Based on sediment cores and geophysical data collected from Petermann Fjord northern Nares Strait, NW Greenland, an Arctic ice shelf facies is presented that distinguishes sub pro environments. Sediment were sites beneath the present day Ice Tongue (PIT) in deglacial sediments of Strait with a focus understanding glacial oceanographic history over last 11,000 cal yr BP. The modern laminated dev...

One of the main concerns of the mining industry is to determine ultimate pit limits. Final pit is a collection of blocks, which can be removed with maximum profit while following restrictions on the slope of the mine’s walls. The size, location and final shape of an open-pit are very important in designing the location of waste dumps, stockpiles, processing plants, access roads and other surfac...

Pavlovian conditioned stimuli can influence instrumental responding, an effect called Pavlovian-instrumental transfer (PIT). During the last decade, PIT has been subdivided into two types: specific PIT and general PIT, each having its own neural substrates. Specific PIT happens when a conditioned stimulus (CS) associated with a reward enhances an instrumental response directed to the same rewar...

CMC polymer is used as an additive to decrease water loss and mud-cake-thickness in mud drilling. In this study, the effect of CMC and CMC nanoparticles on water loss and mud-cake-thickness in mud drilling is investigated. CMC nanoparticles are made by using of ball milling and their size is measured by Particle size analyzer. CMC and CMC nanoparticles which were prepared by Hamilton batch mixe...

In the Bayer process of extraction of alumina from bauxite, the insoluble product generated after bauxite digestion with sodium hydroxide at elevated temperature and pressure is known as ̳red mud‘ or ̳bauxite residue‘. Enormous quantity of red mud is generated worldwide every year posing a very serious and alarming environmental problem. This paper describes the production and characterization ...

There is little question that current role-playing MUD systems provide entertainment for their users. Nevertheless, experience with these systems, however entertaining, often falls short of the compelling, rich and varied experiences we associate with dramatic art. This limitation is in part due to the nature of control in MUDs. Control within a MUD is, by de nition, distributed; unlike convent...

An investigation was conducted to estimate approximate production and assess the marketing of mud crab in the south-western region of Bangladesh. Crab culture was done by hardening and fattening collected from the natural source. Most of the fattening farms were 0.2 to 2 acres. Fattening and hardening period varied from 10 to 30 days. The Sundarban mangrove, tidal rivers, estuaries, canals, shr...

Based on the minimum mean squared error (MMSE) between the data stream and the linear combiner output, a new multiuser detection (MUD) algorithm that combines space–time (ST) processing and antenna array on directsequence CDMA signals is proposed. The proposed ST-MUD algorithm is proved to be equivalent to two existing MMSE-based ST-MUD algorithms, and the theoretical BER performances for all t...
