The Existence of Stable Electron Trajectories in the Atom Proved by the Ether Theory
Authors: Zareski David
Published: January 2018

The electron on a trajectory around a nucleus radiates energy since it is accelerated and, following the classical theories of physics, should fall on the nucleus. But since it does not fall, it exists a cause, not taken into account by these theories, that prevents it from this fall. Indeed, in our precedent publications we showed that the fields and the particles are changes in a specific elastic medium called "ether". In particular, that a particle is a globule called “single-particle wave” that vibrates in the ether and is denoted  . This  that moves at the velocity V of the particle, contains all the parameters relative to it, and modulates the amplitude of the superposition of a wave called “phase-wave”, denoted , (and not ) of phase velocity V_p . In the present paper, one considers that the electron moves on a circle of circumference C, under the attraction of a nucleus.  is then present simultaneously several times, e.g., N times, at each point of this circle, that is, in , which is influenced by these N superpositions, due to the fact that  interferes with itself at each round. It appears then the two possible cases: the resonant and the nonresonant.In the resonant case, C contains an integer number of wave lengths  of  that therefore superposes itself at each round in a constructive addition, and creates a relatively large  , i.e., of a relatively large energy. The electron that radiates then only a limited percentage of its large energy, does not fall on the nucleus.In the nonresonant case, C contains a non-integer number of , then  superposes itself at each round in a destructive addition, and creates a much smaller , i.e., of much smaller energy. The electron that radiates then almost the same energy as in the resonant case, loses in fact a much larger percentage of its energy than in the resonant case, cannot remain in this state.
The Impact of Political Culture on the Human Rights-based Approach to Development in the Central Highlands of Vietnam
Authors: Dang Toan N
Published: January 2018

The Human Rights-based-Approach (HRBA) to development has been endorsed by the United Nations (UN) and development agencies as the preferable approach to development. It has the potential to adequately address poverty in the developing world and to align development work with universal instruments on human rights, such as the Universal Declaration on Human Rights (UDHR) (1948). However, while much has been written about the HRBA as a viable approach to development, little is known about how the HRBA is implemented in practice, especially in non-western settings. This paper provides empirical data from a HRBA-framed poverty reduction project conducted in two ethnic communities in the Central Highlands of Vietnam, undertaken by Action Aid International Vietnam (AAV). The results demonstrate that the adaptation of the HRBA to these two local contexts was not easy or smooth. While there are many dimensions that shape the success of development work, in this article I focus on the ways in which political culture can create obstacles to the implementation of the HRBA. The article concludes by recommending some strategies that work to ameliorate these concerns.

Published: January 2018

Climate change is taking special attention among the economic agents, especially due to the uncertainties and risks associated with it. In countries with a significant share of renewables in their energy matrix, this phenomenon implies on challenges for the energy planning in future scenarios. In this context, this study establishes a correlation between energy security and climate change by understanding the ability to generate hydroelectric power in large-scale hydroelectric (HEP) and small hydroelectric plants (SHP), in the Alto Paranapanema Basin (São Paulo, Brazil), a region with rainfall anomalies and water flow changes due to climate change. This region was chosen based on its future scenarios on climate change, especially those of rainfall anomalies and change in water flow, using the Soil Moisture Accounting Procedure (SMAP) mathematical model. The water flow was simulated in the HidroLab model, resulting in the generation of hydroelectric power. The results indicated a loss of generation capacity, that can be attributed to negative anomalies of rainfall and its direct influence on river flow, which is a fundamental factor in hydropower generation. Thus, this study draws attention to the importance of considering climate vulnerability in energy planning now and in the future.

