This paper describes some results of the research in the area of some additives like, methanol, ethanol etc. mixture in gasoline. The world research are become scare and measure crunch is found in case of crude oil and petroleum product.
In this chapter, we will consider the crystal structure of most metallic elements, nonmetals from column IV of the periodic table, and noble gases. Arsenic and selenium from columns V and VI, respectively, are also included in our analysis. More than 30 elements crystallize in two monoatomic crystal structures, fcc an…
Objective: Quantitatively evaluate the metabolic abnormalities in cortical gray matter (cGM) of Multiple Sclerosis (MS) patients using chemical exchange saturation transfer (CEST) magnetic resonance imaging (MRI) and assess the relation of CEST-derived indices sensitive to glutamate (GluCEST) with cognitive measures.…
ABSTRACTThe effectiveness of Oligochitosan in Suppressing the Growth of Fungal PathogenRigidoporus lignosus [(Klotzsch) Imazeki] the Causal Agent of White Root Rot Disease of Clovesin VitroWhite root rot disease caused by fungi Rigidoporus lignosus (Klotzch) Imazeki is an important disease of cloves that can cause the…
Objective of study is to determine thermal properties of an insulating material from thermal impedance spectroscopy. Plaster used as binder is less than thermal insulating kapok, however thermal characteristics of kapok-plaster material, formed in Semi-conductor laboratory and Solar Energie (UCAD/Senegal), are closer…
In this paper, studies are presented that characterize a bulk amorphous Fe61Co10Ti3Y6B20 alloy. Samples were fabricated in two forms: as a rod of 1 mm in diameter and as a tube of 1 mm in the outer diameter. The investigated material was obtained using the injection method, whereby the liquid alloy was injected into a…

In this research, the chemical synthesis and densification behavior of Ag/ZnO metal-matrix composites were investigated. The initial precipitates were obtained by adding ammonium carbonate solution to silver and zinc nitrate solutions. The precipitates consisted of silver and zinc carbonates. The thermal behavior of t…
An annular-shaped booster pellet has been developed in order to study the capability of such a design to initiate the detonation of insensitive high explosives (IHE). The detonation characteristics of an annular booster design were studied theoretically by numerical simulation and experimentally. Results showed that i…
The title compound, tetra-sodium hepta-nickel hexa-arsenate, was obtained by ceramic synthesis and crystallizes in the monoclinic space group C2/m. The asymmetric unit contains seven Ni atoms of which two have site symmetry 2/m and three site symmetry 2, four As atoms of which two have site symmetry m and two site sym…
Створено модельну композитну систему на основі суміші гідрофобного (АМ1–300) і гідрофільного (А-300) кремнеземів, дріжджових клітин, води і n-декану. Досліджено вплив нанокремнеземів на інтенсивність росту дріжджів роду Saccharomyces cerevisiae. Показано, що наявність композита забезпечує життєдіяльність дріжджових кл…
Traditional magnetic resonance imaging (MRI) contrast agents mainly include superparamagnetic (SPM) iron oxide nanoparticle as T 2 contrast agent for liver and paramagnetic Gd (III)-chelate as T 1 contrast agent for all organs. In this work, weak ferromagnetic kale-like and SPM cabbage-like Ni 3 S 2 @Ni hybrid archite…
A new Dy(III) complex, [KDy(sbtc)(H2O)2]·2H2O (1) (KH3sbtc: 5-sulfo-1,2,4benzenetetricarboxylic acid potassium salt), has been synthesized by solvothermal reaction of Dy2O3 and KH3sbtc, and characterized by single crystal X-ray diffraction studies, elemental analysis, and FTIR. Single crystal X-ray diffraction reveals…
This article demonstrates the practical applicability of a method of modelling shape memory alloys (SMAs) as actuators. For this study, a pair of SMA wires was installed in an antagonistic manner to form an actuator, and a linear differential equation that describes the behaviour of the actuator's generated force rela…
ABSTRACT This study evaluated the releasing performance of tara tannin, a cocktail of plant polyphenols, incorporated in submicron fiber, produced by the electrospinning process. Polylactic acid was used as a polymer matrix that carried two loading levels of tara tannin, 14.3 and 22.3% dry weight in the final product.…
Exposure of hydrocarbons (HCs) and particulate matter (PM) under certain real-world operating conditions leads to carbonaceous deposit formation on V-SCR catalysts and causes reversible degradation of its NOx conversion. In addition, uncontrolled oxidation of such carbonaceous deposits can also cause the exotherm that…
The practical application of heat recovery using thermoelectrics requires the realization of reasonable cost effectiveness. Therefore, a thermoelectric generator (TEG) structure that can compatibly increase efficiency and reduce cost was investigated with the aim of enhancing cost effectiveness. To increase efficiency…
Degradation of the deNOx performance has been found in in-use heavy-duty vehicles with a urea-SCR system in Japan. The causes of the degradation were studied, and two major reasons are suggested here: HC poisoning and deactivation of pre-oxidation catalysts. Hydrocarbons that accumulated on the catalysts inhibited the…
The future emission legislations for diesel passenger cars are likely to include more dynamic test cycles than we have today, such as the World harmonized Light duty Testing Cycle (WLTC) and Real Drive Emissions (RDE) in the EU and very challenging SULEV legislations in the USA. In order to meet these emission legisla…
