How quality conventions shape the governance of the dairy value chains of Senegal
Authors: Ferrari Serena , Duteurtre Guillaume , Corniaux Christian
Published: July 2024

Background: Over the past few decades, the Senegalese dairy sector has undergone a rapid transformation. Urbanization and shifts in urban consumers’ eating habits have contributed to increased demand for dairy products and the emergence of new quality requirements. Aim: This paper examines how quality conventions influence the governance of dairy value chains in Senegal. We argue that value chain governance is not only determined by transaction characteristics, but also by how “lead firms” incorporate different quality conventions and translate these into value chain governance mechanisms. Methods: Through semi-structured interviews with consumer groups and stakeholders in the dairy value chain (producers, importers, processors, and retailers), we collected information on consumers’ selection criteria for dairy products and processors’ quality strategies, as well as on coordination mechanisms, contracts, and power relations within the value chain. Results: Our results show that the way lead firms normalize consumer expectations leads to specific organizational mechanisms in buyer-supplier relationships. Some combinations of quality strategies and governance mechanisms are better suited to fostering the sustainability of the local milk value chain in terms of social and economic development. Processors building viable relations with local milk producers are in particular ensuring the sustainability of the value chain, since they are able to cater to consumer preferences for fair and local milk-based products, while offering the guarantee of food safety processes. Conclusions: Our study highlights the indirect power that downstream actors (consumers) have on upstream actors (producers) via strategies (normalization) implemented by actors operating in an intermediate segment of the chain (processors). In other words, it shows that consumers, through their purchasing preferences, are playing a key role in the development of the local livestock sector.

Análisis de errores en el uso del género gramatical en los alumnos persas de español como lengua extranjera
Authors: Parvizi Pardis
Published: July 2024

El español es una lengua con características únicas, como el uso del morfema de género gramatical y el artículo como determinante, lo que dificulta su aprendizaje para hablantes de lenguas como el persa, donde su lengua materna carece de estos elementos. La dificultad se profundiza aún más cuando se trata de la concordancia de género y número en los grupos nominales en español. En este estudio, se busca analizar un corpus de estudiantes persas de español utilizando la metodología de Análisis de Errores, con el propósito de identificar los errores frecuentes en cuanto al género gramatical en español, analizar las causas subyacentes y sugerir posibles soluciones para mejorar la comprensión y el uso del género gramatical en español entre los estudiantes persas.
Deontic modality in tourism scientific writing
Authors: Domínguez Morales Elena , Soto Déniz Isabel
Published: July 2024

Este artículo se centra en los verbos modales deónticos que aparecen en un corpus de artículos de investigación sobre turismo. La originalidad de este estudio radica principalmente en la selección de dos secciones fundamentales del artículo de investigación para su recepción e impacto como contribución científica, a saber, la introducción y la conclusión. Como ya se expresó en Álvarez-Gil y Domínguez-Morales (2018; 2021) y Álvarez-Gil (en prensa), el artículo de investigación en turismo es, con mucho, uno de los menos explorados. La metodología implica el uso de herramientas de lingüística de corpus. Dado que el contexto es fundamental para la identificación de los significados modales, parte del análisis de los textos requiere también la realización de análisis directo. Los resultados de este estudio sugieren que ciertamente existe variación no sólo en cuanto a las formas utilizadas en cada una de las introducciones y conclusiones, sino también en cuanto a los sentidos identificados. La modalidad deóntica en el corpus analizado se atestigua para expresar predicción, organización de los contenidos en el artículo, así como para expresar autoridad. Otro sentido evidente de los modales deónticos es el de indicar consejos que puedan resultar beneficiosos para el sector turístico.
Gen Z and Halal Local Cosmetics
Authors: Septianda Tia , Priantina Anita
Published: July 2024

