Isothermal Elastohydrodynamic Lubrication of Point Contacts: Part III—Fully Flooded Results

Procedures outlined by the authors in an earlier publication (1976) on theoretical formulation for isothermal elastohydrodynamic lubrication of point contacts are used to assess the influence of the ellipticity parameter and the dimensionless speed, load, and material parameters on minimum film thickness. Conditions equivalent to using solid materials of bronze, steel, and silicon nitride, and lubricants of paraffinic and naphthenic mineral oils are considered in obtaining the exponent on the dimensionless material parameter. Thirty-four different cases are used to generate the fully flooded film thickness formula. A fully flooded condition is said to exist when the inlet distance of the conjunction ceases to influence in any significant way the minimum film thickness. Contour plots are also shown that indicate in detail the pressure spike and two side lobes in which the minimum film thickness occurs.
Effects of Musculoskeletal and Sensory Degradation Due to Aging on the Biomechanics of Slips and Falls

A laboratory study was conducted to examine the initiation and recovery from foot slips among different age groups utilizing biomechanical parameters, muscle strength, and sensory measurements. Forty two subjects from three age groups (young, middle, and elderly) walked around a circular track at a comfortable pace, while carrying a light load and while unloaded. Slippery floor surfaces were placed on the track over force platforms at random intervals. The results indicated that younger subjects slipped as often as elderly subjects, however, the recovery process of older individuals was much slower and less effective. The ability to successfully recover from a slip (thus preventing a fall) is believed to be affected by lower extremity muscle strength and sensory degradation of the elderly individuals.
COVID-19 and Pandemic Preparedness: Foresight Narratives and Public Sector Responses

The management of the COVID-19 pandemic is a novel global challenge being addressed in real time. While some countries and regions of the world have had more recent experience managing similar viruses (such as SARS), all have had to deal with the new corona virus and the novel challenges that it presents. Public policy responses are rapidly changing, sometimes daily. This article focuses on how foresight narratives have impacted policymaking as related to the COVID-19 pandemic. More specifically, it provides an overview of the use of foresight within the public sector prior to the pandemic. It also investigates the key narratives in circulation during the implementation of governments' strategic objectives and the realization of visions of a 'pandemic-free' society. The approach used here is that of narrative foresight which predominantly focuses on the stories that individuals, organizations, states and civilizations tell themselves about the future. In addition to the overarching narratives, the article also investigates more specifically the most commonly used metaphors prior to and during the COVID-19 pandemic. The goal of the article is to ascertain which lessons we can learn in terms of successes and failures of narrative foresight in action', so as to be able to utilise this knowledge for future global problems. Finally, the article argues that many current metaphors and narratives are linked to 'futures fallacies' - detrimental thinking patterns about the future. It then concludes by briefly investigating alternative narratives and metaphors which are more likely to facilitate the desired future of adequate pandemic preparedness.
Electron irradiation effects in polyimide passivated InP/InGaAs single heterojunction bipolar transistors

In this paper, we report the effects of high-energy electron irradiation on the DC characteristics of polyimide passivated InP/InGaAs single heterojunction bipolar transistors. In contrast with the results of electron irradiation of unpassivated devices, the polyimide-passivated devices show much less degradation of current gain and no change in the collector output conductance. The decrease of collector current in the active regime is found to be typically /spl sim/ 9 percent for a cumulative equivalent 1-MeV dose of 2.7/spl times/10/sup 16/ e/cm/sup 2/ (/spl sim/620 Mrad (InGaAs)). For low base currents, the devices show an increase in the current gain for smaller doses (<2.5/spl times/10/sup 15/ e/cm/sup 2/) followed by a decrease at the higher doses. The increase in the current gain at low doses is attributed to the trapped charge in the polyimide layer near the periphery of the B-E junction. The most significant effect of electron irradiation on the passivated devices is a-decrease in the slope of the I/sub C/-V/sub CE/ characteristics of some devices in the saturation regime. We believe this decrease in slope is caused by an increase in the collector series resistance after irradiation. Finally, devices with smaller emitter size are shown to have less radiation degradation than the larger emitter devices. This is explained by the smaller radiation damage at the junction peripheries of the passivated devices.
Reproduction cycle of Longtail shad (Tenualosa macrura) in Bengkalis Waters, Riau, Indonesia