Published: January 2018

The aim of the study was analysis of the canonical correlations between body posture variables in the sagittal plane and scoliotic variables among school-children. The study included 28 girls aged 7-18. The Moiré photogrammetric method was used in the research. On the basis of the value of spine curvature angle, scoliotic posture: 1-9°; and scoliosis: ≥10° were distinguished. There were 21 (75%) with scoliotic posture and 7 (25%) with scoliosis. In the canonical correlation regarding body posture variables in the sagittal plane, the largest shares concerned: trunk inclination angle (0.035), alpha angle (0.072), angle of chest kyphosis (0.383), length of lumbar lordosis-(-0.301), actual angle of lumbar lordosis/total spine length (-1.067). In the canonical correlation regarding scoliotic variables, the largest shares were related to: shoulder asymmetry – right higher (-0.577), shoulder blade asymmetry – left higher (0.202), absolute pelvis tilt angle (-0.811), coefficient of shoulder asymmetry relative to C7 (0.324), depth of primary curvature/total spine length (0.420), primary curvature angle (0.032), length of secondary curvature/total spine length (-0.003). The high value of the canonical correlation coefficient despite lack of significance (R=0.72963; p=0.40075) indicates the possibility of the occurrence of a strong correlation of both sets of variables that can be demonstrated with a larger sample size. In the selection of scoliosis treatment method, the size of the postural variables in the sagittal plane should be taken into account, and each patient’s case should be individually considered.
The Impact of Information Technology on Industrial Automation – A Critical Evaluation
Authors: George Joshy , MAJ Stanislaw Paul
Published: January 2018

Information Technology (IT) now impacts on all aspects of modern society (personal, commercial and industrial). The advances in IT may broadly be categorized into the following subsets of technologies: integrated circuits, communications, software engineering and Graphical User Interfaces. In the context of Industrial Automation (IA) it can be seen that some communication protocols, for example Modbus which was first introduced in the 1970’s, has under gone numerous updates driven by IT developments with associated considerable improvements in performance and capability. By contrast some, for example HART which was first introduced in the 1980’s, whilst it has undergone revisions it does not fully utilize the capabilities that IT can provide. For higher level IA systems they can be divided into four generations which can each be associated with specific IT developments. The first generation IA system is based on simple Proportional, Integral and Derivative (PID) controllers and ruggedized microprocessor based Programmable Logic Controllers (PLC). IA systems expanded in both complexity and scope through these generations to include Distributed Control Systems (DCS’s) and Supervisory Control and Data Acquisition (SCADA). The fifth generation of IA systems may be associated with IT developments both on and over the horizon that include: Cloud Computing, Cyber Security and Internet of Things. Responses to these technologies include: General Electric (GE) Predix and Siemens MindSphere. Regardless of how IA is categorized there can be no doubt that IT is responsible for major technical developments – a process that is likely to continue.
The Internal Morality of Conscience
Authors: Mangino Dominic R. ,   The National Catholic Bioethics Center
Published: January 2018

This essay challenges the relevance of the primary analogy in Ronit Stahl and Ezekiel Emanuel’s article “Physicians, Not Conscripts: Conscientious Objection in Health Care.” The author then proposes an alternative, classi­cally inspired model of conscience based on the work of E. Christian Brugger, Edmund Pellegrino, and Alasdair MacIntyre. This teleological model enables a more robust analysis of conscience claims than does Stahl and Emanuel’s social-constructivist framework.

The differential relationship between finger gnosis, and addition and subtraction: An fMRI study
Authors: Soylu Firat , Raymond David , Gutierrez Arianna , Newman Sharlene D.
Published: January 2018

