In order to accurately evaluate the emission situation of urban road network, this paper takes Zibo city as the research object, obtains the second-by-second emission data reflecting the actual road characteristics and vehicle characteristics through vehicle emission experiments, and establishes a motor vehicle emission measurement model coupled with the real-time road conditions using the vehicle experimental data. It is verified that the error of pollutant emissions calculated by the model is less than 10% of the actual measured value, and the accuracy of the model is good, which can be applied to the measurement of motor vehicle emissions in Zibo city road network and provide data support for the subsequent formulation of emission reduction measures.

The main objective of our study was to convey the importance of water to mankind. We can survive without food for several weeks, because our body will gradually switch to using stored fat and protein to make its energy, but cutoff of water supply leads to death of mankind within few days. Around two third of our body is water. On average we need 2.4 liters of water on each day to keep us healthy that’s the only reason people spend so much of money on water filters that will remove harmful impurities .in the early ages before the existence of filters, tubehole water was one of the sources of drinking water in our taluk. But according to the analysis in the recent years we found that this tubehole water had contamination of fluoride (2). In the later years many research scholars took initiative for the removal of fluoride in the tubehole water. This initiated us to make a comparative study to assess the quality of both filter and tubehole water found in the region of Pavagada. Unfortunately through our research we found that some of the water samples were unfit for drinking. Water samples of few areas were selected for qualitative analysis of water. Water samples were analyzed forexamination ofpH, Alkalinity, Acidity,Conductivity, Total dissolved solids (TDS), Total hardness, Calcium, Chlorine, Magnesium, Nitrate, Fluoride and Sulphate. It is important to monitor the physical properties of both filter and tubehole water, as it is a early warning signal that something is happening to water.

The need for alternative renewable energy resources have variegated science in the 20th century due to economic and environmental security concerns of the society brought by increasing fuel demands with respect to global population growth. This research has investigated the potential second generation ethanol feedstock of invasive perennial weed species of Astera plant family which have been polluting local grazing land areas for a long time. Using gas chromatograph – mass spectrometer, dilute acid and alkaline extraction pretreatment methods along with simultaneous saccharification and fermentation using commercially available enzymes have found out to produce significant amounts of converted bioethanol ranging from 1.969% to 12.217% yield per dried weight of biomass used. The research has also confirmed the significant difference in the bioethanol yield between non-pretreated and pretreated lignocellulosic biomass with one-way ANOVA and post hoc analysis. Hence, it is highly recommended to venture the potential of sustainable perennial plant species as feedstock biomass and determine optimization mechanism for alternative efficient pretreatments for sustainable and efficient ways of alternative bioethanol production.

In this study an attempt has been made to understand the hydrological process of kogi river Niger-benue basin by drawing inferences from morphometric analysis. The aim of the study is to assess the effectiveness of Remote Sensing and Geographic information systems (GIS) in the mapping and morphological analysis of the basin in question. River basin delineation, maping of slope, aspect, flow direction, flow accumulation, and Stream ordering have been accomplished using Hydrology tool in ArcGIS 10.2. Software. Strahler's and Horton’s method of stream ordering have been used for all stream related calculations. Drainage characteristic such as stream length, mean stream length, stream length ratio, Bifurcation Ratio, Basin length, Basin’s perimeter, Form factor, Drainage density ,circulatory ratio and stream frequency have been calculate . The river basin is designated as 4th order basin, with 1st order streams dominating. Strahler’s method of stream ordering adopted, revealed that the basins have seven (7) four order streams, twenty two (22) third order streams, thirty eight (38)second order streams and eighty six(86) first order streams. This study further recorded a drainage density of 0.089612 km-2, stream frequency of 0.005391 km-2, and circulatory ratio of 0.298 with a value of 0.247 for the form factor. These inferences shows that the basin is drainage coarse textured, low stream frequency, fairly elongated in shape and low discharge potential.

