Authors: Freedom Nanuru Ricardo , Munir Misnal , Tjahyadi Sindung
Published: May 2019

Development in various sectors of life will certainly have a major impact on society, both positive and negative. One of the negative impacts of modern development is the erosion of the values of the local wisdom of the community, including the values of local wisdom of Sahu people contained in their traditional house called Sasadu. The purpose of this research was to find out the philosophical values contained in Sasadu traditional houses and write them as part of the preservation of the values of community wisdom which would later be useful as a development filter. The method used was a combined method between library research supported by field research. The results found in this research were that the Sasadu traditional house in Sahu tribe community has a long history and traditional architecture which includes (1) social authority values; (2) legal values and social ethics; and (3) a belief system that is still practiced until now. Based on the results of this research, it can be stated that as a tribal community that still holds strong the local traditions of their ancestors (seen from the whole village that still has Sasadu traditional houses), Sahu tribe must prepare themselves by renewing their traditional pattern of view and being open to change without abandoning their religious social values, so as to anticipate the swift flow of modern development.

Proactive Personality, Career Success, dan Career Adaptability pada Karyawan PT Kereta Api Indonesia Daop 8 Surabaya
Authors: Agustina Tri Siwi , Muhammad Ivan Rizky
Published: May 2019

Proactive personality is an important factor in a boundaryless career. The reason is, in the boundaryless career period, the work environment becomes uncertain and the challenges in a career are increasingly complex. Therefore, there is a need for an adaptive attitude in running a career. Proactive personality is seen as a form of career adaptability. This study analyzes the rela- tionship between proactive personality, career adaptability and career success (subjective and ob- jective). Samples from this study are 41 people from employees of PT KAI DAOP 8 Surabaya which is included in the State-Owned Enterprises (BUMN). The respondents’ data were analyzed using Partial Least Square (PLS) using the SmartPLS 3.0 program. The results of this study indicate that when proactive personalities increase, career adaptability and subjective career success will in- crease too. While the other results of this study are when proactive personality increases, it does not significantly influence objective career success. Similarly, increasing career adaptability does not significantly influence objective career success.
Pengaruh Proactive Personality dan Organizational Support for Career Development terhadap Career Success melalui Career Commitment yang Dimoderasi oleh Self-Efficacy (Studi pada PT Bogasari ISM Flour Mills Tbk. Surabaya)

Published: May 2019

Career success is a way for individuals to fulfill their needs for achievement and effort during work, even career success is someone’s goal in working. The sample in this study were 65 production department employees with quantitative analysis approaches. In this study using PLS (Partial Least Square) analysis with SmartPLS 3.0 software. Research on career success benefits both individuals and organizations. At the individual level, career success can be observed from the objective (extrinsic) and subjective (intrinsic). Knowledge of career success helps individuals de- velop the right strategies to commit to careers in their working days. At the organizational level, knowledge of the relationship between proactive personality and organizational support for career development towards career success can help companies to design effective career systems. Compa- nies that want to get competent human resources must understand the factors that affect their employees’ career success, one of these factors is self-efficacy. The self-efficacy variable in this study is positioned as a moderator that influences the relationship between career success and career commitment. The purpose of this paper is to develop conceptual models and propose hy- potheses that connect proactive personality and organizational support for career development in career success through career commitment that is moderated by self-efficacy.
The burden of foodborne diseases reducing ways
Authors: Kolodnitska T.L. , Selezniova V.O.
Published: May 2019

Introduction. The burden of foodborne diseases is increasingly attracting WHO attention and heightening the necessity of international global public health commitments.

The Aim of the Study is to analyze and summarize the existing national and international experience in reducing the burden of foodborne diseases on the basis of studying legislative and regulatory documents, sources of statistical data, scientific publications and materials of the First FAO/WHO/AU International Food Safety Conference Addis Ababa, 12–13 February 2019.

Materials and Methods. The bibliosemantic and analytical methods have been used.

Results and discussion. It is established that today, the lack of data about the burden of foodborne diseases not only does not allow to get an accurate picture of the current situation, but also complicates the evaluation of the effectiveness and resulting quality of preventive measures and strategies. In recent years, Ukraine has witnessed a sharp deterioration in the food safety and quality situation due to the demonopolization of the food industry, increased volumes of supplies from abroad, weakening of the control over the production and sale of food products. Unresolved issues remain regarding the level of harmonization of Ukrainian legislation with European norms, which is currently insufficient.

