MCA: Use discretion in issuing Covid-19 compounds to avoid another blunder

pic).
While stressing that MCA supports the government s war against the Covid-19 pandemic, Chong said the welfare of the public must not be sidelined in the process.
Chong was referring to several incidents where hawkers were fined RM50,000 for operating beyond 10pm, which is not permissible in states under the movement control order (MCO).
This incident should not happen again, so that the government will not be labelled as an evil government that has no discretion, he said during a press conference at MCA s headquarters on Wednesday (April 28).
We hope authorities will have more compassion in issuing compounds to those who violated Covid-19 SOPs. he added. ....

"Effect of WC particle size on microstructure and diffusion at the inte" by Gang Li, Hongmei Zhang et al.

Abstract
Tungsten carbide/high strength steel (WC/HSS) composites were prepared by cold pressing and vacuum sintering. The microstructure and micro-hardness of the composites with different particle sizes were analyzed by optical microscopy (OM), scanning electron microscopy (SEM), ultra-high temperature laser confocal microscope and microhardness tester. The results show that WC density tended to increase as the average grain size of WC decreased. When the particle size of WC powder was 100 nm, the density reached 91.22%. The micro-hardness of WC increased with the decrease of WC particle size. When the particle size of WC powder was 100 nm and sintering temperature was 1 320 ℃, the micro-hardness of WC reached about 1680 HV . The micro-hardness of WC near the bonding interface was higher than that of other parts. The microhardness of HSS core varied little with WC particle size, which was about 500 HV . When the particle size of WC powder particles was 200 nm, a transition ....
