We have designed and built an electronic device which compares the resistance of a defined area of vacuum evaporated material with a variable resistor. When the two resistances are matched, the device automatically disconnects the primary side of the substrate transformer and stops further evaporation.This approach to controlled evaporation in conjunction with the modified guns and evaporation source permits reliably reproducible multiple Pt shadow films from a single Pt wrapped carbon point source. The reproducibility from consecutive C point sources is also reliable. Furthermore, the device we have developed permits us to select a predetermined resistance so that low contrast high-resolution shadows, heavy high contrast shadows, or any grade in between can be selected at will. The reproducibility and quality of results are demonstrated in Figures 1-4 which represent evaporations at various settings of the variable resistor.

Weaning Criteria

Introduction : The Neurocritical Care Society encourages an external ventricular drain (EVD) wean “as quickly as is clinically feasible” but guidelines on achieving it are limited (1). This study aims to improve quality of care by sharing a protocol to initiate EVD weaning. These criteria were developed over 7 years and showed a reduction in ventriculoperitoneal shunt/endoscopic third ventriculostomy (VPS/ETV) placement and length of stay (LOS) at our institute compared to national averages. Methods : 151 subarachnoid hemorrhage (SAH) patients from January 2016 to January 2019 were analyzed. 60 aneurysmal SAH (aSAH) and 18 non‐aneurysmal nontraumatic SAH (naSAH) patients required EVD placement. A gradual EVD weaning protocol was initiated if patients met the following criteria: the reason for EVD placement has resolved or is resolving, quantity of CSF output must be <250mL over 24 hours, quality of CSF must be nonbloody, ICP must be within normal limits, and the patient must be neurologically stable. It was acceptable to wean when the patient had mild cerebral vasospasm, but not moderate to severe cerebral vasospasm. EVD weaning was performed by increasing drain height by 5 millimeters of mercury every 24 hours if criteria were met. Charts were reviewed for LOS and rate of VPS/ETV. Gender, age, race, wean failure incidence, infection rates, and SIADH/CSW rates were obtained. Results : Average LOS for aSAH patients with EVD at our institute was 20.35 days. Incidence of VPS/ETV was 11%. Chi‐square analysis was performed, and aSAH patients were found to have higher rates of VPS/ETV placement (p<0.001) and EVD wean failures (p<0.001) than naSAH patients. Conclusions : Our criteria to initiate EVD weaning provided a reduction in VPS/ETV placement among aSAH patients compared to national averages and provides a standardized approach to EVD management. aSAH patients at our institute had a lower incidence of VPS/ETV placement of 11% compared to 21% nationally (2). aSAH patients at our institute also had a lower LOS at 20.35 days compared to 21.5 days nationally (3).

Simulation tests have currently become very popular. It gives access to values and parameters which are difficult or impossible to obtain in real conditions. However, in many cases the accuracy of the results may raise concerns, as not every researcher conducts verification tests. This article looks into the quality of results obtained in virtual tests. The tests were conducted using a pin-on-disc station. The main parameter of the verification study was the temperature of the pin measured along its axis at 1mm from the friction surface. This shows that computer models produce results which accurately reflect real-life phenomena.

In the past 16 years, research on mitophagy has increasingly expanded to a wider range of subjects. Therefore, comprehensively analyzing the relevant progress and development trends on mitophagy research requires specific methods. To assess the hotspots, directions, and quality of results in this field worldwide, we used multiple tools to examine research progress and growing trends in research on the matter during the last 16 years (from 2005 to 2020). We also compared the quantity and quality of the literature records on mitophagy published by research institutions in China and other developed countries, reviewed China’s contribution, and examined the gap between China and these developed countries. According to the results of our bibliometric analysis, the United States and its research institutes published the most papers. We identified cell biology as the most commonly researched subject on mitophagy and AUTOPHAGY as the most popular journal for research on mitophagy. We also listed the most cited documents from around the world and China. With gradually increased funding, China is progressively becoming prominent in the field of mitophagy; nevertheless, the gap between her and major countries in the world must be closed.

The article presents the conclusion of the practical experience as well as the results of the author's research in the field of airport management, formulated in the context of the implementation of the investment of the Central Polish Airport. The subject of the considerations and implications is the process of designing the Airport Master Plan – AMP, which in the current situation should be modified in order to ensure effectiveness and efficiency of implementation and quality of results. At the beginning, AMP was characterized on the basis of a study concerning legal acts and selected standard documents, and a study of the quality and risk issues of the AMP was carried out. On the basis of the results obtained, conclusions have been formulated regarding the need for standardization and integration of the dynamic process of AMP design.

Abstract This paper discusses the properties of possible virtual prototyping systems using finite element analysis and reports on a prototype implementation of such a system in order to illustrate the concepts. Virtual reality user interfaces will improve some existing applications and lead to new application domains. Several crucial points such as overall system architecture, speed and intuitivity of interaction, and visualization quality of results are identified and possible solutions are suggested. This includes a flexible virtual hand interaction with adjustable finger size. In particular a level of detail technique for finite element data based on element shape functions is presented which can greatly improve visualization quality as compared to common visualization approaches. This level of detail technique provides a flexible tool to adjust the exactness of visualization to rendering time (i.e., degree of interactivity) constrains. The concepts are currently being implemented within a testbed called VEIFEL (Virtual Environment Investigation of Finite ELement data). A report of this work and of resulting experiences is given.
