| 1 | Role of live microbial feed supplements with reference to anaerobic fungi in ruminant productivity: A review显示文摘To keep the concept of a safe food supply to the consumers, animal feed industries world over are showing an increasing interest in the direct-fed microbials(DFM) for improved animal performance in terms of growth or productivity. This becomes all the more essential in a situation, where a number of the residues of antibiotics and/or other growth stimulants reach in milk and meat with a number of associated potential risks for the consumers. Hence, in the absence of growth stimulants, a positive manipulation of the rumen microbial ecosystem to enhance the feedstuff utilization for improved production efficiency by ruminants has become of much interest to the researchers and entrepreneurs. A few genera of live microbes(i.e., bacteria, fungi and yeasts in different types of formulations from paste to powder) are infrequently used as DFM for the domestic ruminants. These DFM products are live microbial feed supplements containing naturally occurring microbes in the rumen. Among different DFM possibilities, anaerobic rumen fungi(ARF) based additives have been found to improve ruminant productivity consistently during feeding trials. Administration of ARF during the few trials conducted, led to the increased weight gain, milk production, and total tract digestibility of feed components in ruminants. Anaerobic fungi in the rumen display very strong cell-wall degrading cellulolytic and xylanolytic activities through rhizoid development, resulting in the physical disruption of feed structure paving the way for bacterial action. Significant improvements in the fiber digestibility were found to coincide with increases in ARF in the rumen indicating their role. Most of the researches based on DFM have indicated a positive response in nutrient digestion and methane reducing potential during in vivo and/or in vitro supplementation of ARF as DFM. Therefore, DFM especially ARF will gain popularity but it is necessary that all the strains are thoroughly studied for their beneficial properties to have a confirmed ‘generally regarded as safe' status for ruminants. | Anil K Puniya Abdelfattah Z M Salem Sanjay Kumar Sumit S Dagar Gareth W Griffith Monica Puniya Sreenivas R Ravella Nikhil Kumar Tejpal Dhewa Ravinder Kumar | 2015 | Journal of Integrative Agriculture2015，14，3： | 17 |

| 3 | CFD modeling to study the effect of particle size on dispersion in 20l explosion chamber: An overview显示文摘Mine disasters occur predominantly due to methane or coal dust explosion or a combination of both.Among the top ten worst coal mine disasters in India, nine are due to coal dust explosion. The current paper describes a general overview of the parameters causing dispersion leading to coal dust explosion,and computational fluid dynamics(CFD) simulation study to observe the effects of particle size on dispersion in Indian coal mines. Turbulent kinetic energy(TKE) and velocity vector path of dust-air mixture and dust-free air were simulated to understand their effects on coal dust dispersion. The TKE contours and velocity vector paths for dust-free air were uniform and symmetrical due to resistance-free path available. The TKE contours and velocity vector paths for dust-air mixture shows the asymmetrical distribution of contours, due to entrainment of air with dust particles. Vortices were observed in velocity vector paths which gradually diminish on increment of time sequence. These vortices are dead centres where velocity and coal dust particles concentration are both zero. | Santosh Kumar Ray Niroj Kumar Mohalik Asfar Mobin Khan Debashish Mishra Nikhil Kumar Varma Jai Krishna Pandey Pradeep Kumar Singh | 2020 | International Journal of Mining Science and Technology2020，30，3： | 3 |
| 4 | 沥青混合料疲劳寿命的新现象学模型研究显示文摘该文对印度公路和道路运输部所规定的3种级配沥青混合料进行了四分点疲劳试验,并评价了其疲劳寿命。试验采用应变控制模式,加载为频率10Hz的正弦加载,温度为20℃。所有混合料的空隙率都控制在(4.0±0.2)%,同时对沥青混合料进行了马歇尔残留稳定度和间接拉伸强度的测试以评价其性能。在此基础上,提出了一个评价沥青混合料疲劳寿命的新现象学模型。试验研究表明:弹性改性沥青疲劳寿命最长,并且具有最低的应变敏感性。塑性改性沥青混合料太脆导致在高应变水平下表现较差,SMA的疲劳寿命比密级配沥青混合料的疲劳寿命高近5倍。新的模型不仅与试验结果高度吻合,而且在统计上也比传统模型更加可靠。 | 冯新军 杨强 赵弘正 Nikhil Saboo Bhaskar Pratim Das Praveen Kumar | 2018 | 中外公路2018，38，3： | 2 |

