Forage, the main feedstuff for ruminants, includes grasses and legumes, browses, and side products of food crops. However, legumes generally have greater crude protein content relative to other species of forage plants. One of the species of legumes is alfalfa (Medicago sativa), a perennial crop that can grow from the tropics up to sub tropics. In spite of its excellent nutrient content, In Indonesia alfalfa is still not widely explored and used for feedstuff. A study was conducted to explore and evaluate of alfalfa performances in terms of the height, number of tillers, dry matter (DM) and crude protein (CP) productions under the effects of different plant densities and ages of defoliation”. The height of the location of study was 200 m above sea level with an average temperature of 270 C. The results showed that the ranges of the height of alfalfa, the numbers of tillers, DM and CP productions were 33.31-56.32 cm, 36.38-82.36 tillers/bunch, 556.9-1018.9 kg/ha/defoliation, and 149.75 – 291.79 kg/ha/defoliation, respectively. In general, the ages of plant at the time of defoliation and plant distances affected (P<0.05) the variables being studied. The older plants resulted in greater DM and CP yields, and more densely plantation resulted in greater DM and CP yields.Keywords: alfalfa, plant density, defoliation age.

Efisiensi Big Data Menggunakan Improved Nearest Neighbor
Authors: Bawono Aditya Hari , Supianto Ahmad Afif
Published: December 2019

Klasifikasi adalah salah satu metode penting dalam kajian data mining. Salah satu metode klasifikasi yang populer dan mendasar adalah k-nearest neighbor (kNN). Pada kNN, hubungan antar sampel diukur berdasarkan tingkat kesamaan yang direpresentasikan sebagai jarak. Pada kasus mayoritas terutama pada data berukuran besar, akan terdapat beberapa sampel yang memiliki jarak yang sama namun amat mungkin tidak terpilih menjadi tetangga, maka pemilihan parameter k akan sangat mempengaruhi hasil klasifikasi kNN. Selain itu, pengurutan pada kNN menjadi masalah komputasi ketika dilakukan pada data berukuran besar. Dalam usaha mengatasi klasifikasi data berukuran besar dibutuhkan metode yang lebih akurat dan efisien. Dependent Nearest Neighbor (dNN) sebagai metode yang diajukan dalam penelitian ini tidak menggunakan parameter k dan tidak ada proses pengurutan sampel. Hasil percobaan menunjukkan bahwa dNN dapat menghasilkan efisiensi waktu sebesar 3 kali lipat lebih cepat daripada kNN. Perbandingan akurasi dNN adalah 13% lebih baik daripada kNN.

Abstract

Classification is one of the important methods of data mining. One of the most popular and basic classification methods is k-nearest neighbor (kNN). In kNN, the relationships between samples are measured by the degree of similarity represented as distance. In major cases, especially on big data, there will be some samples that have the same distance but may not be selected as neighbors, then the selection of k parameters will greatly affect the results of kNN classification. Sorting phase of kNN becomes a computation problem when it is done on big data. In the effort to overcome the classification of big data a more accurate and efficient method is required. Dependent Nearest Neighbor (dNN) as method proposed in this study did not use the k parameters and no sample at the sorting phase. The proposed method resulted in 3 times faster than kNN. The accuracy of the proposed method is13% better results than kNN.

«Quiero despertarlos»
Authors: Fernández Francisco González
Published: December 2019

La vida de Artaud fue un periplo por las instituciones mentales que dejó profundas huellas en su concepción artística. Desde que entró en contacto con el cuerpo médico y se relacionó con sus psiquiatras se apropió del lenguaje y de las técnicas de estos, llegando a atribuir al poeta la función de terapeuta de una sociedad enferma y decadente a la que solo un arte que recurriera a una crueldad funcional podría curar. Operación quirúrgica, peste y descargas eléctricas son algunas de las metáforas a las que recurrirá para ilustrar la manera de despertar a un público que parecía haber sido hipnotizado por el diabólico doctor Caligari o por su avatar, Adolf Hitler. La figura del Fürher, a quien Artaud siempre afirmó haber conocido personalmente, constituyó para él una especie de doble siniestro que parecía haber desvirtuado sus propias ideas sobre el Teatro de la Crueldad. Frente a unos espectáculos hipnóticos que predisponían a las masas a aceptar una política higienista, racial y eugenésica de una crueldad desconocida, Artaud buscó en la medicina los medios para sanar a una colectividad que había perdido el sentido de la vida y cuyos individuos vagaban por el mundo como si fueran sonámbulos.

