Assurance of peace and security of the mankind is the most important task of modern international law. It is no coincidence that international law is called the law of peace. The United Nations Charter has declared global peace, security, human rights and development as unconditional priority values that constitute procedural and substantive grounds for the international law and order. The main task of the world community is to prevent the revival of fascism.

Adolescence is characterized as transitional, rather difficult, complex, critical and has a major significance in the formation of a person’s personality: the scope of activity expands, the character changes qualitatively, the foundations of behavior are laid and moral ideas are formed. This article discusses the features of the development of adolescents in conditions of family deprivation. After all, it is the family that influences the formation of the child’s personality. Preventive measures are also proposed that will help eliminate the deviant behavior of adolescents in conditions of family deprivation.

Published: June 2023

Background: Cercospora leaf spot of mothbean caused by Cercospora canescens Ellis and Martin is one of the most important fungal diseases causing damage to the crop. C. canescens causes losses to yield in major Mothbean growing areas of Rajasthan. Its affects the foliation and in severe infection damaged entire crop that lead to yield loss up to 50-70%. In this, Check the efficacy of new molecules available in the market should be analyzed with this disease. Methods: Nine fungicides were tested at four concentrations (50, 100, 150 and 200 ppm) under in vitro conditions with CRD design against C. canescens and also tested under field conditions. The field experiment was conducted at Research Farm of College of Agriculture, SKRAU, Bikaner, during Kharif 2019 in RBD design with the application of foliar spray of nine different fungicides at different concentrations against Cercospora leaf spot disease of mothbean. Result: Among these new molecule fungicides tested, trifloxystrobin 25% + tebuconazole 50% WG and carbendazim 12% + mancozeb 63% WP was highly effective with maximum inhibition of mycelial growth (100.00%) at 200 ppm concentrations. The results of in vivo studies revealed that spraying with 0.15% trifloxystrobin 25% + tebuconazole 50% WG helped to manage the leaf spot successfully and reduced the disease intensity (15.51%) with disease control (72.71%) and recorded highest yield (8.10 q ha-1) effective under field conditions as foliar spray at appropriate time.

Authors: Cross Lisa A. , Koren Ainat , Dowling Jacqueline S. , Gonzales Joseph E.
Published: June 2023

Background:Compassion fatigue is a negative consequence impacting caregivers of chronic illness, such as heart failure. Reliance on family caregivers is expected to rise, placing importance on recognizing family caregiver characteristics that contribute to compassion fatigue.Purpose:This study specifically examined the associations of characteristics of family caregivers caring for end-stage heart failure, compassion satisfaction, social desirability, and the family caregiver–nursing provider relationship on compassion fatigue.Methods:An adapted interaction model of client health behavior guided this cross-sectional survey, which comprised a demographic questionnaire, the Professional Quality-of-Life Scale, the caregiver–provider relationship assessment, the Marlowe–Crowne Social Desirability Scale Short Form (Form C), and the Bakas Caregiving Outcomes Scale.Results:There were 127 family caregivers (FCGs), primarily those who have been a caregiver for longer than 1 year (78.4%), who completed the entire survey. Increased compassion satisfaction and positive caregiving effects were associated with decreased compassion fatigue (p< .001), while increased social desirability was associated with increased compassion fatigue (p< .001). A positive family caregiver–nursing provider relationship was related to decreased compassion fatigue (p< .001). More compassion fatigue was seen with lower spiritual status (p< .001).Implications:The chronic progression of heart failure presents opportunities for nursing providers to assess caregivers and offer frequent interventions. Family caregivers may not ask for help. Nursing providers must foster relationships with family caregivers to prevent negative consequences and mitigate compassion fatigue. Future research on the nursing provider relationship and FCGs is needed.
“The Person Gets Lost in the Whole Process”: Access to Physical Healthcare for Patients Hospitalized in a Psychiatric Hospital
Authors: Domingue Jean-Laurent , Jager Fiona , Lusk Jodi , Ezeani Celestina , Pryer Billie , Davis Sascha
Published: June 2023

