This experiment assessed the yield and growth performance of the fodder tree planting in the community forest focusing on Artocarpus lakoocha, Bahunia purpurea. Major variables analyzing the yield and growth of the species such as dbh, height, green weight of the foliage was measured. After analyzing the data, Artocarpus lakoocha was found to be good yielding and growth performing species as co...

We assessed the effect that varying patterns of biomass allocation had on growth of ponderosa pine (Pinus ponderosa) growing in the desert climate of the Great Basin and the montane climate of the eastern Sierra Nevada. Prior work established that desert trees have lower leaf: sapwood area ratios than montane trees (0.104 and 0.201 M2/ cm2, respectively) and proportionally greater stem respirat...

The four-parameter Johnson's SB (JSB) and three-parameter Weibull distributions have received significant attention in the field of forestry for characterising diameters at breast height (DBH). This study suggests Bayesian method estimating parameters JSB distribution. maximum likelihood approach uses iterative methods such as a Newton–Raphson (NR) algorithm maximising logarithm function. Howev...

We have investigated the specification of noradrenergic neurotransmitter identity in neural crest stem cells (NCSCs). Retroviral expression of both wild-type and dominant-negative forms of the paired homeodomain transcription factor Phox2a indicates a crucial and direct role for this protein (and/or the closely related Phox2b) in the regulation of endogenous tyrosine hydroxylase (TH) and dopami...

The objective of this study was to select Pinus kesya progenies by the estimation of genetic parameters using the method of restricted maximum likelihood (Reml) and prediction of additive genetic values by the best linear unbiased prediction (Blup). The Pinus kesya progeny test was installed in randomized blocks, which consisted of 30 progenies and three replications. The twenty-year-old trees ...

The roles of norepinephrine (NE) and epinephrine in behavior were investigated by targeted disruption of the dopamine beta-hydroxylase (Dbh) gene, thereby eliminating these compounds in vivo. Most heterozygous pups born to Dbh-/- females died within several days of birth and were often found scattered within the bedding. Potential causes including deficits in olfaction and lactation were not ap...

Sustained attention is modulated by the neurotransmitter noradrenaline. The balance of dopamine and noradrenaline in the cortex is controlled by the DBH gene. The principal variant in this gene is a C/T change at position -1021, and the T allele at this locus is hypothesised to result in a slower rate of dopamine to noradrenaline conversion than the C allele. Two hundred participants who were g...

Pharmacological studies in mammals suggest that norepinephrine (NE) plays an important role in promoting arousal. However, the role of endogenous NE is unclear, with contradicting reports concerning the sleep phenotypes of mice lacking NE due to mutation of dopamine β-hydroxylase (dbh). To investigate NE function in an alternative vertebrate model, we generated dbh mutant zebrafish. In contrast...
