Turbulent Kinetic Energy and Budget of Heterogeneous Open Channel with Gravel and Vegetated Beds
Authors:   Department of Civil Engineering, Ekiti State University, Ado Ekiti, Nigeria, Folorunso OP
Published: July 2021

Turbulent kinetic energy (TKE) and budget are indispensable hydraulic parameters to determine turbulent scales and processes resulting from various and different natural hydraulic features in open channels. This paper focuses on experimental investigation of turbulent kinetic energy and budget in a heterogeneous open channel flow with gravel and vegetated beds. Results indicate the turbulent kinetic energy (TKE) value over gravel region of the heterogeneous bed remains approximately constant with flow depth. The highest turbulent kinetic energy was calculated for flexible vegetation arrangement compared to the rigid vegetation. The estimation of the turbulent kinetic energy budget shows the higher values of turbulence production recorded over the flexible vegetated bed, consequently, the dissipation rate exhibits faster decay of turbulence kinetic energy over the vegetated bed in comparison to the gravel bed.
“Probabilistic Landslide Hazard Methodology, an Application to a Susceptible Area to Landslides in Colombia”
Authors:   Civil Engineer, M.S. Geotechnical Engineering, Street 50 # 15-91 Palermo Neighborhood, Bogota Colombia, Yepes-Heredia Jairo E
Published: July 2021

A Probabilistic method was previously used to perform Probabilistic Hazard Zonation in El Salvador using a new proposed probabilistic methodology (Rodriguez, Yepes 2011). The current project is a case study that uses the same methodology and tries to cover the limitations of the previous and first application, and applied to two historically unstable landslides in Pipiral, an unstable area in the Central Region of Colombia. The susceptibility angle was used as the susceptibility function. Rainfall and earthquakes are considered as landslides triggers. Besides zonation, modeling was performed because the probability model was initially designed to do the zonation of larger areas. A database from “four countries in Central-America and Colombia” of Rainfall Induced Landslides in Fine-grained soils and a database of “historic and worldwide” Earthquake Induced Landslides, were considered to support the model. The intensity-duration-frequency (I-D-F) curves for the Pipiral-Colombia were used to define the probability of occurrence of the critical rainfall, and the seismic hazard analysis of the same area was used to define the probability of occurrence of the critical earthquake.
Uniform Scaling of Physical Units and the Principle of Rationality of Measurement
Authors:   Fachbereich C-Mathematik und Naturwissenschaften, Bergische Universität Wuppertal, Gaussstr. 20, D-42119 Wuppertal, Germany, Buenker Robert J
Published: July 2021

One of the most basic principles in science is the objectivity of measurement of physical properties. According to the special theory of relativity (STR), this ancient principle is violated for observers in relative motion since it predicts that they generally will disagree on the ratios of the lengths of two objects and also on whose clock is running slower at any given time. Both predictions stem from the Lorentz transformation (LT), which is the centerpiece of Einstein's STR. It has recently been pointed out that two of the claims of this theory are mutually contradictory; it is impossible that the rates of two clocks in motion are strictly proportional to one another (time dilation) while one of them finds that two events are simultaneous whereas the other does not (remote nonsimultaneity). This recognition proves that the LT is not a valid component of the relativistic theory of motion, including its well-known thesis that space and time are not distinct quantities. Instead, it has always been found experimentally that the rates of clocks in motion are governed by a Universal Timedilation Law (UTDL), whereby the speed of the clock relative to a specific rest system is the sole determining factor. A simple way of describing this state of affairs is to say that the standard unit of time in each rest frame is different and increases with its relative speed to the above rest system by a definite factor. The measurement process is thereby rendered to be completely objective in nature. A key goal of relativity theory is therefore to develop a quantitatively valid method for determining this factor. It will be shown that the same factor appears in the true relativistic space-time transformation and that it also plays a key role in the uniform scaling of all other physical properties

Új szövetség a Fekete-tenger két partján? : Törökország és Ukrajna együttműködése
Authors: Egeresi Zoltán
Published: July 2021

