Solution to Some Open Problems on E-super Vertex Magic Total Labeling of Graphs

Let G be a finite graph with p vertices and q edges. A vertex magic total labeling is a bijection f from V(G)∪E(G) to the consecutive integers 1, 2, ..., p+q with the property that for every u∈V(G) , f( u)+ ∑f(uv)=K for some constant k. Such a labeling is E-super if f :E(G)→{1, 2,..., q}. A graph G is called E-super vertex magic if it admits an E-super vertex magic labeling. In this paper, we solve two open problems given by Marimuthu, Suganya, Kalaivani and Balakrishnan (Marimuthu et al., 2015)

Impact of different levels of iron on mitigation of iron chlorosis in varagu CO 3 (Paspalum scrobiculatum. L)

Iron (Fe) deficiency is a major nutritional disorder in crops growing in calcareous soils. Varagu crop are more susceptible to (Fe) deficiency in the early stage of growth and the deficiency is exhibited as chlorosis developing interveinally in the new leaves.  The objective of the present study was to see the impact of different levels iron on mitigation of chlorosis in varagu, Paspalum scrobiculatum under calcareous soil and to investigate the influence of soil and foliar application of iron on growth, physiological and improvement of yield potential of varagu under calcareous soil condition. The varagu variety CO3 taken for this study The treatments comprised T1, NPK (44:22:0 kg ha-1) + 12.5 t  FYM/ha,T2, NPK (44:22:30 kg ha-1) +12.5 t FYM/ha, T3, T1 + Soil application of FeSO4   (25 kg ha-1), T4, T2 + Soil application of FeSO4 (25 kg ha-1), T5, T1 + Soil application of FeSO4 (50 kg ha-1), T6, T2 + Soil application of FeSO4 (50 kg ha-1), T7, T3 + Foliar spray of 0.5% FeSO4, T8, T4 + Foliar spray of 0.5% FeSO4, T9,T5 + Foliar spray of 0.5% FeSO4, T10,  T6 + Foliar spray of 0.5% FeSO4. During experimentation, morphological characteristics, growth attributes, physiological and biochemical components and biomass traits determined the mitigation of iron chlorosis. The iron deficiency in varagu was effectively controlled by T10, soil treatment 50 kg ha-1 FeSO4 and foliar spray of 0.5% FeSO4 applied on the 30th and 50th days after sowing through maintaining highest growth parameter values, maximum catalase and peroxidase activity and maintaining more chlorophyll content

Reducing Cost of Cloud Bandwidth using Prediction-Based System

In Cloud Computing environment we designed and present PACK (Predictive ACKs), end to end traffic redundancy elimination (TRE) system called for cloud computing customers.. PACK’s main advantage is its capability of offloading the cloud-server TRE effort to end clients, thus minimizing the processing costs induced by the TRE algorithm. Unlike previous solutions, PACK does not require the server to continuously maintain clients’ status. Cloud-based TRE needs to apply a judicious use of cloud resources so that the bandwidth cost reduction combined with the additional cost of TRE computation and storage would be optimized. This makes PACK very suitable for pervasive computation environments that combine client mobility and server migration to maintain cloud elasticity. We present a fully functional PACK implementation, transparent to all TCP-based applications and network devices. Finally, we analyze PACK benefits for cloud users, using traffic traces from various sources. PACK is based on a novel TRE technique, which allows the client to use newly received chunks to identify previously received chunk chains, which in turn can be used as reliable predictors to future transmitted chunks

Lie symmetry analysis and group invariant solutions of the nonlinear Helmholtz equation

We consider the nonlinear Helmholtz (NLH) equation describing the beam propagation in a planar waveguide with Kerr-like nonlinearity under non-paraxial approximation. By applying the Lie symmetry analysis, we determine the Lie point symmetries and the corresponding symmetry reductions in the form of ordinary differential equations (ODEs) with the help of the optimal systems of one-dimensional subalgebras. Our investigation reveals an important fact that in spite of the original NLH equation being non-integrable, its symmetry reductions are of Painlev\'e integrable. We study the resulting sets of nonlinear ODEs analytically either by constructing the integrals of motion using the modified Prelle-Singer method or by obtaining explicit travelling wave-like solutions including solitary and symbiotic solitary wave solutions. Also, we carry out a detailed numerical analysis of the reduced equations and obtain multi-peak nonlinear wave trains. As a special case of the NLH equation, we also make a comparison between the symmetries of the present NLH system and that of the standard nonlinear Schr\"odinger equation for which symmetries are long available in the literature.Comment: Accepted for publication in "Applied Mathematics and Computation". 18 pages, 15 figure

