Es geht um die Bedeutung der auf weite Lebensbereiche expandierten Animation als sozialer Kontrolle. Die ursprünglich nur in der Urlaubsgestaltung kurzfristig angewandte Animation weitet sich zu langfristig intendierter Beeinflussung der Gestaltung von Wohn- und Lebensverhältnissen aus durch die Vorgabe architektonischer Strukturen und sozialer Verhaltensmuster durch Sozialarbeiter- und bevölkerungsnahe Polizeitätigkeit. Sie ist dem Taylorismus, der die Beeinflussung und Kontrolle des Arbeitsverhaltens fordert, vergleichbar. Das Ziel der Animation besteht in sozialkultureller Aufbauarbeit, die die Kreativität und Selbstentfaltung des einzelnen in durch Selbstkontrolle geregeltem sozialem Handlungsfeld sichert, was gleichzeitig die Einschränkung persönlicher Freiheit durch die vorgegebenen, erwünschten Verhaltens- und Handlungsmuster bedeutet.

The electronic absorption spectrum of the van der Waals dimer Hg2 has been measured in the UV–spectral range by a new supersonic jet direct absorption technique. The data led to an improved analysis of the X 10+g–G 10+u transition, yielding the parameters ω'e =79 cm−1, ωex'e =0.22 cm−1, and Re =3.00 A(ring) for the Morse potential of the G 10+u state.

An apparatus has been constructed to produce metal compounds using laser ablation and to investigate their rotational spectra with a microwave Fourier transform (MWFT) cavity spectrometer. The first three such compounds that have been studied are silver chloride, aluminum (I) chloride, and copper (I) chloride, produced by ablation of silver, aluminum, and copper rods in the presence of chlorine gas, using a Q-switched Nd:YAG laser (532 nm). The high resolution and sensitivity available with the MWFT cavity spectrometer have permitted the first determination of nuclear spin–rotation coupling constants for AlCl and CuCl. These constants have been used to examine the electronic structures of the molecules. Values of the rotational and nuclear quadrupole coupling constants have also been improved for the three metal chlorides.

Under routine source conditions, the optimum nozzle-skimmer distance to achieve maximum molecular beam intensities is within the range of a few millimeters. In cases where double skimming is additionally required, the distance between the skimmers should be kept small in order to sample a sufficiently large solid angle of the beam and hence maintain a good enough intensity. These two facts make it normally difficult to isolate the first from the second expansion chamber using a commercial vacuum gate valve due to the lack of remaining space. This note presents the design of a vacuum-tight valve which allows the aperture of a skimmer to be closed by plugging a needle directly against its internal conical wall. The valve can be driven manually or pneumatically from outside the vacuum chamber. The helium conductance of the valve was measured to be better than 1×10−8 mbar×l×s−1 for a helium partial pressure difference of 1 bar. © 1997 American Institute of Physics.

Head lice is the most frequently occurring communicable disease, except for the common cold, among children in the United States. The impact on a family facing the challenge of head lice is tremendous, ranging from emotional to financial distress. Challenges also face the health care provider and school personnel. Many over-the-counter preparations and prescription products are available to combat head lice. With the alleged advent of pediculicide-resistant head lice, many other products and applications not necessarily intended to treat head lice are being recommended. The purpose of this article is to outline the products and procedures currently being utilized and to provide a starting point for treating head lice.

A system of nanometer sized cobalt clusters surrounded by dielectric shells has been investigated by electrical dc conductivity measurements. The cobalt clusters have a diameter of 36 A(ring) and are surrounded by an approximately 12-A(ring)-thick layer of tetra-octyl-ammonium bromide surfactant molecules and poly(phenyl-p-phenylenevinylene). The conductivity σ shows a temperature dependence ln(σ)∝(T0/T)1/2 in the range 100〈T〈240 K. At T(approximately-greater-than)240 K, the temperature dependence of the conductivity demonstrates some peculiarities. Differential scanning analysis suggests that at 240〈T〈350 K phase transitions of the composite material take place. The observed temperature dependence of the conductivity σ for T〈240 K is typical for hopping conduction in granular metallic systems. A theoretical analysis shows that the data are consistent with a hopping model in which the separation between grains is a random variable uncorrelated with the activation energy. The observed nonlinear dependence of the conductivity on the electric field F is interpreted in the framework of the concept of the effective temperature, which suggests that the influence of T and F on σ can be parameterized by a single quantity Teff(T,F). Comparison between the theoretical results and experimental data provides a suitable expression for Teff(T,F). © 1995 American Institute of Physics.

Thin films of YBa2Cu3O7−x have been prepared epitaxially on 〈100〉 SrTiO3 by laser evaporation in a single-step process. The resistivity of the films decreases linearly with temperature and is measured to 80 μΩ cm at 100 K. The samples are completely superconducting at 88 K. The critical current densities are as high as 5×106 A/cm2 at 77 K in strip lines of 8 μm width. Irradiation with 25 MeV 16O ions at 77 K combined with in situ measurements was applied to study the influence of lattice disorder on superconducting properties. The resistivity ρ increases, whereas the critical superconducting temperature Tc0 and the critical current density jc in the absence of a magnetic field decrease proportionally to the ion fluence. Contrary to this behavior, we observe an enhancement of jc in magnetic fields larger than 1 T. The maximum enhancement is about a factor of 2 at a fluence of 1014 16O/cm2. This increase is due to pinning at irradiation-induced pinning centers. Simultaneously the upper critical magnetic field Bc2 (T) exhibits an increasing positive curvature leading to a crossover with Bc2(T) of the unirradiated samples.

