Design and Construction of Pressure Membrane Apparatus for Measurement of Soil Moisture Tension of Soils under Laboratory Condition
Environmenatal factors such as climate change, gradual decrease in water resources and threatened habitants prompted the need to monitor our environment and implement better policies to protect it, thus monitoring soil pF (potential factor) values become increasingly important for environmental monitoring. The commonly available instrument(tensiometer) do not measure the range of available moisture in all soil types rather measures soil water suction. The need to measure the range of available moisture in all soil types with accuracy led to the modification of tensiometer for satisfactory laboratory results. Due to the shortcomings associated with tensiometer readings, the pressure membrane apparatus is an important instrument for optimizing irrigation and erosion prediction models.This pressure membrane with extractor has two main components:a porous plate with air entry pressure and a sealed pressure cell. The soil from which pF value was to be determined was placed in a chamber in which the pressure increased above atmospheric pressure. The side of the chamber which supports the soil consists of a pressure relief valve supported on a pressure hose. This is to ensure that the extractor chamber was not over-pressurized. The soil water potential with the corresponding mositure contents of four soil samples: A (clay soil), B(loamy soil), C (sandy soil) and D (silt) obtained from different locations were determined using pressure membrane apparatus. At a potential of 104hPa, samples A,B,C,D showed moisture content of 0.05,0.25,0.30, and 0.45cm3/cm3respectively. From the obtained results, at potentail close to zero, sandy soil is close to saturation and moisture held in the soil, primarily by capillary forces. From the laboratory analysis, moisture content decreases with high moisture cohesion.

Effects of Phenolic Compounds on Environment
In recent years the natural supply of phenolic substances has been greatly increased due to the release of industrial byproducts into the environment. Phenol is one of the most widely used in the organic compounds in existence and is a basic structural unit for a variety of synthetic organic compounds including agricultural chemicals and pesticides. Among all the toxic compounds, phenol and its substituent phenolic compounds contribute a remarkable adverse impact to the environment. These are major xenobiotics, which are often found in the effluents discharged from the industries such as paper and pulp, textiles, gas and coke, fertilizers, The US Environmental Protection Agency (EPA, 1979) had classified the phenolic compounds as high priority pollutants due to their extensive impact on the deterioration of the water environment. In this review paper, we described about plant phenolic compounds, phenolic effects of human exposures, animal exposures, effect on children, reducing the risk of exposure and medical tests to determine concentration of phenol. Key Words: Phenol, Environment, plant phenolic compounds, Human Exposures, Animal Exposures and medical tests.

Epididymal Bilharziasis
The urinary bilharziasis are parasitic affections whose pathogenic agent is Schistosoma. Only the urogenital schistosomiasis due to the species S. haematobium exists in Morocco. The testicular sites of bilharziomas are rare. We report an interesting case of epididymal bilharziasis in a young man with only apparently benign nodules of the testes on imaging.

Evaluation of a formulated synthetic-based mud properties on its cuttings carrying capacity using factorial design
In drilling mud formulation, evaluating the mud cuttings carrying capacity provides the means of establishing its wellbore hole cleaning potential. Thus, a synthetic-based mud was formulated from derived ester and evaluated for its mud weight and rheological properties: plastic viscosity and yield point. A two level-three factors (23) full factorial design was performed to evaluate the cuttings carrying index (CCI) of the formulated synthetic-based mud. This offers the privilege of assessing the combined effect of these factors: plastic viscosity, yield point and mud weight on the cuttings carrying capacity of the mud. The factors’ levels (low and high) from the formulated mud properties measurement were 6 and 17cp, 10 and 13lb/100ft2, and 8.63 and 9.50lb/gal for plastic viscosity, yield point and mud weight respectively. Thus, the experimental design results obtained, resulted ingood cuttings carrying capacity (adequate hole cleaning) as the obtained CCI values were above 0.5. Additionally, the results further revealed main effect from the formulated mud’s rheological properties and mud weight on its cuttings carrying capacity. Furthermore, the experimental design result depicted that there was interaction effect between the rheological properties, whilst there was no interaction effect between the rheological properties and the mud weight at the considered factors’ level. Therefore, a potential synthetic-based mud with adequate wellbore hole cleaning capacity could be formulated at the considered mud properties.
