Thermal insulating property of an optically-active polyurethane-based silicon aerogel
Authors: Lin Ling , Wang Chaoxia
Published: March 2021

Improving the mechanical property of the silicon aerogel while maintaining its excellent thermal insulation performance is still a big challenge in developing the next-generation thermal insulation materials. To solve this problem, the optically active polyurethane aerogel composite is developed via the sol-gel method to combine the advantages of the thermal insulation performance of the silicon aerogel and the mechanical property of the end-capped siloxane optically-active polyurethane. The prepared composite is characterized by the SEM, the Fourier transform infrared spectroscopy, the absorption-desorption curve, the thermal analysis, and the mechanical property. Results show that the composite has intact pores with high surface area and pore volume, leading to excellent thermal insulation and mechanical performance. Moreover, its thermal insulation performance is greatly enhanced due to the better distributed small pores and the thermal reflective effect of binaphthyl groups which collaboratively block heat loss from thermal conduction and thermal radiation. The thermal stability is similar to silicon aerogel and its heat resistance temperature is 445?. The addition of macromolecular polymers increases the contact points between particles, the contact areas between particles of the network skeletons, and the supporting effect of the skeleton material, which ensures the stability of the material structure. The compressive modulus of prepared composite is up to 2.465 MPa, which is 600 times more than that of the pure SiO2 aerogels.
IGNORANCE AND INQUIRY
Authors: Pritchard Duncan
Published: March 2021

It is argued that the two main accounts of ignorance in the contemporary literature—in the terms of the lack of knowledge and the lack of true belief—are lacking in key respects. A new way of thinking about ignorance is offered that can accommodate the motivations for both of the standard views, but which in the process also avoids the problems that afflict these proposals. In short, this new account of ignorance incorporates the idea that ignorance essentially involves not just the absence of a certain epistemic good, but also an intellectual failing of inquiry. It is further contended that making sense of this normative dimension to ignorance requires one to situate one’s account of ignorance within a wider epistemic axiology.

Published: March 2021

Proper blade design, selection and use continue to gain importance with the developing technology, aviation and space industry. Many applications use wings such as aircraft (planes, helicopters, etc.), UAV (Unmanned Aerial Vehicle), wind turbines and so on. This study covers a NACA 0009 profiled wing with a 111 mm span and chord and its CFD analysis using Ansys version 15.0. Three-dimensional analysis has been done using Ansys Fluent. A geometry was created, this geometry was meshed properly, tighter especially close to the wings, and its analysis was completed using the k-w turbulence model. In total 2,078,272 nodes and 2,036,295 elements have been formed in the mesh. Four different angles of attack have been tested which are 0°, 5°, 10° and 15° at 37,000 Reynolds number. Generated mesh has an average skewness rate of 1.3 and an average orthogonal quality rate of 0.97. Velocity contours and streamlines have been compared to the literature. Lift and drag coefficients have been monitored. As the angle of attack increases, it is seen that shocks form at the trailing edge especially at 15° angle of attack and therefore aerodynamic performance of the NACA 0009 at different angles has been tested. With a L/D ratio of 10.03, the 5° angle of attack have been prevailed in comparisons.

Corrosion is the deterioration of a substance (usually a metal) or its properties because of the reaction with its environment. There are many forms of corrosion, some of which are encountered in everyday life. Direct losses due to corrosion are more than $276 billion dollars annually = 3.1% of Gross Domestic Product only in the United States. If we consider the rest of the world this figure would be many times higher. However, corrosion and its control besides of its importance, is often a neglected element in the practice of engineering. This work presents the design of an innovative low cost device to carry out corrosion testing of materials in different environments. High costs that result from the fabrication of special probes or devices for testing, make it an interesting challenge for the engineer or designer. This original and innovative device has been designed accordingly to both the laboratory equipment which will do the characterization and assessment of the corrosion testing, as well as the “Loop reactor” where testing will be carried out in different environments.

Published: March 2021

Aim. To assess the age-related cancer incidence in Omsk and Orenburg Regions.

