THE EFFECT OF BALLISTIC EXERCISES USING RUBBER BANDS ON DEVELOPING SPECIAL ENDURANCE AND ACHIEVING 400M PERFORMANCE FOR ATHLETES UNDER 19 YEARS OLD

The speed events are exciting activities that have specific physical requirements to achieve performance and outstanding results and compete internationally. This is particularly important in individual sports, especially for youth categories in athletics. The 400m event is considered one of the most challenging sprint events due to the special physical capabilities required to achieve performance. This race demands a huge amount of speed, endurance, and strength, in addition to the requirements of willpower, determination, and perseverance. Achieving the highest levels in this race necessitates a high level of important fitness components and characteristics. Training for this group of runners focuses on speed endurance and strength endurance through ballistic exercises using rubber bands, which help develop the working muscles of the athletes and enhance their physical capacity, subsequently improving performance. Ballistic exercises with rubber bands are considered modern training methods in athletics, aiming to develop muscular strength through strength training. This type of training forces the athlete's body to recruit and stimulate fast muscle fibers, which is crucial because fast muscle fibers have the potential for growth and development in strength training. The importance of this research lies in using ballistic training with rubber bands to develop special capacities and its impact on performance.

HALOPHILIC ASPERGILLUS SPECIES IN EXTREME ENVIRONMENTS: PHYSIOLOGY, ADAPTATIONS, AND APPLICATIONS

Salt is essential for growth at certain limits, but life dwelling in harsh, salty environments are the halophiles. Studies on the halophilic bacteria, archaea, and fungi are reported around different locations, but the fungus Aspergillus species is a predominant halophilic eukaryote reported in various research works. They have been reported from an environment with high salt concentrations. Halophilic Aspergillus species grow better in harsh conditions and have an exciting opportunity for research and application ahead of them. Their potential in biotechnology, together with their special capacity for adaptation to harsh settings, makes them precious in many sectors from environmental science, to biotechnology, and even in bioremediation settings. Therefore, this work review the physiology and unique adaptations of halophilic Aspergillus species in extreme environments, biomolecule produces and their applications in different areas and future prospects.

Synthesis and Evaluation of High-Temperature Resistant Polymer Plugging Agent for Water-Based Drilling Fluids.

As the exploration and development of deep wells have emerged as a key option to extract more oil and gas resources trapped underneath, high-temperature formations impose stringent requirements on the thermal stability of plugging agents used in water-based drilling fluids. In this work, β-cyclodextrin, with its unique conical toroidal rigid stable structure and internal hydrophobic and external hydrophilic special adsorption capacity, was first grafted with maleic anhydride to prepare a silicone polymer and then copolymerized with dimethyldiallylammonium chloride (DMDAAC) in the presence of coupling agent vinyltriethoxysilane (A151) and cross-linking divinylbenzene (DVD) to finally obtain a high-temperature resistant plugging agent (AMMD). Subsequently, the molecular structure was evidenced and the performance of AMMD was examined in the polysulfonate-base fluid via a series of tests including high-temperature high-pressure filtration loss, sand tray plugging, and drilling fluid displacement, and the results were compared with the counterpart Soltex under the same conditions. The optimal synthesis conditions for the plugging agent were found as total monomer concentration of 25%, initiator mass fraction of 1% (based on the mass of monomers), monomer feed ratio of m (DVD):m(A151):m(DMDAAC):m(MD) of 15:3:2:15, pH value of 10, reaction temperature of 75 °C, and reaction time of 4 h. FT-IR spectra indicated that the monomers used to prepare AMMD were successfully involved in the reaction for the design of the plugging agent structure. TGA showed that AMMD has a total weight loss of about 35.98% in the range of 284 to 453 °C. Moreover, the addition of 3%AMMD into the base fluid produced a 4.38-fold and 3.8-fold filtration loss control over 60 min at 200 °C using 400 and 800 mD sand trays, respectively, which were comparatively higher than the commercially available Soltex (ca. 3.72-fold and 3.14-fold, respectively, using 400 and 800 mD). This then contributed to AMMD's superior plugging performance in drilling fluid based on the drilling fluid displacement experiment, implying that AMMD could find potential use as a plugging agent in polysulfonate drilling fluid under severe geothermal conditions.

