A Discussion Regarding the Application of the Hertz Contact Theory on Biological Samples in AFM Nanoindentation Experiments
Authors: Kontomaris Stylianos Vasileios , Stylianou Andreas , Nikita Konstantina S. , Malamou Anna
Published: January 2020

Background:

Atomic Force Microscopy (AFM) Nanoindentation procedure regarding biological
samples poses significant challenges with respect to the accuracy of the provided results. These
challenges are related to the inhomogeneity of biological samples, various uncertainties in experimental
methods and certain approximations regarding the theoretical analysis. The most commonly
used theoretical model for data processing at the linear elastic regime regarding biological samples is
the Hertz model.

Objective:

This paper focuses on the investigation of the resulting errors of the basic equation of the
Hertz theory that depend on the ratio, indentation depth/indenter’s radius regarding the Young’s modulus
calculation.

Methods:

An extended new equation is derived which takes into account the influence of the indentation
depth/indenter’s radius ratio on the calculation of the Young’s modulus and can be easily used for
calculations. The derived equation is further combined with equations which take into account the
shape of the sample.

Results:

Several examples in the literature that do not take into account the value of the ratio indentation
depth/indenter’s radius are reported and the related errors are calculated and discussed. Moreover,
a rational explanation, regarding the extended differences of the Young’s modulus calculations using
the same experimental results when these are processed using the Hertz model and the Oliver & Pharr
analysis (which is the general model that applies for any axisymmetric indenter) is provided.

Conclusion:

A complete and reliable theoretical tool was developed (that takes into account the indentation
depth/indenter’s radius ratio and the shape of the sample) which can be generally applied in order
to reduce the errors produced by the current methodology (Hertz model).
PRINCIPAL DESIGN TECHNIQUES OF RECONCILIATION OF ARCHITECTURE AND NATURE IN CHINESE GARDENS OF SUZHOU
Authors: Shevchenko Marianna
Published: January 2020

Park and garden design of China initially had relatively few strict limitations and rules and there was a great deal of room for creativity. However study of gardens of Suzhou makes it possible to distinguish some basic compositional design features. Those features are: zoning of the park space; designing of routs for visi-tors; creation of contrast and background both in large landscape zones and in small-scale objects; “land-scape borrowing”; use of depth and succession of landscape views. A major challenge for the architect is creation of complex, multi-layered space, where walking routes between the compositional dominants play a significant role. The use of these design features visually extends the garden space, gives the visitor choice between several routes and enriches content of the garden. Besides, several main design objects can be dis-tinguished, such as: large and small water bodies; artificial mountains and stone groups; garden structures, including pavilions, terraces, towers and galleries; decorations and vegetation. Individual design objects and in particular the architectural structures allow us to elaborate the garden space in more detail. Chinese park is inconceivable without the synthesis between the nature and architecture. The acquisition of basic compositional design features allow us not only to better understand the organization of private gardens in China, but also to use them in own design practice.

Authors: Glinyanova Irina , Azarov Valery , Fomichev Valery
Published: January 2020

Fine dust: (PM2.5, PM10) is a priority pollutant that contributes to the development of numerous dis-eases in urban areas. The purpose of this scientific work is to study the dispersed composition of dust parti-cles on the leaves of apricot trees (Prúnus armeníaca) in the residential zone of Volgograd. The novelty of the work lies in the study of the dispersed composition of dust particles on the leaves of apricot trees (Prúnus armeníaca) in the residential zone in the city of Volgograd near the construction industry enterprise, me-chanical engineering, leather production and railway transport line in comparison with the conditionally clean (control) zone of the SNT “Orocenets” ”(Sovetsky District, Volgograd) from the standpoint of random functions expressed by integral distribution curves of the mass of particles over their equivalent diameters. As a result of the research, the dispersed composition of dust on the leaves of apricot trees (Prúnus ar-meníaca) in the residential area of Volgograd was revealed. Fine particles were found: PM2.5, PM10 in each of the studied points, which by their values, both in their number and mass fraction, significantly exceed the data on fine dust in a conditionally clean area (control) in the SNT “Oroshanets” (Sovetsky district Volgo-grad), which creates certain environmental risks for local residents. The dispersed analysis of particles from the standpoint of random functions in the future will allow with a sufficiently high degree of accuracy to pre-dict the dust content of urban atmospheric air in the range of monthly and / or seasonal average values compared to the traditional measurement of fine dust concentration in atmospheric air of the urban environ-ment as the maximum single or daily average. At the same time, further studies of dust on the leaves of plants in an urban environment, namely, the study of the density of its sedimentation, will also reveal a group of ur-ban plants that are best suited to retain PM2.5 and PM10 on leaf plates in this region, which can significantly increase the quality of the atmospheric air of the urban environment and be of a recommendatory nature for the state-owned landscaping services of the city of Volgograd when improving the green areas of a megacity.

