Tungsten(VI) complexes formed in an excess of gluconic acid: A polarimetric and spectrophotometric study

1985

The tungsten(VI)-gluconic acid system in an excess of this organic reagent has been spectroscopically and polarimetrically studied and four species, two mononuclear with stoichiometry 1∶2 (metal∶ligand) and two dinuclear with composition 2∶2, have been identified. The non-formation of a binuclear species with stoichiometry 2∶1 (metal∶ligand) demonstrates some preference towards coordination of carboxylate group.

Hyperon polarization asymmetry: Polarized beams andΩ−production

1985

The parton recombination model relates polarizations in inclusive baryon fragmentation to those of the underlying constituent subprocesses. Measurements of spin-spin correlations in experiments using polarized beams will provide detailed information on the quark spin dynamics in the color-confining recombination process. We present a large number of predictions for the octet baryon\ensuremath{\rightarrow}octet baryon transitions. We discuss the production of polarized ${\ensuremath{\Omega}}^{\mathrm{\ensuremath{-}}}$'s, required to measure the magnetic moment of the ${\ensuremath{\Omega}}^{\mathrm{\ensuremath{-}}}$. We also review the data from unpolarized beam experiments, and find very sa…

Compound Membranes of Linearly Polymerized and Cross-Linked Macrolipids with Phospholipids: Preparation, Microstructure and Applications

1985

Methods for the assembly and for studying the structural and dynamic properties of partially polymerized membranes are described. Mixtures of two classes of polymerizable amphiphiles with diacyl phosphatidylcholines are studied: (1) phosphatidylcholines carrying a diacetylene group per chain (abbreviated as (m,n)-DIINPC (where m + n + 6 equals number of C-Atoms per chain) and (2) a phospholipid-like molecule with a polymerizable methacryl ligand connected to the phosphate head group via (CH2CH2O)m spacers which is abbreviated as (m.n)-POMECY (n = number of C-atoms per chain). — Phase diagrams of the lipid mixtures are established by static light scattering in combination with freeze fractur…

Blockcopolymere aus 2-Isopropenylnaphthalin und Hexamethylcyclotrisiloxan, 7

1985

Anionic polymerization of 2-isopropenylnaphthalene (2-IPN), with butyllithium in THF at −78°C was terminated with ethylene oxide and the resulting terminal alkoxide was used to initiate the polymerization of hexamethylcyclotrisiloxane (D3) at +40°C. This led to the formation of AB-block copolymers which were coupled to ABBA-block copolymers by addition of dichlorodimethylsilane. ABBA-blockcopolymers were obtained with contents of polymethylsiloxane (poly(DMS)) between 77 and 84% of weight and block molecular weights between 1 700 and 27 000 (poly(2-IPN)) and 13 000 and 240 000 (poly(DMS)). Phase separation in polymer films casted from different solvents was studied by electron microscopy an…

119Sn Mössbauer spectroscopic studies of the products of the reaction of triorganotin(IV) derivatives with 6-thiopurine

1985

Abstract A structural study of the products of the reaction of R 3 Sn IV derivatives (R = Me, Bu n , Ph) with 6-thiopurine, 6-TPH 2 , and its sodium salt, 6-TPHNa, has been undertaken using Mossbauer spectroscopy and the point-charge model rationalization of the Mossbauer parameter nuclear quadrupole splitting. The synthetic reactions have been carried out at ca . 0 °C, 20 °C and 50 °C. The Mossbauer spectra of the complexes AlK 3 Sn(6-TPH) are consistent with the occurrence of two distinct tin(IV) sites in samples prepared at the lower temperature, while one only site appears by increasing the temperature of the reaction. Two tin sites constantly occur in the products of the reactions invo…

Frame fungi on insulated windows.

1985

Insulated windows (fixed triple glass window elements), became common in Finland during and after the energy crisis. Moisture tends to condense along the edges causing mold growth on the frames. Nine houses with insulated glass windows and eight with other types of window were studied. Fungus samples were taken from the window edges and from the inside air and cultivated on malt extract agar. In five of the houses with insulated windows there was visible mold growth on the window edges. The predominant fungus was Aureobasidium pullulans. With other types of windows there was only one case of visible mold. The concentrations of fungi were about the same in the air of houses with both types o…

Collision with and avoidance of obstacles by blind cave fish Anoptichthys jordani (Characidae).

1985

Blind Mexican cave fish (Anoptichthys jordani) were released into unknown surroundings and their swimming tracks were recorded. During the first 24 h in a new tank, i.e., in unfamiliar environments, the average swimming velocity of the fish was higher than during the remaining time in the tank. Collision with obstacles was recorded by an electrical contact detection method. Single frame analysis of video-recordings revealed that collision can be correlated with tail movements when the fish is close to an obstacle, whereas avoidance correlates with gliding during approach to an obstacle. These behavior patterns are discussed in the context of the flow field hypothesis and inhibition of the l…

1985

Blood glucose self-monitoring is essential to stabilize diabetes on a normoglycemic level. But often patients do not find the correct insulin adaptation. Therefore, we developed a computerized system which adapts insulin doses using a control matrix. During a first in-patient period we had a remarkable blood glucose normalization and stabilization.

