This research study is endeavoured to discover the factors that will lead the consumers’ staying intention at green hotels, especially of those who practise the Shariah Law (Islamic green hotels). Nowadays, there has been an increase in public concern regarding environmental issues. Consumers are more environmentally aware than they were in past decades. Hotels are among the largest contributors of energy consumers in the tertiary building sector, which contribute to some negative impacts to the earth at the same time. The most obvious negative impact of hotels on environment are solid waste generation and disposal. Therefore, numerous consumers are supportive of green consumption and consider it as a successful method to protect the environment. In Islamic green hotels, Muslim-friendly amenities have also been provided to protect Muslims travellers’ welfare that is by providing them a comfortable prayer room, the Holy Quran and Islamic practices booklets, prayer mats and a direction of Qibla. A set of questionnaires was distributed to 256 respondents among the community and tourists in Kuching, Sarawak. The dependent variable in this study was consumers’ staying intention while the independent variables were green image, green satisfaction, Muslim amenities and lifestyle and price fairness. This research study also made use of the Statistical Package for Social Science (SPSS) software to analyse the result based on the questionnaires distributed to the respondents. Based on the result of analysis, it is shown that the green image and green satisfaction were found of having a positive significant that influence the consumers’ staying intention at the Islamic green hotels. Besides that, Muslim amenities and lifestyle was also found to have a positive significant impact that influences the consumers’ staying intention. Most Muslims were likely to choose a destination with Islamic practice to fulfil their daily duties. However, green price fairness did not significantly influence the consumers’ staying intention. This is because if green image, green satisfaction, Muslim amenities, and lifestyle meet the requirements of the Muslim tourists, they would not be affected by the price. As a matter of fact, price may be the least factor of consideration by the tourists in choosing a hotel to stay.

E-commerce has transcended the traditional way of shopping into a new and more efficient way of purchasing. Through this approach, businesses are conducted through the internet in which activities such as information searching, information sharing, products and services purchasing are performed. There are many reasons why online purchasing has become one of the most preferred channels for customers to purchase goods or services. This study is conducted to examine crucial factors related to customers' satisfaction in online shopping and specifically looking at four factors: information quality, service quality, security/privacy and website design and their relationship with customers' satisfaction in online purchasing. 320 questionnaires were distributed through purposive sampling techniques to students from a public university in Malaysia. The findings revealed that website design and information quality were the most impactful factors that influence customer’s online purchasing. These findings are useful for online retailers and marketers to understand consumers' behaviour when purchasing online, thus enabling them to develop more effective marketing strategies. For future research, this study suggests that the population of the study should be expanded and other types of variables should be included such as mediating and moderating variables to obtain more accurate and precise findings. It is also suggested that the research could be conducted using random samplings so that the findings can be generalised.
The Role of Maqasid Shariah and Islamic Religiosity in Tourism Perspectives
Authors: Nurafiqah Mohamad Musa  , Nur Murniza Mohd Zaidi
Published: March 2021

Conventional tourism had opened a “window” for Islamic tourism to operationalize which at present is expanded throughout the world. As the Muslim population is rising rapidly, Muslim consumer market should be critically concerned by tourism businesses to satisfy the needs and wants of the consumers. This paper attempts to explain the concept of Islamic tourism in the context of maqasid shariah – protection of religion, protection of intellect, protection of life, protection of wealth and protection of offspring; discusses the role of Islamic religiosity in shaping tourists’ behaviour, as well as tourism industry’s role in applying Islamic tourism according to maqasid shariah, from the tourism industry’s perspective and tourists’ perspective. To date, there is still lack of knowledge and related literature review on the implementation of maqasid shariah in the concept of tourism industry. The ultimate goals of shariah are vital as the platform in the development of Islamic tourism as well as Islamic religiosity among Muslim consumers because it resembles the value of Islamic concept in tourism perspectives.
Firms’ Specific Determinants of Capital Structure: An Analysis into Construction Firms in Malaysia and Singapore
Authors: Siti Zulaikha Binti Upilin  , Hapsah S.Mohammad
Published: March 2021

