Expert Opinion on Managing Chronic HCV in Patients with Non-Hodgkin Lymphoma and other Extrahepatic Malignancies
Authors: Ferri Clodoveo , Feld Jordan J , Bondin Mark , Cacoub Patrice
Published: November 2018

HCV is a carcinogen that is well established as a major risk factor for hepatocellular carcinoma. Evidence that HCV plays a role in the development of extrahepatic malignancies is less robust; however, epidemiological studies have consistently demonstrated an association between HCV infection and B-cell non-Hodgkin lymphoma (NHL). The strongest evidence for a link between HCV and tumouri-genesis is the clear association between viral eradication, as indicated by achievement of sustained virological response, and remission of B-cell NHL. All-oral direct-acting antiviral-based therapies are effective in patients with HCV-associated NHL and well tolerated. For this reason, it is important that clinicians assess HCV-infected patients for HCV-associated extrahepatic malignancies so patients can receive timely diagnosis and treatment.

Fragments d’un dictionnaire oublié. Essai de datation du Parisinus arabicus 4235 de la BnF
Authors: Jaouhari Mustapha
Published: November 2018

[fr] Le manuscrit de Paris, BnF, arabe 4235 est une copie fragmentaire du dictionnaire al-Bāri‘ d’Abū ‘Alī l-Qālī (m. 356/967) ayant appartenu à un certain Ibrāhīm b. Ḥumām b. Aḥmad sur qui nous ne connaissons rien. En revanche, son père, Ḥumām b. Aḥmad al-Uṭrūš, a vécu à Cordoue de 357/968 à 421/1030. Il y enseignait, entre autres, la langue et la poésie et, en même temps, copiait des livres pour gagner sa vie pendant les dures années de la crise califale. Une glose au folio 22b, tirée d’un codex personnel d’Abū ‘Alī l-Qālī laisse penser que son transcripteur avait accès aux documents de celui-ci, et montre que le manuscrit parisien provient d’un milieu cordouan privilégié. Le soin orthographique et philologique accordé à cette copie ainsi que son style graphique singulier font d’elle plutôt l’oeuvre d’un maître de langue que le travail d’un copiste scrupuleux. Outre le contexte de sa production, des indices codicologiques et paléographiques militent en faveur d’une datation de la fin du IVe/Xe siècle voire du début du siècle suivant.
El color rojo según el Kitāb al-Mujaṣṣaṣ de Ibn Sīdah. Una aportación a la lexicografía árabe
Authors: Serrano-Niza Dolores
Published: November 2018

Es muy frecuente encontrar en la lexicografía bilingüe términos relativos al campo semántico del color en los que una misma palabra árabe aparece con diferentes equivalentes en las lenguas occidentales. Sin embargo, no existe suficiente producción científica al respecto por lo que, el objetivo de este trabajo será, tomando como ejemplo el color rojo, comenzar a construir el campo semántico del color en la lengua árabe a través de un análisis sincrónico basado en la lexicografía árabe medieval. Mi principal fuente es el Kitāb al-Mujaṣṣaṣ de Ibn Sīdah, del que selecciono un corpus léxico en el que solo tendré en cuenta los paradigmas del nombre de color. Las definiciones que Ibn Sīdah ofrece han sido contrastadas con las dadas en otros diccionarios bilingües de referencia para desarrollar esta investigación. Dicho análisis se ha realizado utilizando una metodología propia y cercana a la de la disciplina de la “Terminología”, con el fin de asentar las bases para construir un futuro campo semántico del color en lengua árabe.
Discusiones sobre la teología de al-Bāqillānī en el Magreb: el Tasdīd fī šarḥ al-Tamhīd de ‘Abd al-Ŷalīl b. Abī Bakr al-Dībāŷī al-raba‘ī
Authors: Ansari Hassan , Thiele Jan
Published: November 2018

En este artículo presentamos un manuscrito único de un comentario magrebí del Kitāb al-Tamhīd de al-Bāqillānī datado en el siglo V/XI. La obra se titula al-Tasdīd fī šarḥ al-Tamhīd escrita por ‘Abd al-Ŷalīl b. Abī Bakr al-Dībāŷī —también conocido como Ibn al-Ṣābūnī— quien estudió el Tamhīd con otros discípulos de al-Bāqillānī en Qayrawān. El presente estudio revisa el proceso de transmisión de la obra de al-Bāqillānī en el Occidente Islámico. Después continúa presentando al autor del comentario, reconstruyendo la génesis del texto y describiendo su contenido. La sección final escoge un capítulo del texto que se ha seleccionado para demostrar cómo al-Dībāŷī sigue la posición tardía de al-Bāqillānī con respecto a la llamada teoría de los aḥwāl- duramente criticada en el Tamhīd. El Tasdīd constituye uno de los textos más antiguos del aš‘arismo magrebí que ha llegado hasta nosotros, ofreciéndonos nuevas y valiosas perspectivas sobre la historia de esta escuela teológica en el Occidente islámico.
The GTPase Rab1 Is Required for NLRP3 Inflammasome Activation and Inflammatory Lung Injury