Az elemzés a török–ukrán diplomáciai kapcsolatok dinamikáját mutatja be, különös tekintettel az Oroszország 2014-es illegális krími annexiója után eltelt időszakra. Törökország már a 2000-es évek végén és a 2010-es évek elején stratégiai partnerséget alakított ki Ukrajnával a Felsőszintű Stratégiai Együttműködési Tanács létrehozásával, azonban az együttműködés Oroszország krími és kelet-ukrajnai beavatkozása következtében mélyült el. Az orosz Szu–24-es 2015 végi lelövése és az arra válaszként adott orosz szankciók bevezetése katalizálta a két ország kapcsolatát: megszaporodtak a magas rangú találkozók, illetve erősödött a gazdasági és katonai együttműködés. Az elemzés szerint Törökország Ukrajna támogatásával Oroszországot kívánja ellensúlyozni a fekete-tengeri régióban anélkül, hogy – hangos kiállása ellenére – valóban megváltoztatná az erőviszonyokat, egyúttal pedig Ankara arra is törekszik, hogy távol tartson más hatalmakat a térségtől.

Authors: Dziuba Tetiana
Published: July 2021

The relevance of the study is conditioned by the need to strengthen the management function of an agricultural enterprise that focuses on the principles of sustainable development and aims to modernise accounting and analytical support for managing economic potential. The purpose of the study is to form a strategy for the desired improvement of accounting and analytical support of the enterprise with an emphasis on: reporting on sustainable development; expansion of the analytical complex of indicators of economic potential, capacity and performance of an agricultural enterprise; improvement of accounting and analytical support of enterprises using this information model through updating the documentation of control and audit. The theoretical and methodological basis was formed by scientific methods based on the dialectic of knowledge and objective laws of the development of the economy, nature, and society. Economic and mathematical modelling, systematisation and synthesis helped to develop a strategy to improve accounting and analytical support for managing the economic potential of agricultural enterprises, taking into account the principles of sustainable development. This type of modelling can help to effectively modernise accounting and analytical support for managing the economic potential for agricultural enterprises. The developed information model of selective adaptation helps managers of various levels to monitor the implementation of business processes for improving accounting and analytical support for economic potential management, assess the degree of achievement of priority goals and compliance with the principles of sustainable development. One of the steps of long-term modernisation of accounting and analytical support for agricultural enterprises through the introduction of sustainable development reporting is proposed, which should include indicators and documents on managing the economic potential, economic capacity, and performance of agricultural enterprises. The advantage of this information model is the ability to calculate the complexity index of transformation of accounting and analytical support for economic potential management using the principles of sustainable development, which shows the level of complexity of future modernisation of these aspects

Published: July 2021

On the territory of Ukraine, for decades, the pig industry has traditionally remained one of the main reserves for ensuring the financial well-being of the population. Among the factors contributing to the profitability of pig breeding enterprises, a significant role is played by the breeding capacity of sows, since it guarantees the receipt of livestock for rearing and fattening. An indisputable condition for ensuring the efficiency of pig production is to increase the fattening and meat characteristics of pigs. With this in mind, the purpose of the study is to investigate the abovementioned economic traits of pigs, which is currently an urgent task. The research was preceded by the establishment of three groups of sows and young stock, numbering 10 animal units each, located in similar economic conditions. According to the investigational plan, three groups of pigs are provided depending on the genotype: control group 1 – Large White (LW); experimental group 2 – Landrace (L); experimental group 3 – 1/2LWx1/2L (maternal base – Large White, paternal – Landrace). As a result of the conducted studies, it was found out that the local pig population obtained from crossing purebred animals of the Large White and Landrace breeds prevailed in terms of productivity over the original parent forms. From them, on average for three farrowing operations, the largest number of piglets at birth and the highest multiplicity were obtained. An unreliable correlation was found between the characteristics of the reproductive ability of sows and the number of farrowing. The correlation coefficient between the farrowing number and the number of piglets at birth had a negative value – -0.013; for fertility – positive – +0.038; for the offspring size – +0.014; milking capacity – +0.044. At the age of 1, 2, 3, 5, and 6 months, local young stock had the highest live weight, and the Large White pigs had the lowest values with significant differences (P≤0.05-0.001). The Landrace pigs had the highest live weight at birth and at the age of 4 months, and the Large White pigs had the lowest live weight (P≤0.05-0.001). The findings allow increasing the efficiency of the pig industry and prove the expediency of interbreeding in order to increase the economic traits of pigs

