Station Blackout Accident and Mitigation Measure for PWR-NPP

The reference plant is a typical three-loop PWR-NPP.The progress of core damage under low pressure and high pressure was studied respectively during a station blackout accident.The results show that the high pressure core melt accident is eliminated when pressurizer surge line creep failure is considered,but core damage is more serious and much hydrogen is generated under low pressure transient.The reason was analyzed and the mitigation measure was suggested when core outlet temperature reached 923 K.Calculation results show that core melt progress is greatly delayed,thus the operators have more time available to recover AC electrical source and take other mitigation measures.
Evaluation of KDP Estimation Algorithm Performance in Rain Using a Known-Truth Framework

Accurate estimation of specific differential phase (KDP) is necessary for rain rate estimation, attenuation correction, and hydrometeor classification algorithms. There are numerous published methods to process polarimetric radar observations of propagation differential phase shift (ΦDP) and estimate KDP, but the corresponding KDP estimate uncertainty is unquantified. This study provides guidance on how commonly used KDP estimation algorithms perform in various environments. We create numerous synthetic (“true”) KDP profiles, integrate over them to obtain “smoothed” ΦDP, and then add noise typical of S-band operational weather radar measurements. Each algorithm is applied to our noisy ΦDP profiles and compared to the true KDP profile such that the errors and uncertainty are quantified. The synthetic KDP profiles are Gaussian in shape, which allows systematic variations in their magnitude and width to determine how each algorithm performs in smooth, slowly changing KDP profiles, as well as steep profiles. Results demonstrate that algorithm performance is dependent on the ΦDP field received. These results are further supported by an error analysis of each algorithm for two more complicated synthetic KDP profiles. Some KDP algorithms allow users to change various tuning parameters; a subset of these tuning parameters is tested to provide guidance on how changing these parameters impacts algorithm performance. We then provide evidence that our known-truth framework provides insight into algorithm performance in observed data through two case studies.
Radiation-Induced Bystander Effect Research: Literature Review

The aim of the present study is to review literature on radiation-induced bystander effect research. The radiation-induced bystander effect concerns a plethora of biological phenomena occurring in nonirradiated cells as a result of signal transmission from irradiated cells. This paper discusses many radiation-induced bystander effect in vitro experiments, e.g., for numerous types of cell lines or tumor cells. The influence of nanomaterials on the radiation-induced bystander effect is analyzed. Moreover, the relationship between the radiation-induced bystander effect and the radiation-induced senescence, inflammatory pathways and endothelial cells is discussed. The authors have tried to explore as many mechanisms accompanying the radiation-induced bystander effect as possible. The in-depth mechanism research on cell proliferation influenced by the bystander effect of radiation will be useful to understand the biological effects of radiation.
EM1‐Signature in the North Fiji Basin: Evidence for Stagnant Slab‐Derived Mantle Upwelling Beneath the Trench‐Distal Back‐Arc Basin

Basaltic volcanism at the mature back‐arc spreading axis in the North Fiji Basin (NFB) exhibits significant geochemical heterogeneity from depleted mid‐ocean ridge basalt (MORB) to enriched MORB compositions. The volatile and Sr‐Nd‐Pb‐He isotope composition of basaltic glasses from the Central Spreading Ridge (CSR) of the NFB suggests that a second enrichment mantle component is present in addition to the previously observed Samoan mantle plume. The hydrous OIB‐like basalts from the northern CSR have a weak enriched mantle 1 (EM1) isotopic signature and negative correlation between Ba/Th and Zr/Hf ratios, similar to rejuvenated Samoan lavas associated with tectonic driven volcanism. The EM1 signature is distinct from shield‐stage Samoan basalts and back‐arc basin basalts from the Lau Basin by high Ba/La ratio and negative correlation between Ba/Th and Ba/Ta ratios, indicating contributions from dehydrated and altered oceanic crust and sediments. Our new geochemical data suggest that focused melting above the mantle transition zone (MTZ) triggered by dehydration of stagnant slab can be a source of the EM1‐like melts containing both elevated 3He/4He ratios (up to 12.52 RA) and altered oceanic slab components. Given the spatial coincidence of the inferred EM1 basalts with the clustered deep earthquakes, our results support the presence of detached oceanic slabs in the MTZ beneath the northern NFB.
Restoring cultural plant communities at sacred water sites