Published: November 2018

Uncontrolled inflammatory response during sepsis predominantly contributes to the development of multiorgan failure and lethality. However, the cellular and molecular mechanisms for excessive production and release of proinflammatory cytokines are not clearly defined. In this study, we show the crucial role of the GTPase Ras-related protein in brain (Rab)1a in regulating the nucleotide binding domain-like receptor family, pyrin domain containing 3 (NLRP3) inflammasome activation and lung inflammatory injury. Expression of dominant negative Rab1 N124I plasmid in bone marrow–derived macrophages prevented the release of IL-1β and IL-18, NLRP3 inflammasome activation, production of pro–IL-1β and pro–IL-18, and attenuated TLR4 surface expression and NF-кB activation induced by bacterial LPS and ATP compared with control cells. In alveolar macrophage–depleted mice challenged with cecal ligation and puncture, pulmonary transplantation of Rab1a-inactivated macrophages by expression of Rab1 N124I plasmid dramatically reduced the release of IL-1β and IL-18, neutrophil count in bronchoalveolar lavage fluid, and inflammatory lung injury. Rab1a activity was elevated in alveolar macrophages from septic patients and positively associated with severity of sepsis and respiratory dysfunction. Thus, inhibition of Rab1a activity in macrophages resulting in the suppression of NLRP3 inflammasome activation may be a promising target for the treatment of patients with sepsis.
Survey on broiler pre-slaughter mortality in a commercial abattoir of central Italy
Authors: Grilli Claudia , Stocchi Roberta , Loschi Anna Rita , Conti Fabrizio , Rea Stefano
Published: November 2018

The pre-slaughter mortality was investigated on broilers, in the Mediterranean climate condition, considering the most significant risk factors as the journey length, waiting time, season and the space allowance in cages. At first, the pre-slaughter mortality was studied considering the totality of birds and then by examining in detail three broiler categories: large, medium and small size. The average dead on arrival (DOA) recorded on the totality of birds throughout the year was 0.38% and the values obtained in winter, spring, summer and autumn were 0.52, 0.48, 0.31 and 0.22%, respectively. The mortality rate observed during the year was 0.52, 0.47 and 0.31% for large, medium and small broilers, respectively. In all three groups, the maximum values of mortality were obtained in winter, whereas the minimum ones were recorded in autumn, spring and summer for large, medium, and small size birds, respectively. The increase of journey length could cause a higher mortality rate whereas the increase of the waiting time in the facilities at controlled environmental conditions did not seem to be a risk factor, but rather a mean to reduce the number of dead animals (all P < 0.05). It is concluded that the resistance to the hostile weather conditions, long journeys and extended waiting times was strongly related with the body weight of broilers; therefore, the planning of the slaughtering activity should consider this aspect, in order to avoid animal suffering and the economic loss.
Growth potential of Listeria monocytogenes in six different RTE fruit products: impact of food matrix, storage temperature and shelf life
Authors: Ziegler Matthias , Rüegg Simon , Stephan Roger , Guldimann Claudia
Published: November 2018

We tested the growth potential of Listeria monocytogenes on six RTE fruit products at low (4°C at the factory followed by 8°C retail/home storage) and abusive (4°C followed by 12°C) storage temperatures. Sliced coconut and fresh cut cantaloupe, as well as a fruit mix containing diced pineapple, cantaloupe, apples and grapes supported the growth of L. monocytogenes with a growth potential d>0.5 log CFU/g over six days. Mangoes, a mix of diced kiwi, cantaloupe and pineapple as well as a mix of diced pineapple, mango, grapefruit, kiwi and pomegranate did not support a growth potential that exceeded 0.5 log CFU/g over six days. The growth potential of L. monocytogenes correlated significantly with the pH; no product with a pH below 4 showed a significant growth potential of L. monocytogenes. Time after inoculation was also a significant predictor of the growth potential, while the fruit type and storage temperature were not.

