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.
I am interested in research relating to Female Entrepreneurship. I am currently conducting research on Female Entrepreneurship in Malta, a small island state in Europe.
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!!
I had plated my cells on 3rd July, and checked them yesterday on 5th July. usually after two days I can see confluent enough growth, around 60% since I plate them 4:10 ratio. But yesterday, the islands of cells were small and surrounded by black debris? around it, and small cell like structures. Their live percentage when I last split was also low, around 30% but it was 3.5 million cells/ml. Is there any way to make them healthy again??
I am studying the turbid water reefs of Inhaca Island in Mozambique and I need tide data from 1970. I see NOOA has a website for USA but is there any resource at global level which I could find the data from Mozambique? Thank you
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
I have a CVD-prepared material. The problem is that the LASER covers a smaller area than the islands, so I see localized effects. Sometimes, the intensity of the silicon peak is larger than the sample, and sometimes, it is otherwise. How do I deal with this?
I really appreciate any help you can provide.
I am writing a project proposal on food security and sustainable farming in solomon islands context
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. "The following residues do not have a template: A:ACE0, A:HYP2, A:HYP5, A:HYP8, A:HYP23, A:HYP26, A:HYP29, B:HYP2, B:HYP5, B:HYP8, B:HYP23, B:HYP26, B:HYP29, C:ACE0, C:HYP2, C:HYP5, C:HYP8, C:HYP23, C:HYP26, C:HYP29."
Kindly suggest me to rectify this.
Thanks

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?
Sir,
I found a delicate sea whip in Saint Martin Island about 11km far away from the island. So far I know you have some good research on the places on the island. I want to know did you got that species in the sea area.

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.
Attached simulation results from MATLAB/SIMULINK

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?
living in a place with low gravity spot (9,375), probably due to an archaic force 9+ earthquake 500.000 years ago (only perceptible through ESA satellite, see photo), Formentera island, in Balearic archipelago, Spain ((PDF) (PDF) FORMENTERA WITH LESS GRAVITY (researchgate.net), and following with friends, music and flowers, the holy sunset tradition, that last longer in this part of the island. Sometimes, color red even performs an unusual comeback after violet. So, I wondered if light and spectrum's colors could be influenced by gravity. And of course, they are Why Is Light Affected By Gravity? (forbes.com) . Now, I dream of making an artistic movie on Formentera's sunsets, with solid and revolutionnary scientific bases. What are you thoughts about my crazy idea?
I am seeking to make an inventory and evaluate storybooks or projects that are intended to introduce concepts of gender equality or feminism to young children in the Sub-Saharan region or the Islands of the Eastern part of the Indian Ocean within the last 10-15 years.

It was collected from a freshwater stream in Andaman group of islands.
There are sensor for urban air temperature (heat island effect study) at better quality/price than iButton? I don't need higher quality sensor than IButton, but mainly just T sensors at lower cost.. thanks!
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.

Dear all,
I have a question about how to optimally determine the value of active power droop gain mp in islanded microgrid which shares a certain load.
I use this formula: w=wnominal -mp*p and I put P=the load connected to each inverter and I assume the value of w which is the minimum frequency that I do not want to go below it and from these values I calculate mp. Are these steps correct ?
I am using SIMULINK software and I would like to know how to determine the power rating of each VSI and if that is related to the DC link voltage. what is the criteria to choose the values of mp and nq to share the connected load between the different DGs ?
Hi, I'm trying to assign different material to this geometry (attached), cortical bone for external part (and internal 'islands') and bone marrow for internal part (no islands), but the section is empty while trying to assign materials. Do anyone know what problem is occuring?
Appreciate every advice
Thanks
Under the islanding conditions, the system is being modeled to supply power to the system with distributed power. Distributed power sources include PV and ESS. However, when the system is in an islanding condition, a very large overvoltage or low voltage occurs when only PV or ESS is installed. In this case, what is the solution?
We analysed the secondary data collected from the archives of University of Calcutta and Techno India University, West Bengal and several relevant literatures over a period of more than three decades (1984-2016). We considered Sagar Island as the representative of Indian Sundarbans region for this study. We observed an increasing trend in near surface air temperature in all the three seasons, which may be attributed to change of land use pattern due to intense industrialization, unplanned urbanization and expansion of tourism units coupled with establishment of shrimp farms in all the regions at the cost of mangroves. The adverse impacts of such anthropogenic activities related rise in near surface air temperature on marine estuarine biotic community is discussed in a qualitative manner. However is it applies in your place also?

Was wondering if anyone has done any research on cross-border transmission of Malaria between the Shortland Islands (Solomon Islands) and Bougainville (PNG). The two countries are very close to one another at these two points and people travel by sea between these islands. I have not been able to locate any articles.

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. Can you think of additional archetypes and shadow archetypes (ala Northrup Frye and Carl Jung) related to end of the journey?
I've ROMS model data of ocean surface current, which has a very High resolution. But still, near the coasts of a partially isolated island I don't have data(for context see the image below).
If I want data somewhat more into near to the land, then what method should be approached.
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?

