A comprehensive understanding of the dynamic behavior a tree can play key role in stability analysis. Indeed, through an engineering approach, living be modeled as mechanical system and monitored observing its properties. In current work, procedures identification used civil are applied to case study black locust (Robinia pseudoacacia L.). The was instrumented with 13 seismic, high-sensitivity ...

In Hungary, the black locust (Robinia pseudoacacia L.) can be considered as most important fast-growing, stand-forming introduced tree species. Due to its positive growing technological characteristics well wood utilization possibilities, at present, is widely planted species in covering 25% of country’s total forest area. One tasks ahead Hungarian growers improve quality stands with introducin...

in this research, seeds of iranian carob trees grown wild in kazeroon city (fars province) were used to extract iranian locust bean gum as a seed galactomannan. chemical composition, solubility, and rheological properties of crude and purified gums were investigated and compared with a commercial (sigma) locust bean gum (lbg) sample. chemical composition of the purified iranian lbg was similar ...

Many migratory bird species, several of which are in severe decline, and African residents spend the northern winter Sahel, by nature a huge savannah, half has been converted into farmland. We analyse impact such large-scale changes on birds. On average, woody cover is 38% lower farmland than savannah. More critically, farmers have drastically changed vegetation communities their In arid semi-a...

Background and Purpose: Black locust (Robinia pseudoacacia L.) is a valuable species native to North America and today widely planted throughout the world for biomass production. In Hungary, where Robinia has great importance in the forest management, the clones have been selected for plantations on good, medium and poor quality sites. To conserve the identity, superior clones are vegetatively ...

Exudation, (86)Rb transport, and water permeability were examined in excised roots of honey locust (Gleditsia triacanthos L.) treated by removing the tip 2 mm (tip-cut 2 mm) or tip 8 mm of the root, or by adding kinetin, or by both treatments. Tip removal increased the rate of exudation. Kinetin, 5 x 10(-6)m, inhibited exudation and Rb transport in tip-cut 2-mm roots; the inhibition was reversi...

The contribution of natural products to the drug-discovery pipeline has been remarkable since they have served as a rich source for drug development and discovery. Natural products have adapted, during the course of evolution, optimum chemical scaffolds against a wide variety of diseases, including cancer and diabetes. Advances in high-throughput screening assays, assisted by the continuous dev...

The locust is well known for its ability to jump large distances to avoid predation. This class sets out a series of investigations into the mechanisms underlying the jump enabling students to bring together information from biomechanics, muscle physiology, and anatomy. The nature of the investigation allows it to be undertaken at a number of levels of complexity from relatively simple comparat...

Transgenerational effects of parental experience on offspring immunity are well documented in the vertebrate literature (where antibodies play an obligatory role), but have only recently been described in invertebrates. We have assessed the impact of parental rearing density upon offspring disease resistance by challenging day-old locust hatchlings (Schistocerca gregaria) from either crowd- or ...

Rhythmic behaviours such as breathing, walking or flying are now understood to be generated by the interplay between patterns of neural activity generated in the central nervous system and sensory inputs. Many of the pioneering insights into the generation and control of rhythmic motor patterns were made by studying the neural circuits generating the locust flight motor pattern. Malcolm Burrows...
