Published: March 2024

Purpose–The purpose of this study is to examine firm-level and macroeconomic determinants of R&D investments in Turkey. Design/Methodology/Approach–This study employs two groups of variables to explain R&D investments of publicly traded firms in Turkey. The first group contains firm-level financial indicators, containing liquidity, profitability, tangibility, productivity and financial leverage. The second group includes macroeconomic variables such as inflation rates, industrial production, economic growth, foreign trade and foreign direct investments. To exhibit the impact of two groups of factors, this study applies twopanel data regression models. Findings–The findings indicate that macroeconomic variables do not explain firm-level R&D investments. The only significant variable is inflation rates, which have an adverse effect on R&D decisions. On the other hand, firm-level financial variables explain the variation in R&D investments quite well. Liquidity and financial leverage significantly and positively influence innovation and research while profitability has a negative impact on them.Discussion–The results indicate that firm-level R&D expenditures are mostly robust to macroeconomic conditions, while internal determinants are more significant in explaining R&D behavior

Aim: The lung is the second most frequent site of metastatic dissemination. Early detection is key to improving survival. Given that the lung interfaces with the external environment, the collection of exhaled breath condensate (EBC) provides the opportunity to obtain biological material including exhaled miRNAs that originate from the lung.

Methods: In this proof-of-principal study, we used the highly metastatic MDA-MB-231 subline 3475 breast cancer cell line (LM-3475) to establish an orthotopic lung tumor-bearing mouse model and investigate non-invasive detection of lung tumors by analysis of exhaled miRNAs. We initially conducted miRNA NGS and qPCR validation analyses on condensates collected from unrestrained animals and identified significant miRNA expression differences between the condensates of lung tumor-bearing and control mice. To focus our purification of EBC and evaluate the origin of these differentially expressed miRNAs, we developed a system to collect EBC directly from the nose and mouth of our mice.

Results: Using nanoparticle distribution analyses, TEM, and ONi super-resolution nanoimaging, we determined that human tumor EVs could be increasingly detected in mouse EBC during the progression of secondary lung tumors. Using our customizable EV-CATCHER assay, we purified human tumor EVs from mouse EBC and demonstrated that the bulk of differentially expressed exhaled miRNAs originate from lung tumors, which could be detected by qPCR within 1 to 2 weeks after tail vein injection of the metastatic cells.

Conclusion: This study is the first of its kind and demonstrates that lung tumor EVs are exhaled in mice and provide non-invasive biomarkers for detection of lung tumors.
New approaches and prospects of immunotherapy and gene therapy for prostate cancer
Authors: Bibi Roshni , Sarkar Koustav
Published: March 2024

Prostate cancer stands as the most prevalent cancer globally, constituting 21% of all cancer diagnoses in male patients. Urgent optimization of prostate cancer care is essential, given that this disease claims 345,000 lives every year. These innovative approaches hold substantial promise for both researchers and patients, representing a beacon of hope in the inhibitory act against prostate cancer. Prostate cancer's gradual advancement deems it suitable for immune therapy, but trials in metastatic cases show limited effectiveness, likely due to compromised immunity. Hindered by defective cellular responses, an immune-suppressive microenvironment, emerging evidence and breakthroughs, such as CAR-T therapy, inspire cautious optimism for advanced prostate cancer immunotherapy. Tumors utilize tactics to escape immune recognition, promoting the proliferation of MDSCs, Treg cells, and TAMs. Immunotherapy targets prostate cancer by mostly expressed target proteins and overexpressed target proteins. Immune cells play a role in tumor development and metastasis in advanced prostate cancer. Modulating the tumor microenvironment presents therapeutic possibilities. Certain prostate cancer types exhibit potential responses to immune checkpoint inhibitors, yet obstacles remain, necessitating additional research for enhanced efficacy. Immunotherapy faces hurdles in prostate cancer—limited inflammation, scarce antigens, and a resistant microenvironment. Grasping resistance intricacies is pivotal. The identification of DNA's helical structure propelled global progress in disease treatment through gene therapy. Choosing gene therapy vectors is critical; viruses are potent but toxic, while nonviral options, though less toxic, encounter barriers affecting transfection. In the realm of prostate cancer treatment, immunotherapy and gene therapy are emerging as increasingly viable options.

