Radionuclide Chain Transport Through Heterogeneous Media

A one-dimensional radionuclide chain transport model is developed, taking into account sorption, longitudinal dispersion, and arbitrary repository concentrations. For piecewise constant geologic parameters, a semianalytic solution can be written down, when, at the layer boundaries, mass conservation is considered rigorously and flux conservation to a good approximation. The solution consists of a superposition of terms that are easily interpreted and is invariant under layer permutation and parameter scaling. A corresponding computer code RANCH has been developed. The /sup 245/Cm chain has been investigated for a broad variation of parameters of a three-layer geology. For very small retention factors only, /sup 245/Cm and /sup 241/Am can survive migration in the geologic medium, while /sup 237/Np is reduced by at most three orders of magnitude.
Playful activity remained constant while electronics use increased in children during social distancing amidst the COVID-19 outbreak: A Poá’s pilot study

PUBLICATION DATA Received 19 01 2021 Accepted 25 02 2021 Published 01 03 2021 BACKGROUND: The disease caused by the novel coronavirus (COVID-19) has produced one of the most dramatic health crises, impacting humans’ daily lives worldwide. Social distancing and lockdown measures have limited everyone’s daily activities and have likely also affected children’s physical activity. AIM: To investigate physical activity and electronics use during COVID-19 social distancing in children from the city of Poá, São Paulo. METHOD: Data from 28 children (10 males, 18 females) were obtained on two occasions: pre-pandemic (October 2019) and during the pandemic (May 2020). To further examine possible changes in physical activity, data from another sample of 40 children (20 males, 20 females) were obtained during the pandemic (May 2020). From both cohorts, anthropometric information and play, television, electronics, and sleep time expenditures were obtained using a questionnaire. RESULTS: Results from the first cohort (28 children) showed similar time spent engaged in playful activities and sleeping before and during the pandemic. Although hours spent watching television remained constant, a dramatic increase in the overall electronics time expenditure was observed (from 3.4 to 5.8 hours/day) during the pandemic period. A comparison of the results for the two cohorts confirmed these findings: there were no between-group differences in the data obtained during the pandemic period. CONCLUSION: Although the children maintained their play time while social distancing, an increase in the time spent using electronic devices was observed, possibly due to the characteristics of the social distancing implemented in Brazil, as well as the characteristics of the children’s neighborhood.
ISOLATION, CHARACTERIZATION, AND APPLICATION OF BACTERIOPHAGES AGAINST SEVERAL FOOD SPOILAGE BACTERIA: Bacillus subtilis, Bacillus cereus, AND Shewanella Putrefaciens

Introduction: Bacteriophages can be the natural alternative method to prevent food spoilage caused by bacteria. This research was conducted to isolate bacteriophages from a soil sample, retail food, and wastewater from fish and then the bacteriophages will be characterized for their activity against several food spoilage bacteria, such as Bacillus cereus, Bacillus subtilis, and Shewanella putrefaciens and will be further investigated for application as food preservation. Experimental: B. cereus (Atma Jaya culture collection), B. subtilis ATCC 6633, and S. putrefaciens ATCC 8071 were used for bacteriophage isolation. Food samples (rice, pasta, tofu, tempeh), soil samples (black soil and laterite), and wastewater sample of freshwater fish and seawater fish were used in this research. The overall process consists of eight steps: inoculum preparation, sample collection, bacteriophage isolation, purification and enrichment, titer determination, host range determination, the efficiency of plating (EOP), and bacteriophage application. Results: A total of four bacteriophages were isolated with B. cereus, B. subtilis, and S. putrefaciens as host bacteria. Bacteriophage titers observed around 109 PFU mL-1. Bacteriophages that isolated with B. cereus and B. subtilis as host bacteria tend to have high EOP with the same species bacteria. All the Bacillus phages (S1-BC, S2-BC, and S1-BS) can reduce the Bacillus species bacteria concentration for more than 90%. Conclusion: Refers to their activity, the isolated bacteriophages in this study might have a great prospect to be used as food biocontrol and also can be further tested to make a phage cocktail.
Antibiotic susceptibility pattern and plasmid profiles of nasal staphylococci from apparently healthy Nigerians

A total of 480 nasal samples from apparently healthy Nigerian students were collected aseptically and analyzed bacteriologically. Staphylococci were recovered from 432 (90%) of the subjects, constituting 288 (66.7%) and 144 (33.3%) of S. aureus and S. epidermidis respectively. The in-vitro antibiotic susceptibility testing using the disc diffusion technique showed high multiple resistance to the most commonly used antibiotics by Staphylococcus aureus such as penicillin (98.6%), ampicillin (97.2%), tetracycline (95.8%) and streptomycin (84.7%), but less resistance to erythromycin (9.7%), rocephin (8.3%), peflacin (4.2%) respectively. The S. epidermis showed less resistance to all the antibiotics tested. Sixty percent of S. aureus harbored plasmids which molecular sizes ranged from 0.1 to 12.0 kilobases. The high prevalence of multiple antibiotic resistance appear to be plasmid mediated as plasmid profile analysis showed that about 90% of S. aureus harbored plasmids
Refugee Mobilities and Institutional Changes: Local Housing Policies and Segregation Processes in Greek Cities

