Ball Balancing PID System using Image Processing
Authors: S C Pradeepa
Published: August 2022

Abstract: Control theory and its applications are crucial when operating within the area of dynamic systems. Compensating for disturbances and external actions imposed on a given system being inherently unstable or semi-stable. This project consists in the realization of a Ball-Plate system with 2 degree of freedom which will control the position of the ball by tilting the plate. Two servomotors will allow the table to be oriented with a certain angle of inclination to counterbalance the movements of the ball. A Pi camera placed above the device will transmit live images of the plate to a Raspberry Pi which will be responsible for analyzing them to draw conclusions such as the position of the all, its speed and acceleration. A Python program will then be responsible for processing these data, feed it to designed PID controller and transmitting the result by USB to the Arduino which will control the rotation of both servos independently. All the data will be sent to the Python program running in another computer using MQTT protocol. And set point, error and PID v/s time graphs would be plotted. The experiment is done by dropping a ball on the plate and waiting for the system response to balance the ball in the center of the plate and to follow the set trajectories. The plate is made of wood to ensure smooth slipping of the ball without friction. Balancing experiments were done, following the set trajectories, and positioning the ball at the center of the plate. Through the use of multithreading, image processing at the rate of 90 FPS was achieved. And results were plotted. In conclusion it should be emphasized that in control systems acceptable real time performance can be achieved by decentralizing the processing unit into several PUs. It is notable to mention that with small additional piece of software and control checkpoints PU redundancy feature can be added to the plant, so in the event of physical damage and PU failure the other PU can be notified and take over the system.

Published: August 2022

Abstract: Traffic congestion, energy conservation and environmental issues are fuelling the interest in light electric vehicles. In particular, electric vehicles are compelling because of their low cost, ease of use, lightweight, and extremely small footprint. This project deals with design and fabrication of a low-cost portable electric bicycle kit which makes use of electric energy as the primary source and can be mounted on any non-geared bicycle. It has two modes of drive; one is manual i.e. by pedalling and the other one is electric by using electric power from a DC battery. The kit consists of 250W PMDC motor which is powered by a 24V Li-ion battery. One of the major disadvantages of traditional bicycle is that it increases rider’s fatigue during long distance travel. The electric bicycle provides a better riding experience as it runs on electric power thereby reducing the rider’s fatigue. This helps in travelling longer distances comfortably. The electric bicycle is also faster compared to a traditional bicycle. It is also an environment friendly means of transportation as it does not depend on fossil-fuels for energy. The expected range of the bicycle is around 30-35 km on a single charge and expected speed is 20 kmph.
¿Por qué los pequeños productores de jitomate de San Pablo Güilá trabajan de manera individual?
Authors: Mendoza Ramírez Luis , Espinosa Trujillo Marco Antonio , López Cruz Evelyn
Published: August 2022

El objetivo de este estudio fue identificar los motivos intrínsecos que guían el comportamiento de los pequeños productores en relación con su resistencia a ser parte de alguna organización. El jitomate (Solanum lycopersicum L.) es el segundo producto agropecuario de mayor exportación de México, con presencia en 291 de los 570 municipios del estado de Oaxaca. Particularmente, en San Pablo Güilá existen 42.8 ha de invernaderos con jitomate para exportación; de esta superficie; 52% pertenece a 27 productores organizados en una cooperativa mientras que 48% restante es propiedad de 153 productores que trabajan independientemente. La investigación se llevó a cabo desde un enfoque cualitativo, con alcance exploratorio y descriptivo. La técnica utilizada fue la encuesta, adaptando el Cuestionario a la Descripción de Valores de Schwartz y se aplicó a productores que trabajan individualmente. Se encontró que los valores Tradición, Conformidad y Poder, son altos; Logro, Estimulación, Autodirección y Benevolencia son bajos; y Seguridad, Hedonismo y Universalismo son muy bajos. Se concluye que los agricultores tienen una orientación individualista enfocada en el éxito personal logrado por habilidades propias; así como en el control y en el dominio sobre personas y recursos.
Mitigasi Areal Banjir Pada Perkebunan Kelapa Sawit di Lahan Gambut Berdasarkan Pemodelan HEC-RAS 2D

