Influence of Transition Metals on Animal and Human Health: A Review
Authors: Bilčíková Jana , Fialková Veronika , Kováčiková Eva , Miškeje Michal , Tombarkiewicz Barbara , Kňažická Zuzana 
Published: January 2019

SummaryNiobium, osmium, scandium, tungsten and vanadium are transition metals naturally occuring in the environment, particularly in the Earth’s crust. Anthropogenic activities, primarily industrial technologies, have precipitated significant alternations in the concentration and distribution of these metals. Such a dramatic change resulted, by all means, in the bigger potential of the environmental exposure, which poses a threat not only to humans but to all biological systems. Certain elements naturally occur in the animal and human plasma and tissues, but their concentrations are sometimes too low to be detected using the existing modern technologies. In small amounts, such elements are not harmful and some of them have even been suggested to have a beneficial role in the human or animal physiology. However, exposure to excessive antropogenically elevated levels can exert serious negative effects on the environment, agriculture and health. The findings summarized in this paper provide a review of the current knowledge about the implications of the transition metals considered on the health, accentuating the insufficiency and need for more relevant data.
Influence of the Storage Period on the Quality Characteristics of Table Eggs
Authors: Stojčić Mirjana Đukić , Perić Lidija 
Published: January 2019

Summary
The purpose of this study is to examine the effects of the storage period on the quality characteristics of Bovans Brown table eggs. Eggs from 47-week-old hens were sampled on the day of laying and stored in a refrigerator (4°C) for periods of 7, 14, 21, and 28 days. Measurements were performed for each storage period relative to the most important quality parameters of eggs. The following egg parameters were evaluated: weight, weight loss, shell breaking force, albumen height, Haugh units and yolk color. The results obtained show that the albumen height and Haugh unit (HU) were affected by the storage period and are of immense importance. The following parameters were found to be significantly influenced by different storage periods: weight loss (P<0.05), albumen height (P<0.05) and Haugh unit (P<0.01). Rapid reductions in the albumen height were recorded during 7, 14, 21 and 28 days of storage (ranging from 6.90 mm to 6.07mm). Moreover, the Haugh unit values also decreased during storage from 81.27 to 74.89 at 4°C. The present results suggest that the albumen height and the Haugh unit are the most important parameters of egg quality, obtained from commercial layers raised in battery cages, affected by a storage period of 4 weeks.
Creativity’s Need for Relevance in Research and Real Life: Let’s Set a New Agenda for Positive Outcomes
Authors: Kaufman James C. 
Published: January 2019

Abstract
Despite an ongoing surge of interest in creativity (both in academia and the public eye), it is essential that researchers focus on why creativity matters. Studies that empathize variables that help increase creativity are absolutely valuable, but I argue that need more work on how creativity can lead to positive outcomes. Much of the existing literature examines how creativity can improve school or work performance – which it does. Yet when these studies are compared with similar ones on conscientiousness, it is hard to argue that increasing creativity is the best way to succeed in school or work (at least using traditional metrics). I argue that as a field, we need to expand our ideas about how creativity can be beneficial. I end with an open call for suggestions.
The Creative Problem Finding Hierarchy: A Suggested Model for Understanding Problem Finding
Authors: Abdulla Ahmed M. , Cramond Bonnie 
Published: January 2019

Abstract
This paper proposes a model, which hopefully will allow researchers in the psychology of creativity to confirm that the different levels and different labels for problem finding can be unified under one construct - problem finding (PF). Although no clear distinctions are made among the levels and terms used in the PF literature, the current efforts suggest that there are important differences that can be explained by (a) how well- or ill-defined a problem is, and (b) the degree to which ideation and evaluation are required. Based on these two criteria, a rubric is presented that allows distinctions to be made among five the PF processes: (a) problem discovery, (b) problem formulation, (c) problem construction, (d) problem identification, and (e) problem definition. The authors examined the literature on PF in English from 1960 to 2015 using the following databases: (a) Academic Search Premier, (b) PsycARTICLES, (c) PsycINFO, (d) Dissertation Abstract, (e) Educational Resources Information Center (ERIC), (f) Psychology & Behavioral Science Collection, and (g) the Google Scholar. This search resulted in 199 articles in which at least 13 different terms were used to describe the process of finding a problem. Only a few articles endeavored to distinguish among the terms used in the literature. This paper concludes by suggesting that one term (i.e., problem finding) is to be used to avoid confusion. If this is not possible, for whatever reason, the term used instead should be defined and the reasons for the choice of terms clearly stated.
Burned Out Myths and Vapour Trails: Vaporwave’s Affective Potentials
Authors: Killeen Padraic 
Published: January 2019

