The atomic diffusion in the FeAl intermetallic compound with B2 ordered structure were studied by the kinetic Monte Carlo method. We use the pair interactions up to second neighbors with periodic boundary conditions to avoid surface effects. Diffusion constants was determined as a function of temperature, covering both ordered and disordered phases. In addition, we calculate the autocorrelation function which shows first, highly correlated jumps of the vacancy in the lattice at low temperatures and second, the atoms that jump to positions of its own sublattice at moderate temperatures.

The aim of this study was to detect antibodies against the virus of Aujeszky’s disease (ADV) in low level management pig farms in Lima, Peru. Blood samples were collected (n=463) from apparently healthy pigs, regardless of sex and mostly between 130 to 150 days old. The animals were from 13 districts of Metropolitan Lima. Neutralizing antibodies against ADV were analysed by the virus neutralization test. All samples resulted negative to antibodies against ADV.

El objetivo del presente estudio fue detectar anticuerpos contra el virus de la enfermedad de Aujeszky (EA) en porcinos de crianzas semi-tecnificadas de Lima metropolitana. Se colectaron 463 muestras de sangre de cerdos sin distinción de sexo y mayormente entre 130 a 150 días de edad, aparentemente normales, en un centro de beneficio de Lima, Perú. Los cerdos procedían de 13 distritos de Lima Metropolitana. Se detectaron anticuerpos neutralizantes contra el virus de la EA mediante la prueba de neutralización viral. Todas las muestras resultaron negativas a anticuerpos contra el virus de la EA.

Se presenta un caso de paciente con dolor abdominal asociado a ictericia y hemorragia digestiva alta (hematoquezia, melena) causado por hemobilia secundaria a ruptura de pseudoaneurisma de una rama de la arteria hepática derecha. El diagnóstico se realizó por medio de endoscopía digestiva alta, realizando arteriografía con embolización selectiva cesando el sangrado.

The aim of this study was to determine antibodies against the bovine viral diarrhea virus (BVDv) in serum samples of adult goats, females and males, of intensive, semi-extensive and transhumant production systems, from 89 farmers of four provinces of the department of Lima: Huaura (n=196), Huaral (n=233), Canta (n=153) and Lima (n=172). The detection of neutralizing antibodies against the BVDv in serum samples (n=754) was done by the viral neutralization test. The results showed that 1.2% (9/754) of the samples had antibodies against the virus. Seroreactive samples were from transhumant goats from the provinces of Canta and Huaura.

El objetivo del presente estudio fue determinar anticuerpos contra el virus de la diarrea viral bovina (VDVB) en muestras de suero de caprinos adultos, hembras y machos, de crianza estabulada, semi-extensiva y trashumante, pertenecientes a 89 criadores de cuatro provincias del departamento de Lima: Huaura (n=196), Huaral (n=233), Canta (n=153) y Lima (n=172). La detección de los anticuerpos neutralizantes contra el VDVB en muestras de suero (n=754) se hizo mediante la prueba de neutralización viral. El 1.2% (9/754) de las muestras presentaron anticuerpos contra el VDVB. Las muestras serorreactoras fueron de cabras de crianza trashumante de las provincias de Canta y Huaura.

The aim of the present study was to detect the RNA of the Bluetongue virus (BTV) in Culicoides insignis and in blood samples of sheep reared under an extensive production system in Pucallpa, Peru. In a first phase, sheep blodd samples (n=46) were obtained from three farms to detect serum antibodies against BTV by agar gel immunodiffusion (AGID) and a competitive ELISA. Results showed that 46.7, 81.3 and 20.0% of sheep had antibodies by IDGA, of which 96% were positive to antibodies against VTV by the ELISA test. In the second phase, 1143 Culicoides spp were captured and 15 sheep blood samples were collected in the seropositive farms. One thousand females of Culicoides insignis were identified. The females were grouped into pools of 100 each (C. insignis = 10 pools and Culicoides spp = 1). For the molecular analysis, the extraction of total RNA was carried out from the ovine blood samples...

CLIMANDES is a pilot twinning project between the National Weather Services of Peru and Switzerland (SENAMHI and MeteoSwiss), developed within the Global Framework for Climate Services of the World Meteorological Organization (WMO). Split in two modules, CLIMANDES aims at improving education in meteorology and climatology in support of the WMO Regional Training Center in Peru, and introducing user-tailored climate services in two pilot regions in the Peruvian Andes. Four areas were prioritized in the first phase of CLIMANDES lasting from 2012 to 2015 to introduce climate services in Peru. A demand study identified the user needs of climate services and showed that climate information must be reliable, of high-quality, and precise. The information should be accessible and timely, understandable and applicable for the users’ specific needs. Second, the quality of climate data was enhance...

The aim of this study was to conduct a haematological evaluation of dogs and cats in Lima, Peru. A total of 460 blood samples (410 dogs and 50 cats) were collected between December 2017 and May 2018. The smears were stained with Wright and the reticulocytes were stained with Brilliant cresyl blue. Descriptive statistics were performed for quantitative variables in the erythroid, myeloid and lymphoid series, as well as the frequency analysis of qualitative variables between species indicator of type of anaemia and leukaemia, ability of medullary regeneration, abnormal morphological changes, out of physiological range and presence of extra and intracellular microorganisms. The most frequent alterations were normochromic normocytic anaemia (23.2% dog, 10% cat), megaloblastic anaemia (5.1% dog), severe hypochromic microcytic anaemia (4% cat), neutrophilic chronic myeloid leukaemia (7.1% dog,...
