Simulation of Shotcrete in RC Tunnel Using Finite Element Method
Authors: Tuhta Sertaç
Published: July 2023

Nowadays, tunnels are gaining importance with the developing transportation networks. Different solutions are made in the design of tunnels according to the land structure and ground condition. Various retrofitting methods are used in damaged tunnels. Especially in recent years, natural disasters in the world have also affected the tunnels. There may be damage and collapse in the tunnels during and after the disaster. It is predicted that in the event of a possible collapse in the event of a disaster, loss of life and property may also occur. After the disaster, even if the tunnels have not collapsed, they are damaged. In this case, collapse may occur in the next disaster due to collapse or environmental vibrations. It is also known that in post-disaster situations, it is vital that the transportation network remains active in order to deliver the necessary aid to the region. For all these reasons, in this study, the shotcrete method, which is one of the retrofitting methods of tunnels, is mentioned. Thus, the effect of the shotcrete method applied on an exemplary tunnel on modal parameters has been demonstrated. In this comparative study, it was observed that the stiffness of the tunnel increased with the shotcrete method. As a result of this study, it is suggested to retrofitting the tunnels with the shotcrete method, taking into account the state of the tunnel lining or mirror and environmental factors.

Authors: Khan Ameer Hamza , Sajid Dr. Muhammad , Ahmed Rohail
Published: July 2023

The objective of the study was to create a fuzzy logic-based cost modelling system for the sugar industry in order to comprehend the impacts of sugar cost determinants on total cost. The designed system takes into account variables such as fluctuating cane prices, cane weight, distribution distances, and crushing cessation. The data is collected from the cost statements of various Pakistani sugar refineries. The primary research objective was to determine the effects of the unpredictability of various cost variables on the ultimate price of sugar. The cost determinants were deemed input variables, while the cost of sugar production was considered an output variable. The cost variables were categorised as follows: cost of basic materials, cost of distribution, cost of labour, cost of operations, factory overheads, and crushing cessation (losses). The Mamdani Fuzzy Inference system was used to analyse the data. To develop the system, 729 fuzzy rules and three levels of fuzzy sets were created. The developed fuzzy logic-based system is able to evaluate the sugar cost structure and take uncertainty factors into account. Consequently, a significant contribution of the developed system is the provision of heuristic principles that facilitate the selection of cost-effective outcomes.

Published: July 2023

One of the main tectonic belts in Türkiye is the Taurus Orogenic Belt, where significant bauxite mineralizations are observed. The bauxite deposits in Doğanşehir (Malatya, Türkiye) occur as massive bodies and lenses within the carbonate rocks of the Permian-Triassic Malatya Metamorphics in the Eastern Taurus Orogenic Belt. The region’s geological foundation comprises lithologies belonging to the Malatya Metamorphics. This unit consists primarily of schists, calc-schists, and marble, which are overlain by the Late Cretaceous-Eocene Berit Metaophiolite, Eocene Maden Complex, Early-Middle Eocene Doğanşehir Granitoid, and Plio-Quaternary cover sedimentary units. Oolitic and pisolitic bauxite mineralizations are present within the Permian-Triassic carbonate rocks (Malatya Metamorphics). These mineralizations occur in carbonate rocks that contain fossils and are observed in the form of lenses. The bauxite lenses are overlain by relatively thin, middle-layered Permian-Triassic carbonate rocks (Malatya Metamorphics). With the advancement of technology, Scanning Electron Microscopy (SEM) has been used for the analysis of bauxite ores to determine the presence of elements within their crystal lattice structure. The point analysis and mapping method were employed to identify the elements that could be present within the crystal lattice structure of the bauxite ores. The SEM analysis of the samples using the mapping method revealed the distribution of Fe, Ti, Si, Al, and O elements before and after activation. The images indicate that bauxite exhibits a broad grain distribution, both below and above 50 um. The elemental spectrum diagram shows the presence of O, Al, and Si in the sample. Additionally, Fe, Ti, C, K, and Mg were also detected. Using SEM analysis of the same samples and the mapping method, the distribution of Fe, Ti, Si, Al, and O elements in the structure was examined before and after activation. As seen from the images, the elements Al, O, and Si exhibit high density in certain areas before activationshow a more homogeneous distribution and similar structures after activation. Fe, Mg, and K display a similar distribution pattern, while Ti and C exhibit different characteristics.

