Authors: Marhaendra Natawibawa
Published: August 2024

The utilization of VSD in centralized air conditioning systems has been applied for years for efficiency purposes. However, found in real implementation has not been really applied as its function yet.  This paper will present real site implementation of applying VSD on regulating the motor speed of chilled water pump as its function [1] to control the chilled water flow rate [2] go into the evaporator to let the chiller work as correspond on cooling demand at the actual load level and at its necessary power input. By analyzing some related parameters such as temperature, water pressure and amperes measured and observed to be the raw data then they will show the working performance of chiller impact on energy consumed to be evaluated on its efficiency impact.  Found the real implementation at this site the VSD does not look like varying the speed of motor pump as usually applied but more by being set at certain frequency such as 32 Hz. Then mostly the chiller cannot be run as high as cooling demand as running at only about 50-60% as lower chilled water flow rate flowing into the evaporator. Other than that it looks efficiency of refrigeration effect on handling the building load is not good enough as mentioned in catalogue/reference with difficulties on reaching the target chilled water leaving temperature.

Safe and disaster-resistant residential areas are an urgent need to reduce disaster risk. The role of the government, especially the South Tangerang City Regional Disaster Management Agency (BPBD), is very important in increasing community preparedness in a comprehensive and targeted manner. In this research, we used a qualitative method by utilizing the study literature scheme as a secondary and primary data source obtained from Scopus, Google Scholar, books, performance reports and annual final reports. Our research results show that South Tangerang City has adopted various measures to reduce disaster risk, especially through disaster risk reduction information. The government has implemented mitigation efforts, such as disaster simulations and disseminating mitigation messages through mass media and social media. Apart from that, the government is also making other persuasive efforts to change people's mindsets in realizing a culture of safety, including through habituation and increasing preparedness in disaster prevention. In this context, residential areas that dominate the spatial layout and have different facilities are the main focus. Risk zoning can be done to divide residential areas into zones with different levels of disaster risk, thereby enabling appropriate spatial planning. Early warning infrastructure also needs to be installed to provide residents with information about impending disasters and allow sufficient time to take necessary actions. Clear and well-identified evacuation routes should be provided, while green open spaces can act as "protection zones" and gathering places during evacuation. Apart from that, disaster-resistant buildings need to be considered in planning this residential area. An effective drainage system is also important to reduce the risk of flooding. Public education and awareness about disaster risks as well as regular preparedness training need to be carried out. The government needs to monitor and evaluate the mitigation measures implemented to ensure their effectiveness. Overall, this research underlines the important role of the government and BPBD South Tangerang City in reducing disaster risk in residential areas. By combining comprehensive mitigation measures and involving active community participation, it is hoped that a safety culture can be created that can increase preparedness in facing disasters

ПАТРИОТИЗМ СВЯТИТЕЛЯ ДИМИТРИЯ (АБАШИДЗЕ) КАК ЦЕРКОВНЫЙ ФЕНОМЕН
Authors: Г Д
Published: August 2024

Статья посвящена пониманию патриотизма известным церковным деятелем первой половины XX в., подвижником и миссионером святителем Димитрием (Абашидзе). Автор, опираясь на разные источники, главным образом проповеди святителя, а также учитывая мировоззренческие установки архипастыря, показывает, что патриотизм его имел глубокий, сознательный и разноплановый характер: политический, церковный, этноконфессиональный. В статье раскрываются особенности последнего, основы которого были заложены, очевидно, в детские годы. Автор считает эту форму патриотизма, любви к русскому народу, как защитнику Церкви и главной опоре государства, славянофильской, в том виде, как это понимал Н. Я. Данилевский. В статье показано, как постепенно, с начала своей архипастырской деятельности, святитель Димитрий раскрывал для себя глубину этого церковного феномена.
The article is devoted to the understanding of patriotism by the famous church figure of the first half of the 20th century, ascetic and missionary Saint Dimitry (Abashidze). The author, relying on various sources, mainly the sermons of the saint, and also taking into account the ideological attitudes of the archpastor, shows that his patriotism had a deep, conscious and multifaceted character: political, ecclesiastical, ethno-confessional. The article reveals the features of the latter, the foundations of which were laid, apparently, in childhood. The author considers this form of patriotism, love for the Russian people as the defender of the Church and the main support of the state, Slavophile, in the form as it was understood by N. Ya. Danilevsky. The article shows how gradually, from the beginning of his archpastoral activity, Saint Demetrius revealed to himself the depth of this church phenomenon.

