No full textChemical characterization of camelina seed oil:
No full textCamelina sativa (L).Crantz also known as false flax, Dutch flax is an ancient oil seed crop that belongs to the Brassicaceae family. Camelina oil pressed from the seeds of this crop has a unique aroma.
Eighteen camelina oil samples were analyzed for fatty acid composition (13 unrefined, 2 deodorized and 3 refined samples). Eight of these samples were analyzed for unsaponifiables content, free fatty acids and volatiles and semi-volatile compounds. Seven camelina seed samples were analyzed for volatile and semi-volatile compounds as well to determine the suitability of these products in animal feed formulations.
Fatty acid composition was obtained by the trans-esterification of the triacylglycerols in the oil to their methyl esters and 21 different fatty acids with chain length from C-14 to C-24 were identified. The major fatty acids were α-linolenic, linoleic, oleic, eicosenoic and palmitic acid and three fatty acids, namely tricosanoic, pentadecanoic and heptadecanoic are being first reported here.
The unsaponifiables fraction in camelina oil samples ranged between 0.45-0.8% and 21 compounds were identified. The major compounds identified were β-sitosterol, campesterol, cholesterol, phytol, squalene and brassicasterol which accounted for 80-90% of the unsaponifiable content in camelina oil.
A total of 168 and 306 volatile and semi-volatile compounds were identified in the headspace of camelina seeds and oil respectively. Homologous series of lipid oxidation derived compounds like aldehydes, ketones, alcohols, furans and hydrocarbons dominate the aroma and favor profile of the oil and seeds. Sulfur compounds (methyl mercaptan, dimethyl sulfide, dimethyl disulfide and dimethyl trisulfide), naturally occurring 3-alkyl-2-methoxy pyrazines, terpenes, short chain free fatty acids and maillard reaction products were also identified in camelina seeds. The presence of 2-sec-butyl-3-methoxy pyrazine, aldehydes and alcohols (with green notes) and sulfur compounds like 2, 4, 5-trithiahexane and 1-butene-4-isothiocyanato in some camelina oils, may be responsible for the unique aroma of this oil.
The information from this study may potentially be used by camelina oil producers as supporting data for the chemical characteristics of the oil produced in Montana, USA. Camelina oil can serve as a good vegetable source of α-linolenic acid provided it gets the much awaited GRAS certification.M.S.Includes bibliographical references (p. 165-170)by Anusha Sampat
From childhood to nationhood: memory, media and malevolence
No full textThis talk explicates the entangled relationship between childhood and nationhood in the Indian context through the analysis of two key events in modern Indian history. The current right-wing nationalist discourse in India espouses an ethnonationalist identity that relies on a unitary logic of race, religion, land, and language. This logic is founded upon Savarkar’s slogan of “Hindi, Hindu, Hindustan” that valorizes not only the Hindu religion but also the Aryan race, the Hindi language, and the land beyond the river Indus. Children and young people are perceived to be the crucible of this Hindu nation that (supposedly) rightfully belongs to the Hindu Brahmanical Hindi-speaking Aryan male. This presentation aims to show how history, narrativity and performance have been deployed to center the figure of the child as well as real children (and youth) as critical players of the Neo-Hindutva discourse. Through a combination of field evidence, secondary literature and media sources, this poster shows how stories and memories are instrumental in the production and propagation of nationalist discourses to children and young people. The talk expounds different tactics such as distorting history, maneuvering memory and rewriting myths that are deployed within the private spaces of homes, the public spaces of schools and neighborhoods and mediatized spaces of movies, through which children imbibe as well as disseminate the idea of India as a Hindu nation.This work was accepted to the annual Graduate Research and Creative Works Symposium while the author was a graduate student at Rutgers University-Camden
ArmSleeve: A patient monitoring system to support occupational therapists in stroke rehabilitation
No full textThis paper describes the design of "ArmSleeve", a patient monitoring system to support occupational therapists in their upper limb rehabilitation work with stroke patients. Occupational therapists can provide rehabilitation in clinics, but they have limited insights into how much their patients use their affected arm and hand in daily life, which is critical for effective recovery to occur. Our work addresses this problem through three interrelated studies: (1) interviews with therapists to examine their current rehabilitation practices; (2) the design of the "ArmSleeve Sensor" to monitor a patient's upper limb movement; and (3) the design and evaluation of the "ArmSleeve Dashboard" to visualize this information for therapists. The findings show the importance of collecting objective data to assess exercise and activities outside therapy, but also a lack of contextual information to interpret this data. We discuss considerations for how to address this issue through patient engagement as well as considerations for designing wearable sensor technology that is usable in everyday life
