Authors: D.N. Sharma  , Ziaullah Shareef  , K.K. Sharma
Published: January 2022

Abstract: The Singareni Collieries Company Limited (SCCL) planned for deepening the Opencast projects from the present depth of 250m to 400m. For successful operation and forecasting of strata behaviour in pre-mining was recognized. In this direction, SCCL had tie-up with CSIRO, Australia to work jointly, with a lead research provider. As part of these studies, to meet the requirement of generating needy data to conduct Numerical Modelling, extensive program was organized to take up different Physico Mechanical Properties (PMP) tests. In light of this, different tests suggested were taken up in SCCL and NIRM laboratories. The data thus generated were analyzed statistically to make use of the same for Numerical Modelling by CSIRO, Australia. The data generated during the course of organizing different tests, are synthesized and discussed in this paper. The paper deals with the methodology evolved in generation of desired soil and Rock Mechanics data to assess the stability of pit slopes, internal dump and OB dumps.
Geoelectrical Survey for Groundwater Potential in Song and Environs NE, Nigeria
Authors: A. Yakubu  , A. Nur
Published: January 2022

Abstract: Seventeen Vertical Electrical soundings (VES) using the Schlumberger configuration with current electrode spacing of AB/2 = 80m were carried out in Song and environs of Adamawa State of Nigeria to study the groundwater potential. Sixteen VES showed a three-layer earth model; while the remaining one has four-layer earth model. The average thickness of the first layer is 2m with a mean resistivity of 75.14Ωm; representing the top soil and clay material. The second layer has an average thickness of 12.09m with a mean resistivity of 50.0Ωm. This layer is unconsolidated and highly weathered/fractured basement. The average resistivity value of the third layer is 5150Ωm and represents the fresh basement. Water samples were collected from Seven Boreholes (BH) and four Hand-Dug wells (HDW). The overall assessment of the sampled water in the area indicates an average pH value of 5.8, mean temperature of 28.96°C, an average turbidity value of 0.453NTU, and with a mean conductivity value of 159.39µs/cm. The water is mostly acidic with a moderate temperature, and turbidity. Total hardness has an average value of 98.78mg/l indicating a moderately soft water quality. All the Hand-Dug wells in the study area have high concentration of Nitrate and total Coliform count of 50.93mg/l to 67.17mg/l and 12cfu/ml to 27cfu/ml respectively. The high value can be attributed to anthropogenic activities such as chemical fertilizer application and indiscriminate dumping of house hold solid waste in the area as well as animals and human faeces. The high concentration of total coliform count was also observed in BH4 because of the shallow depth. Apart from the HDW and BH4 that are of shallow depth, the groundwater is generally good for human as well as industrial and agricultural uses.
Geotechnical Investigations - A Tool for Deciding Mining Method for Chromite Deposits in Odisha State, India
Authors: Santharam A. , Vardhana Rao Kandula Vishnu
Published: January 2022

The Chromite deposits of Sukinda valley, Odisha, India are of strategic importance for the development of ferro-alloy industries. Around 90% of the India’s chromite ore production derived from two important chromite bearing belts, namely the Baula-Nuasahi belt and Sukinda valley ultramafic complex deposit. In terms of rock strength properties, the host rocks and ore body at Baula – Nuasahi chromite belt are hard and compact, with some structural defects such as joints, faults and dykes. After extracting the chromite ore by surface mining up to the economic pit bottom, the remaining reserves were being mined by underground method. In the Sukinda valley chromite deposits, both the wall rocks and ore body are weak, highly weathered. These mines were operated by opencast method. As most of the working mines in Sukinda valley reached their economic pit limit and there is no further scope to extract the ore by opencast mining. Since the chromite ore bodies are having considerable mineable strike length, width, and depth persistence, there is no option except to convert them into underground mines to increase the life of the mines. The chromite ore bodies were proved up to depth of 270m by exploratory drilling. Some major mining companies are planning for underground mining operations, due to constraint of limited space available for waste dumping, working with common lease boundary, slope instability, high volume of stripping ratio. To overcome such problems, the basic step is to conduct the detailed geo-technical investigations to avoid any unexpected consequences during mine development and stoping operations. The geo-technical investigations comprised of geotechnical mapping of existing mined out benches using scan line surveys, geo-technical drilling and logging of cores for the estimation of RQD, structural discontinuities, testing of cores for material properties followed by performing numerical modeling to evolve a suitable stoping method and excavation geometry. The paper deals with the results of the geo-technical investigations carried out for the planning and design of underground mine workings, design of stope parameters based on the geo-mining conditions.