Many studies have explored the dynamics of immigrant and refugee settlement at the local level, highlighting that it is actually a two-way process: On the one hand, the local socio-political context specifies the conditions for refugee inclusion, and on the other, migrant mobility leads to the transformation of localities in various ways. In Greek cities, the social practices of local actors have played an important role in the implementation of the immigration policy, where refugees were perceived as a threat to personal and community security. Yet, new forms of social mobilisation and solidarity by individual citizens and community initiatives have worked to alter these attitudes, mitigating tensions and obstacles in refugee acceptance. The article draws on the Greek experience to explore the role and importance of the local socio-political texture in refugee inclusion, shedding light on how it gave rise to various local initiatives that inform refugee allocation as well as urban transformation and institutional change. In methodological terms, the article considers three neighbouring Greek cities as case studies to identify the different institutional and policy responses to refugee accommodation, giving rise to different paths and forms of social inclusion. The study reveals the complexity and context of the social-spatial diversity that refugees face but also the transformation dynamics of local states and civil society.The paper draws on the Greek experience to explore the role and importance of social infrastructure in refugee integration, shedding light on how these qualities, materialized in local initiatives for refugee integration to influence urban transformation and institutional change. In methodological terms, the paper employs three small and medium-size Greek cities as case studies to identify the different institutional and policy responses to refugee accommodation followed, giving rise to different paths and forms of social inclusion and urban transformation. The study reveals the complexity and the contextuality of the social spatial diversity that refugees face but also the transformation of local states and civil society.
ExLing 2020

This study investigates how statistical regularity concerning the distribution of lexical tones and consonantal onsets in Mandarin, formulated as the “tone-consonant cooccurrence probability (TCCP)” here, influences results of wordlikeness judgment task. Native speakers were asked to rate the wordlikeness of monosyllabic real words and pseudowords with existing segmental combinations. Overall, real words with high probability were considered more wordlike than those with low probability. On the other hand, the probability effect was not significant on the well-formedness ratings of the pseudowords. These findings suggest that speakers are sensitive to the toneconsonant co-occurrence patterns, which follow gradual tendencies rather than an “allor-nothing” manner, but such sensitivity is probably limited to existing forms and cannot be extended to hypothetical ones.
A PLS multigroup analysis of the role of businesswomen in the tourism sector in Andalusia

The objective of this study is to determine the factors that influence “business performance” or the “role of entrepreneurs”, as well as to analyse whether gender functions as a moderating variable, based on a survey conducted on a sample of 127 companies. Most of the literature in the tourism sector only considers hotel accommodation; thus, it is still limited in the case of nonhotel accommodation. Our research fills this gap by focusing on both types of establishments. An explanatory and confirmatory model has been carried out based on a PLS-SEM approach, taking the factors that determine business performance into account. Moreover, a MICOM and a multi-group analysis have been undertaken in order to check whether gender acts as a moderator. Our findings reveal that there are no significant differences between tourist accommodation companies run by women and men in Andalusia; hence, gender is not a moderating variable regarding business performance. Furthermore, as full measurement invariance has been established, a comparison between groups emphasises that the influence of the environment, and the resources and capabilities of the entrepreneur, are factors that affect women more than men, and the number of employees, work experience, and the occupancy rate are more important for businesswomen, whereas the distance to the nearest airport, check-in, and the occupancy rate are more important for businessmen. This empirical study has practical implications for hospitality industry professionals and concerned authorities which are responsible for designing strategies and policies related to this sector in Andalusia.
Cauda Equina Syndrome Caused by a Sacral Insufficiency Fracture in the Lower Part of Zones 2 and 3: A Case Report

nied by cauda equina syndrome (CES). We report a case of CES caused by SIF in the lower part of zones 2 and 3, which is not a typical location. A postmenopausal woman often sat on a chair for long periods, and pain in the coccyx and perianal area occurred. After 4 years, during which time the pain worsened and she developed urinary and fecal incontinence, magnetic resonance imaging showed a SIF involving the S3-S5 vertebrae. Prolonged latency of the bulbocavernosus reflex was confirmed through an electrodiagnostic study, and detrusor underactivity was confirmed through a urodynamic study, leading to a CES diagnosis. Unlike typical cases of osteoporotic SIF, the fracture occurred at an atypical location. We believe that long periods of sitting caused a different weight-bearing pattern of the sacrum from that found in typical cases.
A cross-sectional study on the physical activity of selected elderly diabetics

