Abstract Orange peels (OPs) were valorized in a lab-scale biorefinery loop for the recovery of limonene and subsequent production volatile fatty acids (VFAs) activated carbon (AC). Solid/liquid extraction was optimized using n -hexane at 85 °C with an OPs-to-solvent ratio 2:1, allowing yield 1.20% w/w. Then, post-extraction OPs used both VFAs AC. For VFA production, hydraulic retention time (HR...

This study reports about the construction of a bidimensional measure of optimism and pessimism (defined as positive and negative outcome expectancies), called the Japanese Optimism and Pessimism Scale (J-OPS), and examines its reliability and validity. The participants were college students. The results revealed the following: (a) the J-OPS had sufficient reliability and validity, (b) optimism ...

BACKGROUND The effects of exposure time (20 versus 45 s) to a high concentration of cryoprotectant (7.0 mol/l ethylene glycol with 0.5 mol/l sucrose) and freezing rates (1200-10 300 degrees C/min) during rapid freezing of mouse pronuclear stage embryos on survival and development to blastocysts were investigated. Different freezing rates were achieved by directly plunging the straws (rapid free...

Oxyphytosterols (OPS) were fed to hamsters, at different concentrations, in order to observe their eventual incorporation into plasma, aorta, liver, kidneys and heart. The animals receiving the very high level (2500 ppm) presented 7beta-hydroxycampesterol, beta-epoxycampesterol, campestanetriol, 7-ketocampesterol, 7beta-hydroxysitosterol, beta-epoxysitosterol, sitostanetriol and 7-ketositostero...

Background: International policy is increasingly committed to placing interdisciplinary team-working at the centre of health and social care integration across lifespan. The National Clinical Programme for Older People in Ireland has a critical role design implementation Person’s Service Model, which aims shift delivery away from acute hospitals towards community-bas...

There is no clear single factor to date that explains colony loss in bees, but one factor proposed is the wide-spread application of agrochemicals. Concentrations of 14 organophosphorous insecticides (OPs) in honey bees (Apis mellifera) and hive matrices (honey and pollen) were measured to assess their hazard to honey bees. Samples were collected during spring and summer of 2013, from 5 provinc...

BACKGROUND To enable occupational physicians (OPs) to make use of scientific information in the decision-making process, evidence-based occupational health practice is stimulated. AIMS To study the questions which arise in daily practice of OPs, and to evaluate the possible contribution of evidence-based medicine (EBM) strategies to answer these questions. METHODS Observation of 20 OPs duri...

The antitumor activity of the polysaccharide fraction (OPS) obtained by the acid hydrolysis of Klebsiella O3 lipopolysaccharide (KO3 LPS) isolated from the culture supernatant of the decapsulated mutant strain LEN-1 (03: K1-) against both allogeneic tumor and syngeneic tumor systems in mice was compared with that of KO3 LPS. OPS prolonged the life span of MM2-bearing C3H/He mice by intraperiton...

OBJECTIVES The competencies required of occupational physicians (OPs) and occupational health nurses (OHNs) separately have been studied in various countries but little research has made direct comparisons between these two key occupational health (OH) professional groups. The aim of this study was to compare current competency priorities between UK OPs and OHNs. METHODS A modified Delphi stu...

The levels, distribution, and possible sources of 12 organophosphorus flame retardants and plasticizers, some of which are reported to be toxic to aquatic organisms, were investigated in samples of influents, effluents, and sludge from 11 Swedish sewage treatment plants (STPs). The organophosphorus compounds (OPs) studied were poorly removed from the wastewater; especially the chlorinated OPs t...
