Are there some examples of Carbonatites found outside Continental areas, i.e, Island Arcs and/or Oceanic Crusts origin ?? In this case, can these resources hold Li, REE, LREE and related ? Photos and documentation will be welcome too. Thanks a lot colleagues.
Relevant answer
Answer
you can deploy Copilot Let's dive deeper into the fascinating world of carbonatites, especially those found outside continental areas, and explore their potential for containing valuable resources like lithium (Li), rare earth elements (REEs), and light rare earth elements (LREEs).
### Carbonatites in Oceanic Settings
While carbonatites are predominantly found in continental settings, there are notable examples in oceanic environments, particularly in oceanic hotspots and island arcs. Here are some key examples:
1. **Cape Verde and Canary Islands**: These are prime examples of oceanic hotspots where carbonatites have been identified. The carbonatites in these regions are formed due to the low silica and high alkali content of their primitive melts.
2. **Fogo Island (Cape Verde)**: The carbonatites here are coarse-grained Ca-carbonatites (sövite), while on Santiago and Maio islands, Mg-carbonatites are also present.
3. **Fuerteventura (Canary Islands)**: This location provides new insights into the geochemical characteristics of oceanic carbonatites, showing similarities with those from Cape Verde.
### Resource Potential of Carbonatites
Carbonatites are significant sources of various valuable elements, including REEs, LREEs, and lithium. Here’s a closer look at their resource potential:
- **Rare Earth Elements (REEs)**: Carbonatites are one of the primary sources of REEs, which include elements like lanthanum, cerium, praseodymium, and neodymium. These elements are crucial for various high-tech applications, including electric car motors, lithium-ion batteries, and magnets.
- **Lithium (Li)**: While not as commonly associated with carbonatites as REEs, lithium can still be found in some carbonatite deposits. The extraction of lithium from these deposits can be economically viable due to the high concentrations of other valuable elements present.
- **Other Elements**: Carbonatites can also contain significant amounts of niobium, zirconium, and phosphate, making them valuable for multiple industrial applications.

Hi Folks,
There happens to be a small island in Red Sea, KSA, a portion of which is inhabited by a good number of Red Sea Ghost Crabs (Ocypode Saratan). In the coming months, there is expected to be a jetty coming up in that patch of the island. Considering the near-endemism of these crabs, is there a protocol which can be adopted to carry on with the construction of the jetty without disturbing the crab population? There are other similar patches in the island, but with rocky barriers between them.
Also I would like to know if there is any translocation protocol available?
Thanking in anticipation!!

Answer
Sandy beaches make up approximately three-quarters of the world’s shorelines. They are important ecosystems, hosting abundant invertebrate macrofaunal communities that provide food resource for vertebrate predators such as shorebirds, seabirds, marine mammals and fish. Although possessing a terrestrial appearance, food input on sandy beaches is derived predominantly from the sea. Such food input includes detrital matter, mostly in the form of wrack, and has the potential to support a great diversity of species, as well as stabilising energy fluxes and dynamics of consumer populations. The movement of detritus, along with other vectors such as organisms and nutrients, across ecosystem boundaries can alter productivity and change consumers’ distribution, abundance, and growth rates at multiple trophic levels in recipient systems. Ultimately, the input of nutrients and detritus can increase primary and secondary production and alter food web structures and community dynamics in recipient ecosystems, a process termed “spatial subsidy”.
Ghost crabs (Ocypode spp.) form an important component within beach communities in several places around the world and are part of this trophic complexity. However, little is known of their densities, trophic structure and the role they play as vectors for spatial subsidies through movement of marine derived nutrients inland.

We are writing an essay on climate change and its impact on indigenous people circumpolar north people, native nations, islandic, aborigenal of pacific and so on
Relevant answer
Answer
Local and indigenous perspectives on climate anxiety offer unique, culturally embedded understandings distinct from Western definitions. Among the Inuit in the Arctic, the concept of "sila" refers to weather, climate, and the broader environment, reflecting a deep interconnectedness. Climate anxiety here stems from changes in ice and animal migration, impacting traditional lifestyles and spiritual practices.
In Australian Aboriginal communities, "Country" encompasses land, water, sky, and all living beings, integral to their cultural and spiritual identity. Climate anxiety arises from the degradation of "Country," disrupting cultural practices and ancestral knowledge.
Pacific Islanders face existential threats from rising sea levels, with the Fijian concept of "vanua" linking land, people, and identity. The loss of "vanua" is both a physical and cultural crisis.
Amazonian Indigenous peoples experience climate anxiety through deforestation, which threatens their survival, cultural practices, and spiritual beliefs. The forest is not merely a resource but a spiritual entity, with its destruction leading to profound anxiety.
These perspectives highlight that, for many indigenous communities, climate anxiety is deeply tied to cultural, spiritual, and communal dimensions, illustrating a holistic connection between people and their environment.

