deal effectively with the increased density of the pork industry in some areas and the increased public concerns regarding nutrient excretion and odour emissions. Successful management of nitrogen and phosphorus is key for sustainable pork production to address these public concerns. For example, nitrogen excretion in the form of ammonia is a concern because of its impact on the work environmen...

Some facts about sines and cosines: • cos(A+B) = cos(A) cos(B)− sin(A) sin(B) • sin(A+B) = sin(A) cos(B) + cos(A) sin(B) • Cosine is an even function: cos(−θ) = cos(θ) • Sine is an odd function: sin(−θ) = − sin(θ) • cos(ωt− π/2) = sin(ωt) • R cos(ωt + φ) = R sin(φ) cos(ωt) + R cos(φ) sin(ωt), and any wave form can be written as a linear combination of sines and cosines. Similarly, A sin(ωt) +B ...

BACKGROUND Core outcome sets (COS) can enhance the relevance of research by ensuring that outcomes of importance to health service users and other people making choices about health care in a particular topic area are measured routinely. Over 200 COS to date have been developed, but the clarity of these reports is suboptimal. COS studies will not achieve their goal if reports of COS are not com...

5 . (b) Applying the product rule, we have ((1 + 4x)e−4x)′ = (1 + 4x)′e−4x + (1 + 4x)(e−4x)′ = 4e−4x + (1 + 4x)e−4x(−4x)′ = 4e−4x + (1 + 4x)e−4x(−4) = 4e−4x − 4e−4x − 16xe−4x = −16xe−4x. (c) [(sec(x) + tan(x))3]′ = 3(sec(x) + tan(x))(sec(x) + tan(x))′ = 3(sec(x) + tan(x))(sec(x) tan(x) + sec(x)) = 3(sec(x) + tan(x)) · sec(x) · (sec(x) + sec(x)) = 3 sec(x)(sec(x) + tan(x)). (d)(x cos(x)− 6x sin(...

To enhance the mechanical and antibacterial properties of silver nanoparticle impregnated cellulosic fibers, carboxy-cellulose nanocrystals(CCNs) were grafted with chitooligosaccharide(COS), which was used as a stabilizer for nanoparticles (AgNPs). Nanofibrous membranes reinforced fibers(CCN-COS-AgNP) prepared via electrospinning using polyvinyl alcohol(PVA) matrix. The effects CCN-COS-AgNP con...

Abstract In this study, a multifunction polymeric adhesion promoter and anti-aging compound based on the triethanolamine salt of acrylamide acrylic acid copolymer (COS) was prepared characterized using Fourier-transform infrared spectroscopy (FTIR). The impact different COS contents tensile, adhesion, thermal properties NBR composite NBR/PET sandwich evaluated. composites containing displayed g...

Chitosan and its oligosaccharides exhibit numerous biochemical characteristics, which includes immune enhancing, antimicrobial anti-viral properties. products have drawn much attention of both food pharmaceutical industry due to their peculiar physiochemical characteristics effectiveness in cancer therapies. Current study describes the different physiological chemical properties along with usef...

BACKGROUND There are few studies on pediatric HIV-HBV coinfection, so evidences about relationships between the two viruses are scarce. OBJECTIVES influence of HBV infection on virological and immunological response to antiretroviral therapy (ART) in antiretroviral-naïve horizontally HIV-HBV coinfected subjects during early childhood. MATERIAL AND METHODS observational study on 826 HIV+ sub...

objective: β-thalassemia is caused by absence or reduction of β-globin chain synthesis. one of the effective therapeutic methods for this disease can be gene therapy by viral vectors. the capacity of lentiviral vectors is approximately 8 kb, we designed a 6 kb construct containing mini lcr and β-globin gene instead of lcr region. the aim of this study is to make a recombinant lentiviruses conta...

Carbonyl sulfide (COS) and dimethyl sulfide (DMS) fluxes from an urban Cynodon dactylon lawn and adjacent bare soil were measured during April-July 2005 in Guangzhou, China. Both the lawn and bare soil acted as sinks for COS and sources for DMS. The mean fluxes of COS and DMS in the lawn (-19.27 and 18.16 pmol/(m2 sec), respectively) were significantly higher than those in the bare soil (-9.89 ...
