Enhancing Rice Nutrient Deficiency Classification using Capsnet with Contextual Attention Routing
Authors: Brindha K. , Amudha M.
Published: June 2023

Rice, being a widely grown food crop, often suffers from nutrient
imbalances, hindering its production, which suffers from a lack of
certain nutrients like potassium, nitrogen, and phosphorus. Identifying
the potential nutrient deficiency in the rice crop can pose a
challenging task because the leaves of rice plants affected by these
nutritional shortages may have disorders such as colour and shape
changes. The classification of nutrient deficits can be done visually by
examining the colour and shape of the leaves. However, it is expensive,
time-consuming, and requires greater expertise. To tackle this issue,
this work proposes a computer vision-based deep learning approach called
CAR-Capsnet, an enhanced version of the capsule network (Capsnet) that
utilises contextual attention routing (CAR) for classifying nutrient
deficiencies in rice crops. The dataset required for training and
evaluation is obtained from the freely available Kaggle data repository.
Pre-processing techniques, such as the Wiener filter and adaptive Otsu
segmentation, are applied to the dataset. Unlike traditional routing
approaches, CAR-Capsnet utilises contextual attention routing to improve
the model’s capability to handle complex visual features and patterns
associated with nutrient deficiencies in rice crops. In the evaluation,
the proposed model’s performance is compared with two other existing
models, CNN and the original Capsnet. Experimental results demonstrate
that CAR-Capsnet outperforms both models, achieving a testing accuracy
of 97.1% and exhibiting superior performance compared to the baseline
models. Additionally, comparing the classifier’s results with previous
research findings confirms that the proposed CAR-Capsnet model is
superior to alternative approaches in classifying nutrient deficiencies
in rice crops.
Air-Sea CO$_2$ Fluxes Localized By Topography in a Southern Ocean Channel
Authors: Youngs Madeleine K. , Freilich Mara A. , Lovenduski Nicole Suzanne
Published: June 2023

Air-sea exchange of carbon dioxide (CO$_2$) in the Southern Ocean
plays an important role in the global carbon budget. Previous studies
have suggested that flow around topographic features of the Southern
Ocean enhances the upward supply of carbon from the deep to the surface,
influencing air-sea CO$_2$ exchange. Here, we investigate the role of
seafloor topography on the transport of carbon and associated air-sea
CO$_2$ flux in an idealized channel model. We find elevated CO$_2$
outgassing downstream of a seafloor ridge, driven by anomalous advection
of dissolved inorganic carbon. Argo-like Lagrangian particles in our
channel model sample heterogeneously in the vicinity of the seafloor
ridge, which could impact float-based estimates of CO$_2$ flux.
Bed expansion in turbulent bed contactor: Experiments and prediction
Authors: Bensebia Bensaber , Chaouche Fatma-Zohra , Bensebia Ouahida , Moustefaï Soumia
Published: June 2023

In this work, turbulent bed contractor (TBC) hydrodynamics have been studied in terms of bed expansion (Hd/Hst) using a particular approach to predict this important property for the design of such equipment. The study is based on 1604 sets of experimental data on the bed expansion, obtained by varying the operating variables (gas velocity, liquid spray, packing characteristics, static bed height, and free opening of the supporting grid). The prediction of the bed expansion necessitates the estimation of gas and liquid holdups. To achieve this, we employed a variety of correlations derived from existing literature, comprising six equations for gas holdup and twenty equations for liquid holdup estimation. Out of a total of 120 cases, bed expansion was estimated, and the accuracy of the model was evaluated by calculating the mean absolute error in percentage (MAPE), root mean square error (RMSE), correlation coefficient (?XY), and explained variance (VECV). This study identified suitable correlations for gas and liquid holdups, leading to predictions with acceptable errors. Furthermore, statistical analysis was employed in a subsequent phase of the study to determine the most appropriate correlations for predicting bed expansion among those proposed by various authors.
An alternative proof of the Sombor index minimizing property of greedy trees
Authors: Damnjanovic Ivan , Stevanovic Dragan
Published: June 2023

Recently, Gutman defined a new graph invariant which is named the Sombor
index SO(G) of a graph G and is computed via the expression SO(G) = ?u~v?
qdeg(u)2 + deg(v)2, where deg(u) represents the degree of the vertex u in G
and the summing is performed across all the unordered pairs of adjacent
vertices u and v. Damnjanovic et al. have implemented an earlier result
obtained by Wang in order to show that, among all the trees TD that have a
specified degree sequence D, the greedy tree must attain the minimum Sombor
index. Here we provide an alternative proof of this same result by
constructing an auxiliary graph invariant named the pseudo-Sombor index and
without relying on any other earlier results.