Conclusions. In order to reduce the burden of foodborne diseases, the basic principles recommended by the WHO should be taken into consideration: orientation of the measures being implemented to the future, their preventive character, capacity-building in foundational spheres, the integrating efforts and the stimulation of private investment.
A Short Note on Minimal Length
Authors: Moniruzzaman M. , Faruque S. B.
Published: May 2019

After revival of the concept of minimal length, many investigations have been devoted, in literature, to estimate upper bound on minimal length for systems like hydrogen atom, deuteron etc. We report here a possible origin of minimal length for atomic and nuclear systems which is connected with the fundamental interaction strength and the Compton wavelength. The formula we appear at is numerically close to the upperbounds found in literature.
Synthesis and Application to Polyester and Nylon 6 Fabrics of Hetaryl Bis-Azo Disperse Dyes Based on 6-Amino-2,4-Dihydroxypyrimidine and 4-Methoxy-2-Nitroaniline Moieties
Authors: Otutu O. J. , Asiagwu A. K.
Published: May 2019

Six new bis-azo disperse dyes were synthesized by linking various aryl amino and hydroxyl derivatives to 4-methoxy-2-nitroaniline and 6-amino-2,4-dihydroxypyrimidine moieties through diazo coupling reactions. The structures of the bis-azo dyes were identified by Fourier transform infrared, proton and carbon 13 nuclear magnetic resonance data. The prepared dyestuffs were applied onto polyester and nylon 6 fabrics and subsequently their fastness properties in terms of light, washing, sublimation and rubbing were determined. Compared with the light fastness of polyester fabrics, the light fastness of the dyed nylon 6 fabrics were slightly lower. The technical performance of the dyes on the two textile substrates used for the study, demonstrated their useful applications in the dyeing of synthetic fibres.
Evaluation of Aspergillus niger as a Biocontrol Agent in the Insect Pest Management of Red Cotton Bug, Dysdercus koenigii (Heteroptera: Pyrrhocoridae)
Authors: Kumar D. , Kumari S. , Verma D.
Published: May 2019

The present work evaluates the efficacy of Aspergillus niger as a biocontrol agent against Dysdercus koenigii. Three concentrations (C1:1 × 104, C2:1 × 105 and C3:1 × 106 spores/mL respectively) were applied topically to the arthrodial membrane of adult insects and virulence of the fungi in terms of mortality was obtained, which was highest (66.66%) after 96 h post infection with 1 × 106 spores/mL. Its effect on cellular immune response was investigated. The decline in hemocyte count was highest in C3 group treated, i.e. 6992.66±216.34, followed by other groups. Differential hemocyte counts showed that granulocytes and plasmatocytes were the most affected hemocytes with count 26.33±0.66, 24±1.15 respectively in “C3” treated group in comparison to control, 33.66±2.07, 39.66±0.88 respectively. The humoral response was also studied by assessing the activity of four important antioxidant enzymes (superoxide dismutase, catalase, cytochrome p450 and glutathione-S-transferase) and lipid peroxidation that showed significant changes. Based on mortality test we can say that even the sub-lethal concentration can pose significant threat on insect pest. Our results further revealed that Aspergillus niger compromises the immunological parameters of insects and help us understand the underlying mechanism of insect response towards pathogens.
EFFECT OF KINETIC RETURN ANKLE FOOT ORTHOSIS IN PATIENT WITH INCOMPLETE SPINAL CORD INJURY: CHANGES OF THE GAIT PATTERN. A CASE REPORT
Authors: Bergmann Margot , Alvela Mari , Eelmäe Priit , Vahtrik Doris , Gapeyeva Helena
Published: May 2019

Background. The variety of orthotics available induces a purpose for estimation of their influence of functional
mobility for individual needs in people with incomplete spinal cord injuries (ISCI). The aim of the study was to
investigate the effect of the use of kinetic return ankle foot orthosis (KRAFO) on gait pattern in case of ISCI.
Methods. Ankle and knee joint kinematic and kinetic characteristics during gait with and without KRAFO were
studied in a 34-year-old man with ISCI (fracture v.C5) using 3D motion analysis system (Vicon Motion Systems
Ltd., UK) including two dynamographic platforms (AMTI, USA). Ankle and knee joint angles at initial contact and
mid-stance, ankle dorsiflexion and foot progression angle in swing phase and ankle joint push-off values in stance
phase were analysed.
Results. An excessive dorsiflexion in right ankle joint at initial contact, in mid-stance and in swing-phase
occurred when walking without the orthosis, which decreased (105, 57 and 73%, respectively, p < .01) with the use
of KRAFO. Orthoses use evoked the decrease (77%, p < .01) in peak foot progression angle. Ankle joint peak push-
off power was low without the use of KRAFO and decreased even more (28%, p < .05) with the use of orthosis.
Decreases of knee joint flexion angle at initial contact and in mid-stance (29 and 23%, respectively) with the use of
KRAFO were not significant as compared to gait without orthosis.
Conclusions. Walking with KRAFO improved ankle and knee joint stability, providing a decrease in ankle
kinematic characteristics but ankle joint push-off power did not change. Further studies are needed to compare the
effect of KRAFO in comparison with other orthoses on gait pattern in case of ISCI in accordance with the patient-
centric approach for rehabilitation process management.
REDUCED CITRATE SYNTHASE ACTIVITY EFFECT ON OXYGEN CONSUMPTION RATES IN ISOLATED MITOCHONDRIA FROM MICE LIVER AND MUSCLES
Authors: Fokin Andrej , Žūkienė Rasa , Ratkevičius Aivaras
Published: May 2019

