Natural Gas Exports Legal Regulation under the Foreign Legislation
Authors: Koshman Sergey S.
Published: October 2023

The study of legal regulation of natural gas export relations in foreign countries and the factors influencing the formation of a particular system of legal regulation of such relations, identification of common approaches and differences in different legal systems constitute an urgent task of energy law. In order to study the different approaches to the regulation of natural gas export, this article examines the legal regulation systems that have been developed in the leading countries exporting this energy resource, such as Norway and the USA, as well as in the countries where the technological and legal framework for natural gas export is being formed, with Argentina as an example. The results of the study show that natural gas export in all the countries considered is subject to the appropriate permit issued by an authorized state body.

The formation of the system of legal regulation of natural gas export is influenced by many economic and legal factors, the most important of which are: level of demand for natural gas in domestic market of an exporting country; existence of international treaties with importers that provide grounds for exemption from customs duties and unhindered export of natural gas; availability of sufficient explored natural gas reserves and technologies of natural gas extraction in an exporting country. The features of natural gas export regulation in foreign legal systems reviewed in this article can be considered when improving natural gas export regulation in the Russian Federation.

Authors: Shestakov Roman Yu.
Published: October 2023

The article is devoted to the legal issues of the introduction of digital platforms and solutions aimed at improving occupational safety at pipeline transportation facilities. The possible criteria determining the priority of using digital solutions to improve the occupational safety of pipeline transportation employees are investigated. Hazard identification, risk assessment and risk management, as well as occupational injuries, are considered as sources of initial information for determining the need for the use of digital solutions for certain professions and positions at pipeline transportation facilities. Identification of hazards and occupational injuries are considered as factors that make it possible to reasonably determine the need and expediency of the primary testing of digital solutions aimed at improving occupational safety. It is worth noting that the existence of injuries in the framework of hazard identification is not the main and only factor in determining the level of risk. Hazard identification is aimed at identifying harmful and dangerous factors of the working environment and the labor process and is performed in order to prevent accidents, occupational diseases, emergencies and incidents. The risk management process consists in the development of measures aimed at eliminating/reducing risks and improving industrial safety. When managing risks, including the introduction of digital platforms and solutions aimed at improving occupational safety, all existing legal requirements regarding the employees’ rights and freedoms must be observed.

The article discusses and analyzes the legal aspects of the introduction of digital platforms and solutions aimed at improving occupational safety, in terms of regulation and sufficiency of the legal and regulatory framework. The work deliverables are of interest to professionals in legal regulation of occupational safety, professionals in industrial safety, as well as for conducting in-process control and special assessment of working conditions at main pipeline transportation facilities.

Network-Level Changes in the Brain Underlie Fear Memory Strength
Authors: Haubrich Josue , Nader Karim
Published: October 2023

The strength of a fear memory significantly influences whether it drives adaptive or maladaptive behavior in the future. Yet, how mild and strong fear memories differ in underlying biology is not well understood. We hypothesized that this distinction may not be exclusively the result of changes within specific brain regions, but rather the outcome of collective changes in connectivity across multiple regions within the neural network. To test this, rats were fear conditioned in protocols of varying intensities to generate mild or strong memories. Neuronal activation driven by recall was measured using c-fos immunohistochemistry in 12 brain regions implicated in fear learning and memory. The interregional coordinated brain activity was computed and graph-based functional networks were generated to compare how mild and strong fear memories differ at the systems level. Our results show that mild fear recall is supported by a well-connected brain network with small-world properties in which the amygdala is well-positioned to be modulated by other regions. In contrast, this connectivity is disrupted in strong fear memories and the amygdala is isolated from other regions. These findings indicate that the neural systems underlying mild and strong fear memories differ, with implications for understanding and treating disorders of fear dysregulation.
Daidzein alleviates osteoporosis by promoting osteogenesis and angiogenesis coupling
Authors: Jia Junjie , He Ruiyi , Yao Zilong , Su Jianwen , Deng Songyun , Chen Kun , Yu Bin
Published: October 2023

Background

Postmenopausal osteoporosis and osteoporosis-related fractures are world-wide serious public health problem. Recent studies demonstrated that inhibiting caveolin-1 leads to osteoclastogenesis suppression and protection against OVX-induced osteoporosis. This study aimed to explore the mechanism of caveolin-1 mediating bone loss and the potential therapeutic target.

