Minimizing Greenhouse Gas Emissions From Ships Using a Pareto Multi-Objective Optimization Approach
Authors: Domachowski Zygfryd
Published: July 2021

To confront climate change, decarbonization strategies must change the global economy. According to statements made as part of the European Green Deal, maritime transport should also become drastically less polluting. As a result, the price of transport must reflect the impact it has on the environment and on health.

In such a framework, the purpose of this paper is to suggest a novel method for minimizing emissions from ships, based on so-called Pareto multi-objective optimization. For a given voyage by a ship, the problem is to minimize emissions on the one hand and minimize fuel consumption or passage time on the other. Minimizing emissions is considered as the preferred objective. Therefore, the objective of minimizing fuel consumption or passage time needs to be reformulated as a constraint. Solving such a problem consists of finding most favourable path and speed for the ship and satisfying the optimization criteria.

Relatively new systems such as hybrid diesel–electric systems have the potential to offer significant emissions benefits. A hybrid power supply utilizes the maximum efficiency of the direct mechanical drive and the flexibility of a combination of combustion power from the prime mover and stored power from energy storage from an electrical supply, at part load and overload.

A new report by the American Bureau of Shipping suggests that maritime transport is likely to meet the International Maritime Organization’s target by 2030, solely by using current technology and operational measures. However, this would not be enough to attain the target of reducing CO2 emissions by 2050 by at least 50% compared to 2008. New technologies and operational methods must be applied.

Formulating a stand-alone paradigm of the concepts Bankruptcy and Insolvency of legal entities
Authors: ZHIL'TSOVA Yuliya V. , STRAKHOV Vladimir A.
Published: July 2021

Subject. The terms, such as Bankruptcy and Insolvency, are used in various regulatory documents of the Russian Federation. The protracted economic crisis due to the pandemic urges to solve disputable issues and improve the legal framework of the business bankruptcy procedure.
Objectives. The study provides a rationale for formulating standalone paradigms for bankruptcy and insolvency for scientific and practical purposes, aligning development phases of the national institution of bankruptcy.
Methods. The study relies upon general and partial methods of research. Based on the retrospective analysis, we sorted evolutionary phases of bankruptcy as a national institution. Conducting a comparative analysis, we inferred the inequality of the two synonymous concepts.
Results. Based on the comprehensive approach to dealing with disputable issues, we provided a rationale for diverging bankruptcy and insolvency. We believe that the reconstruction should start with the renaming of the respective federal regulation, being followed by developing its content. We analyzed various approaches to comparing insolvency and bankruptcy, spotlighted development milestones of the national legislation and presented our own vision of the origination of bankruptcy as a national institution, pointing out five phases and naming each of them.
Conclusions and Relevance. The term Bankrupt is of European origin and came to Russia during the reign of Peter the Great. Currently, the terms Bankruptcy and Insolvency permeate not only the lexicon of the professional community of economists and lawyers, but also ordinary people. We conclude it would be reasonable to diverge bankruptcy and insolvency at the paradigmatic level, which will contribute to the improvement and development of modern scientific views and practices of professionals in economics and law. The system of the bankruptcy development as a national institution is intended to sort out scientific ideas of its historical process. The ideas herein are designated to set up a modern paradigm of bankruptcy and insolvency, and improve the legislative framework. Therefore, the conclusions and suggestions can be of scientific and practical use in economics and law, as well as in higher education.
Improving the tax system of Uzbekistan
Authors: SIDOROVA Elena Yu. , DZHURAEV Anvar V.
Published: July 2021

Subject. The article spotlights directions of the tax system and fiscal policy, which induce the economic growth in Uzbekistan, sustainability of its tax system, and address key goals of the socio-economic development.
Objectives. We evaluate the current reforms intended to improve the tax system of Uzbekistan during the globalization of the world economy, and formulate relevant recommendations.
Methods. The study uses analytical methods to process publicly available data.
Results. The tax practice of Uzbekistan is found to demonstrate a disparity in tax burden in case of the general and simplified tax treatment, i.e. a comparatively big gap between taxes paid by taxpayers. To reduce the disparity, it is necessary to dramatically alleviate the tax burden and facilitate general taxation rules. Furthermore, to create the equitable and fair tax system, tax benefits should be gradually abolished, since they seriously reduce the income of people. A reduction in the VAT rate may help change the simplified tax treatment into the general one.
Conclusions and Relevance. If the proposed actions are implemented, Uzbekistan will be able to establish a modern taxation model, eliminate the systemic disparity and inequality, and, ultimately, create effective social institutions driving the sustainable economic growth. There should be the fiscal mechanism for net profit or income, value added, with the concurrent abolishment of the turnover tax, which contradicts international tax practices.

