Authors: Bartlett Rodney
Published: August 2019

The article begins with the physics, cosmology and geometry I’ve been working on for several years (part of the present article uses paragraphs from that earlier work, so you might find them online - there are links to the earlier work on my ORCID page, https://orcid.org/0000-0003-2240-3743). Since the science of Isaac Newton in the second half of the 17th century, we’ve regarded gravity as the product of mass. Then early last century, Albert Einstein's theory of General Relativity revolutionized understanding of gravity - and four years after that (in 1919), he published a paper titled "Do gravitational fields play an essential role in the structure of elementary particles?" Considering Einstein's contributions to science is enough to make us wonder if we should instead regard mass as the product of gravity. That's what the first section of this article does, via a simple mathematics which the author developed for his own comprehension of various sciences, and which he calls "vector-tensor-scalar geometry". The second section proposes that the entire universe (as well as everything in time) is digital in nature, being composed of electronics' binary digits that enter a shortcut through time (a wormhole) in our far future and build the Mobius strips, figure-8 Klein bottles, and adaptive Wick rotation composing space-time. (This section also provides a quantum explanation of the superflow in supersolids.) The final third section speaks of bandgap implants in the brain, and unites them with the first two parts. Then gravitational fields play an essential - indeed, formative - role in the structure of all types of matter plus its strong and weak nuclear forces. In an extension of Morpho butterflies' ability to selectively add and delete wavelengths of light, the implants selectively add and delete "wavelengths of matter" e.g. in future, electronic genetic engineering. Union with the digital universe means surgery will oneday be unnecessary to obtain an implant - it'll simply be a downloaded program.

Executive control and felt concentrative engagement following intensive meditation training
Authors: Zanesco Anthony Paul , King Brandon , MacLean Katherine A. , Saron Clifford
Published: August 2019

Various forms of mental training have been shown to improve performance on cognitively demanding tasks. Individuals trained in meditative practices, for example, show generalized improvements on a variety of tasks assessing attentional performance. A central claim of this training, derived from contemplative traditions, posits that improved attentional performance is accompanied by subjective increases in the stability and clarity of concentrative engagement with one’s object of focus, as well as reductions in felt cognitive effort as expertise develops. However, despite frequent claims of mental stability following training, the phenomenological correlates of meditation-related attentional improvements have yet to be characterized. In a longitudinal study, we assessed changes in executive control (performance on a 32-min response inhibition task) and retrospective reports of task engagement (concentration, motivation, and effort) following one month of intensive, daily Vipassana meditation training. Compared to matched controls, training participants exhibited improvements in response inhibition accuracy and reductions in reaction time variability. The training group also reported increases in concentration, but not effort or motivation, during task performance. Critically, increases in concentration predicted improvements in reaction time variability, suggesting a link between the experience of concentrative engagement and ongoing fluctuations in attentional stability. By incorporating experiential measures of task performance, the present study corroborates phenomenological accounts of stable, clear attentional engagement with the object of meditative focus following extensive training. These results provide initial evidence that meditation-related changes in felt experience accompany improvements in adaptive, goal-directed behavior, and that such shifts may reflect accurate awareness of measurable changes in performance.

Perceived emotional expressions of composite faces
Authors: Kilpeläinen Markku , Salmela Viljami
Published: August 2019

The eye and mouth regions serve as the primary sources of facial information regarding an individual’s emotional state. The aim of this study was to provide a comprehensive assessment of the relative importance of those two information sources in the identification of different emotions. The stimuli were composite facial images, in which different expressions (Neutral, Anger, Disgust, Fear, Happiness, Contempt, and Surprise) were presented in the eyes and the mouth. Participants (21 women, 11 men, mean age 25 years) rated the expressions of 7 congruent and 42 incongruent composite faces by clicking on a point within the valence-arousal emotion space. Eye movements were also monitored. With most incongruent composite images, the perceived emotion corresponded to the expression of either the eye region or the mouth region or an average of those. The happy expression was different. Happy eyes often shifted the perceived emotion towards a slightly negative point in the valence-arousal space, not towards the location associated with a congruent happy expression. The eye-tracking data revealed significant effects of congruency, expressions and interaction on total dwell time. Our data indicate that whether a face that combines features from two emotional expressions leads to a percept based on only one of the expressions (categorical perception) or integration of the two expressions (dimensional perception), or something altogether different, strongly depends upon the expressions involved.
Meaningful change definitions: Sample size planning for experimental intervention research
Authors: Gruijters Stefan L.K. , Peters Gjalt - Jorn Ygram
Published: August 2019

