Study on Reproductive Performance of Terapon jarbua(Forsskal,1775)in Tam Giang-Cau Hai Lagoon Systems,Thua Thien Hue Province

Terapon jarbua was collected from Tam Giang-Cau Hai lagoon systems and then their reproductive performances were investigated.Total 342 species were caught by otter trawlers and different fishing gears in marine and Tam Giang-Cau Hai lagoon systems on certain days of each month during period from September 2015 to August 2016 at fishing port.The determination of age was based on composition of the fish:ear,scaly,spine,gill cover and spine and the ovarian histology template.The gonads after being fixed with Bouins solution were cleansed,cut,dyed and put on the observation microscope.Results showed that the sex of Terapon jarbua was nearly clarified at the approximately 1+age group and participated in reproduction process in the first time at the 1+age group.The batch and relative fecundity of Terapon jarbua were high.The batch fecundity of Terapon jarbua varied from 239,029 to 420,400 eggs.The relative fecundity capacity fluctuated from 945 to 1,013 of eggs per gram of fish and the mean value by 981 eggs per gram of fish.The spawning season of fish occurred from March to May annually.

Evaluation of Sponge Gourd(Luffa cylindrical L.)Inbred Lines for Growth Potential and Fruit Quality in Thua Thien Hue Province,Central Vietnam

Plants which contain unisexual flowers are subjected to genetic degradation and yield capacity reduction due to the easily cross-pollination.Sponge gourd,one of species of the Cucurbitaceae which is predominantly cross-pollinating,is cultivated to widely use as vegetable in Vietnamese daily meals.The aim of this experiment was to evaluate the growth potential and fruit quality including fruit aroma of sponge gourd inbred lines.Pure line selection has been performed using self-pollinated method,so that sponge gourd lines would be recovered with high yielding and aroma and thereby recommended for further crop system in Thua Thien Hue province,Central Vietnam.The experiment was conducted in a randomized complete block design(RCBD)with three replications during the winter-spring season in 2017.Agronomical data were observed and analyzed on seven inbred lines(1-MN1,1-MN2,5-MN1,7-MN1,13-MN2,15-MN1 and 15-MN2)derived from B29 accession(GBVN006904).The results indicated that inbred lines 13-MN2,1-MN2 and 15-MN1 attained more highly fruit weight and yield compared to the others.Four inbred lines consisting of 5-MN1,7-MN1,15-MN1 and 15-MN2 still retained the light aroma after boiling.The inbred lines 1-MN2,7-MN1,13-MN2 and 15-MN1 are considered for appropriately using in breeding program of new luffa.

Safe Vegetable Consumption in Hue City:A Case Study of Food Safety Situation in Vietnam

Food safety has become a growing concern for citizens in the modern society when consuming unsafe food that directly impacts public health,life quality and well-being of each country.People of Vietnam in general and specially in Hue city have been facing challenge of vegetable unsafety.A survey concerning the consumption of safe vegetables was conducted in Hue city,Vietnam.Data were collected by using a well-structured questionnaire from representative of 30 consumers,30 producers and 10 collectors.The results showed that lettuce,sweet potato and Chinese mustard were identified as the most important vegetables to consumers in Hue city.Most of the consumers purchased vegetable every day.The cost of vegetable in every transaction was about 30,000 VND.This expenditure has not created a great motivation for developing safe vegetable production.Most of the consumers in Hue city showed high interest,demand,trust and satisfaction for safe vegetable.However,50%of the consumers reported that the price of the safe vegetable was quite expensive and price was not matched with their quality.Moreover,there were some disadvantages in each stage of vegetable supply chain.For example,land,seed,capital,cultivation techniques,preliminary processing,preservation,brand name,trademark and place to consume have not met the requirement of high technology production for the supply chain of safe vegetables.The chain linking between the production and consumption of vegetables is not sustainable.Producers and consumers do not have closely links.Vegetable can not be traced to origin and there is no safe certificate.The consumers believe the quality of vegetables depending on the prestige suppliers,such as,the vegetable shops with foreign consultants.Safe vegetables of farmers are very difficult to be certified for safe vegetables.Solutions and suggestions to Hue city are proposed that it is necessary to establish the vegetable production area in Hue city.Vegetable growers should be supported with capital,knowledge,technology,vegetable preliminary processing and preservation.They should be supported to build a trademark and certificate of vegetable safety and establish the chains of effective safe vegetable consumption.

