“…Because of the huge reserves and the large quantities that are annually mined, phosphate rock is considered a promising secondary source of uranium. The phosphate reserves in Egypt are assumed to be in the order of 700 million ton that would contain up to 40,000 ton of uranium at an average concentration of 60 ppm [1]. Most of the uranium contained in the phosphate rock is dissolved during its wet decomposition with the mixed acid solution composed of sulfuric acid and the recycled phosphoric acid (assaying 5% P2O5) to produce the wet process phosphoric acid (WPPA) and a calcium sulfate waste as a byproduct.…”

The chelating aminomethylphosphonic resin Amberlite IRC747 is used for uranium recovery from a synthetic phosphoric acid solution. The operating conditions of uranium extraction have been experimentally optimized by the batch technique viz., the phosphoric acid concentration, the contact time, the initial uranium concentration and the temperature. The effect of some interfering ions upon the effective capacity of the resin has also been examined. It has thus been found that the maximum uranium adsorption capacity of the studied chelating resin was found to attain 86.5 mg/g at 5 M phosphoric acid using 0.1 g resin for 120 min contact time with 50 mL acid assaying 200 mg U/L and room temperature. The obtained equilibrium data agreed well with the Langmuir isotherm model and the relevant thermodynamic parameters (ΔG, ΔH and ΔS) were evaluated and the uranium adsorption was found to be an endothermic reaction and of spontaneous nature. From the kinetic experiments it was shown that U(VI) adsorption followed the pseudo-second order kinetics model and the intraparticle diffusion model. Also, it has been possible to reveal from the kinetic and isotherm data the chemisorption nature of uranium on the Amberlite IRC747 resin. The adsorbed uranium ions can almost be completely eluted with 0.8 M (NH4)2CO3 solution from the loaded resin at room temperature. The studied optimized conditions have successfully been applied for uranium recovery from Abu Zaabal wet process phosphoric acid (WPPA).

“…In general, animal-related injuries should be analyzed based on the behavior and anatomy of the attacking animal. [1,2] Although rhinoceroses cause approximately 20% of human injuries, [3] and 30% of the human fatalities related to wildlife animal attacks, [4] very little is known about the mechanism of these injuries. There is only one case report in the literature describing this mechanism.…”

Animal-related injuries should be analyzed based on the behavior and anatomy of the attacking animal. Rhinoceros-related injuries in humans are extremely rare. Hereby, we report a life-threatening traumatic diaphragmatic hernia in a woman who presented three years after a rhinoceros gored her chest. A 47-year-old lady presented with abdominal pain, bilious vomiting and obstipation of one-day duration. She had recurrent attacks of colicky abdominal pain for a week before that. The patient gave the history of being admitted to the ICU three years before, after being gored by a rhinoceros into her chest while working as a veterinary assistant in the zoo. On examination, the abdomen was distended but soft and lax. Bowel sounds were exaggerated. Abdominal x-rays showed multiple air-fluid levels. A gastrographin follow through study hold up in the small bowel and did not reach the colon after seven hours. Abdominal and chest CT scan showed the splenic colonic flexure to be located in the left chest through a left diaphragmatic hernia. Urgent laparotomy showed a healthy splenic flexure of the colon that herniated through a 4 cm postero-lateral defect in the left diaphragm. The colon was reduced, and the defect was repaired with non-absorbable sutures. Postoperative recovery was smooth. The patient was discharged home 10 days after the surgery. Rhinoceros-related injuries in humans are extremely rare. Life-threatening traumatic diaphragmatic herniation may be delayed for few years. High index of suspicion is needed for its diagnosis.
