Purpose The freezing technique and rheological properties play an important role in improving the viscoelastic as well as the textural properties of ice cream. Methods Viscoelastic properties of ice creammix and ice creamwere measured by varying the concentration of gelatin (from0.2 to 0.6%) using the oscillatory test at different frequencies. The rheological analysis was carried out at temperatures 4 °C and − 4 °C which is the temperature of ice cream, before and after carrying out the freezing process, respectively. In ice creammix and ice cream, the values of storage modulus (G′), loss modulus (G″), and tan δ (G″/G′) were calculated from 0.2 to 0.6% gelatin concentration which was prepared by liquid nitrogen (LN2) infusion method. The adaptive neuro-fuzzy logic approach was applied to test the validity of sensory scores obtained in terms of the overall acceptability of ice cream. Results It was found that the viscoelastic property of ice cream was significantly influenced (p ≤ 0.01) by increasing the concentration of gelatin in ice cream and can be successfully added up to the concentration level of 0.4%, beyond which it results in the stiffness of ice cream reducing the quality of ice cream. Also, it was found that the average percentage error in the present ANFIS model was 5.85% with a correlation coefficient of 0.866 which indicates a good amount of correlation between predicted and experimental values. Conclusion The results of this study would be helpful in the further study of quick freezing of ice cream by LN2 infusion method by varying stabilizer concentration which is getting more common nowadays in western countries.

Scalable Energy Efcient Hexagonal Heterogeneous Broad Transmission Distance Protocol in WSN‑IoT Networks

Khyati Shrivastav,Kishor D. Kulat 대한전기학회 2020 Journal of Electrical Engineering & Technology Vol.15 No.1

In this paper hexagonal heterogeneous broad transmission distance protocol (HEXA-HTBTDP) is introduced and scalability analysis is performed in the context of internet-of-things (IoTs). A two-dimensional (2-D) hexagonal feld is taken for the random deployment of sensor nodes which will be benefcial in the recently emerging integrated wireless sensor networkinternet-of-things (WSN-IoTs). This technology opens new horizons for the cellular and mobile communications. With the growing demand for an efcient utilization of resources at present, it is a challenging task to develop clustering protocols which support wirelessly connected heterogeneous sensor nodes. They exist either independently or embedded within devices in the network. With a common objective of achieving energy efciency, reliable communication, connectivity and coverage of network feld, scalability is analyzed by varying the number of nodes and their initial energies. Two-level energy heterogeneity is adopted in the form of normal and advanced nodes. HEXA-HTBTDP is compared with hexagonal feld versions of classical protocols viz. hexagonal stable election protocol (HEXA-SEP) and hexagonal energy efcient heterogeneous clustered scheme (HEXA-EEHC). Benchmarking parameters used for the comparison of results are stability period, network lifetime, instability period, residual energy and energy variance. The hexagonal feld will expand the current scenario of clustering for the achievement of quality of service (QoS) and quality of user experience (QoE) in real time WSN-IoT systems

( Anupama Shrivastav ),( Jin Won Lee ),( Hae Yeong Kim ),( Young Rok Kim ) 한국미생물 · 생명공학회 2013 Journal of microbiology and biotechnology Vol.23 No.7

2,3-Butanediol (2,3-BDO) has immense industrial applications. Recently, microbial fermentation has emerged as an alternative way to produce this industrially important chemical. Although 2,3-BDO is produced by several microorganisms, the Klebsiella genera has an excellent production compared with other 2,3-BDO-producing microorganisms. In order to produce 2,3- BDO on a large scale, the challenges of removing pathogenic factors from Klebsiella pneumoniae need to be addressed. K. pneumoniae produces a number of virulence factors that contribute to its pathogenesis, including lipopolysaccharides, capsules, fimbrial adhesins, etc. Removal of these pathogenic factors from 2,3-BDO-producing Klebsiella strains will result in avirulent strains for the safe, economic, and efficient production of 2,3-BDO. In this review, we summarize the current trends in 2,3-BDO production using K. pneumoniae and insights into the removal of its virulence factors for industrial applications.

