Published: June 2024

We propose a modified branch-line coupler composed of the open stubs and stepped impedance lines. This structure allows the second harmonic suppression and size reduction. We present the steps to transform from a conventional branch-line coupler to the proposed structure using equivalent circuits and derive the generalized design formulas. From the results analysis of the design sample, we demonstrate the validity of the derived formulas. The fabricated branch-line coupler provides more than 30 dB the second harmonic suppression and about 30 % size reduction compared to a conventional branch-line coupler.

A moving water mass generates force which is exerted on its moving path. Cyclone generated storm surge or earthquake generated tsunami are specific examples of moving water mass generated force along the coasts. In addition to human lives, these moving water masses cause severe damages to the coastal infrastructure due to tremendous force exerted on these structures. To assess the damage on these infrastructures, an essential parameter is the resultant force exerted on these structures. To evaluate the damages, there is hardly any quantitative method available to compute this force. In this paper we have developed a semi-analytical model, named as Dynamic Force Model (DFM), by using Variational Iteration Method to compute this force. We have derived the governing equation on the basis of Saint-Venant equations which are basically 1D shallow water equations derived from the Navier-Stokes equations. DFM is verified, calibrated, validated, and applied in Bangladesh coastal zone to compute dynamic thrust force due to tropical cyclone SIDR.
Performance Analysis of MPBC with PI and Fuzzy Logic Controllers Applied to Solar Powered Electric Vehicle Application
Authors: Bodapati Rakesh Babu , Srinivas R. S. , Rao P. V. Ramana
Published: June 2024

One of the more complicated cases is managing the energy between multiple power sources that are utilized to power electric cars (EVs). Power management is often carried out following the load requirements of electric vehicles. By considering the speed and current values of the motor a novel controller is modeled named as Measurement of parameter-based controller (MPBC) which is used to obtain the smooth transition between two passive energy sources battery and Supercapacitor (SCap). Further, the proposed MPBC is combined with fuzzy logic (FLC) and proportional-integral (PI) controllers, forming two different hybrid controllers named MPBC+FLC and MPBC+PI, utilized to attain proper power management. The main function of traditional controllers FLC/PI is to generate the pulse signals to the switches present in the bidirectional converters at both battery and SCap end. On the other hand, the MPBC is utilized to control the pulse signals based on the current and speed values of the electric motor. Futcher's final MATLAB/Simulink model is built with the proposed control technique with two hybrid controllers by considering different power-generating conditions of the PV array, to know the effectiveness of the individual model.
Inteligencia Artificial, decisiones administrativas discrecionales totalmente automatizadas y alcance del control judicial: ¿indiferencia, insuficiencia o deferencia?
Authors: Ponce Solé Juli
Published: June 2024

El objeto de este artículo se centra en las posibilidades y límites de la adopción totalmente automatizada de decisiones administrativas discrecionales, el papel de la supervisión humana y el alcance e intensidad del control judicial de dichas decisiones. El estudio se detiene brevemente en la explicación de algunos conceptos esenciales vinculados a la IA para clarificar su uso en este análisis. Entre ellos, se realiza un breve análisis del concepto tradicional de discrecionalidad administrativa en España, poniendo de relieve su falta de profundidad y la necesidad de repensarlo a la luz de la buena administración. A partir de aquí, se abordan cuáles son los límites jurídicos de la IA y cómo deberían conducir a evitar su uso para la automatización total del ejercicio de potestades discrecionales, en el estado actual de la técnica. Esa limitación conduce a lo que se denomina una reserva de humanidad, que se desarrolla a continuación.  Finaliza el análisis exponiendo la adaptación de las técnicas de control judicial al ejercicio de potestades administrativas con IA, los posibles problemas de indiferencia e insuficiencia que puede tener dicho control judicial y el nivel de intensidad de control judicial que debiera desarrollarse.
Deferencia y tribunales internacionales de derechos humanos
Authors: Iglesias Vila Marisa
Published: June 2024

