Authors: Rajesh S R  , Kanniga E  , Sundararajan M
Published: January 2021

Diabetic retinopathy (DR) be the significant difficulty of diabetes, and micro aneurysm (MA) is an earliest diabetic retinopathy lesion, making early detection of MA a key factor in diabetic retinopathy. DR is a direct or indirect effect on human vision caused by chronic diabetes. During its early stages DR is asymptomatic, and the late diagnosis leads to undeviating vision loss. The computer-assisted diagnosis helps with prompt and effective care, with the aid of medical photos. MA mark the beginning of DR making it a vital screening stage for this disorder. Diabetic retinopathy is a persistent infection of eye that can be the reason of blindness unless it is diagnosed and treated in due course. Early discovery with analysis of diabetic retinopathy is vital to vision preservation of patient. Precise recognition of MA be the crucial method towards early diagnosis of DR, since they occur as the first symptom of the disease. The segmentation of MA is performed using the Fuzzy C algorithm, and the extraction of features is performed with Gray Level Co-occurrence Matrix ( GLCM) as the set of characteristic for KNN. This technique aims to improve classification accuracy within an ensemble. A procedure is suggested here that recognizes the first DR sign called MA using images from the retinal fundus. Effective diagnosis of DR is very critical in the defense of patients' right to see. The procedure proposed is tested using publicly available databases of retinal images and greater accuracy is achieved.

A study on the minimum transmission dose for image formation in X-ray imaging of forearm, femur and ankle joint
Authors: Sinyoung Yu
Published: January 2021

Excellent performance of the digital detector can generate medical images at a lower dose. However, if a certain level of dose exposure of the sensor detector can generate an image to recognize it. In this study, the exposure conditions of the forearm, femur, and ankle joint tests currently used in clinical trials were tested with lower doses. The resolution pattern was analyzed using the Image J program, and the results were obtained by analyzing the Interactive 3D Surface Plot. In addition, by measuring the surface dose and absorbed dose, the digital detector finds the minimum conditions to make an image and also checks the effect of dose reduction. The image of the obtained resolution pattern was analyzed by Plot profile using Image J program. It was confirmed that the gray value width decreased at the same pixel distance as the exposure conditions decreased. Even if the exposure conditions were lowered from step 1 to step 4, which is the standard condition of the forearm test, the resolution showed no difference at 1.4 Lp/mm. In the Interactive 3D Surface Plot, as the range of the grayscale lowered the exposure condition, the shape of the surface contours gradually became blurred, and the contrast of black and white shades decreased. The resolution from step 1 to step 3, which is the standard condition of the femur bone test, was 1.2 Lp/mm, indicating no difference. Even if the exposure conditions were lowered from step 1 to step 4, which is the standard condition for ankle examination, the resolution showed no difference at 1.4 Lp/mm. It is thought that it is necessary to accumulate a lot of data by further subdividing the stage of exposure conditions according to the thickness in more areas.

Published: January 2021

Understanding source and sink pattern of coral larvae is among the key elements for effective ecosystem management and future habitat restoration. This study examined dispersal pattern of coral larvae among three known inshore reefs (Pulau Ular, Balok Reef and Raja Muda reef) in Kuantan coastal waters by simulating virtual larvae trajectories during spawning event in 2018. Dispersal pathways were modelled and constructed by incorporating biological traits (timing of spawning and pelagic larvae duration) using Langragian particle tracking module integrated with 2-dimensional, hydrodynamic, flexible network model (MIKE 21 FM). Results indicated that Acroporid larvae moved in southward direction throughout dispersal period. Source and sink dynamic suggested that Pulau Ular has high larvae retention (70%) in which most of larvae originated from natal reef. Balok reef was dominant source of larvae for Raja Muda reef. Results also indicated that patches reefs near Raja Muda was ideal sink site for coral larvae and should be prioritized for future ecosystem management action.

Authors: Noor Rana Shahzad , Hussain Fiaz , Saad Abu , Umair Muhammad
Published: January 2021

Maize (Zea mays) is one of Pakistan’s most important cereal crops and is widely used both for human consumption and for livestock feed. Seed germination, its morphological growth and yield depends on irrigation sequence. Rainfall is the only source of irrigation in Potohar region, Rawalpindi which mainly restrained sustainable agricultural practices. Therefore, a study was planned to investigate the effect of different irrigation frequencies (1-day, 3-days and 5-days interval) on germination and early growth of maize at Koont research station, PMAS-Arid Agriculture University, Rawalpindi during 2019 and 2020 crop seasons. The results elucidated that the continuous application of enough moisture via irrigation in 3-day interval enhance relatively higher (50%) percentage of germination followed by one day interval (43.75%). The enough moisture at five-day interval enhanced germination performance (68.75%). No significance effect was found on number of maize seedlings emergence while a considerable variation was observed on their emergence date, that the early emergence of maize seeds was enhanced in 1-day interval. As irrigation frequency decreased from 1 to 5 days interval, seedling emergence was delayed significantly (p<0.05). This indicated that a continuous application of enough water to the soil and maintaining soil moisture enhance the emergence of maize seeds to be takes placed earlier.

