Tapis kelapa (Coconut filter) as natural fiber, in this time its resources very copius but no longer be exploited and thrown off hand INOA as waste though in fact its used for other material dissimilar inovatif and high economic valuable that is as one of natural fiber alternative to be composite.The objective of this research is to investigate the

The impact on curved box-girder bridges due to vehicle moving across rough bridge deck have been analyzed using bridge-vehicle coupled dynamics.The bridge deck unevenness has been assumed to be a homogeneous random process in space specified by a PSD function.The analysis incorporates the effect of centrifugal forces due to vehicle moving on curved

A carbon-supersaturated (CS-) high-speed steel punch was prepared using low-temperature plasma carburizing for fine blanking of pure titanium plates.The bare high-speed steel punch was also prepared as a reference to describe the adhesion and abrasive galling in the fine blanking of the titanium plates, even in a single shot.The CS-punch was free f

The Solid-State direct current (DC) circuit breaker (SSCB) is a key equipment to ensure the safe and reliable operation of medium-voltage DC (MVDC) distribution networks.A distribution network solid-state DC circuit breaker with current-limiting function (CLSSCB) topology is proposed in this paper.The CLSSCB adds current-limiting circuit and Boxers

The small intestine is third in frequency intraperitoneal organ injured after blunt trauma of abdomen.Peritonitis caused by isolated jejunum perforation is very rare.As most of these cases are accompanied with injuries with other structures in the abdomen, hence it is not suspected.Therefore failure in diagnosis and delay in treating these injuries
