Q. : Students asked me that "we only study about different forms of energy, one form of energy getting converted to another forms of energy. But no one knows what is energy."
Ans: No answer
Q. Sir Why do we have to call something by the name that a scientists used long back, can't we change it.
Ans: Science or engineering is field of perspective, how one looks at something matters. But everything that you read in a book can be changed. If you wish you can express it in a different manner.
It is the terminology, that we learn, in which people who observed certain phenomenon used to explain a particular concept we follow. Learn. To make world understand what you have to say you have to first make them ready to understand. Otherwise no one would know.

CO2 is used as raw material for chemical syntheses. It paves the opportunity to mitigate the greenhouse gas (GHG) emissions. However, it is not mathematically or logically proved yet that carbon capture benefits the environment in terms of resource efficiency. In my opinion, I believe that the life cycle assesment (LCA) would be the most suitable tool to quantify the resource-based benefits due to carbon based methane (CH4) production and to prove the resource efficacy of carbon capture.
I would like the researchers who read this discussion to provide their own ideas on whether LCA is the most suitable tool to identify the carbon capture resource efficacy or are there any methods better than LCA that can be applied on CO2 based methane production.

I am searching on standard books on secondary WW treatment options such as oxidation ditch and maturation ponds. I would like to know which books do you recommend for students.
I wonder that if I would know the mathematical relationship to find the root propagation of a fibrous rooted coconut tree (Coccus nucifera) or a tap rooted mango tree (Mangifera indica) then I can excavate the entire plant safely and install it in a better place if I need to have a building construction where already a tree was planted. This would be the most sustainable approach considering the human requirements and ecosystem wellbeing.
I have prepared 6 manuscripts related to green roof substrates, 4 of them consist of experimental studies and 2 literature reviews. I have previously submitted some articles for 8 journals. But unfortunately I am continuously getting rejected due to "inappropriate content" for the corresponding journal. Meanwhile, some of the journals have facilitated me article transfer options and still I am getting rejected by those transferred journals with same reason of "inappropriate". I don't want to let my works in vain. Can anybody suggest me some suitable journals with high acceptance rate and have subscription options for publications?
It would be a tremendous help.
Excess of fluoride content in drinking water (more than 1.5mg/L) sourced from inland water bodies causes dental fluorosis and skeletal fluorosis. Although reverse osmosis (RO), electrodialysis, and distillation are available for deflouridating inland water bodies. However am not sure that how effective these methods can be used to deflouridate groundwater. I would like to hear some suggestions on the mechanisms effective at deflouridation of groundwater.

I want to start experiments using sulfate AOPs. In many papers, there is used for example : 1 mM of potassium persulfate. Can ayone help me how to prepare this solution?
I have 100 mL of methylene blue (10 mg/L) solution. I want to add 1 mM of potassium persulfate. Should I add 27 mg of solid potassium persulfate and then fill it up to 100 mL with my methylene blue solution, or can I use 0,1 M potassium persulfate solution and add 1 ml of this solution and then fill it up to 100 mL with methylene blue solution ?
Thanks for answers
I am trying to downscale GCM-(CanCM4) data to bhima basin catchment(finer scale) for projecting future scenarios. Further I have used following variables ta,ua,zg,va(all these @ 925,850,700,200 pressure levels) and pr,psl(total 6 variables). I am attaching image which I got from working on GCM, now considering mid point of these GCM grid points only 2 station lie on periphery(+ mark) for down scaling. Can I downscale these GCM points to the 0.5deg grid points? If yes, how to consider the weights?
I´m trying to get an optimal reservoir operation rule in a multireservoir system where some reservoirs have carryover storage. I had developed an operation model based on Kritski and Menkel´s method and uses generalized Storage - Reliabiliy-Yield relashionship. This model has been tasted and implemented in single reservoirs but not in a multireservoir system. I want to know if there are other carryover storage methods that have been implemented in a multireservoir system.
I wanted to ask that if we have to develop a modelling tool to anticipate the impacts of weather extreme events on the water quality of a lake but the amount of information collected in the field is scarce. What kind of models would be better to use and which are the natural processes we should include in the models. Please guide me briefly if possible.

