Effects of coconut fibers on flexural and tensile strengths of concrete maintaining uniform workability
Authors: Abbasi Muhammad Farhan , Palari Sarfaraz Ahmed , Shaikh Fahad Ali 
Published: October 2024

Concrete, the most commonly utilized building material, possesses a high compressive strength but has very low tensile and flexural strength. Steel is the most popular type of flexural and tensile strength enhancer in Cement concrete, however due to the rapid increase in the cost of steel as a result of the financial crises experienced in several countries, research is currently being done to use other affordable and easily accessible material to decrease the quantity of reinforcement steel, as Tensile as well as flexural reinforcement. Coconut fiber, also known as coir fiber, Due to its thread-like structure has previously been shown to help boost concrete's flexural and tensile strength, having said that it negatively affects the workability of fresh concrete. So we can use a workability enhancer to overcome this negative effect while getting optimum benefits in terms of enhancement of flexural and tensile strength. The goal of the study is to discover how coir fiber affects concrete's flexural and tensile strength under uniform workability, with the help of a super plasticizer. It also attempts to find the ideal content of fiber to be used in concrete. The methodology is that with the assistance of a hit-and-trail procedure, we find out the amount of plasticizer needed for each fraction of fiber percentage, to create a constant range workability of 40±5mm for every proportion. Beams and cylinders were cast, curing was done for 28 days, and then their flexural capacity and tensile strength were analysed for each fraction of coconut fiber: 0%,0.4%,0.8%,and1% (by WT of cement )in comparison to plain concrete, the flexural strength improved by 21 percent,25 percent,and15.24 percent at fibers proportions of 0.4%, 0.8%, and 1%, respective, while the tensile strength increased by 29.66 percent, 38.66 percent, and 22.81percent. The best outcomes were discovered at 0.8%. It's determined that the addition of coir fiber results in a considerable improvement in flexural strength and Tensile strength meanwhile plasticizer proves to be good cure against workability loss due to fibers.

Published: October 2024

It is essential for students to plan their careers because selecting the right career path shapes a person’s life. In such disciplines as computer science, information technology, and software engineering, assisting students toward appropriate employment is even more helpful. Thus, throughout the student’s education, they must evaluate their strengths to determine which professional sector corresponds to their abilities. It is for this reason that this research introduces an intelligencebased career recommendation system that will incorporate the analysis of such factors as the student’s academic performance, economic status, and demographic features to use data mining models in determining the best prospective career path to offer the student a more transparent and more informed vision and course to set on in the future. Three key aspects were addressed: first, one or another model and classifier for assessing the impact of pre-university education on the choice of a profession and, consequently, the selection of technologies were used. Second, these models accurately forecast students' careers using core courses, CGPA, and FYP data. Third, socioeconomic or demographic data was incorporated into the prediction to make it more accurate. Regarding the method of class distribution balancing, the Synthetic Minority Oversampling Technique (SMOTE) approach was used. The study reveals that variables specifying preuniversity education directly impact students’ career choices and that, employing data mining techniques, career choices could be forecasted considering academic performance and other related factors.
The Impact of a New Container Port on the Greenhouse Gas Pollution
Authors: Bogataj David , Campuzano-Bolarin Francisco , Nicolás José Andrés Moreno 
Published: October 2024

Abstract

Background
Large vessels that call at European ports will have to pay for their CO2 emissions from transporting cargo that enters or goes from a European port since January 2024. The costs will increase with increasing global trade. This results in a higher pollution level, including greenhouse gas (GHG) emissions like CO2.

Methods/ Approach
Based on the gravity model embedded in a global supply chain, we developed a model to evaluate maritime transport pollution in case a new, sufficiently large container port becomes operational. Additionally, we consider how lousy railway connections to European customers increase transportation costs and pollution.

Results
The approach to the well-connected sequences of gravity models in the intercontinental maritime chains evaluates the differences in quantities of cargo between ports when a new port is opened, and the waiting time does not change. We also highlight that poor rail connections can reduce this positive effect.

Conclusions
We showed how it is possible to estimate the optimal capacity of a new port with a multi-level gravity model and how this would affect the pollution around the port and on the routes from the port to the final consumers.
Selection Procedure of the Approximation Methods for Deriving Priorities: A Case of Inconsistent Pairwise Comparisons
Authors: Čančer Vesna 
Published: October 2024

Abstract

Background
When pairwise comparisons are used to express preferences for alternatives or judgments on criteria's importance, several methods can be used to derive priorities in multi-criteria decision-making. In the case of inconsistency, different methods give different results.

