A QTL detection experiment was performed in French dairy cattle to search for QTL related to male fertility. Ten families, involving a total of 515 bulls, were phenotyped for ejaculated volume and sperm concentration, number of spermatozoa, motility, velocity, percentage of motile spermatozoa after thawing and abnormal spermatozoa. A set of 148 microsatellite markers were used to realize a genome scan. First, genetic parameters were estimated for all traits. Semen production traits were found to have moderate heritabilities (from 0.15 to 0.30) while some of the semen quality traits such as motility had high heritabilities (close to 0.60). Genetic correlations among traits showed negative relationships between volume and concentration and between volume and most quality traits such as motility or abnormal sperm while correlations between concentration and these traits were rather favourable. Percentages of abnormal sperm were negatively related to quality traits, especially with motility and velocity of spermatozoa. Three QTL related to abnormal sperm frequencies were significant at p < 0.01. In total, 11 QTL (p < 0.05) were detected. However, the number of QTL detected was within the range of expected false positives. Because of the lack of power to find QTL in this design further analyses are required to confirm these QTL.

Relativistic Hartree–Fock and multiconfigurational Dirac–Fock calculations of atomic structure and transition rates have been carried out in trebly ionized lanthanum (La3+, Z = 57). The calculations have to cope with configuration interaction effects but also with the very complex situation of the collapse of the 4f wave function. The calculations are compared to experimental data obtained with beam-foil spectroscopy in the extreme ultraviolet, at ion energies that favour <br />the production of the spectrum La IV. Besides lines known from sliding spark discharges, many more lines are observed that have not yet been identified. Time-resolved measurements yield three level lifetimes in La IV that agree roughly with the results of our own calculations. [less ▲]

We solve the entanglement classification under stochastic local operations and classical communication (SLOCC) for all multipartite symmetric states in the general N-qubit case. For this purpose, we introduce 2 parameters playing a crucial role, namely, the diversity degree and the degeneracy configuration of a symmetric state. Those parameters give rise to a simple method of identifying operational families of SLOCC entanglement classes of all symmetric N-qubit states, where the number of families grows as the partition function of the number of qubits.

The complex {Fe[HC(3-Mepz)2(5-Mepz)]2}(BF4)2 (pz = pyrazolyl ring) has been prepared by the reaction of HC(3-Mepz)2(5-Mepz) with Fe(BF4)2·6H2O. The solid state structures obtained at 294 and 150 K show a distorted iron(II) octahedral N6 coordination environment with the largest deviations arising from the restrictions imposed by the chelate rings. At 294 K the complex is predominately high-spin with Fe–N bond distances averaging 2.14 Å, distances that are somewhat shorter than expected for a purely high-spin iron(II) complex because of the presence of an admixture of ca. 70 (I get 80 from both mag and X-ray, 3/15, where 3 is the subtraction of 2.14 and 2.17 and 15 1.99 and 2.14 and from Figure 3b) percent high-spin and 30 (20) percent low-spin iron(II). At 294 K the twisting of the pyrazolyl rings from the ideal C3v symmetry averages only 2.2o, a much smaller twist than has been observed previously in similar complexes. At 150 K the Fe–N bond distances average 1.99 Å, indicative of an almost fully low-spin iron(II) complex; the twist angle is only 1.3o, as expected for a complex with these Fe–N bond distances. The magnetic properties show that the complex undergoes a gradual change from low-spin iron(II) below 85 K to high-spin iron(II) at 400 K. The 4.2 to 60 K Mössbauer spectra correspond to a fully low-spin iron(II) complex but, upon further warming, the iron(II) begins to undergo spin-state relaxation on the Mössbauer time scale such that, at 155 and 315 K, the complex is 7.5 and 65 percent high-spin in the absence of any adjustment for the differing low-spin and high-spin recoil-free fractions. I would replace the previous sentence with the red. I see no reason to give the % from the Mössbauer in the abstract as it is likely a bit low as discussed in detail – neither the mag data nor X-ray data have the recoil issue. The last sentence in the abstract is the key information. OK The 4.2 to 60 K Mössbauer spectra correspond to a fully low-spin-iron(II) complex but, upon further warming above 85 K the iron(II) begins to undergo spin-state relaxation between the low- and high-spin forms on the Mössbauer time scale. At 155 and 315 K the complex exhibits spin-state relaxation rates of 0.36 and 7.38 MHz, respectively, and an Arrhenius plot of the logarithm of the relaxation rate yields an activation energy of 670 ± 40 cm–1 for the spin-state relaxation.