Authors: Kular Kamil , Skrzyński Marcin
Published: June 2023

The note concerns the commutativity of associative rings (possibly nonunital)
endowed with a derivation. Our focus is on ?-prime rings. We give a new
proof of Hirano and Tominaga?s result that a ?-prime ring is commutative
whenever the derivation ? is nonzero and commuting on a nonzero two-sided
?-ideal. We also provide some further generalizations of Herstein?s
classical theorem on a prime ring admitting a nonzero derivation with
commutative range.

Published: June 2023

La condición de disminuir el impacto negativo en el medio ambiente, y en especial en las fuentes de agua naturales, causado por las industrias, justifica que el tratamiento de las aguas industriales sea un proceso de vital importancia dentro de las actividades de funcionamiento de las empresas. Es por esto que se propone como objetivo en esta investigación, la utilización de quitosano como coagulante y floculante, para tratar las aguas industriales generadas en los procesos de producción de pintura y pegamento de una empresa del ramo, con el fin de proponer un proceso ambientalmente sostenible. Las evaluaciones de indicadores relacionados con el tratamiento de aguas industriales, haciendo uso del quitosano para promover el proceso de coagulación y floculación, permiten inferir que el proceso es acertado, y los valores obtenidos de pH, demanda química de oxígeno (DQO), sólidos totales disueltos (STD) y sólidos totales suspendidos (STS) obtenidos muestran que son aptas para ser desechadas en la red cloacal interna, además de cumplir con las regulaciones establecidas en Venezuela, pues se obtienen aguas postratamiento con valores de pH entre 6,8-7,5, una reducción del DQO de alrededor del 85 %, y STD y STS de aproximadamente 90 %, que reducen considerablemente los efectos negativos de los diversos componentes involucrados en los procesos productivos de la empresa.
Administration of Oxycodone Hydrochloride by Target Controlled Infusion - Does the Timing Matter?
Authors: Ramstrøm Maj Jorunn R. , Hjelmaas Catherine , Dalen Ingvild , Eskeland Arild
Published: June 2023

Background: In spite of long-term clinical experience with oxycodone hydrochloride/OxyNorm (OH), analgesic concentrations of OH in acute postoperative pain management have not been established. There are assumably different opinions regarding intraoperative timing of OH administration among anaesthesiologists and nurse anaesthetists, hence different practices.
Aim: The aim of the study was to determine to which extent intraoperative timing of OH administration affects the need for postoperative OH during target-controlled propofol and remifentanil infusion (TCI) for patients undergoing laparoscopic cholecystectomy.
Method: Anesthetic and postoperative journals from 100 patients were included in this retrospective observational study. Patients in category 1 (n = 20) received OH towards the end in addition to the introduction/maintenance of TCI. Patients in category 2 (n = 66) received OH in the beginning/during the maintenance of TCI, but not towards the end. Patients in category 3 (n = 14) received OH only towards the end of TCI. Multiple regression models were used to analyze the data.
Result: Mean total postoperative doses of OH and standard deviations (SD) were 4.7 (3.1), 6.9 (5.1) and 4.7 (3.4) mg for patients in categories 1–3, respectively; with an overall p-value for equality of group means of 0.032. Adjusting for age, gender, weight, operating time and medications given during operation did not affect the results substantially (p = 0.012). In total during the per- and postoperative course, observed means (SD) of OH administered were 11.0 (2.9), 12.1 (5.5) and 9.0 (3.5) mg for patients in categories 1- , respectively (p = 0.039). The estimated group differences were only slightly affected by adjusting for patient and operational variables, however the result was no longer statistically significant (p = 0.057).
Conclusion: Our retrospective analysis suggested that intraoperative timing of OH administration affects the need for OH postoperatively after laparoscopic cholecystectomy with TCI anaesthesia. To reduce the total amount of OH, it may be beneficial to administer OH only towards the end of anaesthesia.

