Design of intelligent traffic load balancing (ITLB) mechanism for software defined data center (SDDC)
Authors: Balakiruthiga B , Deepalakshmi P
Published: December 2022

The reinforcement learning strategy is adopted for software defined data centers, since it involves software agents to accomplish decision making through continuous learning of environment during drastic traffic. In this research work, we are proposing an intelligent routing algorithm by considering controller capacity and link capacity as the routing metrics. In addition, our approach takes care of migrating switches whenever a controller is over utilized. Distinct reinforcement learning agents are used to handle path computation and switch migration phase individually. Our key objective is to provide intelligent traffic load balancing approach in software defined data center using two distinct software agents. We observe that our proposed approach has achieved nearly 1.2 to 2.1 milliseconds of less latency, 2.5 milliseconds of less response time and low packet loss percentage around 1 to 2.5% and hence overall network throughput improvement is about attained 30 to 50% than other existing approaches through simulation.

Authors: Wang Chen , Hu Zhan-Wei , Li Zhi-Ying , Zhao Ming-Hui , Chen Min
Published: December 2022

Background
Pulmonary infection is one of the leading causes of death in patients with ANCA-associated vasculitis (AAV). Fiberoptic bronchoscopy and bronchoalveolar lavage fluid (BALF) assays are useful diagnostic methods. In addition to conventional microbiological tests (CMTs), metagenomic next-generation sequencing (mNGS) facilitates rapid and sensitive detection of various pathogens. We aimed to evaluate the advantages of additional BALF mNGS in the management of pulmonary infections in AAV patients.
Methods
Fourteen patients with active AAV and/or suspected infection whose BALF samples were tested by mNGS (BALF mNGS group) and 14 AAV patients whose BALF were tested by CMTs only (CMTs group) were retrospectively included in the study. The results of microbiological tests and adjustments of treatment upon BALF mNGS were described. The durations of antimicrobial treatment, ventilation and ICU stay as well as in-hospital mortality in patients were compared between the BALF mNGS group and the CMT group.
Results
A total of 64.3% (9/14) of patients in the BALF mNGS group had polymicrobial infections, including bacterium, fungus and virus. Patients in the BALF mNGS group received significantly shorter antibacterial treatment than those in the CMT group. Patients in the early BALF mNGS group (symptomatic infection duration before bronchoscopies < 5 days) received significantly shorter antibacterial and total antimicrobial treatments than those in the early CMT group. Patients with pulmonary infections in the BALF mNGS group received significantly shorter ventilation treatment than those in the CMT group. No deaths occurred in the early BALF mNGS group.
Conclusions
Compared with CMT alone, additional mNGS tests may shorten the duration of antimicrobial treatment and ventilation. mNGS might be further pursued as a routine approach for the management of active AAV patients with suspected pulmonary infections.
Studies on sorption properties of ordered mesoporous silica MCM- 41 and SBA-15 toward non-polar α-tocopherol. Part 1. Kinetics of sorption

Published: December 2022

The sorption kinetics of α-tocopherol (TP) was studied on nanostructured silica materials such as MCM-41 and SBA-15. A significant influence of the pore size on the type of kinetics was noted. In case of MCM-41 (pore size 2.7-3.0 nm), the pseudo-second-order model has the best correlation with the kinetic data. The kinetic coefficients are 1-1.5 orders of magnitude higher than those for SBA-15 (pore size 6.0-6.5 nm). Consequently, the sorption equilibrium is established much faster.
For the description of the adsorption behavior of TP on SBA-15 intraparticle diffusion models were applied. In comparison with the Boyd and Weber-Morrison model, the Vermeulen approach describes the best fit with the experimental data. The filling of the large mesopores of SBA-15 results in a higher adsorption capacity of TP compared with MCM-41. It is noted, that increase of temperature in the range 273-318 K leads to decrease of the sorption capacity for both silicas. Raise of the temperature during sorption on MCM-41 results in the increase of the contribution of diffusion inside mesopores in comparison with surface diffusion.
Scars of Pandemics from Lost Schooling and Experience: Aggregate Implications and Gender Differences through the Lens of COVID-19
Authors: Romer Paul , Samaniego Roberto , Jedwab Remi , Islam Asif M.
Published: December 2022

