Published: December 2022

In this paper, an IoT based real-time monitoring and controlling system have been designed and developed for an eco-friendly aquaculture system namely a biofloc fish farm. Currently, technology has a vital role in improving aquaculture production which leads to attaining sustainable development. The microorganisms in the biofloc fish tank are utilized for detoxifying the toxic waste materials by recycling as well as transforming them into fish food e.g. protein cells. Hence, it not only manages good water quality in the biofloc system but also produces additional feed for the fish. Water quality monitoring of biofloc fish tanks is a significant aspect to guarantee a better environment for producing fish. This paper focuses on developing an IoT based device for biofloc fish tanks to monitor various water quality parameters as well as control water temperature and air pump. Using this device, users can monitor the water quality data received from sensors and control the actuators accordingly from any remote location through the graphical user interface (GUI).

Published: December 2022

Purpose: The safety of online contouring and planning for adaptive radiotherapy is unknown. This study aimed to evaluate the dosimetric difference of the organ-at-risk (OAR) according to the extent of contouring in stereotactic magnetic resonance image-guided adaptive RT (SMART) for pancreatic cancer.Materials and Methods: We reviewed the treatment plan data used for SMART in patients with pancreatic cancer. For the online contouring and planning, OARs within 2 cm from the planning target volume (PTV) in the craniocaudal direction were re-controlled daily at the attending physician's discretion. The entire OARs were re-contoured retrospectively for data analysis. We termed the two contouring methods the Rough OAR and the Full OAR, respectively. The proportion of dose constraint violation and other dosimetric parameters was analyzed.Results: Nineteen patients with 94 fractions of SMART were included in the analysis. The dose constraint was violated in 10.6% and 43.6% of the fractions in Rough OAR and Full OAR methods, respectively (p = 0.075). Patients with a large tumor, a short distance from gross tumor volume (GTV) to OAR, and a tumor in the body or tail were associated with more occult dose constraint violations—large tumor (p = 0.027), short distance from GTV to OAR (p = 0.061), tumor in body or tail (p = 0.054). No dose constraint violation occurred outside 2 cm from the PTV.Conclusion: More occult dose constraint violations can be found by the Full OAR method in patients with pancreatic cancer with some clinical factors in the online re-planning for SMART. Re-contouring all the OARs would be helpful to detect occult dose constraint violations in SMART planning. Since the dosimetric profile of SMART cannot be represented by a single fraction, patient selection for the Full OAR method should be weighted between the clinical usefulness and the time and workforce required.

Authors: Kim Dowook , Keam Bhumsuk , Ahn Soon-Hyun , Choi Chang Heon , Wu Hong-Gyun
Published: December 2022

Purpose: Nasopharyngeal cancer (NPC) has a higher prevalence of regional nodal metastasis than other head and neck cancers; however, level IB lymph node involvement is rare. We evaluated the safety and feasibility of level IB-sparing radiotherapy (RT) for NPC patients.Materials and Methods: We retrospectively reviewed 236 patients with NPC who underwent definitive intensity-modulated RT with or without chemotherapy between 2004 and 2018. Of them, 212 received IB-sparing RT, and 24 received non-IB-sparing RT. We conducted a propensity score matching analysis to compare treatment outcomes according to IB-sparing status. In addition, dosimetric analysis of the salivary glands was performed to identify the relationship between xerostomia and the IB-sparing RT.Results: The median follow-up duration was 78 months (range, 7 to 194 months). Local, regional, and distant recurrences were observed in 11.9%, 6.8%, and 16.1% of patients, respectively. Of the 16 patients with regional recurrence, 14 underwent IB-sparing RT. The most common site categorization of regional recurrence was level II (75%), followed by retropharyngeal lymph nodes (43.8%); however, there was no recurrence at level IB. In the matched cohorts, IB-sparing RT was not significantly related to treatment outcomes. However, IB-sparing RT patients received a significantly lower mean ipsilateral and contralateral submandibular glands doses (all, p < 0.001) and had a lower incidence of chronic xerostomia compared with non-IB-sparing RT patients (p = 0.006).Conclusion: Our results demonstrated that IB-sparing RT is sufficiently safe and feasible for treating NPC. To reduce the occurrence of xerostomia, IB-sparing RT should be considered without compromising target coverage.

