On derivation of an invariant velocity and the Lorentz transformation using the principle of relativity
Authors: Ma Qing-Ping
Published: August 2022

Although traditional derivations of the Lorentz transformation rely on both postulates of relativity and constancy of the speed of light, some researchers have argued that linear transformations per se would naturally lead to a Lorentz type transformation with an unspecified velocity limit. The present study analyzes such a published derivation and shows that linear transformations do not naturally lead to invariant velocities. In the derivation analyzed by this study, in addition to its mathematic mistakes, its author’s interpretation of the derived results is also logically invalid. Its author and some researchers overlooked other consequences than the ones that appear to imply an invariant velocity or a velocity limit, when they were deriving parameters for linear transformations. Therefore, imposing at least two postulates is necessary for deriving the Lorentz transformation or its family of linear transformations. Linear transformations conforming to the principle of relativity alone are not sufficient to ensure a velocity limit or an invariant velocity.

Authors: Syaidah Nissa'atul , Faizah Silviana Nur
Published: August 2022

The shift from face-to-face learning to online learning during the COVID-19 pandemic has made printed teaching materials irrelevant. Teaching materials in online learning need to be designed to be more interactive in the form of electronic teaching materials in order to create two-way communication between teaching materials and students because online learning requires maximum learning autonomy from students. The irrelevance of existing teaching materials causes various learning problems in primary schools such as the teaching materials used do not encourage students' willingness to learn, some students experience learning backwards, and teachers need extra time to correct students' assignments. This study aims to develop electronic student worksheets based on Problem Based Learning (PBL) in primary schools. This development research refers to the ADDIE model as the model consists of systematic stages in an effort to solve learning problems according to the characteristics of the learner. The subjects of this study were 40 grade 3 students of Madrasah Ibtidaiyah (Islamic Primary School) Pembangunan Lamongan. The results showed 1) the validity of the electronic student worksheets in the very valid category based on the assessments of linguists, material experts, design experts, and learning experts, 2) The attractiveness of electronic student worksheets in the very interesting category. Based on the results of this study, the use of electronic student worksheets is appropriate to be used to support the thematic learning process.
Mitral Regurgitation and Serum N-Terminal Pro-Brain Natriuretic Peptide Levels in Children: A Modification of Adult Criteria
Authors: Erolu Elif , Akalin Figen
Published: August 2022

Mitral regurgitation can result from congenital heart disease, rheumatic valve disease, or other congenital malformations of the mitral valve. Faulty valves require surgical repair or replacement. However, echocardiographic and biochemical parameters that inform surgical decision-making for adults may not be appropriate for children. To investigate whether adult parameters can be used in children, we correlated echocardiographic parameters with serum N-terminal pro-brain natriuretic peptide (NT-proBNP) levels in children with chronic mitral regurgitation.

Our sample comprised 45 patients and 38 healthy children. M-mode measurements, left atrial and left ventricular volumes, and Doppler and tissue Doppler echocardiograms were collected. We graded mitral regurgitation according to European Association of Echocardiography recommendations and indexed effective regurgitant area, vena contracta, and regurgitant volume to body surface area. Patients were grouped by regurgitation severity (mild vs moderate or severe) and left ventricular end-systolic dimension (normal vs enlarged).

The NT-proBNP level was higher in patients than in controls (P=0.003), higher in patients with moderate or severe regurgitation (P=0.02), and higher in patients with an enlarged left ventricle (P=0.003). Serum NT-proBNP levels correlated with effective regurgitant area (r=0.47; P=0.002), vena contracta width (r=0.46; P=0.003), regurgitant volume (r=0.32; P=0.04), left ventricular end-systolic diameter (r=0.58; P <0.001), and left atrial diameter (r=0.62; P <0.001). An NT-proBNP value of 66 pg/mL differentiated the mild regurgitation group from the moderate or severe regurgitation group.

Our results correlating NT-proBNP and echocardiographic parameters indexed to body surface area indicate that these adult criteria can be used in children to grade mitral regurgitation and inform surgical decision-making.

