Published: May 2020

The purpose of this research is to analyze the possibility of implementing Smart Urban Railway Space concept in the development of Semarang Tawang Station area which is one of the entrance gates of Semarang tourists and has a high historical value. The area of Tawang station becomes an integral part of Semarang Old Town because of its adjacent location. This attachment is one potential that can be considered to grow the activity of the area into a tourism area and a business center. Increasing number of visitors can cause overcrowding. The crowded situation of visitors caused the lack of circulation so that the need for redesigning Tawang station area. A station area (public transportation) must be able to adapt to the environment and function needs for the visitor. Smart city design is about rethinking infrastructure, buildings and facilities as well as other infrastructure integrated to form smart cities and smart urban space.  Smart Urban railway space is a concept that integrates an architectural building with the surrounding open space. It is hoped that this concept can parse overcrowding and make the area of Tawang station a tourism area. Methods used are qualitative methods with a rationalistic approach. The result of this research is a recommendation of the Smart Urban Railway Space concept at Tawang station area which is expected to parse the overcrowding problem that occurred.

Published: May 2020

microRNAs (miRs) are fundamental regulators of protein coding genes. In the CNS, miR-9 is highly enriched and critical for neuronal development and function. Mature miRs are derived from a duplex precursor, and the -5p strand (“guide”) is preferentially incorporated into an RNA-induced silencing complex (RISC) to exert its regulatory functions, while the complementary -3p strand (“passenger”) is thought to be rapidly degraded. By contrast, both strands of the miR-9 duplex have unique functions critical for neuronal physiology, yet their respective degradation rates and mechanisms governing degradation are not well understood. Therefore, we determined the degradation kinetics of miR-9-5p and miR-9-3p and investigated thecisandtranselements that affected their stability in the brain. Using a combination of homogeneous neuronal/astrocyte cell models and heterogeneous brain tissue lysate, we demonstrate the novel finding that miR-9-3p was more stable than the miR-9-5p guide strand in all models tested. Moreover, the degradation kinetics of both miR-9-5p and miR-9-3p were brain-region specific, suggesting that each brain region was differentially enriched for specific degradation factors. We also determined that the 3′ nucleotides harbor importantciselements required to not only maintain stability, but also to recruit potential protein degradation factors. We used mass spectrometry to assess the miR-9 interacting proteins and found that the -5p and -3p strands were associated with functionally distinct proteins. Overall, these studies revealed unique miR-9-5p and miR-9-3p degradation kinetics in the brain and proposed critical nucleotide sequences and protein partners that could contribute to this differential stability.

Authors: Wu Qin , Xing Yuhan , Shi Lei , Li Wenjie , Gao Yang , Pan Silin , Wang Ying , Wang Wendi , Xing Quansheng
Published: May 2020

BACKGROUND AND OBJECTIVES:

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a newly identified pathogen that mainly spreads by droplets. Most published studies have been focused on adult patients with coronavirus disease 2019 (COVID-19), but data concerning pediatric patients are limited. In this study, we aimed to determine epidemiological characteristics and clinical features of pediatric patients with COVID-19.

METHODS:

We reviewed and analyzed data on pediatric patients with laboratory-confirmed COVID-19, including basic information, epidemiological history, clinical manifestations, laboratory and radiologic findings, treatment, outcome, and follow-up results.

RESULTS:

A total of 74 pediatric patients with COVID-19 were included in this study. Of the 68 case patients whose epidemiological data were complete, 65 (65 of 68; 95.59%) were household contacts of adults. Cough (32.43%) and fever (27.03%) were the predominant symptoms of 44 (59.46%) symptomatic patients at onset of the illness. Abnormalities in leukocyte count were found in 23 (31.08%) children, and 10 (13.51%) children presented with abnormal lymphocyte count. Of the 34 (45.95%) patients who had nucleic acid testing results for common respiratory pathogens, 19 (51.35%) showed coinfection with other pathogens other than SARS-CoV-2. Ten (13.51%) children had real-time reverse transcription polymerase chain reaction analysis for fecal specimens, and 8 of them showed prolonged existence of SARS-CoV-2 RNA.

