A great number of injuries when performing the work at height are recorded when falling from the stairs. Injuries due to falling from height including ladders are usually severe and even fatal. At the same time, about 70 % of injuries occur with portable ladders. Most often, the fall of a person is caused by the effect of sliding ladders and breaking the stability of its overall structure. One of the ways to increase the stability of the ladder is to use attachments on its upper part. Depending on the method of coupling with the support, the possibility of adjusting the coupling area, as well as the presence of built-in safety systems, different types of attachments are used. The article considers the forces that cause the slip and fall of the ladder when using it in work. Engineering solutions aimed at preventing the upper part of the ladder from slipping while working on the support are presented. The systematization is carried out concerning the available attachments on ladder by the method of coupling with the support. The evaluation of these engineering solutions in various ways of their application is carried out. A mathematical model is proposed for risk assessment when performing work at height using ladders with attachments. The stability of the ladder with the attachment will be higher, the greater the coefficient of friction of the attachment and the less degrees of freedom of movement in the «attachment — support» bundle. An empirical conclusion is made that the safest attachment at the top of the ladder will be the structure that is fixed on the support. The attachment with an anchor point ensures the safety of work at height, but it is not suitable in all cases. There is no universal effective engineering solution to ensure the safety of work at height from the ladder. Technical safety measures have great potential, since they allow eliminating the human factor in this process.

At present, the main prospects for improving the insulating means of respiratory protection are related to the chemical method of oxygen reservation. The arguments in favor of this choice are the high density of oxygen packaging and its self-regulating supply, depending on the physical activity of the person. Usually, the working process in devices on chemically bound oxygen is modeled using mathematical physics methods that solve the so-called sorption dynamics problem. As a result, under given boundary and initial conditions, the concentration of CO2 molecules in the regenerative cartridge turns out to be a deterministic function of time and coordinates. However, the coordinate of the elementary act of sorption is essentially a random variable. The law of its distribution evolves as the absorbing resource of the regenerative cartridge is consumed. Taking into account the above, a probability-theoretic approach to modeling the working process of an insulating breathing apparatus based on chemically bound oxygen was developed. The approach is based on the description by probability theory methods of the random coordinate of the elementary act of chemosorption of a CO2 molecule by potassium peroxide granules and the random lifetime of this molecule in the regenerative cartridge of the respiratory apparatus. The evolution of the initial and central statistical moments of these values is established. The symmetry of their probability density with respect to the permutation of dimensionless arguments is shown, which are the time and distance from the entrance to the regenerative cartridge to the considered layer of chemisorbent. The presence of symmetry increases the speed of numerical experiments by one or two orders of magnitude. Gaussian asymptotics of the process at long times and corrections to it by inverse degrees of dispersion due to asymmetries and excesses of different orders are revealed. This further increases the speed of numerical experiments in computer simulation of the working process of an insulating respirator on chemically bound oxygen.

The problem of energy security of industrial enterprises is considered, which is directly related to the technical condition of 6 kV power cables with impregnated paper insulation. The conclusion is made about the need for a unified approach to the prevention of accidents caused by faults and cable defects. The task is to conduct a study and develop an integral criterion that allows identifying the current technical condition of 6 kV power cables. To carry out these studies, a special experimental setup was created in the diagnostic laboratory of the Ufa State Petroleum Technical University. The developed research method is based on the theory of non-destructive testing. Analysis of the research results based on the analysis of input and output signals of various frequencies, taking into account the characteristics of the power cable, confirmed the fact of changes in the measured values. This indicates the presence of damage and defects inside the cable. Diagnostic parameters were obtained during the research. The relationship between these parameters and the characteristic level of cable defects and damages is established. Using an artificial neural network, integral diagnostic parameters were formed, and an integral criterion was developed. The use of this criterion will allow to identify faults and defects in power cables and track the dynamics of their development, predict the residual resource of cables, and transfer them to maintenance according to their actual condition. All this will further increase the safety and efficiency of electrical equipment operation at the industrial enterprises.

