- How can I calculate inertial and viscous resistance coefficients in porous media?
I want model flow through porous media by fluent.
tnx for all your advise
i think ergun equation use for gas flow through porous media but in my case i want to model nano fluid through porous media so i understood from all of your comment i can use thise(inertial resistance=0 and viscous resistance=1/a where a is permeability) for laminar flow through porous.is this correct?Following

- Do the effects of mind on matter as demonstrated in the experiments of Radin et al (Physics essays 2012 & 2013) herald a new scientific paradigm ?
This refers to the recent experiments of Radin et al :
1) D. Radin, L. Michel, K. Galdamez, P. Wendland, R Rickenbach and A. Delorme
Physics Essays, 25, 2, 157 (2012).
2) D. Radin, L. Michel, J. Johnston and A. Delorme, Physics Essays, 26, 4, 553 (2013).
These experiments show that observers can affect the outcome of a double slit experiments as evidenced by a definite change in the interference pattern.
It requires urgent attention from the scientific community, especially Physicists.
If these observed effects are real, then we must have a scientific theory that can account for them.
Dear Jürg Martin Fröhlich ,
Science is limited to provide models with some reference to aspects of the world we can measured. I am saying that Mind, Experience, Consciousness, Awareness are not conceptually describable by such models. We cannot and will never come up with a concept of what is redness. If someone would never had eye, no knowledge about vision would give the person a clue about the experience of redness. We can say a lot of thing about what are involve in colour vision and I studied this field for several years but none of it explain redness. The robot I design to pick up mature tomatoes had no experience of redness whatesover although it was able to pick up tomotoes that you and me see/experience as red. We can even imagine and dream of red things. Nothing in what we know about the body explain why we are aware and conscious.
I will now quote one of the best visual scientist of our time:
''Here is a basic experiment:
Open your eyes in broad daylight, notice what happens.
The result may hardly prove amazing to you:
you are likely to see the scene in front of you,
at least, when you are not blind, inattentive, hallucinating, and so forth. Yet
this experimental result should appear amazing in view of the fact that science
has no clue of how to account for it!
Science can only repeat the long familiar story involving the physics of
electromagnetic radiation and its interaction with matter, the optics of the
eye, the neurophysiology of the brain, and so forth. Such stories allow you
to understand causal connections between the scene in front of you, and electrochemical
events inside you skull. This is by no means a minor feat, it took
centuries of intellectual labor. So far so good. But beyond that anything else
that might be said is mere mumbo jumbo to the honest scientist. The visual
awareness of the scene in front of you is literally magick, in the sense of being
beyond any (including future!) scientific understanding.'' jan koenderink
- How can I purify and isolate antibiotic compounds?
The antibiotic compound was observed from endophytic bacterial isolates isolated from Metroxylon sagu (sago palm)
Dear Irson Thurs Doria,
I can give you details under following points,
1. Grow your microorganism in suitable culture medium till the OD reach above 2.0 at 600 nm.
2. Collect the culture supernatant and down concentrate it ten fold using rotary evaporator.
3. Solvent extraction: Using organic solvents like acetone (ice cold), precipitate out high molecular weight compounds. Try for 40, 60, 80, 90 & 100 % acetone precipitation. Each fraction need to be screened for its activity. Generally the antibiotics are low molecular weight compounds and it would come in 80 or 90% supernatant.
4. Remove the acetone form active fraction using rotary evaporator.
5. The active fraction can be now passed to either ion exchange (cationic or anionic) or hydrophobic column (C18 or amberlite XAD-4 orXAD-16) followed by preparative HPLC.Following
- Any scale for postgraduate (by research) students (management) performance?
Looking for factors affecting postgraduate by research students performance. The respondent is business/management postgraduate students. Any measuring scale?
Thank you in advance
Output of research take its own time, hence performance of student (research scholar) should be measured owing to short run and long run perspectives. in long run quality of research publications and its utility to respective stakeholders is performance measurement. in short run quality of work done at excelling stages of research be measured by students and research supervisor. the average ratings of student and supervisor can be termed as performance measurement.Following

- What is the importance of calcium nitrate in plant growth ?
i would like to know the importance of calcium nitrate to plant . i know that this fertilizer is made up of two nutrients : nitrate and soluble calcium . a biochimical response should be appreciated to know how green plants uses these two nutrients . thanks.
Thanks Maher. Another very intriguing issue regarding calcium nutrition of plant , i missed in my earlier communication , is the tripartite relation between calcium , magnesium and potassium . Potassium on one hand , is balanced by concentration of calcium and magnesium on the other hand . This relation operates at both the levels, soil and in plants system. Soils rich in exchangeable-K, especially in those soils having illitic mineralogy , excess of k has to be balanced by addition application of Ca plus Mg , if the maximum response of these nutrients has to be harnessed.Following

