Published: June 2023

To date, an important role in many areas of economic activity is played by road freight transport. First of all, it depends on how quickly and reliably the goods will be delivered from one place to another. With an extensive list of various goods that need to be transported, there is no less a large selection of vehicles to perform these tasks.

Due to the fact that heavy trucks are currently prohibited from entering most cities, low-tonnage trucks, including vans and trucks of the transport category “N1”, have become in demand. Their main purpose is the transportation of small shipments within the city or over relatively short distances.

Low-tonnage trucks should have not only high dynamic characteristics, but also low fuel consumption. Numerous studies have shown that the most promising direction of increasing dynamic characteristics and reducing fuel consumption are mechanical energy recovery devices that accumulate the energy of the rotating masses of the car during braking and transfer it to the same rotating masses at the moment the car starts moving. Analysis of the movement of light trucks using a mechanical energy recovery device can reveal changes in the dynamics of light trucks and fuel consumption.

Purpose. Investigation of changes in dynamic characteristics and fuel consumption of a low-tonnage truck with a mechanical energy recovery unit using a model in the MATLAB Simulink environment.

Methodology. Methods of mathematical modeling and analysis were used in the article.

Results. The parameters showing the efficiency of operation of a low-tonnage truck with a mechanical energy recovery unit are obtained.

Practical implications. The results obtained can be applied when designing a car to identify the optimal parameters of the vehicle’s power plant, which are used together with mechanical energy recovery devices.
‘My maine hope is, to begin the sport at Millaine’: Italy in Philip Massinger’s The Duke of Milan
Authors: Paravano Cristina
Published: June 2023

Philip Massinger’s The Duke of Milan (1621) clearly sits in the tradition of the Elizabethan and Jacobean Italianate tragedy and is resonant of stories, ideas, theories, and characters from Italian history and its literary tradition. This essay discusses the play as one of the earliest examples of Massinger’s interest in Italy and its culture. It investigates the play’s Italian setting and examines the influence of the Italian cultural and political legacy to offer new insights into the development of Anglo-Italian relations and England’s home and religious politics in the early 1620s.

In this paper, uncertainty is included in the extended framework of global air traffic both through the action of the wind and through the incomplete determination of the aerodynamic coefficients and the inevitable imprecision involved in the execution of ATC instructions. In order to
study the air conflict detection process in detail, the possibility of potential conflicts must be evaluated, considering the current state of the international airspace, and taking into account the uncertainty in
calculating the future position of the aircraft. A mathematical model for predicting potential aerial conflicts is necessary for this objective. In a probabilistic framework, the mathematical model thus created could be either an empirical distribution of future aircraft positions in space or a dynamic model, such as a stochastic differential equation, that describes the movement of the aircraft and implicitly defines a distribution for the position’s future of the aircraft/ future aircraft positions. Based
on the prediction model, aircraft flight safety matrices can be evaluated. The mathematical methods applied in the Detection and Resolution of Air Traffic Conflicts - CDR involve a wide range of fields, but also the appropriate modeling of physical systems such as airplanes, the codification of mathematical algorithms for conflict detection, as well as the properly applied procedures for resolving potential air conflicts.

Published: June 2023

Satellites are intended to be of massive cost, hard, or hard to keep up and fix in circle. The point of this task is to decide an effective strategy to decide the orbital and heading data for the Nano satellite. To design the exact trajectory and circle for a satellite, information regarding the components which are liable for the deviation in the method of satellites. The factors that should be taken into account to determine the exact location of the satellite. It could be accomplished with the assistance of
software responsible for orbit simulation, to do programming with Orbitron so as to get the required output. Orbitron is a simple 2D solver in which TLE files are uploaded, for AAUSAT CUBESAT. The various impacts on the satellite in space are slight deviation in the satellite from its orbit. The motion of the body with includes the disturbing forces in the orbit. However, a satellite has deviated from its normal path due to several forces. This deviation is termed as orbital perturbation. The changes in the orbital element with respect to secular variations are considered using orbital quaternions. The output from satellite dynamic model is received from attitude sensor. The comparative data (Input and
Feedback) will generate error signal. To minimize the error signal using proportional integral and derivative (PID) is proposed controller implemented with MATLAB environment.