The epileptic power supply in Nigeria is enormously impeding universities’ administrative, academic, and research activities. The diesel generators on which most of these institutions rely as alternative power sources during grid failures are not viable solutions as the grid outage is incessant and the duration usually lasts for hours, at times for days. The effects of these are high running costs and increased environmental pollution. If normal activities in the universities are to continue unhindered and to reduce the health risks associated with the fossil-based generators, there is the need to explore other alternatives such as utilizing the environmentally-friendly, free and abundant renewable resources to meet their electricity demands. The present study uses Hybrid Optimization of Multiple Energy Resources (HOMER) to evaluate two different configurations of a stand-alone diesel generator (DG) system and a hybrid solar photovoltaic(PV)-diesel generator(DG)-battery energy storage (BES) system for sustainable power supply to the Baze University Abuja, Nigeria. The net present cost and levelized cost of energy, operating cost, and carbon dioxide emission of the hybrid PV-DG-BES system are lower by 50%, 30.93%, and 90% respectively when compared to the stand-alone DG system. Therefore, a hybrid solar PV-DG-BES system is a suitable technology to sustainably power the University.

Published: October 2020

In this investigation experiment was carried out in 80 mm diameter swirling pipe jet, where swirl was generated by attaching wedge-shaped helixes in the pipe. All measurements were taken at Re 5.3e4. In the plain pipe jet the potential core was found to exist up to x/D=5 but in the swirling jet there was no existence of potential core. The mean velocity profiles were found to be influenced by the presence of wedge-shaped helixes in the pipe. The velocity profiles indicated the presence of sinusoidal flow field in the radial direction existed only in the near field of the jet. This flow field died out after x/D=3 and the existence of jet flow diminished after x/D=5.

Published: October 2020

In this work, we will simulate the motion of a single underwater sensor knowing the current velocity to predict its location and velocity during certain time frame using a numerical approach of non-linear time-dependent partial differential equations and develop numerical computer programming code to solve the equations.

The underwater sensor are used to collect data for many scientific and practical reasons all the sensor collected data without specifying the sensor location and time will be missing lowers valuable information and by simulating the sensor motion numerically will have many values and impact on the underwater sensor industries as this will lead to less power consumption sensors with smaller size and less network coverage required.

This paper will study the kinetics of the underwater sensor which will resulted to a set of non-linear time-dependent partial differential equations that can be solved analytically and computer programming simulation is developed to solve the equations and predict the motion of underwater sensor.

Different scenarios considered in the work such as simulating the result for different sensor’s density and the effect on its final position.   Also, the result will include the sensor velocity simulation and comparison with the sea current velocity.

This work is limited to the motion prediction of single underwater sensor and the result is only for mechanical aspect of the problem, the networks connectivity or coverage is out-of-scope.
PRIME NUMBER LAW. DEPENDENCE OF PRIME NUMBERS ON THEIR ORDINAL NUMBERS AND GOLDBACH – EULER BINARY PROBLEM USING COMPUTER
Authors: Chermidov Sergey Ivanovich
Published: October 2020

The article considers the methods of defining and finding the distribution of composite numbers CN, prime numbers PN, twins of prime numbers Tw and twins of composite numbers TwCN that do not have divisors 2 and 3 in the set of natural numbers - ℕ based on a set of numbers like Θ = {6∙κ ± 1, κ ∈ ℕ}, which is a semigroup in relation to multiplication. There has been proposed a method of obtaining primes by using their ordinal numbers in the set of primes and vice versa, as well as a new algorithm for searching and distributing primes based on

a closedness of the elements of the set Θ. It has been shown that a composite number can be presented in the form of products (6x ± 1) (6y ± 1), where x, y ℕ - are positive integer solutions of one of the 4 Diophantine equations: . It has been proved that if there is a parameter λ of prime twins, then none of Diophantine equations P (x, y, λ) = 0 has positive integer solutions. There has been found the new distribution law of prime numbers π(x) in the segment [1 ÷ N]. Any even number is comparable to one of the numbers i.e. . According to the above remainders m, even numbers are divided into 3 types, each type having its own way of representing sums of 2 elements of the set Θ. For any even number in a segment [1 ÷ ν], where ν = (ζ−m) / 6, , there is a parameter of an even number; it is proved that there is always a pair of numbers that are elements of the united sets of parameters of prime twins and parameters of transition numbers , i.e. numbers of the form with the same λ, if the form is a prime number, then the form is a composite number, and vice versa.

