INVESTIGATION OF THE GAS MIXTURE ADSORPTION PROCESS IN A
FIXED LAYER OF THE NaX ADSORBENT
Authors: Bayramova Aygun
Published: April 2022

The paper describes a 4-adsorbent installation for cleaning gas mixtures from H2S, CO2
and NO2 with zeolite. The lower and upper limits of the condensate level in the
separator were controlled by electric contact pressure gauges, and the pressure was
recorded on the operator panel. The number of adsorbers is 4, the height of the fixed
zeolite layer is 3.6 m. Long-term operation of the adsorption unit under real operating
conditions has shown that the temperature of zeolite regeneration largely depends on
the quality of the gas entering the adsorption unit. As can be seen, the desorption of
carbon dioxide is completed at the beginning, then hydrogen sulfide, and at the end -
moisture vapor, and the time for complete desorption of all adsorbed components is
limited by internal diffusion inhibition of the sorbed components. The greatest
desorption time, as expected, is due to moisture vapors. It has been experimentally
established that when heated with hot gas at the maximum permissible speed, the time
for complete desorption of moisture is 150-160 minutes. For practical calculations, the
time required for complete dehydration of the zeolite is taken at least 3 hours, which is
confirmed experimentally.
Keywords: adsorption, synthetic zeolite NaX, fixed adsorbent layer, gas mixture,
desorbed substances.

Local piezoelectric properties of perforated ferroelectric barium–strontium titanate films
Authors: Sherstyuk N. E.
Published: April 2022

Objectives. Focused ion beam etching remains one of the most common methods for fabricating 2D photonic crystals and structures based on functional materials. This technique is quite well developed for semiconductors. But at the same time, the change in the properties of ferroelectric materials under the action of a focused ion beam, including parameters of distribution and switching of the polarization state under the action of an electric field, remains poorly studied. The purpose of this work is to determine the local piezoelectric parameters in perforated ferroelectric films of barium strontium titanate (Ba0.8Sr0.2TiO3) with ordered vertical air channels fabricated by focused ion beam etching.Methods. Experimental studies were conducted using piezoresponse force microscopy under applied electric field in planar geometry.Results. It is shown that the perforation of a ferroelectric film leads not only to the formation of significant inhomogeneities in the piezoelectric response distribution in the structure, but also to the noticeable increase in the magnitude of both the vertical and lateral components of the piezoresponse near the perforation holes. The calculation results showed that the greatest enhancement is observed for the lateral component of the piezoresponse: from 5 pm/V for a nonperforated film to 65 pm/V in the perforated area.Conclusions. The most probable mechanism for such a change in properties is the influence of a disturbed layer that occurs at the boundary and the inner surface of vertical air channels. The properties of this layer are due to two factors: amorphization of the structure as a result of the focused ion beam etching and the appearance of pinned domain states near the hole, leading to the formation of the complex piezoresponse distribution both at the hole boundary and in the gap between the perforations. The information obtained is important for understanding the peculiarities of the formation of local piezoelectric and ferroelectric responses in photonic crystals fabricated by focused ion beam etching, as well as for finding ways to control their state when an external electric field is applied.

Relevance. When using protease in the feeding of broiler chickens, the question arises about its effect on other enzyme additives. The solution to this problem can be the use of multienzyme compositions.Methods. The titrometric method for determining nitrogen (according to Kjeldahl), followed by conversion to protein, allows us to evaluate the efficiency of the enzyme complex, taking into account changes in the composition of the diet in different phases of feedingResults. It was found that the use of the multienzyme feed additive “Natuzyme” allows to obtain a high digestibility of feed protein, especially at the final fattening – 84.1%, with the introduction of 5% sunflower meal into the diet.
The changes of economically valuable signs got under the influence of gamma-ryes
Authors: Rzayeva I. I.
Published: April 2022

