Pot marigold (Calendula officinalis) medicinal usage and cultivation

  Calendula pot marigold, is a genus of about 12 to 20 species of annual or perennial herbaceous plants in the daisy family Asteraceae, native to the area from Macaronesia East through the Mediterranean region to Iran. Calendula should not be confused with other plants that are also known as marigolds, such as corn marigold, desert marigold, or marsh marigold or plants of the genus Tagetes. The name Calendula...

Anti-inflammatory and analgesic activities of the aqueous leaf extract of Agave sisalana in rats

  Agave sisalana is gaining popularity in controlling gastro-intestinal parasites in chickens and treatment of local inflammatory conditions. However, little is known about its anti-inflammatory and analgesic properties. These properties were determined using the carrageenan, formaldehyde and histamine-induced oedema, as well as formalin, tail flick and acetic acid-induced pain tests. A....

An extension of fuzzy TOPSIS approach based on centroid-index ranking method

  The last few decades have seen a large number of methods for ranking fuzzy numbers; centroid-index based approaches are the most commonly used among them. However, there are some weaknesses associated with these centroid-indices. Therefore, this paper reviews several fuzzy numbers ranking methods based on centroid-indices and proposes a new centroid-index ranking method that is capable of effectively ranking...

Time independent seismic hazard analysis of the afar depression

  A Bayesian approach is applied to conduct a seismic hazard analysis in Afar Triple junction, resulting in a spatial distribution of the probability of exceedance in 100 years for earthquakes of MSK intensities VI and VII. The highest values of the exceedance probability for intensity VII are relatively scattered, showing spatial distribution that conforms with the RRR (rift-rift-rift) relative translational...

Effect of growth regulators on in vitro germination of Artemisia absinthium

  The present study was carried out to optimize the plant growth regulator conditions of callus formation, shoot regeneration and root induction, by using various explants of Artemisia absinthium. Leaf, hypocotyl and root explants of 1 to 3 weeks old in vitro grown seedlings were used for callogenesis and direct organogenesis at different concentrations and combinations of phytohormone added in...

Microbial contamination of currency counting machines and counting room environment in selected commercial banks

  A study was carried out to isolate and identify microorganisms associated with currency counting machines and counting room environment in four commercial banks operating in Anyigba, Kogi State, Nigeria. Samples were collected from currency counting machines and counting room environment in four commercial banks operating in Anyigba, Kogi State, Nigeria. The samples were processed by using standard methods...

Fuzzy-rough feature selection and a fuzzy 2-level complementary approach for classification of gene expression data

  Classification of gene expression data is an important issue in medical diagnosis of disease such as cancer. In this paper first Fuzzy-Rough Set theory is established to select relevant features for classification. This will be followed by proposing a new fuzzy 2-level complementary learning method. The Fuzzy-Rough Set is a mathematical tool which encapsulates the relevant but distinct concepts of fuzziness...

Recent trends on artificial neural networks for prediction of wind energy

  A variety of Artificial Neural Network models for prediction of hourly wind speed (which a few hours in advance is required to ensure efficient utilization of wind energy systems) is studied and the results are compared. Results in terms of simulation and prediction are obtained with Feed Forward Back Propagation Neural Networks (FFBPNN) which shows its performance better than other neural networks. Empirical...

Administration of Hydrocotyl bonariensis aqueous leaves extract regulates cardiovascular disease risk factors in galactose model of experimental cataractogenesis

  Reports had indicated that Hydrocotyl bonariensis contains phytochemicals that can be exploited for the development of anticataractogenic agent. In the present study we investigated the effects of administration of the plant’s leaves extract on some cardiovascular disease (CVD) risk factors in galactose model of experimental cataract. Twenty five (25) weanling rats randomly assigned to five...

Digital image watermarking using Learning Vector Quantization and hyperanalytic wavelet packet transform

  Digital watermarking techniques have been been largely applied into copyright protection and authentication of multimedia data. This paper proposes a novel digital watermarking algorithm for digital images by combining the hyperanalytic wavelet packet transform (HWPT) decomposition and Learning Vector Quantization (LVQ) neural network. For inserting watermark, the non-overlapping blocked original images are...
