Global Software Development (GSD) has gained popularity lately and challenges and research opportunities appeared. The development team’s physical distribution imposes challenges related to awareness support during collaboration. According to the 3C collaboration model, awareness intermediates communication, cooperation, and coordination. In this paper, we present a systematic review of the lit...

The synthesis of the 2'-deoxyadenosine analogues 1b, 2b, and 3c modified at the 7- and/or 2-position is described. The effect of 7-chloro and 2-methylthio groups on the duplex stability is evaluated. For that, the nucleosides 1b, 2b, and 3c were converted to the corresponding phosphoramidites 15, 19, and 22, which were employed in the solid-phase oligonucleotide synthesis. In oligonucleotide du...

I present 1.5and 8.4-GHz observations with all configurations of the NRAO VLA of the wide-angle tail source 3C 130. The source has a pair of relatively symmetrical, wellcollimated inner jets, one of which terminates in a compact hot spot. Archival ROSAT PSPC data confirm that 3C 130’s environment is a luminous cluster with little sign of sub-structure in the X-ray-emitting plasma. I compare the...

All data in the B band for quasar 3C 345 have been compiled into a light curve from twenty one publications, dating back to 1896; 1642 values are available. The light curve shows that 3C 345 is very active and exhibits very complicated nonsinusoidal variations. Using this data we have found a period of 10.1±0.8 years (or 21.8±1.5 years) for the outbursts in 3C 345. This value is in good agreeme...

The MAGIC telescope observed the region around the distant blazar 3C 66A for 54.2 hr in 2007 August–December. The observations resulted in the discovery of a γ-ray source centered at celestial coordinates R.A. = 22312 and decl.= 430.7 (MAGIC J0223+430), coinciding with the nearby radio galaxy 3C 66B. A possible association of the excess with the blazar 3C 66A is discussed. The energy spectrum o...

we have performed density functional theory investigations on the adsorption properties of ammonia molecule on the undoped and n-doped tio2 anatase nanoparticles. we have geometrically optimized the constructed undoped and n-doped nanoparticles in order to fully understand the adsorption behaviors of ammonia molecule. for tio2 anatase nanoparticles, the binding site is preferentially located on...

First-principle calculations have been investigated to study the adsorption of the molecules (SO2, CO, NH3, CO2, NO2, and NO) on the surface of mono boron (B) B-doped and dual B-doped graphene sheets to explore their potential applications as sensors. Our findings indicate that the adsorption of (CO and NH3) on B-doped graphene and (CO and ...

Mutations in the POU domain gene Brn-3c causes hearing impairment in both the human and mouse as a result of inner ear hair cell loss. We show here that during murine embryogenesis, Brn-3c is expressed in postmitotic cells committed to hair cell phenotype but not in mitotic progenitors in the inner ear sensory epithelium. In developing auditory and vestibular sensory epithelia of Brn-3c-/- mice...