Measuring the Impulse Buying Behaviour of Consumers: Special Reference to Food and Beverages
Authors: Nidhi Sheoran
Published: March 2024

Impulse buying is when buyers make unplanned purchases that sometimes leave them satisfied or dissatisfied. The present study surveyed 546 customers who purchased food and beverage brands to understand their buying behaviour in the state of Haryana, India. The study used a well-structured questionnaire, collected data via social media platforms, and drew inferences using frequency and descriptive analysis. The results reveal that most consumers tend to buy impulsively regarding food and beverage products. The findings further reveal that consumers make impulsive purchases based on specific choices, preferences, or attachments to brands without considering the brand’s features or other characteristics. Companies can use these inferences to understand the target market’s purchasing patterns and make informed decisions to boost sales. The study recommends that food and beverage companies adopt strategies to attract impulsive buyers based on demographic features and focus on packaging to attract consumers with different personality traits.
Internationalisation For All: Rethinking University Internationalisation
Authors: Rajkhowa Gautam
Published: March 2024

Concerns about commercialisation, high costs of study, elitism, massification, and the challenge of quantity over quality are some of the common themes across the globe in the discussions on international higher education.
Viewed through the lens of a small public university in the UK, this paper presents the results from a study examining the meaning of internationalisation, its practice, and what it means in the context of an inclusive international higher education strategy.
It argues that in a world where 97% of the world’s student population engaged in higher education is not globally mobile for a variety of reasons, internationalisation to be inclusive must adopt a holistic approach and be woven into the fabric of the institution’s life. Implemented as a Whole Institution Initiative (WII), this must be accompanied by clear Intent, Investment, and Infrastructure (3 I’s), connecting strategy, policy, and day-to-day practices at all levels and functions of the institution.
The framework that has been developed as a result of this study provides insight and practical guidance to Higher Education institutions on how to approach internationalisation holistically. At a strategic level, it will be useful to institutional leaders and national policymakers to understand the issues entailed in formulating international strategies, processes, and programmes in developing an inclusive internationalisation strategy and not merely focusing on international student recruitment and inward mobility. At a course/programme level, it provides valuable practical insight and guidance to academics and programme administrators involved in developing and delivering inclusive internationalisation.
Health Conditions of Inter-State Migrants in Marine Fisheries: A Study of Kerala
Authors: MU Jenikrishna , Jaysawal Neelmani
Published: March 2024

The marine fisheries are one of the vital occupations in the southern parts of India. This industry is considered to be the foundation of revenue generation for these states. Kerala, being located at the southernmost part of India, is promoting this industry with support from inter-state migrant labourers. The inter-state migrants working in Kerala’s maritime industry are from northern and southern India. As a result of higher salaries and improved working conditions in this unskilled sector, people from the North and Eastern parts of the country have started to migrate to Kerala. Indeed, the continual cash flow in this sector makes it lucrative and invites a large influx of migrant labour to this region. These inter-state migrant labourers work for more than eight hours and spend 10 to 15 days at sea while fishing. They have to stay with heavy pieces of equipment at sea away from shore. This heart-wrenching situation deteriorates their health. They come across various kinds of professional injuries while fishing. Some of these fishermen and fisherwomen encounter long-term effects from those injuries.
On the other hand, catering to their health needs seems challenging due to the lack of adequate medical facilities for migrant labourers. Following the increase in migratory flow, Kerala’s health system has faced several institutional impediments. The lack of identification of migrant labourers cripples the entire process of providing access to a better healthcare system to them. As a result, inter-state migrant labourers in the marine industry are facing various health-related challenges due to the nature of this profession and the apathy of state machinery.
Therefore, this study seeks to explore the health issues affecting the inter-state migrant labourers in Kerala’s marine sector through a mixed-method research design.

