Published: November 2019

Total Hip Joint Replacement Surgery is the procedure of surgical removal of cartilage in the hip joints damaged by disease osteoarthritis to replaced with artificial components. Total Hip Joint Replacement has been indicated to relieve pain in the pelvis due to degenerative joint disease. In Indonesia, this procedure has been practised, but due to the cost of expensive products resulting in limited only to upper classify patients. The high prices caused by importing prostheses products, the technological capabilities and the difficulty to meet the standards of medical devices. The regulation of the Minister of Health of the Republic of Indonesia Number 52, 2016 for standard rates in organising health services Health Assurance Program, explained that the action of these operations entered into the insurance claims BPJS program, but not for the prostheses. This paper discusses the introduction of the development of the hip joint prostheses made from a local material that’s SS 316L, PEEK and Ceramic Dental Stone. The result of this development is the product of the hip joint prostheses has a reasonable price with good quality so that it can become affordable for middle to lower patients.

Authors: Bradley Walter L. , Conroy Sean
Published: November 2019

Each year, 64 000 000 000 coconuts are harvested around the world. The coconut water, coconut milk and/are coconut oil are produced from the coconut, leaving behind the coconut shells and the coconut husks, which are not well utilized. Exciting new ways to utilized coconut shell powder as function filler in engineering plastic such as polypropylene or polyethylene and to utilize coir fiber from the husk with polypropylene in non-woven fabric composites. These application demonstrate that the resulting environmental friendly composite materials have enhanced mechanical properties at a reduced cost.

Published: November 2019

The increased number of mobile phone users has an impact on increasing electronic waste (E-Waste) without being offset by the act of product recovery management. Remanufacturing is one way to overcome this. Remanufacturing is a process to return used products to general aesthetics and operating standards.This paper aims to design a mobile phone remanufacturing process in Indonesia. Indonesia is a developing country where mobile usage is quite high. The mobile phones are chosen because it is one of the biggest e-waste takers of late. Several factories were visited in this study. This research uses a qualitative survey, which is carried out in mobile phone factories and service centers. From this research, a design has been made to remanufacture the process on mobile phones. The manufacturing plant verifies the design to obtain the input of the real constraints which will happen when the remanufacturing process is done. The steps in the process of remanufacturing are human machine interface & visual inspection, separation, disassembly, cleaning, inspection, sorting, reconditioning, reassembly, and final inspection.

Authors: Ratna Pratiwi Yuniar , Widiastuti Indah , Harjanto Budi
Published: November 2019

The aim of this article is to evaluate water absorption in bamboo fiber composites. Bamboo is hydrophilic, means that it easily absorbs water. In this study the bamboo fiber-based composites were developed using hand lay up method, with epoxy resin as the matrix constituent. Water absorption characteristics of specimens of bamboo composite and epoxy were determined from water immersion tests at several temperatures. Gravimetric analysis was performed to determine the moisure absorbed as a function of time at two different temperatures: 25 ºC and 50 C. The diffusivity of water in an epoxy bamboo composite was determined after reaching saturation point. During room temperature soaking, epoxy specimen showed the characteristic of Fickian behavior. Similar immersion tests on bamboo-epoxy composites followed nonfickian behavior. Changes in the mechanical properties of material due to water absorption were evaluated from tensile testing on materials with varied water content. It was found that the waterabsorption in all samples reduced the tensile properties. The degradation of tensile properties was greater with an increasing temperature of immersion. The results of this study emphasize the importance ofconsidering deterioration of mechanical properties in the bamboo epoxy composites during their application in water and possibly in humid environment.

