Constraining the Environment of CH+ Formation with CH3+ Observations

The formation of CH+ in the interstellar medium has long been an outstanding problem in chemical models. In order to probe the physical conditions of the ISM in which CH+ forms, we propose the use of CH3+ observations. The pathway to forming CH3+ begins with CH+, and a steady state analysis of CH3+ and the reaction intermediary CH2+ results in a relationship between the CH+ and CH3+ abundances. This relationship depends on the molecular hydrogen fraction, f_H2, and gas temperature, T, so observations of CH+ and CH3+ can be used to infer the properties of the gas in which both species reside. We present observations of both molecules along the diffuse cloud sight line toward Cyg OB2 No. 12. Using our computed column densities and upper limits, we put constraints on the f_H2 vs. T parameter space in which CH+ and CH3+ form. We find that average, static, diffuse molecular cloud conditions (i.e. f_H2>0.2, T~60 K) are excluded by our analysis. However, current theory suggests that non-equilibrium effects drive the reaction C+ + H_2 --> CH+ + H, endothermic by 4640 K. If we consider a higher effective temperature due to collisions between neutrals and accelerated ions, the CH3+ partition function predicts that the overall population will be spread out into several excited rotational levels. As a result, observations of more CH3+ transitions with higher signal-to-noise ratios are necessary to place any constraints on models where magnetic acceleration of ions drives the formation of CH+.Comment: 7 pages, 3 figures, 2 tables, accepted for publication in Ap

Long-life mission reliability for outer planet atmospheric entry probes

The results of a literature analysis on the effects of prolonged exposure to deep space environment on the properties of outer planet atmospheric entry probe components are presented. Materials considered included elastomers and plastics, pyrotechnic devices, thermal control components, metal springs and electronic components. The rates of degradation of each component were determined and extrapolation techniques were used to predict the effects of exposure for up to eight years to deep space. Pyrotechnic devices were aged under accelerated conditions to an equivalent of eight years in space and functionally tested. Results of the literature analysis of the selected components and testing of the devices indicated that no severe degradation should be expected during an eight year space mission

POLICY, CULTURE, AND PEOPLE: A DIGITAL TRANSFORMATION STRATEGY FOR NAVSUP NOW AND IN THE FUTURE

The Naval Supply Systems Command is currently conducting an information technology modernization plan. Since the 2018 National Security Strategy was released, the U.S. has been in a declared state of great power competition with China and Russia. The nexus of great power competition and NAVSUP’s modernization arrive at digital transformation. The current threat environment for the U.S. military revolves around the idea that war will occur in all domains and for NAVSUP that means that logistics for U.S. forces will be contested. To help succeed in providing warfighters with the requirements they need, digital transformation at business levels such as NAVSUP need to be successful in order to increase the lethality of U.S. forces. Digital transformation is the act of using technology to improve processes, not just modernizing components of the information technology infrastructure. Through interviews with members of companies in the emerging technology sector and with members of NAVSUP, I garnered insights that I developed into recommendations on how NAVSUP can successfully conduct a digital transformation through innovation and education.Lieutenant Commander, United States NavyApproved for public release.

The designing and patenting of an improvement in hay tools

Citation: McCall, W. T. The designing and patenting of an improvement in hay tools. Senior thesis, Kansas State Agricultural College, 1908.Introduction: Few of the younger generation of today realize that practically every tool that is in present use on the farm is the product of the investitive genius of the past century. It is difficult for the average person to believe that the Machinery Age in which we are now living had its inception in times so recent as to be easily remembered by our grandparents or even by our parents

The Road Less Travelled: The Maine Energy Cost Reduction Act, Economic Federalism, and a Modern Approach to Preemption Analysis Under the Natural Gas Act of 1938

The saying “you can’t get there from here” is as authentically Maine as blueberries or lobster. Made famous in the mid-20th century by the storytelling troupe Bert and I, the colloquial phrase typifies the quirkiness and with that one often encounters north and east of the New Hampshire border. Despite the attempt at humor, the saying is apropos when one considers Maine’s position in both New England and the country. Being at the end of the line certainly has its advantages, among them being hundreds of square miles of untamed forest, and a bevy of natural resources that provide both sustenance and stunning vistas. However, isolation is a double-edge sword. For many years, Maine has struggled to revive a once vibrant manufacturing sector and following the “Great Recession” Maine’s economic growth has been sluggish, especially when compared to the rest of New England. In this struggle, the high price of energy, especially for industrial customers, has been a cause for concern. The recent closing of Verso’s paper mill in Bucksport, and the Chapter 11 bankruptcy filing of Great Northern Paper Company in Millinocket, with both companies blaming high energy costs as a precipitating factor in their demise, highlights the ongoing problem

Absorption Line Survey of H3+ toward the Galactic Center Sources III. Extent of the Warm and Diffuse Clouds

We present follow-up observations to those of Geballe & Oka (2010), who found high column densities of H3+ ~100 pc off of the Galactic center (GC) on the lines of sight to 2MASS J17432173-2951430 (J1743) and 2MASS J17470898-2829561 (J1747). The wavelength coverages on these sightlines have been extended in order to observe two key transitions of H3+, R(3,3)l and R(2,2)l, that constrain the temperatures and densities of the environments. The profiles of the H3+ R(3,3)l line, which is due only to gas in the GC, closely matches the differences between the H3+ R(1,1)l and CO line profiles, just as it does for previously studied sightlines in the GC. Absorption in the R(2,2)l line of H3+ is present in J1747 at velocities between -60 and +100 km/s. This is the second clear detection of this line in the interstellar medium after GCIRS 3 in the Central Cluster. The temperature of the absorbing gas in this velocity range is 350 K, significantly warmer than in the diffuse clouds in other parts of the Central Molecular Zone. This indicates that the absorbing gas is local to Sgr B molecular cloud complex. The warm and diffuse gas revealed by Oka et al. (2005) apparently extends to ~100 pc, but there is a hint that its temperature is somewhat lower in the line of sight to J1743 than elsewhere in the GC. The observation of H3+ toward J1747 is compared with the recent Herschel observation of H2O+ toward Sgr B2 and their chemical relationship and remarkably similar velocity profiles are discussed.Comment: 6 pages, 3 figures, 2 tables, Accepted for publication in Publications of the Astronomical Society of Japa
