Authors: Evizal Rusdi , Prasmatiwi Fembriarti Erry
Published: October 2022

Agronomy examines complex agricultural production concepts such as Sustainable Agriculture, Good Agricultural Practices, Regenerative Agriculture into the best practical technologies that farmers can apply. Important agronomic variables in agricultural cultivation include production and productivity. Plant productivity is influenced by many interacting factors. This paper aims to examine the symptoms of decreased productivity and symptoms of degenerative agriculture. The decline in production and productivity that continues in the long term indicates a degenerative agro-ecosystem. Degenerative agriculture is an agricultural practice that causes productivity to continue to decline as a result of a decrease in the carrying capacity of agro-ecosystems, including soil, plants and other flora, fauna, microbes, climate and society. The decrease in the carrying capacity of the soil is shown, among others, by land degradation, a decrease in soil organism diversity and activity, declining of organic matter content and the availability of nutrients in the soil due to nutrient depletion transported by harvest, erosion and inappropriate cultivation practices. In addition, it will discuss the factors driving the degenerative agroecosystem that interact with each other. These factors include land degradation, decreased biodiversity, continuous planting of varieties and species of plants, use of chemical inputs, pest and disease attacks, and climate change. Mitigating these factors means choosing a path to regenerative agriculture. Key words : Agroecosystem, biodiversity, degenerative, sustainable, regenerative, productivity

The study of the insect distribution in geographical areas is relevant since it is important in terms of understanding the global trend of biodiversity decline. The paper presents the results of a study on the distribution of six species of Panorpidae (Mecoptera), carried out in 2008, 2009, 2011, 2015, 2017–2020. One part of data was collected by the authors. Other material was provided by colleagues from 11 regions in Russia. In European Russia, six species of Panorpa are reliably known, namely Panorpa alpina, P. cognata, P. communis, P. germanica, P. hybrida, and P. vulgaris. The most common and frequently encountered species are P. communis (in 21 regions), P. hybrida (in 12 regions), P. vulgaris (in 11 regions), and P. cognata (in 11 regions). It is assumed that all studied species can be found in other regions of European Russia as a result of further investigations. Among the studied species, P. alpina and P. germanica are the rarest species, recorded from two and one regions, respectively. Panorpa vulgaris was found for the first time in Russia.

Published: October 2022

Invasive species are a major threat to global biodiversity. One of the most effective invaders among freshwater snails is the North American ancyline gastropod Ferrissia californica (= fragilis). A new population of this species has been found in Lake Zerrouka (Northern Morocco), a Protected Area, which is also a site of ecological and biological interest (known as SIBE). Thus, this record expands the known distribution range of this invasive species in the Mediterranean area. Despite the fact it is located in only one out of more than 150 localities sampled by us, ongoing investigations could soon reveal more finds of the species in Morocco. Lake Zerrouka is known for recently described endemic snail species, i.e. Ifrania zerroukansis and Gyraulus marocana. Therefore, the monitoring of the presence and expansion of F. californica within invaded areas, as well as studies improving the knowledge on its biology and ecology is an urgent need.

Authors: Azkiya Aziz Mochamad Azkal , Ismail Shahrinaz , Allias Noormadinah
Published: October 2022

Conventional-manual type of attendance systems can be very time-consuming to some extent, particularly for a significant number. The existence of face recognition technology can solve the inefficiency and ineffectiveness of conventional and manual attendance systems. Among many approaches to implement face recognition, this research focuses on using deep learning approaches as it has been proven to give promising results. There are various algorithms for face recognition, such as Local Binary Pattern Histogram (LBPH), Local Binary Pattern Network (LBPn), Haar Cascade, and Convolutional Neural Network. The use of deep learning can reach 98 percent accuracy. However, it is necessary to conduct further research on its implementation on the real system in order to evaluate the efficiency of the system.Â  An interview was conducted with an expert in the field, to understand the concept, trend, and use of deep learning in face recognition, as well as to determine the suitable algorithm for the attendance system.Â  This paper presents the results from this interview, which provide an insight based on real practices.

