USE OF SOME ETHNOMEDICINAL HERBS BY THE NATIVES OF SOLANG VALLEY, KULLU DISTRICT, HIMACHAL PRADESH
Authors: Kaur Maninder , Singhal Vijay Kumar , Singh Jaswant 
Published: September 2017

Objective: The objective of the study was to enlist the ethnobotanical uses of wild plants of Solang Valley, Kullu District, Himachal Pardesh. Due to the specific geographical location of the valley, it possesses a high amount of endemic plant diversity. The plants are being used medically by local people against many ailments such as rheumatism, gastric disorders, muscular pain, asthma, dysentery, diabetes, constipation, cold, cough, fever, etc.Methods: For documentation of ethnomedicinal information, a questionnaire containing vernacular name, plant part/s used, medicinal uses, method of preparation and amount of dose taken was prepared. To gather such information, personal interviews/interactions were conducted with medicine men (vaids and hakims), local healers, village elders, tribals and shepherds.Results: Presently, 42 plant species belonging to 41 genera and 24 families are included for ethnobotanical study with respect to their scientific names, vernacular names, plant parts used, ethnomedicinal purposes, mode of preparation, and dose/amount taken. As many as 23 species are used for treating more than one ailment. By consulting the previous literature, it was found that there are 19 species which have not been reported earlier and are used by the natives for different medicinal purposes.Conclusion: The unsustainable harvesting such as uprooting of whole plant of medicinal use from the wild is resulting into a serious decline in plant populations. Therefore various cultivation techniques should be designed, and implemented especially for the highly medicinally important and endangered plant species. Grazing should be restricted in high altitudinal zones possessing high endemic plant diversity. Further, information gathered on ethnobotanical aspects of plants of medicinal use will be helpful in the selection of elite genotypes/chemotypes which could provide a base for future plantation programmes which will be helpful for sustainable development of the valley.

John Ruskin e as pedras de Veneza
Authors: Amaral Claudio Silveira 
Published: September 2017

John Ruskin, crítico de arte inglês do século XIX, criou uma metodologia para o projeto de arquitetura com base em uma filosofia da Natureza, cuja ética é similar à de uma política da ajuda mútua, na qual cada elemento natural é dependente de outro na busca de uma situação de equilíbrio. Segundo essa lógica, Ruskin estruturou diversos temas, influenciando, com isso, intelectuais de sua época e de outras, como o escritor Marcel Proust, os arquitetos Frank Lloyd Wright e Le Corbusier, assim como o político intelectual brasileiro Rui Barbosa, que utilizou a lógica ruskiniana para compor sua Reforma do Ensino Primário, considerada o primeiro projeto de industrialização do Brasil. Ruskin, diferentemente do que atesta a historiografia da Arquitetura Moderna, foi um moderno e não um neogótico medievalista, pois seu trabalho se estruturou a partir de algumas das categorias da modernidade, como a lógica e a razão.PALAVRAS-CHAVE: Arquitetura. História. Metodologia.
Climatological significance of δ18 O in precipitation and ice cores: a case study at the head of the Ürümqi river, Tien Shan, China

Published: September 2017

AbstractStable-oxygen-isotope ratios (δ18O) of precipitation and ice-core samples collected from the headwaters of the Urümqi river, Tien Shan, China, were used to test the relationship between δ18O and contemporaneous surface air temperature (Ta). A strong temporal relationship is found between δ18O in precipitation and Ta, particularly for the monthly averages which remove synoptic-scale influences such as changes in condensation level, condensation temperature and moisture sources ( Yao and others, 1996). Linear fits as high as 0.95‰° C-1 for precipitation events and 1.23‰° C-1 for monthly averages are found. Although the δ18O amplitude in ice cores drilled at the nearby Ürümqi glacier No.1(~2 km from the precipitation sampling site) decreased dramatically compared to the precipitation samples, the ice-core records of annually averaged δ18 are still positively correlated with contemporaneous air temperature, especially summer air temperature, at the nearby Daxigou meteorological station. Nevertheless, the relationship between the ice-core δ18O records and contemporaneous air temperature is less significant than that for the precipitation samples due to depositional and post-depositional modification processes, which are highlighted by the successive snow-pit δ18O profiles from the Ürümqi glacier No.1. Our results might extend the application of high-altitude and subtropical ice-core δ18O —Ta records for paleoclimate reconstruction.
Slushflows at El Port del Comte, northeast Spain

