This work presents the evaluation of the thermal sensitivity index and global radiation during the total eclipse of the sun on November 12th, 1966, in the city of Bagé, RS, Brazil, located in the central line of the totality range of the eclipse. Temperature (oC), relative air humidity (%), cloudiness and wind speed were acquired in the international airport of the city for the calculation of the resultant temperature index by using Missenard’s method (1948). Global radiation data was obtained from Eppley spectral radiometer. The results showed a variation in thermal sensation, due to the decreased global radiation and corresponding decreased temperature and increased relative humidity during the eclipse.

A 16-Page pamphlet which has been prepared at Burnley Grammar School and published there at the price of 6d. under the title Guide to the Eclipse of June 29th, 1927, fits into the gap between the instructions of the professional astronomer and the advice of the professional journalist. Of the five sections—the cause, what to look for, hints to photographers, the eclipse in history, an expedition which “failed”—perhaps it is the third which is the most important; the last section, a quotation from Piazzi Smyth’s account of the terrestrial effects of totality when the sun itself is clouded, is a valuable antidote when meteorological friends have operated with their usual depression and we feel that the chance of a fine morning would hardly justify us in getting up early even if we lived on the central line.

O objetivo desta pesquisa foi avaliar as variáveis microclimáticas, percepção e sensação térmica urbana de habitantes de um residencial planejado para famílias de baixa renda, na cidade de Santarém- Pará. Foi coletado dados de temperatura, umidade relativa do ar e velocidade do vento, além de aplicações de formulários pré-estabelecidos. O experimento ocorreu no dia 15 de agosto de 2018, em um transecto com sete pontos no residencial. Foram aplicados formulários em área interna (casas) e externa no total de 115 formulários, para uma população com idade de 15 a 60 anos. Com as informações microclimáticas do local foram calculados os índices de Temperatura e Umidade, de Temperatura e Umidade modificado e Temperatura Efetiva em função do Vento, os quais foram correlacionados com as sensações subjetivas da população do local. Os resultados indicam que o índice de Temperatura Efetiva em função do Vento foi o mais compatível com a sensação e a percepção pessoal dos entrevistados. Ficou bem evidente o desconforto térmico sentido pela população, entre o período de 12 a 15 h na área externa e 15 a 18 h na área interna (casas). A temperatura de brilho no recorte do residencial Salvação houve um aumento gradativo da temperatura de 27 a 30°C ao longo do transecto, em comparação com uma área de ocupação à frente, é possível verificar as maiores temperatura com 33°C. Sugerimos um planejamento urbano que incluam casas com padrões arquitetônicos compatíveis com o clima da região, principalmente que levem consideração o conforto ambiental para os cidadãos de menor poder aquisitivo. Além da criação de parques públicos com vegetação e áreas de passeio público com arborização adequada, para amenizar o microclima local desses bairros.   Urban thermal sensation in planned residential area in the municipality of Santarém – Pará, Amazônia, Brasil   R E S U M OThe objective of this research was to evaluate the microclimatic variables, perception and urban thermal sensation of residents of a residential area planned for low income families in the city of Santarém-Pará. It was collected from data of temperature, relative air humidity and wind speed, in addition to pre-set application applications. The experiment occurred on August 15, 2018, in a transect with seven points in the residential. Forms were applied in internal area (houses) and external in the total of 115 forms, for a population aged 15 to 60 years. With the microclimatic information of the place were calculated the Temperature and Humidity, Temperature and Humidity modified and Temperature Effective as a function of the Wind, which were correlated with the subjective sensations of the local population. The results indicate that the Effective Temperature index as a function of the Wind was the most compatible with the sensation and the personal perception of the interviewees. It was very evident the thermal discomfort felt by the population, between the period of 12 to 15 h in the external area and 15 to 18 h in the internal area (houses). The brightness temperature in the residential trim cutout there is a gradual increase in temperature from 27 to 30 ° C along the transect, compared to a forward occupancy area, it is possible to check the highest temperature at 33 ° C.Keywords: Thermal Comfort, Planned area, Urban climate.

Having long desired to witness a total eclipse of the sun, I resolved to proceed to some place in the line of the moon's shadow, for the purpose of observing that which took place on the 28th of last July.Various reasons induced me to prefer the town of Göteborg in Sweden to any other station. It had interesting historical associations connected with eclipses: and there was something pleasing in the prospect of seeing the red prominences, which excited so much attention at the eclipse of 1842, at the very spot where they were observed, probably for the first time, in 1733; but a more important ground of preference, was its proximity to the central line of the moon's shadow, and its being directly accessible from England.

The scarce information we have about the life of Ristoro d’Arezzo is obtained from his only surviving work, La composizione del mondo colle sue cascioni. According to the explicit, it was finished in 1282. Ristoro (Restoro in the local phonetic form used at Arezzo) was born in Arezzo at an unknown date in the first decades of the 13th century, when the city was a stimulating intellectual center. He was an adult in 1239, when he viewed a total eclipse of the sun. There has been much speculation about his intellectual and professional background. Based on recent research, it is highly improbable that he was either a professed monk or a Dominican architect. His text is full of analogies taken from the arts of painting, mosaic, goldsmithing, and metallurgy, presenting the world as a huge mosaic waiting to be decoded. It is difficult, however, to try to identify Ristoro with contemporary local artists sharing the same name. To date, none of these ascriptions can be sufficiently proven.

The observing station selected for my party was determined upon from information supplied by the Hydrographer, Rear-Admiral Sir W. J. L. Wharton, R. N., K. C. B., F. R. S. Santa Pola appeared likely to meet the requirements of a man-of-war, and without such assistance as a man-of-war can render, the manipulation of long focus prismatic cameras in eclipse observations in a strange country is impracticable. Santa Pola lies very near the central line of the eclipse, and good anchorage was available, protected from some winds.

A summer field study was conducted in two university dormitories in the Tokai region of Central Japan. The study aimed at understanding the correlation between subjective thermal responses as well as whether nationality was affecting the responses. It was observed that nationality significantly affected thermal sensitivity and preference. The occupants’ acceptance for thermal stress was invariably above 90%. Despite the high levels of humidity observed, the multiple regression model showed that only the indoor air temperature was significant for explaining the variability of thermal sensation for both Japanese and non-Japanese students. The highest probability of voting neutral for university students in dormitory buildings in the Tokai region of Japan was estimated within 24~26.5 °C (by probit analysis). Japanese students were more sensitive to their indoor environment as opposed to the international students. The adjusted linear regression coefficient yielded from the room-wise day-wise averages were 0.48/K and 0.35/K for Japanese sensitivity and international sensitivity, respectively. In our study, the Griffiths’ model of estimating comfort temperature (or thermal neutrality) showed weak predictability and notable differences from the actually voted comfort. The neutral and comfort temperature observed and estimated in the study remained invariably below the recommended temperature threshold for Japan in summer leading to believe that that threshold is worth reevaluating.

This study has developed street lamp lighting device material that was turned on and off by self-power supply without additional power by using the rays of the sun. Lighting devices have been applied with polycarbonate materials that were outstanding with light transmissivity while using LED light and economic value. Lighting devices are easily installed in various places since external power is not necessary. In addition, it also serves as a function of preventing crime by acquiring intensity of illumination in crime-ridden district in the night. Lighting device can also serve as a function of improving fine view in the city by establishing eco-friendly circumstances including parks, areas around shopping district, and housing areas after being manufactured in the form of flowerpot where can grow plants in the future.
