Broadband All-Metal Vivaldi Array Antenna with Pyramidal-Shaped Wings for LEO Satellite Applications
Authors: Jang Doyoung , Lim Tae Heung , Park Seulgi , Choo Hosung
Published: October 2023

In this paper, we propose an all-metal Vivaldi antenna with pyramidal-shaped conductive wings for use in satellite signal intelligence applications. The inner metal Vivaldi antenna consists of radiating flares and a transition part between the feeder and the flares. The curvature of the inner flares is optimized, while the outer edges of the radiating flares are connected to the pyramidal-shaped wings to obtain a higher antenna gain over the entire operating frequency band. To verify the antenna’s feasibility, performance aspects such as the reflection coefficient, the radiation patterns, and the boresight gain are measured in a full anechoic chamber. The fractional bandwidth of the proposed antenna is 54%, while the boresight gain is greater than 7.3 dBi in the frequency range from 8 GHz to 12 GHz. To examine array performance aspects such as the total gain and beam steering, the proposed Vivaldi antenna is extended to a 4 × 1 linear array configuration. When the main beam is steered from 0° to 15°, the maximum gain is varied from 14.5 dBi to 13.7 dBi, while the side lobe level is decreased from 11.2 dB to 6.3 dB.

In this paper, we introduce and develop a new definitions for Katugampola derivative and Katugampola integral. In particular, we defined a (left) fractional derivative starting from a of a function f of order α∈(m-1, m] and a (right) fractional derivative terminating at b, where m ∈ N. Then, we give some proprieties in relation to these operators such as linearity, product rule, quotient rule, power rule, chain rule, and vanishing derivatives for constant functions.
Evaluation of carotid artery Doppler measurements in late-onset fetal growth restriction: a cross-sectional study
Authors: Kucukbas Gokce Naz , Doğan Yasemin
Published: October 2023

Background/Aim: It has been reported that both the internal carotid artery (ICA) and the common carotid artery (CCA) are associated with hypoxia, also observed in late-onset fetal growth restriction (FGR). However, it has not yet been investigated whether these Doppler measurements differ in cases of late-onset FGR. This study evaluated the ICA and the CCA Doppler parameters in late-onset FGR fetuses and compared these measurements with those of healthy fetuses.
Methods: This cross-sectional observational study comprised 75 singleton pregnancies diagnosed with late-onset FGR between the 32nd and 37th weeks of gestation, alongside 75 healthy fetuses paired 1:1 based on obstetric history and gestational age between June 2022 and May 2023. The Delphi consensus of 2016 was used for the definition of late-onset FGR. The exclusion criteria were congenital anomalies, presence of any additional disease, maternal body mass index over 35 kg/m2, abdominal scars hindering ultrasound visualization, use of medications such as antenatal steroids, sympathomimetics, and indomethacin that affect vascular function, drug use, smoking during pregnancy, concurrent preeclampsia, and multiple pregnancies. Upon the patients' admission to the hospital, their demographic characteristics were documented, and ultrasonographic examinations and Doppler measurements were subsequently performed. The Doppler velocimetry of the umbilical artery (UA) encompassed measurements of the systolic to diastolic ratio (S/D), pulsatility index (PI), and peak systolic velocity (PSV). The carotid artery Doppler velocimetry of the middle cerebral artery (MCA), ICA, and CCA encompassed measurements of the PI, resistance index (RI), and PSV. We assessed the diagnostic performance of Doppler measurements for late-onset FGR through receiver operating characteristic (ROC) analysis.
Results: In the late-onset FGR group, the mean UA-SD was higher (2.7 [0.6] vs. 2.5 [0.5], P=0.006), and the mean UA-PI (0.8 [0.2] vs. 0.9 [0.2], P=0.011) and mean PSV (35.6 [8.2] vs. 41.1 [7.1], P<0.001) were lower compared to the control group. In the late-onset FGR group, carotid Doppler measurements were more pronounced than UA Doppler measurements. Moreover, ICA Doppler measurements exhibited superior diagnostic performance in predicting late-onset FGR compared to other Doppler measurements (Area under the curve [AUC]=0.777, P<0.001 for ICA-PI; AUC=0.751, P<0.001 for ICA-RI; AUC=0.749, P<0.001 for ICA-PSV).
Conclusion: In fetuses with late-onset FGR, UA Doppler measurements showed minimal differences compared to healthy fetuses, but differences in carotid Doppler measurements, especially in the ICA, were more pronounced. Therefore, in the management of fetuses suspected of having late-onset FGR, a more detailed Doppler examination might be required.

