直接燃烧法与国标煅烧法测定卷烟纸中氧化钙灰分的比较研究

本研究旨在探讨直接燃烧法与国标煅烧法测量氧化钙灰分的差异性,通过配对-t检验法验证两种方法所测结果是否存在显著性差异,结果表明两种方法的测试结果之间存在显著性差异。为了量化两种测试方法的差异,从而更高效、精确地实现生产过程监控卷烟纸灰分含量,对两种方法所测结果进行相关性分析,分析结果表明,两种测试方法之间具有较好的相关性,并拟合出两种方法之间存在显著的如下关系式:国标煅烧法检测氧化钙灰分含量(%)=0.62×直接燃烧法检测碳酸钙灰分含量(%)。     

The comparative evaluation of the nutrient composition and sensory attributes of four vegetables cooked by different methods

The following four vegetables; beans (Phaseolus vulgaris var. vulgaris), brinjal (Solanum melongena var. esculentum), knol‐khol (Brassica oleracea var. caulorapa) and radish (Raphanus raphanistrum satvius) were processed either by conventional, pressure or microwave cooking methods and were analysed for their nutritional and sensory profile. Raw samples were used as controls. Microwave cooking resulted in greater moisture loss when compared with vegetables cooked by other methods. The protein, fat, total ash, calcium, phosphorus, iron, and dietary fibre contents of the vegetables did not differ significantly in raw or cooked vegetables. Ascorbic acid was destroyed to the greatest extent by pressure cooking followed by microwave and conventional method. The sensory attributes of cooked vegetables, as evaluated by a paired preference test, revealed that there were no significant differences between cooked radish and knol‐khol but, in the case of beans and brinjal, microwave and conventionally cooked samples were preferred over pressure cooked ones.     

建设单位安全经理工作压力研究

近年来,安全管理在建设工程管理中越来越受到重视,建设单位新设立“安全经理”岗位进行安全管理工作。由于安全管理作为贯穿施工全过程的管理工作、涉及内容多、工作责任大,并且新设立岗位缺乏相关经验,安全经理目前面临较大的工作压力。采用问卷调研的方法对建设单位安全经理工作压力大小及压力源进行调研,通过均值分析和配对样本t 检验,分别对岗位工作任务压力现状和不同生产阶段的工作压力来源进行了分析。结果表明:安全经理的工作压力主要来源于需要专业技能的日常安全管理工作,即重大危险源管理和安全检查;兼职安全经理的工作压力同时来源于安全管理工作和非安全管理工作,且二者压力值均处于较高水平;开工阶段、基坑阶段和主体施工阶段安全管理工作压力较大,其中钢管脚手架、起重机械、吊篮、危大工程的安全管理工作压力尤为突出。并为缓解建设单位安全经理工作压力提出了针对性建议。     

基于颜色空间的尿毒症诊断研究

由于传统甲诊易受到外界客观因素以及医生主观因素的影响,提出了一套甲象客观采集与信息分析相结合的中医甲诊系统用于尿毒症患者甲象客观化研究。采集并分割了15例尿毒症患者甲象正面照和侧面照,探究维持性血液透析前后甲色变化以及血红蛋白值与各色彩空间数值之间的关系等问题。利用相关分析和多元回归分析等统计学手段,对尿毒症患者血红蛋白值与维持性血液透析前后色彩空间值的关系进行了分析。实验结果表明,尿毒症患者血红蛋白值与多个色彩通道数值有一定的相关性,透析前后多个通道有显著变化,并建立了相关的多元回归方程。     

成对电解同时合成丁二酸和乙醛酸

研究了成对电解新工艺，即在阳极室乙二醛电氧化合成乙醛酸，收率超过７０％；在阴极室顺丁烯二酸电还原合成丁二酸，收率可达８５％。同一电解槽同时获得二种高附加值的产品，并且比旧工艺节约了４０％的电能。该工艺具有投资少，工艺简单，而且无三废排放的特点     

Complete Cototal Roman Domination Number of a Graph for User Preference Identification in Social Media

Many graph domination applications can be expanded to achieve complete cototal domination. If every node in a dominating set is regarded as a record server for a PC organization, then each PC affiliated with the organization has direct access to a document server. It is occasionally reasonable to believe that this gateway will remain available even if one of the scrape servers fails. Because every PC has direct access to at least two documents’ servers, a complete cototal dominating set provides the required adaptability to non-critical failure in such scenarios. In this paper, we presented a method for calculating a graph’s complete cototal roman domination number. We also examined the properties and determined the bounds for a graph’s complete cototal roman domination number, and its applications are presented. It has been observed that one’s interest fluctuate over time, therefore inferring them just from one’s own behaviour may be inconclusive. However, it may be able to deduce a user’s constant interest to some level if a user’s networking is also watched for similar or related actions. This research proposes a method that considers a user’s and his channel’s activity, as well as common tags, persons, and organizations from their social media posts in order to establish a solid foundation for the required conclusion.
