This 142 cfs (92 MGD, 14,511 m3/h) cooling water intake is located in Albany, NY and provides water to both heat and cool buildings owned and operated by the state of New York. The facility was required to install 0.75-mm slot size wedgewire screens with a through-screen velocity of no more than 0.5 fps (15 cm/s) to reduce both entrainment and impingement in accordance with NYS Commissioner Policy #52. Fish species offered protection by this screening system include river herring (Alewife and Blueback Herring), Atlantic Sturgeon, Shortnose Sturgeon, and tens of other anadromous, catadromous, and resident Hudson River fish species. This project is to be fabricated in 2021 and installed in 2022 and this page will be updated as the project progresses.
Springhill mining disaster may refer to any of three Canadian mining disasters that occurred in 1891, 1956, and 1958 in different mines within the Springhill coalfield, near the town of Springhill in Cumberland County, Nova Scotia.
The mines in the Springhill coalfield were established in the 19th century, and by the early 1880s were being worked by the Cumberland Coal & Railway Company Ltd. and the Springhill & Parrsboro Coal & Railway Company Ltd. These entities merged in 1884 to form the Cumberland Railway & Coal Company Ltd., which its investors sold in 1910 to the industrial conglomerate Dominion Coal Company Ltd. (DOMCO). Following the third disaster in 1958, the operator Dominion Steel & Coal Corporation Ltd. (DOSCO), then a subsidiary of the A.V. Roe Canada Company Ltd., shut its mining operations in Springhill, and they were never reopened. As of 2015 the mine properties, among the deepest works in the world and filled with water, are owned by the government of Nova Scotia, and provide Springhill's industrial park with geothermal heating.
Census data are widely used in the United States across numerous research and applied fields, including education, business, journalism, and many others. Until recently, the process of working with US Census data has required the use of a wide array of web interfaces and software platforms to prepare, map, and present data products. The goal of this book is to illustrate the utility of the R programming language for handling these tasks, allowing Census data users to manage their projects in a single computing environment.
Aid organizations say they're seeing signs that Russia's invasion of Ukraine is driving up global food prices and pushing millions of people into hunger.
A food price index tracked by the United Nations Food and Agricultural Organization shows that prices spiked 12% between February and March to its highest point since the index started in 1990.
Ukraine and Russia provide an outsized share of the world's supply of key foods including wheat, corn, barley and more.
The impact on people who were already struggling to afford food has been severe, aid groups say. In Afghanistan a month ago, 55% of people were at crisis levels of food insecurity. Now the number has risen to 65%.
What I’m learning with my Facebook Map Atlas of the Day
Since mid-January, I have been posting a new Map Atlas of the Day to my Personal Facebook account. Most of those maps are created with QGIS, using data I’ve been able to pull from a variety of sources but a lot from the tidycensus R package and exported to an GPKG. I tried to spend less then 10-15 minutes each day on the map.
Each day creating the map, it makes me look for ways to automate processes, pull data together quickly. Often I discover a new problem with the layout, forcing me to dig a little deeper into the documentation, learning a new function or technique in QGIS. As time is tight, I often try to do things as quickly. Once you do things constantly, you get quicker and quicker each day, and find ways to take shortcuts. You find ways to improve beauty, make things more visually attractive.
