- "This research work investigated the modeling of Von Mises stress in LNG Spherical Carbon Steel Storage tank using assumed displacement Finite Element analysis based on shallow shell triangular elements. Using equations of elasticity, constant thickness carbon steel spherical storage tanks were subjected to different loading conditions. This paper stresses the need for proper definition of shallow element using sector angles to obtain the shallowness. The shallow spherical triangular element has five degrees of freedom at each of its corner node, which are the essential external degrees of freedom. The assumed displacement fields of these shallow triangular elements satisfied the exact requirement of rigid body modes of motion. The FORTRAN 90 programming language was used for the programme coding to solve finite element equations resulting from the model while Von Mises stresses distribution within the spherical storage tank shell subjected to different internal pressures were determined. The results showed that the use of non-shallow elements due to improper sector angles resulted in unreliable results while real shallow elements produced results that tallied with ASME Section VIII Div 1, Part UG values.

- A study was conducted to evaluate suya (tsire) an intermediate moisture meat product in Ogun State. Sixty suya sticks were used. Twelve suya sticks were prepared in the laboratory while 12 suya sticks were collected from each zone of the state namely: Yewa, Egba, Remo and Ijebu. They were analyzed for physical, chemical, microbiological and organoleptic characteristics. The results showed that there were significant (P < 0.05) differences in physical properties of suya samples analyzed with suya from Yewa zone having the highest (P < 0.05) water holding capacity and suya prepared in the laboratory and those from Egba zone had the highest (P < 0.05) shear force, while the pH was least (P < 0.05) in suya prepared from laboratory. Moisture content was least (P < 0.05) in suya samples prepared in the laboratory and from Egba zone, while ash content was higher (P < 0.05) in suya from Yewa, Remo and Ijebu Zones. Aerobic bacteria and coliform counts were least (P < 0.05) in suya prepared in the laboratory and from Egba Zone, while lactic acid bacteria were higher (P < 0.05) in suya prepared in the laboratory and from Egba Zone. The results revealed that suya samples prepared in the laboratory were accepted more (P < 0.05) followed by those from Egba and Remo Zones. However, microbial loads observed on Suya (tsire) samples in this study were not as high as those reported by previous workers. Nonetheless, efforts should be made to educate meat and meat products (Suya) processors in Ogun State on the importance of hygiene and proper packaging and preservation to avoid contamination and spoilage of meat products during processing and sale. 2 results 2
