The diagnostic potential of cone beam computed tomography for cervical spine injuries in children: a review of two reports
Authors: Erenkov Il'ya O. , Voronin Vadim A.
Published: July 2023

Compared to multiaxial computed tomography, the cone beam computed tomography has its benefits in terms of higher resolution imaging, including the construction of a 3D image, and in terms of several fold lower radiation exposure. The duration of scanning of less than 1 minute and the possibility to place a patient in the sitting position allow for the use of this method in various fields of stomatology, maxillofacial surgery, as well as in traumatology for the assessment of limb injuries.
The paper presents our experience with the cone beam computed tomography as a single method for radiation diagnostics in children with cervical spine injuries. The first case is an example of the use of this method for primary diagnosis and subsequent follow-up of the restoration of the atlantoaxial position in a 9-year old child with rotatory subluxation of the atlant. To clarify the type of the injury, we combined and compared the axial planes of the 1st and 2nd cervical vertebrae. In the second case, we explored the possibility to assess the restoration of the bone structure and mutual position of the upper cervical vertebrae with the images obtained by cone beam computed tomography in a 9-year old girl with the Down's syndrome, who had been operated due to a cervical spine injury.
The analysis of the cone beam computed tomography images from the first clinical case delineates the prospects of the method in the diagnostics of the atlant rotation subluxation in school-age children. Evaluation of the images obtained during the examination of the second clinical case has identified some disadvantages of the cone beam computed tomography, namely: 1) there is no way to control the fixed patient position, 2) limitations of the software to suppress artifacts arising from the metal construction, which leads to advanced image blurring and flatness, significantly hindering the identification of abnormalities.
Lima satirizada (1598-1698) : Mateo Rosas de Oquendo y Juan del Valle y Caviedes
Authors: Lasarte Pedro
Published: July 2023

Aproximación crítica a las obras satírico-burlescas de estos dos primeros escritores del Perú. Partiendo de la premisa de que el género satírico -por su naturaleza dialógica- elude una visión unívoca de la realidad, y se escapa de expresiones autobiográficas, este libro nos entrega una visión más directa de las complejidades y contradicciones por las que pasaba la sociedad limeña en un lapso de cien años que se inicia con la aparición de la obra del primer satírico (1598) y se cierra con la muerte del segundo (1698). En constante diálogo con la tradición literaria europea, estos dos autores recontextualizan un sinfín de conocidos tópicos satíricos en el esapcio de Lima y sus habitantes para recuperar una ideología peruana que operaba a espaldas, y a veces en contra de las instituciones del Perú virreynal.

Background: Information on gene action governing yield and yield component traits need to be studied for adoption of effective breeding procedure to wards development and isolation of high yielding promising lines from the cross with resistant to bacterial leaf blight, blast and tolerance to low soil phosphorous. The present investigation was taken up in this context to estimate the gene effects for yield and yield components of the cross, YH3 x AKDRMS 21-54, using five parameter model of generation mean analysis. Methods: The experimental material, P1, P2, F1, F2 and F3 generations, for the investigation was generated from Kharif 2019 onwards and evaluated at Agricultural College, Bapatla during Rabi 2021-22. Gene effects for grain yield and yield attributing traits were studied. Result: Mean effects of all traits studied were significant indicating the presence of sufficient variation for the traits. Significance of scaling tests revealed additive-dominant model as inadequate, indicating the presence of epistasis. Digenic non-allelic interaction model with five parameters, namely, m, d, h, i and l revealed that the epistatic interaction model was adequate to explain the gene action for the traits studied in the present investigation. Dominance x dominance gene interaction was pre-dominant for grain yield per plant and majority of yield component traits studied coupled with duplicate epistasis, indicating the importance of population improvement approaches, such as bi-parental mating and recurrent selection, followed by isolation of purelines in later generations of the cross for effective improvement of yield and majority of the yield component traits.

