The City

City centers have to cope with an increasing amount of air pollution. The supply of fresh air is crucial yet difficult to ensure, especially under stable conditions of the atmospheric boundary layer. This case study used the PArallelized Large eddy simulation (LES) Model PALM to investigate the wind field over an urban lake that had once been built as a designated fresh air corridor for the city center of Münster, northwest, Germany. The model initialization was performed using the main wind direction and stable boundary layer conditions as input. The initial wind and temperature profiles included a weak nocturnal low-level jet. By emitting a passive scalar at one point on top of a bridge, the dispersion of fresh air could be traced over the lake’s surface, within street canyons leading to the city center and within the urban boundary layer above. The concept of city ventilation was confirmed in principle, but the air took a direct route from the shore of the lake to the city center above a former river bed and its adjoining streets rather than through the street canyons. According to the dispersion of the passive scalar, half of the city center was supplied with fresh air originating from the lake. PALM proved to be a useful tool to study fresh air corridors under stable boundary layer conditions.

Megalithic Tombs

Till 1948 the coherent record of farming in Northern Europe began with the neolithic culture represented in the Danish dysser (‘dolmens’) and most readily defined by the funnel-necked beakers, collared flasks and ‘amphorae’ found therein. As early as 1910 Gustav Kossinna had remarked that these distinctive ceramic types, and accordingly the culture they defined, were not confined to the West Baltic coastlands, but recurred in the valleys of the Upper Vistula and Oder to the east, to the south as far as the Upper Elbe and in northwest Germany and Holland too. He saw in this distribution evidence for the first expansion of Urindogermanen from their cradle in the Cimbrian peninsula. In the sequel Åberg filled in the documentation of this expansion with fresh spots on the distribution map and Kossinna himself distinguished typologically four main provinces or geographical groups—the Northern, Eastern, Southern and Western. Finally Jazdrzewski gave a standard account of the whole content of what had come to be called Kultura puharów lejkowatych, Trichterbecherkultur, or Tragtbaegerkulturen. As ‘Funnel-necked-beaker culture’ is a clumsy expression and English terminology is already overloaded with ‘beakers’, I shall use the term ‘First Northern’.The orgin of this vigorous and expansive group of cultivators and herdsmen has always been an enigma. Not even Kossinna imagined that the savages of the Ertebølle shell-mounds spontaneously began cultivating cereals and breeding sheep in Denmark. As dysser were regarded as megalithic tombs and as megaliths are Atlantic phenomena, he supposed that the bases of the neolithic economy were introduced from the West together with the ‘megalithic idea’. But the First Northern Farmers of the South and East groups did not build megalithic tombs. Moreover, in the last ten years an extension of the North group across southern Sweden as far as Södermannland has come to light, and these farmers too, though they used collared flasks and funnel-necked beakers, built no dolmens either. In any case there was nothing Western about the pottery from the Danish dysser, and Western types of arrow-head are conspicuously rare in Denmark.

Abstract Objectives The intima-media thickness of the common carotid artery (ccIMT) is an established risk marker for cardiovascular disease (CVD). However, it is unclear whether lifestyle interventions can easily demonstrate an improvement in ccIMT. The objective was to test if our intervention would beneficially affect ccIMT (among other CVD markers). Design Non-randomized controlled trial Setting Rural northwest Germany Participants Middle-aged and elderly participants from the general population (intervention: n = 114; control: n = 87) Intervention A community-based, 6-month controlled lifestyle intervention focusing on four areas of lifestyle change: a plant-based diet, physical activity, stress management, and an improved social life. A strong emphasis was on dietary change. Measurements We tested whether ccIMT change from baseline to 6 months was different between groups. Results With all participants included, no significant difference in mean ccIMT change between groups was observed (p = 0.708). However, in a subgroup analysis with participants with high baseline mean ccIMT (≥0.800 mm) a significant difference in mean ccIMT change between intervention (−0.023 [95% CI −0.052, 0.007] mm; n = 22; baseline mean ccIMT: 0.884 ± 0.015 mm) and control (0.041 [95% CI 0.009, 0.073] mm; n = 13; baseline mean ccIMT: 0.881 ± 0.022 mm) was observed (p = 0.004). Adjusting for potential confounders did not substantially alter the results. Conclusion The results indicate that healthy lifestyle changes can beneficially affect ccIMT within 6 months and that such a beneficial effect may be more easily demonstrated if participants with high baseline ccIMT are recruited. The observed effect is of relevance for the prevention of CVD events, including myocardial infarction and stroke.

Introduction: The prevalence of obesity is high and increasing worldwide. Obesity is generally associated with an increased risk of chronic disease and mortality. The objective of the study was to test the effect of a lifestyle intervention on body weight and other chronic disease risk markers. Methods: A non-randomized controlled trial was conducted, including mostly middle-aged and elderly participants recruited from the general population in rural northwest Germany (intervention: n = 114; control: n = 87). The intervention consisted of a 1-year lifestyle programme focusing on four key areas: a largely plant-based diet (strongest emphasis), physical activity, stress management, and community support. Parameters were assessed at baseline, 10 weeks, 6 months, and 1 year. The control group received no intervention. Results: Compared to control, in the intervention group significantly lower 1-year trajectories were observed for body weight, body mass index (BMI), waist circumference, total cholesterol, calculated LDL cholesterol, non-HDL cholesterol, remnant cholesterol (REM-C), glucose, HbA1c, and resting heart rate (RHR). However, between-group differences at 1 year were small for glucose, HbA1c, and cholesterol (apart from REM-C). No significant between-group differences were found for 1-year trajectories of measured LDL cholesterol, HDL cholesterol, triglycerides, insulin, blood pressure, and pulse pressure. Conclusion: The intervention successfully reduced body weight, BMI, waist circumference, REM-C, and RHR. However, at 1 year, effectiveness of the intervention regarding other risk markers was either very modest or could not be shown.
