Application of Benchmark Examples to Assess the Single and Mixed-Mode Static Delamination Propagation Capabilities in ANSYS

The application of benchmark examples for the assessment of quasi-static delamination propagation capabilities is demonstrated for ANSYS. The examples are independent of the analysis software used and allow the assessment of the automated delamination propagation in commercial finite element codes based on the virtual crack closure technique (VCCT). The examples selected are based on two-dimensional finite element models of Double Cantilever Beam (DCB), End-Notched Flexure (ENF), Mixed-Mode Bending (MMB) and Single Leg Bending (SLB) specimens. First, the quasi-static benchmark examples were recreated for each specimen using the current implementation of VCCT in ANSYS . Second, the delamination was allowed to propagate under quasi-static loading from its initial location using the automated procedure implemented in the finite element software. Third, the load-displacement relationship from a propagation analysis and the benchmark results were compared, and good agreement could be achieved by selecting the appropriate input parameters. The benchmarking procedure proved valuable by highlighting the issues associated with choosing the input parameters of the particular implementation. Overall the results are encouraging, but further assessment for three-dimensional solid models is required.
Upper secondary school transitions: an empirical analysis

Educational choices made by 15 year olds represent a high stake moment in the Swiss highly differentiated tracked school system. This thesis thus proposes an empirical analysis of upper secondary school transitions under four different angles using exhaustive registry data for a single Swiss Canton, Geneva. Chapter 3 assesses how transition opportunities are affected (and constrained) by social capital endowments and migration background. Chapter 4 looks at the impact of the age at first tracking on the smoothness of subsequent upper secondary school transitions. Chapter 5 focuses on transitions to apprenticeship training and examines apprentices' pathways. Chapter 6 deals with transitions across modes of training within vocational education and training, examining the impact of changing modes of training on the qualification probability on the one hand, and on the number of years necessary to qualify on the other.

Comparing the effects of dezocine with lidocaine on prevention of propofol injection pain in adults: a prospective randomized double-blind trial

Background Propofol injection pain (PIP) is common and may decrease patient comfort. The aim of this study was to compare the effects of dezocine with lidocaine on prevention of PIP.Methods 235 patients, who scheduled for elective surgery, aged 18–80 years and American Society of Anesthesiologists (ASA) I or II, were randomly assigned into five groups (n = 47 each). All patients were induced through the dor­sal hand vein or antecubital vein. The five groups were given the following medication intravenously: saline (Group I), lidocaine 20 mg (Group II), lidocaine 40 mg (Group III), dezocine 2 mg (Group IV) and dezocine 4 mg (Group V). Twenty seconds later all patients received a propofol infusion and were asked to grade pain or discomfort in the hand or forearm according to a four-point scale until anesthesia.Results Three groups showed a significantly lower incidence of total PIP than Group I: Group III (OR [Odds ratio]: 0.39 (0.16, 0.93)); Group IV (OR: 0.21 (0.09, 0.51)) and Group V (OR: 0.12 (0.05, 0.30)). Group IV showed a significantly lower incidence of total PIP than Group II (OR: 0.32 (0.13, 0.77)). Group V showed a significantly lower incidence of total PIP than Group II (OR: 0.15 (0.06, 0.39)) or Group III (OR: 0.30 (0.13, 0.72)). Conclusion Dezocine is a novel agent to alleviate PIP and appears to some extent to be more effective than lidocaine.
Nucleolin: a prognostic marker in cancer?

Nucleolin, a major protein of the nucleolus which is required for cell proliferation is the subject of numerous studies in the field of oncology. Many studies suggest that the level of expression of nucleolin and its cellular localization could be an indication of the clinical outcome in several cancers. Quite logically for a protein required for the cancer cells to increased protein synthesis, a correlation between the high level of nucleolin expression and the poor prognosis of the patients is often reported. Unexpectedly, in several studies it was also found that a low nucleolin expression could be also associated with an unfavorable prognosis. In these commentary I discuss these studies and the possible implications for using nucleolin as a prognostic marker in oncology.
The effect of essential oils on cholesterol content in chicken meat

