The notion of absorbent ordered filters in implicative semigroupsis introduced, and its fuzzification is considered. Relations among (fuzzy) orderedfilters, (fuzzy) absorbent ordered filters, and (fuzzy) positive implicativeordered filters are stated. The extensionproperty for (fuzzy) absorbent orderedfilters is established. Conditions for (fuzzy) ordered filters to be (fuzzy)absorbent ordered ...

the aim of this study was to evaluate the effect of evaporative media as gas turbine intake air cooling method on pressure drop of cartridge air filters. this study performed under the laboratory condition, using stainless steel test rig with specified dimensions to investigate the role of evaporative media in air cooling as well as its effects on new and used cartridge filters (as representati...

background: diagnosis of cutaneous leishmaniasis (cl) is often made based on clinical manifesta­tion. correct diagnosis and identification of the parasite are crucial for choosing the effective treat­ment and for epidemiological studies. on the other hand, determination of leishmania species is nec­essary for designing appropriate control programs. diagnosis by pcr is becoming a 'gold standard'...

Escherichia coli MRE 600 ribosomes was found to inhibit translation of R17 RNA or poly(U) and initiation complex formation with R17 RNA. The effect of this protein on poly(U) translation was used as the basis of a simple and specific assay for its purification. The factor was purified to homogeneity by chromatography on DEAE-cellulose, hydroxyapatite, and Sephadex G-150, and its molecular weigh...

A haemic neoplasm occurs in populations of the common cockle Cerastoderma edule L. along the coast of Ireland. The morphology, epizootiology and distribution of the disease have previously been described. The aetiology of the neoplasm is unknown. In this study transmission of the neoplasm between cockles was accomplished using both whole neoplastic cells and neoplastic cell-free homogenates whi...

background: cigarette butts have been shown to release numerous kinds of chemicals such as heavy metals in water and may be a continual source of aquatic environments contamination after discarding. the objective of the present study was to determine the concentration of cd and pb in cigarette filters of different iranian and non-iranian brands in smoked and non-smoked samples. methods: ten dif...

Listgarten, M. A. (Harvard School of Dental Medicine and Forsyth Dental Infirmary, Boston, Mass.), W. J. Loesche, and S. S. Socransky. Morphology of Treponema microdentium as revealed by electron microscopy of ultrathin sections. J. Bacteriol. 85:932-939. 1963.-Broth cultures of a strain of Treponema microdentium were harvested on Millipore filters, fixed in osmic acid, and sectioned for electr...

Translation of total polysomal RNA from sarcoma 180 ascites cells in a wheat germ cell-free system produces two major polypeptides, A and B, with molecular weights of 50,000 and 45,000, respectively. Fractionation on Millipore filters or on oligo(dT)-cellulose leads to retention of the mRNA specific for protein A in the poly(A)-containing fraction and to accumulation of the B mRNA in the unadso...

By JAMES H. JANDL, RICHARD L. SI f sfoNS AND WILLIAM B. CAsTLE T HERE APPEAR to be two mechanisms whereby red cells are destroyed in vivo. First, they may undergo disruption or dissolution within the general circulation, as by the action of immune, bacterial, or chemical lysins, causing the clinical picture of “intravascular hernolvsis.” Second, and more commonly, red cells may be trapped or se...

The present study was undertaken to determine whether or not physical contact with the substratum is essential for the stimulatory effect of extracellular matrix (ECM) on corneal epithelial collagen synthesis. Previous studies showed that collagenous substrata stimulate isolated epithelia to produce three times as much collagen as they produce on noncollagenous substrate; killed collagenous sub...