Published: November 2018

Cadmium (Cd) concentrations were evaluated in the samples of kidney, liver and muscle of sixty-six buffaloes regularly slaughtered. Forty were raised in Campania, in the territory between the province of Naples and Caserta and twenty-six were bred in Apulia, in the province of Bari. Two aliquots were prepared for the renal and hepatic samples: one intended for the chemical analysis and the other one intended for histological investigations. Muscle samples were the subject of purely chemical investigation. In the group of forty animals raised in the Campania region, the limits imposed by EC Reg. 1881/2006 and EC Reg. 488/2014 were exceeded in three renal samples, which showed values of 1.53, 1.22 and 1.1 mg/kg respectively; in three hepatic samples, which presented values of 0.72, 0.64 and 0.61 mg/kg, and in five muscle samples, with values of 0.16, 0.16, 0.09, 0.08 and 0.07, respectively. On the other hand, in the group of animals raised and slaughtered in the province of Bari, none of the twenty-six samples examined exceeded the limits imposed by the European regulations. The histological analysis showed typical, but not pathognomonic lesions in the renal samples from the animals raised in the provinces of Naples and Caserta. The levels of Cd contamination found in the samples examined suggest that it would be correct to exclude from the human consumption, as it happens for the equines, the kidney and the liver, especially from the animals raised in some geographical areas with a high rate of pollution.
Contribution of vegetables and cured meat to dietary nitrate and nitrite intake in Italian population: Safe level for cured meat and controversial role of vegetables
Authors: Roila Rossana , Branciari Raffaella , Staccini Benedetta , Ranucci David , Miraglia Dino , Altissimi Maria Serena , Mercuri Maria Lucia , Haouet Naceur M.
Published: November 2018

Nitrate and nitrite content was determined on a total of 900 samples of vegetables and cured meat and the nitrite and nitrate exposure assessment was evaluated for central Italy population based on the food consumption data reported by the national dietary surveys. The highest average content of nitrate was detected in rocket salad (4415 mg/kg) and radish (3817 mg/kg) and for cured meat in “Bresaola” (188 mg/kg) and in Bacon (178 mg/kg). The nitrite content was negligible both in vegetables than in cured meat. The average consumption among population resulted 3.45 g/kg bw/die and 0.62 g/kg bw/die for vegetables and cured meat respectively. The obtained data confirm that nitrate ADI was higher than the limits of 3.7 mg/kg bw/die for infants and was the highest exposure level for people of all ages. Cured meat consumption did not contribute to nitrate ADI exceedance neither as a mean nor as 99th percentile of exposure.

Mesospheric bores at southern midlatitudes observed by ISS-IMAP/VISI: a first report of an undulating wave front
Authors: Hozumi Yuta , Saito Akinori , Sakanoi Takeshi , Yamazaki Atsushi , Hosokawa Keisuke
Published: November 2018

Abstract. Large-scale spatial structures of mesospheric bores were observed by the
Visible and near-Infrared Spectral Imager (VISI) of the ISS-IMAP mission
(Ionosphere, Mesosphere, upper Atmosphere and Plasmasphere mapping mission
from the International Space Station) in the mesospheric O2 airglow
at 762 nm wavelength. Two mesospheric bore events in southern midlatitudes
are reported in this paper: one event at 48–54∘ S,
10–20∘ E on 9 July 2015 and the other event at 35–43∘ S,
24∘ W–1∘ E on 7 May 2013. For the first event, the
temporal evolution of the mesospheric bore was investigated from the
difference of two observations in consecutive passes. The estimated eastward
speed of the bore is 100 m s−1. The number of trailing waves increased
with a rate of 3.5 waves h−1. Anticlockwise rotation with a speed of
20∘ h−1 was also recognized. These parameters are similar to
those reported by previous studies based on ground-based measurements, and
the similarity supports the validity of VISI observation for mesospheric
bores. For the second event, VISI captured a mesospheric bore with a
large-scale and undulating wave front. The horizontal extent of the wave
front was 2200 km. The long wave front undulated with a wavelength of
1000 km. The undulating wave front is a new feature of mesospheric bores
revealed by the wide field of view of VISI. We suggest that nonuniform bore
propagating speed due to inhomogeneous background ducting structure might be
a cause of the undulation of the wave front. Temperature measurements from
the Sounding of the Atmosphere using Broadband Emission Radiometry (SABER)
onboard the Thermosphere, Ionosphere, Mesosphere, Energetics and Dynamics
(TIMED) satellite indicated that bores of both events were ducted in a
temperature inversion layer.
Impact of anthropogenic and biogenic sources on the seasonal variation of the molecular composition of urban organic aerosols: a field and laboratory study using ultra-high resolution mass spectrometry

Abstract. This study presents the molecular composition of OA using ultra-high resolution mass spectrometry (Orbitrap) at an urban site in Central Europe (Zurich, Switzerland). Specific source spectra were also analysed, including samples representative of wood burning emissions from Alpine valleys during wood burning pollution episodes and chamber investigations of wood smoke as well as samples from Hyytiälä strongly influenced by biogenic secondary organic aerosol. While samples collected during winter in Alpine valleys have a molecular composition remarkably similar to fresh laboratory wood burning emissions, winter samples from Zurich are influenced by more aged wood burning emissions. In addition, other organic aerosol emission or formation pathways seem to be important at the latter location in winter. Samples from Zurich during summer are similar to those collected in Hyytiälä, predominantly impacted by oxygenated compounds with an H / C ratio of 1.5, indicating the importance of biogenic precursors for SOA formation at this location. We could explain the strong seasonality of the molecular composition at a typical European site by primary and aged wood burning emissions and biogenic secondary organic aerosol formation during winter and summer, respectively. Results presented here likely explain the seasonally rather constant predominance of non-fossil organic carbon at European locations.
Homogeneity criteria within IASI pixels for the preparation of an
all-sky assimilation
Authors: Farouk Imane , Fourrie Nadia , Guidard Vincent
Published: November 2018