Pandemic shocks disrupt human capital accumulation through schooling and work experience. This study quantifies the range of the long-term economic impact of these disruptions in the case of the COVID-19 pandemic, focusing on countries at different levels of development and using returns to education and experience by college status that are globally estimated using 1,084 household surveys across 145 countries. We find that: (i) Both lost schooling and experience can contribute to significant losses in global learning and output; and (ii) Developed countries may incur greater losses than developing countries, because they have more schooling to start with and higher returns to experience. In addition, the returns to education and experience are separately estimated for men and women, to explore the differential effects by gender of the COVID-19 pandemic. While we uncover gender differences in returns to education and schooling, gender differences in the impact of COVID-19 are small and short-lived, with a loss in female relative income of only 2.5 percent or less mainly due to the greater severity of the employment shock on impact. The methodology employed in this study is easily implementable for future pandemics where global data availability is initially limited.

Simplified vs. Full-Scale Onshore Wind Turbine Models: A Comparative Analysis
Authors: Jahjouh Mahmoud
Published: December 2022

With the growth in demand for renewable energy, the number, size and production capabilities of wind turbines have grown significantly. Such turbines are subjected to high force fluctuations and are prone to damage, thus requiring a robust and accurate structural identification scheme.
Since the modeling of a full scale wind turbine is a rather complex matter, a simplified model for onshore wind turbine tower identification is used in this contribution, followed by a structural identification and damage detection of the turbine tower using a variety of sensor, noise and damage scenarios.
The studied wind turbine is an idling land-based version of a baseline 5-MW reference wind turbine developed by the national renewable energy laboratory (NREL).
More than 1300 test setups were considered and the results obtained were satisfying in terms of accuracy and robustness and encourage the investigation of more complex identification problems such as, but not limited to, soil-structure interaction and the output-only identification of wind turbines, e.g. when input excitations are unknown.

Adolescent suicidal behavior is the most common reason adolescents present to the emergency department in pediatric hospitals. Recently, suicidal behavior has become more common in preadolescent children. It is important to understand the underlying nature of non-fatal suicidal behavior in children and how they may differ from adolescent to implicate unique prevention and management for this population. The current study aims to investigate the psychosocial characteristics associated with suicidal ideation and behaviors in an emergency department sample of 183 children and adolescents aged 7–18. All participants completed a diagnostic interview, self-report and parent-report questionnaire of psychosocial risk factors. Cross-sectional correlational and regression analyses were used to determine significant correlates of suicidal outcomes within the two age groups. The results indicated that among adolescents, suicidal thoughts and behavior were more common in females compared to males, while among children, the prevalence of males and females was similar. Depression was correlated with suicidal ideation for both adolescents and children. Moreover, anxiety and conduct symptoms correlated with suicidal behavior in children, whereas depression, anxiety, and emotional symptoms correlated with suicidal behavior in adolescents. These results add to the growing knowledge about risk factors associated with suicidality among children compared to adolescents, suggesting the importance of targeting different mechanisms in developing assessment and intervention strategies for the two populations.
Increasing the level of gold recovery during the combined processing of gold containing lead-zinc ores
Authors:   Transbaikal State University, Chita, Zvereva N. , Viktor M. ,   Transbaikal State University, Chita
Published: December 2022

The ore of the Novo-Shirokinskoye deposit is processed at the processing plant of JSC Novo-Shirokinskoye Mine according to the gravity-flotation scheme. The technological scheme for processing gold-containing lead-zinc ores consists of two nodes: 1 – gravity; 2 – flotation. The gravity node for the extraction of free gold (the extraction proportion of free gold into the gravity concentrate is not more than 30%) is realized with the help of jigging machines, screw separators and concentration tables. The flotation node includes: collective cycle, including the main, control and two partial operations; lead cycle, including the main, control and one recleaner operation; zinc cycle, which includes the main, control and three cleaning operations. The ore of the Novo-Shirokinskoye deposit belongs to the primary type, since the degree of its oxidation is 3 %. Final (marketable) products obtained at the factory during ore processing of the Novo-Shirokinskoye deposit are: combined lead concentrate of the LC-8 brand, corresponding to TU 1725-002-24722376-2011 "Lead concentrates"; zinc concentrate of the ZC-3 brand, corresponding to TU 1725-001-24722376-2011 "Zinc concentrate". Zinc flotation tailings are dump and stored in a tailings storage facility. Due to the tendency to reduce the lead content in the ore, the dependence of the reduction in the extraction of gold into the flotation concentrate is manifested. Considering the use of the traditional reagent of potassium butyl xanthogenate - C5H9OS2K (further BPX) as a collector, does not give the desired results, a search for combinations with new reagents is required. The object of research is gold–containing lead-zinc ores. The subject of the study is the modes of the flotation process of enrichment of gold–containing lead-zinc ores using the collector BPX and the new reagent Aeroflot BTF 15221 of the company "Kvadrat Plus". The main idea of the work is to increase the efficiency of flotation enrichment of gold–containing lead-zinc ores by determining the optimal combination of the known reagent of the collector BCC and the proposed Aeroflot BTF15221