The impact of fingers on numerical cognition has received a great deal of attention recently. One sub-set of these studies focus on the relation between finger gnosis (also called finger sense or finger gnosia), the ability to identify and individuate fingers, and mathematical development. Studies in this subdomain have reported mixed findings so far. While some studies reported that finger gnosis correlates with or predicts mathematics abilities in younger children, others failed to replicate these results. The current study explores the relationship between finger gnosis and two arithmetic operations—addition and subtraction. Twenty-four second to third graders participated in this fMRI study. Finger sense scores were negatively correlated with brain activation measured during both addition and subtraction. Three clusters, in the left fusiform, and left and right precuneus were found to negatively correlate with finger gnosis both during addition and subtraction. Activation in a cluster in the left inferior parietal lobule (IPL) was found to negatively correlate with finger gnosis only for addition, even though this cluster was active both during addition and subtraction. These results suggest that the arithmetic fact retrieval may be linked to finger gnosis at the neural level, both for addition and subtraction, even when behavioral correlations are not observed. However, the nature of this link may be different for addition compared to subtraction, given that left IPL activation correlated with finger gnosis only for addition. Together the results reported appear to support the hypothesis that fingers provide a scaffold for arithmetic competency for both arithmetic operations.
Norms and validation of the online and paper-and-pencil versions of the Abbreviated Math Anxiety Scale (AMAS) for Polish adolescents and adults
Authors: Cipora Krzysztof , Willmes Klaus , Szwarc Adrianna , Nuerk Hans-Christoph
Published: January 2018

The Abbreviated Math Anxiety Scale (AMAS) is one of the most popular instruments measuring math anxiety (MA). It has been validated across several linguistic and cultural contexts. In this study, we investigated the extent of administration method invariance of the AMAS by comparing results (average scores, reliabilities, factorial structure) obtained online with those from paper-and-pencil. We administered the online version of the AMAS to Polish students. Results indicate that psychometric properties of the AMAS do not differ between online and paper-and-pencil administration. Additionally, average scores of the AMAS did not differ considerably between administration forms, contrary to previous results showing that computerized measurement of MA leads to higher scores. Therefore, our results provide evidence for the usefulness of the AMAS as a reliable and valid MA measurement tool for online research and online screening purposes across cultures and also large similarity between administration forms outside an American-English linguistic and cultural context. Finally, we provide percentile and standard norms for the AMAS for adolescents and adults (in the latter case for both online and paper-and-pencil administration) as well as critical differences for the comparison of both subscales in an individual participant for practical diagnostic purposes.
The MAX Statistic is Less Powerful for Genome Wide Association Studies Under Most Alternative Hypotheses
Authors: Shifflett Benjamin , Huang Rong , Edland Steven D.
Published: January 2018

Genotypic association studies are prone to inflated type I error rates if multiple hypothesis testing is performed, e.g., sequentially testing for recessive, multiplicative, and dominant risk. Alternatives to multiple hypothesis testing include the model independent genotypic c2 test, the efficiency robust MAX statistic, which corrects for multiple comparisons but with some loss of power, or a single Armitage test for multiplicative trend, which has optimal power when the multiplicative model holds but with some loss of power when dominant or recessive models underlie the genetic association. We used Monte Carlo simulations to describe the relative performance of these three approaches under a range of scenarios. All three approaches maintained their nominal type I error rates. The genotypic c2 and MAX statistics were more powerful when testing a strictly recessive genetic effect or when testing a dominant effect when the allele frequency was high. The Armitage test for multiplicative trend was most powerful for the broad range of scenarios where heterozygote risk is intermediate between recessive and dominant risk. Moreover, all tests had limited power to detect recessive genetic risk unless the sample size was large, and conversely all tests were relatively well powered to detect dominant risk. Taken together, these results suggest the general utility of the multiplicative trend test when the underlying genetic model is unknown.

Published: January 2018

Background: Several studies showed that the addition of trunk muscle or core stability exercises in the sport training programs is an eﬀective prevention of spinal and other musculoskeletal injuries.Methods: Twelve female basketball players performed supervised five-week exercise program focused on strengthening the trunk muscles. The program was performed three times per week during pre-season. Sorensen test, Fitnessgram Dynamic Curl-Up test, Prone Plank test and Side Bridge test were used to evaluate trunk muscles performance prior to and immediately after the exercise program completion and again after a three-month follow up period.Results: The results of Sorensen test and Prone Plank test significantly improved immediately after the program, but values returned to baseline at follow-up. In contrast, the results of Fitnessgram Dynamic Curl-Up test and Side Bridge test improved significantly with exercise program and remained significantly higher also at follow-up.Conclusions: Exercise program with emphasis on strengthening the trunk and core muscles can improve muscle performance, however, the results deteriorate shortly after program termination. In order to achieve long-term results, trunk and core muscle exercises have to be performed on regular basis, hence they must be incorporated into general strengthening programs of basketball players.
Anatomske variacije vej, ki izhajajo iz zgornje mezenterične arterije
Authors: Kocbek Lidija , Zemljič Mateja
Published: January 2018

