Authors: Bykov V. N. , Miroshnik G. Yu. , Miroshnik T. V.
Published: October 2022

Background: The use of passive matrix radiometric sensors of the millimeter wave range in aircraft navigation systems, which make it possible to form a radiometric image of a ground navigation object under conditions of high-speed flight of aircraft, is one of the effective ways to ensure high accuracy in measuring the coordinates of objects and, ultimately, leads to an increase in the probability of positioning aircraft [1]. In work [2], analytical relationships were obtained and quantitative estimates of the accuracy of positioning of aircraft equipped with a matrix radiometric navigation system were made. It is shown that the use of matrix radiometric sensors makes it possible to realize the required high (up to units - tens of meters) positioning accuracy of high-speed aircraft.

Objectives: The purpose of this article is to develop a method for increasing the accuracy of a radiometric correlation - extreme system based on the use of a matrix radiometric millimeter-wave receiver with channel compaction.

Materials and methods: In this paper, we used the method of linear multiplexing with channel separation according to the waveform using orthogonal Walsh functions. In this case, the sensitivity for each channel corresponds to the sensitivity of the modulation radiometer, and in comparison with the sensitivity of the compensation radiometer, it decreases by about two times. Taking into account the orthonormality of the Walsh functions, the signal at the output of each channel is proportional to the intensity (power) of the signal at the input of this channel.

Results: In this work, it is shown that the optimal number of combined channels is a multiple . The analysis of the results of the calculations shows that the combination of 64 channels into one amplifier-conversion path leads to an increase in inter-channel interference and, as a consequence, to a deterioration in the sensitivity of each channel.

Conclusions: In this case, it is expedient to limit the number of channels to be sealed per one amplifying-converting path. So, when 16 channels are combined into one path, the sensitivity of each channel remains quite high: about 1 K – for a super heterodyne radiometric receiver, and less than 1 K – for a direct amplification radiometric receiver. In this case, the number of amplifying-conversion paths with the total number of channels in the matrix 64 is equal to four.
Optimization of the number of channels of a multichannel radiometric receiver
Authors: Bykov V. N. , Miroshnik G. Yu. , Miroshnik T. V.
Published: October 2022

Background: Improving the positioning accuracy of passive radiometric correlation-extreme navigation systems (RM CENS) of aircraft (AC) by landmarks depends on the ability of information RM sensors of systems to form two-dimensional images of ground objects in real time. The use of matrix RM sensors, which are based on multichannel RM receivers of the millimeter wave range (MMW), makes it possible to realize the required speed of the CENS

Objectives: The aim of the work is to optimize the number of multiplexed channels per one amplifying-converting path of a multi-channel RM receiver with linear multiplexing and separation of channels according to the form of signals.

Materials and methods: As an optimization criterion in this work, it is proposed to use the gain in sensitivity obtained as a result of the use of a multichannel RM receiver with linear multiplexing and signal waveform separation in comparison with the sensitivity of a RM receiver with time division multiplexing.

Results: As a result of the analysis of the process of functioning of a multichannel RM receiver with time division multiplexing in this work a relation was obtained for the sensitivity of an individual channel of a RM receiver with time division multiplexing.

Conclusions: It can be concluded that it is optimal to create a matrix RM receiver based on combining 16 RM channels of the superheterodyne type into one amplifier-conversion path. In this case, the total number of amplifying-converting paths is equal to four. The sensitivity of each channel remains high enough.

“Why don’t you have the sex that you want to have?” Investigating how homonormativity shapes queer men's sexual attitudes, behaviours, and representations.
Authors:   , Taylor Hunt Robbie
Published: October 2022

Queer men’s social integration into mainstream heteronormative culture has led to a rise in homonormativity. Homonormativity affords basic gay tolerance but dampens liberated queerness while maintaining systems of hetero-masculine dominance. This study aims to determine the ways that homonormativity has impacted queer men’s attitudes to sex, their sexual behaviours, and their sexual representation on screen. Specifically, it scrutinises sexual positioning roles as a key locale of insight into the social construction of sex for queer men. Sexual positioning roles determine which behaviour is adopted in anal sex: the sexually-insertive position (top), sexually-receptive position (bottom), or both (vers).

To discover the impacts of homonormativity on sexual positioning roles, semi-structured one-on-one interviews were conducted with ten queer men and non-binary people in Aotearoa New Zealand. Participants were asked about their experiences of topping and bottoming, about total tops (men who exclusively perform the sexually-insertive position during anal sex), and about their reactions to three queer male sex scenes from television and cinema. Exploratory data analysis unearthed key themes associated with facets of homonormativity.

