Kernel size is the main hazelnut quality parameter for consumption market. However, industrial purposes are destination cultivars. This work aims to identify aptitude relationships kernel size, and qualitative nut traits eligible enhance hazelnut’s commercial value. The of cv “Negret” “Pauetet” were assessed via in-shell shelled sizes two years. In-shell hazelnuts tested weight, shape, percent ...

ABSTRACT Brachiopod taxonomy is based on descriptions of shell morphology and key characters, but diagenesis generally modifies or erases some them, hindering brachiopod identification. Brachiopods that are taxonomically related usually present shells with similar appearance can differ in size (i.e., Rhynchonellata). Some aspects – for example the angular measurement curvature details microstru...

Dual-mode contrast agents (CAs) have great potential for improving diagnostics. However, the effectiveness of CAs is strictly related to both the solution adopted to merge the two agents into a single probe unit, and the ratio between the two agents. In this study, two dual-mode CAs for simultaneous magnetic resonance imaging (MRI) and ultrasound imaging (UI) were assessed. For this purpose, di...

Externally shelled cephalopods were important elements in open marine habitats throughout Earth history. Paleotemperatures calculated on the basis of the oxygen isotope composition of their shells can provide insights into ancient marine systems as well as the ecology of this important group of organisms. In some sedimentary deposits, however, the aragonitic shell of the ammonite or nautilid is...

Coevolution between parasites and hosts or predators and prey often involves multiple species with similar kinds of defenses and counter-defenses. Classic examples include the interactions between phytophagous insects and their host plants, thick-shelled invertebrates and their shell-crushing predators, and ungulates and their predators. There are three major hypotheses for the nonequilibrium c...

The effect of age on egg production was investigated in the domestic fowl. The rate of egg production was reduced with increasing age and the incidence of thin-shelled and cracked eggs was markedly increased. Older hens which remained in lay produced fewer but larger eggs than the younger birds. The ovaries of these two groups of hens were of similar appearance but the largest preovulatory foll...

Shelled pteropods (Gastropoda, Thecosomata, Euthecosomata) are a group of holoplanktonic gastropods that occur predominantly in the surface layers of the world's oceans. Accurate species identifications are essential for tracking changes in species assemblages of planktonic gastropods, because different species are expected to have different sensitivities to ocean changes. The genus Cuvierina h...

The manner in which a gastropod shell coils has long intrigued laypersons and scientists alike. In evolutionary biology, gastropod shells are among the best-studied palaeontological and neontological objects. A gastropod shell generally exhibits logarithmic spiral growth, right-handedness and coils tightly around a single axis. Atypical shell-coiling patterns (e.g. sinistroid growth, uncoiled w...

Extracellular and intracellular barriers typically prevent non-viral gene vectors from having an effective transfection efficiency. Formulation of a gene delivery vehicle that can overcome the barriers is a key step for successful tissue regeneration. We have developed a novel core-shelled DNA nanoparticle by invoking solvent-induced condensation of plasmid DNA (beta-galactosidase or GFP) in a ...

727 Abstract: The gelatin cap-sule shell may be soft or hard depending on their formulation. Capsules are intended to be swallowed whole by the patient. In instances where patients (especially children) are unable to swallow capsules, the contents of the capsule can be removed and added (e.g., sprinkled) on soft food immediately before ingestion. In the manufacture of pharmaceuticals, encapsula...
