InMotion, corps et architecture

Haze Kware (de son vrai nom Andriamampandry Andriantsoa) s’est d’abord consacré plus de vingt ans à la musique en tant que pianiste de jazz avant de découvrir avec la photographie le mode d’expression qui lui correspond. Il débute en couvrant des concerts et des battles hip-hop puis se lance dans un projet artistique plus personnel : « InMotion - My life in movement », ou comment magnifier l’expression corporelle en l’associant à une atmosphère et à un cadre architectural particuliers.

Photosynthetically Active Radiation Temperature Dependent Models and Its Variability with Climatic Variables over Akure, Nigeria

Photosynthetically Active Radiation (PAR) is an essential input for applications pertaining to biomass production, plant physiology, and natural lighting in greenhouses. It is the amount of light energy necessary for photosynthesis to occur, and the wavelengths of this light are typically between 400 and 700 nm. In this study, the photosynthetically active radiation for Akure (latitude 7.28°N, longitude 5.30°E, and 375 m asl.), located in the coastal region of Nigeria, was estimated and investigated using data on the monthly averaged daily global solar radiation, relative humidity, wind speed, minimum and maximum temperature from the National Aeronautics and Space Administration (NASA) archives over a thirty-eight-year period (1984–2021). In order to determine the accuracy of the models, eight (8) new temperature PAR-based models were developed for the location and statistical tests were conducted using the coefficient of determination (R2), mean bias error (MBE), root mean square error (RMSE), mean percentage error (MPE), t-test, and index of agreement (IA). The findings demonstrated that PAR for Akure is lowest in the month of August with 6.5320 MJm-2day-1 during the rainy season (April to October) and highest during the dry season (November to March), with 8.6670 MJm-2day-1 in March. The best model equation for calculating PAR for Akure was found to be the one that links the PAR and natural logarithm of temperature changes; its R2, MBE, RMSE, MPE, t-test, and IA values were 68.1%, 0.0032 MJm-2day-1, 0.5208 MJm-2day-1, -0.4479%, 0.0204, and 82.8013%, respectively.&nbsp

Poverty in the north-western part of Nigeria 1976-2010 myth or reality

Every society was and is still affected by the phenomenon of poverty depending on the nature and magnitude of the scourge. Poverty was there during the time of Jesus Christ. Indeed poverty has been an issue since time immemorial, but it has become unbearable in recent decades particularly in Nigeria. It has caused a number of misfortunes in the country including corruption, insecurity and general underdevelopment. Poverty has always been seen as negative, retrogressive, natural, artificial, man-made, self-imposed, etc. It is just some years back that the Federal Office of Statistics (FOS, NBS) has reported that Sokoto State was the poorest State in Nigeria, a statement that attracted serious heat back from the Government of the State. The Government debunked the claim, saying that the report lacked merit and that it was politically motivated. In this paper, the author has used his own research materials to show the causes of poverty in the States of the North-western part of Nigeria during the period 1976 to 2010, and as well highlight the areas in the States, which have high incidences of poverty and those with low cases, and why in each case.</jats:p
