| 4 | Source identification, contamination status and health risk assessment of heavy metals from road dusts in Dhaka, Bangladesh显示文摘In this study, concentrations of Cr, Mn, Ni, Cu, Zn, Cd and Pb were determined in road dusts collected from different locations in Dhaka to assess source, contamination status and health risk. Energy-dispersive X-ray fluorescence spectroscopy and energy-dispersive X-ray spectroscopy were used to determine Cr, Mn, Ni, Cu, Zn, Cd and Pb and their mean concentrations were 162.27 ± 29.46, 721.18 ± 180.14, 35.65 ± 12.55, 104.56 ± 128.33, 515.32 ± 321.90,BDL, and 342.82 ± 591.20 mg/kg, respectively. Among the heavy metals, highest concentrations of Cu, Zn and Pb were found at urban sites-7(municipal waste dumping) and 8(medical waste incineration). Highest concentration of Cr followed by Cu and Zn was found at site-5(Tejgaon, urban). Principal component analysis revealed that anthropogenic activities are the potential sources for Cr, Ni, Cu, Zn and Pb while earth crust for Mn. Pollution index and pollution load index results suggested that all the sites were contaminated and/or degraded by Cr, Cu, Zn and Pb except sites-9(urban), 10(sub-urban), 11(rural) while sites-7 and 8(urban) were extremely degraded. For noncarcinogenic health risk, hazard quotient values for dermal were higher compared to that of inhalation/ingestion. Though hazard index values were less than 1 at all the sites, these were at least one order of magnitude higher for children group than that of adult group, thus the children group may face more noncarcinogenic health risk at sites -7 and 8. Values of incremental lifetime cancer risk were from 10to 10showed no carcinogenic health risk by road dusts contaminated with the heavy metals. | Aklima Nargis Ahsan Habib Md Nazrul Islam Kai Chen Md Shafiqul Islam Sarker A N M Al-Razee Wenbin Liu Guorui Liu Minggang Cai | 2022 | Journal of Environmental Sciences2022，34，11： | 3 |
| 5 | Real-time visual inspection system for grading fruits using computer vision and deep learning techniques显示文摘Traditional manual visual grading of fruits has been one of the important challenges faced by the agricultural industry due to its laborious nature as well as inconsistency in inspec-tion and classification process.Automated defects detection using computer vision and machine learning has become a promising area of research with a high and direct impact on the domain of visual inspection.In this study,we propose an efficient and effective machine vision system based on the state-of-the-art deep learning techniques and stack-ing ensemble methods to offer a non-destructive and cost-effective solution for automat-ing the visual inspection of fruits’freshness and appearance.We trained,tested and compared the performance of various deep learning models including ResNet,DenseNet,MobileNetV2,NASNet and EfficientNet to find the best model for the grading of fruits.The proposed system also provides a real time visual inspection using a low cost Raspberry Pi module with a camera and a touchscreen display for user interaction.The real time sys-tem efficiently segments multiple instances of the fruits from an image and then grades the individual objects(fruits)accurately.The system was trained and tested on two data sets(apples and bananas)and the average accuracy was found to be 99.2% and 98.6% using EfficientNet model for apples and bananas test sets,respectively.Additionally,a slight improvement in the recognition rate(0.03% for apples and 0.06% for bananas)was noted while applying the stacking ensemble deep learning methods.The performance of the developed system has been found higher than the existing methods applied to the same data sets previously.Further,during real-time testing on actual samples,the accuracy was found to be 96.7% for apples and 93.8% for bananas which indicates the efficacy of the developed system. | Nazrul Ismail Owais A.Malik | 2022 | Information Processing in Agriculture2022，9，1： | 3 |
