Authors: Harkat Meriem , Alleg Safia , Chemam Rafik , Azzaza Sonia , Mokhtari Majda , Dhahri Essebti
Published: March 2021

Nanocrystalline and thermally stable hydroxyapatite (HA) powder with nominal composition of Ca10(PO4)6(OH)2 was prepared by wet chemical route from calcium hydroxide Ca(OH)6 and mono ammonium phosphate NH4H2PO4 as calcium and phosphate sources, respectively. The effect of calcination temperature on the structure, microstructure, molecular bonding, thermal behavior and morphology was investigated by X-ray diffraction patterns (XRD), Fourier Transform Infra-Red (FT-IR), Raman spectroscopy, thermogravimetry (TGA), differential thermal analysis (DTA) and scanning electron microscopy (SEM) coupled with energy dispersive X-ray spectroscopy (EDS) analysis. The XRD patterns of the as-prepared and calcined powders exhibit a single phase of hydroxyapatite. The crystallite size of as-prepared and calcined HA is in the range of 44-182 nm. FT-IR and Raman spectroscopy results are in good agreement with XRD ones. The EDS analysis reveals the presence of all elements. The thermal stability of the synthesized powders is evidenced by TGA/DTA scans which show a weight loss smaller than 2%.
Performance Prediction and Mix Ratio Optimization for Multielement Green High-Performance Fiber-Reinforced Cement Matrix Composite
Authors: Peng Zimao
Published: March 2021

Green high-performance fiber-reinforced cement (GHPFRC) matrix composite is prepared by mixing matrix composites like slurry, mortar, or concrete with reinforcing materials like metal or inorganic nonmetal fiber, synthetic fiber, or natural organic fiber by a certain method. This composite is more energy-efficient, ductile, low-carbon, economic, and environmentally friendly than ordinary concrete. However, the performance of GHPFRC matrix composite has not been fully studied. The existing research only deals with the seismic performance and fire resistance of the material, failing to systematically discuss the optimal mix ratio. To solve the problem, this paper presents an optimization strategy for multielement GHPFRC matrix composite, and carries out multiple tests on its basic mechanical performance, toughness, impact resistance, shrinkage cracking, dry shrinkage performance, and durability. The test data on various indices verify the superior performance of the prepared multielement GHPFRC matrix composite. Further, the optimal mix ratio of the material was determined as: 60% cement, 30% fly ash, and 10% silica ash, with the water-cement ratio of 0.4, water reducer dosage of 1.5%, and quartz sand dosage of 500g.

Authors: S Anzhel , E Kovachev , AB Tonchev , B Georgiev , G Yaneva , G Nenkova
Published: March 2021

Spina bifida is a neural tube defect that occurs in about 1 in 1,500 pregnancies. Open spinal defects are associated with paralysis, incontinence and hydrocephalus requiring postnatal shunting of the cerebrospinal fluid. Neural tube defects are preventable through preconceptional folic acid supplementation. Occasionally, the diagnosis is made during routine anomaly scan at 18-20 weeks of gestation, as the earliest signs of the anomaly can be seen at the end of first trimester. The information provided by ultrasound plays a crucial role in patient counseling and pregnancy management. The authors report a case of prenatal diagnosis of spina bifida aperta with focus on detailed ultrasound presentation and difficulties in consulting in relation to the prognosis for the newborns.

Published: March 2021

The main objective of the research is identifying the effectiveness of artificial intelligence in the business sphere of Kazakhstan. The urgency of this problem is due to the fact that the Kazakhstani market for artificial intelligence is at the initial stage of development. The main obstacle to the introduction of artificial intelligence is the unpreparedness of managers of small and medium-sized businesses for the application of artificial intelligence technologies and, of course, the high cost of their implementation. In the study, we proceeded from the key thesis that business in Kazakhstan is striving for digital transformation. We set a goal to determine the attitude and degree of readiness of Kazakhstani business to the implementation and practical application of artificial intelligence, to describe the cases of using artificial intelligence by Kazakhstani business, to identify the main questions that arise in business at this stage, to study the legal aspects of using artificial intelligence in business and to present the big picture compliance / inconsistency of the existing legal framework with the goals and objectives of the development of artificial intelligence, provide recommendations for eliminatinge xisting barriers and stimulating businesses to implement the technology. Within the framework of this study, the concept of artificial intelligence is defined in its broadest sense - as a set of technologies for processing various types of data and information, in particular those capable of interpreting such data, extracting knowledge and using it to achieve certain goals.

