Supercapacitors(SCs) are energy storage devices with the ability to charge and discharge at very high rates. The fast accumulation and release of charges occurs either electrostatically or electrochemically. There are two types of capacitors: electric double layer capacitors(EDLCs) and pseudocapacitors. EDLCs are the most commercially available.

Department of Energy of Philippines statistics reveal that from 2000 to 2010, the road transport fuel consumption and corresponding CO2 emissions have grown modestly with an annual growth rate of 0.5%. This modest growth is in contrast to the rapid increase in vehicle numbers, economic activity and in absence of implementation of comprehensive sustainable transport policies and options. The main objective of this research is to correlate official fuel consumption data (i.e. top-down) with bottom up quantifications and provide relevant policy recommendations. Based on the assessment of transport demand variables and review of policies and strategies, fuel consumption in transport sector was found to be growing at a much faster rate when compared to official estimates. Use of official data on fuel consumption in road transport sector may lead to serious errors. This has huge implications on policies and investments.

The post-operative patellar tendon length was studied to evaluate the possible tendon length change after anterior cruciate ligament（ACL） reconstruction with hamstring autografts. The Insall-Salvati index, modified Insall-Salvati index, curved modified Insall-Salvati index and Caton-Deschamps index were observed by MRI during a follow-up period of 12 weeks on 20 ACL reconstructed knees. The results showed no patellar baja or alta pre-existed on those ACL injured patients. After a follow-up period of 12 weeks, no patellar tendon length change was observed. It is suggested that the change of patella was not the primary reason that may contribute to the premature patellofemoral joint osteoarthritis after ACL reconstruction.
