Background: Alteration in the protein signatures of functionally immature testicular spermatozoa occurs during their journey through the epididymis. This leads to acquisition of sperm domain specific functions essential for successful fertilization. Epididymal sperm proteins are preferred targets for immunocontraception as well as in elucidating the causes of infertility. The Background of the ...

According to the original description by Rizzolatti and colleagues, the prerequisite of triggering the discharge of mirror neurons (MNs) is the interaction of the hand with an object. On the other hand, several studies reported that the MN system in humans can be activated also by non object-directed (intransitive) movements. This difference between human and monkey MN systems has been consider...

The formalism developed by Fayos and Sopuerta for isometries in vacuum spacetimes is generalised in three ways: to include the case of homotheties, to allow for a tetrad not aligned to the symmetry structure and to allow for a non-normalised tetrad. The new formalism is used to recover results by McIntosh and also applied to the particular cases of Robinson-Trautman and Kundt type N. AMS Classi...

Repairing of the cracks by fiber metal laminates (FMLs) was first done by some aeronautical laboratories in early 1970s. In this study, experimental investigations were done on the effect of repairing the center-cracked aluminum plates using the FML patches. The repairing processes were conducted to characterize the response of the repaired structures to tensile tests. The composite patches wer...

The concerns about possible antibiotic residues and disease resistance have given rise to great caution in the use of antibiotics in the animal industry and led to the removal of antimicrobial growth promoters from the diets. Among suitable natural alternatives, essential oils have gained considerable attention. Dietary acidification may be another alternative to antimicrobial growth promoters....
