A wireless body sensor network (WBSN), is a network of sensors deployed on a person's body, usually for health care monitoring. Since the sensors collect personal medical data, security and privacy are important components in BSN. At the same time, the collected data has to readily available in the event of an emergency. In this paper, we present a new secure WBSN architecture for a BSN.

The big growth of the Arabic internet content in the last years has raised up the need for an effective stemming techniques for Arabic language. Arabic stemming algorithms can be ranked, according to three category, as root-based approach (ex. Khoja); stem-based approach (ex. Larkey); and statistical approach (ex. N-Garm). However, no stemming of this language is perfect: The existing stemmers have a low efficiency. In this paper, we introduce a new stemming technique for Arabic words that also solve the problem of the plural form of irregular nouns in Arabic language, which called broken plural. The proposed stem extractor provides very accurate results in comparisons with other algorithms.Consequently the search effectiveness improved.

Many chronic health conditions have been linked to alcohol consumption, as well as excess morbidity, mortality and an increased financial burden on the National Health Service (NHS). The British HIV Association (BHIVA) recommends that HIV patients be asked about alcohol due to its effect on adherence to antiretroviral therapy. National Institute of Health and Clinical Excellence (NICE) guidelines recommend screening for alcohol use disorders in patients attending genitourinary medicine (GUM) clinics. In this study we looked at the use of a screening tool for alcohol use disorders in HIV patients in a metropolitan city. We assessed HIV patients over a 6‐month period for alcohol use disorders using the AUDIT‐C questionnaire. Patients with a score >4 were identified as higher risk and provided with brief advice about alcohol and offered written information and support. Demographic data was collected along with hepatitis B and C status, information on sexually transmitted infection (STI) testing and diagnosis. 352 patients were reviewed with a mean age of 41. 297 (84.4%) patients were male, 235 (66.8%) were white British and 251 (71.3%) were men who have sex with men (MSM). 277 (78.7%) patients were on antiretroviral therapy with 254 (91.7%) of these having an undetectable viral load. Alcohol use disorders were assessed using the AUDIT‐C score in 332 (94.3%) patients with no patient declining assessment. 166 (50%) patients had an AUDIT‐C score >4 signifying higher risk. Alcohol advice was provided to 161 (97%) of these patients and a Drink Smart guide offering advice on alcohol self help offered to 103 (64%) patients and accepted by 45 (43.7%). An opportunistic STI screen was offered to 258 (73.3%) patients on that visit in line with best practice guidelines and was accepted by 83 (32.2%). 25 infections were found in 20 patients, of which 13 (65%) had AUDIT‐C scores >4. There were 8 active hepatitis C co‐infected patients of which 3 had an AUDIT‐C score >4 and 12 chronic hepatitis B co‐infected patients with 3 having an AUDIT‐C score >4. Our results show that screening for alcohol use disorders using the AUDIT‐C questionnaire has high acceptability among HIV patients; however the data is biased to Caucasian MSM. Alcohol use has been shown to exacerbate liver damage in patients with chronic hepatitis, increase the likelihood of STI acquisition and compromise immunity. It is therefore important to screen for and quantify alcohol use as part of routine HIV clinical practice.

Important autocrine/paracrine functions for the adenine nucleotides have been proposed in several tissues. We addressed the possibility that extracellular ATP would modulate/mediate hypoxia-induced adventitial fibroblast growth. Acute hypoxia (3% O 2 , 10–60 min) ...

The genus Solanum includes about 1400 species.1) Solanum nigrum is an important medicinal plant and con-tains solasodine, a steroidal glycoalkaloid, which is consid-ered as a potential alternative to diosgenin for commercial synthesis of various steroidal drugs.2) Solasodine ...

Titanium has an excellent mechanical properties, low density and bio-compatibility. Titanium foams are attractive for structural and biomedical applications. Because of this properties and applications we have tried to produce titanium foam using titanium alloy (TiAl6V4). In this paper, the slurry method was selected to produce titanium foams, in which the sintering process was the most critical part. Foams will be given to consider the properties of titanium foam after sintering process.

Cholesterol biosensor has been fabricated by covalently coupling cholesterol oxidase (ChOx) via glutar-aldehyde onto electrochemically prepared polyaniline film in presence of TritonX-100 [4-(1,1,3,3-tetramethylbutyl) phenyl polyethylene glycol], a non-ionic ...

This paper describes series results of experiments conducted at Paka Thermal Power Station, which is located near the East Coast of Peninsular Malaysia. More than 12 samples of typical cap-and-pin glass insulators that are commonly installed on electrical power ...

The contamination severity on the insulator surface can be expressed by equivalent salt deposit density (ESDD). The value of ESDD varies with the distance of the insulator from the source of contaminants. Normally, the main sources of contaminants affecting insulators are coming from the coastal regions, industrial areas and also deserts. The values of ESDD tend to decrease with increasing distance from the seacoast. In this paper, a relationship between the ESDD and the distance of the insulator from the source of contaminants has ...

The study of polluted insulator flashover mechanism very important for electric power transmission reliability, efficiency and serviceability. In this paper, a new mathematical model based on Ayrton arc voltage gradient equation, which takes account of total resistance of the polluted insulator rather than the pollution resistance value has been proposed. The expression of total resistance of the insulator is also derived. The value of critical flashover voltage (CFV) obtained from the model is in good agreement with the ...

For design purposes, the specific knowledge about the creepage distance of the insulator for the contaminated environment is important. This can be done easily if the mathematical relationship between the creepage distance and Salt Deposit Density (SDD) is known. In this paper, a relationship between the creepage distance of the insulator and SDD has been proposed using the Dimensional Analysis technique. The results calculated from the proposed expression are compared with other results and found to be in close ...

ABSTRACT In the title compound, C14H14N2O5S2·H2O, the six-membered ring fused to the β-lactam unit has a twisted conformation. Weak intramolecular N—H...S and C—H...O interactions occur. Intermolecular C—H...S, N—H...O, C—H...O and O—H...O hydrogen-bonding interactions stabilize the crystal structure, forming a three-dimensional network. Weak C—H...π interactions are also present.
