The aim of the present study is examined by various modeling and self-potential (SP) techniques which are useful for the exploitation of shallow and deep deposits. In the present study area, 12 areas conducted the self-potential techniques. From that analysis, a v-shaped formation was formed, as may be the geological formation of an ore anomaly. The study area's highest millivolt values (30 to 50 mV) indicate the presence of quartz, feldspar, and negative values are associated with the mica group of minerals. The Nellore schist belt is majorly dominated by the schistose group of rocks. The schistose group of rocks has a density very less like 5 to 10 MV. This study would be helpful for various arenas, including exploration geologists and mineralogists.
本研究的目的是通过各种建模和自电位(SP)技术对浅层和深层矿床的开采进行研究。在本研究区域内,有 12 个区域采用了自电位技术。通过分析,形成了一个 V 形地层,这可能是矿石异常的地质构造。研究区域的最高毫伏值(30 至 50 mV)表明存在石英和长石,负值则与云母类矿物有关。内洛尔片岩带主要以片岩组岩石为主。片理岩组的密度非常低,只有 5 到 10 MV。这项研究将对包括勘探地质学家和矿物学家在内的各个领域有所帮助。

Moral Vagueness: Does Mathematics Have a Practical Solution? 道德模糊:数学有实用的解决方案吗?
Pub Date : 2024-04-15 DOI: 10.32388/p1e4vy
Sergei Korchevoi
If one favors Moral Intuitivism in order to deal with Skeptical argument, then thinking by analogy with mathematical knowledge is of use. A major objection to the mathematical analogy in Moral epistemology is the threat of moral relativism in practical applications of moral pluralism if we employ mathematical pluralism as a vector to proceed. Thus, the advocacy for moral pluralism faces an obstacle which should be addressed: a problem of moral «vague» predicates. This article addresses moral vagueness and considers objections toward several treatments of related Sorties series through possibility of deepening a proper mathematical intuition. However, the issue of human moral competency cannot be erased from the picture. It is a critical question for morality which very likely falls beyond the scope of Moral epistemology.
如果我们赞成道德直觉主义以应对怀疑论,那么用数学知识进行类比思考就会有用武之地。对道德认识论中的数学类比的一个主要反对意见是,如果我们把数学多元论作为前进的矢量,那么在道德多元论的实际应用中就会面临道德相对主义的威胁。因此,倡导道德多元论面临着一个需要解决的障碍:道德 "模糊 "谓词问题。本文探讨了道德模糊问题,并通过深化适当数学直觉的可能性,考虑了对相关索蒂斯数列的几种处理方法的反对意见。然而,人类的道德能力问题不能被抹杀。这是道德的一个关键问题,很可能超出了道德认识论的范畴。

