description: As intra-party disagreements rise, primary challenges between candidates with ideological differences occur. A deeper understanding of how these primary challenges affect party success will assist potential candidates, and the parties themselves, in making safer and more helpful decisions in their pursuit to change platforms and policies. This thesis attempts to study the effect of contested primary elections between ideologically distanced candidates on their party’s general election success. Merging three existing datasets, I use a custom dataset with candidate-level data from 1980-2016. I employ several fixed-effect multivariate regression models measuring the effect of ideological difference in a primary race (utilizing CFscores as an ideological marker) and the closeness of the primary race itself on the general election vote percentage of the respective political party. I am unable to find a relationship between these variables measured in an interaction, nor am I able to find a relationship between ideological distance in a primary and any effect on general election vote percentage. I do measure a positive correlation between the closeness of a primary race, and the general election vote percentage for the respective primary winner; the less competitive the primary election is, the better the candidate performs in the general election. I conclude that the data utilized are robust in their ideological mapping, however, current ideological scores (CFscore and DW-NOMINATE) are insufficient in measuring extremism as a variable. Further research within this theoretical framework ought to attempt a measurement of political extremism, rather than ideological differences measured in relation to their respective party members.

The Manix Beds were deposited in a Pleistocene lake basin that occupied 200 to 300 square miles of the Mojave Desert, near the center of San Bernardino County, California. Three stages of lake deposition are recognized. Arenaceous clays and argillaceous sands, light grayish-green in color, are the predominant lithologies. The first and second lake stages are separated by interpluvial sediments; erosion occurred between the second and third stages. The total thickness of lake and interpluvial deposition in the center of the basin probably exceeded 250 feet. Except for minor faulting, which has affected even the youngest layers, the Manix Beds are essentially undeformed.

When Lake Manix first formed, the mammalian fauna included a sabre-tooth cat apparently close to Machairodus, Equus sp. cf. E. scotti, Camelops sp. cf. C. kansanus, a giant camel, and possibly a primitive species of Tremarctotherium. Therefore, an Illinoian age is suggested for the first lake stage. Tortoise and fish remains tend to corroborate this dating. This pluvial stage may be younger, but hardly older, than Illinoian as is indicated by fragmentary remains of what appears to be a small or medium-sized Bison. The Avifauna indicates a late Pleistocene, possibly Tahoe, age for the second lake stage. The molluscan fauna from this lake is possibly of Tahoe times. No vertebrate fossils have been recovered from beds of the third lake stage, but, sequentially, deposition probably took place during the Tioga subage of the Wisconsin.

Conformable beneath the Manix Beds are 300 to 400 feet of fanglomerates that are considered to be interpluvial sediments of probable Yarmouthian age. The fanglomerates overlie, with an angular unconformity, Tertiary volcanics that have been highly sheared and deformed, probably by Pasadenan orogenic movements. The extreme coarseness, angularity, and lack of decomposition or sorting of the fanglomerates suggest their deposition during the late phases of the Pasadenan Orogeny in the Yarmouthian interglacial age.

description: We have measured the interlayer thermal conductivity of crystals of the organic semiconductor rubrene, using ac-calorimetry. Since ac-calorimetry is most commonly used for measurements of the heat capacity, we include a discussion of its extension for measurements of the transverse thermal conductivity of thin crystals of poor thermal conductors, including the limitations of the technique. For rubrene, we find that the interlayer thermal conductivity, 0.7 mW/cm K, is several times smaller than the (previously measured) in-layer value, but its temperature dependence indicates that the interlayer mean free path is at least a few layers.

