Baby, S.,Hyeong, K.E.,Lee, Y.M.,Jung, J.H.,Oh, D.Y.,Nam, K.C.,Kim, T.H.,Lee, H.K.,Kim, Jong-Joo Asian Australasian Association of Animal Productio 2014 Animal Bioscience Vol.27 No.11

The accuracy of genomic estimated breeding values (GEBV) was evaluated for sixteen meat quality traits in a Berkshire population (n = 1,191) that was collected from Dasan breeding farm, Namwon, Korea. The animals were genotyped with the Illumina porcine 62 K single nucleotide polymorphism (SNP) bead chips, in which a set of 36,605 SNPs were available after quality control tests. Two methods were applied to evaluate GEBV accuracies, i.e. genome based linear unbiased prediction method (GBLUP) and Bayes B, using ASREML 3.0 and Gensel 4.0 software, respectively. The traits composed different sets of training (both genotypes and phenotypes) and testing (genotypes only) data. Under the GBLUP model, the GEBV accuracies for the training data ranged from $0.42{\pm}0.08$ for collagen to $0.75{\pm}0.02$ for water holding capacity with an average of $0.65{\pm}0.04$ across all the traits. Under the Bayes B model, the GEBV accuracy ranged from $0.10{\pm}0.14$ for National Pork Producers Council (NPCC) marbling score to $0.76{\pm}0.04$ for drip loss, with an average of $0.49{\pm}0.10$. For the testing samples, the GEBV accuracy had an average of $0.46{\pm}0.10$ under the GBLUP model, ranging from $0.20{\pm}0.18$ for protein to $0.65{\pm}0.06$ for drip loss. Under the Bayes B model, the GEBV accuracy ranged from $0.04{\pm}0.09$ for NPCC marbling score to $0.72{\pm}0.05$ for drip loss with an average of $0.38{\pm}0.13$. The GEBV accuracy increased with the size of the training data and heritability. In general, the GEBV accuracies under the Bayes B model were lower than under the GBLUP model, especially when the training sample size was small. Our results suggest that a much greater training sample size is needed to get better GEBV accuracies for the testing samples.

Parametric studies have been conducted into the variability of the factors affecting the ultrasonic testing applied to weldments. The influence of ultrasonic equipment, transducer parameters, test technique, job parameters, defect type and characteristics on reliability for defect detection and sizing was investigated by experimentation. The investigation was able to build up substantial bank of information on the reliability of manual ultrasonic method for testing weldments. The major findings of the study separate into two parts, one dealing with correlation between ultrasonic techniques, equipment and defect parameters and inspection performance effectiveness and other with human factors. Defect detection abilities are dependent on the training, experience and proficiency of the UT operators, the equipment used, the effectiveness of procedures and techniques.

Differential Response of Etiolated Pea Seedlings to Inoculation with Rhizobacteria Capable of Utilizing 1-Aminocyclopropane-1-Carboxylate or L-Methionine

Baby Shaharoona,Muhammad Arshad,Azeem Khalid 한국미생물학회 2007 The journal of microbiology Vol.45 No.1

The majority of soil microorganisms can derive ethylene from L-methionine (L-MET), while some rhizobacteria can hydrolyze 1-aminocyclopropane-1-carboxylate (ACC) due to their ACC-deaminase activity. In this study, three strains having either ACC-deaminase activity (Pseudomonas putida biotype A, A7), or the ability to produce ethylene from L-ME(Acinetobacter calcoaceticus, M9) or both (Pseudomonas fluorescens,AM3) were used for inoculation. The highly ethylene specific bioassay of a classical “triple”response in pea seedlings was used to investigate the effect of the inoculation with the rhizobacteria in the presence of 10 mM ACC or L-MET. The exogenous application of ACC had a concentration-dependent effect on the etiolated pea seedlings in creating the classical “triple” response. The inoculation with P. putida diluted the effect of ACC, which was most likely due to its ACC-deaminase activity. Similarly, the application of Co2+ reduced the ACC-imposed effect on etiolated pea seedlings. In contrast, the inoculation of A. calcoaceticus or P. fluorescens in the presence of L-MET caused a stronger classical“triple” response in etiolated pea seedlings; most likely by producing ethylene from L-MET. This is the first study, to our knowledge, reporting on the comparative effect of rhizobacteria capable of utilizing ACC vs L-MET on etiolated pea seedlings.

The majority of soil microorganisms can derive ethylene from L-methionine (L-MET), while some rhizobacteria can hydrolyze 1-aminocyclopropane-1-carboxylate (ACC) due to their ACC-deaminase activity. In this study, three strains having either ACC-deaminase activity (Pseudomonas putida biotype A, $A_7$), or the ability to produce ethylene from L-MET (Acinetobacter calcoaceticus, $M_9$) or both (Pseudomonas fluorescens, $AM_3$) were used for inoculation. The highly ethylene specific bioassay of a classical 'triple' response in pea seedlings was used to investigate the effect of the inoculation with the rhizobacteria in the presence of 10 mM ACC or L-MET. The exogenous application of ACC had a concentration-dependent effect on the etiolated pea seedlings in creating the classical 'triple' response. The inoculation with P. putida diluted the effect of ACC, which was most likely due to its ACC-deaminase activity. Similarly, the application of $Co^{2+}$ reduced the ACC-imposed effect on etiolated pea seedlings. In contrast, the inoculation of A. calcoaceticus or P. fluorescens in the presence of L-MET caused a stronger classical 'triple' response in etiolated pea seedlings; most likely by producing ethylene from L-MET.

