Maintenance is what is done in machinery to prevent failure or breakdown. In ancient times no proper planning was carried out to do maintenance with the idea behind being simple machines and easy to control. As time progresses people started to find out that it was necessary to safeguard equipment to reduce costs for continuous growth. Maintenance is best divided its phases by world war two due...

Introduction We consider the graded algebra (the generators have weight one)

We give several equivalent combinatorial descriptions of the space of states for the box-ball systems, and connect certain partition functions for these models with the q-weight multiplicities of the tensor product of the fundamental representations of the Lie algebra gl(n). As an application, we give an elementary proof of the special case t = 1 of the Haglund–Haiman–Loehr formula. Also, we pr...

Museums and galleries in the UK increasingly engage with educational and social concerns; this article refers to research to evaluate two such initiatives. Evaluation of the Museum and Gallery Education Programme Phase 2, funded by the Department for Education and Skills, ends in August 2004. The research partnership to evaluate the ‘En-vision’ pilot action research programme, established by En...

We are told that an object is hidden in one of m(m < ») boxes and we are given prior probabilities p. that the object is In the i box. A search of box i costs c. and finds the object with probability a. if the object is in the box. Also, we suppose that a reward R. is earned if the object Is found in the i box. A strategy is any rule for determining when to search and if so which box. The major...

many recent studies have shown that glycosylation patterns of agaricus bisporus are similar to those of mammalians, so that this organism is a good candidate for the expression of glycosylated pharmaceutical protein. to achieve constant interested gene expression in all cells of the organism, proper promoter isolation is necessary. to isolate this promoter, pcr with specific primers was perform...