Relevance. The plants treated and modified under the influence of a physical mutagen of the Co60 isotope at doses of 500, 1000, 5000, 10000, 20000 and 30000 r were grouped into types. Changes in such economically valuable features as yield per one bush, fiber yield, weight of raw cotton in one boll and fiber length under the influence of the Co60 isotope in experimental optionss were studied. With an increase in the dose of gamma rays, an increase in fiber yield was observed. In the AzNIHI-195 variety, when exposed to a lower dose of gamma rays (500 R) on seeds before sowing, the fiber yield was 35.9%, at a high dose (30,000 R) — 37.2%. Fiber yield varies depending not only on the variety, but also on the placement of the bolls on the bush. Forms with short and long fibers selected according to various options are of particular importance as a starting material and on their basis, in the next generation, it is possible to select forms with long fibers. The resulting economically valuable forms will be used as starting material in breeding work.Methods. The research studied the change in the mass of raw cotton of one boll under the influence of gamma rays on seeds. The results of the impact of gamma rays on the seeds of varieties AzNIKHI-104 and AzNIKHI-195 in M 1 shows a change in the mass of raw cotton in one boll. On this basis, sharp differences were obtained both in the effect of different doses of gamma rays among themselves, and in comparison with the control option. In the variety AzNIKHI-104 in M1, the obtained differences were at the ranges of 0.2–0.9 gr. At a high concentration of mutagens, a sharp change in the average weight of one boll was observed.Results. In both varieties, an increase in the dose of the mutagen leads to an increase in both the mass and the yield of raw cotton fiber, while the yield of raw cotton in one bush decreases. When exposed to high doses, low-yielding, semi-sterile and sterile plants are obtained, and the length of the fiber increases at low doses. A similar result is observed in both cotton varieties.

Published: April 2022

So far, fishermen are associated with the poor with low education. This is due to the livelihood of fishermen who depend on the sea, which is very dynamic and uncertain. However, during the last 20 years, there has been a change in the perspective and aspirations of fishermen’s families towards their children’s education. The factors of fishermen’s livelihood, which are increasingly difficult and increasing accessibility, are expected to change the perspective on education. This research aims to explore the factors that change the aspirations of fishermen’s families towards education, both formal and informal education in Purworejo Village - Demak. The qualitative research method with ten informants conducted in-depth interviews, three focused discussions, and field observations to understand the existing phenomena. Focused discussions were conducted online and offline due to the COVID-19 pandemic situation in the research area. Data collection was carried out in July-August 2020 and March 2021. The results showed that the fishermen had seen the importance of their children getting a higher education. The increasing aspirations of fishermen’s parents towards education cannot be separated from the Family Hope Program (Program Keluarga Harapan or PKH), which can at least increase the school participation level of fishermen’s children. Parents expect their children to have a wider choice of jobs than those who live by profession as a fisherman, namely employee of the last resort.
A Comparative Study on Mortar Removal Methods and their Influence on Recycled Aggregate Properties
Authors: Kim Jeonghyun , Jang Haneol
Published: April 2022

The adhered mortar attached to recycled aggregate (RA) is one of the main causes of weakening the mechanical properties and durability performance of recycled aggregate concrete (RAC). Therefore, in order to improve the performance of RA and RAC, several methods have been proposed to remove the adhered mortar in RA. However, knowing the adhered mortar content is as important as removing it. This is because concrete mix designs considering the amount of adhered mortar have been proposed and better strength, durability and environmental benefits of these mix designs were reported compared to conventional RAC mix design. Therefore, in this study, the adhered mortar was removed by using two methods of ‘acid treatment’ and ‘chemical and mechanical stress treatment’ for three types of RA, and the test results obtained from each method were comparatively analyzed. The results showed that the adhered mortar contents determined by the two methods were different for the same aggregate, and neither allowed the complete removal of the adhered mortar from RA. It also showed that the test environment of the chemical-mechanical stress method can be harsh enough to damage the original aggregate in RA, and that the acid treatment can cause corrosion of RA depending on the type of aggregate.
Pre-Hospital Early Warning Scores are Associated with Requirement for Medical Retrieval Services
Authors: Smith Jeremy , Andrew Emily , Smith Karen
Published: April 2022

Objective

Prehospital early warning scores (EWSs) can accurately identify patients at risk of clinical deterioration. We hypothesised that EWSs can identify patients during the prehospital phase who will subsequently require clinical escalation via medical retrieval.

Methods

A retrospective observational study of adult patients attended in 2018 by Ambulance Victoria in rural regions was conducted. We calculated EWSs using National Early Warning Score 2 (NEWS2) and Rapid Emergency Medicine Score (REMS) methods. Primary outcome was activation of Adult Retrieval Victoria (ARV) within 24h of ambulance attendance. We evaluated sensitivity and specificity for each score, and used multivariable logistic regression analysis to assess the independent association between EWSs and ARV activation.