Methods

Thirty C57BL/6 female mice were allocated randomly into three groups: sham or bilateral ovariectomy (OVX) surgeries were performed for mice and subsequently daidzein or vehicle was administrated to animals (control, OVX + vehicle and OVX + daidzein). After 8-week administration, femurs were harvested for Micro-CT scan, histological staining including H&E, immunohistochemistry, immunofluorescence, TRAP. Bone marrow endothelial cells (BMECs) were cultured and treated with inhibitors of caveolin-1 (daidzein) or EGFR (erlotinib) and then scratch wound healing and ki67 assays were performed. In addition, cells were harvested for western blot and PCR analysis.

Results

Micro-CT showed inhibiting caveolin-1with daidzein alleviated OVX-induced osteoporosis and osteogenesis suppression. Further investigations revealed H-type vessels in cancellous bone were decreased in OVX-induced mice, which can be alleviated by daidzein. It was subsequently proved that daidzein improved migration and proliferation of BMECs hence improved H-type vessels formation through inhibiting caveolin-1, which suppressed EGFR/AKT/PI3K signaling in BMECs.

Conclusions

This study demonstrated that daidzein alleviates OVX-induced osteoporosis by promoting H-type vessels formation in cancellous bone, which then promotes bone formation. Activating EGFR/AKT/PI3K signaling could be the critical reason.
Phylomitogenomics elucidates the evolution of symbiosis in Thoracotremata (Decapoda: Cryptochiridae, Pinnotheridae, Varunidae)
Authors: Xu Tao , Bravo Henrique , van der Meij Sancia E.T.
Published: October 2023

Background

Thoracotremata belong to the large group of “true” crabs (infraorder Brachyura), and they exhibit a wide range of physiological and morphological adaptations to living in terrestrial, freshwater and marine habitats. Moreover, the clade comprises various symbiotic taxa (Aphanodactylidae, Cryptochiridae, Pinnotheridae, some Varunidae) that are specialised in living with invertebrate hosts, but the evolutionary history of these symbiotic crabs is still partially unresolved.

Methods

Here we assembled and characterised the complete mitochondrial genomes (hereafter mitogenomes) of three gall crab species (Cryptochiridae): Kroppcarcinus siderastreicola, Opecarcinus hypostegus and Troglocarcinus corallicola. A phylogenetic tree of the Thoracotremata was reconstructed using 13 protein-coding genes and two ribosomal RNA genes retrieved from three new gall crab mitogenomes and a further 72 available thoracotreme mitogenomes. Furthermore, we applied a comparative analysis to characterise mitochondrial gene order arrangement, and performed a selection analysis to test for selective pressure of the protein-coding genes in symbiotic Cryptochiridae, Pinnotheridae, and Varunidae (Asthenognathus inaequipes and Tritodynamia horvathi).

Results

The results of the phylogenetic reconstruction confirm the monophyly of Cryptochiridae, which clustered separately from the Pinnotheridae. The latter clustered at the base of the tree with robust branch values. The symbiotic varunids A. inaequipes and T. horvathi clustered together in a clade with free-living Varunidae species, highlighting that symbiosis in the Thoracotremata evolved independently on multiple occasions. Different gene orders were detected in symbionts and free-living species when compared with the ancestral brachyuran gene order. Lastly, the selective pressure analysis detected two positively selected sites in the nad6 gene of Cryptochiridae, but the evidence for positive selection in Pinnotheridae and A. inaequipes and T. horvathi was weak. Adaptive evolution of mitochondrial protein-coding genes is perhaps related to the presumably higher energetic demands of a symbiotic lifestyle.