Este trabajo desarrolla una propuesta acerca de los criterios que debería acoger un tribunal internacional de derechos humanos para valorar qué grado de deferencia cabe otorgar al estado en la aplicación de un convenio regional de derechos humanos. Para ello se sugiere, en primer lugar, que el funcionamiento de una estructura internacional de protección de derechos debe regirse por criterios de legitimidad sistémica en vez de basarse en parámetros de legitimidad democrática o de compromiso. En segundo lugar, se defiende una concepción cooperativa del principio de subsidiariedad, la cual justifica la deferencia a las autoridades nacionales cuando éstas se hallen mejor situadas para adoptar una decisión sobre derechos humanos, pero, al mismo tiempo, condiciona la mejor situación del estado al cumplimiento de tres responsabilidades cooperativas: imparcialidad, cultura de la justificación y perspectiva convencional. Por último, se aplica esta concepción de la subsidiariedad para valorar críticamente dos sentencias en sede internacional, la primera, la sentencia del Tribunal Europeo de Derechos Humanos en el asunto S.A.S. c. Francia, la segunda, la sentencia de la Corte Interamericana de Derecho Humanos en el caso Gelman vs. Uruguay.
estructura del control de la discrecionalidad
Authors: Doménech Pascual Gabriel
Published: June 2024

El presente artículo pretende poner de manifiesto, en primer lugar, que el control de la discrecionalidad es un fenómeno que aparece en diversas esferas del ordenamiento jurídico, tanto en el Derecho público como en el Derecho privado, y que presenta en todas ellas aspectos y problemas comunes, que requieren y de hecho suelen recibir soluciones jurídicas análogas. El artículo trata también de hacer ver que, por esa razón, es posible y útil elaborar una teoría general (o un conjunto de teorías generales relativas a determinados aspectos) del control de la discrecionalidad, válida para cualquier sector del ordenamiento jurídico. En el artículo se esbozan a modo ilustrativo las líneas principales de una posible teoría general tal desde la perspectiva del análisis económico del Derecho.

Navigating reflux disease after achalasia treatments: Balancing risks and benefits
Authors: Griffiths Ewen A , Wong Enoch
Published: June 2024

The peroral endoscopic myotomy (POEM) procedure has revolutionized the management of achalasia in many centres around the world as it offers patients a minimally invasive endoscopic solution to their dysphagia caused by achalasia. Alongside its success in alleviating dysphagia, concerns regarding postoperative gastroesophageal reflux disease have emerged as a pertinent issue which are not fully resolved. In this study, Nabi et al have comprehensively reviewed the topic of the prediction, prevention and management of gastroesophageal reflux after POEM. POEM is a purely endoscopic procedure which is usually performed without any anti-reflux procedure. Certain patients may be better served by a laparoscopic Heller’s myotomy and fundoplication and it is important that gastroenterologists and surgeons provide comprehensive risks and benefits of each achalasia treatment option so that patients can decide what treatment is best for them. This article by Nabi et al provides a comprehensive review of the current status of this issue to allow these discussions to occur.

Authors: Gideon Antwi  , Dr. Matthew Kweku Essilfie
Published: June 2024

The study aimed to assess the patterns of variations in total phenolic content, total flavonoid content, and antioxidant activity in populations of A. viridis in two different ecological zones of Ghana. Matured plant leaves of Amaranthus viridis were collected at two different locations namely Aburi Botanical Gardens and Legon Botani-cal Gardens and were subjected to ethanolic extraction. The extracts were analyzed for antioxidant activity using 1,1-diphenyl 1,1-2 picrylhydrazyl radical scavenging, total phenolic content was analyzed usingFolin-Ciocalteu reagent, and total flavonoid content was also analyzed using the Aluminium chloride colorimetric technique. The correlation of total phenolic content and total flavonoid content, total phenoliccontent and antioxidant activity, and, total flavonoid content and antioxidant activity all yielded a directly proportional association. Thus, as total phenolic content increased total flavonoid content also increased andthis applies to all the scenarios above. There was a substantial difference in the phenolic content as Aburi Botanical Gardens had a higher phenolic content than Legon Botanical Gardens. The semi-deciduous forest ofthe Aburi Botanical Garden and the coastal savannah of the Legon Botanical Garden, two contrasting ecological contexts, have diverse effects on the phytochemical composition of Amaranthus viridis, as this study has clarified.

