Dysfunctional Warfare: The Russian Invasion Of Ukraine, Rob Johnson

The US Army War College Quarterly: Parameters

Russia’s invasion of Ukraine was based on false premises, faulty assumptions, and a weak strategy. As the conflict has unfolded, heavy losses have imposed a strain on available Russian manpower. The Russian army reached a culminating point outside Kyiv and has exhibited little sign of operational learning. By contrast, Ukrainians have fought an existential war, making good use of dispersed light infantry tactics with high motivation levels. Western support has allowed them to compensate for their deficiencies in armaments and munitions. This commentary also shows military and policy leaders how the political context continues to impose limitations on the Ukrainians.

Rebuilding After Mass Furloughs, Michelle Price

Upstate New York Science Librarians Conference

During the summer of 2020, due to COVID-19 and preventative financial measures taken by the college, 70% of the library staff at St. John Fisher College were furloughed for approximately three months. This presentation is from the viewpoint of an employee who was furloughed and returned during wave one. What did the process of rebuilding look like? What words did we even use to describe what was happening?

Employees who were furloughed returned at three different time points, creating three waves. The library developed an on-boarding process to address policy and protocol changes and revised it to address emotional issues. …

Shifting A Culture, Ardeshir J. Arjomand

Communication Senior Capstones

What is popular culture and how does it influence us? How can we be more critically aware consumers of media messages? Are we always "online", or is there some way we can disconnect? These are the questions I've attempted to define through my research and experience studying contemporary "pop culture". Consider this a beginner’s guide on how to become aware of and deal with the constant bombardment of media messages, and how to become a filter for content, rather than a sponge. As critical consumers of media we can cater our consumption to better suit our needs and lifestyles. This …

Product Branching Fractions Of The Ch + Propene Reaction From Synchrotron Photoionization Mass Spectrometry, Adam J. Trevitt, Matthew B. Prendergast, Fabien Goulay, John D. Savee, David L. Osborn, Craig A. Taatjes, Stephen R. Leone

Adam Trevitt

The CH(X2Π) + propene reaction is studied in the gas phase at 298 K and 4 Torr (533.3 Pa) using VUV synchrotron photoionization mass spectrometry. The dominant product channel is the formation of C4H6 (m/z 54) + H. By fitting experimental photoionization spectra to measured spectra of known C4H6 isomers, the following relative branching fractions are obtained: 1,3-butadiene (0.63 ± 0.13), 1,2-butadiene (0.25 ± 0.05), and 1-butyne (0.12 ± 0.03) with no detectable contribution from 2-butyne. The CD + propene reaction is also studied and two product channels are observed that correspond to C4H6 (m/z 54) + D and C4H5D …

Pubertal Stage, Body Mass Index, And Cardiometabolic Risk In Children And Adolescents In Bogota, Colombia: The Cross-Sectional Fuprecol Study, Robinson Ramírez-Velez, Antonio García-Hermoso, Cesar A. Agostinis-Sobrinho, Jorge Mota, Rute Santos, Jorge Enrique Correa-Bautista, Carlos Andres Pena-Guzman, María Andrea Domínguez-Sanchez, Jacqueline Schmidt-Riovalle, Emilio Gonzalez-Jimenez

Faculty of Social Sciences - Papers (Archive)

This study explored the association between pubertal stage and anthropometric and cardiometabolic risk factors in youth. A cross-sectional study was conducted in 2877 Colombian children and adolescents (9¿17.9 years of age). Weight, height, and waist circumference were measured and body mass index (BMI) was calculated. A biochemical study was performed to determine the cardiometabolic risk index (CMRI). Blood pressure was evaluated and pubertal stage was assessed with the Tanner criteria. Hierarchical multiple regression analyses were performed. The most significant variable (p < 0.05) in the prognosis of cardiometabolic risk was found to be the BMI in both boys and girls. In the case of girls, the pubertal stage was also a CMRI predictive factor. In conclusion, BMI was an important indicator of cardiovascular risk in both sexes. Pubertal stage was associated with cardiovascular risk only in the girls.

Factors Governing Mass Transfer During Membrane Electrodialysis Regeneration Of Licl Solution For Liquid Desiccant Dehumidification Systems, Ali Hussein Al-Jubainawi, Zhenjun Ma, Yi Guo, Long D. Nghiem, Paul Cooper, Weihua Li

Faculty of Engineering and Information Sciences - Papers: Part A

This study investigates the mass transfer mechanisms and the performance of membrane electrodialysis (ED) for regenerating lithium chloride (LiCl) solution commonly used in liquid desiccant dehumidification systems. Experiments were conducted using an ED experimental system while numerical simulation was performed using COMSOL Multiphysics. The results showed that the water flux transfer due to osmosis and electro-osmosis during ED regeneration of LiCl liquid desiccant was significant and could not be ignored. The water flux due to osmosis and electro-osmosis is directly associated with the osmotic gradient and the applied current between the cathode and anode, respectively. The average flux of water …

