| 1 | Ti-Mo-Sn合金显微组织、力学性能和形状记忆性能(英文)显示文摘研究Mo作为β相稳定元素,对Ti-Mo-Sn合金相组成、显微组织、力学性能和形状记忆性能的影响。通过电弧熔炼法制备不同成分的Ti-xMo-3Sn(x=2,4,6,摩尔分数,%)合金,并制备二元合金Ti-6Mo作为对照组。Ti-xMo-3Sn合金具有硬度低和韧性高(厚度可减少90%)的特点,而Ti-6Mo合金则表现出脆性行为,硬度高、韧性差。场发射扫描电镜(FESEM)下发现圆形的无热ω(ωath)析出相。X射线衍射结果也证实铸态和固溶处理-淬火态的样品中均存在ωath相。光学显微镜和FESEM结果显示,由于发生β→ω相变,淬火过程中形成的马氏体数量随着Mo含量的增加而降低。硬度的变化趋势也证实ωath相的存。Ti-6Mo-3Sn合金的形状记忆效应(SME)最高,为9%。合金SME较低是由于形成ωath相;然而,SME随着Mo含量的增加而增加,这是由于ωath相的逆相变和由压力引起的马氏体相变所致。另外,设计一种新的、非常简单的测量形状记忆效应的方法。 | Muhammad Luqman HASHMI Abdul WADOOD | 2020 | Transactions of Nonferrous Metals Society of China2020,30,3: | 8 |
| 2 | Impacts of different drying strategies on drying characteristics,the retention of bio-active ingredient and colour changes of dried Roselle显示文摘The drying kinetics of Roselle(Hibiscus sabdariffa L) of variety Terengganu(UMKL-1) and the quality attribution of Roselle were studied. The experiments were conducted using four different drying methods, including solar greenhouse drying(SD), solar greenhouse with intermittent heat pump drying(SIHP), hot air drying(HA) and heat pump drying(HP). Among the four drying methods, HP achieved the highest drying rate at a range from0.054 g H_2 O·(g DM)^(-1) ·min^(-1) to 0.212 g H_2 O·(g DM)^(-1)·min^(-1) while SD had the lowest drying rate, measured at 0.042 g H_2 O·(g DM)^(-1)·min^(-1).The analysis on colour kinetics revealed that there is no significant colour loss(p > 0.05) observed from HP's dried Roselle. Greater amount of flavonoid compounds i.e. protocatechuic acid was found in SD and SIHP dried finished product whereas HP's dried Roselle contains higher percentage of catechin as compared to other drying methods. | Thing Chai Tham Mei Xiang Ng Shu Hui Gan Lee Suan Chua Ramlan Aziz Luqman Chuah Abdullah Sze Pheng Ong Nyuk Ling Chin Chung Lim Law | 2018 | Chinese Journal of Chemical Engineering2018,26,2: | 7 |
| 3 | Identification of key gene networks controlling organic acid and sugar metabolism during watermelon fruit development by integrating metabolic phenotypes and gene expression profiles显示文摘The organoleptic qualities of watermelon fruit are defined by the sugar and organic acid contents,which undergo considerable variations during development and maturation.The molecular mechanisms underlying these variations remain unclear.In this study,we used transcriptome profiles to investigate the coexpression patterns of gene networks associated with sugar and organic acid metabolism.We identified 3 gene networks/modules containing 2443 genes highly correlated with sugars and organic acids.Within these modules,based on intramodular significance and Reverse Transcription Quantitative polymerase chain reaction(RT-qPCR),we identified 7 genes involved in the metabolism of sugars and organic acids.Among these genes,Cla97C01G000640,Cla97C05G087120 and Cla97C01G018840(r^(2)=0.83 with glucose content)were identified as sugar transporters(SWEET,EDR6 and STP)and Cla97C03G064990(r^(2)=0.92 with sucrose content)was identified as a sucrose synthase from information available for other crops.Similarly,Cla97C07G128420,Cla97C03G068240 and Cla97C01G008870,having strong correlations with malic(r^(2)=0.75)and citric acid(r^(2)=0.85),were annotated as malate and citrate transporters(ALMT7,CS,and ICDH).The expression profiles of these 7 genes in diverse watermelon genotypes revealed consistent patterns of expression variation in various types of watermelon.These findings add significantly to our existing knowledge of sugar and organic acid metabolism in watermelon. | Muhammad Jawad Umer Luqman Bin Safdar Haileslassie Gebremeskel Shengjie Zhao Pingli Yuan Hongju Zhu M.O.Kaseb Muhammad Anees Xuqiang Lu Nan He Chengsheng Gong Wenge Liu | 2020 | Horticulture Research2020,7,1: | 4 |