The Political System and Processes in India : Problems and Prospects with Special Reference to Southern India

Sanjeev Kumar Shrivastav 경북대학교 아시아연구소 2008 아시아연구 Vol.- No.3

본 논문은 인도의 정치 체계에 대한 고찰을 목적으로 한 소고 형태의 논문입니다. 인도 정치에 대한 새로운 이슈를 제기하기 보다는 인도 정치 제도와 현황에 대한 설명을 통하여 여타의 정치 체제에서는 찾아보기 힘든 인도의 독특 한 정치문화에 대한 이해를 높이고자 합니다. 본 논문에서는 이러한 집필의 의도에 충실히 따르기 위하여 인도의 정치를 여러 가지 단면으로 나누어 각각의 주제에 대한 설명을 나열하는 형식을 취하고 있습니다. 덧붙여 이러한 인도 정 치의 지역별 연구의 시작으로서 남부지역의 주 정부들의 정치적 현황과 제도적 특징 그리고 정치적 경험들에 대하여 간단히 소개함으로서 남부 인도에서의 정치적 성과에 대해 소개하고자 합니다. 인도 문명은 유럽, 이슬람교 사회뿐만 아니라 유교와 불교의 영향을 받은 동아시아의 문명과도 구분되는 독특한 면을 가지고 있다. 1947년 8월 15일 독립당시의 4억 인구는 현재에 이르러 10억을 초과한 상태이다. 알려진 대로 인도는 선거권을 가진 인구의 수와 정치에 참여하는 정당의 숫적 측면에서 보면 세계 최대의 민주주의 국가이다. 또한 인도에는 다양한 종류의 이해집단들이 존재하고 있다. 이러한 이해집단들은 지역, 언어, 계급, 종교 등 여러 가지 다각적인 사회 정체성을 가진 집단들이다. 이들 이해집단들은 자신들의 처한 상황에 따라 다양한 요구들을 표출하고 있다. 이러한 요구들은 인도 내에서 자신들의 문화에 대한 자치권에 대한 요구도 있으며, 더 나아가 자치 독립 국가를 원하는 집단들도 존재하고 있다. 이러한 여러 가지 다양한 문제들에도 불구하고 인도는 하나의 독립국가로서 독립이후 존재해오고 있다. 인도는 연방 의회제의 민주 국가이며, 여러 정당의 대표가 있다. 실질적인 인도의 정치권력은 수상이 수행하지만, 형식적인 권력은 대통령에게 있다. 이것은 영국의 군주제도에서 왕이 차지하는 위치와 같은 표면상의 국가수반의 지위에 해당한다. 행정은 정부가 담당하고 있으며, 연방의 입법에 대한 권한은 정부와 상원과 하원으로 구성된 인도 의회에 있다. 사법은 입법과 행정으로부터 독립되어 기능하고 있다. 인도 연방제는 정당의 분열과 의회 권력의 약화 그리고 일반 대중들의 정치적 압력으로 인하여 다른 연방제 국가들과 비교하여 중앙 집중화 정도가 약한편이다. 시장 개혁과 몇 몇 주들에서 받아들인 세계 은행의 구조 조정 계획 그리고 투자에 대한 인도 국내 수요의 증가로 인하여 연방제는 여러 가지 경제적 문제에 직면해 있다. 경제문제에 대한 의사결정의 권한을 개별 주 정부에 부여함으로 인하여 투표를 의식한 대중적 정당의 정책 등으로 재정 문제는 악화되 었으며, 또한 불균형 발전이 가속화 되었다. 중앙 정부와 지방정부간의 정치와 안보에 관한 견해 차이로 인하여 중요한 정치적 문제들이 나타나고 있다. 또한 새로운 주를 만들기 위한 정치적 집단들의 움직임도 있으며, 촌락단위 정치 의 결 조직에 대한 헌법 조항을 설립하려는 정치적 움직임도 있다. 이처럼 연방제로 인하여 인도는 중앙 정부의 권한이 강화되기 보다는 지방정부의 권력이 강화되면서 지역, 언어, 카스트, 계급 등의 다양한 문제들이 중요한 정치적 과제 로 등장하게 되었다. 1999년의 의회 선거 이후로 중앙 정부는 20개의 중소 지역 정당들이 참여한 연합 정부를 구축하였으며, 당분간 이러한 연합 정부 형태는 지속될 것으로 보인다. 이러한 외적 내적 문제들에도 불구하고 인도는 매우 성공적인 민주주의적 질서와 정부를 유지해 오고 있다. 현재까지 인도는 독립이후 파키스탄과 중국 에 대항하여 네 번의 전쟁을 겪어왔다. 그리고 자무와 카시미르 지역, 북동 지역 그리고 펀잡지역에서 계속되는 반정부 시위를 겪고 있다. 현재 인도는 모택동주의자들과 낙살라이트들의 반정부 시위를 경험하고 있다. 카스트와 부족 문제들은 여전히 해결의 기미를 보이지 않고 있으며, 인도의 법과 질서에 위험을 안겨줄 수 있는 중대한 과제로 등장하였다. 무엇보다 가장 큰 문제는 전 세계에 있어 현재 가장 큰 정치적 위험이 되고 있으며, 수년간 인도를 계속해서 고통에 빠뜨리는 테러리즘과의 전쟁을 현재 수행하고 있다는 것이다. 인도는 이러한 모든 정치적 문제들에 대해서 용기와 신념을 갖고 싸워왔다. 이러한 심각한 문제들에 대항하여 힘든 싸움을 해오면서도 인도는 국민들의 복지와 빈곤퇴치를 위해 성공적인 성과를 거두어왔다. 