An Analysis of Regional Snow Assessments at Selected Hydrological Stations on the Danube and Tisza Rivers
Authors: Hamar Zsideková Beáta , Gauzer Balázs , Bálint Gábor
Published: October 2013

Precipitation falling on a land surface is one of the most important elements of the hydrological cycle, and it is the only input term of the water balance on the Earth´s surface. On those areas of the Earth where a part of the annual precipitation falls in the form of snow, the rhythm of the hydrological cycle, i.e., the water balance within a year, follows a pattern that deviates from that of the precipitation record. Precipitation falling in a solid state enters the hydrological cycle with a time lag that might be as much as several months after the precipitation event. Therefore, instead of considering the observed values of precipitation when describing the various elements of the hydrological cycle, it is more expedient to take the surface water input into account. This is a fraction of the precipitation which is present on the land surface in a liquid state. Consequently, the most important task of the various snow models within the rainfall - runoff and water budget schemes is to transform the precipitation values observed into surface water input values. Spring time runoff largely depends on the snowmelt component, and it gives the possibility of estimating the expected seasonal volume of the flow and flood peaks. Seasonal forecasts based on the relationship between snow resources and expected precipitation during the spring months have been analyzed for the Danube and Tisza rivers.

Authors: Mosavifeyzabadi S.H. , Vazin F. , Hassanzadehdelouei M.
Published: October 2013

In hot and arid regions, drought stress is considered as one of the main reasons for yield reduction. To study the effect of drought stress, nitrogen and zinc spray on the yield and yield components of corn, an experiment was carried out during the crop seasons of 2010 and 2011 on Emam Khomeyni research Farm in Mahvellat as a split factorial within randomized complete block design with three replicates. The main plots with irrigation factor and three levels were considered: full irrigation, stopping irrigation at anthesis step and stopping irrigation at the seed filling stage. Subplots were considered with and without nitrogen and zinc spray. The drought stress reduced the grain yield in anthesis stage more than other stages. Drought stress effects significantly on stem and ear diameter, ear length, chlorophyll value, leaf area index, leaf relative water content, stem, ear and leaves dry weight, number grain in ear and row, number row in ear, unfilled seed percentage and thousand grains weight. Nitrogen increased the seed yield and yield component except thousand grains weight and the number of row in ear. Using Zn, as compared with control treatment, causes the increase of grain yield, thousand grains weight and number grain in ear 16.5, 9 and 5.5%, respectively. The results obtained from the present research showed that anthesis stage was most sensitive stage to drought stress. Also nitrogen and Zn could somewhat reduce the impact drought stress on corn.

Published: October 2013

A field experiment was conducted to study the effect of different nitrogen management methods on yield, yield components and quality attributes of maize hybrids (single cross-6142 and double cross-4444) under irrigated conditions. Nitrogen dose is met either by PM (poultry manure) or urea according to each treatment. PM was incorporated at the time of presowing irrigation whereas fertigation method at knee height stage and foliar spray at flowering were use for the application of urea. Results showed that plant height, cob diameter, number of grains per cob, grain yield and biological yield were significantly affected by the hybrids. Significantly, higher plant height, cob diameter, number of grains per cob, grain yield and biological yield were produced by single cross-6142. There was no significant difference occur between both hybrids on seed oil and protein contents. N management by the application of T3 (60% N from PM + 38.5% N from urea through fertigation + 1.5% N from urea through foliar application) produced significantly more plant height, cob diameter, number of grains per cob, grain yield, biological yield, seed protein and seed oil contents. The interaction of single cross-6142 and T3 (60% N from PM + 38.5% N from urea through fertigation + 1.5% N from urea through foliar application) was found superior in production of more plant height, cob diameter and number of grains per cob. However, interaction between maize hybrids and N application methods for grain yield, biological yield, seed protein and oil contents was reported nonsignificant. It can be concluded that single cross hybrid-6142) and T3 (60% N from PM, 38.5% N from urea through fertigation and 1.5% N from urea through foliar application) could be used successfully for improving maize yield under the irrigated conditions.
The Effect of Long -Term Fertilization on the Grain Bean Harvest in Agricultural Research - Development Station Secuieni, Neamţ County, Romania, Conditions
Authors: Lupu Cornelia , Naie Margareta , Buburuz Alexandra-Andreea
Published: October 2013