| 7 | Triple tube drainage for “difficult” gastroduodenal perforations:A prospective study显示文摘AIM To prospectively study the outcome of difficult gastroduodenal perforations(GDPs) treated by triple tube drainage(TTD) in order to standardize the procedure.METHODS Patients presenting to a single surgical unit of a tertiary hospital with difficult GDPs(large, unfavourable local and systemic factors) were treated with TTD(gastrostomy, duodenostomy and feeding jejunostomy). Postoperative parameters were observed like time to return of bowel sounds, time to start enteral feeds, time to start oral feeds, daily output of all drains, time to clamping/removal of all drains, time for skin to heal, complications, hospital stay, and, mortality. Descriptive statistics were used. RESULTS Between December 2013 and April 2015, 20 patients undergoing TTD for GDP were included, with mean age of 44.6 ± 19.8 years and male:female ratio of 17:3. Mean pre-operative APACHE Ⅱ scores were 10.85 ± 3.55; most GDPs were prepyloric(9/20; 45%) or proximal duodenal(8/20; 40%) and mean size was 1.83 ± 0.59 cm(largest 2.5 cm). Median times of resumption of enteral feeding, removal of gastrostomy, removal of duodenostomy,removal of feeding jejunostomy and oral feeding were 4 d(4-5 IQR), 13(12-16.5 IQR), 16(16.25-22.25 IQR), 18(16.5-24 IQR) and 12 d(10.75-18.5 IQR) respectively. Median hospital stay was 22 d(19-26 IQR) while mortality was 4/20(20%). CONCLUSION TTD for difficult GDP is feasible, easy in the emergency, and patients recover in two-three weeks. It obviates the need for technically demanding and riskier procedures. | Nitin Agarwal Nishant Kumar Malviya Nikhil Gupta Iqbal Singh Sanjay Gupta | 2017 | World Journal of Gastrointestinal Surgery2017，9，1： | 1 |
| 8 | Chaos control in a discrete-time predator-prey model with weak Allee effect显示文摘The stability of the predator-prey model subject to the Allee effect is an interesting topic in recent times.In this paper,we investigate the impact of weak Allee effect on the stability of a discrete-time predator-prey model with Holling type-IV functional response.The mathematical features of the proposed model are analyzed with the help of equilibrium analysis,stability analysis,and bifurcation theory.We provide sufficient conditions for the flip bifurcation by considering Allee parameter as the bifurcation parameter.We observe that the model becomes stable from chaotic dynamics as the Allee parameter increases.Further,we observe bi-stability behavior of the model between only prey existence equilibrium and the coexistence equilibrium.Our analytical findings are illustrated through numerical simulations. | Saheb Pal Sourav Kumar Sasmal Nikhil Pal | 2018 | International Journal of Biomathematics2018，11，7： | 1 |
| 9 | A New Design Approach for Nearly Linear Phase Stable IIR Filter using Fractional Derivative显示文摘In this paper,a new design method for digital infinite impulse response(IIR)filters with nearly linear-phase response is presented using fractional derivative constraints(FDCs).In the proposed method,design problem of an IIR frlter is constructed as the minimization of phase error between the desired and designed phase response of an allpass filter(APF)such that the designed lowpass filter(LPF)or highpass frlter(HPF)yields less passband(ep),and stopband errors(es)with optimal stopband attenuation(As).In order to have accurate passband(pb)response,FDCs are imposed on appropriate reference frequency,where the optimality of these FDCs are ensured by using a new greedy based sorting mechanism.The simulated results reflect the efficiency of the proposed method in term of improved passband response along with better transition width.However,small reduction in^is observed within the allowable limit,when compared to noin-fractional design approach,but the designed filter remains immune to wordlength(WL)effect. | Nikhil Agrawal Anil Kumar Varun Bajaj | 2020 | IEEE/CAA Journal of Automatica Sinica2020，7，2： | 1 |

| 15 | A multi-purpose National Forest Inventory in Bangladesh:design,operationalisation and key results显示文摘Background:National forest inventory and forest monitoring systems are more important than ever considering continued global degradation of trees and forests.These systems are especially important in a country like Bangladesh,which is characterised by a large population density,climate change vulnerability and dependence on natural resources.With the aim of supporting the Government’s actions towards sustainable forest management through reliable information,the Bangladesh Forest Inventory(BFI)was designed and implemented through three components:biophysical inventory,socio-economic survey and remote sensing-based land cover mapping.This article documents the approach undertaken by the Forest Department under the Ministry of Environment,Forests and Climate Change to establish the BFI as a multipurpose,efficient,accurate and replicable national forest assessment.The design,operationalization and