Background. Liver and skeletal muscles play the major role in metabolism. Mitochondria are of particular
importance in functioning of these organs. We tested the hypothesis that reduced citrate synthase (CS) activity could
induce improved fatty substrate and carbohydrate oxidation in mitochondria extracted from liver and hind limb
muscles of mice.
Methods. Eight mice each of 12-week-old control C57B6/J (B6) and congenic B6.A-(rs3676616-D10Utsw1)/
Kjn (B6.A) mice were studied. The mitochondria were isolated by differential centrifugation method followed by
assessment of mitochondrial respiration and citrate synthase (CS) activity. Mitochondrial respiration was measured
as oxygen consumption with Clark-type oxygen electrode by using polarography system. CS enzyme activity was
measured spectrophotometrically.
Results. The activity of CS was by ~32% lower for mitochondria for B6.A compared to B6 mice (603.9 ± 135.6 U/g
and 894.2 ± 193.2 U/g, respectively). Mitochondrial respiration did not differ significantly between the strains.
Conclusions. 30% reduction in citrate synthase activity does not impair mitochondrial respiration.
EVALUATION OF EDUCATIONAL SCHOOL ENVIRONMENT AND ACADEMIC SELF-EVALUATION OF ADOLESCENT ATHLETES AND NON-ATHLETES
Authors: Tilindienė Ilona , Šukys Saulius , Kavaliauskas Saulius
Published: May 2019

Background. Grigaliūnienė, Vėlavičienė, Šulga, and Keblys (2007) have revealed that meaningful relationships
with teachers are influenced by positive attitudes towards them with a good emotional atmosphere in the classroom
and a positive microclimate between pupils and teachers. Many scientists point out that education in sports activities
positively impacts the development of adolescents’ communication and collaboration with peers and adults, adequate
self-evaluation and other positive personality characteristics (Kremer-Sadlik & Kim, 2007; Ream & Rumberger,
2008). Research aim was to determine the evaluation of educational school environment and academic self-evaluation
of 11–15-year-old adolescent athletes and non-athletes.
Methods. The research was conducted in 2015. We questioned 209 adolescents, aged 11–15 years. In order to
determine adolescents’ attitudes towards school educational environment, the survey included the following scales:
“Teachers’ help for pupils”; “Support of classmates”; “Positive relationship between adolescents and school”;
“Attitude towards socioeducational school environment”; “Loneliness at school”, and “Academic self-evaluation”.
Results. The survey revealed that boys’ attitudes to socioeducational school environment resulted to be better
than that of girls (p < .05) and that younger adolescents felt more help from the teachers at school than older
adolescents (p < .05), but they also pointed out that they experienced a stronger sense of loneliness at school (p <
.05). More positive relationship was revealed between adolescent athletes and school (p < .05), but adolescent non-
athletes had a better attitude to socioeducational school environment.
Conclusion. It was found that although adolescent non-athletes had a better approach to socioeducational school
environment, their peer reported having a better link with school.
To Be Done with the Possible, To No Longer Possibilate: Considering the Masochist as the Figure of Exhaustion
Authors: van Heerden Chantelle Gray
Published: May 2019

In Coldness and Cruelty, Deleuze remarks that masochism may be reflected on from three perspectives: as a pleasure–pain alliance, as an enactment of humiliation and slavery, and as a consideration of the enslavement of contractual relations. Later Deleuze and Guattari consider masochism in terms of an ontology of desire – in terms of virtuality rather than extensity. I argue that while the actualisation of pain might be considered secondary, and is oftentimes portrayed as incidental in popular depictions, it also constitutes the exhaustive/exhausted and refrain functions of masochism so that the masochist might be thought of as the figure of exhaustion.
Tintoretto: Cosmic Artisan
Authors: Vellodi Kamini
Published: May 2019

