Inter-district variation of development in Southern region

SUMMARY The level of development of different districts of the States of Andhra Pradesh, Kamataka, Kerala and Tamil Nadu belonging to the Southern Region of the country was obtained with the help of composite index based on an optimum combination of thirty economic indicators. Seventy eight districts of the southern region were included in the analysis. The data on the economic indicators for the year 1991-92 have been used in the study. The district of Thrissur from Kerala ranked first and the district of Bidar (Kamataka) was ranked last in the level of socio-economic development. Among the most ten advanced developed districts of the southern region. seven districts come from the State of Kerala, two districts belong to Andhra Pradesh and one district comes from Tamil Nadu. Similarly among the ten most backward districts of the region, six districts come from Andhra Pradesh, two districts belong to Karnataka and remaining two districts are from Kerala. In case of agricultural development, the district of Shimoga from Kamataka ranked first and the district Nilgiris from Tamil Nadu ranked last. Four districts from Andhra Pradesh and six districts from Karnataka are found to be the best ten agriculturally advanced districts of the southern region. Wide disparities have been observed in the level of development among different districts of the region. The development of education from primary level onwards is found to be an urgent social need in some of the districts as their literacy level is below 45 per cent as compared to 52 per cent at All India level. Some of the districts require a unified balanced integration of curative, preventive and promotional health services.
Estimation of frequency dependent coda wave attenuation structure at the vicinity of Cairo Metropolitan Area

Estimation of seismic wave attenuation in the shallow crust in terms of coda wave Q structure previously investigated in the vicinity of Cairo Metropolitan Area was improved using seismograms of local earthquakes recorded by the Egyptian National Seismic Network. The seismic wave attenuation was measured from the time decay of coda wave amplitudes on narrow bandpass filtered seismograms based on the single scattering theory. The frequency bands of interest are from 1.5 to 18 Hz. In general, the values obtained for various events recorded at El-Fayoum and Wadi Hagul stations are very similar for all frequency bands. A regional attenuation law Qc = 85.66 f0.79 was obtained.
Influence of the form of copper in the friction material of disc brakes on the coefficient of friction and wear in rig tests

More than 15 components occur in the friction materials for disc brake pads. Copper in the form of powder or fibres is counted among reinforcers and it plays an important role in the braking process. The brake pads tested, reinforced with a 2% admixture (by weight) of copper powder or fibres, were manufactured in a normal production process at the TOMEX Company. The tests were carried out on a T-11 (“pin-ondisc”) test machine for small specimens prepared from the friction material under consideration and on a Kraus test machine, where finished brake pads were examined. The test conditions were close to the normal brake operation conditions. The brake discs used as counter-specimens were made of grey cast iron with flake graphite.
An organisational change approach to implementing IT service management

Although an increasing number of organisations implement the IT Infrastructure Library (ITIL) with the aim to improve Information Technology (IT) services to their customers, a significant number of ITIL implementations do not achieve the expected outcomes. Enterprise Resource Planning (ERP) and Business Process Reengineering (BPR) projects have similarities with ITIL implementations. ERP and BPR researchers using a socio-technical work systems lens have identified that using a formal change management strategy incorporating a socio-technical approach can assist in implementation success. The proposed explanatory research described in this paper seeks to identify if using a socio-technical approach to organisational change can influence the success of ITIL implementations. This paper presents the preliminary findings based on two case studies and provides a detailed view of the strategies and actions of organisations implementing ITIL. This research aims to contribute to practice and research by establishing a model for effective strategies for ITIL implementation.
Do Gardens Make You Green?: Home Gardens, Identity, and Pro-Environmental Behavior Among Southeast Asian American UC Berkeley Students

Pro-environmental behavior comprises actions that are intended to be beneficial to or relatively unharmful to the environment, and may be influenced by intersecting forms of ethnic identity and environmental identity. Ethnic identity is one’s perceived connection to a particular ethnic group(s), and environmental identity is one’s perceived connection to the natural world. There is no research on the relationship between these forms of identity. To examine this relationship I surveyed second-generation Southeast Asian American UC Berkeley students, eliciting information about their experiences with home gardens, their connection to ethnic identity and their environmental identity. The study objectives considered: 1) the overlap between environmental and ethnic identity, 2) the relationship between environmental identity, ethnic identity and pro-environmental behavior, and 3) home gardening influences on identity and pro-environmental behavior. I found statistically significant correlations between environmental identity and proenvironmental behavior, which was expected and supported in other studies. I also found significant correlations between environmental identity and ethnic identity, and increased pro-environmental behavior with home-gardening exposure. Home gardens are able to lay the foundation for an enhanced ethnic connection while providing exposure to green areas and promoting pro-environmental behavior.
BDÁFRICA: diseño e implementación de una base de datos de la literatura poscolonial africana publicada en España

