La Rivoluzione industriale e le origini del diritto del lavoro (XVIII-XX secolo): un percorso didattico di storia sociale per le classi II SCC e III liceo
Creators: name: Bignasca, Vanessa
Publisher: name: Scuola Universitaria della Svizzera Italiana (SUPSI)
Year: 2021

description: Il lavoro si propone di declinare didatticamente la tematica della Rivoluzione industriale e delle sue conseguenze, tra le quali l’esigenza di una legislazione a tutela dei lavoratori e delle lavoratrici. L’approccio di storia sociale, integrante le dimensioni economiche e giuridiche della questione, è declinato in una dimensione geografica a geometria variabile, che dall’Inghilterra porta la propria attenzione alla Svizzera e, infine, al Cantone Ticino. Il percorso segue le trasformazioni sociali generate dalla Rivoluzione industriale, discostandosi tuttavia dalla classica analisi della questione sociale in Inghilterra per privilegiare la storia locale, attraverso l’analisi delle origini della legislazione sul lavoro in Svizzera e delle problematiche legate alla sua applicazione nel Cantone Ticino, attinenti principalmente al lavoro minorile. Il lavoro di analisi critica di fonti primarie, nell’intento di comprendere l’esito dell’applicazione della legge come il risultato di rapporti di forza tra diversi attori in gioco, e la contestualizzazione del lavoro minorile in un sistema di valori diverso da quello attuale, sono concepiti con il doppio obiettivo disciplinare e dell’educazione civica e alla cittadinanza. Tali dimensioni sono rafforzate in una conclusione incentrata sulla riflessione relativa all’attualità del lavoro minorile nel mondo e delle problematiche attinenti alla tutela delle lavoratrici e dei lavoratori in Svizzera.

Galaxy structure from multiple tracers: III. Radial variations in M87's IMF

description: We present the first constraints on stellar mass-to-light ratio gradients in an early-type galaxy (ETG) using multiple dynamical tracer populations to model the dark and luminous mass structure simultaneously. We combine the kinematics of the central starlight, two globular cluster populations and satellite galaxies in a Jeans analysis to obtain new constraints on M87's mass structure, employing a flexible mass model which allows for radial gradients in the stellar mass-to-light ratio. We find that, in the context of our model, a radially declining stellar-mass-to-light ratio is strongly favoured. Modelling the stellar mass-to-light ratio as following a power law, $Υ_{\star} \sim R^{-μ}$, we infer a power-law slope $μ= -0.54 \pm 0.05$; equally, parameterising the stellar-mass-to-light ratio via a central mismatch parameter relative to a Salpeter IMF, $α$, and scale radius $R_M$, we find $α> 1.48$ at $95\%$ confidence and $R_M = 0.35 \pm 0.04$ kpc. We use stellar population modelling of high-resolution 11-band HST photometry to show that such a steep gradient cannot be achieved by variations in only the metallicity, age, dust extinction and star formation history if the stellar initial mass function (IMF) remains spatially constant. On the other hand, the stellar mass-to-light ratio gradient that we find is consistent with an IMF whose inner slope changes such that it is Salpeter-like in the central $\sim 0.5$ kpc and becomes Chabrier-like within the stellar effective radius. This adds to recent evidence that the non-universality of the IMF in ETGs may be confined to their core regions, and points towards a picture in which the stars in these central regions may have formed in fundamentally different physical conditions.

canonical form of the metric

description: The metrics of gravitational and cosmological models are brought into canonical form in comoving coordinates. The FWR curvature parameter is read from this and it is shown that does not correlate to a flat model, but for a spatially positively curved geometry in which exist reference systems which are in free fall. This also corresponds to Einstein's elevator principle. Moreover, we show that our subluminal cosmos is associated with the model of Melia, assuming that is concerned to a free-falling system in the sense described above.

