Abstract
With the increase of the turbine inlet temperature of high-efficiency gas turbines, developing the bond-coat with higher temperature oxidation resistance is also necessary. In the paper, CoCrNiAl0.6 middle entropy alloys with different content reactive elements Y were prepared, and the effects of Y content on the microstructure and oxidation behavior at 1200 ℃ were studied. All alloys consist of β phase and γ phase，but CoCrNiAl0.6Y (0.11) shows some sub-micron γ phase precipitates are within the β phase. The oxidation behavior at 1200 ℃ of CoCrNiAl0.6Yx (x=0.05, 0.08, 0.11) confirms that dense oxide scale can be formed at the alloy surface, the surface with aluminum oxide accompanied yttrium oxide makes better adhesion between the matrix and oxide scale. The CoCrNiAl0.6Y (0.11) alloy has the best oxidation resistance with lower oxidation rate of 5.704×10-12 g2/(cm4·s), which is also far better than the conventional NiCoCrAlY alloy with typical compositions.
Gender and household food security in Ghana: Assessing food security and dietary diversity among male-and female-headed cocoa households and its associated factors in the Juaboso-Bia landscape
Authors: Batame Michael 
Published: June 2023

Abstract
Malnutrition is a wicked problem that affects every country in the globe, affecting one in three individuals, including Ghana. 690 million people were undernourished globally in 2019, according to estimates from the Food and Agriculture Organization (FAO). 50% of child mortality has been attributed to malnutrition. The study used mixed research methods to gather primary data to investigate dietary diversity distribution and food and nutrition security status among male and female-headed cocoa households and its associated factors. Through this study, it was revealed that 62.8% of the male-headed cocoa households had medium to high dietary diversity compared to their female counterpart 39.3%. Also, the male-headed cocoa households recalled eating legumes/nuts (13%) and milk products (18.5%) were consumed less, whereas female-headed cocoa households least consumed the following food groups: sugar/honey (17.5%), oil/fat/butter (17%), spices/tea/condiments (16.5%), eggs (12.5%), organic meat (8.5%), fruits (7.5%), legumes/nuts (7%), and milk product (4.5%). Moreover, the months that the male-headed households recalled facing severe food unavailability were in July, June, April, and May, however, for the female-headed households, the severe months were June, July, March, February, and January. Climate change/variability, unavailable lands, poverty, large household size, and gender stereotypes were factors promoting low dietary diversity among male and female-headed households. Furthermore, 91.7% of the male-headed households and 88.6% of the female-headed households shared that cocoa expansion affects crop diversification in the study area. This study recommends that the government should educate cocoa households on the utmost importance of eating balanced diets, and empower female-headed households.

Abstract
Purpose
To investigate the risk factors for the failure of nasal noninvasive ventilation (NIV) in infants with severe community acquired pneumonia (SCAP).
Methods
This was a case-control study from the Pediatric Intensive Care Unit of the National Children’s Regional Medical Center in Northeast China. Comprehensive data was sourced from all infants (28 days − 3 years) diagnosed with SCAP and using NIV as the initial ventilation therapy from 2017 to 2021. NIV failure referred to endotracheal intubation, infant death or termination of treatment.
Results
Among the 168 infants, the failure rate of NIV was 47.0%. After adjusting by a binary logistic regression model, neuromuscular disorder (NMD) (odds ratio 6.47, 95% confidence interval 1.06–39.56), alanine aminotransferase (ALT) (2.25, 1.15–4.39), the differences of respiratory rate-oxygenation (ΔROX) index < -0.41 (2.20, 1.06–4.55), the duration before start NIV (0.97, 0.94–0.99), and the initial FIO2 of NIV (1.05, 1.02–1.09) were associated with NIV failure (all P values < 0.05). The predictive ability of PRISM III score (area under curve 0.588, P = 0.049) and modified PIRO scale (0.615, P = 0.010) for intubation were significant, not included PELOD-2 score (0.584, P = 0.060). 19.0% (15/79) infants experienced late intubation (> 72 hours of admission), which correlated to a lower improvement rate (76.6% vs. 40.0%, P = 0.011).
Conclusions
NMD history, reduced ΔROX index, increased ALT, early use and higher initial FIO2 requirements for NIV were risk factors for intubation during NIV for infants.