SPECIAL LEGAL CAPACITY OF LAWYERS: LAWYER, NOTARY AND EXECUTOR

The research object of this paper is the special legal capacity of lawyers, specifically, the special legal capacity for the performance of advocacy activities, regulated by the Law of Advocacy, the special legal capacity for providing notarial services, according to the Law on notaries, and the special legal capacity of the executors, according to the Law on Enforcement. Full legal capacity is the abstract possibility of physical and legal persons to be the provider of rights and obligations. All physical persons have full legal capacity, however, some physical persons, because they fulfill special properties, acquire special legal capacity. The research in this paper has two mail purposes. The first intention is to analyze two assumptions necessary for achieving the special legal skills: 1. professional technical conditions requirements that must be completed by the natural person to operate the professional activities and 2. providing the authorization by the government. The second goal is to show the specifics of the three types of professional activities, notion, acquire, cease and termination. The project will analyze more closely the termination of the special legal capacity because of the loss of one from the two-expectations necessary for its acquisition (obtaining a lawyer's license, terminating the notary or the executor).

A novel model of autologous tooth transplantation for the study of nerve recruitment

BackgroundLimited treatment options exist for damaged nerves and despite impressive advances in tissue engineering, scientists and clinicians have yet to fully replicate nerve development and recruitment. Innervation is a critical feature for normal organ function. While most organs are innervated prior to birth, a rare example of postnatal nerve recruitment occurs in the natural development of secondary teeth during adolescence. Many animals undergo postnatal shedding of deciduous teeth with development and eruption of secondary teeth, a process requiring recruitment of nerve and vasculature to each tooth pulp for viability. Here, the investigators created a novel model for the study of postnatal innervation by exploiting the natural phenomenon of tooth-driven nerve recruitment.MethodsThe investigators theorized that developing teeth possess a special capacity to induce innervation which could be harnessed in a clinical setting for nerve regeneration, and hyptothesized that a transplant model could be created to capture this phenomenon. In this descriptive study, a rat model of autologous tooth transplantation and de novo nerve recruitment was developed by surgically transferring whole developing molars to the autologous tibia.ResultsDownstream histological analysis performed 6 to 14 weeks after surgery demonstrated integration of molar into tibia in 81% of postoperative rats, with progressive pulpal expression of nerve marker ß-tubulin III suggestive of neuronal recruitment.ConclusionsThese findings provide a novel model for the study of organ transplantation and support the theory that developing dental tissues may retain nerve-inductive properties postnatally.

Staging Conscience

Through an in-depth analysis of Johannes Nomsz’s play Iemant en Niemant (1768), this article explores how the seemingly anachronistic genre of zinnespel (morality play) could serve to negotiate key issues of eighteenth-century aesthetical discourse. The combination of abstract ideas and sensual images ingrained into this genre made it an ideal vehicle with which to approach one of the primary problems of the period, namely the mediation between reason and the senses. Nomsz’s play deals with this rationalist/empiricist divide concerning the moral philosophical question of whether reason or feelings guide human ethical behaviour. Through empathy with the allegorical character of Nobody, Nomsz draws his audience into the teeth of a moral dilemma through emotion rather than teaching them a moral lesson. At the same time, he connects moral sentiments to a rational procedure of moral self-judgement by staging conscience as an inner court. I call this way of applying the late medieval genre of morality play to the key questions of eighteenth-century aesthetics and philosophy ‘Enlightened zinnespel’. Turning to the zinnespel with its special capacity to merge mind and senses indicates that at this time, the role of art changed. Art was no longer seen as a medium of knowledge transference, but as a medium that could generate knowledge in a unique way because of its ability to combine cognitive, affective, and sensual dimensions.