Authors: PREOBRAZHENSKII Boris G.
Published: July 2021

Subject. This article analyzes the effectiveness of government-sponsored schemes.
Objectives. The article aims to analyze the use of tools to assess the effectiveness of public programmes in the management of regional development and assess the preference for the use of certain analytical tools.
Methods. For the study, I used a comparative analysis, and the systems, logical and structural, and descriptive approaches.
Results. The article classifies the prerequisites for monitoring the implementation of public programmes, performs a content analysis of methodological approaches to assessing the effectiveness of State (regional) programmes, and presents an interpretation of the results of their comparison.
Conclusions. A comprehensive assessment of the quality of programme implementation management should correspond to the development goals of the modern management paradigm; when evaluating the effectiveness and efficiency of programme implementation, it is necessary to take into account the individual nature of meso-economic systems. Adjusting the trajectory of programme implementation involves taking into account the principle of derivation when making preventive decisions at different levels of the management hierarchy.

Is overlooking workplace incivility just like experiencing “boiling frog syndrome”? Uncivil behaviours at workplace and their major negative consequences and how to reduce their negative outcomes
Authors: BİÇER Can
Published: July 2021

Millions of people go to work every day but only very lucky ones don’t experience incivility at workplaces. Unfortunately, majority of the employees are the victims of verbal aggression, emotional abuse and even violence any time in the organizations. Workplace incivility simply means rude, hidden aggressive and discourteous behaviors and it can be dangerous for both the organizations and the workplaces. Workplace incivility has been somewhat overlooked due to its less intense nature comparing to aggression. In fact, usually the instigator of an uncivil behavior is not even aware of the harmful effects of his/her act toward the victim. Workplace incivility is often overlooked but it might cost too much for the organizations since it leads to poor workplace climate, job dissatisfaction major negative outcomes like employee turnover and employee turnover. Whether intentional or not, from disrespecting other coworkers to verbal aggressions or insulting others, unacceptable behaviors should be detected by the management and the measures must be taken immediately to stop the negative consequences of the workplace incivility. In this conceptual study, uncivil behaviors at workplaces will be defined in detail, theoretical framework will be formed and the actions that must be taken to reduce and prevent incivility in the workplaces will be recommended.

Türkiye’de sürdürülebilir mavi ekonomi için balıkçılık desteklerinin değerlendirilmesi
Authors: TOPLU YILMAZ Özlem
Published: July 2021

2008 Küresel Krizi sonrası ortaya atılan “mavi ekonomi” kavramı okyanus tabanlı büyüme stratejisi olarak görülen; sürdürülebilir deniz ve okyanus kaynaklarının sağlanmasını amaçlayan bir konsepttir. Mavi ekonomi, balıkçılıktan deniz ticaretine, kıyı gelişiminden turizme, gemi yapımından, yenilenebilir kaynakların üretilmesine kadar, deniz ve okyanuslar içindeki tüm üretim ve pazarlama faaliyetlerini kapsamaktadır. Bu çalışmada mavi ekonomi bileşenlerinden biri olan balıkçılık üzerinde durulmuş ve Türkiye açısından mavi ekonomi kavramı, balıkçılık faaliyeti çerçevesinde değerlendirilmiştir. Sürdürülebilir deniz kaynakları için balıkçılık faaliyetlerinin balık türlerinin tüketilmesine yol açmadan, aşırı avlanmayı önleyecek şekilde yapılması gerekmektedir. Aşırı avlanma nedeniyle balık stoklarında azalma Türkiye’de de önemli bir sorundur. Balıkçılık destekleri ve tekne sayısındaki artış aşırı avlanmanın nedenleri olarak gösterilmektedir. Bu çalışmada Türkiye’de toplam balıkçılık desteklerinin (özellikle yakıt desteklerinin) ve tekne sayısının balık üretimi (avlanma) üzerindeki etkileri Python programında analiz edilmiştir. Yapılan analiz sonucu, toplam desteklerin avlanmayı arttırdığı sonucuna varılmıştır. Tekne sayısının ve yakıt desteklerinin tek başına avlanmaya etkisinin ise az olduğu tespit edilmiştir. Mavi ekonomi ve balıkçılık desteklerinin avlanma üzerindeki etkisi Türkiye’de daha önce fazla çalışılmamış bir konu olduğu için, araştırma literatüre katkı sağlayabilir ve farkındalık yaratabilir.

