  • Why Casuarina plantation does not permit the ground growth?

    In general and from my experience, the Casuarina Plantation does not allow underground plant forms. The exact reason for such observation not address well. I think it may be heavy shadow effect and thick litter layer. I also think that any allelopathic effects???

    If any one know the reason please respond it and possible any literatures or research findings...

  • Which is better for clinician to practice in govermental or private hospital?
    What are the pros and cons of each type of practice?
    Krishnan Umachandran · Professor

    One another option is to work abroad, because of monetary considerations.

    In Uganda, the Medical courses are expensive in terms of tuition and stationery. Privately-sponsored students pay over sh1m per semester for five years, making the courses a no-go area for students from poor families.

    Challenges to the healthcare system in Uganda include lack of drugs and other resources in the hospitals, poor working conditions and high patient loads.

    Compared to practice in the public sector since the private sector pays better. Entry level graduate doctors and pharmacists in the public sector are on salary scale U4 where they earn a gross pay of sh700,000 per month or a net pay of sh500,000 (plus other benefits). In the US, a doctor earns over $100 (about sh170,000) per hour. This translates to sh1.3m per day (eight hours), sh27m for 20 days and sh40m for 30 days.

    What is the experimental and calculated value of the Lamb shift for 6S1/2, 6P1/2 and 6P3/2 levels of cesium?

    Please also send me the relevant paper for lamb shift in alkalis as a whole, if available. Thanks.

    Muhammad Anwar · National Institute of Lasers & Optronics

    Thanks Jonas. I already had these links, but the Tannoji's book does not give this information for alkalis. However, the PRA paper does calculate Lamb shift of ground states nS1/2 of alkalis. For cesium it varies from 381.8147GHz to 702.3957GHz according to my own calculations. Does these sound reasonable?

    1. New Series Active Power Filter for Small Non-Linear Loads Simulation and Experimental Work
    Mohamed Y. Tarnini

    This paper explains the behaviors of the new version f the series active power filter based on high input power factorand low input harmonics. The filter is designed to meet the requirements of voltage-current sourced harmonic loads it is based on a load current estimation of the active power filter sensing the load current. The proposed filters can improve the distortion of a small a non-linear loads power. In
    addition, it can suppress the harmonic current and compensate for the reactive power at the float charge mode The experimental results verify that the proposed filters
    have the expected performance

    UNIVERSITY OF MINHO,Department of Industrial Electronics 4800-058 Guimarães, Portugal  

    This paper presents a transformerless topology of series active power filter with capability to protect sensitive loads against harmonics, sags, swells and unbalances of the power system voltages. The proposed topology is constituted by three isolated H-bridge with a voltage source at the DC side. The series active power filter has been studied with the help of PSIM (Power Simulation software) and simulation results are presented. A laboratory prototype is under development and experimental results are shown

    ABSTRACT Nowadays, the active power filters, APFs, can be used as a practical solution to solve the problems caused by the lack of electric power quality, EPQ. The emerging technology of power-electronic devices and the new developments in digital signal processing, DSP, have made possible its practical use. These power filters can fully compensate the nonlinear loads of electrical power systems: harmonics, reactive power, unbalances, etc. So, they can be called active power line conditioners (APLCs). There are many configurations of APLCs, from shunt and series connection to hybrid passive-active filters. The target is to optimize the design using the advantages of each filter with the different load configurations.......

    4.  Simulation And Performance Investigation Of Series Active Power Filter Using Hysteresis Current Control Method
    by Vikash Anand , Madan Mohan Malviya 


    The simulation study of Hysteresis Current Controlled, three phase series active power filter to improve power quality by compensating harmonics and reactive power required by a non-linear load is presented. The series active filter employs a simple method for the reference compensation voltage based on p-q theory. Classic filters may not have satisfactory performance in fast varying conditions. But auto tuned active power filters give better result for harmonic minimization, reactive power compensation and power factor improvement. This paper has proposed an auto tuned series active filter maintains the THD well within the IEEE-519 standards. The results are found to be quite satisfactory to mitigate harmonic distortion, reactive power compensation and power factor improvement.

  • How do you define viscoelastic material in ABAQUS?
    I'm trying to simulate asphalt layers with Viscoelastic behavior in ABAQUS.
    First of all, we must define a elastic property of asphalt, E and v (Poisson ratio).
    After that must input viscoelastic coefficient of Prony series (g_i and k_i).
    But I seen different expression of Prony series in term of define elastic module.
    Many of them, they define prony series in term of E_infinite like below:
    E(t)=E_inf + SUM ( E_i*e^(-t/tau_i) )
    And E_inf=E0 - SUM(E_i)
    And the additional problem is that the ABAQUS get viscoelastic property in term of dimensionless. It's mean that I must divide the E_i to E(infinite or zero).
    the problem is that the i dont know what number must input. and when i try to calculate E_0 , i see the huge elastic module.
    other question is when i want to compare elastic and viscoelastic material, when i want to define elastic module for elastic behavior, what elastic module must input? E_0 or E_infinite
    Files that attached, is the different expression of prony series and abaqus defining of prony series
    Please guide me

    Depending on your thermal budget, you might also induce stresses that degrade the carrier life-time of your FZ so its performance might decay and degrade it closer to Cz silicon.

