The rate of failure of community based LED projects aimed at creating jobs and alleviating poverty is very high in rural communities. 

How to design AC LED driver without Inductors and capacitors?

I turned on an LED and found the chip architecture was imaged onto the wall. this could lead a big trouble when I wanted to use this LED, but I couldn't know this via reading the spec. did anyone have the similar experience, how to resolve this problem ?

what kind of simulation i can use to simulate design contain LED and CMOS and nanoparticle sheet?

Actually I am just missing the design equation to find out the No of turns in primary and secondary winding

I am conducting a scoping review of post-therapeutic rehab (>3 months post-op), community-based (not in hospital/clinic settings), recreational (not further therapy sessions) and fitness instructor led (not physio/PT) exercise or physical activity programs designed for or appropriate for adults after hip and knee arthroplasty. These are programs aimed at motivating and supporting people to continue to recover after TJA and regain confidence being physically active in recreational settings.

How to design LED light pipe for electronic device use? As set-top box, HDD carrier, power adapter. AP router ...etc. Where can I get more detail documents of design rules/guideline? The material is plastic of LED light pipe. 

What criteria do you use to decide which number will be in control and treatment group?

Dear community of researchers,

I am currently working on a small research project that will explore community- and patient-led strategies for increasing referral of diabetes and hypertension and raising awareness of these two diseases in Mozambique, a highly resource-constrained country.

I would like to ask:

- does anyone have knowledge on patient-led referral strategies and advocacy activities? If so, could you please share any relevant links and/or are you aware of any recommendations on this from international health organisations?

- do you believe that involving patients in such activities would be ethically appropriate? Why/ why not?

Thank you in advance for any replies.

Regards,

Chiara

Can we use LED light for solar simulator if the purpose is to experiment solar hot water heater system?
