PREPARATION OF DOPED TiO2 PHOTOCATALYSTS AND THEIR DECOLORIZATION EFFICIENCIES UNDER SOLAR LIGHT
Authors: KAYA Dila , TÜRKTEN Nazlı
Published: September 2020

Photocatalysis has gained a great interest for the degradation of organic pollutants in aqueous media. This effective advanced oxidation technique is basically based on the oxidation of the target molecule by hydroxyl radicals. The most widely preferred and powerful photocatalyst is titanium dioxide (TiO2), but it has limited use under solar light because of its band gap energy. This is a major drawback for various possible applications. In order to overcome this disadvantage, doping the photocatalyst with metals and non-metals to narrow the band gap can be applied. In this work, we have prepared visible light active photocatalysts by using wet-impregnation method. Decolorization of two different classes of dyes, Rhodamine B and Congo Red, was carried out under simulated solar light with doped TiO2. The photocatalytic performances of non-metal doped (C, N, Se), metal doped (Cu, Fe) and codoped (N/S) TiO2 photocatalysts were investigated by UV-vis studies and removal percentage calculations.

Published: September 2020

3D Finite Element Analysis (FEA) was performed to determine flexural and elastic lateral-torsional buckling behavior of cellular beam by using European steel shape and quality. An experimental study from literature was chosen for verification of the Finite Element Model (FEM). Parametric studies were carried out with a verified numerical model to investigate the effect of some geometrical properties of the cellular beam such as hole diameter, hole spacing, and various types of rigidity plates on elastic buckling and flexural capacity of the beam. Geometric and material nonlinear behavior were included in FEM. In the other part of the study, the theoretical calculation method of Lateral Torsional Buckling (LTB) with gross section and with net section properties was also investigated. The study showed that the LTB calculation method given by AISC360-16 and TSDC-2016 design guides provided more accurate result with net cross-section for European steel shapes and quality.
USE OF AGILE AND OPEN INNOVATION APPROACHES IN EXECUTING THE PROJECTS: A FIELD STUDY ON PROJECT MANAGERS
Authors: ÇUBUKCU, PMP® Ahmet
Published: September 2020

Agility and open innovation are two concepts that support each other as well as being approaches that contribute a lot to the project managers. While they seem to be different methodologies, the fact that particularly they are collaborative and knowledge-based approaches and that they aim to attain innovative outputs by looking at the events from similar perspectives bring the open innovation and agility close to each other. This study strived to measure the awareness of the project managers about agile and open innovation approaches in executing the projects. While it was observed in the study results that an awareness about and use of the two approaches started to form, it appeared that the projects in which these two approaches are used differed in a certain extent from each other.

SAMPLE ENTROPY ANALYSIS OF HEART RATE VARIABILITY IN RR INTERVAL DETECTION
Authors: ALCAN Veysel
Published: September 2020

Entropy is a robust method that is able to measure irregularities or the general behavior of the complex time series which could be continuously interact with many different and independent factors in time. This study aimed to investigate the sample entropy measurement of heart rate variability (HRV) for evaluating of 50Hz interference and baseline wander (BW) noise effects on RR interval. Three different synthetic electrocardiogram (ECG) signals were recorded using the simulator device. Sample Entropy (SampEn) values of full length and windowed length of data were calculated to track and identify RR intervals. It was found that adult normal sinus rhythm (NSR) signal without noise had the most regular and consistent results while adult ECG signal with BW noisy had the most irregular and inconsistent results. Furthermore, the BW noisy had more effect on irregularity ECG signal than 50 Hz interference. Consequently, the SampEn provided the measurement of irregularity and randomness of ECG data. However, it was found that the determination of RR intervals for classification and decision support systems was not practical in real-time analysis of HRV from raw ECG recordings because of noisy affect.

