in order to prevent the shrinkage of olive fruit and maintain its fresh being, and  also to increase the oil content and dry matter, the effect of kaolin at three levels of application (0, 2.5% and 5%) on four varieties of olive (mission, conservolea, keillet, blady) was evaluated within a period of four months, in ahwaz, the tests being repated in 3 replicates. results revealed significant eff...

Objective: The incidence and prevalence of kidney stone is increasing worldwide. After the first recurrence the risk of subsequent relapses is higher and the time period between relapses is shortened. Urinary stones can be severely painful and make a huge economic burden. The stone disease may increase the vulnerability of patients to other diseases such as renal failure. Medicinal herbs are ri...

Background & Aims of the Study: The wastewater created as a result of stone cutting industries enters some pools for re-consumption so that its suspended solids settle by gravity. By taking to account the high volume of water and sludge, treatment of wastewater and removal of sludge cause many problems for stone cutting units. The objective of this study was to determine the quality of wast...

background and aims. although microwave irradiation has been used for disinfection of dental stone casts, there are concerns regarding mechanical damage to casts during the process. the aim of this study was to evaluate the effect of microwave irradiation on the compressive strength (cs) and diametral tensile strength (dts) of stone casts. materials and methods. in this in vitro study, 80 cylin...

This study experimentally investigates the effect of multi-walled carbon nanotubes (MWNT’s), as a reinforcing material, on the physical properties of heavy-weight oil well cements. A candidate well is selected and the properties of the cement slurry used in a problematic section of the well are tested in the laboratory. Carbon nanotubes (CNT’s) are added as fibers to the cement slurry and the i...
