Information Literacy is the defining paradigm of modern education. Librarianship in the present digital age is not restrained to the documents rather; the profession has now amalgamated to multifarious subfields. Information literacy is essential today for development and progress. This paper aims to attempt find the concept of information literacy (IL).The paper shows initially the general idea about information, information literacy with relation to library and information science. It describes the importance, components, basic types and needs of information literacy. The paper further gives a glimpse of different activities and roles especially information literate LIS professionals. This paper also highlights the emerging trends and developments of information literacy in the library profession in the present day.Keywords

Field experiment was conducted during May 2009 to April 2010 in tuberose cv. Prajwal to study the growth and yield as influenced by plant growth regulators and micronutrients in Factorial Randomized Block Design. The treatment comprised of dipping the bulbs in two growth regulators namely, GA3 @ 200 ppm for 12 h, CCC @ 5000 ppm for 1 h were given at planting and foliar spray of micronutrients namely, H3BO3 0.1 %, ZnSO4 0.5 % and FeSO4 0.2 % were applied either alone or in combinations on 60, 120, 180 and 240 days after sprouting. Observations were recorded on sprouting, growth, flowering and yield parameters. The results revealed that dipping of bulbs in GA3 @ 200 ppm for 12 hours recorded 100 per cent sprouting and early sprouting by 5 days over control (12.75 days). Dipping the bulbs in GA3 @ 200 ppm and foliar spray of all the micronutrients (B, Zn and Fe) recorded highest plant height (49.56 cm) at first spike emergence, total leaf area per clump (2317.20 cm2), spike length (100.59 cm), number of flowers per spike (45.74), improved flower length (7.24 cm), enhanced flower yield per hectare (16.24 t) and highest estimated net income of Rs. 6,44,444 per hectare. The dipping treatments with CCC@ 5000 ppm for 1 h significantly increased the number of leaves at first spike emergence (25.29), diameter of unopened flower bud (3.78 cm) and extended duration of flowering (21.38 days). The increase in yield is resulted by the assimilatory power of growth regulators and contributory role of all the micronutrients involved. Economic analysis also revealed that micronutrient sprays at 60, 120, 180 and 240 days after sprouting could be beneficial when dipping of bulbs in GA3 @ 200 ppm for 12 h and this will be quite profitable to the farmers cultivating in the marginal soils.Keywords

Cotton leafhopper, Amrasca biguttula biguttula (Ishida) (Hemiptera: Cicadellidae) is a major sucking insect pest of cotton in India. Indiscriminate use of pesticides has led to the development of resistance to most of the recommended pesticide groups. Though there are multiple mechanisms and principles of insecticide resistance development in insects, the gut bacterial-mediated degradation of insecticides is relatively less explored. In the present study, the gut bacteria of field-collected, insecticide-resistant population of A. biguttula biguttula were compared with a laboratory-reared susceptible population. Among the five culturable gut bacteria from the imidacloprid-resistant population, only Enterococcus silesiacus CLHG1a exhibited growth in the agar medium amended with 50 and 100 ppm of imidacloprid. The imidacloprid degrading capacity of E. silesiacus CLHG1a was further confirmed by HPLC analysis. E. silesiacus and Bacillus amyloliquefaciens CLHG2 showed higher esterolytic activity (0.348 and 0.309 mmoles/min/mg respectively). The esterase zymogram on native PAGE revealed a single major band. This study provides clear evidence that the bacterium E. silesiacus isolated from the gut of A. biguttula biguttula has the ability to degrade imidacloprid and may have played a role in the detoxification of pesticides.Keywords

A Synonym based document clustering approach is proposed to cluster more document related to the user query. The synonym of the word is got from online thesaurus. Document clustering is one of the concepts in data mining. Many techniques are used for clustering. In the existing synonyms of the word and their synonyms stored in the database by the user. User should store all the words one by one so it takes more time. Sometimes all the words could not be stored in the database. If the word has more than one synonym it will be complex. In this proposed synonyms are got from the thesaurus.com (online library). In this method both the user entered keyword and their synonyms also clustered. Tf-idf method is used for ranking the clustered documents by using c#.net code. So it gives more relevant and accurate results of the user query. For experimental purpose we have used some text files. It gives better performance than the existing method and there is no need to maintain the database.Keywords

A study was undertaken to characterize the granulosis viruses (GVs) of early shoot borer, Chilo infuscatellus (Snell.) (Crambidae: Lepidoptera) and internode borer, Chilo sacchariphagus indicus (Kapur) (Lepidoptera: Crambidae) in sugarcane. Scanning electron photomicrographs revealed ovo-cylindrical occlusion bodies (OBs) of GVs in early shoot and internode borers with an average size of 425.03 and 230.21 nm, 387.64 and 208.68 nm in length and breadth respectively. Transmission electron photomicrographs also showed ovo-cylindrical OBs embedded with a rod-shaped virion. The average length and breadth of the virion in the OB was 271.0 ´ 52.6 nm, 257.0 ´ 50.2 nm for early shoot and internode borer GVs respectively. Toxicity studies with the respective GVs revealed lethal concentration values of 4.38, 4.61, 6.89 OBs/mm2 and 1.85, 135.43, 8045.27 OBs/mm2 to second, third and fourth larval instars of Chilo infuscatellus granulosis virus (ChinGV) and Chilo sacchariphagus indicus granulosis virus (ChsaGV) respectively.Keywords

Genetic variability studies in tuberose were carried out among 5 varieties for 12 characters at Botanical gardens, Tamil Nadu Agricultural University, Coimbatore during the year 2011-2013. In genotypic and phenotypic levels, weight of florets per spike exhibited positive relationship with yield of florets per plot (4 × 1 m) (0.965) and number of spikes per m2 (0.534). Positive and significant association was also observed for number of spikes/ m2 with yield of florets per plot (4 × 1 m) (0.565). The maximum positive direct effect on number of spikes per m2 was contributed by weight of florets per spike (0.6378) followed by number of leaves per plant (0.5782), flowering duration (0.3756), rachis length (0.2779), days taken for sprouting of bulb (0.2580), length of the floret (0.2277) and days to spike emergence (0.0213). Hence, the characters viz., weight of florets per spike, number of leaves per plant, flowering duration, rachis length, days taken for sprouting of bulb, length of the floret and days to spike emergence had significant positive correlation co-efficients and positive direct effects on yield which formed reliable indices for selection of genotypes for yield.