In the Philippines, the additional two years in Senior High School allow the student to select a specialization depending on ability, interests, and academic capabilities that prepare them for their chosen course in college. However, statistics show that more students shift from their chosen strand in Senior High School when they pursue their undergraduate education. Quantitative research design utilizing the descriptive and comparative approaches determined the degree of influence of factors on non-STEM students shifting to STEM-related courses and identified if there exists a difference when grouped according to demographics. Using snowball sampling, 214 college students from STEM-related college programs who are shiftees from the non-STEM strand in Senior High School were selected as participants. Utilizing mean and standard deviation, results showed that work opportunities is the most dominant influencing factor in the shift of non-STEM students to STEM-related college programs. Further, utilizing the Mann-Whitney U test, the result showed a significant difference in the degree of influence of factors to shifting career choice in terms of school factor when grouped according to sex. Using the Kruskal-Wallis H Test, the result showed no significant difference in the degree of influence of factors to shifting career choice when grouped according to strand in Senior High School. A career awareness seminar in collaboration with the guidance was developed based on the findings of the study.

Published: October 2023

This study investigated the redox reactions of potassium trisoxalatoferrate(III) trihydrate with perchlorate ion in acid  medium. The stoichiometry of the reaction determined by the mole ratio method were observed to be 1:2. The rate of the reaction showed two parallel pathways. The kinetic results showed first order dependence with respect to both oxidant and reductant concentrations and the experimental data are consistent with the rate law:
\(\frac{-d\left[\mathrm{Fe}\left(\mathrm{C}_2 \mathrm{O}_4\right)_3{ }^{{ }^{3-}}\right]}{d t}=\left\{a+b\left[\mathrm{H}^{+}\right]\right\}\left[\mathrm{Fe}\left(\mathrm{C}_2 \mathrm{O}_4\right)_3{ }^{3-}\right]\left[\mathrm{ClO}_4^{-}\right]\)where \(\mathrm{a}=0.07 \mathrm{~s}^{-1}\) and \(\mathrm{b}=0.74 \mathrm{dm}^6 \mathrm{~mol}^{-2}\). The effect of added species (Zn2+, Mg2+ CH3COO-, I-, and NO3-) on the rates of the reaction and other kinetic evidence suggest that the reactions occurred by the outer-sphere mechanism. The findings from the study has established baseline kinetic data for the redox reaction of potassium trisoxalatoferrate(III) trihydrate with ClO4- and plausible mechanisms have also been proposed for the reaction system.

Published: October 2023

Alzheimer's disorder is a devastating neurodegenerative ailment characterized by cognitive decline and reminiscence loss. As the look for powerful treatments continues, researchers have begun investigating the ability of the ketogenic food regimen to manage the signs and symptoms and development of the disease. The ketogenic eating regimen, a low-carbohydrate, high-fat dietary approach, promotes the manufacturing of ketones as an alternative strength supply for the brain. This article affords an overview of the position of the ketogenic weight-reduction plan in Alzheimer's disease and explores its capacity to repair and improve cognitive function in affected people. We discuss the mechanisms behind the ketogenic eating regimen's impact on mind electricity optimization, neuroprotection, insulin sensitivity, and metabolic health. While the ketogenic weight loss program shows promise, its limitations and issues also are discussed, consisting of challenges of adherence and long-term sustainability, ability dietary imbalances, and personal versions. In addition, research is needed to completely apprehend the therapeutic capability of the ketogenic food regimen in Alzheimer's disease and to decide its most fulfilling implementation as part of a comprehensive treatment approach. Alzheimer's disorder (AD) is a progressive neurodegenerative ailment characterized by cognitive decline, memory loss, and impaired everyday functioning. Currently, there's no treatment for the advert, and available remedy options are limited in their efficacy. However, rising proof shows that the ketogenic eating regimen (KD), an excessive-fats, low-carbohydrate dietary technique, may preserve the ability to manage advert or even sell neuronal repair. The metabolic disorder discovered in ad brains, inclusive of decreased glucose metabolism and impaired mitochondrial function, has led researchers to explore opportunities for electricity resources for brain cells. The KD induces a metabolic kingdom called ketosis, where the frame normally relies on ketone our bodies derived from fats as its most important fuel supply. Ketones provide a greater efficient electricity supply to the brain, bypassing the impaired glucose metabolism in advert patients. Research utilizing animal models and early human trials have validated that the KD exerts numerous useful outcomes on advert pathology. Those outcomes include lowering amyloid- beta (Aβ) plaque accumulation, mitigating neuroinflammation, improving mitochondrial characteristics, and promoting the manufacturing of mind-derived neurotrophic component (BDNF), a protein crucial for neuronal increase and survival. Additionally, the KD has been proven to enhance cognitive characteristics and memory in ad sufferers, although further research is wanted to set up its lengthy-term outcomes and protection.

