Authors: Santoso Allan Buddie , Madyaningrana Kukuh , Kisworo Kisworo 
Published: September 2024

<p>The increase of freshwater aquaculture leads to the increasing demand for silkworms (<em>Tubifex</em> sp) as natural feed. Unfortunately, high demand of silkworm supply is not fully fulfilled yet because its availability is relied on natural catch. Cultivation of <em>Tubifex</em> sp. outside its natural habitats requires good information on substrates and feed. We aimed to study the effect of mud, sand and their combination use as substrates in supporting <em>Tubifex</em> sp growth. This study used complete randomized design with 5 treatments, namely K1 (100% sand), K2 (100% mud), P1 (combination 75% mud-25%) sand, P2 (combination 50% mud-50% sand), and P3 (combination 25% mud-75% sand) with triplicates on each treatment. Research was conducted for 21 days using fermented chicken manure as feed. <em>Tubifex</em> sp growth was measured on biomass, number of individuals, and average body weight, while pH, temperature, dissolved oxygen and total organic matter were listed as measured environmental parameters. The use of sand and mud combination as substrate was better than a single sand or mud alone to support <em>Tubifex</em> sp growth. Combination of 75% mud and 25% sand showed the best growth of Tubifex sp as observed on biomass value of 13,244 g, 370 number of individuals, and average weight body of 2,741 mg. The application of a combination of sand and mud substrates has a potency to support the cultivation of <em>Tubifex</em> sp outside its native habitat.</p>

‘Standing with Each Other’: Indigenous-Muslim Relation-Making on Turtle Island
Authors: Hossain Memona 
Published: September 2024

Within the context of the northern part of Turtle Island, the space of relationships between Indigenous and Muslim communities is one intertwined within the history and geopolitical realities of settler-colonialism and immigration. This paper is an exploration of the theme of space, and relationship formation from the perspective of Muslim and Indigenous peoples in Canada who have engaged in building relations over the past two decades. This article is based on a wider qualitative semi-structured interview-based research project, supported by content analyses of existing literature and online resources produced by relevant organizations and initiatives. The research analysis has led me to thematically organize these spaces into four general types of spaces: 1) organization-led spaces of relationship building; 2) spaces of conviviality as pathways to relationship building; 3) relational spaces defined through acts of documentation; and 4) spiritually and emotionally bonded spaces that transcend a secular framework. This analysis led to identifying practices of relational meaning-making that form a preliminary understanding of what characterizes Indigenous-Muslim relations on Turtle Island.

Published: September 2024

The results of a comprehensive clinical, radiological and neurophysiological study were analyzed in patients with kyphotic deformity of the thoracic and lumbar spine due to a congenital anomaly of vertebral development in the dynamics of surgical treatment. It has been established that congenital kyphotic spinal deformity is accompanied by vertebromedullary conflict with a high risk of the occurrence and/or worsening of spinal neurological disorders. The study of the data obtained made it possible to evaluate deformation lesions of the spine from the standpoint of qualitative and quantitative severity of pathological changes in the conduction function in the system of nervous tracts of the spinal cord, which was an objective argument in justifying the indications for surgical correction and its methodological implementation, as well as an important neurophysiological criterion for subsequent dynamic monitoring of clinical conditions of a patient.It was found that the surgical treatment allowed us to improve and subsequently stabilize the functional state of the spinal cord as a consequence of the achieved significant correction of congenital kyphotic spinal deformity.