  • Paul Dias added an answer in Nitric Oxide Assay:
    Does anyone have a protocol for measuring NO production in endothelial cells using DAF-2?
    Does anyone have a good protocol for measuring NO production in endothelial cells (HUVEC) using DAF-2? (or other adherent cells) I want to visualize it with fluorescence microscopy. I tried once but I could not detect any fluorescence at all. Briefly, I incubated my cells with DAF2 DA 1µM for 1h, washed once, added L-arginine 100µM and incubated for 10 min, and added bradykinin to stimulate NO production. I looked in the microscope after a few min and after 1 hour but saw nothing! I realized I need to optimize my protocol so any suggestions are welcome!

    Paul Dias · Unilever

    You would not see any fluorescence in DAF2 stained cells. The reason this that it cannot be internalised. You need to use DAF2DA or the more stable DAF FM DA. You can optimise the concentration of the dye. ideally it works optimally at 1uM concentration in endothelial cells. In case of macrophage like cell line you need to use 10-40uM concentration.

    DAF2 can be used to measure released NO, however the sensitivity is very low.

    The incubation time is 30 min in plain DMEM, followed by incubation for another 1 hr in plain medium, to convert the dye to its reactive form. You can also use probinsic acid for 15 min to do the same function.

    You need not treat it with L-Arginine, since L-Arginine itself will increase baseline NO levels in endothelial cells..

    It is recommended to starve the cells for atleast 6 hrs before the experiments.

    once you have loaded the cells with the dye. you can treat with L-NAME (negative control) for 30 min at 50-100uM.

    Subsequently you can stimulate your cells with your active (bradykinin/VEGF).

    Its recommended that while determining the stimulation potential of bradykinin, the cells should not be stressed (MMPs gets activated that reduce the stability of bradykinin). you can use sodiumNoNOate as positive control. Atleast in this you should get the clear response.

    Please revert for any more help.

    Good luck


  • Collins Adjei Mensah added an answer in Back:
    Can the reviewer request new additions or amendments to the article before publication?

    After doing all the amendments requested by reviewer, and after sending the article back to the editor. Does the reviewer have the right to request new amendments to the article?

    Collins Adjei Mensah · University of Cape Coast

    I think during the review process both the reviewer and the editor must try their possible best to point out all the necessary corrections the author should do. That is the reason why some time is set aside purposely for the review process.

    However, no one is perfect so if the paper has not been published yet  and there is still an important correction that has to be done, the reviewer can still point it out to the editor. The editor can then take a decision on it to see whether is important for the author to make additional amendments or not. This is because the ultimate aim of any journal is to publish high quality papers to get much recognition and a broad readership base. 

  • Hashem Adnan Kilani added an answer in Web:
    What are the advantages and disadvantages of Webinars (Web-Seminars)?

    Webinar = Web + Seminar and this means a presentation, lecture, or workshop that is transmitted over the Web. Obviously, good communication software and a camera need to be installed for this in order that web-interactive presentations can be effectively made. "Online workshops" are also regularly announced and conducted by some software companies. As of now, many conferences mostly feature physical presentations of speakers (plenary talks and oral presentations) and also virtual presentations using computer communication systems. Recently, Webinars - which include all virtual presentations only - are getting popular. This saves the travel cost, travel time, visa and such issues for international delegates registered for the conference. On the other hand, this completely eliminates research interactions, discussions with group participants, social exchanges, sight-seeing and culture aspects. With the advent of technology and fast internet connections around the world, can Webinars emerge as front-runners in Conferences and can they replace the traditional conferences with direct interactions, social / cultural exchanges, sightseeing, tourism etc? Kindly share your views on this topic! Thanks - Sundar

  • Kamal Kumar added an answer in Scientific Community:
    Is it ethical that articles/reviews are being reviewed for publication by the faculties of the same host University/ Department/ institution?

    It gives an impression of false practice in science beside many others that we all must be aware of. What steps scientific community is taking to avoid it and punish the authors & reviewers who do like this. I hope for a particular topic/subject there must many reviewers outside the host University/ Department/ institution. It seems just like a business for money by publishers and job promotions for authors rather than developing science.
