Published: July 2020

Abstract. This article presents a Dielectric database of organic Arctic soils (DDOAS). The DDOAS was created based on dielectric measurements of seven samples of organic-rich soils collected in various parts of the Arctic tundra: Yamal and Taimyr Peninsula, Samoilovsky Island (the Russian Federation), and Northern Slope of Alaska (U.S.). The organic matter content (by weight) of the soil samples presented varied from 35 % to 90 %. The refractive index (RI) and normalized attenuation coefficient (NAC) were measured under laboratory conditions by the coaxial waveguide method in the frequency range from ~ 10 MHz to ~ 16 GHz, while the moisture content changed from air-dry to field capacity and the temperature from −40 °C to +25 °C. The total number of measured values of the RI and NAC contained in the database is more than 1.5 million values. The created database can serve not only as a source of experimental data for the development of new soil dielectric models for the Arctic tundra but also as a source of training data for artificial intelligence satellite algorithms of soil moisture retrievals based on neural networks. DDOAS is presented as Excel files. The files of DDOAS are available on http://doi.org/10.5281/zenodo.3819912.

Published: July 2020

Abstract. The grounding zone of Whillans Ice Stream, West Antarctica, exhibits an abrupt transition in basal properties from the grounded ice to the ocean cavity over distances of less than 0.5–1 km. Active source seismic methods reveal the grounded portion of the ice stream is underlain by a relatively stiff substrate (relatively high shear wave velocities) compared to the deformable till found elsewhere beneath the ice stream. Several kilometers upstream of the grounding zone, layers of subglacial water are detected, as are regions that appear to be water layers less than the thickness resolvable by our technique. The presence of stiff subglacial sediment and thin water layers upstream of the grounding zone supports previous studies that have proposed the dewatering of sediment within the grounding zone and the possibility that ocean water is pumped into the subglacial system and upstream. The setting enables calibration of our methodology using returns from the floating ice shelf. This allows a comparison of different techniques used to estimate the sizes of the seismic sources. We find a strong correlation (coefficient of determination = 0.45) between our calibrated method and a commonly used amplitude ratio method, but our results also highlight the incomplete knowledge of other factors affecting the amplitude of seismic sources and reflections in the cryosphere.

Authors: Kar Anindya , Bhugra Dinesh , Mukherjee Shuvankar , Mondal Agnibho , Kumar Aaditya Suresh
Published: July 2020

Introduction: The global revolution of online social media and connectivity had a tremendous effect on sexual behavior in both developed and developing countries. This global change is influencing the societal structure and existing social principles. Moreover, it has a significant impact on the epidemiology of different infectious diseases, especially HIV.Discussion: India is one of the most diverse democratic countries that has undergone a social-cultural transition in the last decade. However, having the second-highest HIV infection rate in the world, India does not have any other new prevention tools in their national HIV prevention strategy. Pre-Exposure Prophylaxis (PrEP), a boon of HIV prevention widely used in different countries, is still not implemented in India. The concept of “Digital India” by the Government of India is giving wide access of internet to the people of India. Furthermore, people are exposed to social media, and that is impacting their sex seeking behavior. Interestingly, recent legal changes in India promotes sex positivity. It also calls for introspection on existing HIV preventive strategies.Conclusion: Given the current scenario of PrEP and other existing preventive measurements of HIV, further research is needed to determine the acceptance and efficacy of PrEP and improve engagement in care for individuals in India. Various international studies recommend effective implication of PrEP to reduce the rate and economic burden of HIV infection.