Değişmeyen tek şeyin değişim olduğu bir ortamda kurumların varlıklarını sürdürülebilir kılmaları kurumsallaşmaları ile mümkün olmaktadır. Kurumsallaşma kavramı ilk olarak aile işletmeleri özelinde ortaya çıkan bir kavramdır. Aile işletmelerinin yaşam süreleri, işletme sahiplerinin yaşam süreleriyle sınırlı kalmakta ve işletmeler gelecek nesillere aktarılamamaktaydı. Kurumsallaşma kavramının gündeme gelmesiyle birlikte özel sektörde faaliyet gösteren işletmeler yoğun rekabet ortamında ayakta kalabilmek adına kurumsallaşmanın gereklerini yerine getirmeye başlamışlardır. Hizmette süreklilik ve kalite ile hizmetten memnuniyetin ön plana çıktığı belediyeler için de kurumsallaşma, bu hedeflere ulaşılması yönünde önemli bir şart haline gelmiştir. Belediye yönetimleri de vatandaşları memnun edebilmek ve gelecek seçimlerde de görevde olabilmek adına kurumsallaşmaya önem vermeye başlamışlardır. Bu kapsamda çalışmanın konusunu, kurumsallaşma ve kurumsallaşmayı sağlayan faktörlerin bir belediye özelinde incelenmesi oluşturmaktadır. Çalışma kapsamında literatürde genel kabul gören kurumsallaşma faktörleri kamu sistemine uyarlanarak incelenmekte ve ölçek geliştirilmektedir. Amaç, kurumsallaşma faktörlerinin kamu idaresi olan bir belediyede gerçekleşme düzeyini kurum çalışanları aracılığıyla tespit etmektir. Çalışmada anket yöntemi kullanılmaktadır.

Published: July 2021

The E2 glycoprotein is the target of broadly neutralizing antibodies against Hepatitis C Virus (HCV). There is evidence that the HCV E2-specific antibody glycosylation profile is associated with hepatic fibrosis progression. The main aim of this study was to compare the sialylation of E2-specific and naturally occurring antiglycan Abs to determine whether their combination could be beneficial for the non-invasive evaluation of hepatic damage. Fifty-eight patients with various stages of hepatic fibrosis or without were tested. The sialylation of HCV E2 glycoprotein-specific antibodies (E2-Abs), the Thomsen-Friedenreich antigen- and αGal glycotope-specific antibodies (TF-Abs, αGal-Abs) was analysed using the ELISA platform. The level of IgG Abs and their reactivity to Sialospecific Sambucus Nigra Lectin (SNA) were determined and changes in Abs sialylation were analysed based on the stage of liver fibrosis, HCV genotype and antiviral therapy efficacy. The late stage of liver Fibrosis (F4) was characterized by dramatically decreased E2-Ab SNA reactivity unlike stages with no fibrosis (P=0.003) and stages F1–F3 (P=0.0007). In contrast, antiglycan Abs showed an increased sialylation. In multiple regression analysis, the combination of E2 and TF-Abs sialylation patterns gave a significant advantage in assessing liver damage. A high rate of discrimination between F0 and F4 stages of fibrosis as well as between F1–F3 and F4 was obtained (ACC=0.948 and ACC=0.90, respectively). Thus, the combined analysis of disease-specific and natural Abs sialylation can remarkably enhance the clinical value of the approach in the non-invasive evaluation of hepatic damage.

