White lupin (Lupinus albus L.), the neglected multipurpose crop: Its production and utilization in the mixed crop-livestock farming system of Ethiopia

A survey was conducted to generate holistic information on the production and utilization of local white lupin in two lupin growing districts, namely, Mecha and Sekela, representing mid and high altitude areas, respectively in North-western Ethiopia. During the survey, two types of participatory rural appraisal (PRA) techniques, namely, individual farmer interview (61 farmers from Mecha and 51 from Sekela) and group discussion (with 20 farmers from each district) were employed. There are significant differences (P<0.05) between the two study districts for the variables like total land holding, frequency of ploughing during lupin planting, days to maturity, lupin productivity, and number of days of soaking lupin in running water. However, there are no significant differences (P>0.05) between the two study districts for the variables like land allocated for lupin cultivation, lupin seed rate, lupin soaking at home, lupin consumption per family per week and proportion of lupin used for household consumption. The use of the crop as livestock feed is negligible due to its high alkaloid content. It is concluded that the local white lupin in Ethiopia is a valuable multipurpose crop which is being cultivated in the midst of very serious shortage of cropland. Its ability to maintain soil fertility and serve as a source of food in seasons of food scarcity makes it an important crop. However, its bitter taste due to its high alkaloid content remains to be a big challenge and any lupin improvement strategy has to focus on minimizing the alkaloid content of the crop.

Minimally invasive approach to lumbosacral decompression in a cadaveric canine model

AIMS To determine efficacy of a minimally invasive (MI) surgical approach using a human MI lumbar retractor for canine lumbosacral dorsal laminectomy and partial discectomy and to compare this technique to the standard open surgical (OS) approach. METHODS Lumbosacral dorsal laminectomy and partial discectomy was performed on 16 large-breed canine cadavers using either a standard OS (n=8) or MI (n=8) approach. Skin and fascial incision length, procedure time, and intraoperative complications were recorded. Postoperatively specimens were evaluated for laminectomy and discectomy dimensions, and visible damage to the cauda equina and exiting nerve roots. RESULTS Median length of skin and fascial incisions in the OS group were longer than in the MI group (p<0.001). Median laminectomy length was similar between both approaches (p=0.234) but width was greater for the MI than OS approach (p=0.002). Both approaches achieved similar partial discectomy width (p=0.279). Overall surgical time was longer for MI approaches compared to OS, with a median of 18.5 (min 15.5, max 21.8) minutes for MI compared to 14.6 (min 13.1, max 16.9) minutes for OS (p=0.001). CONCLUSIONS The MI approach reduced incision lengths while retaining comparable laminectomy and discectomy dimensions. For this in vitro model the MI approach required more time to complete, but this difference may not be relevant in clinical cases. CLINICAL RELEVANCE Dogs undergoing lumbosacral dorsal laminectomy are commonly large-breed dogs. The traditional open approach requires a large skin incision and soft tissue dissection, especially in overweight animals. A MI approach accomplishing the same surgical result while minimising soft tissue trauma could reduce post-operative pain and recovery time, and may lower wound-related complications. Clinical studies are needed to confirm postoperative benefit and assess operating times in vivo.

Water temperature measured in Independence Bay, Pisco, Peru

Independencia Bay can be considered as one of the most productive invertebratc fishing grounds worldwide. One of the most important exploited species is the scallop (Argopecten purpuratus) with strong catching fluctuations related to El Nino and La Nina events and to inadequate Management strategies. During strong warming periods annual landings reach up to 50000 t in an area of about 150 km**2 and during cold years they remain around 500 to 1000 t. This study analyses the changes in scallop landings at Independencia Bay observed during the last two decades and discusses the main factors affecting the scallop proliferations during the EI Nino events. In this way data on landings, sea surface temperature and those related to growth, reproduction, predation, mean density and oxygen concentration from published and unpublished Papers are used. The relationship between annual catches and average water temperature over the preceding reproductive period of the scallop over the past 20 year's period, showed that scallop production is affected positively only with strong EI Nino such as those of 1983 and 1998. Our review showed that the scallop stock proliferation can be traced to the combined effect of (1) an increase in reproductive output through an acceleration of gonad maturation and a higher spawning frequency; (2) a shortening of the larval period and an increase in larval survival; (3) an increase in the individual growth performance; (4) an increase in the juvenile and adult survival through reduction of predator biomass; (5) an increase in carrying capacity of the scallop banks due to elevated oxygen levels.