Authors: Masliiov Sergey , Korzhova Natalia
Published: July 2021

Today, an increase in the real potential of grain crops, including spring barley, is a necessary condition for elements of crop cultivation technologies. Therefore, given the limited resource potential of spring barley crops, their fastidiousness to the soil, considerable attention should be paid to the photosynthetic potential of plants and the standardised application of mineral fertilisers. The aim of the study was to improve the elements of the technology of growing promising varieties of spring barley by establishing the mineral nutrition effect on the photosynthetic activity of plants in the conditions of the Luhanska Oblast. This study provides examples of improving some technologies for growing promising varieties of spring barley and determines the optimal norms for applying mineral nutrition to ensure the high photosynthetic potential of these plants in the climatic conditions of the steppe zone of Ukraine. It was found that the use of ammonium nitrate had a positive effect on the leaf area, increasing it by 1-2.2 thousand m2 /ha compared to the control for all varieties studied. The combined use of diammonium phosphate and ammonium nitrate contributed to an increase in the leaf area by 2-4. 4 thousand m2 /ha compared to the control variant. Simultaneous application of ActiBION increased the total leaf area for all samples studied by 3.8-6.4 thousand m2 /ha. The best indicators among the studied varieties were observed on the six-row variety Helios and the double-row variety Stalker. The six-row variety Vakula and the two-row variety Adapt showed slightly lower results. Further research implies the study of the influence of photosynthetic activity of promising varieties of spring barley on crop productivity in the steppe zone of Ukraine. The findings can be recommended for production as one of the elements in the technology of growing spring barley in the climatic conditions of the Luhanska Oblast
Evaluation Of Flower Decorative Plants Cultivars Of Nemesia Vent In The Conditions Of Podillia
Authors: Korobko Alina
Published: July 2021

Due to the lack of information about biomorphological features and cultivation technology of species of the genus Nemesia Vent they are still rarely found on the territory of Ukraine and thus are of great interest for cultivation and use for the design of flower beds. The purpose of the scientific work was to analyse the current world assortment of the genus Nemesia Vent, as well as to study the features of flowering, reproductive ability, agrotechnics of growing cultivars of nemesia strumosa, and assess the prospects of their use in decorative gardening in Ukraine. During the research of nemesia strumosa cultivars, laboratory and field research methods were used. It was proved that all the studied cultivars received high ratings of their decorativeness, since the plants under the experimental conditions had well-developed inflorescences, abundant and long-lasting flowering. The plants retained the brightness of their colour throughout the entire period of the flower's life, adapted well to growing conditions, were practically not affected by diseases, and in general were quite resistant to unfavourable conditions. The Orange Prince cultivar proved to be the best of all the cultivars studied in terms of the duration and intensity of flowering, which reached its maximum values on the 60th day from the beginning of the phase with the number of 35 flowers per plant. The studied cultivars can be used in greening health complexes, recreation areas, office territories, adjacent territories, as well as in the design of various types of flower beds. The results of the obtained research are primarily necessary when choosing use cases, developing agricultural technology and breeding programmes, and for carrying out research work aimed at meeting the needs of horticulture. Considering that they are grown both for the needs of the protected ground and open gardening, the study of these issues is a significant contribution for botanical science in general, primarily for decorative gardening in Ukraine, as well as for practical floriculture and landscape design

AS ÁGUAS FLUVIAIS NA NOVA CAPITAL DE MINAS GERAIS (1890/1895): UMA ANÁLISE GEOHISTÓRICA
Authors: Borsagli Alessandro
Published: July 2021

