In this work, physical and chemical characterization of El- Lajjoun retort water from oil shale pyrolysis process has been carried out. Comparison of different treatment methods for the major components which could affect the design and operation of any set of wastewater treatment process were conducted. The removal of phenol and ammonia using activated carbon after 12 hour resident time were 93 a
This chapter illustrates how quantum chemical calculations can be used to elucidate structural and functional aspects of tetrapyrrole cofactors, focusing on porphyrins, cobalamins, coenzyme F430, and chlorophyll. A particular emphasis is put on the biochemical significance of axial ligands, which can tune the function of the tetrapyrroles. With the use of quantum chemical calculations, it is possi
This paper describes the research stimulated by a fundamental shift that is occurring in the manufacture and marketing of aero engines for commercial and defence purposes, away from the selling of products to the provision of services. This research was undertaken in an aerospace company, which designs and manufactures aero engines and also offers contracts, under which it remains responsible for
Arbetet utreder faderskapspresumtionen och närliggande rättsområden. Syftet med detta är att granska presumtionen och utvärdera om denna är att anse fyll-ler sitt syfte. Detta görs genom att analysera såväl hur det sett ut historiskt som att konstatera hur den gällande rätten ser ut. Detta har även ställts emot de intressen som finns i samhället, hos föräldrarna samt principen om barnets bästa. HThe project audits the presumption of fatherhood in the Swedish legal system and related legal areas. This is done to evaluate if the presumption is fulfilling its purpose. To achieve this a thorough analysis of the subject is conducted. The history of the legal area is explored, and the applicable law is reviewed. The interests in of the different involved parties such as the parents and the publ
Fundamental limits on scattering metrics such as absorption, extinction, and Purcell's factor are formulated by separating a scattering structure into controllable and uncontrollable regions. We present each bound as a special case of a general methodology based on the method of moments and convex optimization.
Testing of autonomous systems is extremely important as many of them are both safety-critical and security-critical. The architecture and mechanism of such systems are fundamentally different from traditional control software, which appears to operate in more structured environments and are explicitly instructed according to the system design and implementation. To gain a better understanding of a
Lean construction principles have been successfully adopted in a variety of industries to increase project management quality. This paper addresses maintenance planning in Sweden and analyses its effectiveness in the framework of lean construction principles. To investigate the status and improvement potential of maintenance contractors’ performance, the study focuses on the detailed planning proc
α-Synuclein (αSyn) is a neuronal protein predominantly found at the synapse, involved in vesicle trafficking. αSynaggregates are also the main component of Lewy bodies, the hallmarks of Parkinson’s disease. Interactions between the N- and Cterminiof αSyn play crucial roles in its behavior in solution, membrane binding, and aggregation. Studying these interactionsprovides valuable insights into theα-Synuclein (αSyn) is a neuronal protein predominantly found at the synapse, involved in vesicle trafficking. αSyn aggregates are also the main component of Lewy bodies, the hallmarks of Parkinson’s disease.

In low-and middle-income countries, inadequate sanitation results in faecal contamination of the water used by urban farmers for irrigation. Consumers of raw contaminated vegetables run the risk of developing diarrhoeal diseases and helminth infections, which are a leading cause of under-five mortality and impact the well-being and productivity of millions of adults. This review identifies the evi
This article traces how Yazidi genocide recognition is reworked across juridico-political domains in Germany, drawing on multi-sited ethnographic fieldwork conducted between August 2025 and February 2026 and analysis of criminal judgments and asylum decisions. It argues that recognition does not operate as a stable legal achievement but takes on shifting meanings as it moves across institutional s
Background: Documentation of older people’s end-of-life care should cover the care given and provide an overview of their entire situation. Older people approaching the end of life often have complex symptoms, live with bodily losses, and face an unknown future in which existential aspects come to the forefront. Knowledge of the existential aspects recorded in palliative care documentation is spar
According to conventional wisdom, improving energy efficiency is an easy way to mitigate climate change and improve energy security, though the reduction in energy intensity in developed economies is largely due to offshoring energy-intensive production to developing countries. This chapter presents a contrarian view. Theory, historical evidence, and time series analysis suggest that the economy-w
Leaders of today need to achieve well in terms of task performance, perceiving low stress, and having high levels of work engagement. One may ask whether trait-based leadership resource factors can be identified and how such resource factors might relate to task performance, perceived stress, and work engagement. Our aim was to test the hypothesis, derived from Hobfoll’s motivational Conservation