Reog art has become the identity of the Ponorogo district. Paguyuban Singo Mudo in Sidoharjo village, Ponorogo regency, is the only one that preserves the unique local wisdom of reog, namely reog dadak lar pitik. This reog was made because the community in Sidoharjo had difficulty getting peacock feathers and tiger skin as basic reog ingredients, so they were replaced with dadak lar pitik and civet skin. Then reog dadak lar pitik is believed to be a tradition to bring rain. This research aims to analyze the values of religious moderation in the local wisdom of reog dadak lar pitik. This research was conducted using a qualitative approach with ethnographic methods. The data collection tools were observation sheets, interview sheets, documentation, and Forum Group Discussion (FGD). The findings are first, preserving local culture can be seen in people who still uphold the reog dadak lar pitik performance as a means of bringing rain. Second, tolerance is seen in people who still respect the opinion of the belief that this reog can bring rain, even though many people no longer believe it. The third is the absence of conflict of belief, whether those who believe in the myth of reog dadak lar pitik can bring rain, because this reog was used as a means of da'wah. Fourth, patriotism is depicted in the characters of the reog actors who have a patriotic spirit. Kesenian reog menjadi identitas kabupaten Ponorogo. Paguyuban singo mudo di Desa Sidoharjo, kabupaten Ponorogo satu satunya yang melestarikan kearifan lokal reog yang unik yaitu reog dadak lar pitik. Reog dadak lar pitik dibuat karena masayarakat di Sidoharjo kesulitan mendapatkan bulu merak dan kulit harimau sebagai bahan dasar reog sehingga diganti dengan dadak lar pitik dan kulit musang. Kemuadian reog dadak lar pitik dipercaya sebagai tradisi untuk mendatangkan hujan. Tujuan penelitian ini untuk menganalissis nilai-nilai moderasi beragama dalam kearifan lokal reog dadak lar pitik.  Penelitian ini dilaksanakan menggunakan pendekatan kualitatif dengan metode etnografi. Alat pengumpul data menggunakan lembar observasi, lembar wawancara, dokumentasi, dan Forum Group Discussion (FGD). Temuan penelitian ini pertama melestarikan budaya lokal tampak pada masyarakat yang masih memegang teguh pertunjukan reog dadak lar pitik sebagai sarana mendatangkan hujan. Ke dua, toleransi terlihat pada masyarakat yang tetap menghargai pendapat kepercayaan bahwa reog dadak lar pitik dapat mendatangkan hujan, walaupun banyak masyarakat yang sudah tidak percaya. Ke tiga perdamaian tampak dari tidak adanya konflik kepercayaan baik yang percaya dengan mitos reog dadak lar pitik dapat mendatangkan hujan atau tidak, karena reog dadak lar pitik dijadikan sarana dakwah. Ke empat, patriotisme tergambarkan pada tokoh-tokoh pemeran reog yang memiliki jiwa patriotisme.
Islamization Process of The Tellumpoccoe Alliance: The History of Bone, Soppeng and Wajo

Published: July 2023

This research was conducted on the basis of the lack of research that specifically reveals the process of Islamization of the Tellumpoccoe alliance based on historical facts available in the field. This study aims to reveal the process of Islamization of three major regions which include Bone, Soppeng, and Wajo. This study used a historical research method consisting of heuristics/collection of historical sources, external and internal criticism of historical sources, interpretation, and historiography/or historical writing. The results demonstrate that the beginning of the arrival of Islam in South Sulawesi was received openly by two major kingdoms namely Luwu in 1602 and Gowa in 1605. After the Kingdom of Gowa embraced Islam, the existence of an Ulu agreement between the Bugis-Makassar kings caused the Kingdom of Gowa to try spreading the religion of Islam peacefully but was rejected because of the suspicion of political motives to control other kingdoms. In response to this matter, a Telumpoccoe alliance was established by three kingdoms namely Bone, Soppeng, and Wajo to stem the invasion effort as well as the process of Islamization carried out by the Kingdom of Gowa. However, such great power possessed by the Kingdom of Gowa caused the failure of this alliance to maintain its existence. In the end, each kingdom that was incorporated into the alliance embraced Islam, namely Soppeng in 1609, Wajo in 1610, and Bone in 1611.Penelitian ini dilakukan dengan dasar masih kurangnya penelitian yang mengungkapkan secara spesifik terkait proses islamisasi aliansi Tellumpoccoe berdasarkan fakta-fakta historis yang tersedia di lapangan. Penelitian ini bertujuan untuk mengungkap proses islamisasi tiga daerah besar yang meliputi Bone, Soppeng dan Wajo. Penelitian ini menggunakan metode penelitian historis yang meliputi heuristik/pengumpulan sumber sejarah, kritik eksternal maupun internal terhadap sumber sejarah, interpretasi dan historiografi/atau penulisan sejarah. Hasil penelitian menunjukkan bahwa awal kedatangan Islam di Sulawesi Selatan diterima dengan terbuka oleh dua kerajaan besar yaitu Luwu pada tahun 1602 dan Gowa pada tahun 1605. Setelah kerajaan Gowa memeluk Islam, adanya perjanjian Ulu Ada antara raja-raja Bugis-Makassar menyebabkan Kerajaan Gowa mencoba menyiarkan agama Islam secara damai, akan tetapi ditolak karena adanya kecurigaan adanya motif politik untuk menguasai kerajaan lainnya. Sebagai respons terhadap hal tersebut, maka didirikanlah persekutuan Telumpoccoe oleh tiga kerajaan yaitu Bone, Soppeng dan Wajo guna membendung usaha invasi sekaligus proses islamisasi yang dilakukan oleh Kerajaan Gowa. Akan tetapi, kekuatan begitu besar yang dimiliki oleh Kerajaan Gowa menyebabkan kegagalan aliansi ini untuk mempertahankan eksistensinya. Pada akhirnya masing-masing kerajaan yang tergabung dalam aliansi tersebut memeluk Islam, yaitu Soppeng pada tahun 1609, Wajo tahun 1610, dan Bone pada tahun 1611.