Abstract
As a “born digital” audiovisual music genre and visual aesthetic, vaporwave channels remnants of popular culture, advertising, and consumer technology from the 1980s and early 1990s. retrieving the strange sense of affective potential that still echoes within the outmoded, depleted myths of that era. In doing so, it opens up a unique vantage-point on our present moment, and our contemporary attachments to digital media and a still unrelenting consumer culture. Just as Walter Benjamin believed “revolutionary energies” to resound in the outmoded objects of nineteenth century culture, vaporwave invites us to recognise the affective potentials still incipient in the sounds and images of the recent past and, in doing so, to acknowledge the affective potential available in our own cultural moment.
Integrated Production of Biofuels and Succinic Acid from Biomass after Thermochemical Pretreatments

Published: January 2019

Abstract
The aim of this study was to develop an effective thermochemical method for treatment of industrial hemp, in order to increase its bioconversion to biofuels and bio-products. Industrial hemp was subjected to various thermochemical pretreatments using: alkaline (3 % NaOH), oxidative (3 % H2O2 at pH 11.5) and glycerol-based methods (70-90 % of glycerol, 1-3 % NaOH), prior to enzymatic hydrolysis with Cellic® CTec2/Cellic® HTec2 (15 FPU∙g−1 glucan). Innovative pretreatment with glycerol fraction (80 % glycerol content, 2 % NaOH, 12.5 % biomass loading) showed to be superior over commonly used alkaline and oxidative methods with respect to by-products generation and sugar losses. Integrated process of ethanol production from enriched cellulose fraction (172 kg EtOH∙Mg−1 of dry hemp) and succinic production from xylose-rich residue after ethanol fermentation (59 kg∙Mg−1 of dry hemp) allowed to convert about 97 % of sugars released (glucose and xylose) during enzymatic hydrolysis of pre-treated biomass. The present study showed that it is possible to replace 50 % of the costly yeast extract, used during succinic fermentation as nitrogen source, by alternative nitrogen source (rapeseed cakes) without significant deterioration of succinic yield. Pretreatment liquor after lignin precipitation (52 kg∙Mg−1 of biomass treated) exhibited a high biodegradability (92 %) and allowed to produce 420 m3 CH4/Mg VS). Results obtained in this study clearly document the possibility of biofuels (bioethanol, biogas) and bio-chemicals production from industrial hemp, in a biorefinery approach.

Published: January 2019

Abstract
The Typic Hapludalfs soils under two old shelterbelts (200 years old) Robinia pseudacacia and Crataegus monogyna, multi species of trees (young shelterbelt - 20 years old) and neighbouring cultivated fields were investigated. The function of shelterbelts of different age and plant composition in agricultural landscape and estimation of biochemical and chemical soil conditions for the decrease of greenhouse gases release from soil to the atmosphere was the aim of the research. In soils under shelterbelts were estimated activities of several enzymes participating in the oxidation-reduction processes, ferric and ferrous ions and the evolutions of gases like N2, N2O, CO2, and CH4. The soils under old shelterbelts characterized higher peroxidase activity than in young shelterbelt and adjoining cultivated fields. However, no significant differences were observed for nitrate reductase activity between old and young shelterbelts. There were proved differences between emission of N2O in soils under shelterbelts and in adjoining cultivated fields. Furthermore, it was observed significant effect of the young shelterbelt on the decrease of carbon dioxide release than in the adjoining cultivated field. The manipulation of the landscape through the introduction of shelterbelts of different age and the composition of plants leads to the modification of biogeochemical soil conditions for N2O and N2 formation and finally decrease of the greenhouse gases evolution from soils to the atmosphere. Thus the creation of new shelterbelts is favourable factor for agricultural landscape.
Hit evaluation of an α-helical peptide: Ala-scan, truncation and sidechain-to-sidechain macrocyclization of an RNA polymerase Inhibitor

