Inundative releases of beneÞcial insects are frequently used to suppress pest insects but not commonly attempted as amethod of weed biological control because of the difÞculty in obtaining the required large numbers of insects. The successful establishment of a ßea beetle complex, mixed Aphthona lacertosa (Rosenhauer) and Aphthona nigriscutus Foundras (87 and 13%, respectively), for the control...

Green leafy vegetables (spinach and bathua) and pulses (green pea and bengal gram) are widely consumed and hold an important place in the diet of people of India. Vegetarians who consume a greater amount of vegetables will have a higher intake of oxalate, which may reduce calcium availability. The objectives of this present research were to investigate the effect of different domestic cooking a...

Inundative releases of beneficial insects are frequently used to suppress pest insects but not commonly attempted as a method of weed biological control because of the difficulty in obtaining the required large numbers of insects. The successful establishment of a flea beetle complex, mixed Aphthona lacertosa (Rosenhauer) and Aphthona nigriscutus Foundras (87 and 13%, respectively), for the con...

The objective of this study was to analyze the nutritional, antinutritional and mineral compositions of eight locally available underutilized green leafy vegetables of Sonitpur district of Assam, India. Moisture and ash of the green leafy vegetables were in the range of 71.7498.20 g / 100 g and 8.23-26.01 g / 100 g respectively. Fiber was higher in Basella rubra (8.61 g / 100 g) and lower in Mo...

Leafy spurge (Euphorbia esula-virgata), a native of Eurasia, is a serious invasive weed of grasslands of the northern Great Plains of the U.S. and prairie provinces of Canada. Leafy spurge is very difficult to control with herbicides, insect biological control agents, and other cultural practices. Previous field investigations revealed pathogen–insect interactions on the roots of leafy spurge l...

Transcription factors (TFs) are key players in evolution. Changes affecting their function can yield novel life forms but may also have deleterious effects. Consequently, gene duplication events that release one gene copy from selective pressure are thought to be the common mechanism by which TFs acquire new activities. Here, we show that LEAFY, a major regulator of flower development and cell ...

We prove that the d-dimensional hypercube, Hd, with n = 2 d vertices, contains a spanning tree with at least 1 ? 2 log 2 n ? o 1 log n n + 2 leaves. This improves upon the bound implied by a more general result on spanning trees in graphs with minimum degree , which gives 1 ? O(log log n) log 2 n n as a lower bound on the maximum number of leaves in spanning trees of n-vertex hypercubes.

background: the sources of radioactivity in the environment have natural, terrestrial and extraterrestrial, and anthropogenic origins. plants may get radioactive nuclides in two ways: (i) by the deposition of radioactive fallout, (ii) by absorption from the soil. materials and methods: the concentrations of the natural radionuclides (226ra, 228ra, 40k) and the artificial radionuclide (137cs) in...
