Superconductivity of Cadmium-Magnesium Alloys

The superconducting transition temperatures, Tc, have been measured for several Cd-Mg compositions. Tc decreases rapidly with increasing Mg content, and is already at 50 at. % Mg less than 30 mK. No relevant change in Tc could be detected as samples were either quenched from above the ordering temperature of an intermediate ordered alloy or annealed below that temperature.
Completely integrable Hamiltonian systems on semidirect sums of Lie algebras

The complete integrability of Hamiltonian systems arising on Lie algebras which have the form of a direct sum is investigated. For algebras in these classes Sadetov's method takes a simpler form: the isomorphism between the algebra arising at the second step of Sadetov's approach and the stationary subalgebra of a generic element can be written out explicitly. The explicit form of this isomorphism is presented, as well as explicit formulae for polynomials in complete systems for the algebras , and . For the algebras the degrees of the resulting polynomial functions are analysed. Bibliography: 15 titles.
Efecto de la extrusión sobre las características físico químicas de harina de quinua (Chenopodium quinoa Willd)

La quinua (Chenopodium quinoa Willd) es un pseudocereal que se produce desde hace muchos anos en las zonas andinas y permite obtener diferentes transformaciones donde se pueden aprovechar todas sus cualidades nutricionales convirtiendola en una alternativa en la agroindustria alimentaria. El objetivo del estudio fue observar los cambios fisico-quimicos en dos variedades de harina de quinua (Tunkahuan y Blanca dulce Jerico) durante el proceso de extrusion y determinar las condiciones (humedad de las harinas, temperatura y velocidad del tornillo) que permitieran obtener un extruido con propiedades funcionales similares a una harina precocida. El indice de absorcion de agua (IAA), indice de solubilidad de agua (ISA) y poder de hinchamiento (PH) fueron las variables de respuesta. La extrusion de las dos harinas a temperatura promedio de extrusion de 105°C, velocidad de tornillo de 150 rpm y humedad de 25 a 30% mejoro las propiedades funcionales (El IAA incremento de 1,81 g gel/g M.S a 4,22 g gel/g M.S en harina extruida de quinua Tunkahuan y de 2,00 g gel/g M.S a 4,27 g gel/g M.S en harina variedad Blanca dulce de Jerico) pero las propiedades nutricionales disminuyeron al igual que la digestibilidad excepto por un incremento del contenido de carbohidratos
The spectroscopy and lasing of monoclinic Tm:KY(WO4)2 crystals

The principal spectroscopic and lasing characteristics of a Tm(15%):KY(WO4)2 crystal were investigated. The transition cross sections, the luminescence quantum yield, and the lifetime and the nonlinear depopulation coefficient of the upper active state were also determined. The slope efficiency of lasing at the 1950 nm wavelength was 45%. The feasibility of tuning in the spectral range 1850 — 1950 nm was demonstrated in principle.
Physiological interpretation of electrical impedance epigastrography measurements

Measurement of the electrical impedance of the gastric region is carried out with the epigastrograph. This generates and applies alternating current around the abdominal area and measures the potential difference in order to determine the impedance externally, via electrodes. The change of epigastric impedance for a subject, given a meal after fasting, depends on the conductivity of the meal compared to the stomach and surrounding tissues. Typically a conductive meal has conductivity >7 mS cm−1, non-conductive <2 mS cm−1 and neutral about 4.5 mS cm−1. Half-emptying times (T50s) from gastric emptying studies in volunteers using three test meals of 450 ml volume were obtained and found to be shorter than expected from the literature. The meals were a 10% glucose solution and two milk shakes of energy 1300 kJ and 2850 kJ, respectively. These electrical impedance epigastrography (EIE) measurements were carried out with scintigraphy. The T50 values of the latter were significantly longer. The direct comparison of the normalized experimental data obtained by both methods led to the concept that EIE measurements are mainly influenced by gastric secretion. Thus the EIE trace of a ‘neutral’ meal suggests the hypothesis that the volume of the meal is not the significant factor but is influenced by gastric acid secretions. Physiology of the gastric mucosa during the digestion of a meal and intragastric pH values also suggests this. Gastric function studies using EIE measurements may therefore reflect gastric ionic concentration rather than the volume of the contents of the stomach. In turn this could lead to the development of a non-invasive method for the continuous recording of gastric acid secretions.
DETERMINING INCLINATIONS OF ACTIVE GALACTIC NUCLEI VIA THEIR NARROW-LINE REGION KINEMATICS. II. CORRELATION WITH OBSERVED PROPERTIES

