A Technique of Improved Medial Meniscus Visualization by Anterior Cruciate Ligament Graft Placement in Chronic Anterior Cruciate Deficient Knees

It is customary to perform medial meniscus repair before anterior cruciate ligament (ACL) graft placement when undertaken as a combined procedure. However, in chronic ACL-deficient knees, intraoperative anterior tibiofemoral translation can cause the medial meniscus repair to be more technically challenging. Intraoperative anterior tibiofemoral translation can both reduce the visualization of the medial meniscus and make its reduction unstable. An operative sequence alteration of ACL graft placement and tensioning before medial meniscal repair improves medial meniscus visualization in chronically ACL-deficient knees by using the ACL graft’s ability to prevent anterior tibiofemoral translation. The technique sequence is as follows: (a) the medial meniscus is reduced, (b) ACL reconstruction is undertaken using a hamstring graft without final tibia fixation, (c) distal graft tension is manually applied to distal graft sutures by the surgeon to prevent tibiofemoral subluxation, (d) the medial meniscus is repaired while graft tension is applied, and (e) the graft is then fixed to the tibia using an interference screw or another device

Does the threat of disqualification deter drivers from speeding?

Road Safety Research Report, number 96, is available from the National Archives: Department for Transport, and can be accessed from the link below.It has long been recognised that driving speeds that are excessive and inappropriate to the conditions are a major contributory factor in road accidents, and a major issue for road safety. Restraining driving speeds has proved to be a difficult task, given the improvements over the years in both vehicle performance and road design. Within the traditional ‘three Es’ countermeasures of engineering, education and enforcement, recent years have seen the introduction of a wide range of engineering measures designed to bring about speed reduction, but these tend to be restricted to specific parts of the road network. New technologies such as Intelligent Speed Adaptation (ISA) offer considerable promise, but mainly in the medium or longer term. Similarly, educative efforts to induce attitude and behaviour change in this context are bearing fruit, yet this is a long-term rather than short-term project. For the foreseeable future, enforcement will remain the principal means of influencing speed, by setting speed limits and imposing sanctions on drivers who are caught exceeding them. The number of licence endorsements has increased enormously in recent years. However, over the same period the number of disqualifications resulting from ‘totting-up’ points has decreased. This would seem to indicate that many drivers who accumulate up to 11 penalty points are either acting as if deterred by the threat of disqualification, or are avoiding disqualification in some other way. The extent to which penalty points act as a deterrent for the benefit of road safety in general is therefore an important issue, and this report describes work that has been carried out to study this issue by TRL and Brunel University, under contract to the Department for Transport

Working with a Different Drummer: Transgender or Gender Creative Children and Their Families

Anomalous magnetoresistance peak in (110) GaAs two-dimensional holes: Evidence for Landau-level spin-index anticrossings

We measure an anomalous magnetoresistance peak within the lowest Landau level (nu = 1) minimum of a two-dimensional hole system on (110) GaAs. Self-consistent calculations of the valence band mixing show that the two lowest spin-index Landau levels anticross in a perpendicular magnetic field B consistent with where the experimental peak is measured, Bp. The temperature dependence of the anomalous peak height is interpreted as an activated behavior across this anticrossing gap. Calculations of the spin polarization in the lowest Landau levels predict a rapid switch from about -3/2 to +3/2 spin at the anticrossing. The peak position Bp is shown to be affected by the confinement electrostatics, and the utility of a tunable anticrossing position for spintronics applications is discussed.Comment: 4 pages, 4 figure

Control of Oxygen and Carbon Related Crystal Defects in Silicon Processing

In the production of silicon articles at an elevated temperature, a stream comprising a controlled mixture of an oxygen-containing first gas and a second gas is admitted to the processing chamber. The first gas is one which partially dissociates under the conditions in the chamber to form both oxygen and the second gas. The second gas is one which is not harmful to silicon at the conditions in the chamber. Substantially equilibrium conditions are established in the chamber so that the dissociation of the first gas to oxygen occurs reversibly. The partial pressure of oxygen (PO2) is sensed in the chamber during processing of the article. In response to the PO2 level, the ratio of the rates of flow of the oxygen-containing gas and the second gas is adjusted so as to maintain the PO2 at a level less than about 10-6 atmosphere, and usually no greater than about 10-10 atmosphere, at which the density of oxygen-related defects in the processed silicon article is acceptably low. Oxygen-related defects in the silicon are thereby reduced. If graphite structures are present in the hot zone of the processing chamber, they are preferably coated with an impervious coating which will stand the high temperature and will prevent the gas stream from coming into contact with the hot graphite. Carbon-related defects in the silicon are thereby also reduced

28666 Global initiatives in dermatology and education

Background: Coronavirus disease 2019 (COVID-19) resulted in a global pandemic that has adversely affected the economy, healthcare, and education around the world. The resulting travel restrictions, physical distancing policies, and limited social interactions have led to an inevitable change in the medical education system. The use of technology platforms to teach, connect, and collaborate is crucial to maintain education standards and research projects. We present an international exchange program with a videoconferencing series that allows residency programs to sustain international educational partnerships during COVID-19 and thereafter. Description: A series of 60-minute videoconferencing lectures were held for residents at both Henry Ford Hospital (HFH) in Detroit, Michigan and Universidad El Bosque in Bogotá, Colombia to participate in simultaneously. Sessions were hosted by faculty members from HFH on subjects including but not limited to: oncodermatology, comparative dermoscopy, and cutaneous T-cell lymphoma. Learning objectives were developed for each videoconference and participants answered a series of questions to assess (a) their knowledge and (b) lecture content. Results of the surveys serve as the core of our evaluation. Goals: Teach residents about new approaches to diagnosis and treatment, improve social and intercultural competencies, and increase interest in global health and caring for the underserved. Conclusion: The videoconferencing series component of this mutually beneficial international exchange partnership is of utmost importance given the circumstances of COVID-19. In addition to continuing education and collaboration, videoconferencing allows the interactive format of in-person lectures to be maintained while adhering to distancing guidelines
