Interacting Dark Fluids in LRS Bianchi Type-II Universe

Vijay Gulabrao Mete, Pratiksha Brahmadeo Murade, Abhijit Shankarrao Bansod
At the present paper, Locally Rotationally Symmetric (LRS) Bianchi type-II cosmological model with interacting dark matter (DM) and holographic dark energy (DE) have been discussed. In order to obtain solutions of the field equations, it is assume that the shear scalar (σ) is proportional to expansion scalar (θ). To have a general description of holographic dark energy and dark matter, a phenomenological parameterization of dark energy in terms of its equation of state (EoS) has been taken. Stat...

Inhibiting Effect of Dioctyl Phthalate on the Corrosion of Mild Steel in 1.0 M Hydrochloric Acid Solution

Michael Emmanuel, Bethrand T. Nwufo, Mbanefo M. Ekwenchi
Steel corrosion is a major and costly problem to industrialists and construction workers. The inhibiting effect of dioctyl phthalate on the corrosion of mild steel was carried out in 1.0 M solution of HCl as the corrosion medium using the weight loss method. The adsorption of the dioctyl phthalate on the surface of the mild steel in 1.0 M HCl was found to follow the physisorption mechanism and also follow the first order rate law.

Analysis of Spatial Sensitivity Based on Electrostatic Monitoring Technique in Oil-Lubricated System

Zelai Jin, Fuqiang Zhang
In this paper, for the detection of wear particles in lubricating oil roads, by an-alyzing the particle belt motor, a mathematical model of the oil circuit electro-static sensor considering the dielectric constant is proposed. At the same time, the concept of spatial sensitivity and visual field is introduced. The influencing factors of the position of the charged abrasive particles, the axial

Evaluation of Concentrations of Heavy Metals in Water Used in Agricultural Irrigation

Marcio Antonio Ferreira Camargo, Thaiany Aparecida Ribeiro Pereira
The knowledge about toxic levels of toxic heavy metals in irrigation water is very scarce and quite varied. This work aimed to evaluate the concentrations of toxic heavy metals in the lake of the Experimental Farm UEMG, Passos-MG Unit. The toxic heavy metals evaluated were Cadmium (Cd), Chromium (Cr) and Lead (Pb). The lagoon was divided into ten strategic points for sampling, each point being sampled in triplicate. The pH of the

Correlation of Brownian Motions and Its Impact on a Reinsurer’s Optimal Investment Strategy and Reinsured Proportion under Exponential Utility Maximization and Constant Elasticity of Variance Model

Silas A. Ihedioha
This work investigated a reinsurer’s optimal investment strategy and the pro-portion he accepted for reinsurance under proportional reinsurance and expo-nential utility preference in the cases where the Brownian motions were corre-lated and where they did not correlate. The reinsurer invested in a market in which the price process of the risky asset is governed by constant elasticity of variance (CEV) model. The required Hamilton-

Agenesis of Internal Carotid Artery and Ischemic Stroke, One Case Report: A Review of Literature

Mapaga Nyangui Jennifer, M. Martinez, P. Desbordes, A. Diawara, R. Houeze, C. Laurent, J. Jacquin
Background: Agenesis of the internal carotid artery (ICA) is a rare anatomic variation of the cerebral circulation. A malfunction during the embryonic peri-od is at stake. It is very often asymptomatic and therefore discovered inci-dentally. Association with ischemic stroke is exceptional. Physiopathology is uncertain; the hypothesis of a blood flow reversal is reported in the literature. The diagnosis is based on the abs

An Extraordinary Case of Idiopathic Chylothorax in a Rural Setting

Kevin Chow Kuan Yee, Ong Tze Hern, Ng Zxai Ching, Naganathan Pillai, Adelyn Henry, Lee Tiong Chan
Chylothorax is a rare cause of pleural effusion, which can be divided into traumatic and non-traumatic causes. Often, the cause of a non-traumatic chylothorax is challenging. We report a young gentleman with idiopathic chylothorax who was diagnosed in a rural hospital with limited resources. This was confirmed on clinical presentation, pleural fluid analysis, CECT imaging and a diagnostic lymp

Five Years after Discovery Abnormal Neutrino Radioactive-Isotope (ANRI) Absorption

O. B. Khavroshkin, V. V. Tsyplakov
Several years ago, the authors were finally convinced of the reality of the ex-istence of the anomalous neutrino radioisotope (ANRI) absorption. Taking into account the applied and fundamental importance of the effect, as well as the need for thorough repetition and verification of the results of primary research, the authors repeated methodologically and technically the first effective work, but the ANRI-effect registration proce