CONCLUSIONS:

Pediatric patients with COVID-19 presented with distinct epidemiological, clinical, and radiologic characteristics from adult patients. Nearly one-half of the infected children had coinfection with other common respiratory pathogens. It is not uncommon for pediatric patients to have prolonged fecal shedding of SARS-CoV-2 RNA during the convalescent phase.

Published: May 2020

The aim of this research was to evaluate the effect of the Mentha spicata L. infusion on the performance and organoleptic characteristics of Cobb 500 broilers. The management, biosecurity and welfare of birds for open houses systems were followed, using a completely random design (CRD). Were used 200 1-day-old mixed chickens, in order to evaluate treatments effects during 35 days. Those were distributed in five treatments, with four réplicas, of 10 birds each to the following the groups: T1 (control), T2 (M. spicata infusion at 10%), T3 (M. spicata infusion at 20%), T4 (M. spicata infusion at 30%) and T5 (M. spicata infusion at 40%). The variables studied were broilers performance, carcass weight and organoleptic characteristics. The data was processed using with the statistical program Statgraphics Centurión XV.I, performing a multivariate analysis of variance and determining the factors with effect, and an ANOVA per week for the productive variables; contingency tables were prepared with organoleptic indicators data to determine differences (Chi-square test). Results show that the administration of M. spicata L. to drinkable water has no effect on broilers performance, with the exception of the feed intake, which decreases, reflecting a similar effect on visceral weight. The presence of flavonoids in the plant diminished the thickness of the abdominal fat because it favors the lipid metabolism of the birds. There was no difference in the smell of the meat, however, there were significant differences in the parameters of flavor, tenderness and juiciness.
Representation-based models in the current landscape of phonological theory
Authors: Bérces Katalin Balogné , Honeybone Patrick
Published: May 2020

Abstract

We place the healthy diversity of current (i.e., early 21st-century) phonological theory under scrutiny, and identify the four fundamental approaches that make it up: Rule-Based Phonology, Representation-Based Phonology, Constraint-Based Phonology, and Usage-Based Phonology. We then focus on the key aspects of and recent developments in Representation-Based Phonology: we separate out hybrid models and purely representational ones, we identify Government Phonology (GP) as the most popular form of the latter (and show that it is even present in what we call ‘GP-friendly’ analyses), and finally, we discuss and illustrate recent innovations in both subsegmental and prosodic structure in the two strands that we identify as ‘hyperhierarchical’ (or ‘vertical’) and ‘flat’ (or ‘horizontal’).

Published: May 2020

This article looks at what is referred to as the tense/lax contrast in English and proposes that members of the two sets of vowel have the same basic structure but differ in how part of that structure is made use of by its neighbours. The proposal forms part of a general theory of the representation of vowel height within the framework of Government Phonology 2.0.
The inflection of Tigre weak-final and strong verbs
Authors: Faust Noam
Published: May 2020

This paper provides a complete, exclusively phonological account of the alternations in the paradigms of the two largest verbal types in the Ethio-Semitic language Tigre. It is proposed that “weakfinal” verbs are constructed using the same templates and vocalizations as “strong” verbs. All of the differences between the two inflectional paradigms follow from weak-final verbs involving a vowel /e/ where strong verbs position a consonant. The analysis, conducted with the tools of Strict CV Phonology and Element Theory, is the first of its kind for Tigre.

The article showed the biodiversity and characteristic of Octocoral communities in Cu Lao Cham Marine Protected Area (MPA). A total of 165 samples were collected and identified as material of the Octocorals from 9 survey sites of Cu Lao Cham Marine Protected Area. The material represents 45 taxa belonging to 12 genera and seven families. Among them, Sinularia genus has the highest diversity with 19 species, Sarcophyton with 8 species and Lobophytum with 6 species. The other genera have one or two species. The diversity of Octocorals species in Cu Lao Cham Marine Protected Area is quite high after Nha Trang and Ly Son MPAs. Soft coral cover in Cu Lao Cham Marine Protected Area is the highest with average coverage 21.2% (±7.0 SE) compared with other MPAs of Vietnam. Distribution of Octocorals in Cu Lao Cham Marine Protected Area is mainly at 4–6 m (average coverage obtained 30%) and the cover decreases to the end of reef distribution. Our results showed that there are two distinguishing assemblages of Octocoral communities whose differences are the distribution characteristics, dominance of genera and species diversity.