Motorcycles are the most popular among Indonesian people, especially the lower middle class to facilitate mobilization in daily activities. As the rapid growth of motorcycle, the number of criminal motorcycles theft is also high. criminal motorcycles data for 2018 amounted to 27,731 cases and for 2017 there were 35,226 cases. Motorcycles are often the object of theft because it is easier in terms of mobilization in terms of the theft process to the sale to collectors compared cars and above. In addition, the security side provided by motorcycles manufacturers is still relatively low, only a few manufacturers have listed an alarm feature in their production. The modus operandi that the perpetrators often use is to destroy the key house by using the T key, but also by seizing directly, pretending to borrow to spread nails on certain streets. This study aims to develop a tool (Smart motor) that can be used as an anti-theft security with the media validation of the driver's license and vehicle registration so that the motor can not be turned on if it does not bring the driver’s licence and vehicle registration registered on the device. With the device built, the owner is required to bring the vehicle registration and driver’s licence so that the motor can be turned on. This is also useful in order to comply with traffic rules set by the police, namely by carrying a complete driving while traveling

Published: January 2021

With students spending up to 20% of their in-class time texting, emailing, and checking social media, it is no wonder the problem about smartphones in the classroom arises. This article presents results of a piece of research focused on the analysis and reflection of the smartphone applications used with higher education students in order to provide, as well as to improve, their results in departmental exams while they are studying English at a professional level.

The study took place over one semester of a curricular English course where smartphone applications were carefully selected and integrated into the current didactic units of the standardized institutional English program, with the purpose of finding, in the school of tourism and gastronomy, not only a solution, but a different approach to turning the problem into part of an updated methodology for the foreign language classroom. 

The results of this research are expected to have a significant impact on the improvement of the methodology used by teachers at all the schools on our institutional English program with the effect that, once the teachers begin to implement the systematic use of  smart phone applications in the delivery of their lessons, learners will hopefully perceive the English course as more relevant and  meaningful and be motivated to achieve the expected results.

This paper gives, for the first time, details of the vascular plants plus the soluble salts and other major components of their natural substrate in Salada Farrachuela, a hypersaline wetland located in the municipality of Tamarite, NE Spain. The wetland is situated on the outcropping evaporite-cored Barbastro Anticline, an area declared by the environmental authorities to be of community interest and part of the Natura 2000 network. This uncultivated and occasionally flooded wetland harbors plants able to withstand the conditions of their substrate whose upper layer (0–25 cm) has an average of 41% gypsum (CaSO4•2H2O), and 7.2 dS m−1 at 25 ºC electrical conductivity in 1:5 soil-to-water weight ratio (EC1:5) extracts. The EC1:5 value in the soil samples up to a depth of 2 m ranges from 6.23 to 7.95 dS m−1. At this depth, the average EC in the saturation extracts (ECe) is 37.0 dS m−1, with sulfate being the most abundant ion (503 meq L−1), followed by magnesium (492 meq L−1), sodium (113 meq L−1), and chloride (41 meq L−1). Salinity, hydric conditions, and halophilous vegetation contrast distinctly with the surrounding nonsaline gypseous land and its gypsophilous vegetation. This article provides a baseline for future investigations of the ecology of this wetland in relation to salinity, and a reference for the monitoring needed to guarantee its conservation.

Este artículo da por primera vez noticia de las plantas vasculares y de las sales solubles y otros componentes mayoritarios del suelo de la Salada Farrachuela, un humedal hipersalino situado en el municipio de Tamarite de Litera, provincia de Huesca, en el NE de España. El humedal se localiza en el afloramiento del núcleo evaporítico del anticlinal de Barbastro, un área declarada de interés comunitario incluida en la Red Natura 2000. Este humedal, inculto e inundado ocasionalmente, alberga plantas adaptadas a un suelo cuya capa superior (0-25 cm) tiene por término medio un 41% de yeso (CaSO4•2H2O), 7.2 dS m−1 a 25 ºC de conductividad eléctrica en el extracto acuoso 1:5 en peso de suelo:agua (EC1:5). Para ese espesor de suelo, la conductividad eléctrica en extracto de saturación (ECe) a 25 ºC es 37.0 dS m−1, siendo el sulfato el ión más abundante (503 meq L−1) seguido del magnesio (492 meq L−1), sodio (113 meq L−1), y cloruro (41 meq L−1). La salinidad, las condiciones de humedad y la vegetación halófila contrastan fuertemente con las tierras circundantes, yesosas y no salinas. Este artículo puede ser un punto de partida para futuras investigaciones de la ecología del humedal en relación con la salinidad, y una referencia en el futuro seguimiento necesario para garantizar su conservación.
Polémicas sobre una memoria ornitológica premiada y publicada por la Real Academia de Ciencias de Madrid (1882-1887)
Authors: Garrido Sánchez Manuel
Published: January 2021