ABSTRACT Water places have been critical to central Australian Indigenous peoples for thousands of years. However, many waterhole communities have been degraded by factors including invasion by large feral herbivores and non-native plants. We document the restoration of two waterholes near Santa Teresa (Ltyentye Apurte), with a focus on culturally significant plants. We described plant communities around waterholes in 2007, before fences were erected to exclude large feral animals, and again in 2018. Plant cover and diversity were higher after fencing and the occurrence of culturally significant plants greatly increased. However, invasive buffel grass was the dominant ground cover after fencing and will require active suppression to allow culturally significant native plants to proliferate. Traditional Owners identified excellent opportunities to achieve restoration through educating young people, with a focus on sharing intergenerational knowledge and engaging local Indigenous rangers in management, enabling them to meet the traditional obligations to care for country.
Robust Hybrid Precoding Design for Securing Millimeter-Wave IoT Networks Under Secrecy Outage Constraint

Hybrid precoding architecture, as a cost-effective approach for millimeter-wave (mmWave) communications, can achieve an excellent tradeoff between spectrum efficiency and hardware implementation complexity. However, the design of a robust hybrid precoding for improving the physical layer security (PLS), which is insensitive to the uncertainty of eavesdropper’s channel state information (CSI), has not been well studied. This article for the first time designs a probabilistically robust hybrid precoding scheme for securing broadcast communications in Internet of Things (IoT) with eavesdropper’s imperfect CSI. Specifically, considering the Gaussian CSI error model, we maximize the minimum secrecy rate of multiple IoT devices (IoDs) by jointly designing analog and digital precoders under the constraints in terms of secrecy outage probability and per IoD’s information rate. The optimization problem is challenging due to the coupling of the analog and digital precoders, and the secrecy outage constraint. To handle these challenges, we first employ a conservative probability inequality to transform the secrecy outage probability constraint into a deterministic one. Then, by employing the penalty dual decomposition (PDD) method, we develop a novel iterative algorithm to convert the resultant nonconvex problem into a sequence of convex problems, which can guarantee the convergence to its Karush–Kuhn–Tucker (KKT) solution. Simulation results show that the proposed algorithm can achieve significant secrecy performance gains compared with the benchmark algorithm.
Villagers perceptions on the existence of hazardous waste treatment facility at Bogor, Indonesia

Indonesian government built a hazardous waste treatment facility near two villages in Bogor, Indonesia. The facility has been operating since 1994, and its activities affect the neighboring villages. There had been two significant conflicts between the village’s community and the company, in 2006 and 2008. The acceptance of the surrounding neighborhood is one of the major risks affecting a company’s lifetime. This study aims to provide the latest perception of the two villages’ community on the facility’s existence. The survey, observation, and in-depth interviews were employed to gather enough information for perception analysis. The perception analysis represents variables: socio-demography, knowledge and information, health issues, social-economy values, and trust. The survey was conducted to 100 respondents, and the data were analyzed as a Likert scale for each variable. The univariate analysis was performed to map the perception, which resulted in “good perception”. The bivariate analysis was performed to explore the socio-demographic variable’s influence on perception. The result showed that there is no significant correlation between age, education level, and occupations with perception. These results can be used as the base information to determine the company’s sustainability strategy.
Statistics of velocity fluctuations in a homogeneous liquid fluidized bed

This work reports an experimental investigation of a liquid-solid fluidized bed involving inertial particles at a large Reynolds number. Owing to optical techniques and index matching, the statistics of the velocity fluctuations of both the particles and the liquid are measured for a wide range of the particle volume fraction αp. The dynamics of the fluctuations suggests that the flow possesses the following three properties: (1) The liquid volume involves a wake region in which vertical fluctuations are negative and an interstitial region where they are positive. (2) The statistics of the horizontal fluctuations are similar to vertical ones, except that they are symmetric. (3) Local instant particle fluctuations are proportional to liquid ones. Assuming these properties are true allows us to derive a model for the probability density functions (PDFs) of the two components of the velocity fluctuations of the two phases. This model involves a single reference PDF that is independent of αp and one weighting parameter for each phase. The weighting parameter of the liquid phase is an affine function of αp, which characterizes the volume of the wakes relative to that of the interstices. That of the particle phase depends on the preferential concentration of the particles, which tend to avoid the wakes at low αp. This model accurately describes the experimental PDFs up to the third-order moment and reproduces all their peculiar features: the skewness of the vertical fluctuations which reverses at a given volume fraction, the presence of exponential tails corresponding to rare intense events, and the symmetry between low and large volume fractions.
Exploring the predictive power of impulsivity measures in predicting self-reported and informant-reported inpatient disruptive behaviors