Materials and Methods. We analysed the statistical reports (form 7) obtained from the health authorities of Omsk and Orenburg Regions from 2010 to 2019.

Results. Age-specific indicators of cancer incidence in the indicated regions differed significantly (р < 0.001). In the Omsk Region, cancer incidence showed a 65-fold increase with age (from 20 to 79 years), reaching the maximum values at the age of 75-79 years and then decreasing in subjects > 80 years of age (p < 0.05). In the Orenburg region, age-related incidence rates increased 95-fold from 20 to 79 years, reaching a maximum level in the age group of 70-79 years, that was also followed by a decrease in the population over 80 years of age (p < 0.05). Trends in cancer incidence in Omsk and Orenburg Regions were similar to those in Russia, yet the rate was 1.4-1.8-fold lower. Cancer incidence in both regions had a moderate upward trend (increment of 1.2% and 1.5%, respectively; p < 0.001). The highest increase in cancer incidence was detected in subjects between 30 and 39 years and over 80 years of age (Omsk and Orenburg Regions, increment of 1.4% and 2.5%; 1.3% and 1.3%, respectively; p < 0.001).

Conclusions. Cancer incidence in the Orenburg Region significantly exceeds that in the Omsk region, yet both of the regions are characterised by the specific trends. We found the most significant increase in cancer incidence in subjects > 80 years of age over the last decade, which was more pronounced in the Omsk Region in comparison with the Orenburg Region.

Aim. To study the trends in the prevalence of respiratory tract infections in the population of Kemerovo Region and to interrogate the particulate matter as a possible route for the transmission of multidrug-resistant microorganisms into medical organisations.

Materials and Methods. We investigated the prevalence of acute respiratory infections and community-acquired pneumonia among the population of Kuzbass (Kemerovo Region) according to the offcial medical records collected from 2004 to 2020. The study included 10,320,384 cases of acute respiratory infections, 145,357 cases of community-acquired pneumonia, 344,703 hospitalisations of the adults (subjects ≥ 18 years of age) and 75,041 hospitalisations of children (< 18 years of age). Collection of particulate matter samples (n = 97) was performed using sterile gloves and containers from ventilation grilles and adjacent air ducts of the exhaust ventilation systems in various healthcare settings. Bacterial composition of the dust was examined using a VITEK 2 Compact biochemical analyzer. Viral diversity was screened by polymerase chain reaction.

Results. Over the study period, respiratory infections were common in Kemerovo Region (average prevalence 22,155.9 per 100,000 population) and showed an increasing incidence. Frequency of respiratory infections among the hospitalised patients was 207.14 per 1,000, being 1.63-fold higher in children than in adults (304.15 and 186.02, respectively). In 2020, the proportion of cefotaxime-resistant Klebsiella spp. was 26.20% that was strikingly high compared to 2019. Hospital particulate matter frequently (71.13% samples) harboured multidrug-resistant microorganisms.

Conclusions. High prevalence and morbidity from respiratory infections in Kemerovo Region are combined with high prevalence and biodiversity of airborne microorganisms, in particular multidrug-resistant microbes contaminating the hospital particulate matter.

Turkish universities are not among the top 500 universities in most of the world university ranking systems and have had difficulties in maintaining their current place for the last five years. The most important reason for this decline is that they cannot produce high-quality research outcome. In the literature of higher education studies, there are a limited number of studies on how state universities governed with solely public resources could follow "research-oriented strategies and policies" and what they should do in concrete terms. Based on this deficiency, in this study, experiences of the Research Development and Coordination Board (RDCB) which was established to apply the strategies of Akdeniz University to become a research-oriented university effectively and sustainably, to adapt quickly to the newly formed and developing conditions in the field of R&D, to develop strategies, and to contribute to the university's capacity at the highest level to produce qualified scientific knowledge were examined. Thus, how the institutionalization of the research-oriented university was ensured, the practices that could and could not be realized accordingly with the established policy goals, and the effects of 2017-2020 policies on research outcomes were discussed in detail. The study, in particular, provides important information on how to improve research outcomes through public research budget and which roles the board can play in improving research outcome.
A Solution to Frequency Splitting in Magnetic Resonance Wireless Power Transfer Systems Using Double Sided Symmetric Capacitors
Authors: Thabet Thabat , Woods John
Published: March 2021

