Maximum Entropy Closure Relation for Higher Order Alignment and Orientation Tensors Compared to Quadratic and Hybrid Closure
Authors: Papenfuss Christina
Published: January 2023

A closure relation expresses the fourth order orientation tensor as a function of the second order one. Two well-known closure relations, the hybrid closure and the maximum entropy closure, are compared in the case of a rotation symmetric orientation distribution function. The maximum entropy closure predicts a positive fourth order parameter in the whole range of the second order parameter, whereas the hybrid closure results in negative fourth order parameters for small values of the second order one. For the maximum entropy closure quadratic fit polynomials are presented. For a general distribution without rotation symmetry, the expression for the entropy is exploited to derive an explicit form for the maximum entropy distribution. Lowest order approximation of this distribution function leads to simple closure forms for the fourth order alignment tensor and also for higher order alignment tensors.

Objective: To determine the risk factors and prevalence of catamenial asthma among women globally. Methods:This research employed a cross-sectional study design to gather and analyze the relevant data that leads to its findings. Wang and Cheng describe a cross-sectional study as an observational study that analyzes data from a population at a single point in time. Cross-sectional studies are helpful when establishing preliminary evidence while planning for a more advanced study in the future. Cross-sectional research requires researchers to record information, but not manipulate variables, as the case in this research study. Results:Study included 437 female participants. They had their menarche at different ages. They had their first menstrual period between the age of 12-14 years (n= 187, 42.8%) and between the age of 10-12 years (n= 176, 40.3%). It is noticed from the table that half of study participants experience worsening of asthma symptoms during menstruation (n= 219, 51.1%). More than half of study participants take painkillers medications for menstrual pain (n= 266, 60.9%). The last premenstrual asthma experience was before more than 1 year among 247 participants (56.5%) while it was before less than 1 year among 190 participants (43.5%). Most of study participants encountered it 2 times (n= 142, 32.5%) or 3-4 times (n= 140, 32%). The most frequent approach was via doctors advice (n= 205, 46.9%) followed by using over the counter drugs (n= 176, 40.3%). On the other hand, 20 participants just let it pass without any management (4.6%) and 36 participants attended at the emergency department (8.2%). Conclusion: Study results showed that most participants had their menarche at the age of 12-14 years. and more than one third of them encounter symptoms of catamenial asthma. Most of participants depend on doctors advice regarding the management with some of them attend at the emergency department to relieve their symptoms. More than half of study participants dont know how to manage their symptoms and avoid risks related to exposure to catamenial asthma.

Introduction: Asthma is a chronic respiratory disorder characterized by airway inflammation and hyperreactivity. Prevalence has continued to climb in recent decades as Western food habits have become more popular. Methods: We searched PubMed, Embase, and Scopus (January 2000--October 2022) for randomized clinical trials that evaluated the effects of diet in adults with asthma. Results: Among the 12,215 studies that were searched, only 12 were included. Obese people with asthma may benefit from a drop in weight of at least 7.5% from baseline due to calorie restriction. The influence of a diet high in items with putative antioxidant effect on asthma management was small and not clinically significant. Antioxidant supplements studies have shown positive results, with magnesium supplementation improving asthma management and vitamin C supplementation slowing the decrease of lung function. Studies on the impact of fatty acid supplementation on weight reduction, asthma management, and lung function all showed positive results. Propolis and caffeine have been shown to significantly improve lung function in clinical trials. But the opposite was found in research on high salt diets and lung function reductions. Conclusions: For individuals who are overweight and suffer from asthma, the optimal dietary strategy seems to be calorie restriction rather than focusing on individual food groups.

Published: January 2023

Background

Major depressive disorder (MDD) is the leading cause of global disability; however, the existing treatments do not always address cognitive dysfunction—a core feature of MDD. Immersive virtual reality (VR) has emerged as a promising modality to enhance the real-world effectiveness of cognitive remediation.

