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 fĂȘmeas e trĂȘs machos de vĂĄrias raças, principalmente, Holandesa (17) e Pardo SuĂça (11), pertencentes ao Instituto de Zootecnia-APTA, Nova Odessa, SP, e a produtores particulares de outras regiĂ”es do Estado. A anĂĄlise citogenĂ©tica foi realizada em metĂĄfases obtidas apĂłs culturas de linfĂłcitos. Em 90,5% (38) dos animais, foi observado o quimerismo 60,XX/ 60,XY com 1,8 a 90,2% de cĂ©lulas femininas. Considerando todos os animais quimĂ©ricos, foram analisadas 3806 cĂ©lulas, sendo 1268 XX (33,3%) e 2538 XY (66,7%). Em nove casais, as freqĂŒĂȘncias de cĂ©lulas femininas foram 24,8 e 21,5% e as de masculinas de 75,2 e 78,5% para fĂȘmeas e machos, respectivamente. Em um casal, nĂŁo foi evidenciada troca de cĂ©lulas, e a fĂȘmea apresentou somente cĂ©lulas de linhagem feminina e o macho, de linhagem masculina. TrĂȘs das fĂȘmeas avaliadas eram adultas e foram abatidas. Seus aparelhos genitais apresentaram vĂĄrios graus de masculinização como: aumento do clitĂłris, subdesenvolvimento da vagina, da cĂ©rvix (ausente em uma fĂȘmea), do Ăștero, das tubas uterinas, presença de glĂąndulas vesiculares e gĂŽnadas ovotestis, (testĂculos e pĂȘnis rudimentares foram encontrados em uma fĂȘmea). O cariĂłtipo 60,XX foi observado em apenas trĂȘs fĂȘmeas das 29 analisadas: duas delas apresentaram todas as caracterĂsticas de fĂȘmea normal e inclusive pariram com aproximadamente 30 meses de idade; a outra fĂȘmea ainda nĂŁo 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 cariĂłtipo normal (60,XY). A anĂĄlise citogenĂ©tica Ă© um meio eficaz e pouco oneroso de constatar freemartismo em fĂȘmea bovina gĂȘmea com macho, permitindo o diagnĂłstico 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 freqĂŒĂȘncia 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 . We compare our theoretical result with a precise
measurement of this cross section at 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 patientsâ 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 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 â 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
