Academic literature on the topic 'Boroque mode'

The article discusses the history of the formation of the resort village “Borovoye” in accordance with the Butler’s model. Butler's model itself breaks down the development process of a tourist resort into five separate stages: discovery, growth and development, success, stagnation, renewal. At the first stage, the settlement is explored or discovered by a small number of people. From the sources of those years, it is known that in 1898 in the pine forest surrounding Lake Borovoye, by decree of the tsarist administration, the State Forestry was created to protect forests. In addition, the next decree on the foundation of the health resort followed in 1910, in which patients with pulmonary tuberculosis and other diseases, primarily related to the respiratory system, would be treated. After the establishment of Soviet power and civil confrontation, starting in 1920, the entire area around the settlement of Borovoye was recognized by a decree of the Council of People's Commissars as a resort place that received nationwide significance throughout the RSFSR. Over time, when the uniqueness of the healing air and the diverse flora, as well as the beauty of these places were generally recognized, in 1935 the Borovoye State Reserve was organized. At the stage of growth and development, these places, as a rule, receive a powerful impetus for development, in our case; this is the laying of the railway from Petropavlovsk along the Trans-Siberian Railway in the 20s of the last century and the appearance of a sanatorium in Shchuchinsk. The next phenomenon is the evacuation of scientific institutes and many prominent scientists here during the Great Patriotic War. A new stage in the development of the village began in the 1950s, when the development of virgin and fallow lands began in Northern Kazakhstan. During the period of stagnation and in the difficult nineties, when the republic found itself in a socio-economic crisis, the popularity of the Borovoye resort decreased somewhat, as the income of the population decreased in these years, because of which the initial attractiveness of the resort place weakened. Currently, due to the pandemic, directly related to diseases of the respiratory system, the need for the Borovoye resort has increased dramatically. According to Butler's model, there are two options during the renewal of a tourist resort: to decline, or to rejuvenate and develop more sustainable strategies

Les hydrogels injectables et auto-réparants suscitent un intérêt particulier dans les domaines de l'ingénierie tissulaire et de la médecine régénératrice. En raison de la nature dynamique de leurs réticulations, ces gels peuvent être pré-formés dans des seringues, extrudés sous cisaillement et s’auto-réparer spontanément après arrêt de la déformation mécanique. Au vu du potentiel que peuvent offrir les polymères fonctionnalisés par des acides boroniques pour la fabrication de gels covalents réversibles, nous avons développé des hydrogels injectables d’acide hyaluronique (HA) réticulés par des liaisons esters boronates pour des applications esthétiques et biomédicales. Pour élaborer de tels gels avec des propriétés optimisées, nous avons exploré l’effet de la nature du dérivé d’acide boronique ainsi que du motif saccharidique greffés sur le HA sur les propriétés rhéologiques dynamiques des gels. Parmi les différents dérivés d'acide boronique, le benzoboroxole (BOR) a été choisi en plus de l'acide phénylboronique (PBA) pour complexer différents motifs saccharidiques greffés sur le HA. Comparé au PBA, le dérivé BOR est, en effet, capable de se complexer de manière plus efficace à pH neutre et avec une plus grande variété de composés saccharidiques, en particulier les glycopyranosides. Cette étude a démontré que les propriétés rhéologiques dynamiques des assemblages de HA formés par complexation des unités de BOR ou PBA avec les différents sucres sont étroitement liées à la dynamique des échanges moléculaires et à la thermodynamique des pontages. En outre, nous avons également établi pour la première fois la possibilité d’obtenir des hydrogels de HA auto-réticulants à pH physiologique via des interactions multivalentes entre les unités de BOR greffées sur le HA et des groupements diols se répétant sur la chaîne polysaccharidique. Outre le BOR, la capacité de son homologue cyclique à six chaînons, la benzoxaborine, et d’un nouveau dérivé original similaire à ce composé a été explorée en tant que nouveaux sites de complexation de saccharides pour la formation de réseaux de HA réversibles. Compte-tenu des propriétés injectables, d'auto-réparation et de réponse à différents stimuli démontrées par ces nouveaux hydrogels de HA, ces biomatériaux apparaissent comme des candidats prometteurs pour de nombreuses applications innovantes dans le domaine biomédical, notamment pour l'ingénierie tissulaire et la thérapie cellulaire
Injectable and self-healing hydrogels have recently drawn great attention in the fields of tissue engineering and regenerative medicine. Such gels can be pre-formed into syringes, be extruded under shear stress and show rapid recovery when the applied stress is removed due to the dynamic nature of their crosslinks. Given the exciting potential benefit of using boronic acid-containing polymers to construct dynamic covalent hydrogels, we explored this attractive strategy to design injectable boronate-crosslinked hydrogels based on hyaluronic acid (HA) for aesthetic and other biomedical applications. To design hydrogels with optimized properties, we investigated the effect of the nature of the boronic acid moiety as well as the sugar molecule grafted onto the HA backbone on the gel properties. Among arylboronic acid derivatives, benzoboroxole (BOR) was selected in addition to phenylboronic acid (PBA) as the binding site for sugar moieties grafted on HA. This choice was based on the efficient binding capability of BOR at neutral pH compared to PBA, and on its ability to complex glycopyranosides. With this study, we demonstrated that the dynamic rheological properties of the HA networks based on BOR- or PBA-saccharide complexation are closely linked to the molecular exchange dynamics and thermodynamics of the small molecule crosslinkers. Besides, we also established for the first time the feasibility of self-crosslinking HA hydrogels with extremely slow dynamics at physiological pH through multivalent interactions between BOR derivatives grafted on HA and diols from the polysaccharide chains. Finally, in addition to BOR, we demonstrated the unprecedented capacity of its six-membered ring homologue, benzoxaborin, and a new original benzoxaborin-like derivative as new carbohydrate binding sites for the formation of reversible HA networks. Taking into account the injectable, self-healing and stimuli-responsive properties showed by these new HA hydrogels, these biomaterials appear as promising injectable scaffolds for many innovative applications in the biomedical field, including in tissue engineering and cell therapy

