Authors: Ayuni Jamal Nur , Yusof Farazila , Ahmad Yusilawati , Hidayah Nordin Norhuda , Sulaiman Suraya
Published: January 2022

In the present study, the addition of tin (Sn) to the pure Al system was done, and its effects on the morphology, density, and compressive yield strength of pure Al were analyzed systematically. In this context, the morphology of sintered Al revealed enhanced wettability and sintering response between Al particles with increased Sn content. Moreover, physical characteristics of sintered Al alloys demonstrated oxidation phenomenon (black color specimen) with the lowest Sn content of 1.5 weight percent (wt.%), in which a higher Sn content of 2 and 2.5 wt.% produced silver color specimens, implying a reduction in oxidation. Additionally, densification of sintered Al alloys was greatly promoted with increased Sn contents, suggesting effective wetting as confirmed by the previous morphological observations. Similarly, the compressive yield strength of sintered Al alloys improved with increased Sn content which might be due to the enhanced inter-particle contacts between Al particles and sufficient wetting by molten Sn. Based on the results obtained, the introduction of Sn powder at various contents improved the sintering response of pure Al powder by providing sufficient liquid-phase sintering. Therefore, the sintered Al alloys had enhanced the morphological, densification, physical characteristics, and compressive yield strength.
Ruminal Microbiome Manipulation to Improve Fermentation Efficiency in Ruminants
Authors: Ahmed Soltan Yosra , Kumar Patra Amlan
Published: January 2022

The rumen is an integrated dynamic microbial ecosystem composed of enormous populations of bacteria, protozoa, fungi, archaea, and bacteriophages. These microbes ferment feed organic matter consumed by ruminants to produce beneficial products such as microbial biomass and short-chain fatty acids, which form the major metabolic fuels for ruminants. The fermentation process also involves inefficient end product formation for both host animals and the environment, such as ammonia, methane, and carbon dioxide production. In typical conditions of ruminal fermentation, microbiota does not produce an optimal mixture of enzymes to maximize plant cell wall degradation or synthesize maximum microbial protein. Well-functioning rumen can be achieved through microbial manipulation by alteration of rumen microbiome composition to enhance specific beneficial fermentation pathways while minimizing or altering inefficient fermentation pathways. Therefore, manipulating ruminal fermentation is useful to improve feed conversion efficiency, animal productivity, and product quality. Understanding rumen microbial diversity and dynamics is crucial to maximize animal production efficiency and mitigate the emission of greenhouse gases from ruminants. This chapter discusses genetic and nongenetic rumen manipulation methods to achieve better rumen microbial fermentation including improvement of fibrolytic activity, inhibition of methanogenesis, prevention of acidosis, and balancing rumen ammonia concentration for optimal microbial protein synthesis.
Sexually Transmitted Infections in Pediatrics
Authors: Coronel-Martínez Diana , Augusto Moya-Barquín Luis
Published: January 2022

Sexually transmitted diseases (STDs) disproportionately affect young people, with more than half of the infections occurring in 15- to 25-year-olds, although as an age group they constitute only 25% of the sexually active population. Adolescents have been considered as a key and vulnerable population; adolescents are considered as marginalized populations (i.e., poor access to adequate health services, social and parental acceptance, stigmatization, among others. Every year, 87 million new cases of gonorrhea are reported worldwide in the population from 15 to 49 years old. In 2016, the estimated global prevalence of CT in 15-to 49-year-old women was 3.8% and in men 2.7%, with regional values ranging from 1.5 to 7.0% in women and 1.2 to 4.0% in men. The worldwide prevalence of HSV-2 among 15–49-year old is 11.3% and for HSV-1 among 0–49-year-old is 67%. These numbers alert us about the increase in the frequency of these diseases among young populations; more open sexual behavior could be an important factor for this increase; the treatment of these diseases is challenging due to the difficulties with detection and treatment; in the case of gonorrhea, it could become a major public health problem due to the emerging antimicrobial resistance; in the case of Chlamydia, despite the effective treatment, reinfection is still a possibility and for genital herpes, the disease can be controlled but not cured. This chapter will describe the most important aspects of these three diseases for supporting the clinicians and researchers about the management of sexually transmitted diseases in the adolescent population.
Ultrasound-Guided Brachytherapy for Cervical Cancer - A Tool for Quality Improvement in Brachytherapy?
Authors: Tharavichitkul Ekkasit , M. Galalae Razvan
Published: January 2022

