Choline Supplementation Modifies the Effects of Developmental Alcohol Exposure on Immune Responses in Adult Rats
Authors: Baker Jessica A. , Breit Kristen R. , Bodnar Tamara S. , Weinberg Joanne , Thomas Jennifer D.
Published: July 2022

Prenatal alcohol exposure can disrupt the development of numerous systems, including the immune system. Indeed, alterations in cytokine levels may contribute to the neuropathological, behavioral, and cognitive problems, and other adverse outcomes observed in individuals with fetal alcohol spectrum disorders. Importantly, supplementation with the essential nutrient choline can improve performance in hippocampal-dependent behaviors; thus, the present study examined the effects of choline on plasma and hippocampal cytokines in adult rats exposed to ethanol in early development. From postnatal day (PD) 4–9 (third trimester equivalent), pups received ethanol (5.25 g/kg/day) or Sham intubations. Subjects were treated with choline chloride (100 mg/kg/day) or saline from PD10–30. On PD60, plasma and hippocampal tissue was collected before and after an immune challenge (lipopolysaccharide (LPS); 50 ug/kg). Prior to the immune challenge, ethanol-exposed subjects showed an overall increase in hippocampal pro-inflammatory cytokines, an effect mitigated by choline supplementation. In contrast, in the plasma, choline reduced LPS-related increases in pro-inflammatory markers, particularly in ethanol-exposed subjects. Thus, early choline supplementation may modify both brain and peripheral inflammation. These results suggest that early choline can mitigate some long-term effects of ethanol exposure on hippocampal inflammation, which may contribute to improved hippocampal function, and could also influence peripheral immune responses that may impact overall health.
Implications of Resveratrol in Obesity and Insulin Resistance: A State-of-the-Art Review
Authors: Barber Thomas M. , Kabisch Stefan , Randeva Harpal S. , Pfeiffer Andreas F. H. , Weickert Martin O.
Published: July 2022

Background: Resveratrol is a polyphenol chemical that naturally occurs in many plant-based dietary products, most notably, red wine. Discovered in 1939, widespread interest in the potential health benefits of resveratrol emerged in the 1970s in response to epidemiological data on the cardioprotective effects of wine. Objective: To explore the background of resveratrol (including its origins, stability, and metabolism), the metabolic effects of resveratrol and its mechanisms of action, and a potential future role of dietary resveratrol in the lifestyle management of obesity. Data sources: We performed a narrative review, based on relevant articles written in English from a Pubmed search, using the following search terms: “resveratrol”, “obesity”, “Diabetes Mellitus”, and “insulin sensitivity”. Results: Following its ingestion, resveratrol undergoes extensive metabolism. This includes conjugation (with sulfate and glucuronate) within enterocytes, hydrolyzation and reduction within the gut through the action of the microbiota (with the formation of metabolites such as dihydroresveratrol), and enterohepatic circulation via the bile. Ex vivo studies on adipose tissue reveal that resveratrol inhibits adipogenesis and prevents the accumulation of triglycerides through effects on the expression of Peroxisome Proliferator-activated Receptor γ (PPARγ) and sirtuin 1, respectively. Furthermore, resveratrol induces anti-inflammatory effects, supported by data from animal-based studies. Limited data from human-based studies reveal that resveratrol improves insulin sensitivity and fasting glucose levels in patients with Type 2 Diabetes Mellitus and may improve inflammatory status in human obesity. Although numerous mechanisms may underlie the metabolic benefits of resveratrol, evidence supports a role in its interaction with the gut microbiota and modulation of protein targets, including sirtuins and proteins related to nitric oxide, insulin, and nuclear hormone receptors (such as PPARγ). Conclusions: Despite much interest, there remain important unanswered questions regarding its optimal dosage (and how this may differ between and within individuals), and possible benefits within the general population, including the potential for weight-loss and improved metabolic function. Future studies should properly address these important questions before we can advocate the widespread adoption of dietary resveratrol supplementation.

