THE OSCILLATORY MECHANISMS ASSOCIATED WITH SYNTACTIC BINDING IN HEALTHY AGEING
Authors: Poulisse Charlotte , Wheeldon Linda , Limachya Rupali , Mazaheri Ali , Segaert Katrien
Published: June 2020

Older adults frequently display differential patterns of brain activity compared to young adults in the same task, alongside widespread neuroanatomical changes. Differing functional activity patterns in older adults are commonly interpreted as being compensatory (e.g., Cabeza, Locantore & McIntosh, 2002). We examined the oscillatory activity in the EEG during syntactic binding in young and older adults, as well as the relationship between oscillatory activity and behavioural performance on a syntactic judgement task within the older adults. 19 young and 41 older adults listened to two-word sentences that differentially load onto morpho-syntactic binding: correct syntactic binding (morpho-syntactically correct, e.g., “I dotch”); incorrect syntactic binding (morpho-syntactic agreement violation, e.g., “they dotches”) and no syntactic binding (minimizing morpho-syntactic binding, e.g., “dotches spuff”). Behavioural performance, assessed in a syntactic judgement task, was characterized by inter-individual variability especially in older adults, with accuracy ranging from 76-100% in young adults and 58-100% in older adults. Compared to young adults, older adults were slower, but not less accurate. Functional neural signatures for syntactic binding were assessed as the difference in oscillatory power between the correct- and no syntactic binding condition. In older adults, syntactic binding was associated with a smaller increase in theta (4-7 Hz), alpha (8-12 Hz) and beta (15-20 Hz) power in a time window surrounding the second word. There was a significant difference between the older and younger adults: in the alpha range, the condition difference seemed to be in the opposite direction for older versus young adults. Our findings thus suggest that the neural signature associated with syntactic binding in older adults is different from young adults. However, we found no evidence of a significant association between behavioural performance and the neural signatures of syntactic binding for older adults, which does not readily support the predictions of compensatory models of language and ageing.

Published: June 2020

Background: Stress and compromised parenting often place children at risk of abuse and neglect. Child maltreatment has generally been viewed as a highly individualistic problem by focusing on stressors and parenting behaviors that impact individual families. However, because of the global coronavirus disease 2019 (COVID-19), families across the world are experiencing a new range of stressors that threaten their health, safety, and economic well-being. Objective: This study examined the effects of the COVID-19 pandemic in relation to parental perceived stress and child abuse potential. Participants and Setting: Participants included parents (N = 183) with a child under the age of 18 years in the western United States. Method: Tests of group differences and hierarchical multiple regression analyses were employed to assess the relationships among demographic characteristics, COVID-19 related disruptions, mental health risk, protective factors, perceived stress, and child abuse potential. Results: Greater COVID-19 related disruptions and high anxiety and depressive symptoms are associated with higher perceived stress and child abuse potential. In addition, higher perceived stress is associated with higher child abuse potential. Conversely, greater parental support and perceived control during the pandemic may have a protective effect against perceived stress and child abuse potential. Results also indicate racial and ethnic differences in COVID-19 related disruptions, but not in mental health risk, protective factors, perceived stress, or child abuse potential. Conclusion: Findings suggest that although families experience elevated stressors from COVID-19, providing parental support and increasing perceived control may be promising intervention targets.