The study aims to examine the firm-specific factors such as firm size, profitability and asset tangibility in the capital structure decisions (leverage) on a sample of twenty construction firms in Malaysia and Singapore from 2009 to 2018, with 200 observations. The sample firms are chosen based on convenience sampling technique and the availability of the data. Prior studies documented inconclusive findings on the determinants of capital structure and different industries tend to reveal different patterns of relationship. In addition, the empirical evidence on comparative analysis between construction firms in Malaysia and Singapore is lacking. Hence, the objective of this study is to extend the prior work by investigating the impact of the determinants on capital structure on the construction firms in Malaysia and Singapore. The study uses panel data analysis to test the effectivity of trade-off, pecking order and agency cost theories of capital structure. The empirical findings reveal positive and significant association between firm size and capital structure for Singapore firms. Meanwhile, profitability and asset tangibility correlate negatively with capital structure. As for Malaysian firms, the three determinants exhibit insignificant association with the capital structure. The study only examines 10 construction firms in Malaysia and 10 construction firms in Singapore, therefore, the small sample size becomes the limitation of the study. Nevertheless, the findings of this study may contribute to the body of knowledge on the importance of some firm-specific determinants such as profitability, tangible assets, and firm size in order to determine the optimal level of capital structure for firms in these countries.

Split equality variational inequality problems for pseudomonotone mappings in Banach spaces
Authors: Boikanyo Oganeditse A. , Zegeye Habtu
Published: March 2021

"A new algorithm for approximating solutions of the split equality variational inequality problems (SEVIP) for pseudomonotone mappings in the setting of Banach spaces is introduced. Strong convergence of the sequence generated by the proposed algorithm to a solution of the SEVIP is then derived without assuming the Lipschitz
continuity of the underlying mappings and without prior knowledge of operator norms of the bounded linear operators involved. In addition, we provide several applications of our method and provide a numerical example to illustrate the convergence of the proposed algorithm. Our results improve, consolidate and complement several results reported in the literature."

An optimization problem for continuous submodular functions
Authors: Csirmaz Laszlo
Published: March 2021

"Real continuous submodular functions, as a generalization of the
corresponding discrete notion to the continuous domain, gained considerable
attention recently. The analog notion for entropy functions requires additional
properties: a real function defined on the non-negative orthant of $\R^n$ is
entropy-like (EL) if it is submodular, takes zero at zero, non-decreasing,
and has the Diminishing Returns property.
Motivated by problems concerning the Shannon complexity of multipartite
secret sharing, a special case of the following general optimization problem
is considered: find the minimal cost of those EL functions which satisfy certain
constraints.
In our special case the cost of an EL function is the maximal value of the
$n$ partial derivatives at zero. Another possibility could be the supremum
of the function range. The constraints are specified by a smooth bounded
surface $S$ cutting off a downward closed subset. An EL function is feasible
if at the internal points of $S$ the left and right partial derivatives of
the function differ by at least one.
A general lower bound for the minimal cost is given in terms of the normals
of the surface $S$. The bound is tight when $S$ is linear. In the
two-dimensional case the same bound is tight for convex or concave $S$. It
is shown that the optimal EL function is not necessarily unique. The paper
concludes with several open problems."

Introduction. Blood microcirculation and its microrheologic properties are impaired in cardiovascular diseases. Microrheologic properties are characterized by the red blood cells (RBC) ability to aggregate and disaggregate. Therefore, the correlation studies between RBC aggregation and microcirculation disorders in pathologies are of interest for the development of theoretical concepts related to blood flow and for clinical practice.

Aim. To analyze the correlation between capillary blood flow parameters measured in vivo and microrheologic blood parameters measured in vitro in patients suffering arterial hypertension (AH) and coronary heart disease (CHD).

Materials and methods. We studied 3 groups of people: patients suffering AH, patients suffering AH+CHD and healthy donors. The characteristic aggregation time and aggregation index were measured in vitro by laser aggregometry. Analysis of capillary blood velocity (CBV) and assessment of the presence and absence of RBC aggregates in the nail bed capillaries were performed in vivo using vital digital capillaroscopy (VDC).

