Radiative heterogeneity in greenhouses significantly influences crop activity, particularly transpiration and photosynthesis. This is especially true for plastic tunnels, which are the most commonly used greenhouse type in the Mediterranean basin. A computer model was generated for this study based on sun movement, greenhouse geometry, transmittance of the cover and weather conditions. Experime...

Properly injected local anesthesia can be almost painless with attention to a few simple details that have been published in a previous Plastic and Reconstructive Surgery video1 (see Video 3, which demonstrates injection tips for “hole in one” local anesthesia, available in the Related Videos section of “The Safe Management of Anesthesia, Sedation, and Pain in Plastic Surgery” CME article in th...

Displacements around a tunnel, occurring as a result of excavation, consist of the elastic and plastic parts. In this paper, we discuss the elastic part of displacements as a result of excavation, called net displacement. In general, the previous analytical solutions presented for determining the displacements around a circular tunnel in an elastic medium do not give the net displacements...

Demand for and availability of blueberries has increased substantially over recent years, driven in part by their health-promoting properties. Three blueberry varieties ('Rocío', V2, and V3) were grown under two cultivation systems (open-field and plastic tunnels) and subjected to two irrigations regimes (100% and 80% of crop evapotranspiration) in two consecutive years (2011-2012). They were e...

The aim of this study was to evaluate the effects of different covers (oil, plastic film, perforated polystyrene float, peat and zeolites) on slurry settling characteristics and ammonia emission during storage and following surface application in the field. Laboratory trials were carried out for 15 days using a pilot scale device. Samples of 5 kg slurry were used. At the end of the storage peri...

OBJECTIVE To describe an ultrasonography-guided technique for cubital tunnel injection. METHOD The ulnar nerves from 12 elbows of 6 adult cadavers were scanned, and the cross-sectional areas of the ulnar nerves, cubital tunnel inlets and outlets were measured by using ultrasonography. All elbows were dissected after an ultrasonography-guided dye injection at the inlet of the cubital tunnel. T...

A closed-form analytical solution to rheological phenomena is obtained based on Hoek-Brown (HB) yield criterion and the generalized Bingham model. Once circular tunnel excavated, an initial plastic region formed. When total stresses fulfil condition, steps into viscoplastic region, in which displacement develops with time. The one-dimensional constitutive equation of model transformed a three-d...
