The purposes of this study were: 1) to investigate the anaerobic energy contribution during a simulated cross-country (XC) skiing mass-start competition while roller-ski skating on a treadmill; 2) to investigate the relationship between the recovery of the anaerobic energy reserves and performance; and 3) to compare the gross efficiency (GE) method and maximal accumulated oxygen deficit (MAOD) to ...

Terrestrial laser scanning (TLS) provides a means of rapid and highly accurate survey of archaeological excavations and structures at landscape scales, and is particularly valuable for documenting tidal environments. Here, the authors use TLS to record tidal fixed fishing structures and a tide mill within the Léguer Estuary at Le Yaudet, in north-west France. As part of a comprehensive resource-exploitation ...

Although the ability to sprint repeatedly is crucial in road cycling races, the changes in aerobic and anaerobic power when sprinting during prolonged cycling has not been investigated in competitive elite cyclists. Here, we used the gross efficiency (GE)-method to investigate: (1) the absolute and relative aerobic and anaerobic contributions during 3 × 30-s sprints included each hour during a 3-h ...

Terraces are highly productive, culturally distinctive socioecological systems. Although they form part of time/place-specific debates, terraces per se have been neglected – fields on slopes or landscape elements. We argue that this is due to mapping and dating problems, and lack of artefacts/ecofacts. However, new techniques can overcome some of these constraints, allowing us to re-engage with ...

Advances in neonatology have led to improved survival for periviable infants. Immaturity still carries a high risk of short- and long-term harms, and uncertainty turns provision of life support into an ethical dilemma. Shared decision-making with parents has gained ground. However, the need to start immediate life support and the ensuing difficulty of withdrawing treatment stands in tension with the ...

Metagenomics can generate data on the diet of herbivores, without the need for primer selection and PCR enrichment steps as is necessary in metabarcoding. Metagenomic approaches to diet analysis have remained relatively unexplored, requiring validation of bioinformatic steps. Currently, no metagenomic herbivore diet studies have utilized both chloroplast and nuclear markers as reference sequences ...

Mining and processing of minerals produce large quantities of tailings as waste. Some countries, including Norway, allow disposal of mine tailings in the sea. In this study we investigated the impacts of tailings from a calcium carbonate (CaCO3) processing plant on early live stages of haddock (<i>Melanogrammus aeglefinus</i>) and Atlantic cod (<i>Gadus morhua</i>). Fish eggs (3 days post fertilisation; ...

Improving the operational energy efficiency of existing ships is attracting considerable interests to reduce the environmental footprint due to air emissions. As the shipping industry is entering into Shipping 4.0 with digitalization as a disruptive force, an intriguing area in the field of ship’s operational energy efficiency is big data analytics. This paper proposes a big data analytics framework ...

This article examines how two devising theater projects with 43 seventh grade pupils respond to values in adaptive education: inclusion, appreciation, variation, experience, relevance, context, and participation. We focus on statue work and the formation of ideas through negotiation processes. The project responds to and concretizes democratic working methods and a pupil perspective in adaptive ...

Cross-country (XC) skiers employ whole-body exercise to generate speed through poles and skis. The choice of optimal pole and ski lengths are therefore of high importance. The aim of this study was to document pole and ski lengths among elite male and female cross-country skiers in the classical and skating styles and to investigate sex differences in body-height-normalized pole and ski lengths. Our ...
