Discursive valuing practices at the periphery: Javanese use on Indonesian youth radio in multilingual Solo
Authors: Dewi Udiana Puspa , Goebel Zane 
Published: September 2023

AbstractThis paper seeks to understand how languages are discursively identified and valued within a youth radio station in Solo, Indonesia. This study seeks to contribute to the body of knowledge on the dynamic relationship between the national language, Bahasa Indonesia, and the local language, Javanese, by utilizing a social value and centre-periphery lens to approach continuity and change in present-day Central Java. Valuing practices are observed by examining the situated use of linguistic features and norms of their use within specific social practice (radio programming). From June 2020 to July 2020, a total of 120 h of radio content was recorded for analysis. Analysis showed that valuing practices emerged in response to the use of linguistic features within different radio segments of the program. The formation of participatory frameworks in the periphery and the evaluative commentaries accompanying them contributed to the construction of norms for using these linguistic features. Our analysis shows how paying attention to evaluative practices can highlight how the value of sets of linguistic features emerge, circulate, and are transformed within the media practices in the periphery.
“I know how to improve. You know what I mean?”. Neoliberalism and the development of multilingual identities through study abroad
Authors: Mocanu Vasilica 
Published: September 2023

Abstract
The present article examines the relationship between study abroad and the construction of multilingual identities regarded as more marketable in the neoliberal economy. The main objective is to provide an insight on student mobility and dominant visions of the future in line with which languages are chosen to be taught/learned at tertiary level and how this offer mirrors the economized perspective adopted in the higher education system. It focuses on European higher-education students participating in study abroad through the Erasmus program in three contexts across Europe (Finland, Romania, and Catalonia). In the first place, the article delves into the ways neoliberal discourses on the value of study abroad and the skills that are expected to be acquired through the experience – this is, the type of individuals that the participants might become – shape their decision to enroll in a sojourn abroad in a particular context. Secondly, this article analyzes to what extent European youth participating in study abroad eventually perceive they added to their identities the desirable marketable skills they expected and how they consider this is going to materialize in the future. By looking at how multilingual identities are constructed through the Erasmus program, this study hypothesizes that study abroad is another mechanism embedded in educational practices that respond to economic demands in which the marketization of language skills plays a prominent role.
Kant’s Hylomorphic Formulation of Right and the Necessity of the State
Authors: Gregory Michael 
Published: September 2023

AbstractThis paper argues against the common justification for the necessity of the state through the particular difficulty of private property right. Instead, I argue that the necessity of the state is internal to the concept of right in general. In order to show this, I point out how Kants adoption of hylomorphic language for the concept of right, where there is a formal and material aspect of right, allows us to understand theRechtslehreas progressing through a syllogistic deduction from innate right (major), private right (minor) to public right (conclusion). Material right is made necessary through its subsumption under formal right in the civil condition.
Finite spectrum of fourth-order boundary value problems with boundary and transmission conditions dependent on the spectral parameter
Authors: Zhang Na , Ao Ji-jun 
Published: September 2023

Abstract
A kind of fourth-order boundary value problem with eigenparameter-dependent boundary and transmission conditions is investigated. By constructing the characteristic function, we prove that the problems consist of a finite number of eigenvalues. We obtain that the number of eigenvalues of the problems not only depend on the order of the equation but also depend on the partition of the domain interval, the boundary conditions, and the eigenparameter-dependent transmission conditions.

Abstract
The dissipative Kerr soliton combs based on microresonators have attracted wide attention due to their high coherence and on-chip integration. Meanwhile, the soliton microcombs have shown broad applications in coherent communication, on-chip low-noise microwave synthesizer, optical clock, etc. However, the performance of these applications is typically limited by their bandwidth as the precise tuning of the soliton microcombs usually relies on the thermoelectric cooler, which is slow and may increase the system’s complexity. Here, we demonstrate the observation of dissipative solitons based on the magnesium fluoride resonator with an ultrahigh-quality (Q) factor of about 927 million. The ‘power-kicking’ scheme is employed to lock and stabilize the solitons actively. Also, tuning the acousto-optical modulator allows changing the bandwidth and recoil of the solitons. This approach enables more direct and concise feedback and reduces the system’s complexity.

Abstract
Black rice (Oryza sativa L.) is a rich source of phenolics and anthocyanins. It was aimed to investigate the effect of different extraction methods such as conventional solvent extraction, ultrasound-assisted extraction (UAE), and microwave-assisted extraction (MAE) on antioxidant activity and phenolic profiling of black rice free, esterified, and bound phenolics fractions. Spectrophotometric methods were used to evaluate antioxidant activity and HPTLC was used for phenolics profiling. The highest content of % yield, total anthocyanin (TAC), total phenolic (TPC), and total flavonoid (TFC) contents were detected in MAE. It was also observed that antioxidant activity based on DPPH, ABTS, superoxide radical-scavenging and ferric reducing antioxidant power (FRAP) assays showed highest activity in MAE. Eight phenolic compounds were identified and quantified by a validated HPTLC method. MAE showed most abundant phenolic compounds. A significant positive correlation was established between % yield, total phenolic content, and total flavonoid content (p < 0.05) where a significant negative correlation was established between % yield, TPC, and TFC with IC50 of antioxidant activity (p < 0.05). Diverse phenolic contents and antioxidant activity were studied with different forms of phenolics with the different extraction methods. It designates that the extraction techniques had effects on the bioactive compounds as well biological properties.

