FORMATION OF HEALTHY LIFESTYLE OF STUDENTS BY MEANS OF PHYSICAL TRAINING

In today's conditions, the problem of forming a healthy lifestyle among students is particularly relevant. The article analyses the causes, consequences and ways to overcome the problem of healthy lifestyles among young people. The reasons that have a negative impact on the health of young people include a lack of physical activity, bad habits, unhealthy diet, chronic stress, depression or anxiety, lack of sufficient awareness of the importance of a healthy lifestyle. It is emphasised that the promotion of a healthy lifestyle among students is an important strategic task of higher education institutions, which can be successfully solved in various forms of physical improvement. It is noted that physical education is one of the key components of a healthy lifestyle and its proper formation, as it motivates people to strive to live actively, move, do good deeds and be active members of a healthy society. It is important to inform young people about the benefits of a healthy lifestyle and the dangers of unhealthy habits. Healthy lifestyle education should be systematic. It is stated that the formation of a healthy lifestyle should be carried out at three levels: social (information and educational work); infrastructure (specific conditions in the main spheres of life, preventive measures, environmental control); personal (system of human values, standardisation of everyday life). The creation and implementation of special programmes and projects will help young people to maintain a healthy lifestyle.

Isolated and Associated Use of the Nematophagous Fungi Pochonia chlamydosporia and Duddingtonia flagrans to Control Taenia saginata Eggs

The aim of this study was to evaluate the isolated and associated use of the nematophagous fungi Pochonia chlamydosporia (isolate VC4) as an ovicide and Duddingtonia flagrans (isolate AC001) as a predator in the control of Taenia saginata eggs. Viable T. saginata eggs were obtained by dissecting mature proglottids from a specimen. For the experimental assay, four groups were formed in microtubes, as follows: (G1—T. saginata eggs/control); (G2—100 T. saginata eggs + VC4); (G3—100 T. saginata eggs + AC001); (G4—100 T. saginata eggs + VC4 + AC001). All the groups were stored in a B.O.D. incubation chamber at a temperature of 27 °C for 15 days and then the contents of the microtubes were analyzed using an optical microscope with a 40x objective. At the end of the assay the treated groups (G2 to G4) showed ovicidal activity (destruction of eggs) compared to the control group (G1). The highest ovicidal percentage was observed in group G2 (eggs + VC4), with 43.3%. In groups G3 and G4 (combination of fungal isolates), the ovicidal percentages were 25.7% and 25.6%, respectively. The results of this study shed light on a new possibility for the combined use of different species of nematophagous fungi, which could be used in the future for environmental biological control of T. saginata eggs.

Clothing suggestions based on comfort extracted from physiological and emotional parameters

PurposeThe comfort of apparel is not only a feeling of perception but also a tangible measure. The fit and fabric of clothing can exert a perception of comfort for the wearer, whereas actual comfort largely depends on physiological and emotional soothing. However, there is still no solid work on connecting the bridge between physiological and emotional feelings to the comfort of clothing. In this study, we have conceptualized, formulated and proven the relation between physiological and emotional parameters with clothing fit and fabric to find the true comfort of the wearer.Design/methodology/approachA mixed-method research design using physiological and emotional parameters for different fabric and fit combinations were used for this study. The physiological comfort parameters (i.e. heart rate and respiration rate) are extracted from the subjects using gold-standard clinical devices for various fit and fabric combinations. For the emotional response, a survey was conducted for the same subjects wearing all the fit and fabric combinations. Statistical analysis and modeling were performed to obtain the results.FindingsPhysiological indicators such as heart rate are closely linked with user comfort. Due to the limitations in environmental control, the physiological changes obtained did not significantly vary for different fabric and fit combinations of the clothing. However, a significant change in emotional response indicated a definite relationship between different fabric and fit types. Based on the participants’ responses, weather conditions, size of the clothing item, types of fabrics and style also influence the participants’ choice of clothing.Originality/valueThe research was conducted to discover the relation between true comfort (physiological and emotional parameters) and clothing (fit and fabric), which is unique to the field. This study closes the gap and builds up the relationship, which can help introduce clothing comfort to users in the future. The findings of this study help us understand how fabric types (natural or synthetic) and clothing fit types (loose or fitted) can affect physiological and emotional responses, which can provide the consumer with satisfactory clothing with the suitable properties needed.