The results show how hetero-masculine hegemony is maintained by queer men’s conceptualisation of sexual positioning roles. The queer men in this study seek and have sex within homonormative terms, where assimilation to expected masculinities prevails above actual desire when determining topping or bottoming behaviours. Furthermore, sex between men on screen is constructed in adherence to homonormativity’s preference for mainstream heterosexual acceptance over diverse queerness. The future of queer male sex must be interrogated within the growing influences of a homonormative landscape.

Periodontal diseases are the most common condition in companion animal practice. The administration of antibiotics is associated with the therapy of these diseases. The aim of the present study was to verify the effect of antibiotics on canine dental biofilm bacteria due to increasing antibiotic resistance. Dental biofilm samples were taken from six dogs before and after administration of antibiotics, specifically, the combination of spiramycin and metronidazole. The samples were cultured on solid media under aerobic and anaerobic conditions. Sequencing analysis of the 16S rRNA gene was used to identify bacterial isolates. In addition, total bacterial DNA was extracted from samples from one dog and the V3−V4 region of the 16S rRNA gene was sequenced using the Illumina MiSeq platform. Using cultivation, 55 isolates belonging to 4 phyla were isolated before antibiotics administration, and 36 isolates belonging to 3 phyla were isolated after antibiotics administration. A significant decrease was noted in the genera Porphyromonas, Neisseria and Frederiksenia, whereas there was a significant increase in the genus Streptococcus. Of the total microbiota, there were 69 operational taxonomic units (OTUs) belonging to 11 phyla before antibiotics administration, and 51 OTUs belonging to 8 phyla after antibiotics administration. A significant decrease was recorded in the genus Porphyromonas, while a significant increase in the genus Capnocytophaga. The significant effect of spiramycin and metronidazole on the genus Porphyromonas at the time of their administration was confirmed by both cultivation and amplicon sequencing.

Published: October 2022

The aim of the study was to assess the impact of social isolation of rats in the post-weaning period using behavioural tests aimed at assessing cognitive function, anxiety, and depressive-like behaviours. The monitoring was performed in male Wistar rats which were housed after weaning either individually (n = 8) or in pairs (n = 8) for 33 days. In the open field, rats kept in isolation reared less often (P < 0.05) than pair-housed rats. In the elevated plus-maze test, pair-housed rats entered the open arm more frequently (P = 0.002) and stayed in the closed arm less often (P = 0.019) compared to rats housed in isolation. In the forced swim test, climbing was seen more frequently (P = 0.016) in pair-housed rats whereas immobility was more common (P = 0.006) in rats housed individually. In the novel object recognition test, the pair-housed rats preferred (P = 0.014) the novel object whereas there was no difference (P = 0.107) in time spent by exploring familiar and novel objects in rats housed in isolation. Furthermore, juvenile rats housed for 33 days in isolation showed higher (P = 0.003) body weight gain during the monitored period than rats housed for the same period in pairs. Our findings are important not only in terms of assessing the impact of rat housing on their mental and physical development but also in terms of the accurate interpretation of the results of other experiments where the rat is used as a model organism.

Published: October 2022

Background

Acute flaccid myelitis (AFM) is a polio-like condition affecting mainly children and involving the central nervous system (CNS). AFM has been associated with different non-polio-enteroviruses (EVs), in particular EV-D68 and EV-A71. Reliable incidence rates in European countries are not available.

Aim

To report AFM incidence in children in the Netherlands and its occurrence relative to EV-D68 and EV-A71 detections.

Methods

In 10 Dutch hospitals, we reviewed electronic health records of patients diagnosed with a clinical syndrome including limb weakness and/or CNS infection and who were < 18 years old when symptoms started. After excluding those with a clear alternative diagnosis to AFM, those without weakness, and removing duplicate records, only patients diagnosed in January 2014–December 2019 were retained and further classified according to current diagnostic criteria. Incidence rates were based on definite and probable AFM cases. Cases’ occurrences during the study period were co-examined with laboratory-surveillance detections of EV-D68 and EV-A71.

Results

Among 143 patients included, eight were classified as definite and three as probable AFM. AFM mean incidence rate was 0.06/100,000 children/year (95% CI: −0.03 to 0.14). All patient samples were negative for EV-A71. Of respiratory samples in seven patients, five were EV-D68 positive. AFM cases clustered in periods with increased EV-D68 and EV-A71 detections.

Conclusions

AFM is rare in children in the Netherlands. The temporal coincidence of EV-D68 circulation and AFM and the detection of this virus in several cases’ samples support its association with AFM. Increased AFM awareness among clinicians, adequate diagnostics and case registration matter to monitor the incidence.