Authors: Platero Méndez R. Lucas , López Sáez Miguel Ángel
Published: July 2020

La pandemia de COVID-19 y las medidas adoptadas por el gobierno en España han tenido un impacto negativo en la infancia y juventud. Pro ha sido particularmente pernicioso para la infancia y juventud que tienen sexualidades e identidades de género no normativas, que de entrada sabemos ya viven unas condiciones de vida que están atravesadas por un mayor estrés y ansiedad que el resto debido a la falta de apoyos, tienen un mayor riesgo de suicidio y de consumo de sustancias. Una vulnerabilidad que es más pronunciada en quienes son jóvenes trans o personas no binarias. En reciente estudio que elaboramos sobre los impactos psicosociales de la pandemia del COVID-19 en personas LGTBQA+ en España, con datos recogidos entre el 9 de marzo y el 9 de mayo de 2020, se obtuvieron 94 cuestionarios de menores de 18 años. El análisis preliminar sobre estos datos arroja información relevantes sobre el efecto específico de la pandemia en la adolescencia con sexualidades e identidades de género no normativas.

Crianças e Distanciamento Social: breve análise de uma proposta pública para a Educação Infantil
Authors: De la revista Secretaría , Ribeiro Pollyanna Rosa
Published: July 2020

O presente trabalho indica alguns efeitos do distanciamento que as crianças pequenas matriculadas na rede pública de ensino estão suscetíveis no período de pandemia da doença COVID-19, com destaque à ruptura com as vivências e experiências promovidas nos Centros Municipais de Educação Infantil. O texto tem como finalidade apresentar e analisar as propostas pedagógicas que a Rede Municipal de Ensino de Goiânia, uma capital do centro-oeste brasileiro, traz à comunidade educacional da Educação Infantil por meio da plataforma aberta “Conexão Escola”. Para a construção deste texto foi necessária a abordagem de cada uma das sugestões apresentadas às famílias das crianças de 0 a 5 anos e 11 meses, que se propõe indicar ações a serem desenvolvidas com as crianças em âmbito doméstico. Percebe-se que as orientações destinadas às famílias respeitam parcialmente os modos de aprendizagem das crianças, defendendo as trocas sociais e as brincadeiras, contudo falta subsídio material e simbólico que chegue diretamente à criança, pois o uso de telas é de certa forma incentivado. Não se presentifica uma oferta material que estabeleça laço mnêmico ou vínculo com o contexto institucional e a realidade singular da criança.

The role of European physicians in the assessment of work disability: A comparative study
Authors: E. de Wind Annette , Donceel Peter , M. Dekkers-Sánchez Patricia , Godderis Lode
Published: July 2020

Aims: The aim of this study was to describe and compare the role and tasks of the physicians involved in the medical assessment which takes place at the transition from short-term to long-term work disability in the 14 European countries as well as the required knowledge, skills and competencies to carry out those tasks. Methods: We organized a multi-stage research model consisting of written information, an expert group meeting and data analysis (from 14 European countries), using both Donabedian's triad model and the CanMEDS framework. Results: Most of the resources and information the physician has available at the start of the assessment, concurs. Some of the resources are only in some countries specific for insurance medical assessments. The process steps are more or less comparable in the participating countries as is the output. Set against the CanMEDS framework the physician, while carrying out the long-term work disability assessment fulfils all the roles to a greater or lesser extent. Conclusion: Most of the input and structure in this survey concur and although there are differences, so do process and output. Despite the difference in degree to which the CanMEDS roles are fulfilled, depending on the national legislation and operationalization of the assessment, we can conclude that physicians in all countries need to have all seven CanMEDS roles when carrying out the assessment of long-term work disability. Physicians require specific knowledge, skills and competencies, in addition to general medical knowledge, skills and competencies.

