  • Yield and Nitrogen Uptake in Wheat and Chickpea Grown Under Elevated
           Carbon Dioxide Level
    • Abstract: Increase in the atmospheric carbon dioxide (CO2) concentration has fertilization effect on crops if nutrient supply remains adequate. Response of cereals and legumes to increased CO2 concentration might differ due to the nitrogen fixing ability of leguminous crops. Considering the importance of differential response of cereal and legumes under elevated CO2 concentration, a field study was conducted to compare the effect of elevated CO2 on yield and plant nitrogen uptake in wheat and chickpea crop. Elevated CO2 level (550 ppm) increased yield by 15.1% and 16.7% over ambient in wheat and by 21.1% and 21.9% in chickpea (p ≤ 0.05) during the first and second years of the study. Nitrogen content in wheat grains decreased under elevated CO2 concentration. Chickpea, being a leguminous crop, showed no change in grain N content. However, higher biomass and grain yield resulted in higher N uptake in both the crops under elevated CO2 level. Under elevated CO2 concentration more partitioning of biomass toward seeds lead to higher seed N partitioning in chickpea. The study showed that although growth and yield of crops might increase in high CO2 condition, nitrogen concentration in grains and soil available N status might decrease in cereals like wheat. But chickpea might not get affected due to their ability to fix atmospheric N2.

  • Promethee Based Distributed Multihead Energy and Coverage Preserving
           Clustering Algorithm for Mobile Sensor Nodes
    • Abstract: In this paper, a preference ranking organization method for enrichment evaluations (PROMETHEE) based distributed multihead energy and coverage preserving clustering algorithm for mobile sensor nodes (PDMECCA) is proposed. The objective of proposed PDMECCA is to equally distribute the load (communication, computation) among Mobile Sensor Nodes using the multihead concept for balancing the energy consumption among nodes and increase the lifetime of network with the ability to persistently provide coverage and connectivity of the entire monitored area. This paper considers PROMETHEE method for optimal selection of cluster heads based on multi criteria. The results of simulation show that proposed algorithm effectively prolongs the network lifetime and provide constant coverage persistently.

  • Exploring the Potential of DNA/RNA Aptamers in National Security
    • Abstract: Internal security of nations has become a lot more fluid and prone to unconventional threats, post-cold war. For early threat detection and mitigation, rapid, reliable and simple solutions are needed. Nucleic acid aptamers, as a part of new and emerging branch of biotechnology, offer one of the possible solutions. Nucleic acid aptamers are single-stranded DNA or RNA sequences that assume a specific conformation depending on their base pair sequences and tertiary folding. Conformation thus assumed by the aptamer is unique and can bind to complementary ligands via non-covalent bonds. The aptamers can bind to ligands, which range from small molecules to entire cells. However, here, chemicals of interest are those, which pose a security concern, e.g., explosives, narcotics and chemical warfare agents. Aptamers are both resistant to environmental extremes and are cheap in mass production. These properties make aptamers of interest in the field for threat detection and mitigation in national security. Therefore, it is of utmost importance that challenges involved in translation of this technology from the laboratory to the field be addressed as soon as possible, to realize the benefits of this technology for defense applications.

  • Highly Negative Dispersion Nanocore Spiral Photonic Crystal Fiber for
           Supercontinuum Generation
    • Abstract: In this letter, a spiral shape photonic crystal fiber (S-PCF) with nanocore has been suggested for the generation of the supercontinuum. The designing parameters have reformed to optimize the optical properties of the proposed structure. Finite element method is utilized to perform the numerical analysis of the proposed S-PCF. The proposed S-PCF exhibits a highly negative dispersion which ranges from − 82.21 to − 213.90 ps/(nm km) and high nonlinearity in the order of 6.31 × 107 W−1 km−1 at the 1.55 µm wavelength. The birefringence of the proposed structure is zero at the 1.55 µm wavelength. Besides, effective area and field distribution are also described briefly.

  • Passenger Car Active Suspension System Model for Better Dynamic
           Characteristics
    • Abstract: The technological investigations to a light passenger car have been carried out in order to improve the comfort and safety features by the implementation of an active suspension system. A fuzzy logic control-based active suspension system is proposed for the fuel-efficient small passenger cars to fulfil the design upgradation requirements. The proposed design comprised of hydraulically powered actuators is installed at each of the car wheels between sprung and unsprung mass to compensate the ground forces in order to resolve the instability and comfort issues. The dynamic analysis figures out the significant improvement of 12% in comfort and 11.53% in the car stability.

  • Reducing Reconfiguration Overheads Using Configuration Prefetch, Optimal
           Reuse, and Optimal Memory Mapping
    • Abstract: Modern embedded systems are packed with dedicated field-programmable gate arrays (FPGAs) to accelerate the overall system performance. But the main drawback in using FPGA as a reconfigurable system is that a lot of reconfiguration overheads are generated in the reconfiguration process. The reconfiguration overheads are mainly because of the configuration data being fetched from the off-chip memory and also due to the improper management of tasks during execution. This work focusses mainly on the prefetch heuristics, reuse technique, and the available memory hierarchy to provide an efficient management of tasks over the available resources. This short communication proposes a new optimal replacement policy which reduces the overall time and energy reconfiguration overheads for static systems in their subsequent iterations. It is evident from the results that most of the time and energy reconfiguration overheads are eliminated.

