Published: May 2023

One new species, Placoneis modaomensis, found in freshwater environment from tributary of the Pearl River which lies in Modaomen Channel, Zhuhai County, Guangdong Province, China, is described based on light and scanning electron microscope observations. P. modaomensis sp. nov. has the morphological features that are typical for the genus, including external terminal raphe fissures curve to the opposite sides and areolae with internal volate occlusions. The new species is similar to P. amphibola (Cleve) E.J. Cox, P. amphiboliformis (Metzeltin, Lange-Bertalot & Soninkhishig) Vishnyakov, P. parvapolonica Lange-Bertalot & Wojtal, P. clementispronina Lange-Bertalot & Wojtal and P. nanoclementis Lange-Bertalot & Wojtal in the shape of the valves and having course striae but it can be easily distinguished by the two main morphological characteristics: external central raphe endings bent in the opposite directions, and areolae covered by volate occlusions externally. The latter feature appears to be new for taxa assigned to the genus Placoneis. Data on the associated diatom flora and its ecology are also given. These findings increase our understanding about the morphology of Placoneis in general and its and distribution of the genus in China.
FEATURES OF MYOFASCIAL PAIN SYNDROME OF CERVICAL LOCALIZATION IN YOUNG PATIENTS WITH FORWARD HEAD POSTURE
Authors: Logvinenko G. V. , Voloshyna M. I.
Published: May 2023

One of the most common variants of non−specific muscle pain is myofascial one. To establish the features of myofascial pain syndrome of cervical localization and its impact on daily life in young patients withforward head posture, 37 patients were examined. There were performed clinical−neurological, vertebro−neurological examination (visual diagnosis of static disorders, manual diagnosis, kinesthetic examination of muscles), photogrammetric measurement of craniovertebral angle, assessment of neck pain on a visual analog scale and its impact on patients. In all patients a visual diagnosis revealed a shift of regional center of gravity at the cervical level forward with the formation of the head forward posrture, which was confirmed by measuring the value of the craniovertebral angle − 48.3±1.56 °. There was a negative correlation between the value of craniovertebral angle and assessment of pain on a scale (r = −0.91, p < 0.05), as well as between the value of craniovertebral angle and index of vital disorders in neck pain (r = −0.93, p < 0.05), which indicates the effect of forward shifting the regional center of gravity on the severity of cervicalgia and the degree of its impact on the daily lives of young patients. Based on the results of the study, conclusions were drawn. Myofascial cervical pain syndrome in young patients with head forward posture is characterized with a bigger number of muscle groups involved into the pathological process with shortening of the head and neck extensor muscles as well as the formation of active trigger points, greater severity of neck pain and the negative impact of cervicalgia on daily life compared to the patients with a neutral head posture.

Key words: forward head posture, myofascial pain syndrome, trigger point, cervicalgia.

Postoperative sternomediastinal infections significantly affect morbidity and mortality, as well as the hospitalization duration and treatment cost for cardiac surgery patients. The use of median sternotomy has a number of complications, primarily infectious, which can occur with the formation of superficial or deep wound infection, diastase and fragmentation of the sternum, and sometimes with destabilization of the chest bony skeleton. The development of sternal osteomyelitis is associated with a significant reduction in long−term survival. The results of treatment for the patients with the sternum osteomyelitis after sternotomies, being at the State Institution "V. T. Zaitsev Institute of General and Emergency Surgery of the NAMS of Ukraine" in Kharkiv within the period of 2014−2020, have been analyzed. Diagnosis of patients with osteomyelitis of the sternum comprised fistulography, multispiral computed tomography, ultrasound. The material for the bacterial study was the discharges of a sternal wound. Antibiotic susceptibility of isolated bacterial cultures was studied by disco−diffusion and in agar. There were 32 strains of microorganisms, representatives of different taxa. S. aureus was dominant and accounted for 23.81 % of the total number of isolates of this genus. Among antibiotics, the most effective in vitro were lincomycin and especially carbapenems (imipenem). When treating the patients with sternal osteomyelitis, VAC therapy was used, as well as open wound management by dressings depending on the wound process stage. The results of the study suggest that multi−slice computed tomography should be preferred in the diagnosis of osteomyelitis of sternum, which allows the diagnosis verification in 98 % of cases, and the use of ultrasonography is important to monitor the clearance and healing of sternotomy wounds. The use of VAC therapy has helped to reduce the length of hospital stay of patients.

