Valorization of Edible Mushroom and Fish Waste for the production of Vitamin D
No full textThis study highlights the importance of looking into novel approaches to optimize the use
of mushroom and fish waste as a beneficial source of vitamin D, which can help address
nutritional deficiencies and promote sustainable practices in food production by utilizing
the potential of fish waste. This study contributes to the larger objective of efficiently
producing vital nutrients like vitamin D from food by-products, such as edible mushroom
and fish waste. Furthermore, it also increases the availability of vitamin D, including
mushroom and fish waste into our diets becomes a viable option for both environmental
sustainability and human health. The main objectives of this thesis work are:
1. Optimize the parameters of the ultrasonic extraction method to obtain the optimal
conditions for extracting ergosterol. This objective focuses on the optimization of
the ultrasonic extraction of vitamin D to determine the optimal parameters for the
extraction of ergosterol from mushrooms. Ergosterol is a precursor of vitamin D2
and increases the vitamin D content after exposure to UV light. In this experiment, various parameters such as ultrasonication time, temperature, solvent concentration
and frequency were optimized to greatly increase the ergosterol yield, which will
help to convert it into large amounts of vitamin D in the future. 2. Refine the conversion process of ergosterol to vitamin D within mushrooms when
subjected to UV light. The objective was to optimize the UV parameters so as to
increase the conversion of ergosterol to vitamin D2 in mushrooms. In this study, the optimal UV wavelength, irradiation time and intensity were optimized to
maximize the production of vitamin D2. The parameters optimized in this study
significantly enhanced vitamin D2 in mushrooms, thereby contributing to dietary
supplements and fortified foods. 3. Conversion of 7-dehydrocholesterol to vitamin D3 from fish waste: The objective
was to optimize the UV irradiation conditions so as to increase the conversion of
7-dehydrocholesterol (7-DHC), a precursor of vitamin D3, and vitamin D
production from fish waste. The aim of the present study was to optimize UV
parameters for the conversion of 7-DHC to vitamin D3, which increased vitamin D
content, and to assess the potential of fish waste as a valuable source of vitamin D
production. 4. The abroad research is a rapid and non-destructive determination of the fat content
of potato chips by hyperspectral imaging analysis. The study was conducted at
Virginia Tech, USA. The use of hyperspectral imaging analysis to determine fat
content in potato chips. The aim was to develop a technique that would allow a
rapid and accurate assessment of fat content and its subsequent application to the
assessment of vitamin D content. This research contributes to the field of rapid
analysis of food composition. These objectives are treated in this manuscript according to the following section scheme:
A. A general introduction through literature review on vitamin D
B. The presentation of the experimental work divided in chapters related to the
published/prepared research papers. In this section 5 chapters are present:
i. Optimization of the parameters for ergosterol extraction using ultrasonic
extraction method
ii. Optimization of the parameters for the conversion of ergosterol to vitamin D2 in
mushrooms under UV light. iii. Evaluation of nutritional values of Oyster mushroom (Pleurotus ostreatus) wastes
(caps, stipes, and bulbs) iv. The study of the conversion of 7-dehydrocholesterol to vitamin D3 in fish, followed by the determination of vitamin D3 content using HPLC-DAD. v. A rapid and non-destructive determination of the fat content of potato chips using
hyperspectral imaging analysis methods. C. The overall conclusions of this thesis work

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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

Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
