Published: January 2025

Does guerrilla marketing influence perceptions of marketing innovation and brand trust? Alongside this question, the issue of whether perceptions of marketing innovation impact brand trust arose during the development of the research model and literature review. Thus, besides the main objective of the study, a secondary aim is to investigate the effect of marketing innovation perception on brand trust. To achieve these objectives, data were collected from a target audience using an online survey method within the framework of a quantitative research design. The collected data were first subjected to normality tests, followed by reliability and validity analyses of the scales. To determine the socio-demographic characteristics of the participants, frequency and percentage distributions were used, while regression analysis was employed to test the research hypotheses. Additionally, the mediating effect was tested within the proposed model framework. The study found that guerrilla marketing positively influences consumer perceptions of innovation, affects consumer purchasing decisions, and enhances brand trust. Additionally, marketing innovations were observed to have positive effects on consumer trust and perceived value. It can be stated that guerrilla marketing campaigns indirectly affect brand trust through marketing innovation, and these strategies enhance consumer trust with innovative and creative campaigns.

Abstract
Water used in post‐harvest handling and processing operations is an important risk factor for microbiological cross‐contamination of fruits, vegetables and herbs (FVH). Industrial data indicated that the fresh‐whole FVH sector is characterised by very variable operational cycle duration (between 8 and 900 h), large product volumes (e.g. more than 6000 tonnes) and process water at 2.8–25.0°C. Intervention strategies were based on water disinfection treatments, mostly using chlorine‐based disinfectants. Water replenishment was not observed within studied industries. The industrial data, which included 29 scenarios were used to develop a guidance for a water management plan (WMP) for the fresh‐whole FVH sector. A WMP aims to maintain the fit‐for‐purpose microbiological quality of the process water and consists of (a) identification of microbial hazards and hazardous events linked to process water; (b) establishment of the relationship between microbiological and physico‐chemical parameters; (c) description of preventive measures; (d) description of intervention measures, including their validation, operational monitoring and verification; and (e) record keeping and trend analysis. A predictive model was used to simulate water management outcomes, highlighting the need for water disinfection treatments to maintain the microbiological quality of the process water and the added value of water replenishment. Relying solely on water replenishment (at realistic feasible rates) does not avoid microbial accumulation in the water. Operational monitoring of the physico‐chemical parameters ensures that the disinfection systems are operating effectively. Verification includes microbiological analysis of the process water linked to the operational monitoring outcomes of physico‐chemical parameters. Food business operators (FBOps) should set up and validate a tailored WMP to identify physico‐chemical parameters, as well as microbial indicators and their threshold levels, as performance standards for maintaining the fit‐for‐purpose microbiological quality of the process water during post‐harvest handling and processing operations.

Authors: Ngangom Purnima
Published: January 2025

The article presents adiverse aspects of print making in India particularly highlighting and making critical assessment on various works of Krishna Reddy. The paper attempts to decipher the experimental works that the artist had created during his lifetime. A brief historical account beginning from his first poster rebellion for quit India movement, his time at Shantiniketan and major influences on his life particularly in his work at Hatelier, shall be discussed by analysing his life and works. Secondly, select pieces of some of his famous artworks are discussed with the author’s critical perspective. Focusing on subject matter, medium and form of the pieces; Reddy’s brilliance and finesse is brought to light. The vibrance in his works, dynamics of colours existing in 2D frames as a form of living art and the stories that emerge to both an experienced observer or not is discussed at length. Revealing the inner connections of motherhood, happiness, trauma, and mundanity evoked by his prints is reflected upon with care and dedication. Discussions are also put forth on the thematic connection between his arts using the deductions arrived from the lens of subject matter, form and medium of encoding information. The decoded material are layed out within the context of feelings, visuals and narrative elements. In conclusion, his legacy and influence on artists and aestheticians, resonating endlessly with time is discussed. His exuberance expressed as arts exceeds far beyond many forms of artistic expression, where his creativity is an outgrowth of his meticulous combination of engineering paints and his precise balance of viscosity.

Authors: Fatatit Abubaker , Kalyon Ali
Published: January 2025

Electro discharge machining is an energy based method that can cause fast electrode wear and dimensional errors. This study aimed to identify the optimum process parameters for processing 1.2767 steel using copper-based electrodes. The Taguchi optimization approach was used, and 18 pieces of 1.2767 steel were prepared for the experiments. The electrodes used were CuCoNiBe and CuNi2SiCr, and the electrode surfaces were sanded and polished before processing. The results showed that the CuNi2SiCr electrode produced the lowest overcut value of 0.07 mm, while the CuCoNiBe electrode had the highest observed overcut value of 0.320 mm. The discharge level had the most significant impact on overcut, while the type of electrode had the least. The optimal parameters for the CuNi2SiCr electrode were 12 A discharge current, 50 µs pulse duration, and 800 µs pulse off time.