Abstract. This article focuses on a selection of satellite infra-red IASI observations and their simulation in the global Numerical Weather Prediction (NWP) system ARPEGE (Action de Recherche Petite Echelle Grande Echelle), using the sophisticated radiative transfer model RTTOV-CLD which takes into account the cloud multi-layers and the cloud scattering from atmospheric profiles and cloudy microphysical parameters (liquid water content, ice content and cloud fraction). The aim of this work is to select homogeneous scenes by using information of the collocated Advanced Very High Resolution Radiometer (AVHRR) pixels inside each IASI field of view and to retain the most favourable cases for the assimilation of IASI infrared radiances. Two methods to select homogeneous scenes using homogeneity criteria already proposed en the literature were employed; criteria derived from Martinet et al. (2013) for cloudy sky selection in the French mesoscale model AROME (Applications of Research to Operations at MEsoscale), and the criteria from Eresmaa (2014) for clear sky selection in the global model IFS (Integrated Forecasting System). An intercomparison between these methods reveals considerable differences, either in the method to compute the criteria or in the statistical results. From this comparison a revised method is proposed that is a compromise between the different tested methods, using the two infrared AVHRR channels to define the homogeneity criteria in the brightness temperature space. This revised method has a positive impact on the observation statistics minus the 15 simulation statistics, while retaining 36 % observations for the assimilation. It was then tested in the NWP system ARPEGE and tested for the clear-sky assimilation. These criteria were added to the current data selection based on the Mc Nally and Watts (2003) cloud detection. It appears that the impact on analyses and forecast is rather neutral.
How bias correction goes wrong: Measurement of XCO2 affected by
erroneous surface pressure estimates
Authors: Kiel Matthäus , O'Dell Christopher W. , Fisher Brendan , Eldering Annmarie , Nassar Ray , MacDonald Cameron G. , Wennberg Paul O.
Published: November 2018

Abstract. Currently all measurements of XCO2 from space have systematic errors. To reduce a large fraction of these errors, a bias correction is applied to XCO2 retrieved from GOSAT and OCO-2 spectra using the ACOS retrieval algorithm. The bias correction uses, among other parameters, the surface pressure difference between the retrieval and the meteorological reanalysis. Erroneous surface pressure estimates, however, propagate nearly 1 : 1 into bias-corrected XCO2. For OCO-2, small errors in the knowledge of the pointing of the observatory (up to ∼ 130 arcsec) introduce a bias in XCO2 in regions with rough topography. Erroneous surface pressure estimates are also caused by a bug in ACOS version 8, sampling meteorological analyses at wrong times (up to three hours after the overpass time). Here, we derive new geolocations for OCO-2's eight footprints and show how using improved knowledge of surface pressure estimates in the bias correction reduces errors in OCO-2's v9 XCO2 data.
Particulate trace metal dynamics in response to increased CO2 and iron availability in a coastal mesocosm experiment
Authors: Lorenzo M. Rosario , Segovia María , Cullen Jay T. , Maldonado María T.
Published: November 2018

Abstract. Rising concentrations of atmospheric carbon dioxide are causing ocean acidification and will influence marine processes and trace metal biogeochemistry. The importance of the combined impacts of elevated CO2 and changes in trace metal availability on marine plankton remain largely unknown. A mesocosm experiment was performed to study changes in particulate trace metal concentrations during a bloom dominated by the coccolithophore Emiliania huxleyi. We employed a full-factorial experimental design, comprising all combinations of ambient and elevated pCO2 and dissolved iron (dFe). Particulate metal concentrations (Fe, Cu, Zn, Co, Mn, Cd, Mo, Ti and Pb) were determined by high-resolution inductively coupled plasma mass spectrometry (HR-ICPMS). We examined biogenic and lithogenic sources of particulate metals, and their evolution during the experiment. Biogenic metal concentrations were estimated from bulk particle measurements by comparing phosphorus (P)-normalised quotas with published ratios, as well as concentrations of particulate trace metals in the presence and absence of an oxalate-EDTA wash. Our results demonstrate that particulate Ti and Fe concentrations were dominated by lithogenic material in the fjord. In contrast, particulate Cu, Co, Mn, Zn, Mo and Cd concentrations correlated with P concentrations and phytoplankton biomass, indicative of their strong biogenic character. Furthermore, ocean acidification changed the relative concentrations of particulate metals; a result mainly driven by the effects of ocean acidification on the growth of different phytoplankton phyla. This study demonstrates the utility and robustness of combining trace metal analyses of particles in a controlled mesocosm experiment with manipulations of CO2 and Fe concentrations using natural assemblages of marine phytoplankton.
IMPORTANCE OF INCORPORATION OF GEOSPATIAL TECHNOLOGY APPLICATIONS IN WATER RESOURCES AT GRADUATE AND POST-GRADUATE COURSES OF CIVIL ENGINEERING