ABSTRACT Impulsivity is strongly associated with aggression and antisocial conduct. Although self-report measures are a time-efficient means to assess impulsivity, they may be susceptible to socially desirable responding, particularly in forensic psychiatry. The current study aimed to investigate the predictive validity of three measures of impulsivity in predicting self- and informant-reported antisocial behavior: the Barratt Impulsiveness Scale, the Self-Centered Impulsivity scale of the Psychopathic Personality Inventory-Revised and the general Disinhibition factor of the Externalizing Spectrum Inventory. Next, the mediating role of a measure of self-deception, the Virtuous Responding scale, was examined in these associations. Participants (N = 94) were inpatients from addiction care and forensic psychiatry. Two regression analyses were conducted using self-reported antisocial behavior in the first, and informant-reported antisocial behavior in the second analysis as outcome variables. In addition, a mediated regression analysis was conducted, using the Virtuous Responding scale as a mediator. The impulsivity measures showed a substantially lower predictive validity when informant-reported behavior was predicted. The Virtuous Responding scale appeared to be unreliable in the current sample and showed no mediation effect. The results showed insufficient support for the predictive validity of the three measures of impulsivity. Alternative time-efficient assessments for impulsivity are needed, such as informant-based measures.
Ameliorative Effects of Cholestyramine and Oxihumate on Aflatoxicosis in Broiler Chickens

Aflatoxin B1 (AFB1) is widely available mycotoxin that is secreted by certain types of Aspergilli. In this research the ameliorative efficacy of two mycotoxin binders in broilers was evaluated; cholestyramine which was used for the first time in the poultry and oxihumate. A total of 64 one-day-old chicks were divided into four equal groups: birds of group A, B & C were fed on AFB1 contaminated diet at a rate of 2 ppm for 36 days either alone, with cholestyramine at a dose rate of 340µg/kg ration or with oxihumate at a dose rate of 3.5g/kg ration. Group D was kept as control with basal diet of neither toxin nor drug treatment. Morality was highest and the lesions of AFB1 intoxication were pronounced among birds of group A with marked degenerative and necrotic changes in different examined organs. Variable degrees of ameliorative effects of AFB-induced toxic lesions were observed in both treated groups (group B & C) with beneficial effects for cholestyramine. Mild expression of the apoptosis-related marker (p53) was encountered in group B and C relative to AFB1 intoxicated group. Aflatoxin residues were significantly reduced in the bird liver and kidney tissues in the instance of the two antimycotoxin binders. It could be concluded that both cholestyramine and oxihumate have an ameliorative effect for controlling aflatoxicosis with the superiority of cholestyramine in its protective effect. This the first in vivo trail to use cholestyramine as anti-AFB1 agent in poultry
Quantum-Chemical ab initio Study of Side Chain pKa of Linear and Cyclic Lysine Dipeptides

Cyclic dipeptides show interesting biological activities such as antitumor, antiviral and so on. In biological systems, the bioavailability of drugs is determined by several parameters such as pKa values. In this study, we used DFT and thermodynamics cycle to determine pKa value of side chain of lysine in linear and cyclic dipeptides. All considered dipeptides were optimized using B3LYP and RMSD tool was used to compare the optimized structures. The calculated pKa values were compared with the available experimental data. Our results show that pKa of side chain of lysine increases for cyclic dipeptides compared to the linear ones. To justify the reason of increasing of pKa of cyclic dipeptides, we used NBO and AIM analyses. The analyses showed that a hydrogen bond in cyclic lysine dipeptides is responsible for increasing of pKa.
Resident support in China’s new national parks: an extension of the Prism of Sustainability

ABSTRACT Gaps persist in the literature on resident support for tourism in relation to protected area sustainability and resident satisfaction. This study extends Prism of Sustainability research to analyze these linkages, focusing on four communities of China’s newly established Shennongjia National Park. An ‘interpretation’ mixed methods research design focuses primarily on SEM and bootstrap analyses of surveys (n = 403) from 2018–19 fieldwork, augmented by qualitative analysis of semi-structured interviews (n = 151) conducted during that time. Results suggest satisfaction fully mediates the economic dimension-to-support relationship, but partially suppresses the institutional dimension-to-support relationship. These findings hold implications for rural and protected area tourism more broadly, underscoring with empirical data the importance of considering resident satisfaction as a possible mediator between support and certain sustainability dimensions.
Analysis of the phytochemical content and anti-microbial activity of Jatropha gossypifolia L.