Results. RBC aggregation for groups of patients suffering AH and AH+CHD was increased compared to the control group. Thus, in these patients groups, the characteristic aggregation time significantly decreases by an average of (38±13) %. Comparison of the results obtained using in vitro and in vivo methods showed the aggregation index for individuals with high CBV was significantly lower than for individuals with low CBV. The tendency is that the number of aggregates in the capillaries increases with a decrease in CBV.

Conclusion. RBC aggregation is increased in groups of patients suffering AH and AH+CHD compared to the control group. The correlation between parameters measured in vitro and in vivo is evident for patients divided into subgroups according to parameters measured using the VDC. The obtained results allow us to conclude that the used methods are applicable in clinical practice.

Objective. Measurement and comparison of the aggregation and disaggregation forces of individual erythrocytes during the formation or breakdown of a paired aggregate in vitro in the blood of patients with type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM) using the optical tweezers method. Materials and methods. A total of 50 people were included in the study. Of these, 10 people with T1DM (aged 28±15.8), 26 people with T2DM (aged 66±13). The control group consisted of 14 apparently healthy volunteers (46±21 years old). Measurements of the forces of pair interaction of erythrocytes in a diluted suspension were carried out in vitro by the method of dual-channel optical tweezers. The force of aggregation of erythrocytes FA (pN) and the force of disaggregation FD (pN) were measured and their ratio FD/FA was calculated.

Results. The erythrocyte aggregation forces in the T1DM group did not differ significantly from the control group. However, the forces of disaggregation in the T1DM group were significantly lower than in the control group (p<0,05). The ratio of the forces of disaggregation to the forces of aggregation was lower in the T1DM group compared to the control group (p<0.005). In T2DM group, erythrocyte aggregation forces were higher compared to the control group (p<0.005). At the same time, the ratios of the forces of disaggregation to the forces of aggregation in T1DM group and T2DM group did not differ.

Conclusion. Both T1DM group and T2DM group are characterized by hyperaggregation of erythrocytes. However, given the data obtained, it can be assumed that the mechanisms of such hyperaggregation are different.
Las mujeres de la elite en el Reino Antiguo, ¿un grupo social incapaz de actuar?
Authors:   University of Geneva (Suiza), Betbeze Romane
Published: March 2021

During the Old Kingdom, we can observe numerous instances of female tomb owners, who constituted the center of the iconographic and textual program of tombs and individual chapels. Thus, these women from the elite may have had some social power related to their status, as well as an autonomous capacity of ostentation, both elements that were linked to male qualities. Although various scenes were directly integrated, without any change, in those tombs where the major figure was a feminine one, some adaptations were sometimes needed, proving that gender specificities influenced the type of activity depicted. Indeed, the aim of this paper will be to analyze these gender qualities on the basis of the iconography, and especially through the “marsh scenes”, as well as to question the dichotomy between action/masculine and inaction/ feminine.
Cleómenes de Náucratis: realidad, fuentes e historiografía
Authors:   Universitat Autònoma de Barcelona (España), Mendoza Marc
Published: March 2021

"Cleomenes of Naucratis was the first “Great man” in Hellenistic Egypt. In the sources, he appears as an ambitious, rogue governor, who may even have crossed the line of sacrilege in relation to the Egyptian sanctuaries. This paper presents a thorough analysis of the sources about Cleomenes’ activities, evaluating their objectivity. In this way, it will be possible to assess how this data could be biased due to certain political purposes (e.g. to legitimise Ptolemy’s usurpation) or prejudices, like those that the Athenians could have had after his ethically controvertible management of the famines of the 320s BCE. It is only when keeping these facts in mind that it is possible to have a well-balanced image of his role in the Egyptian satrapy during the first stages of the Hellenistic dominion of the country"
Of Creator and Creation: Some Observations on the Cosmogonical Conceptions in the Stela of Suty and Hor (BM EA826), Papyrus Leiden I 350, and the Hymn to Ptah of the “Great Harris Papyrus” (BM EA9999, 44)
Authors:   International Association of Egyptologists (Egipto), Borges Pires Guilherme
Published: March 2021