Nowadays, brachytherapy is one of the major components to treat inoperable cervical cancer. Brachytherapy yields a higher dose to the target (cervix) while sparing normal tissues. Developments of brachytherapy stepped forward in the previous decade by image-guided brachytherapy (IGBT) turning brachytherapy from point-based planning to volume-based planning and IGBT improves the treatment quality for cervical cancer. Magnetic resonance imaging (MRI) or computed tomography (CT) is utilized in brachytherapy and showed promising results internationally. However, in a limited-resource area, the implementation of IGABT is difficult due to many causes (manpower, equipment, or budgets). To improve the quality in limited resources, ultrasound is introduced. The utilization of ultrasound in brachytherapy practice is to prevent uterine perforation during application. With present data, measurement by ultrasound showed the correlation to MRI measurement in uterine dimensions. With these aspects, there are many researches using ultrasound to improve the quality of treatment in brachytherapy, for example, to guide contouring on CT or to support brachytherapy planning. The use of ultrasound improves the quality of brachytherapy in comparison to conventional planning and supports the improvement in brachytherapy for cervical cancer.

Published: January 2022

Malaysia is one of the fastest emerging and developing countries in the world. To drive the economical workhorse, large amounts of power is required. The power demand has risen to 156,003 GWh per year in the year 2016, almost 30,000 GWh more than 5 years prior. Fossil fuels such as natural gas, coal, oil, and diesel have been the driving force powering Malaysia’s grids. However, these resources will not last forever, and they do harm to our environment. To counter this, renewable energy (RE) projects have been constructed all around Malaysia. This paper discusses on available and existing renewable energy systems (single/hybrid) in Malaysia and provides a comparison of their electricity generation capabilities. The renewable energy sources that are covered in this paper include Solar, Hydropower, Biomass, Tidal and Geothermal. At the moment, hydropower is the largest renewable energy producer, contributing to almost 15% of the country’s total energy generation. A lot of resources have been channeled towards the initiative of hydropower and it has definitely borne much fruit. This is followed by Solar Energy. Even though it is not as successful as hydropower, there is still a lot of avenues for it to grow in a tropical country like this. Malaysia is still relatively new in terms of power generation using biomass sources. There has been a gradual increase in the power generation using biofuels through the years and its future does look bright. Energy generation from wind, tidal, and geothermal sources has been rather challenging. Because of Malaysia’s geographical location, it experiences slow winds on average throughout the year. This has led to insufficient output for its financial input. Besides that, Malaysia also has relatively low tide, if compared to other Asian countries such as Indonesia and the Philippines. This contributed to the failure of tidal energy in Malaysia, but there have been signs of locations that can be suitable for this energy generation. Besides that, the country’s first geothermal power plant project failed due to a lack of preparation and discipline during the project’s execution. There is a high initial cost for geothermal projects, and the chances of failure are high if the necessary precautions are not followed. This could be one of the reasons why this branch of renewable energy has not been explored deeply.
Motifs for emphasizing corners in the characterization of corner infill buildings
Authors: Alfirević Đorđe , Simonović-Alfirević Sanja
Published: January 2022

The subject of the paper is corner infills in the urban environment. The term "corner infill" means an architectural object (house or building) that completes the continuity of two sequences of architectural objects that meet at an angle. One of the most important elements in the articulation of a corner house is the contact zone between the two external facades. Under certain circumstances, the so-called "corner theme" can become their meeting point. The corner theme in architecture implies a place that is emphasized in relation to the adjacent facade planes or the volumetry of the building. Although the principle of corner accentuation in architecture is present in most corner houses, there are numerous examples of urban infills in which the corner is not emphasized. That gives the impression that there are certain motifs or circumstances due to which the corner is accented or unaccented. The focus of the paper is not on the formal aspects of the corner articulation, but on analyzing the causes of the appearance of the corner motif. In the paper, characteristic examples of corner houses are considered through scientific analysis, and then the regularities are explored. The motifs that influence the emphasis of the angle in the interpolated building's composition were ascertained by the method of generalization. The aim of the research was to re-examine the position according to which the corner theme in urban infills is justified in situations when the house fits into the immediate urban environment of culturalhistorical or architectural significance. On the other hand, if the house is connected to surrounding buildings of lower quality or significance, the theme of the corner loses its meaning, because the whole house becomes a new city reference point, therefore emphasizing that the corner is superfluous.

