How to manage higher total soluble salt water for irrigation?
Water management or Agronomist, Soil scientist
it is possible to manage total soluble salt water content for irrigation by using either drainage water which contains high salinity levels or prepare different levels of NaCl in mM concentrations. In both cases, it is necessary to use tanks for the storage of such high salinity irrigation water.To get the best result, drip irrigation system is the best. The level of salinity used,of course, depends on plant species. The levels of salinity in the tanks must be checked regularly.Following

Can a native plant species be referred to as Invasive?
In some cases, a species native in a given region can exhibit rapid growth and biomass accumulation, high reproductive output, phenotypic plasticity, plasticity of reproductive strategies and many other characteristics of invasive alien species.
An example is Digitaria abyssinica, a plant native in tropics, but a very noxious weed as it forms dense mats of grass that suffocate co-occurring species. Also a a problem for agriculturalists in Africa. When i checked some invasive plant databases, i found it was not listed as invasive.
Does that mean we only classify plants that are alien to a given geographical range as invasive?
According to the standard definition, an invasive species is a plant/animal which is not native to that specific location. Invasive species are mostly alien species and have been introduced into that eco-region from other places and have a very high growth and reproductive ability. Thereby, such species have a high tendency to spread, often at the expense of native species; and may cause multi-fold damage to the environmental and socio-ecological system.
Often, even native species exhibit many 'characteristics' of invasive species, such as rapid growth and reproduction; and may often out-compete other native species, stunting their growth. In such a scenario, such native species are generally regarded as pest or weed species.

How to annotate the nucleotide sequences in terms of KEGG Orthology (KO)?
I have a RNA-Seq data in which I have to construct the KEGG Pathway for DGE between two samples. I also have nucleotide sequences (contigs) in the fasta format (.fa) file. Kindly tell me how to assign the KO IDs to these nucleotide sequences. Also help me in construction of pathways either using KEGG, Cytoscape or any other pathway network builder software/server.
The best way is to use Galant plugin in Cytoscape which solves the purpose that you aim for. Please make sure that the ids are obtained from nuc sequences using NCBI's batch entrez before you construct the pathway networks.
Hope this helps
Apart from the "traditional" three dimensions of sustainable development (environment, economy, society), what other classifications can be used?
Are 3 or 4 pillars enough or should they be discarded completely? The CSD have abandoned the three dimensions and opted for using cross-cutting themes instead. Is there any other evidence to suggest this is a better way to go?
In my opinion, we have to differetiate between an analytic approach in scientific work. In the latter context, we should keep focusing on the classic three dimensions. CSD is not a scientific but a political institution. In this context it may sometimes be meaningful to leave the clearly structured path. However, I cannot identify any benefit arising from the cross-cutting approach.Following

Should a lesgislation be enacted by US congress to ban the use of drones for combat and reconniassance mission?
Drones are very dangerous instruments aimed to kill its intended target on the spot. However on many occasions this has not been the case, instead reports have been given of more deaths and casualties of innocent civilians that have become victims of drone strikes then terrorists being killed. According to an analysis carried out by the human rights group, the US drone strike that was intended to target a number of 41 men killed 1,147 people, who were innocent victims in Pakistan.Following

Is there an R package for multivariate distribution for missing data using maximum likelihood estimation?
I'm currently anaysing the missing data problem using maximum likelihood estimation.
I would like to test the estimation on missing data for multivariate dataset using R. I found several packages in R for MLE but some of them are only discussing and applying the general function/term/concept to apply MLE but do not specifically applying on the missing data problem for multivariate dataset.
My current dataset is having the combination of categorical,continuous and discrete data types
I would appreciate if someone could recommend me the notes or tutorial for applying missing data using MLE in R
Thank you in advance
Treatment of missing data in Structural equation models (SEM) or linear regression models can be done by Full Information Maximum Likelihood (FIML) estimation. Given missing completly at random or missing at random this leads to unbiased estimations. The package "lavaan" is, to my knowledge, the most complex SEM package for R. It offers the option to fit models by FIML.
But be aware that FIML is only applicable for models with continious outcomes. If you have categorical outcomes or mediators in your model it will not work.
For these conditions multiple imputation methods are the best solution. There will surely exist R packages on these too.
If your study question may be handeled by propensity score analysis, there also other methods that can be used.Following
What New Media do you use in teaching at the University?
It is said, that New Media transform and revolutionize modern teaching as they improve transmission and distribution of information and knowledge. If it is truth, we should use them.
I am wondering... to what extend and in which form does New Media are used at the University ???
Hi! I used Web 2.0 or Social Web in class. We use Twitter to share news that go with the topics discussed in class. We also use wikis and forums to to engage students in the collective work . I consider very important to involve each student in the overall group learning and these tools are very helpfull. I have published a paper about that topic and currently I am researching on that question in my university (comparing the use of social media in the different Faculties).