OF CERAMIC BRICKS ON THE BASIS OF BEIDELLITE CLAY
Authors: Abdraкhimov Vladimir
Published: January 2020

The efficiency of all industries should be assessed from the point of view of the balance between the weight of the main product and the volume of generated industrial waste, therefore, the aim of the present work is ─ to the receiving using the tonnage of waste fuel and energy complex of ash and slag material and waste chemistry, spent catalyst, one of the most material-intensive products of the national economy ─ a ce-ramic brick on the basis of beidellite clay. Fuel and energy complex is one of the main "pollutants" of the en-vironment. These are emissions into the atmosphere (48% of all emissions into the atmosphere), wastewater discharges (36% of all discharges), as well as the formation of solid waste (30% of all solid pollutants). The basic technical properties of ash and slag material used as autosites and burnable additive and spent cata-lyst, is used as aluminum-containing autosites to increase marochetti brick. Studies have shown that the spent catalyst IM-2201 Novokuibyshevsk petrochemical plant refers to nanotechnology raw materials. The effect of the introduction of nanoscale particles is fundamentally expressed in the fact that not only an additional in-terface appears in the system, but also a carrier of quantum mechanical manifestations. The presence of na-noscale particles in the system increases the volume of adsorption and chemisorption bound water and re-duces the volume of capillary-bound and free water, which leads to an increase in the plasticity of the ceram-ic mass and strength parameters. Ceramic brick with high physical and mechanical properties is obtained on the basis of beidellite clay with the use of ash-slag material and spent catalyst. Innovative proposals for the use of waste fuel and energy complex and petrochemical industry in the production of ceramic bricks, the novelty of which is confirmed by two Patents of the Russian Federation.

METHODS OF ASSESSMENT THE LEVEL OF ENVIRONMENTAL AND ECONOMIC EFFECT DUE TO THE USING OF LOW-SPEED INDIVIDUAL VEHICLES, BY THE EXAMPLE OF THE TOWN OF SERPUKHOV
Authors: Leptiukhova Olga , Utkina Marija
Published: January 2020

For more than half a century bicycle transport demonstrates its effectiveness as one of the elements of the transport network of the city. Currently, vehicles with low-power motors such as electric bicycle, electric scooter, gyrometer, segway, wheelbarrow, scooter motor and others are gaining people's attention. These vehicles can be combined into a group of low-speed individual vehicles (hereinafter - NITS) with similar re-quirements for the operational parameters of urban infrastructure. From the urban point of view, the interest in NITC is that the number of its users has increased significantly in recent years. The article presents the results of a sociological survey of residents of Serpukhov, allowing to assess the current and potential readi-ness of the population to use NITC. The growing popularity of NITC has led to an increase in the environmen-tal and economic effect, which is manifested at a particular level of development of the movement on NITC. The ecological and economic effect of the use of NITC has an extremely positive impact on the improvement of the urban environment. This article provides a list of indicators that reflect the growth in the standards of living of society from movement by the NITC, and the calculation of one of them - the increase in entrepre-neurial activity on the streets with increased traffic to the NITC. Indicators are necessary for calculation of complex criterion of efficiency and safety of street network due to development of the movement by NITC. The result will allow public authorities authorized to make decisions on the strategy of transport policy of cities to quantify the ratio of economic benefits from the development of infrastructure of the NITC with the cost of its construction and operation.
AIR POLUTTION FROM EVAPORATION OF OVERFLOWS AND LEAKS OIL PRODUCTS IN URBAN AREAS
Authors: Khrestenko Ruslan , Sokolova Ekaterina , Azarov Valery
Published: January 2020

