The boundary identification represents an interesting and difficult problem in image processing, mainly if two flat zones are separated by a gradual transition. The most common operators work very well for sharp edges, but fail for gradual transitions. In this work, we have done a characterization for gradient by a study of the opening residues. This characterization is useful to identify and c...

The objective of this paper was to spatially quantify diffuse pollution sources and estimate the potential efficiency of applying riparian buffer zones as a conservation practice for mitigating chemical pollutant losses. This study was conducted using a semi-distributed Soil and Water Assessment Tool (SWAT) model that underwent extensive calibration and validation in the Sulejów Reservoir catch...

Abstract We evaluated how three widths of buffer zones on greater than or equal to 100-ha wetlands (240, 300, and 390 m) rivers (10, 20, 30 would help meet watershed conservation goals in the Upper Peninsula Michigan, USA, whether doing so also protect each predominant types terrestrial natural communities across landscape. The use (even narrowest assessed) around riparian met exceeded targets ...

Pesticide-Application-Manager (PAM) is an internet-based Decision Support System (DSS) which automates important processes in crop protection by using up-to-date ICTtechnologies and integrating data from different public and private sources. PAM focuses in particular on supporting farmers complying with legal buffer zones to water bodies, settlements and other terrestrial elements deserving pro...

thirty-five fungal strains which isolated from vegetable wastes, were screened for the use of polygalacturonic acid as the sole carbon source. twenty-five isolates were positive for polygalacturonase activity in cup-plate assay, as evidenced by clear hydrolysation zones. the most productive strain was determined by measuring clear zones formed around colonies stained with ruthenium red. the hig...

In this work we present an efficient strategy to deal with plasma physics simulations in which localized departures from thermodynamical equilibrium are present. The method relies on the introduction of buffer zones which realize a smooth transition between the kinetic and the fluid regions. In this paper we extend the idea, recently developed in [13, 14], of dynamic coupling and of buffer zone...

Rho GTPases control many cytoskeleton-dependent processes, but how they regulate spatially distinct features of cytoskeletal function within a single cell is poorly understood. Here, we studied active RhoA and Cdc42 in wounded Xenopus oocytes, which assemble and close a dynamic ring of actin filaments (F-actin) and myosin-2 around wound sites. RhoA and Cdc42 are rapidly activated around wound s...

To evaluate the effects of distal design of a proximally coated femoral component on periprosthetic bone remodeling, we prospectively performed 21 one-stage bilateral total hip arthroplasties using a distally tapered and a distally cylindrical stem with the same proximal design, randomized to side. All hips showed good outcomes clinically and radiographically at the final follow-up, average of ...
