The analysis of the harmonic terms related to the rotational speed of a cup anemometer is a way to detect anomalies such as wear and tear, rotor non-symmetries (rotor damage) or problems at the output signal system. The research already done in this matter at the IDR/UPM Institute is now taken to cup anemometers working on the field. A 1-2 year testing campaign is being carried out in collaboration with Kintech Engineering. 2 Thies First Class Advanced installed at 58 m and 73 m height in a meteorology tower are constantly monitored. The results will be correlated to the anemometer performance evolution studied through several calibrations planned to be performed along the testing campaign.

The present study aimed to investigate the relationships between macronutrient intake and serum lipid profile in adolescents from eight European cities participating in the HELENA (Healthy Lifestyle in Europe by Nutrition in Adolescence) cross-sectional study (2006–7), and to assess the role of body fat-related variables in these associations. Weight, height, waist circumference, skinfold thicknesses, total choles- terol, HDL-cholesterol (HDL-C), LDL-cholesterol, TAG, apoB and apoA1 were measured in 454 adolescents (44 % boys) aged 12·5–17·5 years. Macronutrient intake (g/4180 kJ per d (1000 kcal per d)) was assessed using two non-consecutive 24 h dietary recalls. Associations were evaluated by multi-level analysis and adjusted for sex, age, maternal education, centre, sum of four skinfolds, moderate-to-vigorous.

Although the anthropometric profiles of Olympic athletes, as a group, are well known, there is still a need for specific reference data for each sport given that each discipline has its own characteristics. This study has been designed considering the limited number of articles that focus on the anthropometric characteristics of artistic roller skating and, more specifically, the figures discipline. The aim of this study is twofold: firstly, to define the anthropometric profile, body composition and somatotype of male and female artistic roller figure skaters in order to establish specific profiles; and, secondly, to establish the differences between the anthropometric profiles, body compositions and somatotypes of male and female skaters. Twenty-nine professional roller skaters (male = 15, female = 14) underwent measurements of standard anthropometry (height, body mass, arm span, 8 skinfolds, 3 breadths and 11 girths). The somatotype was measured using the Heath-Carter methods. A T-Student test for independent samples was conducted in order to assess the differences between male and female skaters. Significant statistical differences were found between male and female skaters in terms of body mass, height, arm span, the sum of four and six skinfolds and all skinfold measurements. Male skaters have a BMI of 21.4± 1.6 and female skaters have a BMI of 21.5 ± 2.4. The results indicate that arm span is an important characteristic for skaters. Mesomorphy is the most important component, followed by endomorphy, for male and female skaters. Male skaters have an endomesomorphic somatotype (3.5-4.5-2.5) and female skaters have a balanced mesomorphic somatotype (3.3-4.1-2.9).

Non-glaciated Arctic lowlands in north-east Siberia were subjected to extensive landscape and environmental changes during the Late Quaternary. Coastal cliffs along the Arctic shelf seas expose terrestrial archives containing numerous palaeoenvironmental indicators (e.g., pollen, plant macro-fossils and mammal fossils) preserved in the permafrost. The presented sedimentological (grain size, magnetic susceptibility and biogeochemical parameters), cryolithological, geochronological (radiocarbon, accelerator mass spectrometry and infrared-stimulated luminescence), heavy mineral and palaeoecological records from Cape Mamontov Klyk record the environmental dynamics of an Arctic shelf lowland east of the Taymyr Peninsula, and thus, near the eastern edge of the Eurasian ice sheet, over the last 60 Ky. This region is also considered to be the westernmost part of Beringia, the non-glaciated landmass that lay between the Eurasian and the Laurentian ice caps during the Late Pleistocene. Several units and subunits of sand deposits, peat-sand alternations, ice-rich palaeocryosol sequences (Ice Complex) and peaty fillings of thermokarst depressions and valleys were presented. The recorded proxy data sets reflect cold stadial climate conditions between 60 and 50 Kya, moderate inderstadial conditions between 50 and 25 Kya and cold stadial conditions from 25 to 15 Kya. The Late Pleistocene to Holocene transition, including the Allerød warm period, the early to middle Holocene thermal optimum and the late Holocene cooling, are also recorded. Three phases of landscape dynamic (fluvial/alluvial, irregular slope run-off and thermokarst) were presented in a schematic model, and were subsequently correlated with the supraregional environmental history between the Early Weichselian and the Holocene.