Authors: García-Marín David , Llera-Sánchez Elena
Published: December 2022

El objetivo de este trabajo consiste en realizar una primera aproximación al análisis de los videojuegos de carácter independiente a fin de explorar sus posibilidades educativas en la enseñanza de la lengua y la teoría literaria en Secundaria, así como conocer las percepciones del profesorado sobre su aplicación en el aula. La investigación contó con dos fases. La primera consistió en la realización de 19 entrevistas cualitativas estructuradas y semiestructuradas a docentes de centros públicos y concertados de Madrid y Castilla-La Mancha. La segunda integró un análisis de contenido de un total de 44 videojuegos independientes para evaluar su potencial educativo y el nivel adecuado para su utilización en Secundaria. Los recursos literarios y estilísticos, la articulación, la oralidad y la expresividad son los principales aspectos de la teoría literaria que, de acuerdo con los sujetos entrevistados, se pueden trabajar con este instrumento. A pesar de sus ventajas (menor coste, mayor complejidad narrativa, duración adaptable al aula y disponibilidad en cualquier plataforma), los docentes manifiestan un elevado desconocimiento de los videojuegos independientes. Servirse de estas composiciones permitiría desarrollar de manera inferencial algunas competencias clave establecidas en el currículo, concretamente las relacionadas con lo literario, lo artístico y lo lingüístico.

Análisis cultural: posibilidades de los datos culturales para la investigación en educación
Authors: Castellanos Uriel
Published: December 2022

El siguiente artículo propone una reflexión a partir de dos frentes de acción sobre el Análisis Cultural (Cultural Analytics) en Educación: por un lado, caracterizar las bases teóricas; y por otro, analizar las bases metodológicas. El análisis cultural se concibe como un campo capaz de generar estudios complejos a partir de conjuntos de datos culturales y sus flujos, dado que proviene de las relaciones entre Computación Social (Social Computing) y Humanidades Digitales (Digital Humanities). Los contextos teóricos y metodológicos desarrollados permiten pensar, visibilizar y comprender las posibilidades en las diferentes comunidades de profesores/investigadores. Del mismo modo, presentamos el Análisis Cultural junto a la perspectiva de la cultura libre, pues con ello fortalecemos su interpretación desde una perspectiva amplia, abierta, creativa, colaborativa, compartida y de democratización del conocimiento. En este sentido, apostamos por una perspectiva donde el software presente en nuestros datos culturales, como características datificadas de nuestra cultura, puedan ser decodificados o reestructurados en narrativas que hablan, cuentan y referencian historias; lo que nos permite exponer o interpretar las relaciones, visiones e interrogantes de los espacios educativos.

Professional Emotional Readiness in Future Journalists at Different Stages of University Education
Authors: Dzvonik V. P.
Published: December 2022

Emotional readiness plays an important role in the general structure of psychological readiness for professional activity. This article provides a theoretical substantiation of the place that emotional readiness occupies in the structure of psychological readiness. Professional emotional readiness includes emotional awareness, coping with one’s own emotions and with those of others, empathy, and self-motivation. The research revealed various emotional manifestations of psychological readiness in university students that majored in journalism at different years of study. The study included an experiment that proved the beneficial impact of student journalism as part of academic and extracurricular media projects, especially those connected with filming. The undergraduates that participated in such activities proved able to cope with emotions and demonstrated a better emotional awareness and empathy. However, they proved unable to cope with other people’s emotions and had a low self-motivation. These problems might be associated with insufficient life and professional experience. Therefore, the emotional development of future journalists requires a comprehensive program of psychological and pedagogical support at different stages of university education. Such an approach may help students to interpret and control their own emotional state, as well as to build effective communicative strategies for interpersonal communication.
Geospatial Data Acquisition Using Unmanned Aerial Systems (Uas)
Authors: AMINIGBO LEONARD MICHAEL ONYINYECHI , BROWN JOSHUA , EDE PRECIOUS
Published: December 2022