Authors: Rivera-Mejia José , Medina-Rodríguez Vicente , Molinar-Solís Jesús Ezequiel
Published: June 2023

El diseño de sistemas de monitoreo y/o control se basa en modelos matemáticos en el tiempo t, que implican ecuaciones diferenciales y transformadas de Laplace para su solución. Al asociar estos modelos con sistemas discretos y al usar microcontroladores o computadoras para digitalizar estos sistemas, se hace necesario el uso de la Transformada-z. Esta última requiere que se conozca el tiempo de muestreo utilizado, para que todos los modelos concuerden en sus resultados.

            El presente trabajo muestra un método práctico para determinar el tiempo de muestreo. Se utilizó el kit de desarrollo ESP-32-S2 y una red con una resistencia y un condensador. Mediante un programa en lenguaje C/C++ y un osciloscopio, se midió el tiempo de muestreo. Se realizaron experimentos para diferentes condiciones de operación del sistema de adquisición de datos, registrando el voltaje del condensador en respuesta a una alimentación escalón unitario. Los resultados reales se compararon gráficamente con los resultados en t, s y z, y se calculó el error entre la respuesta en t y los resultados prácticos.

            Esto demostró que el método propuesto genera una buena medida del tiempo de muestreo y que los resultados de los modelos en todos los planos concuerdan con los obtenidos en la práctica. Con esto, esperamos motivar a estudiantes y profesionales a aplicar las matemáticas en el diseño de sistemas digitales, fomentando el uso de herramientas de simulación que permitan el desarrollo de sistemas más rápidos y eficientes. Además, buscamos fortalecer trabajos relacionados con sistemas embebidos, sensores inteligentes, la Internet de las cosas y la industria 4.0.

Published: June 2023

This study investigates how changing environmental governance in Banda Aceh City can benefit from public participation. The secret to improving environmental governance is figuring out how to involve the public, businesses, and government in the process. The interaction and influencing factors among enterprise pollution control, government oversight, and public engagement are examined using evolutionary game theory, and an empirical study is conducted using data from Banda Aceh City from 2017 to 2021. The findings of the study demonstrate that government oversight has a favorable impact on environmental governance and can motivate businesses to aggressively reduce pollution. The income and cost of businesses limit the impact of government regulation, hence it is necessary to increase the fines for passive pollution control. Enhancing the government's reputational damage can also effectively encourage environmental oversight activity on the part of the government. Three industrial wastes are substantially better governed when the public participates, and the cost and psychological advantages of involvement have a strong correlation with public enthusiasm. To some extent, public participation can take the place of governmental control. Environmental governance benefits from interactions between the public and the government. The study's findings will enhance environmental governance performance and public satisfaction while assisting in the development of an efficient system.

Financial Feasibility Study of Carbon Capture, Utilization, and Storage Project in West Java, Indonesia
Authors: Amelinda Adanya T. , Soekarno Subiakto
Published: June 2023

Following The Paris Agreement, Indonesia submitted an Enhanced Nationally Determined Contribution with an emission reduction target of 31,89% unconditionally or 43,20% conditionally. Indonesia envisions to reach net zero emission by 2060 or sooner. Contributing approximately a third of the carbon emission nationally, the decarbonization of the energy sector plays a big role in the ENDC pathways. From the oil and gas subsector, one of the programs designated to reduce their greenhouse gas emission are CCS (Carbon Capture and Storage) and CCUS (Carbon Capture, Utilization, and Storage). In oil and gas upstream industry, CCUS is a combination of technologies that involves sequestering carbon dioxide (CO2) from oil and gas upstream activities, utilize it as an enhanced oil recovery to increase liquid production before storing it permanently underground. However, the development of CCUS is filled with challenges. Other than the technical challenge of CCUS, the project is deemed to be too expensive and unable to generate a positive return for the project owner. Carbon trading is one of the mechanisms intended to provide added revenue for CCUS project. Using the carbon offset and trade mechanism, entities that conduct emission-reducing activities receive credit for the amount of emission reduced. The carbon credits can be sold in the market to other companies that need it. This research aims to determine whether carbon trading could increase the profitability of a CCUS project owned by an oil and gas company located in West Java, Indonesia. The project consists of capturing CO2 generated from natural gas purification, transporting it via pipeline to a nearby depleted oil field where the CO2 is used as an enhanced oil recovery, and storing it permanently underground.
“We’re always playing ghosts”. A hauntological reading of Winsome Pinnock’s drama Rockets and Blue Lights
Authors: Singer Christoph
Published: June 2023