The inconsistency of power supply in Nigeria has been a major stumbling block to the advancement of her economy and as such it is an issue that requires immediate attention. Uninterrupted power supply is critical in so many applications especially in cases like hospital operations or financial transactions. This work was born out of the need to provide a cost effective and locally available way to automate the switching between various power sources. This issue can be addressed by implementing an Automatic transfer switch which automatically switches on a backup generator in the absence of the utility supply and transfers the load to the generator. The automatic transfer switch also switches off the backup generator and connects back to the utility supply when the power comes back. The circuitry consists of time delay integrated circuits and switching relays. The present effort is a prototype design to create an automatic transfer switch that can be used in an average Nigerian household because of its affordability and simplicity of operation.
A Study on the Effect of Solar Fraction on the Environmental Performance of Solar Air-Conditioning by an Adsorption Chiller
Authors: Basrawi F. , Habib K. , Ibrahim H. , Lee G.C.
Published: January 2022

Solar air-conditioning (AC) is a sustainable air-conditioning system but a back-up heater is needed because a solar AC has intermittent output. This study presents the effect of ratio of heat delivered by solar to the total heat delivered to an adsorption chiller (solar fraction) on the environmental performance of a solar AC system. This AC system need covers cooling demand for an office building in Malaysia. Cooling demand of the building was simulated using well-known building energy analysis software, Equest. Flat-plate collectors and an adsorption chiller were the main component of the solar AC system. Flat-plate collecters were simulated using another software, Watsun, and the adsorption chiller was based on the author simulation model that is comparable with other studies. Environmental performance was analyzed by emission ratio of a boiler and power plants. Solar fraction of 0.33, 0.74 and 0.98 were studied. It was found that solar AC by an adsorption chiller can cover the cooling demand of the office building throughout the year. It was also found that a gas fired boiler is a better auxiliary heater than an electric heater because of the direct conversion of heat from fuel. Less emissions is emited at higher SF compared to conventional AC for all cases of back-up heater. A solar AC must has solar fraction higher than 74% to ensure it emits less emissions than a conventional AC system.

Published: January 2022

This paper presents a new approach for designing a Pseudo Derivative Feed Forward (FDFF) controller for the load- frequency control of the interconnected power system comprising Thermal power system and Gas / Diesel power plants. The proposed PDFF controller is designed to improve the dynamic performance of the frequency and tie line power under a sudden load disturbance in an area with the computation of Ancillary Service Requirement Assessment Indices (ASRAI). The PDFF controller is optimized using Flower Pollination Algorithm (FPA) which is based on the quality of pollination process of flowers. The optimized PDFF controller is implemented to bring back the frequency to stable state and the net interchanges to their desired values for each control area in the shortest possible time based on the settling time and peak over shoot concept of control input deviations of each area. Simulation result reveals that the interconnected thermal power system with Gas power plant ensures a better dynamic and steady state performance than that of the system incorporated with Diesel power plant.
Translating perception metaphors: Linguistic, cultural and social implications
Authors: Kalda Anu
Published: January 2022

