Dynamic finite versioning (DFV) schemes are an effective approach to concurrent transaction and query processing, where a finite number of consistent, but maybe slightly out-of-date, logicalsnapshots of the database can be dynamically derived for query access. In DFV, the storage overhead for keeping additional versions of changed data to support the logical snapshots and the amount of obsolesc...

Many hydrological studies of forested ecosystems focus on the study of the forest canopy and have partitioned gross precipitation into throughfall and stemflow. However, the presence of forest litter can alter the quantities of water available for soil infiltration and runoff. Little information exists regarding the value of storage and drainage parameters for litter layers. Vegetation paramete...

BACKGROUND The stability of ethanol was investigated in blood specimens in glass or plastic evacuated tubes after storage in a refrigerator at 4 °C for up to 12 months. METHODS Sterile blood, from a local hospital, was divided into 50 mL portions and spiked with aqueous ethanol (10% w/v) to give target concentrations of 0.20, 1.00, 2.00 and 3.00 g/L. Ethanol was determined in blood by headspa...

[1] Despite the importance of mountainous catchments for providing freshwater resources, especially in semi-arid regions, little is known about key hydrological processes such as mountain block recharge (MBR). Here we implement a data-based method informed by isotopic data to quantify MBR rates using recession flow analysis. We applied our hybrid method in a semi-arid sky island catchment in so...

Obstacles in the learning process carried out by subject teachers and students of SMA Chandra Kusuma School, North Jakarta, because document storage is still low internet access slow. Multiple linear regression algorithm to determine relationship between cloud computing variables on variables. Simultaneously F test results are 15.387 coefficient determination 36.30% so that there a significant ...

The study aims to determine the hydrologic properties of an aquifer Malamawi Island in terms transmissivity, storage coefficient, and specific discharge using Theis method. was conducted March 2015. 4 inches 2- boreholes are drilled two different locations (Diki Santa Barbara villages) identify lithologic properties. A pumping test performed for forty-five (45) minutes and, drawdowns observed f...

potato (Solanum tuberosum L.) genotypes exhibit significant variation for chip color across different storage regimes. Lines that maintain light chip color after long postharvest storage durations and low storage temperatures are desirable to the potato industry. Since storage regimes vary among growers and processors, lines that exhibit stable chip performance across various storage regimes ha...

J.E. Braun, Ph. D., P.E. Purdue University This paper describes the development and validation of an improved mechanistic model for predicting the thermal performance of an area constrained ice storage system. Experimental data was obtained from a fully instrumented thermal storage test cell located within the Herrick Laboratories, Purdue University. Results for both charging and discharging cy...

The excellent properties of graphene phase change nanocomposite made it have potential application value in the field heat storage materials, which was expected to achieve integration transfer and storage. In order enhance thermal performance paraffin energy storage, structure models n-octadecane three kinds graphene/n-octadecane composites were established. Molecular dynamics method used study...
