Dear all,
I have submitted my research article to Environment, Development and Sustainability (Springer) 3 weeks ago. It took five days for getting the "Editor assigned" status after my submission and still it remains as same for more than 2 weeks. The article has not yet been sent for review yet.
Could anybody suggest me that,
1) Is it a normal case of being in "Editor Assigned" status for more than 2 weeks?
2) how long it takes in Springer journals for an article to be sent for review?
I would like to welcome your responses.
Relevant answer
Answer
Hello, again, Shuraik Kader (it has been a long time since you heard from me)
I agree with Rob Keller that this length of time is very long. And, unfortunately, it is longer in some journals than others. That variation depends on the journal (how long it takes for the editor and the staff - what they are like) and depends a bit on your article (if it is a topic that it is very hard to find reviewers for). My advice is to be patient - we authors always want the results faster… If you are bored with waiting I suggest you can start work on your next project/paper…!

Circular Economy and Triple Bottom line are two main tools in achieving sustainable development goals. But many academics, professionals and stakeholders are finding difficult to distinguish the difference between them and also fail to interconnect them. In this aspect, how they are inter related in terms of construction industry and technological applications?
Relevant answer
Answer
The Built Environment sector consumes a substantial portion of non‐renewable energy and prompts the emission of a significant amount of CO2; contributing approximately 39% of the annual global CO2. A third of the usage of total energy and CO2 emissions is a result of the Construction Sector in the developed and developing nations.
The Smartcrusher is a classic example of Circular economy by Netherlands Circular, 2018. Concrete is strong enough to last for centuries. But every kilogram of cement produces one kilogram of CO2 emissions. This means that today’s concrete and cement industry emits about three times as much CO2 as all aircraft combined. Crushed pieces of concrete can now only be used as low-grade gravel replacements. SmartCrusher is a device that separates the unused cement stone from the concrete rubble. It also produces residual flows of good quality sand and gravel. The cement stone can be used directly in concrete production and thus saves cement and CO2 emissions. With SmartCrusher, 50% of the world’s largest concrete construction flow can be made circular. The revenue model shows that the investment can be recouped within 1.5 years and that the price of concrete is halved. And that without including CO2 pricing
In the category of PROFIT, the price of concrete is halved, allowing more headroom for profit. There is ample savings from less waste and Carbon Tax.
In the category PLANET, the impact of CO2 emissions is the rise in global temperatures that result in shrinking changes of water supplies, changes in weather patterns and increase in sea levels; among others. By reducing emissions these consequences of global warming are curbed.
PEOPLE are better off with less CO2 emissions. Air pollution from construction has a direct effect on construction workers’ health, and the health of citizens near construction sites. As an example, the UK’s Health and Safety Executive has found that over 200 construction workers die yearly prematurely from diseases caused by exposure to diesel fumes (Bellona, 2019). There is no safe amount of air pollution, which means that the less air pollution we can have, the safer it will be for construction workers, and citizens exposed to construction sites.
*The triple bottom line is a business concept that posits firms should commit to measuring their social and environmental impact—in addition to their financial performance—rather than solely focusing on generating profit, or the standard “bottom line.” It can be broken down into “three Ps”: profit, people, and the planet
*A circular economy is "a model of production and consumption, which involves sharing, leasing, reusing, repairing, refurbishing and recycling existing materials and products as long as possible."

Thermal mass is a property of construction materials to absorb, store, and release heat energy. It is an important element of passive solar house design and can be utilized for passive solar heating, passive solar cooling, or both. I would like to know, what is the most effective technique to quantify these kinds of thermal masses in an existing construction?
Relevant answer
Answer
The simple muiltiplication of the mass by the thermal capacity as Bachir Achour proposes, is valid only at thermal equilibrium. Since buildings are always in a thermally dynamic state, this method strongly overestimente the active thermla capacity. When the ambient temperature continuously changes, the calculation is more complex, and needs solving the equation of heat. Simple mathematical solutions to determine the thermal mass of a multilayer plane building component under dynamic conditions are indeed described in EN-ISO 13786 as mentioned by Edwin Rodriguez-Ubinas.
An experimental method to determine the dynamic thermal capacity of a room was proposed by Van der Maas (see attched paper). The apparent room effusivity can be measured by recording the increase of the indoor temperature after switching on a constant power heat source.

