Estrutura térmica de cidades de pequeno e médio porte do interior paulista (1961-2009)

The climate is one of the main elements of the natural environment that governs the life of man. Specific conditions of temperature, humidity, light, wind and precipitation have direct influence on physiological conditions that man needs to survive and more than that, besides the influence on human and animal physiology, the climatic elements are also responsible for a significant portion of economic activities such as industry, agriculture, commerce, transportation, and others. Therefore, any change in weather patterns has great impact on daily activities, and even more in urban sites, where the most of population is concentrated nowadays. Based on this discussion and concerned in understand the atmospheric structure, this monograph intends to analyze the pattern of atmospheric and temperature element in seven cities of small and medium size located in the state of São Paulo countryside...

Estudo e caracterização térmica da curcumina e de uma forma polimórfica

This paper was prepared a polymorphic from of curcumin a natural bioactive compound widely used in Indian medicine in the treatment of a range of illnesses. The preparation was the polymorphic crystallization process and solvent mixtures of organic solvents in order to change the dielectric constant of the solution to obtain crystals. The crystal of curcumin has been studied and characterized by absorption spectroscopic in the infrared, X-ray diffraction powder method and by thermo analytical techniques: thermogravimetry and differential therma analysis (TG-DTA) and differential scanning calorimetry (DSC). The DSC of the pure compound (MP=180,19ºC) showed some differences compared the compound crystallized (MP=176.63ºC) in a mixture of solvents thus indicating the phenomenon of polymorphism, and TG-DTA curve of the compound crystallized showed that this was not a solvatomorphic. Finnally the techniques of X-ray diffraction technique FTIR and powder showed a structural change in the compound crystallized, profile-based graphics when compared to the pure compound, which proves that the compound crystallized it is a polymorph

Comparação da eficiência térmica de trocadores de calor no laboratório de sistemas térmicos da Faculdade de Engenharia

This work aims to verify and compare the efficiency of heat exchangers used in the thermal systems laboratory at Faculdade de Engenharia do Campus de Guaratinguetá - UNESP. Basically, it has been studied two types of heat exchangers: plate type, operating in parallel flow and counter-flow, shell and tube type and also operating in parallel flow and counter flow. Initially it has been presented the didactic equipment and procedures for use of these heat exchangers in the proposed experiments. With the results obtained from the experiments, comparisons were made in order to define the behavior of the heat exchangers regarding some variables. In the study, one comes to the conclusion that the results from shell and tube type of heat exchanger, used in the thermal systems lab, are superior in all conditions analyzed

Síndrome dilatação-vólvulo gástrico em cães

The gastric dilatation- volvulus (GDV) is an acute and potentially lethal disease, characterized by increased size of the stomach associated with mesenteric rotation on its axis, which affects mainly large breed dogs and giants with deep and narrow chest. The diagnosis is made from the history, physical examination, clinical signs and radiographic evaluation. It is an emergency that requires immediate therapy and consists on protocols to treat shock, gastric decompression, surgical repositioning of the stomach, gastropexy and intensive post-operative care. Despite the significant progress in the elucidation of pathophysiological events, risk factors and treatment, there was almost no progress in determining the root causes of this disease. A significant advance was recently described in the literature on this topic is the technique of gastropexy laparoscopy. Instruct the owners of the high risk breeds is extremely important to avoid situations in which the severity of the illness make the surgical treatment impracticable and the animal’s condition irreversible

Comparando a eficácia da manta térmica com método de aquecimento passivo na prevenção de hipotermia

Hypothermia is a common phenomenon in the perioperative period, and it affects 60 to 90% of patients submitted to anesthetic-surgical procedures. In order to minimize its incidence, warming methods are used. Such methods can be passive, such as orthopedic cotton, sheets and blankets, or active, such as warm-air blankets and thermal mattresses. In this scenario, the present study aimed at comparing two warming methods used in the intraoperative period. Patients submitted to abdominal surgery in the specialties of gynecology and gastric surgery from August to September 2010 were included in the study. After randomization, they were divided into two groups: one using a thermal blanket (group I) and one using orthopedic cotton (group II). At last, 9 patients were included. The variables for each question were considered according to occurrence frequency. Comparison between groups was performed by Student’s t test. With the purpose to analyze whether there was an association, the chi-square test or Fisher’s Exact test was used. Whenever it was applicable for multiple comparisons, Tukey’s test was utilized; p values < 0.05 were considered to be statistically significant for analysis. The sample comprised 6 males and 3 females submitted to gynecological and gastric surgeries. Their mean age was 48 years for group I and 46.2 years for group II. A predominance of general anesthesia was observed. The time of permanence in the operating room ranged from 80 to 360 minutes. With regard to warming parenteral solutions, the procedure was performed on 5 patients, and infusion of warm solution into the abdominal cavity was performed on 50% of the sample. Concerning the warming method used, 5 patients used a thermal blanket. In view of the results presented, it was not possible to conclude which warming method should be used due to sample size

Desenvolvimento e caracterização térmica de sistemas líquido-cristalinos contendo ácido kójico

O Ácido Kójico (AK) é uma substancia produzida por cepas de Aspergillus sp. Foi isolado pela primeira vez em 1907, através do estudo feito a partir do crescimento desse fungo em arroz cozido a vapor. É usado na cosmetologia como antioxidante e despigmentante para uso tópico. Atua como um potente antioxidante quelando íons de ferro e os íons de cobre presentes no seu sítio ativo da tirosinase impedindo a formação de melanina. O isononanoato de cetoestearila, utilizado na formulação, tem ampla utilização em cosméticos como cremes protetores de epiderme, cremes de maquiagens, cremes de proteção solar, loções e desodorantes por ser emoliente, não possuir cheiro e toque seco. Os sistemas nanoestruturados, como por exemplo, os sistemas líquidocristalinos aumentam a solubilidade dos princípios ativos incorporados ao sistema e aumentam a solubilidade dos princípios ativos incorporados ao sistema e aumentam a estabilidade e diminuem a toxidade, pois agem como reservatórios e dependendo da interação fármaco-sistema, altera a biodisponibilidade. O presente trabalho tem como objetivo desenvolver e caracterizar um sistema líquido cristalino constituído por água e isononanoato de cetoestearila (óleo), e estabilizado com o tensoativo álcool cetílico etoxilado e propoxilado contendo ácido kójico avaliando sua estabilidade através de estudos de termoanálises