Authors: Živković Dragan , Simonović-Alfirević Sanja , Gogić Sanja
Published: January 2022

At the time it was built, Hotel Majestic set the standards for elite hotels and for a high level of hotel management services in Serbia. Its owner, also the designer of the hotel, Milan Minić, fully carried out his intention for his hotel to stand out from other hotels, and become an elite and fashionable meeting place in Belgrade and in global high society. The building is a combination of architecture, fine and applied arts, and at the same time it represents high standards in design, construction and interior design, which makes it a significant authorial achievement of Belgrade's interwar architecture. The aim of this research was to analyze the architectural, urban, artistic and other characteristics of the Hotel Majestic building, in order to re-examine the view that Hotel Majestic was the forerunner of modern boutique hotels, and thus decades ahead of its time. Many authors have written about the characteristics of boutique hotels; however, the definition of the concept still remains vague. By comparative analysis of the available literature and by summarizing the results of this research, it can be concluded that Hotel Majestic fully meets all relevant criteria by which a boutique hotel can be recognized. The contribution of this research in the theoretical sense is reflected in the analysis and systematization of the most important interpretations of the concept of boutique hotels, as well as their basic characteristics. In the historiographical sense, the research provides a new insight into the so far unexplored area of boutique hotels in Serbia. Guidelines for further research could be directed towards discovering new examples of boutique hotels, as well as clarifying their definition and introducing them into legal regulations.

Published: January 2022

Modelling of the dynamic behaviour of elevators with high lifting velocities (contemporary elevators in building construction and mine elevators) is a complex task and an important step in the design process and creating conditions for safe and reliable exploitation of these machines. Due to high heights and lifting velocities, the standard procedures for dynamic exploitation are not adequate. With the purpose of identifying the basic parameters of the dynamic model (stiffness and damping), a unique method was applied, based on experimental measures for a concrete elevator. Due to the verification of this procedure, the experiment was conducted on a mine elevator in RTB Bor, Serbia. Simulations of the dynamic behaviour of an empty and loaded cage are presented using the obtained computational-experimental results

Published: January 2022

Background: The current coronavirus disease-19 (COVID-19) pandemic call attention to the key role informatics play in healthcare. The present study discovers an independent role of computerised tomography chest (CT) scans in prognosis of COVID-19 using classification learning algorithms. Methods: In this retrospective study, 57 RT PCR positive COVID-19 patients were enrolled from SMS Medical College, Jaipur (Rajasthan, India) after approval from the Institutional Ethics Committee. A set of 21 features including clinical findings and laboratory parameters and chest CT severity score were recorded. The CT score with mild, moderate and severe categories was chosen as response variable. The dimensionality reduction of feature space was performed and classifiers including, decision trees, K-nearest neighbours, support vector machine and ensemble learning were trained with principal components. The model with highest accuracy and area under the ROC curve (AUC) was selected. Results: The median age of patients was 55 years (range: 20-99 years) with 37 males. The feature space was reduced from 21 to 7 predictors, that included fever, cough, fibrin degradation products, haemoglobin, neutrophil-lymphocyte ratio, ferritin and procalcitonin. The linear support vector machine was chosen as the best classifier with 73.7 % and 0.69 accuracy and AUC for severe CT chest score, respectively. The variance contributed by first three principal components were 97.5 %, 2.4 % and 0.0 %, respectively. Conclusion: In view of low degree of relationships between predictors and chest CT scan severity score category as interpreted from accuracy and AUC it can be concluded that chest CT scan has an independent role in the prognosis of COVID-19 patients.
Major adverse cardiovascular events after implantation of absorb bioresorbable scaffold: One-year clinical outcomes
Authors: Šobot Tanja , Šobot Nikola , Bajić Zorislava , Ponorac Nenad , Babić Rade
Published: January 2022