Superior mesenteric artery, the second ventral branch of the abdominal aorta, supplies the distal duodenum, the small intestine, and the large intestine to the mid transverse colon. Superior mesenteric artery branches include the inferior anterior and inferior posterior pancreaticoduodenal arteries, middle colic artery, right colic artery, ileocolic artery, jejunal and ileal branches. The vascular anatomy of superior mesenteric branches is frequently variant. The explanation of variant vascular anatomy of branches and pathological consequences of diseases which impact the mesenteric vasculature might be due to the changes that appear in the development of ventral splanchnic arteries and their blood supply. Knowledge of mesenterical variations is valuable to radiologists and surgeons.
Maisons en communauté et cabanes dans la toundra
Authors: Brière Andréanne , Laugrand Frédéric
Published: January 2018

Cet article examine deux types d’habitations utilisées par les Inuits de l’Arctique de l’Est canadien : la maison moderne en communauté, qui s’est imposée depuis le lendemain de la Seconde Guerre mondiale, et la cabane dans la toundra (cabin ou shack), qui a connu un véritable engouement avec la sédentarisation permanente. À partir de matériaux ethnographiques relatifs au Nunavik et au Nunavut, les auteurs montrent que les Inuits ne s’approprient qu’en partie l’habitat de type moderne dans lequel ils vivent. Par ailleurs, même si la maison située dans un espace communautaire est aujourd’hui largement acceptée, les Inuits associent toujours la toundra à un espace plus sain et plus régénérant. C’est là qu’ils construisent de nouvelles habitations sous la forme de cabanons aménagés qu’ils s’approprient davantage et qui laissent apparaître encore plus un habitus nomade. L’idée d’une propriété strictement individuelle inquiète toutefois les plus âgés, pour qui nuna, la terre, ne peut faire l’objet d’une réelle appropriation. Ainsi, même s’il existe un mode d’appropriation visible sur le plan linguistique, la maison contemporaine et le cabanon évoquent encore à certains égards la tente et l’iglou. L’habitus nomade semble toutefois à un point tournant.
La quête d’autonomie résidentielle des femmes inuites du Nunavik
Authors: Hervé Caroline , Laneuville Pascale
Published: January 2018

Cet article explore la quête d’autonomie résidentielle des femmes inuites du Nunavik selon une perspective relationnelle. Basé sur des témoignages de femmes au sujet de la crise du logement, il montre les liens étroits entre le surpeuplement des maisons et la violence familiale et met en évidence les limites du système de logement social face aux tentatives de certaines femmes pour sortir de situations familiales difficiles. Loin de refléter un désir d’émancipation féminine et de rupture relationnelle, cette quête d’autonomie s’avère plutôt être une tentative de se procurer un environnement sécuritaire, étape devenue essentielle dans le rétablissement de saines relations sociales pour certaines femmes inuites du Nunavik. L’intérêt de développer une perspective relationnelle sur la question du logement des femmes invite à repenser de façon plus globale les politiques actuelles de logement social qui fournissent aux Inuits, selon la distinction d’Ingold, des abris (buildings) plutôt que de véritables foyers (dwellings).
La création de la réserve de Nutashkuan
Authors: Maltais-Landry Aude
Published: January 2018