The study aimed to investigate cholesterol content in chicken breast and thigh muscles by the influence of feed supplements of various content of essential oils. The experiment was carried out under practical conditions in a poultry farm with broiler chickens of the Cobb 500 hybrid combination according to the feed supplement used thyme essential oil, cinnamon essential oil, commercial citrus fruit essential oil, and their combination. The control group was without the use of experimental feed supplements and commercial coccidiostats were used in their feed mixtures. The experiment lasted 40 days in welfare conditions. Broiler chickens were used for sample preparation of breast and thigh muscles with the skin and their analysis for dry matter, fat and cholesterol contents. Samples were analyzed using a Nicolet 6700 FT-IR Fourier transform infrared spectrometer. The results were processed by the SAS system program, version 8.2. The results, which were evaluated, indicated a tendency to reduce the cholesterol content in chicken breast muscle due to cinnamon essential oil and the combination of cinnamon essential oil with citrus fruit essential oil as well as thyme essential oil with citrus fruit essential. In the achieved results of dry matter, fat, and cholesterol content in breast and thigh muscles, the difference between the effects of the used feed supplements based on essential oils and concerning the control group were not statistically significant p >0.05. The correlation was a statistically significant strong linear relation only between dry matter content and fat content due to thyme and cinnamon essential oils. In conclusion, it was stated that the investigation of the feed supplement effect based on essential oils is an open question concerning the production of safe food of animal origin.

Solrun Brenk Rønning Stål Bjørkly 1Faculty of Health Sciences and Social Care, Molde University College, Molde, Norway; 2Centre for Research and Education in Forensic Psychiatry, Oslo University Hospital, Oslo, Norway Background: An important goal in mental health education is for students to develop their ability to provide care and help to people with different degrees of mental problems. Positive experiences with the use of clinical role-play and subsequent reflection inspired us to investigate whether previous empirical studies had evaluated similar methods of teaching and to scrutinize the effects on students’ development of therapeutic skills and clinical reflection. Method: An integrative review was conducted to search the literature for findings from both qualitative and quantitative research. Systematic searches of literature were done in Ovid (MEDLINE, PsycInfo), Cinahl, Cochrane, ScienceDirect, SweMed, Norart, ProQuest, and Google Scholar. Results: The systematic literature search provided 42 full-text articles and four articles met the inclusion criteria. The results suggest that role-play in health education enhances students’ therapeutic and communicative skills. Nevertheless, there is limited research on the use of roleplay in teaching therapeutic skills, and few studies that investigate how role-play affects students’ reflections on own practice. The literature search did not discover studies investigating whether practicing role-play in educational settings has consequences for clinical practice. Conclusion: Based on this current review, role-playing in supervised groups seems to promote reflection and insight not only for students in the patient and therapist roles, but also for peers observing the group sessions. According to the included studies, clinical roleplay facilitates helper–user equality and increases students’ involvement, self-efficacy, and empathic abilities in mental health practice.
Automated Microassembly Using an Active Microgripper with Sensorized End-Effectors and Hybrid Force/Position Control

This work proposes the use of an active microgripper with sensorized end-effectors for the automation of the microassembly of 3D hybrid MOEMS. Each of the two fingers of the microgripper is composed of a piezoelectric actuator with an integrated piezoresistive force sensor. The integrated force sensor presents innovative performances compared to the existing force sensors in literature. The force sensors provide the ability to measure the gripping forces applied by the microgripper to grasp a microcomponent and estimated the contact forces between the microcomponent and the substrate of microassembly. A dynamic nonlinear model of the microgripper is developed. A hybrid force/position control is used for the automation of the microassembly. In the hybrid force/position control formulation, some axes are controlled in position and others are controlled in force. For the force controlled axes, a new nonlinear force control scheme based on force tracking sliding mode impedance control is proposed with parameter estimation. Using the proposed hybrid force/position control scheme, full automation of the microassembly is performed, notably for the guiding of a flexible component in a rail.

This is Volume 1 of a two-volume report and includes the results of studies preparatory to a detailed sensitivity analysis for the FHWA pavement structural model VESYS IIM, comparisons of predicted and measured pavement performance and recommendations for improvements to VESYS IIM. Volume 2 reports the results of the detailed sensitivity analysis itself. VESYS IIM is a comprehensive but very complex computer program currently requiring some 67 input values, about 27 of which are program control variables and the rest actual independent variables. Comparisons of VESYS IIM predicted responses to those actually measured for certain AASHO Road Test and Brampton Test Road Sections were made to test VESYS IIM capability for rational predictions. The effort is discussed in detail, and the results are presented.
Wake Shape and Height Profile Measurements in a Concave Open Channel Flow regarding the Target in DONES