Divergent Refugee and Tribal Cosmopolitanism in Dharamshala
Authors: Christopher Stephen
Published: September 2020

This article analyses the divergent, and occasionally overlapping, trajectories of Tibetan refugee and Gaddi tribal cosmopolitanism in Dharamshala, North India. In a place self-consciously branded as cosmopolitan, where Tibetan ethnocommodification is the primary symbolic currency, practices of inclusivity can broadly give way to Gaddi exclusions. Cosmopolitanism as an ordering ideology and set of intercultural competencies, often predicated on the dyadic relationship between Tibetan refugees and international tourists, propels Gaddi resentments and coarsens intergroup sociality. This does not mean, however, that Gaddis are forever consigned to tribal backwardness and reactionary forms of communal aspiration. Gaddis have forged an alternate, grounded cosmopolitanism based on cultural skills fostered through pastoral transhumance, seasonal labour migration corresponding with foreign tourists and ongoingethnopolitical redefinition of what it means to be tribal itself. By seeing past utopian propaganda and dystopian exaggerations about Dharamshala, a richer tapestry of group relations emerges which reveals divergent cosmopolitanisms in the promotion of shared struggles for state recognition and cultural preservation.
Rapid Adoption of Telehealth at an Interprofessional Student-Run Free Clinic
Authors: Phan Ryan Cao Vinh , Le Dung Van , Nguyen Alexander , Mader Kari
Published: September 2020

Introduction: Student-run free clinics (SRFCs) have become important primary care homes during the COVID-19 pandemic. With students pulled from clinical sites, funding deficits, SRFCs’ voluntary nature, and no best practices for telehealth SRFCs, many have been forced to close. This report shares a systematic approach for implementing a telehealth clinic along with initial outcomes from the Dedicated to Aurora’s Wellness and Needs (DAWN) SRFC.
Methods: We utilized pilots with students, community volunteers, and patients to identify a telehealth platform. We implemented weekly plan-do-study-act (PDSA) cycles to develop a feasible interprofessional telehealth model. Key PDSA cycle goals included seamless utilization of platform, identification of necessary team members, appropriate scheduling of patients and volunteers, integration of interprofessional learners, positive patient and volunteer experience, and process for identifying and addressing patient social needs. Measured outcomes included total visits, no-show rates, and chief complaints addressed.
Results: Outcomes from PDSA cycles included a resultant telehealth clinic team and model, workflow for outreach for social needs screening and navigation, and team training guides. Visit data and no-show rates from January 2020 through July 2020 demonstrated total visits returned to 60% of pre-COVID numbers while no-show rates decreased significantly below pre-COVID rates. A range of acute and chronic concerns were successfully managed via telehealth.
Conclusion: SRFCs are poised to continue serving an important role in caring for the country’s most vulnerable populations. The DAWN telehealth implementation process, outcomes, and resultant protocols may help inform other SRFCs seeking to establish telehealth services.
O problema do complemento circunstancial e a oração subordinada adverbial em espanhol
Authors: Pereira Shirley Sousa
Published: September 2020

Neste trabalho faremos uma breve revisão teórica acerca da problemática classificação do complemento circunstancial na gramática tradicional espanhola, na qual discutiremos a sua suposta identidade funcional com o complemento adverbial, assim como o seu caráter marginal no predicado verbal (ALARCOS LLORACH, 1970; ROJO, 1990). Discutiremos sobre a viabilidade das propostas de Álvarez Martínez (1992) e de Gutiérrez Ordóñez (2002) de incluir a categoria do advérbio ao grupo nominal dos substantivos e adjetivos e de que o complemento circunstancial pode assumir uma função nominal. Tais considerações trazem como consequência a inclusão das orações subordinadas circunstanciais e adverbiais (próprias e impróprias) no grupo das orações subordinadas substantivas.

Authors: Li Yiming , Liu Xingan , Qi Fengsheng , Wang Li , Li Tianlai
Published: September 2020

The fully passive solar energy utilization system of Chinese solar greenhouse is efficient for ensuring year-round cultivation of vegetables, owing to the high amount of heat charge and discharge characteristic of the north wall enclosure. In the present research, the thermal performance is investigated using CFD. A 3-D mathematical model has been established to evaluate the wall thickness, layered configuration and material property. The predicted thermal environments are in good agreement with the experimental measurements, indicating the reliability of the established numerical model. The results showed that the increase of north wall thickness could cause the waste of resources due to the thermal masses mainly concentrate in the superficial layer. Constructing layered configuration is rec-ommended for the north wall which uses Styrofoam in the outer layer to reduce heat loss. Nevertheless, the property of north wall material has little effect on the thermal environment. The research results, thus obtained, will give good guidance for completing the Chinese solar greenhouse engineering database and optimizing the solar energy utilization.

