The journal welcomes all kind of research/review/abstract papers regarding Engineering subjects including Earth and Planetary Sciences, Environmental Science, Chemical Engineering, Agricultural and Biological Sciences, Renewable Energy, Biochemistry.
The characterization of in-situ formation water in oil reservoirs plays a critical role in the evaluation of the reservoir rock characteristics. The pH of the produced formation water that flows along with oil and gas infers the current wetting properties of the reservoir rock. The porous media belonging to part of the Tipam and Barail formations of the upper Assam basin are mostly water-wet sandstone rocks that often result in high water cut issues. This produced water, after collecting at surface installation and subsequent treatment in the effluent treatment plant, meets the criteria for in
Read MoreThis study was initiated with the aim of analyzing the acidity of rainfall in the humid savannah region of Lamto in a context of rainfall variability. With this in mind, our analysis was based on rainfall data supplied by SODEXAM and 1441 rainwater samples collected between 1 January 1995 and 31 December 2011 as part of the INDAAF network. The results show that about 85% of the rainwater collected is acidic. This proportion depends very little on the number of rainy days in a year. In addition, it can be seen that years with low rainfall have rainwater that is more acidic than years with high
Read MoreThe aim of this study is to synthesize new heterocyclic organic derivatives, where the process was carried out in several steps, in the first step Schiff bases compounds prepared from reaction of (1-aminonaphthalene) with aldehydes (salicylaldehyde and furfural) to prepare compounds A and B. The second step was the reaction of derivatives A and B with sodium azide, phthalic anhydride and thioglycolic acid to prepare derivatives of tetrazole (A1 and B1), oxazepine (A2 and B2) and thiazolidine (A3 and B3). All of the derivatives were characterized by FT-IR, 1H-NMR and 13C-NMR spectroscopy. The t

The present research examined 160 individuals, consisting of 112 men and 48 women (mean age 59.1 ± 8.4). The prescribed medication for each patient with type 2 diabetes mellitus was 500 mg of metformin per day. There are 80 participants in the healthy control group—64 male and 16 female (mean age 57.8 ± 8.9), all of them healthy who did not suffer from any kind of disease. This study found that there are
Read MoreThe paper presents experimental studies of hydraulic resistance and heat transfer in a tubular-lattice packing, which is a package of tubes with spiral turbulators. Smooth tubes and tubes with spiral turbulators made of M1 copper with a winding pitch of turbulators s/dэ=5,11-14,2 were used as experimental sections. Experiments on hydraulic resistance have established that with increasing flow velocity, the function Eu=f(Re) has a descending character both for smooth tubes and for tubes with turbulators in the entire range of Reynolds numbers Re=(0,02-30) 104. It has been revealed that with