Authors: Karmakar Uttam , Sarma Amiya
Published: March 2024

This study examines the relatively unexplored domain of Information and Communication Technology (ICT) trade between India and the African Union (AU), applying the Stochastic Frontier Gravity Model (SFGM) to measure the untapped potential and discern factors that impede trade. It points out India’s burgeoning role in global ICT trade, with the AU being an increasingly valuable market due to its digital growth and young population. The research identifies India’s significant comparative advantage in exporting telecommunication equipment, with a Revealed Comparative Advantage of 3.54, strategically enhancing its position in the global marketplace. The research notes the high trade complementarity index of 0.984 in 2021, indicating a strong synergy between India’s export capabilities and the AU’s demand, suggesting a beneficial trade relationship. It acknowledges the shift in Africa’s ICT import partners, highlighting China’s rising influence and the need for India to solidify its market share in Africa strategically.
The SFGM’s application to evaluate trade efficiency, considering factors such as GDP, exchange rate, distance, tariff rate, and language, provides insightful conclusions. Positive impacts of GDP, exchange rate, and shared language on bilateral ICT trade are found to be significant. The findings emphasise the importance of strengthening trade ties for economic development and digital transformation in Africa.

Assessment of DNA/RNA Defend Pro: An Inactivating Sample Collection Buffer for Enhanced Stability, Extraction-Free PCR, and Rapid Antigen Testing of Nasopharyngeal Swab Samples
Authors: Claeys Mikhail
Published: March 2024

This study comprehensively evaluates the DNA/RNA Defend Pro (DRDP) sample collection buffer designed to inactivate and stabilize patient samples. The primary objectives encompassed assessing DRDP's efficacy in ensuring sample stability, facilitating extraction-free polymerase chain reaction (PCR), and ensuring compatibility with rapid antigen testing.Ninety-five diagnostic nasopharyngeal swab samples tested for influenza A/B, RSV A/B, and/or SARS-CoV-2 were diluted 1/10 with DRDP and anonymized. Stability testing involved incubating 31 positive samples at 4 °C, 20 °C, and 37 °C for 7 days, with regular extraction-free nucleic acid amplification testing (NAAT).Results demonstrated that DRDP guaranteed viral RNA stability at all temperatures for influenza, SARS-CoV-2 and RSV showing stability up to 7 days at 4 °C. DRDP-diluted samples exhibited robust compatibility with direct PCR, as 72 out of 88 samples positive for cobas Liat also tested positive for direct PCR. Non-concordant results could be explained by the 200-fold lower input in the extraction-free NAAT.Compared to NAAT, rapid antigen testing demonstrated lower sensitivity, as expected, while maintaining perfect specificity. Clear cutoffs between positive and negative rapid antigen testing results were observed in both cobas Liat and direct PCR analyses, validating DRDP's compatibility with these techniques. In conclusion, DRDP is an effective stabilizing medium compatible with direct PCR and rapid antigen testing and shows great potential for optimizing diagnostic processes, particularly in resource-limited or time-sensitive scenarios.

Authors: Xu Tengda , Wu Junliang , Yang Tengwei , Qin Jiajia
Published: March 2024

This paper concentrates on computing the efficiency of heliostat field systems. By conducting a comprehensive analysis of the mathematical model for optical efficiency, we have effectively simplified the complex three-dimensional illumination problem of heliostat fields into a two-dimensional issue. Our work primarily investigates the calculation methods for the average optical efficiency and output power of heliostat. Traditionally, calculating shadow and blocking efficiency, key factors affecting the optical performance of mirror fields, has posed a significant technical challenge. Through innovative improvements to the Monte Carlo simulation technique, this study has successfully reduced the spatial dimensionality of the problem. We employed a series of novel coordinate transformations to simulate light tracing on a two-dimensional plane, thereby efficiently calculating the efficiency of shadows and obstructions. Not only have we solved the computational challenges of shadow and obstruction efficiency, but our unique algorithm design also allows us to precisely obtain the overall average optical efficiency of the heliostat field while enhancing computational efficiency.

