Among the non-contact instruments to measure water velocity in open channels, two handheld radars are available on the market since ten years. Due to the lack of information about these instruments, one model was tested in the laboratory and in the field. The radar was able to estimate the velocity of a water surface within [p = 0.95] ± 0.3 m/s at medium velocities (from 0.3 to 3 m/s) and within ± 10 % of the measured value at large velocities (up to at least 6 m/s). Although this is not very accurate, the ease of using handheld radars still makes them attractive to quickly estimate discharge at gauging stations, safely determine water velocity during a flood and investigate how water flows under difficult access conditions. Nevertheless, the tested radar was tending to underestimate the water velocity, above all when it was looking downstream. More studies are necessary to know why. © 2014 Société Hydrotechnique de France .

Efficient cropping requires yield estimation for each involved crop, where data-driven models are commonly applied. In recent years, some data-driven modeling technique comparisons have been made, looking for the best model to yield prediction. However, attributes are usually selected based on expertise assessment or in dimensionality reduction algorithms. A fairer comparison should include the best subset of features for each regression technique; an evaluation including several crops is preferred. This paper evaluates the most common data-driven modeling techniques applied to yield prediction, using a complete method to define the best attribute subset for each model. Multiple linear regression, stepwise linear regression, M5′ regression trees, and artificial neural networks (ANN) were ranked. The models were built using real data of eight crops sowed in an irrigation module of Mexico. To validate the models, three accuracy metrics were used: the root relative square error (RRSE), relative mean absolute error (RMAE), and correlation factor (R). The results show that ANNs are more consistent in the best attribute subset composition between the learning and the training stages, obtaining the lowest average RRSE (86.04%), lowest average RMAE (8.75%), and the highest average correlation factor (0.63). © 2014 Alberto Gonzalez-Sanchez et al.

Observations of current velocity, sea surface elevation and vertical profiles of density were obtained in a tropical inlet to determine the effect of a bathymetric depression (hollow) on the tidal flows. Surveys measuring velocity profiles were conducted over a diurnal tidal cycle with mixed spring tides during dry and wet seasons. Depth-averaged tidal velocities during ebb and flood tides behaved according to Bernoulli dynamics, as expected. The dynamic balance of depth-averaged quantities in the along-channel direction was governed by along-channel advection and pressure gradients with baroclinic pressure gradients only being important during the wet season. The vertical structure of the along-channel flow during flood tides exhibited a mid-depth maximum with lateral shear enhanced during the dry season as a result of decreased vertical stratification. During ebb tides, along-channel velocities in the vicinity of the hollow were vertically sheared with a weak return flow at depth due to choking of the flow on the seaward slope of the hollow. The potential energy anomaly, a measure of the amount of energy required to fully mix the water column, showed two peaks in stratification associated with ebb tide and a third peak occurring at the beginning of flood. After the first mid-ebb peak in stratification, ebb flows were constricted on the seaward slope of the hollow resulting in a bottom return flow. The sinking of surface waters and enhanced mixing on the seaward slope of the hollow reduced the potential energy anomaly after maximum ebb. The third peak in stratification during early flood occurred as a result of denser water entering the inlet at mid-depth. This dense water mixed with ambient deep waters increasing the stratification. Lateral shear in the along-channel flow across the hollow allowed trapping of less dense water in the surface layers further increasing stratification. © 2012 Elsevier Ltd.

Background: Depression is highly prevalent in patients with chronic physical illnesses. A promising intervention for this group of patients is the collaborative care treatment as developed in the us. AIM: To demonstrate the prevalence of depression and the risk factors of depression in diabetes patients, to describe how the screening for depression can be carried out and to assess whether the collaborative care treatment in the Netherlands is effective. METHOD: A questionnaire was completed every three months in order to determine whether there was an improvement in patients' depression and physical symptoms.The outcomes were analysed by means of the multilevel logistic regression analyses. RESULTS: On the basis of the Patient Health Questionnaire, about 26% of the diabetes patients were found to have a depression.This questionnaire was validated for the measurement of depression in diabetes patients, the best results being found at a cut-off point of 12. In cases of fairly severe depression, collaborative care had no effect on depressive symptoms but did reduce severe physical complications. In cases of more severe depression, collaborative care only had an effect on depressive symptoms, but was not found to have any effect on physical complications. CONCLUSION: There is evidence that collaborative care can reduce depression and physical complications in chronically ill patients. However, more research is needed to find out whether collaborative care can become more effective if it is supplemented with digital methods and group therapy.

Oban, Scotland, 28-Oct-2016 — /EuropaWire/ — A developing form of aquaculture that sees seaweed and filter-feeding shellfish grown next to traditional fish farms can help deliver greater productivity and reduce environmental impact, say a research group led by SAMS researchers. The European-based researchers involved in the four-year IDREEM project, which ended this month, believe Integrated Multi-trophic Aquaculture (IMTA) could potentially address a number of challenges in the flat-lining European aquaculture industry. Whereas traditional aquaculture/mariculture practice typically sees different types of organisms grown separately, IMTA is a concept where different species are grown together in such a way that the invertebrates and/or plants can recycle the nutrients that are lost from the culture of the other species. “The whole idea of IDREEM was to put the industry at the centre of the project,” said project co-ordinator Dr Adam Hughes (pictured), head of aquaculture at SAMS. “It wasn’t about just research, but rather about mapping and benchmarking industry as it developed different IMTA production systems in Europe. “After four years of hands-on practical experience, the project has achieved a better understanding for aquaculture producers. Research and has shown that, even though the conditions are not yet fully in place in Europe for the wide scale adoption of IMTA, there is a growing commercial interest, consumer demand, and an economic and environment case for the adoption of IMTA, as well as clear policy drivers for its future development.” The work carried out by 15 partners across Europe has gone a long way to develop IMTA into a practical proposition for European aquaculture. Through the life of the project seven different fin-fish producers have IMTA operations in place, and the first IMTA products have been brought to market and sold. However, several barriers still hamper the full commercial uptake of IMTA. Dr Hughes said: “We spent a lot of time trying to understand the regulatory framework for the development of IMTA. There is a policy driver for IMTA in national and European policy but there seems to be a gap between the policy and the regulation. For some countries the process of getting a licence for IMTA can be smooth and for others it can take several years.” Among the findings from the project was a need to develop a market for aquaculture seaweed in Europe, as seaweed is a crucial component of most IMTA systems. For seaweeds to make a significant contribution to nutrient reduction they need to be grown in larger volumes than has been practised to date. The findings from IDREEM are detaileded in the final project publication “Beyond Monoculture – Developing Integrated Multi-trophic Aquaculture in Europe”, which was released on the occasion of the IMTA session at the recent Aquaculture Europe 2016 in Edinburgh. BBC Scotland’s Landward produced a feature on IMTA following a visit with Dr Hughes to the IMTA site on Loch Fyne, Argyll, run by the Scottish Salmon Company, a commercial partner in the IDREEM project. It can be viewed here on BBC iPlayer until November 25. About IDREEM IDREEM (Increasing Industrial Resource Efficiency in European Mariculture) is a European research project launched in 2012 to protect the long-term sustainability of European aquaculture by developing and demonstrating a new innovative production technology, Integrated Multi-Trophic Aquaculture or IMTA. The €5.7 million project is coordinated by the Scottish Association for Marine Science (SAMS) and delivered in collaboration with fourteen industrial and research partners from across Europe. The project has received funding from the European Union’s Seventh Framework Programme for research, technological development and demonstration under grant agreement no. 308571.