Electrochemical sensing at the fingertips: Wearable glove-based sensors for detection of 4-nitrophenol, picric acid and diazepam

A wearable glove-based sensor is a portable and practical approach for onsite detection/monitoring of a variety of chemical threats. Herein, we report a flexible and sensitive wearable sensor fabricated on the nitrile glove fingertips by stencil-printing technique. The working electrodes were modified with multiwalled carbon nanotubes (MWCNTs)/poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) for sensitive and real-time analyses of hazardous or chemical treats, as picric acid (PA) explosive, diazepam (DZ) as drug-facilitated crimes and the emerging pollutant 4-nitrophenol (4-NP). The multi-sensing platform towards PA, 4-NP, and DZ offers the ability of in-situ qualitative and quantitative analyses of powder and liquid samples. A simple sampling by touching or swiping the fingertip sensor on the sample or surface under investigation using an ionic hydrogel combined with fast voltammetry measurement provides timely point-of-need analyses. The wearable glove-based sensor uses the square wave voltammetry (SWV) technique and exhibited excellent performance to detect PA, 4-NP, and DZ, resulting in limits of detection (LOD) of 0.24 μM, 0.35 μM, 0.06 μM, respectively, in a wide concentration range (from 0.5 μM to 100 μM). Also, we obtained excellent manufacturing reproducibility with relative standard deviations (RSD) in the range of 3.65%–4.61% using 7 different wearable devices (n = 7) and stability in the range of 4.86%–6.61% using different electrodes stored for 10 days at room temperature (n = 10), demonstrating the excellent sensor-to-sensor reproducibility and stability for reliable in-field measurements. The stretchable sensor presented great mechanical robustness, supporting up to 80 bending or stretching deformation cycles without significant voltammetric changes. Collectively, our wearable glove-based sensor may be employed for analyses of chemical contaminants of concern, such as explosives (PA), drugs (DZ), and emerging pollutants (4-NP), helping in environmental and public safety control.

A porous thiosemicarbazide functionalized covalent organic framework served as sensitive fluorescent sensor for Hg2+

The detection of heavy metal pollution in food and environment is of great significance for environmental pollution control and human health. 1,3,5-Tris(p-formylphenyl)benzene (TFPB) and thiosemicarbazide (TS) were used as building blocks to construct a thiosemicarbazide functionalized covalent organic framework (COF) through Schiff base condensation reaction. Hg2+ ions can significantly enhance the fluorescence of the prepared COF-TFPB-TS, and thus COF-TFPB-TS can be utilized for highly selective and sensitive detection of Hg2+ ions. Moreover, COF-TFPB-TS showed high performance for detecting Hg2+ in fresh fruit juice, mineral water and tap water, which demonstrated its ability to be applied in real sample testing.

Evaluating the Ventilation Performance of Single-Span Plastic Greenhouses with Continuous Screened Side Openings

Natural ventilation is the most cost-effective environmental control method for protected horticulture. To overcome the issues associated with high temperatures in greenhouses, analyzing their ventilation characteristics and maximizing their natural ventilation performance are essential. Therefore, in this study, the natural ventilation performance of arched single-span plastic greenhouses with screened side openings was empirically investigated. Three identical single-span plastic greenhouses were used in this study, each with different side-opening heights. Temperature and wind-speed data were collected, and the ventilation-volume flow rate was calculated considering both buoyancy and wind forces. The natural ventilation performance of the greenhouses was strongly and positively correlated with the ventilation-area ratio and outdoor wind speed. The ventilation rate increased linearly with an increase in the ventilation-area ratio and high outdoor wind speeds. However, the association between ventilation performance and indoor–outdoor temperature differences was not strong. When the ratios of ventilation areas in the greenhouse were changed to 0.08, 0.19, and 0.29, the average indoor–outdoor temperature differences were 14.0, 10.1, and 7.7 °C, respectively, and the ventilation rates were 0.0081, 0.0196, and 0.0315 m3 s−1 m−2, respectively. The proportion of wind in the total ventilation performance was high with a low ratio of ventilation openings and high outdoor wind speeds. However, the proportion of the buoyancy was high, with a high ratio of ventilation openings and a large indoor–outdoor temperature difference. Overall, this study provides foundational insights for optimizing the design and evaluation of ventilation openings in greenhouses, considering the outdoor wind speed.