The present paper constitutes a brief preliminary approach to the cosmogonical conceptions suggested by three New Kingdom texts: the stela of Suty and Hor (BM EA826), Papyrus Leiden I 350 and the Hymn to Ptah of the “Great Harris Papyrus” (BM EA9999, 44). Taking into account and discussing the phraseological repertoire attested in these sources, an attempt is made to understand two fundamental aspects: who is the Creator and what does he create. Thus, the first part deals with the identity of the Creator, namely, his names, attributes, and core features. The second considers the different beings and cosmic elements brought into existence by the demiurgic action. Throughout the paper, some commentaries are provided on the different methods performed by the Creator to succeed in his task, in the context of the New Kingdom religion as a whole

In 1923, Reginald Engelbach published the report of the works carried out from 1913 to 1914 in the excavation of the tombs of Haraga. In one of the structures of C Cemetery, Engelbach found a set of objects that he called fisherman’s equipment, comprising the remains of fishing nets, floats, net weights and wooden stakes. In this article, which is a summary of one of the chapters of the author’s doctoral thesis, she analyses the fishing instruments from Haraga and exposes the methods of capture in which stakes are used. The text is concluded with a proposal of the fishing gears and catching methods that could have been used in el-Fayum from the Middle Kingdom to the New Kingdom by means of a diachronic perspective and the ichthyological species possibly caught. In order to accomplish this goal, the author uses the archaeological record and other sources such as iconographic, documentary and ethnographic ones

The paper considers the optical properties and structure of thin films of titanium dioxide formed by the glancing angle deposition method. It was show that this method allows the formation of coatings having a significantly lower refractive index than that of the initial material. Thus, the experimentally obtained value of the refractive index of thin films of titanium dioxide was ~1.2, which is almost two times less than that of a polycrystalline material. This allows you to use this method to produce the coatings with a variable refractive index using only one material, changing the geometry of the deposition process only.

Ways of disseminating(Verbreitungsmedien) information through different media have rapidly changed owing to technological progress, especially in the field of information and communication technologies. Reflecting the changes in terms of conditions of technological progress, communication methods, and abilities have also changed. On the Internet, contents with different expressions of difficulty are mixed even though they have almost the same contents. A user who intends to search for new things or unknown things may get confused and spend a lot of time in selecting contents that are understandable for them because there are large amounts of similar contents with different difficulties. Herein, The characteristics of relevant simplified corpora are critical for everybody. In this research, we propose a method to compare two types of documents with different difficulty, and select a characteristic related to simple of expression from various characteristics related to text. In our proposed method, thousands of text characteristics are compressed and converted by Non-negative Matrix Factorization(NMF), and a basis for characterizing the simplified document is selected. The proposed method combines the characteristics of the most conducted research using the characteristics of 32 types and 2,196 dimensions. We evaluated the text characteristics in the NMF Base of the results using a classifier. As a result of applying the proposed method to two kinds of environment white papers, it became clear that an effective basis can be selected. In Addtionally, We showed estimate of the causation relationships, Optimization of the parameter. Furthermore, We showed flexibility to other media.
Fast and Parallel Ranking-based Clustering for Heterogeneous Graphs
Authors: Yamazaki Kotaro , Sato Tomoki , Shiokawa Hiroaki , Kitagawa Hiroyuki
Published: March 2021

The demands for graph data analysis methods are increasing. RankClus is a framework to extract clusters by integrating clustering and ranking on heterogeneous graphs; it enhances the clustering results by alternately updates the results of clustering and ranking for the better understanding of the clusters. However, RankClus is computationally expensive if a graph is large since it needs to iterate both clustering and ranking for all nodes. In this paper, to address this problem, we propose a novel fast RankClus algorithm for heterogeneous graphs. To speed up the entire procedure of RankClus, our proposed algorithm reduces the computational cost of the ranking process in each iteration. Our proposal measures how each node affects the clustering result; if it is not significant, we prune the node. Furthermore, we also present a parallel algorithm by extending our proposed algorithm by fully exploiting a modern manycore CPU. As a result, our extensive evaluations clarified that our fast and parallel algorithms drastically cut off the computation time of the original algorithm RancClus.
A Collaborative Filtering based Approach to Classify Movie Genres using User Ratings
Authors: Ghawi Raji , Pfeffer Jurgen
Published: March 2021

