Abstract: Studies from different parts of the world have generated evidences of the effects of climate change on phenology and persistence of species. However, datasets or evidences are lacking for majority of the regions and species, including the climate-sensitive Himalayan biodiversity hotspot. Recognizing this gap in the information and realizing wide-ranging implications of such datasets, the present study generates evidences of changes in flowering phenology of an important tree species, Rhododendron arboreum in Indian central Himalaya. Real-time field observations (2009-2011) showed peak flowering during early February to mid-March. Analysis on long-term temperature data revealed significant (P<0.01) increase in seasonal (winter and post-monsoon) and annual mean maximum temperature. Generalized additive model (GAM) using real-time field observations (2009-2011) and herbarium records (1893-2003) predicted 88-97 days early flowering over the last 100 years. Furthermore, GAM using long-term temperature data, real-time field observations and herbarium records depicted annual mean maximum temperature responsible for shifts in flowering dates of the target species. The study provides an important insight of species response to climate change in the Indian central Himalaya and highlights the need for further research on the subject to improve our understanding of the effects of climate change on species and consequently on ecology of the region.

Keywords: Dioecy, floral biology, pollination efficiency, sea buckthorn, wind pollination.
Abstract: Fruits of Hippophae rhamnoides (Elaeagnaceae), commonly known as sea buckthorn or Leh-berry in India, constitute an important source for many medicinal and nutritional products. As the species is of high economic value, attempts are being made to establish commercial plantations for a sustainable supply. There is hardly any information on pollination ecology of this species, which is necessary for establishing and managing commercial plantations. We studied the floral biology and pollination ecology in natural populations of the species growing at Leh-Ladakh. H. rhamnoides is dioecious and exclusively wind-pollinated. The male flowers produce an enormous amount of dry, powdery pollen grains that remain viable for up to 48 h. The pollen flow in the air from the source is confined to 15 m. The female flowers are uniovulate. In nature, about 60% of the female flowers get pollinated with an average stigmatic pollen load (?SE) of 9.49?0.76. For optimal plantation conditions, it is suggested that a male plant must be inter-planted within 10-15 m of the female plants for effective natural pollination.

Keywords: Geochemical studies, granitic melt, pegmatites, subduction
Abstract: On the basis of geochemical studies, pegmatites emplaced in the Rajgarh Group of Delhi Supergroup in the South Delhi Fold Belt have been classified in to three groups. They show a variety of rare earth element enrichment patterns, LREE/HREE values and Eu anomalies. The geochemical affinities of these pegmatites suggest their calc-alkaline nature, volcanic arc granite signature in tectonic discrimination diagrams (Nb vs Y and Rb vs Nb+Y) and a probable S-type parentage as inferred from their high A/ CNK value, peraluminous character, presence of high normative corundum and abundance of garnet and muscovite. These features have been related to subduction-related processes which might have generated the parent granitic melt forming these pegmatites.

Keywords: Bactrocera dorsalis, climate change, geographical distribution, Oriental fruit fly.
Abstract: An attempt was made to understand the influence of climate change on future potential distribution of Oriental fruit fly (OFF), Bactrocera dorsalis (Hendel), a polyphagous pest on a wide variety of fruit crops in India. Prediction of the potential distribution of OFF was done for different time-frames (2030, 2050, 2070, and 2090) under the A1B climate change scenario (CSIRO-Mk3.0, a global climate model) using CLIMEX software. The model predicted an overall gradual decrease in terms of area suitability for OFF in India by 2090 due to increase in various stress factors to the pest. In temperate regions of the north and northeastern parts, incidence of the pest may increase due to rise in temperature coupled with decrease in cold stress. In North India, the model predicts the regions of Jammu & Kashmir, Himachal Pradesh, Uttarakhand, Haryana and Punjab to be more climatically suitable for OFF by 2030 and there is an expected steady increase in suitability by 2050, 2070 and 2090. The CSIRO model for North East indicated that by 2090, Assam, Arunachal Pradesh and Manipur would become highly suitable for the pest. The projected range expansion in terms of area suitability was recorded up to 100 km in temperate regions. Central and western India are projected to become progressively less suitable by 2030, 2050 and totally unsuitable by 2090. In South India, there was slight reduction in climatic suitability for OFF in terms of ecoclimatic index over time-frames 2030, 2050, 2070, 2090 as highly suitable, optimal, suitable and marginally suitable respectively. Regression analysis was carried out using growth index obtained from CLIMEX and pest trap counts. Additionally, field level validation of the model was carried out for selected locations.