The Rivers State University campus in Portharcourt is one of the university campuses in the city of Portharcourt, Nigeria covering over 21 square kilometers and housing a variety of academic, residential, administrative and other support buildings. The University Campus has seen significant transformation in recent years, including the rehabilitation of old facilities, the construction of new academic facilities and the most recent update on the creation of new collages, faculties and departments. The current view of the transformations done within the University Campus is missing from several available maps of the university. Numerous facilities have been constructed on the University Campus that are not represented on these maps as well as the qualities associated with these facilities. Existing information on the various landscapes on the map is outdated and it needs to be streamlined in light of recent changes to the University's facilities and departments. This research article aims to demonstrate the effectiveness of unmanned aerial systems (UAS) in geospatial data collection for physical planning and mapping of infrastructures at the Rivers State University Port Harcourt campus by developing a UAS-based digital map and tour guide for RSU's main campus covering all collages, faculties and departments and this offers visitors, staff and students with location and attribute information within the campus.Methodologically, Unmanned Aerial Vehicles were deployed to obtain current visible images of the campus following the growth and increasing infrastructural development. At a flying height of 76.2m (250 ft), a DJI Phantom 4 Pro UAS equipped with a 20-megapixel visible camera was flown around the campus, generating imagery with 1.69cm spatial resolution per pixel. To obtain 3D modeling capabilities, visible imagery was acquired using the flight-planning software DroneDeploy with a near nadir angle and 75 percent front and side overlap.Vertical positions were linked to the World Geodetic System 1984 and horizontal positions to the 1984 World Geodetic Datum universal transverse Mercator (UTM) (WGS 84). To match the UAS data, GCPs were transformed to UTM zone 32 north.Finally, dense point clouds, DSM, and an orthomosaic which is a geometrically corrected aerial image that provides an accurate representation of an area and can be used to determine true distances, were among the UAS-derived deliverables.Keywords; UAS, Geospatial, Acquisition, Orthophoto, Mosaic, Flying –Height.
Development Plan for decreasing crime Rates at El Amir Hamad Archeological Site
Authors: HATEM YASMIN MOANIS
Published: December 2022

Recently, the direct causal relationship between the built environment and well-being has been shown to affect the quality of life as well as the performance of the urban environment. While it is often difficult to establish, the urban built environment plays a major role in shaping the way people act inside it. (Thwaites, Kevin, et al., 2016)
While urbanisation takes place in a transforming society, societal development leaves its signature in urban spaces. When industries and development plans decline in some parts of the city, especially those with archaeological value, those parts will have been abandoned due to migration. Urban pockets or gaps inside the built environment are left behind to suffer from informality, deterioration, and increasing crime and unemployment rates.
The aim of that research is to find some possible solutions in the direction of improving those public abandoned spaces that accommodate dangerous buildings, high rates of unemployment and unsafe urban areas in the regional range of Meet-Ghamr, Dakhlia governorate. (Aggnieszka Lisowska, 2017).
The targeted area of the study is "minaret el Amir Hamaad" in Meet-Ghamr, Dakahleia, Egypt, one of the most important archaeological sites in the Islamic heritage of Dakhlia governorate, which is well known for its unique mosques and mosque minarets.
Connecting cities across infrastructural divides
Authors: Devenish Paul
Published: December 2022

