Published: September 2022

Abstract
High temperature titanium alloys are considered as good candidate materials for many aerospace applications. In order to increase the usable temperatures and oxidation resistance of titanium alloys, plasma spraying thermal barrier coatings on the titanium alloys is considered as an effective method. The effect of plasma spraying process on microstructure and microhardness of the titanium alloy was investigated by scanning electron microscope, energy dispersion analytical X-ray spectroscopy and microhardness test. The results show that the microstructure of the titanium alloy inside the substrate keeps unchanged after plasma spraying, and no interaction and atomic diffusion happen evidently at the bond coat/substrate interface. However there exists a thin layer of plastic deformation zone in the substrate beneath the bond coat/substrate interface after plasma spraying. The residual stresses are induced inside the titanium alloy due to the thermal expansion mismatch and the temperature gradient inside the substrate during plasma spraying, and lead to generating microcracks in the surface beneath the bond coat/substrate interface and the increase of microhardness in the substrate.

Published: September 2022

Abstract
Many substrates do not sustain the conventional glazing process (i.e., vitreous glazing) due to the relatively high temperature required by this treatment (i.e., up to 1400 °C in some cases) to fuse glazes after their application on the surface to be covered. Thermal spraying could appear as a solution to circumvent this limitation and to avoid the thermal decomposition of the substrates. This contribution describes some structural attributes of glaze coatings manufactured by flame spraying. It also discusses the influence of the feedstock powder morphology and some of its physical properties on the coating characteristics.

Abstract
In order to address deficiencies in thermal spray coatings applied using air plasma spraying (APS) and high velocity oxygen fuel (HVOF), namely, adhesion, cohesion, porosity and line of sight limitations, novel hybrid coatings using post - thermal spray chemical vapor deposition via the pack cementation process were developed. Coatings based on tungsten carbide-cobalt chrome and chrome carbide-nickel chrome followed by boron or chrome diffusion were applied to multistage and single stage pump components for severe service applications in sand and alumina catalyst. Field testing established the effectiveness of using the dual coating approach.

Abstract
Hot corrosion tests have been conducted on Ni- and Cr-based laser coatings, a high-velocity oxy-fuel (HVOF) sprayed coating and various wrought alloys covered with a synthetic salt of Na2SO4-V2O5 and exposed at 650°C for 1000 h in air. Coating microstructures and reaction product layers were analyzed with scanning electron microscope (SEM) and energy dispersive spectrometer (EDS). The hot corrosion resistance of tested specimen was evaluated by measuring its mean thickness loss. Generally, wrought alloys, HVOF coating and Cr-based laser coatings suffered from selective corrosion beneath salt film, that is, distinct Cr-depleted layer was formed at alloy/salt interface. Cr-based laser coatings exhibited extended solid solubility and they transformed towards equilibrium condition. Cr-rich phases enriched further with Cr and they were prone to corrosion. Low diluted laser coatings and HVOF coating were more resistant to hot corrosion than commonly used industrial standard alloy, Nimonic 80A. Ni-based laser coating exhibited resistance equivalent to Cr-based coatings and superior to corresponding wrought alloy.

Published: September 2022

Abstract
This study examines the oxidation performance of two different iron aluminide coatings obtained by means of High Velocity Oxygen Fuel spraying starting from the same feedstock powder but using propylene and hydrogen as fuels. The isothermal oxidation tests were carried out at 900°C for 4, 36 and 72 hours. After detailed observation a more rapid oxide scale growth is obtained for that coating obtained under hydrogen conditions. It leads to the assertion that propylene-coatings would perform better under high temperature environments.

Published: September 2022

Abstract
The crushed and rounded ferroboron (FeB) powders of Fe-18.8B-0.2C-0.5Si-0.8Al (wt %) were deposited onto an aluminum substrate by thermal spraying methods to improve its tribological properties. Hexagonal boron nitride (h-BN) powders which have excellent lubricating properties like graphite were incorporated to the iron boride powders as solid lubricant by sintering process and high energy ball milling technique which allows homogeneous distribution of solid lubricants in a hard metallic matrix to obtain protective coatings with low friction coefficient. As-sprayed coatings are composed of mainly h-BN and FeB, iron matrix supersaturated with boron owing to the rapid solidification of molten droplets flattened on a substrate. The friction and wear behaviors of each coating were evaluated using ring-on-disk type wear tester under paraffin base oil condition in air atmosphere. Preliminary results revealed that iron boride powder with h-BN powder (5 wt.%) is an applicable method to produce a protective composite coating against friction and wear.