O PROGRESSO CIENTÍFICO EM A VIAGEM AO CENTRO DA TERRA (1864), DE JÚLIO VERNE
Authors: Dos Santos Rodrigues Heitor
Published: July 2020

No século XIX, houve a popularização de leitura de romances, que traziam críticas sobre o presente e um possível futuro distópico que a civilização europeia estaria caminhando. Houvera, no entanto, debates em torno da postura de Júlio Verne diante do progresso científico, se estaria ele vangloriando ou alertando sobre os perigos que a tecnologia poderia trazer a humanidade. É nesse sentido que se busca mostrar este debate em torno da obra Viagem ao Centro da Terra (1864), com base na explicação de que Verne sempre tivera postura crítica ao progresso científico e ao contexto político francês, como claro na sua obra Paris no século XX, mas que a sua editora censurou com o medo do fracasso comercial, obrigando Verne a assumir uma postura oposta em a Viagem ao Centro da Terra. Mesmo assim, ainda encontram-se elementos e simbolismos que levam as críticas ao futuro com base da situação do presente.
Os impactos do progresso nos mundos natural e social na obra Os Trabalhadores do Mar, de Victor Hugo.
Authors: Kochani Frizzo Matheus
Published: July 2020

No presente artigo, analisamos o romance Os Trabalhadores do Mar, de Victor Hugo, e a forma como este gira em torno da relação entre o Homem e a Natureza, ou, em um sentido mais prático, entre o progresso técnico-científico e as forças naturais. Durante a obra, se nota um embate notável entre os dois, quase como condição inevitável de suas existências. Essa discussão, porém, não foi uma simples invenção de Victor Hugo; ela não apenas é impactada pela biografia do autor como também se articula ao contexto em que ele viveu, marcado pela industrialização e urbanização europeia, assim como pelos consequências que trouxeram.
Site Specific Nutrient Management for Maize on Ultisols Lampung
Authors: Murni Andarias Makka , Pasuquin Julie Mae , Witt Christian
Published: July 2020

Site Specific Nutrient Management  for Maize on Ultisols Lampung (A M Murni, JM Pasuquin, and C Witt): Lampung is the third major maize producing province in Indonesia after East Java and Central Java. In Lampung maize is cultivated mainly in upland areas with ultisols and only some cultivated on paddy field as a secondary crop in the dry season. The average maize yield in Lampung is still 3.4 Mg ha-1 bellow yield potential of 7-10 Mg ha-1. To increase the productivity of maize through site-specific nutrient management (SSNM), on-farm trials were conducted in five locations in Lampung i.e. four locations in Central Lampung District (Sidowaras, Binjai Ngagung, Watu Agung and Balai Rejo) and one location in South Lampung District (Trimulyo, Tegineneng Sub District) during the 2004/2005, 2005/2006 and 2006/2007 rainy seasons. The experimental setup followed a standard protocol at all sites and included nutrient omission plots (PK, NK, NP) to estimate indigenous nutrient supplies, an NPK plot to measure yield response to fertilizer application, and a farmers’ fertilizer practice (FFP) plot in each farmer’s field. An SSNM treatment plot was included in the second and third seasons. Each of the above treatments was paralleled by a plot with improved crop management practice (ICM), i.e. higher planting density, addition of lime, and addition of magnesium. Results showed that yield response to fertilizer N, P and K application in these sites were: N = 2.3-4.1 Mg ha-1; P = 0.6-2.0 Mg ha-1; K = 0.3-2.4 Mg ha-1. Attainable yield in the three seasons on average ranged from 7.6 Mg ha-1 to 10.6 Mg ha-1. Yield in the SSNM treatment (with or without ICM) was significantly higher than the FFP indicating great opportunities for farmers to increase productivity and profitability with improved nutrient and crop management.

Microclimate of Developed Peatland of The Mega Rice Project in Central Kalimantan (A Jaya,T Inoue, SH Limin, U Darung and IS Banuwa): In Indonesia peatland covers an area of 16 to 27 Mha and this ecosystem is vitally linked to environmental and conservation issues, as well as its economic value for human survival. These peatlands are, however, the subject of various land use pressures, including forestry, agriculture, energy and horticulture. A field study was carried out 6 years after the end of failed peatland development project shows that inappropriate and unsustainable forms of peatland management have resulted in degradation of the natural forest vegetation, draw-down of the peat water table, increase of peat surface and air temperatures and recurrent surface and ground fires. Implications of microclimate for possible restoration options.

