No waters left untouched We are increasingly aware of human impacts on biodiversity across our planet, especially in terrestrial and marine systems. know less about fresh waters, including large rivers. Su et al. looked such systems globally, focusing several key measures fish biodiversity. They found that half all river have been heavily affected by activities, with only very tropical basins r...

Component-Design Architecture has been in demand based on the growing needs for modularity and flexibility automation industry. IEC 61499 standard, a component-based architecture, provides various tools techniques developers to accommodate need sequences. However, adapter concept, one of significant features remains untouched undeveloped since its inclusion standard lacks utilization true poten...

Several experimental models of osteoarthritis in rats are used to study the pathophysiology of osteoarthritis. Many mechanically induced models have the limitation that permanent joint instability is induced by, for example, ligament transection or meniscal damage. This permanent instability will counteract the potential beneficial effects of therapy. The groove model of osteoarthritis uses a o...

In natural habitats plants can be exposed to brief and light contact with neighbouring plants. This mechanical stimulus may represent a cue that induces responses to nearby plants. However, little is known about the effect of touching on plant growth and interaction with insect herbivores. To simulate contact between plants, a soft brush was used to apply light and brief mechanical stimuli to t...

Actinomycetes are a source of a broad variety of secondary metabolites with diverse biological activities, such as antifungi, antibiotics and antitumorals; many of which have been developed for clinical use. In this study, 34 actinomycetes from untouched soils were isolated from Alborz Province-Iran. Evaluation ofantifungal and anti bacterial activities of these isolates, demonstrated the capab...

In the nineteenth century, scholars trained in both mathematics and political economy began to construct economic theory in mathematical form. Over the course of the next half century, mathematical analysis gradually came to be applied, sometimes implicitly and often relegated to appendices and footnotes, in more and more parts of economic theory. Then, quite suddenly, in the years immediately ...

Salt-sensitive hypertension and chronic kidney disease (CKD) following recovery from acute kidney injury (AKI) may occur secondary to incomplete repair, or by activation of circulating factors stimulated by injury. We created two types of renal injury induced by unilateral ischemia-reperfusion (I/R); in a direct/ipsilateral AKI group, rats were subjected to unilateral I/R and the untouched cont...

1. The sodium and water excretion rates of rabbit kidneys were studied when isolated and perfused at known pressure with blood from another normal anaesthetized rabbit. Studies at several different perfusion pressures confirmed that a small rise in perfusion pressure caused a large rise in sodium excretion and that the potential sodium-excreting ability of the isolated kidney was high. The curv...