Introduction: Teaching work, which is characterized by being exhausting, with a significant workload, with synchronous and/or asynchronous remote classes. Objective: To describe associations between the working conditions of school teachers at home and their food consumption during the suspension of face-to-face classes. Materials and methods: Cross-sectional study using a self-administered online questionnaire with 15,372 working teachers from Minas Gerais, Brazil. The dependent variables analyzed were the consumption of healthy and unhealthy foods. Independent variables included sociodemographic factors, remote work conditions, understanding of online technologies, computer access, and quality of Internet connection. The Poisson model with robust variance was used to determine the association between working conditions and food consumption. Results: In the analysis of the adjusted multivariate model, there was a significant association between eating habits and the following variables: gender, age, working hours (per week), feelings regarding teachers’ work during the pandemic, working hours during the pandemic and quality work internet connection. Our data shows that teachers’ remote working conditions are associated with worse food consumption. They also showed that working hours equal to or greater than 40 hours per week, feelings of dissatisfaction with working conditions during the pandemic, increased working hours during the pandemic and poor quality of internet connection were variables correlated with the consumption of unhealthy foods. Conclusions: Remote working conditions during the pandemic influenced primary school teachers’ food choices. More studies are needed to delve deeper into issues related to teachers’ working conditions and the implications for food choices.
Die Wirkungen bodennahen Ozons auf die Vegetation in Deutschland – eine Risikoabschätzung/The Effects of Near-Ground Ozone on Vegetation in Germany – a Risk Assessment
Authors: Richter Simone , Wallek Stefan
Published: June 2024

Mensch und Umwelt sind in Deutschland und Europa nach wie vor häufig hohen Konzentrationen bodennahen Ozons ausgesetzt. Zur Einschätzung der Belastungsrisiken für die Vegetation stehen verschiedene Methoden zur Verfügung. Die flussbasierte Risikoabschätzung auf der Grundlage der phytotoxischen Ozondosis (Phytotoxic Ozone Dose, POD) bezieht dabei nicht nur die Umgebungskonzentration von bodennahem Ozon in die Berechnung ein, sondern auch die physiologischen Reaktionen der Pflanzen, die von meteorologischen Faktoren beeinflusst werden. Diese Interaktionen werden durch den rein konzentrationsbasierten Ansatz AOT40 (Accumulated Exposure over a Threshold of 40 ppb) nicht berücksichtigt. Somit kann der AOT40-Ansatz unter Umständen zu ungenauen Ergebnissen oder sogar falschen Schlussfolgerungen führen. Für die im Jahr 2023 abgeschlossene Berichterstattung zur Überwachung der Auswirkungen von Luftverschmutzungen gemäß Artikel 9 und 10 der Richtlinie 2016/2284 über die Reduktion der nationalen Emissionen bestimmter Luftschadstoffe [3] wurde der POD-Ansatz erstmalig genutzt. In diesem Artikel werden Ausschnitte der Berechnungen, die hinter dieser Berichterstattung stehen, erläutert. Exemplarisch wird das Ozonrisiko für die Rezeptoren Weizen (Triticum aestivum) und Buche (Fagus sylvatica) für den Berichtszeitraum 2009 bis 2021 in der Bundesrepublik Deutschland quantifiziert. Die Auswertung zeigt, dass im gesamten Zeitraum und bundesweit sowohl die Werte für den Rezeptor Weizen als auch für den Rezeptor Buche über den jeweiligen kritischen Belastungsgrenzen (critical level, CL) liegen. Das Risiko negativer Auswirkungen von Ozon auf Weizen variiert dabei zeitlich und räumlich stärker als das auf Buchen. Die fortwährende Überschreitung der kritischen Belastungsgrenzen verdeutlicht die Notwendigkeit, Maßnahmen zur Emissionsminderung von Vorläuferstoffen von Ozon zu verstärken, um das Risiko für Vegetation und Ökosysteme zu senken.

