Authors: Miura T. , Sato T. , Arima K. , Mukaigawa S. , Takaki K. , Fujiwara T. 
Published: December 2016

AbstractAn ozone production using pulse voltage driven dielectric barrier discharge (DBD) reactor was investigated experimentally to clarify an influence of a duty factor of applied pulse voltage on ozone yield. A square of 10 kV applied voltage was generated using a pulse modulator. Insulated gate bipolar transistor (IGBT) switches were employed to generate the square pulse with 1 kHz in pulse repetition rate. Duty factor of the pulse voltage was controlled in range from 10 to 80% by timing of a gate signal to the IGBT switches. The output voltages of the power supply were applied to a multipoint electrode type DBD reactor in order to operate at low applied voltage. The ozone yield was obtained to be around 100 g/kWh at several thousands ppm ozone production in pure oxygen circumstance at 5 L/min. gas flow. The ozone yield decreased with increasing ozone concentration and was almost independent of the duty factor of square applied voltage under the present experimental condition. Power loss consumed in the pulse modulator was successfully reduced by decreasing duty factor of the output voltage without decrease of the ozone production.
Photocatalytic Decolorization of Reclaimed Water Using Photocatalyst Coated Black Light with Spiral Fluid Flow System
Authors: Ihara Tatsuhiko , Miyoshi Masahiro 
Published: December 2016

AbstractWe designed and assembled a photocatalyst module for water treatment (referred to hereafter as module-I). The module consists of a Pyrex cylindrical tube into which a photocatalyst coated black light (P-BL) tube was inserted, and the admission port for water is attached tangentially to the curved surface of the P-BL tube. The decomposition-rate constant that we obtained by using a 3-ppm methylene blue aqueous solution showed a drastic increase when the fluid velocity exceeded 2 L/min. We think that the fluid velocity of 2 L/min is the turning point at which the flow pattern changes from a laminar flow to a spiral flow turning around the P-BL. We found that module-I is also effective for decomposition of 50 ppb or less concentration levels of dissolved substances such as 4,4'- (1-Methylethylidene)-bisphenol. From the results of decolorization experiments conducted with module-I in which we used 1 L of amber colored reclaimed water (RW) from a circulation toilet system as real waste fluid, we found that RW became transparent within 2-hours of operation at the fluid velocity of 6.1 L/min.

AbstractThe design and construction of a system consisting of a dielectric barrier cell and the electronic instrumentation intended to generate pulsed discharges at atmospheric pressure in water is showed in this paper. Also, the experimental results from the developed advanced oxidation processes (AOPs) are presented. Demineralised water with a conductivity of 5 μS/cm was used in all tests and a non-thermal plasma is produced between two concentric electrodes in a coaxial configuration by applying high voltage pulses which amplitude can be adjusted from 0 to 30 kV. The propagation of the streamers was characterized by means of the obtained waveforms of voltage and current. The concentration of the ozone generated by the discharges was monitored allowing, in this way, to carry out an analysis of the AOPs, and optic spectroscopy was used to study the discharge parameters involved in such a process.

Moving event and moving participant in aspectual conceptions
Authors: Izutsu Katsunobu 
Published: December 2016

Abstract
This study advances an analysis of the event conception of aspectual forms in four East Asian languages: Ainu, Japanese, Korean, and Ryukyuan. As earlier studies point out, event conceptions can be divided into two major types: the moving-event type and the moving-participant type, respectively. All aspectual forms in Ainu and Korean, and most forms in Japanese and Ryukyuan are based on that type of event conception. Moving-participant oriented Ainu and movingevent oriented Japanese occupy two extremes, between which Korean and Ryukyuan stand. Notwithstanding the geographical relationships among the four languages, Ryukyuan is closer to Ainu than to Korean, whereas Korean is closer to Ainu than to Japanese.

Continuum dynamics and the electromagnetic field in the scalar ether theory of gravitation
Authors: Arminjon Mayeul 
Published: December 2016

AbstractAn alternative, scalar theory of gravitation has been proposed, based on a mechanism/interpretation of gravity as being a pressure force: Archimedes’ thrust. In it, the gravitational field affects the physical standards of space and time, but motion is governed by an extension of the relativistic form of Newton’s second law. This implies Einstein’s geodesic motion for free particles only in a constant gravitational field. In this work, equations governing the dynamics of a continuous medium subjected to gravitational and non-gravitational forces are derived. Then, the case where the non-gravitational force is the Lorentz force is investigated. The gravitational modification of Maxwell’s equations is obtained under the requirement that a charged continuous medium, subjected to the Lorentz force, obeys the equation derived for continuum dynamics under external forces. These Maxwell equations are shown to be consistent with the dynamics of a “free” photon, and thus with the geometrical optics of this theory. However, these equations do not imply local charge conservation, except for a constant gravitational field.
Susceptibility of hornbeam and Scots pine woods to destruction by the subterranean termite Reticulitermes lucifugus ROSSI, 1792 (Blattodea: Isoptera)
Authors: Krajewski Adam , Witomski Piotr , Kotarbiński Szymon 
Published: December 2016

