waterlogging is one of the problems of cotton-growing in rainy regions which affects adversely plant growth in the early stages. so that rainfall causes waterlogging in early to mid spring in the fields without proper drainage. also, rainfall declines soil and environment temperatures. to investigate the effects of waterlogging period duration and temperature on vegetative properties and glycol...

Valeriana officinalis L. (Valerianaceae) is one of the most widely used plants for the treatment of anxiety and insomnia. Usually dry plant extracts, including V. officinalis, are hygroscopic materials with poor physico-mechanical properties that can be directly compressed.A V. officinalis dry extract with moderate hygroscocity is suitable for direct compression, and was obtained by using a sim...

To assess the ability of the nose to warm and humidify inhaled air, we developed a nasopharyngeal probe and measured the temperature and humidity of air exiting the nasal cavity. We delivered cold, dry air (19-1 degrees C, <10% relative humidity) or hot, humid air (37 degrees C, >90% relative humidity) to the nose via a nasal mask at flow rates of 5, 10, and 20 l/min. We used a water gradient a...

The atmospheric range error in an electromagnetic signal arriving vertically at the earth is measured by the height integral of the refractivity N through the atmosphere. (N = 10^ (n-1) where n is the index of refraction.) N in the non-ionized atmosphere is the sum of "dry" and "wet" components, which are considered separately. Only the dry part is important at optical wavelengths,and the prese...

PURPOSE To investigate the effect of exposure to a low relative humidity (RH) environment on tear film physiology. METHOD A controlled environment chamber was used to create 2 different environmental conditions. Ambient temperature was constant in both conditions (21°C) while the RH was set at 40% at the normal condition and at 5% in the desiccating environment. Tear evaporation, noninvasive ...

The change in climate has led to an interest in how this will affect the energy consumption in buildings. Most of the work in the literature relates to offices and homes. However, this paper investigates a supermarket in northern England by means of a multiple regression analysis based on gas and electricity data for 2012. The equations obtained in this analysis use the humidity ratio derived f...
