Hello If we have two bottles with solutions with HCL at different concentration. Can we produce energy out of it? How can I calculate how much? Thanks!

Hello I read several articles about controlled drug release from patches, liposomes, etc Can you tell me please which methods are available to control the release of a drug and what can trigger this release? I am interested in developed available technologies rather that something...

Mmm, that's not exactly what I mean. Let's say you want to completely block blood supply to prostate. If you block completely the prostate artery, do you achieve that? Or blood from different arteries will supply the organ? Or the same with a specific bone or with lungs or with bowel. In...

Hello! Is the blood supply to an organ done exclusively by one (or more) distinct arteries or there is extensive collateral supply from different arteries? For example, is lungs' circulation only from bronchial and pulmonary arteries/veins or there is collateral blood circulation as well from...

So, if I have a pipe that divides into two smaller pipes with some angle, and I but an embolus that will sit at the split and partially obstruct the flow, the pressure in the two smaller pipes will decrease?

The pump is centrifugal and the fluid is water, but it should be independent of this information. I was thinking introducing an obstacle in the pump to convert flow energy into heat, would that reduce pressure as well?

Hello! How can you do e.g. 756 x 675 mentally? Any good trick?

Sorry I was on an induction for the whole week finishing very late and now I am ill. We have a horizontal pipe which is connected to a pump and water flows. At some point of the pipe, the walls are rusty and it may break. Is there a way to release some pressure at that point? (I suppose...

Hello Can you tell me please in which diseases the solute (free circulating) antibodies are a major factor for their pathogenesis/pathophysiology? I read that for some diseases, it's mostly some types of cells that trigger/facilitate them and antibodies can be markers only. Also, I wonder if...

Hello We have a pipe that receives water at a constant rate. This creates pressure in the pipe. Is there a way to reduce pressure downstream? Which equations describe the factors that affect pressure? Thanks!

Thanks! What do I put for [E] if I have a porous material or surface where rhe enzyme is immobilised on and put in a solution of the substrate? Also, what are the units of V and how do I convert them into substrate moles per mg enzyme per minute? It seems v units are mM/sec which is not...

Hello! Can someone explain in simple terms the enzymology values of kcat, km and kcat/km? From what I gathered all mean how many substrate molecules are converted by an enzyme molecule per unit of time, is this correct? (let's say the conversion rate) The kcat is the conversion rate when...

exactly, thanks!

Hello, Once reading about renal function I think, I read that there are actually parts from organelles circulating in blood that have a specific name. They also function as messengers. But I cannot find anything about it now, any idea?