Published: June 2020

Background. It has been proposed that muscle architecture can be associated with sprint performance and the risk of sustaining a muscle injury. During puberty, sprint performance as well as muscle injury risk increases in young soccer players. In this study, we investigated the changes in m. biceps femoris long head (BFlh) cross-sectional area (ACSA), fascicle length (FL) and pennation angle (PA) and sprint performance as well as their relationship in under 13 to 15 youth soccer players. Methods. In total, we measured 85 youth soccer players in under 13 (n=29, age=12.5 y (SD=0.1), height=155.3 cm (6.2), weight=43.9 kg (7.6)), under 14 (n=25, age=13.5 y (0.3), height=160.6 y (7.7), weight=47.0 kg (6.8)) and under 15 (n=31, age=14.4 y (0.3) , height=170.0 cm (7.7), weight=58.1 kg (8.8) ) teams of three high level soccer clubs. We used ultrasound to measure BFlh ACSA, FL and PA. We performed sprint tests to assess 10m and 30m sprint time, maximal velocity (vmax) and maximal acceleration (amax). We calculated Pearson’s r and 95% compatibility intervals to assess the relationship between sprint ability, maturity ratio, chronological age and architectural parameters. In addition, we calculated the best set of predictors for sprint ability using multiple regression models.Results. All muscle architectural parameters increased from the under 13 to the under 15 age group (BFlh ACSA: 37%, BFlh FL: 11%, BFlh PA: 8%). All sprint performance parameters improved from the under 13 to under 15 age categories (30m time: 7%, 10m time: 4%, vmax: 9%, amax: 7%). BFlh ACSA was correlated with 30m sprint time (r = -0.61 (95% CI = -0.73, -0.45)) and vmax (r= 0.61 (0.45, 0.72)). The correlation for maturity ratio with assessed parameters were larger compared to the correlation for chronological age. A combination of BFlh ACSA, FL, chronological age and height best predicted sprint parameters. Discussion. Parallel to improvements in sprint performance, muscle architectural parame-ters increase from the under 13 to under 15 age groups. BFlh ACSA seems to be related to sprint performance in youth soccer players. BFlh ACSA and chronological age are the main predictors of most sprint parameters.

Authors: Cavdar F. Y. , Yasar H. , Cavdar K.
Published: June 2020

Resistance spot welding is an extensively used production process in the industry. The joint strength of sheet metal parts bonded by resistance spot welding is expected to be sufficient. Furthermore, it is desirable that the appearance of the welding area be acceptable on visible surfaces. In regard to having an adequate surface appearance on the welded area, is necessary to remove the color changes on the unpainted surfaces and to eliminate the indentations caused by the welding pressure. In this study, an objective evaluation was performed using the color measurements of the test samples joined with resistance spot welding. The effects of welding parameters on surface appearance were investigated and the most suitable settings for the appearance of the welded surface were discussed.

Published: June 2020

Bireyi kendisine merkez olarak alan edebiyat, insanlığın ortak hafızası ve vicdanıdır. İnsan ise duyguları, düşünceleri ve karmaşık zihin dünyasıyla tanımlanması zor bir varlıktır. Roman, edebî türler içinde insan gerçekliğini uzun soluklu bir kurgu içinde vermesi ve anlatı dünyasının imkânlarından sonuna kadar faydalanması özelliğiyle kültürel, toplumsal değişim ve dönüşümün bir aynası niteliğindedir. Kendini oluşturmaya devam eden bir tür olarak romanın gücü, diğer edebî türlerin yapamadığı, kendini modern yaşamın şaşırtıcı hızına koşut bir şekilde güncellemesinde yatar. Türk edebiyatında romanın doğuşundan itibaren yazarlarımız, insanı ve onun dünyasını roman sanatının kendilerine sağladığı imkânlar ölçüsünde anlatmaya özen göstermişlerdir. Günümüz Türk romanının önemli isimlerinden olan Ayşe Kulin de romanlarında çağının tanığı ve sesi olarak, kadınları anlatan tutumuyla dikkati çekmektedir. Gece Sesleri romanı, vakaların geçtiği dönemin ekonomik, sosyal, kültürel koşullarını romancının özgün bakış açısıyla verirken tarihsel zamanın panoramasını da romanına bir arka plan olarak yerleştirmektedir.Toplum hayatında yaygın olarak görülen cinsiyetçi anlayış, geleneksel kültürümüzün de bu anlayışa sağladığı kültürel dayanakla en belirgin tavrını kadına yönelik şiddet ve ötekileştirme olgusunda göstermektedir. Kadına yönelik şiddet olgusu diğer bilim dalları tarafından da incelenmekle beraber insanı anlatan modern bir edebî tür olan romanda, toplumsal bir duyarlık temelinde işlenmektedir. Bu yazıda, Gece Sesleri adlı eserde kadına yönelik olarak gerçekleştirilen şiddetin değişik boyutları incelenerek romanın anlam dünyası içinde önemli bir nesne konumunda olan kadına dair bir farkındalık oluşturmak hedeflenmektedir.