Background and Purpose:Persons living with mental illnesses have unmet physical healthcare needs, leading to premature death. When they attempt to access physical health services, they are faced with numerous barriers that lead to delays in care. Although mental health nurses are identified as being essential actors in helping persons with mental illnesses navigate the complexities of the healthcare system, they also engage in conduct that further stigmatizes them. To complicate matters more, mental health nurses themselves face stigmatization when they help their patients living with mental illnesses access physical healthcare services. The aim of the study was to explore mental health nurses’ experiences of associative stigma when accessing physical health services for their patients.Methods:To achieve this aim, we used an interpretive phenomenology methodology and a theoretical framework rooted in Erving Goffman’s notion of associative stigma. Specifically, we conducted six interviews with mental health nurses working at an urban multisite psychiatric hospital to elicit accounts of their experiences of associative stigma when seeking physical healthcare for their patients and the meanings they make of these.Results:The results presented in this article illustrate some of the mechanisms by which stigmatization toward persons living with mental illnesses and mental health nurses cause delays in physical healthcare accessibility.Implications for Practice:In our discussion, we highlight the implications of these results for the practice of nurses and propose two structural solutions to improve access to physical healthcare and reduce stigmatizing experiences.

Published: June 2023

Social determinants of health (SDOH) may significantly impact treatment outcomes for depression in primary care. An analysis of patients in collaborative care was conducted to explore the association between SDOH and depression baseline scores and treatment outcomes as assessed by the Patient Health Questionnaire-9 (PHQ9). Although individuals’ baseline PHQ9 scores did not differ by SDOH flag, there was a direct effect of SDOH on PHQ9 reduction rates. SDOH did not significantly moderate the association between collaborative care treatment and depression outcomes. Individuals flagged with SDOH showed higher depression scores at the end of the treatment despite a higher clinical dosage. Routine screening for SDOH in collaborative care and primary care should be further explored.

The vicious cycle of racism, low self-efficacy, and dependency: First generation immigrants’ maternal involvement in their children’s education in the context of South Korea
Authors:   Korean Comparative Education Society, Park Heejin
Published: June 2023

[Purpose] This study intends to understand the characteristics of first generation immigrant mothers’ involvement in their interracial children’s education in South Korea.
[Methods] Semi-structured interview was adopted as a principal data collection method, which included twenty first immigrants and ten native Koreans related tothem.Allresidedinaruralcountywhichwasselectedasacaseforthefieldwork.
[Results] In contrast to the popular stereotype of immigrant mothers and their families-that they are uninterested in their children’s education-most mothers showed high aspirations and expectations regarding their children’s education. However, as in previous studies, not all of the high maternal aspirations are actualized through their daily involvement in their children’s education. This disconnect between aspirations and behavior has not yet been explained substantially in the literature: that is, a vicious cycle of the low self-efficacy, dependency, limited maternal involvement in their children, and the ensuing misunderstandings of those mothers.
[Conclusion] Through this study, it can be confirmed that in order to improve the quality of immigrant mothers’ maternal involvement in their children’s education, breaking the vicious cycle caused by the prejudice and misunderstanding of immigrant mothers in Korean society and widespread racial discrimination is the top priority.
The implications of ‘May 4, 1970 and its aftermath’ for citizenship education in the United States and Korea: “The constitutional rights against national security ideology”
Authors:   Korean Comparative Education Society, KIM Min Ho
Published: June 2023