A Systematic Literature Review: Optimization Timetable in Education to Support Work-Life Balance (WLB)
Authors: Yusop Noorrezam
Published: October 2022

Scheduling academic staff timetables is crucial and necessary to avoid redundancy and clash of class between teacher and student timetables. A good timetable allows students and teachers to manage their time and support a good and healthy lifestyle. However, with the scheduling, academic staff timetable may use many procedures to get efficient results. Therefore, this paper provides a gap of study for existing work on Optimization Timetable to support Work-Life Balance (WLB) regarding their market commercial and research purposes. The methodology of this study was conducted using a Systematic Literature Review (SLR). Result: two findings investigate 1) relevant optimization timetable scheduling used and 2) the method for timetable optimization to support WLB. The strengths and weaknesses of the features and utilities behind each study are also presented to provide a further understanding of the gaps and weaknesses of each body of research. We conclude that these studies are still insufficient and require further evaluation and improvement.

"The Impact of the Industrial Cultural Landscape’s Conversion through Tourism on the Environmental Elements of Ocna Mureș. The fulminant technological advance, corroborated with the increasing demand of products have favored, in the recent period, the accentuation of the various processes of environmental pollution, with particularly serious consequences on the living organisms. Thus, the European Green Pact is the instrument through which the European Union wants to establish the necessary steps to reduce air, water and soil pollution (by 2050), as the main elements of the environment affected by pollution. It is therefore recommended that the quality standards provided by the international forums be respected and that the specific legislation of all member states be aligned for a unified approach. In this regard, the implementation of the clean industrial technologies, recycling, the use of green energy in the production process, the use of natural resources in a sustainable manner or the conversion of industrial elements into tourism elements, can be viable means to achieve the goals proposed in the pact. In the context of those presented, this study seeks to argue the conversion of the industrial cultural landscape related to the exploitation and processing of local salt resources and the specific hazards, found at Ocna Mureș (Alba County), in the cultural and tourist-validated landscapes. The change of the function of the mentioned elements can favour the socio-economic revival of the area, with the observance of the new European environmental norms, in the medium and long term. Keywords: Ocna Mureș, salt resources, hazard, tourism, sustainable development, Industrial Cultural Landscape, conversion. "

Authors: GICĂ Oana Adriana , OLÁH Orsolya Iulia , BUTOI Elisabeta
Published: October 2022

The pandemic has significantly affected international tourism and in order to reach the level of travel recorded in 2019, a series of measures and strategies are needed that take into account the new perspective of tourists on travel. In this context, the primary purpose of this paper is to provide an analysis of the effect that COVID-19 has on travel activity preferences, subdividing the young tourists, and most important, how their travel behaviors changed following the pandemic. A questionnaire-based survey has been conducted on consumers of tourist services aged 18-29 years of various nationalities. The key topics investigated were the travel motivations, the criteria according to which they choose the destinations, the type of tourist destination chosen, the average length of stay and activities they prefer to do while traveling. It was analyzed if these preferences changed during the pandemics and among Romanian and foreign young tourists. As young tourists represent a significant segment of international tourism, it was considered that is important for the managers to know how consumers’ behaviors and preferences changed, so they can adapt to them in an effort to reach the pre-pandemic levels of activity.

Educação Física em escolas públicas e privadas na pandemia
Authors: Cardoso Nicole Marceli Nunes , Vasques Daniel Giordani
Published: October 2022

O ano de 2020 foi marcado pela pandemia do COVID-19. Como maneira de prevenir e diminuir a propagação do vírus, o distanciamento social foi empregado e as escolas foram forçadas a fecharem e optarem pelo ensino remoto. O objetivo deste estudo consiste em analisar as diferentes realidades do trabalho docente da Educação Física escolar nas escolas públicas e privadas de Porto Alegre-RS durante a pandemia. Um questionário online foi aplicado com 41 professores do Ensino Fundamental. Nas instituições privadas, as aulas ocorreram em sua maioria em formatos síncronas, com videoaulas e práticas, ressaltando a melhoria de saúde. As instituições públicas demoraram mais para retomar as aulas e optaram por formatos assíncronos e envio de tarefas em formatos e conteúdos diversos. Isso se deu, sobretudo, pela carência de condições para ter acesso a equipamentos tecnológicos e à internet. A liberdade de ação dos sujeitos mostra que as ações docentes são resultantes das suas concepções de mundo, mas também limitadas pela configuração.
Reading the Signs”: Aspects of Perception of a Game Polycode Text in Space of a Modern City
Authors: Gridina T. A. , Konovalova N. I.
Published: October 2022

