Using existential anthropology in understanding contemporary history I try to reveal the value of the Sartrean model of intentional consciousness in understanding the human relationships and the political conflicts of our time. I examine the cultural aspects of Sartre’s thought. Sartre’s existential anthropology of the historical real-life refers to a complex philosophical method inspired by Husserl’s phenomenology, Freud’s psychoanalysis and Marx’s dialectic. It aims at understanding individual’s imaginary and behavior. Using that method, not only are we able to reveal the structure of people’s intentions in building and defending their personal and national interests, but also can we manifest the imaginary that constitute what Sartre designates by Dog’s mind, that meant criminal’s and racist’s beliefs. Sartre used his method in understanding writers as Baudelaire, Flaubert or Genet, who was also a criminal. Our intention is to apply psycho-analysis in understanding great figures of human history, such as Hitler, the “Dog” of our time, so that we shall be able to built harmless intercultural relationships.

Objectives: To evaluate total salt intake in the adult population through an analysis of sodium in 24-h urine samples in two regions of Belgium. Methods: Urine samples were collected over 24 h from participants and they had to complete a specific questionnaire about salt intake afterwards. Sodium and creatinine concentrations were analysed in these samples. Subjects: The target population comprised adults aged 45–65 years in the region of Ghent and Liege. A total of 123 and 157 volunteers from Ghent and Liege, respectively, were included in the study. Results: The mean creatinine level in Flanders (n=114) amounted to 0.173±0.035 mmol/kg/day, whereas in the Walloon region (n=135) it amounted to 0.161±0.036 mmol/kg/day, after the exclusion of subjects with incomplete urine collection. Intake of sodium in Flanders (n=114) was 4.29±1.29 g/day, whereas in the Walloon region (n=135) it was 3.94±1.44 g/day. In both regions, sodium intake in men was higher than in women. Conclusion: Salt intake was more or less twice as high as the recommended intake. Salt intake as estimated from 24-h urine collections is substantially higher than that previously calculated on the basis of food consumption data. A salt reduction programme for Belgium is primordial. [less ▲]

The IUE low dispersion spectra of the irregular variable V348 Sgr taken close to maximum light were compared with those of the B-type stars HD 53138 and HD 58350 and with those of the extreme helium stars HD 12448 and LS II + 33 deg 005. Energy distribution of V348 Sgr was compared with a theoretical continuous distribution based on UBVRI and uvby photometric measurements close to maximum brightness. Results show that V348 Sgr has a carbon-rich atmosphere and a spectral type between s+B3 and s+B5 in the UV (corresponding to between B3 Ia and B5 Ia in the visible). The object probably belongs to the group of extreme helium stars with an effective temperature of 15,000 to 16,000 K. [less ▲]

We present an analysis of a series of observations of the auroral/polar regions of Jupiter, carried out between September 8 and 11, 1998, making use of the high-resolution spectrometer, CSHELL, on the NASA InfraRed Telescope Facility (IRTF), Mauna Kea, Hawaii; these observations spanned an ``auroral heating event". This analysis combines the measured line intensities and ion velocities with a one-dimensional model of the jovian thermosphere/ionosphere (Grodent et al. 2001). We compute the model line intensities both assuming local thermodynamic equilibrium (LTE) and, relaxing this condition (non-LTE), through detailed balance calculations (Oka et al. 2004), in order to compare with the observations. Taking the model parameters derived, we calculate the changes in heating rate required to account for the modeled temperature profiles that are consistent with the measured line intensities. Comparison of the various heating and cooling terms enables us to investigate the balance of energy inputs into the auroral/polar atmosphere. Increases in Joule heating and ion drag are sufficient to explain the observed heating of the atmosphere; increased particle precipitation makes only a minor heating contribution. But local cooling effects - predominantly H[SUB]3[SUP]+[/SUP][/SUB] radiation-to-space - are shown to be too inefficient to allow the atmosphere to relax back to pre-event thermal conditions. Thus we conclude that this event provides observational, i.e. empirical, evidence that heat must be transported away from the auroral/polar regions by thermally or mechanically driven winds.

This analysis combines the measured line intensities and ion velocities with a one-dimensional model vertical profile of the jovian thermosphere/ionosphere. We compute the model line intensities both assuming local thermodynamic equilibrium (LTE) and, relaxing this condition (non-LTE), through detailed balance calculations, in order to compare with the observations. Taking the model parameters derived, we calculate the changes in heating rate required to account for the modelled temperature profiles that are consistent with the measured line intensities. We compute the electron precipitation rates required to give the modelled ion densities that are consistent with the measured line intensities, and derive the corresponding Pedersen conductivities. We compute the changes in heating due to Joule heating and ion drag derived from the measured ion velocities, and modelled conductivities, making use of ion-neutral coupling coefficients derived from a 3-D global circulation model. Finally, we compute the cooling due to the downward conduction of heat and the radiation-to-space from the H-3(+) molecular ion and hydrocarbons. Comparison of the various heating and cooling terms enables us to investigate the balance of energy inputs into the auroral/polar atmosphere. Increases in Joule heating and ion drag are sufficient to explain the observed heating of the atmosphere; increased particle precipitation makes only a minor heating contribution. But local cooling effects-predominantly radiation-to-space-are shown to be too inefficient to allow the atmosphere to relax back to pre-event thermal conditions.

First-lactation test-day milk, fat, and protein yields from New York, Wisconsin, and California herds from 1990 through 2000 were adjusted additively for age and lactation stage. A random regression model with thirdorder Legendre polynomials for permanent environmental and genetic effects was used. The model included a random effect with the same polynomial regressions for 2 yr of calvings within herd (herd-time effect) to provide herd-specific lactation curves that can change every 2 yr. (Co)variance components were estimated using expectation-maximization REML simultaneously with phenotypic variances that were modeled using a structural variance model. Maximum heritability for test-day milk yield was estimated to be ∼20% around 200 to 250 d in milk; heritabilities were slightly lower for test-day fat and protein yields. Herd-time effects explained 12 to 20% of phenotypic variance and had the greatest impact at start of lactation. Variances of test-day yields increased with time, subclass size, and milking frequency. Test month had limited influence on variance. Variance increased for cows in herds with low and high milk yields and for early and late lactation stages. Repeatabilities of variances observed for a given class of herd, test-day, and milking frequency were 14 to 17% across nested variance subclasses based on lactation stage. [less ▲]

MOTIVATION: The relative abundance of retroviral insertions in a host genome is important in understanding the persistence and pathogenesis of both natural retroviral infections and retroviral gene therapy vectors. It could be estimated from a sample of cells if only the host genomic sites of retroviral insertions could be directly counted. When host genomic DNA is randomly broken via sonication and then amplified, amplicons of varying lengths are produced. The number of unique lengths of amplicons of an insertion site tends to increase according to its abundance, providing a basis for estimating relative abundance. However, as abundance increases amplicons of the same length arise by chance leading to a non-linear relation between the number of unique lengths and relative abundance. The difficulty in calibrating this relation is compounded by sample-specific variations in the relative frequencies of clones of each length. RESULTS: A likelihood function is proposed for the discrete lengths observed in each of a collection of insertion sites and is maximized with a hybrid expectation-maximization algorithm. Patient data illustrate the method and simulations show that relative abundance can be estimated with little bias, but that variation in highly abundant sites can be large. In replicated patient samples, variation exceeds what the model implies-requiring adjustment as in Efron (2004) or using jackknife standard errors. Consequently, it is advantageous to collect replicate samples to strengthen inferences about relative abundance. [less ▲]
