Catalytic activity and visible spectroscopy of [Rh(norbornadiene)Cl]2/p-RC6H4)3P system in methanol
(1984)
The catalytic hydrogenation of hex-1-ene in methanolic solution with [Rh(norbornadiene)Cl]2/(p-RC6H4)3 P (R=H, Me or OMe) systems preparedin situ has been measured. The catalytic activity shows a dependence on the ageing ...
Fleur-de-lis Abdominoplasty and Neo-umbilicus
(Elsevier B.V., 2019-01-01)
Body contouring for patients with massive weight loss may demand not only lifting but also some extent of central body tightening to achieve complete tissue readjustment. Although the fleur-de-lis procedure usually achieves ...
Expression of estrus improves fertility and decreases pregnancy losses in lactating dairy cows that receive artificial insemination or embryo transfer
(2016-03-01)
The objective was to evaluate if expression of estrus by dairy cattle altered fertility in timed artificial insemination (AI; n = 5,430) or timed embryo transfer (ET; n = 2,003) programs that used estradiol and progesterone ...
Resolving asymmetries along the pulsation cycle of the Mira star X Hydrae
(EDP Sciences, 2015)
Context. The mass-loss process in Mira stars probably occurs in an asymmetric way where dust can form in inhomogeneous circumstellar
molecular clumps. Following asymmetries along the pulsation cycle can give us clues about ...
Broadband NIR emission in novel sol-gel Er3+-doped SiO 2-Nb2O5 glass ceramic planar waveguides for photonic applications
(2013-01-01)
This paper reports on the sol-gel preparation and structural and optical characterization of new Er3+-doped SiO2-Nb 2O5 nanocomposite planar waveguides. Erbium-doped (100-x)SiO2-xNb2O5 waveguides were deposited on ...
Periodontal condition in patients with rheumatoid arthritis
(2008-01-01)
The purpose of this clinical study was to investigate if periodontal disease and rheumatoid arthritis (RA) are associated. The study included 39 RA patients (test group) and 22 age- and gender-matched healthy individuals ...
Diagnóstico técnico e financeiro das perdas hídricas do sistema de abastecimento de água de Ponta Negra, Natal/RN
(Universidade Federal do Rio Grande do NorteBrasilUFRNCURSO DE ENGENHARIA AMBIENTALCENTRO DE TECNOLOGIA, 2021-09-17)
In every Water Supply System there are water losses, which can be classified as real
losses, when there is a lost volume of water, that is, physical loss of the resource, which
occur at the collection, adduction or ...
A comparative-study between visible-light-activated and autopolymerizing sealants in relation to retention
(Amer Soc Dentistry Child, 1991-07-01)
Two hundred twenty-nine first permanent molar occlusal surfaces were treated with sealants, from a group of sixty-one children. When the three sealants were analyzed at the end of the six-, twelve-, eighteen-, and ...
