The Effect of Foreign Direct Investment on the Nigerian Manufacturing Sector
Opaluwa David,Ameh. A. Abu,Alabi J. O.,Abdul Mohammed
International Business and Management , 2012, DOI: 10.3968/j.ibm.1923842820120402.1075
Abstract: This study examined the effect of Foreign Direct Investment (FDI) on the Nigerian manufacturing sector spanning 1975 – 2008. Nigeria has embarked on several policy measures aimed at enhancing the manufacturing sector’s productivity coupled with the inflow of FDI to the country. The controversy is that the policy makers are not convinced that the potential benefits of FDI could be fully realized. The methodology adopted for the study is the Vector Auto Regression (VAR), co-integration and error correction techniques to establish the relationship between FDI and the growth of manufacturing sector. The findings from the study show that FDI has a negative effect on the manufacturing productivity and is statistically significant. Arising from the findings, it is recommended that government should create an enabling environment for foreign investment and the monitoring of FDI benefits, with particular focus of NEPAD and NEEDS through the instrumentality of the MDGs; thereby mustering the capacity for sustainable growth in the manufacturing sector. Key words: FDI; Manufacturing sector; Productivity; Growth, Policy
Effect of Human Menopausal Gonadotropin on Haematological and Serum Biochemical Parameters of Nigerian Indigenous Chickens
F.C. Iheukwuemere,A.H. Abu,M. Ameh
International Journal of Poultry Science , 2006,
Abstract: The present study was conducted to evaluate the haematological and serum biochemical parameters of Nigerian indigenous chickens. Twenty five healthy cocks were randomly assigned to five treatments consisting of intramuscularly administered 6.0, 12.0, 18.0, 12.0 I.U of Pergonal and sterile water (control). At the end of the three week experimental period, five birds from each group were bled weekly from the wing veins for haematology and serum biochemistry. Results of this study showed no significant differences (P > 0.05) in haematological parameters between the treatments. Serum total protein, albumin, urea and electrolytes differed significantly (P < 0.05) between the treatments. However, the values were within normal range, indicating that Pergonal had no deleterious effect on these parameters.

Open Journal of Stomatology (OJST) , 2014, DOI: 10.4236/ojst.2014.41007

The direct link between smoking, lung diseases, cancer, cardiovascular disease and poor pregnancy outcomes, such as miscarriage and low birth weight, has been extensively studied. In the past three decades, there has also been an increasing awareness of the impact of smoking on periodontal disease. Smoking is considered the major environmental risk factor in the prevalence, extent and severity of periodontal disease. This review article will attempt to build on previous studies in the periodontal literature in order to present an evidence-based comprehensive literature review on the effects of smoking on periodontal disease.

Open Journal of Stomatology (OJST) , 2014, DOI: 10.4236/ojst.2014.43022
Abstract: The positive relationship between smoking and major general health diseases such as cancer, cardiovascular disease, pulmonary disease and negative pregnancy outcomes is already established. Moreover, the association between smoking as a major environmental risk factor for periodontal disease has also been established. Smoking is considered to have negative adverse effect on periodontal therapy ranging from non-surgical treatment, periodontal surgery, regenerative procedures and implants. This review article will attempt to build on previous studies in the periodontal literature in order to present an evidence-based comprehensive literature review on the effects of smoking on periodontal therapy.
Fatal Spontaneous Haemothorax in a Child With Acute Leukaemia: A Case Report
L. B. Chirdan, E. A. Ameh
Nigerian Journal of Surgical Research , 2001,
Abstract: A 6-year old boy with acute leukaemia developed spontaneous bleeding and presented with spontaneous massive haemothorax. One litre of blood was drained at tube thoracostomy and another 300mls over the next 3 hours. The patient continued to deteriorate and died despite replacement of lost blood. The rarity of spontaneous haemothorax is highlighted and the importance of early diagnosis and treatment emphasised. (Nig J Surg Res 2001;3:34-36) KEY WORDS: Acute leukaemia, spontaneous haemothorax.
Pasteurellosis To Mannheimiosis: Taxanomic Changes
J Y Adamu, J A Ameh
Nigerian Veterinary Journal , 2007,
Abstract: Pasteurellosis is a disease of ruminants that have been recognized for long but there has been extensive reclassification of the aetiologic agent. Pasteurella haemolytica is the agent of pasteurellosis. Recent advances have renamed the organism to Mannheimia haemolytica conversely changing the disease name to Mannheimiosis. The bacterium has 17 serovars presently but serovars 3, 4, 10 and 15 retained the name Pasteurella which is predominantly associated with septicaemia while the rest are now known as Mannheimia. In Nigeria, serotypes A1, 2, 6, 7, 8, 9, 10, 11 and T10 has been reported. Therefore, pasteurellosis may well be called mannheimiosis.