Published: June 2023

In the proposed work, a highly sensitive reduced graphene oxide (rGO) coated etched fiber Bragg grating (eFBG) pH sensor is developed and characterized. To create the sensing probe, a nanocomposite layer of rGO is coated over the unclad area of the eFBG. The analysis of rGO material has been done using different characterization tools such as UV-VIS-NIR spectroscopy, x-ray diffraction (XRD), and field emission scanning electron microscopy (FESEM). Experiments are performed using pH samples ranging from pH 2 to pH 12 to validate the operational sensing range of the proposed sensor. The effectiveness of the proposed sensor is evaluated with various pH values by monitoring the shift in the resonance peak of the sensor’s reflection spectrum in a real-time interrogation system. The sensor performs well in both low and high pH ranges, with a maximum sensitivity of 0.232 nm/pH at pH 12. Due to a shift in the rGO’s optical band-gap at both low and high pH values in the samples, the sensor can detect minimal changes in concentration. In the reflected spectrum, the Bragg wavelength (λ
B
) shifts as a result of the change in the refractive index. The λ
B
is observed to change as the pH of the aqueous solution is changed experimentally. Its performance is shown to be minimally affected by the ambient temperature (in the range of 19−21∘C). The sensor also has the capacity for remote sensing, a quick response time, a small size, a low cost, a miniaturized probe, and the ability to reuse the probe.
Photonic reservoir computing enabled by stimulated Brillouin scattering
Authors: Phang Sendy
Published: June 2023

Artificial intelligence (AI) drives the creation of future technologies that disrupt the way humans live and work, creating new solutions that change the way we approach tasks and activities, but it requires a lot of data processing, large amounts of data transfer, and computing speed. It has led to a growing interest of research in developing a new type of computing platform which is inspired by the architecture of the brain specifically those that exploit the benefits offered by photonic technologies, fast, low-power, and larger bandwidth. Here, a new computing platform based on the photonic reservoir computing architecture exploiting the non-linear wave-optical dynamics of the stimulated Brillouin scattering is reported. The kernel of the new photonic reservoir computing system is constructed of an entirely passive optical system. Moreover, it is readily suited for use in conjunction with high performance optical multiplexing techniques to enable real-time artificial intelligence. Here, a methodology to optimise the operational condition of the new photonic reservoir computing is described which is found to be strongly dependent on the dynamics of the stimulated Brillouin scattering system. The new architecture described here offers a new way of realising AI-hardware which highlight the application of photonics for AI.
Generation of Bloch surface beams with arbitrarily designed phases
Authors: Xiang Yifeng , Lu Qijing , Wang Ruxue
Published: June 2023

We proposed a new manipulation method for Bloch surface waves that can almost arbitrarily modulate the lateral phase through in-plane wave-vector matching. The Bloch surface beam is generated by a laser beam from a glass substrate incident on a carefully designed nanoarray structure, which can provide the missing momentum between the two beams and set the required initial phase of the Bloch surface beam. An internal mode was used as a channel between the incident and surface beams to improve the excitation efficiency. Using this method, we successfully realized and demonstrated the properties of various Bloch surface beams, including subwavelength-focused, self-accelerating Airy, and diffraction-free collimated beams. This manipulation method, along with the generated Bloch surface beams, will facilitate the development of two-dimensional optical systems and benefit potential applications of lab-on-chip photonic integrations.

Tight focusing with very small f-numbers is necessary to achieve highest at-focus irradiances. However, tight focusing also means short Rayleigh length, which imposes strong demands on the precise positioning of the target at the best focus to achieve the highest on-target irradiance. We describe several near-infrared, visible, ultraviolet, soft and hard X-ray diagnostics employed in the ~10^22 W/cm2 laser-plasma experiment at the J-KAREN-P laser facility in KPSI, Japan. The experiment requires a tight focusing of ~10 J femtosecond infrared laser pulses into ~1.3-µm-diameter focal spots on stainless steel (SUS) solid targets of different thicknesses (5–20 µm). We discuss the applicability of these diagnostics to determine the best in-focus position of the target with <10 µm accuracy (i. e., within the short Rayleigh length) in high-power laser-matter experiments, and suggest which diagnostics should and which ones should not be used for this purpose. It was demonstrated that the target could be positioned to within few µm out of the best laser focus, ensuring over 80% of the ideal peak intensity.