One of the new linguocreative practices of organizing the city space as a cultural text is analyzed. The game discourse of polycode texts is considered, which combine elements of different semiotic systems: signs of traffic rules, supplemented by visualized symbolic allusions and quotations, collectively referring to the motifs of famous works of art. The constructive principles of modeling the associative context of polycode posters placed in the Literary Quarter of Yekaterinburg are characterized. The universality of the generation of game texts of any semiotic nature on the basis of an operational technique that creates the effects of associative deducibility and associative integration is substantiated. The novelty of the study is related to the description of the algorithm for creating and deciphering a game polycode text of this type, identifying the factors and strategies for reading it by the addressee. The dynamic component of the semantic diversity of the analyzed texts is experimentally verified, taking into account the respondents’ recognition of the prototypes of the game transform, reflection on the connection between its visual and verbal components, and the ability to derive allusive implicatures. Particular attention is paid to the analysis of game transform decoding strategies in the light of the mechanisms of linguocreative thinking based on the switching of associative stereotypes in the language game register.

Published: October 2022

The article deals with the formation and specifics of the development of new media in the Lipetsk region. Attention is focused on the problems of globalization and modification of regional mass media at the present stage. The results of a comparative analysis of traditional and new media in terms of convergence are presented. The question is raised about the multimediaization of journalism, the transition of traditional publications to an online format and the transformation of the types of information consumption by the audience. Particular attention is paid to the changes taking place in the local media of the Lipetsk region as a result of media convergence. The novelty of the study is expressed in a comprehensive analysis of trends and determination of the prospects for the development of regional media. The relevance of the study is due to the active expansion of the processes of media convergence, multimedia journalism, the transition of traditional publications to Internet platforms. It is proved that the development of communication technologies has led to the modification of the media, globalization and convergence factors determine the formation of a modern media system. The information and communication aspect of globalization is most manifested in the processes of interconnection and interdependence of objects and phenomena, the development of ICT, the integration of mass media, the increase in the number of global media and the growing role of the Internet.
Intertextual Subtexts of Joseph Brodsky’s Elegy “You Will Return to Your Homeland. Well...”
Authors: Bogdanova O. V. , Vlasova E. A.
Published: October 2022

The article offers an interpretation of Joseph Brodsky’s poem, rarely used for analysis, “You will return to your homeland. Well...” (1961). If traditionally Brodsky’s elegy in the intertextual aspect is considered as a “dialogue-repulsion” (A. Nesterov) with A. Vertinsky’s romance “Without Women”, then the work reveals other pretexts that at first glance seem alien to Brodsky’s love lyrics — these are texts of patriotic themes by S. Yesenin and M. Tsvetaeva. It is shown that Brodsky’s motive of homecoming is emphatically focused on “The Homecoming” and “The Soviet Russia” by S. Yesenin, in 1924, upon his return from America, formulated a sincere poetic confession in the extreme loneliness he experienced in his homeland (“My poetry is no longer needed here, / And, perhaps, I myself am not needed here either ...”). The prevailing idea of the dissimilarity of the poetry of Brodsky and Yesenin is questioned. The reference text of M. Tsvetaeva is the poem “The Homesickness. A long time ago...” (1934), as shown in the article, which served as an obvious prototype for “You will return to your homeland. Well...” The compositional structure of Tsvetaeva’s pretext with the dominant strategy of “affirmation through negation” determined the poetic organization of Brodsky’s elegy. It is argued that over time, the dialogic interaction of texts was accompanied by emotional and semantic recoding, the non-textual meanings in Brodsky’s poems grew.
Defensive Lines in System of Russian Settlement in Tobol-Ishim Interfluve at End of 16th — Middle of 18th Centuries
Authors: Zakh V. A.
Published: October 2022

