JW Reason Family Science Extravaganza
IMPACT. 1: Support K-5 STEM education in the Hilliard school district. -- 2. Foster exploration of science, technology, engineering, and mathmatics as a shared experience between students and their family members. -- 3. Serve as a model for the diversity of genders, ethnicities, and races in STEM fields. Promote the fun of STEM exploration and investigation.OSU PARTNERS: NEURO (Neuroscience Education for Urban and Rural Outreach); OSU Kappa Phi Kappa Alpha Eta chapter; OSU Food Science Club; OSU Society of Women in Physics; OSU Women in Engineering; OSU Graduate Program in Genetic CounselingCOMMUNITY PARTNERS: Hilliard School System; JW Reason Elementary PTO; Columbus State Community; College; WBNS-TV; Nationwide Children's Hospital; NASA; COSI; Columbus Parks and Recreation Department; EvalSolutions Inc.PRIMARY CONTACT:Â Robert Pyatt ([email protected])Unlike other large cities, Columbus lacks a community science festival. Consequently, we have organized the JW Family Science Extravaganza as a proof-in-principle of such an event. Now in its fourth year, the JW Family Science Extravaganza is a satellite event of the USA Science and Engineering Festival. The event is held in an elementary school within the Hilliard City Schools district and features over twenty inquiry based activities for students and their families to explore

The ABC130 barrel module prototyping programme for the ATLAS strip tracker
For the Phase-II Upgrade of the ATLAS Detector, its Inner Detector,
consisting of silicon pixel, silicon strip and transition radiation
sub-detectors, will be replaced with an all new 100 % silicon tracker, composed
of a pixel tracker at inner radii and a strip tracker at outer radii. The
future ATLAS strip tracker will include 11,000 silicon sensor modules in the
central region (barrel) and 7,000 modules in the forward region (end-caps),
which are foreseen to be constructed over a period of 3.5 years. The
construction of each module consists of a series of assembly and quality
control steps, which were engineered to be identical for all production sites.
In order to develop the tooling and procedures for assembly and testing of
these modules, two series of major prototyping programs were conducted: an
early program using readout chips designed using a 250 nm fabrication process
(ABCN-25) and a subsequent program using a follow-up chip set made using 130 nm
processing (ABC130 and HCC130 chips). This second generation of readout chips
was used for an extensive prototyping program that produced around 100
barrel-type modules and contributed significantly to the development of the
final module layout. This paper gives an overview of the components used in
ABC130 barrel modules, their assembly procedure and findings resulting from
their tests.Comment: 82 pages, 66 figure
Identifying an indoor air exposure limit for formaldehyde considering both irritation and cancer hazards
Formaldehyde is a well-studied chemical and effects from inhalation exposures have been extensively characterized in numerous controlled studies with human volunteers, including asthmatics and other sensitive individuals, which provide a rich database on exposure concentrations that can reliably produce the symptoms of sensory irritation. Although individuals can differ in their sensitivity to odor and eye irritation, the majority of authoritative reviews of the formaldehyde literature have concluded that an air concentration of 0.3 ppm will provide protection from eye irritation for virtually everyone. A weight of evidence-based formaldehyde exposure limit of 0.1 ppm (100 ppb) is recommended as an indoor air level for all individuals for odor detection and sensory irritation. It has recently been suggested by the International Agency for Research on Cancer (IARC), the National Toxicology Program (NTP), and the US Environmental Protection Agency (US EPA) that formaldehyde is causally associated with nasopharyngeal cancer (NPC) and leukemia. This has led US EPA to conclude that irritation is not the most sensitive toxic endpoint and that carcinogenicity should dictate how to establish exposure limits for formaldehyde. In this review, a number of lines of reasoning and substantial scientific evidence are described and discussed, which leads to a conclusion that neither point of contact nor systemic effects of any type, including NPC or leukemia, are causally associated with exposure to formaldehyde. This conclusion supports the view that the equivocal epidemiology studies that suggest otherwise are almost certainly flawed by identified or yet to be unidentified confounding variables. Thus, this assessment concludes that a formaldehyde indoor air limit of 0.1 ppm should protect even particularly susceptible individuals from both irritation effects and any potential cancer hazard
Addressing the climate challenge
In 2021, colleagues from across the University of Birmingham community were invited to write articles about topics relevant to the COP26 climate change summit.
In this series of articles, experts from across many different disciplines provide new insight and evidence on how we might all understand and tackle climate change
