This study introduced a method based on magnetic field assisted finishing mechanism for micromachining the inner surfaces of Aluminum tubes. In this approach, using the alternating magnetic field of an AC electromotor, abrasive particles were formed as Magnetic Rods (Magnetic Clusters) and surface micromachining was carried out by the dynamic particular pattern made by an alternating magnetic f...

The detrimental drought effects could be listed as the loss in dry weight and silicon is known to enhance crop tolerance to drought by increasing seedling growth and hydraulic conductivity. To investigate the effects of silicon priming (0, 1 and 2 mM as sodium silicate), on seedling growth and root anatomy of three barley cultivars (Khatam, Rihane, and Nimrooz) a laboratory experiment was condu...

Symmetric graphs, such as the n-dimensional Boolean hypercube Qn, and the cube-connected cycles, have been widely used as processor or communication interconnection networks. For designing, analyzing and improving such networks, Akers and Krishnamurthy proposed a formal grouptheoretic model in [1]. Based on the model, the n-dimensional bubble-sort graph is proposed as one of those classes of ne...

The token ring topology is required in token passing approach used in distributed operating systems. Fault tolerance is also required in the designs of distributed systems. Note that 1-fault-tolerant design for token rings is equivalent to design of 1-Hamiltonian graphs. This paper introduces a new family of graphs called Christmas tree, denoted by CT(s). The graph CT(s) is a 3-regular, planar,...

Swyer-James-Macleod syndrome (SJMS) is a rare constrictive bronchiolitis with air-flow obstruction and a decreased number and diameter of ipsilateral peripheral pulmonary vessels. This syndrome is characterized by unilateral hyperlucency on chest radiography. Computed tomography provides useful additional information. The diagnosis is usually made in childhood but sometimes occurs in adulthood....

The paper deals with mesh-connected massively-parallel systems affected by failures. The complexity of a local diagnostic procedure, based on new deenitions of the local k-diagnosability and the r-fault-tolerance, is analysed. It depends on distances between individual fault clusters and on fault cluster diameters. In particular cases the minimum distance between fault clusters can be enlarged ...

This paper introduces a new fault tolerant interconnection topology called the Extended crossed cube (ECC). The proposed topology is hierarchical, expansive and recursive in nature. It has reduced diameter, average distance and constant degree of nodes. The paper illustrates various other properties of the proposed system, such as fault-tolerance, reliability, message traffic density, cost, cos...

BACKGROUND Baked egg is tolerated by a majority of egg-allergic children. OBJECTIVE To characterize immunologic changes associated with ingestion of baked egg and evaluate the role that baked egg diets play in the development of tolerance to regular egg. METHODS Egg-allergic subjects who tolerated baked egg challenge incorporated baked egg into their diet. Immunologic parameters were measur...
