Pengaruh Aplikasi Asap Cair Tempurung Kelapa terhadap Pertumbuhan dan Hasil Padi Gogo
Padi merupakan tanaman pangan utama di negara Indonesia karena sebagian besar penduduk Indonesia mengkonsumsi padi sebagai makanan pokok mereka. Kebutuhan beras terus meningkat seiring dengan meningkatnya jumlah pendudukan indonesia. Luas areal padi gogo yang rendah disebabkan oleh produktivitas dan kualitas hasil yang rendah. Rendahnya produksi padi dalam negeri juga dapat diakibatkan oleh adanya serangan hama dan penyakit. Salah satu teknik budidaya untuk mengurangi adanya serangan hama dan penyakit merupakan salah satu upaya perlindungan tanaman adalah dengan cara pemberian asap cair tempurung kelapa pada tanaman. Asap cair tidak berbahaya bagi kesehatan manusia dan ramah lingkungan. Selain itu, asap cair bermanfaat sebagai pencegah penyakit
tanaman dan dapat mempercepat pertumbuhan tanaman. Saat ini manfaat asap cair tempurung kelapa di bidang pertanian sebagai pengganti hormon dan pestisida belum banyak diketahui. Untuk itu perlu dilakukan pengujian aplikasi asap cair yang menyangkut dosis/konsentrasi dan cara penggunaannya. Penelitian ini bertujuan untuk mengetahui: (1) Respon beberapa varietas padi gogo terhadap aplikasi asap cair tempurung kelapa; (2) Pengaruh konsentrasi asap cair tempurung kelapa terhadap pertumbuhan dan hasil padi gogo; (3) Varietas padi gogo dan konsentrasi asap cair tempurung kelapa yang mampu menghasilkan pertumbuhan dan hasil optimum.
Penelitian ini dilaksanakan di desa cendana kecamatan kutasari Kabupate Purbalingga pada bulan april-september 2016. Penelitian menggunakanrancangan split plot dengan petak utama merupakan varietas padi gogo yaitu Situ Bagendit, inpago unsoed i dan situ patenggang, serta anak petak merupakan konsentrasi asap cair tempurung kelapa yaitu actk 0, actk 1:100 dan actk 1:200. Kombinasi perlakuan yang diperoleh sebanyak sembilan unit dan diulang tiga kali sehingga ada 27 unit percobaan. Variabel yang diamati antara lain: tinggi tanaman, jumlah daun, luas daun, bobot kering tajuk dan akar vegetatif, jumlah anakan, jumlah malai per rumpun, jumlah gabah isi per rumpun, bobot gabah isi per rumpun, jumlah gabah hampa per rumpun, bobot gabah hampa per rumpun, bobot gabah 1000 biji, panjang malai, bobot petak efektif dan bobot per hektar. Data dianalisis menggunakan uji f, apabila terdapat keragaman dilanjuktan dengan uji dmrt pada taraf kepercayaan 95%, sedangkan untuk mendapatkan konsentrasi optimum asap cair tempurung kelapa, maka dilakukan uji regresi.
