Abstract Objective: Mycobacterium tuberculosis (MTB) is an obligate aerobe bacterial pathogen. Here, the citrate synthase (CS) family, an important component of aerobic respiration, was investigated in MTB. Methods: MTB genome was analyzed in silico to reveal the members of CS family. The nucleotide and amino acid seq…
When constructing large-span metal domes different methods of installation are used, which depend on geometry schemes of the frames and their construction solution. The frames of such domes consist of a lot of structures. During assembling large number of structures with different spatial orientation are joined togeth…
The optical layout of an objective with relative aperture 1∶1 and two viewing fields, based on a six-lens arrangement that contains no aspheric lenses, is considered in this article. This is used in thermal viewers based on microbolometric photodetector arrays. The design parameters of the optical layout and the calcu…
Tujuan utama dari optimasi desain ini adalah untuk meningkatkan kualitas dari mesin bubut yang akan dibuat BMEPPO-BBPT. Dengan tetap menggunakan material Gray cast iron (FC25) serta menekan jumlah material yang di butuhkan dalam pembuatan bed bubut tersebut tetapi menghasilkan bentuk desain Slant Bed bubut CNC yang op…
Carbon fibre reinforced silicon carbide (C/SiC) brake materials are new highly competitive brake materials. They possess a series of outstanding advantages such as high strength, low density, good high temperature resistance, excellent friction properties, low wear rate and long life. Up to now, it has been equipped i…
Due to concerns about the climate change combined with the decrease of fossil resources, the use of CO2 as a C1 feedstock for producing added value chemicals and materials has become a huge challenge in academic laboratories and in industry. The coupling of CO2 with epoxide has emerged as one of the most promising way…
The work presented in this thesis consists of three distinct areas, each of which is explored using solution-phase femtosecond transient electronic (ultraviolet/visible) absorption spectroscopy. The first area is the effects of the environmental surroundings on the intrinsic photodynamics of a molecule. The second are…
Penelitian bertujuan untuk mendapatkan hasil yang terbaik terhadap ukuran butir serbuk tulang terhadap sifat mekanik matrial komposit serbuk tulang yang baik pada pengujian kekerasan dan pengujian keausan. Dalam penelitian ini serbuk tulang kambing berfungsi sebagai penguat yang di gabungkan resin epoxy dan diharapkan…
V$_{2}$O$_{5}$ and K$_{2}$O-V$_{2}$O$_{5}$ impregnated MgAl$_{2}$O$_{4}$ catalysts were prepared and tested for the oxidative dehydrogenation of propane. The as-synthesized catalysts were characterized by using the XRD, BET, NH$_{3}$-TPD, TPR, and XPS methods. The catalytic tests were performed in a fixed bed tubular…
Abstract \nSilicon Nanoparticles (SiNPs) are non-toxic materials particularly suitable for various biomedical applications. They exhibit unique optical properties for use in bioimaging and diagnostic applications. To exploit these aspects, this thesis explores the synthesis, characterisation and biological activity of…
D is an analytical test commonly used by the pharmaceutical industry to guide both formulation design and drug product quality control. When considering the development of a dissolution method, two main goals must be considered: 1) ensure consistent lot-to-lot quality for commercial products; 2) be suitable as QC tool…
In the present paper, the complex variable method is applied to derive exact expressions for Gaursat functions, for the first and second fundamental problems. Here, an infinite elastic plate weakened by a generalized curvilinear hole C is considered, in the two dimensional problems, in the theory of elasticity. The ho…
This paper deals with the concrete made of wastes which are ecofriendly so called as green concrete.
Current estimates suggest that the United States loses over $220 billion dollars due to corrosion each year. The research results from this project further Ohio Department of Transportation's (ODOT's) effort to implement a corrosion prevention strategy that will increase public safety by preventing unexpected snow and…
L’utilizzo di nanomateriali, ovvero una nuova classe di sostanze composte da particelle ultrafini con dimensioni comprese fra 1 e 100 nm (American Society for Testing Materials - ASTM), è in costante aumento a livello globale. La particolarità di tali sostanze è rappresentata da un alto rapporto tra la superficie e il…
In recent years, the demand for using magnesium (Mg) alloys has significantly increased in several industrial fields. Due to their favorable strength/weight ratio thus Mg alloy demonstrating a valid replacement for aluminum alloys and High Strength Steels particularly for the production of lightweight parts in aerospa…
Mesoporous carbon materials have been used for numerous applications such as adsorption1, separation2, supercapacitor3 and oxygen reduction reaction (ORR)4 due to their preeminent textural characteristics, high surface area, mechanical stability and mesoporous structure. The properties of mesoporous carbon materials b…

The growing application of high temperature materials, such as gas turbines, chemical reactors and nuclear materials, challenges the researchers to assess the mechanical properties of materials at high temperature (Webster & Ainsworth 1994). In such applications, creep becomes important due to its thermal activated me…
New solid electrolytes with a high rubidium-cation conductivity, which are based on Rb 3 PO 4 with partial substitution of three-charged yttrium, lanthanum, and neodymium cations for Rb + cations, are synthesized and studied. Introduction of M 3+ cations leads to an abrupt increase in the conductivity of rubidium orth…