The diversity of the local grapevine varietal set of Tunisia was remarkably noted in areas of Sfax, Kerkhennah, Gabes, Tozeur, Nafta, Degache, Zarzis and Djerba. Some varieties showed requested characteristics at the level of the production quality, its lateness and its fitness to take on tree, and its adaptation to various Tunisian pedoclimatic conditions. In an attempt to explore the genetic diversity of 25 autochthones cultivars of grapevine (Vitis vinifera L.) in South East of Tunisia, the determination of leaves composition on major mineral elements (Na, K, Ca, Mg, Cu, Zn, Fe and Mn) have permitted to appreciate the genetic variability inter-cultivars and its structuring in this collection. Data (PCA plot, cluster analysis) provide that some of these parameters were designed suitable to discriminate significantly few cultivars (ARCz, KORg, BAKz, MGB, BAK, TON, SAKj…). In fact, the recorded differences could be due to sever environmental conditions such as: nature of the soil, culture and climatic conditions, irrigation, salinity, position of leaves on the branches, rootstock etc. [less ▲]

The concentrations of pregnancy-associated glycoproteins (PAG) were determined in buffalo cows (Bubalus bubalis) using three different radioimmunoassay (RIA) systems (RIA-497, RIA-706, and RIA-708). Samples (10 mL) were collected by jugular venipuncture from Week 0 until Week 28 of pregnancy (9 females), and from parturition until Week 10 postpartum (13 females). During pregnancy, PAG molecules were detectable at Week 6 using the three aforementioned RIA systems (3.9 ± 1.3 ng/mL, 9.7 ± 1.3 ng/mL, and 9.9 ± 0.7 ng/mL for RIA-497, RIA-706, and RIA-708, respectively). These concentrations increased gradually until Week 28, reaching values of 39.6 ± 4.0 ng/mL (RIA-497), 50.5 ± 11.9 ng/mL (RIA-706), and 68.2 ± 20.8 ng/mL (RIA-708). PAG concentrations determined by RIA-497, RIA-706, and RIA-708 were strongly correlated throughout the entire gestation period, RIA-708 giving the higher concentrations. At parturition, the mean concentrations ranged from 34.9 ± 4.0 (RIA-497) to 84.7 ± 10.6 ng/mL (RIA-708). Thereafter, the concentrations decreased steadily, reaching very low levels (< 1.0 ng/mL) at Week 8 postpartum. In conclusion, PAG concentrations measured by the above three RIA systems showed a profile similar to those previously described in bovine species, with higher concentrations being detected by RIA-706 and RIA-708. However, the patterns of PAG concentrations, studied using the three aforementioned PAG-RIA systems, differed around parturition, with very low levels being observed in the female buffaloes [less ▲]

Et si le cinéma était d'abord un art chorégraphique ? Depuis toujours, sa préoccupation principale était l'invention de nouveaux agencements de corps et la recherche de nouveaux montages de mouvements. Mais l'idéologie de la mise en scène, venue du théâtre, a rendu cette préoccupation invisible. Pour la rendre à nouveau vivante, c'est toute lhistoire du cinéma qu'il faut relire à l'aune de la chorégraphie : passer du Kino-Glaz (« Ciné-il ») de Vertov à un nouveau Kino-Tanz (« Ciné-Corps » ou « Ciné-Danse »). De Fernand Léger à Michel Gondry, de Georges Méliès à David Lynch, de Pinocchio à Gene Kelly ou de Norman McLaren à Quentin Tarantino, le cinéma n'a jamais cessé de danser. Cest ce que démontre Dick Tomasovic, le plus original des théoriciens du cinéma d'aujourdhui, en onze chapitres qui sont eux-mêmes onze pas de deux, à la fois sidérants et aériens, où s'expérimentent tous les passages de l'idéologie de la mise en scène à l'idéal de la chorégraphie. Il y propose un vocabulaire inouï, bouleversant la manière que nous avions de regarder les films : un vocabulaire qui met au premier plan le rythme et la cadence, le flux et la fluidité, la reprise et la répétition, la mémoire musculaire, la transe et l'extase, le solo et le spectateur, etc. [less ▲]

An extension of a backstepping method for the stabilization of nonlinear systems with respect to a set is presented. Robust control laws providing the system with input-to-output stability are proposed. Possibilities of non-strict Lyapunov functions’ application are discussed. The differences between a conventional backstepping method and an approach proposed in Kolesnikov (Synergetic Control Theory. Energoatomizdat: Moscow, 1994; 344) are analyzed. Performance of the obtained solutions is demonstrated by computer simulation for pendulum with an actuator example. [less ▲]

The European Court of justice has long been aware of economists watching its judgements, particularly in the field of European Competition Law. This article considers first what exactly economists are looking at when they read the case law. Then, the typical content of their observation is analysed. Finally, the analysis turns to how the Court takes into account economist's view point on the case law. [less ▲]

Historians have long acknowledged the importance of the female spectator in actual, staged, tournaments, and literary critics have noted her intrinsic role in the tournaments of romance texts.In both cases, she functions as an inspiration to the male knight performing on the field, and as a means of constructing his masculinity.The potential agency of this female spectator who was able to look down on male bodies from a privileged viewing position has, however, been generally overlooked by art historians.This article uses the tournament context, in which women look at men (and vice versa), as a way of moving beyond the binary oppositions such as masculine/feminine, active/passive, that have traditionally structured discussions of gender and the gaze. By looking in particular at the imagery on carved ivory objects made for women, and their relationship to contemporary literature, I will argue for a more nuanced consideration of the ways women were able to look in the Middle Ages.