В рецензии анализируется вышедший в 2021 г. сборник архивных документов «Из истории возрождения христианства в Осетии. 1742–1918 годы». Издание сборника было приурочено к знаменательной дате – 1100-летию крещения Алании. Особенностью данного научного труда является обращение к первоисточникам начального этапа миссионерской и просветительской деятельности Российской Православной Церкви среди горцев-осетин, а также процесса становления и функционирования церковных институтов Центрального Кавказа в дореволюционный период. С установлением первых контактов Российской империи и осетинских обществ своеобразие религиозных представлений осетинского этноса не могло не обратить на себя внимание. Православие среди алан-осетин, принявших его в X в., но позднее изолированных от других христианских государств, продолжало сохраняться в повседневной жизни, в значительной мере трансформировавшись под влиянием народных верований, приобретя черты этнизированного христианства. Рецензируемый корпус документов дает представление о том, что православное христианство для Осетии и России стало предпосылкой и средством сближения, а его упрочение – следствием интеграции региона в общеимперское пространство.
The review analyzes the collection of archival documents «From the History of the Revival of Christianity in Ossetia 1742–1918», published in 2021. The publication of the collection was timed to coincide with the significant date of the 1100th anniversary of the baptism of Alania. The peculiarity of this scientific work is the appeal to the primary sources of the initial stage of missionary and educational activity of the Russian Orthodox Church among the Ossetian mountaineers, as well as the process of formation and functioning of church institutions of the Central Caucasus in the pre-revolutionary period. With the establishment of the first contacts between the Russian Empire and Ossetian societies, the peculiarity of religious beliefs of the Ossetian ethnic group could not fail to attract attention. Orthodoxy among the Alans – Ossetians, who adopted it in the 10th century, but later isolated from other Christian states, continued to be preserved in everyday life, having been significantly transformed under the influence of folk beliefs, acquiring the features of ethnicized Christianity. The reviewed corpus of documents gives an idea of the fact that Orthodox Christianity for Ossetia and Russia became a prerequisite and means of rapprochement, and its strengthening was a consequence of the integration of the region into the common imperial space.
Rare causes of pediatric anaphylaxis due to obscure allergens
Authors: Melethil Shajitha , Yousef Ejaz
Published: August 2024

This review provides a comprehensive overview of rare causes of pediatric anaphylaxis related to obscure allergens. Anaphylaxis, a severe hypersensitivity reaction, can occur without typical symptoms, posing diagnostic challenges, especially in children. Idiopathic anaphylaxis, where no trigger is identified despite thorough evaluation, is notably challenging in this population. This review synthesizes current literature, highlighting obscure triggers such as food additives, spices like fenugreek, and cross-reactive allergens, including lupine and gelatin. These allergens are often overlooked and can lead to misdiagnosis of idiopathic cases. Understanding these uncommon triggers is crucial for clinicians to ensure accurate diagnosis and effective management of pediatric anaphylaxis, emphasizing the need for heightened clinical awareness and further research. This review raises awareness among health care providers about these lesser-known causes, aiming to improve outcomes and quality of life for pediatric patients at risk of anaphylactic reactions.

The natural environment is often contaminated with hydrophobic pollutants such as long-chain hydrocarbons, petrochemicals, oil spills, pesticides, and heavy metals. Hydrophobic pollutants with a toxic nature, slow degradation rates, and low solubility pose serious threats to the environment and human health. Decontamination based on conventional chemical surfactants has been found to be toxic, thereby limiting its application in pharmaceutical and cosmetic industries. In contrast, biosurfactants synthesized by various microbial species have been considered superior to chemical counterparts due to their non-toxic and economical nature. Some biosurfactants can withstand a wide range of fluctuations in temperature and pH. Recently, biosurfactants have emerged as innovative biomolecules not only for solubilization but also for the biodegradation of environmental pollutants such as heavy metals, pesticides, petroleum hydrocarbons, and oil spills. Biosurfactants have been well documented to function as emulsifiers, dispersion stabilizers, and wetting agents. The amphiphilic nature of biosurfactants has the potential to enhance the solubility of hydrophobic pollutants such as petroleum hydrocarbons and oil spills by reducing interfacial surface tension after distribution in two immiscible surfaces. However, the remediation of contaminants using biosurfactants is affected considerably by temperature, pH, media composition, stirring rate, and microorganisms selected for biosurfactant production. The present review has briefly discussed the current advancements in microbially synthesized biosurfactants, factors affecting production, and their application in the remediation of environmental contaminants of a hydrophobic nature. In addition, the latest aspect of the circular bioeconomy is discussed in terms of generating biosurfactants from waste and the global economic aspects of biosurfactant production.

