Navigating Geographical Indication Regime in India: It's effect on Market, Challenges and Suggestions
Authors: Kesari Khushi , Singh Shivani
Published: July 2024

Geographical Indication (GI) systems serve as crucial mechanisms within intellectual property, distinguishing products based on their unique qualities tied to specific geographic regions. Despite India's progress in registering 560 GI statuses, challenges persist, necessitating insights from global GI systems to refine and expand its framework. While the issuance of GI statuses has increased, attention must be directed towards maintaining and enhancing product quality post-recognition. Stringent quality control measures, adherence to standards, and continuous improvement are imperative to uphold authenticity and reputation in domestic and international markets. This research essay aims to provide a comprehensive overview of the Geographical Indication (GI) market while assessing the prevalent challenges. It underscores the significance of prioritizing quality assurance over quantity to enhance the value of Indian GI products. By analyzing various aspects of global GI systems, such as administrative efficiency, legal clarity, enforcement mechanisms, and international cooperation, this essay endeavors to identify effective strategies for strengthening India's GI regime and mitigating existing challenges.
Explaining the nature of the mass m of submicroparticles, and the phenomenon of mass variation with velocity V in ether
Authors: Has Ioan , Miclaus Simona , Has Aurelian
Published: July 2024

A brief history of mass nature is presented, including formulas for mass variation with velocity V.A new mass hypothesis (MH), on the nature of mass m is presented. Accordingly, the mass m0 of submicroparticle (SMP), is given by the kinetic energy accumulated inside the SMP, by the vortices/vibrations of groups of ether (ETH) cells, constituting the subsubmicroparticles (SSMP).These SSMPs will also create the inertial force (FI) of the SMP, due to the opposition manifested by ETH, toward any accelerated movement of SMP.A new explanation of mass m increase, with V is proposed, admitting the existence of ether in the form of our model, HM16.The entrainment of the surrounding ETH of SMP, takes place, with speed VETH, which stores the EETH energy. The spatial variation of VETH around the SMP, was analysed using the method of potential motions, for a cylinder, moving in water-like fluid, or in ETH, resulting a spectrum of the lines of current ψ, indicating the size of VETH, rapidly decreasing with distance r.So resulted the kinetic energy EETH stored by the movement of the outer ETH, which provides the supplementary mass ms. The case of SMP which acquires velocity V, approaching c, was analysed. Then, a phase change (PC) will take place, through which the SMP, transforms into photons (PHs), when movements of the ETH from the outside including energy EETH is transferred into PH photons, having velocity c, representing ETH’s property.
Attention Vulnerability Online: A Novel Framework to Understand Consumer Vulnerability in Online Environments
Authors: Puntiroli Michael , Perkovic Sonja , Bezençon Valéry , Kocher Bruno
Published: July 2024

Online environments provide unmatched convenience for consumers. However, they simultaneously expose consumers to tailor-made environments capable of capturing and steering their attention, which can lead them towards making suboptimal decisions. By integrating findings from vision science and marketing, we propose the novel concept of 'Attention Vulnerability Online' (AVO), representing a state in which consumers have reduced control over their attentional resources, putting them at risk of making suboptimal decisions. We argue that technological advancements, such as generative AI and machine learning, enable businesses to display visual attention drivers that, when combined with detailed knowledge about individual consumers, can direct consumers’ attentional resources toward specific online stimuli, thus rendering consumers vulnerable. We also examine the impact of key moderating factors that can exacerbate AVO - consumer-specific and situational characteristics that shape our attention. Our contributions are threefold: we provide a novel conceptual framework on AVO that connects vision science with consumer vulnerability, explaining when consumers are at risk of making suboptimal decisions in online environments; we identify areas warranting further investigation related to AVO; and we offer policy recommendations to ensure ethical online marketing practices.
Healing synchrony? Potential Benefits of Interpersonal Synchrony for Chronic Pain Management. Perspective
Authors: Swidrak Justyna
Published: July 2024

Fibromyalgia is called a pathology of misconnection at the neurophysiological, psychological, and social levels, and is characterized by widespread musculoskeletal pain, which is accompanied by a series of symptoms, such as chronic fatigue, depression, anxiety, body perception disturbances, and cognitive deficits. In this article, I argue that interventions that in various ways enhance interpersonal neural synchronization (INS) may bring long-term benefits to people with fibromyalgia (PwF). In the first part, I briefly introduce studies on INS in the general population. In the second part, I hypothesize that interpersonal synchrony can be healing for PwF, in the sense that repeated experience of being in sync with others may play a role in restoring both the brain-body and self-others connection in this population and consequently result in simultaneous lasting improvement of wellbeing. In the final part, I discuss potential future research directions.
Do people use counterexamples or subjective probabilities in uncertain conditional reasoning? Investigating human reasoning with an open response format
Authors: Gazzo Castaneda Lupita Estefania , Knauff Markus
Published: July 2024

