Prospects for Using Carbon Nanotubes in Precision Instrument Engineering
Authors: Golikov A. , Pankratov V. , Barulina M.
Published: May 2020

This research deals with the prospects for application of modern nanomaterials as exemplified by carbon nanotubes for development of new classes of precision measuring instruments or for significant improvement of the performance of existing sensors and systems based on sensors. Carbon nanotubes have been known since the end of the 20th century, but production of high-quality carbon nanotubes on a commercial scale has become possible relatively recently, owing, inter alia, to researches of Russian scientists. Carbon nanotubes have unique properties which hold much promise for their use in different areas of science and technology. Thus, use of nanotubes in precision instrument engineering can solve a number of problems, such as increase in reliability, accuracy, durability, weight and size reduction, etc. Fiber optic gyroscopes based on microstructured optical fiber are considered in this research as an example to demonstrate that use of carbon nanotubes allows significant reduction of the temperature differences in the fiber and that such reduction, in its turn, leads to lower dependence of the FOG characteristics on the temperature effects under actual operating conditions. A mathematical model of the equivalent thermal conductivity of a microstructured fiber loop, all or some channels of which are filled with carbon nanotubes, has been developed in this research. A comparative analysis has been made of the distribution of heat in coils with the considered and traditional fibers under different temperature effects – harmonic, random and stepped.

Published: May 2020

The issues of physical modeling of the processes of deforming inhomogeneous materials are extremely relevant in the development of adequate models of technological processes for the processing of materials by pressure. The object of research is the technology of draft of inhomogeneous material in a closed die. The subject of the research is the processes of evolution of the structure of inhomogeneous material during its deformation. The paper presents a technique that allows to fix the dynamics of compaction of a inhomogeneous flat sample in the process of its draft in a closed die at different rates of deformation and contact conditions in the system «sample – matrix – punch». As a result of the experimental study of the process of draft of inhomogeneous material in a closed matrix, the data characterizing the pore formation and distribution of forces depending on the friction factor, the deformation rate and the degree of deformation are obtained. A method of estimating changes in the geometric parameters of pores in the deformation process is proposed, which allows to determine the front of the material compaction. The obtained experimental data can be used to construct a model describing the deformation of an inhomogeneous medium taking into account the compressibility of the material.

Authors: Samchenko Svetlana V. , Egorov E.S.
Published: May 2020

This article focuses to influence of a pre-hydrated cement suspensions on hardening cement paste properties investigation. The pre-hydration was occurred by 2-th, 4-th 6-th hours during forced mixing. Changes of particle dispersion caused by hydration were determined. It is shown that by hydrolysis increase particles dispersion and subsequently increases quantity of new hydrate formations. Influence of the pre-hydrated cement suspensions on hardening cement paste properties is determined. It is shown that application pre-hydrated addition leads to increasing a cement paste water demand by 12, 17 and 14% for duration of hydration by 2, 4 and 6 hours consequently and to decreasing setting time. It caused by generating supplementary new formations of crystalline hydrate with subsequently increasing rate cement paste structuration. Rate of hardening was increased with increasing duration of the pre-hydration for 10% pre-hydrated cement addition. Obtained results may recommended the addition of pre-hydrated cement in form of cement suspension as cement gel for concrete nanomodification
Investigation of Welded Joints Made of Construction Steel by the Barkhausen Noise Method
Authors: Nikolaeva E. , Nikolaev A.
Published: May 2020