Published: June 2023

Factors for initiating hibernation are unknown, but the condition shares some metabolic similarities with consciousness/sleep, which has been associated with n-3 fatty acids in humans. We investigated plasma phospholipid fatty acid profiles during hibernation and summer in free-ranging brown bears (Ursus arctos) and in captive garden dormice (Eliomys quercinus) contrasting in their hibernation patterns. The dormice received three different dietary fatty acid concentrations of linoleic acid (LA) (19%, 36% and 53%), with correspondingly decreased alpha-linolenic acid (ALA) (32%, 17% and 1.4%). Saturated and monounsaturated fatty acids showed small differences between summer and hibernation in both species. The dormice diet influenced n-6 fatty acids and eicosapentaenoic acid (EPA) concentrations in plasma phospholipids. Consistent differences between summer and hibernation in bears and dormice were decreased ALA and EPA and marked increase of n-3 docosapentaenoic acid and a minor increase of docosahexaenoic acid in parallel with several hundred percent increase of the activity index of elongase ELOVL2 transforming C20-22 fatty acids. The highest LA supply was unexpectantly associated with the highest transformation of the n-3 fatty acids. Similar fatty acid patterns in two contrasting hibernating species indicates a link to the hibernation phenotype and requires further studies in relation to consciousness and metabolism.
Educational innovation as a communication strategy in palliative care: A study protocol and preliminary results
Authors: Salas Moreira Ana Paula , Baceiredo Beatriz Gómez , Centeno Carlos , Reigada Carla
Published: June 2023

Introduction

Society associates palliative care with "death" or "end of life", which cause them fear and anxiety. In Spain, the media worsens the misunderstanding by depicting a wrong picture of palliative care. Educational innovation for university students may serve as an alternative communication strategy. Care and Society is a university course designed by and for students from non-health degrees to help disseminate the palliative care message. The first year of the Teach-Inn Pal project aims to evaluate the effects of the course and to identify areas of improvement.

Objective

To present an evaluation to determine if the course can work as a campaign to refocus the public opinion on palliative care and share the preliminary results of the pilot study.

Methodology

A prospective Participatory Action Research study. University students enrolled in the course (n = 29) are invited to test and redesign the palliative care message. Knowledge and empathy will be measured throughout the learning process. Afterwards, qualitative, thematic, inductive analysis of the course material will be carried out. This study is registered on the ISRCTN Registry under the name “Can a university course help communicate palliative care?” (Registration number: ISRCTN10236642).

Discussion

This study is part of a doctoral thesis. Education is used as a creative outlet, allowing rapid testing of multiple tools to create ambassadors of palliative care that may reframe the public opinion.

Conclusion

The understanding of students about palliative care changed, the overall impression of the experience was positive, and students were also able to explain palliative care to people with little or no experience in the topic. However, to determine if they became ambassadors the results of the mid-term assessment are required.

Published: June 2023

The coronavirus disease 2019 (COVID-19) pandemic has had a major influence on working patterns worldwide, given the various lockdown periods and the shift to remote working. As people’s noise perception is known to be closely linked with their work performance and job satisfaction, investigating the noise perception in indoor spaces, especially in situations where people work from home, is crucial; however, studies on this aspect are limited. Thus, here, this study aimed to investigate the relationship between indoor noise perception and remote work during the pandemic. The study assessed how people who worked from home perceived indoor noise, and how it related with their work performance and job satisfaction. A social survey was conducted with respondents who worked from home during the pandemic in South Korea. A total of 1,093 valid responses were used for data analysis. Structural equation modeling was used as a multivariate data analysis method to simultaneously estimate multiple and interrelated relationships. The results showed that indoor noise disturbance significantly affected annoyance and work performance. Annoyance with indoor noise affected job satisfaction. Job satisfaction was found to have a significant impact on work performance, particularly on two dimensions of the work performance that are crucial for achieving organizations’ goals. Moreover, one dimension of the work performance had a significant impact on annoyance. The study proposed that reducing negative perception of indoor noise and improvement of job satisfaction can lead to the maximization of one’s work performance when working from home.
Evaluation of exotic soybean accessions and their use in developing improved soybean lines with resistance to Phomopsis seed decay
Authors: Li Shuxian , Smith James R. , Zhang Lingxiao
Published: June 2023