Explaining the process of translation has become a challenging aim for different research fields. Rather than just relying on the analysis of translated texts, it is vital to analyse the process of translation: what are the reasons behind the translator’s choices and what are the factors that influence the process? This article uses data from three experiments involving a total of 102 participants, who were asked to translate English perception metaphors into Estonian. The empirical results indicate that there are different factors that either hinder or enable translation. Most importantly, context supports the translating of both cross-cultural and culture-specific metaphors. Also, previous translation experience helps participants deal with metaphoric language. Another salient factor was living in an English-speaking country: participants with such experience found it less challenging to translate metaphoric language even if the metaphors were novel. Finally, educational background in translating facilitates the translation of metaphors

Published: February 2022

Relevant components are necessary for high-fidelity simulation, including scripted scenarios, well-trained simulation educators and “actors,” appropriate mannequins, and realistic environments. Moulage can be yet another key element when used properly. In health courses, moulage can be worked on using various themes. One of them worth working on is burn. This is considering that efficient care requires well-trained health professionals. The aim of this paper is to describe the preparation of moulage that represents a realistic, easy-to-perform third-degree burn using easily accessible and inexpensive materials. First, the researchers began with the search for specific literature, followed by the necessary material selection, and defining a model for the simulated burn. The moulage was executed in approximately 60 minutes. The step-by-step technique has been described and photographed, using low-cost, easily accessible materials to allow moulage to be considered and applied more often in the scenarios of various health-related areas. We believe our model can be used in a variety of simulation scenarios, making it relevant to educators and student learning.

Published: January 2022

Introduction: Acute lateral ankle injuries are commonly managed conservatively but when repair is done in grade III injuries in the professional athletic population it is repaired using the Broström surgical procedure. Augmentation of this procedure using suture tape has been reported to improve ankle stability and physical patient outcomes. Method: This is a retrospective study of 30 patients with grade II-III anterior talofibular ligament instability, treated with augmented Broström-Gould suture tape procedure. The patients were followed up a minimum of 14.4 months post-surgery using AOFAS and RAND 36-item Short Form scores. We also evaluated ability and time to return to previous level of activity or sport following surgery and rehabilitation. Results: Overall patients showed excellent results, with an average AOFAS score of 92.7. According to the SF-36 scale patients perceived low levels of pain (80.6) and good physical functioning (88.3), with 86.7% of patients in the study being able to return to their previous level of activity or sport on average 10.94 weeks post surgery. Conclusion: Augmented Broström with suture tape showed excellent AOFAS and favourable RAND SF-36 outcomes in the short term with a good indication of functional outcomes in patients’ ability to return to previous levels of activity or sport.

Published: January 2022

Arsenic (As) pollution, a potential threat for human health, in vegetables is one of the primary sources of As intake by the human body. In the Pot Experiment, the As content, physiological index and antioxidant enzyme activity of radish were determined. The results demonstrated that the order of As concentration in radish tissues was roots > stems > leaves. Organic selenium (Se) can inhibit the absorption of arsenic in radish more effectively than inorganic Se. The application of organic Se and low concentration of selenite (Se(IV)) significantly enhanced the stress resistance of radish for increasing superoxide dismutase and peroxidase activity, increasing soluble protein, chlorophyll and proline content, and reducing malondialdehyde content. In contrast, the high concentration of Se(IV) and selenate (Se(VI)) treatment group demonstrated stress and toxicological effects on radish. This study provides an idea for further research on the remediation mechanism of Se to As toxicity and provides a reference for the adoption of Se fertilizer in agriculture.
Effect of extraction process and storage time on the quality attributes of pomegranate juice of two local pomegranate varieties
Authors: Alkuraieef Amal N. , AlJahani Amani
Published: January 2022

This study investigates the impact of two extraction processes (squeezing the whole fruit and centrifuging the seeds) of pomegranate juice and storage on sweet and sour pomegranate quality attributes. The pH, acidity, and levels of organic acids, sugars and anthocyanin differed in both varieties and changed during the storage period. Fructose and glucose were the primary sugars, and citric acid was the dominant organic acid in the juice of both cultivars. A high level of established anthocyanin content was 15.40, 18.53, 18.03, 16.92, 16,68 and 15.47 mg/L when the storage period was 0, 5, 15, 32, 48 and 72 h, respectively, in the juice of sweet fruits obtained by squeezing the whole fruit. The juice prepared from the sweet fruits by squeezing method outscored, in all sensory quality attributes, the juice prepared by centrifuging process.