Published: July 2023

22 Temmuz 1926-22 Nisan 1927 tarihleri arasında Cumhuriyet gazetesinde 155 sayı tefrika edilen Harabeler; aşka, kadın-erkek ilişkilerine, sosyal ve kültürel hayata odaklanan bir İstanbul romanıdır. “Yunus Nadi Beyefendi”ye ithaf edilen roman; Kadıköy, Beyoğlu ve Büyükada’nın eğlence mekânlarını, İstanbul sosyetesinin yaşam tarzını işler. Yazarın diğer eserlerinde olduğu gibi aşk ve kadın romanın merkezini oluşturur. Ancak Harabeler’in yazarın diğer romanlarından ayrılan yönü, sosyal eleştiriye de yer vermesidir. Eserde, Cumhuriyet sonrası yaşanan toplumsal değişimlere, alafrangalığın yozlaştırıcı yönlerine, Batılılaşmanın sosyal ve kültürel hayat üzerindeki etkisine dikkat çekilir. Batı merkezli bir eğitim sürecinden geçmiş olan roman başkişisi Nuri Süha’nın bakış açısından anlatılan olaylarda özellikle sosyal ve kültürel hayatta yaşanan değişimler, Cumhuriyet ile birlikte farklılaşan yaşayış tarzı dikkat çekici bir şekilde işlenir. Bu çalışmada, romanda yer alan toplumsal çözülme ve değişimler ele alınmış, romandan yapılan alıntılarla Mehmet Rauf’un bu eserinde sadece aşk ve kadın konusunu işlemediği ortaya konulmuştur. Böylece yazarın daha çok bilinen Halâs adlı romanı gibi Harabeler’in de aşk ve eğlence hayatının dışında sosyal ve millî meselelere yer veren bir roman olduğu tespit edilmiştir.

Authors: William Andre , Novanto Yusak
Published: July 2023

“Life satisfaction” is an individual’s cognitive assessment of the quality of their life. One factor that influences life satisfaction is the meaning of work. The “meaning of work” is a person’s broad perspective of his work. This study investigates whether there is a significant effect of the meaning of work on the life satisfaction of Confucian ministers in Indonesia. This quantitative research was conducted with a linear regression research design on 81 active Confucian ministers throughout Indonesia. The measurement tools used in this study are the Work as Meaning Inventory (WAMI) to measure the meaning of work and the Riverside Life Satisfaction Scale (RLSS) to measure life satisfaction. The results of this study found that the meaning of work had a significant effect of 18.4% on the life satisfaction of Confucian ministers. In addition, it was also found that the dimension of meaning-making through work has the greatest influence on life satisfaction. Based on these results, it is suggested that leaders of Confucian ministers to make better regulations for their organizations to improve the life satisfaction of their ministers by focusing on their perceived meaning of work.
Geometrized Vacuum Physics. Part II. Algebra of Signatures
Authors: Batanov-Gaukhman Mikhail
Published: July 2023

This article is the second part of a scientific project under the general name "Geometrized vacuum physics". On the basis of the Algebra of Stignatures presented in the previous article [1], this article develops the main provisions of the Algebra of Signatures. Both of the above algebras are aimed at studying the properties of an ideal vacuum, but at the same time they are universal and can be applied in various branches of knowledge. It is shown that the signature of a quadratic form is related to the topology of the metric space for which the given quadratic form is a metric. Conditions are given under which an additive imposition of metric spaces with different topologies (or signatures) leads to a total Ricci flat space similar to a Calabi-Yau manifold. A spin-tensor representation of metrics with different signatures is considered and a Dirac bundle of quadratic forms is presented. This article does not contain physical applications of the Algebra of Signatures, but the potential power of this mathematical apparatus will be demonstrated in subsequent articles of this project.

