Exploring a possible link between insulin resistance, vaccine to SARS CoV 2 and glycaemic disturbances in diabetes mellitus, type 2
Authors: ASV Prasad
Published: August 2021

The occurrence of both hyperglycaemia and hypoglycaemia, individually and in combination is reported in the literature, occurring in various insulin resistance (IR) syndromes, both to endogenous insulin, like Hirata disease, otherwise called the Insulin Autoimmune syndrome (IAS), type A, I R, Type B, IR etc. and to exogenous administered insulin, like, exogenous insulin antibody syndrome, (EIAS), non- classical auto immune syndrome to exogenous insulin, etc. Glycaemic disturbances without IR and in non-diabetics, like idiopathic and symptomatic reactive hypoglycaemias are also described in the literature. This author, recently reported for the first time, a biphasic post - vaccinal syndrome, following vaccination for Covid 19 (Covishield), causing glycemic disturbances in an elderly diabetes mellitus type 2 (DM2) patient on insulin who had moderate IR. Insulin resistance to exogenous insulin observed in the patient, is considered crucial for the occurrence of the observed clinical syndrome as, an increase or decrease of IR, and could explain the observed glycaemic disturbances. The IR to exogenous insulin, and the vaccine to Covid 19, both have immunological basis. The immunological aspects of both IR and the Covid 19 vaccine are briefly reviewed to explore any possible interaction between the two, that could explain the observed clinical syndrome, referred to above. Also, the various underlying mechanisms for the glycaemic disturbances, in the above-mentioned IR syndromes and non-IR or r syndromes are explored as to shed some light on the mechanism of the glycaemic disturbances in the syndrome reported. A hypothesis is suggested, taking into consideration, the aforesaid observations. Apart from IR to exogenous insulin, other unidentified factors that might be causing the clinical syndrome reported, and which might account for its paucity of reporting, need to be investigated by future research.

Does apple canker develop independently on leaf scars of a single apple shoot?
Authors: Xu Xiangming , Olivieri Leone , Gange Alan C. , Vorster Lizelle , Rice Don , Campbell Rebecca E. , Walter Monika
Published: August 2021

European apple canker, caused by Neonectria ditissima, causes serious damage to apple trees, particularly young trees. Canker management is difficult because of the limited availability of effective fungicides, the long latency period, inoculum abundance and host resistance in commercial cultivars as well as the need for costly manual pruning interventions.
To understand disease aggregation for more effective pruning management, we assessed whether canker infection and subsequent lesion development on leaf scars are independent from each other on the same shoot. Four inoculation experiments were conducted: one in glasshouse, and three in orchards. On each shoot, 10 consecutive leaf scars were inoculated and assessed for visible cankers over time in situ. Number of cankers developed per shoot as well as spatial distribution of these cankers within a shoot was statistically analysed.
Most data of the number of visible canker lesions on a single shoot failed to fit binomial distributions (indicator for independence) and were fitted much better by beta binomial distributions. In a number of cases (4–20%), there appeared to be positive association between lesion development on neighbouring leaf scars. However, in one experiment where laboratory incubation and isolation of N. ditissima from inoculated but asymptomatic leaf scars (after eight months’ field incubation) were used the results suggested independence of canker development on a single shoot.
 We conclude that apparent aggregation of canker lesions on individual shoots is likely to originate from host responses. Such aggregation of canker lesions on individual shoots should be taken into consideration for field disease assessment and management.

Assessing Summer Pond and Lake Inlet Use by Gray Treefrogs (Hyla versicolor/chrysoscelis complex) Using PVC Pipe Traps in Northwest Missouri
Authors: McGhee J. D.
Published: August 2021

The widespread decline in amphibian populations highlights the need for establishing rigorous monitoring methods for long-term population studies. In an attempt to launch a long-term monitoring study for a Gray Treefrog complex (Hyla versicolor LeConte /chrysoscelis Cope, hereafter treefrog) population in northwest Missouri, I tested the use of PVC pipe traps in a system of ponds and inlets along a lakeside habitat for three years. For each pond (3) and inlet (2), I established an array of 16 pipes so as to compare differences in use between pipe location, ponds and inlets, and sex ratio between sites. Pipes were checked twice a week during the summer for the presence of treefrogs. Treefrog usage of pipes between ponds and inlets were compared using a contingency table analysis, while an ANOVA was used to assess differences in sex ratios between sites (α = 0.05). A single inlet was used by treefrogs more heavily than the other ponds or inlet (G = 13.61, df = 3, P = 0.0035), however, I found no differences in terms of pipe location within a pond or inlet. Mean sex ratio between water bodies varied but did not significantly differ. There appears to be little effect in terms of pipe placement within our 50 m buffer from the water's edge, but unique habitat effects at sampling locations may significantly affect detection rates or usage.

