Authors: Yessenbek Assylbek , Satayev Marat , Azimov Abdugani 
Published: February 2023

Abstract
The aim of the research is the production of activated carbon from the plum pit shells in a drum-type steam-gas furnace. To study the production of activated carbon, methods were used based on the study of individual patterns, analysis of the specific surface, determination of the porous structure, analysis of the structural-sorption and physicochemical characteristics of the pit shell. The novelty is research on determining the characteristics of activated carbon and the effect of thermal activation temperature in a flow of CO2 and H2O in a mass ratio of 20:80 on the pore volume. During activation at a process temperature of 780 °C, the surface was destroyed by powerful thermal activation, and as a result, micropores of 8–10 μm formed and a cell configuration arose. The adsorption kinetics showed that the maximum efficiency is achieved at a duration of 0.5 h for chloroform-extracted and 2 h for hexane-extracted oil products, as well as an adsorbent dose of 4 kg/m3. The results obtained in the research of the process of oily wastewater treatment showed that the effect of treatment with the activated plum pit shells (95.5%) is greater than the effect of treatment with coagulants and clays (88.5–71)%.

Published: February 2023

Abstract
Optimally designed water distribution networks (WDNs) make engineers’ tasks difficult due to various challenges like non-linearity between head-loss and flow, commercially available distinct diameters, combinatorial, nondeterministic polynomial-time hard problems and a large number of decision variables. This paper develops a new hybrid NSGA-II algorithm augmented with a random multi-point crossover operator and a local search denoted by RLNSGA-II to design the multiobjective WDN. The efficiency of the proposed algorithm (RLNSGA-II) is tested on three benchmark problems, namely New York, Hanoi and Balerma networks. The results obtained are compared with the best-known algorithms available in the literature. The results have shown that the proposed algorithm RLNSGA-II has found better converged and distributed solutions for all three representative benchmark problems considered in the literature consistently and evidently when compared with the best-known approximation of solutions published. Furthermore, as the complexity of the WDN increases, its advantages over other algorithms become more significant.

No presente trabalho, apresentamos uma pesquisa de revisão bibliográfica, em periódicos da área de Ensino, sobre a inserção das Questões Sociocientíficas na Educação (QSC) em Ciências. Para tanto, utilizamos como metodologia a pesquisa documental. Encontramos que a maior parte das pesquisas se concentra no Ensino Médio e na Formação de Professores; os componentes curriculares, que mais abordam as Questões Sociocientíficas, em sala de aula, são as Ciências Biológicas e a Física; enquanto os temas são “energia” e a ética do uso de animais em pesquisa científica. As pesquisas sobre levantamento de concepções relatam que os professores apresentam maior dificuldade em abordar as dimensões sociais e éticas com as temáticas QSC, pois ainda é muito tímido o estudo dessas questões nos cursos de licenciatura. Mesmo assim, as pesquisas mostram que os professores reconhecem nas QSC o potencial para a realizar uma alfabetização científica para a democracia.

Published: February 2023

Objective. The article proposes a method for finite element analysis of pipe-concrete columns in a physically nonlinear setting by reducing a three-dimensional problem to a twodimensional one based on the hypothesis of plane sections.Method.The equations of the theory of plasticity of concrete by G.A. Geniev are used. The technique was tested by comparing the solution with a calculation in a three-dimensional setting in the LIRA-SAPR software package, as well as with the experimental data of A.I. Sagadatov and calculation according to the current Russian design codes for steel-pipe concrete structures.Result. It has been established that the effective area of operation of columns with a circular cross section is small eccentricities of the longitudinal force.Conclusion. The proposed approach can be applied to the analysis of the stress-strain state and the bearing capacity of pipe-concrete columns of arbitrary section. There are no restrictions on the composition of concrete, and the shell material can be not only steel, but also fiberglass.

Background
The WEAICOR (Wearables to Investigate the Long Term Cardiovascular and Behavioral Impacts of COVID-19) study was a prospective observational study that used continuous monitoring to detect and analyze biometrics. Compliance to wearables was a major challenge when conducting the study and was crucial for the results.

Objective
The aim of this study was to evaluate patients’ compliance to wearable wristbands and determinants of compliance in a prospective COVID-19 cohort.

Methods
The Biostrap (Biostrap USA LLC) wearable device was used to monitor participants’ biometric data. Compliance was calculated by dividing the total number of days in which transmissions were sent by the total number of days spent in the WEAICOR study. Univariate correlation analyses were performed, with compliance and days spent in the study as dependent variables and age, BMI, sex, symptom severity, and the number of complications or comorbidities as independent variables. Multivariate linear regression was then performed, with days spent in the study as a dependent variable, to assess the power of different parameters in determining the number of days patients spent in the study.

Results
A total of 122 patients were included in this study. Patients were on average aged 41.32 years, and 46 (38%) were female. Age was found to correlate with compliance (r=0.23; P=.01). In addition, age (r=0.30; P=.001), BMI (r=0.19; P=.03), and the severity of symptoms (r=0.19; P=.03) were found to correlate with days spent in the WEAICOR study. Per our multivariate analysis, in which days spent in the study was a dependent variable, only increased age was a significant determinant of compliance with wearables (adjusted R2=0.1; β=1.6; P=.01).

Conclusions
Compliance is a major obstacle in remote monitoring studies, and the reasons for a lack of compliance are multifactorial. Patient factors such as age, in addition to environmental factors, can affect compliance to wearables.

ABSTRACTObjectivesTo assess the effect of piezocision on periodontal tissues and alveolar bone height and to detect lower second molar root resorption in piezocision-assisted mandibular second molar protraction compared to no-piezocision molar protraction.Materials and MethodsTwenty-one subjects (four males, 17 females, aged 22.43 ± 2.83 years) who presented with bilateral extraction of lower first molars were included. The patients were divided into two groups; Group 1: Piezocision-assisted molar protraction (right or left side of subjects) in which piezocision was performed immediately before lower second molar protraction and, Group 2: No-piezocision molar protraction in which lower second molar protraction was not surgically assisted. Plaque index (PI), gingival index (GI), periodontal pocket depth (PPD), width of keratinized gingiva (WKG), gingival recession (GR), lower second molar mesial root resorption, alveolar bone height, and mandibular bone height were recorded at T1 (immediately before molar protraction) and at T2 (after second molar space closure).ResultsIn the piezocision-assisted molar protraction group, significant changes were detected in the WKG (P &lt; .001), GR (P &lt; .05), and the mandibular bone height (P &lt; .001). Compared to the no-piezocision group, piezocision-assisted molar protraction resulted in an increased WKG (P &lt; .001) and less second molar mesial root resorption (P &lt; .01).ConclusionsPiezocision does not have any detrimental effect on the periodontium and produces less root resorption.
