This article discusses several key concepts for human resources policy in health in the context of Latin America's regional integration efforts. The article focuses on different concepts of integration to emphasize the analytical distinction between regional and conceptual integration. It also presents labor and human resources concepts before discussing, in the final analysis, the challenges t...
BACKGROUND Chronic low back pain is considered as a high-impact condition that affects the working population of Latin America, with long reaching social and economic repercussions. Its true frequency is unknown due to the absence of well-designed clinical trials that use standardized definitions and criteria. OBJECTIVES To evaluate the prevalence of chronic non-specific low back pain among t...
abstract ion selective electrodes (ises) are electrochemical sensors that respond selectivity to the activity of ionic species. an ion-selective electrode is an electrochemical device that uses a thin selective membrane or film as the recognition element, and is an electrochemical half-cell equivalent to other half-cells of the zeroth (inert metal in a redox electrolyte). in common methods o...
Latin America and the Caribbean have not yet developed strong clinical cancer research programmes. In order to improve this situation two international cancer organisations, the Latin American Society of Clinical Oncology (SLACOM) and the European Society of Medical Oncology (ESMO) worked closely with the Peruvian Cooperative Oncology Group (GECOPERU) and organised a clinical cancer research wo...
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
abstract in aggregate, active forms of reactive silica with mineral names are sometimes associated with sand and gravel in concrete mixture. alkali hydroxides originated from alkalis in the cement or other resources form an alkaline silica gel with this reactive silica which becomes swallowed and expanded during time causing damage to concrete. there have been growing researches on alkaline r...
Compressive sensing (sparse recovery) is a new area in mathematical image and signal processing that predicts that sparse signals can be recovered from what was previously believed to be highly incomplete measurement [3, 5, 7, 12]. Recently, the ideas of this field have been extended to the recovery of low rank matrices from undersampled information [6, 8]; most notably to the matrix completion...