The works of the sixteenth-century Venetian painter Jacopo Tintoretto (1518–94) present us with a radicalised idea of the cosmos that challenges both the humanist centring of the world on man and the hierarchy of divine authority that dominate the artistic traditions to which he is heir. In their place, Tintoretto confronts us with a ‘machinic’ staging of forces in which man, nature, religious figure and artificial element are integrated within an extended material plane. With this pictorial immanence, Tintoretto presents a ‘cosmic materialism’ unprecedented in Venetian painting. In this, his work gives provocative expression to Deleuze and Guattari's ontology of the artwork as ‘cosmic’ construction, and to their conception of the artist as ‘cosmic artisan’. Via readings of the art historical reception of Tintoretto's work by the art historian Arnold Hauser (1892–1978), and the artistic reception of Tintoretto's work by Paul Cézanne, I explore this expression, and attend to questions of modernity, temporality and art history as they are inflected in Deleuze and Guattari's thought.
Representations of ṣabr in the Qur'an: A Study on the Imperative (khiṭāb al-amr)
Authors: Abdallahi Tar , Ibrāhīm Al-Shalabī Nahla Zahdī
Published: May 2019

This paper is based in the study of Pragmatics, taking as its starting point the role of the speaker as an agent in the act of communication, and his communicative intent. It will explore occurrences of imperative forms of ṣ-b-r in the Qur'anic text in order to establish its meaning and purpose when used in the imperative (khiṭāb al-amr).

During the research for this study it became clear that ṣabr is a specific concept that has its own significance and distinguishing features, and that it plays a prominent and varied role in the Text. Imperatives derived from ṣ-b-r occur in three forms (namely iṣbir, ṣābir, iṣṭabir), each of which has its own characteristics and stylistic and rhetorical connotations. They primarily occur in the Meccan Qur'an, and are mainly used in passages discussing issues of faith, accounts of the creation of the Heavens and the Earth, or in passages that speak of the Arabs and their reception of Muḥammad's initial prophetic mission while in Mecca.

Published: May 2019

Zinc finger protein 671 (ZNF671) is a member of the largest transcription factor family in the human genome. However, the methylation status, expression, and prognostic role of ZNF671 in solid tumors remain unclear. The aim of this study was to explore the relationship between ZNF671 and the prognosis of patients with solid tumors. We performed a pan-cancer analysis of the methylation status and mRNA and protein expression of ZNF671 using The Cancer Genome Atlas (TCGA) database and the Human Protein Atlas. We further evaluated the prognostic value of ZNF671 expression among numerous cancer types using the “Kaplan–Meier plotter” (KM plotter) database. We found that downregulation of ZNF671 is associated with hypermethylation of its promoter. Survival analysis established that the downregulation of ZNF671 predicts poor prognosis in breast invasive carcinoma (BRCA), cervical squamous cell carcinoma and endocervical adenocarcinoma (CESC), head and neck squamous cell carcinoma (HNSC), kidney renal papillary cell carcinoma (KIRP), lung adenocarcinoma (LUAD), pancreatic adenocarcinoma (PAAD), and uterine corpus endometrial carcinoma (UCEC) solid tumors. CCK-8 and Transwell functional assays showed that ZNF671 could inhibit tumor cell proliferation, migration, and invasion. These results indicate that ZNF671 is an excellent predictive factor for BRCA, CESC, HNSC, KIRP, LUAD, PAAD, SARC, and UCEC solid tumors and may play crucial roles in the development and progression of these tumors.
The Diagnostic and Clinical Utility of Autoantibodies in Systemic Vasculitis
Authors: Csernok Elena
Published: May 2019

Considerable progress has been made in understanding the role of autoantibodies in systemic vasculitides (SV), and consequently testing for anti-neutrophil cytoplasmic antibodies (ANCA), anti-glomerular basement membrane antibodies (anti-GBM), and anti-C1q antibodies is helpful and necessary in the diagnosis, prognosis, and monitoring of small-vessel vasculitis. ANCA-directed proteinase 3 (PR3-) or myeloperoxidase (MPO-) are sensitive and specific serologic markers for ANCA-associated vasculitides (AAV), anti-GBM antibodies are highly specific for the patients with anti-GBM antibody disease (formerly Goodpasture’s syndrome), and autoantibodies to C1q are characteristic of hypocomlementemic urticarial vasculitis syndrome (HUVS; anti-C1q vasculitis). The results of a current EUVAS study have led to changes in the established strategy for the ANCA testing in small-vessel vasculitis. The revised 2017 international consensus recommendations for ANCA detection support the primary use PR3- and MPO-ANCA immunoassays without the categorical need for additional indirect immunofluorescence (IIF). Interestingly, the presence of PR3- and MPO-ANCA have led to the differentiation of distinct disease phenotype of AAV: PR3-ANCA-associated vasculitis (PR3-AAV), MPO-ANCA-associated vasculitis (MPO-AAV), and ANCA-negative vasculitis. Further studies on the role of these autoantibodies are required to better categorize and manage appropriately the patients with small-vessel vasculitis and to develop more targeted therapy.
Assessing the Impacts of Urbanization on Sex Ratios of Painted Turtles (Chrysemys picta)
Authors: Vanek John P. , Glowacki Gary A.
Published: May 2019

