Cycling as a means to improve the health and Wellbeing of both locals and visitors of national parks
No full textThe cause of numerous illnesses are obesity, anxiety, and hypertension. Physical activity reduces the higher risks of factors associated with various cardiovascular diseases. Cycling is a prominent type of physical activity. Locals, as well as visitors, can perform cycling. It is important to motivate locals and visitors coming to National Parks to reduce car usage and enhance bike usage; this can be achieved by highlighting the associated health benefits and reduced risk of diseases. Past research has identified many methods to promote cycling usage by highlighting its advantages, such as reducing the effect of multiple diseases e.g. all-cause mortality, cancer mortality, cardiovascular diseases, and obesity morbidity. This research, via literature review, identifies the health and wellbeing benefits. Additionally, it proposes a few strategies (healthy streets, kilometre allowances, and cycle superhighways), along with an implementation approach, to promote cycling within and around National Parks
Biogas to liquefied biomethane: Assessment of 3P's–Production, processing, and prospects
No full textSustainable scale-up of biomethane to overcome the dependency on fossil energy sources is still not matured, fundamentally owing to its production and availability at a lower pressure (i.e., atmospheric) compared with the conventional natural gas. This is a fundamental assessment that specifically aims to overview the biogas production, cleaning technologies, upgrading technologies, and possible biomethane liquefaction technologies. The digestion technologies for biogas production are analyzed in terms of their important operating and performance parameters corresponding to optimum digester operation. The cleaning and upgrading technologies are assessed corresponding to their competitive factors, merits, and associated challenges. Cryogenic separation relies on different technologies that are based on different mechanisms (anti-sublimation, distillation, etc.). These technologies have been recently studied for CO2 removal from high CO2-content natural gas, showing promising results for application to biogas upgrading, in particular if the final goal is liquefaction. Since liquefaction itself is an energy- and cost-intensive process, cryogenic separation is synergistic in obtaining upgraded and liquefied biomethane in a single process unit, instead of integrating liquefaction with other upgrading technologies. Among all available liquefaction technologies, the nitrogen expander-based liquefaction processes are most promising candidates to produce liquified biomethane (LBM), mainly due to small investment costs, simple operation, and compact design. This study suggests that there is a need to design energy-efficient small-scale biomethane liquefaction processes following biogas upgrading. Thus, incorporating biogas in the energy mix would result in economic, environmental, and climate benefits, globally
Design of evolutionary computational intelligent solver for nonlinear corneal shape model by Mexican Hat and Gaussian wavelet neural networks
No full textIn this study, an integrated computational intelligence algorithm is implemented for the numerical treatment of the two-point boundary value problems that arise in the nonlinear corneal shape (NCS) model through the exploitation of wavelet neural networks including Mexican-Hat (MHWNNs) and Gaussian-wavelet (GWNNs)
through global genetic algorithms (GAs) then hybridization with local sequential quadratic programming (SQP) solvers, i.e. MHWNNsGAs, GWNNs-GAs, MHWNNs-GA-SQP, and GWNNs-GA-SQP respectively. The GWNNs and MHWNNs are applied to calculate the mean squared error of mathematical modeling of the proposed problem through objective functions while optimization of the fitness functions is initially conducted with an efficiency of global search GAs and then the efficacy of local search technique SQP for fine-tuning. A comparison of the proposed solutions of MHWNNs-GAs, GWNNsGAs, MHWNNs-GA-SQP, and GWNNs-GA-SQP solvers with a reference solution of Adam’s method shows that the proposed schemes have better accuracy, stability, efficiency consistency on an independent number of runs analyzed through complexity analysis and different statistical operators
Assessing Fitness-To-Drive among Older Drivers: A Comparative Analysis of Potential Alternatives to on-Road Driving Test