Key words: sternum osteomyelitis, VAC therapy, multispiral computed tomography, bacterial culture.

« Ceci n’est pas une pipe ». Négation et création artistique
Authors: Korff-Sausse Simone
Published: May 2023

L’auteure se propose d’explorer la notion de négation en tant que source de la créativité artistique. Il s’agit de lire le texte de Freud en regardant les œuvres de certains artistes (Magritte, Beckett) sur la négation, en particulier en remettant en question l’opposition binaire entre négation et affirmation. Les œuvres de ces artistes produisent des oxymores qui échappent à un jugement qui décide (Freud), mais laissent la décision en suspens, de savoir si c’est vrai ou si c’est faux. Ainsi pour Magritte, la négation « ceci n’est pas une pipe » n’amène pas à l’affirmation « ceci est une pipe ». La référence théorique de l’auteure est W. R. Bion, dont le modèle de l’appareil psychique peut rendre compte de ces processus. La « capacité négative » est une forme de négation, mais qui ouvre un champ de transformations, qui sont la source des créations artistiques, ce dont la rencontre analytique de Beckett et de Bion donne une illustration.
Les fonctions défensives de la plainte dans le commerce à l’objet
Authors: Pelladeau Élise
Published: May 2023

Dans le cadre de cet article, nous envisagerons la « plainte », et plus spécifiquement l’action « de râler », comme un processus antidépressif qui permettrait de jouer entre plaisir et déplaisir avec les représentations substitutives de l’objet perdu. Nous questionnerons les destins de la plainte dans la rencontre transférentielle et la manière dont le travail analytique mobilise puis assouplit l’arsenal défensif dans la rencontre avec l’objet. À travers le cas de Georges, patient suivi en cabinet libéral, nous questionnerons le retentissement de la perte d’objet et ses aménagements défensifs pour décrire en quoi l’action même de « râler », pourrait se lire comme un équivalent masturbatoire, écran des objets antérieurement perdus en cascade. Nous considérerons les fonctions hallucinatoires de la plainte, et l’érotisation de l’anticipation de la perte, au service des mobilisations défensives, tout en envisageant leur revers dans le travail analytique.
Reinforcement learning-based AI assistant and VR play therapy game for children with Down syndrome bound to wheelchairs
Authors: Mariselvam Joypriyanka , Rajendran Surendran , Alotaibi Youseef
Published: May 2023

Some of the most significant computational ideas in neuroscience for learning behavior in response to reward and penalty are reinforcement learning algorithms. This technique can be used to train an artificial intelligent (AI) agent to serve as a virtual assistant and a helper. The goal of this study is to determine whether combining a reinforcement learning-based Virtual AI assistant with play therapy. It can benefit wheelchair-bound youngsters with Down syndrome. This study aims to employ play therapy methods and Reinforcement Learning (RL) agents to aid children with Down syndrome and help them enhance their abilities like physical and mental skills by playing games with them. This Agent is designed to be smart enough to analyze each patient's lack of ability and provide a specific set of challenges in the game to improve that ability. Increasing the game's difficulty can help players develop these skills. The agent should be able to assess each player's skill gap and tailor the game to them accordingly. The agent's job is not to make the patient victorious but to boost their morale and skill sets in areas like physical activities, intelligence, and social interaction. The primary objective is to improve the player's physical activities such as muscle reflexes, motor controls and hand-eye coordination. Here, the study concentrates on the employment of several distinct techniques for training various models. This research focuses on comparing the reinforcement learning algorithms like the Deep Q-Learning Network, QR-DQN, A3C and PPO-Actor Critic. This study demonstrates that when compared to other reinforcement algorithms, the performance of the AI helper agent is at its highest when it is trained with PPO-Actor Critic and A3C. The goal is to see if children with Down syndrome who are wheelchair-bound can benefit by combining reinforcement learning with play therapy to increase their mobility.
A framework for long-lasting, slowly varying transient dynamics
Authors: Liu Ankai , Magpantay Felicia Maria G. , Abdella Kenzu
Published: May 2023

