Carex divisa is a patrimonial rhizomatous species and acts as an important component of grazed wet permanent grassland on the French Atlantic coast. This study treated three storage regimes (wet-cold, dry-cold and dry-warm), burial in soil, fluctuating temperature and salinity on seed germination of C. divisa. The seeds were dormant at maturity. No seed germinated after 2 and 6 weeks of dry sto...

OBJECTIVES To evaluate the shear bond strength and site of failure of brackets bonded to dry and wet enamel. STUDY DESIGN 50 teeth were divided into ten groups of 5 teeth each (10 surfaces). In half the groups enamel was kept dry before bonding, and in the other half distilled water was applied to wet the surface after etching. The following groups were established: 1) Acid/Transbond-XT (dry/...

The wet strength of handsheets subjected to dipping treatment by solutions such as glyoxal with Zn(NO3)2 as a catalyst, chitosan, and the crosslinking system of glyoxal and chitosan is studied in this paper. The crosslinking system achieved better wet strength performance than glyoxal or chitosan alone and slightly better than the sum of glyoxal and chitosan in the case of a curing temperature ...

In this chapter, we describe a few popular experimental methodologies that can be used to independently validate the results of a microarray experiment. In contrast to many of the other chapters in this book, the techniques described here are decidedly non-mathematical or statistical in nature. Instead, most of them utilize standard 'wet-bench' molecular biology protocols that have proven thems...

A life cycle assessment of the impact of distillers grains plus solubles (DGS) on mitigation of energy and greenhouse gas (GHG) emissions comparing corn ethanol to gasoline demonstrates the importance of feeding wet DGS (WDGS) to feedlot cattle to optimize the environmental benefit of ethanol production relative to gasoline. Ethanol produced in Nebraska has a superior environmental impact compa...

A hollow cylinder apparatus was used to study some engineering properties of hollow cylindrical sand specimens prepared using the wet-pluviation technique. The refined specimen preparation method displayed good repeatability. Wet pluviation produced inherently cross-anisotropic specimens, with the level of initial anisotropy reducing with decreasing initial void ratio. The variation in the init...

The objectives of this chapter are twofold: firstly to introduce DNA computation, and secondly to demonstrate how DNA computing can be applied to solve large, complex combinatorial problems, such as the optimal scheduling of a group of elevators servicing a number of floors in a multi-storey building. Recently, molecular (or wet) computing has been widely researched not only within the context ...

We investigated the effects of recent moisture history on the relative production of N2O and N2 during denitrification in soil from cropped and successional ecosystems. The soils were pedogenically identical but had been managed differently for the past decade. Sieved soils were amended with nitrate, glucose, and water. Long-wet and short-wet incubations received 80 and 0%, respectively, of pre...

Microbial fuel cells (MFC) with 30% wet-proofed air cathodes have previously been optimized to have 4 diffusion layers (DLs) in order to limit oxygen transfer into the anode chamber and optimize performance. Newer MFC designs that allow close electrode spacing have a separator that can also reduce oxygen transfer into the anode chamber, and there are many types of carbon wet-proofed materials a...

Background: The old concept of total-etch/dry bonding has been superseded by total-etch/wet bonding, and later on by the self-etch systems. Manufacturers have introduced single bottle systems to be used in total-etch, self-etch, or selective-etch modes under both dry and moist conditions. The aim of this study was to evaluate shear bond strengths of three different dental adhesives under dry an...