- What are the methods used for map merging in swarm robotics?
In multirobot system, every robot(agent) explores the environment independently and creates the map of environment wherever it traversed across. Maps created by multiple robots are then merged to get the map of overall environment. To do this map-merging, I believe there are various methods used. I would appreciate if somebody explains these methods and merits and demerits of each method.Following
- How can we calculate the least spacing distance between PV modules to minimize shading effects?
I have read many papers about shading and many textbooks and handbooks in PV systems. No reference has ever given a clear procedure for such a problem. Are there any rules of thumb for this?
there is so little written about it, because it is a basic geometric task to be fulfilled.
Input parameters are the geographic position and the PV-Module dimension.
If you know both, it is simply calculating the height of the triangle formed by the PV-cell and the length of the shadow it throws.
published 1998, has a drawing on the very first page to explain the correlation. I'm sorry it's in German only but math and figures should be helpful.Following

Dear Mallamma, What you write "collection of singleton sets is an open cover for infinite set X which has no subcover."

- Anyone familiar with variation in Microfluidic mixing?
Suppose I want to mix two fluids in a microfluidic device, both fluids having the same inflow rate. After the two fluids have thoroughly mixed and reached the equillibrium concentration, I decrease the flowrate for both fluids, at the same time, to a value much lower than the previous flowrate at which equilibrium was reached. My qs is, whether the equilibrium position will be disturbed, and mixing will vary after I change the flowrate to the lower value??
For first part of your question, Comsol simulation can give you an answer. But it depends on how you "switch" from high to low flow rate. There is something called ramp & step function, which defines the rate of change of your flow rate (when you go from high to low). A sharp ramp might not give you a reasonable answer since in real world situations when you ramp down flow rate there will always be a "capacitance" involved.
Pe depends on your characteristic length (not length of channel). Usually this depends on depth/diameter of channel (average length two layers/laminae of flow have to travel to mix). So low channel length does not correspond to low Pe. So for two channels with same cross-sectional area, the Pe will be same. I could not understand last line of your question.Following

- How can I remove contamination in 5500 Qtrap?
I have very low sensitivity and see charging, but the normal source cleaning (curtain plate, oriface plate and Qjet) hasn't solved the problem. Is there something I am missing?
I would check the ESI capillary (might be blocked - try cleaning in an ultrasonic bath) and whether all small O-Rings in the source are still there (it happened once that one of the small amber coloured O-Rings came off, which caused intense signal drop in the negative mode).
Another issue our service technician usually checks are polarization effects. Try a Q1 scan in pos mode, quickly change to neg mode and see whether there is an initial increase and then a drop. If this is the case, you will pürobably need the service technician.Following

- Has anyone ever rigourously proven the distance formula before?
The only proofs I ever saw relied on intuition. The proof by similar triangles did something sort of like assume without proof that distance satisfies the following conditions:
- The distance of every nonnegative real number r is r.
- The distance of any complex number is a nonnegative real number.
- The distance of any complex number is equal to the distance of its complex conjugate.
- For any 2 complex numbers, the distance of their product is equal to the product of their distances.
The proof by area assumes without proof that a rotation never changes the area of an object where a rotation is defined to be a complex multiplication by a complex number with a distance of 1. Maybe the facts that those 2 proofs assumed have been previously proven.
Except for the page I wrote myself at https://proofwiki.org/wiki/User:Blackbombchu/Sandbox/Complex_magnitude_is_distributive_over_multiplication, I never saw any pages that define the distance of (x, y) to be sqrt(x^2 + y^2) without justification then prove the fourth condition from it.
I never saw any full proof in pages other people wrote: only in ones I wrote myself such as http://speedydeletion.wikia.com/wiki/Distance_and_rotation.
Perhaps just like some mathematicians don't feel the need to understand a mathematical proof of a statement when they have a computer-assisted proof, some mathematicians don't feel the need for a proof that there exists a distance function satisfying those 4 conditions when they instead have a physical proof, which is that they never observed a rigid object make an operation other than a rotation.

- Can someone suggest a clinician rating scale for dissociation and pseudo hallucinations?
We are inexperienced researchers and need help. We are interested in the phenomenology of pseudo hallucinations. We believe that clinicians can differentiate the experience of auditory hallucinations and pseudo hallucinations, possibly through features of dissociation. It is just hard to operationalise. Any advise would be great
Sorry I need to practise my typing! We did a simple project using the PSYRAT comparing hallucinations in PTSD with dissociative features DSM 5 and schizophrenics. We found similar features in both experiences but a very significant increase in delusions in schizophrenics. We want to continue our interest in an increased but still keep the project simple. We are thinking of looking at complex PTSD and borderlines and using the PSYRAT again with an instrument that assesses dissociation. I know it is a murky areaFollowing