The Worth of the ‘While’
Authors: Eräsaari Matti
Published: June 2020

Taxation always involves an element of value quantification, since to tax is also to implement a measuring scale—a process that is usually taken for granted. But when it becomes necessary to determine the taxational value of abstract time or labor, it is also necessary to outline the principles upon which such value is established. This article discusses the conflicting views of the Finnish Tax Administration and the Helsinki Timebank, a local exchange network, about how to tax ‘whiles’, the community currency that equates to one-hour stretches of work time. Based on a 2013 ruling by the Finnish tax authority and the Timebank’s responses to it, the article asks, to what degree can the choice of a particular ‘standard’ be taken as a ‘moral’ choice?

Published: June 2020

In the present study, semi – batch experiments were conducted to investigate the efficiency of ozone microbubbles (OMBs) in the treatment of aqueous dye solutions methylene orange under different reaction conditions such as  effect of initial solution pH , ozone generation rate and initial MO-concentration. The results showed that the removal of MO by OMBs were very high at the acidic and alkaline media and upon increasing the generation rate of ozone from 0.498 to 0.83 mg/s, the removal efficiency dramatically increased from 75to 100% within 15 min. The rate of oxidation reaction followed a pseudo first- order kinetic model. The results demonstrated that OMBs is efficient in terms of the decline of methylene orange concentration and its total mineralization.

Published: June 2020

BACKGROUND: Strawberry (Fragaria x ananassa Duch.) is among the most widely consumed fruits in the world and its cultivation is increasing worldwide. This continuous increase in its cultivation acreage is concomitant with the development of new varieties by numerous breeding programs. Due to strawberry is a microclimatic crop, the behaviour of the cultivars could vary depending on many agronomical and environmental factors such as temperature or humidity. Thus, for some traits, data from a single crop season may not be enough to suspect the behaviour of a specific variety. OBJECTIVE: Generate information that allows knowing the consistency of different characteristics over time. METHODS: For four consecutive years, organoleptic and yield related traits were analysed in five strawberry cultivars. RESULTS: The overall result is a significant effect of genotype on all yield relates and organoleptic parameters studied. Our study also inferred an effect of environment, temperature and relative humidity, mainly on yield parameters. However, not all cultivars were similarly affected. CONCLUSIONS: With the information generated from this work, it will be possible to establish, based on the consistency of the cultivar trials over time, the suitability of using the results of a single season to predict the behaviour of a particular cultivar.

New Trends Towards Enhanced Structural Efficiency and Aesthetic Potential in Tall Buildings: The Case of Diagrids
Authors: Scaramozzino Domenico , Carpinteri Alberto , Lacidogna Giuseppe
Published: June 2020

Due to the increasing number of people and activities within the cities, tall buildings are exploited worldwide to address the need for new living and commercial spaces, while limiting the amount of used land. In recent decades, the design of tall buildings has undergone a remarkable improvement, thanks to the development of new computational tools and technological solutions. This has led to the realization of innovative structural systems, like diagrids, which allow the achievement of high structural performances and remarkable architectural effects. In this contribution, a thorough and updated review of diagrid structural systems is provided. Simplified methodologies for the preliminary design and structural analysis are reported. Special attention is also paid to the optimization of the structural response based on the geometrical pattern. A discussion of the effect of local deformability, stability and shear-lag phenomenon is carried out. Results from nonlinear and dynamic analyses for the seismic assessment of diagrid systems are reported, and attention is also paid to the recent research on diagrid nodes. Eventually, an overview of twisted, tapered, tilted and freeform diagrid towers is carried out, with a final mention of hexagrids, another recent evolution of tubular systems for tall buildings.