Authors: Fatah Saiwan , Mustafa Arkan , Amin Shilan
Published: December 2022

In this paper, the Holling type Ⅱ functional response extended for n different species of prey and the dynamics of interactions between one predator species and its n different classes of prey are modeled. Positivity, boundedness and permanence of all solutions of the model are proved. An ecological threshold parameter for the predator free equilibrium point of the model is established. Local stability and global stability of the predator free equilibrium point are discussed. Furthermore, we also studied that the reproduction number R0 determines whether the equilibrium points are asymptotically stable or unstable. In addition, the model was solved numerically to confirm the analytical results.

Published: December 2022

The synchronization problem of delayed nonautonomous neural networks with Caputo derivative is studied in this article. Firstly, new neural networks are proposed by introducing variable parameters into known models, and the analytical formula of the synchronous controller is given according to the new neural networks. Secondly, from the drive-response systems corresponding to the above delayed neural networks, their error system is obtained. Thirdly, by constructing the Lyapunov function and utilizing the Razumikhin-type stability theorem, the asymptotic stability of zero solution for the error system is verified, and some sufficient conditions are achieved to ensure the global asymptotic synchronization of studied neural networks. Finally, some numerical simulations are given to show the availability and feasibility of our obtained results.

Published: December 2022

In Malaysia, food waste had become a significant problem. These recyclable natural waste resources are channeled towards the production of value-added products e.g. hydroxyapatite; which can be used as photo catalyst and many other applications. This study synthesized hydroxyapatite (HAP; Ca10(PO4)6(OH)2) powder from food waste using wet precipitation method. FTIR analysis was done on the synthesized hydroxyapatite powder, calcined samples and raw materials for each resource to study the functional group and the changes of composition in each sample. The Life Cycle Analysis (LCA) study done in this paper comprises of goal and scope definition, life cycle inventory, life cycle impact assessment as well as interpretation of data. Based on the results obtained, FTIR analysis shows that the synthesized powder is indeed hydroxyapatite based on the presence of important feature such as CO32- and PO43- and OH group and egg shell is proven to be the eco-friendliest resource as the production process contributed only 1% to environmental impact.

This paper presented an experimental and numerical study of functionally graded materials made by the permanent casting method and in three models with different mixing ratios between aluminum and zinc alloys (FGM1, FGM2, and FGM3) as in figure 1. In the permanent casting process, three models of the functionally graded material were produced and mechanical tests were conducted on them such as tensile and hardness tests, and the behavior of tensile strength, yield strength, elastic modulus, and fatigue was analyzed on them. The fatigue test was conducted at six levels of load and at room temperature. Simulations were carried out for the three models and a simulated fatigue test for the functionally graded material into the Ansys program. The results of the fatigue test showed an apparent effect of the different mixing ratios of the functional-grade material. As well as the numerical results were, close to the experimental results. There was an improvement in the fatigue life compared to FGM3, by 23% to FGM2. In addition, the fatigue life of the FGM3 of 11% higher than from the FGM1 model. In addition to that, which is important, the improvement in the fatigue life characteristics of the third type was 36% compared to the alloys from which the functionally graded materials were made.

Published: December 2022

In this paper, a simple and effective method was used to synthesize monodisperse metal Ruthenium nanospheres (Ru-HNSs), and the silicon dioxide (SiO2) nanospheres synthesized by Stober method were used as hard templates. The surface of SiO2 was double modified by γ-aminopropyltriethoxysilane (KH550) and salicylaldehyde, so that Ru3+ grew uniformly on the surface of modified SiO2 and reduced to form a stable and durable layer of Ru metal. Then the hard template SiO2 was corroded by chemical etching to obtain Ru-HNSs hollow spheres. The results show that the diameter of SiO2 microspheres was about 300nm, the wall thickness of Ru-HNSs was about 3nm, and the diameter was about 100nm.

