Techset Com For the first time, 3D printed metal-pipe rectangular waveguides (MPRWGs) have been demonstrated in the WM-380 (500–750 GHz) and WM-250 (750 GHz–1.1 THz) waveguide bands. The ultra-high spatial resolution offered by the new RECILS additive manufacturing technology enables the precision fabrication of these prototype MPRWGs at such high frequencies. This enabling technology avoids th...
Extended Abstract Introduction: Lavandula angustifolia L. is one of the most important plants belonging to Lamiaceae which has abundant use in traditional and pharmacological medicine. Lavender seed dormancy is one of the problems in producing seedlings which increases seed consumption. In this regard, an experiment was carried out to investigate different treatments for seed dormancy eliminat...
Genetic analysis of wood chemical composition is often limited by the cost and throughput of direct analytical methods. The speed and low cost of Fourier transform near infrared (FT-NIR) overcomes many of these limitations, but it is an indirect method relying on calibration models that are typically developed and validated with small sample sets. In this study, we used >1500 young greenhouse g...
دوغ به علت ph پایین تمایل زیادی به فساد میکروبی به ویژه در دمای محیط نشان می دهد. این تحقیق به منظور تعیین اثر دو باکتریوسین نیسین و ناتامایسین بر ویژگی های فیزیکو- شیمیایی، میکروبیولوژیکی، حسی و الگوی پروتئولیز دوغ انجام گرفت. نیسین در سه سطح ppm150، 500 و 750 و ناتامایسین در دو سطح ppm 5 و 10 در سه تکرار به دوغ اضافه شد و در دماهای°c 4 و 21 نگهداری گردید. پس از گذشت 1، 15، 30، 45، 60، 75 و ...
BACKGROUND This study evaluated the efficacy of an epidural single dose of neostigmine combined with sufentanil to provide selective and balanced analgesia at the beginning of labor. METHODS After informed consent, 125 healthy parturients were randomly allocated to receive, after a test dose, a single injection of either epidural sufentanil 20 micrograms (minimal analgesic dose) or 10 microgr...
Pregnant Sprague-Dawley rats received 50, 250, and 500 mg/kg/day diisononyl phthalate (DiNP) from GD 12 to 19 via corn oil gavage to study the dose response for effects on fetal male rat sexual development as well as metabolite disposition in the dam and fetus. Monoisononyl phthalate (MiNP), mono(carboxy-isooctyl) phthalate (MCiOP), mono(hydroxyl-isononyl) phthalate (MHiNP), mono(oxo-isononyl) ...
Objective: The present study was conducted to investigate the hepatoprotective activity of hydro-ethanolic fruit extract of Rosa canina (R. canina) against carbon tetrachloride (CCl4)-induced hepatotoxicity in rats. Methods: Male Wistar albino rats were randomly divided into six groups of 8 animals of each, including control, toxic (CCl4), R. canina 250, 500, and 750 mg/kg + CCl4 and R. canina ...
PURPOSE To evaluate the association between baseline angle width and laser peripheral iridotomy (LPI)-induced opening of the anterior chamber angle. METHODS Anterior segment optical coherence tomography images captured before and after LPI were analyzed to determine the angle opening distance at 250 μm (AOD250), 500 μm (AOD500), and 750 μm (AOD750) from the scleral spur; trabecular-iris space...
Rhizophora mangle is an abundant plant in mangroves and tannic acid is a polyphenol produced by the secondary metabolism of plants. The aim of the study was to evaluate the embryotoxic and embriostatic effects of the aqueous extract of R. mangle and synthetic tannic acid on eggs and larvae of Aedes aegypti. A. aegypti eggs were exposed in duplicate at concentrations of 250, 500, 750 and 1000 µg...
The effect of different doses of sulphadimidine (250, 500, 750 and 1000 mg) on acetylation capacity in 10 normal individuals was investigated in a randomized cross-over study design. The subjects were initially phenotyped with an oral dose of 750 mg of sulphadimidine. Four weeks later, each subject was assigned four different doses of sulphadimidine. The acetylator phenotype was classified for ...
