ON FARADAY INSTABILITY IN MAGNETIC LIQUIDS: INCE-ERDELYI APPROACH APPLIED TO THE HILL EQUATION DESCRIBING OSCILLATIONS OF A FERROFLUID FREE SURFACE

Abstract When an isothermal ferrofluid is submitted to an oscillating magnetic field, the initially motionless liquid free surface can start to oscillate. This physical phenomenon is similar to the Faraday instability for usual Newtonian liquids subjected to a mechanical oscillation. In the present paper, we consider the magnetic field as a sum of a constant part and a time periodic part. Two different cases for the constant part of the field, being vertical in the first one or horizontal in the second one are studied. Assuming both ferrofluid magnetization and magnetic field to be collinear, we develop the linear stability analysis of the motionless reference state taking into account the Kelvin magnetic forces. The Laplace law describing the free surface deformation reduces to Hill’s equation, which is studied using the classical method of Ince and Erdelyi. Inside this framework, we obtain the transition conditions leading to the free surface oscillations.
The Prevalence of Postpartum Depression and Its Association with Food Insecurity among Mothers Referring to Community Health Centers

Objective: Postpartum depression (PPD) is a condition which may compromise both maternal and neonatal health. The present study was conducted to determine the prevalence of PPD and its association with demographic, socioeconomic, obstetric, and household food security status. Method : This cross sectional study was conducted in community health centers in west of Tehran. A total of 325 women were selected by stratified sampling method from community health centers. A sociodemographic questionnaire, USDA 18-item questionnaire, and Edinburgh Postnatal Depression Scale (EPDS) questionnaire were used for data collection. Data were analyzed using both descriptive and analytic analyses, such as chi-squared test and logistic regression in SPSS 22. Results: The prevalence of PPD and food insecurity among the studied population was 35.4% and 34.2%, respectively. The results of this study revealed a significant association among PPD and food insecurity (OR = 6.690, CI = 3.118-14.353, p<0.001), the levels of economic satisfaction (OR = 3.419, CI = 1.241-9.420, P = 0.017), pregnancy loss (OR = 1.899, CI = 1.006-3.582, p = 0.048), and pregnancy complications (OR = 1.853, CI = 1.083-3.170, P = 0.024). Conclusion: Based on the results of this study, household food insecurity may predispose mothers to PPD. Moreover, it was observed that mothers with poor economic satisfaction were more likely to be depressed. Histories of pregnancy loss and pregnancy complications were other risk factors for PPD.
Deriving Mixed-Phase Cloud Properties from Doppler Radar Spectra

Abstract In certain circumstances, millimeter-wavelength Doppler radar velocity spectra can be used to estimate the microphysical composition of both phases of mixed-phase clouds. This distinction is possible when the cloud properties are such that they produce a bimodal Doppler velocity spectrum. Under these conditions, the Doppler spectrum moments of the distinct liquid and ice spectral modes may be computed independently and used to quantitatively derive properties of the liquid droplet and ice particle size distributions. Additionally, the cloud liquid spectral mode, which is a tracer for clear-air motions, can be used to estimate the vertical air motion and to correct estimates of ice particle fall speeds. A mixed-phase cloud case study from the NASA Cirrus Regional Study of Tropical Anvils and Cloud Layers- Florida Area Cirrus Experiment (CRYSTAL-FACE) is used to illustrate this new retrieval approach. The case of interest occurred on 29 July 2002 when a supercooled liquid cloud layer based at 5 km .
Impacts of a comprehensive public engagement training and support program on scientists’ outreach attitudes and practices

ABSTRACT Scientists are increasingly being called upon to play a more prominent role in the interface of science and society by contributing to science literacy in ways that support two-way exchanges with the public. However, many remain reluctant to participate in public engagement activities in part because they feel they lack relevant skills and experience. We surveyed scientists trained on engagement through a nationwide program called Portal to the Public and examined how participation in the program may have influenced their self-efficacy, commitment and attitudes about outreach, and perceived benefits from conducting outreach based on two-way exchange with lay audiences. Participating scientists who responded to the survey reported being deeply involved in and highly committed to hands-on interactive public outreach, felt their engagement skills had improved, and even viewed benefits of their engagement training that extended into university teaching and career development. Our findings suggest a comprehensive engagement training model, which incorporates learning theory, helps scientists build their own outreach strategies, provides opportunities to practice, and offers easy access to audiences, can have a sustained impact on disposition, perceived skills, and type of outreach conducted by scientists interested in deeper engagement with the public.
Dueling in the penalty box: evidence-based recommendations on how shooters and goalkeepers can win penalty shootouts in soccer

