No full textOlalekan Akanji Bello*, Sani Ibrahim Doguwa, Abubakar Yahaya and Haruna Mohammed Jibril
Several new improved, generalized, and extended families of distributions have been discovered in recent years from families of distributions to aid their application in a variety of fields. The Type I half-logistic exponentiated-G family of distributions which generalizes and extends the Type I half-logistic family of distributions, with two extra positive shape parameters is investigated and proposed. We discuss some of the statistical properties of the proposed family such as explicit expressions for the quantile function, ordinary and incomplete moments, generating function, reliability, and order statistics. Some of the new family’s sub-models are discussed. We discuss the estimation of the model parameters by the method of maximum likelihood. Two real data sets are employed to show the applicability and flexibility of the new family
WEB-BASED HOSPITAL MANAGEMENT INFORMATION SYSTEM A CASE STUDY OF IBRAHIM BADAMASI BABANGIDA UNIVERSITY HEALTH CARE CENTRE, LAPAI, NIGER STATE
No full textHospitals are the essential part of our lives, providing best medical facilities to people suffering from various ailments, which may be due to change in climatic conditions, increased work-load, emotional trauma stress. It is necessary for the hospitals to keep track of its daily activities and records of its patients, doctors, nurses, and other staff personals that keep the hospital running smoothly and successfully. But keeping track of all the activities and their records on paper is very tedious and prone to error. Also, it is very inefficient and a time-consuming process Observing the continuous increase in population and number of people visiting the hospital. Recording and maintaining all these records is highly unreliable, inefficient and prone to error. It has also been observed that patient records tend to be duplicated and sometimes unavailable at critical time when it is required for emergencies. It is also not economically and technically feasible to maintain these records on paper, this paper proposed the use of Web-based Hospital Management Information System in automation of the Ibrahim Badamasi Babangida University Lapai Health care Centre
The role of big data in smart city
No full textThe expansion of big data and the evolution of Internet of Things (IoT) technologies have played an important role in the feasibility of smart city initiatives. Big data offer the potential for cities to obtain valuable insights from a large amount of data collected through various sources, and the IoT allows the integration of sensors, radio-frequency identification, and Bluetooth in the real-world environment using highly networked services. The combination of the IoT and big data is an unexplored research area that has brought new and interesting challenges for achieving the goal of future smart cities. These new challenges focus primarily on problems related to business and technology that enable cities to actualize the vision, principles, and requirements of the applications of smart cities by realizing the main smart environment characteristics. In this paper, we describe the existing communication technologies and smart-based applications used within the context of smart cities. The visions of big data analytics to support smart cities are discussed by focusing on how big data can fundamentally change urban populations at different levels. Moreover, a future business model that can manage big data for smart cities is proposed, and the business and technological research challenges are identified. This study can serve as a benchmark for researchers and industries for the future progress and development of smart cities in the context of big data
Assessment of Organochlorines Pesticides Residues in Water, Fish and Sediment Samples from Wurbo Lake, Bali, Taraba State, Nigeria
No full textOrganochlorines pesticides (OCPs) have been used worldwide, particularly in many African countries as in Nigeria for the control of pests. OCPs are characterized by their bioaccumulation in the environment, especially in the food chain, where they find their way into the human body. The research was aim to estimate the residual concentrations of different OCPs in water, fish and sediment from Kundi Lake to find out the extent of pesticide contamination and accumulation. The water sample was subjected to liquid-liquid extraction method while the fish and the sediment samples were subjected to soxhlet extraction. The extracts were later analysed for organochlorines pesticide residues using Gas-Chromatography coupled with mass spectrometer (GC-MS). The average length, average weight and condition factor of the studied fish species were measured. The Mormyrus rume had the highest average length of 17.12±0.05 cm, and average weight of 195.36±0.05 g follow by Clarias gariepinus which had the average length of 16.83±0.01 cm, and average weight of 189.43±0.03 g. Tilapia zilli was the least species of fish sample with a length of 12.75±0.03 cm and average weight of 102.21±0.02 g. Also, all the fish species sampled in this present