  • Sunil Kumar KN added an answer in Cosmetics:
    Fat-Oil soluble proteins or fractions?

    In cosmetic preparations in particular skin care products Fat-Oil soluble specific proteins are required, but how can this be dissolved? Which agents are to be used and what is its safety? 

    Sunil Kumar KN

    If those fat soluble proteins (FSP) are from some specific vegetable oil like oilve oil, the source oil can be used as such in the form of an ingredient (in fact there are creams with olive oil, almond oil etc). If the FSP/lipoproteins has to be isolated from specific oil of your interest, you have to precipitate it from petroleum ether soluble portion of the oil, using water saturated n-butanol. The precipitate thus obtained will have protein as well as carbohydrates, the lipoproteins have to be further separated using starch gel gel electrophoresis.

  • Hakeem Ayomi Sanni added an answer in Fixed Cell:
    An addendum to my earlier question?

    The idea of fixing the cells with 4% Paraformaldehyde/ ethanol is to make sure the cells do not wash off and are still present during the whole process .
    So if I wanted to do this experiment the steps I would follow would be to

    1. Remove media in which cells are initially growing
    2. Wash gently with PBS without disrupting cells too much
    3. Fix with 4% PFA for 10mins at room temperature
    4. Incubate with mix of Calcien-AM and EtBr in PBS/serm free media for 30mins @ 37degrees

    Now my doubts are should i skip step 3 and just go directly to step 4 or what other steps do I need to include so my staining works perfectly.

    Hakeem Ayomi Sanni

    Hi Rafik,

    I am trying to understand how the setting of inlet in the FLUENT, specifically, the Velocity Magnitude and Direction. Someone could explain me, please?
    I'm working in 3D domain.

    Dong-Bin Kwak

    Dear Bianca Hülle

    set the boundary condition : velocity inlet first, 

    and then, in the Momentum tab 

    you specify Magnitude and Direction in the Velocity Specification Method tab 

    you can specify the value, what you want to simulate. 

    If you need some additional help, you can ask anything about this.

    From Dong-Bin Kwak.

  • Mohammad I Al-Wabel added an answer in Biochar:
    Can biochar be an alternative to Soil organic matter?

    Keeping in view the nutrient and water holding capacity and effects on microbial activity of soil amended with Biochar, Can Biochar be an alternate to SOM?

    Mohammad I Al-Wabel

    I dont think the biochar will replace the OM in soil as it is more stable and will not add any material to the soil with decomposition.

    It is good to enhance the soil charac. but still soil need OM for elements, while biochar is not a good source for this

  • Krishnan Umachandran added an answer in Sprinkler Irrigation:
    Is there a paper about comparison of furrow, drip and sprinkler irrigation?

    I need papers or your answers about the comparison between these methods of irrigation particularly about soil moisture and nutrient movement, as I need that at my Ph.D. studies 

    Krishnan Umachandran

    Irrigation scheduling is to increase efficiencies by applying the exact amount of water needed to replenish the soil moisture to the desired level. Appropriate irrigation schedule saves water and energy. Therefore, it is important to develop irrigation scheduling techniques under prevailing climatic conditions in order to utilize scare water resources effectively for crop production

    Currently I am studying on pediatric thyroid cancer. In my study, pediatric thyroid tumors were significantly larger than adult tumors. This finding was also noted in a number of previous studies. I tried to find out a possible answer for this finding but i could not find the answer in previous studies or even narative reviews. Can anyone help me to answer or suggest related articles?

    Thanks a lot ;)

  • Casey Furlong added an answer in Water Resources Management:
    What are some of the major challenges in regulating water services?

    I am looking at the application of regulation to the water sector drawing on both local and international experiences and identifying similarities and differences in regulatory approaches across sectors. Other queries include: Can an “independent” regulator regulate a state water company and what are some of the implications and challenges?

    Casey Furlong

    Whether independent regulators are useful or not is an interesting question. Firstly it needs to be made clear that there are multiple types of regulatory functions in the water sector.

    I think most people would agree that an independent regulator is important for environmental regulation. Someone needs to set limits on the amount of nutrients that can be safely directed into rivers, lakes, and bays for example. These limits then need to be applied to all water utilities fairly, implying the need for independent regulators such as the EPA.

    Implementing an independent regulator for financial regulation is is far more difficult to achieve. I know in the UK this has been an issue, where public regulators play cat and mouse games with private water companies in regards to how they set prices, how much they reinvest in infrastructure, and how much they are allowed to profit. In places where water utilities are not privatised, independent financial regulators are sometimes charged with deciding whether water utilities are building unnecessary infrastructure, or doing unjustified spending, but they do not always have the technical expertise to seriously review utility infrastructure proposals.

    In the Australian electricity sector independent financial regulators have an extremely difficult time setting electricity prices for different areas. In one case reported in the newspaper I remember the regulator changed the price, and a private company lost a huge proportion of its profits in an instant.

  • Arunima Haldar added an answer in Corporate Governance:
    What is the relationship between Debt to Equity ratio with board governance and audit committee independence?

    i am asking about research papers that are relevant with corporate governance 

    Arunima Haldar

    Governance may have positive or negative relation with Debt-equity (usually a proxy to measure leverage) depending on the overarching institutional set up of the country. On the one hand, lenders would be scrutinising the firm on governance so as to ensure return of their principle (Shleifer and Vishny, 1997) ; whereas, equity enables them to be owners/ or rather partners in the business enabling alignment of interest.

       In case of audit committee, the role is to oversee the financial reporting and disclosure process. Further, if the committee is independent, theoretically, their role is further strengthened due to independent or outside view of a third party.As their presence enhances the trust towards the firm; it is expected to have positive relation with governance. However, literature reports mixed results towards having independent directors and performance (economic) of the firm.

  • Reza Sanaei added an answer in Spleen:
    What are the major challenges of making Antibodies?

    I am trying to isolate a specific protein from human serum. Antibodies turn out to be the most promising means for this purpose since they are selective enough to capture the protein of interest. The process of making an antibody includes several steps, starting with injection of the antigen to the animal host, extraction of the spleen and lymphocytes, induction of antibody expression into a cell line by hybrid culture and then retrieval and purification of the antibody. I need to know which part or parts of the process might b challenging?

    Thank you in advance for your advice and recommendations.

  • Jeeshma N P added an answer in Site-Directed Mutagenesis:
    How do i solve my problem if there is no expression of protein after site directed mutagenesis experiments?

    I have done site directed mutagenesis in a 4kb plasmid(pQE31) having gene(500bp) encoding 18kDa protein  using Quick change lightning site directed mutagenesis kit from Agilent. Transformed the PCR product into XL gold competent cells. Everything worked fine, after that i sequenced my DNA and confirmed the mutation at 52nd amino acid position. When I transformed the DNA into my expression strain M15 E coli cells there was no expression of the 18kDa protein. my wild type protein was also expressed in the same cells using 0.4mM IPTG. I have tried different concentrations of IPTG and low temperature. Also I confirmed no other insertion of stop codons within the sequence. Also there is no change in the promoter and other sequences. what may be the problem?

    How to obtain GW band structure in VASP without using LWANNIER90 tag?

    Dear colleagues, I have performed GW calculation in VASP with automatically generated k-points. So I want to perform non-self consistent field with CHGCAR files from our previous calculation. The calculation error occurs in this step. In VASPwiki, they use WANNIER90 to obtain band structure however I can't recompile VASP myself. I want to know how to setup INCAR to obtained band-structure in GW calculation without using LWANNIER90 tag. 

    Thank in advance.
