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...
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...
Cost-competitive with petroleum fuels Long-term stable price for budget forecasting Made from sustainable, renewable Biomass residuals Storable and pumpable liquid similar to petroleum fuels Clean burning fuel without the sulfur and particulates from petroleum fuels Low greenhouse gas emissions Sustainability issues have become an important part of the supply chain for operati...
/ 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...
1 Robert S. Thompson, Colorado School of Mines, Petroleum Engineering Department, Golden, CO 80401 [email protected] Abstract Peer and self-evaluations were conducted on interdependent multidisciplinary self-directed work teams. Teams worked on two projects during the semester with membership changing between the two projects. Generalizability theory was used to partition the peer ratings in...
The present paper is an attempt to assess the nexus between insurgency and underdevelopment in North East India. To achieve this end first various dimensions of insurgencies towards achievement of different goals in different states in the region are narrated. The impact of insurgency on infrastructure, industry including petroleum and tea, and environment are then analyzed. The origin and pers...
We investigated the possibility of re-using remediated soils for new bioremediation projects by spiking these soils with waste oil sludge in laboratory based microcosms. The level of Total Petroleum Hydrocarbon (TPH) reduction was high (>80%) in naturally attenuated microcosms and was not significantly improved by biostimulation, bioaugmentation and the combined treatment of bioaugmentation and...
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...
