objective: the use of presently available dentin bonding systems has greatly reduced mi-croleakage; however, the ideal situation where the adhesive resin completely penetrates the demineralized dentin is not yet achieved. the purpose was to compare the microleak-age of fifth and sixth generation bonding agents at enamel and dentinal margins. materials and methods: class v cavities were prepared...

The mobility of entrepreneurs, which is an integral part of human life, can occur in all aspects of occupation and location. Finding out the general trends of mobility in entrepreneurship can be used in the effective motivational activities. As Sylhet is a remittance and raw materials rich but industrially backward area, the mobility of entrepreneurship in both aspects in this area is to be ana...

Generation Expansion Planning (GEP) is one of major modules of power system planning studies, normally performed for the nex 10-30 years horizon. The current industrial practices are to find the generation requirements based on a nodal analysis. In this way, the allocations are not determined and subequent studies are required to find the exact locations which as decomposed from the earli...

The lattice Boltzmann method (LBM) was used to analyze two-dimensional (2D) non-Fourier heat conduction with temperature-dependent thermal conductivity. To this end, the evolution of wave-like temperature distributions in a 2D plate was obtained. The temperature distributions along certain parts of the plate, which was subjected to heat generation and constant thermal conductivity condit...

this study aims to estimate economic capacity and, in turn the utilization rate of economic capacity in iran’s electricity generation industry during 1350-1388. aggregate time series data for thermal power plants are used. with parametric restrictions for linear homogeneity in input prices imposed, capital demand function is first derived and estimated. this allows the derivation of economic ca...

The objective of this study was to estimate heritability, heterosis, and genetic parameters involved in the control of forage yield and quality in kenaf populations, using analysis of generation means. Two crosses were used; Cuba 2032×Accession 75-71 and IX51×Everglade 41. Experimental material comprised of P1 and P2, their F1 and F2 and BC1P1 and BC1P2 generations. The effects of generations w...
