Grauzonen : Funktionsweisen der Beniner Polizei und ihr Verhältnis zur Bevölkerung /// Arbeitspapiere / Institut für Ethnologie und Afrikastudien ; 133

Gewalttätig, korrupt und faul oder eher gesetzestreu, hilfsbereit und freundlich? Diese Abhandlung befasst sich mit der Arbeitsweise der Beniner Polizei und den Bildern, die sie von sich erzeugt und den Eindrücken, die sie bei den Bürgern hinterlässt. Die Arbeit liefert Erkenntnisse über den Aufbau und die Arbeitsweise der Beniner Polizei. Sie verweist auch auf das Konkurrenzverhältnis der Polizei zu anderen Sicherheitskräften, wie etwa der Gendarmerie und sie zeigt, dass sich die Polizeirnin diversen Grauzonen – der Legalität, der Staatlichkeit und der Formalität – bewegt. Informelle Strategien, schleichende Privatisierung und Korruption sichern in einem gewissen Rahmen das Funktionieren der Institution. Diese Schwächen der Institution haben jedoch negative Auswirkungen auf das Bild der Polizei und ihr Verhältnis zu den Bürgern. Nicht das propagierte Ideal einer Polizei, sondern die realen Interaktionen mit ihr dominieren die Wahrnehmung der Bürger von der Organisation.

Discarge compilation from The Global River Discharge (RivDIS) Project

The Global River Discharge (RivDIS) data set contains monthly discharge measurements for 1018 stations located throughout the world. The period of record varies widely from station to station, with a mean of 21.5 years. These data were digitized from published UNESCO archives by Charles Voromarty, Balaze Fekete, and B.A. Tucker of the Complex Systems Research Center (CSRC) at the University of New Hampshire. River discharge is typically measured through the use of a rating curve that relates local water level height to discharge. This rating curve is used to estimate discharge from the observed water level. The rating curves are periodically rechecked and recalibrated through on-site measurement of discharge and river stage.

Effects Of High Pressure Homogenization On The Activity, Stability, Kinetics And Three-dimensional Conformation Of A Glucose Oxidase Produced By Aspergillus Niger.

High pressure homogenization (HPH) is a non-thermal method, which has been employed to change the activity and stability of biotechnologically relevant enzymes. This work investigated how HPH affects the structural and functional characteristics of a glucose oxidase (GO) from Aspergillus niger. The enzyme was homogenized at 75 and 150 MPa and the effects were evaluated with respect to the enzyme activity, stability, kinetic parameters and molecular structure. The enzyme showed a pH-dependent response to the HPH treatment, with reduction or maintenance of activity at pH 4.5-6.0 and a remarkable activity increase (30-300%) at pH 6.5 in all tested temperatures (15, 50 and 75°C). The enzyme thermal tolerance was reduced due to HPH treatment and the storage for 24 h at high temperatures (50 and 75°C) also caused a reduction of activity. Interestingly, at lower temperatures (15°C) the activity levels were slightly higher than that observed for native enzyme or at least maintained. These effects of HPH treatment on function and stability of GO were further investigated by spectroscopic methods. Both fluorescence and circular dichroism revealed conformational changes in the molecular structure of the enzyme that might be associated with the distinct functional and stability behavior of GO.

Adsorption of amyloglucosidase from Aspergillus niger NRRL 3122 using ion exchange resin

Amyloglucosidase enzyme was produced by Aspergillus niger NRRL 3122 from solid-state fermentation, using deffated rice bran as substrate. The effects of process parameters (pH, temperature) in the equilibrium partition coefficient for the system amyloglucosidase - resin DEAE-cellulose were investigated, aiming at obtaining the optimum conditions for a subsequent purification process. The highest partition coefficients were obtained using 0.025M Tris-HCl buffer, pH 8.0 and 25ºC. The conditions that supplied the highest partition coefficient were specified, the isotherm that better described the amyloglucosidase process of adsorption obtained. It was observed that the adsorption could be well described by Langmuir equation and the values of Qm and Kd estimated at 133.0 U mL-1 and 15.4 U mL-1, respectively. From the adjustment of the kinetic curves using the fourth-order Runge-Kutta algorithm, the adsorption (k1) and desorption (k2) constants were obtained through optimization by the least square procedure, and the values calculated were 2.4x10-3 mL U-1 min-1 for k1 and 0.037 min-1 for k2 .