The Simclast model has been verified and applied effectively in simulating the delta development for some major deltas in the world. In this study, we applied the model Simclast for simulating the history of the Red river delta development in late Pleistocene-Holocene. Results of the model reveal that the mainland of study area had reduced rapidly during transgression period (10,000-8,000 BP). The morphology changed significantly in the paleo-Red and Day river systems, but slightly in the paleo Thai Binh river system. The paleo-river network had been active in upper part before 11,000 BP and then shifted seaward until 2,000 BP. The river-sea interaction causes erosion and accumulation; as a result the morphology changed remarkably. The paleo-Thai Binh river had been inactive until 5,500 BP and then it was active but the morphology had not varied remarkably. The recent coastline generated from Simclast is relatively in accordance with the present coastline.

In order to keep essential depths in shipping channels to and from Hai Phong ports, regular dredging activities are maintained with about 3.6 million tons of sediments per year. Due to almost all the sediments of dredged material in the channels are composed of mud and silt, they are not easy to be used for land filling or other purposes. Moreover, disposing these materials on land is facing difficulties because of requiring the design and construction of dikes, requiring compaction and drainage of dumped materials. Therefore, disposal of dredged material from shipping channels in Hai Phong sea has become urgent. Based on integrated approach, the combination of numerical modeling and multicriteria decision analysis-GIS (natural condition, socio-economic and environment-ecosystem conditions) was made and the most suitable dumping sites were proposed in the regions with water depth ranging between 18–27 m. Their total receiving capacity was estimated about 206 million tons for 40–50 years.

In the context of global climate changes, mangroves are not only considered as an important ecological region but also as a source of exploitation of specific biological objects for researches and applications. In this study, mangrove-derived bacteria were isolated and screened for antimicrobial producers. Also, the strains with potential antibacterial activity were identified by 16S rRNA gene analysis. Results showed that 43% of 21 strains possessed antibacterial activity. The strain R10 showed inhibition against all four indicator bacteria and was identified as Bacillus pumilus with the highest sequence similarity of 100% to Bacillus pumilus NCTC10337 (GenBank accession number LT906438.1). The strain R7 inhibited Serratia marcescens causing severe “white spot” disease in reef building coral Acropora palmata and was closely related to Bacillus toyonesis BCT 7112 (GenBank accession number NR121761.1) with 99% sequence similarity. The strain R3 was the strongest strain against Bacillus subtilis compared with other strains which revealed the same antimicrobial activity pattern. The strain R3 was affiliated with Bacillus marisflavi TF-11 (GenBank accession number NR025240.1) with 98% sequence similarity and may be considered to represent new species. Moreover, the strain R9 inhibited only Gram negative tested strain and this strain was considered as a potential candidate for further search of antibiotics with spectrum of Gram negative bacteria.

Published: May 2020

Co To is an island of the Co To district in Quang Ninh province with an area of about 18 km2. Average rainfall on the island is 1,738.8 mm/yr, evaporation is 925 mm/yr. On the island, there are some small streams but they are temporary flow in the rainy season, there is not any natural lakes. There are 2 aquifers. The Quaternary aquifer (q) is distributed in a low terrain with area of about 9 km2, thin thickness and saline water is in about half of the area, so it does not make sense for water supply. The fissured aquifer of the ocdovic-silua (o-s) formation is distributed in the high terrain with an area of about 9 km2, this is low potential water layer. The flow rate in the boreholes in the fractured zone due to tectonic activity can be 1–1.5 l/s, it can satisfy small-scale water supply. Potential groundwater reserve of Co To island is 6,472 m3/day, exploitable reserve is 1941 m3/day, exploited reserve level at C1 range is 1,144 m3/day. This can satisfy the water demand for the living of people on the island today. Small-scale groundwater exploitation in the island has just been beginning, but it has the prospect of replication and at the same time there must be reasonable measures to protect and develop water resources to ensure sustainable development and meet the larger water requirements in the future.

