espanolLa investigacion se realizo en Celendin - Cajamarca, a 2893 msnm, con el objetivo de determinar el efecto del pastoreo de vacas lecheras a estaca sobre el consumo (Kg MS) y condicion de la pastura raigras-trebol blanco, durante la epoca de lluvia. La muestra poblacional para determinar el consumo estuvo conformada por 117 vacas de raza Holstein, Brown swiss y Holstein x Brown swiss; y para condicion de la pastura, por 120 hectareas. El consumo se determino midiendo el area de pasto asignado diariamente a los animales y 2cortando la pastura a ras del suelo, un minimo de tres muestras, utilizando cuadrantes de 1 m; las muestras fueron transportadas al Laboratorio de la Universidad Nacional de Cajamarca y colocadas en estufa a 105°C durante 24 horas. La condicion de la pastura se baso en plantas forrajeras deseadas, suelo desnudo, especies no deseadas, aporte de leguminosas, vigor, uniformidad de uso, evidencias de sobrepastoreo y de compactacion extrema del suelo. Se uso la estadistica descriptiva con sus respectivos promedios, desviacion estandar y coeficiente de variabilidad. Los animales consumieron en promedio 10.9 kg MS (2.6% de su peso vivo).

EnglishThe research was carried out in Celendin, Cajamarca, at 2893 m.a.s.l., in order to determine the effect of grazing dairy cows on consumption (Kg MS) and the condition of the raigras-white clover pasture during the rainy season. The population sample to determine consumption was made up of 117 Holstein, Brown Swiss and Holstein x Brown Swiss cows; and for pasture condition by 120 hectares. Consumption was determined by measuring the pasture area assigned to the animals daily and by mowing the pasture at ground level, a minimum of three samples, using 1 m2 quadrants; the samples were transported to the Laboratory of the National University of Cajamarca and placed in an oven at 105°C for 24 hours. The condition of the pasture was based on desired fodder plants, bare soil, unwanted species, legume input, vigor, uniformity of use, evidence of overgrazing and extreme soil compaction. Descriptive statistics were used with their respective averages, standard deviation and coefficient of variability. The animals consumed an average of 10.9 kg MS (2.6% of their live weight).

The present research work is of simple descriptive non-experimental design and was carried out with the purpose of determining the proximal analysis of proteins, iron and calcium in dry samples of Nostoc sphaericum “cushuro” from the Laguna de Conococha, District of Catac, Province of Huaraz, Department of Ancash. The analysis of results was performed in the Excel 2016 program, through descriptive statistical parameters as average and standard deviation. For the determination of proximal analysis in 100g of pulverized Nostoc sphaericum “cushuro”, the Kjeldahl method was used, finding 26.68 ± 0.01% protein, 0.21 ± 0.03% fat, 5.77 ± 0.11% crude fiber, 11.23 ± 0.42% moisture, 7.77 ± 0.01% ash. For the determination of iron, the colorimetric method based on reactions with orthoferantothroline was used, finding 15.72 ± 2.07 mg/100g of dry sample, and for calcium the complexometric method was applied by titration with ethylenediamine tetraacetic acid (EDTA), obtaining 1224.4 mg of Ca/100g of dehydrated “cushuro” as a result. It is concluded that dehydrated Nostoc sphaericum “cushuro” is important in the diet because of its high protein, iron and calcium content and indispensable for its use in the treatment of anemia, malnutrition and osteoporosis.

The objective was to isolate bioflocculant-producing lactic acid bacteria (LAB) from residual sugarcane juice. For this reason, sugarcane juice samples were obtained from 15 randomly sampled residual sugarcane stalk samples. The isolation of LAB was then carried out by means of conventional microbiology techniques, using Agar Mayeux, Sandine and Elliker (MSE) culture medium at pH 7.2 and an incubation time of 30°C for 48 hours. Subsequently, pure cultures were made from the characteristic colonies of Leuconostoc mesenteroides (rubbery, viscous, translucent and creamy colonies) for their biochemical identification according to Bergey’s Manual of Bacteriological Determination. The identification and selection of L. mesenteroides subsp. mesenteroides was carried out according to the Kappa coefficient statistical method, with the purpose of using it in the production of dextran (bioflocculant) in an aerated-agitated bioreactor (Aplikon brand). The purity of the dextran was determined using the FT-IR technique, which was compared with the spectrum of pure dextran produced by the strain NRRL P-640. Four strains of Leuconostoc mesenteroides, LM (01-04) were isolated, of which the strain LM03 was identified as L. meenteroides subsp. mesenteroides. The dextran values produced by LM03 were 26.87 g/L at 80 hours (maximum concentration) and 2.61 g/L at 4 hours (minimum concentration). The dextran produced by LM03 is pure according to FT-IR analysis. In conclusion, it was possible to isolate BAL L. mesenteroides subsp. mesenteroides (strain LM03), which had the capacity to produce dextran, which can be used as a bioflocculant with different biotechnological and industrial uses.

