Single breed fingerlings (12.0 ± 1.25 cm) of grass carp were obtained from a commercial fish seed hatchery recommended for good quality of fish seeds. Five treatments groups (T1-T5) in triplicate each containing 50 fingerlings of grass carp were maintained at 24 0.25°C, DO 7.18 ± 0.24 mg/l, pH 6.7 0.22 and hardness 140.7 3.8 mg/l in 90 liters of water in glass tanks. A zero dose treatment (T 1) was maintained as control. While other fingerlings were exposed to 5.0 µg/l (permissible) and 500 µg/l (sublethal) of waterborne cadmium (Cd) as treatment 2 and 3 respectively and 50 µg/l (permissible) and 1000 µg/l (sublethal) of waterborne lead (Pb) as treatment 4 and 5 respectively. Permissible (according to European Union standards for Cd and Pb in drinking water) and sub-lethal concentrations of Cd and Pb were prepared by dissolving cadmium chloride and lead acetate in deionized water. All fish were fed with pelleted green leaf feed (Cd, 0.05-0.08 µg/g and Pb, 0.08-0.11 µg/g dry weight) to an equivalent of 3 % wet body weight twice daily. Uneaten food and the feces were removed at 30 minutes after feeding from all tanks daily. It was observed that cadmium tiureatments caused significant (p<0.05) reduction in growth as compared to lead treatments and control group. The present studies has revealed that even very low concentrations (permissible) of heavy metals like Cd and Pb, that are considered as safe, do cause effects on growth of a freshwater fish meant for human consumption. It is therefore recommended to take particular precautionary measure to safeguard our water bodies from being contaminated with industrial effluents containing various heavy metal ions.

There were several trials to assess the posture deformities that may associated with scoliosis. The purpose: to investigate the correlation between Cobb's angle and three dimensional changes of the head, rib cage and pelvis in adolescent idiopathic scoliotic patients .Subjects: Thirty patients, their age ranged from (11-15 years) with a mean (12.63±1.326) years participated in this study. Method: Rotation around x,y,z axes, translation around x,z axes were measured by postureprint soft ware for head, rib cage, and pelvis regions and full spine radiograph were taken for every patients. Results: There was significant correlation between Cobb's angle and 3D head changes (P ≤ 0.05) except changes around translation z axis (p=0.979). There was significant correlation between Cobb's angle and 3D rib cage changes (P ≤ 0.05) except changes around rotation y axis (p=0.267). There was significant correlation between Cobb's angle and 3D pelvis changes (P ≤ 0.05) except changes around rotation y and z axes (p=0.668, 0.382). Conclusion: There is a correlation between Cobb's angle and 3D posture changes of head, rib cage, and pelvis.

The prohibition on the use of force in Article 2(4) of the United Nations Charter is subject to exemption by way of approval from the Security Council, or by invoking the right to self-defence. The use of force in self-defence is promulgated in Article 51 of the United Nations Charter, but is understood to be restricted by the principles of necessity and proportionality. Since the attacks in the United Stated on 11th September 2001, the law on self-defence has focused on the emergence of non-state actors within the framework of jus ad bellum. In view of this, and the contemporary context, this thesis seeks to reappraise the meaning of necessity in light of terrorism. In particular, the study asks whether the meaning of necessity is affected if self-defence is applied against a non-state actor, and if so, how. It also explores the establishment of the two conditions of self-defe...

The diagnosis of diffuse CNS infections depends on examination of cerebrospinal fluid (CSF) obtained by lumbar puncture (LP). The aim of this work was to determine the diagnostic value of CSF analysis in infants and children presenting with fever and convulsions. Methods: Detailed clinical data of infants and children included in this study were collected with special reference to the course and duration of the illness, description of the convulsions, consciousness level, signs of increased intracranial pressure, and signs of meningeal irritation. Lumbar puncture and chemical and bacteriological analyses of the obtained cerebrospinal fluid were done for all of the children. Results: The total number of children included in the study was 85, they had a median age 19 months, and 88% of them had generalized convulsions. CSF examination revealed that 20% had abnormal physical findings, while 23.5% had abnormal white blood cell count (WBC) (CSF Pleocytosis). CSF cultures were done in three cases with the highest White blood cells (WBCs), and streptococcus pneumoniae was present in all three cases. Conclusion: This study found that CNS infections are not uncommon in infants and children presenting with fever and convulsions in our locality, and acute bacterial meningitis cannot be excluded. However, its presence in the absence of clinical symptoms and signs of meningeal irritation is a remote possibility, but it should always be considered.