Objectives
The main goal of this paper is to present the procedure of measuring the accuracy of the selected approximation methods based on pairwise comparisons compared to the priorities obtained by the eigenvalue method. It also aims to illustrate the procedure on the numerical example characterised by acceptable inconsistency.

Methods/Approach
The presented procedure is based on a prescriptive approach, the fixed ratio scale, reciprocal pairwise comparison matrices, and consistency ratio. Mean absolute deviation and mean absolute percentage deviation are used to measure accuracy.

Results
The first result is the theoretical statement of the priorities’ accuracy measurement procedure. The results of the numerical example characterised by the preferences of strength slight to strong plus show that, on average, the most accurate approximation method is the geometric mean method.

Conclusions
The research contributes to the literature on prescriptive approaches to decision-making. The results can show potential users which approximation method to use and lecturers which of them to include in the curriculum portfolio.
Strategic Categorization of Dairy Cow Farms in Croatia using Cluster Analysis
Authors: Petrač Maja , Zmaić Krunoslav , Žgajnar Jaka 
Published: October 2024

Abstract

Background
The milk processing sector in the Republic of Croatia faces numerous challenges. It is a distinctly bipolar structure, with some entities resembling the largest milk producers in the EU, while many small and medium-sized dairy farms struggle to remain competitive and achieve further progress. To formulate effective policy, it is important to differentiate between these types and address their key challenges.

Objectives
The aim is to find the most representative solution that will help us define typical dairy farms and upgrade a SiTFarm tool (Slovenian Typical Farm Model), enabling us to assess the situation in Croatia comprehensively.

Methods/Approach
Cluster analysis was conducted using empirical data obtained from the Croatian Agency for Agriculture and Food. The analysis involved applying both hierarchical and non-hierarchical clustering techniques.

Results
Two cluster analysis scenarios are presented, differing in the variables used. In each scenario, 16 relatively homogeneous clusters of farms were obtained. Diversity was minimized within these clusters, and they effectively explain the dairy business in Croatia.

Conclusions
The results of this analysis thus represent an important starting point for further analysis of the dairy sector in Croatia. These findings could help policymakers identify the types of farms that would benefit most from targeted investments to enhance efficiency, economic viability, and environmental sustainability.

Published: October 2024

Abstract
In recent years, the demand for innovative, sustainable, and efficient food packaging solutions has surged in response to growing concerns about environmental impact, food safety, and quality preservation. A sericin-based polymer composite film with multifunctional properties shows promise as an alternative for enhancing food packaging. In this study, sericin-based composite films were prepared by incorporating Aloe vera gel, chitosan, and glycerol into a sericin solution (1.5 % w/v) through facile homogenisation at 70 °C, followed by casting and subsequent drying on a glass platform. The resulting dried film exhibited uniformity, a smooth texture, and successful integration of the composite components. The film demonstrated a moisture content of 21.02 % and a porosity of 3.56 %, with a thickness of (62.1 ± 2.3) µm. It exhibited moderate transparency with reasonable water vapour permeability. Notably, the DPPH scavenging results indicated that the film has a potent antioxidant capacity with an efficacy rate of 99.1 %, supported further by a phenolic content of 11.5 mg GAE per gram of film. Controlled solute migration of components from the composite films was observed, particularly under acidic conditions. Importantly, toxicity evaluation on A549 cells revealed no adverse effects, even at higher concentrations. Due to its consistent film-forming ability, antioxidant potency, controlled migration, and safe nature, the developed sericin polymer-based film could be an effective alternative for food packaging sensitive foods, maintaining oxidative stability, reducing moisture loss, improving quality, and extending shelf life.