The cost of COVID-19 services can be a burden in itself that can affect hospital budgets. Services for COVID-19 patients at RSUP dr. Kariadi has so far been running well and smoothly, but there is no detailed data and information regarding COVID-19 financing, the process of submitting a COVID-19 financing claim and its implications for finances and services as well as leadership policies at RSUP dr. Kariadi so that activities are needed to analyze the costs of COVID-19. The purpose of the study was to analyze the financing of COVID-19, the process of submitting a claim for COVID-19 and its implications for finance and services as well as leadership policies at RSUP dr. Kariadi. The research approach used in this research is descriptive. Collecting data through document observation and interviews. The sample was selected using simple random sampling and the sample size was using the Slovin formula. The results showed that there was a negative difference of Rp.-1,832,258.63 between the average real cost of COVID-19 services and those claimed for outpatients, and there was a positive difference of Rp.61,695,327.45 for inpatients. The difference is caused by the claim system using cost per day. The biggest real cost component is the cost of laboratory examinations. The process for submitting a COVID-19 claim is in accordance with applicable regulations and all submissions declared eligible and paid. From the results of the Chi-Square test, it can be seen that there is no relationship between age and real costs in inpatient care and vice versa in outpatient care, length of days of treatment affects real costs, there is a relationship between comorbidities and real costs in SL3 and SL2, and there is no the relationship between co-morbidities with real costs in SL1 and outpatient. COVID-19 has caused the number of hospital visits and revenues in general to decline. Hospital leadership implemented several policies in dealing with the implications of COVID-19, including shifting budget posts, controlling services, zoning services, limiting non-COVID-19 patient services, transferring facilities and infrastructure, and optimizing the claim process. The research results are expected to be used as input in policy making and budget planning.  Keywords: Financing Analysis, COVID-19

Induced mutagenesis by gamma rays plays a potent promising technology to be applied for crop improvement through breeding methods, especially in tiny florets possessing self- pollinated plants such as cereals. Finger millet (Eleusine coracana (L.) Gaertn.) which always ensured for valuable nutrients, as well as famine tolerant crop to supply food for global population throughout the year. The present study was performed to assess the spectrum and frequency of macro mutants induced by gamma radiations in M2 generation finger millet. The chlorophyll mutants viz., albina, xantha, chlorina and viridis and morphological mutants such as tall, dwarf, bushy, brittle stalk and broad leaf were recorded in different doses. Among the mutagen doses 600 Gy dose induced maximum increase in mean values and phenotypic and genotypic coefficients of variation for the plant height (cm), number of leaves per plant, leaf length (cm), number of tillers per plant, number of panicles per plant, panicle length, days to 50% flowering, and 1000 seeds weight. Except for panicle number/plant and 1000 seed weight, all traits showed high heritability in all doses. The results revealed a progressive decrease in mean values of quantitative traits with the increase in doses. The present study provides an idea about the optimum dose of gamma rays from a pool of doses that could be employed in future breeding programmes.

Published: August 2022

With the proposal of the concept of ubiquitous power Internet of Things and the further promotion of blockchain strategy, modern information technologies such as the Internet of Things and cloud computing have been widely used in the power system. While the power grid is becoming more intelligent, it is also accompanied by the emergence of various security threats, and the power grid will face greater challenges and pressures. In this paper, aiming at the current situation of information security faced by the power grid blockchain under the cloud Internet of Things, a multi-authorization center ciphertext policy attribute encryption access control method is constructed for the power grid blockchain. It adds the function of visitor attribute update revocation, aggregates multi-dimensional data into ciphertext, and uses CP-ABE encryption to implement fine-grained access control at the dimension level. Through experimental analysis, in terms of security and functionality, this method can resist physical collision attacks and manage access rights flexibly. In terms of encryption and decryption efficiency, the encryption and decryption calculation speed of the proposed method is 6.2–15.6% higher than that of the traditional method, and the time consumption efficiency is more than 5% higher than that of other methods. It proves that this model has more advantages for open network environments such as power grid blockchain with high confidentiality requirements and large scale of users. It is of great significance to study the data security and privacy protection methods of the power grid blockchain.