La organización de productores de El Maitén : una larga historia de intervención

En el presente trabajo se intenta reconstruir aspectos de la historia de un proceso organizativo de productores de la localidad de El Maitén e interpretar críticamente el proceso de intervención que lo acompañó. Durante el año 2004 fue creada la Agencia de Extensión Cooperativa integrada por el Municipio local, CORFO, INTA y la Subsecretaria de Agricultura Familiar, y fue en este marco institucional que se gestionó un proyecto de un parque de maquinarias de uso conjunto para los productores. Esta iniciativa demandó un proceso organizacional que hoy se sigue desarrollando. Para el análisis se realizo un recorte temporal que reconstruye, mediante metodología cualitativa y una perspectiva holística, la trayectoria organizativa del consorcio de maquinarias. A través de la voz de los protagonistas se desentrañan las idas y vueltas de la organización y de los modos de intervención institucional en el proceso.

Tipología de Replicaciones para la Síntesis de Experimentos en Ingeniería del Software

La Ingenieria del Software Experimental (ISE) traslada a la Ingenieria del Software (IS) el paradigma experimental que se ha aplicado con exito en diversas disciplinas cientificas. El objetivo de la ISE es hacer de la construccion del software una actividad predecible gracias al conocimiento de las relaciones entre los procesos de produccion del software y los productos que se obtienen. Para avanzar en el paradigma experimental en IS no es suficiente aplicar las tecnicas de diseno experimental y el analisis estadistico de datos, sino que es necesario construir una metodologia (bien desde cero o adaptada de otras disciplinas) basada en los principios generales del experimentalismo. La motivacion principal de esta investigacion es trabajar en la adaptacion de un aspecto particular del paradigma experimental a la experimentacion en IS: la replicación. En ISE se han realizado varias replicaciones de experimentos, sin embargo, aun existe discusion sobre el modo mas adecuado de llevarlas a cabo. Algunas preguntas que surgen de esta discusion son: .se deben reutilizar los materiales del experimento base?, .la replicacion debe realizarse de forma independiente, o puede existir algun tipo de comunicacion entre experimentadores y replicadores?, .que elementos de la estructura del experimento a replicar pueden variarse y aun considerarse una replicacion? En esta investigacion se estudia el concepto de replicacion desde una perspectiva teorico-practica para su incorporacion a la ISE. En concreto, se persiguen los siguientes objetivos: 1) estudio del concepto de replicacion en distintas disciplinas cientificas para tener mayor comprension de su importacion a la ISE, 2) desarrollo de una tipologia de replicaciones que ayude a comprender tanto los diferentes tipos de replicacion que pueden llevarse a cabo en ISE, asi como el papel que cada uno de estos tipos desempena en la verificacion de resultados experimentales y 3) desarrollo de un marco conceptual con ideas clave para comparar conjuntos de replicaciones y obtener conocimiento de ellas que sea de utilidad tanto para el profesional como para el investigador. Para la evaluacion de las propuestas de esta tesis se usa un conjunto de 20 replicaciones de diversos autores donde entre otros aspectos se evalua la efectividad de tres tecnicas de evaluacion de software.

Summer deficit irrigation in a hedgerow olive orchard cv. Arbequina: relationship between soil and tree water status, and growth and yield components

El potencial hídrico del tronco es una herramiento útil para el manejo del riego. Los umbrales de riego deben establecerse para cada periodo fisiológico. En este experimento, realizado en Arbequina en seto, se estudio la relacion entre los potenciales hídricos y la produccion de aceite. Cuando los potenciales hidricos son inferiores a -1.3 MPa el crecimiento vegetativo se reduce mas del 50%. En cuanto a la produccion, se observó que regando en Julio cuando se alcanzan potenciales cercanos a -2.9 MPa se puede ahorrar agua sin afectar a la produccion. Sin embargo en Agosto el potencial debe mantenerse por encima de -2 MPa para que no se resienta la producción.