Published: March 2021

Based on a systematic analysis, the article examines the current state of the activities of the internal affairs bodies in combating domestic violence, determines the influence of decriminalization and subsequent administrative torture of beatings on crime in the domestic sphere, as well as the place and role of the district authorized police in countering family crime household sphere. The study becomes the basis for the conclusion that the decrease in the number of crimes on household grounds was the result of decriminalization of minor crimes (beatings) and their transfer to the number of administrative offenses, which, in turn, firstly turned into effective administrative and legal household crime prevention means, including in the sphere of family-domestic relations. Secondly, this led to a decrease in the latency of offenses committed in the sphere of family-domestic relations, as well as an increase in the preventive potential laid down in the norms of administrative-tort legislation. In addition, the author comes to the conclusion that it is necessary to administratively torture family quarrels (violence) as a condition for increasing the preventive potential of administrative and tort legislation in counteracting offenses committed in the field of family and domestic relations

Authors: USUL Eren , HALICI Ali , HOKE Mehmet
Published: March 2021

Aim: Acute carbon monoxide (CO) poisoning is a potentially mortal, though preventable, condition. Mild poisoning presents with non-specific symptoms, such as fatigue, headache, nausea and vomiting, whereas severe exposure to CO can result in loss of consciousness, coma, and death. The aim of this study was to investigate the utility of lactate and carboxyhemoglobin (COHb) levels in the clinical presentation and treatment of patients with acute CO poisoning.
Material and Methods: Data were obtained from the hospital information system and patient files with ICD-10 code “T58: Toxic effects of CO”. The blood parameters and vital signs of patients at admission, causes of poisoning, time to hospital, and Glasgow coma scores during admission were recorded. Within related and relevant complications of CO intoxication and data concerning treatment plans and hospitalization status were recorded.
Results: A statistically significant difference was found between COHb and lactate levels of patients who did and did not develop neurological and cardiac complications (p<0.001). Moreover, a statistically significant difference was found in COHb and lactate levels among patients who did or did not receive hyperbaric oxygen therapy, and who were hospitalized or not (p<0.001). As looking for biochemical profile, significant correlations was found between COHb and pH, base excess, and bicarbonate and lactate levels.
Conclusion: This study shows that COHb and lactate levels at admission to the emergency department are significant for prognosis, follow-up, and treatment of patients with CO poisoning. Elevated lactate and COHb levels may also found to be associated with neurological and cardiac complications.

Problemy konceptualizacji i operacjonalizacji pojęcia sukcesu zawodowego
Authors: Pilch Piotr
Published: March 2021

Celem rozdziału jest ukazanie metodologicznej złożoności badania pojęcia sukcesu zawodowego w polskim kontekście kulturowym. Złożoność ta przejawia się zarówno w procesie konceptualizacji badanego pojęcia, jak i jego operacjonalizacji. Przyczyny jej mają wieloraki charakter i zostaną ujęte w porządku chronologicznym, społeczno-kulturowym i metodologicznym. Dualizm sukcesu zawodowego wyrażony w opozycji między procesem jego osiągania, a rezultatem tego procesu oraz jego obiektywno-subiektywnej naturze, skutkuje koniecznością konstruowania takich metod pomiaru, które uwzględniają jego specyficzny i wielowymiarowy charakter. Celem analiz będzie udowodnienie zmiany społecznych kryteriów sukcesu zawodowego z tych konstruowanych i potwierdzanych społecznie na rzecz zindywidualizowanych wymiarów oceny. Dotychczasowe stosunkowo proste miary obiektywnego sukcesu zawodowego są uzupełniane przez miary uwzględniające perspektywę jednostki (jej system wartości, cele, potrzeby) czy przyjmowane punkty odniesienia (znaczący inni) w perspektywie komparatystycznej. Procesy takie można zaobserwować śledząc rozwój zagranicznych narzędzi badawczych. Logiczną konsekwencją powyższego jest wypracowanie rekomendacji metodologicznych na bazie zakotwiczonych lokalnie rozważań terminologicznych i zagranicznych doświadczeń badawczych, co do konstrukcji adekwatnych technik pomiaru sukcesu zawodowego na gruncie polskim.
Rozwiązywanie problemów i podejmowanie decyzji zespołowych – metody i narzędzia
Authors: Mikosik Piotr
Published: March 2021

