Lepidoptera feed at mud puddles, dung, and carrion in a behavior known as puddling. Sodium and sometimes protein are feeding cues, are actively collected, and play a potentially important role in lepidopteran nutritional and mating ecology. We showed that montane butterßy species have feeding preferences among mud, herbivore dung, and carnivore dung, and that these preferences differed among bu...

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...

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...

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...

When naval mine-hunting sonars and side-scan surveying sonars operating at 20~60 kHz are working in shallow coastal waters, the visco-thermal absorption of sound by suspended mud in the water may greatly decrease their detection properties. This kind of water is also characterized as turbid seawater. However, the research on measuring the coefficient of sound absorption in turbid seawater has l...

This paper presents a wellbore-stability study of the San Andreas Fault Observatory at Depth (SAFOD) research borehole located near Parkfield, California, USA. In the summer of 2005, the SAFOD borehole was drilled successfully through the active trace of the San Andreas Fault (SAF) in an area characterized by fault creep and frequent microearthquakes. In this study, we report how the analysis o...