In this paper, we present an approach for classifying movie genres based on user-ratings. Our approach is based on collaborative filtering (CF), a common technique used in recommendation systems, where the similarity between movies based on user-ratings, is used to predict the genres of movies. The results of conducted experiments show that our genres classification approach outperforms many existing approaches, by achieving an F1-score of 0.70, and a hit-rate of 94\%. We also construct a multilayer network of movies, with genres as layers. We apply agglomerative clustering on the layers of this network to obtain a comprehensible taxonomy of genres which groups together similar genres using the similarity of their movies in terms of user preferences.
Depression status in relation to dental caries and salivary C-Reactive Protein among 17 years old secondary school female in Baghdad City/Iraq.
Authors: Al-Bazaz Noor  A , MH Radhi Nada  J
Published: March 2021

Background: Depression is a state of low mood and aversion to activity, it can affect a person's thoughts, behavior and sense of well-being. It can affect oral health and lead to an increased risk of dental caries. Dental caries is the most common oral infectious diseases that stresses the immune system and causes changes in cellular and molecular components of peripheral blood and C-Reactive Protein is one of these components, considered a key biomarker of inflammation. This study was conducted to assess the effect of depression status on dental caries among 17 years old secondary school female students in relation to salivary C-Reactive Protein. Materials and Methods: A cross sectional study was carried and the whole sample composed of 500 female students selected from First Alrasafa Directorate schools in Baghdad/ Iraq. Consent form was achieved from the ethical approval committee in College of Dentistry/University of Baghdad. All students were subjected to Children Depression Inventory questionnaire by Kovacs in 2011. Dental caries was registered according to Manji et al. 1989, Decay (1-4) Missing-Filled surface index. Subsamples were selected from high and low grade of depression to analyze C-Reactive Protein. Results: The percentage of occurrence of depression was 100%. The mean value of caries experience and severity were found to be higher among female students with high depression grade in comparison with low depression grade. The mean value for C-Reactive Protein was higher in high depression grade. There is a diversity in the results of caries experience with C-Reactive Protein. The percentage of depression occurrence was 100% which means a high degree of depression, and this could be due to the life difficulties, tension and economic issues that all lead to mental problems. The severity of dental caries increased as a result of stress and anxiety that may cause poor dental health. Psychological factors interact through complex pathophysiological and behavioral mechanisms that may cause elevated C-Reactive Protein. Conclusion: Depression has a negative impact on a personâ€™s oral health including dental caries. Elevated C-Reactive Protein levels have been associated with psychological depression.

Background: Due to the variations in tooth anatomy and size among different populations, this study aimed to compare the mesiodistal width of primary second molars in Iraqi children with the mesiodistal width of stainless-steel crowns from different companies. Materials and Methods: This cross-sectional study was conducted on 220 intact maxillary and mandibular primary second molars selected from boys and girlsâ€™ Iraqi children aged 8-9 years collected from different primary schools in Baghdad city. The mesiodistal dimensions of the selected teeth and the available maxillary and mandibular stainless-steel crowns from three different companies were measured by using a 3-D scanner, and then the whole measurements were calculated using 3 shape Ortho-analyzer software program. Results: Data were analyzed statistically via SPSS V 26 software and the results showed that thereâ€™s non-significant difference between the MD measurements of second primary molars between right and left sides, and high significant difference were recorded with higher mean values for boys than girls. When comparing the same mesiodistal measurement between molars with that of stainless-steel crowns, only limited sizes of stainless steel crowns were found to be fitted to the molars of Iraqi children. Conclusion: more studies need to be applied using other stainless steel crown companies to find the relation in the mesiodistal measurement of Iraqi populations.

İz elementler ile ilgili olarak, karayosunu örnekleri mikrodalgada çözünürleştirme işlemi sonrasında indüktif eşleşmiş plazma-kütle spektrometresi (ICP-MS) ile analiz edilmiştir. Yosun örneklerinde iz elementler için bulunan konsantrasyon sıralaması Zn>Pb>Cu>Cr>Ni>As>Cd şeklindedir. PAH’ların ve metallerin hem kendi içlerinde hem de birbirleriyle olan muhtemel ilişkileri Pearson korelasyon analizi ile incelenmiş ve bazı değişkenler arasında istatistiksel olarak anlamlı ilişkilerin olduğu bulunmuştur. PAH’lar ve iz elementler için örnekleme noktalarına göre birikim yoğunluk haritaları oluşturulmuş ve söz konusu kirleticilerin termik santrallere yakın noktalarda daha yüksek seviyelerde olduğu gözlenmiştir.
Getting Closer to Communities: The Warmth of Community Well-being in the Local Government Act 2002

Published: March 2021

The reintroduction of community well-being as a purpose, into the Local Government Act 2002, has created the opportunity for the Councils to engage with their communities in a more holistic way. Although the Councils are consulting within their jurisdictions, this is currently more focused on the core services delivered or assets managed by them. With the community well-being framework in place, the Councils will be able to monitor the developments within their communities from a social, economic, environmental, and cultural perspective. It will enable them to participate on the ground level and to raise the volume with the central government agencies on what matters most for their communities.

The enabling factor for this conversation to happen is sitting with the extensiveness of community engagement from the Council side. Through these engagements, the Councils will be able to identify and prioritise the outcomes which their communities’ value. These outcomes will be impacting on the Council business as to what and how they will deliver the core services.

In this thesis, we will be looking into the history and role of community well-being in the Local Government Act 2002, and its evolution into the Local Government (Community Well-being) Amendment Act 2019. Along with it, we intend to identify a framework and a set of indicators on community well-being which are common across the local government sector.

This research will primarily help the staff members of the Councils to grasp the dynamics of community well-being and to incorporate it in their various strategic plans and reports. Secondly, it will help the community organisations and contractors to work more closely with the Councils and see how they can have a more positive impact on their communities. Thirdly, this piece will seek to align the well-being work of the local government sector with the work currently undergoing at the central government level; specifically, the Living Standards Framework (LSF) at The Treasury and Indicators Aotearoa New Zealand (IANZ) at Statistics New Zealand.

The purpose of this research is to examine the influence of service quality (SQ), Price (P) and Restaurant Environment (RE) on customer loyalty (LOY), via the mediating role of customer satisfaction (SAT) in the context of the restaurant industry in the capital city of Pakistan (Islamabad). Five hundred questionnaires were distributed at various restaurants in a different location at Islamabad, and 385 were returned. Multiple Regression Analysis was used to test hypothesis relationships. The outcome of this research shows that SQ, Pand RE have a positive association with the SAT. In contrast, customer satisfaction also leads to customer loyalty. Moreover, customer satisfaction significantly mediates the association among SQ, P, RE, and customer loyalty. The restaurant operators need to consider that good quality of service, fairness in price, pleasant and attractive restaurant the environment can increase customer satisfaction, which often contributes to customer loyalty.

This research study investigates the role of board gender diversity in mitigating the risk of corporate expropriation of listed companies in Pakistan. For this purpose, data from 2009 to 2019 has been collected for 223 firms randomly selected from 24 non-financial sectors. The current study used panel data analysis techniques i.e. random vs fixed-effect regression models were estimated for testing the relationship of board gender diversity and corporate expropriations. The results of the panel data analysis showed that Hausman test results support the random effect models for the analysis of the data. The results of the random effect models showed that board gender diversity has a negative significant effect on the dividend ratios and director loans, which are used as a proxy for corporate expropriations. Moreover, external audit quality, growth, and leverage are also found to hurt corporate expropriations. However, managerial ownership, net profit margin, and size variables are found to have a positive effect on corporate expropriations. The results of the study will be helpful for the corporate managers and policy makers regarding the corporate governance and provide a deep insight in to the role of the gender in managing and aligning the benefits of the outsider shareholders by reducing the corporate expropriations of controlling large shareholders.  The study is novel in its nature as being the first study that has been conducted in the context of Pakistan and has studied the role of gender in managing corporate expropriations.
Study of the albumin structure in human plasma using small-angle scattering of synchrotron radiation