Several studies have focused on the performance of roller shades in terms of glare, outdoor vision, daylight availability and energy performance. Currently, other parameters linked to visual amenity, such as chromaticity and colour rendition, are becoming relevant. When solar radiation passes through a window, it changes its spectral composition due to the presence of the solar shading system and the glazing. Against this background, the present study focuses on the spectral transmittance of eleven woven screen fabrics and its influence on the chromaticity and colour rendition. Results show that dark-coloured woven screen shades provide higher correlated colour temperature (CCT) values (range 6470 K - 6479 K) and therefore would produce “cooler” visual environments, while light-coloured woven screen shades provide lower CCT values (range 5210 K - 5644 K) creating “warmer” visual environments. Regarding colour rendering metrics, the light transmitted through all the studied woven shades shows excellent colour rendition. Finally, it is concluded that the combined analysis of optical properties, spectral data and its impact on parameters that determine the quality of lighting in an interior space enables an understanding of woven screens performance, which results in the possibility of taking appropriate decisions when selecting woven shades.
Upgrading mechanical and electrical systems
Authors: Smith James
Published: February 2022

In carrying out maintenance and rehabilitation investigations of three large overseas dams, there was a need to address the issue of providing up-to-date technology against sustainability. The dams were built in the 1970s and used proven technology from that period. As a result of reduced investment, maintenance had been neglected for some time, resulting in much of the dam equipment being relegated from automatic to manual operation; in some cases, relying on operator knowledge and use of ‘work-arounds’. The challenge for the investigation was to return the dam equipment to full functionality and take advantage of developments in technology, while providing a sustainable solution. The balance between a state-of-the-art technical solution that meets accepted international standards and practices, and operational sustainability can be difficult to attain, particularly in developing countries. The experience and knowledge of engineers who design or manage dams can encourage the use of innovative solutions, which may be at odds with the knowledge and training of those maintaining the dam, and availability of spare parts and service support. This paper will discuss how the balance of sustainability, reliability and redundancy affects the choice of design and, through examples, why there may not always be a single solution.
Drivers for discontinuance: a multi-disciplinary approach to feasibility assessment
Authors: Carter Amy Louise
Published: February 2022

The UK dams and reservoirs community is experiencing renewed public attention following the Toddbrook incident of 2019, among several other recent global incidents. In light of this, many undertakers are now seeking to limit their liabilities through a reduction in the capacity of their reservoirs. In such situations, those undertakers have a responsibility to assess the benefit of retaining their reservoirs against a broad range of considerations, and a multi-disciplinary assessment is beneficial in understanding their intrinsic value. This paper discusses the opportunities and challenges of reservoir discontinuance through an overview of some of the numerous – and often conflicting – constraints. Evidence is provided from optioneering workshops, feasibility studies and concept designs delivered by Arcadis for Canal & River Trust and Natural Resources Wales.
The Old Irish Article
Authors: Goldstein David M.
Published: January 2022

Although the Old Irish article in is standardly described as a marker of definiteness, it also co-occurs with indefinite nouns. This phenomenon has long been known in the literature, but thus far even an adequate descriptive account of it has proven elusive. This article advances
two claims about the distribution of in. First, indefinite referents introduced by in become the focal centre of the discourse. Second, in co-occurs with both definite and indefinite noun phrases because it is a signal to the addressee to retrieve or establish a mental
representation of the referent. Although the distribution of in is unusual within Indo-European, it is actually predicted by the reference hierarchy of Dryer (2014). The Old Irish article is thus of particular importance for our understanding of the typology of article systems and referential
marking.
Affrication as the cause of /s/-retraction: Evidence from Manchester English
Authors: Bailey George , Nichols Stephen , Turton Danielle , Baranowski Maciej
Published: January 2022