| 6 | In vivo anticancer activity of vanillin semicarbazone显示文摘Objective:To evaluate the anticancer activity of vanillin semicarbazone(VSC) against Ehrlich ascites carcinoma(EAC) cells in Swiss albino mice.Methods:The compound VSC at three doses(5, 7.5 and 10 mg/kg i.p.) was administered into the intraperitoneal cavity of the EAC inoculated mice to observe its efficiency by studying the cell growth inhibition, reduction of tumour weight,enhancement of survival time as well as the changes in depleted hematological parameters. Allsuch parameters were also studied with a known standard drug bleomycin at the dose of 0.3 mg/kg(i.p.).Results:Among the doses studied, 10 mg/kg(i.p.) was found to be quite comparable in potency to that of bleomycin at the dose of 0.3 mg/kg(i.p.). The host toxic effects of VSC was found to be negligible.Conclusions:It can be concluded that VSC can therefore be considered as potent anticancer agent. | Shaikh M Mohsin Ali M Abul Kalam Azad Mele Jesmin Shamim Ahsan M Mijanur Rahman Jahan Ara Khanam M Nazrul Islam Sha M Shahan Shahriar | 2012 | Asian Pacific Journal of Tropical Biomedicine2012，2，6： | 2 |
| 7 | 强场预磁化对高浊度黏土污水混凝沉降的影响显示文摘高浊度矿物污水难以高效澄清处理的主要原因之一是黏土矿物颗粒表面荷电且包覆有一层“水化膜”,使得矿物颗粒凝聚、絮凝困难。为了提升高浊度污水的混凝澄清效果,降低化学药剂用量,将强场预磁化处理引入混凝沉降过程,采用预磁化-混凝沉降工艺处理高浊度黏土污水。通过单因素变化试验及多因素正交试验,研究了磁场强度、磁化时间等预磁化工艺参数及药剂制度对黏土污水澄清效果的影响。研究结果表明,强磁场作用对高浊度黏土污水的性质具有显著影响,从而使得污水的混凝澄清效果显著提升。黏土絮团的平均沉降速度增大1.92倍,沉降20min时的尾泥体积减少38.9%,上清液透光率提高54.1%。预磁化最佳的磁场强度范围为178~241mT。磁场强度减小,磁化效果迅速减弱;磁化强度增加,磁化效果无明显增强。预磁化最佳的磁化时长为90s左右。在获得同等澄清效果的情况下,预磁化-混凝沉降比常规混凝沉降的絮凝剂用量减少了50%,CaCl2用量减少了75%。同时,最终尾泥体积反而减小了14.65%。机理分析表明,强场预磁化对矿粒表面的双电层结构及水分子排列构型具有较大影响,从而显著减小了zeta电位减小、减薄了矿粒表面的水化膜。矿粒表面性质的改善可以显著提升黏土矿粒的凝聚效率、促进矿粒与絮凝剂分子的结合,从而提升了高浊度黏土污水的混凝效果。本工作为高泥化矿物污水的澄清处理提供了一种绿色高效的新方法。 | 李建军 朋许杰 谢蔚 戎鑫 Islam Nazrul 乔尚元 朱金波 | 2019 | 煤炭学报2019，44，7： | 2 |
| 8 | Reproductive development of two groundnut cultivars as influenced by boron and light显示文摘Boron is an important micronutrient that enhances reproductive growth of crops such as groundnut.Light also plays an important role for pegging of groundnut.There has been little information on the application of boron and light in groundnut in Bangladesh.A field experiment was conducted to study the effects of boron and light on the reproductive development of two groundnut cultivars.Treatments considered as two groundnut cultivars,viz.,‘Dhaka-1(C1)’and‘BARI Chinabadam-8(C2)’,three levels of boron(B),viz.,0-kg B ha^-1(B0),1-kg B ha^-1(B1)and 2-kg B ha^-1(B2),and two levels of light,viz.,normal day light(≈12-h light)and normal day light+6-h extended red light at night(≈18-h light).Result revealed that the reproductive development,yield and shelling percentage of groundnut were markedly increased with the application of B.Due to imposition of light all of reproductive units increased but decrease number of pods and pod yield.The highest reproductive unit and yield were observed from‘BARI Chinabadam-8’.Therefore,reproductive development could be improved by application of boron in improved cultivars(BARI Chinabadam-8)but not for under extended light. | Md.Quamruzzaman Md.Jafar Ullah Md.Fazlul Karim Nazrul Islam Md.Jahedur Rahman Md.Dulal Sarkar | 2018 | Information Processing in Agriculture2018，5，2： | 2 |
| 9 | Sinapic acid ameliorates D-galactosamine/lipopolysaccharideinduced fulminant hepatitis in rats:Role of nuclear factor erythroidrelated factor 2/heme oxygenase-1 pathways显示文摘BACKGROUND Sinapic acid(SA)has been shown to have various pharmacological properties such as antioxidant,antifibrotic,anti-inflammatory,and anticancer activities.Its mechanism of action is dependent upon its ability to curb free radical production and protect against oxidative stress-induced tissue injuries.AIM To study the hepatoprotective effects of SA against lipopolysaccharide(LPS)/Dgalactosamine(D-GalN)-induced acute liver failure(ALF)in rats.METHODS Experimental ALF was induced with an intraperitoneal(i.p.)administration of 8μg LPS and 800 mg/kg D-GalN in normal saline.SA was administered orally once daily starting 7 d before LPS/D-GalN treatment.RESULTS Data showed that SA ameliorates acute liver dysfunction,decreases serum levels of alanine transaminase(ALT),and aspartate aminotransferase(AST),as well as malondialdehyde(MDA)and NO levels in ALF model rats.However,pretreatment with SA(20 mg/kg and 40 mg/kg)reduced nuclear factor kappalight-chain-enhancer of activated B cells(NF-κB)activation and levels of inflammatory cytokines(tumor necrosis factor-αand interleukin 6).Also,SA increased the activity of the nuclear factor erythroid-related factor 2/heme oxygenase-1(Nrf2/HO-1)signaling pathway.CONCLUSION In conclusion,SA offers significant protection against LPS/D-GalN-induced ALF in rats by upregulating Nrf2/HO-1 and downregulating NF-κB. | Mushtaq Ahmad Ansari Mohammad Raish Yousef A Bin Jardan Ajaz Ahmad Mudassar Shahid SheikhFayaz Ahmad Nazrul Haq Mohammad Rashid Khan Saleh A Bakheet | 2021 | World Journal of Gastroenterology2021，27，7： | 2 |
