The aim of this paper was to analyse the dissolved elements in water which were sampled from the Sebou River in Northern Morocco. The sampling was conducted at the Mechra Bel station for two different hydrological cycles (2013/2013 and 2013/2014). The study was to determine the type of water facies present in the area. The piper diagram shows that the dominant water facies in the area are that of Nacl water facies, which contribute to 56% of the total amount of major elements in the water. The study also revealed that during high water levels, there is dilution of water and during low water levels, the concentration of elements increases. The presence of halite and gypsum bearing rocks in the study area gives an indication that the supply of Na+ and Cl? is related to the dissolution of evaporates. The results also revealed that the specific export of the dissolved load amounts to 127.6 t/km2/year. Finally, the quantification of the dissolved load, through the determination of dissolved material flows shows that the specific export of material amounts to 127.6 t/km2/year.

近年来,随着女性及年轻饮酒人群的不断增加,人们对健康问题和交通安全的重视,无醇葡萄酒越来越受到消费者的青睐,具有良好的发展前景。膜分离、蒸馏脱醇等物理方法常用于无醇葡萄酒生产。然而,乙醇脱除过程中往往伴随着葡萄酒颜色改变及香气损失,使得无醇酒感官品质及消费者对产品的接受程度明显下降。色彩斑斓的可食用花卉不仅具有良好的保健功效,同时也可提高被添加食品的香气、风味和新鲜感。为此,本研究拟在分析反渗透和真空蒸馏脱醇对所得干白、桃红和干红无醇葡萄酒品质的影响的基础上,选择所得最优葡萄酒进行增香试验,探究玫瑰、桃花和百合花对无醇葡萄酒香气和感官品质的影响,以期为无醇葡萄酒增香酿造提供技术支持。试验首先分析了反渗透(RO)和真空蒸馏(VD)两种脱醇方式对霞多丽干白、黑比诺桃红和美乐干红葡萄酒理化参数、挥发性成分和感官质量的影响。结果表明,反渗透和蒸馏均能将所有葡萄酒中的乙醇浓度降低至0.7%v/v,但显著影响了酒的化学成分。脱醇使得葡萄酒p H值、游离二氧化硫、总二氧化硫和挥发性酸含量显著降低,还原糖和总酸含量显著升高。VD处理所得黑比诺桃红和美乐干红葡萄酒的色度值较高,RO处理使得霞多丽干白和美乐干红色泽差异较大。RO酒样中酯类物质(乙酯和乙酸异戊酯),高级醇,脂肪酸,萜烯类和C13-异戊烯类以及羰基化合物含量高于VD酒样。香气活性值分析表明,赋予酒样花香和果香的β-大马士酮是所有酒样中OAV值最高的化合物,但与对照组葡萄酒相比,其在RO和VD处理酒样中的香气强度分别降低了35.54-61.98%和93.62%-97.39%。原始和脱醇酒样最主要的香气系列是果香和花香,但其受VD处理影响很大。感官评价结合主成分分析表明,与VD相比,RO酒样的果香、花香,甜度、粘度和香气强度均较高,VD酒样色泽较高;但2种方法均提高了无醇酒的酸度。综合分析表明,RO无醇葡萄酒更受品尝小组欢迎。在上述试验的基础上,我们将桃花、玫瑰花和百合花提取物(1:200 ml)添加到美乐无醇葡萄酒中,用于改善脱醇所带来的挥发性香气物质及感官品质变化。结果表明,鲜花提取物的添加对无醇葡萄酒理化指标影响不显著,但其挥发性香气物质含量,丙酸乙酯、乙酸异戊酯、己酸乙酯、苯甲酸乙酯、辛酸异戊酯、1-丙醇、芳樟醇、橙花醇、β-大马士革酮和香叶醇等显著增加;而对辛酸和癸酸等呈脂肪、奶酪和酸败味的化合物无显著影响。增香处理显著提高了无醇葡萄酒的香气品质,且与原始酒样的整体接受度相近。香气分析表明,玫瑰和桃花增香美乐无醇葡萄酒的果香和花香、红色水果和香气强度较高,酸度和收敛度适中,甜度升高但低于原始酒样。综合分析表明,上述增香无醇葡萄酒香气强度、果香、花香风味较高,具有较好的风味品质。

Lead zirconate titanate pb(Zr0.50Ti0.50)O3 (pZT) thin films were deposited by a polymeric chemical method on pt(111)/ Ti/SiO2/Si substrates to understand the mechanisms of phase transformations in these films. pZT films pyrolyzed at temperatures higher than 350℃ present a coexistence of pyrochlore and perovskite phases, while only perovskite phase is present in films pyrolyzed at temperatures lower than 300℃. For films where the pyrochlore and perovskite phase coexists the amount of pyrochlore phase decreases from top surface to the bottom film-electrode interface and the pZT structure near top surface are Ti-rich compositions while near the bottom film-electrode interface the compositions are Zr-rich. For pyrochlore-free pZT thin film, a small (100) orientation tendency near the film-electrode interface was observed.