espanolRESUMEN: Este trabajo demuestra que no existe un repositorio que incluya los autores poscoloniales africanos publicados hasta el momento en Espana y que permita, por ende, realizar estudios cuantitativos y cualitativos del impacto de esta literatura con la precision deseable. Esto supone una carencia tanto para investigaciones academicas como para el sector editorial a la hora de analizar tendencias de seleccion y recepcion en el mercado. Ante esta situacion, el objetivo primordial de este trabajo es disenar e implementar una base de datos, basada en MySQL y delimitada por unos parametros muy concretos, que recoja todas las obras de autores africanos publicadas en castellano en Espana entre 1972 (ano en que Espana se unio al sistema ISBN) y 2014. Tras determinar unos criterios de diseno y unos protocolos de compilacion especificos, el desarrollo metodologico se ha dividido en cuatro fases: recopilacion, almacenamiento, tratamiento y difusion de los datos. Asi, la base de datos BDAFRICA consigue un doble objetivo: por un lado, proporciona a los investigadores datos fiables en los que basar sus estudios y, por otro, permitiria ofrecer por primera vez datos estadisticos de la evolucion de la publicacion de obras de autores africanos en Espana en los ultimos 42 anos. EnglishABSTRACT: This paper evidences the absence of a repository or database that scompiles the publications of Postcolonial African writing in Spain, thus precluding comprehensive quantitative or qualitative studies on the impact of these works. This is a significant obstacle for both academic research and the book market, which up to now has been unable to analyse market selection and reception trends. To cater for this need, the aim of this paper is to describe the design and implementation of a relational database, based on MySQL and set up using specific and accurate parameters, that includes all the literary works penned by African writers and published in Spain and in Spanish from 1972 (when Spain first joined the ISBN system) to 2014. After determining a number of specific design criteria and compilation protocols, the methodology has been divided into four steps: data collection, storage, statistical processing and online dissemination. Thus, the database BDAFRICA achieves a twofold objective: firstly, it provides researchers with unbiased data as a framework for their studies, and secondly, it offers unprecedented statistics on the evolution of the publication of African literature in Spain over the last 42 years.
Land cover change detection in West Jilin using ETM ＋ images

In order to assess the information content and accuracy ofLandsat ETM+ digital images in land cover change detection,change-detection techniques of image differencing,normalized difference vegetation index,principal components analysis and tasseled-cap transformation were applied to yield 13 images. These images were thresholded into change and no change areas. The thresholded images were then checked in terms of various accuracies. The experiment results show that kappa coefficients of the 13 images range from 48.05 ～78.09. Different images do detect different types of changes. Images associated with changes in the near-infrared-reflectance or greenness detects crop-type changes and changes between vegetative and non-vegetative features. A unique means of using only Landsat imagery without reference data for the assessment of change in arid land are presented. Images of 12th June, 2000 and 2nd June, 2002 are used to validate the means. Analyses of standard accuracy and spatial agreement are performed to compare the new images (hereafter called "change images" ) representing the change between the two dates. Spatial agreement evaluates the conformity in the classified "change pixels" and "no-change pixels" at the same location on different change images and comprehensively examines the different techniques. This method would enable authorities to monitor land degradation efficiently and accurately.
Characterization of electromagnetically-induced-transparency-based continuous-variable quantum memories

One of the steps toward the realization of quantum computation is a device that allows the coherent storage of information. The Heisenberg uncertainty principle HUP sets a limit on the quality of stored information that depends on direct measurement and subsequent reconstruction. Much experimental and theoretical research is directed toward quantum memories for light to circumvent this classical benchmark. To realize such memories, methods that provide a coherent interface between large atomic ensembles and light fields have been proposed.
An experimental and numerical study of polymer action on relative permeability and capillary pressure

Unsteady state two-phase flow experiments were performed to check the action of an adsorbed water-soluble polymer on relative permeability and capillary pressure. A selective reduction of the relative permeability to water with respect to relative permeability to oil was observed. Capillary pressure, measured directly on the core, was increased after polymer injection. Since the polymer has little influence on interfacial tension, this trend is interpreted as a reduction of pore size due to polymer adsorption. The validity of this assumption was checked by the investigation of a pore-scale numerical model. Relative permeabilities and capillary pressure were computed for a range of flow rates. Numerical results indicated that the polymer adsorption model (wall effect) successfully reproduces qualitatively the experimental observations.
Application of DSSAT model to simulated thermophilic crops in central and southern Europe

