the aim of this work was to optimize the coagulation-flocculation (cf) process applied tomunicipal wastewaters (ww). optimization of cf was performed to minimize chemical oxygen demand(cod), turbidity, sludge produced, and some metals in sludge. a box-behnken design was used to evaluate the effects and interactions of three factors such as type of biopolymer (guar, mesquite seed gum and opuntia...

Composite edible coatings were formulated with candelilla wax alone, and candelilla wax blended with beeswax, white mineral oil and oleic acid (2:1 ratios) as the lipid phase, and mesquite gum as the structural material and their corrected water vapor permeability (WVPc) were determined. The coatings were applied to Persian limes and their effect upon physiological weight loss, color and chemic...

The synthesis that is described in this study is for the preparation of silver nanoparticles of sizes ranging from 10 nm to 30 nm with a defined shape (globular), confirmed by UV-vis, SEM, STEM and DLS analysis. This simple and favorable one-step modified Tollens reaction does not require any special equipment or other stabilizing or reducing agent except for a solution of purified mesquite gum...

Density of honey mesquite (Prosopis glandulosa) has increased in the southwest USA during the last century. Mesquite in dense thickets reduce grass production and plant species diversity. Prescribed frre is currently the least environmentally challenged and most economically sustainable option to manage mesquite. However, few mesquite over 1 year old are completely killed by frre. Moreover, the...

BACKGROUND: A computerized statistical analysis of allergy skin test results correlating patient reactivities initiated our interest in the cross-reactive allergens of mesquite tree pollen. In-vitro testing with mesquite-sensitized rabbits and a variety of deciduous tree pollens revealed so many cross-reactivities that it became apparent there could be more allergens in mesquite than previously...
