Given the importance ornamental that presents the areca palm (Dypsis lutescens. H. Wendel) in our country, this paper was developed at the National Institute of Agricultural Sciences (INCA) in order to find alternatives for the conservation of seeds of this species, to increase the period of viability. A study of conservation of seeds in the period from September to February, in the years 2009 and 2010, using different containers (black plastic bags, cloth bags and plastic containers) and two storage conditions (temperature and fourth air-conditioned). The percentage of germination was assessed for that month and seeds were removed and placed to germinate in petri dishes, randomly distributed, with six replicates per treatment, 15 seeds were used on each plate. It also determined the percentage of moisture in each assessment. The result was that for both years the best germination percentages were found in seeds kept in nylon bags, reaching up to 50 % in 2009 and 80 % in 2010, 90 days after the conserved seeds, not so for the rest of the treatments, where germination was almost zero after two and three months of storage, reaching values of 10 and 25 %. In relation to the percentage of moisture, the seeds preserved in hermetically sealed containers had the highest values, whereas those stored in cloth bags, exhibited the lowest percentages in both study periods.

Monitoring and control of the microbiological quality of the air is very important for human activity, which is why aeromicrobiology has boomed in recent years. Specialists suggest that to study the airborne of indoor and outdoor environments, numerous factors must be taken into account such as temperature, relative humidity, the time of year and even the time of the study, however, they forget that microorganisms are charged bioparticles and ignore the presence of an extremely low frequency oscillating magnetic field (ELF-OMF) at the time of air sampling. For this reason, the aim of this paper was to analyze the bibliographic sources that support the considerations about the influence of the ELF-OMF on the indoor airborne of indoor environments. The accepted scientific knowledge in microbiology on the effect of ionizing radiation on the excretion of pigments by the fungi and the electrical charge of microorganisms was linked to the experimental results of the electromagnetic attraction suffered by the same and the dust particles and ions in the air to which they may be united. Based on the link made, was supported that the ELF-OMF influences on the indoor indoor airborne, so it should be seen as a physical factor for the microbiological samplings of indoor air.

The aim of this paper was to evaluate the effects of a strategy of changes to manage the bio-economic efficiency of a Murrah Buffalo production system in the province of Camagüey, Cuba, located 210 north and 770 west, 217 meters above sea level. The climate is tropical humid (Aw) plain. The mean annual precipitations average 1 180 mm (71 % between May and October), and temperature is between 24 and 29° C. The local soil is carbonated brown, brown without carbonates, and reddish-brown fersiallitic. The system comprises 5 100 ha and has 536 workers/year. A strategy to introduce management changes in agro-technology, food, reproduction, replacement, health, salary policies, and training was implemented as part of an innovation package with a systemic and participatory approach. The evaluation lasted eight years, and it was critical to increase dairy production in more than 200 000 kg/year in 2012, in comparison to 2004, with improvements in natality and reduction of operational expenses of the system. It was concluded that the strategy had a determining effect on the system's indicators. [ABSTRACT FROM AUTHOR]

Introduction- The use of composites made of vegetable origin materials has gained importance in some areas of engineering, mainly in civil construction. Objective- The objective of this paper is to analyze the physical and mechanical behavior of panels made with caña brava fibers and vegetal resin. Methodology- For the elaboration of the panels, the fibers were extracted using a mechanical crusher. The fibers were treated with a sodium hydroxide solution. The effect of the chemical treatment was evaluated by scanning electron microscopy. The roughness of the fibers was determined using the atomic force microscopy technique. For the manufacture of the composite, a compression method was used. The physical characterization of the panels was focused on the evaluation of the effective absorption, density, and percentage of swelling. To evaluate the mechanical behavior, static bending and mechanical fracture tests were performed. To evaluate the degradation of the material with the temperature, a thermogravimetric test was executed. Results- From the results, it is possible to verify that panels made with caña brava fibers and vegetal resin can present an increase in their dimensional stability when compared to panels made with Guadua Angustifolia Kunth fibers and show higher values of strength and stiffness than panels elaborated with coconut and bamboo fibers. Conclusions- Considering that caña brava is an invasive plant, its application as reinforcement of composite panels is a viable option to promote the development and application of new materials in civil construction.