Background/Aim: Bioresorbable vascular scaffold (BVS) represents a novel generation of intracoronary devices designed to be fully resorbed after healing of the stented lesion, delivering antiproliferative drug to suppress restenosis, providing adequate diameter of the coronary vessel and preserving the vascular endothelial function. It was supposed that BVS will reduce neointimal proliferation and that their late bioresorption will reduce the negative effects of traditional drug-eluting stents, including the late stent thrombosis, local vessel wall inflammation, loss of coronary vasoreactivity and the need for the long-term dual antiplatelet therapy. The purpose of this research was to investigate efficacy and safety of Absorb everolimus-eluting BVS implantation and the prevalence of major adverse cardiovascular events (MACE) at the mid-term follow-up. Methods: The study encompassed 42 patients selected for BVS implantation and fulfilling inclusion criteria - 37 male and 5 female - admitted to the Dedinje Cardiovascular Institute, Belgrade, Serbia over the one-year period (from January 2015 to January 2016) for percutaneous coronary intervention (PCI). Coronary vessel patency before and after stenting was assessed by the Thrombolysis in Myocardial Infarction flow (TIMI) grades. After the index PCI procedure with BVS all patients were clinically followed by regular (prescheduled or event-driven) visits during the next 12-month period. Results: In the intention-to-treat analysis, all Absorb BVS procedures were successful, without the need for conversion to other treatment modalities. The complete reperfusion (TIMI flow grade 3) after the intervention was established in 97.6 % of patients and 100 % of them achieved the TIMI flow grade ≥ 2. The presence of angina pectoris was reduced significantly by the BVS procedure: stable angina 57.1 % to 11.9 %, (p < 0.001) and unstable angina 31 % to 0 %, respectively (p < 0.001). After the one-year follow-up, the MACE rate was 11.9 %. Myocardial infarction occurred in 4.8 % and the need for PCI reintervention in 2.4 % of cases (not influenced by the gender or the age of patients). There were 4 cases of death (all patients were older and had lower values of left ventricular ejection fraction). Conclusion: The results of the current research demonstrated a high interventional success rate of the Absorb BVS implantation, followed by the early improvement of the anginal status. However, that was not translated into the favourable mid-term clinical outcomes, opening debate about the current status of Absorb BVS and the need for future refinements of stent design and implantation techniques.

Authors: Mihajlović Dalibor , Mihajlović Biljana , Todorović Nevena , Maksimović Žana
Published: January 2022

Background / Aim: More people die each year due to cardiovascular diseases (CVDs) than from any other cause. The most common cause of ischaemic heart diseases (IHD) is atherosclerosis of the coronary arteries. Risk factors for the development of coronary heart disease (CHD) can be preventable and non-preventable. The aim of the study was to determine the frequency of individual risk factors in patients with CHD. Methods: Retrospective analysis included patients with diagnoses of stable angina pectoris (AP), unstable angina pectoris and myocardial infarction - acute coronary syndrome (ACS) and ischaemic cardiomyopathy (iCMP). The prevalence of the following risk factors for IHD was analysed: hypertension, diabetes, obesity, cholesterol, smoking, family history, age and sex. Data were taken from the Register of Patients with Chronic Diseases and Risk Factors and electronic patient records. Results: Of the total number of respondents older than 18, 4.95 % had CHD. Of the 178 patients with IHD, 70 (39.3 %) patients had AP, 60 (33.7 %) patients had ACS and 48 (27.0 %) patients had iCMP. Positive family history had 63.5 % of patients, 72 % were older than 66, 24.1 % were smokers and 74.2 % of patients had elevated blood cholesterol levels. Diabetes mellitus affected 29.2 % of patients, hypertension 88.8 %, and BMI ≥ 25 kg/m2 had 70.8 % of patients. Of the total number of patients with ACS, 68.3 % were men, while higher percentage of women suffered from AP (62.9 %) (p = 0.002). In the age below 65, CHD was more common in men (p = 0.007). Cholesterol was elevated more often in patients with AP than iCMP (p = 0.001). Patients with ACS were more likely to have diabetes mellitus compared to patients with AP and iCMP (p = 0.010). Conclusion: The prevalence of preventable risk factors is alarmingly high. Of particular importance is the timely detection and treatment of risk factors by family physicians and strengthening the personal responsibility of each individual in choosing their lifestyle and active involvement in the therapeutic process.

Authors: Marinković Sonja , Đukanović Đorđe , Mandić-Kovačević Nebojša , Cvjetković Tanja , Uletilović Snežana , Maksimović Žana
Published: January 2022

