File mirroring scenarioDoug Moncur

This document discusses mirroring a collection of files from a central archive to a local community repository. It proposes building a machine at the central archive to test mirroring and load the data, then ship it to the community. The community could then build their own front-end using the mirrored data, either developing their own interface or using Dspace. Updates from the community could then be periodically mirrored back to the central archive. Inspiration is drawn from work done by Tim Hopkins at the University of Kent to develop robust mirroring technology using turn-key packages that allow any site to set up their own mirror service on cheap hardware.

Scholarship in a connected world: New ways to know, new ways to showDerek Keats

The document discusses how libraries and scholarship are changing in a digital world of abundance rather than scarcity. It covers four key areas: ubiquitous computing, the social academic, research data, and free and open versus secret science. The author argues that libraries must adapt to this new environment by embracing new technologies, facilitating social and open sharing of knowledge, helping with research data management, and promoting open access over secret science.

A research and innovation perspective on Free and Open Source Software (FOSS)Derek Keats

The document discusses the benefits of free and open source software (FOSS) for research and innovation. It argues that FOSS lowers barriers to innovation by reducing costs and permissions. Many modern software innovations like Google were only possible because core technologies were freely available. The document suggests applying similar open principles to publicly funded scientific research to further catalyze innovation and knowledge growth.

YSPH VMOC Special Report - Measles Outbreak Southwest US 4-30-2025.pptxYale School of Public Health - The Virtual Medical Operations Center (VMOC)

A measles outbreak originating in West Texas has been linked to confirmed cases in New Mexico, with additional cases reported in Oklahoma and Kansas. The current case count is 795 from Texas, New Mexico, Oklahoma, and Kansas. 95 individuals have required hospitalization, and 3 deaths, 2 children in Texas and one adult in New Mexico. These fatalities mark the first measles-related deaths in the United States since 2015 and the first pediatric measles death since 2003. The YSPH Virtual Medical Operations Center Briefs (VMOC) were created as a service-learning project by faculty and graduate students at the Yale School of Public Health in response to the 2010 Haiti Earthquake. Each year, the VMOC Briefs are produced by students enrolled in Environmental Health Science Course 581 - Public Health Emergencies: Disaster Planning and Response. These briefs compile diverse information sources – including status reports, maps, news articles, and web content– into a single, easily digestible document that can be widely shared and used interactively. Key features of this report include: - Comprehensive Overview: Provides situation updates, maps, relevant news, and web resources. - Accessibility: Designed for easy reading, wide distribution, and interactive use. - Collaboration: The “unlocked" format enables other responders to share, copy, and adapt seamlessly. The students learn by doing, quickly discovering how and where to find critical information and presenting it in an easily understood manner.

CBSE - Grade 8 - Science - Chemistry - Metals and Non Metals - WorksheetSritoma Majumder

Introduction All the materials around us are made up of elements. These elements can be broadly divided into two major groups: Metals Non-Metals Each group has its own unique physical and chemical properties. Let's understand them one by one. Physical Properties 1. Appearance Metals: Shiny (lustrous). Example: gold, silver, copper. Non-metals: Dull appearance (except iodine, which is shiny). 2. Hardness Metals: Generally hard. Example: iron. Non-metals: Usually soft (except diamond, a form of carbon, which is very hard). 3. State Metals: Mostly solids at room temperature (except mercury, which is a liquid). Non-metals: Can be solids, liquids, or gases. Example: oxygen (gas), bromine (liquid), sulphur (solid). 4. Malleability Metals: Can be hammered into thin sheets (malleable). Non-metals: Not malleable. They break when hammered (brittle). 5. Ductility Metals: Can be drawn into wires (ductile). Non-metals: Not ductile. 6. Conductivity Metals: Good conductors of heat and electricity. Non-metals: Poor conductors (except graphite, which is a good conductor). 7. Sonorous Nature Metals: Produce a ringing sound when struck. Non-metals: Do not produce sound. Chemical Properties 1. Reaction with Oxygen Metals react with oxygen to form metal oxides. These metal oxides are usually basic. Non-metals react with oxygen to form non-metallic oxides. These oxides are usually acidic. 2. Reaction with Water Metals: Some react vigorously (e.g., sodium). Some react slowly (e.g., iron). Some do not react at all (e.g., gold, silver). Non-metals: Generally do not react with water. 3. Reaction with Acids Metals react with acids to produce salt and hydrogen gas. Non-metals: Do not react with acids. 4. Reaction with Bases Some non-metals react with bases to form salts, but this is rare. Metals generally do not react with bases directly (except amphoteric metals like aluminum and zinc). Displacement Reaction More reactive metals can displace less reactive metals from their salt solutions. Uses of Metals Iron: Making machines, tools, and buildings. Aluminum: Used in aircraft, utensils. Copper: Electrical wires. Gold and Silver: Jewelry. Zinc: Coating iron to prevent rusting (galvanization). Uses of Non-Metals Oxygen: Breathing. Nitrogen: Fertilizers. Chlorine: Water purification. Carbon: Fuel (coal), steel-making (coke). Iodine: Medicines. Alloys An alloy is a mixture of metals or a metal with a non-metal. Alloys have improved properties like strength, resistance to rusting.