Celem rozdziału jest przedstawienie metodyki zespołowego rozwiązywania problemów. Skuteczne podejmowanie decyzji rozpoczyna się od zidentyfikowania natury problemu, by na tej podstawie dobrać sposób pracy nad przygotowaniem rozwiązań. Proste i powtarzalne wymagają rutynowych działań podejmowanych przez menedżera indywidualnie. Tymczasem złożone, nietypowe kwestie są efektywniej rozwiązywane z udziałem zespołu pracowników przy wykorzystaniu profesjonalnej metodyki podejmowania decyzji. Specjalistyczna metodyka jest tym bardziej konieczna, jeżeli członkowie zespołu pozostają ze sobą w konflikcie i ze względu na to nie można od nich oczekiwać skłonności do kompromisów, wsłuchiwania się w argumenty innych i chęci budowania porozumienia. Podstawą skuteczności przeprowadzenia zespołu przez proces rozwiązywania problemów jest prostota procesu i wykorzystywanych metod. Z tego powodu autor rekomenduje model podejmowania decyzji składający się z następujących etapów: identyfikacja problemu, diagnoza sytuacji, poszukiwanie rozwiązań, ocena rozwiązań, planowanie i wdrożenie. W opracowaniu przedstawiono wybrane metody wykorzystywane w poszczególnych etapach procesu podejmowania decyzji.

Conclusion

After using of diacritics, the new modified Arabic version can be used confidently as a valid and reliable measure of family needs.
A Reflection on the Concept of Youth as Identity in Literary Journals in Italy a Century Ago
Authors: Striano Apollonia
Published: March 2021

This contribution aims to develop some observations on the concept of identity with specific reference to a particular historical moment, the period just before the First World War, in a particular context, Italy, in which young intellectuals compared their ideas and debated with each other in periodicals. Through the collation of two manifestos, published in two journals in distant geographical areas, and of the experiences of the two publishing houses, we have tried to verify the dogma itself of the writing and the communicative action, perceived as an indispensable stimulus to engagement, to the aesthetic composition of another world and to the tacit evocation of the miracle of a new beauty.

Mudar o mundo através do poder. Notas críticas às interpretações de Holloway sobre a transição
Authors: Lazagna Angela
Published: March 2021

John Holloway em seu livro, Mudar o mundo sem tomar o poder, apresenta-nos suareflexão sobre a atual estratégia de superação da sociedade capitalista: “... para destruiro capitalismo sem recair na sua lógica”, faz-se necessária a construção de “...uma sociedadede relações de não-poder...”. Mas a destruição do capitalismo não pode decorrer,segundo o autor, da conquista do poder do Estado, já que ele representa um tipo de“poder-sobre”. Por conseguinte, uma transformação social baseada no “não-poder” eno “anti-poder” não poderia ocorrer através do Estado. Daí o título de seu livro.

A concepção de homem em Marx e Engels e o programa socialista do século XXI
Authors: Bittar Marisa , Ferreira Junior Amarilio
Published: March 2021