Published: November 2018

Abstract. Water is a very crucial element to sustain life on earth. The availability of water varies both spatially and temporally. India being a water stress country, the per capita availability of water is reducing with time. It is predicted that by 2050 around 54% of the country will be water scarce. The changing climate along with the ever-increasing population is putting additional stress on water availability. The science of water, its availability and distribution on earth and its atmosphere, is generally regarded as hydrology. The important aspects of hydrology and hydraulic or more broadly water resources are taught as the subject or optional subjects the branch of Civil Engineering at almost all engineering institutes/colleges at the undergraduate level. It is also one of the specializations for post-graduate level studies. It is, by now, well proven that the geospatial technology play crucial role in water resources assessment, planning and management. However, the young minds (graduate and post-graduate students) are just being trained for typical hydrology using traditional means and approaches. The advancement and potential of geospatial technology has drawn the attention of academician, and it has been started as a subject mostly at the post-graduate courses. Recently, some of the institutions have started courses on geo-informatics at the graduate level. However, the hydrology and geospatial technology are generally taught as two separate subjects under different course at different levels mostly under the broad subject of Civil Engineering. The present paper emphasis on needs and ways of updating Civil Engineering course curriculum by focusing on incorporation of applications of geospatial technology in hydrology as regular subject.
QUALITY OF URBAN LIFE: IDENTIFICATION OF LIVABLE URBAN SPACES WITHIN MUMBAI METROPOLITAN REGION
Authors: Gawai N. , Phadke A.
Published: November 2018

Abstract. The quality of urban life has become one of the most pertinent issues in contemporary times in India. There have been several reports published by government and nongovernmental agencies listing out various dimensions of quality of urban life but in a half-hearted manner as some reports have focused just upon the quality of urban air or some governmental reports talk about Human Development Index. There has hardly been any holistic effort to scale the quality of urban life in terms of economic, social, cultural, environmental and psychological well-being. Unless all these parameters are combined, one cannot furnish the livability index of micro urban spaces within major metropolitan regions. The calculation of livability index thus needs to take into account environmental, socio-economic and mental dimensions. The environment related data has been achieved by extracting NDVI through LANDSAT satellite imagery for the month of May, 2018. NDVI has been used for calculating green spaces index. The data related to socio-economic parameters have been collected through primary and secondary sources of data. The data related to psychological health is gathered through questionnaire survey and personal interviews. Ranking based index calculation has been applied to arrive at a common livability index of select sub spaces in Mumbai Metropolitan Region. The outcomes are very interesting and helpful in comparative analysis of select sub-spaces vis-à-vis quality of life. It has also helped in the identification of stressed sub-regional or micro spaces. Such livability index will be highly useful in regional and urban planning. The research aims at calculating livability index for select sub-regional spaces in Mumbai Metropolitan Region.
ACCESSIBILITY ASSESSMENT: TRAINING THE SLUM RESIDENTS IN SCALING THE ‘ACCESSIBILITY’
Authors: Phadke A.
Published: November 2018

Abstract. With almost half of the developing world turning ‘urban’, it becomes a major challenge for the local self-governments to assure availability and accessibility of basic infrastructural facilities to citizens at affordable rates. The issues of accessibility become especially complicated in the cities of Global South as ‘accessibility’ is highly politicized and governed by various forces that shape social, cultural and economic hierarchies. The city space not only experiences spatial segregation but also a peculiarly linked social segregation that runs along ethnic identities creating conditions of social and economic polarization at not only macro level as well as at micro levels within slums that house lower income groups (LIG) and economically weaker sections (EWS). The conditions of inaccessibility decisively affect the wellbeing of these groups leading to erosion of social and mental wellbeing. The effective implementation of various welfare schemes also mostly remains inadequate due to the highly complicated nature of ‘inaccessibility’ and lack of transparency.For effective implementation of various welfare schemes, the government has already moved towards ‘e-governance’. Ironically, the use of ‘smart’ technology remains restricted to higher income groups and the LIG and EWS gets excluded again due to lack of knowledge. In fact, these sections of urban population who suffer absolutely due to conditions of ‘inaccessibility’ need to be trained and involved in measuring the levels of accessibility and improving access to various basic infrastructural facilities. The paper will attempt at introducing a module that is based in simpler technologies like ODK (open data kit) and Quantum GIS to train the slum residents in mapping the accessibility vis-à-vis basic infrastructural facilities and improve the accessibility through positive deliberations with the local selfgovernments.
SEMANTIC MODELING OF UTILITY NETWORKS IMPLEMENTATION OF USE CASES FOR DEHRADUN CITY
Authors: Vishnu E. , Saran S.
Published: November 2018

