The main goal of this study was to identify the treatment that increases the populations of spiders, which are effective predators in agroecosystems. In 2013 and 2014 the experimental eggplant (Solanum melongena L.) field was two different treatments, organic fertilizers and chemical fertilizer treatment, and in 2014 we surrounded organic fertilizer plots with the flowering plants mealy cup sag...

Plant compounds that induced Arthrobacter sp. strain B1B to cometabolize polychlorinated biphenyls (PCBs) were identified by a screening assay based on the formation of a 4,4'-dichlorobiphenyl ring fission product. A chemical component of spearmint (Mentha spicata), l-carvone, induced Arthrobacter sp. strain B1B to cometabolize Aroclor 1242, resulting in significant degradation of 26 peaks in t...

We give a simple, fast algorithm for hyperparameter optimization inspired by techniques from the analysis of Boolean functions. We focus on the high-dimensional regime where the canonical example is training a neural network with a large number of hyperparameters. The algorithm– an iterative application of compressed sensing techniques for orthogonal polynomials– requires only uniform sampling ...

The purpose of this study is to determine the specificity, or lack thereof, of the Duquenois-Levine (D-L) field test kit in the identification of marijuana. Out of the forty-two samples tested, patchouli, spearmint, and eucalyptus tested positive for marijuana using the D-L field test. From these results, it can be concluded that the test is non-specific and can yield false positives. Therefore...

Spearmint leaves (Mentha spicata L.) contain high levels of antioxidants that are known to protect against both exogenous and endogenous DNA damage. In this study, the protective effects of the hexane fraction (HF), chloroform fraction (CF) and ethyl acetate fraction (EAF) in an ethanol extract from M. spicata were evaluated against 4-nitroquinoline-1-oxide (4-NQO) induced chromosome damage and...

Perillyl alcohol is a monoterpene isolated from the essential oils of lavendin, peppermint, spearmint, cherries, celery seeds, and several other plants. In animal studies it has been shown to regress pancreatic, mammary, and liver tumors, to exhibit possible application as a chemopreventative agent for colon, skin, and lung cancer, and as a chemotherapeutic agent for neuroblastoma, and prostate...

Medicinal and aromatic plants are well appreciated for their antioxidant biocidal activities, while great variation on these activities can be related to the species, environmental conditions harvesting period. In present study, seasonal of activity, mineral content, yield chemical composition essential oils (EOs) sage (Salvia officinalis L.), sideritis (Sideritis perfoliata L. subsp. perfoliat...