A Contrast Experiment on the Ventilation Direction towards Human Head in Personalized Environmental Control System (PECS)

A heating, ventilation, and air-conditioning system is designed for the entire space but falls short in meeting diverse individual needs. Therefore, the personalized environmental control system is proposed to address individual thermal requirements and it has been widely accepted and produced to have significant practical value for humans. In order to enhance the comfort level based on the PECS, the impact of the airflow direction towards the head in terms of physiological and psychological sensations was investigated. Different airflow directions were considered as follows: front blowing (FB-PV), side blowing (SB-PV), back blowing (BB-PV), top blowing (TB-PV), and a control group No-PV. A total of 56 participants were invited to assess the thermal environment, and their skin temperature was measured. The results revealed that the airflow towards the head improved thermal comfort and reduced the mean skin temperature by 0.4–0.6 °C, with FB-PV showing particularly promising results. TB-PV demonstrated the highest level of comfort with a score of +1.05 (slightly higher than “Just comfortable (+1)”) and scored significantly higher in overall willingness at +1.21 (higher than “Willing (+1)”). Conversely, FB-PV resulted in a discomfort level due to restricted breathing under the continuous airflow condition.

Observing isolated synaptic vesicle association and fusion ex vivo.

Here, we present a protocol for isolating functionally intact glutamatergic synaptic vesicles from whole-mouse brain tissue and using them in a single-vesicle assay to examine their association and fusion with plasma membrane mimic vesicles. This is a Protocol Extension, building on our previous protocol, which used a purely synthetic system comprised of reconstituted proteins in liposomes. We also describe the generation of a peptide based on the vesicular glutamate transporter, which is essential in the isolation process of glutamatergic synaptic vesicles. This method uses easily accessible reagents to generate fusion-competent glutamatergic synaptic vesicles through immunoisolation. The generation of the vGlut peptide can be accomplished in 6 d, while the isolation of the synaptic vesicles by using the peptide can be accomplished in 2 d, with an additional day to fluorescently label the synaptic vesicles for use in a single-vesicle hybrid fusion assay. The single-vesicle fusion assay can be accomplished in 1 d and can unambiguously delineate synaptic vesicle association, dissociation, Ca2+-independent and Ca2+-dependent fusion modalities. This assay grants control of the synaptic vesicle environment while retaining the complexity of the synaptic vesicles themselves. This protocol can be adapted to studies of other types of synaptic vesicles or, more generally, different secretory or transport vesicles. The workflow described here requires expertise in biochemistry techniques, in particular, protein purification and fluorescence imaging. We assume that the laboratory has protein-purification equipment, including chromatography systems.

The Public Health Leader Who Brought Antisepsis to William Halsted.

William Halsted wrote to aging surgeon, Stephen Smith, in 1919, that he remembered the lessons Smith had taught him, "when I walked with you through the wards of Bellevue Hospital." Smith was an early advocate of Joseph Lister's antiseptic method, and because of his public health work, he was also an early advocate of environmental hygiene and microbial control based on the unproved germ theory. While Lister's work at the time emphasized germ-killing around the operative site with carbolic acid (antisepsis), Smith adopted and encouraged surgical practices at Bellevue that would be hallmarks of the germ-preventing (asepsis) surgical approach that fully developed after German bacteriologic discoveries in the mid-1880s, and with which Halsted is historically identified. Some physicians and historians have emphasized temporal and conceptual differences between Lister's antisepsis and German asepsis, but Smith and Halsted's experiences argue that surgical asepsis was the evolutionary outcome of germ theory-based surgical changes that began well before scientific proof arrived.

Environmental control and metabolic strategies of organic-matter-responsive bacterioplankton in the Weddell Sea (Antarctica).