Este artículo expone tres conceptos-clave, los de interartisticidad, interdiscursividad e intersemioticidad, que permiten desplazar los estudios relacionales del arte y de la literatura desde el dominio del comparatismo en el que, con vocación culturalista y hermenéutica, se cultiva principalmente la búsqueda de fuentes e influencias y la interpretación de las obras, hasta el de la semiótica donde, con voluntad científica, se prefiere el análisis y la construcción de teorías transversales, de validez general para todo el campo simbólico.
La ecopoesía de Nicanor Parra como espacio de disentimiento
Authors: Rosa Sofía
Published: December 2019

Desde la década del cincuenta se desarrolla en Chile una línea de ensayistas y poetas ecologistas que denuncia el modelo depredador de crecimiento económico y hace un llamado a la acción colectiva. La publicación de Ecopoemas del poeta chileno Nicanor Parra en 1982 constituye un hito fundamental que recupera el pensamiento ecologista de varios autores anteriores, al tiempo que propone nuevos paradigmas ético-estéticos capaces de articular subjetividades disidentes en los tres registros ecológicos (Guattari).
Con este trabajo me propongo estudiar los ecopoemas como un espacio agonista del disentimiento. El trabajo se centra en la pregunta por los modos en que la ecopoesía de Nicanor Parra configura una performatividad y afectividad del disentir político. Así, primero analizo cómo la ecología se construye como un discurso de resistencia instalado política y estéticamente como oposicional; segundo, describo cómo este discurso configura un nosotros ecocéntrico en el que nuevos actores serán capaces de producir los afectos y los gestos del disentir político que promete una acción colectiva. Por último, reflexiono en torno a la vigencia de la propuesta de Parra en el contexto de la Ecología Política latinoamericana.

Psoriasis patients with comorbid depression represent a common therapeutic challenge for dermatologists. Depressed patients often require the practicing dermatologist to go outside of their comfort zone, and the FDA’s labeling of medications such as brodalumab have further complicated an already difficult-to-treat patient population. A multi-disciplinary work-group consisting of a board-certified psychiatrist, a licensed clinical psychologist, and multiple dermatologists was convened to formulate practical recommendations for the evaluation and treatment of this at-risk population. How to broach the subject of depression and when to refer patients for formal evaluation were discussed. The expert panel also produced a consensus statement regarding the use of brodalumab in patients with both psoriasis and depression.
Bilateral Porokeratosis Ptychotropica on the Gluteal Cleft: A Case Report and Review of the Literature
Authors: Nazarian Roya S. , Vyas Nikki , Scheinfeld Noah , Phelps Robert G.
Published: December 2019

Porokeratosis ptychotropica (PP) is a rare variant of porokoretosis that is distinctive based on its clinical presentation of pruritic, verrucous papules and plaques that often form a “butterfly” shape, commonly located on the perinatal cleft with extension to the buttocks. Similar to other variants of porokeratosis, it is histologically distinguished by the presence of cornoid lamellae. Proper diagnosis is necessary as some studies suggest that PP may predispose to squamous cell carcinoma. Furthermore, there are limited evidence-based treatment options.We report the case of a47 year-old-male who presented with a rash on the buttocks and legs for 3 years. Physical exam revealed erythematous, annular, and verrucous plaques on the bilateral periglueteal area and bilateral distal lower extremities. The patient felt that lesions on the legs were disfiguring but otherwise asymptomatic. Biopsy results demonstrated hyperkeratosis and parakeratosis suggestive of cornoid lamellae. Clinical and histologic findings were suggestive of PP. Lesions on the legs were treated with cryotherapy, which resulted in resolution at a 3-month follow-up.PP remains a diagnostic and therapeutic challenge due to its rarity. No standard of care has been established, though topical calcipotriol, topical imiquimod, topical tretonoin, and cryotherapy have been used with success in the literature. This case highlights unique characteristics of PP in order to aid in early detection and cancer prevention while also describing various treatment modalities.

