Published: April 2021

Among the patients who for the first time called on MLEC for the evaluation of disablement group due to locomotor system pathology the patients with coxarthrosis were 35%. The results of clinical, X-ray, radionuclide examination as well as dynamics of medical social rehabilitation (by the data of capacity for work expertise) were analyzed in 200 patients with posttraumatic, idiopathic and dysplastic coxarthrosis. It was shown that existent methods of conservative and operative treatment gave efficient medical rehabilitation only in low percentage of cases, but the absense of clear medical social rehabilitation programme for those patients aggravated the matter. The best results were noted in patients operated for aseptic necrosis of the femur head. In all three forms of coxarthrosis the most efficient method of surgery was total replacement.

Authors: Seinyan S. G. , Aivazyan V. P. , Khanamiryan T. V.
Published: April 2021

One hundred six patients with benign tumors and tumor-like bone pathology underwent surgical treatment. Depending upon clinical pattern of pathologic process, tumor structure, its location, spreading degree, as well as with account of the tendency of one or the other tumor type to recurrence, different resections (marginal, parietal, segmental) were performed. For the replacement of defects, the alloplasty with demineralized bone grafts was used, in some cases it was associated with extrafocal osteosynthesis. In follow-up period (from 2 to 13 years) none of patients (106) had developed metastases. One hundred two patients did not show orthopaedic pathology, 4 patients had minor deformities and manifestations of deforming arthrosis with moderate disturbance of neighbouring joint function. The conclusion was made about the efficacy and perspectiveness of this method.

Authors: Samoshkin I. B.
Published: April 2021

The method of total arthroplasty in dogs with hip joint dysplasia is suggested. The surgery includes 4 steps: resection of femur head, arthroxysis of acetabulum, implantation of artificial ligament and myoplasty of joint capsula. Resection degeneratively changed femur head excludes its fallacious insertion into acetabulum, arrests the pain syndrome. Implantation of artificial ligament as well as myoplasty of joint capsula prevents the instability development and external rotation in joint of distal segments of the extremity that could not be achieved by resection plasty.

Comparison and Analysis of Publicly Available Bathymetry Models in the East Adriatic Sea
Authors:   Hydrographic Institute of the Republic of Croatia, Hydrographic department, Vrdoljak Ljerka
Published: April 2021

In this paper the latest versions of six publicly available bathymetry models: DTU10bat, EMODnet 2018, ETOPO1, GEBCO 2020, Smith and Sandwell V20.1 and SRTM15+ V.2.1. are compared and evaluated in the area of continental shelf of Croatia settled along well intended east Adriatic coast. Survey data in the area is not available through open access data bases, but publicly accessible in agreement with data holders (hydrographic institute, research centres and industry). These grids provide alternative sources of information about seafloor topography. Marine researchers should be acquainted with the main characteristics as well as pros and cons of bathymetry models in order to choose the best one for a specific purpose. In this paper the most important characteristics and information about grids are presented: resolution, coverage, release date, horizontal and vertical datum, data source, registration method, producer and link to website with an emphasis on the underlying source data. The underlying source data is one of the most important parameters that determine the quality of the bathymetric model. Hypsometry curve that is describing the area distribution of depth is calculated for each bathymetry model over the test area of the east Adriatic. For pixel to pixel comparison, grids were resampled to same one-minute resolution and absolute differences between models are calculated in identical points. Absolute differences between models show level of mutual compatibility between models as well as areas of highest disagreements that indicate the presence of outliers or systematic errors within models. In order to demonstrate how well publicly available bathymetry models fit the true topography of the sea floor, grids were compared to high-resolution digital bathymetry model interpolated from the multibeam survey in the area of Murter Sea. This paper should assist in the choice of a most suited bathymetry grid in future maritime studies in the Adriatic.
Th e Possibility of the Inert Gas Generator Environmental Operation Mode Utilization on Long Range 2 Oil Tankers During Discharge Operation
Authors:   OSM Bergen, Milković Marko , Krmek Ivica , Kristić Miho , Sirotić Miljen
Published: April 2021

Long Range 2 tankers are the largest ships used for the transportation of petroleum products. Although more than 400 Long Range 2 tankers are navigating the world’s sea, many of the terminals, at which these ships discharge their cargo, do not utilize their discharging capacity to the full extent. This is due to the technological obsolescence of the terminal and the fact that these terminals are primarily designed to accommodate smaller tankers, such as Medium Range and Long Range 1 tankers. The reduced discharge capacity leads to longer ship stay in the port and increased air pollution due to the release of inert gas into the atmosphere since terminals unnecessarily insist on the continuous operation of the inert gas generator. This paper explains a possible solution to this problem by using environmentally friendly START/STOP operation mode of an inert gas generator using methods of analysis and synthesis, comparative methods and elements of the mathematical method. Environmentally friendly operation mode requires minimal modification of the software program and it is very easy to perform. This mode has a positive effect on reducing overall gas emissions and significant fuel savings.

