The title compound, C(17)H(18)NO(+)·I(-), is an adduct resulting from an intra-molecular Diels-Alder reaction of methallyl chloride with 3,4-dihydro-1-furylisoquinoline. The cation comprises a fused penta-cyclic system containing three five-membered rings (dihydro-pyrrole, dihydro-furan and tetra-hydro-furan) and two six-membered rings (tetra-hydro-pyridine and benzene). The five-membered rings...

The purpose of this study was to examine histologically the effects of propolis topical application to dental sockets and skin wounds. After topical application of either a 10% hydro-alcoholic solution of propolis or 10% hydro-alcoholic solution alone, cutaneous wound healing and the socket wound after tooth extraction were examined. The rats were sacrificed at 3, 6, 9, 15 and 21 days after the...

Microwave-assisted hydro distillation MAHD of eucalyptus citriodora. oil was investigated and a comparison was made with conventional hydro distillation. For MAHD, three process parameters; Microwave power, Extraction time and duration of dryness of sample were selected for the extraction. MAHD resulted in a shorter extraction time and better quality of oil compared to that in conventional hydr...

The anticancer potential of Cuscuta reflexa (whole plant extract), a holoparasitic plant collected from its host plant Euphorbia royleana was evaluated by testing its in vitro cytotoxicity and induction of cell death by apoptosis. Among three extracts (95% alcoholic, 50% hydro-alcoholic and aqueous extracts) and four fractions (n-hexane, chloroform, n-butanol and water) of alcoholic extract, th...

POWER ENGINEERING JOURNAL APRIL 2002 61 I nduction generators are commonly used for small hydro schemes due to advantages such as availability, low cost and robustness. The cost per kW of a single-phase generator is generally higher than a threephase generator. Hence a three-phase generator, which produces a single-phase output, is normally used. In order to minimise further the capital cost, c...

In Neurospora crassa three inducible enzymes are necessary to catabolize quinic acid to protocatechuic acid. The three genes encoding these enzymes are tightly linked on chromosome VII near methionine-7 (me-7). This qa cluster includes a fourth gene, qa-1, which encodes a regulatory protein apparently exerting positive control over transcription of the other three qa genes. However, an alternat...

A study was undertaken in Drosophila of the mutagenic properties of representatives of the various carcinogenic chemical series: alkylating agents, nitroso compounds, hydro carbons, aromatic amines, and urethan. Mutations arising from direct intramolecular DNA damage, such as point mutations and chromosome breaks leading to viable rear rangements, occurred only with the alkylating agents and th...

This chapter proposes a solution for the control of micro hydro power stations for island operation based on the characteristics of hydraulic turbine nonlinear model with the use of a self-excited induction generator. To control the frequency of the turbine it was considered the non-linear model applied to this type of turbine and the use of a frequency regulator, with characteristics of a prop...

Polycystic ovary syndrome (PCOS) is a reproductive and metabolic disorder in which thelevel of oxidative elements in blood rises. Green tea is a potent antioxidant since it containscatechins. In this study, the effect of hydro-alcoholic green tea extract on PCOS rats was examined.For PCOS induction, 96 mature Wistar rats were given estradiol valerate. After 60 days, therats were divided into fo...
