Probabilistic Model for M2M in IoT networking and communication
Springer Science + Business Media 2016 Journal of Telecommunication systems Vol.62 No.1
<P>In this paper, a probabilistic model for M2M in IoT networking and communication mode is presented with mobile and dynamic machines in the network. The scenario is considered stochastic and thus probability distribution describing the times between successive machines entry in to the network is predicted by means of a graph. A graph based model is also presented to find the shortest path and lowest cost between machines. For large scale network, parallel M2M establish connection inside a network and are partitioned and dynamically refigured such as IoT. Simulation were performed for multiple M2M array for different state, timing and power consumption along with the scheduling scheme are considered.</P>
Comparison of different Brazilian citrus by-products as source of natural antioxidants
Paula de Paula Menezes Barbosa,Amanda Roggia Ruviaro,Gabriela Alves Macedo 한국식품과학회 2018 Food Science and Biotechnology Vol.27 No.5
Significant amounts of citrus by-products remain after juice processing, which is then used to obtain pectin. The pectin industry then generates a new waste. No study has characterized this residue or suggested applications for it. The main goal of this study was to compare citrus industrial by-products that remain after juice (CJB) and pectin (CPB) extraction, aiming to obtain bioactive compounds. The residues were evaluated for their chemical composition, antioxidant capacity, and polyphenols content. CJB had 2-fold higher total phenols than CPB. Moreover, CJB exhibited higher antioxidant capacity than CPB. Nine polyphenols were detected; hesperidin was the main compound on both residues. CPB had higher content of polyphenols than CJB, which can be attributed to the industry procedure of pectin extraction. Thus, this study provides support for the reuse of CPB to obtain nutraceutical compounds, converting waste into added-value products.

Microbial oils enriched in essential polyunsaturatedfatty acids can be used as nutritionalcomplements. In order to improve the lipid yields and lipidprofiles of 2 Yarrowia lipolytica strains, the effects ofmedium components and culture conditions were investigatedusing shake flasks. Under optimized conditions (cultivationfor 3 days at 25ºC and 150 rpm, using peptone as anitrogen source and glucose as a carbon source), thebiomass, lipid yield, and lipid content reached 6.75 g/L,3.48 g/L, and 51.55% for Y. lipolytica QU22, and 6.85 g/L,3.52 g/L, and 51.38% for Y. lipolytica QU137, respectively. Using a shaking speed of 150 rpm, unsaturated fatty acidsconstituted 87.96% (QU22) and 87.08% (QU137) of thetotal lipids produced by these strains, with 9.52 and 7.86%of alpha-linolenic acid, respectively. The strains are suitablecandidates for fermentation processes involving essentialpolyunsaturated fatty acid (PUFA) production.
Fostering Learners' Intercultural Competence with CALL
Paula Garrett-Rucks 서울대학교 외국어교육연구소 2017 외국어교육연구 Vol.20 No.-
There is increasing pressure on world language educators to expand the cultural instruction in their curriculum and to advocate for their language programs as a means to prepare learners with 21st century skills (The Four Cs: Creativity, Communication, Collaboration, and Critical thinking). In similar vein, ACTFL’s Global Competence Position Statement (2014) further described the need for language instructors to foster learners’ interactional abilities and behaviors to perform effectively and appropriately when interacting with others who are linguistically and culturally different from self. Yet many language educators are confused about best-teaching practices during this transition time from methods that focus primarily on students’ ability to use the language to communicate, to a time where it is increasingly emphasized that students should access content information through the language for meaningful cultural reflection. This paper demystifies some confusion about fostering learners’ intercultural competence in instructed language learning and concludes with a variety of tools and techniques to integrate computer-assisted language learning (CALL) and meaningful cultural inquiry at beginning levels of instruction.