The overall objective of this work was to assess the effectiveness of Income Generating Activity (IGA) in the maintenance of school and health infrastructure built by the Congolese Institute for Nature Conservation in favour of the population living near the National Park of the Maiko / Southern Sector. At the end of our research, while relying above all on the effectiveness of IGAs in the maintenance of school and health infrastructure, we came to find the results according to which: 65.3% of our respondents showed that the Activities Income generators chosen were not effective in the maintenance of infrastructure following a plague which had devastated almost three quarters of goats and also the lack of mastery of the method of cultivation of corn and rice which made a constraint to the realization of these activities. In view of the difficulties encountered in the implementation of IGAs, the respondents expressed their preferences as part of a reorientation of the choices in relation to the specificities of the environment. To this end, 44.1% of our respondents prefer fish farming while 11.7% still encourage the rearing of small livestock, then 23.5% of our respondents planned the rearing of large livestock and in order to 20, 5% opted for the pharmacy.

Herbal medicines are getting more importance in the treatment of various diseases like diabetes, cancer and hepatic disorder. Diabetes mellitus still is the serious medical problem to human health due to rapid increase and cause of death in the developed and developing countries. It characterizes by hyperglycemia because there is the defect in insulin secretion, or the reduced sensitivity of the tissue to insulin formation. Apart from currently available therapeutic options, many herbal medicines have been recommended for the treatment of diabetes. The newer anti-hyperglycemic drugs continue searching because the existing synthetic drugs have several limitations. Herbal drugs are prescribed widely because of their effectiveness, less side effects and relatively low cost. Abroma augustam Linn is one of such ayurvedic remedy (medicinal plant) that has mentioned in many Bangladesh and Indian medicinal literatures. Abroma augustam contains several kinds of glycosides, flavonoids, Gallic acid and phenolic compounds in varies plant parts extract. Researchers have shown the scientific support for the use of Abroma augustam roots, bark and leaves extract in the traditional system of medicine for the treatment of diabetes mellitus. However, there are no data available about the hypoglycemic activity of green fruits and mature flower of A. augustam. Therefore, the current study aims to investigate the antidiabetic potential of A. augustam green fruits and mature flowers extract for preparing new treatment of diabetes mellitus with the formulation of novel drugs.

The overall objective of this study was to analyze the practice of ichthyotoxic plants and its impacts on aquatic biodiversity in the buffer zone of Lomami National Park.To do this, the methodological approach was based on the MARP (Accelerated Method of Participatory Research), insofar as it takes into account the active participation and the free expression of the points of view and the practices of the members of the communities. Targeted. It emerges from this study that the ichthyotoxic plants most exploited in the different biotopes of the study sites provided 8 species including Pachyelasma tessmannii, Bligia welwitschii, Tephrosia vogellii, Drypetes gossweileri, Adhadota bolomboensis, Derris elliptica, Tetraptera tetrapleura and others.In the years 1980-1990, we could collect up to 5 tonnes of fish but the sudden drop was observed in the years 1997-2000, despite the increase in the quantity of fish during the years 2001-2004 following the war only to cross the Democratic Republic of Congo, causing an abandonment of rivers by the fleeing community, in 2020 the quantity fished would be less than 1 ton.Currently, fishing is done two or three times a year with an estimated annual income of between $ 250 to $ 400 according to the response of 65% of our respondents. In addition, 25% of respondents revealed to us that this activity can provide up to $ 450 to $ 500 per year and finally, 5% confirmed that income can go beyond $ 500 due to a monthly income ranging from $ 20 to $ 40. In view of this, it is obvious to relaunch productive alternative activities to fishing against the use of ichthyotoxic products, and finally to increase the socio-economic income of the riparian population and ensure the sustainable management of aquatic ecosystems.

La présente étude avait pour objectif global d’analyser la pratique des plantes ichtyotoxiques et ses impacts sur la biodiversité aquatique dans la zone tampon du Parc National de la Lomami. Pour ce faire, L’approche méthodologique s’est basée d’une part sur la MARP (Méthode Accélérée de Recherche Participative), dans la mesure où elle prend en compte la participation active et l’expression libre des points de vue et les pratiques des membres des communautés ciblées.Il ressort de cette étude que les plantes ichtyotoxiques les plus exploités dans les différents biotopes des sites d’étude a fourni 8 espèces dont Pachyelasma tessmannii, Bligia welwitschii, Tephrosia vogellii, Drypetes gossweileri, Adhadota bolomboensis, Derris elliptica, Tetraptera tetrapleura et autres.Dans les années 1980-1990, on pouvait ramasser jusqu’à 5 tonnes de poissons mais la chute brutale s’est observée dans les années 1997-2000, malgré l’augmentation de quantité de poissons au cours des années 2001-2004 suite à la guerre qu’à traverser la République Démocratique du Congo, causant un abandon de rivières par la communauté en fuite, en 2020 la quantité pêchée est inférieure à 1 tonne.Actuellement, la pêche s’effectue deux ou trois fois par an avec un revenu annuel estimé entre 250 à 400 $ selon la réponse de 65% de nos répondants. En outre, 25% des enquêtés nous ont révélé que cette activité peut procurer jusqu’à 450 à 500 $ par an et enfin, 5% ont confirmé que le revenu peut aller au-delà de 500$ en raison d’un revenu mensuel allant de 20 à 40$.Aux vues de cela, il est évident de relancer les activités alternatives productives à la pêche contre l'usage des produits ichtyotoxiques enfin d’accroitre le revenu socio-économique de la population riveraine et d’assurer la gestion durable des écosystèmes aquatiques.

