Renewed interest in heat stress effects on livestock productivity derives from climate change, which is expected to increase temperatures and the frequency of extreme weather events. This study aimed at evaluating the effect of temperature and humidity on milk production in highly selected dairy cattle populations across three European regions differing in climate and production systems to detect differences and similarities that can be used to optimize heat stress (HS) effect modeling. Milk, fat and protein test day data from official milk recording for years 1999 to 2010 in four Holstein populations located in the Walloon Region of Belgium (BEL), Luxembourg (LUX), Slovenia (SLO) and Southern Spain (SPA) were merged with temperature and humidity data provided by the state meteorological agencies. After merging, the number of test day records/cows per trait ranged from 686,726/49,655 in SLO to 1,982,047/136,746 in BEL. Values for the daily average and maximum temperature and humidity index (THIavg and THImax) ranges for THIavg/THImax were largest in SLO (22-74/28-84) in SLO and shortest in SPA (39-76/46-83). Change point techniques were used to determine comfort thresholds, which differed across traits and climatic regions. Milk yield showed an inverted U shaped pattern of response across the THI scale with a HS threshold around 73 THImax units. For fat and protein, thresholds were lower than for milk yield and were shifted around 6 THI units towards larger values in SPA compared with the other countries. Fat showed lower HS thresholds than protein traits in all countries. The traditional broken line model was compared to quadratic and cubic fits of the pattern of response in production to increasing heat loads. A cubic polynomial model allowing for individual variation in patterns of response and THIavg as heat load measure showed the best statistical features. Higher/lower producing animals showed less/more persistent production (quantity and quality) across the THI scale. The estimated correlations between comfort and THIavg values of 70 (which represents the upper end of the THIavg scale in BEL-LUX) were lower for BEL-LUX (0.70 - 0.80) than for SPA (0.83 - 0.85). Overall, animals producing in the more temperate climates and semi-extensive grazing systems of BEL and LUX showed HS at lower heat loads and more re-ranking across the THI scale than animals producing in the warmer climate and intensive indoor system of SPA.

The challenge of managing and breeding dairy cows is permanently adapting to changing production circumstances under socio-economic constraints. If managing and breeding address different timeframes of action, both need relevant phenotypes that allow for precise monitoring of the status of the cows, and their health, behavior, and well-being as well as their environmental impact and the quality of their products (i.e., milk and subsequently dairy products). Milk composition has been identified as an important source of information because it could reflect, at least partially, all these elements. Major conventional milk components such as fat, protein, urea, and lactose contents are routinely predicted by mid-infrared (MIR) spectrometry and have been widely used for these purposes. But, milk composition is much more complex and other nonconventional milk components, potentially predicted by MIR, might be informative. Such new milk-based phenotypes should be considered given that they are cheap, rapidly obtained, usable on a large scale, robust, and reliable. In a first approach, new phenotypes can be predicted from MIR spectra using techniques based on classical prediction equations. This method was used successfully for many novel traits (e.g., fatty acids, lactoferrin, minerals, milk technological properties, citrate) that can be then useful for management and breeding purposes. An innovation was to consider the longitudinal nature of the relationship between the trait of interest and the MIR spectra (e.g., to predict methane from MIR). By avoiding intermediate steps, prediction errors can be minimized when traits of interest (e.g., methane, energy balance, ketosis) are predicted directly from MIR spectra. In a second approach, research is ongoing to detect and exploit patterns in an innovative manner, by comparing observed with expected MIR spectra directly (e.g., pregnancy). All of these traits can then be used to define best practices, adjust feeding and health management, improve animal welfare, improve milk quality, and mitigate environmental impact. Under the condition that MIR data are available on a large scale, phenotypes for these traits will allow genetic and genomic evaluations. Introduction of novel traits into the breeding objectives will need additional research to clarify socio-economic weights and genetic correlations with other traits of interest. [less ▲]

In this research, the influence on energy balance of the discretization scheme of the divergence formulation of the bed slope term in the shallow-water equations is analysed theoretically (for a single topographic step) and based on two numerical tests. Different values of the main parameter controlling the discretization scheme of the divergence formulation are analysed to identify the formulation which minimizes the energy variation resulting from the discretization. For a wide range of ambient Froude numbers and relative step heights, the theoretical value of the control parameter minimizing the energy variation falls within a very narrow range, which can reasonably be approximated by a single “optimal” value. This is a result of high practical relevance for the design of accurate numerical schemes, as confirmed by the results of the numerical tests. [less ▲]

