M Ali, K Alam, Y T A Al-Majali, M Kennedy
Over the last few decades, electrostatic precipitators (ESP) have emerged as effective air pollution control devices for treating Coal-fired power plant exhausts. Among the components of the ESP, the discharge electrodes are extremely important in determining the collection efficiency of the ESP. Typically, in wet electrostatic precipitators, the discharge electrodes used must be made of corrosion resistant alloys, which makes them extremely expensive and heavy. Hybrid composite discharge electrodes have the potential to be lightweight and corrosion resistant substitute for traditional metal alloy electrodes used in wet electrostatic precipitators (WESP)...

BACKGROUND/PURPOSE: Although measuring transepidermal water loss (TEWL) is important to assess the barrier function of the stratum corneum (SC), the commercially available instruments are rather expensive. Recently launched Model H4500 employs a closed-chamber system to measure TEWL and is more reasonably priced compared to devices currently in general use. METHODS: To check the reproducibility of the obtained data with H4500, we conducted measurements on the volar forearms of healthy volunteers and compared these data with those measured with Vapometer(®) and Tewameter(®) ...

During a crime, biological material such as blood or vaginal fluid may become smeared on the fingers of the victim or suspect or trapped under their fingernails. The type of trapped fluid is extremely valuable forensic information. Furthermore, if either person touches an object at the crime scene with their 'contaminated' finger then a 'contaminated' finger mark may be deposited. Such marks have great value as they could identify not only who deposited the mark but also who they touched and which part of the body they touched...

BACKGROUND: Pre-operative spine level localization by palpation of anatomical landmarks (ribs, spinous processes) in posterior approaches for surgeries from T4 to L2 is often inaccurate. This can lead to ineffective utilization of procedural time, increased radiation dose, potentially longer skin incision and wrong level surgery. Factors affecting topographical accuracy includes body mass index (BMI) of the patient, congenital or acquired deformity and knowledge of topographical anatomy...

The crystal structures of two title Schiff base derivatives, C15H12N4O·C2H6O (1·EtOH) and C13H13N3O2S (2), were determined at 110 and 100 K, respectively. In the crystal of compound 1·EtOH, the (E)-N'-[(1H-indol-3-yl)methyl-idene]isonicotinohydrazide and ethanol mol-ecules are linked by O-H⋯O, N-H⋯O and N-H⋯N hydrogen bonds, forming a tape structure running along the b-axis direction. The tapes are weakly linked via a C-H⋯N inter-action. In the crystal of compound 2, (E)-N-methyl-2-[1-(2-oxo-2H-chromen-3-yl)ethyl-idene]hydrazinecarbo-thio-amide mol-ecules are linked via N-H⋯O and C-H⋯O hydrogen bonds, forming a helical chain along the b-axis direction...

In 2003, the Haitian Study Group on Kaposi's Sarcoma and Opportunistic Infections (GHESKIO), a nonprofit organization, began administering antiretroviral therapy (ART) to its patients. This practice transformed HIV from a fatal disease to a more manageable chronic condition. However, relatively few studies focus on the experiences of survivors. This study provided a unique opportunity to interview patients who survived at least 10 years after being treated with ART at GHESKIO. The goal of the study was to elicit from patients their perspectives on what enabled them to survive with AIDS...

An acceptable area for collecting DNA reference sample is a part of the forensic DNA analysis development. The aim of this study was to evaluate skin surface cells (SSC) as an alternate source of reference DNA sample. From each volunteer (n = 10), six samples from skin surface areas (forearm and fingertips) and two traditional samples (blood and buccal cells) were collected. Genomic DNA was extracted and quantified then genotyped using standard techniques. The highest DNA concentration of SSC samples was collected using the tape/forearm method of collection (2...

A facile transfer process for transition metal dichalcogenide WS2 flakes is reported and the effect of the underlying substrate on the flake properties is investigated using Raman spectroscopy. The flakes are transferred from their growth substrate using polymethyl methacrylate (PMMA) and a wet etch to allow the user to transfer the flakes to a final substrate using a microscope and micromanipulator combined with semi-transparent Kapton tape. The substrates used range from insulators such as industry standard high-k dielectric HfO2 and "green polymer" parylene-C, to conducting chemical vapor deposition (CVD) grown graphene...

Partition (K) and diffusion (D) coefficients are important to measure for the modelling of skin penetration of chemicals through the stratum corneum (SC). We compared the feasibility of three protocols for the testing of 50 chemicals in our main studies, using three cosmetics-relevant model chemicals with a wide range of logP values. Protocol 1: SC concentration-depth profile using tape-stripping (measures KSC/v and DSC /HSC(2) , where HSC is the SC thickness); Protocol 2A: incubation of isolated SC with chemical (direct measurement of KSC/v only) and Protocol 2B: diffusion through isolated SC mounted on a Franz cell (measures KSC/v and DSC /HSC(2) , and is based on Fick's laws)...