Abstract
The article presents the results of tests of the degree of damage to Scots pine (Pinus sylvestris) and hornbeam (Carpinus betulus) woods by the termite Reticulitermes lucifugus. Both wood species are classified as “susceptible to destruction by termites” in the EN 350-2:2000 standard. The procedures described in the ASTM D 3345-08 standard (2009) were applied in the experiments. During laboratory coercion tests, wood samples from these two species were damaged to a degree between light attack and moderate attack with penetration. Recent Scots pine sapwood was damaged to a heavy degree. The results can be associated with the much higher density of hornbeam wood as compared to Scots pine sapwood. The mortality rate of the termites in the test containers with both wood species was similar and low, no greater than 10%. In the light of the results, the classification of the susceptibility of native wood species to termite feeding, as stated in the EN 350-2:2000 standard, appears to be oversimplified.
Styles of coping and the level of dogmatism in utterance texts as an indicator of anxiety in situations of social exposure
Authors: Zinczuk-Zielazna Joanna , Obrębska Monika 
Published: December 2016

Abstract
A study was carried out involving persons representing high-anxious, low-anxious and repressor types according to the classification of Weinberger, Davidson & Schwartz (1979), selected using the Marlowe-Crowne Social Desirability Scale and the trait anxiety scale of the Spielberger State-Trait Anxiety Inventory. In seeking indicators of anxiety in repressors and high-anxious groups, the authors decided to analyse the level of dogmatism observed in utterance texts. The research was intended to determine whether styles of coping with threatening stimuli condition the level of dogmatism, which was regarded as a cognitive defence mechanism against anxiety. The method of formal analysis of texts (speeches given by the participants in a situation of social exposure) was used to identify their level of dogmatism, measured using the Dogmatism Quotient developed by Ertel. The highest value of the Dogmatism Quotient was recorded for repressors, and the lowest for the low-anxious subjects; a similar pattern was also observed for certain particular dimensions of dogmatism. Statistically significant differences in the level of dogmatism were found between the repressor and lowanxious groups and between the high-anxious and low-anxious groups. The study confirmed the previously discovered pattern whereby repressors exhibit more similarities to high-anxious than to low-anxious persons.
Theoretical and experimental studies on hazard analysis of LPG/LNG release: a review
Authors: Bariha Nilambar , Srivastava Vimal Chandra , Mishra Indra Mani 
Published: December 2016

Abstract
The purpose of this study is to analyze the failure and associated hazards of liquefied petroleum gas (LPG) and natural gas (NG) vessels during handling, storage, and transport. The leakage of LPG and NG from the vessels creates major hazards with the loss of containment. In case of fire, an extensive damage to the property (such as building and plants) and the population also occurs. This review is focused on several areas where the work done in the literature is scarce and missing, such as the failure modes of LPG or NG vessels during storage and transport and the estimation of the amount of the leakage and ignition time during these situations. This paper describes the different possible events such as jet fire, fireball, and vapor cloud explosion (VCE) and their mechanisms and the blast effects on the population or the environment. In this paper, all the experimental studies on pool fire, jet fire, boiling liquid expanding vapor explosion, and VCE associated with LPG/LNG have been analyzed. Moreover, modeling approaches and their corresponding equations, computational fluid dynamic approaches, and software used have also been reviewed.