Results

A total of 71,401 patients were included, of which 607 (0.9%) required ARV activation within 24 hours. Sensitivity and specificity of NEWS2 were 0.484 (95% CI 0.444-0.525) and 0.806 (95% CI 0.803-0.809) respectively, compared with 0.552 (95% CI 0.511-0.592) and 0.508 (95% CI 0.504-0.512) respectively for REMS. After adjustment for remoteness, distance to hospital, sex, age and hospital service level, a medium/high risk score according to the NEWS2 (OR 4.12; 95% CI 3.50-4.85, p < 0.001) and REMS (OR 2.92, 95% CI 2.26-3.77) was associated with ARV activation. Odds of ARV activation increased with remoteness and decreasing service level of the receiving hospital.

Conclusions

Prehospital NEWS2 and REMS were associated with medical retrieval within 24h of ambulance attendance. EWSs may allow early identification of ambulance patients requiring medical retrieval, thus facilitating earlier activation and reduced time to definitive care.

Abstract During the Covid 19 pandemic in Indonesia, it has weakened various sectors of life in society, including the economic sector. Various policy efforts have been carried out by the government to deal with the covid 19 virus outbreak, one of which is the government implementing PPKM level 4. People in the lower middle class such as street vendors really feel the impact that occurred because of this policy most of the street vendors experienced a drastic decrease in turnover due to the PPKM period with strict rules so that community activities were very limited and made traders hampered in the trading process. The formulation of the problem used in this study is to determine the impact caused during the Enforcement of Community Activity Restrictions (PPKM) level 4 in Sukoharjo. One of the objectives of this study was to determine the impact of level 4 Community Activity Restrictions (PPKM) on street vendors, especially in the Sukoharjo area. The method used in this study uses a case study approach with data collection sourced from primary data. The data obtained were Â analyzed qualitatively. Sources of data in this study are the results of questionnaires to the public and the results of interviews from Mr. Suraji as a basic necessities trader, Mrs. Wiji as a kebab seller, and Mr. Afthon as a Labmilk trader in Gentan. The results showed that PPKM level 4 had an impact including: (1) a very significant decrease in turnover; (2) consumers are starting to switch to online shopping instead of offline shopping: (3) unequal government assistance to merchants I.

One of the national goals of the State of Indonesia is to improve people's living standards, including in the health sector which is closely related to medicine. The management and distribution of drugs is strictly monitored by the government and can only be done at Pharmaceutical Service Facilities, one of which is a pharmacy. In The Minister of Health Regulation Number 14 of 2021 it is regulated that pharmacies can be operated by individual or non-individual business actors in the form of legal entities. This study wants to examine the implementation of The Minister of Health Regulation Number 14 of 2021 on the extension of pharmacy licenses. This study uses a legal research method with a statutory and conceptual approach. From the results of the study, it was found that the rules regarding the licensing of these pharmacies have been specifically regulated and the existing laws and regulations are coherent, but has not provided legal certainty for pharmacy business actors. The Minister of Health Regulation Number 14 of 2021 causes difficulties for business actors and the current OSS system is still unable to accommodate the needs of business actors.
Association of IL1B -511T>C, IL6 -634G>C, IL-6 -174G > C, miR -149 T>C AND miR-27aA>G gene polymorphisms with recurrent pregnancy loss risk in greek population

Introduction: Recurrent pregnancy loss (RPL) is defined as the spontaneous loss of two or more idiopathic consecutive clinical pregnancies prior to 22 completed weeks of gestation. Association of miRNA polymorphisms with RPL has been investigated as a genetic determinant for the risk of idiopathic RPL. Moreover, mutations in several interleukins’ genes have been also related to RPL. Material and Methods: The study was carried out between September 2019 and September 2021 in Alexandra Maternity Hospital. Two hundred women with at least two consecutive spontaneous abortions (RPL) and 200 women as a control group who have completed one pregnancy were included in this study. Blood samples were collected from which genomic DNA was extracted, and PCR was performed to identify the IL1B -511T>C, IL6 -634G>C, IL-6 -174G > C, miR -149 T>C AND miR-27aA>G genotypes. Results: Of the 5 genes tested, genotype and group correlation were found in IL-1b-511 and miR-27. In specific, in the IL-1b-511 gene, cases have a 77.2% statistically significantly higher relative probability of having the polymorphism (CC genotype) than the control group (OR = 1.772, p = 0.007). In addition, in the miR-27 gene, cases are 3.2 times statistically significantly more likely to have polymorphism (GG) compared to controls (OR = 3.283, p <0.001). Conclusions: A genetic panel related to recurrent abortions is proposed. Gynecologists and researchers may apply it to establish a personalized treatment in women with RPL. The establishment of genetic panels related to infertility issues leads to more efficient solutions for the achievement of a pregnancy.

