When pumping from a single well in a real (heterogeneous) aquifer, the steady state drawdown at the well is proportional to the pumping rate through a value called the equivalent transmissivity, Tea, which, in short, is the value that best suits Thiem's formula. Equivalent transmissivity is not a local value, but some representative value of a certain area surrounding the well. By means of nume...

A prospective study on children under six months old living in an urban area on the periphery of Rio de Janeiro was carried out to examine the possible effect of diarrhea in differentiating the monthly growth rate in weight and height, according to type of nursing. The results seem to indicate that infants show a delay in growth of weight and height as a result of greater incidence and prevalen...

T HREE ENZYME/COFACTOR complexes form on cell surfaces in tightly regulated reactions during normal blood coagulation in vivo. The enzymes of these complexes, factor VIla, factor IXa, and factor Xa, are ancestrally related serine proteases that are members of the vitamin K-dependent group of clotting factors. Each is generated during blood coagulation by limited proteolysis of a zymogen precurs...

A preliminary qualitative analysis of genetic variability status in Astyanax fasciatus (Cuvier, 1819) from upper Tibagi River headwaters and Vila Velha State Park (VVSP) was carried out by enzymatic digestion (RFLP) of DLoop region from mtDNA. The results showed that Tibagi and VVSP populations were genetically different.

We experimentally study the effects of introducing a forward market and of increasing the number of competitors in a quantity-setting market under strictly convex production costs. Our key interest is to better understand which of these two remedies is more effective at enhancing competition. Allaz and Vila (1993) theorized that forward markets can have a pro-competitive effect under linear pro...