The video industry in Nigeria has developed within a widely informal economic environment in which the illicit reproduction and circulation of goods were the rule rather than the exception. The informality of circulation has played a particularly influential role in both the history of the video industry and the genesis of the present crisis. While, on the one hand, it has made videos available all over the African continent and within the diaspora, creating the basis for Nollywood’s international success, it has, on the other hand, weakened the industry’s economy, exposing it to consecutive cycles of saturation and collapse. For this reason, the production crisis that emerged over the past few years has catalyzed numerous controversies concerning the structure of the video economy and the rules that regulate it. The informality on which the video economy has been based since its inception is today often considered a threat to the survival of the industry itself. While the industry has achieved global recognition, the economic fragility of its success has provoked growing anxiety. This anxiety has been progressively concentrated, by both media and video entrepreneurs, on issues of piracy and copyright protection. The aim of this chapter is to investigate the causes of this anxiety and the role that piracy and transformations in copyright legislation have had in catalysing it, while shaping the economy of the industry. Throughout this chapter I will argue that when the uncontrolled circulation of goods begins to undermine the economic basis of the industry that produces them, the rhetoric of piracy is mobilized to ensure the accessibility to the economy of both the production and the distribution of the goods themselves. This allows some of the entrepreneurs involved in the production process to gain exclusive control over it and the capital it generates. Within the Nigerian context, the rhetorical construction of piracy and the legal and economic consequences of this construction are the result of specific conflicts among different segments of the Nigerian video industry and, more precisely, different models of economic entrepreneurship. As the history of the Nigerian video phenomenon shows, a loose copyright regime seems to have positive consequences for the emergence and early development of a creative industry, although, once the industry seeks to attain higher levels of profitability, it tends to become problematic, and the rhetoric of piracy can become a tool to orient processes of restructuration of the cultural industry’s economy. In relation to this dynamic, I analyse the way in which the normative orders that regulate the reproduction and circulation of images and contents developed within the Nigerian context, and I discuss how their introduction and implementation progressively shaped people’s perception of legal and illegal practices in the field of local cultural production.

Introduction Adherence to therapy is a relevant challenge in chronic hemodialysis patients. The directly observed therapy (DOT) could be an effective method to increase adherence for specific therapies. We aimed to study the performance of DOT versus home medication. We follow the impact of providing native vitamin D directly by the nurse after a dialysis session on the 25-hydroxyvitamin [25(OH)D] concentrations. Methods In this observational study, we included 38 dialysis patients treated by stable dosage of cholecalciferol. DOT was implemented in December 2010. We considered the concentrations of 25-OH vitamin D three times before (T1 = June 2010, T2 = July 2010 and T3 = September 2010) and three times after the modification of prescription (T4 = February 2011, T5 = March 2011 and T6 = April 2011). Results Median age was 72 [62; 79] years and 48 % were diabetics. Mean body mass index was 26 ± 5 kg/m2 and median dialysis vintage was 20 [8; 46] months. The patients were compared to themselves. Before DOT, median concentrations of 25(OH)D were 27 (14–36), 23 (17–31), 31 (22–38) ng/mL at T1, T2 and T3, respectively. When DOT was effective, the concentrations significantly increased to 34 (28–44), 35 (29–41), 39 (32–47) ng/mL at T4, T5 and T6, respectively. Before DOT, 19 patients (50 %) reached the target of 30 ng/mL. After DOT, 29 patients (76 %) reached the target concentration of 30 ng/ mL. Conclusions In hemodialysis patients, DOT is both simple and effective to increase the therapeutic impact to native vitamin D. [less ▲]

In the fight against terrorism States have resorted to a variety of weapons. Much attention has been devoted to criminal law as a possible answer to terrorism. Many States have also resorted to nationality law, using deprivation as a means to punish those involved in terrorism. This paper will focus on Belgium and France. These two countries indeed present striking similarities. Both in France and Belgium the provisions on deprivation already made it possible to deprive a national of his citizenship in terrorist cases. Nevertheless, the legislation in these countries has been recently modified to offer yet a stronger answer to terrorism. The public debate in the two countries is modelled on similar lines. This is in particular true for the issue of equality arising in connection of deprivation of nationality. The paper will first offer an overview of the existing statutory provisions in the two countries, before critically reviewing the discussion on equality and non discrimination. [less ▲]

We present a thorough investigation by magneto-optical imaging of the magnetic flux penetration in Nb thin films with lithographically defined border indentations. We demonstrate that discontinuity lines (d-lines), caused by the abrupt bending of current streamlines around the indentations, depart from the expected parabolic trend close to the defect and depend on the shape and size of the indentation as well as on the temperature. These findings are backed up and compared with theoretical results obtained by numerical simulations and analytical calculations highlighting the key role played by demagnetization effects and the creep exponent n. In addition, we show that the presence of nearby indentations and submicrometer random roughness of the sample border can severely modify the flux front topology and dynamics. Strikingly, in contrast to what has been repeatedly predicted in the literature, we do not observe that indentations act as nucleation spots for flux avalanches, but they instead help to release the flux pressure and avoid thermomagnetic instabilities.