Published: August 2022

The potentials of CuZnAlNi shape memory alloys to serve as viable reinforcement in Aluminium matrix composites (AMCs) was investigated. The AMCs were double stir cast developed, containing 4, 6, and 8 wt% CuZnAlNi particles; and their structural characteristics and mechanical properties were compared with that of the unreinforced Al alloy and AMC containing 8 wt% SiC. Scanning electron microscopy and X-ray diffraction results show that the CuZnAlNi refined the grain size, and increase in the CuZnAlNi wt% resulted in the formation of varied AlCu-based intermetallics, apart from the primary Al rich phase. The strength indicators – hardness, ultimate tensile strength, and specific strength largely improved with increase in the CuZnAlNi wt% and were comparatively higher than that of the unreinforced Al alloy and AMC reinforced with 8 wt% SiC for the 6 and 8 wt% CuZnAlNi reinforced AMC (specific strength being the only exception). The percentage elongation and fracture toughness values of the AMCs reinforced with CuZnAlNi (12–14.5% and 10.5–12.3 MPa m1/2) were equally superior to the SiC reinforced AMC (9% and 6.5 MPa m1/2, respectively). However, a partial reduction in the % elongation was observed with the increase in the CuZnAlNi wt%. Improved matrix/particle interface bonding, matrix refinements, thermoelastic-induced compressive residual stresses, inherent ductile, and tough nature of the SMA were advanced as mechanisms responsible for the improvements in properties.
Unsicherheit der elektrischen Impedanzspektroskopie bei Schüttgütern
Authors: Bifano Luca , Fischerauer Gerhard
Published: August 2022

Während die prinzipielle Eignung der elektrischen Impedanzspektroskopie (EIS) zur Charakterisierung und Zustandsüberwachung von Materialsystemen gesichert ist, bestehen bei der Reproduzierbarkeit und der Unsicherheit von EIS-Messungen in Feldanwendungen vielfach noch Erkenntnislücken. Dies gilt besonders bei Schüttgütern - wir interessieren uns speziell für Gießereisande -, weil man Schwankungen bei der Schüttungsdichte oder der Befüllungshöhe von Messzellen erwarten darf. Wir haben diese offene Frage der Messunsicherheit mit einer Messzelle untersucht, bei der zwischen zwei planparallelen Elektroden wiederholt Schüttungen eingefüllt und die resultierende Impedanz der Anordnung in einem Frequenzbereich von 20 Hz bis 1MHz gemessen wurde. Die Unsicherheit der EIS-Gerätschaften an sich wurde über Wiederholungsmessungen bei gleichbleibender Messzellenfüllung bestimmt. Der Einfluss des Befüllungsvorgangs und damit der Schüttungszusammensetzung auf die Gesamtunsicherheit wurde über mehrmalige Befüllungs- Entleerungs-Zyklen mit ein und demselben Schüttgut untersucht. Es konnte gezeigt werden, dass die Gesamtmessunsicherheit klein genug ist, dass eine Klassifizierung verschiedener Sandzustände, sei es mit klassischen Methoden oder mit Hilfe von KI-Methoden, machbar erscheint.

Local and systemic effects of microbiome‐derived metabolites
Authors: Spivak Igor , Fluhr Leviel , Elinav Eran
Published: August 2022

Commensal microbes form distinct ecosystems within their mammalian hosts, collectively termed microbiomes. These indigenous microbial communities broadly expand the genomic and functional repertoire of their host and contribute to the formation of a “meta‐organism.” Importantly, microbiomes exert numerous biochemical reactions synthesizing or modifying multiple bioactive small molecules termed metabolites, which impact their host's physiology in a variety of contexts. Identifying and understanding molecular mechanisms of metabolite–host interactions, and how their disrupted signaling can contribute to diseases, may enable their therapeutic application, a modality termed “postbiotic” therapy. In this review, we highlight key examples of effects of bioactive microbe‐associated metabolites on local, systemic, and immune environments, and discuss how these may impact mammalian physiology and associated disorders. We outline the challenges and perspectives in understanding the potential activity and function of this plethora of microbially associated small molecules as well as possibilities to harness them toward the promotion of personalized precision therapeutic interventions.