Heterotrophic microbial communities play a significant role in driving carbon fluxes in marine ecosystems. Despite their importance, these communities remain understudied in remote polar oceans, which are known for their substantial contribution to the biological drawdown of atmospheric carbon dioxide. Our research focused on understanding the environmental factors and genetic makeup of key bacterial players involved in carbon remineralization in the Weddell Sea, including its coastal polynyas. Our experiments demonstrated that the combination of labile organic matter supply and temperature increase synergistically boosted bacterial growth. This suggests that, besides low seawater temperature, carbon limitation also hinders heterotrophic bacterial activity. Through the analysis of metagenome-assembled genomes, we discovered distinct genomic adaptation strategies in Bacteroidia and Gammaproteobacteria, both of which respond to organic matter. Both natural phytoplankton blooms and experimental addition of organic matter favoured Bacteroidia, which possess a large number of gene copies and a wide range of functional membrane transporters, glycoside hydrolases, and aminopeptidases. In contrast, the genomes of organic-matter-responsive Gammaproteobacteria were characterized by high densities of transcriptional regulators and transporters. Our findings suggest that bacterioplankton in the Weddell Sea, which respond to organic matter, employ metabolic strategies similar to those of their counterparts in temperate oceans. These strategies enable efficient growth at extremely low seawater temperatures, provided that organic carbon limitation is alleviated.

Environmental Food Contaminants and Control Recommendations

Environmental contaminants are considered a significant food safety risk. The rising population increased food production and industrialization have accentuated the importance of addressing food contamination. The primary causes of these contaminants in food include agricultural practices, industrial activities, waste management, and air and water pollution. Contamination can occur at various stages of the food chain and can reach consumers. Various strategies and measures are recommended to prevent and control environmental food contaminants. In this regard, appropriate production systems, the improvement of agricultural practices, and the monitoring of food production systems crucial. Governments and international organizations also play a role in establishing and enforcing food safety standards concerning environmental contaminants. In conclusion, this brief review addresses significant environmental contaminants such as heavy metals, dioxins, microplastics, nitrite-nitrate, PCBs, and melamine, and highlights potential health issues. Continuous updating of knowledge and strategies in this field through future research and development is essential.

The impact of host development and density stress on the diversity of microbial communities in the gut and its surrounding environment of the Chinese alligator

AbstractThe Chinese alligator (Alligator sinensis) is currently an endangered species due to a combination of factors, including climate change, anthropogenic activities, and habitat fragmentation. Captivity plays a crucial role in mitigating the decline of the Chinese alligator population. Currently, there is a lack of clarity regarding the influence of host development and captive conditions on the gut microbiota of Chinese alligators. The aim of the study was to investigate the gut bacterial communities of Chinese alligators and their surrounding environmental bacterial communities using 16S rRNA sequencing. The primary gut flora of Chinese alligators consists of Proteobacteria, Bacteroidetes, and Firmicutes. Proteobacteria is the most abundant and efficient settler in the gut, water, and sediment. PCoA and Adonis test revealed significant differences in bacterial communities across these habitats. Venn analysis revealed overlap in OTUs among the gut, water, and sediment, varying with growth stage and density stress. Different growth stages of Chinese alligator guts harbor distinct pathogenic bacteria, requiring attention. Density stress leads to an increase in pathogenic bacteria, a decrease in gut absorption efficiency. PICRUst2 predicts more abundant metabolic pathways related to gut function during high‐density stress, possibly linked to Roseburia. SourceTracker Analysis indicated that water bacteria have a greater impact on Chinese alligator gut bacteria than sediment, and density stress significantly affects the contribution of environmental microorganisms to the gut microbes of Chinese alligator. BugBase analysis identified water body microbes as the main source of “potentially pathogenic” phenotypes in the gut microbiota. RDA analysis found dissolved oxygen (DO) in water to be the most significant factor influencing water microorganisms, positively correlated with certain pathogenic strains. These findings enhance our understanding of the significance of microbial communities in the gut and surrounding aquatic environment of the Chinese alligator. Furthermore, they provide theoretical support for environmental regulation, disease control, and healthy breeding.

