With the recent developments in the millimeter and sub-millimeter wave instruments and devices, there is a need to developelectromagnetic (EM) wave absorbing materials in these frequency bands for applications like electromagnetic interferencecontrol, electromagnetic compatibility, etc. In this work, carbon nanofi bers (CNF) were uniformly dispersed in a blend ofpoly(methyl methacrylate), polyvinylidene fl uoride and cyanoacrylate for air spray coating a fi lm on the cellulosic substrates. The samples were characterized for evaluation of their structure, morphology, electrical and EM absorption properties in0.15–1.2 THz range by X-ray diff raction, fi eld emission electron microscopy, I–V measurements and terahertz time domainspectroscopy. These coatings can conveniently be applied to the material surfaces by conventional air spray painting method,which makes this technique cost-eff ective as well as easy to deploy in various applications. The electrical conductivityenhancement in the samples has been attributed to the formation of conducting network by uniform distribution of CNFs inthe insulating polymer matrix. As a result, the shielding eff ectiveness (SE) has been observed to improve with the increasein CNF’s loading in the polymer matrix. The SE is also a function of frequency, which is attributed to the increase in theskin depth. A SE of 20 dB has been estimated in these samples for the frequencies 1 THz and higher, which is of signifi cantimportance for the use of this technique in practical applications.

Women’s Unpaid Care Work in Urban Pakistan during COVID-19: Awakening Women’s Agency?

Anam Khan,Aisha Anees Malik 숙명여자대학교 아시아여성연구원 2023 Asian Women Vol.39 No.2

This research records, highlights, and analyzes the experiences of women’s unpaid care work during the pandemic of Covid-19 in Abbottabad, Pakistan. Women’s unpaid care work during Covid-19 occurs in a context where structural discrimination already persists: Women perform a disproportionate share of unpaid care work due to the gendered division of labor. This article addresses the gendered power ideologies underpinning familial relationships in Pakistan that were revealed during the Covid-19 pandemic. Both working women and housewives were obligated to take on additional household responsibilities, constantly switching between roles (mother, housewife, daughter-in-law, employee) to cater for the needs of the family. Through the experiences of Pakistani women, this study shows how Covid-19 has served as an insightful journey for these women who amidst patriarchal ideologies developed an understanding of their individuality, identity, and their significance in this unpaid care work realm. The pandemic prompted them to reflect on their roles as care workers and instilled a sort of agency in them to negotiate, resist, redefine, and maneuver through their subordinated positions to feel empowered and happy. The study also contests the idea of homogeneity inherent in the women’s experiences through the 20 narratives that it discusses with a special focus on the distinctiveness intertwined in the use of agency by these women. Hence, the article subtly explores subjective experiences and contextualizes the reflexive responses of these women during the Covid-19 pandemic.

Introducing the Concept of Intelligent Financial Inclusion

Anam Yasir,Alia Ahmed International Journal of Computer ScienceNetwork S 2023 International journal of computer science and netw Vol.23 No.4

Financial inclusion is the safe and timely access of formal financial services to people at affordable costs. Various barriers of legacy financial system hinder the involvement of all segments of populations in the financial sector. The journey from financial exclusion to financial inclusion has to be achieved with the implementation of technological breakthroughs. Covid-19 has also raised the need for technology in all sectors of the economy. This research paper introduces the concept of intelligent financial inclusion which is the provision of financial services to people with the help of intelligent systems. This intelligent system will take the concepts from the human mind, cognitive sciences, and artificial intelligence tools and techniques. For achieving the optimal level of financial inclusion, economies must shift their financial sector from traditional means to intelligent financial systems. In this way, intelligent financial inclusion will achieve the target of involving all people in the financial sector.

PROTECTION , TERMS OF TECHNOLOGY TRANSFER AND FOREIGN INVESTMENT : A WELFARE ANALYSIS

ANAM, MAHMUDUL,SUPAPOL, ATIPOL BHANICH 한국국제경제학회 1992 International Economic Journal Vol.6 No.4

This paper demonstrates that the welfare of the technology-recipient country can be lower when superior foreign technology is transferred at a more favourable term to a protected sector. It is shown that a decrease in the price of the imported technology increases the output of the protected good. The source of the welfare paradox is therefore this aggravation of production distortion created by the cheaper foreign technology. Furthermore, when the protected good is capital intensive, capital rents are shown to be negatively correlated with the price of foreign technology. Thus, the presence of foreign capital makes the welfare paradox more likely.

