Identification of 7 Movements of the Human Hand Using sEMG - 360° on the Forearm
Authors:   , Ibarra-Fuentes A.
Published: December 2021

This document shows the identification of 7 gestures (movements) of the human hand from sEMG – 360° signals in the forearm. sEMG – 360° is the sEMG measurement through 8 channels every 45° making a total of 360°. When making a hand gesture, there will be 8 independents sEMG signals that will be used to identify the movement. The 7 gestures to identify are: relaxed hand (closed), open hand (fingers extended), flexion and extension of the little finger, the ring finger, the middle finger, the index finger and the thumb separately. 100 samples of each of the gesture were captured and 3 feature extractors were applied in the time domain (mean absolute value (MAV), root mean square value (RMS) and area vale under the curve (CUA)), then a vector support machine (SVM) classifier was applied to each extractor. The movements were identified and the percentage of accuracy in the identification was calculated for each extractor + SVM classifier. The calculation of the percentage of accuracy took into account the 8 channels for each gesture. 97.61 % accuracy was achieved in the identification of human hand gestures by applying sEMG – 360°.
Hybrid methodology using balancing optimization and vibration analysis to suppress vibrations in a double crank-rocker engine
Authors: Albaghdadi Anwr , Baharom Masri , Sulaiman Shaharin
Published: December 2021

This study aims to present mathematical modelling to evaluate and analyze double crankrocker engine performance. The study suggests the use of two methods to reduce system vibration through balancing optimization and vibrational analysis. The combination of both methods acts as a verification method; besides it can be used as a tool for further system design enhancement and condition monitoring. The derived mathematical model is then used for balancing optimization to identify system shaking forces and moments, while variable speed is considered as an added parameter to evolve the optimization process. This factor shows better enhancement in reducing system shaking forces and moments compared to constant speed balancing method. Next, the system characteristics were concluded in terms of mode shapes and natural frequencies using modal and frequency response analysis, which give clear clue for secure system operational ground. Finally, the reduction in system vibrations was translated into engine’s centre of mass velocity, which evaluates balancing process effectiveness and indicate if further enhancement should be conducted.
The Relevance of Language as a Predictor of the Will for Independence in Catalonia in 1996 and 2020
Authors: Argelaguet Jordi
Published: December 2021

The Catalan secessionist parties, if added together, have won all the elections to the Parliament of Catalonia from 2010 to 2021. Their voters have been increasingly mobilized since the start of the controversial reform process of the Statute of Autonomy (2004–2010). The aim of this article is twofold. First, it intends to test whether language is the strongest predictor in preferring independence in two separate and distinct moments, 1996 and 2020. And second, to assess whether its strength has changed—and how—between both years. Only the most exogenous variables to the dependent variable are used in each of two logistic regressions to avoid problems of endogeneity: sex, age, size of town of residence, place of birth of the individual and of their parents, first language (L1), and educational level. Among them, L1 was—and still is—the most powerful predictor, although it is not entirely determinative. The secessionist movement not only gathers a plurality of Catalan native speakers, but it receives a not insignificant level of support among those who have Spanish as their L1. Conversely, the unionist group, despite being composed primarily by people who have Spanish as their L1 and have their family origins outside Catalonia, has a native Catalan-speaking minority inside. This imperfect division, which is based on ethnolinguistic alignments—and whose relevance cannot be neglected—alleviates the likelihood of an ethnic-based conflict.
Justifying Secession in Catalonia: Resolving Grievances or a Means to a Better Future?
Authors: Elias Anwen , Franco-Guillén Núria
Published: December 2021

This article advances understandings of secessionist strategies by examining how and why secessionist movements make the case for creating a new sovereign state. It draws on new empirical data to examine the ways in which pro-independence parties in Catalonia have justified their calls for the creation of an independent Catalan Republic between 2008 and 2018. The findings challenge the widespread scholarly assumption that secessionist mobilisation is underpinned by grievances—cultural, economic, and political—against the state. We find that arguments for an independent Catalonia rarely include cultural claims. Instead, independence is advocated as a way of resolving political and economic grievances and of creating a better, more democratic, and just Catalan society. Such justifications are highly influenced by the political context in which pro-independence parties try to advance towards secession. These insights advance on extant explanations of secessionist mobilisation by highlighting the distinctive nature of, and the motives for, secessionist claims.
Preferences in Between: Moderates in the Catalan Secessionist Conflict
Authors: Balcells Laia , Kuo Alexander
Published: December 2021

