Comparison of COCO and ChemCAD chemical simulation programs
No full textSzakdolgozatom elkészítése során az volt a feladatom, hogy összehasonlítsam a COCO és ChemCAD vegyipari szimulációs programokat. A dolgozatom első részében bemutatom a programokat, hogy pontosan milyen funkciói vannak, valamint vegyipari felhasználásait irodalmak alapján gyűjtött információkból. Ezek a programok fontos szerepet játszanak a modern vegyiparban, mivel számos kihívásokkal szembesülnek az emberek a mérnöki munkavégzés során, az üzem hatékonyságának javítása és a termelékenység növelése érdekében. A dolgozatom második részében fontos volt, hogy megnézzem a gyakorlati alkalmazásait a COCO és ChemCAD szimulációs programoknak külön-külön, valamint az összehasonlítását egy vegyipari szimuláción belül. A szimuláció, amit be mutatok a napjainkba elég nagy jelentőséggel bíró ammóniaszintézis lesz.Az ammóniaszintézist mindkét szimulációs programmal megcsináltam.LBVegyészmérnök BscBSc/B
Estudo da adsorção de cobre (II) usando como adsorvente pó da casca de coco verde ativada com hidróxido de sódio
No full textTCC (graduação) - Universidade Federal de Santa Catarina, Centro de Ciências Físicas e Matemáticas, Curso de Química.A poluição por metais pesados vem se tornando um sério problema ambiental. O uso de biomassas como adsorvente para a remoção de metais tóxicos de efluentes industriais aparece como uma alternativa promissora às tecnologias existentes. Dentro deste contexto surge a casca de coco verde, que pode ser utilizada como adsorvente apresentando como uma vantagem o baixo custo do material. O objetivo deste trabalho de conclusão de curso foi determinar a capacidade de adsorção de cobre (II) pela casca de coco verde tratada com NaOH 0,1 mol L-1. No processo de adsorção foram avaliados o efeito do pH na adsorção, o mecanismo cinético de adsorção, o equilíbrio de adsorção, e a dessorção do metal. Observou-se que a adsorção de cobre (II) é dependente do pH da solução e a quantidade máxima adsorvida ocorreu em pH 6,0. O estudo cinético revelou que o equilíbrio foi atingido em 9 horas. Os modelos cinéticos de pseudo primeira-ordem, pseudo segunda-ordem e difusão intrapartícula, em suas formas linearizadas, foram testados para avaliar o mecanismo cinético que controla o processo de adsorção. Verificou-se que o modelo de pseudo segunda-ordem foi o que melhor correlacionou os dados experimentais. Obtiveram-se boas percentagens de remoção para o cobre (II), sendo que, em concentrações inicias inferiores a 100 mg g-1 foram obtidas percentagens de remoção entre 40 a 96,1%. Para a interpretação dos dados de equilíbrio de adsorção, foram utilizados os modelos de isoterma de Langmuir e Freundlich. A análise dos resultados permitiu concluir que o modelo de isoterma de Langmuir forneceu o melhor ajuste dos dados experimentais para o sistema estudado. A capacidade máxima de adsorção (qm ) observada para o adsorvente foi de 13,04 mg g-1. O estudo de dessorção do íon metálico cobre (II), foi realizado com soluções eluentes de HNO3 e EDTA em diferentes concentrações, e revelou que a melhor performance de dessorção de cobre (II) ocorreu com solução de EDTA. Os resultados apresentados mostram que a casca de coco verde apresenta as características apropriadas para o processo de adsorção de cobre (II) e que pode ser utilizada como uma alternativa de descontaminação de efluentes
A Guide to CoCo
No full textCoCo is a program for estimation, test and model search among hierarchical interaction models for large complete contingency tables. The name CoCo is derivated of "Co"mplete "Co"ntingency tables, since the initial program could only handle complete tables, but the program has been enhanced to handle incomplete tables. CoCo works especially efficiently on graphical models, and some of the commands are designed to handle graphical models.

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
PENGGANTIAN PEPTON OLEH PUPUK NPKDALAM PRODUKSI NATA DE COCO(Penelitian Eksperimental Laboratorik)
No full textPenelitian ini dirancang untuk mengetahui efek suplementasi pupuk NPK terhadap produk nata de coco. Pupuk NPK mungkin dapat digunakan untuk mengganti pepton dalam membuat nata de coco. Penelitian ini dilakukan di Laboratorium Biology Universitas Muhammadiyah Malang dengan menggunakan rancangan penelitian ekperimental, yaitu rancangan acak lengkap dan pembuatan nata de coco menggunakan formula Agus Krisno (1999). Penelitian ini menggunakan konsentrasi suplementasi pupuk NPK 0,0%; 0,1%; 0,2%; 0,3%; dan 0,4%b/v. Data yang terkumpul dianalisis dengan analisis variansi satu jalur. Berdasarkan temuan penelitian dan analisis data yang dilakukan, dapat disimpulkan bahwa: 1) ada perbedaan pengaruh yang sangat nyata konsentrasi suplementasi pupuk NPK terhadap ketebalan dan berat basah nata de coco, 2) Konsentrasi suplementasi pupuk NPK 0,3%b/v merupakan konsentrasi yang paling baik pengaruhnya terhadap produk nata de coco untuk indikator ketebalan dan berat basah. Akhirnya disarankan untuk menggunakan konsentrasi suplementasi pupuk NPK 0,3%b/v untuk membuat nata de coco sebagai pengganti pepton

No full textMeasurement of the ratio of branching fractions B(B0→K∗0γ )/B(B0s→φγ ) and the directCP asymmetry inB 0→K∗0γ
No full textThe ratio of branching fractions of the radiative B decays B0→K⁎0γ and B0s→ϕγ has been measured using an integrated luminosity of 1.0 fb−1 of pp collision data collected by the LHCb experiment at a centre-of-mass energy of s√=7TeV. The value obtained is
B(B0→K⁎0γ)B(B0s→ϕγ)=1.23±0.06(stat.)±0.04(syst.)±0.10(fs/fd),
where the first uncertainty is statistical, the second is the experimental systematic uncertainty and the third is associated with the ratio of fragmentation fractions fs/fd. Using the world average value for B(B0→K⁎0γ), the branching fraction B(B0s→ϕγ) is measured to be (3.5±0.4)×10−5.
The direct CP asymmetry in B0→K⁎0γ decays has also been measured with the same data and found to be
ACP(B0→K⁎0γ)=(0.8±1.7(stat.)±0.9(syst.))%.
Both measurements are the most precise to date and are in agreement with the previous experimental results and theoretical expectations
