Numerical Study of Interaction Between NPP Containment Atmosphere and Passive Autocatalytic Recombiners

The interaction of a nuclear power plant containment atmosphere with a Passive Autocatalytic Recombiner (PAR) was simulated using the Computational Fluid Dynamics code CFX4.4. The main purpose of the simulation was to observe containment atmosphere mixing phenomena, influenced by the PAR, during a postulated severe-accident scenario. A two-dimensional geometrical model of the simulation domain was developed. The containment was represented by an adiabatic rectangular box with a PAR situated at an intermediate elevation near a wall. The flow in the simulation domain was modelled as singlephase and the turbulence was modelled with a Menter modified low-Reynolds k-e model. The results of the simulation are presented and analysed.
Concomitant Hepatic Artery Resection for Advanced Perihilar Cholangiocarcinoma: A Narrative Review

Simple Summary In the eighth edition of their cancer classification system, the Union for International Cancer Control (UICC) defines contralateral hepatic artery invasion as T4, which is considered unresectable as it is a “locally advanced” tumour. However, in the last decade, several reports on hepatic artery resection (HAR) for perihilar cholangiocarcinoma (PHCC) have been published. The reported five-year survival rate after HAR is 16–38.5%. Alternative procedures for the treatment of HAR have also been reported. In this paper, we review HAR for PHCC, focusing on its history, diagnosis, procedures, and alternative procedures. Abstract Perihilar cholangiocarcinoma (PHCC) is one of the most intractable gastrointestinal malignancies. These tumours lie in the core section of the biliary tract. Patients who undergo curative surgery have a 40–50-month median survival time, and a five-year overall survival rate of 35–45%. Therefore, curative intent surgery can lead to long-term survival. PHCC sometimes invades the surrounding tissues, such as the portal vein, hepatic artery, perineural tissues around the hepatic artery, and hepatic parenchyma. Contralateral hepatic artery invasion is classed as T4, which is considered unresectable due to its “locally advanced” nature. Recently, several reports have been published on concomitant hepatic artery resection (HAR) for PHCC. The morbidity and mortality rates in these reports were similar to those non-HAR cases. The five-year survival rate after HAR was 16–38.5%. Alternative procedures for arterial portal shunting and non-vascular reconstruction (HAR) have also been reported. In this paper, we review HAR for PHCC, focusing on its history, diagnosis, procedures, and alternatives. HAR, undertaken by established biliary surgeons in selected patients with PHCC, can be feasible.
Solving the heliogyro’s inverse problem

A heliogyro is a solar sail concept that divides the solar sail membrane into a number of long, slender blades of film extended from a central hub, maintained in a flat state through spin-induced tension. The heliogyro can redirect and scale the solar radiation pressure (SRP) force and can achieve attitude control by twisting the blades, similar to a helicopter rotor. Different pitch profiles exist, including pitching the blades in a collective, cyclic or combined collective and cyclic manner. While the forward mapping, i.e., computing the SRP force and moment generated by the heliogyro for a given pitch profile, is straightforward, the inverse of the problem is much more complex. However, this inverse problem (finding the blades’ pitch that results in a desired SRP force and/or moment) is crucial for heliogyro mission design and operations. This paper therefore solves the inverse problem numerically: first, only for a desired SRP force or SRP moment and subsequently for the fully coupled inverse problem. The developed methods are subsequently applied to track a reference trajectory that corrects for injection errors into a solar sail Sun-Earth sub-L1 halo orbit. I. Introduction
Revisiting the Four Types of Cyclists: Findings from a National Survey

