the aim of ideal canal preparation is to prevent iatrogenic aberrations such as transportation. the aim of this study was to evaluate the root canal transportation by reciproc file with and without glide path.thirty acrylic-resin blocks with a curvature of 60° and size#10 (2% taper) were assigned into two groups (n= 15). in group 1, the glide path was performed using stainless steel k-files siz...

In a Massively Multiplayer Online (MMO) game, the packet data between the server and the client must be minimized. Spatial partitioning and field of view processing are indispensable to reduce the packet data. This paper analyzes the size of the spatial partition and the range of the field of view. Experiments were conducted on the optimal size of the spatial partition and field of view in the ...

An analogue of McEliece’s cryptosystem, the Gabidulin-Paramonov-Trejtakov (GPT) public-key cryptosystem is based on rank-metric-based Gabidulin codes instead of Goppa codes. The GPT cryptosystem has attracted steady attention since it is much more robust against the decoding attacks and can therefore achieve the same level of security with much smaller keys. The key sizes, nonetheless, may stil...

The purpose of this study was to investigate the effects of size and type of incorporated model molecules on the polymer degradation and release profile from thermosensitive triblock copolymer based controlled delivery systems. In vitro release of the incorporated molecules demonstrated slow release for risperidone (molecular weight (Mw) = 410.48 Da; partition coefficient (Ko/w) = 3.49), while ...

GPT public key cryptosystem was proposed by Gabidulin, Paramonov and Tretjakov in 1991. This cryptosystem is based on rank error correcting codes. The main advantage of using rank codes in cryptography is that, it has smaller key size as compared to other code based public key cryptosystems. Several attacks against this system were published and some modifications were also proposed withstandin...

Tillage practices can influence the pore size distribution (PSD) of soil, affecting soil physical and hydraulic properties as well processes that are essential for plant growth, hydrology, environmental studies modeling. A study was conducted to assess effect no-tillage (NT) conventional tillage (CT) on PSD derived from soil–water retention curves (SWRCs) using van Genuchten’s equation (vG) at ...