The formation of defensive lines in the Tobol-Ishim interfluve, which marked the advance of the Russian population to the south, is considered. It is proved that the historical processes that took place in Tobolo-Ishimye, the construction of defensive lines, along with the inclusion of existing communications, should be considered as the formation of a structure for the settlement of the Russian and Tatar population in the process of colonization with the advance of the border of the Russian state to the south. The initial line of colonization was formed at the end of the 16th century from the first Russian prisons: Turin, Tyumen and Tobolsk, which laid the foundation for the development of the forest-steppe lands of Tobol-Ishim. The intermediate lines were P. I. Godunov’s “notch line”, which stretched from the Tarkhansky prison to the Kataisky prison, and the Ishim defensive line — from the Utyatsky outpost to the Omsk fortress. The last defensive line ran directly from the Zverinogolovsky tract through the fortress of St. Peter to Omsk, included fortresses, redoubts and lighthouses that protected the territories of the Trans-Urals and the south of Western Siberia from the raids of the Jungars and nomads of the Middle Kazakh horde. Defensive lines with dotted centers of territory development, along with roads and waterways, fastened the emerging initial framework of Russian settlement in Tobolo-Ishimye with the center in Tobolsk.
Foreign Policy Aspects in Attitudes of Germany Parliamentary Parties during Period of A. Merkel’s Chancellorship (2005—2021)
Authors: Petrosyan J. V.
Published: October 2022

The main directions in the foreign policy agendas of the leading parties in Germany during the period of A. Merkel’s chancellorship are considered. The relevance of the study is due to the need to study the strategic program settings of the German parliamentary parties, which will allow a better understanding of what the country’s future foreign policy may be. It is emphasized that the party system of Germany is quite stable: only three parties have joined the parliamentary parties of the first convocation — the CDU / CSU, the FDP and the SDPG — at the present stage: the “Union 90 / Greens”, “Left” and since 2017 — “Alternative for Germany”. Particular attention is paid to the study of the election and fundamental programs of the parliamentary parties of Germany, as they reflect the party’s “worldview”, views on the place and role of the country in the world, the ultimate or most important goals to which the party should move, as well as the means and methods for achieving the set goals. Based on the analysis of these documents, it is concluded that there is a certain consensus among parliamentary parties on key issues related to the country’s foreign policy. Demands for a revision of the chosen course are heard only from right and left populists, who do not have a significant impact on German foreign policy.
Consequences of Floods and Permafrost Degradation for Life Support System of Population of Alazeya River Basin (Second Half of 20th—21st Centuries)
Authors: Suleymanov A. A.
Published: October 2022

Based on the analysis of archival data, published scientific literature and author’s field materials, the consequences of the degradation of “permafrost” for the life support system that has developed in the village of Argakhtakh, Srednekolymsky ulus of the Republic of Sakha (Yakutia) are analyzed. To increase the representativeness of the overall picture, the transformations that have taken place are considered on the example of two cases: natural disasters during the period of a relatively stable state of the environment, on the one hand, and serious climate changes that have already occurred in recent decades. The causes, course and consequences of the 1977—1978 flood are considered. It was noted that it caused significant damage to agriculture, but the village itself was practically not affected. The floods that occurred in 1997, 2007—2008 and 2017—2018 had more serious consequences for the life support system of Argakhtakh. A significant role in their genesis played the degradation of permafrost, intensified due to an increase in the average annual air temperature and anthropogenic impact. As a result of floods, not only farmlands were flooded, but a new channel of the Alazeya River arose, a local fur farm was deprived of a stable land connection with the village, damage was caused to Argakhtakh’s housing stock, outbuildings and infrastructure facilities. It has been established that this has led to a radical reduction in the scale of the local population's employment in traditional sectors of economic activity, the elimination of fur farming, the deterioration of the transport accessibility of the village, and the costs of the population for the restoration of households.
Discovery and Arrangement of Nizhny Novgorod Public Widow’s House name of Blinovs and Bugrovs in Late XIX — Early XX Centuries
Authors: Tikhovodova A. V.
Published: October 2022