Published: November 2019

This study presents the first comprehensive investigation of population aspects and ecological traits of water beetles in oligotrophic hydrosystems with tufa formation in southeastern Europe. Diverse lotic habitats (springs, rivers and tufa barriers) were investigated monthly for one year in Plitvice Lakes National Park in Croatia. Elmidae were the most diverse and abundant family, followed by Scirtidae and Hydraenidae. The ecological traits of water beetles were primarily defined by nutrients and water depth.Elmis bosnicaZaitzev, 1908, about which little has been published, was found to be bryophilous and to prefer low water temperatures. Biogeographical analysis revealed the dominance of typical southeastern and Mediterranean species. Species population dynamics could be attributed to differences in flow permanence, current velocity and canopy coverage. Both current velocity and water depth significantly influenced the occurrence of larval stages, while abundance of adults correlated with water depth. Our results highlight tufa barriers as preferred habitats for species of the genusRiolusand the family Scirtidae. The results of this study, many of which are the first to be reported for water beetles, provide a basis for further investigations of these animals and their ecology in oligotrophic hydrosystems with tufa. In particular, our study demonstrates the potential of Elmidae as water quality indicators, which should be considered in future conservation and protection management efforts.
Construction and analysis of fourth order, energy consistent, family of explicit time discretizations for dissipative linear wave equations
Authors: Chabassier Juliette , Diaz Julien , Imperiale Sébastien
Published: November 2019

This paper deals with the construction of a family of fourth order, energy consistent, explicit time discretizations for dissipative linear wave equations. The schemes are obtained by replacing the inversion of a matrix, that comes naturally after using the technique of the Modified Equation on the second order Leap Frog scheme applied to dissipative linear wave equations, by explicit approximations of its inverse. The stability of the schemes are studied using an energy analysis and a convergence analysis is carried out. Numerical results in 1D illustrate the space/time convergence properties of the schemes and their efficiency is compared to more classical time discretizations.

Published: November 2019

Hintergrund Opioidabhängige sind häufig von psychischen Komorbiditäten, insbesondere affektiven Störungen wie Depressionen betroffen. Die Diagnostik und Behandlung von depressiven Störungen in der Substitutionsbehandlung Opioidabhängiger stellen eine besondere Herausforderung dar. Dabei besteht die Gefahr, dass ein Teil der Patienten mit depressiven Symptomen unterversorgt bleibt.

Ziel Die Studie untersucht das Ausmaß depressiver Symptome bei opioidabhängigen Patienten in einer Substitutionsbehandlung und prüft die Übereinstimmung von Selbst- und Fremdbeurteilungen durch den Patienten und den jeweiligen substituierenden Arzt.

Methoden Zeitgleiche Fragebogenerhebung in 6 substituierenden Einrichtungen in Hamburg, Bremen und Kassel. Die Selbstbeurteilung zum Ausmaß von depressiven Symptomen erfolgte bei den Patienten mittels Beck Depressionsinventar (BDI-II). Zeitgleich wurden die substituierenden Ärzte anhand der Hamilton Depressions-Skala (HAMD) zur Beurteilung der depressiven Symptombelastung ihrer Patienten befragt.

Ergebnisse Opioidabhängige Patienten in Substitutionstherapie sind häufig in einem klinisch relevanten Ausmaß von depressiven Symptomen betroffen. Es konnte ein positiver Zusammenhang zwischen den Instrumenten in 4 kategorialen Ausprägungen bestätigt werden. Im Vergleich zur Selbstbeurteilung schätzten die Ärzte die depressive Belastung ihrer Patienten als weniger schwer ein.

Schlussfolgerung Die beiden verwendeten Instrumente sind geeignet, die Diagnostik von depressiven Symptomen bei Opioidabhängigen in Substitutionstherapie zu unterstützen, wobei die Fremdbeurteilung durch die substituierenden Ärzte zurückhaltender ausfällt. Die Studienergebnisse verweisen auf die hohe Relevanz der Diagnostik depressiver Symptomatik unter Opioid-Substituierten, um ggf. geeignete Behandlungsmaßnahmen einzuleiten.

Published: November 2019

A new computationally assisted diagnostic to measure NO densities in atmospheric-pressure microplasmas by Optical Emission Spectroscopy (OES) is developed and validated against absorption spectroscopy in a volume Dielectric Barrier Discharge (DBD). The OES method is then applied to a twin surface DBD operated in N2 to measure the NO density as a function of the O2 admixture (0.1%–1%). The underlying rate equation model reveals that NO(A2Σ+) is primarily excited by reactions of the ground state NO(X2Π) with metastables N2(A3Σu+).
Nanosecond transient thermoreflectance method for characterizing anisotropic thermal conductivity
Authors: Yuan Chao , Waller William M. , Kuball Martin
Published: November 2019