Abstract. The current on-going boom in the field of Building Information Modeling (BIM) and 3D GIS is widely being explored for vast urban related applications, analyses and simulations. Large amount of 3D city models are created using various sources of data. Substantial studies are carried out for above-surface features in 3D city models. This ensures providing relevant information about various spatial analyses over the urban systems and environment. Relevant researches explored the numerous applications of 3D GIS such as disaster management, city administration, urban and environment planning, environmental studies, etc. Utility infrastructures (overhead, subsurface or on-surface) play the critical role in the urban space; still they are not considered in 3D city models. OGC CityGML is acting well behind these applications by integrating the geographic information, semantics and the various interdependencies information with the 3D city model. Moreover, comparative studies over the existing network data models make Utility Network ADE as the perfect approach for data modelling. This research proposes the methodology for 3D semantic modelling of subsurface water supply network along with its various „subsurface, overhead and on-surface‟ utility network components with the help of OGC CityGML Utility Network ADE. This study is conducted for Dehradun area. As a result, semantically modelled utility network data is utilised for successful implementation of use cases such as 1) areas affected by utility failure; 2) street space affected by utility maintenance; and; 3) visualisation. These cases are investigated along with urban space.

Published: November 2018

Abstract. Remote sensing and Geographical Information System (GIS) through Earth Observation (EO) Satellites have become most important tools for many of the societal applications of day-to-day life, during the past few decades of the 21st century, and this need is rapidly increasing. Presently, EO payload (PLD) data from Polar Orbiting Indian Remote Sensing (IRS) Satellite Missions is received at the Integrated Multi-mission Ground segment for Earth Observation Satellites (IMGEOS) at NRSC, Hyderabad, India. But at this geographical location, only four out of fourteen orbits data can be acquired from each of the polar satellites. These polar satellite orbits converge at poles, hence establishing a ground station at Polar Regions has an advantage of acquiring data from ten to twelve orbits.To increase the capability, a data reception Ground Station and Communication facility was established by ISRO at Bharati Station, Antarctica, located at 69° South and 76° East, in 2012–2013 (Austral Summer). This station is maintained for flawless operations and smooth flow of IRS Satellites EO data from Antarctica, by three Scientists/Engineers from ISRO, who overwinter at Antarctica, along with other Expedition members, by clearing the pre-requisites for an Antarctica Expedition. While this location is suitable to establish a Ground Station, the local conditions are a challenge to be faced (when established then, and now) to operate and maintain it 24 × 7 throughout the year.

Published: November 2018

Abstract. The crop suitability is the process of assessing the appropriateness or ability of a given type of land on the basis of growing conditions of a particular crop. The study focused on the crop suitability analysis of cereal crops for their production in Uttar Pradesh. Information about crop suitability is essential for proper management of agriculture in the study area. Remote sensing and GIS data provide a reliable information and technique to find suitable land for crops. The research was based on GIS based Multi-Criteria Decision Approach. The AMSR-2 (Advance Microwave Scanning Radiometer) soil moisture data, Carto-DEM, soil chemical and physical properties and climate data were used to identify the crop suitability in the study area. Weightage of different factors was arrived at based on input and feedback from experts. An Analytical Hierarchical Process (AHP) was used in ArcGIS environment to generate suitability map for the cereals crop. The suitability map has been categorised in the form of highly suitable, moderately suitable, low suitable and non-agricultural/ non-suitable region of the study area for Wheat, Rice, Sorghum, Maize and Pearl Millet/Bajra.The overall study indicates that the study area has a huge potential of cereal crop production. Therefore, improved levels of agricultural production can be achieved by cultivating crop in highly and moderately suitable areas; and practicing diversification of marginally suitable areas to crops other than that for which it is low suitable.

Abstract. Urbanization increases the pressure on land and ground water. Due to pressure on land and over extraction of the ground water for modernization and development, deformation of land increase. The traditional deformation monitoring techniques are costly and time taking. The Differential Interferometry Technique (DInSAR) has capability to monitor regional scale deformation. Recently Vasundra region of the NCR has experienced a road subsidence near to the multiple stories building. In the study we have attempted to identify the Vasundra and nearby region by the DInSAR technology to identify the deformation in Delhi and NCR focused on the Vasundra area of Ghaziabad, Uttar Pradesh, India. This is one of the developed and planned area in the Ghaziabad District. The Sentinel-1 C data has been used to monitor the deformation in that area. The Vasundra area has been deformed due to heavy rainfall and water logging in the surrounding area by which the road has been subsided up to 30 feet. Using the sentinel data we were able to identify the subsidence in Vasundra and nearby areas. Since the Sentinel scene was very big so a clear picture of the deformation indication in the NCR region are found which need more in-depth study further. Conclusively it can be said that DInSAR technique with Microwave data is a competent tool to monitor the minute deformation.

