This article analyses the dynamics land use in Lake Chad area located Extreme East of Nigerien territory region Diffa. The study was conducted by using approach “Land-Use and Land-Cover Change (LULCC.” digital satellite pictures Landsat TM for year 1990, ETM 2010 2018 were used. analysis soil occupation indicated some significant changes milieu. food market gardening crops produced during perio...

Field investigations at Dugway Proving Ground in western Utah have produced new data on the chronology and human occupation of late Pleistocene and early Holocene lakes, rivers, and wetlands in the Lake Bonneville basin. We have classified paleo-river channels of these ages as “gravel channels” and “sand channels.” Gravel channels are straight to curved, digitate, and have abrupt bulbous ends. ...

Damage to the supporting structures, disruption of the cementing substance binding the nail plate to the surrounding structures or formation of granular layer, which is otherwise absent in a normal nail bed and nail matrix, will produce onycholysis. Trauma from physical factors, manicuring, foreign body implantation or chemicals like solvents, various nail cosmetics and immersion in alkaline so...

creasing for the two following days. On the fourth day of his illness, the giddiness increased very much and he began to vomit and had fever, which passed off in two or three days. The objects around him, he felt, were moving, and it was for the treatment of his vertigo that he came to hospital to be treated. The patient named Dukhi, a Hindu male, aged 22 years, is a muscular man of active liab...

Australia has experienced a sudden and unexpected resurgence in bed bug infestations from both Cimex lectularius L. and Cimex hemipterus F. A survey in 2006 revealed that infestations had increased across the nation by an average of 4,500% since the start of the decade. In response, a multi-disciplinary approach to combat the rise of this public health pest was implemented and involved the coor...

A two fluid model (TFM) was used to study gas-solid heat transfer in a riser with different inclination angles. A two dimensional pipe with 5.8 cm internal diameter and 5 meter length was chosen.  Effect of bed angle and solid particles feed rate were studied on the heat transfer behavior of gas and solid particles. Obtained results from simulation are compared with the experimental data in the...

Fluidization of non-spherical particles is widely practised in chemical engineering processes. In this work, the mixing and dispersion behaviours a bubbling fluidized bed (BFB) are explored by computational fluid dynamics-discrete element method (CFD-DEM) featuring super-quadric model to describe particle morphology. After validation, general flow patterns, solid mixing, ellipsoid studied, toge...

computational fluid dynamics (cfd) is a computational technology that enables researchers to study the dynamics of things that flow. by using cfd, it is possible to build a computational model that represents a system under study. it not only predicts fluid flow behavior, but also the transfer of heat, mass, phase change, chemical reaction, mechanical movement, and stress or deformation of rela...
