Perfusion dynamics of 16 free DIEP flaps and 4 free SIEA flaps were studied during the first, third, and sixth postoperative day using dynamic infrared thermography (DIRT). For both flap types the zone positioned over the perforator is perfused first, followed by the adjacent ipsilateral zone, and finally the contralateral zones. Perfusion of the subdermal plexus of all zones preceded the perfu...

Mismatch of territories under authority of local governments with urban-regional activity domains, on one hand, has caused numerous problems and, on the other hand, has hindered taking maximum advantage of regional capacities and partial and competitive advantages. Hence, application of a new regionalism approach, which focuses on shared planning and management by all stakeholder groups within ...

We determined the taxonomic composition of the bacterioplankton of the epipelagic zone of the Atlantic Ocean along a latitudinal transect (51°S-47°N) using Illumina sequencing of the V5-V6 region of the 16S rRNA gene and inferred co-occurrence networks. Bacterioplankon community composition was distinct for Longhurstian provinces and water depth. Free-living microbial communities (between 0.22 ...

An analytical one-dimensional model for vertical transmission of barometric pressure in soil unsaturated zone has been developed to examine the effect of free boundary caused by water table. The model is applicable to a special case in which the water table moves in according to the pressure with high barometric efficiency. Ambient sinusoidal pressure fluctuation is assumed at the soil surface....

Abstract A model of the thermal and hydrodynamic structure subduction zone is proposed. This includes free convection flows in asthenospheric layer C (mantle transition zone). Temperature profiles subducting lithospheric plate, as well continental limb zone, are presented. The heat flux due to friction at contact between plate significantly affects transfer and, consequently, temperature field ...

Introduction Livestock diseases in most developing countries are often widely distributed. The wide distribution of diseases often renders whole countries ineligible to participate in international trade of meat and meat products 1. These trade restrictions serve as a continuous primary source of revenue loss. The World Organisation for Animal Health (OIE) now promotes establishment of disease ...

A scattering-free, polarization controllable Fresnel zone plate lens is demonstrated using a photo-induced alignment of the dye-doped liquid crystal film. This photo-aligned liquid crystal zone plate provides orthogonal polarization states for odd and even zones. The different focus orders can be separated because of their different polarization states. The fabrication process is relatively sim...

The present paper deals with a dynamic reaction model of a fishery. The dynamics of a fishery resource system in an aquatic environment consists of two zones: a free fishing zone and a reserve zone. To protect fish population from over exploitation, a control instrument tax is imposed. The existence of its steady states and their stability are studied. The optimal harvest policy is discussed ne...
