. V. N. Ramesh,B. Naresh Kumar Reddy,V. V. Murali Krishna,B. M. Kumar Gandhi,V. Shiva,M. Dronika Devi 보안공학연구지원센터 2015 International Journal of Smart Home Vol.9 No.3
Now a days Jobs are Scheduled in a single processor or more than one processor, a real time job is scheduled or executed based on requirements, An Successful task in embedded system ought to have constrained asset necessities: Memory, execution time and power utilization, these necessity are not generally simple to fulfil in real-time embedded system with hard task deadlines. In this paper we explore the effective time utilization, without influencing the deadline requirements of typical hard real time task ,there are no limitation on the new results each task can be periodic or sporadic ,with relative deadline which can be less than ,equivalent to or greater than its period, it is too fast , best-effort ,effective real time scheduling algorithm for a wide variety of job parameters.

Complex synergistic interplay of the composite mixture of compounds present in plants may be the reason of their beneficial effects. In this perspective an important yet not well studied ethnomedicinal plant Lasiosiphon glaucus was subjected to invitro anticancer analysis. The flowcytometry study revealed that the plant has cytotoxic effect against breast cancer cells (MCF-7) acting upon multiple pathways, inhibiting cell proliferation (Downregulation of Bcl2 and Akt) and inducing apoptosis (Mitochondrial membrane depolarisation, Upregulation of p53, caspase 8, caspases 3 and DNA fragmentation). It is interesting that the plant activated both intrinsic and extrinsic pathways while inhibiting cancer cell proliferation. The study, a first report, highlights the use of L. glaucus in ethnomedicine for treating cancer.
Compaction and strength behavior of lime-coir fiber treated Black Cotton soil
Ramesh, H.N.,Manoj Krishna, K.V.,Mamatha, H.V. Techno-Press 2010 Geomechanics & engineering Vol.2 No.1
This paper describes the compaction and strength behavior of black cotton soil (BC soil) reinforced with coir fibers. Coir used in this study is processed fiber from the husk of coconuts. BC soil reinforced with coir fiber shows only marginal increase in the strength of soil, inhibiting its use for ground improvement. In order to further increase the strength of the soil-coir fiber combination, optimum percentage of 4% of lime is added. The effect of aspect ratio, percentage fiber on the behavior of the composite soil specimen with curing is isolated and studied. It is found that strength properties of optimum combination of BC soil-lime specimens reinforced with coir fibers is appreciably better than untreated BC soil or BC soil alone with coir fiber. Lime treatment in BC soil improves strength but it imparts brittleness in soil specimen. BC soil treated with 4% lime and reinforced with coir fiber shows ductility behavior before and after failure. An optimum fiber content of 1% (by weight) with aspect ratio of 20 for fiber was recommended for strengthening BC soil.

