Purpose: This study aims to clarify the mechanism of film hole location at the span-wise direction of an internal cooling channel with crescent ribs on the adiabatic film cooling performance, three configurations are designed to observe the effects of the distance between the center of the ellipse and the side wall(Case 1, l = w/2, Case 2, l = w/3 and for Case 3, l = w/4).

Importance: Soft drinks are frequently consumed, but whether this consumption is associated with mortality risk is unknown and has been understudied in European populations to date.Objective: To examine the association between total, sugar-sweetened, and artificially sweetened soft drink consumption and subsequent total and cause-specific mortality.Design, Setting, and Participants: This populatio
Purpose: The purpose of this study is to enhance the thermal performance in the labyrinth channel by different ribs shape. The labyrinth channel is a relatively new cooling structure to decrease the temperature near the trailing region of gas turbine. Design/methodology/approach: Based on the geometric similarity, a simplified geometric model is used. The k − ω turbulence model is used to close th
Ethics is the study of the normative dimensions of human relations and experiences. This chapter discusses such questions in relation to basic values in modern society. The normative foundations for the analysis are the values of human dignity, autonomy, freedom, equality, and solidarity, as well as the responsibilities of society toward its citizens, including freedom, security, and justice. The
Upon ischaemic stroke, brain-resident and peripheral immune cells accumulate in the central nervous system (CNS). Interestingly, these cells express pattern specific to neurotransmitter receptors and, therefore, seem to be susceptible to neurotransmitter stimulation, potentially modulating their properties and functions. One of the principal neurotransmitters in the CNS, dopamine, is involved in t
Purpose: The study aims to focus on rotation effects on a ribbed channel of gas turbine blades for internal cooling. The combination and interaction between secondary flows generated by angled rib geometry and Coriolis forces in the rotating channel are studied numerically. Design/methodology/approach: A radially outward flow passage as an internal cooling test model with and without ribs is used
The objective of this study is to describe a completely new 10-day gross primary production (GPP) product (MGPP LSA-411) based on data from the geostationary SEVIRI/MSG satellite within the LSA SAF (Land Surface Analysis SAF) as part of the SAF (Satellite Application Facility) network of EUMETSAT. The methodology relies on the Monteith approach. It considers that GPP is proportional to the absorbeThe objective of this study is to describe a completely new 10-day gross primary production (GPP) product(MGPP LSA-411) based on data from the geostationary SEVIRI/MSG satellite within the LSA SAF (Land SurfaceAnalysis SAF) as part of the SAF (Satellite Application Facility) network of EUMETSAT.The methodology relies on the Monteith approach.

Governance of common resources such as water calls for rethinking structure, legal frameworks and property rights. In order to promote the decentralization of water governance, Water User Associations (WUAs) were created in many countries, such as India and Turkey, to operate and maintain irrigation systems as well as take over the responsibility of water distribution among water users. Despite pr
Denna artikel beskriver den bokutgivning som skedde inom ramen för tidskriften Zenit mellan åren 1968 och 1982. Zenit gav ut böcker i egen regi men redigerade också tre bokserier på Bo Cavefors förlag(två st.) och på Raben & Sjögren (1). Böckerna gavs typografisk form av Leif Thollander. Tidskriftens Zenits bakgrund i den ""nya vänstern"" skisseras. Bokutgivningens innehåll och karaktär beskri
Purpose: The fluid flow in a rotating channel is obviously different from that in a stationary channel due to the existence of Coriolis force, which, in turn, enhances the heat transfer on the trailing side and reduces the heat transfer on the leading side. The purpose of this paper is to study various rib configurations combined with channel orientation on heat transfer and frictional loss in a r
Background: Residential care homes (RCHs) are increasingly becoming a common place of death for older people. Aim: The aim of this study was to describe family members' experiences of care of the dying in RCHs where the Liverpool care pathway for the dying patient was used. Methods: This study had a descriptive qualitative study design. Fifteen (n=15) individual interviews were analysed using qual
This study documents the advancement of laying dates in three species of tits (Paridae) in southernmost Sweden during recent decades, and the absence of a similar response in the pied flycatcher Ficedula hypoleuca. It is based on several different nestbox studies; the oldest one starting in 1969. During 1969 to 2012, mean spring temperatures in the study area increased by between 0.06 and 0.08 °C This study documents the advancement of laying dates in three species of tits (Paridae) in southernmost Sweden during recent decades, and the absence of a similar response in the pied flycatcher Ficedula hypoleuca.

Objectives Biologic agents have dramatically changed treatment of rheumatoid arthritis (RA). To date only scarce head-To-head data exist especially when the biological therapies are given as monotherapy without concomitant disease modifying drugs (DMARDs). Thus the objective of the current study is to evaluate treatment response of all available biological therapies with special focus on utility (
Inom beredskapen mot radiologiska och nukleära olyckor och katastrofer spelar strålningsmätningar en avgörande roll för att ta reda på vad som har hänt och hur farligt det är för människa, djur och natur och på vilket sätt det påverkar miljö och samhällsfunktioner. I Sverige och många andra länder i världen har allmänheten en rättighet att få reda på vad som hänt och vad de utsätts för i ett eventThis thesis describes investigations made on mobile and stationary gammaspectrometry made both under laboratory conditions and in situ. The objective hasbeen to identify and quantify radionuclides in the form of point sources,contamination and widespread deposition in situations where the measurementgeometry is not known beforehand. Both scintillators and semiconductor detectors ofsimilar size wer
How can the realities of global warming be made visible in literary texts? After the rise of 'cli-fi', it might be time to return to a trove of literature written long before the discoveries of climate science: fiction about fossil fuels. It is filled with premonitions of disasters, such as extreme heat and terrible storms. Focusing on two texts - Ghassan Kanafani's Men in the Sun and Joseph Conra
Nowadays, transition metal oxide catalysts are employed to a large extent in many chemical processes for the selective production of chemicals and intermediates. Although metal oxides are mostly known as oxidation catalysts, they can successfully catalyze a wide range of reactions, such as dehydration. Two different processes have been studied in the present work: the selective oxidation of methan
