Trimenia moorei (Oliv.) Philipson is an andromonoecious liane with >0.40 of the total flower buds maturing as bisexual flowers. Male and bisexual flowers are strongly scented with pollen, anther sacs and receptacle scars testing positively for volatile emissions. Scent analyses detect over 20 components. The major fatty acid derivative is 8-heptadecene, and 2-phenylethanol dominates the benzeno...

The analysis of the contents of 690 children’s drawings of the den­ t is t ’s o ffice was carried out w ith the aim of determ ining the presence of »fear-inducing« and »encouraging« elements in these drawings. The results showed that only 9% of children drew encouraging elements like flowers, pictures, decorations, etc. The presence of fear-inducing elements appea­ red to depend on: 1) children...

The influence of CaCl2 and borax on growth, yield, and quality of tomato was investigated during the years 2009 and 2010. The experiment was laid out with a randomized complete block design. Calcium chloride (0.3% and 0.6%) and borax (0.2% and 0.4%) solutions were applied as foliar sprays either alone or in combination and data were recorded for plant height, branches per plant, flowers per clu...

The volatile constituents of the flowers of Caralluma europaea (Guss.) N.E.Br (Apocynaceae) from Lampedusa Island were analyzed by a headspace GC method. The analyses allowed the identification and quantification of 41 compounds. The main components were, among the monoterpenoids, terpinolene (23.3%), alpha-terpinene (19.1%) and linalool (18.4%), whereas, among the carbonylic compounds the majo...

1. Many floral displays are visually complex, transmitting multi-coloured patterns that are thought to direct pollinators to nectar rewards. These ‘nectar guides’ may be mutually beneficial, if they reduce pollinators’ handling time, leading to an increased visitation rate and promoting pollen transfer. Yet, many details regarding how floral patterns influence foraging efficiency are unknown, a...

Observational studies assessing causal or non-causal relationships between an explanatory measure and an outcome can be complicated by hosts of confounding measures. Large numbers of confounders can lead to several biases in conventional regression based estimation. Inference is more easily conducted if we reduce the number of confounders to a more manageable number. We discuss use of sufficien...

We study the asymptotic behavior of a class of methods for sufficient dimension reduction in high-dimension regressions, as the sample size and number of predictors grow in various alignments. It is demonstrated that these methods are consistent in a variety of settings, particularly in abundant regressions where most predictors contribute some information on the response, and oracle rates are ...

Although the concept of sufficient dimension reduction has been proposed for a long time, studies in the literature have largely focused on properties of estimators of dimension-reduction subspaces in the classical “small p, and large n” setting. Rather than the subspace, this paper considers directly the set of reduced predictors, which we believe are more relevant for subsequent analyses, and...
