Эти законы могут применяться для прогнозов поведения сложных негэнтропийных систем. Таких – например – как экологические и биологические системы. Примерами подобных систем служат центральные нервные системы и нейросети, экосистемы и колонии муравьев, социальные структуры и политические системы, и, конечно, различные структуры, возникающие в экономике и медицине катастроф. Все эти системы состоят из множества взаимодействующих элементов, которые способны накапливать опыт в процессе взаимодействия с другими элементами, а затем изменяться таким образом, чтобы приспособиться к окружающей среде. Характерным этапом эволюции всех адаптивных систем является процесс самоорганизации, при котором в результате самоусиления отдельных взаимодействий в системе спонтанно возникает порядок. При этом сама система как целое приобретает новое качество, которое может отсутствовать у отдельных элементов. Такими системами – например – являются макроскопические каскады запутанных квантовых состояний, которые могут быть детерминированы до одного из собственных значений по параметрам кинетики какого либо – макроскопического опять же по сути – биологического процесса. То есть перейти из суперпозиции состояний в иное детерминированное декогеренцией качество. И «самоорганизовываться» из квантовых в классические объекты тогда, когда некоторое количество квантовой информации запутанных состояний микрочастиц – во фрактальных подмножествах множества каскадов чистых состояний какого либо биологического процесса, телепортируемого в виде электромагнитных волн – способно изменить ход целого ряда биологических макроскопических процессов. Либо инициировать классическое возникновение новой последовательности процессов – через мезоскопическое пространство электродинамических событий.
Exploring climate change, ecosystems and well-being connections: lessons learned from the application of a geospatial knowledge exchange tool in the Nechako watershed
Authors:   , Gothreau Joseph
Published: November 2021

The Nechako Watershed is a large system in northern BC that exemplifies the challenge of integrating information across climate, environment and well-being. This research responded to this need with the goal of enhancing how information about the Nechako Watershed is communicated and shared. Informed by the development of a geospatial ‘portal’ tool in northern BC, this research sought to establish the Integrated Watershed Research Group (IWRG) Portal, gain insight on establishing accessible knowledge exchange strategies, and identify its perceived benefits and limitations. The research had two phases. Phase I involved working with a development team to understand this tool, testing, establishing the IWRG Portal, finding and formatting content. Phase II brought members of the Portal User Research Group together to further refine the IWRG Portal and content through scoping discussions, workshops, and a focus group. Thematic analysis was used to code and analyze the transcribed focus group. The research identified benefits of the portal with how it dealt with complexity and its integrative features. Limitations were also found, including the need for intentional framing of data, a steep learning curve, and the need for an internet connection. Analysis also identified the need to tailor content for specific audiences. The research has shown that tools such as the IWRG Portal can create new pathways to understanding and finding information. The research has also identified paths for further refinement and development of the portal tool by expanding the user base and continuing to evaluate the effectiveness of this tool in various contexts.

Authors: Sankaran M , Kalaivanan D , Gowda Suni
Published: November 2021

Mutation breeding is a key method of generating a large number of heritable variations. Effective dose (LD50) needs to be standardized for inducing sufficient variation in a crop. In the present study, seeds were irradiated with different doses of Gamma rays and found that 66.94 Gy could suppress germination close to 50 percent (LD50) in pummelo. This 60 Gy gamma dose can effectively be used for raising the mutant populations to identify a desirable mutation in pummelo.

Authors: LOLEA Marius Savu , MINDA Andrea Amalia , SZABO Emeric Remus , NEGREA Daniela Tabita
Published: November 2021

In order to make the decision to implement a project from any do-main, several aspects must be analyzed in the preliminary stage, leading to the justification of the practical realization of the project. Feasibility is based on technical-economic criteria but also involves other impact factors, such as social and ecological. In the case of hydrogen, there are not many countries with experience in the field, but in the future it is expected that hydrogen technologies will expand, from production, transport, storage, distribution and use. There are more and more factors that encourage the development of hydrogen projects and the funding proposed through European environmental agreements is a real challenge for specialists. Therefore, the authors of the paper aimed to analyze several aspects of the feasibility of hydrogen production and storage projects with the identification of implementation conditions: benefits, efficiency, costs, sources of funding, entities involved, constraints or legislative framework.
The 2000 Romanian Presidential Elections – between Populism and Europeanism
Authors: MUREȘAN Marius
Published: November 2021