Objective

This study aimed to develop the first prototype VR cognitive remediation program for MDD (“bWell-D”). This study gathered qualitative data from end users early in the design process to enhance its efficacy and feasibility in clinical settings.

Methods

Semistructured end-user interviews were conducted remotely (n=15 patients and n=12 clinicians), assessing the participants’ perceptions and goals for a VR cognitive remediation program. Video samples of bWell-D were also shared to obtain feedback regarding the program. The interviews were transcribed, coded, and analyzed via thematic analysis.

Results

End users showed an optimistic outlook toward VR as a treatment modality, and perceived it as a novel approach with the potential of having multiple applications. The participants expressed a need for an engaging VR treatment that included realistic and multisensorial settings and activities, as well as customizable features. Some skepticism regarding its effectiveness was also reported, especially when the real-world applications of the practiced skills were not made explicit, as well as some concerns regarding equipment accessibility. A home-based or hybrid (ie, home and clinic) treatment modality was preferred.

Conclusions

Patients and clinicians considered bWell-D interesting, acceptable, and potentially feasible, and provided suggestions to enhance its real-world applicability. The inclusion of end-user feedback is encouraged when developing future VR programs for clinical purposes.

Published: January 2023

The Covid-19 pandemic affects many aspects, including transportation. Campaigns to reduce social distance have changed people's daily travel behaviors. Moreover, increased health awareness leads to increased bicycle usage, including in Jakarta. However, the lack of proper bicycle lanes along the road in Jakarta makes cyclists unsafe. Therefore, the Bicycle Level of Service method uses to evaluate the feasibility of a section of the bicycle lane in South Jakarta. As the number of cyclists in Jakarta grows, so do their characteristics. The diversity of cyclists may also reveal facility preferences. Hence, the Latent Class Analysis is carried out to determine a cyclist’s class likelihood. A sample of bicycle users in Jakarta and its surroundings was studied using descriptive quantitative analysis. Lastly, this study performed the cross-tabulation analysis to examine the relationship between cycling classes in Jakarta and the preferences on cycling facilities during the pandemic. The study results indicate that daily mobility in Jakarta changed during the pandemic, with an increase in bicycle users and the emergence of three cyclist classes: Recreational, Sport, and True. In addition, the feasibility evaluation of the existing bicycle lane shows an increase in the bicycle level of service since the time prior to the pandemic.
The Characteristics of Density Distribution and Densification on Medium and Small Indonesian Municipalities
Authors: Bimantara Aria Leo , Roychansyah Muhammad Sani , Ogawa Keiichi
Published: January 2023

While many studies on urban compactness measured built-up area (intensity), this study explored population density in forms of gradients. Also, medium and small cities (in this case, municipalities due to having autonomous economies), through inquiring their characteristics in common, could provide early insights for anticipating further growths. Density database was made, combined with cadastral data. Two kinds of urban growth pattern (i.e. concentric and linear) were comprehended to extract gradient patterns from the cities using three indices. Through assigning a time span (2010–2018), the densification rates were also derived. The results indicate that there was a transformation from linear to concentric pattern while populations increased, yet not rare to total sprawling. Besides, there were influences on the compactness states from how the cities are positioned among the others within their local clusters where, on one hand, being too close to large cities would promote sprawling in long term while, on the other hand, being surrounded evenly by other cities is likely advantageous. Nevertheless, the degree of these advantages was not prevailing fairly across the Indonesian regions. Given the complexity and multidisciplinary nature of urban form, these findings are considerable for further planning and studies.