A laboratory experiment was carried out at Cocoa Research Institute of Nigeria, Ibadan to evaluate the nutrientrelease pattern of neem fortified cocoa pod husk developed for use as organic fertilizer materials. Cocoa Pod Husk(CPH), Neem Leaf (NL), Neem Seed (NS), CPH + NL (90:10), CPH + NL (80:20), CPH + NS (90:10) and CPH +NS (80:20) were separately applied at the rate of 100 kg N ha-1 into 50 g soil placed in plastic cups. There were sixsampling periods (2, 4, 8, 12, 16, and 20 weeks) after treatment application. Soil N (Kjeldahl), P (Bray 1), K (1 NNH4OAc pH 7) and pH (soil:water ratio 1:2) were determined at each sampling period. The result showed that theorganic materials had significant effect in raising the pH of the soils compared to unamended soil. Neem fortifiedCPH significantly (P < 0.05) increased nitrogen release higher than control at 8, 12 and 16 weeks after application.Phosphorus release was significantly higher in soil treated with CPH, NL, NS and neem fortified CPH than thecontrol at 20 weeks after application. CPH and neem fortified CPH enhanced K release better than NL and NSapplied separately across the incubation periods. Neem leaf and seed powder with higher N content than CPH is aprecursor of N- release into the soil shortly after incorporation.[How to Cite: Ogunwole OM, GO Adeoye, O Fagbola and JS Ogeh. 2012.

Authors: AlJedaani Shafeah M.
Published: July 2020

Background: The novel coronavirus is a pandemic respiratory disease that spreads from person to person. As the outbreak continues to develop, several countries have taken measures to prevent the transmission of the disease. Some of these measures are quarantine and isolation. Nurses are on the front line of the health care system during the COVID-19 outbreak, and they may become overwhelmed by the numerous pressures, such as the risk of infection, inadequate supplies, workload, and frustration. The aim of this study is to identify nurses’ conditions in quarantine and isolation during the COVID-19 outbreak in Jeddah city.Methods: A cross-sectional descriptive design, a questionnaire was used for data collection.Results: About 60% of the participants were willing to continue working in quarantine and isolation. The main reasons they were willing to continue were a safe working environment (37.3%) and effective teamwork (31.8%), while the main reasons that made the participants unwilling to continue were the lack of rewards and incentives (28.3%), and an unsafe work environment (40.0%). Regarding the nurses’ assessment of quarantine and isolation conditions during the COVID-19, most participants confirmed that they often choose a positive element. This study found a significant difference according to the current place of work, which was positive on the side of the nurses who are working in quarantine.Conclusions: This study’s findings provide important recommendations related to the improvement of quarantine and isolation conditions, staff nurses’ conditions, and disease-outbreak-related readiness. It is hoped that these recommendations will contribute to enhance the current and future conditions of nurses in isolation and quarantine.
Effect of Autranellacongolensis on Lipid Profile of Rats’ Brain with Experimentally Induced Alzheimer’s Disease
Authors: Joël Ngoumen Ngassa Dany , Laure Ngondi Judith , Enyong Oben Julius
Published: July 2020

Lipids are essentials components of the brain. Changes in brain lipid composition affect the physical and functional properties of the neuronal cell membrane and have been implicated in the physiopathology of Alzheimer disease (AD). We evaluated in this study the effect of hydroethanolicbark extract of A. Congolensis on lipid profile of rats’ brain with experimentally induced AD. The experimental model consisted of female rats, which received orally for 8 consecutive weeks a single dose of 50 mg/Kg b.w./day of aluminum trichloride (AlCl3) (except control group) followed by distilled water (disease control group) or doses of the extract (150 or 300 mg/Kg b.w./day) or vitamin E (100 mg/Kg b.w./day) or galanthamine (2 mg/Kg b.w. /day). Brain cholesterol, phospholipids and plasmalogenlevels and fluidity were evaluated. Brain membranes ATPase activities, Ca2+, Mg2+and glucose levels were also assayed. Significant modifications of brain lipid composition and fluidity were observed in disease control group compared with control. In addition, Na+, K+-ATPase and Mg2+-ATPase activities significantly decreased, the level of intracellular Ca2+ increased, Mg2+ content decreased and brain glucose level was significantly higher. Standard drugs (vitamin E,galanthamine) showed a negative effect on brain lipid profile. The extract of 150 mg showed significant improvements of brain lipid profile and fluidity. It also indicated improved brain ATPase activities, ions and glucose brain homeostasis. The extract (150 mg/Kg b.w. dose) by maintaining the brain lipid composition may protect neuronal cell membraneand probably preventing the progression of AD.

