1Long-Term Conservation Agriculture and Intensified Cropping Systems:Effects on Growth,Yield,Water,and Energy-use Efficiency of Maize in Northwestern India显示文摘Conservation agriculture(CA)-based best-bet crop management practices may increase crop and water productivity, while conserving and sustaining natural resources. We evaluated the performance of rainy season maize during 2014 under an ongoing long-term trial(established in 2008) with three tillage practices, i.e., permanent bed(PB), zero tillage(ZT), and conventional tillage(CT) as main plots, and four intensified maize-based cropping systems, i.e., maize-wheat-mungbean, maize-chickpea-Sesbania(MCS), maizemustard-mungbean, and maize-maize-Sesbania) as subplot treatments. In the seventh rainy season of the experiment, maize growth parameters, yield attributes, yield, and water-and energy-use efficiency were highest at fixed plots under ZT. Maize growth parameters were significantly(P < 0.05) superior under ZT and PB compared with CT. Maize yield attributes, including cobs per m^2(7.8), cob length(0.183 m), grain rows per cob(13.8), and grains per row(35.6), were significantly higher under ZT than CT; however, no significant effect of cropping systems was found on maize growth and yield attributes. Zero tillage exhibited the highest maize productivity(4 589 kg ha^(-1)). However, among the cropping systems, MCS exhibited the highest maize productivity(4 582 kg ha^(-1)). In maize, water use was reduced by 80.2–120.9 mm ha-1under ZT and PB compared with CT, which ultimately enhanced the economic water-use efficiency by 42.0% and 36.6%, respectively. The ZT and PB showed a 3.5%–31.8% increase in soil organic carbon(SOC) at different soil depths(0–0.45 m), and a 32.3%–39.9% increase in energy productivity compared with CT. Overall, our results showed that CA-based ZT and PB practices coupled with diversified maize-based cropping systems effectively enhanced maize yield and SOC,as well as water-and energy-use efficiency, in northwestern India.Chiter M.PARIHAR Malu R.YADAV Shankar L.JAT Aditya K.SINGH Bhupender KUMAR Vijay POONIYA Sanatan PRADHAN Rakesh K.VERMA Mangi L.JAT Raj K.JAT Muli D.PARIHAR Hari S.NAYAK Yashpal S.SAHARAWAT 2018Pedosphere2018,28,6:3
2The tumor suppressor RASSF1A is a novel effector of small G protein Rap1A显示文摘Rap1A is a small G protein implicated in a spectrum of biological processes such as cell proliferation,adhesion,differentiation,and embryogenesis.The downstream effectors through which Rap1A mediates its diverse effects are largely unknown.Here we show that Rap1A,but not the related small G proteins Rap2 or Ras,binds the tumor suppressor Ras association domain family 1A(RASSF1A)in a manner that is regulated by phosphorylation of RASSF1A.Interaction with Rap1A is shown to influence the effect of RASSF1A on microtubule behavior.Sunil K.Verma Trivadi S.Ganesan Uday Kishore Peter J.Parker 2011Protein & Cell2011,2,3:3
3美国油气田的新储量增长模型显示文摘储量(或油气田)增长。即最终储量随时间的评价,是一种公认的现象,尤其是在成熟的含油气区。在成熟含油气区精确地预测储量增长的重要性使得我们有必要改进增长函数,并对初始Arrington方法进行评论。在5年期间(1992-1996),初始Arrington方法给出的储量增长比实际石油储量增长高1.03%,而建议的修正方法给出的值在实际增长的0.3%范围内,对储量增长模型的开发来说是可接受的。Mahendra K.Verma 谢力(译) 2005国外石油动态2005,,23:1
4Analysis of Security Vulnerabilities and Countermeasures of Ethernet Passive Optical Network(EPON)显示文摘Ethernet-based Passive Optical Network(EPON) is considered a very promising solution for the first mile problem of the next generation networks.Due to its particular characteristic of shared media structure,EPON suffers many security vulnerabilities. Communication security must be guaranteed when EPON is applied in practice.This paper gives a general introduction to the EPON system,analyzes the potential threats and attacks pertaining to the EPON system,and presents effective countermea-sures against these threats and attacks with emphasis on the authentication protocols and key distribution.Stamatios V.Kartalopoulos Pramode K.Verma 2007China Communications2007,4,3:1

7Does preoperative bacterial culture have bearing on healing of mastoid cavity:A prospective study显示文摘Objective: To study the bacteriological profile in a healing mastoid cavity.Methods: This study was a single centre prospective study. Culture swabs from granulations in the mastoid cavity were sent in 40 consecutive patients with squamosal chronic otitis media undergoing mastoidectomy. Cultures were processed for both aerobic and anaerobic bacteria.Results: Preoperatively: specimens from 26 out of 40(60.5%) had growth on culture, with 22(55%)showing only one organism while 4 showing multiple organisms. The commonest organism isolated was pseudomonas aeruginosa(n = 15).At 1 month after mastoidctomy, 11 patients had sterile culture while 29 had growth, of which 26 had aerobic growth and 3 had anaerobic growth. Pseudomonas was seen in 22 patients and staphylococcus aureus in 2 patients. The mean Merchant score was 2.At 3 months: 29 patients(72.5%) had sterile culture from mastoid cavity while 11 patients(27.5%) had growth on culture. All positive cultures were aerobic, including pseudomonas(n = 9) and proteus(n = 2).The mean Merchant score was 1.03. Of the 40 patients, 16(40%) had a different organism cultured postoperatively compared to preoperative swabs.Conclusion: Pseudomonas and proteus seem to be the most common organisms responsible for persistent otorrhea after mastoidectomy. Persistent sterile otorrhea was seen in 4 patients(10%) in this group at the end of 3 months. Sterile cultures of preoperative swab are more likely to remain sterile in the postoperative period.Roshan K.Verma Niveditha Damodharan Archana Angrup Jaimanti Bakshi Naresh K.Panda 2018Journal of Otology2018,13,2:1