In production and repair of mechanical engineering products, poor preparation of surfaces for gluing leads to a decrease in adhesion or even to the destruction of the adhesive bond. The level of strength of the adhesive bond is determined not only by the absence of contamination on the surfaces to be bonded, but also largely depends on the type of materials to be bonded, the properties of the adhesive used and the geometric parameters of the surface. The analysis results of the quality and roughness of aluminum and steel surfaces obtained by various methods of machining are discussed. The shear test results for adhesive joints are presented. The tests were carried out on adhesive joints of aluminum and steel substrates, the surfaces of which were treated with sanding belts with grit sizes P40, P80 and P120 before gluing. A metal-filled adhesive compound based on epoxy resin with the addition of 3% aluminum powder (by weight) was used as the glue. The character of destruction of the studied adhesive joints is described. Recommendations on method srelection for machining aluminum and steel materials before gluing are presented.
Comparative Analysis of Compact Satellite Polarizers Based on a Guide with Diaphragms
Authors: Piltyay Stepan
Published: August 2021

In this article we carry out the comparative analysis of new compact satellite polarisers based on a square guide with diaphragms. The main electromagnetic parameters of the developed microwave guide devices with various amount of diaphragms were obtained within the satellite frequency interval from 10.7 GHz to 12.75 GHz. Waveguide polarization converters with different amount of diaphragms from 3 to 5 have been designed and optimized. The main parameters of the presented polarizer were calculated applying the numerical method of finite integration in the frequency domain. Optimization of the electromagnetic parameters of the developed waveguide devices was carried out using the finite elements method in the frequency domain. As a result, sizes of the guide polarizer designs have been optimized for the provision of improved polarization and phase parameters. The performed analysis showed that a waveguide polarizer with five diaphragms has the best electromagnetic parameters. The developed compact polarizer with five diaphragms based on a square guide provides a minimum deviation of the output phase difference from 90 degrees and high level of isolation between linear polarization over the entire operating frequency range. Presented in the article compact waveguide polarization converters can be applied in modern satellite systems, which require efficient polarization transformation and separation of signals.
Information Resources Economy in Satellite Systems based on New Microwave Polarizers with Tunable Posts
Authors: Piltyay Stepan
Published: August 2021

One of the fundamental problems of modern digital telecommunications is the economy of digital information and frequency resources, which are highly limited. The introduction of novel telecommunication systems and 5G networks requires the search of principal solutions for economy and reusing of frequency spectrum. Therefore, modern wireless mobile, terrestrial and satellite systems use variety of new technologies to increase the information capacity of communication channels for the economy of limited frequency resources. One of the most effective ways to reuse the operating frequency band of the information system is to apply antennas with polarization signal processing. Such systems provide the possibility to transmit and to receive simultaneously signals with different types of polarization. Consequently, the application of electromagnetic waves with two orthogonal polarizations improves the information characteristics of wireless systems for various purposes. This allows to double the information capacity of mobile, terrestrial and satellite communication channels. In addition, polarization processing is carried out in meteorological and radar systems for receiving, transmitting and processing of information. The essential elements of such systems are microwave polarizers and orthomode transducers. The electromagnetic characteristics of these devices affect greatly the characteristics of the whole system. Main electromagnetic characteristics include phase, matching and polarization parameters. The article presents the results of development of a compact tunable polarizer based on a square waveguide with three posts. The developed polarizer operates in the X-band from 8.0 GHz to 8.5 GHz. Created mathematical model of the polarizer is based on the scattering and transmission matrices. To verify correctness of the developed theoretical model the calculation of all characteristics was also performed numerically using the finite integration technique. The developed compact polarizer based on a square waveguide with three posts allows to tune its matching and polarization characteristics by changing the heights of all posts. The main advantages of the developed polarizer are small dimensions, the tuning option and stability of characteristics of polarization transformation.
Cryoturbation leads to iron-organic carbon associations along a permafrost soil chronosequence in northern Alaska
Authors: Joss Hanna , Patzner Monique , Maisch Markus , Mueller Carsten , Kappler Andreas , Bryce Casey
Published: August 2021