The Zong-massacre of 1781, when 133 enslaved women, men and children were thrown overboard a slave ship by British crewmembers, has turned into a central event in the discussion and commemoration of the slave trade. Literary texts from poems such as David Dabydeen’s Turner and NourbeSe Philip’s Zong! to novels like Fred D’Aguiar’s Feeding the Ghosts and Lawrence Scott’s Dangerous Freedom (2021) probe different ways of approaching the silences surrounding the crime as well as the ensuing court cases in which the slave ship’s owners demanded compensation for their ‘lost property,’ rather than facing charges of murder. In this article, I will discuss Winsome Pinnock’s Rockets and Blue Lights (2021), which not only revolves around the Zong-massacre but approaches the slave trade by employing discourses and images related to the theoretical concepts of hauntology. Pinnock deconstructs hegemonic historiographies of the slave trade and counters British postcolonial amnesia by means of, what I would like to call, spectral temporalities. These temporalities are presented as non-linear and a-chronological. Full of revenants of the past, in Jacques Derrida’s terms, the play’s trans-temporal plots address the gaps and silences in British Histories. Firstly, this article will outline the Zong massacre and its thematic resurgence in contemporary literature and culture. Secondly, I will read Pinnock’s play with theories of hauntology and spectral temporality. Thirdly, this article will discuss how Rockets and Blue Lights explicitly addresses and dramatizes this paradox double-nature of the presence of the past on the theatre-stage.
Secrets, leaks and the novel. Writers, British intelligence and the public sphere after World War Two
Authors: Morrison Jago , Burton Alan
Published: June 2023

This article makes a pioneering effort to explore the relationship between spy fiction, intelligence and the public sphere in Britain after World War Two. The secret British achievements of code-breaking, atomic science and deception in the World War of 1939–45 were outstanding. Similarly, the British contribution to spy fiction in the twentieth century has been seen as exceptional. However, the complex interconnections between the history and fictions of intelligence in the post-war decades have never been closely examined. This is a period during which the British state aggressively sought to suppress memoirs and histories written by wartime secret warriors. Other writers who chose to disclose aspects of their intelligence work through the idiom of spy fiction, however, met with a rather different response. In this period, we argue therefore, the relatively unpoliced spy story emerged as a tolerated form of leakage for wartime secrets. The public reputation of the British security establishment underwent a serious decline in the post-war years, in the wake of successive scandals and defections. British intelligence made a number of attempts to repair its battered image in this era, for example publicising a key case involving a Soviet double agent working for the West. However, fiction remained a key terrain on which an ongoing battle for the reputation of British intelligence continued to be fought out. From the early 1960s a significant new form began to emerge: the ‘New Realism’ of John le Carré. Widely accepted as an authentic image of the British intelligence ‘circus,’ these stories portrayed the British secret state in a strikingly harsh and revealing light. Working directly in response to le Carré, writers like John Bingham sought to counter with an altogether more positive impression of secret service. Again, the spy novel provided a key platform on which struggles over the public image of intelligence were fought out. In this way the essay draws together the history and fictions of the post-war decades to reveal an intimate correspondence between writers, secret service and the public understanding of intelligence.
Authors of everyday life. Towards learning with literary learner texts in English language education
Authors: Becker Daniel , Matz Frauke
Published: June 2023