This study aims to analyze the influence of the ‘May 4, 1970 Kent State Shootings and its aftermath’(Ma4a) on citizenship education in American high schools and to identify implications for the institutionalization of movement-oriented citizenship education in Korea. The data were analyzed using the methodology of ‘qualitative content analysis.' The data on Ma4a was collected by visiting the ‘May 4 Site,’ ‘May 4 Visitors Center,’ and ‘May 4 Digital Archive’ at KSU in 2021 and 2022. It was also useful to refer to the undergraduate course on Ma4a. The data on high school citizenship education in the United States were collected from Ohio Curriculum Standards of social studies, history textbooks, and teachers’ lesson plans. ‘May 4, 1970’ was described as “civil disobedience” rather than “riot” in social studies curricula, history textbooks, and lesson plans after its institutionalization from the late 1990s to the early 2000s. The constitutional right of ‘freedom of speech and assembly’ was not undermined by the ‘national security ideology.’ However, after the events of September 11, 2001, and the 2008 economic crisis, the Ohio Department of Education described the people's right to protect themselves from only “undue” governmental interference. The paradigm of citizenship education in U.S. schools changed due to the contest between state-centric citizenship and participatory citizenship. Social movements influenced citizenship education through the institutionalization of movement knowledges by movement intellectuals, which took a lot of time. This study has implications for the institutionalization of movement-oriented citizenship education, such as ‘Jeju 4·3 education for peace and human rights’ in Korean schools.

A tanulmányban a hazai villamosenergia-rendszer terhelésének előrejelzési bizonytalanságát vizsgálom, Gauss-keverékregresszió (Gaussian Mixture Regression) felhasználásával. A rendszerterhelés heteroszkedasztikus viselkedésének leírása a Gauss-keverékmodellre (Gaussian Mixture Model) épülően kézenfekvő, azonban az energiaszektort érintő szakirodalomban elsősorban a nemlineáris (és interakciós) kapcsolatok modellezésére történő alkalmazása szerepel. Ez többek között azzal magyarázható, hogy a villamosenergia-fogyasztás bizonytalanságának explicit modellezése iránti igény az elmúlt években jelent meg igazán markánsan. A tanulmányban bemutatom, hogy a Gausskeverékregresszió mennyire jól megragadja a villamosenergia-rendszer terhelésének előrejelzési bizonytalanságát, ami a várható értékhez hasonlóan szintén erős szezonális viselkedést mutat. A számítások implementálása a nyílt forráskódú Python programnyelvben történt.

Authors: Telesh А. А. , Morozova Т. G.
Published: June 2023

Objective: to evaluate the potentials of contrast-free renal arterial spin labeling (ASL) perfusion during magnetic resonance imaging (MRI) for the diagnosis and dynamic follow-up of renal lesions in patients with diffuse liver diseases (DLD). Material and methods. The prospective study enrolled 82 patients with various DLD: alcoholic, viral, druginduced, autoimmune and mixed etiology. Ultrasound examination with Doppler abdominal and renal ultrasonography was conducted using Apogee 5300 (SIUI, China); abdominal MRI with contrast-free renal ASL-perfusion was performed using Vantage Titan 1.5 T (Toshiba, Japan). The parameters of renal perfusion (renal blood flow, RBF) were measured when the patients were admitted to the hospital, then during dynamic follow-up for 18 months. Results. Mathematical processing of results revealed normal RBF values (≥ 450 ml/100 g/min) and values associated with hepatorenal syndrome (HRS) (≤ 449 ml/100 g/min). High correlation between renal ASL-perfusion indicators and results of Doppler renal vessels ultrasonography was detected (r = 0,856). The diagnostic effectiveness parameters of contrast-free renal ASL-perfusion were: sensitivity 0.83, specificity 0.92, diagnostic accuracy 0.87. We created the algorithm of DLD patients examination for early HRS diagnosis and follow-up. Conclusion. Contrast-free renal ASL-perfusion is an informative method for predicting, diagnosis and dynamic follow-up of renal lesions in patients with various DLD.