Published: June 2020

Pain is an easily recognized sensation that is experienced by humans and animals alike. However, the process behind the production of the pain experience is a complex pathway that requires parallel integration of both the emotional and sensory experiences together with noxious perceptual information registered by multiple layers of our brain structure with the purpose of defending our body from harm’s way. Here, the complete protocol that is being adapted for inflammatory pain study in animals induced by different phlogogenic agents and different assessment methods were elaborated along with the underlying mechanism of actions. This provides a concise idea and improves our scientists’ understanding of inflammatory pain management in future research.
Massive MIMO Systems for 5G
Authors: Chataut Robin , Akl Robert
Published: June 2020

The global bandwidth shortage in the wireless communication sector has motivated the study and exploration of wireless access technology known as massive Multiple-Input Multiple-Output (MIMO). Massive MIMO is one of the key enabling technology for next-generation networks, which groups together antennas at both transmitter and the receiver to provide high spectral and energy efficiency using relatively simple processing. Obtaining a better understating of the massive MIMO system to overcome the fundamental issues such as pilot contamination, channel estimation, precoding, user scheduling, energy efficiency, and signal detection is vital for the successful deployment of 5G and beyond networks. Some of the recent trends in massive MIMO are terahertz communication, ultra massive MIMO (UM-MIMO), visible light communication (VLC), machine learning, and deep learning.

Authors: Tan Kun , Markovych Sergii , Hu Wenjie , Shorinov Oleksandr , Wang Yurong
Published: June 2020

Cold spray technology is a method of deposited metal coatings by high-speed particle impact, especially in the preparation of metal alloy materials (Cu alloys, Ti alloys, Al alloys, Ni-based alloys, Mg alloys, stainless steels, and high-temperature alloys, etc.) The performance is particularly outstanding. The sprayed materials have better mechanical properties, mechanical properties, and service life, such as tensile strength, fatigue strength, and corrosion resistance. Cold spray technology can prepare corrosion-resistant coatings and high-temperature coatings, Wear-resistant coatings, conductive coatings, and anti-oxidation coatings and other functional coatings. From the perspective of process technology and equipment design, cold spray technology can be applied to the field of additive manufacturing technology, which not only reflects the repair function but also the manufacturing function, and applies cold spray technology and repairs the parts produced by additive manufacturing – Selective Laser Melting technology. The defects and problems are of great significance. This article summarizes the repair process and technical characteristics of cold spray technology, and repairs and protects the Cu, Ti, Al, Ni, Mg, and stainless steel and other metals and their alloys from corrosion, fatigue, and wear. The maintenance is reviewed, and the application of combining cold spray technology with additive manufacturing – Selective Laser Melting technology is proposed. Many materials can be used in the field of cold spray technology and Additive Manufacturing – Selective Laser Melting technology. In the communication between the two, the combination of technology and method is of great significance; the influence of spraying parameters of cold spraying technology (such as powder particle shape, spraying angle, spraying distance, critical speed and temperature of particles and substrate, etc.) on spraying effect and efficiency are proposed. Finally, the development of cold spray technology: post-processing of parts, critical speed and numerical simulation are possible.
Risk Management in the Context of Information Modeling Technologies for Construction Objects: Features and Opportunities
Authors: Vereshchagin V. V. , Shemyakina T. Yu.
Published: June 2020

Risks are inevitable in any construction project. Risk management methodology is used to address or mitigate their impact in the management of construction projects. In recent years, in the fields of architecture and construction, the likelihood of risks is increased due to the increasing structural complexity, the volume of construction works of the project, the application of new and complex construction methods. However, experience with risk management has shown limited practical impact on the development of systemic risk management in the construction project. Information modeling (BIM) technologies play an important role in risk management during the design, construction and maintenance phases of a building facility. Based on the development of information technologies, risk management should be integrated with modern IT processes of construction project management. Since BIM implementation for risk management of construction projects is still limited, the BIM system implementation must be developed to address risks throughout the construction project lifecycle. This article discusses the applications of BIM for building risk management during the lifecycle of a project. These recommendations illustrate the use of BIM in risk identification, response and monitoring. The findings show that one of the most significant issues is the lack of regulations to align BIM with risk management in the project development and execution process. The development of regulations should cover the model of risk migration, cycles of risk management, flexible structure of the risk management service at all stages of the life cycle of the construction project.

