The Precedent set by Unprecedented Rainfall: Lessons to be Learnt From Disastrous Flooding in Pakistan.

Pakistan has suffered heavy losses due to the torrential monsoon rains of 2022. With obliterated infrastructure and rising disease burden, the nation is still reeling from the dismal aftermath. It is critical to understand that such catastrophes are not a 1-time calamity but are likely to become more frequent with growing severity of the climate crisis. These losses point to a more systemic problem that is a lack of preparedness, and without sustainable long-term measures in place, the nation remains just as vulnerable to the next 'unpredictable' weather contingency. Prior planning and effective allocation of resources can help develop a proactive response to future disasters of this magnitude.

Effect of fluoride on the corrosion behavior of Ti and Ti6Al4V dental implants coupled with different superstructures.

The effect of fluoride ion concentration on the corrosion behavior of Ti and Ti6Al4V implant alloys, when coupled with either metal/ceramic or all-ceramic superstructure, was examined by different electrochemical methods in artificial saliva solutions. It was concluded that increased fluoride concentration leads to a decrease in the corrosion resistance of all tested couples. The type of the superstructure also showed a significant effect on the corrosion resistance of the couple.
