This research investigates and report petrological features and geochemical characteristics of igneous rocks in Ado-Ekiti, Southwestern Nigeria. Exhaustive geological fieldwork reveals Ado-Ekiti is underlain by migmatite-gneiss, quartzite, granite (porphyritic and fine-grained) and charnockite. Petrographic investigation revealed overwhelming presence of quartz, biotite and plagioclase in all the rocks while microcline and opaque minerals occur in subordinate amounts. Average SiO2 content in porphyritic granite (74.56 %) is marginally higher than charnockite (73.51%) and fine-grained granite (70.41%). These values correlate well with previous works in the study area and agrees with similar rocks in other parts of the country. Analytical results using Phillips Panalytical PW1480 X-ray Fluorescence Spectrometer with Rhodium Tube as the X-ray source revealed the siliceous nature of the rocks. The binary plot (Na2O+K2O) vs SiO2 established the rocks are granitic with all the samples plotting within granite field. AFM ternary diagram shows the rock have calc-alkaline affinity. Geochemical classification by (Na2O + K2O-CaO) vs SiO2 diagram reveals the rocks are “Calc-alkalic and calcic”. The elevated K2O (average of 4.41%) in the data signaled High-K calc-alkaline type on K2O vs SiO2 binary diagram. Alumina Saturation Index (ASI) showed the rocks are metaluminous while Al2O3 / (Na2O + K2O) vs Al2O3/ (Na2O +K2O +CaO) plot suggest the rocks have mantle origin
研究报告了尼日利亚西南部Ado-Ekiti地区火成岩的岩石学特征和地球化学特征。详尽的地质野外调查显示,Ado-Ekiti的下垫层为混杂岩片麻岩、石英岩、花岗岩(斑岩和细粒)和绿帘岩。岩石学调查显示,石英、黑云母和斜长石在所有岩石中占绝大多数,微斜长石和不透明矿物次之。斑岩花岗岩SiO2平均含量为74.56%,略高于绿绿岩(73.51%)和细粒花岗岩(70.41%)。这些值与研究地区以前的工作相吻合,并与该国其他地区的类似岩石相一致。采用Phillips Panalytical PW1480 x射线荧光光谱仪,以铑管为x射线源,分析结果揭示了岩石的硅质性质。Na2O+K2O / SiO2二元图确定岩石为花岗质,所有样品均在花岗质范围内。AFM三元图显示岩石具有钙碱性亲和关系。地球化学分类(Na2O + K2O-CaO) vs SiO2图显示岩石具有“钙碱性和钙性”特征。在K2O / SiO2二元图上,数据中K2O升高(平均为4.41%)为高钾钙碱性。Al2O3/ (Na2O +K2O)与Al2O3/ (Na2O +K2O +CaO)比值图表明岩石具有幔源性

The concept of biological studies is divided into four levels of representation, namely macroscopic, microscopic, molecular, and symbolic levels. The interconnection of these four levels makes a major contribution to the development of students' mental models in building the meaning and conceptual understanding of biological materials. Mental models are ideas in the minds of students that are used to develop, explain, and predict a phenomenon. The formation of mental models is influenced by the experiences they have, their confidence or selfefficacy, and the problems they face. Multiple representations are believed to influence the formation of mental models and students' self-efficacy. For this reason, an in-depth study of the role of multiple representations in building mental models and students' self-efficacy is needed. This research is qualitative research with descriptive analysis techniques and a literature review (library research). The analysis is carried out by reviewing articles that are relevant to the study being discussed. In the search for articles, four keywords were used, namely: multiple representation learning, biology learning, mental models, and self-efficacy. The articles used in this study were 25 international articles obtained from Google Scholar and ERIC. From the results of the study, it was found that learning multiple representations is very effective in building mental models and self-efficacy in biology students. From the results of this study, it is recommended for lecturers and teachers to use multiple representations learning in the learning process to build mental models and self-efficacy in students.
生物学研究的概念分为宏观、微观、分子和符号四个层次的表征。这四个层次的相互联系对学生构建生物材料的意义和概念理解的心智模式的发展作出了重大贡献。心理模型是学生头脑中用来发展、解释和预测现象的想法。心理模式的形成受到他们所拥有的经验、他们的信心或自我效能以及他们所面临的问题的影响。多元表征影响心理模型的形成和学生的自我效能感。因此,有必要深入研究多重表征在心理模型构建和学生自我效能感中的作用。本研究是定性研究与描述分析技术和文献综述(图书馆研究)。分析是通过审查与正在讨论的研究相关的文章来进行的。在文章检索中,使用了四个关键词:多重表征学习、生物学习、心理模型和自我效能感。本研究使用的文献为来自Google Scholar和ERIC的25篇国际文献。从研究结果来看,学习多重表征对生物学生的心理模型和自我效能感的建立非常有效。从本研究的结果来看,建议讲师和教师在学习过程中使用多重表征学习来建立学生的心理模型和自我效能感。