Abstract. The Himalayan region has experienced a number of large magnitude earthquakes in the past. Seismicity is mainly due to tectonic activity along the thrust faults that trend parallel to the Himalayan mountain belt. In order to study the ongoing tectonic process, we report Global Positioning System (GPS) measurements of crustal deformation in the Garhwal-Kumaun Himalaya through two continuous and 21 campaign stations. We collect GPS data since 2013 and analyze with the GAMIT/GLOBK suite of postprocessing software. Our estimated surface velocities in ITRF2008, India-fixed, and Eurasia-fixed reference frame lie in the range of 42–52 mm/yr, 1–6 mm/yr, and 31–37 mm/yr, respectively. We observe insignificant slip rate (∼ 1 mm/yr) of HFT that indicates its locking behavior. The slip rates of MBT and MCT, however, are consistent with the seismic activity of the study region.

Published: November 2018

Abstract. In the present study, an attempt is made to understand the impact on Social Vulnerability of the Kopili basin due to various severities of flood hazard. The flood hazard is generated using multi-temporal historical satellite based analysis and integration of annual flood inundation layers. The census of India data of 2001 and 2011 is spatially joined with village database to study the impact at village level. Using 5 Census variables from both Census 2001 & 2011 as vulnerability indicators, the Social Vulnerability Index (SVI) is derived and classified into various vulnerable zones namely Low, Moderate and High Vulnerable zones. The findings of the study show that the number of villages falling in Low and High Vulnerable zones had decreased during Census 2011 when compared to 2001 and a rise of 6% in villages falling in moderate vulnerable zones during 2011 is observed. The spatial database generated is useful to understand the impact of floods on the Social Vulnerability status of the basin and can be a useful input to further study the Physical, Economic and Environmental Vulnerabilities of the basin.

Abstract. This study aims to evaluate the effect of underground coal mining subsidence on the growth of native vegetation. For this study, an underground coal mine of South Eastern Coalfields Limited (SECL), India was selected. Changes in vegetation indices were analyzed using three remote sensing data of the previous five years. Three period’s Landsat 8 OLI resolution image data were used to calculate Normalized Difference Vegetation Index (NDVI) of the years 2014, 2016 and 2018 in QGIS environment. The study showed that the local grassland and forest were affected by the mining exploitation and subsidence but those effects were not significant to have an adverse impact on the same. The short-term mining was having an impact on the vegetation growth but the effects gradually disappeared with the gradual stabilization of the subsided land and in absence of human interference, vegetation recovered well. In long-term, subsidence was not having a major impact on the vegetation growth. Thus, coal resources exploitation and subsidence of the said mine of SECL did not bring out an adverse impact on a wide range of forest and grassland ecosystems, and these ecosystems could carry the partial destruction and ultimately stabilized ecosystems by self-repair.

Abstract. Geospatial technology is adopted in India through ‘Digital India’, for better governance and socio-economic benefits of common citizens. Remote sensing imageries and derived products are a direct input for geospatial data generation, monitoring resources and providing citizen services. As Indian Space Research Organisation (ISRO) is responsible for technology development, launch and data distribution of Indian remote sensing satellites, there is a conscious effort for partnership development with international space agencies and Indian industries to fulfil this requirement. Simultaneously ISRO’s co-operation with government departments for geo-spatial data generation and utilization is taken as a priority. This Paper presents the effort of ISRO for cooperation with International and national agencies as well as with government departments and policy makers. In this surge of utilization of geo-spatial techniques capacity building has become very relevant. A glimpse of geospatial education through government & academic institutes in India and E-learning is presented here with an emphasis of ISRO’s contribution.
RADIATIVE TRANSFER MODEL SIMULATIONS TO DETERMINE THE NIGHT TIME FOG DETECTION THRESHOLD
Authors: Gaurav S. , Jindal P.
Published: November 2018

Abstract. Every winter the Indo-Gangetic plains (IGP) of northern India are severely impacted both socially and economically by fog. For night time fog detection, visible imagery cannot be used. Also, as emissions from ground and fog is almost similar in thermal infrared (TIR, 10.8 μm) channel, TIR channel cannot help in identifying fog. However, emission in middle infrared (MIR, 3.9 μm) channel is less than emission in TIR channel over foggy area. Therefore, brightness temperature difference (BTD) between TIR and MIR is positive during night time over fog area. This BTD technique cannot be directly used during day time as MIR channel is contaminated by solar radiations. In the present work, a spectral sensitivity analysis study has been done for these two spectral channels using radiative transfer model (RTM) simulations to determine a threshold BTD for night time fog detection. SBDART (Santa Barbara DISORT Radiative Transfer) model was used for this study to simulate brightness temperatures (BT). The RTM simulations of BT of the two spectral channels was carried out for different fog microphysical characteristics like fog optical depth (FOD) and fog droplet size (Re). The fog episode of January 2018 over IGP was studied by applying threshold BTD obtained from simulation results for INSAT-3D data. A threshold BTD value > 5 K detected night time fog over IGP with good accuracy. The threshold BTD obtained from satellite image is compared with different cases established from simulation result which gave idea about microphysical properties of fog over IGP during winter seasons.