Poor seed quality of soybean is often associated with Phomopsis seed decay (PSD), which is one of the most economically important seed diseases. Diaporthe longicolla (syn. Phomopsis longicolla) is the primary cause of PSD. Control of PSD is best accomplished by planting PSD-resistant cultivars. Sixteen exotic soybean accessions from the USDA soybean germplasm collection were screened for reaction to PSD at Stoneville, Mississippi. They consisted of maturity groups (MG) II, III and IV. Seeds from inoculated and non-inoculated plots harvested either promptly at maturity, or after a two-week delay in harvest, were assessed for infection by D. longicolla. Seed infection ranged from 0 to 36.7%. Overall, PI 417050 (MG II), PI 417017 (MG III), and PI 594692 (MG IV) had significantly (P ≤ 0.05) lower percentages of seed infected by D. longicolla and higher seed germinations than other genotypes in the same maturity groups. PI 587982A also performed well. As a result of these findings, these resistant accessions were used over multiple cycles of breeding to develop improved breeding lines with resistance to PSD and low seed damage. Breeding line 11043-225-72, with combined resistance from both PIs 417050 and 587982A, had low scores for PSD (6.7%) and seed damage (3.4%), while DS65-1, deriving resistance from PI 587982A, had the lowest seed damage score (1.1%) and the highest seed germination (85.6%) among all lines tested in 2017. DS65-1 and 11043-225-72, along with five other improved breeding lines, were provided to public soybean breeders for developing improved cultivars and germplasm lines. DS31-243 (PI 700941), derived from PI 587982A, was publicly released by the USDA in 2022. This research will lead to future releases of improved germplasm lines and cultivars with PSD resistance and high seed quality. It will also aid in disease management and be a benefit to soybean producers and the industry at large.
Abalone adhesion: The role of various adhesion forces and their proportion to total adhesion force
Authors: Xi Peng , Ye Shaobo , Cong Qian
Published: June 2023

Adhesion is the basic ability of many kinds of animals in nature, which ensures the survival and reproduction of animal populations. The aquatic abalone has a strong adhesion capacity. In this study, we observed the microscopic morphology of abalone abdominal foot surface, and found that the surface was covered with a large number of fibers. Then five types of force measuring plates were designed and processed for the adhesion test of abalone abdominal foot. According to the test results, the composition of abalone abdominal foot adhesion force was analyzed and the proportion of various adhesion force to the total adhesion force of abalone abdominal foot was calculated. Among them, the vacuum adhesion force accounts for more than half of the total adhesion force of abalone abdominal foot, and its proportion is more than 60%. Van der Waals force also plays an important role, and its proportion is more than 20%. The proportion of capillary force is very small, which is only about 1%. Its main role is to form a liquid film to prevent the gas from flowing into the sucker. The vacuum adhesion of abalone abdominal foot can be further divided into the whole adhesion of abdominal foot, the local adhesion of abdominal foot and the frictional equivalent vacuum adhesion. And the whole adhesion of abdominal foot is basically equivalent to the local adhesion of abdominal foot. This study quantifies the proportion of various adhesion forces to the total adhesion force of the abdominal foot, which provides a reference for the further study of other adhesive creatures and the design of bionic underwater adhesion devices.
Self-emulsifying drug delivery systems: A versatile approach to enhance the oral delivery of BCS class III drug via hydrophobic ion pairing

Published: June 2023

Biopharmaceutical classification systems (BCS) class III drugs belongs to a group of drugs with high solubility in gastrointestinal (GI) fluids and low membrane permeability result in significantly low bioavailability. Self-emulsifying drug delivery systems (SEDDS) considered a suitable candidate to enhance the bioavailability of poorly soluble drugs by improving their membrane permeability, however, incorporating hydrophilic drugs in to these carriers remained a great challenge. The aim of this study was to develop hydrophobic ion pairs (HIPs) of a model BCS class-III drug tobramycin (TOB) in order to incorporate into SEDDS and improve its bioavailability. HIPs of TOB were formulated using anionic surfactants sodium docusate (DOC) and sodium dodecanoate (DOD). The efficiency of HIPs was estimated by measuring the concentration of formed complexes in water, zeta potential determination and log P value evaluation. Solubility studies of HIPs of TOB with DOC were accomplished to screen the suitable excipients for SEDDS development. Consequently, HIPs of TOB with DOC were loaded into SEDDS and assessed the log DSEDDS/release medium and dissociation of these complexes at different intestinal pH over time. Moreover, cytotoxic potential of HIPs of TOB and HIPs loaded SEDDS formulations was evaluated. HIPs of TOB with DOC exhibited the maximum precipitation efficiency at a stoichiometric ratio of 1:5. Log P of HIPs of TOB improved up to 1500-fold compared to free TOB. Zeta potential of TOB was shifted from positive to negative during hydrophobic ion pairing (HIP). HIPs of TOB with DOC was loaded at a concentration of 1% (w/v) into SEDDS formulations. Log DSEDDS/release medium of loaded complexes in to oily droplets was above 2 and dissociated up to 20% at various pH within 4 h. Finding of this study suggested that improvement of the lipophilic character of BCS class-III drugs followed by incorporation into oily droplets can be deliberated as a promising tool to enhance the permeation across biological membranes.