Answer
Likely you're using a Raman microscope for your measurements. Try to use the lowest magnification objective, this should increase the spot size.
(In the limiting case, you could try to completely remove the objective (just unscrew it) and excite the sample with the unfocused beam. Though the collected signal could become very small in this case.)

Hi all,
I am new to computational field. currently, am working in protein-protein interaction. Is it necessary that we have to apply forcefield before docking and once i am applying forcefield, i am seeing the following error,
After navigating to the simulation tab, I proceeded to choose the Forcefield option. Then, I clicked on Charmm27 and applied the selected forcefield.

Assignment of force field parameters is essential step in any molecular modelling calculations. All the calculations are carried out using these parameters. From the error, it looks like that parameters/topology file for the indicated residues are in not available in CHARMM force field library. Given residue name are not canonical residue and hence their parameters have to be generated and appended as suggested by Dr Ayaz.

The Sundarbans is formed by a cluster of islands linked to the mainland by waterways. To get around, one must rely on boats. Several villages in these islands are home to women whose husbands have been killed by tigers. ‘Tiger Widows’ they are called. But I have also witnessed another side of the coin in this visit. Many women are engaged with the fish drying occupation with their husbands. After getting fishes (mainly trash varieties) off the inshore region, the women sort them and dry them, which are taken by the fish feed manufacturers for making fish feed. This is a blue supply chain, which is a matter of concern as overexploitation may initiate another dark chapter of SUSTAINABILITY

Hello!
I have been modelling the distributions of two orchid species across the island of Puerto Rico, and I have received very promising results from Maxent's output of their current distributions (AUC values around 0.90). I used Worldclim variables, elevation, and land use as my environmental layers.
The next step in the project is projecting this output against future climate scenarios for the island. I have been using the GCM database at http://www.ccafs-climate.org/data_spatial_downscaling/ since they also used the bioclim variables. So far, I have only modeled their distributions against one climate model, and the output did not incite much confidence to stand on it's own (RCP2.6 had very similar results to RCP8.5 by 2050). Due to the inaccuracies and uncertainties of downscaled climate projections across fine-scaled, small spatial areas, I am thinking that I should use multiple climate models for this project.
However, I am unsure how many different climate models I should use to adequately represent the distribution possibilities on the island. What are some general practices/experiences that people might recommend for this situation?

Hii everyone,
l am using one GCM model for future dataset of 2050 and 2070 with three SSPs.
1. did i need to find less correlated variables for all the SSPs of different time, and then run the model separately on them.
2.if yes, in case if current data had 7 less_correlated variables but future data of 2050 with SSP 126 , 245, and 585 had 4 less_correlated variable and data of 2070 SSP 126, 245 and 585 of 2070 had 6 variable.
in this case how many less correlated variable i should take for modelling. i need all or common one?

Working on an islanded microgrid consisting of two grid-forming units fed by ideal dc sources and there is a common load. initially, only one unit is supplying the load and the other unit is disconnected. synchronization starts at t=1 s and after a specified synchronization criteria is met, the unit is connected. The problem is that the unit does not contribute in power sharing though it is properly synchronized. The control system includes droop control for power sharing, secondary control for voltage amplitude and frequency restoration, and synchronization loop.

Are you working on PLANT CONSERVATION IN MEDITERRANEAN AND MACARONESIAN ISLANDS? Submit your abstract for the Symposium (n. 202) at the XX International Botanical Congress in Madrid (21-27 July 2024)!
The deadline for abstract submission is November, 30 for oral presentations and February 1, 2024, for posters.
Link to the congress: https://ibcmadrid2024.com/
With about 10,000 islands and islets, the Mediterranean Basin encompasses one of the largest “archipelagos” in the world. For many biogeographical and political reasons, the region of Macaronesia - mainly consisting of the Atlantic archipelagos of the Azores, Madeira, Canary, Cape Verde and the Salvage Islands - shows affinities and a potentially interesting comparison with the Mediterranean. For instance, evolutionary studies showed in both regions an intriguing plant distribution pattern shaped by a series of interconnected geological and paleoclimatic events, including up to the most recent Quaternary climatic fluctuations. Several floristic studies displayed a resulting high degree of plant endemism for both insular regions, which is currently similarly threatened by several human-related pressures, such as alien species introduction, climate, and land use changes. The main purpose of this symposium is to bring together important research in these areas to share scientific knowledge and improve comparisons and possible collaborations for more comprehensive conservation strategies. Among others, floristic studies showing plant phylogenetic and trait diversity can help define priorities and challenges for conservation. Prominent examples of practical conservation activities in specific island territories could be of interest for their possible replication. Although the Mediterranean and Macaronesian islands represent a fraction of the global land mass, they comprise several countries - some of them historically overpopulated - and constitute a representative case study to be replicated in other island and non-island contexts.

