A primeira estratégia que aponto está claramente presente no livro Crónicas com Fundo de Guerra (2011). juventude em Benguela, e (ii) através de uma desnacionalização progressiva do espaço narrativo. Para desenhar este percurso parto da leitura das suas obras mais recentes que analiso da seguinte forma: (i) através da expressão de uma nostalgia pela inocência perdida de sua. Neste artigo procuro dar uma visão global da obra do escritor angolano Pepetela, analisando o seu percurso desde o visionário utópico filiado ao movimento de libertação até à sua contemporânea voz crítica, desiludida. Work in party-months was essentially as follows: surface geology, 519 seismograph, 227 gravity, 112 magnetometer, 31 structure drill, 56 electrical prospecting, 5½. Marked increases were shown over last year in almost all lines of geological and geophysical exploration. Active petroleum exploration was carried on in the following countries: Algeria, Angola, Belgian Congo, Cameroun, Egypt, Ethiopia, French Equatorial Africa, French West Africa, Libya, Madagascar, French Morocco, Mozambique, Nigeria, Somalia, British Somaliland, Sudan, Tanganyika, Tunisia, Union of South Africa, and Zanzibar. Exploratory drilling was 4% successful and development drilling was 68% successful. Ninety-four exploratory and 70 development wells were drilled in Africa during the year. A total of 634,000 feet of exploratory and development drilling was carried out during the year, exceeding all previous years, and 34 rigs were in operation at year's end. Principal wildcat discoveries of the year are oil and gas in the Akata well in Nigeria, gas in the Bomono area in Cameroun (French Mandate), shows of light oil in the Cacoba well in Angola, and the discovery of the Bled Khatara field in French Morocco. to be the only producing countries although Tunisia has closed-in gas production awaiting pipeline facilities, and development drilling for gas production was under way in French Cameroun. Egypt, French Morocco, and Algeria continued. Particularly noteworthy was the increase in Algeria to a total of 643,000 barrels, nearly double last year's production. Production for the year was 18,031,047 barrels, an increase of a half million barrels over the previous record attained last year. Read moreĪfrica reached new highs both in petroleum production and in petroleum exploration activity in 1953. The estimation bias of TRMM is also more consistent which means that the results presented in the present study can be used in an operational environment to reduce the precipitation estimation error. The results also show that the estimates from the TRMM are more accurate than the estimates offered by the other products, a conclusion which is in line with previous studies and which may be explained by the fact that this is the first product to incorporate measurements from precipitation radar. It is believed to be one of the most complete data sets of monthly precipitation data from Angola.The four remote-sensing products are able to describe the main features of the spatial and temporal variability of annual and monthly precipitation in Angola. The data set of precipitation ground observation measurements was collected by the authors from different sources in Angola and Portugal, and is the result of an intense effort to gather hydrological records from Angola. The present study examines the performance of four of these products in Angola, namely the Tropical Rainfall Measuring Mission (TRMM) 3B43 (version 6), Global Precipitation Climatology Project (GPCP) Combined Precipitation Data Set (version 2.2), Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks (PERSIANN) and the National Oceanic and Atmospheric Administration (NOAA) Climate Prediction Centre (CPC) Morphing Technique (CMORPH), by comparing annual and monthly precipitation estimates with ground observation measurements. standard products offering precipitation estimates on a regular basis is now available and may be used for water planning and management purposes.
The use of remote sensors installed in satellites can be very useful in overcoming this challenge, enabling the improvement of the spatial variability description of this variable and the extension of data series.A number of. In situ ground observation measurement of precipitation is difficult in sparsely populated areas with trying access conditions, as is the case in many countries in Africa.