Penelitian ini bertujuan menganalisis pengetahuan dan sikap civitas academica tentang kekerasan seksual dan peran perguruan tinggi untuk mencegah dan menanganinya. Data dikumpulkan melalui kuesioner online di perguruan tinggi negeri berbadan hukum (PTN-BH) dengan inisial PT X dan perguruan tinggi negeri tidak berbadan hukum (PT Y). Responden berjumlah 238 orang, dengan proporsi dosen (25%), tenaga kependidikan (15%), dan mahasiswa (60%). Hasil penelitian tidak menunjukkan perbedaan yang signifikan di kedua jenis PTN tersebut dalam pengetahuan atau pengalaman responden tentang kekerasan seksual, sikap, dan peran perguruan tinggi dalam pencegahan dan penanganan kekerasan seksual. Mayoritas responden pernah pengalami kekerasan seksual verbal yaitu mendapatkan ucapan yang memuat rayuan, lelucon, dan/atau siulan yang bernuansa seksual tanpa persetujuan korban. Sikap positif ditunjukkan mayoritas responden terhadap korban, yaitu mendapatkan hak korban (melapor, mencari informasi, memberi informasi alternatif penanganan kasus) dan membantu melaporkannya kepada pihak yang berwenang di kampus. Upaya pencegahan dan penanganan kekerasan seksual di kedua perguruan tinggi juga relatif tidak berbeda, dalam bentuk pendampingan psikologis dan hukum, pelaporan, pemulihan korban secara medis, psikologis, sosial, spiritual, dan hukum, dan pengenaan sanksi administratif kepada pelaku, serta penyediaan sarana prasarana untuk menciptakan rasa aman.

Published: October 2024

Internationally, LGBTQIA+ people are at increased risk of homelessness and housing instability. Literature on this topic emerging from the Global South has been less prominent. This article explores LGBTQIA+ homelessness in Cape Town, South Africa. Cape Town is a unique local context, given the post-apartheid political landscape and prevalent negative attitudes towards LGBTQIA+ people in South Africa. Grounded in the ecological systems theory, this article explores staff perspectives about emergency shelter interventions with the population of LGBTQIA+ people experiencing homelessness. An international team of scholars coordinated this research effort to interview staff at an LGBTQIA+ focused shelter in Cape Town. Interview data were analysed using narrative analysis strategies. Results show that the shelter seeks to provide a safe and structured environment for LGBTQIA+ people who may have experienced family rejection, educational or economic challenges and mental health concerns. Researchers recommend that there be a shift in focus to macro socio-economic forces when considering LGBTQIA+ homelessness. Researchers also discuss the need for more robust social work training for staff of shelters who serve this vulnerable and resilient population.

Authors: Peng Xinrui , Wan Jiayuan , Wang Yafei , Wang Liqun 
Published: October 2024

Objective:
This study aimed to identify key factors influencing post-operative pathologic escalation in Chinese women with histologic cervical low-grade squamous intraepithelial lesions (LSILs) undergoing cervical conization and construct a predictive nomogram model.

Material and Methods:
A retrospective analysis was conducted on 107 patients with LSIL from Bengbu City, Anhui Province, China, who underwent cervical conization at the First Affiliated Hospital of Bengbu Medical College from January 2019 to January 2023. Patients were categorized into groups based on post-operative pathological upgrade. Univariate and multivariate logistic regression analyses identified independent risk factors. A nomogram model was developed and evaluated for clinical predictive ability using calibration curves, the Hosmer–Lemeshow test, and decision curve analysis (DCA).

Results:
Post-operative pathological upgrades were experienced by 39.3% of patients with LSIL. Independent risk factors for escalation included positive human papillomavirus (HPV)16/18/52/53/58 high-risk types (P < 0.05, OR = 4.95, 95% CI = 1.32–18.46), ThinPrep Cytology Test (TCT) results indicating high-grade squamous intraepithelial lesion (HSIL)/atypical squamous cells, cannot exclude a high-grade squamous intraepithelial lesion (ASC-H)/atypical glandular cells ( AGC) (P < 0.01, OR = 13.12, 95% CI = 3.10–55.50), and cervical transformation zone (TZ) type III (P < 0.05, OR = 6.10, 95% CI = 1.65–22.56). Based on these factors, the nomogram demonstrated good differentiation and calibration (area under the curve [AUC]: 0.744, 95% CI: 0.674–0.839). DCA indicated high clinical predictive value.

Conclusion:
HPV16/18/52/53/58 high-risk types, TCT HSIL/ASC-H/AGC, and colposcopic cervical TZ type III are independent risk factors for post-operative pathologic escalation in LSIL. Consideration of pre-operative HPV, TCT results, and cervical TZ type is crucial for effective triage and patient management. The constructed nomogram provides a practical tool for risk assessment of patients with LSIL undergoing cervical conization.