Turtles are particularly susceptible to the negative impacts of urbanization due to low mobility and a life history strategy emphasizing long generation times and high adult survival. In addition to declines directly through habitat loss, urbanization has been hypothesized to limit populations of aquatic turtles through changes in population structure, as adult females are disproportionally killed on and near roads, leading to male-biased populations, which can lead to population declines or local extirpations. The purpose of this study was to better understand how urbanization impacts the sex ratios of painted turtles (Chrysemys picta) in an urban ecosystem, as empirical results linking male-biased turtle populations to roads and urbanization are mixed. Using eight years of trapping data from a long-term monitoring program in a suburb of Chicago, IL, USA, we report one of the most male-biased populations ( x ¯ = 75% male) of turtles in the USA, consistent with prevailing road mortality hypotheses. However, we found no evidence that male-biased populations were related to road density or the amount of protected area around a sampling location and found that impervious surface (a metric of urbanization) was weakly related to less male-biased populations. Our results highlight the importance of replicating ecological studies across space and time and the difficulty in assessing population structure in aquatic turtles. We suggest that active conservation measures may be warranted for the continued persistence of urban turtle populations.
Dynamic Lognormal Shadowing Framework for the Performance Evaluation of Next Generation Cellular Systems
Authors: Karagiannis Georgios A. , Panagopoulos Athanasios D.
Published: May 2019

Performance evaluation tools for wireless cellular systems are very important for the establishment and testing of future internet applications. As the complexity of wireless networks keeps growing, wireless connectivity becomes the most critical requirement in a variety of applications (considered also complex and unfavorable from propagation point of view environments and paradigms). Nowadays, with the upcoming 5G cellular networks the development of realistic and more accurate channel model frameworks has become more important since new frequency bands are used and new architectures are employed. Large scale fading known also as shadowing, refers to the variations of the received signal mainly caused by obstructions that significantly affect the available signal power at a receiver’s position. Although the variability of shadowing is considered mostly spatial for a given propagation environment, moving obstructions may significantly impact the received signal’s strength, especially in dense environments, inducing thus a temporal variability even for the fixed users. In this paper, we present the case of lognormal shadowing, a novel engineering model based on stochastic differential equations that models not only the spatial correlation structure of shadowing but also its temporal dynamics. Based on the proposed spatio-temporal shadowing field we present a computationally efficient model for the dynamics of shadowing experienced by stationary or mobile users. We also present new analytical results for the average outage duration and hand-offs based on multi-dimensional level crossings. Numerical results are also presented for the validation of the model and some important conclusions are drawn.
On the Asymmetric Spectral Broadening of a Hydrodynamic Modulated Wave Train in the Optical Regime
Authors: Waseda Takuji , Fujimoto Wataru , Chabchoub Amin
Published: May 2019

Amplitude modulation of a propagating wave train has been observed in various media including hydrodynamics and optical fibers. The notable difference of the propagating wave trains in these media is the magnitude of the nonlinearity and the associated spectral bandwidth. The nonlinearity and dispersion parameters of optical fibers are two orders of magnitude smaller than the hydrodynamic counterparts, and therefore, considered to better assure the slowly varying envelope approximation (SVEA) of the nonlinear Schrödinger equations (NLSE). While most optics experiment demonstrate an NLSE-like symmetric solutions, experimental studies by Dudley et al. (Optics Express, 2009, 17, 21497–21508) show an asymmetric spectral evolution in the dynamics of unstable electromagnetic waves with high intensities. Motivated by this result, the hydrodynamic Euler equation is numerically solved to study the long-term evolution of a water-wave modulated wave train in the optical regime, i.e., at small steepness and spectral bandwidth. As the initial steepness is increased, retaining the initial spectral bandwidth thereby increasing the Benjamin–Feir Index, the modulation localizes, and the asymmetric and broad spectrum appears. While the deviation of the evolution from the NLSE solution is a result of broadband dynamics of free wave interaction, the resulting asymmetry of the spectrum is a consequence of the violation of the SVEA.
Spatiotemporal Clustering Analysis of Bicycle Sharing System with Data Mining Approach
Authors: Ma Xinwei , Cao Ruiming , Jin Yuchuan
Published: May 2019