A Contribution To Understanding The Impact Of Variations In Body Mass On Fractionating The Metabolic Burden Of Military Load Carriage, Heather Bowes, Catriona A. Burdon, Nigel A.S. Taylor

Faculty of Science, Medicine and Health - Papers: part A

Purpose: The oxygen cost associated with load carriage is dependent upon both its mass and its placement about the body. For occupations in which load carriage is routinely performed, and involves identical loads for all individuals, the relative metabolic cost varies inversely with body mass. However, whilst we understand the average impact of varying load placement, our appreciation of its impact on a morphologically diverse, contemporary workforce is very limited. Methods:The relationship between load placement and body mass was evaluated in 65 men (23.0 y [SD 3.0]; 80.5 kg [SD 1.7]: range 56.0-109.8 kg), matched for height-adjusted adiposity (59.3 mm …

Greenland Ice Sheet Mass Balance Reconstruction. Part I: Net Snow Accumulation (1600-2009), Jason E. Box, Noel Cressie, David H. Bromwich, Ji-Hoon Jung, Michiel Van Den Broeke, J H. Van Angelen, Richard R. Forster, Clement Miege, Ellen Mosley-Thompson, Bo Vinther, Joseph R. Mcconnell

Professor Noel Cressie

Ice core data are combined with RACMO2 regional climate model (RCM) output (1958-2010) to develop a reconstruction of the Greenland ice sheet net snow accumulation rate (Ât(G)) spanning years 1600-2009. Regression parameters from RCM output regressed on 86 ice cores are used with available cores in a given year resulting in the reconstructed values. Each core site’s residual variance is used to inversely weight the cores’ respective contributions. The interannual amplitude of the reconstructed accumulation rate is damped by the regressions and is thus calibrated to match that of the RCM data. Uncertainty and significance of changes is measured using …

Personality And Body-Mass-Index In School-Age Children: An Exploration Of Mediating And Moderating Variables, Mark S. Allen, Stewart A. Vella

Faculty of Social Sciences - Papers (Archive)

This study explored longitudinal associations between personality and body-mass-index (BMI) in school-age children, including the potential mediating role of screen time and physical activity, and the potential moderating roles of child demographics and neighbourhood socioeconomic position. Participants were the parents (and teachers) of 3857 ten-year-old children, who completed questionnaires at baseline with a two-year follow-up. After controlling for child demographics (e.g., sex, pubertal status), we found that personality was unimportant for concurrent BMI, but was important for subsequent BMI and change in BMI over two years. Low levels of introversion and persistence at baseline, and decreases in persistence over time, …

Determination Of Stress State In Rock Mass Using Strain Gauge Probes Ccbo, Petr Waclawik, Stas Lubomir, Jan Nemcik, Petr Konicek, Tomas Kalab

Faculty of Engineering and Information Sciences - Papers: Part A

The strain gauge probes of different construction are typically used for determination of stress state rock mass. The modified overcoring method known as the Compact Conical ended Borehole Overcoring method (CCBO) for stress state determination in rock mass was designed in Institute of Geonics of the CAS (IGN) in cooperation with Kumamoto University in Japan. The implemented adjustment of the overcoring method consists mainly in omitting the overcoring phase (stress relief phase). The probe is glued directly to the conically shaped end of a borehole. The data logger located within the conical probe enables continual strain monitoring directly in the …

Using a sample of 98 galaxy clusters recently imaged in the near-infrared with the European Southern Observatory (ESO) New Technology Telescope, WIYN telescope and William Her- schel Telescope, supplemented with 33 clusters from the ESO archive, we measure how the stellar mass of the most massive galaxies in the universe, namely brightest cluster galaxies (BCGs), increases with time. Most of the BCGs in this new sample lie in the redshift range 0.2

Lean Body Mass Associated With Upper Body Strength In Healthy Older Adults While Higher Body Fat Limits Lower Extremity Performance And Endurance, Karen E. Charlton, Marijka Batterham, Kelly Langford, Jenna Lateo, Erin Brock, Karen L. Walton, Philippa M. Lyons-Wall, Katie Eisenhauer, Nick Green, Cameron Mclean

Dr Marijka Batterham

Impaired strength adversely influences an older person's ability to perform activities of daily living. A cross-sectional study of 117 independently living men and women (age = 73.4 9.4 year; body mass index (BMI) = 27.6 4.8 kg/m2) aimed to assess the association between body composition and: (1) upper body strength (handgrip strength, HGS); (2) lower extremity performance (timed up and go (TUG) and sit to stand test (STS)); and (3) endurance (6-minute walk (SMWT). Body composition (% fat; lean body mass (LBM)) was assessed using bioelectrical impedance. Habitual physical activity was measured using the Minnesota Leisure Time Physical Activity Questionnaire …