Published: July 2023

This paper aims to solve one of the energy issues using specific new building designs using the building-integrated photovoltaic (BIPV) panels as a double skin envelope. The BIPV system can be an innovative material for the building envelope during the design process as a: frame component, curtain wall or shading device. In addition to its power generation, the use of the BIPV can be an integrated part of the design of future envelopes and in the energy renovation of old buildings; these systems can producerenewable energy, minimize energy consumption, provide adequate indoor comfort and have less impact on the environment. As an external envelope of the buildings and a source of energy, the BIPV systems can represent the architectural appearance and aesthetic arrangements of the future building. Our investigation is based on an Energy report in many existing office buildings in a hot arid region of Algeria in order to assess their energy consumption, thereafter; calculate the energy yield after the BIPV hypothetical use in building architecture. The important result shows that the BIPV system enhances energy consumption with different percentages of the total energy consumption per year (Building sample 1: 50%, Building sample 2: 30% and Building sample 3: 65%) this is due to many architectural elements; such as: envelop form, shading devices, opening ratio, and environment masks. The major conclusion of the research reveals that The BIPV systems can preserve the architectural aesthetic appearance as well as enhancement of energy consumption.
Fluoride and Liver Toxicity: A Zebrafish Model
Authors: MAMMADZADA Laman , TORAMAN Emine
Published: July 2023

Fluoride, which is exposed by living organisms through food and water intake, causes many health problems. The liver is one of the organs most affected by sodium fluoride (NaF) toxicity. Studies have shown that NaF causes many pathological and metabolic changes in the liver. Many studies have shown that exposure to high fluoride concentrations in drinking water elevates the levels of kidney and liver function enzymes in serum and causes severe histological changes in the liver and kidneys. However, there are limited studies on the liver toxicity of chronic fluoride intake in amounts close to daily usage doses. Therefore, in our study, the effect of chronic fluoride (NaF) exposure at low doses on zebrafish liver toxicity was investigated. Liver tissues of zebrafish exposed to NaF at doses of 1.5 ppm, 5 ppm, and 100 ppm for 6 weeks were used in the study. GSH and MDA levels were measured in these tissues. In addition, specific activities of GST and GR enzymes were determined. When the data obtained were examined, it was observed that while GST, GR, and GSH levels decreased, MDA levels increased, especially in the groups treated with 5 and 100 ppm NaF. This suggests that chronic exposure to fluoride, albeit at low doses, may be a risk factor.

Simulations of Solving a Single-Player Memory Card Game with Several Implementations of a Human-Like Thinking Computer Algorithm
Authors: Végh Ladislav , Takáč Ondrej
Published: July 2023

The memory card game is a game that probably everyone played in childhood. The game consists of npairs of playing cards, whereas each card of a pair is identical. At the beginning of the game, the deck of cards is shuffled and laid face down. In every move of the game, the player flips over two cards. If the cards match, the pair of cards is removed from the game; otherwise, the cards are flipped back over. The game ends when all pairs of cards have been found. The game could be played by one, two, or more players. First, this paper shows an optimal algorithm for solving a single-player memory card game. In the algorithm, we defined four steps where the user needed to remember the earlier shown pairs of cards, which cards were already shown, and the locations of the revealed cards. We marked the memories related to these steps as M1, M2, M3, and M4. Next, we made some simulations as we changed the M1, M2, M3, and M4 memories from no user memory (where the player does not remember the cards or pairs of cards at all) to a perfect user memory (where the player remembers every earlier shown card or pair of cards). With every memory setting, we simulated 1000 gameplays. We recorded how manycards or pairs of cards the player would need to remember and how many moves were required to finish the game. Finally, we evaluated the recorded data, illustrated the results on graphs, and drew some conclusions.

The increase in energy demand worldwide led to the excessive use of fossil fuels, thus, critical changes in the earth's climate due to its high emissions, which led to the search and the use of less polluting fuels and more sustainable such as Propane and Bio-Syngas. We have used the Chemkine code fed by the USC ver 2.0 mechanism and the Gri Mech 2.11 N sub mechanism for NOx assessment to conduct a numerical study on the flame structure and NOx emissions characterisation of the Propane syngas mixture diffusion flame. It was found that rich-Syngase mixtures flames generate high flame temperatures, thus high NO emissions. In contrast, rich-Propane mixture flames generate low flame temperatures, thus high NO2 emissions.

In this above scientific work, data are given on the presence of microorganisms (main bacteria) and heavy metals present in the underground layers of the Elbasan city, located in Middle Albania. From the data obtained, we can reach an important conclusion, if the presence of bacteria and heavy metals is present at such levels that they can be considered as soil pollution factors.The primary purpose of undertaking this work was to present the possible connection between microbial and chemical soil pollution, pollution which has a serious impact on the population’s health.To complete this goal, five soil samples that were taken up to a depth of 0.5 m, in April 2023, were served. We emphasize the fact that Elbasan city has been considered over the years as an area with significant atmospheric chemical and microbiological pollution.From the statistical processing of the data, we obtained results that present data on chemical elements that can be considered as a possible factor of soil pollution.In conclusion, starting from the qualitative analysis of the results by comparing them with the allowed pollution rates from the EU, we find a chemical pollution of the soil from the element nickel, which is present in an amount about 2.5 times more than the standards defined by the Regulatory Acts of EU.We are of the opinion that the ascertained pollution of the Elbasani soil is mainly dedicated to the activity of agricultural farmers in the misuse of organic and chemical fertilizers, the mismanagement of wastewater by the relevant city authorities, and mainly to the abusive activity of light and heavy industries that operate in the city.