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.
Relevant answer
Answer
"Life cycle assesment (LCA)" could be jointly addressed with the "circular economy (CE)" and the "ecosystem service valuation (ESV)", as an integrated tool to "quantify the resource-based benefits due to carbon based methane (CH4) production". Besides, this integrated approach can better control the excessive use of material, lowering the energy needs for new products, saving natural sources from overexploitation and environmental degradation, managing labour's capital, and proving the resource efficacy of carbon capture.

Hello Ahmed .
Top 12 Best Open Source Software in Water Resources are listed below:
1. QGIS
QGIS is the most popular GIS tool with an impressive trajectory and a vibrant community. It also even has a particular ecosystem of complements called “plugins”. QGIS is a completely open source alternative that reduces the cost barriers since it does not need a paid license and can be executed in any operative system.
2. SAGA GIS
SAGA GIS is a GIS platform oriented to spatial analysis. SAGA GIS is a simple but powerful tool, with a big library focused on spatial analysis and characterization of basins. The interpolation options in SAGA GIS are better implemented than in other free and commercial software.
3. HEC-RAS
The numerical model HEC-RAS is developed by the U.S. Army Corps of Engineers. This model uses the gradient and topography to evaluate the flow depth, velocities and flooded zones. It is also useful to calculate sediment transport and water temperature.
4. iRIC
iRIC (International River Interface Cooperative) is a software developed with the purpose of offering a complete simulation environment of the riverbed and its results can be exported and used to analyze, mitigate and prevent disasters, through the visualization of the results of the river simulation.
  • Hydrologic modeling
5. HEC-HMS
The Hydrologic Modeling System (HEC-HMS) is designed to simulate the hydrologic processes in basins. The software includes traditional procedures of hydrologic analysis, such as infiltration events, unit hydrograms and routing. HEC-HMS also includes modules for evapotranspiration, snow melting and calculus of soil humidity.
6. PRMS
The modeling code PRMS (Precipitation Runoff Modeling System) is a modular system of spatially distributed parameters, which represent the physical processes of a basin. It was developed by the United States Geological Survey (USGS) to evaluate the effects of several combinations of geomorphology, type of soil, soil use, vegetation and climatic parameters in the hydrological response of a basin.
7. SWAT
SWAT is a tool to evaluate soil and water at a basin scale. It is focused in precipitation-runoff modeling and transport of water and solutes through surface flow. It predicts the impacts of soil management practices in water resources and sediments
  • Hydrogeological modeling
8. MODFLOW
This code performs groundwater modeling based on finite differences developed by the United States Geological Survey (USGS). It is capable of simulating groundwater 2D and 3D flux and simulate the principal physical processes related to the groundwater regime such as recharge, evapotranspiration, pumping, drainage, etc.
9. MT3DMS
The MT3DMS package is a mass transport model coupled to a flux model in MODFLOW. The MT3DMS code simulates advection, dispersion/diffusion and chemical reactions of adsorption/absorption of contaminants in groundwater.
  • Computational fluid dynamics modeling
10. OpenFOAM
Pretty much any physical phenomenon associated to fluid dynamics can be represented with this software. The amount of packages incorporated and also its condition of an open source code make it useful to explore the possibilities of modeling several types of problems including the addition of a reactive model.
11. Python
This is the favorite code for scientific, water resources and environment analysis. It has several packages for different tools such as GIS, mathematical analysis and artificial intelligence.
If a complete tool for manipulation, processing and plotting of data is needed, Python – Scipy is an effective, versatile and free code solution.
12. R
R is a programming language for statistic calculations and graphics generation. It is easy to understand and makes it possible to make complicated analysis with just a few lines of code.
It is the best option to perform spatial analysis since it incorporates several interpolation options.

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.

Answer
Hello Mr. Hajipour
"N" refers to a molecular nitrogen presents in a defined concentration of a molecule or ion. You can find it out by multiplying the molecular weight ratios.
In your example if N in the form of nitrate (NO3^-) is 10 mg, then the concentration of nitrate molecule will be 10 mg N*(62 mgNO3/mmolN)/(14 mgN/mmolN), i.e. 44.28 mg NO3^-.
Same concept is valid for any other atoms and molecules.