Published: January 2023

Menurut laporan tahunan Komisi Nasional Anti Kekerasan terhadap Perempuan (Komnas Perempuan), angka kasus kekerasan seksual terus meningkat setiap tahunnya. Data kasus kekerasan seksual yang terus meningkat mendorong perlunya payung hukum yang dapat melindungi korban. Oleh sebab itu, Komnas Perempuan melalui usulannya mendesak pemerintah untuk segera mengesahkan Rancangan Undang-Undang Penghapusan Kekerasan Seksual (RUU PKS). Melalui Dewan Perwakilan Rakyat (DPR) yang mendapatkan mandat dari rakyat untuk mewakili suara mereka justru seolah tutup telinga akan masukan dan kritikan rakyat. Banyaknya kasus yang terus mencuat tidak lantas membuat DPR segera mengesahkan RUU PKS sehingga menimbulkan berbagai persepsi negatif dari masyarakat terhadap kinerja DPR. Oleh karena itu, kajian dalam artikel inii berusaha melihat sentimen masyarakat terhadap kinerja DPR dalam proses perumusan RUU PKS menggunakan metode big data. Data yang digunakan diambil dari media sosial Twitter. Kemudian, data diolah menggunakan text network analysis dan sentiment analysis untuk melihat persepsi dan sentimen masyarakat terhadap kinerja DPR atas tertundanya RUU PKS. Dari hasil persepsi dan sentimen masyarakat tersebut, lalu kami berusaha menganalisis model representasi yang dilakukan oleh DPR dalam konteks perumusan RUU PKS. Hasil sentiment analysis menunjukkan bahwa sentimen negatif mendominasi respons masyarakat atas tertundanya pengesahan RUU PKS. Pada analisis dengan menggunakan model representasi, diketahui DPR RI memiliki gaya/model perwakilan trustee dilihat dari adanya jurang yang lebar di antara tuntutan rakyat dengan kebijakan yang dihasilkan oleh DPR.

Published: January 2023

Abstract: Traffic congestion is a major problem in many cities of India along with other countries. Failure of signals, poor law enforcement, and bad traffic management has to lead to traffic congestion. One of the major problems with Indian cities is that the existing infrastructure cannot be expanded more, and thus the only option available is better management of the traffic. Traffic congestion has a negative impact on the economy, the environment, and the overall quality of life. Hence it is high time to effectively manage the traffic congestion problem. In cities, where the number of vehicles continuously increases faster than the available traffic infrastructure to support them, congestion is a difficult issue to deal with and it becomes even worse in case of car accidents. There are various methods available for traffic management such as video data analysis, infrared sensors, inductive loop detection, wireless sensor network, etc. Traffic congestion is a major problem in many cities of India along with other countries. Failure of signals, poor law enforcement, and bad traffic management have led to traffic congestion. This problem affects many aspects of modern society, including economic development, traffic accidents, increase in greenhouse emissions, time spent, and health damages.

Published: January 2023

Abstract: Historically, libraries have employed barcode-based book management systems for book identification, self-check-in, anti-theft, inventory control, and book classification. The process is manual. We suggest an RFID-based library management system that allows for quick transaction processing and streamlines the borrowing and returning of books from libraries with minimal manual labour. The suggested system has the ability to store data electronically that can be read by a reader. Using RFID tags, the system can issue and receive books. It can also use library databases to compute relevant factors like due dates, renewal dates, and fines.

Published: January 2023

Abstract: This brief review presents the international approaches to assessment of the content of geotaxis impurities (residual solvents and various inorganic and organic impurities) in pharmaceuticals. Nowadays, it has become necessary to provide not only purity profile but also impurity profile of a particular pharmaceutical product because of national and international regulations. The supply of essential medicines of good quality has been identified as one ofthe pre-requisites for the delivery of health care system of any country as poor quality medicines can harm or even kill consumers. The presence of unwanted chemicals in a particular medicine, even in extremely small quantities, may influence its efficiency and safety. Unlike in other industries, a medicine is a dynamic product whose color, consistency, weight, and even chemical identity can change between manufacture and ultimate consumption. Impurities in pharmaceutical products are of great concern not only due to the inherent toxicity of certain contaminants, but also due to the adverse effect that contaminants may have on drug stability and shelf-life. In pharmaceutical and drug products, impurities are the unwanted chemicals (organic, inorganic and residualsolvents) that remain with the active pharmaceutical ingredients (APIs), or develop/added during formulation, or upon aging.