Published: August 2022

Pengembangan perkebunan kelapa sawit di areal rawa dengan tanah gambut semakin meluas dan merupakan tantangan terbesar dalam pengelolaannya. Drainase yang sangat terhambat menjadi salah satu faktor pembatas yang mempengaruhi kondisi hidrologi lahan. Kajian hidrologi ini dilakukan di salah satu perkebunan kelapa sawit Kabupaten Tapanuli Selatan Propinsi Sumatera Utara yang mengalami banjir secara periodik. Pemodelan hidrolika pada kajian ini dilakukan dalam dua skenario yaitu kondisi aktual dan redisain dengan parameter yang dibutuhkan antara lain topografi lahan, klimatologi, dan hidrologi sebagai input dalam simulasi. Pemodelan hidrolika ini untuk mensimulasikan kondisi aktual kanal dan penerapan mitigasi permasalahan banjir dengan pembuatan tanggul menggunakan HEC-RAS 2D. Hasil simulasi menunjukkan bahwa banjir terjadi sebagai akibat luapan air Aek Sibirong yang mempengaruhi kondisi kanal dalam kebun yang terkoneksi dengan sungai tersebut. Berdasarkan simulasi, penerapan tanggul setinggi 1.15 m - 3.45 m pada bagian hulu dan 1.10 m - 3 m pada bagian hilir mampu mengatasi luapan air sehingga dapat mencegah terjadinya banjir pada areal kebun.
Resistencia a antibióticos y actividad antimicrobiana de aislados bacterianos de suelo antártico
Authors: Calisto Nancy Cristina
Published: August 2022

En este estudio 50 aislados bacterianos obtenidos de muestras de suelo antártico prístino, de las islas Rey George y Greenwich (Islas Shetland del Sur), y 25 aislados bacterianos de la rizósfera de Deschampsia antarctica Desv, se emplearon para determinar su capacidad antimicrobiana y su respuesta a 21 antibióticos. La susceptibilidad a los antibióticos se evaluó siguiendo el método de difusión en disco utilizando diferentes grupos de antibióticos: penicilinas, cefalosporinas, carbapenémicos, aminoglicósidos, quinolonas, tetraciclina, fenicoles, macrólidos, sulfonamidas y trimetoprim. La producción de compuestos antimicrobianos por los aislados bacterianos antárticos se determinó mediante el método de difusión en agar, utilizando como indicadores un panel de bacterias patógenas humanas Gram positivo y Gram negativo. Los aislados bacterianos estudiados mostraron resistencia a 14 (67%) de los 21 antibióticos probados. Tres aislados bacterianos (4%) fueron resistentes a al menos un antibiótico y 47 (63%) fueron multirresistentes. Además, 26 aislados bacterianos (35%) no muestran actividad antimicrobiana y fueron susceptibles a todos los antibióticos estudiados. Finalmente, 27 aislados bacterianos (36%) combinaron actividad antimicrobiana y resistencia múltiple a antibióticos y en promedio presentaron resistencia a 10 antibióticos. Los aislados bacterianos que combinan actividad antimicrobiana y resistencia múltiple a los antibióticos son especialmente interesantes ya que es probable que estas dos capacidades proporcionen una ventaja competitiva a las bacterias antárticas para permitirles sobrevivir en un entorno hostil. Adicionalmente, estos aislados bacterianos son nuevas fuentes potenciales de compuestos activos para el control de microorganismos patógenos.
De la “antigüedad araucana” a la “cultura artística”: discursos sobre la colección de platería mapuche del Museo de Arte Popular Americano (1893-1946)
Authors: Vargas Paillahueque Cristian , Quijada Aravena Felipe , Tobar Tapia Constanza , Parra Santana Carolina
Published: August 2022

El siguiente artículo problematiza los discursos en torno al arte indígena, específicamente del arte mapuche, a través de la trayectoria de la colección de platería mapuche de Pedro Doyharcabal, desde su formación, vinculada a los procesos de colonialismo en Wallmapu, hasta su incorporación al Museo de Arte Popular de la Universidad de Chile (1893-1946). A partir de una metodología basada en la revisión de fuentes primarias, se postula que su valoración desde lo etnográfico a lo artístico se debe al temprano aporte de investigadores, como Tomás Guevara y Claude Joseph, y a profundas transformaciones en la enseñanza artística y museos durante la primera mitad del siglo XX que permitieron problematizar la “cuestión mapuche”, desde la producción material de este pueblo y su lugar en el relato de la identidad nacional.
Diálogos entre la apropiación patrimonial, los grupos de interés y la producción científica: análisis comparativo de tres localidades costeras de la Patagonia Central (1989-2021)
Authors: Ciselli Graciela , Benegas Anahí , Curti Leticia
Published: August 2022

