Nutzung des Zentrifugalkraftfeldes für die Vorhersage der Langzeitstabilität von kosmetischen Emulsionen

Die Bestimmung der Haltbarkeitsdauer kosmetischer Emulsionen ist von grosem industriellen Interesse. Bisherige Verfahren zur Bestimmung der Stabilitat von Emulsionen sind nur sehr bedingt auf langzeitstabile Emulsionen anwendbar. In dieser Arbeit wurde erstmals eine optische Zentrifuge zur Vorhersage der Langzeitstabilitat von kosmetischen Emulsionen eingesetzt. Diese Methode erfordert keine Wiederholungsmessungen und wurde sowohl auf W/O- als auch auf O/W-Emulsionen angewandt.
The Applicability of Machine Learning Concepts to Game Artificial Intelligence

The purpose of this study is to examine the applicability of machine learning concepts to general game playing. Results were compared against a Monte Carlo Tree Search player using a propositional network to represent game states. Linear regression proved to be effective at determining which state propositions, if any, contributed directly towards higher utility for the player, and in games where such propositions did exist the hypothesis function derived by the linear regression method was effective. Conversely, the hypothesis function performed especially poorly in the cases where what constituted a more advantageous state was more complex, particularly in cases where the goal was more directly correlated with the number of turns played in the game than with specific propositions more directly in the player’s control.
Management to mitigate and adapt to climate change

Management decisions both at the field and off-site have the potential to contribute to climate change mitigation and adaptation. Climate change threatens to increase the potential for soil erosion, reduce soil quality, lower agricultural productivity and negatively impact food security and global sustainability, making it one of the most severe challenges we will face in the 21st century. This paper looks at the potential of management to help us, not only mitigate climate change, but also to help us adapt to a changing climate. Different aspects of carbon management, nitrogen management, manure management, management in low-input systems (sustainable agriculture), and grazing land management are discussed as examples. Management decisions regarding conservation practices, such as no-till, conservation agriculture, and returning crop residue to the field to increase nutrient cycling, can contribute to carbon sequestration and help us mitigate and adapt to climate change. Additionally, management of grasslands, restoration of degraded/desertified lands, nitrogen management to reduce greenhouse gas emissions, precision conservation management at a field and/or watershed level, and other management alternatives can also help us mitigate and/or adapt to climate change. Management for climate change mitigation and adaptation is key for environmental conservation, sustainability of cropping systems, soil and water quality, and food security. This paper suggests, based on a review of the literature, that management decisions that reduce soil erosion, increase carbon sequestration to improve soil functions, soil quality, and soil health, and contribute to the resilience of soils and cropping systems will be needed to respond to climate change and related challenges such as food security. Our review suggests that without management decisions that increase soil and water conservation, food security for the world's growing population will be harder to achieve.
FROM THE EDITOR-IN-CHIEF Welcome , all , to the 2 nd Issue

Although surgeons may perceive that evidence-based medicine mandates a strict adherence to randomized trials, it more accurately involves informed and effective use of all types of evidence (from meta-analysis of randomized trials to individual case series and case reports), with particular emphasis on evidence from the medical and surgical literature, in patient care. With the escalating amount of available information, surgeons must consider a shift in paradigm from traditional practice to one that involves question formulation, validity assessment of available studies and appropriate application of research evidence to individual patients. Surgical investigators must endeavor to conduct methodologically rigorous trials, whenever possible, and be explicit and transparent in their reporting of methods and data. Herein, an overview of the issues involved in the design and conduct of surgical trials with an emphasis on randomization, concealment of allocation, blinding, type I and II errors and intention to treat analysis, is provided.