Published: October 2020

في ظل ازدياد حالات الكوارث والنزاعات المسلحة وانتشار الاوبئة وما يترتب عليها من مخاطر والتي يدفع ضريبتها في المقام الاول الانسان نظراً الى ما يصيبه من خسائر في الارواح والممتلكات، ناهيك عن تعرض مصالح الدولة لذات المصير، بات نظام الانذار المبكر ضرورة ملحة ينبغي على المجتمع الدولي تفعيله دولياً مع الزام الدول بضرورة تبني انظمة من هذا القبيل، ونقول تفعيله لان هذا النظام موجود اصلاً وقد تناولته بالتنظيم العديد من الاتفاقيات نذكر منها اتفاقية التبليغ المبكر عن الحوادث النووية لعام 1986، فضلاً عن العديد من الاتفاقيات الاخرى، الى جانب تبني هذا النظام في اللوائح الصحية الدولية لسنة (2005)، كما ثمة العديد من المؤتمرات العالمية والاقليمية التي اكدت من خلال الاعلانات الصادرة عنها على ضرورة تبني نظام الانذار المبكر من الكوارث.

ولعل من اهم ما توصل اليه المجتمع الدولي من تطور في ميدان اعمال نظام الانذار المبكر هو وضع اطار عمل (هيوجو) للفترة ( 2005 – 2015) ، واطار عمل سينداي للفترة (2015 – 2030) واللذان تبنيا اولويات اعتبرت بمثابة مرتكزات يقوم عليها هذا النظام .

الا انه وبالرغم من كل تلك الجهود فأن الواقع يعكس عدم جدوى هذه الالية في الحد من مخاطر الكوارث ويعود السبب الرئيسي في ذلك الى وجود العديد من المعوقات ، البعض منها يرجع الى ضعف الدعم المادي وعدم التزم الدول بتشريع قوانين خاصة بهذا النظام فضلاً عن امتناع بعض الدول عن التبليغ ، كل هذه المعوقات تدفعنا الى الاقتراح بضرورة تفعيل هذا النظام بشكل جدي من قبل المجتمعين الداخلي والدولي، لما له من دور في الحد من الكوارث بكافة اشكالها وما ينجم عنه من مخاطر.

RESUMOO artigo analisa os impactos causados pelo processo de urbanização nacional relacionados à moradia, com base nos estudos de Douglass North, da Nova Economia Institucional (NEI). A metodologia é caracterizada por um estudo exploratório a partir de uma revisão de literatura referente ao processo de urbanização brasileiro e a abordagem sobre o direito de propriedade sob a perspectiva da teoria economia institucionalista. Os resultados teóricos e empíricos acumulados pela NEI oferecem um instrumental importante para uma melhor compreensão das várias interfaces entre o sistema econômico e as instituições legais e jurídicas que condicionam as atividades e transações econômicas relacionadas à moradia. As ideias de North mostraram-se adequadas na discussão do tema, haja vista que se o direito de propriedade for mais bem definido, atribuído e garantido, nessas comunidades, menores serão os custos de transação e, consequentemente, maior será o valor do ativo e da renda do proprietário deste.Palavras-chave: Urbanização brasileira. Dinâmica populacional.

The methodology is characterized by an exploratory study based on a literature review regarding the Brazilian urbanization process and the approach on property rights from the perspective of institutionalist economics theory. The theoretical and empirical results accumulated by the NEI provide an important tool for a better understanding of the various interfaces between the economic system and the legal and juridical institutions that condition the economic activities and transactions related to housing. The ideas of North were adequate in the discussion of the subject, since if the property rights are better defined, assigned and guaranteed in these communities, the lower the transaction costs and, consequently, the greater the value of the asset and of the owner's income.Keywords: Brazilian urbanization.

