The main objective of this study is to evaluate the workability of fresh portland cement concrete while it is still in the mixing truck by determining fundamental rheological parameters (plastic viscosity and yield stress). Nine concrete mixtures with different values of yield stress and plastic viscosity were tested in a concrete truck. The measurements made with the truck were based on the ty...

Railway lines typically use traditional sloping embankments as the principal means of track support. However, Geosynthetically Reinforced Soil (GRS) systems have gained popularity alternatives to conventional embankments, particularly for high-speed in Japan. This system requires less ground stabilization/improvement and land take than due its smaller base area. research investigates immediate ...

As prestressed concrete sleepers are continuously exposed to various environmental and loading conditions, it is increasingly crucial analyse their current future serviceability performance. In practice, the main cause of cracking in usually induced by impact loads. The most heavily influenced sections midspan rail-seat area sleepers. This paper investigates effects time-dependent strength degr...

Pipes (2003) has proposed a checklist for law enforcement to use in identifying possible members of sleeper cells. The purpose of this research was to evaluate Pipes’ checklist through the judgment of Muslim “insiders.” Thirty-three Muslim insiders responded to Pipes’ checklist by indicating the degree of concern that they believed each item should trigger about a possible sleeper. The sample o...

The "sleeper effect" has been defined as a delayed increase in the persuasive impact of a communication from a source low in credibility. This effect failed to appear in the present series of seven replications (total N = 656) of a sleeper effect experiment. However, the effectiveness of communications attributed to a source high in credibility did significantly decrease with passage of time wh...

—We collected and compiled length and weight information from four countries and one commonwealth to develop standard weight (W s ) equations for three amphidromous fish species native to the Caribbean and Gulf of Mexico regions: mountain mullet Agonostomus monticola (N 1⁄4 9,768 individuals, 52 populations), river goby Awaous banana (N 1⁄4 1,847 individuals, 62 populations), and bigmouth sleep...

Objectives: Various stretching techniques have been proposed to prevent or improve Glenohumeral Internal Rotation Deficit (GIRD) and Posterior Shoulder Tightness (PST). Common stretching techniques include modified sleeper stretch and cross-body stretch. The current evidence is unclear which stretching technique is more effective. This study aimed to examine immediate effects of modified sleepe...

Nowadays, railway transport plays a very important role in the system period of positive growth commerce, economy and industry. In accordance with other modes transport, is most stable mode for transporting, safety, capability carrying, social economic benefits. Sleepers have major roles complex distributed load from rails when train goes through to ballast. This study discussed pre-stressed co...
