The paper presents the results of determinations of heavy metals (Cd, Cr, Cu, Ni, Pb and Zn) in 24 samples of bottom sediments collected in six gauging cross-sections along the course of the Mała Wełna river (western Poland). The samples were collected once a month from May to August 2006. The determinations were made separately in the following granulometric fractions: >2.0, 2.0-1.0, 1.0-0.5, 0.5-0.25, 0.25-0.1, 0.1-0.063, and <0.063 mm, using 3M HCl as the extraction agent. The concentrations of the heavy metals studied were lowest in the 0.5-0.25 and 0.25-0.1 mm fractions, and the highest in the 0.1-0.063 and <0.063 mm fractions, and also in the larger fraction. The determinations were made using atomic absorption spectrometry with flame atomization (F-AAS).

The water conductivity of arctic zone soils derived in different micro-relief forms was determined. The greatest water conductivity at the 0-5 cm depth for the higher values of water potentials (> -7 kJ m-3) was shown by tundra polygons (Brunic-Turbic Cryosol, Arenic) – 904-0.09 cm day-1, whereas the lowest were exhibited by Turbic Cryosols – 95-0.05 cm day-1. Between -16 and -100 kJ m-3, the water conductivity for tundra polygons rapidly decreased to 0.0001 cm day-1, whereas their decrease for the other forms was much lower and in consequence the values were 0.007, 0.04, and 0.01 cm day-1 for the mud boils (Turbic Cryosol (Siltic, Skeletic)), cell forms (Turbic Cryosol (Siltic, Skeletic)), and sorted circles (Turbic Cryosol (Skeletic)), respectively. In the 10-15 cm layer, the shape of water conducti-vity curves for the higher values of water potentials is nearly the same as for the upper layer. Similarly, the water conductivity is the highest – 0.2 cm day-1 for tundra polygons. For the lower water potentials, the differences in water conductivity increase to the decrease of soil water potential. At the lowest potential the water conductivity is the highest for sorted circles – 0.02 cm day-1 and the lowest in tundra polygons – 0.00002 cm day-1.

The sediments of the beaches along the central coast of Tamil Nadu from Pondicherry to Vedaranyam were studied for their textural variation. 108 sediment samples collected from the low-, mid-, and high-tidal zones, as well as the berms and dunes of different beach morpho-units were analysed. The study area was divided into three sectors (northern, central and southern) on the basis of prevailing energy conditions and oceanographic parameters. The poorly sorted, negatively skewed, coarser sediments of the northern sector are indicative of denudational processes taking place there. Medium-to-fine, moderately-to-well sorted, positivesymmetrically skewed sediments dominate the central sector, probably as a result of the influence of palaeo-sediments deposited by rivers from inland as well as by waves and currents from offshore. Fine, poorly sorted, positive-symmetrically skewed sediments dominate the southern sector, highlighting depositional processes. Linear Discriminant Function Analysis (LDF) of the samples indicates a shallow marine environment origin for all the three sectors. These results show that reworked sediments, submerged during the Holocene marine transgression, are being deposited on present-day beaches by waves, currents and rivers in the study area.

The paper presents a lithodynamic interpretation of the Polish-Russian morpholog- ical and lithological research project along the marine coastal zone of the Vistula Spit, carried out between July and September 2008. 78.4% of the coastal zone is characterized by a balanced environment, with fractional transport of sediments as bed and suspended load. Deposition was observed in 8.2% of the study area. A dynamic environment with a deficit of bed material, local turbulences and erosive trends were found in 13.2% of the coastal zone. The critical erosive current velocities vary from 16 to 20–26 cm s−1.

This paper present information on particle size variation during rainfall and snowmelt flood from the small agricultural catchment. The grain size distribution during two rainfall, three snowmelt and one rainfall-snowmelt flood was compared. The average percentage of clays size material (<4 µm) for all samples was 2.7%, silt size material (> 4 µm and <62 µm) was 42.8% and sand (>62 µm) was 54.5%. The average median (d50) for floods ranged between 49.8 microns and 98.3 microns depend on the flood.

Materiałem badawczym była natywna skrobia ziemniaczana, rozfrakcjonowana na 2 frakcje o wymiarach 1-50 µm i 51-100 µm. Obydwie frakcje skrobi poddano analizie mikroskopowej w świetle spolaryzowanym i zwykłym, a także badaniom lepkości (wiskozymetr Brabendera i Hoepplera ) i zdolności do retrogradacji. Stwierdzono, że duże ziarna skrobi szybciej przechodzą w fazę koloidalną, dając kleiki o mniejszym maksimum lepkości. Badania podatności skrobi na α-amylolizę wykazały, że skrobia o dużych ziarnach łatwiej ulega hydrolizie, natomiast po kilkakrotnym zamrażaniu i rozmrażaniu kleików skrobia ta wykazywała większą odporność na działanie α-amylazy, a więc w większym stopniu ulegała procesom retrogradacji niż skrobia o małych ziarnach.

Grain size studies of sediments from beaches in the region from Mandapam to Kanyakumari, divided into 5 sectors, indicate that sediments are unimodal to polymodal in nature, coarse to fine grained, moderately to poorly sorted, and positively-negatively skewed in character. The inference to be drawn from these studies is that the variation in sedimentological parameters is governed by fluvial input, wave dynamics, and littoral transport of the sediments. Bivariant plots show that the Mandapam and Kanyakumari sectors can be classified as beach environments, whereas the Tuticorin and Valinokkam sectors come under the influence of riverine environments and the dune environment in the Manappad sector. The CM pattern of all five sectors shows a clustered distribution of sediments in the PQ and QR segments, indicating a graded mode of deposition. Visher diagrams depict a wave shadow environment for the Mandapam sector, whereas the Valinokkam, Tuticorin and Manappad sectors show double saltation populations characteristic of beaches, and the Kanyakumari sector is characterized by a more truncated population characteristic of a plunge zone, which is a high-energy environment.

Skrobię ziemniaczaną rozsegregowano na frakcje dużych i małych ziaren. Skrobię wyjściową oraz uzyskane frakcje poddano fosforylacji trimetafosforanem sodu. Uzyskane preparaty przeanalizowano pod względem wybranych właściwości fizykochemicznych. Na podstawie uzyskanych wyników stwierdzono, że fosforylacja skrobi ziemniaczanej i jej frakcji spowodowała wbudowanie największej ilości fosforu do frakcji ziarenek małych w porównaniu do frakcji ziaren dużych i skrobi natywnej. Uzyskane fosforany skrobiowe charakteryzowały się mniejszą zawartością amylozy i większymi wartościami lepkości w stosunku do odpowiednich prób kontrolnych. Fosforan skrobiowy otrzymany z frakcji małych ziaren skrobi ziemniaczanej odznaczał się mniejszą zawartością amylozy i większą lepkością kleiku w odniesieniu do fosforanów uzyskanych ze skrobi natywnej i frakcji ziaren dużych.