Published: June 2023

Background

Maternal near-miss refers to women who survive death from life-threatening obstetric complications and has various social, financial, physical, and psychological impacts on families.

Objective

To explore male partners’ perceptions of maternal near-miss experienced by their female partners and the associated psychosocial impacts on their families in Rwanda.

Methods

This was a qualitative study involving 27 semi-structured in-depth interviews with male partners whose spouses experienced a maternal near-miss event. Data were analyzed using a thematic coding to generate themes from participants’ responses.

Results

Six key themes that emerged were: male partner’s support during wife’s pregnancy and during maternal near-miss hospitalization, getting the initial information about the spouse’s near-miss event, psychosocial impacts of spouse’s near-miss, socio-economic impact of spouse’s near-miss, post- maternal near-miss family dynamics, and perceived strategies to minimize the impacts of near-miss. Male partners reported emotional, social, and economic impacts as a result of their traumatic experiences.

Conclusions

The impact of maternal near-miss among families in Rwanda remains an area that needs healthcare attention. The residual emotional, financial, and social consequences not only affect females, but also their male partners and their relatives. Male partners should be involved and be well-informed about their partners’ conditions and the expected long-term effects of near-miss. Also, medical and psychological follow-up for both spouses is necessary for the enhancement of the health and well-being of affected households.
Genome-wide identification of DCL, AGO and RDR gene families and their associated functional regulatory element analyses in sunflower (Helianthus annuus)

Published: June 2023

RNA interference (RNAi) regulates a variety of eukaryotic gene expressions that are engaged in response to stress, growth, and the conservation of genomic stability during developmental phases. It is also intimately connected to the post-transcriptional gene silencing (PTGS) process and chromatin modification levels. The entire process of RNA interference (RNAi) pathway gene families mediates RNA silencing. The main factors of RNA silencing are the Dicer-Like (DCL), Argonaute (AGO), and RNA-dependent RNA polymerase (RDR) gene families. To the best of our knowledge, genome-wide identification of RNAi gene families like DCL, AGO, and RDR in sunflower (Helianthus annuus) has not yet been studied despite being discovered in some species. So, the goal of this study is to find the RNAi gene families like DCL, AGO, and RDR in sunflower based on bioinformatics approaches. Therefore, we accomplished an inclusivein silicoinvestigation for genome-wide identification of RNAi pathway gene families DCL, AGO, and RDR through bioinformatics approaches such as (sequence homogeneity, phylogenetic relationship, gene structure, chromosomal localization, PPIs, GO, sub-cellular localization). In this study, we have identified five DCL (HaDCLs), fifteen AGO (HaAGOs), and ten RDR (HaRDRs) in the sunflower genome database corresponding to the RNAi genes of model plantArabidopsis thalianabased on genome-wide analysis and a phylogenetic method. The analysis of the gene structure that contains exon-intron numbers, conserved domain, and motif composition analyses for all HaDCL, HaAGO, and HaRDR gene families indicated almost homogeneity among the same gene family. The protein-protein interaction (PPI) network analysis illustrated that there exists interconnection among identified three gene families. The analysis of the Gene Ontology (GO) enrichment showed that the detected genes directly contribute to the RNA gene-silencing and were involved in crucial pathways. It was observed that thecis-acting regulatory components connected to the identified genes were shown to be responsive to hormone, light, stress, and other functions. That was found in HaDCL, HaAGO, and HaRDR genes associated with the development and growth of plants. Finally, we are able to provide some essential information about the components of sunflower RNA silencing through our genome-wide comparison and integrated bioinformatics analysis, which open the door for further research into the functional mechanisms of the identified genes and their regulatory elements.