Modelling of Real Gas Compression Using the Finite Volume Thermofluid Network Methodology and Mean-Line Approach for Centrifugal Compressors
Authors: Laubscher Ryno , Rousseau Pieter , van der Spuy Johan , Sart Colin Du , Pretorius Johannes P.
Published: March 2024

A novel compressible real gas 1D finite volume thermofluid network modelling methodology is proposed that can be applied in the analysis of supercritical CO2 (sCO2) power cycles. It is applied to simulate centrifugal compressor performance via a mean line approach that directly solves the mass, energy, and momentum balance equations for the discretized flow channels within the machine along with the associated loss models, component characteristics, and applicable compressible real gas equation of state. This can be integrated seamlessly with the rest of the power cycle components like pipes, valves, heat exchangers, etc., thereby eliminating the need for static performance maps and the associated difficulties to ensure similarity over the whole range of operation. This direct simulation of the internal flows also makes it possible to do integrated cycle design optimization that includes the geometry of the compressors, and to simulate fast transients for dynamic analysis. The methodology was applied to simulate well-documented air and sCO2 centrifugal compressors and compared the generated results with that of conventional thermofluid network incompressible and compressible ideal gas approaches. The results indicate that the proposed compressible real gas approach can capture the stagnation pressure changes and isentropic efficiencies with good accuracy for both cases over the whole range of mass flow rates and shaft rotational speeds. In contrast, the conventional thermofluid network incompressible and compressible ideal gas approaches are only applicable in selected regions of the fluid property regime and suffer from discretization errors and inappropriate treatment of the relationship between stagnation and static pressures. Furthermore, comparative analyses between the newly proposed approach and the traditional mechanical energy balance method are performed, showing that the latter approach needs to be discretized more finely through the compression process to correctly capture the polytropic compression path shape, whereas the former more accurately captures the stagnation pressure changes through the analyzed compressors with only a single increment per compressor component.
Analysis of Behavioural Thermoregulatory Responses in Giraffa, Regarding Temperature and Sunlight Exposure during Daylight Hours
Authors: Masterman Rowan Samuel
Published: March 2024

Research topics surrounding the giraffe have been subject to recent disagreement, with work focusing on taxonomy over ecological phenomena such as behavioural thermoregulation. Much interest in taxonomy arises around the existence of distinct local populations of giraffes, often enclosed in small, fenced reserves, preventing natural gene flow. Targeted management of reserves may act as a buffer for declining populations, providing landscape that minimises requirements for thermoregulatory behaviours. Notable behaviours include shade-usage via trees and other giraffes, and positioning of the body towards the sun, employing an individual’s own neck as a shade source. Breeding programmes and translocation of individuals away from large communities on fenced reserves may increase giraffe population numbers across their range; however, the genetic diversity of large populations in enclosed spaces may be called into question. 55 of the 57 giraffes from the population on the Mogalakwena River Reserve (MRR) were observed over eight months, recording thermoregulatory behaviours such as body positioning in response to sun exposure, and shade usage; behaviours both noted in secondary works. These behaviours were compared across identities, such as sex and age, to assess how thermoregulation varies per individual. The population on the MRR spent more time facing the sun during high temperature days, with adults, sub-adults, males, and dark-coated individuals prioritising the behaviour beyond other individuals. Body positioning behaviours of individuals were also found to be more important in thermoregulation than shade-seeking, with shade usage decreasing on hotter days. Positional behaviour, disregarding identity, was also observed across wet and dry seasons, with a clear contrast; giraffes face the sun significantly more during the hotter wet season. The behaviours observed in this work provide an insight into the direction conservational strategies may take on closed reserves. However, further work is required on other reserves with varied population structures, to determine whether one strategy may be implemented across the giraffe's range, or whether specialised strategies are required in individual locations.
Technology of Controlled Film Flow Granulation of Materials
Authors: Kazachkov Ivan
Published: March 2024

The new unique technology for granulation of metals and nonmetallic melts is presented in the paper. It was created on the newly developed controlled film flow disintegration with rapid cooling of the droplets and solidified granules in amorphous state. Three new phenomena discovered by us created the base for 3 different methods for granulation of metals and nonmetallic melts in a wide range of granules’ sizes. Electromagnetic resonance method allows producing granules of metals in the range of 1 mm and over. The soliton-like vibrational regime is available for production of any granulation material in the range 0.1-1 mm. Moreover, the shockwave regime is applicable for producing particles from 10 micrometers by size. All methods produce particles of the stated size with a narrow distribution by size: deviation from the average size no more than 50%. The other known methods do not produce granules with such high cooling rate, which can realize the amorphous state and cannot regulate size of particles in such bright but narrow range from 10 micrometers to 1-2 mm.
Pulsed Propulsion of Unmanned Aerial Vehicles by Centrifugal Force Modulation - First-Order Theory and Practicability
Authors: Holzapfel Dr. Wolfgang
Published: March 2024