description: We review the evidence for buried ice in the asteroid belt; specifically the questions around the so-called Main Belt Comets (MBCs). We summarise the evidence for water throughout the Solar System, and describe the various methods for detecting it, including remote sensing from ultraviolet to radio wavelengths. We review progress in the first decade of study of MBCs, including observations, modelling of ice survival, and discussion on their origins. We then look at which methods will likely be most effective for further progress, including the key challenge of direct detection of (escaping) water in these bodies.

description: Aged organic aerosol (OA) was measured at a remote coastal site on the island of Crete, Greece during the Finokalia Aerosol Measurement Experiment-2008 (FAME-2008), which was part of the EUCAARI intensive campaign of May 2008. The site at Finokalia is influenced by air masses from different source regions, including long-range transport of pollution from continental Europe. A quadrupole aerosol mass spectrometer (Q-AMS) was employed to measure the size-resolved chemical composition of non-refractory submicron aerosol (NR-PM1), and to estimate the extent of oxidation of the organic aerosol. Factor analysis was used to gain insights into the processes and sources affecting the OA composition. The particles were internally mixed and liquid. The largest fraction of the dry NR-PM1 sampled was ammonium sulfate and ammonium bisulfate, followed by organics and a small amount of nitrate. The variability in OA composition could be explained with two factors of oxygenated organic aerosol (OOA) with differing extents of oxidation but similar volatility. Hydrocarbon-like organic aerosol (HOA) was not detected. There was no statistically significant diurnal variation in the bulk composition of NR-PM1 such as total sulfate or total organic aerosol concentrations. However, the OA composition exhibited statistically significant diurnal variation with more oxidized OA in the afternoon. The organic aerosol was highly oxidized, regardless of the source region. Total OA concentrations also varied little with source region, suggesting that local sources had only a small effect on OA concentrations measured at Finokalia. The aerosol was transported for about one day before arriving at the site, corresponding to an OH exposure of approximately 4×1011 molecules cm−3 s. The constant extent of oxidation suggests that atmospheric aging results in a highly oxidized OA at these OH exposures, regardless of the aerosol source.

description: L’individuo che si esprime con comportamenti pro-sociali si preoccupa del benessere degli altri e della qualità delle relazioni. Tale attitudine evolve con il perfezionamento delle competenze socioemotive quali la capacità d’identificare, conoscere e gestire le emozioni. Nel presente lavoro si analizza l’impatto di un percorso didattico volto a promuovere la conoscenza e la condivisione delle emozioni sullo sviluppo dei comportamenti pro-sociali in una classe di prima elementare. Tale studio è stato incentrato su due aree dell’educazione socio-emotiva: la consapevolezza di sé e la capacità di gestirsi. La raccolta dati è avvenuta attraverso la distribuzione di un questionario che racchiude alcune manifestazioni di queste condotte, consegnato agli allievi sotto forma di autovalutazione e compilato dal docente per la sua valutazione personale. I risultati ottenuti dimostrano un incremento dell’ascolto attivo e dell’adozione di alcuni comportamenti pro-sociali tra gli allievi ed evidenziano i benefici dell’educazione socio-emotiva sulla consapevolezza di sé e delle proprie emozioni, sull’attuazione dei comportamenti pro-sociali e sul clima della classe.

description: Solid-state modulators for pulsed power applications have been a goal since the first fast high-power semiconductor devices became available. Recent improvements in both the speed and peak power capabilities of semiconductor devices developed for the power conditioning and traction industries have led to a new generation of solid-state switched high power modulators with performance rivaling that of hard tube modulators and thyratron switched line-type modulators. These new solid-state devices offer the promise of higher efficiency and longer lifetimes at a time when availability of standard technologies is becoming questionable. A brief discussion of circuit topologies and solid-state devices is followed by examples of modulators currently in use or in test. This presentation is intended to give an overview of the current capabilities of solid-state modulators in various applications.

