Managing Editor June 10, 2021Science and Technologybio-indicator, heavy metal, Neem bark, township and pollution Leave a comment

In this study, the bark of the neem tree (Azadirachta indica) is used as a bio-indicator to monitor heavy metal pollution in Katsina township. Heavy metals can be absorbed by plants through their roots from the soil and water, as well as through their leaves from the atmosphere. Heavy metal uptake, accumulation, and translocation Metal concentrations in plants may differ between species due to anatomical and physiological differences. Yells are taken from four different locations in Katsina township, including; Katsina … Continue reading “Bark of Neem Tree (Azadirachta indica) as Bioindicator for Deposition of Heavy Metals around Katsina Steel Rolling Company in Katsina Township”

Assessment of Trace Metals in the Leaves of Adansonia digitata and Eucalyptus globulus along Dutsinma Road in Batagarawa Local Government Area of Katsina State

Using atomic absorption spectrophotometry, the burdens of seven trace metals, Mn, Zn, Pb, Cr, Co, Ni, Cu, and Fe, were studied in the leaves of two tree plant species in the region of Batagarawa Local Government Area in Katsina State. The tree plants were Adansonia digitata (Baobab) and Eucalyptus globulus (Gum tree). The results showed the levels of metals (µgg-1 per dry weight) in baobab leaves to be 46.00 (Mn), 23.50 (Zn), 2.00 (Pb), 12.50 (Cr), 12.00 (Co), 2.00 (Ni), … Continue reading “Assessment of Trace Metals in the Leaves of Adansonia digitata and Eucalyptus globulus along Dutsinma Road in Batagarawa Local Government Area of Katsina State”

New Bottle for Milk: An Approach towards Positive and Negative Aspects

Managing Editor June 3, 2021Science and TechnologyBottle, cream, empty space, problem, shape Leave a comment

This paper will describe a novel approach to overcoming the aforementioned obstacles. We’re all familiar with the typical bottle and carboy shapes. They have a two-part form that is cylindrical (below) and conical (above) in most cases [1-3]. And we’d become used to it. Evidently, this is a really simple method of consuming beverages (water, milk, cream, mayonnaise, beer, juice, oil, kefir and so on). I’m not interested in having a discussion about it. However, in practice, everything has both … Continue reading “New Bottle for Milk: An Approach towards Positive and Negative Aspects”

Advertising Design in Vietnam’ Character: Variation of Visual Design Elements in Outdoor Advertising

Visual design elements have received special attention, and have even become a trend, spreading throughout the art of design, particularly in outdoor advertising. In the era of Vietnam’s international integration, there have been a lot of changes in advertising posters, and visual design aspects play a big part in it. Advertising posters are combined with visual languages, resulting in a completely new aesthetic experience. From 2017 till now, the research examines how Visual Art components have been presented in outdoor … Continue reading “Advertising Design in Vietnam’ Character: Variation of Visual Design Elements in Outdoor Advertising”

Recent Survey on Voice to Text Conversion

Managing Editor June 3, 2021Science and Technologyspeaker, Speech translation, steps for speech recognition and classification Leave a comment

We can see a recording system that translates voice to text and then searches for it in today’s current search engines, such as Google. This is an example of a data retrieval system. Speech is a vital component of human life since it allows two or more people to communicate. Speech to text conversion is required because certain persons are unable to talk openly with others, and it facilitates communication. Deaf people can use speech to text translation. people to … Continue reading “Recent Survey on Voice to Text Conversion”

Investigating of the Aba River Contamination Using Eichhornia crassipes as Bio-indicator

Managing Editor June 3, 2021Science and Technologybio-indicator, Contamination, Eichhornia crassipes, pollution index, river Leave a comment

Eichhornia crassipies were used to investigate the seasonal variation of heavy metal contamination levels in the Aba River in Abia State, Nigeria. The presence of Macrophytes in rivers is frequently a strong indicator of heavy metal accumulation in water bodies. To cover the Nigerian rainy season and the Harmattan season, bi-monthly sampling was carried out. At the UST, PZA, ABT, and DST sampling points, iron (Fe) was more abundant, with a maximum concentration of 69.5 mg/kg in December/January. The lowest … Continue reading “Investigating of the Aba River Contamination Using Eichhornia crassipes as Bio-indicator”

Study on UWB-Based Low-Cost and Precise Localization Method for Mobile Robots

Managing Editor June 3, 2021Science and Technologyautomating cargo management, manufacture environment, mobile robots, Precise localization method Leave a comment

Mobile robots can be used to transport freight, and this form of robot is referred to as an automated guided vehicle. In a manufacturing context, cargo management automation is critical. It is now possible because to recent advances in the fields of big data and artificial intelligence. Most cargoes are transported utilizing autonomously guided vehicles or labor, as we all know. Many autonomously guided vehicles go along pre-determined pathways that are usually marked with labels that are easily visible to … Continue reading “Study on UWB-Based Low-Cost and Precise Localization Method for Mobile Robots”

Studies of Functional Modeling in the IDEF0 Standard as the Initial Stage of TPPs Design

Managing Editor June 3, 2021Science and Technologyfunctional modeling, IDEF0 standard, TPPs design Leave a comment

The design and operation of thermal power plants (TPPs) in the Russian Federation are governed by a collection of regulatory and technical documents. During the initial design stage, it is critical to coordinate legal, environmental, and other TPP indicators with specialists from many profiles, as well as define a broad concept and structure for the station. In the Russian Federation’s traditional professional requirements, there are no documents that regulate this procedure. A set of IDEFs and a methodology At the … Continue reading “Studies of Functional Modeling in the IDEF0 Standard as the Initial Stage of TPPs Design”

Investigating the Impacts of Ambient Air Quality of an Industrial Region on a Member of Asteraceae and Its Potentials as a Phytomonitor

Managing Editor June 3, 2021Science and TechnologyAir pollution, parameters, phytomonitoring, tithonia Leave a comment

Tarapur, a densely populated and heavily industrialized city, provides ideal settings for studying the impacts of urban stress on plants. Because plants’ foliar surfaces are major pollution receptors, choosing appropriate plant species for urban environments is critical. During the 2011 dry season, Tithonia diversifolia, a member of the Asteraceae family, was exposed to five distinct sites. For thirty days, the transplants were exposed. The dry weight of the phytomass, the length of the shoots, the total chlorophyll content, and the … Continue reading “Investigating the Impacts of Ambient Air Quality of an Industrial Region on a Member of Asteraceae and Its Potentials as a Phytomonitor”
