MANEJO FLORESTAL EM LlNHARES - CRESCIMENTO EM FUNÇÃO DE DIFERENTES NÍVEIS DE INTERVENÇÃO

Com o objetivo de conhecer o efeito de diferentes intensidades de exploração em uma área de floresta de tabuleiro da Mata Atlântica, foi instalado um ensaio de manejo florestal sustentado na Reserva Florestal de Unhares, pertencente à Companhia Vale do Rio Doce - CVRD, localizada no município de Unhares (ES). O delineamento estatístico do ensaio foi o de blocos ao acaso, com cinco repetições e nove tratamentos. O ensaio foi instalado em 1980 e as avaliações foram efetuadas através dos dados coletados nos inventários inicial (1980), pós-exploratório (1980) e contínuos (1983, 1987 e 1990)

PERFIL NUTRICIONAL DE HIPERTENSOS EM ACOMPANHAMENTO EM UNIDADES BÁSICAS DE SAÚDE DO MUNICÍPIO DE SÃO LUÍS – MA

A Hipertensão Arterial (HA) é considerada um problema de saúde pública, muitas vezes assintomática e de difícil controle, que pode levar a seqüelas irreversíveis.  O objetivo deste estudo foi avaliar o estado nutricional e o consumo alimentar de pacientes hipertensos. Realizou-se um estudo transversal, com pacientes hipertensos cadastrados no programa HiperDia (MS), em acompanhamento em duas Unidades Básicas de Saúde, em São Luis – MA, no período de fevereiro de 2010 a janeiro de 2011. Foram analisados dados socioeconômicos, demográfcos, estilo de vida, antropométricos e dietéticos. Para avaliar o estado nutricional foram utilizados o Índice de Massa Corpórea (IMC) e a Circunferência da Cintura (CC), segundo as recomendações propostas pela Organização Mundial de Saúde (OMS). Para avaliar o consumo energético e de nutrientes foi utilizado o método do registro alimentar de três dias, transformados posteriormente em recordatório alimentar de 24 horas (R24h). Foram avaliados 184 pacientes, com média de idade de 60,8 ± 12,9 anos, sendo a maioria do sexo feminino (76,6%), de cor não branca (85,9%), com menos de oito anos de escolaridade (75%) e com renda familiar inferior a quatro salários mínimos (53,3%). Quanto ao estilo de vida, 94,6% não fumavam, 80,4% não ingeriam bebida alcoólica e 77,6% eram sedentários. Houve prevalência de excesso de peso entre a amostra estudada (69,0%). A proporção de pacientes com obesidade abdominal foi de 54,3%, com maior frequência entre as mulheres (64,5%). Os percentuais de macronutrientes encontraram-se adequados, entretanto, o consumo energético e de fbra encontraram-se abaixo do recomendado, segundo as DRI’s (2002). Assim, houve predomínio de excesso de peso e de obesidade abdominal e o consumo energético foi inadequado para ambos os sexos.Descritores: Hipertensão Arterial; Estado Nutricional; Consumo Alimentar; Macronutrientes. Abstract:   Arterial Hypertension (AH) is considered a problem of public health, often asymptomatic and diffcult to control, which can lead to irreversible sequels. The objective of this study was to evaluate the nutritional status and dietary intake of hypertensive patients. We conducted a cross-sectional study with hypertensive patients enrolled in the program HiperDia (MS), followed in two Basic Health Units in São Luis - MA, from February 2010 to January 2011. We analyzed the data on socioeconomic, demographic, lifestyle, anthropometric and dietary factors. To evaluate the nutritional status, it was used the body mass index (BMI) and also the waist circumference (WC), according to the recommendations proposed by the World Health Organization (WHO). The energy and nutrients evaluation was evaluated by using the method of three-day food record, subsequently processed into 24-hour dietary recall (24HR). We appraised 184 patients with a mean age of 60.8 ± 12.9 years, mostly female (76.6%), non-Caucasian (85.9%), with less than eight years of schooling (75%) and household income less than four minimum salaries (53.3%). About the  lifestyle, 94.6% did not smoke, 80.4% did not drink alcohol and 77.6% were sedentary. There was a prevalence of overweight among the study sample (69.0%), no statistically signifcant difference between sexes. Regarding the distribution of body fat, the proportion of patients with abdominal obesity was 54.3%, according to waist circumference, more frequently among women (64.5%). The percentages of macronutrients found to be adequate, but, energy consumption and fber were under the recommended ones, according to DRI’s (2002). Thus, there was a predominance of overweight and abdominal obesity and caloric intake was inadequate for both sexes.Descriptors: Hypertension; Nutritional Status; Food Consumption; Macronutrients