The analysis of high temperature physical and chemical properties of molten salt system of aluminum electrolysis has guiding significance for practical production In this paper, the molecular dynamics calculation method was used to simulate the physical and chemical properties of 78%Na3AlF6-9.5%AlF3-5.0%CaF2-7.5%Al2O3 molten salt electrolyte system with Zr and B as additives at 1200K and standard atmospheric pressure. The effects of Zr and B elements on the radial distribution function, coordination number, diffusion coefficient, viscosity, and conductivity of electrolyte system were discussed in detail. The simulation results showed that Zr4+ weakened the connection between Al3+, while the addition of B3+ enhanced the interaction between Al3+, Na+, and F-. In the electrolyte system without impurities, the order of self-diffusion coefficient is Na+ > O2- > F- > Ca2+ > Al3+. And the addition of Zr4+ is conducive to the diffusion of ions in the system, while the addition of B3+ is not conducive to the diffusion of ions in the system. What’s more, the addition of Zr improves the conductivity of the system, while the addition of B reduces the conductivity of the system.

Published: December 2022

This study reports the synthesis of cellulose nanocrystals (CNC) sulfonation from the isolated cellulose nanofibers (CNF) of the Eichhornia crassipes stems. The crystallization of fibers was done by varying the time of sulfonation, 30 min (CNC30) and 60 min (CNC60), in 6M sulfuric acid. Scanning electron microscope images (SEM), and energy dispersive X-ray spectroscopy (EDS) revealed that the crystals have a grain flakey-like structure with the detected presence of oxygen, carbon, and sulfur (due to the sulfonation) atoms. Using Fourier transform infrared spectroscopy (FTIR), unique functional groups of CNCs were detected. Further, the X-ray diffraction (XRD) scans revealed that CNCs have a cellulose-Ib monoclinic unit cell structure with Miller indices (200) and (400). Additionally, results showed that CNC30 has 74.45% and CNC60 has 76.13% crystal index percent and a crystal thickness of 0.048 nm for CNC30 and 0.047 nm for CNC60. Lastly, d-spacing of CNC30 and CNC60 exhibited values of 3.26 Å and 3.20 Å, respectively. These results warrant further studies on future applications of the produced CNC from Eichhornia crassipes fibers.

Authors: Amoako Yaw A. , Van Eyssen Ann , Brink Anita
Published: December 2022

Background: 123I-Metaiodobenzylguanidine ([123I]mIBG) is the agent of choice to assess for presence of metastases and therapy response in patients with neuroblastoma.Aim: To assess [123I]mIBG scan results and outcome in patients with stage 4 neuroblastoma at our institution.Setting: Red Cross War Memorial Children’s Hospital.Methods: A retrospective review of baseline and follow-up [123I]mIBG scans of patients who presented between January 2001 and May 2015. The clinical follow up extended until October 2019. The association between the baseline and post-induction Curie score (CS) and overall survival (OS) were assessed.Results: Thirty-four patients with stage 4 disease were included. Twenty-two (65%) patients died. The median age at diagnosis for survivors was 15.5 months vs 39 months for those who died (Kruskal Wallis c2 = 4.63, p = 0.03). Neither the baseline CS nor the post-induction CS predict the outcome or duration of survival. The median OS for a baseline CS ≤ 12 and CS 12 was 19 and 26 months, p = 0.13. The median OS for a post-induction CS 2 and CS ≤ 2 was 28 and 26 months, p = 0.66.Conclusion: In this study, baseline, post-induction and reduction in CS did not predict OS in stage 4 neuroblastoma. Factors such as small patient numbers, less intensive treatment regimes, and possible poorly dedifferentiated disease have been identified for this finding.Contribution: In contrast to international studies the Curie score did not predict treatment outcome in the South African setting where the vast majority of patients are treated with OPEC/OJEC OPEC/OJEC (vincristine [O], cisplatin [P], etoposide [E], cyclophosphamide [C] and carboplatin [J]) chemotherapy.

Authors: Asif Hussain Khazi Syed , Kund Reddy Aluka Sundeep , Raju Mayani , Patnala Chandrashekhar
Published: December 2022

Background:

Older adults who sustain hip fractures usually have multiple comorbidities that may impact their treatment and outcome. This study aims to analyze the risk factors that contribute to falls in elders and analyze the effect of comorbidities on the outcome and the treatment decision-making in elderly patients with hip fractures.

Materials and Methods:

This cohort study was conducted on patients with hip fractures. We prospectively analyzed 140 cases of geriatric hip fractures who had undergone surgery. The Charlson Comorbidity Index (CCI) and American Society of Anesthesiologists (ASA) of each geriatric hip fracture patient were calculated based on data retrieved from the medical records. Clinical assessment was assessed using a modified Harris hip score during each visit.