Recent research on territorial preferences focuses on explaining who supports or opposes independence. However, this research overlooks the relevance of an “intermediate” category of citizens who may oppose the territorial status quo of a sub-state territory but not support independence. We use evidence from the critical case of Catalonia to illustrate the relevance of individuals with such preferences for policies and outcomes highly relevant to secessionist conflicts. We present four sets of findings using two-wave panel data from December 2017 (just prior to the December regional elections when Catalan independence was the most salient and contentious issue) and September 2018. First, we find that a sizable plurality within Catalonia supports greater autonomy short of independence; conventional sociodemographic variables explaining support for independence do not strongly account for this preference. Second, such pro-autonomy individuals have considerably more intermediate attitudes regarding the key “on the ground” actions that the Spanish and Catalan governments pursued during the crucial independence drive in 2017. They were more opposed than pro-independence individuals to the unilateral independence efforts, and more opposed than pro-status quo individuals to the Spanish government’s actions to counter these efforts. Third, they expressed emotions around the secessionist conflict similar to pro-status quo individuals. Finally, using an embedded survey experiment, we find that pro-autonomy individuals are more trusting of both the central and regional governments regarding their abiding by an agreement to resolve the conflict, and are less easily “polarized” through priming. Overall, these findings indicate the importance of further analyzing individuals with intermediate territorial views in secessionist conflicts.
The Asymmetrical Effect of Polarization on Support for Independence: The Case of Catalonia
Authors: Rodríguez-Teruel Juan , Barrio Astrid
Published: December 2021

The article analyses the consequences of elite polarization at the mass level in the centre-periphery dimension. We analyse the rapid rise in support for independence in Catalonia, focusing on the role of party competition around the centre-periphery cleavage. We argue that mainstream actors’ adoption of centrifugal party strategies with respect to the national question produced a polarizing dynamic in the party system that eventually caused voters’ attitudes regarding the centre-periphery issue to harden. Indeed, we posit that this increase in mass polarization was a consequence of party agency that subsequently helped to drive attitudes regarding independence. To test this hypothesis, we measure centre-periphery polarization (as perceived by voters) by adopting two different perspectives—inter-party distances (horizontal polarization) and party-voter distances (vertical polarization)—and then run logistic regressions to explain support for independence. The findings show an asymmetrical effect on polarization. While the centrifugal strategy implemented by Catalan regionalist parties paved the way for a radicalization of voters on the Catalan nationalist side, among voters for non-regionalist parties, attitudes towards independence were initially less conditioned by this polarization. The results provide evidence of the political effects of elite polarization.

Purpose of the study. Exploring the erythrocyte glutathione system functioning in patients with gastric cancer in a comparative aspect, depending on tumor histotype and disease prevalence.

Patients and methods. The study included 89 patients with gastric cancer, divided into 6 groups depending on the histotype of the tumor. Separately, the results of the study were analyzed in patients with T4 status according to TNM and in patients at stage 4. The content of reduced glutathione and the activity of glutathione-dependent enzymes in the erythrocytes of the patients' blood were studied by conventional spectrophotometric methods. Statistical processing of the results was carried out using the Statistika 6.0 software package according to the Student's t-test and the nonparametric Wilcoxon-Mann-Whitney test for two independent samples.

Results. An increase in the content of glutathione was revealed in patients with gastric cancer compared with the group without oncopathology. The maximum increase was observed in patients with low-grade adenocarcinoma - by 42.5 %, while in signet ring cell carcinoma (SRCC) there was only a tendency to increase by 17.8 %. Glutathione reductase activity was decreased in adenocarcinoma by 23.4-26.2 % and did not change in SRCC. The activity of the antioxidant enzymes glutathione peroxidase and glutathione transferase was increased in all groups, and especially in SRCC - by 76 % and 23-29 %, respectively. In patients with the T4 status and at stage IV of the process, a lower activity of the studied glutathione-dependent enzymes was revealed in comparison with all other groups of patients.

Conclusions. The data obtained indicate a greater functional potential of the glutathione system in SRCC. A significant increase in glutathione transferase activity at a sufficiently high level of reduced glutathione can contribute to the development of treatment resistance in SRCC patients.