The article is devoted to the organization and cherishing of the Nizhny Novgorod city public name of the Blinovs and Bugrovs of the Widow’s House at the end of the 19th — beginning of the 20th century. The relevance of the study is due to the intensification of entrepreneurial activity and private initiative in the field of charity in modern Russia, the emergence of numerous charitable organizations and foundations, and the need to get acquainted with historical experience. The history of the construction and opening of the Widow’s House, active interaction in this process with the Nizhny Novgorod City Duma are traced in the article. Based on the charter and reports of the institution, its goals, objectives, management structure, sources of financial resources, forms of assistance to those in need are considered. The author shows the quantitative, class and age composition of the detainees, their marital status, types of occupations. Expenditure of funds (heating, lighting, repairs, purchase of food and equipment, salaries to employees, school), sources and forms of donations (charitable foundations, contributions from individuals, free meals, events, gifts) are covered in detail. The author comes to the conclusion that the Widow’s House in Nizhny Novgorod is a unique charitable institution of its time, the public need for which only increased. Thus, the second half of the 19th — the beginning of the 20th century was a period of private initiative in the matter of social security with significant support from local governments.
Political Metaphors and the Reputational Image of Power: Experience in Classifying Sociological Survey Data
Authors: Nikiforova L. V. , Rozanova N. N.
Published: October 2022

The questions of classification of political metaphors are considered. This classification is necessary for the analysis of the data of sociological survey, which was conducted by the team of Smolensk University in 2022 in regions of Russia. The study of the reputational image of power (respondents' answers to the questions: “How would you draw the reputational image of Russian / regional power?”) problematizes the principles of classification. The relevance of the study in working out the diagnosis of the reputational image of power. The novelty of the study is that the analysis was conducted on the basis of folk metaphorization, rather than professional political discourse, which researchers of political metaphorology and political semantics usually deal with. The empirical material for the problematization of the classification was the results of the sociological survey 2021, which included similar questions. The classification of power metaphors on the basis of major philosophical categories and structural relationships (space/time; living/artificial; human/nature/society) is presented, as such principle allows capturing the real diversity and multidimensionality of figurative likenesses proposed by respondents. The results of the study of folk metaphorization adjust the existing classifications of power metaphors, do not fully coincide with the known classifications of metaphorical models of power, also adjust the ideas about the popularity of typical metaphorical models.

Authors: Liu Xiaoyao , Liang Zhongcheng , Hao Weiqian , Zhao Rui , Kong Meimei , Chen Tao , Zhang Yue
Published: October 2022

Based on the characteristics of liquid lens sparse aperture imaging, a radiative multiplet array structure is proposed; a simplified model of sparse aperture imaging is given, and the analytical expression of the modulation transfer function is derived from the optical pupil function of the multiplet array structure; the specific distribution form of this multiplet array structure is given, and the structure parameters are approximated by the dimensionless method; the two types of radiative multiplet array structures are discussed, and the filling factor, redundancy, modulation transfer function and other characteristic parameters are calculated. The physical phenomena exhibited by the parametric scan are discussed, and the structural features and imaging characteristics of these two arrays are compared. The results show that the type-II structure with larger actual equivalent aperture and actual cutoff frequency and lower redundancy is selected when the average modulation transfer function and the IF characteristics of the modulation transfer function of the two structures are close to each other; the type-II structure has certain advantages in imaging; the conclusion is suitable for arbitrary enclosing circle size because the liquid lens-based multiplet array structure adopts dimensionless approximation parameters; compared with the composite toroidal structure, the radiative multiplet mirror structure has a larger actual cut-off frequency and actual equivalent aperture when the filling factor is the same.
Cardiac amyloidosis imaging
Authors: De Arenaza Diego Pérez , Baratta Sergio , Campisi Roxana , Cerda Miguel , Aguirre Adela , Villanueva Eugenia , Fernández Alberto , Belziti César
Published: October 2022

Amyloidosis is a systemic disorder produced by the deposition of insoluble protein fibrils that fold and deposit in the myocardium. Patients with amyloidosis and cardiac involvement have higher mortality than patients without cardiac involvement. The two most prevalent forms of amyloidosis associated with cardiac involvement are AL amyloidosis, due to the deposition of immunoglobulin light chains, and ATTR amyloidosis, due to the deposition of the transthyretin (TTR) protein in mutated or senile form. This article aims to review the different cardiac imaging modalities (echocardiography, cardiac magnetic resonance imaging, nuclear medicine and tomography) that allow to determine the severity of cardiac involvement in patients with amyloidosis, the type of amyloidosis and its prognosis. Finally, we suggest a diagnostic algorithm to determine cardiac involvement in amyloidosis adapted to locally available diagnostic tools, with a practical and clinical approach.

