Abstract
The implementation of sustainability is a keys concept for many industries. The tourism industry is no exception. Geopark as a conservation area that pays attention to sustainability by utilizing tourism activities as the socio-economic development of the surrounding community still has obstacles in its implementation. The low level of public understanding about the importance of tourism development in the Geopark area is still an obstacle. By using qualitative descriptive analysis methods through literature studies, this study aims to analyze the condition of the community and the role of stakeholders in realizing sustainable tourism. The substantial actor of stakeholders is required as a forum for coordination and communication for the development of tourist areas. It is significant because it determines community participation in the management of Geopark tourism areas.

Abstract
Goat milk kefir has gained popularity as a functional food. Incorporating natural ingredients with functional properties into kefir making could increase the functional properties in the kefir product. Moringa oleifera leaf has been extensively used for traditional medicine due to its multifunctional properties. This study aimed to investigate the chemical properties of goat milk kefir added with moringa leaf powder. The study was conducted in a Completely Randomized Design, using five treatments and five replicates (three replicates for each treatment). The additional levels of moringa leaf powder were 0, 0.5, 1.0, 1.5, and 2.0 % w/w. The result showed that moringa leaf powder added to kefir making has significantly (P<0.05) increased acidity and decreased pH; however, the proximate analysis did not show a significant effect (P>0.05). Incorporating 2% moringa leaf powder could increase acidity by 58.61% and decrease pH by 8.53% compared to control. This study found that 2% moringa leaf added to the kefir making produced that the highest acidity (1.115%) and the lowest pH (5.07). The average compositions of total solids, fat, protein, ash, and carbohydrate in this study were 18,17%, 4.939%, 7.22%, 0.988%, and 5.019%, respectively.

Authors: Zazdravnykh E , Chendev Yu , Smirnova M 
Published: June 2022

Abstract
Agroforestry is an essential tool for improving soil fertility and sustainable land use. We aimed to reveal the role of the old-growth shelterbelt in changing the basic Chernozem properties under the shelterbelt and at 10, 30, and 60 m distance from its edges (the south of the Central Russian Upland, Belgorod region). Our database includes organic carbon content, storage, and group composition, total nitrogen, exchangeable magnesium and calcium, the soil - water extract composition, and pH from different soil layers up to 3m. We detected the increase in humus horizon thickness, soil organic carbon content and storage, total nitrogen, exchangeable magnesium, acidification, and lowering the effervescence line in shelterbelt soil in comparison to arable ones. Agroforestry leads to the soil transformation - the shelterbelt soils differ from arable at subtype taxonomic level, and the influence of shelterbelts on adjacent arable soils can be traced up to 60 meters distant.

Authors: Lopina E 
Published: June 2022

Abstract
The issues of studying the structure of aesthetic and consumer parameters of the environment of settlements located within the boundaries of the emerging and dynamically developing Belgorod agglomeration in the southwestern part of the country are discussed. The specific characteristics of the studied settlements and the reasons for differences in environmental assessments are determined, depending on the geographical location, including the distance from the core of the agglomeration (the city of Belgorod), and the rate of change of integral social, economic and geo-ecological processes and conditions, which is reflected in the selected clusters. The implementation of the principles and methodology for evaluating the aesthetic and consumer parameters of the environment developed by the author made it possible to calculate the coefficients of representation of the particular elements of the environment and the total coefficients for three spatiotemporal forms. The prospectiveness and the necessity of application of the research results in the development of management mechanisms for modern urban ecosystems are shown, aimed at providing and creating favorable living conditions, in accordance with the complex of ecological and aesthetic demands of the population.

Published: June 2022

Abstract
The agro-industrial complex of Russia is developing in difficult socio-economic, political conditions; however, the grain sub-complex demonstrates the sustainable nature of its development, confirming this with an increase in production volumes. The key role in this has been played by the introduced organizational, economic, managerial, and structural changes that adapt the industry to work in new economic conditions and risks. As a result, Russia is a leading player in the global food market. In the agricultural sector of the economy, there are intensive and extensive factors of present and future development. The reorientation of production towards the priority of intensive factors is possible, based on such key areas as technical and technological renewal, modernization, digital transformation of the industry, which will provide it with significant competitive advantages in the face of high global risks. The current trends in the world market, aimed at increasing demand for grain, also cause a change in the structure of production in regions. Changes in the structure of production entail changes in production volumes. Extensive factors of growth in the scale of grain production can be used to a very limited extent, without prejudice to the economy and the regional market for agricultural products. The priority direction for further development of grain production in the region should include intensive production methods. In this case, the structure of agricultural land and sown areas does not undergo significant transformation and global structural changes, and the increase in production volumes is achieved due to the complex of applied intensive methods of agricultural production.

