Parasiticidal, antifungal and antibacterial activities of Onosma griffithii Vatke
Onosma griffithii was screened for possible pharmacological activities. The crude methanolic extract (MeOH) and its fractions demonstrated parasiticidal activity (IC 50 (Ƭg/ml Ā± S.D) = 31.03 Ā± 0.23) against Leishmania major. Based on the IC 50 values, the potency of the standard drug (Pentamidine) and test fractions were of the order as: Pentamidine > crude extract > n-hexane fraction > ethyl acetate (ETOAc) fraction > chloroform fraction (CHCl3) fraction > n-butanol (BUOH) fraction > aqueous fraction. Similarlymoderate antifungal activity was displayed by the crude methanolic extract against Aspergillus flavus and Fusarium solani. Against the Staphylococcus aureus, the aqueous fraction demonstrated moderate antibacterial activity
Breeding in bambara groundnut (Vigna subterranea (L.) Verdc.): strategic considerations
Bambara groundnut (Vigna subterranea (L.) Verdc.) has a large number of landraces throughout Africa where small-scale farmers have preserved its genetic diversity on-farm. To date, the full genetic diversity of the crop remains largely unexploited. Until recently bambara groundnut never received any appreciable research effort, especially for its genetic improvement. Until then, only selection breeding was practised in which existing landraces were evaluated and their seeds multiplied. However, no new combinations resulting from hybridisation had ever been produced. Recently, collaborative research efforts involving partners from Africa and Europe have produced the first crosses of bambara groundnut. The creation of these crosses is a significant scientific and practical achievement and opens up the possibility of breeding true varieties of this crop. This paper shows how different strategies have been combined to establish the basis of a strategic breeding programme in bambara groundnut. The paper also illustrates the use of landraces in the bambara groundnut breeding programme, as an example of the contribution that landraces can make to increasing productivity in marginal environments and the conservation of a crop's genetic resources on-farm.African Journal of Biotechnology Vol. 4 (6), pp. 463-471, 200
Development of Electronic Commerce Adoption Model based on Structural Equation Modeling Techniques
Advance Communication Technologies are playing a vital role in business today. In the world currently, many developing nations identified Small and Medium Scale organizations significantly important in counties2019; economic development. But the contribution from the SME sector is considerably low. Therefore, addressing this issue is important in business development. Among many reasons identified as barriers for SMEs to perform, studies have identified that low usage or not using technologies like E-commerce effected to this low performance. Therefore, studies are conducted to identify barriers to use technology in SMEs and many frameworks are tested and verified in different domains. In this study mainly tested and varied a framework which is considering Information Technological factors effecting the adoption of E-commerce technology and how it is effected for SME development. In this study framework is developed using literature analysis and hypothesis are developed based on past studies in terms of Information Technology factors as a main consideration. Model testing part is done using Structural Equation Molding using IBM AMOS. At the end of the study proposed framework is modified with statistical results and finally presented a framework which can be considered as a framework to understand the Information Technology factors effecting the E-commerce adoption and SME development
HUMAN CAPITAL PRACTICES IMPACT ON ORGANIZATIONAL PERFORMANCE
Human Capital is embedded in individuals with intelligence, expertise, knowledge, skills and education pronouncement made by many scholars. There are different phenomena explained by Context Generic Human Capital (HC) and Specific Human Capital. Those organizations that plan, organized and manage HC strategically gain high Organizational Performance than those who donāt. HC revolves as a vital factor to win business competition in contemporary firms. HC can be distinguished as āGeneral Human Capitalā and āSpecific Human Capitalā whereas General HC may be utilized across jobs, firms and industries however Specific HC may be utilized for particular job or in a specific firm etc. The effective management integrates human capabilities to gain valuable, rare and inimitable practices consequently lead to Organizational Performance. The study results recorded a positive significance of Human Capital Practices on Organizational Performance.Ā Article visualizations
An Approach to Screening for Resistance to Water and Heat Stress in Sorghum (Sorghum bicolor (L.) Moench)
Sorghum (Sorglttrm bicolor (L.) hlocnchl is an important food crop of thc arid and scmiarrd tropics
but average yields are s t i l l bclow 1.000 kilograms per hcctare. and under drought conditions these
may fall below 100 kilogranls per hectare or there may evcn be total crop failure.
Breeding for drought ,resistance in sorghum is a complex problem. Th e ohjec~ivco f thi s paper
is to drscribc the developnicnt of a screening technique. based on a "physiological approach." Itiitially.

Effects of planting density on water use and productivity of pearl millet (Pennisetum typhoides) grown on stored water. II. Water use, light interception and dry matter production
Pearl millet [Pennisetum americanum] was grown on stored water at Niamey, Niger, at row spacings of 38, 75 or 150 cm. Water extraction based on neutron probe readings was compared with crop transpiration using a porometer and allied measurements. Between 23 and 52 days after sowing, plants at the narrow and medium spacings used c. 77 and 100 mm of water, resp., and those at the wide spacing used between 59 and 75 mm. Estimates of seasonal crop evaporation from leaf resistances and from the green LAI of the crops were 103, 130 and 123 mm for the narrow, medium and wide spacings, resp. The water use/g dry wt. produced was similar for both narrow and medium spacings but water was used more efficiently in the wide spacing. Dry wt. increased in proportion to intercepted radiation with the same efficiency (1.3 g/MJ) irrespective of spacin
Response of four sorghum lines to mid-season drought. II. Leaf characteristics
Four sorghum lines were visually selected on the basis of degree of leaf disiccation for resistance and susceptibility to mid-season drought stress. An association between leaf-rolling and degree of resistance based on this method of selection had previously been observed, prompting this study to identify the physiological contribution of characteristics at the leaf level to mid-season drought resistance.
During the drought period, the resistant lines showed more leaf-rolling than the susceptible lines, reducing the effective area of the uppermost leaves by about 75%. Leaf-rolling in the resistant lines occurred over a very narrow range of leaf water-potentials (ā2.0 to ā2.2 MPa) compared to the susceptible lines. The strong correlation between the light-extinction coefficient k and leaf-rolling indicated that changes in k over the season were in part due to differing abilities of the lines to roll their leaves. However, expected differences in leaf temperature between lines due to radiation shedding were not found. Lines exhibiting leaf-rolling had higher leaf conductances, although transpiration rates per unit leaf area were similar. It is suggested that leaf-rolling may alter the leaf surface microclimate so that stomata may remain open and growth continue without associated high rates of water loss
Effects of planting density on water use and productivity of pearl millet (Pennisetum typhoides) grown on stored water. I. Growth of roots and shoots
Pearl millet [Pennisetum americanum] was grown on stored water at Niamey, Niger, at row spacings of 38, 75 or 150 cm to determine the physiological basis of exploitation and conservation of water by crops during drought. Between 18 and 32 days after sowing, roots grew rapidly beneath all crops, reaching 140 cm in the narrow spacing, but there were differences between crops in the pattern of growth. Soil cores and trench profiles indicated that plants in wider rows had fewer deeper roots. Substantial differences in both the amount and pattern of shoot growth were recorded in the different populations. Initially growth was fastest at the narrow spacing but stopped by day 45 and eventually the wide spacing produced most DM due mainly to greater survival of tillers. The partitioning of aboveground DM into vegetative and reproductive fractions was similar at all 3 spacings and was consistent with figures for comparable crops elsewhere. The important role of tillers is discussed in relation to the development and maintenance of a canop
