Residuos de plaguicidas organoclorados en suelos agrícolas.

Abstract: La actividad agricola del estado de Sonora se caracteriza por ser de las mas desarrolladas del pais, es altamente productiva, tecnificada y generadora de divisas. Para mantener las demandas del mercado ha sido necesario implementar cultivos intensivos y el uso indiscriminado de agroquimicos, lo que ha provocado la contaminacion del suelo. Los plaguicidas organoclorados (POC’s) fueron utilizados desde l950 hasta 1991, principalmente en el cultivo de algodon. En paises industrializados fueron prohibidos o restringidos desde 1970 y en Mexico a partir de 1991. Los POC’s representan un riesgo para la salud y el medio ambiente por su toxicidad, bioacumulacion, volatilidad y persistencia; es por ello, que a traves del Convenio de Estocolmo, los paises adheridos estan comprometidos a su reduccion o eliminacion. El objetivo del presente trabajo fue verificar la presencia de los POC’s en suelos de las principales zonas agricolas (ZA) del estado de Sonora. Se extrajeron 17 POC’s por el metodo de dispersion de matriz en fase solida (DMFS) y analisis por cromatografia de gases. Se muestrearon 45 campos donde se recolectaron cinco muestras de suelo (capa superficial y 60 cm de profundidad) y se entrevisto a los encargados para conocer los cultivos historicos y aplicacion de POC’s. El 100% de los entrevistados manifesto haber utilizado POC’s. Los porcentajes de recuperacion fueron del 78 al 116% con CV < 20%. Los residuos de POC’s estuvieron en un rango de no detectados (nd) a 45.75 µg kg-1. En Caborca: 1.22-9.62, Hermosillo: nd-7.49, Magdalena: 0.73-24.40, Ures: nd-18.78 y Guaymas: 1.43-45.75. Los de mayor incidencia fueron: DDE, endosulfan, a-clordano, heptacloro epoxido y endrin. La correlacion positiva entre la materia organica y los POC’s, puede propiciar su acumulacion en los suelos agricolas analizados. Estos resultados indican que las ZA de la entidad estan contaminadas y son un riesgo para la salud y el medio ambiente.

Schuurs–Hoeijmakers Syndrome (PACS1 Neurodevelopmental Disorder): Seven Novel Patients and a Review

Abstract: Schuurs–Hoeijmakers syndrome (SHMS) or PACS1 Neurodevelopmental disorder is a rare disorder characterized by intellectual disability, abnormal craniofacial features and congenital malformations. SHMS is an autosomal dominant hereditary disease caused by pathogenic variants in the PACS1 gene. PACS1 is a trans-Golgi-membrane traffic regulator that directs protein cargo and several viral envelope proteins. It is upregulated during human embryonic brain development and has low expression after birth. So far, only 54 patients with SHMS have been reported. In this work, we report on seven new identified SHMS individuals with the classical c.607C > T: p.Arg206Trp PACS1 pathogenic variant and review clinical and molecular aspects of all the patients reported in the literature, providing a summary of clinical findings grouped as very frequent (≥75% of patients), frequent (50–74%), infrequent (26–49%) and rare (less than ≤25%).

기독교 사역과 Leadership

Abstract: Building Leadership Effectiveness This program encourages leaders to develop practices that transform values into action, vision into realities, obstacles into innovations, and risks into rewards. Participants will be introduced to the five practices of exemplary leadership: modeling the way, inspiring a shared vision, challenging the process, enabling others to act, and encouraging the heart Coaching & Communicating for Performance Coaching & Communicating for Performance is a highly interactive program that will give supervisors and managers the opportunity to build skills that will enable them to share expectations and set objectives for employees, provide constructive feedback, more effectively engage in learning conversations, and coaching opportunities. Skillful Conflict Management for Leaders As a leader, it is important to understand conflict and be effective at conflict management because the way conflict is resolved becomes an integral component of our university’s culture. This series of conflict management sessions help leaders learn and put into practice effective strategies for managing conflict.

Soil and water losses from new citrus orchards growing on sloped soils in the western Mediterranean basin

Abstract: Ten representative research sites were selected in eastern Spain to assess soil erosion rates and processes in new citrus orchards on sloping soils. The experimental plots were located at representatives sites on limestone, in areas with 498 to 715 mm year−1 mean annual rainfall, north-facing slopes, herbicide treated, and new (less than 3 years old) plantations. Ten rainfall simulation experiments (1 h at 55 mm h−1 on 0·25 m2 plots) were carried out at each of the 10 selected study sites to determine the interill soil erosion and runoff rates. The 100 rainfall simulation tests (10 × 10 m) showed that ponding and runoff occurred in all the plots, and quickly: 121 and 195 s, respectively, following rainfall initiation. Runoff discharge was one third of the rainfall, and sediment concentration reached 10·4 g L−1. The soil erosion rates were 2·4 Mg ha−1 h−1 under 5-year return period rainfall thunderstorms. These are among the highest soil erosion rates measured in the western Mediterranean basin, similar to badland, mine spoil and road embankment land surfaces. The positive relationship between runoff discharge and sediment concentration (r2 = 0·83) shows that the sediment availability is very high. Soil erosion rates on new citrus orchards growing on sloped soils are neither tolerable nor sustainable. Copyright © 2009 John Wiley & Sons, Ltd.
