The main aim of this paper is to study land-atmosphere exchange of carbon dioxide (CO2) for semi-arid savanna ecosystems of the Sahel region and its response to climatic and environmental change. A subsidiary aim is to study and quantify the seasonal dynamics in light use efficiency (epsilon) being a key variable in scaling carbon fluxes from ground observations using earth observation data. The n

To account for microbial reduction and food quality changes, first-order chemical reaction was added to a model for axial-dispersed plug flow (ADPF), which was recently developed for efficient (In the terminology of this paper, efficient is related to computation time for a given level of accuracy.) computation of time-dependent, large flow systems. It was shown that the extended ADPF model gives

There exists an increasing demand for cost and time efficient cutting tests for describing the performance of different combinations of cutting tools and workpiece materials in the cutting process both in industry and academia. Cutting tools are expected to withstand the heat and the pressure developed during the machining of difficult to machine materials such as Ti6Al4V. This article introduces

The far-infrared absorption spectra have been recorded for hydrogen-bonded complexes of water with methanol and t-butanol embedded in cryogenic neon matrices at 2.8 K. The partial isotopic substitution of individual subunits enabled by a dual inlet deposition procedure provides for the first time unambiguous assignments of the intermolecular high-frequency out-of-plane and low-frequency in-plane d

Hitherto unobserved long-lived massive particles with electric and/or colour charge are predicted by a range of theories which extend the Standard Model. In this Letter a search is performed at the ATLAS experiment for slow-moving charged particles produced in proton-proton collisions at 7 TeV centre-of-mass energy at the LHC, using a data-set corresponding to an integrated luminosity of 34 pb(-1)

This paper is based on a new procedure for dynamic output feedback design for systems with nonlinearities satisfying quadratic constraints. The new procedure is motivated by the challenges of output feedback control design for the 3-state Moore-Greitzer compressor model. First, we use conditions for stability of a transformed system and the associated matching conditions to find the data of the st

Background The clinical distinction between Alzheimer's disease (AD) and dementia with Lewy bodies (DLB) is sometimes difficult, particularly in mild cases. Although CSF markers such as amyloid beta 42 (A beta 42) and P-tau can distinguish between AD and normal controls, their ability to distinguish between AD and DLB is not adequate. Objective This study aims to investigate whether CSF markers, i

Energy efficiency improvements have not yet been developed to their full potential. Further improvements are necessary to tap into the full potential of reducing greenhouse gas emissions by decreasing energy consumption. This challenge is particularly relevant in buildings, a sector that consumes substantial amounts of energy. Despite numerous public policies to increase the energy efficiency perf

Indoor air pollution is a problem of great concern, estimating to cause around 2 million premature deaths, with 400.000 cases suspected to happen in Sub-Saharan Africa. In this thesis, indoor air pollution emissions associated with the Ethiopian traditional coffee ceremony has been studied as a model for cooking exposure. Coffee preparation is a ceremony which is conducted in almost every Ethiopia

Abstrakt Bakgrund: Psykisk ohälsa är ett av de snabbast växande hoten mot folkhälsan varav depression och ångestsjukdomar ökar mest. Forskning visar att kostvanor har ett samband med psykisk ohälsa. Distriktssköterskan möter patienter med psykisk ohälsa i sitt arbete och hälsoprevention ingår som en del i arbetet. Syftet: Syftet var att undersöka kostens betydelse för psykisk ohälsa genom att kar

Bakgrund: Befolkningens ålder ökar vilket har lett till att Världshälsoorganisationen (WHO) har utarbetat en plan för “Hälsosamt Åldrande”. I planen ingår det att medvetandegöra äldre personer om sin hälsa och främja hälsosamma levnadsvanor som motion, hälsosam kost, inget tobaks- eller alkoholbruk. Dessa åtgärder främjar äldres hälsa vilket minskar både personligt lidande och samhällskostnader. S

Up to this date, only a few silk hydrogels were reported to be injectable. Of these, none are truly biomimetic, and are instead comprised of blends with limited amounts of silk. Hence, no truly silk-based hydrogels exist as of today. From the reported injectable matrices, only a few have considered the natural progressive acidification to which silk proteins are exposed before spinning. Adding to

Människor har rätt att försvara sig själva, så kallat nödvärn, vid situationer då de blir utsatta för ett angrepp. I denna uppsats utreds hur nödvärnsrätten ser ut i Sverige och hur poliser och privatpersoner bedöms då de använt skjutvapen i självförsvar. Genom en rättsdogmatisk metod har lagstiftning, förarbeten, praxis och doktrin bearbetats för att fastställa gällande rätt. Nödvärnsrätten regIf a person gets assaulted, he or she is entitled the right to self-defense. This essay investigates the right to self-defense in Sweden and the assessments done of policemen and civilians when using weapons in self-defense. By using a legal dogmatic methodology, the material used is largely consisting of legal doctrine, literature and case law with the aim and intention to clarify how the law is

Hotet från terrorism har under 2000-talet ökat. Den 7 april 2017 blev ökningen ännu mer markant, då ett terrordåd inträffade i Stockholm. Strax efter denna händelse tillsatte regeringen en utredning för att utreda om ytterligare lagstiftning på området än den redan relativt omfattande regleringen som fanns behövdes. Utredaren kom man fram till att kriminalisering av deltagande i en terroristorganiThe threat from terrorism has during the 21st century increased. When an act of terror occurred in Stockholm on the 7th of April 2017, the threat got even more apparent. Terrorism legislation has for a long time been a well-regulated area in Swedish law, however soon after this incident the Swedish government assigned an investigation to see if further legislation in the area was required. In the

Skyddet mot angrepp på företagshemligheter regleras i lagen om företagshemligheter. I samband med att den nya lagen trädde i kraft 2018 infördes en möjlighet att hindra angrepp på företagshemligheter i förväg. Det innebär en skärpning av lagen eftersom det tidigare endast varit möjligt att hindra fullbordade angrepp från att fortsätta. Syftet med uppsatsen är att utreda den tidigaste punkten för vThe Swedish Act on trade secret protects against trade secret attacks, such as unlawful acquisition, use and disclosure of trade secrets. Since the new law entered into force 2018, the protection against trade secrets has been extended to include situations where the unlawful acquisition, use or disclosure of the trade secret is not yet carried out. The purpose of this thesis is to identify the ea

Digitalisering av ekonomin och nya digitala affärsmodeller har skapat utmaningar för det internationella skattesystemet. Organisationen för ekonomiskt samarbete och utveckling, OECD, har under de senaste åren arbetat med att ta fram förslag som kan hantera problematiken. Beskattningen av ett företag sker baserat på i vilken stat som företaget har hemvist. Enligt den nuvarande regleringen av fast dThe digitalisation of the economy has resulted in new business models that pose substantial tax challenges for the international tax system. The Organisation for Economic Co-operation and Development, OECD, has published various reports and proposals on how to address these challenges. Under the current system enterprises are taxed based on residency. However, another state may tax an enterprise i