Probabilistic approaches to human reasoning argue that all reasoning processes are inherently probabilistic and based on degrees of belief. To show this, participants are typically presented with scaled response formats, in which they can indicate how strongly they belief in a conclusion. However, the cognitive mechanisms behind uncertain reasoning remain unclear. How do people assess degrees of belief? This paper addresses this question by employing an open response format, allowing participants to decide on their own how to solve a reasoning problem. Thus, they could formulate their own conclusions and respond as spontaneously as possible without any constraints. Our findings reveal that participants generate more certain conclusions than is suggested by probabilistic theories of reasoning. Furthermore, counterexamples played a significant role, but in a more complex manner than previously assumed in the literature. Participants also gave uncertain conclusions based on probabilities, yet only for a subclass of inferences. We conclude that an open response format can provide valuable insights into how people naturally reason when not constrained by a particular research methodology.

Narcolepsy type 1 is a neurological disorder that severely affects sleep control due to a decrease in orexin neurons. Although research on neurological diseases, including narcolepsy, is vital for advancing science and improving human life, progress is hindered by the challenge of obtaining human brain samples as well as the difficulty in culturing neuronal cell lines. To overcome this obstacle, we generated Orexin-A neurons from human induced pluripotent stem cells (hiPSCs) by utilising a differentiation medium supplemented with N-acetyl-D-mannosamine (ManNAc) and Bone morphogenetic protein 4 (BMP4). The cells obtained from our study were characterised using immunofluorescence staining, real-time PCR, and competitive ELISA technique. The results show that our research successfully generated a hiPSC line with pluripotent stem cell characteristics. Furthermore, Orexin-A neurons derived from hiPSCs showed positive results for NCAM1 and TUBB3 markers, an increase in HCRT gene expression, and the capacity to secrete Orexin-A. These promising findings suggest that our hiPSC-derived Orexin-A neurons could serve as a foundation for cell-based disease modelling and further investigations into the underlying mechanisms of related neurological disorders.

This study aimed to investigate the blood glucose stabilising effect of extracts from Commelina diffusa Burm.f. on glucose tolerance test and diabetes test in white mice by streptozotocin. The diabetic mice were induced to hyperglycemia by intraperitoneal injection of streptozotocin in a single dose (170 mg/kg). Water extract, 96% ethanol extract, and 50% ethanol extract of C. diffusa were given orally for 7 days and the reference drug glibenclamide was given orally once on the 7th experimental day. The hypoglycemic effect was evaluated by quantifying fasting plasma glucose concentration and glucose tolerance test. The results of 96% ethanol extract of C. diffusa at two oral doses of 0.21 and 0.42 g/kg showed a more typical hypoglycemic effect than the water extract (0.36 and 0.72 g/kg) and 50% ethanol extract (0.49 and 0.98 g/kg) in both fasting blood glucose and glucose tolerance tests. The hypoglycemic effect of 96% ethanol extract of C. diffusa was equivalent to glibenclamide at a dose of 5 mg/kg measured in fasting state and was weaker than glibenclamide in the glucose tolerance test.

AN ANALYSIS OF THE IMPACT OF NON-PERFORMING ASSETS ON THE PROFITABILITY OF SRI LANKAN COMMERCIAL BANKS
Authors: Kalinga M.L.
Published: July 2024

Licensed commercial banks are considered entities that participate in financial intermediation, which bears risks in carrying out their activities. This study focused on analyzing how non-performing loans and advances, collectively non-performing assets, impact the profitability of commercial banks. The study focused on the Sri Lankan context of the phenomenon, where the commercial banking sector has received less attention than in other countries. The Central Bank of Sri Lanka's economic data library is the primary source of secondary data for this study. The target population of the study consisted of licensed financial institutions in the Sri Lankan banking sector, from which 24 licensed commercial banks were readily selected. Time-series data from 2001 to 2020 on the variables were collected to guarantee that reforms in the banking sector continued throughout the time. E-Views version 10 was used to conduct the statistical analysis of the data. The regression analysis results show that non-performing assets have a significant impact on the net profit of commercial banks in Sri Lanka and that the relationship between the variables under consideration is negative, leading to the conclusion that non-performing assets harm the net profit of commercial banks in Sri Lanka. The researcher encourages future studies to focus on a diverse sample to acquire a thorough perspective of Sri Lanka's banking sector. The study provides valuable insights to Sri Lankan commercial banks in managing credit risk associated with their operations.