Toxicity testing of soluble components from soils.... Metals can promote cell proliferation?
Hi to all,
I have performed an HepG2 cell proliferation assay on 14 soil samples from two sites in the north of Italy. I have exposed cells to water soluble extracts of soil (soil suspension in water (soil water ratio 1:4 w/v ), sonicated for 1 hour, deposited for 24 h and sonicated for 1 h... centrifuged and liophilized).
After 24h and 72 hours of exposure I have recorded a proliferative effects in most o f the samples. Cells are more than 120% respetc to their control (untreated). In some sample the stimulation effect is present at low dose, in other samples the effects are present in all the tested doses.
Someone have articles or works that I can cite about this proliferative effects?
Are metals able to promote proliferation?
What compound can be responsible of these effects?
I have hypothesized that there are some phytoormones which can promote proliferation... I think that these compounds are not estradiol-like compounds because HepG2 do not express ER receptors.
Please help me!Following

How thick should Ti adhesion layer be?
Making 100 nm wide nanowires to break controllably using electromigration, see DR Strachan et al. for example.
Previously I've used 2 nm Ti adhesion layer and 14 nm Au; I use ebeam evaporation to deposit the metals in vacuum, into a PMMA negative from EBL. I am concerned however that a 2 nm film of Ti is not continuous, and that 4 nm would be safer.
I am wary of going too thick however, as when the gap breaks via electromigration, I try to trap a molecule in the gap, connecting two Au electrodes. the Ti can be problematic for two reasons:
- If the exposed Ti, which is presumably not oxidized because it was protected by the Au, does not also electromigrate then it will short the ends. Some recent work suggests that Ti can electromigrate however so it is possible that it would do so.
- If the Ti does electromigrate, a Ti-Ti tunnel junction would not likely contain the molecule (I use thiolated molecules to form self-assembled monolayers on the Au).
Previous work, my favorite of which is from Takhee Lee et al. has used 1-2 nm of Ti or Cr, so I am further hesitant to go thicker. It is difficult to test this matter as well.
Thanks in advance for any advice.
I had similar problem when I fabricated OTFT with a short channel. Only in my case the gap between the Gold electrodes is much wider (~50nm) and I don’t produce it via electromigration.
Eventually I used Cr as adhesion layer, and after producing the gap I used a short step of Cr etch to remove the Cr from the gap. It couldn’t work with Ti since our Ti etcher contain HF so it attacks the SiO2Following

After how much time can we infect the cells with Lentivirus?
Hi everyone. I prepared the Jurkat cells for transduction i.e by adding polybrene, IL-2 and RPMI with 10% FBS, I want to know that after this, if somehow i could not add the virus immediately, and i add it after 2 hrs, does it affect the transduction process?
You may also try protamine sulphate instead of polybrene. Slightly less efficient, but much less toxic and you can use higher concentrations and times of infection. And, I agree with Mikhail, spinoculation works better, both with suspension and adherent cells.Following
How can we have rectangular-shape aeolian erosion?
I observed rectangular-shape aeolian erosion in the coastal area of South China, as shown in the attached picture, very regular pattern and spectacular. We know this kind of caves/holes are usually caused by wind or water force during the erosion. But how can we have such a neat distribution of rectangular holes? Does it mean that during the erosion, the wind was always blowing from one direction that is perpendicular to the outcrop?
I don't know if the permafrost can be involved. The field location is at the southern most part of China, with a latitude of about 22 N, where the temperature seldom decreases to 0 degree. According to the plate reconstructions, the South China Block has been always moving around the equator since Devonian. But I'm not sure about the global temperature in the past...
What kind of evidence can we observe in the field if the permafrost is involved?
