The object of this note is to discuss the relationship between some matrix transformations that naturally occur involving prime numbers in the theory of Summability.
Dynamic Analysis of Semi-submersible Under the Postulated Failure of Restraining System with Buoy
Srinivasan Chandrasekaran,Syed Azeem Uddin,Mubarak Wahab 한국강구조학회 2021 International Journal of Steel Structures Vol.21 No.1
Coupled dynamic analyses of a deep-water Semi-submersible platform, in the South China Sea region, is carried out under postulated damage of the restraining system for both 10 and 100-years return period events. Under the combined action of wind, wave, and current loads, motion responses of Semi-submersible at 1500 and 2000 m water depths are analyzed in timedomain. Dynamic tension variations in the mooring lines are investigated for a fatigue failure using the S–N curve approach. Inclusion of a submerged buoy in the mooring system resulted in a marginal increase of the response due to a reduction in the restoration force of the mooring lines; submerged buoy also resulted in additional damping. The results of numerical studies showed an increase in tension in the mooring lines, which are adjacent to the damaged ones, causing reduced fatigue life. With the inclusion of submerged buoy in the mooring system, there is a considerable decrease in tension variation in mooring lines, increasing fatigue life. Failure of a mooring line causes an increase in tension of the adjacent mooring line, but not valid under all circumstances. It is seen from the studies that despite the postulated failure induced in a mooring, the adjoining line remains unaff ected due to a steady coupling motion of the platform.

The purpose of this paper is to introduce the notion of fuzzyn-inner product space. Ascending family of quasi -n-norms correspond-ing to fuzzy quasi n-norm is introduced and we provide some results onit.
An Experimental Investigation on Geopolymer Concrete Utilising Micronized Biomass Silica and GGBS
Srinivasan Vediyappan,Pazhani Kandukalpatti Chinnaraj,Bharatkumar Bhajantri Hanumantraya,Sundar Kumar Subramanian 대한토목학회 2021 KSCE JOURNAL OF CIVIL ENGINEERING Vol.25 No.6
In the atmosphere greenhouse gases concentration has rapidly increased due to anthropogenic activities which cause global warming. Portland cement manufacturing process requires enormous amount of energy and also consumes huge quantity of natural resources. To overcome this issue, Portland cement free geopolymer concrete is produced with ground granulated blast furnace slag (GGBS) as main binder and micronized biomass silica (MBS) is substituted in place of GGBS at different quantities. Experimental investigation highlighting mechanical properties and durability performance of geopolymer concrete mixes produced with GGBS and MBS are presented here. Rice husk is used in the manufacture of MBS. Compressive, flexural, split tensile strength, elastic modulus and durability parameters like water absorption, sorptivity, rapid chloride permeability test were conducted. Geopolymer concrete mix with 20 percent MBS and remaining GGBS as binder was found to have optimal strength and durability performance. However, the compressive strength was above the target design strength for all the geopolymer concrete mixes. This experimental investigation vindicates the feasibility of utilizing MBS as a binder raw material in geopolymer concrete production.
Tessaracoccus defluvii sp. nov., isolated from an aeration tank of a sewage treatment plant
Srinivasan, S.,Sundararaman, A.,Lee, S. S. Kluwer Academic Publishers [etc.] 2017 Antonie van Leeuwenhoek Vol.110 No.1
<P>A Gram-positive, non-motile, aerobic, coccus-shaped bacterium, designated strain LNB-140(T), was isolated from a sewage treatment plant in the Republic of Korea and was characterised using a polyphasic taxonomic approach. Comparative 16S rRNA gene sequence analysis showed that strain LNB-140(T) belongs to genus Tessaracoccus in the family Propionibacteriaceae of the phylum Actinobacteria. The 16S rRNA gene sequence similarities between strain LNB-140(T) and type strains of the genus, Tessaracoccus flavescens SST-39(T) and Tessaracoccus rhinocerotis YIM101269(T) are 97.8 and 97.4 %, respectively. The chemotaxonomic properties of strain LNB-140(T) are consistent with those of members of the genus Tessaracoccus: a quinone system with MK-9(H4) as the predominant menaquinone; anteiso-C-15:0 and iso C-15:0 as the predominant cellular fatty acids; and ll-2,6-diaminopimelic acid as the diagnostic peptidoglycan diamino acid. The major polar lipids were identified as diphosphatidylglycerol and phosphatidylethanolamine. The G+C content of the genomic DNA was determined to be 67.1 mol%. Differential phenotypic properties along with low DNA-DNA relatedness (< 30 +/- 3.2 %) with closely related type strains show that strain LNB-140(T) is distinct from previously described members of the genus Tessaracoccus and represents a novel species in this genus, for which the name Tessaracoccus defluvii sp. nov. is proposed. The type strain is LNB-140(T) (=KEMB 5401-076(T) = JCM 17540(T)).</P>

<P>Two Gram-negative, non-motile, short rod-shaped bacterial strains, designated as 8A(T) and 28A, were isolated from Mount Deogyusan, Jeonbuk Province, South Korea. The isolates were analyzed by a polyphasic approach, revealing variations in their phenotypic characters but high DNA-DNA hybridisation values reciprocally, confirming that they belong to the same species. Both the isolates also showed a high resistance to UV compared with Deinococcus radiodurans, and a gamma-radiation resistance similar to other members of the genus Deinococcus. Phylogenetic analysis with the 16S rRNA gene sequences of closely related species indicated their similarities were below 97 %. Chemotaxonomic data showed the most abundant fatty acids to be C16:1??7c and C16:0. The strains can be distinguished from closely related species by the production of esterase (C4) and 관-galactosidase, and by their ability to assimilate L-alanine, L-histidine and N-acetyl-D-glucosamine. Based on the phenotypic, phylogenetic, and chemotaxonomic data, the isolates represent a novel species of the genus Deinococcus, for which the name Deinococcus radioresistens sp. nov. is proposed. The type strain is 8A(T) (KEMB 9004-109(T) = JCM 19777(T)), and a second strain is 28A (KEMB 9004-113 = JCM 19778).</P>