The application of chemical fertilizers on the grain bean crop must be done due to the plant peculiarities (high consumption of nutrients, root system underrepresented, plant ability to synthesize up to 85% of the needed nitrogen) and its high sensitivity to stress conditions. Although the bean requirements for nutrients are high, the plant response to the application of fertilizers is smaller, the obtained production increase will vary widely depending on the type of fertilizer, the applied dose, but also on the climatic conditions in the area. The paper presents the experimental results, carried aut during 2008-2010 at Agricultural Research- Development Station Secuieni, Neamţ County, Romania (A.R.D.S. Secuieni- Neamţ), on the application of phosphorus and nitrogen fertilizers in a long - term experiences. By using the two fertilizers were obtained yield increases of 3-27%. These were directly proportional to the dose of the applied fertilizer. By applying the phosphorus fertilizer, the average production increases, compared with the control variant, were ranged from 7 to 15%. Average gains, obtained by the using of nitrogen fertilizers, compared with the control variant, were ranged from 12 to 27%. Marginal production increases, obtained by applying phosphorus fertilizers were of 1,52-2,92 kg beans/ kg P2O5, and at the nitrogen fertilizers, of 1,72-3,28 kg beans/ kg N. In both cases, the marginal increases obtained were inversely proportional to the doses of the apllied fertilizer.
Corridor Management
Authors: Anderson Scott A. , Rivers Benjamin S.
Published: October 2013

The primary assets of a transportation agency are the transportation corridors that have been established to provide the means for moving people and goods safely and efficiently. A corridor's performance in this regard is only as good as its weakest link. Therefore, to manage an asset such as a corridor to a standard for system performance is to consider its components concurrently, not by individual asset classes. A corridor has embankments, slopes, walls, bridges, and pavements, and considering these geotechnical features separately just does not make sense from a system-performance perspective. Settlement, slope instability, rockfall, erosion, and corrosion are events that can be surprises or can be recognized in advance and managed. The corridor concept can bring geo-technical assets into consideration and result in better management for system performance. The concept also provides a means for rational prioritization that allows for a phased approach to the daunting task of collecting inventory and condition assessment for features that have not previously been managed. Geoprofessionals are developing tools and practices for inventorying, assessing performance, predicting life-cycle costs and degradation, and evaluating risk associated with geotechnical features. These tools and practices contribute to effective corridor management.
Overcoming an Environmental Surprise with Innovative, Fast-Track Technology
Authors: Hughes Larry J. , Epperson Ann , Williams Tammy Keim
Published: October 2013

As the Tennessee Department of Transportation (DOT) was finalizing the future route of I-69 through northwest Tennessee, a previously unknown, unregulated landfill was discovered directly beneath the proposed route near its juncture with a continuing segment into Kentucky. The Tennessee DOT, cooperating with the Tennessee Department of Environment and Conservation, implemented a rapid-response, technology-driven strategy to assess the potential costs and liabilities of crossing the landfill versus avoiding it. After a concerted site-history investigation, an electromagnetic geophysical survey mapped the land-fill boundaries, established the area of fill, and identified areas of higher metal content within the fill. A concurrent soil–gas survey showed only isolated patterns of volatile organic compounds, often a driver for environmental mitigation costs. These results were used to optimize locations for subsurface drilling that employed the waste-minimizing sonic drilling technique. Depth of fill from exploratory drilling was combined with the geophysical delineation of landfill boundaries to yield an estimated waste volume of 65,000 m3 (85,000 yd3) within the proposed I-69 footprint. Chemical analyses were done for subsurface sonic rig soil cores, surface soil samples, the contents of drums scattered across the surface, and surface water. These analyses showed relatively modest environmental risk; it was suggested that if the landfill were excavated, most of the soil could be handled as nontoxic special waste. Nevertheless, considering both design–build factors and environmental issues, the cost of excavating and building through the landfill ($33.5 million) exceeded that of rerouting slightly east of the landfill ($29.5 million), and the route was diverted to avoid the landfill.
Influence of Contact Angle on Soil–Water Characteristic Curve with Modified Capillary Rise Method
Authors: Liu Zhen , Yu Xiong (Bill) , Wan Lin
Published: October 2013