Authors: Teixeira Divino Eterno , do Carmo Pereira Danielle , Diniz Nakamura Ana Paula , Brum Sarah Silva
Published: July 2020

Particles of flooded gum (Eucalyptus grandis) were bonded using three bio-based adhesives - anhydrous citric acid (CA), tannin-citric acid (TCA) and ricinoleic acid (RA) - from renewable sources and hot pressed to produce medium density particleboard (MDP). The bonding capacity of such adhesives and properties of the MDP were evaluated and compared to the requirements of seven grades of particleboards, according to the EN 312 (2010) standard. The RA did not create adhesion reaction with the wood particles. Adhesives formulated with CA and TCA presented capacity to bond eucalyptus particles into MDP confirmed by esterification reactions of the FTIRS analysis. MDP bonded with CA met requirements as high as grade P5 of the EN 312 (2010) standard for static modulus of elasticity (MOE) and internal bond (IB) and P2 for modulus of rupture (MOR). Panels bonded with TCA met requirements up to grade P3 for MOE, however, did not withstand water absorption.

The aim of this paper is to analyse and compare the official media reports published in the Republic of North (RN) Macedonia and some other South-Eastern European Countries, such as Croatia, Bosnia and Herzegovina, Serbia, and Bulgaria. According to the official results from Nielsen Arianna, IPSOS, and Alma Quattro, Macedonian furniture companies mainly allocate their media budget to television channels with an amount of EUR 4.786.710, which is 6.7 times lower than the amount allocated by Croatian furniture companies to the same media (EUR 32.223.506). The conclusion is that the media budget of Macedonian furniture companies is on a very low level, compared to selected South-Eastern European Countries, mainly because 74 % of the total number of furniture companies are micro enterprises with up to ten employees, which affects the media budget.

Teacher Decision-Making: Using Hypothetical Vignettes to Examine the Course Recommendation Process
Authors: Bernhardt Philip E
Published: July 2020

Academic tracking is common in American schools. While the impact of this practice on students is well documented, few studies closely examine the influence of teacher decision-making on students’ academic trajectories. This article discusses a study examining how teachers recommend students for high- and low-track academic classes. Specific attention is paid to data collected through participant analysis of hypothetical vignettes. This unique methodology was specifically designed to illuminate the dynamics shaping participants’ decision-making process. The key finding of this study is that participants experienced high levels of autonomy when making recommendations. This autonomy, however, did not emanate from recognition of their expertise or familiarity with students’ academic capabilities; rather, it resulted from ill-defined expectations, poor communication among teachers, and a lack of clear administrative policies. The analysis of data led to findings that are divided into five distinct but interrelated themes.
Using Focus Groups to Explore Sources of Self-Efficacy in Puerto Rican Preservice Teachers
Authors: Arcelay-Rojas Yitza A.
Published: July 2020