A novel technique suitable for propulsion of small unmanned aerial vehicles (UAV) is discussed in this paper. This approach utilizes the rotational energy of airborne gyro rotors and converts it into translational propulsion for the vehicle. The energy conversion is achieved by generating precisely directed centrifugal force pulses through short-duration rotor unbalances. The accurate control of the timing and magnitude of these unbalances is crucial for successful propulsion generation. Our first-order theory of controlled unbalance propulsion (CUP) predicts the potential for achieving high translational accelerations and vehicle velocities up to orbital levels. Power saving levitation of UAVs can be attained. In this paper, we provide traceable evidence that pulsed centrifugal propulsion is based on well-established laws of physics and can be realized using state-of-the-art technologies.
CX3CL1 (Fractalkine)-CX3CR1 Axis in Inflammation-Induced Angiogenesis and Tumorigenesis
Authors: Szukiewicz Dariusz
Published: March 2024

The chemotactic cytokine fractalkine (FKN, chemokine CX3CL1) has unique properties resulting from the combination of chemoattractants and adhesion molecules. The soluble form (sFKN) has chemotactic properties and potently attracts T cells and monocytes. The membrane-bound form (mFKN) facilitates diapedesis and is responsible for cell-to-cell adhesion, especially by promoting the strong adhesion of leukocytes (monocytes) to activated endothelial cells with the subsequent formation of an extracellular matrix and angiogenesis. FKN signaling occurs via CX3CR1, which is the only known member of the CX3C chemokine receptor subfamily. Signaling within the FKN-CX3CR1 axis plays an important role in many processes related to inflammation and the immune response, which often occur simultaneously and overlap. FKN is strongly upregulated by hypoxia and/or inflammation-induced inflammatory cytokine secretion, and it may act locally as a key angiogenic factor in the highly hypoxic tumor microenvironment. The importance of the FKN/CX3CR1 signaling pathway in tumorigenesis and cancer metastasis results from its influence on cell adhesion, apoptosis and cell migration. This review presents the role of the FKN signaling pathway in the context of angiogenesis in inflammation and cancer. The mechanisms determining the pro- or anti-tumor effects are presented, which are the cause of the seemingly contradictory results that create confusion regarding the therapeutic goals.

Each region has the potential to grow and develop according to their respective conditions. The difference in these conditions results in inequality in the speed of growth and development in each region, this condition is known as disparity. The gap will be a problem if there is a gap that is too large and is caused by the wrong development system, so that it can be a cause of unrest, dissatisfaction and even a separatist movement that wants to separate itself from the Unitary State of the Republic of Indonesia. The basic problem in regional development in the Metropolitan Area, especially Malang Raya is the gap between regions where development is monocentric, centered on Malang City. Responding to such conditions, it is necessary to formulate a regional disparity system in Malang Raya, to find out the extent to which development and regional growth are concentrated in Malang Raya. In addition, it is hoped that through the formulation of the regional disparity system, it can be a reference so that the direction can minimize regional disparities in Malang Raya.

Penelitian ini bertujuan mengkaji tentang Pertunjukan Wayang Timplong dalam Tradisi Bersih Desa di Desa Putukrejo, Nganjuk Jawa Timur Tahun. Wayang Timplong merupakan kesenian tradisional khas Nganjuk, Jawa Timur. Wayang Timplong memiliki keunikan diantaranya; terbuat dari kayu yang ditatah hingga pipih dengan pahatan membentuk wajah dan ornamen lainnya yang diberi warna. Pertunjukan Wayang Timplong tidak memerlukan bayangan dikarenakan bentuk wayang sudah tergambar jelas sehingga pertunjukan wayang  dapat digelar pada pagi, siang, sore atau malam hari. Wayang Timplong pada masa kejayaannya biasa digunakan masyarakat dalam berbagai acara diantaranya; pernikahan, khitanan, syukuran, tradisi bersih desa, ruwatan dan nandar. Seiring perkembangan jaman Wayang Timplong mulai ditinggalkan masyarakat dan hingga saat ini hanya acara-acara tertentu yang masih bertahan menggunakan Wayang Timplong seperti; tradisi bersih desa, ruwatan dan nandar karena berkaitan dengan kepercayaan masyarakat yang diturunkan oleh nenek moyang melalui sebuah tradisi bahwa Wayang Timplong mampu menghalau segala macam bencana pada suatu desa. Wayang Timplong mengandung nilai-nilai kehidupan dan pendidikan karakter yang digambarkan melalui cerita yang bertemakan Panji.

