  Background: Stainless steel instruments have long used as conventional instruments applied in root canal therapy procedures. Being difficult the canal preparation by these instruments, a new generation of nickel-titanium instruments have introduced. The aim of this study was to compare the manual Ni-Ti instruments with the Flex Master® Ni-Ti rotary system in canal preparation.   Materials & M...

Stomata are formed by a pair of guard cells which have thickened, elastic cell walls to withstand the large increases in turgor pressure that have to be generated to open the pore that they surround. We have characterized FOCL1, a guard cell-expressed, secreted protein with homology to Hyp-rich cell wall proteins. FOCL1-GFP localizes to the guard cell outer cuticular ledge and plants lacking FO...

By the virtue of the nature of the vapor-liquid-solid (VLS) growth process in semiconductor nanowires (NWs) and their small size, the nucleation, propagation, and termination of stacking defects in NWs are dramatically different from that in thin films. We demonstrate germanium-silicon axial NW heterostructure growth by the VLS method with 100% composition modulation and use these structures as...

Most surgeons seem to favour the former method. Even when the erisophake is used instead of forceps, the technique of zonulolotomy and delivery of the lens remains essentially the same. Since the introduction of A.C.T., however, mechanical zonulolotomy has been replaced by enzymatic zonulolysis and the extraction of the lens by seizing it at the 12 o'clock position is being increasingly practis...

Abstract. Field experiences are a critical component of undergraduate geoscience education; however, traditional onsite field not always practical due to accessibility, and the popularity alternative modes learning in higher education is increasing. One way support student access through virtual trips, implemented either independently or conjunction with in-person trips. We created trip (VFT) G...