Results:

The mean age of patients was 72.21 ± 12.2 years. The mean CCI was 1.02 ± 0.3, and ASA was 2.0 ± 0.53, and both were significantly associated with time-to-surgery (P < 0.001) and surgical treatment (P < 0.001). The length of hospital stay, duration of postoperative intensive care, and hospital expenses were associated with both CCI (P = 0.037) and ASA (P = 0.002). Greater the CCI and ASA, more chances of developing postoperative complications (χ2 = 15.724, P = 0.001). Delirium is the most common postoperative complication 15.7%, and pulmonary infection 11.4% is the most lethal complication.

Conclusions:

Patients with high CCI, ASA grading, and revision surgery are at high risk of developing postoperative complications, morbidity, and mortality. With efficient medical co-management of these patients, orthogeriatric care offers the best chance for a successful outcome.
TÜRKİYE CUMHURİYETİ MEVZUATINDA KAMU PESONELİ VE KAMU ZARARI
Authors: BOZPİNAR Cumali , ELMAS EROL Hülya
Published: December 2022

Türkiye Cumhuriyeti’nde kamu zararı kavramı muhtelif kanunlarda düzenlenmiştir. Bu durum hukuki bir sorun teşkil etmektedir. Bu çalışmada 657 ve 5018 sayılı Kanunlarda yer alan kamu zararı ve kişisel sorumluluk kavramları karşılaştırılarak uygulamada yaşanan sorunlara yönelik çözüm önerileri getirilmesi amaçlanmıştır. Çalışmada konuyla ilgili literatür taranmış ve elde edilen bulgular karşılaştırmalı olarak değerlendirildikten sonra bazı teorik çıkarımlarda bulunulmuştur. İlk sonuç, kamu zararından sorumlu tutulacak kimselerin sadece memur tanımına giren kimseler olmadığıdır. Kamu zararı söz konusu olduğunda, istihdam türü dikkate alınmaksızın kamu görevi yerine getiren ve kamu yetkisi kullananların tamamının kamu görevlisi sayılması gerekir. İkinci olarak, 5018 sayılı Kanunda yer verilen “kasıt, kusur ve ihmalen” kelimelerinin teknik bir içeriğe sahip olmayıp yalnızca müşterek ve müteselsil sorumluluğu bertaraf etmek için kullanıldığı düşünülmektedir. Bu sonuçlara bağlı olarak kamu zararı ve kişisel sorumluluğa ilişkin olarak Türkiye Cumhuriyeti mevzuatında çelişkiler bulunduğu söylenebilir. Şöyle ki kamu zararı ve kişisel sorumluluk hususlarında birden fazla düzenleme vardır. Bu nedenle çelişkiden uzak bir “kamu zararı ve kişisel sorumluluk” mevzuatının oluşturulmasının faydalı olacağı düşünülmektedir.

In this study, a shoal of bull rays, Aetomylaeus bovinus (E. Geoffroy Saint-Hilaire, 1817), around a sea-cage fish farm in Iskenderun Bay, Turkey is reported. Such an aggregation is probably due to ontogenetic shift but may also be a factor of reproductive process as some pregnant females were observed. The number of individuals recorded, in all more than 25, shows that the species is still present in the area but needs a conservation plan due to its k-selected life-histories and potential for extinction.

