On the optimization of fluid film bearings

In a classical paper slightly after the turn of the century, Lord Rayleigh obtained the optimum one dimensional slider bearing profile, the Rayleigh step. His criteria for optimality was that the load capacity per unit length of the bearing be maximum among all profiles having a given minimum film thickness. Since Rayleigh, an open question has been the determination of the optimum two dimensional bearing profile based on the same criteria as above. In this paper we propose a method for answering that question using algorithms which we have recently developed for this class of problems.
Game-Based Channel Access for AoI-Oriented Data Transmission Under Dynamic Attack

Efficient grant-free uplink transmission is critical in minimizing Age of Information (AoI) in multichannel Internet of Things (IoT) networks. But less attention has been paid to this topic especially when dynamic channel access attacks (DCAAs) exist. To bridge this gap, this article formulates the distributed channel access problem in AoI-oriented IoT networks, and then a reinforcement learning-based solution is put forward based on the theoretical results of the game theory. First, a utility maximization problem is formulated for each sensor node based on its average AoI under DCAAs with probabilistic ACK feedback. Second, the problem is transformed into two ordinary potential game (OPG) models, which are both proved to have at least one nash equilibrium (NE); and a distributed learning algorithm is proposed to reach the NE. Finally, extensive simulations are conducted to evaluate the proposal’s performance. Simulation results verify the effectiveness of the proposed algorithm in various parameters settings.
BIM and Parametric Design in Academia and Practice: The Changing Context of Knowledge Acquisition and Application in the Digital Age

This paper explores the consequences of the use of Building Information Modeling (BIM) and Parametric Design on contemporary architectural practice and associated changes to the roles and responsibilities therein. Knowledge changes associated to new skill-sets of young graduates and their positioning among experienced professionals will be analysed. On one hand the paper will scrutinise how the use of BIM and Parametric design challenges design and delivery of projects, on the other hand the paper will reflect on the extent academic institutions can or should respond to the challenges. What are the opportunities inherent to these changes in practice? How should they influence current academic curricula that include computational design and digital architecture? Based on targeted interviews with recent graduates who entered practice, a number of responses to the challenges and opportunities will be presented by the author for further consideration.
Journal of Homeland Security and Emergency Management Homeland Security Administration and Finance : A Survey of Texas County Officials

This article examines homeland security administration and finance in Texas county governments in the United States. A survey was conducted in the spring of 2006 to determine the extent of funding sources for homeland security and the perception by county officials on the effectiveness of financing homeland security. First, the results of this study indicate that as the size of the county government increases this impacts various aspects of homeland security finances. Second, county officials have indicated that increased funding for homeland security will come from existing revenue sources; raising property taxes is not a feasible option. Finally, there is a belief by county officials that there has not been a radical change in the existing county budget as a result of homeland security initiatives. Counties feel that they are well prepared in their financial management systems to deal with a possible terrorist attack.
CD127 expression in peripheral T cells of pediatric kidney transplant recipients

Introduction: Regulatory T cells (Treg) are emerging as a potential therapy to facilitate long-term allograft survival what makes identification of reliable surface markers that are selectively expressed on Treg is crucial. The aim of this study is to evaluate the regulatory and suppressive functions of CD127 in peripheral T lymphocytes of pediatric kidney transplant recipients through studying the association their frequency and the development of rejection. Material and methods: Flow cytometric analysis of peripheral blood samples for the CD127 surface marker of 50 pediatric transplant recipients and 12 healthy controls was done. Clinical, laboratory, immunosuppressive therapy data and graft function of transplant recipients were collected and correlated with their CD127 peripheral blood expression. Results: CD127 expression in transplanted children was significantly elevated than that of controls (2.76 ±3.26% vs. 0.95 ±0.94%, p = 0.042). CD 127 expression did not correlate with donor relation, cytomegalovirus infection, acute rejection episodes or type of immunosuppressive drugs (p = 0.475, 0.479, 0.678 and 0.333 respectively). Patients with chronic allograft dysfunction (CAD) had significantly lowered frequencies of CD127 compared with those with stable graft function (0.61 ±0.549% vs. 3.08 ±3.375 %, p = 0.021). Conclusions: CD127+ cells is more expressed in transplanted children with stable graft function than those with CAD which makes the regulatory role of CD127+ cells post-transplantation a subject for further researches. The negative relationship between the frequency of CD127 and CAD supposes these cells as probable candidates for allowing allograft survival.
Emotional Intelligence and Its Relationship with Demographic Variables and Job Satisfaction: A Study Among University-Level Teachers in Nepal

