This study was conducted to evaluate the effects of bio-oil incorporation on properties of bio-oil-phenol formaldehyde (BPF) resol resins along with the optimization of petro-phenol substitution level. Crude bio-oil prepared from endocarp shells of Ziziphus mauritiana by direct solvolytic liquefaction (ethanol-water 1:1 wt./wt. at 300 °C) was used to partially substitute the petro-phenol (30% t...

Sarvak Formation as the oil reservoir with the most hydrocarbon potential in Yaran oil field is of special importance. The present research was conducted to study the reservoir parameters of this Formation. For this purpose, petro-physical crude data was first prepared and using the Geolog6.7 software, a petro physical plot was drawn. Afterward, petro-physical properties of reservoir were done ...

Integrated Fixed-Film/Activated Sludge (IFAS) technologies have been gaining wide popularity as an innovative and efficient treatment process for achieving nitrification in refining and petro-chemical wastewater treatment plants. IFAS technologies are sometimes referred to as Hybrid systems as the process combines the benefits of fixed film systems into the suspended growth activated sludge pro...

– The rapidly depleting conventional petroleum resources have promoted research for alternative fuels for internal combustion engines. Among various possible options, fuels derived from triglycerides (vegetable oils/animal fats) present promising ‘‘greener’’ substitutes for fossil fuels. Vegetable oils, due to their agricultural origin, are able to reduce net CO2 emissions to the atmosphere alo...

The paper approaches certain aspects regarding the involvement of the banking and industrial capital in the development and modernization of gold mining during the existence of „Mica” Company (1920-1948). The paper presents the political and economic factors contributing to the positive results in the field. It also provides examples of the way in which the banking and industrial capital was in...

The authors report an unusual location of a benign chondroma of the petro-sphenoidal synchondrosis extending into the cavernous sinus. Computerized tomography and magnetic resonance image features were characteristic of chondroid tumor. However, pathologic verification is mandatory in order to distinguish chondroma from chondroblastoma or chondroid chordoma.

Fossil fuels will always take command of human’s daily life. Despite being “dirty energy”, humans cannot jettison them since they are the mainstay for multipurpose energies. They more dependable and accessible than renewable energy sources such as hydropower, solar panel, wind power. Even so, in this present globalization increasing scale consumerism via digital technology social media consumes...