In soccer, penalty kicks can decide the outcome of a match and in recent years, much effort has been invested in trying to identify the factors that influence successful performance. This overview presents some of the most important findings in order to compile a reliable set of facts that can improve the probability of success for either penalty takers or goalkeepers. Particular attention is paid to various strategic aspects in the shooter–goalkeeper interaction as previous research suggests that the chances of success on both sides may be greatly enhanced by applying findings from research in sport psychology. The article ends with a checklist that goalkeepers and penalty takers may use to improve their chances of success alongside recommendations to continue and intensify the efforts to carry out ecologically valid experiments in future research.
On measurements of stage acoustic parameters : time interval limits and various source-receiver distances

The most widely recognized objective stage acoustic parameters are the Early Support (STearly) and Late Support (STlate ). In these parameters the early and late reflected sound energy is measured within a certain time interval. Different time interval limits have been proposed for the stage acoustic parameters but there is no agreement on the preferable limits. There is a growing interest to measure stage acoustic parameters at various source to receiver distances. In this paper the influence of perceptual and architectural parameters, synchronicity, source to receiver relationship and the measurement system on stage acoustic parameters is discussed. Based on existing and new insights an optimization and extension of the ST parameters is proposed such that they can be measured at any distance between source and receiver using the most appropriate time interval limits. Theoretical assumptions were checked and confirmed based on systematic analyses of measured results for different concert hall stages with various conditions and various source to receiver distances.

Haematological alterations of Leporinus macrocephalus (Osteichtyes: Anostomidae) naturally infected by Goezia leporini (Nematoda: Anisakidae) in fish pond

The effect of Goezia leporini Martins & Yoshitoshi, 2003 (Nematoda: Anisakidae) infection on the haematological characteristics of cultivated Leporinus macrocephalus (Osteichthyes:Anostomidae) was studied. Paleness of gills, kidneys, liver and heart, black spots on the kidney and accumulation of fluid in the visceral cavity, stomach and intestines were observed. Gall bladder content had pale and translucent aspect. Strong and slight positive correlations between number of nematodes and fish weight were estimated within the 0-100g and 100-200g fish weight group, respectively. Blood smears from infected fish showed variation in erythrocyte size (anisocytosis) and shape (poikilocytosis), and also dividing erythrocytes. No significant alteration (P>0.05) was shown as to erythrocyte, leukocyte count, haemoglobin concentration and thrombocyte and monocyte percentage. Parasite infection provoked significant reduction (P<0.05) in hematocrit, mean corpuscular volume, mean corpuscular haemoglobin concentration and lymphocyte percentage. On the other hand, significant increase (P<0.05) in neutrophil and eosinophil percentage in circulating blood of infected fish was observed. This is the first report regarding haematology of nematode infected freshwater cultivated fish in Brazil.
Risks for human health related to the presence of pyrrolizidine alkaloids in honey, tea, herbal infusions and food supplements

Abstract EFSA was asked by the European Commission to deliver a scientific opinion on the risks for human health related to the presence of pyrrolizidine alkaloids (PAs) in honey, tea, herbal infusions and food supplements and to identify the PAs of relevance in the aforementioned food commodities and in other feed and food. PAs are a large group of toxins produced by different plant species. In 2011, the EFSA Panel on Contaminants in the Food Chain (CONTAM Panel) assessed the risks related to the presence of PAs in food and feed. Based on occurrence data limited to honey, the CONTAM Panel concluded that there was a possible health concern for those toddlers and children who are high consumers of honey. A new exposure assessment including new occurrence data was published by EFSA in 2016 and was used to update the risk characterisation. The CONTAM Panel established a new Reference Point of 237 μg/kg body weight per day to assess the carcinogenic risks of PAs, and concluded that there is a possible concern for human health related to the exposure to PAs, in particular for frequent and high consumers of tea and herbal infusions. The Panel noted that consumption of food supplements based on PA‐producing plants could result in exposure levels too close (i.e. less than 100 times lower) to the range of doses known to cause severe acute/short term toxicity. From the analysis of the available occurrence data, the CONTAM Panel identified a list of 17 PAs of relevance for monitoring in food and feed. The Panel recommended continuing the efforts to monitor the presence of PAs in food and feed, including the development of more sensitive and specific analytical methods. A recommendation was also issued on the generation of data to identify the toxic and carcinogenic potency of the PAs commonly found in food.
Explaining anomalies with Sapling Random Forests

The main objective of anomaly or outlier detection algorithms is ﬁnding samples deviating from the majority. Although a vast number of algorithms designed for this already exist, almost none of them explain, why a particular sample was labelled as an anomaly (outlier). To address this issue, we propose an algorithm called Explainer, which returns the explanation of sample’s diﬀerentness in disjunctive normal form (DNF), which is easy to understand by humans. Since Explainer treats anomaly detection algorithms as black-boxes, it can be applied in many domains to simplify investigation of anomalies. The core of Explainer is a set of speciﬁcally trained trees, which we call sapling random forests. Since their training is fast and memory eﬃcient, the whole algorithm is lightweight and applicable to large databases, data-streams, and real-time problems. The correctness of Explainer is demonstrated on a wide range of synthetic and real world datasets.
Tax evasion with a conscience