| 4 | Landslide inventory and susceptibility assessment using multiple statistical approaches along the Karakoram highway,northern Pakistan显示文摘China-Pakistan Economic Corridor(CPEC)is a framework of regional connectivity,which will not only benefit China and Pakistan but will have positive impact on Iran,Afghanistan,India,Central Asian Republic,and the region.The surrounding area in CPEC is prone to frequent disruption by geological hazards mainly landslides in northern Pakistan.Comprehensive landslide inventory and susceptibility assessment are rarely available to utilize for landslide mitigation strategies.This study aims to utilize the high-resolution satellite images to develop a comprehensive landslide inventory and subsequently develop landslide susceptibility maps using multiple techniques.The very high-resolution(VHR)satellite images are utilized to develop a landslide inventory using the visual image classification techniques,historic records and field observations.A total of 1632 landslides are mapped in the area.Four statistical models i.e.,frequency ratio,artificial neural network,weights of evidence and logistic regression were used for landslide susceptibility modeling by comparing the landslide inventory with the topographic parameters,geological features,drainage and road network.The developed landslides susceptibility maps were verified using the area under curve(AUC)method.The prediction power of the model was assessed by the prediction rate curve.The success rate curves show 93%,92.8%,92.7%and 87.4%accuracy of susceptibility maps for frequency ratio,artificial neural network,weights of evidence and logistic regression,respectively.The developed landslide inventory and susceptibility maps can be used for land use planning and landslide mitigation strategies. | Mian Luqman HUSSAIN Muhammad SHAFIQUE Alam Sher BACHA CHEN Xiao-qing CHEN Hua-yong | 2021 | Journal of Mountain Science2021,18,3: | 4 |
| 5 | Mutation of the PHYTOENE DESATURASE 3 gene causes yellowish-white petals in Brassica napus显示文摘Oilseed rape (Brassica napus) with yellow flowers is an attractive ornamental landscape plant during the flowering period,and the development of different petal colors has become a breeding objective.Although yellowish flower color is a common variant observed in field-grown oilseed rape,the genetics behind this variation remains unclear.We obtained a yellowish-white flower (ywf) mutant from Zhongshuang 9 (ZS9) by ethyl methanesulfonate mutagenesis (EMS) treatment.Compared with ZS9,ywf exhibited a lower carotenoid content with a reduced and defective chromoplast ultrastructure in the petals.Genetic analysis revealed that the yellowish-white trait was controlled by a single recessive gene.Using bulked-segregant analysis sequencing (BSA-seq) and kompetitive allele-specific PCR(KASP),we performed map-based cloning of the ywf locus on chromosome A08 and found that ywf harbored a C-to-T substitution in the coding region,resulting in a premature translation termination.YWF,encoding phytoene desaturase 3 (PDS3),was highly expressed in oilseed rape petals and involved in carotenoid biosynthesis.Pathway enrichment analysis of the transcriptome profiles from ZS9 and ywf indicated the carotenoid biosynthesis pathway to be highly enriched.Further analyses of differentially expressed genes and carotenoid components revealed that the truncated Bna A08.PDS3 resulted in decreased carotenoid biosynthesis in the mutant.These results contribute to an understanding of the carotenoid biosynthesis pathway and manipulation of flower-color variation in B.napus. | Chuanji Zhao Luqman Bin Safdar Meili Xie Meijuan Shi Zhixue Dong Li Yang Xiaohui Cheng Yueying Liu Zetao Bai Yang Xiang Chaobo Tong Junyan Huang Lijiang Liu Shengyi Liu | 2021 | The Crop Journal2021,9,5: | 3 |
