The main goal of the minimum zone tolerance (MZT) method is to achieve the best estimation of the roundness error, but it is computationally intensive. This paper describes the application of a genetic algorithm (GA) to minimize the computation time in the evaluation of CMM roundness errors of a large cloud of sampled datapoints (0.2° equally spaced datapoints). Computational experiments have s...

The yielding arch support is transported and installed in the face with use of auxiliary machines. These activities underground mining cause many problems, which have as yet not been solved. Currently, transport assembly are carried out manually, using roadheader suspended rail, or various types mounting platforms. analysis structure existing solutions resulted development an original that met ...

the iranian plateau is characterized by diverse tectonic domains, including the continental collisions (e.g. the zagros and alborz mountains) and oceanic plate subduction (e.g. makransubduction zone). to derive a detailed image of the crust–mantle (moho) and lithosphere–asthenosphere (lab) boundaries in some tectonically units of the iranian plateau, we used a large number of s receiver functio...

The California Psychological Inventory (CPI) was administered to a sample of 71 pairs of monozygotic and 53 pairs of dizygotic twins reared apart (MZA, DZA, adult twins) and 99 pairs of monozygotic and 99 pairs of dizygotic twins reared together (MZT, DZT, adult male twins). The twin reared apart data was age and sex corrected. The twin reared together data represented one sex and a narrow age ...

Early embryonic cleavages are mostly regulated by maternal components then control of development progressively depends on newly synthesized zygotic products. The timing of the first cleavages is a way to assess embryo quality. The goal of this study was to evaluate the duration of the fourth cell cycle, at the time of maternal-to-zygotic transition (MZT) in in vitro-produced bovine embryos by ...

OBJECTIVE To characterize the incidence and risk factors for monochorionic diamniotic(MC-DA) twinning after assisted reproductive technologies (ART). DESIGN Retrospective population-based study. SETTING The study was conducted in China; Department of Reproductive Medicine Center at The First Affiliated Hospital of Anhui Medical University. POPULATION A cohort of 8860 clinical pregnancies ...

Dear Editor, The maternal to zygotic transition (MZT) is a crucial process in the early development of almost all animals, during which maternal mRNAs are degraded and the zygotic genome is activated (Li et al., 2013). How maternal mRNAs are degraded is one of the long-standing questions in the field of developmental and reproductive biology. Recently, high-throughput sequencing and genetic stu...

Transcription factors and microRNAs (miRNAs) are two important classesof trans-regulators indifferential geneexpression. Transcription factors occupy cis-regulatory motifs in DNA to activate or repress gene transcription, whereas miRNAs specifically pair with seed sites in target mRNAs to trigger mRNA decay or inhibit translation. Dynamic spatiotemporal expression patterns of transcription fact...

In this study, the total 80% of MeOH extract and also petroleum ether, CHCl3, EtOAc, n-BuOH, and the remaining MeOH fractions obtained by solvent-solvent fractionation of the whole flowering samples of Centaurea bruguierana (DC.) Hand.-Mzt. ssp. belangerana (DC.) Bornm. (Asteraceae), namely "Baad-Avard", collected from Borazjan in Bushehr Province (Bushehr, Iran) were investigated for larvicida...
