Positive sequence pilot impedance protection of AC tie line based on MMC-HVDC system

MMC-HVDC has the characteristics of limited amplitude, controlled phase angle and unequal positive and negative sequence impedance. Therefore, the fault characteristics of flexible direct system and AC power grid tie line are quite different from traditional synchronous power supply, which may affect the performance of AC power grid sudden variable protection. Therefore, a new AC protection method based on positive sequence current sudden variable impedance is proposed. The results show that when an in zone fault occurs, the direction of current sudden changes at both ends is the same, and the positive sequence impedance may approach the line impedance; When an out of area fault occurs, the current abrupt variables at both ends have opposite directions and equal sizes, and the positive sequence impedance is much greater than the line impedance. Based on the above characteristics, the criteria of fault start up and fault type are constructed. The simulation results show that the protection method can realize fault discrimination quickly and reliably.

Reviewing suitability of Essex Partnership University Foundation NHS Trust out of area locked rehab placements

AimsTo look at 14 EPUT out of area patient profiles, map their journey to the current locked rehab placements -To review the appropriateness of placement of 14 patients through reviewing whether the care provided is achieving the rehabilitation goals.To look at patients’ needs and whether the local alternatives can provide the careBackgroundRehabilitation services aim to help complex General Adult Mental health patients reintegrate in the community by promoting independent living skills. Some complex mental health patient's care needs mandate a specialist rehabilitation services. Currently there has been a nationwide shortage of local rehabilitation services. This resulted in placing complex needs patients out of area in locked rehabilitation hospitals and miles away from their local community connections. Families and local community team providers travel miles to keep in contact with their complex need persons. The NHS five year plan includes minimizing the current out of area placements and for local services to work together as per CQC recommendations to work together and bring those individuals closer to home.MethodWe designed a tool and examined the electronic records for all 14 out of area placed patient profiles, mapping their clinical journey and reviewing whether the care provided is achieving the rehabilitation goals.Result(N = 14), Patient profiles: 78.5% had residual symptoms (Psychotic symptoms 85%). Patient's Illness profile; treatment resistant with residual symptoms in 71.4% and 7% had comorbid illicit substance misuse, other illness profiles 21.4%. History of alcohol and illicit drug misuse was present in 78.5% and 45% of them were using illicit substances more than 5 years. .patients’ risk profile revealed 86.7% had history of non-compliance. Attempted suicide 21.4% has attempted suicide at list once in which 1/3 of them had more than one attempt. 64.3% Had positive history of offending behavior. All patients in the sample had history of violence 85.7% had risk of vulnerability and self-neglect, 28.5% has history of carrying weapons, 35.7 had a previous Custodial sentence. Average Duration of illness average 16.7 years, average distance from home was 149 miles though clozapine was considered in 92.8% only 35.7% of sample was on clozapine, and the other 64.3% were on combinations. Only 35.7% were on depot.ConclusionThere is a need for expert input for advice regarding complex Management of residual symptoms and rehabilitation needs in the community. Health and social care joint working is needed.

Who commits the most to NATO? It depends on how we measure commitment

Studies of NATO rely heavily on military spending as a fraction of GDP as the key indicator of members’ contribution to the alliance, but a growing number of scholars have challenged this approach. We suggest that each member’s public goods provision is a better measure of commitment to the alliance. In the case of post-Cold War NATO, out-of-area troop deployments (adjusted for population) constitute one of the strongest indicators of a state’s contribution to public goods. Providing troops for NATO missions in Afghanistan, Kosovo, and Bosnia-Herzegovina is one of the clearest signals of high commitment to the alliance. Using deployment data from 2004 to 2018, we show that there is evidence of disproportionate burden-sharing within the alliance. Countries like Slovenia, Denmark, the USA and UK contributed far more to NATO deployments than others like Turkey, Spain, Poland, and Portugal. We also use the data to begin examining possible causes of these disparities. We find that wealthier countries, countries that spend more on their militaries, and newer alliance members are more likely to contribute. Our indicator and first-cut model open avenues for further research on why some members demonstrate higher commitment to NATO than others.

Victory and the West

This chapter examines the state of transatlantic relations at the end of the Cold War. It takes particular issue with the notion that the Cold War had been a golden age of transatlantic cooperation. The Cold War had witnessed the emergence of a transatlantic community. But that community had been in a perpetual state of inner conflict and disagreement. NATO had almost fallen apart in the 1960s when France exited the alliance’s unified military command. Conflicts over burden-sharing and out-of-area engagements, over national subsidies and trade rules had been frequent. Before the Berlin Wall came down, the alliance had already survived, even thrived, through many internal crises. Paradoxically, when the Cold War in Europe ended, the “West” was at the same time more diverse and more united than at any time in the past.