Background/Aim: Organophosphorus compounds (OP) bind to acetylcholinesterase (AChE) causing an irreversible inhibition of the enzyme. When doing in vivo studies of OP intoxication, to precisely measure AChE activity in the brain tissue it is necessary to remove as much blood from the brain as possible. By doing so, interference of the OPs present in the blood is avoided. Usually this demands expensive equipment, therefore, the aim of this study was to find a simple and economical method to eliminate the blood from brain blood vessels. Methods: Wistar albino rats were divided into four groups named Control (C), Control washout (CW), Paraoxon (Pox) and Paraoxon washout (PoxW) group. Rats in Pox and PoxW were treated with 0.25 mg/kg paraoxon subcutaneously (sc), while C and CW received 1 mL/kg sc saline instead. The "Marinković-Maksimović" ("MM") method was performed in rats from PoxW and CW groups. Activity of AChE was measured both in erythrocyte lysate and in brain tissue using spectrophotometry. Results: Macroscopic examination revealed that the elimination of blood was achieved in CW and PoxW groups. Activity of AChE in homogenised brain tissue was expectedly lower in the Pox and PoxW group, when compared to C and CW group, respectively. The CW group had a lower value of AChE activity in the brain tissue compared to C group, while activity of AChE in the PoxW group was statistically higher than in the Pox group (p = 0.044). Conclusion: The MM method provides good elimination of blood from the brain. Together with blood, present confounding factors that interfere with analysis in homogenised brain tissue, were also eliminated.

The study on the power of monofunctional reactive dyes: The influence of the ionic strength solution on coloring of cotton fabric
Authors: Ristić Nebojša , Mičić Aleksandra , Ristić Ivanka , Jovanović Anđela
Published: January 2022

Reactive dyes are the most popular dyes for dyeing cellulose fibers. The low affinity of dyes on cotton determines the presence of large amounts of electrolytes and additional substances in the dyeing bath. In recent years, methods for increased use of dyes with minimal consumption of chemicals and natural resources have been popular. The number of ions formed by the dissociation of electrolytes determines the ionic strength of the solution and has a promotional effect on exhaustion and fixation of reactive dyes. In this work, the influence of neutral salts (NaCl and Na2SO4) and alkali salt (Na2CO3) on the color intensity of cotton fabric by reactive dyes has been investigated. A bath with a higher ionic strength of neutral salt has a greater exhaustion of reactive dyes. The addition of an alkaline electrolyte to activate the chemical dye/fiber reaction has an additional promotional effect on the exhaustion of reactive dyes.

Quasi-Static Flooding Analysis Method of a Damaged Ship Considering Oil Spill and Cargo Load
Authors: Kim Ki-Su , Roh Myung-Il , Lee Seung-Min
Published: January 2022

When a ship is damaged at sea, it is important to predict its behavior as well as whether it is to sink or not. If the ship comes to an equilibrium, the equilibrium position and time should be estimated; otherwise, the time to sink should be estimated. Furthermore, flooding analysis should be carried out not only during the design stage of the ship for preventive reasons, but also after an accident for a better investigation of its causes. In addition, flooding analysis methods that can provide predictions in case of an accident are of particular importance, as there is no time for the required calculations in an emergency. For this purpose, a quasi-static flooding analysis method for the damaged ship in the time domain is proposed in this study. There are a number of studies in which the equilibrium position and time were estimated by flooding analysis. However, most of them have not considered the air pressure effect in fully flooded compartments, and the method of determining the fluid volume in these compartments was not accurate. In the present study, the virtual vent and accumulator method are used to calculate the reference pressure in the fully flooded compartments, and the compartment shape is considered by using polyhedral integration. Also, spilled oil and solid cargo items from the damaged ship are taken into account for realistic flooding analysis. Finally, the damage stability criteria were checked not only in the final state, but also during the entire time of the flooding, as the intermediate states can be more hazardous than the final state. To validate the feasibility of the proposed method, it was applied to a naval ship, which is considerably more stringent for damage stability. As a result, we checked the availability of this study.

Authors: SHI Rong , ZHAO Ying
Published: January 2022

At present, under the background of the increasing tide of "anti-globalization" and China's open economy of higher standards, it is of great practical significance for Suzhou to promote the construction of "single window" of trade facilitation. Therefore, based on the current situation of promoting the construction of "single window" for trade facilitation, this paper concludes that there are some problems, such as business coverage is limited, system functions are imperfect; information interconnection and intercommunication should be strengthened; the overflow function of "single window" is insufficient, the recognition degree need to be improved; the cross regional construction lags behind, and the integration of customs clearance in the Yangtze River Delta has not yet been realized. Furthermore, the article puts forward three countermeasures and suggestions, including clarifying the functional orientation of the construction of "single window" with local characteristics in Suzhou; providing intelligent and integrated value-added services in combination with industrial chain extension and supply chain process; and promoting the "interconnection" of Yangtze River Delta and actively seeking for complementary and docking resources.