Safety Program Support Outcomes

When applied to safety, errors in risk perceptions posed by a specific hazard may lead to disagreements among project team members, misallocation of resources and, in worst cases, incidents. In OSH, one goal is to achieve the proper recognition and evaluation of safety hazards and the risks they pose. To illustrate risk perception management in safety, this article reviews perceptions of hazards and associated controls based on the principle: risk = hazard/ control. The four basic expected scenarios and reactions are: 1) Low hazard/high control: Annoyance, low support of safety program; 2) Low hazard/low control: Compliance/neutral; 3) High hazard/low control: Fear, outrage with a lack of safety support; 4) High hazard/high control: Support of safety program. The article discusses achieving a correct, shared vision of project hazards and required controls within project teams as a necessary condition of an effective OSH program. Differences in Risk Perceptions Risk perception is related to conceptions of knowledge that stress the limits of science (Sjöberg, Moen & Rundmo, 2004). Recognition and evaluation (perception) of hazards as well as evaluation (perception) of controls have elements of subjectivity. People respond to hazards according to their perceptions of the risks those hazards pose. What they perceive, why they perceive it that way and how they will subsequently behave are matters of great importance to industries and governments trying to assess and implement new technologies (Peters & Slovic, 1996). People’s perceptions of risks posed by a specific hazard vary based on their personalities, experience, knowledge and many other criteria, and these perceptions vary among individuals and groups as well. Subjective risk perceptions are analyzed and studied with a classification strategy: psychometric paradigm. Surveys, for example, may be asking responders to provide a numerical value (e.g., from 1 to 7) to characterize a risk posed by some specified elements of a particular hazard (Fischhoff, Slovic, Lichtenstein, et al., 1978) such as: •voluntary versus nonvoluntary exposure (e.g., smoking vs. nuclear power station exposure); •chronic versus catastrophic outcome (e.g., exposure to X-rays vs. fall from height); •common versus dread (e.g., caffeine vs. nuclear power plant incident or fall from height); Vladimir Ivensky, CSP, CIH, has more than 25 years’ experience in OSH.

AAR An Audio Augmented Reality System

As we hear sound in three dimensions the reproduction of spatial aspects of audio is essential to digitally create, recreate or enhance an environment. Only recently has computer processing power reached levels enabling performance of synthesis and reproduction of 3D soundscapes in real-time, also on inexpensive hardware. An implementation of a real-time spatial audio rendering system for augmentation of real life situations, and an exa mination of some of the possibilities such a system provides, is the goal of this thesis. Providing intuitive access to an increasing amount of information in everyday environments is a great challenge. Augmented reality systems address this issue but have so far mainly focused on visual enhancements, which usually require rather immoderate means in terms of perceptual effort. There exist surprisingly few attempts of utilising audio user interfaces in real life environments. The major aim of this thesis has been to implement a low cost audio augmented reality prototype system and to implement and explore some applications. The result is the AAR system, providing a full framework to design and create spatial audio applications. Using the AAR system, three test applications have been implemented were a museum tour guide turned out especially well. The three major components of the system are the listener, the emitters and their environment. In an application a listener moves around free in space where different locations, such as physical rooms or parts of rooms, provide boundaries between different acoustic landscapes. Audio objects, the emitters, are placed within these environments and can be made to interact with the listener based on his location. The system is implemented using a client-server architecture and the rendering of the 3D audio and of the environmental acoustics is done through the DirectSound3D and the EAX API’s. A head-tracking device makes it possible to use head related transfer functions. An interface to a graphical soundscape design tool is also included. In evaluating the system a brief comparison with a sophisticated audio rendering system, as well as the implemented test applications, showed a satisfying quality of the produced spatial sound.

Type A lmmunoglobulin Deficiency Presenting as a Mixed Polymicrobial Brain Abscess : Case Report

OBIECTIVE AND IMPORTANCE: We pr€sent a case report of a patient wilh a left frontal brain abccess. Cultures obtained fiom the abecess at lhe time of suqgery were idenlified as dental flora knovm to establish a synergistic relationslrip in polymicrobial infections. Ihis type of synergistic relalionship nukes the clearance of an infeclion more difficult for an intact immune sydem. A serum immunoglobulin (lg) Type A deficiency was identified postoperatively, This immunodeficiency may have contrihrted to 0re development of the absces. CtlNlCAt PRESENTATION: The patient presented with headaches and photophobia. Computed tomography of the head performed with intravenously administered contrast demonstrated a left frontal brain abscess. INTERVENTION: The patient was operated on through a left frontal approach, carefully avoiding the frontal sinus. The abscess was aspirated, and the patient was treated with intravenous antibiotics for several weeks. Postoperatively, the patient did well. There were no signs of enhancement on follow-up computed tomographic scans at 7 and 12 months postoperalively. CONCLUSION: Through a comprehensive immunological workup, an lgA deficiency was identified postoperatively. Although the deficiency of a single type of lg may b€ asymptomatic/ complications from recurrent or chronic bacterial infections may occur. The deficiency of lgA. combined with a synergistic polymicrobial infection, contributed to the developmenl of an intracranial abscess. A patient presenting with a brain abscess without any predisposing medical history should be evaluated for an underf ying immune deficiency. (Neurosurgery 44:41 1 -41 4, 1 999)
Desempenho de OpenStack e OpenNebula em Estações de Trabalho: Uma Avaliação com Microbenchmarks e NPB