Published: January 2023

Abstract: Effect of Plumbing System in Construction plays an important role. Pipe damage and defects are part of pipe maintenance. There is no chance or short circuit during Plumbing maintenance. Plumbing and plumbing involves various components that should be examined, so there is a chance that one or the other component may break. These components can cause some temporary problems as well as long-term structural damage due to water seeping into walls and floors. To avoid such problems, it is important to fix plumbing problems as soon as they are discovered. The durability of the pipe system depends on the quality of its parts and the installation skills of the installers. No plumbing system, however well designed, can be expected to operate safely or hygienically unless the products or materials used are satisfactory. The opposite is also true if the best quality products or materials are used but incorrectly installed, the system will fail. Therefore, proper research and its operation will ensure optimal success and satisfactorily meet the expectations of Effect of Plumbing System in Construction. The efficiency and quality of plumbing depends on the expectations of the home owner, the condition of the pipe work performed and its plumbing activities.

Authors: Ren Xinxin , hu xiaoyu , Qiao Shushan
Published: January 2023

In this letter, an ultra-low-power power-on-reset circuit with
reconfigurable trip-voltages is proposed. In order to reduce area and
power consumption overhead, an all-MOS sub-threshold architecture based
on threshold difference voltage references and current comparator is
designed. By configuring the reference current and the different
threshold transistors, the different trig voltages are generated to
detect multi-supply voltages. Simulation results based on 55 nm CMOS
process show that the proposed power-on-reset circuit generates trip
voltages of 385.5 mV and 775.4 mV, consuming only 8.5 nA and 92.6 nA at
the supply voltage of 0.5 V and 1 V, respectively. And the area of the
proposed power-on-reset circuit is as low as 240 μm.

The impact of the Covid-19 pandemic on the world of work has been both devastating and far-reaching. In order to reduce the unemployment rate, it is necessary to increase motivation and incentives to look for a job, to improve readiness for work and help to find a suitable job, as well as to expand employment opportunities. Public employment services have become an important point for jobseekers, giving workers and employers access to a number of passive and active labour market support mechanisms. Active labour market policies are a key tool through which welfare states seek to improve the employment prospects of the unemployed. Ongoing monitoring and evaluation of the impact of active labour market policies and programs are needed to strengthen the effectiveness and efficiency of policies in responding to the needs of different groups. This study analyzes the data obtained from the survey of the unemployed with the aim of finding out how actively the unemployed cooperate with the state employment service and use services offered by it, as well as to reveal the possible shortcomings and shortcomings of this society, so that it is possible to eliminate them and increase the efficiency of this cooperation.
Financial platforms as alternative financial instrument to crediting in Europe
Authors:   Latvia University of Life Sciences and Technologies, Mazure Gunita
Published: January 2023

The significance of financial technologies constantly grows as they have become a part of national economies. Sharing economy or alternative financing includes various digital financial activities outside the traditional banking system like crowdfunding, peer-to-peer lending and other alternatives. The research aim is to evaluate alternative finance trends in Europe. The research results show that peer-to-peer platforms mainly ensuring a high return rate have recently become very popular allowing to invest resources in various projects including real estate, loans, invoice trading and businesses. The main significant drawback of these platforms is that they are risky. The alternative finance market volumes continue to increase steadily year by year reaching USD 22.60 billion in 2020 and the United Kingdom has the largest market share of 59.35% (USD 12.6 billion) in 2020. At the beginning of 2022, there are 315 alternative finance platforms in Europe, the largest number of alternative finance platforms operate in the UK, and peer-to-peer lending (both consumer and business) and invoice trading are three the most widespread types of alternative finance in Europe covering 68% of the entire market size. The rest types of alternative finance occupy considerably lower market shares, i.e. 3-7% each. The decrease in P2P lending volumes in 2020 might be directly related with the Covid pandemic and change in consumer priorities; though, the dynamics of P2P business lending shows a constant moderate increase in the lending volumes.