To understand the makeup of a population in terms of how people view bicycling can help in planning bicycle facilities and programs. Roger Geller, bicycle coordinator for the City of Portland, Oregon, proposed a typology that characterized people as one of four types—strong and fearless, enthused and confident, interested but concerned, and no way, no how—with respect to their attitudes toward bicycling. The research presented here sought to find out how applicable the typology was nationally and explored motivating factors, barriers, and the appeal of various bicycle facility types for each type of cyclist or potential cyclist. This study followed up on an earlier study that tested Geller’s typology with Portland data. In this new study, a sample involved 3,000 adults who lived in the 50 largest U.S. metropolitan areas. On the basis of respondents’ (a) stated level of comfort when they bicycled in different environments, (b) their interest in bicycling, and (c) their recent behavior, the study estimated that about one-third of adults were in the no way, no how group, and about half were in the interested but concerned group. The distribution was similar to that of the earlier findings for Portland. Several demographic differences emerged, with women less likely to be enthusiastic and confident or to be interested but concerned. Few differences appeared in whether respondents had ridden a bike at all in the past 30 days. Differences emerged as to where they bicycled and how often. The interested but concerned group was least likely to ride for transportation and rode less frequently. Barriers included not having a bicycle to ride; needing a vehicle for work, school, or other reasons; destinations too far to reach by bicycle; too few bike lanes or trails; and traffic.
EFFECT OF INTEGRATED NUTRIENT MANAGEMENT ON PLANT GROWTH AND SEED YIELD IN HYBRID MAIZE (ARJUN)

An experiment was carried out in RBD design with three replications and nine treatments. Among the treatments, significantly highest plant height (198.9 cm), number of leaves (10.30), leaf area index (2.19), chlorophyll content (54.30), dry matter accumulation (297.1 g plant -1 ) at harvest, cob weight (184.5 g plant -1 ), number of seeds (434.7 seeds cob -1 ), seed weight (130.7 g cob -1 ), shelling percentage (74.7), seed yield (58.36 q ha -1 ) and 100 seed weight (30.27 g) were recorded in T 9 (50 % RDN through VC + 50 % RDF + ZnSO 4 @10 kg ha -1 + Azospirillum @ 500 g ha -1 + PSB @ 500 g ha -1 + FYM @ 10 t ha -1 ). Whereas, lowest plant height (170.4 cm), number of leaves (8.40), leaf area index (1.38), chlorophyll content (43.18) and dry matter accumulation (224.0 g plant-1) at harvest, cob weight (138.9 g plant -1 ), number of seeds (372.4 seeds cob -1 ), seed weight (94.2 g cob -1 ), shelling percentage (62.3), seed yield (41.20 q ha -1 ) and 100 seed weight (24.97 g) were noticed in T2 (50 % RDN through FYM + 50 % RDF). From this study, it can be concluded that among the different treatments T 9 was best to get higher seed yield in hybrid seed production of maize.
Preliminary Report: Controller Prototyping and Validation for Photo-Voltaic Comfort Cooling

Large office buildings typically with glass fronts often suffer from a high cooling demand during summertime. Typically, this requires a large amount of additional electricity for the cooling system. One straightforward alternative is to store cooling energy using electricity generated by solar cells, and this paper investigates, demonstrates and validates the feasibility of providing energy efficient comfort cooling with a low environmental impact, while offering flexibility to the electrical grid. Also, the possibility of reusing unmodified existing CTS systems is investigated. Finally, the possibility of providing improved comfort through intelligent supervisory control is studied. The system is comprised of a grid coupled photovoltaic system, a heat pump, an ice bank and a cooling coil to interface the existing ventilation system in the office building.
Lysosomal dysfunction in Down Syndrome and Alzheimer mouse models is caused by selective v-ATPase inhibition by Tyr682 phosphorylated APP βCTF

Lysosome dysfunction arises early and propels Alzheimer’s Disease (AD). Herein, we show that amyloid precursor protein (APP), linked to early-onset AD in Down Syndrome (DS), acts directly via its β-C-terminal fragment (βCTF) to disrupt lysosomal v-ATPase and acidification. In human DS fibroblasts, the phosphorylated 682YENPTY internalization motif of APP-βCTF binds selectively within a pocket of the v-ATPase V0a1 subunit cytoplasmic domain and competitively inhibits association of the V1 subcomplex of v-ATPase, thereby reducing its activity. Lowering APP-βCTF Tyr682 phosphorylation restores v-ATPase and lysosome function in DS fibroblasts and in vivo in brains of DS model mice. Notably, lowering APP-βCTF Tyr682 phosphorylation below normal constitutive levels boosts v-ATPase assembly and activity, suggesting that v-ATPase may also be modulated tonically by phospho-APP-βCTF. Elevated APP-βCTF Tyr682 phosphorylation in two mouse AD models similarly disrupts v-ATPase function. These findings offer new insight into the pathogenic mechanism underlying faulty lysosomes in all forms of AD.
Populist discourse and the resulting discontent in hybrid regimes: an examination of Rouhani’s rhetoric in the first wave of the COVID-19 pandemic