As a case study, the application of SPT to a 3-year-old boy who struggled with his transition into kindergarten was cited. The differences in his emotions and behaviors before and after six sessions of SPT were evaluated, revealing that the intervention through SPT significantly decreased his anxiety level while increasing his willingness to attend nursery school and that he finally developed a sound adaptation to the school, according to the comments of the observers. Findings showed that SPT could help kids feel less nervous about starting kindergarten and adjust better to new situations.
Balancing hormones improves Type 2 diabetes
Authors: Sofra Xanya
Published: August 2022

Treating physicians have consistently recommended exercise to either prevent diabetes or de-escalate symptomatology. Diabetic complications render physical activity undesirable or unattainable. Diabetes has been often associated with hypothyroidism, weight gain, fatigue, accumulation of white adipose tissue, and inadequate supply of brown fat to generate energy. Accumulated toxicity results in hormonal imbalance, increased hunger, chronic pain, and wounds on extremities associated with diabetic neuropathy. Recent research with an effortless exercise method has demonstrated enhanced fitness and T3 increase, juxtaposed by decreased inflammation, an optimal relationship between leptin and ghrelin that control appetite, and a significant decrease of visceral fat along with VLDL, the very low-density lipoprotein that carries triglycerides to the tissues. This clinical trial measured triglycerides, metabolic efficiency as reflected by T3, inflammation level and fasting / postprandial glucose and insulin of 21 diabetics and 20 prediabetics respectively, pre and post twenty treatments. There was a statistically significant decrease in both fasting and postprandial glucose and insulin for all subjects who exhibited increased skeletal muscle mass, normalized T3 levels, decreased visceral and overall fat, and reduced CRP, advocating diminished inflammation. Dyslipidaemia appeared to subside as indicated by suppressed triglyceride levels contrasted by elevated HDL.

Published: August 2022

OBJECTIVES

To describe the epidemiology of battery-related emergency department (ED) visits among children aged <18 years in the United States from 2010 to 2019 and compare with previous study findings.

METHODS

Data on ED visits were obtained from the National Electronic Injury Surveillance System. Using narrative descriptions and diagnosis codes, battery-related cases were coded into four exposure routes: (1) ingestion, (2) mouth exposure, (3) ear insertion, and (4) nasal insertion.

RESULTS

An estimated 70 322 (95% confidence interval: 51 275–89 369) battery-related ED visits among children aged <18 years occurred during the study period, or 9.5 per 100 000 children annually. Button batteries were implicated in 84.7% of visits where battery type was described. A statistically significant increase in the ED visit rate occurred from 2010 to 2017 (P = .03), followed by a nonstatistically significant decrease from 2017 to 2019. The ED visit rate was highest among children aged ≤5 years compared with those 6 to 17 years (24.5 and 2.2 per 100 000 children, respectively). The mean patient age was 3.2 years (95% confidence interval: 2.9–3.4). Ingestions accounted for 90.0% of ED visits, followed by nasal insertions (5.7%), ear insertions (2.5%), and mouth exposures (1.8%).

CONCLUSIONS

Pediatric battery-related ED visit rates continued to significantly increase from 2010 to 2017, with children aged ≤5 years having the highest rates. Prevention efforts have not significantly reduced injury rates; therefore, regulatory efforts are needed. Ultimately, hazard reduction or elimination through safer button battery design is critical and should be adopted by the battery industry.
Inference and prediction of progressive Type-II censored data from Unit-Generalized Rayleigh distribution
Authors: WANG Liang , WU Ke , ZUO Xuanjia
Published: August 2022

In this paper, inference and prediction problems are studied under progressively Type-II censored data. When the latent lifetime follows the Unit-Generalized Rayleigh distribution, maximum likelihood estimators of the unknown parameters are established, and corresponding existence and uniqueness are also provided. Besides, the approximate confidence intervals are constructed based on asymptotic approximation theory. For comparison, another alternative generalized point and interval estimates are constructed based on proposed pivotal quantities. Further, point and interval predictions for the censored samples are established by using conventional classical and generalized inferential approaches. Finally, extensive simulation studies are carried out to investigate the performance of different methods, and one real-life example is presented to illustrate the applicability of the obtained results.

