The Jorge Basadre Grohmann National University is a public university located in the city of Tacna, Peru. It was founded by Decree Law No. 1894 on August 26, 1971; academic activities started on May 13, 1972. The university is named after Jorge Basadre, a renowned Peruvian historian born in Tacna. Currently, the university is known by the acronym UNJBG and prepares students for 30 careers. Wikipedia.

Under certain conditions of temperature, time and deformation, static recrystallization of austenite in microalloyed steels can be temporarily inhibited by means of the strain-induced precipitation of nanoparticles that cause a pinning effect on austenite grain boundaries in motion. This inhibition can be seen by the formation of a "plateau" in the curves of static recrystallization of austenite obtained from double-deformation tests carried out under isothermal conditions. In this work, several microalloyed steels with different compositions are studied by hot torsion tests in order to characterize the kinetics of recrystallization and its inhibition. The precipitation state in austenite is studied in several samples by means of transmission electron microscopy. The influence of the type of microalloying element (Al, Nb, V) and the mean size of the precipitates on the duration time of the plateau is studied and relationships between these variables can be obtained. Particularly, it is seen that Al-alloyed steels present a much coarser particle size and a considerably shorter plateau compared to Nb and V-microalloyed steels. © (2013) Trans Tech Publications, Switzerland.

Salmonidae were introduced in the Peruvian freshwaters during the first quarter of the 20th century with the Rainbow Trout, Oncorhynchus mykiss (Walbaum, 1792), and later with three more species: Salmo trutta Linnaeus, 1758, Salvelinus namaycush (Walbaum, 1792) and Salvelinus fontinalis (Mitchill, 1814). Only Oncorrynchus mikyss seems to have established itself extensively and successfully, is regularly reported and appears on the taxonomic checklists. This article reports on the presence of Salvelinus fontinalis in the high Andes of southern Peru, an area which is biogeographically associated with the Lake Titicaca Plateau. © 2013 Check List and Authors.

Cysticercosis is a neglected and endemic disease in Peru that commonly affects the central nervous system (CNS), causing neurocysticercosis (NCC). However, only a few reports of disseminated cysticercosis (DCC) exist in the world. In this article we present a case report of a male, 82 year old patient from the department of Junin (Peru). He presented a sudden loss of consciousness associated with generalized tonic-clonic seizures. CT scan and brain MRI showed multiple cystic lesions with scolex presence inside and compatible with massive NCC. Thoracic, abdominal and pelvic MRI showed multi-organ dissemination of cysticerci. Although there is little therapeutic experience in cases of DCC, the patient received deworming treatment with albendazole and corticoids, in this way a favorable clinical outcome was achieved without complications during hospitalization.

The kinetics of static recrystallization of austenite and its transitory inhibition by straininduced precipitates have been characterized in several microalloyed steels with different compositions. This inhibition can be seen by the formation of "plateaus" in the curves of static recrystallization obtained from isothermal double-deformation tests. The influence of the type of microalloying element (Nb, V, Al) and the mean size of the precipitates on the duration time of the plateau of recrystallization inhibition has been studied and empirical relationships between these variables have been obtained. Al-steels present a much coarser particle size and a considerably shorter plateau compared to Nb and V-microalloyed steels. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. Source

INTRODUCTION: The mortality perinatal is a risks indicator deadly related to the reproduction and it shows the prenatal attention, during the childbirth and post childbirth. OBJECTIVE: Identifying risk factors associated to mortality perinatal in hospitals of the Health Ministry of the Peru and determining his capability predictive. METHODS: I study prospective, analytical, of cases and controls, in 23 hospitals of Health Ministry; of 48 422 births attended January to June 2008, cases were 951 deaths perinatales (fetal death overdue and 1000 g precocious neobirth to more) and the controls 951 born living persons, selected candidates at random. Mortality rate for thousand births, Odds Ratio with his trustworthy interval was utilized to the 95%. SPSS Utilized statistical parcel himself. RESULTS: The death rate perinatal was 19.64 for thousand births, the fetal overdue 10.74 and precocious neobirth 9.03. The risk factors went: maternal age 35 years to more (OR=2,07), educational level illiterate or primary (OR=1.97), great multiparity (OR=2.07), deadly antecedent fetal (OR=3.17), birth in saw or jungle (OR=1.47), maternal pathology (OR=2.53), prenatal control missing or inadequate (OR=2.26), anomalous presentation (OR=2.61), I start of childbirth once was induced or elective cesarean operation (OR=2.28), I work of childbirth once was precipitated or once was extended (OR=4.70), liquid amniotic green (OR=3.99), Cesarean operation (OR=1.60), depression right away (OR=43.75) and five minutes (OR=106.28), prematurity (OR=22.89), under weight (18.02), fetal malnutrition (OR=6.97) and pathology newborn (OR=21.9). The pathology newborn, depression to the being born, under weight and prematurity, they had high value predictive (91%). Conclusion, the risk factors of the newborn have principal association and high value predictive in order to the mortality perinatal in hospitals of Health Ministry of the Peru. Source
