PREDICTION OF LARGE SOLAR FLARES BASED ON SHARP AND HIGH-ENERGY-DENSITY MAGNETIC FIELD PARAMETERS



Identification and chromosomal distribution of copia-like retrotransposon sequences in the coffee (Coffea L.) genome

The presence of copia-like transposable elements in seven coffee (Coffea sp.) species, including the cultivated Coffea arabica, was investigated.The highly conserved domains of the reverse transcriptase (RT ) present in the copia retrotransposons were amplified by PCR using degenerated primers.Fragments of roughly 300 bp were obtained and the nucle

First record of Megaselia scalaris (Loew) (Diptera: Phoridae) infesting laboratory stocks of mantids (Parastagmatoptera tessellata, Saussure)

We report the first record of Megaselia scalaris (Loew) infesting laboratory stocks of the praying mantis (Parastagmatoptera tessellata, Saussure).M.scalaris, the Pillow scuttle fly, is a cosmopolitan species with a broad niche as it performs as detritivore, facultative parasite, and parasitoid.M.scalaris larvae were found feeding inside adult mant

Experimental Investigation of Seepage Mechanism on Oil-Water Two-Phase Displacement in Fractured Tight Reservoir

As a type of unconventional oil and gas resources, tight sandstone reservoir has low permeability and porosity properties and thus is commonly necessary to develop through hydraulic fracturing treatment.Due to the coexistence of natural fractures and induced hydraulic fractures, the heterogeneity of reservoir permeability becomes severe and therefo
