Erosion corresponds to the process of fragmentation, transportation, and deposition soil and/or rock fragments. It is main exogenous factor responsible for alteration earth’s surface, resulting in various geomorphological formations, many which have significant economic interest due their beauty. In this paper, we aim discuss, from an interdisciplinary perspective, general specific elements tha...

protein serine/threonine kinase (ROCK), is one of the central regulatory molecules for cytoskeleton control and cell adhesion process. ROCK also involves in other cell functions such as apoptosis and tumor invasiveness. Rho kinase is thought to play an important role in a variety of cellar functions such as stress fiber formation, focal adhesion formation, cell aggregation, cell morphology, cyt...

In this work, the effect of rock bolt angle on the shear behavior of Rock Bridges is investigated using the particle flow code in two dimensions (PFC2D) for three different Rock Bridge lengths. Firstly, the calibration of PF2D is performed to reproduce the gypsum sample. Then the numerical models with the dimensions of 100 mm * 100 mm are prepared. The Rock Bridge is created in the middle of th...

No prior research has documented the different types of rock coatings in Yosemite Valley, despite the evident black streaks down Yosemite Falls, the light granitic rock exposed by recent rock falls contrasting with dark rock coatings, and the millions of visitors who have photographed the coated rocks of Yosemite. This paper identifies the types of rock coatings found on Half Dome, in Yosemite ...

Background: Infertility is estimated to affect up to 15% of couples of reproductive age, and male factors contribute to 50% of these cases. Globozoospermia syndrome is a severe form of teratozoospermia, with an incidence of less than 0.1%. It is characterized by round sperm head. The most prominent feature of globozoospermia is the malformation of the acrosome, which is totally absent in the to...

Introduction: We have completed analysis of a new near-field rock count at the Mars Pathfinder landing site and determined that the previously published [1,2] rock count suggesting 16 % cumulative fractional area (CFA) covered by rocks is incorrect. The earlier value is not so much wrong (our new CFA is 20%), as right for the wrong reason: both the old and the new CFA’s are consistent with remo...

Abstract Because of their extreme heterogeneity at multiple scales, carbonate rocks present a great challenge for studying and managing oil reservoirs. Depositional processes diagenetic alterations carbonates may have produced very complex pore structures and, consequently, variable fluid storage flow properties hydrocarbon To understand the impact mineralogy on system, we analyzed four rock sa...

the culture media optimization is an inevitable part of upstream process development in therapeutic monoclonal antibodies (mabs) production. the quality by design (qbd) approach defines the assured quality of the final product through the development stage. an important step in qbd is determination of the main quality attributes. during the media optimization, some of the main quality attribute...

prolonged local consumption of anethum graveolens leaves, as an antihyperlipimic and antihypercholesterolemic agent, has been associated in some patients with skin disorders such as darkening and pigmentation mainly in the exposed areas such as face and hands.anethum graveolens belongs to the umbelliferae family which is belived to be rich in photoactive furocoumarins. an oraganic extract of th...

background: the initial step in the diagnostic investigation of male infertility has been traditionally based on the conventional seminal profile. however, there are significant limitations regarding its ability to determine the underlying mechanisms that cause the disorder. sperm dna fragmentation has emerged as a potential causative factor of reproductive failure and its assessment has been s...