Much of the focus of applied dynamical systems is on asymptotic dynamics such as equilibria and periodic solutions. However, in many systems there are transient phenomena, such as temporary population collapses and the honeymoon period after the start of mass vaccination, that can last for a very long time and play an important role in ecological and epidemiological applications. In previous work we defined transient centers which are points in state space that give rise to arbitrarily long and arbitrarily slow transient dynamics. Here we present the mathematical properties of transient centers and provide further insight into these special points. We show that under certain conditions, the entire forward and backward trajectory of a transient center, as well as all its limit points must also be transient centers. We also derive conditions that can be used to verify which points are transient centers and whether those are reachable transient centers. Finally we present examples to demonstrate the utility of the theory, including applications to predatory-prey systems and disease transmission models, and show that the long transience noted in these models are generated by transient centers.

Watermarking in Medical Image
Authors: Nashwan Alsalam Ali  , Iman I. Hamid
Published: May 2023

Medical image security is possible using digital watermarking techniques. Important information is included in a host medical image in order to provide integrity, consistency, and authentication in the healthcare information system. This paper introduces a proposed method for embedding invisible watermarking in the 3D medical image. The cover medical image used is DICOM which consists of a number of slices, each one representing a sense, firstly must separate the ROI (Region of Interest) and NROI (Not Region Of Interest) for each slice, the separation process performed by the particular person who selected by hand the ROI. The embedding process is based on a key generated from Arnold's chaotic map used as the position of a pixel in the slices with the highest saturation for embedding a secret message in the NROI because the ROI contains the information of the ill, so it cannot be modified. The evaluation of the proposed method using PSNR and MSE shows good results according to both requirements of the watermark system, the invisibility and quality of the watermarked medical image where the PSNR value is up to 43.3936 and MSE is up to 0.000041.
Reducing Delay and Packets Loss in IoT-Cloud Based ECG Monitoring by Gaussian Modeling
Authors: Fadhel Ahmed A. , Hasan Hamid M.
Published: May 2023

Abstract— Health monitoring based on the internet of things (IoT) and cloud computing is regarded as a hot topic to research. However, such systems often face issues with delay and throughput due to the large amount of data that must be transmitted from sensors to the cloud. One important type of data for health monitoring is Electrocardiogram (ECG) signals, which generate a large amount of data to be transmitted. This research treats this problem by modelling these signals in order to reduce their size using Gaussian approximation. The cloud server is an MQTT broker to which the sensors publish their data via a gateway. The Gaussian parameters are calculated in the gateway, which act as a Fog layer, before published to the broker. The monitoring devices can subscribe to the broker and access the transmitted data. Our experiments were conducted using the MIT–BIH dataset and a real broker (HiveMQ). The results showed that the system was able to significantly reduce delay in transmitting data and prevent loss of information. Without using the Gaussian approximation technique, the system was only able to monitor a limited number of patients (17 for Qos1 and 23 for Qos0) without losing information. However, when using the Gaussian approximation model with five functions, the system was able to monitor many more patients (78 for Qos1 and 100 or more for Qos0) without losing any data.

Feminization of Migration
Authors: Gnanadev Neema
Published: May 2023

The migration of women has emerged as an important field of research within the larger domain of migration studies and is being explored under various disciplines. Despite the growing proportion of women in the global migration pattern, the contribution of women to the migrant labour force has been largely overlooked. The paper highlights the fact that the feminization of migration has undoubtedly increased the visibility of women in the migration, but much more needs to be done in terms of evolving policies for ensuring their protection and security, and above all empowering them and increasing their participation in the labour market. The findings of the study also suggest that though females accompany their spouses, their economic role need not be undermined. The work participation rate of female migrants as compared to female non-migrants increases in rural-urban migration over a period of time as is evident from the data. In a nutshell, the significance of economic factors in determining female migration should be given greater importance in migration studies.

The mule is a sterile hybrid domestic animal that results from the breeding of a male donkey with a female horse, understanding the reproductive biology of these species is very critical. The goal of this paper was to perform a comparative and more accurate histomorphometric of the testicles in Barb horse, donkeys and mules. Microscopic examinations and histological description were carried on genital tract of horses, donkeys and mules healthy and mature; this study was conducted during April-May 2018. The histological and the morphological results shows a similarity between the two equine species and the infertile hybrid for the testicles, the epididymis and the vas deferens. However, the difference was presented on the morphometric data; vas deferens was more voluminous in the horse and donkey than a mule. Moreover, the differences were significantly higher for the surface of the seminiferous tubules and for the epididymis. The lumen of the seminiferous tubules in mule was significantly higher than in the horse and donkey. Absence of gametes in the epididymal cavity and lower number of gametes in the mule. Furthermore, we have noted the presence of spermatozoa in one mule 16.67%. Therefore, the mule could complete development of spermatogenesis.