Dear all,
I know that Uropathogenic Escherichia coli (UPEC) frequently has pathogenicity islands (PAIs), that contribute to their virulence. But I wounding if Avian pathogenic E.coli has the same islands or it is associated only with UPEC
I found this insect in the digestive tract content of Hypoatherina temminckii (marine fish). The sampling location in seagrass waters of Karang Congkak Island, Kepulauan Seribu (Seribu Island), Indonesia. I can't identify the insect groups, I just suppose this is part of Diptera but have never seen marine (or semi-aquatic) insects in my sampling location.
Imagine sleeping, walking, drinking a cup of coffee on an Artificial Floating Island without pillars but with anti-gravity or magnetic repulsion force just an idea

Is it uaing dual loop cascaded structre, or using single current loop control.
Noting that the battery and supercapacitor are controlled with dual loop structrue considering the Dc bus voltage deviations.
Thank you for your reply and feedbacks.
Dr. Andrew Lind (University of the Highlands and Islands) and I (Montgomery College, Maryland) are writing a book on Scottish Royalist Military Units, 1639-54. Scottish Highland clans raised many of the units. Does anyone have suggestions for primary and secondary sources? Thank you very much.
What could be the reason behind the depletion of Rb and Ba in an ultramafic rocks with Island arc tectonic setting..Generally Island arc basaltic rocks are LILE enriched and HFSE depleted?
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.
During the past few years a number of papers have been published on the coral reefs of St. Martin's Island, Bangladesh. I would like to invite our colleagues working in the northern Bay of Bengal to have a look at our recent comment on the subject. Our comment can be found at:

Hello curious visitor! Perhaps you could help me out here. I'm working on a paper which includes a description of nearshore/inner shelf sediment characteristics near Herschel Island in the Canadian Beaufort Sea (see attached figure). I need some references in the discussion to contrast and compare my findings with other nearshore clastic settings elsewhere. Besides Miles Hayes' dissertation (SEDIMENTATION ON A SEMIARID, WAVE-DOMINATED COAST (SOUTH TEXAS) WITH EMPHASIS ON HURRICANE EFFECTS, 1965), I'm not aware of comparable literature. I would very much appreciate any hints.
Thanks!
I have camera traps data which was deployed at several sites (islands). The data consist of only N (abundance; independent image) of each species at their respected islands. No occupancy modelling could be run as I do not have the habitat data. Is it possible to calculate the occupancy and probability without the temporal data/repeated sampling (the week the species was detected)? Or would calculating the Naive Occupancy would do? Furthermore, does Occupancy and Probability has a range of high and low?
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
Do anybody know any papers discussing the crystallization temperature of back-arc basin basalt (BABBs) and island arc basalt (IABs)?

I am searching for literature that can help me define Europe.
Both, from a biological and social perspective.
How one can define what is Europe? especially when dealing with species distribution or the delimitation of countries. What is Central Europe? Northern, Southern, and so on?
How can you really define this, perhaps another perspective would be Orography??
How to deal with Islands, like Corsica or Azores that are territories of certain European Countries, but are definitely not near "continental" Europe?
Any help is highly appreciated
I am currently working on islanding detection and control in distributed generations. I would kindly ask that you recommend a real-time simulation tool that helps me in this study. I have tried using MATLAB but it keeps freezing and slowing work for me. The simulation tool should be fairly easy to use but robust so that I can get the needed components for modeling the islanding phenomenon and simulate it.
Plz share controller for grid supporting grid forming inverter so it can operate in both modes grid connected and islanded mode.
Am going to do a study over the Spotted Deer species (Axis axis) in the Andaman and Nicobar Islands, India. It was the first introduced fauna species in the tropical Island. It was brought to the Islands from the Indian mainland in the early 20th century and its population has grown extensively at this date and spread to almost all parts of the Island archipelago, as there's no predator to this species in the Islands. I want to do a study on the impact of this species on the Island ecosystem. I wanted to get an idea on what type of methodology can be implemented for this work. My area of study is an enclosed Biological Park with an area of 40 hectares.
Can someone help with any tips on how to look for the gene islands, what software to use for alignments, and build the tree.
I have already constructed using only 1 primary gene in the island and compared it across different phylum. Now I would like to expand and look into all the genes present in the island or particular operon. Thank you
Does climate drive (directly or not) inter/intraspecific competition in tetrapod species? And more specifically on islands, along a North-South cline? Many thanks for our help and/or references :-)
Dear all, hope you are keeping well at the moment.
I am trying to study an islanded microgrid with one grid-forming converter (GFMC) and several grid-feeding converters GFC supplying power to the island loads.
My query is how to calculate the size of the GFMC, I mean the minimum converter rated power that is required to keep the grid voltage/frequency stable. For instance, should this rated power be bigger/equal/a fraction of the installed power in the GFC/in the loads?
I would appreciate that you could provide some advice and if possible, recommend some papers that could serve as guidance.
Thanks in advance and BR!
I’m a graduate student and I’m going To start my thesis research , could you help me to find something related to the islanding detection to research about ,thank you at all
What will be accuracy of this island width estimation?
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?
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?
Hello all!
I'm trying to conduct an SDM analysis in R regarding a species which only occurs in the intertidal area.
I need to be able to restrict my geographical range to a range of points in the coastline around the continents and islands, in order to prevent the software from predicting species occurrences, lets say, for the countryside (places with similar environmental characteristics but very very far away from the coast).
I am aware I can do it with a shapefile but have yet to find one (and the way to implement it) that fits.
Can anyone offer me a nudge in the right direction please?