Published: December 2021

Purpose of the study. To evaluate the antitumor efficacy of liposomal doxorubicin hydrochloride in combination with tamoxifen in the treatment of breast cancer.

Materials and methods. The study included mongrel white rats (n = 30). A model of carcinogenesis (Walker 256 tumors) was created for all animals. Then we divided these rats into 3 equal groups: 1 control group (n = 10) - animals were monitored without treatment; 2 group (n = 10) - animals received neoadjuvant therapy: liposomal doxorubicin hydrochloride + cyclophosphan; 3 group (n = 10) - animals received neoadjuvant therapy with doxorubicin hydrochloride (non-liposomal) and cyclophosphan. Animals of the second and third groups received two cycles of neoadjuvant therapy. All animals were monitored for 1.5 months. We evaluated the effectiveness of antitumor therapy by measuring the size of tumors, the dynamics of their regression, and counting the number of metastases in the lungs. The toxic effects of doxorubicin hydrochloride were assessed by blood parameters: platelet and lymphocyte levels.

Results. We recorded a significant inhibition of the growth of tumor nodes in the second group of rats on the 25th day from the start of the experiment compared with the first and third groups: 36004.7, 86112.1 and 38962.4 mm3, respectively. By the end of the 3rd week of the experiment, we also noted the formation of a tumor regression trend in the 2nd and 3rd groups of animals, which was reliably maintained until the end of the observation. At the end of the experiment, the number of metastases in the first group of animals was 3 times more, in the third group almost 1.5 times more than in the second (p < 0.05)

Conclusion. The treatment of Walker 256 tumor with liposomal doxorubicin showed better efficacy and safety in comparison with non-liposomal doxorubicin. The tumor volume becomes smaller against the background of neoadjuvant chemotherapy with liposomal doxorubicin hydrochloride compared with its non-liposomal form, while there is no pronounced decrease in platelets and lymphocytes. We also recorded a significantly lower number of lung metastases in animals of the second group compared to other groups.

Published: December 2021

Aim. To improve surgical treatment outcomes of patients with spontaneous rupture of the esophagus complicated by purulent mediastinitis.

Methods. Over the past 30 years, we have experience in the surgical treatment of 31 patients with spontaneous rupture of the esophagus complicated by purulent mediastinitis. Depending on the tactics and techniques of surgical treatment, we identified two groups of patients. The first group (n=8) consisted of patients operated with conventional techniques: thoracotomy, transpleural mediastinotomy according to Dobromyslov, suturing of the esophagus with drainage of the mediastinum and pleural cavities, blind mediastinal drainage. The second group (n=23) consisted of patients treated with programmed re-thoracotomy. Re-thoracotomy was performed along with the postoperative thoracotomy wounds. The delimited foci of purulent mediastinitis were opened and sanitized (necrotic tissues were excised and removed). Preventive hemostatic methods were used in the area of pressure ulcers from drainage tubes. Replacing and changing the position of the drainage tubes in the mediastinum was a strictly compulsory technique. Pus and necrotic soft tissue that appeared in the thoracotomy wound were subsequently eliminated by a device consisting of two titanium brackets connected by a lock embodied in the form of an oval ring during the wound suturing at the stage of programmed re-thoracotomy. The groups were comparable in age and comorbidities. The average diagnosis of spontaneous esophageal rupture took 3.5 days; the maximum time is 10 days. The statistical significance of differences in immune status indicators was assessed by using the Student's t-test and Pearson's 2 test.

Results. A systematic approach using the tactical and technical surgical techniques developed by us (such as suturing esophageal wall defects regardless of the rupture time, multifunctional nasoesophagogastric tube installation; the imposition of a purse string suture to prevent reflux from the stomach into the esophagus; programmed re-thoracotomy using the method of temporary fixation of the ribs) allowed to reduce the number of complications, such as haemorrhage from the mediastinal vessels, by 3 times, sepsis 1.5 times, mortality almost 2 times.

Conclusion. The introduction of patented techniques allowed to reduce the number of life-threatening complications and mortality in patients with spontaneous rupture of the esophagus complicated by purulent mediastinitis.

