A successful roof-top wind power project? [PDF]
, 2010 Roof-top wind power projects have a well documented record of very poor performance. The primary objective of this project has been to provide advice in the planning phase of a roof-top wind project to ensure its success.

Advanced Science, EarlyView.Drop‐location sensitivity remains a key barrier to practical droplet‐based electricity generators (DEGs). Here, a polydimethylsiloxane slippery covalently attached liquid (PDMS‐SCAL)‐coated interface promotes droplet sliding instead of splitting or bouncing, allowing stable electricity generation from randomly falling raindrops. The resulting PDMS‐SCAL‐

MN•CS•IO System: Cross‐Species Study for HBB Function in High‐Altitude Hypoxia Adaptation
Advanced Science, EarlyView.We developed an integrative mesh‐nanorod sorting, chitosan nanoparticle delivery, and intraosseous injection (MN•CS•IO) system to investigate HBB in high‐altitude hypoxia adaptation. Transplanting Tibetan animals' HBB‐modified Lin‐ cells into mice achieved 95.59% transfection efficiency and 8.15% HBB expression. High‐altitude HBB recipients upregulated

Model predictive control with inline parameter adaptation for direct crystal growth rate regulation
AIChE Journal, EarlyView.Abstract In batch cooling crystallization, many interactive factors, including supersaturation, reactor dimensions, and operating conditions, govern crystal growth and significantly influence product properties. Variables such as temperature or refractive index are used as surrogate control variables but have limitations in capturing growth rate ...

Shearer mining application to soft thin-seam with hard roof
Procedia Earth and Planetary Science, 2009 AbstractStudy status on shearer mining in thin seams in the world is introduced. Base on the geological conditions of instable and soft thin-seam with hard roof in Caoyao Coal Mine of Yima Coal Group, China, and combined with related parameters of strata behaviors at coal faces, the paper concludes that the strata control on the thin-seam coal face is ...

Analysis of Overburden Structure and Pressure‐Relief Effect of Hard Roof Blasting and Cutting [PDF]
Advances in Civil Engineering, 2019 When studying the pressure‐relief effect of hard roof blasting and cutting, the roof‐cutting position and angle obviously affect the stability of the rock surrounding the gob‐side entry (GSE). In this paper, control of the large deformation of rock surrounding the GSE is evaluated on the basis of the overlying structure and pressure‐relief principle ...
