Estimating age at maturation and energy-based life-history traits from individual growth trajectories with nonlinear mixed-effects models
Provedor de dados: 5
Autores: Brunel, Thomas; Ernande, Bruno; Mollet, Fabian M.; Rijnsdorp, Adriaan D.
A new method is presented to estimate individuals’ (1) age at maturation, (2) energy acquisition rate, (3) energy expenditure for body maintenance, and (4) reproductive investment, and the multivariate distribution of these traits in a population. The method relies on adjusting a conceptual energy allocation model to individual growth curves using nonlinear mixed-effects modelling. The method’s performance was tested using simulated growth curves for a range of life-history types. Individual age at maturation, energy acquisition rate and the sum of maintenance and reproductive investment rates, and their multivariate distribution, were accurately estimated. For the estimation of maintenance and reproductive investment rates separately, biases were observed...

Integrating the effects of salinity on the physiology of the eastern oyster, Crassostrea virginica, in the northern Gulf of Mexico through a Dynamic Energy Budget model
Provedor de dados: 5
Autores: Lavaud, Romain; La Peyre, Megan K.; Casas, Sandra M.; Bacher, Cedric; La Peyre, Jerome F.
We present a Dynamic Energy Budget (DEB) model for the eastern oyster, Crassostrea virginica, which enables the inclusion of salinity as a third environmental variable, on top of the standard foodr and temperature variables. Salinity changes have various effects on the physiology of oysters, potentially altering filtration and respiration rates, and ultimately impacting growth, reproduction and mortality. We tested different hypotheses as to how to include these effects in a DEB model for C. virginica. Specifically, we tested two potential mechanisms to explain changes in oyster shell growth (cm), tissue dry weight (g) and gonad dry weight (g) when salinity moves away from the ideal range: 1) a negative effect on filtration rate and 2) an additional...

Tubewell transfer in Gujarat:  A study of the GWRDC approach
Provedor de dados: 31
Autores: Mukherji,   Aditi; Kishore,   Avinash.
In India public (government) tubewells were built with the intention of providing irrigation to all categories of farmers in a fair, equitable and affordable manner. However, most public tubewell programs across India have failed on all these counts. Efforts to transfer their management to water users too have met with little success. Nonetheless, the Gujarat Water Resources Development Corporation (GWRDC)-a state-owned public company-has achieved rare success in tubewell transfer by handing over management of around 60 percent of public tubewells in the Gujarat state to user groups. This study tries to identify the factors that helped in accelerating the transfer process and evaluate the performance of transferred tubewells against those owned by...

Charging for irrigation water:  The issues and options, with a case study from Iran
Provedor de dados: 31
Autores: Perry,   Christopher J.
Inadequate funding for maintenance of irrigation works and emerging shortages of water are prevalent. The use of water charges to generate resources for maintenance and to reduce demand is widely advocated. Examples from other utilities, and from the domestic/industrial sectors of water supply suggest the approach could be effective. In developing countries, the facilities required for measured and controlled delivery of irrigation are rarely in place, and would require a massive investment in physical, legal and administrative infrastructure. To be effective in curtailing demand, the marginal price of water must be significant. The price levels required to cover operation and maintenance (O&amp;M) costs are too low to have a substantial impact on demand,...

Stereotyped behaviors in captive primates are often caused by unsuitable conditions. Environmental enrichment has been used to reduce these behaviors, and also to increase the frequency of behaviors appropriate to the species. In this pilot study we evaluated whether behavioral enrichment influences food intake by the black tufted-ear marmoset, Callithrix penicillata (É. Geoffroy Saint-Hilaire, 1812), by calculating energy maintenance requirements. We evaluated 16 individually housed, healthy adult black tufted-ear marmosets, randomly divided into two treatment groups, one with behavioral enrichment and one without. The enrichment techniques included structural aspects, such as placing fixed and mobile objects in the cage and supplying dry foods in an...

Recommendations for hygiene of masks and circuits in mechanically home ventilated patients
Provedor de dados: 55
Autores: Toussaint,Michel; Reychler,Gregory.
Home mechanical ventilation requires equipment, consisting of a generator of pressure, a tubing and an interface to deliver air to the patient. Instructions for equipment maintenance are generally not based on scientific evidence. Studies however have reported that tubing and masks used at home are the most commonly found as very dirty and contaminated. Dirtiness and contamination of equipment potentially expose patients to a higher risk of airway colonization, which, in turn, should cause respiratory infections. For this reason, published hygiene instructions include the use of disinfectant solution. Nevertheless, they generally fail to explain how basic maintenance may be achieved by simple cleaning with soap and water. The instructions for post-cleaning...