This research aims to determine the influence of the halal label, knowledge and religiosity on local cosmetics labeled halal. Looking at the surrounding environment, many generation Z people still don't care about choosing local cosmetics that are labeled halal. Apart from that, this research advises consumers or cosmetic users to be careful in choosing the cosmetic brands they use, especially local cosmetics. Therefore, the author decided to conduct research on generation Z, both men and women who live in Jabodetabek. Around 112 respondents completed the survey, and data collection was done using questionnaire. The data were analyzed using software SmartPLS 3.0 with analysis method structural equation modeling (SEM). Result showed that consumers' decisions to buy are significantly and favourably influenced by the halal label. This shows that consumers are increasingly aware of the importance of choosing locally produced cosmetics that are halal certified. Further evidence of a noteworthy degree of awareness of the significance of selecting halal-labelled products comes from the significant link that exists between customers' knowledge of local cosmetics and their shopping decisions. This study suggests further exploration of the specific factors that drive the positive influence of the halal label and emphasizes the need for a deeper understanding of the complex dynamics between religiosity and purchasing decisions, thereby contributing valuable insights for industry stakeholders.

Published: July 2024

The paper examines the role of stakeholders' joint decision-making in exploiting indigenous knowledge and practices of local people to achieve sustainable food security. It assesses ways in which the collaboration of farmers and stakeholders in Uganda enhances knowledge sharing, which is vital for sustainable food security. Specifically, the study assesses the significance of indigenous knowledge in enhancing food security, the importance of joint decisions of stakeholders (farmers, community development workers, and extension workers) to food security enhancement, and the factors farmers consider when choosing indigenous/modern practices for enhancing food security. Qualitative methods of data collection were used to get views and experiences of the selected sixty-seven rural farmers in their efforts to enhance food security. Findings reveal that collaboration between farmers and stakeholders is vital for providing opportunities of sharing knowledge and experience and for determining the right combination of practices that enhance sustainable food security. The study recommends designing guidelines for routine monthly meetings between farmers and key stakeholders to share knowledge and experiences that are relevant to enhancing sustainable food security.
Impact of water scarcity on rural livelihood in the drought-prone region: A review of global perspectives
Authors: Jahura Sultana , Islam Md. Shajedul , Mostafa M. G.
Published: July 2024

Water scarcity is a challenging task for the vast majority of people in the world, which has occurred due to changes in weather patterns due to less rainfall than usual. According to perceptions, in some parts of the world, water scarcity will be more frequent and intense now. Over 200 published articles and reports from the period 2003–2023 were considered for the measurement of the global impact of water shortages on livelihoods in arid areas. Such a type of review study is designed for a systematic approach. The manuscript illustrated different dimensions of water scarcity impacts by using electronic search engines, including Google, Scopus, Science Direct, Google Scholar, PubMed, ResearchGate, and Web of Science. The study was then distinguished by including the word water scarcity with keywords such as landscape, vulnerability, adjustment, displaced person, health effect, and risk management to inquire about the necessary articles. The study results illustrated that the shortage of water during the drought period increased the misery of affected people. Droughts affect the livelihood of these people in agronomic activities, food production and security, and natural assets, causing prolonged suffering.

Published: July 2024

Panceng water is a coastal area that has quite a lot of activities, and this can trigger an increase in waste pollution. This polluting waste can cause an increase in the bioaccumulation of heavy metals in waters. Therefore, this research aims to obtain information on environmental management monitoring activities, such as water quality conditions by determining the concentration of heavy metals Pb, Cu and Zn in the roots of the Avicennia marina mangrove, water and sediment in Panceng Waters, Gresik. The method used was observation, examination of the heavy metals Pb, Cu, and Zn using ICP-MS, and the data was analyzed using quantitative descriptive methods. The results of the analysis of the concentration of the heavy metal Pb in the roots of the mangrove averaged 0.3 mg/kg, Cu 1.205 mg/kg and Zn 0.14 mg/kg. The concentration of heavy metals Pb in sediment was 5.49 mg/kg, Cu 15.7 mg/kg, and Zn 30.6 mg/kg. Meanwhile, the concentration of heavy metals Pb, Cu and Zn in sea water was not detected (ND). Overall water and sediment are still below the threshold. However, the concentration of heavy metals in the roots of the A. marina mangrove is relatively high, above the quality standards of Minister of Environment Decree No. 22 of 2021. Calculation of the level of heavy metal pollution based on Enrichment Factor (EF), Geo-Accmulation Index (Igeo) and Contamination factor (CF) values shows that the heavy metals Pb, Cu and Zn indicate levels of pollution and contamination that are still low to moderate. The Bio Concentration Factor (BCF) of A. marina in Panceng Waters, Gresik is included in the excluder category (BCF<1). The results of this research indicate that the A. marina mangrove can be developed as a phytoremediation agent because it is able to absorb and transfer heavy metals from the environment to other body tissues.