Abstract
Currently, the increase in milk productivity is achieved by using traditional feeds and balancing additives in the diets of cows. The research was carried out in the Altai Krai in the APC "Kirov's Collective Stud Farm" on steppe red breed cows. The purpose of the work was to determine the effect of mineral and vitamin additives on milk productivity; for this purpose, 3 groups of animals were formed. The first group served as the control and received a standard farm ration (SFR), 2nd experimental – SFR and an additive containing vitamins and minerals (VMA) in the amount of 100 g/head per day, 3rd experimental – SFR and an additive containing proteins, vitamins and minerals (PVMA) in the amount of 500 g/head per day. In the course of the research, it was found that providing the SFR with additional PVMA allowed to increase the level of milk yield by 9.3% and by 12.6% in the 3rd experimental group relative to the 2nd and 1st experimental groups. The inclusion of feed additives to the diet had a significant impact on the chemical composition of milk. In the cows of the 3rd experimental group, the maximum butter-fat yielding capacity (4.65%) was noted; it exceeded the values of the 2nd experimental and 1st control groups by an average of 0.10-0.12%. The level of protein and casein in milk was higher in the experimental groups. The highest protein content was observed in the 3-experimental group - 3.28%. The analysis of casein amount indicates that the animals of the 3rd experimental group receiving PVMA reached an indicator value of 2.71%, which was 0.11-0.13% higher than in the 2nd experimental and 1st control groups. Thus, it can be concluded that the use of PVMA in cows' feeding diets provided an increase in milk productivity and improved milk properties.

Abstract
Currently, in the agriculture of the Turkestan region, all agricultural products are obtained as a result of the use and introduction of chemicals and pesticides. Nevertheless, all these chemicals have done more harm than profit, they primarily pollute the soil and the environment with biogenic elements. In recent years, optimal norms of organic and biological fertilizers have not been applied in irrigated lands, based on this, dehumification is progressing in gray-earth soils and leads to soil salinization. In this regard, the question of restoring soil processes arises, and, above all, organic fertility, ensuring an increase in organic matter reserves in the soil and obtaining environmentally friendly cotton products using only organic and biological meliorants. Therefore, scientists-cotton breeders, in conditions of medium-saline gray-earth irrigated soils, conducted scientific research on intensive methods of organic farming technology on cotton plantations in the south of Kazakhstan.

Published: June 2022

Abstract
In order to solve the problems about rapid increasement rate of water cut and large production decline in bottom water heavy oil reservoir due to active bottom water and high crude oil viscosity, the research on CO2 huff-and-puff technology is carried out. The results showed that the mechanism of CO2 huff-and-puff was mainly to reduce the viscosity of heavy crude oil, carbonate reacted with bottom water and formed interlayer to achieve viscosity reduction and precipitation. The comprehensive water cut was decreased by 35%, and the average oil production of a single well was increased by 3∼4 times. Therefore, CO2 huff-and-puff technology was one of technologies about bottom water control and oil production stabilization, and it is of great significance to enhance oil production in heavy oil bottom water reservoirs.

Abstract
Strain is a commonly used tool to tune the optoelectronic properties of semiconductors. It is especially effective for transition metal dichalcogenides (TMDs), which can withstand extreme strain up to 10%. To date, localised strain fields have been applied by transferring TMDs flakes onto a patterned SiO2 substrate. Here, we present a novel approach, where the strain in MoS2 monolayer is induced by an array of homoepitaxially grown GaAs nanomembranes. This represents a first step towards the integration of TMD monolayers with III–V semiconductor nanostructures, which is essential to develop scalable nanophotonic platforms. The strain imposed by the nanomembrane lifts the degeneracy of the exciton states, leading to linearly polarised emission. The principal axis of the linear polarisation of the emission is strictly determined by the orientation of the nanomembranes. This result is fully consistent with the expected broken crystal symmetry resulting from the imposed uniaxial strain.

Abstract
In this study, poly(2-hydroxyethyl methacrylate) [p(HEMA)] based hydrogels responsive to the pH, temperature and magnetic field were synthesized. The surface properties of p(HEMA) were improved by designing the stimuli-responsive hydrogels made of MAGA, NIPAAm and methacrylate-decorated magnetite nanoparticles as a function of pH-, thermo- and magnetic responsive cell culture surfaces. These materials were then modified an abundant extracellular matrix component, type I collagen, which has been considered as a biorecognition element to increase the applicability of hydrogels to cell viability. Based on results from scanning electron microscopy (SEM) and thermal gravimetric analysis (TGA), stimuli-responsive hydrogel demonstrated improved non-porous structures and thermal stability with a high degree of cross-linking. Mechanical analyses of the hydrogels also showed that stimuli-responsive hydrogels are more elastomeric due to the polymeric chains and heterogeneous amorphous segments compared to plain hydrogels. Furthermore, surface modification of hydrogels with collagen provided better biocompatibility, which was confirmed with L929 fibroblast cell adhesion. Produced stimuli-responsive hydrogels modulated cellular viability by changing pH and magnetic field.