Tenualosa macrura is an endangered fish in Riau Province, which is classified as a protected fish. Therefore, the first step is to study the reproductive cycle, aiming o prevent these species from extinction. The observation was carried out for 13 months from January 2019 to February 2020 (except February 2019) in Indonesia's Bengkalis waters. This study's purpose was determined to determine the spawning season, fecundity, and behavior of this species. The results showed that the relationship between length and weight positively correlates with the length-weight of male T. macrura (R² = 0.84) and female (R² = 0.67), while the length-weight of all males and females were reported to be (R² = 0.95). Meanwhile, the relationship between fecundity and length-weight has no relationship. Furthermore, the spawning season lasted all through the year, and it occurred at every low tide (dark moon) and high tide (full moon). Despite being discovered occasionally in a limited amount, the greatest amount of T. macrura was reported between July and September each year.
Determination Factors Associated with Immune Responses Towards First Dose Edmonston-Zagreb (EZ) Measles Vaccine in Indonesian Infants

Background: Measles outbreaks under high coverage of measles vaccination in Indonesia is gaining a necessary evaluation of factors associated with measles-vaccine immune responses. Objctive: The purposes of recent study were to evaluate the association of sociodemographic and anthropometric parameters and specific immune responses towards first dose Edmonston-Zagreb (EZ) measles vaccine in Indonesian infants. Methods: A total of 35 infants were enrolled in this cohort study. Measles immune responses were followed up at one and six months after vaccination then analyzed for its association with sociodemographic, anthropometric, and nutritional parameters. The plaque-reduction microneutralization assay was conducted to measure the titer of measles specific IgG antibody. The level of CD4+ and CD8+ T-cells that exhibiting gamma interferon (IFN-γ) secretion were analyzed by flow cytometry. The association between variable was analyzed by linear regression. The difference immune response among variable were analyzed with Mann-Whitney test. Results: Vitamin A supplementation and breastfeeding were predicted as associated factor for humoral and cellular immune response after one month and six months measles vaccination among Indonesia Infants. Conclusion: Nutritional factor is associated with measles vaccination immune response in Indonesian infants.
Position-Mode Haptic-Based Control of Teleoperated Hydraulic Actuators

A control scheme for teleoperation of hydraulic actuators, using a haptic device, is developed and experimentally evaluated in this paper. In the control laws, the position error between the displacement of the haptic device and the hydraulic actuator movement is used at both master and slave sides to maintain good position tracking at the actuator side while providing a haptic force to the operator. Lyapunov’s stability theory and LaSalle’s invariant set theorems are employed to prove the asymptotic stability of the system. It is shown that beside stability, the system performs well in terms of position tracking of the hydraulic actuator and providing a feel of telepresence to the operator. Proposed controller only needs system’s pressures and displacements that are easy to obtain via on-line measurements. Additionally, the controller does not need any information about the parameters of the system. These characteristics make the controller very attractive from the implementation view point.Copyright © 2011 by ASME
Delay-Aware Priority Access Classification for Massive Machine-Type Communication

Massive Machine-type Communications (mMTC) is one of the principal features of the 5th Generation and beyond (5G+) mobile network services. Due to sparse but synchronous MTC nature, a large number of devices tend to access a base station simultaneously for transmitting data, leading to congestion. To accommodate a large number of simultaneous arrivals in mMTC, efficient congestion control techniques like access class barring (ACB) are incorporated in LTE-A random access. ACB introduces access delay which may not be acceptable in delay-constrained scenarios, such as, eHealth, self-driven vehicles, and smart grid applications. In such scenarios, MTC devices may be forced to drop packets that exceed their delay budget, leading to a decreased system throughput. To this end, in this paper a novel delay-aware priority access classification (DPAC) based ACB is proposed, where the MTC devices having packets with lesser leftover delay budget are given higher priority in ACB. A reinforcement learning (RL) aided framework, called DPAC-RL, is also proposed for online learning of DPAC model parameters. Simulation studies show that the proposed scheme increases successful preamble transmissions by up to $75 \%$ while ensuring that the access delay is well within the delay budget.
Pesticide and Nutrient Loads of Lake Bosomtwe in the Ashanti Region of Ghana

Pollution of Lake Bosomtwe is a major concern in Ghana due to its derived so-cio-economic benefits such as employment, ecotourism and major protein source to the people in the basin. Besides these benefits, the lake water is used for domestic purposes and has since served as the drinking water source to the people. However, the use of agrochemicals within the basin has intensified within the last decade. The problems associated with fertilizer and pesticide use in the Bosomtwe basin seem to carry with it a higher price, which, if not identified and checked, will overshadow the desired benefits of the lake. This study assesses pesticide and nutrient loads of Lake Bosomtwe in the Ashanti Region of Ghana. Fifty-four (54) lake water samples were collected from September 2016 to February 2017. Pesticide samples were extracted using the solid phase extraction method and GCMS to identify the pesticides present in the water samples and determine their loads. The data obtained were analyzed using Statistical Product Service Solutions (SPSS version 20) for descriptive statistics. The concentration of dichlorvos was
An optimised dynamic bottleneck dispatching policy for semiconductor wafer fabrication

A dynamic bottleneck dispatching (DBD) policy is designed in this paper to detect bottlenecks in a timely way and make adaptive dispatching decisions of semiconductor wafer fabrication systems according to the real-time conditions. Control parameters of the proposed DBD algorithm are optimised by response surface methodology (RSM) and desirability functions. Numerical results show that DBD outperforms common scheduling rules such as CR + FIFO, EDD, SRPT, SPT, SPNB and an existing dynamic bottleneck dispatching method.