Resumen
La Real Academia de Ciencias Exactas, Físicas y Naturales de Madrid premió la obra Aves de España. (Un dato más), presentada a concurso público correspondiente al año 1882. Escrita por José Arévalo Baca, el ornitólogo español del siglo XIX más reconocido a escala europea, catedrático desde 1877 en la Universidad de Valencia. En el proceso de revisión, la Sección de Ciencias Naturales de la Academia, evaluadora de la Memoria, indicó en su informe que el autor se había aprovechado de los trabajos inéditos de dos profesores ya fallecidos de Málaga y Valencia, sin citarlos: Higinio Aragoncillo del Villar y Rafael Cisternas Fontseré. Conclusiones que fueron refutadas por Arévalo con argumentaciones y datos inéditos que aportamos en este trabajo, pero que no impedirían que tras la publicación de su memoria ornitológica (1887), fuera en diversas ocasiones ninguneada en las dos acepciones del vocablo. Analizamos también distintos posicionamientos adoptados por miembros del colectivo científico decimonónico en relación a esa monografía y a su autor, finalizando con la valoración de la misma.

The Royal Academy of Exact, Physical and Natural Sciences of Madrid awarded the work titled Aves de España. (Un dato más), submitted it to public tender in 1882. The report was written by José Arévalo Baca, the 19th century Spanish ornithologist most recognized on a European scale and Head Professor at the University of Valencia since 1877. During the review process, the Natural Sciences Section of the Academy, referee of the Memory, indicated that the author had used the unpublished works of two professors from Malaga and Valencia, both deceased, without citing their names: Higinio Aragoncillo del Villar y Rafael Cisternas Fontseré. These criticisms were refuted by Arévalo with arguments and unpublished data that show here. However, in spite of his defense, Arévalo’s ornithological memory published in (1887) was, in several occasions willfully ignored. Likewise, we analyze stance of members of the 19th century scientific collective towards Arévalo’s monograph and Arévalo himself. We finish our study with a current, assessment of the Arévalo’s work.
Desenfado (e incluso humor) en la nomenclatura de taxones paleontológicos y zoológicos
Authors: Gutiérrez-Marco Juan Carlos
Published: January 2021

Resumen
Se presenta una recopilación de más de un millar de taxones de nivel género o especie, de los que 486 corresponden a fósiles y 595 a organismos actuales, que fueron nombrados a partir de personajes reales o imaginarios, objetos, compañías comerciales, juegos de palabras, divertimentos sonoros o expresiones con doble significado. Entre las personas distinguidas por estos taxones destacan notablemente los artistas (músicos, actores, escritores, pintores) y, en menor medida, políticos, grandes científicos o divulgadores, así como diversos activistas. De entre los personajes u obras de ficción resaltan los derivados de ciertas obras literarias, películas o series de televisión, además de variadas mitologías propias de las diversas culturas. Los taxones que conllevan una terminología erótica o sexual más o menos explícita, también ocupan un lugar destacado en estas listas. Obviamente, el conjunto de estas excentricidades nomenclaturales, muchas de las cuales bordean el buen gusto y puntualmente rebasan las recomendaciones éticas de los códigos internacionales de nomenclatura, representan una ínfima minoría entre los casi dos millones de especies descritas hasta ahora.
Abstra ct
A compendium of more than a thousand genera and species, of which 486 correspond to fossils and 595 to current organisms is presented. These were named after real or imaginary characters, objects, commercial companies, puns, or double entendres. Among the people distinguished by these taxa are artists (musicians, actors, writers, painters) and, to a lesser extent, politicians, great scientists or popularizers, as well as various activists. Among fictional characters, those derived from certain literary works, movies or television series stand out, in addition to various mythologies typical of different cultures. Taxa that carry a more or less explicit erotic or sexual terminology also figure prominently in these lists. Obviously, all of these nomenclatural excentricities, many of which are on the verge of bad taste and occasionally exceed the ethical guidelines of international codes of nomenclature, only constitute a minority among the over two million species described to date.