Hairdressers are exposed to volatile organic compounds (VOCs) that can pose health risks. Women of color (Black/Latina) represent nearly one-third of all U.S. hairdressers who may be disproportionally exposed to VOCs through occupational and personal use of hair products and treatments specifically formulated for this demographic. Still, data on workplace VOC exposures in this workforce remains sparse. We conducted area air monitoring of 14 VOCs in three salons serving Black women (“Black salons”), three Dominican salons predominantly serving Latino and Black women and 10 office spaces using active integrated sampling across 8-hour work shifts. Most VOCs measured were detected in hair salons (n = 13) and offices (n = 11). Salons had median VOC concentrations 2-175 times higher than offices. Among salons, 95th percentile VOC concentrations were up to 187 times higher in Black salons than in Dominican salons, suggesting that elevated exposures may occur partly from differences based on product use, services rendered, and salon characteristics (e.g., cleaning practices, ventilation). This is the first study to report indoor air concentrations of multiple individual targeted VOCs in U.S. hair salons serving women of color, highlighting the need for comprehensive exposure studies and assessment of potential health risks in this understudied and overexposed workforce.

Mathematical model of the method of autocompensation of instrumental errors of accelerometers in inertial navigation systems of a cruising mobile object
Authors: Chernyak Mykola , Lecyuk Markiyan
Published: July 2024

Instrumental additive errors of inertial sensors lead to a significant accumulation of navigation errors in a short period of time. The main method of dealing with these errors has traditionally been to use auxiliary sources of navigation information. However, the only way to increase the autonomous navigation time is to use more expensive and more accurate sensors. This paper is devoted to the mathematical model of the method of auto-compensation of instrumental errors of accelerometers of inertial navigation systems, which helps to improve the accuracy of inertial coordinate determination using accelerometers for a long battery life. The platform is offered to rotate continuously with a known angular velocity to which the accelerometers are set. This allows the instrumental additive error of the accelerometers to be modulated and navigation errors to be reduced. Analytical calculations show that the efficiency of this method increases with the battery life of the system. Experiments performed on a MEMS accelerometer unit mounted on a turntable confirm these conclusions.
Nonlinear dynamics in the primary flight control system model
Authors: Lukianov Pavlo , Pavlova Kateryna
Published: July 2024

In this paper, a mathematical model describing the flap control process of small aircraft is improved. On the basis of the analysis of existing works, the physical groundlessness of the simplification of the model of the process of primary flight control of the aircraft has been proven. An improper simplification was noted when describing the kinematics of the rod-valve system movement. The paper uses a modern approach (Stribek's friction model) to model friction in an electromechanical actuator. The given results of numerical calculations of the movement of the rod-valve system confirm the nonlinear nature of the dynamics of the "rod-valve" system.
Investigation of aroma carryover risk in a pilot plant and on industrial scale when bottling aromatised and subsequent regular wines on the same filling line
Authors: Gottmann Jörg , Müller David , Vestner Jochen , Schuster Jens , Fischer Ulrich
Published: July 2024