Authors: Muñoz Andrade Luis Adrián , Almanza Rosana Fabregas , Chuizaca Jeyson Eddy Roth , Criollo Andrea Geovanna Sanipatín
Published: October 2022

Focused Assessment with Sonography for Trauma (FAST) has been widely used and studied in blunt and penetrating trauma for the past 3 decades. Prior to FAST, invasive procedures such as diagnostic peritoneal lavage and exploratory laparotomy were commonly used to diagnose intra-abdominal injuries. Today, the FAST examination has evolved into a more comprehensive study of the abdomen, heart, thorax, inferior vena cava, among others, with many variations in technique, protocols and interpretation. Trauma management strategies such as laparotomy, endoscopy, computed tomography angiography, angiographic intervention, serial imaging and clinical observation have also changed over the years. This technique, at times, has managed to replace computed tomography and peritoneal lavage diagnosis, without producing delays in the surgical procedure. As such, the relationship between the patient’s clinical information and the results of the exam should be guided to guide therapeutic approaches in difficult to access settings such as intensive care units in war zones, rural or remote locations where other imaging methods are not available. This review will discuss the evolution of the FAST exam to its current status and evaluate its evolving role in the acute management of the trauma patient.

Authors: Villanueva Bendek Ignacio , Ruiz Mauricio , Vega Lia
Published: October 2022

Vascular access in hemodialysis is one of the pillars of success of the program. Therefore, efforts should be directed firstly to achieve the greatest number of vascular accesses of the arteriovenous fistula type, and secondly to reduce complications related to access cannulation in order to functionally preserve the access. Several strategies have been described to improve this last aspect; this article describes the use of ultrasound to improve the probability of successful cannulation in cases considered difficult by the nursing team.

Published: October 2022

The detection of urban expansion through digital processing of satellite images provides valuable information for understanding the dynamics of land use change and its spatial relationship with environmental factors. In order to apply or generate effective land-use planning policies, it is essential to have a historical record of the regional distribution of human settlements, an element that is practically non-existent in our country. For this reason, this text aims to determine the urban growth rate during the period 2000–2014 in the state of Hidalgo, Mexico, and to identify potential expansion zones from Landsat images. Six Landsat scenes were used for the spatial analysis of the state urban coverage and their relationship with the road influence area was evaluated. Two maps were obtained as cartographic products: one of urban coverage distribution and another of the municipalities with the greatest expansion, whose areas are located in the Valle del Mezquital region. However, Mineral de la Reforma, Tetepango, Tizayuca and Pachuca de Soto stand out for their growth rates during the study period: 183.44%, 102%, 94% and 68.5%, respectively. In total, the state urban area in-creased 72.3 km2 from 2000 to 2014 with an average growth rate of 1.8% per year. Such growth was associated with the areas of influence of important road infrastructure, such as the Libramiento Arco Norte in Hidalgo. Therefore, the Mezquital Valley and the Mexico Basin are considered as potential regions for urban expansion in the state.

Authors: Ammann Liliane , Ohlerth Stefanie , Fürst Anton E. , Jackson Michelle A.
Published: October 2022

OBJECTIVE

To determine morphological characteristics of subchondral cystic lesions (SCLs) in the proximal phalanx (PP) of adult horses.

SAMPLE

Radiographs and/or CT scans of PP from 46 horses.

PROCEDURES

There were horses with a SCL in PP, which was diagnosed by radiography and/or computed tomography, included. Additional data (signalment, history, orthopedic examination) were collected retrospectively for each case.

