Among various environmental pollutants, dyes have been reported to contaminate a large quantity of surface water. Rhodamine B, a widely applicable basic dye is known for its hazardous impact on environment. The present work proposes the production, characterization of activated carbon and its application for the removal of Rhodamine B from aqueous medium. The activated carbon was prepared from Sechium edule commonly known as chayote by chemical activation using nitric acid (HNO3) as an activating agent. The prepared activated carbon was used for the characterization of matter soluble in water, matter soluble in acid, conductivity, pH, apparent density, iodine number, determination of zero-point charge, determination of surface functional groups by Boehm's titration and proximate analysis which includes moisture content, volatile matter content, ash content and fixed carbon followed by the application for the removal of rhodamine B by preparing Stock solution and testing the concentration with the help of UV-VIS spectrophotometer.

Keywords: Pollutants, basic dyes, activated carbon.

A fuzzy Inference System toolbox developed with MATLAB is used in this paper to analyze the performance of a heat exchanger. Firstly, an analysis of a heat exchanger is conducted using a model which represents the heat exchanger based on a process reaction curve obtained from a pilot plant. Secondly, this research then compares the control performance of PID (Proportional Integral and Derivative) and fuzzy logic controllers. A comparison of PID (Proportional Integral and Derivative) and fuzzy logic controllers are then conducted. These control performances are used to draw conclusions. In the end, fuzzy controllers perform similarly to PID controllers in terms of control performance but give a better response when compared to PID controllers..

KEYWORDS: Heat exchanger, Fuzzy logic controller, Proportional Integral and Derivative Control.

Food is an important tourism product for differentiating a group of people from another. It defines a people's identity and can be used as an instrument of prestige at an international level. People eat out not because they starve, but because they are psychologically looking for the self-identity leisure motive. This paper highlights the nutritious and delicious dishes of Imo State of Nigeria. These dishes include the ofe Owerri, ofe ugbogiri/anyu, ofe ugba/okro, ofe okoroko, ngwobi, ugba agwugwo and isi ewu pepper soup. The paper is a review work, accomplished through secondary data collection. It also proposes a model of local food consumption that will attract food tourists to Imo State........

In recent years, under the high attention of the country, the ideological and political education in colleges and universities has achieved remarkable results, but the teachers, the relationship between the subject and object of education and the penetration of multiple values and other problems still seriously affect the effectiveness of mainstream ideological education. This paper analyzes the existing problems and reasons in the mainstream ideology education of college students, and explores new ideas from three aspects: strengthening the construction of counselors, reforming education methods and cultivating students' information literacy ability, so as to find practical ways to help college students resist decadent culture and wrong thoughts and strengthen the mainstream ideology.

The yield ranged from 12.9 percent to 62.7 percent for ethanol and ethyl acetate extracts for four types of citrus peels (Mandarin, Aurantim, blood orange, and navel orange), with ethanol extracts yielding the highest yield of ethyl acetate. Naval peels yielded the maximum amount of extract, according to the results (62.7 percent). Moisture, ash, carotenoids, chlorophylls, proline, and sugar were discovered to be characteristics of orange peel. Different proportions were found in all cultivars of the peel, according to the findings. A single noticeable peak at 320nm was discovered in an ultraviolet-visible spectrophotometric scan of the extract.

Customer engagement is an emerging construct in the marketing literature with preliminary research indicating that it has an important construct that not only reflects the results of customers' interactive experience and the specific brand but also enhances a firm's financial value. Contemporaneously, regarding interactive, business environments, engagement represents a wise strategy with the aim of boosting business performance including sales revenue, outstanding competitive advantage, and profitability. Therefore, the discovery of the importance of customer satisfaction was carried out in the ZaloPay service context. We found that service quality factor has the most influence on customer engagement, followed by customer perceived value and customer trust. Concurring with this observation, we suggest that specific customer engagement relational outcomes may expand to activate as its antecedents in ensuring customer engagement procedures and/or cycles over time. These findings, therefore, help ZaloPay in Da Nang improve to serve customers better and make ZaloPay have better marketing or service strategies in the future.

Litter is the most crucial component in forest ecosystems and plays a vital role to carbon sequestration. The present study was conducted on litter in the Kaptai national park under Rangamati Hill Tracts district at South Forest Division of Bangladesh. The main objectives of the study were to estimate biomass and carbon of litter in six forest areas of the Kaptai national park. The total number of plots was three hundred eight, where 100 m was apart from each other and each plot size was 1 m radius. Plots were selected using global positioning systems. A systematic sampling and destructive method were used for the estimation of litter carbon. Total litter samples were collected from each plot and carbon stock was converted per hectare. The maximum biomass was 1.5 t ha-1 in Gmelina arborea and the minimum biomass........

Soil is the important and the largest carbon pools in the terrestrial forest ecosystems. Soil is a major source of organic carbon in a forest. Soil contains 4-5 times more organic carbon than all living things three to fourfold greater than plantation. The present study was conducted to estimate the soil organic carbon in the Kaptai National Park, Kaptai, Rangamati Hill Tracts district, Bangladesh. A systematic method was used to identify each sampling point through the Global Positioning System. The study was explored soil pH, soil organic carbon, bulk density and soil organic matter. Soil samples were collected from 0-15, 15-30, 30-45, 45-60, 60-75 and 75-90 cm depth for the estimation of the above parameters. Soil organic carbon (SOC) was determined by Walkley-Black method. Bulk density was calculated.......

The materials that generate the greatest amount of waste worldwide are plastics, which cause negative effects on the environment because plastic is a polymer derived from petroleum. Plastics are non-renewable elements with high durability and no self-decomposition. For this reason, recycling is a strategy fundamental to the reuse of plastic waste. Currently, approximately one-third of urban solid waste in the main cities of Colombia is plastic. These have exponential growth every year. The purpose of this project is to realize an analysis of a virtual model for the classification and use of plastic waste with the data of a polypropylene recycling company, where the points or operational phases to determine.......
