Land reforms in developing countries provide a good experiment for study on development economics, and in the case Taiwan the land reform provides specific historical context for us to closely examine the relationship between redistribution and growth. In this paper, we use panel data on the fifteen counties of Taiwan around 1950s and 1960s to empirically evaluate whether redistributive land re...

As several cases of the disease caiiea unionypne varieri, ur r uugus Foot, have occurred under my observation and treatment in the Government Charitable Dispensary, Hissar, I subjoin the notes of a case, -which, I hope, will be interesting:? Mota, aged 45, cultivator of Faidalpore, in the Sekur Principality, was admitted into the Hissar Charitable Dispensary on the 10th of June 1876, with enorm...

PURPOSE The present study investigates sinus membrane rupture in direct maxillary sinus lift with the rotary technique and with ultrasound, examining the survival of implants placed after sinus augmentation, and analyzing the bone gain obtained after the operation and 12 months after placement of the prosthetic restoration. MATERIALS AND METHODS A retrospective study was made of 45 patients r...

The aim of this study was to evaluate the effect of RaCe, FlexMaster and ProFile rotary instruments on smear layer formation by scanning electron microscopy. Eighty-four caries-free freshly extracted human single-rooted teeth were selected and divided into three groups, each containing 28 teeth. The teeth were instrumented with rotary instruments sequentially: Group A: ProFile Rotary Instrument...

Aim The aim of this study is to compare curved root canal preparation between reciprocal rotary files and rotational rotary files in extracted teeth using cone-beam computed tomography (CBCT). The independent variable was the file type (reciprocal vs. rotary), and the primary outcome variable was the centering ratio of distance change after canal preparation. Secondary outcomes were canal trans...

DNA has been used to construct a wide variety of nanoscale molecular devices. Inspiration for such synthetic molecular machines is frequently drawn from protein motors, which are naturally occurring and ubiquitous. However, despite the fact that rotary motors such as ATP synthase and the bacterial flagellar motor play extremely important roles in nature, very few rotary devices have been constr...

Four-month-old infants were allowed to manipulate, without vision, two rings attached to a bar that permitted each ring to undergo rotary motion against a fixed surface. In different conditions, the relative motions of the rings were rigid, independent, or opposite, and they circled either the same fixed point outside the zone of manipulation or spatially separated points. Infants' perception o...

ultrasonic machining (usm) is a mechanical material removal process used to erode holes and cavities in hard or brittle work pieces by using shaped tools, high-frequency and an abrasive slurry. this paper addresses the concept and development of an expert system (es) for hard and brittle material, such as glass, quartz, diamond, carbides, semi conducting materials, ceramic and graphite which ca...
