It is difficult to imagine modern science, industry, and economics without mass measurements in a wide range: from few tenths of milligram up hundreds or even thousands tons. So, Ukraine, this case, not an exception. National medicine, other fields activity increasingly feel the need for reliable traceable results range more than 1 kg. Considering this, national standard unit 2 kg 20 was establ...

In this study, Fe-Cu-Pumice (Fe-Cu-P) composite was prepared to attempt it for UV/Fenton-like treatment of biologically treated textile wastewater by means COD and color removal. SEM-EDX analysis showed that Fe-Cu-P contained Fe Cu at 3.5% each one. More than 95% (RES-436, RES-525, RES-620) removal could be achieved using 3 g/L in the Fenton-like process. The absorbances Abs-254 nm Abs-280 incr...

T he electrocardiogram shown in Figure 1 was read by the computer as arm-lead reversal. Th e computer reading went on to say that no further analysis would be attempted. Th is clearly is a programming mistake because the precordial leads make the diagnosis. Although we would estimate that 95% of electrocardiograms with negative P, QRS, and T waves in lead I are due to armlead reversal, a small ...

Norepinephrine (NE) activates isolated coronary conduit arteries by stimulating Ca2+ uptake into the smooth muscle cells. Blockade of Ca2+ influx by removal of Ca2+ from the bathing medium or addition of 10 mM LaCl3 prevents the NE-induced contraction in the dog coronary artery but still allows NE to induce a rapid transient contraction in the rabbit aorta. Under these conditions, NE stimulates...

Interacting agents in finance represent a behavioral, agent-based approach in which financial markets are viewed as complex adaptive systems consisting of many boundedly rational agents interacting through simple heterogeneous investment strategies, constantly adapting their behavior in response to new information, strategy performance and through social interactions. An interacting agent syste...

1. The heat losses and energy and nitrogen balances of thirty-six individually-housed, entire male pigs (initial body-weight 18-30 kg) were measured over 7 d periods, when they were fed on rations containing 153, 201 and 258 g crude protein (nitrogen x 6.25; CP)/kg dry matter (DM). The rations also contained 16.29, 16.96 and 17.24 mJ metabolizable energy (ME)/kg DM so that the CP:ME values were...