This study presents applications of DSSAT version 4.5 software package to simulate thermophilic crops. The results are used to identified adaptation options to reduce impacts of climate changes, pest and diseases in thermophilic crops in the central and south-eastern Europe, specifically in Elbe River lowland and Romania. For the Czech Republic, experimental research at farm level includes: (1) testing thermophilic assortment of vegetables in Elbe lowland conditions; (2) monitoring the meteorological data, phenological phases, soil characteristics, leaf area and the amount of aboveground biomass on farmer vegetable fields. For Romania, the focus is put on crop water use efficiency under current and future climate scenarios for thermophilic species (maize) in different agricultural sites from south and south-eastern regions. CERES Maize and CROPGRO-vegetables modules embedded in DSSAT were used.
Hydrology and Hydrological Modelling of Acidic Mires in Central France

This thesis identifies, quantifies and models water fluxes within the Dauges National Nature Reserve, an acidic valley mire in the French Massif Central. A range of techniques were used to investigate the nature and geometry of granite weathering formations and of peat deposits. Rainfall, reference evapotranspiration, stream discharge, stream stage, groundwater table depths and piezometric heads were monitored over a three-year period. The distributed, physics-based hydrological model MIKE SHE / MIKE 11 was used to model water flow within the mire and its catchment. It was shown that the mire is mostly fed by groundwater flowing within the densely fissured granite zone and upwelling through the peat deposits. Upwelling to the peat layer and seepage to overland flow were highest along the mire boundaries. However hydrological functioning differs from this general conceptual model in some locations due to the high variability of the peat hydraulic characteristics, the presence of highly permeable alluvial deposits or past human interference including drainage. The equivalent porous medium approach used to model groundwater flow within the fissured granite zone gave satisfactory results: the model was able to reproduce discharge at several locations within the high-relief catchment and groundwater table depth in most monitoring points. Sensitivity analyses showed that the specific yield and horizontal hydraulic conductivity of the fissured zone are the parameters to which simulated stream discharge and groundwater table depth, including in peat, are most sensitive. The model was forced with new vegetation parameters to assess the potential impacts of changes in catchment landuse on the mire hydrological conditions. Replacement of the broadleaf woodlands that currently cover most of the catchment with conifer plantations would lead to a substantial reduction in surface and groundwater inflows to the mire and to a substantial drop in summer groundwater table depths, particularly along the mire margins.
High-Pressure in Situ 129Xe NMR Spectroscopy: Insights into Switching Mechanisms of Flexible Metal–Organic Frameworks Isoreticular to DUT-49

Flexible metal–organic frameworks (MOFs) are capable of changing their crystal structure as a function of external stimuli such as pressure, temperature, and type of adsorbed guest species. DUT-49 is the first MOF exhibiting structural transitions accompanied by the counterintuitive phenomenon of negative gas adsorption. Here, we present high-pressure in situ 129Xe NMR spectroscopic studies of a novel isoreticular MOF family based on DUT-49. These porous materials differ only in the length of their organic linkers causing changes in pore size and elasticity. The series encompasses both, purely microporous materials as well as materials with both micropores and small mesopores. The chemical shift of the adsorbed xenon depends on xenon–wall interactions and thus on the pore size of the material. The xenon adsorption behavior of different MOFs can be observed over the whole range of relative pressure. Chemical shift adsorption/desorption isotherms closely resembling the conventional, uptake-measurement-based isotherms were obtained at 237 K where all materials are rigid. The comparable chemical environment of the adsorbed xenon in these isoreticular MOFs allows to establish a correlation between the chemical shift at a relative pressure of p/p0 = 1.0 and the mean pore diameter. Furthermore, the xenon adsorption behavior of MOFs is studied also at 200 K. Here, structural flexibility is found for DUT-50, a material with an even longer linker than that of the previously known DUT-49. Its structural transitions are monitored by 129Xe NMR spectroscopy. This compound is the second known MOF showing the phenomenon of negative gas adsorption. Further increase in the linker length results in DUT-151, a material with an interpenetrated network topology. In situ 129Xe NMR spectroscopy proves that this material exhibits another type of flexibility compared to DUT-49 and DUT-50. Further surprising observations are made for DUT-46. Volumetric xenon adsorption measurements show that this nonflexible microporous material does not exhibit any hysteresis. In contrast, the in situ 129Xe NMR spectroscopically detected xenon chemical shift isotherms exhibit a hysteresis even after longer equilibration times than in the volumetric experiments. This indicates kinetically hindered redistribution processes and long-lived metastable states of adsorbed xenon within the MOF persisting at the time scale of hours or longer.
Rain Variability and Population Growth to Explain Historical Levels of the Patzcuaro Lake in Mexico