The creation of crop-type maps from satellite data has proven challenging, often impeded by a lack of accurate in-situ data. This paper aims to demonstrate a method for crop-type (ie. Maize, Wheat and Other) recognition based on Convolutional Neural Networks using a bottom-up approach. We trained the model with a highly accurate dataset of crowdsourced labelled street-level imagery. Classification results achieved an AUC of 0.87 for wheat, 0.85 for maize and 0.73 for other. Given that wheat and maize are the two most common food crops globally, combined with an ever-increasing amount of available street-level imagery, this approach could help address the need for improved crop-type monitoring globally. Challenges remain in addressing the noisy aspect of street-level imagery (ie. buildings, hedgerows, automobiles, etc.), where a variety of different objects tend to restrict the view and confound the algorithms

Published: July 2023

Traditional numerical techniques such as sliding mesh, dynamic grid mesh, and others, have many limitations in dealing with flow simulation with large-scale movement of solid boundaries; which is the case for complex-shaped hydraulic turbomachinery such as propellers, pumps and turbines. The immersed boundary (IB) method provides a new approach to solve the above limitations. Therefore, this study proposes an sharp-interface IB method based on the level-set function that is suitable for simulating the flow through turbomachinery with complex geometries. This method is applied to actual three-dimensional numerical simulations of high-Reynolds number propellers using an in-house computational fluid dynamics solver. The results show that the proposed method can provide comparatively accurate predictions of unsteady load coefficients within the propeller flow passage, and capture the correct propeller wake characteristics as well as the interaction between the propeller wake and free surface. This study aims at providing a theoretical basis and engineering reference for the application of the IB method in engineering numerical simulations.

Published: July 2023

This study investigated the mechanical properties and fatigue behavior of FH36 steel plate rolled in different directions. By adopting a sequential rolling process in the rolling direction (RD) and transverse direction (TD), the differences in properties between RD and TD were eliminated, resulting in nearly identical tensile properties. The steel plate exhibited a yield strength of approximately 420 MPa, a tensile strength of approximately 506 MPa, and an elongation of approximately 25%. Fatigue tests conducted at room temperature and -60℃ showed a fatigue limit of the maximum stress of 488 MPa at room temperature and 500 MPa at -60℃, indicating improved low-temperature fatigue performance. The fracture surfaces displayed distinct characteristics, such as oblique shearing fractures for high-cycle fatigue and cup-cone shape fractures for low-cycle fatigue. The fatigue source zone were both on the surface of the specimens. As the maximum stress increased, the area of the crack propagation zone for high-cycle fatigue decreased, while the area of the final fracture zone, the number of dimples and the proportion of the LAGBs increased.

Published: July 2023

Aedes aegypti transmits major arboviruses of public health importance, including dengue, chikungunya, Zika, and yellow fever. The use of insecticides represents the cornerstone of vector control, however insecticide resistance in Ae. aegypti has become widespread. Understanding the molecular basis of insecticide resistance in this species is crucial to design effective resistance management strategies. Here, we applied Illumina RNA-Seq to study the gene expression patterns associated with resistance to three widely used insecticides (malathion, alpha-cypermethrin and lambda-cyhalothrin) in Ae. aegypti populations from 2 sites (Manatí and Isabela) in Puerto Rico (PR). Cytochrome P450s were the most over-expressed detoxification genes across all resistant phenotypes. Some detoxification genes (CYP6Z7, CYP28A5, CYP9J2, CYP6Z6, CYP6BB2, CYP6M9, and two CYP9F2 orthologs) were commonly over-expressed in mosquitoes that survived exposure to all three insecticides (independent of geographical origin) while others including CYP6BY1 (malathion), GSTD1 (alpha-cypermethrin), CYP4H29 and GSTE6 (lambda-cyhalothrin) were uniquely overexpressed in mosquitoes that survived exposure to specific insecticides. The gene ontology (GO) terms associated with monooxygenase, iron binding, and passive transmembrane transporter activities were significantly enriched in 4 out of 6 resistant vs susceptible comparisons while serine protease activity was elevated in all insecticide resistant groups relative to the susceptible strain. Interestingly, cuticular-related protein genes (chinase and chitin) were predominantly downregulated, which was also confirmed in the functional enrichment analysis. This RNA-Seq analysis presents a detailed picture of the candidate detoxification genes and other pathways that are potentially associated with pyrethroid and organophosphate resistance in Ae. aegypti populations from PR. These results could inform development of novel molecular tools for detection of resistance-associated gene expression in this important arbovirus vector and guide the design and implementation of resistance management strategies.