The technology of wireless power transfer using magnetic resonance coupling has become a subject of interest for researchers with the proliferation of mobile. The maximum efficiency is achieved at a specific gap between the resonators in the system. However, the resonance frequency splits as the gap declines or gets smaller. Different methods have been studied to improve this such as frequency tracking and impedance matching, including capacitive tuning. However, the system has to maintain the same working frequency to avoid moving out of the license exempt industrial, scientific, and medical (ISM) band; and the efficiency must be as large as possible. In this paper, a symmetric capacitance tuning method is presented to achieve these two conditions and solve the splitting problem. In the proposed method, the maximum efficiency at one of the splitting frequencies is moved to match the original resonance frequency. By comparison to other works, both simulation and experiment show considerable improvements for the proposed method over existing frequency tracking and impedance matching methods. The paper also presents a proposal to apply this method automatically which can achieve wireless charging for electronic applications with high efficiency and through variable distance.
Parallel and Series Connection of Dark Electric Current in Liquid and Second Law of Thermodynamics
Authors: Gerasimov Sergey A.
Published: March 2021

Liquid in contact with two asymmetrical spiral-shape aluminum electrodes behaves like a still weak source of electrical energy. Almost the only way to increase the efficiency of such a source of electrical energy is to reduce internal resistance. Reducing internal resistance is equivalent to using multiple sources of electrical energy connected in series or in parallel. To check this for such unusual sources it is first necessary to study the properties of each source, which is the voltage drop across the load resistance and the internal resistance of each source. Detailed analysis of experimental data shows that the process of forming the dark current is different from a chemical one.
Positioning the Portrayal of White Protagonists in O.A Bushnell’s the Return of Lono and Ka’a’awa
Authors: Indriyanto Kristiawan , Adi Ida Rochani , Rokhman Muh. Arif
Published: March 2021

This paper explores the role of literature in the post-truth age through reading on O.A Bushnell’s the Return of Lono and Ka’a’awa. A Hawai’ian novelist, Bushnell contextualizes the earliest interactions between the native Hawai’ian (Kanaka Maoli) and the white settlers which began with the arrival of Captain Cook’s expedition in 1778. Through his fictions, Bushnell underlines positive portrayal of the white characters to provide a counter-discourse to the generally accepted history of Hawai’ian colonialism. Through first person point of view, white characters become the central figure in both of Bushnell’s fictions. Through reading on O.A Bushnell’s narration, this paper aims to elaborate how the Hawai’ian natives also become a willing partner in western colonialism which highlights their colonial complicity. The concept of colonial complicity is employed to highlight the participation of the natives in promoting Western way of thinking. The analysis argues that although Bushnell contextualizes the complicity of the Hawai’ians in promoting Western discourse, resistance also occurs through creation of a hybrid culture.  This paper concludes that in the post truth era, literature should always strive to uncover the truth based on subjective interpretation instead of abiding of a universal truth.
Indonesian Woman Migrant Workers Fighting Inequality and Violence in Burung-Burung Migran
Authors: Agustina Hiqma Nur
Published: March 2021

The story of Indonesian Migrant Workers or Tenaga Kerja Indonesia (TKI) is a blurred portrait of Indonesian citizens' absence in their own country, presented in Burung-burung Migran by Miranda Harlan. This study aims to expose gender inequality, the dominance of structural oppression systems, and poor treatment of woman migrant workers. They struggle to get out of poverty, unemployed, unskilled, and uneducated. The determination and willingness to change destiny is not in line with the reality that often does not side with them. This study uses a qualitative method, narrative strategies about narrator, and focalizations, and gender concepts. The results showed that the focalization and narrator type in the text are internal focalisator and homodiegetic narrator. The focalisator also shows unequal gender relations, physical and verbal violence, which tends to repress Indonesian woman migrant workers. The writer's narrative strategy is in the form of using words, phrases, and sentences that appropriately reflect the repression of female migrant workers.
The Study of Reduplication and Retriplication in the Yoruba Language
Authors: Friday-Otun Joseph Omoniyi
Published: March 2021