The height variability of Lake Patzcuaro, in central Mexico, remained constant for several decades, and during that period, the lake maintained its functionality and environmental services. However, in the last twenty years, there has been a significant decrease in the variability range. In order to estimate the water balance, in this work, an approach was developed to understand how water moves in time and space, and to determine possible inherent thresholds to lake variability. The historical Lake Patzcuaro height above 2035 masl was correlated with several climatic variables. The correlation with monthly rainfall shows that there is a delay of three months, indicating that the lake volume depends on three factors: precipitation, surface runoff and underground contribution, of which precipitation over the lake surface is the least significant. In the long term, using annual data, there is a remarkable memory of precipitation extending beyond five years, seen as a correlation with the accumulated precipitation anomaly (r2 = 0.76). This behavior should be explained by understanding relationship between the lake and its aquifer. Also important is the population growth, which affects the lake level in two ways: water extraction and water discharge. The models pointed out a nonlinear relationship between water level and the aforementioned variables, and suggest that the carrying capacity of the basin is around 90 thousand people, under current patterns of water consumption. It also indicates that, in order to allow lake recovery or to maintain system resilience, the anomaly of precipitation accumulated during several years should exceed 1000 mm. Although a correlation with land use was attempted, historical data do not reflect a trend that could be associated with water balance.
Example of Parameter Estimates for the Circumstellar Envelope of P Cyg

ASTRONOMY AND ASTROPHYSICS The relative figure of merit of optical interferometry as compared to spectroscopy Abstract. When planning new facilities, one is interested to know whether and by how much the new technique is superior to already existing ones. We describe a general approach permitting to evaluate the relative merits of various techniques used in astrophysical observations, following the theory of model parameter estimation. It is applied to compare two-aperture optical long baseline in-terferometry to classical spectroscopy, both used to define the model parameters of the P Cyg wind. The wind mod-eling was done using an efficient approximation for computation of the line source function; it allowed to analyse about 10 5 points in the parametric space of P Cyg envelope models. It is shown that interferometry offers no real advantage if the object can be described by stationary spherically symmetric models with a priori fixed thermal structure. However, if the object must be described by a model with a large number of free parameters, e.g. when the thermal structure of the envelope is not fixed a priori, then the interferometric measurements can reduce the error in model parameters determination by an order of magnitude. In the case of P Cyg, the reduction of errors provided by interferometry is highest for the baseline lengths in the range 45–90 m. This illustrates the capacity of the proposed method to be used for optimization of in-terferometric configurations. The simplifications adopted for this first trial application are critically analyzed, and future improvements are indicated.
Slip distribution and source parameters inverted from co-seismic deformation derived by InSAR technology of Wenchuan M_w7.9 earthquake

We have established a five-segment fault model based on field investigation and the linear noncoherent characteristics of InSAR wrapped deformation.The five-segment fault model is consistent with the surface rupture trace of field investigation at most of the segments.Then we use this fault model as constraints to simulate the co-seismic deformation of Wenchuan earthquake derived from InSAR technology.Our favored fault model contains five segments with varied dips, based on the seismogenic structure of precise aftershock relocation.The simulated deformation by forward modeling matches very well the InSAR data with a RMS of 0.3～0.35 m. The inverted slip distribution is concentrated in the depth of 0～20 km and the maximum slip is 10m.Among the largest-slip areas Beichuan area has relatively more concentrated slip at shallower depth than other areas.This may be the deep cause why Beichuan area is the most severely destroyed area in this earthquake.The inverted rake distribution shows that there is a transition along the direction of SW-NE.It is mainly reverse and some right-lateral slip at Wenchuan and Beichuan areas, but it is dominantly right-lateral with some thrusting in Qingchuan area, with the mean rake of 97° and 138° respectively.The inverted seismic moment M_O is 7.7×10~(20) N·m, and the moment magnitude M_w is 7.9.