how is it the Chinese are using the terra Nellus in its action of building the artificial island in South China Sea. is it abide with the unclos?
Relevant answer
Answer
The term "terra nullius" refers to land that is considered nobody's territory or unclaimed territory. The idea of terra nullius has been historically used in various contexts, including colonialism, but its application to territorial claims in the South China Sea, particularly the Spratly Islands, is not entirely accurate.
China's claims in the South China Sea, including the Spratly Islands, are primarily based on historical assertions and what it perceives as ancient rights. China claims that it has historical evidence of sovereignty over the islands dating back centuries. The concept of terra nullius is not explicitly invoked by China in its claims in the South China Sea.
The United Nations Convention on the Law of the Sea (UNCLOS) is the international legal framework that governs maritime boundaries and rights. The UNCLOS establishes rules for the delimitation of maritime boundaries, exclusive economic zones, and the rights and responsibilities of states in maritime areas. The South China Sea has been a source of territorial disputes among several countries, including China, Vietnam, the Philippines, and others.
China's claims and actions in the South China Sea have been a subject of concern and contention among neighboring countries and the international community. While UNCLOS provides a framework for resolving maritime disputes, not all countries involved in the South China Sea disputes have agreed to submit their claims to international arbitration. China, for example, has not accepted the 2016 ruling by the Permanent Court of Arbitration, which rejected China's historical claims in the South China Sea and upheld the Philippines' rights under UNCLOS.
In summary, China's claims in the South China Sea are based on historical arguments rather than the concept of terra nullius, and the application of these claims to UNCLOS is a complex and disputed issue. The situation is influenced by geopolitical factors, historical claims, and the interpretation of international law.

Relevant answer
Answer
It's going to be difficult beat the ~$50 price of something like the Thermochron 4K. I guess if you need the capabilities of the 8K version, you'll double the price. The main issue in getting something cheaper is getting something that doesn't require $200 of your time to assemble and deploy. It's also going to be hard the beat the ruggedness of the iButton with cheaper solutions.
I would suggest looking at something like a disposable cold chain tag. There are several companies that make them, but Freshliance is readily available through common retailers and on-line stores and can be <$10 for a 30 day tag when purchased in bulk.
Other options are certainly available if you shop around for temperature loggers on-line, but they are sometimes very application specific and you don't really give any detail about your specific requirements (e.g. logging frequency, study duration, physical location requirements, etc...).

In our last monograph "A new paradigm of formation of accumulative relief in shallow areas of oceans and seas" (Ukrainian), the exogenous theory of the formation of underwater and above-water accumulative bottom relief forms is called into question. Look at the photo of the strait between the Sea of ​​Azov and the Black Sea. In the Sea of ​​Azov, the level is higher (two rivers flow into it) and storm surges often occur both from the north and from the south. Very often current velocities exceed 100 cm/s. Based on the exogenous theory, there should not be sandy islands (spits) in the strait. They exist contrary to the exogenous theory of the formation of the bottom relief of shallow waters. The storm theory of bottom relief formation cannot explain why the accumulative bottom relief forms are stable for hundreds of years. This can be seen by looking at the bathymetric maps of the Sea of ​​Azov made 200 years later. Please comment and ask questions.

My Master's thesis (1990) showed that storm-driven erosion was eating away the marshy borders of a large bay (Delaware Bay, USA) versus daily wave action. Since that erosion was from subaqueous and not subaerial forces, the sub-aqueous near shore-environment, though not studied in my thesis, logically received that erosion energy first before the storms impacted the adjacent marsh scarps. So to answer your question: no, there is no reasonable reason to doubt.

