Trichoderma reesei produces five known endoglucanases. The most studied are Cel7B (EG I) and Cel5A (EG II) which are the most abundant of the endoglucanases. We have performed a characterisation of the enzymatic properties of the less well-studied endoglucanases Cel12A (EG III), Cel45A (EG V) and the catalytic core of Cel45A. For comparison, Cel5A and Cel7B were included in the study. Adsorption s
To develop PDT beyond treatment of thin superficial tumours, to also be an efficient treatment alternative for deeply located and/or thick tumours, a system based on interstitial illumination using multiple fibres has been developed. Conditions that could benefit from such a treatment modality are for instance malignant brain tumours and tumours in the oral cavity. In interstitial PDT one needs to
INTRODUCTION: Sympathomimetic (alpha-adrenergic) drugs are mainly used because of their vasoconstrictor properties, for nasal congestion, or as mydriatics. Although sympathomimetic drugs are used often, allergic reactions are rare, especially when the drugs are administered systemically. Cross-reactivity may exist among catecholamine derivatives, although reported data on this are contradictory. I
The cellular tumor suppressor p16 is strongly overexpressed in cervical cancers and precancers. We have previously demonstrated that infiltrating T lymphocytes reactive against p16 can be found in cervical cancer patients. Here, we analyzed whether 16 induces humoral immune responses. Sera of patients with cervical cancer, oropharyngeal cancer, colorectal cancer and autoimmune disease were include
The reproduction of female Siberian lemmings in the increase and peak phases of the lemming cycle was investigated in connection with a ship-borne expedition along the Siberian arctic tundra. The cycle phase of each studied lemming population was determined using demographic analyses, i.e. current density indices (captured lemmings per 100 traps per 24 h), information on previous density (frequenc
The influence of amylopectin (Ap) (in the form of high amylopectin potato starch, HAPP) on the rheological properties of its mixtures with amylose (Am) has been studied in small-deformation oscillatory rheometry during relatively long times (6 h). The absence of HAPP granule remnants in the samples has been considered important; therefore HAPP, Am, and HAPP-Am mixtures have been prepared at 140deg
Epidermal growth factor (EGF) is a mitogenic stimulus in many tissues and occurs in large amounts in the pancreas and salivary glands. Whether EGF is mitogenic in the pancreas is controversial, and the EGF effect has not been studied in the salivary glands. Therefore, the aim of the present study was to investigate the possible effects on the pancreas and parotid and submandibular glands at differ
Voles of the genus Microtus represent one of the most speciose mammalian genera in the Holarctic. We established a molecular phylogeny for Microtus to resolve contentious issues of systematic relationships and evolutionary history in this genus. A total of 81 specimens representing ten Microtus species endemic to Europe as well as eight Eurasian, six Asian and one Holarctic species were sequenced
The full Holocene development of the large (8100 km(2)) Vatnajokull ice cap in Iceland with its many outlet glaciers is poorly known. The idea of an early deglaciation, leading to a glacier-free period in mid-Holocene, followed by the Neoglaciation is still the main concept for the glacial history in the North Atlantic region, including Iceland. We have examined a continuous sediment record from t
Invasive exotic plant species often have fewer natural enemies and suffer less damage from herbivores in their new range than genetically or functionally related species that are native to that area. Although we might expect that having fewer enemies would promote the invasiveness of the introduced exotic plant species due to reduced enemy exposure, few studies have actually analyzed the ecologica
Global warming has largely advanced spring vegetation phenology, which has subsequently affected terrestrial carbon and water cycles. However, further shifts in vegetation phenology under future climate change remain unclear. We estimated the start of the growing season (SOS) by applying multiple extraction methods based on the NDVI3g data set, and then parameterized and evaluated 11 spring vegeta
Many of our cities have problems with air pollution and it have been shown to cause a lot of damage to human health. There are different kinds of air pollution, some are gaseous air pollutions like NOx or ground-level ozone and other air pollutions are particles. NOx forms in high temperatures from combustion processes like in a car motor. Ground-level ozone form in combination with NOx, hydrocarb
Denna studie intresserar sig för när en organisations förtroende sätts på spel. Kriskommunikation är i fokus och mer specifikt hur modejätten NA-KD har hanterat ett försök till bojkott, vilket kan kopplas till det aktuella fenomenet cancel culture. Studiens primära syfte handlar om att öka förståelsen för hur organisationer som utsätts för en liknande kris online kan hantera dessa med hjälp av resThis study is interested in when an organization's trust is exposed. Crisis communication is in focus and more specifically how the fashion giant NA-KD has handled an attempt to boycott, which can be linked to the current phenomenon of cancel culture. The primary purpose of the study is to increase the understanding of how organizations that are exposed to a similar crisis online can handle th
The famous problem of Canadian Literature in the contemporary critical landscape is how it, as an institution, denies all but certain kinds of identities. Alexander Beecroft suggests that a national literature, through its attempts to locate and articulate a communal identity and a notion of fellow-feeling, curates characteristics among members of previously numerous groups which can function to d
Centralt för uppsatsen är Leo-lagen som tillkom efter en företagsskandal på 1980-talet där ledande befattningshavare i AB Leo fått teckna aktier i bolaget till fördelaktiga villkor. Leo-lagen som nu återfinns i 16 kap. ABL stadgar att ett beslut om nyemission måste fattas av bolagsstämman med minst nio tiondelars majoritet om de som ska ha rätt att teckna aktier ingår i den av Leo-lagen utpekade fIn the centre of this paper is the 16 chapter of the Swedish Companies Act (Sw. aktiebolagslag (2005:551) (ABL)). The law was adopted after a big company scandal in Sweden during the 1980s where officials in the company where given shares at profitable terms. To prevent this scandal from occurring again the law states that a decision to issue new shares to officials has to be made at the annual sh
Diabetes is a chronic disease that affects lots of people all around the world. It greatly impacts the health of those with it and places many demands on healthcare services. Early detection of diabetes can significantly improve treatment outcomes, lower the chances of future health issues, and help patients to have a better healthier life. In this study, I evaluated the reproducibility of the per
The purpose of this thesis is to examine the views of internet stakeholders in Sweden, from the perspective of net neutrality. There does not exist one single definition of the principle, which makes defining net neutrality in the context of this thesis important. The basic concept of net neutrality is that all similar internet content should be treated equally. However there are several technical
Hearing is our second most important sense. The main focus of a surveillance camera is obviously the video but the audio shouldn't be neglected. It is possible to hear what the camera can't see and what is said in a conversation can't be showed in a video. Therefore there are good reasons to always try and achieve the best audio possible. This is not an easy task since cameras are oper