Published: July 2023

In order to reduce the environmental damage caused by coal waste landfills, it is necessary to look for rational ways of their management. One of the methods of their development may be the creation of soil-like substrates. The aim of the study was to assess the properties of soil-like substrates from coal mining waste with a varied share of sewage sludge and waste mineral wool. The evaluation of the properties of the substrates was carried out in a pot experiment. The properties of the substrates and their yield potential were determined. Coal mining waste as a substrate, compared to anthropogenic soil, was characterized by: significantly higher sorption capacity, content of alkaline cations and pH, significantly higher content of organic carbon, nitrogen and assimilable forms of K and Mg, and lower content of assimilable P. The substrates enriched with sewage sludge showed: significant increase in the content of organic carbon, nitrogen and assimilable forms of P and Mg, optimization of sorption properties. Extending the composition of substrates with mineral wool resulted in further improvement of their properties. Yields of plants grown on coal mining waste were significantly lower than on anthropogenic soil. Substrates with sewage sludge and mineral wool had a significantly higher yield potential.
Theoretical Interpretation of pH and Salinity Effect on Oil in Water Emulsion Stability Based on Interfacial Chemistry and Implications for Produced Water Demulsification
Authors: Amadu Mumuni , Miadonye Adango
Published: July 2023

The petroleum industry produces thousands of barrels of oilfield waters from the initial stage driven by primary production mechanisms to the tertiary stage. These produced waters contain measurable amounts of oil in water emulsions, the exact amounts being determined by the chemistry of the crude oil. To meet strict environmental regulations governing the disposal of such produced waters, demulsification to regulatory permissible levels is required. Within the electric double layer theory, coupled with the analytical solutions to the Poisson Boltzmann Equation, continuum electrostatics approaches can be used to describe the static and electrokinetic properties of such emulsion systems. Therefore, theoretical understanding of the stability of oil in water emulsions within such fundamental concepts provides reliable approaches to demulsification. In this paper, we have used theoretical approaches, based on zeta potential and surface charge density models to determine the stability of oil in water emulsions for different crude oil samples. Accordingly, we have used literature based data on the chemistry of the crude oils, and have ranked the order of emulsion stability based on criterial established by zeta potential plots for the oil. Our theoretical calculations show that where the isoelectric points of crude oil samples are closer to each other, the degree of ionization plots versus pH indicate close tends for salinities at varying pH of oilfield waters. Based on the chemistry of crude oil samples, the most efficient and cost-effective means of demulsification is by reducing produced water pH to values closer to the average point of zero charge pH values
On-the-Go Vis-NIR Spectroscopy for Field-Scale Spatial-Temporal Monitoring of Soil Organic Carbon
Authors: Reyes Javier , Ließ Mareike
Published: July 2023

Agricultural soils serve as crucial storage sites for soil organic carbon (SOC). Their appropriate management is pivotal for mitigating climate change. To evaluate spatial and temporal changes in SOC within agricultural fields, continuous monitoring is imperative. In-field data sets of Vis-NIR soil spectra were collected on a long-term experimental site using an on-the-go spectrophotometer. Data processing for continuous SOC prediction involves a two-steps modelling approach. In Step 1, a Partial Least Square (PLSR) regression model is trained to establish a relationship between the SOC content and the spectral information also including spectral preprocesisng. In Step 2, the predicted SOC content obtained from the PLSR models is interpolated using ordinary kriging. Among the tested spectral preprocessing techniques and semivariogram models, SG and gapDer preprocessing along with a Gaussian semivariogram model, yielded the best performance resulting in a root mean square error of of 1.24 and 1.26 g kg-1. A striping effect due to the transect-based data collection was addressed by testing the effectiveness of extending the spatial separation distance, employing data aggregation, and defining the distribution based on treatment plots using block kriging. Overall, the results highlight the immense potential of on-the-go spectral Vis-NIR data for field-scale spatial-temporal monitoring of SOC.
A Survey on Industrial Internet of Things Security: Requirements, Attacks, AI-based Solutions, and Edge Computing Opportunities
Authors: Alotaibi Bandar
Published: July 2023

The Industrial Internet of Things (IIoT) paradigm is a key research area derived from the Internet of Things (IoT). The emergence of IIoT has enabled a revolution in manufacturing and production, through the employment of various embedded sensing devices connected with each other by an IoT network, along with a collection of enabling technologies such as artificial intelligence (AI) and edge/fog computing. One of the unrivaled characteristics of IIoT is the inter-connectivity provided to industries; however, this characteristic might open the door for cyber-criminals to launch various attacks. In fact, one of the major challenges hindering the prevalent adoption of the IIoT paradigm is IoT security. Inevitably, an increasing number of research proposals have been introduced over the last decade to overcome these security concerns. To obtain an overview of this research area, conducting a literature survey of the published research is necessary, eliciting the various security requirements and their considerations. This paper provides a literature survey of IIoT security, focused on the period from 2017 to 2023. We identify IIoT security threats and classify them into three categories, based on the IIoT layer they exploit to launch these attacks. Additionally, we characterize the security requirements that these attacks violate. Finally, we highlight how emerging technologies, such as AI and edge/fog computing, can be adopted to address security concerns and enhance IIoT security.