Risk factors and perinatal outcome associated with low birth weight in a prospective cohort: is there a shift towards sustainable developmental goal 3

Background: Low birth weight is a socio, economic, cultural and community based health issue which reflects responsibility and commitment of local and national administrative authorities. It continues to be a cause of short and long term adverse perinatal outcome with a bearing on adult non communicable health risks.Methods: This is a prospective observational and analytic study to know the prevalence, risk factors and perinatal outcome of LBW, from July 2017 to December 2018 in department of Obstetrics and Gynecology, MIMS Medical College, Andhra Pradesh, India. Maternal risk factors and outcomes associated with LBW were defined through risk ratios.Results: 721 infants including 116 LBW and 605 NBW born during study period were included in the study. Prevalence of LBW was 16%. Preterm birth accounted for 35%, FGR for 13.8% and SGA for 51.2% of them. Maternal factors like age 35years, social status II to IV, below higher secondary education, house maker, primi gravida, grand multi para, BMI 24.9kg/M2, Hb<11 gm% were having higher RR for LBW. LBW infants showed frequent association with oligo or polyhydramnious and hemorrhagic or turbid amniotic fluid. They had higher risks for non reassuring fetal heart rate changes, for induced delivery or an elective caesarean section. More often they needed NICU care for longer duration and showed a higher risk for malformations and neonatal mortality. Overall perinatal mortality was 5.54 per 1000 live birth.Conclusions: LBW is a risk factor for neonatal morbidity and mortality; which can be minimised by institutional delivery. High prevalence PTB (35%) warrants obstetricians to be more vigilant about indentifying the risk factors and adequate management planning. Constitutionally small baby at birth probably needs redefining normal birth weight for different ethnicity

Not AvailableCottondora Sannalu (MTU 1010) and Jagitial Sannalu (JGL 1798) are widely cultivated rice varieties in Telangana and Andhra Pradesh and very popular among the farmers because of their high yield, slender grain and good cooking quality. Despite their popularity, they are susceptible to many pests and diseases including bacterial blight (BB), caused by Xanthomonas oryzae pv. oryae (Xoo). Two BB resistance genes viz., xa13 and Xa21 were introgressed in these two varieties using marker assisted backcross breeding. Homozygous lines possessing BB resistance genes xa13 or Xa21 and their combination were evaluated for BB resistance with multiple Xoo isolates under controlled condition in glass house and also at different hot spot locations in the states of Telangana and Andhra Pradesh, India. Both the recurrent parents (MTU 1010 and JGL 1798), TN1 (susceptible check) and Improved Samba Mahsuri (resistant check) were also included for resistance evaluation. All the gene-pyramided lines showed high level of resistance against BB both under glass house and field condition. Individually, BB resistance gene xa13 showed higher level of resistance than Xa21. The level of resistance was higher in the lines possessing both the BB resistance genes compared to the lines possessing single BB resistance genes. The results showed that combination of BB resistance genes xa13 and Xa21 can provide broad level of resistance against BB in Telangana and Andhra Pradesh.Not Availabl

Streptococcus pneumoniae Genome Database (SPGDB): A database for strain specific comparative analysis of Streptococcus pneumoniae genes and proteins

Streptococcus pneumoniae causes pneumonia, septicemia and meningitis. S. pneumoniae is responsible for significant mortality both in children and in the elderly. In recent years, the whole genome sequencing of various S. pneumoniae strains have increased manifold and there is an urgent need to provide organism specific annotations to the scientific community. This prompted us to develop the Streptococcus pneumoniae Genome Database (SPGDB) to integrate and analyze the completely sequenced and available S. pneumoniae genome sequences. Further, links to several tools are provided to compare the pool of gene and protein sequences, and proteins structure across different strains of S. pneumoniae. SPGDB aids in the analysis of phenotypic variations as well as to perform extensive genomics and evolutionary studies with reference to S. pneumoniae. (C) 2014 Elsevier Inc. All rights reserved
