Shale is one of the rocks that often causes drilling problems because shale tends to swell or when in contact with mud filtrate, mainly water-based Water-base Mud (WBM). This study aims determine how performance Oil-base (OBM) based on Crude Coconut Oil (CCO) overcoming swelling problem. The methodology used consists simulation and cutting analysis X-Ray Diffraction (XRD) laboratory. series act...

Groundwater and harvested rainwater represent the only conventional freshwater resources in United Arab Emirates (UAE). Wadi Al Bih, UAE, are sustainable due to low exploitation rate for domestic agricultural purposes. Thus, groundwater depletion this area is far less than other parts of country. The Bih very important achieving water security UAE. Therefore, possible measures increasing rechar...

This paper critically examines 48 digital news updates to six New York Times online articles collected through 181 captures via the Internet Archive’s Wayback Machine (WBM), a web scraping tool, pertaining federal military and local police responses Portland protests published in headlines, sources, quotes, hyperlinks, order of information presented, articles’ main thrusts meaning. Through this...

Shipping companies and maritime organizations want to improve the energy efficiency of ships reduce fuel costs through optimization measures; however, accurate consumption prediction is a prerequisite for conducting measures. In this study, white box models (WBMs), black (BBMs), gray (GBMs) are developed based on sensor data. GBMs have great potential ship consumption, but lack interpretability...

Lo et al. (2007) propose that all endobacteria of arthropods and nematodes commonly called Wolbachia be formally declared as Wolbachia pipientis. Part of their reasoning is based on the difficulty of assigning the strains to monophyletic species due to the lack of an appropriate outgroup and the fact that to name arthropod strains after the species they infect would be unwieldy because of the h...

36 JPT • NOVEMBER 2014 To estimate reserves, optimize well recovery, and place future development wells more accurately, operators require increasingly detailed understanding of complex oil and gas reservoirs. Highresolution geological data from the borehole—core samples and wireline microresistivity images—are essential to fully characterize reservoir architecture, guide and constrain reservoi...

In Web stream processing, there are queries that integrate Web data of various velocity, categorized broadly as streaming (i.e., fast changing) and background (i.e., slow changing) data. The introduction of local views on the background data speeds up the query answering process, but requires maintenance processes to keep the replicated data up-todate. In this work, we study the problem of main...

The solution of unbounded Helmholtz problems is the subject of substantial research. If these problems are to be solved using a domain-based discretisation technique like the finite element method (FEM), the computational domain has to be truncated to a bounded region. The unbounded nature of the problem exterior to this truncation is simulated by an appropriate condition on the truncation. A c...

Water conservation is an essential indicator of the hydrological regulation capacity terrestrial ecosystems. At regional scale, water ecosystem typically assessed using balance model (WBM). However, estimation runoff depth relies heavily on rainfall data and coefficient look-up table, which introduces uncertainties in assessment results. To address this issue, study constructed a new method for...
