Lignocellulose is widely recognized as a Sustainable substrate for biofuels production, and the enzymatic hydrolysis is regarded as a critical step for the development of ail effective process for the conversion of cellulose into ethanol. One key factor affecting the overall conversion rate is the adsorption capacity of the cellulase enzymes to the surface of the insoluble substrate. Pretreatment
Weak alignment of requirements engineering (RE) with verification and validation (VV) may lead to problems in delivering the required products in time with the right quality. For example, weak communication of requirements changes to testers may result in lack of verification of new requirements and incorrect verification of old invalid requirements, leading to software quality problems, wasted ef
In the search for high efficiency combustion systems pulsating combustion has been identified as one of the technologies that potentially can meet the objectives of clean combustion and good fuel economy.Pulsating combustion offers low emissions of pollutants, high heat transfer and efficient combustion. Although it is an old technology, the interest in pulsating combustion has been renewed in rec
The prevalence of anastomotic strictures in esophageal anastomoses provides us with limited information about the anastomotic healing process. This prospective study evaluates the exact esophageal anastomotic diameters in 256 patients who underwent esophagectomy and esophagogastrostomy without pyloroplasty (n = 107) or total gastrectomy and Roux reconstruction (n = 149). No perioperative chemoradi
The cavitation phenomenon has today become a keystone for different areas of science and technology including various industrial processes and medicine. Recently increasing interest and much attention have been paid to study this phenomenon. The last two decades have witnessed the development of numerous devices for different important applications of considerable practical interest, and the rang
The field of wireless communication is growing rapidly, with new requirements for the next generation of mobile and wireless communications technology. In order to achieve the capacities needed for future wireless systems, the design and implementation of advanced communications techniques such as multiantenna systems is required. These systems are realized by computationally complex algorithms, r
This thesis is comprised of five papers that are all related to the subject of financial time series. We study statistical aspects of conditional heteroskedastic models commonly used in modelling financial volatility. Paper I discusses the performance of commonly known information criteria in the presence of various GARCH processes. The investigation has been performed using Monte Carlo simulatio
Purpose – The purpose of this thesis is to provide an overview of all relevant peer-reviewed articles on folksonomies, social tagging and social bookmarking as knowledge organisation systems within the field of Library and Information Science by reviewing the current state of research on these systems of managing knowledge. Method – I use the systematic literature review method in order to systema
Zirkon från magmatiska bergarter extraherades från fem granitoider i Birimianterrängen i Ghana., och detritala zirkoner provtogs från sex platser i centrala Västgrönland. Av dessa härrör en population från palaeoproterozoikum i Prøvens magmatiska komplex. De återstående fem detritala populationerna härrör från Arke-iska källor i Västgrönland. Zirkon-populationerna analyserades med LA-ICP-MS-teknikZircon were extracted from five granitoids in the Birimian terrane in Ghana, and detrital zircon were sampled from six locations in Central West Greenland. Of these, one population is derived from the Palaeoprotero-zoic Prøven Igneous Complex. The remaining five populations are derived from the Archean basement in Central West Greenland. Zircon populations were analyzed with the LA-ICP-MS techniqu
Steriliseringslagstiftningens framväxt tog sin utgångspunkt i ”degenerationen” och oron för att industrialiseringen hade skapat en biologisk försämring av befolkningen. Det var vid denna tidpunkt som tankarna om rashygienen väcktes. Genom biologisk förädling skulle befolkningskvalitén höjas. Det fanns en förhoppning att genom positiv och negativ eugenik öka fortplantningen hos den ”goda” befolkninThe emergence of the sterilization law were based on "degeneration" and fear that the industrialization had created a biological degradation of the population. It was at this point that the ideas of the eugenics evoked. By biological processing the quality of the population should increase. There was a hope that through positive and negative eugenics increase the breeding of the "go
The transformational mode of sustainability science is concerned with generating actionable knowledge and practical solutions to complex sustainability challenges in order to facilitate a transition towards sustainability by strategizing transformational pathways. However, some scholars in the field believe that sustainability science lacks such capacity, since so far greater focus has been put on
Var femte fall av dödligt våld i Sverige år 2018 bestod av dödligt våld mot kvinnor där offret och förövaren var eller hade varit i en parrelation. Mäns dödliga våld mot kvinnor i nära relationer är ett omfattande samhällsproblem som akut måste stoppas. Lagstiftning och fördömande genom rättskipning är betydelsefulla medel i striden om förändring i jämställdhetsfrämjande riktning. Det finns emelleEvery fifth case of lethal violence in Sweden 2018 was constituted by men’s lethal violence against female partners or formal partners. This kind of violence is a problem of big proportions that needs to be detained now. Legislation and condemnation through the Swedish justice system are important means to achieve change in a gender equal direction. There are however parts of the Swedish criminal
Popular Abstract in English During recent decades, significant changes in fertility pattern are seen in the Western World. Declining birth rates and smaller family sizes affect the population size, but also cause unwanted effects for the desired number of children to be achieved by the individual couple. Also involuntary childlessness is a consequence of postponing childbearing to an age where theDeclining birthrates and infertility are now a common problem in the Western World. Due to the tendency to postpone childbearing an increasing age of women who consider motherhood is generally seen. A factor closely related to female fertility is the ovarian reserve, a term used to designate both quantitative as well as qualitative aspects of the remaining gametes in the female gonads. Despite a n
This study evaluated the sample sizes necessary to estimate several soil and vegetation characteristics within 10% confidence intervals with 95% probability in three terra firme tropical rainforest sites. Across all three plots, the most spatially heterogeneous variables were measurements of total standing crop root mass, ground surface litter mass, litter fall, root growth and soil respiration wh
Abstract in UndeterminedUzbekistan, after gaining independence from the Soviet Union in 1991, had publicly declared that it would adhere to democratic governance principles in designing and implementing its public administration policies. As a newly-independent state with democracy claims, Uzbekistan had tried to establish new democratic institutions with an effort to capture international communi
On January 1, 2011 the new structural design rules (Eurocode) became valid in Sweden; these rules are common to the entire European Union. The reason for the introduction of the Eurocode is to try and eliminate trade barriers between member states. This thesis aims to show what impact this change from Boverkets structural design rules (BKR) to the Eurocode will have on the dimensioning of shear re
Prodatec is a Mexican company manufacturing office furniture and closets. As the competiveness increases there are higher demands on better quality. The company wishes to compete by heading towards a Lean Manufacturing system. The first step is to implement 5S as a natural corner stone in the production. There is also a wish to be ISO 9000 certified in the future. During autumn 2008 the autst hor
Theoretical studies assessing innovation capabilities often tend to be general. This literature might not be completely applicable in practice when it discussing utilities, which are heavily affected by their external environment. Exploring which factors that drive innovation in a utility would therefore cover a gap currently existing in innovation management literature. A theoretical contribution