A total of 356 species of 186 genera and 81 families of fishes were found in the waters of the Biosphere, in which some families were the most common including wrasses (Labridae: 42 species), damselfishes (Pomacentridae: 35), butterflyfishes (Chaetodontidae: 24), jack and travellies (Carangidae: 17), groupers (Serranidae: 14), surgeonfishes (Acanthuridae) and gobies (Gobiidae) with 11 species for each family, snappers (Lutjanidae: 10). The number of species in Cu Lao Cham waters (253 species) was 2.8 times higher than that in the Thu Bon estuary (91 species) and 4.2 times higher than that in transitional waters between the Thu Bon estuary and Cu Lao Cham (60 species). The coral reefs contributed 249 species and this was 8.6 times higher than that in the nipa palm (29 species), 6.5 times higher than in the seagrass beds (38 species) and 3.5 times higher than in the soft bottoms (71 species), however there were no significant differences between the nipa palm and the seagrass beds in the Thu Bon estuary. Among them, there were 10 valuable species of fishes found both in the Thu Bon estuary and Cu Lao Cham islands, and this indicates a high potential connectivity of these species among marine habitats in the two locations mentioned above.

The one-day-old O. latipes embryos is harvested and exposed to different concentrations of o, p`-DDT 0.04; 0.08; 0.12; 0.16; 0.2; 0.24; 0.28 and 0 µg/l (the control sample is not supplemented with o, p`-DDT) for 24, 48, 72 and 96 hours. After 24, 48, 72 and 96 hours, the results showed that LC50 value is gradually decreased, respectively 0.1013; 0.0772; 0.0486 and 0.0359 µg/l. The difference between LC50 values depends on the exposure concentration and exposure time. The results showed that the mortality rates of Medaka O. latipes increased with increasing pesticide concentrations as well as increasing exposure time. The experiment for observation of morphology and structure also found malformations in the spine and eyes of fish embryos. This chemical has strongly affected embryonic heart rate and embryonic morphology during growth and development.
Numerical model for simulation of waves in surfzone and nearshore areas based on Boussinesq equations: results for plane beaches
Authors: Hieu Phung Dang , Dung Le Duc , Khang Nguyen Thi
Published: May 2020

A numerical model based on the 2D Boussinesq equations has been developed using the Finite Volume Method. The model was verified against experimental data for the case of wave breaking on a sloping beach. Simulated results by the model showed that the model has good capability of simulation of waves in the nearshore area. Numerical simulation was also carried out for the problem of waves on a plane beach with a breakwater and submerged dunes. Simulated results were compared with those computed by MIKE 21. The comparison showed that good agreements were obtained and confirmed the applicability of the Boussinesq model to the simulation of physical phenomena of waves in the nearshore areas, especially, suitable for the simulation of wave-induced current including rip currents.

Published: May 2020

The Jinsha River rail–road double-deck arch bridge (bridge designed to 250 km/h) of the Chengdu–Guiyang high-speed railway (HSR) (designed to 350 km/h) is a complex system with a novel structure in China. The upper deck carries a four-track railway while the lower deck carries a six-lane urban expressway, with a height difference of 32 m. The bridge is located in the mountainous river reach of the city of Yibin. The 336 m main span adopts a high-pier, rigid steel frame, parallel tied-arch structure, built using cantilevers and temporary stay cables with the cable crane method. The 116 m and 120 m side-arches are reinforced concrete, simply-supported, basket-lifting tied-arches built by the mass cast in situ method. The rare layered structure gathers different arch types (top-bared, bottom-bared and half-through arches) into one bridge, which brought significant challenges to its design and construction. Other innovative solutions included flexible hangers passing through rigid hangers for the layered stiffening decks, ultra-high-performance concrete for the steel orthotropic deck road pavement and the use of boat shipments to overcome the scarce availability of flat land at the site. This paper describes some of the salient design and construction challenges of this landmark structure, the world's first double-deck HSR arch bridge.
Moral responsibility and action in the use of artificial intelligence in construction
Authors: McAleenan Philip
Published: May 2020

Rapid increases in processing power and speed of computing coupled with development of self-learning algorithms capable of autonomous decision making are central to current technological developments. This has fed dystopian visions of either out-of-control robots malevolently destroying humanity or benevolent robots enslaving humanity as a result of acting for its own good. A more nuanced assessment demonstrates that inherent in any benevolent intent is the unintended potential for harm, which must be addressed in parallel with if not in advance of developments in the field. This paper examines the hazards and challenges presented by artificial intelligence in respect of construction. In conjunction with developments and guidelines on machine ethics, it outlines the issues and posits how they may be addressed by governments, designers, contractors and worker organisations to access the growth potential of the sector as a socially responsible industry.
DISCIPLINARY LIABILITY FOR VIOLATION OF LEGAL ETHICS
Authors: Kukhnyuk D. , Shylenko B.
Published: May 2020

