the aim of this study was to measure the alterations in serum zinc (zn) copper (cu) and iron (fe) concentrations in patients with acute and chronic cutaneous leishmaniasis. serum zinc and copper were measured by flameless atomic absorption spectrophotometer and serum iron concentration was measured by the ferrozine method with commercial kits and assay was carried out by using an automatic anal...

background & aim: in some studies, changes in trace elements of abuse of addictive substances have been mentioned. due to the effects of trace elements on the immune system and their effects on susceptibility to infectious agents, the purpose of this study was to investigate the effect(s) of morphine dependency on the concentration of trace elements (copper, zinc and manganese) levels in serum ...

synthetic envelopes have been found to be highly effective filters for numerous applications and are currently replacing gravel envelopes. the growth of petrochemical and textile industries in iran offers the possibility of manufacturing these products domestically. the objective of this study was to assess the mineral clogging potential of two non-woven synthetic envelopes (pre-wrapped loose m...

CO isotopes are able to probe the different components in protostellar clouds. These components, core, envelope and outflow have distinct physical conditions and sometimes more than one component contributes to the observed line profile. In this study we determine how CO isotope abundances are altered by the physical conditions in the different components. We use a 3D molecular line transport c...

We describe the classical Schwinger model as a study of the pro-jective modules over the algebra of complex-valued functions on the sphere. On these modules, classified by π 2 (S 2), we construct her-mitian connections with values in the universal differential envelope which leads us to the Schwinger model on the sphere. The Connes-Lott program is then applied using the Hilbert space of complex...

Dunaliella salina cells rapidly diluted from their normal 1.71 M NaCl-containing growth medium into medium containing 0.86 M NaCl swelled within 2--4 min to an average volume 1.76 X larger and a surface area 1.53 X larger than found in control cells. Morphometric analysis of thin section electron micrographs revealed that certain organelles, including the chloroplast, nucleus, and some types of...

We present high spectral resolution mid-IR observations of SiS towards the C-rich AGB star IRC+10216 carried out with the Texas Echelon-cross-Echelle Spectrograph mounted on the NASA Infrared Telescope Facility. We have identified 204 ro-vibrational lines of 28Si32S, 26 of 29Si32S, 20 of 28Si34S, and 15 of 30Si32S in the frequency range 720 - 790 cm-1. These lines belong to bands v = 1 - 0, 2 -...

ABSTRACT We present Hubble Space Telescope imaging of a pre-explosion counterpart to SN 2019yvr obtained 2.6 yr before its explosion as type Ib supernova (SN Ib). Aligning post-explosion Gemini-S/GSAOI image, we demonstrate that there is single source consistent with being the progenitor system, second candidate after iPTF13bvn. also analysed Spitzer/Infrared Array Camera (IRAC) imaging, but do...

Abstract Tracking electron motion in molecules is the key to understanding and controlling chemical transformations. Contemporary techniques attosecond science are able generate trace consequences of this real time, but not space. Scanning tunnelling microscopy, on other hand, can locally probe valence density molecules, cannot alone provide dynamical information at ultrafast timescale. Here we...