Water samples were collected at 3 slope positions (upper, middle and lower) from four locations practising irrigation agriculture in Minna as follows; Fadikwe, Mechanic village in keterin-gwari, Soje-A in kpakungu and Bali in Chanchaga and fitted to a Completely Randomized Design (CRD) having slope positions as replicates for each treatment. Water sampling, Physical and chemical properties and Fungi population and diversity were determined using standard methods. Data generated were subjected to Analysis of Variance (ANOVA) and means were separated using Least Significance Differences (LSD) and Duncan Multiple Range Test. Result obtained revealed that Chanchaga irrigation water recorded the highest fungi population of 1.6 x 107 CFU/ml why fungi diversity was the least at Chanchaga. The presence of _Geotrichum species_ (2.33 x 106CFU/ml), _Candida tropicalis_ (4.33 x 106CFU/ml) and _Torulopsis glabrata_ (1.67 x 106CFU/ml) in water obtained from Mechanic village may be due to the presence of hydrocarbons in the oil polluting the water. They are potential degraders of crude oil hydrocarbons. They may therefore be responsible for the value of Biochemical Oxygen Demand of 261 mg/l recorded at Mechanic village. The Biochemical Oxygen Demand values of 342 mg/l and 360.00mg/l recorded at Fadikwe and Soje A respectively may be due to the presence of _Aspergillus niger.Aspergillus niger_ is a utility biological indicator of level of degradation of pollutant. These values were however higher than the Food and Agriculture organisation (FAO) standards for irrigation water. Further studies should however be carried out to investigate the bioremediating potentials of the fungi species identified in irrigation water obtained from Chanchaga.
在明纳的四个灌溉农业区(Fadikwe、keterin-gwari 的 Mechanic 村、kpakungu 的 Soje-A 和 Chanchaga 的 Bali)的三个斜坡位置(上、中、下)采集水样,并采用完全随机设计(CRD),每个处理以斜坡位置为重复。水样、物理和化学特性以及真菌数量和多样性均采用标准方法进行测定。对所得数据进行了方差分析(ANOVA),并使用最小显著性差异(LSD)和邓肯多元范围检验法对均值进行了区分。结果显示,昌查加灌溉水中的真菌数量最高,为 1.6 x 107 CFU/ml,而昌查加灌溉水中的真菌多样性最低。在 Mechanic 村的水中出现 _Geotrichum species_(2.33 x 106CFU/ml)、_Candida tropicalis_(4.33 x 106CFU/ml)和 _Torulopsis glabrata_(1.67 x 106CFU/ml),可能是由于石油中的碳氢化合物污染了水质。它们是原油碳氢化合物的潜在降解者。因此,它们可能是造成 Mechanic 村生化需氧量达到 261 毫克/升的原因。Fadikwe 和 Soje A 的生化需氧量分别为 342 毫克/升和 360.00 毫克/升,这可能是由于黑曲霉的存在。不过,这些数值高于联合国粮农组织(FAO)的灌溉用水标准。不过,还应该开展进一步研究,以调查从昌查嘎灌溉水中发现的真菌物种的生物修复潜力。

Examining the Relationship of Chapter 1 to Other Chapters in a Dissertation or Thesis 研究第 1 章与学位论文或毕业论文中其他章节的关系
Pub Date : 2024-04-15 DOI: 10.32388/ziw1uw

The review examined the relationship between Chapter 1 and its subsequent Chapters in a dissertation or thesis, informed by a constructivist paradigm utilising a qualitative approach. It further demonstrated how the contrasting ontological, epistemological assumptions and models of human beings the researcher brings to the research process have direct implications for one’s methodological concerns in a project. To ascertain these philosophical assumptions, thirty postgraduate projects were purposively selected and theoretical saturation determined the sample as depth was sought employing a grounded theory.  Different Chapter 1s of various dissertations and theses were scrutinised first and used to develop a framework of analysis which was later fine-tuned using literature surveyed. Guided by an interactive process combining the elements of content and inductive thematic analysis, the major components of the study were identified, namely; the research problem, objectives, sub-problems or hypotheses. In turn, these influenced the literature surveyed, research methodology utilised, analysis and interpretation of data, conclusions drawn and recommendations made. These technicalities if carefully observed are meant to guide postgraduate students to produce a quality product independently and reveal the symbiotic relationship that exists between Chapter 1 and its subsequent Chapters in a dissertation or theses.
在采用定性研究方法的建构主义范式的指导下,本综述探讨了学位论文或毕业论文中第一章与后续章节之间的关系。它进一步证明了研究者在研究过程中对本体论、认识论的假设和人类模式的不同理解如何对项目中的方法论问题产生直接影响。为了确定这些哲学假设,我们有目的性地选择了三十个研究生项目,并采用基础理论寻求深度,从而确定了理论饱和度样本。 首先对各种学位论文和毕业论文的不同第一章进行了仔细研究,并利用这些论文和毕业论文制定了一个分析框架,随后利用所调查的文献对该框架进行了微调。在内容分析和归纳主题分析相结合的互动过程的指导下,确定了研究的主要组成部分,即研究问题、目标、子问题或假设。这些内容反过来又影响了所调查的文献、所使用的研究方法、对数据的分析和解释、所得出的结论以及所提出的建议。这些技术细节如果得到认真遵守,就能指导研究生独立完成高质量的产品,并揭示学位论文或毕业论文中第一章与后续章节之间存在的共生关系。

