Air pollution is one of the main risk factors for human health. It is the deadliest form of environmental pollution, which the World Health Organization has recognized as a significant indicator of the status of the environment. Therefore, there is a need for monitoring of air pollution to reduce health hazards associated with it. In this study, Remote Sensing and Geographic Information System were used to examine the spatiotemporal distribution of air pollutants in Ogui New Layout, South-East, Nigeria so as to advise the populace and relevant agencies on the steps and needs in reducing air pollution. Based on dense industrial clusters, heavy traffic and increasing human population density, strategic places were sampled between two peak hours (8 am and 4 pm). A Haze-dust particulate monitor and a Gasman Air Monitor were used to measure the amounts of PM10, CO, SO2, and NO2. The global positioning system (GPS) coordinates of the sampling spots were recorded using the portable Germin-300 GPS device analyzer which was also used in data processing for creating spatial interpolation maps in ArcMap. ArcGIS 10.5 Erdas Imaging 9.5 software was used to analyze the spatial distribution of contaminants from a source using remote sensing and geographic information system (GIS) methods. Results showed that during the dry season, the air pollutants (PM10, CO, SO2, and NO2) had maximum values of 225, 10.72, 1.74, 1.93 respectively and minimum values of 184, 8.86, 0.82, and 0.45 respectively. During the wet season, PM10, CO, SO2 and NO2 had maximum values of 202, 16.66, 1.65, 0.73 respectively and minimum values of 108, 11.85, 0.69 and 0.26 respectively. Based on the study, it is advised that the local people of Ogui New Layout reduce their exposure to the outdoors especially during the dry season.

The present investigations were focused on the systematic analysis of surface water quality of the Thamirabarani River from upstream (Pechiparai dam to Gnaramvilai) to downstream (Vettuvenni to Thengaipattinam estuary) during the period from September 2020 to January 2021. The different hydrochemical parameters such as temperature, pH, EC, TDS, fluoride, turbidity, nitrate, phosphate, sulphate, chloride, calcium, magnesium, total hardness, DO, BOD, bicarbonate, carbonate, sodium and potassium were determined upstream (S1-S5) and downstream (S6-S10) of the river water samples. The results showed that the weighted Arithmetic Water Quality Index (WAWQI) values designated two sampling stations out of ten sampling stations ‘Good’ category and another eight sampling stations ‘poor - unsuitable’ category. The results obtained were subjected to multivariate statistical analysis using Correlation matrix the significant relationship among the parameters (significance level with 0.01 and 0.05) PCA and Cluster was also calculated to determine the high pollution loads in the water sample. The mean values of the respective major ions determined are represented in the Schoeller- Berkaloff diagram. From this study the water quality was severely polluted both upstream and downstream region the water quality index and multivariate techniques can be employed for monitoring river resources which can help inadequate planning and management of the Thamirabarani river system. Key words: Correlation analysis, cluster analysis, hydrochemical parameters, principal component analysis, statistical analysis, water quality index.

Cell phones and mobile devices have been an integral part of life over the past 30 years. In parallel with the intensity of use of mobile phones, the number of base stations has also increased. The increasing number of base stations has caused an intensity of electromagnetic pollution in the GSM band. The issue of electromagnetic pollution has become increasingly remarkable due to the claims that it can cause diseases and scientific studies carried out in this field. The number and variety of studies carried out in the last 30 years in this regard has also increased. Base stations are established with various features. While some kinds of base stations use radial antenna type, some of them use directional antennas. Depending on the region where it is established, the cell types it uses may also differ. Therefore, multiple measurements are required to analyse the impact of a base station. However, it is practically not possible to make an infinite number of measurements. Within the scope of this study, it is aimed to refine and clarify the electromagnetic pollution maps by using artificial intelligence methods. As a result of the studies carried out in this area, electromagnetic pollution maps have become much more detailed.