Erkeklerde spermatogenezin normal şekilde gerçekleşebilmesi için testislerin karın boşluğu dışında, vücuttan 2-3°C düşük sıcaklıkta skrotum adı verilen kese içerisine inmeleri gerekmektedir. Testis iniş mekanizması türler arasında farklılık göstermekle birlikte, testislerin intrabdominal seviyeden skrotuma inmeleri hormonal ve mekanik etkilere bağlı olarak transabdominal ve inguinoskrotal evreler sonunda gerçekleşmektedir. Kranial süspansör ligament dejenerasyonu ve gubernakular şişme reaksiyonu ile karakterize olan transabdominal evre Leydig hücrelerinden salınan INSL3 (İnsülin benzeri faktör-3) kontrolündedir. Testislerin inguinal kanaldan geçerek skrotuma indiği son evre olan inguinoskrotal evre ise androjen bağımlıdır. Testislerin iniş süreci INSL3 ve androjenler dışında, Sertoli hücrelerinden salınan MIS (Mülleryan inhibe edici madde), genitofemoral sinir uçlarından salınan CGRP (Kalsitonin gen-bağımlı peptid), peritoneal bir divertikül olan vaginal prosses, meme hattı altındaki MFP (Meme yağ yastıkçığı) ile Hox genlerinin rol oynadığı kompleks bir süreçtir. Testis iniş mekanizmasında meydana gelen herhangi bir aksaklık durumunda, infertilite ve testiküler kanser nedenleri arasında sayılan anorşi, refraktil testis, kriptorşidizm ve ektopik testis görülebilmektedir.
O posicionamento de Curros Enríquez perante a lingua
Authors: López Varela Elisardo
Published: April 2021

Tras unha breve caracterización social e lingüística do idioma galego na fin do século XIX, coa distinción entre o uso escrito literario e o oral e coa aparición de tratados teóricos gramaticais, este artigo céntrase na posición de Curros Enríquez en favor do galego, tanto a nivel ideolóxico como (socio)lingüístico. A preocupación do celanovés polo galego ficou patente tanto nalgúns dos seus poemas como noutros textos cal a recensión que fixo ao libro El Idioma Gallego de Antonio de la Iglesia. Así, con base na lingua falada polo pobo e mais coas eivas nos estudos gramaticais e na carencia dunha tradición literaria moderna, Curros tratou de elaborar unha lingua literaria e de prestixio, tendo vontade de superar a fase do dialectalismo do Rexurdimento e tratando de conseguir a fixación dun galego literario común.

Published: April 2021

A Collins–Read-féle Felnőtt Kötődési Skála (Adult Attachment Scale, AAS) megbízhatóságának és pszichometriai jellemzőinek vizsgálatát tűztük ki vizsgálatunk céljául. Az AAS-t nemzetközileg széleskörűen használják a felnőtt kötődés jellemzőinek vizsgálatára, azonban érvényességét magyar populáción még nem vizsgálták. Az önkitöltős kérdőív folytonos változóként vizsgálja a kötődési jellemzőket: az eredeti hármas (közelség, függőség, szorongás) és az alternatív kettes (szorongás és elkerülés) felosztás szerint. A pszichometriai mérést 508 fős populáción végeztük, melyben depressziós anamnézisű személyek (n = 264, medián életkor = 25,7 év) és azok nem depressziós testvérei (n = 244, medián életkor = 24,0 év) szerepeltek. A kérdőív belső megbízhatósága a közelség, szorongás és az elkerülés dimenziók esetében elfogadható tartományba esett (Cronbach-α > 0,7), a függőségskála kevéssé bizonyult konzisztensnek (Cronbach-α = 0,62). A kitöltést 14 hónap után ismételve, a teszt-reteszt reliabilitás a teszt minden skáláján megfelelő volt (0,73 és 0,78 között változott). A depressziós és nem depressziós csoport a kérdőív közelség és szorongás dimenzióiban szignifikánsan különbözött egymástól (p < 0,01). Feltáró és megerősítő faktoranalízissel vizsgálva a skála közelség és szorongás dimenziói különültek el egymástól, a függőségskála itemei szórtan helyezkedtek el, a háromfaktoros elgondolás nem nyert megerősítést. Az AAS közelség- és szorongásskálája alkalmazható a kötődési jellemzők vizsgálatára, azonban a kérdőív háromdimenziós struktúrája nem megerősíthető. Eredményeink rámutatnak arra is, hogy a kötődési jellemzők felnőttkorban összefüggést mutatnak a depressziós epizódokkal.