Authors: Civelek Cem , Sevinc Bedri
Published: January 2025

In this research paper, beginning with the Lagrangian and generalized velocity proportional (Rayleigh) dissipation function of a physical/engineering system, the Lagrange-dissipative model ( {L,D}-model briefly) of the system is initially developed. Upon satisfying the prerequisite condition for a Legendre transform, the Hamiltonian function can be obtained. With the Hamiltonian function and the generalized velocity proportional (Rayleigh) dissipation function, dissipative canonical equations can be derived. Using these dissipative canonical equations as the state-space equations of the system allows for the investigation of observability, controllability, and stability properties. In addition to the equilibrium (or critical or fixed) points of the system, stability properties can also be verified through a Lyapunov function as a residual energy function (REF). Since the proposed method is valid for both linear and nonlinear systems, it has been applied to the Van der Pol oscillator/equation.

Authors: Akay Sefer Ozge
Published: January 2025

Herein, Polyaniline (PANI)/polyethylene oxide (PEO) - luffa cylindrica bio-composite films of various mass fractions (%) have been prepared via casting solution of emeraldine base polyaniline and cellulose extracted from luffa. The biopolymer films were structurally and thermally characterized using X-ray diffraction (XRD), Fournier Transform-InfraRed (FT-IR) spectroscopy, and differential scanning calorimetry analysis (DSC). Moreover, the electrical properties of conductive biopolymer solutions were measured by using the conductivity meter. According to the obtained results, treated luffa increases the conductivity of biopolymers. XRD results reveal that luffa increases the crystallinity of bio-composite films in comparison to PANI/PEO films. FTIR analysis proved the presence of functional groups of PANI, PEO, and luffa in the film structure. Also, an increase in the weight of luffa in the bio-composite film brings about an increase in the peak intensities of the O-H group. It is determined that luffa enhances the thermal stability of composites via the results of DSC analysis.

Published: January 2025

In this study, the design and optimisation processes of the link to be used in the steel track undercarriage system of a tracked vehicle are summarised. In the first stage, a preliminary model was created by considering existing design examples and constraints. Two different Finite Element (FE) models were built using the maximum driving torque and track - ground contact forces. According to the results obtain from the analyses, three critical regions where stress concentration occurs, were identified. Seven structural design parameters were chosen to minimise stress concentrations in these regions. A Design of Experiments-based optimisation study was performed using these parameters. After obtaining new dimensional values, a new link design was created. The FE analyses conducted for maximum torque case showed that approximately decrease of 61%, 55%, and 20% was obtained in terms of stress concentration at the first, second, and third critical regions, respectively. Under the effect of vertical and lateral forces, the improvement percentages are 63%, 26%, and 31%, in the same order. It was observed that the stress values obtained at the critical regions of the new design under the failure loads, were below the permissible values.

Authors: Kaya Ertuğrul
Published: January 2025

Lubricants derived from plant-based raw materials offer great potential for the development of environmentally friendly and renewable esters due to their easier and faster biodegradability, reducing dependence on petrochemical raw materials and creating new synthesis processes. The increasing burden of environmental regulations and the depletion of petroleum-derived raw materials have prompted many industries to opt for products based on natural raw materials. Due to these positive effects, vegetable oil-based esters have recently been considered as potential candidates for industrial use. In this context, ester synthesis from cottonseed oil, a natural biodegradable raw material source, was carried out by transesterification with isopropyl alcohol. The structure of the synthesized ester was elucidated by GC-FID and FTIR and important physical parameters such as acid number, saponification
number, viscosity and density of the ester were investigated. The synthesized isopropyl cottonseed oil ester was used to formulate a synthetic metalworking fluid at concentrations of 2%, 4% and 6%. The tribological properties of the formulated metalworking fluid were evaluated using the Reichert test and the chip corrosion test. It was found that the addition of 6% isopropyl cottonseed oil ester to the synthetic metalworking fluid exhibited the best tribological properties.

Published: January 2025

Determining the health status of cancer patients is of vital importance in the cancer treatment process. This process plays a critical role in assessing patients' quality of life and supporting the treatment process. We thought that the use of machine learning in the field of cancer treatment and patient care could contribute to better patient outcomes and increased quality of life. Evaluation results of cancer patients who received home health care from XXXXXX and Research Hospital between January 2013 and August 2017 were discussed and 1000 patient files in home health service patient records were prospectively examined. In this article, cancer types were classified with machine learning methods using the Visual Analog Scale (VAS), Karnofsky performance scale, ECOG, Katz and Bartel scores to determine the quality of life of cancer patients receiving home health care. This study includes the evaluation results of 132 patients, 69 women (mean age 60.31±9.61) and 63 men (mean age 62.36±9.58). The DT classifier was noted to exhibit 83.3% accuracy and had the highest sensitivity in the lung cancer type, with a sensitivity of 88.9%. SVM classifier reached the highest accuracy compared to other classifiers with 90.2% accuracy. SVM has the highest sensitivity in lung cancers, with a sensitivity of 97.8%. The ANN classifier achieved 88.6% accuracy for all cancer types.The use of machine learning algorithms may provide a more sensitive and objective way to evaluate patients' response to treatment. The machine learning model allows determining the type of cancer using the feature space based on VAS, Karnofsky performance scale, ECOG, Katz and Bartel scores. This situation can also be constructed as an indicator in early diagnosis or risk group determination, and thus can contribute to improving home health services and increasing the quality of life of cancer patients. The results of this study may contribute to studies aimed at developing more effective strategies for the care and treatment of cancer patients.
Linearization of Photovoltaic Cell Single Diode Equivalent Circuit Model Using Piecewise Linear Parallel Branches Model and Findin Fill Factor
Authors: Adak Suleyman
Published: January 2025

