A review of observational evidence in favour of a metallicity dependence of WN and WC stars is presented. New near-IR studies of Milky Way, LMC and SMC early-type WN stars are presented, with weaker winds amongst WN stars containing hydrogen. A metallicity dependence is supported for WN stars with hydrogen, with dM/dt ∝ Zα with α ∼ 0.8±0.2 The influence of CNO content upon WN subtypes is discus...

Cetiedil is a potential antisickling agent whose major effect appears to be at the erythrocyte membrane. To test the hypothesis that cetiedil alters cation transport, we studied the effect of the drug in promoting changes in cell water (Wc), cell sodium (Nac), and cell potassium (Kc). Results are quite different depending on the presence or near absence of intracellular ATP. With fresh cells, 1...

Background Insulin resistance (IR) is a major cardiometabolic risk factor in females with polycystic ovary syndrome (PCOS). The euglycemic clamp is the gold standard method to measure IR. However, considering the time and cost that it takes, surrogate markers of IR are now widely used. The current study aimed at evaluating the cutoff points of even less invasive anthropometric and body composit...

In this paper, Cu-based composites were prepared by the powder metallurgy method with spark plasma sintering (SPS) technique using WC (tungsten carbide) particles as reinforcing phase and Cu matrix. The effect of temperature on electrical mechanical properties was investigated, variation in content investigated at optimum temperature. microstructure 5 wt. % WC/Cu different temperatures 850 °C d...

OBJECTIVE To examine the effect of two Chinese liquors with quite different nonalcoholic components on insulin sensitivity, tissue polyunsaturated fatty acids (PUFA), and hepatic lipid metabolism in SD rats. METHODS Thirty-three SD rats were randomized into four groups and maintained in each treatment for 10 weeks: Chinese tea-flavor liquor (TFL, n=9), traditional Chinese liquor (TCL, n=8), e...

Water is mixed with the crude oil to form complex multiphase fluid during extraction process. Some of traditional methods measure relative amount water (known as water-cut or WC) are intrusive, which prone wear and tear. Few other methods, used for WC sensing, either unable cover full range (0-100% require good mixing production be sensed accurately. This paper presents a unique robust design d...

It is generally known that the two most crucial elements of concrete depend on slump value mixture are workability and compressive strength. In addition, retention more delicate than commonly used since it reflects mixture’s durability for usage in civil engineering applications. this study, effect three water-reducer additives was tested concrete’s strength from 1 day to 28 days curing. The me...

We present a catalogue of non-nuclear regions containing Wolf-Rayet stars in the metal-rich spiral galaxy M83 (NGC5236). From a total of 283 candidate regions identified using He ii λ4686 imaging with VLT-FORS2, Multi Object Spectroscopy of 198 regions was carried out, confirming 132 WR sources. From this sub-sample, an exceptional content of ∼1035±300 WR stars is inferred, with N(WC)/N(WN)∼1.2...

the objective of this research is to investigate the effect of four additives including iron slag (is), works debris (wd), fly ash (fa), and lime kiln dust (lkd) on the biochemical properties of biosolids produced at mangere wastewater treatment plant (mwwtp), auckland, new zealand. all these additives are homogenously mixed in the laboratory with biosolids at various percentages with and witho...
