Introduction: It is generally accepted that groundwater is one of the most vital sources of water for drinking use in cities and rural areas. The water drawn from these sources should be sanitary, have low soluble substances, and be free of any pathogens and microorganisms. Materials and Methods: In this study, 90 wells were sampled with proper dispersion over the study area to achieve suitabl...

The South China Sea (SCS) is the largest marginal sea of the western Pacific Ocean, yet little is known about archaeal distributions and TEX₈₆-based temperatures in this unique oceanic setting. Here we report findings of abundances in both core lipids (CL) and intact polar lipids (IPL) of Archaea from surface water (CL only) and core-top sediments from different regions of the SCS. TEX₈₆-derive...

The affinities of typical and atypical benzodiazepines (BZs) for 3H-flunitrazepam (FLU) and 3H-Ro 5-4864, "peripheral" BZ, binding sites in the central nervous system (CNS) were compared. Each dissociation constant (Kd) value of the 3H-FLU binding sites in the cerebellum, cortex, hippocampus and spinal cord showed the similar results, although the binding maximum (Bmax) for the cortex and cereb...

The combination of ultrasonic nebulization with membrane desolvation (USN-MD) is utilized to determine active pharmaceutical ingredients (API) by heteroatom inductively coupled mass spectroscopy (ICP-MS) detection. Ultrasonic nebulization provides efficient sampling while use of the membrane desolvator acts to reduce solvent-based interferences. This approach reduces interferences sufficiently ...

Carlsson, Ola, and Bengt Rippe. Peritoneal lymphatic absorption and solute exchange during zymosan-induced peritonitis in the rat. Am. J. Physiol. 277 (Heart Circ. Physiol. 46): H1107–H1112, 1999.—Lymph flow is elevated in most inflammatory conditions. However, a few previous studies have indicated that peritoneal lymph flow may actually fall during acute peritonitis. This study was performed t...

Optical emission ~OE! actinometry has been used to measure the absolute densities of Cl2, Cl, Cl , and Ar in a high-density inductively coupled ~ICP! Cl2 –Ar plasma at 18 mTorr as a function of the 13.56 MHz radio frequency ~rf! power and Ar fraction. The fractional dissociation of Cl2 to Cl increases with rf power, with the dissociated fraction increasing from 78% to 96% at 600 W ~10.6 W cm! a...

This study investigates the δ O of pore 18 waters from Sites 1003-1007 collected during Leg 166 of the Ocean Drilling Program which drilled sites along the western margin of Great Bahama Bank. These data generally show a positive correlation between δ O and the 18 concentration of chloride with the exception of Site 1006 which exhibits non-linear behavior with respect to chloride. However, the ...

An essential aspect of a generally covariant system is the invariance of its action under reparametrizations; this means that the label that parametrizes the trajectories of the system is not the time but a physically irrelevant parameter. As a consequence, the system is constrained to remain on the hypersurface of the phase space where the Hamiltonian is null. In fact, since the “evolution” ge...

remind the inhabitants of this country that the water in which they enjoy so frequently the refreshing effects of a "plunge wash" is drawn from polluted sources; stores of water collected from surface drainage?water that has passed over soil laden with dead animal and vegetable products, and hence loaded with millions of enemies to human life. It is palpably more poisonous during, and after, th...

This study presents morphological and elemental characteristics of aerosols for the duration January-June, 2021, using Scanning Electron Microscope coupled with Energy Dispersive X-Ray (SEM–EDX). The results revealed that there were numerous spherical particles (Dα ≤ 2.5 µm) but did not produced expected EDX-spectra constituents. Limited deposited observed which showed definite constitutions. s...