James Athanasou
The purpose of this report is to introduce the _Work Ability Index_ to a rehabilitation audience and to provide some background on its scope and features. As an indication of its popularity, (a) it is available in 26 languages; (b) it has been applied for more than twenty years and (c) from 1991 there are 388 records including “Work Ability Index” in PubMed. A summary of the data from 29 previous studies of 31,472 participants is provided and it indicated an overall mean of 38.94. Overall this mean would be categorised as a “good” work ability index. As expected, studies of rehabilitation or illness samples indicate “poor” work ability. Each of the 10 questions in the assessment is introduced. The conceptual nature of work ability is reviewed and some issues are raised about the validity of the scoring of the assessment. A conceptual framework for the work ability process is outlined.

Utilising Creative Storytelling to Raise 6th-Grade Primary School Students’ Awareness About Children’s Rights 利用创意故事提高六年级小学生对儿童权利的认识
Pub Date : 2024-04-15 DOI: 10.32388/099zxb
N. Lambropoulos, Elisavet Ntriza
Education for the Children’s Rights has been developed for formal and non-formal education, utilising diverse pedagogical methodologies for Primary Education. Creative Storytelling supports students in externalising and communicating their thoughts, feelings, and experiences through their stories, actively participating in each other worlds via empathy, freeing them from their real and stressful action environment. Thus, in this case study, a creative storytelling teaching scenario based on the Hero’s Journey is proposed to contribute to 6th-grade Greek Primary School students’ learning about Children’s Rights and the dual role of child labour as a cause and consequence for school dropout. The results from the mixed research methodology suggested that raising awareness was successful and the students managed to create stories advancing their knowledge and awareness about Children’s Rights Education. However, the case study and the number of students are limited; more research is needed for results generalizability and validity.
儿童权利教育是针对正规和非正规教育开发的,利用了小学教育的各种教学方法。创意讲故事支持学生通过故事外化和交流他们的思想、情感和经验,通过移情积极参与彼此的世界,将他们从现实和紧张的行动环境中解放出来。因此,在本案例研究中,我们提出了一个基于《英雄之旅》的创意故事教学情景,以帮助希腊小学六年级学生了解儿童权利以及童工作为辍学原因和后果的双重作用。混合研究方法的结果表明,提高认识活动取得了成功,学生们成功地创作了故事,增进了他们对儿童权利教育的了解和认识。然而,由于案例研究和学生人数有限,还需要开展更多研究,以确保结果的普遍性和有效性。

INTRODUCTION: Delta radiomics is a tool used to assess the response of oncologic patients undergoing immunotherapy. It extracts high-dimensional quantitative features from medical images, providing information about cancer's phenotype, genotype, and tumoral microenvironment. This analysis could help avoid invasive procedures and help choose the most suitable therapeutic in multiple therapeutic options.METHOD: Radiomics has gained interest as an imaging biomarker for predicting response to various immunotherapies. Delta radiomics assesses feature variations from one time point to another based on subsequent images, offering higher value for treatment-outcome prediction or patient stratification into risk categories.CONCLUSION: It has potential benefits for clinical endpoints in oncology, such as differential diagnosis, prognosis, treatment response prediction, and evaluation of side effects. Further research with prospective and multicentre studies is needed for clinical validation of delta radiomics approaches.STATEMENT OF CLINICAL SIGNIFICANCE: In head and neck oncology, delta radiomics can be used to enhance the precision of diagnosis, assess tumor response, forecast normal tissue toxicity, predict clinical outcome, and pinpoint characteristics for treatment modification. Patients' quality of life may be enhanced by it. It can support post-treatment surveillance. Additionally, it can support the delivery of individualized care based on a patient's reaction to medication and radiation.
简介:德尔塔放射组学是一种用于评估接受免疫疗法的肿瘤患者反应的工具。它从医学影像中提取高维定量特征,提供有关癌症表型、基因型和肿瘤微环境的信息。方法:放射组学作为预测对各种免疫疗法反应的成像生物标志物,已经引起了人们的兴趣。德尔塔放射组学根据后续图像评估从一个时间点到另一个时间点的特征变化,为治疗结果预测或患者风险分层提供更高的价值。结论:它对肿瘤学的临床终点具有潜在的益处,如鉴别诊断、预后、治疗反应预测和副作用评估。临床意义说明:在头颈部肿瘤学中,δ放射组学可用于提高诊断的精确度、评估肿瘤反应、预测正常组织毒性、预测临床结果,以及准确定位治疗调整的特征。患者的生活质量也会因此得到提高。它可以支持治疗后监测。此外,它还可以根据病人对药物和放射治疗的反应提供个性化护理。