Published: December 2019

Autoimmunity Related Neutrophilic Dermatoses (ARND) is a recently described entity characterized by urticarial papules and plaques with histology showing a neutrophilic perivascular and interstitial infiltrates with leukocytoclasis, along with variable vacuolar interface dermatitis.  We report a 38 year old Caucasian female with a ten year history of lupus who presented with pruritic urticarial papules and plaques on the face, trunk, upper extremities and thighs.  The onset occurred 10 days after she started a calcium channel blocker (CCB), diltiazem. Histopathology revealed scattered dyskeratotic keratinocytes, vacuolar interface dermatitis, and a sparse perivascular and interstitial mixed infiltrate of neutrophils within the dermis. There was focal leukocytoclasis, dermal edema, and rare eosinophils.  The patient initially improved with prednisone taper, but flared again upon starting a different CCB, verapamil.  Exposure to certain medications such as CCB in the setting of autoimmune connective tissue disorder may be the inciting trigger for a neutrophilic dermatoses. Future studies may provide further information on the pathogenesis of ARND and cutaneous drug eruption in the setting of SLE.

This study aims to determine the water quality in the Klawing River, riparian vegetation, native and introduced fish, utilization, the presence of pollutant resources, fishing practices, and regional regulations related to the Klawing River. Research methods by surveying and searching libraries. The results showed that the condition of water quality in the Klawing River upstream was in good condition, while the middle and downstream parts had decreased. Riparian vegetation in the upper reaches is still dominated by trees compared to the middle and downstream. Along the Klawing River, there are still many locations that have the potential for erosion. There are 23 species of fish found along the Klawing River. Among these species, there are 16 species of native fish species and 7 species of introduced fish species. The source of pollution in the Klawing River comes from liquid waste and solid waste. Fishing is done by using fishing gear such as fishing rods, nets, stone cages, but there are still those who use drugs and stroom. Existing regulations on the Klawing River only refer to government regulations governing the river because it does not yet have a special PERDA.

Hydrogenases are microbial redox enzymes that catalyze H2 oxidation and proton reduction (H2 evolution). While all hydrogenases show high H2 oxidation activities, [FeFe]-hydrogenases are excellent H2 evolution catalysts as well. Their hydrogen-forming active site cofactor (“H-cluster”) comprises a [4Fe-4S] cluster covalently linked to a diiron site modified with CO and CN– ligands that tune the redox potential and anchor the cofactor within the protein. Two distinct proton transfer pathways connect the H-cluster and facilitate hydrogen turnover at low overpotential. In this study, we employ in situ ATR FTIR spectroscopy and spectro-electrochemistry to analyze the mechanics of hydrogen turnover in [FeFe]-hydrogenase. Titrating the proton concentration from pH 10 to pH 5 under H2 oxidation or H2 evolution conditions reveals the influence of site-selective protonation on the equilibrium of H-cluster redox states. Under H2 evolution conditions, protonation facilitates electron uptake at the [4Fe-4S] cluster and impedes premature reduction of the diiron site, the later which dominates at acidic pH values. This observation is discussed in the context of the natural pH dependence of H2 evolution as catalyzed by [FeFe]-hydrogenase.