In this article, the linearization and analysis of the Photovoltaic (PV) cell single diode equivalent circuit model have been performed. The diode element in the PV cell equivalent circuit model is a nonlinear component. The nonlinear PV cell single diode model has been linearized using the piecewise linear parallel branches model. In addition, the maximum power and fill factor (FF) of the PV cell have been determined based on the equivalent circuit parameters. Thevenin theorem was used in this analysis process. For this theorem to apply, the circuit must have a linear characteristic. The linearization of the nonlinear diode element has been achieved through the piecewise linear parallel branches model (PLPBM). In practice, the aim is to transfer the maximum power (Pmax) from the PV cell. Another important parameter of the PV solar cell is the FF. The FF is used to describe the general behavior of a solar PV cell. This factor is used to determine the quality of the solar PV cell. The FF provides information about the quality and efficiency of the solar cell. In a low FF scenario, the value of the series resistance is high, while the value of the parallel resistance is low. The FF of typical PV cells ranges between 50% and 82%. In the analysis conducted in the article, the FF of the PV solar cell was found to be 74%.

Lightweight concrete types have gained attention today due to their diverse range of applications. Cellular concretes such as aerated concrete and foam concrete hold a significant place in the construction sector due to their sustainability and recyclability. These materials stand out for their high efficiency, offering properties such as thermal insulation and fire resistance. In particular, pore size and distribution in foam concrete are among the most critical factors determining the mechanical strength and insulation performance of the material. In this context, understanding the chemical composition and properties of the foaming agent in detail is essential for achieving the desired performance. Surface-active agents, known as surfactants, are important components widely used in foam concrete production. The correct selection and application methods of surfactant types are crucial for ensuring that the concrete achieves its targeted properties. This study aims to examine the characteristics of various surfactants and contribute to meeting the desired performance criteria in foam concrete production.

Authors: Türk Yılmaz , Balaban Berkan
Published: January 2025

Remote sensing technologies have the potential to provide cost-effective, fast, and easy solutions for the
determination of surface changes (material volume) after quarrying (open-pit mine) activities. In areas where the topography is rugged and difficult to access, the use of ground measurement techniques causes difficulties. In such cases, the use of remote sensing techniques is indispensable. The Post Processing Kinematic (PPK) measurement technique provides an alternative solution to other photogrammetry methods in areas whose topography is not suitable for satellite-based positioning. This study investigates the applicability of the UAV based PPK method for the calculation of cut volume in quarry operations. The study area was selected as a quarry located within the boundaries of Tatlıdere Forestry Operation Chief in Düzce province and operated by a legal entity. Using a DJI Phantom 4 RTK unmanned aerial vehicle (UAV) with a PPK application module, a total of two flights in PPK flight mode were performed at the quarry on 30 September 2021 and 19 May 2022 (covering a period of approximately 7 months). The material volume, which is important for quarry operation, was calculated
and the excavation volume in the two flight time intervals was found to be 104.170 m³ and the cut area was found to be 44.348 m2. According to the results obtained, UAV systems should be used in quarry management in terms of time and work safety in obtaining data.

Published: January 2025

As a result of the rapid increase in the world population, the problem of balanced and adequate nutrition has emerged, and the importance of animal production has increased even more. In this respect, to ensure sufficient and balanced nutrition of existing animals, there is a need to increase the cultivation areas of fodder crops and proper management of pastures and breeding studies. For this reason, fodder pea (Pisum sativum L.), which has high nutritional value and is preferred for animal consumption, is a vital fodder plant to meet this need. Fodder peas are suitable for consumption as animal feed because they contain high levels of carbohydrates and digestible substances. However, salinity, one of the abiotic stress factors, is an essential problem for fodder peas. Salinity significantly limits the development of the plant and leads to yield losses. Although the consequences of climate change vary in many parts of the world, it is predicted that the frequency and severity of conditions such as decreased precipitation, increased temperatures, floods, droughts, and increased saline areas will increase with climate change in developing countries. In addition, salt stress also affects the photosynthetic mechanism in plants and causes changes in chlorophyll, carotenoid, phenolic, and antioxidant concentrations. Since the reclamation of saline farmland is expensive and complex, it is more appropriate to grow salinity-resistant plants. Therefore, gene studies to improve the salinity tolerance of plants have gained momentum in recent years. In this review, studies conducted in the last 20 years are discussed. Salt tolerance in gene-transferred and non-transferred peas, as well as plant growth in a saline environment, were assessed by comparing proline, chlorophyll, total phenolic, and antioxidant levels. In summary, this study seeks to highlight the issues of drought, aridity, and salinity, all of which are expected to worsen as climate change progresses.