为评价发酵前冷浸渍工艺对桃红起泡葡萄酒品质的影响,以‘黑比诺’葡萄为试材,采用放汁法结合传统瓶内二次发酵技术酿造起泡葡萄酒,探究不同浸渍时间对酒样的起泡特性、理化指标、色泽参数以及风味特征的影响。结果表明:浸渍时间对压力影响不显著,但对泡沫最大高度和稳定时间有显著影响,浸渍24 h,酒样的起泡特性最好;随浸渍时间的延长,酒样的酒精度、色度、pH值与总酚含量显著升高,L^(*)、a^(*)和b^(*)值也呈明显上升趋势,6、12 h与24、36 h酒样的颜色分别以橙色调和红色调为主;浸渍时间对各类化合物含量的影响不同,进而决定酒样的呈香特征及香气品质,12与36 h处理酒样中的酯类、醇类和脂肪酸类化合物含量较高,24 h处理酒样中萜烯及C_(18)-绛异戊二烯类化合物含量较高,上述物质共同构成了桃红起泡葡萄酒的果香、花香和植物味,感官分析也验证了该结果。综合分析表明,发酵前6℃浸渍24 h后放汁更适合‘黑比诺’桃红起泡葡萄酒酿造。

This work deals with the efficient management of industrial liquid discharges from soap factories (ILDS) in the region of Abidjan. The aim of this work is to evaluate the physico-chemical quality of these discharges as well as the different types of pollution generated. Seventeen (17) industrial soap sources were studied through fourteen (14) global pollution parameters (T, pH, electrical conductivity EC, redox potential EH, suspended matter SM, COD, BOD5, biodegradability factor BF, , , , , total iron and ). A liquid waste collection campaign was done during six weeks from February to March 2016, corresponding to a period of intensive activity of these industries. The samples were analyzed according to the norms of the French Standardization Agency (AFNOR). Results were compared with the Ivorian guide values recommended by the Classified Installations Inspection Service (CIIS). principal Component Analysis (pCA) is allowed to evaluate the pollution induced by these factories’ rejection. In addition, Ascending Hierarchical Classification (AHC) method leads to classify soap factories into three groups according to the physico-chemical quality of their releases. Moreover, the estimation of the biodegradability factor is permitted to know the state of the biodegradability of these effluents.

为优化分散液液微萃取(dispersive liquid-liquid microextraction,DLLME)测定葡萄酒中酯类化合物的方法,以模拟葡萄酒为试材,研究分散剂种类及体积、萃取剂种类及体积、样品体积、盐添加质量及萃取时间7个因素对模拟葡萄酒中16种酯类化合物萃取效果的影响,结合单因素和Box-Behnken响应面试验对萃取条件进行优化,并采用气相色谱-质谱(GC-MS)进行定性定量分析。结果表明,模拟葡萄酒中酯类化合物的最佳萃取条件为:分散剂甲醇1200μL,萃取剂二氯甲烷600μL,样品体积7 mL,不添加盐,萃取时间1.0min。在此条件下,16种待测酯类化合物的线性关系良好,R2均高于0.995,检测限(limit of detection,LOD)和定量限(limit of quantitation,LOQ)分别为0.004~0.078 mg/L和0.012~0.261 mg/L;3个质量浓度水平的加标回收率为83.3%~111.3%,日内和日间相对标准偏差(relative standard deviation,RSD)为0.02%~7.69%。对2018—2020年的‘黑比诺’干红葡萄酒和‘贵人香’冰白葡萄酒样品测定时,该方法表现出良好的应用效果,并印证了酯类化合物的种类和质量浓度变化与酒样类型及陈酿年份密切相关。该研究可为深入研究葡萄酒中酯类化合物的代谢提供依据。

Bridges are structures being used to cross rivers, lakes or any other obstacles which involve water. These instruments are commonly used in cities like Recife, which consists of several islands. However, it is common in this city to observe the fast deterioration of these structures that have been built for decades and are subjected to structural recoveries only when they present a possible imminent collapse. The maintenance of these constructions, often used as tourist spots, is essential because of the economic importance, while these structures are responsible for transporting people and cargo, and also play a key role in the city＇s roads. This paper aims to present and assess the conservation status of these bridges through the study of possible pathologies found at princesa Isabel Bridge, Government Agamenon Bridge, ponte Giratória Bridge and paulo Guerra Bridge. The methodology for its inspection will be prescribed by ABNT NBR-9452/86, which provides for ＂Surveys of Concrete Bridges/Viaducts＂. After analysis, it was found that most bridges problems were caused by the presence of moisture that accumulates in bridges due to the absence or malfunction of drainage systems.

The region of Toumodi, located in the heart of the West African Craton, is renowned for its geological complexity. This geochemical study delves into the origin of siliciclastic sediments and the geodynamic context of their formation. The study reveals that Toumodi’s sediments exhibit an intriguing mineralogical composition, with indications of a dual source of parent rocks, one rich in quartz and the other poor in quartz. Furthermore, geochemical analysis highlights a variation in sediment maturity from west to east, indicating the coexistence of distinct geotectonic environments in the region. In the eastern part of the Toumodi region, a passive margin is defined characterized by sediments with an abundance of quartz, while to the west, an active margin is observed with sediments having a lower quartz content. This arrangement suggests the presence of a potential suture zone in the region. This geological complexity underscores the importance of further research to better understand the origin of sediments and the processes that have shaped them. Moreover, this study sheds new light on the fascinating geology of Toumodi, but many questions remain to be explored.
