- 10What is wisdom?
Philosophic, religious, and opinion responses are acceptable.
In my opinion, wisdom is knowing what you do not know and accept that maybe the only thing we can do with ignorance is learning to live aware of it.
- 4Can I use heptanoic acid as a standard to quantify n-alkanoic acids in air samples PM10, collected on quartz fiber filter paper?
I am doing analysis of PM10 collected on Quartz fiber filter.I am expecting organic compounds like n-alkanoic acids decanoic acid, dodecanoic acid etc...I have only one standard that is Heptadecanoic acid.Could i use this chemical for quantify all the acids by making calibration curve from this standard.
I dont think so. I analysed monocarboxylic acids (C8 - C20) 5 years ago. I derivatized them into methyl esters by BF3/methanol and the peak area was different for different acids. The peak area of C16 was the biggest.
Rastislav.... PM10 means particles less than 10 micrometers. PM is Particulate Matter.Following

- 7Do you think the Zika virus leads to microcephaly?
How good is the science linking the Vika virus to microcephaly and other neurological defects in babies?
This is not my field at all, but in Argentina there are lots of news on zika in Brazil -where many Argentinians usually go for summer vacations (it is summer here)- and all the information underlines that microcephaly has been clearly associated with zika, to a point that some people advise pregnant women -I think with less of three months of pregnancy- not to travel to risk zones.Following

- 1Can somebody provide me a stratigraphic column of Holy Cross Mountains of Central Ppland?
I'm in need of a stratigraphic column of Holy cross mountains in Poland. I want to have a lithostrat column that displays all rock units in Kielce and Lysogory regions. There are some papers but I could not compile column of each region separately.
I would be grateful if someone give me a link or a paper or a map that I can get what I'm looking for.
Thanks for your concerns.

How to increase creativity, imagination and innovative ideas or innovative things?
Han Ping's 3rd response is so important. Once you move out of your area of expertise, you make discoveries but also create new partnerships, new synergies, new connections. Connect with people who view the world differently
Ask 'Why' and 'What if?'
Look for what is missing rather than what is there. Look closely at the spaces between things
Be playful, tinker with ideas, make mistakes, make messes take risks as Ian and Han Ping suggest
Be surprised by small things you observe or hear or touch

- 10How do I measure/asses entrepreneurial skills/competencies of university students?
Published research on this will be helpful.
You can asses entrepreneurial skills/competencies of university students by giving them practical task: 1. to prepare business plan for start-up company, 2. make competition within the group; 3. make notes on the best ideas and solutions, bearing in mind that the idea is realizable; 4. make them vote for the best business plan, with the explanations, why is that plan the best for them 5. go through the best business plan and identify the best parts (financial, human resoures, organisation, marketing, networking, market research etc).Following
- 2How to pretreat paper mill waste (cellulosic waste with higher ash, moisture and static energy) avoiding agglomeration to reach low particle sizes?
I have a question about paper mill waste. This byproduct is a cellulosic waste with higher content of ash and moisture.
We have had problems grinding this dry waste due to its static energy. After grinding the solid waste, the particles are agglomerated; therefore this situation avoid to feed a fluidized reactor.
So, I would like to know if anyone knows how to pretreat the waste avoiding the agglomeration for reaching low particle sizes that can be fed in a fluidized reactor?
Thank you in advance for your attention and guidance.

- 3Can anyone please help me find where I can find a complete dataset of historical (1970-2015) homelessness population by county or by city in the U.S?
Been browsing all these Census and HUD websites for datasets but no luck. They all have reports and even datasets but not what I am looking for. I really need to get the number of homeless people (point in time) in each county (or city and state if county-level is impossible to get) from the 1970s (or earlier) to 2015. Most of the datasets I got so far from every webpage I can google only give me pieces of that. Thank you.
Thank you very much Terry, will keep in touch. All the best to you too.Following

I am carrying out a research on “Postgraduates’ perceptions of the usefulness of Web 2.0 applications to facilitate collaborative learning in their university". The aim of the research is to investigate which Web 2.0 tools are used generally by post graduate students of various disciplines and to assess their usefulness as well as to explore how the collaboration of knowledge can be made productive in collaborative learning.

- 12Does National Water Documents need to revise?
National Water Document (NWD) of Iran was prepared more than 2 decades ago. NWD is a basis of set aside irrigation water to farmers now and we want to know it is accurate or not (Dose it change!)? Is it necessary to revise it?
Masaud, what you referred that applied water use efficiency is very relevant but that efficiency value for a crop at a location will depend upon the soil texture also, which would greatly define the water holding and drainage losses, accordingly variable need of water for attaining a given value of ET for a target yield of a crop,
we have to take care of this aspect too.

- 6Has anyone conducted water productivity calculations?
I wanna know about different method regarding water productivity calculations.
Neda, very good question raised by you, if we see the water used for one kg of rice production, it is very large, but important from food security point of view.
if rice yield is 6 t/ha, water through ET loss is 60 cm, means 6000 cubic meter of water per hectare. So for 1kg of rice, we need 1 cubic meter of water as ET, 1000kg of water. But for this much ET requirement we need to apply more water as drainage also is taking place, so large amount of water, but we have not to compare with water use efficiency of other sectors, as food security is the vbasic requirement
We can easily compute the water used in a given region if we know the production of different crops in that region, on the method as indicated above

- 4What is meant by Double loop and Single loop?
Can you please show the difference between them? it is related to reflective practice.
in order to show the difference between choices in a multiple choice question you would be sensible to use the one way chi squared test. This is the most conservative and sensible choice especially if you are not really genned up on statistics. To then doemonstrate the causality for this is not a matter of statistics but of having a valid hypothesis coming from some theory that you can show is chosen most frequently across the range of questions.Following
- NewWhy the effect of force is different than the effect of displacement?
I am modeling a human spine. I am applying displacement from top side and fixing the bottom and the model is working properly but when I change the displacement to concentrated force it is dying because of max penetration error and element distortion. I tried to apply very very minute amount of force which again caused my model to die. I wanted to know why the effect of force and displacement should not be the same in a model while both are at the same direction?!Following