In the digital realm of the 21st century, the production and distribution of literature has changed drastically; writing literary texts is no longer a privilege of professional authors and publishers but has transformed into a participatory practice, with non-professional writers sharing their own literary narratives via social media platforms. This digital practice has become particularly relevant among teenagers and young adults as they increasingly use the opportunity of producing and sharing their own literary texts as a means of negotiating their identities and the social environments around them. Literature, thus, enables teenagers to participate in society by voicing their own personal and social concerns. Given their value in the context of engaging in these meaning-making processes on the one hand, and the role and importance of English as one of the lingua francas in digital realms on the other, these digital literary practices also need to be reflected in contemporary English language education (ELE). However, this hardly seems to be the case so far. Although literary texts still play a very prominent role, particularly in English as a foreign language (EFL) classrooms in Germany, current approaches to learning with literature still appear to perceive learners as recipients of professional literary texts, while production-oriented perspectives on teenagers as authors of their everyday lives, which go beyond post-reading creative tasks, seem to hold a most marginal position. Thus, digital texts written by learners (i.e., literary learner texts) are hardly considered as source texts. This theoretical contribution argues that contemporary practices of learning with literature need to be complemented by also focusing on literary works created by learners on multiple levels of classroom action. Drawing on interdisciplinary concepts, it explores the relevance of this focus in detail and makes first suggestions for framing literature classrooms based on literary learner texts.

Authors: Sasidharan Priyanka , Chidambaram Yoganathan , Kumar Bhargavi , Velammal Petchiappan , Kumar Sujith
Published: June 2023

Objective. Hypothyroidism is a syndrome characterized by clinical manifestations associated with thyroid hormone deficiency. The thyroid hormone plays a pivotal role in the hematopoietic system and stimulates precursors of erythropoietin gene expression. Therefore, anemia is a common clinical manifestation in hypothyroid individuals. The goal of this study was to carry out a prospective analysis of the prevalence of anemia, its types, and the etiology behind the differing anemia morphology among hypothyroid patients.

Methods. The study was conducted with a sample size of 100 patients suffering from hypothyroidism. The methodology of the study included a questionnaire and consent filling for general information followed by a complete blood test for assessment of blood count, peripheral smear, FT3/FT4 (free triiodothyronine/thyroxine), anemia profile, vitamin B12, folate, LDH (lactate dehydrogenase), reticulocyte count, and thyroid stimulating hormone (TSH).

Results. The results of the study are in line with the previous studies and showed severe anemia and prevalence among women of reproductive age. Microcyte hypochromic anemia was found to be the most common type of morphological anemia, which was validated with low hemoglobin (Hb) levels, vitamin B12, FT3, and FT4. Additionally, TSH showed a positive correlation with reticulocyte count, LDH, and Hb in Pearson’s correlation test.

Conclusion. The study summarizes the need to investigate the underlying etiological agent responsible for better therapy and management of hypothyroidism and anemia suggesting also the use of oral iron supplements along with levothyroxine therapy.

Authors: Rezkallah Emad , Elsaify Andrew , Martin Victorino , Viva Laura , Nag Sath , Green Barnabas , Cheesman Matthew , Elsaify Wael
Published: June 2023

Objective. Pheochromocytomas and paragangliomas are rare neuroendocrine tumors that arise from the chromaffin cells of the adrenal medulla or extra-adrenal tissues. These tumors are characterized by an excessive secretion of catecholamines, which are responsible for the clinical manifestation of the disease. Although most of these tumors are sporadic, underlying genetic abnormalities may be present in up to 24% of the cases. A succinate dehydrogenase subunit B (SDHB) mutation represents one of the rare presentations of the disease. In this study, we represent a rare case of pheochromocytoma associated with SDHB mutation.

Methods. We performed a retrospective review of our case in addition to reviewing the available literature on the same topic.

Results. A 17-year-old patient presented with sustained hypertension. Clinical, laboratory, and radiological evaluations confirmed the diagnosis of catecholamine-secreting tumor. Laparoscopic adrenalectomy was performed. Histopathological and genetic testing confirmed a pheochromocytoma associated with SDHB mutation. No recurrence was detected on two-years of follow up.

Conclusion. Pheochromocytoma associated with SDHB mutation is a rare presentation. Genetic testing for suspecting cases is essential to help to establish the appropriate follow-up plan.