A partir del análisis descriptivo y la sistematización de experiencias comunitarias, científicas y gubernamentales que han tenido como objeto al patrimonio cultural en Comodoro Rivadavia, Puerto Madryn y Puerto Pirámides (Chubut), se comparan los procesos de patrimonialización emergentes en los últimos treinta años teniendo en cuenta la relación entre los modos de apropiación patrimonial, las normativas vigentes y los actores interesados en su preservación. Atravesadas por sus características fundacionales y un origen portuario común, las tres localidades han tenido un desarrollo diverso marcado por los sistemas productivos dominantes en ellas. Asimismo, las matrices culturales tanto de los pueblos originarios que habitan sus territorios como las corrientes migratorias (inicialmente galesa en el área VIRCH-Valdés) y una multiplicidad de orígenes étnicos (en el Golfo San Jorge) permiten explicar algunas de las iniciativas patrimoniales, el compromiso de las comunidades y las políticas gubernamentales.

Published: August 2022

El presente estudio busca caracterizar las percepciones de los docentes universitarios que imparten la asignatura de gramática en las carreras de Pedagogía en Lenguaje y Comunicación en Chile, con el fin de generar conocimiento respecto a cómo desarrollan sus clases, qué rol tiene la reflexión en su programación, así como también qué vínculos pueden establecer entre lo que se imparte en la universidad y el ejercicio docente futuro de sus estudiantes. Los resultados indican que la enseñanza de la gramática se considera como un aspecto central de la formación de estos profesores. Además, se precisa que los futuros docentes deben ser expertos, es decir, manejar el metalenguaje, lo que tendría incidencia en el conocimiento intuitivo que poseen los estudiantes en la escuela. Por último, los propósitos formativos indicados se centran casi exclusivamente en la figura del docente universitario y se pierde el foco en los estudiantes que están formando.

Tujuan artikel ini adalah untuk mengetahui beberapa komparasi atau perbandingan antara ilmu Badi’ Ibnu Mu’taz dan ilmu Badi’ kontemporer. Penelitian ini menggunakan metode kualitatif studi kepustakaan. Metode kualitataif yaitu suatu metode yang menghasilkan data deskriptif berupa kata-kata tertulis dari buku-buku yang berkaitan dengan masalah penelitian. Hasil dari pembahasan ini, penulis merangkum bahwa dalam ilmu Badi’ Ibnu Mu’taz membahas delapan belas kaidah pokok materi bukunya dan membaginya menjadi dua bab. Bab pertama dinamai dengan al-Badi’ yang berisi 5 kaidah. Sedangkan bab kedua dinamai dengan Mahasinu al-Kalam, yang berisi 13 kaidah didalamnya. Adapun ilmu Badi’ kontemporer terdapat dua bagian yaitu Muhassinat Ma’nawiyah, yang beirisi didalamnya 5 kaidah dan Muhassinat Lafdziyah yang berisi 3 kaidah. Ilmu badi’ ini lebih jelas dan rinci juga mudah dipahami dari pada ilmu Badi’ Ibnu Mu’taz dikarenakan pada masa dahulu belum banyak yang menggunakan teori ini dan tidak menjelaskan dari beberapa definisi istilah-istilah tersebut, dan hanya menyebutkan contoh- contohnya saja.

Published: August 2022

Abstract: This article aims to know the Ittijahat of Ibrahim Bin Al-Mahdy in his poem of Ritsa’. Ittijahat in this study is a description of the poet's tendency to divide Ritsa'. Ritsa is one of the various forms of Arabic poetry. To analyze the discussion problem, the author uses the descriptive analysis method, because this method is very appropriate to find out the picture and state of a thing by describing it in as much detail as possible based on the facts found in the data in question. The results obtained are: That Ritsa’ Ibrahim Bin Al-Mahdy varied in two directions namely, Nadb and Ta’bin. In the first direction, the poet tended to mourn his eldest son, where he showed a lot of sorrow, grief, and crying after his son went to the afterlife. Whereas in the second direction, the poet tended to eulogize his strength and highlight his heroism and masculinity, this arose because he was surprised by the sudden death of his son due to illness.