Growth and yield parameters of maize and egusi melon in intercrop as influenced by the cropping system and different rates of NPK fertilizer

The effect of different rates of NPK 20:10:10 fertilizer on the growth and yield of egusi melon (Colocynthis citrullus L. Schrad)/maize (Zea mays L.) intercropping system were examined in 2011 and 2012 cropping seasons. Maize and egusi melon were planted sole, and also in intercrop: the maize and egusi melon constituted the main plot treatment while the sub plot was different fertilizer rates (0, 200, 400 and 600 kg/ha). Intercropping reduced the grain yield of maize and the seed yields of egusi melon. Application of 200 kg/ha NPK 20:10:10 fertilizer significantly (P = 0.05) promoted the yield of maize and egusi-melon. The competitive abilities of the component crops were enhanced at increased fertilizer application rate. The total LER in all intercropping situations were greater than one, indicating that the two crops in mixture were able to utilize the growth factors maximally for their optimum yield and productivity.
THE THERMODYNAMIC BASIS OF PULSED DETONATION ENGINE THRUST PRODUCTION

In recent years, several papers have been published comparing the detonative engine thermodynamic cycle with the classical Brayton cycle. While these papers appear to be converging on an industry-accepted thermodynamic model for the Pulsed Detonation Engine, PDE, total convergence has not yet occurred. This paper attempts to assist in the convergence by applying analysis to representative trajectories, fuel-to-air ratios, and component efficiencies. It is found that global conservation of energy for the post-detonative state provides a representative condition from which to compute nozzle expansion losses.
Three-Dimensional Conjugate Heat Transfer Simulation of an Internally-Cooled Gas Turbine Vane

A conjugate numerical methodology was employed to predict the metal temperature of a three-dimensional gas turbine vane at two different engine-realistic operating conditions. The vane was cooled internally by air flowing through ten round, radially-oriented channels. The conjugate heat transfer approach allows the simultaneous solution of the external flow, internal convection, and conduction within the metal vane, eliminating the need for multiple, decoupled solutions, which are time-consuming and inherently less accurate when combined. Boundary conditions were specified only for the inlet and exit of the vane passage and the coolant channels, while the solid and fluid zones were coupled by energy conservation at the interfaces, a condition that was maintained throughout the iterative solution process. Validation of the methodology was accomplished through the comparison of the predicted aerodynamic loading curves and the midspan temperature distribution on the vane external surface with data from a linear cascade experiment in the literature. The superblock, unstructured numerical grid consisted of nearly seven million finite-volumes to allow accurate resolution of flowfield features and temperature gradients within the metal. Two models for turbulence closure were used for comparison: the standard k-e model and a realizable version of the k-e model. The predictions with the realizable k-e model exhibited the best agreement with the experimental data, with maximum differences in normalized temperature of less than ten percent in each case. The present study shows that the conjugate heat transfer simulation is a viable tool in gas turbine design, and it serves as a platform on which to base future work with more complex geometries and cooling schemes. © 2003 ASME
Marine Macroalgae Diversity at Bhuigaon Coast, District Palghar, Maharashtra

126 DOI: 10.37398/JSR.2021. 650621 Abstract: Algal biodiversity is dynamic and varies a lot from region to region, coast to coast and time to time. This biodiversity and intertidal zonal distribution study was carried out at a small coastal area away from the regular tourist zones near metropolitan Mumbai area, at Bhuigaon in Palghar district of Maharashtra. The study gives input in the distribution pattern of different division of algae with respect to different intertidal zones of sea area. The study indicated that the high tide zone and the middle tide zones of the coastal rocky beach is the site of maximum algae occurrence with 35 % and 40 % occurrence percentage. The study also indicated this zone to be very rich in members of Rhodophyta as total 8 genera are found to be present here. Enteromorpha, a member of Chlorophyta was the only most frequent genera with a frequency of 75%. It was observed that algae are very specific in their occurrence at specific zones in the intertidal coastal area. As many as 11 genera of total 15 had least frequency of 25% and presence in only one of the zones specific for their growth and development.
SERAT PANGAN (DIETARY FIBER) DAN MANFAATNYA BAGI KESEHATAN