Published: April 2021

Rapid changes of stroke management in recent years facilitate the need for accurate and easy-to-use screening methods for early detection of large vessel occlusion (LVO) in acute ischemic stroke (AIS). Our aim was to evaluate the ability of various stroke scales to discriminate an LVO in AIS. We have performed a cross-sectional, observational study based on a registry of consecutive patients with first ever AIS admitted up to 4.5 hours after symptom onset to a comprehensive stroke centre. The diagnostic capability of 14 stroke scales were investigated using receiver operating characteristic (ROC) analysis. Area under the curve (AUC) values of NIHSS, modified NIHSS, shortened NIHSS-EMS, sNIHSS-8, sNIHSS-5 and Rapid Arterial Occlusion Evaluation (RACE) scales were among the highest (>0.800 respectively). A total of 6 scales had cut-off values providing at least 80% specificity and 50% sensitivity, and 5 scales had cut-off values with at least 70% specificity and 75% sensitivity. Certain stroke scales may be suitable for discriminating an LVO in AIS. The NIHSS and modified NIHSS are primarily suitable for use in hospital settings. However, sNIHSS-EMS, sNIHSS-8, sNIHSS-5, RACE and 3-Item Stroke Scale (3I-SS) are easier to perform and interpret, hence their use may be more advantageous in the prehospital setting. Prospective (prehospital) validation of these scales could be the scope of future studies.

Authors: Çakar Nafiye Emel , Önal Hasan
Published: April 2021

Niemann-Pick type C is a rare lysosomal storage disease caused by impaired intracellular cholesterol transport. The autosomal recessive disease is caused by mutations in NPC1 or NPC2 genes. Clinical-laboratory features, genotype-phenotype correlation and miglustat treatment response of our patients diagnosed with early infantile Niemann-Pick type C were evaluated. In this article, four Niemann-Pick type C patients diagnosed in the early infantile period are presented. Common features of our patients were hepatomegaly, splenomegaly, cholestasis and retardation in motor development. Patients 1 and 2 are twins, with homozygous mutation c.2776G>A p.(Ala926Thr) in NPC1 gene and severe lung involvement. Lung involvement, which is mostly associated with NPC2 gene mutation in the literature, was severe in our patients and they died early. In patients 3 and 4, there were respectively c.2972del p.(Gln991Argfs*6) mutation in NPC1 gene and c.133C>T p.(Gln45*) homozygous mutation in NPC2 gene. In these two patients, improvement in neurological findings were observed with treatment of miglustat. In our twin patients, severe lung involvement was observed. Two of our four early infantile Niemann-Pick type C patients exhibited neurological gains with miglustat treatment.

Published: April 2021

In view of the fact that a single sentiment classification model may be unstable in classification, this paper attempts to propose a joint neural network and ensemble learning sentiment analysis method. After data preprocessing such as word segmentation on the text, combined with document vectorization method for feature extraction, we then use four basic classifiers including long short-term memory network, convolutional neural network, a serial model combining convolutional neural network and long short-term memory network, and support vector machine to train model, respectively. Finally, the integration is carried out by stacking ensemble learning. The experimental results show that the integrated model significantly improves the accuracy of text sentiment analysis and it can effectively predict the sentiment polarity of the text.