Aromatised wine-based beverages and regular wines are commonly bottled on the same bottling line. Sealings installed in the bottling line absorb added aroma compounds from the aromatised wine-based beverages and a subsequent release of the absorbed aroma compounds from the sealings was monitored during cleaning sequences and in subsequent products. Such unintentional carryover is associated with the risk of violating the legal ban of any aromatisation of regular wine. If cleaning is carried out according to good manufacturing practice (GMP) and traces of aroma compounds in the subsequently bottled wine show no sensory significance, this unintended aroma carryover will be considered by the German Federal Ministry of Nutrition and Agriculture as technically unavoidable and has no legal consequences. The risk of aroma absorption and aroma carryover have been investigated in different foods (orange juice, milk, and wine) and simulated in model systems using a beaker, but no real bottling scenario had been investigated till now.To fill the knowledge gap we investigated the potential aroma carryover in a pilot plant, and in two different wineries during three bottlings of aromatised wine-based beverages and subsequent regular sparkling wine. Monitoring of installed sealings revealed the uptake of seven aroma compounds and further release of aroma compounds during a recommended cleaning sequence and subsequent contact with wine. A sensory significant aroma carryover into the subsequent wine that had been circulating for 24 hours in the pilot plant was observed only for α-ionone, which exceeded its odour detection threshold in white wine after 8 hours. Regarding the three bottlings of aromatised wine-based beverages and the subsequent sparkling wine, we recorded the uptake of γ-decalactone, eugenol, and trans-cinnamaldehyde in the sealings, and their further diminishment during the implemented cleaning of the wineries and subsequent bottling of a sparkling wine. During the short residence time of the product in the bottling line, no sensory and analytical differentiation of the pre-bottled and bottled sparkling wines was observed.
Scientific creativity of Sergey P. Kurdyumov and synergetics

Published: July 2024

The theory of blowup regimes and localized non-stationary dissipative structures developed by Sergey P. Kurdyumov and his progeny received worldwide recognition. I consider the foundations of these approaches, hopes and prospects that were associated with the development of Kurdyumov’s scientific school. Time acts, on the one hand, as a creator giving birth to something new, and on the other hand as a cruel, demanding editor choosing from plans and forecasts what will become reality. If we compare a broad school of thought to a tree, this article discusses its roots, while other works in the issue the branches and leaves that have grown over the past decades.
On the Statistical Generator of Solutions to the Schrodinger Equation
Authors: Plokhotnikov Konstantin Eduardovich
Published: July 2024

The article describes the procedure for generating solutions to the Schrodinger equation by statistical testing or the Monte Carlo method. As a demonstration quantum system illustrating this generator, clusters of water: hexamer 6(H2O), dodecamer 12(H2O) and tetradecamer 14(H2O). The generator of solutions to the Schrodinger equations is derived from the algorithm proposed by the author earlier, based on the intersection of the finite-difference and Monte Carlo approaches, as well as methods of spatial reduction of scattering centers of particle nuclei and scattering centers of electrons of an arbitrary quantum system, tested on water clusters. As a result of this information, it turned out to be possible to construct an algorithm for generating an unlimited number of different spatial structures of scattering clouds of particle nuclei and electrons at the same dissociation energy of a quantum system.
STRATEGIES OF FEMALE RESISTANCE IN IBRAHIM NASRALLAH’S A'ROS AMINAH: A POSTCOLONIAL FEMINIST ANALYSIS
Authors: Ilmia Miftahul , Surur Misbahus , Mustofa Arif
Published: July 2024

This study analyses the strategies employed by female characters, particularly Aminah in Ibrahim Nasrallah's novel A'ros Aminah, to resist and challenge the oppressive characteristics of Israeli colonialism. The resistance is demonstrated by female characters in the novel from the perspective of postcolonial feminist studies. Postcolonial feminism is a multidisciplinary area of study that examines the convergence of feminist and postcolonial philosophies. The analysis centers on examining the profound impact of colonialism on the marginalization of women's dignity. This study utilizes a descriptive qualitative research methodology to analyze the behaviors and resistance of Aminah and other female characters in novel narratives. The study's data include quotations that portray the acts of resistance demonstrated by women throughout the conflict between Palestinian and Israeli soldiers. The quotes in the collection are analyzed using postcolonial feminist theory to investigate how women in the novel engage in resistance. The study findings suggest that the female characters in the novel are depicted as independent women who actively work towards their survival, possess the capability to support their families, and exhibit a distinct ability to oppose the Israeli army. The research findings indicate that women can actively resist and counteract the oppression that occurred during the conflict between the Palestinians and Israel.
RATIONAL TECHNOLOGICAL PRINCIPLES OF RECEIVING COKE WITH SPECIFIC INDICATORS OF SPECIFIC ELECTRICAL RESISTANCE
Authors: Shulga I. V. , Vladymyrenko V. V. , Lavrova I. O.
Published: July 2024