How do moral concerns affect tax compliance and the need for audits? We propose answers by exploring an inspection game, modified to incorporate belief-dependent taxpayer guilt, unawareness, and third-party audience effects. Novel conclusions are drawn regarding whose behavior is affected by moral concerns (it's the authority's more than the citizen's) and regarding policy, in particular fines vs. jail, the role of information campaigns, and the use of a principle of public access whereby tax returns are made public information.
Comparison of Physicochemical and Sensory Properties of Freeze-concentrated Milk with Evaporated Milk during Storage

This study was carried out to compare the changes of nutrients, sensory and chemical properties of freeze-concentrated and evaporated milks during storage. For pasteurization, the freeze-concentrated milk containing 27% of total solid was treated with 150 rpm ozone for 5 min, and 99% of microflora was eliminated. Also, the activities of protease and lipase decreased 93.31% and 96.15%, respectively, and phosphatase showed negative activity. Total bacteria count was maintained below 2.0×10 4 CFU/ml. During storage, TBA absorbance was lower in freeze-concentrated milk than that in the evaporated milk. The production of short-chain free fatty acids and free amino acids increased proportionally to the storage period in both samples. While the short-chain free fatty acid production was lower in the freeze-concentrated milk compared with that in the evaporated milk, the production of individual free amino acid was similar in both samples. In sensory evaluation, cooked flavor and color were much lower in the freeze-concentrated milk than that in the evaporated milk. Overall acceptability score was higher in the freeze-concentrated than the evaporated milk. Based on above results, ozone treatment for the freeze-concentrated milk pasteurization was positive at the elimination of microflora and enzyme inactivation. During storage, the freeze-concentrated sample minimized the change of color and TBA absorbance, the production of short-chain free fatty acid and vitamins than the evaporated milk. Therefore, the freeze-concentrated milk process in the present study resulted in the positive effect in minimizing nutrient loss and keeping quality of milk during storage.
Social vulnerability of rural households to flood hazards in western mountainous regions of Henan province, China

Abstract. Evaluating social vulnerability is a crucial issue in risk and disaster management. In this study, a household social vulnerability index (HSVI) to flood hazards was developed and used to assess the social vulnerability of rural households in western mountainous regions of Henan province, China. Eight key indicators were identified using existing literature and discussions with experts from multiple disciplines and local farmers, and their weights were determined using principle component analysis (PCA) and an expert scoring method. The results showed that (1) the ratio of perennial work in other places, hazard-related training and illiteracy ratio (15+) were the most dominant factors of social vulnerability. (2) The numbers of high, moderate and low vulnerability households were 14, 64 and 16, respectively, which accounted for 14.9, 68.1 and 17.0 % of the total interviewed rural households, respectively. (3) The correlation coefficient between household social vulnerability scores and casualties in a storm flood in July 2010 was significant at 0.05 significance level (r = 0.748), which indicated that the selected indicators and their weights were valid. (4) Some mitigation strategies to reduce household social vulnerability to flood hazards were proposed, which included (1) improving the local residents' income and their disaster-related knowledge and evacuation skills, (2) developing emergency plans and carrying out emergency drills and training, (3) enhancing the accuracy of disaster monitoring and warning systems and (4) establishing a specific emergency management department and comprehensive rescue systems. These results can provide useful information for rural households and local governments to prepare, mitigate and respond to flood hazards, and the corresponding strategies can help local households to reduce their social vulnerability and improve their ability to resist flood hazard.
How and Why is Autism Spectrum Disorder Misdiagnosed in Adult Patients? : From Diagnostic Problem to Management for Adjustment

Autism spectrum disorder (ASD) is often overlooked or misdiagnosed in adult patients especially in those with other psychiatric comorbidities. Several reasons possibly account for this fact, for example, difficulty in obtaining accurate developmental history from a patient, insufficient experience among psychiatrists detecting ASD in adult patients, and mild/atypical autistic traits in contrast to prominent symptoms of psychiatric comorbidities. We conducted a search of databases (PubMed, PsycINFO, and ERIC) for relevant articles published from January 2000 to May 2015 and summarized unrecognized or misdiagnosed cases as well as major psychiatric comorbidities among adults with ASD from previous reports. Five disorders, (i.e., schizophrenia, psychotic disorder, bipolar disorder, major depressive disorder, and personality disorder) were specifically highlighted as misdiagnosed psychiatric diseases or comorbidities responsible for unrecognized ASD. This review also proposes plausible pathways for patterns of maladjustment and processes leading to misdiagnosis among adults with ASD, together with necessary approaches to support their goals of a requisite social life. In conclusion, clinicians should be more concerned with correct diagnosis of ASD as well as treatments of psychiatric comorbidities and need perspective of management for better mental health and social adjustment in ASD patients.
Refrigerator Optimal Scheduling to Minimise the Cost of Operation