Data Clustering is the process of grouping the objects in a way which is identical to the objects in the same group than in other classes. In this paper, the clustering of data is used as k-means to assess the output of students. Machine Learning is an area used in all systems. Machine learning is used in education, pattern recognition, sports, industrial applications. Its significance increases with the future of the students in the educational system. Data collection in education is very useful, as data volumes in the education system are growing each day. Higher education is relatively new, but due to the growing database its significance grows. There are several ways to assess the success of students. K-means is one of the best and most successful methods. The secret information in the database is extracted using data mining to increase the output of students. The decision tree is also a way to predict the success of the students. In recent years, educational institutions have the greatest challenges in increasing data growth and using it to increase efficiency, such that better decision-making can be made. Clustering is one of the most important methods used for the analysis of data sets. This trial uses cluster analyses according to their features for section students in various classes. Uncontrolled K-means algorithm is discussed. The mining of education data is used for the study of the knowledge available in the field of education in order to provide secret, significant and useful information. The proposed model considers K-means clustering model for analyzing learners performance. The outcomes and future of students can be strengthened with this support. The results show that the K-means cluster algorithm is useful for grouping students based on similar performance features.

Development of cajuput plantation currently becomes the most important activity in KPH Bojonegoro since it provides an essential contribution to maintain the future viability of company. However, the growth performance of cajuput stand relatively varies one of which is influenced by planting design. This study aims to determine the optimum planting design for supporting cajuput stand development. It was conducted by evaluating two different planting designs that generally used for cajuput establishment, namely C1 (spacing 3 m x 1 m) and C2 (spacing 5 m x 1.5 m x 1.5 m). Five parameters were used to evaluate the growth performance and oil production of cajuput stand for each planting design, i.e., survival rate, quadratic mean diameter, basal area, harvesting biomass, and cajuput oil production. Data were collected by field measurement using a sampling plot 50 m x 50 m with six replications for each planting design. Comparison mean of cajuput growth performance between two planting designs were analyzed separately for each parameter using t-test. Results documented there were not a significant different for all parameters, except survival rate. The planting design C2 generated higher survival rate (94.9%) than planting design C1 (64.7%). The planting design C2 was recommended for cajuput development in KPH Bojonegoro. Besides requiring the lower planting density, the use of planting design C2 can optimize land utility with a similar productivity to planting design C1.

Authors: Bajpai Shalini
Published: April 2021

BACKGROUND Video laryngoscope is an important tool for orotracheal intubation in anaesthesia practice particularly in difficult airways. It provides an indirect view of glottis without the need of alignment of oropharyngeal-laryngeal axis. We compared the intubation characteristics of channelled versus non-channelled blades of King VisionTM Video Laryngoscope. METHODS In this study 60 patients were randomly allocated to two groups; group C were intubated with channelled and group NC with non-channelled blade of King Vision. We measured time for glottis visualisation and intubation time using both blades. Percentage of glottis opening (POGO), insertion attempts, intubation attempts, and ease of intubation were also assessed. RESULTS The time for glottis visualisation was 8.5 ± 3 seconds for group C and 7 ± 2 seconds for group NC. Intubation time was 24 ± 8.5 seconds for group C and 44 ± 5 seconds for NC. There was no statistical difference in POGO, insertion attempts, intubation attempts and ease of intubation between the two groups. CONCLUSIONS We concluded that the time for glottis recognition is longer but intubation time is shorter when using King Vision video laryngoscope channelled blade as compared to non-channelled blade.

Moreover, volcanic glasses are found in several stratigraphic units. The quantity of pyroclastic material in the study section (17–72%) is probably related to volcanic input in the basin. Concentrations of the trace and rare earth elements point to a predominantly acid source of ash material, except the Promzino and Ulyanovsk black shale formations linked to the mixed andesite-basaltic and felsic sources. Island arcs of the Northern Tethys basin and the High-Altitude Arctic Igneous Province are regarded as probable sources of the pyroclastic influx in the epeiric basin of the Russian Platform in the Jurassic-Early Cretaceous.

Background: Voluntary non-remunerated blood donation is a strategy adopted by World Health Organization aimed at ensuring safety and adequacy of blood supply. Sub-Saharan Africa has a high prevalence of hemoglobin disorders and therefore needs to adopt stringent measures in donor selection to ensure safety for the recipient of blood transfusion. This study aimed to analyze normal and variant hemoglobin among voluntary blood donors.
Methods: In this descriptive cross-sectional study, 100 prospective blood donors including 55 (55%) males and 45 (45%) females, aged 18–34 years were recruited. Capillary electrophoresis using the Minicap system was used for determining the hemoglobin variants in alkaline buffer (PH 9.4). Data analysis was done using SPSS version 20 and p-value < 0.05 was considered as the level of significance
Results: The mean age of the participants was 22.23 ± 3.3 SD years. The proportion of participants with genotype AA was 67 (67%), those with AS were 17 (22 %), while those with AC were 11 (11 %). While Hb A ≥ 90% was noted in 67 (67%) blood donors, Hb S was seen in 22 (22%) and Hb A2 > 3.5% in 57 (57%). Hb F > 2% was observed in 3% of the studied participants
Conclusion: Variant hemoglobin is common among blood donors and this should be taken into consideration whenever blood is being crossmatched for recipients of blood transfusion. Data from this study will be useful in raising awareness and genetic counseling.

