Dynamics of codfish stocks in the North Atlantic region
Authors: Krovnin A. S. , Melnikov S. P.
Published: August 2023

Purpose: to investigate the features of the long-term dynamics of codfish stocks in the North Atlantic region as a basis for predicting their state and sustainable fishing (exploitation).

   Materials: data on spawning stock biomass, abundance of recruitment at age 0 to 3 years, survival indices at early ontogenesis stage for 11 Atlantic cod stocks, 6 Atlantic haddock stocks, and 4 saithe stocks for the period 1946–2020

   Methods: a comparative analysis of the above time series based on their statistical processing.   Novelty: For the first time, a 50–60-year cycle which characterizes the long-term variations of the Atlantic Multidecadal Oscillation index, were revealed in the long-term fluctuations of the Northeast Arctic cod recruitment. This assumes a relationship in the long-term variations of two parameters under consideration.

   Results: The significant interannual variability of all characteristics was identified for each of the 21 commercial fish stocks under consideration. Statistically significant positive correlations were found between changes in recruitment abundance of Atlantic cod in the Northwest Atlantic and Atlantic cod, Atlantic haddock, and saithe in the areas of Greenland, Iceland, North and Baltic Seas. Changes in the recruitment abundance of Labrador cod and Northeast Arctic cod in the Barents Sea are opposite.

   Practical significance: the results of this work can be used to improve the methods of the medium-range and long-range forecasts of codfish catches in the North Atlantic region.

Published: August 2023

The aim of the paper is to assess the impact of climate changes and oceanographic conditions on the distribution of cod stocks in the Barents Sea in recent decades.

   The material for the study was oceanographic data obtained during surveys in the Barents Sea by PINRO and other available information on hydrometeorological conditions of the sea in 1981–2021, as well as data onRussian catches of cod in the Barents Sea based on bottom trawl fishing operations.

   Methods of descriptive statistics as well as comparative, correlation and regression analyses were applied.

   Results: The modern changes in the climate and oceanographic conditions of the Barents Sea are described. Since the early 1980s, the warming has been observed against the background of increasing storm activity, having peaked in 2016. After that, despite still warm and low-ice conditions, there has been a cooling trend in the Barents Sea. Under climate changes in recent decades, cod made increasingly long migrations north and east, spreading more widely in the feeding areas. The most informative predictors in assessing the impactof climate changes and oceanographic conditions on the distribution of cod stocks in the Barents Sea were Arctic ice extent, area-averaged temperature at a depth of 100 m, Atlantic water area in the 50–100 m layer, and parameters of the Barents Sea thermal frontal zones.

   Practical significance: The obtained results are useful for a better understanding of the processes occurring in the Barents Sea ecosystem and, in the future, will be used to predict cod distributions in the sea, depending on oceanographic conditions and climate changes.

Authors: Datsky A. V. , Sheybak A. Yu. , Batanov R. L.
Published: August 2023

The purpose of the work: revealing the features of the distribution of the catches of aquatic biological resources by area, timing and fishing gear in the course of modern fishery in the Russian waters of the Bering Sea.

   Methods used: the catches of marine fish and invertebrates were considered based on operational information on the fishery according to the data of daily ship reports of the sectoral monitoring system. The ratio of the catch of the main species of aquatic biological resources and by-catch objects in 10 fishing gear was analyzed according to the data of 50 marine and 28 coastal expeditions.   Novelty: elements of novelty are generalized materials on the spatial and bathymetric distribution of the catch of the main fishing objects for the fishing industry in the western part of the Bering Sea for the period 2003–2021. The distribution of catches of aquatic organisms is given by types of vessels used in the fishery, depths and terms of fishing, as well as various fishing gear. Data on the ratio in commercial catches of both individual fish species and some species in the combined groups of «flounders», «rockfishes», «sculpins», «skates» and «grenadiers» are presented.   Practical significance: the results of this study can be used in forecasting the dynamics of stocks of aquatic biological resources, creating a system of interlocked quotas and formulating recommendations for the transition of specialized fisheries to multi-species fisheries.

Authors: Adesope O. A. , Akanbi O. A. , Apanpa K.A.
Published: August 2023

Three representative samples each from residual and termite reworked soils were collected within the premises of The Polytechnic Ibadan, southwestern Nigeria. Their suitability for construction purposes was determined by assessing their geotechnical and geochemical properties. Geotechnical tests carried out include moisture content, specific gravity, Atterberg limits, particle size distribution, compaction, UCS test and CBR. AAS was used to analyze the oxides composition of the soils. Both soil types were classified as low – intermediate plasticity clays with liquid limit between 25.5%-43.1%. The CBR values ranged from 80% – 85% and 20% – 50% for termite reworked soils and residual soils respectively. UCS ranged from 212.1KPa – 226.3 KPa and 191.7KPa – 200.0 KPa for the termite reworked and residual soils respectively. The OMC and MDD values for termite reworked soil ranged from 5.8% – 8.4% and 1968 kg/m3 – 2020kg/m3 respectively and between 12% – 15.2% and 1800 kg/m3-1940 kg/m3 for residual soils. Geochemistry result shows that the termite reworked soils contained a mean of 60.1% SiO2, 31.05% Al2O3, 1.7% CaO and 4.9% Fe2O3 while the residual soils contained a mean of 59.8% SiO2, 28% Al2O3, 1.6% CaO and 4.6% Fe2O3. This accounts for the better geotechnical properties exhibited by the termite reworked soils.

