a new design for replacing a missing anterior tooth is described. in this article, a lingually fixed partial denture, its advantages, disadvantages, indication and contraindications have been explained. the ability of this design to replace a single missing central or lateral incisor is discussed.

It is known that short-span high-speed railway viaducts are prone to suffer significant dynamic effects due the passage of moving train loads. Recent technological advances in engineering have resulted track typologies different from conventional ballasted consisting discrete sleepers fastened rails and resting on a ballast bed. In particular, ballastless has been identified as an effective sol...

The aging of reinforced concrete structures is one the biggest concerns in civil engineering today since billions dollars are spent annually on deck repairs and replacements. This study focuses rehabilitation box girders used bridge construction. Bridge with a new overlay possesses many challenges that involve cracking debonding caused by restraining effect substrate. leads to development tensi...

Crack surveys of bridge decks, performed over a 10-year period in northeast Kansas as part of three studies, provide strong guidance in identifying the parameters that control cracking in these structures. The surveys involve steel girder bridges—bridges that are generally agreed to exhibit the greatest amount of cracking in the concrete decks. The surveys include monolithic decks and decks wit...

Distributed supervisory control is a method to synthesize local controllers in discrete-eventsystems with a systematic observation of the plant. Some works were reported on extending this methodby which local controllers are constructed so that observation properties are preserved from monolithic todistributed supervisory control, in an up-down approach. In this paper, we find circumstances in ...

‎given a finite non-cyclic group $g$‎, ‎call $sigma(g)$ the smallest number of proper subgroups of $g$ needed to cover $g$‎. ‎lucchini and detomi conjectured that if a nonabelian group $g$ is such that $sigma(g) < sigma(g/n)$ for every non-trivial normal subgroup $n$ of $g$ then $g$ is textit{monolithic}‎, ‎meaning that it admits a unique minimal normal subgroup‎. ‎in this paper we show how thi...

The need for a high-frequency and high-efficiency gallium nitride (GaN)-based buck converter that can be controlled directly by low swing pulse width-modulated (PWM) signal, without the additional buffers or preamplifiers, poses significant challenge in field of power conversion dynamically supply applications. To solve this problem, letter presents monolithic two-phase synchronous converter, f...

We present a novel switched full-duplex LAN architecture which can greatly simplify the cabling requirements in areas that must support high port densities and/or are subject to frequent changes. Instead of providing a separate cable to connect each host to a dedicated port on a monolithic switch behind the wall, we emulate the shared bus topology from the early days of Ethernet by daisy-chaini...