“WOMEN’ WRITING” AS AN AREA OF DISCOURSIVE, GENRE AND NARRATIVE CONFLICTS (A CASE STUDY OF GERMAN-LANGUAGE FEMALE PROSE OF THE LATE XIX – EARLY XX CENTURY)
Authors: Eliseeva Aleksandra V.
Published: April 2021

The paper focuses on the phenomenon of “women’s writing”, a discussion about which began in the 1970s. Based on Elaine Showalter’s concept of “doubled-voiced discourse” as well as on Franco Moretti’s theory of literary forms development from the center to the periphery, which generates unstable compromises in the structure, its “cracks” and gaps, the article offers an interpretation of “women’s writing” as an area of increased conflict. The case study of three literary works of the late XIX – early XX century written in German language – Elsa Asenijeff’ essay “Women’s Riot and the Third Sex” (1898), Lou Andreas-Salomé’s novella “Fenitchka” (1898) and Minna Wettstein-Adelt’s novel “Are These Women? A Novel about the Third Sex” (1901) – demonstrates conflicts of discourses, genres and narrative strategies unfolding in these texts. The paper suggests the idea that such structural “cracks” and contradictions mark the departure from the boundaries and limits of contemporary patriarchal discourses and the dominant literary system.

Published: April 2021

A utilização da protensão como solução para estruturas de aço foi proposta desde a década de 1950 e, apesar de diversos estudos publicados, ainda não está difundida no meio profissional. A sua aplicação é feita de forma externa à estrutura e, entre suas aplicações, é recomendada para reabilitação e reforço. Seu método executivo é relativamente simplificado, uma vez que pouco se altera dos procedimentos executivos das estruturas de aço passivas e do concreto protendido. Este trabalho tem como objetivo analisar o comportamento de uma viga de aço reabilitada quando submetida às etapas de protensão. Para isso, serão aplicadas cordoalhas, causando flexão também no sentido de menor inércia do elemento estrutural. De acordo com o modelo proposto, pode-se observar que os esforços presentes na etapa executiva não superam a capacidade de suporte do elemento. Entretanto, determinadas fases de carregamento podem causar instabilidade caso não sejam verificadas corretamente.
Oil and gas potential of the deep-lying Jurassic and pre‑Jurassic deposits of the North of Western Siberia in unconventional traps
Authors: Shuster Vladimir L. , Punanova Svetlana A.
Published: April 2021

In-depth additional studies were carried out to assess oil and gas potential of deep-lying Jurassic and pre-Jurassic deposits of the northern territories of Western Siberia. As in previous work, the geological and mathematical program “Vybor” was used. Based on the first constructed series of model maps with probabilistic values of informative geochemical and geological parameters, the most promising both local and regional objects were selected.
Increasing complexity of the traps structure with depth was noted. As a rule, from the Cretaceous deposits to the Jurassic and Paleozoic, the type of trap from the predominant anticline (in the Cretaceous) changes to a much more complex combined one, which requires special approaches (and new technologies) to identify and explore such objects. Studies based mainly on seismic data indicate rather high oil and gas content of both the Paleozoic and Triassic deposits, which have a platform occurence and large thicknesses, as well as crystalline basement formations. In this regard, unconventional combined traps of deep-lying deposits of the North of Western Siberia are of significant interest in terms of incremental oil and gas resources and reserves.

