Authors: Filyashkin Мykola 
Published: May 2023

The guidance system of a fire-extinguishing bomb in the form of a hinged guidance kit is considered, which turns the bomb into a simple and fairly cheap fire-extinguishing device of the "throw and forget" type, optimized for mass production and use. In order to increase the accuracy of dropping a fire-extinguishing bomb, it is proposed to install a cheap high-precision and compact GPS navigation satellite system and a strapdown inertial system on an ordinary fire-extinguishing bomb. The algorithm of complex information processing of their systems, built on the basis of the improved method of the mutual compensation, in which for improve the quality of the error estimation procedure, the sluggishness of second-order Butterworth filters is compensated is proposed. The guidance system controls the trajectory of the fire-extinguishing bomb as a means of "first strike" and this increases the efficiency of further use of traditional flood systems by 50...70 times.

Promoting Urban Health through the Green Building Movement in Vietnam: A Transdisciplinary Perspective
Authors: Nguyen Thuy Thi Thu , Waibel Michael 
Published: May 2023

The health of urban citizens is defined by how their living environments are planned, built, and operated. These complex relations between health and the characteristics of built environments require system-orientated thinking and transdisciplinary interventions, yet have mainly been addressed using conventionally narrow sector-based approaches. This paper investigates the opportunities and challenges of the Vietnamese Green Building Movement (GBM) based on a transdisciplinary approach, with attention to additional health benefits of green buildings that are currently under-researched, while highlighting building users’ perspectives. Focusing on the perspectives of high-rise building residents, the paper examines transdisciplinary insights collected from six thematic webinars, expert interviews, and, in particular, from a household survey conducted in Ho Chi Minh City, Vietnam.
Among other findings on opportunities and challenges for the Vietnamese GBM, the paper points out a challenging mismatch between the high importance homebuyers place on green building health benefits, and the focus of GBM stakeholders on GB energy-saving benefits- which are not necessarily homebuyers’ most pressing concerns. With this evidence-based inquiry, the paper concludes that improved health and well-being should be considered co-benefits of green buildings, along with energy efficiency. Importantly, this paper also brings attention to the necessity of a systemic and transdisciplinary approach in both academic and practical efforts toward the implementation of SDG3- to “ensure healthy lives and promote wellbeing for all ages”- and SDG 11- “to make cities and human settlements inclusive, safe, resilient and sustainable”.

Abstract
Exposure to metals can disrupt the human immune system. However, few studies have explored the potential effects of multiple metals co-exposure on immune function related to inflammation markers in human. This study examined the associations between metals exposure and inflammatory markers.The Data were gathered from the 2013–2016 period of National Health and Nutrition Examination Survey (NHANES). Inflammatory markers included platelet count (PLT), platelet-to-lymphocyte ratio (PLR), mean platelet volume (MPV), the ratios of MPV to PLT (MPVP), white blood cell (WBC), and neutrophil-to-lymphocyte ratio (NLR). Associations between 13 urinary metals and inflammatory markers were estimated. Generalized linear model showed urinary barium, cadmium, lead, thallium and cobalt concentrations were associated with MPV, PLR, and NLR. In quantile g-computation, urinary metal mixture was negatively associated with MPV, but positively associated with PLR and NLR. Overall, our study demonstrated that metal mixture was associated with inflammation markers including MPV, PLR, and NLR, which enhancing the inflammatory response.

Abstract
In this paper, a new copper complex of Cu(dapymt)·4H2O (CuDpy) with strong and stable orange fluorescence was synthesized by using 4,6-diamino-2-mercaptopyrimidine (dapymt) as the ligand. Based on the excellent luminescent property of CuDpy, a bifunctional ratiometric fluorescent probe of CuDpy-CDs was constructed adopting CuDpy as the response fluorescent signal and blue-emitting carbon quantum dots (CDs) as the reference fluorescent signal. In the selective identification of anion and cation, CuDpy-CDs probe can specifically identify Ag+ and S2-. The detection limits for Ag+ and S2- were 1.88 μM and 0.16 μM, respectively, while the detection linear range of CuDpy-CDs for ions were 0-400 μM and 0-35 μM, respectively. In addition, a CuDpy-CDs portable sensing gel was fabricated which can monitor the approximate concentration of Ag+ and S2- in wastewater by the color change of fluorescence.

Abstract
OBJECTIVE To investigate the value of CT radiomics in predicting epidermal growth factor mutation status in lung cancer.MATERIALS AND METHODS Data from Hospital 1 (n = 119) and Hospital 2 (n = 49) were used as the internal dataset and data from the Cancer Genome Project (TCGA) database (n = 14) were used as the external validation set. After image segmentation, feature extraction and feature downscaling screening, radiomics models were constructed. Clinical features and conventional imaging markers used to predict EGFR mutation status were screened by univariate and multivariate logistic regression to construct the clinical model. Combining radiomic features and clinical features by multivariate logistic regression to construct a combined model. The predictive performance of each model was assessed using operator operating characteristic (ROC) curves, and the clinical utility of each model was assessed using clinical decision curves.RESULTS Three models based on CT flat-scan were developed: a radiomics model, a clinical model and a combined model. The area under the curve (AUC) for the training set radiomics, clinical and combination models were 0.0.87 (0. 79-0.95), 0.68 (0.57–0.80) and 0.87 (0.80–0.95) respectively; the AUC values for the validation set radiomics, clinical and combination models were 0.73 (0.55–0.90), 0.71 (0.54–0.88) and 0.73 (0.56–0.90) respectively.The clinical decision curves indicate that the combined model has better clinical decision benefits than the radiomics model alone and the clinical model alone.CONCLUSION The combined model combining radiomic features and clinical features further improved the predictive efficacy compared to the radiomic model alone and the clinical model alone.