A method is presented to characterize the anisotropic thermal properties of materials based on nanosecond transient thermoreflectance (TTR). An analytical heat transfer model is derived for the TTR signal, showing that the signal is sensitive to out-of-plane and in-plane heat conductions at distinct time scales. This sensitivity feature can be exploited to simultaneously determine the out-of-plane and in-plane thermal conductivities. Examples are given for molybdenum disulphide, hexagonal boron nitride, and highly oriented pyrolytic graphite to assess the validity of this method.
Transient characteristics of back-gated multilayer MoS2 and WSe2 channel n-type metal oxide semiconductor field effect transistors: A comparative study
Authors: Shen Hui , Bu Sitong , Huang Daming
Published: November 2019

The surface and interface effects of back-gated transition metal dichalcogenide channel MOSFETs are of great importance to device applications. This paper reports the transient current-time (I-t) characteristics of back-gated multilayer MoS2 and WSe2 channel n-type MOSFETs due to the charge trapping into the surface and interface traps of the devices. By investigating the current-voltage and I-t results measured from the devices with a similar structure and bias conditions under ambient and vacuum conditions, we find that the WSe2 devices show more significant surface and interface effects as compared to the MoS2 devices. The comparison of the experimental results with the technology computer aided design simulation shows that a single type trap model can account for the main characteristics of the transient process observed from the MoS2 and WSe2 devices. As compared to the trap on the MoS2 device, the surface trap on the WSe2 device has higher density, lower energy, and smaller trapping time. A further experimental comparison with WS2 devices suggests that the difference is microscopically originated from the chalcogen of Se and S rather than the metal element of Mo and W.

Authors: Qi Yuxuan , Li Wei , Liu Suping , Ma Xiaoyu
Published: November 2019

An optimization method for an arrangement of vertical cavity surface emitting laser (VCSEL) arrays to improve thermal characteristics of the arrays is presented. The method is based on the principle of minimum potential energy and is implemented by a self-organizing algorithm. The thermal and electrical properties of the active regions of the unoptimized and optimized arrays were obtained by a self-consistent thermoelectric simulation of the VCSEL structure based on the finite element method. The output characteristics of the unoptimized and optimized 4 × 4 square VCSEL arrays were studied theoretically and practically. The results showed that the optimized arrays have improved thermal characteristics.
Electron-impact ionization cross sections of new SF6 replacements: A method of combining Binary-Encounter-Bethe (BEB) and Deutsch-Märk (DM) formalism
Authors: Zhong Linlin , Xu Jie , Wang Xiaohua , Rong Mingzhe
Published: November 2019

Recently, much attention has been paid to some new carbon-fluoride gases, such as C2F4H2 (R134), C3F4H2 (HFO1234ze), C4F8, C4F7N, C5F10O, and C6F12O. All these gases present excellent dielectric strength and very low values of global warming potential and thus have potential to replace sulfur hexafluoride (SF6) as an insulating medium. However, the electron-impact ionization cross sections (Qion), which are the necessary basic data for the investigation of plasma discharges in these gases, are still unavailable. This work is devoted to the calculation of Qion for the above new SF6 replacements with incident electron energy of up to 5000 eV. We propose a method of combining the Deutsch-Märk (DM) formalism at low electron energy and the Binary-Encounter-Bethe (BEB) formalism at high electron energy by using a dual sigmoid function. The comparison between the calculated and experimental Qion for various molecules indicates that this new combined method yields 49.41% and 61.24% improvement by the Euclidean metric on average compared with the BEB and DM methods, respectively. We also investigate the effects of molecular orbitals and atomic shells on the Qion of new SF6 replacements. It is found that the BEB method conforms to the law that higher molecular orbitals have larger effect on electron-impact ionization of a molecule, while the DM method does not. Generally, the 2p shells of carbon, nitrogen, or oxygen atoms in a molecule play a dominant role in electron-impact ionization, whereas the shells of fluorine atoms do not affect the ionization process very significantly.

