Pit Latrines and Groundwater Contamination Negative Impacts of a Popular Sanitation Method Worldwide an estimated 1.77 billion people use pit latrines as their primary mode of sanitation. With the prevalence of pit latrine use growing in developing countries, there is heightened concern about the negative impacts on drinking water. A new review assesses the known and measured environmental heal...
Tree uprooting creates multiple microsites that can be effective on soil heterogeneity. In order to investigate the soil features in pit and mound location, twenty hectare areas of Tarbiat Modares University Experimental Forest Station studied that is located in Mazandaran province, in the north of Iran. Numbers of thirty four uprooted trees were found in study areas. Five microsites were con...
Noise produced by blast waves can be a problem, especially when an explosion occurs near populated areas. As one means of reducing the blast noise, the explosive is detonated in a pit, a space closed at the bottom and sides, open at the top. A two-dimentional finite difference model was used to simulate such an explosion in a pit and to determine to what extent the blast wave was attenuated. Th...
ultimate limits of an open pit, which define its size and shape at the end of the mine’s life, is the pit with the highest profit value. a number of algorithms such as floating or moving cone method, floating cone method ii and the corrected forms of this method, the korobov algorithm and the corrected form of this method, dynamic programming and the lerchs and grossmann algorithm based on grap...
TRPA1 is a calcium ion channel protein recently identified as the infrared receptor in pit organ-containing snakes. Therefore, understanding the molecular evolution of TRPA1 may help to illuminate the origin of "heat vision" in snakes and reveal the molecular mechanism of infrared sensitivity for TRPA1. To this end, we sequenced the infrared sensory gene TRPA1 in 24 snake species, representing ...
The Pavlovian-to-instrumental transfer (PIT) paradigm probes the influence of Pavlovian cues over instrumentally learned behavior. The paradigm has been used extensively to probe basic cognitive and motivational processes in studies of animal learning. More recently, PIT and its underlying neural basis have been extended to investigations in humans. These initial neuroimaging studies of PIT hav...
PiT-1 and PiT-2 are related multiple transmembrane proteins which function as sodium-dependent phosphate transporters and as the cell receptors of several oncoretroviruses. Two copies of a homology domain that is found in distantly related species assign these proteins to a large family of phosphate transporters. A current membrane topology model of PiT-1 and PiT-2 predicts 10 transmembrane dom...
BACKGROUND The POU class 1 homeobox 1 transcription factor (POU1F1, also known as Pit-1) was reported to be associated with tumor progression and metastasis. The purpose of this study was to evaluate the prognostic value of Pit-1 in breast cancer patients. MATERIAL AND METHODS The relative expression levels of Pit-1 in breast cancer patients were detected by quantitative real-time PCR (qRT-PC...
A new type of monoclonal antibody (mAb)-based, highly specific phototherapy (photoimmunotherapy; PIT) that uses a near infrared (NIR) phthalocyanine dye, IRDye700DX (IR700) conjugated with a mAb, has recently been described. NIR light exposure leads to immediate, target-selective necrotic cell death in vitro. Detecting immediate in vivo cell death is more difficult because it takes at least 3 d...
PIT-2 is a type III sodium phosphate cotransporter and the receptor for amphotropic murine leukemia viruses. We have investigated the expression and the functions of a tagged version of PIT-2 in CHO cells. PIT-2 remained equally abundant at the cell surface within 6 h following variation of the phosphate supply. In contrast, the efficiency of phosphate uptake and retrovirus entry was inversely ...
