We show that the diverse ecoregions of Madagascar share one distinctive climatic feature: unpredictable intra- or interannual precipitation compared with other regions with comparable rainfall. Climatic unpredictability is associated with unpredictable patterns of fruiting and flowering. It is argued that these features have shaped the evolution of distinctive characteristics in the mammalian f...

The proposed contribution describes a method for the detection and classification of harmonic transients, as they occur in electrical networks. The method uses, as bases, a special class of wavelet-packets, i. e. smooth biorthogonal sine and cosine-packets in order to find the best ’’Shannon-basis“. The algorithm is based on the minimization of Shannon‘s function for the decomposed wanted signa...

Large amounts of water, synthetic dyestuffs and chemicals are used in the wet processes textile finishing, at end these processes, liquors containing chemical substances create a waste load. For this reason, it is great importance to develop new wet-finishing that use less chemicals. purpose, layer-by-layer deposition method (LbL) was research as an environmentally friendly, sustainable can be ...

Today’s generation is becoming more environmentally conscious and shifting towards sustainable fashion. Unfortunately, synthetic dye being dominantly used as they produce bright color are cheap but hazardous to health compared natural chemical free, biodegradable eco-friendly. Role of has been increased preservation traditional heritage also one the important development goals which every count...

Microbiologically influenced corrosion (MIC) caused by sulfate-reducing bacteria (SRB) has been investigated in an oilfield injection water system. Strain CW-01 was isolated from an oilfield and strain CW-04 was isolated from biofilm dirt of pipeline walls. The strains were facultative anaerobes, non-motile, Gram-positive, pole flagellum, and spore-forming curved rods. The growth was observed o...

The effects of high temperatures on catalytic activity and binding abilities of crude Trichoderma reesei cellulases in solution and adsorbed to a cotton fabric were studied. Above optimum temperature of 508C, catalytic activities were severely diminished but the binding behaviour was not found to be adversely affected. In order to verify possible applications of cellulases adsorbed to cotton fa...

Liposomes are lipid-water systems that can carry hydrophobic and hydrophilic materials because of their amphiphilic structures. Application of liposomes in dyeing and finishing textiles is a new technology based on targeting and slow release which can lead to dyeing at lower temperature along with energy savings and lower environmental impacts. In this research work, a practical method for dyei...

ABSTRACT. Three compounds, phenyl propenone, p-tolyl and bromo phenylpropenone derivatives 3a-c were produced in good yields via condensation of acetophenone with dimethyl formamide acetal (DMFDMA) presence xylene as a solvent. Compounds 5a-f by coupling the enaminones diazonium chloride 4a or 4b. reacted acetone to create novel disperse dyes 9a-f. Mass spectra, (FT-IR), elemental analysis, 1H-...

Bio-based materials and new dyeing technologies have gained growing interest, as companies actively want to enhance their products sustainability remove environmental hazardous pollutants. This article describes for the first time waterless studies using supercritical carbon dioxide (SC-CO2) a natural anthraquinone dye emodin polylactide (PLA) polyester (PET) fabric colouration. The colour of d...

Reducing pollution in various industries such as textile is very important. In this paper, two parallel methods were used to reduce of the process and application dye. The first approach was selection plant-based dyes (Madder with botanical name Rubia tinctorum Reseda odorata) a tannin-based mordant (pomegranate peel Punica granatum). second extraction dyeing ultrasound media. efficiency madder...