Published: August 2022

This article is devoted to the investigation of the influence of the solvent on sensing properties, such as response and recovery rate, of chemiresistive gas sensors. Multi-walled carbon nanotubes were used as an active material for the sensors. The initial material was investigated by scanning electron spectroscopy and transmission electron microscopy, low-temperature nitrogen adsorption, Raman spectroscopy, and X-ray diffraction. The active material was produced by drop casting. Different polar solvents (acetone and ethanol) were used for suspension preparation. Textolite with copper contacts on the edges of one side was used as a sensor substrate. The gas sensing properties (the response and the recovery time) were investigated in the range of 100–500 ppm NO2 at room temperature. The films made using different solvent suspensions showed high sensitivity and rapid recovery rate to nitrogen dioxide. It was found that the method of film preparation has an effect on the measured sensing properties. The films prepared using different suspensions possessed different properties: the film made from the acetone suspension had the response values from 8.49% to 20.26%, and the recovery values from 0.06%/min to 0.16%/min. The response of the film made from the ethanol suspension increased , being from 12.25% to 23.63%; the recovery rate were also increased (from 0.19%/min to 0.39%/min).
Chemical-mechanical treatment of potato starch for isolation of nanocrystal particles
Authors: Tryakhov Denis E. , Polytov Anatoly A.
Published: August 2022

Starch nanocrystals were isolated by a combination of acid hydrolysis and sonication of native potato starch. The obtained samples were examined by XRD, scanning electron microscopy and static light scattering. An increase in hydrolysis time increases the degree of crystallinity from 47 to 66%. By changing the processing conditions, it is possible to isolate particles of a given size. First, submicron flat particles with dimensions of 3000–5000 nm and a thickness of 80–100 nm are obtained. With longer processing, approximately isometric nanoscale particles remain. Based on the obtained data, a stepwise topochemical mechanism for the formation of starch nanoparticles was proposed.

Introduction: External resorptions often occur as a lesion of inflammatory origin. The origin of the process begins on the side of the root cementum and goes towards the pulp of the tooth. The changes consist of the pathological loss of root cement, dentin, and bone surrounding the tooth. The dynamics of the process are enhanced by inflammatory or necrotic pulp changes. Aims: This study aimed to present contemporary views on the resorption of external tooth roots and the possibility of their treatment. Material and methods: The technique of observation and clinical and radiological diagnostics were used by the case-by-case method Result: Endodontic treatment was undertaken, consisting of chemo-mechanical preparation of the canal system and simultaneous obturation of the gutta percha canals with the AH + sealant and the BL thermal system. Conclusions: The applied treatment inhibited the progression of the resorption and led to the healing of periapical periodontitis.

Hemophagocytic Lymphohistiocytosis (HLH) is a rare and potentially life-threatening syndrome related to a dysregulation of cytolytic function of Natural Killer (NK) cells and cytotoxic T cells (CTLs), which in turns leads to an inappropriate immune stimulation and hyperinflammatory state, resulting in hypercytokinemia, accumulation of activated lymphocytes and macrophages [1,2].

Aim: The study analyzed the nutrition and lifestyle of mothers related to air pollution in industrial and non-industrial regions, taking into account the economic situation of households. Methods: The respondents were a deliberate sample of mothers from two regions of the Czech Republic – districts of Ceske Budejovice (CB, N=376) and Karvina (KA, N=449). Selected districts were chosen for their difference in the air pollution, with CB being one of the least polluted and KA one of the most polluted regions/districts in the Czech Republic. Data were collected in maternity hospitals in the years 2019 and 2020. Results: The majority of respondents (98.5%) described their economic situation at least as average. They also consumed daily at least one hot meal. In Karvina mothers more often eat fish, poultry, legumes and also sweet meals and fried food than in Ceske Budejovice, where are more often consumed dairy products. Information about health risk are important for change of their habits. Conclusion: Most mothers in our study subjectively evaluated their economic situation as moderately good in both regions. Better economic situation was correlated with healthy nutrition, including higher consumption of fruits and vegetables, wholegrain bread, beef and fish and lower consumption of sweet drinks and produced meats. Notably the consumption of fruits and vegetables in the industrial region has risen in comparison with previous data, which is an improvement promising a better starting position for the new generation.
NCBI submission protocol for SARS-CoV-2 wastewater data: SRA, BioSample, and BioProject v2
Authors: Timme Ruth
Published: August 2022