This article used focus groups to explore Puerto Rican preservice teachers' perceptions of sources of self-efficacy. The present study allowed, through a qualitative design, examination of the experiences of preservice teachers at the end of their student teaching practicum. The qualitative design and the use of the focus group technique provided insight into the main sources of their perceived self-efficacy through the self-assessment of their field experience. The beginning of the student teaching practicum provoked an intense process of emotions in which the preservice teachers needed support and guidance, particularly in aspects of planning, differentiation, and classroom management. The participants agreed that substantial feedback and guidance from cooperating teachers and university supervisors helped them being confident and increased their perceived self-efficacy by reducing the feelings of anxiety generated by the practicum.
Relevance of the IES/NSF Protocol to Identification of Evidence-Based Practices
Authors: Schirmer Barbara R. , Lockman Alison S. , Schirmer Todd N.
Published: July 2020

The Institute of Education Sciences (IES) and the National Science Foundation (NSF) issued common guidelines that provide a protocol by which the use of particular methodological designs in a line of research inquiry provides evidence for each successive step in the process of bringing any given instructional intervention into practice. Our purpose was to determine if research on two widely used literacy instruction approaches has been conducted at each methodological stage in the IES/NSF protocol and is relevant to identifying the approach as an evidence-based practice. We applied the IES/NSF pipeline-of-evidence guidelines to assess whether practices touted as having a research base for effectiveness have emerged from an accumulation of empirical evidence and identification of conceptual or theoretical frameworks. In mapping the six steps of the IES/NSF protocol onto the shared book reading and reciprocal teaching studies that had met What Works Clearinghouse evidence standards, we found that only reciprocal teaching involved research at each stage in the protocol and only reciprocal teaching was identified as an evidence-based instructional approach by the What Works Clearinghouse. Our results indicate that the IES/NSF pipeline-of-evidence protocol offers a productive approach to identifying evidence-based practices. The different trajectories of research on reciprocal teaching and shared book reading indicates that research at each stage in the protocol is important to the development of an instructional approach that ultimately demonstrates effectiveness in improving student learning outcomes.

Public Security and its Contexts
Authors: Hejduk Monika
Published: July 2020

The considerations presented in this article are based on several assumptions. First of all, the human environment and the
set of its elements are constantly changing. In the early periods of evolution and development of humanity, man lived in conditions
given by nature itself, no different than in natural conditions. However, even then, he was also exposed to threats, mainly natural,
including disasters. Secondly, with the passage of time and development there was a very large population increase, which caused
changes in quite primitive interpersonal and social relations. More and more organized communities, states began to emerge. With
this development, new threats also appeared. In addition to the natural threats, which were already natural by their very name, the
threats of a social nature began to emerge from the natural world around us, characterized by continuous and dynamic changes.
Thirdly, man, who wanted to effectively deal with the problems of the threats he faced, created safety systems. One of them is the
public security system. Fourthly, in today’s security environment there is a paradox that in practice these systems function, and
in theory there is no commonly accepted definition of public security. The circumstances outlined above determined the shape of this
article, the essence of which was to work out a compromise definition of public security based on the interpretation of this concept
by recognized authorities in the field of law, administration and security.

The concept of ’organisational culture’ can be described based on numerous approaches nowadays. This underlines the
fact that it is a significant issue within work and organisational psychology. However, the growing scope of organisational culture
and subculture types shows not only its significance, but also the appearance of its explanations in a wide spectrum. The extensive
research of organisational culture is related to the trend that there is a growing interest of organisational development and human
resource professionals in a deeper understanding of human behaviour in organisational settings, and the factors influencing it.
Organisational culture includes communication with clients (in the case of police, citizens) and the relating approach system. The
organisational culture cannot be considered basically “good” or “bad”. There are external and internal metrics and requirements
that reflect the state of a given organisation: they indicate the quality and quantity of value creation, the organisation’s acceptance
in its environment as well as its necessity in the society. The organisational culture is optimal if it serves the organisation’s tasks,
objectives, the fulfillment of its duties, an the maintenance of its expedience, as well as if it is supportive, creative and facilitating.
In an optimal organisational culture, the interests are enforced between the groups and people in the organisation in a peaceful
way, their work is effective and successful, all conditions are ensured, the staff is satisfied, and the organisation’s output is accepted,
recognised and required in its external environment. These organisations are acknowledged by the citizens and operate in accordance with their environments.
Borders of Digital Network Freedom
in Public Security Space