The paper presents the main technological principles of obtaining coke with two levels of given specific electrical resistance (PEO) for blast furnace and ferroalloy production, respectively. PEO is an important characteristic of coke, which is closely related to its readiness and the whole complex of metallurgical properties. As readiness increases, the electrical resistance of coke decreases simultaneously with the improvement of its consumer properties. Therefore, the specific electrical resistance determined under standard conditions is an objective characteristic of coke readiness.
On the basis of the requirements for the properties of coke of improved quality, the concept of production of high-quality coke was theoretically justified and formulated. The technological and physicochemical factors of production that significantly affect the indicators of specific electrical resistance are analyzed, such as the raw material base of coking (grade composition of the charge), regime and technological factors (temperature regime of coking, volume of the sub-vault space, speed of coking), yield of volatile substances, humidity, cohesiveness and the degree of grinding of the charge, the average reflectivity of vitrinite. Also, the quality indicators of the obtained coke are significantly influenced by the hardware and design features of coke ovens, the presence or absence of thermal preparation of the charge and coking technology (tamping, continuous layer coking).
The analysis of the technological requirements of consumers for coke with different levels of specific electrical resistance made it possible to develop rational levels of technological parameters for the production of coke with given PEO values, in particular blast furnace coke with low resistance and ferroalloy coke with high resistance, and a rational set of techniques for post-furnace preparation of coke for various directions of its use in compliance with the requirements of specific consumers. In particular, by grinding the largest (and least ready) classes of blast furnace coke, its characteristics can be improved. With the help of which the readiness and the entire set of consumer properties of blast furnace coke are evaluated. At the same time, such an operation should not be performed for ferroalloy coke, as it reduces the specific electrical resistance of coke and the efficiency of ferroalloy electric furnaces.

The features of the energy technological design of the secondary condensation unit of ammonia production are considered, in which absorption and refrigeration technological complexes (AHTK) are used for cooling circulating gas.
Defects in the functioning of AHTC have been identified, which cause violation of the cooling regime of the circulating gas under conditions of change of temperature of the atmospheric air. The article formulates the direction of research of AHTC as a technical system from the standpoint of system analysis and offers main directions of improvement, which ensure stabilization of temperature of cooling of circulating gas in evaporators at the minimum possible level, and hence, improving the energy efficiency of ammonia production.
The article provides element-by-element analysis of AHTC with definition of their useful functions and connections between them, which provided possibility of detection of undesirable effects, establishment of the main useful function and, consequently, administrative, technical and physical contradictions. The main attention is paid to the occurrence of a situation of inconsistency of the target parameter and the properties of the technical system, as well as why there are contradictory requirements to such parameter as condensation pressure. It is shown that the main useful function is essentially derived from the needs of the human operator, that is, AHTK is a subsystem relative to the anthropometric system.
Using the list of standard operators for the resolution of physical contradictions applied the operator of improvement (Q-innovation) of the technical system for the separation of contradictory properties in space and established "free" resources (R-innovation) for the implementation of the operator, which allowed for the synthesis of the new technical system AHTC. The economic efficiency of the newly built system has been determined, which is ensured by reducing the cooling temperature of the circulating gas by an average of 3 ℃. Due to this decrease, the annual operating costs of natural gas by almost 1 million. m3.

The article discusses quality assurance issues of carbon-carbon composite materials during their production stage. It emphasizes that achieving the desired quality levels of the manufacturing process depends significantly on the stages of СССМ production technology, starting from the selection and preparation of raw materials and ending with graphitization and surface treatment to improve the necessary special properties. The main characteristics of composite materials, by which СССМ can be evaluated, and key factors ensuring quality in their production are provided.
The main organizational aspects playing a key role in ensuring the quality of carbon-carbon composites production are considered. Within the scope of the study, factors of uncertainty typical for the technological process of manufacturing blanks from СССМ were identified and classified. These factors include changes in the properties of initial materials, fluctuations in the surrounding environment, as well as variations in processing and manufacturing processes. The issues regarding the quality assurance of products made from carbon composite material are discussed, which can be improved through the application of the proposed intelligent management system for the technological process of obtaining blanks from СССМ using the thermogradient method with the use of a radially movable pyrolysis zone.
The control system has been improved by introducing an additional block of a neural network adaptive controller based on a PID controller, in which the integral part is implemented as a tunable multilayer neural network, with the ability to connect and reconfigure for specific control channel inputs through parameter identification that may affect the behavior of each component.
Adding intelligent elements will help capture and formulate deterministic quality indicators for each component or for the entire system, reflecting the necessary quality characteristics.
The proposed intelligent system for automatic control and monitoring of parameters in the technological process of manufacturing products from СССМ using neural network algorithms will improve control quality by increasing the system's adaptive capabilities based on the use of macro-information about the dynamic state of the process, aimed at guaranteed quality formation of the СССМ.

