Opis:
Five vervet monkeys (Cercopithecus aethiops) and two baboons (Papio doguera) were experimentally infected with Trichinella spirails. The animals were killed two to three months later and larval densities were determined in twelve muscles from each animal. The lowest mean larval densities were found in the diaphragm which averaged 1,807 per g. as compared with more than 3,000 per g. for the biceps, masseter, tiblalis anticus and flexor carpi ulnaris. Although there is a widespread belief that the diaphragm is the most heavily infected muscle in man, this is not confirmed from the limited number of necrepsies reported in the lierature. Further information on the larval densities in the different muscles of man is necessary as a guide to the best sites for biopsy, and to facilitate prevalence surveys based on the examination of material obtained postmortem.

Opis:
The paper relates to the application of microbial enhanced waterflooding to improve the recovery factor and extend the productive life of depleted oil fields in the Carpathians Foreland. This technology and the application method used are categorized as Microbial Enhanced Oil Recovery (MEOR). Results of laboratory tests simulating the microbial flooding process in the oil field are presented along with results from the first two years of microbial flooding at Pławowice oil field. In the first two years of field application this MEOR process has increased the production ratę of two oil wells by 70% on average above the rate before treatment.

Opis:
Background. There are several studies focusing on different issues of innovation, however few of them study the footwear industry. With innovation being a key element for success, and while the Portuguese footwear industry enjoys a period of growth and international recognition (second most expensive in the world) it seems relevant to better understand the engagement of this industry with innovation. Research aims. This paper addresses the issue of innovation in the Portuguese footwear industry. Method. In order to develop this study data from the Community Innovation Survey (CIS) carried out in Portugal during the period 2008 to 2010 was used. CIS is a survey that is carried in most EU countries, and explores company innovation in the product, process, marketing and organization dimensions. Key findings. With the results from this survey, obtained from Statistics Portugal, the different dimensions of innovation were analysed individually and paired. As a main achievement, a lack of an innovative culture was identified. When innovation was identified it was mainly in product and process dimensions. It was also verified that when companies adopt an innovation strategy, it is normally present in more than one dimension

Opis:
Reprocessing of spent nuclear fuel usually employs the solvent extraction technique to recover fissile material, isolate other valuable radionuclides, recover precious metals, and remove contaminants. Effi cient recovery of these species from highly radioactive solutions requires a detailed understanding of reaction conditions and metal speciation that leads to their isolation in pure forms. Due to the complex nature of these systems, identification of ideal reaction conditions for the efficient extraction of specific metals can be challenging. Thus, the development of experimental approaches that have the potential to reduce the number of experiments required to identify ideal conditions are desirable. In this study, a full-factorial experimental design was used to identify the main effects and variable interactions of three chemical parameters on the extraction of protactinium (Pa). Specifi cally we investigated the main effects of the anion concentration (NO3 –, Cl–) extractant concentration, and solution acidity on the overall extraction of protactinium by 2,6-dimethyl-4-heptanol (diisobutylcarbinol; DIBC) from both HCl and HNO3 solutions. Our results indicate that in HCl, the extraction of protactinium was dominated by the solution acidity, while in nitric acid the extraction was strongly effected by the [DIBC]. Based on our results, a mathematical model was derived, that describes the relationship between concentrations of anions, extractant, and solution acidity and the expected values of Pa distribution coefficients in both HCl and HNO3. This study demonstrates the potential to predict the distribution coefficient values, based upon a mathematical model generated by a full-factorial experimental design.

Opis:
This work presents a mathematical model of an aeropendulum system with two sets of motors with propellers and the design and simulation of a loop-shaping h∞control for this system. In this plant, the objective is to control the angular position of the pendulum rod through the torque generated by the thrust of the motorized propellers at the end of the rod’s axis. The control design is obtained by first using feedback linearization and then designing the h∞ controller using the resulting linear system. For the control strategy validation, simulations were conducted in the Matlab/Simulink® environment, and the weighting functions for the h∞ controller were adjusted to obtain the desired performance and stability of the closed-loop system. The simulation results show the efficiency of the applied methodology.
