Popular Abstract in Swedish Hur kan nattaktiva insekter se i mörker med fel sorts ögon? Majoriteten av alla dagaktiva insekter har en sorts facettöga som kallas appositionsöga. Appositionsögon är anpassade till ett liv med god tillgång på ljus ? nattaktiva djur har därför i princip alltid andra sorters ögon (superpositionsögon). Anledningen till att appositionsögon fungerar bäst på dagen är att dDue to our own preference for bright light, we tend to forget that many insects are active in very dim light. The reasons for nocturnal activity are most easily seen in tropical areas of the world, where animals face severe competition for food and nocturnal insects are able to forage in a climate of reduced competition and predation. Generally nocturnal insects possess superposition compound eye

Popular Abstract in English What is common between the science of physics and global politics? They both define power in terms of energy. Indeed, the uneven distribution of petroleum reserves has been one of the main reasons of social, political and economic problems worldwide. Even more worrying is the rapid increase in the levels of greenhouse gases in the atmosphere. This is mainly caused by ouCaldicellulosiruptor saccharolyticus is an extremely thermophilic, strictly anaerobic, Gram-positive and cellulolytic microorganism with a natural ability to produce hydrogen (H2) at nearly theoretical maximum yield, i.e. 4 mol/ mol of glucose. Due to its CO2-free combustion and high energy density, among other desirable properties, H2is touted as a fuel of the future. Biological H2 production b

Aim: To examine the prevalence and characteristics of uncontrolled hypertension (HT).

Popular Abstract in Swedish Nanotekniken håller i skrivande stund på att revolutionera samhället med nya innovationer inom exempelvis elektronik och medicin. En viktig del i detta är utvecklingen av nya och förbättrade sätt att avbilda strukturer av nanometerstorlek (en nanometer är en miljarddels meter). Avancerade karakteriseringsmetoder skapar en ökad förståelse för hur nanostrukturer beter sigUltrafast nano-optics is a new and quickly evolving research field centred around the control, manipulation, and application of light on a nanometre and femtosecond scale. This can lead to improved electro-optical devices, more sensitive spectroscopy, and real-time control of chemical reactions. However, understanding the simultaneous nanometre and femtosecond evolution of nano-optical fields requ

PURPOSE: To compare the clinical outcome after carpal tunnel release in diabetic and nondiabetic patients. METHODS: We evaluated a prospective, consecutive series of 35 diabetic patients (median age, 54 years; 15 with type 1 and 20 with type 2 diabetes) with carpal tunnel syndrome, who were age- and gender-matched with 31 nondiabetic patients (median age, 51 years) having idiopathic carpal tunnel

Popular Abstract in Swedish Radiojodbehandling av sköldkörteln är den vanligaste radiofarmakaterapin. För att beräkna aktiviteten 131I som krävs för att ge en viss stråldos till sköldkörteln behöver sköldkörtelns massa och den individuella biokinetiken bestämmas. Biokinetiken består vanligtvis av det individuella upptaget av jodid och den biologiska halveringstiden av jod i sköldkörteln. Den bioloRadioiodine therapy of hyperthyroidism is the most frequently performed radiopharmaceutical therapy. To calculate the activity of 131-I to be administered for giving a certain absorbed dose to the thyroid, the mass of the thyroid and the individual biokinetic data, normally in the form of uptake and biologic half-time, have to be determined. The biologic half-time is estimated from several uptake

The road 111 that runs past Helsingborg is an important connecting road to a larger road network for the towns and areas outside of Helsingborg. The purpose of this essay is to do a research to see whether a measure is needed from an accessibility perspective and to give a proposal for an appropriated measure. The analysis is limited to the distance between the traffic point Brohult and the exit p

Kiselalger, vattenlevande, mikroskopiska organismer med kiselskal, används som bioindikatorer för vattenkvalitet eftersom de är artrika och påverkas av sin omgivning. Processen kallas Kiselalgsmetoden och utförs genom en standard, en standard jag valde att analysera. Proven tas från stenar i vattendrag och sedan görs ett preparat som är fixerat på objektglas som kan undersökas i mikroskop genom aDiatoms, water living, microscopic organisms with silicon shells, are used as bioindicators of water quality because they are diverse and influenced by their surroundings. The process is called The Diatom Method and is accomplished through a standard, a standard I have chosen to analyze. The samples are taken from stones in water streams and then a preparation is made to fix the algae on slides t

The subject of this thesis is theoretical examination of freezing phenomena inside fire sprinkler systems during activation at low temperatures in the surroundings. Many sprinkler systems are installed in environments such that they must be operable at subfreezing temperature conditions. During activation of such a system, water is assumed to penetrate a significant distance and without interrupti
