Objectives: Spinal cord injuries lead to impairment of the respiratory system due to paresis or paralysis of the respiratory muscles leading to respiratory insufficiency, which is dependent on the level and completeness of the injury. The aim of this study was to evaluate the effect of upper limb proprioceptive neuromuscular facilitation (PNF) combined with resistance training on respiratory muscle strength and perceived difficulty of breathing in individuals with tetraplegia. Methods: 26 participants with traumatic tetraplegia C5-C8 participated in the study. They were then allocated in two different groups. PNF Group received upper extremity PNF combined with resistance training for 10 repetitions per set, 3 sets 3 times a week for 4 weeks, and CONT Group received respiratory training with triflow type incentive spirometer. Participants were evaluated for maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP) and modified borg scale (MBS). Results: After four weeks of intervention, there were significant improvement in the scores of MIP, MEP, MBS in both groups separately. Also between group comparison showed significant improvement in scores of MIP (P=0.004), MEP (P =0.004), MBS (P=0.001) in PNF Group as compared to CONT Group. Conclusions: This study concludes that there was significant improvement in respiratory muscle strength and rate of perceived difficulty of breathing using upper limb PNF combined with resistance training in tetraplegics.

Objectives The objective of this in vitro study was to evaluate and compare the cytotoxicity of four different root canal sealers i.e. Apexit Plus (Ivoclar Vivadent), Endomethasone N (Septodont), AH-26 (Dentsply) and Pulpdent Root Canal Sealer (Pulpdent), on a mouse fibroblast cell line (L929). Materials and Methods Thirty two discs for each sealer (5 mm in diameter and 2 mm in height) were fabricated in Teflon mould. The sealer extraction was made in cell culture medium (Dulbecco's Modified Eagle's Medium, DMEM) using the ratio 1.25 cm2/mL between the surface of the sealer samples and the volume of medium in a shaker incubator. Extraction of each sealer was obtained at 24 hr, 7th day, 14th day, and one month of interval. These extracts were incubated with L929 cell line and 3-(4,5-dimethylthiazol-2yl)-2,5-diphenyltetrazolium bromide (MTT) assay was done. Two-way ANOVA for interaction effects between sealer and time and Post-hoc multiple comparison using Tukey's test across all the 16 different groups were used for statistical analysis. Results Apexit Plus root canal sealer was significantly less toxic than other sealers (p < 0.05) and showed higher cellular growth than control. Endomethasone N showed mild cytotoxicity. AH-26 showed severe toxicity which became mild after one month while Pulpdent Root Canal Sealer showed severe to moderate toxicity. Conclusions Apexit Plus was relatively biocompatible sealer as compared to other three sealers which were cytotoxic at their initial stages, however, they became biocompatible with time.

Pandemic induced lockdown as a boon to the Environment: trends in air pollution concentration across India

Gautam Alok Sagar,Sanjeev Kumar,Sneha Gautam,Aryan Anand,Ranjit Kumar,Abhishek Joshi,Kuldeep Bauddh,Karan Singh 한국기상학회 2021 Asia-Pacific Journal of Atmospheric Sciences Vol.57 No.4

The present paper designed to understand the variations in the atmospheric pollutants viz. PM10, PM2.5, SO2, NO2, and CO during the COVID-19 pandemic over eight most polluted Indian cities (Mumbai, Delhi, Bangalore, Hyderabad, Lucknow, Chandigarh, Kolkata, and Ahmedabad). A significant reduction in the PM2.5 (63%), PM10 (56%), NO2 (50%), SO2 (9%), and CO (59%) were observed over Major Dhyan Chand Stadium. At Chhatrapati Shivaji International Airport, a decline of 44% in PM2.5 and 50% in PM10 was seen just a week during the initial phase of the lockdown. Gaseous pollutants (NO2, SO2 & CO) dropped up-to 36, 16, and 41%, respectively. The Air Quality Index (AQI) shows a dramatic change from 7% to 67% during observation at Chandigarh and Ballygunge during the inspection. Whereas, Ahmedabad, Worli, Income Tax Office, Talkatora, Lalbagh, and Ballygaunge have showed a significant change in AQI from 25.76% to 68.55%. However, Zoo Park, CST, Central School, and Victoria show relatively low variation in AQI in the range of 3.0% to 14.50% as compare to 2019 after lockdown. Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) analysis suggested that long range transportation of pollutants were also a part and parcel contributing to changes in AQI which were majorly coming from the regions of Iran, Afghanistan, Saudi Arabia, as well as a regional grant from Indian Gangatic plains and Delhi Non-capital region.