Cet article se base sur des récits recueillis dans le cadre d’un projet de recherche en histoire orale mené avec des membres de la communauté innue de Nutashkuan, sur la Côte-Nord, et qui portait sur la création de leur réserve par les Affaires indiennes dans les années 1950. Placés au coeur de la trame narrative, ces récits abordent non seulement la construction des premières maisons, mais aussi l’imposition d’un chef pour la communauté et l’introduction d’une dépendance économique via la distribution de rations et le resserrement des activités productives. L’imbrication de ces histoires permet d’entrevoir l’aménagement d’une réserve comme un espace à la fois physique, social, politique et économique. Au-delà de son ancrage dans un lieu bien précis, cet article ouvre la porte à l’histoire plus vaste de l’imposition de la Loi sur les Indiens aux communautés autochtones du Québec, portée par le point de vue des Innus sur leur propre histoire.
Canative, « Un propriétaire qui fait toute la différence »
Authors: Kermoal Nathalie
Published: January 2018

Alors que les spécialistes ont principalement mis l’accent sur la migration des Premières Nations de l’Alberta vers les villes dans les années 1970 et les années 1980, très peu d’études ont porté leur attention sur le phénomène d’urbanisation des Métis dans des villes comme Edmonton et Calgary. En outre, très peu d’études ont analysé la question du logement autochtone en milieu urbain dans une perspective historique. En se basant sur des entrevues réalisées dans le cadre d’un projet d’histoire orale sur la corporation de logement Canative, sur les souvenirs d’Herb Belcourt (un des fondateurs), sur des sources primaires trouvées dans les archives de Canative et sur des rapports soumis à la Société canadienne d’hypothèque et de logement (SCHL) ainsi que sur des articles publiés dans le quotidienEdmonton Journalet le journal autochtoneTheNative People, l’auteure de cet article propose de combler un vide historique en se concentrant sur l’histoire d’une des plus importantes sociétés de logement autochtone de l’époque du nom de Canative. Cette société a été fondée à Edmonton en 1971 par trois Métis : Herb Belcourt, Orval Belcourt et Georges Brosseau. Plus particulièrement, l’analyse montre comment ces trois visionnaires ont contribué à remodeler le paysage urbain et politique de la ville d’Edmonton, en assurant un logement sûr et stable aux autochtones (Premières Nations et Métis) nouvellement arrivés à Edmonton.

Cet article porte sur la conception d’outils culturellement adaptés d’aide à la décision en aménagement et en architecture développés avec la communauté innue de Uashat et Maliotenam, au Nitassinan. Il illustre la pertinence de la recherche-création, fondée sur l’inclusion des savoirs et expériences autochtones, pour élaborer des outils pragmatiques. Ces outils prennent la forme de guides : le premier, pour la rénovation et l’adaptation de maisons, et le deuxième, pour l’aménagement et la requalification de milieux urbanisés. Ils visent à soutenir les communautés autochtones et leurs professionnels de l’aménagement dans trois aspects : enjeux de planification, liens entre formes bâties et aspirations communautaires, et construction de visions collectives pour la transformation durable des milieux de vie. Ces intentions mettent en jeu des méthodes participatives et des processus de consultation qui montrent qu’une telle élaboration d’outils d’aide à la décision permet le renforcement du sentiment de communauté et l’empowerment des utilisateurs.
Étude de l’adsorption du rouge de chlorophénol sur une hydrotalcite calcinée
Authors: Sayah Naima , Bakhti Abdellah , Fagel Nathalie
Published: January 2018