Published: July 2022

Glioblastoma (GBM), a highly lethal form of adult malignant gliomas with little clinical advancement, raises the need for alternative therapeutic approaches. Lipid-soluble vitamins have gained attention in malignant brain tumors owing to their pleiotropic properties and their anti-cancer potential have been reported in a number of human GBM cell lines. The aim of this paper is to systematically review and describe the roles of various biomarkers regulated by lipid-soluble vitamins, such as vitamins A, D, E, and K, in the pathophysiology of GBM. Briefly, research articles published between 2005 and 2021 were systematically searched and selected from five databases (Scopus, PubMed, Ovid MEDLINE, EMBASE via Ovid, and Web of Science) based on the study’s inclusion and exclusion criteria. In addition, a number of hand-searched research articles identified from Google Scholar were also included for the analysis. A total of 40 differentially expressed biomarkers were identified from the 19 eligible studies. The results from the analysis suggest that retinoids activate cell differentiation and suppress the biomarkers responsible for stemness in human GBM cells. Vitamin D appears to preferentially modulate several cell cycle biomarkers, while vitamin E derivatives seem to predominantly modulate biomarkers related to apoptosis. However, vitamin K1 did not appear to induce any significant changes to the Raf/MEK/ERK signaling or apoptotic pathways in human GBM cell lines. From the systematic analysis, 12 biomarkers were identified that may be of interest for further studies, as these were modulated by one or two of these lipid-soluble vitamins.
Protective Effect of Bilberry Anthocyanin Extracts on Dextran Sulfate Sodium-Induced Intestinal Damage in Drosophila melanogaster
Authors: Zhang Guocai , Gu Yunyao , Dai Xianjun
Published: July 2022

Inflammatory bowel disease (IBD) is a chronic recurrent disease that can be controlled by various natural extracts. Anthocyanins (ANCs) from bilberry have significant antioxidant capacity and are widely used as food colors and antioxidants. In this study, we investigated the protective effects of bilberry anthocyanin extracts (BANCs) against dextran sulphate sodium (DSS)-induced intestinal inflammation in a Drosophila melanogaster (D. melanogaster) model, and the effects on the lifespan, antioxidant capacity, intestinal characteristics, and microbiome and gene expression profiles were analyzed to elucidate the underlying biological mechanisms. In DSS-induced normal and axenic D. melanogaster, BANCs significantly increased the survival rate, maintained the intestinal morphology and integrity, and reduced the number of dead intestinal epithelial cells and the ROS level of these cells. BANC supplementation had no significant effect on the intestinal microflora of DSS-induced D. melanogaster, as demonstrated by a 16S rDNA analysis, but improved the antioxidant capacity by activating the relative gene expression of NRF2 signaling pathways in the intestine of D. melanogaster with DSS-induced inflammation. Therefore, the results demonstrate that BANCs effectively alleviate intestinal inflammatory injury induced by DSS and improve the antioxidant capacity of D. melanogaster by modulating NRF2 signaling pathways, and could thus promote the application of BANCs as functional foods.

Published: July 2022

Menopause syndrome causes a decline in the quality of life of postmenopausal women. Hormone therapy is recommended for the treatment of menopausal syndromes. However, it has several side effects. Soybean has been safely used to relieve the symptoms of menopause. Lettuce has antidiabetic and anti-inflammatory effects and improves sleep quality. Natural nitric oxide metabolites are produced through fermentation, which increases the effectiveness of the functional substances. This study assessed the alleviation of menopausal syndrome symptoms by natural nitric oxide-containing soybean lettuce extract using the Kupperman index. This study included adult women with menopausal syndrome and a Kupperman index of ≥15. After a four-week study with 40 participants, the final analysis included 39 participants in the experimental group (n = 19) and the placebo group (n = 20). Body mass index, waist circumference, and the total cholesterol, low-density and high-density lipoprotein cholesterol, and triglyceride levels were not altered before and after treatment in both groups. There was a significant decrease in the Kupperman index after treatment in the experimental group, but no significant change was observed in the placebo group. Soybean lettuce extract alleviates menopause syndrome without any special side effects.

Pharmacy Students’ Experiences with an Interactive Video Platform to Develop Clinical Reasoning
Authors: Cornelison Bernadette , Baldry Adam , Axon David R.
Published: July 2022

Activities used to evaluate clinical reasoning include the use of standardized patients, role play, and case studies. To provide a standardized student experience at a lower cost than a standardized patient, standardized patients were developed using an interactive video platform. The purpose of this article is to report pharmacy students’ perceptions of the interactive video standardized patients used to practice applying clinical reasoning in a self-care therapeutics course. Students participated in the following five methods to assess clinical reasoning: case studies, interactive patient videos, role play, case creation, and Zoom® polls. Four of the five methods (case studies, interactive patient videos, role play, and case creation) were used in small breakout groups consisting of two to three students. Upon completion of the small group work, Zoom® polls assessed the clinical reasoning of the entire class. Students completed a survey that assessed their level of agreement with 17 statements about the course on a five-point Likert scale and 2 questions that asked the students to rank the activities based on their experiences. There were 127 students that took the self-care therapeutics course, and 112 completed the survey (88%). Overall, the students preferred the Zoom® poll activity; however, of the four different methods utilized within the small breakout groups, the findings of our survey indicated that students preferred to receive fully written-out patient cases followed by the interactive patient videos. Additionally, the students thought that the written-out patient cases and interactive patient videos were most efficient for learning and recall. The interactive patient videos may be an alternative activity that allows students to demonstrate and assess their clinical reasoning for each patient case, in addition to seeing how this impacted their patient’s outcome.

