Traditional geostatistical space-time geostatistics is not able to take account of the generally strongly non-linear dynamics of multivariate space-time processes. To this effect physico-chemical transport models are in general more suitable. However, as the latter do not fully master the complexity of the processes they attempt to describe, either because of simplifying hypotheses or because t...

In this paper, we present new attacks on the redactable signature scheme introduced by Kundu and Bertino at VLDB ’08. This extends the work done by Brzuska et al. at ACNS ’10 and Samelin et al. at ISPEC ’12. The attacks address unforgeability, transparency and privacy. Based on the ideas of Kundu and Bertino, we introduce a new provably secure construction. The corresponding security model is m...

A competitive enzyme-linked immunosorbent assay (ELISA) for the detection of cypermethrin was developed. Two haptens, the trans- and cis-isomers of 3-[(+/-)-cyano-3-(2,2-dichloroethenyl)-2,2-dimethylcyclopropanecarbonyloxy]methyl]phenoxyacetic acid, were conjugated with thyroglobulin as immunogens. Four antisera were generated and screened against six different coating antigens. The assay that ...

Purpose: To study the immunosuppressant and immunopotentiating effects of ketoprofen on antibodyproducing cells. Methods: Mice were given ketoprofen at doses of 1 mg/kg/day and 5 mg/kg/day for seven days. Similarly polyinosinic–polycytidylic acid (Poly IC) and phosphate buffer saline (PBS) were used as positive and negative control, respectively, for seven days. After seven days, the mice were ...

An indirect competitive enzyme-linked immunosorbent assay (ELISA) has been developed and optimized for atrazine determination in soil at different depths (0-10, 10-20, and 20-30 cm) before and after 48 h of application, corn shoot and cow milk samples collected from Dina farm, Egypt. This assay was based on a specific polyclonal antibodies (PAb) raised by immunizing New Zealand rabbits with an ...

A competitive enzyme-linked immunosorbent assay (ELISA) for the chloronicotinyl insecticide imidacloprid was developed using a polyclonal antibody produced against a hapten conjugated through the imidazolidine to keyhole limpet hemocyanin. In the standard curve of imidacloprid, an IC(50) of 17.3 ng/mL was obtained using a competitive heterologous system at pH 10. Very low cross-reactivity was f...

Ϫ2 through 10 Ϫ7). The IC was consistently detected in dilutions 10 Ϫ6 through 10 Ϫ9. To determine interassay variation, we assayed 7 clinical samples positive for B. pertussis DNA within the linearity range of the assay 5 times on 5 different days (including reextraction each day). The SD calculated from the crossing points obtained was 0.08 –1.09. We determined in-traassay variation by assayi...

In this study, we investigated the anti-allergic action of mulberry fruit extract (MFE) or MFE in combination with naringinase (MFEN) in IgE-activated RBL-2H3 cells, and investigated the mechanisms responsible for the anti-allergic effects of MFEN. β-hexosaminidase release assay was used to measure the amount of β-hexosaminidase released from the cells, and ELISA was used to measure the levels ...

Using the idea of ic-open sets, we introduce and investigate topological qualities an ic-closure, ic-interior, ic-limit points, ic-derived, ic-border, ic-frontier, ic-exterior a set. Introduce concepts "ic-continuous mappings," "ic-open "ic-irresolute "ic-totally continuous "ic-homeomorphism," then look into some properties these mappings

Brevetoxin-1 (BTX-1), a marine toxin mostly produced by the dinoflagellatae Karenia brevis, has caused the death of marine organisms and has had numerous toxicological effects on human health. Hence, it is very necessary to develop a rapid, economical, and reliable immunoassay method for BTX-1 detection. In this study, two kinds of complete antigen were synthesized using the succinic anhydride ...