Abstract
Visible light active, highly stable, nontoxic, and efficient photocatalysts based on 1 %, 3 %, and 5 % Mn@Co3O4 were synthesized and functionalized with reduced graphene oxide. The X-rays diffraction (XRD) spectroscopy and FT-IR spectroscopy were employed for structural and functional group studies. Under visible light irradiation, photocatalytic activities of 1 %, 3 %, and 5 % Mn@Co3O4/rGO nanocomposites were studied for the degradation of organic pollutant methylene blue. Almost 85.4 %, 90.2 %, and 93.4 % degradation of methylene blue were observed after 80 min with 1 % Mn@Co3O4/rGO, 3 % Mn@Co3O4/rGO, and 5 % Mn@Co3O4/rGO respectively. The prepared nanocomposites followed pseudo-first-order kinetic studies. Among all samples, the 5 % Mn@Co3O4/rGO showed maximum degradation of 93.4 % in 80 min. Moreover, 5 % Mn@Co3O4/rGO nanocomposite maintained its excellent dye degradation ability even after three cycles.

When choosing between rewards that differ in temporal proximity (intertemporal choice), human preferences are typically stable, constituting a clinically relevant transdiagnostic trait. Here we show, in female and male human patients undergoing deep brain stimulation (DBS) of the anterior limb of the internal capsule/NAcc region for treatment-resistant obsessive-compulsive disorder, that long-term chronic (but not phasic) DBS disrupts intertemporal preferences. Hierarchical Bayesian modeling accounting for temporal discounting behavior across multiple time points allowed us to assess both short-term and long-term reliability of intertemporal choice. In controls, temporal discounting was highly reliable, both long-term (6 months) and short-term (1 week). In contrast, in patients undergoing DBS, short-term reliability was high, but long-term reliability (6 months) was severely disrupted. Control analyses confirmed that this effect was not because of range restriction, the presence of obsessive-compulsive disorder symptoms or group differences in choice stochasticity. Model-agnostic between- and within-subject analyses confirmed this effect. These findings provide initial evidence for long-term modulation of cognitive function via DBS and highlight a potential contribution of the human NAcc region to intertemporal preference stability over time.SIGNIFICANCE STATEMENTChoosing between rewards that differ in temporal proximity is in part a stable trait with relevance for many mental disorders, and depends on prefrontal regions and regions of the dopamine system. Here we show that chronic deep brain stimulation of the human anterior limb of the internal capsule/NAcc region for treatment-resistant obsessive-compulsive disorder disrupts the stability of intertemporal preferences. These findings show that chronic stimulation of one of the brain's central motivational hubs can disrupt preferences thought to depend on this circuit.

Agony to Enlightenment: Parallels between Rafael Lechowski’s Quarcissus and T.S. Eliot’s Four Quartets
Authors: Saravia Vargas Juan Carlos , Saravia Vargas José Roberto , Delgado Solano Daniel 
Published: September 2023

Eliot’s Four Quartets stands as one of the most influential poetic works of the 20th Century. Therefore, academics have approached it from many different angles, among which one may mention its musicality, the references it contains, its composition, and the belief systems that converge in it, such as Christianity, Hinduism, and Buddhism. Rap music, on the other hand, is generally assumed to be a cultural product that lacks profound insights on the subjects it touches upon precisely because it is built for entertainment, not academic analysis. However, although rap music is generally regarded as non-academic, Rafael Lechowski’s extensive rap work entitled Quarcissus: El arte de desamar has divided criticism because of the way in which it engages with the subject of emotional pain. This article argues that Lechowski’s work shares both structural and content features with Eliot’s Four Quartets; particulary regarding Buddhist principles, which is established by comparing the four sections that make up both texts.

The result of the research is the development of a technology for the production of germinated flaxseed using plasma-chemically activated aqueous solutions. The object of research was flaxseed. An urgent technological problem is the intensification of the bioactivation process of flaxseed and its effective disinfection. The expediency of using plasma-chemically activated aqueous solutions as an intensifier of the process of flaxseed germination and an effective disinfectant of food raw materials was experimentally proven. It is shown that the use of plasma-chemical activation of process solutions not only accelerates flaxseed germination, but also contributes to a more active accumulation of biologically valuable components in flax raw materials. The composition of flaxseed as a raw material derivative was analyzed. Germinated flaxseed, which is considered a high-value component of food products, was studied separately. An increase in the moisture content of flaxseed during the soaking process by 0.7–1.7 % was recorded. Seedling development increases by 2–9 mm. The germination energy and capacity increase by 5–12 %. The biomass of germinated seeds increases by 39–56 %. In the process of germination, the content of proteins in flaxseed increases from 21.88 to 23.71 %, reducing sugars from 2.37 to 4.02 %. The total content of amino acids increases from 3.64 to 10.38 % compared to the control, and 10 times compared to the raw material. A significant accumulation of vitamins was noted: B1, B2, B3, B5, B6, B7, B9, C, E. In addition, plasma-chemically activated solutions effectively disinfect germinated flaxseed.
The technology can be applied in the production of enrichment components of food products. The developed technology will receive special attention in the production of functional food products