Published: September 2024

The concentration of free amino acids in the skin of rats in experimental acute allergic contact dermatitis (ACD) was studied. Free AAs were determined by reverse-phase high-performance liquid chromatography. Acute ACD was simulated using 2.4-dinitrochlorobenzene. The levels of asparagic and glutamic acids, valine, leucine, phenylalanine, lysine, and taurine increased and methionine, tyrosine, tryptophan, α-aminobutyric acid and anserine decreased in the rat skin during acute ACD development. An imbalance of amino acid metabolism was expressed in an increase in the ratio of aromatic amino acids/branched-chain amino acids by a decrease in the sum of aromatic amino acids. An increase in the Phe/Tyr ratio may indicate a decrease in the activity of the hydroxylase pathway of phenylalanine metabolism in the rat skin. Only in the skin of rats with acute ACD, the levels of valine, isoleucine and lysine were negatively correlated with the level of blood TNF-1α, which confirms their anti-inflammatory effect.Histological examination revealed an inflammatory reaction expressed by lymphocytic infiltration of various skin layers (ectoderm, subepidermal layer). Perivascular proliferation of fibroblasts and formation of subepidermal fibrosis were observed in subepithelial sections. The upper layer of the thorny layer was necrotic, the granular layer with necrosis and pronounced karyopiknosis of nuclei was observed. The epidermis thickness increased, infiltration of lymphocytes and segmented neutrophils into epidermis was noted up to the cells of the thorny layer (exocytosis).The data obtained indicate a significant metabolic imbalance of amino acids in the skin of rats in acute ACD, manifested by depletion of the amino acid pool of aromatic and sulfur-containing amino acids, impaired metabolism of phenylalanine, as well as increased levels of immunogenic amino acids that play a functional role in the regulation of anti-inflammatory, antioxidant system and proliferative activity of immune system cells on the background of a significant inflammatory process.

Published: September 2024

Abstract
In an increasingly competitive global automotive landscape, the strategic integration of Total Quality Management (TQM) and Lean Practices (LP) has emerged as a crucial determinant of operational excellence and sustained organizational performance. Grounded in empirical evidence from the Thai automotive sector, this study explores the intricate synergies between TQM with Malcom Baldrige National Quality Award (MBNQA) dimensions, lean implementation, and firm performance. This study employs the quantitative research method, where the measurement scales for each construct were adopted from the literature and reviewed by academics. Data were collected from 854 manufacturing firms in Thailand through a mail survey method. This study applied a two-step structural equation modeling (SEM) process. The findings reveal a robust direct effect of TQM (leadership, strategy planning, customer and workforce focus) on firm performance, underscoring its pivotal role. Notably, TQM also exhibited a substantial indirect effect on business performance, mediated sequentially through lean practices including continuous flow, 5S, and total preventive maintenance. Lean practices similarly demonstrated significant direct and indirect effects on firm performance. Collectively, the combined effects of MBNQA and lean practices on firm performance was also observed, substantiating their complementary contributions. These findings hold significant implications, both from an academic and a practical standpoint. From a theoretical perspective, this research enriches the discourse by providing empirical insights into the mediating roles of lean practices, elucidating the paths through which TQM's performance-enhancing effects can be transmitted. Concurrently, the magnitude of the impact these practices have on firm performance underscores their practical relevance, and insights derived from this study could play a key role in guiding automotive firms and suppliers to align critical components to drive performance excellence.
Application of Metaheuristics for Multi-Trip Capacitated Vehicle Routing Problem with Time Window
Authors: Niyomphon Kantapong , Nakkiew Warisa 
Published: September 2024

Abstract
This study focuses on the delivery routing problem faced by a transport company located in Phuket, Thailand. The goal of this study is to find a daily optimum route in order to minimize the total transportation cost, which comprises fixed costs associated with vehicle rental and variable costs calculated based on factors of travel distance, fuel prices, and fuel consumption. The complexity of this problem is compounded by the fact that customer demand often exceeds a vehicle capacity, in terms of weight and volume. In addition, delivery must be made within specific time windows. To tackle this issue, the delivery routing problem is classified as a multi-trip capacitated vehicle routing problem with time window (MTCVRPTW). Since the problem is NP-hard, an application of metaheuristic is more practical to determine the delivery routing of the company within a reasonable computing time. In this study, Particle Swarm Optimization (PSO) and Differential Evolution (DE) algorithm are applied to solve MTCVRPTW. The numerical results show that DE provides better solution quality compared to those obtained from PSO and company current practices.

