In the recent past, Pulsating Heat Pipes (PHPs) have attracted the attention of many researchers as viable candidates for enhanced heat transfer through passive two-phase heat transfer mechanism. Although a complete theoretical understanding of operational characteristics of this device is not yet achieved, there are many emerging niche applications, ranging from electronics thermal management ...

We present a new method of treatment for nasal valve dysfunction caused by insufficiency or stenosis in a patient who refused open septum revision despite a significant degree of septum deviation. The Anterior Spreader Flap (ASF) technique was suggested as an alternative to open nasal septum revision and was performed under local anesthesia. Computational fluid dynamics (CFD) tests were perform...

BACKGROUND Despite the importance of soft tissue balancing during total knee arthroplasty (TKA), all estimating techniques are dependent on a surgeon's manual distraction force or subjective feeling based on experience. We developed a new device for dynamic gap balancing, which can offer constant load to the gap between the femur and tibia, using pneumatic pressure during range of motion. MET...

A simulated curved root canal in a resin block was enlarged to size 40 and used to compare the depth of accessory cone penetration and weight of obturation occurring with the use of different obturation techniques and spreader-accessory cone combinations. Twelve groups, each consisting of 10 obturations, were created. A conventional lateral condensation technique was used in six groups and a me...

BACKGROUND Handling of upper lateral cartilages (ULCs) is of prime importance in rhinoplasty. This study presents the experiences among 2500 cases of rhinoplasty in the past 10 years for managing of ULCs to minimize unwilling results of the shape and functional problems of the nose. METHODS All cases of rhinoplasties were done by the same surgeon from 2002 to 2013. Management of ULCs changed ...

Identifying a set of influential spreaders in complex networks plays a crucial role in effective information spreading. A simple strategy is to choose top-r ranked nodes as spreaders according to influence ranking method such as PageRank, ClusterRank and k-shell decomposition. Besides, some heuristic methods such as hill-climbing, SPIN, degree discount and independent set based are also propose...

PREMISE OF THE STUDY Positional cloning in combination with phenotyping is a general approach to identify disease-resistance gene candidates in plants; however, it requires several time-consuming steps including population or fine mapping. Therefore, in the present study, we suggest a new combined strategy to improve the identification of disease-resistance gene candidates. METHODS AND RESULT...

Rumor is a kind of social remark, that is untrue, and not be confirmed, and spreads on a large scale in a short time. Usually, it can induce a cloud of pressure, anxiety, and panic. Traditionally, it is propagated by word of mouth. Nowadays, with the emergence of the internet, rumors can be spread by instant messengers, emails, or publishing. With this new pattern of spreading, an ISRW dynamica...

To successfully implement a packaging concept, it is imperative to resolve many challenging issues related to materials and processing, which will result in improved thermal management of the power electronics modules. Almost every parameter of a power device is a function of temperature. The heat generated by these active devices, which reduces circuit efficiency, may also degrade circuit perf...

Spreader beams used in lifting operations undergo a purely compressive load to spread apart the ends of sling which enables large payloads be lifted from single point, such as crane hook, without damage. A modular spreader beam can made using subcomponents different standard sizes create any length, making them more versatile and cost-effective than non-modular beams. However, while manual calc...
