OBJECTIVES With an increasing number of studies highlighting regional social capital (SC) as a determinant of health, many studies are using multi-level analysis with merged and averaged scores of community residents' survey responses calculated from community SC data. Sufficient examination is required to validate if the merged and averaged data can represent the community. Therefore, this stu...

In this study, curved maxillary molar root canals were instrumented with RaCe rotary system to evaluate: 1. the occurrence of canal transportation using a radiographic platform; 2. the action of the instruments on the dentin walls, centering ability and canal enlargement by analysis of digital images; and the percentage of regular dentin surfaces and debris within the canal by histological anal...

In the last two decades many researchers focused on development of innovative building structures with aim achieving seismic resilience. Among others, steel Moment Resisting Frames (MRFs) equipped friction devices in beam-to-column joints have emerged as an effective solution able to dissipate input energy while also ensuring damage-free behaviour system. However, date, little attention has bee...

Scopul sintezei cinematice a mecanismelor este determinarea dimensiunilor elementelor componente, în condiţiile impuse prin mişcările unor puncte sau elemente. Rezolvarea unei astfel de probleme se reduce la rezolvarea unui sistem de ecuaţii neliniare. Ca urnare, problemele de sinteză cinematică nu au soluţii unice. Pentru oprimizarea dimensiunilor unui mecanism de prehensiune, funcţia obiectiv...

We investigated the most effective rocking motion for inducing sleep in adults. We prepared ten types of rocking motions, including two types of mother’s rocking motions. The sleep-inducing effect of all the rocking motions was evaluated using Thurstone’s paired comparison method (Case V). From statistical analysis of the subjective experimental results we found that, of the ten types of rockin...

INTRODUCTION Cleaning and shaping without making procedural errors have always been a challenge in endodontics, particularly when the root canals are curved. Several rotary instruments have been developed to minimize such errors. The purpose of this study was to compare the shaping ability of 2 rotary file systems, BioRace (BR; FKG, La Chaux-de-Fonds, Switzerland) and ProTaper Next (PTN; Dentsp...

This paper presents a rational procedure to optimize design for mass timber rocking wall systems utilizing genetic algorithm (GA) beyond typical displacement-based metrics wood buildings. Traditional is limited simple displacement targets, with optimization techniques (GA), it feasibly consider more performance chrematistics (e.g. costs, serviceability, etc.). By formulating drift targets and o...

Rocking isolation of structures is evolving as an alternative design concept in earthquake engineering. The present paper investigates the seismic performance of an actual overpass bridge of the Attiki Odos motorway (Athens, Greece), employing two different concepts of rocking isolation: (a) rocking of the piers on the foundation (rocking piers); and (b) rocking of the pier and foundation assem...

Sep 26 Alex Mogilner, UC Davis Self-organizing microtubule asters in mitosis Mitosis is the process of segregation of chromosomes before cell division. This phenomenon is based on self-assembling molecular machine called mitotic spindle. The spindle consists of two asters made of microtubules, dynamic polymers that grow and shrink rapidly and repeatedly probing space and searching for the chrom...