PURPOSE: This method was developed at the FDA’s Center for Food Safety and Applied Nutrition for GenomeTrakr’s pandemic response project, monitoring SARS-CoV-2 variants in wastewater; however, this protocol was written to be broadly applicable for all wastewater sequence data submissions to NCBI. Protocols developed for this project cover wastewater collection, concentration, RNA extraction, RT-qPCR, library prep, genome sequencing, quality control checks, and data submission to NCBI. This protocol covers the last step of making your data public at NCBI. Specifically, it provides the steps to establish a new NCBI submission environment for your laboratory, including the creation of new BioProject(s) and submission groups. Once these are step up, the protocol steps through the process for submitting raw reads to SRA and sample metadata to BioSample through the Submission portal. For new submitters, there's quite a bit of groundwork that needs to be established before a laboratory can start its first data submission. We recommend that one person in the laboratory take a few days to get everything set up in advance of when you expect to do your first data submission. If you need a pipeline for frequent or large volume submissions, follow Step 1 in this protocol to get your NCBI submission environment established, then contact gb-admin@ncbi.nlm.nih.gov to set up an account for submitting through the API. Version updates: V2: minor edits to the BioSample and SRA templates V3: Adapted the protocol to be more broadly applicable to submitters outside of FDA's wastewater project. Updates were also made to both metadata templates, including a new attribute to the SRA metadata template, called "enrichment_kit". V4: updates to BioSample and SRA templates: expanded picklists, addition of specimen processing attributes for including replicate info, and the removal of target_extract attribute for reporting level of target found in the sample. V5: includes guidance for submitting BioSamples with no linked sequence data. V6: Updated templates. BioSample: added picklist for PCR concentration units. SRA: added new quality control attributes. V7: SRA and BioSample template updates V8: SRA template updates. "Illumina COVIDSeq Assay" added to library_preparation_kit, "QIAseq DIRECT SARS-CoV-2 - Boosted" added to amplicon_PCR_primer_scheme, "low coverage of characteristic mutations" added to quality_control_issues. minor edits to the protocol are also included in this update.
Beyond Solutionism: Differently Motivating Media Literacy
Authors: McDougall Julian , Rega Isabella
Published: August 2022

This article discusses three research projects conducted in partnerships in diverse societies. We assess the implications of each project for media literacy’s motivations and intentionality through a theory of change. For the first project, BBC Media Action, we developed the theory of change which frames this article and a media literacy training programme for in-country practitioners to strengthen media ecosystems and support resilience to information disorder. Our second project was Dual Netizenship, a youth-led, intercultural partnership between Tunisia and the UK at the intersection of media literacy, civic agency, and decolonisation. Thirdly, Digital Arts—Refugee Engagement (DA-RE) brought together refugee youth in Bangladesh and Turkey to combine media literacy and digital artivism with civic capability development. The status of media literacy as a conduit for positive change (rather than a solution in itself) was different in each partnership—from the production of counter-script youth-led media to capacity-building for refugee participants in host communities to the situating of “mainstream media” itself as the agent of positive intervention in the ecosystem. Our theory of change situates media literacy as a form of context-bound capability development as opposed to a set of neutral, universal competences. The research that we share here was conducted with “third space” media literacy design principles. In addressing both the positive change initiated by these projects and the tensions and challenges in play in the motivating imperatives of partnerships, the article speaks to the complexity of media literacy in diverse societies.
Acculturative Stress in International Students

Published: August 2022

Studying in a university is more challenging for international students as compared to local students. They are required to cope with the differences between their cultural values, norms, and customs and those of the host country. Many are likely to experience stress related to the acculturation process – termed acculturative stress. There was evidence of the direct effect of acculturative stress on students’ academic satisfaction and well-being. Also, past studies have confirmed the significant relationship between social support and acculturative stress, but these studies have predominantly focused on social support from family members and friends. The fact that international students live apart from their family members and friends means that they are heavily dependent on the support of the host university. This study investigated the effect of acculturative stress on students’ academic satisfaction and well-being, with university support as the moderating factor. The data is collected using questionnaires through various online mediums. A total of 119 responses were used in the analysis. By employing the Smart PLS software, we tested four hypotheses. From the findings, students from the African region reported the highest acculturative stress level, while students from the SEA region reported the lowest. Also, evidence of the direct effect of acculturative stress on students’ satisfaction and well-being was discovered, however the moderation effects of university support on both relations were not substantiated. We attributed this finding to the characteristics of the respondents who participated in this study.
