Abstract The use of medicinal plants for different therapeutic values is well documented in African continent. African diverse biodiversity hotspots provide a wide range of endemic species, which ensures a potential medicinal value. The feasible conservation approach and sustainable harvesting for the medicinal species remains a huge challenge. However, conservation approach through different biotechnological tools such as micropropagation, somatic embryogenesis, synthetic seed production, hairy root culture, molecular markers based study and cryopreservation of endemic African medicinal species is much crucial. In this review, an attempt has been made to provide different in vitro biotechnological approaches for the conservation of African medicinal… More >

Abstract The energy consumption in operation and maintenance stage of construction project accounts for 80% of the whole project life cycle and therefore research on influence factors of energy consumption in project operation and maintenance stage is of great practical significance. Based on data of 260 valid questionnaires in Jiangsu area, structural equation model is adopted in the Thesis for empirical research on influence factors in operation and maintenance stage. Based on theoretical analysis and factor analysis, the conceptual model and research hypothesis for influence factors of energy consumption in operation and maintenance stage are proposed to establish structural equation model… More >

Abstract Numerous models have been proposed in the literature to include phase change into numerical simulations of two-phase flows. This review paper presents the modeling options that have been taken in order to obtain a model for violent separated flows with application to sloshing wave impacts. A relaxation model based on linear non-equilibrium thermodynamics has been chosen to compute the rate of phase change. The integration in the system of partial differential equations is done through a non-conservative advection term. For each of these modelling choices, some alternative models from the literature are presented and discussed. The theoretical framework for all… More >

Abstract Occupational well-being is optimal psychological functioning and experience in the workplace. This study examined the role of opportunities for career development as a mechanism that links supervisor’s transformational leadership and subordinates’ occupational well-being manifested by work engagement. Specifically, drawing on conservation of resources theory (COR), we developed a dual pathway model in which opportunities for promotion and for professional development were posited as two important mediators in the relationship between transformational leadership and work engagement. The hypotheses were tested with a sample of 215 Chinese civil servants. The results of structural equation modeling showed that a supervisor’s transformational leadership was… More >

Abstract The aim of the present study was to investigate the efficiency of the encapsulation-dehydration technique for cryopreservation of Cyrtopodium hastchbachii Pabst seeds. Immature seeds of this species were cryopreserved by an encapsulation-dehydration technique. Seeds of five immature pods, 120 days after pollination, were encapsulated in 3% calcium alginate matrix and pretreated in liquid medium supplemented with 0.08 M sucrose (24 h), 0.15 M sucrose (24 h), 0.25 M sucrose (48 h), 0.5 M sucrose (24 h) and 0.75 M sucrose (24 h) in shaker at 60 rpm. Alginate beads were dehydrated 5 h in silicagel and immersed in liquid nitrogen… More >

Abstract Jubaea chilensis (Molina) Baill. (Chilean palm) is an endemic species in Chile. It has been classified as a vulnerable species because of the reduction and the fragmentation of its population numbers, the exploitation of the palms for the production of syrup, the indiscriminate harvest of seed for human consumption, and the reduction of the accompanying native vegetation cover. The southernmost limit of its natural distribution is located in Palmas de Tapihue (Pencahue, Maule region). The objective of this study was to benchmark the conservation status of this population and its accompanying vegetation. The population of J. chilensis in Tapihue was… More >

Abstract Sargodha district is one of the least studied regions of Pakistan regarding its ethnobotanical values. This paper is the first report related to the documentation and conservation status of the tree species in the Sargodha district, and their folk ethnobotanical uses. An interview base survey was conducted in the study area in 2010-2013. The ethnobotanical data revealed the use of 100 tree species (6 gymnosperms, 94 angiosperms) belonging to 77 genera (6 gymnosperms, 71 angiosperms) and 39 families (4 gymnosperms, 35 angiosperms), with the Fabaceae ranking first with 19 tree species, followed by the Moraceae (12 species). Tree species like… More >

Abstract Farmers’ role is important for the selection and conservation of the local diversity of native peppers (Capsicum annuum L.), which are distinguished by pod shape, plant traits, and show high levels of biogeographic and cultural heterogeneity. Our objective was to evaluate the phenotypic variation and postharvest changes of fruits in six morphotypes of native peppers from the Central Valleys of Oaxaca, Mexico. This would contribute information on the diversity of pepper landraces. Collection and characterization of plant and fruits were undertaken for 52 samples grouped into six morphotypes, under a completely randomized block design with three repetitions under greenhouse conditions.… More >

Abstract Two accessions of wild grapevines (Vitis spp.) native to Puebla State, Nealticán and Teziutlán, and other two native to Temascaltepec (1 and 2), Mexico State, were cultured in vitro using both Murashige-Skoog (MS) and woody plant medium (WPM) mediums. There were no differences between mediums for shoot generation. However, differences were shown among accessions for explant vigour, callus development, number of roots, leaves and nodes per explant. Rooting was evaluated only in MS medium by adding naphthalene acetic acid (NAA), indole butyric acid (IBA) or indole acetic acid (IAA) at 0.5 mg/L. With the exception of Temascaltepec 2, NAA generated… More >

Abstract The data collection approach called Participatory Rural Appraisal (PRA) was used in five villages: Killi Tor Shore; Medadzai; Ghunda; Kala Ragha, and Killi Shaban. Up to five groups were sampled in each village, comprising a total of 17 villages within the Zarghoon Juniper ecosystem. This area is rich both historically and culturally for using medicinal plants, mostly by women (60%). In this study, 26 species of medicinal plants fit in 20 genera and 13 families. They are used by aboriginal people via the indigenous knowledge they have for the treatment of many diseases. About 60, 35, and 5% of the… More >