In permafrost soils, substantial amounts of organic carbon (OC) are potentially protected from microbial degradation and transformation into greenhouse gases by association with reactive iron (Fe) minerals. As permafrost environments respond to climate change, increased drainage of thaw lakes in permafrost regions is predicted. Soils will subsequently develop on these drained thaw lakes, but the role of Fe-OC associations in future OC stabilization during this predicted soil development is unknown. To fill this knowledge gap, we have examined Fe-OC associations in organic, cryoturbated and mineral horizons along a 5500-year chronosequence of drained thaw lake basins in Utqiaġvik, Alaska. By applying chemical extractions, we found that ~17 % of the total OC content in cryoturbated horizons is associated with reactive Fe minerals, compared to ~10 % in organic or mineral horizons. As soil development advances, the total stocks of Fe-associated OC more than double within the first 50 years after thaw lake drainage, because of increased storage of Fe-associated OC in cryoturbated horizons (from 8 to 75 % of the total Fe-associated OC stock). Spatially-resolved nanoscale secondary ion mass spectrometry showed that OC is primarily associated with Fe(III) (oxyhydr)oxides which were identified by 57Fe Mössbauer spectroscopy as ferrihydrite. High OC:Fe mass ratios (>0.22) indicate that Fe-OC associations are formed via co-precipitation, chelation and aggregation. These results demonstrate that, given the proposed enhanced drainage of thaw lakes under climate change, OC is increasingly incorporated and stabilized by the association with reactive Fe minerals as a result of soil formation and increased cryoturbation.
A Multivariate Two-Level Analysis of Higher-Education Course Characteristics Relating to Academic Procrastination
Authors: Bäulke Lisa , Dresel Markus
Published: August 2021

Procrastination is a widespread phenomenon in higher education. Recently, aspects of the higher education context targeting self-regulation, social characteristics and task characteristics have been theoretically linked to procrastination. However, only a few and mostly univariate studies on university course characteristics and their relations to procrastination exist. Therefore, the aim of the present study was to integrate several course characteristics, examine in which way they relate to procrastination, and determine if these relations are observable above and beyond individual motivation. We conducted a multivariate two-level study with a sample of 90 courses with 1,809 students from different faculties and semesters. Based on previous conceptualizations and findings, we included twelve course characteristics that potentially affect procrastination. Results imply that academic procrastination is associated with several course characteristics to a considerable degree, especially with the degree in which the course context satisfies basic needs as well as with the clarity and difficulty of assignments.
Changes in Autistic Symptoms and Adaptive Functioning of Children Receiving Early Behavioral Intervention in a Community Setting: A Latent Growth Curve Analysis
Authors: Préfontaine Isabelle , Morizot Julien , Lanovaz Marc J , Rivard Mélina
Published: August 2021

Despite showing robust effects in well-controlled studies, the extent to which early intensive behavioral intervention produces positive changes in naturalistic, community-based settings remains uncertain. Thus, our study examined changes in autistic symptoms and adaptive functioning in 233 children in children with autism receiving early behavioral intervention in a community setting. The results revealed nonlinear changes in adaptive functioning characterized by significant improvements during the intervention period and a small linear decrease in autistic symptoms from baseline to follow-up. The intensity of intervention, age at enrolment, IQ and autistic symptoms were associated either with progress during the intervention period or maintenance during the follow-up period. Taken together, these results underline the importance of conducting further replications in community settings.
"I Don't Want Everybody to Vote": Christian Nationalism and Restricting Voter Access in the United States
Authors: Perry Samuel , Whitehead Andrew L , Grubbs Joshua B.
Published: August 2021

Though the persistence of voter suppression and disenfranchisement in the US is well-documented, we still know little about their contemporary ideological underpinnings beyond partisanship and racial resentment. Highlighting the Christian Right’s influence in driving anti-democratic sentiment in the post-Civil Rights era, we propose contemporary ideological support for restricting the vote generally, and specifically, to those who prove “worthy,” is undergirded by a pervasive ideology that cloaks authoritarian ethno-traditionalism with the ultimacy and polysemic utility of religious language―Christian nationalism. Nationally representative data collected weeks before the November 2020 elections reveal Christian nationalism is a leading predictor that Americans deny that voter suppression is a problem, believe that the US makes it “too easy to vote,” believe that voter fraud is rampant, and support measures to disenfranchise individuals who could not pass a basic civics test or who committed certain crimes. Interactions show Christian nationalism’s influence is particularly strong among men across most outcomes and, regarding voter suppression, whites compared to Blacks. We argue Christian nationalism seeks to institutionalize founding ideals in which civic participation is rooted in hierarchies, being restricted to a “worthy” few. Appeals to America’s religious heritage thus facilitate stratifying America’s citizenry and justifying restricting participation to preserve dominance.
Periventricular nodular heterotopias an atypical manifestation of Joubert syndrome
Authors: Mishra Himanshu , Kumar Amit
Published: August 2021

