Gagarina 11, Torun 87-100, Poland e-mail: [email protected] Nature is a source of some biomaterials like wood and chitin, which can be successfully transformed into chars of advanced structural/surface parameters. The manuscript is discursive and suggests that particular components of the mate...

Conformational transformations were investigated for molecules of kojic acid trapped in low-temperature argon and nitrogen matrixes. Two conformers, differing from each other by 120° rotation of the hydroxymethyl (-CH2OH) moiety, were found to be populated in freshly deposited matrixes, prior to any irradiation. Matrixes containing isolated monomers of kojic acid were irradiated with narrowband...

A composting toilet, using charcoal and rice husk as matrixes, requires inactivation treatment against pathogenic microorganisms derived from human feces before agricultural reuse. High pH conditions by adding calcium oxide (CaO) and wood ash is effective for lethal inactivation of pathogenic bacteria. However, quantitative information about application is limited. Therefore this study investig...

This paper presents the Lexicon-Grammar classification of Italian idioms that has been constructed on formal principles and, as such, can be exploited in information extraction. Among MWEs, idioms are those fixed constructions which are hard to automatically detect, given their syntactic flexibility and lexical variation. The syntactic properties of idioms have been formally represented and cod...

We have developed a new method for quantifying teicoplanin in complex matrixes, a receptor-antibody sandwich assay (RASA). The method is based on bioselective adsorption of teicoplanin onto microtiter plates coated with albumin-epsilon-aminocaproyl-D-alanyl-D-alanine, a synthetic analog of its biological target, and reaction with anti-teicoplanin antibodies. The sandwich complexes are detected ...

Rapid, sensitive, and accurate detection of analytes present in low concentrations in complex matrixes is a critical challenge. One issue that affects many biosensor protocols is the number and nature of the interferences present in complex matrixes such as plasma, urine, stool, and environmental samples, resulting in loss of sensitivity and specificity. We have developed a method for rapid pur...

Typical testors are a useful tool to do feature selection in supervised classification problems with mixed incomplete data. However, the complexity of computing all typical testors of a training matrix has an exponential growth with respect to the number of columns in the matrix. For this reason different approaches like heuristic algorithms, parallel and distributed processing, have been devel...

An efficient and accurate kinematics modeling and computational approach is proposed for the direct and inverse kinematics solving of the Stewart parallel mechanism. The problem is formulated directly as a pose -attitude modeling and differential calculation problems using Lie group and Lie algebra. The velocity and acceleration equations are derived out by using the Lie group differential on t...

In the present study, the adaptive neuro-fuzzy inference system (ANFIS) is developed for the prediction of effective thermal conductivity (ETC) of different fillers filled in polymer matrixes. The ANFIS uses a hybrid learning algorithm. The ANFIS is a class of adaptive networks that is functionally equivalent to fuzzy inference systems (FIS). The ANFIS is based on neuro-fuzzy model, trained wit...

Trace amounts of cashew nut protein can provoke severe allergic reactions in sensitive patients. Consequently, commercial food processors and regulatory agencies must be vigilant to prevent cashew nut cross-contamination among foods and ensure proper labeling. Toward this end, we have developed a sandwich enzyme-linked immunosorbent (ELISA) to detect the predominant cashew protein fraction (ana...