The Yoruba language, a regional lingua franca in Nigeria, which belongs to the Kwa sub-family of Kordofanian phylum of the larger African language family, is spoken in Nigeria, Togo, Ghana, Liberia, Brazil, Cuba, etc. The language attests a very productive feature of reduplication which has attracted the attention of many scholars. But its extended form, tagged, “retriplication” in this paper, remains largely unexplored. This study examines the form and functions of reduplication and retriplication which are two morphological processes where the former serves as a pedestal to the latter. While applying the participant observation method to elicit data from main Yoruba cities in Nigeria, the Pulleyblank (2009) model, as well as the descriptive and context usage approaches are employed to analyse and discuss the data. The study reveals that while reduplication process actualises intensification, nominalisation, emphasis and comparative qualifying, retriplication serves for more intensification, wider nominalisation, more emphasis and superlative qualifying. The research further reveals that, while all cases of verb and adjective reduplicates can be retriplicated without generating unacceptable utterances in Yoruba, the gerundive reduplicates cannot culminate in retriplication. However, kinship reduplicate allows retriplication when stretched to the third generation.  The paper concludes by calling for more study on retriplication in other languages of the world, particularly, African and Asian languages that massively exhibit the two phenomena.
The Metaphoric Conceptualization of the Covid-19 Pandemic in the Online Press Releases of Lapor Covid-19 and Kominfo
Authors: Wardani Maria Magdalena Sinta
Published: March 2021

This article seeks to describe the metaphoric conceptualization of the COVID-19 pandemic in the online press releases of Lapor COVID-19 and the Ministry of Communication and Information Technology (Kominfo). More specifically, it seeks to 1) describe the metaphorical linguistic forms contained in the online press releases of Lapor COVID-19 and Kominfo, 2) identify the conceptual metaphors contained in the online press releases of Lapor COVID-19 and Kominfo, 3) describe the function of the metaphors contained in the online press releases of Lapor COVID-19 and Kominfo. Data were collected between March 1 and October 31, 2020. Analysis was conducted using the method developed by Steen (2009). Nine metaphors were identified as being used within the context of the COVID-19 pandemic: 1) berguguran ('fall in battle'), 2) berdamai ('make peace'), 3) garis depan ('frontlines'), 4) melawan ('oppose'), 5) menang ('win'), 6) benteng ('fortress, bastion'), 7) menghantui ('spook'), 8) membesar ('grow in size'), and 9) menelan ('swallow'). Three conceptual metaphorizations of the pandemic were utilized by Lapor COVID-19, namely 1) PANDEMIC IS WAR, 2) PANDEMIC IS GHOST/SPECTER, and 3) PANDEMIC IS MONSTER. Meanwhile, one conceptual metaphorization was identified in Kominfo's press releases: PANDEMIC IS WAR. These conceptual metaphors' selection was informed by the genre of the discourses as well as specific characteristics of the institutional. Metaphors, as rhetoric devices in persuasive discourses, function to 1) increase the attractiveness of the message and stimulate readers' imagination, 2) reduce the complexity of the message, and 3) to concretize the discourse.
Worms, worms, everywhere, and not a one to see: The connotative role of worms in Shakespeare’s canon
Authors:   , Reid Christine
Published: March 2021

The study of animals in Shakespeare’s collected works has expanded over the last 30 years. While a number of different animals have been discussed, the importance of the worm in the larger scope of the canon has largely been ignored. By focusing on the perception and presentation of worms in relation to cultural ideas of death, corruption, and consumption, ideas surrounding the body and soul are brought to the forefront. Worms are integral to our understanding of the Early Modern cultural constructs of the body and soul as the presence of worms reveals the state of the individual or the broader environment. Overall, the depiction of worms in Shakespeare’s works serves as a way to understand the metaphysical processes surrounding death and corruption.

