Short sediment cores from the eastern Gotland Basin were investigated using a multi-proxy approach in order to reconstruct the environmental conditions of the area during the past 1000 years. Sediment data and facies were discussed in relation to hydrographic features (salinity, oxygen) and climate change. During the medieval warm period (MWP), from about 900 to 1250 AD, the hydrographic and environmental...
This paper deals with the maintenance optimization of a system subject to a stressful environment. The behavior of system deterioration can be modified by the environment. Reciprocally, the environment condition can be influenced by the system state and so, a change in the environment can be an indicator of the system state. We propose a condition-based maintenance decision framework to tackle the...
In case of disabled people we cannot discuss full health. Depending on the type of disability, mental or physical health is affected, or both. That is why social health as a third component of health is so important. Social health is determined by the disabled persons’ ability to work in a healthy place [1, 2] The main aim of this study was to describe the scale of the unemployment among disabled...
W wielu doświadczeniach wykazano, że rozwój aparatów szparkowych jest kontrolowany przez sygnały środowiskowe takie jak wilgotność powietrza, natężenie światła czy stężenie dwutlenku węgla. Mniej prac poświęcono wpływowi jaki na morfogenezę aparatów szparkowych wywiera deficyt wody w podłożu i są to najczęściej doniesienia niejednoznaczne lub nawet sprzeczne. W doświadczeniu określono zmiany zachodzące...
The principle of cause and effect is also valid for traffic flow. But how to quantify the impact of environment conditions on traffic? A research project co-funded by the Austrian Ministry of Transport tested several methods to show dependencies and interaction between weather, events and traffic flow. This document explains the different approaches to solve the problem and summarizes that the impact...
Soil fertility is the ability of soil supply and harmonize the moisture, nutrient, air and quantity of heat needing by the plant developing, it occurs change continuously along with environment condition changes and the influence of agriculture yield action. The dynamic change of soil fertility which sampling and analyzing timely corresponding with the crop demands will be propitious to steady yield...
The objective of the study was to determine the effect of leaf wetness period and air temperature on development of disease symptoms caused by Puccinia recondita on winter wheat. The experiments were carried out in growth chamber at the Institute of Plant Protection in Poznan. Seedlings of a susceptible winter wheat cultivar Mikon, were artificially inoculated with urediniospores of P. recondita and...
