Early Adolescents’ Emotional and Behavioral Difficulties, Student–Teacher Relationships, and Motivation to Defend in Bullying Incidents

Background: School bullying is a widespread phenomenon across the world, which involves bystanders who take on various roles. Motivation to defend victims is important to investigate because it helps us devise better, evidence-based, anti-bullying interventions. Objective: We aimed to determine whether students’ behavioral and emotional strengths and difficulties and student–teacher relationships

Fine crushing of iron ore through technical-economical optimization technologies

Since the Dawn of Man the metallic iron has been a giant issue for the daily life of humans by using for developments and generality prosper. This "hot" metal is still the most wanted and needed metal for all mankind. Sandvik Mining and Construction has for the last ten years increased our knowledge for the development for crushers, crushing and crusher automation and we have created new frontiersSince the Dawn of Man the metallic iron has been a giant issue for the daily life of humans by using for developments and generality prosper.

Vicarious Value Learning and Inference in Human-Human and Human-Robot Interaction

Among the biggest challenges for researchers of human-robot interaction is imbuing robots with lifelong learning capacities that allow efficient interactions between humans and robots. In order to address this challenge we are developing computational mechanisms for a humanoid robotic agent utilizing both system 1 and system 2-like cognitive processing capabilities. At the core of this processing

Using Multi-Agent Transport Simulations to Assess the Impact of EV Charging Infrastructure Deployment

Over the last two decades, electrification has gained importance as a means to decarbonise the transport sector. As the number of Electric Vehicles (EVs)increases, it is important to consider broader system aspects as well, especially when deciding the type, coverage, size and location of the charging infrastructure required. In this article, a Multi-Agent model depicting long distance transport i

The experimental determination of equilibrium Si isotope fractionation factors among H4SiO4 o, H3SiO4 and amorphous silica (SiO2·0.32 H2O) at 25 and 75 °C using the three-isotope method

The accurate interpretation of Si isotope signatures in natural systems requires knowledge of the equilibrium isotope fractionation between Si-bearing solids and the dominant Si-bearing aqueous species. Aqueous silicon speciation is dominated by silicic acid (H4SiO4 o) in most natural aqueous fluids at pH < 8.5, but forms H3SiO4 −, H2SiO4 2−, and polymeric Si species in more alkaline fluids. In th

Performance Estimation of a Traction Machine with Direct Cooled Hairpin Winding

Hollow and profiled conductors, which can be categorized as direct cooled conductors, are selected to develop a design proposal of an electrical machine with direct cooled hairpin type of winding. The objectives of this work are 1) investigating the benefits of direct heat removal when using hollow and profiled conductors, and 2) analyzing high frequency capability of these types of windings. Firs

To deeply understand the non-premixed swirl flame, the effects of two burner exit geometries on the non-premixed swirl flames modes were studied by performing OH-PLIF, PIV measurements and coupling LES with PDF combustion model numerically. The results showed that the stochastic PDF method can predict the swirl flow fields and detailed flame structures including local extinction. Two different qua

The role of plasma microseminoprotein-beta in prostate cancer : An observational nested case-control and Mendelian randomization study in the European prospective investigation into cancer and nutrition

Background: Microseminoprotein-beta (MSP), a protein secreted by the prostate epithelium, may have a protective role in the development of prostate cancer. The only previous prospective study found a 2% reduced prostate cancer risk per unit increase in MSP. This work investigates the association of MSP with prostate cancer risk using observational and Mendelian randomization (MR) methods. Patients

Allergic contact dermatitis caused by isobornyl acrylate in the Enlite glucose sensor and the Paradigm MiniMed Quick-set insulin infusion set

Background: The FreeStyle Libre glucose sensor has caused many cases of allergic contact dermatitis, and isobornyl acrylate (IBOA) in this sensor has been identified as one of the culprit allergens. Objectives: To report on the presence of IBOA in devices produced by Medtronic, namely, Enlite sensor and insulin infusion set Paradigm MiniMed Quick-set. Patients and Methods: Five patients reacting t

Agents in early development for treatment of bladder dysfunction–promise of drugs acting at TRP channels?

Introduction: In the lower urinary tract (LUT) several members of the TRP superfamily are involved in nociception and mechanosensory transduction. Animal studies have suggested a therapeutic potential of some of these channels, including TRPV1, TRPV4, TRPM8, TRPA1, and TRPM4, for treatment of bladder over- and underactivity and bladder pain disorders, but translation of this information to clinica

Crack-Growth Criteria and Crack Tip Models.

The current status of crack tip characterizations is reviewed. Several unresolved areas for further research are identified. Singular fields for stationary and moving crack tips in different non-linear materials are reviewed and special emphasis is put on the extension of the region where these fields dominate. The use of path-area integrals, asymptotically elastic crack tips, and crack initiation

A One-Step Solution Technique for Elastic-Plastic Self-Similar Problems

At self-similarity the strain history is implicit in and deducible from the strain field at each instance of the loading process. This fact is taken advantage of in a FEM-technique which allows the load to be applied in one single step, only, even when the incremental theory of plastic flow has to be used. Two self-similar problems are solved. Firstly an analytically solvable anti-plane strain craAt self-similarity the strain history is implicit in and deducible from the strain field at each instance of the loading process.

Using Elastic Plastic Plane-Stress Fem Programs to Compute Antiplane Strain

Elastic—plastic anti‐plane strain problems can be solved by using FEM programs developed for plane stress. The technique does not involve any manipulations with the FEM code, but is merely a matter of specialization and of translation of notation. Two analytically solvable cases are chosen for demonstration.
