The thermocouple is used for obtaining the air temperature with sensitivity and optimum precision, beyond great advantage over the mercury or alcohol thermometer, because it generates electrical signals that can be stored in automated systems. However, when it comes to obtaining the relative humidity from thermocouple, it is needed caution due to other factors involved. In this study two sets of thermocouple psychrometers, aspirated and no-aspirated were evaluated, relative to a Vaisala set, from 17 to 31/01/2008 (15 days). From measurements of dry and wet bulb temperatures, the relative humidity value was obtained, and it was possible to compare them with the Vaisala set measurements. The two types of psychrometers showed precision and accuracy in measurements of air temperature, and only precision in measurements of relative humidity, being that the aspirated psychrometer presented more precision. Despite the no-aspirated psychrometer has lesser precision in measurements, it is more robust because it is independent of a 12 VDC micro-fan, making it, a sensor with lesser risk of inadequate measures. Both aspirated and no-aspirated psychrometers do not measure accurately the relative air humidity during night period.

The sun has an extremely important role in the existence of human beings, and Brazil has a privileged geographical position to explore sunlight. The union of these two factors favors the use of solar cells for converting solar energy into electricity by photovoltaic technology: it is a great alternative energy source, especially for being a clean one, causing less damage to the environment. This paper addresses the photovoltaic technology with a focus on hospitals, through case studies found in international literature, because hospitals, even running all important services to society, have a potential for pollution capable of causing damage to human health and the environment that is around them. It is estimated that the Brazilian oil reserves are sufficient for twenty-two years. This makes the search for alternative sources for power generation a necessity.

A presente invenção se refere à síntese e caracterização de complexos fosfínicos de rutênio (II) contendo o íon picolinato e/ou dilminas e/ou bifosfinas com ótima atividade farmacológica na inibição do crescimento da micobactéria da tuberculose. Tais complexos poderão primeiramente ser utilizados na indústria química e a médio e longo prazo na indústria farmacêutica. A presente invenção descreve também como foi realizada a determinação da atividade contra o bacilo da tuberculose, bem como avalia a toxicidade dos complexos contra as células de macrófagos onde o bacilo da tuberculose se internalíza.