Communication in public health

description: Introduction: As a global health crisis, COVID-19 has disproportionately affected various aspects of life. Unlike previous global pandemics, individuals nowadays are more interconnected with instantaneous access to a flow of information, including access to social media. Risk communication is one of the key pillars of outbreak communication, which requires an in-depth understanding of key groups and stakeholders to ensure effective risk communication responses to the COVID-19 pandemic. Social media can be useful for risk communication as it allows both experts and the public to quickly spread and gather information, however, it can also be detrimental as it generates widespread fear and misinformation. Objective: This thesis aims to analyze the use of social media for risk communication during COVID-19. This includes how different types of organizations have been using social media, key trends of social media campaigns, lessons learned, and actionable suggestions to effectively utilize social media for risk communication. Methods: A literature search was conducted starting in February 2020. The search was limited to articles published from January 1 to December 31, 2020 in PubMed, Scopus, Embase, and Web of Science to identify relevant articles to be included in the analysis. Only articles in English are included in the review. Results: Based on the inclusion and exclusion criteria, 26 articles met the criteria of the review. The majority of the studies discuss the use of social media for risk communication of COVID-19 among government leaders and agencies, with a total of 16 studies retrieved. Most studies analyze the use of Twitter, followed by Facebook and local social media platforms. The frequency of posting and message trends highly correspond to the stages of the pandemic and related risk perception. Conclusion: The pandemic has further elucidated the need for clear communication between stakeholders and the public in response to a public health emergency. This study has shown that government agencies are important stakeholders in risk communication on social media. News media companies and outlets, healthcare organizations, healthcare professionals, transportation services, celebrities, influencers, and youth groups are also among the most prominent stakeholders in COVID-19 risk communication on social media. Insufficiency, incongruency, and inconsistency across critical message types in communicating COVID-19 were prevalent in social media. This should further be improved to optimize potential public health communication strategies on social media.

description: Given the scarcity of COVID-19 vaccines, equitable (fair) allocation of limited vaccines across the main administrative units of a country (e.g. municipalities) has been an important concern for public health authorities worldwide. In this study, we address the equitable allocation of the COVID-19 vaccines inside countries by developing a novel, evidence-based mathematical model that accounts for multiple priority groups (e.g. elderly, healthcare workers), multiple vaccine types, and regional characteristics (e.g. storage capacities, infection risk levels). Our research contributes to the literature by developing and validating a model that proposes equitable vaccine allocation alternatives in a very short time by (a) minimising deviations from the so-called ‘fair coverage’ levels that are computed based on weighted pro-rata rations, and (b) imposing minimum coverage thresholds to control the allocation of vaccines to higher priority groups and regions. To describe the merits of our model, we provide several equity and effectiveness metrics, and present insights on different allocation policies. We compare our methodology with similar models in the literature and show its better performance in achieving equity. To illustrate the performance of our model in practice, we perform a comprehensive numerical study based on actual data corresponding to the early vaccination period in Turkey.

description: Workload consolidation, sharing physical resources among multiple workloads, is a promising technique to save cost and energy in cluster computing systems. This paper highlights a few challenges of workload consolidation for Hadoop as one of the current state-of-the-art data-intensive cluster computing system. Through a systematic step-by-step procedure, we investigate challenges for efficient server consolidation in Hadoop environments. To this end, we first investigate the inter-relationship between last level cache (LLC) contention and throughput degradation for consolidated workloads on a single physical server employing Hadoop distributed file system (HDFS). We then investigate the general case of consolidation on multiple physical servers so that their throughput never falls below a desired/predefined utilization level. We use our empirical results to model consolidation as a classic two-dimensional bin packing problem and then design a computationally efficient greedy algorithm to achieve minimum throughput degradation on multiple servers. Results are very promising and show that our greedy approach is able to achieve near optimal solution in all experimented cases.

The following intervention proposal includes an initial needs assessment, intervention materials, implementation plan, and evaluation plan guided by public health theory and practice to effectively implement and maintain the Peers for Equity and Eradicating Racism (PEER) program.
title: Cuticular hydrocarbons in ants (Hymenoptera: Formicidae) and other insects: how and why they differ among individuals, colonies, and species

description: The body surface of nearly all insects, including ants, is covered with a lipid layer that largely consists of cuticular hydrocarbons (CHC). They fulfil several functions, the two best-studied ones being communication and protection against water loss. CHC profiles are astonishingly diverse as even a single individual can possess more than 100 different hydrocarbon molecules. Species vastly differ in their CHC composition, but also within species, CHC profiles vary among individuals of different sex, caste, fertility, age, health state, etc. This variation has been intensely studied especially in eusocial insects like ants, where differences are likely to have a signalling function. However, with so many sources of variation in CHC profiles, it is easy to lose track of which factors are more important than others, which patterns can be generalised, and which are idiosyncratic. Thus, we need a deeper understanding of how precisely different factors influence CHC variation. In this review, we aim to provide an overview of what is known to date about fixed and plastic CHC variation and discuss sources of variation on the level of individuals, social insect colonies, populations, and species. We focus on abiotic and biotic environmental factors, social structure and the genetic background as sources of CHC variation. Finally, we discuss how variation can be adaptive and how it can be constrained by biophysical and biosynthetic mechanisms. Focusing on clearly defined CHC traits will help us to build a predictive framework to understand how CHC profiles are shaped by multiple selection pressures, to identify how different sources affect fixed and plastic CHC variation, and to determine the adaptive value of CHC traits.

