The purpose of this study was to propose a conceptual model for technology transfer (TT) that houses several factors. These factors are believed to influence the processes’ effectiveness and guide the TT performance. In addition, this study aimed to explore TT performance and the relationship between TT government support, infrastructure, TT environment, and TT learning capability. Oil producti...

Our understanding of fuel oxidation has improved with rigorous experimental and theoretical investigations being performed in recent years. As investigation methods evolve, our fundamental chemistry advances. This process allows us to revisit improve existing chemical kinetic models. Propane propene have been studied various facilities at different conditions; however, the interaction these two...

In the present study, the petroleum ether and alcoholic extract of Morinda citrifolia L. (Noni) leaves were subjected to preliminary screening for antimicrobial and anthelmintic activity. The alcoholic extract exhibited significant anti bacterial, antifungal activity, comparable to the standard drug tetracycline. The petroleum ether and alcoholic extract were evaluated for Anthelmintic activity...

/ Petroleum asphaltenes are defined as the n-pentane or n-heptane insoluble but toluene soluble fraction of crude oils or petroleum residua. This operational definition is a consequence of the extremely complex structure of asphaltenes which consist of thousands of compounds containing highly aromatic cores, long chain aliphatic groups, heteroatoms (sulfur, nitrogen, and oxygen) as well as trac...

the most usual type of petroleum mulch, which has been successfully used to combat desertification in large areain iran for more than thirty years, is produced by heavy residue petroleum cuts. the petroleum mulch consists of awide range of different heavy hydrocarbons such as polycyclic aromatic hydrocarbons (pahs). pahs are present atlow level in petroleum mulch, where there is contact with wa...

Recent advances in interdisciplinary fields as diverse as astrophysics, cosmogeophysics, nuclear geology, etc. have led to interesting developments in the non-organic theory of the genesis of petroleum. This theory, which holds that petroleum is of an abiogenic primordial origin, provides an explanation for certain features of petroleum geology that are hard to explain within the standard organ...

The middle Cretaceous Colorado Group of the Western Canadian Sedimentary Basin consists predominantly of mudstone deposited during major marine inundations interspersed with relatively thin sandstone and conglomerate beds. The Colorado Group petroleum system, containing a large portion of the light-medium oil and natural gas reserves within the Middle Jurassic to Cretaceous foreland basin succe...

Soils are arguably the most microbially diverse ecosystems. Physicochemical properties have been associated with the maintenance of this diversity. Yet, the role of microbial substrate specialization is largely unexplored since substrate utilization studies have focused on simple substrates, not the complex mixtures representative of the soil environment. Here we examine the exometabolite compo...