El cultivo de café en la región de La Montaña de Guerrero es atendido por familias indígenas, las cuales tienen un deficiente manejo de la huerta en lo que influye la escasa solvencia económica y falta de apoyo institucional, de aquí la importancia de conocer qué factores limitan la producción. El objetivo de la investigación fue sistematizar el proceso de producción de café de Paraje Montero para detectar los puntos críticos que permitan mejorar la producción. En 2019, se entrevistó a 83 productores de café para recabar información sobre el proceso de producción. La edad promedio de los productores fue de 55 años con siete años de escolaridad; el 94% de ellos se dedicaban a la agricultura. En promedio tenían 2.6 ha con café como monocultivo y policultivo con frutales, plantas de ornato y medicinales. El 98.8% cultivaba la variedad Typica (criolla) con plantaciones de 34 años promedio y 493 plantas ha-1. Las actividades en el cafetal se realizan principalmente con mano de obra familiar. Los problemas detectados fueron un escaso manejo de la huerta (deficiente poda, fertilización y control de plagas y enfermedades) que ocasiona rendimientos bajos; se tienen precios bajos, falta de apoyo institucional y escasa solvencia económica. Es importante atender estos factores mediante la organización, gestionando la participación de los productores para asistencia técnica y capacitación como alternativa para mejorar la producción del cultivo de café.

Bengal gram was grown under three differont plent spacings (30 x 10 cm, 45: 10 cm and 30x20 cm) during 1973 Kharif season at Tamil Nadu Agricultural University experimental farm. At the time of harvest, 50 plants in the centre of each plot were selected at random and data on grain weight por plant and grain number per plant were collected. Considering replication as primary sampling units and plants within plots secondary sampling units. variance components viz. variance among plants within plots were estimated for the two characters seperately at 'each spacing using analysis to variance technique. It was observed that more than 86 per cent variability was attributed among plants within plots and rest among plots. Plants spaced with 45 x 10 cm and 30: 20 cm exhibited more variation then plants with 30x 10 cm suggesting selection of more sample plants in wider spaced treatments for estimation purposo. The relationship between mean and variance indicated that the two characters can be analysed with anginal values and their means compared in comperative experiments. To estimate grain weight per plant and grain number per plant. with a precision of 5 par cent standard error, a minimum of 116 and 65 plants respectively were considered necessary.

An investigation was carried out with ten varieties of wheat to find out the information on genetic variability present among them which could be useful as sound basis for selection of superior ones. The analysis showed higher genetic variability in number of productive tillers per one metre length, height of plant and duration. Heritability estimates revealed that almost all characters except number of grains per panicle have high heritability value. Genetic coefficient of variation is highest for the grain weight par plot followed by height of plant. High heritability value combined with high genetic advance has been exhibited by the height of plant, duration in days, length of panicle and grain weight per plot.

Sixteen cultivars of blackgram were studied for assessing the association between yield and its component characters. A significant positive association existed between seed yield and all the yield components studied. The co-heritability estimates between the various pairs of characters indicated that the strength of association of all other characters with height of plant is high as against the association of them with branch number. The path analysis showed that two characters namely the height of plant and cluster number have a direct effect as well as indirect effect via. other characters on seed yield, while branch number, pod number, pod length and seed number per pod have either very low positive or high negative, direct or indirect effects on seed yield. As such the height of plant and cluster number are important yield components to be considered.

An unidentified species of Pseudomonas capable of utilising Carboxin and Oxy- carboxin as sole source of carbon and nitrogen was isolated from red sandy loam soil perfused with solutions of these fungicides. The bacterium hydrolyzed Oxycarboxin to aniline and oxidised Carboxin to the corresponding sulphoxide and then to the sul- phone. The sulphone derivative was further hydrolyzed liberating aniline. Further, deg- radation of aniline by the organism resulted in the accumulation of ammonium which was partly oxidized to nitrite. Nitrite accumulated in the media without further oxidation to nitrate.

Azotobacter treatment to seed seedling and soil helped good initial plant growth and better tillering of paddy. When applied in combination with 75 per cent of the re- commended dose of fertilizer nitrogen, the Azotobater could compensate 25 per cent of fertilizer N and bring out the same yield of paddy crop as that of cent per cent fertilizer N without Azotobacter treatment, thereby reducing the cost of cultivation. Azotobacter treatment with cent per cent of the recommended dose of fertilizer N resulted in the increase of grain yield slightly. Azotobacter treatment to paddy during January-May season brought out the beneficial effects convincingly than during the August-December season.

Authors: Núñez Bustos Ezequiel
Published: October 2023

Misiones es la provincia argentina con mayor biodiversidad del país. En lo que respecta a Lepidoptera y en especial a mariposas diurnas existen más del doble de especies que en las restantes provincias. Sin embargo, aún hay especies de países limítrofes no halladas en territorio argentino. En este trabajo se dan a conocer a través de material colectado y fotografías, quince registros inéditos de Papilionoidea para Argentina (8 Lycaenidae, 1 Riodinidae y 6 Hesperiidae), de los cuales cuatro géneros eran inéditos para el país (Cupathecla, Perophthalma, Nicephellus y Zonia), todos de Misiones. Hay también tres nuevos registros provinciales (Strymon lucena, Heliopetes orbigera y Zopyrion evenor). Se confirma la presencia de Yphthimoides yphthima para el sur de la provincia y de Adelpha plesaure phliassa para el Parque Nacional Iguazú. Después de 91 años sin registros, se halló a Protelbella ruficauda en el este de la provincia. El presente trabajo confirma que en Misiones aún hay muchas especies más por citarse para el país.
A Companhia de Jesus e seu papel na formação de bibliotecas no Brasil colonial
Authors: Curvo Luiz Felipe Sousa , Santos Maria Luíza Lucas dos
Published: October 2023

