Physicochemical properties of cellulose produced by local bacterial strain Gluconacetobacter xylinus KRE-65 by static and agitated fermentation methods was studied. Cellulose production by G. xylinus KRE-65 was carried out in coconut base medium with static and agitated fermentation methods. The dry weight, morphologi…
Tubular structures built from amphiphilic molecules are of interest for nano-sensing, drug delivery, and structuring of oils. In this study, we characterized the tubules built in aqueous suspensions of a cholesteryl nucleoside conjugate, cholesterylaminouridine (CholAU) and phosphatidylcholines (PCs). In mixtures with…
Self-organized graphite sheet nanostructures composed of graphene have been studied intensively. Carbon nanowalls and related sheet nanostructures are layered graphenes with open boundaries. The sheets form a self-supported network of wall structures with thicknesses in the range from a few nanometers to a few tens of…
Seven new lanostanoids, isolated from the sclerotia of Poria cocos , were elucidated to be (20 ξ )-16 α -hydroxy-3-oxo-24-methyllanosta-5,7,9(11),24(31)-tetraen-21-oic acid ( 1 ), (20 ξ )-3 β , 16 α , 29-trihydroxy-24-methyllanosta-7, 9(11), 24(31)-trien-21-oic acid ( 2 ), (20 ξ )-3 β , 16 α , 30-trihydroxy-24-methyll…
For the economic development and substance of a nation’s economy, energy is used as a prime mover. Future monetary development critically relies upon the long term availability of energy sources that are reasonable, accessible and environmental friendly. Microbial fuel cell represents a total approach to convert bio w…
Abstract — This paper presents a three-phase hybrid power filter based on artificial intelligence control approach. It consists of C-type passive filter in parallel with a shunt active filter that is controlled by an adaptive Neuro-Fuzzy inference system (ANFIS) controller. The active filter is based on a three-phase…
Ecdysteroids are known as regulators of moulting and reproduction in arthropods, and they can also be found in many plants as defensive agents against herbivores [1]. Our research group has recently reported their adjuvant antitumor activity in combination with various chemotherapeutics on several cancer cell lines, b…

A phytochemical investigation of the ethanol extracts of Taiwanese Vernonia cinerea L. resulted in the isolation of ten hirsutinolide-type sesquiterpenoids, including seven new ones, named vercinolides A˜G (1˜7). All structures were elucidated by a combination of detailed spectroscopic analyses (NMR and MS) and compar…
While there is a rich bibliography concerning the chemical composition of some genus belonging to Plumbaginaceae family [1 – 2], secondary metabolites of Armeria genus have slightly been investigated. This phytochemical study concerns the halophyte Armeria maritima Willd., with a specific focus on phenolic compounds w…
Any membrane developed under a standard set of conditions, such as temperature and relative humidity needs to be characterized. Any small change in the conditions of membrane preparation may lead to a signicant change in membrane structure and membrane morphology, which in turn may affect the membrane performance. The…

In this work Roman glass from Bracara Augusta, nowadays Braga (Portugal), were studied through their chemical composition, analyzing the major, minor and trace constituents using plasma-mass spectrometry (ICP-MS). The obtained data were statistically analysed, with the following statistical methodologies: (i) various…
АНАЛИЗ ИНФОРМАТИВНОСТИ КЛИНИЧЕСКИХ, ФУНКЦИОНАЛЬНЫХ, ЛАБОРАТОРНЫХ И ГЕНЕТИЧЕСКИХ ПОКАЗАТЕЛЕЙ ОЦЕНКИ СОСТОЯНИЯ ПАЦИЕНТОВ, ПЕРЕНЕСШИХ ИНФАРКТ МИОКАРДА, В ПРОГНОЗЕ ЭФФЕКТИВНОСТИ ИНТРАМИОКАРДИАЛЬНОЙ АУТОЛОГИЧНОЙ КЛЕТОЧНОЙ ТЕРАПИИ ХРОНИЧЕСКОЙ СЕРДЕЧНОЙ НЕДОСТАТОЧНОСТИ
The relativistic band structures of A N and A N B8–N chains have been calculated by the linear augmented-cylindrical-wave method, which is an extension of the augmented-plane-wave method for cylindrical polyatomic systems. The band structures of covalent monatomic chains of Group IV elements are characterized by σ(s),…
Objective: This study aims to prepare a new hydrophobic, water-soluble modified corn starch via sequential butyrylation and carboxymethylation and to evaluate its physico-mechanical and film-forming properties. Methods: Butyrylation was carried out in an aqueous suspension using 25%w/w butyric anhydride to yield corn…
The breakdown mechanism of a 100 nm-thick AlN thin film cold cathode structure was investigated during the field emission process, where the AlN film was synthesized by metalorganic chemical vapor deposition under low pressure on an n-type SiC substrate.