L’élimination de la couleur de solutions aqueuses du rouge de chlorophénol a été étudiée par adsorption sur une hydrotalcite de synthèse calcinée. Le solide [Mg-Al-CO3] a été préparé par coprécipitation à pH constant et selon un rapport molaire Mg/Al = 2. Les études par diffraction des rayons X et spectroscopie infrarouge à transformée de Fourier (FTIR) ont montré que le matériau obtenu correspond aux composés de type hydrotalcite avec une bonne cristallinité. L’interaction de ce matériau avec le colorant montre que la cinétique d’adsorption est rapide et suit une expression de vitesse d’adsorption du second ordre. Les influences du pH, de la concentration de l’adsorbant, de la concentration en rouge de chlorophénol de la solution et d’ions compétiteurs tels que chlorure et carbonate ont été étudiées afin d’optimiser l’adsorption. Le traitement de solutions contenant de 0,015 à 1,5 mmol ∙L-1 de rouge de chlorophénol a donné des résultats prometteurs. La capacité d’adsorption de l’hydrotalcite calcinée est d’environ 1,7 mmol∙g-1. Les hydrotalcites calcinées pourraient constituer d’intéressants supports pour le piégeage du rouge de chlorophénol.
La escritura de Juan José Millás: un doble beneficio para el público lector

Published: January 2018

Mediante una poética coherente que se despliega de forma continuada entre sus producciones de ficción y sus colaboraciones en prensa, el escritor valenciano Juan José Millás coloca en primer plano el poder de la palabra para transformar e incluso crear el mundo, en tanto para él no es posible encontrar una frontera clara entre ficción y realidad. El siguiente trabajo se propone analizar dos de los beneficios que la escritura de Millás ofrece a sus lectores: movilizar el juicio crítico y, de forma paralela, despertar o redescubrir el placer de la lectura.

Desesperados intentos por decir el silencio: la ficción como instrumento de duelo
Authors: Nuckols Anthony
Published: January 2018

Proponemos un análisis de El comprador de aniversarios (2002) de Adolfo García Ortega, publicado a comienzos del boom de la memoria en España, como una narrativa postraumática de duelo. Destacamos la novela entre otras contemporáneas que tratan la guerra civil española por su modo de acercarse al pasado, su uso de la ficción y por su temática. Trazamos los paralelismos que existen entre esta y Dora Bruder (1997) de Patrick Modiano, que pudo tener influencia en la de García Ortega. El resultado de esta narrativa de duelo es otro modo de entender nuestra relación en el presente con otro(s) pasado(s) violento(s).

Published: January 2018

This paper presents the electromagnetic wave (EW) absorption properties in terms of complex permittivity and permeability of novel green composites coconut fiber coir and charcoal powder materials. The samples were fabricated using the raw agricultural waste coconut fiber coir, charcoal powder, epoxy resin and hardener with varied composition. The dielectric properties of the materials were characterized using two-port waveguide measurement method over the X-band frequency (8.2 – 12.4GHz). The average permittivity value measured is approximately 3.00 with 10wt% charcoal has the highest permittivity of 3.59. Apart from that, all samples exhibit good reflection loss of better than -25dB which means more than 99% absorption rate. The result shows the composite material is a promising organic material for electromagnetic absorber applications.
Ant mosaics in Bornean primary rain forest high canopy depend on spatial scale, time of day, and sampling method
Authors: Yusah Kalsum M. , Foster William A. , Reynolds Glen , Fayle Tom M.
Published: January 2018

Background

Competitive interactions in biological communities can be thought of as giving rise to “assembly rules” that dictate the species that are able to co-exist. Ant communities in tropical canopies often display a particular pattern, an “ant mosaic”, in which competition between dominant ant species results in a patchwork of mutually exclusive territories. Although ant mosaics have been well-documented in plantation landscapes, their presence in pristine tropical forests remained contentious until recently. Here we assess presence of ant mosaics in a hitherto under-investigated forest stratum, the emergent trees of the high canopy in primary tropical rain forest, and explore how the strength of any ant mosaics is affected by spatial scale, time of day, and sampling method.

Methods

To test whether these factors might impact the detection of ant mosaics in pristine habitats, we sampled ant communities from emergent trees, which rise above the highest canopy layers in lowland dipterocarp rain forests in North Borneo (38.8–60.2 m), using both baiting and insecticide fogging. Critically, we restricted sampling to only the canopy of each focal tree. For baiting, we carried out sampling during both the day and the night. We used null models of species co-occurrence to assess patterns of segregation at within-tree and between-tree scales.

