The outdoor environment is deteriorating in many tropical cities due to rapid urbanization. This leads to a number of problems related to health and well-being of humans and also negatively affects social and commercial outdoor activities. The creation of thermally comfortable microclimates in urban environments is therefore very important. This paper discusses the influence of street-canyon geome

CYLD is a deubiquitination enzyme that regulates different cellular processes, such as cell proliferation and cell survival. Mutation and loss of heterozygosity of the CYLD gene causes development of cylindromatosis, a benign tumour originating from the skin. Our study shows that CYLD expression is dramatically downregulated in basal cell carcinoma (BCC), the most common cancer in humans. Reduced

In order to elucidate the composition of the female sex pheromone of the northern (beech) winter moth, Operophtera fagata Scharf. (Lepidoptera: Geometridae), ovipositor extracts of unmated, calling females were analysed by gas chromatography with simultaneous electroantennographic and flame ionization detection (GC-EAD/FID). Male antennal responses indicated three active components, two of which h

A mathematical model for through drying of paper at constant pressure drop was developed. The model is based on physical properties; hence, basis weight, pressure drop, drying air temperature, pore size distribution, initial gas fraction, and tortuosity are important input parameters to the model. The model was solved for different combinations of the variables basis weight, drying air temperature

In this work, three different methods were used to determine the phase behavior of alkyl ketene dimer (AKD) in supercritical carbon dioxide (SC-CO2). Rough values for the total solubility of AKD in SC-CO2 were obtained. The solubility ranges from 1 to 14 mg AKD/g CO2 at temperatures from 40 to 80 degrees C and pressures from 10 to 30 MPa. A significant increase in solubility was observed in the re

[1] Vigorous debate still surrounds the cloud electrification process and unexplained regional variations in lightning activity. Here, we show that climatological maxima in lightning activity are associated with small effective diameter D-e of ice crystals near cumulonimbus cloud tops. This relationship, unlike lightning's more well-known relationship with cloud top height, is consistent over land

In market-driven software development it is crucial to produce the best product as quickly as possible in order to reach customer satisfaction. Requirements arrive at a high rate and the main focus tends to be on the functional requirements. The functional requirements are important, but their usefulness relies on their usability, which may be a rewarding competitive means on its own. Existing met

Popular Abstract in Swedish I ett väderälskande land som Sverige finns det väl ingen som inte är bekant med den väderkarta som ger oss information om hur prognosen för den närmaste tiden ser ut? Många av oss tittar dagligen på väderrapporten och låter den hjälpa oss att bestämma om vi ska cykla eller ta bussen, sätta på grillen eller laga mat i ugnen. Genom enkla visualiseringar i form av sol, regWith the aid of modern computer technology the application of visualization and simulation technology has become increasingly important in today’s society. Through computer modelling it is possible to experience, understand and explore environments, systems or objects in two or three dimensions and to see, hear and sometimes tangibly feel them. It may be environments or objects that do not yet exi

Introduction. Along with the great expansion of research being published in Open Access (OA) journals over the last decade, the interest for analysing the OA literature using informetric methods has also increased. Most studies have focused on the citation impact of OA journals and whether OA publishing increases the chances of a research publication being cited. Fewer analyses, however, have inve

Accessibility in public outdoor environments is an important issue for persons with reduced functional capacity, for example older persons, and is also crucial for older pedestrians’ safety. The aim of the paper is to evaluate the importance and satisfaction of accessibility issues in public outdoor environments the year around as perceived by older persons (65 years old and above). Within two bef

Konceptet att sågtandande polyper kan leda till kolorektal cancer är relativt nytt. Sågtandade polyper orsakar upp till en tredjedel av all sporadisk kolorektal cancer. Trots detta är kunskaperna om sågtandade polypers etiologi, incidens, prevalens och naturalförlopp ofullständiga. Sågtandade polyper är svåra att identifiera och ta bort endoskopiskt. Endoskopister och patologer måste ha kunska

Choline acetyltransferase (ChAT) is the key-enzyme for acetylcholine (ACh) synthesis and constitutes a reliable marker for the integrity of cholinergic neurons. Cortical ChAT activity is decreased in the brain of patients suffering from Alzheimer's and Parkinson's diseases. The standard method used to measure the activity of ChAT enzyme relies on a very sensitive radiometric assay but can only be

The main goal with this thesis was to investigate the possibility to reduce the number of blades in a high pressure gas turbine row. The reason for this study was the interest to reduce the amount of cooling air needed within the blade row by reducing the wetted area, hopefully without losing efficiency. Another reason for reducing the number of blades was to reduce the costs. A new design of an

Barn och föräldrars värderingar, underlag för lösningen på ett växande trafik- och samhällsproblem? Resultat från LTH:s nya examensarbete om barns säkra och trygga skolvägar förväntas kunna ge underlag för att minska problemen skapade genom föräldrar som skjutsar sina barn till skolan. Trafiksituationen vid många svenska skolor har beskrivits som kaosartad och skapat många frågetecken för framtidThis master thesis focuses on safe and secure routes to school and the point of departure is the phenomena that parents take their children to school by car instead of using sustainable alternatives as cycling and walking. This behavior creates a number of problems around schools as congestion and lack of traffic safety. Also the roads that are used for traveling to and from school, experience the

Salinisation is a global issue which leads to desertification and soil degradation and exposure to salt is also known to inhibit microbial activity and plant growth. This study was conducted to determine the influence of salinity on microbial activity of a non- saline soil. By using Salt Induced Community Tolerance (SICT) concept I found that microbial community tolerance to salt can be induced in

Purpose: The purpose of this study is to examine the role of the perceived servicescape (i.e. color, music, cleanliness, ambient temperature, layout/function and signs/symbols) in influencing customers' behavioral intentions in Chinese fast food restaurants. Methods: In this study, a deductive approach, a quantitative methodology, and a survey research design are adopted. The data is collected

Abstract Author: Lisa Avenius Title: Suspicion that a child is being maltreated - a study of preschool teachers views on mandatory reporting The aim of this study was to get preschool-teachers views and experiences on previously researched areas surrounding the notification tendency regarding mandatory reporting. The mandatory report contains an obligation to immediately report suspected child mal

Enteric neuropathy describes a disease of the bowel caused by anomalies in the enteric nervous system. Patients suffering from this disease have symptoms including nausea, vomiting, diarrhea and pain. As enteric neuropathy is not well understood yet, its diagnosis is a non-trivial task. Research on the enteric nervous system is needed in order to gain a better understanding of this disease, makin

With an increased amount and availability of unmanned aerial vehicles (UAVs) and other remote sensing devices (e.g. satellites) we have recently seen an explosion in computer vision methodologies tailored towards processing and understanding aerial view data. One application for such technologies is in the area of search-and-rescue (SAR), where the task is to localize and assist one or several peo

I en tid med återuppbyggnad av svenskt totalförsvar efterlyser olika aktörer ytterligare kunskap om civilsamhällets frivillighet. Den tidigare forskningen om frivillighet inom det här området saknar ett djupare individperspektiv kring hur frivillighet upplevs av den civila frivilliga, i förhållande till plikt, ansvar och krav. Syftet med denna fallstudie är därför att med kulturanalys fördjupa kunIn a time of reconstruction of the Swedish total defence various actors seek more knowledge about volunteering within the civil society. Previous research on volunteering in this area lack deeper micro perspectives on civil experiences of volunteering in relation to duty, responsibility and demands. Therefore, the purpose of this case study has been to deepen the cultural analytical knowledge of t