Serat pangan, dikenal juga sebagai serat diet antara dietary fiber, merupakan bagian dari tumbuhan yang dapat dikonsumsi dan tersusun dari karbohidrat yang memiliki sifat resistan terhadap proses pencedrnaan dan penyerapan di usus halus manusia serta mengalami fermentasi sebagian atau keseluruhan di usus besar. Jadi serat pangan merupakan bagian dari bahan pangan yang tidak dapat dihirolisis oleh enzim-enzim pencernaan. Sayur-sayuran dan buah-buahan merupakan sumber serat pangan yang sangat mudah ditemukan dalam bahan makanan. Akhir0akhir ini adanya perubahan pola konsumsi pangan di Indonesia menyebabkan berkurangnya konsumsi sayuran dan buah-buahan hasil penelitian dan kajian diikuti juga terjadinya pergeseran atau perubahan pola penyakit-penyakit infeksi menjadi penyakit-penyakit degeneratif dan metabolic. Secara nyata dialami masyarakat perkotaan yang sebagian masyarakatnya negitu mobil dan sibuk cenderung mengkonsumsi makanan siap saji dan terjadi pergeseran pola makan dari tinggi kabohidrat, tinggi serat dan rendah lemak ke pola konsumsi rendah kabohidrat dan rendah serat, tinggi lemak dan tinggi protein. Hal inilah yang menyebabkan tingginya kasus penyakit-penyakit seperti jantung coroner, kanker kolon (usus besar), dan penyakit degenerative lainnya di Indonesia. Meskipun tidak mengandung zat gizi, serat pangan menguntungkan bagi kesehatan yaitu berfungsi mengontrol berat badan atau kegemukan (obesitas), penanggulangan penyakit diabetes, mencegah gangguan gastrointestinal, kanker kolon, serta mengurangi tingkat kolesterol darah dan penyakit kardiovaskuler. Merkipun serat pangan memberikan efek positif terhadap kesehatan, namun juga memberikan efek negative, sehingga serat pangan tidak boleh di konsumsi secara berlebihan, sehingga acuan kebutuhan serat yang dianjurkan yaitu 30 gram/hari.
Efficacy of hydroxychloroquine in the prevention of thromboembolic events: A systematic review and meta-analysis

Objective To estimate the risk ratio (RR) of thromboembolic events in chloroquine and hydroxychloroquine users compared to non-users. Methods We systematically reviewed randomized controlled trials (RCTs), using MEDLINE and EMBASE databases from inception to the present, reporting thromboembolic events in chloroquine and hydroxychloroquine users compared to non-users. Four authors independently screened all the records obtained through our search strategy and later revised the selected full-text articles for eligibility, according to our inclusion criteria. The same four authors independently extracted relevant data through a customized data collection form while two other authors assessed the quality of the included RCTs using the Cochrane risk-of-bias tool (Version 2.0). All the disagreements were resolved through discussions among the authors. We calculated the risk ratio (RR) and its respective standard error of developing thromboembolic events in hydroxychloroquine users and non-users for each individual study and pooled the results using a random effects model meta-analysis. We assessed Heterogeneity using the Tau2 and I2, and publication bias using funnel plotting and Egger’s regression. The protocol for this systematic review is registered at the PROSPERO database (CRD42021247902). Results Thirteen RCTs met our eligibility criteria and were included in our analysis (2663 patients). We found that hydroxychloroquine—no study on chloroquine was found—reduced the risk of thromboembolic events by 49% (RR 0.51[IC 95% 0.31–0.84]) with a medium heterogeneity (I2 = 67% and T2 = 0.4948). We did find some asymmetry in the inspection of the funnel plot, which was ruled out through an Egger’s regression (p-value = 0.1025). Conclusion Our data reinforce the idea that hydroxychloroquine reduces the risk of thromboembolic events.
Effect of tillage and pre-mix application of herbicides on weed growth and productivity of late-sown wheat