Steel weld seams are characterized by heterogeneity of their microstructure. Microstructure affects the nature of the distribution, sign and magnitude of residual stresses. In combination with unfavorable factors (low temperature, metal hypoductility and an unsuccessful joint form) residual stresses lead to a decrease of load carrying capacity of a whole structure. In a weld seam residual stresses are distributed in a complex way and can affect the build quality of heavy section welded structures. Monitoring of residual stresses remains a big problem. Residual stresses in welds are often evaluated only by modeling. Unfortunately, all mathematical models describe the stress state of the welded material with low accuracy. Simple quality control, the results of which can be easy interpreted, is necessary. Welded joints made by manual arc welding and by automatic submerged arc welding were investigated. Butt seams of steel sheets of different thickness have been welded. Steel was low-carbon and low-alloyed. It is often used in welded structures for various purposes, including construction, and for pipelines manufacture. The temperature range of welded structures operation is very large – from-70 to 450С. The authors studied the structure of butt weld seams by the Barkhausen noise method, which is interesting as it represents an alternative to the known methods, which characterizes the structure and stress state of material. The relationship between the weld microstructure and magnetic noise is shown. Studies have allowed us to establish the relationship between the structure and magnetic properties and to evaluate the feasibility of applying the Barkhausen noise method to welded structures.
Control of Optical Homogeneity of Lithium Niobate Crystals with Admixtures of Rare-Earth Elements Gd, Er by Laser Conoscopy
Authors: Pikoul O. , Sidorov Nikolay V. , Palatnikov Mikhail N.
Published: May 2020

Interference patterns of single crystals of LiNbO3:Gd, LiNbO3:Er, obtained by laser conoscopy, allow us to estimate the optical homogeneity of the samples under study. The observation of conoscopic patterns of the LiNbO3:Gd single crystal shows that with an increase in the percentage impurity concentration, the anomalous biaxiality in these samples manifests itself to a much greater degree. Anomalous biaxiality for the sample LiNbO3:Er [3.60 wt.%] is present at almost every point of the entrance face, which is manifested in conoscopic patterns in the form of enlightenment and rupture of the “Maltese cross”, which corresponds to the angle 2V~1° between the anomalous axes.
Mechanism of Interaction between Concrete Cement Matrix and Mineral Additive Particles
Authors: Rakhimbaev S.M. , Logvinenko A.A. , Logvinenko M.I.
Published: May 2020

A nature of the forces, which act between the concrete cement matrix and entrained mineral particles (ground additives, fine and coarse additives), has been considered. It has been shown that the adhesion between them is attributable to the forces of different nature. The strongest adhesion between the particles of the hydrated binding material and mineral additives occurs, when materials, which react with calcium hydrate of the pore fluid, are used. The latter includes glassy wollastonite, which is part of granulated blast furnace slag. Even at a temperature of 25 °C, an aggressive interaction between them is observed and firm chemical bonds occur. In such case, the dissociation energy of such bonds ranges from 400 to 500 kJ per bond. Between materials, such as crystalline wollastonite and the concrete cement matrix, there is an epitaxial coalescence of its basal surfaces and tobermorite calcium hydrosilicates formed by the interaction of the binder with water. A direct contact is required between the reacting surfaces for such interaction. This is implemented by virtue of the bond, which is attributable to contraction forces resulting from shrinkage strains of the hydrated particles in the concrete cement matrix. Internal strains of the cement that are attributable to contraction, shrinkage, and carbonization of hydrated compounds result in the cement sheath contracting around the aggregate grains and steel reinforcement. Internal strains of the cement stone can be calculated using the Lame equation. We have reviewed the role of the factors, which are most critical for contraction of the cement ring around coarse particles of the aggregate and for stress-strain properties of artificial conglomerates, which have different composition and purpose.

We consider resonances associated with excited eigenvalues of the cavity of a general Helmholtz resonator with straight neck. Under the assumption that the neck stays away from the nodal set of the corresponding eigenstate, we generalise the optimal exponential lower bound on the width of the resonance, that we have obtained in a previous paper for the ground resonance only.
Li Zehou’s “Harmony is Higher than Justice”: Context and a Collaborative Future
Authors: D'Ambrosio Paul
Published: May 2020

In this paper I will delve into Li Zehou’s idea that “harmony is higher than justice (hexie gaoyu zhengyi 和諧高於正義)”. Firstly, I will situate this proposal within the context of the contemporary debate on harmony and justice in Western and Chinese traditions. The position Li holds generally belongs to those who see justice and harmony as representative of a West-East difference. However, it can be developed to promote a more nuanced understanding. After giving due consideration, brief though it must be, to his argument, I will sketch some of the other major views on the relationship between harmony and justice, providing a critique from Li’s perspective. In the final section I seek to expand on Li’s theory by outlining a more collaborative path for thinking about harmony and justice.
Test of Monetary Approach to Balance of Payments in West Africa Monetary Zone
Authors: Oluwole Foluso Ololade , Oloyede John Adebayo
Published: May 2020

