Background and Aim: Minimizing the polymerization shrinkage of composite resins is a critical goals in composite restorations. Many factors affect polymerization shrinkage. This study aimed to evaluate the effect of composite resin shade on polymerization shrinkage. Materials and Methods: In this in vitro study, 14 composite discs measuring 1.5×8 mm were fabricated. The samples were prepared u...

In the context of ridge regression, the estimation of ridge (shrinkage) parameter plays an important role in analyzing data. Many efforts have been put to develop skills and methods of computing shrinkage estimators for different full-parametric ridge regression approaches, using eigenvalues. However, the estimation of shrinkage parameter is neglected for semiparametric regression models. The m...

A coupled phase field and crystal plasticity model is established to analyze formation of dislocation structures residual stresses during rapid solidification additively manufactured 316L stainless steel. The work focuses on investigating the role microsegregation related intra-grain cellular microstructure 316L. Effect shrinkage considered along with mediated plastic flow material solidificati...

objective: potato is the fourth important food crop after wheat, rice and maize. shrinkage  of  food  materials  has  a negative  consequence  on  the  quality  of  the dehydrated product. the main objective pursued in this paper is to investigate the shrinkage amount of potato slices during drying process using vacuum-infrared method. methods: in this work, the effect of the infrared radiation...

The structure of dendritic spines is highly plastic and can be modified by neuronal activity. In addition, there is evidence that spine head size correlates with the synaptic α-amino-3-hydroxy-5-methylisoxazole propionic acid (AMPA) receptor (AMPAR) content, which suggests that they may be coregulated. Although there is evidence that there are overlapping mechanisms for structural and functiona...

RC structures get damaged over time due to several phenomenons such as shrinkage, thermal deformations, creep and corrosion. This damage starts at early age continues during the lifetime of structures. In order account for effects on seismic response structures, a research project combining both an experimental numerical part was conducted. part, two types portal frames that evolved either in e...

In conventional concrete, micro-cracks develop before structure is loaded because of drying shrinkage and other causes of volume change. When the structure is loaded, the micro cracks open up and propagate because of development of such micro-cracks, results in inelastic deformation in concrete. Fibre reinforced concrete (FRC) is cementing concrete reinforced mixture with more or less randomly ...
