1. 1. Starbursts at Cosmic Dawn : Formation of Globular Clusters, Ultra-Faint Dwarfs, and Population III star clusters at z > 6

   University essay from Stockholms universitet/Institutionen för astronomi

   Author : Olof Nebrin; [2022]
   Keywords : Cosmology; Galaxy Formation; Globular Clusters; First Stars; Dark Matter; Cosmic Dawn; Reionization; Ultra-Faint Dwarfs;

   Abstract : In the standard model of cosmology (ΛCDM) the first stars, star clusters, and galaxies are expected to have formed in short bursts of star formation in low-mass dark matter halos at high redshifts (). Up to this point, attempts to predict the properties and abundances of these luminous objects have made use of numerically expensive cosmological simulations. READ MORE

3. 2. Studies on the application of gas cooling as used by firefighters

   University essay from Lunds universitet/Avdelningen för Brandteknik

   Author : Jan Bonnier; [2017]
   Keywords : Gas cooling; Firefighting; Fire Service; 3D-technique; Technology and Engineering;

   Abstract : Gas cooling is a technique used by firefighters to create a safer work environment inside a compartment fire. By spraying water into the smoke layer, the smoke layer temperature will decrease significantly. Next to the lower temperature, the flammability of the smoke layer will also decrease. READ MORE

4. 3. Studies on the performance of firefighter’s gas cooling

   University essay from Lunds universitet/Avdelningen för Brandteknik

   Author : Matthias Van De Veire; [2016]
   Keywords : Fire; Engineering; Gas cooling; Firefighting; fire service; suppression; Technology and Engineering;

   Abstract : Gas cooling is a technique used within the fire service to reduce the risks of the hot gaseous layer and create a better visibility. It is achieved by applying water into the gaseous layer. Successfully performing or implementing this technique is something that has not yet been accomplished in every brigade. READ MORE

5. 4. Reducing Energy Consumption through Optimization of the Operating Conditions of the Gas Trunk Pipeline

   University essay from KTH/Kraft- och värmeteknologi

   Author : Alexey Albutov; [2013]
   Keywords : main trunk pipeline; optimization of gas pipeline; energy saving technologies for gas pipeline; optimization of operation mode of compressor station;

   Abstract : Gas supplying process for consumers needs sufficient share of energy for upstream, midstream and downstream purposes. In spite of a huge amount of great investments into the industry it is still available to improve the efficiency of energy usage inside the industry. The biggest share of energy consumption is within transportation sector. READ MORE

6. 5. Investigation on the gas-cooling effects of CAFS

   University essay from Lunds universitet/Avdelningen för Brandteknik; Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

   Author : Erik Lyckebäck; Jacob Öhrn; [2012]
   Keywords : CAFS; compressed air foam systems; extinguishing methods; full-scale experiments; gas-cooling; high pressure water mist; structural firefighting; tryckluftsgenererat skum; brandgaskylning; fullskaleförsök; förhöjt lågtryck; högtryckssystem; inomhusbränder; rökdykning; släckmetoder; Technology and Engineering;

   Abstract : This report investigates the gas-cooling effects of compressed air foam (CAF). A literature review has been made on the subject and on related issues in order to gather information. Two experimental series were conducted, the first to evaluate the gas-cooling properties of CAF compared to water. READ MORE