  • An Efficient Hybrid User Profile Based Web Search Personalization Through
           Semantic Crawler
    • Abstract: The World Wide Web has a collection of trillions of web pages and these web pages are increasing day by day. Web pages available on the Web change frequently and these changes are sometimes unnoticeable by the end user. The exponential growth of web documents on the Internet makes it difficult to find out which are the most relevant web documents for a particular end user on a given search query and user spends a lot of time to get relevant information. The proposed web search personalization system successfully identifies preferences of the end user and constructs an efficient user profile for every end user. It utilizes the built web page repository by retrieving web search results and personalizes them according to user preferences. It is also capable to handle ambiguous queries. The proposed system increases the search accuracy by 37.6% over existing agent based personalization system.

  • A Scientific Note on Occurrence and Infestation of Jewel Beetle Belionota
           Prasina (Coleoptera: Buprestidae) on Cashew ( Anacardium Occidentale )
    • Abstract: The occurrence of Jewel beetle Belionota prasina (Thunberg, 1789) (Coleoptera: Buprestidae) infestation on cashew from Goa, India was reported in this communication. Most of the infested trees were previously attacked by stem borers. Semi-circular D-shaped exit bore holes measuring 7–10 mm in length and 4–7 mm in width were found along the main trunk and branches. Adult beetles were dark greenish blue in colour and measured about 21–28 mm in length. Grubs were fleshy, whitish yellow in colour and measured 9–50 mm in length. Various stages of grub were observed on the infested trees. Pre-pupa and pupa were yellowish white in colour and measures 26–32 mm and 20–23 mm in length, respectively. Maximum of 132 grubs, 8 pre-pupae, 22 pupae and 61 adults were collected from a single affected tree. An average of 55.8 grubs were found to be feeding on a single tree and could successfully complete the life cycle on a fresh cashew log. Thus, cashew could be a new host plant for grubs of this buprestid, Belionota prasina.

  • Assessment of Genetic Diversity and Evaluation of Relatedness Through
           Morphological and Molecular Markers Among Medicinally Important Trees:
           Terminalia arjuna , T. bellerica , T. catappa and T. chebula
    • Abstract: Terminalia trees are being over exploited because of their medicinal and economical importance leading to loss of valuable genetic resources. The study included morphological variation and characterization of genetic diversity at interspecific level. Genus Terminalia is a complex group having many problems associated with taxonomic identification. Morphologically T. arjuna can be distinguished from other species having winged fruits whereas the fruits of T. catappa are elliptical and tomentose. Fruits of T. chebula are provided with ribs while fruits of T. bellerica are without ribs. Thus different species of Terminalia can be distinguished by characteristic of fruits and sometimes by characteristic of leaves. For the first time comprehensive study was done for estimation and analysis of genetic variation through random amplified polymorphic DNA (RAPD) and inter-simple sequence repeats (ISSR) markers. A total of 12 polymorphic primers (6 RAPD and 6 ISSR) produced 80 polymorphic bands with an average of 7.5 bands per primer. The average polymorphism was 87.97% and five primers were reported to produce 100% polymorphism. Dendrogram based on RAPD and ISSR data grouped four Terminalia species in two distinct clusters. Cluster-I comprised 2 species viz. T. arjuna, T. chebula, while cluster-II comprised two species T. bellerica and T. catappa. Clustering of species was altercating with previous morphological studies.

The generation time (Tc), the net reproductive rate (R0), the intrinsic rate of natural increase (rm) and the finite rate of increase (λ), were respectively, 47.36 days, 644.64, 0.13 and 1.14, which are comparable to the findings made on the P. acuta in other parts of the world. Variations in the life history of P. acuta may be possible if considered over the newly invaded habitats in West Bengal, India. Although the snails are restricted to the sewage drain habitats, in Kolkata, India, the results are indicative of the prospective invasion of the snails to other freshwater habitats, if appropriate measures to control the population are not adopted.

  • Angiosperm Phylogeny Group Classification in Fourth Iteration: Its Future
           Impact in India
    • Abstract: The communication discusses major changes in the new version of APG classification and its adoption in India. APG IV has further stabilized with addition of 2 informal groups, 5 new orders, 10 new families, re-circumscription of 20 earlier families and reduction in number of unplaced taxa. A comparison of APG versions with 4 recent individual classifications proves it more stable. A circle-in-circle diagram and a simplified cladogram of the classification are devised to make it easy to understand. Adoption of APG IV is visible in the world but Indian taxonomic institutions are sceptical for its changing nature. In a country where Linnaean Taxonomy is dominant, species richness is high, flora is incompletely explored and published, adoption of APG classification in flora or herbaria will jeopardize the progress. It seems that morphological taxonomy will remain dominant and APG IV will be mainly a topic of classroom teaching in India.

  • Seabuckthorn: Opportunities and Challenges in Ladakh
    • Abstract: Ladakh covers around 70% area of Jammu and Kashmir and houses diverse groups of medicinally important plants. One of these plants is Seabuckthorn. A storehouse of innumerable health promoting substances, this plant has assumed immense significance for the past decade or so. Despite being a dominant inhabitant of Ladakh and covering around 11,500 ha of land, it is used to a limited extent by the local populace. These uses are deep rooted traditionally and are not known to all. Surveys were carried out in different villages of Leh and Kargil districts of Ladakh region to record data and collect information on the ethno botanical usage of Seabuckthorn. The paper discusses the indigenous uses of this medicinal plant vis-a-vis its potential for sustainable utilization, which is not realized to the fullest.