Hasil penelitian menunjukkan bahwa pertumbuhan dan hasil yang terbaik ditunjukkan oleh varietas situ patenggang. Aplikasi asap cair tempurung kelapa (actk) mampu meningkatkan luas daun, bobot kering akar vegetatif, jumlah gabah isi per rumpun, bobot gabah isi per rumpun dan bobot gabah 1000 biji. Pertumbuhan dan hasil yang paling optimum ditunjukkan oleh varietas Situ Patenggang pada aplikasi actk konsentrasi 1:100
Lula, IrĂŁ e a mĂdia: uma análise da declaração de TeerĂŁ
Analisa a cobertura jornalĂstica da Declaração de TeerĂŁ, o acordo para o programa nuclear iraniano negociado por Brasil e Turquia em 17/05/2010. Os jornais analisados sĂŁo Folha de S. Paulo, Estado de S. Paulo e O Globo, numa tentativa de desvendar erros e acertos encontrados na cobertura jornalĂstica (em reportagens, editoriais e análises) dos trĂŞs jornais, no perĂodo compreendido entre 17/05/2010 e 31/05/2010. Como sustentação teĂłrica da avaliação, serĂŁo abordados os aspectos da Declaração de TeerĂŁ, as mudanças na geopolĂtica mundial, a polĂtica externa do governo de Luiz Inácio Lula da Silva e a ideologia do lulismo. TambĂ©m serĂŁo discutidas as dificuldades de diálogo entre Ocidente e Oriente, a desconfiança acerca do programa nuclear iraniano e as possĂveis consequĂŞncias caso o IrĂŁ consiga obter a tecnologia para fabricação de bombas nucleares
A Case Tracking System with Electronic Medical Record Integration to Automate Outcome Tracking for Radiologists
Radiologists make many diagnoses, but only sporadically get feedback on the subsequent clinical courses of their patients. We have created a web-based application that empowers radiologists to create and maintain personal databases of cases of interest. This tool integrates with existing information systems to minimize manual input such that radiologists can quickly flag cases for further follow-up without interrupting their clinical work. We have integrated this case-tracking system with an electronic medical record aggregation and search tool. As a result, radiologists can learn the outcomes of their patients with much less effort. We intend this tool to aid radiologists in their own personal quality improvement and to increase the efficiency of both teaching and research. We also hope to develop the system into a platform for systematic, continuous, quantitative monitoring of performance in radiology

A robust and efficient approach to detect 3D rectal tubes from CT colonography
Purpose: The rectal tube (RT) is a common source of false positives (FPs) in computer-aided detection (CAD) systems for CT colonography. A robust and efficient detection of RT can improve CAD performance by eliminating such “obvious” FPs and increase radiologists’ confidence in CAD. Methods: In this paper, we present a novel and robust bottom-up approach to detect the RT. Probabilistic models, trained using kernel density estimation on simple low-level features, are employed to rank and select the most likely RT tube candidate on each axial slice. Then, a shape model, robustly estimated using Random Sample Consensus (RANSAC), infers the global RT path from the selected local detections. Subimages around the RT path are projected into a subspace formed from training subimages of the RT. A quadratic discriminant analysis (QDA) provides a classification of a subimage as RT or non-RT based on the projection. Finally, a bottom-top clustering method is proposed to merge the classification predictions together to locate the tip position of the RT. Results: Our method is validated using a diverse database, including data from five hospitals. On a testing data with 21 patients (42 volumes), 99.5% of annotated RT paths have been successfully detected. Evaluated with CAD, 98.4% of FPs caused by the RT have been detected and removed without any loss of sensitivity. Conclusion: The proposed method demonstrates a high detection rate of the RT path, and when tested in a CAD system, reduces FPs caused by the RT without the
loss of sensitivity
Hole Hopping Across a Protein-Protein Interface.
We have investigated photoinduced hole hopping in a Pseudomonas aeruginosa azurin mutant Re126WWCuI, where two adjacent tryptophan residues (W124 and W122) are inserted between the CuI center and a Re photosensitizer coordinated to a H126 imidazole (Re = ReI(H126)(CO)3(dmp)+, dmp = 4,7-dimethyl-1,10-phenanthroline). Optical excitation of this mutant in aqueous media (//(CuII)' back ET that occurs over 12 Å, in contrast to the 23 Å, 120 us step in Re126WWCuI. Importantly, dimerization makes Re126FWCuI photoreactive and, in the case of {Re126WWCuI}2, channels the photoproduced "hole" to the molecule that was not initially photoexcited, thereby shortening the lifetime of ReI(H126)(CO)3(dmp•-)//CuII. Whereas two adjacent W124 and W122 indoles dramatically enhance CuI->*Re intramolecular multistep ET, the tryptophan quadruplex in {Re126WWCuI}2 does not accelerate intermolecular electron transport; instead, it acts as a hole storage and crossover unit between inter- and intramolecular ET pathways. Irradiation of {Re126WWCuII}2 or {Re126FWCuII}2 also triggers intermolecular *Re////(W122•+)' intermolecular charge recombination. Our findings shed light on the factors that control interfacial hole/electron hopping in protein complexes and on the role of aromatic amino acids in accelerating long-range electron transport