Published: October 2022

In response to the water shortage in Wanzhou North Station (WNS), the authors investigated the stormwater quality characteristics with different underlying surfaces of WNS and carried out stormwater reuse analysis in conjunction with the InfoWorks ICM model. The results show that during heavy, torrential, and moderate rainfall, the road stormwater runoff has the highest concentrations of pollutants, with an average EMC (event mean concentration) value of 206 mg/L for COD. For the square runoff, the average EMC values of COD, SS, TN, and TP are 108 mg/L, 395 mg/L, 2.113 mg/L, and 0.128 mg/L, in comparison, the average EMC values of the corresponding indexes for the roof runoff are 65 mg/L, 212 mg/L, 1.449 mg/L, and 0.086 mg/L, respectively, demonstrating their potential for reuse. The R2 (coefficient of determination) of SS and COD in both roof and square runoff is greater than 0.85, with a good correlation, indicating that SS removal is the key to stormwater purification. InfoWorks ICM analysis shows that the recyclable volume of rainwater from WNS in 2018 is 29,410 m3, accounting for 61.8% of the total annual rainfall. This study is expected to provide an ideal reference for the stormwater management of public buildings in mountainous areas.

Design and Responsible Innovation. Ethics and Caring as Keys to Addressing Contemporary Crises
Authors: Succini Laura , Ciravegna Erik
Published: October 2022

Current global crises have generated profound environmental, social and economic instability, exacerbating the so-called “North–South divide”. To cope with increasing uncertainty and complexity, design has faced profound structural changes and reviewed its approaches. Design has come to the Responsible Innovation concept to define perspectives on how to develop products and services with a positive impact and create new forms of individual and collective knowledge. Based on ethical values of caring, Responsible Design focuses on ideas and practices that enable designers to address complex eco-socio-political wicked problems. At the intersection between Responsible Innovation and design cultures and practices, several examples of local and global initiatives can be identified. To better understand the state of the art and envision possible developments of Responsible Design, a selection of case studies was analysed, and action research was carried out. Thus, two perspectives emerge: 1) Design for Responsible Innovation; 2) and Responsible Innovation applied to Design. In both views, design becomes ethically responsible, empowering people to take care of themselves, their communities and the environment.
Domestication, Design and Technological Objects: Affordance and the Challenge of the Virtual
Authors: Proverbio Paola , Chiesa Rosa
Published: October 2022

In its relationship with technological objects, design has historically used aesthetic, stylistic and symbolic devices to tame what was perceived as wild. Drawing on the ideas offered by the framework of domestication, this paper addresses the issue of the relevance of the relationship between user and technological object in an era characterised by the rapid transformation of physical objects towards dematerialisation. Does it still make sense to speak of affordance in the face of a shift from the physical plane to the virtual in the user-object relationship? And what happens to this relationship when technology loses its materiality and becomes ephemeral?

Age Determination of Ophisops elegans (Ménétriés, 1832) (Squamata: Lacertidae) Populations from Different Altitudes in Turkey
Authors: Güler Habibe , Üzüm N.
Published: October 2022

In this study, comparison of body size and age of two populations of Ophisops elegans from different altitudes was carried out (Kepez, 180 m; Paşayaylası, 1250 m). We applied phalangeal skeletochronology to obtain the age of juveniles and adults by counting the lines of arrested growth (LAGs) in phalangeal cross-sections. Male-biased sexual dimorphism was observed in Kepez, while female-biased sexual dimorphism was determined in the Paşayaylası population. Both male and female individuals in Kepez and Paşayaylası populations reached sexual maturity at the age of 3. The maximum age or longevity was calculated as 7 years in males and 9 years in females. Considering all individuals, the Kepez population was found to be older than Paşayaylası population. For both populations, a significant positive correlation was found between age and size in males and females.

The objective of this study is to determine hospitalization and case-fatality rates in adult patients diagnosed with COVID-19 at a large academic medical center in the United States of America which predominately serves rural and underrepresented populations. EMR data abstraction of a cohort of lab-confirmed COVID-19, outpatient and inpatient, adult patients, who tested positive at Augusta University Medical Center (AUMC) in 2020 (N = 18,403) was conducted. Eligible patients were identified using the data mining tool, i2b2. COVID-19 hospitalization and case fatality rates were calculated. Logistic and Poisson regression models were constructed to identify characteristics associated with hospitalization, death, and hospital stay. The hospitalization rate was 3.97%. Patients aged 45-64 and 65+ had significantly higher hospitalization rates. Compared to White, hospitalization rates were higher in Black (AOR 2.35, 95% CI, 1.99-2.77, p 0.001) and Hispanic patients (AOR 1.92, 95% CI, 1.92-3.01, p 0.01). Overall COVID-19 case fatality rate was 0.62% and, in hospitalized patients, was 14.25%. Patients 65+ had higher odds of death (AOR 7.57, 95% CI, 3.25-22.13, p 0.001). Case fatality rates did not vary by race. In conclusion, in a primarily rural and underserved population prior to known effective therapy, overall and hospitalized case fatality rates were similar to studies from large urban areas. Keywords: COVID-19, case fatality, hospitalization rate, rural health.
The coloniality of girls’ education in Sri Lanka. Agency, transformation and adaptation
Authors: Albrecht Jessica A
Published: October 2022