Authors: Garbier Milan , Čorejová Tatiana 
Published: September 2024

Abstract
Battery energy storage systems (BESS) are becoming increasingly important and their number of applications in energy systems is constantly increasing. Although batteries cannot solve the problem of electricity storage in the long term, BESS systems have proven to be suitable for short-term provision of flexibility within the day. Their real usability is shaped by the provision of balancing services to ensure a stable supply of electricity in distribution networks. BESS systems were able to respond to the dynamic development of the electricity market in recent years and achieve excellent results from the point of view of economic return. The aim of the contribution is to present the results achieved in selected cases of BESS use and to determine their economic return. The size of the battery (installed power and capacity) is designed to be able to work in individual modes and operating cases. A critical element for the design of the battery size is the technical conditions for the provision of balancing services. On the basis of market research, we determine the costs of acquiring and operating the battery, including the need for a software superstructure for controlling the battery itself and ensuring the necessary business functions. According to the defined criteria, we evaluate the technical operation of the battery located at the point of consumption (behind the meter) using the battery model in several operating cases. Subsequently, we analyse its sales based on the development of market prices and the conditions in which the battery is placed.

Published: September 2024

Abstract
Additive manufacturing and topology optimization provide new possibilities to produce complex parts. They can be used separately but with joint applications as a mutually reinforcing solution in component development tasks. The results obtained using the design software can be refined even further depending on the specific goal set. This paper deals with mass reduction with stiffness-based topology optimization of a structural component. The effect of different design spaces, load cases, and design parameters were examined. Then, the new part was validated with FEA simulation. After the validation, the part was prepared for 3D metal printing. Based on the research results, we present a methodology that can be used as a solution considering the software’s limitations and the development of the specific component. Applying the methodology developed in the research makes it possible to achieve mass minimization on other parts with a similar method.

Abstract
The paper presents the results of contact strength and tribological property tests of spare parts made of a popular resin using a 3D DLP printing technology. Two printer models by the same manufacturer were used in the study. The post-processing technique, which shapes the final functional properties, was diversified. Surface performance properties were compared, i.e. Shore hardness, indentation hardness, Martens hardness, elastic modulus, and parameters related to surface creep and relaxation. Tribo-logical durability in rotary motion and tribological wear in reciprocating linear motion were also evaluated using micro- and nanotribometers. This was followed by surface analyses of the friction track of the analysed materials using microscopic methods: a scanning electron microscope, a WLI interferometric microscope, and an optical microscope. The results were statistically processed and the relationship between the parameters determined in the indentation test was determined.

Published: September 2024

Abstract
Demand-Driven Material Requirements Planning (DDMRP) is an emerging inventory management approach that has garnered significant attention from academia and industry. Numerous recent studies have highlighted the advantages of DDMRP compared to traditional methods such as material requirement planning (MRP), Theory of constraint (TOC), and Kanban. However, the performance of DDMRP relies on several parameters that affect its effectiveness. Parameterization models and the optimization of control variables have significantly contributed to the field of inventory management and have proven to be effective and practical in addressing challenges by providing a structured approach to handling complex variables and constraints. This paper introduces an innovative parameterization model that leverages deep reinforcement learning (DRL) to parameterize a DDMRP system in the face of uncertain demand. The main objective is to dynamically determine the optimal values for the variability and lead time factors within the DDMRP framework, to maximize customer service levels and optimize inventory efficiency. The results of this study emphasize the effectiveness of DRL as an automated decision-making approach for controlling DDMRP parameters. Additionally, the findings highlight the potential for enhancing the performance of the DDMRP approach, particularly in terms of on-time delivery (OTD) and average on-hand inventory (AOHI) by adjusting the variability and lead-time factors.
