identifying the change trends in forms of land surface is one of the main topics in geomorphic system. in this view, we try to assess the stability level of geo systems, boundary changes, instability and prediction of surface forms and processes response. this paper tries to conduct a comparative analysis on the geomorphic equilibrium paradigms, critical thresholds, environmental and natural ha...

Smart Grid is the trend of next generation electrical power system which makes the power grid intelligent and energy efficient. It requires high level of network reliability to support the two-way communication among electrical services, electrical units such as smart meters, and applications. The wireless mesh network infrastructure can provide redundant routes for the Smart Grid communication...

this paper introduces a new method for accelerating current sluggish fem and improving memory demand in fem problems with high node resolution or bulky structures. like most of the numerical methods, fem results to a matrix equation which normally has huge dimension. breaking the main matrix equation into several smaller size matrices, the solving procedure can be accelerated. for implementing ...

BACKGROUND/AIMS Primary repair of a large hiatal hernia is associated with a published recurrence rate of up to 10%; anecdotal rates even higher than this have been reported to the authors. The use of prosthetic material in the repair of other abdominal wall defects has often produced better results than primary repair. We wanted to compare laparoscopic primary repair of large hiatus hernias wi...

Abstract Aim EHS consensus recommends mesh implantation for all incisional hernia (IH) repairs, regardless of size. We propose considering abdominoplasty in the algorithm IH repairs wherein plicated fascia functions as a permanent autologous biologic onlay repair over primary IH. Materials & Methods Four patients with midline IHs underwent abdominoplasty. Their were first closed primarily #...

in this study gill-net selectivity for alburnus chalcoides inhabiting the almus dam lake was estimated. experimental gill-net fishing was conducted using gill-net with 15 mm and 20 mm mesh-size, during october 2002 and september 2003. a total of 254 and 198 specimens of a. chalcoides were caught by gill-net with 15 mm and 198 with the 20 mm mesh-size, respectively. the total length of the fish ...

it is difficult to develop an algorithm which is able to generate the appropriate mesh around the interfaces in bimaterials. in this study, a corresponding algorithm is proposed for this class of unified structures made from different materials with arbitrary shapes. the non-uniform mesh is generated adaptively based on advancing front technique available in abaqus software. implementing severa...

purpose: to report the results of a wrapping technique for hydroxyapatite orbital implants by using mersilen mesh. methods: this study is prospective interventional case series conducted on records of 55 consecutive patients who received a mersilen mesh-wrapped ha orbital implant after enucleation or as a secondary procedure. we recorded results and potiential problem before and after pegging d...

background: teat lacerations are serious injuries thatendanger the survival of a cow within the herd. in excessivelacerations, the wound should be left to heal by second intentionhealing process. however, tissue contraction during healing canchange the alignment of the teat, creating problems for machinemilking. objectives: the purpose of the present study was toevaluate the transplantation of ...