The differential diagnosis of paroxysmal conditions, as well as disorders of muscle tone (hypertension) in the neonatal period and in young children is quite complicated. Various states of the nervous system in newborns are transient and permanent, optimal and suboptimal, normal and pathological. Among them, we can mention non-epileptic paroxysmal states of early childhood. In some cases, non-epileptic paroxysmal states of early childhood is accompanied by motor disorders, manifested by an excessive increase in limb tone in newborns. This pathological condition of muscle tone in the English-language literature is referred to by the term stiffness baby (the syndrome of a rigid or fettered baby). Neonatal pathological muscle hypertonicity, unlike physiological hypertonicity of muscles of a newborn, is a rather rare condition. The article presents literature data and a description of the clinical observation of a patient with hyperekplexia. Hyperekplexia is a rare paroxysmal movement disorder in young children. The main clinical variants of the disease, methods of diagnosis and correction, the main mutations associated with this condition are considered. The article describes the own clinical observation of an early-age patient with hyperekplexia, its clinical picture, features of paroxysmal states and therapy, neuroimaging data, electroencephalographic phenomena recorded in the patient and genetic testing that confirmed the diagnosis of non-epileptic paroxysmal disorders. The child has a mutation in the ATAD1 gene associated with type 4 Hyperekplexia (618011).

Published: December 2021

Objective: The aim of this study is to explore the role of nutritional nursing in the quality of life, nutritional status, and complications in elderly uremic patients receiving peritoneal dialysis (PD). Methods: We enrolled 205 uremic patients who were treated with PD in our hospital
from March 2018 to April 2019 as the research subjects. Then we grouped them according to different nursing methods: 116 cases receiving nutritional nursing were assigned to the research group (RG) while the other 89 cases receiving routine nursing to the control group (CG). Clinical biochemical
markers were detected by the biochemistry analyzer, the nutritional status determined by the Modified Quantitative Subjective Global Assessment (MQSGA), the anxiety and depression intensity assessed by Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS), the sleep quality
assessed by the Pittsburgh Sleep Quality Index(PSQI), the nursing satisfaction level assessed by the hospital’s self-made nursing satisfaction questionnaire, and the quality of life evaluated by the Quality of Life Questionnaire (QLQ-C30 ). The complication rate in patients was monitored.
Results: The improvement of clinical biochemical markers after nursing was better in RG than in CG. The decrease in the MQSGA score, SAS score, SDS score, and PSQI score after nursing was sharper in RG than in CG. Compared with CG, RG had a remarkably lower complication rate, a notably higher
nursing satisfaction level, and a remarkably better quality of life. Conclusion: Nursing intervention for elderly uremic patients receiving PD can enhance the quality of life of patients, improve the nutritional status, promote the recovery from the disease, and reduce the complication rate.

Published: December 2021

We introduce two large open data collections of Indian Art Music, both its Carnatic and Hindustani traditions, comprising audio from vocal concerts, editorial metadata, and time-aligned melody, rhythm, and structure annotations. Shared under Creative Commons licenses, they currently form the largest annotated data collections available for computational analysis of Indian Art Music. The collections are intended to provide audio and ground truth for several music information research tasks and large-scale data-driven analysis in musicological studies. A part of the Saraga Carnatic collection also has multitrack recordings, making it a valuable collection for research on melody extraction, source separation, automatic mixing, and performance analysis. We describe the tenets and the process of collection, annotation, and organization of the data. We provide easy access to the audio, metadata, and the annotations in the collections through an API, along with a companion website that has example scripts to facilitate access and use of the data. To sustain and grow the collections, we provide a mechanism for both the research and music community to contribute additional data and annotations to the collections. We also present applications with the collections for music education, understanding, exploration, and discovery.

In this work, the introduction of modifying additives in the composition of catalysts is considered as an effective mode of improving functional characteristics of materials for two processes of methane conversion into valuable products – methane dehydroaromatization (DHA of CH4) into benzene and hydrogen and autothermal reforming of methane (ATR of CH4) into synthesis gas. The effect of type and content of promoters on the structural and electronic state of the active component as well as catalyst activity and stability against deactivation is discussed. For DHA of CH4 the operation mode of additives M = Ag, Ni, Fe in the composition of Mo-M/ZSM-5 catalysts was elucidated and correlated with the product yield and coke content. It was shown that when Ag serves as a promoter, the duration of the catalyst stable operation is enhanced due to a decrease in the rate of the coke formation. In the case of Ni and Fe additives, the Ni-Мо and Fe-Mo alloys are formed that retain the catalytic activity for a long time in spite of the carbon accumulation. For ATR of CH4, the influence of M = Pd, Pt, Re, Mo, Sn in the composition of Ni-M catalysts supported on La2O3 or Ce0.5Zr0.5O2/Al2O3 was elucidated. It was demonstrated that for Ni-M/La2O3 catalysts, Pd is a more efficient promoter that improves the reducibility of Ni cations and increases the content of active Nio centers. In the case of Ni-M/Ce0.5Zr0.5O2/Al2O3 samples, Re is considered the best promoter due to the formation of an alloy with anti-coking and anti-sintering properties. The use of catalysts with optimal promoter type and its content provides high efficiency of methane valorization processes.
Los troles de patentes: una historia de exceso de ejercicios de derechos de propiedad intelectual
Authors: Bonadio Enrico , Contardi Magali
Published: December 2021