Published: July 2024

The ability to effectively manage and assess knowledge has become indispensable for business survival, making knowledge management capability a crucial asset in the banking industry. This close tie between knowledge management and organizational culture presents an opportunity to boost bank performance through socialization practices. Recognizing the importance of culture in implementing knowledge management through socialization, this study explores its impact within the Sri Lankan banking sector, specifically focusing on all four domestic systematically important banks. Utilizing an inductive approach within an interpretive framework, the research investigates cultural dimensions that contribute to knowledge diffusion. While acknowledging potential sample bias due to respondent selection methods and head office limitations, 20 executive-level staff, from November 2022 to February 2023, participated. A priori thematic analysis, guided by the SECI model's socialization aspects, revealed leadership, team dynamics, communication, and mentoring as key cultural dimensions influencing knowledge diffusion. The study concludes that the chosen banks' cultures encourage prioritizing socialization-based knowledge management practices for improved performance.

The purpose of this research is a comparative analysis of the chlorophyll content in two varieties of winter wheat in different periods of plant development using an autonomous field device (N-tester) for operational measurement of nitrogen content and calculation of the optimal dose of nutrient application on winter wheat crops during different phases of vegetation. Methods and materials. The research was conducted in the Oleksandrivskyi and Bobrynetskyi districts of Kirovohrad region on the fields of two farms on winter wheat crops (varieties «Memory» and «Avenue») with selected control plots with an area of 3 m2 each. At the key moments of plant development, before applying fertilizers, chlorophyll was measured using the N-tester «CSM-200 Plus GPS» and the sugar content was measured with a refractometer «HT116ATC», after which the required dose of application of drugs was calculated. In both farms, fertilizing was carried out at the optimal time of fertilizer application, but the rates of fertilizer were radically different. Results. Wheat of the «Memory» variety in the control plot (the total amount of applied nitrogen was 198 kg/ha), starting from the earing phase, looked greener, taller, the ear had a larger size, the indicators of the N-tester and the content of sugars in the control plot had higher indicators, but also the ripening period in the control plot lasted longer than in the rest of the field (the total amount of applied nitrogen per year was 101 kg/ha). Winter wheat of the «Avenue» variety in terms of the main indicators in the control plot (the total amount of applied nitrogen 145 kg/ha) and in the field (the total amount of applied nitrogen 183 kg/ha) almost did not differ: the length of the ear, the height of the plant, and the color are the same, the indicators of the N-tester and the content of sugars are also almost the same. Therefore, it can be concluded that the introduction of an additional amount of 38 kg/ha per year was ineffective and did not increase productivity. Conclusions. Operational measurement of the nitrogen content in field conditions using the N-tester made it possible to effectively calculate the doses of nutrients applied to winter wheat crops during different phases of vegetation and contributed to increasing the yield level of the investigated crop varieties. Keywords: fertilizers, plant nutrition, winter wheat, refractometer, harvest, phases of plant development, chlorophyll, N-tester.

The functioning of innovative enterprises, their essence and content
Authors: Verenikina Aleksandra Olegovna
Published: July 2024

Modern trends in the development of the world economy «force» the enterprises of the Russian Federation to look for new ways to activate their production capacities. The core of this revitalization is innovation activity. Innovations permeate all types of society's activities and are the main factor and incentive for the development and competitiveness of the country.
The Russian economy has a high innovation potential, but the level of application of this potential and mastering of innovation processes is still not high enough. Innovation management is perceived by many specialists with distrust, which makes it difficult to choose a development path for the growth of innovation activity. In enterprises focused on the creation and implementation of innovations, this problem is very relevant.
The study of the essence of innovative enterprises, the peculiarities of their functioning will improve the quality of their management, and, consequently, will increase the level of economic development.