study had condition factors>1. Based on the results obtained from all samples, it was found that the levels of organochlorine pesticides residues in water were generally below MRL as compared with FAO/WHO (0.5ppm). In fish samples, highest concentration of pesticide residues in Mormyrus rume follow by Clarias gariepinus, while the Tilapia zilli recorded low concentration of the pesticide residues. The Endosulfan II recorded high concentration of 4.68 ppm in Mormyrus rume follow by Endrin which recorded the concentration of 2.75 ppm, Aldrin 1.78 ppm and Atrazine 1.72 ppm all in Mormyrus rume. In Clarias gariepinus, Simazine 1.56 ppm follows by Endosulfan I 1.28 ppm while In Tilapia zilli, Endosulfan II 1.16 ppm follows by Atrazine 0.91 ppm and Beta Lindane 0.81 ppm. The results indicate that the area is contaminated with high levels of these pesticides in fish and sediment which may pose a great danger to the environment. Regular monitoring is therefore required to control the levels of pesticide residues in the water bodies

Multi-Purpose Concept of Design: A Sustainable Strategy in Addressing the Widespread Redundancy of the “White Wedding Gowns” in the Ghanaian Culture
No full textSustainable best practices and material culture are at the forefront in this 21st century, and as a result, sustainability and circularity have become very crucial for global industrial growth and development, and the clothing and textile industry cannot be left out. The clothing and textile industry is considered the second largest contributor to environmental pollution, after the oil industry, and this is due to the fashion industry's adherence to a linear economic system. The alarming rate of this disposable behaviour in the clothing industry requires the adoption of a multi-purpose design concept as a strategy to curb this design stance that may have the potential to extend the life of clothing, encourage sustainable consumption, minimise greenhouse gases and facilitate the transition to a circular economy. The wedding dress is perhaps one of the most common clothing items to be discarded prematurely or become redundant in many wardrobes once the wedding ceremonies are over, meaning that it has become a one-of-a-kind outfit regardless of the time, money and other resources invested in its acquisition. This consumer behaviour is attributed to the lack of innovative design thinking and also the failure to incorporate the needs and values of clothing consumers through the adoption of a co-design strategy. This study is qualitative in nature and therefore employs a mixed-methodological approach, i.e., a combination of interventionist and non-interventionist research methods, to address the study objectives. The thesis has two main objectives (1) to give wedding dresses an extended life within the wedding culture in Ghana by exploring on the one hand the multi-purpose concept of design and on the other hand, product development through co-design with wedding dress wearers; (2) propose a new conceptual model and produce a sample wedding dress through a sustainable prototype to be tested and validated.As melhores práticas sustentáveis e a cultura material estão na vanguarda neste século XXI e, como resultado, a sustentabilidade e a circularidade se tornaram muito cruciais para o crescimento e desenvolvimento industrial global, não podendo a indústria do vestuário e têxteis ser deixada de fora. A indústria de vestuário e têxteis é considerada a segunda fonte que mais contribui para a poluição ambiental, logo após a indústria do petróleo, e isso se deve à adesão da indústria da moda a um sistema económico linear. A taxa alarmante deste comportamento descartável da indústria do vestuário exige a adoção de um conceito de design multifuncional como estratégia para conter essa postura do design que tem o potencial de prolongar a vida útil das roupas, incentivar o consumo sustentável, minimizar os gases de efeito de estufa e facilitar a transição para uma economia circular. O vestido de noiva, talvez seja um dos itens de vestuário mais comuns a ser descartado prematuramente ou a se tornar redundante em muitos guarda-roupa, assim que as cerimónias de casamento terminam, o que significa que se tornou um traje único, independentemente do tempo, dinheiro e outros recursos investidos em sua aquisição. Este comportamento de consumo é atribuído à falta de um pensamento inovador de design e também à falha em incorporar as necessidades e valores dos consumidores de roupas através da adoção de uma estratégia de co-design. Este estudo é de natureza qualitativa e, portanto, emprega abordagem metodológica mista, ou seja , métodos de pesquisa intervencionista e não intervencionista para abordar os objetivos do estudo. A tese possui dois objetivos principais (1) dar aos vestidos de noiva uma vida prolongada dentro da cultura do casamento no Gana, explorando por um lado o conceito polivalente de design e por outro, o desenvolvimento de produto através de co-design com utilizadores de vestidos de noiva; (2) propor um novo modelo conceitual e produzir uma amostra de vestido de noiva através de um protótipo sustentável a ser testado e validado
