Seasonal changes in the biochemical parameters such as protein, carbohydrate, lipid and ash besides moisture content in the muscle of Lagocephalus spadiceus (Richardson, 1845) and Lagocephalus lunaris (Bloch and Schneider, 1801) has been carried out during January to December 2009. The percentage composition of moisture, protein, carbohydrate, lipid and ash contents showed variations in their a...

This research is a part of a wide range investigation on the use of flue gas desulphurisation (FGD) in construction applications. It reports some results on the porosity and pore size distribution of cement paste containing varying amounts of fly ash-gypsum blends as partial replacement of cement. The cement was replaced with 25% of different blends of fly ash and gypsum. The gypsum content ran...

Galanthus rizehensis Stern (Amaryllidaceae) was collected from Maçka, Trabzon during flowering and fruiting seasons. Quality control studies and quantitative determination of lycorine were carried out on the prepared specimens. In this respect, assays for humidity, total ash, sulphated ash, hydrochloric acid-insoluble ash were performed on each drug specimen. The total alkaloidal content of G. ...

This paper investigates mortars consisting of various circulating fluidized bed combustion (CFBC) bed ash contents. The CFBC bed ash used in this study was obtained from Taiwan’s petroleum industry. This study presents experimental results on the flowability, compressive strength, drying shrinkage, scanning electronic microscopy (SEM) and mercury intrusion porosimetry (MIP) of mortar samples co...

The calcined petroleum cokes are used in production of aluminum anode-grade, graphite electrode, needle-grade, titanium dioxide pigments. Petroleum coke (green and calcined) is produced by the high pressure thermal decomposition of heavy petroleum process streams and residues. Green coke undergoes additional thermal processing to produce calcined coke. Various properties of calcined cokes from ...

The effect of storage time on some properties of groundnut shell briquette with 5, 10, 15 and 20% binder (cassava gel) was studied. The briquettes were prepared using a motorized briquetting machine. The moisture content, durability rating, water penetration, calorific value and the ash content were determined after every 30 days for 6 months. The results reveals that the moisture content of br...

The effect of cooking methods on some proximate properties of sweet potato (Ipomoea batatas L) was investigated. With the initial properties of the fresh sweet potatoes (sample A) determined, 600g each of samples B, C and D were boiled peeled, boiled unpeeled and roasted unpeeled respectively. The properties determined for the samples are moisture content, ash, fibre, protein, fat, carbohydrate...

The Tennessee Valley Authority Kingston coal ash spill in December 2008 deposited approximately 4.1 million m(3) of fly ash and bottom ash into the Emory and Clinch River system (Harriman, Tennessee, U.S.A.). The objective of this study was to investigate the impact of the ash on surface water and sediment quality over an eighteen month period after the spill, with a specific focus on mercury a...