In November 2000, ten years after the fall of the communist regime and the organization of the first free elections, the Romanian population was called to decide on the future president of the country. This was the first poll that took place after the transition between power and opposition, which took place in 1996, but also in the context of a serious economic crisis with considerable effects on living conditions, which marked the activity and political destiny of PNŢCD. The elections, especially the second round, proved to be representative not so much from the perspective of political options, but especially regarding the future of the country: open to Euro-Atlantic structures or isolated, oriented towards the former Soviet space. These visions were personalized by the two candidates, Ion Iliescu and Corneliu Vadim Tudor, and the present article analyses the electoral mechanisms the two tried to use in order to promote their platforms within a Romanian society marked by the economic recession, but also by a major moral and identity crisis.
Rezumat: În noiembrie 2000, la zece ani distanţă de la căderea regimului comunist şi de la organizarea primelor alegeri libere, populaţia din România a fost chemată să decidă cu privire la viitorul preşedinte al ţării. Acesta a fost primul scrutin care a avut loc după tranziţia între putere şi opoziţie, care s-a petrecut în 1996, dar şi în contextul unei grave crize economice cu efecte considerabile asupra condiţiilor de viaţă, care a marcat activitatea şi destinul politic al PNŢCD. Alegerile, mai ales al doilea tur de scrutin, s-au dovedit a fi reprezentative nu atât din perspectiva opţiunilor politice, dar mai ales în ceea ce priveşte viitorul ţării: deschis pentru structurile euro-atlantice sau izolat, orientat înspre spaţiul ex-sovietic. Aceste viziuni au fost personalizate de cei doi candidaţi, Ion Iliescu şi Corneliu Vadim Tudor, iar articolul de faţă analizează mecanismele electorale prin care cei doi au încercat să îşi promoveze platformele în cadrul unei societăţi româneşti marcate de recesiunea economică, dar şi de o importantă criză morală şi identitară.

Assessing the Social-ecological Resilience of Organic Farmers in Chiang Mai Province, Thailand
Authors: Panpakdee Chaiteera , Limnirankul Budsara , Kramol Prathanthip
Published: November 2021

Since resilience is continuing to make its rise to the top of the sustainable development policies, monitoring resilience has become critical because it provides stakeholders with practical actions that can strengthen the state of adaptability to cope with all kinds of change. In this study, resilience, and social theories, such as grounded theory and technography, were integrated as a conceptual framework to produce a specific set of indicators, which yielded forty-seven indices, called social-ecological resilience indicators (SERIs). This study attempts to manage the temporal and spatial scales of resilience systems and to make such indicators suitable for organic rice production systems in four districts of Chiang Mai Province. A questionnaire was utilized to survey fifty-three organic farmers, and the results of the descriptive data analysis indicated that 0.54 (1.00 = the maximum) had been the respondents’ average score. Meanwhile, the highest and the lowest scores were serially 0.69 and 0.40. In addition, the findings revealed that Kendall’s Tau-b rank correlation’s numeric value came closer to +, which meant that the respondents had demonstrated an average tendency to be resilient. Generally, the highest score of resilience existed for those organic farmers, who had been outstanding in creating opportunities for self-organization, such as considerably relying on food and farm materials from the availability of local resources. Moreover, the majority of them were found to have a secondary on-farm profession that was not only subsidizing additional incomes but was also providing new knowledge and opportunities. This contrasted with the group with lowest score. The farmers, who exhibited unsatisfactory resilience, were centralized in dimensions, ranging from a having a lack of diverse water sources to having sufficient competency to exploit the benefits of Information and Communication Technology (ICT). They are, therefore, more prone to being affected by negative pressures. It is recommended that for building resilience, the ‘holy grail’ is boosting self-reliance. This capacity is key to reducing the risk of losing sustenance and enabling stakeholders to apply the appropriate strategies in times of change

