in this study, b12n12 nano ring has been selected because it consist of four 6-side rings and polar bonds b-n which in comparison with non-polar bonds c-c, is more suitable for the study of the absorption of other compounds. so reactivity and stability of benzene alone and in the presence b12n12 nano ring field checked. to determine the non-bonded interaction energies between benzene and b12n12...

Reaction of LSi-SiL (1) (L = PhC(NtBu)(2)) with diphenyl alkyne gave the first example of a room temperature stable 1,4-disilabenzene. The compound was characterized by means of single crystal X-ray diffraction studies. NICS (nucleus independent chemical shift) calculations showed that the compound has some aromatic character.

High-bandwidth TCP/IP networking places a significant burden on end hosts. We argue that this issue should be addressed by integrating simple network interface controllers (NICs) more closely with host CPUs, not by pushing additional computation out to the NICs. We present a simple integrated NIC design (SINIC) that is significantly less complex and more flexible than a conventional DMA-descrip...

Chemical stabilities of six low-energy isomers of C24 derived from global-minimum search are investigated. The six isomers include one classical fullerene (isomer 1) whose cage is composed of only five- and six-membered rings (56-MRs), three nonclassical fullerene structures whose cages contain at least one four-membered ring (4-MR), one plate, and one monocyclic ring. Chemical and electronic p...

PURPOSE Tannery workers are exposed to hazardous chemicals. Tannery work is outsourced to newly industrialized countries (NICs) where attention into occupational health hazards is limited. In this study, we investigated the skin exposure to hazardous chemicals in tannery workers and determined the prevalence of occupational skin diseases (OSDs) at tanneries in a NIC. METHODS A cross-sectional...

We explore the possibility of exploiting the computing power of chip-multiprocessor-based network interface controllers and switches in a system area network environment. We use stream processing applications as case studies to show that combining the compute-power of the host processor and a CMP-based NIC with 4 CPU cores can achieve speedup up to 1.30 even with the NIC running at one tenth th...

We empirically evaluate interrupt-related covert channels, in short IRCCs, a type of covert channel that leverages hardware interrupts for communication. The evaluation is based on an exploit of IRCCs that we implemented as a proof-of-concept. We use a combination of experimental evaluation and information-theoretic analysis to compute the bandwidth of the channel on a concrete system. Our anal...
