Colombia’s literature is one of its most revered national treasures, yet, paradoxically, it is generally less known outside of its national boundaries than are its internationally recognized visual artists, performance artists, soccer players, and even drug traffickers. Since the 1970s, this international ignorance with respect to Colombian literature has gradually changed, primarily because of...

In the nearly 50 years since the description of Williams syndrome by [Williams et al. (1961); Circulation 24:1311-1318], the focus of scientific inquiry has shifted from identification, definition, and description of the syndrome in small series to genotype-phenotype correlation, pathophysiologic investigation in both humans and in animal models, and therapeutic outcomes in large cohorts. Study...

Since cryptosystem based on the problem of factoring the composite number N can be attacked with P − 1 and P +1 methods, it is required that P −1 and P +1 should be difficult to be factored into many small primes, where we assume that the P is a factor of N . In this paper, first, we consider the distribution of secure primes against both P −1 and P +1 methods. Second, we propose two efficient ...

was also made for n-propyl isocyanide, which was suspected, because of its color, to be contaminated with a small amount of n-propyl iodide. The values of the equilibrium constants were averaged, with the concentration of free isocyanide as a weight factor. The equilibrium constants obtained in this way are 2.0 X 105 for ethyl isocyanide, 1.1 X 105 for n-propyl isocyanide, 1.4 X 104 for isoprop...