In the era of common access to freedom on the Internet, there are more and more controversies between advocates
of complete freedom and followers of the idea of limiting the usage of the global network’s resources. Should the Internet become
a space of unlimited freedom? Contrary to common belief, the answer to such a question is not that obvious, although intuitively one
would like to say yes. The Internet is basically an egalitarian tool of communication, a space of easy creation and transfer of content,
for which the only limit is technology and unlimited human imagination. Freedom seems to be not only an immanent, but even
a constitutive feature of the virtual space in which the Internet functions.
The Sense of Security of the Prison Service

Authors: POKLEK Robert
Published: July 2020

The concept of security is presented ambiguously depending on the scientific discipline. From a sociological point of view,
it means an objective state of no threat, integrally associated with subjective, emotional, psychological deprivation of space as safe,
otherwise referred to as a sense of security. In turn, in legal terms, it means all conditions and social institutions protecting the state
and citizens against phenomena dangerous to the legal order and to the life and health of citizens. From a psychological point
of view, the need for security is one of the fundamental needs of both individual individuals and entire social groups. Its satisfaction
provides a sense of confidence and a guarantee of lack or minimal risk threatening valuable values such as life, health, optimal
living standards and material goods. Everyone, to fulfil their tasks assigned to the social role, must feel safe. This is particularly
important in the case of people who, because of their profession, are supposed to protect security and other people, and such
a professional group is the Prison Service. The paper presents the results of the research carried out using the Uchanst’s Sense
of Security Questionnaire of the Confederation of National Defence among officers of the Prison Service who undergo vocational
training at the Central Training Centre of the Prison Service in Kalisz. The research has shown a optimal level of general sense
of security and factors which make up the sense of security syndrome, which is, the sense of closeness, stability and mutual trust.
The Role of Novel Composite of 2D Materials and Their Characterization, Properties, and Potential Applications in Different Fields

Published: July 2020

Thin layers or coating of transition metal dichalcogenides (TMDs) is a new class of two-dimensional (2D) inorganic materials with unique physical and chemical properties. This book chapter covers the recent research of thin film of 2D materials using various novel technologies to synthesize and grow monolayer 2D materials on different substrates in different fields based on the knowledge available in the literature. Thin film on substrate can be enhanced with the favorable properties. Therefore, selection of methods can play a key role in characterizing the coating. The novel coating processes on composite materials and their characterization, properties, and process and potential applications also have been discussed. The 2D materials that have been investigated created a thin film through different methods and were used to serve different biomedical purposes such as modifying drug release, improving energy efficiency and storing energy, catalysts, and so an.
Familial Syndromes of Primary Hyperparathyroidism
Authors: F. Simonds William
Published: July 2020

Regulation of serum calcium in vertebrates is maintained by the actions of the parathyroid glands working in concert with vitamin D and critical target tissues that include the renal tubules, the small intestine, and bone cells. The parathyroid glands release parathyroid hormone (PTH) into the systemic circulation as is required in order to maintain the serum calcium concentration within a narrow physiologic range. Excessive secretion of PTH from one or more abnormal parathyroid glands however results in primary hyperparathyroidism (HPT), a metabolic disease typically associated with abnormally elevated serum calcium. Although HPT is typically a sporadic disease, it can represent a manifestation of an inherited syndrome. Many sporadic parathyroid tumors result from inactivating mutations in tumor suppressor genes that were first discovered by the analysis of genomic DNA from patients with HPT as part of an inherited syndrome. Somatic and inherited alterations in DNA encoding proto-oncogenes can also cause parathyroid neoplasia. Two promising future approaches for the discovery of novel genes pertinent to parathyroid tumor development are the analysis of acquired genetic alterations in DNA isolated from parathyroid tumors and the investigation of familial HPT in kindreds lacking germline mutation in the known genes predisposing to HPT.
The Monte Carlo Techniques and the Complex Probability Paradigm
Authors: Abou Jaoude Abdo
Published: July 2020