Rad nastoji rekonstruirati „sagu“ o osmanskom pokušaju „vrbovanja“ Nikole Šubića Zrinskoga tijekom 1553./1554. godine, fragmentarno razlomljenu u Vrančićevim špijunskim pismima iz Carigrada i staviti je u mogući povijesni kontekst. Dok kralj Ferdinand nije bio upoznat s pokušajem „vrbovanja“ Zrinskoga, određene činjenice upućuju na distanciranje Zrinskoga od kralja. Nakon 15. travnja 1554. godine, kada je kralj znao da pokušaj „vrbovanja“ Zrinskoga traje, određene činjenice upućuju na ponovno zbližavanje kralja i Zrinskoga, a možda je upravo spomenuta „saga“ uzrok toj kraljevoj politici popuštanja prema Zrinskom.

Starija dob period je brojnih promjena na tjelesnom, kognitivnom, emocionalnom i socijalnom planu, ali unatoč gubicima postoje i pozitivne promjene. U Republici Hrvatskoj je u srpnju 2022. godine bilo ukupno 1.230.173 korisnika mirovina. S obzirom na to da se radi o značajnom udjelu u ukupnom stanovništvu RH, cilj istraživanja bio je proučiti subjektivne čimbenike uspješnog starenja, odnosno utvrditi u kojem smjeru je potrebno razvijati intervencije zbog poboljšanja kvalitete njihovog života. U istraživanju je sudjelovalo 274 umirovljenika, od čega 182 žena (66,4%) te 92 muškaraca (33,6%) prosječne dobi 70 godina (SD=8,5) koji su u prosjeku umirovljeni s oko 55 godina (SD=7,98). Od standardiziranih upitnika, korišteni su: Skala samoprocjene uspješnog starenja, Kratka forma UCLA-skale usamljenosti, Gerijatrijska skala depresije: kratka forma te Upitnik emocionalnih vještina i kompetencija. Sudionici su upitnik ispunjavali uživo nakon što su potpisali informirani pristanak i suglasnost za sudjelovanje. Sukladno očekivanjima, većina varijabli umjereno je do srednje pozitivno povezana, uz iznimku kronološke dobi koja je značajno povezana samo sa subjektivnom dobi (r=0,553). Sukladno rezultatima, osobe koje se percipiraju mlađima od svoje objektivne dobi iskazuju manje depresivnih simptoma i bolje emocionalno funkcioniranje, a vlastito starenje procjenjuju uspješnijim. Dobivena je umjerena i pozitivna povezanost usamljenosti i depresivnosti (r=0,392) te niska, negativna povezanost usamljenosti i emocionalne kompetencije (r=-0,187). Starije osobe koje imaju razvijeniju emocionalnu inteligenciju iskazuju nižu razinu depresivnosti (r=-0,336). Konačno, model koji kombinira varijable spola i subjektivne dobi u prvom koraku te varijable depresije, usamljenosti i emocionalnih kompetencija u drugome koraku pokazao se statistički značajan te objasnio gotovo polovicu varijance uspješnog starenja, odnosno 45,3% (R2c= 0,442). Preporuke za buduća istraživanja idu u smjeru kombiniranog nacrta istraživanja s minimalno dvjema točkama mjerenja, gdje bi se mogle uključiti i objektivne mjere poput zdravstvenog statusa ili visine mirovine, uz razmatranje mogućnosti korištenja reprezentativnijeg uzorka.

"My Data Model Is JSON"
Authors: Winston Donny
Published: July 2023

“My data model is JSON”. JSON is not a data model. JSON has no semantics in the context of information systems; JSON defines neither how data “behaves” nor how machines can compute with it. “My data is just JSON”. Your data is never just JSON; you always impose external semantics. “JSON is easy to understand”. What does the field "harrastukset" mean?

Indexing Validators

Published: July 2023

Why would one consider indexing validators? Reuse. The value of reuse seems obvious for structural and semantic  specification  , i.e. schemas and controlled vocabularies – there is opportunity to perceive two datasets as aligned.
Who Validates the Validators?

