The evidence for periods of increased volcanic activity following deglaciation, such as following ice sheet retreat after the Last Glacial Maximum, has been examined in several formerly glaciated areas, including Iceland, Alaska, and the Andean Southern Volcanic Zone. Here we present new evidence supporting the theory that during episodes of cooling in the Holocene, Icelandic volcanic activity ...

<i>Purpose</i> - The purpose of the paper is to examine the influence of consumers' perceived knowledge, knowledge discrepancy and confusion on the intention to purchase farmed fish (FF) via a survey design regarding perceptions, buying and consumption practices of urban households in Chittagong, Bangladesh.<p> <p><i>Design/methodology/approach</i> - The samples of 498 households were selected ...

The dwafshrub Empetrum nigrum uses phenolic compounds exuded by its leaves to depress the germination and growth of its surroundings. The allelopathic effect has, only been studied in areas immediately surrounding the plant (autochthonous allelopathy) but not in an open system apptoach that takes into account that a multitude of EMpetrum nigrum leaves get introduced into new environments through ...

Relevant taxonomical morphological characters of five common spring bloom centric diatoms, preliminary identified as Attheya longicornis Crawford & Gardner, Chaetoceros furcellatus Yendo, Porosira glacialis Jørgensen, Coscinodiscus sp. and Skeletonema marinoi Sarno & Zingone were observed and described using light and scanning electron microscope. Further, samples of cultured diatoms were sent to ...

Active sampling methodology for atmospheric monitoring of cyclic volatile methylsiloxanes (cVMS) was improved to reduce sampling artifacts. A new sorbent, ABN Express (ABN), was evaluated for storage stability and measurement accuracy. Storage stability of cVMS on ABN showed less than 1% degradation of the individual ¹³C-labelled octamethylcyclotetrasiloxane (¹³C₄-D4), ...

Learning compressed representations of multivariate time series (MTS) facilitates data analysis in the presence of noise and redundant information, and for a large number of variates and time steps. However, classical dimensionality reduction approaches are designed for vectorial data and cannot deal explicitly with missing values. In this work, we propose a novel autoencoder architecture based on ...

Some new multidimensional Hardy-type inequalites are proved and discussed. The cases with bilinear and iterated operators are considered and some equivalence theorems are proved.

The topic of transition curves is well known in track and road engineering. Over the years the need for easement between straight and curved sections in railway and road design has grown, with an important reason being increase in vehicle speed. Testing of transitions is often done with graph analysis where the property of lateral change of acceleration is compared between varieties of curves. ...

This thesis considers how conflicting ideas of the acceptable and unacceptable in tourism are conceptualised by tourism actors. A flexibly designed, meaning-based case study of a small-scale tourism business in a peripheral area of Finnmark is developed in successive stages. Theoretical consideration is given to tourism’s present meaning(s) relative to past understandings, and how tourism worlds can ...

Introduction: The extents of dental health issues are greater among prisoners compared to the general population. This study aimed to assess the dental services available to inmates in Norwegian prisons. Method: Electronic questionnaires were sent to 42 dentists treating inmates, and 43 prison workers. Results: Forty dentists and 38 prison workers participated in the study. 17 out of 18 ...