Feuchte- und Schimmelschäden zählen mit zu den relevantesten Schadstoffproblemen in Innenräumen. Die Etablierung von standardisierten Methoden zur Untersuchung solcher Schäden wurde in den letzten Jahren intensiviert. Eine dieser Methoden ist die Bestimmung der Gesamtsporenanzahl in der Raumluft. Der Verband Deutscher Baubiologen (VDB) führte seit 2005 diverse Probenahmevergleiche durch und entschied sich, ab 2019 einen Gesamtsporen-Ringversuch für Labore zur Überprüfung der Analysequalität durchzuführen. Dabei werden gleichartige Proben von den teilnehmenden Laboren ausgewertet. Die jeweiligen Vergleichswerte ermitteln vorab drei Referenzlabore. Bisher wurden vier Ringversuche dieser Art durchgeführt. Die Autoren beschreiben die Anforderungen an die Herstellung und Aus- wertung der Vergleichsproben sowie an die Bewertung der Ergebnisse. Die Ringversuchsausrichter sehen es als sinnvoll und notwendig an, dass Labore, die diese Methode in ihrem Leistungsspektrum anbieten, regelmäßig an den Ringversuchen teilnehmen. Entsprechende Qualitätsmaßnahmen sind z. B. im Zuge einer Akkreditierung der Methode notwendig.

Association of Single Nucleotide Polymorphisms (SNPS) to Black Spot Resistance in Roses
Authors: Yemer Genet Kebede , Debener Thomas , Linde Marcus , Maiss Edgar
Published: June 2024

Rose black spot caused by Diplocarpon rosae is the most severe and global disease of garden roses. Breeding of disease resistant varieties is one of the most important goals of modern garden rose breeding. Single nucleotide polymorphisms (SNPs) are the most abundant type of polymorphism found in eukaryotic genomes. SNP markers can be used in a wide variety of applications, including association studies, genetic diversity analysis, and marker-assisted selection in plant breeding programs. The aim of this project was to analyze black spot resistance in a rose association panel through leaf inoculation assays with single isolate pathotypes as well as a field mixture of D. rosae isolates and to establish a relationship between resistance and the available SNP markers. In this study, 96 diverse cultivars of roses were evaluated phenotypically for resistance against black spot through artificial inoculations. 63000 SNPs that were developed in previous studies were used to genetically analyze the cultivars and find associations with resistance against black spot disease using mixed linear model in TASSEL 3.0. Differences in the phenotypic reaction to field mixture of isolates and the Ab13 single conidial isolate of this pathogen were observed between genotypes. One hundred and forty-nine SNPs were found to be significantly associated with resistance against field mixtures of black spot. For the Ab13 single isolate, only one significant SNP was found. These SNPs were mapped on the rose chromosomes, and found on chromosome one, three and four. These associated SNP and Rdr1 markers can be used for marker-assisted selection in breeding for black spot resistance in rose.

Cayenne pepper is a vegetable commodity, which can be categorized as a commercial commodity and has the potential to be developed. The problem that arises is that more and more agricultural land is getting damaged. One effort to overcome this problem is to use organic fertilizers such as PGPR. The purpose of this study was to obtain the optimum dose of PGPR (Plant Growth Promoting Rhizobacteria) on the growth and yield (quantity and quality) of cayenne pepper in a monoculture cropping system and under the shade of mature citrus trees. The research was conducted in a Citrus Orchard, Tegalgondo Village, Karangploso District, Malang Regency. The time of the research was carried out in December 2022 - March 2023. This study used a Randomized Block Design (RBD) with two factors, namely the concentration of PGPR (Plant Growth Promoting Rhizobacteria) and the planting system. The first factor is the treatment of the application of the planting system which consists of 2 levels, namely MN (Monoculture) TS (Under the Orange Shade). The second factor was the treatment of PGPR concentration consisting of 4 levels, namely, P0 (without PGPR), P10 (10 ml.-1 concentration), P20 (20 ml.-1 concentration), P30 (30 ml.-1 concentration) and Treatment randomized in each group. and cropping system treatment. The results showed that there was no real interaction between the cropping system and PGPR on the growth of cayenne pepper plants. This is because there is a different effect on each treatment.

