Pradeep Singh,Vikas Shrivastava,I. B. Singh,D. P. Mondal 대한금속·재료학회 2022 METALS AND MATERIALS International Vol.28 No.6

Three group of porous Ti4Al4Co samples made of (i) unmilled powder and vacuum sintered (S1), (ii) milled powder andvacuum sintered (S2), and (iii) milled powder sintered in open atmosphere (S3) were prepared. Phase change, crystallite sizeand lattice strain variations due to powder milling and sintering were examined by SEM and XRD. To evaluate mechanicalproperty, alloy samples were subjected to the uniaxial compression test. For corrosion analysis, Tafel plot was plotted usingelectrochemical corrosion system in simulated body fluid (SBF) as electrolytic medium. From the obtained results, it wasfound that significant microstructural transformation takes place due to milling and change in sintering atmosphere. SampleS1possessed 139 MPa compressive strength, which was about 48% and 76% higher than samples S2and S3respectively. Corrosion current density for S3was found as 5.5 ± 0.3 μA/cm2 which is 7 and 12 times lower than S2and S1samples.

The goal of this study is to understand how financial inclusion (FI) as influenced by Internet subscribers in India, affects India’s Sustainable Development Goals (SDG). This study makes use of secondary data that was collected from 16 Indian states and one Union Territory between the fiscal years of 2018 and 2020. The goal of this study has been investigated using panel data regression analysis (PDR). And the study’s findings indicate that wages received through MNREGA accounts and post office operating accounts under the supervision of Internet subscribers have a significant negative impact on India’s SDGs, demonstrating how financial inclusion is harming the country’s efforts to achieve sustainable development. This study suggests that it is important to pay attention to rural areas’ access to the digital environment and their degree of digital literacy. These findings imply that improving the MGNREGA program and employees’ pay might help the government alleviate poverty in India. Financial inclusion also depends heavily on financial literacy. The government should improve its digital infrastructure in rural and urban areas so that people there may better understand and utilize it given that it promotes financial inclusion, digitalization, economic advancement, rural development, and poverty reduction.

Lourembam, Deepak Singh,Singh, Asem Robinson,Sharma, T. Dhaneshor,Singh, Th Sudheeranjan,Singh, Thiyam Ramsing,Singh, Lisam Shanjukumar Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.12

Northeastern India is a major nasopharyngeal carcinoma (NPC) high risk-area although the rest of the country has very low incidence. A case-control study of 105 NPC cases and 115 controls was conducted to identify the potential risk factors for NPC development in this region. Information was collected by interviewer about socio-demographic characteristics, cigarette smoking, alcohol consumption, dietary history, occupational history, and a family history of cancer. Epstein-Barr viral load was assayed from the blood DNA by real time PCR. Associations between GSTs genotypes, cytochrome P450 family including CYP1A1, CYP2E1 and CYP2A6 polymorphisms and susceptibility to relationship between the diseases were studied using PCR-RFLP assay. Results indicate that Epstein-Barr virus load was significantly higher in patients compared to controls (p<0.0001). Furthermore, concentration of blood EBV-DNA was significantly higher in advanced stage disease (Stage III and IV) than in early stage disease (Stage I and II) (p<0.05). Presence of CYP2A6 variants that reduced the enzyme activity was significantly less frequent in cases than controls. Smoked meat consumption, exposure to smoke, living in poorly ventilated house and alcohol consumption were associated with NPC development among the population of Northeastern India. Thus, overall our study revealed that EBV viral load and genetic polymorphism of CYP2A6 along with living practices which include smoked meat consumption, exposure to smoke, living in poorly ventilated houses and alcohol consumption are the potential risk factors of NPC in north eastern region of India. Understanding of the risk factors and their role in the etiology of NPC are helpful forpreventive measures and screening.

Purpose: This study compared a) crestal bone loss, b) implant stability quotient (ISQ), c) probing depth, d) denture fracture incidence, and e) posterior residual ridge resorption (RRR) of two implant and single implant-supported overdentures and assessed the quality of life (QOL) was evaluated before and after giving the prosthesis. Materials and Methods: The study was a randomized longitudinal cohort study. Eighty subjects were selected for the study and divided randomly into two groups (n=40): Group 2IOD— two implant-supported overdentures; Group 1IOD— Single implant-supported overdentures. Except for the number of implants, the common surgical, implant, and the prosthetic protocol was followed for the two groups. An oral health impact profile EDENT questionnaire was completed by the patients before giving the implant-supported overdenture and after one year of prosthesis delivery to evaluate the effects of oral health on the quality of life. Probing pocket depth (mm), ISQ (resonance frequency analysis), denture fracture incidence, posterior RRR (mm), and crestal bone loss (mm) were assessed and compared at the baseline and one year after implant placement (early loading protocol) for the two groups. Standard statistical tests, including an unpaired t-test with SPSS software, were used for the analysis. Results: The average crestal bone loss in group 2IOD was insignificantly lower than group 1IOD. The ISQ values were higher for group 2IOD than group 1IOD at one year. The ISQ values for both groups at 12 months were similar (P>0.05). The probing depth at both time intervals yielded insignificant intergroup differences. No denture fracture was reported in either group. At 12 months, posterior ridge resorption in group 2IOD was 0.33±0.08, which was significantly lower than in group 1IOD. Conclusions: A one implant-supported overdenture is a comparable treatment option with two implant-supported overdentures for edentulous patients, having the advantages of lower cost and less surgical trauma. However, there may be more posterior RRR with this treatment modality.

