Quimerismo 60,xx/60,xy e freemartismo em bovinos nascidos de partos gemelares heterossexuais.

Foram estudados citogeneticamente 42 bovinos nascidos de partos gemelares heterossexuais, sendo 10 casais, 19 fêmeas e três machos de várias raças, principalmente, Holandesa (17) e Pardo Suíça (11), pertencentes ao Instituto de Zootecnia-APTA, Nova Odessa, SP, e a produtores particulares de outras regiões do Estado. A análise citogenética foi realizada em metáfases obtidas após culturas de linfócitos. Em 90,5% (38) dos animais, foi observado o quimerismo 60,XX/ 60,XY com 1,8 a 90,2% de células femininas. Considerando todos os animais quiméricos, foram analisadas 3806 células, sendo 1268 XX (33,3%) e 2538 XY (66,7%). Em nove casais, as freqüências de células femininas foram 24,8 e 21,5% e as de masculinas de 75,2 e 78,5% para fêmeas e machos, respectivamente. Em um casal, não foi evidenciada troca de células, e a fêmea apresentou somente células de linhagem feminina e o macho, de linhagem masculina. Três das fêmeas avaliadas eram adultas e foram abatidas. Seus aparelhos genitais apresentaram vários graus de masculinização como: aumento do clitóris, subdesenvolvimento da vagina, da cérvix (ausente em uma fêmea), do útero, das tubas uterinas, presença de glândulas vesiculares e gônadas ovotestis, (testículos e pênis rudimentares foram encontrados em uma fêmea). O cariótipo 60,XX foi observado em apenas três fêmeas das 29 analisadas: duas delas apresentaram todas as características de fêmea normal e inclusive pariram com aproximadamente 30 meses de idade; a outra fêmea ainda não atingiu a idade de reprodução, mas parece apresentar função reprodutiva normal. Dos 13 machos analisados, 12 apresentaram quimerismo 60,XX/60,XY e um apresentou cariótipo normal (60,XY). A análise citogenética é um meio eficaz e pouco oneroso de constatar freemartismo em fêmea bovina gêmea com macho, permitindo o diagnóstico precoce e a oportunidade de eliminação do processo reprodutivo os animais portadores de quimerismo, de maneira a baixar os custo com manejo e a diminuir a freqüência desta anomalia nos rebanhos

Five-Dimensional QED, Muon Pair Production and Correction to the Coulomb Potential

We consider QED in five dimensions in a configuration where matter is localized on a 3-brane while foton propagates in the bulk. The idea is to investigate the effects of the Kaluza-Klein modes of the photon in the relativistic regime, but in low energy, and in the nonrelativistic regime. In the relativistic regime, we calculate the cross section for the reaction $e^+ + e^- \to \mu^+ + \mu^-$. We compare our theoretical result with a precise measurement of this cross section at $\sqrt{s}=57.77$ GeV. As result, we extract a lower bound on the size of the extra dimension. In the nonrelativistic regime, we derive the contribution for the Coulomb potential due to the whole tower of the Kaluza-Klein excited modes of the photon. We use the modified potential to calculate the Rutherford scattering differential cross section.Comment: minor changes, three new refs. added, to appear in IJMP

The Role of Psychosocial Factors in Wellbeing and Self-Care in Young Adults with Type 1 Diabetes

The purpose of this study is to explore the relationship between glycaemic control, locus of control beliefs, diabetes knowledge and wellbeing in young adults with type 1 diabetes. A cross-sectional study of forty-two young adults (16-25 years) with type 1 diabetes recruited from two diabetes clinics in London. Participants completed postal questionnaires designed for this specific population. Wellbeing was assessed by the W-B12, locus of control by the ADDLoC and diabetes knowledge by the ADKnowl. HbA1c was employed as a measure of glycaemic control. Results indicated that external (health professionals) and internal locus of control beliefs and diabetes knowledge were significantly associated with psychological wellbeing. Patients place high expectations on their practitioners and accordingly, practitioners need to address patients’ diabetes knowledge to help them to manage their diabetes effectively and independently. The relationship between internal and external locus of control beliefs, diabetes knowledge and wellbeing indicates the importance of addressing empowerment and self-efficacy in psychoeducation interventions for this client group