ABSTRACT This work is an attempt to fill the academic gap that neglects the close reading of speeches of political leaders in non-democratic societies during the COVID-19 pandemic. To this end, this research focuses on the rhetoric of Hassan Rouhani, the former president of Iran, during the first wave of the COVID-19 crisis. Using the two main rhetorical devices of identification and metaphor, this work analyzes all of Rouhani’s speeches from February 2, 2020, to April 27, 2020. In addition, all speeches by three most powerful clerics in Iran, namely Khamenei, Saeidi, and Alamolhoda, and a sample of tweets by Iranian users (1644 in total) were analyzed to understand the extent to which Rouhani’s rhetoric was successful. The results show that Rouhani articulated a populist discourse during the pandemic. In an attempt to break away from hegemonic discourse, he sought to identify his government, rather than the state, with the people to construct a discursive us. Nevertheless, his rhetoric did not go down well with Iranian Twitter users. This study also analyzes Rouhani’s deft juggling act to woo both the populace and the conservative power centers to satisfy them while trying to distance himself from the latter .
Geometric and frequency scalable transistor behavioural model for MMIC design

This thesis presents research in developing and validating scaling in terms of geometry and frequency for Behavioural models in order to extend their functionality. Geometric and frequency scalability, once thought to be limited only to Physical and Compact models, greatly reduces the number of measurements for model generation. Besides saving precious time and effort, measurements do not need to be collected at high frequency or power levels, reducing the cost of purchasing measurement hardware. Scaling in terms of geometry is achieved by combining accurate measurement based non-linear look-up table models of a reference (smaller) transistor with the appropriate passive embedding networks. Experimental results show that the scalable model is successful in predicting the performance of devices up to 5 times larger in gate periphery on two separate Gallium Nitride wafers, one measured at 5 GHz and another at 9 GHz. This approach provides a robust utilization of Behavioural models by providing performance predictions at power levels beyond the limitations of high frequency measurement systems. The geometric scalable Behavioural model was also used in a CAD environment to help create a prototype single cell MMIC amplifier for operation at 5 GHz. Although the targeted performance was not achieved due to mismatch, the non-linear Behavioural model is still able to predict the performance of the actual fabricated circuit. The work in this thesis also introduces the first formulation and approach that enables Behavioural models to be frequency scalable. The experimental results T MINGHAO KOH ABSTRACT IV on HFETs from 2 different Gallium Nitride wafers measured from 2 GHz to 8 GHz (2 octaves), support theoretical analysis that frequency domain Behavioural models defined in the admittance domain have frequency scalable coefficients. Load-pull results show that the model can accurately predict nonlinear behaviour at frequencies that were not used during the model extraction process.
The Effect of Exercise Training on the Detection of Heart Rate and Body Temperature Sensors in Adolescents