Possible locations in the urban environment where overflows and leaks of oil products may occur are indicated. It is noted that the number of overflows and leaks of oil products in the urban environment is large and they occur constantly. The problems of air pollution in the urban environment from overflows and leaks of oil products are considered, on the example of petrol filling station. It is underlined that air most pollute at overflows and leaks of oil products in urban areas due to evaporation of oil products. The insufficiency of the applied measures at overflows and leaks of oil products is indicated. It is noted that the volume of a single leak of oil products is not known, as a rule. It is indicated that the volume of leak characteristic of the urban environment can be up to fifty liters in accordance with the regulatory and technical document. The areas of petrol leaks, which are typical for the urban environment, are calculated. The intensity of evaporation of pet-rol is calculated and mass flows of evaporation petrol from areas of petrol leaks are calculated on the base of obtained values. The quantitative assessment of mass flow of evaporation petrol from areas of leaks is carried out. The dispersion of petrol into atmospheric air from one square meter of leak is calculated by software. It is shown that there is an exceeding of the maximum single maximum permissible concentration of petrol in the atmospheric air at a distance of several tens of meters from the place of the leak even with insignificant single leak of petrol. It is indicated that there are cases when two or more leaks of oil products occur simultaneously in the urban environment. It is underlined that urbanized areas are characterized by a high density of objects where oil products are applied. It is noted that in the atmospheric air in the urban environment there are al-ready background concentrations of petrol, which are close to the maximum permissible concentration of petrol. Increase of the concentration of petrol in the atmospheric air, which comes from the evaporation of the leak, can lead to an excess of the maximum permissible concentration. The task of updating measures to collect overflows and leaks of oil products is set in the urban environment.
The Impact of Hearing Impairment on the Life Trajectories of Aboriginal Children in Remote Australia: Protocol for the Hearing Loss in Kids Project
Authors: Su Jiunn-Yih , He Vincent Yaofeng , Guthridge Steven , Silburn Sven
Published: January 2020

Background

Previous studies have reported a high prevalence of chronic otitis media (OM) and hearing impairment (HI) in Aboriginal children in the Northern Territory (NT) of Australia. Children affected by these disorders are believed to be at increased risk for adverse outcomes in early childhood development, school attendance, academic performance, and child maltreatment and youth offending. However, to date, there have been no studies quantifying the association between HI and these outcomes in this population.

Objective

This study will investigate the association between HI and the 5 outcomes in Aboriginal children living in remote NT communities.

Methods

Individual-level information linked across multiple administrative datasets will be used to conduct a series of retrospective observational studies on selected developmental and school outcomes. The predictor variables for all studies are the results from audiometric hearing assessments. The outcome measures are as follows: Australian Early Development Census results, representing developmental readiness for school, assessed around 5 years of age; Year 1 school attendance rates; Year 3 school-based academic performance, assessed in the National Assessment Program—Literacy and Numeracy; incidence of child maltreatment events (including both notifications and substantiated cases); and incidence of a first guilty verdict for youth offenders. Confounding and moderating factors available for the analysis include both community-level factors (including school fixed effects, socioeconomic status, level of remoteness, and housing crowdedness) and individual-level factors (including maternal and perinatal health and hospital admissions in early childhood).

Results

The study commenced in 2018, with ethics and data custodian approvals for data access and linkage. This has enabled the completion of data linkage and the commencement of data analysis for individual component studies, with findings expected to be published in 2019 and 2020.

Conclusions

This study will provide first evidence of the impact of OM-related HI on the developmental, educational, and social outcomes of Australian Aboriginal children. The findings are expected to have significant implications for policy development, service design, and resource allocation.

Generating Medical Assessments Using a Neural Network Model: Algorithm Development and Validation (Preprint)
Authors: Hu Baotian , Bajracharya Adarsha , Yu Hong
Published: January 2020

BACKGROUND

Since its inception, artificial intelligence has aimed to use computers to help make clinical diagnoses. Evidence-based medical reasoning is important for patient care. Inferring clinical diagnoses is a crucial step during the patient encounter. Previous works mainly used expert systems or machine learning–based methods to predict the International Classification of Diseases - Clinical Modification codes based on electronic health records. We report an alternative approach: inference of clinical diagnoses from patients’ reported symptoms and physicians’ clinical observations.

OBJECTIVE

We aimed to report a natural language processing system for generating medical assessments based on patient information described in the electronic health record (EHR) notes.

