    Does Sex Matter? Ageing and Ability to Conceive

    Get PDF
    Recently there has been increasing interest in the estimation of age-specific fecundability as a result of the progressive postponement of age at family formation in Western countries. It must be noted, however, that the possible negative effects of the postponement could act not only on the physiological component of the ability to conceive but also on the behavioural component (i.e., sexual activity). The main aim of our study was to verify if, the desire to have a child being equal, the coital frequency decreases in one’s 30s as compared to the 20s. For our analysis we used the data from the Multinational Study in Daily Fecundability (MSDF), which has produced a very rich database with behavioural and physiological information prospectively collected on every cycle. We found empirical evidence that the desire to have a child only partially compensates for the decline of coital frequency with age.

    Time-Varying Spot and Futures Oil Price Dynamics

    We investigate the role of crude oil spot and futures prices in the process of price discovery by using a cost-of-carry model with an endogenous convenience yield and daily data over the period from January 1990 to December 2008. We provide evidence that futures markets play a more important role than spot markets in the case of contracts with shorter maturities, but the relative contribution of the two types of market turns out to be highly unstable, especially for the most deferred contracts. The implications of these results for hedging and forecasting crude oil spot prices are also discussed.Cointegration, oil market, futures prices, price discovery

    Get PDF
    A Large Ion Collider Experiment - ALICE will become operational with the startup of the Large Hadron Collider - LHC at the end of 2007. One focus of the physics program is the measurement of quarkonia in proton-proton and lead-lead collisions. Quarkonia states will be measured in two kinematic regions and channels: di-muonic decays will be measured in the forward region by the muon arm, the central part of the detector will measure di-electronic decays. The presented studies show the expected performance of the di-electron measurement in proton-proton and central lead-lead collisions.Comment: 6 pages, 7 figures, Proceedings of the QM 2006 poster sessio

    Genome-wide association analysis of grain yield-associated traits in a pan-European barley cultivar collection

    Get PDF
    A collection of 379 Hordeum vulgare cultivars, comprising all combinations of spring and winter growth habits with two and six row ear type, was screened by genome wide association analysis to discover alleles controlling traits related to grain yield. Genotypes were obtained at 6,810 segregating gene-based single nucleotide polymorphism (SNP) loci and corresponding field trial data were obtained for eight traits related to grain yield at four European sites in three countries over two growth years. The combined data were analyzed and statistically significant associations between the traits and regions of the barley genomes were obtained. Combining this information with the high resolution gene map for barley allowed the identification of candidate genes underlying all scored traits and superposition of this information with the known genomics of grain trait genes in rice resulted in the assignation of 13 putative barley genes controlling grain traits in European cultivated barley. Several of these genes are associated with grain traits in both winter and spring barley

    How Anesthetic, Analgesic and Other Non-Surgical Techniques During Cancer Surgery Might Affect Postoperative Oncologic Outcomes:A Summary of Current State of Evidence

    Get PDF
    The question of whether anesthetic, analgesic or other perioperative intervention during cancer resection surgery might influence long-term oncologic outcomes has generated much attention over the past 13 years. A wealth of experimental and observational clinical data have been published, but the results of prospective, randomized clinical trials are awaited. The European Union supports a pan-European network of researchers, clinicians and industry partners engaged in this question (COST Action 15204: Euro-Periscope). In this narrative review, members of the Euro-Periscope network briefly summarize the current state of evidence pertaining to the potential effects of the most commonly deployed anesthetic and analgesic techniques and other non-surgical interventions during cancer resection surgery on tumor recurrence or metastasis

    Variabilidade espacial do microclima em sistema compost barn: influência na qualidade da cama, termorregulação e comportamento de vacas leiteiras

    The objective of this research was to verify if the spatial variability of the microclimate in the compost barn system has influence on the thermoregulation and behavior of dairy cows and on bed quality. The experiment was carried out between October 2017 and February 2018, with evaluations performed preferably at weekends, in private property located in the interior of the municipality of Dois Vizinhos - Paraná. We used 18 cows of the Dutch breed x Jersey which were divided into two treatments according to the order of lactation. The first treatment consisted of primiparous cows and the second was multiparous cows. Evaluations were made regarding thermoregulation through respiratory rate and surface temperature; microclimatic assessments (air temperature, relative air humidity and wind speed) and; temperature and humidity of the bed, to evaluate the spatial variability of these variables, microclimatic evaluations for thermal comfort indices and behavioral evaluations. The data regarding spatial variability were analyzed through geostatistics and the data referring to the indices of thermal comfort, thermoregulation and behavior were analyzed through Bayesian inference. The thermal environment of the microclimate of compost barn presented spatial dependence for all analyzed variables. Thermal comfort indexes indicated that compost barn provided conditions for the animals to remain in thermal comfort, which was confirmed by the respiratory rate and surface temperature of the animals' fur. Although comfort indexes and physiological responses indicated thermal comfort, cow behaviors were shaped by the thermal environment and social structure, with differences between treatments for eating behavior, water intake, gait and rest leisure. The results found in this research indicate that compost barn is a system capable of providing thermal comfort conditions for dairy cows. However, a well-sized ventilation system is required throughout the installation area so that the movement of the air mass refreshes the animals and helps to remove the moisture from the bed.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Objetivou-se através dessa pesquisa, verificar se a variabilidade espacial do microclima em sistema compost barn possui influência na termorregulação e comportamento de vacas leiteiras e na qualidade da cama. O experimento foi realizado entre outubro de 2017 e fevereiro de 2018, com avaliações realizadas preferencialmente aos fins de semana, em propriedade particular localizada no interior do município de Dois Vizinhos - Paraná. Foram utilizadas 18 vacas da raça holandesa x Jersey às quais foram divididas em dois tratamentos de acordo com a ordem de lactação. O primeiro tratamento foi constituído por vacas primíparas e o segundo por vacas multíparas. Foram realizadas avaliações referentes a termorregulação através da frequência respiratória e temperatura superficial; avaliações microclimáticas (temperatura do ar, umidade relativa do ar e velocidade do vento) e; temperatura e umidade da cama, para avaliação da variabilidade espacial dessas variáveis, avaliações microclimáticas para realizações dos índices de conforto térmico e avaliações comportamentais. Os dados referentes a variabilidade espacial foram analisados através da geoestatística e os dados referentes aos índices de conforto térmico, termorregulação e comportamento foram analisados através da inferência bayesiana. O ambiente térmico do microclima do compost barn apresentou dependência espacial para todas variáveis analisadas. Os índices de conforto térmico apontam que o compost barn forneceu condições para que os animais se mantivessem em conforto térmico, o que foi confirmado pela frequência respiratória e temperatura da superfície do pelame dos animais. Embora os índices de conforto e as respostas fisiológicas indicassem conforto térmico, os comportamentos das vacas foram moldados pelo ambiente térmico e estrutura social, com diferença entre tratamentos para o comportamento comer, ingerir água, andar e de ócio deitado. Os resultados encontrados nessa pesquisa apontam que o compost barn é um sistema capaz de fornecer condições de conforto térmico para vacas leiterias. Contudo, é necessário um sistema de ventilação bem dimensionado em toda área da instalação para que a movimentação da massa de ar refresque os animais e auxilie na remoção da umidade da cama
