Using spectra of RR Lyrae stars in the Small Magellanic Cloud (SMC) a metallicity snapshot from an early epoch in the history of the SMC could possibly be obtained. The SMC, one of our closest neighbours in the Local Group of galaxies, offers the opportunity to study another galaxy close-up. The history of the SMC can be traced using the chemical characteristics of its different generations of sta
E-waste is one of the fastest growing waste streams in India due to an increase in consumption from businesses and domestic users. There is no separate law on e-waste management in India and it is presently interpreted under the Hazardous Waste (HW) rules. In practice, e-waste is largely handled by people in the informal sector. Having recognized the need for a separate policy on e-waste managemen
Sedan tillkomsten av den nuvarande rättegångsbalken på 1940-talet har utgångspunkten i svensk rätt varit att bevisprövningen ska vara fri och inte styrd av legala normer. Detta hindrade emellertid inte lagstiftaren från att i förarbetena ställa upp krav på att bevisprövningen skulle vara objektiv och analytisk. Som en följd därav utvecklades ett antal bevisprövningsmetoder i den juridiska doktrine

Small oligomers formed early in the process of amyloid fibril formation may be the major toxic species in Alzheimer's disease. We investigate the early stages of amyloid aggregation for the tau fragment AcPHF6 (Ac-VQIVYK-NH2) using an implicit solvent all-atom model and extensive Monte Carlo simulations of 12, 24, and 36 chains. A variety of small metastable aggregates form and dissolve until an a
Bone morphogenetic proteins (BMPs) are pleiotropic secreted proteins, structurally related to transforming growth factor (TGF)-beta and activins. BMPs play pivotal roles in the regulation of embryonic lung development and branching of airways and have recently been considered to influence inflammatory processes in adults due to their chemotactic activity on fibroblasts, myocytes, and inflammatory
Denna uppsats har haft som syfte att undersöka gällande rätt med avseende på nödvärnsrättens utformning i svensk, dansk, norsk och engelsk rätt. Genom en rättsdogmatisk metod redogörs för lagtext, förarbeten, doktrin och relevant praxis på området, vilket är i enlighet med de utpekade rättskällorna inom rättskälleläran. Rätten till nödvärn i svensk rätt regleras i BrB 24 kap. 1 § och utmärks av aThe main purpose of this paper is to describe the law regarding the right of self-defense in Sweden, Denmark, Norway and England. Using a legal dogmatic method, it intends to describe the rights and possibilities being approved for a civilian in self-defense when being unrightfully attacked. This paper will also describe established law and analyze the right of self-defense as applicable in case l
To assess the value of ECG-gating for the diagnosis of myocardial infarction using myocardial perfusion scintigraphy (MPS) and an artificial neural network. A total of 422 patients referred for MPS were studied using a one day Tc-99m-tetrofosmin protocol. Adenosine stress combined with submaximal dynamic exercise was used. The images were interpreted by one of three experienced clinicians and thes
Motivation: The above-ground tissues of higher plants are generated from a small region of cells situated at the plant apex called the shoot apical meristem. An important genetic control circuit modulating the size of the Arabidopsis thaliana meristem is a feed-back network between the CLAVATA3 and WUSCHEL genes. Although the expression patterns for these genes do not overlap, WUSCHEL activity is
Ett omdebatterat ämne inom svensk rätt är på vilket sätt de så kallade utnyttjandefallen, då gärningsmannen utnyttjat att en person befunnit sig i en särskilt utsatt situation (tidigare hjälplöst tillstånd), regleras i svensk rätt. Frågan huruvida den svenska, tvångsbaserade våldtäktslagstiftningen ger ett heltäckande skydd i dessa situationer, eller om en samtyckesreglering bör införas har diskut
A general introduction to the use of feed-back artificial neural networks (ANN) for obtaining good approximate solutions to combinatorial optimization problems is given, assuming no previous knowledge in the field. In particular we emphasize a novel neural mapping technique which efficiently reduces the solution space. This approach maps the problems onto Potts glass rather than spin glass models.
Background How DNA repair enzymes find the relatively rare sites of damage is not known in great detail. Recent experiments and molecular data suggest that individual repair enzymes do not work independently of each other, but interact with each other through charges exchanged along the DNA. A damaged site in the DNA hinders this exchange. The hypothesis is that the charge exchange quickly libera
All higher functions of the cell are dependent on cell signaling. It is the way of the cell to obtain information about the world surrounding it. By getting information on e.g. temperature, glucose concentrations, or the density of neighboring cells, the cell can make decisions on how to optimally act given the supplied information. Even though cells are very different, some of the basic mechanism
Metalliciteten hos en stjärna är den del av materien som inte består av helium eller väte. Detta innebär att när en astronom talar om metallicitet, inkluderar hon även icke-metalliska grundämne, såsom kol, syre eller något av de tyngre grundämnena. Genom att studera metalliciteten hos en stjärna kan vi lära oss en del om dem, till exempel dess ålder och ursprunget för var våra grundämnen kommer if
In this thesis we study the width of the Higgs boson in the process pp → t ̄t 4l at LO using MadGraph5_aMC@NLO to generate the events. The contributions including the Higgs signal, continuum background and interference were considered in order to calculate the expected number of events in a broad range of four-lepton invariant masses. Due to strongly enhanced off-shell contributions an upper bound
The width of the Higgs boson is a quantity that cannot be measured directly from the on-shell Higgs peak; it would have to be measured indirectly. In 2013, Caola and Melnikov developed a method to determine the Higgs width by using off-shell and on-shell cross-sections and applying the narrow-width approximation. In this thesis, we will use the indirect method of finding the Higgs width for the pr