DEGRADATION OF HUMAN VALUES IN HIGHER EDUCATION: AN ANALYSIS
Authors: Gupta Pallavi
Published: January 2021

Values are defined most oftenly as standards for determining levels of goodness or desirability. Values are generally loaded with affective thoughts about ideas, objects, behavior etc. India’s higher education system is one of the oldest systems of the world. In spite of this there is no uniform expansion & development in this field. Our primordial embodiments i.e. Dharma, Artha, Kama, Moksha, on which education was based, are not even completely realized by scholars today. This is the main reason for degrading the level of human values in higher education in India. On one hand, people are getting rich by the degrees full of knowledge about various fields, simultaneously, loosing values and ethics etc. We ourselves are to be blamed for this. Our existing environment including family system, education system and media including newspapers, T.V. etc is responsible for such poor conditions. This research paper aims at explaining the factors how & why human values are consistently degrading in India, as the time passes, although we are rich in culture & traditions, still our higher education is unable to cherish or enhance it.
PERANCANGAN PENGOLAHAN AIR BERSIH TENAGA SURYA PORTABLE KAPASITAS 15 M3/HARI (Dengan Menggunakan Proses Ultrafiltrasi)
Authors: Setiaji Galih , Miranda Muhamad
Published: January 2021

Krisis air bersih masih sering melanda Indonesia terutama di daerah-daerah terpencil. Krisis air bersih ini bukan berarti tidak ada air, namun air yang ada tidak dapat digunakan untuk kebutuhan sehari-hari karena kondisinya yang tercemar. Hal ini dijumpai pada saat musim hujan di mana daerah yang terkena bencana seperti banjir, tanah longsor, gempa bumi, memiliki kondisi air yang tercemar dengan tanah dan kotoran lainya. Berbagai upaya telah dilakukan oleh pemerintah untuk mengatasi adanya krisis air seperti ini. Salah satu upaya yang dapat dilakukan adalah dengan mengadakan peralatan sistem pengolahan air. Namun beberapa kendala yang dihadapi adalah tidak adanya pasokan listrik yang di gunakan untuk menjalankan sistem pengolahan air. Genset sebagai alternative pun masih kurang layak karena membutuhkan pasokan BBM yang langka di daerah terpencil atau daerah bencana. Alternatif sumber energi lain yang dapat digunakan adalah energi surya. Saat ini telah banyak produk-produk sistem pembangkit tenaga surya (PLTS) di pasaran. Dengan menggunakan PLTS, sistem pengolahan air dapat bekerja tanpa membutuhkan biaya operasional karena listrik langsung didapatkan dari energi surya. Dalam paper ini telah dirancang sistem pengolahan air teknologi ultrafiltrasi tenaga surya. Teknologi ultrafiltrasi ini mampu mengolah air kotor menjadi air bersih secara instan dan selanjutnya digunakan untuk kebutuhan konsumsi. Lebih lanjut membran ultrafiltrasi dapat di-backwash sehingga kualitas membran dapat bertahan lama. Pada paper ini telah dirancang sistem dengan kapasitas 15 m3/hari. Kata Kunci : Ultrafiltrasi, PLTS, krisis air, bencana.

Untuk memprediksi kualitas air sungai Ciliwung, telah dilakukan pengolahan data-data hasil pemantauan secara Online Monitoring dengan menggunakan Metode Data Mining. Pada metode ini, pertama-tama data-data hasil pemantauan dibuat dalam bentuk tabel Microsoft Excel, kemudian diolah menjadi bentuk Pohon Keputusan yang disebut Algoritma Pohon Keputusan (Decision Tree) mengunakan aplikasi WEKA. Metode Pohon Keputusan dipilih karena lebih sederhana, mudah dipahami dan mempunyai tingkat akurasi yang sangat tinggi. Jumlah data hasil pemantauan kualitas air sungai Ciliwung yang diolah sebanyak 5.476 data. Hasil klarifikasi dengan Pohon Keputusan, dari 5.476 data ini diperoleh jumlah data yang mengindikasikan sungai Ciliwung Tidak Tercemar sebanyak 1.059 data atau sebesar 19,3242%, dan yang mengindikasikan Tercemar sebanyak 4.417 data atau 80,6758%. Selanjutnya data-data hasil pemantauan ini dievaluasi menggunakan 4 Opsi Tes (Test Option) yaitu dengan Use Training Set, Supplied Test Set, Cross-Validation folds 10, dan Percentage Split 66%. Hasil evaluasi dengan 4 opsi tes yang digunakan ini, semuanya menunjukkan tingkat akurasi yang sangat tinggi, yaitu diatas 99%. Dari data-data hasil peneltian ini dapat diprediksi bahwa sungai Ciliwung terindikasi sebagai sungai tercemar bila mereferensi kepada Peraturan Pemerintah Republik Indonesia nomor 82 tahun 2001 dan diketahui pula bahwa penggunaan aplikasi WEKA dengan Algoritma Pohon Keputusan untuk mengolah data-data hasil pemantauan dengan mengambil tiga parameter (pH, DO dan Nitrat) adalah sangat akuran dan tepat. Kata Kunci : Kualitas air sungai, Data Mining, Algoritma Pohon Keputusan, Aplikasi WEKA.