Published: June 2023

Abstract
Peeled melon seeds are widely consumed and are export items for several countries. The present research was conducted to establish the appropriate packaging materials for nutrient retention and shelf stability of peeled melon seeds (Citrullus lanatus). Fresh melon seeds were peeled and stored in three packaging materials- (Hessian Brown Bag (HBB), Propylene Bag (GSB) and Transparent Polyethylene Bag (TPB) for three months. Functional properties, physiochemical properties and nutrient composition of the samples were determined at the onset and after 3 months using standard AOAC methods. There was no significant difference (p > 0.05) between the fresh and samples stored for 3 months in all the functional properties. Emulsion capacity decreased after 3 months, while emulsion stability increased. All the vitamins, minerals and approximate nutrients determined (except carbohydrates) decreased as the storage period increased. The indices of fat deterioration increased with the storage period. Both the storage period and the packaging material did not affect the magnesium and zinc contents; iron, manganese, vitamin B6 and vitamin A contents decreased with storage period. Melon seeds packaged in Hessian bag retained the highest amount of nutrients and was the least susceptible to deterioration by fat rancidity.

Published: June 2023

Abstract
The current classification of highway service areas is primarily based on qualitative analysis, which lacks consistent standards and fails to meet the requirements for operation and planning. This article proposes a classification method for highway service areas based on land use features and characteristics specific to these areas. POI (point of interest) data is obtained from a mapping platform, and surveys provide information on the area of highway service areas, distance from city centers, regional economic conditions, and population data. The approach involves utilizing Principal Component Analysis (PCA) to extract feature factors from the POI data, which are combined with the highway service area characteristics to form classification indicators. The clustering tendencies are analyzed using the Hopkins statistic, the number of clusters is determined using the elbow method, and the advantages and disadvantages of K-Means, Fuzzy C-means (FCM), and hierarchical clustering algorithms are assessed using the Calinski-Harabasz (CH) coefficient, Silhouette Coefficient (SC), and Davies-Bouldin (DB) index. Using data from 95 highway service areas in Shaanxi Province as an example, the article applies the K-Means, FCM, and hierarchical clustering algorithms to classify the types of highway service areas and conducts feature analysis for each type. The research findings indicate that the K-Means clustering algorithm outperforms the FCM and hierarchical clustering algorithms according to all three evaluation indicators. Therefore, the article employs the K-Means clustering algorithm to classify the 95 highway service areas in Shaanxi Province into three categories. The classification results obtained from this study provide a basis for the comprehensive development of highway service areas and the surrounding land. By offering a more refined and consistent classification method, this research addresses the current issues and supports improved operation and planning of highway service areas.

Authors: Petersen Franziska Catharina , Broekaert Ilse Julia , Hünseler Christoph 
Published: June 2023

Abstract
Purpose:
The aim was to evaluate quality of life (QoL) in paediatric coeliac disease (CeD) and inflammatory bowel disease (IBD) patients and determine factors contributing to QoL.
Methods:
Children (3–18 years) with either CeD or IBD and their parents filled in two questionnaires: the PedsQL™ 4.0 SF 15 (SF 15) and the PedsQL™ 3.0 GIS Scale (GIS). The scores were compared and correlated with clinical data.
Results:
220 participants were enrolled (CeD: n = 67; IBD: n = 52). QoL in children with CeD or IBD are comparable between total scores (SF 15 total score: 83.49 (CeD) vs. 85.39 (IBD) (p = 0.13); GIS total score: 83.95 (CeD) vs. 88.25 (IBD) (p = 0.09)). However, differences in subcategories were found. In CeD patients, Emotional Functioning (p = 0.04), Food and Drink Limits (p < 0.01), Trouble Swallowing (p = 0.02) and Heart Burn and Reflux (p < 0.01) were related to a poorer QoL. Comparing perceptions of parents, similar results of QoL were shown (CeD: Emotional Functioning (p = 0.02), Food and Drink Limits (p < 0.01); IBD: Blood in Poop scale (p < 0.01)). According to univariate regression, SF 15 total scores of children with IBD and their parents (p < 0.01) and GIS total scores (children: p < 0.03, parents: p < 0.01) were lower when calprotectin was elevated. Total SF 15 scores reported by parents of children with CeD were lower when transglutaminase-IgA was elevated (p = 0.02).
Conclusions:
Although both diseases may vary in their clinical appearance and limitations in daily life, perceptions of QoL are comparable to each other. Yet, we discovered disease specific domains contributing to a lower QoL.