Experimental intervention tests need to have sufficient sample size to constitute a robust test of the intervention’s effectiveness with reasonable precision and power. To estimate the required sample size adequately, researchers are required to specify an effect size. But what effect size should be used to plan the required sample size? Various inroads into how to select the a priori effect size have been suggested in the literature – including using conventions, prior research, and theoretical or practical importance. In this paper, we first discuss problems with some of the proposed methods of selecting the effect size for study planning. Subsequently, we lay out a method that provides a way out of many of these problems. The method requires setting a meaningful change definition, and is specifically suited for applied researchers interested in planning tests of intervention effectiveness. We provide a hands-on walk through of the method and provide easy-to-use R functions to implement it.
Folk Theories of Gender and Anti-Transgender Attitudes
Authors: Rad Mostafa Salari , Shackleford Crystal , Lee Kellie Ann , Ginges Jeremy , Jassin Kate
Published: August 2019

Transgender rights and discrimination against transgender people are growing public policy issues. Theorizing from social, cognitive, and evolutionary psychology suggests that beyond attitudes, discrimination against transgender people may derive from folk theories about what gender is and where it comes from. Transgender identity is met with hostility, in part, because it poses a challenge to the lay view that gender is determined at birth, and based on observable physical and behavioral characteristics. Here, in two pre-registered studies (N = 1323), we asked American adults to indicate the gender of a transgender target who either altered their biology through surgical interventions or altered their outward appearance: to what extent is it their birth-assigned gender or their self-identified gender? Responses correlate strongly with affect toward transgender people, measured by feeling thermometers, yet predict views on transgender people’s right to use their preferred bathrooms above and beyond feelings. Compared to male participants, female participants judge the person’s gender more in line with the self-identified gender than the birth-assigned gender. This is consistent with social and psychological theories that posit high status (e.g., men) and low status (e.g., women) members of social classification systems view group hierarchies in more and less essentialist ways respectively. Gender differences in gender category beliefs decrease with religiosity and conservatism, and are smaller in higher age groups. These results suggest that folk theories of gender, or beliefs about what gender is and how it is determined have a unique role in how transgender people are viewed and treated. Moreover, as evident by the demographic variability of gender category beliefs, folk theories are shaped by social and cultural forces and are amenable to interventions. They offer an alternative pathway to measure policy support and possibly change attitude toward transgender people.
Examining differential item functioning of social interaction and performance fears in people with hazardous alcohol consumption and probable alcohol dependence

Published: August 2019

A growing body of epidemiological evidence has highlighted the significant relationship between social anxiety disorder and hazardous alcohol consumption, harmful use, and alcohol use disorder. This relationship may influence the reporting of fear and avoidance of social or performance situations on common self-report measures among individuals with hazardous alcohol use or dependence. As such, the current study utilised modern psychometric methods, namely Item Response Theory (IRT) and Differential Item Functioning (DIF), in a large online sample of Australian adults (n=1052) to examine the potential under- or over-reporting of items on the Social Interaction Anxiety and Social Phobia Scales (SIAS/SPS) by groups of alcohol users (as measured by the Alcohol Use Disorders Identification Test), while controlling for underlying levels of social anxiety severity. The results indicated that there were no items on the SIAS/SPS that exhibited significant (p<0.01) and meaningful DIF (based on an a priori cut-off of change in pseudo-R2 across nested models >0.05) attributable to either hazardous consumption or symptoms of alcohol dependence. Moreover, the combined effect of multiple items that demonstrated significant (but non-meaningful) DIF on total SIAS scores relative to scores that assume no DIF between alcohol using groups was minimal. These results suggest that different rates of social anxiety across levels of alcohol consumption and alcohol dependence may not be the result of a systematic under- or over-reporting of certain items on the SIAS and SPS, and as such total social anxiety scores can be compared and interpreted regardless of the level of alcohol use or dependence symptoms
Are humans born to hate? Three myths and three developmental lessons about the origins of social categorization and inter-group bias
Authors: Rhodes Marjorie
Published: August 2019

Are humans born to hate? The present chapter considers three common claims about the nature of social categorization—that humans are predisposed to racism, to dislike out-groups, and to think of differences between people in the same way as they think about differences between animal species—and addresses the developmental evidence on which these claims are based. Consideration of the processes underlying the emergence of these phenomena across childhood provides new insight into how to prevent the development of prejudice and improve inter-group relations.

