Combinação entre turfa vermelha e areia na obtenção de substrato-inóculo do fungo micorrízico arbuscular Glomus clarum.

O objetivo com o presente estudo foi verificar a influência de diferentes proporções de turfa vermelha e areia na composição do substrato sobre a colonização radicular por fungos micorríozicos arbusculares (FMA) e no desenvolvimento vegetativo de aveia branca. O experimento foi conduzido em casa de vegetação e os tratamentos foram constituídos a partir de combinações de turfa vermelha (T) e areia (A): 100%A; 25%T+75%A; 50%T+50%A; 75%T+25%A; 100%T. Dez sementes de aveia foram emeadas por vaso plástico preto (350ml de volume), contendo 5 gramas de inóculo de Glomus clarum. Quarenta e três dias após a semeadura da aveia, foram realizadas avaliações de desenvolvimento vegetativo e colonização micorrízica do sistema radicular das plantas, através da presença de estruturas, como hifas, arbúsculos e vesículas. Substratos com maior quantidade de turfa induziram maior desenvolvimento da parte aérea e maior qualidade de raízes (QR), em termos de volume de raízes. Entretanto, a presença da turfa acima de 50% no substrato diminuiu a percentagem de colonização micorrízica da aveia. A similaridade verificada entre as curvas de regressões de percentagem de colonização e Água Facilmente Disponível, com mesmo ponto de máximo, sugerem que a quantidade de mesoporos resultante da combinação turfa/areia influencia na resposta dos FMA, a melhor resposta é obtida em mistura com 32,5% de turfa vermelha

MUSIK TALEMPONG GRUP MUDA MUDI GONJONG LIMO PADA UPACARA PERNIKAHAN ADAT MINANGKABAU DI BANDUNG

Penelitian ini diwujudkan dalam bentuk skripsi dengan judul “Musik Talempong grup Muda Mudi Gonjong Limo pada Upacara Pernikahan Adat Minangkabau di Bandung”. Musik talempong merupakan musik tradisional Minangkabau. Dalam perkembangannya terdapat beberapa jenis musik talempong yaitu musik talempong pacik dan musik talempong kreasi. Alasan penelitian ini dilakukan yaitu meskipun suku Minangkabau yang berada di Jawa Barat khususnya kota Bandung merupakan kaum minoritas di antara suku Sunda akan tetapi dengan semangat yang tinggi mereka tetap menjaga budaya warisan leluhur dan mempertahankan eksistensi budayanya dengan salah satunya melalui pengembangan musik talempong. Penelitian ini bertujuan untuk mendeskripsikan fungsi, instrumentasi musik dan teknik permainan musik talempong yang ditampilkan pada upacara pernikahan adat Minangkabau di Bandung. Subjek penelitian ini adalah grup Muda Mudi Gonjong Limo yang terdiri dari lima orang laki-laki dan dua orang perempuan sebagai pemain musik talempong. Metode yang digunakan yaitu metode deskriptif analisis dengan pendekatan kualitatif. Berdasarkan penelitian yang telah dilakukan, peneliti memperoleh fungsi, instrumen yang digunakan dan teknik permainan musik talempong pada upacara pernikahan adat Minangkabau di Bandung.;--- This study is made in the form of a mini thesis with the title “Talempong Music of Muda Mudi Gonjong Limo Group at Minangkabau Wedding Ceremony in Bandung”. Talempong music is a traditional music of Minangkabau. In its development, there are some types of talempong music, such as talempong pacik music and talempong kreasi music. The purpose of this study is that despite Minangkabau tribes who live in West Java, particulary in Bandung a minority among the Sundanese tribe, they keep the cultural heritage in a high spirits and maintaining their cultural existence by developing the talempong music. The aim of this study is to describe the function, the instrumentation and the technique of playing talempong music which performed in the traditional wedding ceremony of Minangkabau in Bandung. The subject of the study is MMGL group consisting of five men and two women as talempong music player. The music method used is descriptive analysis method with a qualitative approaching. Based on the study that has been done, the researcher gain the function, the instrument used and the technique of playing talempong music in the traditional wedding ceremony of Minangkabau in Bandung

DNA and Etruscan identity

From the time of Herodotus, who suggested that the Etruscans were immigrants to Italy, to the present day, the origin of the Etruscans has been debated. Since the mid-twentieth century a convincing academic consensus has been built that the Etruscans were an autochthonous people. The development of molecular archaeology, investigating ancient biological molecules, particularly DNA, has brought new evidence to the debate. This area is still developing and many of its findings are experimental or provisional

Coreference Resolution System for Indonesian Text with Mention Pair Method and Singleton Exclusion using Convolutional Neural Network

Neural network has shown promising performance on coreference resolution systems that uses mention pair method. With deep neural network, it can learn hidden and deep relations between two mentions. However, there is no work on coreference resolution for Indonesian text that uses this learning technique. The state-of-the-art system for Indonesian text only states the use of lexical and syntactic features can improve the existing coreference resolution system. In this paper, we propose a new coreference resolution system for Indonesian text with mention pair method that uses deep neural network to learn the relations of the two mentions. In addition to lexical and syntactic features, in order to learn the representation of the mentions words and context, we use word embeddings and feed them to Convolutional Neural Network (CNN). Furthermore, we do singleton exclusion using singleton classifier component to prevent singleton mentions entering any entity clusters at the end. Achieving 67.37% without singleton exclusion, 63.27% with trained singleton classifier, and 75.95% with gold singleton classifier on CoNLL average F1 score, our proposed system outperforms the state-of-the-art system

Cross-correlation trajectory study of V-V energy transfer in HF-HF and DF-DF

Results of a fully three‐dimensional classical trajectory calculation of vibrational energy transfer are presented for the collision of HF(v=1) with HF(v=1) and its deuterium analog. A cross‐correlation method, together with quasiclassical trajectories, is introduced to relate the changes in vibrational states of the two molecules to probabilities and rate constants. Multiple collisions are found to make an important contribution to the vibrational energy transfer cross‐sections for the present potential surface. Vibrational anharmonicity is shown to decrease the energy transfer rate constant by a factor of ten, by causing the process to be further from exact resonance. Excellent agreement with experiment is obtained for the HF–HF and DF–DF systems

Rotational energy transfer in hydrogen halide molecules at supersonic beam velocities

Rotational energy transfer cross sections are calculated for HCl–HCl and HCl–HF collisions using classical trajectories. The exponential model for the rotational results is compared with transitions j-->j[prime] in collisions of a supersonic HCl molecular beam with a thermal beam. Reasonable agreement with the functional form of that model is obtained. The trajectory results indicate that some modification is needed in the exponential formula, to account for microscopic reversibility in rotor–rotor collisions. Using a simple intermolecular potential without adjustable parameters, in which the only anisotropic terms are of the dipolar and dispersion type (i.e., long range), reasonable agreement is obtained with the experimental constant for HCl–HCl in the exponential. Calculations are also described for HCl–HI and HCl–HBr collisions. Microscopic reversibility for the averaged cross sections is discussed in connection with the exponential model