The contact angle quantifies physicochemical interactions at the liquid–solid interface and is therefore critical to many physical processes that involve the interaction of soil and water. In geotechnical engineering, such interactions are the basis for the formulation of the soil–water characteristic curve (SWCC). However, the role of the contact angle in SWCCs has not been adequately recognized. A comprehensive study is reported on applying the capillary rise method (CRM) to measure the contact angles of soils. Analytical solutions to two forms of the Lucas–Washburn equation are presented to provide the theoretical basis for applying the CRM to soils. The disadvantages of conventional CRM analyses are demonstrated with experiments. A modified CRM was proposed on the basis of an analytical solution to a more complicated form of the Lucas–Washburn equation. This modified CRM exhibited reliable performance on numerous specimens made of a subgrade soil and a silicon dioxide sand. Testing procedures were designed and strictly followed, and innovative apparatuses for the preparation, transport, and accommodation of soil specimens were fabricated to ensure repeatability. For the modified CRM, experimental results for virgin specimens demonstrated good repeatability, and for sieved soils, clear trends were observed in the variations of contact angle with respect to pore size. Contact angles much greater than zero were observed for all tested specimens; this finding contradicts the assumption of perfect wettability in previous SWCC studies. In addition, it was demonstrated that neglecting the variations of contact angles with respect to pore radius could result in significant errors in SWCC construction.
Examining Effects of Climatic Factors on Flexible Pavement Performance and Service Life
Authors: Qiao Yaning , Flintsch Gerardo W. , Dawson Andrew R. , Parry Tony
Published: October 2013

The potential risk of climate change raises interest in how it may affect the deterioration rates of flexible pavements and how pavement service lives would be altered as a consequence. Previous studies demonstrated that temperature is the most influential environmental factor for the Mechanistic–Empirical Pavement Design Guide. In this study, temperature factors, both the increase in average annual temperature and the seasonal variation in temperature, are examined through a sensitivity analysis. The sensitivity of the pavement performance to temperature as well as other environmental factors such as precipitation, wind speed, percent sunshine, and groundwater level is included as a comparison. This study concluded that temperature factors, both the increase in average annual temperature and the seasonal variation, are the most influential in pavement performance. Moreover, pavement service life may experience considerable reduction because of climate change in some regions if design is not adapted to the changed climate.

Authors: Sirisha Kalam , Rajyalaxmi Injimuri , Olivia Sairem
Published: October 2013

N-aryl/heteryl acetoacetamides are the intermediates used in the synthesis of various heterocyclic compounds like 1,4-dihydropyridines, pyrimidines etc. Three different substituted N-aryl/heteryl acetoacetamide derivatives (I-III) have been prepared from the reaction of ethylacetoacetate and three different aryl/heteryl primary amines under solvent free conditions using potassium tert-butoxide as catalyst. The reactions were carried out by two different methods (viz., Conventional and Microwave irradiation) and they are simple, eco-friendly and economical. All reactions were processed for optimization with different ratios of aryl/heteryl amine and ethylacetoacetate like1:1,1:1.2,1:1.4,1:1.6,1:1.8,1:2 and a comparison was made between the percentage yields with each ratio. Highest percentage yield was observed with 1:1.8 ratio for I & II and 1:1.6 ratio for III in both the methods. However, the microwave irradiation method was found to be superior to the conventional method. The newly synthesized compounds have been purified by recrystallization and characterized by physical and spectral data.DOI: http://dx.doi.org/10.3329/icpj.v2i11.16533 International Current Pharmaceutical Journal, October 2013, 2(11): 189-192

Published: October 2013

Ficus exasperata has been extensively used in folk medicine for the treatment of many ailments. The aqueous extract of leaves of this herb reduced blood pressure through its cholinomimetic effect. In this study, different fractions of the crude extract of F. exasperata leaves (FEFIX) were evaluated on blood pressure. Fractionated extracts were obtained by successive use of different solvents on the total crude extract. Phytochemical analysis was performed for each fraction and increasing doses (0.25 to 40 mg / kg b.w.) were administered intravenously. The phytochemical screening showed that alkaloids and phenols were found in ethanol fraction (FE-FEFIX) and methanol fraction (FM-FEFIX). Saponins and tannins have been identified only in the aqueous fraction (FA-FEFIX). Decreases in blood pressure were 40.02 ± 3.08 mm Hg for the ethanol fraction (FE-FEFIX), 9.95 ± 2.09 mm Hg for the methanol fraction (FM-FEFIX) and 5.26 ± 1.46 mm Hg in the aqueous fraction (FA-FEFIX). Hypotension induced by ethanol fraction is found to be greater than those induced by the other two fractions. In conclusion, this study showed that the hypotensive effect of F. exasperata leaves was greater with its ethanol extract. Alkaloids and phenols present in this extract may be involved in the hypotensive effect.DOI: http://dx.doi.org/10.3329/icpj.v2i11.16534 International Current Pharmaceutical Journal, October 2013, 2(11): 193-195

