Sudden single-nucleon removal reactions from fast radioactive beams are now key to studies of the structure of rare isotopes. The sensitivity of the heavy residue's parallel momentum distribution to the orbital angular momentum of the removed nucleon is a crucial feature with a high spectroscopic value. Two-nucleon removal reactions provide experimental reach toward the rarest nuclear species. ...
Removal of foreign objects from the thoracic cavity could be performed by open or video-assisted surgeries. Anaesthesia for such cases demanding which would require one lung ventilation and intubation in unfamiliar positions. Depending on extent underlying injuries, sudden haemodynamic collapse should anticipated, precautions taken to manage occurrences. We present a unique case safely conducte...
Certain maternal mRNAs lose their poly(A) tails during early development and concomitantly become translationally inactive. In this report we analyze the mechanism of poly(A) removal during frog oocyte maturation by injecting short synthetic RNAs. We demonstrate that removal of poly(A) during oocyte maturation is a default reaction: In the absence of any specific sequence information, poly(A) i...
Hypoglycaemia may complicate removal of a phaeochromocytoma, but its pathogenesis is not well understood. The sixth such case in the world literature is reported together with details of glucose tolerance testing and hormone levels before and after extirpation of an adrenal phaeochromocytoma. The mechanism of hypoglycaemia probably relates to a sudden decrease in circulating catecholamines whic...
One hundred female Markhoz goats (42±5 kg) were used to investigate the ‘male effect’ on estrous synchronization and reproductive characteristics of female goat during the breeding season. This was carried out in three separate experiments. In the first experiment, forty female goats were used in 4 groups with different distance from the male goats (i.e. source of pheromone secretion); A1 (1 me...
Single nucleon pickup reactions were performed with a 18.1 MeV/nucleon (14)O beam on a deuterium target. Within the coupled reaction channel framework, the measured cross sections were compared to theoretical predictions and analyzed using both phenomenological and microscopic overlap functions. The missing strength due to correlations does not show significant dependence on the nucleon separat...
the aim of this paper is eliminating cr(vi) by natural hap. hap is a inexpensive material which is used from bovine critical bone ash in order to remove heavy metal ions like cr(vi). some experiments in different ph are performed (ph=2,3,7). maximum adsorption was appeared at ph=2, dosage=0.3 gr, c0=10 mg/l. cr(vi) removal depends on ph value and initial amount of cr(vi) result of experiments w...
Acute thrombosis of an abdominal aortic aneurysm is a rare but devastating surgical emergency. We present the first case of a patient with sudden thrombosis of an AAA delayed (more than 24 h) after removal of an intra-aortic balloon pump. Treatment options include open surgical repair, axillobifemoral grafting or endovascular aortic repair. The patient received an aorto-bifemoral graft. The ass...