This article looks at the global, entangled history of girls’ education in late colonial Sri Lanka. This article looks at two European women educators, Lilian Nixon and Florence Farr, who came to the island to become principals of girl’s schools at the beginning of the twentieth century. Both had been educated at the Cheltenham Ladies College, England, whose impact on the education of girls, in England and the Empire, is crucial. By looking at the discussions on girls’s education at CLC, Ladies’ College (Nixon), Colombo, and Ramanathan College (Farr), Jaffna, Sri Lanka, this article proposes a new, global historical, approach to the history of girls’ education and female empowerment, colonial power structures and postcolonial transformations. I will argue that the answer to the question whether colonial girls’ education and its successors is seen as empowering, depends on the conceptualisation of empowerment and agency in their relation to religion. The case study of Sri Lanka can, thereby, serve as an example to instigate new discussions within postcolonial and feminist approaches in history.
Decentering the Enlightenment: Crossing Global and Gender Perspectives2
Authors: Bolufer Mónica , Serrano Elena
Published: October 2022

Global and transnational history and women’s and gender history are dynamic historiographical currents that invite more intense cross-fertilization—especially in studies on the Enlightenment and its open legacy. Our article seeks to stimulate theoretical and methodological discussion on how these approaches might fruitfully interact. What can a gender perspective add to current perspectives on a global Enlightenment? And vice-versa, what do transnational and global perspectives that are interested in cultural transfers and sensitive to empire, race, and ethnicity add to current studies on gender and the Enlightenment? Building on the experience and ongoing research of our collective project CIRGEN: Circulating Gender in the Global Enlightenment: Ideas, Networks, Agencies, we aim to further efforts to decenter the Enlightenment in its multiple senses in relation to geographies, actors, and gazes.
Más allá de la lengua. Una aproximación al análisis iconográfico de Malintzin como guerrera en los lienzos de la conquista: El lienzo de Tlaxcala y el Manuscrito de Glasgow
Authors: Sola Rubio Nathaniel
Published: October 2022

Hernán Cortés dio una concisa y breve definición de Malintzin (Malinche, Malinalli, o Doña Marina) al describirla como “la lengua”, de quienes otros cronistas, más tarde, se hicieron eco, pasando a la historiografía como una participe activa de la conquista de México. Sin embargo, diversos investigadores e investigadoras se han esforzado por deconstruir el relato hegemónico que ensalza, ignora o desprecia a la intérprete. Dentro del conjunto de estos análisis se integra el presente artículo, teniendo como objetivo, aproximarse desde los métodos de la Historia del Arte a la representación de Malintzin como guerrera en el Lienzo de Tlaxcala y Manuscrito de Glasgow. Ambos documentos (de procedencia tlaxcalteca) expondrán a Malintzin en el centro de la narración pictográfica, adjudicándole un papel que irá más allá de su simple intervención como “lengua” del conquistador. Se expondrán las relaciones iconográficas y contextuales que acogen la imagen de Malintzin como guerrera en torno a la tradición cultural proveniente del universo indígena y el europeo, con el fin de observar las influencias que han marcado el imaginario de Malintzin a partir de una figura vinculada a la legitimidad y lo místico.

Rumex acetosella L. (sorrel) is a plant belonging to the Polygonaceous family and is a species that grows naturally across Turkey. In this study, the characterization of silver nanoparticles (AgNPs) obtained from the Rumex acetocella L. (RA) plant using the green synthesis method was performed and their antimicrobial activities were investigated. AgNPs were successfully synthesized in the first stage of the study using plant extract taken from plant samples collected from the natural growing environment. Characterization of synthesized AgNPs was performed using appropriate analytical methods (UV-vis, FT-IR, XRD, SEM-EDX, TEM, Zeta Potential and Zeta Sizer). According to the analysis results, it was determined that AgNPs had a maximum absorbance at 476 nm wavelength, a pentagonal, hexagonal, and spherical appearance, a size of 29.16 nm, and a zeta potential of -9.88 mV. The antimicrobial activities of AgNPs were tested using the microdilution technique, in which Minimum Inhibition Concentration (MIC) values were determined on gram-positive Staphylococcus aureus, Bacillus subtilis and gram-negative Pseudomonas aeruginosa, Escherichia coli bacteria and Candida albicans fungus. It showed a very strong antimicrobial effect on C. albicans, S. aureus and P. aeruginosa. Consequently, AgNPs had stronger antimicrobial activity at low concentrations and when compared to commercial antibiotics.
