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...

In our ongoing efforts to decipher the sequence and structural requirements in the flanking region of the CpG motif in phosphorothioate oligodeoxynucleotides (PS-oligos), we have examined the requirement of free 5'- and 3'-ends of PS-oligos on immune stimulation. Our model studies using 3'-3'-linked (containing two free 5'-ends) and 5'-5'-linked (containing two free 3'-ends) CpG-containing PS-o...

Introduction: Oxidative stress can impair the antioxidant protective capacity of the body, which is associated with decreased capacity of the body's internal defense system. There are some evidences that training and pumpkin seed (PS) consumption by different mechanisms have a protective effect on myocardial tissue by inhibiting oxidative stress. The aim of the present study was to investigate ...

the children aged under 5 years from vast african areas badly suffer from falciparum malaria and many of them die of this disease. therapeutic efficacy of anti-malaria drugs, especially pyrimethamine-sulfadoxine (ps) and chloroquine (cq) to falciparum malaria is frequently evaluated and reported in recent 10 years. unfortunately, to date, these widespread materials and researches have not been ...

introduction: the a im of this study is the evaluation of the effect of antimicrobial photodynamic therapy with radachlorin on staphylococcus aureus and escherichia coli. new windows are open in the antimicrobial field so-call photodynamic therapy that incorporates a nonpoisonous photosensitizer (ps) with innocuous special wavelength photons to excite the ps. methods: two strains of bacteria us...

in this paper, using pre-semi-open l-sets and their inequality, a new notion of ps-compactness is introduced in l-topological spaces, where l is a complete de morgan algebra. this notion does not depend on the structure of the basis lattice l and l does not need any distributivity.

Alkaline/surfactant/polymer (ASP) flooding has been extensively applied to enhancing oil recovery. As an oil displacement agent, pe1troleum sulfonate (PS) is widely used in ASP pilot experiments. It is very important to find a petroleum sulfonate with a high interfacial activity and low adsorption loss. Anionic surfactant petroleum sulfonate is synthesized in a single-tube film sulfonation reac...
