1. 1. Free cooling and PVT integration in a ground-source heat pump (GSHP) system

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Christopher Pourier; [2023]
   Keywords : Ground-source heat pump; borehole; GSHP; photovoltaic thermal collector; PVT; free cooling; Ytjordvärmepump; borrhål; GSHP; solfångare; PVT; frikylning;

   Abstract : The performance of ground-source heat pump (GSHP) systems can be negatively affected over time by soil temperature degradation of boreholes (BH) in heating dominated climates. Land area is scarce in the dense urban environments typical of multi-family houses (MFH) and can lead to accelerated degradation- in tight BH fields. READ MORE

3. 2. Black Hole Dynamics in Stellar Clusters

   University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Astronomi - Genomgår omorganisation

   Author : Markus Strickert; [2022]
   Keywords : Black Holes; Globular Clusters; Dynamics; Intermediate-mass black holes; Simulations; Physics and Astronomy;

   Abstract : Star clusters can harbour many exotic objects, including black holes (BHs), X-ray binaries and blue straggler stars. In dense stellar environments like globular clusters (GCs), two-body relaxation drives their dynamical evolution, where gravitational interactions between stars strive to equalize their kinetic energy in the cluster.

4. 3. Escaping Compact Object Binaries from Globular Clusters

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation

   Author : Annie Csomor; [2022]
   Keywords : Compact object binaries; binary black holes; BH-NS binaries; escaping binaries; globular clusters; escaping compact object binaries from globular clusters; escaping compact binaries; Physics and Astronomy;

   Abstract : Since 2015, the LIGO-Virgo-KAGRA scientific collaboration (LVK) has detected gravitational waves from more than 90 merging compact object binaries using ground-based interferometric detectors. Compact objects orbiting in binary systems emit gravitational waves leading to a loss of energy. READ MORE

5. 4. The retention of black holes in globular clusters

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

   Author : Wuxueman Liu; [2021]
   Keywords : Physics and Astronomy;

   Abstract : We simulate the velocities of formed Black Holes to determine the fraction of retained Black Holes in 152 Globular Clusters. The model we used for the escape velocity is from Plummer. The scenarios of the natal kick are Neutronstar like kicks and momentum conserving kicks. READ MORE

6. 5. Standing long jump compared to vertical jump as a field test for assessing leg power in firefighter trainees : A correlation study from a gender equality perspective

   University essay from Högskolan i Halmstad

   Author : Mimmi Bringsén-Bornegrim; [2021]
   Keywords : Firefighters; the rescue service; standing long jump; standing broad jump; vertical jump; gender equality; Brandmän; Räddningstjänsten; rektyteringstester; stående längdhopp; vertikalt hopp; jämställdhet;

   Abstract : Background: Within the rescue service, a varied background is needed to increase the possibility of delivering equal service to the citizens. At present, there is a skewed gender distribution within the municipal rescue services, with only a couple of percent of the firefighters being women. READ MORE