Bio-mimicking hybrid polymer architectures as adhesion promoters for low and high surface energy substrates

Monisha Baby,Vijayalakshmi K. Periya,Bhuvaneshwari Soundiraraju,Nisha Balachandran,Suchithra Cheriyan,Santhosh K. Sankaranarayanan,Satheesh Chandran Maniyeri 한국공업화학회 2021 Journal of Industrial and Engineering Chemistry Vol.100 No.-

Thermoplastic materials like High Density Polyethylene (HDPE) and Polytetrafluoroethylene (PTFE) arepromising candidates for specialty industry/aerospace sectors considering their exceptional propertiesand lower densities. However, the low surface energy leading to poor wetting and reduced adhesioncurtails the scope of their wide-spread usage. In this work, we report adhesion promoter primers basedon epoxy–catechol with and withoutfluorinated polymer and investigated their adhesion promotionefficiency on low/high surface energy substrates. The rational design of catechol-fluorine-epoxy hybridnetwork, mimicking mussel chemistry enabled a non-destructive surface activating approach resultingin profound adhesion promotion. Thefluorine containing primer could effectively enhance adhesionbetween homo and hetero interfaces of Aluminium/HDPE/PTFE owing to the good interface interactionand could outperform common etching methods. A series of molecular level characterizations togetherwith computational and AFM studies provided evidences for the high degree of interaction of the primerbetween the substrates and epoxy-based adhesives. Bond integrity endurance test using a weight of 10and 20 kg resulted in ‘no fail’ categorization for the primed substrates during the entire 40 days testduration. The catechol-functionalized primers reported here can be a good overreaching approach tokeep non-polar substrates afloat in advanced sectors.

COUETTE FLOW OF TWO IMMISCIBLE LIQUIDS BETWEEN TWO PARALLEL POROUS PLATES IN A ROTATING CHANNEL

CH. BABY RANI 한국산업응용수학회 2015 Journal of the Korean Society for Industrial and A Vol.19 No.1

When a straight channel formed by two parallel porous plates, through which two immiscible liquids occupying different heights are flowing a secondary motion is set up. The motion is caused by moving the upper plate with a uniform velocity about an axis perpendicular to the plates. The solutions are exact solutions. Here we discuss the effect of suction parameter and the position of interface on the flow phenomena in case of Couette flow. The velocity distributions for the primary and secondary flows have been discussed and presented graphically. The skin-friction amplitude at the upper and lower plates has been discussed for various physical parameters.

Spatial interdependence of fractal dimension and topological parameters of road network: a geographically weighted regression approach

Daniel Cynthia Baby,Mathew Samson,Saravanan Subbarayan 대한공간정보학회 2021 Spatial Information Research Vol.29 No.5

Road networks are spatial entities that display several geometric, topological variations and fractal nature. The study of the varied properties of road networks is of paramount importance in the field of urban and transport planning. This exploratory research paper aims to study the topological parameters of the road network of Tiruchirappalli city in Tamil Nadu, India based on Graph theory at different scales, i.e., by considering the road network of the study area as 65 wards, 4 zones and the city as a whole entity. The parameters considered in this study include connectivity indices, coverage indices and fractal dimension. Correlation analysis followed by regression analysis is carried out to find the relationship between the variables. The interrelationship between the deduced fractal dimension and other topological parameters of the road network are explored using analytical modelling technique alternatives like Ordinary Least Square (OLS) regression and Geographically Weighted Regression (GWR) by using Geographical Information System (GIS). Results prove that fractal dimension is an indicator of coverage and the fractal dimension of the road network in Tiruchirappalli corporation has a value 1.549 when considered as a whole. It is found that the Geographically Weighted Regression model provides a better fit compared to the ordinary least square regression model. The superiority of the GWR model over the OLS model is because it takes into account the variation of entities over a spatial region. Accessibility analysis for the 65 wards is performed using Shimbel index and it was ascertained that the central wards showed greater accessibility.

Network constrained and classified spatial pattern analysis of healthcare facilities and their relationship with the road structure: a case study of Thiruvananthapuram city

Daniel Cynthia Baby,Mathew Samson,Saravanan Subbarayan 대한공간정보학회 2021 Spatial Information Research Vol.29 No.6

Equity of the utilization of medical facilities is extremely dependant on the spatial distribution of healthcare amenities. In this study, an attempt is made to study the geographic distribution of the various categories of healthcare facilities in the city of Thiruvananthapuram, South India using the centrographic analysis that includes the Mean Center, Standard Deviational Ellipse and Average Nearest Neighbour and it was found that there is an uneven distribution. Network-based point pattern analysis is also performed and cross k-function is used to determine the distribution of medical shops relative to the healthcare services. A weighted node approach is used to calculate the indices of centrality by weighing all nodes based on their degree using Geographical Information System (GIS). Multi centrality assessment model consisting of betweenness, closeness and straightness centrality is used to compute the weighted road centrality on a local and global scale. Kernel Density Estimation technique is applied to modify the centrality values and the vector points to a basic raster framework. Correlation analysis was performed to find the role of the network centrality on the location of healthcare facilities in the study area. Correlation values are greatest among category 2 hospitals; straightness centrality and betweenness centrality favours the location of category 1 hospitals and homeopathy hospitals respectively. The results confirm that network topology influences the location of medical facilities in the study area.