Singh, Housila P.,Tailor, Rajesh,Kim, Jong-Min,Singh, Sarjinder The Korean Statistical Society 2012 응용통계연구 Vol.25 No.4

In this paper, a family of estimators for the finite population variance investigated by Srivastava and Jhajj (1980) is studied under two different situations of random non-response considered by Tracy and Osahan (1994). Asymptotic expressions for the biases and mean squared errors of members of the proposed family are obtained; in addition, an asymptotic optimum estimator(AOE) is also identified. Estimators suggested by Singh and Joarder (1998) are shown to be members of the proposed family. A correction to the Singh and Joarder (1998) results is also presented.

Singh, A.K.,Singh, P.K.,Arya, Madhuri,Singh, N.K.,Singh, U.S. The Korean Society of Plant Pathology 2015 Plant Pathology Journal Vol.31 No.1

Rice Blast is the most devastating disease causing major yield losses in every year worldwide. It had been proved that using resistant rice varieties would be the most effective way to control this disease. Molecular screening and genetic diversities of major rice blast resistance genes were determined in 192 rice germplasm accessions using simple sequence repeat (SSR) markers. The genetic frequencies of the 10 major rice blast resistance genes varied from 19.79% to 54.69%. Seven accessions IC337593, IC346002, IC346004, IC346813, IC356117, IC356422 and IC383441 had maximum eight blast resistance gene, while FR13B, Hourakani, Kala Rata 1-24, Lemont, Brown Gora, IR87756-20-2-2-3, IC282418, IC356419, PKSLGR-1 and PKSLGR-39 had seven blast resistance genes. Twenty accessions possessed six genes, 36 accessions had five genes, 41 accessions had four genes, 38 accessions had three genes, 26 accessions had two genes, 13 accessions had single R gene and only one accession IC438644 does not possess any one blast resistant gene. Out of 192 accessions only 17 accessions harboured 7 to 8 blast resistance genes.

Harjinder Singh Mann,Gurdarshan Singh Brar,Kulwinder Singh Mann,Gurmel Singh Mudahar 한국원자력학회 2016 Nuclear Engineering and Technology Vol.48 No.5

This study aims to determine the effect of fly ash with a high replacing ratio of clay on the radiation shielding properties of bricks. Some interaction parameters (mass attenuation coefficients, half value layer, effective atomic number, effective electron density, and absorption efficiency) of clay fly ash bricks were measured with a NaI(Tl) detector at 661.6 keV, 1173.2 keV, and 1332.5 keV. For the investigation of their shielding behavior, fly ash bricks were molded using an admixture to clay. A narrow beam transmission geometry condition was used for the measurements. The measured values of these parameters were found in good agreement with the theoretical calculations. The elemental compositions of the clay fly ash bricks were analyzed by using an energy dispersive X-ray fluorescence spectrometer. At selected energies the values of the effective atomic numbers and effective electron densities showed a very modest variation with the composition of the fly ash. This seems to be due to the similarity of their elemental compositions. The obtained results were also compared with concrete, in order to study the effect of fly ash content on the radiation shielding properties of clay fly ash bricks. The clay fly ash bricks showed good shielding properties for moderate energy gamma rays. Therefore, these bricks are feasible and eco-friendly compared with traditional clay bricks used for construction.

Deepu Singh,B. Sinha,V. P. Rai,M. N. Singh,D. K. Singh,R. Kumar,A. K. Singh 한국식물병리학회 2016 Plant Pathology Journal Vol.32 No.2

Inheritance of resistance to Fusarium wilt (FW) diseasecaused by Fusarium udum was investigated in pigeonpeausing four different long duration FW resistantgenotypes viz., BDN-2004-1, BDN-2001-9, BWR-133and IPA-234. Based on the F2 segregation pattern, FWresistance has been reported to be governed by onedominant gene in BDN-2004-1 and BDN-2001-9, twoduplicate dominant genes in BWR-133 and two dominantcomplimentary genes in resistance source IPA-234. Further, the efficacy of six simple sequence repeat (SSR)markers namely, ASSR-1, ASSR-23, ASSR-148, ASSR-229, ASSR-363 and ASSR-366 reported to be associatedwith FW resistance were also tested and concluded thatmarkers ASSR-1, ASSR-23, ASSR-148 will be used forscreening of parental genotypes in pigeonpea FW resistancebreeding programs. The information on geneticsof FW resistance generated from this study would beused, to introgress FW resistance into susceptible buthighly adopted cultivars through marker-assisted backcrossbreeding and in conventional breeding programs.