Our aim was to evaluate the use and application of different nonlinear mixed models, as well as to compare them with approach in nonlinear fixed models, for describing the growth curve of meat-type quails according to gender. A total of 15,002 and 15,408 records of males and females were used, respectively. The body weights were regressed on age of the animals using nonlinear models (Brody; Gompertz; Logistic, Morgan-Mercer-Flodin, Richards and Von Bertalanffy). All model parameters were considered fixed, whereas parameters related to asymptotic weight and maturity rate were fitted as random effects. The Bayesian Information Criterion was used to find the model of best fit. For both genders, the model that used the Morgan-Mercer-Flodin function with the inclusion of asymptotic weight as a random effect was considered the best-fitting model because it reduced the residual variance and increased the accuracy. Based on the lower absolute growth rate and growth velocity of male quails compared to that of females, it can be inferred that males should be slaughtered later. Given the results of this study, it can contribute to the current knowledge about animal yield, specifically at the best moment to slaughter and, this sense, improv the quality genetic of the populations in time.
Deplorable by proxy: Sartorial semiosis and the rendering of an underclass
Authors: Porter Matthew
Published: June 2023

In 2016, Donald Trump’s slogan ‘Make America Great Again’ (MAGA) – often displayed on a red cap – prompted myriad interpretations and reactions regarding the message itself and the hat it was displayed upon. Despite the hat’s polysemy, there has been no shortage of institutional attempts to codify the hat and, by extension, the wearers of the hat as racist or otherwise ‘deplorable’ (). By tracing the functional lineage of the MAGA hat alongside a case study of the 2019 Covington Catholic incident, this article uses media discourse analysis to investigate dress as a factional sociopolitical player while interrogating how cultural institutions contribute to social meaning-making, which in turn can leverage dress’s power and unduly malign constituent wearers. Employing theories of sartorial embodiment, the MAGA hat’s enthymematic reading and a critical linguistic frame, this article critiques the pathology of marginal myopia and locates how pejorative ascriptions by proxy of the MAGA hat render Trumpian conservatives, primarily of the White male ilk, as marginal subjects.
Self-perception and body image among cancer survivors
Authors: Yoo Jeong-Ju , VanHoose Lisa
Published: June 2023

The goal of this study is to identify the self-perception of cancer survivors’ body image distress and to illustrate fashion-oriented consumption as a coping mechanism. Retail therapy (RT) may be a promising intervention for cancer survivors to mitigate body image distress and promote positive health outcomes. The impact of cancer treatments on each survivor should be considered based on their body investment, cancer type, diagnosis, body weight and other demographic characteristics. Developing mitigation strategies using RT for cancer survivors with visible physical changes is crucial. Fashion-oriented shopping can give cancer survivors a sense of control and boost a positive self-image. Cancer survivors who are highly conscious of societally prescribed definitions of normal appearance may benefit significantly from RT.
The view from Warsaw: Italian neorealism in Stalinist-era Poland
Authors: Dygul Jolanta
Published: June 2023

Italian neorealist films were quite popular in Stalinist-era Poland (1945–53). As part of the propaganda strategy, they were used to create a negative image of life in western countries, thus confirming the omnipresent vision of ‘rotten capitalism’. The social criticism contained in neorealism was manipulated through a modal framework that explained to the Polish audiences all phenomena as a product of a bad social system based on injustice and exploitation. The aim of this article is to examine Polish reviews of two neorealist films: Ladri di biciclette (Bicycle Thieves) () and La terra trema (The Earth Trembles) () both presented to Polish audiences in 1951.
‘Where is here?’: Place and rurality through the cinematic child
Authors: Buesa Andrés
Published: June 2023