Authors: Sharma D. N. , Tare V.
Published: November 2018

Abstract. Estimation of evapotranspiration (ET) parameters is essential for understanding crop water requirements and to find out the ground water recharge. In situ data collection procedures are generally adopted to measure the parameters required to find ET. Latest remote sensing technologies accompanied by newly launched satellite datasets can supplement the field data collection and analysis by finding out some of the parameters such as land surface temperature, normalized difference vegetation index (NDVI), albedo, emissivity, etc. The Upper Ganga Canal Command Area (UGC) lying between two rivers Ganga and Yamuna situated between two states, namely Uttarakhand and Uttar Pradesh in North India is selected as the study area for this research work. Operational Simplified Surface Energy Balance (SSEBop) method is used to derive high resolution (10m) ET map for the Upper Ganga Canal Command Area. Sentinel-2 multi spectral images were used to derive land use, land cover (LU/LC) maps, NDVI, albedo, etc. Downscaled Landsat 8 images were used to derive land surface temperature of the command area. Meteorological data retrieved from the Indian Meteorological Department (IMD) was used to calculate reference evapotranspiration. ET map of the study area was generated using the above estimated parameters. Further, validation of the obtained ET values was accomplished by gridded ET data obtained from IMD.

Abstract. Most of the Indian remote sensing systems, provide sensors with one high spatial resolution panchromatic (PAN) and several multispectral (MS) bands. An increasing number of applications, such as feature detection, change monitoring, and land cover classification, often demand the use of images with both high spatial and high spectral resolution. Image fusion or pan sharpening, is a technique to enhance the spatial resolution. The most significant problem in the traditional fusion methods is spectral distortion of fused images. The main reason for this being, the physical spectral characteristic of the sensors are not considered during the fusion process, resulting in undesirable effects such as modified spectral signatures resulting in classification errors and resolution over injection. For most earth resource satellites which provide both PAN and MS bands, in ideal condition, all MS bands would be well separated and would cover exactly the same wavelengths as the PAN band. Theoretically, the measured energy in the PAN band can be obtained with the summation of corresponding MS bands. As the measured energy in an individual channel is the sum of incoming radiation and relative spectral response: Lk = L(λ) Rk(λ); where λ is the wavelength, the in-band radiance, L(λ) at aperture spectral radiance and Rk(λ) the peak-normalized spectral response. Therefore, the energy in PAN band can be estimated by defining weights as follows: Pan = wR R + wG G + wNIR NIR + other; where Pan, G, R, NIR represent the radiance of individual spectral bands wG, wR, wNIR are the weights of corresponding MS bands and other for the influence of the spectral range which is missing from MS bands but still covered with the PAN band. In this paper, a novel spectral preservation fusion method for remotely sensed images using Cartosat-1 PAN and Resourcesat-Liss4 Mx data is presented by considering the physical characteristics of the sensors. It is based on the curvelet transform using relative spectral response (RSR) values of the sensor, improved in two parts: 1) the construction of PAN image using RSR values and the curvelet components, 2) the injection method of detail information. The performance and efficiency of the proposed method is compared with traditional IHS, wavelet based methods both visually and quantitatively. The results show that the proposed method preserves spatial details and minimize spectral distortion.

Published: November 2018

Abstract. In the present study, a physics based method called Scheme for Atmospheric Correction of Landsat-8 (SACLS8) is developed for the Operational Land Imager (OLI) sensor of Landsat-8. The Second Simulation of the Satellite Signal in the Solar Spectrum Vector (6SV) radiative transfer model is used in the simulations to obtain the surface reflectance. The surface reflectance derived using the SACL8 scheme is validated with the in-situ measurements of surface reflectance carried out at the homogeneous desert site located in the Little Rann of Kutch, Gujarat, India. The results are also compared with Landsat-8 surface reflectance standard data product over the same site. The good agreement of results with high coefficient of determination (R2 > 0.94) and low root mean square error (of the order of 0.03) with in-situ measurement values as well as those obtained from the Landsat-8 surface reflectance data establishes a good performance of the SACLS8 scheme for the atmospheric correction of Landsat-8 dataset.
