| 1 | Impact of Nitrogen, Phosphorus and Potassium on Brown Planthopper and Tolerance of Its Host Rice Plants显示文摘The brown planthopper(BPH),Nilaparvata lugens(St?l),appeared as a devastating pest of rice in Asia. Experiments were conducted to study the effects of three nutrients,nitrogen(N),phosphorus(P) and potassium(K),on BPH and its host rice plants. Biochemical constituents of BPH and rice plants with varying nutrient levels at different growth stages,and changes in relative water content(RWC) of rice plants were determined in the laboratory. Feeding of BPH and the tolerance of rice plants to BPH with different nutrient levels were determined in the nethouse. Concentrations of N and P were found much higher in the BPH body than in its host rice plants,and this elemental mismatch is an inherent constraint on meeting nutritional requirements of BPH. Nitrogen was found as a more limiting element for BPH than other nutrients in rice plants. Application of N fertilizers to the rice plants increased the N concentrations both in rice plants and BPH while application of P and K fertilizers increased their concentrations in plant tissues only but not in BPH. Nitrogen application also increased the level of soluble proteins and decreased silicon content in rice plants,which resulted in increased feeding of BPH with sharp reduction of RWC in rice plants ultimately caused susceptible to the pest. P fertilization increased the concentration of P in rice plant tissues but not changed N,K,Si,free sugar and soluble protein contents,which indicated little importance of P to the feeding of BPH and tolerance of plant against BPH. K fertilization increased K content but reduced N,Si,free sugar and soluble protein contents in the plant tissues which resulted in the minimum reduction of RWC in rice plants after BPH feeding,thereby contributed to higher tolerance of rice plants to brown planthopper. | Md Mamunur RASHID Mahbuba JAHAN Khandakar Shariful ISLAM | 2016 | Rice science2016，23，3： | 12 |
| 2 | Power generation expansion planning approach considering carbon emission constraints显示文摘Decarbonization of the power sector in China is an essential aspect of the energy transition process to achieve carbon neutrality.The power sector accounts for approximately 40%of China’s total CO_(2) emissions.Accordingly,collaborative optimization in power generation expansion planning(GEP)simultaneously considering economic,environmental,and technological concerns as carbon emissions is necessary.This paper proposes a collaborative mixedinteger linear programming optimization approach for GEP.This minimizes the power system’s operating cost to resolve emission concerns considering energy development strategies,flexible generation,and resource limitations constraints.This research further analyzes the advantages and disadvantages of current GEP techniques.Results show that the main determinants of new investment decisions are carbon emissions,reserve margins,resource availability,fuel consumption,and fuel price.The proposed optimization method is simulated and validated based on China’s power system data.Finally,this study provides policy recommendations on the flexible management of traditional power sources,the market-oriented mechanism of new energy sources,and the integration of new technology to support the attainment of carbon-neutral targets in the current energy transition process. | Hasan Mehedi Xiaobin Wang Shilong Ye Guiting Xue Islam Md Shariful Fang Shi | 2023 | Global Energy Interconnection2023，6，2： | 1 |
| 3 | Unmet needs for mental care services for older people in Bangladesh during the COVID-19 pandemic显示文摘Dear Editor We read with interest the editorial by Qiu et at about the psychological distress among the general population in China during the COVID-19 pandemic and policy recommendations.The elderly are more vulnerable to increased mental health problems during COVID-19,which has raised significant challenges for community mental health services.12 Older people with comorbid conditions,including cardiovascular diseases,lung diseases,diabetes and hypertension are more likely to be severely affected and die because of COVID-19,which is caused by SARS-CoV-2.^(3). | Md Sazedur Rahman Md Ashfikur Rahman Laila Afroze Sheikh Mohammed Shariful Islam | 2020 | General Psychiatry2020，33，6： | 0 |