We report the fabrication of epitaxial CoSi2 layers on Si(111) as thin as 1 nm. The crystalline lattice of these layers is coherent with the Si lattice, and the silicide is electrically continuous. There are pronounced structural differences between films which are less than 3 nm thick and those which are thicker. The resistivity of the layers increases sharply with decreasing thickness. This is the first report of the growth of coherent, electrically continuous CoSi2 layers on Si.

The formation of TiSi2 thin films on Si has been investigated by in situ x-ray diffraction and electrical transport. The x-ray results show unequivocally that the staging proceeds through two orthorhombic polytypes of TiSi2 according to the sequence: sputter-deposited metallic Ti or TiSix alloy films on Si(001)→TiSi2 (C49 structure)→TiSi2 (C54 structure), with no evidence of lower silicides. Electrical transport shows metallic behavior for all phases and distinctive features in the annealing curves which correlate with the structural transformations. Most important, the resistivity, characteristically very high for the C49 phase, undergoes a precipitous drop at the C49→C54 transition. In the C54 phase when fully annealed the resistivity is 12.4 μΩ cm at room temperature and 0.66 μΩ cm at 4.2 K.

Interleukin-8 (IL-8), a 72 amino acid peptide secreted by cells of the immune system and of the amnion, chorion and decidua, was measured in women in late pregnancy. IL-8 was detected in the urine of 91 of 104 women with premature rupture of the fetal membranes, with values exceeding 1000 ng/L in cases of severe intra-amniotic infection. Women with urinary tract infections were excluded. The routine measurement of IL-8 in urine, together with C-reactive protein in serum, thus provides a low risk and technically simple approach to the assessment of intra-amniotic infection.

In order to acquire real-time transient alkali data on coal-derived gaseous fuel and combustion streams often at low ppb levels, an extractive, total (vapor and particle-bound) sodium and potassium monitor has been designed, constructed, and tested. This fiber-optic alkali monitor (FOAM) utilizes state-of-the-art fiber-optic light transfer, a novel light-filtering background correction method, and high sensitivity photodiode signal detection. The sample enters the monitor's high-temperature flame, which supplies energy to both decompose and excite the sample. The flame then emits light at the characteristic wavelengths of sodium and potassium. The resulting emissions are transferred by the fiber-optic bundle to the detection system, where the signal is filtered, background corrected, and transferred to the data system. The FOAM has advantages over previous instrumentation in being rugged, portable, and compact. Laboratory testing of the FOAM has been completed. The FOAM was determined to be highly sensitive (mid-ppt detection limits) with a wide linear dynamic range (four orders of magnitude). The results of field monitoring of alkali levels in the exhaust stream of a pressurized combustor using the FOAM indicated that the monitor was capable of real-time, fast tracking of transient alkali behavior in a high-temperature/high-pressure process stream.

Paired estimations of serum heat stable alkline phosphatase (HSAP) concentration and urinary oestrogen output were perormed on 100 patients (544 estimatons). There was no correlation between these values.There was a weak correlation between urinary oestrogen output and fetal weight. The HSAP content of 47 placentae was assayed and compared with the last serum HSAP level before delivery. There was a weak correlation between these parameters.

This paper examines the role of cost efficiencies on efficient management of branch networks in the contemporary European commercial banking industry. The analysis, which could be generalised to other industries, indicates that larger banks are more likely to have heavily utilised branch networks than smaller banks and to exhibit fewer cost efficiencies from building more branches. The finding of this result within each country suggests the role of internal firm size regardless of competitive conditions. The similar cross-country finding suggests the impact of factors such as market structure/concentration levels and type of non-price competition. Larger banks can generate less income per unit asset deployed. Cross-border efficiency might be improved by greater use of banks with under-used networks by banks with over-used networks.

Experiments to generate a thin composite Fe-Ag film employing a sputter-gas-aggregation process are described. The magnetic properties are studied at low temperatures. In addition, the morphology is determined by high-resolution transmission electron microscopy and the structure by using x-ray diffraction and XAFS. Small clusters of about 11 A(ring) in diameter are highly dispersed in an Ag matrix. They show the characteristics of interacting superparamagnets. © 1995 American Institute of Physics.

In 1984, the Illinois Department of Energy and Natural Resources was required to assess the regulations and practices of the Illinois Underground Injection Control (UIC) program as it relates to Class I hazardous waste disposal wells. Nine injection wells, including two standbys (one inactive), are currently in operation at seven sites in the state. These wells range in depth from 1540 to 5524 feet (470 to 1683m; most inject wastes into porous carbonate formations (two wells inject into a thick sandstone). In 1984, approximately 300 million gallons (1.1 billion liters) of industrial wastes were disposed of in these wells. Acids were the most common waste disposed of, although water made up 70 to 95 percent of the wastes by volume. Illinois has been granted primacy in operating this program.The geologic environment, consisting of the unit accepting the waste and confining units lying above and below, has the capacity to accept the waste, to retain it, and to protect all underground sources of drinking water (USDW) from contamination by its injection. The geology of Illinois is relatively simple and includes disposal zones and associated confining units suitable for deep-well injection across the central two-thirds of the state.The regulatory structure for Class I injection wells is generally adequate in concept and scope to ensure containment of injected wastes and to safeguard underground sources of drinking water in Illinois. There is a need to update and strengthen selected portions of the regulatory practices in the areas of waste sampling protocol, chemical analysis of collected waste samples, and evaluation of injection well testing and monitoring data.A number of technologies exist that can treat and dispose of most hazardous and non-hazardous waste streams. Each of these technologies has associated with it economic, environmental and societal impacts.
