Optimal Design of FPSO Vessels

Abstract: The evaluation of principal dimensions of a Floating Production, Storage and Offloading (FPSO) system is one of the most critical tasks at the initial design stage of the vessel. It is therefore important to get this right from the onset. This paper presents a simple method of determining the optimal principal dimensions of FPSO vessels of any specified oil storage capacity. An Optimal Design Programme (OPTIMAP) has therefore been developed to analyze and compare the various responses of floating production vessels with the aim of selecting the best possible design to ensure not only a reduction in cost of construction, but also to maintain a safe operation and overall optimal performance of the vessel with regards to her dynamic responses in deep sea waves

Young lady with acral pustulosis and psoriatic arthritis

Abstract: Psoriasis is uncommon in this part of the world, and the pustular variety is even rarer. It is for this reason that the patients are frequently misdiagnosed by their health care providers and presentat late to the dermatologists when complications have already set in. We report a case of a 33 year old female who presented to us with a two year history of pustular eruptions on her hands and feet, pain and swelling of joints in the affected areas and subsequent development of deformities. Prior to her presentation, she has been misdiagnosed as having tuberculosis of the skin as well as leprosy in different hospitals and treated as such with no improvement. On presentation to us, a skin biopsy was done and the specimen sent for histopathology. A diagnosis of pustular psoriasis was made and she was placed on oral methotrexate. She responded to treatment and the lesions resolved in a few weeks except for the joint deformities. This case illustrates the challenges encountered by patients with psoriasis in a resource poor setting like ours as well as the importance of availability of affordable drugs like methotrexate in their management. This is so considering the high cost and non-availability of more modern biologic agents in this part of the world.

Anthropometric Relation of Neck and Waist Circumference in Overweight and Obese Nigerian Subjects: Implication for the Fashion Industry

Abstract: Introduction: In the local tailoring industries in Nigeria, it is generally assumed that the waist circumference is twice the neck circumference. Whether this is true for obese and overweight people is unknown. Objective: This study investigated the anthropometric relationship of the neck circumference to the waist circumference in overweight and obese people and its use in the clothing industry. Subjects and Methods: A sample size of 557 volunteers between 18 to 50 years was recruited for the study from the three campuses of the University of Port Harcourt. 391 were overweight (males=218, females=173) and 166 were obese (males=63, females=103). The neck and waist circumferences of volunteers were taken at the upper neck circumference (UNC), middle neck circumference (MNC), lower neck circumference (LNC) and upper waist circumference (UWC), middle waist circumference (MWC) and lower waist circumference (LWC) respectively. The Body Mass Index of the participants were determined after their weights and heights were measured to enable us categorize them into overweight and obese. The data obtained were analyzed with the aid of Microsoft Excel statistical tools. Results: Overweight males had UNC =37.83cm, UWC =83.69cm, MNC =37.72cm; MWC=85.79cm, LNC =38.43cm, LWC =86.37cm. Overweight females had UNC =33.64cm, UWC=78.02cm, MNC =33.64cm, MWC= 83.09cm, LNC =34.71cm, LWC=83.09cm. Obese males had UNC =40.15cm, UWC=93.87cm, MNC =40.12cm, MWC= 97.95cm, LNC =40.85cm, LWC =97.82cm. Obese females had UNC =35.07cm, UWC =90.86cm, MNC= 35.29cm, MWC =97.29cm, LNC =36.01cm, LWC =100.72cm. Pearson’s correlations(r) of the different regions of the neck and waist for overweight and obese subjects were determined. Conclusion: The correlation between the neck and waist circumference is weak in both overweight and obese. No subject has a waist circumference that is exactly twice the neck circumference. Estimation of waist circumference from the neck circumference will result in clothes that are not fitted.
