The Study of the Formation of Negatively Charged Electrolysis Hydrogen Bubbles and Their Size Control Under Microgravity Conditions for Separation of Solid Inclusions from Fluid
Abstract: The previously conducted theoretical description of the mechanism of formation of negatively charged electrolysis hydrogen bubbles and control of their size under terrestrial conditions, confirmed experimentally, permitted to conclude that negatively charged electrolysis hydrogen bubbles, floating up in a fluid, meet on their way the solid particle with dimensions much larger than the size of bubbles and induce a positive charge on the surface of the solid particle. As a …

Flow Simulation and Experimental Comparative Study of Aerodynamic Forces on NACA 2415 Airfoil Scaled Model
Abstract: Aerodynamic force, which would be brought upon by the relative motion of an object and the airflow, is the force that the air in which the body is submerged exerts on the body. The normal force resulting from force on the body's surface and the shear force resulting from airflow viscosity, also known as skin friction, are the two sources of aerodynamic force. Shear force is applied locally and parallel …

A smart fluids; Magneto rheological, ferrofluid, and nanofluids; a prospect for Medical and Technological application
Abstract: The physiochemical and biomedical applications of smart fluids, typically ferrofluid, magnetorheologicalfluids, and nanofluids are studied. It is predicted that these fluids are impacted by the three most important rheology parameters, namely strain, magnetic field, and temperature. The magnetoresistive contribution is treated in terms of drug force in order to determine thecoefficient of viscosity. The research presents that the viscosity of studied fluids will increase in proportion to applied magnetic field. …

Insilico Modelling and Comparative Docking Studies of EWS-FLI1 Responsible for Ewing Sarcoma in Human Beings
Abstract: Ewing’s sarcoma (EWS) is a small round-cell tumor typically arising in the bones, rarely in soft tissues, of children and adolescents. Patho-genomic translocations involving the EWS gene on chromosome 22 and an ETS-type gene (Fli1) on chromosome 11, are implicated in more than 95% of Ewing’s sarcomas. A chimeric transcript that consists of the N-terminus of EWS i.e., Transcriptional Activation Domain is fused to the C-terminal portion of FLI1 i.e., …

Isolation and Characterization of Lantibiotic Producing Lactic Acid Bacteria from Ambali, Aged Mango Pickle Probiotics
Abstract: Each year in the US at least 2 million people are sickened with antibiotic resistant infection. The development of antibiotics was one of the most important advances of medicine. Many bacterial infections (e.g. tuberculosis and infected wounds) that previously had no effective treatment and often killed people became treatable with antibiotics, saving millions of lives. Now, because of the overuse and misuse of antibiotics, bacterial infections that were once easily …

A Review on Junk DNA
Abstract: For many years, although being incredibly catchy, the term junk DNA discouraged mainstream scientists from exploring noncoding genetic material. Among humans, the DNA that actually codes for protein synthesis is 2% only. Hence, the noncoding region of genome is then termed Junk DNA. The junk DNA component is drastically different. Hence at the time of investigating the role of satellite DNA for the fertility and survival in pure species, the …
