Efecto del cloruro de calcio sobre láminas de mango ( Mangifera indica check for this species in other resources L.) variedad Keitt deshidratadas osmóticamente por pulso de vacÃo
The objective was to evaluate the inclusion of calcium chloride on slices of osmotically dehydrated mango variety Keitt applying cycles of vacuum pulse of 23 inHg for a duration of five minutes for eight hours at room temperature in solutions prepared with 65% sucrose, 0.2% of ascorbic acid and percentage concentrations of the mentioned salt of 0.5; 1.5 y 2.5 being the control 0%. The samples were kept immersed in the solutions to reach osmotic equilibrium at 24 hours and the values of water activity (Aw) were determined with values of 0.9191, 0.9053, 0.9179 and 0.9029, respectively. It was found that the higher the concentration of calcium chloride, the Aw was more reduced, moisture loss was larger and the weight reduction occurred more rapidly.El objetivo fue evaluar la inclusión de cloruro de calcio en láminas de mango variedad Keitt deshidratadas osmóticamente aplicando ciclos de pulso de vacÃo de 584,2 mmHg con una duración de 5 minutos durante 8 horas a temperatura ambiente, en soluciones preparadas con 65% de sacarosa, 0,2% de ácido ascórbico y concentraciones porcentuales de la sal mencionada de 0,5; 1,5 y 2,5), denominándose el blanco To. Las muestras permanecieron sumergidas en las soluciones hasta alcanzar el equilibrio osmótico a las 24 horas y se determinaron los valores de actividad de agua (Aw) de 0,9191; 0,9179 0,9053 y 0,9029, respectivamente. Se obtuvo que a mayor concentración de cloruro de calcio, mayor es la reducción de Aw y mayor la pérdida de humedad y la reducción del peso ocurre con mayor rapidez
Propuesta para la creación del Departamento de Extensión Agropecuaria del Núcleo Monagas de la Universidad de Oriente (Proposal for the creation of the Departamento de Extensión Agropecuaria (Agricultural Extension Department) of Núcleo Monagas of The Universidad de Oriente)
The agricultural extension service plays an important role in the
attainment of desirable changes in the rural environment, guiding the
family capacities and making them participants of its own social,
economic and technological development for improving its life quality
in the context of a sustainable agriculture. It is for this reason that
the requirement of the creation of the Department of Agricultural
Extension Service of the Universidad de Oriente arises, which will
allow to link science and technology to the real context of the
agricultural production, in the search of integral solutions, in
agreement with the necessities and priorities of farmers of the area,
promoting changes in its knowledge, attitudes, skills and wishes, for
improving its welfare and of the population in general. Among the
principal objectives of the Department they will be: to carry out
diagnoses of the principal agriculture-social-economic problems of the
inhabitants of the rural communities of the Monagas state and to
develop action strategies that, by means of integral and sustainable
solutions and with the community participation, to have a worthy of
life for the farmers of the region. The area of influence of the
Department of Agricultural Extension Service will be framed initially
in the 13 Municipalities of the Monagas state and in the bordering
communities with other neighboring states, but later on, the action
range will be able to go toward communities belonging to all the states
of the Venezuelan East where Universidad de Oriente has influence.
Among the benefits that the creation of the Department of Agricultural
Extension Service will give to Universidad de Oriente they are:
diffusion and popularization of the research carried out by the
educational and research personnel staff members of University; regain
of the presence of the Universidad de Oriente in the agricultural
environment of the Oriental area of Venezuela; training and formation
of the educational personnel staff in programs of agricultural
extension; to achieve an increment of the in situ practical activities;
to carry out activities that allow to improve the life quality of
farmers of the area of influence of the Universidad de Oriente and to
advise agricultural extension works at level of higher education. The
personnel staff of this Department will be integrated for: A Head of
Department of Agricultural Extension Service; a Coordinator of
Agricultural Extension Service for each School (three in total); an
Agent of Agricultural Extension for each School (three in total);
responsible for programs or projects (the professors of the three
Schools) and a secretary. Besides the Universidad de Oriente, in the
Department of Agricultural Extension Service could be wrapped other
Institutions of public character as private (Polar Foundation, CIARA,
IICA, Government and Municipalities of Monagas State; INIA, MAT, CVG,
EUDOCA, FONACIT, FAO, Associations of Farmers, etc.). The financing to
cover the costs of opening of the Department of Agricultural Extension
Service, personnel staff payment and operational costs will be mainly
in charge of the Universidad de Oriente, but other Institutions like
the Governments and Municipalities of the Oriental States, Associations
of Farmers and enterprise like: PDVSA, Polar Foundation, Bigott
Foundation, Foninpal, FONDAFA, etc., and International Organisms as:
the World Bank, IICA, SIHCA, FAO, BID, UNICEF, ONGs, Embassies, etc,
they could help financially to the Department of Agricultural Extension
Service of Universidad de Oriente through the execution of projects
