Purpose - The purpose of this paper is to carry out a numerical investigation to study forced convection for a tube with fins on the inner and outer surfaces with water as the base fluid and adding particles of CuO to have a nanofluid. Design/methodology/approach - Three geometries are designed by using Solid Works and the number of inside fins is 20 with height 6 mm and thickness 1mm. The number

Ett antal superkontinenter har existerat under jordens 4.6 Ga ( miljarder år gamla ) historia. Utav dessa är superkontinenten Pangea, som betyder ”allt land”, den senaste och mest väldefinierade. Bildning och uppsprickning av superkontinenter drivs av plattektoniska processer som i sin tur beror på strömningar ( konvektion ) i jordens mantel. Förutom dessa processer så anses numera mantelplymer haEarth history is punctuated by a series of events of supercontinent amalgamation and break-up. Fragments of old continents display rifted margins and orogenic sutures that testify their involvement in supercontinent cycles. Periods of break-up are associated with widespread magmatism due to extensional thinning and rifting of the lithosphere and in some instances the arrival of mantle plumes. Mant

Aim: To explore improvement facilitators' experiences of handling their commission to implement evidence-based practice in elderly care for frail older persons. Background: Improvement facilitators were put in place across Sweden in a time-limited project by the government, with one part of the project being to evaluate the model before establishing this facilitation of evidence-based practice in

Aims: The study investigated whether people with mobility disability (MD) and/or obesity had higher job strain than people without it, and whether social support at work modifies this association. Methods: The study included 35,160 individuals (25-64 years of age) from the Stockholm Public Health Surveys of 2006 and 2010. Data on MD and obesity (BMI ≥ 3/4 30 kg/m2 calculated from weight (kg) and h

Antiglomerular basement membrane (GBM) disease is known as a super-acute proliferative glomerulonephritis caused by auto-antibodies targeting the NC1 domain of the α3 chain of type IV collagen.Here, we describe a case of atypical anti-GBM disease presenting as a dialysis-dependent acute renal failure with unusual mild glomerular involvement. We found that immunoglobulin G (IgG) deposits were restr

Government agencies in Sweden are experiencing a communicative turn where notions concerning branding, image and identity have become standardized tools and concerns. Public relations, with its focus on persuasion and creating relations with external actors, is part of this communicative turn. This book is concerned with how government agencies practice political public relations in a more communi

Slight differences, which appear in the individual animals of the same species and population have been recognised and appreciated ever since Darwin. These consistent intra-specific differences in animals have been considered very important because they are often inherited, and thus, provide the basic material for evolution to act on. This applies also to behavioural characteristics, and thus, to

Current models for the growth of Fennoscandia, including the eastern part of the Sveconorwegian Province, are largely based on U-Pb data and do not discriminate between juvenile and reworked crust. Here we present new combined U-Pb and Hf isotopic data, from the Eastern Segment and the Idefjorden terrane of the Sveconorwegian Province, and suggest a revised model of crustal growth. Most of the cry

The geochemistry of the metavolcanic rocks from the Granjeno Schist in northeastern Mexico indicates an origin in different tectonic environments: mid-ocean ridge and ocean island. High ratios of Hf/Th and Th/Nb (4.4-14 and 0.08-0.15), low ratios of LaN/YbN and LaN/SmN (0.74-1.7 and 0.60-1.4) and depleted LREE patterns in metabasalt display mid-ocean ridge characteristics. In contrast, the pattern

Late Cenozoic granitoids are widespread in a 1600km long belt forming the Western and Northern Sulawesi tectono-magmatic provinces. They can be divided into three rock series: shoshonitic (HK), high-K felsic calc-alkaline (CAK), and normal calc-alkaline to tholeiitic (CA-TH). Representative samples collected from eleven plutons, which were subjected to petrography, major element, trace element, Sr

In sensor network applications with low traffic intensity, idle channel listening is one of the main sources of energy waste.The use of a dedicated low-power wake-up receiver (WRx) which utilizes duty-cycled channel listening can significantlyreduce idle listening energy cost. In this thesis such a scheme is introduced and it is called DCW-MAC, an acronym forduty-cycled wake-up receiver based medi

Proteiner är några av livets beståndsdelar. Komplexa molekyler som förser våra kropparmed både struktur och funktion, bland annat i muskler. De är kedjor av aminosyror,som vartefter de skapas i kroppen ofta veckar sig till en specifik tredimensionell strukturför att kunna utföra den funktion de har optimerats för under evolutionens gång.Uppstår fel i denna process kan felaktiga strukturer, som oftA protein chain often folds into a functional, specific three dimensional structure. Failurein this process can in some cases lead to disease, e.g. the misfolding disease ALS. Themechanisms behind the folding has mostly been studied under dilute conditions. However,in the natural cellular environment of proteins, the concentration of macromolecules is highand it is believed that this affects vario

OBJECTIVE: To evaluate the measurement variability of quantitative sensory testing (QST) in persons with post-stroke shoulder pain. DESIGN: A test-retest design. PARTICIPANTS: Twenty-three persons with post-stroke shoulder pain (median age 65 years).METHODS: Thermal detection thresholds (cold and warm), pain thresholds (cold and heat) and mechanical pain thresholds (pressure and pin prick) were as

A number of biological systems have been studied in the past in an attempt to find the underlying cause of anxiety and depression. The main aim of the work described in this thesis was to investigate the importance of inflammation and the renin-angiotensin-aldosterone system (RAAS) in relation to anxiety and depression. The methods used ranged from studying patients to preclinical animal experimen

Polyelectrolyte adsorption and polymer mediated interactions in different colloidal polymer systems have been studied in this work. Theoretical methods and experimental techniques are combined, in order to obtain more general reliable results, as well as a deep understanding of the molecular mechanisms that are responsible for the observed behaviors. Two different types of highly charged cationic

Zero Magic is a trick for the financial markets, which has the capacity to undermine the perceived value of a publicly traded company and profit from this. Short selling is a way of profiting from loss: Making money if and when a target company loses in value. It is a fundamental market activity that goes as far back as the first stock, yet to this day little is publicly known about the strategie

Transition to adulthood, referring to the process of moving from childhood to adulthood, can be a complex period for youths with disabilities who might need special support transitioning into an independent life as adults. Caregivers are significant persons for the youths, which is why their own health and wellbeing is important. Therefore the overall aim of this thesis was to gain a deeper unders

Popular Abstract in English Soil as an ecosystem is a reservoir for several living organisms including microorganisms, earthworms, collembolans, nematodes and protozoans. They are involved in cycling the nutrients through degrading the organic compounds (source of carbon essential for all living organisms) like plant residues and respire part of it as carbon dioxide. Organic compounds get stored iAbstract Intensive land use in agriculture can lead to higher loss of biodiversity in soils and subsequently carbon due to tillage and application of pesticides and fertilizers. The microbial communities are pivotal to ecosystem processes in soil such as nutrient cycling, soil formation and plant productivity and thus are affected by land use. The main aim of this thesis is to understand the effe