Given a fip:Metadata-schema and a validator for it, such as a sh:Validator or a JSON Schema, how do you determine that the validator is…valid? That it speaks the desired fip:Knowledge-representation-language, that it knows all the terms in a desired fip:Structured-vocabulary and checks their usage against a desired fip:Semantic-model? In other words, that it adheres to a doap:Specification? I do not know.
Finding citations of specimens
Authors: Page Roderic
Published: July 2023

Note to self. The challenge of finding specimen citations in papers keeps coming around. It seems that this is basically the same problem as finding citations to papers, and can be approached in much the same way. If you want to build a database of reference from scratch, one way is to scrape citations from papers (e.g., from the "literature cited" section), convert those strings into structured data, and add those to your database.
Tracing Identifiers
Authors: Winston Donny
Published: July 2023

At a base level, an identifier is simple to trace – it is the sequence (modulo concurrency) of assertions of which it is a part. In fact, this can be the basis for tracing the representation of a “thing” as the flock of relationships between identifiers, i.e. metadata, that waxes and wanes in association with “the” identifier of the thing.
The Handle System of Persistent Identifiers
Authors: Winston Donny
Published: July 2023

The Handle system is a popular choice for the assignment and resolution of globally unique, persistent identifiers. Governance is centralized with the DONA Foundation, and administration is distributed among so-called Credentialed Multi-Primary Administrators (MPAs), of which there are currently nine. You’ve likely heard of at least one MPA: the International DOI Foundation. Each MPA is assigned a number.

This guest post by Tony Rees describes his quest to track all genus names ever published (plus a subset of the species…). A “holy grail” for biodiversity informatics is a suitably quality controlled, human- and machine-queryable list of all the world’s species, preferably arranged in a suitable taxonomic hierarchy such as kingdom-phylum-class-order-family-genus or other.

Silent Conversations: Goals of Care and End-of-Life Quality in Relapsed High-Risk Leukemia
Authors: Graham, DNP, APRN-C Lacy Jo , Hite, DNP, APRN-C Amy , Harris, PhD, FNP-C Jennifer , Belcher, PhD Greg
Published: July 2023

Background: Advanced practice providers (APPs) affect high-quality health care through leadership, evidence-based practice implementation, and quality improvement projects. When planning solutions to clinical problems, leadership must solicit APP input to promote success. Hematology patients are more likely to receive poor-quality end-of-life (EOL) care than those with solid tumors. Regardless of disease, aggressive EOL care is increasing despite evidence that it is often inconsistent with patients’ goals of care (GOC). Data regarding this phenomenon in hematology specifically is lacking. The distorted association of “end of life” with “goals of care” has “silenced” crucial goals discussions in patients with relapsed or refractory high-risk leukemia, which raises concerns for the provision of care that is inconsistent with patients’ values and preferences. Hematologists may possess certain traits and distinct barriers leading to what one might call an aversion to GOC discussions in the inpatient setting. Aims: (1) Quantify hematologists’ rate of participation in a GOC pathway initiative during two separate months. (2) Explore the hematologists’ definition of and barriers to having GOC discussions. Design: This is a mixed-methods, explanatory sequential design (follow-up explanations variant). Sample: Quantitative: Hematology inpatient admissions during two nonconsecutive months in 2021. Qualitative: Eighteen leukemia hematologists from one dedicated cancer center. Results: During the 2 months, an average of 36% of admissions met the criteria for GOC pathway initiation, 19% of those had an appropriate initiation order, and < 1% had a properly documented and billed GOC discussion. Nine hematologists responded to a SurveyMonkey poll with two questions. All nine included clinical situation and communication in their definition of GOC discussions. Time limitations and prognostic uncertainty were the two most reported barriers. Discussion: The findings demonstrate that the apprehension of hematologists to have GOC conversations is similarly seen in the APPs’ reluctance to initiate a pathway intended to lead to GOC conversations. The percentage of eligible inpatient admissions meeting the specified criteria was similar between the 2 months; however, the number of appropriate referrals and documented or billed GOC discussions was higher in the earlier month, demonstrating temporal decline. Further research inquiry is needed to explore causation of this phenomenon.
Managing Drug Interactions With Oral Anticancer Treatments

Published: July 2023

The use of oral anticancer treatments is widespread and vital to modern cancer treatment. Novel oral chemotherapy and targeted therapy treatments continue to receive US Food and Drug Administration approval every year, making knowledge of these agents a necessity for practitioners working in oncology. Many oral anticancer agents are prone to drug interactions that can contribute to adverse effects and decrease therapy efficacy. Potential drug-drug interactions include (1) interactions with CYP3A4 inhibitors and inducers, (2) interactions related to gastric acid suppression, (3) interactions related to prolongation of the cardiac QT interval, (4) interactions related to anticoagulant medications, and (5) drug-food and drug-herb interactions. Identifying potential drug interactions and appropriately managing them is key to preventing adverse effects and ensuring maximum efficacy while on oral anticancer therapy. Management of adverse effects increases patient compliance, ensures medication safety, and allows patients to remain on therapy. This article discusses the mechanisms of interactions and types of interacting medications. Specific recommendations are discussed.