Published: July 2022

Silicon (Si) application has great potential to improve salt tolerance in a variety of crop plants. However, it is unclear how Si influences the responses of contrasting rice cultivars when exposed to excessive salt. Here, we investigated the functions of Si in alleviating the negative effects of salt stress on two contrasting rice cultivars, namely BRRI dhan48 (salt-sensitive) and Binadhan-10 (salt-tolerant). Rice seedlings was pre-treated with three doses of Si (as silicic acid; 0, 1 and 2 mM) for 14 days at one-day interval before being exposed to salt stress (10 dSm−1) in a sustained water bath system. The results demonstrated that the seedlings of BRRI dhan48 and Binadhan-10, respectively exhibited substantial reductions in shoot height (16 and 9%), shoot fresh weight (64 and 43%) and shoot dry weight (50 and 39%) under salinity. Intriguingly, BRRI dhan48 pre-treated with 1 and 2 mM Si, respectively, showed a higher increase in shoot height (SH) (by 25.90 and 26.08%) as compared with Binadhan-10 (by 3 and 8%) under salt stress compared with their respective controls. Data revealed that a comparatively higher improvement in the growth performances of the salt-induced Si pre-treated BRRI dhan48 than that of Binadhan-10. For example, 1 and 2 mM of Si treatments significantly attributed to elevated leaf relative water content (RWC) (13 and 22%), proline (138 and 165%), chlorophyll a (42 and 44%), chlorophyll b (91 and 72%), total chlorophyll (58 and 53%) and carotenoids (33 and 29%), and recovery in the reductions of electrolyte leakage (13 and 21%), malondialdehyde content (23 and 30%) and shoot Na+/K+ ratio (22 and 52%) in BRRI dhan48 compared with Si-untreated control plants under salt stress. In addition, we found salt-tolerant Binadhan-10 also had enhanced RWC (9 and 19%), proline (12 and 26%) with pre-treatment with 1 and 2 mM of Si, respectively, under salt stress, while no significant differences were noticed in the case of photosynthetic pigments and Na+/K+ ratio. Our results showed that Si supplementation potentiated higher salt-tolerance ability in the salt-sensitive BRRI dhan48 as compared with salt-tolerant Binadhan-10. Thus, Si application could be highly beneficial in the growth recovery of the salinity-affected salt-sensitive high yielding rice cultivars in the saline-prone areas.

Published: July 2022

Many researchers and scientists have contributed significantly to provide structural and molecular characterizations of biochemical interactions using microscopic techniques in the recent decade, as these biochemical interactions play a crucial role in the production of diverse biomaterials and the organization of biological systems. The properties, activities, and functionalities of the biomaterials and biological systems need to be identified and modified for different purposes in both the material and life sciences. The present study aimed to review the advantages and disadvantages of three main branches of microscopy techniques (optical microscopy, electron microscopy, and scanning probe microscopy) developed for the characterization of these interactions. First, we explain the basic concepts of microscopy and then the breadth of their applicability to different fields of research. This work could be useful for future research works on biochemical self-assembly, biochemical aggregation and localization, biological functionalities, cell viability, live-cell imaging, material stability, and membrane permeability, among others. This understanding is of high importance in rapid, inexpensive, and accurate analysis of biochemical interactions.
The Influence of Rotating Speed on the Sealing Characteristics of a Liquid-Sealing Impeller for a Liquid Oxygen Turbopump

Published: July 2022

In order to explore the influence of rotating speed on the internal flow and sealing characteristics of the liquid-sealing impeller for a liquid oxygen turbopump of a rocket engine, unsteady numerical simulations of the flow characteristics and sealing performance of the first-stage liquid-sealing impeller for a liquid oxygen turbopump under liquid phase conditions were performed. The results show that the pressurization value increases with the increase in the rotating speed. The first-stage liquid-sealing impeller, whose structure is symmetrically distributed along the center of the rotation axis, tends to be an isobaric seal at a rotating speed of 12,000 rpm, and when the rotating speed is decreased or increased, it enters the leakage state or negative pressure sealing state, respectively. The matching relationship between the rotating speed and inlet pressure has a significant effect on the pressurization value, pressurization coefficient and leakage flow rate. Under the working condition with a good match between the rotating speed and inlet pressure, the pressurization value increases significantly and the leakage flow rate decreases significantly, and the pressurization coefficient is stable between 0.88 and 0.89. The empirical formulas proposed by Wood and the Shanghai Research Institute of Chemical Industry (1979) have high reference values for the design of the liquid-sealing impeller with a flow channel (groove) and retainer.