The connection between marital status and suicidal behavior has been poorly assessed in South Asia. We aimed to see the proportion of marital status in individuals in suicidal behavior in South Asian countries. We followed PRISMA guidelines and registered the protocol in advance (PROSPERO 2023 CRD42023399906). A systematic search was conducted in Medline, Embase, and PsycINFO. Meta-analyses were performed to pool the proportion of married individuals with suicidal behavior (total, suicide, and suicide attempt) in South Asian countries. Our search identified 47 studies for this review from six countries published from 1999 to 2022 with a sample size ranging from 27 to 89178. The proportion of married individuals was 55.4% (95% CI 50.1-60.5) for suicidal behavior, 52.7% (95% CI 44.5 – 60.7) for suicides, and 43.1 (95% CI 32.9 – 53.9) for suicide attempts. The proportion of married persons among suicide attempts varied significantly across countries (p=0.016) which was highest (61.8%; 95% CI: 57.2 – 66.2) in India, followed by Bangladesh (52.5%; 95% CI 41.8% - 62.9%) and Pakistan (45.1%; 95% CI 30.9 – 59.9). As the current study did not assess any cause-and-effect association, a cautious interpretation is warranted while considering married marital status as a risk factor.
A New Definition of Dual Spline Curves for Curve Modeling and Geometry Defeaturing
Authors: Chi Baotao , Bai Shengmin , Guo Qianjian , Zhang Yaoming , Yuan Wei , Li Can
Published: July 2023

The present paper provides a new definition for dual spline curves in a geometric intuitive way based on adaptive curve refinement techniques. The dual spline is an implementation of the interpolatory subdivision scheme for curve modeling, which is comprised of polynomial segments of different degrees. Specially, the dual spline curves are mainly aims to solve the difficult geometry defeaturing problems in the existing computer-aided technology. Dual spline curves maintain various desirable properties of conventional curve modeling methods, such as local adaptive subdivision, high interpolation accuracy and convergence, continuous and discontinuous boundary approximation. By adding fictitious and intrinsic nodes inside or at the vertices of interpolation elements, the dual spline is flexible and convenient for approximating a set of ordered points or discrete segments. Combined with the Lagrange interpolation polynomial and meshless method, the proposed approach is capable of approximating the non-smooth boundary for geometry defeaturing. Experimental results are given to verify the validity, robustness, and accuracy of the proposed method.

The purpose was to reflect on the sustainability of artisanal and informal mining in the Peruvian Andean zone by 2022. The type of research was basic, non-experimental design, ex post facto scope. The sample consisted of: statistics on crime prevention due to socio-environmental conflicts from the National Prosecutor's Office and the Ombudsman's Office, reports of interventions targeted at artisanal and informal miners. The procedure focused on gathering secondary information for a documentary review analysis that is based on proven and disseminated past facts. Artisanal and informal mining is strengthened in the Peruvian Andean zone by incidence and force: 1) the social license and agreements by community assembly, 2) the flexibility in compliance with the formalization, preventive and environmental protection laws, 3) the 50% increase in socio-environmental conflict due to mining activity, 4) a 25% progressive increase in the production costs of agricultural and livestock activities. The direct consequences on environmental sustainability are: 1) the delimited reconversion of the change in agricultural land use in a third of the communal territories in basin headwaters; 2) displacement of environmentally friendly economic activity by 20% in basin headwaters; 3) the impossibility of modification or intervention in water surfaces, bofedales by communal agreements.
The Optical Properties and Spectroscopic Limited Maximum Efficiency of SnO2 Polymorphs for Solar Cell Applications: A First-Principles Analysis
Authors: Balakrishnan Kanimozhi , Veerapandy Vasu , Ponniah Vajeeston
Published: July 2023

Considering the significant interest in the synthesis and various properties of the polymorphs of tin dioxide (SnO2), they are still comparatively rare in modern photovoltaic techniques. The hybrid organic-inorganic lead perovskites have triggered a revolution among solar cell researchers due to their low cost and ultrahigh power conversion efficiency. In this research, the optical properties of seven stable polymorphs (Balakrishnan Kanimozhi et al. ACS omega 7, 12 (2022): 10382-10393) of SnO2 have been investigated using first-principles approaches. The effective mass of stable SnO2 polymorphs has been computed and it is found to vary depending on the specific polymorph and the direction in which it is measured. Moreover, the spectroscopic limited maximum efficiency (SLME) of SnO2 polymorphs was also computed and compared to that of other efficient perovskite solar cells. Both Pnnm and Pbca have equivalent efficiency in comparison to the rutile polymorph. Three of the seven stable polymorphs are effective in solar cell applications. This study is the very first attempt to examine the atomic structure and electronic properties of various SnO2 polymorphs using X-ray absorption near-edge spectroscopy (XANES) at both the Sn-K-edge and O-K-edge wavelengths. Our findings, as mentioned in this paper, may be an important advancement in the understanding of these materials, thereby facilitating the development of more efficient photovoltaic devices.