State of the art on plasma-liquid route synthesis monometallic Au, bimetallic Au/Ag core–shell and alloy nanoparticles: Toxicological, сanalytical, antimicrobial activity for environmental control

Nanoparticles (Au monometallic, bimetallic structures Au-Ag alloy and Aucore – Agshell) were synthesized in aqueous solutions with traditional capping agent - sodium citrate, using a one-step (for monometalic and alloy structure) and two–step (for Aucore – Agshell NPs) liquid-phase anode type plasma process. The effects of parameters of synthesis: precursors concentration, the solution plasma process discharge time, molar contents Ag+/Au3+ for alloy NPs, and molar content of Ag+ for Au core NP to the characteristics of the synthesized NPs, including average size (the size distribution, polydispersity index), optical absorption properties ect.) were investigated. The synthesized nanoparticles have the following characteristics: Au NPs with λ=530–540 nm and d = 5–60 nm, the monometalic structure; Ag/Au with the λ=410–530 nm and d = 28–80 nm, bimatalic strucrure of alloy; NPs with significant blue-shift the λ=530→410 nm, depending the shell thickness (the thickness of the deposited Ag shells varied from ∼1–15 nm) and d = 21–35 nm for NPs core(Au)–shell(Ag). TEM images clearly confirm the effectiveness of a one- and two-step plasma-liquid treatment for the synthesis of monometallic Au NPs and the two different structures of the NPs (bimetallic structures Au-Ag alloy and Aucore@– Agshell). The effect of nanoparticle structure on antimicrobial and catalytic properties relative to their respective monometallic counterparts was demonstrated. Among the different investigated structure NPs only for bimetallic core−shell structured AucoreAgshell NPs was found strong synergistic effect for antimicrobial and catalytical activity.

Design and Simulation Implementation of Indoor Lighting Integrated Control System Based on Fuzzy Control

Abstract With the improvement of people’s living standards, higher requirements have been put forward for the quality of the living environment. The progress of science and technology has provided the possibility for the further development of intelligent buildings. As an important component of intelligent buildings, the intelligence level of intelligent lighting is relatively fall behind, especially energy-saving and comprehensive linkage are not considered in the scope of intelligent lighting. According to the characteristics of indoor environment control variables and controlled variables, this paper uses fuzzy control method to realize the comprehensive control of indoor lighting, summarizes the corresponding measures taken by experience into control rules, and constructs a controller to control the complex lighting process instead of people. Through the construction of control rules, the natural lighting is constrained under the full consideration of the influence of temperature and ventilation. The purpose of giving priority to the use of natural lighting and taking into account the overall energy optimization of the system is achieved. The energy-saving idea of combining lighting control with other systems of intelligent building is proposed, and the system performance is simulated and analyzed. It has the advantages of high integration, high degree of intelligence, energy saving and convenient use.

Model-based predictive greenhouse parameter control of aquaponic system.

The effectiveness of an aquaponic system significantly relies on the habitat provided for both the fish and plants. As an integral component of aquaponics, hydroponic cultivation benefits greatly from the controlled environment of a greenhouse. Within this environment, factors such as temperature, carbon dioxide levels, humidity, and light can be carefully adjusted to maximize plant growth and development. This precise regulation ensures an ideal growing environment, fostering the flourishing of plants and contributing to the overall success of the aquaponic ecosystem. This study presented a control approach for an aquaponic greenhouse system. It aims to keep the greenhouse climate parameters (temperature, CO2 concentration, and humidity) at their ideal levels. The proposed control strategy is a two-layered mechanism in which the first layer presents an optimization framework using particle swarm optimization (PSO) algorithm to give the setpoints for the controller, and the second layer demonstrates a constrained discrete model predictive control (CDMPC) strategy to maintain the desired trajectories received from the optimization layer. To validate the results obtained using PSO, this study incorporates genetic algorithms (GA) and assesses their performance in comparison. Given similar computational efficiency and low computational time for both algorithms, the optimal values identified by particle swarm optimization (PSO) are adopted as the setpoints. Two performance criteria, relative average deviation (RAD) and mean relative deviation (MRD), are derived to evaluate the tracking performance of the proposed CDMPC controller under external disturbances. A comparison of the proposed CDMPC with the PI controller is also offered. According to the comparison results, our proposed CDMPC performs better than the PI controller with lower RAD values (temperature, 1.1315; CO2 concentration, 0.9225; humidity, 2.547) and MRD values (temperature, 0.315; CO2 concentration, 0.25; humidity: 1.013). The controller is validated to be efficient by its strong control performance, highlighted by robustness, efficient setpoint tracking, and adequate disturbance rejection. This novel approach might prove to be a useful technique for developing environmental control strategies that can be used for potentially boosting production rates of aquaponic greenhouse systems, maximizing profitability, and reducing labor needs. By maintaining optimal conditions, it can enhance ecosystem health, improve yields, and streamline operations, paving the way for greater system performance and sustainability.

