One of the most critical problems in industry is wear materials. Graphene, as a tribological coating, has shown tremendous impact on sliding surfaces. In this work, few layers graphene were grown nodular cast iron substrate, material used camshafts. The studied synthesis parameters rapid thermal chemical vapor deposition (CVD) furnace and quality final coating are presented. influence hydrogen ...
Abstract In this paper, the effect of microstructure a thick-walled rotor shaft for wind turbines on fracture toughness properties has been investigated. The relevant nodular cast iron grade EN-GJS-600-3 was processed using chill casting technology. Due to different solidification conditions over wall thickness, heterogeneous microstructures were formed. To illustrate influence gradient caused ...
BACKGROUND The incidence and potential risk factors for the recurrence of benign nodular goitre after unilateral thyroidectomy are not clearly defined. The aim of this study was to assess the rate of progression of nodular goitre in the contralateral thyroid lobe and of hypothyroidism requiring replacement therapy after unilateral thyroid lobectomy for benign nodular goitre. PATIENTS AND METH...
Objective. It has been testified that iodine regulates thyroid function by controlling thyroid-restricted genes expression and is closely related to diffuse goiter and thyroid dysfunction. However, the effects of follicular lumen iodine, the main form of iodine reserve in the body, on thyroid-restricted genes in nodular goiter are poorly understood. In this study, correlations between follicula...
