Hypothesis: En bloc esophagectomy (EBE) provides improved survival over transhiatal esophagectomy (THE) in patients with similarly sized transmural tumors (T3) and lymph node metastases (N1). Design: A retrospective case-control study of 2 methods of esophageal resection for cancer. Setting: University hospital (tertiary referral center for esophageal disease). Patients: There were 49 patients (27
In order to reduce the total enzyme consumption in high-solids static hydrolysis of nonwashed steam-exploded willow Salix caprea by mixed cellulase of Trichoderma reesei + Aspergillus foetidus, two different approaches were proposed. In the first case, the enzyme activity adsorbed on residual solids after extended hydrolysis was used for hydrolysis of the newly added substrate. The initial mixing
A new criterion is applied for characterization of the kinetic design of enzymes that should be favoured by a selective pressure in the direction of increased metabolic reaction flux. According to this criterion, the selectively favoured state of a metabolic sequence of enzyme reactions conforming to Michaelis-Menten kinetics is identical with the uniform one which is known to optimize reaction fl
It is shown that the numbers of high level crossings by p dependent stationary Gaussian processes have asymptotically independent Poisson distributions if the observation interval and the height of the level increase in a coordinated way. The processes may be highly correlated, even linearly dependent.
Abstract Parkinson’s disease (PD) is characterized by selective loss of dopaminergic neurons and progressive accumulation of intracellular alpha synuclein protein aggregates known as Lewy bodies. Due to pathological links to both sporadic and inherited cases of PD, alpha synuclein (asyn) has become a focal point for study, although the exact mechanisms of its toxicity are not known. In contrast to
This thesis is focusing on the protection of fundamental human rights at work for third country migrant workers in the European Union, a region which attracts more and more migrant workers in recent years. The first Chapter introduces the background briefly, the methodology and the sources on which the research is conducted on and provides the scope and definition of the issues which are under dis
A need for autonomous electro-mechanical machines performing tasks that can save human efforts and even be deployed in hazardous environments along with the research in the field of human mind and body has led to new fields often called AI Robotics. To provide a mean for stimulating students and researchers around the world for promotion of this new field, an annual world championship, Robocup, ha
Som en effekt av den globala strävan som syftar till att motverka klimatförändringar som tillskrivs ökande koldioxidnivåer i atmosfären försöker man hitta okonventionella sätt att minska koldioxidutsläpp. CCS anses vara en metod med stor potential för detta syfte vilket har föranlett en världsomspännande prospektering av platser som kan användas för geologiskt lagring av koldioxid. Detta arbete As a part of a global attempt to mitigate impending climate change owing to increasing atmospheric CO₂levels unconventional methods which may reduce CO₂ emissions are extensively researched. Carbon Capture and Storage,(CCS) is considered to be a promising method for this purpose. As a consequence, worldwide prospection of geological sites in which CO₂ may be stored is currently underway. This th
Bolivia holds among the biggest reserves of lithium in the world. Lithium-ion batteries are essential components in electric vehicles, solar panels, and wind turbines, and are therefore crucial for a global transition from fossil fuels to renewable energy. Meanwhile, the extraction process of lithium can cause large environmental damage. Bolivia has previously failed to industrialize its lithium,
The “territorial peace” runs as a buzzword around Colombian peacebuilding. A so-called territorial approach was adopted in the beginning of the Havana Peace Talks, as a means of creating locally based, differentiated modes of peacebuilding, and addressing the structural neglect of Colombia’s diverse rural areas. This study highlights the experiences of Colombian indigenous peoples in the context o
As society becomes more ecologically conscious there is a push toward the use of materials with a smaller environmental burden, one of these materials is glulam (GLT), which has gained a lot of traction in recent years not only for ecological reasons but for its ease in manufacture, transport, noise dampening, etc. The focus of this project was to evaluate the influence of different joint configu
This study tests the efficiency of the Swedish and the Dutch stock markets by analyzing the performance of two dividend strategies – dividend capturing and dividend timing. To test these strategies and what factors influence them, the researchers collect a sample of 95 different firms, about half from each country and a total of over 8 000 dividend observation. A cross sectional regression is run
Wine is an important cultural crop and is grown in vineyards that sometimes claim to have a unique "terroir" - a specific taste and character based on their physical attributes and location. Regulations and previously published work are not easily available, into how to measure and assess this terroir. It is important for countries such as Sweden to have a terroir assessment system, whic
Purpose – While e-commerce marketplaces have changed the way SMEs operate across borders, literature connecting digital platforms with the internationalisation of firms is scarce. Although the Uppsala Model and the Born Global concept acknowledge the influence of digital technologies, they do not capture the phenomenon of e-commerce marketplaces as a new mode of entry. In light of the new opportun
In Sweden the Sami people is a national minority of indigenous people. Traditionally they are living in northern Sweden but can be found all over the country. The Church of Sweden has a long tradition of giving church services using the native Sami language in the Swedish part of Sapmi, the Sami people name of their land. The problem of recruiting Sami speaking clergy has always been great and dif
The tawny pipit (Anthus campestris) is a migrant bird adapted to dry, sandy habitats. In southern Sweden, land use changes have resulted in a reduction of suitable areas, affecting the birds’ population size. The SandLife Project was created with the goal to restore those sandy grasslands and improve local conditions to stimulate the recovery of biodiversity. In order to compare the current and th
This thesis is a case study on the family reunification procedure for refugees in Denmark, in the context of an increasingly restrictive environment. It sought to find out how structural facets of Danish immigration law interact with and influence the practices of navigating a family reunification process, for people with a refugee background. Two phases of semi-structured interviews were conducte
Mammals express thirteen different isoforms of the membrane-bound water channel aquaporin in a tissue-dependent manner. From a medical point of view, two of the most studied isoforms are aquaporin (AQP0), also known as major intrinsic protein and aquaporin 2 (AQP2). AQP0 is exclusively expressed in the mammalian eye lens and responsible for the transport of water across lens fiber cell membranes t
The interaction of a solid target with an ultra-high intensity laser pulse can result in the laser plasma acceleration of ions. The recent proposal of a new laser plasma ion acceleration scheme, named chirped standing wave acceleration, has created interest in a new class of ultra-thin solid target materials, either freestanding or as a part of novel compound targets. In this thesis, it is assesse
