Among several additive manufacturing (AM) methods, binder-jetting has undergone a recent advancement in its ability to process metal powders through selective deposition of binders on a powder bed followed by curing, sintering, and infiltration. This study analyzes the impact of various process parameters in binder jetting on mechanical properties of sintered AM metal parts. The Taguchi optimization...
Three different PV systems were evaluated to compute degradation rates using four different methods and the methods are: I–V measurement metered raw kWh, performance ratio (PR) and performance index (PI). I–V method, being an ideal and the best method for degradation rate computation, was compared to the results obtained from other three methods. The median degradation rates computed from kWh method...
Grb7 is an adaptor molecule mediating signal transduction from multiple cell surface receptors to diverse downstream pathways. Grb7, along with Grb10 and Grb14, make up the Grb7 protein family. This protein family has been shown to be overexpressed in certain cancers and cancer cell lines. Grb7 and a receptor tyrosine kinase, ErbB2, are overexpressed in 20–30% of breast cancers. Grb7 overexpression...
There are huge potential for hydropower development in Himalayan region in general and Nepal is particular. However, there are also technical challenges for hydropower development due to sediment erosion problem. Erosion not only reduces efficiency and life of hydropower turbines but also causes problems in operation and maintenance. A large number of factors can influence the process of sediment...