Authors: Aluri Nandini  , Ravi G
Published: July 2021

Drugs are the critical elements in the health care system. They must be manufactured in the high-quality levels. End product testing by itself does not guarantee of the quality of the product. Quality assurance techniques must be used. In pharmaceutical industry, process validation performs this task, by ensuring that the process does what it purports to do. Validation is one of the important steps in achieving and maintaining the quality of the final product. If each step of production process is validated, we can assure that the final product is of the best quality. This study is intended to demonstrate and standardize the data that should be routinely included in the marketing authorization dossier describing evolution and validation of the manufacturing process and distinguish from the validation data which more properly fall under the remit of GMP inspection. During the study of critical process variables of sucralfate oral suspension were validated to demonstrate consistency of manufacturing process to produce the produce the product of desired quality. The validation studies were conducted which were intended for the use of commercial purpose so this validation study is concurrent type. All the in-process variables and finished product characteristics were monitored; the statistical analysis of data was carried out. Further from the results, it is inferred that the manufacturing process of sucralfate oral suspension was validated.

Authors: Hussain Qamar , Ghazanfar Sidra , Abdullah Muhammad , Ahmad Waqar
Published: July 2021

Purpose: The current study investigates the new impact of the language style of online reviews (figurative vs. literal) on customers' perceived credibility and purchase intention the use of figurative language to advertise product quality and social presence has been advocated in previous marketing research.

Design/Methodology/Approach: The theory of expectation is adopted that is developed by Victor Vroom, is used in this study. It claims that a person would act or behave in a certain way because they are motivated to choose a specific behavior over others because of the desired output of that activity. A Google Forms quiz was created to collect data from persons who have done online purchasing. They were divided into two groups. The sentiment is echoed by a sample of 334 Pakistani students. The results were assessed using structural equation modeling (SPSS).

Findings: The findings show that consumers' purchasing intentions are influenced by both the language style of online reviews and their perceived reliability. Literal reviews, as opposed to figurative reviews, can increase users' desire to purchase search products. Consumers' willingness to buy experience products may be improved through figurative reviews.

Implications/Originality/Value: In the context of Pakistan customer's trust in online shopping is not good. They think these platforms are not trustworthy. With the help of Literal reviews’, we can build customers' trust in online shopping.

Authors: Khan Qaisar Maqbool , Kouser Rehana
Published: July 2021

Purpose: Profitability measurement is a comparative statistic that describes the relationships between overall profit and other financial determinants of the firm.

Design/Methodology/Approach: The focus of this study is to measure the technical (TE), pure technical (PTE) and scale efficiency (SE) scores via Data Envelopment Analysis (DEA) of modaraba companies operating in Pakistan. The next stage is to study the empirical relationship between profitability, liquidity, leverage, and macroeconomic performance drivers. Financial statement data for 2010 to 2019 have been analyzed.

Findings: Empirical findings of descriptive statistics, correlation and regression were measured. These empirical results reveal that capital ratio (CR) and operating expenses to net income (OENI) had negative correlation with PTE, SE and TE. Whereas the age of the firm had a negative correlation with PTE and TE and positive correlation with SE, moreover, exchange rate (EXC) PKR to USD, log of total assets (LTA) and management expenses (ME) had negative correlation with SE and positive correlation with PTE and TE. Furthermore, inflation (INF) had negative correlation with PTE and positive correlation with SE and TE. Moreover, number of certificates (NOC) had negative correlation with SE and TE and positive correlation with PTE.