Abstract: In the fault-ridden, seismically and tectonically active belts recurrently ravaged by excessive rains and resultant landslides in the Uttarakhand, a very large number of big and small dams are being constructed and planned. Quite many of these projects suffered crippling damages during the 2013 disaster as mountain slopes slid down and floodwater severely eroded stream banks and dumped huge volumes of sediments on critical facilities. If the idea is to have environment-friendly power projects, then the planners and dam builders must not ignore the geological reality of the geodynamically sensitive region. Better sites for dams can be explored far upstream of the Main Central Thrust Zone.

Keywords: Higher education, I-distance method, university rankings, methodologies and indicators.
Abstract: Although the subject of ranking higher education institutions is frequently elaborated in many research papers, consensus about a leading ranking methodology has not been reached yet. Consequently, different methodologies are based on rather conflicting indicators and therefore often provide highly diverse rankings of the world ' s best universities. For instance, SCImago Institutions Rankings (SIR) methodology is exclusively based on indicators of scientific output, while Times Higher Education World University Rankings (THE) and Quacquarelli Symonds World University Rankings (QS) take into account the teaching dimension of the university performance to a large degree. To explore the impact of different methodologies further, we first obtained data on Asian best-ranked universities according to SIR, THE and QS methodologies. The aim of this article is to explore possibilities to enhance ranking methodologies using I-distance method. The result was manifold: first, by employing our I-distance approach we were able to point out potential weaknesses of subjectively chosen weighting factors of THE and QS ranking methodologies. Secondly, we were able to provide detailed information on how each QS and THE indicator contributes to the final rank and emphasize the crucial indicators in the process of ranking. Thirdly, SIR does not provide the total score and its appropriate rank; and using our approach not only did we provide the total score but also determined the relative significance of each compounding SIR indicator. One of the contributions lies in the use of the I-distance method, which can easily integrate variables with different measurement units into one composite indicator. Moreover, our approach could be a foundation for impartial framework of universities ' assessment, independent of subjectively formed weighting factors. Finally, a special overview of university performances of leading Indian universities is provided.

Abstract: Rifting between India, Antarctica and Africa during break-up of the eastern Gondwanaland, led to the generation of many basins along the Eastern Continental Margin of India, with Cauvery Basin, Tamil Nadu being the southernmost of all basins. Sivaganga Formation, directly overlying the Archean basement, represents the first episode of Cretaceous sedimentation in the Cauvery Basin. It has been noted that the sedimentation in the Early Cretaceous Sivaganga Formation commenced with the deposition of fluvial coarse clastics (conglomerates and sandstones) in the early rift stage; and as the rifting progressed, marine influence increased and the deposition of finer clastics (sandy clays and clay-stones ) took place. These syn-rift sediments are overlain by thick, post-rift, Middle to Late Cretaceous marine mixed siliciclastic-carbonate sequence.

Abstract: A growing body of evidence clearly indicates that climate change is a major driver of ecosystem change and alter the structural and functional attributes of various systems. However, it is unclear that how above-and belowground parts will respond to climate change. Therefore, majority of the ecosystem models could not consider key variables modulating above-and belowground responses while modelling ecosystem response to climate change. Here we discuss the integrating above-and below ground responses to climate change so that it would be helpful for ecosystem modelling and predicting their response to climate change.

Keywords: Dominant markers, genetic diversity, Pongamia accessions.
Abstract: The extent of genetic diversity was assessed in 12 Pongamia accession from different regions of Delhi and surrounding areas using two dominant markers, namely ISSR and three endonuclease AFLP (TE-AFLP). Five ISSR primers and two TE-AFLP primer combinations generated a total of 12 and 48 polymorphic bands respectively. The Jaccard ' s dissimilarity coefficient ranged from 0 to 0.90 for ISSR and from 0 to 0.67 for TE-AFLP markers. The polymorphic information content of both markers was equal. However, TE-AFLP had much higher values of marker index and resolving power compared to those obtained for ISSR markers. This study demonstrates the usefulness of dominant markers like ISSR and TE-AFLP for assessment of genetic diversity in Pongamia for which microsatellites markers are still not available. However, high multiplex ratio, easy scorability and other high band attributes of TE-AFLP markers make them more suitable compared to ISSR for genetic diversity analysis.

