Certain peculiarities of inelastic nonlinearity of unconsolidated near surface stressed granular media contributed at micro- scale are investigated to ascertain anomalous time dependent strength behaviour macro-effects, with geotechnical/geo-environmental implications. Comparative examination of ultrasonic P- and S-wave pulse stimulated repeatable displacement response wave-forms of confined dry and fully saturated ceramic grains analogue, endorsable by pertinent theory, hint certain persistive time and frequency restricted occurrences vouching vital insights. Examination aimed at both understanding “louder” response of “quieter” seismic and aseismic events in granular sediments, and imparting enhanced conceptual substantiation of some previously published results, show that subtle acoustic emission and/or stick-slip type micro events do occur, and, when spread over time and/or space are collectively capable of altering granular material macro strength behaviour. It is clearly deducible from resonant type spectral results that material fragmentation or force chain formation type phenomenon occurs possibly due to macro-scale friction mobilization by grain scale events. It is further speculated that invisible high frequency events may irreversibly alter grain scale surface properties and/or intergranular friction as enhanced elasticity type effect, more elusive with saturation. Temporal morphology of stick-slip type events when stimulated by P- and S-wave modes is posited to be non-identical in characteristic sense.
在微观尺度上研究了松散近表面应力颗粒介质的非弹性非线性的某些特性,以确定异常的随时间变化的强度行为宏观效应,具有岩土工程/地质环境意义。超声P波和s波脉冲刺激的受限干燥和完全饱和陶瓷颗粒模拟可重复位移响应波形的对比研究,得到了相关理论的支持,暗示了某些持续的时间和频率限制事件,提供了重要的见解。研究旨在理解颗粒沉积物中“较小”地震和地震事件的“较大”响应,并对先前发表的一些结果进行强化的概念证实,表明细微的声发射和/或粘滑型微事件确实发生,并且随着时间和/或空间的扩散,它们共同能够改变颗粒材料的宏观强度行为。从共振型光谱结果可以清楚地推断,材料破碎或力链形成型现象的发生可能是由于晶粒尺度事件的宏观摩擦动员所致。进一步推测,不可见的高频事件可能以增强弹性型效应不可逆地改变晶粒尺度表面性质和/或晶间摩擦,随着饱和度的增加,这种效应更加难以捉摸。在P波和s波刺激下,粘滑型事件的时间形态在特征意义上是不相同的。

数据集太大、太复杂,无法使用标准方法或工具进行操作或查询,因此无法使用一些常规方法进行处理。如今,社交网络、移动电话、传感器和科学为每天产生的数据贡献了100字节。网络搜索引擎的创建者是最先面对这个问题的人之一。我们都听过很多关于“大数据”的说法,但“大”实际上是一个转移注意力的词。电信和其他以数据为中心的行业等公司长期以来一直拥有庞大的数据集。存储容量不断扩大,今天的“大”肯定是明天的“中”,下周的“小”,或者可以定义为“大数据”是当数据本身的大小成为问题的一部分。对大量数据进行研究以揭示隐藏模式和秘密关联的过程,称为大数据分析。我们讨论的数据问题从千兆字节到拍字节不等。这些有用的信息有助于公司或组织获得更丰富、更深入的见解,并在竞争中获得优势。因此,需要尽可能准确地分析和执行大数据实施。在某种程度上,处理数据的传统技术已经失去了动力。信息平台类似于传统的数据仓库,但又有所不同。一些丰富的api是为探索和理解数据而设计的,而不是用于传统的分析和报告。——————————  ——————————

The increased number of glucose in the blood is called Diabetes [7] and is forecasted to be a very major disease by 2030. [7] There is a pressing need to explore better remediation, be it in form of synthetic or naturally occurring chemicals. This paper made an exploratory investigation on the hypoglycemic effect of a common food item known as ―okra‖ or Abemoschus esculentus (EA). Six (6) mice were randomly selected and grouped into 2 groups and were given extracts from the fruit of Abelmoschus esculentus (EA)/okra which was chopped into three pieces and was soak in 250ml potable water overnight. 1 st group is the Control Group and the 2 nd group is the Treatment Group. Average results of the two (2) groups are determined and recorded upon conducting this experimental research. The Control Group has an average result of 94mg/dl in the 1 st test, 99mg/dl in the 2 nd test, 94mg/dl in the 3 rd test, 101mg/dl in the 4 th test, 97mg/dl in the 5 th test and 73mg /dl in the 6 th test. The Treatment Group has an average result of 87mg/dl in the 1 st test, 99mg/dl in the 2 nd test, 124mg/dl in the 3 rd test, 129mg/dl in the 4 th test, 115mg/dl in the 5 th test and 88mg/dl in the 6 th test. Results indicated that the extract from Abelmoschus esculentus (EA)/okra has hypoglycemic effect and no observable changes in behavior are noticed to the mice. It is recommended to replicate the study with more number of mice and longer observation period.
血液中葡萄糖含量的增加被称为糖尿病[7],预计到2030年将成为一种非常重要的疾病。[7]迫切需要探索更好的补救措施,无论是用合成的还是自然产生的化学品。本文对一种常见的食品——秋葵‖(Abemoschus esculentus, EA)的降糖效果进行了探索性研究。随机选取6只小鼠,分为2组,分别给予Abelmoschus esculentus (EA)/秋葵果实提取物,切成3段,用250ml饮用水浸泡过夜。第一组为对照组,第二组为治疗组。在进行本实验研究时,确定并记录两组的平均结果。对照组第1次试验平均为94mg/dl,第2次试验为99mg/dl,第3次试验为94mg/dl,第4次试验为101mg/dl,第5次试验为97mg/dl,第6次试验为73mg /dl。治疗组第1次试验平均为87mg/dl,第2次试验为99mg/dl,第3次试验为124mg/dl,第4次试验为129mg/dl,第5次试验为115mg/dl,第6次试验为88mg/dl。结果表明,秋葵提取物具有降血糖作用,对小鼠行为无明显影响。建议增加小鼠数量,延长观察时间,重复本研究。

