Block Chain for Financial Application using IOT

The Internet of Things (IoT) has become a popular computing technology paradigm. It is increasingly being utilized to facilitate human life processes through a variety of applications, including smart healthcare, smart grids, smart finance, and smart cities. Scalability, interoperability, security, and privacy, as well as trustworthiness, are all issues that IoT applications face. Blockchain solutions have recently been created to help overcome these difficulties. Therefore, this paper describes the concept of providing security for payment processing involved in IOT devices and their service usage by applying Blockchain technology. Blockchain is a secured distributed cryptographic hashing technique which maintains transaction in a transparent and unalterable format. It maintains block of chained transaction and keeps on validating old and new transaction and if old hash matched then only transaction will be consider as successfully verified. All users’ transaction will be privacy protected and this same technique applied in this project to secure payment process happen between users and company services. All data in this project saved inside Blockchain and authentication and privacy will be performed by using DSA (digital signature algorithm) and SHA hashing technique

Components of Resistance to an Indian Source of Cercospora Arachidicola in Selected Peanut Lines

Cercospora arachidicola Hori is one of the most important foliar pathogens worldwide that limits peanut production in farmers' fields. Earlier screening trials allowed us to identify lines with field resistance to early leafspot. In order to determine the components of resistance of these lines and other lines reported to be resistant elsewhere, 19 peanut genotypes (Arachis hypogaea L.) were evaluated by the detached leaf technique using an isolate of Cercospora arachidicola from the ICRISAT Center in India. Significant differences were observed among genotypes for all components of resistance included in the study. With a few exceptions, early leafspot- resistant genotypes (ICG nos. 8298, 6902, 6284, 1703, 10900, 7878, 9989 and 10920) exhibited longer incubation periods, reduced sporulation, smaller lesion diameters and lower infection frequencies than susceptible lines. Genotypes ICG 8298 and ICG 6902 were the most resistant, while ICG nos. 221, 7827 and 6340 were the most susceptible to early leafspot. A few lines had resistant reactions to some components but susceptibility to others

Identification of a virus naturally infecting sorghum in India as Sugarcane streak mosaic virus

The virus associated with mosaic disease of sorghum growing around the sugarcane fields in Andhra Pradesh state, India was found to be serologically related to the Sugarcane streak mosaic virus (SStMV) and Sorghum mosaic Parbhani virus (SMPV). The reverse transcription-polymerase chain reaction (RT-PCR) of the total RNA from the enzyme-linked immunosorbent assay positive sorghum samples with the potyvirus specific degenerate primers yielded an amplicon of ∼500 bp. This amplicon sequence had a 95% identity to the SStMV-Andhra Pradesh (SStMV-AP) and SStMV-Coimbatore isolates reported to naturally infect sugarcane in India. Further confirmation was made by RT-PCR of these samples with the SStMV-AP sequence specific primers that yielded ∼1,000 bp amplicon comprising the entire coat protein and 3′ UTR of the viral genome. This amplicon sequence also had a identity of 95% at nucleotide level with the SStMV-AP sugarcane isolate, but at the CP amino acid level it had 97.8% identity. This partial sequence data confirmed the association of SStMV with the mosaic disease of sorghum in Andhra Pradesh state, India. To our knowledge, this is the first report on association of SStMV with mosaic disease of sorghum and designated as SStMV-sorghum isolat

Studies on atmospheric gravity wave activity in the troposphere and lower stratosphere over a tropical station at Gadanki

MST radars are powerful tools to study the mesosphere, stratosphere and troposphere and have made considerable contributions to the studies of the dynamics of the upper, middle and lower atmosphere. Atmospheric gravity waves play a significant role in controlling middle and upper atmospheric dynamics. To date, frontal systems, convection, wind shear and topography have been thought to be the sources of gravity waves in the troposphere. All these studies pointed out that it is very essential to understand the generation, propagation and climatology of gravity waves. In this regard, several campaigns using Indian MST Radar observations have been carried out to explore the gravity wave activity over Gadanki in the troposphere and the lower stratosphere. The signatures of the gravity waves in the wind fields have been studied in four seasons viz., summer, monsoon, post-monsoon and winter. The large wind fluctuations were more prominent above 10 km during the summer and monsoon seasons. The wave periods are ranging from 10 min-175 min. The power spectral densities of gravity waves are found to be maximum in the stratospheric region. The vertical wavelength and the propagation direction of gravity waves were determined using hodograph analysis. The results show both down ward and upward propagating waves with a maximum vertical wave length of 3.3 km. The gravity wave associated momentum fluxes show that long period gravity waves carry more momentum flux than the short period waves and this is presented

