A −100 kV, 25 A DC power supply is employed for biasing TH 2089 klystron amplifier of 1 MW, 352.2 MHz RF test setup developed at Raja Ramanna Centre for Advanced Technology (RRCAT), Indore. Input to this power supply is taken directly from 3 phase, 11 kV line through step start unit to minimize inrush current. Issues…
From an electrical engineering point of view insulators plays a crucial role. It is used as a basic element in overhead transmission lines and in distribution. Therefore, it is very much essential for insulator string to relate the potential distribution and electric field distribution of the respective ideal string a…
In the present research porous Mg-Zn scaffolds with different Zn amount and porosities were synthesized by powder metallurgy process as potential degradable materials for orthopedic applications. The microstructures, composition, mechanical properties and in vitro biodegradability of the scaffolds were investigated. O…
Wideband Tin oxide (SnO2) has drawn a great deal of attention due to its excellent properties in a gas sensing material, photovoltaic cells, fuel cells etc. In the present work SnO2sample is synthesized by Sol-gel route. XRD study has been conducted for determination of crystallinity and the structure of SnO2sample. T…

Bu alma AISI 304 kalite paslanmaz elik zerinde bir U-bkm ile gerilim yaratlarak farkl seyreltilerdeki asidik ortamlarda meydana gelen gerilim…
One of the serious problems with modern electrical loads is harmonics, which is generated from nonlinear loads. Harmonics can lead to excessive heat and noise in the loads and create a large amount of energy losses either in transmission systems or distribution systems. Compensation of these harmonics substantially im…
Kinetics and mechanism of esterification of dichloromaleic anhydride with C 1 –C 4 alcohols in the presence of zeolitic catalysts have been studied. The stage-by-stage Langmuir–Hinshelwood mechanism of heterogeneous catalysis at acidic active surface sites of zeolites has been suggested. The kinetic model has been ela…
Haemophilus influenzae type b (Hib) vaccine is made up from its capsular polysaccharide (PRP). Low productivity of the polysaccharide during cell growth increases the final cost of this vaccine. Hib achieves low levels of cellular concentration in vitro due to the inhibition caused by acetate. The Akaike Information C…
The derivatives of methyl 2,4-dihydroxybenzoate containing fragments of different organic acids in position 4 have been synthesized. Their mesomorphic properties have been investigated. Lanthanide complexes of the prepared compounds have been obtained. Their spectral properties have been studied.
The paper shows that the use of 232 Th as a fertile isotope instead of 238 U and the main fissile isotope 233 U instead of 239 Pu, the use of heavy water instead of light water as a coolant, and its dilution with light water during the VVER-type reactor run ensure the fuel self-sufficiency in active isotopes, particul…
Core excess reactivity and shutdown margin are important parameters for safe and reliable operation of a nuclear reactor. In this experiment, core excess reactivity and shutdown margin were determined at different power levels of the BTRR. The results were then checked to ensure that the core excess reactivity and shu…
Methods for calculating the heat and neutron transport in structural elements of nuclear and fusion power devices are considered in the framework of statistical modeling and physical neutron kinetics based on the cross sections of interaction of neutrons with matter. Statistical modeling makes it possible to establish…
Control of the photogenerated electrons transfer rate from TiO 2 nanoparticles to MoS 2 nanosheets is an effective method for modulating the optical property of 2‒3 layers MoS 2 nanosheets. In this paper, core-shell structure MoS 2 /polyvinyl benzyl mercaptan sub-microspheres (PS) with vertical 2‒3 layers MoS 2 nanosh…
Application of foam in EOR, increases macroscopic sweep efficiency via awesome increscent of mobility control. Macroscopic manifestation of foam application performance in porous media is complex process that involves several interacting microscopic foam events. Stability as an important factor in foam injection withi…
Solder paste is a suspension of metal powder in the flux medium which is used for assembling various electronic components on printed circuit boards (PCBs). To apply solder paste on PCB, various methods like stencil printing, dispensing, dipping, pin transfer etc. are used as per suitability in a particular applicatio…
In this study, glass fibers are fabricated via a continuous spinning process using manganese slag, steel slag, and silica stone. To fabricate the glass fibers, raw materials are put into an alumina crucible, melted at 1550 °C for 2 hrs, and then annealed at 600 °C for 2 hrs. We obtain a black colored glass. We identif…
Abstract It has been shown that platinum atoms evaporation on graphene covering molybdenum carbide Mo2C at T = 1000 K causes platinum intercalation into the graphene. In such a case, a continuous multilayer platinum film grows under the graphene, which makes it possible to distinguish graphene-related components in th…
ABSTRACT The potential14C (carbon-14, radiocarbon) flux from disposal of14C containing waste into air is compared with the natural14C emanation rate from soil in order to put the14C hazard potential from disposal of this waste in perspective with the14C exposure from cosmogenic origin. Chemical corrosion of neutron ir…