Vivemos a passagem do século XX para o XXI em meio à crise provocada pelo fimdo “socialismo real”, que desencadeou uma onda de ataques aos “velhos esquemasinterpretativos” valorizando o fragmentário, o efêmero e o imaginário, bem como propagandoa “morte do marxismo”. Presenciamos o reduzido valor dos “produtos” marxistasno “mercado de bens simbólicos”, fartamente alimentado pelos “novos paradigmas”.Ao mesmo tempo, em nossa prática acadêmica como professores universitários,ouvimos críticas que revelavam desconhecimento da obra de Marx e Engels,entre elas, por exemplo, a de que o marxismo seria anti-humanista por haver substituídoo homem por forças produtivas e relações de produção. Para enfrentar essas questões teóricas, aprofundamos o estudo do marxismo epassamos a oferecer um curso anual possibilitando a leitura e o debate entre estudantesda pós-graduação, para os quais, na quase totalidade, foi a primeira oportunidadede ler um texto original dos dois pensadores.O trabalho que ora apresentamos é resultado dessas reflexões e com ele desejamosdiscutir o conceito de homem em Marx e Engels demonstrando exatamente ocontrário daquelas críticas. Iniciamos com a indagação: neste começo de século emque se fala tanto da redescoberta do valor do indivíduo, há algo mais atual do que olugar que Marx reservou para o indivíduo na sua concepção de emancipação humana? Foi com Marx que aprendemos que o capitalismo é um sistema no qual o processode produção domina os homens e não os homens o processo. O humanismo deMarx em O Capital não é um simples protesto moral: ele rasga o véu mítico da reificação,decifra o “hieróglifo” do valor, apreende a realidade social (humana) oculta pelaopacidade do mercado. Nessa obra em que dissecou o processo de degradação físicae intelectual dos trabalhadores, o capítulo sobre o fetichismo é a chave para a compreensãodo seu humanismo. Mas será que os “novos críticos” a leram?

A Qualitative Study of Female Academics: The Case Associate Senior Lecturers
Authors: Lozano-Cabezas Inés , Iglesias-Martínez Marcos Jesús
Published: March 2021

The equality of relations in the place of work is one of the most important keys for development teacher and professional at Universities. This paper reports a qualitative study of female academics’ personal experiences of professional life, especially with regard to and problems of their integration in professional networks as departments and research teams. The results show that, although mentoring and learning networks are now an established part of the range of professional development opportunities for academic staff in general, these do not apply in the same way to female academics. Moreover, whilst female academics do not experience institutional discrimination, they are dissatisfied with opportunities for participation and career advancement. The results can contribute to a better design of the campus politics.
The Hidden Variables Theory
Authors: Fried Israel
Published: March 2021

The book presents a new concept on several physics topics. The initial values are non-relativistic quantities of subatomic particles which the values obtained in experiments are actually their relativistic reflection. The subjects in the book are presented in such order that each new topic is based on the development of its predecessor that explains where it stems from. The book presents methods of analyzing traditional physics concepts to extract hidden embedded information that reveals new variables which are combined with those known. The new formulas yield results that match experiments accurately. It presents discoveries as: The electric charge of subatomic particle results directly from its OAM (Orbital Angular Momentum). OAM Offset exhibits neutral state. The electron mass is a magnitude that expresses quantitatively the square of its magnetic flux quantum, hence this mass in Hydrogen Wave Function yields solutions that their squared values represent the flow pattern of magnetic flux surrounding electrons at energy levels, contrary to probability density describing odds of locating electron in atom. In calculation of hydrogen's wave function the electron and proton constitute one entity. Hence zero OAM at ground state determined by computational and experimental means is due to OAM offset of electron and proton rotation in opposite directions at center of mass. The proton, neutron and all baryons consist of three energy levels on which the quarks are orbiting. The third energy level of 80.5Gev plays a major role in the weak force while it is filled by charged mesons that are emitted thru W boson while acquiring the level's energy. The OAM of the orbiting quarks are third or two thirds of the reduced Planck constant. The proton missing spin is resolved by the OAM of quarks. The Electron is bound state composition of a negative Pion and an Electron's neutrino. The theory predicts a neutral boson of 160Gev (Accompanied by W+ boson from 240Gev decaying particle).
Defect Depth Estimation in Infrared Thermography with Deep Learning

Infrared thermography has already been proven to be a significant method in non-destructive evaluation since it gives information with immediacy, rapidity, and low cost. However, the thorniest issue for the wider application of IRT is quantification. In this work, we proposed a specific depth quantifying technique by employing the Gated Recurrent Units (GRU) in composite material samples via pulsed thermography (PT). Finite Element Method (FEM) modeling provides the economic examination of the response pulsed thermography. In this work, Carbon Fiber Reinforced Polymer (CFRP) specimens embedded with flat bottom holes are stimulated by a FEM modeling (COMSOL) with precisely controlled depth and geometrics of the defects. The GRU model automatically quantified the depth of defects presented in the stimulated CFRP material. The proposed method evaluated the accuracy and performance of synthetic CFRP data from FEM for defect depth predictions.
Economic Sustainability of Small-Scale Hydroelectric Plants on National Scale – The Italian Case Study
Authors: Raimondi Anita , Bettoni Filippo , Bianchi Alberto , Becciu Gianfranco
Published: March 2021