This article explores the ways in which Alice Rohrwacher’s Le maraviglie, as exemplary of a growing tendency within contemporary cinema, negotiates ideas of place and belonging through the trope of the rural child. It contends that the cinematic child in the film articulates a dynamic and open – rather than static, localized and fixed – understanding of place. Against the Romantic tendency to associate childhood and nature as a way of grounding essentialist ideas of place, the film draws on children’s heightened openness to the others in order to embody what Doreen Massey calls a global sense of place (1991): a sense of place built upon the social relations created in the encounter with the other. By bringing together film analysis, childhood studies and theorizations of place, this article builds an interdisciplinary approach to look into this shifting use of the child figure. It first explores two different reactions to the threats of the global presented in the film – the family’s mode of living and the reality TV show contest – as reterritorializing attempts to ground a sense of place in the local. It then argues that, in the way in which the child protagonist bonds with a newcomer to the farm, she rejects both these notions and opens herself up to alternative understandings of place. In a gradual recovery of her childhood that culminates in the last scene of the film, she comes to embody a progressive sense of place that emphasizes the hybrid nature of global places.

El papel de las universidades en lucha contra la pandemia

Las universidades brasileñas hacen frente a tres crisis interrelacionadas. La primera es el resultado de las políticas neoliberales que han llevado a recortes presupuestarios profundos en educación, ciencia y tecnología. La segunda es la de la propia pandemia, que ya se ha cobrado la vida de más de 600 mil brasileños. Las universidades trabajan para proteger la vida de su comunidad y de la sociedad en general. El sistema de universidades públicas lleva a cabo actividades de extensión en la comunidad universitaria, especialmente pruebas para la detección de infección, fabricación de equipos de protección, investigación básica y aplicada, incluyendo el desarrollo de vacunas, sin olvidar el papel esencial de los Hospitales Universitarios en el tratamiento de los pacientes. La tercera crisis es el resultado del movimiento de extrema derecha, autoritario y negacionista que tiene a las universidades públicas en su punto de mira. Sin embargo, las universidades se han visto fortalecidas por el respaldo de la población, debido al reconocimiento de su rol en la prevención y tratamiento del COVID-19. Las actividades docentes se realizan de forma remota, pero deben hacer frente al desafío que supone la dificultad de acceso a internet de una gran parte de su comunidad. La inclusión digital debe considerarse un derecho de la población universitaria y un deber del Estado tanto durante la pandemia como también en la postpandemia.
Evaluación crítica, medicina basada en evidencias y divulgación científica durante la pandemia vinculada al COVID-19 en Brasil
Authors: Campos Pellanda Lucia
Published: June 2023

El objetivo de este texto es reflexionar sobre el papel de la divulgación de la evidencia científica y la medicina basada en evidencias en el contexto de la pandemia de COVID-19 en Brasil y la necesidad de replantear la educación a la luz de estas reflexiones. Uno de los aspectos en los que hubo más discordancia en los mensajes públicos fue con relación a las medidas no farmacológicas y al tratamiento. La amplia disponibilidad de información democratiza el conocimiento, pero también genera la necesidad de alfabetización científica de la población en general y de los profesionales de la salud para una adecuada selección y evaluación crítica de la evidencia, ya que la multiplicidad de mensajes sobre formas de hacer frente a la epidemia posiblemente ha contribuido a la dificultad de control en el país.

Background and Aim: Paratuberculosis (PTB) or John’s disease is a chronic disease of ruminants impeding the reproduction and productivity of the livestock sector worldwide. Since there is a lack of pathological studies explaining the nature and development of the disease in camels, this study aimed to highlight the anatomopathological changes of PTB in camels, which may help in verifying and validating some diagnostic tests used to detect the etiology of the disease in camel tissues.

Materials and Methods: In August 2017, at Alselaa border’s Veterinary Clinic of Al Dhafra Region, Western Abu Dhabi, UAE, one imported culled she-camel of 2 years old was subjected to clinical, microscopic, and anatomopathological investigations along with real-time quantitative polymerase chain reaction (q-PCR) to confirm the infection and correlate between clinical signs and pathological lesions of the PTB in dromedary camels.

Results: Clinically, typical clinical signs compliant with the pathognomonic gross and histologic lesions of PTB were seen in naturally infected dromedary camel. As presumptive diagnosis microscopically, acid-fast coccobacillus bacterium clumps were demonstrated in direct fecal smears as well as in scraped mucosal and crushed mesenteric lymph node films, and in histopathological sections prepared from a necropsied animal and stained by Ziehl-Neelsen stain. Free and intracellular acid-fast clump phagosomes were further confirmed as Mycobacterium avium subsp. paratuberculosis by q-PCR.

