This paper is aimed at exploring the potential of implementing biomass as one of the sources of energy in Jordan using a simulated underground burial system. A controlled solar energy heated system was employed to maintain the anaerobic bioreactor at 40˚C (mesophilic range). Sludge and wastewater, from wastewater treatment plant, was used as a seed...

This study investigated the potential use of biochar produced from Iraqi date kernels (Khestawi) as an adsorbent for methylene blue (MB) removal from polluted water. A full factorial design methodology was employed to examine the effects of heating rate, pyrolysis temperature and holding time on the performance of the produced biochar. The results...

This study aims to assess the viability of utilizing poultry manure for biogas production as a means of contributing to the electricity grid and reducing environmental pollution in Jordan. A system consisting of a bioreactor, heating source, biogas collection device, and a subsystem for evaluating the ratio of biomethane to biogas is designed and f...

Currently, universities have rising demands to apply the incredible recent developments in computer technology that support students to achieve skills necessary for developing applied critical thinking in the contexts of online society. Medical and engineering subjects’ practical learning and education scenarios are crucial to attain a set of compe...

Abstract This study is planned to investigate the problems associated with the wasted sheep fleece in Jordan and to suggest methods to decrease its environmental impact. Results indicate that sheep fleece in Jordan makes an excellent resource for buildings insulation material. A linear regression model is used to predict sheep number for the period...

This study is designed to investigate the effect of electric charge associated with artificial surface on single platelet loss when known shear stress is applied. A capillary flow system is designed in a form of electric capacitor for the purpose of electric charge separation. Either positive or negative charge is applied to the walls of capillary...

Maintaining a temperature level of about 40°C, the optimum temperature for mesophilic bacteria’s growth and activity, is crucial for obtaining the best results with respect to biogas production. This study investigates the utilization of solar energy for heating a bioreactor that was already developed at our laboratory and is currently in operation...

This study involves an in-vitro experimental approach that was designed to investigate the possible interaction between liposome encapsulated hemoglobin (LEH). Reverse micelle processing was used to produce LEH. The study presented here does not indicate any negative interaction between LEH formed by reverse micelle method and relevant blood cells,...

Jordan is an example of a third world country that is non-oil producing but contains huge reserves of other energy sources such as tar sand, oil shale, and olive cake. Some limited research is available about how to utilize these energy sources in pure form. However, available research does not deal with combinations of these energy sources. This e...

In this study, an investigation of the potential of olive cake, which is available in large amounts in many developing countries and at very low cost, as a source of energy is conducted. The effect of olive cake grain size on its calorific value was studied. A process for intacting grains of olive cake in a suitable shape for handling, packaging an...

Electricity generation in Jordan is among the largest sectors of energy consumption of primary energy. The electricity audit at hand is a case study with the objective of identifying the major areas of electricity consumption of the different income groups of the population of Amman. The approach used in the case study can also be useful to other d...

Many countries which do not produce oil are rich with other sources of energy that are not fully utilized, such as tar sand, oil shale and olive cake. Limited previous work was done on producing carbonaceous matter and separating volatile matter from combinations of tar sand, oil shale and olive cake. In this study, a process is designed and tested...

The objective of this research is to study the waste heat recovery potential sources at the enclosed campus of Mu'tah University. Based on certain criteria, the kitchen of the students' club was identified as a good source of waste heat recovery. A coil heat exchanger was designed, manufactured, installed and analyzed to utilize the sensible heat c...

This study attempts to clarify the role of the artificial surface and the fluid bulk on platelet adhesion and aggregation events during simple shear flow of whole blood. The experimental approach involved the shearing of fresh whole blood samples over the shear rate range of 720-5680 s-1, which corresponded to a shear stress maximum of about 150 dy...

The effect of hirudin, a known inhibitor of thrombin, was evaluated for whole blood samples in terms of platelet deposition/adhesion to a non-biological test surface (tetrafluoroethylene-propylene copolymer), adenosine diphosphate (ADP) release and reduction in platelet count during laminar shear flow for a shear rate to 5680 s-1 (corresponding to...

• We evaluated the adherence of indium 111–radiolabeled endothelial cells to fibronectin-treated expanded polytetrafluoroethylene surfaces exposed to high (437 s−1) vs low (218 s−1) shear and the influence of shear on prostacyclin production. Canine jugular vein factor VIII–positive endothelial cells in passages 3 through 6 were incubated with111In...

Red blood cell (RBC) effects on platelet adhesion to a nonbiologic test surface (tetrafluoroethylene propylene copolymer) and platelet aggregation during laminar shear flow for shear rates to 5,680 s-1 (corresponding to shear stress to 200 dyne/cm2) were investigated. Results on hemoglobin (Hb) and adenosine diphosphate (ADP) release from RBCs, per...

Red blood cell (RBC) effects on platelet adhesion to a nonbiologic test surface (tetrafluoroethylene propylene copolymer) and platelet aggregation during laminar shear flow for shear rates to 5,680 s-1 (corresponding to shear stress to 200 dyne/cm2) were investigated.

Evidence has been accumulating which suggests that red blood cells affect platelet adhesion on nonbiological surfaces and platelet aggregation in the bulk; this in vitro study investigated these red blood cell effects. For samples of either whole blood or suspensions of either ghosts or red blood cells in platelet rich plasma undergoing low-stress...

The purpose of this in vitro study was to determine the effects of red blood cells (RBC) on platelet adhesion (PAD) and platelet aggregation (PAG) in low-stress shear flow, specifically: 1) the contribution of endogeneous adenosine diphosphate (ADP) release from RBC's as a result of shear-induced hemolysis to PAD and PAG; 2) whether phospholipids a...