Published: June 2023

Background. Self-expandable metal stents (SEMS) are widely used in gastrointestinal (GI) tract obstructive lesions. Planning and stent placement control can be performed with using roentgenological, endoscopic or combined method. The choice of the method depends on doctor’s preferences and clinic’s traditions, but endoscopic one is used more often. Comparison of the above methods efficacy in a single-institution material was not found in the literature. Objective: to compare clinical and roentgenological results of GI stenting depending on the method used. Material and methods. In 2016–2021, 267 cases of GI stenting were performed in Botkin Municipal Clinical Hospital. In 70 (26%) of them an endoscopic method was used, in 97 (36%) – a roentgenological one, and in 100 (37%) – a combined one. All patients underwent X-ray control postop. Results were analyzed statistically. Results. The implementation of X-ray diagnostics solo or in combination with endoscopy in GI SEMS planning and placement provided better results in comparison with endoscopic method only. Total SEMS expansion was achieved in 99% of cases versus 79% after only endoscopic procedures, correct stent placement – in 98% and 75%, respectively, evacuation was restored in 98% and 70%, respectively. All differences were statistically significant (p < 0.001). It is evident that X-ray methods are not useful for preliminary marking in decompensated patients with GI stenosis. But after elimination of such cases from analysis, the difference between the groups remained statistically significant (p < 0.05). Conclusion. The data obtained substitute expediency of X-ray method solo or with endoscopic one. Significant improvement of the results can be referred to more exact preoperative selection of SEMS type and size with X-ray method.
“Superscan” Scintigraphic Version for Prostate Cancer
Authors: Mironov S. P. , Sergienko V. B.
Published: June 2023

A rare scintigraphic phenomenon of “superscan” is considered – an abnormally high diffuse accumulation of osteotropic radiopharmaceutical by all skeletal parts in combination with the absence of kidney and tissue background imaging. This feature reflects a generalized bone system lesion of metastatic, metabolic or hematological nature. We present a clinical observation and retrospective assessment of scintigraphic data obtained during controlling androgen deprivation therapy in a patient with prostate cancer. Based on the analysis of “superscan” signs, including 99mТс-pyrophosphate hyperfixation by skull bones, as well as concomitant levels of prostatic specific antigen and parathyroid hormone (PTH), it was suggested that the identified scintigraphic phenomenon had metabolic nature, and its occurrence was possibly due to ectopic production of both PTH and parathyroid hormone-related protein, playing a well-known role in prostate cancer genesis.

Published: June 2023

Prostate cancer (PСa) is one of the leading causes of cancer morbidity in men. The incidence of localized PCa is higher in high-income countries. There are different types of treatment for localized PCa: from active surveillance to focal therapy or radical treatment. Both patients and urologists are interested in minimizing side effects of treatment, so focal therapy is an alternative option. Magnetic resonance imaging is one of the leading tools either for primary diagnosis or for following evaluation of treatment efficacy, including focal therapy. Therefore, we summarized literature data published on this topic.
How to Use Transformers for Transfer Learning?
Authors: Ebrahimzadeh Maryam , Asadi Hamidreza
Published: June 2023

Transformers are increasing replacing older generation of deep neural networks due to their success in a wide range of application. The dominant approach of using transformers is to pre-train them on a large training dataset and then fine-tune them on a downstream task. However, as transformers becoming larger, the fine-tuning approach is become an infeasible approach for transfer learning. In this short survey, we list a few recent methods that makes using transformers based on transfer learning more efficient.
Predicting the Effect of Surface Waviness on Fatigue Life of a Wire + Arc Additive Manufactured Ti-6Al-4V Alloy
Authors: Shamir Muhammad , Zhang Xiang , Syed Abdul Khadar , Sadler Wayne
Published: June 2023

This paper reports the effect of as-deposited surface condition on the fatigue strength in an additive manufactured titanium alloy Ti-6Al-4V (WAAM Ti64). First, local stress concentration caused by the surface waviness was quantified by a metrology technique followed by numerical modelling. Fatigue tests were conducted under bending load with the as-deposited surface being under tensile cyclic stress. The applicability of two predictive methods was studied and compared with the fatigue test results. The traditional notch stress method overestimated the fatigue strength by a factor of 1.5 at a given life; the poor agreement with the test is attributed to the crack propagation from the waviness being dominant in the bending test, i.e., the crack initiation stage was short, hence the local stress method is unsuitable. The fracture mechanics approach has delivered good predictions at every applied stress levels. The method treats a waviness trough as an initial crack. This approach is suitable for predicting the fatigue life in materials built by wire based directed energy deposition processes.

