ions/ Intangibles činŭ rank, sanŭ rank, darŭ gift, rodŭ clan, grěxŭ sin, polŭ half, mirŭ peace Associated with Czech, Polish, and Russian Gsg -u and Lsg -u We will focus our attention on the short-u-stem endings that survived the collapse of their paradigm. The few nouns that were associated with the old short-u-paradigm were absorbed into the o-stem masculine paradigm, but retain...
the aim of this paper is eliminating cr(vi) by natural hap. hap is a inexpensive material which is used from bovine critical bone ash in order to remove heavy metal ions like cr(vi). some experiments in different ph are performed (ph=2,3,7). maximum adsorption was appeared at ph=2, dosage=0.3 gr, c0=10 mg/l. cr(vi) removal depends on ph value and initial amount of cr(vi) result of experiments w...
Our increasingly urbanized society and our technology-mediated lifestyles distance most of us from the biological and non-human physical world. Environmental problems present a challenge for education and outreach because they are inherently complex, interdependent, and interrelated. The need for environmentally literate citizens has never been greater. We need people who can work toward an eco...
1. Understanding and accurately predicting the spatial patterns of habitat use by organisms is important for ecological research, biodiversity conservation and ecosystem management. However, this understanding is complicated by the effects of spatial scale, because the scale of analysis affects the quantification of species-environment relationships. 2. We therefore assessed the influence of en...
Developmental, learning, and behavioral disabilities are a significant public health problem. Environmental chemicals can interfere with brain development during critical periods, thereby impacting sensory, motor, and cognitive function. Because regulation in the United States is based on limited testing protocols and essentially requires proof of harm rather than proof of lack of harm, some un...
Stochasticity alters the nonlinear dynamics of inherently cycling populations. The power spectrum can describe and explain the impacts of stochasticity. We fitted models to short observed time series of flour beetle populations in the frequency domain, then used a well fitting stochastic mechanistic model to generate detailed predictions of population spectra. Some predicted spectral peaks repr...
We cannot "imagine a visual or auditory event that is nonspatial or atemporar' (Handel, 1988, p. 315); this statement either begs the question or is false. He claims that people mentally transform space and time in both modalities; I argue that we never mentally transform auditory space but often transpose in pitch and translate in time. Handel claims that all other "modality translations," inc...
Sustainable development is an environmental concept appropriate to our era that nowadays in all of economic, social, environmental and physical-spatial aspects is considered and focused by everyone. In these times, global organizations that are working around the issues of sustainable development, emphasis on rural sustainable development, which seeks to improve rural living standards and welf...