Retraction of /s/ to a more [ʃ]-like sound is a well-known sound change attested across many varieties of English for /stɹ/ words, e.g. street and strong. Despite recent sociophonetic interest in the variable, there remains disagreement over whether it represents a case of long-distance assimilation to /ɹ/ in these clusters or a two-step process involving local assimilation to an affricate derived from the sequence /tɹ/. In this paper, we investigate Manchester English and apply similar quantitative analysis to two contexts that are comparatively under-researched, but which allow us to tease apart the presence of an affricate and a rhotic: /stj/ as in student, which exhibits similar affrication of the /tj/ cluster in many varieties of British English, and /stʃ/ as in mischief. In an acoustic analysis conducted on a demographically-stratified corpus of over 115 sociolinguistic interviews, we track these three environments of /s/-retraction in apparent time and find that they change in parallel and behave in tandem with respect to the other factors conditioning variation in /s/-retraction. Based on these results, we argue that the triggering mechanisms of retraction are best modelled with direct reference to /t/-affrication and with /ɹ/ playing only an indirect, and not unique, role. Analysis of the whole sibilant space also reveals apparent-time change in the magnitude of the /s/–/ʃ/ contrast itself, highlighting the importance of contextualising this change with respect to the realisation of English sibilants more generally as these may be undergoing independent change.
Peut-on parler d’un théâtre mythologique chinois ?
Authors: MARTIN Éléonore
Published: January 2022

L’existence d’un « théâtre mythologique » chinois comme catégorie spécifique ne semble pas évidente. Les mythes en Chine sont « des récits de divinités (shenhua 神话) » qui racontent non seulement les histoires de dieux d’un panthéon très riche et mouvant, mais aussi celles de personnages historiques divinisés selon les époques. Ces récits ont été principalement diffusés par la littérature orale (contes, spectacles) et par les romans en langue vulgaire. Un théâtre mythologique chinois, en tant que « catégorie », serait alors constitué d’un répertoire ayant pour thématiques les histoires et légendes des multiples divinités chinoises avec un lien sous-jacent aux croyances religieuses. Mais peut-on distinguer un répertoire mythologique spécifique par ses thématiques, sa dramaturgie et son jeu ?
L’expression française « théâtre chinois » est très ambiguë puisqu’elle peut désigner, pour les novices, à la fois les pratiques traditionnelles, codifiées et chantées (en chinois xiqu戏曲) et les pratiques qui s’appuient sur le modèle européen de « théâtre », en chinois huaju 话剧littéralement « théâtre parlé ». Je me concentrerai sur les xiqu, terme généralement traduit par « opéra chinois ». Ce choix nous permettra d’aborder deux types de contexte de xiqu : un contexte de divertissement joué dans les salles de théâtre et un autre contexte attaché aux fêtes de temple. Les xiqu recouvrent une grande variété de spectacles (plus d’une centaine) qui partagent des codes esthétiques communs tout en ayant leur spécificité. Nous procèderons par coup de sonde dans le vaste corpus des pièces qui peuvent ou qui pourraient appartenir à un « théâtre mythologique ». Nous mettrons ainsi en avant les tendances majeures dans certains styles, par exemple : le Jingju 京剧 (ou Opéra de Beijing), le Yuju 豫剧 (ou Opéra du Henan), etc.
Il s’agira dans cette communication de proposer une mise en contexte des relations entre les notions de mythe, spectacle et religions en Chine puis de proposer un premier état des lieux de la question.
La Résistance à l’épreuve du Lager
Authors: GRASSI Andrea
Published: January 2022