Obesity is a well-documented risk factor of complications and poor patient outcomes after orthopaedic surgery. Glucagon-like peptide-1 (GLP-1) receptor agonists can be an effective way to achieve patients’ weight loss goals that are more facile than previously used weight loss avenues. Other weight loss medications and bariatric surgery have significant side effects and complications. GLP-1 has decreased cardiac morbidity and mortality, profoundly affects weight loss, and allows for better glucose control in patients with diabetes. GLP-1 should be temporarily discontinued one dose before general anesthesia due to slowed gastric emptying.
Optimizing the Assessment of Sarcopenia: Determination of Appendicular Muscle Mass Indices Correlated Best with Physical Function in Turkish Older Adults

Background
Sarcopenia, characterized by skeletal muscle loss, is assessed using appendicular muscle mass indices (ASMI), which adjusts total muscle mass in the arms and legs by dividing body mass index (BMI), weight, or height squared. Various international groups propose different ASMI for assessing sarcopenia. However, the optimal ASMI correlating with physical function in older Turkish adults remains unexplored. This study aims to determine the ASMI that most closely correlates with physical function in older Turkish adults.
Methods
The study included 326 individuals aged 60 and above. Comprehensive geriatric assessments were conducted on all participants, along with anthropometric evaluations and analyses of body composition. ASMI was calculated by adjusting height squared, weight, and BMI. Muscle strength and physical performance were assessed through handgrip strength, gait speed, and the chair stand test.
Results
The mean age was 74 ± 5.77 years. 59.8% were women and 37.5% of the patients had dynapenia. Height-squared adjusted ASMI was not significantly associated with the gait speed test or the chair stand test. However, BMI-adjusted ASMI showed significant correlations with all parameters related to physical performance (p < 0.05). Furthermore, in multivariate regression analysis, BMI-adjusted ASMI (β = 0.028, 95% CI = 0.01–0.31, p = 0.006) was independently associated with lower handgrip strength.
Conclusion
The study suggests that ASMI adjusted by BMI presents better correlations with all physical performance parameters and is independently related to dynapenia. Utilizing ASMI adjusted for BMI could enhance sarcopenia diagnosis in older Turkish adults, though further investigations are warranted.

The objective of the present study was to evaluate serum trace element and mineral levels in low- and high-productive dairy cows during feedlot and pasture periods. Serum trace element and mineral levels were assessed inductively-coupled plasma mass-spectrometry. The obtained data demonstrate that serum Ca, Mg, K, and Na levels increase significantly in the pasture period, and this increase is more evident in high-productive cows. In turn, circulating levels of B, Co, Cr, Fe, I, and Se levels were characterized by a decrease in the pasture period. Despite the lack of group differences in the feedlot period, serum B, Cr, and Fe levels in the pasture period were higher in high-productive cows. In turn, circulating Co and I concentrations in the low-productive cows exceeded those in high-productive animals. Finally, the levels of toxic trace elements in the pasture period were found to be higher in low-productive cows. Discriminant analysis demonstrated that the groups of cows with different milk productivity were clearly discriminated in the pasture but not feedlot period. In addition, multiple regression analysis revealed a significant inverse and positive association of serum Pb and Cr levels with daily milk yield. Taken together, the obtained data demonstrate that the differences in serum trace element and mineral levels between the low- and high-productive cows are more profound in the pasture period. More beneficial trace element and mineral profile in high-productive cows may hypothetically contribute to higher milk yield. However, further more detailed studies are required to elucidate the mechanisms of this association.