Aim: Evaluate bixafen plus flutriafol when used in various fungicide programs for peanut foliar and soilborne disease control and yield response when using Georgia M-13 and Georgia 09B peanutvarieties. 

Study Design: Randomized complete block.

Place and Duration of Study: Field studies were conducted from 2018 through 2020 in south-central Texas near Yoakum (29.276o N, -97.123o W).

Methodology: Fungicides were applied with a CO2-propellant sprayer. The spray boom was equipped with three D2-23 hollow-cone spray nozzles per row with the middle nozzle centered over each plant in the row and another nozzle located as such to spray on each side of the plant to provide thorough coverage with a spray volume was 187 L ha-1. All studies included a non-treated control and a comparison treatment of chlorothalonil only at 1.26 kg ha-1.  Each plot consisted of four rows spaced 97 cm apart and 7.9 m long.

Results: The primary foliar disease was early leaf spot, caused by Cercospora arachidicola S. Hori.  Bixafen + flutriafol applied twice in a 4 to 5 fungicide spray program in combination with chlorothalonil provided early leaf spot control as good as or better than the standard of chlorothalonil alone or chlorothalonil + azoxystrobin plus benzovindiflupyr.  Fungicide treatments which included  bixafen + flutriafol reduced southern blight caused by Sclerotium rolfsii Sacc. disease incidence up to 85%. The level of soilborne and foliar disease control exhibited with each fungicide program influenced peanut yield response as those programs which provided the best control also produced the highest yield.

Conclusion: These studies show the ability of bixafen plus flutriafol to provide control of foliar and soilborne diseases found in southwest peanut production.
Futbol ve Havacılığı Birleştiren Girişim: Tayyare Kupası

Published: October 2023

Türkiye’de havacılığın kuruluş çalışmalarına 1911 yılında başlanmasına karşılık Türk askeri ve sivil havacılığı Cumhuriyetin kurulmasından sonra büyük bir atılım ve ilerleme içerisine girdi. Bu ilerlemede Türk Hava Kurumunun kurulması sonrası kurum tarafından gerçekleştirilen faaliyetlerin ve başlatılan “Tayyare İanesi” kampanyasının katkısı büyüktür.

Türk Hava Kurumu, gelirlerini artırmanın ve düzenli bir hale getirmeye çalışmasının yanında hemen hemen her alanı havacılık ile birleştirmeye ve Türk havacılığı için bir gelir kaynağına dönüştürmeye çalışmıştır. Türk havacılığına gelir sağlamak için faydalanılmaya çalışılan alanlardan birisi de spor özellikle de futbol oldu.

Türk Hava Kurumunun kuruluşundan itibaren Türk futbol takımları arasında yapılan münferit karşılaşmalar ile gelir elde edilmeye gayret edildi. 1935 yılında başlatılan “Tayyare Turnuvası” ile bu girişim yurt geneline yayılmaya çalışıldı.