An education continuum plan was unveiled by the Department of Education (2020) as soon as schools resumed their operations and acknowledged the key contribution that parents can make to the academic achievement of their children. Hence, this paper sought to explore parental participation in the completion of science academic tasks using the Husserlian Transcendental phenomenology approach. The result revealed six (6) emerging themes of the parents' lived experience; (1) parents’ educational background and ability limit their involvement in Science learning tasks; (2) social media sites and online games hamper science learning tasks productivity; (3) navigating multifaceted challenges in the new-normal education; (4) technology and the internet as a game-changer in the completion of Science learning tasks; (5) moral and emotional support as a way to encourage; and (6) discipline and ensuring a healthy working environment at home. Based on the findings, the school must provide parents with intervention strategies that meet their demands, including household instructional strategies and behavior management approaches for circumstances when children are learning at home.
学校一恢复运营,教育部就公布了一项教育持续计划(2020年),并承认父母可以为孩子的学业成就做出关键贡献。因此,本文试图利用胡塞尔的先验现象学方法来探讨父母在完成科学学术任务中的参与。结果揭示了六(6)个新兴主题的父母的生活经验;(1)父母的教育背景和能力限制了他们参与科学学习任务;(2)社交媒体网站和网络游戏阻碍了科学学习任务的生产力;(3)应对教育新常态下的多重挑战;(4)科技和互联网在完成科学学习任务中起着改变游戏规则的作用;(5)以道德和情感支持作为鼓励的方式;(6)纪律严明,确保家庭工作环境健康。基于研究结果,学校必须为家长提供满足他们需求的干预策略,包括家庭教学策略和儿童在家学习时的行为管理方法。

This study intended to assess the water quality of a River in terms of the abiotic factors and bacterial analysis. Sampling stations were established through transect sampling. The abiotic factors or the physico-chemical parameters recorded from the river were found to be very supportive for the total well-being of the water and the aquatic organisms alike: water velocity (0.36 m/s) is smooth and temperature (23.18 oC) is on average that make both parameters “essential” to support the life cycle of organisms known to indicate a good water quality; pH level (7.14) is average/”satisfactory” for a fresh water; and turbidity (17.95 NTU) is rated as excellent. The bacterial analysis indicated that the water of Dahilayan River, Manolo Fortich, Bukidnon, Phils. contains bacteria that make the water not potable. It is then concluded that the Dahilayan River is still in good condition as it projects onstandard-levels of abiotic factors or the physico-chemical parameters, however the streams’ bacterial content makes the water not potable
本研究拟从非生物因素和细菌分析两方面对某河流水质进行评价。通过样条抽样建立采样站。从河流中记录的非生物因素或物理化学参数被发现非常支持水和水生生物的总体健康:水流速度(0.36 m/s)平滑,温度(23.18 oC)平均,使这两个参数对支持生物体的生命周期“必不可少”,已知表明良好的水质;淡水的pH值(7.14)为平均/“满意”;浊度(17.95 NTU)被评为优秀。细菌分析表明,菲律宾布基德农市马诺洛·福蒂奇市达希拉延河的水含有大量细菌。含有细菌,使水不适合饮用。由此得出的结论是,大希拉延河的状况仍然良好,因为它的非生物因素或物理化学参数达到了标准水平,但河流的细菌含量使水不适合饮用

