The inventory will come up by March 2012. The commission, in April 2009, initiated the project of Rs3 crore with the Agharkar Research Institute, Pune. In all, 14 universities in the state have been given the task of compiling the data of the medicinal plants in the different districts. Shivaji University (SU) has been given the responsibility of compiling the data from Sangli, Satara and Kolhapur. The university’s botany department’s associate professor, DK Gaikwad, is co-ordinating the project in the SU. Medieval Fantasy City Generator by watabou This application generates a random medieval city layout of a requested size. The generation method is rather arbitrary, the goal is to produce a nice looking map, not an accurate model of a city. All the actions and options are accessible via the context menu. Hot keys: 👉For development news and related stuff please check a dedicated reddit community. The first version of this generator was created for the monthly challenge #17 of the proceduralgeneration subreddit.
MayaArch3D A web-based 3D GIS for archaeological research The MayaArch3D Project has built a virtual research environment for the documentation and analysis of complex archaeological sites —specifically, it is a web-based, 3D-GIS that can integrate 3D models of cities, landscapes, and objects with associated, geo-referenced archaeological data. An international, interdisciplinary project This international, interdisciplinary project brings together archaeologists, art historians, and cultural resource managers with experts in geosciences, remote sensing, photogrammetry, 3D modeling, and virtual reality from various institutions in Germany, the US, Italy, and Honduras. Case Study: UNESCO World Heritage site and ancient Maya city of Copan, Honduras The digital collections used to demonstrate the system contain basic information for other ancient Maya cities in Central America, but focus on the archaeology of Honduras and specifically Copan.
logy Magazine Atmospheric oxygen really took off on our planet about 2.4 billion years ago during the Great Oxygenation Event. At this key juncture of our planet’s evolution, species had either to learn to cope with this poison that was produced by photosynthesizing cyanobacteria or they went extinct. It now seems strange to think that the gas that sustains much of modern life had such a distasteful beginning.
All he is saying, is give pee a chance How the waste was won – a new pop-up restaurant for the Melbourne Food and Wine festival, which combines art, food and ecology, is about creating a sustainable world. NO DOUBT there's a more polite, even more technically accurate, way of phrasing this, but it doesn't get the message across half as well. And Joost Bakker is very much about sending the world a message. Nitrogen Fixation Fritz Haber I’m haunted by one of the stories in the latest episode of Radiolab, can’t get it out of my head. Like everyone else, I love Radiolab and often sprinkle stories I learned from the show into cocktail party conversation (do I go to nerdy cocktail parties or do I make cocktail parties nerdy?) Flowers in Ultra-Violet The compilation of species will continue to be updated at irregular intervals. All species listed here have been documented, and links are added whenever I can find spare time for updating. These images are made for illustrative purposes, not as artistic statements per se. However, there are lots of food for thought in the convoluted ways Nature expresses itself, so for once the artist can step backand let the subjects speak for themselves. "Das Ding an Sich" to paraphrase Kant, or Eigenvalue of Nature.
First plants caused ice ages, new research reveals New research reveals how the arrival of the first plants 470 million years ago triggered a series of ice ages. Led by the Universities of Exeter and Oxford, the study is published in Nature Geoscience. The team set out to identify the effects that the first land plants had on the climate during the Ordovician Period, which ended 444 million years ago. During this period the climate gradually cooled, leading to a series of 'ice ages'. This global cooling was caused by a dramatic reduction in atmospheric carbon, which this research now suggests was triggered by the arrival of plants. Among the first plants to grow on land were the ancestors of mosses that grow today.
Key mechanism that regulates shape and growth of plants discovered UBC researchers have discovered a key mechanism that -- much like a construction site foreperson -- controls the direction of plant growth as well as the physical properties of the biopolymers that plants produce. The finding is a major clue in a 50-year-long quest to explain how plants coordinate the behaviour of millions of cells as they grow upward to compete for light, penetrate soil to obtain nutrients and water, and even open petals to flower. "We've known for decades that structures in plants called microtubules act as scaffolding to define the direction of cell expansion," says Professor Geoffrey Wasteneys, a UBC botanist and Canada Research Chair in Plant Cell Biology. "These are tiny multipurpose cylinders that grow, shrink and self-organize to transport cargo, capture and position large structures such as chromosomes, and establish the shape of cells. But we haven't been able to determine how these tiny microtubules are organized into scaffolds in the first place."
