The control of chemical, morphological, textural and magnetic properties developed in activated carbons (MACs) from industrial food waste, was achieved. process parameters involved a sustainable optimized one-step activation route, based on the circular economy model, played an important role its influence studied, offering interesting outstanding results. Magnetite crystals were formed MACs su...

Objective. To examine whether density gradient centrifugation (DGC) alone or its combination with annexin V magnetic-activated cell sorting (DGC-MACS) can be used to process semen samples from infertile male patients poor sperm quality prior subjecting these freeze/thaw in order optimize the outcomes of freezing. Methods. This study enrolled sixteen <math xmlns="http://www.w3.org/1998/Math/Math...

SipHash is a family of pseudorandom functions optimized for short inputs. Target applications include network traffic authentication and hash-table lookups protected against hash-flooding denial-of-service attacks. SipHash is simpler than MACs based on universal hashing, and faster on short inputs. Compared to dedicated designs for hash-table lookup, SipHash has well-defined security goals and ...

Background Sperm preparation before assisted reproductive techniques is very important for obtaining successful fertilization and pregnancy. During ICSI technique, sperms are selected based on viability and morphology. But this selection did not guarantee integrity of sperm DNA. Therefore, novel sperm selection procedures are introduced for selection of sperm with low DNA damage. One of these p...

While standard message authentication codes (MACs) guarantee authenticity of messages, they do not, in general, guarantee the anonymity of the sender and recipient. For example it may be easy for an observer to determine whether or not two authenticated messages were sent by the same party even without any information about the secret key used. However preserving any uncertainty an attacker may...

background: the immunomagnetic separation technique is the basis of monocyte isolation and further generation of monocyte-derived dendritic cells. objective: to compare the efficiency of monocyte positive and negative separation, concentration of beads, and their impact on generated dendritic cells. methods: monocytes were obtained using monoclonal antibody-coated magnetic beads followed the fi...
