Proof. In [4] it was shown that ps<pt for any two positive integers 5 and / for which s<t. Hence the lemma is true if 7 and 5 are each integers. Since, for 5 finite, ps<p(s + l) ^uo)^p(oo*+oj) and ps<p(s + l) ^pco*^p(co*+o}), it follows that the lemma is true if one of the elements 7 or 5 is finite, and the other is not. Suppose that pu and pu* are demonstrated to be incomparable order types.2 ...

In this study, nanoscale zero-valent copper (nZVC) as catalyst activated persulfate (PS) was used for the degradation of p-chlorophenol (p-CP) under ultrasonic (US) irradiation in aqueous solution. The effect of different operational parameters such as solution pH (3.5-10.5), PS concentration (1-7.5 mm/L), nZVC dosage (5-35 mg/L) and initial p-CP concentration (10-100 mg/L) were evaluated at di...

Professional standards are a significant issue for professions such as IT and Project Management, where certification and licensure are either necessary to practice or to demonstrate individual competence and capability. In many professions there is no basis for international reciprocity of professional standards. This paper documents the development of a standard for global reciprocity between...

Highly monodisperse polystyrene/poly(N-isopropylmethacrylamide) (PS-PNIPMAM) core-shell composite microgels were synthesized and further nanoengineered in either ellipsoidal, faceted or bowl-shaped particles. Beside their anisotropy in shape, the microgel design enables an exquisite control of the particle conformation, size and interactions from swollen and hydrophilic to collapsed and hydroph...

In this paper, we introduce the notion of fuzzy dot PS-subalgebras in PSalgebras and establish its various properties.

Slow positrons implanted into a porous silica film may efficiently form positronium (Ps) atoms that diffuse through a network of interconnected pores. At high Ps densities, the long lifetime of ortho-positronium atoms is reduced due to Ps-Ps spin dependent interactions at a rate that implies an effective free-space scattering cross section, σ(e) = (3.4 ± 0.5) × 10(-14) cm(-2), at least 25 times...

Although there is no consensus about the definition of professionalism, some generally recognized descriptors include knowledge, specialization, intellectual and individual responsibility, and well-developed group consciousness. In this study, Q-methodology was used to identify common viewpoints about professionalism held by nursing faculty and students, and four viewpoints emerged as humanists...

BACKGROUND Personally controlled health records (PCHRs), a subset of personal health records (PHRs), enable a patient to assemble, maintain and manage a secure copy of his or her medical data. Indivo (formerly PING) is an open source, open standards PCHR with an open application programming interface (API). RESULTS We describe how the PCHR platform can provide standard building blocks for net...

The Standards for Privacy of Individually Identifiable Health Information (Privacy Rule/current rule) took effect on April 14, 2001. As required by the Health Insurance Portability and Accountability Act (HIPAA), the Privacy Rule covers health plans, health care clearinghouses, and those health care providers who conduct certain financial and administrative transactions electronically. Most cov...