Background: Aureobasidium pullulans (black yeast) AFO-202 strain-produced beta glucan, Nichi Glucan, has been shown to improve the behavior and sleep pattern along with an increase in α-synuclein and melatonin in children with autism spectrum disorder (ASD). Objective: In this randomized pilot clinical study, we have evaluated the gut microbiota of subjects with ASD after consumption of Nichi Glucan. Methods: Eighteen subjects with ASD were randomly allocated: six subjects in the control group (Group 1): conventional treatment comprising remedial behavioral therapies and L-carnosine 500 mg per day, and 12 subjects (Group 2) underwent supplementation with Nichi Glucan 0.5 g twice daily along with the conventional treatment for 90 days. Results: Whole genome metagenome (WGM) sequencing of the stool samples at baseline and after intervention showed that among genera of relevance, the abundance of Enterobacteriaceae was decreased almost to zero in Group 2 after intervention, whereas it increased from 0.36% to 0.85% in Group 1. The abundance of Bacteroides increased in Group 1, whereas it decreased in Group 2. The abundance of Prevotella increased while the abundance of Lactobacillus decreased in both Group 1 and Group 2. Among species, a decrease was seen in Escherichia coli, Akkermansia muciniphila CAG:154, Blautia spp., Coprobacillus sp., and Clostridium bolteae CAG:59, with an increase of Faecalibacterium prausnitzii and Prevotella copri, which are both beneficial. Conclusion: AFO-202 beta 1,3–1,6 glucan, in addition to balancing the gut microbiome in children with ASD and its role in effective control of curli-producing Enterobacteriaceae that leads to α-synuclein misfolding and accumulation, may have a prophylactic role in Parkinson’s and Alzheimer’s diseases as well.

Published: September 2022

Taxes are an important source of revenue for the state; in order to maximize tax revenues, the government expects the community to participate in fulfilling their tax obligations based on tax provisions. According to data from the Ministry of Finance, the number of taxpayers in Indonesia increased from year to year, reaching 46.38 million in 2020. This figure increased from the previous year, with 42.51 million taxpayers in 2019. In 2017, and 2018, the number of taxpayers was 36.51 million and 39.15 million. In this case, tax revenues should increase rather than decrease, because the number of taxpayers increases year after year, but tax revenue realization falls short of the predetermined target. an imbalance in the achievement of predetermined tax revenue targets with the number of registered taxpayers, which continues to grow year after year. The purpose of this study is to analyze and investigate the impact of taxpayer awareness, taxpayer compliance, and tax collection with forced letters on tax receipts at Serpong Primary Tax Service Office. This is a quantitative study that employs primary data. Individual taxpayers (WPOP) registered at Serpong Primary Tax Service Office comprise the population of this study. A total of 400 respondents were sampled using a non-probability sampling technique. Data collection methods utilizing a questionnaire This study was carried out between August and November of 2021. Multiple linear regression analysis was used in this study as the regression model. The Statistical program version 25 was used to process the data. According to the findings of this study, Taxpayer Awareness, Taxpayer Compliance, and Tax Collection with Forced Letters all have a simultaneous and partial effect on Tax Revenue.

Undernutrition in children is an important problem of health care due to negative impact on the development of an organism and increase of global morbidity and mortality..Objective. To assess the clinical manifestations and food intake of children with undernutrition.Patients and methods. Four hundred and thirty-one children with undernutrition aged 1 month to 17 years and 11 months (the median of age is 7 [2.5; 13] years), boys – 238 (55.2 %), girls – 193 (44.8 %), were examined. All children underwent anthropometry using Z-Score values by WHO criteria (WHO Anthro and Anthro plus programs). Specialized centile tables were used with subsequent conversion of the obtained indicators into sigma deviations Z-Score in children with genetic syndromes. Undernutrition was registered in children with body mass index (BMI) by age Z-Score ≤ –1, the stunting was diagnosed with growth by age Z-Score ≤-2. Assessment of food intake at home was underwent in 199 children by recording and accounting for weighted food.Results. Mild undernutrition was diagnosed in 175 (40.6 %) children, moderate – in 127 (29.5 %), severe – in 129 (29.9 %) children. Severe undernutrition (43.2 % and 38.9 %) was most often registered in the age groups of 11–14 years and 15–17 years. The stunting was observed in 116 (26.9 %) children. The onset of malnutrition was revealed in three-quarters of children before the age of 1 year. The analysis of food intake revealed hypocaloric diet in 153 (76.9 %) patients, normocaloric diet in 32 (16.1 %) and hypercaloric diet in 14 (7 %) patients. Deficiency of protein, fat and carbohydrate intake was registered in 38.7, 72.4, 78.4 % cases, respectively, by assessment of macronutrient composition of the diet in children with undernutrition.Conclusion. Most children had mild undernutrition. Severe undernutrition was revealed significantly more often in patients of older age groups. Сhildren with undernutrition need early correction of the diet and appointment of nutritional support due to decrease in the energy intake in 76.9 % of children and the imbalance in macronutrients