Dhanya S.,Ramesh N V,Abhayakumar Mishra 한국식품연구원 2019 Journal of Ethnic Foods Vol.6 No.-
Ayurveda (the science of life) is one of the branches of Vedas. It is regarded as upaveda of Atharva Veda. It is a steam of knowledge coming down from generation to generation since eternity parallel to Vedic literature which is why its emergence has been said to be from the creator (Brahman) himself prior to the creation. It is taken as eternal because nobody knows when it was not there. In Ayurveda, food is considered to affect the mind as well as the body. By understanding how to prepare foods best suited to our minds and bodies, we can utilize nutrition as a source of healing. Food is the most essential to sustain a good life and the same food if consumed inappropriately becomes the root cause of many diseases. So, proper knowledge about food and its importance should be known by all human beings to have better benefits from it.
A comparative study on damping of finite dry and saturated sand stratum under vertical vibrations
Prathap Kumar, M.T.,Ramesh, H.N.,Raghavebdra Rao, M.V.,Asha, M. Techno-Press 2010 Geomechanics & engineering Vol.2 No.1
Vertical vibration tests were conducted using model footings of different size and mass resting on the surface of finite sand layer with different height to width ratios which was underlain by either rigid concrete base, under both dry and saturated condition. The effect of saturation on the damping ratio of finite sand stratum underlain by a rigid base has been verified and compared with the results obtained for the case of finite dry sand stratum underlain by the rigid base. Comparison of results of the experimental study showed that the damping in both the cases is less than 10%. The damping ratio obtained for finite saturated sand stratum is marginally lower than that obtained on finite dry sand stratum at H/B ratio of 0.5. The difference between the two cases becomes significant when the H/B ratio increases to 3.0, indicating the significant influence of soil moisture on damping ratio of foundation- soil system with increase in the thickness of the finite sand stratum. Comparison of the predicted damping ratio for a homogeneous sand stratum with the experimental damping ratio obtained corresponding to the height to width ratio of 3.0 of the finite sand stratum underlain by the rigid concrete base indicates a significant reduction in damping ratio of the foundation-soil system for both the cases.
Ratio of predicted and observed natural frequency of finite sand stratum
Prathap Kumar, M.T.,Ramesh, H.N.,Raghavendra Rao, M.V.,Raghunandan, M.E. Techno-Press 2009 Geomechanics & engineering Vol.1 No.3
Vertical vibration tests were conducted using model footings of different size and mass resting on the surface of finite sand layer with different height to width ratios and underlain by either rigid concrete base or natural red-earth base. A comparative study of the ratio of predicted and observed natural frequency ratio of the finite sand stratum was made using the calculated values of equivalent stiffness suggested by Gazetas (1983) and Baidya and Muralikrishna (2001). Comparison of results between model footings resting on finite sand stratum underlain by the rigid concrete base and the natural red-earth base showed that, the presence of a finite base of higher rigidity increases the resonant frequency significantly. With increase in H/B ratio beyond 2.0, the influence of both the rigid concrete and natural red-earth base decreases. Increase in the contact area of the footing increases the resonant frequency of the model footings resting on finite sand stratum underlain by both the types of finite bases. Both the predicted and the observed resonant frequency ratio decreases with increase in force rating and height to width ratio for a given series of model footing.

Five day old cotyledon explants of Cucumber (Cucumis sativus L) cv Poinsett 76 were cocultivated with two Agrobacterium strains (EHA105 and LBA 4404) each carrying GUS as the reporter gene and npt-II as the selection marker gene in the T-DNA region of the vector. Transformed shoots were selected at 150 mg/L kanamycin. A two day cocultivation coupled with $20\;{\mu}M$ acetosyringone increased the frequency (8.2 and 15.4 shoots) of GUS expression in the shoots of transformed plant. Among the two Agrobacterium strains, EHA 105 performed better than LBA 4404 in bringing two-fold increase in transformation efficiency (14%) than LBA 4404 (7.4%). PCR analysis was done to confirm the integration of T-DNA into cucumber genome.

Effects of ethylene inhibitors like silver nitrate $(AgNO_3)$, cobalt chloride $(CoCl_2)$ and Salicylic acid (SA) on multiple shoot induction and their impact on ethylene production using embryonal cotyledon cultures of Cucumis sativus L. were examined. The optimum concentration of $AgNO_3\;(40{\mu}M),\;CoCl_2\;(20{\mu}M)\;and\;SA\;(20{\mu}M)$, separately, induced maximum number of shoots on Murashige and Skoog's (MS) medium supplemented optimally with $4.44{\mu}M$ BA and $0.25{\mu}M$ NAA. Among the three ethylene inhibitors tested, $AgNO_3$ produced maximum number of shoots when compared to $CoCl_2$ and SA Ethylene production was monitored in all the treatments with $AgNO_3/CoCl_2/SA$ and it was observed that the treatment with $AgNO_3$ alone showed increase in ethylene production when compared to $CoCl_2$ and SA Even though ethylene concentration was the highest in $AgNO_3$ treated explants, maximum number of shoots was obtained.