Dijital teknolojideki son gelişmelerle birlikte gerçekliğin büküldüğü, farklı görülerle yeniden tasarlanabildiği alanlar kurgulanabilmektedir. Bunlardan biri “Artırılmış Gerçeklik” olarak Türkçeye çevrilen “Augmented Reality (AR)”dir. Bilgisayar sistemleri ile düz yüzeyleri hareketlendirebilen, gerçek mekâna normalde olmayan/sanal görüntüleri bindirebilen, yeni katmanlar ekleyebilen bu teknoloji resim sanatına da yeni bir hareket alanı getirmiştir. Bu yeni hareket, fütürizmi resim sanatında daha geniş bir perspektifte yeniden yapılandırmıştır. Yirminci yüzyıl başlarındaki makineleşme ile birlikte yaşamın her alanına gelen hız ve dinamizm, resim sanatı odağına da yansıtmış fütürizm hareketi gündeme gelmiştir. Dijital çağ ise hızı ve dinamizmi fiziksel boyutların ötesine taşıyarak zaman ve mekân kavramlarını altüst etmiştir. Resimde fütüristik hareket de artırılmış gerçeklik ile birlikte fiziksel sınırlılıklarını aşarak dinamizmi göstermek ve hissettirmenin yanında bir de yaşatmaya başlamıştır. Resim sanatının artırılmış gerçeklik teknolojisi ile temas ettiği noktada devinim, yalnızca imge hareketi ile sınırlı kalmayarak sergilendiği alanlararasında da gerçekleşmektedir. Hatta etkileşim ve interaktivitenin eklenmesiyle izleyicinin de devindiği bir sanat oyunundan da söz edilebilir. Ayrıca AR özelinde de başka sanat dalları ve multimedya ile disiplinlerarası yeni bağlamlara yolculuk gerçekleşmiştir. Yeni gerçeklik teknolojilerinden AR birçok bakımdan resim sanatında fütüristik açıların güne ve geleceğe uyumlanmasına aracılık etmektedir.

Betimsel nitelik incelemesi olarak yapılan bu çalışmada resim sanatında fütürizme genel bir bakış atılacak, AR teknolojisi açıklanacak, artırılmış gerçekliğin resim sanatında kullanımı örneklerle betimlenecek, fütürizm bağlamındaki yeri tartışılacaktır.

Derechos humanos, universales
Authors: Ruiz Rodríguez Virgilio
Published: December 2022

El debate en torno a la universalización de los derechos humanos está enmarcado en el dilema real: unidad en la diversidad o la diversidad que niega la unidad. El problema radica en esto: o se acentúa la unidad que subsume a la diversidad, o se acentúa ésta para negar aquélla. Todos los seres humanos somos iguales, no hay muchas, ni siquiera dos naturalezas humanas, sino una sola, encarnada en los distintos seres humanos. Con esta última afirmación, sostenemos que aunque somos diferentes, somos también iguales; con lo cual afirmamos que los derechos humanos son universales. Reconocer las diferencias para tratarnos como iguales.
Hallazgo, dolor y olvido. Tensiones del recuerdo a través de la dimensión mental de medios de memoria digitales. El caso de Archivos de la Represión
Authors:   Universidad Autónoma Metropolitana, Ortega Vázquez Guillermo Salvador
Published: December 2022

Los archivos digitales han reconfigurado las formas de difusión y aproximación hacia los acervos que resguardan documentos sobre violaciones a los derechos humanos. En el caso mexicano, es hasta 2018 que surge uno de los primeros dispositivos digitales que almacena documentos relacionados con violaciones graves a derechos humanos, se trata de los “Archivos de la Represión” (https://archivosdelarepresion.org/). Proyecto creado por Artículo 19, Comisión de la Verdad de Guerrero y El Colegio de México, cuyo objetivo es contribuir al derecho a la verdad y memoria del periodo de represión y violencia sistemática por parte del Estado entre 1950-1980 en México. El artículo que se presenta a continuación observa al archivo digital como un medio de memoria, concepto desarrollado por Astrid Erll (2011). Pone especial atención a la dimensión mental de este medio de memoria, constituida por todos aquellos esquemas que son específicos de la cultura y los códigos colectivos que hacen posible y que marcan el recordar común a través de la transmisión simbólica. Pretende responder a una pregunta central: ¿Cuáles son las representaciones mentales sobre el pasado represivo que construyen los familiares de víctimas y los usuarios del archivo digital “Archivos de la Represión”?
#MarielleVive y el MBL Crimen, conflicto y sociedad digital
Authors:   Freie Universität Berlin, Pacheco Wegmann Daniel
Published: December 2022

Este artículo analiza algunos de los espacios digitales del Movimento Brasil Livre (MBL), uno de los representantes de la llamada “nueva derecha” brasileña, centrándose en las acciones del grupo en la proliferación de noticias falsas con motivo del asesinato de la política brasileña Marielle Franco en marzo de 2018. La investigación relaciona el tema con la noción de "esfera pública emocional" (Lange 2014) y las consideraciones de Hine (2014) sobre los “eventos mediáticos”. Partiendo de la página oficial del MBL y de su perfil de Facebook, la investigación explora tanto la forma en que el grupo constituye su narrativa política en dichas plataformas, como algunas interacciones sociales que dialogaran con ellas a partir de la difusión de rumores. Observaciones etnográficas digitales se sumaron al análisis crítico del discurso y de los fenómenos visuales en Internet, tratando de comprender los mecanismos de "reconocimientos" (Barbero 2012) y "autoproducciones" (Haynes 2016) que informaron el debate público digital generado por el tema. Las intervenciones online se configuraron como una fuente relevante para investigar las prácticas simbólicas y dinámicas culturales de sus actores, y permitieron reflexionar sobre el ambiguo papel político de los medios digitales.

