Physics in daily life: seeing under water

in the treatment, there are interesting results that indicate that the singularity problem of classical general relativity would be resolved due to the fundamental discreteness predicted by LQG ... . Another important open issue in LQG is the semiclassical limit: how to recover from the fundamental polymer-like excitations of LQG the smooth physics of general relativity and the standard model at low

Reversible Thermoassociation of Water-Soluble Polymers

In various industrial fields, water soluble polymers are commonly used as thickening agents to control the reology of aqueous fluids. Nevertheless, their properties are weakened as the temperature ... weakened as the temperature increases. In order to overcome this problem, the concept of “ther­ moassociative”water soluble polymers was developed. Such new amphilic systems can be obtained by grafting on an

Water quality management through community engagement in Costa Rica

Concerns about stream water quality are increasing in Latin America. Poor sanitation infrastructure coupled with a high demand from agricultural development, recreational use, drinking, and ... involvement, along with a water quality index useable by the general public, was a key to the overall success of the project.

Liana and tree below-ground water competition—evidence for water resource partitioning during the dry season

dual stable water isotope approach (δ18O and δ2H) enables below-ground vegetation competition for water to be studied. Based on the occurrence of a natural gradient in soil water isotopic signatures ... more general trait for lianas than for trees has never been studied. Further research on this topic is greatly needed and should be considered in view of the presented findings. Seasonality in water use

DNA methylation and histone acetylation: genotypic variations in hybrid poplars, impact of water deficit and relationships with productivity

of epigenetic modifiers, their possible correlations with morphological traits and the impact of water deficit have not been described for perennial plants.• Six genotypes of Populus deltoides × P ... general decrease of most of these morphological traits was recorded. The leaf variables adjustment ensures a reduction of water losses but affects the photosynthesis activity and consequently the biomass

Multiresidue solid-phase extraction for trace-analysis of pesticides and their metabolites in environmental water

fairly soluble in water and are therefore less amenable to solvent extraction. Automation and new trends in SPE The solid-phase extraction (SPE) area has been very active these past years, certainly due ... observed when handling water containing suspended solids such as surface water. Various approaches have been developed to solve this problem. One consists in depth filters which can be placed above the

Feasibility of 15O-water PET studies of auditory system activation during general anesthesia in children

not able to cooperate during scanning. Therefore, we evaluated retrospectively results of individual SPM (statistical parametric mapping) analysis of 15O-water PET in 17 children studied during general ... auditory cortex activations in 15O-water PET during general anesthesia. Combined with the improved signal to noise ratios of modern PET scanners, this suggests reasonable prospects for further evaluation of

Macromolecular source as dependent on osmotic pressure and water source: effects on bovine in vitro embryo development and quality

study evaluated the protective effect of protein, as dependent on osmolarity, and the quality of water sources used to prepare embryo culture media. In Experiment 1, two concentrations of NaCl were used ... (P < 0.05), while trophectoderm (TE) and total cell counts tended to decrease (P < 0.08). In Experiment 2, culture media were prepared with two water sources (Milli-Q and Sigma-W3500-) in combination

Dirty Water: ‘Nuremberg’ and Film

advertisements in the restaurants at that time did you not conclude that the social contact between the Jews and Aryans in general was undesirable?. . . Irene Seiler: I could not as a human being imagine such a ... German chancellor at the time, Konrad Adenauer, reportedly said, ‘One does not throw out dirty water so long as one does not have any clean water.’36 Looking back on this now, toleration of the ‘dirty

Water, Forests, People: The Swedish Experience in Building Resilient Landscapes

A growing world population and rapid expansion of cities increase the pressure on basic resources such as water, food and energy. To safeguard the provision of these resources, restoration and ... -structured discussions aiming to clarify and emphasize the interconnections between forests and water in general and particularly to identify key features in Swedish forestry practices and governance that

Mine Water Problems and Solutions in China

research should not be limited to mine water professionals. The general public should be encouraged to participate in this campaign. Citizen science is an essential supplement to professional science (Li et ... feasible and flexible solutions to them (Wu et al. 2014). This special issue has enabled some of China's mine water researchers to share their results and practical experience globally. Vol.:(011233456789

The views of the general public on prioritising vaccination programmes against childhood diseases: A qualitative study

Objective To gauge the general public’s preferences for prioritising certain ... analysed using an inductive thematic framework approach. Setting Population Adult members of the general public were recruited using the Bristol and South Gloucestershire open electoral registers, using

Priestley’s views on the composition of water and related airs

indications about his late work from 1788 onwards and his late phlogistic theory, of which there has not been a detailed study. This paper undertakes a detailed study of Priestley’s late work on water and ... section examines separate topics in Priestley’s work on water and related airs in detail and in context. The following section discusses Priestley’s general complaints against the Lavoisians in the light of