Abstract
We demonstrate the generation, 40 km fiber transmission, and homodyne detection of single-mode squeezed states of light at 1550 nm using real-time phase control of a locally generated local oscillator (LO), often called a ‘real LO’ or ‘local LO’. The system was able to stably measure up to around 3.7 dB of noise suppression with a phase noise uncertainty of around 2.5°, using only standard telecom-compatible components and a field-programmable gate array. The compactness, low degree of complexity and efficacy of the implemented scheme makes it a relevant candidate for long distance quantum communication in future photonic quantum networks.
Two routes to hydrogen evolution for a Co-polypyridyl complex with two open sites
Authors: Xue Toro Liqin , Kiriakidi Sofia , Thapper Anders , Ott Sascha , Lundberg Marcus 
Published: June 2022

Abstract
Cobalt polypyridyl complexes efficiently catalyze hydrogen evolution in aqueous media and exhibit high stability under reducing conditions. Their stability and activity can be tuned through electronic and steric considerations, but the rationalization of these effects requires detailed mechanistic understanding. As an example, tetradentate ligands with two non-permanently occupied coordination sites show higher activity with these sites in cis compared to trans configuration. Here reaction mechanisms of the Co-polypyridyl complex [CoII(bpma)Cl2] (bpma = bipyridinylmethyl-pyridinylmethyl-methyl-amine) have been studied using hybrid density-functional theory. This complex has two exchangeable cis sites, and provides a flexible ligand environment with both pyridyl and amine coordination. Two main pathways with low barriers are found. One pathway, which includes both open sites, is hydrogen evolution from a CoII-H intermediate with a water ligand as the proton donor. In the second pathway H–H bond formation occurs between the hydride and the protonated bpma ligand, with one open site acting as a spectator. The two pathways have similar barriers at higher pH, while the latter becomes more dominant at lower pH. The calculations consider a large number of interconnected variables; protonation sites, isomers, spin multiplicities, and the identities of the open binding sites, as well as their combinations, thus exploring many simultaneous dimensions within each pathway. The results highlight the effects of having two open cis-coordination sites and how their relative binding affinities change during the reaction pathway. They also illustrate why CoII-H intermediates are more active than CoIII-H ones, and why pyridyl protonation gives lower reaction barriers than amine protonation.
Trajectories of Compliance With COVID-19 Related Guidelines: Longitudinal Analyses of 50,000 UK Adults
Authors: Wright Liam , Steptoe Andrew , Fancourt Daisy 
Published: June 2022

Abstract

Background
Governments have implemented a range of measures focused on changing citizens’ behaviors to lower the transmission of COVID-19. While international data shows that compliance did decline from the start of the pandemic, average trends could mask considerable heterogeneity in compliance behaviors.

Purpose
To explore trajectories of compliance with COVID-19 guidelines.

Methods
We used longitudinal data on self-reported compliance from 50,851 adults in the COVID-19 Social Study collected across two waves of the pandemic in the UK (April 01, 2020–February 22, 2021). We modeled typical compliance trajectories using latent class growth analysis (LCGA) and used multinomial logistic regression to examine whether individual personality and demographic characteristics were related to compliance trajectories.

Results
We selected a four-class LCGA solution. Most individuals maintained high levels of compliance and reported similar levels of compliance across the first and second waves. Approximately 15% of participants had decreasing levels of compliance across the pandemic, reporting noticeably lower levels of compliance in the second wave. Individuals with declining compliance levels were younger on average, in better physical health, had lower empathy and conscientiousness and greater general willingness to take risks.

Conclusions
While a minority, not all individuals have maintained high compliance across the pandemic. Decreasing compliance is related to several psychological traits. The results suggest that targeting of behavior change messages later in the pandemic may be needed to increase compliance.
Fall prevention in older people: past, present and future
Authors: Close Jacqueline C T , Lord Stephen R 
Published: June 2022

Abstract
Over the past 50 years we have transitioned from accepting falls as an inevitable consequence of ageing to something that can and should be prevented. Numerous studies have elucidated the contributors to falls and how to assess a person’s risk of falling. There are many effective approaches to preventing falls in older people including those with cognitive and physical impairments. Exercise is the most tried and tested approach with good evidence that moderate to high intensity balance training is an effective fall prevention strategy. Other successful single modality interventions include enhanced podiatry, home safety interventions, expedited cataract extraction, cardiac pacing for people with carotid sinus hypersensitivity and vitamin D supplementation in people living in care homes. Multiple interventions (everyone receives the same intervention package) and multifactorial interventions (interventions tailored to identified risk factors) are effective particularly in high-risk populations. In more recent years we have seen the emergence of new technologies such as devices and software programs that can offer low-cost interventions which may be more sustainable than our traditional time- and resource-limited approach to prevention. There is still more to be done and a translational focus is needed to ensure that effective interventions are scaled up and delivered to more people while at the same time maximising adherence and maintaining the fidelity of the interventions.