RESULTS

Forty-six horses met the required inclusion criteria, with a total of 62 SCLs. Forty-three SCLs (70.5%) were located in the proximal PP (group A). Forty-four percent of these were associated with short, incomplete fractures, while 30 of the proximal PP SCLs (69.7%) were found mid sagittal. Proximal SCLs mostly showed a blurred, irregular shape (62.8%) and long, as well as wide, but shallow shapes in CT. Eighteen SCLs (29.5%) were found in the distal PP, near the proximal interphalangeal joint (group B). In contrast to the described proximal SCLs, the distal SCLs were of circular or oval shape, well delineated (77.8%), and distinctly larger. Horses of group A were significantly older (mean age, 11.47 years) than horses of group B (mean age, 6.72 years).

CLINICAL RELEVANCE

The distribution and morphological attributes of proximal PP SCLs as well as their association to subchondral bone lesions and short, incomplete proximal fractures indicate more recently developed lesions due to chronic stress factors, such as repetitive trauma to the cartilage and subchondral bone. In contrast, morphology and distribution of distal SCLs showed high accordance with developmental bone cysts originating from a failure of endochondral ossification.

OBJECTIVE

To determine the 50% effective dose (ED50) of intravenous propofol required for successfully preventing tracheal intubation response in Beagles co-induced with dexmedetomidine.

ANIMALS

36 adult male Beagles

PROCEDURES

The dogs were randomly assigned to either group D1, group D2, or group C (received 1 µg/kg, 2 µg/kg dexmedetomidine intravenously, or the same amount of normal saline as dexmedetomidine, 10 mL). The first dog in each group received 6 mg/kg of propofol for induction. The pump speed of propofol was 600 mL/h. The dosage varied with increments or decrements of 0.5 mg/kg based on the Dixon up-and-down method. The duration of eye-opening after propofol administration was recorded. Changes in heart rate (HR) and respiratory rate (RR) were recorded at 5 timepoints: after entering the operation room and prior to propofol administration (T1), 1 and 3 min after propofol administration (T2 and T3), 3 and 5 min after intubation (T4 and T5).

RESULTS

The required ED50 of propofol that prevented tracheal intubation response in D1, D2, and C groups were 6.4 mg/kg (95% CI, 6.1 to 6.7 mg/kg), 5.8 mg/kg (95% CI, 5.67 to 6 mg/kg), and 8.3 mg/kg (95% CI, 8 to 8.5 mg/kg), respectively. The recovery time of group D2 was significantly longer than that of groups D1 and C (P < .05). The differences in HR among the 3 groups were significant from T2 up to T5 timepoint (P < .05). The differences in RR among the 3 groups were significant at T2 and T3 timepoints (P < .05).

CLINICAL RELEVANCE

Dexmedetomidine pre-injection reduces the amount of propofol required for endotracheal intubation response in Beagles, thereby reducing the respiratory inhibition induced by propofol.
ScriptNet: An integrated criminological-network analysis tool
Authors: Bellotti Elisa , Lord Nicholas , Elizondo Cecilia Flores , Melville Joshua R. , Mckellar Steve
Published: October 2022

This brief article illustrates the features of ScriptNet, a software package that facilitates a visual analysis of the organisational aspects of criminal enterprise, together with a visual analysis of the network of people, organisations, places and resources that are in some way involved in the commissioning of these goal-oriented crimes. ScriptNet is an amalgamation of the terms ‘script’ and ‘network’ that in turn represent two analytical approaches to understanding criminal and social behaviours. Script refers to crime script analysis, an analytical technique that organises knowledge about the procedural aspects and procedural requirements of the crime commission process. Network derives from social network analysis, and specifically from the framework of multi-mode and multi-link networks, which maps individual and collective actors, together with resources they can access and places where they are located, and the various types of relationships that may link them. In this article we illustrate the functions and features of ScriptNet using data provided by the Food Safety Authority of Ireland (FSAI). We discuss the innovative aspects of ScriptNet and we identify its limits. In its current format, ScriptNet has been developed as proof of concept. The code is open source, and we welcome people to collaborate and implement new and improved functions.
Comparative Analysis of Combustion of Qualified Composite Fuel for the Transitional Period in the Household and Communal Sector in Poland

