Abstarct Despite a broad application of ureolytic bacteria in many bioremediation and biocementation processes, very limited studies have reported their transport retention behaviors under various physical–chemical–biological conditions. In this study, we report Sporosarcina pasteurii saturated sand, based on series column breakthrough experiments different conditions including ionic strengths ...

Palm shell is a waste from palm oil production which shaped like with hard layer character that aims to protect the kernels. The addition of shells concrete an innovation and breakthrough in more productive use waste. In this study, percentage was used, among others, 0%, 7% 14% by weight cement variations water factor (FAS) 0.35, 0.45 0.50. test object used cube (15 x 15 15) cm total 9 objects ...

The objective of this work was to evaluate the transport of Escherichia coli cells in undisturbed cores of a brown leached soil collected at La Côte St André (France). Two undisturbed soil cores subjected to repeated injections of bacterial cells and/or bromide tracer were used to investigate the effect of soil hydrodynamics and ionic strength on cell mobility. Under the tested experimental con...

Biliary tract cancer (BTC) are highly aggressive and fatal malignancies. As one of the leading cause death in Republic Korea, BTC amoung various malignancies has been major public health concerns country. Although BTCs, including intrahepatic, perihilar, distal cholangiocarcinoma, relatively low-incidence compared to other cancer, but they represent a problem endemic areas like Korea Asia contr...

Pancreatic and biliary tract cancers (BTCs) are associated with extremely poor prognoses due to patients frequently presenting at an advanced stage, limited treatment options lack of screening programmes. Treatment for these malignancies may involve a 5-fluorouracil (5-FU)-based chemotherapy regimen. requires Dihydropyrimidine dehydrogenase (DPD) catabolism. deficiency occurs gene (DPYD) mutati...

Polydisperse particles are ubiquitous in both the natural and engineered environment, precise prediction of transport capture polydisperse a saturated medium is crucial. Several efforts (Yao model, RT TE MPFJ NG MHJ MMS model) were developed to obtain accurate correlation equations for particle probability (single-collector removal efficiency), but applicability existing models entire porous re...

introduction: preferential flow is one of the major processes influencing the rapid movement of pollutants to ground water.  macropores created by plant roots provide pathways for rapid transport of pollutants in a soil profile. the growth of plant roots into soil causes creation of big pores that improve water movement and solute transport through soil profile. field soils or undisturbed soils...

The introduction of “smart” tracer techniques in recent years has provided new ways to investigate sediment-water interactions and microbial activity stream corridors. In this study, the formulation STIR model (Marion et al., 2008) is extended represent transport transformation Resazurin-Resorufin smart tracers, an object-oriented toolbox, STIR-RST, presented for evaluation calibration. STIR-RS...

Vegetative buffers have shown promising results in reducing runoff volume, sediment, nutrients, and manure-borne contaminants from agricultural fields. Although these vegetative buffer systems been extensively tested field plot-scale studies that utilize either natural or simulated rainfall, of such under highly controlled conditions the laboratory limited. Here, we present development a new sy...