Published: January 2019

Abstract
RNA polymerase (RNAP) remains a relatively underexplored target with only rifampicin and fidaxomicin in clinical use. Hence, the concurrent rise in bacterial resistance rate urges the search for novel RNAP inhibitors with a novel mode of action. In this work, we investigated the impact of several systematic modifications including sidechain-to-sidechain macrocylization in the α-helical content and biological activity of a previously identified inhibitory sigma factor fragment. Ala-scan results, peptide truncation from both the N- and C-terminus and modifications inspired by other RNAP inhibitors revealed novel structure activity relationships but did not yield a superior sequence. Additionally, four insertion points for non-natural amino acids bearing side chains required for macrocylization were explored. Linear precursors showed improved stabilization of the α-helical content compared to the original sequence as demonstrated by circular dichroism (CD) spectroscopy. However, this increase in α-helicity did not translate into improved biological activity. Instead, complete abolishment of RNAP inhibitory activity occurred. We hypothesize three possible reasons for such a discrepancy and offer the basis for further optimization efforts for this peptidic RNAP inhibitor.
Randomization Tests that Condition on Non-Categorical Covariate Balance
Authors: Branson Zach , Miratrix Luke W. 
Published: January 2019

Abstract
A benefit of randomized experiments is that covariate distributions of treatment and control groups are balanced on average, resulting in simple unbiased estimators for treatment effects. However, it is possible that a particular randomization yields covariate imbalances that researchers want to address in the analysis stage through adjustment or other methods. Here we present a randomization test that conditions on covariate balance by only considering treatment assignments that are similar to the observed one in terms of covariate balance. Previous conditional randomization tests have only allowed for categorical covariates, while our randomization test allows for any type of covariate. Through extensive simulation studies, we find that our conditional randomization test is more powerful than unconditional randomization tests and other conditional tests. Furthermore, we find that our conditional randomization test is valid (1) unconditionally across levels of covariate balance, and (2) conditional on particular levels of covariate balance. Meanwhile, unconditional randomization tests are valid for (1) but not (2). Finally, we find that our conditional randomization test is similar to a randomization test that uses a model-adjusted test statistic.

Abstract
Vacuumcircuit breaker (VCB) is one of the important elements in the power grid that can control and protect the system. The diagnosis of the vacuum arc images in VCBs is helpful to the study on their breaking performance. But up to now, there are few reports on the macro-particle motion trajectories in the arc. As the macro-particles in the arc are flowing, the particle image velocimetry (PIV) can be grafted into the vacuum arc image processing. In this paper, the power frequency vacuum arc (peak is 6.9kA) was used as the treatment object, geometric characteristics of the vacuum arc shape using digital image processing technology were extracted, and the two dimensional motion trajectory and velocity distribution of the arc macro particles in different arc combustion stages were obtained based on 2D-PIV technology. Three stages were analyzed. In the rapid diffusion stage, the collision of the macro-particles is very intense in the anode region, and they spray along the anode surface. In the stable combustion stage, the velocity of the particles near the anode is small, and there is a smaller shrink. And finally in the extinction stage, their motion trajectories are in a state of rotation, near the anode and cathode are in a state of contraction.
Parametric simulation analysis and reliability of escalator truss