Authors: Ligus Grzegorz , Masiukiewicz Maciej , Anweiler Stanisław , Wasilewski Marek
Published: September 2020

Energy efficiency is a key issue of sustainable development. During the design of industrial devices, it strives to achieve the highest possible energy efficiency. In the industrial systems, two-phase flow is a difficult task, especially the prediction, and maintenance of the two-phase flow regime. That is why this research proposes the evaluation and choice of an algorithm that will give a hint of the device design for which the hydrodynamic conditions of the two-phase mixture flow may be evalu-ated. The tests were carried out in a rectangular vertical narrow channel, as this type of device is in common use. The work aimed to show which algorithm is better for such evaluation. Parameters such as pressure drop, heat, mass, and momentum transfer are influenced by the phase velocity field. Still, various models are used for the determination of the velocity field. Therefore, there is a problem of choosing a model that will give the results closest to the real conditions. Flow visualization gives the non-invasive determination of the actual velocity field. An analysis of the velocity field was performed, which showed that for different two-phase flow regimes there are differences for given algorithms. The following algorithms were used to determine the velocity vector field: adaptive correlation method and adaptive particle image velocity method were used which are the parts of the general digital particle image velocimetry. The determination of the velocity fields in the quantitative and qualitative assessment of a given two-phase flow re-gime was obtained. The result of the research is the evaluation of algorithms for characterization two-phase gas-liquid flow.

UJI IN VITRO AKTIVITAS ANTIBAKTERIA DARI EMPAT ISOLAT BAKTERI ENDOFIT BATANG Avicenniamarina (Forssk.) Vierh.
Authors: Indrawati Ida , Monica Devira
Published: September 2020

Avicennia marina (Forssk.) Vierh. (Mangrove api-api putih) merupakan jenis tumbuhan mangrove yang umum ditemukan di Indonesia. A. marina diketahui mengandung senyawa bioaktif yang dapat digunakan sebagai anti-oksidan, anti-tumor, anti-inflamasi, anti-alergi, dan anti-mikroba. Senyawa bioaktif pada A. marina juga dapat dihasilkan oleh bakteri endofit yang hidup pada jaringan tumbuhan A. marina karena adanya transfer genetik antara bakteri endofit dengan inangnya. Potensi anti-mikroba dari bakteri endofit yang diisolasi dari A. marina diharapkan dapat digunakan untuk menghambat pertumbuhan bakteri patogen. Penelitian ini dilakukan untuk menguji aktivitas anti-bakteri dari bakteri endofit yang diisolasi dari batang A. marina terhadap bakteri pathogen Methicillin-resistant Staphylococcus aureus (MRSA) dan Klebsiella pneumoniae. Metode yang digunakan adalah uji aktivitas anti-bakteri metode difusi Kirby- Bauer dengan dua kali pengulangan. Hasil pengujian menunjukkan bahwa empat isolat bakteri endofit dari batang A. marina memiliki aktivitas anti-bakteri yang cukup tinggi (kisaran diameter zona hambat 8,9-13,17 mm) terhadap MRSA dan K. pneumoniae.
On the Compatibility of Evolutionary Biology and Theism
Authors: Lemos John
Published: September 2020

