  • Linas Balciauskas added an answer in Biodiversity:
    Does anyone know any specific method or questionnaire or protocol which can help to evaluate impact of conservation activities in a local area?

    We are encouraging local people to take the lead in protecting the biodiversity of thier forests. I would like to gradually evaluate without any bias if our action have an impact on the ground

    Well, you cannot ask directly. I just recently have read about your project in - you will not believe - Lithuanian language! So, it must be known also in other places? Then - do you have a sociologist in your team? If not, best idea perhaps is to have one (I do not mean employing, you may cooperate). Not only advice, but also participation of sociologist will save you time and efforts, you will not have to correct mistakes after questioning.

  • Sandeepa Wimalananada added an answer in Contaminants:

  • Luisiana Cundin added an answer in Mathematics:
    Is there a method for calculating zero-derivative points without using derivative?

    Characterizations of zero-derivative points of C1 functions in several variables, which do not explicitly require derivative, are known, see, e.g. "On the behavior of functions ..." Inter. J. Opt: Theory, Methods, Applications 1(2009), available on Google.They are also mentioned in some answers to the ongoing  RG question "Is there a book in English..." These results have been found useful for verifications of optimality, in sensitivity theory, operations research, economics, etc. How can  they be used to actually  calculate zero-derivative points?

    I am not sure but I see *node print at the end of the file. That seems to print the PORE PRESSURE and FLOW RATE at the node set named 'target_zone'. I don't know where is that node set you can find it from odb file. You will get the results of this *node print in *.dat file generated after the analysis.

    For PFOPEN, I think you need to create a path (search manual for how to create path) along the crack where you want to get the data and then extract XY data along that path. I can see PFOPEN as an element output.



  • Nina Baur added an answer in Online Surveys:
    Which online survey page has best output for SPSS?

    Hello dear ResearGaters,

    I am planing a quantitative study with open-closed type questions. I need to reach respondents from geographically big area, so i decided to use online survey. I have used some sites before, though I was not completely satisfied with data output for SPSS. Which Internet page would you recommend for surveys when You want to have data output for SPSS?

    Nina Baur · Technische Universität Berlin

    Dear Rūta,

    there is no perfect way to transform survey data to SPSS. However, I recommend Unipark - as it is one of the better software systems both concerning data protection law/ethical issues and let's you track response behaviour and you can do complex programming when needed (e.g. filters).

  • Gopalakrishna Palem asked a question in Existentialism:
    What are the pre-requisites for proof-by-contradiction to work?

    For example, assume two entities P and Q, where we are using 'proof-by-contradiction' to validate P (by using Q).

    Something like:

    • if P then Q;  
    • Not Q. Hence not P

    IMO, one can only use such scenario, when P and Q are independent of each other existentially.

    In other words, can one use proof-by-contradiction in cases where Q's existence is dependent on P's validity?

    For example, Q exists if and only if P exists.

    In such case does the proof-by-contradiction still hold valid?

  • Roland Iosif Moraru added an answer in National Identity:
    Will a multicultural policy succeed in a state built on national identity and on the ideology of one language, one state, one nation?

    The contemporary European model of nation-state is based on the ideology of one state, one nation and one language, so we can follow many conflicts involving nationalism and multiculturalism. How can we overcome this contradiction and to ensure equal rights for all? After all, multicultural environments, today and in the past (before the European model of nation-state), are a reality.

    Roland Iosif Moraru · University of Petrosani

    Dear Doego

    The article at link bellow states that "despite substantial evidence that policies allowing legal and political accommodation of ethnic diversity are working, a chorus of political leaders in Europe has declared multiculturalism a failure — in effect mischaracterizing the multiculturalism experiment, its future prospects, and its progress over the past three decades."

    What is the best method to analyse the expression of miRNAs in the cells?

    I want to analyse the expression of few target microRNAs in the treated and untreated multiple myeloma cells. What is the best method to analyse miRNA expression apart from whole miRNA arrays?

    Prabu Paramasivam · Madras Diabetes Research Foundation

    Dear Prahlad

    MicroRNA expression from treated and untreated in cancercellline, best option is Real time PCR or Qpcr.

    RNA isolation and followed by cDNA conversion and then you have to select any one chemistry method to use qpcr etheir  Sybr green or Taqman probe.

    Different company providing microRNA primer examble Exiqon, Qiagen and so on.

    After qpcr analysing your result , they are two option available first one absolute quantification where we use known concept of standard, and next on relative quantification its mostly used to one compare to control how many fold change increase or decrease.

    Relative quantification is best method to analysis Mir expression from treated or untreated cells.

  • Rakesh Kumar Meghwanshi added an answer in Bacterial Taxonomy:
    Can anyone help me identify this bacterium?

    Hello Members,

    I happen to come across some pink coloured colonies on some left over yoghurt. The colonies seem really interesting as the colour is bright pink and the entire yoghurt pot has been stained pink. Colonies are smooth and rounded, but smaller colonies appear as triads or tetrads (as if the cells are triads and then grew into a colony later.) I am tempted to think that this might be some Serratia strain but, the colonies seem to grow well in low temperature.

    I don't have access to a lab and hence cannot characterize the strain any further. Please see the attached picture and could someone let me know if they have come across anything like this before.

    Alternatively, I am also happy to send the culture to some lab who would be interested to work on this culture.

    Thanks in advance,