PENGARUH PEMBANGUNAN TURAP BETON TERHADAP EKOLOGI KAWASAN PERMUKIMAN DI TEPIAN SUNGAI KAPUAS PONTIANAK
Authors: Fibrianto Jockie Zudhy , Ikram Muhammad Subhansyah
Published: October 2020

Untuk menjaga daratan dari abrasi salah satu rekayasa teknik adalah menggunakan turap beton. Pembangunan turap beton hampir disepanjang tepian Sungai Kapuas Pontianak, menjadi program pemerintah daerah untuk menciptakan “Pontianak Waterfront City”. Namun dalam pelaksanaannya memiliki dampak terhadap ekologi khususnya pada kawasan permukiman di tepian Sungai Kapuas, hal ini terjadi karena sistem sanitasi baik limbah cair dan padatnya langsung dialirkan ke sungai, dengan asumsi akan terbawa oleh arus pasang-surut Sungai Kapuas. Dengan adanya turap limbah tersebut tertahan di lingkungan permukiman, kondisi ini tentunya akan mempengaruhi kualitas air dan ekologi pada kawasan. Dengan menggunakan metode pengukuran kualitas air sungai yaitu TSS, TDS, DO, COD dan BOD, yang diidentifikasi dan diukur, kemudian dilanjutkan dengan analisa kawasan, melalui pendekatan dari aspek fisik, aspek biologi dan aspek kultural. Analisa kawasan dilakukan dengan membandingkan dua lokasi kawasan permukiman di tepian Sungai Kapuas yang memiliki turap dan yang tidak memiliki turap. Hasil yang didapat adalah kawasan permukiman dengan turap beton, memiliki nilai TDS yang tinggi, DO yang rendah, COD yang tinggi dan BOD yang rendah dibandingkan kawasan permukiman tanpa turap. Sehingga pembangunan turap beton pada kawasan permukiman di tepian Sungai Kapuas akan berdampak terhadap ekologi pada kawasan tersebut. THE IMPACT OF CONCRETE SHEET PILES DEVELOPMENT ON THE ECOLOGY OF SETTLEMENT AREA AT THE WATERFRONT OF PONTIANAK KAPUAS RIVERTo protect the land from abrasion, one of the engineering techniques is to use a sheet pile. The construction of concrete sheet piles along the waterfront of the Pontianak Kapuas River has become a regional government program to create the "Pontianak Waterfront City." However, in its implementation, it has an impact on ecology, especially in residential areas on the waterfront of the Kapuas River; this occurs because the sanitation system, both liquid, and solid waste, is flowed directly into the river, assuming the tides of Kapuas River will carry it. With sheet pile the waste material retained in a residential environment, this condition will undoubtedly affect the water quality and the ecology in the area. Using river water quality measurement methods, TSS, TDS, DO, COD, and BOD, identified and measured, then continued with site analysis, with approaches from physical, biological, and cultural attributes. Sites analysis is done by comparing the two settlement areas at the Kapuas River's waterfront with sheet piles and without sheet piles. The results obtained are settlement areas with concrete sheet piles, which have high TDS values, low DO, high COD, and low BOD compared to settlement areas without sheet piles. The construction of concrete sheet piles in settlement areas at the waterfront of the Kapuas River will impact the areas' ecology

The new SARS-CoV-2, responsible for the COVID-19 pandemic, has been threatening public health worldwide for half a year. The aim of this work was to evaluate compounds of natural origin, mainly from medicinal plants, as potential SARS-CoV-2 inhibitors through docking studies. The viral spike (S) glycoprotein and the main protease Mpro, involved in the recognition of virus by host cells and in viral replication, respectively, were the main molecular targets in this study. The best energy binding values for S protein were, in kcal/mol: -19.22 for glycyrrhizin, -17.84 for gitoxin, -12.05 for dicumarol, -10.75 for diosgenin, and -8.12 for delphinidin. For Mpro were, in kcal/mol: -9.36 for spirostan, -8.75 for N-(3-acetylglycyrrhetinoyl)-2-amino-propanol, -8.41 for α-amyrin, -8.35 for oleanane, -8.11 for taraxasterol, and -8.03 for glycyrrhetinic acid. In addition, the synthetic drugs umifenovir, chloroquine, and hydroxychloroquine were used as controls for S protein, while atazanavir and nelfinavir were used for Mpro. Key hydrogen bonds and hydrophobic interactions between natural compounds and the respective viral proteins were identified, allowing us to explain the great affinity obtained in those compounds with the lowest binding energies. These results suggest that these natural compounds could potentially be useful as drugs to be experimentally evaluated against COVID-19.

