Flat plate solar collectors (FPSCs) are the most often used as solar collectors due to their easiness of installation and usage. The current research investigates the energy efficiency of FPSC using different mass concentration with varied base fluids containing Graphene nanofluids (T-Gr). Mass concentration of 0.1%-wt., 0.075%-wt., 0.050%-wt. and 0.025%-wt. were mixed with ethylene glycol (EG) an

BACKGROUND: The postoperative complication rate is 30-64% among patients undergoing muscle-invasive and recurrent high-risk non-muscle-invasive bladder cancer surgery. Preoperative risky alcohol use increases the risk. The aim was to evaluate the accuracy of markers for identifying preoperative risky alcohol.METHODS: Diagnostic test sub-study of a randomized controlled trial (STOP-OP trial), based

Middle-aged adults engaging in unhealthy lifestyle behaviors are at higher risk of chronic diseases. However, little is known about the co-occurrence of these behaviors and their determinants. This cohort study examined the co-occurrence of unhealthy lifestyle behaviors (alcohol consumption, diet, physical inactivity, and smoking) in 30,154 middle-aged adults and their associations with sociodemog

To examine whether the level of genetic risk in psychiatric disorders impacts the social functioning of affected individuals, we examine the relationship between genetic risk factors for major depression (MD), anxiety disorders (AD), bipolar disorder (BD), non-affective psychosis (NAP), alcohol use disorder (AUD), and drug use disorder (DUD) in disordered individuals and five adverse social outcom

Jet quenching is the process of color-charged partons losing energy via interactions with quark-gluon plasma droplets created in heavy-ion collisions. The collective expansion of such droplets is well described by viscous hydrodynamics. Similar evidence of collectivity is consistently observed in smaller collision systems, including p p and p + Pb collisions. In contrast, while jet quenching is ob

Externally bonded fiber-reinforced polymer (FRP) plates or sheets have become a common retrofitting approach for sustaining old reinforced concrete structures in the modern era. The capacity of FRP-strengthened structures cannot be accurately estimated because the bond strength between FRP and concrete surface is accurately unpredictable. Various studies are available in the literature to predict

A phytochemical investigation of Curcuma zedoaroides rhizomes resulted in the isolation of ten sesquiterpenes (1–10) and two diterpenes (11−12). The structure of compounds 1–12 was identified as phaeocaulisin E (1), zedoarondiol (2), isozedoarondiol (3), isoprocurcumenol (4), neoprocurcumenol (5), procurcumenol (6), 1-epi-procurcumenol (7), aerugidiol (8), curcumenol (9), curcumenone (10), curcumi

Even among the most irradiated gas giants, so-called ultra-hot Jupiters, KELT-9b stands out as the hottest planet thus far discovered with a dayside temperature of over 4500 K. At these extreme irradiation levels, we expect an increase in heat redistribution efficiency and a low Bond albedo owed to an extended atmosphere with molecular hydrogen dissociation occurring on the planetary dayside. We p

Accurate characterization of large-scale antenna arrays is growing in importance and complexity for the fifth-generation (5G) and beyond systems, as they feature more antenna elements and require increased overall performance. The full 3D patterns of all antenna elements in the array need to be characterized because they are in general different due to construction inaccuracy, coupling, antenna ar

The aim of this study was to investigate how gender norms are represented in formal court decisions regarding the taking into compulsory care of young persons according to 3§ LVU (Care of Young Persons Special Provisions Act). The empirical material consisted of 30 court cases, whereof 15 cases concerned girls and 15 concerned boys. The method used was a qualitative content analysis. This method f

En våtmarks kapacitet – går det att optimera en våtmark för att minska såväl eutrofiering som brunifiering? Att använda en våtmark i syfte att minska såväl övergödning som brun missfärgning av vattendrag, är absolut möjligt, men hur och varför är frågor som behöver studeras mer grundligt. Däremot verkar placeringen i landet i kombination med våtmarkens procentuella storlek i förhållande till avrDue to changes in land use, as well as impacts from the climate change, our inland waters are now exposed to problems such as eutrophication and brownification. This complicates management to develop clean drinking water, as well as it leads to anoxic bottoms and reduces primary production. This literature review aims to see if wetlands can work as a natural filter to reduce both nutrients (nitrog

Background:The research of social science tends in many cases lean towards an approach that focus on negatively influencing factors, rather than health promoting factors from a salutogenic perspective. In the field of criminology, this approach commonly investigates reasons behind criminal behavior instead of studying the salutogenic factors, i.e. reasons why people do not engage in a criminal lif

An evaluative neutralisation process, whereby questionnaire items are phrased to be less evaluative, was used to create a new less socially desirable version of the social dominance orientation scale (SDO7). The main goal is to counteract the persistent floor effect which has affected the scale since its inception. The rationale behind the suggested correction is rooted with the problem of social

Denna studie sökte svar på huruvida människor tenderar att känna mer empati för personer som tillhör deras politiska ingrupp än de som befinner sig i utgruppen, och därmed om empati är selektivt i förhållande till politiska in- och utgrupper. Empati definieras här som (1) kognitiv empati, (2) affektiv empati, och (3) empatisk oro. Urvalet bestod av personer som identifierar sig som socialdemokrateThis study sought to answer whether people have a higher tendency to feel empathy towards people who are part of their own political ingroup, rather than those who are in the outgroup, meaning, if empathy is selective in relation to political in- and outgroups. Empathy is defined here as (1) cognitive empathy, (2) affective empathy, and (3) empathic concern. The sample consisted of people who symp

Med en befolkning på cirka 30 miljoner människor är kurderna den fjärde största etniska gruppen i Mellanöstern. Trots detta har kurderna inte sin egen självständiga stat vilket gör dem till en minoritetsgrupp i Turkiet, Irak, Iran och Syrien. Eftersom kurderna är utspridda över fyra olika stater är det av intresse att undersöka hur de hänvisar till varandra i förhållande till idén om att ha en suvWith a population of around 30 million people, the Kurds are the fourth largest ethnic group in the Middle East. Despite this, the Kurds do not have their own independent state which makes them a minority group in Turkey, Iraq, Iran and Syria. Since the Kurds are scattered over four different states it is of interest to examine how they refer to each other in relation to the idea of having an inde