Büyük şehirlerdeki dört, küçük şehirlerdeki en güçlü iki takımın katılması ile düzenlenen turnuvada, Türk halkının futbola duyduğu ilgiden faydalanılarak gelir elde edilmeye çalışıldı.

Konunun öznesi durumundaki Türk Hava Kurumu arşivinin tasnif edilmemiş ve araştırmacılara kapalı olması nedeniyle söz konusu turnuvaya ait bilgiler dönemin süreli yayınlarından araştırılarak, Türk futbolunu sayesinde kurulmak istenen etkin ve modern hava gücüne ne kadar bir maddi katkı sağlandığı tespit edilmeye çalışıldı.
POEMA E RITMO EM MESCHONNIC:

Published: October 2023

Neste artigo, apresenta-se um olhar sobre a continuação das ideias de Humboldt (1990 [1836]) acerca de língua, literatura e o caráter das línguas, na poética, mais precisamente na noção de poema e ritmo, de Meschonnic (2007; 2009 [2007]; 2010 [1999]). Para Humboldt (1990 [1836]) as línguas permitem que o espírito da nação se expresse. Com isso, cada língua possui um caráter próprio que é registrado na literatura das nações. Meschonnic (2007; 2009 [2007]; 2010 [1999]) propõe sua poética com base no estudo do ritmo do poema, da linguagem como um contínuo. Busca-se demonstrar como o pensamento não redutor da linguagem humboldtiano está presente na proposta teórica do estudo da linguagem meschonniquiana.

Because the tumor‐draining lymph nodes (TDLNs) microenvironment is commonly immunosuppressive, oncolytic microbe‐induced tumor antigens aren't sufficiently cross‐primed tumor specific T cells through antigen‐presenting cells (e.g., dendritic cells (DCs)) in TDLNs. Herein, this work develops the micro‐to‐nano oncolytic microbial therapeutics based on pyranose oxidase (P2O) overexpressed Escherichia coli (EcP) which are simultaneously encapsulated by PEGylated mannose and low‐concentrated photosensitizer nanoparticles (NPs). Following administration, P2O from this system generates toxic hydrogen peroxide for tumor regression and leads to the release of tumor antigens. The “microscale” EcP is triggered, following exposure to the laser irradiation, to secrete the “nanoscale” bacterial outer membrane vesicles (OMVs). The enhanced TDLNs delivery via OMVs significantly regulates the TDLNs immunomicroenvironment, promoting the maturation of DCs to potentiate tumor antigen‐specific T cells immune response. The micro‐to‐nano oncolytic microbe is leveraged to exert tumor killing and remold TDLNs for initiating potent activation of DCs, providing promising strategies to facilitate microbial cancer vaccination.

Piezoelectric, pyroelectric, and ferroelectric materials are considered unique biomedical materials due to their dielectric crystals and asymmetric centers that allow them to directly convert various primary forms of energy in the environment, such as sunlight, mechanical energy, and thermal energy, into secondary energy, such as electricity and chemical energy. These materials possess exceptional energy conversion ability and excellent catalytic properties, which have led to their widespread usage within biomedical fields. Numerous biomedical applications have demonstrated great potential with these materials, including disease treatment, biosensors, and tissue engineering. For example, piezoelectric materials are used to stimulate cell growth in bone regeneration, while pyroelectric materials are applied in skin cancer detection and imaging. Ferroelectric materials have even found use in neural implants that record and stimulate electrical activity in the brain. This paper reviews the relationship between ferroelectric, piezoelectric, and pyroelectric effects and the fundamental principles of different catalytic reactions. It also highlights the preparation methods of these three materials and the significant progress made in their biomedical applications. The review concludes by presenting key challenges and future prospects for efficient catalysts based on piezoelectric, pyroelectric, and ferroelectric nanomaterials for biomedical applications.