Uma das condicionantes da escolha do arraial de Belo Horizonte para sediar a nova capital foi a sua rede hidrográfica, item considerado de grande importância para o desenvolvimento e salubridade da cidade planejada. O presente artigo busca analisar a rede hidrográfica do sítio escolhido a partir da perspectiva geohistórica, na qual a maioria dos cursos d’água foram desconsiderados na elaboração da planta da Cidade de Minas, onde apenas o ribeirão Arrudas foi oficialmente inserido no traçado geométrico, legando as administrações municipais a elaboração de um plano de intervenção fluvial para os rios urbanos de Belo Horizonte. A análise de intervenções na rede hidrográfica em diversas cidades no período abordado permitiu a compreensão do contexto no qual se planejou a nova capital de Minas Gerais, assim como os preceitos que nortearam os estudos realizados.

O controle jurídico da omissão estatal pela norma da proporcionalidade
Authors: Freitas de Almeida Luiz Antônio
Published: July 2021

A norma da proporcionalidade, originariamente usada como padrão de controle jurídico no direito administrativo, foi importada desse ramo do direito para o direito constitucional, especialmente com o intuito de examinar e conter restrições excessivas aos direitos fundamentais. Se esse campo de aplicação da proporcionalidade encontra maior consenso no âmbito da doutrina e da jurisprudência, a parte menos explorada do seu uso está na sua adequação ou não para o escrutínio das omissões estatais, ou seja, verificar se houve um déficit de proteção por parte do Estado.

Este artigo tem o propósito de defender a possibilidade de sindicar os deveres positivos do Estado pela norma da proporcionalidade, examinando sua estruturação e as modificações necessárias nos seus testes, a fim de desempenhar com maior racionalidade essa tarefa, bem como posicionar-se sobre os diferentes campos de aplicação da proporcionalidade como proibição do excesso e da proporcionalidade como proibição do defeito e a articulação entre essas duas dimensões ou facetas da norma da proporcionalidade.

EFEITO DA APLICAÇÃO DE BORO NA PRODUTIVIDADE DO GIRASSOL
Authors: Cunha Letícia do Socorro , Júnior José Barbosa Duarte , Shimada Belmiro Saburo , Simon Marcos Vinícius
Published: July 2021

Introdução: O boro possui grande relevância na cultura do girassol, pois é o micronutriente que mais limita o desenvolvimento desta cultura. Logo, para que a cultura possa expressar todo o seu potencial produtivo, o suprimento de água e nutrientes deve ser adequado desde o início do seu desenvolvimento, principalmente a partir da emissão do botão floral, quando inicia o período de maior crescimento, acompanhado do aumento no consumo de água e da demanda nutricional. Objetivos: O trabalho teve como objetivo fazer uma revisão bibliográfica sobre, a aplicação de boro na cultura do Girassol. Material e métodos: O estudo foi desenvolvido com base na revisão de literatura e pesquisas relevantes sobre a adubação com boro. Resultados: A disponibilidade dos nutrientes abaixo dos mínimos prejudica diretamente a produção, pois suas necessidades nutricionais serão supridas adequadamente, resultando na deficiência nutricional. O girassol é sensível a níveis baixos de boro no solo. Em solos pobres em boro, recomenda-se a aplicação de 1,0 a 2,0 kg ha-1 do elemento mediante a adubação de base ou de cobertura. A cultura é muito responsiva à aplicação de boro, podendo atingir produtividades mais elevadas a partir da aplicação de doses superiores a 1,0 kg ha-1 de boro. A dose de 4,0 kg ha-1 de boro obteve resultados maximizados relacionados a produtividade e o potencial de produção de óleo. Em condições de deficiência, pode causar diversos distúrbios fisiológicos como, por exemplo, a inibição a elongação das raízes devido a problemas na divisão celular e elongação das células, tornando-as grossas e com as pontas necróticas. Conclusão: Contudo, há uma grande carência de estudos que abordem os efeitos do uso de boro, de forma a otimizar o desenvolvimento e o desempenho agronômico da cultura.

