Growing conditions affect the phytochemical composition of edible wall rocket (Diplotaxis erucoides)

[EN] Wall rocket (Diplotaxis erucoides) is a wild vegetable with the potential to become a crop of high antioxidant quality. The main bioactive compounds include ascorbic acid (AA), sinigrin, and a high content of total phenolic compounds (TP). It also accumulates nitrates. Since these compounds are affected by environmental conditions, adequate crop management may enhance its quality. Eleven accessions of wall rocket were evaluated under field and greenhouse conditions during two cycles (winter and spring) and compared to Eruca sativa and Diplotaxis tenuifolia crops. The three species did not differ greatly. As an exception, sinigrin was only identified in wall rocket. For the within-species analysis, the results revealed a high effect of the growing system, but this was low among accessions. The highest contents of AA and TP were obtained under field conditions. In addition, the levels of nitrates were lower in this system. A negative correlation between nitrates and antioxidants was determined. As a counterpart, cultivation in the field¿winter environment significantly decreased the percentage of humidity (87%). These results are of relevance for the adaptation of wall rocket to different growing conditions and suggest that the field system enhances its quality. The low genotypic differences suggest that intra-species selections in breeding programs may consider other aspects with greater variation.C.G. is grateful to the Ministerio de Educacion, Cultura y Deporte of Spain (MECD) for the financial support by means of a predoctoral FPU grant (FPU14-06798).

Seroprevalence of Porcine torovirus (PToV) in Spanish farms

Background: Torovirus infections have been associated with gastroenteritis and diarrhea in horses, cows, pigs and humans, especially in young animals and in children. Although asymptomatic in a large percentage of cases, however toroviruses may pose a potential threat to worsen disease outcome in concurrent infections with other enteric pathogens. Previous studies based on the analysis of limited numbers of samples indicated high seroprevalences against porcine torovirus (PToV) in various European countries. The aim of this work was to perform a seroepidemiological survey of PToV in Spanish farms in order to define the seroprevalence against this virus. Results: Serum samples (n = 2664) from pigs of different ages were collected from 100 Spanish farms coming from 10 regions that concentrate 96.1% of the 3392 farms with 80 or more sows censused in Spain. Samples were screened by means of an indirect enzyme-linked immune-sorbent assay (ELISA) based on a recombinant PToV nucleocapsid protein as antigen. The analysis of the whole serum collection yielded a total of 95.7% (2550/2664) seropositive samples. The highest prevalence (99.6%, 1382/1388) and ELISA values (average O.D. ± standard deviation) were observed in the sows (1.03±0.36) and the lowest prevalence (59.4%, 98/165) and anti-PToV IgG levels (0.45±0.16) were found amongst 3-week-old piglets. Both ELISA reactivity values and seroprevalence percentages rose quickly with piglet's age from 3 to 11 weeks of age; the seroprevalence was 99.3% (2254/2270) when only the samples from sows and pigs over 11-weeks of age were considered. Antibodies against PToV were detected in all analyzed farms. Conclusions: This report describes the results of the largest torovirus seroepidemiological survey in farmed swine performed so far. Overall, the seroprevalence against PToV in animals older than 11 weeks of age was >99%, indicating that this virus is endemic in pig herds from Spain

Approach to the determination of the impact of the wastewater unloads of the municipality of Ayapel, on the wetland waterquality

RESUMEN: En el municipio de Ayapel, departamento de Córdoba, se realizaron cuatro muestreos de campo con el fin de obtener información representativa de las variaciones horarias del agua residual del municipio como también de la calidad del agua en la zona de influencia de éstas en la ciénaga de Ayapel. En el sector donde se presentan las principales descargas del alcantarillado se determinaron las variables fisicoquímicas y microbiológicas del agua residual doméstica y de la ciénaga. Ello con el fin de determinar el posible impacto de las aguas residuales domésticas sobre la calidad del agua de un sector de la ciénaga de Ayapel. Los resultados del estudio permiten afirmar que existe un impacto de las aguas residuales sobre el complejo cenagoso, sin embargo estas descargas afectan principalmente la calidad ambiental de los sitios aledaños al casco urbano del municipio de Ayapel, principalmente en las épocas de aguas bajas incluyendo la zona pelágica del sector E0.ABSTARCT: In the municipality of Ayapel, department of Cordoba, four field samplings were carried out in order to obtain representative information hour variations of the municipality wastewaters, as also of the water quality in the zone of influence of these waters in the wetland Ciénaga de Ayapel. In the sector where almost all sewage waters are spilled the main physical, chemical and microbiological variables of the domestic wastewater and of the wetland Ciénaga de Ayapel were determined. This was carried out in order to determine the possible impact of domestic wastewaters on the water quality of a sector of the wetland Ciénaga de Ayapel. Results of the study allow to affirm that an impact of wastewaters on the wetland complex exists, nevertheless these waters affect mainly the environmental quality of the sites located near the municipality of Ayapel urban zone, mainly at the low-water level seasons including the limnetic zone of the E0 sector