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
Relevant answer
Answer
The most significant impact is obviously, the rise in existing sea levels and flooding of the coastal regions. This will lead to loss of life and property and will force millions of people to migrate from existing land to some other areas. This mass migration may lead to clashes between people even lead to disturbed political situations.
How to stop this, is the real situation on which researchers are still working in different fields (for ex. CCR & CCU). However, in my opinion, the solution to control global warming can be solved, if man is willing. Since there are a lot of economic constraints, and the world economy and existing machines and infrastructure can work on fossil fuel as a source of energy (to a major extent). Hence it will take time to switch to green and renewable sources of energy. Again here, the economy and availability of technology will be a major constraint, and the balance (i.e. the consequences) will shift again to the side to which process is fast (i.e. rate of global warming rise vs rate of switching to renewable sources of energy).
The easiest way to control global warming is still, planting more trees to maintain and control the world's CO2 levels.

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?
Relevant answer
Answer
Interesting idea. I have no clear yes or no for you.
However, I see one potential problem. Using MaxEnt, we want it to learn for itself whether variables are predictors or not.
So by forcing climate variables as the primary cutt-off of presence/absence, and then running the "final models" only within "suitable climate" areas, you basically disable maxents ability to decide for itself.
Also, potential areas outside the "suitable climate model", which could however be presence if climate is not a super factor, will be missed completly.
One last point to keep in mind: climate variables are generally often correlated with other topographic and/or landcover data.
So you might be overrepresenting some factors if they are represented by climate first and by other variables in your second model secondly.
However, if the root of your problem is the climate variables being to coarse, then you might just work around by using a dem instead of the climate variables (given there is a strong physical causality from elevation to temperature)?

Answer
Mr.Muneeb,
I feel the main important one in all over the world is population increase and no space available for developing infrastructure relative to increase in population. so the construction activities have taken place as closer to an existing structure. In view of this, the stability analysis of existing structure adjacent to new construction in terms of excavation, embankment, tunneling or pile driving is a serious problem. As a geotechnical engineer we need to come out with design idea to protect the existing structure due to the effect of new construction.
Another important issue is we don't have excellent supporting ground for the new construction. So, in this case we need to develop economical ground improvement technique to support the load. Ground improvement technique alternate to conventional method is catching up among researcher . ok all the best in your research..

Are these formulas correct for the conversion?

2. metal (mg/kg) = mg/L * final volume (ml) / initial sample weight (g)
Relevant answer
Answer
I am going to explain you the situation by a numerical example :
Think that you have digested 2.5 g of soil sample in 25 ml acid and after digestion you got only 1 ml aliquot from this digested solution and diluted it into 100 mL. So your final volume became 100 mL. Imagine you measured Cd metal in this 100 ml solution and the instrument gave you result as 0.53 mg Cd/L.
mg Cd/kg = ( 0.53 mg/L * (100 ml/1ml) * 0.025 L ) / 0.0025 kg
100 ml = final volume which you test by instrument
1 ml= aliquot taken from the digested sample before any dilution (if you take all the digested part you must write 25 ml instead of 1)
0.025 L= total volume after digestion in L (=25 mL)
0.0025 kg = sample weight in kg (=2.5 g)
I hope it is clear enough and help you and all other colleques :)
Good Luck everybody in their research!

OPC is the 2nd largest generator of CO2 after automobile industries. Researchers have claimed that geopolymer based concrete is more stronger , durable,versatile and eco friendly but unfortunately it has not been widely utilized in practice. I wanted to know its limitations and if there is any possible health hazards related to it. I have also heard that it has some sorts of toxic effects. Is it just a hoax?
Relevant answer
Answer
The term "geopolymer" is widely used for slag cements and alkali-activated (slag) cements, too. The production and handling of those systems (without any Ordinary Portland Cement OPC) are neither "difficult to create", have not to be "premixed only" nor "sensitive" at all. Major and fundamental research work and applications have been performed in Russia, China, Ukrania, Japan, India, Spain, Germany and Tschechia since 1990. Intense research about this very competitive product to OPC has been done and patented by P. Krivenko, F. Skvara and J. Gebauer& L. Ko{HOLCIM} and other international cement producers.
Most important is a constant quality of the components for geopolymers:
- Homogenous slags or ashes of consistent/constant quality with high glassy phases
- Proper adjustment of desired slag/ash with alkali source (Sodium or Lithium Sulfate, Sodium Silicates( "water glass"), Sodium Metasilicate, Alkali Hydroxides, Calcium Oxide and/or Hydroxide etc.
Since the constant quality of slag/ash component is necessary, geopolymer production is especially economically in those countries with/or close to a strong heavy metal industry. Geopolymers have a much improved ecological balance (less Carbon Dioxide and dust emissions compared to OPC), very good to excellent compressive strength and much better chemical resistance/durability in comparison to OPC.
The major draw-backs of geopolymers are the lack of standardisation, the strong lobby of the OPC producers....and the still lax legislation on CO2 reduction...but the time for geopolymers will come!