In the dystrophic form of CEB (DEB), malnutrition is more often observed with prominent deficiency of micro- and macroelements, especially calcium and vitamin D, that can lead to rickets and osteoporosis with fractures.Aim of the study. To study the features of mineral and bone metabolism in patients with DHE and evaluate the effectiveness of prescribing different doses of vitamin D.Methods and mаterials. The study group included 71 children with DEB (girls 55 %, boys 45 %), the median age was 8.5 years [3.67; 11.92] and 5.75 years [3.13; 10.46], respectively. All patients underwent a complex laboratory and instrumental examination before and after 6 months of Cholecalciferol therapy.Results. We found a high rate of vitamin D insufficiency (22.5 %) and deficiency (40 %), hypocalcemia of total calcium (40 %), a decrease in bone mineral density (BMD) down to osteopenia (33.8 %) and osteoporosis (19.7 %). Osteocalcin (OC) and C-terminal telopeptide of type I collagen (CTx-1) levels in the group of patients with hypocalcemia were significantly lower than in the subgroup with normal levels of calcium (p=0.001 for OC, p=0.015 for CTx-1). Wasting of higher degree was noted in the group with hypocalcemia (p=0.001). 53.6 % of patients took Cholecalciferol irregularly (IU 1100 IU [700; 1500]), 35.2 % of patients constantly took the medicine (IU 2000 IU [1000; 3000]) (p = 0.021). After 6 months, normal levels of 25(OH)D were noted in 62 % of children; the levels of P1NP (p<0.001), phosphorus (p=0.012) decreased, and BMD improved (p=0.024). According to the plan developed in our study, with level of 25(OH)D ≤ 30 ng/ml, children aged 1–7 years old should be given at least 1500 IU; at 7–12 years – 2500 IU; at 12–18 years – 3000 IU.Conclusion. To achieve optimal levels of vitamin D, calcium, and bone turnover markers in children with DEB, it is necessary to use a personalized approach for colecalciferol prescription.

Aim of the study. To investigate the frequency and clinical significance of detecting increased serum levels of IgE to food proteins, eosinophils (EOs) and mast cells (MCs) in colon biopsies in children with inflammatory bowel disease (IBD) in remission or with a low degree of activity.Methods and materials. 165 children with IBD and 81 children of the control group were examined. The level of serum sIgE to cow’s milk and wheat was determined. To detect cow’s milk protein allergy (CMPA), we used the questionnaire «Food Allergy» previously developed by us and validated on a group of patients with IBD. We performed the microscopy of histological preparations of the intestinal mucosa with counting of EOs and MCs.Results. The frequency increased sIgE levels to CMP in children with CD was higher than in children with UC, but there were no differences in the frequency of sensitization in the comparison group of children without allergies and IBD. An increased number of MCs was present in 37.0 % of IBD patients: 37.9 % of children with CD and 35.3 % of children with UC. Intestinal eosinophilia was observed in 15.2 % of children with IBD: 10.3 % with CD and 23.5 % with UC. A correlation was found between the average number of MCs in the biopsy specimen and the questionnaire score sums, in UC, as well as between the average number of EOs in the biopsy specimen and the questionnaire score sums and between the average number of MCs in the biopsy and the questionnaire score sums. In patients with CD, there is a correlation between the average number of MCs in the biopsy and the questionnaire score sums. Differences at the trend level were found between the average values of MCs in intestinal biopsy specimens in children with IBD with and without FA.Conclusion. The found correlation between the average number of MCs and EOs in the biopsy and the the questionnaire score sums shows that increased levels of intestinal MCs and EOs can be considered a diagnostic criterion for FA in patients with IBD with the presence of clinical data.