In this 21st century education, preparing learners to have high order thinking skills (HOTS) is important to make them ready face the global era. HOTS (analyze, evaluate, create) is the continuous phases of LOTS (remember, understand, apply).  HOTS in a project based instruction is proposed to be able to promote the skills needed in the 4.0 era (critical thinking, communication, creativity, and collaboration). This research focused on a HOTS-based project in a mechanical engineering, Adisutjipto College of Technology. Based on the observation in the previous semester, the students needed to improve their HOTS that the research applied an action research study. The projects were allocated in two course objectives; identifying the tools in mechanical engineering and identifying the components of an airplane. They were chosen due to the supported authentic materials exist in the college workshop laboratory, hangar, and airplane museum near the college. The results were the learners enjoyed the learning and improved the engagement in a group work, the critical thinking in finding fruitful information, the creativity in creating presentation, and the speaking skill in presenting in front of other people.
La forêt comme lieu de mémoire et d’oubli dans Les aubes écarlates (2009) et La saison de l’ombre (2013) de Léonora Miano
Authors: Miller Robert , Onyeoziri Gloria
Published: December 2019

La forêt comme espace sacré figure dans plusieurs textes africains et antillais. Cette tradition permet à Léonora Miano de lancer une enquête sur l’importance et les limites de la mémoire culturelle. Dans Les aubes écarlates la forêt abrite un groupe rebelle qui promet un retour à une Afrique précoloniale glorieuse mais recèle aussi les esprits des disparus de la Traite qui rappellent le besoin de réapprendre une vision communautaire. Dans La saison de l’ombre, enquête sur les communautés décimées par la Traite, la forêt devient un lieu de questionnement sur la survie de la mémoire. La forêt de Miano reflète ainsi les espoirs et doutes d’une nouvelle génération.
Le lieu dans Un vent se lève qui éparpille : du pareil au même ?
Authors: Legault Suzanne
Published: December 2019

Cette lecture du roman Un vent se lève qui éparpille de Jean Marc Dalpé tient surtout compte de l’enchâssement des genres littéraires dans le cadre de ce récit. Leur analyse peut nous aider à préciser une des raisons pour lesquelles Marie et Marcel, lorsqu’ils en ont l’occasion, ne quittent pas le lieu du drame. Les personnages évoluent dans le nord de l’Ontario, paysage bien connu de l’auteur. Ce n’est pas pour autant une œuvre uniquement régionaliste. Dalpé voudrait convaincre les lecteurs/spectateurs que peu importe le lieu où habiteraient ses personnages, ils seraient toujours prisonniers d’une variante de la même histoire et ne pourraient s’évader de ce même contraignant, voire angoissant.

KAJIAN KARAKTERISTIK ALIRAN TERHADAP BANGUNAN PELIMPAH PADA SALURAN TERBUKA
Authors: Saleh Syam Sunniati , Musa Ratna , As'ad Hanafi
Published: December 2019

Pelimpah (Spillway) merupakan salah satu bangunan pelengkap dari bendungan yang berfungsi sebagai pengaman terhadap bahaya air banjir yang melimpas diatas bendungan (overtopping). Selain itu, bangunan pelimpah juga berfungsi agar debit hujan rancangan yang terjadi cepat mengalir sehingga debit air tidak sempat meluas. Karakteristik aliran yang melewati bangunan pelimpah akan tergantung kepada bentuk dan sifat pelimpah itu sendiri. Untuk kepentingan  bangunan air seperti bendungan dan bangunan air lainnya maka perihal karakteristik aliran sangatlah penting untuk menentukan bangunan yang akan dipilih sesuai kebutuhannya. Pengkajian tentang hal ini dapat dilakukan melalui suatu penelitian terhadap aliran pada saluran terbuka berukuran kecil yang melewati pelimpah dengan model bangunan pelimpah type ogee. Adapun tujuan dari penelitian ini yaitu untuk mengetahui karakteristik aliran, pola aliran dan energy spesifik yang terjadi pada bangunan tersebut. Pada penelitian ini dapat disimpulkan bahwa aliran air dapat mengalami perubahan ketinggian karena adanya bangunan pelimpah dan berpengaruh pada karakteristik alirannya. Dimana semakin tinggi muka air maka semakin besar kecepatan yang terjadi.Pola aliran pada daerah hulu merupakan aliran sub kritis (FR1) kemudian menjadi kritis (FR = 1) pada saat melewati bangunan pelimpah. Setelah melewati bangunan pelimpah maka aliran menjadi super kritis (FR 1) dan berangsur-angsur menjadi normal kembali pada saat berada di daerah hilir.Energi spesifik yang dihasilkan pada bangunan pelimpah tipe Ogee juga bergantung pada jenis pelimpah yang diberikan.