The main objective of this study is to explore the spatiotemporal activities pattern of bicycle sharing system by combining together temporal and spatial attributes variables through clustering analysis method. Specifically, three clustering algorithms, i.e., hierarchical clustering, K-means clustering, expectation maximization clustering, are chosen to group the bicycle sharing stations. The temporal attributes variables are obtained through the statistical analysis of bicycle sharing smart card data, and the spatial attributes variables are quantified by point of interest (POI) data around bicycle sharing docking stations, which reflects the influence of land use on bicycle sharing system. According to the performance of the three clustering algorithms and six cluster validation measures, K-means clustering has been proven as the better clustering algorithm for the case of Ningbo, China. Then, the 477 bicycle sharing docking stations were clustered into seven clusters. The results show that the stations of each cluster have their own unique spatiotemporal activities pattern influenced by people’s travel habits and land use characteristics around the stations. This analysis will help bicycle sharing operators better understand the system usage and learn how to improve the service quality of the existing system.

Published: May 2019

Cement is one of the construction materials widely used around the world in order to develop infrastructure and it is also one of the factors affecting economies. The production of cement consumes a lot of raw materials like limestone, which releases CO2 into the atmosphere and thus leads to global warming. Many investigations are underway in this area, essentially focusing on the eco-accommodating environment. In the research, an alternative material to cement binder is geopolymer binder, with the same efficiency. This paper presents scanning electron microscope (SEM) and X-ray diffraction (XRD) analysis of factory byproducts (i.e., fly ash and ground granulated blast furnace slag (GGBFS)). The mix design process for the manufacture of alkali-activated geopolymer binders synthesized by fly ash and GGBFS is presented. The mechanical properties (compression, split tensile and flexural strength, bond strength) of geopolymer concrete at different mix proportions and at dissimilar curing conditions were also investigated. Geopolymer concrete synthesized with 30% fly ash and 70% GGBFS has better properties at 14 M of NaOH and cured in an oven for 24 h at 70 °C.
Modified TIG Welding Joint Process: An Approach to Improve Microstructure and Fracto-Mechanical Behavior by MWCNTs Inducement in Al-Mg-Si Alloy

Published: May 2019

This work provides a comprehensive investigation of multi-walled carbon nanotubes (MWCNTs) inducement in weldment and their apparent effect on the microstructure, %elongation and ultimate fracture behavior of Al-Mg-Si alloy referring modified tungsten inert gas (TIG) welding joints. Serious experimental work is carried out at 1 wt%, 1.5 wt%, and 2 wt% of MWCNTs to provide a gradually increasing heterogeneous nucleation. The behavior of grain morphology showed the pure field of epitaxial growth without MWCNTs, and the forestry type morphology for 1 wt% MWCNTs at low welding currents (160 A), though there was a noticeable conversion into equiaxed (EQZ) grains filled with inter-dendritic particles at high welding currents (180 A and 200 A) for 1.5 wt% and 2 wt% of MWCNTs. Moreover, the formation of a cellular type network above the fusion line predominated initially at all parameters. Conversely, fine EQZ grains were formed as they moved upward into the welded zone (WZ) explicitly at a high heat input. A conceptual pictorial model is presented in the study which summarized the behavior of morphological changes at the utilized parameters. The welded joints have demonstrated an increasing trend of strength and %elongation in contrast to joints without added MWCNTs. Comparative results have shown an exceptional increment of 71 to 76% and 67 to 75% of elongation up to ultimate tensile strength (UTS), and a fracture point that was clinched for 1 wt% and 1.5 wt% MWCNTs at 180A. From macro to micro-examination of the fracture surfaces, pure ductile modes constituting elliptical cup and cone type isotropic flow was evident in all specimens. Detailed confirmation of the pull-out fracture mode of MWCNTs has highlighted in the scanning electron microscope (SEM) images that intimated a methodical contribution in load-transfer from matrix to the fiber under axial load. Overall, a concise en-route for MWCNTs inducement is well-appointed through tube fillers along with an activating facilitator (TiO2) in contrast to stereotype fillers for improved behavior termed as modified TIG welding joint process in study.