Getting Bigger, Quicker? Gendered Socioeconomic Trajectories In Body Mass Index Across The Adult Lifecourse: A Longitudinal Study Of 21,403 Australians, Xiaoqi Feng, Andrew Wilson

Faculty of Social Sciences - Papers (Archive)

Do socioeconomic inequities in body mass index (BMI) widen across the adult lifecourse? BMI data for 29,104 male and 32,454 female person-years aged 15 years and older (21,403 persons in total) were extracted from the Household, Income and Labour Dynamics in Australia between 2006 and 2012. Multilevel linear regression was used to examine age and gender specific trajectories in BMI by quintiles of neighborhood socioeconomic circumstance. Models were adjusted for probable sources of confounding, including couple status, number of children resident, if somebody in the household had been pregnant in the last 12 months, the highest level of education achieved, …

Organic Geochemistry Of Non-Marine Permian-Triassic Mass Extinction (Ptme) Sections In The Sydney Basin, Australia, Simon George, Megan L. Williams, Justine Wheeler, Shirin Baydjanova, Nathan Camilleri, Benjamin Hanssen, Regina Maher, Uvana Meek, Adrian Nelson, Caiden O'Connor, William Porter, Brian G. Jones

Faculty of Science, Medicine and Health - Papers: part A

Most organic geochemical studies of the Permian-Triassic mass extinction (PTME) have utilised marine sections, and the boundary is readily identified by a negative carbon isotope excursion. It is now well understood from various locations around the world that the marine ecosystem collapse is accompanied by biomarker evidence for photic zone euxinia, including isorenieratane, crocetane and 2,3,6-aryl isoprenoids (e.g. Grice et al., 2005). Far fewer studies have been carried out on non-marine PTME sections, and in particular no biomarker studies have been carried out on Australian sections, despite there being extensive Permian and Triassic sequences in eastern Australia, notably in the …

Novel Experimental Setup For Time-Of-Flight Mass Spectrometry Ion Detection In Collisions Of Anionic Species With Neutral Gas-Phase Molecular Targets, J C. Oller, L Ellis-Gibbings, F Ferreira Da Silva, Paulo Limao-Vieira, Gustavo Garcia

Faculty of Engineering and Information Sciences - Papers: Part A

We report a novel experimental setup for studying collision induced products resulting from the interaction of anionic beams with a neutral gas-phase molecular target. The precursor projectile was admitted into vacuum through a commercial pulsed valve, with the anionic beam produced in a hollow cathode discharge-induced plasma, and guided to the interaction region by a set of deflecting plates where it was made to interact with the target beam. Depending on the collision energy regime, negative and positive species can be formed in the collision region and ions were time-of-flight (TOF) mass-analysed. Here, we present data on O-2 precursor projectile, …

Infrared Imaging As A Non-Invasive Tool For Documenting Maggot Mass Temperatures, Aidan P. Johnson, James F. Wallman

Faculty of Science, Medicine and Health - Papers: part A

Forensic entomology relies on the ability to predict the temperatures to which maggots have been exposed, due to the resultant impact on their growth rate. Mercury thermometers and electrical temperature sensors have traditionally been used to record temperatures of maggot masses, cadavers and the surrounding soil and air. However, these techniques are limited to one measurement at a time and thus may not accurately describe the complexities of the thermal environment of the cadaver. Infrared imaging has gained increasing popularity because of its resolution, affordability and portability. Using decomposing pig carcasses, the current study showed that surface temperature measurements recorded …

Ambient Ionisation Mass Spectrometry For The Characterisation Of Polymers And Polymer Additives: A Review, Martin R. L Paine, Philip J. Barker, Stephen J. Blanksby

Faculty of Science, Medicine and Health - Papers: part A

The purpose of this review is to showcase the present capabilities of ambient sampling and ionisation technologies for the analysis of polymers and polymer additives by mass spectrometry (MS) while simultaneously highlighting their advantages and limitations in a critical fashion. To qualify as an ambient ionisation technique, the method must be able to probe the surface of solid or liquid samples while operating in an open environment, allowing a variety of sample sizes, shapes, and substrate materials to be analysed. The main sections of this review will be guided by the underlying principle governing the desorption/extraction step of the analysis; …

Desorption Electrospray Ionisation Mass Spectrometry Of Stabilised Polyesters Reveals Activation Of Hindered Amine Light Stabilisers, Martin R.L Paine, Ganna Gryn'ova, Michelle L. Coote, Philip J. Barker, Stephen J. Blanksby