Joubert syndrome (JS) is characterized by varying degrees of mid and hindbrain malformations. A thickened superior cerebellar peduncle (“molar tooth sign”), varying degree of cerebellar vermian clefting, and an oddly shaped (“bat-wing”) fourth ventricle are essential diagnostic cues on imaging. When JS is associated with renal, ocular, hepatobiliary, or oro-facial abnormalities, the term Joubert syndrome and related disorders (JSRD) is used.

We report a classic case of this rare disease in a 5 month old male child who presented to our department for assessment of developmental delay. MRI revealed molar-tooth appearance of midbrain, an abnormally shaped fourth ventricle, and vermian aplasia. Additional findings present in our case were corpus callosum dysgenesis, colpocephaly, generalized cortical atrophy, and periventricular nodular heterotopia. Subsequently, an ultrasound of the abdomen was performed to look for any associated anomalies. It revealed diffuse bilateral echogenic kidneys with attenuated corticomedullary differentiation (likely due to micro cysts in medulla) and few thin-walled peripheral renal cortical cysts.

Callosal dysgenesis, colpocephaly, cortical atrophy and cortical heterotopias are less common manifestations of JS/JSRD and periventricular nodular heterotopia has been infrequently reported in cases of Joubert syndrome.

Key-words: Joubert Syndrome, MRI, Molar Tooth Sign, Periventricular Nodular Heterotopia, Bilateral Echogenic Kidneys

Published: August 2021

Artikel ini merupakan hasil kajian kepustakaan yang bertujuan untuk menganalisis strategi pembelajaran menyenanggkan dengan Joyful Learning. Banyak mata pelajaran di sekolah/madrasah berisi konsep-konsep teoritis dan untuk menguasainya membutuhkan memori otak untuk menghafalnya. Proses menghafal tersebut seringkali menimbulkan kesan bahwa mata pelajaran tersebut menjadi tidak menarik dan membosankan. Bagi peserta didik yang tidak suka menghafal, maka mata pelajaran yang demikian menjadi sulit untuk dikuasai sehingga tujuan pembelajaran yang telah ditetapkan tidak tercapai yang berimplikasi pada ketidaktuntasan dalam hasil belajar. Melihat situasi yang demikian,maka guru yang profesional perlu menggunakan strategi yang tepat agar pembelajaran yang dilaksanakan berlangsung dengan aktif, kreatif, efektif dan menyenangkan.Salah satu strategi yang perlu diterapkan oleh guru dalam pelaksanaan pembelajaran adalah joyful learning (pembelajaran menyenangkan). Menerapkan strategi pembelajaran joyful learnig pada prinsipnya sesuai dengan anjuran pemerintah bahwa guru yang profesional berkewajiban untuk menciptakan suasana pembelajaran yang bermakna, menyenangkan, kreatif, dinamis dan dialogis. Hal yang lebih penting lagi bahwa  proses pembelajaran pada jenjang dan jenis pendidikan harus diselenggarakan secara inspiratif, interaktif, memotivasi peserta didik untuk berpartisipasi aktif, memberikan ruang gerak yang cukup untuk berprakarsa, mengembangkan kreativitas dan kemandirian sesuai dengan bakat, minat, perkembangan fisik dan psikologis peserta didik.

Introduction: Pediatric patients with coronavirus disease 2019 (COVID-19) account for less than 5% of
the total incidence. The scientific literature reports that most patients are asymptomatic or present mild
symptoms. However, they may only manifest gastrointestinal symptoms and even present an acute
abdomen; a severe form of presentation has been reported, called multisystem inflammatory syndrome in
children.
Case Presentation: We report a 10-year-old girl who presents COVID-19 in the form of an acute abdomen
because of severe sigmoiditis who developed multisystem inflammatory syndrome together with shock. The
patient fully recovered without sequelae with medical treatment. We provide computed tomography and
ultrasound images and review scientific information available on gastrointestinal COVID-19
pathophysiology from the pediatric point of view.
Conclusion: A high index of suspicion is needed for diagnosing COVID-19 in the event of any pediatric
acute abdomen during the pandemic, and screening should be undertaken even without an epidemiologic
setting and in the absence of respiratory symptoms or radiologic chest signs because acute abdomen could
be a clinical presentation of MIS-C in children.