This paper investigates opportunities to connect divided cities by analysing ways in which occupation practices operate alongside, subvert and potentially transform historic, and presently developing urban infrastructure divisions in Tshwane’s eastern urban region. Through a critical theory lens existing and perpetuating conditions of infrastructural segregation are examined in order to understand scenarios through which built environments, as assemblages, maintain conditions of extreme inequality and power. In this respect, urban spatial research projects, analysing formal and informal settlement patterns are presented. The projects form part of an architecture design lead research studio that focuses on discovering alternative scenarios for urban environments by examining existing infrastructure barriers, and unpacking methods for the transformation of segregative systemic forms. Extracts of the projects are presented as case studies with a focus on areas around Mamelodi east and Moreleta Park in rapidly growing parts of Tshwane. These projects demonstrate conditions through which urban divisions of scarcity are established and constructed along infrastructure development zones in the region. They also raise key spatial questions pertaining to inequality and the role of capital investment in its perpetuation. 
The second part of the project involves socio-spatial methods of mapping self-build situations occurring alongside hard infrastructure zones in the region. The studies focus on the composition of building fabrics that actively attempt to circumvent issues of scarcity and unequal access to material and social infrastructures. Through the establishment of physical interfaces, people form modes of operation despite extreme resource limitations. The project aims to identify alternative ways of reading territorialised urban infrastructure assemblages by examining critical zones of urban occupation. While the examples expose many of the volatile situations that the urban majority experience on a perpetual basis, the primary aim is to reveal - from the everyday – urban spatial emergence and methods of coding and mapping these emergences towards an adaptive, reparative and transformative approach to divided cities.
Brownfield land redevelopment strategies in urban areas
Authors: Singh Sukhjap , Kiroff Lydia , Sharma Rashika
Published: December 2022

Urban intensification seems to be a growing trend, especially in the context of severe land scarcity. Brownfields offer great potential in meeting the increasing demand for housing in major cities worldwide. Redevelopment projects appear to provide immediate solutions to housing shortages that are being experienced due to population pressures in large metropolitan areas. The paper explores the range of factors that property developers need to consider in their decision-making process when assessing the viability of brownfield redevelopments. This research, which employed a comparative case study approach, and examined two brownfield redevelopments in Auckland, focused on the economic, social, and environmental criteria that were utilised in the decision-making process. Document analysis of the two case studies, site observations, and semi-structured interviews with the property developers were the main data collection methods. The results suggested that the economic aspects of a brownfield redevelopment are the most important criteria that developers consider during the feasibility assessment of proposed projects. Projects that offer the potential for quick investment returns for all stakeholders are the preferred choice for developers. Brownfield redevelopments offer significant potential for invigorating local areas through urban intensification which boosts local businesses and encourages community revitalisation. The environmental concerns appear to be the lowest priority and little consideration is given to reducing the environmental impacts or incorporating green building practices in the new developments. A major shift from a purely economic focus toward a comprehensive environmental approach to new developments is needed to ensure the sustainable development of cities.

Penelitian ini bertujuan untuk mengetahui pengaruh waktu dan konsentrasi ozon terhadap residu mankozeb buah melon fresh-cut. Memberikan penanganan yang baik dari segi kualitas pada buah melon fresh-cut menggunakan metode ozonated water dan untuk mengetahui jenis mikroba yang ada pada buah melon fresh-cut. Metodologi penelitian menggunakan analisis regresi linear berganda dengan bantuan software minitab 2016 dengan perlakuan pada konsentrasi larutan ozon 1.6 ppm, 0.8 ppm, 0.4 ppm, waktu perendaman 10 menit dan 20 menit, serta masa simpan pada suhu kamar selama 3 hari dan 5 hari, dengan 3 kali ulangan. Parameter dalam penelitian adalah kadar residu pestisida dan identifikasi mikroba dengan 16S rRNA. Hasil penelitian dapat ditarik kesimpulan bahwa penggunaan ozonasi pada berbagai kadar ppm tidak menunjukkan hasil yang berbeda nyata terhadap residu Mankozeb, tetapi berbeda nyata dengan kontrol (tanpa ozonasi) dan hasil identifikasi mikroba menunjukkan hasil galur Kocuria rhizophila (gram positif) sangat mendominasi buah melon fresh-cut karena resistensi jamur dari bahan aktif pestisida sehingga dapat menyebabkan kualitas buah menurun dan buah mudah terkontaminasi oleh mikroba.

