Characterization of planting materials used as adsorbent has been studied in order to compare potassium ion adsorption on two types of planting materials, which are a fired planting material （FPM） made from a mixture of 4 kinds of wastes （bottom ash, flue gas desulfurization （FGD） gypsum, paddy soil and sawdust） formed and fired at 850 ℃and the commercial planting material called ＂hydroball＂（HDB） bought from Jatujak market, Bangkok. The physical characteristics of both types of planting materials indicate that the FPM has a larger specific surface area than the HDB. The factors affecting potassium adsorption on both the planting materials such as an equilibration time and some solid/solution ratios were investigated. The suitable equilibration time for the adsorption to reach an equilibrium on the FPM and HDB is one and two hours, respectively. The highest amounts of potassium ion adsorbed on both the planting materials were obtained when the solid/solution ratio was 1 ： 15. The adsorption behavior on both the planting materials tends to correspond with the Freundlich isotherm.

Objectives:This study aimed to determine the predictors of health-promoting behaviour among older adults with hypertension in Bengkulu City,Bengkulu,***:A cross-sectional study was conducted in 333 older adults with hypertension,who were selected using multistage sampling *** were obtained by face-to-face interview with structured *** questionnaires used in this study included the Health-Promoting Lifestyle Profile II(HPLP II),Hypertension Knowledge-Level Scale(HK-LS),Self-Rated Abilities for Health Practices Scale(SRAHP),Barriers to Health-promoting Behaviour Scales(BAS),Benefits to Health-Promoting Behaviour Scales(BES),Multidimensional Scale of Perceived Social Support(MSPSS)and Situational Influences Questionnaire(SIQ).Data were analysed by using multiple linear ***:The mean and standard deviation(Mean±SD)of each questionnaire were as follows:HPLP II,2.55±0.19;HK-LS,11.83±3.00;SRAHP,2.00±5.87;BAS,27.89±2.70;BES,34.29±2.29;MSPSS,60.35±8.12;and SIQ,47.71±*** to the multiple linear regression model,36.9% of the variation in health-promoting behaviour among older adults with hypertension can be explained by six variables,namely,education,knowledge,self-efficacy,perceived barriers,social support and situational influences(adjusted R^(2)=0.369).Conclusions:High and good-quality education will increase the level of health-promoting behaviour,whereas barriers,such as expense and time requirement,can decrease *** influences and support from family and friends can also influence the older adult's attempts to change their health *** self-efficacy will clearly result in improved health-promoting behaviour of older adults with hypertension.

大豆种子成熟至收获期间如遇高温高湿天气,种子活力及活性会急剧下降,这就是所谓的田间老化(field weathering)。田间老化是热带、亚热带地区大豆生产的主要限制因素之一。本研究旨在寻找与田间老化性状相连锁的DNA标记并将其应用于辅助选择育种。为此,利用修改的培养箱老化法和人工控制老化法对大豆品种Chiangmai 60(敏感),GC10981(抵抗)及其F2群体(139个体)进行了鉴定。在两种处理条件下,F2代群体的种子发芽率及活性均为正态分布,说明大豆种子田间老化抗性受多个基因控制。根据F2代个体的种子发芽率及活性,6个高抗个体及7个高感个体的DNA分别被混合为抗性池和感性池,并利用AFLP标记进行了混合群体分析(BulkSegregant Analysis)。从扩增的2162个标记中,发现了5个可能于大豆种子田间抗性相连锁的片段。通过DNA克隆和测序,设计了5对引物用于从大豆总DNA中扩增相应的片段。其中3对引物扩增的片段差异太小或未能扩增正确大小的片段,没能用于F2群体。引物Eaag/Mcac-233和Eact/Mctt-157能扩增出差异明显的多态性,通过对F2代群体的分析,这2个标记属同一连锁群,遗传距离为25.8c M。QTL分析结果显示有一个QTL位于这两个标记之间,距Eaag/Mcac-233约14c M,可以解释29.7%的变异。用这两对引物对整个F2群体进行筛选,20个个体属于抗性群体,结合抗性鉴定的结果,7个个体被用于与Chiangmai60进行回交。18个BC1F1个体(41·9%)的抗性高于其亲本的平均值。说明这些标记进行可以被用于大豆田间老化抗性的辅助筛选研究。
