The anthill soil is used by hypertensive elderly and teenagers from Oshikoto region (Namibia) and many of them testified stabilization of their blood pressure to normal after consuming the anthill soil-derived aqueous extracts. This study therefore investigated and/or assessed the physicochemical parameters, the contents of some metal(loid)s (and their associated potential health risks) and the qualitative composition of bioactive compounds of this anthill soil. The homogenous soil sample collected from various anthill soils in the Oshikoto region was used to obtain the measurements of physiochemical parameters. The elemental contents were determined (using an Inductively Coupled Plasma Optical Emission Spectrophotometer) after acid digestion in accordance with the EPA method 350B and their potential health risk assessments were performed. Methanol, aqueous methanol, and aqueous-based extracts were generated via maceration extraction process prior to the screening of bioactive compounds using standard diagnostic assays. The oxidation reduction potential (164.4 ± 16.6 mV) was the only physicochemical parameter whose value was within the World Health Organization limits for drinking water whereas, total dissolved solids (23 ± 5.5 mg/L), electrical conductivity (44 ± 10.1 uS/cm) and pH (5.35 ± 0.33) were out of specifications. Phenolic compounds, flavonoids, terpenoids, and cardiac glycosides were present in anthill soil (with respect to the extractants used) to which its antihypertensive properties can be attributed in addition to some of the studied mineral components. With respect to the pH, TDS and EC, and the contents of most metal(loid)s in relation to their health risk assessment values, the results suggest that aqueous extracts derived from this anthill soil can be deemed unsuitable for human consumption.

In Brazil, the peanut culture has been expanding mainly in the state of São Paulo, responsible for 80% of the national production. It is an edible culture produces oil of excellent quality, contains proteins rich in amino acids that make up to 36% of weight of the grain. Furthermore, it is associated with nitrogen-fixing bacteria. However, the practice of inoculation is not very common in peanuts, being this species considered susceptible to nodularity with a large number of rhizobia. However, known’s that inoculation with selected strains can increase the efficiency of symbiosis and peanut yield. Thus, the present study was proposed to evaluate the development of peanut inoculated with rhizobia and grown in Cerrado’s Oxisol. The experiment was conducted in a greenhouse, in a completely randomized design, five treatments, one cultivar (IAC 505) and four replicates. The treatments were composed of three strains of rhizobia and two controls, one absolute and the other with nitrogen fertilizer (50 mg⋅N⋅dm3). Each experimental plot has been consisted an 8 dm3 pot with three plants. The inoculation was done, applying 3 mL of bacterial broth (108 mL−1 cells) in the root system of each plant. The SPAD index, number and dry weight of nodules, dry mass of shoots and roots, number and weight of grains were analyzed. The response of Peanuts inoculated was significantly, as all inoculated plants showed similar development to nitrogen-fertilized, emphasizing the potential for supplying nitrogen in peanut development.

Background: The sexual health indices of the adolescents are very poor. This study ascertained the factors influencing the sexual behaviour among female adolescents in Onitsha, Anambra state, Nigeria. Method: This was a cross sectional design in which a total of 800 female adolescents were selected from secondary schools in the area using multistage sampling method;and also selected from a major market (for those who were not at school) in the same geographical area using cluster sampling technique. Data were collected from the respondents about socio-demographic profile, reproductive and sexual health knowledge, attitude, behavior, sources of sexual health information. Result: The highest proportion of students who had ever had sex was found among the 16 - 17 years age group while the modal age group was 18 - 19 years for non students. Also “not living with both parents” and poor family background, were markedly associated with increased likelihood to engage in sexual activity. Poverty level was particularly high among the non-student adolescents. Furthermore, wrong knowledge of fertile period, low risk perception of HIV and premarital, and use of condoms among the respondents were all significantly associated with increased chance to engage in sex. The student adolescents got sexuality information mainly from the teachers;as opposed to their non-student counterparts who had youth organization and friends as main sources. Conclusion: Family values, poverty alleviation, change of attitude through appropriate health and sexuality education especially targeting the non-student adolescents are highly recommended. Sexual negotiation skill, accessible formal education for all should be encouraged to create the right sexual behavior among the adolescent girls.

Maize (Zea mays L.) is the major cereal cultivated in Benin and it is important to know its genetic diversity to improve the yield. The genetic markers of important traits are evaluated in order to improve the maize inbred lines. The aim of this study was to evaluate the genetic diversity of Benin’s maize accessions by SSR marker. Thus, one hundred eighty seven maize accessions from three areas (South, Center and North) were analyzed using three SSR markers. A total of 227 polymorphic bands were produced and showed high genetic diversity (Shannon index = 0.51). The polymorphic information content (PIC) values for the SSR loci ranged from 0.58 to 0.81, with an average of 0.71. Genetic distance-based UPGMA dendrogram showed a genetic differentiation between accessions and they were grouped into four clusters in each area. This work provides necessary information that can be used not only to improve the maize production and conservation but also to better manage genetic species resources in Benin.