Regular exercise may prevent or delay the development of Type 2 Diabetes Mellitus (T2DM). In addition to moderate- to vigorous-intensity exercise, daily physical activity is also important for the prevention and management of T2D. Elderly diabetics (50-70 years) were selected from the PSG Hospitals - a multi-specialty hospital. A Diabetes Self-Management Questionnaire (DSMQ) was developed to be locally relevant. The validity and reliability was checked before administration of the questionnaire. Data on glycemic control, energy expenditure, and physical activity (MET) were recorded. Physical activity from age 50-60 & 60-70 years were similar as indicated by the 24hr physical activity pattern and MET values. We observed a progression of the metabolic disorder with age as shown by HbA1c values Physical activity and exercise recommendations, therefore, should be tailored to meet the specific needs of each individual.
Efficacy of Sunflower Oil in Modulating Rumen Functions and Reducing Enteric Methane Production in Buffalo (Bubalus bubalis)

Methane (CH4) is produced in digestive tract of ruminant l ivestock by fermentation of feeds with anaerobic microorganisms (bacteria, protozoa, fungus, archaea) and emitted to the environment via burping mainly. Since CH4 has no nutritional value to the animals, its production represents a loss of 2-12 % dietary gross energy intake (Johnson and Johnson, 1995). Methane production not only reduces the efficiency of feed energy utilization but also contributes to global warming. Ruminant animals contribute about 18% of the global anthropogenic greenhouse (GHG) gas emissions mostly due to anaerobic enteric fermentation of feeds. About 37-44 % of global methane emissions are contributed by ruminant livestock and are a major source of methane production in the agriculture sector (IPCC, 2007). Therefore, reducing enteric methane production by dietary modulation of livestock feeding is one of the major strategies not only in view of clean animal production, but also increasing the utilization efficiency of feed energy in productive purpose. Vegetable oils, a source of poly-unsaturated fatty acids, have the potential to reduce enteric methane production.

Investigating the Association between Personality Traits and Mental Health with Accident Proneness in Iranian Male Workers of Chemical Industries

The purpose of this study was to investigate the association between five personality traits of Zuckerman theory and the General Mental Health Index between two groups of individuals in terms of accident proneness score and to present a predictive model of accident proneness trait in the studied population. This cross-sectional study was conducted on 270 Iranian male workers of chemical industries having work experience of at least one year and a maximum age of 45 years voluntarily participated in the research. The baseline data and background information of all participants were collected and they were asked to fill out the GHQ-28 questionnaire, Zuckerman-Kuhlman personality questionnaire, and TAS subscale of the Zuckerman Sensation-Seeking Scale-V (SSS-V). The results showed that work experience (p=0.002), marital status (p=0.041), social dysfunction (p=0.037), severe depression (p=0.023), and aggression hostility (p=0.020) were significantly varied between the two groups of accident-prone and non-accidentprone. Also, using the variables investigated by the binary logistic regression model, the attribute of having or not having accident proneness was predicted at R Square of 0.416. It was found that personality traits of Aggression Hostility and Psychological Symptom of Social Dysfunction and Severe Depression have associated with accident proneness in the population under study.
SUSTAINABLE MANAGEMENT STRATEGY FOR MANGROVE FOREST OF PELITA JAYA BAY AND KOTANIA BAY, WESTERN SERAM, INDONESIA

The coastal area of Pelita Jaya Bay and Kotania Bay is a semi enclose estuary area having three typical most productive ecosystems i.e. mangrove, seagrasses, and coral reefs with the mangrove ecosystem being the dominant one making this area a productive in fish resources. Local community neighboring this area used mangrove ecosystem for many different purposes, some of it threatening the sustainability oh the ecosystem. The objective of this study was to analyze mangrove forest sustainability and to propose sustainable mangrove forest management. Rapfish analysis was used to analyze mangrove sustainability status. A sustainable management strategy was developed using a conceptual model framework combined with the DPSIR approach. The two most sensitive attributes affecting mangrove sustainability from Leverage analysis were used as the State component from DPSIR. The result shows that overall mangrove forest sustainability was 60% and was considered fair sustain with the ecological dimension having the highest sustainable scale (85.35%) and considered sustain, whilst institutional dimension having the lowest sustainable scale (29.10%) and considered unsustain. The sustainable mangrove management strategy proposed consists of workshops, training, vocational education concerning EAM, as well as replanting degraded mangrove forests, monitoring, surveying, and controlling. The management strategy should be conducted based on a co-management approach.
Exploring the herbicidal potential of some weed species by using two distinct extraction methods