817 A Case of Parasomnia Overlap Disorder in a Patient on Lithium

Introduction The literature contains few case reports of parasomnia overlap disorder. There are also few case reports of lithium inducing sleep walking behaviors. Here we seek to present a case of a patient with multiple parasomnias, is taking a number of psychotropic medications for bipolar I disorder, and is on PAP for OSA. Report of case(s) The patient is a 43 year old male with a history of occasional mild sleep walking since childhood that remitted approximately 10 years prior to the onset of treatment, but returned when he traveled out of area for a family gathering approximately one year prior to presentation in the sleep clinic. He reported not only the return of sleepwalking, on a nightly basis, as well as more severe symptoms (including enuresis and violence/aggression). He also reported several episodes of dream enactment, as well as a history of sleep paralysis and vivid hypnogogic hallucinations, both of which had been improved in the last year. He denied any history of cataplexy. He did complain of symptoms of significant RLS symptoms. He was partially compliant with CPAP for obstructive sleep apnea, though the sleep behaviors continued regardless of CPAP usage. His psychiatrist had started him on clonazepam (titrated to 2mg/night) prior to his intake in the sleep clinic, but with minimal benefit. His other medications included propranolol 40mg BID, lithium 900mg/1200mg, oxcarbazepine 600mg bid, lamictal 225mg bid, lurasidone 80mg qday, and benztropine 2mg bid. Attended polysomnography demonstrated five episodes of sleep behaviors, as well as loss of atonia during REM, and severe obstructive sleep apnea (AHI of 61.2). Conclusion The patients various parasomnias could be due to the side effects of his psychotropic medications, represent a genetic or structural defect that is causing the various parasomnias, or be due to or worsened by his undertreated obstructive sleep apneas. His workup and treatment is still ongoing, but he has continued on clonazepam 2mg but taken 2 hours earlier, and has started a new APAP. Because of the severity of his bipolar disorder (including severe suicidal ideation), he is not a candidate to tapering the lithium or to taking serotonergic antidepressants. Support (if any):

When peace nations go to war: Examining the narrative transformation of Sweden and Norway in Afghanistan

What happens to dominant narratives and settled self-images of so-called peace nations when experiencing actual combat in out-of-area military missions? This question arises when studying the contemporary international engagement of small states that previously have mostly been engaged in peacekeeping with limited mandates and non-use of force restrictions. As today's international missions have altered radically, it is important to analyse narrative friction and transformation in small states with little prior experience of international war-fighting. This article addresses this lacuna by examining two small states and self-proclaimed peace nations – Sweden and Norway – in relation to their engagement in the International Security Assistance Force (ISAF), the NATO-led security mission to Afghanistan 2002–14. By examining the interplay and discursive struggle of two narratives — peace nation and military culture – this article finds that these narratives constantly constitute and reconstitute a small state's self-image and the boundaries for acceptable or even required behaviour. With altered principles regarding use of force there is an increased friction between the narratives. By addressing these frictions, the article contributes to the literature on small state international military engagement and develops and refines assumptions regarding the drivers and consequences of small state participation in out-of-area missions.

Out of area housing by local authorities in England: displacement of vulnerable households in a neoliberal housing crisis

Based on freedom of information responses from English local authorities, the research examines the number of households where a duty to accommodate was accepted that were subsequently housed in other local authority areas. Recognising neoliberal housing policy of increased marketisation and less government intervention, the article identifies market failure, housing unaffordability and welfare reform contributing to households being displaced and social cleansing. Importantly, the research recognises negative housing outcomes beyond the binary of homelessness and the impact on vulnerable households by examining out of area housing, which is currently an under-researched area within housing.

Informal Volunteering Helps Older Adults Stay Put Too! But, Does Gender Matter?

Many older adults desire to remain in one’s home for as long as possible, and many factors have been identified to be helpful, such as formal volunteering (doing unpaid work for religious, educational, health-related or other charitable organizations). While many older adults volunteer formally, many others volunteer informally (providing unpaid help to friends, neighbors, or relatives who did not co-reside). However, less is known about the relationship between informal volunteering and relocation. Guided by the social and material convoy framework, the present study explores the intersection of gender, informal volunteering, and relocation (no move, move within area, and move out of area). Utilizing data from 2008 and 2010 Health and Retirement Study, 8,361 older adults who were 65 and above in 2008 were included. When older people’s financial resources, health, environment, and demographics were controlled, findings from multinomial logistic regression showed that older adults who volunteered informally were less likely to move within area two years later. When stratified by gender, it was found that female (n=4,832) volunteered informally in 2008 were less likely to move within area within two years, too; whereas for male (n=3,529), those who informal volunteered in 2008 were less likely to move out of area in 2010. According to the findings, informal volunteering helps older adults stay put. Future research is needed to understand why informal volunteering helps reduce short distance moves for women but helps reduce long distance moves for men.