The present study aims to conduct a review on the potential use of insect meal as an alternative protein source in poultry feed, particularly to serve the rearing of free-range chickens. Insects are already part of the diet of birds in their natural habitat, and the availability of low-cost alternative foods with low environmental impact is essential for the development of the activity. The review comprehended studies that used meals consisting of silkworm (Bombyx mori) chrysalis, earthworm (Eisenia foetida), housefly (Musca domestica), black soldier fly (Hermetia illucens) and mealworm beetle (Tenebrio molitor) to replace plant-based protein sources. In general, insect meals have a high content of crude protein and ether extract, as well as an essential amino acid profile suitable for poultry feeding. The addition of insect meal in poultry feed normally shows good results as to growth performance and egg production, without causing a negative effect on carcass characteristics, meat sensory quality and egg quality, presenting itself as an alternative protein source with good prospects for replacing plant-based sources in poultry feed.

This study aims to describe the relationship between the process of internationalization of a Brazilian university and its triple mission of teaching, research and outreach activities. To this end, the study discusses the interface between internationalization of higher education and global citizenship education (GCE) focusing on the United Nations Sustainable Development Goal (SDG) 4 – Quality Education – which aims to guarantee inclusive, equitable and quality education for all. GCE is related to SDG4 as it acknowledges interrelationships of the global, national and local aspects of higher education. So as to reflect about these interrelations, the study reports on an on-going project  proposed in a university in Brazil whose aim was to link research results through an outreach project to develop the internationalization of small companies in the State of Espirito Santo, in connection with another project and university in Spain. The study draws on a theoretical-empirical, qualitative research based on secondary data with a corpus composed of 20 studies produced in the Brazilian university and the needs analysis carried out in the Spanish university to illustrate and discuss the interconnections between innovation, internationalization and GCE in relation to SDGs 4. The internationalization of the Brazilian university was analysed in relation to the university's triple mission of research, outreach and teaching activities/opportunities. The results of the analysis suggest that the internationalization of that institution is related to its triple mission of teaching (analysed in the Business Administration courses of the two universities involved), research (analysed through corpus analysis results) and outreach activities (analysed in the outreach/internationalization projects of the two institutions involved). Preliminary findings of the project suggest that the process of internationalization of the universities involved is related to the SDG4 insomuch as GCE is concerned.
The thick description of Clifford Geertz: An anti-scientific Approach to Anthropology
Authors: Balmaceda Facundo Guadagno
Published: May 2023

In this article, I analyse the ‘thick description’ notion developed by Clifford Geertz to explore its scope and limitations. It is not my intention to refute or consider invalid the approach developed by Clifford Geertz;  on the contrary, it is on his basis that I propose some corrections that are loose in his epistemological system. Some of his notions can be clarified, and others are wrong. I will discuss his (i) ontology, (ii) individualistic method, (iii) arbitrary notion of truth and (iv) the development of what a ‘thick description is’. To analyse this concept in detail, I evaluate how it is operationalised in some of the author's texts. The analysis shows its limited explanatory capacity due to its idealistic approach to the concept of culture, which overlooks other approaches in anthropology. Finally, I conceptualise thick description by adding materialistic properties to it.