Results

The numerically dominant ant species on the emergent trees sampled formed a diverse community, with differences in the identity of dominant species between times of day and sampling methods. Between trees, we found patterns of ant species segregation consistent with the existence of ant mosaics using both methods. Within trees, fogged ants were segregated, while baited ants were segregated only at night.

Discussion

We conclude that ant mosaics are present within the emergent trees of the high canopy of tropical rain forest in Malaysian Borneo, and that sampling technique, spatial scale, and time of day interact to determine observed patterns of segregation. Restricting sampling to only emergent trees reveals segregatory patterns not observed in ground-based studies, confirming previous observations of stronger segregation with increasing height in the canopy.

Background

N-acetylcarnosine (NAC), a dipeptide with powerful antioxidant properties that is extensively used as a pharmaceutical prodrug for the treatment of cataract and acute gastric disease, was investigated by molecular dynamics with the GROMACS program in order to understand the solvent effect on peptide conformation of the peptide molecule used as a component of a drug and which presents substantial information on where drug molecules bind and how they exert their effects. Besides, molecular docking simulation was performed by using the AutoDock Vina program which identify the kind of interaction between the drug and proteins. A delivery system based on poly(lactic-co-glycolic acid) (PLGA) nanoparticles (NPs) loaded with NAC (NAC-PLGA-NPs) for the treatment of cataract was prepared for the first time in this study in order to enhance drug bioavailability and biocompatibility. The objective of this work was to prepare and evaluate the structural formulation, characterization, and cytotoxicity studies of NAC-loaded NPs based on PLGA for cataract treatment.

Methods

PLGA and NAC-loaded PLGA NPs were prepared using the double emulsion (w/o/w) method, and characterizations of the NPs were carried out with UV–Vis spectrometer to determine drug concentration, the Zeta-sizer system to analyze size and zeta potential, FTIR spectrometer to determine the incorporation of drug and PLGA, and TEM analysis for morphological evaluation.

Results

NAC-loaded PLGA NPs were successfully obtained according to UV–Vis and FTIR spectroscopy, Zeta-sizer system. And it was clearly observed from the TEM analysis that the peptide-loaded NPs had spherical and non-aggregated morphology. Also, the NPs had low toxicity at lower concentrations, and toxicity was augmented by increasing the concentration of the drug.

Discussion

The NAC molecule, which has been investigated as a drug molecule due to its antioxidant and oxidative stress-reducing properties, especially in cataract treatment, was encapsulated with a PLGA polymer in order to increase drug bioavailability. This study may contribute to the design of drugs for cataract treatment with better reactivity and stability.
Regulation of glucose‐stimulated insulin secretion by ATPase Inhibitory Factor 1 (IF1)

Published: January 2018

ATPase Inhibitory factor 1 (IF1) is an endogenous regulator of mitochondrial ATP synthase, which is involved in cellular metabolism. Although great progress has been made, biological roles of IF1 and molecular mechanisms of its action are still to be elucidated. Here, we show that IF1 is present in pancreatic β‐cells, bound to the ATP synthase also under normal physiological conditions. IF1 silencing in model pancreatic β‐cells (INS‐1E) increases insulin secretion over a range of glucose concentrations. The left‐shifted dose–response curve reveals excessive insulin secretion even under low glucose, corresponding to fasting conditions. A parallel increase in cellular respiration and ATP levels is observed. To conclude, our results indicate that IF1 is a negative regulator of insulin secretion involved in pancreatic β‐cell glucose sensing.
Intraplate Deformation of Oceanic Crust in the West Somali Basin: Insights From Long‐offset Reflection Seismic Data