Published: June 2023

Distributed electric propulsion technology has great potential and advantage in the development of drones. In this paper, to study the slipstream effect of distributed propeller, the actuator disk method was used to verify a single propeller, and the calculated thrust was in good agreement with the test results. Then, based on the actuator disk method, the influence of different installation positions on the slipstream effect was studied, and the distributed propeller layout was optimized by genetic algorithm. The analysis results showed that lift of the wing will be larger when the propellers are higher than the wing. When the relative height between the propeller and the wing is zero, the drag is the lowest. The influence of disk diameter on the slipstream is that the larger the diameter is, the higher the lift force and the drag force are. The slipstream effect of the optimized propeller distribution improves the lift-drag ratio of the wing, by 108.5% in the initial lift-drag ratio.
Characterization of Chitin Synthase B Gene (HvChsb) and the Effects on Feeding Behavior in Heortia vitessoides Moore
Authors: Ling Chen Qing , Xu Sun Ming , Yang Wang Han , Han Liang Xiao , Liang Yin Ming , Tong Lin
Published: June 2023

The chitin synthase B gene is a key enzyme in the chitin synthesis of insect peritrophic matrix (PM), affecting insects' feeding behavior. The chitin synthase B gene has been cloned from the transcription library of Heortia vitessoides Moore. RT-qPCR showed that HvChsb was highly expressed in the larval stage of H. vitessoides, especially on the first day of the prepupal stage, and in the midgut of larvae and the abdomen of adults. After starvation treatment, HvChsb was found to be significantly inhibited with time. After 48 h of starvation, the feeding experiment showed that HvChsb increased with the prolongation of the refeeding time. The experimental data showed that feeding affected the expression of HvChsb. HvChsb was effectively silenced by RNA interference, so its function was lost, significantly decreasing the survival rate of H. vitessoides. The survival rate from larval-to-pupal stages was only 43.33%, accompanied by abnormal phenotypes. It can be seen that HvChsb plays a key role in the average growth and development of H. vitessoides.
The Impact of Mild Chronic Stress and Maternal Experience in the Fmr1 Mouse Model of Fragile X Syndrome
Authors: Subashi Enejda , Lemaire Valerie , Petroni Valeria , Pietropaolo Susanna
Published: June 2023

Fragile X Syndrome (FXS) is a pervasive developmental disorder and the most common monogenic cause of autism spectrum disorder (ASD). Female heterozygous (HET) carriers play a major role in the transmission of the pathology and present several FXS- and ASD-like behavioral alterations. Despite their clear genetic origins, FXS symptoms are known to be modulated by environmental factors, e.g., the exposure to chronic stress, especially during critical life periods, such as pregnancy. Pregnancy, together with pups’ care, constitutes maternal experience, i.e., another powerful environmental factor affecting several neurobehavioral functions in females. Here we investigated the impact of maternal experience on the long-term effects of stress in Fmr1-HET female mice. Our findings demonstrated that the behavioral abnormalities of HET females, i.e., hyperactivity and memory deficits, were unaffected by stress or maternal experience. In contrast, stress, independently of maternal experience, induced the appearance of cognitive deficits in WT mice. Maternal experience increased anxiety levels in all mice and enhanced their corticosterone levels, concomitantly promoting the effects of stress on social communication and adrenal glands. Our results advance our understanding of the environmental modulation of the behavioral alterations observed in FXS mice and highlight the long-term impact of maternal experience and its interactions with chronic stress.