Published: May 2019

A series of chloralilate-bridged dinuclear lanthanide complexes of formula [{LnIII(Tp)2}2(μ-Cl2An)]·2CH2Cl2, where Cl2An2− and Tp− represent the chloranilate and hydrotris (pyrazolyl)borate ligands, respectively, and Ln = Gd (1), Tb (2), Ho (3), Er (4), and Yb (5) was synthesized. All five complexes were characterized by an elemental analysis, infrared spectroscopy, single crystal X-ray diffraction, and SQUID measurements. The complexes 1–5 in the series were all isostructural. A comparison of the temperature dependence of the dc magnetic susceptibility data of these complexes revealed clear differences depending on the lanthanide center. Ac magnetic susceptibility measurements revealed that none of the five complexes exhibited a slow magnetic relaxation under a zero applied dc field. On the other hand, the Kramers systems (complexes 4 and 5) clearly displayed a slow magnetic relaxation under applied dc fields, suggesting field-induced single-molecule magnets that occur through Orbach and Raman relaxation processes.

Published: May 2019

The discovery of optogenetics has revolutionized research in neuroscience by providing the tools for noninvasive, cell-type selective modulation of membrane potential and cellular function in vitro and in vivo. Rhodopsin-based optogenetics has later been introduced in experimental cardiology studies and used as a tool to photoactivate cardiac contractions or to identify the sites, timing, and location most effective for defibrillating impulses to interrupt cardiac arrhythmias. The exploitation of cell-selectivity of optogenetics, and the generation of model organisms with myocardial cell type targeted expression of opsins has started to yield novel and sometimes unexpected notions on myocardial biology.

Through the use of open data portals, cities, districts and countries are increasingly making available energy consumption data. These data have the potential to inform both policymakers and local communities. At the same time, however, these datasets are large and complicated to analyze. We present the activity-centered-design, from requirements to evaluation, of a web-based visual analysis tool to explore energy consumption in Chicago. The resulting application integrates energy consumption data and census data, making it possible for both amateurs and experts to analyze disaggregated datasets at multiple levels of spatial aggregation and to compare temporal and spatial differences. An evaluation through case studies and qualitative feedback demonstrates that this visual analysis application successfully meets the goals of integrating large, disaggregated urban energy consumption datasets and of supporting analysis by both lay users and experts.

In the United States (U.S.), food fortification and/or enrichment and dietary supplement (DS) use impacts nutrient intakes. Our aim was to examine race/ethnicity and income (Poverty Income Ratio, PIR) differences in meeting the Dietary Reference Intakes based on estimated dietary intakes among the U.S. population age ≥2 years (n = 16,975). Two 24-hour recalls from the National Health and Nutrition Examination Survey (NHANES) cycles 2009–2012 were used to estimate the intake of 15 nutrients as naturally occurring, enriched/fortified, and plus DSs. Across racial/ethnic groups and within PIR categories, significant differences were observed in the %< Estimated Average Requirement (EAR) for vitamin A following enrichment/fortification (E/F) and for vitamin B12 and riboflavin following both E/F and DS use when comparing non-Hispanic blacks, Hispanics, and the other race/ethnicity group to non-Hispanic whites. The %<EAR for iron and calcium also differed depending on race/ethnicity within PIR category (p < 0.05). The %<EAR was significantly lower for vitamin D after E/F for Hispanics, and after E/F combined with DS use for vitamins C and B6 for Hispanics and the other race/ethnicity group than non-Hispanic whites. Non-Hispanic blacks were inadequate in all nutrients examined except vitamin C based on the %<EAR than individuals of other races/ethnicities. Differences in the tolerable upper intake level (UL) of nutrients, especially folate and zinc, also varied by race/ethnicity and PIR category.
Signatures of New Physics Versus the Ridge Phenomenon in Hadron–Hadron Collisions at the LHC
Authors: Sanchis-Lozano Miguel-Angel , Sarkisyan-Grinbaum Edward K.
Published: May 2019

In this paper, we consider the possibility that a new stage of matter stemming from hidden/dark sectors beyond the Standard Model, to be formed in p p collisions at the LHC (Large Hadron Collider), can significantly modify the correlations among final-state particles. In particular, two-particle azimuthal correlations are studied by means of a Fourier series sensitive to the near-side ridge effect while assuming that hidden/dark particles decay on top of the conventional parton shower. Then, new (fractional) harmonic terms should be included in the Fourier analysis of the azimuthal anisotropies, encoding the hypothetical new physics contribution and enabling its detection in a complementary way to other signatures.

