Fire ppt
Fire is caused by an oxidation reaction called combustion, which requires fuel, heat, oxygen, and a chain reaction. These four components make up the fire tetrahedron. To start a fire, the fuel and oxygen must be present and heated to their kindling temperatures to start the chain reaction. Once started, a fire can be extinguished by removing any part of the tetrahedron, or intensified by adding a catalyst to increase the combustion reaction rate. While fire can be dangerous, it also provides benefits like light, heat, and uses in certain ecosystems.

Triangle Fire
The Triangle Factory Fire occurred in a building with insufficient fire escapes. There was only one interior fire escape and none in the back of the building. The building had experienced previous fires and was deemed unsafe by the fire department due to insufficient exits. The owners of the factory were indicted for the death of one victim but were later acquitted. Several years later, lawsuits for victims' families were settled for $75 per death. The fire led to safety reforms and new legislation through investigations and campaigns by unions and women's groups.
Triangle Shirtwaist Factory Fire
The Triangle Shirtwaist Factory fire in New York City on March 25, 1911 killed 146 garment workers, most of them young immigrant women and girls trapped inside the building due to unsafe conditions. The owners had locked the doors to the stairwells and fire escapes to prevent theft, and firefighters struggled to reach the victims on the upper floors as the fire spread quickly. It became one of the deadliest industrial disasters in U.S. history and led to regulations for building safety and workers' rights.
Triangle Factory Fire
This document outlines the events of the 1911 Triangle Shirtwaist Factory fire in New York City. It provides background on the factory owners and poor working conditions, including long hours and locked exits. On March 25, 1911, a fire broke out on the 8th floor of the factory. Panicked workers found the doors locked and the fire escapes collapsed. 146 workers died in the fire, either from the flames or jumping from the high windows. The tragedy led to new laws improving factory safety regulations in New York.
Triangle Fire Presentation
On March 25, 1911, a fire broke out at the Triangle Shirtwaist Factory in New York City, killing 146 workers who were trapped inside. The factory had locked exits and failed to meet safety requirements. The owners were acquitted of manslaughter charges, but the tragedy spurred new legislation requiring fire safety standards, factory inspections, and better conditions for women and child workers. Von Drehle's book examines how the fire helped spark the progressive era and increased focus on workers' rights and safety reforms.
Accident prevention theories & Risk management
This document discusses accident prevention theory and risk management. It covers several accident causation theories including the domino theory, human factors theory, accident/incident theory, epidemiological theory, systems theory, and combination theory.

We present the JWST discovery of SN 2023adsy, a transient object located in a host galaxy JADES-GS

with a host spectroscopic redshift of
2.903
±

. The transient was identified in deep James Webb Space Telescope (JWST)/NIRCam imaging from the JWST Advanced Deep Extragalactic Survey (JADES) program. Photometric and spectroscopic followup with NIRCam and NIRSpec, respectively, confirm the redshift and yield UV-NIR light-curve, NIR color, and spectroscopic information all consistent with a Type Ia classification. Despite its classification as a likely SN Ia, SN 2023adsy is both fairly red (

) despite a host galaxy with low-extinction and has a high Ca II velocity (

km/s) compared to the general population of SNe Ia. While these characteristics are consistent with some Ca-rich SNe Ia, particularly SN 2016hnk, SN 2023adsy is intrinsically brighter than the low-
�
Ca-rich population. Although such an object is too red for any low-
�
cosmological sample, we apply a fiducial standardization approach to SN 2023adsy and find that the SN 2023adsy luminosity distance measurement is in excellent agreement (
≲

) with
Λ
CDM. Therefore unlike low-
�
Ca-rich SNe Ia, SN 2023adsy is standardizable and gives no indication that SN Ia standardized luminosities change significantly with redshift. A larger sample of distant SNe Ia is required to determine if SN Ia population characteristics at high-
�
truly diverge from their low-
�
counterparts, and to confirm that standardized luminosities nevertheless remain constant with redshift.

Magmatic iron-meteorite parent bodies are the earliest planetesimals in the Solar System,and they preserve information about conditions and planet-forming processes in thesolar nebula. In this study, we include comprehensive elemental compositions andfractional-crystallization modeling for iron meteorites from the cores of five differenti-ated asteroids from the inner Solar System. Together with previous results of metalliccores from the outer Solar System, we conclude that asteroidal cores from the outerSolar System have smaller sizes, elevated siderophile-element abundances, and simplercrystallization processes than those from the inner Solar System. These differences arerelated to the formation locations of the parent asteroids because the solar protoplane-tary disk varied in redox conditions, elemental distributions, and dynamics at differentheliocentric distances. Using highly siderophile-element data from iron meteorites, wereconstruct the distribution of calcium-aluminum-rich inclusions (CAIs) across theprotoplanetary disk within the first million years of Solar-System history. CAIs, the firstsolids to condense in the Solar System, formed close to the Sun. They were, however,concentrated within the outer disk and depleted within the inner disk. Future modelsof the structure and evolution of the protoplanetary disk should account for this dis-tribution pattern of CAIs.

The cost of acquiring information by natural selection
This is a short talk that I gave at the Banff International Research Station workshop on Modeling and Theory in Population Biology. The idea is to try to understand how the burden of natural selection relates to the amount of information that selection puts into the genome.
It's based on the first part of this research paper:
