Experimental Characterization of a Functionally Graded Composite Using Recycled Steel Fiber
Authors: Yagoub Mohamed , Mellas Mekki , Benchabane Adel , Zatar Abdallah
Published: June 2022

Many industries have recently focused on cost-effective materials with good mechanical properties. Steel fiber reinforced cementitious composites have proven their mechanical performance in industrial and structural components. The concept of recycled fiber-reinforced FGM is used as an alternative construction material, which can be one of the proposed cost-effective solutions. To achieve these objectives, an experimental program has been developed. A cementitious composite based on local materials was strengthened in two designs; one strengthened over the entire cross-section and the other strengthened only in the tensile zone. We also substituted a functional gradient material reinforced with recycled fibers considering the following volume fractions: 0, 0.5, 1, and 1.5%. This paper investigates the feasibility of using recycled fibers from industrial waste from steel wool manufacturing as reinforcement. We also characterized their mechanical properties using ultrasonic pulse velocity, compressive strength, flexural tensile strength, and shear strength. The results show that the corrugated recycled fibers are the ideal choice to increase the mechanical performance of the reinforced composite, including the improvement of flexural and shear behaviors. Therefore, the investigated FGC could be a valuable tool to optimize the design process in various structural applications and make the production of mechanically and environmentally economical composites possible. Doi: 10.28991/CEJ-2022-08-05-03 Full Text: PDF

Authors: Ngo Si-Huy , Nguyen Ngoc-Tan , Nguyen Xuan-Hien
Published: June 2022

As a large amount of steel is produced for the industrialization and modernization of Vietnam, a correspondingly large quantity of steel slag is also released annually. Besides, the demand for mortar is increasing due to urbanization, especially for the high-strength and durability mortar used for important constructions and structures in aggressive environmental areas. This study aims to carry out further research into high-strength mortars incorporating ground granulated blast furnace slag (GGBFS). The control mixture was designed with a water-to-binder ratio of 0.2, and the amount of silica fume used was equal to 25% of the total binder amount by mass. Four other mixtures were designed using GGBFS to substitute for 15, 30, 45, and 60% of cement by mass. The engineering properties of fresh and hardened mortars were comprehensively investigated, especially the durability properties. The microstructure of these mortars was also examined using scanning electron microscopy. Test results show that replacing 15 or 30% of cement with GGBFS yields an improvement in mortar's strength and durability properties. All the mortars in this study show excellent qualities with high strength, low water absorption, and high resistance to chloride attack. Moreover, the presence of GGBFS reduces the shrinkage of mortar caused by the drying process. Doi: 10.28991/CEJ-2022-08-05-07 Full Text: PDF
Impact of External Environmental Factors on Construction Firms' Performance, Mediated By Institutional Pressures
Authors: Fehan Hassan , Aigbogun Osaro
Published: June 2022

While the mainstream of construction management research has paid attention to the causes of poor performance in construction projects, there is a dearth of empirical research that considers the influence of external environment and institutional pressures in the debate. The objective of this research was to examine the impact of external environmental factors and institutional pressures on the performance outcomes of construction firms. The role of institutional pressures as a mediator in that relationship was also evaluated. Using a self-administered questionnaire, primary data was collected from 250 executives working in construction firms. This was then analysed using partial least squares structural equation modelling. The results demonstrated that both external environmental factors and institutional pressures have an impact on the performance of construction firms. In light of the institutional theory, the findings addressed a genuine research gap, as institutional pressures were discovered to mediate the relationship between external environmental factors and construction firm performance outcomes. This study contributes to the current debate about the causes of poor performance in construction firms by assisting managers in recognizing the impact of the aforementioned factors on a firm's performance. Doi: 10.28991/CEJ-2022-08-05-09 Full Text: PDF

Published: June 2022

News is one of the most significant means that provides information to the public regarding the events that may affect them in modern societies. Especially in situations such as climate change, where its effects are felt globally and each individual must comply with the recommended measures, the news broadcast is of importance. The news based on the right sources and edited by expert journalists will contribute to the development of responsibility in this vital issue that will determine the future of the world. While preparing the news on this subject, many different actors such as scientists, artists and campaigns created by governmental institutions or civil initiatives, as well as journalists, determine how the climate crisis is expressed in the daily discourses. Therefore, the discourse constructed by the news frames also shapes the perceptions of the masses about the climate crisis. The framing of climate crisis news in terms of problems, solutions and levels of responsibility is of great importance both for the determination of individual and social reactions and for the realization of social responsibility and action. In this context, this study aims at understanding the content and production style of climate crisis journalism in Turkey in terms of the messages conveyed. The research focuses on mass media, which widely broadcast for the general audience in Turkey, and the news on the climate crisis in the online news sites will be analyzed in the context of news framing theory. Due to the fact that the online news is open to interaction and can be easily accessed by a wide range of audience, the news samples to be analyzed were determined by scanning online news sites.

The issue of an imbalance in demand and supply of red chili and fluctuating red chili prices have initiated the Ministry of Economy, especially the Deputy for Food and Agribusiness Coordination, to implement a pilot of closed loop partnership model. The partnership is a form of cooperation that is beneficial for parties who have agreed, usually, partnerships are formed and carried out between parties who have agreed and have been bound by an agreement, SOP, or contract. The purpose of this study is there is an impact on the income and farm efficiency of chili farmers in partnership with non-partner farmers in Garut and Sukabumi Regency?. The data analysis carried out includes qualitative data analysis methods that are described descriptively in the analysis of farm performance. The quantitative analysis method used farm income analysis, income and cost comparison analysis (R/C Ratio), and different test analyses to determine the level of efficiency of chili farming commodities by partner and non-partner farmers in Garut and Sukabumi Regency. The results of this study indicate that the profit of closed loop chili farming is more profitable (IDR89.889.654/ha/season with R/C=2,06). Although the productivity and quality of chili produced by closed loop farmers (8,691 tons/ha) is relatively similar to non-closed loop farmers (8,491 tons/ha), it can be seen that the price received by closed loop farmers is higher (IDR15.457/kg) compared to the price received by non-closed loop farmers (IDR11.998/kg). The closed loop partnership model can be considered to have a positive impact on the income and efficiency of chili farming.

Demand for garlic in Indonesia tends to increase, but only a little (< 5 percent) of it was met by national production. This study aims to analyze the competitiveness of Indonesian garlic and identify its determinants. Data used on garlic farming was obtained from the Agricultural Census 2013-Central Bureau of Statistics (BPS), consisting of 121 sample farmers in West Nusa Tenggara province and 98 farmers in Central Java province. The Policy Analysis Matrix (PAM) method was used to measure comparative and competitive advantages which were grouped according to the technical efficiency of production. Efficiency is estimated by the Data Envelopment Analysis (DEA) method. The results showed that garlic has a comparative and competitive advantage in only 55 percent of the total sample. The comparative and competitive advantages of garlic were significantly determined by the technical efficiency of production. Further analysis showed that the competitiveness of Indonesian garlic was sensitive to changes in productivity and output prices. Productivity is the most decisive factor in the competitiveness of Indonesian garlic. Government policies related to input prices and output prices caused farmers to pay lower input prices and accepted output prices higher than their social prices. From this study can be concluded that in general Indonesian garlic was not competitive being produced domestically. Garlic can be produced domestically as an import substitution if it is produced with high productivity and efficiency. It is recommended to improve the technical efficiency of production by utilizing the potential land and technology production optimally.

The success of IPB student's study can be seen from the achievement index obtained at the end of each semester. Meanwhile, the success rate of one's study is generally influenced by two factors, internal factors and external factors. Internal factors consist of intelligence (intellectual), physical, attitudes, interests, talents, and motivations, while external factors consist of family circumstances, school conditions, and the community environment. Therefore, this study uses the analysis method of classification and regression trees (CART) to find out what factors influenced the success of the Student Council (OSIS) university students.

        Regression tree it is one of the methods of classification and regression trees (CART) to perform classification analysis on both categorical and continuous response variables. Continuous response variables will produce a regression tree or hierarchical data group that starts at the root and ends with a relatively homogeneous small group. The response variable used in this study is the Achievement Index of first semester students. The results obtained from the analysis showed that there are several different variables in each class in influencing the success of the student council (OSIS) university students, but if we look further, there are two variables that are the same in influencing the success of the student council (OSIS) university students, which are variables from high school province and student study programs.

                This study uses secondary data from 493 IPB students track the chairman of the student council of the year 2018-2020 which is still active until now. Furthermore, the analysis of the regression tree is performed against four different models, for each of the force and the overall force by adjusting the variables available. The formation of tree regression performed 10 repetitions and the results of regression trees is taken from a tree which has the approximate value of the smallest risk. Then, the final results obtained from the analysis showed that there are several different variables in each class in influencing the success of the student council (OSIS) university students, but if we look further, there are two variables that are the same in influencing the success of the student council (OSIS) university students, which are variables from high school province and student study programs.

Gestational diabetes (GDM) is defined by the World Health Organization (WHO) as any degree of glucose intolerance, beginning or diagnosed during pregnancy for the first time. The global prevalence of GDM is reported to be as high as 20%. This is why we initiated the present study. The main objective of this survey was to investigate the epidemiological profile of women with GDM in two referral hospitals of Yaoundé, Cameroon. This was an observational study with descriptive longitudinal historical design, conducted at the Yaoundé Central Hospital (YCH) and the Yaoundé Gynaeco-Obstetric and Pediatric Hospital (YGOPH). The study period was from January 2018 to January 2020 and the duration of the investigation was 7 months. Data was analyzed using SPSS software (Statistical Package for the Social Sciences) version 20. A total of 34 pregnant women with GDM were identified out of 652. The overall prevalence of GDM was 5.2%. The mean age of these women was 31.8±4.4 years. Most women were multiparous (15: 44.0%). Majority (21: 61.6%) were followed by both gynecologist and endocrinologist. Known cardiovascular risk factors found were mainly smoking (34: 100%), low sports practice (20: 58%) and family history of diabetes (21: 61.1%), with first degree predominance 17 (80.5%). The first antenatal consultation (ANC) in average was at 12±2.5 weeks. Most women were symptomatic with cardinal syndrome comprising polyuria (32: 94.2%), polydipsia (22: 64.1%) and polyphagia (21: 61.6%). Majority (25: 73.3%) were managed with Insulin.

Published: June 2022

Introduction: Physical activity is a promising strategy to maintain the benefits gained after completing conventional pulmonary rehabilitation in people with chronic obstructive pulmonary disease (COPD). Proponents of tele-rehabilitation and physiotherapy see the use of communication and information technologies as a way to increase access and increase care continuity. Therefore, the purpose of this study is a systematic review of randomized clinical trial and randomized controlled trials to investigate the effect of tele-rehabilitation on improving the physical activity of patients with COPD.Method: A systematic review was conducted in randomized controlled clinical trial studies without time limit by searching for keywords in the title, abstract and study keywords in the valid scientific databases Embase, Web of Science, Scopus, PubMed on October 20, 2021. The quality of the studies was assessed using the Joanna Briggs Institute(JBI)checklist; Studies with a score above 7 were analyzed. This study was conducted according to the Preferred reporting Items for systematic reviews and meta-analysis(PRISMA).Results: A total of 83 articles were identified after removing duplicates. After screening the full text of the articles, 10 studies met the inclusion criteria. Studies were classified into two categories: randomized trial (6.10, 60%) and randomized clinical trial (4.10, 40%). Input studies included 979 participants. The duration of intervention in each study ranged from 8 weeks to 18 months. The technologies used included video conferencing (1.10, 10%), cloud-based platform (1.10, 10%), mobile application (1.10, 10%) and telephone calls (6.10, 60%). In (6.10, 60%) of the studies, tele-rehabilitation interventions had similar improvements in both control (face-to-face) and intervention (tele- technology) groups. However, in (4.10, 40%) of the studies, the intervention group reported a significant improvement compared to the control group.Conclusion: The results of the present systematic review showed that although in most studies tele-rehabilitation interventions have the same results as traditional interventions, a well-designed tele-rehabilitation program to improve the physical activity of patients with COPD can supplement or replace the program. It is a traditional rehabilitation and improves the patient's health.

Randomized and controlled trial studies that used the Tele-rehabilitation approach as an intervention in the study and evaluated it in terms of cost-effectiveness were considered as inclusion criteria. Eligibility criteria were screened independently by two researchers. In order to evaluate the quality of the input studies to this study, the JBI quality evaluation checklist for randomized controlled trials was used. The same checklist was used to extract the data. The data elements in this checklist included the title of the publication, year of publication, country, number of participants, duration of intervention, technology-based approach, study population, study objectives and main findings of the study.Results: A total of 11 articles with inclusion criteria were included in the study. There was no significant bias in the studies and all studies had the quality of inclusion in our study. The Tele-rehabilitation approaches and health conditions evaluated in the studies were largely different. In (5.11, 45%) of the studies, Tele-rehabilitation interventions reported a significant improvement in the outcomes and clinical effects in the Tele-rehabilitation group versus the control group (face-to-face visit). In (7.11, 64%) of the studies, Tele-rehabilitation interventions were more cost effective than traditional rehabilitation interventions. However, in (4.11, 36%) of the studies, no significant difference was observed in the amount of money spent between the control and intervention groups. In addition, in 4 of the studies, no significant improvement in quality in the adjusted years was reported.Conclusion: The evidence from this study shows that Tele-rehabilitation services and care for the general public are more cost effective than face-to-face rehabilitation services. It is suggested that future studies to maximize the potential of tele-rehabilitation focus on improving patients' access to rehabilitation services and removing barriers to tele-rehabilitation.

Published: June 2022

Külliye, Nevşehir ili Ürgüp İlçesi sınırları içerisinde yer almaktadır. Kaynaklarda Damsa olarak bilinen yerleşimin bugünkü adı Taşkınpaşa’dır. Emir Taşhun tarafından yaptırılan külliyenin kesin inşa tarihi bilinmese de tarihi kaynakların bize verdiği bilgiye göre 14. yüzyılda yapıldığı belirtilmektedir. Mimari yapıların tamamlayıcı unsuru olan süslemeler yapılarla bir bütünlük arz etmektedir. Bundan dolayı sadece yapılarımızı değil üzerindeki süsleme programını da korumamız, yaşatmamız ve gelecek kuşaklara aktarmamız gerekmektedir. Bu amaçla yapılan restorasyonlar eserlerimizi geleceğe taşımaktadır. Hatırı sayılır sayıda restorasyon uygulamasında eserlerin geleceğe taşımaktan çok eski halini arattığı belirtilebilir. Günümüze yakın tarihlerde yapılan cami ve hanigahın restorasyonunda da benzer hatalarla karşılaşılmaktadır. Çalışmamızda sadece külliye bünyesindeki hatalı restore edilen süslemeler irdelenecektir. Bu hataların nerede yapıldığı çizimler ve fotoğraflar eşliğinde incelenecek, eski fotoğraflarla özgün halinin nasıl olduğu ortaya konulacaktır.

The high mountain perennial pea Vavilovia formosa (Steven) Fed., commonly known as beautiful vavilovia, is a rare species of the high alpine flora of Armenia bound to scree habitats. Populations of V. formosa in Armenia, as well as in other regions of the world, are endangered and need to be studied and preserved both in natural and ex situ conditions. Studies of the relic alpine pea V. formosa, unique in its bioecological features and beauty, were initiated in Armenia in the20-30s of the last century and continue at the present time. Thanks to numerous expeditions tothe hard-to-reach habitats of Vavilovia in the Gegham and Syunik highlands, Zangezur ridge, manyresearchers of the Armenian flora collected herbarium material, conducted ecological and cоenoticstudies, analyzed karyology on the basis of local populations, repeatedly conducted experimentson growing Vavilovia in laboratory conditions and in botanical gardens of Armenia. As a result of fieldobservations, information was obtained on the status of Vavilovia populations in different regionsof the republic, in natural conditions, floristic and coenotic composition of habitats at the Aknasarand Sevkatar (Sevsar) mountain peaks, on slopes near the Aknalich lake, of the Mets Ishkhansarmountain, and near the Ughtasar mountain peak. One of the main natural threats leading to thechange in and shrinking of Vavilovia populations is the overgrowth of mobile scree habitats with turf-forming grasses, which creates conditions for the development of mountain-meadow vegetationon screes. The ex situ conservation strategy for V. formosa is one of the possible ways to evaluateits adaptive capacity to environmental changes, as well as to conserve it and use in basic andapplied research. An experiment on the introduction and cultivation of Vavilovia conducted by theYerevan and Sevan Botanical Gardens of Armenia has yielded some data on biomorphological andecophysiological features in ex situ conditions.
Influence of a lick-briquette on the mine-ral composition and guality of cows milk

Numerous experiments have shown that the organism of animals should receive in optimal proportions along with feed a sufficient amount of minerals, which determines their physiological status. Minerals together with feed additives in the process of absorption enter the milk. On average, a productive cow's milk contains up to 1% of minerals. Dagestan Republic, due to natural, climatic and zonal features, is experiencing a shortage of minerals in the soil and pasture vegetation. In this regard, their content in feed is insufficient to maintain the optimal level of the animal organism. Long-term shortage leads to a breakdown of metabolic processes, which leads to the development of diseases associated with their deficiency. Recently, to compensate the lack of minerals, feed additives in the form of mineral licks - briquettes are widely used. The paper presents data, obtained as a result of a scientific and economic experiment in the Tarumovsky district of Dagestan Republic. The experimental group of dairy cows, along with the main diet, additionally received a lick - briquette, in dose 4 kg. According to the results of the researches, a beneficial effect of a lick - briquette on the mineral composition of the milk of the experimental group of cows was established, with an increase in potassium, sodium, magnesium, calcium and phosphorus, respectively, on 2.94; 100.0; 46.15; 11, 40; 52.45%; iron, manganese, zinc, copper, cobalt, selenium and iodine (protein-bound iodine) - on 60.0; 107.14; 118.18; 21.31; 98.27;131.1; 179.50%, compared with control. Consequently, with an increase of the level of minerals, the qualitative composition and technological properties of milk improve as a valuable product for human nutrition.

The article deals with the problem of vertebrates animal spleen variation (fish, amphibians, reptiles, birds, mammals). The paper examines healthy vertebrate animals spleen during physiological ripeness of 16 species: common pike Esox lucius (L.1758), perch Perca fluviatilis (L. 1758), tench Tinca tinca (L. 1758), green toad Bufo viridis (L. 1768), lake frog Pelophylax ridibundus (P. 1771), sharp-faced frog Rana arvalis (N., 1842), steppe viper or west steppe viper Vipera ursinii (B. 1835), marsh turtle Emys orbicularis (L. 1758), nimble lizard Lacerta agilis (L. 1758), guinea hen Numida meleagris (L. 1758), mallard or mallard duck Anas platyrhynchos (L. 1756), quail Coturnix coturnix (L. 1758), guinea pig Cavia porcellus (L. 1758), common beaver and river beaver Castor fiber (L. 1758), domestic rabbit Oryctolagus domesticus (L. 1758), northern bat Eptesicus nilssonii (K., 1839). Results of morphometric studies indicate following forms: elongated with different variations, rounded, oval, wrong triangular; literature data: elongated, like a suit butterfly hemispherical, trapezoidal, rectangular, in the form of "Ladybug", crescent and bean-like structure. The shape of the organ being studied is varied and often variable which is related to the peculiarities of the internal abdominal organs in embryogenesis. The shape of the spleen depends on the shape and structure of the animal's body (if the body is compact, it is rounded or oval; if the body is extended in the caudal cranial direction, it is triangular or elongated with different.

Indazole compounds are intensively used in the synthesis of new active substances for pharmacological purposes. The present work includes methods of modification and preparation of new indazole compounds, determination of their biological activity (antibacterial properties, antiprotozoal and fungistatic activity). Modification methods were used: the recyclization reaction; acetylation of the amino group; acylation and others. We have synthesized indazole derivatives containing an aryl substituent with a 2-aminoethyl fragment by recyclization of 1-(2-chloroaryl)-3,4-dihydroioquinolines under the influence of hydrazine. The starting structures for the synthesis of indazoles (compounds 5, 6, 7) possess negligible activity toward Colpoda steinii, are practically inactive toward Penicillium italicum but retard the growth of E. coli and Staphylococcus aureus (retard zone 7-9 mm); compounds with dimethoxy groups in the benzene ring (compounds 5 and 6) are active toward E. coli whereas structure 7 has no activity without dimethoxy groups. The recycling reaction leading to indazole structures considerably increases the activity of all compounds (1-4, 8-14). Compounds with a primary amino group (structures 1, 2, and 9) possess marked antiprotozoan activity, the best results in this respect being demonstrated by compound 9 which does not contain dimethoxy groups in the benzene ring (15.6 ?g/ml). Acylation of the amino group in compound 2 allows a 4-fold increase in antiprotozoic activity and a slight fungistatic activity (compound 3). At the same time, acylation with a bulkier and more lipophilic benzoyl group (compound 4) practically suppresses antiprotozoic and fungistatic activities. It should be noted that conversion of the primary amino group of compounds 1 and 9 to the tertiary amino group (compounds 13 and 14) allows a dramatic increase in antiprotozoal activity (31.25 µg/ml for compound 1 and 3.9 µg/ml for compound 13; 15.6 µg/ml for compound 9 and 3.9 µg/ml for compound 14). In addition, these same compounds 13 and 14, unlike compounds 1 and 9, are active against all cultures studied. The best results are shown by compounds 11 and 12 in which the amino group is part of the urea structure.