Recent studies highlight the need to introduce objectives in Initial Teaching Education focused on the development of oral language competence (OLC). The main aim of the study is to examine activities to promote the development of OLC that are carried out in university classrooms and their evaluation, to analyze the relationship between students’ awareness of OLC work and class activities and to identify proposals to improve students’ OLC. Participants were 175 university teachers who teach on the bachelor’s degree in Initial Teacher Education (ITE) and the master’s degree in Secondary Education (MSE) at seven Catalan universities. The data collection instrument was an online questionnaire with 69 questions. The results indicate that 92.5% of participants work on OLC in their subjects, that 76.5% propose activities that are specifically linked to OLC and that 65.1% of participants evaluate OLC in their subject. A total of 39.4% of participants reported the need to increase discussions to generate processes of collaborative and interdisciplinary reflection between university teachers from different areas of knowledge, among others. We conclude that professional development processes need to be designed for ITE teachers to reflect on how they help students to develop OLC from a pragmatic perspective.
A Simplified Silty Sand Model

A unified critical state model has been developed for both clean sand and silty sand using the modified Cam-clay model (MCC). The main feature of the proposed model is a new critical state line equation in the e-ln(p) plane that is capable of handling both straight and curved test results. With this feature, the error in calculating plastic volumetric strain is eliminated in theory. Another crucial feature of the model is the transformed stress tensor based on the SMP (spatially mobilized plane) criterion, which takes into account the proper shear yield and failure of soil under three-dimensional stresses. Additionally, the proposed model applies the intergranular void ratio with the fines influence factor for silty sand. Only eight soil parameters are required for clean sand, and a total number of twelve soil parameters are needed for silty sand.
Flash Distillation Process for Stabilization of Anaerobic Digestate and Synthesis of Ammonium Bicarbonate

Published: June 2023

With the current increase in the demand from animal and agricultural products, management of agrowaste has become critical to avoid greenhouse gas emissions. The present article investigates the applicability of ammonium bicarbonate synthesis via flash distillation to valorize and stabilize several types of anaerobic digestate produced from individual fermentations of amino acids. Prior to the development of the model in Aspen Plus v12, the description of the system aqua-ammonia-carbon dioxide provided by the electrolyte non-random two-liquid property method was validated with empirical data available in the literature. The content of CO2 in the digestate was found to be responsible of the OH alkalinity (0.4 equivalents of acid/kg digestate), while the partial and total alkalinities (0.8 eq/kg digestate) were essentially derived from the content of NH3. The most suitable conditions for the flash distillation were 95 ⁰C and 1 bar with the condensation occurring at 25 ⁰C. However, in order to attain the precipitation of NH4HCO3 in the distillate, it was necessary to consider digestates with a moisture content of 50 wt.%, since the minimum levels of inorganic nitrogen and inorganic carbon were not attained otherwise. Even under these conditions, few amino acids (i.e. arginine, glycine, and histidine) were able to provide an anaerobic digestate, upon fermentation, that would be suitable for NH4HCO3 stabilization. Despite alanine digestate and glutamine digestate presented sufficient concentrations of inorganic nitrogen and inorganic carbon, the NH4HCO3-stabilization was not feasible due to the limited volatilization of NH3. The process of stabilization with a capacity of a tonne of digestate per hour was improved by adding hydrochloric acid or sodium hydroxide at rates 44 kg/h, leading to production of 34 kg NH4HCO3/h. The economic viability of this process needs to be investigated considering not only the market value of the isolated inorganic fertilizer but the carbon credits saved, resulting from handling a more stabilized organic manure. Furthermore, given the role of the volatile elements of the biogas as endogenous stripping agents, it is recommended to use a fresh and saturated digestate as feed for the flash distillation.

Worldwide, oral lesions and cancers are still being significant public health conditions. Thus, an introduction of new oral healthcare protocols is becoming essential. Oral diseases are related to many causative factors, manly dental plaque/biofilm due to poor hygiene. New anti-biofilm therapies are needed to develop. The strategies of anti-biofilm therapies should help to control biofilm formation and microbial attachment to dental surfaces. The present review aimed to provide a comprehensive over-view on evidence related to the potential utility of topical oxygen therapy (BlueM formula) as novel oral care therapies in clinical practice.