Published: December 2019

A estratégia de formação de monocamada automontada (SAM) mista para a imobilização de material biológico é atualmente utilizada na construção de biossensores, tanto para fins analíticos como para estudos de afinidade entre proteínas. Este trabalho aborda o estudo da formação, em tempo real, de SAM mista contendo ácido-11-mercaptoundecanóico (MUA) e o 6-mercapto-1-hexanol, na proporção de 1:3, sobre superfície de ouro utilizando as técnicas de QCM-D e voltametria cíclica. Por meio dos resultados, foi possível verificar que a SAM é um filme empacotado e rígido, apresentando elevado grau de cobertura superficial. Com exemplo de adsorção de proteína sobre a SAM, foi estudado, por QCM-D, o processo de adsorção utilizando gelatina. Os resultados evidenciam que esse processo ocorre em uma única etapa, culminando com a formação de uma monocamada de proteína.

Model collaborative teaching dipandang sebagai pembelajaran yang memungkinkan siswa terhindar dari rasa cemas yang berat ketika menyelesaikan soal, sehingga siswa dapat membangun pemahaman konsep dengan baik. Kecemasan yang berat dapat menyebabkan rendahnya pemahaman matematis pada siswa. Tujuan penelitian ini adalah untuk mengetahui tingkat kecemasan dan pemahaman matematis siswa melalui penggunaan collaborative teaching. Sampel terdiri dari 51 siswa SMP dari kelas VII MTsN Jeureula yang di tes dua kali selama dua bulan. Studi menemukan terdapat peningkatan pemahaman matematis siswa yang signifikan pada tes awal dan tes akhir. Terdapat perbedaan kemampuan pemahaman siswa yang diajarkan dengan collaborative teaching dan pembelajaran biasa, sementara tingkat kecemasan matematis, berada pada tingkat ideal (sedang) dibanding dengan siswa yang diajarkan dengan metode biasa yaitu berada pada tingkat berat. Studi juga menemukan tidak terdapat interaksi antara faktor pembelajaran dan pengetahuan awal siswa (Tinggi, sedang dan rendah) terhadap pemahaman konsep. Ini berarti bahwa model collaborative teaching dan pengetahuan awal siswa tidak mempengaruhi pemahaman matematis secara bersamaan. Akan tetapi, terdapat interaksi antara faktor pembelajaran dan pengetahuan awal siswa terhadap kecemasan matematis, ini berarti model collaborative teaching dan pengetahuan awal siswa mempengaruhi kecemasan matematis secara bersamaan.
Change of amino-acid composition of yak blood, depending on the season of the year
Authors: Ludu В. М.
Published: December 2019

The results of the comparative study of yak blood parameters by amino-acid composition depending on the season of the year are presented. The research was conducted in the Republic of Tuva. The object of research were adult female yaks after the fi rst or more calving. The studied animals were at the pasture in the highlands all year round. The material of the research was whole blood stabilized by heparin and yak serum. Blood was taken in spring and autumn from the jugular vein. The determination of blood biochemical parameters and the biometric processing of the results were carried out by generally accepted methods. 14 amino acids were revealed. Of these, seven are non-essential amino acids (asparagine, serine, glutamine, glycine, alanine, histidine, arginine) and seven are essential (threonine, valine, methionine, isoleucine, leucine, phenylalanine, lysine). The amino-acid content in the blood of yaks living in highlands under low partial pressure did not vary signifi cantly during the study period. The content of non-essential and essential amino acids was recorded in the ratio of 50 : 50, regardless of the season of the year. In autumn, compared to spring, serine content increased 2.43 times, asparagine –1.05 times, valine – 1.07, leucine – 1.07 times. An increase in phenylalanine in the autumn period may indicate its suffi cient content in grass eaten by yaks. Features of the interior indicators of yaks, common in the Republic of Tuva, are the result of their long year-round pasture maintenance in extreme climatic conditions of the highlands.