There is a serious need to improve research in the field of metastatic cancer treatment. Being a non-medical person, but being a researcher (also a son of a cancer warrior, but unfortunately lost the whole game), I am feeling that there is a serious need to float fund in the area of cancer research.
When I used to look back in the past I am not finding any reason of occurance of metastatic pancreatic cancer of my father but he had diagnosed with this health ailment, so there was really any root cause of occurance of cancer. Being a student of Environmental Engineering I know there is a significant impact of environmental pollution for cancer disorder and apart from that some studies also shown food habits may be the reason for this deadliest disease.
So, what needs to be done?
How one can win this war?
My serious and sincere questions to all my fellow researchers in the field of cancer cells research, medical practioners and related areas.
If we will able to find out the main precursor behind this deadliest disease then we should start work on this and we have to design some strategies to reach the ultimate goal of no cancer occurance.
If anyone in this group can contribute some valuable comments then I will able to diversify my knowledge in this areas.
Developing countries are assessing environmental impacts by using environmental impact assessment tools but SEA practice is lacking. What are the root cause for non applying SEA strategically?.
One of the most common methods is to submit the manuscript to an editorial (i.e. Springer, Elsevier, etc.). However, what if you want to publish a thesis in a book/chapter book or if you have a large study with an interesting/different approach? What would be the best alternative?
I would appreciate it if someone could give some options (in English or Spanish), indexes, (perhaps price), and an estimate of waiting times.
In a few reference books of environmental engineering is mentioned that maximum acceptable concentration of nitrate is 10 mg/L as N. What's the meaning of "as N" in this unit of measurement? What's the usage of it?

The West Antarctic Peninsula is one of the fastest warming areas on Earth, with only some areas of the Arctic Circle experiencing faster rising temperatures. However, since Antarctica is a big place, climate change is not having a uniform impact, with some areas experiencing increases in sea ice extent. Yet in others, sea ice is decreasing, with measurable impacts on wildlife. Scientist believes that understanding climate change impacts on Antarctica is a matter of critical importance for the world and for the continent itself.
The effects of global warming in Antarctica may include rising temperatures and increasing snow melt and ice loss. The rising temperature may be causing more icebergs to form by weakening the glaciers, causing more cracks and making ice more likely to break off. As soon as theice falls into the ocean, the ocean rises a little. If all of the Antarctic ice melted,sea levels around the world would rise about 61 meters (200 feet).
Dear researchers, please provide your prestigious opinion on this important matter. Thank you
I am proposing that a hierarchical approach is used where coarse resolution variables are used to run a maxent SDM and delineate a presence/absence map for my species (tropical conifer tree species). After which, the higher-resolution variables derived from the LiDAR data used to generate models within these areas. Can anyone foresee potential problems with this approach? or have any better ideas?
Just read out a paper on C:N ratio of the soils of Sal (Shorea robusta) forest in Terai region of Nepal, in that paper the author has shown the data for organic carbon (C) for all the soil samples is higher than that of the available nitrogen (N), and the content by percentage of both C & N reduces with the depth increment up to 1 meter from the surface layer, contrastingly, the obtained results from the surface soil samples of the forest floors of West Bengal shows that the available nitrogen is higher than that of the organic carbon in each and every samples collected either from the mangroves soils or from the soils of the terrestrial natural forests comprising with the tree lines of Sal, is it normal for the luxuriant occurrences of the Sal forest in two different soil chemical environments?
Mangroves have the ability to absorb up to four times more carbon dioxide by area than upland terrestrial forest ecosystems, carbon dioxide is stored as blue Carbon in the sediment of the mangroves swamps and marshes and green carbon in the soils of the terrestrial forest floors, and that carbon sink forms the carbon pool, but the result obtained from the analysis of the sediment samples of both types of ecosystems doesn't reflect that quantity, the organic carbon of the mangroves swamps ranges from 36 to 69%, whereas, the organic carbon content of the soils of the terrestrial forest ecosystems varies from 16 to 66%, then where and how the extra carbon stored in the mangroves sediments as blue Carbon which is four times more than that of the green carbon of the forest soil?