6D Pose Estimation of Weakly Textured Object Driven by Decoupling Analysis and Algorithm Fusion Strategy
Authors: 郑天宇 江苏科技大学 , Zhang Sheng-Wen , Wang Yan-Yan 
Published: June 2023

Abstract
In complex industrial scenes, the 6D pose estimation of weakly textured objects is characterized by difficult feature extraction and a high cost of dataset production. These challenges make it difficult to ensure the accuracy and reliability of the 6D pose estimation. To address these issues, a weakly textured object pose estimation method driven by decoupling analysis and algorithm fusion strategy is proposed in this paper. In this approach, the 6D pose estimation is decoupled. Firstly, a synthetic dataset is created using rendering and sampling techniques, and the relevant initial pose information is recorded. Then, a CBAM-CDAE network is proposed, which incorporates the Convolutional Block Attention Module (CBAM) into the Convolutional Denoising Autoencoder (CDAE). This network suppresses irrelevant features and enhances the expressive power of the network. Additionally, the hierarchical network structure and sliding window operation from the Swin Transformer network are introduced to improve the overall performance. The trained CBAM-CDAE network is used to generate potential vector codebooks corresponding to the template samples. The trained M-ST instance segmentation network is employed to obtain object bounding box and mask information, which are utilized to calculate the initial pose estimation. Extensive experiments are conducted on the T-LESS dataset to validate the proposed method. The proposed method accomplishes highly accurate while maintaining detection speed, the method achieves improved accuracy and reliability. The experimental results provide strong evidence of the method's performance and highlight its potential for practical applications.

Abstract
Hypothalamic gonadotropin-releasing hormones (GnRH) neurons are central regulators of fertility and integrate endogenous hormonal status with environmental cues to ensure reproductive success. Here, we found that a novel population of extra-hypothalamic GnRH neurons in the olfactory bulb of adult mice and humans (GnRHOB) can mediate social recognition. We show that GnRHOB neurons extend neurites into the vomeronasal organ and olfactory epithelium and project to the hypothalamic median eminence. We demonstrate that male GnRHOB neuronsexpress chemosensory vomeronasal and olfactory receptors, are activated by female odors in vivo, and mediate gonadotropin release in response to female urine. We find that male preference for female odors is enhanced upon chemogenetic activation of GnRHOB neurons, impaired after genetic inhibition or ablation of these cells and relies on GnRH signaling in the posterodorsal medial amygdala. Taken together, these results establish GnRHOB neurons as a central regulatory hub regulating fertility, sex recognition, and mating in males.

Published: June 2023

Abstract
In this paper, we consider a system of two degenerate wave equations coupled through the velocities, only one of them being controlled. We assume that the coupling parameter is sufficiently small and we focus on null controllability problem. To this aim, using multiplier techniques and careful energy estimates, we first establish an indirect observability estimate for the corresponding adjoint system. Then, by applying the Hilbert Uniqueness Method, we show that the indirect boundary controllability of the original system holds for a sufficiently large time.

