Analytical Approach to Determine Fundamental Performance Simplified Rocket Trajectory Motion
Abstract: The natural rocket motion is just a trajectory motion if there is no special equipment assembled to deviate, and direct it follow anther root. As result, achieves maximum height or range based on design requirement. The two trajectory roots in rocket motion are A) powered trajectory motion until burn out, and B) pure trajectory motion after burn out until landing or Parachute ejection. The former condition involves two trust force …

Determination of the Activation Energy of a TL Peak Without Prior Knowledge of Order of Kinetics
Abstract: In the present study, we extend the peak shape method of Chen for fractional intensities x =2 3 and 4 5.The novelity of the method is that it does not require the prior knowledge of order of kinetics which does not admit a straight forward evaluation. The present method has been successfully applied to computer generated TL peaks resulting from kinetic order model (KOM). The validity of the present sets …

The Effects of HIV/AIDS Worldwide
Abstract: The Human Immunodeficiency Virus (HIV), which targets immune system conductors (CD4 cells), has infected millions throughout the world. HIV lowers the body's defences by infecting certain bodily fluids (blood, sperm, vaginal fluids, and breast milk) through unprotected sex, contaminated needles, or mother-to-child transmission. Early flu-like symptoms may go unrecognised, but if not treated, HIV advances to AIDS, which is characterised by severe immune system impairment. However, advances in antiretroviral therapy …

Optimized Design and Control of Oil Exploitation Strategies: An Assisted Approach
Abstract: Because there are so many factors and scenarios to consider, optimizing oil exploitation tactics requires complicated decision-making. Conventional approaches frequently concentrate on particular elements of the design infrastructure, which restricts their capacity to fully handle the process. In order to maximize a set of oil exploitation variables in a hierarchical fashion, this research proposes a novel assisted optimization technique that combines mathematical algorithms with engineering analysis. By grouping variables into …

The Milklipidometric Model: A Mathematical Equation-based on Electric Conductivity to Predict Butterfat Concentrations in Bovine Milk
Abstract: The milklipidometric model is a mathematical equation to predict butterfat in raw milk and it is based on electric conductivity principle. The model differs from the existing equations in that it uses variables (electric conductivity, and volume fraction of whole milk ) which can be easily measured and it predicts fat at wide temperature, range of 5–60°C. Accurate results can be obtained even using commercial electrical conductivity meters, hence making …

Principles of Interpolating Prognostication in Oncology
Abstract: AbstractThe precise prediction in oncology plays a critical role in prevention, treatment, assessment of the effectiveness of methods of treatment and treatment outcomes for cancer patients. Some medical researches claim that statistical processing (factor analysis) permits to precisely individualize the prognosis, which determines the possibility of an individual approach to monitoring and postoperative treatment of patients. However, factor analysis permits only creating a matrix of factors that can significantly describe …

Classical Physics versus Quantum Physics: An Overview
Abstract: Newtonian mechanics is the foundation of Classical Physics. Newton’s mechanics, Thermodynamics, Wave theory of Optics and Maxwell’s electromagnetic theory belong to regime of Classical Physics and can be used to explain a wide range of phenomena in the Universe at macroscopic scale. These theories fail spectacularly when applied to phenomena in the atomic and nuclear regime, for example, proton-atom scattering or the flow of electrons in a semiconductor. Quantum mechanics …
