During protoplanetary disk formation, dust grains located in the outer disk retain their pristine icy composition, while solids in the inner stellar-heated disk undergo volatile loss. This process may have left a fossil record in Solar System material, showing different nucleosynthetic imprints that have been attributed to different degrees of thermal processing. However, it remains unclear how a
Cloud RAN (C-RAN) is a promising paradigm for the next generation radio access network infrastructure, which offers centralised and coordinated base-band signal processing in a cloud-based BBU pool. This requires extremely low latency responses to achieve real-time signal processing. In this paper, we analysed the challenges to introduce cloud native model for signal processing in C-RAN. We studie
An interesting class of non-Gaussian stationary processes is obtained when in the harmonics of a signal with random amplitudes and phases, one allows also for frequencies to vary randomly. In the resulting models, the statistical distribution of frequencies determines the process spectrum while the distribution of amplitudes governs the process distributional properties. Since decoupling the distr
Altered sensory processing has been linked to symptoms of obsessive-compulsive disorder (OCD) and anxiety disorders (ADs) in youth, but few studies have examined sensory processing in clinical samples and no study has analyzed self-report data from youth meeting diagnostic criteria for OCD or ADs. This study included 86 youth with OCD, 82 youth with ADs, and 46 youth without psychiatric disorders.
Popular Abstract in Swedish Det finns tre typer av makromolekyler som är grundläggande för allt liv på jorden: DNA, RNA och proteiner. I varje cell i kroppen finns en kopia av vår arvsmassa, DNA. Denna består av gener som avkodas först till RNA och sedan till tiotusentals proteiner. Alla gener är inte aktiva i varje cell eller i varje tidpunkt. Proteiner kontrollerar nästan alla aspekter av det viProteins are complex structures and years of research have been spent on attempts to understand their complexity. The non-covalent interactions involved in protein folding are: hydrophobic effect, electrostatic interactions, van der Waals interactions and hydrogen bonding. It has been of great interest to address the importance of each of those interactions in proteins. While hydrophobic effect is
The limited thermal stability of polyhydroxyalkanoates (PHAs) hinders their wide applicability, and methods to improve the processability of these biopolyesters are needed for efficient processing, e.g. by melt extrusion. In the present study we have shown by isothermal gravimetry, dynamic rheology and molecular weight analysis that the thermal stability of the PHAs at the processing temperature c
Purpose – The purpose of this paper is to report a case study that qualitatively describes and analyses teachers’ discussions when planning and evaluating lessons under supervision, and what is described is the focus on their reasoning, the activities decided upon and how they decided to assess the pupils’ learning outcomes when transforming formal curriculum objectives for English as a foreign la
Aims. DE Boo is a unique system, with an edge-on view through the debris disk around the star. The disk, which is analogous to the Kuiper belt in the Solar System, was reported to extend from 74 to 84 AU from the central star. The high photometric precision of the Characterising Exoplanet Satellite (CHEOPS) provided an exceptional opportunity to observe small variations in the light curve due to t
Denna studie ämnar undersöka samspelet mellan den mediala gestaltningen av en stad samt de strategier som används i försök att påverka densamma. Studien avser därmed öka kunskapen om skapandet och förmedlandet av platsvarumärken samt den strategiska kommunikationens betydelse för denna process. Med en hermene-utisk ansats har kvalitativa intervjuer samt kvantitativ såväl som kvalitativ inne-hållsa
Gruvdrift i yttre rymden har under de senaste åren vuxit fram som en reell möjlighet. Privata företag ligger i bräschen med att utveckla ny teknik för att uppnå utnyttjandet av resurser i yttre rymden. De rättsliga förutsättningarna är fortfarande ett hinder för sådana aktiviteter då de stora rymdfördragen inte uttryckligen förbjuder eller tillåter det. Problemet kring denna typ av gruvdrift har aMining in outer space has in recent years emerged as a real possibility. Private companies are at the forefront of developing new technology to achieve the exploitation of resources in outer space. The legal conditions are still a barrier because of that the large space treaties do not expressly prohibit or allows such a venture. The problem surrounding this type of mining has materialized even mo
Urban transportation is becoming increasingly challenging in the face of growing cities, urban sprawl and a rising trend in car use. Beyond the direct impacts of motorized transports, the development of extensive car infrastructure exacerbates social differences, especially in urban areas. The social dimension of transport is however marginalized in the current model of transport planning and sign
Bankbranschen är en bransch som präglas av förtroende. Förtroende mellan banken och dess kunder, banken och statliga institutioner, banken och dess anställda och sist men inte minst aktiemarknadens förtroende för bankens styrelse och ledning i det fall den är börsnoterad. Denna uppsats har undersökt huruvida det finns särskilda krav på banktjänstemän och ifall det finns liknande krav på förtroendeThe banking industry is one that is pervaded by trust: trust between the banks and their customers, the banks and different state departments, the banks and their employees and last, but not least, the stock markets trust for the banks executive boards and management if the bank is listed on a stock exchange. This essay has examined whether or not there are special demands on employees in the bank
Being stateless, roughly means being without a citizenship of any nation. This is the definition of being stateless in legal terms, called de jure statelessness. There is also statelessness that entails being without the efficient protection of one’s nation, called de facto statelessness. Two groups of stateless migrants that correspond to these definitions are Bidoons from Kuwait and Palestinians

On January 1, 2010 Transportstyrelsen became responsible for withdrawing taxi driver licenses, which before was a responsibility of länsstyrelsen. In the process of a withdrawal, bureaucrats at these public authorities implement a law, made by lawyers, probably meant to be used by lawyers. The objective of the law, which the decisions of withdrawal are founded on, has proven to be that no improper
Organizational Learning is regarded as a major factor that leverages the competitive advantage of a company. Nowadays, many enterprises are relying on Knowledge Management systems for various purposes, but the utilization of these systems for enhancing Organizational Learning has not reached its optimum level. In the actual context, the purpose of the research is to determine how Knowledge Managem
This thesis examines Swedish forest biological soil research in its newly institutionalized form, performed in relation to industrialized silviculture, during the years 1916-1923. The main objective is to analyze how the early forestry scientists pursued, and legitimized, knowledge on forest soil for industry and society, and also to draw attention to less considered empirics within history of sci
The thermal model and simulation of vehicles components is necessary within the development phase of the vehicle production process. It is important to understand the thermal processes of high temperature components in the vehicle, such as the exhaust system. The exhaust system presents a high thermal activity that increases the temperature of the exhaust system itself and the nearby surrounding e
Innovation is a key factor for sustainable growth and profitability of companies. As innovative, small, start-ups tend to grow, it is important to understand how the innovation performance can be maintained during the growth. The often relatively unstructured organisations of small companies need to implement structures in order to control the operations as they grow. There are contradictions and
Through economic openness, increased capital mobility and the resulting competition to innovate, the globalisation of capitalism ought to increase the wealth and living standards of all involved. However, in order for all to be involved, they must be of value to that economy. That the world lives largely in poverty means that the more the economy incorporates cheap labour, the lower the returns to
