Physical and Combustion Characteristics of Briquettes Made from Water Hyacinth and Phytoplankton Scum as Binder
Autor: R. M. Davies, O. A. Davies
Publikováno v: Journal of Combustion, Vol 2013 (2013)
The study investigated the potential of water hyacinths and phytoplankton scum, an aquatic weed, as binder for production of fuel briquettes. It also evaluated some physical and combustion characteristics. The water hyacinths were manually harvested,

Effect of Briquetting Process Variables on Hygroscopic Property of Water Hyacinth Briquettes
Autor: R. M. Davies, O. A. Davies
Publikováno v: Journal of Renewable Energy, Vol 2013 (2013)
The knowledge of water resistance capacity of briquettes is important in order to determine how sensitive the produced briquettes are to moisture change during storage. The relative changes in length and diameter of briquettes during immersion in wat

Loss of sexual reproductive capacity has been proposed as a syndrome of domestication in vegetatively propagated crops, but there are relatively few examples from agricultural systems. In this study, we compare sexual reproductive capacity in wild (s

Mechanical Handling Characteristics of Briquettes Produced from Water Hyacinth and Plantain Peel as Binder
Autor: R. M. Davies
Publikováno v: Journal of Scientific Research and Reports. 2:93-102
Aims: The effect of process variable on shattering index and compressive strength characteristics of the water hyacinth briquettes were evaluated. Study Design: The experimental design for this study was 5 x 3 x 4 Randomized Complete Block Design. Pl

A New Look at Fluoride Varnishes
Autor: R. M. Davies, G. M. Davies
Publikováno v: Dental Update. 31:351-354
Fluoride varnishes have been available for over 30 years but there may be clinicians and dental public health practitioners who are unaware of the true level of effectiveness they provide in caries control. Under the headings of effectiveness, ease o

Relationship between area deprivation and the anticaries benefit of an oral health programme providing free fluoride toothpaste to young children
Autor: Helen V Worthington, Anthony S. Blinkhorn, G M Davies, Roger Ellwood, R M Davies, G. O. Taylor
Publikováno v: Community Dentistry and Oral Epidemiology. 32:159-165
OBJECTIVE: To determine the effectiveness of providing free toothpaste containing either 1450 or 440 ppm F on caries experience in 5-year-old children living in areas with different levels of material deprivation. DESIGN: Five-year, examiner-blind, r
