EFEITO DA BIOESTIMULAÇÃO, MONENSINA E SOMATOTROPINA RECOMBINANTE BOVINA SOBRE O GANHO MÉDIO DIÁRIO E INÍCIO DA PUBERDADE EM NOVILHAS GIROLANDO CRIADAS A PASTO

To evaluate the effect of three management strategies on ovarian function of Girolando heifers raised in a pasture-based system, 80 females with 10 months of age and weight 169,3 ± 26,4 kg were divided in eight groups and submitted by 180 days to the treatments: Control (T1); Biostimulation (T2); Monensin (T3); Recombinant bovine somatotropin (BST) (T4); Biostimulation and Monensin (T5); Biostimulation and BST (T6); Monensin and BST (T7); Biostimulation, Monensin and BST (T8). Oestrus activity was evaluated daily and heifers were weighted every 15 days. Starting from the 15th month of age animals were submitted to ovarian evaluation by ultrasound to verify follicles and corpus luteum. Daily weight gain (kg) was 0,52 ± 0,02 (T1); 0,42 ± 0,03 (T2); 0,68 ± 0,04 (T3); 0,43 ± 0,03 (T4); 0,42 ± 0,04 (T5); 0,42 ± 0,02 (T6); 0,70 ± 0,04 (T7) and 0,53 ± 0,01 (T8), with differences (P<0,05). Weight on the 16th month of age varied from 270 kg (T2) to 323 kg (T3), with differences (P<0,05). The signals of oestrus where observed in females starting from the 13th month of age and the higher concentration of these signals being observed at the 14th (T8) and 15th (T3), compatible with the ovarian activity to the 15 months when the animals of these groups had antral follicles or corpus luteum. The present results allow to conclude that the offer of monensin to pre-pubertal Girolando heifers, alone or in association with bioestimulation and BST allows homogenizing the age at puberty in pasture-based systems, reducing the age of the first service and calving.Com o objetivo de avaliar o efeito de três estratégias de manejo sobre a função ovariana de novilhas Girolando criadas a pasto, 80 fêmeas com 10 meses de idade e peso de 169,3 ± 26,4 kg foram alocadas em oito grupos e submetidas por 180 dias aos tratamentos: Controle (T1); Bioestimulação (T2); Monensina (T3); Somatotropina Recombinante Bovina - rBST (T4); Bioestimulação e Monensina (T5); Bioestimulação e rBST (T6); Monensina e rBST (T7); Bioestimulação, Monensina e rBST (T8). A atividade estral foi avaliada diariamente e os pesos tomados a cada 15 dias. Entre 15 e 16 meses de idade as fêmeas foram submetidas à ultra-sonografia ovariana, a fim de verificar folículos e corpos lúteos. O ganho médio diário (kg) foi 0,52 ± 0,02 (T1); 0,42 ± 0,03 (T2); 0,68 ± 0,04 (T3); 0,43 ± 0,03 (T4); 0,42 ± 0,04 (T5); 0,42 ± 0,02 (T6); 0,70 ± 0,04 (T7) e 0,53 ± 0,01 (T8), verificando-se diferenças entre eles (P<0,05). O peso aos 16 meses variou de 270 kg (T2) a 323 kg (T3), com diferenças (P<0,05). Os sinais de estro foram observados nas fêmeas a partir de 13 meses de idade e verificou-se maior concentração destes sinais aos 14 (T8) e aos 15 meses (T3), compatível com a atividade ovariana aos 15/16 meses, quando os animais destes grupos tinham folículos antrais e/ou corpos lúteos. Estes resultados permitem concluir que a adição de monensina à alimentação de fêmeas Girolando pré-púberes isolada ou associada com bioestimulação e aplicação de rBST permite homogeneizar a idade à puberdade de animais criados a pasto, reduzindo a idade ao primeiro serviço e parto

Search for direct production of charginos and neutralinos in events with three leptons and missing transverse momentum in √s = 7 TeV pp collisions with the ATLAS detector

A search for the direct production of charginos and neutralinos in final states with three electrons or muons and missing transverse momentum is presented. The analysis is based on 4.7 fb−1 of proton–proton collision data delivered by the Large Hadron Collider and recorded with the ATLAS detector. Observations are consistent with Standard Model expectations in three signal regions that are either depleted or enriched in Z-boson decays. Upper limits at 95% confidence level are set in R-parity conserving phenomenological minimal supersymmetric models and in simplified models, significantly extending previous results

Jet size dependence of single jet suppression in lead-lead collisions at sqrt(s(NN)) = 2.76 TeV with the ATLAS detector at the LHC

Measurements of inclusive jet suppression in heavy ion collisions at the LHC provide direct sensitivity to the physics of jet quenching. In a sample of lead-lead collisions at sqrt(s) = 2.76 TeV corresponding to an integrated luminosity of approximately 7 inverse microbarns, ATLAS has measured jets with a calorimeter over the pseudorapidity interval |eta| < 2.1 and over the transverse momentum range 38 < pT < 210 GeV. Jets were reconstructed using the anti-kt algorithm with values for the distance parameter that determines the nominal jet radius of R = 0.2, 0.3, 0.4 and 0.5. The centrality dependence of the jet yield is characterized by the jet "central-to-peripheral ratio," Rcp. Jet production is found to be suppressed by approximately a factor of two in the 10% most central collisions relative to peripheral collisions. Rcp varies smoothly with centrality as characterized by the number of participating nucleons. The observed suppression is only weakly dependent on jet radius and transverse momentum. These results provide the first direct measurement of inclusive jet suppression in heavy ion collisions and complement previous measurements of dijet transverse energy imbalance at the LHC.Comment: 15 pages plus author list (30 pages total), 8 figures, 2 tables, submitted to Physics Letters B.

‘No memory, no desire’: psychoanalysis in Brazil during repressive times

Until recently, the growth and significance of Brazilian psychoanalysis has been neglected in histories of psychoanalysis. Not only is this history long and rich in its professional and cultural dimensions, but there was an especially important ‘event’ – the so-called ‘Cabernite-Lobo affair’ – that took place during the period of the military dictatorship, which can be seen as dramatising some of the issues concerning the erasure of memory in psychoanalysis, especially in connection with political difficulties. In this paper, we provide an outline of the origins and dissemination of psychoanalysis in Brazil before looking again at the Cabernite-Lobo affair in order to examine in a situated way how psychoanalysis engages with political extremism, and particularly to explore the consequences of an unthinking generalisation of the idea of ‘neutrality’ from the consulting room to the institutional setting. We draw especially on Brazilian papers in Portuguese, which have not been accessible in the English-language psychoanalytic literature

Global extent and drivers of mammal population declines in protected areas under illegal hunting pressure

Illegal hunting is a persistent problem in many protected areas, but an overview of the extent of this problem and its impact on wildlife is lacking. We reviewed 40 years (1980–2020) of global research to examine the spatial distribution of research and socio-ecological factors influencing population decline within protected areas under illegal hunting pressure. From 81 papers reporting 988 species/site combinations, 294 mammal species were reported to have been illegally hunted from 155 protected areas across 48 countries. Research in illegal hunting has increased substantially during the review period and showed biases towards strictly protected areas and the African continent. Population declines were most frequent in countries with a low human development index, particularly in strict protected areas and for species with a body mass over 100 kg. Our results provide evidence that illegal hunting is most likely to cause declines of large-bodied species in protected areas of resource-poor countries regardless of protected area conservation status. Given the growing pressures of illegal hunting, increased investments in people’s development and additional conservation efforts such as improving anti-poaching strategies and conservation resources in terms of improving funding and personnel directed at this problem are a growing priority