The paper analyzes quasiperiodic upwellings and downwellings on the shelf and upper part of continental slope of the north-eastern Black Sea. It is shown that these processes are related to changes in intensity and direction of alongshore current and the following geostrophic adjustment of density field. The source of such changes is a meandering of the Black Sea Rim Current (RC). It leads to a quasi-periodic change of direction of the alongshore current, from north-western (cyclonic RC meander) to south-eastern (anticyclonic RC meander, or eddy). These cycles, or phases, have average duration about 10 days. During the north-western phase, the permanent Black Sea pycno-halocline (hereafter pycnocline) and seasonal thermocline descend, their thickness increases, and so does the thickness of the upper mixed layer (UML). During the south-eastern phase both pycnocline and seasonal thermocline ascend and become thinner, along with the UML, which also becomes thinner. In both phases, isopycnals in the pycnocline and isotherms in the thermocline demonstrate quasi-in-phase vertical oscillations, which have a good correlation with speed and direction of the alongshore current. These correlations allow estimation of the magnitude of upwellings and downwellings in the shelf-slope area of the north-eastern Black Sea using data series of current velocity profiles.

Forest damage has become more frequent in Europe in the last decades, and remote sensing offers a powerful tool for monitoring them rapidly and cost-effectively. A novel approach was developed to utilize high-resolution ESA Sentinel-2 satellite imagery and Google Earth Engine cloud computing. The processing, analysing, and visualization of vegetation and water index (NDVI, NDVIch, Z NDVI, EVI, NDWI) maps and charts derived from satellite images took place in the cloud to ensure the detection of forest disturbances in the Hungarian study site for the period 2017-2020. The index maps were classified to reveal forest disturbances, and the cloud-based method successfully showed drought and frost damage in the oak-dominated Nagyerdő forest of Debrecen. Differences in the reaction to damage between tree species were visible in the index values, therefore a Random Forest Machine Learning classifier was applied to show the spatial distribution of dominant species. Accuracy assessment was accomplished with confusion matrices that compared classified index maps to field-surveyed data, demonstrating 71% Total Accuracy for forest damage and 76% for tree species. Based on the results of this study and the resilience of Google Earth Engine, the presented method has the potential to be extended to monitor the entire Hungary.

Published: July 2023

In this paper, we present a new stress calculation method for flexible structures, particularly, the tensile armors, and apply it to flexible riser fatigue analysis. The method is based on a 3-dimensional curved bar theory. First, the tensile armor center line was described as a cylindrical helix curve, its bended curve length and bending migration length were derived and studied under different friction scenarios. Second, the tensile and bending stiffness was given with consideration of frictional hysteretic effect, and verified through FEA analysis results. Third, we presented the stress calculation formula for tensile armor under tension and bending load. All stress components are considered, including tensile, bending and shear stresses. Fourth, the method was benchmarked with published experimental results on a flexible prototype tension and bending tests, and comparisons showed general agreements. Fifth, the method is further applied to a 8” flexible riser for fatigue assessment and lifetime extension evaluation, and showed the flexible riser has sufficient remaining fatigue life, and is suitable to continue its service under the current operating conditions. Last, conclusions are drawn. It concluded that the presented tensile armor stress calculation method and modelling techniques are valid for flexible riser fatigue analysis. This method is time efficient, and can be implemented into other multi-scale models for riser dynamic analysis. It is also applicable to other similar helix structure stress analysis, such as wire ropes, submarine hoses, and subsea umbilicals.
Spontaneous Self-Affirmation and Student-Specific Stress: Relationships with Overlapping Constructs of Positive Self Regard During the COVID-19 Pandemic
Authors: Nicklin Anna , Morgan Jim
Published: July 2023

Background: Student-specific stress is pervasive and impairs health and attainment. Experimentally induced self-affirmation can reduce stress, but little is known about the mechanisms underlying this effect, and the role of individual differences. The present study explores the relationship between spontaneous self-affirmation, student-specific stress, and overlapping constructs of positive self-regard during the COVID-19 pandemic.

Methods: The study investigated inter-relationships between spontaneous self-affirmation, student-specific perceived stress and potential covariates including self-esteem, self-integrity and habitual positive self-thought. University students (N = 151) aged 18 to 50 responded to an online questionnaire including the Spontaneous Self-Affirmation Measure, College Student Stress Scale, Rosenberg Self-Esteem Scale, Habitual Index of Positive Thinking and Self-Integrity Scale.

