Models of Mechanics and Growth in Developmental Biology: A Computational Morphodinamics approach

Recent evidence has revealed the role of mechanical cues in the development of shapes in organisms. This thesis is an effort to test some of the fundamental hypotheses about the relation between mechanics and patterning in plants. To do this, we develop mechanical models designed to include specific features of plant cell walls. These are heterogeneous stiffness and material anisotropy as well as

Focus on the impact of climate change on wetland ecosystems and carbon dynamics

The renewed growth in atmospheric methane (CH4) since 2007 after a decade of stabilization has drawn much attention to its causes and future trends. Wetlands are the single largest source of atmospheric CH4. Understanding wetland ecosystems and carbon dynamics is critical to the estimation of global CH4 and carbon budgets. After approximately 7 years of CH4 related research following the renewed g

Supply chain processes: Linking supply logistics integration, supply performance, lean processes and competitive performance

Purpose – The purpose of this paper is to examine the value chain processes that represent the “black box” between supply logistics integration and competitive operational performance in firms. To realize this objective, the authors develop a research model which comprises a series of linkages from supply logistics integration to operational outcomes using Porter’s concept of value chain and the r

Online Estimation of Multiple Harmonic Signals

In this paper, we propose a time-recursive multipitch estimation algorithm using a sparse reconstruction framework, assuming that only a few pitches from a large set of candidates are active at each time instant. The proposed algorithm does not require any training data, and instead utilizes a sparse recursive least-squares formulation augmented by an adaptive penalty term specifically designed to

Visioning Labs with displaced academics as a design strategy for sustainable post-conflict reconstruction

Post Conflict Futures is an ongoing project, where displaced Syrian academics meet in Visioning Labs and a global scenario group to jointly reflect on possible future developments and to look for actionable leverage points to work proactively for sustainable transitions. The collective visioning aims to identify aspects that may be critical in strategies for sustainable post conflict reconstructio

Teaching in the ‘edgelands' of the school day : The organisation of Mother Tongue Studies in a highly diverse Swedish primary school

To promote attainment and inclusion, Sweden offers tuition in migrant pupils’ mother tongues as a regular school subject. However, the formulation of learning aims is problematic, and resources allocated to the subject do not correspond to ambitions expressed in steering documents. This case study presents an analysis of the organization of Mother Tongue Studies at a highly diverse urban primary s

Forming chondrules in impact splashes-II Volatile retention

Solving the mystery of the origin of chondrules is one of the most elusive goals in the field of meteoritics. Recently, the idea of planet(esimal) collisions releasing splashes of lava droplets, long considered out of favor, has been reconsidered as a possible origin of chondrules by several papers. One of the main problems with this idea is the lack of quantitative and simple models that can be u

Long-term trends in numbers of Whooper Swans Cygnus cygnus breeding and wintering in Sweden

The Whooper Swan Cygnus cygnus was a rare breeding species in Sweden during the early years of the 20th century, when total numbers likely consisted of only 20 pairs. Recent decades have however seen a marked increase in numbers and a spread in the swans’ distribution, with the number of pairs breeding in the two northernmost provinces rising from 310 to 2,700 pairs between two main surveys, in 19

Postprandial Glucagon Reductions Correlate to Reductions in Postprandial Glucose and Glycated Hemoglobin with Lixisenatide Treatment in Type 2 Diabetes Mellitus : A Post Hoc Analysis

Introduction: The extent to which postprandial glucagon reductions contribute to lowering of postprandial glucose in patients with type 2 diabetes mellitus (T2DM) is currently unknown. The aim of this analysis was to determine whether a reduction in postprandial glucagon following treatment with the glucagon-like peptide-1 receptor agonist lixisenatide correlates with a reduction in postprandial g

Burden of Diarrhea in the Eastern Mediterranean Region, 1990-2013 : Findings from the Global Burden of Disease Study 2013

Diarrheal diseases (DD) are leading causes of disease burden, death, and disability, especially in children in low-income settings. DD can also impact a child's potential livelihood through stunted physical growth, cognitive impairment, and other sequelae. As part of the Global Burden of Disease Study, we estimated DD burden, and the burden attributable to specific risk factors and particular etio

Phenotypic map of porcine retinal ganglion cells

PURPOSE: Porcine retina is an excellent model for studying diverse retinal processes and diseases. The morphologies of porcine retinal ganglion cells (RGCs) have, however, not yet been described comprehensively. The aim of the present study was to créate a classification of the RGCs using the 1, 1'-dioctadecyl-3,3,3',3'-tetramethylindocarbocyanine perchlorate (DiI) tracing method.METHODS: About 17

Humlesugan i Skåne och Danmark under 500 år

Humlesugan, Betonica officinalis L., är en avden skandinaviska florans sällsyntaste växteroch samtidigt en av de arter som har denlängsta dokumenterade historien. Den rapporteradesfrån Stehag väster om Ringsjön i Skåneav Christiern Pedersen redan 1534, Skånesäldsta litteraturuppgift där en växtart knytstill en lokal.

The Marquis de Condorcets "Esquisse d'un Tableau Historique des Progres de l'Esprit Humain" was one of the first books by Klaus Henrik Seidelin translated into Danish and published in Copenhagen in 1797. The chapter examines how Seidelin worked as a writer, translator and printer in Copenhagen. What were the conditions like for freedom of the press in 1797? How did Seidelin interpret the Enlighten

Satellite tracking of Bean Geese Anser fabalis fabalis and A. f. rossicus from spring staging areas in northern Sweden to breeding and moulting areas.

In order to determine their breeding and moulting siteswe fitted eight Taiga Bean Geese Anser fabalis fabalisand two Tundra Bean Geese A. f. rossicus with satellitetransmitters in 2007–2009 at their spring roosting sitesat Umeå and Luleå, Sweden. Nine of these transmitterstransferred GPS positions for 1–4 months. All positionswere N–ENE of the catching sites. The Tundra BeanGeese migrated to Finnm

Changes of numbers and distribution of wintering waterfowl in Sweden during forty years, 1967 - 2006.

Regular midwinter counts of waterfowl (included in theInternational Midwinter Counts, IWC, organized by whatis now Wetlands International) has been undertaken inSweden since the start in 1967 and are still going on,now as a part of the National Environmental MonitoringProgramme. After the first exploratory years includingcountry-wide surveys in 1971–1973 undertaken bothfrom the ground, the air and