Authors: Sisodia Yogendra
Published: August 2023

Researchers are becoming more interested in extracting useful information from legal documents thanks to the development of large-scale language models in natural language processing (NLP), and deep learning has accelerated the creation of powerful text mining models. Legal fields like contracts benefit greatly from semantic text search since it makes it quick and easy to find related clauses. After collecting sentence embeddings, it is relatively simple to locate sentences with a comparable meaning throughout the entire legal corpus. The author of this research investigated two pre-trained language models for this task: MiniLM and Roberta, and further fine-tuned them on Legal Contracts. The author used Multiple Negative Ranking Loss for the creation of sentence transformers. The fine-tuned language models and sentence transformers showed promising results.

Published: August 2023

Smartphones are extensively used for communication, business, study, entertainment, and other purposes in everyone's daily life. Unfortunately, using the smartphone for prolonged periods causes several problems. The development of a complicated cluster of clinical symptoms known as "text neck syndrome" may be linked to the improper usage of personal devices, especially mobile phones. In addition, typical postures while using mobile phone devices can cause musculoskeletal problems. Various technologies are being considered to keep track of health and identify problems unobtrusively. This paper employs software-defined radio (SDR) based RF sensing and machine learning (ML) algorithms to develop a testbed for detecting text neck syndrome and classifying healthy and unhealthy postures. Specifically, fine-grained orthogonal frequency division multiplex (OFDM) samples are leveraged for channel state information (CSI) acquisition for detecting neck tilt angles while using the mobile phone. For classification purposes, the ML algorithms are used, and their performance in terms of prediction time, training time, and accuracy is assessed. The performance evaluation results of the testbed validated that this platform can faithfully detect and classify healthy and unhealthy postures with maximum accuracy of 99.9% with fine kth-nearest neighbors (KNN). The developed testbed has a considerable clinical impact on improving human health.

THE FIGURE OF THE EXISTENTIAL OUTCASTIN THOM GUNN'S EARLYPOETRY
Authors: Serhan Qassim Salman , Kadhim Nadhim Fadhil
Published: August 2023

Thom Gunn (1929-2004), baptized Thomson William Gunn, kept moving from one poetic mould into another, rejecting to commit himself to any school. He experienced bothBritishandAmericantraditions,but he refused to be under the garment of either. Instead, he preferred to call himself an Anglo-American poet forging as such a bridge between the two trends. In addition, Gunn was fascinated by Existentialism, which urged him to employ the figure of the existential outcast thatlies at the centreofhis poetry and reflects much of his personality and attitudes towards his surroundings.
This paper is a part of an M.A thesis entitled ''The Figure of the Existential Outcast in Thom Gunn's Poetry,'' prepared at the University of Al-Qadisiya, College of Education, Department of English.
Throughout his career, Gunn showed a deep impact of Existentialism, which inspired and underscored the bulk of his poetry. He was a devoted existential disciple who further spread the thoughts that were central to this philosophy. B. C. J. Hinton argues that "The extent of [Gunn'] involvement…goes well beyond the merely fashionable, and its influence lies behind almost all of his work." 1 He was attracted to such themes as man's freedom, will-to-power, the importance of choice, meaning making, risk and action, among other existential ideas.2In addition to his academic journey to Paris, Gunn was first introduced to Existentialism by his friend Tony White, "It was he (Tony White) who first get me to read Sartre's novels and Camus' plays,"3 Gunn writes.