The corrosion inhibitive action of oxystelma esculentum stem on mild steel corrosion in 0.5 M H2SO4 solution was studied using weight loss method, potentiodynamic polarization and EIS measurements. The results obtained indicate that the extracts functioned as good inhibitors in 0.5 M H2SO4 solution. Inhibition efficiency was found to increase with extract concentration. The adsorption of constituents in the plant extract on the surface of the metal is proposed for the inhibition behavior.

Assessing The Adequacy Of Split-Plot Design Models 评估分块设计模型的充分性
Pub Date : 2013-06-25 DOI: 10.1504/IJDS.2016.10002333
David, Asiribo, Dikko
This paper assesses the adequacy of model fit of the split-plot design models, that is the whole plot (WP) sub-design model with WP error and the split-plot (SP) sub-design model with SP error for comparing the effectiveness of resistant measures that use medians instead of means, resulting in a coefficient that is more resistant to outliers or extreme data points. This paper presents empirical application of four measures of model adequacy check and they are coefficient of determination (R2), modelling efficiency (MEF) statistic, prediction coefficient of determination (R2prod), and mean square error prediction (MSEP). These four measures were explored using their mean and median form. A 2(1+3) replicated two-level SP design and a 31 × 42 replicated mixed level SP design were used for computing the measures of model adequacy of fit for each WP and SP sub-design models. These measures in their median form described the predictive performance of each WP and SP sub-design models adequately.
本文评估了分裂图设计模型的模型拟合充分性,即带有WP误差的整图(WP)子设计模型和带有SP误差的分裂图(SP)子设计模型,用于比较使用中位数而不是平均值的抵抗措施的有效性,从而得出一个更能抵抗异常值或极端数据点的系数。本文给出了模型充分性检验的四个测度的实证应用,即决定系数(R2)、建模效率(MEF)统计量、预测决定系数(R2prod)和均方误差预测(MSEP)。这四项措施是用它们的平均值和中位数形式来探讨的。采用2(1+3)重复双水平SP设计和31 × 42重复混合水平SP设计计算每个WP和SP子设计模型的模型拟合充分性。这些测量的中值形式充分描述了每个WP和SP子设计模型的预测性能。

Healthcare Waste Management; Its Impact: A Case Study Of The Greater Accra Region, Ghana. 医疗废物管理;其影响:以加纳大阿克拉地区为例。
Pub Date : 2013-03-13 DOI: 10.2139/SSRN.2410909

Hospital waste management is an imperative environmental and public safety issue, due to the waste’s infectious and hazardous character. In recent years, hospital waste management has become a growing issue of concern with the increasing evidence suggesting health hazards related to health care waste (HCW) inflicted upon the service providers, patients and the community as a whole. Ghana, a developing country, has little information on the healthcare waste generate, how it is handle, and its disposal. The study analyzed the healthcare waste management practices in the Greater Accra Region, Ghana. The study involved 120 healthcare centers in the region. A total of 150 healthcare estate officers and waste management workers. Site visits, interviews, and survey questionnaires were implemented to collect information regarding different medical waste management aspects, including medical waste generation, separation, collection, storage, transportation, and disposal. Results from the study shows 8221.2kg waste per bed per day {1.2kg bed-1 day-1 *6,851 beds} are generated. An analysis per the population size of Ghana (25 million) as against a projection estimate by 2025 shows that, healthcare waste will increase greatly, hence the need for strategic focus on it management as accepted internationally. Comparing the finding of the waste generation rate to other studies Greater Region of Ghana has a much higher generation rate of healthcare waste. In conclusion, healthcare centers in the Greater Accra Region do not abide to the accepted healthcare waste management policy of Ghana. It is recommended that laws of best standard of healthcare waste management should be passed and enforced by the Ministry of Local Government, to improve the current situation and to protect the environment and human health.
由于医院废弃物具有传染性和危险性,医院废弃物管理是一个迫切需要解决的环境和公共安全问题。近年来,医院废物管理已成为一个日益受到关注的问题,越来越多的证据表明,与医疗废物有关的健康危害对服务提供者、患者和整个社区造成了危害。加纳是一个发展中国家,几乎没有关于医疗废物产生、处理和处置的信息。该研究分析了加纳大阿克拉地区的医疗废物管理做法。这项研究涉及该地区的120个医疗中心。共有150名保健屋邨主任及废物管理人员。通过实地考察、访谈和问卷调查,收集医疗废物管理不同方面的信息,包括医疗废物的产生、分类、收集、储存、运输和处置。研究结果显示,每天每张床产生8221.2kg废物{1.2kg床-1天-1 * 6851张床}。根据加纳人口规模(2500万)与2025年的预测估计数进行的分析表明,医疗保健废物将大大增加,因此需要将战略重点放在国际公认的信息技术管理上。将废物产生率的发现与其他研究进行比较,加纳大区域的医疗废物产生率要高得多。总之,大阿克拉地区的医疗保健中心不遵守加纳公认的医疗废物管理政策。建议地方政府部通过并执行关于医疗废物管理最佳标准的法律,以改善现状,保护环境和人类健康。