Abstract The cost optimal scheduling of a household refrigerator is presented in this work. The fundamental approach is the model predictive control methodology applied to the piecewise affine model of the refrigerator. The optimisation could not be solved using off-the-shelf tools, e.g. Multi-Parametric Toolbox, so a binary treebased optimal scheduling algorithm has been developed for this problem.
The Impact of Toxoplasma Gondii on Mitochondrial DNA of Sub-Fertile Men Sperms

Toxoplasmosis is the most common, widespread disease in the world which is caused by Toxoplasma gondii.The objective of the current study is to determine the effect of the Toxoplasma gondii infection on male sperm, especially on the mitochondria of sperm for men who suffer infertility and the possibility of a hereditary mutation. Sixty seminal fluid and serum samples were taken from subfertile patients who attended Teba center for in vitro fertilization / Babylon and similarly samples were also obtained from healthy individuals as a control group, their ages ranged from 20 to 60 years old during the period from 1st may /2016 till 25th January/2017. All samples subjected to the tests included Macroscopic and microscopic examination, molecular methods was used for DNA extraction, amplification and sequencing. Statistical analysis showed non-significant differences (P<0.01) among age groups and ) between rural 41(68%) and urban 19(32%). However, sperm motility and count recorded highly significant differences (P<0.01) in the mean value for healthy (74.85, 68.017) as compared with the patients (10.30, 10.217). There were also a significant differences (P<0.01) in the mean concentration of Ant-Toxoplasma IgG antibody (1.327μ/ml) in comparison with control group (0.564μ/ml). A highly significant differences (P<0.01) was detected when comparing the positive 55(92%) and negative 5(8%) samples for oligospermia and a significant difference (P<0.05) for Asthenospermia 21(35%), 39(65%). Two mutation 2(3%) were detected in the exchange for fifty eight 58(97%) with a highly significant difference (P<0.01). It was found that the mutation occurred in Asthenospermia of ND1 gene in the site SNP T4216C (T to C) and the site SNP C3450T (C to T) of Mitochondrial DNA. This study confirmed that a mutation in the ND1 gene that is located in the mitochondria of sperms, specifically in people who suffer from infertility, is occurred due to Toxoplasma gondii.
Becoming the Boss: Discretion and Postsuccession Success in Family Firms

Family firms can enjoy substantial longevity. Ironically, however, they are often imperiled by the very process that is essential to this longevity. Using the concept of managerial discretion as a starting point, we use a human agency lens to introduce the construct of successor discretion as a factor that affects the family business succession process. While important in general, successor discretion is positioned as a particularly relevant factor for productively managing organizational renewal in family businesses. This study represents a foundation for future empirical research investigating the role of agency in entrepreneurial action in the family business context, which consequently can contribute to the larger research literature on succession and change.
Intima–media complex thickness and carotid atherosclerotic plaque formation in Lublin’s population in the context of selected comorbidities

Abstract Introduction: Atherosclerosis (arteriosclerosis) is a chronic arterial disease of the arteries with chronic inflammatory. The pathology of atherosclerosis is complex, and the atherosclerotic process is multi-factorial, not fully understood. Risk factors of atherosclerotic lesions may include: lipid disorders, hypertension or diabetes. One of the diagnostic methods of discovering atherosclerosis covers the assessment of the intima–media complex thickness by Doppler ultrasonography. Aim: The aim of this report was an evaluation of the relationships between intima–media complex thickness in the right and left carotid arteries and the occurrence of atheromatous plaque in the Lublin population with respect to three possible concomitant medical conditions, mentioned above. Material and methods: A group of 121 subjects was included into the study, all of the participants being residential inhabitants of the Lublin Voivodship. All the participating patients were requested to fill in a questionnaire. After that, the patients were submitted to Doppler sonography concentrated on intima–media complex thickness evaluation. The occurrence of atheromatous plaque was also assessed in obtained sonographic images. Results: There were statistically significant differences for the intima–media complex thickness and for the atheromatous plaque according to all of the reported diseases: hypocholesterolaemia, hypertension and diabetes. Conclusions: The present study confirms that there is a relationship between the thickness of the intima–media complex in the right and left carotid arteries as well as the occurrence of the atherosclerotic plaque regarding the coexistence of specific disease entities in the subjects of the Lublin population.