Kesehatan rongga mulut berpengaruh terhadap kualitas hidup serta status gizi masyarakat sebab rongga mulut merupakan organ terluar pada sistem pencernaan yang berinteraksi langsung dengan lingkungan. Berdasarkan Riset Kesehatan Dasar RI Tahun 2018, permasalahan rongga mulut di Indonesia mencapai 57,6%. Kesehatan rongga mulut penting diperhatikan untuk menghindari timbulnya permasalahan pada kesehatan, seperti infeksi oleh bakteri patogen di mulut. Salah satu upaya menjaga kesehatan mulut adalah dengan menggunakan obat kumur. Namun, obat kumur dengan bahan aktif kimia sintetis yang dalam jangka panjang berisiko pada kesehatan. Maka dari itu, perlu dikembangkan sediaan obat kumur berbahan herbal dengan sistem penghantaran obat nanopartikel yang mudah menyebar. Daun keji beling (Strobilanthes crispus) adalah satu tanaman lokal yang berpotensi sebagai antibakteri di rongga mulut. Kajian pustaka ini bertujuan untuk memaparkan formulasi obat kumur herbal berbasis nanopartikel perak dengan ekstrak daun keji beling sebagai bahan aktif antibakteri. Metode yang digunakan dalam penelusuran pustaka, yaitu review naratif terhadap berbagai literatur ilmiah. Berdasarkan hasil kajian pustaka, daun keji beling berpotensi sebagai antibakteri dengan adanya kandungan senyawa bioaktif berupa flavonoid, alkaloid, saponin, butirolakton, asam heksanadioat, dan asam asetat. Ekstraksi maserasi daun keji beling dengan menggunakan etanol menghasilkan senyawa polifenol yang berperan dalam sintesis nanopartikel perak. Nanopartikel perak ekstrak etanol daun keji beling digunakan sebagai bahan aktif dalam formula obat kumur. Di samping itu, gliserin, sakarin, mentol, natrium benzoat, peppermint oil, tween 80, asam benzoat, citrus oil, dan natrium bikarbonat dapat digunakan sebagai eksipien yang menunjang formula obat kumur herbal.

Authors: Ni Putu Intan Satya Dewi  , Sagung Chandra Yowani
Published: June 2023

Luka adalah keadaan terjadi putusnya jaringan tubuh yang menyebabkan fungsi tubuh terganggu dalam melakukan aktivitas. Luka apabila tidak diobati sesuai dengan pengobatan yang benar, maka rentan menyebabkan waktu penyembuhan luka menjadi lama. Ekstrak daun pegagan dan ekstrak daun sirih merah adalah kombinasi bahan aktif yang berpotensi dikembangkan dengan tujuan agar efektivitas penyembuhan luka meningkat, karena mengandung berbagai konstituen yang memiliki indikasi untuk mempercepat proses penyembuhan luka serta antibakteri. Namun, marker utama dari kedua zat aktif ini memiliki kelarutan yang buruk. Self-Nanoemulsifying Drug Delivery System (SNEDDS) adalah suatu sistem penghantaran obat yang stabil sehingga sistem ini mampu membuat kelarutan dan bioavailabilitas zat aktif menjadi meningkat. Kecilnya ukuran partikel zat aktif akan meningkatkan luas permukaan kontak antara zat aktif dan pelarut, maka hal ini akan menyebabkan absorpsi, laju disolusi, serta kelarutan zat aktif meningkat. SNEDDS dibuat dengan mengkombinasikan ekstrak daun pegagan dan daun sirih merah sebagai bahan aktif dengan surfaktan dan ko-surfaktan dengan perbandingan 1: 6: 3 (1 mL capryol 90 (fase minyak), 6-mL tween 20 (surfaktan), dan 3-mL PEG 400 (ko-surfaktan)) lalu diformulasikan ke dalam sediaan gel dengan penggunaan karbopol sebagai gelling agent. Tujuan penelitian ini adalah untuk menambah wawasan serta memperbaharui pengetahuan masyarakat terkait kandungan kimia daun pegagan dan daun sirih merah sebagai agen terapi penyembuhan luka, beserta teknologi pembuatan SNEDDS-gel guna memperoleh hasil terbaik. Produksi agen terapi penyembuh luka berbahan dasar kombinasi kedua ekstrak ini dengan bentuk sediaan SNEDDS-gel berpsotensi dikembangkan menjadi produk herbal fungsional yaitu sebagai agen penyembuhan luka.
