Alcoholato Complexes, Cobalt(II) Chlorides Alcoholato complexes of cobalt(II) chloride with the general formula, C0CI2 • x R O H (where R = Me, Et, Pr», Bu», Bu«, Bu* and Bu') have been synthesised by the reactions of anhydrous C0CI2 with an excess of the appropriate alcohols under reflux. Physicochemical studies such as electronic, infra-red spectra, magnetic and conductivity measurements have...

This paper presents work done to improve the representation in European decision support tools of physico-chemical forms of radiocontaminants released to the atmosphere from a major nuclear power plant accident. The task is to accommodate those types of scenarios where fuel particles are at play. A methodology with associated parameters has been developed to improve modelling of the aerodynamic...

The Harary index H can be viewed as a molecular structure descriptor composed of increments representing interactions between pairs of atoms, such that their magnitude decreases with the increasing distance between the respective two atoms. A generalization of the Harary index, denoted by Hk, is achieved by employing the Steiner-type distance between k-tuples of atoms. We show that the linear c...

Introduction There is now much information associating desirable and undesirable actions with chemical structure and constitution and physical properties. Hundreds of thousands of natural and synthesized compounds have been subjected to bacterial, animal and human toxicological studies and the information has been stored by computer and can be retrieved as an aid to literature search when embar...

www.meso.hr Introduction The traditional Croatian dry sausages are, in almost all cases, fermented sausages that undergo more or less prolonged process of smoking and drying–ripening before consumption. The most represented Croatian dry fermented sausage except for Slavonian Kulen is Slavonian homemade Sausage. Slavonian homemade Sausage is a traditional meat product from Eastern Croatia, Slavo...

The ability to locate promoters within a section of DNA is known to be a very difficult and very important task in DNA analysis. We document an approach that incorporates the concept of DNA as a complex molecule using several models of its physico-chemical properties. A support vector machine is trained to recognise promoters by their distinctive physical and chemical properties. We demonstrate...

the seeds of lepidium sativum (garden cress) were selected as a new source of hydrocolloid and some of its fundamental physico-chemical properties such as intrinsic viscosity and functional group were determined. ftir analysis showed that this polymer was composed of carbohydrate with functional carboxyl and hydroxyl groups. intrinsic viscosity was determined to be 1.33 ml/mg in water. the hydr...

A ZnO containing nano-hydroxyapatite/chitosan (n-HA/CS) cement was developed and its bone formation ability was investigated in vitro and in vivo. The physico-chemical properties of the cement were determined in terms of pH variation during and after setting, injectability and wettability. The results indicated that, the pH varied from 7.04 to 7.12 throughout the soaking of the cement in distil...

The effect of repeated heating process on edible oils namely, sesame oil (SO), sunflower oil (SFO) and palm oil (PO) with and without antioxidant, tertiary butyl hydroquinone (TBHQ) have been evaluated using ultrasonic velocity. The changes in physico-chemical properties of edible oils has been studied during repeated heating at 180 ± 5oC for 4 hrs/day and for 4 days. The effect of antioxidant,...

OBJECTIVE To evaluate physico-chemical properties and antimicrobial potential of indigenous honey samples against different reference strains including Escherichia coli ATCC 8739, Enterobacter aerogenes ATCC 13048, Pseudomonas aeroginosa ATCC 9027, Bacillus subtilis ATCC 6633, Staphylococcus aureus ATCC 25923, Salmonella typhi ATCC 14028, Klebsiella pneumonia ATCC 13883, Aspergillus niger ATCC ...