The concept of mathematical probability was established in 1933 by Andrey Nikolaevich Kolmogorov by defining a system of five axioms. This system can be enhanced to encompass the imaginary numbers set after the addition of three novel axioms. As a result, any random experiment can be executed in the complex probabilities set C which is the sum of the real probabilities set R and the imaginary probabilities set M. We aim here to incorporate supplementary imaginary dimensions to the random experiment occurring in the “real” laboratory in R and therefore to compute all the probabilities in the sets R, M, and C. Accordingly, the probability in the whole set C=R+M is constantly equivalent to one independently of the distribution of the input random variable in R, and subsequently the output of the stochastic experiment in R can be determined absolutely in C. This is the consequence of the fact that the probability in C is computed after the subtraction of the chaotic factor from the degree of our knowledge of the nondeterministic experiment. We will apply this innovative paradigm to the well-known Monte Carlo techniques and to their random algorithms and procedures in a novel way.

Published: July 2020

Personal transportation is the act of transporting an individual by using a small, low-speed vehicle. It is a very hot research topic both in industry and academia. There are many different types of personal transportation vehicles, and wheelchairs are one of them. Autonomous driving is another very popular subject that is applicable to the personal transportation vehicles. Autonomous personal transportation vehicles are good examples of service robotics applications. In this study, conversion procedure of a conventional electric wheelchair into an autonomous personal transportation testbed and the application of some basic autonomous driving algorithms on the developed testbed are explained. In literature, there are several studies providing information on wheelchairs’ autonomy but not deep information about the conversion itself. In this paper, the conversion process is investigated in detail, under two main sections. The first part is by-wire conversion, which allows the wheelchair to be controlled via computer commands. The second part includes the studies on sensors, computational system, and human interface. After making such modifications on wheelchair, fundamental algorithms required for autonomy, such as mapping and localization, are implemented successfully. The results are promising for the usage of the developed system as a testbed for examining new autonomous algorithms and evaluating the performance of the perceptional/computational components.
The Borel-Cantelli Lemmas, and Their Relationship to Limit Superior and Limit Inferior of Sets (or, Can a Monkey Really Type Hamlet?)
Authors: P. Godbole Anant
Published: July 2020

The purpose of this chapter is to show that if a monkey types infinitely, Shakespeare’s Hamlet and any other works one may wish to add to the list will each be typed, not once, not twice, but infinitely often with a probability of 1. This dramatic fact is a simple consequence of the Borel-Cantelli lemma and will come as no surprise to anyone who has taken a graduate-level course in Probability. The proof of this result, however, is quite accessible to anyone who has but a rudimentary understanding of the concept of independence, together with the notion of limit superior and limit inferior of a sequence of sets.
A Service Management Metric with Origin in Plant Management
Authors: G. Batson Robert
Published: July 2020

The discipline of industrial engineering (IE) was originated in the US by Frederick W. Taylor, who first applied what he termed scientific management to machine shop management in the 1880s. IE expanded world-wide with applications of work measurement to all manner of manufacturing, then to services. A century later, as the Japanese practice of Total Productive Maintenance (TPM) became known in the US, the associated equipment management metric Overall Equipment Effectiveness (OEE) became well-known as a production metric that could be applied to individual manufacturing machines, production lines, and the overall production system. In this chapter, illustrations of the calculation of OEE are provided, along with modification of the three OEE inputs (availability, performance efficiency, and quality rate) to create a new service management metric Overall Service Effectiveness (OSE). Definitions and measures of service quality are reviewed. The first published application of OSE was to a city public transportation system, and is reviewed as a prototype. Essentially, applications of OSE require the industrial engineer to define service-specific measures of availability, processing rate, and quality at the management’s level of interest: work station, process, or system. The data collected to calculate OSE will also point toward actions that would improve OSE.