Günümüzde insan ve çevre sağlığını tehdit eden en önemli problemlerin başında hava kirliliği gelmektedir. Hava kirliliğinin pek çok bileşeni bulunmakla birlikte, bunlar arasında ağır metaller ayrı bir öneme sahiptir. Bunun sebebi ağır metallerin bazılarının düşük konsantrasyonlarda bile toksik olmaları, canlılar için besin elementi olan birçok ağır metalin bile yüksek konsantrasyonlarda zararlı olmaları, canlı bünyesinde biyobirikme eğiliminde olmaları, doğada kolay kolay bozulmamaları ve bunlara ek olarak sanayi ve trafik kaynaklı olarak havadaki konsantrasyonlarının sürekli artmasıdır. Bundan dolayı özellikle trafiğin yoğun olduğu, sanayi faaliyetlerinin yürütüldüğü ve nüfusun yoğun olduğu alanlar gibi riskli alanlarda havadaki ağır metal konsantrasyonlarının izlenmesi büyük önem taşımaktadır. Bu çalışmada da, Samsun kent merkezinde yetiştirilen ve peyzaj çalışmalarında sıklıkla kullanılan; Tilia tomentosa, Aesculus hippocastanum, Ligustrum vulgare ve Catalpa bignoides türlerinin, trafiğin yoğun olduğu, az yoğun olduğu ve hemen hemen hiç olmadığı alanlarda yetişen bireylerinde Cr konsatrasyonlarının değişimleri belirlenmeye çalışılmıştır. Çalışma kapsamında bitkilerden yaprak, kabuk ve odun örnekleri toplanmış, kabuk ve yapraklarda ayrıca yıkama işlemi uygulaması da yapılmıştır. Çalışma sonucunda, çalışmaya konu türlerde Cr konsantrasyonlarının tür, organ ve trafik yoğunluğu bazında önemli ölçüde değiştiği belirlenmiştir.

Bu çalışma, Tokat/Erbaa ve Tokat/Kazova lokasyonlarında tarla koşullarında 2017 yılında topraktan artan dozlarda (0, 3, 6 ve 9 kg da-1) MgSO4 uygulamalarının Xanthi 81 tütün çeşidinin yaprak verimi, kalitesi ile yaprağın bazı kimyasal (Mg, S, N, K, P, nikotin, şeker, klorogenik ve rutin konsantrasyonu) içeriklerine etkisi araştırılmıştır. Araştırma tesadüf blokları deneme desenine göre üç tekerrürlü olarak kurulmuş olup, hasat olgunluğuna gelen yapraklar üç elde hasat edilmiştir. Elde edilen sonuçlara göre, artan dozlarda MgSO4 uygulaması ile Erbaa ve Kazova lokasyonlarında yetiştirilen tütün çeşidinin yaprak veriminde artışlar meydana gelmiştir. Yaprak veriminde ortaya çıkan artış en fazla MgSO4‘ın 6 kg da-1 dozunda görülmüş ve bu artış Erbaa lokasyonunda %22, Kazova lokasyonunda ise %6,4 düzeyinde olmuştur. Artan MgSO4 uygulamaları ile yaprak Mg ve S konsantrasyonlarında istatiksel olarak önemli artışlara neden olduğu, en fazla artışın yaprak veriminde olduğu gibi MgSO4‘ın 6 kg da-1 dozunda olduğu görülmüştür. Tütün için çok önemli bir alkaloid bileşeni olan nikotin konsantrasyonu MgSO4 uygulaması ile her iki lokasyonda da azalmıştır. Sonuçlar, artan dozlarda MgSO4 uygulamalarının tütün yaprağının veriminde artışa neden olduğu, yaprak Mg ve S konsantrasyonlarında artışa, nikotin konsantrasyonlarında ise azalmaya neden olduğu ortaya çıkmıştır.