The feasibility of hydroelectric plants depends on a variety of factors: water resource regime, geo-graphical, geological and environmental context, available technology, construction cost and eco-nomic value of produced energy. Choices about the building or renewal of hydroelectric plants should be based on the forecast of the future trend of these factors at least during the project life of the system. Focusing on the economic value of the produced energy this paper examines its influ-ence on the feasibility of hydroelectric plants. Analysis, referred to Italian case, were based on three different phases: i) the economic sustainability of small-scale hydroelectric plants under a minimum price guaranteed to the hydroelectric operator; ii) the estimate of the incentives to reach the thresholds of "acceptability" and "bankability" of the investment; iii) the analysis of results ob-tained in the previous phases using a model of the evolution of the electricity price in the period 2014-2100.
Elastic-Perfectly Plastic Contact of Rough Surfaces: An Incremental Equivalent Circular Model
Authors: WANG GF
Published: March 2021

In this paper, an incremental eqivalent contact model is developed for elastic-perfectly plastic solids with rough surfaces. The contact of rough surface is modeled by the accumulation of circular contacts with varying radius, which is estimated from the geometrical contact area and the number of contact patches. For three typical rough surfaces with various mechanical properties, the present model gives accurate predictions of the load-area relation, which are verified by direct finite element simulations. An approximately linear load-area relation is observed for elastic-plastic contact up to a large contact fraction of 15%, and the influence of yield stress is addressed.
Physical Laws shape up HOX Gene Collinearity
Authors: Papageorgiou Spyros
Published: March 2021

Hox gene collinearity (HGC) is a multiscalar property of many animal phyla particularly important in embryogenesis. It relates entities and events occurring in Hox clusters inside the chromosome DNA and in embryonic tissues. These two entities differ in linear size by more than four orders of magnitude. HGC is observed as spatial collinearity (SC) where the Hox genes are located in the order (Hox1, Hox2, Hox3 …) along the 3’ to 5’ direction of DNA in the genome and a corresponding sequence of ontogenetic units (E1, E2, E3, …) located along the Anterior – Posterior axis of the embyo. Expression of Hox1 occurs in E1. Hox2 in E2, Hox3 in E3… Besides SC, a temporal collinearity (TC) has been also observed in many vertebrates. According to TC first is Hox1 expressed in E1, later is Hox2 expressed in E2, followed by Hox3 in E3,… Lately doubt has been raised whether TC really exists. A biophysical model (BM) was formulated and tested during the last twenty years. According to BM, physical forces are created which pull the Hox genes one after the other driving them to a transcription factory domain where they are transcribed. The existing experiments support this BM description. Symmetry is a physical-mathematical property of Matter that was explored in depth by Noether who formulated a ground-breaking theory that applies to all sizes of Matter. This theory applied to Biology can explain the origin of HGC as applied not only to animals developing along the A/P axis but also to animals with circular symmetry.

In the last decade, readily available electronic devices have created unprecedented opportunities for teens to access a wide variety of information and media – both positive and negative – on the internet. Despite the increasing number of initiatives taking place worldwide intended to assess and mitigate the online risks encountered by children and adolescents, there is still a need for a better understanding of how adolescents use the internet and what consequences they may face. We conducted a cross sectional online survey of a convenience sample of 733 8th and 9th grade students in Utah. The survey contained eight questions regarding students’ exposure to three types of online risk scenarios: content risk, contact risk, and commercial risk. Independent variables included students’ online behaviors, use of social media and private messaging apps, and adult supervision of online activities. Logistic and negative binomial regression models indicated that female gender, social media use, and chatting with strangers were associated with exposure to multiple unsafe online scenarios. Our results provide critical information to practitioners involved in the development of educational initiatives by building a profile of potentially risky online behaviors and allow them to tailor their initiatives to meet the needs of more vulnerable populations.