이러한 측면에서 본다면 남부 인도의 여러 주 정부들은 다른 지역의 주 정부와 비교하여 상대적으로 성공적이었으며, 국민들의 복지와 빈곤퇴치에 성공적이었음을 알 수 있다. Indian civilization is distinct from the East Asian, mainly Confucian and Buddhist inspired civilizations, as well as from European or Islamic societies. When India attained independence on 15th August, 1947, its population was around 400 million people. Now there are more than a billion people in India. India is the largest democracy in the world. It has the biggest number of people with franchise rights and the largest number of political parties, which take part in election campaign. India also has many internal problems. Different communities with different identities-regional, language, caste, religion-demanded different rights for their communities. Some communities demanded more autonomy for their cultures within the Indian states. Others demanded autonomous states within the Indian Union, while the others demanded to be independent from India. With all its problems India survives as a single state with democratic character. India is a federal parliamentary democratic state, having multiparty representation. The Prime Minister of India is the head of government, while the President of India is the formal head of state and holds substantial reserve powers, placing him or her in approximately the same position as the British monarch. Executive power is exercised by the government. Federal legislative power is vested in both the government and the two chambers of the Parliament of India. The judiciary is independent of the executive and the legislature. Indian federalism has become less centralized as a result of popular pressures, the breakdown of Congress dominance, and the fragmentation of political parties. Economic challenges to cooperative federalism emerge from market reforms, the search for investments, and the World Bank structural adjustment plans adopted in selected states. Devolution of economic decision-making to the states aggravates fiscal crises by facilitating populist political strategies and accentuating uneven development. Political challenges arise from issues such as central vs. state control of police and security forces; movements for the creation of new states; and the implementation of constitutional provisions for village-level governance. Change in India’s federalism has come about less through the adaptation of formal institutions than through the proliferation of state-based political parties, aggregating varied interests based on region, language, caste, class, or views on secularism. After the elections of 1999, more than 20 parties managed to provide a stable national coalition government, transforming the political processes. At present India has a coalition government and the same coalition is likely to remain in upcoming years in Indian politics.