The experimental execution of chemical reactions is a context-dependent and time-consuming process, often solved using the experience collected over multiple decades of laboratory work or searching similar, already executed, experimental protocols. Although data-driven schemes, such as retrosynthetic models, are becoming established technologies in synthetic organic chemistry, the conversion of proposed synthetic routes to experimental procedures remains a burden on the shoulder of domain experts. In this work, we present, for the first time, data-driven models for predicting the entire sequence of synthesis steps starting from a textual representation of a chemical equation. We generated a data set of 693,517 chemical equations and associated action sequences by extracting and processing experimental procedure text from patents, using state-of-the-art natural language models. We used the attained data set to train three different models: a nearest-neighbor model based on recently-introduced reaction fingerprints, and two deep-learning sequence-to-sequence models based on the Transformer and BART architectures. When evaluated on the ground truth data, the best performing model (transformer) achieves an accuracy of 72.7% for single action predictions, and a 100% match of the full action sequence for 3.6% of experimental procedures. An analysis by a trained chemist revealed that the predicted action sequences are adequate for execution without human intervention in more than 50% of the cases.
Bridged Bicyclic Building Block Upgrading: Photochemical Synthesis of bicyclo[3.1.1]heptan-1-Amines
Authors: Harmata Alexander , Sowden Madison , Stephenson Corey
Published: October 2020

Compounds containing bridged bicyclic carbon skeletons are desirable building blocks for medicinal chemistry. However, as a result of their inefficient, linear syntheses, commercially available compounds of this sort are plagued by high costs and/or a lack of diversity in substitution patterns. Herein we report the conversion of the readily available bicyclo[1.1.1]pentan-1-amine substructure to a wide range of poly-substituted bicyclo[3.1.1]pentan-1-amines using imine photochemistry. To our knowledge, this is the first reported method to convert the bicyclo[1.1.1]pentane skeleton to the bicyclo[3.1.1]heptane skeleton. Hydrolysis of the imine products gives complex, sp3-rich primary amine building blocks.
Reasoning, Granularity, and Comparisons: A Unit-Based Method for Characterizing Students’ Arguments on Chemistry Assessments
Authors: Deng Jacky M. , Flynn Alison B.
Published: October 2020

In a world facing complex global challenges, citizens around the world need to be able to engage in argumentation supported by scientific evidence and reasoning. In order for coming generations to have proficiency in this skill, students must be provided opportunities to develop and demonstrate argumentation science classrooms, including on assessments. For example, students can be provided with assessment items that explicitly ask them to reason from evidence. Alongside these assessment items, researchers and educators need methods to evaluate students’ written arguments. In this study, we present a unit-based method for characterising students’ arguments on chemistry assessments. This unit-based method identifies units (links, concepts, comparisons) within one’s argument, and uses these units to evaluate an argument based on three dimensions: reasoning, granularity, and comparisons. To demonstrate this method, we report our findings from using it evaluate two different organic chemistry questions: (1) justifying why one of three bases would drive an equilibrium towards products (N = 170), and (2) justifying why one of two reaction mechanisms is more plausible (N = 122). Lastly, to translate the method into a rubric for educators, we compare a scoring system based on the unit-based method against a traditional scoring system. As well, we report our findings from interviews with educators (N = 4) to invite their feedback on the rubric and its dimensions.

The development of a versatile platform for the synthesis of 1,2-difunctionalized bicyclo[1.1.1]pentanes to potentially mimic ortho/meta-substituted arenes is described. The synthesis of useful building blocks bearing alcohol, amine, and carboxylic acid functional handles has been achieved from a simple common intermediate. Several ortho and/or meta-substituted benzene analogues as well as simple molecular matched pairs have also been prepared using this platform. In-depth biological and computational studies are currently in progress to validate the ortho and/or meta-character of these new bioisosteres. Results of these investigations will be reported in due course.
Poetry and process: Glad in the Ruthless Furnance / Poésie et procédé : être joyeux dans l’impitoyable fournaise
Authors: Donawa Wendy
Published: October 2020

