Dietary Fibres Composition Analysis of Carob Seed Tegument as Locust Bean Gum Contaminants’ (Published)

The proximate composition and the fibres content of the carob seed tegument were analyzed in order to evaluate the effect of carob seed hull fragments (as contaminants) on locust bean gum (a galactomannan usually used as food additive) composition.The separation of the seed components by boiling water pre-treatment furnished ~30% of brown coat. The seed coat fibres analysis by enzymatic-gravimetric method with phosphate buffer showed that carob husk contain ~75% IDF (insoluble dietary fiber) and ~15% SDF (soluble dietary fiber). In addition, the NDF (neutral-detergent fibre) composition, determined by non-enzymatic-gravimetric method with detergent solution, revealed the presence of ~20% of insoluble hemicelluloses, ~33% of cellulose and ~9% of lignin fractions. These results suggest that this product may be regarded as a potential fibre source for Locust bean gum flour enrichment, and suitable for use as food ingredient.

Study Characterization of 〖Co〗_(0.3 ) 〖Zn〗_(0.7) 〖Fe〗_2 O_4 Nanoparticles by Co-Precipitation Method Within Two Techniques (Published)

The nanocrystalline  synthesized  by  the Co-precipitation method with two techniques based on different in initial molar concentration (pH suspension).The  structural and  magnetic  properties  of the  products  were  determined  and  characterized  in  detail  by  X-ray  diffraction  (XRD),  High Resolution -Transmission Electron Microscope (HR-TEM) , Fourier Transform Infrared (FTIR) and  vibrating  sample  magnetometer (VSM). The results suggest the grain size for first technique in the range of 6.14 : 13 nm and  second technique in the range of 8.8: 24.4 nm as the calcination temperature increases from 100 to 600°C respectively with different in initial molar concentration (pH suspension) for all techniques. X-ray analysis showed that the samples were  cubic  spinel structural ( kind  of  inverse  spinel  oxide).The crystallinity is improved with the  increases calcination temperature  for all techniques and that proved by the FT-IR  &  XRD results and compound  purity fabricated. HR-TEM analysis showed that nanoparticles size and the shape based on the initial molar concentration (pH suspension) & the calcination temperatures and also indicates that degree of agglomeration for all samples. VSM analysis showed that all the coercivity values were low enough to emphasize that the ferrite was a soft ferrite or super-paramagnetic behavior for most samples.

Human Resource Costs and Financial Performance: Evidence from Selected Listed Firms In Nigeria. (Published)

There is general lack of quantification and disclosure of human assets in domestic and international financial reports, and this appears to depress public assessment of the financial performance and value of firms. This study investigated the effect of human resource costs on the financial performance of firms in Nigerian.  The specific objective is to determine the extent to which investments in human resources influence profit after tax and turnover of firms in Nigeria. Secondary data on relevant financial variables were extracted from published financial statements of ten selected listed firms in Nigeria. The OLS technique was employed in analyzing the data and the results indicate that personnel benefit costs have positive and significant effect on Profitability, explaining about 73.9% of the variations in Profit After Tax of firms in Nigeria. The results however reveal no significant effect of Personnel Benefit Costs on firm turnover. The paper therefore concludes that investments in human resources have positive trade-off effects on profitability and growth of firms and recommends greater commitment to manpower development and training, while providing proper infrastructures and  conducive working environment to enhance the capacity of employees to drive positive improvements  in corporate financial performance.