METHODS

We processed EHR notes into the Subjective, Objective, Assessment, and Plan sections. We trained a neural network model for medical assessment generation (N2MAG). Our N2MAG is an innovative deep neural model that uses the Subjective and Objective sections of an EHR note to automatically generate an “expert-like” assessment of the patient. N2MAG can be trained in an end-to-end fashion and does not require feature engineering and external knowledge resources.

RESULTS

We evaluated N2MAG and the baseline models both quantitatively and qualitatively. Evaluated by both the Recall-Oriented Understudy for Gisting Evaluation metrics and domain experts, our results show that N2MAG outperformed the existing state-of-the-art baseline models.

CONCLUSIONS

N2MAG could generate a medical assessment from the Subject and Objective section descriptions in EHR notes. Future work will assess its potential for providing clinical decision support.

Authors: Alemu Daniel Solomon , Pykhtina Olga
Published: January 2020

Existing research on faculty mobility generally investigates the issue in the context of Western postsecondary institutions. This study adds to the body of knowledge through studying higher education faculty in six Middle Eastern countries. Participants of the study were higher education faculty members in Bahrain, Kuwait, Oman, Qatar, the Kingdom of Saudi Arabia, and the United Arab Emirates. Out of 600 faculty members initially invited, 139 completed the electronic survey, whichwas administered in the 2017–2018 academic year. The findings show that factors both internal and external to an institution contributed to a faculty member’s decision to stay or leave. It also shows that gender and experience in the GCC Universities had no significant effect on faculty members’ intentions to leave or to stay.

Published: January 2020

Los estudios de dieta alimentaria en murciélagos tienen gran importancia en la dinámica de ecosistemas naturales en la Amazonía peruana. Ello nos motivó a investigar las especies de plantas consumidas por murciélagos frugívoros en bosque de colina baja, río Itaya, Loreto. Para ello, se instalaron 216 redes de neblina en 36 unidades de muestreo entre los meses de junio a diciembre de 2009 aplicando un esfuerzo de 1296 horas/red. Se registraron 20 especies de plantas consumidas por 195 individuos de 15 especies de murciélagos frugívoros. Las plantas consumidas fueron árboles, arbustos y hierbas. Los murciélagos consumieron con mayor frecuencia especies de las familias Moraceae, Araceae, Cyclanthaceae y Urticaceae. Según el índice de importancia del dispersor (IID) las especies de murciélagos más representativas fueron Rhinophylla pumilio y Artibeus obcurus. El estudio evidenció 13 nuevas plantas consumidas por murciélagos para el Perú y el Neotrópico, lo cual incrementa la importancia de estos mamíferos como agentes dispersores que cumplen un rol fundamental en la dispersión de especies vegetales y en la recuperación de ecosistemas amazónicos.

PT.Wulantika Utama is one of distributor in Palu who distribute products from factories to retailers. The purpose of this research are to maximize the distribution numbers of trucks and minimize the cost of distribution. Goal Programming is a method that can solve the problem with more than one purpose. Goal Programming model formulation in this study consists of 5 priority and 5 constraint functions. The fifth priority is the storage capacity, the number of trucks used for the distribution of goods to Donggala, Ampana, Poso, and cost targets are minimum distribution. Constraint function consists of inventory in the warehouse, the number of trucks and distribution costs. The results showed that the supply of goods by the warehouse capacity that can fulfiil the necessary distribution  product during a month amounted to 14.755 cartons. Optimal distribution for each destination, in Donggala are 8 trucks with a capacity of 250 cartons, Poso are 20 trucks with a capacity of 300 cartons and Ampana are 14 trucks with a capacity of 500 cartons. This result can save distribution costs of Rp.90.993.009 from the previous distribution costs  of Rp. 282 602.689.

Palu city is one of the cities with unstable changes of natural conditions. The natural conditions such as the frequency of rainy day, temperature and humidity which are always changeable bring bad impacts and will cause of diseases especially dengue hemorrhagic fever (DBD). Therefore, it needs an action to recognise whether or not the natural condition factor influences the spread of DBD and determines what factors of the natural condition can influence the spread of DBD. This research applied quantile regression in the case of DBD in Palu city. Quantile regression is an analysis technique regarding to the functional relationship between one dependent variable with one or more independent variables which can provide accurate and stable results even though there will be outliers. Based on the result of the research, it is obtained that the natural condition factor affected the spread of DBD. This is because from 3 natural conditions only 11 significant or influential quantiles on the tested data, the quantiles are 0,30; 0,35; 0,40; 0,45; 0,50; 0,55; 0,60; 0,65; 0,70; 0,75 and 0,80. Meanwhile the most influential factor of natural conditions in spreading DBD is  the frequency of rainy day because it has positive which means that 1 progress of percentage will increase the quantity of DBD case.

