Freshwater prawns, Macrobrachium lamarrei (Crustacea-Decapoda) were subjected to static subacute exposure (0.755 mg/l) of detergent, Linear Alkyl Benzene Sulphonate (LAS) (25% 96h LC50) for 10,20 & 30 days. Hepatopancreas showed pronounced changes like vacuolization, hypertrophy, hyperplasia and degenerative leading almost complete loss histoarchitecture after days exposure. Peculiar cell shedd...

In the title compound, C(28)H(50)S(2), the alkyl chains adopt a fully extended all-trans conformation and each of them is almost perfectly planar. One of the alkyl chains is coplanar with the benzene ring and the other is twisted out of the benzene ring plane; the C-C-S-C torsion angles are 176.4 (2) and 80.8 (3)°. In the crystal structure, an inter-molecular S⋯S inter-action [3.2123 (13) Å] li...

The effect of molecular architecture of a surfactant, particularly the attachment position of benzene sulfonate on the hexadecane backbone, at the decane-water interface was investigated using atomistic MD simulations. We consider a series of surfactant isomers in the family of alkyl benzene sulfonates, denoted by m-C16, indicating a benzene sulfonate group attached to the mth carbon in a hexad...

Abstract The linear response of a photomultiplier tube (PMT) is required property for photon counting and reconstruction the neutrino energy. linearity valid region saturation PMT were investigated using linear-alkyl-benzene (LAB)-based liquid scintillator. A correlation was observed between two different responses, with pulse-shape distortion pulse-area decrease. provides useful information es...

High-symmetry (left) and low-symmetry (e.g. that on the right) conformations of benzene-1,3,5-tricarboxamide dimers derived from glycine alkyl esters are in rapid exchange solution through amide/ester competition for binding N–H donors.

conclusions with the proper operation of wastewater the treatment plant and increasing the retention time, the removal efficiency of the detergents increased. in addition, according to the environmental standards for bod5, cod and the detergents, the results of the present study indicated that the outputs of these parameters from the sbr system were appropriate for agricultural irrigation. resu...