description: Case farm 7714 was visited by the U.W.-School of Veterinary Medicine, River Falls Support Facility consisting of Dr. Dennis Van Roekel and a team of four students including the main investigator Pat Hady. The farm had been previously investigated about a year earlier (7/29/86) for the main complaint of anestrus in higher producing cows. The goals of that investigation were to evaluate his ration and fine tune it to increase milk production and butterfat. Their findings were that the milking cows were low in energy and they suggested the feeding of higher energy ration which was followed through by increasing the amount of grain fed. They also suggested a different feeding regime should be given to the heifers instead of feeding them the lactating cow grain formula. This was followed through by implementing a different grain ration to each group.

description: We present an algorithm which combines the quantum trajectory approach to open quantum systems with a density-matrix renormalization group scheme for infinite one-dimensional lattice systems. We apply this method to investigate the long-time dynamics in the Bose-Hubbard model with local particle loss starting from a Mott-insulating initial state with one boson per site. While the short-time dynamics can be described even quantitatively by an equation of motion (EOM) approach at the mean-field level, many-body interactions lead to unexpected effects at intermediate and long times: local particle currents far away from the dissipative site start to reverse direction ultimately leading to a metastable state with a total particle current pointing away from the lossy site. An alternative EOM approach based on an effective fermion model shows that the reversal of currents can be understood qualitatively by the creation of holon-doublon pairs at the edge of the region of reduced particle density. The doublons are then able to escape while the holes move towards the dissipative site, a process reminiscent---in a loose sense---of Hawking radiation.

description: Enterprise-wide Optimization (EWO) has become a major goal in the process industries due to the increasing pressures for remaining competitive in the global marketplace. EWO involves optimizing the supply, manufacturing and distribution activities of a company to reduce costs, inventories and environmental impact, and to maximize profits and responsiveness. Major operational items include planning, scheduling, real-time optimization and control. We provide an overview of EWO in terms of a mathematical programming framework. We first provide a brief overview of mathematical programming techniques (mixed-integer linear and nonlinear optimization methods), as well as decomposition methods, stochastic programming and modeling systems. We then address some of the major issues involved in the modeling and solution of these problems. Finally, based on the EWO program at the Center of Advanced Process Decision-making at Carnegie Mellon, we describe several applications to show the potential of this area.

description: A yearling black-baldy steer was presented to the Veterinary Medical Teaching Hospital on August 4, 1986. The owner reported that the steer had been depressed, losing weight, anorexic and not drinking. This steer was one of 220 calves purchased by the owner to be used as Stockers. Of the 220 calves there were four currently sick and five dead. The steer presented was representative of the herd problem. These calves had been on the present location for thirty days and the first calf noticed sick was fourteen days ago. The calves were on a pasture containing mixed bermuda and native grass. Eleven acres of the pasture contained alfalfa with Kochia mixed in. There was also a pasture of millet which the owner reported the calves would not eat. Upon arrival the steer had a temperature of 103.9° F, heart rate 72 and regular and respiratory rate was 24. The steer was thin, weak and had a rough hair coat. The head was swollen and there was excess lacrimal and nasal discharge. The mucous membranes were pale and yellow and mucosal and nasal ulcers were present. The underside of the tongue was ulcerated and necrotic.

description: We present results from the application of a global photometric calibration (GPC) procedure to calibration data from the first 2 years of The Two Micron All Sky Survey (2MASS). The GPC algorithm uses photometry of both primary standards and moderately bright `tracer' stars in 35 2MASS calibration fields. During the first two years of the Survey, each standard was observed on approximately 50 nights, with about 900 individual measurements. Based on the photometry of primary standard stars and secondary tracer stars and under the assumption that the nightly zeropoint drift is linear, GPC ties together all calibration fields and all survey nights simultaneously, producing a globally optimized solution. Calibration solutions for the Northern and Southern hemisphere observatories are found separately, and are tested for global consistency based on common fields near the celestial equator. Several results from the GPC are presented, including establishing candidate secondary standards, monitoring of near-infrared atmospheric extinction coefficients, and verification of global validity of the standards. The solution gives long-term averages of the atmospheric extinction coefficients, A_J=0.096, A_H=0.026, A_{K_s}=0.066 (North) and A_J=0.092, A_H=0.031, A_{K_s}=0.065 (South), with formal error of 0.001. The residuals show small seasonal variations, most likely due to changing atmospheric content of water vapor. Extension of the GPC to approximately 100 field stars in each of the 35 calibration fields yields a catalog of more than two thousand photometric standards ranging from 10th to 14th magnitude, with photometry that is globally consistent to $\sim 1%$.