Let 𝐺 = (𝑉, 𝐸) be a simple graph. An edge covering of 𝐺 is a family of subgraphs 𝐻1 , … , 𝐻𝑘 such that each edge of 𝐸(𝐺) belongs to at least one of the subgraphs 𝐻𝑖 , 1 ≤ 𝑖 ≤ 𝑘. If every 𝐻𝑖 is isomorphic to a given graph 𝐻, then the graph 𝐺 admits an 𝐻 − covering. Let 𝐺 be a containing a covering 𝐻, and 𝑓 the bijectif function 𝑓: (𝑉 ∪ 𝐸) → {1,2,3, … , |𝑉| + |𝐸|} is said an 𝐻 −magic labeling of 𝐺 if for every subgraph 𝐻 ′ = (𝑉 ′ ,𝐸 ′ ) of 𝐺 isomorphic to 𝐻, is obtained that ∑ 𝑓(𝑉) + ∑ 𝑓(𝐸) 𝑒∈𝐸(𝐻′ 𝑣∈𝑉(𝐻 ) ′ ) is constant. 𝐺 is said to be 𝐻 −super magic if 𝑓(𝑉) = {1, 2, 3, … , |𝑉|}. In this case, the graph 𝐺 which can be labeled with 𝐻-magic is called the covering graph 𝐻 −magic. The sum of all vertex labels and all edge labels on the covering 𝐻 − super magic then obtained constant magic is denoted by ∑ 𝑓(𝐻). The duplication graph 2 of graph 𝐷2 (𝐺) is a graph obtained from two copies of graph 𝐺, called 𝐺 and 𝐺 ′ , with connecting each respectively vertex 𝑣 in 𝐺 with the vertexs immediate neighboring of 𝑣 ′ in 𝐺 ′ . The purpose of this study is to obtain a covering super magic labeling for of 𝐷2 (𝑃𝑚) on (𝐷2 (𝑃𝑛 )) for 𝑛 ≥ 4 and 3 ≤ 𝑚 ≤ 𝑛 − 1. In this paper, we have showed that duplication path graph (𝐷2 (𝑃𝑛 )) has 𝐷2 (𝑃𝑚) covering super magic labeling for 𝑛 ≥ 4 and 3 ≤ 𝑚 ≤ 𝑛 − 1 with constant magic for all covering is ∑ 𝑓(𝐷2 (𝑃𝑚) (𝑠) ) = ∑ 𝑓(𝐷2 (𝑃𝑚) (𝑠+1) )

Bananas is a kind of fruit that has many benefits and economic value. However, because it is perishable, an unappropriate post-harvest handling will decreasing the economic value. Many factors affect the ripening of bananas, one of it is ethylene gas. The ethylene gas that contained in the banana flows from the higher concentration to the lower one. The flow should be controlled in order to make it decaying properly. Temperature is a parameter that affects the flow of ethylene. This research offers storage temperature regulation such that the life time of banana could be extended. A mathematical model that represents the ethylene flow among the subpopulations is discussed. The population are devided into sub-population of unripe bananas, normal ripe bananas, ripe bananas wounds, and rotten bananas. The Stability of the model is evaluated in the critical point by Jacobian matrix and the Routh Hurwitz Criteria. The control is design by minimizing the temperature parameters using the Pontryagin Minimum Principle. Simulation is ilustrated in four cases, the firts case is no bananas wound initially, second case is no bananas rot initially, third case is no ripened normal bananas initially, and the fourth case is the bananas ripe initially exiting. The simulations shows that before controling the temperature, in the amount of 120 bananas of firts case, the proces is condcuted in sixteen days, ten days for the second case, nine days for the third case, and eight days for the fourth case. After controling the temperature, for some amount of bananas of firts case, the proces is conduted in seventeen days, eleven days for the second case, ten days for the third case, and nine days for the fourth case.