Published: January 2019

AbstractEscalators are now more and more widely used around the world. As escalator accidents occur from time to time, it is very important to analyze the structure and reliability of escalators. This paper studies the structure and reliability analysis methods of typical escalators. By applying parametric analysis methods, the efficiency and accuracy of escalator structure analysis are greatly improved. Because the failure of each structural member of the escalator truss system is dependent, this paper applies the dependent failure reliability modeling method and analyzes the reliability of the escalator truss system. The results show that the reliability analysis method of the truss system after considering the dependent failure is more reasonable. The above research work has certain reference significance for the design and analysis of escalators.
Synergy analysis of agricultural economic cycle fluctuation based on ant colony algorithm
Authors: Cheng Shen , A. López Miguel 
Published: January 2019

Abstract
The measurement of the agricultural economic cycle and its synergy analysis are of great significance for the formulation of agricultural macroeconomic policies. When the traditional methods are used to analyze the main factors affecting the synergy of agricultural economic cycle fluctuations, almost all of them use the correlation coefficient or the degree of agreement to express the degree of economic cycle synergy. It is impossible to accurately evaluate the degree of synergy of economic cycle fluctuations. To solve this problem, a quantitative calculation model of agricultural economic cycle synergy evaluation based on the ant colony algorithm is proposed. On the basis of the collected monthly data of agricultural economic operation indicators, a prosperity index that comprehensively reflects the development of agricultural economy is constructed. The law of economic prosperity cycle fluctuation is analyzed according to economic prosperity index, and HP filtering is utilized to decompose the trend fluctuations of the economic time series of various industries and obtain the fluctuation components. The ant colony algorithm is utilized to optimize the spearman correlation analysis method, and the correlation analysis of the wave components is carried out. The Fisher-z conversion is performed on the optimal Spearman correlation coefficient obtained by the optimization. The transformed results represent the degree of economic cycle synergy, considering the geographical distance, economic space spillover, fiscal policy synergy, regional income gap and geographical neighbors, a quantitative calculation model for agricultural economic cycle synergy evaluation is established. The results show that the agricultural economic cycle has a certain spatial correlation, and will expand the agricultural economic fluctuations and form the cycle synergy through the periodic space overflow.
AI for the Common Good?! Pitfalls, challenges, and ethics pen-testing
Authors: Berendt Bettina 
Published: January 2019

Abstract
Recently, many AI researchers and practitioners have embarked on research visions that involve doing AI for “Good”. This is part of a general drive towards infusing AI research and practice with ethical thinking. One frequent theme in current ethical guidelines is the requirement that AI be good for all, or: contribute to the Common Good. Butwhat is the Common Good, and is it enough to want to be good? Via four lead questions, I will illustrate challenges and pitfallswhen determining, from an AI point of view,what the Common Good is and how it can be enhanced by AI. The questions are: What is the problem / What is a problem?, Who defines the problem?, What is the role of knowledge?, and What are important side effects and dynamics? The illustration will use an example from the domain of “AI for Social Good”, more specifically “Data Science for Social Good”. Even if the importance of these questions may be known at an abstract level, they do not get asked sufficiently in practice, as shown by an exploratory study of 99 contributions to recent conferences in the field. Turning these challenges and pitfalls into a positive recommendation, as a conclusion I will draw on another characteristic of computer-science thinking and practice to make these impediments visible and attenuate them: “attacks” as a method for improving design. This results in the proposal of ethics pen-testing as a method for helping AI designs to better contribute to the Common Good.
The urgency of engaging with oddities and ambiguities: Reciprocity and cooperation visited as semio-aesthetic notions in bridging nature and culture
Authors: Chien Jui-Pi 
Published: January 2019