Carl Jung said that there are archetypes and shadow archetypes related the end of the journey (the ruler, the magician, the sage, and the wise fool). The Ruler moves from taking responsibility for oneself through working with one’s own group or community to concern for society or the planet. Examples include Aslan, King Arthur, Max in Where the Wild Things Are, Jupiter, Obi Wan Kenobee, The Lion King, Woden, and Zeus. The Magician moves from healing and noticing extrasensory experiences through acting on visions to connecting everything with everything else establishing mental, emotional, and spiritual connections. Examples include Gandalf, Genie, Hermione, Merlin, Mary Poppins, Harry Potter, Samantha in Bewitched, The three Witches in Macbeth, and The Wizard of Oz. The Sage moves from searching for the truth through skepticism to an understanding of the complexity of truth. Examples include the professor in Gilligan’s Island, Jimminy Cricket, Dumbledore,The Fairy Godmother, Galdalf, Luke Skywalker, and Yoda. The Wise Fool or Trickster moves from treating life as a game through using cleverness to trick others, to living life one day at a time and enjoying each special moment. Examples include Anansi the Spider, The Cat in the Hat, Coyote, Ferdinand, Forest Gump, The Hare and the Tortoise, Huckleberry Finn, Raven, Tom Sawyer, Sawyer on Lost, Scheherazade, and The Wizard of Oz.

I found a worm that making a sandy mound with circular opening in its peak. The mound laid in intertidal seagrass area in Pari Island, Indonesia. I assumed that it is probably sipuncula, but I don't know the genus a and the species of this organism. Can anyone help me to identify this worm?
Relevant answer
Answer
Hi Allsay,
What you have is definitely a sipunculan that could belong to one of 3 genera: 1) Sipunculus, 2) Siphonosoma, or 3) Xenosiphon. I am attaching a paper that has an extensive reference section which can be used to track down some sipunculid taxonomic keys to find out exactly what you may be looking at. Below you can find 3 links that should be useful as well. The easiest is to request assistance from a sipunculid expert! The WORMS web site (see link below) will have them listed when you look at the “Taxonomic edit history” section. Click on their name and you should be able to get their e-mail address. Sorry I can't be of more help, and good luck!
Cheers,
Tom

The model has a microgrid is connected to the main grid. Calculation of the rate of change of voltage is required for the islanding detection technique I need to use. Is there any MATLAB code or Simulink or suggestion about that?
Relevant answer
Answer
I recommend using Micro-Cap (http://www.spectrum-soft.com/download/download.shtm). All EE's at Emerson used Micro-cap, even though it cost $4,000 each. There are no other electronic SPICE modeling programs even close to Micro-Cap capability.
Micro-Cap is now free. Andy Thompson, owner of Spectrum Software, has retired.
Micro-Cap does worst case analysis --- changing the tolerances of components --- changing the temperature --- etc. And it is easy to use.
I have used Micro-Cap for all of my electronic designs since 2001. When I tested prototypes, they worked exactly as the model predicted.
The website --- https://NDAcademy.FoxPing.com/ --- 2.8 Electronic Cascade RC Filters --- and --- 7.2 Electronic SPICE Models --- provide examples.

Dear Shamsher Ansari you are not wrong and I agree that the inverter needs a controllable input.

Answer
The following steps: 1, the system load status detection step: When the system load during normal operation of the island grid system changes, it is transferred to the next step; 2. Diesel generator starts stopping control processing step: If the diesel generator is working The energy storage has been added to the high state, and the diesel generator is processed. If the diesel generator is added to the energy storage, the diesel generator is stopped; if the diesel generator is started to stop control processing After the island grid system still cannot operate stably, then it is transferred to the next step; Machine, energy storage and other equipment for flexible examination, charge, extending the service life of the equipment.

Answer
Clans were often identified with a geographical region of Scotland; for example, the Armstrong Clan started in the Borders, the MacGregors in Argyll, and Clan Campbell controlled over most of the Scottish Highlands.

It has been noted in many researches that gully headcuts are main drivers of gully erosion and upstream migration. Most commonly used definitions describe gully headcut as near-vertical step at which most intense erosion occurs, e.g.:
Rengers and Tucker, 2014. - Headcuts are near‐vertical steps that erode the valley network by migrating upstream over time (Bull and Kirkby , 2002) and add mobile sediment to gully channels downstream (Tucker et al. , 2006).
Vanmaercke et al., 2016. - A gully headcut is a natural, nearly vertical drop in gully channel-bed elevation (Poesen et al., 2003).
Since these are predominately descriptive definitions, I would like to know is it possible to delineate quantifiable definition of a gully headut ?
Such definition would be based on measurements that could be extracted from high-resolution DEM (e.g. required slope angle; headcut horizontal length; headcut height…), rather than on the descriptive, non-quantifiable information.
I understand that such definition would vary depending on local terrain characteristics and characteristics of local gully erosion predisposing factors. But even general quantifiable definition would be very helpful for detection of gully headcuts.
In the attachment is large gully headcut from my research study area, located at Pag Island, Croatia. Within Pag Island large number of small headcuts can be found, that are less distinguishable then the one in this picture.

someone wrote FDZ as a false detection zone and others mentioned it as a fault detection zone. please provide any information, material regarding the calculation of FDZ for an islanding detection technique
Relevant answer
Answer
Fault (false) detection zone includes non-islanding conditions wherein an employed islanding detection methodology detects wrongly as islanding. For instance, the voltage of a weak grid may violate the standard range during a large capacitor switching, tripping the voltage relay.
So, an islanding detection signal should be 1) triggered during islanding events accurately (minimum NDZ) and 2) should not trip in non-islanding events (minimum FDZ).