Published: November 2019

Insulator-based dielectrophoresis (iDEP) has become a powerful tool for biomicrofluidic separation and analysis because it is capable to selectively separate biological particle systems according to properties like size, material, and shape. However, it has rarely been used to solve challenging separation problems involving nonbiological particles, namely, for systems that are prone to particle agglomeration. Here, we demonstrate material-selective separation of nonbiological systems, i.e., polystyrene and gold-coated polystyrene particles of two different sizes, using iDEP at high accuracy. For this purpose, we present a method to generate fluorescent gold-coated particles. We further introduce a method to reduce the static backpressure that builds up between in- and outlet reservoir due to electroosmotic flow. Moreover, we found that particle agglomeration makes their separation impossible when conventional iDEP routines are applied. Therefore, two solutions to reduce particle agglomeration are presented: A combination of AC and DC potentials and adjustment of pH and conductivity of the suspending medium. Both approaches allow separating particles under challenging conditions such as initially low absolute particle zeta potentials and high particle concentrations. Since those conditions can also be present in biological iDEP separation processes, the results are of general value for biological and nonbiological iDEP operations.
Statistical behaviors of conditioned two-point second-order structure functions in turbulent premixed flames in different combustion regimes
Authors: Brearley Peter , Ahmed Umair , Chakraborty Nilanjan , Lipatnikov Andrei
Published: November 2019

The second-order structure functions and their components conditioned upon various events have been analyzed for unweighted and density-weighted velocities using a Direct Numerical Simulation database. The heat release due to combustion has been shown to have significant influences on the structure functions and their components conditioned on different mixture states. The use of density-weighted velocities changes the relative magnitudes of differently conditioned structure functions but does not reduce the scatter of these magnitudes. The structure functions conditioned to constant-density unburned reactants at both points and normalized using the root-mean-square velocity conditioned to the reactants are larger at higher values of mean reaction progress variables c¯ (deeper within the flame brush), with this trend being not weakened with increasing turbulence intensity u′/SL. These results indicate that, contrary to a common belief, combustion-induced thermal expansion can significantly affect the incoming constant-density turbulent flow of unburned reactants even at u′/SL and Karlovitz number Ka as large as 10 and 18, respectively. The statistical behaviors of the structure functions reveal that the magnitude of the flame normal gradient of the velocity component tangential to the local flame can be significant, and it increases with increasing turbulence intensity. Moreover, the structure functions conditioned on both points in the heat release zone bear the signature of the anisotropic effects induced by the baroclinic torque for the flames belonging to the wrinkled flamelet and corrugated flamelet regimes. These anisotropic effects weaken with increasing turbulence intensity in the thin reaction zone regime.
First-principles study of antisite defects in perovskite stannates
Authors: KC S. , Rowberg A. J. E. , Weston L. , Van de Walle C. G.
Published: November 2019

The perovskite stannates BaSnO3 and SrSnO3 are being actively explored for applications as transparent conductors, in power or high-frequency electronics, and as channel materials in epitaxial integration with functional perovskites. Realizing these applications requires controlled n-type doping, i.e., avoiding the formation of compensating acceptor-type defects. Here, we use density-functional theory to examine the formation of cation antisite defects. Our results indicate that antisites are not a problem in BaSnO3; however, in SrSnO3, SrSn antisites may act as compensating centers.
Cluster ion source for external injection and high capacity filling of light elements into the relativistic heavy ion collider electron beam ion source
Authors: Kondrashev S. , Beebe E. , Okamura M.
Published: November 2019

An advanced Electron Beam Ion Source (EBIS) is the primary ion source to supply highly charged ion beams of different elements to the Relativistic Heavy Ion Collider (RHIC) and to the NASA Space Radiation Laboratory (NSRL). Intense beams of highly charged ions of various elements of the periodic table, ranging from helium to uranium, have been demonstrated since EBIS became operational in 2010. EBIS routinely provides ion beams to RHIC and NSRL quasisimultaneously with about 1 s switching time between different ion species. Such unique flexibility and rapid switching between ion species are based on external injection of singly charged ions into the EBIS trap either in “fast” or “slow” injection modes. At present, a Laser Ion Source (LIS) provides most of the ion species of solid materials using the “fast” injection mode into the EBIS trap and a Hollow Cathode Ion Source (HCIS) provides most of the ion species of gaseous elements using the “slow” injection mode into the EBIS trap. Gas injection into the EBIS trap is also possible and has been used but imposes some restrictions for the simultaneous generation of highly charged ions such as Au32+ ions for RHIC and ions of gaseous species for NSRL. Because light ions have relatively high velocity inside the EBIS trap, efficient injection of hydrogen and helium ions and filling of the EBIS trap to high capacity is difficult from either LIS or HCIS. To overcome this restriction and enhance EBIS operational capability, we suggest injecting beams of hydrogen and helium cluster ions into the EBIS trap. Required parameters of cluster ion beam injection into the EBIS trap are estimated, and advantages of such an injection are highlighted. A cluster ion source with required high intensity is visible and will be designed, built, optimized, and tested.
Anharmonicity of Bi2Se3 revealed by fs transient optical spectroscopy
Authors: Liu Qiya , Shao Ruihui , Li Ning , Liang Weizheng , Yang Xinsheng , Luo S. N. , Zhao Yong
Published: November 2019