Keywords: Ritsa’, Ittijahat, Nadb, Ta’bin

The study aims to compare between an optimal portfolio of stocks formed with the Markowitz model and those formed with the Single Index model during the Covid-19 pandemic. This study's goal is to determine which model will give a higher expected return or lower portfolio risk. Samples used are the stocks member of index IDX BUMN20 which never leave the index, never had changes in shares amount in major and minor reviews, also didn’t do stock split along the period of January 2020 – January 2022. The study method used is a quantitative method with a cross-sectional approach. The results show that both higher expected returns and lower portfolio risk are given by the Single Index model. This demonstrates that the optimal portfolio formed with the Single Index model is better than those formed with the Markowitz model.

Published: August 2022

Este trabalho tem o objetivo de realizar uma descrição sobre como se dão as relações discursivas nos modos de produção e apreensão estética da música popular brasileira apresentadas no documentário “A linha fria do horizonte” de Luciano Coelho. Apresentaremos que a narrativa do documentário mostra a importância da conferência A Estética do Frio (RAMIL, 2004) para o engajamento entre artistas argentinos, brasileiros e uruguaios. Diante disso, podemos considerar que o documentário se mostra como uma continuidade da conferência, colocando Vitor Ramil e a Estética do Frio no “centro de uma outra história”, uma vez que os relatos apontam sempre para as canções populares e para as milongas do artista. Por fim, contemplamos em nosso trabalho a apresentação de elementos da Estética do Frio durante a narrativa do documentário. Para tanto, vamos nos deter às inserções musicais de Ramil e sua interação com as imagens propostas, que ora materializam conceitos da Estética do Frio ora apresentam imagens e o imaginário presentes em suas canções.

Este artigo tem como proposta discutir relações entre a mídia tradicional e as novas circulações, produzindo uma compreensão das condições de produção do jornalismo no país na atualidade, tomadas em sentido amplo como as determinações ideológicas em jogo na conjuntura histórica. A análise se apoia na teoria do discurso de Pêcheux (1988, 1990, 2016) e na distinção entre constituição, formulação e circulação dos discursos proposta por Orlandi (2001). Procuro levantar questões acerca desse momento de disputa em torno do “fato” jornalístico, considerando as formulações/ circulações que tencionam a notícia (informação) e a opõe às fake news (desinformação), no contexto do embate da mídia tradicional e das novas circulações com a materialidade do/no digital.
Efeitos de imbricação em discursos da/na mídia
Authors: Silva Silmara Dela
Published: August 2022

Este artigo se volta a reflexões teórico-analíticas acerca de práticas discursivo-midiáticas na conjuntura sócio-histórica brasileira, tomando como foco os discursos jornalístico e publicitário em seus processos de imbricação. Da perspectiva teórico-metodológica da análise de discurso de base materialista, busca-se refletir acerca do modo como acontecimentos jornalísticos em circulação na mídia passam a ser apropriados pelo discurso publicitário e, também, como o discurso publicitário produz efeitos nas práticas jornalísticas atuais. Como corpus de análise, foram mobilizadas práticas discursivo-midiáticas em torno da pandemia de COVID-19 no Brasil, materializadas em propagandas, informes publicitários e na chamada publicidade nativa. Os gestos de análise apontam para uma relação de proximidade entre as práticas discursivas jornalísticas e publicitárias na atualidade, o que não é sem consequências para a manutenção da mídia tradicional como instância de poder.
Violência e escola

Published: August 2022

Ocorrências como as de Columbine, Realengo e Suzano colocaram a violência escolar em evidência midiática. A mídia hegemônica brasileira, ao reportar eventos desta natureza, recorre ao jornalismo factual, e em nome da objetividade, desconsidera problematizações importantes. Este artigo objetivou analisar as narrativas midiáticas sobre o episódio ocorrido na Escola Estadual Raul Brasil, Suzano (SP), tendo como referência o portal de notícias G1. A fim de discutir os sentidos produzidos pelas narrativas desse portal, foi realizada uma análise hermenêutica com ênfase nos silenciamentos e marcas de espetacularização. Para contrastar formas de construção narrativa, o portal do EL País serviu de contraponto por sublinhar subjetividades e maior profundidade sobre o fato. O fio condutor de análise foi a abordagem noticiosa centrada nos executores dos disparos, que permitiram identificar que o G1 desprezou aspectos políticos, sociológicos e psicológicos sobre o evento, a escola e seus sujeitos.

