The massive infrastructure investments of the last 10 years in Vientiane (capital of Lao PDR) saw the city’s drainage network and wetlands being replaced by hydraulically more efficient cement-lined channels designed to ensure flood protection. As a result, water quality entering the receiving That Luang wetland has significantly degraded. It was initially intended that sewage water from the city
Den 1 januari 2016 skärptes kraven för luftutsläpp från förbränningsanläggningar genom För-ordningen (2013:252) om stora förbränningsanläggningar. I förordningen skärptes bland annat kraven för utsläpp av kväveoxider, NOX. Till följd av de skärpta kraven berördes Kraftringens produktionsanläggning Gunnesboverket. På anläggningen finns tre biooljeeldade hetvatten-pannor för fjärrvärmeproduktion därNew regulations regarding emissions of air pollutants came into force as of January 1st 2016 in Sweden. The regulations are found in “The Regulation on Large Combustion Plants” SFS 2013:252. The regulation contained stricter regulations of NOX emissions which affected the energy company Kraftringen and their three biooil-fueled boilers, at the heating plant Gunnesboverket, that are used for produc
Eventuella beteendemässiga konsekvenser av pornografianvändande har undersökts flitigt under de senaste decennierna. Forskningen har dock inte inkorporerat kontextuella aspekter av pornografianvändande eller intresserat sig för möjliga samband med användarnas egen sexualitet. Denna studies första syfte var att undersöka pornografianvändande i en icke-klinisk population av 16- till 30-åringar i Sve
According to Lundquist, professor in political science at Lund University, there are six different kinds of steering that rule the activities of the authority. The different kinds of steering can be divided into two different groups&semic direct and indirect steering. Steering by order means that the superior rules how the public authority perform their duty in individual matters. Steering by
Background and Objective: Glioblastoma multiforme is a highly malignant primary brain tumor. It has no border but at best a marginal zone, however, invisible to the surgeon. An optical touch pointer (OTP) enabling differentiation of healthy and tumor tissue by means of fiber-optic fluorescence spectroscopy has been developed. In combination with an ultrasonic navigation system, the OTP may be used
We have estimated the hydration free energy for 20 neutral drug-like molecules, as well as for three series of 6-11 inhibitors to avidin, factor Xa, and galectin-3 with four different continuum solvent approaches (the polarised continuum method the Langevin dipole method, the finite-difference solution of the Poisson equation, and the generalised Born method), and several variants of each, giving
The blade tip region encounters high thermal loads because of the hot gas leakage flows, and it must therefore be cooled to ensure a long durability and safe operation. A common way to cool a blade tip is to design serpentine passages with a 180 deg turns under the blade tip-cap inside the turbine blade. Improved internal convective cooling is therefore required to increase blade tip lifetime. Pin
År 2021 reformerades lagstiftningen gällande barns rätt att komma till tals i frågor om vårdnad, boende och umgänge. I 6 kap. föräldrabalken tillkom 2 b § som stadgar att barnet ska få information och ges möjlighet att framföra sina åsikter i frågor om vårdnad, boende och umgänge. Barnets åsikter ska tillmätas betydelse i förhållande till barnets ålder och mognad. Detta är den rättsliga utgångspunIn 2021, the legislation regarding children’s right to be heard in matters of custody, residence and visitation was reformed. In chapter 6 of the Children and Parents Code, section 2 b was added which stipulates that the child must receive information and be given the opportunity to express their opinions in matters of custody, residence and visitation. The child’s opinions must be given importanc
Quantum annealing provides a promising avenue for obtaining good approximate solutions to difficult optimization problems. Protein folding represents one such problem. For testing novel algorithms and technologies, simplified lattice models are well suited, as they represent considerable computational challenges despite their simplicity. One such model is the HP model, where the protein is represe
The purpose of this paper is to measure living standards for the population of Chocó, Colombia, using four waves of the DHSurveys between 1990 and 2005. Recent maternal history allowed the construction of a pooled dataset of 3.055 children and 779 mothers. The concept of living standards is measured as the ability to ensure child and marriage survival subject to short term economic stress, which i
Objective Second language learning continues to be a field of growing interest both in academia and everyday life. As such, a more comprehensive understanding of the best learning methods remains an important area of focus. This study aimed to investigate single-session vocabulary acquisition and neural underpinnings of language learning through Diffusion Tensor Imaging (DTI), in relation to immer
In this thesis work, a highly linear passive attenuator and mixer were designed to be used in a wide-band Transmission Observation Receiver (TOR). The TOR is a low IF receiver that accepts RF frequencies from 2GHz to 7GHz, and produces corresponding IF bandwidths of 280MHz to 990MHz respectively, using low side LO injection. The dynamic range is maximized by using passive topologies for both the a
Background: The molecular out of Africa hypothesis, OOAH, has been considered as an established fact amid population geneticists for some 25–30 years despite the early concern with it among phylogeneticists with experience beyond that of Homo. The palaeontological support for the hypothesis is also questionable, a circumstance that in the light of expanding Eurasian palaeontological knowledge has
Breast cancer is the most common cancer among women in Sweden. To be able to treat the disease it is important that it is detected at an early stage. In Sweden, women between 40 and 74 years are regularly offered screening with mammography to detect abnormalities in their breasts. The mammograms give the radiologist a good image of the breasts’ appearances, but it is difficult to detect structures
Purpose: To translate, validate, and evaluate the psychometric properties of the German version of Keratoconus Outcomes Research Questionnaire (KORQ). Methods: This prospective study included 3 phases. In phase 1, the KORQ was translated in a standardized way; in phase 2, Rasch validation was performed; in phase 3, the validated questionnaire was evaluated in a separate patient cohort. All patient
Sterols regulate several physico-chemical properties of biological membranes that are considered to be linked to function. Ergosterol is the main sterol molecule found in the cell membranes of yeasts and other fungi. Like the cholesterol found in mammalian cells, ergosterol has been proposed to have an ordering and condensing effect on saturated phospholipid membranes. The effects of cholesterol h
The aim of this masters dissertation is to investigate how problems that includes fluids can be solved numerical through FE-analysis. The problem at hand is to predict the impact force implied by breaking ocean waves on vertical coastal structures. The importance that coastal areas has on human society both from a perspective of economy, infrastructure and recreation are indubitable. Furthermore,
Abstract in UndeterminedNanoindentation has recently gained attention as a characterization technique for mechanical properties of biological tissues, such as bone, on the sub-micron level. However, optimal methods to characterize viscoelastic properties of bones are yet to be established. This study aimed to compare the time-dependent viscoelastic properties of bone tissue obtained with different
Lignin, the world's most abundant biopolymer with high aromaticity, has huge potential as a renewable feedstock replacing petroleum for the production of chemicals, fuels and functional materials. The enhanced utilization of lignin would improve the economic viability of existing pulp and paper mills, as well as lignocellulosic biorefineries, where lignin is highly available, but mostly incinerate