Palestine : géopolitique d'une violence territoriale
Authors: Blanc Pierre
Published: October 2013

Le conflit israélo-palestinien est avant tout un conflit territorial dans lequel s’est révélée l’ingénierie du Yishouv puis surtout d’Israël. Le regard en surplomb que permet l’analyse historique dévoile bien une pensée stratégique dont les marques territoriales sont ici analysées. Même si cette pensée territoriale a procédé par à-coups, le fait qu’elle ait été portée toujours plus loin par les courants les plus extrémistes au sein du Yishouv puis d’Israël donne l’impression d’une progression « cohérente » autant qu’inéluctable. Privilégiant l’approche géohistorique, cet article cherche à analyser le fait territorial brut et ainsi à souligner la force de la violence territoriale dont fait montre Israël.
Le Hamas et Mohamed Morsi : un rapprochement trop risqué ?
Authors: Seurat Leïla
Published: October 2013

Les Frères musulmans palestiniens ont longtemps été dépendants du niveau de tolérance que les régimes successifs égyptiens accordaient à la Confrérie. La répression nassérienne à partir de 1954 ne fut ainsi pas sans conséquences sur les Frères musulmans de Gaza. Jusqu’en 1968, cette dépendance était d’autant plus affirmée que l’Égypte gérait administrativement la bande de Gaza ; moins forte depuis lors, elle est cependant demeurée, pendant des décennies, un élément structurant de la relation entre ces deux territoires. Cet équilibre s’est trouvé bouleversé par l’arrivée des Frères musulmans au pouvoir, ces derniers ayant opéré un rapprochement inédit avec le Hamas. La chute de Mohammed Morsi le 3 juillet 2013 pose à nouveau la question du traitement de Gaza par l’Égypte et de l’avenir du Mouvement de la Résistance Islamique.

The function of Zechariah 7–8 within the book of Zechariah
Authors: Im Yohan , Venter Pieter M.
Published: October 2013

It is argued that the function of Zechariah 7–8 in the book of Zechariah is central to the issue of the structure of Zechariah. It is proposed that a text-linguistic approach offers a new reading of Zechariah 7–8. It is further proposed that the larger segment of Zechariah 7:1–8:23 is a bridge (a transition from the preceding discourse to the subsequent discourse) that is connected to the prologue in Zechariah 1:1–6 and is developed and expanded in the subsequent discourses. This reading indicates the structure and the overall theme of Zechariah by viewing the book as a sequential discourse. This argument will be defended by studying the structure and the overall theme of Zechariah and emphasising the holistic aspect of the book of Zechariah.
Dentin Hypersensitivity: A Review of its Etiology, Mechanism, Prevention Strategies and Recent Advancements in its Management
Authors: Farooq Imran , Ali Saqib
Published: October 2013

Dentinal hypersensitivity is one of the most common clinical problem for which patients seek treatment and visit dental clinics. Its incidence is on a rise probably because its etiology is not very well understood. Once initiated, it can either remain as sensitivity or it can trigger pain and creates severe discomfort for the patient. Number of theories have been put forward to explain the mechanism of hypersensitivity causing pain but hydrodynamic theory is most widely accepted nowadays. Treating dentinal hypersensitivity is a challenge for dental professionals. This article reviews the etiology, mechanism and prevention strategies of dentinal hypersensitivity and also discusses recent advancements in its management.

Authors: Kankariya Vardhaman P , Ozulken Kemal , Cabot Florence , Yoo Sonia H
Published: October 2013

Purpose

To present refractive, visual and topographic outcomes of femtosecond laser assisted intrastromal ring segments (ISRS) implantation.

Settings

Bascom Palmer Eye Institute, Miami, FL, USA.