Research on quality management and sustainability

Purpose - This article aims to ascertain the necessity for specific research on quality management approaches, bringing to the discussion some concerns and challenges to the quality movement, especially in development of new methodologies for supporting design in the digital area. Design/methodology/approach - Firstly, papers were researched that had already studied the question of what research should carry out in response to the great scientific, technical, and social changes, specifically to support design activities for internet products and secondly we concluded what development is needed. Findings - The increasing complexity of management and technology creates many situations of anxiety and distress, which often translate into abandonment of proven techniques and methodologies, leading to intuitive approaches. But complexity requires more techniques and methodologies not less. The quality movement faces a serious challenge: how to design in an ethical perspective these types of products. Research limitations/implications - This research is limited to identify some needs, but future research should be done in characterizing existing answers and identifying what development is needed. Practical implications - The above findings and reflections can help other researchers to focus on design, to find out practical solutions for sustainability in the innovation process of products and services. Social implications - Finding out to design in an ethical perspective products and services for internet. Originality/value - This research identified relevant challenges the quality management is facing, and it gives guidelines for defining research lines.info:eu-repo/semantics/publishedVersio

XMM-Newton observations of the low-luminosity cataclysmic variable V405 Pegasi

V405 Peg is a low-luminosity cataclysmic variable (CV) that was identified as the optical counterpart of the bright, high-latitude ROSAT all-sky survey source RBS1955. The system was suspected to belong to a largely undiscovered population of hibernating CVs. Despite intensive optical follow-up its subclass however remained undetermined. We want to further classify V405 Peg and understand its role in the CV zoo via its long-term behaviour, spectral properties, energy distribution and accretion luminosity. We perform a spectral and timing analysis of \textit{XMM-Newton} X-ray and ultra-violet data. Archival WISE, HST, and Swift observations are used to determine the spectral energy distribution and characterize the long-term variability. The X-ray spectrum is characterized by emission from a multi-temperature plasma. No evidence for a luminous soft X-ray component was found. Orbital phase-dependent X-ray photometric variability by $\sim50\%$ occurred without significant spectral changes. No further periodicity was significant in our X-ray data. The average X-ray luminosity during the XMM-Newton observations was L_X, bol simeq 5e30 erg/s but, based on the Swift observations, the corresponding luminosity varied between 5e29 erg/s and 2e31 erg/son timescales of years. The CV subclass of this object remains elusive. The spectral and timing properties show commonalities with both classes of magnetic and non-magnetic CVs. The accretion luminosity is far below than that expected for a standard accreting CV at the given orbital period. Objects like V405 Peg might represent the tip of an iceberg and thus may be important contributors to the Galactic Ridge X-ray Emission. If so they will be uncovered by future X-ray surveys, e.g. with eROSITA.Comment: A&A, in pres

Universality of weakly bound dimers and Efimov trimers close to Li-Cs Feshbach resonances

We study the interspecies scattering properties of ultracold Li-Cs mixtures in their two energetically lowest spin channels in the magnetic field range between 800 G and 1000 G. Close to two broad Feshbach resonances we create weakly bound LiCs dimers by radio-frequency association and measure the dependence of the binding energy on the external magnetic field strength. Based on the binding energies and complementary atom loss spectroscopy of three other Li-Cs s-wave Feshbach resonances we construct precise molecular singlet and triplet electronic ground state potentials using a coupled-channels calculation. We extract the Li-Cs interspecies scattering length as a function of the external field and obtain almost a ten-fold improvement in the precision of the values for the pole positions and widths of the s-wave Li-Cs Feshbach resonances as compared to our previous work [Pires \textit{et al.}, Phys. Rev. Lett. \textbf{112}, 250404 (2014)]. We discuss implications on the Efimov scenario and the universal geometric scaling for LiCsCs trimers

An efficient numerical integration algorithm for the single mode compressible Leonov model – Complas XI

In this contribution, an algorithm for numerical integration of the Leonov elastoviscoplastic model is proposed. The operator split methodology and the Newton-Raphson method are used to derive the state update algorithm and obtain the numerical solution of the discretized evolution equations. Particular effort is devoted to the reduction of the number of required residual equations in order to have a more efficient numerical implementation. The consistent tangent module is expressed in a closed form as a result of the exact linearization of the discretized evolution equations. The performance of the algorithm is validated through comparison with existing experimental data