This study was carried out in the town of Kindu from December 2020 to February 2021 and had the overall objective of determining the perception of climate change, the environmental impacts and the endogenous adaptation strategies implemented by the farmers of Misenge to deal with this phenomenon. To achieve this, the data collection techniques used were mainly based on sociological surveys carried out with 123 farmers in Misenge and the percentage chosen as a comparison index of the significance level of the data. It therefore emerged that the agriculture practiced in Misenge is mainly rain-fed (100% of farmers); no farmer in Misenge has access to agricultural credit or is subsidized, only 14% of farmers in Misenge admitted to having received training on different agricultural technologies at least once. The decrease and irregularity of the rains, the late start of the rainy season, the early stopping of the rains, the higher frequency of dry sequences, the occurrence of violent winds and eddies, dust mists; hotter days, increasingly hotter nights, shortened cold periods, appearance and extension of barren soils, gravelly soils, appearance and spread of crop diseases and pests, decrease in herbaceous plants, drying out and death of trees are all facts observed by the inhabitants of Misenge which may be attributable to climate change. So to face these climate changes, the farmers of Misenge implement and use several strategies: Appeal to the gods (54%), Cultural nomadism (89%), use of seeds of improved varieties (12%), adjustment of the agricultural calendar. compared to sowing periods (85%), the use of chemical fertilizers to increase yields (2%).

Hyperspectral remote sensing is one of the advanced technologies which began in early 1980s and is one of the most significant breakthroughs in remote sensing. Image acquisition, feature extraction and classification play a vital role during the classification of hyperspectral remote sensing images. AVIRIS could be a refined and complicated optical sensor system involving variety of major subsystems, components and characteristics. Therefore Image Acquisition is done using AVIRIS sensors. The selection of appropriate remotely detected information needs considering factors like the needs of the end user, the scale and characteristics of the study area, available image data and their characteristics, cost and time constraints, and the analyst’s experience in using the selected images. Nonparametric Weighted Fuzzy Feature Extraction method is used here which merges the Nonparametric Weighted Feature Extraction and Nonparametric Fuzzy Feature Extraction. Classification could be a difficult however necessary task for hyperspectral remote sensing applications, as well as land use analysis, pollution observance, wide-area intelligence activity, and field surveillance. A multiple classifier system is a powerful solution to classify the Hyperspectral Remote Sensing Images. The Minimum Spanning Forest approach is well suitable for spectrally confusing classes. Markov Random Field classifier is well suitable for spatial information. Hence this work employs spectral classification using Minimum Spanning Forest classifier and spatial classification using Markov Random Field classifier and combines the results of MSF and MRF using decision fusion.

The SARS-CoV-2 virus, the causative agent of COVID-19, has become a formidable enemy to mankind for its ability to quickly mutate & evade the immune system of the host. We have reported earlier that the territory of Lakshadweep in India reported the first case of COVID-19 in January, 2021 long after its invasion in the other states of the country. And following its first appearance, there was gradual spread of the disease in the population which was waning by the end of March, 2021. The waning of COVID-19 was attributed to prior immunization of the population with MMR (Mumps Measles Rubella) vaccine. In this article we have continued the study until July 31, 2021 and a significant observation was that after a pause in the number of COVID-19 cases, there was an increase in number of confirmed & active cases of COVID-19. However, an abrupt fall in the number of active cases of COVID-19 followed and by six months there were insignificant number of active cases of COVID-19. Significance of these observations has been discussed in this article.