供应链运营过程中存在一个普遍质量问题,制造商产品质量的内部可见性很高,在渠道范围内的可见性却很低。因而,供应链内质量信息共享成为质量披露的重要方式,通过质量信息共享可以提高产品质量、减少缺陷,有助于供应链可持续运营。然而,由于担心失去竞争优势、难以超越直接连接的组织进行协调以及现有组织信息系统之间缺乏集成,许多供应链节点企业不愿意共享质量数据。许可区块链技术的出现,有效帮助供应链解决质量信息共享问题。许可区块链提供一种安全的方式帮助供应链的各个层面的节点企业共享数据,同时保护数据隐私。已有研究集中在传统区块链技术在供应链中的应用,较少研究评估或证明更新的、获得许可的区块链解决供应链质量管理问题的能力。本文旨在评估许可区块链解决供应链质量信息共享问题的可行性,并对质量信息共享方案实施过程中核心设计要素进行权衡。基于此,通过设计和构建基于Hyplerledger Fabric(HLF)v2.3许可区块链的概念验证供应链系统和应用程序,并测试其数据访问和机密性,对供应链系统进行应用实施。首先,对区块链技术和HLF许可的区块链平台的背景和概念进行阐述。根据制造供应链运营的实际要求,确定供应链质量信息共享系统的框架,并使用QFD分析,确定系统的设计特征,并根据其能力进行排名。另外,进行竞争分析,与现有的企业信息系统相比,提出能够更好地满足7客户要求中5项的基于区块链的供应链质量信息系统。其次,对排名前5的区块链平台进行了比较分析,根据要求选择HLF。使用QFD分析的输出,设计了一个基于许可的基于区块链的供应链质量信息共享系统,考虑了身份创建方法、每种类型节点的数量、服务器集成、私有数据配置、数据结构设计、智能合约设计和应用设计。基于位于中国、新加坡、美国和德国的4个租用VPS服务器组成的分布式网络,设计系统设置。基于设计的区块链系统对汽车供应链进行了仿真,评估提出的供应链质量信息共享系统的信息共享和隐私保护能力。根据企业实际运营数据,仿真涉及汽车产品的4个组件的设计、订购、制造、检查、运输和交货过程中的质量数据信息。对单个组件和组件质量信息,包括质量制造要求和检验数据,通过各自的供应商和客户门户输入系统,并由供应链的不同成员进行查询。系统仿真结果表明,基于区块链的供应链质量信息共享系统能够提供跨供应链多个层级的质量数据的可见性,同时保护供应链节点企业交易细节不被同一供应链中的竞争对手看到,从而验证了许可区块链解决供应链质量管理问题的潜力。

Journal of Geoscience and Environment Protection 2016年第5期4卷 117-126页

作者： Sylvanus A. Onjefu Nnenesi A. Kgabi simeon H. Taole Owen P. L. Mtambo Charles Grant Johann Antoine Department of Physics and Electronics North-West University Mafikeng Campus Mmabatho South Africa Department of Natural and Applied Sciences Namibia University of Science and Technology Windhoek Namibia Department of Civil and Environmental Engineering Namibia University of Science and Technology Windhoek Namibia Department of Mathematics and Statistic Namibia University of Science and Technology Windhoek Namibia International Centre for Environmental and Nuclear Sciences University of the West Indies Mona Campus Kingston Jamaica

In this study, an occupancy factor model was developed and used to calculate the average time spent for outdoor and indoor activities along the coastline of the Erongo region of Namibia. A closed ended questionnaire was developed and administered to 800 respondents who visited the coastline for leisure, occupational and other activities. The mean time allocated for leisure activities ranges from 13.00 to 1.00 h, occupational mean time between 10.18 to 9.06 h and the values of other activities range from 16.66 to 11.00 h. The average computed time spent outdoor was found to be 11.46 h and indoor calculated to be 12.54 h. This shows an outdoor factor of 0.48 and indoor factor of 0.52 respectively. From the results obtained, the value of the absorbed dose rate ranged from 93.27 to 105.95 nGy·hǃ and the annual effective dose rate ranged from 121.01 to 176.61 μSv·yǃ (UNSCEAR factor) and 292.60 to 413.63 μSv·yǃ (present factor). The values obtained for annual effective dose are higher than the acceptable limit. However, from this study, we can conclude that the use of the UNSCEAR outdoor factor in the coastline will lead to underestimation of effective dose by 24% based on the present factor.