IaaS (Infrastructure as a Service) clouds provide on-demand computing resources (i.e, memory, networking, storage and processing unit) for running applications. Studies that evaluate the IaaS cloud performance are limited to the virtualization layer and ignore the impact of management tools analysis. In contrast, our research investigates the impact of them in order to identify if there are influences or differences between OpenStack and OpenNebula. We used intensive workloads (microbenchmarks) and scientific parallel applications. Statistically, the results demonstrated that OpenNebula was 11.07% better using microbenchmarks and 8.41% with scientific parallel applications.

The specificity of color Doppler ultrasound to detect fetal hypoxia in pregnancy-induced-hypertension with thyroid dysfunction

The incidence of fetal hypoxia in pregnant women with Pregnancy-Induced Hypertension (PIH) is higher than normal pregnant women. Thyroid hormone is closely related to organism’s metabolism. In this study, Color Doppler ultrasound was used to diagnose fetal hypoxia in pregnant women with PIH to further explore the correlation of hemodynamic indexes and thyroid hormone levels. 70 cases of pregnant women with PIH were divided into thyroid-normal group (39 cases), hyperthyroidism group (12 cases) and hypothyroidism group (19 cases). The hemodynamic indexes of Middle Cerebral Artery (MCA) and Umbilical Artery (UA) were detected by color Doppler ultrasound. In hyperthyroidism and hypothyroidism groups, the hemodynamic indexes of MCA were lower and hemodynamic indexes of UA were higher than thyroid-normal group. The results of correlation tests showed that, the hemodynamic indexes of UA and fetal hypoxia were both significantly correlated to thyroid hormone levels respectively, in pregnant women with PIH. Therefore, the hemodynamic index of UA may be an index which can predict thyroid function status in pregnant women with PIH. Pregnant women with PIH and thyroid dysfunction are more likely to get fetal hypoxia than those with normal thyroid function. Color Doppler ultrasound is sensitive to detect the changes.
Chemical concepts inventory of Grade 12 learners and UP foundation year students

Abstract Incoming chemistry students at tertiary institutions have a variety of academic backgrounds that influence their prospects of success at first-year level. The proficiencies of incoming students are currently changing due to the introduction of outcomes-based education and new syllabi for physical science in secondary schools. In order to ensure a smooth transition from secondary to tertiary education, university lecturers should be well informed about the content knowledge, conceptual understanding and skills development of prospective first-year students. This study evaluates the proficiencies of Grade 12 learners in physical science in terms of a number of clearly identified problem areas: conceptual understanding, logical scientific reasoning, basic mathematical ability, knowledge of subject content and scientific process skills. A test instrument was developed that consisted mainly of conceptual questions rather than recall or algorithmic items. Paired questions (two-tier methodology) and pictorial representations were used extensively. A follow-up question about certainty of response was included for all fixed-response items in order to evaluate the influence of guessing on response distributions. The test instrument was administered at the end of the third term to Grade 12 learners taking Physical science at three schools in privileged environments (1 English and 2 Afrikaans medium) and four township schools, and to all University of Pretoria Foundation Year (UPFY) students. Analysis of results highlighted the generally poor performance of students from township schools and the significant improvement in performance after one year of intensive instruction of UPFY students, who generally came from similar or more impoverished backgrounds. The poor performance for all cohorts on basic concepts, such as the mole concept, stoichiometry and the limiting reagent, as well as on several special topics, indicates that students lack a sound basis for tertiary chemistry. Of real concern is the evidence of over-confidence obtained from the certainty of response analyses. This result indicates that respondents failed to judge the complexity and level of difficulty of questions accurately. Learners/students from all groups displayed weak understanding of events at molecular level. In order to address this situation, lecturers at tertiary level will have to actively promote conceptual understanding of all basic concepts in chemistry and resist the temptation to teach and assess mainly procedural fluency. Analysis of certainty of response data showed that the guess factor was less serious a complication than anticipated.
Conversion and Integration of Boundary Representations with Octrees *