Interpretation of new high‐resolution seismic reflection sections reveals intraplate deformation of oceanic crust in the West Somali Basin, between the East Africa margin and the Davie Ridge and its northern extension. The deformation of the oceanic crust takes the form of 1–2 km amplitude buckle folds with a 20–30 km wavelength associated with thrust faults. Reverse faulting is localized along deformation corridors, about 15–30 km wide that we interpret as inherited oceanic fracture zones of the extinct oceanic spreading center. Deformation of the oceanic crust in the westernmost segment started before Hauterivian time (~132 Ma), while oceanic accretion was ongoing to the east of the Davie Ridge, and stopped at Aptian time (~120 Ma), when spreading ceased in the whole Somali Basin. Prior to the deformation of the oceanic crust, large volcanic edifices have been emplaced on top of the oceanic crust along preexisting oceanic fracture zones. Well‐defined groups of reflectors, within the mantle (<~20 km below top basement), are interpreted as large shear zones that tapped a connection to deep lithospheric melt channels leading to magmatic intrusions within the crust and emplacement of postseafloor‐spreading volcanic edifices within deformation corridors.

The purpose of this paper is to clarify the causal relationship between certain factors through longitudinal research on health and living environment. Based on a questionnaire survey administered online to 5000 Japanese women in February 2011, and a follow‐up survey of 3053 subjects undertaken in February 2013, an analysis was performed on 1575 people with a history of low back pain. First, causal relationships between 2 factors, “Chronic low back pain” and “Stress and fatigue,” were analyzed using cross‐lagged effects modeling and synchronous effects modeling. Similarly, causal relationships between 2 factors, “Stress and fatigue” and “Satisfaction with living environment,” were analyzed using the 2 models. It was revealed that “Satisfaction with living environment” affects “Stress and fatigue,” and “Stress and fatigue” affects “Chronic low back pain.” Covariance structure modeling was used to show that “Satisfaction with living environment” indirectly affects “Chronic low back pain” through “Stress and fatigue” using longitudinal data. Accordingly, it was shown that improving the satisfaction with living environment can improve health in terms of stress, fatigue, and chronic low back pain. Moreover, it was suggested that CASBEE Health Checklist 6 score (group with good housing environment) and health variables were related.

Project for a music school. Due to the superfluous consciousness of ambient noise and sound insulation, many music college facilities employ a style in which the exterior appears as a closed box and the lesson rooms are lined up along corridors in a jail‐cell‐like manner in the interior. In this project, we tried to break down such an image. By exposing the volume of the lesson rooms to the exterior, small, uneven, courtyard‐like spaces between neighboring rooms were created, and the volume of the building was broken down. As a result, the characteristic “porous” volume arrangement was born. For such adjustments, it was more appropriate to use a new computer‐based method of design that incorporates three‐dimensional feedback loops. The porous figures embed a sense of continuity and surprise, as if one were wandering around a village. This resulted in the creation of rich spaces and enhanced presence as a whole.
Iron Oxide Nanoparticle‐Based Magnetic Ink Development for Fully Printed Tunable Radio‐Frequency Devices

The field of printed electronics is still in its infancy and most of the reported work is based on commercially available nanoparticle‐based metallic inks. Although fully printed devices that employ dielectric/semiconductor inks have recently been reported, there is a dearth of functional inks that can demonstrate controllable devices. The lack of availability of functional inks is a barrier to the widespread use of fully printed devices. For radio‐frequency electronics, magnetic materials have many uses in reconfigurable components but rely on expensive and rigid ferrite materials. A suitable magnetic ink can facilitate the realization of fully printed, magnetically controlled, tunable devices. This report presents the development of an iron oxide nanoparticle‐based magnetic ink. First, a tunable inductor is fully printed using iron oxide nanoparticle‐based magnetic ink. Furthermore, iron oxide nanoparticles are functionalized with oleic acid to make them compatible with a UV‐curable SU8 solution. Functionalized iron oxide nanoparticles are successfully embedded in the SU8 matrix to make a magnetic substrate. The as‐fabricated substrate is characterized for its magnetostatic and microwave properties. A frequency tunable printed patch antenna is demonstrated using the magnetic and in‐house silver‐organo‐complex inks. This is a step toward low‐cost, fully printed, controllable electronic components.