The aim of this study is to study the effect of exercise training on heart rate and body temperature sensor detection in adolescents. For the methods of logical analysis, test, and mathematical statistics, this paper takes 60 students aged 13-15 in the experimental middle school as the research subjects to explore the characteristics of heart rate changes of middle school students under different high-intensity intermittent exercise schemes. Then, it analyzes the characteristics of heart rate change in exercise center and heart rate change in high-intensity intermittent exercise. The experimental results show that the high-intensity intermittent exercise of adolescents aged 13-15 presents the stage of rapid recovery and buffer recovery. Whether in the quiet heart rate buffer stage or the rapid heart rate increase stage, as well as the “extreme heart rate maintenance stage” and heart rate recovery stage, the heart rate change point of 15-year-old adolescents is 1-3 seconds later than that of 13-year-old and 14-year-old adolescents. In addition, in the heart rate maintenance stage of 15-year-old adolescents, the heart rate fluctuates greatly. The rapid recovery stage of boys is 1 minute, and the heart rate can reach the quiet heart rate after 4-5 minutes. The rapid recovery stage of girls is 1.5 minutes, and the heart rate can reach the quiet heart rate after 4-5 minutes. The older the age of high-intensity intermittent training of adolescents aged 13-15, the longer the rapid rise stage of heart rate change, and there was no significant change in quiet heart rate buffer stage and body temperature.
Enabling Teaching and Learning Environments in a Contact-Less World

The educational paradigm is constantly evolving; this is largely due to continuous emerging educational tools and technologies. This development has altered the traditional ways of teaching and learning. Present global trends have further increased or forced the adoption of technology in all its ramifications, resulting in a reliance that could have prolonged implications for teaching and learning activities and outcomes. This study discusses the need for enabling teaching and learning environments in the face of swift and continuing technological developments in a post global pandemic era, which has resulted in a contactless world. Metadata and abstracts of reviews on studies were retrieved from science direct database via the search words “enhanced teaching/learning” and “teaching/learning in COVID-19 era”, published between the years 2018 - 2020 and the years 2020–2021 for teaching and learning in a COVID-19 era. This search led to the retrieval of articles on enhanced teaching and learning activities and subsequently articles related to the COVID-19 era. The findings from this study reveal that strategic planning of teaching and learning processes have to be reevaluated.
Mineralogical Association and Geochemistry of Potentially Toxic Elements in Urban Soils Under the Influence of Mining

Polluted soil is an important source of exposure to potentially toxic elements (PTEs) for humans, especially in urban areas. We studied the fate of PTEs in the total ( < 2 mm) and fine ( < 50 µ m) fractions of urban soils in playgrounds, passing areas, and vacant lots of the historic mining village of Minas de Riotinto in SW Spain. The mineralogical and chemical observations included analysis by scanning electron microscopy, electron back-scatter diffraction, X-ray diffraction, chemical analysis of Al, V, Cr, Mn, Co, Ni, Cu, Zn, Rb, Sr, As, Cd, Ba, Tl, and Pb after acid digestion by Inductively Coupled Plasma-Mass Spectrometry and Sb by X-ray fluorescence. The total and fine fractions of natural and mixed (consisting of natural soils and aggregate pavements) urban soils have significantly higher concentrations of sulfide-associated PTEs (Ni, Cu, Zn, As, Sb, and Pb) and Ba in comparison to the aggregate pavements. Most of the natural and mixed urban soils surpass the regulatory levels set by the regional Government for As and Pb to declare a soil as contaminated. This work highlights the mineralogical source of PTEs in the urban soils. Primary geogenic sulfide minerals are prone to oxidation promoting dissolution of PTEs and acid generation in the future. Additionally, for the first time, we have described arsenian plumbojarosite and beudantite in urban soils which are abundant secondary phases under the cir-cumneutral pH conditions, effectively retaining As and Pb. Inhalable small PTE-rich particles ( < 10 μ m) are present in many soils in playgrounds and garden areas potentially posing health risk to residents upon dusting and resuspension in the air.
Building a French-speaking community around UIMA, gathering research, education and industrial partners, mainly in Natural Language Processing and Speech Recognizing domains

﻿We report on the efforts the UN-LINA has made to build a UIMA French-speaking community both in Natural Language Processing and Speech Recognizing domains that would bring together researchers, industrials and educational interests. The intentions of building this community are twofold: to encourage the French-speaking academic and industrial organizations which have not yet adopt a middleware solution to use UIMA as a common development framework and middleware architecture for their research and engineering projects; to improve the collaborative development of common UIMA-based NLP tools and components for processing French. We present the services we set up as well as the resources we distribute freely under open licences to accomplish this objective. Most of them are currently available on the uima-fr.org Web Portal. They consist of: A web portal to discuss and exchange information about UIMA; A bundle of scripts and resources for automatically installing the whole of the Apache UIMA SDK; A bundle of UIMA-based components including some French NLP preprocessing components, a type mapper and a semantic rule-based analyser; A bundle of UIMA tools including an Analysis Engine Apache Maven archetype and an advanced web rest server; Course and training materials.
A class of block alternating splitting implicit iteration methods for double saddle point linear systems