Buddleja madagascariensis Lam. is a perennial invasive shrub distributed in tropical and sub-tropical regions of the world. The present study was conducted on morphological, anatomical and phytochemical characterization of Buddleja madagascariensis and the results revealed that plant height varied from about 188-191 cm, and the whole plant was covered with trichome which may be glandular and eglandular and unicellular or, multicellular. Inflorescence was terminal and axillary in position, thyrsoid panicle. Anatomical and histo-chemical studies of the transverse section of various parts of the plant revealed the presence of steller tissues, starch in cortical and pith region. Phytochemical analysis of the crude extract showed the presence of carbohydrates, proteins, saponins, flavonoids, phenolic compounds and tannins. But alkaloids, glycosides and free amino acids were absent. Thus, characterization of plants on the basis of these parameters could be used as tools to distinguish the crude drugs of plants from adulterants, used in the preparation of traditional medicines and used as diagnostic keys. Also, it is useful in the future for revealing the importance of plants and phytochemical resources for the conservation of resources.

The aim of this study was to find a suitable treatment combination that would effectively induce polyploidy in Coriander. In this study, colchicine concentrations and treatment durations were examined for improving the induction of polyploidy. The combinations of three colchicine concentrations such as 0.1%, 0.2% and 0.3% for 3 hrs per day for two to three days were tested in coriander. Three tetraploids were obtained in 0.2% colchicine treated population. The treatment of colchicine (cotton swab method) seedling with 0.2% for 3 days was suitable for induction of chromosome doubling. The control plant showed eleven bivalents (2n=2x=22) and polyploid plant showed twenty two bivalents (2n=4x=44) at diakinesis/metaphase-I in most of the PMCs. Anaphase-I distribution of chromosomes was normal (11:11) in control and in tetraploids distribution of chromosomes was (22:22) at each poles. In contrast with the normal plants, those treated by colchicine treatment often showed changes in height and width, in thickness of branches, in size, shape, texture of leaves, flowers, size of fruits and seed setting.

COVID 19, which has lead to the death of millions of people, is still spreading worldwide. The development of any new drug after proper trial is much time consuming.  This present global pandemic situation has lead the researchers around the world to run behind various existing antiviral and immunomodulatory natural compounds to overcome this contagious disease.  Withania somnifera (ashwagandha) that is being used in Ayurvedic medicine for several ailments since several years is also said to pocess anti viral activity. Thus many of its metabolites are being studied individually for its efficacy against the dreadful disease. Withaferin A, a steroidal lactone from ashwagandha is one such prime metabolite which beyond acting as an antioxidant or antimicrobial agent, is also said to pocess anti-inflammatory to anti carcinogenic properties.  Thus because of its wide spectrum of medicinal properties it has now become an attractive drug candidate for several preclinical studies. This increase in the demand for withaferin A has chanelled its way towards in vitro propagation of the plant Withania somnifera and trials on various strategies to increase the yield in terms of plant biomass as well as the withaferin content in the plants thus making it a better alternative to field grown plants. Thus this article reviews in depth on the important medicinal properties of withaferin A, its demand in Ayurveda industry and the in vitro strategies being carried out to overcome the demand.
Autonomous Delay Tolerant Network Management Using Reinforcement Learning
Authors: Buzzi Pau Garcia , Selva Daniel , Net Marc Sanchez
Published: March 2021

Delay tolerant networks (DTNs) offer a set of standardized protocols to enable Internet-like connectivity across the solar system. Unlike other protocols such as the Transmission Control Protocol (TCP) and the Internet Protocol (IP), DTN protocols are robust to end-to-end connection disruptions and long delays. Although the behavior of DTN core protocols is well understood, management of DTNs is still an area of active research. This paper uses reinforcement learning (RL) to automate the management of a DTN node consisting of an orbital relay between the moon and Earth. More specifically, the RL agent is in charge of deciding when to drop packets, when to change the data rate of the neighbor node links, when to reroute bundles to crosslinks, or when not to change any network parameter. The agent’s goal is to maximize the bits received by the Deep Space Network while minimizing the capacity allocated to all controlled links, and control the buffer utilization to avoid memory overflows. To assess the potential of using RL in DTN management, the performance of the trained RL agent is benchmarked against other non-RL-based policies in a realistic lunar scenario. Results show that the RL agent provides the highest reward, outperforming all non-RL policies in this scenario.
