THE RESULTS OF THIS INVESTIGATION MAY BE SUMMARIZED AS FOLLOWS: 1. The inhalation of formaldehyde gas in even small quantities is followed by bronchitis and pneumonia. Pneumonia is due to the inhalation of the gas and not to secondary infection. 2. Formalin belongs to that rare group of poisons which are capable of producing death suddenly when swallowed. 3. The introduction of formalin into th...

The SAT solver RISS 2.0 and its concurrent parallelization PRISS 2.0 are described in the configuration they have been submitted to the SAT Challenge 2012. I. THE SEQUENTIAL SAT SOLVER RISS 2.0 Based on the CDCL procedure, this solver has been implemented as a module based system. The routines for the decision procedure, the learned clause management, unit propagation, preprocessor and the even...

A review of studies that have examined the integration of Web 2.0 tools into E-Learning 2.0 within built environment educational programs is undertaken. An analysis of studies undertaken reveals five core themes can be derived: (1) students using Web 2.0 demonstrate the capability for effective learning; (2) Skills learned via Web 2.0 can be transferred to the work and untrained tasks; (3) limi...

A theoretical analysis has been made of the van der Waals vibration-rotation-electron spin states of the 0 2-0 2 dimer in its 32 g "-32 g-electronic ground state. This analysis is based on a Hamiltonian that includes a spin-dependent 0 2-0 2 interaction potential and it involves also the permutation-inversion symmetry of the system. We have constructed some hindered internal rotor models for th...
