In insects airborne odors are detected by the odorant receptors (ORs) and ionotropic receptors (IRs), located on the dendritic membrane of the olfactory sensory neurons (OSNs) housed in olfactory sensilla. The OR and IR gene families show high plasticity in lineage expansion and contraction following the birth-and-death evolutionary model. Gene duplication is an important mechanism underlying the
The overall aim of this thesis is to examine how walking as a transport mode is constructed in the planning realm, affected by the built environment and perceived by the individual. This aim is related to the following research questions: (1) How are pedestrians and walking understood, constructed and perceived in the planning context? (2) How does individual traits and the built environment affec
Purpose: In this study, we examine the data from Chinese companies to test the relationship between cash flow and investment. While a wide assortment of previous research has examined the relationship between cash flow and investment, they have largely focused on empirical analysis from an US or a Western perspective. But, to date, little attention has been paid to such relationship using empirica

Organic farming may contribute substantially to future agricultural production worldwide by improving soil quality and pest control, thereby reducing environmental impacts of conventional farming. We investigated in a comprehensive way soil chemical, as well as below and aboveground biological parameters of two organic and two conventional wheat farming systems that primarily differed in fertiliza

Popular Abstract in Swedish Introduktion: Validitet handlar enkelt uttryckt om överensstämmelse med sanningen eller exempelvis om ett instrument mäter det som är avsett. Validitet kan också ses som ett mer komplext begrepp, innefattande aspekter som nytta, relevans, värderingar och sociala konsekvenser. Validitet förutsätter reliabilitet som är ett mått på tillförlitlighet, noggrannhet eller reproAbstract Introduction: Validity is important at different levels in psychiatry. Valid structured instruments are important aids in screening and diagnostics, in both research and clinical practice. An aim of the diagnostic procedure is to yield valid diagnoses. Ultimately, the validity of structured instruments (non-empirical) and clinical diagnoses depends on the validity of the diagnostic class
That data from polar orbiting satellites have detected a widespread increase in photosynthetic activity over the last 20 years in the grasslands of the Sahel is justifies investigating its role in the tropical carbon cycle. But this task is undermined because ground data that are generally used to support the use of primary production models elsewhere are lacking. In this paper, we profile a Light
Popular Abstract in Swedish Gastroesofageal refluxsjukdom innebär att maginnehåll backar (reflux) upp från magsäcken till matstrupen på ett onormalt sätt. Hos den friska individen finns flera mekanismer som skyddar matstrupen från reflux, vilket tydligt åskådliggörs av att man efter en måltid kan ställa sig upp och ner utan att föda backar upp i matstrupen. Vid refluxsjukdom föreligger defekter inEsophageal pH monitoring is important in the clinical management of patients with symptoms suggestive of gastroesophageal reflux disease (GERD), and in research aiming to clarify the mechanisms involved in the development of GERD complications. Catheter-based techniques for pH recording are uncomfortable, not well tolerated by all patients and cannot reliably measure acid exposure in the most dist
Molten salt applications are challenging from a material perspective. This degree project was carried out at Alfa Laval to give them a better understanding of the corrosion of solar salt on the standard heat exchanger material stainless steel 321. Similar tests have previously been performed externally. By developing test methods for in-house corrosion testing time and money can be saved. In thi
Sweden’s substantial building stock from the million programs is in need of renovations. These residential buildings were built without major attention to energy demand or architectural aesthetics. Until now, property owners have hesitated to carry out energy renovations due to the investment cost. The aim of this master thesis was to propose an energy-efficient renovation procedure whilst takin
On 25 May 1993, the United Nation Security Council took the extraordinary and unprecedented step to establish the International Criminal Tribunal for the Former Yugoslavia (ICTY) as means for restoration and maintenance of international peace and security. This was a major event for the all those who are concerned about serious breaches of international humanitarian law and the introduction of law
Penningtvätt har länge varit ett uppmärksammat problem, men inte förrän på senare år, särskilt efter den 11 september 2001 och terroristattackerna i USA har stora krafttag gjort att bekämpningen av problemet kommit igång. Bekämpningen och förhindrandet av penningtvätt och finansiering av terrorism är även viktigt utifrån ett större perspektiv. Om man kan strypa finanserna för kriminell verksamhet,Money laundering has for a long time been an acknowledged problem, now more than ever. Especially after 9/11 2001 and the terrorist attacks in the USA, joint efforts have made combating the problem a serious matter. Combating and prevention of money laundering and terrorism financing is also important from a larger perspective. If you can close off finances of criminal activity, you are one step c
To examine nanoparticle toxicity there is a need to produce defined nanoparticles dispersed in a colloidal suspension. Such a solution could also be interesting for other fields such as nano-medicine. In order to disperse the particles in the liquid there are often surfactant added to the process that alternates the surface of the particles. As the research shows that the surface of a nanoparticle
Over recent decades, use of insecticides to protect plants from pests and harmful insects have increased manyfold. Neonicotinoid insecticides, such as Imidacloprid (IMI) acts as partial agonists on nicotinic acetylcholine receptors which are widely present in both the central and peripheral nervous system of insects. Pollinators like Eristalis tenax are frequently exposed to these pesticides but h
Uppsatsen undersöker och granskar hur gällande rätt, inom sakrätten reglerar och präglar användandet av säkerhetsöverlåtelser som kreditsäkerhet. Därutöver undersöks även det avtalsförhållande som långivaren och låntagaren befinner sig i när äganderätten, gällande säkerhetsobjektet, övergått till långivaren. Även nyttjande- och separationsrätten diskuteras och undersöks i förhållande till hur rättThe paper examines and reviews how the current right of rem regulates and characterizes the use of security transfers as credit security. In addition, the contractual relationship that the lender and the borrower find themselves in when the ownership of the collateral has been transferred to the lender is also examined. The right of use and separation is also discussed and examined in relation to
Purpose: The purpose of this work was to explore the possibility to compare treatment-planning- and treatment-delivery systems for intensity modulated radiation therapy (IMRT) using an objective approach. The approach investigated was the Pareto front concept. An additional aim was to adequately compare three different IMRT treatment planning and delivery systemsMaterials and methods: In IMRT trea
För att utöka biogasproduktionen i Västra Götalandsregionen (VGR) kan restströmmar från jordbrukssektorn fungera som en storskalig leverantör av biomassa. Produktionen av biogas minskar beroendet av fossila bränslen och rötresten som bildas kan också återföras till jordbrukssektorn, vilket skapar ett slutet kretslopp. I detta examensarbete granskades utökningen genom en kartläggning av biogasproduTo expand the biogas production in Region Västra Götaland (RVG), residual streams from the agricultural sector can function as a large-scale supplier of biomass. The production of biogas decreases the dependence of fossil fuels and the digestate that is formed can also be returned to the agricultural sector, creating a closed loop. The expansion was assessed in this thesis by the investigation of
IntroductionBeta-lactam antibiotics are essential in the treatment of Gram-negative bloodstream infections. The effect of beta-lactam antibiotics depends on the time of unbound antibiotic concentration above the minimal inhibitory concentration (MIC). An antibiotic concentration above MIC during the whole dosing interval (100% ƒT > MIC) has been suggested as a target for severe infections. The aim
