Histidine protonation states are key in the LigI catalytic reaction mechanism

Lignin is one of the world's most abundant organic polymers, and 2-pyrone-4,6-dicarboxylate lactonase (LigI) catalyzes the hydrolysis of 2-pyrone-4,6-dicarboxylate (PDC) in the degradation of lignin. The pH has profound effects on enzyme catalysis and therefore we studied this in the context of LigI. We found that changes of the pH mostly affects surface residues, while the residues at the active

The Effect of Coupling Memory and Block Length on Spatially Coupled Serially Concatenated Codes

Spatially coupled serially concatenated codes (SC-SCCs) are a class of spatially coupled turbo-like codes, which have a close-to-capacity performance and low error floor. In this paper, we perform a comprehensive design space exploration, revealing different aspects of SC-SCCs and discussing various design trade-offs. In particular, we investigate the impact of coupling memory, block length, decod

Dispersal and spatiotemporal distribution of Protapion fulvipes in white clover fields : implications for pest management

Yield loss caused by insect pests remains a substantial problem in agriculture. Chemical control, with potential negative effects on non-target organisms, is still the main tool for pest management. For pest species with limited dispersal capacity, rotation of the crop in time and space has potential as an alternative management measure. This is particularly important in organic farming, where mos

Evolution of conventional communication : A cross-cultural study of pantomimic re-enactments of transitive events

This study addresses the postulate of non-conventionality of pantomime, inherent in pantomimic scenarios of language origin. Since lack of semiotic conventions does not preclude micro-conventions resulting from cultural differences, pantomimes should be easier to interpret when the actor and recipient share the same culture than between two different cultures. In the study, Italian and Polish amat

Towards Fully Pipelined Decoding of Spatially Coupled Serially Concatenated Codes

Having close-to-capacity performance and low error floor, even for small block lengths, make spatially coupled serially concatenated codes (SC-SCCs) a very promising class of codes. However, classical window decoding of SC-SCCs either limits the minimum block length or requires a large number of iterations, which increases the complexity and constrains the degree to which an SC-SCC decoder archite

Feasting with Buddhist Women : Food Literacy in Religious Belonging

This ethnographic study shows that women’s knowledge and practices involving food in Japanese Buddhist contexts circulate as gendered currency. It emphasizes how what we term “food literacy” cultivates aesthetic and affective senses of belonging among Buddhist practitioners. We argue that this embodied knowledge helps women negotiate their experiences of Buddhism and show how these experiences art

Investigation on residual stress evolution in nickel-based alloy affected by multiple cutting operations

Machining-induced residual stresses in a part can significantly influence its performance and service time. It is common that the final surface of the part is produced after multiple cuts in the machining process. In multiple cuts, the previous cuts could often generate accumulated strain/stress and temperature on the part surface. These accumulated strain/stress and temperature will be brought to

Evolution of lignin decomposition systems in fungi

Lignin represents the second most abundant biopolymer of the plant cell wall. Among microorganisms, fungi are the most efficient lignin decomposers. The discovery of ligninolysis by fungi could have altered the ancient carbon cycle at the global scale and it is still one of the processes that determine carbon sequestration and soil formation. Understanding the evolution of ligninolytic systems rep

Variants in BANK1 are associated with lupus nephritis of European ancestry

The genetic background of lupus nephritis (LN) has not been completely elucidated. We performed a case-only study of 2886 SLE patients, including 947 (33%) with LN. Renal biopsies were available from 396 patients. The discovery cohort (Sweden, n = 1091) and replication cohort 1 (US, n = 962) were genotyped on the Immunochip and replication cohort 2 (Denmark/Norway, n = 833) on a custom array. Pati

Metabolic factors and the risk of Dupuytren’s disease : data from 30,000 individuals followed for over 20 years

Dupuytren’s disease (DD) is a fibroproliferative disorder affecting the palmar fascia of the hand. Risk factors include diabetes mellitus (DM), whereas a high body mass index (BMI) is associated with a lower prevalence of DD. The aim of this study was to further elucidate risk and protective factors for the development of DD using longitudinal population-based data from the Malmö Diet and Cancer S

On inter-industry relatedness and regional economic development

The dissertation aims to advance our understanding about the role of local industry structure in regional economic development. More specifically, it investigates how relatedness between local industries (i.e. similarities in what kind of knowledge industries use) contributes to and constrains regional economic development. Empirically, the dissertation investigates Swedish regional development in

Geochemical fingerprints of ginkgoales across the triassic-jurassic boundary of greenland

Premise of research. Geochemical fingerprinting of fossil plants is a relatively new research field complementing morphological analyses and providing information for paleoenvironmental interpretations. Ginkgoales contains a single extant species but was diverse through the Mesozoic and is an excellent target for biochemical analyses. Methodology. Cuticles derived from fresh and fallen autumn leav
