Today, emerging technologies have great impact to our lives in different ways. Modern technologies have revolutionized the way people communicates and interact all over the world. It simplifies life in so many ways and every one defines technology in their own way. Others define technology as science applied to practical purposes. This study aimed to provide a secured system that will alter the manual way of paying bills at school canteen by means of using RFID cards that is mainly capable of prepaid loading and earning points from the total amount of purchased items. The advantage of this system will benefit the people who are enjoying the canteen services. A card is allocated to each user and can be reloaded with a certain amount. A user needs to pay cash to the canteen owner for reloading the RFID card. The Prepaid RFID card for canteen project has a keypad for reloading and this keypad will be accessible only to the canteen owner. Results showed that the developed system is highly functional, highly reliable, highly efficient and highly secured.

Through the introduction of a variety of innovative technological devices, the independent travel experience for people who are blind or have low vision can be exponentially enhanced. To address this dearth of information, an online survey was developed with the assistance of the National Federation of the Blind to assess specific issues in the healthcare and navigation spaces for the Blind Low Vision [BLV], which has not been adequately addressed in existing surveys. The Survey included fifty-five questions in total, which included topics such as navigating obstacles, indoor and outdoor injuries, and access to healthcare. The results of the [herein referred to as the Survey] results are detailed within this paper. Following the Survey, three moderator-facilitated telephonic Focus groups were held with NFB to further validate and drill down on the Survey details, which will be used to design, develop, and test prototype concepts for the BLV.

Bioenergy is a versatile energy system. A multitude of feedstock, technology pathways, and end products encompass biomass-energy conversion. Amongst the renewable energy options, bioenergy has the unique potential to deliver significant benefits to society and the environment. Considering its prominence in the overall energy mix, the bioenergy sector has not received the desired attention. Its impacts on economic, social, environmental and greener energy factors are numerous. Due to the informal and local nature of most of the feedstock and technology used for biofuel production, it is very challenging to gather, analyze and report accurate and updated information on bioenergy developments. Moreso, it is important to note that there is a lack of reliable and updated data on bioenergy globally and locally. This paper, therefore explored available information on different biomass sources; current statistics on global and national bioenergy demand and utilization, its benefits and challenges; technologies for improving bioenergy production and yield from biomass; current climate challenges, and emerging biotechnology techniques relevant for sustainable biofuel production to meet energy demand and climate challenge.

Background and objectives: The production and productivity of dry beans in Ethiopia is hindered by multiple challenges; among these were biotic, abiotic and socioeconomic factors. Thus, this review paper highlighted and discussed those factors that impose dry beans not to give reasonable grain yield and acceptable quality there by to identify and discuss the main challenges of common beans under the study area, and to document the information generated from the paper for future improvement of dry beans. Material and Methods: A number of peer reviewed papers were critically viewed and reanalyzed based on the current situation of legumes production. Based on the investigation and observations made the author distinguished and prioritized the major threats of beans production for the study area. Results: Via different sources, information generated. The author also identified and prioritized the agents that limit the production of dry beans under the area and means of managing the challenges separately or by integration them. Conclusion: Therefore, the author recommend and suggest that to cultivate our farmlands in sustainable way we have to follow and apply the cropping patterns and systems of rotation with legumes to achieve this we must made bridge between technology generated with producers.

Hydrogen is one of the best possibilities for storing renewable energy in the power generation industry, and ammonia and hydrogen can be utilized in gas turbines to increase the flexibility of the power system. In order to cut emissions in coal-fired power plants, ammonia could potentially be used. This paper seek to see the usefulness, advantages, disadvantages, and classification of hydrogen fuel technology in renewable energy and to find various measures that could be taken in order to sustain the usage of hydrogen fuel in the subject.
