Studying Non-coaxiality in Non-lane-based Car-following Behavior
Authors: Ramezani Khansari Ehsan , Tabibi Masoud , Moghadas Nejad Fereidoon 
Published: December 2018

In this paper, in order to study non-lane-based car-following, the non-coaxiality concept is defined, where there is a significant lateral difference between the leader and follower vehicle. Two main reasons for non-coaxiality were addressed by drivers in the interview: providing more visible distances beyond leader vehicle and increasing the possibility of escaping in sudden brakes to avoid rear-end collision. Results showed that non-lane-based behavior was due to the effect of the existence of other cars in the traffic flow. By reducing speed or increasing density, vehicles more affect each other. But this trend will continue up until vehicles fill the free spaces. In other words, vehicles make others stick to the leader’s path in high-density flow. Studying the relationship between lateral distance and time headway demonstrated that time headway threshold for initiation of car-following behavior in Iranian drivers can be approximately 2 seconds. In this study, Overtaking was defined as a part or continuation of the non-lane-based driving behavior. For overtaking on the left, steering angle, the final lateral distance and the lateral speed difference between the follower and leader were 33%, 28% and 15% less than overtaking on the right.
Hedges and boosters in plenary speakers’ conference abstracts vs. novice researchers’ conference abstracts
Authors: EKOÇ Arzu 
Published: December 2018

Conference abstracts are essential components of
academic studies as potential participants decide to attend the session based
on what they get from the content of the abstracts. However, conference
abstract writing has received relatively less attention compared to research
article and thesis abstracts. Representing and summarizing the whole
presentation in a limited space requires competence.&nbsp; In writing a conference abstract, one should
take an academic speaking position by claiming significance, credibility and
novelty. In academic conferences, there are two or three invited plenary
speakers who are very experienced, full -fledged academics and in the
concurrent sessions, many novice researchers who are often at the very
beginning of their academic studies. Novice researchers’ abstracts are being
assessed by scientific committees while plenary speakers’ abstracts are exempt
from this review process. Academics, whether they are experienced or novice,
make use of lexical hedging&nbsp; and boosting
strategies that show their degree of confidence in the truth of their
statements but also reveal their opinions and attitudes to the reader. In this
small scale study, 10 plenary speakers’ conference abstracts and 10 novice
researchers’ conference abstracts are chosen randomly from different
conferences and the aim is to analyze if there is any variation between plenary
speakers’ conference abstracts and novice researchers’ conference abstracts in
the use of hedging and boosting strategies with regard to frequency counts on
lexical bases.&nbsp;

Ethnobotanical study of plants used by Thami community in Ilam District, eastern Nepal
Authors: Bhattarai Krishna Ram 
Published: December 2018

An ethnobotanical survey was carried out on the utilization of plants by Thami communities in Gorkhe, Jogmai and Nayabazar areas of Ilam by interviewing traditional herbalists and different age groups of men and women in June 2016. A total of 30 plants belonging to 24 families and 29 genera have been documented. These plants were used for food, fodder, firewood, medicine and in rituals. The documented medicinal plants were used to treat various human ailments of 12 categories; with the highest number of species being used for gastro-intestinal disorders (15 spp.) followed by ENT problems (14 spp.). Most of the medicines were prepared from underground parts in the form of paste and used orally. Informant Consensus Factor (Fic) ranges from 0.6 to 0.9 with an average of 0.82. Dermatological disorders have the highest Fic (0.90) and other categories have the lowest (0.6). Aconitum palmatum, Begonia picta, Bergenia ciliata, Astilbe rivularis, Swertia chirayita, Drymaria cordata and Remusatia pumila have the highest fidelity level (100% each) and Galium asperifolium has the lowest FL (16%). According to the use value, Swertia chirayita (UV=2.83) was the most important with uses against 6 ailments and Hypericum cordifolium has the least (UV=0.08), used in only one ailment. A variation in ethnobotanical knowledge was found according to age, gender and occupation in this community.
Effect of stress-induced magnetization on crack monitoring by self magnetic flux leakage method
Authors: van der Horst Menno Patrick , van Kreveld Sylvia Lyanne , Kaminski Miroslaw Lech 
Published: December 2018

Wireless crack monitoring on ships and offshore structures based on Self Magnetic Flux Leakage (SMFL) measurements is a promising method to guarantee the structural integrity in a more effective way, leading to reduced operational costs and increased safety. For accurate crack sizing, the SMFL measurements must be interpreted correctly, also during cyclic loading. Not much research has been done that focus on the effect of high cyclic stresses on the magnetization of ferromagnetic steels in weak magnetic fields. The aim of the research presented in this paper is to investigate the effect of stress-induced magnetization on the SMFL in the stress concentration zone of a structural steel plate, and its implications for crack monitoring by the SMFL method. By means of an experiment, measured stress magnetization curves were obtained in a grid of points around an elliptical hole in a steel plate that was cyclically loaded up to the yield stress. The results show that the stress-induced magnetization causes a maximum variation of the measured signal of 25 μT, which is fully reversible. It is concluded that, depending on the application, this stress-induced variation may need to be taken into account for the interpretation of the measured signals by a crack monitoring system using the SMFL method.
