OBSTETRIC shock is one of the most serious of the accidents associated with childbirth. Puerperal sepsis is the only condition responsible for a larger proportion of maternal deaths. Out of 141 consecutive deaths occurring in the Belfast Maternity Hospital, and the Royal Maternity Hospital, Belfast, during the ten years, 1927-36, twenty-three, i.e., 16.3 per cent., were due to obstetric shock. ...

Nowadays, the importance of the vehicles and its dramatic effects on human life is no secret. The use of trailers with multiple axels for transporting bulky and heavy equipment is essential. Increase in trailers axles which results increment of wheels, needs considerations in order to increase in transporting speed, maneuverability, safety, better control and path following accurately.  Therefo...

Web-based distance learning has evolved to a point where those operating or contemplating such programs can profit from the experience of its early adopters and practitioners. This study uses as its basis the experiences of institutions—community colleges, large research universities, state/ regional systems, and elite private institutions—that have actively pursued Webbased distance-learning i...

car-following models, as the most popular microscopic traffic flow modeling, is increasingly being used by transportation experts to evaluate new intelligent transportation system (its) applications. a number of factors including individual differences of age, gender, and risk-taking behavior, have been found to influence car-following behavior. this paper presents a novel idea to calculate the...

Let Fq denote a finite field with q elements and let V = (Fq)m,n be the Fq-vector space of matrices over Fq of type (m,n). On V we define the so-called rank metric distance by d(A,B) = rank(A−B) for A,B ∈ V . Clearly, the distance d is a translation invariant metric on V . A subset C ⊆ V endowed with the metric d is called a rank metric code with minimum distance d(C) = min {d(A,B) | A 6= B ∈ V...

Distance education in the present Russian Federation and former Soviet Union has a long tradition that prevails to this day. The majority of students in Russia are enrolled in distance learning programs. The numbers indicate the existence of a well-established system for distance education, of which little is known in Western literature. A review of distance education research in the Anglo-Amer...

Perceptual variables such as perceived distance contain information about future actions. Often our goals involve the integration of another’s goals, such as lifting heavy objects together. The purpose of this study was to investigate how another’s actions might influence one’s own goal-oriented perceptions, specifically, verbal distance estimates. Using a within-subject paradigm, we replicated...