Lipocalin-2 (LCN2), also known as neutrophil gelatinase associated lipocalin, has been identified as a crucial iron protein that impedes bacterial growth during physiological and inflammatory states. In recent times, the oncological impact of LCN2 has been extensively studied in various cancer types, including colorectal cancer, gastric cancer, prostate cancer, breast cancer, and pancreatic cancer. Different levels of LCN2 have been linked to increased cell proliferation, angiogenesis, cell invasion, and metastasis. Consequently, LCN2 has emerged as a promising therapeutic target against various cancer types. This review consolidates the most notable findings on the expression, biological functions, and regulation of LCN2, along with the proteins with which LCN2 interacts in cancer.
脂载蛋白-2 (lipocalin -2, LCN2),也被称为中性粒细胞明胶酶相关脂载蛋白,已被确定为在生理和炎症状态下阻碍细菌生长的关键铁蛋白。近年来,LCN2在各种癌症类型中的肿瘤学影响已被广泛研究,包括结直肠癌、胃癌、前列腺癌、乳腺癌和胰腺癌。不同水平的LCN2与细胞增殖、血管生成、细胞侵袭和转移增加有关。因此,LCN2已成为一种有希望的治疗多种癌症的靶点。这篇综述整合了关于LCN2的表达、生物学功能和调控以及与LCN2在癌症中相互作用的蛋白的最显著的发现。

BONYAN theory and method indicate being committed, accepted, and responsible as effective and constructive for "how to be with what is," and is presented in the form of the experiential marathon group. This study investigates the effect of online participation in the BONYAN-method experiential marathon group (BMEMG) on the quality of life of the non-clinical populations.This study was a quasi-experimental design of two heterogeneous groups, the experimental group (N=50) and the control group (N=98), with pre-test and post-test. The program was held over three days with three weekly follow-up sessions. Before the start and after the third follow-up session, WHOQOL-100 was provided to the two groups. The physical, psychological, level of independence, social relationships, environment, personal beliefs, generality, and overall score in the experimental group's post-test significantly differed from the experimental group's pre-test and the control group's post-test. The effect size was significant for all indices, among which spirituality and independence showed the highest effect size.The BMEMG, by providing opportunities for awareness of "how to be with what is," confronts people with their internal and dynamic psychological patterns and improves their quality of life by increasing their capacity for acceptance and flexibility.
BONYAN的理论和方法表明,承诺、接受和负责是“如何与什么是”有效和建设性的,并以体验马拉松小组的形式呈现。本研究探讨在线参与bonyan方法体验马拉松组(BMEMG)对非临床人群生活质量的影响。本研究采用准实验设计,分为实验组(N=50)和对照组(N=98)两组,分为前测和后测。该项目为期三天,每周有三次后续会议。在第三次随访开始前和结束后,分别向两组提供WHOQOL-100。实验组的后测在生理、心理、独立性、社会关系、环境、个人信仰、共性、总分等方面均与实验组前测和对照组后测存在显著差异。各指标的效应量均显著,其中精神性和独立性的效应量最高。BMEMG通过提供机会让人们意识到“如何与现状相处”,使人们面对他们内在的和动态的心理模式,并通过增加他们的接受能力和灵活性来提高他们的生活质量。

The study investigated relationship between competence-based digital literacy concepts and management of primary school curriculum implementation in Embu County Kenya. Competence based curriculum digital literacy emphasizes development of digital skills, knowledge and core competences in learners’ real life situation, in Kenya. However, competence-based curriculum implementation is insufficiently managed following limited digital technology use in schools; rising concern on effectiveness of competence based learning activities in Kenyan schools. The objective of the study is to determine relationship between competence-based digital literacy concepts and management of primary school curriculum implementation in Embu County, Kenya. The study involved 364 respondents using purposive and simple random techniques. The study employed correlation research design. The study respondents were: competence-based classroom teachers, subject panel heads, senior teachers, head teachers and deputy head teachers. The data collection tools were questionnaires and interview guides for head teachers, deputy head teachers, subject panel heads, senior teachers and competence based classroom teachers. The descriptive statistics was presented in frequencies and percentages; while inferential statistics was analyzed using regression statistic technique. The study reviewed that most school managers have integrated in teaching and learning the current and emerging digital technologies to support curriculum delivery and management; as well as managing and creating information in the immediate digital environment. The study established that digital technologies enable provision of individualized learning management system for teachers. The study indicated that there is significant relationship between competence-based digital literacy concepts and management of primary school curriculum implementation in Embu County, Kenya. Following study findings, the researcher concludes that competence-based digital literacy concepts are crucial in management of primary school curriculum implementation in Kenyan schools. Therefore, the researcher recommends that ministry of education should promote digital literacy technologies for efficient curriculum implementation management in primary schools in Kenya.