We investigate the anharmonic effects in Bi2Se3 crystals using femtosecond transient optical spectroscopy at 5–280 K. The reflectivity time series consist of exponential decay due to hot carriers and decaying oscillations due to the A1g1 phonon vibration. Vibration frequency and dephasing time of this optical phonon mode are obtained as a function of temperature, decreasing with increasing temperature; both the red shift in frequency and the increased dephasing rate induced by heating can be well described using the anharmonicity model including lattice thermal expansion and phonon-phonon coupling.

Published: November 2019

Although millions of transcription factor binding sites, or cistromes, have been identified across the human genome, defining which of these sites is functional in a given condition remains challenging. Using CRISPR/Cas9 knockout screens and gene essentiality or fitness as the readout, we systematically investigated the essentiality of over 10,000 FOXA1 and CTCF binding sites in breast and prostate cancer cells. We found that essential FOXA1 binding sites act as enhancers to orchestrate the expression of nearby essential genes through the binding of lineage-specific transcription factors. In contrast, CRISPR screens of the CTCF cistrome revealed 2 classes of essential binding sites. The first class of essential CTCF binding sites act like FOXA1 sites as enhancers to regulate the expression of nearby essential genes, while a second class of essential CTCF binding sites was identified at topologically associated domain (TAD) boundaries and display distinct characteristics. Using regression methods trained on our screening data and public epigenetic profiles, we developed a model to predict essential
cis
-elements with high accuracy. The model for FOXA1 essentiality correctly predicts noncoding variants associated with cancer risk and progression. Taken together, CRISPR screens of
cis
-regulatory elements can define the essential cistrome of a given factor and can inform the development of predictive models of cistrome function.

Brain infection by the parasiteToxoplasma gondiiin mice is thought to generate vulnerability to predation by mechanisms that remain elusive. Monocytes play a key role in host defense and inflammation and are critical for controllingT. gondii. However, the dynamic and regional relationship between brain-infiltrating monocytes and parasites is unknown. We report the mobilization of inflammatory (CCR2+Ly6Chi) and patrolling (CX3CR1+Ly6Clo) monocytes into the blood and brain duringT. gondiiinfection of C57BL/6J and CCR2RFP/+CX3CR1GFP/+mice. Longitudinal analysis of mice using 2-photon intravital imaging of the brain through cranial windows revealed that CCR2-RFP monocytes were recruited to the blood–brain barrier (BBB) within 2 wk ofT. gondiiinfection, exhibited distinct rolling and crawling behavior, and accumulated within the vessel lumen before entering the parenchyma. Optical clearing of intactT. gondii-infected brains using iDISCO+and light-sheet microscopy enabled global 3D detection of monocytes. Clusters ofT. gondiiand individual monocytes across the brain were identified using an automated cell segmentation pipeline, and monocytes were found to be significantly correlated with sites ofT. gondiiclusters. Computational alignment of brains to the Allen annotated reference atlas [E. S. Lein et al.,Nature445:168–176 (2007)] indicated a consistent pattern of monocyte infiltration duringT. gondiiinfection to the olfactory tubercle, in contrast to LPS treatment of mice, which resulted in a diffuse distribution of monocytes across multiple brain regions. These data provide insights into the dynamics of monocyte recruitment to the BBB and the highly regionalized localization of monocytes in the brain duringT. gondiiCNS infection.
The conceptual spatialization of actions or activities in Chinese
Authors: Wang Wenbin
Published: November 2019

