Exponentiation is computing ge, where g is an element of a group G and e is a positive integer. In modular exponentiation the underlying group is ℤn or ℤ∗ n. This paper describe the methods to compute exponentiation where a fixed-exponent e is raised to several bases g of a group G. We describe modular exponentiation based on Bernstein's algorithm for multiplication by constant. We also present a modified approach to modular exponentiation based on k-ary String Replacement (SR(k)) representation.

Studies revealed that population of brown soft scale Coccus hesperidium was positively correlated with temperature and moisture. Maximum infestation was observed in the month of May whereas minimum was in December. Cymbidium hookerionum, C. longifolium and C. mastonon species harbored negligible scale insect population and performed well in the agroclimatic condition of Uttarakhand whereas C. eburneum species showed poor performance due to severe scale infestation.

A study was conducted to utilize the apple pomace for manufacturing an edible and nutritious bakery product. Biscuits were prepared utilizing apple pomace and were incorporated with black soybean for further nutritional enrichment. Biscuits were analyzed for physical, rheological, chemical and sensory parameters. Results showed that quantity of apple pomace significantly affected % spread factor, hardness and fracturability and quantity of soy flour significantly affected all the four factors (apple pomace/soy flour/apple pomace: soy flour, baking powder, ammonium bicarbonate and sodium bicarbonate) in apple pomace and soy flour biscuits respectively. Quantity of apple pomace: soy flour affected spread factor and overall acceptability. Spread factor increased and overall acceptability decreased with increase in the levels of apple pomace, soy flour and apple pomace: soy flour. Hardness increased with increase in apple pomace and soy flour levels in apple pomace and soy flour biscuits respectively. The sensory score on 9-point hedonic scale ranged from 5.6 to 8.8, 6 to 9 and 6 to 8.9 for apple pomace, soy flour and apple pomace: soy flour biscuits respectively indicating the acceptability of apple pomace: soy flour biscuits. Study revealed that instead of allowing apple pomace to get waste, it could be utilized in manufacturing the value added products by incorporation of back soybean flour.

To understand the impact of various tree barks (pine bark, oak bark and Rhododendron) as a component of potting mixture on flowering size plants of five species of Cymbidium (C. longifolium, C. hookerianum, C. elegans, C. mastersii and C. gigantium), a five year trial was conducted. Results showed significant improvement in number of shoots/ pot, height of plants at the time of flowering, plant fresh weight and dry weight, leaf number & length at six month and at flower emergence in all cymbidium species on pine bark potting mixture. Plant grown in pine bark containing potting mixture produced maximum number of spikes/plant and spikes/clump.

Apis cerana carana was found at all the selected altitudes i.e 500 msl - 2500 msl. Maximum numbers of bee hives were observed at 1600 - 2000 msl followed by lower altitude 1000 - 1500 msl. Highest and lowest elevations have low bee population. Distribution of honey bee at various elevations indicated that more than 75 per cent bee fauna was found in the range of 1000 - 2000 msl. Area under temperate fruits cultivation i.e. apple, pear, peach, apricot, almond and malta harbored highest percentage of honeybee population (43.57 per cent) followed by the area of higher river valley agroecosystem (31.45 per cent) where sarso, raye, lemon, coriander and barbery constituted the major bee flora. Forest fire plays important role in inhibiting the honey bee population in low river ally areas. Majority of area is occupied by thick pine forest solely suffered by forest fire in summers. In contrast at highest elevation (above 2500 msl) with the area frequently covered with mist accompanied by low temperature, the bee population is low and flowering period is short.

Small vegetative parts of Aconitum balfourii from different growth stages were excised for in vitro establishment. The callus induction was achieved from cultured leaf segment on MS medium fortified with NAA (2.5 mg/1) and BAP (1 mg/1). Calli upon transfer onto MS medium containing BA alone (0.5-4 mg/l) for shoot regeneration, multiplication and elongation. Up to 25 shoots per culture flask were obtained on 2 mg/l BAP after 7-8 weeks of culture. The optimum rooting on micro-shoots was observed on MS supplemented with IAA (1.8 mg/l). The in vitro developed plantlets with elongated roots were then subjected for further ex vitro rooting, acclimatization and hardening.

Disk scheduling is responsibility of operating system. To achieve this, it is required that disk drives should have fast access time and bandwidth. To improve both access time and bandwidth we need to schedule the servicing of disk I/O Request in efficient way. There are various Algorithm proposed previously for Disk scheduling. With any scheduling algorithms, performance depends heavily on the number and types of requests. For example suppose there is only one request to serve, then all algorithms are force to behave like FCFS. For every scheduling algorithm, we calculate head movement. Algorithm giving least head movement is better for a given list of request. This paper presents a new algorithm giving least head movement and is basically a modification over C-Look scheduling algorithm. © 2015 IEEE.

In the present investigation, statistical experimental design was used to optimize pretreatment parameters such as alkali concentration, solid to liquid ratio, temperature, and time period of treatment to achieve the highest saccharification yield using poplar biomass. A maximum saccharification rate of 41.5% was obtained after optimization of the pretreatment condition. The optimal alkali treatment conditions for poplar wood were found to be 2.8% NaOH with ratio of 1:8 at 94 °C for 60. min. The results of a confirmation experiment under the optimum conditions agreed well with model predictions. The physicochemical changes in substrate after alkali treatment were evaluated by Fourier transmission infrared spectroscopic analysis and scanning electron microscopy. Fourier transmission infrared spectroscopic results showed that alkali treatment removed large fractions of lignin. Scanning electron micrograph revealed the pores and cracks developed during pretreatment. © 2012 Elsevier B.V.