Un “trol de patentes” es una entidad que obtiene una serie de patentes sin llevar a cabo investigación y desarrollo, por ejemplo, adquiriéndolas en el mercado, y sin ninguna intención de trabajar las invenciones subyacentes produciendo y/o comercializando productos. Más bien, estas entidades se dirigen a otras empresas de las cuales simplemente sospechan que utilizan la invención patentada, amenazándolas con demandarlas por infracción de patentes y obligándolas a corresponder cánones (a menudo bastante elevados), incluso cuando la infracción de la patente en cuestión es incierta. Este artículo analiza este fenómeno desde la perspectiva del derecho de patentes estadounidense, adoptando una postura crítica del comportamiento abusivo por parte de algunas entidades no practicantes. De allí que el artículo toma como punto de partida el pleito estadounidense Blackbird contra Cloudflare, iniciado por un bufete de abogados boutique que es conocido por haber interpuesto más de 50 acciones de infracción de patentes contra entidades diferentes en un solo año.
Trans*-Subjectivity: Exploring Research Positionality in the Field
Authors: Whitley Cameron T.
Published: December 2021

The focus on trans*1 individuals as researcher subjects often problematizes trans* identity, limiting the possibility for trans* individuals to create and co-create bodies of knowledge. Drawing on three years of participatory research in the animal production industry, I discuss the implications of my subjectivity as a trans* man in this particular setting and in my research more broadly. Beyond being a self-reflexive exercise, this study seeks to make a number of theoretical and empirical contributions. First, feminist literature discussing one’s subjectivity has largely focused on the dialectical existence between men and women, with little room for trans* or gender diverse perspectives. Further, studies that have acknowledged trans* identity have done so in relation to trans* persons as research subjects, with no recognition of their positionality or the possibility of the trans* researcher. This study seeks to change these paradigms by extending current feminist research frameworks on subjectivity to include greater gender diversity.

Published: December 2021

This paper empirically examines the impact of foreign direct investment on economic growth in the East Africa Community throughout 1970-2017. The study used Pedroni test of cointegration for testing long-run relationship and VECM to inspect the long- run and short-run Granger causality between FDI and economic growth. The paper confirmed the integration of order one among the variables at the first difference. The results from Pedroni cointegration and VECM found that FDI is statistically significant and positively associated to economic growth in East Africa Community country members. The gross capital formation also is affirmative and statistically noteworthy connected to economic progress in the region, while inflation and Population growth were found as statistically significant and negatively correlated with economic, and thus, government final consumption expenditure and trade respectively are negatively and positively statistically insignificant. The VECM Granger causality exploration discovered the bi-directional Granger causality between GDP per capita and population growth rate; FDI and population growth rate, and gross capital formation and population growth. As well, unidirectional Granger causality was found among some variables. On the policy perspective, the study recommended the EAC members to strengthen the foreign direct investment policy through inducements to investors, availability of basic infrastructure, and establishment of the better macroeconomic environment.

Published: December 2021

The COVID-19 pandemic has prompted educational leaders to restructure the curriculum and modify the instructional set-up to accommodate remote learning of which using technology is the most viable solution to the existing problem. This study explores how teachers adapt and utilise technology-based teaching, and what makes students learn under blended learning modalities in Taytay Senior High School. Quantitatively, using the validated survey questionnaire anchored on the technology adaptation model and the adaptive learning environment model, this study revealed that teachers' age is the factor in all aspects of the model (performance and effort expectancy, social influence and facilitating conditions). When comparing the adaptation levels of students and teachers, it showed that teachers were slightly higher than the students, and that there is a negligible correlation. The findings of this study will serve as baseline data for immediate actions for items that surfaced concerns as hindrance or factors that can hamper students’ academic performance.

