Gas turbines are widely used for aircraft propulsion, land-base power generation, and other industrial applications like trains, marines, automobiles, etc. To satisfy the fast development of advanced gas turbines, the operating temperature must be increased to improve the thermal efficiency and output work of the gas turbine engine. However, the heat transferred to the turbine blade is substantial
The results from bending tests on 107 laminated, green-glued, beams manufactured from Norway spruce side boards are presented. The beams were made by face gluing 21-25 mm thick boards using a commercial one-component moisture curing polyurethane adhesive. In addition to the bending test results, results from shape stability measurements after climatic cycling and bond line strength and durabili
Different phenomena such as complex flow field and heat release by combustion are involved in the heat transfer process in combustion chambers. This paper concerns prediction of heat load and wail temperature in a gas turbine combustor by taking different phenomena into account. Two dimensional axi-symmetric models were used to model the flow field and combustion in a premised combustor with two d
In pre-industrial society, choosing a marriage partner was a crucial process, and especially so for landowners. This study focuses on social aspects of mate selection in five rural parishes in southern Sweden between 1829 and 1894, using an individual-level database containing information on a large number of marriages and the social origins of the marrying couple regardless of whether they were b
The highly specific relationships between parallel fiber (PF) and climbing fiber (CF) receptive fields in Purkinje cells and interneurons suggest that normal PF receptive fields are established by CF-specific plasticity. To test this idea, we used PF stimulation that was either paired or unpaired with CF activity. Conspicuously, unpaired PF stimulation that induced long-lasting, very large increas
A simple selective supercritical fluid extraction (SFE) method was developed for the determination of desorption behaviour of PCBs in sediments. This method was applied to determine the distribution of individual PCB congeners among sites of differing bonding strengths in two Swedish sediments (Lake Järnsjön and Baltic bay Orserumsviken). Four different PCB fractions were distinguished in each sed
A dosimeter gel, based on an agarose gel infused with a ferrous sulphate solution and evaluated in a magnetic resonance scanner, was used for complete verification of calculated dose distributions. Two standard treatment procedures, treatment of cancer in the urinary bladder and treatment of breast cancer after modified radical mastectomy, were examined using pixel-by-pixel and dose volume histogr
Customers have become very sensitive regarding the innovative evaluation of servicesDue to competition in the hospitality industry, it is a challenge for hotel marketers to understand customers’ behavior. There is scant research in the hotel industry of Pakistan and especially on boutique hotels. This research seeks to measure the relationship between substantive, communicative elements of the sus
OBJECTIVES: The overall aim of this study is to gain greater knowledge about the risk of suicide among suicide attempters in a very long-term perspective. Specifically, to investigate possible differences in clinical risk factors at short (≤5 years) versus long term (>5 years), with the hypothesis that risk factors differ in the shorter and longer perspective. DESIGN: Prospective study with regist
PurposeThe purpose of this paper is to explore if the application of a framework building on organisational learning focusing on organisational processes can increase our understanding of how hybrid organisation develops over time and why they fail to live up to external expectations.Design/methodology/approachThe aim of this study is descriptive and explorative. It is accordingly designed as a qu
Recent studies have reported a very high frequency of noncoagulating milk in Swedish Red cows. The underlying factors are not fully understood. In this study, we explored rennet-induced coagulation properties and relative protein profiles in milk from native Swedish Mountain and Swedish Red Polled cows and compared them with a subset of noncoagulating (NC) and well-coagulating (WC) milk samples fr
The semiarid Punata alluvial fan is located in the central part of Bolivia. The main activity of this region is the extensive agriculture, and groundwater is the main water supply. Local villagers who use groundwater reported that in some places groundwater has a salty taste. In order to investigate the origin of this problem, several TEM soundings were performed in the study area, and they were c
Formalization, understood as gaining legal status to develop their businesses, is the mainstream policy to regulate the work of street vendors in most cities in the world. However, formalization policies are criticized by different scholars, and many vendors go back to the streets after formalization despite government efforts. To contribute to this long-standing debate, this chapter explores the
In this work, we report on the efficient removal of heavy metal ions with nanostructured lithium, sodium and potassium titanates from simulated wastewater. The titanates were obtained via a fast, easy and cost effective process based on extraction of sulfate ions from the crystals of titanyl sulfate and their replacement with hydroxyl groups of NaOH, LiOH and KOH solutions leaving the Ti-O framewo
This study explores the experiences and reflections of staff in intellectual disability (ID) services concerning ageing with ID. Qualitative interviews were conducted with 24 staff members in group homes and daily activity centres. The findings showed that the staff were uncertain about the signs of ageing in people with intellectual disabilities; they compared the life conditions of these people
We have studied the dissociation of the trifluoromethane molecule, CHF3, into negative ionic fragments at the C 1s and F 1s edges. The measurements were performed by detecting coincidences between negative and positive ions. We observed five different negative ions: F−, H−, C−, CF−, and F2 −. Their production was confirmed by the analysis of triple coincidence events (negative-ion/positive-ion/pos
The Spanish fiscal system underwent profound reforms between 1977 and 1986, in close connection to the transition from dictatorship to democracy. These were meant to bring the country towards the welfare state model of its European neighbours. Some practical results in terms of progressivity and redistribution, however, were not outstanding, and inequality did not significantly decrease after demo