This chapter focuses on the semantics of a grammatical pattern in Chinese that combines an adjective with a verb (Adj + V construction). The pattern contravenes the grammatical traditions, which assume that a noun is typically modified by an adjective (Adj + N) and a verb by an adverbial (Adv + V). This study shows that the Adj + V construction is not only pervasive in Chinese, but that the V may even convey a highly dynamic meaning. Rather than concluding that the existence of the construction is the evidence of a word class shift from verb to noun, from a cognitive perspective, it is argued that the Adj + V construction mirrors a certain way of thinking about actions and activities in terms of entities and substances located in space.
The role of metaphor in categorization
Authors: Gong Yumiao , Zhou Rong
Published: November 2019

This study is concerned with the processing of metaphor in real time for the purpose of elucidating metaphor categorization. We distinguish between attributive metaphors such as the surface of the lake is a mirror, in which the attributes of a lake are likened to those of a mirror, and conceptually complex relational metaphors like history is a mirror, which exhibit a structural resemblance between the topic history and the metaphorical vehicle mirror. We conducted an experiment that provided evidence that for attributive metaphors only literal meanings of the vehicle are activated, while in relational metaphors they are activated only for 300 ms, but then actively suppressed. Our experimental data suggest that, for relational metaphors, structure-mapping and schema induction underlie metaphorical categorization.
Linguistic and mental representations of caused motion in Chinese and English children
Authors: Ji Yinglin
Published: November 2019

This study examines (non)linguistic representations of caused motion by Chinese and English children in two cartoon-based experiments. Findings of the language production task reveal that typological properties influence the semantic density of children’s utterances. Regardless of age, children express denser semantic information in Chinese than in English. In the non-linguistic match-to-sample task, children of 3 years are found to be predominantly path-oriented, as evidenced by their significantly longer fixation on path-match (rather than manner-match) videos. The analysis of reaction time indicates that children of 8 years and adults show significant variations in spatial cognition that can be related to linguistic differences: English speakers tend to be more manner-oriented while Chinese speakers are equally manner- and path-oriented.
The role of social networks in cross-dialectal variation in the perception of the Rioplatense assibilated pre-palatal [ʃ]
Authors: Schmidt Lauren B.
Published: November 2019

This chapter presents a quantitative study of cross-dialectal differences in the perceptual categorization of the assibilated pre-palatal (e.g., calle ‘street’ /kaʃe/), a feature of Rioplatense Argentine Spanish. Listeners from two South American varieties of Spanish that varied in degree of contact with Rioplatense speakers completed an Identification Task in which they categorized [ʃ] in Spanish pseudowords. Results revealed that listeners from the contact group (La Rioja, Argentina) identified the phone as the intended phonetic category, orthographic , while listeners with limited contact with Rioplatense Spanish (Bogota, Colombia) assigned the phone to a separate category, orthographic . The study shows how contact with non-local speech varieties may result in changes to perceptual norms, even in the absence of use (production) of these forms.
The social perception of intervocalic /k/ voicing in Chilean Spanish
Authors: Bolyanatz Brown Mariška A. , Rogers Brandon M. A.
Published: November 2019

In this study, we investigate what social meaning is attributed to a nascent change in progress in Chilean Spanish, examining whether intervocalic voicing of the phonologically voiceless stop /k/ affects listener judgments along several perceptual scales. Eight brief excerpts of spontaneous speech were digitally manipulated to vary only in voicing in tokens of /k/, and thirty listeners responded via an online experiment. We find that listeners are not sensitive to voicing along three of the measured scales and are not sensitive to voicing at all in female speech. We also determined that listeners are only sensitive to intervocalic voicing when assigning values of Chilean identity to male speakers, and that this effect is mitigated by headphone use. Some of listeners’ insensitivity matches previous production data in this dialect, while we expected some sensitivity along other measures but found none. We posit that this mismatch is due to the salience of the variable: because listeners may be unfamiliar with intervocalic voicing of /k/, they have not yet indexed voicing of intervocalic /k/ with particular speaker features, aligning with Campbell-Kibler (2009).
Future directions for sociophonetic research in Spanish
Authors: Henriksen Nicholas
Published: November 2019

