Late Holocene environmental history of Dojran, Macedonia: Investigating the interplay of imperial dynamics and climatic change

Journal of Quaternary Science, EarlyView.
ABSTRACT This study presents a high‐resolution, multi‐proxy reconstruction of environmental and land‐use change from Lake Dojran over historical times (last 2500 years), combining pollen, biomarkers, radiocarbon dating, Ottoman taxation records and other historical data.

Co-simulation for real time safety verification of nuclear power plants

Mechanical Engineering Journal, 2017
Small and major accidents and near misses are still occurring in nuclear power plants (NPPs). Risk level has increased with the degradation of NPP equipment and instrumentation.

Holocene vegetation change and fire–plant diversity shifts in Mediterranean France

Journal of Quaternary Science, EarlyView.
ABSTRACT Changes in fire activity are recognized as a major threat to biodiversity and vegetation communities across the Mediterranean Basin. However, long‐term fire–vegetation interactions remain poorly investigated. Here, we combine a high‐resolution charcoal record with pollen data from the “Étang des Aulnes” lake (southern France) to reconstruct ...

Assessing the spatio-temporal variability of vegetation productivity in Africa: quantifying the relative roles of climate variability and human activities

International Journal of Digital Earth, 2017
Quantitative attribution at the individual pixel level of the relative contributions of climate variability and human activities to vegetation productivity dynamics across Africa is generally lacking.

‘The most advanced outpost of cultivation’: palynological evidence for cereal agriculture and population resilience in a marginal upland environment

Journal of Quaternary Science, EarlyView.
ABSTRACT Upland farming in Europe is frequently assumed to have been limited and precarious, despite relict spade‐dug ridges providing firm evidence of past crop growing. Direct evidence for crop types in post‑Medieval to Modern (~since 1500 CE) uplands is rare; yet, in Ireland, relict spade‐dug ridges that date to this period are commonly interpreted ...

اثر بلوک گانگلیونی بر فشارخون و ضربان قلب ناشی از تزریق پروتئین جدید افزاینده فشارخون (NPP) در موش های صحرایی نفرکتومی شده [PDF]

مجله دانشگاه علوم پزشکی سبزوار, 1970
زمینه و هدف: NPP (پروتئین جدید افزاینده فشار خون) یک آنزیم پلاسمایی انسانی و از نظر ساختمانی وابسته به b-FXIIa است که به طور شدیدی فشار خون سیستولیک (SBP)، فشارخون دیاستولیک (DBP) و ضربان قلب (HR) را در موش های صحرایی افزایش می دهد.

The Relationship Between Human Activities and Ecosystem Service Supply–Demand From the Perspective of Land Use Transformation

Land Degradation &Development, EarlyView.
ABSTRACT The equilibrium between ecosystem service supply and demand relationships (ESSDR) is essential for regional sustainable development. Understanding the relationship between human activity intensity (HAI) and ESSDR from the perspective of land use transformation (LT) is important for ecological management and governance.

Spatially Heterogeneous and Nonlinear Responses of Ecosystem Service Value to Human Activity Intensity in an Arid Mountain–Oasis–Desert Urban Agglomeration

Land Degradation &Development, EarlyView.
ABSTRACT Rapid urbanization and agricultural expansion are reshaping human–environment relationships in arid regions; however, the spatially heterogeneous and nonlinear relationships between human activities and ecosystem services remain insufficiently understood.