description: The electronic structure and magnetic properties of pure and doped {Fe$_{16}$N$_2$} systems have been studied in the local-density (LDA) and quasiparticle self-consistent {\emph{GW}} approximations. The {\emph{GW}} magnetic moment of pure {Fe$_{16}$N$_2$} is somewhat larger compared to LDA but not anomalously large. The effects of doping on magnetic moment and exchange coupling were analyzed using the coherent potential approximation. The theoretical Curie temperature in pure {Fe$_{16}$N$_2$} is significantly higher than the measured value, which is attributed to the quality of available samples and the interpretation of experimental results. We found that different Fe sites contribute very differently to the magnetocrystalline anisotropy energy (MAE), which offers a way to increase MAE by small additions of Co or Ti. MAE also increases under tetragonal strain.

description: The poorly resolved pathway of the sub-thermocline waters (>300 m) within the Makassar Strait, the primary inflow path of the Indonesian Throughflow, is investigated using in situ mooring measurements and Argo profiles at the entrance to the Indonesian Seas. We focus on the strong subthermocline intrusion in the summer of 2016, when significant changes of sub-thermocline transport thrice as large as the interannual standard deviation occurred. Analysis suggests that the intrusion was drawn from the North Equatorial Subsurface Current (NESC) flowing westward below the North Equatorial Countercurrent, which was composed of a mixture of intermediate-depth waters from both the North and South Pacific. The anomalously strong NESC to the Makassar sub-thermocline in the summer 2016 is suggested to be in response to the 2015/2016 extreme El Niño event, forced by the trade wind anomalies over the western-central Pacific Ocean through westward and downward propagating baroclinic Rossby wave

description: Drift is a significant issue that undermines the reliability of gas sensors. This paper introduces a probabilistic model to distinguish between environmental variation and instrumental drift, using low-cost non-dispersive infrared (NDIR) CO2 sensors as a case study. Data from a long-term field experiment is analyzed to evaluate both sensor performance and environmental changes over time. Our approach employs importance sampling to isolate instrumental drift from environmental variation, providing a more accurate assessment of sensor performance. The results show that failing to account for environmental variation can significantly affect the evaluation of sensor drift, leading to improper calibration processes.

description: Achieving effective locomotion on diverse terrestrial substrates can require subtle changes of limb kinematics. Biologically inspired legged robots (physical models of organisms) have shown impressive mobility on hard ground but suffer performance loss on unconsolidated granular materials like sand. Because comprehensive limb-ground interaction models are lacking, optimal gaits on complex yielding terrain have been determined empirically. To develop predictive models for legged devices and to provide hypotheses for biological locomotors, we systematically study the performance of SandBot, a small legged robot, on granular media as a function of gait parameters. High performance occurs only in a small region of parameter space. A previously introduced kinematic model of the robot combined with a new anisotropic granular penetration force law predicts the speed. Performance on granular media is maximized when gait parameters minimize body acceleration and limb interference, and utilize solidification features of granular media.
Hagar and Sarah and Mary and Elizabeth: Reading Luke 1 with Genesis 16/21

description: This paper undertakes an intertextual reading of Luke 1 through the lens of the Hagar stories. We find there are parallel characters which sometimes cross over each other, and echoes of the Genesis text in the Lukan story. Examining the texts closely helps peel away some of the history of interpretation around Hagar and around Mary, to perceive parts of each story that are often downplayed. There is a temptation to tie up the conflict between Hagar and Sarah in the affirmation and closeness of Mary and Elizabeth, but this paper does not find the Lukan text to be a reconciliation text, and pushes back on the reader's desire to make hard stories better.