Published: August 2024

In the construction industry, irregular schedules and long hours disrupt workers’ circadian rhythms, adversely affecting their safety and health. While studies have shown that sleep timing influences safety and health, they often overlook sleep quantity, work-shift start time, and a broad range of safety and health outcomes. To fill this gap, this study examines the relationship between circadian rhythm and safety health factors, including psychological issues, wellbeing, behavioral issues, altruistic behaviors, sleep quantity, starting hours at work, and parental care in 1,400 construction workers using a questionnaire. We investigated safety health using scales for psychological issues (0–34), wellbeing (0–24), behavioral issues (0–29), and altruistic behaviors (0–27). Midsleep time on weekends estimated circadian rhythm, with multilevel regressions adjusting for sleep quantity, work start time, and various characteristics. Results showed average midsleep at 04:11 h, with a 1 h delay associated with increased psychological issues (0.37), behavioral issues (3.0%), decreased wellbeing (0.19), and decreased altruistic behaviors (0.18). These findings highlight a correlation between early circadian rhythm and poor safety health, independent of sleep quantity and work-shift start time. Addressing circadian rhythm disruptions could be crucial for improving safety health outcomes, suggesting that work schedule adjustments and better sleep practices may mitigate adverse effects on workers’ health and wellbeing.
Articulating the supervisory functions of university supervisors in vocational education and training teaching internship
Authors: Dionne Lucie , Gagnon Claudia , Petit Matthieu
Published: August 2024

This article examines supervisory practices in vocational education and training teaching internships within a blended-learning system. Using a multiple-case study of five triads made up of a university supervisor, a cooperative teacher from the workplace and a student teacher, practices were analysed through the lens of supervisory functions: support, mediation between theory and practice, collaboration, evaluation and internship management. Findings show that support and evaluation practices are dominant within triads. The management function is characterized by practices surrounding the selection and use of digital tools to supervise student teachers in a blended-learning system. The collaboration function appears to be inconsistent from one triad to another, while the mediation between theory and practice function plays a limited role in the practices of all supervisors, despite being identified as one of their main responsibilities.

Published: August 2024

The hypometabolism induced by fasting has great potential in maintaining health and improving survival in extreme environments, among which thyroid hormone (TH) plays an important role in the adaptation and the formation of new energy metabolism homeostasis during long-term fasting. In the present review, we emphasize the potential of long-term fasting to improve physical health and emergency rescue in extreme environments, introduce the concept and pattern of fasting and its impact on the body’s energy metabolism consumption. Prolonged fasting has more application potential in emergency rescue in special environments. The changes of THs caused by fasting, including serum biochemical characteristics, responsiveness of the peripheral and central hypothalamus-pituitary-thyroid (HPT) axis, and differential changes of TH metabolism, are emphasized in particular. It was proposed that the variability between brain and liver tissues in THs uptake, deiodination activation and inactivation is the key regulatory mechanism for the cause of peripheral THs decline and central homeostasis. While hypothalamic tanycytes play a pivotal role in the fine regulation of the HPT negative feedback regulation during long-term fasting. The study progress of tanycytes on thyrotropin-releasing hormone (TRH) release and deiodination is described in detail. In conclusion, the combination of the decrease of TH metabolism in peripheral tissues and stability in the central HPT axis maintains the basal physiological requirement and new energy metabolism homeostasis to adapt to long-term food scarcity. The molecular mechanisms of this localized and differential regulation will be a key research direction for developing measures for hypometabolic applications in extreme environment.

Authors: Wu Yihan , Qin Fucang , Li Long , Dong Xiaoyu
Published: August 2024

Introduction

Creating an ecological space network is essential for safeguarding the core structure of ecological space.

Methods

Morphological spatial pattern analysis was used to locate ecological sources in the Kuye River Basin. Using the least cumulative resistance model and gravity model, the resistance surface, ecological corridor, and ecological space management network are determined.