In the framework of a special block alternating splitting implicit (BASI) iteration scheme for generalized saddle point problems, we establish some new iteration methods for solving double saddle point problems by means of a suitable partitioning strategy. Convergence analysis of the corresponding BASI iteration methods indicates that they are convergent unconditionally under certain weak requirements for the related matrix splittings, which are satisfied directly for our specific application to double saddle point problems. Numerical examples for liquid crystal director and time‐harmonic eddy current models are presented to demonstrate the efficiency of the proposed BASI preconditioners to accelerate the GMRES method.
High-efficiency 970-nm multimode pumps

Ultra-reliable very efficient multimode diodes have been developed. 90 micrometer wide aperture chip-on-submount demonstrate 67% peak power conversion efficiency at 25°C and 60% peak power efficiency at 85°C heatsink temperature; while record high thermal limited peak power in excess of 15 W CW is achieved at 15°C. State-of-the-art performance of Chip-on-Submount does not compromise its reliability; over 1,000,000 hours Mean Time Between Failures has been demonstrated. Cooler-less package design ensures thermal resistance of 4.5°C/W from the Chip-on-Submount to external heatsink; coupling efficiency of 95% into 0.15 NA at over 5 W power in 100 μm dia. fiber are routinely obtained. Results of multi-cell accelerated tests of packaged pumps yielded over 10 years of uninterrupted use MTBF at over 5W CW ex-fiber output.
Investigation of thermal and optical performance of a phase change material–filled double-glazing unit

Phase change material applied in the glazing structure can improve its thermal performance, which has effect on its optical performance. A model to determine thermal and optical performance of a phase change material–filled double-glazing unit was developed, and the effect of optical parameters of phase change material was numerically investigated. The results show that the effect of the refractive index of phase change material on temperature time lag, temperature decrement factor, solar transmittance, solar absorptance, and reflectance of a phase change material–filled double-glazing unit is weak when the refractive index of phase change material is lower than 1.95; however, the effect of the extinction coefficient of phase change material is violent. The liquid phase change material with large extinction coefficient is not recommended from the viewpoint of light utilization, but the large extinction coefficient of solid phase change material is accepted from the viewpoint of energy utilization.
Hydrochromic Cspbbr3-Kbr Microcrystals for Flexible Anti-Counterfeiting and Wearable Self-Powered Biomechanical Monitoring

CsPbBr 3 -KBr microcrystals (CPB-K). Interestingly, the as-prepared CPB-K can achieve reversible transition between luminescent and non-luminescent state upon the water removal/exposure owing to the dissolution/recrystallization of luminescent CsPbBr 3 nanocrystals with the help of KBr salts. The coating of polydimethylsiloxane (PDMS) effectively prevents the destruction of CPB-K and maintains its green emission upon moisture. Further, by leveraging the hydrochromic CPB-K and water-resistant CPB-K/PDMS characteristic synergistically realize multiple encryption effects of information, and the hidden information can be clearly identified upon moisture decryption. Because of electrical and dielectric properties of MHPs, a flexible triboelectric nanogenerator (TENG) made from CPB-K/PDMS film as friction layer has been constructed with maximum open-circuit voltage of 43.4 V (loading CPB-K of 20 wt%), about 1.8 times that of the pristine PDMS-based TENG. Additionally, we demonstrate a self-powered wearable sensor based on CPB-K/PDMS TENG for real-time biomechanical monitoring with electrical signals. This work provides an eco-friendly fabrication approach for perovskite-based smart luminescent materials, which further opens up the possibility to expand their diverse applications in wearable electronics.
