The corrosion behavior of Fe-containing directionally solidified (DS) and centrifugally cast (CC) Al-Si-Cu-Zn alloys with either Co or Ni additions has been investigated.Electrochemical and immersion corrosion methods were used to investigate the corrosion behavior in 0.6 M NaCl after short (1-h) and long (30-day) exposure periods.The employed soli
Unicellular organisms such as ciliates are largely neglected in research on adaptive developmental plasticity, although their nuclear dualism offers ideal circumstances to study development outside an embryonic context.Here, we gain first insights into the ability of the ciliate Paramecium to develop potentially adaptive phenotypic changes in respo
To investigate the impact of sulfate corrosion on the performance of shaft lining Machines concrete under sustained compressive loads, this study immersed samples in a 10 % sodium sulfate solution after subjecting to sustained compressive loads of 0.2fcand 0.4fc.The variation in compressive strength, ultrasonic velocity, and dynamic elasticity mo
Background: Despite the well-known impact of rape on mental health and the widespread problem of rape in South Africa, mental health services for rape victims are scant and not a priority for acute-phase services.Survivors encounter multiple mental health struggles in this period including adherence to the post-exposure prophylaxis drugs to prevent