RESEARCH OF CONSEQUENCES OF EMERGENCY SITUATIONS AT THE INDUSTRIAL PIPELINES
Authors: Kryvenko H. M. , Vozniak L. V.
Published: August 2019

The reasons of emergency situations for the long-term operated industrial pipelines were presented. It was revealed that the greatest risk of accidents at these objects is related to longitudinal destruction, which can occur both in the main metal pipes and in the weld zone, due to the formation of corrosive “fistulas” and “guillotine” ruptures. Industrial gas pipelines are objects of high danger. In case of the gas pipeline failure, there is a shock wave, which is one of affecting factors.

The conditional probability of ignition of emergency emissions of hydrocarbon energy carriers was determined, considering the location of ignition sources. The probit-functions by the thermal effect on people were determined. The determination method of emergency gas losses in case of pipeline rupture was developed. A comparative analysis of gas mass flux at pipeline rupture was performed, depending on the pipeline diameter, initial pressure, time and distance from the point of pipe damage.
OPTIMAL DISTRIBUTION OF PARALLEL WORKING EQUIPMENT WITH REGARD TO ENVIRONMENTAL TAXES UNDER UNDERSTANDING CONDITIONS
Authors: Ηorbiychuk M. I. , Bila O. T. , Lazoriv N. T.
Published: August 2019

For a case where the compressor station, where the parallel-supplied gas-pumping units operate, has an excess capacity, the problem of optimal choice of the number of aggregates by a certain criterion arises. The prevailing criterion has two components. The first component is the cost of the fuel gas consumed by the compressor station. The second component is the ecological tax charged for the release of nitrogen oxides into the environment. To calculate the second component, an empirical model is synthesized in the form of a polynomial of a given degree which parameters and structure are determined using genetic algorithms. Such a model characterizes the dependence of the power of emissions of nitrogen oxides on the technological parameters that characterize the process of combustion of natural gas in the combustion chamber.

In the generated problem of power emissions are calculated by the average values of technological parameters, which generates their fuzziness. Each parameter is characterized as the fuzzy value by a triangular membership function that is approximated by the Gaussian function.

The formalized problem of choosing the optimal number of parallel operating units has in its composition the optimality criterion as fuzzy value and the limitations are determined by the given volume of pumped natural gas by the compressor station and the maximum allowable number of aggregates in each group of superchargers.

The introduction of fuzziness generates a discrete nonlinear programming problem with linear constraints. For its solution, the method of boundaries and branches is used, on the basis of which algorithms and software are developed. The software is tested on the developed example, where the data used to determine the operation of the compressor station is used.
THE IMPROVEMENT ON THE EFFICIENCY OF CLEANING GAS PIPELINES FROM LIQUID CONTAMINANTS
Authors: Hrudz V. Ya. , Slobodian N. B.
Published: August 2019

The article considers modern methods of improving the efficiency of pipeline transport cleaning. The most effective method for increasing the efficiency of the gas pipeline is its periodic cleaning with the use of mechanical cleaning units. The reasons for the decrease of efficiency are the presence of fluid in the pipeline interior. Fluid can be in two forms – high-viscosity resin sediments and low-viscosity liquid sediments. Sediments reduce the area of the cross-section and increase the hydraulic resistance. Regardless of the design of the cleaning units, none of them can completely remove liquid contamination. The authors analyze the causes of the flow over the moving boundary. This overflow worsens the quality of gas pipeline cleaning. At the moment when the cleaning piston meets an obstruction of liquid contaminants in the gas pipeline there is a hydraulic impact as a result of which the sealing elements of the piston deform, and part of the fluid overflows into the chamber behind the piston. The authors discover that the increase of cleaning efficiency can be achieved by reducing the amount of pressure increase (which is the result of hydraulic impact) without decreasing the piston speed. The algorithm for improving the efficiency of pipeline cleaning is suggested. It is based on the reduction of over-the-moving-boundary flow by the aeration of the liquid plug. The influence of the gas content of the liquid plug on the amount of the flow in behind-the-piston space has been investigated. A mathematical model of the process was created. On the basis of its implementation the patterns of pressure fluctuations in the gas-liquid medium are established. On the basis of the calculations, the authors have designed the graphic dependence of the pressure change in the liquid phase on the length of the obstruction and the dependence of the pressure on a piston on the gas saturation of the liquid plug.