This research tested the monetary approach to Balance of Payment in developing countries of West Africa in order to affirm whether the specified relationship in the approach depicts correctly the actual behaviour of the economies. Time series and cross-sectional data that ranges from 1970 – 2016 were used. The empirical results of the fixed effect model established a significant positive relationship between net domestic credit, interest rate and exports; an insignificant positive relationship between capital movements, imports, income and the dependent variable. Exchange rate, however, had a significant negative relationship with the net foreign assets, while inflation had an insignificant but negative relationship with net foreign assets. The pairwise causality tests indicated a unidirectional relationship between exchange rate, net domestic credit and net foreign assets while the other variables move independently and cannot granger cause net foreign assets. Hence, the study concludes that the Polak model is valid in the West Africa Monetary Zone despite the fact that they are no more operating a fixed exchange rate system. The study suggests that the attention of the monetary authorities and the governments should not only be on decreasing the money supply in the economy, since an increase in net domestic credits has a positive impact on the net foreign assets provided it is channeled towards domestic production.
Questioning the Problematic Nature of School Culture in Elementary Teacher Education
Authors: Meier Lori Turner
Published: May 2020

This essay seeks to serve as both commentary and plea to elementary teacher educators and gatekeepers. It first asks us to consider that the culture of elementary teacher education, while characteristically an honorable and moral vocation, can indeed function as an oppressive and marginalizing force in the development, humanization, and growth of aspiring new teachers. Second, it entreats those who work in teacher education to foster, seek out, and support those individuals who find themselves at the diverse, intellectual, creative, and aesthetic margins of traditional elementary teacher preparation norms. To its detriment, the cultural disenfranchisement of these seemingly unconventional new teachers limits the richness of curriculum possibilities, pedagogy, and identity development towards humanization (Freire, 2000). As Danielewicz (2001) suggests and this essay endeavors to make a central thesis, “Teaching is a moral act. A teacher education program should recognize, celebrate, and honor the intentions of prospective teachers who so often feel committed to improving the lives of others, alleviating social inequalities, and eradicating discrimination” (p. 194).
Teaching as a career choice: A case study on the perceptions of emerging teachers
Authors: Houdyshell Michael
Published: May 2020

As fewer and fewer students choose teaching as a career, the teaching profession struggles to understand how to recruit more students into the field, and prevent current teachers from leaving. Data shows the need for new teachers will continue to increase (Sutcher, Darling-Hammond and Carver-Thomas (2016), while almost 70% of schools reported at least one unfilled vacancy to begin the 2011-12 school year (Malkus, Hoyer, & Sparks, 2015). Teacher preparation programs are also graduating fewer students into teaching (2016). This qualitative case study investigated the perceptions and beliefs of undergraduate students enrolled in an introductory course on teaching. Data from this case study is expected to confirm prior research on the reasons why students choose teaching as a profession, and help teacher preparation programs investigate if students’ perceptions about becoming a teacher have changed. Results from this study support prior research on why students choose to become teachers, but also explores students views on how society views teaching, the continued salary gap with other professions, and the future of teaching.

Effectiveness of Coaching by School Improvement Partners through Good Relationship and Professionalism Skills Practiced
Authors: Mohd Tahir Zalina , Mohd Salleh Nabihah
Published: May 2020

School administrators consisting of Principals and Headmasters (PGB) play a significant role in leading the school to achieve excellence. To ensure that excellence is achieved within the timeframe stipulated, the PGB received guidance from fellow coaches known as School Improvement Partners (SIP). The coaching process requires mutual understanding between the two parties so that it can work smoothly and effectively (Narimawati, 2007) without any conflict of ideologies. This study is to identify the effectiveness of the coaching of SIP through the good relations and professional skills practiced during the ongoing coaching. A total of 212 PGB as respondents and data were analyzed using SPSS version 23 for the descriptive analysis, while AMOS version 22 is used for advanced statistics Structural Equation Modeling. The study found that the goodness of fit model by SIP coaching is good with reading of chi-square/df=2.203, CFI=

.969, p=0.00 and RMSEA=.076. Good relationship with professional coaching sessions have contributed a total of 71% (R2=.71) to the effectiveness of the coaching as well as it helps to increase the PGB confidence in the development of schools. This finding confirms that coaching by SIP directly acts as a catalyst for the success of the school and to complete the needs of mission and vision of the Ministry of Education, Malaysia.