Concern on rice production in Indonesia is escalating since the production of rice tends to be levelling off for more than a decade. Soil degradation in lowland is among the main challenges. Soil encounters continuous decreasing organic matter and organic carbon content because the biomass from the rice plants was not returned to the land sufficiently. Most of the biomasses went out of the land or were burned by rice producers since there was not enough time to decompose the biomass before returning into the soil of lowland or it need additional cost to do so. Most farmers preferred to return the rice straw after burning, but it will not improve the condition. Otherwise, burning of rice straw caused air pollution since it released at least three kg particulate matter consisting of CO, SO2, CO2, and ash. Using interpretive structural modeling (ISM) this paper is trying to find the important factors with sequential solution. The result shows that encouraging rice producers to return rice straw into soil (RRIS) should start with Provision of Immediate Decomposing Technology and assistance program and Credit and Assistance Program.

One of the major hallmarks of many cancer cells is dedifferentiated cells (immature cells) with little or no resemblance to normal cells. Besides the poor differentiation, malignant cells also have important features such as aggressiveness and resistance to different therapeutics. Differentiation potentiators hold great promise for cancer treatment. Dimethyl sulfoxide (DMSO) is a well-characterized pharmaceutical solvent. It is used as a component of numerous cancer therapeutic approaches, including cancer treatment and several approved cancer immune therapeutics such as Car-T cell therapy and the FDA-approved drug Mekinist (trametinib DMSO) for melanoma treatment. It is also biologically recognized as a pharmaceutical solvent and cryoprotectant. In the current literature, there are no mentions of DMSO’s possible ability to potentiate therapeutic activity as a component of these cancer treatments. This review aimed to summarize scientific evidence and substantiate the concept that DMSO can contribute positively to the overall efficacy of cancer treatment as an adjuvant that is safe, inexpensive, and an effective differentiation-inducing therapeutic agent.

Background: Intravascular large B-cell lymphoma (IVLBCL) is a rare subtype of extranodal B-cell lymphoma, which has traditionally been associated with poor outcomes. Despite increasing recognition, IVLBCL requires a high degree of clinical suspicion on the part of the clinician for its diagnosis. Case Series: We present four patient cases: A 69-year-old female with constitutional symptoms and cognitive decline; a 78-year-old female with kidney injury and constitutional symptoms whose disease rapidly progressed to multiorgan failure and death; a 70-year-old asymptomatic female with an incidentally found, enlarged thyroid; and a 63-year-old male with cytopenia and constitutional symptoms. Retrospective chart analysis was performed on these four patients diagnosed with IVLBCL at our Institute to identify the pathognomonic features of the disease and compare these to the published evidence. IVLBCL has a heterogeneous presentation, as seen in our four patients. The disease is characterized by the exclusive presence of malignant cells inside the blood vessels and lack of organ infiltration. Traditional preliminary diagnostic modalities such as imaging are usually inconclusive, given the paucity of lymphomatous aggregates. A bone marrow biopsy, random skin biopsies, or a focal organ biopsy in appropriate cases is required for diagnosis. Immunosuppression might play a role in the pathogenesis. Timely initiation of aggressive cancer-directed therapy was associated with improved outcomes. Monitoring for disease response and relapse continues to be a challenge. Conclusion: Our mini-series highlights the significance of timely diagnosis and intervention in IVLBCL and emphasizes the importance of further research to determine its association with immunosuppression.

Background/Aim: In advanced stage lung cancer, bulky tumors can cause serious symptoms such as malignant airway obstruction (MAO). Prompt response to airway obstruction might be essential to improve quality of life and prolong life expectancy. Palliative external beam radiotherapy (EBRT) is a less invasive and highly safe treatment method that can alleviate symptoms and at the same time treat lung cancer. However, there are few reports on the results of palliative radiotherapy performed for improving airway obstruction and obstructive pneumonia. Therefore, this study retrospectively examined the effectiveness of palliative radiotherapy. Patients and Methods: We reviewed 38 lung cancer patients with MAO who underwent EBRT. Patients were treated with a median dose of 37.5 Gy (range=30-40 Gy) in 10-20 fractions. Whether a patient was a responder or non-responder was assessed by whether the bronchus that was obstructed before EBRT reopened or improvement of obstructive pneumonia was observed on follow-up chest X-ray or computed tomography after EBRT. Results: The median survival time was 135 days (range=31-469 days) for the responders to EBRT and 45 days (range=23-355 days) for non-responders; this difference was statistically significant (p=0.03). One-year overall survival rate was 18.5% and 0% for the responders to EBRT and non-responders, respectively. Conclusion: Palliative EBRT might be an important option for non-curative lung cancer patients with MAO.