Published: May 2023

Abstract
Background Respectful maternity care (RMC) remains a key challenge in Afghanistan, despite progress on improving maternal and newborn health during 2001–2021. A qualitative study was conducted in 2018 to provide evidence on the situation of RMC in health facilities in Afghanistan. The results are useful to inform strategies to provide RMC in Afghanistan in spite of the humanitarian crisis due to Taliban’s takeover in 2021.Methods Focus group discussions were conducted with women (4 groups, 43 women) who had used health facilities for giving birth and with providers (4 groups, 21 providers) who worked in these health facilities. Twenty key informant interviews were conducted with health managers and health policy makers. Motivators for, deterrents from using, awareness about and experiences of maternity care in health facilities were explored.Results Women gave birth in facilities for availability of maternity care and skilled providers, while various verbal and physical forms of mistreatment were identified as deterrents from facility use by women, providers and key informants. Low awareness, lack of resources and excessive workload were identified among the reasons for violation of RMC.Conclusion Violation of RMC is unacceptable. Awareness of women and providers about the rights of women to respectful maternity care, training of providers on the subject, monitoring of care to prevent mistreatment, and conditioning any future technical and financial assistance to commitments to RMC is recommended.

Published: May 2023

Abstract
Purpose
To develop and validate an optimal radiomics model for preoperatively predicting microsatellite instability (MSI) in patients with rectal cancer (RC) based on multiparametric magnetic resonance imaging.
Methods
The retrospective study included 308 RC patients who did not receive preoperative antitumor therapy, among whom 51 had MSI. Radiomics features were extracted and dimensionally reduced from T2-weighted imaging (T2WI), T1-weighted imaging (T1WI), diffusion-weighted imaging (DWI) and T1-weighted contrast enhanced (T1CE) images for each patient, and the features of each sequence were combined. Multifactor logistic regression was used to screen the optimal feature set for each combination. Different machine learning methods were applied to construct predictive MSI status models. Relative standard deviation values were determined to evaluate model performance and select the optimal model. Receiver operating characteristic (ROC) curve, calibration curve, and decision curve analyses were performed to evaluate model performance.
Results
The model constructed using the k-nearest neighbor (KNN) method combined with T2WI and T1CE images performed best. The area under the curve values for prediction of MSI with this model were 0.849 (0.804–0.887), with a sensitivity of 0.784 and specificity of 0.805. The Delong test showed no significant difference in diagnostic efficacy between the KNN-derived model and the traditional logistic regression model constructed using T1WI + DWI + T1CE and T2WI + T1WI + DWI + T1CE data (P > 0.05) and the diagnostic efficiency of the KNN-derived model was slightly better than that of the traditional model. From ROC curve analysis, the KNN-derived model significantly distinguished patients at low- and high-risk of MSI with the optimal threshold of 0.2, supporting the clinical applicability of the model.
Conclusions
The model constructed using the KNN method can be applied to noninvasively predict MSI status in RC patients before surgery based on radiomics features from T2WI and T1CE images. Thus, this method may provide a convenient and practical tool for formulating treatment strategies and optimizing individual clinical decision-making for patients with RC.
Agricultural lime reaction and retention in a diversity of soils under continuous centrifugation

Published: May 2023

Abstract
Agricultural lime is an important natural resource for changing soil pH values. Annual lime applications in the UK have fallen for decades. Estimating soil factors that contribute to the retention and losses of lime would be useful for farmers making resource decisions. The aim of this research was to analyse the soil factors contributing to leaching loss and retention of agricultural lime in Scottish grassland soils. This research also tested the applicability of a large centrifuge method for measuring leached solutions from soil, suggested as an alternative to leaching columns. The soils studied in this research were highly variable in their response to lime. Measures of soil exchange capacity (cation exchange capacity, lime buffering capacity and organic matter) and clay content were highly associated factors to calcium loss and retention within a soil. Suggestions to farmers include consideration of soil clay content, organic matter content (as expressed through C) and cation exchange capacity as factors in lime decision making. Higher exchange capacity soils lost more calcium, likely due to the greater liming requirement of these soils and potential increased excess calcium applied. It is suggested that methods for improving calcium exchange and soil uptake be explored for improving lime retention after liming events.

Abstract
Background
Acute gout is a form of inflammatory arthritis characterized by a sudden, acute onset of pain, swelling, warmth, erythema, and decreased range of motion in the affected joint. Although numerous studies have focused on the phenotypes of immune cells, the complete immunophenotypic atlas of patients with acute gout remains unelucidated. Hence, we aimed to comprehensively examine the general immunologic condition of patients with acute gout and compare it with that of healthy donors (HD).
Methods
We collected peripheral blood mononuclear cells (PBMCs) from patients with acute gout (n = 31) and healthy donors (HDs) (n = 16) to investigate the immunophenotype of acute gout. Furthermore, the components and kinetics of the immune response were examined in these patients.
Results
By demonstrating the frequency and phenotype of immune cells, such as neutrophils, monocytes, and natural killer (NK) cells, we discovered that patients with acute gout had significantly higher neutrophil-to-lymphocyte ratio (NLR) and neutrophil-to-T-cell ratio (NTR) than that in HDs. We also observed a significant association between NTR and C-reactive protein (CRP) levels. Furthermore, NK cell cytotoxicity was reduced, and heterogeneous T cell activation and plasmablasts (PBs) frequencies were increased in patients with acute gout.
Conclusion
Our findings demonstrate substantial perturbations in leukocytes, including T cells, B cells, NK cells, and monocytes, in patients with acute gout. Thus, NTR may serve as a biomarker of acute gout. These findings may facilitate the easier implementation of novel preventive and therapeutic strategies against acute gouty arthritis.