The aim of this paper is to estimate the temporal of turnover pattern of moths species in relation to two environmental gradients: temperature (° C) and relative humidity(%). Using a light trap method, a community of moths were sampled for a period of 12 months, in the Kaxil Kiuic Biocultural Reserve located in Yucatán, Mexico. It was demonstrated that species turnover exhibits a strong temporal pattern in relation to temperature and relative humidity variation between climatic periods. The warm and dry period (March to July) had the highest dissimilarity in species composition, determined mainly by families: Noctuidae, Geometridae and Crambidae. This study provides information on the temporal pattern of temporal species turnover for families with high species richness of Neotropical moths. The results obtained have implications for conservation of moth biodiversity, since they allow a base line to be established, focused on detecting the effects of climatic variations on species composition.

This paper was aimed to determine the adsorption isotherm of pound cake at 30°C. Critical equilibrium relative humidity and critical humidity content were sensory determined. Water activity and humidity content equilibrium were fitted to the G.A.B. model, via regression analysis. The isotherm showed a good fit to the G. A.B. model. Critical water activity value of layer cake at it was sensory and microbiological accepted was 0.842. [ABSTRACT FROM AUTHOR]

In this paper a calculation method is presented to determine with accuracy the time that a dehumidifier should work to reach the required minimum humidity and it is compared with the calculation presented in the traditional literature. In the proposed method calculation, the efficiency is used as fundamental economic indicator of the dehumidification process. [ABSTRACT FROM AUTHOR]

In this paper the mechanisms of humidity transport are explained. These mechanisms have place in underground warehouses according to the climatic and geohydrological characteristics of Cuba. An analogy with the Fick's law is stated and it intends a theoretical model that describes this mechanism of transport toward the cavities. It was determined the local coefficients of transport of humidity experimentally for different recover types in walls and different geometric forms of the warehouses. [ABSTRACT FROM AUTHOR]

In this paper the methodology for calculating of useful life time of cylindrical founding core during its permanence in outdoor moisture, in the time intervals from instant in which they are made to laundry moment, is described. The problem of calculation the limiting time was solved by the moisture diffusion process analysis in these media. The functional dependence of limiting time with both radial dimensions of cylindrical core and the effective diffusion coefficient of the atmospheric water in the mixture, that was used for conforming the core, was found. The dependence of limiting time with both the percent increase in the equilibrium humid mass, the percent increase in the critical humid mass and the environmental moisture was found too.

Convective activity prediction in the tropics are still an unsolved problem. Difficulties are mainly related to the fact the phenomenum, very often results as a complex interaction between local and large scale stream conditions. Days with thunderstorm activity compared with surface and height data for 10 years are presented in this paper in order to determine both, large and local scale conditions that propitiate the developing of convective activity in the Bogota sabana. As a main result it is shown that at the 700 hPa isobaric surface, electrical storms appears whit weale winds and high contents of humidity, which characterize the alisios convergence zone and also the ecuatorial ascendent branch of the Hadley cell. Besides, the analysis shows that local thermal convection strengthened by orograhapic effect are the trigger mechanism for electrical storm in the "Sabana de Bogota". These conclusions explain the origin and develop of the phenomenum and allow to give some recomendations for its diagnostic and forecasting. Finally an circulation model during the developing of convective activity in the "Sabana de Bogota". [ABSTRACT FROM AUTHOR]

Mastichodendron foetidissimum (Jacq.) Cronq. is a tree characterized by heteromorphic seeds, which differ greatly in shape and size as a result of their number (1, 2 or 3) in each fruit. In this paper the correlation between this variability and the germinative response of the seeds was determined. The seeds were classified into three categories, according to their shape (morphs I, II and III), corresponding to the number of seeds per fruit. For each morph, length, width, thickness, fresh weight, dry weight, content of humidity and percent of germination were determined. All the parameters differ between morphs, except the humidity content. The morphological variability shows a clear correlation with the germinative response: the heavier seeds (morph I) display the larger percentages of germination. [ABSTRACT FROM AUTHOR]

The aim of this work was to find a model which allows predicting the drying time of mango (Mangifera indica) pulp at different temperature conditions. A laboratory dryer was built in which several drying probes at 55 °C, 60 °C, and 65 °C took place, with a constant air velocity of 2,0 m/s and a 50% controlled relative humidity. A simple procedure to convert GAB model to a second order polynomial equation is shown. Also, it is shown a simple manner to establish process drying kinetics that could be applied to similar processes from simplified models of the classical Fick's equation. [ABSTRACT FROM AUTHOR]
