Costos Estimados en el 2010 para Establecer y Producir Pitaya (Fruta Dragón) en el Sur de Florida
No full textComo consecuencia de la creciente competencia extranjera y la disminución de rendimientos de los productos agrícolas tradicionales, muchos productores en el Sur de la Florida se han embarcado en una búsqueda agresiva de productos agrícolas que sean alternativas viables. Un producto que ha llamado la atención es la pitaya, una especie de cactus trepador autóctona de las regiones de bosques tropicales de México, Centroamérica y América del Sur. De menos de 50 hectáreas plantadas en la Florida en fecha tan reciente como 2006, la producción se ha multiplicado por seis y ahora se estima en alrededor de 320 acres.

A Fourier-series-based virtual fields method for the identification of three-dimensional stiffness distributions and its application to incompressible materials
No full textWe present an inverse method to identify the spatially-varying stiffness distributions in three-dimensions (3-D). The method is an extension of the classical Virtual Fields Method (VFM) – a numerical technique which exploits information from full-field deformation measurements to deduce unknown material properties – in the spatial frequency domain, which we name the Fourier-series-based Virtual Fields Method (F-VFM). Three-dimensional stiffness distributions, parameterised by a Fourier series expansion, are recovered after a single matrix inversion. A numerically efficient version of the technique is developed, based on the Fast Fourier Transform. The proposed F-VFM is also adapted to deal with the challenging situation of limited or even non-existent knowledge of boundary conditions. The 3-D F-VFM is validated with both numerical and experimental data. The latter came from a phase contrast MRI experiment containing material with Poisson’s ratio close to 0.5; such a case requires a slightly different interpretation of the F-VFM equations, to enable the application of the technique to incompressible materials
Bivalve Mollusks as Hosts in the Fossil Record
No full textParasites are ubiquitous in modern ecosystems, occupy one of the most
successful life modes, promote ecosystem stability, and, despite their typically
diminutive size and lack of a mineralized skeleton, are commonly identifed in the
fossil record. Bivalve mollusks have occupied marine aquatic environments since
the Cambrian, comprise an excellent fossil record, and often preserve traces of
interactions with their parasites. Here we review parasite-host interactions of living
bivalves and the record of parasitism of bivalves that reaches as far back as the
Silurian. Escalation in parasite-host bivalve interactions seems to have occurred in
both the middle Paleozoic and the late Mesozoic to Cenozoic, similar to trends
documented in other antagonistic interactions
Investigating the relationship between age of onset of depressive disorder and cognitive function
No full textObjectives: depressive disorder is commonly associated with impaired cognitive function; however, it is unclear whether the age of onset of the first episode of depression, current depression severity, or historical severity of depressive episodes are associated with cognitive performance.Methods: this study examined baseline cross-sectional data from the ongoing online PROTECT study. A total of 7344 participants, 50 years or older, with a history of depression and no diagnosis of dementia were divided into three groups according to age of onset of their first depressive episode: early-onset, midlife-onset, and late-onset. Performance on measures of visuospatial episodic memory, executive function, verbal working, and visual working memory were evaluated. Demographic and clinical characteristics such as age, education, and severity of symptoms during their worst previous depressive episode and current depression severity were included in multivariate regression models.Results: the late-onset depression group scored significantly lower on the verbal reasoning task than the early-onset group while there were no significant differences found on the other tasks. Midlife-onset depression participants performed better in the visual episodic memory task, but worse on the verbal reasoning task, than early-onset depression participants. Current depression severity was negatively correlated with all four cognitive domains, while historical severity score was found to be significantly associated with cognitive performance on the verbal reasoning and spatial working memory tasks.Conclusions: the most important indicator of cognitive performance in depression appears to be current, rather than historic depression severity; however, late-onset depression may be associated with more executive impairment than an early-onset depression
Measuring displacement field detection of unbounded regions in a single lap Joint with moiré
No full textThe goal of this work is the development of an experimental technique to measure the displacement field and to perform detection of unbonded regions [1] in a single lap joint [2, 3]. The proposed experimental technique is based on the use of Moiré Interferometry. It is a field technique that allows in-plane displacement measurements without contact and with high resolution [4, 5]. Grating replication techniques were developed to record high quality diffraction gratings onto the specimen’s surfaces [6]. It was also, developed an optical assembly of laser interferometry used to generate the master grating (virtual) [7]. A tension load was applied to a lap joint and its deformation was accessed by the interference between the reference grating, recorded on the object surface, and virtual master grating generated by laser interferometry. A phase shifting technique [8] was developed to allow the phase map calculation. Image processing techniques [9] will be used to assess the in-plane displacement field.
A finite elements code (ANSYS®) will be used to calculate the displacement field [10, 11]. An unbonded region in a single lap joint was numerically simulated and the obtained results will be compared with those obtained in the experimental work. In the figure 1 it’s possible to observe the displacement field, measured in a horizontal direction, of a single lap sound joint: and the results obtained by numerical simulation