| 6 | 中性和酸性溶液中Q235碳钢表面沉积植酸转化膜的耐蚀行为研究显示文摘分别在中性和酸性植酸溶液中制备植酸转化膜并研究其耐蚀性。结果表明,在中性植酸溶液中得到的植酸转化膜的耐蚀性优于在酸性溶液中得到的植酸转化膜,特别是在0.06 mol/L、pH值为7.0的植酸溶液中反应1 h所得到的植酸转化膜的保护效率可达到96.7%。虽然植酸转化膜与Q235碳钢电极表面通过物理吸附相结合,但是其仍然具有优良的界面结合力。XPS结果表明,植酸具有钝化碳钢表面的功能,且最终在碳钢表面得到的植酸转化膜实际上是一层由植酸转化膜和碳钢表面的Fe_2O_3钝化膜构成的复合膜,二者通过协同抑制作用来保护碳钢电极不受外界腐蚀介质的侵蚀。 | 郝永胜 Luqman Abdullahi SANI 宋立新 徐国宝 葛铁军 方庆红 | 2016 | 中国腐蚀与防护学报2016,36,6: | 3 |

| 8 | Kaolin-based geopolymers with various NaOH concentrations显示文摘Kaolin geopolymers were produced by the alkali-activation of kaolin with an activator solution (a mixture of NaOH and sodium silicate solutions). The NaOH solution was prepared at a concentration of 6-14 mol/L and was mixed with the sodium silicate solution at a Na2SiO3 /NaOH mass ratio of 0.24 to prepare an activator solution. The kaolin-to-activator solution mass ratio used was 0.80. This paper aimed to analyze the effect of NaOH concentration on the compressive strength of kaolin geopolymers at 80℃for 1, 2, and 3 d. Kaolin geopolymers were stable in water, and strength results showed that the kaolin binder had adequate compressive strength with 12 mol/L of NaOH concentration. When the NaOH concentration increased, the SiO2/Na2O decreased. The increased Na2O content enhanced the dissolution of kaolin as shown in X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) analyses. However, excess in this content was not beneficial for the strength development of kaolin geopolymers. In addition, there was the formation of more geopolymeric gel in 12 mol/L samples. The XRD pattern of the samples showed a higher amorphous content and a more geopolymer bonding existed as proved by FTIR analysis. | C.Y. Heah H. Kamarudin A.M. Mustafa Al Bakri M. Bnhussain M.

| 9 | 不同地被菊品种对镉的富集特性及生理响应显示文摘为从地被菊中筛选出耐镉品种并应用于城市园林绿化,采用水培法对14种地被菊在20 mg/L镉胁迫下的富集特性进行了研究。按照镉胁迫下不同地被菊品种耐镉性和富集转移特性的强弱进行聚类分析,可将14个品种分为4类:第1类为L9502(B)、粉翎(D)、白玉(E)、纽9716(J)品种,富集转移较强但耐性弱;第2类为纽9722(K)、紫秋裳(L)品种,耐性较强但富集转移弱;第3类为纽9713(A)、红艳艳(H)、纽9717(M)、紫妍(N)品种,富集转移弱且耐性弱;第4类为东林瑞雪(C)、战地黄花(F)、袖珍红(G)、纽9714(I)品种,富集转移强且耐性强。对东林瑞雪(C)、战地黄花(F)、袖珍红(G)、纽9714(I)品种进行不同浓度镉的胁迫,结果表明:在低浓度(10,20 mg/L)下4种地被菊地上干重下降不明显(P>0.05),高浓度时下降显著(P<0.05);随着镉浓度的升高,4种地被菊根部、地上部镉含量均不断增加;富集系数呈现下降趋势,但都大于1;转移系数呈现F、G、I下降,C上升的趋势;光合参数Pn、Gs、Tr随着镉浓度的提高均显著下降,而Ci则上升,说明镉处理对地被菊光合作用的限制可能是由非气孔因素引起,并没有使叶片气孔发生结构和功能的改变。 | 孙婕妤 Muhammad luqman 李强 何淼 周蕴薇 | 2018 | 吉林农业大学学报2018,40,1: | 3 |
| 10 | Experimental Study on Cross-Flow Induced Vibrations in Heat Exchanger Tube Bundle显示文摘Vibration in heat exchangers is one of the main problems that the industry has faced over last few decades. Vibration phenomenon in heat exchangers is of major concern for designers and process engineers since it can lead to the tube damage, tube leakage, baffle damage, tube collision damage, fatigue, creep etc. In the present study, vibration response is analyzed on single tube located in the centre of the tube bundle having parallel triangular arrangement(60°) with P/D ratio of 1.44. The experiment is performed for two different flow conditions. This kind of experiment has not been reported in the literature. Under the first condition, the tube vibration response is analyzed when there is no internal flow in the tube and under the second condition, the response is analyzed when the internal tube flow is maintained at a constant value of 0.1 m/s. The free stream shell side velocity ranges from 0.8 m/s to 1.3 m/s, the reduced gap velocity varies from 1.80 to 2.66 and the Reynolds number varies from 44500 to 66000. It is observed that the internal tube flow results in larger vibration amplitudes for the tube than that without internal tube flow. It is also established that over the current range of shell side flow velocity, the turbulence is the dominant excitation mechanism for producing vibration in the tube since the amplitude varies directly with the increase in the shell side velocity. Damping has no significant effect on the vibration behavior of the tube for the current velocity range. | KHUSHNOOD Shahab NIZAM Luqman Ahmad | 2017 | China Ocean Engineering2017,31,1: | 3 |