The paper presents the results of experimental studies of concrete and compressed reinforced concrete elements from cementless claydite-concrete. An experimental study of reinforced concrete elements with central and eccentric application of forces was carried out to determine their increased sensitivity. The construction material is cementless expanded clay concrete, obtained by a mixture of finely divided granular electrothermophosphorus slag. The tests were carried out on reinforced concrete compressed elements with central and eccentric application of longitudinal force to determine their bearing capacity. According to the test results, the strength and deformation properties of new concrete on a glass-slag binder and the calculation of reinforced concrete structures are checked.
The selection of compositions of glass-slag claydite-concrete of various grades has been made. The use of concrete with a clinker-free binder in construction makes it possible to reduce the need for a scarce building material – cement.
Studies of the physical and mechanical properties of glass-slag expanded clay concrete grades M50+M150 with a bulk density of 1,000–1,400 kg/m3 were carried out under a short-term static load. At the same time, the strength and deformation properties of glass-slag expanded clay concrete were studied under short-term action of compressive and tensile loads.
The use of any new building material must be preceded by a comprehensive study of it – determination of its strength properties, study of concrete in the structure under load, etc.
Building codes and regulations are adopted for the standard construction material, the properties of aggregates are not taken into account. Our studies show that the properties of fillers increase the strength properties of the structure when using claydite concrete on a glass-slag binder in reinforced concrete structures

Distributed Denial of Service (DDoS) attacks is a problem in computer networks. DDoS attacks pose a significant threat to internet networks as they cause congestion and disrupt the optimal functioning of servers. Detecting the source of these attacks is essential for effective protection. Therefore, in this study, we propose a hybrid strategy that combines Suricata, an intrusion detection system (IDS), with pfSense, a firewall, to address DDoS attacks. Suricata, the IDS, can identify the destination of the attack, which allows pfSense, the Firewall, to block the attack by dropping packets sent by the attacker. As a result, by leveraging this combined approach, we have observed significant improvements in the quality of service (QoS). The results of our study indicate a 1.08 % increase in throughput value, from 1881.97 bytes to 902.44 bytes, demonstrating improved efficiency in data transmission. Additionally, we observed a 57.32 % increase in the average total number of packets sent, from 1382 packets to 3238 packets, indicating better network performance. Furthermore, the proposed strategy significantly reduced delay and jitter values. The delay value decreased by 88.78 %, from 90.76 ms to 10.18 ms, and the jitter value decreased by 88.99 %, from 181.85 ms to 20.03 ms. These improvements signify a notable reduction in latency and packet timing variations, leading to a smoother network experience. Another crucial aspect we evaluated was the CPU utilization. The proposed strategy resulted in a substantial decrease in CPU utilization by 81.23 %, from 78.3 % to 14.7 %. The combination of pfSense and Suricata has proven to be a successful approach, providing robust protection against DDoS attacks, including those utilizing IPv6. This research can be implemented as a solution on a campus ad-hoc network with limited computers

Persimmon fruits (Diospyros kaki L.) attract the attention of researchers due to their high nutritional and medicinal value. The composition of persimmon is rich in nutrients. The object of research is the storage technology of persimmon. Fully ripe persimmon varieties Khachia and Khiakume were used as research material. If the activity of enzymes is inhibited or reduced during refrigerated storage using a controlled gas environment, then the consumption of nutrients for respiration will decrease, and the fruits will retain their original appearance. The persimmon varieties used were stored in refrigerators for 5 months in five variants. In persimmon fruits of both varieties, quantitative changes in the main indicators during refrigerated storage were studied. The regularities of changes in the activity of enzymes of the oxidoructase class depending on the composition of the controlled gas medium and the content of phenolic compounds were considered.
As a result of the analyzes, a rational regime for storing persimmon varieties in a refrigerator under CGE conditions with a gas composition of 3–4 % CO2 and 2–3 % O2, a temperature of ‒2...–3 °C and an air humidity of 90–95 % was determined. During the storage period, the activity of all enzymes, except for ascorbate oxidase, completely ceased (except for the catalase enzyme in the Khachia variety). During long-term storage of the Khachia variety in a refrigerator, the activity of the enzyme ascorbate oxidase decreased by 94 %, o-diphenol oxidase and peroxidase decreased by 100 %, catalase by 95.5 %. Ascorbate oxidase activity decreased by 94.5 % in persimmon fruits of the Khiakume variety, and the activity of other enzymes was completely inhibited. To achieve this result, it is important that the activity of oxidoreductases decreases or passes into an inhibitory state. The results make it possible to regulate the quality indicators of persimmon varieties depending on their storage modes and use them to provide people with fresh fruits not seasonally but for a long time
