reactive oxygen species (ros) generation, induced by the cryopreservation process, can be responsible for mammalian sperm damage. curcumin is known as an effective antioxidant against oxidative stress. the aim of this study was to evaluate the effects of curcumin on sperm count, motility and viability, semen total antioxidant capacity and dna integrity of rat spermatozoa during semen freeze-tha...

Abstract Is academic integrity research presented from a positive standpoint? This paper uses Natural Language Processing (NLP) techniques to explore data set of 8,507 papers published between 1904 and 2019. Two main are used linguistically examine titles: (1) bigram (word pair) analysis (2) sentiment analysis. The sees the three bigrams in titles as being “academic integrity” (2.38%), dishones...

This paper argues that syllables may be divided by feet, based on an analysis of Banawá, an Arawan language of the Brazilian Amazon. This result is important for phonological theory because it improves our understanding of the variable roles of syllables and moras in the phonological systems of individual languages and because it underscores the urgent need for more fieldwork on the prosody of ...

Background: Following the expansion of human infertility, different procedures have been utilized for separation of normal sperm during ICSI (Intra cytoplasmic sperm injection). Hypo-osmotic swelling test (HOST) is one of the tests which have been introduced for assessment of integrity of sperm membrane when confronted with hypo osmotic condition. This test may also reflect intracellular organe...

Designing cryptographic mechanisms as well as products and systems that embed cryptographic components is a challenging task. This task will become increasingly hard as software technology and systems evolve and as the new computational environment becomes more distributed, more diverse, and more global. In order to enable the inclusion of cryptographic components in the future infrastructure a...

Transformation of a source schema with its conforming data to a target schema with its conforming data is an important activity in XML as two schemas in XML can represent same real world information. Specifically in XML data integration, transformation of a source to a target is regarded as an important task. An XML source schema can often be defined with XML key which is an important integrity...

A dynamic constraint expresses conditions that involve facts of two or more states of the database. Since the database is expected to satisfy such conditions, a fundamental issue about integrity constraints is their enforcement. Many methods have been developed in this respect. The purpose of this paper is to present a brief survey of methods for dynamic constraint definition and enforcement. A...