description: Approximate ripple carry adders (RCAs) and carry lookahead adders (CLAs) are presented which are compared with accurate RCAs and CLAs for performing a 32-bit addition. The accurate and approximate RCAs and CLAs are implemented using a 32/28nm CMOS process. Approximations ranging from 4- to 20-bits are considered for the less significant adder bit positions. The simulation results show that approximate RCAs report reductions in the power-delay product (PDP) ranging from 19.5% to 82% than the accurate RCA for approximation sizes varying from 4- to 20-bits. Also, approximate CLAs report reductions in PDP ranging from 16.7% to 74.2% than the accurate CLA for approximation sizes varying from 4- to 20-bits. On average, for the approximation sizes considered, it is observed that approximate CLAs achieve a 46.5% reduction in PDP compared to the approximate RCAs. Hence, approximate CLAs are preferable over approximate RCAs for the low power implementation of approximate computer arithmetic.

description: For many years the red-hot iron has been the method of choice for the de-horning of calves in the United Kingdom. Nevertheless, there can be little doubt that the method involves considerable tissue destruction and a certain degree of pain in the immediate post-operative period. It is therefore interesting to find that Leister-Ghibli have produced a hot air tool for the same purpose. The Leister-Ghibli hot air tool has a wide variety of applications not only in the field of Veterinary Science but also in Human Medicine, Agriculture and laboratory work. In this study the efficiency of the gun for disbudding calves was investigated.

description: Nanostructures and Nano sized particles has diverted considerable attention among researchers due to their unique properties. Researchers have shown interest in Zinc Oxide as it may be used as a cheap replacement for Si and GaN. Zinc oxide is one of the most promising semiconducting material due to its piezo electric and transparent conducting properties. It has high electrical conductivity and optical transmittance in the visible region and a good absorption in the UV region. Therefore it can be used as window and sunscreen materials. The nanostructured ZnO has normal applications in sensors, transducers, biomedical devices, optoelectronic devices, solar cells etc. The oxidation of high purity Zinc at high temperatures in a muffle furnace yields nanostructures on the surface of metallic Zinc. ZnO particles are synthesized using high energy ball-milling technique. ZnO is widely used due to its large direct band gap of 3.37 eV, a high exciton binding energy at room temperature. The structure and morphology of ZnO Nano structures is analyzed using X- Ray Diffraction method and Scanning Electron Microscope. This paper focuses on the structure and morphology of the furnace melt ZnO Nano particles.

description: High-performance dynamic language implementations make heavy use of speculative optimizations to achieve speeds close to statically compiled languages. These optimizations are typically performed by a just-in-time compiler that generates code under a set of assumptions about the state of the program and its environment. In certain cases, a program may execute code compiled under assumptions that are no longer valid. The implementation must then deoptimize the program on-the-fly; this entails finding semantically equivalent code that does not rely on invalid assumptions, translating program state to that expected by the target code, and transferring control. This paper looks at the interaction between optimization and deoptimization, and shows that reasoning about speculation is surprisingly easy when assumptions are made explicit in the program representation. This insight is demonstrated on a compiler intermediate representation, named \sourir, modeled after the high-level representation for a dynamic language. Traditional compiler optimizations such constant folding, dead code elimination, and function inlining are shown to be correct in the presence of assumptions. Furthermore, the paper establishes the correctness of compiler transformations specific to deoptimization: namely unrestricted deoptimization, predicate hoisting, and assume composition.

