud computing serves educational institutions, such that it will serve the educational and administration staff and students.In our research, web pages site for the educational foundation and the university was designed to spreading the educational concepts specific for the learning of far distance cultures for two types synchronize or unsynchronized by using the cloud to design the students information management systems to monitor the students records from the first day in the course to the last day, which will help the educational staff and the administrator staff to get the right information in a proper time to take a right decision, with high speed and quality.Finally, planning and building a system using cloud computing technique was explained, and how to design it, what we need of requirements to build this system, as well as how to test and implement that system was presented.

Caesarean section: about 147 cases at the Mohamed V Hospital Chefchaouen in northern Morocco

EL Khlifi, Farid — 2015-06-27T00:00:00-00:00

Objective: Determine whether the existence of special clinical situations nursery (origin, gestational age, obesity and age) or fetal (breech presentation, and macrosomia term exceeded), associated with risks must include the completion of a C-section.Patients and methods: cross type prospective study including singleton pregnancies who delivered at the Mohamed V Hospital in Chefchaouen in northern Morocco, from 1 September 2013 to 30 August 2014. The maternal and fetal factors were analyzed.Results: Over the period studied, 305 were studied childbirth which 147 have given birth to a caesarean section. This population was from, about 53% rural, 26% of Chefchaouen Bab Taza 12% and 7.8% of Ouazzane. At significantly higher rates of caesarean section in patients at from Ouazzane (p andlt;0.018). Analysis summit presentation is an interesting univariate prognostic factor acceptability of vaginal Exp (B) = 0.415 [0.244 to 0.708]. As against a presentation above is to the detriment of birth vaginally Exp (B) = 9.946 [1.225 to 80.720]. Three strong predictors of birth by natural means, term gestational age (Exp (B) = Gross 0.378 [0.178 to 0.799] a normal body mass index (Exp (B) = 0.389 [0.157 to 960 ]) and macrosomia (Exp (B) = Gross 0.536 [0.308 to 0.933]). While a term greater than 40 weeks of gestation was associated with a significantly increased risk of caesarean section (Exp (B) = 3.480 Gross [1.432 to 8.459]). Using multivariate models, it has been shown that in a patient from Ouazzane, presents a high risk of cesarean birth regardless of the type of presentation in these same patients but from another Ouazzane that the presentation of any seat remains a protective factor in favor of vaginal delivery (Exp (?)a between 0.14 and 0.46 Summit presentation to the top). But is increasing in If the extended term when the presentation is top type.Discussion and conclusion: There is insufficient current data to systematically carry out a C-section for breech presentation. This is a much debated issue but this work has allowed us to identify a statistical model that should narrow down the choice, but still needs to be validated by a prospective study.

INFLUENCE OF PERFORMANCE APPRAISAL ON JOB PERFORMANCE OF LIBRARY EMPLOYEES IN SELECTED UNIVERSITY LIBRARY AND INFORMATION CENTERS IN SOUTH-WEST NIGERIA

Ikonne, Chinyere Nkechi — 2015-06-27T00:00:00-00:00

This study investigated the influence of performance appraisal on job performance of library employees in selected University library and information centers in South-West Nigeria. The survey research design was used for the study. Study population consisted of 133 library personnel in four university libraries. Sampling was purposive and enumerative as all members of the population were used for the study. Data collected were analyzed using frequency and percentage counts. Findings revealed that library personnel perceived performance appraisal as the routine evaluation of an employees' output; as a management tool aimed at improving the performance of employees; as a technique for determining staff compensation but not a management tool for strengthening superior - subordinate relationship. The study also revealed that performance appraisal could influence job performance as it improves and motivates personnel to work harder. Based on these findings, some recommendations like finding suitable appraisal scheme that will best suit the employees of the library in performing; giving a regular feedback to the employees after an evaluation; and gearing staff performance exercise towards staff productivity and performance were made.

Svahn, Ola — 2015-06-27T00:00:00-00:00

Thermal degradation of antibiotics has been studied for decades in a broad range of disciplines including food production, agriculture and analytical chemistry. Yet, there is a lack of thermal stability data for many antibiotics. Here we systematically investigated the thermal stability of ten commonly prescribed antibiotics applying a laborsaving automated in-house pressurized dynamic flow-through system. The design of the system allowed a fast access to a large number of data at medium to subcritical water temperatures, ranging from 50-250

Aestivation and time dilation in anurans

Sayed Mahmoud, Dr. Med — 2015-06-27T00:00:00-00:00

Aestivating frogs are able to withstand long periods of immobilisation whilst appearing to maintain their muscle mass and contractile performance. The functional capacity of critical muscles is also not compromised upon emergence from aestivation. Years of starvation and immobilisation endured by aestivating anurans has no deleterious effect on their muscles, bones, water content, or stomach and liver integrity, which suggests there is some sort of time dilation at work in aestivating frogs that makes months or years inside their aestivation cocoon pass as days or weeks would when active normally.

Monitoring behavior-based Intrusion Detection System for 6loWPAN networks

RGHIOUI, Anass — 2015-06-27T00:00:00-00:00

Even when 6LoWPAN has an ideal cryptography line defense, it is still necessary to implement an intrusion detection system (IDS) to deal with threats targeting network performance such as DoS attacks. IDS discover and stop most attacks that make changes on the operation of the network. However, few IDS solution has been proposed for 6LoWPAN networks. IDS missions are to monitor and raise an alarm about any possible threats and pass it to the system to restart the keying process for eliminating the attackers. New technique has been proposed recently based on the principle that neighbor nodes have a trend to have the same behavior, so the detection of the malicious node is based on the detection of the abnormal node that has a bad behavior different than it neighbors. The security goal is to provide a monitoring system that will attempt to detect anomalous malicious behavior and to prevent it from harming the network performance basing on the neighbors nodes behavior monitoring.