Abstract Industry-wide, the degradation and corrosion of steel infrastructure and the associated maintenance to prevent or mitigate this, poses a heavy environmental and operational burden across many industry segments. To address these challenges, ADNOC Group Technology, led by our Non-Metallic Steering Committee and ADNOC Upstream, in partnership with several selected specialist product companies, is deploying a range of innovative solutions as pilot trials within a holistic R&D program – which is aiming to transform our production and processing facilities, with a close focus on integrity management – and specifically we are assessing the deployment of non-metallic pipelines, storage and process vessels as well as downhole tubing and casing. Focusing specifically on flowlines and pipelines - traditional steel pipes used in the oil patch are burdensome to store, transport and install, as well as susceptible to degradation, corrosion-driven wall loss in challenging operational environments, such as those found Onshore and Offshore Abu Dhabi. This vulnerability results in increased operating risks as facilities mature, adding cost and time for inspection, maintenance and eventually - replacements that will lead to production deferrals or interruptions. A range of non-metallic pipeline technologies are being assessed and piloted in this program, including stand-alone extruded polymeric pipe and liners, Reinforced Thermoplastic Pipe (RTP) used Onshore and Offshore, specialized non-metallic flexible pipelines for Offshore including Thermoplastic Composite Pipe (TCP) and downhole tubulars. The methodology involves placing segments of RTP into live pipeline systems for a finite duration of operation – usually one year – and then removing sections to assess any degradation in performance, or capability of the RTP during that time. These test results will be the subject of a further publication at the end of this trial period. In this paper, we will focus on RTP piloting Onshore and specifically mention a unique trial in an ultra-sour gas field, where the technology has already delivered the required performance: safely transporting gas with levels of H2S up to 10% by volume. This trial also proves that specifically engineered non-metallic products may be successfully operated at the high temperature and high pressure (HPHT) levels that are characteristic of our reservoirs. As a result of this qualification program, ADNOC will see an increase in the longevity of pipeline assets and will enjoy significantly higher reliability and availability, with lower maintenance cost over time. It has been demonstrated that RTP can provide life-cycle savings exceeding 60% when compared to carbon steel pipes [1]. As the polymer feedstock that is used to manufacture these products can be produced regionally, including material supplied in the UAE by Borouge, the manufacturing/use/recycling will close a vital and sustainable full cycle, promoting In-Country Value (ICV) and generating additional economic opportunities in the emerging non-metallic industrial ecosystem for the nation. The multi-faceted value proposition is described in more detail in Figure 1 below. Figure 1 Value and sustainability benefits from increased use of non-metallic materials This is a clear example whereby ADNOC and the UAE continue to demonstrate global leadership by creating and investing in sustainable and energy-efficient technology solutions across the entire value chain while diversifying the national economy.