Imaginant retracer les derniers moments d’un groupe de prisonniers politiques slovaques dans un camp d’extermination, Antigone et les autres (1961) de Peter Karvaš s’articule pour bien d’aspects comme une sorte de prolongement des réflexions du dramaturge slovaque autour de la période tourmentée de la guerre. D’emblée, il est évident que le recours à Antigone – symbole par antonomase de la rébellion à un pouvoir tyran –, ainsi que la présence de ces « autres » qui l’aident enfin à réaliser la sépulture de Polly (Polynice, chez Sophocle), soient des éléments dramatiques situant la pièce de Karvaš dans un cadre politique assez proche de celui du socialisme. Mais justement, puisque que le dramaturge slovaque, pour raconter la Résistance, s’appuie sur la médiation figurative du Lager – c’est-à-dire d’une situation-limite qui empêche a priori toute issue tragique et cathartique –, Antigone et les autres se présente en même temps comme quelque chose d’autre, quelque chose de nouveau. Et d’ailleurs, l’interprétation, le sens du texte de Karvaš surgit d’autant plus dans l’écart psychologique entre ses personnages et ceux de la lettre originelle sophocléenne : alors même que, pour l’Antigone du dramaturge athénien, la mort remplissait un destin que l’héroïne elle-même, en le reconnaissant comme propre, embrassait sans aucun compromis, les résistants de Karvaš semblent au contraire, plongés dans le Lager, hésiter constamment sur leurs actions : ils sont moins courageux et héroïques dans la mesure où, malgré leurs idéaux politiques, ils semblent craindre la mort plus qu’autre chose.
Śiva ou le fabuleux spectacle
Authors: MARGNAC Géraldine nalini
Published: January 2022

Mettant en scène les héroïnes, héros et divinités de récits fabuleux transmis oralement, le bharata-nāṭyam peut être considéré comme une forme de théâtre mythologique. Or la notion de « théâtre » dans le domaine indien correspond plutôt au nāṭya, qui recouvre aussi bien le domaine du « théâtre » que celui de la « danse » et cherche à produire le rasa, « saveur » ressentie par les spectateurs. Quant à l’adjectif « mythologique », il s’apparenterait aux kathā, terme sanskrit désignant les « histoires ou récits » ou aux kaṭṭukkatai, terme tamoul signifiant « légendes, contes fabuleux ».
Dans l’extrait du poème que nous souhaitons étudier, il est question de Śiva, figure divine du danseur et de la destruction dans l’hindouisme. Quelle dimension du spectacle implique une telle référence ? Comment le mythe est-il repris dans la création poétique et scénique ? Quel est le rôle du rasa dans la résurgence du mythe ? Quatre propositions scéniques nous amèneront à interroger les enjeux linguistiques et esthétiques d’un mythe présents dans le texte littéraire et réactivé dans un art de la scène comme le bharata-nāṭyam.

La dramaturgie du mythe dans La guerre des femmes : de la découverte de la femme par l’homme à la formation de la société humaine
Authors: COULIBALY Fétigué
Published: January 2022

L’Afrique a connu deux grandes générations. Pendant que la première, particulièrement conformiste, écrit le théâtre conformément au paradigme dramaturgique occidental, la seconde, quant à elle, se définit en s’opposant. Elle est anticonformiste et privilégie les questions relatives à l’authenticité, l’identité, l’affirmation de la personnalité et l’épanouissement du génie créateur africain. Bottey Zadi Zaourou, un dramaturge de cette deuxième génération, manifeste sa révolution dramaturgique par un retour aux sources africaines ancestrales. Ce ressourcement consiste, en réalité, en l’adaptation au théâtre et l’actualisation des mythes et légendes. Autrement dit, il en fait la toile de fond principale de sa fiction théâtrale. À travers cette théâtralisation, il informe, forme et instruit le lecteur-spectateur. En témoigne sa pièce, La guerre des femmes.
Les enjeux thérapeutiques du mythe dans le théâtre de Jerzy Grotowski
Authors: PELAGALLI Paola
Published: January 2022

