The demand for organic products is high in France, and the amount of land under organic production is increasing. This is due to the Organic Certification label, that helps to bring up the price and attractiveness of organic goods, and the Common Agricultural Policy (CAP) that provides farmers funds and assistance. However, organic farmers in France still struggle to make ends meet which is detrim
This master thesis investigates how to perform irrational decimation, the process of reducing the sample rate of a signal, for high throughput systems. The thesis work consists both an algorithmic part and an implementation part. In the algorithmic part, an algorithm that could cope with the requirements is found, and investigated due to different aspects. A group of filters that are investigate
In this paper, we address distributed convergence to fair allocations of CPU resources for time-sensitive applications. We propose a novel resource management framework where a centralized objective for fair allocations is decomposed into a pair of performance-driven recursive processes for updating: (a) the allocation of computing bandwidth to the applications (resource adaptation), executed by t
Background: Traditionally average values of the whole population are considered when analysing microbial cell cultivations. However, a typical microbial population in a bioreactor is heterogeneous in most phenotypes measurable at a single-cell level. There are indications that such heterogeneity may be unfavourable on the one hand (reduces yields and productivities), but also beneficial on the oth
The introduction of the laparoscope was a milestone within gynecologic surgery. Despite evidence of better perioperative outcome compared to laparotomy, laparoscopy is mostly performed for less advanced surgical procedures and the uptake of laparoscopic hysterectomy has been slow. An effort to preserve the clinical benefits of laparoscopic surgery and facilitate the performance of more advanced su
Background and Purpose-High-dose heparin has been used extensively to treat patients with progressive ischemic stroke, but the scientific support is poor and the current stroke guidelines advise against its use. We studied how heparin treatment for progressive stroke has been discarded in Sweden. Methods-All 78 hospitals in Sweden that admit acute stroke patients participate in Riks-Stroke, the Sw
Endovascular aneurysm repair (EVAR) represents one of the greatest advances in vascular surgery over the past 50 years. In contrast to conventional aneurysm repair, EVAR requires accurate preoperative imaging and stringent postoperative surveillance. Duplex ultrasound (DUS), transesophageal echocardiography, intravascular ultrasound, computed tomography (CT) and magnetic resonance (MR), each provi
Vid fångst av nattfjärilar använder man ofta lockbeten. De består av en trasa eller liknande som dränks in med någon lockande vätska och hängs upp i t.ex. ett träd. Under natten kan betet inspekteras många gånger och djur samlas in. Recepten för den lockande vätska varierar kraftigt mellan olika samlare men innehåller alltid jästa produkter av något slag. En stor skiljelinje går mellan beten som b
Popular Abstract in Swedish Stroke är en sjukdom som främst drabbar äldre och är den största anledningen till att människor får olika slags handikapp såsom förlamning och afasi. Det finns ännu ingen effektiv behandling för att lindra symtom och lidande efter en stroke, förutom rehabilitering, och därför kostar stroke samhället enormt mycket pengar. Befolkningen blir allt äldre, vilket även medför Cell replacement by neural transplantation can, in animal models of neurodegenerative diseases, reconstruct damaged brain circuitry. In the clinical situation, the graft material used for cell therapy must, most likely, be of human origin. The human fetal brain is one potential source of neural stem cells (NSCs) for cell replacement therapy in neurodegenerative disorders such as stroke. Stroke is
Amendments to Articles 3.3 and 3.4 of the Kyoto Protocol have meant that detection of vegetation change may now form an interracial part of national soil carbon stocks. In this study multispectral multi-platform satellite data was processed to detect change to the surface vegetation of four peatland sites and one heath in Ireland. Spectral and spatial thresholds were used on difference images betw
We investigate depletion interactions between inert hard colloids in the presence of ideal polymers, with a focus on the case where the polymer radius of gyration (R-g) is equal to the radius of the colloids (R-c). We first establish structure and fluid-fluid phase equilibria of this model system as accurately as possible. To achieve this, we replace the ideal polymers by "effective spheres'', usi
An integrated system for the production of hydrogen by gasification of biomass and electrolysis of water has been designed and cost estimated. The electrolyser provides part of the hydrogen product as well as the oxygen required for the oxygen blown gasifier. The production cost was estimated to 39 SEK/kg H-2 at an annual production rate of 15 000 ton, assuming 10% interest rate and an economic li
Popular Abstract in Swedish Avhandlingen utgår från förhållandet att symtom på psykisk ohälsa har tenderat att öka över tid i exempelvis de undersökningar som görs regelbundet av hälsorisker och ohälsa i form av olika så kallade folkhälsoenkäter och liknande undersökningar av hälsoläget i den svenska befolkningen. Det finns en diskussion bland forskare kring vad denna tendens står för, exempelvis Mental disorders, especially depression, have been increasingly described as a growing burden to global public health. Critics argue, however, that the use of mental health surveys, underlying these descriptions, tends to overestimate the prevalence of mental disorders by not distinguishing everyday experiences of distress from pathological conditions. This medicalization of public health is belie
There is substantial evidence that preschooler’s performance in early math is highly correlated to math performance throughout school as well as academic skills in general. One way to help children attain early math skills is by using targeted educational software and the paper discusses potential gains of using such software to support early math development. Furthermore it is argued that the con
There is currently a strongly growing interest in obtaining optimal control solutions for vehicle manoeuvres, both in order to understand optimal vehicle behaviour and, perhaps more importantly, to devise improved safety systems, either by direct deployment of the solutions or by including mimicked driving techniques of professional drivers. However, it is non-trivial to find the right combination
Flow injection analysis provides a convenient platform for the use of biosensors in the monitoring of bio-processes. A major requirement in bioprocess monitoring is real time information about various process parameters like concentration of products and substrates, flow rates, and injection volumes. Depending on the application, the monitoring requirements vary and this results in a need for diff
Despite decades of intensive research, to date, there is no accepted diagnosis for Parkinson's disease (PD) based on biochemical analysis of blood or CSF. However, neurodegeneration in the brains of PD patients begins several years before the manifestation of the clinical symptoms, pointing to serious flaw/limitations in this approach.