Abstract: Total ring width (TRW) and earlywood width (ERW) of fir (Abies Pindrow) compared to latewood width (LRW) are strongly correlated with Palmer Drought Severity Index (PDSI) during summer season (March to October). Correlation coefficients for the period 1876-1948 between PDSI and TRW as well as ERW are 0.43 and 0.50 respectively, which is found to be significant at 0.01% level. Thereafter, their relationship weakened as temperature changed over the region, whereas maximum latewood density (MXD) reveals significant negative association with PDSI during summer season. Moreover, monthly mean, maximum and minimum temperatures during August to September of the region indicate significant positive response with mean, maximum and minimum temperatures are 0.60, 0.61 and 0.51 respectively, which is significant at 0.01% level. There is also high temporal stability in the relationship between MXD and temperature from 1916 onwards over the region.

Abstract: A low-cost accident detection system utilizing cheap ADXL345 accelerometers and GPS receiver is proposed in this communication. The accident detection algorithm was developed based on sudden deceleration. The double integration of the acceleration and heading from the tilt angles of accelerometers were used to determine the location. Kalman filter was utilized to correct the accumulated double integration errors with the trusted GPS data. The field tests demonstrated the correct functioning of the accident detection algorithm and location. The proposed low-cost system can save many lives by the automated accident detection and accurate location even during GPS outage.

Keywords: Fly ash, concrete composite, mechanical property, nano-SiO?, steel fibre.
Abstract: A parametric experimental study has been conducted to study the effect of nano-SiO? particles and steel fibres on the mechanical properties of the concrete composite containing fly ash. Five different nano-SiO? contents (1%, 3%, 5%, 7% and 9%) and five different steel fibre contents (0.5%, 1%, 1.5%, 2% and 2.5%) were used. The results indicate that addition of nano-SiO? and steel fibres decreases the slump and slump flow of the fresh concrete composite containing fly ash, and both the slump and slump flow decrease gradually with the increase in nano-SiO? improves the mechanical properties of concrete composites containing fly ash. There is an increase in the compressive strength and compressive modulus of elasticity with increase of nano-SiO? content when it is below 5%, while they begin to decrease after the nano-SiO? content is beyond 5%. Steel fibres help improve the mechanical properties of concrete composite containing fly ash and nano-particles. With the appropriate fibre content, the reinforcement of steel fibres on the compressive strength and compressive modulus of elasticity of the concrete composite becomes more obvious as the fibre content increases.

Abstract: This article presents a study of academic performance evaluation using soft computing techniques inspired by the successful application of K-means, fuzzy C-means (FCM), subtractive clustering (SC), hybrid subtractive clustering -adaptive neuro fuzzy inference system (SC-ANFIS) methods for solving academic performance evaluation problems. Modelling of students ' academic performance is a difficult optimization problem. We explore the applicability of K-means and FCM, SC, hybrid SC-FCM and SC-ANFIS clustering methods to the new student ' s allocation problem, which allocates new students into some classes that consist of similar students and the number of the students in each class not exceeding its maximum capacity. The models were combined with fuzzy logic techniques to analyse the students ' results. In this article, we have conducted clustering based computational experiments to analyse the effects of the different clustering algorithms like K-means, FCM, SC, hybrid SC-FCM and hybrid SC-ANFIS clustering methods for modeling students ' academic performance evaluation. Based on the comparison of the results, it is found that the hybrid SC-ANFIS clustering is better than the other methods.

Abstract: An effective scientometric analysis based on SCOPUS database was conducted to evaluate nano-biotechnology research from a different perspective for the period 2003-2012. Nanobiotechnology has been intensively investigated by bibliometric methods due to its technological importance and expected impacts on economic activity. The present study analyses nanobiotechnology research output during 2003-2012 on different parameters, including the growth, global publications share and citation impact, share of International collaborative papers and contributions of major collaborative partner countries. A total of 114,684 papers were published during 10 years, which received 2,503,795 citations with an average of 21.83 citations per paper. It has been observed that during 2003-2012, USA held the first position by number of publications (34,736), h-index (349), g-index (541), hg-index (434.52) and p-index (326.47). Developing countries such as India, China, South Korea and Canada showed increasing trends in their publications and their activity index also showed increasing trends. Top 10 Institutions contributed 7.16% share of total publications. Masssachusetts Institute of Technology, USA received the highest h-index (1200 among the top 10 institutions. Biomaterials (1631) was the top journal of publication output; Nano Letters had the highest impact with an average citation per paper (73.86) and American Chemical Society received the highest h-index (158) among the top 10 journals.
