It is shown that there are a number of factors that are important to consider when planning the experiments on studying the trophic parameters of the caterpillars of the Gypsy moth, first of all, the population characteristics of the species including the sex and age structure that change annually. The final results of the study are also influenced by some procedures during the experiments, particularly, the duration (especially in the longest instars of the caterpillars) and volume of the sampling, which is supposed to grow as the caterpillars instar increases. The expediency is examined for using the individual growing of the caterpillars to study the species nutrition.
The Lymantria dispar nucleopolyhedrovirus (LdNPV) is one of the most important regulators of gypsy moth populations, but some aspects of its transmission remain poorly understood, particularly its high rate of spatial spread and ability to persist in low-density populations. We tested the role of...
The nettle caterpillar, Darna pallivitta (Moore) (Lepidoptera: Limacodidae), is an invasive pest with established populations on three Hawai'ian islands. Indigenous to Southeast Asia, D. pallivitta caterpillars cause defoliation of ornamental nursery stock and pose a human health hazard due to th...
Intravenous glucose tolerance test (IVGTT) provocations are informative, but complex and laborious, for studying the glucose-insulin system. The objective of this study was to evaluate, through optimal design methodology, the possibilities of more informative and/or less laborious study design of...
Technique of modification of basal faces Pt(hkl) by adatoms and epitaxial copper deposits is developed. Analysis of potentiostatic current transients of copper deposition/dissolution and atomic force microscopy showed that the activity of Pt(hkl) faces regarding the processes of copper nucleation...
Different aspects of applying the physical acoustics methods (in particular, internal friction method) in mechanics, optics, and radiation solid-state physics are considered. The results of acoustic experiments in situ upon plastic deformation and under the irradiation of crystals by high-energy ...

Understanding the universal aspects of human language structure requires comparison at multiple levels of analysis. While Evans Levinson (E L) focus mostly on substantive variation in language, equally revealing insights can come from studying formal universals. I first discuss how Artificial Gra...
Platyprepia virginalis caterpillars are dietary generalists and feed on multiple host species within a single day. We conducted field experiments to evaluate their performance on diets consisting of only their primary food, Lupinus arboreus, or diets consisting of L. arboreus plus other acceptabl...
Simulating a reduced gravity environment experienced in spaceships in a laboratory setting for studying different technical aspects (fluid transfer or propellant behavior, for example) is a primordial step prior to extraterrestrial explorations. We first present some results on boiling heat trans...
Based on findings of experiments with humans, non-human primates and rodents, it is commonly accepted that dopaminergic basal ganglia processes play a crucial role in procedural and sequential learning. Primal evidence for this hypothesis came from serial reaction time tasks (SRTT) studies, demon...
The analysis of the systematic errors in the determination of the energy of the particles of primary cosmic radiation that are inherent in the method for measuring extensive air showers (EASs) indicates the necessity of the exact inclusion of fragmentation in the nuclear interactions. The applica...