Despite the long history of geological exploration and scientific research in the Caspian region many issues of its oil and gas geological zoning remain controversial, including justification the boundaries of oil and gas provinces at the ancient and young platforms: Pre-Caspian, Ciscaucasia-Mangyshlak and North-Ustyurt. This paper discusses problems of the ancient and young platforms sedimentary cover’s oil and gas zoning using the example of Pre-Caspian region. It is proposed to carry out oil and gas geological zoning of these regions with taking into account the types of the Earth’s crust sections and sedimentary cover’s hydrocarbon systems types, as well as the types of the main oil and gas complexes’ structures. The type of the Earth’s crust section is crucial upon identification oil and gas provinces boundaries; the type of hydrocarbon systems is in the foreground when identifying sub provinces; and the boundaries of oil and gas regions are determined by the main types of oil and gas complexes’ sections and structures.
In the Pre-Caspian province three sub-provinces are identified and their oil and gas potential is characterized. The proposed boundaries of the province closely coincide with the distribution contours of the Kungur saliferous strata with considerable thickness (hundreds of meters). Due to the lack of a clear structural boundary between the Paleozoic hydrocarbon systems the Pre-Caspian and Volga-Ural oil and gas provinces are proposed to be considered as a single marginal-continental oil and gas mega-province. The obtained materials and conclusions can serve as a basis for basin modeling and hydrocarbon resources forecast’s refinement.

The article presents the results of studies on substances with a biocidal effect in terms of their possible use as additives to drilling muds and fracturing fluids. The aim of the work was to identify the most effective biocides by examining their action on aerobic and anaerobic bacteria, fungi, sulfate-reducing bacteria (SRB), and a consortium of microorganisms. Various chemicals have been considered, due to a constant and overriding goal to find the one with the highest activity, and above all, the ones that have not yet been tested. Particular attention was paid to substances that, apart from known biocidal properties, have also the ability to neutralize hydrogen sulfide, and to reduced sulfur compounds (H2S scavengers), and the so-called “green biocides”, i.e. those that are considered safe for the environment. Most of the tested biocidal agents were effective against aerobic and anaerobic bacteria, while 10 out of 12 showed good or very good activity against SRB (low MIC and MBC values), including 3 out of 4 H2S scavengers. On the other hand, only some biocidal agents proved to be effective against fungi and microbial consortium; among them were agents containing quaternary ammonium compounds (Bardac LF and Barquat CB-80), triazine derivatives (Biostat and Petrosweet HSW 82165) and DBNPA (Biopol C-103L). Bardac LF and Barquat CB-80, together with the mixture of Grotan OX and Preventol GDA 50, upon introduction to the drilling mud and fracturing fluid, were superior over other biocidal agents (Biostat, Petrosweet HSW 82165 and Biopol C-103L), showing the full activity at 800 ppm. Environmentally friendly biocide Aquacar THPS 75 appeared to be the least effective.

The aim of the work was to present the issue of eco-efficiency, based on the PN-EN ISO 14045:2012 standard in relation to the production of fatty acid methyl esters (FAME). The ecoefficiency analysis takes into account economic and environmental aspects in the improvement of products and processes / technologies. Eco-efficiency considers the product and technology throughout the life cycle, from the construction phase, through use to decommissioning. The impact on the natural environment is assessed on the basis of: consumption of energy, materials, dust and gas emissions, waste and sewage. Total costs include: production costs, raw material costs, costs during the use phase including maintenance, repair and operating costs, product disposal or recycling. The eco-efficiency analysis is helpful in making decisions regarding the selection of a new product or designing a new technology, and enables the selection of the variant that is the most economical and has the least possible impact on the natural environment. These issues are particularly important in the case of biofuels. The rapid growth of their production and the European Union’s policy, which aims to increase the share of energy from renewable sources, cause concerns of many experts regarding the threats related to the production of biofuels, both for the environment and food security. In particular, efforts are made to minimize the amount of waste and residues by implementing the idea of a circular economy. This approach promotes the development of new technologies that are more environmentally friendly. Due to the regulations set out in the RED and RED II Directives, there is a chance that the biofuels will have a less negative impact on the environment. This results from the obligation to certify compliance with the sustainability criteria, which is carried out by voluntary systems recognized by the European Commission, such as the KZR INiG System.
I Know Where Oysters Lie
Authors: Moore Sarah Jane
Published: April 2021

This research honours the Baludarri (Sydney Rock Oyster). It is interdisciplinary in its approach and showcases the work of Australian born artist, Sarah Jane Moore. It presents key findings from an artistic residency at UNSW in Sydney, Australia, through the modalities of image, song and text. It highlights the importance of the humble oyster and maps an art-meets-science approach where Moore’s creative thinking seeks inspiration from her relationship with the work of an Indigenous scientist, Laura Parker. The oyster is Moore’s living data and the work maps the deep listenings necessary to foster communities that value reefs, hold oceans as sacred and regard the oyster as a precious entity to be celebrated, protected and nourished.
