The purpose of the study was to compare basic fruit chemical composition of four highbush blueberry cultivars: ‘Spartan’, ‘Bluecrop’, ‘Jersey’ and ‘Blueray’. The plants were grown on plantation near Szczecin in the years 2001 – 2003. Basic chemical composition of fruit including total ash, crude fibre, total nitrogen, soluble solids, titratable acidity, dry weight and total polyphenol content w...

Cement is the most widely used material for construction. However, the cement production has a negative impact on the environment, as it is one of the contributors to global warming. The production of one ton of cement also produces approximately one ton of CO2. This encourages to the search for more environmentally friendly materials as cement replacement. The aims of this study are to compare...

A previous study demonstrated that paper sludges with high ash contents can be converted to ethanol by simultaneous saccharification and fermentation (SSF) or simultaneous saccharification and cofermentation (SSCF). High ash content in the sludge, however, limited solid loading in the bioreactor, causing low product concentration. To overcome this problem, sludges were de-ashed before SSF and S...

The present experiment was conducted to detect quality and level of the adulteration in milk collected from Dharchuni, Atani and Khamar bazar of Muktagacha Upazilla. Organoleptic parameters used to monitor the status of milk samples were color, flavor, taste, texture; physical parameter used was specific gravity; chemical parameters used were acidity, fat content, protein content, lactose conte...

The carbon emissions trading market has created a need for standard methods for the determination of biogenic content (chi(B)) in solid recovered fuels (SRF). We compare the manual sorting (MSM) and selective dissolution methods (SDM), as amended by recent research, for a range of process streams from a mechanical-biological treatment (MBT) plant. The two methods provide statistically different...

The objectives of the present research is to appreciate the effect of synthesizing parameters on setting time and workability of Fly ash based geopolymer paste . Locally available low calcium fly ash from a thermal power plant located near Kolkata, India, was used . Fly ash used are lignite coal based and falls under class F category. The broad areas of present research include: Manufacturing o...

Several investigations on the extraction of dioxins from soil and fly ash with supercritical fluid have been reported; however, few of them describe the influence of components on the extraction. We extracted dioxins from eight samples with different values of organic carbon content and surface area with supercritical CO(2) at a temperature of 463 K, a pressure of 40 MPa, and using 10% toluene ...

Proximate composition and phytochemical constituents of stems of A. africana and T. diversifolia (Asteraceae) were investigated. The stems of these species contain anti-oxidant, anticancer, anti-tumor, anti-viral, anti-inflammatory and anti-allergic properties which cures malaria, skin diseases, athlete’s foot, asthma, gonorrhoea and to stop bleeding. The stems of these two species revealed the...

The effective collection of fly ash in pulverized coal-fired plants which utilize electrostatic precipitators depends primarily on the effect of coal sulfur content, the gas temperature, and the carbonaceous content of the fly ash on the precipitator electrical power input. While the majority of precipitator installations are effective fly ash collectors, an abnormal change in any of the above ...

Various concentrations (0%, 0.5%, 1% and 1.5%) of β-CD were mixed with different fat contents (1%, 2.5% and 3%) of raw (unhomogenized) and homogenized milk at two mixing temperatures of 8 and 20°C. The cholesterol residue, fat, protein, lactose, solid nonfat (SNF), density, and ash content of milk were measured for each treatment. The results statistically analysed and showed that the cholester...