Abstract: Poets use sensory imagery and perception, memory and experience, free association and contemplation to join psychic and material worlds, and to honour both emotional and discursive truths. Through multiple drafts, free-writing and research, the author unpacks her own reflections and poems to demonstrate the process by which intuition and personal insight are crafted for public understanding. This poetic process suggests that scholarly discourses of the arts and the humanities need not always fall into the quantitative/qualitative binary, but that both heart and mind are required to some degree in the seeking of wisdom.Keywords: imagery, craft, metaphor, cadence, tone, sensory perception, memory, intuition, contemplationRésumé : Les poètes utilisent l’imagerie sensorielle et la perception, la mémoire et l’expérience ainsi que l’association libre et la contemplation, pour unifier les univers psychique et matériel et célébrer à la fois les vérités émotionnelles et discursives. Par le biais de multiples ébauches, d’écriture libre et de recherches, l’auteure partage ses réflexions et poèmes pour décrire le procédé par lequel intuition et points de vue personnels sont façonnés dans le but d’être compris par le public. Ce procédé poétique donne à penser que les discours érudits sur les arts et les sciences humaines ne doivent pas obligatoirement être de nature binaire quantitative ou qualitative mais que cœur et esprit sont, dans une certaine mesure, indispensables à la quête de la sagesse. Mots-clés : imagerie, art, métaphore, cadence, ton, perception sensorielle, mémoire, intuition, contemplation.

Authors: Leggo Carl D , Irwin Rita L.
Published: October 2020

Abstract: We have been making art and writing poetry together for many years. As colleagues in arts-based education research, we have journeyed together with many colleagues and students, in many research projects, in dreaming possibilities for teacher education, in promoting the value of a/r/tography as a way of understanding our intricate and composite identities as artists, researchers, and teachers. For us, seeing is not solitary. Instead, seeing is a creative practice of living well with one another in relationship to the world. So, in this article, Rita L. Irwin’s photography and Carl Leggo’s poetry come alongside in order to perform ways of attending.Keywords: A/r/tography; art; Photography; Poetry; Attending; Ekphrasis. Résumé : Nous conjuguons art et poésie depuis longtemps déjà. À titre de collègues de recherche pédagogique à caractère artistique, nous avons évolué auprès de nombreux homologues et étudiants dans le cadre de projets de recherche, en quête d’avenues de formation des éducateurs et dans le but de promouvoir le potentiel de l’a/r/tographie pour mieux comprendre nos identités composites et complexes en tant qu’artistes, chercheurs et enseignants. L’observation n’est pas pour nous un acte solitaire mais bien la pratique créatrice de la cohabitation fructueuse face à notre environnement. Cet article conjugue donc la photographie de Rita L. Irwin et la poésie de Carl Leggo pour proposer des modes de participation.Mots-clés : a/r/tographie, art, photographie, poésie, participation, ekphrasis.

The Professional Training of Museum Educators in Canada / La formation professionnelle en éducation muséale au Canada
Authors: Lachapelle Richard , Zimmer Thibault , Sinner Anita
Published: October 2020

Abstract: A review of museum training programs was undertaken to assess the current state of professional museum education training in Canada. Out of 18 post-secondary museum studies programs, four programs include one museum education course and two programs include two courses. We found no evidence of museum education content in any of the eight Canadian curatorial practice programs. In terms of specialized programs, a Masters of Museum Education program has existed at UBC since 2012. Another Canadian university is currently examining the possibility of setting up a program. We conclude that the offer of professional museum education training in Canada is slowly improving. Keywords: Museum Education; Museum Education Training; Post-secondary Professional Education; Professionalization of Museum Education. [1] This research has been made possible by a grant from the Social Sciences and Humanities Research Council of Canada.Résumé : Une analyse des différents programmes de formation muséale a été menée pour déterminer l’état actuel de la formation muséale professionnelle au Canada. Quatre des dix-huit programmes d’études muséales postsecondaires proposent un seul cours d’éducation muséale tandis que deux programmes en offrent deux. Nous n’avons trouvé aucune trace de contenu d’éducation muséale parmi les huit programmes canadiens de pratique des conservateurs. En ce qui concerne les programmes spécialisés, l’Université de la Colombie-Britannique propose depuis 2012 un programme de maîtrise en éducation muséale. Une autre université canadienne étudie présentement la possibilité de mettre sur pied un tel programme. Il semblerait donc que la formation professionnelle en éducation muséale offerte gagne lentement du terrain.Mots-clés : éducation muséale, formation à l’éducation muséale, formation professionnelle postsecondaire, professionnalisation de l’éducation muséale.[1]Cette recherche a bénéficié d’une subvention du Conseil de recherches en sciences humains du Canada.
