) 1- Bi films (0 0.15) has been investigated. Adding Bi to amorphous GeS condensates leads to changes in the mechanism of conductivity and inversion of the conductivity type. Bi-additives reduce the activation energy of photoconductivity and photosensitivity of the GeS films. The changes of the physical properties of…
The structure, elastic constant, Debey temperature and electron distribution of α-Ti2Zr under high pressure are presented by using first-principles pseudopotential method based on density functional theory in this paper. The calculated structural parameters at zero pressure are in agreement with experimental values. T…
A new kind of nanofluids-based on transformer oil is prepared with ZnO nanoparticles synthesized by solvothermal reaction to investigate the influences of adding nanoparticles on electrical conductivity of Transformer oil.The mechanism how temperature and volumetric fraction affect electrical conductivity is also disc…
Liposomes are hollow particles which content is limited to a lipid membrane. They belong to a large family of vesicular (bubble) structures formed by amphiphilic molecules. Liposomes consisting of one or more phospholipid bilayers were first described in the mid 60s. In a relatively short period liposomes transformed…
NacrtakThis paper presents the history and tradition of forestry academic education in Europe.In the last few decades a lot of changes have occurred and forestry academic education has lost a highlevel position in European society and economy.In many European countries, higher education forestry programs are just a pa…
The aim of this work is to evaluate the mechanical performance of cement mortar composites reinforced with various percentages of cellulose fibres. Results indicated that for low content of fibres there is a high adhesion between the cement matrix and the fibres and, consequently, the fracture of the composite under f…
The dosimetric characteristics of prepared MgB4O7 doped with Dy have been studied using the thermoluminescence (TL) technique. The TL was observed at the most intense temperature of 187±2 oC that is applied on varied Dy concentration. The response recorded was linear with gamma doses in the range from1 Gy up to 2 kGy…
In the petroleum industry precipitation of scale onto the inner walls of hydrocarbon pipelines poses a significant challenge as, unless treated appropriately, deposits such as sulfate and carbonate scales reduce the overall flow area and even lead to blockage of entire sections of the pipework. This may in turn result…
Researchers in nanotechnology are focusing their research towards the development of silver nanomaterial synthesis as they are known to posses inhibitory and bactericidal effects. Resistance towards bacterial infections has emerged in recent years and is a major health hazardous. In the present work attempts were made…
The quest for highly stretchable fabrics with good and lasting handle properties such as absorbance, feel, and comfort has inspired researchers to constantly involve in blending of natural and artificial fibres. One of the commonly used methods of blending is core yarn spinning. Core spun yarn structure consists of tw…
The simulation model has been examined using experimental data obtained from a phosphoric acid plant. The predicted results are in very good agreement with the experimental data with a relative absolute error of less than 4.2%. To solve the simulation model, sequential modular approach (tearing streams employed) is us…
In this research paper, the Sorrel stem fiber was graft copolymerized by vinyl monomeric mixtures that lead to an increase in the percentage grafting with a significant change in physico-chemico-thermal resistance. Miscibility in organic solvents, hydrophobicity was found to increase whereas crystallinity, crystallini…
During the emergence of a new drug it is very important to ensure its systemic bioavailability. Majority of the drugs in the developmental pipelines confronts with the problem of poor solubility; which will result in reduced dissolution rate there by hampering its bioavailability. Here comes the need of liquisolid tec…
In various thermal power plants the combustion of coal results in the release of some natural radioactivity which consequently increases the radioactivity in soil, water and atmosphere around thermal power plants. As the radon in the atmosphere, soil, ground water, oil and gas deposits contributes the largest fraction…
Spruce wood specimens (Picea abies (L.) Karst.) exposed to stepwise tensile load parallel and perpendicular to fiber orientation until failure were monitored simultaneously with in-situ Acoustic Emission (AE) measurement and Synchrotron Radiation X-ray Tomographic Microscopy (SRXTM). The AE method enables high time re…
Solid polymer electrolyte films of poly (vinyl) chloride (PVC) with ammonium trifluoromethane sulfonate (NH4CF3SO3) and ionic liquid, butyltrimethyl ammonium bis (trifluoromethyl sulfonyl) imide (BATS) as plasticizer have been prepared by solution-cast technique. The films were characterized electrically by Impedance…
Since interactive pattern-making technique in Garment CAD has its inherent limitation, some advanced pattern-making ones are intensively studied. This paper reviews state-of-art pattern-making techniques, including pattern generation based on artificial neural network, pattern flattening technique from 3D human or gar…
Ions of inorganic salts are known to affect bubble coalescence via the surface charge density as described by the classical DLVO theory of colloid stability. Our experimental results obtained for monovalent salts of different concentrations show different effects of monovalent anions (F-, Cl-, Br- and I-) and cations…
Grain boundaries can change their misorientation by absorbing lattice dislocations at relatively high temperature under moderate straining. The same phenomenon is believed to occur during severe plastic deformation down to room temperature leaving grain boundaries in the nonequilibrium state. Direct evidence of dynami…
The possibility of liquid forging of 17’ automobile wheels out of the aluminum alloys A356.2 and 6061 was evaluated. The optimization of liquid forging was executed and the pilot technological process of liquid forging of automobile wheels was developed.
