Lignocellulose-based dicarboxylate monomers for aromatic polyesters: synthesis, characterization, and properties
Captive offshoring, innovation and market diffusion : evidence from the Swedish Community Innovation Survey
Although the effects of captive offshoring on firm innovation have increasingly become a subject of study, the literature did so far not distinguish between the effects on introducing innovation as opposed to the effects their market diffusion. This distinction is important. By integrating insights from the innovation diffusion literature, we argue that the effects of captive offshoring on home ba
Postnatal phenobarbital for the prevention of intraventricular haemorrhage in preterm infants
Background: Intraventricular haemorrhage (IVH) is a major complication of preterm birth. Large haemorrhages are associated with a high risk of disability and hydrocephalus. Instability of blood pressure and cerebral blood in the newborn flow are postulated as causative factors. Another mechanism may involve reperfusion damage from oxygen free radicals. It has been suggested that phenobarbital stab
Hand-arm vibration : Swedish carpenters' perceptions of health and safety management
Background: Workers in the construction industry are highly exposed to vibration from handheld equipment, which can have negative effects on the nerves and blood vessels in the hands. Employers in this industry often fail to comply with legislation regarding vibration exposure. Aims: To assess carpenters' perceptions of proactive health and safety (H&S) management regarding hand-arm vibration
AMENABILITY PROPERTIES OF TσA,σB
We first define a new multiplication on triangular Banach algebras. Then study amenability, weak amenability, biflatness and biprojectivity of these algebras.
Essays on the effect of health care and the environment on health
This thesis consists of three self-contained papers studying different topics in health economics. The first chapter studies the substitution effect between in-person physician visits and a new type of doctor visits, direct-to-consumer (DCT) telemedicine, where a person can call a doctor directly via an app. To causally assess to which degree DCT consultations substitute for in-person consultation
Personalgruppens psykologi
Personalgruppens psykologi ger en grundläggande översikt över de psykologiska processer som kännetecknar en personalgrupp. Enkelt och lättillgängligt presenterar författarna teorier och begrepp som kan fungera som redskap för att förstå arbetslagets och samarbetets psykologiska villkor. Teori varvas med praktiska övningar och resonemang kring hur samarbetsproblem och konflikter kan förebyggas och

ON KANNAN-GERAGHTY MAPS AS AN EXTENSION OF KANNAN MAPS
Extending the concept of weakly Kannan maps on metric spaces, we study the maps as $f:X\rightarrow X$ on a metric space $(X, d)$ satisfying condition $d(f(x), f(y)) \leq (1/2)\beta(d(x, y))[d(x ,f(x)) + d(y, f(y))]$ for every $x, y\in X$ and a function $\beta: [0, \infty)\rightarrow [0,1)$ where for every sequence $t=\{t_n\}$ of non-negative real numbers satisfying $\beta(t_n)\rightarrow 1,$ while
Self-reported quality of life before, during, and after pregnancy in women with CHD
Background:Adults with CHD are a growing patient group and childbirth is a relatively new phenomenon. EQ-5D is commonly used to measure health-related quality of life. We sought to investigate EQ-5D status before, during, and after pregnancy in women with CHD.Methods:We identified 128 pregnancies in 86 CHD women giving birth in Skåne County during 2009–2021. Repeated measures ANOVA was performed t
Spontaneous free-standing nanostructured film growth in polyelectrolyte-surfactant systems
Substitution of a polyelectrolyte for silica during formation of surfactant-templated films produces similar nano- and macroscale structures confirming that silica acts as a polyelectrolyte during thin film self-assembly.
Layer-by-layer deposition of open-pore mesoporous TiO 2- Nafion® film electrodes
The formation of variable thickness TiO 2 nanoparticle- Nafion® composite films with open pores is demonstrated via a layer-by-layer deposition process. Films of about 6 nm diameter TiO 2 nanoparticles grow in the presence of Nafion® by "clustering" of nanoparticles into bigger aggregates, and the resulting hierarchical structure thickens with about 25 nm per deposition cycle. Film growth is chara
Growth-collapse mechanism of PEI-CTAB films at the air-water interface
We reveal a growth-collapse mechanism for self-assembled films of polyethyleneimine (PEI) and cetyltrimethylammonium bromide (CTAB) at the air-water interface. The work involved the quantification of film thickness on the micron scale through tracking oscillations in the amplitude and phase angles using single-angle, single-wavelength ellipsometry. Our results allow us to propose the following int
Incorporation of sparingly soluble species in mesostructured surfactant-polymer films
Recently we have investigated the formation of novel thick, solid, mesostructured films of polymer/surfactant mixtures which form spontaneously at the air-solution interface. Here we report studies of the effect of adding a series of sparingly soluble species to the precursor solution, to alter the mesostructure of cetyltrimethylammonium bromide/polyethylenimine films and to investigate the incorp
Further Improvements in the Long-Range Order of MCM-41 Materials
Synthetic methods for making an all-silica MCM-41 mesoporous silicate of high long-range order are reported. The product shows up to seven orders of X-ray diffraction and good stability under calcination conditions. The greatest improvement in structure occurs when the pH is held between 9 and 10 during synthesis and the sulfate anion is present.
Current understanding of formation mechanisms in surfactant-templated materials
Surfactant-templated materials are created through self-assembly in solutions containing both surfactant micelles and an inorganic species. The resulting materials are composites containing an organized surfactant micelle array encapsulated in the inorganic material. Removal of the surfactants generates nanoscale pores which replicate the highly organized micelle phase, producing high surface area
Probing hysteresis during sorption of cyclohexane within mesoporous silica using NMR cryoporometry and relaxometry
The conventional data analysis methods for obtaining a pore size distribution (PSD) from gas sorption data make several critical assumptions that impact significantly on the accuracy of the PSD thereby obtained. In particular, assumptions must be made concerning the nature of the pore-filling or emptying process in adsorption, or desorption, respectively. The possibility of pore-pore interactions
Electro-deposition of thin cellulose films at boron-doped diamond substrates
Cellulose films of variable thickness are electro-deposited from aqueous alkaline thiourea solution onto polished boron-doped diamond substrates in an anodic process. Films with "net-like" topography are formed and shown to consist of both cellulose-I and cellulose-II components. Properties of these films are investigated. When immersed in aqueous electrolyte solution, ion partitioning into the el
Association of titania with nonionic block copolymers in ethanol : The early stages of templating and film formation
We have prepared self-supporting, free-standing titania-surfactant mesostructured films via spontaneous growth on the surface of ethanolic solutions, as an alternative synthetic route to evaporation induced self-assembly. The initial stages of surfactant templating and interfacial film formation in alcoholic solutions of titania with a polyethylene-poly(ethylene glycol) surfactant have been observ
