The paper presents the suitability of flyash-limephosphogypsum composite for its use in road pavements. The content of lime and phosphogypsum was varied from 2 to 10% and 0.5 to 4% respectively in flyash. The specimen prepared was cured for 7, 28, 56 and 90 days with burlap method of curing. Compaction tests were conducted on different flyash-lime-phosphogypsum composite and these results were ...

background: attenuation coefficient (μ) plays an important role in calculations of treatment planning systems, as well as determination of dose distributions in external beam therapy, dosimetry, protection, phantom materials and industry. so, its exact measurement or calculation is very important. the aim of this study was to evaluate the μ in different points in the water phantom analytically ...

the concepts of free modules, projective modules, injective modules and the likeform an important area in module theory. the notion of free fuzzy modules was introducedby muganda as an extension of free modules in the fuzzy context. zahedi and ameriintroduced the concept of projective and injective l-modules. in this paper we give analternate definition for projective l-modules. we prove that e...

First we show that the cosets of a fuzzy ideal μ in a BCK-algebraX form another BCK-algebra  X/μ (called the fuzzy quotient BCK-algebra of X by μ). Also we show thatX/μ is a fuzzy partition of X and we prove several some isomorphism theorems. Moreover we prove that if the associated fuzzy similarity relation of a fuzzy partition P of a commutative BCK-algebra iscompatible, then P is a fuzzy quo...

In this paper, we used tetranuclear copper (II) Schiff base complexes, [Cu4 (μ-sal2hn) (μ-N3)2(N3)2] (1) and [Cu4 (μ-salophen) (μ1, 1-N3)2(N3)2] (2), as new precursor in solid-state thermal decomposition for the synthesis of CuO ...

objective: the aim of this study was to compare the microtensile bond strengths (μ tbs) of three core materials with one lithium disilicate reinforced ceramic using two resin cements. methods: three core materials (nulite f® (biodental technologies), filtek z250® (3m-espe), prettau-anterior® (zirkonzhan, germany)) were prepared as blocks (10×10×4 mm3) according to the manufacturer’s instruction...

This paper proposes new techniques for efficiently parallelizing sliding window processing over data streams on a shared-nothing cluster of commodity hardware. Data streams are first partitioned on the fly via a continuous split stage that takes the query semantics into account in a way that respects the natural chunking (windowing) of the stream by the query. The split does not scale well enou...

A family of sets is intersecting if every pair its intersect. star a with some element (a center) in each sets. The classical result Erdős, Ko, and Rado (1961) states that r-subsets [n] r≤n/2 has size at most star. Let G be graph, α(G) independence number, μ(G) the smallest maximal independent set G. We say r-EKR if, among all maximum-sized families vertices G, there In 2005 Holroyd Talbot conj...

Head-splitting fractures occur as a result of violent compression of the head against the glenoid; the head splits and the tuberosities may remain attached to the fragments or split and separate. Isolated humeral head-splitting fractures are rare injuries. Favorable results with osteosynthesis can be difficult to achieve because of the very proximal location of the head fracture and associated ...
