Mellan kulturkrig och byråkrati : Om akademisk frihet och universitetslärares professionalitet

Ett av de senaste årens mest uppmärksammade fenomen inom högre utbildning handlar om olika former av gränshållande kring potentiellt upprörande undervisningsinnehåll. Dessa konflikter har lett till intensiv mediabevakning och politisk mobilisering. Men bortom de mest uppmärksammade konflikterna finns återkommande och vardagliga situationer där frågor om exempelvis bild- och språkbruk utmanar stude

Surfactant effects on the synthesis of porous cerium oxide from a type IV deep eutectic solvent

In this work we present a novel, low temperature and green method for atom-efficient solvothermal synthesis of crystalline, micelle templated cerium IV oxide (ceria) from a type IV deep eutectic solvent (DES) comprising a hydrated cerium containing metal salt, cerium(iii) nitrate hexahydrate (Ce(NO3)3·6H2O), and a hydrogen bond donor, urea, in a molar ratio of 1 : 3.5. Self-assembled nanostructure

Production of sub-10 micrometre cellulose microbeads using isoporous membranes

The production of sub-10 µm cellulose microbeads via membrane emulsification using isoporous membranes is reported here for the first time. Poly(ethylene terephthalate) membranes, with defined interpore distances, pore diameters and straight-through pores were fabricated via photolithography. A dispersed phase of 8 wt% cellulose solution was extruded through the membrane pores, forming, due to she

Temperature dependent intercalation of molten 1-hexadecanol into Brodie graphite oxide

Intercalation of very long molecules into the structure of multi-layered graphene oxide (GO) was studied using example of 1-hexadecanol (C16), an alcohol molecule with 16 carbon atoms. Brodie graphite oxide (BGO) immersed in excess of liquid C16 just above the melting point shows expansion of c-unit cell parameter from ∼6 Å to ∼48.76 Å forming a structure with two densely packed layers of C16 mole

EMG-aktivering av rotatorcuffen vid olika muskelstärkande aktiviteter - En biomekanisk studie.

Introduction Both M. Supraspinatus and M. Infraspinatus of the rotator cuff play a role in stabilizing the shoulder during movement. When rehabilitating shoulders after injury a wide range of tools are used to strengthen the shoulder, often including a pulley system or TheraBand. According to evidence, no tool does however stand out as the most optimal one to use. Purpose The purpose of this study

Implicita och explicita attityder gentemot kvinnor En studie om sambandet mellan implicita och explicita attityder

Denna studie undersöker implicita och explicita attityder till kvinnor i Sverige och sambandet däremellan. Urvalet bestod av män och kvinnor (N = 62) i olika åldrar och yrkesbefattningar i Sverige. För att fånga deltagarnas implicita associationer användes Implicit Association Test (IAT). IAT ämnar att mäta personers automatiska och spontana implicita associationer. De explicita attityderna mättesThis study examines implicit and explicit attitudes towards women in Sweden and the connection between these. The sample consisted of men and women (N = 62) of different ages and professional positions in Sweden. To capture the participants' implicit associations, the Implicit Association Test (IAT) was used. The IAT aims to measure people’s automatic and spontaneous implicit associations. Exp

Solar air heater performance enhancement with differently shaped miniature combined with dimple shaped roughness : CFD and experimental analysis

A numerical study was carried out in a solar air heater (SAH) using different shapes of miniature (V, arc and transverse broken-miniature) combined with dimples on an absorber panel to improve heat transfer. For an experimental and simulation study using ANSYS (Fluent), a dimple with a V-miniature rib was fabricated on a plate (absorber) as a roughness element. By providing the angle of attack (α)

En jämförelse av upplevd kunskap och förekomst av skadeförebyggande träning hos aktivt fotbollsutövande manliga och kvinnliga ungdomar

Bakgrund Skador inom fotboll är vanligt förekommande, både bland män och kvinnor. Studier visar att tillämpning av skadeförebyggande träning kan minska risken för skador. Tillämpningen av skadeförebyggande träning sker inte så ofta som den kanske borde. Syfte Syftet med studien var att undersöka och jämföra upplevd kunskap och förekomst av muskelstärkande träning hos en grupp manliga och kvinnlig

Improving inorganic composition and ash fusion behavior of spruce bark by leaching with water, acetic acid, and steam pre-treatment condensate

The present study evaluates the effect of water and acetic acid washing on the chemical composition of spruce bark in-depth. Also, washing with steam explosion condensate (SEC) was investigated which is a novel attempt. The leaching kinetics of troubling elements (TE) was studied to understand the leaching behavior of TEs and for upscaling the process. Furthermore, to study the ash transformation

Formation of ordered mesoporous thin films through templating

Pores in the size range 2.0-20 nm are considered mesopores. Using the sol-gel process and a catalog of surfactant molecules, thin films with ordered mesopores can be produced. Films formed by evaporation-induced self-assembly, growth from solution, and other methods such as vapor phase deposition and pulsed laser deposition are examined. The various patterns derived from these approaches are discu

The role of phoenixin in the proliferation and migration of ectopic epithelial cells in vitro

AimEndometriosis is one of the most common gynecologic diseases in women of reproductive age. The pathophysiology of endometriosis is still not fully understood. Phoenixin (PNX-14) is a newly discovered neuropeptide that regulates the hypothalamo–pituitary–gonadal (HPG) axis and reproductive functions. Recently, we reported that PNX-14, its precursor protein and receptor were expressed in human en

TWO THEOLOGIANS AND “WHY I AM NOT A CHRISTIAN”

Bertrand Russell’s speech “Why I Am Not a Christian” (1927) triggered many theologians to defend Christian beliefs. Aside from his rational criticism of the so-called “proofs” of God’s existence, it is his humorous irony as a rhetorical weapon that made many abandon their faith in Christianity and become atheists or at least agnostics. In this article I examine two British theologians’ unsuccessfu

Molecular Imprinted Nanocomposites for Green Chemistry

Nanocomposite materials which are considered ‘green’ refer to non-toxic, biodegradable and renewable nanocomposites. The reasons of preferring green nanocomposites much more could be explained by environmental friendly, fully degradability, renewability and sustainability in all respects. Furthermore, the production of green nanocomposites should not be based on toxic chemicals. When their functio

Framgångsfaktorer som motiverar statliga tjänstemän inom arbetsförmedlingen

Vi ägnar en stor del av våra liv på arbetet och det är genom vår roll vi tvingas uppfylla de krav som förväntas på oss. Vad vi gör i våra liv avgörs till stor del av vad vi gör på jobbet men om arbetet inte är utvecklande och inte ger någon sorts tillfredsställelse riskerar vi att tappa motivationen. Syftet med denna studie är att öka förståelsen på vilka faktorer som motiverar arbetsförmedlare oc

Amplification of Molecular Recognition Signal on Imprinted Polymers Using Hybridization Chain Reaction

Hybridization chain reaction (HCR)-based amplification strategies have shown excellent prospects of application in detection thanks to its non-enzymatic and isothermal features. For protein biomarker detection, most bioanalytical assays are dependent on antibodies or aptamers to provide specific recognition to allow single strand DNA (ssDNA) to initiate specific HCR to realize effective signal amp

The characteristics of Michelin-starred restaurants in Mainland China, Hong Kong, Macau, and Taiwan

Chinese culinary culture has a long history of development and has unique characteristics, attracting people from all over the world. As a world-renowned restaurant award, the Michelin Guide in China plays an influential role in introducing Chinese culinary culture to the world and destination branding, while few studies have investigated Michelin-starred restaurants (MSRs) in China. This study th