Incidence of exercise-induced pulmonary hemorrhage in racehorses in Puerto Rico
Authors: Morales Valerie , Glass Solineel , De Angel José , Vallejo Bernando , Rodríguez-Carías Abner A.
Published: May 2020

Exercise-induced pulmonary hemorrhage (EIPH) is a very common condition in racehorses and is characterized by an alteration of the respiratory system. Depending on the magnitude, EIPH causes bleeding in lung passages making breathing difficult. EIPH is evaluated by endoscopies on a scale from 0 to 5, with 0 corresponding to no hemorrhage and 5 to a severe condition. In Puerto Rico, the only preventive measure used is the administration of a diuretic 4 h before the race. A data set was analyzed to determine factors associated with the incidence of EIPH and the preventive effect of the diuretic. The data was supplied by Equus PR, Center of Veterinary Medicine, and the factors considered were month of the year, sex (male or mare), distance of the race in meters (C1: 400 to 1,200; C2: 1,300 to 1,400; C3: > 1600), and the use or not of a diuretic. The randomly selected data of 2,632 endoscopies of racehorses running or not that were utilized represented 20% of the total endoscopies recorded in 2014. Of this number 1,377 were from horses within 1 to 3 h after the race, representing 52% of the total. A Chi-square test analysis was performed to determine the frequency of EIPH regarding the factors of month, sex, distance of the race, and use of the diuretic. Of the 1,377 animals, 488 presented some degree of EIPH, equivalent to 35% of the total sample. The percentage of affected horses suffering EIPH severity levels from 1 to 5 was 52.8, 23.6, 13.5, 7.3 and 2.8, respectively. The frequency and severity of EIPH were similar (P = 0.435) during the 12 months of the year. Males and mares also had similar (P = 0.587) incidence. Horses running shorter races (C1 and C2) had a higher (P<0.02) incidence of EIPH than those running longer races (C3). The number of healthy horses, or those suffering from the condition, was similar (P = 0.375) regardless of diuretic use. In summary, 35% of the racehorses competing presented some level of EIPH; month of year and sex did not alter the incidence. Horses running shorter distances showed a higher incidence of the condition, and use of the diuretic was not effective as a preventive method for EIPH.

Características fermentativas, consumo voluntario y digestibilidad de nutrimentos de henilaje de sorgo forrajero [Sorghum bicolor (L.) Moench.] y sorgo-sudan (Sudax) fermentado en pacas cilíndricas
Authors: Rodríguez Abner A. , Rodríguez-Santana Wandaliz , Randel Paul F.
Published: May 2020