Au cours de la période du « théâtre de représentation » Jerzy Grotowski propose des spectacles à double effet thérapeutique : ce théâtre qu’il définit capable d’être une « psychothérapie sociale » génère des conséquences bénéfiques aussi bien pour le spectateur que pour l’acteur. Le moyen en est la représentation sur la scène d’une « mythologie commune », c’est-à-dire de thématiques censées toucher autant le groupe des acteurs que le groupe des spectateurs et de les unir dans un lien empathique qui serait la condition nécessaire pour une sorte de catharsis collective. Ces thématiques communément partagées qui doivent être véhiculées par la pièce sont à puiser dans trois grands réservoirs : l’inconscient collectif, l’héritage socio-culturel de la Pologne du XXe siècle et la mythologie chrétienne porteuse de l’image du « héros-christ » – modèle de l’individu qui sacrifie sa liberté pour le salut de la collectivité, très chère à l’histoire travaillée du peuple polonais. Suivant la pensée que la lecture de Carl Gustav Jung lui a proposée, Grotowski affirme que le même parcours souhaité par Jung pour le patient dans son analyse se reproduit au théâtre : de ce fait, le « sujet mythique » représenté sur la scène est reconnu par le spectateur comme une partie de soi ; l’extériorisation sur la scène d’un sujet mythique appartenant à son inconscient l’induit à identifier son individualité comme partie d’une structure collective plus ample. L’individu est ainsi poussé à se détacher des structures de pensées collectives et héritées pour reconnaître sa propre individualité et atteindre ce que pour Jung est le but du parcours analytique : l’individuation. Grâce à la représentation autant le spectateur que l’acteur exercent une catharsis des sujets mythiques intériorisés. Tel qu’au sein du parcours analytique, le but de la performance théâtrale devient alors la découverte d’une identité individuelle nettoyée des images collectivement partagées et des stéréotypes acquis par l’héritage socio-culturel, composantes psychiques qui n’appartiennent pas vraiment à l’individu.
Mythe initiatique Selk’nam

Published: January 2022

The protolytic equilibrium of the excited states of fluorescein depends not only on the equilibrium in the ground state, but also on the efficiency of photoexcitation, relaxation and proton transfer in the excited state. Due to the competing rate of radiative and nonradiative processes occurring in a mixture of protolytic forms, there is still a problem of identifying the fluorescent characteristics of individual forms of fluorescein. In this work, the stationary distribution of the concentrations of the ground and excited states of the cation, a number of tautomers of the neutral form, monoanion and dianion of fluorescein under continuous photoexcitation was simulated. The pH values of the predominant existence of excited states of individual protolytic forms were determined, which were confirmed by steady-state fluorescence measurements. Possible reasons for the discrepancies in the published data on the fluorescent properties of individual protolytic forms of fluorescein are discussed, refined data on the spectral shape and lifetimes of the quinoid and monoanion of fluorescein are obtained.

KA-14 LIDAR, developed at National Aviation Academy of Azerbaijan with the financial support of State Oil Company of Azerbaijan Republic (SOCAR), have been used for detection of distinguishing characteristics of fluorescence spectra of crude oil spills on the surface of Caspian sea and the earth surface of Absheron peninsula. These spills may take place as a result of oil leakage from different Oil-Gas-Production Companies of Azerbaijann (there are totally 8 Oil-Gas-Production Companies belonging to AzNeft and 4 Joint Ventures). Emission spectra of crude oils at present work have been excited by 3d harmonic of Nd:YAG laser (l = 355 nm, d = 5 mm, f = 20 Hz; E = 60 mJ and t = 7 ns). Analysis of fluorescence emission spectra of crude oils taken from 12 Companies revealed distinguishing characteristics of these spectra, main of which included: shape of the spectra, spectral positions of maximum in emission spectra, existence of different fine structures (weak and strong “shoulders”) on short-, as well as long parts of spectra, intensity of emitted bands. Obtained results were useful for creation of data bank of fluorescence spectra of crude oil extracted on the earth of the Absheron peninsula of Azerbaijan as well as from water areas of the Caspian sea.

