Bonded labor, which is characterized by a long-term relationship between employer and employee, is usually solidified through a loan, and is embedded intricately in India’s socio-economic culture—a culture that is a product of class relations, a colonial history, and persistent poverty among many citizens. Also known as debt bondage, bonded labor is a specific form of forced labor in which comp...
In this research, the effect of temperature and time on the properties of AISI420/SAF2507 dissimilar joint produced by transient liquid phase bonding process was investigated. A BNi-2 interlayer with 25 μm thickness was inserted between two dissimilar steel samples. The bonding process was performed at 1050 oC and 1100 oC for different bonding times. The microstructures of the joints were studi...
Background. The aim of this study was to evaluate root displacement of the lower incisors fixed with FRC in different positions versus FSW retainers using the finite element method. Materials and Methods. 3D finite element models were designed for a mandibular anterior segment: Model 1: flexible spiral wire bonded to the lingual teeth surfaces, Model 2: FRC bonded to the upper third of lingual ...
silica-bonded n-propyldiethylenetriamine (7) is employed as a recyclable heterogeneous solid base catalyst for the synthesis of 2-amino-3,5-dicarbonitrile-6-thiopyridines through pseudo four-component condensation reaction between aromatic aldehydes, malononitrile, and 2-amino-thiophenol in refluxing ethanol. silica-bonded n-propyldiethylenetriamine showed much the same efficiency when used in ...
