A new condensed form of the Fukui function, the natural orbital Fukui function (NOFF), is proposed and derived from natural bond orbital occupancy. It is defined as the change in natural bond orbital occupancy upon electronic perturbation (electron addition to, or depletion from, a molecular system). Applying NOFF to a series of cycloaddition reactions (e.g., [4 + 2] and [2 + 1] cycloadditions)...

Exports of hydrocarbons have been a great boon to the small state Brunei Darussalam and, as such, this paper argues that it provides an example country has not overly afflicted by “resource curse” or “Dutch disease”. But adversely affected oil and gas price volatility inevitably profound impact on hydrocarbon exporters, despite resorting futures markets. Given Brunei’s minimal non-hydrocarbon t...

introduction: enrichment of intact peripheral blood dendritic cells (dcs) has been done using rosette and immunomagnetic depletion techniques. material and methods: peripheral blood mononuclear cells were separated using ficoll density gradient centrifugation and t lymphocytes were depleted through reaction with aet- treated sheep red blood cells. the remaining cells were depleted from lineage ...

investigation of drought event has a great importance in the natural resources management and planning water resources management. in this research, the effect of the climate change on drought characteristics in northwest of iran was investigated using the hadcm3 model under a2 scenario. the statistical downscaling was executed using sdsm 4.2.9 and observed daily precipitation, observed predict...

ayurveda, the indian art of holistic medicine describes fasting in terms of upavasa and considers it as one among the depletion therapies.   besides the extensive explanations on the preventive purports of fasting, the classics have explicitly explained and exemplified the therapeutic importance of fasting while treating different diseases and dealing with different stages of the diseases. feve...

In stratified oligotrophic waters, phytoplankton communities forming the deep chlorophyll maximum (DCM) are isolated from atmospheric iron sources above and remineralized below. Reduced supply leads to a minimum in dissolved (dFe) near 100 m, but it is unclear if limits growth at DCM. Here, we propose that natural addition events occur regularly with passage of mesoscale eddies, which alter dFe...