Results and discussion

The study revealed that in 2022, the predominant land use types in the Kuye River Basin were wood land and grassland, cultivated land, and construction land. MSPA model software identifies a substantial portion of the landscape pattern as consisting of core and marginal areas, which encompass 30324.05 hm2 and 15088.24 hm2. High ecological resistance surface factors dominate the socioeconomically vibrant zone and northern regions. Resistance values ranging from 0.02 to 0.87, and high and law resistance zones alternate. The minimal cumulative resistance approach found 171 ecological corridors. And gravity model using the interaction matrix of 19 primary ecological sources discovered 8 first-level ecological corridors with the highest interaction force. There are 137 core and 23 subsidiary ecological corridors with significant affects. Overlying the road factors and ecological corridors of national highways, provincial roads, railways, and high-speed roads creates a total of 38 ecological breakpoints, each characterized by specific barrier effects and legal ecological stability.
Citizen science as a tool to increase residents’ tolerance towards urban wildlife: a case study of raccoon dogs in shanghai
Authors: Lin Huilin , Wu Di , Gu Jintu
Published: August 2024

With the increase in the number of urban wildlife, some residents feel anxious and fearful due to the presence of wildlife in urban communities, even when there is no direct physical conflict between them. This research aims to analyze the role of citizen science in increasing residents’ tolerance towards urban wildlife. This research takes the communities with the highest raccoon dog density in Shanghai as the research sites. Forty respondents were selected from local community by systematic sampling. Information was collected through semi-structured interviews and participatory observation. This research used NVivo 12 for thematic analyses. The research found that residents who did not participate in citizen science tended to take crisis observation. They regard raccoon dogs as dangerous wildlife and strictly monitor their behavior to prevent them from causing harm to humans. Residents who are engaging in citizen science tend to take scientific observations. They rationally and objectively record raccoon dogs’ behavior, numbers, and distribution. Based on the experience of scientific observation, residents who had participated in citizen science anthropomorphically observed raccoon dogs in their daily lives and established an emotional bond with them. This research found that citizen science enhances residents’ tolerance towards urban wildlife by producing knowledge and perceiving animal selfhood. In conclusion, this research reveals the complex relationship between residents and wildlife in urban communities by incorporating animals into sociological analysis.
Spatial characteristics and optimization of urban living space carbon suitability index (ULS-CSI) in Tianjin, China
Authors: Yin Zhaowei , Zhang Xiaoping , Chen Peng , Liao Qinghua
Published: August 2024

The global climate crisis is escalating, and urban living Space (ULS) is a significant contributor to carbon emissions. How to improve the carbon suitability of ULS while promoting social and economic development is a global issue. This study aims to develop an evaluation system for comparing and analyzing carbon suitability inequality and spatial differences in different areas. To achieve this goal, an urban living space carbon suitability index (ULS-CSI) based on spatial organizational index (SOI) has been proposed. The ULS-CSI was calculated at the area scale in Tianjin using information from the Tianjin Land Use Database in 2021. The carbon emissions coefficient method was used to calculate the urban living space carbon emissions (ULSCE). Moran’I and LISA analysis were used to quantify the spatial differences of ULS-CSI. The results showed that the residential living area (RLA) carbon emissions was the highest at the area scale, with carbon emissions of 1.14 × 1011 kg, accounting for 33.74%. The green space leisure area (GLA) carbon absorption was the highest at the area scale, with carbon absorption of 5.76 × 105 kg, accounting for 32.33%. SOI in different areas have spatial heterogeneity as the SOI such as building area, road network density and land use characteristics are significantly different in different areas. Areas with superior CSI were primarily situated in Heping, Hexi, Nankai, and Beichen, accounting for 83.90%. Conversely, areas under the basic CSI threshold included Xiqing, Jinnan, and Dongli, accounting for 16.10%. Spatial characteristics of ULS-CSI in Tianjin portrayed a significant spatial positive correlation, indicating the highest autocorrelation degree of CSI at 500 m, with a Moran ’I value of 0.1733. Although these findings reflect the spatial characteristics of ULS-CSI and the SOI affecting the ULS-CSI at area scale, more perfect data are needed to reflect the complexity of structural factors affecting ULS-CSI at area scale. This study is helpful for urban planning to develop differentiated carbon reduction strategies and promote low-carbon and healthy urban development.