Published: September 2017

AbstractSlushflows were first recorded in the Iberian Peninsula on 18 December 1997. Three slushflows were released at the ski resort of El Port del Comte, in the Catalan Pyrenees, northeast Spain, during intense rainfall. Two of the slushflows originated on the pistes, and the third affected another piste. Three ski lifts were damaged. This paper analyzes the hydrogeological characteristics of the massif, the geomorphic features of the terrain and the meteorological and snowpack conditions that caused the release of the slushflows. Man's role in triggering the slushflows by compacting snow on the pistes is also considered. Drainage control for reducing the hazard is outlined, taking into consideration the low frequency of the phenomenon.
Calculating dense-snow avalanche runout using a Voellmy-fluid model with active/passive longitudinal straining
Authors: Bartelt P. , Salm B. , Gruber U. 
Published: September 2017

AbstractA quasi-one-dimensional dense-snow avalanche model has been developed to predict avalanche runout and flow velocity in a general two-dimensional terrain. The model contains three different dense-snow-avalanche flow laws. These are: (1) a Voellmy-fluid flow law with longitudinal active/passive straining, (2) a Voellmy-fluid flow-law advanced by Russian researchers in which the Coulomb-like dry friction is limited by a yield stress, and (3) a modified Criminale—Ericksen—Filby fluid model proposed by Norwegian researchers. The application of the Voellmy-fluid law with active/passive straining to solve practical avalanche-dynamics problems is evaluated by applying the model to simulate laboratory experiments and field case-studies. The model is additionally evaluated by comparing simulation results using the Russian and Norwegian models. In a final analysis the influence of the initial conditions on avalanche runout is investigated. We conclude that the model resolves many of the shortcomings of the Voellmy–Salm model, which is traditionally used in Switzerland to predict avalanche runout. Furthermore, since the model contains the three well-calibrated parameters of the Swiss Guidelines on avalanche calculation it can be readily applied in practice. We discuss why we believe the Russian and Norwegian models are not ready for practical application. Finally, we show that many problems remain, such as the specification of the initial release conditions. We conclude that numerical models require a more detailed description of initial fracture conditions.
Water movement in the firn of Storglaciären, Sweden
Authors: Schneider Thomas 
Published: September 2017

AbstractThe hydraulic properties of the firn on Storglaciären, Sweden, were investigated in firn cores by water-table measurements and pumping tests. The mean density of the firn was 800 850 kg m3, giving an effective porosity of 0.073. The lower part of the firn layer was saturated with water, producing a maximum saturated layer of 5 m in late July. Hydraulic conductivity of the firn aquifer was determined from pumping tests to be 4.9 × 105 m s1. Percolation velocity, calculated from the time lag of maximal water input at the glacier surface and the water-level peaks, was 0.25 m h1. Percolation velocity increased over the ablation season, indicating a widening of the percolation pathways. A decrease in percolation velocity with percolation depth was found, reflecting decreasing permeability. The firn–water table responded to water input at the glacier surface with a delay of about 3 days. No diurnal variations were found in an area which was not influenced by fast drainage, indicating a diffusion of diurnal variations in meltwater production. One borehole intersected a water-filled cavity. Water level in this cavity showed diurnal variations, which probably were caused by diurnally produced meltwater waves moving fast through englacial conduits.
Interferometric radar observations of Glaciares Europa and Penguin, Hielo Patagónico Sur, Chile
Authors: Forster Richard R. , Rignot Eric , Isacks Bryan L. , Jezek Kenneth C. 
Published: September 2017