Published: July 2022

This study aimed to explore the enzymatic acylation of dihydromyricetin (DHM) to synthesized DHM derivatives with a different substituted carbon chain to improve its liposolubility. In the presence of Lipozyme TL IM, DHM was butyrylated in a 96.28% conversion in methyl tert-butyl ether under the optimized conditions (molar ratio of DHM to vinyl butyrate, 1:20; lipase dosage, 0.4 U/mg DHM; temperature, 50 °C; stirrer speed, 200 rpm; reaction time, 72 h). Liquid chromatography-mass spectrometry (LC-MS) and nuclear magnetic resonance (NMR) spectroscopy revealed that two acylation products were formed; these were 7-O-acyl-DHM and 3-O-acyl-DHM. In addition, the liposolubility of the DHM derivatives increased with the increase in the substituted carbon chain length; their antioxidant activities were higher than that of DHM in the lecithin peroxidation system, and C8-DHM had a better effect. Therefore, enzymatic acylation broadens the application of DHM in a lipid system in the food field.
The United Arab Emirates’ Religious Soft Power through Ulema and Organizations
Authors: Baycar Hamdullah , Rakipoglu Mehmet
Published: July 2022

The United Arab Emirates (UAE) proposes “peaceful” religious discourse by supporting religious scholars such as Hamza Yusuf and Abdallah bin Bayyah and institutions such as the Forum for Promoting Peace in Muslim Societies and the Emirates Fatwa Council. The UAE has attempted to present itself as promoting a moderate form of Islam to counter political Islam. This study is based on data from religious verdicts (fatwās), speeches, and conference records of these scholars and institutions. The main point of the research is to show to what extent providing additional support to recently established religious institutions and emerging scholars is used as soft power to promote the UAE’s version of Islam and present the UAE as a moderate and tolerant country. Applying critical discourse analysis, the study aims to uncover the existing connection between emerging religiopolitical discourse and UAE-based legal verdicts of scholars (ulamā) and the organizations that they initiated. This study further argues that “moderate Islam” and “tolerance”, used as religious soft power, are other tools that the UAE has applied in line with expectations for influence and power-seeking based on small state theory.
Mining Industry Corporate Social Responsibility to Education Development

Published: July 2022

The impact of mining industries’ operations on different areas is easy to be noticed. Thus, nowadays different research considering ecology, economy, society, or engineering is performed in light of mining industries. However, the impact on education development is not the first choice. Thus, the aim of this paper is the verification of possibility to indicate the main key factors (activities) in the mining industry, that are in accordance with the CSR doctrine and are capable of ensuring education development. To reach this purpose, KGHM Polska Miedź SA was selected for the research, as an example of a mining company operating on a global scale. Then, the appropriate CSR standard “Principles for Global Corporate Responsibility, Bench Marks for Measuring Business Performance” was a basis for the operationalization process to assure the research tool, that defines the list of the activities in accordance with CSR doctrine. The obtained research tool was used to perform the survey, which indicated the key factors that assure education development. As a result, over 65 key factors were indicated. Generally, the factors considered, e.g., free access to education for workers, suppliers, and vendors, do not affect the education of children and young workers, as does preparing company documents in language adequate to the operating area.
Submesoscale Currents from UAV: An Experiment over Small-Scale Eddies in the Coastal Black Sea
Authors: Yurovsky Yury Yu. , Kubryakov Arseny A. , Plotnikov Evgeny V. , Lishaev Pavel N.
Published: July 2022

A commercial unmanned aerial vehicle (UAV) is used for coastal submesoscale current estimation. The measurements were conducted in the Black Sea coastal area with a DJI Mavic quadcopter operated in self-stabilized mode at different look geometry (200–500-m altitude, 0–30∘ incidence angle). The results of four flights during 2020–2021 are reported. Some scenes captured a train of or individual eddies, generated by a current flowing around a topographic obstacle (pier). The eddies were optically visible due to the mixing of clear and turbid waters in the experiment area. Wave dispersion analysis (WDA), based on dispersion shell signature recognition, is used to estimate the sea surface current in the upper 0.5-m-thick layer. The WDA-derived current maps are consistent with visible eddy manifestations. The alternative method, based on 4D-variational assimilation (4DVAR), agrees well with WDA and can complement it in calm wind conditions when waves are too short to be resolved by the UAV sensor. The error of reconstructed velocity due to the uncontrolled UAV motions is assessed from referencing to static land control points. At a 500-m altitude and 7–10 m s−1 wind speed (reported by a local weather station for 10-m height), the UAV drift velocity, or the bias of the current velocity estimate, is about 0.1 m s−1, but can be reduced to 0.05 m s−1 if the first 10 s of the UAV self-stabilization period are excluded from the analysis. The observed anticyclonic eddies (200–400 m in diameter with 0.15–0.30 m s−1 orbital velocity) have an unexpectedly high Rossby number, Ro∼15, suggesting the importance of nonlinear centrifugal force for such eddies and their significant role in coastal vertical transport.
Mapping Arable Land and Permanent Agriculture Extent and Change in Southern Greece Using the European Union LUCAS Survey and a 35-Year Landsat Time Series Analysis

