This paper’s approach to semantic integrity management is that in order to maintain an integrity constraint, some variables of the constraint may be operated on while others may not This defines integrity dependencies between vsiables. Various examples of integrity dependencies and their meanings are discussed. In addition to corresponding to real world practice, integrity dependencies can be u...

background: when male animals die, spermatozoa within the body of animal will be degenerated. because of unique chromatin structure of sperm, maybe this degeneration is different from other cells. however there is not any research which considered directly the integrity of sperm dna by keeping the cadaver in refrigerator. objective: the aim of this study was to assess viability, total motility ...

Abstract COVID19 forced most education institutions to move their provisions digital platforms almost overnight ensure continued learning for students. Variable factors relating educational technologies, ease of use, accessibility and funding meant the process was more challenging some than others. However even agile well-prepared faced a hurdle during remote when it came integrity in assessing...

Background: Intracytoplasmic sperm injection (ICSI) can be considered the solstice in vitro insemination technique because it has powerfully allowed the treatment of male factor infertility, but in this procedure, except visual morphological selection, there is no standardization for sperm selection. Recently, hypo osmotic swelling test (HOST) has been proposed to have the potential to select i...

Semantic properties that reflect quality criteria can be modeled by integrity constraints. Violated instances of constraints may serve as a basis for measuring quality. Such measures also serve for monitoring and controlling quality impairment across changes.

We investigate how belief change operations can be eeec-tively constructed. To that end we suppose given a set of laws (alias integrity constraints) together with a relation of dependence between formulas.