Background: Preeclampsia (PE) is a multi-systemic progressive disorder that is unique to human pregnancy, occurring usually after 20 weeks of gestation. Useful biochemical markers to be utilized for early prediction of preeclampsia continue to elude us. The search for biomarkers is aimed identifying women at increased risk of developing PE, so that medical interventions may be instituted very early in pregnancy to ameliorate its occurrence and improve maternal and fetal outcome. Aim: This study aimed to determine the association between serum levels of Cystatin C and/or free β-subunit of hCG measured in early pregnancy and the development of pre-eclampsia and its severity. Methods: This was a prospective cohort study of 290 pregnant women recruited during routine antenatal care, at the gestational age of between 13 and 19 weeks. After obtaining an informed consent from each participant, a structured questionnaire was used to collection relevant information followed by the collection of 5 mL of venous blood sample. Serum cystatin C and free sub unit of β-hCG levels were determined by standard enzyme-linked immunosorbent assay (ELISA) method. All participants were followed up till delivery and those who developed preeclampsia was classified as mild and severe preeclampsia. Data were entered and analyzed using STATA version 16 statistical software. Hypothesis testing was done using chi-square test for categorical variables, and the independent-samples t-test and ANOVA for numerical variables. Results: We found significantly elevated serum levels of cystatin C and free subunit of β-hCG in women who developed preeclampsia, (p < 0.002 and 0.001) respectively. Conclusion: Our study has shown that in a healthy population of pregnant women that elevated serum levels of cystatin C and free beta hCG concentration measured in early second trimester were associated with an increased risk of developing preeclampsia and its severity. This suggests that the combination of these analytes may have a role as a marker of pre-eclampsia and its severity especially when used in combination.

A 7 km section of CRCP was constructed on the Ban-Etsu Expressway, which was opened in October 1990, in heavy snowy region of the Japan main island. Transverse cracks had opened wide and the crack spacing had become shorter just after 9 year service, resulting in punchout on the surface. The deteriorated part of the CRCP section had been repaired with the partial depth patching using SFRC and double layer asphalt overlay. However , the similar severe deterioration has appeared on the other parts of the section recently. Therefore, in 2018, comprehensive investigations including material tests, excavation of the slabs and joints, FWD tests and ground penetrator radar (GPR) survey were conducted to establish the rehabilitation strategy for the CRCP section. In the investigations, horizontal cracks were found at a depth of the reinforcement bar, which started from the transverse crack. Also, some extracted bars were severely corroded. The material tests revealed high chloride ion concentration in the upper part of the concrete slab. Based on those investigation results, it was assumed that the expansion of the corroded reinforcement bars initiated and developed the horizontal cracks at the position of reinforcement bars, which divided the CRC slab into two layers, resulting in severe punchout.

Around the world, urban development and densification leads to the Urban Heat Islands (UHI) effect, in which cities are warmer than adjoining rural areas. Cool pavements have been recommended as a mitigating strategy for the UHI effect. However, the spatial extent over which cool pavements need to be applied to achieve widespread mitigation has received little attention. A previously developed urban microclimatic model for the Power Ranch community in suburban Phoenix, Arizona, was used to investigate this question. The microclimatic model is used to investigate the effects of urban densification for the meteorological conditions at 5:00 PM on August 13, 2015. In the modeled scenario, the heights of the buildings were increased from 5 m to 10 m, a large, central park was redeveloped as a parking lot, and a reflective pavement was implemented in the parking lot. Both localized and downwind air temperature effects at 2m of this further densification were quantified in the modelling effort. For the lower building height, using typical concrete to redevelop the park as a parking lot increased the 2 m air temperature directly over and downstream by about 0.20℃. When a reflective concrete parking lot was used instead, the 2m air temperature decreased by 0.20℃ over and downstream. At 10 m building heights, the reflective parking lot decreased the 2 m air temperature by 0.20℃, however, its effect was more localized with less benefit for downstream areas. Thus, urban form with taller buildings affects the airflow, which requires a more distributed application of reflective surfaces to mitigate UHI.