This epilogue offers a brief overview of the eleven chapters included in this volume, calls attention to effective commonalities amongst the studies, and highlights innovative strategies for future sociophonetic research. The methodologies applied by the authors are discussed in relation to their work, which includes but is not limited to consonantal, vocalic, and regional variation in Spanish. Of these, special attention is paid to incorporating future work on vowel contrasts and prosody, with an in-depth discussion of potential implications. These topics are then re-integrated with the rest of the epilogue in order to offer insights into new avenues of theoretical interest, such as listener-based models of language change. A closer melding of data from production (articulation and acoustics) and from the perception of individual speakers presents a particularly fruitful direction for future research. Altogether, the works included in this volume lay the foundation for a promising future in the area of Spanish sociophonetic perception.
A Criterial Approach to the Cartography of V2
Authors: Samo Giuseppe
Published: November 2019

This volume provides a mechanism to uncover the extremely rich split-CP of V2 languages, in both root and embedded clauses, on the basis of theoretical arguments and empirical findings. The movement of the inflected verbal head is triggered to agree with the profiled informational value of the fronted XP. The V2 “constraint” shall thus be observed as a sum of micro-V2s, in which the inflected head creates Spec-Head configurations with the activated criterial positions in the relevant context. The “second linear” position of the verb results from the movement of the inflected verb to the highest activated criterial head. In other words, there is no “bottleneck effect”, but ordinary violations in terms of locality between fronted XPs. This monograph is aimed principally at postgraduate students and researchers interested in the description of natural languages adopting the guidelines of the Cartography of Syntactic Structures.
Aquaculture occupational safety and health in Brazil.
Authors: Cavalli L. S. , Marques F. B. , Watterson A.
Published: November 2019

Health, safety and injury prevention actions should be prioritized in aquaculture, where workers are exposed to a wide range of risks. This paper is based on a scoping report by a group of international experts, funded by the Food and Agriculture Organization (FAO) and administered by Fisheries and Aquaculture Workers Network of the International Union of Food, Agricultural, Hotel, Restaurant, Catering, Tobacco and Allied Workers' Associations (IUF). Relevant literature was reviewed and the study drew on an international workshop to develop templates and related for regional and national aquaculture occupational safety and health (AOSH) profiles. The literature review included Scielo and Google Scholar databases as well as Google and Brazilian government websites. The searches included material in Portuguese, English and Spanish. The results reported here give an overview of Brazilian AOSH and hazards and cover Brazilian and relevant international worker health and safety laws and organization applicable to the particular hazards in aquaculture. There is a special emphasis on the position of children and women workers linked to the wider social organization of work and welfare, and finally the challenges to and possibilities for good AOSH. Despite major developments in aquaculture production, much still needs to be improved to ensure the safety and health of workers in the sector.

Published: November 2019

This study aimed to determine the optimal accelerometer wear‐site specific cut‐points for discrimination of the sedentary time, light physical activity and moderate‐to‐vigorous physical activity (MVPA) in older adults. Twenty‐three adults (14 females) aged 55–77 years wore a GENEActiv accelerometer on their non‐dominant wrist, dominant wrist, waist and dominant ankle whilst undertaking eight, five‐minute bouts of activity: lay supine, seated reading, slow walking, medium walking, fast walking, folding laundry, sweeping and stationary cycling. VO2 was assessed concurrently using indirect calorimetry. Receiver‐operating‐characteristic (ROC) analyses were used to derive wear‐site specific cut‐points for classifying intensity. Indirect calorimetry indicated that being lay supine and seated reading were classified as sedentary (<1.5 METs), laundry as light (1.51–2.99 METs) and sweeping, slow, medium and fast walking and cycling all classified as moderate intensity (>3 METs). Areas under ROC curves indicated that the classification of sedentary activity was good for the non‐dominant wrist and excellent for all other wear sites. Classification of MVPA was excellent for the waist and ankle, good for the waist and poor for the dominant and non‐dominant wrists. Overall, the ankle location performed better than in other locations. Ankle‐worn accelerometry appears to provide the most suitable wear‐site to discriminate between sedentary time and MVPA in older adults.

The Full-disk MagnetoGraph (FMG), a payload onboard the Advanced Space Solar Observatory (ASO-S), will measure the vector magnetic field in the photosphere. The instrument consists of a front-window filter, a telescope, an LCVR polarimeter, an image-stabilization system, a seven-stage tunable Lyot filter, a CMOS camera with 4096×4096 pixels and a pair of calibration/focus wheels. In this paper, we describe the design of the FMG instrument and provide a summary of test observations carried out with the FMG prototype.