Weed management is extremely important for sustainable crop production in all cropping systems. The use of weedicides is one of the best approaches to keep the weeds under check but the repeated use of few selective herbicides is giving rise to problem of herbicide resistant weeds and environmental pollution. Therefore, it is imperative to identify plant species having herbicidal potential so that their bio-extracts may be used as more safe and effective novel weed management means. The present study was conducted to explore the plant growth inhibitory activity of aqueous and N-hexane extracts of Adiantum capillus-veneris, Parthenium hysterophorus and Sisymbrium orientale. A completely randomized design with factorial arrangements was used for the experiment with four replications. Aqueous and N-hexane extract of Sisymbrium orientale completely inhibited lettuce (Lactuca sativa L.) seed germination while maximum mean germination time, time taken to 50% germination, lowest germination index and seedling dry weight was observed when N-hexane extract of Parthenium hysterophorus was applied. Generally, N-hexane extracts showed more phytotoxicity than aqueous extracts. This study demonstrates that S. orientale extract have comparatively more active substances with ability to suppress germination and growth of plants which could be exploited as prospective source of bio-herbicides.
Analyzing the Impact of Fiscal Policy (Income Tax) on Income Distribution in Iran by Autoregressive Distributed Lag (ARDL) Approach

Economic justice and equitable distribution of income, along with important issues such as economic growth and development, the reduction of inflation and unemployment, have always been of concern to economists. Fair distribution of income and reduction of income inequality in society, and the identification of factors affecting income inequality to make the right policy are necessary and obvious. The purpose of this paper is to examine the impact of income tax on income distribution in Iran. In this regard, Autoregressive Distributed Lag (ARDL) approach has been used to investigate the existence of a long-run relationship between variables and to estimate the coefficients related to long-run and error correction models for income inequality from 1978 to 2012. The results indicate a long-run relationship among the variables and show that an increase in income tax revenues leads to a reduction in income inequality.
A Dynamic Analysis on the Validity of the Phillips Curve for Turkey

The connection between inflation and unemployment is one of the most discussed issues of macroeconomy. This study investigates the Phillips curve, which expresses the trade-off between inflation and unemployment, using Bound test approach, ARDL method and Kalman Filter for the period between 1996 and 2016 for Turkish economy. In the empirical analysis, co-integration relationship between inflation and unemployment has been determined by Bound test. ARDL model results suggest that unemployment rate is statistically significant and negatively affects inflation rate in the long run. Although the short-run coefficient obtained from ARDL model is not statistically significant, the trade-off has been stated between inflation and unemployment in the long run. Kalman Filter model is employed in order to analyze dynamic relationship between inflation and unemployment. The results show that the effect of unemployment on inflation has significantly increased after the implementation of inflation targeting regime in 2002.
Evolution of Algorithm Portfolio Methods for Combinatorial Search and Optimization Strategies

The last decades have witnessed tremendous growth in the performance of solvers dealing with NP-hard problem instances. Commonly, powerful solvers outperform the other candidates for the majority of cases but obtain poor results for particular sub-domains. For this reason, Algorithm Portfolio approaches have been developed, allowing to exploit a set of solvers with complementary strengths, instead of running a single best one for all instances. Recent successful implementations combine these approaches with automatic Algorithm Conﬁguration methods, which consider a single parameterized solver and identify the best putative values of its hyper-parameters for the analyzed instances distribution. This paper aims to illustrate the development of the principal approaches that leverage machine learning to accelerate the solution search of modern solvers. Furthermore, it presents the basic notions necessary to understand the process that enabled these techniques to achieve their amazing results with some of the many performing implementations for SAT, Answer Set Programming , and Constraint Programming .
Multi-Aspect Sentiment Analysis Hotel Review Using RF, SVM, and Naïve Bayes based Hybrid Classifier

In the hotel tourism sector, of course, it cannot be separated from the role of social media because tourists tend to share experiences about services and products offered by a hotel, such as adding pictures, reviews, and ratings which will be helpful as references for other tourists, for example on the media online TripAdvisor. However, tourists' many experiences regarding a hotel make some people feel confused in determining the right hotel to visit. Therefore, in this study, an aspect-based analysis of reviews on hotels is carried out, which will make it easier for tourists to determine the right hotel based on the best category aspects. The dataset used is the TripAdvisor Hotel Reviews dataset which is already on the Kaggle website. And has five aspects, namely Room, Location, Cleanliness, Registration, and Service. A review analysis was carried out into positive and negative categories using the Random Forest, Support Vector Machine, and Naive Bayes Hybrid Classifier-based methods to solve this problem. In this study the Hybrid Classifier method gets better accuracy than the classification using one algorithm on multi-aspect data, namely the Hybrid Classifier gets an average accuracy of 84%, Naive Bayes gets an average accuracy of 82.4%, Random Forest gets an average accuracy of 82.2%, and Support Vector Machine get an average accuracy of 81%.