Wheat (Triticum aestivum) is the second most important crop in India whereas in West Bengal, its share of total cultivated land is very limited. Total area and production of wheat during 2017-18 has been reported to be 29.58 million ha and 99.70 million tonnes, respectively with a productivity of 3.3 t/ha in India (DAC&FW, 2018). Zero tillage is becoming popular because of its suitability in rice-wheat cropping system. Diversified weed flora causes severe yield loss in wheat. Pre-mixed broad-spectrum herbicide is cost-effective against complex weed flora. Hence, the present experiment was conducted to study the effect of tillage and weed management on weed growth, productivity and profitability of late sown wheat in the sub-humid red and lateritic agroecological zone of the tropics using different doses of premix herbicide i.e . sulfosulfuron-ethyl + metsulfuron-methyl and clodinafop-propargyl + metsulfuron-methyl.
Multimetric Monitoring of a Historic Swing Bridge

The Rock Island Arsenal Government Bridge, built over the Mississippi River in 1896 between Rock Island, IL and Davenport, IA, is just one of over two hundred bridges owned by the United States Army. The swing span of the Rock Island Arsenal Government Bridge has the ability to rotate 360° in either direction and can lock each end of the span on either abutment. The bridge carries highway and rail traffic; the swing span allows for the passage of barge traffic on the river. The Army regularly inspects and maintains their bridges to ensure their functionality. To supplement the regular inspections of the swing span of the Government Bridge, the US Army Engineering Research and Development Center (ERDC) has installed a structural health monitoring system composed of both a fiber optic sensor network and a wireless smart sensor network. This multi-framework system measures strain, acceleration, and orientation and uses these metrics to perform structural health monitoring of the bridge. The monitoring is designed to automatically record the measured changes in strain caused by swing events and record the accelerations measured during train events and other scheduled times of day. The integrated monitoring system has been successful in recording the necessary multimetric sensor data and using it to monitor the swing span of the Government Bridge.
Using of Some Antioxidants for Cotrolling of Mosaic Causing Viruses on Vegetables In Minia Governorate, Egypt.

In previous works, it has been reported that three viruses affecting some economic vegetable crops and causing severe losses in yield.These viruses, were cucumber mosaic virus (CMV), hibiscus chlortic ringspot virus (HCRSV) and potato virus Y (PVY) . The effect of aquaeous extracts of some medicinal plants on diseases caused by these viral was reported in previous paper ( Saleh et al . , 2019 ) . This paper delt with the effect of some antioxidants in cotrolling these virus diseases. The antioxdants are ascorbic, benzoic, citric, and salycylic acids at different concentration (50, 100, and 200 ppm). Application , of some antioxidants either as soaking host seeds or spraying before inoculation have marked inhibitory effect and reduced disease infection and alleviated symmptoms particularly at older ages.
From Models to Code and Back : A Round-trip Approach for Model-driven Engineering of Embedded Systems

The complexity of modern systems is continuously growing, thus demanding novel powerful development approaches.In this direction, model-driven and component-based software engineering have reached the status of promising paradigms for the development of complex systems. Moreover, in the embedded domain, their combination is believed to be helpful in handling the ever-increasing complexity of such systems.However, in order for them and their combination to definitively break through at industrial level, code generated from models through model transformations should preserve system properties modelled at design level.This research work focuses on aiding the preservation of system properties throughout the entire development process across different abstraction levels. Towards this goal, we provide the possibility of analysing and preserving system properties through a development chain constituted of three steps: (i) generation of code from system models, (ii) execution and analysis of generated code, and (iii) back-propagation of analysis results to system models.With the introduction of steps (ii) and (iii), properties that are hard to predict at modelling level are compared with runtime values and this consequently allows the developer to work exclusively at modelling level thus focusing on optimising system models with the help of those values.