Published: July 2022

Agricultural land extent and change information is needed to assess food security, the effectiveness of land use policy, and both environmental and societal impacts. This information is especially valuable in biodiversity hotspots such as the Mediterranean region, where agricultural land expansion can result in detrimental effects such as soil erosion and the loss of native species. There has also been a growing concern that changing agricultural extent in fire-prone regions of the Mediterranean may increase fire risk due to accumulation of fuel in abandoned areas. In this study, we assessed the extent and change of agricultural land in Southern Greece from 1986 to 2020 using a combined European Land Use/Cover Area frame Survey (LUCAS) and Landsat time series approach. The LUCAS data and Landsat spectral-temporal metrics were used to train a random forest classifier, which was used to classify arable land and permanent agriculture (e.g., olive orchards, vineyards) at annual time steps. A post-processing step was taken to reduce spurious landcover class transitions using transition likelihoods and annual class membership likelihoods. A validation dataset consisting of 2666 samples, identified via a stratified random sampling approach and high-resolution imagery and time series analysis, were used to evaluate stable and change strata accuracies. Overall accuracies were greater than 70% and strata-specific accuracies were highly variable between stable and change strata. The results show that southern Greece has experienced a recent gain in arable land (~12,000 ha from ~2009–2020) and a much larger gain in permanent agriculture (>115,000 ha from ~1993–2020). Arable land loss mainly occurred from 1987 to ~2002 when extent decreased by 15,000 ha, of which 66% was abandoned. The semi-automated approach described in this paper provides a promising approach for monitoring agricultural land change and enabling assessments of agriculture policy effectiveness and environmental impacts.
Towards an Integrated Observational System to Investigate Sediment Transport in the Tidal Inlets of the Lagoon of Venice

Published: July 2022

An observation system integrating satellite images, in situ water parameters and hydrodynamic measurements was implemented in a tidal inlet of the Venice Lagoon (Northern Adriatic Sea, Italy). The experimental infrastructure was developed to autonomously investigate suspended sediment dynamics in the two channels of the Lido inlet in relation to the longshore currents in the littoral zone and the tidal circulation along the lagoon channel network. It provided time series of turbidity at the surface, water flow and acoustic backscatter, which was converted into turbidity along the vertical column during different tidal phases and meteo-marine conditions. Accurate turbidity maps were derived from Sentinel-2 (Copernicus) and Landsat 8 (NASA) satellites. Long-term in situ data from field surveys enabled the calibration and intercalibration of the instrumental setup and validation of satellite-derived products. Time series from the instrumental network were analyzed in order to evaluate the temporal variability of suspended sediment in relation to tidal phases and the different meteo-marine conditions. The integration of available datasets with satellite images also permitted the testing of the methodology for a 3-D reconstruction of the suspended sediment pattern in calm sea conditions, under the effect of the sole hydrodynamical forcing. Remotely sensed data provide a synoptic distribution of turbidity in the inlet area allowing the analysis of the surficial patterns of suspended sediment and the inferring of information on the transport processes at different spatial scales. In calm sea conditions, the results show that the transport is driven by tidal currents with a net seaward transport related to a larger export of materials from the northern basin of the Lagoon of Venice. During typical northeasterly storms, materials mobilized on the beaches and in the shoreface are transported into the inlet and distributed into the lagoon channel network, following the flood tidal currents and determining net import of materials. The multitude of information provided by this system can support research on aquatic science (i.e., numerical simulations) and address end-user community practices. The ecosystem management will also benefit operational purposes, such as the monitoring of morphological transformations, erosion processes and planning of coastal defense in the future scenarios of sea level rise. The developed approach will also help to understand how the regulation of the inlet flow introduced by the operation of the flood barriers will affect the fluxes of particles and, in the long term, the lagoon morphodynamics.
Using of Remote Sensing-Based Auxiliary Variables for Soil Moisture Scaling and Mapping
Authors: Zhao Zebin , Jin Rui , Kang Jian , Ma Chunfeng , Wang Weizhen
Published: July 2022

