Fingerprint is one of the oldest, reliable and mature biometric technologies and is considered one of the best, cheapest and legitimate proofs of identification. A correlation between physical characteristics like fingerprints and blood group was demonstrated in previous studies. This study was carried out in 2010 on 305 Libyan medical students of Al-Jabal Al-Gharbi, University, Zawia, Libya and were selected randomly having different ABO blood groups, with the objective to a) Study distribution of fingerprint pattern among the subjects having different ABO and Rh blood group b) Correlate any relation between their characters and blood group. The data from the study showed that male: female ratio was 1.2:1. Majority of subjects (48.9%) in this study were of blood group O followed by blood group A (33.1%), B (12.8%) and AB (5.2%). Rh-positive cases constitute about 87.2% of all studied cases. The general distribution of pattern of finger showed high frequency of Loops registering 50.5%; followed by whorls (35.1%) and arches (14.4%). In Rh+ve cases of blood group A and O loops incidences were the highest (52% and 54.3% respectively) then whorls (33.4% and 30.6% respectively), while in blood group B whorls were predominance in both Rh+ve and Rh-ve cases. In all blood groups there were high frequency of loops in thumb, index and little fingers. © 2011 Elsevier Ltd and Faculty of Forensic and Legal Medicine. All rights reserved. Source

The paper presents studies on experimental investigation of beam-to-column joint behaviour in standard and exceptional events situations, This assessment is done to form a picture of the general the behavior of full scale frameworks at both the level of the global behavior of the framework, in terms of its load-displacement characteristic, and of the local behavior of joints in terms of their moment-rotation characteristics, and evaluates details about the interaction of the joint elements and how they work together in a balanced manner. The paper addresses these problems using two types of joints flush and extended end-plate for the evaluation of joint moment-rotation response when exposed to negative and positive moments together.

Cutaneous leishmaniasis (CL) is an endemic parasitic infection in the Mediterranean region, including Libya and its Al-jabal Al-gharbi province. We aimed at studying the occupational relevance as well as other epidemiological aspects of CL. We investigated 140 CL cases who attended at Gharyan outpatient polyclinic during a period of 6 months in 2009. CL infection was clinically diagnosed and confrmed by demonstration of Leishmania parasites on smears from lesions. Our fndings showed that males were more affected than females (P= 0.04), and people above 10-years were more affected than younger ones (P=0.0001). A significant percent of CL cases belonged to Al-Kawasem subprovince (P=0.0001). Farm-related activities were the most frequent occupations among CL cases (P= 0.04). In addition to farm workers, housewives and students are at risk groups since they are engaged at farm activities. Moreover, those who have occupations that require staying outdoors for a part of night, e.g., policemen, are also at risk. Compared to children, adult CL patients had multiple lesions (P= 0.001) that were more prevalent in their upper and lower extremities than the face (P=0.0001). We conclude that CL is a major health problem in Al-jabal Al-gharbi province of Libya. The presence of rodents and sandfies makes it a suitable environment for Leishmania to spread in an endemic epidemiological pattern. Being engaged in farming activities or outdoor occupations increases the risk of infection. Various clinical patterns of CL suggest the presence of more than 1 species of Leishmania at Al-jabal Al-gharbi province. We propose that the 2 species responsible for CL in this area are L. major and L. tropica. Further investigations to identify the leishmanial species responsible for CL at Al-jabal Al-gharbi together with adoption of preventive and control programs are needed. © 2013, Korean Society for Parasitology and Tropical Medicine.

Anti-Corrosion Methods and Materials

Purpose: The purpose of this paper is to present the results of some corrosion inhibition studies of brass in 3N HNO3 by gemini surfactants. Design/methodology/approach: Gemini surfactants namely: N-trimethyl butane-diyl-1,2-ethane-bis-ammonium bromide (BEAB), N-hexane-diyl-1,2-ethane-bis-ammonium bromide (HEAB), N-dodecane-diyl-1,2-ethane-bis-ammonium bromide (DDEAB) and N-hexadecane-diyl-1,2-ethane-bis-ammonium bromide (HDEAB) were synthesized in the laboratory and their influence has been investigated for controlling the dissolution of brass in 3N HNO3. Weight loss, potentiodynamic polarization and electrochemical impedance have been employed for the study. Weight loss experiments were performed as per standard method (ASTM, 1987). Potentiodynamic polarization studies were carried out using EG&G PARC potentiostat/galvanostat (model 173), universal programmer (model 175) and X-Y recorder (model RE 0089) and impedance measurements were carried out with an EG&G PAR (model 5301 A) lock-in-amplifier, using an IBM computer. Findings - The inhibition efficiency for all the gemini surfactants increases with increase in concentrations. The maximum inhibition efficiency of each inhibitor was achieved at 250 ppm concentration. The inhibition efficiency of all the inhibitors decreases on increasing the temperature from 30 to 50°C. The results of potentiodynamic polarization studies revealed that all the compounds were mixed type inhibitors and inhibit the corrosion of brass by blocking the active sites of the metal. The adsorption of the compounds on brass surface in 3N HNO3 has been found to obey the Langmuir adsorption isotherm. Originality/value: The paper provides information regarding corrosion inhibition of brass in 3N HNO3, the mechanism of the inhibition on the basis of molecular structures of the inhibitors, activation energy and free energy of adsorption. © Emerald Group Publishing Limited.

Conventional precoded spatial multiplexing multiple-input multiple-output (MIMO) systems using limited feedback are mainly based on the notion of time invariant channels throughout transmission. Consequ-encely, the precoding matrix can be found during the training symbols and used over the subsequent data symbols. In this paper, a more practical system where the channel varies from one block of symbols to another is considered. In such scenario, the precoding matrix designed at the receiver based on the previous training symbols becomes outdated, which results in significant system performance degradation. In order to avoid this problem, and reduce performance degradation, we propose the use of a Kalman filter linear predictor at the receiver to provide the transmitter with the precoding matrix for the next block of symbols. The performance of this method is assessed using computer simulation, and the obtained results for the proposed channel prediction demonstrate improved bit error rate performance for time-varying Rayleigh fading channels. © 2014 Engineering and Technology Publishing.
