To explore soil nutrients and moisture changes in different karst mountain agroforestry, the plateau mountains of Southern China Karst, we used secondary tree irrigation forest (C) as a reference for our study selected four mixed agroforestry species (walnut + maize potato (HYM), walnut (HTY), poplar ryegrass (YSH), (YMH)) comparison. First, change characteristics were monitored situ field. Sec...

the cypress tree mealybug, planococcus vovae (nasonov) (hem., pseudococcidae) is one of the most important pests of cypress trees, especially cupressus semprevirens fastigiata l. in iran. a survey was carried out to determine the natural enemies of cypress tree mea-lybug in tehran province, during 2004-2005. as a result of this study, 17 species of preda-tors, parasitoids and hyperparasitoids b...

Three novel text vector representation approaches for neural network based document clustering are proposed. The first is the extended significance vector model (ESVM), the second is the hypernym significance vector model (HSVM) and the last is the hybrid vector space model (HyM). ESVM extracts the relationship between words and their preferred classified labels. HSVM exploits a semantic relati...

The objective of this work was the identification and differentiation of Trichogramma exiguum Pinto and Platner species, T. pretiosum Riley, and T. galloi Zucchi using sequences of the ITS2 region of ribosomal DNA. After extracting DNA from the studied species, a PCR reaction was performed, where the amplified samples were subjected to sequencing. The sequences obtained were submitted to a simi...

A wide range of imaging and spectroscopy technologies is used in medical diagnostics, quality control in production systems, military applications, stress detection in agriculture, and ecological studies of both terrestrial and aquatic organisms. In this study, we hypothesized that reflectance profiling can be used to successfully classify animals that are otherwise very challenging to classify...