Soil moisture is one of the core hydrological and climate variables that crucially influences water and energy budgets. The spatial resolution of available soil moisture products is generally coarser than 25 km, which limits their hydro-meteorological and eco-hydrological applications and the management of water resources at watershed and agricultural scales. A feasible solution to overcome these limitations is to downscale coarse soil moisture products with the support of higher-resolution spatial information. Although many auxiliary variables have been used for this purpose, few studies have analyzed their applicability and effectiveness in arid regions. To this end, we comprehensively evaluated four commonly used auxiliary variables, including NDVI (Normalized Difference Vegetation Index), LST (Land Surface Temperature), TVDI (Temperature Vegetation Dryness Index), and SEE (Soil Evaporative Efficiency), against ground-based soil moisture observations during the vegetation growing season in the Heihe River Basin, China. Performance metrics indicated that SEE is most sensitive (R2 ≥ 0.67) to soil moisture because it is controlled by soil evaporation limited by the available soil moisture. The similarity of spatial patterns also showed that SEE best captures soil moisture changes, with the STD (standard deviation) of the HD (Hausdorff Distance) less than 0.058 when compared with PLMR (Polarimetric L-band Multi-beam Radiometer) soil moisture products. In addition, soil moisture was mapped by RF (Random Forests) using both single auxiliary variables and 11 types of multiple auxiliary variable combinations. SEE was found to be the best auxiliary variable for scaling and mapping soil moisture with accuracy of 0.035 cm3/cm3. Among the multiple auxiliary variables, the combination of LST, NDVI, and SEE was found to best enhance the scaling and mapping accuracy of soil moisture with 0.034 cm3/cm3.
Shallow Regolith Structure and Obstructions Detected by Lunar Regolith Penetrating Radar at Chang’E-5 Drilling Site
Authors: Feng Jianqing , Siegler Matthew A. , White Mackenzie N.
Published: July 2022

This work analyzes the observations from the Lunar Regolith Penetrating Radar (LRPR) onboard Chang’E-5 to reconstruct the subsurface structure of the regolith under the lander at the drilling site. This is the first stationary Ground-Penetrating Radar (GPR) array to operate on the Moon. Imaging results of pre-drilling and post-drilling measurements show that the thickness of local regolith is larger than 2 m. Within the LRPR’s detection range, we do not find any continuous layer. Instead, irregular, high-density zones are identified in the regolith. Two of these zones are on the drilling trajectory at ~30 cm and ~70 cm, consistent with the recorded drilling process. We speculate a rock fragment from the deeper, high-density zone obstructed the drill, which led to an early termination of the drilling. Based on our interpretation of subsurface structure, we modeled the LRPR echoes using a finite-difference time-domain method. The same imaging algorithm was also applied to the simulation data. The modeled data verify our inference of the regolith structure under the lander.
CO2 Capture over Activated Carbon Derived from Pulverized Semi-Coke
Authors: Jing Jieying , Zhao Zemin , Zhang Xuewei , Feng Jie , Li Wenying
Published: July 2022

Pulverized semi-coke was employed as raw material to prepare activated carbon via steam activation and evaluated as a CO2 adsorbent. The effects of the preparation parameters including demineralization, activation temperature, activation time and steam flow on the structure and performance of the synthesized activated carbon were investigated. It was found that the microporous structure of activated carbon was greatly influenced by demineralization order and activation conditions. Demineralization before activation significantly increased the microporous structure of the activated carbon, which was ascribed to the removal of the inorganic fraction. Compared to the commercial activated carbon, activated carbon obtained by employing 150 mL/min steam to treat the demineralized pulverized semi-coke at 700 °C for 70 min possessed a higher CO2/N2 selectivity of 34.4 and good cyclic performance, which was due to its narrow microporosity of 0.55 nm. Furthermore, it was proved that a pore size of smaller than 1 nm is favorable for CO2 sorption.
The Association between Religious Beliefs and Food Waste: Evidence from Chinese Rural Households
Authors: Qian Long , Li Feng , Zhao Xia , Liu Hongbo , Liu Xiaojie
Published: July 2022

This paper investigates the Chinese rural household food waste issue from the unique perspective of religious beliefs based on 1380 samples in 26 provinces in mainland China. By using the count regression approach model, it is found that about 2.30% of the home meal is wasted on average for Chinese rural households. The empirical results reveal that religion has a significantly negative impact on residents’ food wastage, and religious rural households waste less food than their counterparts. Taking into account the possible omission of variables and selection bias, the above conclusion is still valid. Additionally, male household heads, small household size, young families, bad food storage conditions, and the poorer convenience of buying foods are positively related to the higher food waste rate in rural China. Thus, the study provides evidence that religiosity plays a positive role in reducing food waste in rural China. As most of the world’s population is religious to some extent, the finding may also apply to other countries or regions, and it implies that religion and sustainable food consumption are closely related.

