Early focus development effort, ultrasonic inspection of fixed housing metal-to-adhesive bondline

An ultrasonic technique was developed for the fixed housing metal-to-adhesive bondline that will support the Flight 15 time frame and subsequent motors. The technique has the capability to detect a 1.0 inch diameter unbond with a 90 percent probability of detection (POD) at a 95 percent confidence level. The technique and support equipment will perform within the working envelope dictated by a stacked motor configuration

Flipped: The Lives of Those with Mental Disorders

This collection of four short stories focus on how society perceives those with mental disorders, the stigma associated with those disorders, and how both of these affect the people who have mental disorders. The stories are designed to give a general audience insight into the lives of those with various mental disorders. In everyday settings, these stories revolve around ordinary actions of the characters, with and without mental disorders. Each story will contain two parts, the first part is a record of the incident from the perspective of a person without a mental health diagnosis and who is unrelated to the person with the diagnosis. The second part is a retelling of the same scene from the perspective of the character with the mental health disorder. These stories revolve around the four main characters with mental disorders. The process started with the creation of the main characters, ensuring the characters are characters who have a mental disorder, not characters designed around a mental disorder. After the main characters were developed, the events, setting, and secondary character for each scene were designed to best showcase the difficulties those with mental disorders face and highlight the differences in mental functioning. Concepts and materials from the abnormal psychology, along with the DSM-V was the starting point for the symptoms and presentations of various disorders. Multiple case studies and some anecdotal stories from those with the disorders portrayed was used to craft the stories and ensure realism. Many people do not understand what those with mental illness go through, and more importantly, they don’t understand that they are really just people in the end. The main goals of these stories is to give the general public insight into this, in an easy and relatable manner

The annual cycle of Northern Hemisphere storm-tracks. Part 2: regional detail

In Part 1 of this study, the annual cycle of the Northern Hemisphere storm-tracks was investigated using feature tracking and Eulerian variance based diagnostics applied on both vorticity and meridional wind. Results were presented and discussed for the four seasons at both upper (250hPa) and lower (850hPa) tropospheric levels. Here, using the meridional wind diagnostics, the annual cycles of the North Pacific and North Atlantic storm-tracks are examined in detail. This is done using monthly and 20° longitudinal sector averages. Many sectors have been considered, but the focus is on sectors equally spaced in the two main oceanic storm-tracks situated at their western, central and eastern regions, the western ones being mainly over the upstream continents. The annual cycles of the upper and lower tropospheric storm-tracks in the central and eastern Pacific, and western and central Atlantic sectors all have rather similar structures. In amplitude, each sector at both levels has a summer minimum and a relatively uniform strength from October to April, despite the strong winter maxima in the westerly jets. However, high intensity storms occur over a much wider latitudinal band in winter. The storm-track in each sector moves poleward from May to August and returns equatorward from October to December, and there is a marked asymmetry between spring and autumn. There are many differences between the North Pacific and North Atlantic storm-tracks, and some of these seem to have their origin in the behaviour over the upstream East Asian and North American continents, suggesting the importance of seeding from these regions. The East Asian storm-track near 48°N has marked spring and autumn maxima and weak amplitude in winter and summer. The 33°N track is strong only in the first half of the year. In contrast, the eastern North American storm-track is well-organised all year, around the baroclinicity that moves latitudinally with the seasons. The signatures associated with these features are found to gradually decrease downstream in each case. In particular, there is very little latitudinal movement in the storm-track in the Eastern Atlantic

The annual cycle of Northern Hemisphere storm-tracks. Part 1: seasons

In this paper and Part 2 a comprehensive picture of the annual cycle of the Northern Hemisphere storm-tracks is presented and discussed for the first time. It is based on both feature tracking and Eulerian based diagnostics, applied to vorticity and meridional wind in the upper and lower troposphere. Here, the storm-tracks, as diagnosed using both variables and both diagnostic techniques, are presented for the four seasons for each of the two levels. The oceanic storm-tracks retain much of their winter mean intensity in spring with only a small change in their latitude. In the summer they are much weaker, particularly in the Pacific and are generally further poleward. In autumn the intensities are larger again, comparable with those in spring, but the latitude is still nearer to that of summer. However, in the lower troposphere in the eastern ocean basins the tracking metrics show northern and southern tracks that change little with latitude through the year. The Pacific mid-winter minimum is seen in upper troposphere standard deviation diagnostics, but a richer picture is obtained using tracking. In winter there are high intensities over a wide range of latitudes in the central and eastern Pacific, and the west Pacific has high track density but weak intensity. In the lower troposphere all the diagnostics show that the strength of the Pacific and Atlantic storm-tracks are generally quite uniform over the autumn-winter-spring period. There is a close relationship between the upper tropospheric storm-track, particularly that based on vorticity, and tropopause level winds and temperature gradients. In the lower troposphere, in winter the oceanic storm-tracks are in the region of the strong meridional SST gradients, but in summer they are located in regions of small or even reversed SST gradients. However, over North America the lower tropospheric baroclinicity and the upstream portion of the Atlantic storm-track stay together throughout the year

A frontline service? Nursery Schools as local community hubs in an era of austerity

Nursery Schools in the UK have been described as the ‘jewel in the crown’ of early years provision because of the quality of education and a wide range of other support services that they provide, particularly for children from socio-economically disadvantaged families and those with complex special educational needs (SEN). In this paper, we explore the role of Nursery Schools in the local community, arguing that they have been re/constructed as a frontline service in the context of austerity policies enacted in England over the past decade. The data presented in support of this argument arise from detailed interviews with 17 staff based in four Nursery Schools. Our data lead us to argue that, in the current context of austerity and cuts to a range of local services, Nursery Schools are filling welfare gaps for families by providing clothing, trips and food voucher advice to families. They are also supporting increasing numbers of SEN children and are described as a first point of contact with state-run services by many, especially minority ethnic and working-class families. We conclude by arguing that Nursery Schools’ funding must be protected so that they can continue to provide support to some of the most vulnerable children and their families in England

On the importance of testing gravity at distances less than 1cm

If the mechanism responsible for the smallness of the vacuum energy is consistent with local quantum field theory, general arguments suggest the existence of at least one unobserved scalar particle with Compton wavelength bounded from below by one tenth of a millimeter. We show that this bound is saturated if vacuum energy is a substantial component of the energy density of the universe. Therefore, the success of cosmological models with a significant vacuum energy component suggests the existence of new macroscopic forces with range in the sub-millimeter region. There are virtually no experimental constraints on the existence of quanta with this range of interaction.Comment: 9 pages TeX, 2 eps figures, uses mtexsis.tex and epsf.tex.

Theorising Academic Career 'Success'

ASIN: ‎B08DC6GY6BCopyright © The Author 2020. The purpose of this short piece is to examine literature exploring the concept of ‘success’. Drawing on my research examining how female professors construct their career success, the aim is to highlight the contested nature of what constitutes ‘success’, and to consider how this knowledge could be drawn on by policy-makers to better inform attempts to improve academic outcomes for all children, regardless of their background
