Foram obtidos dois produtos de banana por desidratação osmótica, um sob pressão atmosférica e outro sob vácuo, com complemento de secagem em estufa. A estabilidade dos produtos foi estudada, durante 120 dias, mediante análises físico-químicas, microbiológicas e sensoriais. Nesse período, os produtos ficaram armazenados em temperatura ambiente (23,4-34,1oC) e umidade relativa entre 33-81%. Concluiu-se que os produtos mantiveram suas características químicas, físico-químicas e sensoriais, além de estabilidade microbiológica (pouca variação durante o período de armazenamento). Somente a cor dos produtos apresentou variação expressiva. Sugere-se o tratamento utilizando osmose com vácuo seguido de secagem para produção de banana passa. EVALUATION OF PRODUCTS OBTAINED BY THE BANANA’S OSMOTIC DEHYDRATION FOLLOWED OF DRYING Abstract It was obtained two bananas products through osmotic dehydration, one under atmospheric pressure and other under vacuum, with drying complement in stove. The storage stability of these products was studied, during 120 days, through physicalchemical, microbiological and sensorial analysis. In this period, the products were stored at room temperature (23,4-34,1oC) and relative humidity between 33-81%. It was concluded that the obtained products maintained their chemical, physico-chemical and sensory characteristics, beyond microbiological stability (small variations during the storage period). Only the color of the produtcs presented more expressive variations. Therefore it is suggested the treatment using osmosis with vacuum followed by oven drying for the production of banana fig.

Modified Method

A modified typical meteorological year (TMY) method is proposed for generating TMY from practical measured weather data. A total of eleven weather indices and novel assigned weighting factors are applied in the processing of forming the TMY database. TMYs of 35 cities in China are generated based on the latest and accurate measured weather data (dry bulb temperature, relative humidity, wind velocity, atmospheric pressure, and daily global solar radiation) in the period of 1994–2010. The TMY data and typical solar radiation data are also investigated and analyzed in this paper, which are important in the utilizations of solar energy systems.

Diurnal Behavior

Studies in the region of Baie Comeau, Quebec, from 1954 to 1956, showed that black flies were most active in the morning 1 to 2 hours after dawn and in the evening [Formula: see text] to 1 hour before sunset. Flight activity appeared to depend on light intensity if the temperature was not below 45° F, the wind velocity not above 2 m.p.h., and the relative humidity not below 50%. In the morning, activity was greatest at higher levels of light intensity, i.e., 20 ft-c, than in the evening, 5 ft-c. Activity increased before thunderstorms and rain and the increase appeared related more to the change in light intensity than to changes in atmospheric pressure or humidity. At night, black flies moved to resting places in the tops of the trees, probably because of the more suitable light intensity at the higher levels just before dark. Oviposition commenced in the late afternoon and continued until dark except on overcast days, when it commenced in early afternoon. Simulium (Simulium) venustum Say bit man mainly on the back of the neck.

Transfer Standard

AbstractCigarette draw resistance and filter pressure drop (PD) are both major physical parameters for the tobacco industry. Therefore these parameters must be measured reliably. For these measurements, specific equipment calibrated with PD transfer standards is used. Each transfer standard must have a known and stable PD value, such standards usually being composed of several capillary tubes associated in parallel. However, PD values are modified by ambient conditions during calibration of such standards, i.e. by temperature and relative humidity (RH) of air, and atmospheric pressure. In order to reduce the influence of these ambient factors, a simplified model was developed for compensating the effects of ambient conditions on the calibration of multi-capillary PD standards.