Published: October 2022

The article presents the results of laboratory combustion tests of the microbriquette obtained from useless coal (grain class of < 5 mm) generated in the production of “eco-pea” (eko-groszek) coal. The briquettes of 1.5 and 2.5 cm3 were made in a roller press of crushed coal granulation down to 2 mm, mixed with a binder and/or catalytic additives and sorbents, then dried to final moisture of about 7%. The tests were carried out on a specially designed stand enabling to determine the differential curve of the weight loss of samples heated to the ignition temperature and then burnt with laminar airflow by natural chimney draft. Comparative tests were carried out with ecopea coal from the “ZG Sobieski” mine. The results indicate that composite fuels, in the form of microbriquette, ignite faster, burn at a higher temperature and leave less ash when burned than lump coal. The greater reactivity of the briquette concerning the lump coal allows for minimizing the air rate by about 10%, which also reduces the exhaust gas volume by the same amount and the stack losses. It reduces the velocity of dust lifting, which leads to the reduction of their emission.
Future Sustainable Maritime Sector: Energy Efficiency Improvement and Environmental Impact Reduction for Fishing Carriers Older than 20 Years in the Fleet Part II

Published: October 2022

For the maritime sector to be sustainable and to have an intact blue economy, shipowners should be ready to implement Ship Energy Efficiency Management Plans alongside energy efficiency projects. The problem for organizations and shipowners having fishing carriers older than 20 years is highlighted and the following challenges arise for decision-making authorities. To keep such ships in the fleet for the next decade, shipowners should deploy energy efficiency projects for marine system retrofitting to improve energy efficiency and meet environmental regulations. An energy audit is performed and an energy efficiency program is proposed with guidelines for regulations that are currently coming into force. To improve energy efficiency, reduce the environmental impact, and cut fuel consumption costs, marine system retrofitting is done, in a particular case, with two options proposed. The first is a cascade refrigeration system with hydrocarbons and carbon dioxide, where the shipowner gains an energy efficiency improvement of about 20%. The second option is a two-stage refrigeration system with ammonium as the environmentally friendly refrigerant, which improves the energy efficiency by about 26%. Technical and economic issues have been discussed.
CHEMICAL WEAPON USAGE RELATED TO SELF-DEFENSE ARRANGEMENT IN ARTICLE 51 OF THE UNITED NATIONS CHARTER
Authors: Faradilla Rizka , Adwani Adwani
Published: October 2022

Abstract- This paper aims to find out the regulation and the use of chemical weapons as a state’s self-defense and to explain why some countries use chemical weapons to defend themselves from attacks by other countries. This study was conducted based on normative legal method. It was found that Article 51 of the United Nations Charter, which regulates self-defense, does not specifically explain the use of permissible weapons in self-defense, so in practice, there are still many countries that use chemical weapons despite their use being forbidden in war (humanitarian law). The United Nations should amend to the contents of the United Nations Charter, especially in Article 51 on Self-defense, in order to add more detailed rules regarding anticipatory actions for self-defense so that no country admits to carrying out armed attacks with the aim of self-defense for their respective interests and harming many parties.
Виртуальный музей археологии: архитектоника музейного пространства

Published: October 2022

Статья посвящена исследованию виртуального музея как формы цифровой музеефикации археологического наследия. На основе изучения российского опыта создания археологических информационных ресурсов в сети Интернет показаны новые возможности сохранения и актуализации археологического наследия с помощью его цифровой музеефикации. Рассматриваются сложившиеся к настоящему времени подходы определению понятия «виртуальный музей», поставлен вопрос о критериях отнесения того или иного информационного ресурса к виртуальному музею. В структуре культурного пространства виртуального музея выделены ценностно-смысловое, социальное пространство и медиапространство. На основе критерия доминирования тех или иных свойств гипертекста – фрагментарности или интегративности – выделены наиболее популярные сегодня модели обустройства (архитектоники) пространства виртуального музея: виртуальная коллекция и виртуальный тур. Отмечается, что пространство виртуальных музеев отражает изменения, происходящие в музейном пространстве в целом, и в тоже время ярко их проявляет благодаря своим возможностям. Виртуальные музеи приобретают самостоятельное значение.
