Wimax Network

Every new technology comes with its challenges and lessons to be learnt. With a number of unknowns, deploying a new technology becomes a challenge. Worldwide Interoperability for Microwave Access (WiMAX) is one of these new technologies currently on the rise. This paper presents the finding of the research conducted to investigate technical and non technical aspects of network operators in Tanzania. The research looked into WiMAX network operational challenges faced by the network owners as well as the level of services experienced by the end users. This paper is suitable researchers, network operators and investors interested in WiMAX technology. It is mostly usefully for those looking into solutions to problem facing rural and remote areas of the world. The research is discussed in detail throughout of the article.

 The constitution of Nepal (2015), article 35 (Right relating to health) stated that every citizen shall have the right to free basic health services from the State, and no one shall be deprived of emergency health services. According to the World Bank report (collection of development indicators compiled from various official sources, 2016), Nepal has 81% rural and remote populations. Health service delivery is a complex reality for the rural and remote populations and faces enormous challenges. One of them is insufficient and uneven distribution of health workforce. The World Health Report concluded that "the severity of the health workforce crisis is in some of the world's poorest countries, of which 6 are in South East Asia out of 57 countries having critical shortages of health workforce."1Even after 13 years situation has not much improved. Nepal faces a critical shortage of trained health workforce, especially in rural and remote areas. Health workforce recruitment and retention in rural and remote areas is a difficult task challenged by the preferences and migration of health workforce to urban areas in country, or even abroad for better life and professional development.2 One of the most effective strategies for health workforce recruitment and retention for rural and remote areas could be that of establishing and maintaining Medical Education in rural and remote areas decentralized from urban academic medical centers.

Abstract Background Studies in South Africa showed that cataract was the second leading cause of blindness and the leading single cause of severe visual impairment. People living in the rural and remote areas of the world are usually of lower socio-economic status and therefore lack the opportunity to utilize eye care services adequately which could result to lack of knowledge regarding cataract surgery. The primary aim of the current study was to increase a better understanding of eye health inequalities in Limpopo province with specific reference to cataract surgery and care. The study sought to answer a central question “What are the barriers related to the uptake of cataract surgery and care in Limpopo. Methods This study used qualitative and descriptive designs through exploring barriers related to the uptake of cataract surgery and care from professional nurses’ perspective. The target population comprised of 20 ophthalmic supportive staff. A non-probability, purposive sampling was applied to select three hospitals in which cataract surgeries are performed. All the 20 ophthalmic supportive staff purposively comprised the sample of the study. Data were collected through Focus Group Discussions. The Tesch’s principles as a guide for classifying data into themes and sub-themes applied. Ethical consideration and trustworthiness for data quality were explained. Results The study found that patient ignorance, low education and illiteracy, lack of awareness programmes, shortage of ophthalmologist and supportive ophthalmic health professionals, inadequate cataract facilities and resources lead to poor quality services in the hospitals were the major barriers in the uptake of cataract surgery and care. Conclusion People living in the rural and remote areas of the world are usually of lower socio-economic status and therefore lack the opportunity to utilize eye care services adequately. There is need to expand the awareness programmes and health education regarding prevention of the risks of blindness among the elderly in particular.

The way of generating and distributing energy throughout the electrical grid to all users is evolving. The concept of Smart Grid (SG) took place to enhance the management of the electrical grid infrastructure and its functionalities from the traditional system to an improved one. To measure the energy consumption of the users is one of these functionalities that, in some countries, has already evolved from a periodical manual consumption reading to a more frequent and automatic one, leading to the concept of Smart Metering (SM). Technology improvement could be applied to the SM systems to allow, on one hand, a more efficient way to collect the energy consumption data of each user, and, on the other hand, a better distribution of the available energy through the infrastructure. Widespread communication solutions based on existing telecommunication infrastructures instead of using ad-hoc ones can be exploited for this purpose. In this paper, we recall the basic elements and the evolution of the SM network architecture focusing on how it could further improve in the near future. We report the main technologies and protocols which can be exploited for the data exchange throughout the infrastructure and the pros and cons of each solution. Finally, we propose an innovative solution as a possible evolution of the SM system. This solution is based on a set of Internet of Things (IoT) communication technologies called Low Power Wide Area Network (LPWAN) which could be employed to improve the performance of the currently used technologies and provide additional functionalities. We also propose the employment of Unmanned Aerial Vehicles (UAVs) to periodically collect energy consumption data, with evident advantages especially if employed in rural and remote areas. We show some preliminary performance results which allow assessing the feasibility of the proposed approach.

Cleaning Methods

Abstract Traditional grain cleaning methods are labor-intensive, time-consuming, and yet very inefficient. The use of available mechanical seed cleaners is widely limited since they are expensive to own, operate, and maintain. A Pedal Operated Seed Cleaner (PoS-Cleaner) was developed and its performance evaluated. Appropriate engineering principles and methodologies were used in the sizing and construction of the machine. The cleaner consists of a bicycle-like pedaling system, hopper, a centrifugal fan, and three cleaning sieves which include two inside interlocking sieves (one sieve fixed and the other adjustable); whose meshes can be adjusted to be larger than the size of the unclean seeds by longitudinally translating the second sieve to achieve the appropriate seed size. This allows trapping of impurities larger than the seeds. Cleaning rates of 576.5 kg/h, 375.8 kg/h, and 377.4 kg/h for maize, beans, and groundnuts were obtained respectively. Maize, beans, and groundnuts had their highest cleaning efficiencies of 95.09%, 87.61%, and 81.67% at inner sieve sizes of 13 mm, 16 mm and 10 mm respectively, pedaling speed of 60 rpm. The PoS-Cleaner presents a more viable cleaning option for smallholder farmers in rural and remote areas with no access to the national grid, therefore producing high-quality seeds. This will eventually facilitate agricultural value addition and increase individual family incomes in Uganda. Article highlights A pedal operated multi-seed cleaner was developed. Achieved 5 times higher seed cleaning rates compared to traditional cleaning technologies. Attained higher separation efficiencies of seed and externalities compared to traditional technologies.