Retardadores de crescimento no desenvolvimento e na qualidade ornamental de Zinnia elegans Jacq. 'Lilliput' envasada

As zínias têm grande potencial como plantas floríferas envasadas e representam rápida fonte de novidade para a floricultura com o auxílio de retardadores de crescimento. Avaliaram-se os efeitos de retardadores de crescimento no desenvolvimento e na produção de plantas envasadas de porte baixo, compactas e atrativas de 'Lilliput' Zinnia elegans, cultivar altamente ornamental, com sementes de baixo custo. O delineamento experimental foi em blocos casualizados, com dez tratamentos (controle e três concentrações de cada retardador: daminozide, paclobutrazol e chlormequat) e quatro repetições (dois vasos por unidade experimental, com uma planta por vaso de 0,6 L). Paclobutrazol (0,5; 0,75 e 1,0 mg i.a. por vaso) e chlormequat (1,0; 2,0 e 3,0 g L-1) foram aplicados ao substrato (40 mL por vaso), enquanto o daminozide (2,5; 3,75 e 5,0 g L-1) foi aplicado através de pulverização foliar (10 mL por vaso), no estádio de gema floral apical visível. Daminozide (2,5 e 3,75 g L-1), paclobutrazol (0,5; 0,75 e 1,0 mg i.a. por vaso) e 1,0 g L-1 de chlormequat reduziram significativamente a altura das plantas e o comprimento dos ramos laterais, sem afetar o diâmetro dos capítulos, atrasar o ciclo de produção e causar fitotoxicidade. Entretanto, as plantas não se apresentaram suficientemente baixas e compactas para atender às exigências de qualidade do mercado. Chlormequat (2,0 e 3,0 g L-1) causou fitotoxicidade e daminozide (5,0 g L-1) aumentou o ciclo de produção.Zinnias have good potential to be used as flowering, potted plants, being a quick source of novelty for the floriculture industry with the aid of growth retardants. This study evaluated the effect of growth retardants on development and production of short, compact and attractive plants of potted 'Lilliput' Zinnia elegans, a highly ornamental zinnia with low cost seeds. Trials were set up in randomized blocks, with ten treatments (control and three treatments of each retardant: daminozide, paclobutrazol and chlormequat) and four replications (two pots per experimental unit, with one plant per 0.6-L pot). Paclobutrazol (0.5, 0.75 and 1.0 mg a.i. per pot) and chlormequat (1.0, 2.0 and 3.0 g L-1) were applied as a single drench (40 mL per pot), and daminozide (2.5, 3.75 and 5.0 g L-1) as a single foliar spray to runoff (10 mL per pot), at apical flower bud stage. Daminozide (2.5 and 3.75 g L-1), paclobutrazol (0.5, 0.75 and 1.0 mg a.i. per pot) and chlormequat at 1.0 g L-1 significantly reduced plant height and side branches length, without affecting flower diameter, delaying production cycle and causing phytotoxicity symptoms. However, plants were not short and compact enough to meet market quality demand. Chlormequat (2.0 and 3.0 g L-1) caused phytotoxicity symptoms and daminozide (5.0 g L-1) delayed production cycle

Probing exotic phenomena at the interface of nuclear and particle physics with the electric dipole moments of diamagnetic atoms: A unique window to hadronic and semi-leptonic CP violation

The current status of electric dipole moments of diamagnetic atoms which involves the synergy between atomic experiments and three different theoretical areas -- particle, nuclear and atomic is reviewed. Various models of particle physics that predict CP violation, which is necessary for the existence of such electric dipole moments, are presented. These include the standard model of particle physics and various extensions of it. Effective hadron level combined charge conjugation (C) and parity (P) symmetry violating interactions are derived taking into consideration different ways in which a nucleon interacts with other nucleons as well as with electrons. Nuclear structure calculations of the CP-odd nuclear Schiff moment are discussed using the shell model and other theoretical approaches. Results of the calculations of atomic electric dipole moments due to the interaction of the nuclear Schiff moment with the electrons and the P and time-reversal (T) symmetry violating tensor-pseudotensor electron-nucleus are elucidated using different relativistic many-body theories. The principles of the measurement of the electric dipole moments of diamagnetic atoms are outlined. Upper limits for the nuclear Schiff moment and tensor-pseudotensor coupling constant are obtained combining the results of atomic experiments and relativistic many-body theories. The coefficients for the different sources of CP violation have been estimated at the elementary particle level for all the diamagnetic atoms of current experimental interest and their implications for physics beyond the standard model is discussed. Possible improvements of the current results of the measurements as well as quantum chromodynamics, nuclear and atomic calculations are suggested.Comment: 46 pages, 19 tables and 16 figures.