The results of the study showed that tamarind (Tamarindus indica L.), candlenut (Aleurites moluccana (L) Willd.), areca nut (Areca cathecu L.), and betel (Piper betle L.) is the major of NTFP commodities in Sikka district. The socio-economic conditions of NTFP farmers on surrounding farmer are not prosperous yet, and highly depend on the sustainability of NTFP production. Community initiatives to conserve and regenerate NTFPs through agroforestry need to be improved, especially in improving the rate of plant growth. Technical assistance to increase community capacity in conservation and development of NTFPs around forest areas and private land is still needed.
Concentración del crédito rural y la pobreza en Colombia
Authors: Cala Amaya Myriam Mercedes
Published: June 2020

Se analiza el relacionamiento entre la concentración de la pobreza a nivel departamental en Colombia y la asignación del crédito de fomento agropecuario, teniendo en cuenta los departamentos como también el tipo de tomador de crédito (pequeño, mediano y grande), a través de FINAGRO o del Banco Agrario de Colombia para el periodo 2006 – 2016. Se considera el Modelo de Análisis de Agrupamiento, jerárquico, aglomerado y por encadenamiento medio. Se analizan 19 departamentos del país cuyo Índice de Pobreza Multidimensional (IPM) se encuentra por encima de la media nacional. Además, se considera el Índice de Participación Relativa (IPR) por departamento, por línea y por usuario. Se muestra como la política de crédito de fomento en el país presenta alta concentración en departamentos típicamente receptores y se canalizan principalmente para los medianos y grandes productores. De esta manera, se concluye que los pequeños propietarios en los departamentos más alejados del centro del país reciben menores asignaciones contribuyendo a que sus niveles de pobreza perduren en el tiempo.

Published: June 2020

La insolvencia empresarial afecta tanto a las empresas que entran en este proceso como a sus proveedores de bienes y servicios. Esta investigación hace uso de indicadores financieros para pronosticar la insolvencia empresarial con un año de anticipación. El estudio fue aplicado a 2.988 empresas que reportaron información financiera a la Superintendencia de Sociedades (Colombia) durante el año 2017, de las cuales 127 entraron en proceso de insolvencia en 2018. El pronóstico considera indicadores financieros de liquidez, rentabilidad y endeudamiento, y contrasta los resultados de la regresión logística con el algoritmo boosting. Se concluye que los indicadores financieros permiten pronosticar la insolvencia empresarial, sin embargo se debe recurrir a metodologías no tradicionales como el algoritmo boosting que consideren la asimetría de la información.
Optimization and Experimental Investigation of the Ability of New Material from Aluminum Casting on Pumice Particles to Reduce Shock Wave

Published: June 2020

Some materials, due to their inherent properties, can be used as shock and wave absorbers. These materials include foam and porous materials, in this study, specimens were made by casting aluminum on porous mineral pumice. Which can replace aluminum foam in some applications with lesser cost, at first, the material is compared with aluminum foam using compression test and quasi-static loading diagram. Which compares the diagrams of these two materials showing the similarity of their behavior in quasi-static loading. Initially, the elastic bending of the walls causes an elastic region in the stress-strain curve of the material. Then, the plastic collapsing of the cells forms a large and relatively smooth region along the elastic and after the plastic collapse of the cells, the area known as foam densification begins where the density of the foam closer to the density of its constituent material causes a sudden increase in the stress level in the specimen. These steps have also been seen in the quasi-static loading of aluminum foam. Then, by using numerical simulations with ANSYS AUTODYN and the shock tube test the ability of these specimens were investigated to reduce the shock wave. The behavior of the material in this case is also very similar to the results of previous studies on aluminum foam.