Особливості правового статусу банків як юридичних осіб

The article describes the peculiarities of banks’ legal personality and considers approaches to the universal and special legal capacity of banks as legal entities. It also argues the expediency of using the dynamic theory for determining banks’ legal capacity and the application of special legal ability of banks. The analysis provided in the article is based on the approach according to which the legal ability of legal entities that in the future must obtain permission (permit, license, registration or authorization) for the right to conduct certain types of activities arises in two stages. First, a legal entity receives a minimum universal civil legal ability from the moment of its state registration to the extent necessary for its functioning as a legal entity. The second stage is obtaining a banking license by a bank, which is actually obtaining a special legal capacity. The article analyses all banks’ services (banking services, other financial services, as well as non-financial services provided by the banks), the provision of which requires a special legal capacity. It is argued that special legal ability of the bank provides for the ability to have rights and bear responsibilities necessary for the provision of banking services. A banking service on raising funds and refundable investment metals, in contrast to such raising by other financial institutions, should be considered raising to a bank account. Banking services on opening bank accounts provides for a unique feature of banks - their systemic technological nature to ensure monetary settlements between banks and bank clients. It is suggested to introduce in the legislation the provision that not only the opening of bank accounts should be considered a banking service, but also the provision of settlements between parties which have bank accounts. It is argued that the bank is a unique universal financial institution not so much because of the list of services itself, most of which can be provided by other financial institutions, but because it can provide these services in combination with other services (in complex way). It is indicated that the peculiarity of the legal capacity of the bank as a legal entity lies in introducing a two-tier governance system only with a collegial executive body and tighter requirements in regard to the quality of academic and professional background of members of such governing bodies.

Role of nutraceuticals in viral infections as immunomodulators: A comprehensive review

AbstractNutraceuticals are dietary supplements produced from food sources that are intended to improve health through immune system modulation or by helping to prevent and treat a variety of ailments. Their anti‐inflammatory, immunomodulatory, and antioxidant qualities are well recognized. In certain instances, they even show direct microbiological efficacy against viral infections. Because of their special capacity, they may be able to help slow the spread and effects of very infectious illnesses, such as pandemics like COVID‐19. Nutraceuticals work well against viral infections because of a number of intricate processes. Reducing the harm that infections do to the immune system is one of the main effects. Nutraceuticals have the power to stimulate and activate the immune system, improving the body's capacity to identify and eliminate infections. Additionally, they are essential in reducing oxidative damage, which can result in serious consequences and is frequently intensified during viral infections. Nutraceuticals also strengthen immunity by promoting regulatory T cell differentiation and proliferation, which is crucial for preserving immune system homeostasis and limiting hyperinflammatory reactions. They control the production of proinflammatory cytokines, which helps to avoid cytokine storms during viral infections that may seriously harm tissue. This regulation lowers the danger of hyperinflammation and enhances overall results by supporting a balanced immune response. Through a number of biochemical mechanisms, nutraceuticals can strengthen the body's defenses against viral infections. They promote a more effective and efficient immune response by regulating immune cell activities, oxidative stress reduction, and antioxidant pathway activation. Furthermore, by interacting with different cellular signaling pathways, nutraceuticals can affect the synthesis and function of important immune components. This study clarifies the molecular processes behind the immunomodulatory effects of nutraceuticals, highlighting their crucial role in both treating and preventing viral infections.

Zinc oxide nanoparticles: A comprehensive review on its synthesis, anticancer and drug delivery applications

Zinc oxide nanoparticles (ZnONPs), are becoming a more useful tool in a number of fields, including electronics, food packaging, optics, and most significantly, medicinal applications. These nanoparticles show a special capacity to target cancer cells specifically, dissolving into Zn2+ ions in an acidic environment. This leads to the generation of reactive oxygen species that specifically induce cytotoxic effects in malignant cells. Furthermore, ZnONPs work well as carriers to deliver certain anticancer medications straight into tumour cells. Growing interest in ZnONPs has prompted the creation of a variety of production methods, including chemical, physical, and environmentally benign biological approaches. This review explores the biomedical uses of ZnONPs and their production techniques, with an emphasis on the anticancer properties of the compounds. Detailed investigations into the mechanisms by which ZnONPs combat various cancers, influenced by their size, shape, and surface properties, are discussed. Additionally, their role in enhancing cancer treatment through the combined use of chemotherapy and photodynamic therapy, triggered by exposure to ultraviolet (UV) or near-infrared (NIR) light, is examined. The paper further explores the drug delivery capabilities of ZnONPs, including drug loading, stimulus-responsive controlled release, and therapeutic advantages. Finally, the future prospects of ZnONPs research and applications are considered, highlighting potential advancements and innovations

