Holocene climate variability at multidecadal time scales detected by sedimentological indicators in a shelf core NW off Iceland

A Holocene sediment record is presented from the Djupall trough, situated on the inner shelf northwest of Iceland. The paleoclimatic development has been interpreted on the basis of mass accumulation rate, carbonate content, mean grain size, sediment petrology and 29 radiocarbon dates. The results demonstrate in the early Holocene (10,000-8000 cal year BP) high sediment accumulation rates attribut

How technology is reshaping the practice of nongynecologic cytology - Frontiers of cytology symposium

To pay tribute to the Founders of Acta Cytologica, this Golden Anniversary symposium on nongynecologic cytology revives the written symposium style of the 1950s. Participants from countries throughout the world were asked how new technologies are currently applied in their laboratories and whether future advances and challenges can be predicted. The specific questions and the participants' answers

Translation of sustainability ideas in tourism networks: Some roles of cross-sectoral networks in change towards sustainable development

The process of change has been considered within many areas of contemporary thinking. Consequently, many aspects of change have been explored through different theoretical angles. Using insights from 'translation' theory, this article considers critical factors that affect cross-sectoral networking process for SD-a popular form of collaboration. The empirical data for this study comes from the inv

On Radiative Heat Transfer Modeling with Relevance for Combustor and Biomass Furnaces

Thermal radiation sometimes is the dominating heat transfer mode in combustion chambers and furnaces and therefore in the design of many relevant industrial facilities prediction of it is necessary. During previous years many research efforts in the radiative heat transfer field have originated and many methods and models from simple to complex have been developed. However, the field is still open

Etnicitet och övervikt: implicita arbetsrelaterade fördomar i Sverige

Särbehandling i anställningsprocessen av specifika grupper, såsom personer med en bakgrund i Mellanöstern och överviktiga, har traditionellt ansetts bero på ett medvetet val från arbetsgivarens sida. Forskning inom social kognition tyder dock på att denna särbehandling skulle kunna ske omedvetet, påverkat av arbetsgivarens omedvetna (implicita) fördomar. I den här studien har studenter och arbetsg

Requirements Engineering with Use Cases - a Basis for Software Development

Successful development of software systems depends on the quality of the requirements engineering process. Use cases and scenarios are promising vehicles for eliciting, specifying and validating requirements. This thesis investigates the role of use case modelling in requirements engineering and its relation to system verification and validation. The thesis includes studies of concepts and represe

The mechanisms controlling heat and mass transfer on frying of beetburgers. I. The influence of the composition and comminution of meat raw material

Heat and mass transfer in minced meat patties (D = 100 mm, H = 10 mm) were studied during frying from the frozen state (-20 degreesC) to a Centre temperature of 72 degreesC in a double-sided pan fryer. The chemical composition of the meat raw material was varied to study the effect of the water, fat and connective tissue content and the water-protein ratio on the mass transfer (total loss. fat and

Control of Homogeneous Charge Compression Ignition (HCCI) Engine Dynamics

The Homogeneous Charge Compression Ignition (HCCI) combustionconcept lacks direct ignition timing control, instead the autoignition depends on the operating condition. Since auto ignition of ahomogeneous mixture is very sensitive to operating conditions, a fastcombustion timing control is necessary for reliable operation. Hence,feedback is needed and the crank angle of 50% burnt (CA50) has provedt

Anatomy and systematics of usneoid genera in the Parmeliaceae.

The anatomy of 11 genera earlier included in the Usneaceae, i.e. Bryocaulon Karnef., Chondropsis NyI., Cornicularia Hoffm., Evernia Ach., Everniopsis Nyl., Himantormia Lamb, Letharia (Th. Fr.) Zahlbr., Lethariella (Mot.) Krog, Protousnea (Mot.) Krog, Pseudevernia Zopf and Usnea Adanson have been examined. Particular emphasis has been paid to the development of the apothecia and the formation of a

Documentation quality in occupational therapy patient records: Focusing on the technical aid prescription process

In order to plan for and implement research on the outcome of the technical aid prescription process, more knowledge about the documentation of the process is imperative. The overarching aim of this study was to survey documentation quality aspects in patient records in community-based OT, with a particular focus on the technical aid prescription process. An additional aim was to compare the quali

Appearance of intramolecular high-frequency vibrations in two-dimensional, time-integrated three-pulse photon echo data

An alternative experimental outline to measure homodyne detected three-pulse photon-echo data is presented. The novel experimental approach allowing for online monitoring and correction of experimental timing and stability is discussed in detail using the paradigm system of Nile blue in alcohol solution. It is shown that excellent signal-to-noise ratios together with high reproducibility of the da
