FNRS 1 Balloon
Technical Data Sheet 1 FNRS 1 BALLOOn Balloon External diameter : 30 metres Payload : 1000 kg Materials : cotton and rubber Fuel : hydrogen Construction : Riedinger Ballon Fabrik (A), in 1931 The balloon was inflated with hydrogen, since the production of helium was too expensive in 1930. The diameter of the inflated balloon was 30 metres, its volume 14,130 m3. The balloon’s payload was 1000 kg and it was therefore clearly oversized in relation to the load to be carried. Its capacity theoretically enabled it to lift a locomotive! The balloon’s envelope consisted of two layers of cotton bonded by an intermediate layer of rubber. The fabric was dyed yellow (chloramine). This colour absorbs part of the sun’s blue, violet and ultraviolet rays. On take-off the balloon took the shape of a pear. It was only at altitude, when the pressure fell, that the balloon became spherical. Gondola External diameter : 2.10 metres Empty weight : 136 kg Crew : 2 men Endurance : 24 hours Thickness : 3.5 mm Materials : aluminium Portholes : glass Average on board temperature : -2 to + 40°C! Manufacturer of gondola : Georges L’Hoir, Liège (B) Interior equipment : Jacques Destappes, mechanic, Brussels (B) In structural terms, the sphere offers the highest volume for the smallest surface area, and therefore the lowest weight. The 2.10 metre diameter meanwhile, according to Auguste Piccard, is “(…) the smallest dimension in which two observers and a great deal of instrumentation can be accommodated”. The first gondola was painted in two colours. It was thus able to present a light or a dark side to the sun. -

Charting the cross-functional map between transcription factors and cancer metabolism Karin Ortmayr 1, Sébastien Dubuis 1 and Mattia Zampieri 1,* Affiliations: 1 Institute of Molecular Systems Biology, ETH Zurich, Auguste-Piccard-Hof 1, CH-8093 Zurich, Switzerland. *To whom correspondence should be addressed: [email protected] Abstract Transcriptional reprogramming of cellular metabolism is a hallmark feature of cancer. However, a systematic approach to study the role of transcription factors (TFs) in mediating cancer metabolic rewiring is missing. Here, we chart a genome-scale map of TF-metabolite associations in human using a new combined computational-experimental framework for large-scale metabolic profiling of adherent cell lines, and the integration of newly generated intracellular metabolic profiles of 54 cancer cell lines with transcriptomic and proteomic data. We unravel a large space of dependencies between TFs and central metabolic pathways, suggesting that the regulation of carbon metabolism in tumors may be more diverse and flexible than previously appreciated. This map provides an unprecedented resource to predict TFs responsible for metabolic transformation in patient-derived tumor samples, opening new opportunities in designing modulators of oncogenic TFs and in understanding disease etiology. Introduction Transcription factors (TFs) are at the interface between the cell’s ability to sense and respond to external stimuli or changes in internal cell-state1. -

Hugh Bradner's Development of the First Wet Suit
UC San Diego SIO Reference Title Wet Suit Pursuit: Hugh Bradner's Development of the First Wet Suit Permalink https://escholarship.org/uc/item/7353g3dj Author Rainey, Carolyn Publication Date 1998-11-01 eScholarship.org Powered by the California Digital Library University of California Wet Suit Pursuit: Hugh Bradner's Development of the First Wet Suit Carolyn Rainey Archives of the Scripps Institution of Oceanography University of California, San Diego La Jolla, CA 92093-0219 November 1998 SIO Reference Number 98-16 In the 100th anniversary issue of Sunset Magazine, published May 1998, the “ongoing timeline of major events” says that in 1952 UC Berkeley physicist Hugh Bradner invented the wet suit. This single fact summarizes a more complex story. In the spring of 1951 Bradner decided to spend some “weekend time” improving the equipment for the navy frogmen. Soon thereafter, he sent ideas and concepts of the wet suit to UC Berkeley physicist, Lauriston C. “Larry” Marshall, who was involved in a U.S. Navy/National Research Council Panel on Underwater Swimmers. In the fall of 1951 the effort to actively develop the wet suit began when colleagues at the Berkeley Radiation Lab joined Bradner in the fabrication and testing of various materials. At the end of 1949, the U.S. Marine Corps, U.S. Navy, and National Research Council agreed to work together using scientific applications to solve amphibious operational problems. A committee was formed under the chairmanship of UC Berkeley engineer Murrough P. “Mike” O’Brien. Several government panels met to discuss and watch East Coast and West Coast underwater demolition teams in action. -
May 2021 Newsletter Update
On March 10th, the FSU Great Give generated over $5,500 for the new FSUCML Diving Scholarship. In addition to funding generated through the Great Give, PADI, Aqua Lung and Divers Alert Network will provide support for the scholarship recipients in the form of certification materials, equipment, and diving accident insurance. A panel will be selecting the 2021 recipient this fall from a pool of deserving research-focused students. Preference will be given to students from historically underrepresented groups. If you know of someone that might be interested, please encourage them to apply. Summer research diving is underway with divers operating out of the FSU Marine Lab, the Florida Keys, and the Caribbean. The McCoy Lab began diving this week in Bonaire, becoming the first FSU dive team to work internationally since the Pandemic began. All divers using equipment from the Academic Diving Program will be using new Aqua Lung regulators. With funding provided by the Office of Research, ADP purchased twenty new Aqua Lung Core regulators with in-line i300C computers. Three new BARE dry suits and ten new Aqua Lung BCDs were also acquired including new Aqua Lung Soul BCDs - the first BCD in the dive locker that is designed for women. The 2021 Introduction to Scientific Diving course concluded on April 17th with divers-in-training punctuating their semester long training on a charter aboard the R/V Apalachee to K-Tower. This semester marked the first class to be taught as a credit course since 2017. Twelve divers successfully completed their AAUS certifications. The next training class is scheduled for spring 2022. -

By way of catching up, we have produced a Summer double issue and have the good fortune to be able to publish with a color cover. Coinciding with the Santa Barbara relocation is the appointment, by the Board of Directors, of the first members of the HDS USA Advisory Board. This distinguished group of senior diving professionals, with extensive backgrounds in diving medicine, technical development, commercial, military and sports diving, bring in excess of 300 years of diving experience to the Society. Most of their biographies are the size of town phone directories, and have had to be severely edited for publication. We are honored and gratefulfortheir willing offers of service, and hope that we have done their biographies justice. Details start on page 4. The recently introduced, Founding Benefactor class of membership has proven to be very popular with over half of the thirty available memberships already taken. An opportunity still exists to acquire one of these unique memberships and details of it's benefits are noted on page 9. On the international front, the ongoing formation of the HDS USA as a nonprofit corporation has, by law, changed the conditions that govern our relationship with the HDS in UK.
