In this study, some mechanical properties of borided and unborided four steels were investigated. Boronizing of steels was performed by powder pack method at 1210 K for 4 h. The hardness of borides, boride layer thickness and room temperature tensile properties were measured and it was observed that hardness and tensile properties strongly depend on chemical composition of steels. In addition, ...

The adrenomimetic drugs mimic the effects of adrenergic sympathetic nerve stimulation on sympathetic effectors; these drugs are also referred to as sympathomimetic agents. The adrenergic transmitter norepinephrine and the adrenal medullary hormone epinephrine also are included under this broad heading. The adrenomimetic drugs are an important group of therapeutic agents that can be used to main...

Asmussen-Kroese [1] Monte Carlo estimators of P (Sn > u) and P (SN > u) are known to work well in rare event settings when Sn is the sum of n i.i.d. heavy-tailed random variables, and N is a non-negative integer-valued random variable independent of the Xi. In this paper we show how to improve the Asmussen-Kroese estimators of both probabilities when the Xi are non-negative. We also apply our i...

We have constructed Envismo (energy-visualization-mobility), a prototype of a real-time energy-monitoring platform that pairs common mobile Internet devices (Nokia N810 internet tablets) with cheap, readily available environmental sensors and a webbased datastore tied to an existing energy-monitoring network. This allows for the collection of real-time fine-grained environmental and energy usag...

The effects of a hepaticoactivator, diisopropyl 1, 3-dithiol-2-ylidene malonate (NKK-105), on motoricity and EEG were observed int he rat, mouse, cat and man. NKK-105 suppressed the effects of ethanol (1,000-3,000 mg/kg, p.o., in mice and rats), e.g. the blood alcohol concentration of NKK-105 treated subjects was significantly lower than that of untreated controls. NKK-105, in 100-300 mg/kg p.o...

We investigated the estrogenic activity of various environmental pollutants (xenobiotics), in particular the xenoestrogen o,p-DDT, and compared their effects with those of endogenous estrogens, phytoestrogens, and mycoestrogens on estrogen receptor binding capacity, induction of estrogen end products, and activation of cell proliferation in estrogen-sensitive human breast cancer cells in monola...

The endocannabinoid system consists of cannabinoid CB1 and CB2 receptors, of endogenous agonists for these receptors known as ‘endocannabinoids’, and of processes responsible for endocannabinoid biosynthesis, cellular uptake and metabolism. There is strong evidence first, that this system up-regulates in certain disorders as indicated by an increased release of endocannabinoids onto their recep...
