The phosphorus equilibration pattern and rate bctwecn mud and water was the same in natural Jcnkin sampler cores, in artificial cores, and in bottles in which dredged surface mud was packed by centrifuge. Thus any specific natural physico-chemical or bacteriological layering of the surface muds of lakes is relatively unimportant in phosphorus exchange, Phytoplankton or bacterial cells equilibra...

Abstract The oil-based mud is preferred to drill highly technical and challenging formations due its superior performance. However, the inadequate chemical thermal stability of conventional additives have greatly influenced performance at high-temperature conditions. Therefore, it critical design an with that withstand improve nanoparticles emerged as alternative can significantly enhance rheol...

Thumbprint terrain was first recognized in Viking Orbiter data and described as sets of alternating continuous parallel ridges depressions up to several tens kilometres length, with high low albedo respectively. We performed a geomorphological analysis these features using both Context Camera High Resolution Imaging Science Experiment images, well topographic profiles based on Mars Laser Altime...

Received: April 29, 2017 Revised: July 01, 2017 Accepted: August 30, 2017 Abstract: Introduction: Unloading phenomenon happens in the beginning of drilling and is able to change stress state around borehole. This change of stress state causes impact on rock structure and strength, thus affecting the evaluation of wellbore stability. Especially for determining initial mud pressure, unloading is ...

-In this paper, the microstatistic multi-user detection receiver (MSF-MUD) will be introduced. The output of the MSF-MUD is taken as the sign of the multi-channel non-linear transformation of the output of a bank of matched filters (BMF). In the case of the MSF-MUD, this transformation is done by multi-channel conventional microstatistic filter (MCMF). Because the M-CMF theory has not been avai...

We have developed and tested a numerical model for turbulence resolving simulations of dense mud–water mixtures in oscillatory bottom boundary layers, based on low Stokes number formulation the two-phase equations. The resulting non-Boussinesq equation fluid momentum is coupled to transport mud volumetric concentration, giving rise volume-averaged velocity that non-solenoidal, was implemented a...

The discovery of a reo-like virus in cultures of the mud crab Scylla serrata (Forsskål, 1755) is reported here. Since May 2004, in Zhejiang Province, Peoples Republic of China, reo-like virus in mud crabs has reached serious epidemic levels, causing mortality rates exceeding 90%. Beginning in May 2004, moribund crabs from different districts and areas were investigated. By using electron micros...

This paper investigates the Weighted Linear Parallel Interference Cancellation (WLPIC) Multiuser Detection (MUD) scheme with Vertical-Bell Laboratories Layered Space-Time (V-BLAST) signal detection algorithms in uplink Code Division Multiple Access based Multiple Input Single Output (MISOCDMA) system. The Bit error rate performance of WLPIC scheme with V-BLAST signal detection and Conventional ...

Mud volcanoes are solid objects that form on the seafloor due to the emission of gas and fluidized sediment from the earth’s interior [1]. They vary widely in size, can be exposed, proud, or buried, and are of interest to the Navy as sources of active sonar clutter [2]. The long-term goal of this work is to accurately model mud volcano scattering. The final product will make predicting and simu...