Active galactic nuclei (AGNs) are axisymmetric systems to first order; their observed properties are likely strong functions of inclination with respect to our line of sight, yet the specific inclinations of all but a few AGNs are generally unknown. By determining the inclinations and geometries of nearby Seyfert galaxies using the kinematics of their narrow-line regions (NLRs) and comparing them with observed properties, we find strong correlations between inclination and total hydrogen column density, infrared color, and Hβ FWHM. These correlations provide evidence that the orientation of AGNs with respect to our line of sight affects how we perceive them beyond the Seyfert 1/2 dichotomy. They can also be used to constrain three-dimensional models of AGN components such as the broad-line region and torus. Additionally, we find weak correlations between AGN luminosity and several modeled NLR parameters, which suggests that the NLR geometry and kinematics are dependent to some degree on the AGN's radiation field.
Effect of Increasing Levels of Corn Bran on Milk Yield and Composition

Thirty-nine lactating Holstein cows (23 multiparous and 16 primiparous) were randomly assigned to 1 of 3 dietary treatments in a crossover design. Dietary treatments differed by the proportion of corn bran [10, 17.5, and 25% dry matter (DM); designated as low, medium, and high] replacing corn silage and alfalfa. The corn bran coproduct contained 8.2% moisture and 12.9% crude protein, 30.4% neutral detergent fiber (NDF), and 45.0% nonfiber carbohydrate, 9.9% ether extract, and 0.70% P (DM basis). The low treatment consisted of 15.8% NDF from forage (fNDF) and 33.1% total NDF; the medium treatment consisted of 12.9% fNDF and 32.5% total NDF; and the high diet contained 9.9% fNDF and 31.8% total NDF. Dry matter intake was not affected by treatment. The percent milk fat decreased by 0.26% with the inclusion of corn bran from 10 to 25% of the diet DM, but total milk fat yield was not affected. In comparison, corn bran increased yield of milk protein 0.12 kg/d when bran increased from 10 to 25% of the diet DM. Total milk yield tended to increase when bran increased from 10 to 25% of the diet DM, but no differences were observed on 3.5% fat-corrected milk. Lastly, feed conversion significantly improved with increasing inclusion: 1.39, 1.39, and 1.55 ± 0.05 kg of milk/kg of DMI for low, medium, and high, respectively. Observed effects were likely due to the increase in energy intake associated with increasing levels of corn bran.
Additions to the Spectra of Highly Ionized Molybdenum, Mo XXIV–Mo XXVIII

We have observed radiation from highly charged molybdenum ions in the JET tokamak plasmas. Spectra were recorded in the wavelength range 70–110 Å, resulting in the classification of 15 new n = 3, Δn = 0 transitions in Mo XXIV–Mo XXVIII.
Quasi-neutral theory of positive columns in electronegative gases

A theory of the positive column in electronegative gases based on fluid-type momentum equations to describe charged particle motion is presented. It is assumed that quasi-neutrality conditions prevail and the ion inertial terms are neglected. The positive ions are assumed to be created by electron collisions with neutral molecules and the negative ions to be formed by dissociative electron attachment and destroyed by detachment in reactions with neutral species. The mathematical formulation consists of a two-point boundary value problem involving two independent parameters, functions of collisional and transport data, and two eigenvalues. One of these is the central ratio of the negative ion density to the electron density, while the other is related to the ionisation-loss balance and embodies a discharge characteristic for the maintenance field. These eigenvalues and the radial density distributions of the charged species were calculated for a wide range of variation of the independent parameters. An application of the theory to a positive column in oxygen is given as an illustrative example.
Cosmological information in the intrinsic alignments of luminous red galaxies

The intrinsic alignments of galaxies are usually regarded as a contaminant to weak gravitational lensing observables. The alignment of Luminous Red Galaxies, detected unambiguously in observations from the Sloan Digital Sky Survey, can be reproduced by the linear tidal alignment model of Catelan, Kamionkowski & Blandford (2001) on large scales. In this work, we explore the cosmological information encoded in the intrinsic alignments of red galaxies. We make forecasts for the ability of current and future spectroscopic surveys to constrain local primordial non-Gaussianity and Baryon Acoustic Oscillations (BAO) in the cross-correlation function of intrinsic alignments and the galaxy density field. For the Baryon Oscillation Spectroscopic Survey, we find that the BAO signal in the intrinsic alignments is marginally significant with a signal-to-noise ratio of 1.8 and 2.2 with the current LOWZ and CMASS samples of galaxies, respectively, and increasing to 2.3 and 2.7 once the survey is completed. For the Dark Energy Spectroscopic Instrument and for a spectroscopic survey following the EUCLID redshift selection function, we find signal-to-noise ratios of 12 and 15, respectively. Local type primordial non-Gaussianity, parametrized by fNL = 10, is only marginally significant in the intrinsic alignments signal with signal-to-noise ratios < 2 for the three surveys considered.
Effects of the acute arginine aspartate supplement on the muscular fatigue in trained volunteers

