Computerized offender assessment: Validation study.

Evaluated the validity of a computer-based test interpretation (CBTI) system for mental health screening in correctional settings. First, 100 adult male felons were administered a brief mental status interview and a series of psychological tests, including the Minnesota Multiphasic Personality Inventory (MMPI), the revised Beta IQ Examination, and the Buss-Durkee Hostility Inventory. Psychiatric diagnoses and CBTI ratings of victimization, violence, suicide, and substance abuse potentials were compared with clinicians' evaluations. Second, CBTI diagnoses of 109 inmates were compared with Diagnostic Interview Schedule (DIS) diagnoses. Last, CBTI risk ratings were compared with institutional infraction records of 1,718 inmates. Agreement with CBTI and clinicians' risk ratings was fair. CBTI agreement with clinicians' and DIS diagnoses ranged from 60–93%. Ways of improving CBTI algorithms and the value of this approach in correctional screening are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effect of water content on thermal and dynamic mechanical properties of xanthan powder: A comparison between standard and novel techniques

In this work, the sorption isotherms of xanthan powder obtained under static and dynamic conditions and their fitting with mathematical models were discussed. The transitions within xanthan-water systems have been investigated using a standard material characterization technique - Differential Scanning Calorimetry (DSC) - and two novel techniques - Dynamic Mechanical Thermal Analysis (DMTA) material pocket and Phase Transition Analysis (PTA). It was found that within water-xanthan systems, the onset temperature for the melting of freezable water obtained from DSC method was in agreement with freezable water melting peaks obtained via DMTA material pocket at levels of hydration when the freezable water was present. Also, low-temperature transitions, related to polysaccharide-water interactions, were observed by both techniques within xanthan systems which contained no freezable water. However, the use of the PTA technique was limited to xanthan systems with low water content.

The compatibility of the polystyrene/acrylonitrile-butadiene-styrene grafted copolymer system

Summary The study of polystyrene (PS)/acrylonitrile-butadiene-styrene (ABS) grafted copolymer/cyclohexanone or methylene chloride system compatibility both in concentrated solutions and solid state has been carried out by phase separation, viscosimetrical measurements and thermal behaviour.Having in view the obtained data it has been ascertained that the systems present different degrees of compatibility depending on the mixtures composition. At higher temperatures, the compatibility of the components is changed.     

Fluorescent guanosine-nucleotide analogs suitable for photoaffinity-labeling experiments

The synthesis and properties of strongly fluorescent derivative of inosine and its nucleotides are described. Reaction of 2-chloro-inosinic acid with sodium azide leads to a product bearing the tetrazole ring between position 2 and 3. Methylation at N1 was effected with dimethyl sulfate. The corresponding nucleosides and their 5'-triphosphates were also prepared. Only the non-methylated series is at equilibrium with small concentrations of their azido forms, and can be photolyzed by wavelengths above 300 nm. Both series are strongly fluorescent, their emission and excitation fluorescence spectra, as well as their quantum yields were measured. The nucleoside 5'-triphosphates are able to initiate and sustain polymerization of porcine brain tubulin.     

Study of the compatibility in the poly (vinyl-chloride) -poly (vinyl-alcohol) system

Summary Although poly (vinyl-chloride) — PVC — and poly (vinyl-alcohol) — PVA —mixtures are used in practice for coatings, containers, fibers, few studies are encounterd concerning their compatibility (7, 8).This paper establishes both the optimum compatibility ratio and the thermal behaviour of the mixtures.The compatibility study in solid state was realised using the methodes: optical microscopy, thermogravimetry, DSC, inverse gaschromatography and IR spectroscopy.