Prabhat Gautam,Anurag Gautam,Neeraj Kumar 한국재료학회 2023 한국재료학회지 Vol.33 No.6

Solar cells based on p-conjugated donor-acceptor (D-A) organic molecular systems are a promising alternative to conventional electrical energy generation. D-A molecular systems, which have a triphenylamine (TPA) moiety linked with a benzothiadiazole (BTD) moiety, open the potential development of new small molecule donors for bulk heterojunction (BHJ) solar cells. Here, a series of donor-acceptor-π-acceptor (D-A-π-A) small molecule donors (SMD) derived from triphenylamine (TPA) donor and benzothiadiazole (BTD) acceptor building blocks, were designed for BHJ organic solar cells. The small molecule donors SMD1-4 were studied using density functional theory (DFT) and time dependent-DFT (TDDFT) methods, to understand the effect of cyano and fluorine group functionalization on their properties. The effect of structure alteration by cyano and fluorine group functionalization on the optoelectronic properties, the calculated highest occupied molecular orbitals (HOMOs) and lowest unoccupied molecular orbitals (LUMOs) and the HOMO-LUMO gaps were theoretically explored. The Voc (open-circuit photovoltage) and fill factor (FF) for SMD1-4 were obtained with a PC71BM acceptor, which showed that these organic small molecules are potential small molecule donors for organic bulk heterojunction solar cells.

Building Bridges: Eurocentric to Intercultural Information Ethics

Gautam, Ayesha,Singh, Deepa World Association for Triple Helix and Future Stra 2021 Journal of Contemporary Eastern Asia Vol.20 No.1

Misguided use, manipulation, misappropriation, disruption and mismanagement of Information deeply affects the infosphere as well as the social and moral fabric of a society. Information ethics is an attempt to bring the creation, organization, dissemination, and use of information within the ambit of ethical standards and moral codes. The diverse and inherently pluralistic nature of societies however puts forth an additional demand on us - to come up with an intercultural information ethics. An intercultural ethics which is other-centric, context sensitive and workable without being homogenizing, patronizing and colonizing. An endeavor in that direction has already been made by proponents of intercultural information ethics like: Charles M. Ess, Fay Sudweeks, Rafael Capurro, Pak-Hang Wong, Soraj Hongladarom et al. In our paper, we propose that the kind of ethical pluralism being sought in the domain of information ethics can be attained by having a reappraisal of the current methodological strategies, by casting a critical relook at the Eurocentric ethical model. This paper analyses the current framework of Intercultural Information Ethics. And in an endeavour to move towards an all-encompassing, other-centric, workable, intercultural, harmonious and compassionate model of 'Pluralistic Information Ethics', it proposes the Indian / Asian philosophical method of 'Samvāda' to the current inventory which includes methods like: 'parrhesia/free speech' and 'interpretive phronēsis.

Effective Signcryption Approach for Secure Convention for Multilayer Consensus using ECC

Gautam Kumar,Hemraj Saini 보안공학연구지원센터 2016 International Journal of Security and Its Applicat Vol.10 No.7

The used algorithm in cryptography represents the facts for compution and/or computation costs in general. The motivation for any problem is primitive generators that makes the protocol a big advantage over the technology augmentation. This manuscript presents a methodological approach on session specific challenge-response protocol for a better, improved and stronger security on reduced costs. The basic primitives are applying on Diffie-Hellman and Elliptic Curve Cryptography. The purpose is proving the security properties for protocol compositional logic that focuses on privacy rights in information assessment in multidisciplinary obligations. In addition, we portrats a signcryption approach for password authenticated key exchange protocol for multilayer consensus, which logically combines individual signature and encryption cost in the form of reduced computational cost and communications cost in single stride of operation. The overall computation time potentially reduces for the proposed methodology on key generation and signature. The results for ECC based multilayer consensus key generation approach are testing on Automated Validation of Internet Security Protocol Architecture (AVISPA) tool and SPAN tool. Further, by preserving the definition of signcryption, we enhanced the same scheme in relations to the other proposed schemes.

