TL;DR: Paying special attention to the medicinal plants found in the area through conservation may help to amplify their role in the healthcare system, poverty alleviation, and environmental protection.
Abstract: The objective of this study was to show the different ways medicinal herbs are used by the indigenous people in Port Harcourt metropolis (07 °3′ E, 04° 51′ N) in the Niger Delta region, Nigeria. One hundred and fifty structured questionnaires were administered, including oral interviews to herbal practitioners and users located at different parts of the city. Also, three popularly known herbal companies—Emiola naturalist care, Yem-Kem international herbal center, and Abiola medical herbal center—were included as they are healthcare providers, especially the medium income group. The results showed that a total of 83 plant species were recorded and classified according to their family, botanical, common, and local names. Also, the plant part used, mode of preparation, and type of ailment cured were included. The most frequently used plant parts were leaves followed by barks, roots, and fruits and with malaria fever as the most treated ailment. Deforestation, agricultural expansion, and fire were noted as the most important factors threatening the availability of these plants. The authors are of the opinion that paying special attention to the medicinal plants found in the area through conservation may help to amplify their role in the healthcare system, poverty alleviation, and environmental protection.

TL;DR: The time course of N2 fixation and N absorption was studied on Gliricidia sepium, Leucaena leucocephala, Albizia lebbeck in a screenhouse for 16 months using Senna siamea as a reference tree to determine how dependent a woody legume can be upon potential N sources.
Abstract: In order to determine how dependent a woody legume can be upon potential N sources, the time course of N2 fixation and N absorption was studied on Gliricidia sepium cv. ILG50, Leucaena leucocephala cv. K28, and Albizia lebbeck in a screenhouse for 16 months using Senna siamea as a reference tree. Dry matter and N yield in all four species increased steadily with time. The numbers and dry weight of nodules also increased with tree age. N-difference and 15N dilution methods correlated well (r = 0.87–0.93) in defining an increasing pattern of N2 fixation with time in all species, with the highest increment rate between sowing and 8 months. The percent N2 fixed ranged from 17.9 to 74%, 27.7 to 71.9% and 43.6 to 83.6%, equivalent to 191 to 3385 mg, 321 to 2863 mg and 533 to 6419 mg N in Leucaena, Gliricidia and Albizia, respectively, for the period between 4 and 16 months. In contrast to others, G. sepium had its peak of amount of N2 fixed at 12 months after planting. In both the proportion and amount...

TL;DR: In this paper, the mediating effect of intellectual capital on the relationship between board governance and perceived firm financial performance was examined, and the mediated model provided support for the hypothesis that intellectual capital mediates the relationship of board governance with perceived firm performance.
Abstract: Purpose – The purpose of this paper is to examine the mediating effect of intellectual capital on the relationship between board governance and perceived firm financial performance. Design/methodology/approach – This study was cross-sectional. Analyses were by SPSS and Analysis of Moment Structure on a sample of 128 firms. Findings – The mediated model provides support for the hypothesis that intellectual capital mediates the relationship between board governance and perceived firm performance. while the direct relationship between board governance and firm financial performance without the mediation effect of intellectual capital was found to be significant, this relationship becomes insignificant when mediation of intellectual capital is allowed. Thus, the entire effect does not only go through the main hypothesised predictor variable (board governance) but majorly also, through intellectual capital. Accordingly, the connection between board governance and firm financial performance is very much weakene...