The article is devoted to the research of legal ethics and disciplinary liability of the lawyer for their violation, the necessity and expediency of such liability. It has been discovered that the legal community is a part of the modern Ukrainian society, which stands guard over the protection of its interests. The appropriate constitutional status and responsibilities imposed on the advocacy cause the society's acute attention to the moral and ethical component of the activity of the advocacy in general and each lawyer in particular. It concerns both daily activities in real life and legal activities in social networks, which have become a significant part of our reality due to their total dissemination in personal and professional life of the individual. Such increased public attention to advocacy determines the need to ensure appropriate quality control over the specified professional activity, which is carried out by specialized structural divisions of the advocacy as an autonomous and self-governing institute in Ukraine. The results of such control are the disciplinary liability of the lawyer. The definition of disciplinary liability of a lawyer is a special type of legal liability applicable to a lawyer based on the results of a disciplinary proceeding carried out by a qualification and disciplinary commission of the advocacy for committing a disciplinary offensce. The content of the Legal Ethics Rules has been researched and found to be rather extensive and contains only imperative obligations and prohibitions but does not contain specific guidance on the use of clearly defined sanctions for violation of a particular Rule. And the adherence of the lawyer to the Rules of Legal Ethics, the admissibility of their actions and statements in real life, as well as their activities in social networks are is determined on the basis of appraisal concepts and depends on the discretion of the authorities with the right of official interpretation of the Rules of Legal Ethics in the process of disciplinary proceedings and, as a result, disciplinarypenalties.

Authors: Arora V , Mulaveesala R , Dua G , Sharma A
Published: May 2020

Among various non-destructive testing and evaluation (NDT&E) methodologies, active infrared thermography (IRT) has emerged as a viable testing technique for the inspection of materials used in various industrial applications. In recent years, pulse compression favourable IRT techniques
and the associated post-processing schemes have been proposed by various research groups to enhance the inspection capabilities of existing conventional techniques, as well as to make experimentation simple and more reliable. This paper exploits a novel complementary coded thermal wave imaging
scheme for NDT&E applications, along with the associated data processing method, to enhance the test resolution and sensitivity. The proposed scheme has been numerically modelled on a metallic sample in order to test its capabilities for subsurface defect detection and characterisation.

This work presents the implementation of a high standards dataset of earthquake ground motions recorded in Metropolitan France between 1996 and 2016. This dataset is intended to serve the scopes of a large seismological community; however, its primary aims are engineering seismology and earthquake engineering applications. The dataset includes records from broadband and accelerometric sensors provided by permanent and temporary seismic networks operated by French research institutions and partners grouped within the Réseau Sismologique et géodésique Français (RESIF) consortium (see Data and Resources). All the waveforms are first homogenized to acceleration units and underwent a full quality control process including: (1) visual verification and manual phase picking, (2) processing scheme, and (3) consistency check by residual analysis. These make the dataset fully compliant with international standards. Finally, the RESIF dataset includes more than 6500 quality-checked records from 468 earthquakes recorded at 379 stations. Over the 379 stations included in the dataset, 177 are permanent stations (RA and FR networks) and 202 are temporary stations (YP and X7 networks). The dataset is complete down to magnitude ML 3.5 over the whole French territory and less (about ML 2.5) in the eastern part. Magnitudes range from ML 2.4 to 5.6 and from Mw 2.0 to 5.2, whereas distances range from less than 1 to 600 km. The disseminated dataset is constituted of (1) a versioned flatfile containing the metadata and main intensity measures computed on each processed record, (2) time histories, and (3) response spectra for several damping values and Fourier spectra.