Discovering university students’ behaviour to promote distance learning on the DingTalk telecommunication platform during the COVID-19 pandemic

ABSTRACT This research is based on university students’ experience of using DingTalk in distance learning during the COVID-19 pandemic. Although the distance learning mode on the telecommunication platform provides university students with comprehensive functions, they have limited motivation to accept it and even express dissatisfaction with this new learning model. To narrow the research gap, this study establishes a research model based on the COM-B Behaviour Changing theory and the Hofstede cultural theory, and it analyses influencing factors from Environmental opportunity, Personal capability, and Cultural control aspects. Applying the variance-based structural equation modelling and partial least squares path modelling (PLS-SEM), 358 valid questionnaires have been analysed through the SmartPLS. All hypotheses can be supported, such as the relationship between official department support and students’ distance learning motivation, the connection between privacy security awareness and students’ motivation, and the relationship between power distance and students’ motivation. The research findings will be helpful in enhancing the distance learning system, and more and more students will have an opportunity to accept a high-quality distance education during and after the COVID-19 pandemic.

Interrogating Pollutants in Collecting Institutions During the Implementation of HVAC Energy-Saving Strategies: Lessons Learned and Practical Implications for Optimizing Sustainable Environmental Control

ABSTRACT Strategies of outside air reduction, fan speed adjustments, and temporary system shutdowns can be effective ways to maintain or improve the preservation quality of a collection environment while reducing the financial burden and carbon footprint of a collecting institution. However, current criteria guiding safe implementation of energy-saving strategies focus on temperature and RH alone, which ignores risks posed by pollutants. This research aims to address this by monitoring indoor and outdoor-generated pollutants at four collecting institutions before and during implementing energy-saving strategies. Alongside temperature and RH loggers, continuous pollution monitors were located within the mechanical system and collection spaces. Additionally, energy monitors were installed on the mechanical systems serving the collection spaces to quantify the energy consumption prior to and during operation modifications. Initial results indicate pollutant levels remain stable during the test periods, and did not exceed baseline concentrations. In this paper, the lessons learned from this field research are addressed and practical implications for optimizing sustainable environmental controls are given.

Implementasi Program Pengendalian Pencemaran dan Perusakan Lingkungan Hidup di Sungai Batang Arau oleh Dinas Lingkungan Hidup Kota Padang

This study aims to provide an in-depth investigation of implementing the pollution and environmental devastation management program in the Batang Arau River. The investigation is motivated by the significant levels of waste contamination in the Batang Arau River, primarily caused by industrial and home garbage. The contamination of the Batang Arau River leads to floods during the rainy season, adversely affecting public health and severely impacting the fishing industry in Padang City. In addition, the Padang City Government aims to enhance the water quality of the Batang Arau River from level IV to level II to make it suitable for tourism purposes. In order to address this issue, the Padang City Environmental Service has created a program to control pollution and environmental degradation in the Batang Arau River. The research employs Merilee S. Grindle's implementation theory and utilizes a qualitative methodology. The research findings indicate that the execution of the Environmental Pollution and Destruction Control Program in the Batang Arau River by the Padang City Environmental Service is now underway, however it has not yet reached its maximum effectiveness. This is because the program encountered various impediments, including limited funding, insufficient public awareness regarding the preservation of the Batang Arau River's ecology, and the failure to attain the program's primary benefits. Nevertheless, the program's implementation has been executed proficiently.
