Groundwater flow in an idealized atoll platform is simulated with CASTEM 2000, a computer code developed at the CEA (Commissariat à l’Energie Atomique). Darcy’s law and a coupled solute transport equation (diffusion–dispersion–convection) is solved by the mixed-hybrid finite-element method. Inward and upward circulations of oceanic water are shown to occur. These steady-state circulations resul...

Ohio has substantial lands impacted by surface mining for coal and an active steel industry. Steel industry slags have been used as liming compounds for agriculture and acid mine soil reclamation. This 3-year study evaluates slags from Ohio steel mills in greenhouse trials where these materials are compared to reagent grade CaCO 3 in their ability to improve plant growth on acid mine soil. The ...

In acid soils, Al toxicity and nutrient deficiencies are main constraints for low yield of cacao (Theobroma cacao L.). A controlled growth chamber experiment was conducted to evaluate the effect of three Al saturations (0.2, 19, and 26%) adjusted by addition of dolomitic lime on growth and nutrient uptake parameters of cacao. Overall, increasing soil Al saturation decreased shoot and root dry w...

Particle emissions into the atmosphere can cause extensive damage to environment and human health. To improve efficiency in collection of submicronic particles, new filtration media appeared on market due textile technologies equipment, such as filter developed with polytetrafluoroethylene (PTFE) membranes; however, these are more expensive. A coating technique called precoating is a economical...

the construction industry is a major consumer of new materials. given that material production for construction work accounts for a significant percentage of all energy consumed nationally in newly developing countries, it becomes vital that the construction industry strives to reduce waste at all stages of construction. however, the importance of these construction wastes in terms of types and...

conclusions independent of the training sequence, an 8-week concurrent training program caused positive changes in the body composition and physical fitness of our aged female subjects. however, there was no benefit derived from sequence order training. results the intra-session sequence order did not influence the adaptive response of the waist-to-hip ratio (p = 0.55), body fat percentage (bf ...

background: the pistachio is a nut produced by about 20 species of shrub. present-day studies show the health benefits of pistachio in preventing or treating diseases such as diabetes, cardiovascular diseases (cvds), cancer, multiple sclerosis (ms), and erectile dysfunction. materials and methods: medline / pubmed, and google scholar databases were searched using the keywords of pistacia vera, ...