Published: October 2024

Background:
Giant cerebral aneurysms have a high rupture rate, are often difficult to treat, and have a poor prognosis. We report two cases in which good results were achieved with a short, two-stage operation using a combination of endovascular treatment (EVT) and direct surgery.

Case Description:
Case 1 - A 50-year-old man had become immobile due to truncal ataxia after nausea. Magnetic resonance imaging, computed tomography (CT), and angiography revealed a giant thrombosed aneurysm of the right vertebral artery 30 mm in diameter, which compressed medulla oblongata. He underwent endovascular parent artery occlusion (PAO) followed by direct surgical thrombectomy 3 days later.The patient’s outcome was modified Rankin score (mRS) 1 at 7 days after the operation and mRS 0 at 1 year. Case 2 - A 40-year-old man developed a progressive visual disturbance. CT showed a giant thrombosed aneurysm of 50 mm diameter in the C2 portion of the left internal carotid artery. A balloon test occlusion (BTO) and cerebral blood flow single-photon emission computed tomography under BTO suggested partial ischemic tolerance due to PAO. PAO followed by low flow bypass and thrombectomy of the aneurysm by direct surgery was performed on the same day.The patient’s vision was improved with the outcome of mRS 1.

Conclusion:
EVT in a short-term two-stage operation for a thrombosed giant cerebral aneurysm is effective for the purpose of hemostasis in the thrombectomy designed to decompress the suffered brain or nerve. Complete PAO and meticulous perioperative use of antithrombotic agents are necessary to avoid perforator failure and hemorrhagic complications in this technique.

Бул макалада рефлексивдик талдоонун алкагындагы адамдын руханий тажрыйбасы маселеси каралат, андан тышкары анда айтылгандай, инсандын руханий жактан жетилишинин критерийлерин белгилебесек, өз алдынча аң-сезимди өнүктүрүү ыкмаларынын натыйжалуулугун аныктоо биз үчүн кыйынга турат. Адамдын өздүк аң-сезиминин өсүү даражасын аныктоонун критерийлери жөнүндөгү маселе кыйла татаал. Бир жагынан, биз адамдын руханий тажрыйбасы субъективдүү, индивидуалдуу экендигин ырастайбыз; бирок, экинчи жагынан, биз инсандын өзүн-өзү аң-сезиминин өнүгүү даражасын жана деңгээлин көпчүлүк адамдар үчүн алгылыктуу боло турган стандарттар менен аныктоого умтулабыз. Биз адеп-ахлактык жана адеп-ахлаксыз тажрыйбанын оордук даражасы рухий жактан жеткилеңдиктин критерийи болуп калышы мүмкүн деп эсептейбиз. Бул жерде моралдык маселе ой жүгүртүү үчүн өзгөчө мааниге ээ, анткени ал субъективдүү көз караштар менен жана инсандын өздүк аң-сезиминин өнүгүү динамикасы менен тыгыз байланышта.
В данной статье рассматривается вопрос о духовном опыте человека в рамках рефлексивного анализа, кроме того, как сказано в ней, нам сложно определить эффективность методов развития самосознания, если мы не установим критерии духовного зрелость человека. Более сложен вопрос о критериях определения степени роста самосознания человека. С одной стороны, мы утверждаем, что духовный опыт человека субъективен и индивидуален; но, с другой стороны, мы стремимся определить степень и уровень развития индивидуального самосознания по стандартам, приемлемым для большинства людей. Мы считаем, что критерием духовного совершенства может стать степень тяжести нравственного и безнравственного опыта. Здесь нравственная проблема имеет особое значение для мышления, поскольку тесно связана с субъективными представлениями и динамикой развития самосознания личности.
In this article, the question of the spiritual experience of a person is considered within the framework of reflexive analysis, besides, as it is said in it, it is difficult for us to determine the effectiveness of the methods of developing self-awareness, if we do not establish criteria for the spiritual maturity of a person. A more complex question about the criteria for determining the degree of growth of a person's self-awareness. On the one hand, we claim that the spiritual experience of a person is subjective and individual; but, on the other hand, we strive to determine the degree and level of development of individual self-awareness according to standards acceptable to the majority of people. We believe that the criterion of spiritual perfection can be the degree of severity of moral and immoral experience. Here, the moral problem has a special importance for thinking, because it is closely related to subjective ideas and the dynamics of the development of self-awareness of the individual.
