Copper from vehicles disc brakes is one main contributor of the total copper found in the environment. Therefore, the U.S. Environmental Protection Agency (EPA) and the automotive industries started the Copper-Free Brake Initiative. The pad friction material is essentially composed of a binder, fillers, reinforcing fibres and frictional additives. Copper and brass fibres are the most commonly used
Epitaxial Bi-containing III–V crystals (III-V1-xBix) have attracted increasing interest due to their potential in infrared applications. Atomic-scale characterization and engineering of bulk-like III-V1-xBix properties (e.g., Bi incorporation and defect formation) are challenging but relevant to develop applications. Toward that target, we report here that the traditional surface-science measureme
Participation of stakeholders at the local level is evolving as a mechanism to address complex environmental problems, not least water pollution. Participation has been used as a tool for the economic and social empowerment of settlements within the catchment of the Korle lagoon in Ghana, particularly residents of the Old Fadama community that live in proximity to the lagoon. Using direct observat
This paper analyses regional public transport planning in Sweden. The aim is to provide an insight into how policy objectives are translated into action and to investigate how public transport measures are evaluated. The analysis is based on interviews with civil servants in five Swedish regions. Cost-benefit analysis is sparsely used (if ever) and the results further indicate that planning and ev
Surface enhanced Raman scattering (SERS) of pyridine adsorbed on Au@Pd core/shell nanoparticles has been investigated theoretically with quantum chemical method, generalized Mie theory and three-dimensional finite-difference time domain (3D-FDTD) method. We first studied the influence of the coated Pd on the electronic structure of Au nanoparticle, and compared the electronic structure of Au-20 cl
Eemian-Weichselian sequences, located outside the maximum limit of the Late Weichselian ice sheet, provide excellent opportunities for the discovery of continuous sedimentary records encompassing the whole Last Interglacial/Glacial cycle. Such a sequence is recorded in a borehole (117P) through the succession in a small kettlehole lake located at Medininkai, eastern Lithuania. The succession consi
A myoelectric control system for prostheses was developed and evaluated on six healthy subjects. These were able to control a computer-animated hand in real-time with a 20 Hz update rate. A data glove, equipped with joint angle sensors, was used to train the system and to evaluate the continuous predictions of joint angles. A linear envelop filter was used for EMG signal pre-processing and the rec
Studies were performed in guinea pigs to elucidate alterations in endogenous uterine norepinephrine (NE) levels and changes in the contractile response to exogenous NE following local sympathetic denervation, oophorectomy, or treatment with sex steroids. Both in intact and oophorectomized animals the myometrial NE concentration was reduced after sex steroid treatment (0.5 microgram 17-beta-estradi
Education reforms in Iran is the most recent endeavor of the theocratic state to enhance the vision of the revolution in creating homo-Islamicus (the committed Muslim) and provide strategies for the national education to meet the demands of a globalized and competing world. The reform is the interplay of a rigid interpretation of religion, international discourse and local needs. On one hand, it i
Official policies, academic discussions and public debates frequently address the potential risks and dangers of the use of Information and Communication Technologies (ICT) among children and youth. At the same time, however, digital policies in education create themselves new vulnerabilities for school children and youth that often go unnoticed as they occur within politically desired frameworks.
The ability for a damaged structure to withstand progressive collapse is often referred to as robustness. A robust building is characterized by the fact that the consequence of local damage is never more severe than the initial event. The way in which structural robustness is approached in the design of a building differs a great deal from one structural engineer to another. For a structure in con
The rich cultural heritage of China is becoming less relevant and forgotten as a result of rapid urbanization and modern lifestyles. This project aims to preserve the Chinese music heritage by designing an instrument based on the Chinese zither guzheng. Despite the rising interest of traditional instruments, there are factors that are holding people back from practicing them. There have been atte
A reporter is often required to report from different types of accidents, and this could be traumatic experiences. At the same time, a journalist is the only person who operates at these scenes without professional training in meeting persons in a state of shock. In the field of crisis coverage, there is much to learn regarding what consequences this will bring to the individual reporting from var
From a control design point of view, modern diesel engines are dynamic, nonlinear, MIMO systems. This paper presents a method to find low-complexity black-box dynamic models suitable for model predictive control (MPC) of NOx and soot emissions based on on-line emissions measurements. A four-input-five-output representation of the engine is considered, with fuel injection timing, fuel injection dur
Current consumption and production cannot rely any longer on traditional linear approach to satisfy increasing needs of the growing population. Instead, the principles of circularity should be applied. One way to do is to adopt industrial symbiosis approach, which entails physical exchange of materials, energy, water and/or by-products between traditionally separate industries. However, the uptake
This thesis investigates accessible information to the “interested citizen” about EU-related matters in his/her city, with a theoretical method that departs from Dahl’s (1998) definition of democracy, and focuses especially on the criteria of enlightened understanding. The study consists of analyses of online information and city council debates as well as interviews and mail correspondence with l
Studien syftade till att undersöka hur uppmärksamheten påverkas av emotioner med olika motivationell intensitet. Tidigare forskning har visat att det är valensen hos emotionen som avgör om uppmärksamheten riktas mot delen eller helheten, men nyare studier har pekat på att det är den motivationella intensiteten (MI) som spelar en avgörande roll. I vår studie (n=81) undersöktes positiva emotioner meThe purpose of the study was to investigate how attention is influenced by emotions with different Motivational Intensity (MI). Previous research found that it is the valence of an emotion that influences attention (broadens or narrows), but more recent studies have focused on Motivational Intensity (MI). In our study (n=81), we examined positive emotions with high MI, positive emotions with low M
In recent years, Ethiopia’s double-digit growth rates are regarded as an economic miracle. As the government assigned a key role for the private sector to promote industrialization, this paper investigates the current state of the private sector in the manufacturing industry and the extent it contributes to the growth and development in Ethiopia. An exploratory case study approach was implemented
By addressing an absence of implementation studies, this master thesis aims to examine the implementation of the FRESH health policy in schools in Lombok, Indonesia. The method used is a qualitative field study based on empirical material consisting of interviews with representatives from implementing organizations and teachers designated to be “FRESH coordinators” in schools. By utilizing dimensi
