External and internal radiation doses due to alpha activity in Tafila district, Jordan

Tafila district of Jordan is unique in the presence of phosphate mines and hot spa which are the major sources of natural radioactivity. Natural radionuclides transfer from soil to vegetables grown in the region, and become a part of people's food. In this study, 16 soil and vegetable samples from Tafila district were collected from eight locations. External absorbed dose rates were calculated to ...

Strainer

Penglai Huande Steel valve Co., Ltd mainly export Y-type strainer. In Y-type strainer the filter leg connects to the main pipe at a diagonal angle, giving the strainer its "y" shape, and hence its name. This type is commonly used in pressurized lines, steam, liquid or gas, but can also be applied in vacuum or suction situation. Y-type strainers usually have a lower dirt holding capacity ...

Determination of <i>P-Y</i> Curves Using Inclinometer Data

Determination of P-Y Curves Using Inclinometer Data

Derivation of p-y curves from lateral load tests on deep foundations is a tedious and expensive task, requiring large numbers of strain gages along the length of the pile to develop bending moment versus depth relationships. A method is proposed which allows derivation of p-y curves from simple inclinometer data using a least-squares regression technique. Inclinometer measurements can and have ...

Calculation of radiation doses to human organs from consumption of marine fish

In the present work, radiation doses are estimated from the analysis of 40K, 137Cs, 226Ra and 228Ra radionuclides in marine fish of the Bay of Bengal, accumulated in ten different human organs: red marrow, lung, thyroid, lower large intestine, upper large intestine, small intestine, breast, stomach, gonads and bone surface. The lowest equivalent dose is calculated in the thyroid as 2.7×10−3 µSv/y ...

Levels of six antibiotics used in China estimated by means of wastewater-based epidemiology

Due to lack of proper regulation, information about antibiotics consumption in many countries such as China is difficult to obtain. In this study, a simple method based on wastewater-based epidemiology was adopted to estimate their usage in four megacities of China. Six antibiotics (norfloxacin, ofloxacin, sulfamethoxazole, trimethoprim, erythromycin and roxithromycin), which are the most ...

Design of Laterally Loaded Driven Piles Using the Flat Dilatometer

The nonlinear subgrade reaction method (P-y curves) is widely used for the design of laterally loaded piles. This method replaces the soil reaction with a series of independent nonlinear Winkler springs.A preliminary semi-empirical approach for the determination of P-y curves using data obtained from a flat dilatometer test (DMT) is presented and evaluated. A brief description of the equipment, ...

El nuevo marco normatívo en Contaminación de Suelos

La Ley de Residuos 10/1998, en sus artículos 27 y 28, ha constituido hasta enero 2005 la legislación estatal básica existente en materia de protección del suelo frente a su contaminación. Esta regulación adolecía de carencias normativas que hacían inviable su efectiva aplicación. Tras varios años de debate y cerca de una decena de borradores, el Ministerio de la Presidencia, aprueba por fin ...

Water budget analysis and management for Bangkok Metropolis, Thailand

The water budget of the Bangkok Metropolis system was analyzed using a material flow analysis model. Total imported flows into the system were 80,080 million m3 per year (Mm3 y–1) including inflows from the Chao Phraya and Mae Klong rivers and rainwater. Total exported flows out of the system were 78,528 Mm3 y–1 including outflow into the lower Chao Phraya River and tap water (TW) distributed ...

Estimation of erosion rate in a small catchment of Loktak wetland, India, using lead-210 (210Pb) technique

Loktak Lake, one of the largest freshwater wetlands in the northeastern India, is under severe pressure due to many reasons-the main being increased siltation from the degraded catchment area. In the present study Nuclear Technique [Lead-210 (210Pb) Technique] has been applied to estimate soil erosion rates in the catchment of the lake. The erosion rates of the various land uses in the catchment ...

A model for simulating atmospheric dispersion in low-wind conditions

A practical model for low-wind conditions was derived by integration of an instantaneous three-dimensional Gaussian puff equation, in which wind speed was assumed to be zero and standard deviations of a smoke (σy and σz) were expressed as a linear function of the dispersion time. When the plume spreads σy and σz were assumed to be linear functions of dispersion time, the ...

Mind bomb-1 is essential for intraembryonic hematopoiesis in the aortic endothelium and the subaortic patches

Intraembryonic hematopoiesis occurs at two different sites, the floor of the aorta and subaortic patches (SAPs) of the para-aortic splanchnopleura (P-Sp)/aorta-gonad-mesonephros (AGM) region. Notch1 and RBP-j are critical for the specification of hematopoietic stem cells (HSCs) in Notch signal-receiving cells. However, the mechanism by which Notch signaling is triggered from the Notch ...
