In this study, we designed a structural model to determine the relationships among push–pull factors, institutional situations, and satisfaction during COVID-19 pandemic. The 17 selected indicators fell under five domains, namely push pull leadership, international strategies, satisfaction. Structural equation modeling (SEM) was used verify assumptions of model. Based on 1005 degree-seeking stu...

Abstract: A modified large thrust ultrasonic linear motor using a T-shape configuration composed of two orthogonal sandwich-type transducers has been proposed in this paper. It is an improved version of a previous T-shape motor. The vertical transducer is used to generate the normal force between the driving foot and slider, while the other push-pull–type horizontal transducer is applied to gen...

Acceptance of the klap speed skate was fully realized on the world speed skating scene in 1997. However, one of the most important unknowns regarding the klapskate was the positioning of the point of foot rotation (pivot point), which is believed to play an important role in optimizing klapskate performance. The purposes of this study were to explore the ankle, knee, and hip joint mechanical ch...

Objective: The aim was to develop osmotic tablets of nateglinide by two methods namely elementary pump (EOP) and push-pull (PPOP) method for controlled drug release.
 Methods: were prepared the wet granulation evaluated various physicochemical parameters, in-vitro dissolution dissolution. optimised formulation obtained in both further characterised FTIR, stability studies pharmacokinetic s...

background and aims. various factors influence the interfacial bond between the fiber posts and root canal dentin. the aim of the present study was to evaluate the effect of pre-warming of resin cement on the push-out bond strength of fiber posts to various segments of root canal dentin. materials and methods. in this in vitro study, 40 single-rooted human premolars were decoronated and underwe...

this in-vitro study sought to assess the push-out bond strength of a total etch and 2 self-etch bonding systems to intracanal dentin of primary anterior teeth (pat).thirty-six primary anterior teeth were randomly divided into 3 groups of 5(th) generation (single bond 2), 6(th) generation (clearfil se) and 7(th) generation (single bond universal) bonding agents. the canal orifice was restored wi...

Background and aims. The single-cone technique has gained some popularity in some European countries. The aim of the present study was to compare the push-out bond strength of gutta-percha to root canal dentin with the single-cone and cold lateral compaction canal obturation techniques. Materials and methods . The root canals of 58 human mandibular premolars were prepared using modified crown-d...

— In this paper we consider smooth extensions of cohomology theories. In particular we construct an analytic multiplicative model of smooth K-theory. We further introduce the notion of a smooth K-orientation of a proper submersion p : W → B and define the associated push-forward p̂! : K̂(W ) → K̂(B). We show that the push-forward has the expected properties as functoriality, compatibility with pul...