Published: August 2022

Penyelenggaraan negara tidak terlepas dari administrasi. Periodesasi perkembangan administrasi ada dua yaitu secara umum dan paradigma, Â kedua periodesasi masih dipengaruhi administrasi dari negara maju. Secara umum, administrasi masih membandingkan dengan negara maju , sedangkan segi paradigma menurut Nicholas Henry membagi lima paradigma administrasi. Dimana masing-masing paradigma memiliki kajian berbeda. Munculnya diksi setelah â€œadministrasiâ€ menjadi pembahasan para ahli dari sasaran, pelaksana dan hasil pelaksanaan. Mulai dari istilah â€œnegaraâ€ sampai â€œpublikâ€ memiliki analisa Â serta paradigma berbeda. Ketika ada pernyataan Dwight Waldo bahwa administrasiÂ  berada di zaman kekacauan, konsentrasi administrasi mulai berubah, dimana sektor publik mulai dilibatkan. Istitlah negara mengacu peran penuh administrasi oleh, dari dan untuk negara, dimana sangat kecil porsi publik.Â  Sebaliknya kata â€publikâ€ menjelaskan administrasi dilaksanakan dengan konsentrasi rakyat berperan sebagai negara dan sasaran administrasi. Penyelenggaraan administrasiÂ  dipengaruhi jugaÂ  oleh paradigma Old Public Administration dimana terdapat New Public management, kemudian New public administration dan New Public service. Namun inti dariÂ  semua pelaksanaan administrasiÂ  menuntut adanya perubahanÂ  dari negara menjadi publik sentris. Perubahan paradigma menjadi goal oriented administrasi yaitu akuntabilitas, komprehensif dan transparasansi.
Sufisme dan Perubahan Sosial: Kaum Tarekat dan Dinamika Sosial Keagamaan
Authors: Khamim M.
Published: August 2022

Social change is a necessity. Every shift that occurs in society will trigger change. Religion is basically independent, which theoretically can be involved in terms of mutual influence with socio-economic realities. As an independent unit, for its adherents, religion has a high probability of determining patterns of human behavior and the form of social structures. In this way, religious teachings have the possibility to encourage or even restrain the process of social change. The existence of Sufism and tarekat in social life has an important role in social processes, one of which is social change. Through a qualitative descriptive approach with a research library that refers to related sources, this paper provides important point that tarekat has a dual function, namely as a religious-spiritual moral movement that directs its followers to always be close to God, and as a social and political social movement that helps guide its followers to have social sensitivity and care about social conditions, through the practice of teachings or doctrines that have been taught by tarekat organization.

Pandangan Muhammadiyah dan NU Terhadap Kebijakan Pemerintah Orde Baru Mengenai Penyeragaman Hari Raya Idul Fitri
Authors: Fatimah Anis
Published: August 2022

This paper tells about the New Order government policy in carrying out the uniformity of the Eid al-Fitr, thus demanding that several Islamic organization groups such as Muhammadiyah and NU carry out Eid al-Fitr simultaneously even though the method was always different in determining it. This research uses historical methodology through four main steps of historical method, namely: (1) heuristics, (2) source criticism, (3) interpretation, and (4) historiography. The results of this study indicate that government policies during the New Order era greatly influenced the politics of Islamic mass organizations in determining the time of Eid. This policy resulted in decisions that must be obeyed by all Indonesian people, especially Islamic organizations, so that the determination of the beginning of the qamariah month during the New Order period was almost always uniform.