Published: May 2020

Objectives: Vape shops have proliferated in the United States (US) in recent years. As of May 2016, the US Food and Drug Administration (FDA) asserted its authority to regulate electronic nicotine delivery systems. It is critical to understand how these polices have affected
the vape shop industry, as the rise and fall of vape shop proliferation has the potential for influencing public health. Methods: In this longitudinal study, we examined factors associated with vape shop (N = 77) closure over a 2-1/2-year period in southern California. We assessed predictors
of vape shops going out of business using a multivariate logistic regression model. Results: Among 77 vape shops assessed at baseline, 44.2% closed over a 2-1/2-year period. The absence of a "bar type" physical environment (OR = 2.64, 95% CI = 1.12-6.20), poorer shop accessibility (OR
= 7.11, 95% CI = 1.17-43.24), fewer reports of qualified personnel (OR = 2.28, 95% CI = 1.12-4.64), less average time spent in shop by customers (OR = 4.8, 95% CI = 1.18-19.60), a narrower e-liquid flavor selection (OR = 6.55, 95% CI = 1.56-27.49), and less vape device diversity (OR = 2.36,
95% C = 1.13-4.91) predicted vape shop closure. Conclusions: The rise and subsequent decline in vape shops could potentially affect public health. However, there needs to be more research on their association with public health..

Objectives: The addition of tiny rows of holes in the tipping paper (filter ventilation) of cigarettes allows air to mix with the smoke, which can change risk perceptions. In this study, we examine smokers' knowledge and beliefs about filter ventilation. Methods: Web-based
panel surveys conducted in 2016 and 2017 of current adult cigarette smokers (N = 2355) provided data on awareness and understanding of filter vents in their cigarettes, whether they believed blocking the holes would change the taste of their cigarettes, and their perceptions about their future
risk of being diagnosed with lung cancer. The most commonly used cigarette brands reported by participants also were characterized on the presence and level of ventilation holes. Results: Approximately 40% of participants (mostly younger and male) reported awareness of the filter ventilation
in their cigarettes. Only 30% of the participants were both aware of and understood the function of filter ventilation; they also were significantly more likely to worry about developing lung cancer. Conclusion: Although misleading descriptors associated with filter ventilation are
prohibited, most smokers still smoked cigarettes with filter vents, and many are unaware and misunderstand the potential risks of filter ventilation.

A perspectiva deste estudo é problematizar as falas de jovens alunos em sala de aula, quando colocamos em relevo seus comentários a respeito das abordagens por vezes pedagógicas e, em outras, orientadas por estratégias editoriais adotadas pelas revistas Atrevida e Todateen. Tencionamos questionamentos, quando afirmamos que os periódicos vão além de entreter e informar suas respectivas leitoras. Nesse sentido, afirmamos que os periódicos utilizam essas ferramentas quando pretendem “impor” e “vender” estilos e modos de ser adolescente em nossa sociedade contemporânea.
OCORRÊNCIA DE OCOS EM FUSTES DE INTERESSE COMERCIAL PROVENIENTES DE PLANOS DE MANEJO FLORESTAL SUSTENTÁVEL EM MADEIREIRAS DE RIO BRANCO, AC
Authors: Silva Correia Francisco Cildomar , Peruquetti Rui Carlos
Published: May 2020

O objetivo deste estudo foi observar a ocorrência de oco em fustes, de interesse comercial, proveniente de áreas de Planos de Manejo Florestal Sustentável – PMFS, em madeireiras de Rio Branco/Acre. Também verificar se as ocorrências desses fustes poderiam afetar o rendimento volumétrico de madeira, recebida pelas empresas estudadas. Além disso, procurou-se conhecer a que espécies botânicas pertenciam. O levantamento foi realizado em duas madeireiras, localizadas no Distrito Industrial, em Rio Branco/Acre. Ao todo, 2.544 fustes ocos foram observados. Os diâmetros dos fustes ocos variaram de 0,55m a 1,85m, enquanto o seu comprimento, de 2,5m a 8,6m. O volume das cavidades somou 366,5m3, na madeireira A e 547,5m3 na madeireira B. 7,61% da madeira recebida pelas duas empresas era representada por ocos, e pode ter causado prejuízo de US$58 por m3 a cada madeireira. Isso reforça a importância da exploração sustentável da floresta para manutenção da lucratividade das empresas madeireiras e a viabilidade dos PMFS. Além disso, constatou-se que Fabaceae apresentou maior número de espécies com presença de ocos, indicando que, possivelmente, trata-se de uma característica das espécies agrupadas nessa família.
