some new water-soluble schiff base complexes of na2[m(5-so3-1,2-salophen)].nh2o; (5-so3-1,2-salophen = n,n’-bis(5-sulphosalicyliden)-1,2-phenylendiamine); na2[m(5-so3-2,3-salpyr)(h2o)n].2h2o; (5-so3-2,3-salpyr = n,n’-bis(5-sulphosalicyliden)-2,3-diaminopyridine); and na2[m(5-so3-3,4-salbenz)(h2o)n].nh2o; (5-so3-3,4-salbenz = n,n’-bis(5-sulphosalicyliden)-3,4-diaminobenzophenon); where m = cu, n...
The title compound, C(51)H(78)INO(12), contains a 29-membered ring incorporating amide, lactone and ester groups. It contains a total of 15 stereogenic centres. In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonds, forming C(8) chains propagating in [100]. A weak intra-molecular O-H⋯O inter-action also occurs.
We study representations of integers n in binary expansions using the digits 0,±1. We analyze the average number of such representations of minimal “weight” (= number of non-zero digits). The asymptotic main term of this average involves a periodically oscillating function, which is analyzed in some detail. The main tool is the construction of a measure on [−1, 1], which encodes the number of r...
endpoint was the change from baseline to week 12 in trough sitting systolic BP. Mean baseline systolic BP was approx imately 165 mm Hg. (Stage 2 hypertension is normally defined as a reading above 160/100 mm Hg.) At 12 weeks, clinical systolic BP was reduced by 42.5 and 44 mm Hg in the azilsartan/CLD 40/25-mg and 80/25-mg groups, respectively, compared with 37.1 mm Hg in the olmesartan/HCTZ 40/...
BACKGROUND Ensuring adequate vitamin D status in older adults may reduce the risk of osteoporosis. The serum 25-hydroxyvitamin D [25(OH)D] concentration is the recommended biomarker of vitamin D status, but the optimal serum 25(OH)D concentration for bone health in postmenopausal women remains unclear. OBJECTIVE The aim of this study was to apply the highly sensitive (41)Ca skeletal labeling ...
The physiological nature of photoinduced germination of Onoclea sensibilis L. spores was investigated by temporarily applying a range of temperatures, particularly 40 C, before and after short light treatment. Controls were germinated at 25 C.The preinduction phase, during which photosensitivity is maximally developed in the dark, is sensitive to temperature. Treatment at 40 C for 8 or more hou...
introduction acetic acid bacteria are large group of obligate aerobic gram negative bacteria with the ability to oxidize ethanol to acetic acid (1). they are widely distributed in natural habitats and classified in family acetobacteraceae. members of this family are useful in industrial production of vinegar(2). acetic acid bacteria (aab) can use substrates as glucose, ethanol, lactate or glyc...
[1] The reliability of the global reanalyses in the polar regions is investigated. The overview stems from an April 2006 Scientific Committee on Antarctic Research (SCAR) workshop on the performance of global reanalyses in high latitudes held at the British Antarctic Survey. Overall, the skill is much higher in the Arctic than the Antarctic, where the reanalyses are only reliable in the summer ...