Abstract
The notion of the third culture forms the background of the study that seeks to unify humanistic and scientific approaches for a better appreciation of nature, culture, and the arts. This study draws on the kind of emotion and attitude that we may intuit and act out soon after noticing another individual demanding our help in nature and culture. Such feelings as sympathy and empathy, uncertainty and ambiguity, are perceived to be extremely useful in the context of strategy formation and action taking. These preverbal traits that are already more or less encoded in our body and mind may enable us to devise rewarding strategies emerging from the deep inside when we are coping with strange oddities in nature and culture. Such operation is seen on the one hand to save our biologically valuable time in terms of thinking and imagining, and on the other, to achieve brilliant interpretations of various art and life forms. This study reveals that we are estimated to come up with: (1) cogent and digestible propositions; (2) sharpened perceptions and refined tastes; (3) widened horizons of emulating and appreciating types of art and artifice. On top of polishing our own skills and swiftness of inventing strategies, we may also expect to forge encouraging and endearing partnerships between diverse life forms and us. All in all, this study develops the semio-aesthetic idea that we serve the community by way of developing balanced and intriguing viewpoints that may inspire individuals to regain linkages with beings and forms appearing unpleasant or unconvincing at first sight.
polyRAD: Genotype Calling with Uncertainty from Sequencing Data in Polyploids and Diploids
Authors: Clark Lindsay V , Lipka Alexander E , Sacks Erik J 
Published: January 2019

Abstract
Low or uneven read depth is a common limitation of genotyping-by-sequencing (GBS) and restriction site-associated DNA sequencing (RAD-seq), resulting in high missing data rates, heterozygotes miscalled as homozygotes, and uncertainty of allele copy number in heterozygous polyploids. Bayesian genotype calling can mitigate these issues, but previously has only been implemented in software that requires a reference genome or uses priors that may be inappropriate for the population. Here we present several novel Bayesian algorithms that estimate genotype posterior probabilities, all of which are implemented in a new R package, polyRAD. Appropriate priors can be specified for mapping populations, populations in Hardy-Weinberg equilibrium, or structured populations, and in each case can be informed by genotypes at linked markers. The polyRAD software imports read depth from several existing pipelines, and outputs continuous or discrete numerical genotypes suitable for analyses such as genome-wide association and genomic prediction.

Kekerasan seksual yang terjadi pada anak kian meningkat. Anak perempuan lebih rentan menjadi korban keganasan para pelaku yang tidak bermoral. Anak-anak dicabuli, dinodai dan dibunuh seakan nyawa mereka tidak berharga. Hukum perlindungan anak dari kejahatan seksual sudah diterapkan di Indonesia. Akan tetapi, masih diperlukan pencegahan yang bersumber dari dalam diri anak. Pendidikan gender menjadi salah satu upaya perlindungan anak perempuan dari kekerasan seksual. Pendidikan Gender sejak dini ini betujuan agar anak perempuan mulai bisa menjaga diri dari lawan gender mereka. Pendidikan gender dapat disampaikan orang tua kepada anak perempuanya melalui metode hynoparenting menjelang tidur malam. Metode ini memanfaatkan aspek karakteristik anak usia dini dipadu dengan pemanfaatan gelombang theta pada otak. Sugesti hypnoparenting akan bertahan di memori jangka panjang anak sehingga sesuai untuk menanamkan pendidikan gender sejak usia dini.
REKONSTRUKSI MATERI DAKWAH UNTUK PEMBERDAYAAN PEREMPUAN: PERSPEKTIF TEOLOGI FEMINISME

Published: January 2019

Dakwah adalah sebuah kegiatan untuk menyampaikan pesan-pesan agama yang dilakukan oleh seorang da’i. Kegiatan dakwah gencar di laksanakan, akan tetapi dakwah hanya bersifat ukhrawi-oriented, dan bukan sosial-kontekstual. Akibatnya dakwah belum mampu menyelesaikan persoalan ummat yang terkait dengan isu-isu perempuan. Ironisnya, dakwah yang disampikan oleh para da’i justru menambah dan memperkuat beban perempuan dalam kerangkeng agama. Akibatnya perempuan terpasung dalam otoritas teks yang di dalangi oleh laki-laki. Oleh sebab itu, sebenarnya ada yang perlu dirubah dalam dakwah. Salah satunya adalah perubahan konten materi dakwah. Rekonstruksi materi dakwah dilakukan dengan menggunakan analisa teologi feminis dalam hal ini feminis muslim