Authors: Vial Jean-Claude
Published: November 2019

This paper addresses the improved science resulting from joint observations performed by the different instruments onboard the Advanced Space-based Solar Observatory (ASO-S) mission along with ancillary instruments on missions flying at the same time. It first describes the three major instruments along with their stated objectives. Then it presents some basic science issues concerning jointly observed flares, coronal mass ejections (CMEs) and eruptive prominences (EPs). Each physical candidate (magnetic reconnection, instability, hard X-ray emission and magnetic coronal field topology) is discussed in terms of its signature and identification with ASO-S instrumentation. The importance of Lyα detection and non-LTE modeling is stressed. Some instrumental and science challenges are briefly discussed.

Authors: Mazaya H S , Supriyanto
Published: November 2019

In the area presence of remnants of a historical Speelwijk castle friary built in 1681 – 1684 and in 1780 the inside building ruined. It different if we see from map Speelwijk castle around earlier years when the inside of the building is still there. To see the traces of the building we used geophysical methods i.e GPR. GPR survey using mostly a 600 MHz frequency antenna to get high-resolution and low penetration. GPR works by sending a tiny pulse of energy into a material via antenna. Subsurface variations create reflections that are picked up by the material content. GPR can provide high resolution imaging of shallow subsurface targets based on changes in the electromagnetic properties of the material. The visualization data GPR will image two dimensional (2D) where we can see the depth from anomalies body. The 2D view allows the enhanced targets to an identification of potential archaeological object buried.

Mach Zehnder interferometer (MZI) based on plastic optical fiber (POF) is interesting due to its robustness and simple fabrication. In this work, MZI-POF was designed and its sensitivity to temperature change was characterized to investigate its performance for sensor application. The MZI-POF was fabricated by forming two tapers at several distance by simple heat-pull method. The spectra was investigated by launching white light emitting diode (LED) and the output were observed using VIS-NIR spectrometer. It is shown that the wavelength of spectrum peak and spectrum dip were shifted compared to that of un-tapered POF which indicates that the structure serves well as MZI. Sensor sensitivity to temperature was determined by measuring the spectrum for various temperature which was varied from 40°C to 80°C with increment of 5°C. The result showed that the sensor sensitivity is 0.0693nm/°C in terms of peak measurement and 0.0487nm/°C for dip measurement. Therefore, MZI-POF is a potential candidate for temperature sensor.
The effect of pH on the characteristics of the methyl red solution as a gamma-ray dosimeter
Authors: Chairunisa W , Imawan C
Published: November 2019

The effect of the pH on the color change characteristics of the methyl red solution, when exposed by gamma radiation, is the main objective of this study. The colorwas characterized using a UV-Visible spectrophotometer and a digital photography camera. The used irradiator source is 60Co with doses varied from 5-100 kGy and a dose rate of 5.5 kGy/h. The color stability was studied by observing the effects of the storage conditions of the solution: temperature, light, and humidity. The original methyl red solution at pH 6.3 has a red color and gives a radiochromic phenomenon with a change of color from red to dark red for a dose of 5-20 kGy, then the color fades and turns colorless gradually at a dose of 25-100 kGy. On the other hand, for a methyl red solution of pH 7.1 before irradiation has a yellow color, turns to dark yellow at doses of 5-25 kGy, then the color fades and becomes colorless at a dose 40 kGy. The color of the methyl red solution at pH 7.1 is more stable against storage light conditions compared to pH 6.3. These results suggest that this methyl red solution can be used as a gamma-ray dosimeter in the dose range of 5-40 kGy.

Published: November 2019

We have investigated the influence of strong magnetic fields at the center of the quark stars which is an impact to shape of stars by using Einstein’s theory of gravity, which uses the EoS CIDDM model. Our focus in this study is to compare the results of the deformation degree of quark stars from theory of gravity Einstein and Rastall, where on Rastall gravity introduced degree of freedom λ, where we use variations of λ = 1, 2, 3, 4 and 5, where Rastall gravity will reduced to Einstein theory of gravity at the value of λ = 1. We obtained for each EoS with different values of κ
1 indicate the degree of deformation tends toward prolate at the maximum mass of the same quark star for the both theories, the most significant difference on Rastall gravity is the maximum mass of quark stars increases with the high value of the λ we set.
