Adhesion testing of aircraft tires

Adhesion testing appeared to offer a less burdensome alternative to replace some of the dynamometer tests. Accordingly, test results and data were requested from retreaders who had used adhesion testing

Implementasi Model Pembelajaran Think Pair Share untuk Meningkatkan Hasil Belajar Siswa

[Title: The Implementation of Think Pair Share Learning Models to Improve Student Learning Outcomes]. The purpose of this study was to improve the learning outcomes of Class VII Students of SMP Negeri 1 Loura, the subject of Linear One Variable Equation through the Think Pair Share (TPS) Learning model. This type of research is classroom action research that is reflective by taking certain actions in order to improve and enhance classroom learning practices in practice and professionally. The subjects of the research were VII grade students of SMP Negeri 1 Loura for the Academic Year 2017/2018, amounting to 43 people. The data collection tools used were: tests and observations. Data analysis techniques were obtained from the teacher, student activity data and test results. The indicator of the success of this class action research is said to be successful if it reaches classical completeness of 75% with the Minimum completeness Criteria (KKM) 70. The results obtained, in the first cycle test students who completed reached 62.79% and incomplete reached 37.21%. While the second cycle of students who completed tests reached 81.39% and 18.61% of incomplete completed. And the average results of observations in the first cycle for the first meeting is 2.25 and for the second meeting is 2.63, and the results of observations in the second cycle for the first meeting is 3.00 and for the second meeting is 3.25. Based on the results of the study it can be concluded that the implementation of the TPS learning model can improve student learning outcomes

Enhanced magnetic moment and conductive behavior in NiFe2O4 spinel ultrathin films

Bulk NiFe2O4 is an insulating ferrimagnet. Here, we report on the epitaxial growth of spinel NiFe2O4 ultrathin films onto SrTiO3 single-crystals. We will show that - under appropriate growth conditions - epitaxial stabilization leads to the formation of a spinel phase with magnetic and electrical properties that radically differ from those of the bulk material : an enhanced magnetic moment (Ms) - about 250% larger - and a metallic character. A systematic study of the thickness dependence of Ms allows to conclude that its enhanced value is due to an anomalous distribution of the Fe and Ni cations among the A and B sites of the spinel structure resulting from the off-equilibrium growth conditions and to interface effects. The relevance of these findings for spinel- and, more generally, oxide-based heterostructures is discussed. We will argue that this novel material could be an alternative ferromagetic-metallic electrode in magnetic tunnel junctions.Comment: accepted for publication in Phys. Rev.

The ship recycling conundrum: an econometric analysis of market dynamics and industry trends

Ship recycling has received considerable attention during the last two decades for a variety of reasons and the industry is currently under a thorough scrutiny with the likelihood of the adoption of a new multilateral convention under the auspices of the International Maritime Organization (IMO). This study applies econometric modeling to a unique dataset to provide a holistic insight into the dynamics of the ship recycling market. The dataset contains information on 51,112 ships over 100 gt and includes 748,621 events over a period of 29 years. The binary logistic regression models used provide insights for a shipping-related sector that has received scant scholarly attention in the past. It is expected that these contributions will provide empirical support for the ongoing IMO discussions in this important field