Benedict A. Ameh, Dick I. Gernah, Okorie Obioha, George K. Ekuli
Food and Nutrition Sciences (FNS) , 2015, DOI: 10.4236/fns.2015.65055
Abstract: Pawpaw and lime juices were blended to produce mixed pawpaw/lime juice samples in the ratios of 90:10, 80:20, 70:30, 60:40 and 50:50) v/v giving samples A, B, C, D and E respectively. The moisture, mineral and vitamin contents, as well as the physical, microbiological and sensory qualities of the individual juices and blended samples were evaluated. While lime juice had higher moisture, calcium and vitamin C with values of 97.90%, 2.21 mg/100 g and 67.47 mg/100 g as compared to pawpaw juice with 92.96%, 1.53 mg/100 g and 35.49 mg/100 g respectively; the pawpaw juice had higher ash, phosphorus and vitamin A contents, with values of 3.12%, 54.97 mg/100 g and 5.90 IU/100 g as against 2.84%, 29.53% and 0.16% for lime juice respectively. While there was a general increase in moisture, calcium and vitamin C contents with blending, ash, phosphorus and vitamin A contents increased with increase in lime. The total solids content and specific gravity of pawpaw juice were remarkably higher at 7.04% and 1.15 g/m3 compared to 2.09% and 1.09 g/m3 respectively for lime juice. However, lime juice had a higher titratable acidity, while recording a lower pH of 2.89 as compared to 5.36 for pawpaw juice. The Total Viable Count (TVC) of lime juice was much lower (2.33 × 105 CFU/ml) than that of pawpaw juice (5.33 × 106 CFU/ml). There was significant difference (p < 0.05) in all the sensory parameters evaluated. Generally, there was an increase in the scores of each parameter from sample A to B and then a decline through to sample E. Sample B (80:20) mixed pawpaw/lime juice was most preferred, while sample E (50:50) was least preferred.
Improved Solid-Phase Peptide Synthesis of Wild-Type and Phosphorylated Phospholamban Using a Pseudoproline Dipeptide  [PDF]
Shadi Abu-Baker, Gary A. Lorigan
Open Journal of Synthesis Theory and Applications (OJSTA) , 2012, DOI: 10.4236/ojsta.2012.12002
Abstract: In this study, we report that the insertion of a pseudoproline dipeptide for the solid-phase peptide synthesis of wild-type Phospholamban protein (WT-PLB) has two important advantages. First, it disrupts the formation of different secondary structures, which is responsible for poor couplings during the preparation of highly aggregated sequences. Second, it enhances the purities and solubility of crude products leading to easier HPLC purification.
Solid-State NMR Spectroscopic Approaches to Investigate Dynamics, Secondary Structure and Topology of Membrane Proteins  [PDF]
Shadi Abu-Baker, Gary A. Lorigan
Open Journal of Biophysics (OJBIPHY) , 2012, DOI: 10.4236/ojbiphy.2012.24014
Abstract: Solid-state NMR spectroscopy is routinely used to determine the structural and dynamic properties of both membrane proteins and peptides in phospholipid bilayers [1-26]. From the perspective of the perpetuated lipids, 2H solid-state NMR spectroscopy can be used to probe the effect of embedded proteins on the order and dynamics of the acyl chains of phospholipid bilayers [8-13]. Moreover, 31P solid-state NMR spectroscopy can be used to investigate the interaction of peptides, proteins and drugs with phospholipid head groups [11-14]. The secondary structure of 13C = O site-specific isotopically labeled peptides or proteins inserted into lipid bilayers can be probed utilizing 13C CPMAS solid-state NMR spectroscopy [15-18]. Also, solid-state NMR spectroscopic studies can be utilized to ascertain pertinent informa- tion on the backbone and side-chain dynamics of 2H- and 15N-labeled proteins, respectively, in phospholipid bilayers [19-26]. Finally, specific 15N-labeled amide sites on a protein embedded inside oriented bilayers can be used to probe the alignment of the helices with respect to the bilayer normal [2]. A brief summary of all these solid-state NMR ap- proaches are provided in this minireview.
Inverse Nonnegativity of Tridiagonal M-Matrices under Diagonal Element-Wise Perturbation  [PDF]
Mohamed A. Ramadan, Mahmoud M. Abu Murad
Advances in Linear Algebra & Matrix Theory (ALAMT) , 2015, DOI: 10.4236/alamt.2015.52004
Abstract: One of the most important properties of M-matrices is element-wise non-negative of its inverse. In this paper, we consider element-wise perturbations of tridiagonal M-matrices and obtain bounds on the perturbations so that the non-negative inverse persists. The largest interval is given by which the diagonal entries of the inverse of tridiagonal M-matrices can be perturbed without losing the property of total nonnegativity. A numerical example is given to illustrate our findings.