Nanomaterials based on titanium dioxide are of considerable interest as promising photocatalysts for water and air purification and hydrogen generation. To increase the efficiency of TiO2, it is necessary to expand the spectral range of absorption to the visible region. In this work, the nanocolloids of dark titanium dioxide which was initially prepared by pulsed laser ablation (Nd:YAG laser, 1064 nm, 7 ns) in water were subjected to additional laser irradiation with the same source. Colloidal solutions were dried and TiO2 powders were annealed. A comparative analysis of the optical properties of materials prepared with and without extra irradiation by the methods of diffuse reflection spectroscopy, fluorescence, and Raman spectroscopy has been carried out. The optical band gap of the materials was estimated, and the nature of defect states responsible for intense absorption in the visible region of the spectrum was determined.

Investigates the influence of the conditions and parameters of the synthesis of nitride coatings on their properties, formed by low-pressure discharges in gas-metal beam-plasma formations. The effect of an increased concentration of a gas-metal plasma, the mode (stationary and pulse-periodic) of an arc discharge burning with a cathode spot and the effect of cooling conditions from the target cathode on the number of microdroplets in the TiN coatings on tool steel substrates was studied. The number of microdroplets in the coating is reduced by at least two times when depositing in a pulsed-periodic cathodic-arc discharge and when assisted by an additional gas plasma.

The surface alloying of MA-2 magnesium alloy with aluminum was carried out by the method of combined electron-ion-plasma exposure, which consists in deposition of a thin (1 μm) film of aluminum from an arc discharge plasma and subsequent pulsed electron-beam processing of the "film/substrate" system. The optimal modes of surface Al-Mg alloy formation by the method of electron-ion-plasma exposure were revealed as a result of temperature measurements carried out on the surface of the specimens during irradiation with a pulsed electron beam and depends on energy density and pulse duration. It is shown that the combined surface treatment in optimal modes makes it possible to increase microhardness of the alloyed layer by up to 1.7 times due to alloying of the magnesium alloy surface with aluminum and formation of particles of Mg17Al12 intermetallic phase.

Presents the results of an analysis of our and literature data devoted to the study of the effect of a homogeneous dielectric medium on the rate constant of the radiative transition 1Dg in singlet oxygen. It is shown that the influence of the refractive index n on the radiative rate constant is due to a change in both the density of photon states and the local field factor. At the same time, in a dielectric medium, the transition dipole moment increases significantly as a result of the contact of singlet oxygen with solvent molecules. Only taking into account all of the above factors will provide a consistent explanation of the influence of the medium on the rate constant of the luminescence of singlet oxygen.

A review of studies on the structures of exotic nano-, meso- and microdiamonds with dodecahedral and icosahedral symmetry (N/MDPS) is presented. The unique, complex atomic and electronic structure of N/MDPS, due to its high dodecahedral or icosahedral symmetry, leads to promising transport and mechanical properties that are very promising for photonic, quantum and nanomechanical applications. To explain the nature of diamonds, theoretical models were proposed based on the formation of twinned structures consisting of 5 and 20 symmetrically equivalent tetrahedral and prismatic fragments of a face-centered cubic lattice with the formation of star-shaped and icosahedral clusters. It was shown that these twinned nano- and meso-diamonds are limited in size due to the accumulation of uncompensated structural stresses arising from the deviation of angles from the ideal 72º between diamond <111> facets in tetrahedral fragments of a face-centered cubic lattice, up to 70.5º between five symmetrically equivalent twinned fragments.