Electricity Distribution system in Sri Lanka consists of 33 kV, 11 kV and LV (400V/230 V) networks. Providing reliable supply to the end user is a challenging task to any utility. Therefore, utility is committed to develop its network to provide reliable supply to electricity users by investing in system developments. In this research, a methodology is introduced for selecting cost-effective solutions to improve the reliability of the 33 kV and 11 kV distribution systems among different proposals. Improvement of conductor, its insulation and protection of short duration faults are focused to develop the system in this research. Part of the method developed includes a software tool (named as DisFeeRIA) to analyse the reliability indices and economic parameters for the relevant proposal. Database of the DisFeeRIA software tool includes failure rate improvement, mean time to repair and costing of each option under consideration. Medium Voltage Underground Cable (MVUGC), Medium Voltage Aerial Bundle Conductor (MVABC), Medium Voltage Covered Conductor (MVCC), Room Temperature Vulcanizing (RTV) Si-R coating on existing bare overhead line ceramic insulators are considered as options for improving conductor and its insulation. One of the latest and innovative technologies used in distribution network, Pulse Closing Technology, is used to reduce short duration faults (momentary interruptions) and enhance the lifetime of the equipment used in distribution networks. Developed tool and method were tested by a case study done for distribution network in Western Province South – 01 of Ceylon Electricity Board (CEB). Three (03) feeders were selected in different areas from Urban, Coastal and Rural for this purpose. MVCC and RTV Si-R coating for existing Medium Voltage Bare Overhead lines can be used for improving the reliability of Coastal, Urban and Rural distribution feeders in a cost-effective manner after proper analysis, based on technical and economic aspects. However, depending on the safety concerns, MVUGC or MVABC can be used irrespective of the economical aspect. Intelirrupter pulse closers can be used to replace traditional auto recloses, especially with MVUGC, MVABC and MVCC in rural feeders. It helps to reduce momentary interruption failures and enhance the equipment lifetime by reducing thermal and mechanical stress on all distribution equipment and cables. Furthermore, it improves the power quality of the system.

Lateral Distortional Buckling (LDB) is a mode of instability in Steel-Concrete Composite (SCC) beams that is yet to be fully understood by the structural engineering research and design community. This work investigated numerical methods to understand the LDB behavior of SCC beams under negative moments that exhibit nonlinear behavior. Focus of the study was to develop and validate 3-Dimensional finite element (FE) models which capture the LDB behavior of SCC beams precisely. Detailed 3-Dimensional FE models of the SCC beams were developed using ABAQUS. For modeling concrete, a nonlinear damage plasticity model was considered. A quad-linear curve was used to describe the stress-stain relationship for the steel beam. The stress-stain relationship for the rebar was described using a bi-linear curve while an elastic perfectly plastic model was assigned to the headed stud shear connectors. Steel hardening behavior was simulated using an isotropic hardening model. The interaction between the concrete slab, steel beam, and studs was described using appropriate interface elements combined under suitable constraints. The FE model’s accuracy was validated by results obtained from previous experiments found in literature together with a brief description of the experiments done by previous researchers to ensure completeness. Validation of the model was done by comparing Moment-Rotation curves obtained from the experimental tests, lateral displacements of the bottom flange along the axial direction and comparison of the failure modes between the numerical model and experimental test specimens. It was observed that the maximum relative error for the ultimate moment capacity of the composite beams from FE analysis and the experimental tests was less than 2% which shows that the FE model was in strong agreement with the experimental results. Accordingly, the numerical model developed herein proves to be capable of accurately representing the LDB phenomenon.

Steel jacketing has become an attractive strengthening technique for reinforced concrete (RC) columns due to ease of construction and less space requirement. The steel cage consists of angle sections placed at corners and held together by battens at intervals along the RC column height. A numerical investigation of the effective use of steel jackets as a strengthening technique in RC columns is presented in this paper. First, the finite element models of the strengthened column were developed and validated using past experimental data. Then, with the validated model, six sets of steel jacket sections with modified cross-sections such as batten spacing, batten thickness, batten width, end batten width, L angle thickness and steel jacket height were tested under constant axial and lateral loading to understand the effectiveness of steel jackets as the strengthening technique. AnunstrengthenRC column were also analysed to compare the performance of a similar column strengthened by steel jackets with modified parameters. It was shown that strengthening RC columns with steel jackets was effective in enhancing the lateral performance of the columns and resulted in a more stable load-displacement curve with lower strength degradations as compared with the un-strengthened ones. Additionally, it was found that the most effective method to increase the lateral strength and ductility is increasing the L angle thickness. On the other hand, increasing the steel jacket height also increases the lateral performance, however, it was identified that increasing the jacket height is effective only up to 1/3rd of the RC column height. Finally, the obtained results for each parameter were compared to study the behaviour of each component of the steel jacket towards lateral strength and ductility improvements.
