background: there are many studies focused on long or short storage time of epididymal sperm (eps) of different species. there are limited studies on preservation or cryopreservation of the domestic goat eps. objective: the aim of the present study was to evaluate the effects of ex vivo cold-storage on freezing of eps from goat (capra hircus). materials and methods: in a split-plot design the c...

The word biometry or its derivative, biometrics, depicts the need for close interdisciplinary research among big data systems, mathematics, and statistical sciences. Reports headed with biometrics are constantly increasing. Below, information provided by databases evidences expansion evolution from original main biological topics to new areas.

Extracellular microvesicles present in the epididymal fluid have been named epididymosomes. Many epididymosome-associated proteins are transferred to spermatozoa during their maturation in the excurrent duct. Epididymosomes are heterogeneous, with their size varying between 50 and 250 nm. Two distinct population of epididymosomes characterized by different protein compositions and diameters hav...

W E ARE pleased to present 14 papers in this special issue devoted to recent advances in biometric systems. A total of 78 papers were submitted for consideration for the special issue. Those that appear in this special issue result from a careful review process and consideration of timing for the special issue. Other papers, which were originally submitted for consideration for the special issu...

Nowadays, the use of biometric characteristics (e.g., palmprints, irises, fingerprints) is incrementing for individual recognition and many applications of biometrics are already available. Biometrics recognition has many advantages over the traditionally used methods (e.g., password, smart card), because biometric characteristics cannot be shared or forgotten, as it is inherently associated wi...

Personal identification and authentication is difficulty in all the systems. Shared secrets like Personal Identification Numbers or Passwords and key devices such as Smart Cards are not presently sufficient in few situations. These traditional tokens based systems may be easily stolen or lost. Biometrics is the only way of improving the capability to recognize the persons according to the physi...

Biometrics based authentication provides various advantages over other authentication methods, it has replaced the password based authentication and token based authentication. Biometrics plays a major role in Automated Teller Machine (ATM) system, E-Commerce, Online banking, Passports. The growth in electronic transactions has been increased tremendously; there is a greater demand for fast and...

The purpose of this study was to evaluate 2 methods of semen collection that could be used as terminal procedures in stallions with irreparable conditions, such as fractures or colic. Electroejaculation was attempted under general anesthesia. Forty-eight hours later, the ponies were castrated and 2 different epididymal sperm collection techniques were attempted by using a flushing or floating m...
