In this work, scaling tendency and amount of precipitation of barium sulfate (BaSO4) were determined; the process is depending on temperature, pressure and mixing ratio of injection and formation of waters. Results showed that BaSO4 precipitation is largely dependent on mixing ratio. Temperature and pressure had no influence on BaSO4 precipitation. Different sca...

We used three heterogeneous parental cultures of LSC-AXC rat prostate cancer cells: LSC-AXC-C/0, cells maintained on culture medium; LSC-AXC-D/0, cells maintained on culture me dium containing 10~7 M 5<*-dihydrotestosterone; and LSC-AXCT/0, cells maintained on culture medium containing 10~7 M tes tosterone, to isolate clonally derived cell lines. Eleven of 15 clonal cell lines were tumorigenic ...

As this paper was a very close version of “Investigating task difficulty: learners’ and teachers’ perceptions” by Dr. Parvaneh Tavakoli (published in “International Journal of Applied Linguistics”, Vol. 19, No. 1) in terms of content, research design, analytic framework and research findings without appropriately referencing resources used or obtaining author's consent, the paper wa...

This study was conducted to evaluate the effects of dietary forage type and concentrate-to-forage ratio (CTFR) on CH4 emissions from dairy cows in China using the SF6 tracer method. Rumen fluid concentrations of NH4-N and VFA, rumen fluid pH, and daily milk yield were measured as well. The dietary regimens included: corn stalks (dry corn stalks after corn harvest) as the forage source at CTFR o...

 Background: In many studies, chemicals and natural materials were tested to reduce the harmful effects of radiation. It is known that Famotidine and vitamin C reduce DNA damage.Objective: The aim of this study was to evaluate the radioprotective effect of vitamin C, Cimetidine and Famotidine on gamma-radiation-induced damage on mouse bone marrow. Methods: Six-to-seven week male NMRI mice (28...

Treatment with recombinant interleukin 2 and lymphokine-activated killer cells (rIL-2/LAK) has produced a clinical antitumor effect in preliminary human trials. The cytokines -y-interferon (Il'V-y), tumor necrosis factor a (TNF-a), and tumor necrosis factor 0 (TNF-/S, lymphotoxin) have potent in vitro antitumor activity and some clinical toxicities similar to interleukin 2 (IL-2)/LAK. This stud...

Sediment rating curves, which are fitted relationships between river discharge (Q) and suspended-sediment concentration (C), are commonly used to assess patterns and trends in river water quality. In many of these studies, it is assumed that rating curves have a power-law form (i.e. C= aQ, where a and b are fitted parameters). Two fundamental questions about the utility of these techniques are ...