The importance of plant is well known. Life and its growth cannot be imagined without plants. They not only produce food for survival but also create healthy environment and eco-friendly atmosphere to live. Jatropha gossypifolia Linn. well known plant of family Euphorbiaceae is used as a therapeutic agent. The leaf decoction of this plant is used for bathing wounds, sores, sprains, rash and bewitchment. In the present investigation the leaves of J. gossypifolia L. were screened for antibacterial activity by extracting them successively in various solvents such as Petroleum ether, Benzene, Chloroform, Acetone, Alcohol and Water. Crude powder of leaves was screened for the presence of chemically active compounds by standard methods and for antibacterial activity by zone of inhibition. The results revealed the presence of saponin, tannin, flavonoid, reducing sugars, cardiac glycosides, terpenoids, triterpenoids, steroids, xanthoprotein, starch. The medicinal values of this plant could be attributed to the presence of one or more of the detected metabolites.
Theoretical and experimental investigation of two-layer circular patch antenna excited by a coaxial probe

Abstract In this article, we present two efficient closed-form models to examine thoroughly the dependence of resonant frequency, quality factor, probe reactance, input impedance, bandwidth, and gain on parameters such as patch radius, probe location, substrate electrical parameters, and air gap of a coax probe-fed circular patch antenna. The implementation of these models is very easy and the computation cost is very low. The proposed models show excellent agreements with experimental and simulation results. We have also investigated experimentally the gain patterns of a suspended substrate circular patch antenna.
The impact of time‐varying sea surface temperature on UK regional atmosphere forecasts

A new approach to improve the ocean surface boundary condition used in regional numerical weather prediction is proposed. Typically, regional atmosphere forecast systems assume a fixed sea surface temperature during a simulation. The study assesses the use of ocean temperature from an operational regional ocean model as an evolving lower boundary in a kilometre‐scale regional atmosphere configuration centred on the UK. Simulations of a winter and two five day duration summer case studies associated with anomalously warm temperatures are considered. The largest impact is found in summer, when a growing cold bias in mean temperature over land compared with observations is apparent when using a fixed global‐scale analysis lower boundary condition. The mean error is improved by 0.1 K when using a fixed temperature boundary condition from a kilometre‐scale regional ocean model initial condition. When using hourly surface temperature data from the same regional ocean model, the error is improved by 0.5 K for this case. Prediction of daytime maximum air temperature is also improved during the summer heat wave cases. A winter case study shows marginal improvement over the ocean and negligible changes over land. These results are confirmed in longer duration experiments using an hourly cycling regional forecast system with data assimilation for summer and winter periods. A systematic and statistically significant improvement of near‐surface temperature verification relative to the observations over land is demonstrated for both summer and winter using the new approach. This study supports future operational implementation of a time‐varying lower boundary for regional numerical weather prediction.
Perception of Organizational Politics and its Impact on Job Performance

This paper aims to examine the understanding of organizational politics and its impact on the job performance of Nepal's civil service employees. The research design adopted in this study consists of a descriptive and causal-comparative research design. Based on a multi-stage random sampling, 250 civil servants in five ministries of the Nepal Government were selected as sample. The response rate was 76.40 percent. The findings of this research indicate that strong organizational politics exist at government offices. Mainly, over politics exist in the case of pay and promotion policies. Likewise, going along to get ahead and general political behavior are also common at these offices. The job performance level, however, was found at an average level. The inferential results indicate that there is a significant negative impact of organizational politics (in terms of going along to get ahead, pay and promotion policies, and general political behavior) on the job performance of employees. Therefore, leaders and administrators of ministries and other government offices need to keep an eye open in such realities and try to reduce unnecessary politics at workplaces so that the civil servants can focus on delivering effective services to the general public.
Polish adaptation of emotional Stroop test in assessment of pedophilia - a pilot study.

OBJECTIVES A pilot study was conducted in order to construct a Polish adaptation of emotional Stroop test in assessment of pedophilia. METHODS The study consisted of two stages. The first stage involved creating test material by ranking words in adequate lists by competent experts. The second stage consisted of empirical verification of the principle of emotional Stroop test in a non-clinical population. RESULTS Based on the assessment of five competent experts, words were ordered from the most to the least sexually arousing (Kendall's W from 0.368 to 0.693). Six ranked lists were obtained, and the competent experts were subsequently asked to assess whether these lists were suitable for the study (Lawshe's Content Validity Ratio from 0.6 to 1.0). Two categories of words were merged. Five ranked lists were obtained, and the competent experts were subsequently asked again to assess whether these lists were suitable for the study (Lawshe's Content Validity Ratio 1.0). The created lists of words were approved by allcompetent experts. Based on the experimental study conducted on a non-clinical population, it was shown that, in accordance with the principle of the test, the mean response time for sexually related words was longer that for neutral words. The mean response time for children-related words did not differ significantly from response time for neutral words. CONCLUSIONS Based on the study with competent experts and conducted experiments, an initial Polish adaptation of the emotional Stroop test for diagnosis of pedophilia has been created. Further studies with persons with pedophilia are needed to implement the test in clinical setting.