Estimating the prevalence of oral manifestations in COVID-19 patients: a systematic review

Ankita Gupta,Kriti Shrivastav,Amit Agrawal,Abhishek Purohit,Roshan Chanchlani 질병관리본부 2023 Osong Public Health and Research Persptectives Vol.14 No.5

Objectives: Patients with coronavirus disease 2019 (COVID-19) present with a variety of oral manifestations. Therefore, we conducted a systematic review to estimate the prevalence of oral lesions among COVID-19 patients. Methods: An extensive literature search of several electronic bibliographic databases (PubMed, Scopus, Science Direct, Litcovid) was conducted to retrieve all articles published in the English language from January 1, 2020 to March 31, 2023 that reported the prevalence of oral manifestations among COVID-19 patients. A meta-analysis of pooled prevalence was performed using Jamovi ver. 2.3 (2022). The I2 and Q statistics were used to assess heterogeneity between studies, and p-values <0.01 were considered statistically significant. Results: In total, 79 studies with data from 13,252 patients were included. The articles were predominantly published in 2020 (n=33), and Italy was the most common country (n=14). Most of the affected patients more than 50 years old and women (56.6%). The most common sites of involvement were the tongue (n=65), followed by the oral mucosa (n=37) and lips (n=19). High heterogeneity was found between studies. The most common oral manifestation was taste alteration, followed by xerostomia and ulceration, showing pooled prevalence rates of 48%, 35%, and 21%, respectively. Conclusion: COVID-19 patients show various oral manifestations that may help clinicians identify the disease promptly. Recognition of the signs and symptoms of COVID-19 is critical for an early diagnosis and better prognosis.

Sindhadevi, M.,Kanagasabai, Malathi,Arun, Henridass,Shrivastav, A. K. The Korean Institute of Electrical Engineers 2016 Journal of Electrical Engineering & Technology Vol.11 No.1

This paper brings out a novel method for reducing Near end and Far end Crosstalk using Electromagnetic Band Gap structures (EBG) in High Speed RF transmission lines. This work becomes useful in high speed closely spaced Printed Circuit Board (PCB) traces connected to multi core processors. By using this method, reduction of −40dB in Near-End Crosstalk (NEXT) and −60 dB in Far End Crosstalk (FEXT) is achieved. The results are validated through experimental measurements. Time domain analysis is performed to validate the signal integrity property of coupled transmission lines.

Recent trends in the mass cultivation of algae in raceway ponds

Kumar, Kanhaiya,Mishra, Sanjiv K.,Shrivastav, Anupama,Park, Min S.,Yang, Ji-Won Elsevier 2015 RENEWABLE & SUSTAINABLE ENERGY REVIEWS Vol.51 No.-

<P><B>Abstract</B></P> <P>Algal technology has potential to combat the global energy crisis, malnutrition, and production of several value added products useful for the mankind. The cost effective cultivation system is the basis to realize this goal. Microalgal production in raceway ponds seems to be most promising, especially in the large scale. Several environmental (location of the cultivation system, rainfall, solar radiation, etc.), engineering (pond depth, CO<SUB>2</SUB> delivery system, methods of mixing, power consumption, etc.), and biological (light, pH, oxygen accumulation, salinity, Algal predators etc.) parameters affect the biomass productivity in the open pond system. Vertical mixing is an important criteria influencing the algal growth compared to axial mixing as it determines the frequency by which cell will travel from bottom (dark zone) to surface (light zone) of the open pond. Therefore, different research works on the various designs of raceway ponds were mostly focused towards enhancing the vertical mixing (e.g. Design of bend and surface geometry, engineering flow field, etc.) and CO<SUB>2</SUB> residence time (e.g. Closed, sump, airlift driven raceway ponds etc.). The present study summarizes the current state of knowledge for the biomass production in raceway ponds.</P>
