  • James Demers added an answer in Polysaccharide:
    Is there any reaction to bond Amine (-NH2) groups to Hydroxyl (-OH) groups?

    In our synthesis, the hydroxyl group of a polysaccharide should be attached to an Amine group of another molecule which has two amine groups in both ends of its molecular structure. 

    Is there any mechanism or specified reaction to bond these two functional group together?

    The simplest option is probaby to form a carbamate.  Phosgene, or an equivalent such as triphosgene, can convert ROH to RO(CO)Cl, which will react readily with amino groups.

  • Please, Can anyone state the values of bond energies for homopolar and heteropolar chemical bond of Cd, S, Se, Ge, As, Cu, In and Ir elements?

  • Gandhi Doss Subramaniam added an answer in Drought:
    When and where do we use the term drought and water deficit stress?

    Quite often it is said that if we write studies to understand the drought tolerance of coconut or some other crop it is not correct. Please clarify this.

    Gandhi Doss Subramaniam · Central Sericultural Research & Training Institute, Mysore

    Drought and water deficit stress both are related to the availability of soil moisture to the plant. Both may be called as "soil moisture stress" frequently faced by plants. This will vary according to the soil properties. As previously discussed, under drought situation, plants face inadequate water to drive their physiological functions, leading to leaf senescence  and other changes, while "under irrigated" plants face water deficit stress where enough water is not available for absorption and transport of solutes from soil, leading to growth retardation. Plants developed for deficit irrigated conditions should also have adaptability to nutrient poor environments.

  • Parviz Parvin added an answer in Laser:
    Why we have increase in output power by increasing pump current in diode laser?

    By increasing the pump current in diode laser, we see increasing in output power.

    This relation is linear.

    Why we have this?

    Parviz Parvin · Amirkabir University of Technology

    I do not agree that linearity holds at higher pump currents particularly for high power diode lasers because of thermal loss, non-linearity and saturation effects.

  • John Boswell added an answer in Psychology:
    Who is currently researching the link between Attachment Theory, Substance Abuse, and Loss and Grief?
    I am interested in the link between Substance Abuse, Loss and Grief, and Attachment Theory - and how this can influence the outcome of counselling clients with substance abuse issues.
    John Boswell · Independent Researcher

    Bubba, your approach is interesting. Hopefully a reader or readers of this discussion will be able to participate in the clinical trial you are suggesting. I have never thought of pheromones and addiction. I can understand how pheromones are involved in human (and animal) interaction. Arthur Tomie (he is on RG) has done very interesting work with sign-tracking (see Pavlovian Sign-Tracking Model of Alcohol Abuse) and it would be interesting to get his take on pheromones and sign-tracking. I would be very interested to see where this can go. The behaviourists will be rubbing their hands with glee (or just rubbing their faces!). Who else out there has a thought about this. Thanks Bubba for adding a very interesting angle to this question. Would you say that creating the "safe and secure" environment (Attachment Theory) for the infant (by the primary caregiver - the mother) has got a lot to do with pheromones? Best wishes for 2015, John

  • How many insect orders are there?

    Difference of opinions exist regarding the total number of insect orders. It commonly/generally varies from 29 to 32 based on morphological/molecular/phylogenetic information. However, it is really difficult on the part of a non-specialist to follow the most accepted names of insect orders. I am looking for such a list of names of the orders of insects, which are published by authorities within last 10-12 years and accepted by the most workers.

    Rajendra Singh · Deen Dayal Upadhyaya Gorakhpur University

    In recent classification, there are 30 orders of Insects, which are as follow:

    Protura, Diplura, Collembola, Archeognatha (=Microcoryphia), Thysanura, Odonata, Ephemeroptera, Grylloblattodea, Plecoptera, Embioptera, Phasmida, Orthoptera, Blattodea, Mantodea, Dermaptera, Isoptera, Zoraptera, Psocoptera, Phthiraptera, Thysanoptera, Hemiptera, Strepsiptera, Neuroptera, Mecoptera, Coleoptera, Diptera, Siphonaptera, Trichoptera, Hymenoptera, Lepidoptera

  • Matthew Huxter added an answer in Mood:
    What door colors are best to use in an ED room for psychiatric/mental health?

    I have read studies that discuss mood and color in psychiatric settings, but often the study is of a person and the color which does not take into account the many other variables experienced by someone in the emergency department.  There are studies of other rooms, such as used during therapy or in the general milieu.

    I'm looking specifically for door color since our rooms are and will always be laboratory white.  I'm thinking that a great study would be to have at least two rooms with different colored doors and see which one the person (in acute psychiatric distress) chooses indicating a perception of safety.

