Abstract. A retrospective suicide study revealed that the Forestry Commission car parks in the New Forest in southern England were a previously unrecognized magnet for nonlocal suicides, attracting as high a proportion of “visitors” (35/43 in 1993-97) as among suicides who jumped from the cliffs at the infamous Beachy Head (39/48 in 1993-97). Over 95% of the car park suicides died from car exhaust gas poisoning. A multiagency initiative aimed to reduce the number of suicides in the 140 New Forest car parks where restricting access was impossible, and environmental issues paramount. Signs displaying the Samaritans' national telephone number were erected in the 26 car parks in which 50% of the car park suicides had occurred. Numbers, location, and residence of all car park deaths were monitored for 3 years. Corresponding changes in other forest registration districts were also monitored. During the 3-year intervention period the number of car park suicides fell significantly from 10/year, 1988-1997, to 3.3/year. The average annual total number of suicides in the New Forest registration district also decreased. No significant changes were found in comparable forest districts. The number of suicides in the New Forest car parks remained low during the 2 years following the evaluation.

This work covers waste energy utilization of the combined power cycle by using it in the candle raw material (paraffin) melting process and an economic study for this process. After a partial utilization of the burned fuel energy in a real bottoming steam power generation, the exhaust gas contains 0.033 of the initially burned energy. This tail energy with about 128 ºC is partly driven in the heat exchanger of the paraffin melting system. Ansys-Fluent Software was used to study the paraffin wax melting process by using a layered system that utilizes an increased interface area between the heat transfer fluid (HTF) and the phase change material (PCM) to improve the paraffin melting process. The results indicate that using 47.35 kg/s, which is 5% of the entire exhaust gas (881.33 kg/s) from the exit of the combined power cycle, would be enough for producing 1100 tons per month, which corresponds to the production quantity by real candle's factories. Also, 63% of the LPG cost will be saved, and the payback period of the melting system is 2.4 years. Moreover, as the exhaust gas temperature increases, the consumed power and the payback period will decrease.