The physical activity influences specific mechanisms responsible by a reduction in the power production, and consequently on the fatigue. It has been proposed premises to improve the physical performance, and we observed that some studies have been focused on the reduction of the metabolites that decrease the fatigue on intense physical exercising, using aminoacids known for their properties to induce to metabolic changes, and among these, it is the arginine. The present study had the purpose to study the effects of the acute arginine aspartate supplement in trained healthy individuals submitted to an exhaustion protocol on ergonomic bicycle. Twelve 22.6 ± 3.5 years old trained individuals were used in the research. After taking a single dose of arginine aspartate or a placebo solution, they performed three 90 minute test on an ergonomic bicycle to which load increments were added up to reaching the exhaustion. The blood samples were obtained through biochemical analysis, such as: creatinine, urea, glycosis, and lactate. It was found no statistical differences upon the comparison of the Maximal Heart Rate, Maximal Time and Load, and also comparing to the previous and later results on the urea, creatinine and glycosis tests. The lactate concentrations (mmol/l) presented statistical differences compared to the pre-test values (Control: 2.2 ± 0.14; Arginine: 2.43 ± 0.23; Placebo: 2.26 ± 0.11) to the post-test values (Control 10.35 ± 0.57; Arginine: 12.07 ± 0.88; Placebo: 12.2 ± 0.96), p < 0.001. The main results found in this study indicate that the acute administration of the arginine aspartate did not show effective to increase the fatigue tolerance in the individuals evaluated and treated in the incremental test protocol up to the exhaustion. Thus, it can be concluded that the dosage used was not able to increase the muscular fatigue tolerance.
Taxa de absenteísmo da equipe de enfermagem como indicador de gestão de pessoas

Absenteeism in nursing is a difficult problem for health organizations; hence it is an indicator that must be monitored. The objective of this study was to analyze the absenteeism rate of nursing professionals in a public hospital. Absenteeism data were collected monthly, from January to July 2008, and calculated by means of an electronic program. The mean absenteeism index for nurses varied from 5.6% to 9.7% for technicians/nursing aides. Sick leaves were the most prevalent reason for absences. The data revealed the major cause of absenteeism and pointed at the need to change policies for hiring nursing professionals, in addition to reviewing the working processes in order to improve the workers' health conditions.
DISPERSION OF MAGNETIC FIELDS IN MOLECULAR CLOUDS. III.

We apply our technique on the dispersion of magnetic fields in molecular clouds to high spatial resolution Submillimeter Array polarization data obtained for Orion KL in OMC-1, IRAS 16293, and NGC 1333 IRAS 4A. We show how one can take advantage of such high-resolution data to characterize the magnetized turbulence power spectrum in the inertial and dissipation ranges. For Orion KL we determine that in the inertial range the spectrum can be approximately fitted with a power law k−(2.9 ± 0.9) and we report a value of 9.9 mpc for λAD, the high spatial frequency cutoff presumably due to turbulent ambipolar diffusion. For the same parameters we have ∼k−(1.4 ± 0.4) and a tentative value of λAD ≃ 2.2 mpc for NGC 1333 IRAS 4A, and ∼k−(1.8 ± 0.3) with an upper limit of λAD ≲ 1.8 mpc for IRAS 16293. We also discuss the application of the technique to interferometry measurements and the effects of the inherent spatial filtering process on the interpretation of the results.
Variational formulation of the linear MHD stability of 3D plasmas with noninteracting hot electrons

The linear MHD stability problem for 3D plasmas with noninteracting hot electron layers and nested magnetic flux surfaces in the absence of dissipation mechanisms is formulated in variational form. Boozer magnetic coordinates are extended to anisotropic pressure plasmas with nested magnetic flux surfaces for this purpose. A modified energy principle in which the hot electron species current is imperturbable is considered. Plasma incompressibility is imposed and thus a simplified kinetic energy is employed to determine the conditions of marginal stability. The vacuum region surrounding the plasma is treated as a shearless. pressureless and massless pseudoplasma. Fourier decomposition of the perturbations in the periodic angular variables of the magnetic coordinates is applied and a finite element discretization scheme reduces the stability problem to a special block pentadiagonal matrix eigenvalue equation which is amenable to solution with an inverse vector iteration technique. The formulation described is useful to evaluate the linear MHD stability properties of 3D plasma configurations with rigid hot electrons to global internal and external modes.
A new formula for the rotational velocity of magnetically driven arcs

A new, more precise and simple semi-empirical formula has been obtained for the prediction of the rotational velocity of magnetically driven arcs in air and nitrogen. The formula is based on the balance between the motive Lorentz force and the aerodynamic drag force and takes into account changes in the gas density value due to the arc rotation and the axial gas velocity. The formula enables the calculation of the arc velocity in electric arc heaters as a function of current, magnetic field, axial gas velocity and gas density. Experimental results are presented for arcs in air and nitrogen, for currents in the range 100-1760 A, magnetic induction values of 0.005-3.9 T and axial gas velocities of 0.2-33 m s-1. The formula can be useful for the study of cold electrode erosion and engineering calculations of electric arc heaters.