Published: July 2022

Outdoor urban lighting design is a complex issue. It involves multiple aspects (energy consumption, lighting pollution, aesthetics, and safety) that must be balanced to make sustainable decisions. Although the energy and environmental issues assumed a driving role in the optimization of the urban lighting design, its impact on the psychophysical well-being of individuals has received less attention. Artificial lighting has been shown to add several meanings to an individual’s experience of space: affective (affect, emotion, mood), cognitive (attention, imagination, perception), associative (memory, judgment), and motivational (closeness, openness, communication). Traditionally, studies on the effects of lighting on individuals’ emotions have mainly focused on indoor spaces, while the present study aims to investigate the influence of lighting on individuals’ emotions in an outdoor environment. Participants experienced a simulated urban park through virtual reality. Specifically, the urban park was shown with different combinations of overall illuminance (high vs medium vs low) and correlated colour temperature (CCT) (warm vs intermediate vs cool). For each combination, participants were asked to judge how they felt. In general, results showed that high-intensity cool light made participants more nervous, while warm light made individuals feel more tired and less motivated to explore the park. In contrast, an intermediate CCT at low or medium illuminance impacted individuals positively. Finally, it was found that participants’ mood predicted the impact that park lighting would have on them. These results suggest that assessing the influence of lighting on individuals’ emotions allows the decision-makers to implement the type of artificial lighting that will simultaneously safeguard both the well-being of individuals and the environment.
Assessing the Compensatory Potentiality of Hot Spring Tourism in the COVID-19 Post-Pandemic Environment
Authors: Huang Xinjia , Zhang Yang , Li Chaojun
Published: July 2022

Considering the public health crisis induced by the COVID-19 disease, hot spring tourism has attracted more people who want to compensate for this themselves and seek restoration of health. Research regarding consumer experience and their psychological restoration from compensatory travel activities is lacking. To address this gap, a conceptual model is developed that links the compensatory experience quality and the perceived restorative value. The model was assessed using a sample of 631 tourists who visited hot spring resorts in the post-pandemic environment. Our findings confirm the positive influence of the quality of compensatory experience (CEQ) on perceived restorativeness (PR). In particular, the cognitive image and affective image partially mediated the effect of CEQ on PR.

Authors: Kim Doil , Kim Kabsung
Published: July 2022

This study examined the relationship between financial support and neighborhood regeneration in Korea. A questionnaire about neighborhood regeneration projects was administered to 175 Korean respondents in the regeneration field. Results found that the housing revitalization project needed more public funds than private funds for successful outcomes. The private sector participation project required public-private cooperation. The local economy vitalization project needed public funds to build infrastructure. The local living improvement project needed public funds for infrastructure. The local living network project could be led by public funds including the facility fund. The local economy operation project required public and private funds for local programs and facility support. The results offer the optimization of financial support efficiency by providing customized support funds for neighborhood regeneration projects.

Throughout peach orchards in Greece, plant protection, fertilization and irrigation are often conducted empirically, negatively affecting energy use efficiency and greenhouse gas emissions (GHG emissions). The aim of this study was to apply alternative fertilization and irrigation practices in canning peach orchards to improve nutrient and irrigation water management and to assess yield, energy input–output and the carbon footprint of the alternative cultivation practices for three important clingstone cultivars of different ripening periods. Energy use analysis revealed that the cultivation practice with the highest energy use was almost always irrigation, followed by fertilization, plant protection, weed control and pruning. Electricity, fuels, fertilizers and machinery presented the highest energy requirements. Alternative fertilization, in combination with deficit irrigation (DI), was more energy efficient compared to farmers’ practices in all cultivars based on energy use efficiency, energy productivity and specific energy. Irrigation was the cultivation practice with the highest impact on GHG emissions due to electricity and, secondly, to fuel consumption. Alternative fertilization and DI decreased the intensity (kg CO2eq kg−1) of the emitted GHG compared to farmers’ practices. In conclusion, alternative fertilization and irrigation practices improved energy use efficiency and decreased the carbon footprint of the canning peach orchards by improving yield and decreasing fertilizer and irrigation water input.