Pengelolaan keuangan atau manajemen kas sangatlah diperlukan untuk mendukung kemajuan usaha kecil dan menengah. Beberapa usaha kecil dan menengah sekarang ini masih menggunakan cara manual dalam memanajemen keuangannya. Akibatnya permasalahan seperti kesalahan perhitungan atau data keuangan tidak sesuai dengan jumlah real yang ada. Dengan metode apriori yang penulis sederhanakan algoritmanya sesuai kebutuhan aplikasi sehingga dapat membantu pelaku UKM (Usaha Kecil dan Menengah) dalam menghitung secara otomatis keseluruhan data pemasukan dan pengeluaran dalam satu aplikasi, dan juga dapat menampilkan semua data transaksi yang telah berjalan. Model pengembangan aplikasi dibangun dengan metodologi waterfall. Diharapkan aplikasi ini dapat di akses pada device dengan platform Android sehingga bisa membantu pelaku usaha kecil dan menengah dalam menjalankan proses manajemen keuangan sehingga penggunaan kas untuk kebutuhan usaha bisa lebih efisien.

Kaempferia galanga (KG) atau kencur telah lama digunakan masyarakat Asia termasuk Indonesia sebagai obat tradisional dan bumbu masak. Informasi yang konfrehensif botani, metabolit sekunder dan bioaktivitas KG sangat penting untuk pengembangannya sebagai obat tradisional sehingga dapat meminimalisasi efek sampingnya. Penulisan artikel ini didasarkan studi literatur yang diperoleh secara on line maupun off line berupa buku, jurnal maupun hasil penelitian lainnya. KG merupakan tanaman herba aromatis dengan daun biasanya 2-3(-5) dengan seludang 1,5-5 cm, daun sering horizontal dan menutupi permukaaan tanah. Ethyl-trans-p-methoxy cinnamate dan trans-ethyl cinnamate merupakan senyawa utama yang sangat penting pada KG dan merupakan komponen yang memiliki sifat pharmakologi, oleh karena itu penting dilakukan pemilihan aksesi dengan kandungan senyawa bioaktif yang tinggi. Secara etnobotani KG digunakan sebagai obat ekspektorat, karminatif, obat batuk, rematik, dan anti kanker, kolera, vasorelaksasi, anti mikroba, antioksidan, anti alergi penyembuhan luka. Walaupun secara etnobotani banyak manfaat dari KF, namun bioaktivitasnya membuktikan aktivitas KG sebagai anti kanker, anti oksidan, anti inflamasi, analgesik dan anti bakteri

(Un)seen Seas
Authors: Ratté Stephanie
Published: August 2019

Remote technologies and digitally mediated representations now serve as a central mode of interaction with hard-to-reach sea spaces and places. This article reviews the literature on varied scholarly engagements with the sea and on the oceanic application of technologies—among them geographic information systems, remotely operated vehicles, and autonomous underwater vehicles—that allow people to envision and engage with deep and distant oceanic spaces. I focus on the extension of a digital and disembodied human presence in the oceans and the persistence of frontier fictions, in which the sea figures as a site of future-oriented possibilities. Finally, I ask what the emphasis on “seeing” through technological mediation means for how we imagine vast spaces, and consider how these elements of the oceanic imaginary can be productively complicated by drawing attention to the materiality of the oceans and the scalar politics of dynamic spaces.

Today, more than 400 drugs in veterinary medicine are used in three main purposes, in the treatment of microbial infections, infection prevention, and growth promoters in order to achieve a faster animal growth. Residues of medicines in meat and meat products can have a number of negative effects on consumer health, ranging from hypersensitivity to cancerous, mutagenic or teratogenic effects, normal intestinal flora disorders, and antibiotic-resistant bacterial strains. In the European Union (EU), the largest meat producers are Spain, Italy, Germany, Poland, France and the United Kingdom, which also have the largest drug sales. The largest quantities of drugs sold were found for tetracyclines, penicillins and sulphonamides whose combined sales at EU level in 2015 were 69.6 % and in Croatia 76.7 %. EU members under Council Directive 96/23/EC carry out control of residues of veterinary drugs according to national residue monitoring plans (NRMP) in animals used for food production. Screening and confirmatory methods are used to control of drug residues. Most commonly, liquid chromatography in combination with tandem mass spectrometry is used. Today, priority is the development of effective multimethods that allow simultaneous analysis of residues of different antibiotic families. Every year, the European Food Safety Authority (EFSA) summarizes the results of the NRMP of the EU Member States in a joint report. The total number of non-compliant antibiotic results in meat samples in 2015 and 2016 was 250 and 195, respectively. The highest number of non-compliant results was found for tetracyclines. A coordinated and comprehensive control of veterinary medicines is established in the EU necessary for a high level of consumer health protection. The system of regulations just as well as analytical methods are constantly being upgraded and developed.