Se estudió las características fermentativas, el consumo voluntario y la digestibilidad de sorgo forrajero (SF; Sorghum bicolor) y Sudax (SX; híbrido de sorgo x sudan) conservado como henilaje en pacas cilíndricas. Para determinar las características fermentativas del henilaje, se tomaron muestras de forraje fresco y henilado de dos pacas cilíndricas de cada variedad después de cuatro períodos de fermentación (3, 7, 14 y 30 d). Se analizaron las mismas para pH, concentración de ácidos orgánicos y la relación N-NH3/N-total. Los datos se analizaron según el diseño experimental completamente aleatorizado (DCA) con arreglo factorial de 2 (variedades de sorgo; SX y SF) x 5 (días de fermentación) con dos repeticiones por combinación. Para determinar el consumo voluntario (CV) y digestibilidad de la materia seca (MS), proteína bruta (PB) y fibra detergente neutro (FDN) se utilizaron ocho ovinos criollos en una prueba de alimentación. Los 15 d de la prueba fueron distribuidos entre 3 d de adaptación a las facilidades físicas, 7 d de adaptación a la dieta experimental y 5 d de recolección de datos comparativos. A cada ovino se le ofreció diariamente el henilaje correspondiente procedente de dos pacas cilíndricas, a razón de 3% del peso vivo (PV) a base seca y agua ad libitum. Los datos comparativos se sometieron a un análisis de varianza aplicable a medidas repetidas siendo estas las de los días 1 al 5 de recolección fecal. La composición química a base seca del material vegetativo fresco destinado a henilaje de ambos sorgos (MS de 35 o 36%) fue similar con excepción del porcentaje (%) de PB (SX = 5.75; SF = 9.05). No hubo diferencias significativas entre las variedades de sorgo en el pH ni en la concentración de ácidos orgánicos (láctico, acético, propiónico y butírico), ni interacciones significativas entre la variedad y el día de fermentación. El pH en ambas variedades no alcanzó el nivel recomendado (menor de 5) y se observó cierta acumulación de amoníaco, lo que indica una fermentación inestable. Hubo diferencias significativas (P = 0.05) a favor de SF sobre SX en el CV de MS, PB y FDN; también, en la digestibilidad de MS (SX = 41.92%; SF = 64.90%) y PB (SX = 47.09%; SF = 70.68%), pero no de FDN. En resumen, al conservarse como henilaje en pacas cilíndricas, las dos variedades de sorgo mostraron características fermentativas pobres, con valores de pH mayores de 5 y poca producción de ácido láctico. Las ventajas en CV y digestibilidad de MS y PB indicaron mayor valor nutritivo de SF que de SX.

Published: May 2020

The objective of this study was to evaluate the effect of two additives: one of enzymatic nature [Dyadic® Cellulase PLUS (ENZ)] and liquid urea nitrogen (LU) on crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), voluntary intake (VI) and digestibility of treated bluestem grass (BGH; Dichanthium annulatum) hay fed to rams. Nine young rams were used in a 3 x 3 latin square design with the three treatments: BGH without additive (CON), and with added ENZ or LU. The additives were sprinkled over the hay 24 hours prior to being offered daily at the rate of 4% of the animal body weight (BW). Application of ENZ resulted in no important change in VI or digestibility of dry matter (DM), CP, NDF or ADF; but ENZ tended to slightly reduce (P menor 0.11) NDF content (73.91 vs. 74.27%), and increase (P menor 0.09) ADF content (44.37 vs. 42.87%). Treatment of BGH with LU increased (P menor 0.01) the content of CP (8.11 vs. 6.41%), tended to depress (P menor 0.11) that of NDF (73.00 vs. 74.27%) and increase (P menor 0.09) those of ADF (43.17 vs. 42.87%) and lignin (6.30 vs. 5.89%). It also increased VI of CP (87.46 vs. 67.25%) and tended (P menor 0.06) to increase VI of DM (1027 vs. 986 g) and CP digestibility (61.11 vs. 53.98%). Daily VI of DM as a percentage of BW was not significantly affected by the treatments (3.13, 2.94 and 3.23% for CON, ENZ and LU, respectively).

Case Study - Presence of Salmonella Species in Coconut after Kerala Flood2018
Authors: Z Abhinsha
Published: May 2020

A case study that accidentally found Salmonella species, a very rarest case, from flood affected Cocosnucifera while processed in frozen food industry. Coconut is actually considered to be safe and contamination free because of its hard-outer covering, amidst the presence of highly nutritive water content. This was proved to be wrong after the identification of different species of bacteria from coconuts collected during the flood period and was identified during the routine tests.
Diversity and equality in honours and awards programs – steps towards a fair representation of membership
Authors: Holmes Mary Anne , Myles LaToya , Schneider Blair
Published: May 2020

