Container stacking strength is an important performance requirement of corrugated fiberboard. The objective of this study is to examine theoretically how fluting geometry affects fiberboard strength and stiffness under standard relative humidity (RH) and high RH conditions. The fluted medium in a corrugated fiberboard is modeled as a connection of curved arc and straight flank segments passing ...

OBJECTIVE To investigate the effect of bracket-ligature combination on the amount of orthodontic space closure over three months. DESIGN Randomized clinical trial with three parallel groups. SETTING A hospital orthodontic department (Chesterfield Royal Hospital, UK). PARTICIPANTS Forty-five patients requiring upper first premolar extractions. METHODS Informed consent was obtained and pa...

Loops which are linkers connecting G-strands and supporting the G-tetrad core in G-quadruplex are important for biological roles of G-quadruplexes. TTA loop is a common sequence which mainly resides in human telomeric DNA (hTel) G-quadruplex. A series of molecular dynamics (MD) simulations were carried out to investigate the structural dynamics of TTA loops. We found that (1) the TA base pair f...

A 12-year-old female patient presented with proclined upper anteriors on a class II skeletal base, a retrognathic mandible and high maxillary- mandibular plane angle. Lower first molars were mesially tipped and lower second premolars were impacted. Treatment plan included uprighting and distalising the lower molars followed by growth modulation with Jasper Jumper to correct the mandibular retro...

The present case report describes the treatment of a 12-year-old boy who had skeletal Class III malocclusion with concave facial profile, hypodivergent facial pattern with anterior cross bite and deep overbite. The treatment plan included rapid palatal expansion with maxillary protraction and fixed edgewise appliance. The results show that anterior cross bite was corrected and facial esthetics ...

introduction: the aim of this study was to assess the galvanic behavior of different bracket and archwire combinations that are commonly used in orthodontic treatments. methods: three types of orthodontic archwires with a diameter of 0.016×0.022 inch and 80 standard edgewise maxillary central incisor brackets were selected. three groups consisted of different wire-bracket couples and one group ...

Fabrication and use of Cross Laminated Timber (CLT) using tropical woods is still limited at present. Therefore objective the present study aims to determine possibility CLT panels 3 5 layers, fabricated with Tectona grandis Gmelina arborea wood adhesive isocyanate polymer emulsion system catalyzed polymeric isocyanate. Delamination, water absorption, density, flexure test, compression glue-lin...
