Objective: To determine the initial mechanical stabilization of conventional glass ionomer cements (GICs) indicated for atraumatic restorative treatment (ART) in different storage periods. Material and Methods: Specimens were divided according to GIC (n=12): IZ - Ion-Z, KM Ketac Molar Easymix, RS Riva Self Cure, GL Gold Label 9. They prepared stored distilled water. Superficial microhardness (S...

the burgers’ equation is a simplified form of the navier-stokes equations that very well represents their non-linear features. in this paper, numerical methods of the adomian decomposition and the modified crank – nicholson, used for solving the one-dimensional burgers’ equation, have been compared. these numerical methods have also been compared with the analytical method. in contrast to...

This study investigates novel deposition techniques for the preparation of TiO2 electrodes for use in flexible dye-sensitized solar cells. These proposed new methods, namely pre-dye-coating and codeposition ultrasonic spraying, eliminate the conventional need for time-consuming processes such as dye soaking and high-temperature sintering. Power conversion efficiencies of over 4.0% were achieved...

As a vector control program to control Chagas disease in Guatemala, residual spraying of Rhodnius prolixus and Triatoma dimidiata was performed, and its impact was measured in the department of Zacapa. In order to identify infested villages and determine the degree of infestation, a baseline entomological survey to identify municipalities infested with vectors followed by an additional vector s...

In this study, newly developed NiCrB and conventional NiCrTi coatings were produced by arc spraying using compressed air nitrogen as atomization gases. way, four with different oxide contents produced. The investigated in terms of their phase compositions, oxygen contents, microstructures. results showed that the pronouncedly reduced nitrogen-atomized compared to air-atomized. about one-fourth ...

an investigation was made to study the residual activity and air- borne effect of pirimiphos- methyl, at 2g a.i./m2 in hut scale trials on different surfaces in kazeroun, and bandar-abbas, south of iran. in kazeroun area, bio-assay contact mortality test with pirimiphos methyl on mud, wood, cement and plaster surfaces, 54 days after hut spraying, decreased from 100% to 46.7%, 61.25%, 36.6% and ...

Tests of pulmonary function (FVC, FEV1, FEV 1%, and single breath CO diffusion), renal function (serum creatinine and BUN), liver function (serum ALT, AST, and ALKP) and a full haematological screen were performed on 27 paraquat spraymen (mean spraying time 5.3 years; mean individual annual quantity of paraquat handled, 67.2 kg as paraquat ion) and on two control groups. One of the control grou...