A heterodyne frequency-beat measurement and a Fabry Perot interferometer have been applied to analyze the side-band generation with different experimental parameters, such as frequency difference, injection laser power and tapered amplifier current. In laser cooling potassium40 and potassium41 with hyperfine splitting of 1.3GHz and 254MHz, respectively, the side-band generation with a small frequency difference has a significant effect on the number of trapped atoms.

description: Around 30,000 Afghans have been denied protection in Germany and are categorised as ausreisepflichtig (required to leave the country). Of these, just over 1,000 people have been removed over the four years that removals were implemented, and that at extraordinary costs. For all who are categorised as ‘deportable’, this was a constant source of fear and insecurity – never knowing who would be next on the list. This article outlines the German politics behind the deportation of Afghans, with a focus on the years 2016–2021. It argues that deportations have become a significant element of the ‘border spectacle’ (De Genova 2013), staging a drama of exclusion that affirms the national order of being. I frame the deportation spectacle as a part of German biopolitics. According to Foucault, biopolitics is about ‘to make live and to let die’. Whilst biopolitical perspectives mostly focus on ‘make live’, I argue that deportations are part of the inevitable dark side of biopolitics pointed out by Foucault: that of letting di

These operators can be viewed as random operators on the Bethe strip, a graph (lattice) with loops.

Фитомасса древостоев оценена по модельным деревьям с учетом типов их развития (по оригинальной классификации). Определены содержание и запасы углерода и азота в фитомассе, подстилке и почве. Установлено, что фитомасса дубрав ниже, чем до периода усыхания дуба (в 1970-х - начале 1980-х гг.) в аналогичных насаждениях. Масса листового опада и подстилки соответствует прежним величинам за счет развития нижних древесных ярусов. Изученные дубравы наиболее различаются по запасам углерода и азота в фитомассе, значительно меньше - по их запасам в почве, ёмкости и скорости ежегодного круговорота. Содержание углерода, азота и неструктурных углеводов в органах дуба в этих дубравах сходно.

description: The Irish Sea basin forms a distinct node of histories, economies, and identities. The Ports, Past and Present project considered five very different ports and their communities on either side of the sea: Dublin, Rosslare, Holyhead, Fishguard and Pembroke Dock. This is the redacted and abridged business plan for the project, which ran 2019-23. Executive Summary
 The ultimate changes sought and the final outcomes for the Ports, Past and Present project are:
 • Coastal communities enjoy an increased awareness of their cultural heritage and develop new opportunities for heritage tourism.
 • Port towns become ‘stopping places’ and ‘spending places’ rather than just ‘through places’ for tourists, with an increase in tourism-related employment
 • Tourism Networks are formed between twinned Irish and Welsh ports, linking local authorities, tourism-related SMEs, community organisations and creative individuals on both sides of the Irish Sea.

description: Alzheimer's disease and related dementias (ADRDs) are a global crisis facing the aging population and society as a whole. With the numbers of people with ADRDs predicted to rise dramatically across the world, the scientific community can no longer neglect the need for research focusing on ADRDs among underrepresented ethnoracial diverse groups. The Alzheimer's Association International Society to Advance Alzheimer's Research and Treatment (ISTAART; alz.org/ISTAART) comprises a number of professional interest areas (PIAs), each focusing on a major scientific area associated with ADRDs. We leverage the expertise of the existing international cadre of ISTAART scientists and experts to synthesize a cross-PIA white paper that provides both a concise “state-of-the-science” report of ethnoracial factors across PIA foci and updated recommendations to address immediate needs to advance ADRD science across ethnoracial populations.

description: We consider the elliptic system of linear elasticity with bounded measurable coefficients in a domain where the second Korn inequality holds. We construct heat kernel of the system subject to Dirichlet, Neumann, or mixed boundary condition under the assumption that weak solutions of the elliptic system are Hölder continuous in the interior. Moreover, we show that if weak solutions of the mixed problem are Hölder continuous up to the boundary, then the corresponding heat kernel has a Gaussian bound. In particular, if the domain is a two dimensional Lipschitz domain satisfying a corkscrew or non-tangential accessibility condition on the set where we specify Dirichlet boundary condition, then we show that the heat kernel has a Gaussian bound. As an application, we construct Green's function for elliptic mixed problem in such a domain.