Importancia de las redes sociales en el reclutamiento de personal en la industria maquiladora en la ciudad de Chihuahua

Prevalence and characteristics of methicillin-resistant staphylococci in goats on the island of Tenerife, Spain

The aim of this study was to determine the prevalence of methicillin-resistant Staphylococcus (MRS) in healthy goats on the Island of Tenerife, Spain, as well as to identify the phenotypic and genotypic characteristics of the strains found. A cross-sectional prevalence study was conducted. A total of 158 goats from 15 different farms were sampled between September 2017 and January 2018. The percentage of positive samples of methicillin-resistant Staphylococcus aureus (MRSA) was 15.8% (25/158) and that of methicillin-resistant coagulase-negative staphylococci (MRCoNS) was 6.9% (11/158). All MRSA isolates from goats belonged to one clonal group showing Multi-Locus Sequence type 398. All strains studied (n = 36) were resistant to non-carbapenem beta-lactam antibiotics and susceptible to teicoplanin, linezolid, vancomycin, rifampicin, quinupristin-dalfospristin and mupirocine. In MRSA isolates, the highest percentage of resistance obtained, besides beta-lactam non-carbapenem antibiotics, was to trimethoprim-sulphamethoxazole and, in the case of MRCoNS isolates, to phosphomycin and erythromycin. A total of 12 resistance patterns were obtained, presenting differences between patterns obtained for MRSA and MRCoNS, with 7 different patterns for MRSA and 5 for MRCoNS. We therefore consider it essential to expand the epidemiological study of these strains of animal origin, as well as to increase surveillance and control measures at all stages of the food chain

Figura 1 Pregunta No. 1,Figura 2 Pregunta No. 2 Fuente: Figura 3 Pregunta No. 3 ,Figura 4 Pregunta No. 4,Figura 5 Pregunta No. 5,Figura 6 Pregunta No. 6,Figura 7 Pregunta No. 7,Figura 8 Pregunta No. 8, Anexo encuesta aplicadaHoy en día la selección del talento humano en una corporación y/o compañía es una de las consecuciones más importantes del día a día; es por eso que este trabajo pretende analizar el proceso de selección del personal de la empresa INTELCIA, con el fin de identificar sus falencias y proponer unas mejoras al mismo. Chiavenato, I. (2009) plantea que la selección busca entre diversos candidatos, a quienes sean más adecuados para los puestos que existen en la organización o para las competencias que necesita; y el proceso de selección, por lo tanto, pretende mantener o aumentar la eficiencia o el desempeño humano, así como la eficacia de la organización. Partiendo de lo anterior se seleccionó una muestra del personal que compone la organización con el fin de identificar sus conocimientos frente al proceso de selección y como este afecta de forma directa e indirecta todos sus componentes. Según los resultados obtenidos en el proceso de selección se logró evidenciar la falta de conocimiento que tiene los empleados sobre mencionado proceso y así mismo las falencias que comete la organización en cuanto a temas de estructuración, socialización y toma de decisiones. Por último, se propone mejora en el proceso de selección del talento humano, de tal manera que se puedan seleccionar los mejores talentos humanos, como al igual que estos conozcan los procesos internos de la compañía en cuanto a temas de vacantes y ascensos.Today the selection of human talent in a corporation and/or company is one of the most important achievements of the day to day; That is why this work aims to analyze the selection process of the personnel of the company INTELCIA, in order to identify its shortcomings and propose improvements to it. Chiavenato, I. (2009) states that the selection seeks among various candidates, those who are most suitable for the positions that exist in the organization or for the skills it needs; and the selection process, therefore, aims to maintain or increase the efficiency or human performance, as well as the effectiveness of the organization. Based on the above, a sample of the personnel that makes up the organization was selected in order to identify their knowledge regarding the selection process and how it directly and indirectly affects all its components. According to the results obtained in the selection process, it was possible to demonstrate the lack of knowledge that employees have about said process and also the shortcomings that the organization commits in terms of structuring, socialization and decision-making issues. Finally, improvement is proposed in the selection process of human talent, in such a way that the best human talents can be selected, as well as that they know the internal processes of the company in terms of vacancies and promotions