Authors: Papiashvili Tatiana , Ghlonti Giorgi , Koberidze Khatia
Published: January 2023

The business provides many alternatives, and an investor-entrepreneur has always to make a decision on how best to use his fund. The first challenge for a potential investor is that the business environment is constantly changing, becoming more complex. The process of data acquisition and subsequent information generation is continuously cyclical, time and cost consuming. The second challenge is analytics. The typical small business owner makes decisions by trial-and-error. In today's data-driven AI-first environment to make frequent and quick strategic, tactical, and operational decisions, the owner/entrepreneur needs advice and guidance on startup specific issues, which should only be provided by professional experts. The goal of this research is to elaborate a theoretical foundation of an information support model for a startup – the Startup-Information-Support Model (SISM). The study uses a deep theoretical study - a qualitative method - by applying content analysis of relevant literature and primary research techniques. PESTEL and the Porter's five forces model are employed as analytical tools of expert-opinion technique. PESTEL provides a framework for information collection and data analysis at mega level, while industry attractiveness analysis is based on the Porter's five forces model. The strength of each factor (each force) is analyzed through well-defined concrete indicators, and then is measured by scoring their values. Finally, the SISM presents the whole portrait of attractiveness of specific industry.
The SISM equips consultant companies with an effective tool for conducting business intelligence and analytics. The companies would be able to offer additional value added to B2B services to potential investor-entrepreneurs. The Model has the potential to employing AI, which can more systematically incorporate environmental issues at both levels – mega forces and industry factors - into the monitoring process. Equipped with such tools, decision makers can perform complex simulations, test many possible scenarios, and quickly evaluate various impacts at low cost.
Giving Students a Voice: Dyslexia and Language Learning Experiences from Childhood to Adulthood in Greece
Authors: Seiradakis Emmanouela V.
Published: January 2023

This paper investigates the language learning experiences of Greek students in primary, secondary and tertiary education. Data were gathered from interviews with four students currently enrolled in higher education programs. The interviews focused on their language experiences and struggles from childhood to adulthood, teachers, peer relations and family. Data were analyzed using IPA. Findings indicate participants’ negative language learning experiences underwent changes in the course of their learning history. Their perceived struggles were more intense in primary school, yet they also had to negotiate a range of L1 and L2 obstacles in secondary and tertiary education. Teachers from the private sector emerged as the decisive factor in participants’ ability to overcome dyslexia-related difficulties and cope with the fierce competition of the Greek nationwide university entrance exams. Private sector teachers were also identified as the main factor for overcoming dyslexia-related difficulties in EFL. It is hoped that offering an account of their experiences will facilitate our understanding of dyslexia and the potential for inclusion for Greek dyslexic students across educational levels.

Aim of the current research is the investigation of the possibility of installing floating photovoltaics in the existing water reservoirs in the island of Crete, Greece. Data on existing water dams in Crete were used and the nominal power of floating photovoltaics as well as their potential for electricity generation were evaluated. It has been estimated that the nominal power of floating photovoltaics that can be installed in these water dams, with coverage ratio at 0.1 to 0.3, varies between 55.76 MWp to 167.3 MWp while the annual electricity generation from the floating photovoltaics varies between 78.3 GWh to 234.9 GWh. The annual electricity generation from the abovementioned floating panels corresponds at 2.57 % to 7.72 % of the annual electricity consumption in Crete in 2018. Our study indicates that floating solar photovoltaics can be installed in the existing water dams in Crete generating significant amounts of green electricity having also various environmental co-benefits. The current work could be useful to policy makers, local and regional authorities, energy companies as well as to owners of the water dams in the island.
Writing Memos: A Vital Classic Grounded Theory Task
Authors: Chametzky Barry
Published: January 2023