description: Проведен анализ распространения видов сосудистых растений, участвующих в сложении высокогорных сообществ с участием звездчатки подушечниковой ( Stellaria pulvinata Grub.), которые формируют самостоятельный высотный пояс в высотно-поясном спектре растительности аридного класса типов поясности в центральной части Монгольского Алтая (2700-3300 м н.у.м. БС). Выявлены ценотически активные виды ценофлор криофитных степей и криофитноразнотравных подушечников, к которым относятся самобытные элементы крио-ксерофитных условий ( Oxytropis oligantha , O. chionophylla , Saussurea leucophylla , Chamaerhodos altaica, Arenaria meyeri, Androsace septentrionalis ), монтанные виды с приуроченностью к высокогорным районам Южной Сибири и Центральной Азии ( Festuca kryloviana, Poa altaica ), а также дерновинные злаки, представленные типично степными видами с широким распространением ( Festuca lenensis, Koeleria cristata ). С помощью моделирования пространственного распространения показано, что эколого-ценотический оптимум большинства видов расположен вне области развития криофитных степей и подушечников региона. В соответствии с выявленными потенциальными ареалами видов, ценотически сопряженных со Stellaria pulvinata , определены тесные связи растительного покрова высокогорий Центрального Монгольского Алтая с горами Южной Сибири.
An experimental investigation of flame propagation downstream of a cylindrical flameholder

Subjects: Aeronautics

description: Flame propagation downstream of a 1/8 inch circular cylindric flameholder was studied experimentally.  The effects on flame spreading of the fuel-air mixture velocity and such chemical parameters as fuel-air ratio, mixture temperature, and fuel composition were determined. Combustion wake widths were determined from measurement of spark Schlieren photographs.

The data indicate that flow was laminar up to a critical velocity corresponding to a Reynolds number of 0.9 x 10^4, and turbulent for super critical velocities.  The experiments were restricted to the turbulent flow regime.  In this regime, the wake width was velocity independent and fuel-air ratio had only a slight effect.  There was a small, and nearly linear, decrease in wake width as the temperature was increased.  The effect substitution of hydrogen gas for hydrocarbon fuel revealed that turbulent wake spreading was independent of fuel composition.

Comparison of the experimental results with theoretical treatments of flame spreading showed that none of the existing theories was satisfactory.

description: Appendicularian tunicates are some of the most abundant mesozooplankton organisms with key roles in marine trophic webs and global carbon flux. Like most appendicularians with cosmopolitan distributions, Oikopleura dioica Fol, 1872 is considered a single species worldwide based on morphological features that distinguish them from other appendicularians. Despite their abundance, however, there are still only ~ 70 described appendicularian species, compared to over 2800 ascidian tunicates. Here we perform a molecular phylogenetic, morphological, and reproductive assessment of O. dioica specimens collected from the Ryukyu Archipelago, mainland Japan, and Europe. The specimens are morphologically very similar, with only detailed examination of the oikoplastic epithelium and quantitative measurements revealing minor distinguishing characteristics. Phylogenetic analyses of the ribosomal gene loci and mitochondrial cytochrome oxidase I (COI) gene strongly indicate that they form three separate genetic clades despite their morphological similarities. Finally, in vitro crosses between the Ryukyu and mainland Japanese specimens show total prezygotic reproductive isolation. Our results reveal that the current taxonomic O. dioica classification likely hides multiple cryptic species, highlighting the genetic diversity and complexity of their population structures. Cryptic organisms are often hidden under a single species name because their morphological similarities make them difficult to distinguish and their correct identification is fundamental to understanding Earth’s biodiversity. O. dioica is an attractive model to understand how morphological conservation can be maintained despite pronounced genetic divergence.

description: We propose a simple extension to the Standard Model, wherein neutrinos naturally attain small Majorana masses through a one-loop radiative mechanism featuring particles within the loops characterized by milli-charges. Unlike the conventional scotogenic model, our approach avoids imposing a discrete symmetry or expanding the gauge sector. The minuscule electric charges ensure the stability of the lightest particle within the loop as a viable dark matter candidate. Our investigation systematically scrutinizes the far-reaching phenomenological implications arising from these minuscule charges.

description: In den letzten Jahren gewinnen Unterrichtsthemen zu Renaissance und Humanismus im Lateinunterricht zunehmend an Bedeutung. Zahlreiche Lektürevorschläge liegen inzwischen in gut zugänglicher Form vor. Kaum angemessene Berücksichtigung als Unterrichtsthema fand bisher der Neuplatonismus, eine der bedeutendsten und wirksamsten philosophischen Richtungen der Renaissance.

 Prof. Dr. Clemens Zintzen, der Präsident der Mainzer Akademie der Wissenschaften und der Literatur, Prof. em. für Klassische Philologie an der Universität Köln und international renommierter Kenner der Philosophie des Neuplatonismus sowie der Florentiner Renaissance, stellt in seinem kenntnisreichen, höchst anregenden Beitrag mit Marsilio Ficino einen der wichtigsten Vertreter des Neuplatonismus in der italienischen Renaissance des 15. Jahrhunderts vor. Der Beitrag enthält somit nicht nur zahlreiche Anregungen für den Lateinunterricht, sondern kann auch dem Griechischunterricht wertvolle Impulse verleihen.

