für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray La coneja presenta cualidades reproductivas particulares, entre otras, la ausencia de anestro lactacional por lo que puede quedar gestante poco después del parto. En la producción intensiva de esta especie esta característica es aprovechada a nivel productivo para que los intervalos entre partos sean lo más cortos posible, haciendo que se solapen la gestación y la lactación durante periodos prolongados de tiempo en contrapartida, ello exige unos requerimientos energéticos muy elevados. Este hecho resulta más problemático en las conejas primíparas lactantes, ya que, además, estos animales se encuentran en crecimiento y no son capaces de consumir suficiente cantidad de alimento para cubrir sus necesidades energéticas. Ello da lugar a un deterioro en su condición corporal, generando un descenso pronunciado de la fertilidad e importantes pérdidas económicas en la explotación. En este libro se proponen algunos mecanismos metabólicos y endocrinos que modulan la respuesta ovárica después del primer parto, para establecer pautas de manejo más efectivos compatibles con una mejor gestión de las reservas energéticas y, así, obtener resultados reproductivos más óptimos en la 2ª inseminación. ····· 1036190092

Se analizó el efecto estacional, se estimó el tiempo de renovación de aguas y balance de nutrientes. El análisis de distribución vertical de las variables y diagramas T-S, estipularon la presencia de 3 masas de agua en zona oceánica (0-400m profundidad): agua superficial Subantártica (ASAA), remanentes de agua Ecuatorial Subsuperficial y agua Intermedia Antártica. En zona de canales existió mezcla de ASAA con proporciones crecientes de agua dulce (ríos-lluvia-deshielo), generando Agua Subantártica Modificada y Agua Estuarina. Las aguas desde la zona central del Fiordo a su cabeza, presentó renovación media de 2 años, explicando en parte la baja de O2 en la zona profunda y hacia su salida la tasa fue de 6 meses. La capa superficial de los 2 subsistemas, presentaron fijación de N. En la capa profunda se presentó denitrificación, indicando un consumo de nitrato. El estado neto de los subsistemas fue diferente debido a la intensidad de los procesos en su interior. ····· 1036190069

La importancia de este animal radica en que es una especie que habita condiciones extremas, a altitudes que superan los 3500 m.s.n.m, donde incluso no existe ningún otro tipo de actividad agrícola o pecuario así como sus características fisiológicas que permiten cuidar el medio ambiente con miembros que no provocan erosión de suelos, con su peculiar hábito para arrancar superficialmente su alimento entre otros. En Bolivia se han identificado 2 ecotipos los del tipo Q ara y T amphulli,los primeros considerados más como productores de carne y el segundo como productor de fibra. Sin embargo en el presente estudio se pudo constatar que se puede obtener fibra muy fina de los animales del tipo Q ara. Actualmente el uso de la fibra de llama tiene cierta aceptación en el tejido de prendas de vestir, el cuero (curtido) es utilizado en la fabricación de sacones, chamarras, carteras, bolsas, calzados y una variedad de artesanía. Mientras que la carne de llama tiene gran demanda en algunos sectores del país, consumiéndose en fresco y/o deshidratado - salado (charki). ····· 1036189805

Se evaluó la percepción que los componentes de la localidad, tenían sobre la actividad de buceo, problemática ambiental y turismo. Se efectuaron observaciones al coral (método Aggra), para establecer si existían hechos asociados al buceo que pudiesen estar generando alteraciones en la calidad ambiental del área. Resultados indicaron que esta actividad recreativa tiene, en el área, una alta percepción entre las personas que lo practican, percibiendo que los pobladores pueden resultar beneficiados de la misma. Sin embargo, este mismo grupo indica que los pobladores presentan una relativa percepción negativa hacia la práctica de este deporte. Resultados de las observaciones muestran que la práctica del buceo, de forma no controlada, sumado a los efectos ambientales adversos en el área puede hacerlo ambientalmente no sostenible. Se proponen aspectos técnicos que puedan ser viables y generar una práctica sostenible de esta actividad y aplicar a otras localidades similares en Venezuela ····· 1036189600

No obstante la concentración en planta de estos compuestos normalmente es muy baja, inviabilizando su aprovechamiento comercial a partir de la planta completa. La tecnología del cultivo de células vegetales provee una alternativa viable al cultivo de la planta completa para la producción de metabolitos de interés económico. Las condiciones ambientales en los cultivos in vitro de células vegetales pueden ser controladas y manipuladas permitiendo a las células crecer y proliferar a ratas más altas que en las plantas completas. Algunos metabolitos también se acumulan en concentraciones más altas en las células cultivadas que en las plantas originales. Por adecuada manipulación de las condiciones del cultivo, el uso de precursores/elicitores y el cultivo en biorreactores diseñados adecuadamente, es posible alcanzar altas concentraciones y productividades del compuesto de interés.

Storage places in the house are the most important places for every workstation where required items for work performance are stored.Limited space available for human beings leads to the alteration of behavioral patterns and attitudes of the users of the space and eventually causes stress and strain. Adequate and well designed houses not only protect people against health hazards but also help to promote good health, economic productivity, psychological well being and social vigor. Desirable sequence of work cannot be maintained without the provision of adequate storage spaces. Due to faulty storage structure in the house many homemakers suffers from various types of biomechanical problems such as curved back, hunched shoulders and distorted legs and feet. The major causative factors responsible for biomechanical pain are the static muscular effort and unnatural body postures made by women while using the faulty storage structure. ····· 1036189052

In the pastoral and agro-pastoral areas, natural pasture land or grazing land is a main source of feed for the livestock. However, a large portion of the grassland had been changed into other land cover forms, mainly to cultivated fields and woodland. Moreover, vegetation resources have degraded both in quantity and quality as a consequence of decreased in grass vegetation cover through over-grazing and cultivation. Due to over grazing and over utilization, these areas have been exposed to soil erosion and soil compaction. In general, the land use/land cover changes and the declining of rangeland vegetation quality and quantity through time and space are result of demographic expansion, mainly increasing population and livestock numbers, recurrent droughts, lack of technologies that suit the socio-economic and natural conditions, and natural resources policy. The conversion of natural ecosystems into managed agro-ecosystems resulted in deterioration in quality of the soil resource base. ····· 1036187352