The process of writing and sorting memos is an important and indeed vital component of doing a classic grounded theory study. Writing memos allows a researcher to move from description to richer, more mature memos ultimately ending with a sophisticated, rich, conceptual, multivariate theory. Memos are compared one with another through a method called constant comparison. Any heretofore unknown connections are established during the comparison and sorting process. These connections develop and become increasingly conceptual during the entire memoing process. Through the entire mandatory process of writing and sorting memos that have been presented in many works of Glaser, the problem is that it is still misunderstood by novice researchers who have not experienced such a process and who are more accustomed to various analytic procedures common in qualitative data analysis. In this methodological paper, I will take the reader broadly through the memo process to present and further elucidate this important and sometimes confusing tenet of classic grounded theory. The purpose of this methodological paper is to provide explanations regarding the memo process in classic grounded theory.

Metode i postupci upravljanja komunalnim otpadom u Srbiji baziraju se na njegovom deponovanju.Ovakav način upravljanja otpadom u budućnosti će predstavljati značajan ekološki problem prvenstveno zbog proizvodnje gasova sa efektom staklene bašte i upravljanja energetskim resursima.Najveći deo ovako deponovanog komunalnog čvrstog otpada sastoji se od biorazgradivih komponenti. Zbog toga se u razvijenim ekonomijama sveta uvode nove tehnologije za upravljanje komunalnim otpadom koje uključuju savremenu reciklažu, kompostiranje i biološki tretman anaerobnom digestijom.U ovom radu analizirani su tehno-ekonomski uslovi kao i mogućnosti izgradnje MBT postrojenja koje bi predstavljalo rešenje složenog problema upravljanja otpadom u gradu Kraljevu. Posebno je ukazano na prednosti koje MBT postrojenja donose u oblasti zaštite životne sredine i racionalnog trošenja prirodnih resursa. Osnovna ideja ovog rada je da MBT postrojenje istovremeno realizuje proizvodnju energije i da se njegovom izgradnjom rešava  štetan ekološki efekat otpada u gradu Kraljevu. Da bi se došlo do kvalitenog idejnog rešenja koje bi moglo da odgovori izazovima upravljanja otpadom u Kraljevu, sprovedena je detaljna analiza dobre prakse u primerima postojećih rešenja postrojenja za mehaničko - biološki tretman komunalnog otpada.Zbog specifične dinamike generisanja otpada i njegove morfološke kompozicije za grad Kraljevo predloženo je i idejno rešenje ovakvog MBT postrojenja.Po svojoj koncepciji i kapacitetu ovim rešenjem u potpunosti bi se zadovoljile potrebe grada Kraljeva. Na osnovu ekonomske analize ove investicije zaključeno je da bi realizacija ovog objekta sa svojim energetskim, ekonomskim i ekološkim dobicima bila ekološki održiva ideja. Takvo rešenje imalo bi značajan uticaj na poboljšanje životne sredine i upravljanje strateškim resursima u gradu Kraljevu i šire.