 Der Artikel führt in Leben und Werk Ficinos ein und skizziert die Grundzüge seiner Philosophie. Ficinos Ontologie fußt auf der Philosophie Plotins, berücksichtigt aber auch die christliche Lehre. Zentrale Punkte seiner Lehre sind die Mittelstellung der menschlichen Seele, ihre Unsterblichkeit, die vita contemplativa als die für die Rückkehr zu Gott angemessene Lebensform und schließlich die "Platonische Liebe" als das rechte Verhältnis des Menschen zu Gott. Ficinos Auffassung von Kunst wird am Ende des Beitrages ebenfalls kurz berührt.

description: В статье анализируется набор видов лекарственных растений в аридных и семиаридных биомах России. Выявлено видовое разнообразие лекарственных растений в целом, а также применяемых для лечения заболеваний различных классов. Проведен статистический анализ связей между числом видов лекарственных растений в региональных биомах и климатическими показателями, построены соответствующие тематические картосхемы и дан их анализ. Показано, что число видов лекарственных растений связано с общим количеством видов в биомах, которое, в свою очередь, обусловлено географическим положением, определяющим среднегодовую температуру и количество осадков в регионах. Наиболее тесная связь установлена между числом видов лекарственных растений и среднегодовыми температурами воздуха. Относительно высокая связь выявлена между числом видов и среднегодовым количеством осадков. При анализе связей числа видов лекарственных растений, применяемых для лечения определенных классов болезней, с климатическими факторами, картина получилась аналогичной.

description: Рассмотрена фитоценотическая характеристика китайсколеймусовых сообществ, произрастающих на разных типах почв луговой степи, остепненной поймы и галофитных лугов Западного Забайкалья. В ботаническом составе выявлено 28 видов гликофитов, 17 галотолерантных гликофитов и 6 галофитов. Установлено, что род Leymus включает 3 вида: Leymuschinensis , L. buriaticus и L. littoralis . Ботанический состав леймусников Западного Забайкалья представлен 51 видами, 20 семействами и 40 родами. Виды относятся к преимущественно степному комплексу с разными вариантами ксерофитов, принадлежащими азиатскому типу ареала. В составе биоморф основная доля приходится на корневищные виды, также значительна доля малолетников. Сходство между видовыми составами леймусников находится в интервале слабое-среднее, что обусловлено значительным участием семейств и родов с малой видовой насыщенностью. Первичная продукция леймусовых сообществ составляет 1029-2370 г/м2·год, надземную фитомассу практически полностью формирует Leymus chinensis . Биохимический состав, кормовая ценность и протеиновое отношение сухого вещества эдификатора определяются условиями произрастания, но в целом они соответствуют нормативным показателям.

Investigation of a variable geometry supersonic diffuser

description: A flexible second throat supersonic diffuser has been tested in the GALCIT 2-1/2 inch supersonic wind tunnel at Mach numbers of 2.60 and 3.33.  The theoretical minimum area relation for starting a supersonic tunnel has been checked at the two Mach numbers, and the amount by which the height of the second throat may be reduced after the tunnel has been started was determined.  Minimum compression ratios for the starting and reduced second throat conditions have been determined and compared with those previously found here and theoretically estimated by Crocco.  Effect of nozzle surface roughness on supersonic flow is noted, and Schlieren photographs representing the flow in a variety of conditions are presented.  A series of Schlieren photographs shows the flow in the second throat at progressively greater amounts of area reduction.

The theoretical minimum second throat area relation was found to predict the second throat size for starting within 3 percent at both Mach numbers, being conservative by that amount in both cases.  Only about 1/3 of the theoretically predicted reduction of second throat area after starting was realized at both Mach numbers before separation of the boundary layer broke down flow throughout the nozzle.  Minimum compression ratios were reduced some 9 and 6 percent for Mach numbers 2.60 and 3.33 respectively.  These decreases, though not as large as anticipated, nevertheless have the lowest compression ratios ever measured in the GALCIT tunnel, ratios less than Crocco's estimate, heretofore never realized.  Transition, though not occurring by means of a normal shock wave, was found to be stable a few inches downstream of the second throat.