Materials and methods

Nineteen eyes of 15 patients with keratoconus, clear central corneas, and contact lens intolerance had implantation of a symmetrical 0.45 mm Inta cs segment (Addition Technology Inc, California, USA) using 200 kHz femtosecond laser (WaveLight GmbH, Erlangen, Germany). The outcomes of the procedure were evaluated in terms of uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BSCVA), average keratometry value (K-value) and spheric equivalent (SE).

Results

Femtosecond laser assisted ISRS implantation could be performed with ease, while no intra- or postoperative complications were encountered. Mean UCVA improved from 0.95 ± 0.39 to 0.66 ± 0.28 logMAR, mean BSCVA improved from 0.46 ± 0.13 to 0.29 ± 0.21 logMAR, mean spherical equivalent considerably reduced from −7.15 ± 4.57 to −4.38 ± 4.07 and K value reduced from 52.39 ± 5.79 to 49.78 ± 6.84 D at the last follow-up.

Conclusion

Using a 200 kHz femtosecond laser is a safe procedure providing optimal refractive, visual and topographic outcomes in our preliminary study.

Authors: González-Méijome Jose M , Peixoto-de-Matos Sofia Claudia , Queiros Antonio , Jorge Jorge M , Diaz-Rey Alberto
Published: October 2013

Purpose

To evaluate optical quality and visual function in keratoconus patients corrected with RGP contact lenses and a novel special design of silicone hydrogel contact lens.

Materials and methods

Twelve eyes of six patients with keratoconus were enrolled to experience a new soft contact lens (Soft-K) for keratoconus made of a silicone-hydrogel material and the outcomes were compared to the performance with gas permeable lenses and spectacles. The three situations were compared for monocular and binocular high (100%) and low contrast (10%) ETDRS LogMAR visual acuity and contrast sensitivity function (CSF).

Results

On average, there was an improvement of more than two lines in visual acuity over spectacle correction and this is statistically significant for both gas permeable (GP) and Soft-K lens (p < 0.001). Visual acuity was not significantly different between GP and Soft-K lens for high contrast acuity but was slightly higher with GP lens for low contrast under binocular conditions. Monocular CSF showed a marked improvement with the Soft-K lens and GP, compared to spectacles correction, particularly for medium and high frequencies; conversely.

Conclusion

Soft-K silicone hydrogel soft contact lens produces a clinical and statistically significant improvement in visual acuity and contrast sensitivity function over spectacle correction.

Retrospective Testing of the Score for the Detection of Ectasia Susceptibility: A Case Report of Ectasia 7 Years after LASIK
Authors: Saad Alain
Published: October 2013

A patient was treated bilaterally for myopia using laser in situ keratomileusis (LASIK). There was no evident tomographic risk factor for ectasia, but a slight asymmetry on the Placido topography in the left eye. Seven years postoperatively, a unilateral ectasia was diagnosed. Retrospectively, the calculated Score for the left eye was +0.2. This case suggests that an artificial intelligence system based on the combination of Placido and tomographic indices may be helpful for the detection of ectasia susceptible eyes.

On the supply of heavy planetary material to the magnetotail of Mercury
Authors: Delcourt D. C.
Published: October 2013

Abstract. We examine the transport of low-energy heavy ions of planetary origin (O+, Na+, Ca+) in the magnetosphere of Mercury. We show that, in contrast to Earth, these ions are abruptly energized after ejection into the magnetosphere due to enhanced curvature-related parallel acceleration. Regardless of their mass-to-charge ratio, the parallel speed of these ions is rapidly raised up to ~ 2 VE × B (denoting by VE × B the magnitude of the local E × B drift speed), in a like manner to Fermi-type acceleration by a moving magnetic mirror. This parallel energization is such that ions with very low initial energies (a few tenths of eVs) can overcome gravity and, regardless of species or convection rate, are transported over comparable distances into the nightside magnetosphere. The region of space where these ions reach the magnetotail is found to extend over altitudes similar to those where enhanced densities are noticeable in the MESSENGER data, viz., from ~ 1000 km up to ~ 6000 km in the pre-midnight sector. The observed density enhancements may thus follow from E × B related focusing of planetary material of dayside origin into the magnetotail. Due to the planetary magnetic field offset, an asymmetry is found between drift paths anchored in the Northern and Southern hemispheres, which puts forward a predominant role of heavy material originating in the Northern Hemisphere in populating the innermost region of Mercury's magnetotail.
The influence of seawater pH on U / Ca ratios in the scleractinian cold-water coral Lophelia pertusa