An experiment to determine the effect of poultry manure (PM) application rates on growth and yield of S. senegalensis was conducted at the Department of Crop Science, University of Nigeria, Nsukka. The experiment was a Randomized Complete Block Design (RCBD) of four rates of poultry manure (0, 10, 20 and 30 t ha–1) replicated three times. Analysis of variance results indicated that PM significantly (p < 0.05) influenced most of the growth attributes measured with 20 t ha-1 having the longest vine (106.5 and 140.3 cm) at 4 and 5 MAT, respectively. It also produced more leaves (77.9, 132.1, 175.9 and 250) at 2, 3, 4 and 5 MAT, respectively and had the highest number of branches of 13.85, 22.70, 27.6, 39.2 and 61.1 across the months. Most of the phenological traits were positively influenced by PM rates. Earliest days to 60% (138.0 days) and 100% (167.0 days) flower bud formation, flower bud break (191.0 days) and fruit formation (194.3 days) were associated with 30 t ha–1 of PM. Poultry manure had no significant effect on all the yield components and yield measured. Although, PM applied at 20 t ha–1 had the earliest days (706) to harvest and had the tendency to increase S. senegalensis yield. Further increase of PM rate beyond 20 t ha–1 decreased growth and yield traits taken. The use of PM at 20 t ha–1 appeared optimum and could be recommended for the cultivation of S, senegalensis in the study area.
在尼日利亚大学恩苏卡分校作物科学系进行了禽粪施用量对塞内加尔稻生长和产量影响的试验。试验采用随机完全区组设计(RCBD)， 4种添加量(0、10、20和30 t hm - 1)重复3次。方差分析结果表明，PM显著(p < 0.05)影响了20 t hm -1条件下的大部分生长属性，在4 MAT和5 MAT条件下，葡萄蔓最长(106.5 cm和140.3 cm)。在2、3、4和5 MAT时叶片数量分别为77.9、132.1、175.9和250片，分枝数最高，分别为13.85、22.70、27.6、39.2和61.1。大部分物候性状均受PM率的正向影响。施用30 t ha-1 PM可使花蕾形成时间提前至60% (138.0 d)、100% (167.0 d)、花蕾破裂时间提前至191.0 d、果实形成时间提前至194.3 d。禽粪对产量各组成部分及实测产量均无显著影响。施用20 t hm - 1 PM收获时间最早(706年)，且有提高塞内加尔葡萄产量的趋势。超过20 t hm - 1后，进一步增加PM率会降低生长和产量性状。20 t hm - 1 PM的施用效果最佳，可推荐用于研究区塞内加尔沙芥的栽培。

The development of countries is now mostly dependent on their research and how fast they can convert the results into tangible products and services. Employment of research for industrial development is not being encouraged in developing countries. Developing countries must engage more in research that will contribute positively to their economy. Encouraging collaboration and entrepreneurship within and across different disciplines will serve as impetus to create alternative local products as well as chart a course for a competitive future. The transfer of innovative research and technology from our universities and research centers into the economy can be driven by university lecturers and researchers from institutes.

In recent years, Nattrassia mangiferae has received tremendous attention as a destructive plant pathogen that may potentially infect humans and animals. The pathogen was isolated from 61 species belonging to 47 genera and 30 family plants but was most frequently isolated from Cactaceae, Rosaceae, Euphorbiaceae, Anacardiaceae, and Rutaceae hosts. To systematically and comprehensively describe the progress, trends, and hotspots of N. mangiferae research, the 376 related publications from 1966 to 2022 were collected from the Scopus database. The bibliometric characteristics including publication output, countries/region of focus, author’s productivity, most prolific authors , authorship pattern, citation frequency, institutes, most prolific journ als, and research focus were evaluated by using Excel 2013 and VOSviewer. Out of 376 original articles, there are 139 plant and 237 human studies. The leading countries based on the number of publications were the United States, the United Kingdom, and Brazil. A sharp increase in the number of studies related to the pathogenicity of N. mangiferae during 2018 to 2021 was observed, coinciding with an increase in the number of short reports and outbreak reports worldwide. The journal and subject categories with the most significant publications are Plant Disease and Medical Mycology, respectively. The most common document types were article, note, review, and letter. N. mangiferae is a thermophilic fungus, and warming temperatures may weaken trees and affect their susceptibility to this pathogen. The increase in reports of the pathogenicity of this pathogen on various plants and humans from 70 different countries in recent years shows the importance of this pathogen as a sever threat to the world. Our bibliometric analysis reveals the current research hotspots and topic trends on N. mangiferae , thus offering potential clues for further examination.