Uranium tailings in the Istiqlol city: history, problems, solutions
Authors: Khakimova N. U. , Zoitova M. A. 
Published: June 2023

The article provides an overview of the problems associated with the uranium tailings in Istiqlol city. Many uranium heritage sites in Central Asia, including the uranium tailings in Istiqlol, hadn’t been mothballed before the collapse of the USSR. The burial complex consists of a quarry, dumps of the “Poor Ores Factory”, an unpreserved open mine, destroyed industrial buildings and four tailings which contain 12 million tons of the uranium production waste. In the area of the tailings, the ambient dose rate of gamma radiation is 0.5–0.6 μSv/h, and at some points it reaches 3.0–4.0 μSv/h. The average annual radon emission from the surface is estimated at 3.9×1011 Bq/year. The contaminated areas also include the Sarym-Sakhly Sai stream, mine, industrial and quarry waters, which are characterized by an increased content of 234U, 238U and 226Ra. The facilities aren’t physically fenced, allowing free access for the public and livestock. Natural disasters such as mudflows, landslides, and earthquakes can lead to an ecological disaster. Attention is paid to the ways of solving problems such as monitoring radionuclides in water, soil, and air; working with the local population to inform and involve them in rehabilitation work; donors search. The Program for the Implementation of the National Concept for the Rehabilitation of Tailings of Uranium Ore Processing Wastes for 2016–2024 was developed and approved by the Government of the Republic of Tajikistan to minimize the radiation impact on the population and the environment. Implementation of the Program requires significant financial investments and trained personals in the field of radiation safety. Only through the joint efforts of the state, population and international organizations is it possible to fully carry out rehabilitation works. Only by joint the state, public, and international organizations efforts, it is possible to solve these problems. Also, one of the main reasons why the population had received unnecessary overexposure was its ignorance of the danger of using water, soil and building materials contaminated with radionuclides. Therefore, the culture of radiation safety should be studied starting from middle school, where students will be taught about ionizing radiation and possible ways of exposure. Then, both cases of intake of radionuclides into the body, which could have been avoided, and radiophobia among the population living near the extraction and processing of uranium ore, will be much lower. Some social and economic aspects are also touched upon.
Performance assessment of methods to estimate initial hydrologic conditions for event-based rainfall-runoff modelling
Authors: Manikanta Velpuri , Umamahesh N. V. 
Published: June 2023

Abstract

Event-based hydrological models are extensively adopted for the estimation of design floods and in operational flood forecasting frameworks. However, an accurate estimation of the initial hydrologic condition (IHC) is essential in enhancing the predictive capability of an event-based hydrological model. Hence, in this study, IHCs of an event-based conceptual model are estimated using two different methods: (1) assimilation of observed variables such as streamflow and soil moisture using an ensemble Kalman filter and (2) states obtained from the continuous model calibrated using four different calibration metrics. The observed flood events at the Jagdalpur catchment are simulated using a conceptual hydrologic model setup at two spatial resolutions (lumped and semi-distributed). The results of the study demonstrate that IHCs estimated by the continuous models perform better than those obtained through data assimilation. The performance of semi-distributed event-based models was found to be outperforming their lumped counterparts demonstrating the advantage of increased model resolution. The states obtained from the continuous models calibrated using Nash–Sutcliffe Efficiency (NSE) are performing well in initialising the event-based models. The median efficiency of the semi-distributed event-based model (based on states from the NSE calibrated continuous model) is 0.91 and 0.77 during calibration and validation periods, respectively.

Published: June 2023

Abstract

Operation conditions considerably affect the removal efficiency of wastewater treatment systems, and yet we still lack data on how these systems function under extreme dilution rates and climatic conditions at high altitudes. Here, we applied two modified First-Stage French Vertical Flow Constructed Wetlands (FS-FVFCWs) for sewage treatment in Northern Tropical Andes. Specifically, within 18 months, we conducted a pilot-scale experiment at two hydraulic loading rates (HLRs) of 0.94 and 0.56 m d−1, representing 2.5 and 1.5 times the recommended design values, with two different feeding/resting periods to investigate the impact of HLRs and operational strategy on system performance. We found that chemical oxygen demand (COD) and total suspended solids (TSS) removal was satisfactory, with average values of 53 ± 18 and 69 ± 16%, respectively. Moreover, reducing HLRs resulted in higher removal efficiency for COD, from 46 ± 15 to 64 ± 15%, but had no impact on TSS removal, with 3 days of feeding and 6 days of resting. For an equal time of feeding and resting, COD and TSS removals were not affected by the modified HLR. These findings suggest that high HLRs can be applied to FS-FVFCW without compromising the system operation and obtaining satisfactory results, leading to opportunities to reduce areas and costs.
