f(x) = (sec 12x)(sec 12x+ tan 12x). A3 The limit is 0; we will show this by checking that dn = 0 for all n ≥ 3. Starting from the given matrix, add the third column to the first column; this does not change the determinant. However, thanks to the identity cosx+ cos y = 2 cos x+y 2 cos x−y 2 , the resulting matrix has the form  2 cos 2 cos 1 cos 2 · · · 2 cos(n+ 2) cos 1 cos(n+ 2) · · · 2 cos...

High molecular weight nanocrystalline chitosan (HMWNC)with Mw of 350 kDa and 66.92% DDA was prepared by alkaline N-deacetylation chitin that abundantly obtained after demineralization deproteinization pulverized crab shells, commercially available oligosaccharide (COS) with average Mw< 3000 Da 87% encapsulated HMWNC. The encapsulation COS as a pharmaceutical ingredient into HMWC hypothesized...

BACKGROUND There are numerous challenges in including patients in a core outcome set (COS) study, these can vary depending on the patient group. This study describes current efforts to include patients in the development of COS, with the aim of identifying areas for further improvement and study. METHODS Using the COMET database, corresponding authors of COS projects registered or published f...

Baldocchi, D.D., Verma, S.B. and Rosenberg, N.J., 1981. Seasonal and diurnal variation in the CO 2 flux and COs---water flux ratio of alfalfa. Agric. Meteorol., 23: 231--244. The seasonal and diurnal variation of CO2 flux (F c ) and COs--water flux ratio (CWFR) of alfalfa were studied using micrometeorological techniques during the summer of 1978 at a location in the east central Great Plains. ...

BACKGROUND The use of core outcome sets (COS) ensures that researchers measure and report those outcomes that are most likely to be relevant to users of their research. Several hundred COS projects have been systematically identified to date, but there has been no formal quality assessment of these studies. The Core Outcome Set-STAndards for Development (COS-STAD) project aimed to identify mini...