Wakes appearing downstream of disturbances on the surface of a water flow in a concave open channel were examined experimentally. The investigated channel geometry was similar to the liquid lithium target in DONES (Demonstration fusion power plant Oriented NEutron Source). The objective of the measurements was to analyze the effect of a disturbance on the downstream layer thickness. For measuring the height profiles in the channel, an optical measurement system based on laser triangulation was developed. It was shown that the wake of the undisturbed flow emerged from the nozzle corner, which was in accordance with analytical solutions. For sufficiently large disturbances at the nozzle edge, the height profiles located downstream showed symmetrical minima and maxima on both sides of the disturbance. The wake depth strongly depended on the diameter and penetration depth of the disturbance, as well as the circumferential position in the channel, which yields to a critical wake depth of one millimeter for the lithium target in DONES.
Stability Enhancement and Blackout Prevention by VSC Based HVDC

This paper deals with the operation and performance of VSC (voltage source converter) based HVDC (high voltage direct current) interconnecting two extremely weak AC networks, the experience of Caprivilink project. It is shown in the paper that the HVDC converter automatically provides the supreme voltage and frequency stabilizing function when a critical situation is detected, no matter the disturbances appeared in sending end or receiving end AC networks. This supreme voltage and frequency stabilizing function makes it possible to avoid the blackout even if all the generators are tripped under an extra-ordinary worst contingency. By plots of recorded transients, the paper will show how the eventual blackouts are avoided.

Wind energy potential, resource assessment and economics of wind power at Qamu, Navua (18° 13' S, 178° 10' E) were analyzed using wind speed data collected by Fiji Department of Energy in 1980. Annual and seasonal variation in wind speed, direction and power density were analyzed using Wind Atlas Analysis and Application Program (WAsP). Weibull statistics for the shape factor and scale parameter at 10 m are 1.65 and 5.2 m/s respectively. The cost of generating electricity from Vergnet 275 kW wind turbines is FJD 0.08/ kWh and a payback period of ~10 y.
Pulmonary vein isolation using cryoballoon ablation versus RF ablation using ablation index following the CLOSE protocol: A prospective randomized trial

The single procedure success rates of durable pulmonary vein isolation (PVI) for paroxysmal atrial fibrillation (AF) vary between 80% and 90%. This prospective, randomized study investigated the efficacy of cryoballoon PVI (CBA) versus PVI with radio‐frequency (RF)‐energy following the CLOSE protocol (ablation index [AI], interlesion distance ≤6 mm, surround flow catheter) in terms of single‐procedure arrhythmia‐free outcome and safety.
Measurement system for fast power and energy rating of photovoltaic devices

This thesis presents a new type of solar simulator and new measurement methods that allow for fast power rating of photovoltaic devices and for fast performance measurements for energy rating and energy yield predictions indoors under controlled, and more realistically simulated outdoor conditions. A novel indoor measurement system for photovoltaic device characterisation based on light emitting diodes (LEDs) as the light sources is described. The solar simulator is capable of reproducing spectral changes seen in natural sunlight, with its intricacies of variable air mass and weather conditions, to a better match than previously possible. Furthermore, it allows measurements under varying light intensity and device temperature. The prototype LED-based solar simulator developed is characterised and its measurement quality is analysed. The system achieves a class BAA solar simulator classification with a class B spectral match, class A light intensity uniformity and a class A temporal stability. It is the first system of its kind that meets the standards of a solar simulator in spectral match to the standard sunlight spectrum and in terms of minimum light intensity. An uncertainty analysis shows that calibration uncertainty for crystalline silicon solar cells is 5% in maximum power with a 95.45% level of confidence. Recommendations for further versions of the solar simulator are given and show potential of reducing this uncertainty down to 2.9% across all measurement spectra (1.8% with a primary calibrated reference cell). A new method for automated power-rating of single- and multi-junction devices is developed. The method uses a unique spectral response measurement and fitting method. It eliminates the need of external measurement equipment for determining spectral response. A simulated characterisation of an amorphous silicon single- and double-junction solar cell show accuracy of better than 0.5% in maximum power. First measurements on the LED-based solar simulator show a measurement error of 4.5% in maximum power, which is due to a lack of measurement feedback of spectral output and measurement irradiance. The first three-dimensional performance matrix for use in photovoltaic energy rating is reported, utilising the LED-based solar simulator. Device characteristics are measured indoors under varying irradiance, temperature and spectrum. A measurement method is detailed and utilised on a crystalline and amorphous silicon solar cell. It allows for the first time a direct investigation of spectral effects on photovoltaic devices under controlled conditions. Results show that amorphous silicon devices are very sensitive to changes in spectrum. Thus, spectral effects should not be neglected in energy yield predictions for such devices.
Experienced durability of maintenance treatments