The determination and classification of seafloor sediment types are crucial for the exploitation of marine resources, construction of marine engineering, and maintenance of marine ecological en-vironments. Automatic classification of seafloor sediment based on acoustic telemetry data is an important method to quickly understand the type of a large range of sediment. Currently, most studies on sediment classification are based on multi-beam backscattering intensity data, which is a relatively single data type. Besides, the low-dimensional details of standard U-Net gradually weaken in the propagation process, limiting the accuracy of sediment classification. Therefore, this study proposes an automatic classification method of seafloor sediment types based on an im-proved U-Net and K-means clustering algorithm, using multi-beam water depth, sub-bottom profile, and sample test data in the Northern Slope of the South China Sea. Six sediment types, including gravelly muddy sand, sand, silty sand, less muddy silt, muddy silt, and silty mud, were identified in the study area. Additionally, the study area was divided into four sedimentary en-vironment zones, including the shelf sedimentary area, the upper shelf slope break sedimentary area, the lower shelf slope break mixed sedimentary area, and the slope deposition area, based on the results of sediment classification and geological background. The sedimentary environment zones were found to be distributed along the trend of the shelf slope break line. The results of this study not only provide an important supplement to the existing classification methods of seafloor sediments but also contribute to the understanding of the sedimentary environment and process of the Northern Slope of the South China Sea.

This study demonstrates the successful synthesis of Ni/Y2O3 nanocomposite particles through the application of ultrasound-assisted precipitation using the Ultrasonic Spray Pyrolysis technique. The particle size was predicted accurately using a modified equation, and they were collected in a water suspension with Polyvinylpyrrolidone (PVP) as the stabiliser. The presence of the Y2O3 core and Ni shell was confirmed with Transmission Electron Microscopy (TEM) and with electron diffraction. The TEM observations revealed the formation of round particles with an average diameter of 466 nm, while the lattice parameter on the Ni particle’s surface was measured to be 0.343 nm. The Ni/Y2O3 nanocomposite particle suspensions were lyophilized, to obtain a dried material that was suitable for embedding into a Polylactic acid (PLA) matrix. The resulting PLA/Ni/Y2O3 composite material was successfully extruded successfully, so that a 3D printed technology Fused Filament Fabrication could be used further for the production of tensile test tubes. The tensile tests showed that the addition of lyophilised Ni/Y2O3 into the PLA matrix decreased the tensile strength by 21.8 %, while the tensile modulus was not influenced. Dynamic Mechanical Analysis (DMA) showed that the addition of the Ni/Y2O3 particles increased the glass transition temperature by 5 °C, and increased the storage modulus in the glass transition range significantly. These findings demonstrate the potential for utilising Ni/Y2O3 nanocomposite particles in 3D printing applications, and warrant further exploration of their mechanical properties and potential applications in various fields.

This paper describes the influence of the regeneration treatments on 4-chloro-2-methyl-phenoxyacetic acid (MCPA)-loaded activated carbons (ACs) on adsorption-desorption cycles with two commercial ACs, Merck and Norit 1240 X ( Norit 1240 X was used in a granular and powder form). The ACs were saturated with MCPA and then submitted to four regeneration cycles, by washing with ethanol, NaOH solutions and washed with NaOH solutions followed by a thermal treatment. The ACs regenerated with ethanol showed a better performance concerning the successive adsorption-desorption cycles. On the first cycle, the MCPA desorbed, from washing with ethanol, from all ACs was higher than 99%. After a fourth adsorption-desorption cycle, washing regeneration combined with thermal treatment allowed excellent regeneration results. The amount of MCPA adsorbed on Norit 1240 X AC was higher than the amount adsorbed in the first cycle. MCPA adsorption kinetic data were analyzed by applying pseudo-first-order, pseudo-second-order, and Weber-Morris models. The pseudo-second-order fit better fit to the data and the Weber-Morris representation allows confirming that on Norit 1240 X, in a granular form, the pore diffusion was the limiting factor concerning the MCPA adsorption.
