| 1 | Changes in Germination and Seedling Traits of Sesame under Simulated Drought显示文摘Drought is considered one of the leading abiotic constraints to agricultural crop production globally.Present study was conducted to assess the effects of different drought treatments(viz.Control,10%PEG,and 20%PEG)on seed germination,germination indices,seedling traits,and drought tolerance indices of sesame.Our results showed that maximum reduction in the studied parameters was observed at higher PEG concentration(i.e.,20%PEG).As compared to control,the drought treatments viz.10%and 20%PEG decreased the values for germination indices,such as germination percentage,coefficient of variation of germination time,germination index,and seedling vigor index.Similarly,for seedling traits,the values were decreased for root length,shoot length,root shoot ratio,root fresh weight,shoot fresh weight,root dry weight and shoot dry weight under 10%and 20%PEG treatments significantly in comparison with control.Furthermore,relative to control,the values for drought tolerance indices,such as germination drought tolerance index,root length drought tolerance index,shoot length drought tolerance index,total seedling length drought tolerance index,root fresh weight drought tolerance index,shoot fresh weight drought tolerance index,total fresh weight drought tolerance index,root dry weight drought tolerance index,shoot dry weight drought tolerance index and total dry weight drought tolerance index were also reduced under 10%and 20%PEG treatments,respectively.Our results confirms that drought impact on seed germination and seedling traits could be quantified by using different indices which can further help to design drought adaptation and mitigation strategies.Based on these results it can be concluded that germination indices,seedling traits,and drought tolerance indices have great potential to simulate drought stress impacts on different crop traits thus they should be used in all kinds of stress related studies. | Mukhtar Ahmed Ahmed M.S.Kheir Muhammad Zeeshan Mehmood Shakeel Ahmad Mirza Hasanuzzaman | 2022 | Phyton-International Journal of Experimental Botany2022,91,4: | 1 |
| 2 | Outcomes after stenting for malignant large bowel obstruction without radiologist support显示文摘AIM:To assess outcomes after colonic stent insertion for obstructing colorectal malignancies performed by an endoscopist without radiologist support.METHODS:This is a retrospective study of all stents inserted by a single surgeon in a District General Hospital over an eight year period.All stents were inserted for patients with acute large bowel obstruction secondary to a malignant colorectal pathology either for palliation or as a bridge to surgery.Procedures were performed by a single surgeon endoscopically with fluoroscopic control in the X-ray department but withoutthe support of an interventional radiologist.Data was collected prospectively on a pre-designed database.RESULTS:The indication for all stent procedures was an obstructing colorectal malignancy.Out of 53patients,the overall success rate was 90.6%.Eight patients had a stent intended as a bridge to surgery and 45 as a palliative procedure.Technical success was achieved in 50 out of 53 procedures(94.3%)and clinical success in 48 of those remaining 50(96.0%).Those with unsuccessful technical or clinical procedures went on to have defunctioning stomas to treat their obstruction.There were six complications from the technically successful stents(12.0%).These included one migration,one persisting obstructive symptoms and four cases of tumour overgrowth of the stents at a later date.Haemorrhagic complications,perforation or mortality were not observed in our series.Our results are comparable to several other studies assessing stent outcomes for obstructing bowel cancer.CONCLUSION:Our data suggests that colorectal stents can be inserted without radiologist support by an adequately trained individual with good outcomes. | Rao Khalid Mehmood Jody Parker Patricia Kirkbride Shakil Ahmed Fayyaz Akbar Eays Qasem Muhammad Zeeshan Ernest Jehangir | 2014 | World Journal of Gastroenterology2014,20,20: | 1 |

| 4 | 不同土壤氮水平下C_(3)和C_(4)植物之间的菌根网络及氮传递显示文摘丛枝菌根真菌(AMF)的菌丝在土壤中通常可以链接相同或不同物种的植物根系,所形成的菌根网络可以将养分从一种植物传递到另一种植物。然而,土壤中的氮(N)含量对不同植物物种之间通过菌根网络进行养分转移的影响尚未实验验证。为了定量研究不同土壤氮水平下羊草(LC)和糙隐子草(CS)之间通过菌根网络的养分转移,本研究建立了两个分室盆栽系统,即CS–LC系统(CS和LC分别为供体和受体)和LC–CS系统(LC和CS分别为供体和受体),设置了3种土壤氮添加水平,即不添加氮对照(N0)、添加7 mg/kg(N1)和添加14 mg/kg(N2)。通过在供体植物一侧土壤添加稳定同位素^(15)N,示踪并量化不同物种植物幼苗之间通过菌根网络传递的氮。在CS–LC系统中,AMF侵染率、菌丝密度和植物生物量在N1水平最高;而在LC–CS系统,AMF侵染率、菌丝密度和植物生物量在N2水平达到最大。此外,在CS–LC系统中,^(15)N转移率介于16%到61%之间,在N1水平最大。对于LC–CS系统,^(15)N传输速率相对较低,最大值出现在N0水平。这些发现表明,土壤中的氮含量能够调控供体植物和受体植物之间经由菌根网络传递的氮养分。 | Muhammad Atif Muneer Xiaohui Chen Muhammad Zeeshan Munir Zaib-Un Nisa Muhammad Abu Bakar Saddique Shehzad Mehmood Da Su Chaoyuan Zheng Baoming Ji | 2023 | Journal of Plant Ecology2023,16,2: | 1 |
| 5 | Interference Mitigation in D2D Communication Underlying Cellular Networks:Towards Green Energy显示文摘Device to Device(D2D)communication is emerging as a new participant promising technology in 5G cellular networks to promote green energy networks.D2D communication can improve communication delays,spectral efficiency,system capacity,data off-loading,and many other fruitful scenarios where D2D can be implemented.Nevertheless,induction of D2D communication in reuse mode with the conventional cellular network can cause severe interference issues,which can significantly degrade network performance.To reap all the benefits of induction of D2D communication with conventional cellular communication,it is imperative to minimize interference’s detrimental effects.Efficient power control can minimize the negative effects of interference and get benefits promised by D2D communication.In this work,we propose two power control schemes,Power Control Scheme 1(PCS 1)and Power Control Scheme 2(PCS 2),to minimize the interference and provide performance analysis.Simulation results observe improvements with PCS 1 and PCS 2 as compared to without using any power control scheme in terms of data rate in both uplink and downlink communication modes of Cellular User Equipment(CUE). | Rana Zeeshan Ahamad Abdul Rehman Javed Shakir Mehmood Mohammad Zubair Khan Abdulfattah Noorwali Muhammad Rizwan | 2021 | Computers, Materials & Continua2021,,7: | 0 |