Published: October 2013

Abstract. The increasing pCO2 in seawater is a serious threat for marine calcifiers and alters the biogeochemistry of the ocean. Therefore, the reconstruction of past-seawater properties and their impact on marine ecosystems is an important way to investigate the underlying mechanisms and to better constrain the effects of possible changes in the future ocean. Cold-water coral (CWC) ecosystems are biodiversity hotspots. Living close to aragonite-undersaturation, these corals serve as living laboratories as well as archives to reconstruct the boundary conditions of their calcification under the carbonate system of the ocean. We investigated the reef-building CWC Lophelia pertusa as a recorder of intermediate ocean seawater pH. This species-specific field calibration is based on a unique sample set of live in-situ collected L. pertusa and corresponding seawater samples. These data demonstrate that uranium speciation and skeletal incorporation for azooxanthellate scleractinian CWCs is pH dependent. However, this also indicates that internal pH up-regulation of the coral does not play a role in uranium incorporation into the majority of the skeleton of L. pertusa. This study suggests L. pertusa provides a new archive for the reconstruction of intermediate water mass pH and hence may help to constrain tipping points for ecosystem dynamics and evolutionary characteristics in a changing ocean.
Pixel-based approach for building heights determination by SAR radargrammetry
Authors: Dubois C. , Thiele A. , Hinz S.
Published: October 2013

Abstract. Numerous advances have been made recently in photogrammetry, laser scanning, and remote sensing for the creation of 3D city models. More and more cities are interested in getting 3D city models, be it for urban planning purposes or for supporting public utility companies. In areas often affected by natural disaster, rapid updating of the 3D information may also be useful for helping rescue forces. The high resolutions that can be achieved by the new spaceborne SAR sensor generation enables the analysis of city areas at building level and make those sensors attractive for the extraction of 3D information. Moreover, they present the advantage of weather and sunlight independency, which make them more practicable than optical data, in particular for tasks where rapid response is required. Furthermore, their short revisit time and the possibility of multi-sensor constellation enable providing several acquisitions within a few hours. This opens up the floor for new applications, especially radargrammetric applications, which consider acquisitions taken under different incidence angles. In this paper, we present a new approach for determining building heights, relying only on the radargrammetric analysis of building layover. By taking into account same-side acquisitions, we present the workflow of building height determination. Focus is set on some geometric considerations, pixel-based approach for disparity map calculation, and analysis of the building layover signature for different configurations in order to determine building height.
Semi-Automatic Road/Pavement Modeling using Mobile Laser Scanning
Authors: Hervieu A. , Soheilian B.
Published: October 2013

Abstract. Scene analysis, in urban environments, deals with street modeling and understanding. A street mainly consists of roadways, pavements (i.e., walking areas), facades, still and moving obstacles. In this paper, we investigate the surface modeling of roadways and pavements using LIDAR data acquired by a mobile laser scanning (MLS) system. First, road border detection is considered. A system recognizing curbs and curb ramps while reconstructing the missing information in case of occlusion is presented. A user interface scheme is also described, providing an effective tool for semi-automatic processing of large amount of data. Then, based upon road edge information, a process that reconstructs surfaces of roads and pavements has been developed, providing a centimetric precision while reconstructing missing information. This system hence provides an important knowledge of the street, that may open perspectives in various domains such as path planning or road maintenance.
The Application of a Car Confidence Feature for the Classification of Cross-Roads Using Conditional Random Fields
Authors: Kosov S. , Rottensteiner F. , Heipke C. , Leitloff J. , Hinz S.
Published: October 2013

Abstract. The precise classification and reconstruction of crossroads from multiple aerial images is a challenging problem in remote sensing. We apply the Conditional Random Fields (CRF) approach to this problem, a probabilistic model that can be used to consider context in classification. A simple appearance-based model is combined with a probabilistic model of the co-occurrence of class label at neighbouring image sites to distinguish classes that are relevant for scenes containing crossroads. The parameters of these models are learnt from training data. We use multiple overlap aerial images to derive a digital surface model (DSM) and a true orthophoto without moving cars. From the DSM and the orthophoto we derive feature vectors that are used in the classification. Within our framework we make use of a car detector based on support vector machines (SVM), which delivers car probability values. These values are used as additional feature to support the classification when the road surface is occluded by static cars. Our approach is evaluated on a dataset of airborne photos of an urban area by a comparison of the results to reference data. The evaluation is performed for images of different resolution. The method is shown to produce promising results when using the car probability values and higher image resolution.
Integration of spectral information and photogrammetric DSM for urban areas classification
Authors: Nex F. , Dalla Mura M. , Remondino F.
Published: October 2013