Published: November 2021

In recent years, there has been an increased use of information and communication technologies and mathematical software in mathematics teaching. Numerous studies of the effectiveness of mathematical learning have shown the justification and usefulness of the implementation of new teaching aids. They also showed that learning with educational software has a great impact on students' achievement in the overall acquisition of mathematical knowledge during the school year as well as in the final exam at the end of primary education. Teaching realized by using computers and software packages is interesting for students, increases their interest and active participation. It is indisputable that the use of computers and mathematical software has great benefits that have been proven and presented in their works by many researchers of effective learning. It is also indisputable that one of the main tasks of teaching mathematics is to develop constructive thinking of students. Visualization and representation of mathematical laws are of great importance in the realization of mathematics teaching. They should be applied everywhere and whenever possible.
Adad [Antonyms] and Its Impact on the Exegesis of Al-Samin in His Books (Al-Durr) And (Al-’Umda)
Authors: Rayan Dr. Ayman Ibrahim Yusuf
Published: November 2021

This research tackles the subject of the indication of antonyms and its impact on the exegesis of al-Samin in both his books “al-Durr al-Masun” (Preserved Pearls) and “‘Umdat al-Hufaz” (Reliance of the memorize-rs). In this research, I have combined between the language and tafsir (exegesis) and clarified the efforts exerted by al-Samin in serving the interpretation of the Quran. Moreover, I have introduced his great contribution to linguistic research and compiled the conclusions he has reached in both his books (al-Durr) and (al-’Umda) on antonyms. I have organized his ideas, studied his tangible effects in his exegesis of the holy Quran in addition to methodologically establishing the role of the language being one of the tools in the past and contemporary exegesis of the holy  Quran and clarified its multiple indications and various manners. I was also keen in highlighting the importance of the indication of antonyms and the extent of its impact on interpreting the noble Quran. Moreover, I have studied the points of contention among the scholars and exegists on the meaning of the Quranic statement and clarified the importance of the Quranic context in determining the exact meaning of the vocabularies and structures. Furthermore, I have highlighted the close connection between the developed indication of words and the intended meaning in the Quranic verse.

Authors: Yippaditr Wanchart , Watanangura Antja , Pencharee Disdanai , Sasaki Nobuo
Published: November 2021

OBJECTIVE

To evaluate the feasibility of buccal mucosal graft urethroplasty for repairing complete urethral rupture in cats.

ANIMALS

15 male domestic shorthair cats with traumatic complete urethral rupture.

PROCEDURES

In each cat, a section of buccal mucosa was harvested, sutured, and formed into a tubule by use of an 8F indwelling catheter as support. This tubular graft was connected to both ruptured ends of the urethra to renew the urinary passage. The catheter was left in place until the absence of leakage was confirmed by positive contrast retrograde urethrography. After spontaneous urination was confirmed, cats were discharged from the hospital. Six months later, urethrography was repeated and owners were asked to score their cats’ urinary function and quality of life.

RESULTS

13 cats recovered well following surgery, with no complications in the oral cavity or surgical site and no signs of difficulty or discomfort when urinating. Urethrography 2 weeks and 6 months after surgery revealed no stricture or leakage in the abdominal cavity. The 2 remaining cats developed a urethral stricture and underwent second surgery with a successful outcome. At the 6-month follow-up, 14 cats had only mild urinary signs, and 1 cat had incontinency. Owners indicated they were delighted (n = 14) or pleased (1) with their cats’ quality of life.

CLINICAL RELEVANCE

Buccal mucosa was found to be a good source of graft tissue for performance of urethroplasty in male cats, yielding satisfactory outcomes with few postoperative complications. The described technique may be suitable for severe and complicated cases of urethral rupture in male cats.
Jejunal strangulation and incarceration associated with bilateral perineal hernias in a neutered male dog
Authors: Iodence Ashley E. , Perlini Michael , Grimes Janet A.
Published: November 2021

CASE DESCRIPTION

An 8-year-old 6.8-kg neutered male Dachshund was presented for evaluation of vomiting, diarrhea, anorexia, and swelling over the right perineal region. The dog had a history of a bilateral perineal herniorrhaphy and castration 14 months prior to presentation.

CLINICAL FINDINGS

Bilateral perineal hernias were confirmed by digital rectal examination. Abdominal ultrasonography confirmed the presence of intestine within the right hernia. Three days after admission to the hospital, the region of the right perineal hernia became painful, erythematous, and edematous. Computed tomography revealed jejunal incarceration within the right hernia with dilation of 1 jejunal segment that indicated intestinal obstruction.