Ethnographicity of a National Political Body
Authors: Kyrchanoff Maksym W.
Published: December 2022

The author analyzes cultural tactics and strategies aimed at the nationalization of the body in public, political and cultural spaces. The images of the national, nationalizing and nationalized body in modern cultures and spaces of memory are analyzed. The purpose of the study is to analyze visual strategies for the nationalization of the body in the intellectual histories of Central and Eastern Europe in the second half of the 19th and early 21st centuries. Geographically, the article is limited to the analysis of the politically motivated nationalizations of corporality in the greater Eastern and Central European cultural contexts. The chronological and geographical framework is motivated by the need to detect both continuity and discreteness in the nationalization of the body in the political cultures of the region, as well as general trends and regional characteristics of cultural and political practices, the author analyze in the article. The article shows that the historical and cultural prerequisites for the nationalization of the body developed in the 17th and 18th centuries within the framework of the “high” political culture, which operated with the images of great ancestors, projecting onto clothes as an element of socially acceptable physicality. The author believes that by the beginning of the 21st century, the nationalization of physicality express itself in several strategies, including the visualization of traditional ethnicity and the actualization of elements of modern political culture, which combine the visualization of biological signs of physicality in their combination with elements of a personality cult.

Teacher’s Attitude towards Inclusive Education in Tanzanian Primary Schools: A Case of Iringa District
Authors: Z. Nyoni Kristofa
Published: December 2022

The study sought to establish teacher’s attitude towards inclusive education in Tanzanian primary schools: A case of Iringa District using the qualitative approach and a case study design. The population of the study was primary school teachers of whom a total sample of 36 respondents was selected in the following distribution: 30 primary school teachers and 6 head teachers. Thirty (30) primary school teachers were selected through simple random sampling while three (6) heads of schools were purposely selected. The study employed semi-structured interview and focus group discussion (FGD) as instruments to obtain data which was analyzed thematically. The study established that while school heads had positive attitude toward inclusive education, teachers had a limited understanding of what inclusive education actually is as they considered it as simply combining disabled learners in the mainstream classes. Teachers had negative attitude toward inclusive education as they believe that having a mixture of students with behavioral challenges and learning disabilities makes the class not easily manageable. Based on the conclusions, it is recommended that the government should conduct capacity building seminars and workshops in which teachers can gain knowledge and appropriate skills on how to have challenged learners included in the mainstream classrooms. Finally, administration of schools need to ensure availability of appropriate teaching and learning resources for inclusive classrooms so that learners of various kinds may be met at the points of their needs during the teaching and learning sessions in the mainstream classrooms.

Published: December 2022

The study sought to establish determinants of religious tolerance in Ede Community, Osun State, Nigeria using the descriptive survey design. The study population was 159, 866 people of Ede community based on the available latest census (Osun State, 2022) whereas a sample size of 420 was used for this study based on the Fisher’s formula. Data was collected through a questionnaire. Simple percentage analysis was used for analysis and chi-Square test was used for the bivariate analysis of the study. Each respondent was informed about the study before his or her written consent was obtained. Furthermore, respondents were told that they could decline their participation at any point in time in the course of data collection. However; they were encouraged to respond to all the items as they would only be used for research purposes. The study established a relatively high level of religious tolerance in Ede in spite of the religious diversity of its population. Ede people were generally open to learning about other religions apart from their own. They appreciated the socioeconomic values added by various religions in the community which made it possible to tolerate religious otherness. The study recommends periodic inter-religious dialogues and programs in Ede. Government and non-governmental agencies should be intentional about promotion of religious tolerance through formal educational institutions and media. Information about different religions and what they stand for should be disseminated to public so that people will be more informed about other religions in order that they may not engage in acts of religious intolerance out of misinformation about other religions.
