compressibility factor and viscosity of natural gasses are of great importance in petroleum and chemical engineering. to calculate the natural gas properties in the pipelines, storage systems and reservoirs, the exact values of gas compressibility factor and viscosity are required. a new method that allows accurate determination of compressibility factor and gas viscosity for all types of: swee...

rock has been advantageously employed in hydraulic structures such as rockfill dams, gabion weirs and drain works. one rockfill dam applications can be flood control in wa-tershed management. the objectives of building rockfill detention dams are flow storage for a specific period and lowering of the outflow hydrograph. as this type of dam consists of coarse particles, seepage flow will deviate...

Managing and utilizing storage resources have resulted in complexity because of the heterogeneous nature of storage infrastructures. Paper elucidates that Virtual Private Network created in the Wireless Public Network would have implemented virtualization and would result in enhancement of productivity and efficient management of storage infrastructures. Proof is generated that Virtual environm...

lipid oxidation was studied in m. longissimusdorsiand m. semimembranosusin male lambs of northeastern bulgarian fine wool breed and cross of this breed with ile de france, reared indoors and on pasture. the oxidation of the lipids was determined by quantification of thiobarbituric acid reactive substances (tbars), formed during the storage of the muscles at 4 ˚с until 6th dayand -20 ˚с until 90...

The wear leveling is a critical factor which significantly impacts the lifetime and the performance of flash storage systems. To extend lifespan and reduce memory requirements, this paper proposed an efficient wear leveling without substantially increasing overhead and without modifying Flash Translation Layer (FTL) for huge-capacity flash storage systems, which is based on selective replacemen...

Since its introduction in 1971, the B-tree has become the dominant index structure in database systems. Conventional wisdom dictated that the use of a B-tree index or one of its descendants would typically lead to good results. The advent of XML-data, column stores, and the recent resurgence of typed-graph (or triple) stores motivated by the Semantic Web has changed the nature of the data typic...

Transfusion of red blood cells (RBCs) is an effective therapy in surgery and critical care. Comparing to fresh RBCs, the therapeutic effect of stored RBCs is greatly limited because of its loss of NO during storage, which leads to vasodilatation dysfunction upon transfusion. So far, there is no effective solution to this problem. Here, we summarize the protective effects of Haptoglobin (Hp) in ...

Cinnamomum burmanii L, a cinnamon plant developed in Indonesia, requires high-quality seeds, yet propagation faces challenges due to limited access quality seeds at the appropriate time. This study aimed determine viability of from level maturity and size. The experimental design used this was randomized completed block with factorial pattern, first-factor treatment being namely: 1) K1 (purple)...