Orthogonal Frequency-Division Multiplexing (OFDM) is a robust multi carrier modulation system most commonly used in many wireless communication standards. The overall OFDM system performance is stable over signal distortions caused by multipath fading channels but synchronization problems caused significant quality degradation at receiver side. In recent years many papers have been published to mitigate this synchronization problem still the overall system performance is getting worsened due error caused by fixed point model. In this paper we analyzed the limitations of the fixed point computations in timing and frequency offset estimation and its performance in terms of error rate. Here we carry out both analytical approach and statistical results obtained through extensive numerical simulations and the bit length of floating point IEEE 754 standard single precision formats is optimized with the required degree for an accurate offset estimation to reduce OFDM design complexity. Also, a unique floating point precision model for error less FFT computations for all mapping levels used in OFDM system. The proposed scaled floating point precision model is compared over full precision model and its efficiency against fixed point model in OFDM synchronization process is proved through MATLAB simulations. Finally through FPGA hardware synthesis the complexity reduction of proposed scaled precision model is proved in basic arithmetic models such as adder and multiplier against single precision format. Here we proved the resource utilization rate is reduced by half as compared to standard full precision models without compromising any quality degradations. The computational error free nature of proposed scaled precision model in both timing and frequency offset estimation process and its overall OFDM system performance in terms of BER rate is proved.Keywords

The present investigation was carried out to identify organic volatiles components present in Lantana leaves and found to exert biopesticidal-repellent action on many pests of horticultural crops. Volatile organic chemicals (VOCs) eluted from [Lantana camara var. aculeata (L.) Moldenke] was extracted ascrude oil and analysed by gas chromatography-mass spectrometry (GC-MS). A total of 10 to 15 volatile compounds present in ethanol and methanol extracts were identified. These compounds were found distributed in several chemical classes namely, alcohols, carbonyl compounds (ketones, aldehydes, and esters), fatty acids, terpenes, nitrogenous and sulphur compounds. Of these various classes of compounds identified,Phenol-2-methyl-5-(1,2,2- trimethylcyclopentyl) - (S)-(CAS)-10.36 per cent and 2-(p-Methylphenyl) benzimidazole-7.86 per cent constituted major groups accounting for ethanol and whereas sulphur compounds viz.,stigmast-5-en-3-ol, (3.beta.) 15.48 per cent, caryophyllene (7.63%) and phenol having 14.96 per cent constituted major groups in methanol extracts.Keywords

Fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) is an invasive insect pest of maize in India. Natural occurrence of nucleopolyhedrovirus (NPV) infection on S. frugiperda larvae was recorded in 2018 during surveys conducted in maize fields in Chikkaballapura district of Karnataka, and Coimbatore and Tirupattur districts of Tamil Nadu. A strain of S. frugiperda nucleopolyhedrovirus (SpfrNPV NBAIR1) infecting S. frugiperda was isolated from the diseased larvae; morphological and biological characteristics were studied. Electron microscopic studies showed tetrahedral-shaped SpfrNPV occlusion bodies (OBs) of size 1.64 μm. Dose–mortality bioassays revealed that first, second and third instar larvae were equally susceptible (LC50 3.71–5.02 OBs/mm2) to SpfrNPV infection. A PCR technique for detection of viral DNA in S. frugiperda NPV was developed by employing the polyhedrin gene (polh)-specific primers. The amplicon of 618 bp was amplified, sequenced and NCBI GenBank accession number was obtained (MT422725). Blast analysis revealed that SpfrNPV conserved polh gene sequence matched 100% with the reference GenBank sequence (J04333) from the NCBI database which confirmed the identity of the SpfrNPV.Keywords

Over the past decades, the evolution of new wireless technology has led to increased attention toward Smart Home Automation Systems (SHAS). In the smart home, numerous smart devices are interconnected with the proliferation of the Internet of Things (IoT) technology to provide users with a more comfortable lifestyle. Prior research on the smart home system has enacted machine learning and deep learning techniques to forecast the consecutive activities in the smart home. This research paper aims to enhance the future decision-making of energy consumption with the assistance of environmental factors and home appliances by exploiting the Tensorflow-based deep ensemble learning technique. The enhancement of future decision-making in smart home automation systems primarily involves the classification of energy consumption levels from the knowledge of external environmental factors and energy consumption levels of home appliances through the phases of data preprocessing, feature selection, fuzzy logic-based data labeling, and finally, classification of energy consumption using TensorFlow based deep ensemble learning technique. The data obtained from the effective feature selection technique is subjected to labeling via the fuzzy logic system to classify the energy consumption of smart home appliances. Finally, this work classifies the level of energy consumption based on the labeled knowledge of smart home data using a tensorflow-based deep ensemble learning model. The experimental model implements the proposed deep ensemble learning model in the tensorflow framework, which improves the decision-making performance of energy utilization in the smart home system. Experimental results illustrate that the proposed deep ensemble learning model yields superior classification performance than the other baseline classifiers, such as Artificial Neural Network (ANN), Convolutional Neural Network (CNN), and Long Short-Term Memory (LSTM) on the smart home dataset.Keywords