description: Recent measurements of the coherent synchrotron radiation (CSR) effects indicated that the observed beam emittance growth and energy modulation are often bigger than previous predictions based on Gaussian longitudinal charge distributions. In this paper, by performing a model study, we show both analytically and numerically that when the longitudinal bunch charge distribution involves concentration of charges in a small fraction of the bunch length, enhancement of the CSR self-interaction beyond the Gaussian prediction may occur. The level of this enhancement is sensitive to the level of the local charge concentration.

description: Current research in Computer Aided Process Design can be classified into three basic tasks: analysis, synthesis and evaluation. This paper reviews improved methods for these tasks from a quantitative perspective. Specifically examples will be given in all three areas on applications of operations research, numerical analysis and mathematical programming to solve chemical process problems. To provide a flavor for this research the paper briefly outlines strategies for flowsheeting and continues with flowsheet optimization. Next process synthesis is introduced and the specific example of heat integration is described. A description of the quantification of process operability for evaluation is given. Finally, some future directions are defined and studies are cited that support these directions.

description: We study the time-evolving currents flowing in an interacting ring-shaped nanostructure after a bias voltage has been switched on. The source-to-drain current exhibits the expected relaxation towards its quasistatic equilibrium value at a rate Γ0 reflecting the lead-induced broadening of the ring states. In contrast, the current circulating within the ring decays with a different rate Γ, which is a rapidly decaying function of the interaction strength and thus can take values orders of magnitude below Γ0. This implies the existence of a regime in which the nanostructure is far from equilibrium even though the transmitted current is already stationary. We discuss experimental setups to observe the long-lived ring transients.

description: Scanning tunneling microscopy (STM) and temperature programmed desorption (TPD) measurements have revealed that the straight step edges of Cu(5 3 3) surfaces are reconstructed by the room temperature adsorption of R-3- methylcyclohexanone (R-3-MCHO). STM and low energy electron diffraction (LEED) investigations have shown that the clean Cu(5 3 3) surface is composed of arrays of narrow (1 1 1) terraces separated by straight (1 0 0) steps. During room temperature adsorption of R-3-MCHO, the (1 0 0) step edges on the Cu(5 3 3) surface reconstruct, adopting a zigzag structure that exposes kinked, high Miller index step edges. The density of step edge and kink adsorption sites on Cu surfaces can be titrated by TPD of R-3-MCHO. TPD experiments also reveal the formation of kinks on the Cu(5 3 3) surface during room temperature adsorption of R-3-MCHO. Furthermore, TPD experiments on the Cu(2 2 1) surface having straight (1 1 0) step edges indicate that these also reconstruct to expose kinked step edges during R-3- MCHO adsorption at room temperature. Although the kinks on such surfaces are chiral, the R- and S-forms appear to be produced in a roughly racemic (equimolar) ratio. Thus, although the reconstruction of the initially achiral Cu surfaces in the presence of a chiral adsorbate could, in principle, lead to a surface with a net chiral structure, R-3- MCHO does not seem to be an effective chiral imprinting agent.
Animal drug use considerations of the bovine practitioner
Creators: name: Washington, George E.
Publisher: name: The Bovine Practitioner

description: The following paper is solely a personal opinion, not official policy of the A.A.B.P. We need to educate the public and especially the press that we have the most wholesome and the least expensive food supply in the world. To be able to accomplish this, I call on the Pharmaceutical Industry, the Center for Veterinary Medicine, all facets of veterinary medicine and animal industries to work together to provide food animal practitioners with new and better products for treatment of their patients so we do not have to use “extra label” treatments. If we do not, we may go back to the time when treatment of choice was whiskey and tender, loving care, but we will not be able to use whiskey, because it will be off label. I hope I have enlightened you to the problems that face the dairy practitioner when it comes to proper drug usage. The “dollar and sense” to the dairy practitioner amounts to the fact that “extra label” is the rule, not the exception when using antibiotics, tranquilizers and anesthetics, because we do not have effective or approved drugs in these groups.