We examined the ecological and toxicological implications of the microplastic, Cyanox®53, found in sediments and varnish clams across seven beaches in Burrard Inlet, British Columbia (BC). Using the simulation models embedded within Estimation Programs Interface (EPI) Suite™, the potential persistence, bioaccumulation, and toxicity of Cyanox®53 was assessed to evaluate the risk to varnish clams foraging on sediment containing this contaminant. Moreover, we used a bioenergetic model, based on the blue-listed surf scoter species, to estimate the risk of daily ingestion of Cyanox®53 per body weight in overwintering seabirds. Our findings indicate that varnish clams collected from Burrard Inlet accumulate on average 0.46 particles of Cyanox®53/clam, and based on bioenergetic modeling, results in surf scoters potentially consuming 78 (for males) to 83 (for females) pieces of Cyanox®53 daily from foraged varnish clams. EPI Suite™ predicted Cyanox®53 to be persistent, however, unlikely to bioaccumulate as a “traditional” chemical. Furthermore, the estimation of potential acute and chronic toxicity of Cyanox®53 to aquatic organism surrogates, such as fish, Daphnia magna, and green algae, was inconclusive due to model variability and limitations within EPI Suite™. To fully understand the potential risks of Cyanox®53 further investigation is warranted.

The sex determination system of largemouth bass (Micropterus salmoides, LMB) is XX/XY; however, the underlying molecular mechanisms involved in early sex differentiation, gonadal development, and exogenous hormone-induced sex reversal remain unknown. In this study, LMB at 15 days post-hatching (dph) were fed diets containing 20 mg/kg of 17α-methyltestosterone (17α-MT) or 30 mg/kg of 17β-estradiol (17β-E2) for 60 days, respectively. Serum steroid levels, histological observations of the gonads, and identification of sex-specific markers were employed to screen the gonads of 60-day-old normal female fish (XX-F), normal male fish (XY-M), 17β-E2 induced pseudo-female fish (XY-F), and 17α-MT-induced pseudo-male fish (XX-M) for transcriptome sequencing in order to uncover genes and pathway involved in the process of sexual reversal. The results from histology and serum sex steroid hormone analysis showed that both 17α-MT and 17β-E2 were capable of inducing sex reversal of LMB at 15 dph. Transcriptome results revealed a total of 2,753 genes exhibiting differential expression, and the expression pattern of these genes in the gonads of XX-M or XY-F resembled that of normal females or males. The male sex-biased genes that are upregulated in XX-M and downregulated in XY-F are referred to as key genes for male reversal, while the female sex-biased genes that are upregulated in XY-F and downregulated in XX-M are referred to as key genes for female reversal. Finally, 12 differentially expressed genes (DEGs) related to male sex reversal were screened, including star2, cyp17a, cyp11b1, dmrt1, amh, sox9a, katnal1, spata4, spata6l, spata7, spata18 and foxl3. 2 DEGs (foxl2a and cyp19a1b) were found to be associated with female sex reversal. The changes in these genes collectively influence the direction of sex differentiation of LMB. Among them, star2, dmrt1 and cyp19a1b with significantly altered expression levels may play potentially crucial role in the process of gender reversal. The expression patterns of 21 randomly selected genes were verified using qRT-PCR which confirmed the reliability and accuracy of the RNA-seq results. These findings not only enhance our understanding of the molecular basis underlying sex reversal but also provide crucial data support for future breeding research on unisexual LMB.

Expressed on the surface of CD8+ T cells, the CD8 co-receptor is a key component of the T cells that contributes to antigen recognition, immune cell maturation, and immune cell signaling. While CD8 is widely recognized as a co-stimulatory molecule for conventional CD8+ αβ T cells, recent reports highlight its multifaceted role in both adaptive and innate immune responses. In this review, we discuss the utility of CD8 in relation to its immunomodulatory properties. We outline the unique structure and function of different CD8 domains (ectodomain, hinge, transmembrane, cytoplasmic tail) in the context of the distinct properties of CD8αα homodimers and CD8αβ heterodimers. We discuss CD8 features commonly used to construct chimeric antigen receptors for immunotherapy. We describe the molecular interactions of CD8 with classical MHC-I, non-classical MHCs, and Lck partners involved in T cell signaling. Engineered and naturally occurring CD8 mutations that alter immune responses are discussed. The applications of anti-CD8 monoclonal antibodies (mABs) that target CD8 are summarized. Finally, we examine the unique structure and function of several CD8/mAB complexes. Collectively, these findings reveal the promising immunomodulatory properties of CD8 and CD8 binding partners, not only to uncover basic immune system function, but to advance efforts towards translational research for targeted immunotherapy.
Impact of climate policy uncertainty on corporate green investment: examining the moderating role of financing constraints
Authors: Song Yingjie , Dong Jie
Published: August 2024