As primeiras escolas e bibliotecas do Brasil surgiram a partir da segunda metade do século XVI e são obras da ação doutrinária das ordens religiosas, em especial da Companhia de Jesus, inserindo-se no contexto do projeto colonial da Coroa Portuguesa. Na trajetória de suas instituições escolares, os jesuítas atuaram na catequização de indígenas e na formação dos colonos pertencentes à elite. Em seus colégios, que tiveram seu apogeu no século XVIII, a escrita e a leitura eram centrais dentro da racionalização pedagógica, contribuindo para o desenvolvimento de importantes coleções de livros com temas variados até a expulsão da Ordem em 1759. Este trabalho cuja metodologia é a pesquisa bibliográfica de cunho exploratório, possui como objetivo principal analisar as origens e o desenvolvimento das bibliotecas jesuítas no Brasil a partir da práxis educativa e evangelizadora que lhes dava razão de constituição até o seu desmonte promovido pelas reformas pombalinas.

Alternative ideas about concepts of physics, a timelessly valuable tool for physics education
Authors: Kotsis Konstantinos T.
Published: October 2023

Alternative ideas, defined as faulty or incomplete understandings of scientific concepts, are prevalent among students across all age groups and educational levels. In physics, misconceptions often arise from everyday experiences, intuitive reasoning, and oversimplified analogies. The persistence of misconceptions in students’ understanding of physics concepts can hinder learning and compromise scientific literacy. Consequently, research on alternative ideas has emerged as a critical aspect of science education, informing teaching strategies and curriculum development. At the beginning of this research, a brief historical report is presented on how research began in the field of the didactic of physics. Then a report is presented with research that led to the identification of alternative ideas at various levels of education. Finally, modern studies on the alternative ideas on the concepts of physics and their conclusions are presented and highlight the timeless necessity of the scientific research of alternative ideas and students’ perceptions of physics concepts, proving how valuable it is for physics education in the search for this topic.

Através das articulações teórico-metodológicas dos Estudos Culturais e das epistemologias decoloniais, neste artigo pretendemos perceber de que modo as marcas nativas da cultura hip-hop podem empreender seus esforços pela decolonialidade, pelo resgate da ancestralidade, história e identidade dos povos subalternizados que julgam representar. Uma breve exploração de alguns objetos por onde se materializam as formas de representação do Laboratório Fantasma demonstra em que medida a marca empenhou-se pelo reconhecimento de um sentido estético e político em sua trajetória e seu papel na cultura hip-hop brasileira.
Specificities of welds formation with aluminum alloy AK 9 obtained by selective laser melting
Authors: Ovchinnikov Viktor , Reztsov Ruslan
Published: October 2023

The problem of obtaining high-quality plate welds made of AL9 alloy and powder by selective laser melting is viewed. Welded butt joints of plates of AK9CH alloy with a thickness of 3.0 mm were made by melting welding (automatic argon arc and electron beam welding) and friction stir welding. After welding the base metal of the AK9 alloy plates and their welded joints were subjected to X-ray transmission, computed tomography, metallographic analysis and mechanical tests for static tension and static three-point bending. X-ray inspection of welded joints made by automatic argon arc and electron beam welding revealed multiple porosity inside welds. The nuclei of pores in the weld metal are spherical micropores, formed in the parent metal during selective laser melting. The diameter of these micropores is 150...200 microns. In the welding bath during fusion welding, micropores develop up to 420...1070 microns in diameter in case of argon arc welding and 215...420 microns in case of electron beam welding. Metallographic analysis of cross-sections of welded joints performed by fusion welding revealed a characteristic pore distribution in the weld metal. So in case of argon arc welding, the largest pores were located near the front surface of the weld. In the fusion zone at the border of the weld and the base metal, pores with a diameter of 80.220 microns were located in the form of chains along the entire thickness of the plates being welded. When testing welded joints for static tension, the destruction of joints occurred precisely in this zone. The strength coefficient of the AK9 alloy joints obtained by fusion welding is as follows: for automatic argon arc welding 0.46, for electron beam welding - 0.66. It is established that the problem of porosity of welded joints is eliminated when using solid -phase welding for jointing (friction stir welding). The strength coefficient of the jointing of the AK9CH alloy plates made by friction stir welding is at the level of 0.81.0.86 of the time resistance of the base metal. The destruction of welded joints occurs along the mixing zone. In the weld zone during friction stir welding, as a result of dynamic recrystallization, a fine-grained equiaxed structure with an average grain size of 4.5...6.2 microns was formed with virtually no pores. The parent metal is represented by a cellular structure in which there are pores up to 168 microns in size.
