Pit latrines can provide improved household sanitation, but without effective and inexpensive emptying options, they are often abandoned once full and may pose a public health threat. Emptying techniques can be difficult, as the sludge contents of each pit latrine are different. The design of effective emptying techniques (e.g., pumps) is limited by a lack of data characterizing typical in situ...

The hydraulic resistance of pit membranes was measured directly in earlywood vessels of Fraxinus americana and Ulmus americana. The area-specific resistance of pit membranes (r(mem)) was higher than modeled or measured values obtained previously for hardwood species, with r(mem) of 5.24 × 10(3) MPa·s·m(-1) for Fraxinus and 2.56 × 10(3) MPa·s·m(-1) for Ulmus. The calculated resistance of pit can...

BACKGROUND A pit latrine is the most basic form of improved sanitation which is currently used by a number of people around the globe. In spite of the wide spread use, known successes and advantages associated with pit latrines, they have received little attention in form of research and development. This review focuses on the usage and performance (filling, smell and insect nuisance) of pit la...

The POU transcription factor Pit-1 activates members of the prolactin/growth hormone gene family in specific endocrine cell types of the pituitary gland. Although Pit-1 is structurally conserved among vertebrate species, evolutionary changes in the pattern of Pit-1 RNA splicing have led to a notable "contraction" of the transactivation domain in the mammalian lineage, relative to Pit-1 in salmo...

sore has appeared among the class of people (not necessarily poor) who, during a heavy rainy season, walked in mud and worked in marshy localities, barefooted. Forty-five inches of rain, mud and marshy conditions?and Naga sore were not previously known to this place. The same thing happened in Benares last summer, when heavy rainfall flooded the area, resulting in mud and marsh so that Naga sor...

Conventional Multi-User Detection (MUD) algorithms for the Multi-Input, Multi-Output-Orthogonal Frequency Division Multiplexing (MIMO-OFDM) system fail to consider the detection performance and algorithm complexity simultaneously. To address this problem, a new Joint Intelligent MUD (JI-MUD) algorithm that aims to improve the MUD performance of the MIMO-OFDM system and to reduce the complexity ...

Macular detachment causes visual deterioration in 25-75% of patients with congenital optic disc pit. A number of treatment options have been reported to manage the macular detachment in optic pit. An optic disc pit represents a defect in the lamina cribrosa; theoretically, an ideal procedure to treat optic pit associated macular detachment would be one that prevents the flow of fluid across the...

A critical component in determining post-mining pit water quality is knowledge of groundwater fluxes, both as the pit fills and after steady state conditions have been reached. Simulations of the filling of an open pit in Crescent Valley, Nevada, were made to generate inputs for pit lake chemistry predictions. The simulations show that the water table recovery is most rapid immediately after pu...

BACKGROUND/AIM The aim of this study was to examine the relationship between narrow-band imaging (NBI) magnifying observation using the surface pattern as the main evaluation criterion and pit pattern diagnosis on the basis of magnifying observation using a dye in relation to the characteristics of colorectal tumors according to their morphologies. METHODS In this study, NBI observation and p...
