Copper and arsenic have been analysed in refined beet sugar at the microgram kg-1 level by anodic stripping voltammetry (copper) and cathodic stripping voltammetry (arsenic) in the differential-pulse mode (DPASV and DPCSV) at a hanging mercury drop electrode (HMDE). DPCSV measurements of arsenic are based on its accumulation onto the HMDE as an intermetallic Cu-As compound followed by the reduc...

lead forms the complexes with xylenol orange in the basic solution. an adsorptivedifferential pulse stripping method for the determination of lead is proposed. the procedureinvolves an adsorptive accumulation of lead on a hanging mercury drop electrode (hmde) inthe presence of xylenol orange, followed by reduction of adsorbed lead by voltammetric scanusing differential pulse modulation. the opt...

I By adding an impaction plate in a graphite furnace it is possible to separate and collect 6μm particles which are found in cigarette smoke. This allows for the quantitative detection of Cd, Cr, Pb and Mn in air in a direct fashion and quasi real time. It is important to monitor not only direct inhalation of cigarette smoke but also “second-hand” smoking by innocent by-standers. II Most Hg spi...

We study the eikonal model for the nuclear-induced breakup of Borromean nuclei, using 11Li and 6He as examples. The full eikonal model is difficult to realize because of six-dimensional integrals, but a number of simplifying approximations are found to be accurate. The integrated diffractive and onenucleon stripping cross sections are rather insensitive to the neutron–neutron correlation, but t...

OBJECTIVE This case study was conducted to evaluate the treatment and management of a patient presenting with medial elbow pain diagnosed as medial epicondylosis. CASE A 35 year old male presented with medial elbow pain of 4-6 weeks duration that worsened after playing squash. TREATMENT A COURSE OF FASCIAL STRIPPING TECHNIQUES WAS INITIATED, INCLUDING: cross friction massage, instrument ass...

Today, a consensus that DNA working as a molecular wire shows promise in nanoscale electronics is reached. Considering that the "ON-OFF" switch is the basis of a logic circuit, the switch of DNA-mediated charge transport (DNA CT) should be conquered. Here, on the basis of chemical or electrochemical deposition and stripping of DNA-templated copper nanoclusters (CuNCs), we develop an "ON-OFF" na...

This paper focuses on current developments and future prospects in developing electrochemical stripping methodologies for on-site monitoring of trace metals. Particular attention is given to the replacement of bulky electrodes and cumbersome cells with self-contained test strips. Coupled with a greatly simplified stripping operation and the introduction of high-quality , user-friendly, compact ...

Detailed 3-D numerical simulations of an elliptical galaxy orbiting in a gas-rich cluster of galaxies indicate that gas dynamic stripping is less efficient than the results from previous, simpler calculations (Takeda et al. 1984; Gaetz et al. 1987) implied. This result is consistent with X-ray data for cluster elliptical galaxies. Hydrodynamic torques and direct accretion of orbital angular mom...

Deep 21-cm H i line observations of the Virgo cluster spiral galaxy NGC 4569 have been obtained with the VLA in its D configuration and with the Effelsberg 100-m telescope. A low surface density arm was discovered in the west of the galaxy, whose velocity field is distinct from that of the overall disk rotation. The observed gas distribution, velocity field, and velocity dispersion are compared...

The skin protects the human body by providing barrier function. Interleukin (IL)-33 is a tissue-derived cytokine, mainly expressed epithelial and endothelial cells, known to activate Th2 lymphocytes, mast ILC2, eosinophils. We aimed study role of IL-33 in Wild-type (WT), knockout (IL-33KO) mice were tape stripped, trans-epidermal water loss (TEWL) was monitored. Skin samples corrected, hematoxy...
