But some private environmental groups pointed out that the findings raised questions about how to set the appropriate limits for chemicals, particularly because they can interact when combined in unpredictable ways.
Such challenges combined with unpredictable rainfall and changing temperature (Campbell et al. 2005; Sandford 2006) leave villagers vulnerable to economic disasters.
The large variability in energy consumption in the EPS combined with unpredictable weather events can lead to a situation in which, to save the stability of the EPS, power limits must be introduced or even industrial customers in a given area have to be disconnected, which causes financial losses.
"Drier, longer summers combined with unpredictable wet winters have created dangerous fire conditions".
To evaluate the feasibility of focal cerebral ischemia and reperfusion (FCIR) surgery combined chronic unpredictable mild stress (CUMS) to simulate the post-stroke depression (PSD) state in rats.
As limbs sprout in unnatural profusion and the human blueprint combines in unpredictable ways with flora and fauna, monsters test the limits that define who we are, that distinguish the self from that which belongs to the other.
The heat and dust of the battlefield, combined with the unpredictable nature of the chemistry, made it particularly taxing, but with patience and practice, Drew had success.
However, these probes are typically time-consuming and challenging to prepare (Fig. 2), and this, combined with the unpredictable nature of biological systems that necessitates a heuristic approach to probe optimisation, presents a significant barrier to their application.
Chronic unpredictable stress combined with isolation rearing was applied on rats for three weeks, except for control group.
Chronic unpredictable stress combined with isolation rearing was applied in rats of stressed group for three weeks.