Stochastic modelling of water temperatures in a small stream using air to water relations

Stream water temperature is a very important parameter when assessing aquatic ecosystem dynamics. For instance, cold-water fishes such as salmon can be adversely affected by maximum summer temperatures or by those exaggerated by land-use activities such as deforestation. The present study deals with the modelling of stream water temperatures using a stochastic approach to relate air and water temperatures in Catamaran Brook, a small stream in New Brunswick where long-term multidisciplinary habitat research is being carried out. The first step in the modelling approach was to establish the long-term annual component (pattern) in stream water temperatures. This was possible by fitting a Fourier series to stream water temperatures. The short-term residual temperatures (departure from the long-term annual component) were modelled using different air to water relations, namely a multiple regression analysis, a second-order Markov process, and a BoxnJenkins time-series model. The results indicated that it was possible to predict daily water temperatures for small streams using air temperatures and that the three models produced similar results in predicting stream temperatures. The root mean square error (RSME) varied between 0.59∞C and 1.68∞C on an annual basis from 1990 to 1995, with the warmest year (1994) showing the highest RMSE. Although 1992 was an exceptionally cold summer (coldest in 30 years), good predictions of stream water temperature were obtained, with an RMSE of approximately 1.24∞C. Of the three models, the second-order Markov process was preferred based on its performance and its simplicity in development.
Conducting Spheres in Rectangular Waveguides

A conducting sphere on the center of the broad wall of a rectangular waveguide causes frequency independent reflections for a wide range of frequencies. This empirically found behavior is confirmed analytically here by perturbational calculations. Furthermore experimental and analytical resufts are given for a sphere located in the middle of the waveguide cross section.
Prevalence and correlates of poor sleep quality in chronic liver disease patients

ABSTRACT Introduction: Previously done studies have shown that 39.6%-81% of subjects with chronic liver disease (CLD) report poor sleep quality and 42% experience insomnia. However, despite the high prevalence of insomnia and poor sleep quality in this group of patients, literature is scanty. In addition, previous studies have not ruled out subjects with restless legs syndrome, which is seen in a sizable number of subjects having CLD. Material and Methods: Adult patients with a clinical diagnosis of CLD were included after excluding potential confounders. The etiology of CLD was investigated. The severity of liver disease was assessed and graded as Child-Turcotte-Pugh (CTP) class A, B or C; model for end-stage liver disease (MELD) score and as the presence of compensated or decompensated liver disease. Acute on chronic liver failure was also defined as per APASL criteria. For the present study, subjects having a score greater than 14 on insomnia severity index along with clinical diagnosis (DSM-5) were considered as having insomnia. Depression was diagnosed using a patient health questionnaire (PHQ-9) along with clinical criteria following DSM-5. Sleep quality was assessed by the Pittsburg sleep quality index - Hindi version. RLS was diagnosed on clinical interview and examination. The severity of RLS was assessed using international RLS severity rating scales. Results: This cross-sectional study included 131 subjects. This sample had a predominance of males (78.6%), the average age of subjects was 48.70+12.31 years and 98.5% of subjects had decompensated liver disease. 54.2% had a history of alcohol use disorder and 45% had a history of nicotine use disorder. The prevalence of hepatitis B and C infection was 16.8% and 23.7%, respectively. Acute on chronic liver failure was observed in 22.9% of subjects. 19.8% of subjects had acute kidney injury. Poor sleep quality was reported by 37.4% of subjects in this study which was higher than population prevalence (p<0.001). Subjects with poor sleep quality had a higher proportion of insomnia, RLS, and depression. 19.8% of subjects reported insomnia in the present study and depressive symptoms were more severe among subjects with insomnia. RLS was reported by 19.1% of subjects and 2.3% had a positive family history of RLS. However, there was no difference in sleep quality and insomnia in patients with or without RLS. Conclusion: The present study shows that insomnia and poor sleep quality are more prevalent among patients with CLD. Sleep disturbance is associated with depressive symptoms and can worsen the quality of life.
A dual continuum coupled multiphase flow model with mixed second order wáter transfer for structured soils, part II: testing with synthetic cases and application to a real experiment