Search for a W' boson decaying to a bottom quark and a top quark in pp collisions at sqrt(s) = 7 TeV

Results are presented from a search for a W' boson using a dataset corresponding to 5.0 inverse femtobarns of integrated luminosity collected during 2011 by the CMS experiment at the LHC in pp collisions at sqrt(s)=7 TeV. The W' boson is modeled as a heavy W boson, but different scenarios for the couplings to fermions are considered, involving both left-handed and right-handed chiral projections of the fermions, as well as an arbitrary mixture of the two. The search is performed in the decay channel W' to t b, leading to a final state signature with a single lepton (e, mu), missing transverse energy, and jets, at least one of which is tagged as a b-jet. A W' boson that couples to fermions with the same coupling constant as the W, but to the right-handed rather than left-handed chiral projections, is excluded for masses below 1.85 TeV at the 95% confidence level. For the first time using LHC data, constraints on the W' gauge coupling for a set of left- and right-handed coupling combinations have been placed. These results represent a significant improvement over previously published limits.Comment: Submitted to Physics Letters B. Replaced with version publishe

Search for the standard model Higgs boson decaying into two photons in pp collisions at sqrt(s)=7 TeV

A search for a Higgs boson decaying into two photons is described. The analysis is performed using a dataset recorded by the CMS experiment at the LHC from pp collisions at a centre-of-mass energy of 7 TeV, which corresponds to an integrated luminosity of 4.8 inverse femtobarns. Limits are set on the cross section of the standard model Higgs boson decaying to two photons. The expected exclusion limit at 95% confidence level is between 1.4 and 2.4 times the standard model cross section in the mass range between 110 and 150 GeV. The analysis of the data excludes, at 95% confidence level, the standard model Higgs boson decaying into two photons in the mass range 128 to 132 GeV. The largest excess of events above the expected standard model background is observed for a Higgs boson mass hypothesis of 124 GeV with a local significance of 3.1 sigma. The global significance of observing an excess with a local significance greater than 3.1 sigma anywhere in the search range 110-150 GeV is estimated to be 1.8 sigma. More data are required to ascertain the origin of this excess.Comment: Submitted to Physics Letters

Blended versus face-to-face: comparing student performance in a therapeutics class

Therapeutics is a very complex subject for every pharmacy student, since it requires the application of knowledge from several other disciplines. The study of therapeutics is often done in case-based learning in order to promote reflective thinking and give a scenario as real as possible. The objective of this study was to compare student performance between faceto-face (n = 54) and blended learning (n = 56) approaches to the teaching of therapeutics. They can confirm that there are statistically significant differences (p < 0.05) between the final exam scores from both groups, being that the b learning group achieved higher scores. Blended learning seems to be an effective way to teach therapeutics, following pre established teaching methods, and above all, does not negatively affect student performance. It also provides new learning environments and strategies, and promotes the development of new skills such as learning and collaborating online, which may be relevant in a networked knowledge society.info:eu-repo/semantics/publishedVersio

Measurement of the Lambda(b) cross section and the anti-Lambda(b) to Lambda(b) ratio with Lambda(b) to J/Psi Lambda decays in pp collisions at sqrt(s) = 7 TeV

The Lambda(b) differential production cross section and the cross section ratio anti-Lambda(b)/Lambda(b) are measured as functions of transverse momentum pt(Lambda(b)) and rapidity abs(y(Lambda(b))) in pp collisions at sqrt(s) = 7 TeV using data collected by the CMS experiment at the LHC. The measurements are based on Lambda(b) decays reconstructed in the exclusive final state J/Psi Lambda, with the subsequent decays J/Psi to an opposite-sign muon pair and Lambda to proton pion, using a data sample corresponding to an integrated luminosity of 1.9 inverse femtobarns. The product of the cross section times the branching ratio for Lambda(b) to J/Psi Lambda versus pt(Lambda(b)) falls faster than that of b mesons. The measured value of the cross section times the branching ratio for pt(Lambda(b)) > 10 GeV and abs(y(Lambda(b))) < 2.0 is 1.06 +/- 0.06 +/- 0.12 nb, and the integrated cross section ratio for anti-Lambda(b)/Lambda(b) is 1.02 +/- 0.07 +/- 0.09, where the uncertainties are statistical and systematic, respectively.Comment: Submitted to Physics Letters
