Enhanced aging properties of HKUST-1 in hydrophobic mixed-matrix membranes for ammonia adsorption.

Metal-organic frameworks (MOFs) in their free powder form have exhibited superior capacities for many gases when compared to other materials, due to their tailorable functionality and high surface areas. Specifically, the MOF HKUST-1 binds small Lewis bases, such as ammonia, with its coordinatively unsaturated copper sites. We describe here the use of HKUST-1 in mixed-matrix membranes (MMMs) prepared from polyvinylidene difluoride (PVDF) for the removal of ammonia gas. These MMMs exhibit ammonia capacities similar to their hypothetical capacities based on the weight percent of HKUST-1 in each MMM. HKUST-1 in its powder form is unstable toward humid conditions; however, upon exposure to humid environments for prolonged periods of time, the HKUST-1 MMMs exhibit outstanding structural stability, and maintain their ammonia capacity. Overall, this study has achieved all of the critical and combined elements for real-world applications of MOFs: high MOF loadings, fully accessible MOF surfaces, enhanced MOF stabilization, recyclability, mechanical stability, and processability. This study is a critical step in advancing MOFs to a stable, usable, and enabling technology

Tiffany & co.: perception of the brand and the luxury Jewelry industry by Gen Z and strategic recommendations on how to approach them

The aim of this work project is to identify and formulate strategic recommendations for the brand Tiffany & Co. in Germany on how to address the target group Gen Z. Gen Z emerges as a new and very important consumer group within the jewelry industry. The elaborated strategies are grounded on conducted research for primary and secondary data and provide the basis for the succeeding analysis and conclusions. The brand’s main weakness and recommendation being discovered within this thesis is the development of a communication strategy under careful consideration of Gen Z’s demands and expectations in products and brand

How do companies learn from internal/external experience?

SummaryThe thesis is a response to the fact that the Norwegian Petroleum Safety Authority questions the learning ability of the petroleum companies that are operating on the Norwegian continental shelf, despite that this is something that has been focused on for decades. The issue of learning has recently become increasingly important because of the increasingly number of oil & gas companies operating on the Norwegian continental shelf. The thesis aims at study factors of importance for the learning ability of companies (the thesis is not necessarily just aimed at oil companies) with regards to internal/external experience. The terms internal/external experience is explained more in detail in the introduction chapter. In order to reveal inhibitors/promoters towards a learning organization it where created following research questions:? What characterizes a learning organization?? What inhibitors to learn from safety experience exist?? What promoters to learn from safety experience exist?? What general and specific advices can be given to promote learning from internal/external experience?In order to answer these questions, it where chosen a qualitative research approach based on a semi-qualitative interview guide which aimed at reveal the experience of nine employees within three different oil companies with regards to learn from unwanted incidents/conditions, as well as systems to assure learning within their current employer. The interview results provided the basis for the empirical part of the thesis by using grounded theory to code the results in order to find out which issues that were repeatedly mentioned, in order to reveal patterns and also to see what issues that were not given so much thought. The empirical results where then compared to prewritten theory, which was developed by study known literature within organizational learning. It where on the basis of this comparison developed recommendations for how to learn from internal/external experience. The recommendations are applicable for the oil industry as a whole, and could probably also be used by companies in other industries. The main findings in the thesis can be summarized to the following content:? Cooperate across internal/external boundaries in order to learn from each other and ensure that everyone/as many as possible are able to participate/express their concerns and take signals from different actors seriously ? Be open for criticism even of established systems ? Ensure clarity regarding information, expectations, responsibilities, connections with following measures, distinguishing of incidents and different types of knowledge? Make things easy to follow/summarize ? Ensure that investigations performed and procedures developed are backed by existing ground rules? Map inabilities, long time issues and take into account conflicting interests as well as different assumptions? Ensure enthusiasm to new solutions and avoid giving blame? Important with a proactive management which do not back down from problems but instead engages in issues? Develop arenas where the aim is to study improvement

Medico-Legal Aspects of the Electroencephalogram

Brain injuries are difficult to prove and the lawyer must use all demonstrative evidence available to him to make the jury aware of the injury to his client. The electroencephalogram, though it has only been used as a diagnostic tool and as demonstrative evidence for the last fifteen to twenty years, is becoming more important in this field. It is becoming a more exact science and, it is believed, will be used more widely in the future. There does not appear to be any great problem of admissibility where they are properly identified, performed by competent technicians, using adequate equipment, and which accurately represent the information they are intended to reveal. If they serve the cause of justice and are relevant and material to the medical issues to be determined, courts everywhere will admit them for tha tpurpose

3D printing is a transformative technology in congenital heart disease

Survival in congenital heart disease has steadily improved since 1938, when Dr. Robert Gross successfully ligated for the first time a patent ductus arteriosus in a 7-year-old child. To continue the gains made over the past 80 years, transformative changes with broad impact are needed in management of congenital heart disease. Three-dimensional printing is an emerging technology that is fundamentally affecting patient care, research, trainee education, and interactions among medical teams, patients, and caregivers. This paper first reviews key clinical cases where the technology has affected patient care. It then discusses 3-dimensional printing in trainee education. Thereafter, the role of this technology in communication with multidisciplinary teams, patients, and caregivers is described. Finally, the paper reviews translational technologies on the horizon that promise to take this nascent field even further