El presente libro es una recopilación de varios años de trabajo, enfocados en el estudio cualitativo de modelos asociados a Microscopios de Fuerza Atómica (AFM). Las ecuaciones que describen los AFM, son del tipo Lazer-Solimini, es decir, ecuaciones diferenciales ordinarias no lineales con singularidades en la variable de estado. Los resultados obtenidos están centrados en establecer, o no, la existencia de soluciones T-periódicas al imponer en la EDO, un forzamiento externo oscilatorio. Las técnicas empleadas hacen parte del análisis no lineal tales como: el método de sub y super soluciones, la teoría del grado topológico, el método de Melnikov, entre otras. El libro se encuentra divido en tres capítulos: en el primer capítulo, se hace un bosquejo general acerca de los AFM y sus aplicaciones en diferentes áreas de la ciencia, junto con la deducción del modelo matemático. En el segundo capítulo, se encontrarán los resultados principales obtenidos en la investigación: se inicia con los diagramas de bifurcación para los modelos conservativos, posteriormente se establecen condiciones para la existencia, estabilidad y multiplicidad de soluciones periódicas no triviales en el modelo no conservativo sin disipación y finalmente, se caracterizan condiciones para la persistencia de las órbitas homoclinas en el modelo con disipación del tipo de película de compresión. En el tercer capítulo, se exponen los fundamentos teóricos que son utilizados en el desarrollo del documento, a la vez que, los códigos en Python que se usaron para contrastar los resultados teóricos.
A continental-scale survey of Wolbachia infections in blue butterflies reveals evidence of interspecific transfer and invasion dynamics

Published: August 2022

Infections by maternally inherited bacterial endosymbionts, especially
Wolbachia, are common in insects and other invertebrates but
infection dynamics across species ranges are largely under studied.
Specifically, we lack a broad understanding of the origin of
Wolbachia infections in novel hosts and the factors governing
their spread. We used Genotype-by-Sequencing (GBS) data from previous
population genomics studies for range-wide surveys of Wolbachia
presence and genetic diversity in over 2,700 North American butterflies
of the genus Lycaeides. As few as one sequence read identified by
assembly to a Wolbachia pan-reference genome provided high
accuracy in detecting infections as determined by confirmatory PCR
tests. Using a conservative threshold of five reads, we detected
Wolbachia in all but two of the 107 sampling localities spanning
the continent, and with most localities having high infection
frequencies (mean = 91\% infection rate). Three major
lineages of Wolbachia were identified as separate strains that
appear to represent three separate invasions of Lycaeides
butterflies. Overall, we found extensive evidence for acquisition of
Wolbachia through interspecific transfer between host lineages.
Strain wLycC was confined to a single butterfly taxon, hybrid
lineages derived from it, and closely adjacent populations in other
taxa. While the other two strains were detected throughout the rest of
the continent, strain wLycB almost always co-occurred with
wLycA. Our demographic modeling suggests wLycB is a recent
invasion. These results demonstrate the utility of using resequencing
data from hosts to quantify Wolbachia genetic variation and
provide evidence of multiple colonizations of novel hosts through
hybridization between butterfly lineages and complex dynamics between

Background/Aim. Popliteal artery aneurysm (PAA) is the most common peripheral artery aneurysm and the second most common aneurysm following abdominal aortic aneurysm (AAA). Still, its incidence is rare, and treatment is non-standardized. The collection of data in a multicenter registry could improve the diagnosis and treatment of PAA. SerbVasc is a newly established data collection collaboration among vascular centers in Serbia. The aim of this study was to present common surgical practices in the diagnosis and treatment of patients with PAA in hospitals in Serbia. Methods. Vascular centers in Serbia that accepted the invitation collected data retrospectively concerning patients operated on for PAA from 2012 to 2018. Data regarding symptoms, preoperative diagnostics, vascular and endovascular techniques, and postoperative results were collected. This data set was submitted to the VASCUNET international project of PAA for data analysis between the countries. The same data set was used for a detailed analysis of the contemporary treatment of PAA in six hospitals in Serbia: University Clinical Center of Serbia, ?Dedinje? Cardiovascular Institute, Military Medical Academy, University Clinical Center Novi Sad, University Clinical Center Nis, and General Hospital Uzice. Results. From 2012 to 2018, in six hospitals in Serbia, data for 342 procedures on treating PAA were collected for 329 (96.2%) men and only 13 (3.8%) women. The incidence of PAA repair was 6.8 operations per million inhabitants a year. The mean age of patients was 64.34 years (ranging from 29 to 87). A total of 223 (65.8%) elective procedures were performed. Am-putation and hospital survival were considered the main outcomes. Thrombosis was recorded in 110 (32.5%) pa-tients as a cause for surgery, and rupture was recorded in 5 patients. The mean diameter of the aneurysm was 35.3 mm, and a slightly larger diameter was recorded in ruptured aneurysms ? 43.8 mm on average. Both synthetic and vein grafts were used in elective and urgent procedures equally. Endovascular procedures were performed in 6 (1.8%) cases. Conclusion. This study confirms the importance of registry-based collection of data and their analysis. It showed that the national incidence of PAA in Serbia is low and that well-organized, even institution-based, screening algorithms should improve identifying such patients and increase the number of electively treated PAA. Educating vascular surgeons to use the posterior approach could improve vascular healthcare.