The effect of feeding high fat diet to beef cattle on manure composition and gaseous emission from a feedlot pen surface

Gautam, Dhan Prasad,Rahman, Shafiqur,Borhan, Md Saidul,Engel, Chanda Korean Society of Animal Sciences and Technology 2016 한국축산학회지 Vol.58 No.6

Background: Dietary manipulation is a common practice to mitigate gaseous emission from livestock production facilities, and the variation of fat level in the diet has shown great influence on ruminal volatile fatty acids (VFA) and enteric methane generation. The changes in dietary fat levels influence rumen chemistry that could modify manure nutrient composition along with odor and gaseous emissions from manure management facilities. Methods: A field experiment was carried out on beef cattle feedlots to investigate the effect of four levels of dietary fat concentrations (3 to 5.5 %) on the manure composition and gaseous emissions (methane-$CH_4$, nitrous oxide-$N_2O$, carbon dioxide-$CO_2$ and hydrogen sulfide-$H_2S$) from the feedlot pen surface. The experiment was carried out over a 5-month period from June to October during North Dakota's summer-fall climatic condition. Air and manure sampling was conducted five times at a 20-30 day intervals. Results: Overall, this research indicated that fat levels in diet have no or little effect on the nutrient composition of manure and gaseous emission from the pens with cattle fed with different diet. Though significant variation of gaseous emission and manure composition were observed between different sampling periods, no effect of high fat diet was observed on manure composition and gaseous emission. Conclusions: It can be concluded that addition of fat to animal diet may not have any impact on gaseous emission and manure compositions.

Changing Perspectives of Managing Human Resources in Nepal

Gautam, Dhruba Kumar KNU The Institute of Management Economy Research 2012 Asia-Pacific Journal of Business Vol.3 No.2

Sustainable competitive advantage depends on formulation and implementation of appropriate human resource management (HRM) strategies and deployment of their competencies effectively in dynamic and complex environment. Competencies deployment is an approach to make decisions on the intentions and plans of organization concerning employment relationship and its recruitment, training, development, performance appraisal, reward and employee relations policies and practice. The improvement of organizational effectiveness is an overall objective of people management in organizations. In light of these, this study explores the present practices of HRM like: HR departments, HR policies and strategies, HR planning, recruitment selection and placement, training and development, performance appraisal, compensation and benefit, employee relations and communications. Based on the survey in 204 Nepalese organizations as a unit of analysis, the study concludes that HR practices in few organizations have action program for minorities, ethnic group, older employees and people with disabilities. Due to centralized organizational structure, most of HR decisions are taken into central office and line managers being involved highly in planning and implementing HR policies. In a nutshell, though HRM practices are not developed like developed countries, Nepalese organizations are realizing the significance of people management at work and changing their practices in the present dynamic environment.

A Batch Arrival Queue with Bernoulli Vacation Schedule under Multiple Vacation Policy

Gautam Choudhury,Kailash C. Madan 한국경영과학회 2006 Management Science and Financial Engineering Vol.12 No.2

We consider an MX/G /1 queueing system with Bernoulli vacation schedule under multiple vacation policy, where after each vacation completion or service completion the server takes sequence of vacations until a batch of new customer arrive. This generalizes both MX/G /1 queueing system with multiple vacation as well as M /G /1 Bernoulli vacation model. We carryout an extensive analysis for the queue size distributions at various epochs. Further attempts have been made to unify the results of related batch arrival vacation models.
