Temporal disturbance of a model stream ecosystem by high microbial diversity from treated wastewater

open access: yesMicrobiologyOpen, 2023
Microbial communities in freshwater streams play an essential role in ecosystem functioning via biogeochemical cycling. Yet, the impacts of treated wastewater influx into stream ecosystems on microbial strain diversity remain mostly unexplored.

Resilience: Safety in the Aftermath of Traumatic Stressor Experiences

open access: yesFrontiers in Behavioral Neuroscience, 2020
The relationship between adverse experiences and the emergence of pathology has often focused on characteristics of the stressor or of the individual (stressor appraisals, coping strategies).

The impact of inundation and sandstorms on the growth and survival of the mangrove Avicennia marina seedlings in the southern Red Sea

open access: yesScientia Marina, 2022
Mangroves occur in tropical and subtropical regions, including harsh arid areas. Little is known about how the environmental conditions of deserts influence the ecology of mangrove seedlings.

Association between changes in heart rate variability during the anticipation of a stressful situation and the stress-induced cortisol response [PDF]

open access: yes, 2018
Vagal activity - reflecting the activation of stress regulatory mechanisms and prefrontal cortex activation - is thought to play an inhibitory role in the regulation of the hypothalamus-pituitary-adrenal axis.

A Better Understanding of Bee Nutritional Ecology Is Needed to Optimize Conservation Strategies for Wild Bees—The Application of Ecological Stoichiometry

open access: yesInsects, 2018
The observed decline in wild bees may be connected to the decreasing diversity of flowering plants. Changes in floral composition shape nutrient availability in inhabited areas, and bee larvae need food rich in body-building nutrients to develop into ...

THE COLD PRESSOR TEST – A MEASUREMENT OF THE CARDIAC AUTONOMIC RESPONSES IN INDIVIDUALS WITH ANXIETY, DEPRESSION AND STRESS SYMPTOMS [PDF]

open access: yesTrakia Journal of Sciences, 2020
The cold pressor test examines the cardio-vascular reactivity during certain physiological states - rest, stress and recovery. Currently it is a widespread tool for laboratory induced stress in an experimental setting amongst various fields of science ...

Effects of salinity changes on aquatic organisms in a multiple stressor context

open access: yesPhilosophical Transactions of the Royal Society of London. Biological Sciences, 2018
Under global change, the ion concentration of aquatic ecosystems is changing worldwide. Many freshwater ecosystems are being salinized by anthropogenic salt inputs, whereas many naturally saline ones are being diluted by agricultural drainages.

Reliability improvement of electronic circuits based on physical failure mechanisms in components [PDF]

open access: yes, 1991
Traditionally the position of reliability analysis in the design and production process of electronic circuits is a position of reliability verification. A completed design is checked on reliability aspects and either rejected or accepted for production.