I am looking for research (or researchers or activists) doing research on mining in New Zealand, especially north island and the Coromandel Peninsula. Thank you, Dr. Robin Broad
Relevant answer
Answer
You could contact Dr. Anthony Christie (T.Christie@gns.cri.nz ), now retired from the NZ Geological Survey, an expert in the nature of the metal deposits of New Zealand, and most aspects related to mining in the country. With regards to banning mining, if this comes about, the computers we are using (consisting of dozens of metals) will not be replaced; the mobile phones that are produced (over 1 B/year) in the world will be no more (the iPhone uses 62 elements to make one phone, with many being critical in that they are the only metal that enables certain functions); of course, we could consider cars, buildings, roads, power stations, etc.; and all of the green energy sources (renewable energy technologies such as wind and solar require four to six tonnes of copper per installed MW); a petrol car needs 10 kg Cu per vehicle, whereas an electric car consumes 40 kg Cu in its production. So banning mining is not the answer, nor is it anywhere near an option. Fundamentally, banning mining results in the export of the issue to other countries while continuing to import metals for industry, construction and consumables. This is why the EU now is encouraging metal production from within its borders.

There isn't really a species divide by classic political divisions of Europe meaning Portugal and Britain until Eastern Europe, or further to the Bosphorus or the Ural Mountains.
Although there are genetic variations of taxinomical cleavages with small geographic distance as well.

If you are using large number of samples, then you can align those genes using some multiple sequence alignment tool such as MUSCLE, and then construct the phylogeny using MEGA X software.
If you have only one sequence in question, you can perform NCBI BLAST search of the genes of interest. Then you can pick related sequences from there and perform phylogeny using MEGA X software.

As I could demonstrate, there is a gravityless point in Formentera island, marked by a 3500-years old megalithic unexplained monument. This particularity, probably the archaic scar of a former very big earthquake, explains some strange liquids behaviors, such as disappearing gasoline or capillary rocks sucking seawater to pee edible water in the no-springs isolated island. I consider it may open up a new scientific future for Formentera island, allowing experiments that until now could only be done in gravity less outer space. The Covid19 emergency, as the virus does not seems to develop properly in Formentera, as it is doing in Earth's altiplanos, where gravity is less, should lead us to a more attentive consideration of the small Balearic island. Who would like to participate in such a thinking tank?
Relevant answer
Answer
I showed how water withdraws CLOCKWISE over there, at the opposite of the rest of the Northern Hemisphere and even in my house 5km away. I consider it the logical consequence of a former gigantic earthquake Fukushima-type where this place was the epicenter. The Fukushima one left a scar in the Earth's gravity field, detected by European Space Agency's satellites. In Fukushima, gravity is also less and so is covid 19 contamination. I think the men who built the megalithic site in Formentera were coming from Algerian Sahara, namely Tassili N'Aljer, where double circle megalithic structures can be seen too. I believe this place was an amphidromic point, too, a place where water comes to but withdraws the opposite. Probably due to severe drought, they went up to the Mediterranean coast. Still in nowadays Algiers a strong current 6 knots pushes you North effortless up to Formentera island. I think those guys were looking for the place where waters go to and withdraw the opposite way. But the very strange thing is there are no life signs of them in Formentera, no sculpted stones, no tools, no ovens, no houses, only two megalithic structures, very different and not seeming from the same time. Ca Na Costa monument is more restored but also seems more complex, meaning more recent. No similar structures happen in the rest of Balearic islands, either in continental Spain, or France, or Italy.

Some islands in certain parts of the world get very little rainfall. Some of these islands with significant populations often either import water or desalinize seawater to obtain water for domestic purposes. Another approach would be to drill a well. What might be some difficulties in using well water in these situations?

I agree with your answer, extra groundwater pumping may lead to salt water entrusion (mixing of sea water with fresh water).
To use well water you need to analysis the well water quality to discover its suitability for using in domestic purpose.