- Harm water quality and temperature.
- Block fish migration
- ...
Relevant answer
Answer
From the previous answers, a lot has been said regarding the potentials usefulness of dams, which is really good. I would like to adress in this answer, for the sake of discussion, some key points regarding why dams can be problematic to us.
It appears that during the past decades, wild river streams (ones that run free from headwaters to confluence) have nearly been wiped and then replaced by river dams. Fact is, dams disrupt natural systems and subsequently thwart the work of rivers. They block fish runs, seasonal flood patterns, affecting redistribution of nutrients (like marine nitrogen delivered by salmon to feed the inlands).
Dams encourage unsustainable growth, displace people, often indigenous people
Very often, dams are built through grants of institutions and rarely benefit the local people. Most of the generated hydropower (if any) is delivered to big cities, not the rural villages displaced by the dams.
Even from a design perspective, it appears dams are made to fail. A huge reservoir surfaces mean terrible annual evaporation losses. Silting is unavoidable. Even the largest reservoirs silt up. When they collapse, it is nightmarish.
Some researchers point out dams are not the solution to our energy crisis. Solar and wind can provide far more reliable, long-term energy than hydropower with far fewer environmental costs.

What are the factors for selecting a suitable location for installing waste stabilization ponds facilities ?
Relevant answer
Answer
Well,
Factors to consider when determining the public location of a wastewater treatment plant are:
- Location of the inlet to the facility.
- The location of the treatment units should be suitable for the work of the wastewater collection system according to the topography of the earth. It is preferable that the sewage flow into the site by the natural slope of the drainage and thus the pumping station can be dispensed with.
- The location of sewage treatment plants should be relatively high for the rest of the land to protect them from rain and floods.
- Hydraulic position of the facility - a straight flow path between the units is recommended to minimize loss of load and to ensure equal consistency of flow separation.
- The treatment plants should be sufficiently far away from the city and the network service. There should be a buffer zone between the site and the residential areas. These buffer zones should preferably be green spaces that will enable the access of the personnel responsible for the operation to each point of the treatment unit.
 - The location of the station should not be chosen so that foul or distinctive odors can be transmitted to the city or neighboring population group based on the study of wind and climate trends.
 - The location of the treatment plants should be close to the electrical sources necessary for operation.
 - The location of the treatment plant shall not interfere with the urban plan of the city and its future expansions, nor shall it interfere with the laws of the protection of agricultural lands.
 - The location of the treatment plants shall not interfere with the planning of future expansion areas needed by the city and shall permit the extension of the future wastewater collection network.
- The selection of the site should be sufficient for the current work and future expansion for a period of at least 50 years. The site should be considered in the design of the general plan of the station so that the area of ​​the treatment units is not less than 75% of the total area. Before selecting sites that require the purchase of land, taking into account that the high-priced locations or that have legal problems in terms of purchase, ownership and the like are not chosen.
- Try to take advantage of state-owned sites first
- The location of the treatment units should be the nearest agricultural land or can be cultivated or the surplus can be used for irrigation and the use of the liquid and dried sludge produced by using it as fertilizer.
 - The location of the treatment units should preferably be near the valleys or natural flood streams.
- Attention to the aesthetics of the station for the workers and staff at the station.
- Control of the station and attention to environmental protection.
 - Economic operation.
- Existence of transport outlets.
- The location of the final discharge point is close to the station and does not cause trouble for neighboring areas.
- Preliminary information for the study in order to identify the necessary treatment.
