Nonlinear vibration analysis of dynamic response of carbon nanotube has created noble attention globally because of their properties and applications in tomorrow’s society. In this study, vibration of single-walled carbon nanotubes resting on elastic foundation with magnetic and thermal effects under the influence of Casimir force is presented.

The vibrations of carbon nanotubes under the influences of various internal and external forces have been subjects of interests for some years. These researches have not really considered the effects of surface energy and initial stress which are very important from both material and mechanical aspects of views. Therefore, the current study presents the simultaneous impacts of surface energy, initial stress and nonlocality and other various parameters on the nonlinear vibration of carbon nanotube hot fluid-conveying resting on elastic foundations in a magnetic environment. The derived equations governing the behaviours are solved using Galerkin’s decomposition-Adomian decomposition method is adopted to explore the concurrent impacts of surface elasticity, initial stress, residual surface tension and nonlocality on the nonlinear vibration of singlewalled carbon conveying nanotube resting on linear and nonlinear elastic foundation and operating in a thermo-magnetic environment

Adenoid cystic carcinoma (ACC) is a rare epithelial neoplasm, that may affect the salivary glands. It comprises 30% of epithelial minor salivary gland tumors. We present the case of a 56-year-old non-smoking woman with no significant medical history. The MRI finds a lesional process involving the right hemi mandible, the right buccal floor, which extends towards the region of the masticators and infiltrates the submandibular gland. A bone biopsy of the mandible under general anesthesia was performed, showing an adenoid cystic carcinoma. After announcing the diagnosis to the patient, she refused any treatment

Cerebral amyloid angiopathy (CAA) is frequently associated to Alzheimer’s disease (AD) but can also occur in Lewy body dementia (LBD). The present post-mortem study compares the incidence and the topographic distribution of small cerebrovascular lesions in LBD brains without and with severe CAA (LBD-CAA).

Temperature and size dependence magnetic moment of zigzag (n, 0) (n= 4, 6, 8, 10) copper oxide nanotubes (CuO NTs) have been computed by using a standard density functional theory. The computational work carried out by employing spin polarized generalized gradient approximation with revised Perdew Burke Ernzerhoff type parameterization along ab-initio approach. Bond length, binding energy and total magnetic moment have been analyzed and found that the bond length decreases at first and become saturated with increasing size of the nanotube.

Abdominal wall endometriosis is a rare condition occurring after caesarean section. A small painful nodule or lump near post caesarean scar is the common presentation. Large size endometrial nodules in anterior abdominal wall are uncommon and bleeding is very rare complication. In a thirty two years female a giant size endometrial nodule developed in a post caesarean scar. This patient presented as emergency during menstruation because of pain and lump with bluish discolouration. This case is reported for post caesarean scar large size endometriosis with extravasation of blood in surrounding anterior abdominal wall. This giant size endometriosis in anterior abdominal wall involving rectus abdominis muscle was successfully excised with a margin. The residual large size defect was repaired using polypropylene mesh.

Sickle cell disease (SCD) is the most frequent of a group of conditions known as haemoglobinopathies. The disease is an autosomal recessive genetic disorder, characterized by abnormal haemoglobin (Hemoglobin S) that under certain conditions polymerizes resulting in microvascular occlusions. This pictorial review illustrates the osteo-articular manifestations associated with sickle-cell disease encountered in children in our institution with at least one Haematology appointment in 2013/2014. Osteo-articular manifestations with imaging findings were reported in 28 out of 97 patients. The most frequent complications and those that required hospital care were painful vaso-occlusive crisis and femoral head osteomyelitis.

We report the case of a 52 year old man having no previous abdominal surgery who presented with small bowel obstruction. Computerised tomography showed mid jejunal obstruction, however, the cause of the obstruction could not be diagnosed radiologically. Laparotomy was performed and the obstruction was found to be due to a small annular jejunal tumour.

None of the known interaction models of electric and magnetic fields with the biological system can completely explain the effects which occur as a result of long-lasting exposure to electric and magnetic fields. We think that effects which cannot be explained by exposure to long-lasting, and albeit very low, electro-magnetic effects arise from molecular fatigue and the damage accumulation which occurs as a result of it.

Congenital dyserythropoietic anemia type III (CDA III) can be caused by mutation in KIF23. CDA III differs from CDA I and II in the sense that secondary hemochromatosis has not been reported. However, we have observed elevated serum ferritin in a CDA III family.
