The CO 2 sequestration process includes capturing, separation and storage of carbon dioxide, and targets a potential solution mitigating the amount of CO 2 in the atmosphere. This work focuses on the last component of the aforementioned sequestration process, storage of CO 2 . Coal seams are chosen as potential repositories because there are several advantages where the sequestration costs can be offset in various ways.The purpose of this study is to develop a tool for the practicing engineer to predict the important performance indicators that are critical in CO 2 storage projects in coal seams. The neuro-simulation methodology coupling the hard computing protocols with the soft computing protocols is used. PSU-COALCOMP, a compositional coalbed methane reservoir simulator (hard computing protocol), is used to generate the necessary training data sets utilized in the training of the artificial neural networks (soft computing protocol) that are developed in this study. The tested neural network predictions are found to be accurate and sufficiently precise to establish confidence in the tool. Accordingly, the developed neural network can be used to screen thousands of possible scenarios of operational conditions in the optimization of the coal sequestration project design parameters in few seconds without going through intensive numerical simulations.

This study was investigated the wound healing effect of Anzer origin propolis specimens on rats' experimental intestinal incisions. Thirty-four male Wistar albino rats have been divided into five groups, weighing 250-300 gr. Water solution of Anzer propolis (PW3 [n=6], PW7 [n=6]) or ethanolic solution of Anzer propolis (PE3 [n=6], PE7 [n=6]) were administered. Control groups (K3 [n=5], K7 [n=5]) received no treatment. The surgical procedure (day 0) consisted of a laparotomy under general anesthesia, during which the colon was incised and repaired with sutures. The Anzer propolis specimen diluted with physiologic saline was administered by gavage (100 mg/kg/day) for 3 and 7 days before and after surgery to PW3 and PW7 groups. Ethanol dissolved Anzer propolis was administered by gavage (100 mg/kg/day) for 3 and 7 days before and after surgery to PE3 and PE7. Experimental animals have been humanly euthanized on the 3rd and 7th days for biochemical and histopathological evaluations. ELISA has measured the serum total oxidant status, total antioxidant status, interleukin-1, interleukin-6, tumor necrosis factor-alpha, myeloperoxidase, hydroxyproline, nitric oxide, and antioxidant activity. The incision line sampled to evaluate inflammatory cells, fibroblastic activity, neovascularization, and collagen level. The study indicates that the ethanolic Anzer propolis solution's oral administration has a beneficial effect on intestinal wound healing for seven days pre-and postoperatively (PE7).