Published: August 2023

The opposition between literary monuments is a phenomenon that has afflicted the world of literature since historical times, and perhaps between different nations, and Arabs are fond of writing oppositions, matching, dividing poems, dividing them, and simulating them. Poets throughout the ages have sought to oppose the effects of their well-known counterparts, admiring them or emphasizing their superiority over them. Among these oppositions, which received great attention, were the opposition of the Lamiyyat, as many poets opposed it, including the opposition of al-Tughrafi in his poem Lamiyat al-Ajam, the poem of the Lamiyat of the Arabs by al-Shanfriuth, the opposition of Nir al-Tabrizi, the poem of Lamiyat al-Ajam in his poem marked Lamiyat al-Turk.
Da Segregação Residencial à Conformação de uma Zona de Sacrifício na Cidade do Rio de Janeiro
Authors: Tavares Thiago Roniere
Published: August 2023

Este trabalho tem como objetivo analisar a conexão entre os fenômenos de segregação residencial e de injustiça ambiental, baseada nos impactos urbano-ambientais originados desde a instalação de uma usina siderúrgica. Para discutir estes fenômenos e concatenar seus processos, nossa investigação terá como estudo de caso o bairro de Santa Cruz, localizado na cidade do Rio de Janeiro (RJ), centrada na caracterização das condições de segregação residencial quando comparadas a outros bairros da cidade do Rio. Este contexto de segregação residencial, sem ser resolvido, é sobreposto pelas condições de injustiça ambiental, vivenciadas por seus moradores, em virtude dos efeitos nocivos gerados pela siderúrgica Ternium Brasil. A correlação entre ambos os fenômenos conforma o que se denomina no campo da Ecologia Política como zona de sacrifício. Ao analisar esta conformação em Santa Cruz, pudemos ir um pouco além do que é apresentado na literatura acadêmica enquanto zona de sacrifício. Assim, em que pese a sobreposição mencionada, adicionamos o elevado consumo de recursos hídricos pelasiderúrgica, como dinâmica que complementa a composição da zona de sacrifício.

Trade, Businesses, and Economy of U.K. Post-Brexit— A Quantitative Analysis
Authors: Dave Brij Behari
Published: August 2023

Many studies have been carried out on Brexit’s economic impact on the UK, EU27, the US, and the rest of the world. Depending on the assumption of whether Brexit will be a hard Brexit or a soft Brexit, almost all studies predicted Blows to the economies of the UK and the EU, with a more severe blow to the UK economy. With the Trade Co-operation Agreement signed by the end of the year 2020 and the actual divorce of the UK from the EU with effect from 01-01-2021, the actual effects of Brexit came to reflect in various economic data reported by various national and international agencies. This paper makes an effort to analyse these hard data and examine the Brexit impacts on various sectors. It has also taken clues from the various surveys on the problems faced by businesses on the border, shortage of labour, etc. In February 2023, a protocol on Northern Ireland was finalized which became a part of the EU-UK withdrawal agreement that now ensures that a hard border is avoided for the UK export items on the island. This protocol was agreed upon between the United Kingdom, Northern Ireland (UK), and the European Union (EU) as the final settlement designed to protect Ireland’s economy and Belfast Agreement. The study concludes that the UK has done a relatively good job of managing the inevitable Brexit disruptions, including transitional measures for border softening. In order to achieve the laudable goal of having the best border in the world by the year 2025, the UK will require streamlining the Regulatory Control Systems. The UK has also entered into a Comprehensive Agreement with Trans-Pacific Partnership. But much is still to be done on the Domestic Regulatory Reforms front. Unless the UK uses the coming years to engage in putting in place proper, meaningful, and comprehensive regulatory reforms, the opportunities for Brexit may be wasted.

The score of the expected food pattern, the quantity, variety, and quality of food consumed, can be used to assess a person's eating quality. The fact that Pekanbaru City's PPH score for 2020 is only 84.7 points below the optimal value demonstrates that its citizens' food consumption is not yet varied and nutritionally balanced. This study examines PPH scores for household food consumption among P2L participants and elements that affect the caliber of food consumed in P2L-participating families. This study used a survey methodology, with the respondent number being 65-person total sample chosen via stratified random selection. Analysis of PPH scores for household food consumption in P2L participants used descriptive statistics. In contrast, inferential statistics and multiple linear regression are used to analyze the variables that affect the P2L household food intake PPH score. The results showed that the P2L participant's household food consumption PPH score was 85.4. P2L program increases PPH score in Pekanbaru.

Published: August 2023

This study verified the mediating effect of the experiences of homeless people on the street in using relevant support services on the relationship between their health and attempts to escape homelessness. The analytic results serve as data for preparing more effective policies to support homeless people and ultimately encourage their successful escape from homelessness. A survey was conducted with 116 homeless people living on the street in the Busan area. The survey results showed that their deteriorating health had a positive effect on their experiences with support services for homeless people and an escape from homelessness. Second, their experiences using relevant support services had a mediating effect on the relationship between their health and attempts to escape homelessness. Based on the analytic results of this study, measures are proposed for encouraging homeless people on the street to successfully escape homelessness. First, the facility-oriented street homeless support service delivery system should be diversified, and second, services based on personal needs such as self-reliance or facility protection should be developed and distributed. Third, service information accessibility should be improved so that homeless people can recognize the services they need. This study proposed a realistic alternative by empirically identifying the relationship between the experience of using social welfare services and the experience of leaving homelessness.
