Granular materials are of substantial importance in many industrial and natural processes, yet their complex behaviours, ranging from mechanical properties of static packing to their dynamics, rheology and instabilities, are still poorly understood. Here we focus on the dynamics of compaction and its 'jamming' phenomena, outlining recent statistical mechanics approaches to describe it and their...

Earth reinforcing techniques have become useful and economical to solve problems related to difficult grounds and provide satisfactory foundation performance. In this context, this paper uses radial basis function neural network (RBFNN) for predicting the bearing pressure of strip footing on reinforced granular bed overlying weak soil. The inputs for the neural network models included plate wid...

he fundamental arrangement of granular behavior is important to know about the soil stability and influence the design of structural foundations. The structural stability is particularly useful in earthquake events. Therefore, to work on measuring the arrangement and orientation of an assemblage of granular particle is essential. In this paper, we evaluate the porosity of the given sand images ...

C. elegans is a round worm that lives in wet soil and moves by undulating its body in a sinusoidal wave. We perform experiments on wild-type C. elegans swimming in a granular medium composed of 98 m glass particles and aqueous fluid. Figure 1 shows that a worm swims faster in a granular medium V 0.46 mm /s than in a fluid without particles V 0.37 mm /s . C. elegans in a granular medium undulate...

Expansive soils are often encountered in many parts of the world, especially in arid and semi-arid fields. Such kind of soils, generally including active clay minerals in low water content, enlarge in volume by absorbing the water through the surface and cause a great harm to the light structures such as channel coating, roads and airports. The expansive soils were encountered on the path of Ap...

Aldicarb residues in soil, cottonseed, and cotton lint following an in-furrow soil application of 15 lb/acre of a 10% granular formulation of the insecticide on the Texas High Plains were investigated by a gas chromatographic-flame photometric detection procedure. Aldicarb residues (as the sulfone) as high as 1.65 ppm (average of three laboratoyies) were detected in soil from dryland fields 3 (...

The effect of nematode population density at the time of application and formulations of in vitro-produced Pasteuria spp. endospores on the final population density of Belonolaimus longicaudatus was studied in an 84-d-long pot bioassay. The experiment utilized a factorial design consisting of 30 or 300 B. longicaudatus /100 cm of sandy soil and three formulations of in vitro-produced Pasteuria ...
