The aim of this work is to develop a preconcentration procedure of Cd(2+), Zn(2+) and Cu(2+) in environmental waters using olive pomace (OP) prior to their determination by flame atomic absorption spectrometry (FAAS). Raw OP as preconcentrating sorbent was found to have low permeability towards the passed water samples and thus long time was needed. Even reducing the vacuum pressure caused cart...

Abstract The multi-walled carbon nanotubes (MWCNTs) and the poly(acrylonitrile-co-butadiene-co-styrene) (ABS) granulates are dispersed in acetone separately using a magnetic stirrer followed by ultrasonication. Further, both solutions were mixed with stirring Neat-ABS film, 0.25 wt%, 0.5 wt% 1 of MWCNT-ABS nanocomposite films average thickness 140 µm fabricated solution molding petri dish, room...

PURPOSE Ankaferd Blood Stopper (ABS) is an herbal extract attained from 5 different plants. It has the therapeutic potential to be used for the management of external hemorrhage and controlling gastrointestinal bleedings. To date, the safety of ABS for intraperitoneal usage is not clear. In this study, we investigated the effectiveness and safety of using intraperitoneal ABS in an experimental ...

OBJECTIVE To assess the prevalence of autoantibodies (Abs) to tryptophan hydroxylase (TPH) and aromatic l-amino acid decarboxylase (AADC) in patients with different autoimmune diseases and to analyse their respective epitopes. DESIGN TPH and AADC Abs were measured in an immunoprecipitation assay using (35)S-labelled full-length and fragments of TPH and AADC. METHODS Patients with different ...

OBJECTIVES To assess the knowledge, attitude, and practice of antibiotics (ABs) use and misuse among adults living in Riyadh, Saudi Arabia. Methods: In this cross-sectional study, a self-administered questionnaire was distributed to participants from  March 2016 to January 2017 in the outpatient department of King Khalid University Hospital and Dental Hospital, King Saud University, Riyadh, Sau...

A new hybrid fabrication technique was introduced to manufacture composite laminates made of glass fiber, carbon and acrylonitrile butadiene styrene (ABS) as the matrix. The process utilized two different techniques: fused deposition modeling hot press molding. were produced using five layers fibers form fiber-reinforced composites (GF/ABS) fiber (GF/CF/ABS), with three fibers. fabricated subje...

background: iodine brachytherapy sources with low photon energies have been widely used in treating cancerous tumors. dosimetric parameters of brachytherapy sources should be determined according to aapm tg-43u1 recommendations before clinical use. monte carlo codes are reliable tools in calculation of these parameters for brachytherapy sources. materials and methods: dosimetric parameters (dos...