Published: July 2022

The goal of this article is to forecast migration flows in Latvia. In comparison with many other countries with sufficiently symmetric emigration and immigration flows, in Latvia, migration flows are very asymmetric: the number of emigrants considerably exceed the number of immigrants. Since statistical data about migration are usually inaccurate, we employ fuzzy time series forecasting methods for prognosticating migration flows in Latvia forecasting. The use of this type of method is often useful not only for forecasting purposes. Three different methods for fuzzy time series forecasting are used. A detailed comparative analysis of the obtained results is given. Generalized forecasts of the expected net migration flow in the future are presented.

Over the years, research on fuzzy clustering algorithms has attracted the attention of many researchers, and they have been applied to various areas, such as image segmentation and data clustering. Various fuzzy clustering algorithms have been put forward based on the initial Fuzzy C-Means clustering (FCM) with Euclidean distance. However, the existing fuzzy clustering approaches ignore two problems. Firstly, clustering algorithms based on Euclidean distance have a high error rate, and are more sensitive to noise and outliers. Secondly, the parameters of the fuzzy clustering algorithms are hard to determine. In practice, they are often determined by the user’s experience, which results in poor performance of the clustering algorithm. Therefore, considering the above deficiencies, this paper proposes a novel fuzzy clustering algorithm by combining the Gaussian kernel function and Grey Wolf Optimizer (GWO), called Kernel-based Picture Fuzzy C-Means clustering with Grey Wolf Optimizer (KPFCM-GWO). In KPFCM-GWO, the Gaussian kernel function is used as a symmetrical measure of distance between data points and cluster centers, and the GWO is utilized to determine the parameter values of PFCM. To verify the validity of KPFCM-GWO, a comparative study was conducted. The experimental results indicate that KPFCM-GWO outperforms other clustering methods, and the improvement of KPFCM-GWO is mainly attributed to the combination of the Gaussian kernel function and the parameter optimization capability of the GWO. What is more, the paper applies KPFCM-GWO to analyzes the value of an airline’s customers, and five levels of customer categories are defined.
‘I Just Want to Go Home’: Emotional Wellbeing Impacts of COVID-19 Restrictions on VFR Travel
Authors: Kelly Catherine
Published: July 2022

The COVID-19 global pandemic has had a profound impact on the taken-for-granted familial connections bound up in VFR travel. This paper examines the emotional impacts on diasporic migrants who could not travel to their homeland for extended periods of time. It considers pre-pandemic VFR patterns and assesses new meanings attributed to post-pandemic renewed travel. The lived experiences, patterns and emotions of seventy mainly UK-based participants were examined in this study. The research approach used both Maslow’s hierarchy of needs analysis and Urry’s tourist-gaze as conceptual frames for assessing these emotional experiences. The research showed that for many diasporas, the need to travel home is central to a sense of personal and place-identity as well as emotional security. The impacts of the pandemic in terms of wellbeing and emotional health were keenly felt by study respondents. Furthermore, contrary to much prior VFR research, this pandemic related study showed that in this instance, it is the “people” of VFR rather than just the “place” (of home) that are most valued. The removal of the right to VFR travel reinforced the centrality of family connections, especially in times of crisis. A mindful, VFR gaze emerges, rooted deeply in Maslow’s basic human needs pillars of safety, love and belonging. This was shown to be a highly tuned post-COVID-19 gaze, where familiar touchstones of home helped to restore depleted emotions through performances and practices of connectivity. The unique global pandemic experience of a world full of migrant mobile diaspora brought to an abrupt halt, emphasizes the need for tourism research to focus on the emotions embedded in the inherent human-place connections of VFR travel. The longitudinal-temporal legacy of COVID-19 on this form of tourism requires future research attention for both the tourism industry and tourists themselves.

Published: July 2022

Unexploded ordnance devices (UXO) pose a potential threat to human life and material during offshore construction activities. Extensive survey activities are conducted to locate, identify, and clear these objects as necessary. For the period thereafter, it is necessary to investigate whether areas that have already been cleared, or even objects that remain in place, may be affected by mobilization under tidal currents or waves, and could thus have an impact on operation and maintenance during the lifetime of the offshore installation. In this study, model simulations based on fluid mechanics are described to derive the loads on the objects caused by currents and waves and combined with knowledge of the known burial condition of the objects. Within the model, the hydrodynamic and hydrostatic loads on the object caused by waves and currents are balanced with inertia and rolling resistance. Thus, the critical current velocity and critical wave conditions for the mobilization of different objects are calculated and compared with the environmental conditions prevailing in the North Sea. As a result, a recurrence interval for the potential mobilization of objects on the seafloor is given, which can now be used to optimize route surveys and thus help accelerate offshore construction work. It is shown that currents are not able to mobilize the objects investigated in the study in almost all regions of the North Sea. Waves can mobilize certain objects in very shallow and extreme conditions.