Abstract. The automated classification of urban areas in one of the main topic in the Geomatics domain. Several papers dealing with this topic have been already presented in the last decade. Most of these approaches uses multi-spectral or LiDAR data or both of them as input. In this paper, an algorithm for urban areas classification based only on overlapping RGB images is presented. The integration of radiometric and geometric information derived from aerial images is exploited in order to extract the three main classes of urban areas (i.e. building, vegetation and road) in automated way and without prior information. A photogrammetric Digital Surface Model (DSM) is firstly generated applying dense image matching techniques and this information as well as some spatial features provided by morphological filters are combined to derive a first classification. Subsequently, a thematic classification of the surveyed areas is performed considering the surface’s reflectance in the visible spectrum of the used images and the multi-image information provided by the overlapping images. Range and image information are so merged in an algorithm that allows the reciprocal and iterative sharing of information in order to increase the reliability and completeness of the classification process. After a detailed description of the algorithm, the achieved results over dense urban areas are shown and discussed.

Forging an Incarnational Theology Two Score Years after Nostra Aetate
Authors: Svartvik Jesper
Published: October 2013

Surveying how Christology is formulated in the wake of Nostra Aetate, this paper concentrates on three models: (1) The man became words, words, words; the quest for the historical Jesus has often emphasised the â allegedly unique â teachings of the Nazarene. Its main problem, however, is that the contemporaries of Jesus are no longer presented as his historical context but as his theological contrast. (2) The word became fleshwounds; due to Mel Gibson’s movie The Passion of the Christ one single Greek word (Mk 15:15; fragellosas, i.e., ”after having flogged”) has been at the centre of the Christological discussion during 2004. His version of the medieval passion plays highlights its particular problems. Having first described the flaws of these two models, the paper will seek to explore how â two score years after the declaration Nostra Aetate â the Johannine statement that the Word became flesh could be helpfully articulated today.
"With Sincere Reverence": A Christological Perspective for the Interreligious Dialogue Envisioned by Nostra Aetate
Authors: Gamberini, SJ Paolo
Published: October 2013

Theologians have a particular task to provide discernment when expressing in interreligious dialogue the Christological proclamation that Jesus Christ is "'the way, the truth, and the life,' (Jn 14:6), in whom people may find the fullness of religious life, in whom God has reconciled all things to Himself" (Nostra Aetate, Â§3). Therefore, there is a need to renew the spirit of the Conciliar Declaration Nostra Aetate,, which reminds us that the Catholic Church rejects nothing that is true and holy in the other religions. The Church acknowledges with sincere reverence ("sincera cum observantia") that the other often religions reflect a ray of that Truth which enlightens all people. In this article, I highlight three different moments in which this sincere reverence towards other religions may be realized. The first moment may be called methodological and refers to the Ignatian tradition of the Spiritual Exercises. I develop first of all the praesupponendum (presupposition) as an attitude of being able to listen to the religious experience of the other; then the contemplatio ad amorem (contemplation in attaining love), as awareness and recognition of the action of the Spirit: being able to distinguish the religious experience of God from its theoretical and practical interpretations; finally the magis, the continuing transcending of the religious conscience in reaching out God: Deus semper maior (God is always greater). The second moment of my paper is more theoretical. I deal with the question of Truth within the interreligious dialogue and how God’s ineffable transcendence and otherness have been revealed in this Jesus of Nazareth; "No one has seen God at any time; the only begotten God who is in the bosom of the Father, He has explained Him" (Jn 1:18). The humanity of God, Jesus’ particularity, is not a limitation for interreligious dialogue, but constitutes an adequate perspective for determining the universality of Jesus Christ. The third moment considers the practical dimension of the dialogue. I relate the inner otherness of God (Trinity) with God’s becoming other than himself (Incarnation), showing how the evangelical praxis of the believer, who makes himself everything for everybody, is able in the praxis, more than in theory, to sustain the eschatological tension between the already and not yet that is characteric of interreligious dialogue.
Can Catholicism Validate Jewish Biblical Interpretation?
Authors: Levenson Jon D.
Published: October 2013

