The Mechanical Properties of Brass Alloys: A Review
Engineering ProceedingsBrass is a proportionate copper and zinc alloy that may be mixed to achieve a variety of mechanical, electrical, and chemical characteristics. Compared to bronze, it is more pliable. Brass has a comparatively low melting point (900–940 °C; 1650–1720 °F),

steel research international, EarlyView.A CALculation of PHAse Diagrams thermodynamic modeling for Fe–Sn–C system is carried out. The model and the developed database can be used to calculate phase diagrams and thermodynamic properties of this system over wide temperature/composition range, and a part of a larger thermodynamic database for steel and alloy system, and effectively used to ...

Linguistic Evidence Suggests that Xiōng‐nú and Huns Spoke the Same Paleo‐Siberian Language
Transactions of the Philological Society, EarlyView.Abstract The Xiōng‐nú were a tribal confederation who dominated Inner Asia from the third century BC to the second century AD. Xiōng‐nú descendants later constituted the ethnic core of the European Huns. It has been argued that the Xiōng‐nú spoke an Iranian, Turkic, Mongolic or Yeniseian language, but the linguistic affiliation of the Xiōng‐nú and the ...

Contract Labour, Job Quality and Turnover Intention—Evidence From Nigeria
Journal of Agricultural Economics, EarlyView.ABSTRACT Labour contracting, where intermediaries provide farmers with migrant workers, plays a central role in meeting the demand for seasonal labour on labour‐intensive farms. Yet this system poses underresearched challenges for both workers and farmers.

Hydraulic In Vitro Characterization of MR‐Conditional Blood Pumps
Artificial Organs, EarlyView.Cardiac surgery in neonates requires close placement of cardiopulmonary bypass machines due to limited blood volume, complicating MR compatibility. This study introduces three MR‐conditional blood pump prototypes. None interfered with MRI imaging, though RF‐related sensor effects remain untested.