Facile fabrication and comparative exploration of high cut resistant woven and knitted composite fabrics using Kevlar and polyethylene

Anam Ali Memon,Mazhar H. Peerzada,Iftikhar Ali Sahito,Sadaf Abbassi,정성훈 한국의류학회 2018 Fashion and Textiles Vol.5 No.1

Composite materials offer a number of distinct advantages in a wide range of low and high technology engineering applications. Considering the fact, in this study, a facile fabrication method of highly cut resistant composite fabrics using Kevlar and polyethylene is reported. 100% Kevlar, 100% Polyethylene and 50% Kevlar/50% Polyethylene composite fabrics are fabricated by weaving and knitting techniques. These fabrics were tested for cut index, abrasion, and puncture resistance for comparative exploration. Owing to higher mechanical strength and greater number of interlacements; the woven fabrics demonstrated twice cut resistance in contrast to knitted fabrics. The surface morphology of deformed samples investigated by Scanning Electron Microscopy (SEM) also proved that the woven fabrics of all types offered much resistance towards cutting than the knitted fabrics. Moreover, it is found that greater thickness of fabrics leads to intensification of the cut resistance. Furthermore, the effect of fiber type on cut resistant property of the fabrics was also measured and it was found that the composite fabric exhibited double cut resistance than 100% Kevlar and 100% Polyethylene fabrics. The 50% Kevlar/50% Polyethylene composite woven fabric resisted up to 35 consecutive strokes of sharp steel cutter whereas the knitted fabric completely torn apart at 20 strokes only. Thus, the as synthesized 50% Kevlar/50% Polyethylene composite woven fabric exhibiting superior cut resistance property offer a judicious choice for the preparation of efficient cut resistant fabric for industrial and domestic applications.

( Anam Giridhar Babu ),( Sang Woo Kim ),( Dil Raj Yadav ),( Umyong Hyum ),( Mahesh Adhikari ),( Youn Su Lee ) 한국균학회 2015 韓國菌學會誌 Vol.43 No.1

The present study is the first report on the isolation of Penicillium menonorum from rhizosphere soil in Korea and its identification based on morphological characteristics and internal transcribed spacer gene sequence. The fungal isolate was named KNU-3 and was found to exhibit plant growth-promoting (PGP) activity through indole acetic acid (IAA) and siderophore production, as well as P solubilization. KNU-3 produced 9.7 mg/L IAA and solubilized 408 mg of Ca3PO4/L, and inoculation with the isolate significantly (p < 0.05) increased the dry biomass of cucumber roots (57%) and shoots (52%). Chlorophyll, starch, protein, and P contents were increased by 16%, 45%, 22%, and 14%, respectively, compared to plants grown in uninoculated soil. The fungus also increased soil dehydrogenase (30%) and acid phosphatase (19%) activities. These results demonstrate that the isolate KNU-3 has potential PGP attributes, and therefore it can be considered as a new fungus to enhance soil fertility and promote plant growth. Moreover, the discovery of PGP ability and traits of this fungus will open new aspects of research and investigations. In this study, plant growth promotion by P. menonorum KNU-3 is reported for the first time in Korea after its original description.

( Anam Kwon ),( Krishnamoorthy Srikanth ),( Eunjin Lee ),( Seonkwan Kim ),( Hoyoung Chung ) 한국동물자원과학회(구 한국축산학회) 2016 한국축산학회지 Vol.58 No.4

Background: Our previous study had identified the SNP (g.81966377T > C) and indel (g.81966364D > I) located in the promoter of APM1 to have a significant effect on marbling in Hanwoo. APM1 encodes an adipocytokine called adiponectin, which plays a significant role in lipogenesis. The aim of this study was to verify and validate the effect of the SNP and indel on marbling and other carcass traits in a large, representative, countrywide population of Hanwoo cattle. The carcass traits measured were marbling (MAR), backfat thickness (BFT), loin eye area (LEA), and carcass weight (CAW). Results: Primers were designed to amplify 346 bp of the genomic segment that contained the targeted SNP (g.81966377) and the indel (g.81966364). After data curation, the genotypes of 8,378 individuals identified using direct sequencing analysis estimated frequencies for C (0.686) and T (0.314) respectively showing genotype frequencies for CC (0.470), CT (0.430) and TT (0.098). The genotypes were significantly associated with MAR, BFT and LEA. The indel had significant effect on marbling (P < .0001) with strong additive genetic effects. The allele frequencies was estimated at (DEL, 0.864) and insertion (INS, 0.136) presenting genotypes of D/D (75.63 %), D/I (21.44 %), and I/I (2.92 %). Significant departure from Hardy-Weinberg equilibrium was not detected for both the SNP and the indel. Conclusion: The SNP genotypes showed significant association with MAR, BFT and LEA with strong additive genetic effects, while the indel was significantly associated with MAR. The results confirmed that the variants can be used as a genetic marker for improving marbling in Hanwoo.
