The R package iBluff is designed for coastal bluffs/bluffs morphological analysis and offers an automatic reproducible alternative to identify bluff edges using a bare earth digital elevation model (DEM) instead of hand digitizing. This extracts profiles along automatically identified transects on the bluff-face, top, toe, secondary inflections, relative concavity/convexity beach dunes (crests ...

Hand-held technologies have offered less support for learning about space and measurement than they have for other strands of mathematics. This paper describes a recent development which seems promising in this respect, Casio’s ClassPad 300. The mechanisms of providing interactive opportunities for students are described and illustrated, and some possible ways in which this sort of device might...

Mangroves are transitional ecosystems between terrestrial and marine environments, and are dis- tinguished by a high abundance of animals, plants, and fungi. Although macrofungi occur in different types of habitat, including mangroves, little is known about their community structure and dynamic. Therefore the aim of this study was to analyze the diversity of macrofungi in a number of Brazilian ...

The key to successful innovative development of the Republic Uzbekistan is formation new high-tech industries, upgrading technical and technological nature, input modern facilities, expansion production volume, ready compete, increase in exports parallel with filling domestic market finished products high added value. an attractive place for investment, due a wide sales developed transport infr...

In GdFeCo/Ir/GdFeCo heterostructures with amorphous GdFeCo layers, three critical points were found in the temperature dependences of magnetization. neighborhood 100 K, compensation for magnetizations Gd and FeCo sublattices is observed, which form a magnetization minimum does not depend on magnetic field. As decreases, sharp stepwise transition corresponds to switching mutual magnetization's o...

With uranium rich skeletons and density bands similar to their surface coral counterparts, deep-sea scleractinia are a promising archive of past climate. To improve the utility of fossil samples as monitors of deep ocean variability, we have measured Pb and Ra activities in a variety of modern specimens to constrain the range of growth rates. Mechanical and chemical cleaning of each sample are ...

Transparent Exopolymer Particles (TEP) are relevant in particle and carbon fluxes in the ocean, and have economic impact in the desalination industry affecting reverse osmosis membrane fouling. However, general models of their occurrence and dynamics are not yet possible because of the poorly known co-variations with other physical and biological variables. Here, we describe TEP distributions i...

The main objective of this paper is to study the Euclidean displacement of a 5-DOF parallel mechanism performing three translation and two independent rotations with identical limb structures-recently revealed by performing the type synthesis-in a higher dimensional projective space, rather than relying on classical recipes, such as Cartesian coordinates and Euler angles. In this paper, Study's...

abstract soil invertebrate and their spatial pattern are affected strongly by environmental factors. spatial variability of soil properties is one of the most important reasons of the macrofauna variability. this study was conducted to investigate the spatial variability of soil properties and soil macrofauna biomass in the riparian forest landscape of karkhe river. soil macro fauna were sample...
