A 2.0-million-year-old shallow-submarine sedimentary deposit on Milos Island, Greece, harbours an unmetamorphosed fossiliferous iron formation (IF) comparable to Precambrian banded iron formations (BIFs). This Milos IF holds the potential to provide clues to the origin of Precambrian BIFs, relative to biotic and abiotic processes. Here, we combine field stratigraphic observations, stable isotopes
Hemicelluloses, which are abundant in nature and have potential use in a wide variety of applications, may make an important contribution in helping relieve society of its dependence on petrochemicals. However, cost-efficient methods for the isolation of hemicelluloses are required. This article presents an economic evaluation of a full-scale process to isolate hemicelluloses from process water fr
The electron transport properties of photosystem II (PSII) from five different domains of the thylakoid membrane were analyzed by flash-induced fluorescence kinetics. These domains are the entire grana, the grana core, the margins from the grana, the stroma lamellae, and the Y100 fraction (which represent more purified stroma lamellae). The two first fractions originate from appressed grana membra
This article proposes several improvements to an adaptive fingerprint enhancement method that is based on contextual filtering. The term adaptive implies that parameters of the method are automatically adjusted based on the input fingerprint image. Five processing blocks comprise the adaptive fingerprint enhancement method, where four of these blocks are updated in our proposed system. Hence, the
Popular Abstract in Swedish Produkter bestående av polymera material produceras i allt större omfattning. Materialen används därför i fler tillämpningar där deras specifika egenskaper kommer till användning. Materialens förmåga att modifieras för att passa en specifik tillämpning motiverar materialgruppens ökade betydelse. Idag används polymera material mer eller mindre i alla branscher t.ex. tran
The work presented in this dissertation is concerned with the microstructures and surface roughness of test slabs of Ti-6Al-4V produced by one of powder based Additive Manufacturing (AM) technique namely electron beam melting (EBM). The effects of process parameters of a EBM system and geometry factors of a EBM build such as slabs’ thickness and height etc. on the microstructure and the surface ro
A general expression containing all the divergences in Chiral Perturbation Theory at one loop for anomalous processes has been calculated. The nonrenormalization of some amplitudes (Adler-Bardeen theorem) is observed. The different types of corrections are identified. The contributions from vector meson exchange are determined for all anomalous processes. Explicit cancellation of divergences is sh
We focus on the problem of semantic segmentation based on RGB-D data, with emphasis on analyzing cluttered indoor scenes containing many visual categories and instances. Our approach is based on a parametric figureground intensity and depth-constrained proposal process that generates spatial layout hypotheses at multiple locations and scales in the image followed by a sequential inference algorith
BACKGROUND: How long one lives, how many years of life are spent in good and poor health, and how the population's state of health and leading causes of disability change over time all have implications for policy, planning, and provision of services. We comparatively assessed the patterns and trends of healthy life expectancy (HALE), which quantifies the number of years of life expected to be liv
Differential alterations of the spliceosomal Uridylic acid rich small nuclear RNAs (UsnRNAs) (U1, U2, U4, US, and U6) are reported to be associated with cellular proliferation and development, but definitive information is scarce and also elusive. An attempt is made in this study to analyze the metabolic patterns of major spliceosomal UsnRNAs, during tumor development, in an in vitro carcinogenesi
Background: Preterm birth is known to constitute the major risk factor for development of germinal matrix-intraventricular hemorrhage (GM-IVH). Head position may affect cerebral hemodynamics and thus may be involved indirectly in development of GM-IVH. Turning the head toward one side may functionally occlude jugular venous drainage on the ipsilateral side while increasing intracranial pressure an
Mobility constitutes an important aspect in order to create quality of life, where a well working public transportation can decrease the level of stress and create more “flow” in the everyday life (Atkins 2009). However, not all individuals have the mobility prerequisites; for people with disabilities, the preconditions of movement are limited. The purpose of this thesis is to examine the accessi
Syftet med denna uppsats är att undersöka de för parfymtillverkare tillgängliga varumärkes- och marknadsrättsliga verktygen mot snålskjutsfenomenet ”smell-alikes”, dvs. efterbildningar av välkända märkesparfymer av lägre kvalitet som säljs för en bråkdel av originalpriset. I avsaknad av ett självklart, juridiskt varumärkesskydd för dofter lämnas producenterna att förlita sig på det varumärkesrätThe aim of this paper is to investigate the legal tools available for perfume producers in trademark and market law against the free-riding phenomenon “smell-alikes”, i.e. imitations of famous brand perfumes of lower quality sold at a fraction of the original price. In the absence of evident legal trademark protection for fragrances, manufacturers have to rely on the trademark protection granted
Eld är en av de viktigaste störningsprocesserna som påverkar den terrestra biosfären genom att forma vegetationens spridning, komposition, struktur, växtdiversitet och biokemiska cykler. Några av de mest påverkade ekosystemen är våt-torra områden, här klassificerade som savann eller Medelhavsområden. Denna påverkan kan studeras på olika sätt, antingen genom ett långvarigt och fortlöpande experimenFire is one of the most important disturbance processes affecting the terrestrial biosphere, altering the vegetation composition and distribution, structure, plant diversity and biogeochemical cycles. Some of the most influenced ecosystems are wet-dry areas, here classified as savannah or Mediterranean regions. The influence can be studied in different ways, either by long-term experiments like th
Syftet med studien var att analysera den kringliggande problematiken för energiproducenters beslutsfattningsprocess när de utvärderar investeringar i energieffektiviseringsåtgärder för uppvärmningssystem i vattenkraftsbaserade produktionsenheter i Sverige. Studien har utgått ifrån de dokumenterade barriärerna för investeringar i energieffektiviseringsåtgärder och applicerar konceptet om EnvironmenThe purpose of this study was to analyze the problems surrounding the decision making process for a energy producer when dealing with (potential) energy efficiency measures. This work creates the basis of a investment prioritizing structure directed at heating systems within Swedish hydro power based production facilities managed by Vattenfall. The research was called for by Vattenfall, as the org
In this paper a dialectic complexity framework is presented and reflected upon. The purpose of the framework is to guide researchers and practitioners in rethinking and reframing underlying assumptions, and address how these have a possible influence and impact on researchers’ and practitioners’ processes of making sense, understanding, explaining, improving etc. aspects of different types of issu
