the mathematical properties of nano molecules are an interesting branch of nanoscience forresearches nowadays. the periodic open single wall tubulene is one of the nano moleculeswhich is built up from two caps and a distancing nanotube/neck. we discuss how toautomatically construct the graph of this molecule and plot the graph by spring layoutalgorithm in graphviz and netwrokx packages. the sim...

Tetragallium(III) complex in [Ga4(L4-Py)2(dpm)6] ⋅ EtOH, with H3L4-Py=2-(hydroxymethyl)-2-(pyridin-4-yl)propane-1,3-diol and Hdpm=dipivaloylmethane, was investigated as a diamagnetic analogue of tetrametallic, propeller-like single-molecule magnets (SMMs). The chiral molecular structure partitions the six CH2 protons each tripodal (L4-Py)3− ligand into two diastereotopic sets. signals were clea...

The present experiment was carried out on twenty eight year old ber orchard planted under sodic soil condition, which is located at the Main Experiment Station Horticulture, Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya. objective to assess effect Plant growth regulators micro nutrient quality ber.The application different affected characters significantly i...

Agricultural industry is subjected to enormous environmental constraints, particularly due to salinity and drought. We evaluated the role of silicon (Si) in alleviating salinity and drought induced physio-hormonal changes in soybean grown in perlite. The plant growth attributes i.e., shoot length, plant fresh weight and dry weight parameters of soybean improved with elevated Si nutrition, while...

Xylopia aromatica is a native species from Brazil’s “Cerrado”, recommended for restoration ecology and also as a medicine. Its seeds have embryos with morphophysiological dormancy, making nursery propagation difficult. The objective of this study was to verify the efficiency of X-ray and tetrazolium tests for evaluating the viability of three seed lots, stored for different periods. All seeds w...