The growing sensitivity of consumers about animal welfare and the awareness of its impact on food security and safety recently influenced international policies and law scenario. To response to these needs, in 2018, the Italian Ministry of Health commissioned the development of a system named ClassyFarm able to categorizes the level of risk arising from farm animal welfare. The experts involved in the project provided specific checklists to analyze different animal species and housing system. The developed welfare measurement protocols consist of both resource-based and animal-based measures and are divided into three areas: (Area A) “Farm management and staff training”, Area B) “Housing and equipment”, (Area C) “Animal-based measures”. The aim of this study was to measure welfare conditions in cattle herds reared in the Aosta Valley through the ClassyFarm checklist for tie-stall dairy cattle. The scores (%) for each area of assessment were divided into three classes (insufficient, acceptable, and optimal) while the total Animal Welfare Score (AWS), obtained by summing the scores of the 3 areas, was divided into five classes. The total AWS showed the majority of the farm included in good to optimal result.

Sulfonamides represent a wide class of synthetic drugs commonly used in veterinary therapy for the treatment of several bacterial and protozoan infections in cattle, swine and poultry. The use of these drugs in farming can lead to the possibility of having their residues in animal products intended for human consumption. Consequently, to ensure high consumer protection, for sulfonamides European Union (EU) set a Maximum Residue Limit (MRL) equal to 100 µg/kg, either as a single molecule or as a sum of all detected compounds within the class). Official laboratories are directly involved in the execution or residue plans by developing, validating and then applying analytical methods for the measurement of drug residues. Accordingly, official laboratories should update their procedures following the evolution of required drugs and MRLs. A multiclass method previously developed and validated for the determination in animal muscle of ten classes of antibiotics was adjusted to comply with the current European requirements which establish the minimum set of sulfonamides to be determined. Therefore, eight new sulfonamides were added assessing method performance characteristics according to European Regulation (EU) 808/2021.

Monitoring daily cow behavioural activities of cows in livestock farms is strategic for improving the herd management. For this reason, IoT techniques and smart sensors are become the most common technological support in barns.
The aim of this paper is to validate the use of predefined accelerometer thresholds in timely detecting of cow behavioural activities through the statistical analysis of the data acquired from accelerometers housed in collars. Applying ANOVA and TUKEY tests to the median of the accelerations measured with 4 Hz sampling, the behavioural activities analysed in this study, i.e., feeding, lying, rumination, were found to be discriminable along one or more axes. This could allow the implementation of threshold-based algorithms in the firmware of devices housed in the cow collars.

Clove oil is an essential oil that has recently been used not only as a health or aromatherapy ingredient but is also widely used as an additive in fuel, especially for compression ignition engines. Essential oils are extracted through distillation from various parts of the clove tree, such as flowers, tree bark, leaves, and even fruit. This study aims to evaluate the combustion performance of a spark-ignition engine fueled by gasoline and essential oil at a concentration of 5-20 % as a blend. This type of research has not been conducted by many researchers, making it difficult to find scientific references related to this type of research. Experiments carried out on a research engine with engine speed variations of 1400–1800 rpm and a constant load of 3 kg. The results show that increasing the essential oil content increases the fuel energy and indicative power, thereby increasing the thermal efficiency. However, the brake power will decrease because most of it is lost owing to heat transfer and friction; therefore, the mechanical efficiency decreases if the percentage of essential oil in gasoline increases. Meanwhile, increased essential oils will reduce CO2 emissions, but HC and CO emissions will increase, especially at high engine speeds.