Published: May 2019

The thermal behavior of a canned motor also depends on the losses and the cooling capability, and these losses cause an increase in the temperature of the stator winding. This paper focuses on the modeling and simulation of the thermal fields of the large canned induction motor by different calculation methods of water friction loss. The values of water friction losses are set as heat sources in the corresponding clearance of water at different positions along the duct and are calculated by the analytical method, loss separation test method, and by assuming the values that may be larger than the experimental results and at zero. Based on Finite volume method (FVM), 3D turbulent flow and heat transfer equations of the canned motor are solve numerically to obtain the temperature distributions of different parts of the motor. The analysis results of water friction loss are compared with the measurements, obtained from the total losses using the loss separation method. The results show that the magnitude of water friction loss within various parts of the motor does not affect the position of peak temperature and the tendency of the temperature distribution of windings. This paper is highly significant for the design of cooling structures of electrical machines.
The Original Industrial Revolution. Did Cold Winters Select for Cognitive Ability?
Authors: Frost Peter
Published: May 2019

Rushton and Jensen argued that cognitive ability differs between human populations. But why are such differences expectable? Their answer: as modern humans spread out of Africa and into northern Eurasia, they entered colder and more seasonal climates that selected for the ability to plan ahead, in order to store food, make clothes, and build shelters for winter. This cold winter theory is supported by research on Paleolithic humans and recent hunter-gatherers. Tools become more diverse and complex as effective temperature decreases, apparently because food has to be obtained during limited periods and over large areas. There is also more storage of food and fuel and greater use of untended traps and snares. Finally, shelters have to be sturdier, and clothing more cold-resistant. The resulting cognitive demands are met primarily by women because the lack of opportunities for food gathering pushes them into more cognitively demanding tasks, like garment making, needlework, weaving, leatherworking, pottery, and kiln operation. The northern tier of Paleolithic Eurasia thus produced the “Original Industrial Revolution”—an explosion of creativity that preadapted its inhabitants for later developments, i.e., farming, more complex technology and social organization, and an increasingly future-oriented culture. Over time, these humans would spread south, replacing earlier populations that could less easily exploit the possibilities of the new cultural environment. As this environment developed further, it selected for further increases in cognitive ability. Indeed, mean intelligence seems to have risen during recorded history at temperate latitudes in Europe and East Asia. There is thus no unified theory for the evolution of human intelligence. A key stage was adaptation to cold winters during the Paleolithic, but much happened later.
Authentication and Delegation for Operating a Multi-Drone System
Authors: Bae Mungyu , Kim Hwangnam
Published: May 2019

As the era of IoT comes, drones are in the spotlight as a mobile medium of Internet of Things (IoT) devices and services. However, drones appear to be vulnerable to physical capture attacks since they usually operate far from operators. If a drone is illegally captured, some important data will be exposed to the attacker. In this paper, we propose a saveless-based key management and delegation system for a multi-drone control system. The proposed system enables a multi-drone control system to highly resist physical capture by minimizing exposure of confidential data. In addition, when the drone leaves the formation for performing another mission or by a natural environment, the system can allow the drone to securely re-participate in the formation with the help of the ground control station (GCS) when it comes back. The analysis result shows that the proposed system can reduce storage space usage and require less computational overhead. From the result, we expect that the system can guarantee the resistance of physical capture and secure key management to the drones as well as many mobile IoT devices.
Favorability mapping of hydrotermal vein-type lead deposits: a case study in Ribeira Valley, Brazil
Authors: Viltus Joël , Bonfim Marcel de Souza
Published: May 2019

The region of the Ribeira Valley is known for its metallic sulphide deposits (lead, zinc, copper, silver and gold), being the major lead producer of the Brazil in the 1950s. Since then, it has become the target of several geological studies from which two models of lead and zinc mineralization known as Perau and Panelas models were proposed. This study is particularly interested in the Panelas model, which is characterized by its vein morphology, association with carbonate rocks and structural control. Based on literature, this paper proposes to verify the applicability of the hierarchical analysis process (AHP) as auxiliary of the geographic information system (GIS) in the favorability mapping of hydrothermal veins-type Pb deposits which fit in the Panelas model. The study area is the western region of the Ribeira Valley, located in the southern portion of the São Paulo State, Brazil. In order to perform this work, four parameters were used: geological structure, stratigraphy, lithology and geochemistry. The result obtained highlights areas corresponding to Mina de Furnas, Bairro da Serra and Água Clara Formations as highly favorable areas to lead mineralization according this model. In addition, it shows the negative association of these geological formations with potassium concentration.

The taekwondo match is led by a referee and three judges in charge of giving scores to athletes who get points. The position of these judges is at the edge of the determined arena. The judging system requires many devices such as joy-stick, in-focus and a computer that each device must be connected to each other by using a wire, this method is felt to be less effective where the position of the cable should not be touched or trampled by the player or referee in the match area. To overcome this, it is necessary to design a judging system that utilizes Android with wireless networks to make it easier to give points. The judging process as described can be improved by utilizing information technology in the form of an Android smart phone for judging by using an input device in the form of an Android phone that serves to enter points that will later be displayed. The test results show that the application are more compatible with the World Taekwondo Competition Rules & Interpretation 2018 compared to the previous tools that have not been used in the latest regulations