description: In the middle of last century, Bondi and his coworkers proposed an out going boundary condition for the Einstein equations. Based on such boundary condition the authors theoretically solved the puzzle of the existence problem of gravitational wave. Currently many works on gravitational wave source modeling use Bondi's result to do the analysis including the gravitational wave calculation in numerical relativity. Recently more and more observations imply that the Einstein equations should be modified with an nonzero cosmological constant. In this work we use Bondi's original method to treat the Einstein equations with cosmological constant for theoretical curiosity. We find that the gravitational wave does not essentially exist if Bondi's original out going boundary condition is imposed. We find this unphysical result is due to the non-consistency between Bondi's original out going boundary condition and the Einstein equations with cosmological constant. Based on theoretical analysis, we propose an new Bondi-type out going boundary condition for the Einstein equations with cosmological constant. With this new boundary condition, the gravitational wave behavior for the Einstein equations with cosmological constant is similar to the Einstein equations without cosmological constant. In particular, when the cosmological constant goes to zero, the behavior of the Einstein equations without cosmological constant is recovered. Together with gravitational wave, electromagnetic wave is also analyzed. The boundary conditions for electromagnetic wave does not depend on the cosmological constant.

Theory of Non-Equilibirum States Driven by Constant Electromagnetic Fields: Non-Commutative Quantum Mechanics in the Keldysh Formalism

description: We develop a general theory of non-equilibrium states based on the Keldysh formalism, in particular, for charged-particle systems under static uniform electromagnetic fields. The Dyson equation for the uniform stationary state is rewritten in a compact gauge-invariant form by using the Moyal product in the phase space of energy-momentum variables, which originally do not commute in the case of the conventional operator algebra. Expanding the Dyson equation in electromagnetic fields, a systematic method for the order-by-order calculation of linear and non-linear responses from the zeroth-order Green's functions is obtained. In particular, we find that for impurity problems, up to linear order in the electric field, the present approach provides a diagrammatic method for the Stureda formula. This approach also generalizes the semi-classical Boltzmann transport theory to fully quantum-mechanical and/or multi-component systems. In multi-component systems and/or for Hall transport phenomena, however, this quantum Boltzmann transport theory, constructed from the anti-symmetric combination of two different representations for the Dyson equation, does not uniquely specify the non-equilibrium state, but the symmetric combination is required. We demonstate the formalism to calculate longitudinal and Hall electric conductivities in an isotropic single-band electron system in the clean limit. It is found that the results are fully consistent with those obtained by Mott and Ziman in terms of the semi-classical Boltzmann transport theory.

Equivariant Cohomology Of The Chiral de Rham Complex And The Half-Twisted Gauged Sigma Model

description: In this paper, we study the perturbative aspects of the half-twisted variant of Witten's topological A-model coupled to a non-dynamical gauge field with Kahler target space X being a G-manifold. Our main objective is to furnish a purely physical interpretation of the equivariant cohomology of the chiral de Rham complex, recently constructed by Lian and Linshaw in [arXiv:math/0501084], called the "chiral equivariant cohomology". In doing so, one finds that key mathematical results such as the vanishing in the chiral equivariant cohomology of positive weight classes, lend themselves to straightforward physical explanations. In addition, one can also construct topological invariants of X from the correlation functions of the relevant physical operators corresponding to the non-vanishing weight-zero classes. Via the topological invariance of these correlation functions, one can verify, from a purely physical perspective, the mathematical isomorphism between the weight-zero subspace of the chiral equivariant cohomology and the classical equivariant cohomology of X. Last but not least, one can also determine fully, the de Rham cohomology ring of X/G, from the topological chiral ring generated by the local ground operators of the physical model under study.