Results: Unexpectedly, regression analysis revealed that spontaneous self-affirmation was a positive predictor of student-specific stress, seemingly driven by relational affirmations. Self-esteem and habitual self-thought were negative predictors of student-specific stress, whilst self-integrity was not a predictor.

Conclusions: Habitual positive self-thought may offer a sustainable solution to student-specific stress, but spontaneous self-affirmation does not. A reduction in defensive responses, elicitation of negative emotions, or use of conditional relationships in relational affirmation

Viruses are abundant and diverse entities that have important roles in public health, ecology, and agriculture. Identification and surveillance of viruses rely on understanding their genome organization, sequences, and replication strategy. Despite technological advancements in sequencing methods, our current understanding of virus diversity remains incomplete, highlighting the need to explore undiscovered viruses. Virus databases play a crucial role in providing access to sequences, annotations and other metadata, and analysis tools for studying viruses. However, there has not been a comprehensive review of virus databases in the last five years. This study aimed to fill this gap by identifying 24 active virus databases and included an extensive evaluation of their content, functionality and compliance with the FAIR principles. In this study, we thoroughly assessed the search capabilities of five database catalogs, which serve as comprehensive repositories housing a diverse array of databases and offering essential metadata. Moreover, we conducted a comprehensive review of different types of errors, encompassing taxonomy, names, missing information, sequences, sequence orientation, and chimeric sequences, with the intention of empowering users to effectively tackle these challenges. We expect this review to aid users in selecting suitable virus databases and other resources, and to help databases in error management and improve their adherence to the FAIR principles. The databases listed here represent current knowledge of viruses and will help aid users find databases of interest based on content, functionality, and scope. Use of virus databases is integral to gain new insights into the biology, evolution, and transmission of viruses, and develop new strategies to manage virus outbreaks and preserve global health.

The global prevalence of insulin resistance (IR) is increasing continuously, influencing metabolic parameters and fertility as well. The metabolic changes due to IR can alter the molecular composition of plasma and other body fluids. Follicular fluid (FF) is derived mainly from plasma, and it is a critical microenvironment for the developing oocytes. It contains various metabolites and amino acids, and the quality of the oocytes is linked at least partially to amino acid metabolism. Our goal was to determine quantitatively the amino acid (AA) profile of FF in IVF patients and to compare IR and non-insulin resistance (NIR) groups to investigate the AA changes in their FF. By UHPLC-based method we quantified the main 20 amino acids from human FF samples in the IR and NIR groups. Several amino acids (aspartate, glycine, glutamate, and cysteine) differed significantly (p<0.05 or less) between the two groups. The most significant alterations between the IR and NIR groups were related to the glutathione metabolic pathway involving glycine, serine, and threonine. Since insulin resistance alters the amino acid composition of the FF, the oocytes may undergo metabolism-induced changes resulting in poor oocyte quality and less fertility in the insulin resistance groups.

In the Formula Student Racing Car, the anti-deformation ability of the frame will affect the four-wheel positioning parameters of the racing car, and then affect the handling and stability performance of the racing car. The quality of the frame directly determines the power and economy of the racing car, so the performance of the frame is very important to the performance of the race. In order to improve the performance of the frame and reduce the total weight of the frame, the research on the lightweight design of the frame is particularly important. In this paper, based on the variable density method, the global topology optimization of the frame is carried out to obtain the distribution of the frame material, realize the efficient use of the material, and improve the torsional stiffness of the frame. Based on the adjoint variable method, the sensitivity analysis of the frame is carried out. According to the sensitivity analysis results, the size of the frame is optimized. The total mass of the frame is reduced by 12.8 %, and the performance of the maximum displacement and maximum stress is improved. The lightweight design of the frame is realized as a whole.
Towards Rigorous Diagnostics for Vaccine Injury
Authors: Halma Matthew
Published: July 2023

Delineating the epidemic of vaccine injury from the coterminous condition long covid is a challenging prospect, but one with many implications not just for treatment, but also has important legal considerations for settlements of vaccine injury. The shared etiological factor of the spike protein in both vaccine injury and long covid make differentiation difficult, and while treatment is largely similar between vaccine injury and long covid, there are important distinctions. Furthermore, diagnostics are important for monitoring treatment progress and assessing the extent of subclinical vaccine injury in population having received a covid-19 vaccine. The development of rigorous diagnostics is an important step towards the recognition of both long covid and vaccine injury, as those suffering these conditions have faced immense challenges in having their conditions recognized, treated, and compensated by insurance companies or national health services.
