Particle Size Analysis of Soil Obtainable in Maiduguri, Nigeria

Adequacy of laser diffraction for soil particle size analysis

Sedimentation has been a standard methodology for particle size analysis since the early 1900s. In recent years laser diffraction is beginning to replace sedimentation as the prefered technique in some industries, such as marine sediment analysis. However, for the particle size analysis of soils, which have a diverse range of both particle size and shape, laser diffraction still requires evalua...

Effect of Geogrid Aperture Size and Soil Particle Size on Geogrid-Soil Interaction under Pull-Out Loading

Craniofacial Classification of Normal Newborns in Maiduguri Metropolis, Nigeria Clasificación Craneafacial de los Recién Nacidos Normales en Maiduguri, Nigeria

Anthropometric measurements, such as craniofacial forms especially in the first days after birth are important for the assessment of neonatal health status and results obtained from such measurements are used in pediatrics, orofacial surgery and diagnostic comprehension between patient and normal populations. There is no published literature about the types of head and face shapes in the Kanuri...

Physicochemical Parameters in Soil and Vegetable Samples from Gongulon Agricultural Site, Maiduguri, Borno State, Nigeria

Anthropogenic activities are a leading cause of metal emission, often associated with high elevated soil and plant metal concentrations. The accumulation of heavy metals and anions in soil and vegetables in the vicinity of Gungulung agricultural site were investigated. Soil samples were collected at depths of 0-5 cm, 5-10 and 10-20 cm. Soil properties including pH, electrical conductivity (EC),...

Alternative soil particle-size analysis by gamma-ray attenuation

In 1992 a new method of soil particle-size analysis was introduced, which coupled sedimentation to gamma-ray attenuation. The theoretical possibility of an alternative for this method is here presented, which includes the necessity of sieving soil samples, but simpli®es the gamma-ray measurements. Advantages and disadvantages of this alternative are discussed. # 1999 Elsevier Science B.V. All r...
