The present study aimed to describe and analyse the results of bacterial isolates and their antibiograms in canine patients with a diagnosis of urinary tract infection, which were treated at the Small Animal Clinic of the Faculty of Veterinary Medicine of Universidad de San Marcos between 2012 and 2017. In total, 97 medical records of patients who had urine cultures and antibiograms exams were identified. The bacterial agents isolated were Escherichia coli (36.9%), Staphylococcus sp (28.7%), Proteus sp (27.9%), Pseudomonas sp (3.3%), Klebsiella sp (1.6%), Streptococcus sp (0.8%) and Citrobacter sp (0.8%) These evidenced a high antibiotic resistance due possibly to the inappropriate use of antibiotics in the country, so it is not possible to recommend a safe initial treatment in canine patients with presumptive diagnosis of this disease.

Potential risks associated with the cuttings re-injection process as an alternative method for drilling wastes disposal were identi- fied and assessed in two offshore platforms located at the southwest of the Campeche Sonda in Mexico. Risks were evaluated using the HAZOP methodology, to identifying hazards in 11 nodes. In addition, deviations in the process were analyzed, and each risk analyzed was categorized as tolerable or non-tolerable and providing some recommendations. Consequences derived from accidental spills of slurry and/or cuttings were analyzed using the mathematical model YAXUM 3D to simulate the pollu- tants dispersion in seawater in three different climatic periods. The results of the consequences analysis shows that even the concentrations in the discharge point exceeded the recommended criteria for protection of the marine life and seawater quality, the spill is rapidly...

In this work the anthelmintic potential of the aqueous and hydroalcoholic extracts of two plants used in traditional medicine as antiparasitic, Carica papaya and Plantago major, commonly known as papaya and plantain, respectively, was evaluated. The results obtained showed that the extracts of both plants possess anthelmintic activity causing mortality of C. elegans, in different concentrations. Based on the determination of LC50, the hydroalcoholic extract of P. major leaves (2,663 mg / ml) induced a mortality 40.5% higher than that of the aqueous extract (4,420 mg / ml); whereas in C. papaya the aqueous extract (2,012 mg / ml) caused a mortality 40% higher than the hydroalcoholic extract (3,350 mg / ml). The results are discussed based on the anthelmintic potential of each extract.

The chlorophyll a is an indicator of the plankton biomass for track flows, jets and oceanographic feathers and is used as an entry for primary production models. The chlorophyll a in the Peruvian sea surface can be measured by means of satellite remote sensing in the visible spectral range from 0.4 to 0.7 μm. This work aims to develop a physical model for the estimation of chlorophyll a concentration from the MODIS images in the Peruvian sea.

The chlorophill a in the Peruvian sea must be measured by means of remote sensing in the visible range. The objective of the present work is to determine the chlorophill a concentration using MODIS images from the Peruvian sea. The mean monthly concentration maps of chlorophill a of January, February, March and April of 2006 year has been obtained from the MODIS-AQUA images. In each monthly image the chlrophill a concentration is greater near to coastline and decrese gradually far from the coast. In the Northern coast (0-5°S), the chlorophill a vary between 0.05 to 0.5 g/cm3 and it disperse far from the coast. In the Central coast (5°-15°S) the chlorophill a vary between 10 to 30 g/cm3, it’s more dense in the coastline and diminished conform the distance from the coast is increased. In the Southern coast (15°-20°S) the chlorophill a vary between 3 to 5 g/cm3 very near to the coast...

La investigación se realizó en la Estación Experimental Agraria - INIA: "El Porvenir", ubicada a 13.2 km de la ciudad de Tarapoto, Región San Martín. Se realizaron evaluaciones con 18 vacas F1 (Gyr x Holstein), desde 2004 hasta 2010. Recolectándose la información de cuatro lactancias a fin de determinar las curvas de lactancia con el modelo Matemático Gamma Incompleto fueron obtenidas utilizando el procedimiento NLIN del programa estadístico Statistical Analysis System. El manejo se realizó en un sistema semiextensivo, cuidado en pastos Brachiaria brizantha, Pasto de corte Penissetum purpureum y plantas de maíz, y suplementado con concentrado con 14% de proteína al momento del ordeño, dos veces al día. Los promedios de producción total para la primera a la cuarta lactación fueron 4338, 4370, 4939 y 4785 kg de leche, con un promedio de días de lactación de 407, 347, 384 ...

Objective: Describe the association between asthma control and adherence to treatment in patients of the Hospital Nacional Dos de Mayo 2019-2020. Materials and methods: A quantitative, descriptive and retrospective clinical study was carried out during the 2019-2020 period in asthmatic patients from the Hospital Nacional Dos de Mayo (HNDM). The relationship between control and adherence to treatment in patients seen in the Asthma office of the Pneumology Service was evaluated by collecting data: Inhaler adherence test (TAI), Asthma control test (ACT) age, sex, treatment established, time of illness and nutritional assessment, through the review of medical records. Statistical analysis was performed with IBM SPSS Statistics version 22 software and the chi-square statistical test was performed to determine the association. Results: 187 patients were evaluated through medical records, 84 me...

This scientific article evaluates the prediction of hydrometeorological variables, which refer to temperature, precipitation, and flow. The applied methodology is long-term bidirectional recurrent neural networks (BRNN) in a series of 40 years of study for a better perspective on the climatological conditions in Metropolitan Lima until the year 2050. The BRNN model is formed by a single series of past observations, which means that the model analyzes one variable simultaneously to project the next value in the sequence, and unlike other LSTM models, the bidirectional model can model complex and long-time series of sequences efficiently. The purpose of the model is to divide the neurons of a regular RNN into 2 directions, one of them is for the positive time direction (forward states), and one is for the negative time direction (reverse states). In addition, mean square error (MSE), root ...

Objective: Validation of a survey for making an indirect diagnosis of abuse/dependence of alcohol survey in the Peruvian Andes. Material and method: We used the database of The Mental Health Epidemiological Study conducted in the Peruvian Andes in 2003, which includes surveys assessing mental health. We used the direct diagnosis of alcohol abuse/dependence module in adult males, and indirect diagnosis of alcohol abuse/dependence survey in their spouses. The sample size was 1,302 adult couples. Cronbach’s Alpha coefficient was used in order to verify reliability of the tests. Validity of criteria was obtained by comparing them with the direct questionnaire and the validity of the construct was determined by using a factorial analysis. Results: The internal consistency of the questionnaire was 93.1%. The estimated probability of matching between the indirect survey and the ...

Se presentan los principales resultados de un proyecto de investigación en el que se realizaron ensayos de simulación sísmica en construcciones de adobe a escala natural. Los especímenes fueron representativos de viviendas rurales de un piso. Las señales de excitación dinámica, derivadas de un registro obtenido durante un terremoto en el Perú, simularon movimientos sísmicos de intensidad creciente. El principal objetivo de la investigación fue evaluar la influencia de mejoras en las técnicas constructivas y del empleo de sistemas de refuerzo en el comportamiento sísmico de las edificaciones de adobe. Se comprobó que, aunque es recomendable mejorar la calidad de los materiales y las técnicas de construcción, es indispensable incluir sistemas de refuerzo adecuados para garantizar la seguridad de las viviendas de adobe en zonas de alta sismicidad.
