Analysis of the Atmosphere Aerosol and Ozone Condition Over Tbilisi Using Satellite Data and Ground Truth Measurements

Ground-based measurements of the parameters of atmosphere in Tbilisi during the same period, which are provided by the Mikheil Nodia Institute of geophysics, were used as calibration data. Satellite data monthly averaging, preprocessing, analysis and visualization was performed using Giovanni web-based application. Maps of trends and periodic components of the atmosphere aerosol optical thickness and ozone concentration over the study area were calculated.

Pressao arterial elevada em criancas e sua correlacao com tres definicoes de obesidade infantil

FUNDAMENTO: Diversos autores correlacionaram o aumento do risco cardiovascular com o estado nutricional, porém existem diferentes critérios para a classificação de sobrepeso e obesidade em crianças. Objetivos: Avaliar o desempenho de três critérios de classificação nutricional em crianças, como definidores da presença de obesidade e preditores de níveis pressóricos elevados em escolares. MÉTODOS: Oitocentas e dezessete crianças de 6 a 13 anos matriculadas em escolas públicas do município de Vila Velha (ES) foram submetidas a avaliação antropométrica e de pressão arterial. A classificação quanto ao estado nutricional foi estabelecida mediante dois critérios internacionais (CDC/NCHS 2000 e IOTF 2000) e um critério brasileiro (Conde e Monteiro 2006). RESULTADOS: A prevalência de excesso de peso foi maior quando utilizado o critério de Conde e Monteiro (27%), e menor pelo critério do IOTF (15%). Pressão arterial elevada foi observada em 7,3% das crianças. Identificou-se forte associação entre a presença de excesso de peso e a ocorrência de níveis pressóricos elevados, independentemente do critério utilizado (p < 0,001). O critério que demonstrou maior sensibilidade em prever PA elevada foi o de Conde e Monteiro (44%), enquanto o de maior especificidade (94%), além de maior acurácia geral (63%), foi o do CDC. CONCLUSÕES: A prevalência de excesso de peso em crianças brasileiras é maior quando utilizado o critério de classificação de Conde e Monteiro, e menor quando utilizado o critério do IOTF. O critério de classificação brasileiro demonstrou ser o mais sensível como preditor de risco de PA elevada nessa amostra.

Development of Anatomophysiologic Knowledge Regarding the Cardiovascular System: From Egyptians to Harvey

Our knowledge regarding the anatomophysiology of the cardiovascular system (CVS) has progressed since the fourth millennium BC. In Egypt (3500 BC), it was believed that a set of channels are interconnected to the heart, transporting air, urine, air, blood, and the soul. One thousand years later, the heart was established as the center of the CVS by the Hippocratic Corpus in the medical school of Kos, and some of the CVS anatomical characteristics were defined. The CVS was known to transport blood via the right ventricle through veins and the pneuma via the left ventricle through arteries. Two hundred years later, in Alexandria, following the development of human anatomical dissection, Herophilus discovered that arteries were 6 times thicker than veins, and Erasistratus described the semilunar valves, emphasizing that arteries were filled with blood when ventricles were empty. Further, 200 years later, Galen demonstrated that arteries contained blood and not air. With the decline of the Roman Empire, Greco-Roman medical knowledge about the CVS was preserved in Persia, and later in Islam where, Ibn Nafis inaccurately described pulmonary circulation. The resurgence of dissection of the human body in Europe in the 14th century was associated with the revival of the knowledge pertaining to the CVS. The main findings were the description of pulmonary circulation by Servetus, the anatomical discoveries of Vesalius, the demonstration of pulmonary circulation by Colombo, and the discovery of valves in veins by Fabricius. Following these developments, Harvey described blood circulation.

Fatôres que afetam a determinação da vitamina C na goiaba (Psidium guajava L.)

In the present paper the authors deal with the content of ascorbic acid in guavas (Psidium guajava L.) and the methods of sampling used. Ascorbic acid was determined directly in the photoeletric colorimeter (EEL), after extraction with a 4 per cent solution of oxalic acid. Guavas from various parts of State of S.Paulo were used and the general mean found was around 100 mgm of ascorbic acid per 100 gm fresh weight of the material used for extraction. It was found that there is great variation in the ascorbic acid content according to the condition of the fruit: Ascorbic acid Condition content in Mean mgm/100 gm Green and hard 93,36 - 119,54 102,43 Small green 57,34 - 92,30 83,40 Firm ripe 71,28 - 115,98 90,32 Overripe 63,22 - 85,98 77,36 Of the diferent parts of the fruit, the skin has the highest content; the pulp between the skin and the parts containing the seeds, the "inner pulp" contains little and finallw the central parts, formed by the pulp between seeds, the "inter pulp" a engligible amount. The proportion of ascorbic acid found in the skin, inner pulp and inter pulp may be as high as 1.6: 1: 0. Furthermore, the section near the peduncule and the sepals are richer than equatorial crossections. It was proved that the amount and intensity of sun-light is at least one important factant factor determining differences in the ascorbic acid content of the fruit, which is higer in the parts which have received more light. A sharp decrease was found in the vitamin C content of ripe fruite stored in a home refrigerator. The periods of the preservation were 12-24-48-96 hours and the decrease of the ascorbic acid content m per cent was 23.4 - 42.0 - 66.8 - 76.4 of the initial content of 144.28 mgm/100 gm. The following five different methods of sampling in the determination of the amount of vitamin C were tested, with extraction in a Waring blendor: 1) whole fruit; 2,) sample taken form fruits cut into many small pieces; 3) half of a fruit divided by a crossection at equal distance from both ends; 4) half of fruit divided lenghtwise; 5) a transversal slice of about 1 cm. It was found that the two first methods geve the most reliable results.
