Techniques used in the F-14 variable-sweep transition flight experiment

This paper discusses and evaluates the test measurement techniques used to determine the laminar-to-turbulent boundary layer transition location in the F-14 variable-sweep transition flight experiment (VSTFE). The main objective of the VSTFE was to determine the effects of wing sweep on the laminar-to-turbulent transition location at conditions representative of transport aircraft. Four methods were used to determine the transition location: (1) a hot-film anemometer system; (2) two boundary-layer rakes; (3) surface pitot tubes; and (4) liquid crystals for flow visualization. Of the four methods, the hot-film anemometer system was the most reliable indicator of transition

Bridal Gallery

The Bridal Gallery is in the business of pampering its clients with a full range of bridal products and services, from gowns to garters, shoes to jewels. Located in Huntsville, TX, this small business enjoys a well deserved reputation for offering high quality, competitively priced products. In addition, free one-on-one consultation services are provided to every client. One of the company’s flyers indicates that the Bridal Gallery is “Where expert advice saves you time and money.” Although the company is run by a very knowledgeable owner who is passionate about her business, the financial picture has been very mixed. The owner has not drawn a regular paycheck during the entire eight year history of the business, and the past year resulted in a record net loss. An expanded bridal product line plus diversifying into a prom dress line might generate additional revenue, but due to space constraints, a potentially cost prohibitive move into a larger building might be necessary.(Contact author for a copy of the complete report.)Small Business Mgmt

F-14 VSTFE and results of the cleanup flight test program

Flight transition data applicable to swept wings at high subsonic speeds are needed to make valid assessments of the potential for natural laminar flow or laminar flow control for transports of various sizes at various cruise speeds. NASA initiated the variable sweep transition flight experiment (VSTFE) to help establish a boundary layer transition data base for use in laminar flow wing design. The carrier vehicle for this experiment is an F-14, which has variable sweep capability. The variable sweep outer panels of the F-14 were modified with natural laminar flow gloves to provide not only smooth surfaces but also airfoils that can produce a wide range of pressure distributions for which transition location can be determined. The VSTFE program is briefly described and some preliminary glove I flight results are presented

A Path Towards Intersectionality-Informed Counseling Sexology: A Special Commentary

It is the goal of professionals within the field of counseling sexology and sexual wellness to provide clients with clinical mental health counseling through a sex-positive and affirming framework. To do so, clinicians must pay special attention to best practices in the field, especially as it relates to historically oppressed and minoritized clients. To do so, appropriate training is required to inform care. Furthermore, clinical practice is also informed by research, making it imperative that research is conducted related to various aspects of sexual wellness and treatment. This commentary will identify and discuss sexual health and wellness priorities within the field of clinical mental health counseling to outline future directions for the field

What Are We Missing?: A Comparison of Experiences of Race-Based Trauma by Black Americans and Black Jamaicans

Current literature explains that events resulting from instances of white supremacy and racism are traumatizing for Black individuals (Phillips, 2020). Prior literature illuminates the impact of racism and resulting race-based trauma on Black individuals but is lacking regarding the lived experiences of race-based trauma in Black individuals in the U.S. and Black individuals from Jamaica. The goal of this study was to fill a gap in current literature by providing counselors and counselor educators with information regarding the experiences of Black clients to better inform multicultural, trauma-informed counseling practices and counselor education pedagogy. This study explored the experiences of race-based trauma in Black individuals in the U.S. and Jamaicans identifying as non-white using phenomenological methodology through the lens of Critical Race Theory (CRT). Using a phenomenological methodology grounded in Critical Race Theory, semi-structured interviews were completed with 5 individuals identifying as Black Americans and 5 self-identified Black Jamaicans. Questions used in the interviews were aimed to explore (a) ways in which Black individuals have experienced race-based trauma as previously defined; (b) the impact of majority versus minoritized ethnic group status on the experience of race-based trauma; (c) resiliency factors employed by Black individuals to cope with race-based trauma; and (d) if and how race-based trauma impacts the daily functioning and behaviors of individuals self-identifying as Black. The findings of this study illuminate the experiences of these individuals as it relates to race-based trauma and the resiliency factors employed to facilitate coping. Furthermore, a cross-cultural examination of the experiences of racism when the individual is in the majority racial group in their nation, compared to when they are not within the majority racial group is presented, thereby providing the counseling profession with a broader illustration of the Black experience. Implications for licensed professional counselors, supervisors, and counselor educators are presented

Understanding Incarcerated Education: A Review of the Digital and Gender Inequality Impacts of Accessibility and Inclusivity of Higher Education for Incarcerated Students

Education in the correctional environment is endorsed as an effective rehabilitative tool linked to reducing recidivism and improving reintegration. Unfortunately, while researchers from the Global North are particularly active on the subject of the accessibility of digital education in corrections, the same cannot be said for the Global South. Of further concern is that few of the studies conducted have focused specifically on incarcerated women’s access to education. As discussed in the literature review to follow, research regarding higher education in corrections has the potential for expanding academics, stakeholders, and policy makers understanding of incarcerated students’ pathways towards education attainment. Using an intersectional feminist framework, I argue that there is a need for further research on Global South and gender responsive perspectives on carceral education. Research on the topic can identify opportunities offered and challenges faced, as well as the possible implications for students broader societal functioning post-release

Simplicity in simplicial phase space

A key point in the spin foam approach to quantum gravity is the implementation of simplicity constraints in the partition functions of the models. Here, we discuss the imposition of these constraints in a phase space setting corresponding to simplicial geometries. On the one hand, this could serve as a starting point for a derivation of spin foam models by canonical quantisation. On the other, it elucidates the interpretation of the boundary Hilbert space that arises in spin foam models. More precisely, we discuss different versions of the simplicity constraints, namely gauge-variant and gauge-invariant versions. In the gauge-variant version, the primary and secondary simplicity constraints take a similar form to the reality conditions known already in the context of (complex) Ashtekar variables. Subsequently, we describe the effect of these primary and secondary simplicity constraints on gauge-invariant variables. This allows us to illustrate their equivalence to the so-called diagonal, cross and edge simplicity constraints, which are the gauge-invariant versions of the simplicity constraints. In particular, we clarify how the so-called gluing conditions arise from the secondary simplicity constraints. Finally, we discuss the significance of degenerate configurations, and the ramifications of our work in a broader setting.Comment: Typos and references correcte

Improved and Perfect Actions in Discrete Gravity

We consider the notion of improved and perfect actions within Regge calculus. These actions are constructed in such a way that they - although being defined on a triangulation - reproduce the continuum dynamics exactly, and therefore capture the gauge symmetries of General Relativity. We construct the perfect action in three dimensions with cosmological constant, and in four dimensions for one simplex. We conclude with a discussion about Regge Calculus with curved simplices, which arises naturally in this context.Comment: 28 pages, 2 figure

Engineering Electron Superpositions Using a Magnetic Field

A Rydberg atom has a highly excited valence electron which is weakly bound and far from the nucleus. These atoms have exaggerated properties that make them attractive candidates for quantum computation and studies of fundamental quantum mechanics. The discrete energy levels of Rydberg atoms are shifted in the presence of an electric field by the Stark effect and are similarly shifted due to a magnetic field by the Zeeman effect. These effects couple the energy levels together, creating avoiding crossings. At these avoided crossings, an electron in one energy level can jump to the other. Our goal is to be able to use these avoided crossings to put the electron in a superposition state of both energy levels. In order to achieve this we created new software that enables us to calculate the energy levels of an electron in both a magnetic and an electric field. We present energy level maps visualizing the results of the Stark and Zeeman effects
