The effect of glutamine and/or probiotic (Enterococcus feacium) supplements on piglet performance, intestines
structure, and microbial status was estimated on 181 piglets (16 litters) of Polish Landr...
Effects of γ-aminobutyric acid on the thymus tissue structure,antioxidant activity,cell apoptosis,and cytokine levels in chicks under heat stress
heat shock GABA chick thymus immune function development
2016/12/20
This study aims to investigate the effect of dietary γ-aminobutyric acid (GABA) on the development of thymus tissue structure and function in chicks under heat stress. One-day-old male Wenchang chicks...
Accuracy of Structure from Motion models in comparison with terrestrial laser scanner for the analysis of DBH and height influence on error behaviour
hand-held digital camera point cloud stem optimization image segmentation photogrammetry
2016/9/2
With the advantage of Structure from Motion technique, we reconstructed three-dimensional structures from two-dimensional image sequences in a circular plot with a radius of 6 m. The main objective of...

Eggshell quality is one of the most significant factors affecting poultry industry; it economically influences egg production and hatchability. Eggshell consists of shell membranes and the true shell ...
Effects of Three Feeding Systems on Production Performance, Rumen Fermentation and Rumen Digesta Particle Structure of Beef Cattle
Production Performance Rumen Fermentation Rumen Digesta Particle
2016/5/20
The effects of three different feeding systems on beef cattle production performance, rumen fermentation, and rumen digesta particle structure were investigated by using 18 Limousin (steers) with a si...
Genetic population structure of Bemisia tabaci in Spain associated with Tomato leaf curl New Delhi virus – short communication
whitefly begomovirus zucchini squash
2017/4/6
Tomato leaf curl New Delhi virus (ToLCNDV) originates from Asia where it is persistently transmitted by indigenous cryptic species of the whitefly Bemisia tabaci. The virus has recently invaded Spain,...
In rainforests,battle for sunlight shapes forest structure
rainforests sunlight shapes forest structure
2016/1/17
Despite their diversity, the structure of most tropical rainforests is highly predictable. Scientists have described the various sizes of the trees by a simple mathematical relationship called a power...
Differential diameter-size effects of forest management on tree species richness and community structure: implications for conservation
Differential diameter-size effects tree species richness
2015/11/13
In this paper we tested the hypothesis that logging effects in the adult tree
community reverberate upon the regeneration contingent. We examined the differences on
the tree community between forest...