AbstractRepeat-pass L-band interferometric synthetic aperture radar (InSAR) data for part of Hielo Patagónico Sur, Chile, were collected by the space-shuttle-based Spaceborne Imaging Radar C (SIR-C) over a 4 day span in October 1994. Three co-registered complex SAR images are used to generate phase-coherence maps, a digital elevation model (DEM) and an ice-velocity map. The phase-coherence maps indicate low coherence in the 5–15 km approaching the termini due to large displacements, ice deformation and melting. However, the coherence is high over nearly all of the remaining imaged icefield. Ice-velocity precision is greater than 2 cm d−1, while the DEM is good to about 25 m. A flow divide between two of the glaciers is mapped by locating a narrow band of near-zero ice velocity. Horizontal ice-surface velocity profiles calculated along flowlines show there is a high degree of spatial variability reaching a peak value of 5.5 m d−1 located 3.5 km from the terminus of Glaciar Europa. Longitudinal strain rates along the center lines calculated from these velocities at the locations of the initiation of crevassing are used to compute the tensile strength of ice (169–224 kPa).
Meso- and microscale sea-ice motion in the East Siberian Sea as determined from ERS-1 SAR Data
Authors: Morris Kim , Li Shusun , Jeffries Martin 
Published: September 2017

AbstractSynthetic aperture radar- (SAR-)derived ice-motion vectors and SAR interferometry were used to study the sea-ice conditions in the region between the coast and 75° N (~ 560 km) in the East Siberian Sea in the vicinity of the Kolyma River. ERS-1 SAR data were acquired between 24 December 1993 and 30 March 1994 during the 3 day repeat Ice Phase of the satellite. The time series of the ice-motion vector fields revealed rapid (3 day) changes in the direction and displacement of the pack ice. Longer-term (≥ 1 month) trends also emerged which were related to changes in large-scale atmospheric circulation. On the basis of this time series, three sea-ice zones were identified: the near-shore, stationary-ice zone; a transitional-ice zone;and the pack-ice zone. Three 3 day interval and one 9 day interval interferometric sets (amplitude, correlation and phase diagrams) were generated for the end of December, the begining of February and mid-March. They revealed that the stationary-ice zone adjacent to the coast is in constant motion, primarily by lateral displacement, bending, tilting and rotation induced by atmospheric/oceanic forcing. The interferogram patterns change through time as the sea ice becomes thicker and a network of cracks becomes established in the ice cover. It was found that the major features in the interferograms were spatially correlated with sea-ice deformation features (cracks and ridges) and major discontinuities in ice thickness.
Ice-dynamic conditions across the grounding zone, Ekströmisen, East Antarctica
Authors: Mayer C. , Huybrechts P. 
Published: September 2017

AbstractA detailed investigation was performed of ice-dynamic conditions across the southern grounding zone of Ekströmisen, at the mouth of a regular East Antarctic outlet glacier not characterized by ice-streaming. Accurate field measurements along a profile 20 km long served as input in a two-dimensional numerical ice-flow model in order to calculate the variation of stress, strain rate and velocity with depth. The model results point to a sharp transition between the mechanics of grounded and floating ice, with a transition zone of only a few km between the two. Vertical shear, most of it near the base, was found to be the dominant flow mechanism in grounded ice. This part is also characterized by a distinct succession of surface undulations which are in turn controlled by variations in resistive stresses at the bottom. The associated phase shift between driving stress and basal drag was found to be accommodated by differential longitudinal pushes and pulls at the base. The flow in the upper half of the profile, on the other hand, is extensive everywhere. The adjacent ice shelf is characterized by small stress and velocity gradients in both the vertical and horizontal directions of the vertical section, and therefore has little deformation. A derived longitudinal deviatoric normal stress of only one-tenth of the value required for freely floating ice shelves reflects a large back-stress originating from friction along the side-walls of the narrow embayment.
Ice-core dating and chemistry by direct-current electrical conductivity

Published: September 2017

AbstractAlthough quantitative interpretation of the low-frequency electrical conductivity of ice cores from central Greenland is complicated by temperature variations of the measured core, annual layers can be recognized in sections of the core that are not impacted by non-seasonal features. Ambiguities in counting of annual layers can be minimized by comparing the electrical conductivity measurements to measurements of dust concentration and visual stratigraphy. A non-linear relationship between applied voltage and the current measured across two electrodes complicates the quantitative comparison of measurements made with different equipment, but does not affect the overall shape of the observed features.
Observations of the water-vein system in polycrystalline ice
Authors: Mader Heidy M. 
Published: September 2017

