- 2How do I improve the mobility of metal powder, especially the mixture of multiple-element metal powers?
how to improve the mobility of metal powder, especially the mixture of multiple-elment metal powers?
There are many factors influencing the mobility of the metal powder, such as particle size distribution, the powder surface and morphology. You can improve the mobility of powder by optimizing the particle size distribution. The spherical particles are always preferred. Besides, the annealing treatment at optimal temperature is also a good choice if possible.Following
- 7Can liposomes be formed using DPPC lipid only in acetate buffer pH 5.3?
I made liposomes using Ethanol injection method, I try DPPC (2.5, 3.4, 5 mM) in acetate buffer.
I fixed the volume ratio of Etoh : buffer (pH 5.3) to 1:20
but i think No Liposome were formed (20nm), I don't know where is the problem
if not how much cholesterol can i add to make it?
Michele, i tried adding cholesterol (5:3), it give me a size about 110 nm size and 0.3 PDI, i think this is good
However, i tried this to make a bilayer of this lipid surrounding chitosan nanoparticles, do you have any suggestionsFollowing

- 3Does anyone have a need for powerful, yet intuitive image analysis software?
On December 14th, 2015, we will release a free beta trial of MIPAR, a product we feel to be an extremely powerful 2D/3D image analysis software package. Its use of a 5-app, recipe-oriented architecture has enabled it to tackle segmentation problems few, if any, other packages could.
If interested, please visit www.MIPAR.us to learn much more, sign up for the free trial, and/or submit a test image! Please let me know of any thoughts you might have.

- 99+How do the economists define self-interest and rationality?
How do the economists define self-interest and rationality so as to make these concepts different from the animal instincts, beast behaviour, and barbarism? What is that which forms and what is that which does not form the self-interest? Moreover, are these the behavioural guides for all individuals? Are these the collective guides for policy making?
Given the propensity for free riding in each economic-beast, does not the collective policy results into a collective free riding of those who make policies over those who do not?
Dear Guy Jakeman
You have raised intelligent points. But in raising these points you have actually knocked down your very arguments. You said that taking a move to maximization, though it is an imperfect one, is a move aimed at a priori utility maximization. The imperfection is due to the constraints relating to time, information, knowledge, resources etc. So your ‘economic man’ is always and most of the time working on hunch and trial and error in a never ever equilibrating world that is again mostly of her own making. Rather, your ‘economic agent’ is consistently trying to maximize something that she herself does not know for sure what it is! Illusion after illusion and a cycle of never ending illusion! Moreover, is the agent working on her own or is she persuasively told to act in such a way is another unsure and unsettled issue.
- 1Which families of ionic liquids amongst the extensively used in research studies are more corrosive??
What is the reason of the corrosion of the ionic liquids.
I am trying to find the probability of ionic liquids to damage pipelines by their corrosive nature.
Generally corrosion studies are carried out with 3.5% NaCl solution as it simulates a coastal or underwater (sea/ocean) environments, for studying the effect of corrosion on structural and underwater pipelines.
HCl is very corrosive and it has ionic characteristics as well as covalent bond characters.
If you want to try a different salt, try a halogen salts of alkali metals.Following

I want to know is the broken down of BOA in graphene has been solved or not yet,
See the link
what are the other cases where the BOA is also broken down in them and Why
Ok, let's say it this way, I have a new model that may solve the Graphene breakdown for the BOA I just need to prove it by applying it on Graphene, Is any one interested to enter with me in a collaborative work, The model is there only I need to apply it through calculationsFollowing
- Chandravadan Trivedi added an answer in Arthrospira:1Does anyone know how I can avoid gliding of Arthrospira in plates?
Thank you so much
You may try this method. Apply a coating of egg albumin on the plate & place medium sized sand particles at a few places on the plate before albumin gets completely dry. Use preferably distilled water ( so as to reduce sp. gravity of medium) so that relative to density of the alga, the ratio becomes lower, & not the medium of sample collection & that too, minimum of it.
Once placed, some of the points of the algae will get tethered to the sand particles, which will prevent them from moving on the plate.Following

Which are you preferring to do : Qualitative studies for a difference equation without get the exact solution or getting the exact solution and then doing the analysis ?
Dear Dr Notiragayu
I think that this answer is not totally Correct .
I have some papers whose have given the exact solution in despite of they are with variable coefficients .

- 3How to have Affordable Housing for Low Income Groups in Indo-Pak cities?
what should be a viable and sustainable strategy for providing housing for low income housing? We all know land,cost reduction, technology, finance all are very important and developing connections between these dots is very important. But can anyone guide me some good work where these dots connection has been discussed and practiced particularly in India or Pakistan. Moreover, if some study which talks about connecting these dots along with city rethinking/redesigning is referred, I shall be thankful.

Main issue is long term sustainable AH which makes cities as places of innovation, inclusive, knowledge sharing...Following
- 4Does anyone know about incident wave frequency 11GHz-18GHz, Cu(copper) refractive index (including real part and imaginary part)?

I'm interested in how teachers might articulate a particular 'belief ' about teaching and learning - yet their practice seems to be at odds with this 'belief' ( observed practice) . My interest lies within the teaching of science and the assessment of inquiry skills.

- 4Does any one have questionnaire for individual differences in the classroom classroom?
Two of my undergraduate students are working on their graduation research. They need help
They want to find a questionnaire for individual differences. Any help please?
I suggest ask your students to generate their face to face interviews instead of questionnaires. Please consider other data collection tools, such as observation, thick description, discussion with teachers and friends. Hopefully they will give you ample evidence to form opinion about the differences. In a classroom what to focus? You may like to see my postings. Thanks!Following
- 5Is there public dataset for evaluating 3D segmentation?
I implement 3D segmentation and I want to evaluate my algorithm, I am looking about public dataset if it is available
In most of cases you have to normalize the voxel values first to keep in range i.e. 0 to 255.
Another hint: you may use empty square braces in imshow function to avoid showing the images in black and white.Following

- 1Is there any non-invasive (non-surgical) method for early mouse embryos retrieval ?
I need a non-surgical method for early mouse embryos recovery (morula or blastocyst stage) such as uterine lavage.
I have not heard but idea is not bad for someone to try by some fine device to flush uteri. Still there will be one disadvantage if some morulas are on the way to uteri or some embryos remains unflushed, the mouse may become pregnant, anyway. The cost of housing for full term needs to be considered.Following

- 4Reliability Analysis SPSS: corrected item-total correlations above 0.7. Keep or throw out analysis?
I am running a few reliability analyses on data regarding advertisements. The majority of the scales have items with corrected item-total correlations above 0.7. I was taught that items with item-total correlations above 0.7 are nearly measuring the entire scale itself. There is thus some redundancy.
Although the scales are reliable (90%+ Cronbach's Alpha), the quality of the scales can be improved. Do I throw out those highly correlated items -to -total or do I keep them?
Item-total correlations above .70 suggest me some redundance in contents/wording (they are high values). Anyway, I think you need to do "content analysis" to decide item selection. I encourage you to use both statistics and theory in your items/scale analysis.
Hope it helps!!
