in this paper, we develop a freight transportation model for railway network considering hazmat transportation issue. in the transportation system considered, different customers can request for carrying hazmat and non- hazmat boxes. it is assumed that the sequence of the trains in the network is known. the objective is assigning the non-hazmat boxes and hazmat boxes to wagons of the trains so ...

pondents are invited to offer any " clinical remarks" they may have to make bearing on the subject. I therefore venture to hope that the few following remarks may prove acceptable to your readers. The facts of the case as related are as follows :? Mrs. S. a young woman of 29 years of age, of a fair complexion and previous good health, meets with a fright on the 10th June while driving in her gh...

In 1990, M. Main and J. Solomon introduced the procedures for coding a new "disorganized" infant attachment classification for the Ainsworth Strange Situation procedure (M.D.S. Ainsworth, M. Blehar, E. Waters, & S. Wall, 1978). This classification has received a high degree of interest, both from researchers and from child welfare and clinical practitioners. Disorganized attachment has primaril...

Air-breathing, diving ectotherms are a crucial component of the biodiversity and functioning of aquatic ecosystems, but these organisms may be particularly vulnerable to the effects of climate change on submergence times. Ectothermic dive capacity is thermally sensitive, with dive durations significantly reduced by acute increases in water temperature; it is unclear whether diving performance c...

In 1990 we advanced the hypothesis that frightened and frightening (FR) parental behavior would prove to be linked to both unresolved (U) adult attachment status as identified in the Adult Attachment Interview and to infant disorganized/disoriented (D) attachment as assessed in the Ainsworth Strange Situation. Here, we present a coding system for identifying and scoring the intensity of the thr...