The excessive use of chemical fertilizer leads to a critical contribution to the environment, such as the decline of soil fertility and shallot productivity in the future. Whereas biofertilizer is one of the alternative ways to diminish the usage of chemical fertilizer to support sustainable agriculture. However, the majority of shallot’s farmers have a lack of knowledge towards biofertilizer. This study aims to analyze the influence of attitude, subjective norms, and perception toward the intention of using biofertilizers. This research was conducted in September 2022 – November 2022 in Gondang and Rejoso District, Nganjuk Regency, East Java, Indonesia. The respondents are considered by census method, and it is distributed to 140 shallot farmers who consist of biofertilizer users. The data was analyzed by using Partial Least Square (PLS) in order to examine the influence of attitude, subjective norms, and perception towards the intention of using biofertilizer. Overall, it is illustrated that attitude, subjective norms and perception have a positive and significant influence towards the intention of using biofertilizer among shallot farmers.

Pemupukan berimbang selalu diupayakan oleh peneliti dan petani untuk meningkatkan hasil sawi. Penambahan dosis pupuk organik perlu disesuaikan dengan dosis pupuk anorganik yang sedang digunakan. Sehingga penelitian ini dilakukan untuk mengetahui pada dosis pupuk organik dan anorganik berapakah dua jenis pupuk berinteraksi mempengaruhi pertumbuhan dan hasil sawi. Penelitian dilaksanakan pada bulan Maret hingga April 2023. Lokasi penelitian di Kota Batu, Jawa Timur. Faktor I adalah dosis pupuk hayati biokomplek yang terdiri: B0 = tanpa biokomplek, B1 = 5 ton.ha-1, B2 = 10 ton.ha-1 dan B3 = 15 ton.ha-1. Faktor II adalah dosis pupuk NPK yang terdiri : N0 = tanpa NPK, N1 = 150 kg.ha-1, dan N2 = 300 kg.ha-1. Dua faktor tersebut disusun menggunakan RAK secara faktorial. Diulang sebanyak 3 kali. Semua data pengamatan dianalisis menggunakan uji F 5%. Apabila terdapat signifikansi nyata antar perlakuan dilakukan uji lanjut BNJ taraf 5%. Pupuk hayati biokomplek 15 ton.ha-1 berinteraksi dengan NPK 300 kg.ha-1 menunjukkan pertumbuhan, hasil dan kualitas tanaman sawi hijau tertinggi dibanding perlakuan lainnya. Sehingga penggunaan pupuk biokomplek dibawah 15 ton.ha-1 dan pupuk NPK dibawah 300 kg.ha-1 tetap efektif dalam meningkatkan pertumbuhan dan hasil sawi. Selain itu, penghematan biaya pengeluaran untuk dua jenis pupuk bisa dilakukan. Sehingga penggunaan pupuk biokomplek 5 ton.ha-1 dan 10 ton.ha-1 yang ditambahkan ke 150 kg.ha-1 sudah mampu meningkatkan pertumbuhan dan hasil sawi hijau.

Salah satu faktor yang dapat membatasi produksi tanaman ubi jalar, di antaranya adalah serangan hama dan penyakit. Ubi Jalar (Ipomoea batatas (L). Lam) cv. Cilembu dilaporkan endemik dengan penyakit baru yang disebut gebogeun atau busuk keras. Serangan penyakit pada tanaman Ubi Jalar (Ipomoea batatas (L). Lam) cv. Cilembu ini terlihat terutama menjelang tanaman siap panen. Umbi tanaman ubi jalar tersebut mengalami gejala melaninisme dengan bentuk garis garis dan lingkaran berbentuk coklat sehingga umbi gagal dipanen. Tujuan dari penelitian ini adalah untuk mengidentifikasi patogen penyebab gebogeun atau busuk keras yang menyerang tanaman Ubi Jalar (Ipomoea batatas (L). Lam) cv. Cilembu. Penelitian ini dilakukan di Laboratorium Terpadu UIN Sunan Gunung Djati Bandung.. Metode yang dilakukan secara eksperimen dengan uji pathogenesis umbi yang bergejala hingga muncul gejala yang sama pada umbi yang sehat untuk membuktikan kesamaan gejala dari tanaman yang terinfeksi dengan tanaman atau umbi yang sehat. Pengamatan dilakukan secara makroskopis pada plate dan secara mikroskopis dengan menggunakan mikroskop cahaya. Berdasarkan hasil identifikasi baik secara morfologi, mikroskopis dan makroskopis dari beberapa isolat Ubi Jalar (Ipomoea batatas (L). Lam) cv. Cilembu yang bergejala menunjukan bahwa jamur tersebut adalah Boeremia exigua. Jamur ini telah menjadi penyebab penyakit gebogeun atau busuk keras pada tanaman Ubi Jalar (Ipomoea batatas (L).

