This thesis is based on a large prospective, observational study on the various factors affecting the success of endoscopic dacryocystorhinostomy (endo DCR). There are 3 components to this study. Canalicular closure has long been thought to be a major cause for early failure and the reason behind routine silicone intubation. The first component investigated the incidence of canalicular closure ...

Background and Aim: Tissue adhesives can be used as an alternative to conventional sutures in periodontal surgery. The free gingival graft (FGG) is a technique used to increase the zone of keratinized gingiva. The shrinkage of FGGs is a well-known clinical phenomenon. However, to our knowledge, there is no data available regarding the dimensional changes in FGG procedure using non-suturing tech...

Early age cracking in concrete is caused by a combination of the chemical and autogenous shrinkage exhaustion water pores during hydration cement phases. Generally, this process takes place first 72 h casting. The use supplementary cementitious materials (SCMs) can mitigate due to several factors, among them: dilution effect, provision extra nucleation sites high specific surface SCMs, increase...

A current model posits that cofilin-dependent actin severing negatively impacts dendritic spine volume. Studies suggested that increased cofilin activity underlies activity-dependent spine shrinkage, and that reduced cofilin activity induces activity-dependent spine growth. We suggest instead that both types of structural plasticity correlate with decreased cofilin activity. However, the mechan...

BACKGROUND AND PURPOSE The human brain exhibits a complex pattern of differential aging. The purpose of this study was to examine whether age differences in the volume of cerebellar regions and the ventral pons are differential or generalized, whether the age-related shrinkage is linear or exponential, and whether there are sex differences in the size of the cerebellum and pons. METHODS The v...

Capillary pressure is frequently measured to evaluate the shrinkage performance of concrete but has been limited pressures <100 kPa preventing a better understanding early age factors affecting durability. In this study, high capacity tensiometers (HCTs) were employed for first time investigate behavior concrete. The evolution capillary in Self-Consolidating Concrete (SCC) with and without redu...

This study aims at investigating the early-age behaviour of textile-reinforced cementitious matrix composites. Six different configurations with two types reinforcements (glass and carbon meshes) three reinforcement layers were tested. Experimental measurements conducted using various measurement techniques: optical fibre sensors, thermocouples, thermal cameras, Fourier transform infrared spect...

Significant drying shrinkage is one of the main limitations for the wider utilization of alkali-activated slag (AAS). Few previous works revealed that it is possible to reduce AAS drying shrinkage by the use of shrinkage-reducing admixtures (SRAs). However, these studies were mainly focused on SRA based on polypropylene glycol, while as it is shown in this paper, the behavior of SRA based on 2-...