Soil Gas Radon Measurement for Identifying Active Faults in Thua Thien Hue (Vietnam)

The solid-state nuclear track detectors have long been applied to assess the activity of tectonic faults. We measured the Radon (Rn) concentration in soil gas on 09 profiles with a total of 245 measurement points in Thua Thien Hue area (Vietnam). Measurement results show that the Rn concentration in soil gas ranges from ~10 Bq/m3 to 144,570 Bq/m3. There is a clear difference in the Rn concentration on the granite rock of Dai Loc complex compared to the remaining rocks. The calculated background value and anomaly threshold of Rn concentration on the granite rock of Dai Loc complex and on the remaining rocks are 33,488 Bq/m3, 82,839 Bq/m3 and 5313 Bq/m3, 24,850 Bq/m3 respectively. Spatial distribution of Rn concentration in soil gas reflects the existence of faults since Rn concentration increases at the points above or near fault lines. The level of expression of fault activity is assessed by radon activity index (KRn), which is calculated by the ratio of anomaly value to background value of Rn concentration. According to KRn, in Thua Thien Hue area, only the Dakrong-Hue fault shows a strong expression of activity with high and very high KRn (the maximum KRn = 27.21). The Truong Son, Huu Trach River, Ta Trach River and Bo River fault zones do not show clear activity with low and medium KRn. There is no Rn anomaly value recorded on the Rao Trang fault, demonstrating that it is likely to be inactive at present. The study results indicate that the Rn concentration in soil gas is a strong evidence of the existence of faults or tectonic fracture zones as the Rn concentration always increases at the points above or near the fault line.

中国传统青色与绿色植物染服饰色彩辨析

青绿色系是中国传统服饰色彩中的重要组成部分,其中青色位于传统五正色首位。针对传统服饰色彩中青色与绿色的色彩边界模糊,常常统称为青绿色系的问题,文章首先测量故宫博物院官网上以青绿色命名的清代纺织品的色度值,其次采用传统单染、复染以及与黄色系、红色系植物染料套染等染色技法,对染色后织物的色度值进行测量,比较图片数据与染色实验结果得出我国传统青、绿色系所表示的色度值范围。结果表明:绿色多指出现在第2、3象限的黄绿色,围绕在a轴负值上下,色度值大致范围为a^(*)值≤-10,b^(*)值为-10~50;青色色度值为a^(*)值在-10~10之间,b^(*)值在-70~10范围内,其中L^(*)值较小的一类色彩(-10≤a^(*)、b^(*)值≤10),如石青色、元青色、玄青色等,为狭义的青色。绿色与青色在第3象限有少量交叉。

文本视觉密度与界面色调对老年人数字健康教育的影响研究

数字健康教育以丰富的内容和灵活的教育方式在提升百姓健康素养方面做出了巨大贡献,但由于老年群体认知能力和视觉水平的衰退,在接受数字教育时常面临信息难以识别、理解困难等问题。因此,以数字健康教育平台阅读界面为研究对象,分析了界面视觉设计对老年群体阅读效果和认知负荷的影响。研究中的自变量为文本视觉密度和界面色调,因变量为阅读绩效。2×2双因子实验结果表明:①低文本密度下的阅读理解效果优于标准密度;②冷色调的阅读理解效果优于暖色调;③文本视觉密度与界面色调在阅读时间上存在显著的交互作用。冷色调在标准密度下的阅读用时更少,而暖色调在低密度下的阅读用时更少。研究从健康教育内容传播的视角进行界面设计分析,丰富了老年数字阅读体验数据,探讨了文本视觉密度和色调在界面中的效果与交叉关系,为提升老年人数字教育效能提供了具体设计建议。

血型检测凝集反应结果P-HSV综合判定方法

由于传统血型检测结果的确定取决于有经验的工作人员,使检测效率低下且准确性有待提高。为此,针对微流控血样芯片,首次提出了一种基于图像识别技术的P-HSV(Perimeter-Hue,Saturation,Value)综合判读方法。该方法采用血液凝集反应后的血红细胞凝集尺寸和颜色对血液类型进行综合判读。尺寸判读依据反应腔内凝集块轮廓边缘周长和凝集块数量进行分级,颜色判读依据反应腔内凝集块颜色饱和度(S:Saturation)与明度(V:Value)比值进行分级。根据尺寸和颜色判读结果综合判断凝集反应的等级。由于该方法依据机器视觉原理进行血液凝集反应结果的判断,因此可以快速、准确、客观判断血液类型,杜绝了人为判断的主观性,极大提高了检测速度和准确率。
