Morphological, Structural, and Functional Properties of Maranta (Maranta arundinacea L) Starch.
No full textStarch isolated from maranta (Maranta
arundinacea) tuber and studied for its various physicochemical
characteristics. The amylose content of the starch
was 24.8%. SEM showed that the granules were small
indented and spherical. Maranta starch granule size has a
range of 2.92-6.42 μm, (mean of 4.84 μm), length/degree
of 1.20, and roundness of 0.73. Maranta starch has a
gelatinization temperature of 74.8oC, peak viscosity of 498
BU, and cold paste viscosity of 669 BU. It also possessed
higher freeze-thaw stability. Dynamic rheological properties
of maranta starch, measured using parallel plate geometry
showed increased storage modulus (G') values, while loss
modulus (G'') values were decreased with increasing frequency
values (0-100 Hz). The low gelatinization temperature and
high freeze thaw stability of starch indicates its potential
for application as a thickener in food industries

In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang 20 Oktober 2020. pp. xx. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Modification of Canna edulis and Maranta arundinacea starch through NaOH-Etanol was conducted to improve and expand the use of this starch in food industry, especially instant product. The objective of this study was to study the effect of the amount of NaOH on physicochemical characteristics of modified canna and maranta starches. This research used a Split Plot Design (RPB) with the main plot of type of tuber (canna and maranta) and a plot of the amount of NaOH added (0, 3, 6, 9) grams per 10 grams of starch. The observed parameter were whiteness level, yield, swelling power and solubility index, cold water-solubility, water absorption index, moisture content and ash content. The results showed that the type of tubers and the amount of NaOH significantly affected the whiteness level, cold water solubility, water absorption index, and water content. Maranta starch modified with 9 g NaOH was the best treatment with the value of water absorption index (IAA) is 203.95%
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
EVALUATION OF TOTAL PHENOLIC AND FLAVONOID CONTENTS AND IN VITRO ANTIOXIDANT ACTIVITY OF RHIZOME OF MARANTA
No full textABSTRACT In the present study, in vitro antioxidant and free radical scavenging capacity of methanol extract from Maranta arundinacea rhizome were evaluated using established in vitro models such as DPPH, hydroxyl radical, superoxide radical, ABTS radical cation and reducing power. Total phenolic and flavonoid contents were estimated. Methanol extract showed considerable in vitro antioxidant and free radical scavenging activities in a dose dependent manner when compared to the standard antioxidant (ascorbic acid/trolox). Thus, this study suggests that Maranta arundinacea rhizome can be as a potent source of natural antioxidant
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
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
Letter from R. R. Zellick, Assistant Trust Officer, Anglo California National Bank of San Francisco, to Joseph R. Goodman, October 2, 1942
No full textLetter from R. R. Zellick, Assistant Trust Officer at The Anglo California National Bank of San Francisco, to Joseph R. Goodman, regarding property owned by Dave Tatsuno. Zellick mentions a dispute between current tenants and Tatsuno, and that Tatsuno has asked Goodman to help locate trustworthy tenants.Personal correspondence, organizational records, government documents, publications, and other papers created or collected by Joseph R. Goodman documenting the forced removal and incarceration of Japanese Americans during World War II, as well as organized resistance to incarceration. Included in the collection are records of the Japanese Young Men's Christian Association and the Japanese American Citizens' League in San Francisco, including papers of the Japanese YMCA's executive secretary Lincoln Kanai; Sakai family papers; Goodman's correspondence to and from Japanese American incarcerees, organizations opposing forced removal and incarceration of Japanese Americans, the War Relocation Authority, and others; publications, photographs, and ephemera from the Topaz Relocation Center, where Goodman taught high school; War Relocation Authority records and publications; and newspaper clippings, pamphlets, and reports about forced removal and incarceration created by various government, religious, and civic organizations, in California and nationwide