The Addition of Dextrose to the Preparation of Culture Media from Earthworm Juice ( Lumbricus rubellus ) for the Production of Saccharomyces cerevisiae FNCC 3012 Inoculum

Saccharomyces cerevisiae is one of the commonly used yeast for bioethanol production. It can be produced by innoculation in a culture medium containing nitrogen and carbon. Earthworms ( Lumbricus rubellus ) are high in protein and have a relatively low price, which highly potential as source of nitrogen for S. cerevisiae FNCC 3012. The objectives of the study were to compare the growth rate of S. cerevisiae FNCC 3012 on earthworm juice (as natural media) and commercial media. Preparation of earthworm juice was carried out by boiling. Dextrose and sucrose were used as a carbon source. The growth rate of S. cerevisiae FNCC 3012 was measured by optical density (OD) and total reducing sugar (TRS). The results showed that earthworm juice with 1% dextrose addition produced higher yield of S. cerevisiae FNCC 3012 cells than commercial media. The -1 maximum specific growth rate (μ ) and the saturation constant (K ) of dextrose were approximately at 3.4 h and max s -1 3.1 g L , respectively. In conclusion, earthworm juice can be valorised as a medium for production of S. cerevisiae FNCC 3012 inoculum. nitrogen protein sumber nitrogen sebagai sumber S. diperoleh dan total penambahan dekstrosa 1% menghasilkan yield dibandingkan komersial. produksi S.
INVESTIGATION OF ALUMINUM TOXICITY AMONG WORKERS IN ALUMINUM INDUSTRY SECTOR

The study was conducted to evaluate urine aluminum concentration among a total of 150 participants (80 aluminum technicians and 70 nonaluminum technicians as a control). Data were collected through a previously prepared questionnaire which consists of two parts. The first part concerned with demographic data such as age and nationality. The second part concerned with occupational data such as working hours, working years, smoking, and diseases. The mean concentration of aluminum is 51.62+ 29.59 μg/l and the mean concentration of group control 16.32 + 12.49 μg/l. The following variables were associated significantly with aluminum concentration: age, weekly working hours, smoking and daily smoking packets. According to our study, aluminum workers have high concentrations of urine aluminum compared with other studies, in addition to that the incidence of diseases in relation to exposure is low, simply because: 1-Self reported questionnaires may be not a proper way to collect data about diseases. 2Traditional surveillance approaches used in public health practice are difficult to apply to metals poisoning because adverse health effects related to metal exposure may not be clinically diagnosed, except at very high exposure levels, and are not usually listed as reportable diseases. Finally Special safety precautions and educational programs are also needed to limit the aluminum exposure in this industrial group.

Spectroscopic orbits are determined for inner subsystems in nine stellar hierarchies (HIP 2863, 4974, 8353, 28796, 35261, 92929, 115272, 115552, and 117596). Their periods range from 2.5 to 312 days. For each system, estimates of masses, orbital inclination, and other parameters are given.
Catalog of High-velocity Dispersion Compact Clouds in the Central Molecular Zone of Our Galaxy

This study developed an automated identification procedure for compact clouds with broad velocity widths in the spectral-line data cubes of highly crowded regions. The procedure was applied to the CO J = 3 − 2 line data, obtained using the James Clerk Maxwell Telescope, to identify 184 high-velocity dispersion compact clouds (HVDCCs), which are a category of peculiar molecular clouds found in the central molecular zone of our Galaxy. A list of HVDCCs in the area −1. °4 ≤ l ≤ +2. °0, −0. °25 ≤ b ≤ +0. °25 was presented with their physical parameters, CO J = 3 − 2/J = 1 − 0 intensity ratios, and morphological classifications. Consequently, the list provides several intriguing sources that may have been driven by encounters with pointlike massive objects, local energetic events, or cloud-to-cloud collisions.
Dissociative electron attachment to hydrogen

Using two different crossed-beams high-resolution electron attachment instruments (employing either a trochoidal electron monochromator or a hemispherical electron monochromator) we have determined the cross section curve for H- production from H2 via the 4 eV resonance at two different temperatures. These relative partial cross sections have been calibrated by comparing present values for the 14 eV resonance with absolute total cross sections determined previously. Taking into account the experimental energy distribution and the rotational excitation and its influence on the cross section shape we obtain very good agreement with theoretical predictions in terms of both the shape and magnitude of this resonance peak.
