Cyclomaltodextrinases are multidomain and often dimeric proteins from the alpha-amylase family (glycoside hydrolase family 13) which frequently have been very difficult to express in active form in Escherichia coli. To express the soluble form of this type of proteins in larger quantities the expression has to be optimized. We have used and combined two strategies to increase the yield of soluble

Declining biological production as a part of an ongoing land degradation process is considered a severe environmental problem in the dry northern and northwestern regions of China. The aim of this study is to develop and adapt a satellite data-driven gross primary production model called Lund University light use efficiency model (LULUE) to temperate conditions in order to map gross primary produc

A high respiratory rate associated with the use of small tidal volumes, recommended for acute lung injury (ALI), shortens time for gas diffusion in the alveoli. This may decrease CO2 elimination. We hypothesized that a postinspiratory pause could enhance CO2 elimination and reduce PaCO2 by reducing dead space in ALI. In 15 mechanically ventilated patients with ALI and hypercapnia, a 20% postinspir

Injury patterns and epidemiologic data from 211 moped accident victims and 214 motorcycle accident casualties admitted to hospital over a 5-year period (1977-1981) have been analyzed and compared. The number of those injured in motorcycle accidents tripled; the number of moped accident victims slightly decreased in the period studied. Differences in injury pattern, sex ratio, cause of accident, an

OBJECTIVE: To characterize the clinical phenotype, with emphasis on electrophysiology and blood flow measurements, of a family with dominant optic nerve atrophy and an identified mutation in the OPA1 gene. METHODS: Seven family members were examined. Ophthalmological evaluation included testing of visual acuity, ophthalmolscopy, kinetic perimetry, color vision testing, full-field electroretinograp

Extn. of lignin from kraft black liquor is one method of lowering the large energy surplus in pulp mills. The lignin can be used as a bio-fuel to replace fossil fuels in heat or power generation, and the lignin-depleted black liquor can be reused in the cooking operation. As kraft black liquor lignin has a fairly high mol. wt., ultrafiltration can be used to selectively fractionate lignin from coo

Astronomins vetenskapliga utveckling kommer idag främst från den information som kan erhållas via ljusstrålning från teleskop. Det viktigaste är teleskopet Gaia, som är ett av de mest ambitiösa rymdprojekt som människan någonsin har genomfört. Det kartlägger över en miljard stjärnor med position, avstånd och rörelse. Genom Gaias observationer skapas den första realistiska bilden av hur vår galax, The scientific development of astronomy today mainly comes from the information that can be obtained via electromagnetic radiation. Today, the Gaia optical telescope is one of the most ambitious space projects man has ever completed. Another optical telescope LSST is designed to complement Gaia. In about 15 years it will also be possible to measure gravitational waves with the telescope LISA, whic

This report depicts the design development of a modular tool used in the creasing process of packaging material. The aim of the new design is to decrease the setup time while at the same time increase the degree of customization to create new packaging designs for small series production which is difficult with the current tool. Multiple design concepts for the new tool were generated from explori

Denna masteruppsats studerar den nuvarande upphovsrätten inom EU och fastställer om det för närvarande finns skydd för AI-producerade verk. Det finns möjlighet att skydda verk som har blivit skapade av AI-system om det finns en länk mellan den mänskliga upphovsmannen och det slutliga verket. I detta fall betraktas AI-systemet som ett redskap för att skapa ett specifikt alster. Om länken mellan denThis master thesis discusses current copyright rules and if there is presently a copyright protection for these types of works. There is a possibility to protect works that have been generated by AI’s. However, this is only possible if a human is using the AI as a ”tool”, in order to reach a certain end-goal. There has to be a clear link between the human author and the machine, otherwise neither

The increasing demand for efficient neural network (NN) inference on edge devices has driven the need for hardware-level optimizations that balance computational accuracy with energy and area efficiency. This thesis explores the design and implementation of a dynamic approximate multiplier capable of mixed-precision inference, focusing on floating-point (FP) formats. Using a logarithmic-approximat

Hybrid ventilation systems have become increasingly attractive, because they are considered to provide good indoor air quality (IAQ) with low energy consumption. In this study, we evaluate the performance of a hybrid ventilation system (operating on both mechanical and natural ventilation mode) by monitoring the IAQ (e.g. temperature, humidity, CO2 levels) and the energy consumption of a multifami

Type 2 diabetes (T2D) is a complex polygenic disease influenced by both environmental and genetic factors resulting in impaired insulin release from pancreatic beta cells and insulin resistance in target tissues. The incidence of T2D is escalating and it is projected that over 640 million people will be affected by 2040. Therefore, it is imperative to understand molecular processes that cause T2D

Excessive aggression is a common behaviour problem in dogs that can have various destructive effects on the affected people and the implicated dog. Aggressive behaviour directed towards the owner or other family members is one of the most frequently occurring aggressive phenotypes. Here, we examine the reliability of a short questionnaire assessing aggressive behaviours by two, contextually differ

Parasite specialization on one or a few host species leads to a reduction in the total number of available host individuals, which may decrease transmission. However, specialists are thought to be able to compensate by increased prevalence in the host population and increased success in each individual host. Here, we use variation in host breadth among a community of avian Haemosporida to investig

OBJECTIVE: The objective was to test the hypothesis that stress urinary incontinence in women is correlated to changes in the paraurethral connective tissue ultrastructure and metabolism.METHODS: Transvaginal biopsies were obtained from the paraurethral connective tissue in women of fertile age with stress urinary incontinence and in matched continent controls. All the stress-incontinent women wer

Purpose: The purpose of this paper is to link humanitarian logistics (HL) and supply chain risk management (SCRM) to provide an understanding of risk mitigation strategies that humanitarian organisations use, or could use, to improve their logistics preparedness. Design/methodology/approach: Based on systematic reviews of RMS in SCRM and supply chain strategies (SCS) in HL literature, a framework

Increased biological understanding of cancer diseases has resulted in a paradigm shift in the medical treatment of cancer. Despite encouraging advances, most cancer types are still incurable and cancer is the second most common cause of death in developed countries.The high price of cancer drugs is a major challenge to equal access and puts heavy strains on public health care payers. After sharp i

Species diversity promotes the delivery of multiple ecosystem functions (multifunctionality). However, the relative functional importance of rare and common species in driving the biodiversity-multifunctionality relationship remains unknown. We studied the relationship between the diversity of rare and common species (according to their local abundances and across nine different trophic groups), a