AbstractThe geometry of the vein system in ice has been investigated using photographs of enlarged veins in ice samples that were grown in the laboratory. The veins, which are non-uniform, act as tiny triangular-shaped, water-filled prisms that refract the light passing through them.The three vein widths in the cross-section of a vein can be deduced from two photographs taken from different directions. The dihedral angle along a given vein edge can be observed directly by viewing it at a node, where four veins meet, from a particular direction. The dihedral angles range from 25° ± 1° to 105° ± 1°. It is shown that the vein cross-section can be constructed, given the three widths of a vein and one of the dihedral angles, providing that the radius of curvature around the vein wallsrv is a constant. This assumption can be checked if the values of at least two of the dihedral angles associated with the vein cross-section are known. Ifrv is a constant, then the solid-liquid interfacial energy ϒsl must be isotropic for the veins in question and any deviations from uniform equilibrium geometry must derive primarily from anisotropy in the grain-boundary energy ϒss. The cross-sections of three veins that meet in a particular node are constructed. The assumption of isotropic ϒsl is found to hold for this node.
Seismic detection of transient changes beneath Black Rapids Glacier, Alaska, U.S.A.: II. Basal morphology and processes
Authors: Nolan Matt , Echelmeyer Keith 
Published: September 2017

AbstractUsing changes observed in daily seismic reflections, we have investigated the basal morphology of Black Rapids Glacier, Alaska, U.S.A. The englacial drainage of ice-marginal lakes caused significant changes in the daily reflections, as well as dramatic increases in basal motion. Changes in reflection arrival times and amplitudes indicate that there is a basal till layer at least 5 m thick at some locations beneath this surge-type glacier. Rapid changes in the observed reflection coefficients during the drainage events indicate that changes in till properties must occur throughout the entire 5 m thick layer, they must last for several days following the lake drainages and they must be completely reversible over as little as 36 min. Our seismic analysis shows that changes in effective pressure of the till are unlikely to cause the required changes in the reflection coefficients, but that a decrease in till saturation is likely. We therefore interpret the cause of the seismic anomalies as being a temporary decrease in saturation as water is input to the subglacial hydraulic system, and propose that such a change may occur quickly and reversibly by a redistribution of overburden pressure. Higher water pressures within the hydraulic system cause that region to support more of the glacier’s weight, leaving the remaining areas to support less. Any till within these areas of decreased normal stress would experience a consequent decrease in pore-water pressure, causing gas to exolve, thus decreasing saturation. This decrease in saturation would cause a change in the strength of the basal layer and may affect basal dynamics.
The role of lateral drag in the dynamics of Ice Stream B, Antarctica
Authors: Whillans I. M. , van der Veen C. J. 
Published: September 2017

AbstractThe partitioning of resistive force between the bed and sides of Ice Stream B, Antarctica, is obtained for three large areas that have been measured using repeat aerial photogrammetry. Problems associated with data errors and local variations in ice strength and velocity are reduced by considering the areally averaged budget of forces for each photo block. Results indicate that the bed under Ice Stream B must be very weak and unable to provide much resistance. Mechanical control on this ice stream emanates almost entirely from the lateral margins.
Flow and internal structure of a rock glacier
Authors: Elconin Roger F. , LaChapelle Edward R. 
Published: September 2017

AbstractExposure of a full transverse cross-section of the terminus of Fireweed rock glacier, Wrangell Mountains, Alaska, revealed a thin layer of unconsolidated debris mantling a consolidated mélange of ice and rock. The main rock glacier is fed by three tributaries; at the terminus, contacts between the three are sharply defined. Ice content is >50% by volume. Bubble foliation and crystal morphologies of the ice matrix are similar to those reported from glacier ice. Folded ice-rich strata and lenses, foliation planes, and the long-intermediate axial planes of tabular-shaped englacial clasts dip sleeply toward the center line of the rock glacier. The planar structures generally parallel the steep walls of the gorge containing the trunk stream. These steeply dipping, longitudinal structures appear to result from transverse compression where the tributaries converge and the trunk stream narrows down-valley.Bergschrund-like and moulin-like features at the heads of the middle and west tributaries, respectively, exposed admixed ice and rock similar to that of the terminus but lacking the well-developed flow texture. Talus from the unstable cirque headwall and polygenetic ice both accumulate at the base of the headwall and nourish the tributary rock glaciers.