some key results of the process are presented.Methods:The BFI takes advantage of the latest and most well-accepted technological and methodological approaches.Importantly,it was designed through a collaborative process which drew from the experience and knowledge of multiple national and international entities.Overall,1781 field plots were visited,6400 households were surveyed,and a national land cover map for the year 2015 was produced.Innovative technological enhancements include a semi-automated segmentation approach for developing the wall-to-wall land cover map,an object-based national land characterisation system,consistent estimates between sample-based and mapped land cover areas,use of mobile apps for tree species identification and data collection,and use of differential global positioning system for referencing plot centres.Results:Seven criteria,and multiple associated indicators,were developed for monitoring progress towards sustainable forest management goals,informing management decisions,and national and international reporting needs.A wide range of biophysical and socioeconomic data were collected,and in some cases integrated,for estimating the indicators.Conclusions:The BFI is a new information source tool for helping guide Bangladesh towards a sustainable future.Reliable information on the status of tree and forest resources,as well as land use,empowers evidence-based decision making across multiple stakeholders and at different levels for protecting natural resources.The integrated socioeconomic data collected provides information about the interactions between people and their tree and forest resources,and the valuation of ecosystem services.The BFI is designed to be a permanent assessment of these resources,and future data collection will enable monitoring of trends against the current baseline.However,additional institutional support as well as continuation of collaboration among national partners is crucial for sustaining the BFI process in future. | Matieu Henry Zaheer Iqbal Kristofer Johnson Mariam Akhter Liam Costello Charles Scott Rashed Jalal Md.Akhter Hossain Nikhil Chakma Olaf Kuegler Hossain Mahmood Rajib Mahamud Mohammad Raqibul Hasan Siddique Khaled Misbahuzzaman Mohammad Main Uddin Mohammed Al Amin Farid Uddin Ahmed Gael Sola Md.Baktiar Siddiqui Luca Birigazzi Mahmudur Rahman Ilias Animon Saimunnahar Ritu Laskar Muqsudur Rahman Aminul Islam Heather Hayden Frida Sidik Mondal Falgoonee Kumar Rakibul Hassan Mukul Hossain Nishad Ariful Hoque Belal Asif Reza Anik Abdul Khaleque Md.Shaheduzzaman Syed Shahadat Hossain Tariq Aziz Md.Tauhidor Rahaman Ruhul Mohaiman Patrick Meyer Purnata Chakma A.Z.M.Manzoor Rashid Sourav Das Shrabanti Hira Mohammed Jashimuddin Mohammad Mahfuzur Rahman Karl Wurster Sarder Nasir Uddin Abul Kalam Azad S.M.Zahirul Islam Laurent Saint-André | 2021 | Forest Ecosystems2021，8，1： | 0 |
| 16 | Extracellular Vesicles and Their Significance in COVID-19显示文摘Over the last few years,there is huge scientific attention towards the research related to Extracellular Vesicles(EVs),because of their unique property of inter cellular communications and effective biological significance in diagnosis and therapy[1].Extracellular Vesicles are lipid bilayer membrane bound biological entity,which contains different bioactive compounds(cargoes)such as microRNAs(miRNAs),mRNAs,proteins,and lipids.Based on their origin and size,EVs have been categorized into three different types(a)Exosomes(40 nm-150 nm)are smallest EVs,which are synthesized by endocytic pathways in the cells and secreted in extracellular space through exocytosis process,(b)Microvesicles are secreted from direct budding off plasma membranes and their size varying from 50 nm to 1000 nm and,(c)Apoptotic bodies are formed during apoptotic cell death process and respectively larger in size>1000 nm[1-3].EVs have been identified using different markers,that includes tetraspanins proteins(CD9,CD63,CD81,and CD83),endosomal sorting complexes required for transport(TSG101,Alix),heat shock proteins(Hsp60,Hsp70,Hsp90),and Rab proteins(RAB27a/b)[1]. | Sanjay Kumar Soumi Sadhu Himanshu Narayan Singh Navneet Kumar Dubey Nikhil Kumar Prashant Kumar Tiwari Rajan Malhotra Himani Sharma | 2022 | Advances in Human Physiology Research2022，4，1： | 0 |
