The pressure control for a liquid nature gas ship is vital for the cargo handling system which is a nonlinear, unstable, and controllable complex system accompanied by the dynamics of time delay. To improve the control effect, this article proposed a robust controller based on closed-loop gain shaping algorithm by mirror-mapping approach. In addition, the complete mechanism models for the system are established to predict the changes of temperature, pressure, and liquid inventory in the cargo tank. The heat exchanges and (...) evaporation of liquid are also considered. By collecting the data from the LNG ship “Dapeng,” the system models are validated. At the same time, the comparative experiment is introduced to verify the reliability and effectiveness. The scheme has been compared with the 2-DOF structure control law of modified Smith predictor. The comparative experimental results show that the scheme proposed in this note has a strong disturbance rejection ability and steady-state performance. The controller designed in this note has advantages of simplified construction method, satisfactory control effect and robustness. (shrink)

If one takes Heidegger at his word then his philosophy is about pursuing different "paths" of thought rather than defining a single set of truths. This volume gathers the work of an international group of scholars to present a range of ways in which Heidegger can be read and a diversity of styles in which his thought can be continued. Despite their many approaches to Heidegger, their hermeneutic orientation brings these scholars together. The essays span themes from the ontic to (...) the ontological, from the specific to the speculative. While the volume does not aim to present a comprehensive interpretation of Heidegger's later thought, it covers much of the terrain of his later thinking and presents new directions for how Heidegger should and should not be read today. Scholars of Heidegger's later thought will find rich and original readings that expand considerations of Heidegger's entire oeuvre. (shrink)

ObjectiveTo investigate post-traumatic stress disorder, perceived professional benefits and post-traumatic growth status among Chinese nurses in the context of the COVID-19 pandemic and to compare the differences between nurses working inside and outside Hubei.MethodsFrom February 18 to February 25, 2020, the authors constructed the questionnaire using the Questionnaire Star platform, and convenience sampling was used to distribute the questionnaire via WeChat. Nurses who worked at the hospital during the COVID-19 pandemic were the research subjects.ResultsA total of 3,419 questionnaires were received, (...) of which 2,860 nurses were working outside Hubei Province and 559 nurses were working inside Hubei Province. Both groups were exposed to COVID-19. The results indicated that gender, job title, department, average monthly income, the number of night shifts per month, hospital classification, specialization, and previous experience with assisting during disasters were statistically significant. The t-test results showed that the difference in perceived professional benefits scores between the two groups was not statistically significant, and the differences in PTG scores and PTSD scores between the two groups were statistically significant. The chi-square test indicated that the difference in PTSD prevalence between nurses working outside and inside Hubei Province was statistically significant and that the PTSD prevalence of nurses working outside Hubei Province was higher than that of nurses working inside Hubei Province. One-way ANOVA and independent sample t-test results showed that age, job title, job assignment, length of service, average monthly income, number of night shifts per month, number of children, and the Nurses’ Perceived Professional Benefits Scale and post-traumatic growth inventory scores influenced the prevalence of PTSD. Logistic regression showed that the occurrence of PTSD was associated with average monthly income, length of service, number of children, and the PTGI and NPPBS scores.ConclusionDuring the COVID-19 pandemic, nurses working outside Hubei Province reported greater PTSD than those working inside Hubei Province. The occurrence of PTSD was related to average monthly income, length of service, number of children, and the PTGI and NPPBS scores. (shrink)

_ Source: _Volume 48, Issue 2, pp 233 - 243 This article focuses on two Platonic concepts, δύναµις and χώρα, and Heidegger’s interpretation of them in his lecture courses on Greek philosophy. I try to demonstrate that these two concepts offer us insights into the dynamic movement of Being between self-showing and withdrawal. The aim of the article is to show that Being, as one of the greatest kinds in the _Sophist_, and the elusive χώρα in the _Timaeus_ can open (...) up new perspectives on the Heideggerian question of Being.

Objective: We aimed to evaluate the activity of the human glymphatic system in type 2 diabetes mellitus using diffusion tensor image analysis along with the perivascular space.Methods: Diffusion tensor images were acquired to calculate the diffusivities in the direction of the x-axis, y-axis, and z-axis of the plane of the lateral ventricle body in 20 patients with type 2 diabetes and 10 people in a control group. We evaluated the diffusivity along with the perivascular spaces, as well as the projection (...) fibers and association fibers, separately. The analysis along the perivascular space was defined as the mean /mean, where the Dxpro and Dxasc were the Dx values in the projection and association fiber areas, respectively.Results: There were significant differences in diffusivity along the projection fibers and the association fibers among the groups. The significant differences among the groups along the perivascular spaces, shown as the ALPS-index and medical history of T2DM, indicating lower water diffusivity along the perivascular space concerning type 2 diabetes severity, was also observed.Conclusion: Lower diffusivity along the perivascular space on DTI-APLS can reflect impairment of the glymphatic system in T2DM. This study showed that the activity of the glymphatic system could be evaluated by diffusion tensor image analysis. (shrink)

Guang Yangs Arbeit nimmt die zentrale Frage des heideggerschen Denkens nach dem Wesen des Logos und der Sprache wieder auf, verbindet sie aber mit dem Begriff der Dynamis. So erweist sich der Logos als diejenige Kraft, die zwischen Bewegung und Ruhe vermitteln und damit die Bewegtheit des Seins in sich versammeln kann. Mit dieser in sich gesammelten Kraft hängt auch das Phänomen der Ruhe zusammen, welches die Bewegung auffängt und entsprechend aufgewertet werden muss. Dieser in der Heidegger-Forschung selten beachtete Gedanke (...) der Ruhe deutet auf die privative Dimension des Seins hin, die auch bei Phänomenen wie räumlicher Leere und der Stille zum Tragen kommt und dabei nicht negativ zu fassen ist. In dieser Untersuchung wird zudem - mit und gegen Heidegger - der Möglichkeitscharakter des Seins hervorgehoben, der nicht allein in der vollzugshaften Bewegung aufgeht. (shrink)
