Effects of accelerated aging and seed priming treatments were studied on milk thistle seeds during germination process. Experiment was performed in a factorial based on Complete Randomized Design (CRD). Treatments were Salicylic acid concentrations (0, 500, 1000, 1500 and 2000 ppm) and accelerated aging for (0, 48, 96 and 144 hours under 45 °C and 95% humidity) with three replications. Our ...

We discuss the future evolution of the universe in the light of recent observations. The apparent luminosity vs redshift of supernovae favor an accelerating universe. However an Einstein-de Sitter critical universe should not be ruled out yet.

Color changes of wood during natural aging and during heat treatment were elucidated to determine whether they could be explained as the result of a mild thermal oxidation process at ambient temperatures. The results of kinetic analysis employing the time-temperature superposition method showed that the color changes during natural aging were mainly the result of an oxidation process. Color cha...

introduction: heavy ions are nucleus of elements of iron, argon, carbon and neon that all carry positive electrical charges. for these particles to be useful in radiotherapy they need to accelerated to high energy by more than thousand mega volts. also the cosmic environment is considered to be a complicated mixture of highly energetic photons and heavy ions such as iron. therefore, the health ...

Halting an epidemic outbreak in its early stages requires a detailed understanding of the contact dynamics between the agents capable of carrying the pathogen. While current epidemic models assume that agents interact at a uniform rate, following a Poisson process, here we provide evidence that for several computer and biological viruses the inter contact time distribution is heavy tailed. This...

Service-based systems should be able to dynamically seek replacements for faulty or underperforming services, thus performing self-healing. It may however be the case that available services do not match all requirements, leading the system to grind to a halt. In similar situations it would be better to choose alternative candidates which, while not fulfilling all the constraints, allow the sys...

Recent research has identified men's facial width-to-height ratio (fWHR) as a reliable predictor of aggressive tendencies and behavior. Other research, however, has failed to replicate the fWHR-aggression relationship and has questioned whether previous findings are robust. In the current paper, we synthesize existing work by conducting a meta-analysis to estimate whether and how fWHR predicts ...
