The document examines the vulnerability of cotton crops in China to hail, highlighting its significant agricultural importance and the economic losses caused by hail disasters. An integrated methodology combining historical records, field investigations, and experiments was developed to assess cotton vulnerability at different growth stages, identifying key periods for disaster mitigation. Results indicate that the stage of seedling and boll opening are particularly sensitive to hail, emphasizing the need for risk governance in those periods.
The document discusses how disasters impact human security across several dimensions: economic, food, health, environment, personal safety, community, and political. It provides the example of Hurricane Katrina in 2005, noting its 100-year storm impact resulted in tremendous losses and increased poverty rates in New Orleans. Specifically, it states the city's population decreased by 29% and there were 118,000 fewer African American residents after the storm.

The document describes modifications made to a log periodic dipole antenna (LPDA) to make it more portable while maintaining performance. Specifically:
- The original LPDA had a boom length of 5.5 meters, which was reduced to 3.11 meters to improve portability.
- 38 elements were used on two booms to cover frequencies from 45MHz to 1000MHz. Plastic insulation and a spacing factor of 0.08 were used.
- The antenna was connected to a CALLISTO spectrometer via coaxial cable to convert radio signals for detection and measurement of solar bursts.
- Initial results showed the modified compact LPDA operated successfully while maintaining the desired frequency range and directivity.

This document summarizes a study that compares the effectiveness of three forms of Moringa oleifera extracts for removing turbidity from water: shelled blended powder, deoiled powder, and purified protein powder. The study found that the purified protein powder was the most effective at removing turbidity, followed by the deoiled powder and shelled blended powder, but the protein powder required the lowest dosage. The study aimed to determine the optimum dosage of each extract for water samples with initial turbidities of 50, 150, and 450 NTU and also performed a cost analysis comparing the extracts to alum, a common chemical coagulant.
This document discusses how weather and climate data can inform decision making across timescales from days to decades. It provides examples of how climate services can support agriculture, disaster risk reduction, food security, and water resources. Key points include using past weather observations to define climate risks and inform crop choices, predicting hazardous weather to issue timely warnings, using monthly to decadal predictions to warn of drought, and applying regional climate models to climate change adaptation decisions for water resources. The document also outlines delivering forecasts from hours to decades and developing partnerships to strengthen climate services.