This research focuses its attention on higher education employability observatories, which are understood as platforms that contribute to the employment of their graduates, presenting the results of the activities carried out by the so-called Work Package 4 within the framework of the ERASMUS+ EMPLE-AP project. Since the main objective of the study was to define the scope of a regional labor observatory in the countries of the Pacific Alliance, as well as to determine the articulation of its capacities in relation to the demands of its stakeholders, a qualitative approach of an emergent nature was used, with interviews and focus groups as data collection instruments. As far as the population and sample were concerned, the aforementioned instruments were applied, through the project partners, to professionals and users of labor observatories in Italy, Portugal, Mexico, Colombia, Peru and Chile. Later on, using the content analysis technique, the products, functions, structures and competencies required by the operation of a labor observatory were defined according to the requirements of the project.

The aim was to evaluate lichen as an indicator of air pollution caused by vehicles in three areas of the district of Cajamarca: Av. El Maestro, Plazuela Miguel Grau and the park of Urbanizacion Cajamarca, during the period April - August 2017. The area occupied by each lichen species was processed using Adobe Photoshop CS6 Extended - Version 13.0 64 bits, and it was processed in cm2. The traffic flow, as well as the abundance and richness of the lichen species, was determined for each of the three zones using a 0.50 m x 0.10 m grid (divided into grids of 20 cm2). These last two indicators were used to determine the Atmospheric Purity Index (API). The vehicle count was done per minute, in 5-minute intervals, for one hour. The analysis determined significant differences in the indicators between the areas (p<0.0001). It was determined that the zone with the highest vehicle flow (Jr. Amalia Puga, 36 veh/min) also presented lower abundance (34.8 cm2) and richness of lichens (1.8 sp) and therefore, a lower API (13.8), unlike the zone that presented lower vehicle flow (Parque Urbanizacion Cajamarca, 0 veh/min), with higher abundance (192.7 cm2) and richness of species, and consequently a higher API (64.1).
在2017年4月至8月期间，目的是评估地衣作为卡哈马卡地区三个地区(Av. El Maestro, Plazuela Miguel Grau和Urbanizacion Cajamarca公园)车辆造成的空气污染指标。采用Adobe Photoshop CS6 Extended - Version 13.0 64位处理，以cm2为单位进行处理。交通流量以及地衣物种的丰度和丰富度，使用0.50 m x 0.10 m的网格(划分为20 cm2的网格)来确定三个区域中的每个区域。最后两个指标用于确定大气纯度指数(API)。车辆计数每分钟进行一次，间隔5分钟，持续1小时。分析确定了地区间指标的显著差异(p<0.0001)。结果表明，交通流量最大的区域(Jr. Amalia Puga, 36 veh/min)地衣的丰度和丰富度也较低(34.8 cm2)，因此地衣的API较低(13.8 sp)，而交通流量较小的区域(Parque Urbanizacion Cajamarca, 0 veh/min)地衣的丰度和丰富度较高(192.7 cm2)，因此地衣的API较高(64.1)。

The present work was carried out with the purpose of evaluating the effect of the nutritional program on body composition in patients with metabolic syndrome. The design was pre-experimental in a sample of 22 selected workers out of 60 identified with metabolic syndrome, belonging to the Citizen Security Management of the Municipality of Victor Larco of the city of Trujillo, to whom a nutritional program was applied with follow-up of a individualized diet plan between 2000 and 2200 calories for 8 months. The presence of metabolic syndrome was identified using the criteria of the Latin American Diabetes Association (ALAD) 2018. Glycemia and lipid profile were determined with the use of the Accu Chek® Performa Nano glucometer and Mission Cholesterometer respectively, and body composition through bioimpedance with the Maltron 920-II equipment. 61.86% of the workers presented metabolic syndrome and 72.16% had an atherogenic risk. After the application of the nutritional program, the% fat is reduced from 33.52 ± 6.41% to 31.56 ± 7.02% (p <0.05), an increase in the fat-free mass from 66.48 ± 6.41 to 68.44 ± 7.02% (p <0.05 ), a non-significant increase in muscle mass 28.68 ± 4.44 to 29.73 ± 4.75 kg and similarly with body protein from 12.58 ± 1.88 kg to 13.02 ± 2.05 (p = 0.223). It is concluded that the nutritional program improved the body composition in the% fat and fat-free mass, but not in the BMI, requiring more emphasis on physical activity.