An experimental investigation of the shear behaviour of polyethylenes with different structures

1985

Rheological properties in shear flow are presented for four different polyethylene samples: a high density, a linear low density and two low density polyethylenes manufactured using different techniques. Tests have been performed with the aid of capillary types of instrument equipped with capillaries of various lengths at three different temperatures. End correction factors have been determined and true flow curves obtained. Swelling ratios for both unannealed and annealed samples have been determined as well as the shear rate and shear stress at which irregularities begin. In some cases generalized plots have been prepared and in all cases the rheological response is discussed in terms of …

Reversible esophageal motor dysfunction in botulism

1985

Two cases of botulism with autonomic and neuromuscular system involvement are presented. In both patients, dryness of the mouth and difficulties in swallowing were predominant symptoms. Esophageal manometry revealed a marked decrease in peristaltic amplitude, which was most pronounced in the upper third of the esophagus. These functional abnormalities returned to normal following recovery from the acute disease.

Imunohistochemical Demonstration of Carcinoembryonic Antigen (CEA) in 120 Mammary Carcinomas and its Correlation with Tumor Type, Grading, Staging Pl…

1985

Antisera to CEA were used for the immunohistochemical localization and quantification of this antigen in 120 Bouin-fixed, paraffin embedded mammary carcinomas. These results were compared to tumor type, grading, staging, biochemical receptor status, cytosolic CEA-levels of the same tumors, and preoperative plasma CEA-levels. Mammary carcinomas were usually characterized by a low percentage of CEA-positive tumor cells: 50.9% of the cases contained more than 5% CEA-positive tumor cells and were therefore defined as being CEA-histopositive in this study. A relation could be shown between CEA-histopositivity and the histologic tumor type. The majority of invasive lobular carcinomas, tubular, an…

Numerical simulations and exactly soluble spin-glass models.

1985

Some general arguments based on recent numerical work are presented to explain the different behavior of short-range, random-bond and long-range, random-site spin glasses. We then analyze an exactly soluble spin-glass model, which may be solved without replicas, and show that, except for the absence of microscopic metastable states, its main features are consistent with the long-range picture.

Recent developments in the evaluation of Mössbauer line intensities

1985

The angular dependence of the intensities of pure or mixed multipole transitions is formulated in a new fashion, which takes into account arbitrary texture of the Mossbauer absorber ranging from complete orientation (single crystals) over preferred orientation to random powders and an anisotropic absorption fraction of the nuclei. The application of the theory is demonstrated by means of typical examples from the literature.

Immunoreactivity of monoclonal anti-melanoma antibodies in relation to the amount of radioactive iodine substituted to the antibody molecule.

1985

The damage to monoclonal anti-melanoma antibodies caused by iodination was investigated by comparing the results obtained using the chloramine-T method and the 1,3,4,6-tetrachloro-3 alpha, 6 alpha-diphenyl-glycoluril (IODOGEN) method at different levels of iodine substitution to the molecule. The level of substitution at which losses in immunoreactivity occurred was evaluated in each monoclonal antibody (MAb) studied. This phenomenon was not dependent on the method of substitution, provided that mild conditions of reaction were used. Lineweaver-Burk plots and--in cases of alterations in binding affinity--Scatchard plots were found to provide an adequate description of the binding behaviour …

A numerical simulation scheme for the albedo of city street canyons

1985

A numerical scheme is described for the calculation of effective albedo values of long city street canyons. The method is based on a generalization of the radiation model for inclined surfaces recently presented by Bruhl and Zdunkowski (1983). Calculated albedo values are compared with Aida's (1982) experimentally determined results. It is found that experiment and theory are in reasonable and in some cases in excellent agreement. Additional results obtained by varying the geometry of the street canyon as well as the surface reflectivities are shown to demonstrate the versatility of the calculation scheme.

Nucleoside phosphotransferase in animal tissues. Tissue distribution and kinetic properties

1985

Amphibian, avian and mammal tissues contain a nucleoside phosphotransferase clearly different from those previously described in vegetables and bacteria. Whatever the animal source, the enzyme showed many similar characteristics as far as substrate specificity, dependence upon Mg2+, instability at 37 degrees C, and the protecting effect of nucleotides were concerned. Moreover, when submitted to gel filtration, the enzyme behaved in all cases as a dissociable high molecular weight protein, whose degree of association was controlled by nucleotides. In amphibian and avian tissues multiple forms of the enzyme seem to be present which differ for the substrate concentration at half-maximal veloci…

Implications of the restoration of chiral symmetry in bag model building

1985

We analyze via a bag model description of hadron structure the consequences of having two fundamental scales in QCD, one associated with confinement and the other with chiral-symmetry restration. The main effect is that the exterior pion field becomes weaker and, therefore, we are able to reproduce the axial-vector coupling constant.