Protective Layers to Improve the Durability of Lithium Anode

Lithium metal anode possesses the advantages of high theoretic special capacity (3860 mAh g-1), low redox potential (-3.04 V vs. S.H.E.) and abundant lithium source. Therefore, tremendous efforts have been paid to explore the remedies of practical utilization. Its applications were seriously hindered by the severely side reactions between the electrolyte solvents and Li metal due to the mismatched energy-gap and large volumetric variation of lithium deposition layer. To address this challenge, various strategies were developed in whole world to prolong the operational life of lithium metal anode.Our group focused on the development of Li+ filtrated membrane to isolate the fresh Li metal from the solvents. Firstly, we established the transplantable LiF-rich membrane via NiF2 film during formation to significantly improve the durability of lithium metal anode.[1] Then, we prepared a Li-filtrated film via a homemade stacked grapheme (SG), which possesses the higher Li nucleation over-potential than that on rational nano-structured copper scaffold (NCS-SG).[2] Additionally, an advanced SEI-functional membrane derived from LiF decorated SG were proposed to protect lithium anode by retarding electron transfer via C-Fx to avoid lithium deposition on the film surface.[3] Finally, the approaches on compatible electrolytes would be proposed.[4-5] In summary, the durability of lithium metal anode could be significantly prolonged by the appropriate protective strategies.

Mitigating the capacity fading of silicon nanoparticles through double carbon coatings and cobalt doping

Silicon (Si) is considered a highly promising anode material for lithium-ion batteries (LIBs), attributing to its suitable working potential and high specific capacity. Nevertheless, the enormous volume expansion during the lithiation, poor electron conductivity, and low lithium-ion (Li+) diffusion rate limit the application of Si anodes. Here, we design a novel single carbon layer and carbon nanotubes (CNT) coated Si nanoparticle (Si NP@C@CNT composites), in which the single carbon layer derived from citric acid separates between Si nanoparticle (Si NP), effectively avoiding the aggregation of Si NP, while the external carbon framework (CF) composed of CNT boosts the electrical contact between Si NP. Such micro-morphology structure can reduce the stresses during lithiation and promote the formation of stable solid electrolyte interface. Besides, the metallic cobalt (Co) and CNT can effectively enhance electrode conductivity and promote rapid electron transfer. The electrochemical testing results indicate that Si NP@C@CNT anode presents faster electrochemical reaction kinetics with excellent cycle stability (1055.1 mAh g−1 after 300 cycles at 0.5 A g−1) and rate performance (809.9 mAh g−1 at 5 A g-1). The special capacities and capacity retention of Si NP@C@CNT composites are 885.3 mAh g−1 and 85.9% after 1000 cycles at 1 A g−1. In addition, the constructed full-cell NCM811// Si NP@C@CNT shows well reversible capacity. This research provides a novel idea for Si -based anode with excellent cycling stability, high electron transfer and fast Li+ diffusion ability for LIBs.

Improving rate performance of FeC2O4/rGO composites on lithium storage via single-polymerization‐induced electrostatic self‐assembly

Based on the wide interlayer distance for ions diffusion, iron (II) oxalate exhibits excellent lithium storage ability. However, the local deposition of metallic nanoparticles of Fe0 leads to low electrochemical reactivity, which hinders the actual application of FeC2O4 in large current regions (>5C). To solve this problem, a strong cationic polymeric electrolyte, polyelectrolyte diallyl dimethyl ammonium (PDDA), was introduced to construct a [FeC2O4(PDDA)]+ ligand. By single-polymerization‐induced electrostatic self-assembly, the [FeC2O4(PDDA)]+ ligand was combined with the surface-charged rGO to produce a FeC2O4/rGO material. It is proved that the rGO carrier improves the interparticle conductivity, electrochemical activity and structure stability of the iron (II) oxalate particles, ensuring the stability of Li || FeC2O4/rGO battery at a rapid charging rate of 20C (8 A g−1) for more than 500 cycles (with the special capacity of 713 mAh g−1). Compared with FeC2O4 electrode, owning to high reactivity of rGO and continuously activating on the nanoscale Fe metal generated at ∼0.75 V, FeC2O4/rGO shows higher electrochemical activity of conversion reaction in the first 50 cycles and better reversibility in the rate charge–discharge test (the capacity rapidly increased to 1158.8 mAh g−1 after 20C cycles). This work reveals how the structural design of conducting and supporting the carrier can achieve fast charging for iron (II) oxalate lithium-ion batteries.