Abstract. Honours and awards bestowed by professional societies
recognize and reward members who have advanced the goals and values of that
society. All too often, however, awards reflect a small network of people
who know about the awards and participate in the process. This network works
wonderfully for the people lucky enough to be in it, but typically neglects
the full range and breadth of scholarship and service within the society. We
represent a combined 15+ years' experience on the honours' committee
for a large professional society (the American Geophysical Union) and here
offer strategies to increase the representation of honourees. Women
represented less than 20 % of awardees when we first became
committee members in 2008; women represented 50 % of awardees in
2019. There is still much to do to ensure that members from other typically
under-represented groups (non-US members, members from under-represented
races/ethnicities) are truly represented and honoured for outstanding
science and service. We recommend forming canvassing committees that will
scour the literature, conferences, and membership lists for appropriate and
otherwise overlooked nominees; providing implicit bias training to selection
committees; and ensuring selection committees focus on the criteria for the
award rather than non-pertinent, often personal, information, as well as additional
strategies that allow us to recognize our worthy colleagues.
Implementation and assessment of a carbonate system model (Eco3M-CarbOxv1.1) in a highly-dynamic Mediterranean coastal site (Bay of Marseille, France)

Abstract. The Bay of Marseille (BoM, France) is impacted by the urbanized and industrialized Aix-Marseille Metropolis, which is subject to significant increases in anthropogenic emissions of CO2. A carbonate chemistry balance module has been implemented into a biogeochemical model of the planktonic food web. The resulting model, named Eco3M-CarbOx includes 22 states variables that are dispatched into 5 compartments: phytoplankton, heterotrophic bacteria, detritus, dissolved organic and inorganic matter. The model suggests that the variability of the dissolved inorganic carbon system is mainly driven by the seawater temperature dynamics. A seasonal trend is identified by the model and it shows that, during the mixed water column period, the BoM is a sink for atmospheric CO2 and a net autotroph ecosystem, while during stratified water column period, the BoM is a source of CO2 to the atmosphere and a net heterotroph ecosystem. External forcings have an important impact on the carbonate equilibrium. Wind events change seawater temperature quickly, as during upwelling, for which the BoM waters change within a few days from a source of CO2 to the atmosphere to a sink into the ocean. Moreover, the higher the wind speed is, the higher the air-sea CO2 gas exchange fluxes are. The river intrusions with nitrate and alkalinity supplies lead to a decrease in the pCO2 value, favoring the conditions of a sink of atmospheric CO2 into the BoM. The nearby highly urbanized environment of the Aix-Marseille metropolis produces strong atmospheric values of CO2, also favoring the conditions of a sink of atmospheric CO2 into the waters of the BoM.
Model-driven optimization of coastal sea observatories through data assimilation in a finite element hydrodynamic model (SHYFEM v.7_5_65)
Authors: Ferrarin Christian , Bajo Marco , Umgiesser Georg
Published: May 2020

Abstract. Monitoring networks aims at capturing the spatial and temporal variability of one or several environmental variables in a specific environment. The optimal placement of sensors in an ocean or coastal observatory should maximize the amount of collected information and minimize the development and operational costs for the whole monitoring network. In this study, the problem of the design and optimization of ocean monitoring networks is tackled throughout the implementation of data assimilation techniques in the Shallow water Hydrodynamic Finite Element Model (SHYFEM). Two data assimilation methods – Nudging and Ensemble Square Root Filter – have been applied and tested in the Lagoon of Venice (Italy), where an extensive water level monitoring network exists. A total of 29 tide gauge stations were available and the assimilation of the observations result in an improvement of the performance of the SHYFEM model that went from an initial root mean square error (RMSE) on the water level of 5.8 cm to a final value of about 2.1 and 3.2 cm for the two data assimilation methods, respectively. In the monitoring network optimization procedure, by excluding just one tide gauge at a time, and always the station that contributes less to the improvement of the RMSE, a minimum number of tide gauges can be found that still allow for a successful description of the water level variability. Both data assimilation methods allow identifying the number of stations and their distribution that correctly represent the state variable in the investigated system. However, the more advanced Ensemble Square Root Filter has the benefit of keeping a physically and mass conservative solution of the governing equations, which results in a better reproduction of the hydrodynamics over the whole system. In the case of the Lagoon of Venice, we found that, with the help of a process-based and observation-driven numerical model, two-thirds of the monitoring network can be dismissed. In this way, if some of the stations must be decommissioned due to a lack of funding, an a-priori choice can be made, and the importance of the single monitoring site can be evaluated. The developed procedure may also be applied to the continuous monitoring of other ocean variables, like sea temperature and salinity.