Human beings are the products of many thousands of years of biological evolution, and this process occurs in accordance with the principles of natural selection originally articulated and defended by Charles Darwin and developed and defended further in the modern synthesis of the 20th century.  In this paper, I consider how it may be thought that this fact threatens the rationality of belief in the Christian God.  These threats are countenanced with respect to issues of design, randomness, suffering, and the objectivity of ethics.  I argue that while some versions of Christian belief, such as those grounded in a literalist reading of the Genesis creation story or those committed to the image of God thesis, may be threatened by a Darwinian worldview, there are nonetheless plausible versions of Christian belief that are immune to Darwinian challenges.
Metalinguistic Agnosticism, Religious Fictionalism and the Reasonable Believer
Authors: Hesse Jacob
Published: September 2020

With the position, he labels as “new” or “metalinguistic agnosticism” Robin LePoidevin can avoid some problems with which fictionalists about religious language are confronted. Religious fictionalism is a position according to which all religious claims[1] are considered to be false when taken at face value. But because fictionalists about religious language think that certain religious worldviews have pragmatic benefits, they interpret several claims in such worldviews as true in fiction. This enables them to gain pragmatic benefits because they live as if a certain religious worldview were true. Nonetheless, they don’t believe that the respective worldview represents the non-fictional reality.[2][1] In the following I understand a “religious claim“ either as the claim that God exists or as a claim that presupposes the existence of God. Since also Le Poidevin focuses on theistic religions I want to keep this focus in my response. Nonetheless, it should be kept in mind that religious fictionalism is not restricted to theistic religions. I also think that metalinguistic agnosticism and the argumentation in this paper could in principle be extended to non-theistic religions.[2] A defense of religious fictionalism can be found in for example Andrew S. Eshleman, “Can an Atheist Believe in God?”, Religious Studies 41, no. 2 (2005) and Andrew S. Eshleman, “Religious Fictionalism Defended: Reply to Cordry”, Religious Studies 46, no. 1 (2010).

La construcción artística del espacio indígena y los paisajes itinerantes
Authors: Garrido Elisa
Published: September 2020

Desde el punto de vista de los estudios del paisaje concebidos en sentido cultural, existe una laguna en lo referido al contexto pre colonial hispanoamericano. La literatura nos suele remitir a Alexander von Humboldt como el precursor y a la escuela del Río Hudson como mayor exponente. Sin embargo, un estudio crítico de los paisajes culturales previos a la producción de viajes y expediciones científicas podría dar como resultado una nueva aproximación al género del paisaje y a la cartografía del conocimiento de la naturaleza.  Este texto propone una aproximación a esas representaciones previas en las que el paisaje no era paisaje.
“Harta de sombras estoy”. La Dama de Shalott de Alfred Tennyson como metáfora del ideal de feminidad victoriano y su reflejo en el imaginario pictórico decimonónico.
Authors: Soto Delgado Rocío
Published: September 2020

En un clima de revivalismo medieval y recuperación de la tradición artúrica, Alfred Tennyson (1809-1892) escribe en 1833 el que se convertiría en uno de sus poemas más célebres, La Dama de Shalott. En él, recuperaría la figura de la Doncella de Astolat creada por Sir Thomas Malory en La muerte de Arturo (1485). Pronto se convertiría en una de las heroínas paradigmáticas del poeta y uno de los motivos iconográficos preferidos de artistas prerrafaelitas y victorianos del siglo XIX y principios del XX. Tanto el poema como las imágenes, se tomaron como ilustraciones de actitudes victorianas hacia la reclusión de las mujeres en el área doméstica y la privación de su sexualidad.

Published: September 2020

This study investigates the sensitivity of physical parameterization schemes in two regional dynamic models clWRF (the climate Weather Research and Forecasting) and RegCM (the Regional Climate Model) in the simulation of tropical cyclones (TCs) over Western Pacific Ocean and East Sea. The experiments include 12-cases for clWRF model and 6-cases for RegCM model were conducted to run the simulation, with the same domain parameters, resolution 25 km. Results show that the clWRF can simulate TCs well with the Betts-Miller-Janjic convection scheme and WSM6 microphysics, in which convection schemes are more influential, and the RegCM is with the Kain-Fritsch convection scheme and Zeng oceanic flux. Regarding the number of TCs simulation, most of them are higher than observed and CFSnl (Climate Forecast System analysis) data, therein the RegCM is higher than the clWRF.
