There have been numerous researches focusing on the alternatives to conventional concrete regarding environmental benefits and trade-offs. For this purpose, nowadays, Life Cycle Assessment (LCA) is widely used. Until now, LCA results of green concretes shown some limitations, paper focuses addressing them. Firstly, mostly based a small number concretes, which can limit possibility quantify rang...
Diminished ovarian reserve is a more common occurrence as more women postpone childbearing in modern societies due to social and demographic trends. Diminished ovarian reserve is one of the primary reasons for poor ART outcome. Due to high costs, side effects and heavy burden on patients on ART treatments, patient selection and counseling for prognosis is an important aspect before starting ART...
In the West, the history of writing on art goes back to the classical antiquity but writing art history began with Giorgio Vasari’s 16th-century pioneering work on the artists’ biographies.

The first important comparison is between the birth time of ar...
A profound cytotoxic action of the antimalarial, artesunate (ART), was identified against 55 cancer cell lines of the U.S. National Cancer Institute (NCI). The 50% inhibition concentrations (IC50 values) for ART correlated significantly to the cell doubling times (P = 0.00132) and the portion of cells in the G0/G1 (P = 0.02244) or S cell cycle phases (P = 0.03567). We selected mRNA expression d...
Two-literal clauses of the form L R occur quite frequently in logic programs, deductive databases, and { disguised as an equation { in term rewriting systems. These clauses deene a cycle if the atoms L and R are weakly uniiable, ie. if L uniies with a new variant of R. The obvious problem with cycles is to control the number of iterations through the cycle. In this paper we consider the cycle u...

SUMMARY ANSWER The Belgian national register shows that the introduction of reimbursement of ART laboratory costs in July 2003, and the imposition of a legal limitation of the number of embryos transferred in...
in the present work, multidimensional modeling of open-cycle process of om355 engine was developed. calculations for computational mesh were carried out. the results of the model were validated by experimentally measured in-cylinder pressure and the good agreement between calculations and measurements approved the trustworthy of numerical code. results included pressure, temperature, emission a...