This paper addresses the problems of converting polygon-based objects to octree-form and integrating 3D objects expressed in Volume Representation with others expressed in Boundary Representation. To achieve this the authors propose an approach which makes use of: (i) filling by octants, (ii) connectivity labeling, (iii) digitization of straight lines and polygons in 3D. Selected examples are given: among these, one deals with volumes enclosed by slightly inaccurate boundaries, as those generated, for instance, by the use of digitizing tablets; another deals with joining distinct volume-based objects with triangular digitized' tiles; another again simulates bone grafting.
Discrete-time fractional-order controllers

The theory of fractional calculus goes back to the beginning of the theory of di erential calculus but its inherent complexity postponed the application of the associated concepts. In the last decade the progress in the areas of chaos and fractals revealed subtle relationships with the fractional calculus leading to an increasing interest in the development of the new paradigm. In the area of automatic control preliminary work has already been carried out but the proposed algorithms are restricted to the frequency domain. The paper discusses the design of fractional-order discrete-time controllers. The algorithms studied adopt the time domain, which makes them suited for z -transform analysis and discrete-time implementation. The performance of discrete-time fractional-order controllers with linear and nonlinear systems is also investigated. Mathematics Subject Classi cation: 26A33, 93C15, 93C55, 93C80
The Magnitude of Diesel Particulate Matter in Underground Mine Workings: Advances in Real-Time Monitoring

A real-time Diesel Particulate Matter (DPM) monitor has been developed on the basis of the successful National Institute of Occupational Health and Safety (NIOSH) designed Personal Dust Monitor (PDM) unit. The objectives of a recently completed Australian Coal Association Research Program (ACARP) study were to modify the PDM to measure the submicron fraction of the aerosol in a real-time monitoring underground instrument. Mine testing focused on use of the monitor in engineering evaluations to determine how conditions can be improved. Studies, including a selection during Longwall (LW) moves as described in this paper, demonstrated how DPM concentrations from vehicles fluctuate under varying ventilation and operational conditions. Correlation between the current SKC DPM measurement system and real-time DPM monitors were conducted and results from six mines show a correlation between elemental carbon (EC) and the new monitor DPM mass ranging from . 51 to . 81 with R 2 >. 90. These differences are suspected to be due to variations from mine to mine in aspects such as mine atmospheric contamination, vehicle fleet variations, fuel type, engine maintenance, engine combustion efficiency, engine behaviour or interference from other submicron aerosol. Real-time monitoring readily reflects the movement of individual diesel vehicles and allows pin-pointing of high exposure zones such as those encountered where various vehicles work in areas of constrained or difficult ventilation. DPM monitoring approaches that have been available for some time based on shift average monitoring do not readily allow successful engineering evaluation exercises to determine acceptability of pollution levels. Identification of high DPM concentration zones allows efficient modification of mine ventilation, operator positioning and other work practices to reduce miners’ exposures without waiting for laboratory analysis results.
Prolylcarboxypeptidase protects from vascular dysfunction and promotes vascular repair

by GREGORY NICHOLAS ADAMS Prolylcarboxypeptidase (PRCP) is a cell surface protease that degrades peptides (including angiotensin II, des-Arg-bradykinin and alpha-melanocyte stimulating hormone) and activates plasma prekallikrein. The enzyme is highly expressed by endothelial cells where it activates prekallikrein to liberate the vasoactive peptide bradykinin. The following studies characterize the vascular phenotype of the PRCP-deficient (PRCPgt/gt) mouse. Compared to wildtype animals, PRCPgt/gt are hypertensive and demonstrate faster times to induced arterial thrombotic occlusion. PRCPgt/gt have increased levels of vascular reactive oxygen species (ROS) and the hypertensive, prothrombotic phenotypes are corrected by oral antioxidant treatment. The vascular dysfunction induced by PRCP depletion was observed in vitro by siRNA treatment of endothelial cells. Additionally, PRCPgt/gt mice show signs of defective angiogenesis and vascular repair. The animals have decreased