1985

The electronic mechanisms of a model hydride transfer reaction are theoretically studied with ab inito RHF and UHF SCF MO procedures at the 4‐31G basis set level and analytical gradient methods. The model system describes the reduction of cyclopropenyl cation to cyclopropene by the oxidation of lithium hydride to lithium cation. The molecular fragments corresponding to the asymptotic reactive channels characterizing the stepwise mechanisms currently discussed in the literature have been characterized. The binding energy between the fragments is estimated within a simple electrostatic approximate scheme. The results show that a hydride‐ion mechanism is a likely pathway for this particular sy…

Interpretation of the SolarCa48/Ca46Abundance Ratio and the Correlated Ca-Ti Isotopic Anomalies in the EK-1-4-1 Inclusion of the Allende Meteorite

1985

$\ensuremath{\beta}$-delayed neutron-emission probabilities of neutron-rich S to K isotopes are calculated with nuclear-structure effects taken into account. These results strongly affect predictions made in high-neutron-density astrophysical scenarios for isotopic abundances of several elements. In particular, it is demonstrated that the solar abundance ratio $^{48}\mathrm{Ca}$/$^{46}\mathrm{Ca}$ as well as the correlated Ca and Ti isotopic anomalies can be explained by the same nucleosynthesis process.

The nucleosomal repeat length of pea (Pisum sativum) chromatin changes during germination

1985

Pea (Pisum sativum) nuclei have been isolated from ungerminated embryos, developing embryonic axes and seedlings. Morphological and biochemical criteria revealed that preparations were free from contaminants and that nuclei were intact. These circumstances permitted an accurate determination of nucleosomal repeat lengths, the values obtained being 175±4 base pairs for ungerminated embryos, 185±5 base pairs for 62-hours germinated embryonic axes and 185±3 base pairs for 6-day old seedlings. The results seem to indicate that the increase in repeat length is associated with the onset of transcription and/or replication of DNA.

Visual evoked potentials in insulin-dependent diabetics

1985

The latency of pattern-reversal VEPs was studied in type I insulin-dependent diabetics without retinal and extraocular involvement. One hundred eyes of 50 diabetics (mean age 19.8 +/- 7.2 years) formed the study group; the duration of the disease ranged between 1 month and 15 years. The latencies of VEPs were progressively delayed in relation to the duration of the disease, becoming more and more evident and stabilizing after about 6 years from the onset of diabetes. The VEP alterations probably indicate alteration of membrane balance or demyelinization.

UROEPITHELIAL DEFENSE IN CHILDREN WITH URINARY TRACT INFECTIONS (UTI)

It is well accepted that obstructive uropathy causes UTI.In patients without urological anomalies a host defense defect of the uroepithelial cells (UEC) may result in increased susceptibility to bacterial infections.Even in patients with vesicourethral reflux (VUR) and recurrent UTI the postulated defense mechanism may be impaired since a significant proportion of these patients still suffer from UTI after surgical therapy.Therefore the influence of UEC on bacterial growth was investigated in 5 groups of children: healthy donors,children with neurogenic bladder due to myelomeningocele (MMC),patients with asymptomatic bacteriuria (ABU;without obstructive uropathy) and patients with VUR after…

Mn3+ in garnets III. Absence of Jahn-Teller distorition in synthetic Mn3+-bearing garnet

1985

The crystal structure of a ternary Mn3+-bearing garnet, close to the composition Gross34 Spess26 CaMnGt40 has been refined to a weighted R-value of 0.051 for 440 unique reflections. The lattice constant is 11.867(1) A, fractional atomic parameters for oxygen are x=0.0374 (2), y=0.0470 (2), and z=0.6532 (2). Refinement of site occupancies gave 0.81 (3) Ca+0.19 (3) Mn2+ in the eight coordinated site 24c and 0.64 (2) Al+0.36 (2) Mn3+ in the octahedral site 16a. No deviation from the cubic space group Ia3d has been observed, the Mn3+-bearing YO6 octahedron is nearly regular. Thus, the presence of the 3d 4-configurated ion Mn3+ does not cause Jahn-Teller distortion in this garnet structure.

Oral Sustained-Release Aminophylline and Bronchodilator Response to Inhaled Fenoterol in Patients with Chronic Airflow Obstruction

1985

The bronchodilator response to inhaled fenoterol (400 micrograms) was examined in the morning and in the afternoon before and during oral sustained-release aminophylline treatment in eight patients with chronic reversible airway obstruction. Bronchodilatation was evaluated by measuring serial peak expiratory flow rates (PEFR) for eight hours after inhaled fenoterol and calculating the area under the time-response curves and the percentage increment from the baseline values. The patients showed an enhancement of the bronchodilatation achieved with fenoterol in the morning during aminophylline treatment. In the afternoon, instead, the effect of the fenoterol was not improved by oral aminophyl…