Abstract
Hard-rock mining for metals, such as gold, silver, copper, zinc, iron and others, is recognized to have a significant impact on the environmental media, soil and water, in particular. Toxic contaminants released from mine waste to surface water and groundwater is the primary concern, but human exposure to soil contaminants either directly, via inhalation of airborne dust particles, or indirectly, via food chain (ingestion of animal products and/or vegetables grown in contaminated areas), is also, significant. In this research, we analyzed data collected in 2007, as part of a larger environmental study performed in the Rosia Montana area in Transylvania, to provide the Romanian governmental authorities with data on the levels of metal contamination in environmental media from this historical mining area. The data were also considered in policy decision to address mining-related environmental concerns in the area. We examined soil and water data collected from residential areas near the mining sites to determine relationships among metals analyzed in these different environmental media, using the correlation procedure in the SAS statistical software. Results for residential soil and water analysis indicate that the average values for arsenic (As) (85 mg/kg), cadmium (Cd) (3.2 mg/kg), mercury (Hg) (2.3 mg/kg) and lead (Pb) (92 mg/kg) exceeded the Romanian regulatory exposure levels [the intervention thresholds for residential soil in case of As (25 mg/kg) and Hg (2 mg/kg), and the alert thresholds in case of Pb (50 mg/kg) and Cd (3 mg/kg)]. Average metal concentrations in drinking water did not exceed the maximum contaminant level (MCL) imposed by the Romanian legislation, but high metal concentrations were found in surface water from Rosia creek, downstream from the former mining area.

Globalisation, Trade Openness and Foreign Direct Investment in Romania
Authors: Dima Stela 
Published: December 2016

Abstract
The paper analyses the trend of globalisation, trade openness and foreign direct investments (FDI) in Romania and the link between them in the last 25 years. Data from UNCTAD, World Bank and KOF globalisation index were used in econometrical models testing the link between globalisation, trade openness and foreign direct investment. A strong positive and statistical validated link is found between globalisation and FDI, between trade openness and FDI, and between FDI and globalisation. In the context of Romanian economy, these three phenomena are interrelated and each of them is acting to potentiate the effect of the other. Moreover, a multivariate regression analysis emphasized the dependency between globalisation index and foreign direct investment, trade openness and market capitalisation. These results can be taken into account when national policies aiming to attract FDI and stimulating export-import activities are designed.

Published: December 2016

Abstract
Electron states in Ge/Si heterostructures with nanodisc shaped quantum dots (QDs) were studied using the electron spin resonance (ESR) method. Three ESR signals were observed under light illumination of the samples. The analysis of the angular dependences of the ESR spectra allows one performing signal assignment. Two ESR signals observed in the dark, as well as under illumination, are related to the electrons localized due to the strain at the top edges and base edges of the nanodiscs, while the third ESR signal observed only under illumination is related to the electrons localized in the Si layer above (or under) the central parts of the nanodiscs due to the Coulomb interaction with photoholes. A comparison with ESR results obtained for structures with lens-shaped QDs was performed. It was found that the nanodisc shape is crucial for the simultaneous localization of three electrons with different g values on the same QD. In the case of lens shaped QDs, only two ESR signals corresponding to the electrons localized at the QD top and base edges of QDs were observed.

Abstract
de Freitas Brito, A, Brasileiro Santos, MdS, Coutinho de Oliveira, CV, and da Cruz Santos, A. Postexercise hypotension is volume-dependent in hypertensives: autonomic and forearm blood responses. J Strength Cond Res 33(1): 234–241, 2019—The purpose of this study was to evaluate the effect of 2 sessions of resistance exercise (RE) with different volumes on postexercise hypotension (PEH), forearm blood flow (FBF), and cardiac autonomic balance (LF/HF) in hypertensive elderly woman. The study was conducted with 16 hypertensive elderly (25.7 ± 3 kg·m−², 55.5 ± 3 years) subjected to 3 experimental sessions, i.e., a control session, exercise with a set (S1), and exercise with 3 sets (S3). For each session, the subjects were evaluated before and after intervention. In the preintervention period, blood pressure (BP), FBF, and LF/HF were measured after 10 minutes of rest in the supine position. Thereafter, the subjects were taken to the gym to perform their exercise sessions or remained at rest during the same period. Both S1 and S3 comprised a set of ten repetitions of 10 exercises, with an interval of 90 seconds between exercises. Subsequently, the measurements were again performed at 10, 30, 50, 70, and 90 minutes of recovery (postintervention) in the supine position. Postexercise hypotension (systolic/diastolic) was greater in S3 than in S1 (−26 ± 4/−14 ± 5 mm Hg vs. −18 ± 5/−8 ± 5 mm Hg, p ≤ 0.05). Similarly, FBF and cardiac LF/HF increased in both sessions, being more evident in S3 than in S1 (4.98 ± 0.32 vs. 4.36 ± 0.27 ml·min−1·100 ml−1, p ≤ 0.05; and LF/HF = 1.69 ± 0.225 vs. 1.37 ± 0.13 p ≤ 0.05, respectively). We conclude that a single RE session with 3 series were able to promote higher PEH in hypertensive women, and this phenomenon was accompanied by increased FBF and increased cardiac autonomic activity.