Hemostasis is an event that can be evaluated, and the incision of certain structures during surgical procedures can alter and consume coagulation factors. Therefore, this work aimed to evaluate the hemostatic parameters of dogs submitted to elective castration. For this, venous blood was collected in tubes containing sodium citrate from 16 (70%) female dogs submitted to ovary salpingohysterectomy and 7 (30%) male dogs submitted to orchiectomy, for evaluation of Prothrombin Time (PT) and Activated Partial Thromboplastin Time (aPTT) in the preoperative period. It can be observed that, in relation to PT (4.73 to 8.73s) and aPTT (10.18 to 23.88s), females presented minimum and maximum values similar to those in the literature. In turn, males presented PT at 4.21s to 6.16s and aPTT at 11.02 to 19.31s, data that corroborate with values observed in the literature. It can be concluded that the reported values of the evaluated hemostatic parameters were similar to those observed in the national and international literature.

A linear structure which is interpreted to be a fault was identified within the Precambrian basement complex rocks of the Ogbomoso Southwest Sheet 222 geological map, southwest Nigeria. The ground magnetic and electrical resistivity methods were used to investigate the structure and determine its physical characteristics. Five (5) traverses with lengths varying from 700–800 m and trending approximately NW–SE were established perpendicularly to the suspected fault. Total magnetic field data were acquired at 10 m interval, corrected for diurnal variation and inverted into 2D magnetic models using the Geosoft Oasis montaj software package. Dipole-Dipole resistivity data were acquired along the traverses using a dipole length of 20 m with expansion factor n varying from 1 to 5 and modelled to generate 2D resistivity structures with the DIPPROTM software package. Thirty-seven (37) depth sounding datasets were acquired, quantitatively interpreted and the results used to generate geoelectric sections across the suspected geologic feature. Three major magnetic dyke lineaments D1, D2 and D3 (60 – 164 m wide and 70 – ∞ depth extent) characterised by peak negative (−44 to −81 nT) magnetic anomalies and equivalent resistivity lineaments R1, R2 and R3 (50 – 140 m wide and 40 to >60 m depth extent) typified by low resistivity (10 – 750 Ωm) vertical discontinuities were delineated. The northern edges of lineaments D2 and R2 coincide significantly with the spatial location of the suspected fault F1 – F1 while D1 and R1 and D3 and R3 correlated and are newly identified parallel faults F2 – F2 and F3 – F3 to F1 – F1 and probably syngenetic with it.

Kendaraan merupakan suatu alat transportasi yang sangat dibutuhkan diberbagai sektor. Saat ini di bidang transportasi sering terjadi kasus pencurian terutama di kendaraan darat. Kasus curanmor pada ditahun 2017 di wilayah Jawa Tengah cukup tinggi mencapai 869 kasus. Kejadian ini menjadi keprihatinan diberbagai pihak, terutama pemilik kendaraan. Hal ini terjadi disebabkan beberapa faktor. Salah satu faktor yang dominan diantaranya lemahnya sistem keamanan kendaraan. Untuk menanggulangi kasus pencurian sudah banyak tindakan yang dilakukan. Penggunaan kunci kontak rahasia, alarm maupun teknologi kunci kontak dengan Immobilizer telah dikembangkan.  Faktanya kasus pencurian kendaraan masih marak terjadi. Hal ini menunjukkan sistem keamanan kendaraan masih rendah. Untuk itu perlu dikembangkan teknologi keamanan kendaraan yang lebih handal. Metode yang ditempuh dalam menangani permasalahan di atas, dengan mengembangkan teknologi recognition driver sytem. Teknologi fingerprint dan kamera pengintai juga dilengkapi dengan modul GSM untuk melakukan pengiriman SMS yang diaplikasikan dalam kegiatan ini. Fingerprint  memiliki kelebihan sulit ditiru oleh pihak lain dan data foto untuk mempermudah pelacakan tindak kriminal, serta SMS untuk memberitahukan bahwa kendaraan sedang tidak aman (indikasi pencurian). Dengan harapan security system yang dikembangkan akan lebih aman

Large amplitude dynamics of beam subjected to a compressive axial force resting on non -linear elastic foundation
Authors: Talib H. Elaikh
Published: July 2024