The purpose of this work is to identify a Robin coefficient from available measurements on the accessible part of the boundary. After recasting the inverse problem as an optimization problem, we study the issue of identifiability, stability, and identification. For the reconstruction process, two regularized algorithms are designed, and the forward problem is approximated using the discontinuous dual reciprocity method. The accuracy of the proposed approaches is tested in the case of noise–free and noisy data and the findings are very promising and encouraging.

This study intended to know the effectiveness of E. purpurea as an immunomodulator against AI and ND antibody titer in male broilers, and conducted in December 2018 until January 2019 at Lapang Terpadu Laboratory, Faculty of Agriculture, University of Lampung.  Antibody titer analysis was done in Virology Laboratory of Balai Veteriner Lampung.  The study was conducted on 60 samples of Lohmann male broiler with four treatments, P0 (drinking water without E. purpurea), P1 (drinking water with 3 mg/kg BW/day E. purpurea), P2 (drinking water with 6 mg/kg BW/day E. purpurea), and P3 (drinking water with 9 mg/kg BW/day E. purpurea). The results showed that E. purpurea (Radix) was effective to increase Avian Influenza antibody titers and was not effective to increase Newcastle Disease antibody titers in male broilers. E. purpurea (Radix) at a dose of 6 mg/kg BW/day can increase AI antibody titer in male broilers.

The bird nest adoption program in Jatimulyo is one of the activities to protect birds from extinction. This activity is carried out by keeping birds that are breeding in nests in community forest habitats. The development of this concept was expected to protect the birds and increase the economic value of the community-owned forest from the non-timber sector that supported environmental sustainability. However, the program is not yet implemented in the whole area of Jatimulyo Village. This study aimed to determine the strategy for developing the bird nest adoption program in Jatimulyo Village. Data was collected through in-depth interviews with expert respondents with extensive experience and knowledge of the studied problems. The data that has been collected was analyzed using SWOT analysis. The SWOT analysis results showed that an offensive strategy is needed to develop the bird nest adoption program, which can be carried out by utilizing strengths to seize opportunities. There are five alternative strategies, i.e. (1) increase the number of nest findings to be adopted to increase people’s incomes; (2) take advantage of the attention of the government and other institutions to strengthen farmer groups and support the management of adoption programs; (3) opening access to birdwatching special interest tours by involving the community as local guides; (4) encourage bird protection in the Jatimulyo area and jointly promote bird nest adoption program; and (5) expanding the adoption area in Jatimulyo Village.

The development of technology has rapidly affected the growth complexity of the 21st century's work environment which also influences educational environment. Thus, approaches in teaching and learning such as self-determined learning has been considered relevant to enhance the quality of learning. Researchers and educators have been pursuing to accomodate the praxis of self-determined learning. The purpose of the study was to uncover research trends and try to bridge the gap of future research of self-determined learning (SDL) in the English as a foreign language (EFL) context. Using meta-synthesis, 13 selected articles were examined drawn from a single database from the last five years between 2017 and 2021. The articles were systematically selected through several criteria using the query "Self-determined Learning+AND+EFL" in the Sopus database. They contributed to the growing interest related to research and practice of heutagogy or SDL. Results showed that research areas of SDL had been widely investigated in different levels of students; primary (23%), secondary (23%), and university (54%). In addition, a few research studies were conducted to examine students' language skills and language components (listening and vocabulary) (15%). It implicated that many EFL research area could be investigated from different levels and focus in the future.