Conclusion: Clinical signs and pathological lesions of paratuberculosis in a dromedary camel were found to be similar to those of the other susceptible hosts.

Keywords: acid-fast bacteria, dromedary camel, Mycobacterium, paratuberculosis.
iskolai kötődés kapcsolata a serdülők jóllétével és rizikómagatartásával
Authors: Dudok Réka , Pikó Bettina
Published: June 2023

Az iskolai kötődés biztosítja, hogy a diákok azonosulhassanak az iskolájukkal, az intézmény részének érezzék magukat, és szociális kapcsolatokat alakítsanak ki kortársaikkal és tanáraikkal. Az iskolai kötődés minősége kihat tanulmányi előmenetelükre, tanulási motivációikra, szociális készségeikre, valamint testi és lelki jóllétükre is. Tanulmányunk célja az volt, hogy elemezzük az iskolai kötődés különböző dimenziói (úgymint az iskolához, a tantárgyakhoz, az iskolai környezethez, a kortársakhoz, valamint a tanárokhoz való viszony) és a tanulók jólléte, valamint rizikómagatartása közötti összefüggéseket. A kutatásban 11–18 éves általános és középiskolás tanulók (M = 13,6 év, SD = 1,8; a fiúk aránya = 54,7%) vettek részt, az adatgyűjtés Budapesten és a környező falvakban történt. A dohányzást és alkoholfogyasztást tartalmazó kérdések, valamint az Iskolai Kötődés Kérdőív (Szabó és Virányi, 2011) mellett a következő skálák szerepeltek az elemzésben: WHO Jóllét Kérdőív, Élettel Való Elégedettség Skála, Serdülőkori Pszichológiai Jóllét Kérdőív. Eredményeink szerint a nemdohányzó és alkoholt nem fogyasztó tanulóknál magasabb az iskolai kötődés szintje, mint a szerhasználó társaiknál. Emellett az iskolai kötődés és a mentális egészség kapcsolata között pozitív irányú korreláció található, úgymint az általános jóllét, az élettel való elégedettség és a pszichológiai jóllét esetében. Az iskolai attitűdök, közöttük az iskolai kötődés megismerése kulcsfontosságú az eredményes tanuláshoz, a rizikómagatartások megelőzéséhez, valamint a tanulók jóllétének elősegítéséhez.
Welche Beiträge kann die Regionalplanung zur Umsetzung einer „nachhaltigen” Rohstoffsicherung leisten?
Authors: Mühl Gerald
Published: June 2023

The current paradigm guiding regional planning is that of sustainable spatial development. Among the challenges this poses is the task of both controlling the extraction of and securing the supply of raw materials found close to the surface. In the context of this extremely fraught task, this article discusses rules for dealing with natural assets. It is increasingly coming to be accepted that, in some form or other, natural resources have to be managed. Since the function of spatial planning consists in ordering and safeguarding types of land use, the contribution it might possibly make to resource management would appear initially to be negligible indeed. However, with regard to certain raw materials (sand and gravel) there is considerable scope for action within spatial planning.
Räumliche Praktiken der Energiewende am Beispiel der Biogaserzeugung in Rheinland-Pfalz
Authors: Faller Fabian
Published: June 2023

The energy transition has received increasing scientific interest over the last decade. A main focus is set on regional transformations from conventional to renewable energies. There, regions are typically defined as action spaces nested between local and national policy levels, and transition processes are analyzed in or between such regions. Adding on this, the main purpose of the paper in hand is to understand the processes that lead to the formation and change of such regions. How get energy regions constituted and transformed? Which geographical aspects are important for these processes? A qualitative case study from western Rhineland-Palatinate in Germany focusing on biogas co-fermentation explores different practices and routines of energy producers that illuminate the constitution, stabilization and transformation of “energy regions”. Problem-centered interviews are conducted with 20 plant operators to understand individual perceptions of routines and practices. The findings from these micro case studies are generalized and show the changing practices over time, their spatial connotations, and their importance for the energy transition. The paper discloses both, individual (practical knowledge and cognitive preconditions) and structural contexts (accessibility and availability of knowledge, existing networks and political frameworks) that are important for transition practices. Thereby, we show that over time the energy region changes from a subject oriented space to a regional network space bound to actors practicing in spatial proximity and building on mutual learning effects.
