in this work, poly (o-anisidine) (poa) was prepared by consecutive potential cycling in an acidic monomer solution at the surface of carbon paste electrode (cpe). nickel ions were dispersed into the polymer by immersing the electrode in niso4 solution. the prepared ni/poa/cpe was characterized by scanning electron microscopy, energy dispersive x-ray spectroscopy, atomic force microscopy (afm) a...

Family Planning Perspectives ceding injection—even if she receives her next injection only a few days late. She must then “restart” the method, even though her last DMPA injection may still be protecting her from pregnancy. Moreover, if all contraceptive users were categorized according to what they report to be their current method, and according to their adherence to that method’s regimen (an...

The 2002 National Survey of Family Growth reported that 5.3% of all US women aged 15 through 44 currently using contraception used DMPA.1 Among contraceptors, 13.9% of those aged 15 to 19 and 10.1% of those aged 20 to 24 currently used DMPA compared with 1.6% of those aged 40 to 44.1 Decreasing rates of adolescent pregnancy between 1995 and 2002 are considered to be due in part to increased use...

This paper reports the isolation of phenoloxidase-negative mutants of the white-rot fungus Phanerochaete chrysosporium and the results of a survey of idiophasic functions among these mutants. The mutant strains were isolated from a medium containing o-anisidine after gamma irradiation of wild-type spores and fell into four classes, divided by the manner in which they mineralized 14C-lignin whea...

Wheat straw is the major crop residue in European countries which makes it the most promising material for bioconversion into biofuels. However, cellulose and hemicellulose are protected with lignin, so delignification is an inevitable phase in lignocellulose processing. The organisms predominantly responsible for its degradation are white-rot fungi and among them Trametes species represent pro...

ABSTRACT: The objective of this study was to determine the response to increments of 2 sources of dietary fat on lactating sow and progeny performance during high ambient temperatures. Data were collected from 391 sows (PIC Camborough) from June to September in a 2,600-sow commercial unit in Oklahoma. Sows were randomly assigned to a 2 × 3 factorial arrangement of treatments and a control diet....

Background and Objectives: Stability of the products made from pistachios depends on stability of the oil. Oxidized oil includes unpleasant taste and thus its quality and shelf-life decreases. The aim of this study was to assess pistachio oil oxidation stability alone and in combination with Carotino oil and monoglyceride emulsifier using method of accelerated temperature (60 °C).  Materials &...
