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,… 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 More >

Abstract Knowledge about the diversity patterns of vascular epiphytes and vines in the Valdivian rainforest of South America between 2000 and 2010 was systematized. The method was based on the review of publications available in four electronic databases using keywords. The results showed 12 studies conducted in Chile and two in Argentina, mostly in primary forests within protected areas. Research was carried out essentially at the habitat level, although there were one study at a landscape level and two reviews at a regional scale. The samples used came from ground-based observations and only two studies accessed… More >

Abstract Objectives: To evaluate the effect of zoledronic acid on androgen deprivation therapy in patients with hormone-sensitive prostate cancer by measuring the percentage change in lumbar-spine bone mineral density (BMD) at 12 and 24 months.
Materials and methods: An open-label, multicenter, randomized, two-phase study was conducted in patients with hormone-sensitive prostate cancer (N = 200) receiving 10.8 mg goserelin acetate with or without zoledronic acid (4 mg intravenously) every 3 months. In phase I, patients were randomized to goserelin acetate alone or goserelin acetate plus zoledronic acid for 12 months. In phase II, patients receiving goserelin acetate plus… More >

Abstract About 15% of the world surface is subjected to the effect of man activities. The main causes of land surface degradation are livestock production, deforestation and inadequate agricultural practices. In Mexico, little attention has been given to soil conservation as a non-renewable natural resource. This has been mainly degraded by excessive use of agricultural machinery. As a result, 64% of the national territory suffers some degree of deterioration. Comarca Lagunera, located between Coahuila and Durango states in Mexico, is the main milk production region. In this region, 900000 t of cow manure are produced annually.… More >

Abstract A finite element scheme based on the concept of TVD (total variation diminishing) with a flux-limiter for the hyperbolic systems of conservation laws is presented. The numerical flux is formulated effectively by the weighted integral form using exponential weighting functions. The TVD finite element scheme is applied to a Riemann problem, namely the shock-tube problem, for the Euler system of equations. Numerical results demonstrate the workability and the validity of the present approach through comparison with the exact solutions. More >

Abstract In this paper, a model is introduced to examine the evolution of the microstructure function under plastic deformations. This model is based upon a double continuity relationship that conserves both material particles in the mass space and orientations in the orientation space. An Eulerian description of the motion of material particles and orientations is considered, and continuity relations are derived for both spaces. To show how the proposed model works, two different case studies are provided. In the mass space, the continuity relation is used to examine the evolution of the microstructure function of a More >

Abstract An in vitro collection has been established with selected European aspen from Palencia province (Spain). Currently, this collection includes 32 high quality clones, selected for their good bearing and healthy state. Most of them belong to different discrete local populations.
Populus tremula L. was propagated in proliferation Aspen Culture Medium; they required subculture every 3 months. The purpose of this study was, therefore, to select a medium which allows the maintenance of 32 clones for a period longer than 3 months without subculture and to observe the behavior of those clones in 15 different culture medium compositions. Seven… More >

Abstract The dynamics of flexible systems, such as robot manipulators, mechanical chains or cables, is becoming increasingly important in engineering. The main question arising from the numerical modelling of large overall motions of multibody systems is an appropriate treatment for the large rotations. In the present work an alternative approach is proposed leading to a time-stepping numerical algorithm which achieves stable solutions combined with high precision. In particular, in order to check the performance of the proposed approach, two examples having preserved constants of the motion are presented. More >