This article analyses the Pontifical Biblical Commission's 2001 study, The Jewish People and Their Sacred Scriptures in the Christian Bible and its significance for Christian-Jewish relations. While praising the study for addressing a large and complex issue, the essay raises some questions about particularity and relativism, elements of supersessionism, and inter-textuality.
Rabbi Joseph Soloveitchik''s ‘Confrontation’: A Reassessment
Authors: Breger Marshall J.
Published: October 2013

Responding to a recent symposium on Rabbi Joseph Soloveitchik's 1964 article on the propriety of Christian-Jewish dialogue, this essay begins by assessing several arguments put forth by Soloveitchik. These include the incommensurability of religious faith, the risks interreligious dialogue presents to the Jewish minority, the dangers of syncretism, and the ability to separate neatly the sacred and the profane. The article then proceeds to discuss the nature of Catholic-Jewish today, and concludes with thoughts about the future of Christian and Jewish interaction.
Christian Prayer and Song in a Post-Holocaust Church
Authors: Anderson E. Byron
Published: October 2013

Because liturgy also is ritual and rite through which patterns of linguistic, homiletic, musical, and embodied practices are repeated over time and by which Christian persons are formed, we must pay close attention to the subtle ways in which the “liturgy of supersessionism” persists in our churches. To this end, this article explores questions about the Christian use of the Tetragrammaton in prayer and song; the distinction, or lack thereof, between Sabbath and Sunday; the relationship between the dating of Easter and Passover; and the ways in which Christian prayer and song portray the relationship between Israel and the Church.

The Church Struggle and the Confessing Church: An Introduction to Bonhoeffer's Context
Authors: Hockenos Matthew D.
Published: October 2013

This article traces the German church struggle form 1933 to 1945 with particular emphasis on Dietrich Bonhoeffer’s role. Although Bonhoeffer’s status in the world today is that of a great theologian and courageous opponent of the Nazi regime, he did not have much of an impact on the direction of the Confessing Church during the church struggle. Bonhoeffer’s striking albeit marginal role in the German church struggle and his inability to affect significantly the direction of the Confessing Church was due to many factors, including his young age, his liberal-democratic politics, his absence from Germany from October 1933 to April 1935, his vacillating and at times contradictory positions on central issues, his radical theological critique of the Nazi state, his friendship with and family ties to Christians of Jewish descent, and ultimately his willingness to risk his life to destroy Hitler’s regime.

Heschel’s Monotheism vis-à-vis Pantheism and Panentheism
Authors: Merkle John C.
Published: October 2013

The foundation of Abraham Joshua Heschel’s theology is the most hallowed claim about God in the Jewish tradition: “Hear, O Israel, the Lord is our God, the Lord is One” (Dt. 6:4). Heschel echoes the tradition in claiming that this means not simply that there is only one true God, but also that God possesses inner unity, which is the necessary precondition for unity in the world. Pantheism is one way of explaining unity in the world, and though there a few passages in Heschel’s writings that have a pantheistic ring to them, this article shows that Heschel clearly espouses a monotheistic perspective as opposed to a pantheistic one. Recognizing that Heschel’s theology is not pantheistic, some authors have called his theology panentheistic, but this article argues why, despite Heschel’s strong emphasis on God’s all-embracing presence, this is a misleading designation.
Jacques Maritain and the Jewish Question: Theology, Identity and Politics
Authors: Ventresca Robert A.
Published: October 2013

This article calls for a reconsideration of Jacques Maritain’s philosophical and theological reflections on the ‘Jewish Question’, on anti-Semitism and, more broadly, on Jewish-Christian relations in modern history. The article follows two broad lines of enquiry. First, it sketches a general outline of Maritain’s arguments against Catholic-Christian anti-Semitism, and his proposals for workable solutions to what he identified as the ‘Jewish problem’ in European life. Second, the article considers the practical value of Maritain’s visions of a ‘new Christendom’, that is, of a new political regime based on Gospel-values and thus recognizing the complete civic equality, political and religious freedoms of European Jews. The article concludes that all of Maritain’s thought on the Jewish question must be read through the lens of his Christian eschatological view.
