Sperm quantity and quality during storage may be constraints acting on female fecundity and hence fitness. In Hymenoptera, the importance of sperm quality has rarely been considered, despite its central role in reproductive strategies and especially in sex ratio control. In these insects, fertilized eggs develop into females and unfertilized eggs into males. Experiments were conducted on the fe...

Pristine complex quaternary hydride (LiBH4/2LiNH2) and its destabilized counterpart (LiBH4/2LiNH2/nanoMgH2) have recently shown promising reversible hydrogen storage capacity under moderate operating conditions. The destabilization of complex hydride via nanocrystalline MgH2 apparently lowers the thermodynamic heat values and thus enhances the reversible hydrogen storage behavior at moderate te...

the Fast growth of data intensive applications has caused a changed in the traditional storage model. The server to disk approach is being replaced by storage area network (SANs), which enables storage to be externalized from the server, thus allowing storage devices to be shared among multiple servers by using threshold cryptography to secure data. A storage area network is a secure high speed...

Switched system-area networks enable thousands of storage devices to be shared and directly accessed by end hosts, promising databases and filesystems highly scalable, reliable storage. In such systems, hosts perform access tasks (read and write) and management tasks (storage migration and reconstruction of data on failed devices.) Each task translates into multiple phases of low-level device I...

BACKGROUND In cancer patients, allogeneic blood transfusion is associated with poorer prognosis, but the independent effect of the transfusion is controversial. Moreover, mediating mechanisms underlying the alleged cancer-promoting effects of blood transfusion are unknown, including the involvement of donors' leukocytes, erythrocytes, and soluble factors. METHOD Two syngeneic tumor models wer...

BACKGROUND Transfusion of blood at the limits of approved storage time is associated with lower red blood cell (RBC) post-transfusion recovery and hemolysis, which increases plasma cell-free hemoglobin and iron, proposed to induce endothelial dysfunction and impair host defense. There is noted variability among donors in the intrinsic rate of storage changes and RBC post-transfusion recovery, y...

Data Grids offer redundant and huge distributed storage capabilities, providing an ideal and secure place for the long-term preservation of digitized literary works and documents of artistic and historical relevance. In this demo, we are going to show how we deployed some digital repositories of ancient manuscripts making use of gLibrary, a grid-based system to host and manage digital libraries

A novel three-dimensional porous Si-MWNT heterostructure was designed to meet the demand of high-capacity and long-life lithium storage. This material presented a stable capacity above 1000 mAh g(-1) for nearly 200 cycles, which benefited from its highly porous structure combined with robust MWNT connections that accommodated the host volume change and improved the electric conductivity.

A universal and effective method for long-term storage of bacteriophages has not yet been described. We show that randomly selected tailed phages could be stored inside the infected cells at -80°C without a major loss of phage and host viability. Our results suggest the suitability of this method as a standard for phage preservation.

Storage systems play a significant role in data centers and there is an urgent need to efficiently store, retrieve and manage the ever increasing volume of data required by a variety of applications in the data center. Much of the stored data often contains a lot of redundancies at the block level that can be removed via de-duplication. The performance and fault-tolerance requirements also need...
