Effects of four tropical plant (Aframomum melegueta, Zanthoxylum zanthoxyloides, Piper guineense and Eugenia aromatica) were investigated under tropical laboratory storage conditions for the protection of cowpea seeds against insect infestation. The plant materials were pulverised into fine powder after air drying and admixed with 20 g of cowpea seeds at the ...

BACKGROUND: Botanicals insecticides has remained the major weapons amongst tropical zones farmers to combat hexapods infestation of stored cowpea seeds in lieu of expensive synthetic chemical insecticides that have toxic effects on our environment. OBJECTIVES: Deterrence of cowpea bruchid oviposition and emergence on seeds treated with Cheese wood, Alstoni...

Canola (Brassica napus L.) is one of the important sources of vegetable oils and protein-rich meals. Canola ranks third in global production of oilseed crops and fifth among economically important crop next to wheat, rice, maize, and cotton. The present work was undertaken with the aim to investigate the effect of Ethylmethyl sulphonate (EMS) on the yield contributing characters of brassica nap...

Black mold disease caused by Aspergillus niger V. Tiegh. is the most devastating infection occurs in onions (Allium cepa L.) under field and store conditions. The use of biocontrol agents is ecofriendly approach for controlling seedborne and soilborne diseases compared to the use of toxic synthetic fungicides. This study has been designed to assess the contamination levels of onion seeds with A...

747 1941-Lathyrus sativus peas, spastic paraparesis; the toxic agent was identified to be 1)-JY-methylamino-Lalanine (BMAA); 1953-Guamalian type of Parkinsonism, caused by the seeds of Cycas circinalis; the toxic agent was identified as 1)-JY-oxalylmethylamino-Lalanine (BOMAA); 1948-hexachloraphene encephalopathy; 1950-monosodium glutamate in baby food; 1953-Minamata disease, mercury encephalop...

Cerebral β-amyloidosis and associated pathologies can be exogenously induced by the intracerebral injection of small amounts of pathogenic Aβ-containing brain extract into young β-amyloid precursor protein (APP) transgenic mice. The probable β-amyloid-inducing factor in the brain extract has been identified as a species of aggregated Aβ that is generated in its most effective conformation or co...

A time-constrained viral marketing campaign allows a business to promote a product or event to social network users within a certain time duration. To perform a time-constrained campaign, existing works select the duration of the campaign, and then a set of k seeds that maximize the spread (expected number of users to which the product or event is promoted) for the selected duration. In practic...

We present a method for initialising the K-means clustering algorithm. Our method hinges on the use of a kd-tree to perform a density estimation of the data at various locations. We then use a modi cation of Katsavounidis' algorithm, which incorporates this density information, to choose K seeds for the K-means algorithm. We test our algorithm on 36 synthetic data sets and compare with 25 runs ...