Xanthomonas oryzae pv.oryzae merupakan salah satu bakteri patogen yang menyerang tanaman padi. Pengendalian terhadap penyakit ini telah banyak dilakukan dan salah satu teknik pengendalian yang dikembangkan saat ini melalui teknologi induksi ketahanan tanaman yang mengekspresikan gen PR-1. Penelitian kami untuk mendeskripsikan ekspresi gen PR-1 pada varietas padi IR64 yang terinduksi resistensinya oleh asosiasi antara bakteri endofit dan asam salisilat. Gen PR-1 dianalisis secara molekuler dan ekspresinya menunjukkan tanaman padi yang terinduksi resistensinya secara tunggal maupun kombinasi oleh kedua agens ini mem­perlihatkan adanya ekspresi protein PR-1. Ekspresi protein ini dipicu oleh aktivitas kedua agens penginduksi yang bekerja secara simultan untuk membentuk protein yang mampu menekan perkembangan penyakit ini. PR-1 bekerja sesuai dengan mekanisme dari masing-masing agens penginduksi resistensi tanaman. Varietas IR64 yang diketahui rentan terhadap penyakit hawar daun bakteri terbukti dapat ditingkatkan ketahanannya menjadi moderat.  Pemanfaatan induksi ketahanan tanaman melalui aktivitas kedua agens pengimbas yang membentuk protein PR-1 perlu dilanjutkan dengan inovasi formulasi teknik pengendalian yang diberikan secara simultan sebagai alternatif strategi pengendalian hawar daun bakteri maupun penyakit lainnya ke depan dengan pendekatan ramah lingkungan dan berkelanjutan.

Phonological learning is asymmetrical between prefixes and suffixes
Authors: Grachek Darby , Kaiser Elsi
Published: June 2024

Phonological theories typically treat prefixes and suffixes as if phonological processes apply uniformly to both. However, previous studies have found clear asymmetries between the behavior of both affixes. We argue that this is due to phonological processes being easier to learn in suffix position rather than prefix position. To test this, an artificial language learning task was used to evaluate whether phonological learning is symmetrical between affixes. Results pattern in the direction of the hypothesis, namely, that phonological learning is asymmetrically facilitated in suffix position over prefix position, providing support to general cognitive mechanisms being responsible for strong cross-linguistic tendencies.

Original research results of GFRP drilling, using HSS steel drill bit, pro-cess energy indicators were presented in the article. The research stand was a 5-axis DMU50 machining center, equipped with a Kistler force gauge with a signal ampli-fier and a DAQ data acquisition system. The obtained measurement data were pro-cessed using the force gauge manufacturer's software, a spreadsheet and the Statis-tica statistical data analysis package. As a result of the analysis, on the basis of tech-nological parameters and measured and determined values of cutting force and torque, changes in the values of selected process status indicators were determined; total and specific energy (per unit of material volume removed) generated when making individual holes as a function of the number of holes made. Moreover, the empirical value of the specific cutting resistance kc was determined. As a result of the experimental work carried out and the analysis of available literature in the scope of the article, conclusions were formulated regarding the energy indicators of the process – total and specific energy generated during processing, as well as possible causes of thermal damage to the processed material were indicated.
