Photophysiology and respiration of the temperate fern Onoclea sensibilis in spring and during summer stress in a changing climate

Onoclea sensibilis L. is a temperate fern species of horticultural importance, and widely distributed in the natural environment of North America, Eastern Europe, and parts of Asia. With increasing climate change, including excessive heat and unpredictable, sometimes severe precipitation events, ferns such as O. sensibilis may come under increasing loss of habitat and possibly survival threat. This is a study of the...

The place of education in social development and its sociological foundations

Equipping people with desired behaviors, that is, educating them, has been the most important goal throughout the ages. Today, this phenomenon is becoming more and more complex and its effect is felt more intensely. However, unless a person's behavior develops in a valid and reliable way, it is not possible to reach a longed for life style. A person can be intertwined with all kinds of processes, from the most...