Albumin is a nanoscale protein packed in a specific way into a polypeptide chain. Albumin maintains the osmotic pressure of the blood and protein reserve of the body, and provides an important transport function. We present the results of studying the structure of plasma albumin using a small-angle scattering of synchrotron radiation, one of the most effective analytical methods for analysis of the nanoscale structures. Moreover, the method provides studying the structures of liquid biological objects in a natural solution. It is shown that protein globules have the form of ellipsoids with semi axes 8, 8, and 3 nm and are formed by three domains consisting of α-spirals. The domains differ in the distance between ordered α-spirals. Albumin can be in the form of separate globules, dimers and oligomers surrounded by hydration membranes. Protein molecules in the studied plasma are arranged chaotically. The results obtained can be used to develop a method for assessing the quality of plasma based on the determination of the quantitative content of individual globules. Data on the protein structure are also valuable for the therapeutic applications of albumin.

Austenitic stainless steels are widely used in nuclear and thermal power engineering due to their high mechanical, corrosion and technological properties. We present the results of studying the effect of deformation martensite on the corrosion resistance of chromium-nickel steels of the austenitic class. Samples of heat exchange tubes of steam generators, tube bends, plates (constituents of steam turbines), safety valves used in NPP equipment were studied. The tests were carried out using metallographic, X-ray diffraction, atomic emission and atomic absorption spectral analyses. Electron microscopy was used to determine the content of the ferrite phase. It is shown that irregular dark gray spots located along a line parallel to the sample axis contain iron oxides. The appearance of such defects observed only on the outer surface of the products is attributed to the technology of their manufacture. It is also shown that severe plastic deformation which occurs during production or operation leads to formation of the deformation martensite which is subject to corrosion at this the corrosion cracking is accompanied by stress. The absence of δ-ferrite in the metal of samples is also revealed. The deformation martensite formed during operation of the product at the point of contact with a harder material leads to appearance of a large number of microcracks, which develop according to the fatigue mechanism under cyclic loading. The results obtained can be used to assess the probability of the formation of deformation martensite in chromium-nickel austenitic steels.
Evaluation of the brittleness and viscosity of metals upon tensile testing
Authors: Bugrov Yu. V. , Hlybov A. A. , Chegurov M. K.
Published: March 2021

The indicators of the brittleness and viscosity of metals calculated from their mechanical properties are considered with allowance for the stress state proceeding from the results of tensile testing of cylindrical smooth and notched samples of perlite 16KhSN, martensitic-aging (maraging) 03Kh11N10M2T, and austenitic 10Kh11N23T3MR steels. Tests were carried out on a UEM-10TM tensile strength testing machine, deformation diagrams developed on a scale of ~50:1 at a deformation rate of 5 mm/min. The sample size before and after testing were measured using a micrometer and an ISA-2 comparator with an accuracy of ±10–3 mm. Pendulum impact bending tests were carried out on a MK15 with the same cylindrical notched samples used to plot the plasticity and viscosity diagrams depending on the Bridgman stress state stiffness index. The new indicators of the brittleness λ = εk/η and viscosity η = (Sk/σb) – 1 (where εk = ln(1/(1 – ψk)) is the true limit plasticity) are proposed proceeding from the testing data. The special feature of the brittleness index λ is growth of the index with increase in the metal strength, e.g., due to pre-deformation or strengthening heat treatment procedures. However, a decrease in the groove radius on the samples, i.e., an increase in the Bridgman stress state stiffness, has almost no effect on the brittleness value λ, but is accompanied by a correlation decrease in the values of the viscosity indices η and the ultimate ductility εk of steels. The curves of the temperature dependences of the mechanical properties of steels 16KhSN and 03Kh11N10M2T show that anomalies in the brittleness indices λ observed at elevated test temperatures can be attributed to the structural transformations like increase in the grain size of 16KhSN steel or in the amount of the residual austenite in 03Kh11N10M2T steel due to reverse martensitic transformation. In this case, the temperature dependences of the viscosity η and brittleness λindicators change in the opposite way.