Despite achieving a significant demand, single‐component white light (SCWL) generation from polymeric materials is a fundamental challenge. Moreover, SCWL emission from conjugated microporous polymers (CMPs) is sporadic. So far, all these emissive CMPs are typically constructed by linking electron‐donor and acceptor systems using expensive metal/ligands at higher temperatures and long duration. Herein, a facile metal/ligand‐free approach is developed to access a newly designed, conformationally twisted, electron‐rich, vinylene‐linked dual‐state WL emissive conjugated microporous polymer quantitatively at 25 °C via Horner‐Wadsworth‐Emmons reaction. This CMP emits intense WL in solution and yellow in the solid state, and after blending with polyvinyl alcohol, generates the flexible, intense WL emission in a thin film. Among the incorporated electron‐rich units, suitably oriented triphenylamine acts as a donor and anthracene as an acceptor. Such donor–acceptor units facilitate the polymer emitting in the entire visible region. The solution WL emission [CIE (Commission Internationale de l'Éclairage): 0.29, 0.32] is tuned by adjusting the concentration in dimethyl sulfoxide, and the film state produces a CIE of (0.30, 0.32). Based on the observations, the origin of WL is anticipated from blue‐emissive anthracene and yellow‐emissive triphenylamine cores and the intramolecular charge transfer process. It introduces easy and economical access to SCWL‐emissive CMP for potential device applications.

Ultra‐wide bandgap semiconductors are gaining attention for their promising properties for UV optoelectronics and UV transparent electronics as well as high‐power applications. Among them, La‐doped SrSnO3 exhibits excellent properties both for deep‐UV transparent oxide semiconductors and deep‐UV transparent conducting oxide. Here, the demonstration of thin film transistors (TFTs) with full deep‐UV transparency is reported, including electrodes, gate oxide, and substrate. The lightly La‐doped SrSnO3 for the channel layer is grown on MgO (100) substrates with buffer layers by pulsed laser deposition. TFTs with a metal—insulator–semiconductor structure are fabricated using high‐k perovskite dielectric LaScO3 as the gate oxide. A degenerately La‐doped SrSnO3 is used as the gate, the source, and the drain electrodes to obtain good ohmic contact with the channel layer as well as UV transparency. The resultant device shows a field effect mobility value of ≈24 cm2 V−1 s−1 and an on/off ratio >106. The optical transmittance of the entire device (including the substrate) is found to be >75% at 300 nm in wavelength. Furthermore, the electrical characteristics of the device exhibit excellent stability under visible irradiation. This research highlights the potential of SrSnO3 in advancing the field of UV optoelectronics and UV transparent electronics.

Despite the performance improvement in perovskite solar cells (PSCs) when MXenes are employed as transport layers, device stability studies are still missing. Especially under real outdoor conditions where devices are subjected to the synergy of multiple stressors. In this work, functionalized 2D titanium carbide (Ti3C2) MXene is employed in normal PSC configuration, at the interface between the halide perovskite and the hole transport layer. The functionalization of the Ti3C2 MXene is made utilizing the same organic additive passivating the halide perovskite layer. The functionalizing strategy creates a continuous link between the MXene and the halide perovskite layer. Champion MXene‐based PSCs revealed a ≈22% efficiency, in comparison with the control device showing 20.56%. Stability analyses under ISOS protocols under different conditions (dark, continuous light irradiation and real outdoor analysis) reveal that the enhancement of the PSCs lifespan is always observed when the MXene layer is employed. Analysis under continuous light irradaition (ISOS‐L) reveal an almost 100% retention of the efficiency for the MXene‐modified device, and outdoor testing (ISOS‐O) carried out for > 600 h reveals a T80 of ≈600 h, while the control device degrades completely. To the best of the authors' knowledge, this is the first report of the stability assesment of MXene‐based PSCs carried out under real outdoor (ISOS‐O) conditions.