TREATMENT AND OUTCOME

Abdominal exploratory surgery was performed, during which irreducible small intestinal incarceration was confirmed. Intra-abdominal jejunal resection and anastomosis was performed, and an approximately 13-cm-long section of the jejunum was resected. Bilateral perineal herniorrhaphies with internal obturator and superficial gluteal muscle transposition were performed. Six months after surgery, digital rectal examination of the dog revealed that the repair was intact. The dog had no perineal hernia–related clinical signs at the time of the recheck examination.

CLINICAL RELEVANCE

For the dog of the present report, surgical management of small intestinal strangulation associated with a perineal hernia was successful. Although a portion of the small intestines can frequently be found within perineal hernias in dogs, perineal hernia-related small intestinal strangulation has not been previously described, to the authors’ knowledge. Veterinarians and clients should be aware of this potential complication secondary to perineal hernia and be prepared to perform an abdominal surgical procedure to address small intestinal incarceration in affected dogs.

Authors: Seal Lauren M. , Mullaney Sara B. , Waugh Sheldon G.
Published: November 2021

OBJECTIVE

To describe the presence of Leishmania infection within the animal population receiving care from US Army Veterinary Services.

ANIMALS

629 canine, feline, and equine patients of US Army Veterinary Services from 2014 to 2017.

PROCEDURES

Personnel at the US Army Public Health Center ran a query within the Remote Online Veterinary Record system using previously validated search terms (eg, liesh, leish, and lesh) and returned data on any patient for which the master problem list included those terms. Next, a query was run to identify all leishmaniasis testing. Records identified by queries were reviewed manually, and data were collected on patient signalment, indication for and type of testing, location of testing, and previous locations or country of the patient.

RESULTS

Only dogs (n = 378), not cats or horses, had been tested for leishmaniasis, 54 (14.3%) of which tested positive for Leishmania infection. More specifically, 39 of 104 (37.5%) privately owned dogs tested positive, compared with 15 of 274 (5.6%) government-owned dogs. Overall, 186 dogs had no clinical signs, 12 (6.5%) of which tested positive. Forty-four of the 54 (81%) test-positive dogs were located in or had traveled to an endemic area.

CLINICAL RELEVANCE

The prevalence of leishmaniasis in the various subpopulations of dogs suggested the need for additional prevalence studies. Many animals travel in and out of the US, and repeated introduction of Leishmania spp could lead to this vector-borne disease becoming endemic in the US animal and human populations. Consequently, US veterinarians need to ensure proper testing and follow-up to protect one health.

Many countries have established implementation strategies for the use of BIM in construction projects which have resulted in the widespread adoption of BIM. To catch up, the Ministry of PUPR has launched the Indonesia Digital Construction Roadmap 2017-2024 through 4 stages, namely the Adoption, Digitalization, Collaboration, and Integration stages. However, currently at the Adoption stage of the Roadmap, it is still focused on only a few PUPR infrastructure projects. This is due to problems such as the unavailability of policies and regulations for implementing BIM for the entire PUPR infrastructure sector, the lack of mastery of BIM from both Users and Service Providers, the project scale is not yet massive so that the price of BIM software is felt to be still burdening the Provider. This study aims to investigate the mastery of BIM through a study of the level of use, implementation, and identification of the dominant barriers to BIM adoption, especially for construction project actors in Bali. This research is expected to help construction industry practitioners to understand the challenges of BIM adoption in Bali. Data collection was carried out by survey method using a questionnaire. Respondents were selected using the purposive sampling method, namely experts in construction projects in Bali. The method of analysis is descriptive statistics which includes central tendency measurement, variability measurement, and the Relative Importance Index (RII). The survey results from all respondents showed that the adoption rate of BIM for construction project actors in Bali was 19%. Level of BIM implementation of construction project actors in Bali were 89% at BIM level 1 and 11% were at BIM level 2. The dominant obstacles in BIM adoption are the high cost of adoption, lack of experts, lack of government role in encouraging BIM adoption, difficulty changing work processes and there is no standard and protocol in applying BIM in the project.