Beneficiation of iron ore fines by conventional flotation, flotation column and dual extraction column – A pilot scale study

Goa state in India is endowed with large deposits of low-grade iron ores, geologically formed from lower Dharwar super group of Archaean rocks. Petrological studies have revealed that silica and alumina are the main gangue minerals where alumina exists as fine clay and adherent material interspersed in the ore body and in some cases both silica and alumina interlocked with iron ore particles. Efficiency of conventional flotation, column flotation and dual extraction column for separation of gangue was studied on a pilot scale at Greater Ferromet Beneficiation Plant of M/s. Sociedade De Fomento Industrial Ltd., Goa. Reverse flotation process was adopted wherein gangue minerals silica and alumina were floated using cationic amine collector. Sodium hydroxide and starch were used to regulate the slurry pH and to depress iron ore, respectively. Various iron ore samples drawn from different mines and their mixtures were subjected to the test work. Results of pilot scale tests clearly indicate the superiority of flotation column vis-a-vis conventional cells and dual extraction column. Iron ore concentrate assaying 67 % Fe and 2 % Si02 and AI203 with a recovery of 85 - 90 % could be obtained by single stage flotation column operation

Save cells before tooth replantation: A review

Avulsion is one of the most complex traumatic injury affecting both teeth and children. Avulsed teeth can be replanted. Treatment for avulsed teeth should include, pulp and periodontal ligament (PDL) cell management to increase the survival rate of these teeth. If immediate replantation is not possible, the clonicity and progenicity of the viable PDL cells can be maintained with the aid of suitable storage medium at the place of trauma. The incorrect use of a storage medium leads to PDL cell necrosis eventually resulting in ankylosis and replacement resorption of the tooth root. Due to the importance of the storage media in long-term prognosis of the avulsed teeth, an informed choice of a media is essential for a favorable outcome. This review discusses available storage media and their unique features along with pros and cons of each medium

Concomitant mandibular hypo-hyperdontia: Report of two rarest cases with the literature review

Concomitant occurrence of both hypodontia (congenital tooth agenesis) and hyperdontia (supernumerary tooth) in the same dental arch is an extremely rare dental anomaly. Literature search shows very few cases of this anomalous condition with all cases depicting the unilateral presence of supernumerary tooth. Therefore, the intention of the current article is to report two cases of concomitant occurrence of mandibular both hypo-hyperdontia. In that one case exhibited bilateral occurrence of mesiodens teeth in the midline of mandible with associated agenesis of permanent both central incisors and taurodontism in permanent molars, which is not published so far. The article also provides comprehensive literature review on this rarest clinical entity

Unsteady flow of a nanofluid over a sphere with nonlinear Boussinesq approximation

A theoretical study is presented of transient mixed convection boundary layer flow of a nanofluid in the forward stagnation region of a heated sphere which is rotating with time dependent angular velocity. The effect of the non-linear Boussinesq approximation is taken into account. The nanofluid is treated as a two-component mixture i.e. nano-particles distributed homogenously in a base fluid (water or gas). The effects of the Brownian motion and thermophoresis are included for the nanofluid and constant wall temperature is imposed at the sphere surface. The first and second laws of thermodynamics are employed in order to study thermophysics as well as heat and mass transfer phenomena. By introducing appropriate similarity variables the governing equations are transformed into a system of dimensionless, nonlinear, coupled, ordinary differential equations which are solved numerically by applying the second-order accurate implicit finite difference Keller box method. The reliability and efficiency of the obtained numerical results are validated via comparison with the previously published results for special cases. The effects of various parameters on primary and secondary velocities, temperature, nanofluid volume fraction (concentration), primary and secondary shear stress functions, Nusselt number function (wall heat transfer rate) and Sherwood number function (wall nanoparticle mass transfer rate) are visualized. Furthermore the influence of non-linear temperature parameter, Brinkman parameter (ratio of Brinkman number to dimensionless temperature ratio), local Reynolds number and unsteadiness parameter on entropy generation number is computed. A strong elevation in entropy generation number is computed with both increasing Brinkman parameter and unsteadiness parameter. Primary and secondary surface shear stresses, Nusselt number and Sherwood number also increase with unsteadiness and rotation parameters. Primary shear stress is boosted with increasing mixed convection parameter and Brownian motion effect whereas secondary shear stress is depressed. Temperatures are suppressed with increasing nonlinear temperature parameter whereas nano-particle concentrations are elevated. Increasing thermophoresis parameter enhances both temperatures and nano-particle concentration values. The simulations find applications in rotating chemical engineering mixing systems and nano-coating transport phenomena