Faculty of Science, Medicine and Health - Papers: part A

The use of hindered amine light stabilizers (HALS) to retard thermo- and photo-degradation of polymers has become increasingly common. Proposed mechanisms of polymer stabilisation involve significant changes to the HALS chemical structure; however, reports of the characterisation of these modified chemical species are limited. To better understand the fate of HALS and determine their in situ modifications, desorption electrospray ionisation mass spectrometry (DESI-MS) was employed to characterise ten commercially available HALS present in polyester-based coil coatings. TINUVIN® 770, 292, 144, 123, 152, and NOR371; HOSTAVIN® 3052, 3055, 3050, and 3058 were separately formulated with a pigmented, thermosetting polyester resin, cured …

Average Mass Scan Of The Total Ion Chromatogram Versus Percentage Chemical Composition In Multivariate Statistical Comparison Of Complex Volatile Mixtures, Niko Radulovic, Polina Blagojevic, Danielle Skropeta

Danielle Skropeta

The analysis of complex volatile mixtures by gas chromatography-mass spectrometry (GC-MS) is a time-consuming process. It involves separation and identification of the components based on their retention times and fragmentation patterns, followed by determination of their relative percentages from integration of their peak areas. Herein we show that multivariate statistical analysis of the relative abundances of the m/z values obtained from the average mass scans (AMS) of the complex mixture is a faster and potentially more reliable method of assessing these mixtures. To achieve this, 15 model complex mixtures, were prepared comprising varying amounts of 10 different constituents. The AMS …

Rapid Differentiation Of Isomeric Lipids By Photodissociation Mass Spectrometry Of Fatty Acid Derivatives, Huong T. Pham, Adam J. Trevitt, Todd W. Mitchell, Stephen J. Blanksby

Adam Trevitt

RATIONALE Both traditional electron ionization and electrospray ionization tandem mass spectrometry have demonstrated limitations in the unambiguous identification of fatty acids. In the former case, high electron energies lead to extensive dissociation of the radical cations from which little specific structural information can be obtained. In the latter, conventional collision-induced dissociation (CID) of even-electron ions provides little intra-chain fragmentation and thus few structural diagnostics. New approaches that harness the desirable features of both methods, namely radical-driven dissociation with discrete energy deposition, are thus required. METHODS Herein we describe the derivatization of a structurally diverse suite of fatty acids as 4-iodobenzyl …

Differentiation Of Complex Lipid Isomers By Radical-Directed Dissociation Mass Spectrometry, Huong Pham, Tony Ly, Adam Trevitt, Todd Mitchell, Stephen Blanksby

Adam Trevitt

Contemporary lipidomics protocols are dependent on conventional tandem mass spectrometry for lipid identification. This approach is extremely powerful for determining lipid class and identifying the number of carbons and the degree of unsaturation of any acyl-chain substituents. Such analyses are however, blind to isomeric variants arising from different carbon−carbon bonding motifs within these chains including double bond position, chain branching, and cyclic structures. This limitation arises from the fact that conventional, low energy collision-induced dissociation of even-electron lipid ions does not give rise to product ions from intrachain fragmentation of the fatty acyl moieties. To overcome this limitation, we have …

Uv Photodissociation Action Spectroscopy Of Haloanilinium Ions In A Linear Quadrupole Ion Trap Mass Spectrometer, Christopher S. Hansen, Benjamin B. Kirk, Stephen J. Blanksby, Richard A. J O'Hair, Adam J. Trevitt

Adam Trevitt

UV-vis photodissociation action spectroscopy is becoming increasingly prevalent because of advances in, and commercial availability of, ion trapping technologies and tunable laser sources. This study outlines in detail an instrumental arrangement, combining a commercial ion-trap mass spectrometer and tunable nanosecond pulsed laser source, for performing fully automated photodissociation action spectroscopy on gas-phase ions. The components of the instrumentation are outlined, including the optical and electronic interfacing, in addition to the control software for automating the experiment and performing online analysis of the spectra. To demonstrate the utility of this ensemble, the photodissociation action spectra of 4-chloroanilinium, 4-bromoanilinium, and 4-iodoanilinium cations …

Branching Fractions Of The Cn + C3h6 Reaction Using Synchrotron Photoionization Mass Spectrometry: Evidence For The 3-Cyanopropene Product, Adam Trevitt, Talitha Selby, Craig Taatjes, Satchin Soorkia, J Savee, D L Osborn, S R Leone

Adam Trevitt

The gas-phase CN + propene reaction is investigated using synchrotron photoionization mass spectrometry (SPIMS) over the 9.8 - 11.5 eV photon energy range. Experiments are conducted at room temperature in 4 Torr of He buffer gas. The CN + propene addition reaction produces two distinct product mass channels, C3H3N and C4H5N, corresponding to CH3 and H elimination, respectively. The CH3 and H elimination channels are measured to have branching fractions of 0.59 + 0.15 and 0.41 + 0.10, respectively. The absolute photoionization cross sections between 9.8 and 11.5 eV are measured for the three considered H-elimination coproducts: 1-, 2-, and …
