The vegetation along the roads was disturbed and the erosion started immediately after the disturbance caused by the road construction. Our assumption is that biotechnical measurements should prevent the problems caused by erosion and improve stabilization of road edges. The knowledge of plant species which are able to grow in unfavourable conditions along the roads is important for correct selection of plants used for outplanting. The vegetation succession was observed using phytosociological relevés as a tool of recording and mapping assambblages of plants species along the roads as new linear structures in the landscape. Data from phytosociological relevés were analysed and the succession was characterised in different altitudes. The results can help us to select group of plants (especially shrubs and trees), which are suitable to be used as stabilizing green mantle in various site conditions and for different purposes (anti-erosional, ornamental, protection against noise or dust, etc.).

    The Access of Microenterprises to Commercial Microcredit in Aceh Besar: Closing the Gap Juanda1, Stefan Schwarze2, Stephan von Cramon-Taubadel3 1. Georg-August-Universität Göttingen, Tropical and International Agriculture, Germany; 2. Georg-August-Universität Göttingen, Department of Agricultural Economics and Rural Development, Germany; 3. Georg-August-Universität Göttingen, Department of Agricultural Economics and Rural Development, Germany Introduction . Reducing poverty has become an essential part of the Millennium Development Goals (MDG) and need to achieve. Microenterprises (MEs) have played an important role in rural developmental activities and were long recognized as vital in poverty alleviation in Indonesia. The developing world has in fact led the way in promoting the importance of rural finance. Access to commercial services is restricted in rural areas and the services can not meet the demand for financial services by rural households. Many microenterprises belong to poor and they are unable to provide collateral. Objectives Credit Limit There were two objectives formulated in this research: . In Indonesia, the official definition of microcredit covers all loans under IDR 50 million 1. To provide a review for the gap between the number of microenterprises (approximately US$5,500). being assisted and the overall number who might need assistance. Only seven percent of microenterprises have credit limit above IDR 50 million (Figure 4). 2. To determine effect of determinant factors which were found in research Figure 4.

  • A Review on the Phytochemistry and Pharmacology of Genus Tephrosia
    Phytopharmacology 2013, 4(3), 598-637 Touqeer et al. A Review on the Phytochemistry and Pharmacology of Genus Tephrosia Saad Touqeer1,*, Muhammad Asad Saeed1, Muhammad Ajaib2 1Department of Pharmacy, The University of Lahore, Lahore, Pakistan. 2Department of Botany, GC University, Lahore, Pakistan. *Corresponding author: [email protected]; Tel: +92-322-4899048 Received: 2 March 2013, Revised: 2 May 2013, Accepted: 9 May 2013 Abstract The plants of genus Tephrosia of family Leguminosae are widely distributed in many tropical and subtropical countries of the world and have been used in folk medicine for the treatment of large number of diseases. The importance of this gen- us is similar to that of other therapeutically renowned genera. This review includes the chemical studies on different species mainly the isolation and identification of flavonoids, rotenoids and study of activity of some isolated compounds and also includes diffe-rent pharmacological activities like antioxidant, antimicrobial, antic- ancer, antiplas-modial, anti-inflammatory, larvicidal and toxicity studies of extracts and fractions. Keywords: Tephrosia; Flavonoids; Rotenoids; Phytochemistry; Pharmacology; Acivity. Introduction Plants have been used for the treatment of diseases from centuries. Natural product chemistry, especially phytochemistry, has become a topic of interest for most of the research- hers due to the advantages of the plant derived medicinal compounds over the traditional ways of using herbal plants. Ethnopharmacology plays an important role in the discovery of new biologically active compounds. The process usually starts with searching of useful plants from different records to the development of methods for the industrial production of drugs (Rout et al., 2009; Farnsworth et al., 1985; Koehn and Carter, 2005).

    Cheruth et al. BMC Res Notes (2017) 10:61 DOI 10.1186/s13104-017-2388-0 BMC Research Notes SHORT REPORT Open Access Medicinally active principles analysis of Tephrosia apollinea (Delile) DC. growing in the United Arab Emirates Abdul J. Cheruth1*, Saif A. M. Al Baloushi1, Kandhan Karthishwaran1, Sajid Maqsood2, Shyam S. Kurup1 and Sabitha Sakkir3 Abstract Background: Tephrosia apollinea is a leguminous plant and is native to southwest Asia, Arabia, northwestern India and northeast Africa. In traditional system, it is used for medicinal and coloring purpose. The present study aims to explore the phytochemical, proximate analysis, element contents and antioxidant potential of T. apollinea extract. Methods: The phytochemical screening was done with qualitative methods. Proximate analysis and elemental composition were performed from powdered sample. In vitro antioxidant assays such as 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals and reducing power-scavenging assays were used for evaluating the antioxidant properties. Results: Qualitative screening of methanolic extract of T. apollinea showed the presence of alkaloids, phenolics, flavonoids, terpenoids, glycosides and saponins. The methanolic extract of T. apollinea exhibited a significant dose dependent inhibition of DPPH activity, with a 50% inhibition (IC50) at a concentration found to be 29.41 µg/ml, which was compared with standard GAE (IC50 31.09 μg/ml). The reducing power shows good linear relationship in both standard gallic acid (R2 0.956) and T. apollinea= extract (0.984). = Conclusions: The results of our study clearly suggested that the methanolic extract of T. apollinea may serve as potential source of natural antioxidant for nutraceutical application. Keywords: Phytochemical, Tephrosia apollinea, Proximate, Antioxidant, Free radical Background combating illnesses, including infectious diseases.

  • Urban Architecture for Sustaining Local Identity of Cultural Landscapes: a Study of Water Front Development in Khartoum, Sudan
    International Journal of Development and Sustainability Online ISSN: 2168-8662 – www.isdsnet.com/ijds Volume 4 Number 1 (2015): Pages 29-59 ISDS Article ID: IJDS14072701 Urban architecture for sustaining local identity of cultural landscapes: A study of water front development in Khartoum, Sudan Mohammad H. Refaat * Landscape Architecture Professor, Department of Urban Design Faculty of Urban & Regional Planning, Cairo University, Egypt Abstract Landscape is an indicator of common heritage as a combination of natural and cultural heritage. The of Landscape Architecture profession hosts several levels of intervention, starting from the planning level, the designing level, land suitability and water resources. This is done by applying scientific methods such as, ecological, economical, and social processes. Landscape is important as it provides the setting for our everyday lives. It is not only defined as a place of special interest nor does it refer solely to the countryside. It is the result of how people have interacted with the natural, social and cultural components of their environment and how they then perceive these. In recent years the land uses within the cities have been changing rapidly due to the various development pressures, and the tendency towards replacing all open spaces, public activities, and recreation areas to commercial and industrial uses has been enormous. The main objective of this research is to introduce an urban landscape design approach in dealing with cities waterfronts as a tool to enhance the overall sustainable the cultural landscape local identity within the urban structure of the city, taking the city of Khartoum, Sudan as a case study.