Sampai saat ini masih banyak permasalahan yang dialami dalam pengelolaan jaringan irigasi akibat kurang optimalnya peran serta pemangku kepentingan, lambatnya respon penanganan terhadap masalah pengelolaan jaringan irigasi sehingga berdampak pada tidak meratanya pembagian air dari saluran tersier ke areal pertanian. Hal ini juga terjadi pada Daerah Irigasi (DI) Tiyingtali yang mengalami permasalahan jaringan irigasi seperti terjadinya sedimentasi pada saluran sekunder yang mengakibatkan besarnya volume pelimpahan air saat musim hujan, serta kurang optimalnya pembagian air dari hulu ke hilir. Sehingga penelitian ini bertujuan untuk menganalisis peran serta pemangku kepentingan dalam pengelolaan jaringan irigasi pada DI Tiyingtali. Pendekatan yang digunakan dalam penelitan adalah dengan pendekatan eksploratif dan metode deskritif analitis. Pengumpulan data dilakukan menggunakan kuisioner dan wawancara. Teknik pengambilan sampel/responden pada penelitian ini menggunakan metode purposive sampling, yaitu responden yang menangani pengelolaan jaringan irigasi di DI Tiyingtali yang mecakup pemerintah 25 responden dan pengelola subak 33 responden. Analisis data dilakukan menggunakan regresi linear untuk menganalisis pengaruh peran serta pemangku kepentingan terhadap pengelolaan jaringan irigasi. Selanjutnya dilakukan analisis deskriptif dari hasil wawancara untuk merumuskan upaya peningkatan kinerja dan peran serta pemangku kepentingan. Hasil penelitian menunjukkan pemangku kepentingan berperan sebesar 68,3% dalam pengelolaan jaringan irigasi, sedangkan 31,7% sisanya dipengaruhi oleh faktor lainnya. Pemangku kepentingan secara bersama-sama berpengaruh signifikan secara simultan dan secara parsial terhadap pengelolaan jaringan irigasi artinya peningkatan peran serta pemangku kepentingan secara simultan maupun parsial akan meningkatkan kegiatan pengelolaan jaringan irigasi.

Object and purpose of research. The object under study is a sandwich plate with two rigid anisotropic layers and a filler of soft isotropic viscoelastic polymer. Each rigid layer is an anisotropic structure formed by a finite number of orthotropic viscoelastic composite plies of arbitrary orientation. The purpose is to develop a mathematical model of sandwich plate. Materials and methods. The mathematical model of sandwich plate decaying oscillations is based on Hamilton variational principle, Bolotin’s theory of multilayer structures, improved theory of the first order plates (Reissner-Mindlin theory), complex modulus model and principle of elastic-viscoelastic correspondence in the linear theory of viscoelasticity. In description of physical relations for rigid layers the effects of oscillation frequencies and ambient temperature are considered as negligible, while for the soft viscoelastic polymer layer the temperaturefrequency relation of elastic-dissipative characteristics are taken into account based on experimentally obtained generalized curves. Main results. Minimization of the Hamilton functional makes it possible to reduce the problem of decaying oscillations of anisotropic sandwich plate to the algebraic problem of complex eigenvalues. As a specific case of the general problem, the equations of decaying longitudinal and transversal oscillations are obtained for the globally orthotropic sandwich rod by neglecting deformations of middle surfaces of rigid layers in one of the sandwich plate rigid layer axes directions. Conclusions. The paper will be followed by description of a numerical method used to solve the problem of decaying oscillations of anisotropic sandwich plate, estimations of its convergence and reliability are given, as well as the results of numerical experiments are presented.

Object and purpose of research. This research was intended to validate supercomputer-based optimization procedure for propulsion systems of carrier ships, with a case study of hull shape and propeller optimization for a Project 1594 vessel. Materials and methods. The optimization proceeds in Russian software package pSeven. The computation core is Siemens Star CCM+ software. Three-dimensional parametric model of the propeller is generated in KSRC-developed BladePlus software, whereas three-dimensional parametric model of the hull is generated in Siemens NX software package. Hydrodynamic parameters of the propulsion system are obtained as per CFD methods. Viscous flow parameters are obtained through control volume-based solution of unsteady Reynolds equations (URANS) closed by biparametric semi-empirical turbulence model. Main results. The study yielded a new bow shape offering lower wave-making resistance for the same overall dimensions. It also yielded a new shape of propeller offering higher efficiency than the initial one taking into account the limitations for available shaft torque. Design hydrodynamic parameters have been confirmed by the model test data obtained at KSRC Deepwater Test Tank. Propulsion performance calculation has shown a growth in the achievable speed of the optimized propulsion system in different running conditions. Conclusion. The optimization studies intended to improve propulsion efficiency of Project 1594 ships yielded new shapes for hull and propeller. The solution thus obtained features high propeller efficiency and low wave-making resistance of the hull. Numerical simulation results have been confirmed with experimental data.
Academic and Professional Mobility and its Transformative Potential
Authors: Foutz Brittany , Polkinghorn Brian
Published: November 2021