This thorough knowledge seeks to further the current discussion in pharmaceutical research, encouraging creativity and opening the door for the creation of safer, more effective drug delivery systems.

Theoretical and Experimental Approaches to Study of Biological Objects by Mathematical Methods Using the Example of Hormone Production in the Thyroid Gland

The study of any biological object is a complex process that involves a number of successive stages, one of which tools can be a specially created expert system. It is advisable to present the conclusion about the studied biological object in clear forms of expression – quantitative or binary, which are the results of the practical application of the principles of absorption by some researched factors of others, a compromise between them or the prevailing alternative of the studied properties. The involvement of mathematical technologies in the identification and explanation of the regularities of the activity of biological objects requires the display of the results of their research using a mathematical language. This makes it possible to establish regularities in the course of biological processes and predict their consequences. Since any living system is formed from a large number of elements, the organism has a complex hierarchy of structural and functional levels of organization. A mandatory prerequisite for the activity of a biological system is a variety of states, each of them being characterized by its own characteristics – markers of change, which, according to the degree of completeness of the one state transformation into another, should be divided into markers of primary changes, markers of prevailing majority changes, and markers of final changes. Comprehensive application of the Semi-quantitative analysis of electronograms according to Ryabukha O. (2000) and her method for determining the profiles of hormonopoietic cells’ special capacities (2003) when studying the cytophysiology of the thyroid gland in normal and pathological conditions, it is possible to determine the specific link of the follicular cell’s specialized activity, in which there was a violation of hormonopoiesis, and to assess its intensity. The developed Conceptual apparatus of functional connections between organelles of hormone-producing cells when studying them by the Method of correlation analysis by creating intra- and intersystem correlation portraits reflects the features of mutual influences and interdependencies, which deepens the understanding of the intimate mechanisms of hormonopoiesis.

Enhancing Intrusion Detection Systems with Recurrent Neural Networks in D23 Deep Learning

Strong cybersecurity safeguards are increasingly necessary as the digital landscape changes to protect sensitive data and vital infrastructure. To detect and reduce any risks to network security, intrusion detection systems, or IDS, are essential. To improve the precision and effectiveness of anomaly detection, this paper suggests a novel method of intrusion detection that makes use of recurrent neural networks (RNNs). Standard intrusion detection systems (IDS) frequently depend on static rule-based systems, which may find it difficult to adjust to changing and dynamic cyber threats. On the other hand, sequence-retention neural networks, or RNNs, they have a special capacity to recognize patterns and temporal connections in sequential input. Traditional IDS methods are contrasted with the suggested system, which is assessed using common datasets. The RNN-based IDS is successful at detecting known and unknown threats while reducing false positives, according to preliminary data.

Completion of Service in the Israel Defense Forces as a Volunteer with Autism vs Other Psychiatric Disorders: A Survival Analysis

Military service in the Israel Defense Forces (IDF) is compulsory. As part of the conscription process, individuals undergo a thorough occupational evaluation, which may include advanced psychiatric testing. As a result, some individuals are excluded based on presentations of psychiatric diagnoses, such as autism spectrum disorder (ASD), but they can volunteer with the IDF in special capacities (psychiatric volunteers). This study aimed to examine completion rates and correlates of psychiatric volunteers during the first year of service. We used historical data maintained by the IDF to identify psychiatric volunteers (N = 1,159, 76.9% male, M[SD] age = 19.65[0.94]). Overall, 32.3% (n = 374) of psychiatric volunteers had a diagnosis of ASD and 67.7% (n = 785) had other psychiatric diagnoses. We used survival analysis. Overall, 59.5% (n = 690) of the sample completed their first year of volunteering. Non-ASD compared with ASD psychiatric diagnoses (OR = 2.057) was at greater risk to dropout in the first year. Individuals with ASD are more likely to stay in the military as part of volunteer service than individuals with other psychiatric disorders. Individuals with ASD may meaningfully benefit from – and contribute to – military service.

