Precision agriculture represents a promising technological trend in which governments and local authorities are increasingly investing. In particular, optimising the use of pesticides and having localised models of plant disease are the most important goals for the farmers of the future. The Trentino province in Italy is known as a strong national producer of apples. Apple production has to fac...
OBJECTIVES The aim of this study was to test whether human leukocyte antigen (HLA) polymorphism contributes to the physical constitutions classified in Traditional Chinese Medicine (TCM). DESIGN Seven hundred six (706) individuals of the Han ethnic group inhabiting South China were classified into 7 TCM constitution groups, according to the criteria described in Theories of Physical Constitut...
The comparison of four dynamic systems-based software packages: Translation and sensitivity analysis
Dynamic model development for describing complex ecological systems continues to grow in popularity. For both academic research and project management, understanding the benefits and limitations of systems-based software could improve the accuracy of results and enlarge the user audience. A Surface Wetness Energy Balance (SWEB) model for canopy surface wetness has been translated into four soft...
A considerable portion of Canada’s landmass is covered by grassland ecosystems. Insight into the grassland spatial heterogeneity will not only contribute to better understanding of the scale dependent ecological processes but will also help in management and monitoring. Leaf area index (LAI) is a key structural attribute of grassland that reflects primary production. It is well-known that topog...
Climate model projections suggest widespread drying in the Mediterranean Basin and wetting in Fennoscandia in the coming decades largely as a consequence of greenhouse gas forcing of climate. To place these and other "Old World" climate projections into historical perspective based on more complete estimates of natural hydroclimatic variability, we have developed the "Old World Drought Atlas" (...
Supported metal nanoparticle catalysts are commonly obtained through deposition of metal precursors onto the support using incipient wetness impregnation. Typically, empirical relations between metal nanoparticle structure and catalytic performance are inferred from ensemble averaged data in combination with high-resolution electron microscopy. This approach clearly underestimates the importanc...
In the last years satellite remote sensing applications in hydrology have considerably progressed. A new multi-temporal satellite data-analysis approach has been recently suggested in order to estimate space-time changes of geophysical parameters possibly related to the increase of environmental and hydro-geological hazards. Such an approach has been already used both for flooded area mapping (...
This work presents the design and implementation of a wireless sensor network (WSN) from first principles, i.e. without the use of commercial WSN platforms. Specifically, a modular multi-hop WSN was built for humidity, temperature and soil wetness measurements, towards precision agriculture applications. We describe the modules developed for radio communication, low-cost sensing, relaying and s...