On n-Dimensional Maxwell and Dirac Equations in Curved Space-Time and Its Applications in SO(P,Q) Group Theoretic Image Processing 论弯曲时空中的 n 维麦克斯韦和狄拉克方程及其在 SO(P,Q) 群论图像处理中的应用
Pub Date : 2024-04-12 DOI: 10.32388/lz87yf.2
H. Parthasarathy
Maxwell equations in p time and q spatial dimensions are formulated. Properties of the Green’s function for the associated (p,q)-wave operator are derived based on contour integration.

BACKGROUND AND OBJECTIVES: Camellia sinensis is a tree popularly called green tea used as a strong antioxidant and for treating diseases such as cancer. This present study was aimed at assessing the phytochemicals and evaluating the hepatoprotective activity of leaf extract in Wistar rats. METHODS: The phytochemical screening was performed by standard methods, acute toxicity study and hepatoprotective activity were evaluated in randomly groups of five rats or six rats in paracetamol-induced liver toxicity. RESULTS: The phytochemical screening of leaf extract revealed the presence of major metabolites. The GC-MS analysis showed 18 bioactive compounds which are mainly fatty acids with retention times between 7.436 and 18.462 min. A high total phenolic content (TPC) of 1425.22 mg GAE/g and a total flavonoid content (TFC) of 802.01 mg QE/g were obtained. The acute toxicity did not produce any sign of toxicity at a dose of 5,000 mg/kg of extract. The extract produced a dose-dependent activity on the liver. These protections were statistically significant (p<0.05) when compared to the standard drug silymarin. There were no elevated values in liver function biomarkers in all the animal groups as well as histopathological damages to the liver after eight weeks of treatment at 200 and 400 mg/kg b.w. of extract doses. CONCLUSION: In conclusion, the study showed that C. sinensis methanol leaf extract contains important phytochemicals that are protective against paracetamol-induced liver injuries, thus, the plant was considered safe for use as ethnomedicinal remedies for liver disease in traditional medicine.
背景和目的:山茶(Camellia sinensis)是一种俗称绿茶的树种,具有很强的抗氧化性,可用于治疗癌症等疾病。本研究旨在评估植物化学物质,并评价茶叶提取物对 Wistar 大鼠肝脏的保护活性。方法:采用标准方法对植物化学成分进行筛选,并在扑热息痛诱导的肝脏毒性试验中,以 5 只大鼠或 6 只大鼠为一组,随机进行急性毒性研究和肝脏保护活性评估。结果:叶提取物的植物化学筛选显示了主要代谢物的存在。气相色谱-质谱分析显示有 18 种生物活性化合物,主要是脂肪酸,保留时间在 7.436 至 18.462 分钟之间。总酚含量(TPC)为 1425.22 毫克 GAE/克,总黄酮含量(TFC)为 802.01 毫克 QE/克。当提取物的剂量为 5,000 毫克/千克时,急性毒性没有产生任何毒性迹象。萃取物对肝脏具有剂量依赖性。与标准药物水飞蓟素相比,这些保护作用具有统计学意义(p<0.05)。以 200 和 400 毫克/千克体重的提取物剂量治疗八周后,所有动物组的肝功能生物标志物值均未升高,肝脏也未出现组织病理学损伤。结论:总之,研究表明,C. sinensis 甲醇叶提取物含有重要的植物化学物质,对扑热息痛引起的肝损伤具有保护作用,因此,在传统医学中,将该植物用作治疗肝病的民族药方是安全的。