Published: December 2021

O aterramento elétrico é parte fundamental das instalações elétricas e do sistema elétrico como um todo. De modo a assegurar o bom desempenho do aterramento, ele deve ser adequadamente projetado e, para isso, uma etapa fundamental é a medição de resistividade e estratificação do solo. Nesse sentido, este artigo compara diferentes procedimentos para modelagem do solo a partir de medições com o método a quatro eletrodos. São comparados o método convencional de Wenner e um novo método, que utiliza um novo fator geométrico de modo a estimar com maior exatidão a resistividade do solo para o caso de pequenos espaçamentos. Para a comparação, o método dos elementos finitos é aplicado para a elaboração de estudos de caso. Inicialmente, o desempenho de ambos os métodos é comparado para a estratificação de um solo de duas camadas. Em seguida, são analisadas as diferenças que os métodos de modelagem do solo exercem sobre a resistência de aterramento calculada para o caso de eletrodos simples, dos tipos haste vertical e cabo horizontal. Constata-se que o método proposto fornece resultados mais precisos, permitindo modelar com maior exatidão a resistividade da camada superficial do solo. O método convencional de Wenner, se aplicado com espaçamentos menores que 1,0 m, resultou em maiores que 20% para alguns dos casos analisados. Com o fator geométrico proposto, o erro máximo foi de 2,0%.

La instalación de cables para conexión entre equipos de subestaciones eléctricas, se diseñan considerando cargas debidas a corto circuito, peso propio, viento, entre otras, no obstante, omiten condiciones adicionales según la instalación final o excluyen cargas, como las presentes en zonas de alta actividad sísmica, aspectos que complementarían el cálculo de deformación del cable, por otro lado, se suele desconectar el esfuerzo de diseño en los modelos 3D, ya que estos únicamente emplean los puntos de anclaje y “splines” para definir su trayectoria. Conocer la deformación aproximada del cable es importante para la verificación de distancias de seguridad eléctricas, minimizando posibles inconvenientes en la fase de construcción. Este documento, presenta la integración de diversos modelos de cargas para cables, en una representación de elementos finitos con SAP2000, incluyendo condiciones finales de instalación y cargas sísmicas según IEEE 1527, garantizando estabilidad de conexión, distancias de seguridad eléctricas e integridad de equipos. Adicionalmente, se conectan los resultados de deformación con una aplicación desarrollada en Dynamo-Python para complementar el modelo BIM en Revit. La metodología se valida según casos de conexión documentados por el Pacific Earthquake Engineering Research Center (PEER), el cual registra medidas de deformación para cables empleados en subestaciones eléctricas bajo diferentes escenarios de carga e instalación. Con la integración propuesta, se obtienen deformaciones esperadas ante desplazamientos bajos, presentando un mejor ajuste de trayectoria y cálculo de esfuerzos según los reportados por PEER, no obstante para desplazamientos altos, se obtienen diferencias representativas en los esfuerzos medidos, aspecto por mejorar.

Os principais defeitos em para-raios estão comumente associados a elevações de corrente e, por isso, ao aquecimento por efeito Joule. Assim, a termovisão nestes equipamentos é uma técnica adequada para a detecção de defeitos. Porém, tal uso da termovisão depende de um operador experiente para interpretar os resultados obtidos, sujeitando o processo a erros de interpretação. Diante disso, este trabalho tem como objetivo aplicar técnicas de Inteligência Artificial na classificação de imagens térmicas de para-raios como forma de tornar o processo mais confiável. Foram desenvolvidos algoritmos de inteligência artificial baseados em técnicas de Redes Neurais Artificiais e deep learning, tendo em vista que muitos autores obtiveram sucesso na utilização destes métodos no diagnóstico de falhas em outros equipamentos do sistema elétrico de potência.  Os resultados obtidos mostraram que as redes neurais desenvolvidas pelo método backpropagation apresentaram uma boa eficiência ao classificar imagens de para-raios e que não há necessidade de segmentar o para-raios da imagem termográfica para realizar a classificação.
Nelojalna partnerska ponašanja na društvenim mrežama: doprinos osobina ličnosti i samoprezentacije neverstvu i obraćanju pažnje na alternative

