The objective of the study was to determine the prevalence of Trypanosoma sp. in healthy cattle that are reared in four districts (Callería, Campo Verde, Masisea and Yarina) of the Coronel Portillo Province, Ucayali, using the Woo and the buffy coat stained with Giemsa techniques. The latter was also used to determine the species of trypanosome involved. A total of 289 blood samples were collected in May-July, 2000 from crossbred Zebu cattle. Animals were 8 months till 16 years of age, and managed under an extensive rearing system. The morphometric identification showed that the prevalent species was Trypanosoma vivax. The prevalence of T. vivax was 22.2 ± 4.8% when the Woo technique was used and 5.9 ± 2.7 when the stained smear was used. The Campo Verde district had the higher frequency of positive animals (97%, 62/64). None of the animals showed clinical signs of the disease and onl...

The current approach of quality within organizations has changed from the securing level to the continuous improvement level. The NTP-ISO 9000:2001 Series of Norms can confirm this and show how, unlike its previous version, it emphasizes on a continuous improvement in process quality.

This article describes the quality costs as the quality has evolved, and then analyzes the cost approach and the quality of the new approach that distinguishes the quality and cost of poor quality, shows the most common prevention costs quality, quality assessment and internal and external costs of poor quality. And take into consideration the importance of a partnership between the state and to form a National Entrepreneurship Network Quality, to support the importance of this network I take as an example a study in the State of Israel.

The demand for emerging technology in making executive decisions , allows to have information systems that support this task from large volumes of information from management systems and integrated modern computer platform . The following article helps planning management information systems facilitating needed to reach such a global model integration and organization for overall management overview . The total management involves an integrated manner with control indicators since the birth of the business idea to the economic boom and the high altitude flight of profitability or industry manned by their managers and owners trying to keep the latter activity possible longer periods even if it has complied with the period of return on investment.

The difference between the number of ISO 9000:1994 Standards NTP and NTP ISO 9000:2001 is the first priority assurance, and the second improvement. in this article is intended to illustrate the major changes and benefits that come with the new version of the series ISO 9000:2001 Standards NTP

Abdominal obesity represents an accurate predictor of overall morbidity and mortality, which is worrisome because it is also continuously increasing across Andean countries. However, its relationship with altitude remains unclear. The objective of this study was to assess the association between altitude and abdominal obesity in Peru, and how sociodemographic variables impact this association. Methods: We estimated the prevalence of abdominal obesity in Peru and analyzed its association with altitude using the data from the 2012-2013 National Household Survey (ENAHO). During this survey, a representative sample of Peruvians was screened for abdominal obesity, using waist circumference as a proxy, and the Adult Treatment Panel III guidelines cutoffs.

Background Detection of anti-SARS-CoV-2 antibodies among people at risk of infection is crucial for understanding both the past transmission of COVID-19 and vulnerability of the population to continuing transmission and, when done serially, the intensity of ongoing transmission over an interval in a community. We aimed to estimate the seroprevalence of COVID-19 in a representative population-based cohort in Iquitos, one of the regions with the highest mortality rates from COVID-19 in Peru, where a devastating number of cases occurred in March, 2020. Methods We did a population-based study of SARS-CoV-2 transmission in Iquitos at two timepoints: July 13–18, 2020 (baseline), and Aug 13–18, 2020 (1-month follow-up). We obtained a geographically stratified representative sample of the city population using the 2017 census data, which was updated on Jan 20, 2020. We included people who we...
