A bstractWe study the LHC phenomenology of flavor changing Yukawa couplings between the top quark, the Higgs boson, and either an up or charm quark. Such tuh or tch couplings arise for instance in models in which the Higgs sector is extended by the existence of additional Higgs bosons or by higher dimensional operators. We emphasize the importance of anomalous single top plus Higgs production in these scenarios, in addition to the more widely studied t → hj decays. By recasting existing CMS searches in multilepton and diphoton plus lepton final states, we show that bounds on ℬ$$ \mathrm{\mathcal{B}} $$(t → hu) are improved by a factor of 1.5 when single top plus Higgs production is accounted for. We also recast the CMS search for vector boson plus Higgs production into new, competitive constraints on tuh and tch couplings, setting the limits of ℬ$$ \mathrm{\mathcal{B}} $$(t → hu) < 0.7% and ℬ$$ \mathrm{\mathcal{B}} $$(t → hc) < 1.2%.We then investigate the sensitivity of future searches in the multilepton channel and in the fully hadronic channel. In multilepton searches, studying the lepton rapidity distributions and charge assignments can be used to discriminate between tuh couplings, for which anomalous single top production is relevant, and tch couplings, for which it is suppressed by the parton distribution function of the charm quark. An analysis of fully hadronic t + h production and t → hj decay can be competitive with the multilepton search at 100 fb−1 of 13 TeV data if jet substructure techniques are employed to reconstruct boosted top quarks and Higgs bosons. To show this we develop a modified version of the HEPTopTagger algorithm, optimized for tagging t → hj decays. Our sensitivity estimates on ℬ$$ \mathrm{\mathcal{B}} $$(t → hu) (ℬ$$ \mathrm{\mathcal{B}} $$(t → hc)) at 100 fb−1 of 13 TeV data for multilepton searches, vector boson plus Higgs search and fully hadronic search are 0.22% (0.33%), 0.15% (0.19%) and 0.36% (0.48%), respectively.

Este trabalho objetiva, atraves de pesquisa bibliografica, analisar o uso e as consequencias do alcool e tabaco durante a gestacao. Foram utilizados artigos cientificos publicados entre 2005 e 2011. O alcool e absorvido pela corrente sanguinea, afetando todos os tecidos do corpo. Estudos apontam que 30 ml/dia pode causar o abortamento espontâneo, alteracoes funcionais, anomalias do SNC, deficit de crescimento, prematuridade, deficiencias cardiacas, SAF (sindrome alcoolica fetal), entre outras. O tabaco possui mais de 4.000 substâncias em sua composicao, muitas ainda nao conhecidas, mas prejudiciais ao feto. Estudos apontam que apenas 20% das mulheres gestantes param de fumar durante a gestacao, as primigestas sao as que abandonam o vicio. Embora muitas orientacoes sejam feitas durante as consultas medicas no pre-natal, e de competencia do enfermeiro, atraves de palestras, grupos de gestantes e ate mesmo nas consultas de pre-natal, orientar sobre os maleficios do uso dessas substâncias.

The guidance of nursing the pregnant women that make use of alcohol and tobacco Abstract: The goal of this paper is, through bibliographic research; analyze the use and consequences of alcohol and tobacco during pregnancy. For this study, we used scientific articles published between 2005 and 2011. The alcohol absorbed into the bloodstream, affects all body tissues. Studies show that 30 ml/day can cause spontaneous abortion, functional alterations, facial abnormalities, CNS anomalies, impaired growth, prematurity, heart failure, AFS, among others. The tobacco has more than 4,000 substances in their composition, many not yet known, but harmful to the fetus. Studies show that only 20% of pregnant women stop smoking during pregnancy, prim gravidae are the ones who abandon the habit. Although many guidelines are made during the visits of prenatal care, it is the competence of nurses, through lectures, pregnancy groups and even in prenatal consultations, guidance about the dangers of these substances.

La orientacion de enfermeria las mujeres embarazadas que hacen uso del alcohol y tabaco Resumen: Este articulo pretende, a traves de la literatura, analizar el uso y consecuencias del alcohol y el tabaco durante el embarazo. Se utilizo articulos cientificos publicados entre 2005 y 2011. El alcohol se absorbe en el torrente sanguineo, afectando todos los tejidos del cuerpo. Los estudios muestran que 30 ml / dia puede causar aborto espontaneo, los cambios funcionales, alteraciones del SNC, retraso del crecimiento, prematuridad, insuficiencia cardiaca, SAF, entre otros. El tabaco tiene mas de 4.000 sustancias en su composicion, muchos aun no se conoce, pero perjudicial para el feto. Los estudios muestran que solo el 20% de las mujeres embarazadas a dejar de fumar durante el embarazo, primigravidas estan abandonando el habito. Aunque las directrices muchos se hacen durante las visitas de atencion prenatal es la competencia de las enfermeras, a traves de conferencias, grupos de orientacion de las mujeres embarazadas e incluso en las consultas previas al parto, sobre los peligros de estas sustancias.

Abstract Nickel ferrite nanoparticles were annealed in order to find dependence of electric/magnetic properties on crystallite size. The following correlations of crystallite size with physical parameters were found: (a) lattice parameter decreases with the increase in size and it reaches value for bulk counterpart approximately for crystallites bigger than 7 nm, (b) ac electrical resistivity at room temperature increases with the increase in crystallite size, (c) for crystallites of ~7 nm or smaller electrical resistivity have maximum value at 50 °C, (d) the real part of permittivity at selected frequency generally decreases with the increase in crystallite size and (e) magnetization increases with the increase in crystallite size. Deviation of stoichiometry, cation polyvalence, and cation redistribution with annealing are the main factors that influence physical properties of Nickel ferrite nanoparticles.

Background: Higher cardiovascular (CV) morbidity and mortality in depressed patient has demonstrated repeatedly. Aim: Determine the degree of occurrence of hypertension, metabolic syndrome (MetS) and depression in the pit miners and the impact of the six-month holistic treatment of all CV risk factors and depression in the overall CV risk in miners with hypertension, MetS and depression. Methods: From 492 pit miners was taken smoking status, measured blood pressure, waist circumference and body mass index. Analysis was done using the concentration of sugar in blood, triglycerides, total cholesterol, HDL, LDL cholesterol and determined total CV risk. All respondents filled self-assessment Beck's depression scale. Prevalence MetS hypertension and depression were determined. Group of 67 patients with joint hypertension, MetS and depression that is treated six months with psychotropic and somatotropin medication, was singled out. After six months, the effect of therapy on the risk factors and total CV was assessed. Results: Among 492 miners 67 (13,61%) of them had hypertension, MetS and depression. After six months treatment, it showed statistically significant reduction in blood pressure (p=0,0001), waist circumference (p=0,0001) ,total (p=0,002), HDL (p=0,007) and LDL cholesterol (p=0,003), smoking (p=0,002), Beck's scale results (p=0,007) and reduction in total CV risk. Conclusion: After six month of combine therapy in respondents has led to reduced CV risk and level of all factors, except BMI and triglycerides.