U ovom istraživanju analiziran je kvalitet livenog termobaričnog PBX eksploziva u zavisnosti od procesnih uslova. Termobarična eksplozivna smeša na bazi oktogena, amonijum perhlorata, aluminijuma, magnezijuma i termoumrežavajućeg polimernog veziva, pripremljena je u šaržnom mikseru i izlivena su dva seta uzoraka. Jedna grupa uzoraka umrežavana je kontinuirano tokom 5 dana na temperaturi 70°C, a druga grupa je umrežavana na režimu 12 sati umrežavanja na 70°C /12 sati spontanog hladjenja, takođe tokom 5 dana. Porast viskoziteta s vremenom posmatran je tokom 90 minuta nakon homogenizacije smeše. Nakon umrežavanja određena je brzina detonacije, gustina umreženih uzoraka, mehanička svojstva testom jednoosnog zatezanja, i izvršena je FTIR analiza radi praćenja kinetike reakcije. U početku umrežavanja, razlika u kinetici reakcije umrežavanja bila je izražena, ali na kraju poslednjeg dana umrežavanja FTIR krive su izjednačene, što znači da je umrežavanje završeno. Gustine i brzine detonacije bile su približno istih vrednosti za uzorke um-režavane na oba režima. Zatezna svojstva su se razlikovala: uzorci umrežavani kontinuirano pokazali su bolju zateznu čvrstoću. Dobijeni rezultati ukazuju da, ukoliko iz nekih razloga tokom proizvodnje nije moguće obezbediti kontinuirano umrežavanje, dobar kvalitet PBX može da se postigne i sa intervalima bez zagrevanja, ali da bi se postigla zahtevna mehanička svojstva, neophodno je umrežavanje bez prekidanja

Mogućnost umrežavanja makromolekula i konformaciona promenljivost lanaca spadaju u bazna svojstva, ne samo polimerne strukture, već molekulskog sveta uopšte. Elastične mreže su dugo privlačile pažnju relativno uskih krugova inženjera koji su se bavili proučavanjem proizvoda od gume. Savremeno dizajniranje bio-kompozitnih materijala, ne može se zamisliti bez polimernih mreža. Sa druge strane, elastične polimerne mreže kao primarne strukturne jedinice postaju predmet pažnje u naučnim disciplinama u kojima ranije nisu pominjane, kao što su medicina i biohemija, a dobijaju zasluženo mesto i u nizu drugih disciplina srodnih nauci o materijalima.

Proper operation of Critical Infrastructure (CI) is by definition of high importance for a region, nation or even several countries connected in some way. The term and idea of Critical Infrastructure Protection (CIP) has to do with the preparedness and response to serious incidents that might influence the operation of CI. In Europe, the European Programme for Critical Infrastructure Protection (EPCIP) refers to the doctrine or specific programs created as a result of the European Commission’s directive EU COM(2006) 786 which designates European critical infrastructure that, in case of fault, incident, or attack, could impact both the country where it is hosted and at least one other European Member State. Member states are obliged to adopt the 2006 directive into their national statutes. [1]
Zakonska regulativa i standardizacija u oblasti merenja prirodnog gasa
Authors: Cvetković Mileva
Published: January 2023

U aprilu 2021. godini donet je Zakon o izmenama i dopunama Zakona o energetici [1] i još dva zakona iz oblasti energetike: Zakon o korišćenju obnovljivih izvora energije [2] i Zakon o energetskoj efikasnosti i racionalnoj upotrebi energije [3]. Do tada pojam „napredni merni sistemi” ili kako se negde koristi izraz „pametni sistemi za merenje” nije bio prepoznat u domaćoj regulativi, iako je ovaj termin uključujući i termine pametne ili napredne mreže, u drugim državama definisan u zakonima koji uređuju energetiku ili češće energetsku efikasnost.
Biobased composite materials obtained from unsaturated polyester resins and waste coffee

Replacing styrene with biobased monomers to produce fully biobased unsaturated polyester resins (UPRs) turned out to be quite a challenging task. Styrene has been recognized as a hazardous and a potentially carcinogenic substance for human health. Using dimethyl itaconate as an alternative reactive diluent to styrene, which can be obtained from renewable resources, enables low viscosity for easy manipulation of mentioned UPRs. Fully biobased UPRs in question were based on itaconic acid, succinic acid, and propylene glycol, which were then diluted with dimethyl itaconate. Having in mind that UPRs can be used as a matrix for composite materials, this paper examines the effect of different weight ratios of spent coffee grounds as a filler. To determine the application of thus obtained composite materials, characterization consisted of examining mechanical properties based on viscosity measurements, uniaxial stretching experiments, FTIR spectroscopy and gel content analysis.