Implications/Originality/Value: Findings will be helpful to the management and policy makers for enhancing future financial performance by concentrating on these economic factors. More detailed and extensive data from the financial and non-financial aspects is suggested to support the hypothesized relationship of efficiency measures and determinants.
Tool Feed and Burr Size Influence on Wettability of Ti6Al4V Micro End-Milled
Authors: Ferreira Rodrigo , Lopes de Castro Martinelli Gabriel , Roger Rodrigues Alessandro , Teixeira Coelho Reginaldo
Published: July 2021

Surface texturing, using micro-milling, has promising applications in the industry of medical implants, since it can assist cell adhesion and thus improve osseointegration. Ti6Al4V alloy is used as implant material due to its excellent biocompatibility and high mechanical strength. However, those mechanical properties reduce machinability creating some challenges for micro-milling. The way to initially assess cell adhesion is using surface wettability, usually conducted with water. At the present work, micro-channels were machined in Ti6Al4V by micro end-milling with 500 µm width per 50 µm depth with 1000 µm distant from each other. The effect of feed per tooth (fz) on wettability was analysed and some interesting relations with burrs formed on channel walls were obtained. Values of feed per tooth were 3, 6, 12 and 15 µm. Wettability results showed that slotted surface is more hydrophilic on channel direction, with contact angles around 30° to 43°. In contrast, on the perpendicular direction the surface tends to be hydrophobic with contact angles between 75° and 146°. In addition, contact angle increases (hydrophobic tendency) as feed per tooth increases (along with roughness), even on channel direction. The presence of burrs also tends to disturb wettability results. Therefore, surface wettability depends on channel direction, burr size and tool feed per tooth, as well.
Influence of Abrasive Water Jet (AWJ) on Surface Roughness
Authors: Nader Ameer Jalil , Saad K. Shather
Published: July 2021

Abrasive water jet (AWJ) is one of the most advanced and valuable non-traditional machining processes because of its massive advantages of removing metals ranging from hard to soft. This paper focused on studying the influence of jet pressure, feed rate and standoff distance on surface roughness during cutting carbon steel using abrasive water jet cutting. A surface roughness device assessed the surface roughness by performing sixteen experiments to identify the distinct texture of the surface. Based on the experiences, the best surface roughness value was 3.14 μm at jet pressure 300 MPa, standoff distance 4mm and feed rate 30 mm/min. The Taguchi method was introduced to implement the experiments and indicate the most influential process parameters on average surface roughness. The experimental results reveal that feed rate has a significant effect on average surface roughness.
A Novel Design of Hybrid Hydrophilic-Superhydrophobic Surfaces for Fog Harvesting
Authors: Almusaied Zaid , Asiabanpour Bahram
Published: July 2021

The continuous growth in the human population and climate change exacerbates the problems related to water scarcity. Harvesting the atmospheric water can mitigate the water scarcity in many regions around the globe. Fog collection using hybrid hydrophilic-superhydrophobic surfaces has the capacity to achieve a higher water collection rate. In this paper, a new method and materials are introduced to create the hybrid surfaces. The method includes additive manufacturing- to make sheets with holes-, mixing and casting polymeric matrix composite, and a controlled spray coating mechanism. The materials comprised of hydrophobic coating on top of the acrylic printed sheet and hydrophilic composite. The ratios of the pitches to diameters of the hydrophilic regions varied during the experiments to obtain the best water generation. The water collection rate for the sample with diameters of 583 um and a pitch of 1600 um has achieved 57% more than the untreated hydrophilic sample. The contrast in wettability accomplished by this novel method has the potential to be implemented on a large scale for atmospheric water harvesting.
A User-Oriented Adaptive-Optimal Car Parking Management System Towards Smart Livings
Authors: Taiga Sato , Bakibillah A.S.M. , Hashikura Kotaro , Samad Kamal Md Abdus , Yamada Kou
Published: July 2021

Existing parking management approaches do not consider specific requirements, priorities, user comfort, or modes of use when allocating a parking spot in a large park. As a result, vehicles carrying multiple passengers but staying for a limited period often have to drive further, searching for a parking spot, which increases fuel consumption, emissions, waste of time, and discomfort of users due to extra walking distance. In this paper, we consider the need for both sustainability and comfortable livings in a future smart city and propose an adaptive-optimal scheme that takes advantage of parking efficiency based on the passenger information and flexibly provides the optimal parking spot to the individual. We presume that the management system has information about the number of users, user priority, and expected stay time when a car arrives or a parking request is made. The best parking slot is assigned based on the available parking slots and the given objectives, such as the shortest travel distance inside the parking zone for a low pollution, the shortest walking distance per user, or a combination of both with some trade-off. The decision process is fine-tuned using parking data obtained from a model of a large car park of a shopping complex, and the results of the proposed scheme are compared with other schemes. The findings indicate that overall time spent in the parking lot, as well as individual walking and travel distances, have significantly improved.

