Dash for gas leaves Earth to fry

The aggressive expansion of ‘unconventional natural gas development’ — more widely known as ‘fracking’ — has triggered protests across Europe. The concern is not just the direct impact on the environment but the production of fossil fuel in quantities we can no longer afford to burn, along with the side effect that the availability of cheap gas undermines the economic viability of sustainable e...

Lateral gas diffusion inside leaves.

Diffusion of CO2 inside leaves is generally regarded to be from the substomatal cavities to the assimilating tissues, i.e. in the vertical direction of the leaf blades. However, lateral gas diffusion within intercellular air spaces may be much more effective than hitherto considered. In a previous work it was demonstrated that, when 'clamp-on' leaf chambers are used, leaf internal 'CO2 leakage'...

طراحی حرارتی – سیالاتی، ابعادی ریکوپراتور گاز به گاز (gas to gas) میکروتوربین 200 کیلو وات

یکی از راههای افزایش راندمان حرارتی واحدهای میکروتوربینی، استفاده از حرارت گازهای داغ خروجی از توربین می باشد که این گرما در مبدل حرارتی ( ریکوپراتور) به هوای خروجی از کمپرسور منتقل شده و بدین طریق میزان سوخت مصرفی سیکل کاهش یافته و در نتیجه راندمان این واحد ها افزایش می یابد. ریکوپراتورها مبدل های حرارتی گاز به گاز فشرده¬ای هستند که با نسبت سطح به حجم بالایی، میزان انتقال حرارت ما بین گاز خروج...

The U.K.’s ‘‘Dash for Gas’’: A Rapid Evidence Assessment of Fracking for Shale Gas, Regulation, and Public Health

The evidence on public health regulation of the unconventional gas extraction (fracking) industry was examined using a rapid evidence assessment of fifteen case studies from multiple countries. They included scientific and academic papers, professional reports, government agency reports, industry and industry-funded reports, and a nongovernment organization report. Each case study review was st...
