The aim of this study is to assess vitamin D levels in eclampsia, preeclampsia and healthy pregnant women and the role of vitamin D deficiency in the etiology of preeclampsia (PE). Forty healthy pregnant women, 83 preeclamptic and 32 eclamptic pregnant women were included. Maternal and infant medical records were reviewed. Blood samples were obtained from all groups. Demographics and serum vita...
this thesis basically deals with the well-known notion of the bear-invariant of groups, which is the generalization of the schur multiplier of groups. in chapter two, section 2.1, we present an explicit formula for the bear-invariant of a direct product of cyclic groups with respect to nc, c>1. also in section 2.2, we caculate the baer-invatiant of a nilpotent product of cyclic groups wuth resp...
We describe procedures for the measurement of the differential-cross-section moments of the velocity distribution of the state-selected products of photoinitiated bimolecular reactions using resonance-enhanced multiphoton ionization REMPI detection and some form of laboratory velocity selection such as time-of-flight mass spectrometry. The relative ionization probability of a single product mol...
Low maternal vitamin D levels have been associated with adverse pregnancy outcome. A recent study has suggested that low maternal vitamin D levels at the time of delivery are also associated with an almost fourfold increase in caesarean section risk. The aim of the present study was to investigate whether there is a difference in maternal serum 25-hydroxyvitamin D (25(OH)D) levels at 11–13 week...
The time and the spatial correlations play important roles in non-equilibrium statistical physics [1-16]. The behaviors of the correlation functions in ordinary fluids are well understood. It is known that there exist long-time tails in the time correlation functions in fluids at equilibrium [1, 2, 3, 4]. In addition, long-range correlations exist in the spatial correlation functions in non-equ...
Using data collected with the CLEO detector operating at the CESR e+e− collider at √ s = 3.974.26GeV, we investigate 15 charmonium decay modes of the ψ(4040), ψ(4160), and Y (4260) resonances. We confirm, at 11σ significance, the BaBar Y (4260)→ π+π−J/ψ discovery, make the first observation of Y (4260) → π0π0J/ψ (5.1σ), and find the first evidence for Y (4260) → K+K−J/ψ (3.7σ). We measure e+e− ...
Two new records of Dendrobium, D. daklakense, and metrium, are reported for the flora Laos first time. Photographs, information on habitat ecology, vernacular names additional notes each species given based collections from Dak Cheung Plateau, Sekong Province (D. daklakense), Phou Khao Khouay National Park, Vientiane metrium). An updated checklist with classification section Dendrobium in is al...