FTIR spectral studies of the binary solutions of acetone with xylene isomers
Authors: Naganandhini S.P. , Sangeetha T. , Arivazhagan G.
Published: July 2021

FTIR spectra of neat acetone (ACT), xylene isomers (o-xylene (OXY), m-xylene (MXY), and p-xylene (PXY)) and their binary solutions at various ACT molar concentrations are recorded in the range of 4000—400 cm–1. Although neat ACT is a mixture of monomers, dimers, and trimers, the number of dimers is larger than that of monomers/trimers, as suggested by a relatively higher intensity of the dimmer ν(C=O) band with respect to that of the monomers/tri­mers. The shifts suffered by some of the fundamental absorption bands of xylene isomers/ACT confirm the presence of (ACT)C=O⋯H(OXY/MXY/PXY aromatic C—H or methyl) and (ACT methyl)H⋯π(OXY/MXY/PXY) H-bonds in all the solutions but with different strengths, as suggested by different magnitudes of the vibrational band shifts. The asymmetric and symmetric stretching bands of either C—H or CH3 of OXY/PXY experience unequal force constants in ACTOXY and ACTPXY binary solutions with a 0.2 mole fraction of ACT. The νas(C—H) doublet due to the intramolecular coupling appears only in ACTOXY and ACTPXY binary solutions.
Customer Relationships in Banking: Does relationship strength influence relationship quality and outcomes?
Authors: Al-Wugayan Adel A
Published: July 2021

This study investigates how customer-bank relationship strength dimensions, reflected by relationship length, depth and width, influence the associations between customer-perceived relationship quality and relational outcomes in retail bank service industry. To date, it’s still unclear whether relationship strength could contribute to, or detract from, customer relationship quality and outcome. A total of 2,029 bank customers in Kuwait are surveyed and data collected is analyzed using PLS-SEM modeling to validate the proposed conceptual framework followed by Multi-Group Analysis to test study hypotheses. Obtained findings show that the linkages between relationship quality components (satisfaction, trust and commitment) and relational outcomes (loyalty and Word-of-Mouth) are affected by the level of relationship length and depth, while relationship width only influenced the association between satisfaction and relational quality. The inclusion of relationship strength that represents past customer behavior provides a more accurate and comprehensive view of the dynamics of the interrelationship between key antecedents and consequences of relationship marketing in the retail banking industry.
ROLE AND IMPORTANCE OF STHIRA BINDU (FIXED POINT) IN YOGA PHILOSOPHY
Authors: Subedi K. , Panthi D. , Jha K. , Bhatta C.R.
Published: July 2021

It is true that all living things and all the mechanisms of entire universe are guided by mathematical relations and results. The theory of fixed point is one of the most leading gears of modern mathematics and its results are the most generally useful in mathematics which gives the solution of non-linear problems of various fields of modern subjects [9]. Also, the human brain can perform the intellectual courses that still have not been performed by digital computers. It may therefore be seen that quantum mechanics is very much associated with the consciousness of mankind [21]. Yoga is one of the few ways to understand the eventual reality mentioned in Vedanta, quantum physics and mathematics as well [19]. This paper investigates the role and importance of fixed point in eastern philosophies especially with yoga along with meditation focusing that mathematics plays a significant role in yoga philosophy.

This practice brief describes the assessment project undertaken by the Sheridan Libraries at Johns Hopkins University as part of the library’s participation in ARL’s Research Library Impact Framework initiative to address the question “(How) do the library’s special collections specifically support and promote teaching, learning, and research?” The research team investigated how the Freshman Fellows experience impacted the fellows’ studies and co-curricular activities at the university. Freshmen Fellows, established in 2016, is a signature opportunity to expose students to primary-source collections early in their college career by pairing four fellows with four curators on individual research projects. The program graduated its first cohort of fellows in spring 2020. The brief includes a semi-structured interview guide, program guidelines, and a primary research rubric.