Corporate green investment is the key driver for achieving low-carbon transition and sustainable marine economy. Existing literature has identified several influencing factors of corporate green investment, but there is still limited research on the relationship between climate policy uncertainty and corporate green investment. To fill this gap, this paper innovatively explores the nonlinear impact of climate policy uncertainty on corporate green investment, simultaneously focuses on the moderating role of corporate financing constraints and analyzes the coastal characteristic heterogeneity. Using the sample of listed companies in China from 2014-2020, we find that climate policy uncertainty has an inverted U-shaped impact on corporate green investment. From the perspective of heterogeneity, the inverted U-shaped effect is more significant in coastal areas. Moderating effect test indicates that corporate financing constraints strengthen the inverted U-shaped relationship and shift the turning point of curve to the left. Additionally, we further find that climate policy uncertainty has an inverted U-shaped impact on environmental performance of companies in coastal areas through green investment. Our research will provide some potential insights for China’s climate policy making and corporate green transformation, so as to contribute to sustainable marine development.

Published: August 2024

Transition metal oxides (TMOs) have emerged as promising candidates for spintronic applications due to their unique electronic properties and novel quantum states. The intricate interplay between strong spin-orbit coupling and electronic correlations in TMOs gives rise to distinct spin and orbital textures, leading to enhanced spin-momentum locking and efficient charge-spin interconversion. Remarkably, recent researches have unveiled the significant and highly tunable nature of charge-spin interconversion efficiency in TMOs, which can be manipulated through strategies such as electric field gating, epitaxial strain, and heterostructure engineering. This review provides a comprehensive overview of the recent advances in understanding the electronic band structures of TMOs and their correlation with charge-spin interconversion mechanisms. We summarize the tunability of these properties through various experimental approaches and discuss the potential implications for spintronic device applications. The insights gained from this review can guide future research efforts towards the development of high-performance, energy-efficient spintronic devices based on TMOs.

Data-driven models that act as surrogates for computationally costly 3D topology optimization techniques are very popular because they help alleviate multiple time-consuming 3D finite element analyses during optimization. In this study, one such 3D CNN-based surrogate model for the topology optimization of Schoen’s gyroid triply periodic minimal surface unit cell is investigated. Gyroid-like unit cells are designed using a voxel algorithm and homogenization-based topology optimization codes in MATLAB. A few such optimization data are used as input–output for supervised learning of the topology-optimization process via the 3D CNN model in Python code. These models could then be used to instantaneously predict the optimized unit cell geometry for any topology parameters. The high accuracy of the model was demonstrated by a low mean square error metric and a high Dice coefficient metric. The model has the major disadvantage of running numerous costly topology optimization runs but has the advantages that the trained model can be reused for different cases of TO and that the methodology of the accelerated design of 3D metamaterials can be extended for designing any complex, computationally costly problems of metamaterials with multi-objective properties or multiscale applications. The main purpose of this paper is to provide the complete associated MATLAB and PYTHON codes for optimizing the topology of any cellular structure and predicting new topologies using deep learning for educational purposes.

A leading trend in modern industry is hybrid manufacturing methods. The intention is to integrate additive and subtractive methods into a single machine. In such a process, it is difficult to evaluate the quality of the manufactured component between successive processes. A solution that would make it possible to determine the quality of a component produced by incremental technologies on the basis of forces recorded in a machining process is not yet available. In the present study, an attempt was made to reconstruct the surface of the machined workpiece solely on the basis of recorded forces during the groove micromilling process. A workpiece with a known surface geometry in the form of a sinuous wave was machined. The geometry of the workpiece corresponded to a structure typical of the selective laser sintering method for metallic powders. A process conducted with two different axial cutting depths was considered. The reconstructed surface profiles were evaluated by comparative analysis with the real machined surface.
