Copper substitution together with nano-structuring are applied the aim to increase bactericidal performances of rocksalt-type MgO oxide. The partial magnesium ions Cu2+ has been successfully achieved in both micrometer- and nanometer-sized particles up 20 mol% increments 5 mol%. Microstructural analyses using Integral Breadth method revealed that thermal decomposition single source precursor Mg...

This paper proposes a new fuzzy assessing procedure with application in management decision making. The proposed fuzzy approach build the membership functions for system characteristics of a standby repairable system. This method is used to extract a family of conventional crisp intervals from the fuzzy repairable system for the desired system characteristics. This can be determined with a set ...

We consider the locally repairable codes (LRC), aiming at sequential recovering multiple erasures. We define the (n, k, r, t)SLRC (Sequential Locally Repairable Codes) as an [n, k] linear code where any t(≤ t) erasures can be sequentially recovered, each one by r (2 ≤ r < k) other code symbols. Sequential recovering means that the erased symbols are recovered one by one, and an already recovere...

The multistage theory of carcinogenesis specifies that cells progress to cancer through a series of discrete, irreversible genetic alterations, but data on radiation-induced cancer incidence in rat skin suggests that an intermediate repairable alteration may occur. Data are presented on cancer induction in rat skin exposed to the following radiations: 1. an electron beam (LET = 0.34 kev/mu), 2....

Phased mission analysis is carried out to predict the reliability of systems which undergo a series of phases, each with differing requirements for success, with the mission objective being achieved only on the successful completion of all phases. Many systems from a range of industries experience such missions. The methods used for phased mission analysis are dependent upon the repairability o...

PURPOSE OF REVIEW To highlight the relevance of preoperative differentiation of degenerative mitral valve disease based on etiology (predominantly Barlow's Disease or fibroelastic deficiency) and severity of lesions with an emphasis on how such differentiation by the cardiologist can result in increased rate of mitral valve repair. RECENT FINDINGS In the hands of reference mitral valve-repair...

Minimum storage regenerating (MSR) codes form a special class of maximum distance separable (MDS) codes by providing mechanisms for exact regeneration of a single code block in their codewords by downloading the minimum amount of information from the remaining code blocks. As a result, the MSR codes find application to distributed storage systems to enable node repairs with the optimal repair b...

La maladie de Gaucher de type 1 (MG1) est une maladie multisystémique rare due à un déficit génétique en bêtaglucocérébrosidase lysosomale. Ses signes cliniques sont très polymorphes: splénomégalie (95%), hépatomégalie (80%), cytopénies (thrombopénie, anémie, neutropénie)... L'atteinte ostéoarticulaire est une complication majeure qui se voit dans 70 à 100% des cas selon les séries. Les anomali...