    Matthew Huxter · Flinders University

    That is an excellent question, as it is well understood by clinicians and patients themselves that the ED environment in itself is not conducive to promoting recovery for mental health patients, largely due to its high stimulus and sensory input nature. In Australia long wait times for ward beds are generally becoming the norm, and patients can be left for days in the ED, and ward environments (especially PICU's) are ideally designed for calming environments (though unfortunately this is not always the outcome) , so one would think that colour selection would also play a role in that. I saw a documentary about a Swedish mental health hospital designed for eating disorder patients that found a link with improved outcomes for their patients when they were in highly controlled environments that consisted of soft lighting, room temperature modulation around 26 degrees celsius, and soft colours within their accommodated rooms.

  • Dr bablu Ghosh added an answer in Hall effect:
    What is the purpose of a bridge circuit in a setup for high resistivity Hall effect measurements?

    For standard measurements where the sample resistance is <1 Mohm, no bridge circuit is used, but in our setup, for samples with sample resistance >1 MOhm, a 1K bridge circuit is used.  

    Just wondering how the measurements will be affected if the bridge is not used.

    Thanks for any input!

    Dr bablu Ghosh · Universiti Malaysia Sabah (UMS)

    Actually hall effect is measured of a sample has 3D configuration. The concept is elector-gagnetoststics as current,I perpendicular to magnetic field,H and develop voltage due to charge accumulation for the  magnetic effect as V  3rd coordinate. But for  the accurate measurement, all other direction of flow current and its consequence as developing voltage, v need to be consider. Thus it is measured in such bridge way.

  • How can I differentiate large size plasmids from genomic DNA ?

    I have a wild type bacteria culture and want to check the presence of plasmids in it. I followed the normal plasmid isolation procedure and got a small pellet. In gel electrophoresis a lower intensity band also visualized. The problem is its size is similar to the genomic DNA when they run parallay on the same gel. Gel was 0.7% agarose gel in 0.5x TBE buffer. I did restriction digestion with Not1, BamH1, Hind111. but could not resolve visualize clear bands on the gel. 

    Santanu Sasidharan · Bannari Amman Institute of Technology

    I think that your plasmid DNA is contaminated with your genomic DNA. I suggest that you redo the procedure for plasmid extraction and be careful at the alkaline lysis step as this is very critical. I also suggest that you increase the agarose concentration to 1% for better separation.

  • Long Pham added an answer in Stem Cell Isolation:
    Mesenchymal stem cell isolation from rats: what are the differences between old and young rats?

    I am doing the mesenchymal stem cell isolation from rats. I wonder whether there are differences between cells extracted from neonatal rats and from those from older rats.

  • Barbara Sawicka added an answer in Reality:
    Do great scientists communicate with the real world successfully?

    Many scientists are truly occupied with their researches, experiments and studies. Considering often remarkable ideas in depth, some of them have built their own realities. Hence, are they capable of communicating with society successfully?   

    Barbara Sawicka · University of Life Sciences in Lublin

    Researchers often overlook his role, becoming politicians and preachers, even mention of the past and of the present Lysenko Dawkins. In large part this is not just their fault, but most of wsystkim different backgrounds that add themselves to the standards authority typing scientists. Each of us has the right to speak in a variety of topics. But it does not always speaks as a scientist. Often contrary to the intentions and against the will exists outside their specialty, as an expert in everything.

  • Is there any waste material from industry that can improve engineering properties and reduce swell-shrink behavior of expansive soil by stabilization?

    In expansive soil there's a problem regarding unstable engineering properties due to varying moisture content and also it shows dramatic changes in swell-shrink behavior for the same. I have already used two waste materials marble powder and brick dust for the solution of this problem and both gives successive results for improving properties and minimize the swell- shrink properties. I want to know is there any another waste material from industry that can give me the same result to reduce the swell-shrink properties of Expansive soil.

  • Why some time after DNA extraction there is no band in electrophoresis?

    I extracted DNA from bacteria by using extraction Kit, by when I run the DNA on agarose gel no DNA band detected, but when I did the PCR reaction I got good result. And when I run it on agarose gel I got good bands?

    Mushtaq Talib shawi AL- Rubaye · Shahid Beheshti University

    thank you nilmini

     but i do not understand "but be careful not to contaminate yourself and the lab environmnt from your amplicone which result contamination in your next pcr. therefore do a negative or control pcr along with your pcr.if control sample contain same size band u cannot conclude that u have amplify the exact gene u want."

    when I do PCR with 2 primers for 1 gene Even in more than 1 bacteria all products wil be same size.

  • Ali Abdil Razzaq Muhammed Noori Aldallal added an answer in Hyperlipidemic Model:
    Does any one experience with ideal diet induced hyperlipidemic animal model?

    We need to test our herbal drug with diet induced hyperlipidemic animal model (Sprague Dawley rats) and we have gone through literature to know about high fat diet. There are many protocols to induce hyperlipidemic state, which involves cholesterol, cholic acid, and coconut oil, or lard. However, when we drying, the rats are not eating the food, that was made from coconut or lard?. 

    If any one experience with successful protocol to induce hyperlipidemia, please share with us.