Cecal dilatation and volvulus
Creators: name: Smith, Donald F.
Publisher: name: The Bovine Practitioner
Year: 1987

description: Dilatation or volvulus of the cecum is the principal differential diagnostic ruleout for cows with an area of tympanitic resonance centered over the right paralumbar fossa. Because passage of digesta between the cecum and the ascending colon is not impeded by the presence of a cecocolic valve or constriction, distention of the cecum invariably results in concurrent dilatation of the proximal loop of the ascending colon (proximal colon) or portions of the spiral or distal loops of the ascending colon. Dilatation of the cecum is a condition of mild severity and may be asymptomatic, with the diagnosis being made during routine examination of the cow for other purposes. The cecum becomes distended with gas and expands into the pelvic inlet with the apex directed caudally. In contrast, volvulus of the cecum is an acute, life-threatening condition characterized by abdominal distention, absence of feces, colic, and death if untreated. In this condition, the cecum and (usually) the first two segments of the proximal colon twist about the mesentery causing incarceration and eventually strangulation obstruction of the affected portions of the bowel. True cecal torsion; that is, twisting of the cecum on its longitudinal axis, is rare. Usually, reports of cecal torsion should be described more accurately as volvulus.

description: In high magnetic field calculations, anisotropic Gaussian type orbital (AGTO) basis functions are capable of reconciling the competing demands of the spherically symmetric Coulombic interaction and cylindrical magnetic ($B$ field) confinement. However, the best available {\it a priori} procedure for composing highly accurate AGTO sets for atoms in a strong $B$ field [Phys.\ Rev. A {\bf 90}, 022504 (2014)] yields very large basis sets. Their size is problematical for use in any calculation with unfavorable computational cost scaling. Here we provide an alternative constructive procedure. It is based upon analysis of the underlying physics of atoms in $B$ fields that allows identification of several principles for the construction of AGTO basis sets. Aided by numerical optimization and parameter fitting, followed by fine tuning of fitting parameters, we devise formulae for generating accurate AGTO basis sets in an arbitrary $B$ field. For the hydrogen iso-electronic sequence, a set depends on $B$ field strength, nuclear charge, and upon orbital quantum numbers. For multi-electron systems, the basis set formulae also include adjustment to account for orbital occupations. Tests of the new basis sets for atoms H through C ($1 \le Z \le 6$), and ions Li$^+$, Be$^+$, and B$^+$, in a wide $B$ field range ($0 \le B \le 2000$ a.u.), show an accuracy better than a few $μ$H for single-electron systems, and a few hundredths to a few mHs for multi-electron atoms. The relative errors are similar for different atoms and ions in a large $B$ field range, from a few to a couple of tens of millionths, thereby confirming rather uniform accuracy across the nuclear charge $Z$ and $B$ field strength values. Residual basis set errors are two to three orders of magnitude smaller than the electronic correlation energies in muti-electron atoms ...

description: We present imaging results from a high Galactic latitude survey designed to examine the structure of the Galactic halo. The objective of the survey is to identify candidate halo stars which can be observed spectroscopically to obtain radial velocities and confirm halo membership. The Washington filter system is used for its ability to distinguish between dwarfs and giants, as well as provide a metallicity indicator. Our most successful imaging run used the BTC camera on the CTIO 4m telescope in April 1999. Photometric conditions during these observations provided superb photometry, with average errors for a star at $M=18.5$ of 0.009, 0.008, 0.011, and 0.009 for $C$, $M$, $DDO51$, and $T2$ respectively. These data are available with the electronic version of this paper, as well as through ADC (http://adc.gsfc.nasa.gov/). We use these data as a template to describe the details of our photometric reduction process. It is designed to perform CCD reductions and stellar photometry automatically during the observation run without the aid of external packages, such as IRAF and IDL. We describe necessary deviations from this procedure for other instruments used in the survey up to June 2000. Preliminary results from spectroscopic observations indicate a 97% efficiency in eliminating normal dwarfs from halo giant candidates for $M<18.5$. Unfortunately, low-metallicity subdwarfs cannot be photometrically distinguished from giants using the Washington filters. These major contaminates unavoidably reduced the overall giant identification efficiency to 66% for $M<18.5$. Our improved knowledge of these stars will increase this efficiency for future spectroscopic observations.
