We introduce the notion of weak subnormality, which generalizes subnormality in the sense that for the extension b T ∈ L(K) of T ∈ L(H) we only require that b T ∗ b Tf = b T b T ∗f hold for f ∈ H; in this case we call b T a partially normal extension of T . After establishing some basic results about weak subnormality (including those dealing with the notion of minimal partially normal extensio...

Milestones like the centennial of the Cooperative Extension system are significant in any organization. Milestones measure progress along a path, but can also give reassurances that travelers are on the right track. As Extension moves into the next century, we must continuously ask ourselves if it is focused and on the right path. What are some guiding principles that we need to follow? What ar...

A multiple-valued function f : X → QQ(Y ) is essentially a rule assigning Q unordered and non necessarily distinct elements of Y to each element of X. We study the Lipschitz extension problem in this context by using two general Lipschitz extension theorems recently proved by U. Lang and T. Schlichenmaier. We prove that the pair ` X,QQ(Y ) ́ has the Lipschitz extension property if Y is a Banach ...

We present two prudent semantics within Dung’s theory of argumentation. They are based on two new notions of extension, referred to as p-extension and c-extension. Two arguments cannot belong to the same p-extension whenever one of them attacks indirectly the other one. Two arguments cannot belong to the same c-extension whenever one of them indirectly attacks a third argument while the other o...

in this study, damar batu (db) − a novel biomaterial− is evaluated for its potential application in pharmaceutical coating. db is a whitish to yellowish resin, characterized initially in terms of solubility, acid value, molecular weight (mw), polydispersity index (mw/mn) and glass transition temperature (tg). neat plasticized films of db are investigated for mechanical, water vapor transmission...

conclusions this case report supports the beneficial role of erythropoietin in function, maintenance, and recovery of neurons. erythropoietin is a double-edge sword, as long-term erythropoietin therapy has some complications, like thromboembolism and stroke. recent studies suggested that erythropoietin should be given as single high dose to exert a rapid neuro-protective effect with minimal hem...

background: gts, ptsm and atsm are bis-thiosemicarbazone ligands used in the preparation of copper radiopharmaceuticals. chemical structure of these materials indicates that they should have radio-protective effects. objective: to study the radio-protective effects of gts, ptsm and atsm. methods: this study has focused on radio-protective effects of these compounds at different doses (20, 40 an...

the present study aimed to determine awareness of tehran residents of seven warning signs of cancer, and application of protective measures against cancer. 2500 residents of tehran were selected through systematic cluster random sampling. data collection tool consisted of a questionnaire, comprising 3 sections of demographic details, awareness of warning signs of cancer, and application of prot...

occupational exposure to cytotoxic drugs is a global concern. we conducted this cross-sectional study in 2012 to describe the adverse effects experienced by nurses working in one of chemotherapy facilities affiliated to shiraz university of medical sciences, shiraz, southern iran, and their proper use of personal protective equipment and educational programs. the frequency of side effects repor...

In this paper a method to extend discrete uninorms and nullnorms on the finite chain L = {0, . . . , n}, to uninorms and nullnorms defined on the set of discrete fuzzy numbers whose support is a set of consecutive natural numbers contained in L is presented. Some basic properties of discrete uninorms and nullnorms are preserved by this extension method and the structure of these kinds of aggreg...