| 17 | Inhibiting Protein Aggregation by Small Molecule-Based Colloidal Nanoparticles显示文摘CONSPECTUS:Protein aggregation is associated with different human diseases such as Alzheimer’s,Huntington’s,Parkinson’s,diabetes type II,and cataracts.Currently no effective treatment exists for many of these diseases,particularly for neurological disorders.Ongoing research focuses on understanding the origin of protein aggregation,nucleation−growth mechanism of protein aggregation,origin of cytotoxicity of protein aggregates,cellular response of toxic protein aggregates,progress of diseases at intra/extracellular space,and drug developments for respective diseases.Key issues are the identification of molecular drugs that can inhibit protein aggregation at early stage,lowering of toxicity due to protein aggregates,delivery of drugs to remote organ and intracellular space,clearing matured protein aggregates from cell/extracellular space/brain,and design of effective therapeutic strategy.Chemists and materials scientists have identified a wide variety of antiamyloidogenic small molecules,macromolecules,and nanomaterials.It is shown that antiamyloidogenic molecules prevent protein oligomerization via binding to protein,masking metal ions(via chelating with metal ions)that are responsible for protein aggregation via generating reactive oxygen species(ROS),and lowering protein−protein interaction via macromolecular crowding effect.Similarly,nanoscale materials with curved surface and multiple chemical functional groups act as adsorption/binding sites of proteins,modulate nucleation−growth kinetics of protein aggregation,and delay/inhibit protein aggregation in many cases.However,performance of all these antiamyloidogenic materials needs significant improvement,and proper therapeutic strategies are required for effective drug development.In this Account,we describe that the performance of antiamyloidogenic molecules can be greatly improved via appropriate design into colloidal and nanoparticle form.We first discuss different human diseases that are linked with protein aggregation,location and mechanism of protein aggregation,adverse effect of protein aggregates on cell functions,and progress of different diseases due to these effects.Next,we discuss different classes of antiamyloidogenic materials,their mechanism of inhibiting protein aggregation,and existing approaches for their utilization under in vitro/in vivo conditions.Further,we show that antiamyloidogenic performance of small molecules can be enhanced as high as 100000-times if they are transformed into appropriately designed colloidal nanoparticles.In particular,we explain that such enhanced performance is due to increased bioavailability at intra/extracellular space,modular binding property with protein,and higher brain delivery option in nanoparticle form.Next,we discuss different strategies for the preparation of colloidal nanoparticle where antiamyloidogenic molecules are terminated or loaded with nanoparticle and polymer micelle and their mechanism of action.Finally,we discuss that a wide variety of colloidal nanoparticles can be designed either for inhibiting or disintegrating or clearing of protein aggregates.The Account ends with a“Conclusions and Outlook”section that discuss a vision for development of therapeutic nanodrug for protein aggregation-related diseases. | Koushik Debnath Ankan Kumar Sarkar Nihar R.Jana Nikhil R.Jana | 2022 | Accounts of Materials Research2022，3，1： | 0 |

| 20 | Nanosecond pulse discharge based nitrogen oxides treatment using different electrode configurations显示文摘Nowadays,the intensity of air pollution,due to the industries and automobiles,has been increasing continuously.Nitrogen oxides(NO_(X))are one of the most harmful pollutants,which are getting released from both automobile and stationary diesel engines.They essentially need to be removed from the exhaust using after treatment systems.However,the energy required to remove these pollutants is one of the major considerations in selecting the technology for pollutant removal from diesel engine exhaust.A study has been carried out on the non-thermal plasma-based NO_(X) removal technique using various combinations of power supply units and electrode configurations.Three different electrode configurations are tested,in which two are cylindrical electrodes with diameters 3 and 5 mm,and the other one is a square electrode with a diagonal of 5 mm.A comparison is made between the results with two different pulse power supply units,PS-I:high-voltage direct current test set based and PS-II:DC–DC converter based.The square electrode with PS-Ⅱhas been found to be the optimal combination,which has removed 85%of NO_(X) from the exhaust at an energy density of 55.5 J/L,when the initial NO_(X) concentration in the exhaust is 388 ppm. | Sankarsan Mohapatro Srikanth Allamsetty Apeksha Madhukar Nikhil Kumar Sharma | 2017 | High Voltage2017，2，2： | 0 |