Development of a method to fix a Boron-based preservative into timber
Authors:   , Govender Kesunathan
Published: July 2021

Boron, in spite of its exceptional properties as a timber preservative, is not widely used for this purpose. The three key agents that contribute to the destruction of timber are insects, fungi and ultraviolet radiation. Boron is a good fungicide and insecticide and the acrylic/styrene polymer blend resists ultraviolet attack. Treating timber with boron compounds is very easy and, in most instances, does not require sophisticated equipment. The movement of boron into timber is diffusion driven and requires moisture of between 30-50% in the timber. Unfortunately, this superb mobility of boron results in one major disadvantage, namely, the leaching of boron when moisture enters timber. Various methods have been used to impede the movement of boron out of timber (wax coating, paints, varnishes and water-based polymer coatings. None of them have been completely successful. For instance, varnishes, used to prevent boron from leaching out of timber are unsuitable because they also prevent moisture leaving the timber. This results in blistering of the coatings used to contain the boron. In this project, an all-in-one system was developed by systematically varying the nature of the boron compound and the polymer. The successful formulation, which contained disodium octaborate tetrahydrate, as the source of boron and a styrene acrylic polymer blend, has been found to: Allow the uninhibited diffusion of boron into timber. Form a clear continuous polymer film on curing on the surface of the timber. o Display good resistance to ultraviolet attack on the polymer and the timber substrate The product developed has been formulated with the following concentrations: 60 grams per litre of boric acid equivalent 150 grams per litre of boric acid equivalent 200 grams per litre of boric acid equivalent The efficiency of the acrylic/styrene polymer barrier was shown by performing qualitative tests for the presence of boron on the surface of the timber treated with the all-in-one formulation. Furthermore, leaching tests were performed by submerging the treated timber in water and thereafter, analyzing the water for leached boron at regular intervals. The results of these tests showed that the new formulation (60 gIL, 150 gIL and 200 gIL) is suitable for treatment of timber that is destined for above - ground applications. The preservative containing a concentration equivalent to 60 gIL of boric acid was sufficient for remedial treatment. The preservative containing an equivalent of 150 gIL and 200 g/L of boric acid was ideal for treating freshly felled timber. The patent application for this preservative has been accepted.
Elucidation of microbiological-biochemical relationships in denitrification occurring during activated sludge treatment
Authors:   , Drysdale Gavin David
Published: July 2021

Up until now extensive work has been done to develop kinetic models and related software that can be used successfully to simulate and design nitrification denitrification (ND) and nitrification denitrification biological excess phosphorus removal (NDBEPR) systems for efficient nitrogen removal. The denitrification kinetics of these systems have primarily been determined and attributed to the ordinary heterotrophic bacteria, now also known as the OHO fraction, otherwise not involved in biological excess phosphorus removal. However, denitrification kinetics determined for ND systems have been found to vary considerably at times when applied to NDBEPR systems because of varying OHO active fraction estimates and the unexplained occurrence of anoxic phosphorus removal and anysuccess achieved to date has been some what fortuitous. Ultimately variations in process performance and kinetics are attributable to inadequate control and lack of understanding of the ecological, physiological and biochemical activities of constituent microorganisms. There is growing concern and movement towards a better understanding of the microbial community within activated sludge in order to gain optimal control of the process.

Ergonomics and Forensic Engineering
Authors: Samaras George , Samaras EA
Published: July 2021

In disputes, forensic engineers routinely investigate available hardware and software and may examine other engineering attributes and activities. Human factors and ergonomic (HF&E) aspects may be considered, but these tend to be more limited or overlooked. This paper discusses an HF&E framework for forensic analysis, including its four major subdisciplines (micro-, meso-, macro-, and mega-ergonomics), the role each plays throughout the product life cycle, and examines their relationship to known and foreseeable use and misuse of a product or system. A taxonomy of errors, including distinguishing features of individual user errors versus system use errors, is presented and then used in a diagnostic rubric developed for forensic engineers to help identify HF&E issues as part of a forensic analysis. A health care setting case study is offered to demonstrate rubric use, but the rubric is generalizable to other domains.
