On Epsilon-MSCR Codes for Two Erasures

Cooperative regenerating codes are regenerating codes designed to tradeoff storage for repair bandwidth in case of multiple node failures. Minimum storage cooperative regenerating (MSCR) codes are a class of cooperative regenerating codes which achieve the minimum storage point of the tradeoff. Recently, these codes have been constructed for all possible parameters $(n,k,d,h)$, where $h$ erasures are repaired by contacting any $d$ surviving nodes. However, these constructions have very large sub-packetization. $\epsilon$-MSR codes are a class of codes introduced to tradeoff subpacketization level for a slight increase in the repair bandwidth for the case of single node failures. We introduce the framework of $\epsilon$-MSCR codes which allow for a similar tradeoff for the case of multiple node failures. We present a construction of $\epsilon$-MSCR codes, which can recover from two node failures, by concatenating a class of MSCR codes and scalar linear codes. We give a repair procedure to repair the $\epsilon$-MSCR codes in the event of two node failures and calculate the repair bandwidth for the same. We characterize the increase in repair bandwidth incurred by the method in comparison with the optimal repair bandwidth given by the cut-set bound. Finally, we show the subpacketization level of $\epsilon$-MSCR codes scales logarithmically in the number of nodes.Comment: 14 pages, Keywords: Cooperative repair, MSCR Codes, Subpacketizatio

Effect of Different Curing Conditions on Geopolymer Concrete by Partially Replacing sand with Foundry sand

In the present paper, fly ash (no other solid material was used) with highly alkaline solutions is described. These solutions, made with NaOH, Na2Sio3.This paper, report on the study of the processing of geopolymer using fly ash and alkaline activator with geopolymerization process. The factors that influence flexural strength such as different curing condition. The fly ash, fine aggregate with replacement of foundry sand, coarse aggregats and alkaline solution were is used to make geopolymer concrete. The foundry sand is replaced by normal sand in different amount. The main purpose of replacement of foundry sand in to utilize waste by product and save environment also to see the effect on proprety of geopolymer concrete.

REVIEW ON FORMULATION AND EVALUATION OF SOLID LIPID NANOPARTICLES FOR VAGINAL APPLICATION

Vaginal drug administration can improve prophylaxis and treatment of many conditions affecting the female reproductive tract, which includes fungal and bacterial infections, sexually transmitted diseases and cancer also. This is the best route for the administration of proteins, peptides, and also other therapeutic drugs like macro-molecules. For the administration of drugs like contraceptives, steroids, metronidazole, anti-retroviral, vaginal drug delivery is the most preferable route. However, achieving sufficient drug concentration in the vagina can be challenging because of its low permeability. The benefits of the vaginal drug delivery system are it increases the bioavailability, least systemic side effects; easiness of use and self-medication is possible. However vaginal drug delivery system is considered as a less effective route because of the unfortunate absorption of drugs across the vaginal epithelium. The traditional commercial preparations, such as creams, foams, gels, irrigations and tablets, are known to reside in the vaginal cavity for a relatively short period of time owing to the self-cleaning action of the vaginal tract and often require multiple daily doses to ensure the desired therapeutic effect. With the rapidly developing field of nanotechnology, the use of specifically designed carrier systems such as Nanoparticle-based drug delivery has been proven an excellent choice for vaginal application to overcome the challenges associated with the low permeability

Adsorption Efficiency of Cement Impregnated Magnesium Oxide on the Removal of Fluoride

Presence of fluoride in drinking water above the prescribed limit may lead to a severe health complication. We present in this paper the fluoride removal capacity of cement impregnated MgO (MgO-cement) from drinking water. MgO-cement was prepared by adding magnesium oxide (MgO) into the cement slurry solution in the ratio of 1:10. Batch experiments were performed as a function of adsorbent dose, contact time, effect of pH and effect of co-ions. The percentage removal decreases with increasing initial fluoride concentration. Co-ions effect revealed that hydroxide ion was found to interfere more with fluoride removal followed by bicarbonate and least effect with sulphate. Reaction mechanism follows Freundlich isotherms. From the kinetic study we observed that uptake of fluoride ion is fast in the first sixty minutes and equilibrium time found to be independent of the initial fluoride concentration. Adsorption kinetics followed the pseudo second order model showing that the sorption of fluoride is a complex process. Surface as well as intraparticle diffusion contribute in the sorption process. No leaching of magnesium in the treated water was detected

Sol-gel Synthesis and Characterisation of NanocrystallineYttrium Aluminum Garnet Nanopowder

The synthesis of  yttrium aluminum garnet (YAG) (Y3 Al5O12) nanopowder was carried outby sol-gel method. Y(NO3)3.6H2O, Al(NO3)3.9H2O in the presence of citric acid as complexing agent were used as starting materials. YAG nanopowder was characterised by FTIR, TGA, andXRD. To get phase-pure nanocrystalline YAG powder at relatively lower temperature, calcinationat various temperatures was studied and calcination temperature was optimised. Particle size,estimated by XRD using Scherrer's equation, was found to be 28Œ35 nm which was further confirmed by transmission electron microscopy. The particle morphology was studied by SEM.Defence Science Journal, 2008, 58(4), pp.545-549, DOI:http://dx.doi.org/10.14429/dsj.58.167

Secure Database as a Service for Cloud Tenants With no Exposure Of Unencrypted Data

We propose a novel engineering that incorporates cloud database administrations with data mystery and the probability of executing concurrent operations on mixed data. This is the main course of action supporting geographically circled clients to interface particularly to a mixed cloud database, and to execute synchronous and free operations including those changing the database structure. The proposed design has the further favourable position of killing middle of the road intermediaries that breaking point the flexibility, accessibility, and scalability properties that are inborn in cloud-based arrangements. The adequacy of the proposed engineering is assessed through hypothetical investigations and broad test comes about in light of a model execution subject to the TPC-C standard benchmark for various quantities of customers and system latencies

Estimation of serum 25 hydroxy vitamin D level and its correlation with metabolic and endocrine dysregulation in women with PCOS

Background: Polycystic ovarian syndrome is the most common hormonal disturbance in the reproductive age women, with prevalence of 5-10%. Vitamin D deficiency is common in women with or without PCOS. The aim of this study was to assess association of serum vitamin D level with metabolic and endocrine dysregulation in women with PCOS.Methods: This cross-sectional study was done over a period of one year. 100 women of age group 20-40 years were divided in group A 30 (BMI >30 mg/m2) with PCOS, group B 20 (BMI <25 mg/m2) with PCOS, group C 50 controls and were investigated for serum FSH, LH, LH/FSH ratio, S. total testosterone, S. postprandial insulin level, glucose insulin ratio, 25 hydroxy vitamin D level.Results: LH/FSH ratio >2 (33.33% in obese and 50% in non-obese), serum total testosterone level >0.8ng/ml (80% in obese and 75% in non-obese) (p value was significant between study group as well as between study and control group). Serum fasting, postprandial blood glucose, postprandial serum insulin level was elevated in obese than non-obese PCOS. 25 (OH) vitamin D deficiency <20 ng/ml (56.675% in obese and 45% in non-obese). So, vitamin D deficiency was more common in obese PCOS.Conclusions: PCOS is more common in age group of 20-40 years. There is more Insulin resistance in obese PCOS as compared to non-obese PCOS. Vitamin D deficiency is comparatively more common in obese PCOS population than in non-obese PCOS.