With the development of exchange mechanisms, periods of mobility abroad have become frequent, sometimes unavoidable, in the school curriculum of a student. Taking the form of semesters of study in a foreign university or work placements for higher education students, the skills acquired during these immersion phases, both linguistically and technically, and in terms of know-how, are undeniable and valued by numerous research works. In this paper, we will review the impact of international exchanges on the professional integration of students. We are interested in the academic and professional gain linked to the international mobility that organizations, such as Regional Centre of Expertise (RCE) locations, can offer to college students. We propose, in our research, to examine the construction and contribution of the opportunities that these RCE locations can offer to students, in terms of academic, professional and social development. This study will highlight RCE Salisbury, of which is hosted by the organization the Bosserman Center of Conflict Resolution, as a case study.

Prospects for the development of national economy in the context of integration of blockchain technologies into the system of economic processes testify necessitate elaboration of the methods and algorithms for formalized assessment of their impact upon the key parameters of socioeconomic dynamics. If within scientific-and-expert space, one may occasionally come across the works dedicated to separate aspects of this scientific methodological problem, the questions of the impact of blockchain technologies upon individual economic sectors are yet to be explored within the information-analytical and scientific space. The methods of empirical research of the impact of blockchain technologies upon the parameters of economic development currently did not find their consolidated solution, and are of fragmentary nature. This research is an attempt to strengthen the positions of formalized approaches towards examination of the articulated scientific and practical problem. The subject of this research is the economic relations of economic agents pertaining to implementation of blockchain technologies in the economic activity and formation of the new business models. The object is the types of economic activity of the national economy of the Russian Federation and their sensitivity to the diffusion of blockchain technologies. The article offers an algorithm for studying the dynamics of gross value added of the economic sectors of the Russian Federation through the prism of possible transformation of the key parameters of functionality of the financial and real sectors of the economy as a result of diffusion of blockchain technologies. Leaning on the advanced hypotheses, the author builds co-integration models for the indicated types of economic activity, which reveal the contribution of exogenous factors that are being adjusted under the pressure of infiltration of the distributed data storage technologies into the economic environment to the degree of incremental value added. This allows conducting cluster analysis of the economic sectors under review in accordance of their sensitivity to institutional changes caused by integration of the blockchain technologies into the economic environment.
From totalitarian regimes towards multipolar world: advantages and disadvantages of the new senior year curriculum on history in France
Authors: Osipov Evgeny Aleksandrovich
Published: November 2021

History taught in schools becomes increasingly important worldwide. School textbooks, standards and curricula on, which used to be just part of the learning process, turn into documents that are subject to extensive discussion. Leaning in the contemporary French scientific literature and speeches of the representatives of the French Ministry of National Education in a panel sessions of the Russian-French group on modernization of school curriculum on history (2018–2019) and at the World Congress of School History Teachers held in Moscow in October 2021, analysis is conducted on the curriculum on history for senior year students, that came into force on September 1, 2019. The new school curriculum is structured in such a way that the rivalry between totalitarian regimes in the 1930s, primarily between the Soviet Union and Germany, is the key factor of the outbreak of World War II, which unfortunately corresponds to modern political trends in Western countries, but contradicts the historical facts. It arises questions and draws excessive attention to the program of the protection of the rights of minorities, and the elements of gender theory overall. At the same time, heightened attention to the history of genocides in the XX century, coverage of the events of 1968 and 1989 in global scope as separate topics, and a multifaceted approach towards teaching history of the Cold War are the strong points of the new French school curriculum on history.