A model of the organizational resilience of hospitals in emergencies and disasters

BackgroundIn the health system, hospitals are intricate establishments that offer vital medical services. Their resilience plays a crucial role in mitigating the societal repercussions of disasters. A hospital must possess the capacity to withstand risks, preserve its fundamental structure and operations, and enhance its preparedness by augmenting various capabilities and promptly recovering from the impacts of potential risks. It enables the hospital to attain a heightened level of readiness. Therefore, this study aimed to develop a resilience model tailored for hospitals to navigate crises and disasters effectively.MethodsThis mixed-method study was conducted in 2023 in three phases: (1) Identification of the factors influencing the organizational resilience of the hospital, (2) Evaluation of the influential factors by an expert panel. (3) Following the standardization process, we administered 371 questionnaires to individuals, such as university staff managers and supervisors, nursing managers, and research unit managers. The sample size was determined by multiplying the components by 10, resulting in 360 (10 * 36). Therefore, we selected a sample size of 371 participants. Structural Equation Modeling (SEM) was employed to examine the causal relationships between variables. These steps were performed using SPSS 25.0 and AMOS 22 software. Finally, we identified and presented the final model. We utilized AMOS 22 and applied the SEM to assess the correlation between the variables, with a significance level of 0.05.ResultsFindings indicate that the appropriate modeling identified five dimensions comprising 36 components. These dimensions include vulnerability, preparedness, support management, responsiveness and adaptability, and recovery after the disaster. The model demonstrates a good fit, as indicated by the X2/d indices with a value of 2.202, a goodness of fit index (GFI) of 0.832, a root mean square error of estimation (RMSEA) of 0.057, an adjusted comparative fit index (CFI) of 0.931, and a smoothed fit index (NFI) of 0.901.ConclusionEnhancing hospital resilience is crucial for effective preparedness and response to accidents and disasters. Developing a localized tool for measuring resilience can help identify vulnerabilities, ensure service continuity, and inform rehabilitation programs. The proposed model is a suitable framework for assessing hospital resilience. Key factors include human resource scarcity, hospital specialization, and trauma center capacity. Hospitals should prioritize efficient resource allocation, information technology infrastructure, in-service training, waste management, and a proactive organizational framework to build resilience. By adopting this approach, hospitals can better respond to crises and disasters, ultimately reducing casualties and improving overall preparedness.

Evaluating the response modification factor (R) for reinforced concrete and steel structures equipped with TADAS devices designed for high seismic hazard in Colombia

Colombia is a country with high seismic activity due to its location at the convergence of the Nazca and South American tectonic plates, making structural safety a key priority in the design, construction, and retrofit of buildings. Currently, one of the most used seismic resistance systems are moment-resisting frames, due to their easy construction and good behavior under vertical loads, however, they are susceptible to structural damage when subjected to moderate to high-intensity earthquakes, which makes the use of seismic protection systems an adequate alternative to prevent damage during seismic events. The Colombian seismic design code NSR-10 proposes a design methodology using a linear structure that represents a non-linear behavior of the building when the expected design earthquake occurs through the response modification factor R. However, the NSR-10 seismic design code does not contemplate the response modification factor for structures with seismic protection systems. Therefore, in this research, a design procedure was configured for buildings with moment-resisting frames of reinforced concrete and steel equipped with TADAS (triangular-plate added damping and stiffness) dampers. The procedure evaluated the developed response modification factor of structures located in high seismic hazard areas in Colombia and considered regular buildings with varying numbers of stories and special energy dissipation capacity. The capacity of the structures was evaluated through nonlinear static analysis using the Pushover method in SAP2000 software. Finally, the response modification factors were calculated for regular buildings with moment-resisting frames and different numbers of stories.