In this paper, the large amplitude of free vibration and buckling of Euler–Bernoulli beam rests on a non-linear elastic foundation subjected to an axial force are studied. Hamilton’s principle is followed to derive governing equation of the beam response. Using an analytical method based on the Galerkin technique,the nonlinear governing equations of motion was simplified to a time-dependent Duffing equation with cubic nonlinearities and then solved using Laplace Iteration Method. Comparison between results of the present work and those available in literature review shows reasonable agreement of this method. Effects of vibration amplitude, elastic coefficients of foundation and axial force on the non-linear natural frequencies and buckling load of beams are presented. Results reveal that decreasing linear and shear parameters and increasing nonlinear parameters of foundation lead to increasing frequency ratio and buckling load ratio. Furthermore, increasing axial force decreases absolute values of both linear and nonlinear frequencies as well as natural frequency ratio.
Analysis of Cyclostationary CR Detector for OFDM signals
Authors: Hussian K. Chaiel
Published: July 2024

The cyclostationary based spectrum sensing algorithm is especially suitable for detection of orthogonal frequency division multiplexing (OFDM) signals that exhibit strong periodic correlation due to insertion of cyclic prefix between OFDM blocks.Normally, the cyclic prefix is used to remove the Intersymbol interference (ISI) and intercarrier interference (ICI) of the OFDM signal and so it eliminates a need for complex equalizer. In this paper, simulation results demonstrate the normalized spectrum correlation function of the primary OFDM signal used in cognitive radio systems with different values of cyclic frequency. Two techniques are assumed to be used as PAPR reduction of OFDM transmitted signal. The results show that only one of them has no apparent effect on the correlation performance of the cyclostationary detector. Finally, it is found that a reduction of 30% in the implementation complexity can be taken by suitable choice of detector cyclic frequency.

The film cooling effectiveness and local heat transfer coefficient for coolant jet holes direction (orientation angle), have been investigated. Experimental investigations were done on a flat plate by using a single test transient IR thermograph technique.Evaluation of the cooling performance is obtained by estimated both film cooling effectiveness and heat flux ratios. Threemodelsof coolant jet holes are investigated,each model consists of two rows of holes arranged in a staggered way with different orientation angles. Model (1) downstream row with acute angle and the upstream row with obtuse angle; model (2) both rows with obtuse angles, while model (3) both rows with acute angles.The holes diameter is 4mm, the longitudinal distance between the upstream and downstream rows (X/D) is 4D, and the span distance between two neighboring holes (S/D) is 3D. Three blowing ratios of (BR= 0.5, 1.0, and 1.5) were used in the investigation program.In order to predict the flow behavior numerically for the cases under investigation CFDcode is introduced.The numerical investigation shows two large vortices large counter rotating vortex pair and horseshoe vortices ,both vortices have major effects on cooling performance.The experimental results showed that the film cooling effectiveness increases as blowing ratio increases for models (1 and 2), while decreases for model(3), and model (1) provide better performance than the others at high blowing ratios.

Published: July 2024

The laminar flow through an obstacled sudden expansion channel is numerically investigated.Rectangular adiabatic inclined obstacles mounted behind the expansion region on the upper and lower wall of the channel were used. The effects of obstacles inclination angle, obstacles length, obstacles thickness and the number of obstacles on the flow and thermal fields for different Reynolds number and expansion ratio were examined. The angle of obstacles inclination was taken in the direction of stream wise flow and ranged from 30° to 90°. Three values of expansion ratio(ER=H/h) equal to 1.5, 1.75 and 2 were used. The choice of values of Reynolds number takes the consideration of symmetry state. The body fitted coordinates system is used to transfer the considered physical problem to computational domain in order to treat the complexity arising from applicable the boundary conditions near the inclined obstacles. The governing stream-vorticity equations expressed in generalized coordinates system were transformed to algebraic equations by using finite difference method. The solution of these equations was done by iteration method. The obtained results showed that there is a significant effect of obstacles angle on the hydrodynamic characteristics. The performed tests of the present results with related published results showed that there is an acceptable agreement.

Published: July 2024

The aim goal of this research was to study the effect of using the waste-iron which product from milling processes on the mechanical properties of concrete. The tests performed to evaluate waste-iron concrete are compressive strength, splitting tensile strength and flexural strength tests. Sixty cubes of concrete for the compressive strength, sixty cylinders of concrete for the tensile strength, and Sixty prisms of concrete for the flexural strength tests with different volume fractions of waste-iron (1%, 2%, 3% and 4%) were prepared. The specimens were tested at 7, 14 and 28 days age. The results show that the concrete mixes with waste-iron have a higher compressive strength, tensile strength and flexural strength than the plain concrete mixes. Concrete containing volume fractions 3% ratio of waste-iron has the maximum value of compressive strength, tensile strength and flexural strength. The primary effect for adding the waste-iron to the concrete is to improve the post-cracking behavior.
