Wind flats are typical coastal landscape elements of the tide-less Southern Baltic Sea. These sediment areas exhibit an irregular and unpredictable pattern of emersion and flooding as a function of the prevailing wind direction and speed. Consequentl

The investigation of processes of particle exchange and transport using filtration sampler, bottom water sampler, sediment traps, or other equipment is one important task in marine research. In this paper, we describe a modular hardware solution (mic

The atomic-scale structure of materials with different degrees of structural disorder has been investigated by high-energy (E⩾60 keV ) X-ray diffraction. Good quality structure functions extended to wave vectors of magnitude Q⩾40 A −1 have been

Patients with chronic fatigue syndrome (CFS) frequently associate the disease onset with a period of high physical and/or emotional stress. Alterations in hypothalamic-pituitary adrenal axis (HPA) function have been demonstrated. Although Cortisol pr

Extended structure factors for ${\mathrm{Ca}}_{x/2}{\mathrm{Al}}_{x}{\mathrm{Si}}_{1\ensuremath{-}x}{\mathrm{O}}_{2}$ glasses (x=0,0.34,0.5,0.68) have been obtained by energy-dispersive x-ray diffraction. The first neighbor Si-O and Al-O interatomic

Amorphous TiO2 materials, layers and powders, have been produced by different preparation techniques. The layers have been subjected to electron diffraction and the bulk powders to X-ray diffraction experiments. Three-dimensional structure models con

The submicron structures of two natural hydrous forms of silica (geyserites from Iceland, hyalite from Valec CS) have been studied by scanning electron microscopy, small-angle and wide-angle X-ray scattering. All geyserites investigated are particula

Low-density x SiO 2 -(1 - x )Al 2 O 3 aerogels with x = 0, 0.3, 0.7, 1.0 (mole fractions) were prepared by CO 2 supercritical drying of alkogels formed from Si(OMe) 4 and Al(OBu s ) 3 by hydrolytic polycondensation under different chemical conditions