High temperature is a critical barrier in most cotton growing areas, limiting cotton growth and development. The present study aimed to evaluate the effects of foliar spray on KC 3 cotton variety grown under ambient (32.66°C) and high temperature (37.21°C) stress in open-top chamber (OTC) with a temperature of 5°C from the ambient temperature for 10d from flowering to boll development stage. Foliar spray of kaolin @ 3% and calcium carbonate @ 5% were sprayed separately to the set of pots both in ambient and elevated temperature on 70th day of flowering. Observations on morphological and physiological parameters were recorded on viz., plant height (cm plant-1), leaf area (cm2 plant-1), relative water content (%), canopy temperature (°C), SPAD, chlorophyll fluorescence (Fv/Fm ratio). Kaolin @ 3% foliar spray significantly increased the plant height, leaf area, relative water content, chlorophyll content and reduced the canopy temperature both in high temperature and ambient temperature conditions. Among these treatments, T2 - kaolin 3% (Ambient) followed by T5 - Kaolin 3% (elevated temperature of 5 °C) recorded higher values as compared to calcium carbonate treatment both in ambient temperature and high temperature condition.
Blood Glucose Detection Using 3-LEDs: Analytical Model

Calibration of non-invasive blood glucose measuring devices have an important role in the routine of people with diabetes. Continuous monitoring is one of the most efficient manner to control the disease. Besides the errors associated with the user, the calibration of such devices is the key point for obtaining reliable data. Researchers have failed to correlate the 2 near-infrared-light wavelength response from skin with the blood glucose level and then use it for diagnosing both upper and lower glycaemia status. The aim of this article is to purpose a mathematical model for calculating the blood glucose level using 3-LEDs with different wavelengths. It is presented and demonstrated all equations involved by using the theory of absorption of light by photoplethysmography. The final proposed equation can be calculated without using prior data obtained from patient. It can be concluded that it is possible to reduce the necessity of using calibration processes before acquiring data by a non-invasive device.
Congruence properties of indices of triangular numbers multiple of other triangular numbers

For any non-square integer multiplier \(k\), there is an infinity of triangular numbers multiple of other triangular numbers. We analyze the congruence properties of indices \(\xi\) of triangular numbers multiple of triangular numbers. Remainders in congruence relations \(\xi\) modulo \(k\) come always in pairs whose sum always equal \((k-1)\), always include 0 and \((k-1)\), and only 0 and \((k-1)\) if \(k\) is prime, or an odd power of a prime, or an even square plus one or an odd square minus one or minus two. If the multiplier \(k\) is twice the triangular number of \(n\), the set of remainders includes also \(n\) and \((n^{2}-1)\) and if \(k\) has integer factors, the set of remainders include multiples of a factor following certain rules. Algebraic expressions are found for remainders in function of \(k\) and its factors, with several exceptions. This approach eliminates those \(\xi\) values not providing solutions.

The number of population is increasing, and the competition is getting tougher. It requires companies to remain able to survive and be able to compete with other companies, especially with companies that have the same line of business. The increasing use of the internet today has caused many changes in various fields. Many efforts are made by the company to survive, including by providing the best service to its customers. The use of existing technology for developing information systems for handling customer complaints is expected to help companies improve the quality of their products or services. In company management, it is important to provide good quality service in order to increase customer satisfaction. By determining the priority for handling customer complaints, it is expected to improve the Key Performance Indicator (KPI) of engineers. The decision-making process using the simple additive weighting method is carried out by weighting each criterion. This research is expected to determine the priority of handling customer complaints so that it can help engineers in determining the priorities for handling existing complaints.