Sesame (Sesamum indicum L.), is the most ancient and important oilseed crop for its good quality edible oil. Much variability among genotypes exists in sesame which helps the breeder to choose good parents in hybridization. In the present study, 30 genotypes were studied for 12 morphological traits. Correlation analysis exhibited that seed yield per plant was positive and significantly correlated with capsules per plant and 1000-seed weight. Apart from morphological data, initial genotyping was conducted for 32 microsatellites but finally only polymorphic primers were selected for genetic diversity study. Estimated polymorphism information content (PIC) value ranged from 0.07 to 0.87 and SSR 24 showed to be highest at 0.87. The dendrogram was constructed using the software NTSYS Pc Ver. 2.20 based on morphological and molecular data. Geographical diversity did not corroborate with genotypic diversity as the cluster composition revealed that genotypes belonging to different geographical origin grouped in the same cluster.

Authors: Islam Saiful , Jahan Nargis
Published: June 2020

A field experiment was conducted to evaluate the effect of TIBA (0, 10, 20, 50 and 100 ppm) on the growth and yield attributes of BARI Chola-7 laid out in RBD. Foliar application of TIBA at flower initiation stage, decreased plant height significantly with increasing concentrations of TIBA. Number of branches and leaves per plant were found to increase from 21 and 14 days after spray (DAS) onwards, respectively due to all the TIBA treatments and the maximum number of branches and leaves per plant were recorded due to 100 ppm TIBA which was statistically at par with 20 and 50 ppm TIBA. Dry matter per plant was recorded maximum from 21 DAS up to harvest due to 20 ppm TIBA. Except 100-seed weight, other yield contributing characters viz. number of seeds per plant, yield per plant, yield per hectare were also found to maximum due to 20 ppm TIBA treatment. The highest harvest index was recorded from 20 ppm TIBA.

The crude methanolic extract of the root bark of Pongamia pinnata was taken into consideration to isolate secondary metabolites. A total six known natural compounds were separated and purified by various chromatographic techniques and five isolates were identified as flavonoid derivatives such as pongachromene (1), kanugin (2), karanjin (3), demethoxykanugin (4), dimethoxypongapine (5) and the other is a triterpenoid (6). The pure compounds as well as petroleum ether, dichloromethane and ethyl acetate soluble fractions of crude methanolic extract were evaluated for bioactivities using established methods. In vitro antioxidant activity was studied by DPPH radical scavenging method using butylated hydroxyl anisole as standard. Among the pure compounds, kanugin and pongachromene showed significant antioxidant activity with the IC50 values of 27.20 ± 0.39 μg/mL and 43.53 ± 0.63 μg/ml, respectively as compared to the standard (23.87 ± 0.09 μg/ml), whereas karanjin, demethoxykanugin and dimethoxypongapine demonstrated moderate antioxidant activity. Mild thrombolytic activity was observed by different fractions with clot lysis ranging from 18.49 to 29.35% as compared to standard streptokinase (79.12%). The different solvent fractions and pure isolates showed very mild antimicrobial activity with zone of inhibition of 7.5 - 10.0 mm against the tested microorganisms using azithromycin and ketoconazole as standards. In the brine shrimp lethality bioassay, the dichloromethane, ethyl acetate, and methanol soluble fractions revealed significant lethality with LC50 values of 0.67 ± 0.05, 0.61 ± 0.13 and 0.56 ± 0.10 μg/ml, respectively as compared to standard tamoxifen (LC50 value 0.34 ± 0.09 μg/ml).

Published: June 2020

Marine sponges have been known as the source of natural products. Various metabolites with potent bioactivities have been reported from this organism. The current study aims to investigate the anticancer potency of three marine sponges namely Diacarnus debeauforti, Haliclona amboinensis and Agelas cavernosa collected from Barrang Lompo Island, South Sulawesi, Indonesia. The ethyl acetate extracts of the sponges were screened against T47D breast cancer cells and HeLa cervical cancer cells by using the MTT method. The results showed that these sponges demonstrated anticancer activity against both cancer cell lines. The lowest IC50 of 18.2 μg/ml was given by the extract of A. cavernosa against T47D cell line, while in the screening against HeLa cancer cell line, the extract of D. debeauforti revealed the highest potency with IC50 of 15.7 μg/ml. Our results suggested that the marine sponges namely D. debeauforti, H. amboinensis and A. cavernosa can be good candidates for the development of anticancer agents.