The dual porosity model presented in part I (Zheng and Samper, 2005) of this series of two papers is tested here. Numerical solutions of the second order term are compared with reference results obtained with both 1-D and 2-D single domain models. The dual domain model reproduces accurately the transfer term when the scaling term is properly estimated. Estimated value is around 0.8 for bentonite. The water transfer term by chemical osmosis is significant when there is a large geochemical non- equilibrium betweenn macro and micro domains. A dual- domain model is used to interpret the FEBEX 'mock-up' test, a long-term full-scale thermal hydration test of the compacted bentonite barrier. Optimum values of scaling term and weighting factor for bentonite are estimated by an inverse algorithm based on measured inflow data. Agreement between computed and measured water inflows improves when the dual continuum model is used.
COVID-19 Acute Kidney Injury: Current Knowledge and Barriers of Research

Page 1 of 3 COVID‐19 has accounted for over 2.4 million fatalities worldwide (Coronavirus Resource Center, Johns Hopkins University, February 2021). The disease is caused by the infection of a novel coronavirus, named severe acute respiratory syndrome coronavirus‐2 (SARS‐CoV‐2). While the upper respiratory airways serve as a port of entry for viral infection, SARS‐CoV‐2 has broad tropism owing to the presence of its cellular receptor angiotensin‐converting enzyme‐2 (ACE2) and the cellular transmembrane protease serine 2 (TMPRSS2) required for viral S activation on a large number of tissues including heart, brain, intestines, and kidneys. Because of the systemic tropism, infection with SARS‐CoV‐2 leads to a wide spectrum of clinical presentations. The severity of the disease ranges from asymptomatic to mild and from self‐limited symptoms to severe acute respiratory distress syndrome and death. A hyperinflammatory state and cytokine release syndrome (“cytokine storm”) have been described as characteristics of the severe COVID‐19 and this is associated with multiorgan failure. [1,2]
Development of a computer model for prediction of collision response of a railroad passenger car

The paper describes the development of a detailed finite element model that is capable of predicting the response of a rail passenger car to collision conditions. This model was developed to predict the car crush, the three-dimensional gross motions of the car, and the vertical, lateral, and longitudinal accelerations experienced by the car during collisions. The finite element model developed was for a Pioneer passenger coach car. This vehicle was used in a single car impact test. The model was then used to simulate the test and the results are compared to the test data.
Macroscale assessment of low‐velocity impact on hybrid composite laminates

Composites are usually brittle materials and have low impact properties. Structural dimensions, stacking sequence, ply materials, ply thicknesses and ply angles are standard variables that influence composite‘s performance against impact loads. Stacking sequence in hybrid laminates affects the failure and impact resistance. Failure mechanisms at the low‐velocity impact of a rigid object in hybrid laminates are complex, and the subsurface damage in a composite laminate cannot be detected directly. However, various simulation platforms make it easy to see the impact damage between the plies of laminate. This paper numerically investigated the effect of stack sequence and hybridization of two fiber types against low‐velocity impact. The current study adopted four‐layer composite laminates of carbon and glass fiber layers with a stacking plan [C/C/C/C], [C/G/C/G] and [G/C/G/C], having lay‐up angles as [0°/45°/−45°/90°]. Keeping the impactor mass and the incident velocity constant, the laminates were subjected to low‐velocity impact. The damage contours for a failure mode were recorded and compared at the ply level. The numerical study resulted in impact imitations showing comparisons of the damage contours using Hashin failure criteria. Hybrid laminates display better performance in absorbing impact energies; however, hybrid laminates experienced more subsurface damage due to more impact energy absorption.
Literature translated from Dutch in the Czech publishing house Družstevní práce during the Nazi occupation

Družstevní práce (Cooperative Labour, hereafter DP) was among the most important Czech publishing houses. As it was a joint venture of readers, editors and publishers, it survived even after the communist law on the publishing and distribution of books liquidated most pri vate publishers.1 Nevertheless, DP was gradually suppressed until the publishing concession was cancelled in 1952. Fortunately, a considerable part of its archive is preserved in the National Literary Archive in Prague (Literární archiv Památníku národního písemnictví, LA PNP). Among these are the minutes of DP’s editorial board, plans, and correspondence with Czech authorities (Knap 1971, 2, 197), giving us insight into discussions about foreign literary works proposed for publication. This article demonstrates how proposed translations from Dutch were treated by the board depending on the current political situation. After a survey of DP’s history and a sketch of the political situation in the 1930s and 1940s, a short survey of the development of Czech translations from Dutch will be provided. Dutch and Flemish literary works served as a literary “escape route” for publishers unwilling to publish Nazi-friendly literature during the World War II. Usually DP returned rejected materials to the writers or foreign publishers, but some complete translations are preserved in the archives, which were postponed for publication until after the liberation of Czechoslovakia or were never published at all. The attack on the Deputy Reich Protector Reinhard Heydrich in May 1942 and the consequent Nazi retaliation on the Czech population (the so-called Heydrichiade) were also a turning point for Czech translations of foreign literature.
