The distribution, sources and potential ecological risk of heavy metals in the sediment of lakes in eastern China and other areas of the world that have undergone rapid economic development have been widely researched by scholars. However, this is not true for heavy metals in the sediment of rump lakes in the arid regions of China and world-wide. Because of this, we chose Aibi Lake to serve as ...

Feather pecking is a problem in commercial laying hens, particularly in loose-housing systems, where many hens can be affected by only a few feather peckers. In addition, feather pecking can become an even larger problem if it spreads throughout the flock. There are several possible ways that feather pecking may spread. The simplest way is that one hen may damage the feathers of a hen, and anot...

Genetic parameters, genetic trends, and genetic progress of carcass traits were estimated for 12,447 Nellore individuals from different Brazilian herds. The following carcass traits were analyzed: visual body scores of conformation (CONF), precocity (PREC), and muscularity (MUSC); rump width (RW) and rump length (RL), body size (frame); and ultrasound evaluation of ribeye area (REA), backfat th...

This essay examines how ballad song was appropriated to present the demise of Rump Parliament and commemorate restoration monarchy. Songs not only provide a tune through which words can be performed but also weave together disparate texts memory past utterances performances. The "Cook Laurel" establishes mnemonic connection between parliamentarian figures ubiquitous rascals in Elizabethan folkl...

Left braces, introduced by Rump, have turned out to provide an important tool in the study of set-theoretic solutions quantum Yang–Baxter equation. In particular, they allowed construct several new families solutions. A left brace ( B , + ? ) is a structure determined two group structures on set : abelian and satisfying certain compatibility conditions. The main result this paper shows that eve...

Braces were introduced by W. Rump in 2006 as an algebraic system related to the quantum Yang—Baxter equation. In 2017, L. Guarnieri and Vendramin defined for same purposes a more general notion of skew left brace. 2020, Guo, H. Lang Y. Sheng gave definition what is Rota—Baxter operator on group. We connect these two notions follows. It shown that every group gives rise Moreover, brace can be in...

BACKGROUND First trimester growth restriction is associated with an increased risk of adverse birth outcomes (preterm birth, low birth weight and small for gestational age at birth). The differences between normal and abnormal growth in early pregnancy are small if the fetal size is measured by the crown-rump-length. Three-dimensional ultrasound volume measurements might give more information a...

The article presents materials on the study of cows’ exterior and meat productivity Aubrac gobies in acclimatization period third sixth generation animals conditions Northern Trans-Urals. It was established that as a result 18 years breeding, were formed enlarged type physique Cows had larger measurements shoulder height by 9.7cm, rump - 5.2 cm, slantwise body length 12.8 well chest depth 5.5cm...

to study of environmental effects (sex and age) on fleece traits of dromedary camel in sistan and balouchestan province, 48 male and female which rose in five cities (zahedan, zabol, khash, iran-shahr and ghabahar) belonging to three age groups (7 years) were measured. results indicated that there was not significantly different between sexes and age groups for all of fleece parameters, expect ...
