Organisms in aquatic environments are exposed to a number of pollutants such as pharmaceutical residues. As such, the aim of the present study is to achieve the Lethal Concentration (LC50) of Povidone-iodine (Betadine) for Cyprinus carpio. To do so, the study employs samples, weighing 4±1 [mean±SD] gr, and carries out an experiment in static condition. Based on OECD instructions, after a period...

Background and Aim: There is a gap of information on the effect of time, disinfectant, and storage conditions on the dimensional stability of direct post patterns made of self-cure acrylic resins. This study assessed the effect of Deconex® and wet or dry stor-age conditions on the dimensional stability of post patterns made of Duralay and GC acrylic resins. Materials and Methods: Sixty spe...

objective: the aim of the present study was to evaluate three thawing rates on the post thaw motility, viability and chromatin structure of buffalo semen frozen in 0.5-ml straws. materials and methods: in this experimental study semen was collected with artificial vagina (42˚c) from four buffalo bulls.split pooled ejaculates (n=4) were extended at 37˚c with a bioxcell® extender. semen was coole...

Abstract Sago solid waste is a lignocellulosic material that can be used as raw for making bioethanol. The lignin component of lignocellulose slow saccharification by preventing cellulase enzymes from accessing cellulose. pre-treatment stage the first lignocellulose-to-bioethanol conversion process, and it to lower levels in lignocellulose. Saccharification fermentation are next processes turni...

BACKGROUND AND PURPOSE We evaluated the impact of admission hyperglycemia (HG) on stroke outcome in relation to the timing of reperfusion in patients treated with tissue plasminogen activator (tPA). METHODS We studied 138 consecutive stroke patients with a documented middle cerebral artery (MCA) occlusion treated with intravenous tPA <3 hours of stroke onset. Serum glucose was determined at b...

introduction: laser irradiation has been introduced in endodontic treatment due to its bactericidal effect. the aim of this study is to evaluate the bactericidal efficacy of a 940 nm diode laser alone or in combination with 5% sodium hypochlorite (naocl) against mature biofilms of e. faecalis . methods: sixty-eight (60 for the three groups, 4 for sem and 4 as negative controls) single-rooted hu...

In the fluorescence excitation spectrum of acetaldehyde cooled in a supersonic jet, we performed a full rotational analysis of combination bands 100 140 150 n and 100 140 150 n , n50 – 4 in the system ÃA9– X̃A8. The vibrational frequency of the C–C–O bending mode is determined to be n10 8 5373.163(3) cm. The rotational structures of combination bands 100 140 150 , 100 140 150 , 100 140 150 , and...

cellulose is a raw material which is extensively used in the manufacture of paints, papers, textiles, agricultural products and cosmetics. the waste of sugar beet pulp after titration is a source of cellulose. the current study was carried out to study the possibility of cellulose production from sugar beet pulp waste at titration stage as a 3×3×2 factorial study on the basis of a randomized co...

The tempered martensite lath structure of a 10% Cr martensitic steel after normalizing and tempering at 750 °C was studied. effect reducing the temperature from 770 by 20 on microstructural parameters in shown. Tempering lower provides thinner laths finer M23C6 particles (55 nm) than °C. Such structural changes do not affect creep rupture time 650 applied stresses 180 160 MPa, whereas positive ...