Društvene mreže predstavljaju kontekst u kom se aktivno uspostavljaju i razvijaju intimni odnosi. Zbog specifičnosti onlajn interakcije, društvene mreže su pogodno okruženje u kom se ispoljavaju i razna nelojalna partnerska ponašanja. U ovom radu ispitivane su determinante obraćanja pažnje na alternativne partnere i neverstva na društvenim mrežama, a cilj je bio da se ispita doprinos narcizma, traženja senzacija i samoprezentacije navedenim oblicima nelojalnog partnerskog ponašanja. Uz to, ispitivan je medijatorski efekat samoprezentacije i obraćanja pažnje na alternative na relaciju između osobina ličnosti i neverstva. U istraživanju su učestvovale 423 osobe koje su trenutno u intimnoj vezi (22.2% muškog pola, prosečna starost 22, raspon godina od 18 do 52 godine). Rezultati pokazuju da narcizam, traženje senzacija i samoprezentacija na društvenim mrežama daju unikatni doprinos predikciji obraćanja pažnje na alternative, dok je neverstvo unikatno povezano samo sa samoprezentacijom. Relacija narcizma i neverstva potpuno je posredovana samoprezentacijom i obraćanjem pažnje na alternative, dok je odnos traženja senzacija i neverstva posredovan samo obraćanjem pažnje na alternative. Nalazi ovog istraživanja sugerišu da je opravdano praviti konceptualnu razliku između obraćanja pažnje na alternative i neverstva, kao i da ova ova dva oblika nelojalnog partnerskog ponašanja mogu biti motivisana različitim psihološkim potrebama.
Foodomics: Advances in product testing in agri-food supply chains
Authors:   Royal Agricultural University, UK, Manning Louise
Published: December 2021

This chapter is written to describe the concept of product testing in agri-food supply chains and the methods that are being developed to identify instances of product non-conformance with either regulatory requirements, market requirements or both. The emergence of a range of new technologies provides opportunity to build on existing product testing protocols and offer complementary alternative and rapid testing of food which can provide assurance that food products are consistently what they are purported to be. Microbiological contamination will not be considered in this chapter. Effective and targeted product testing also acts as a potential deterrent against food safety incidents and food fraud. The chapter also introduces the term “foodomics” and what this means in terms of smart agri-food supply chains.

New measurement technologies are facilitating new approaches to the improvement of safety and quality in agri-food supply chains. However, measurement uncertainty and choice of sampling strategy can influence the outcomes of assessment programmes. This chapter provides a sampler of calculations of population statistics, required sample sizes and approaches to developing and implementing a sampling strategy. While examples from the fresh produce sector are given, the sampler is of relevance to both the student and the practitioner operating in agri-supply chains more generally.
Smart post-harvest technology to maintain quality and safety in fresh produce supply chains
Authors:   Harper Adams University, UK, Monaghan James
Published: December 2021

In this chapter the main challenges for the postharvest management of fresh produce are summarised. Key areas where the use of new smart technologies can improve crop management are explored, starting with how environmental sensors can be integrated into internet of things (IoT) systems with potential for use in the fresh produce supply chain. The next section summarises how the implementation of low oxygen storage environments is being refined through the use of dynamic controlled atmosphere systems incorporating sensor technologies. Modified atmosphere packaging and the developing field of active and intelligent packaging for fresh produce is then discussed. The chapter ends with future options for how smart technologies may develop in this sector.

For the substance under the code DAB-21, a pronounced neuropsychotropic potential was previously shown. In this study, possible directions of the influence of the studied substance on basic mediator systems of the CNS are considered. According to the results of the study, a benzodiazepine-like effect of DAB-21 was found in the «Elevated plus maze» test with flumazenil, as well as potentiation of the effects of phenamine, and some serotoninergic effect in the test with 5-GTP, and a weak a2-adrenoblocking effect, revealed using the «Clofelinic hypothermia» test. There was also a D2-activating effect according to the haloperidol test, a weak M-anticholinergic effect in the arecoline test. Some MAO-inhibitory effect was found, suggested by antagonism with reserpine, as well as the results of the L-DOPA test. The compound did not interact with nicotine and apomorphine. The neurotransmitter profile of the compound DAB-21 is of interest for further study and clarification of the mechanism of action of the substance.
