This paper describes the liquid scintillator veto system for COSINE-100 dark matter experiment and its performance. The detector consists of eight NaI(Tl) crystals immersed in 2200~L linear alkylbenzene-based scintillator. tags between 65 75\% internal $^{40}$K background 2--6 keV energy region. We also describe model scintillator, which is primarily used to assess calibration threshold.

Abstract Biotic stress caused by pests on citrus trees has become a major problem for ecologists around the world, hence need to develop ecological approaches surmount this stress. To evaluate effectiveness of diverse control methods pest Panonychus citri and its predators, Euseius stipulatus , Phytoseiulus persimilis Typhlodromus sp. Different treatments were applied in orchards planted Citrus...

Aromatic sulfonates (R-SO(3)(-)) can be used as sulfur sources by sulfate-starved bacteria in laboratory cultures and the corresponding phenols are excreted from the cells. The present study was conducted to demonstrate whether such desulfonation reactions also occur in sulfate-leached agricultural soil, where desulfonation of organic sulfur compounds may have agronomic importance as a S source...

in this paper the photocatalytic degradation of the anionic surfactant, linear alkylbenzene sulfonicacid (labsa) was investigated using uv radiation in the presence of tio2. our findingsdemonstrate that various parameters exert their individual influence on the photocatalytic degradationof surfactant in wastewaters. the mentioned parameters have been categorized as follow: the initialph of the ...

An efficient metal free protocol has been developed for the synthesis of benzylic esters via a cross dehydrogenative coupling (CDC) involving alkylbenzene(s) as a self- or as a cross-coupling partner(s) via the intermediacy of Ar-COOH and the benzylic carbocation obtained from the other half of the alkylbenzene; both symmetrical as well as unsymmetrical esters can be prepared using Bu4NI and TBHP.

Linear alkylbenzene sulfonate (LAS) is widely used in the formulation of domestic and industrial cleaning products, the most synthetic surfactants used worldwide. These products can reach water bodies through the discharge of untreated sewage or non-effective treatments. This study evaluates the ability of the microorganisms found in the Tiete river sediment to degrade this synthetic surfactant...

This paper brings together over 250 published and unpublished studies on the environmental properties, fate, and toxicity of the four major, high-volume surfactant classes and relevant feedstocks. The surfactants and feedstocks covered include alcohol sulfate or alcohol sulfate (AS), alcohol ethoxysulfate (AES), linear alkylbenzene sulfonate (LAS), alcohol ethoxylate (AE), and long-chain alcoho...