The durability of a maintenance treatment depends on the conditions when the treatment was applied, such as road condition, traffic and environmental factors. For example, surface treatment carried out on a road with structural defects will have a shorter durability. Durability also differs between different countries due to differences in maintenance standards and strategies. The experienced durability is based on facts but has the disadvantage that considered treatments are based on older technology. In the same time, typically, it is not known if the pavement condition was similar when the treatments were applied, and there are usually changes in traffic over time. In Sweden, all pavement treatments longer than 100 m are required to be reported. In analysis of experienced durability app. 300 000 projects have been analyzed. The reported pavement treatment database covers a long period and contains historical information (several treatments at the same section). The durability of treatments is calculated as the age of a treatment when a new treatment is carried out. This means that the durability is valid for treatments that were carried out back in time. Another method discussed in the paper is time-to-event studies. This paper will show results of analyses and discuss problems in establishing expected durability.
Drone Detection using Audio Analysis

Drones used for illegal purposes is a growing problem and a way to detect these is needed. This thesis has evaluated the possibility of using sound analysis as the detection mechanism. A solution using linear predictive coding, the slope of the frequency spectrum and the zero crossing rate was evaluated. The results showed that a solution using linear predictive coding and the slope of the frequency spectrum give a good result for the distance it is calibrated for. The zero crossing rate on the other hand does not improve the result and was not part of the final solution. The amount of false positives increases when calibrating for longer distances, and a compromise between detecting drones at long distances and the number of false positives need to be made in the implemented solution. It was concluded that drone detection using audio analysis is possible, and that the implemented solution, with linear predictive coding and slope of the frequency spectrum, could with further improvements become a useable product.
Impact of Human Communication in a Multi-teacher, Multi-robot Learning by Demonstration System

A wide range of architectures have been proposed within the areas of learning by demonstration and multi-robot coordination. These areas share a common issue: how humans and robots share information and knowledge among themselves. This paper analyses the impact of communication between human teachers during simultaneous demonstration of task execution in the novel Multi-robot Learning by Demonstration domain, using the MRLbD architecture. The performance is analysed in terms of time to task completion, as well as the quality of the multi-robot joint action plans. Participants with dierent levels of skills taught real robots solutions for a furniture moving task through teleoperation. The experimental results provide evidence that explicit communication between teachers does not necessarily reduce the time to complete a task, but contributes to the synchronisation of manoeuvres, thus enhancing the quality of the joint action plans generated by the MRLbD architecture.

ANTITROMBOTIC ACTIVITY OF A NEW BENZIMIDAZOLE DERIVATIVE WITH A SPATIALLY DIFFICULT PHENOLIC SUBSTITUTE IN ITS STRUCTURE

The aim of the study was to investigate antithrombogenic properties of compound RU-1144 with previously identified pronounced antiplatelet and antioxidant activities. The thrombosis induced by Ferric chloride (FeCl3) was carried out in rats’ carotid artery, in comparison with the known antiaggregant drugs - acetylsalicylic acid (ASA) and clopidogrel, as well as with the antioxidant preparation - ethylmethylhydroxypyridine succinate (EMHPS). Materials and methods. The antithrombotic activity of compound RU-1144 was studied on the model of the rats with carotid artery thrombosis, induced by the application of 50% ferric chloride (FeCl3), and the Global Thrombosis Test model (the Görög Thrombosis Test). The evaluation of this type of activity was carried out by prolonging the time of a blood clot formation. The studies of the compound RU-1144 effect on the bleeding time parameter were performed in mice. Acetylsalicylic acid, clopidogrel and EMHPS were used as reference drugs.Results. The antithrombotic effect of the RU-1144 substance revealed in the model of arterial thrombosis induced by the application of ferric chloride (FeCl3), exceeded that of both acetylsalicylic acid and clopidogrel by 3.5 times and that of EMHPS by 2.9 times. In the model of the in vitro Global Thrombosis Test (the Görög Thrombosis Test), compound RU-1144 reduced the thrombogenic potential of the blood equally with acetylsalicylic acid and clopidogrel. The assessment of “the bleeding time”, caused by the RU-1144 substance, showed that the prolongation of bleeding was twice as less pronounced than that caused by ASA and clopidogrel.Conclusion. The performed studies demonstrated a pronounced antithrombotic activity of compound RU-1144, which exceeded that of acetylsalicylic acid, clopidogrel and EMHPS, while the ability to prolong the bleeding time was reliably lower than that of reference drugs.Abbreviations: EMHPS-ethylmethylhydroxypyridine succinate; ASA - acetylsalicylic acid.