The development of e-commerce is growing very fast and cannot stop; it changes various sides of human life. This change is a big challenge for everyone, and this is a condition that must occur so that everyone can carry out activities more effectively and efficiently. This research produces a few kinds of Startup classification and Customer Relationship Management (CRM) classification. Furthermore, it provides C=R.S2 formula, a formula for developing CRM, and S=H.I2.M formula, a formula for developing a Startup. These two formulas were eventually evolving into the seven stages of Startup (the maturity level of Startup), where the seven steps are the stages in developing a Startup, starting from the local level to the international level. These seven stages work so that the Startup founder can gradually understand what needs and how to develop it by focusing more on CRM. The results of this study are a framework to be able to implement the seven stages. This research results from previous studies' development: The Development of Innovative CRM E-Commerce: The Case of Blibli. Com.
Notus in arte sua
Authors: Parisini Laura
Published: July 2021

Il saggio approfondisce alcuni aspetti peculiari della documentazione epigrafica urbana relativa ai mestieri del lusso, che, soprattutto nell’ultimo ventennio, si è rivelata una fonte preziosa per ricostruire la fisionomia del mercato esclusivo di Roma tra la fine della Repubblica e l’Alto Impero. Tuttavia, a prescindere dal suo significato economico e prosopografico, l’epigrafia dei professionisti del lusso è innanzitutto un segno rivelatore della psicologia sociale di questa vastissima categoria di lavoratori urbani. Dalle iscrizioni, che ricordano principalmente artifices e negotiatores di estrazione libertina, ma anche alcuni individui liberi di nascita, accanto all’irrinunciabile orgoglio di classe emergono infatti evidenti tracce di un condizionamento mentale derivato dai contatti con l’ideologia aristocratica, ostile e diffidente, se non addirittura sprezzante, nei confronti delle occupazioni e di chi le praticava. L’epigrafia dei mestieri del lusso si conferma dunque un efficace strumento per indagare la forma mentis dei ceti subalterni benestanti dell’antica Roma e il loro modo di rapportarsi alla società. Laura Parisini ha conseguito il titolo di dottore di ricerca in Storia Culture Civiltà presso l’Università di Bologna. I suoi interessi di studio riguardano principalmente la storia sociale e la storia delle professioni nel mondo romano, con particolare attenzione alle tematiche del lavoro femminile e del lavoro infantile. Ha inoltre collaborato con il Dipartimento di Civiltà e Forme del Sapere dell’Università di Pisa e con il Museo Civico di Modena per attività di ricerca in ambito epigrafico.
Iconografia e rituale funerario
Authors: Pizzirani Chiara
Published: July 2021

In ogni tempo e in ogni luogo, le immagini hanno rappresentato un codice di comunicazione dalla straordinaria ricchezza semantica. Così fu anche per Etruschi, Italici e Greci, che attraverso temi, scene e schemi iconografici crearono un vero e proprio mondo di significati e di valori, nel quale le singole comunità umane potevano rispecchiarsi al loro interno e autorappresentarsi verso l’esterno. Il linguaggio che le immagini parlano è però tutt’altro che immediatamente comprensibile all’osservatore moderno. Infatti, l’immaginario non è fotografia della realtà antica, ma è, al contrario, codice comunicativo arbitrario, meditato, filtrato in conseguenza della scelta di valori che la comunità – e il singolo individuo – decidono di affidare alla memoria collettiva. L’esegesi dei significati, spesso volutamente ambigui, che le immagini sottendono rappresenta una delle più affascinanti sfide della ricerca archeologica. Per la loro straordinaria portata semantica, figure e rappresentazioni furono presto integrate all’interno della ritualità funeraria, nei singoli corredi tombali, venendo a configurarsi spesso come vero e proprio manifesto ideologico del defunto o dei defunti che in quella sepoltura trovavano la loro ultima dimora. Chiave di lettura indispensabile per comprenderne la valenza semantica originaria è l’interpretazione del contesto nel quale erano inserite. La prospettiva contestuale nella lettura delle immagini funerarie è il trait d’union imprescindibile dei contributi che questo volume raccoglie. I saggi, inoltre, si coagulano attorno ad un tema di straordinaria rilevanza nella percezione antica: la prospettiva della morte e, eventualmente, del destino oltremondano. Il volume inaugura una serie di incontri e di riflessioni sul significato delle immagini nei contesti funerari che si propone di indagare in maniera ampia, contestuale e interculturale il problema della percezione antica dell’immaginario rapportato alla dimensione funeraria, dalla selezione, alla fruizione, all’eventuale rifunzionalizzazione del segno iconico.
