چکیده

Global warming is the leading cause of extreme meteorological events increase in last three decades. Increase annual average air temperature and values during winter early spring has been recorded comparison to (1961-1990) referent period Plovdiv region. The lettuce development was researched a greenhouse Agricultural University- Plovdiv. During growth six different variants were used: no fertilizer, one chemical, four organic fertilizers. effect fertilizers studied through specific physiological parameters productivity. This paper analyzed changes functional activity plant photosynthetic apparatus productivity with an unheated greenhouse. ratio between active radiation (PAR) quantum yield (qY-Fv/Fm) PS II determined be more optimal dark-adapted leaves for fertilizer variants, compared variant. lower significant difference observed minimal fluorescence Fo reaction centers after dark-adaptation Higher chlorophyll content index (CCI) estimated chemical All fertilized biofertilizers comply quality standard from beginning end harvesting.

Protecting the Amazon with protected areas.

This article addresses climate-tipping points in the Amazon Basin resulting from deforestation. It applies a regional climate model to assess whether the system of protected areas in Brazil is able to avoid such tipping points, with massive conversion to semiarid vegetation, particularly along the south and southeastern margins of the basin. The regional climate model produces spatially distrib...

Analysing the Effects of Flood-Resilience Technologies in Urban Areas Using a Synthetic Model Approach

Flood protection systems with their spatial effects play an important role in managing and reducing flood risks. The planning and decision process as well as the technical implementation are well organized and often exercised. However, building-related flood-resilience technologies (FReT) are often neglected due to the absence of suitable approaches to analyse and to integrate such measures in ...