No full textTo enable older drivers to maintain mobility without endangering public safety, it is necessary to develop more effective means of assessing their fitness-to-drive as alternatives to an on-road driving test. In this study, a functional ability test, simulated driving test, and on-road driving test were carried out for 136 older drivers. Influencing factors related to fitness-to-drive were selected based on the correlation between the outcome measure of each test and the pass/fail outcome of the on-road driving test. Four potential alternatives combining different tests were considered and three modeling techniques were compared when constructing the fitness-to-drive assessment model for the elderly. As a result, 92 participants completed all of the tests, of which 61 passed the on-road driving test and the remaining 31 failed. A total of seven influencing factors from all types of tests were selected. The best model was trained by the technique of gradient boosted machine using all of the seven factors, generating the highest accuracy of 92.8%, with sensitivity of 0.94 and specificity of 0.90. The proposed fitness-to-drive assessment method is considered an effective alternative to the on-road driving test, and the results offer a valuable reference for those unfit-to-drive older drivers to either adjust their driving behavior or cease driving
Design of stochastic computational Levenberg Marquardt backpropagation-based technique to investigate temperature distribution of longitudinal moving porous fin
No full textAbstract The improvement of thermal exchange is of utmost interest in a wide range of engineering areas. The current study focuses on thermal evaluation involving natural radiation and convection in a fractionally arranged moving longitudinal fin model placed under a magnetic field. We implement the Levenberg Marquardt backpropagation (LMB) algorithm for investigating an innovative use of stochastic numerical computation for analyzing the efficiency of the temperature distribution in a porous moving longitudinal fin. The datasets for LMB have been created using a shooting approach for dynamic systems with varying ranges of different parameters. The validation, testing, and training processes are used to simulate networks using the LMB approach for diverse scenarios of moving porous fin models. The reliability of results is assessed based on the regression measures, absolute error, error histograms, mean square error, and other metrics for fuller numerical modeling of the suggested LMB to investigate the thermal efficiency and effectiveness of porous moving fin
Phytochemical isolation and biological screening of Cotoneaster microphyllus
No full textThe root and aerial parts of Cotoneaster microphyllus were subjected to extraction and isolation of phytochemicals. The extracts were evaluated for their antioxidant anthelmintic, antimicrobial, and anticholinesterase potentials using standard protocols. Crude extract of aerial parts and roots, more potently scavenged DPPH free radicals with IC50 values of 83 and 66 μg/mL while ABTS with 92 and 90 μg/mL respectively. Chloroform fraction exhibited highest anthelmintic activity followed by ethyl acetate fraction. Ethyl acetate fraction produced high zone of inhibition against selected bacterial and fungal strains. Maximum phenolic contents and vitamin C were found in the ethyl-acetate and chloroform fractions and were therefore, biologically the most potent fractions. Ethyl acetate fraction exhibited highest anticholinesterase potential and was therefore subjected to silica gel column chromatography which resulted in the isolation of one new (1) and four known (2–5) compounds. The isolated compounds were also screened for anticholinesterase potentials. Compound 3, most potently inhibited acetyl cholinesterase and butyryl cholinesterase with IC50 value of 66 and 114 μg/mL, respectively. The extracts exhibited antioxidant, anticholinesterase, anthelmintic and antimicrobial potentials that should be further subjected for the isolation of other responsible compounds in pure state. As anticholinesterase compound 3 is a good candidate to be tested in animal models

The Arab people and the early Islamic period
No full textThis MA thesis, entitled The Arab People and The Early Islamic Period, has been written in response to the post 9/11 interest in the Arab people and early Islam among Western academics. It gives a brief account of pre-Islamic Arabia, the beginnings of Islam and the philosophies and ideologies contained in the religion in an attempt to address the following two fundamental questions: 1. Are there any real grounds for the widely-held perception of the Arab people as a backward race, uncivilised, fragmented, unwilling to develop and making no contribution to the international community? Does their history support this perception? 2. Do the origins of Islam and the way it developed and expanded during its earliest days support current criticisms that Islam itself is an inherently violent religion? A study of the theories of the Arabs as a Semitic race, their geographical distribution and civilisations, the tribes of pre-Islamic Arabia and the ruling powers which influenced the region up to the 6(^th) century will be presented, before an examination of the origins of Islam, from the birth of the Prophet Muhammad in AD 570 to the death of the fourth Caliph in AD 661. It was during this period that Islam reached its zenith as a religion. During this time the essential, fundamental Islam can be surveyed - before imperial Islam was born, before it was adapted to suit differing needs and before it fragmented into sects. All original knowledge of Islam came from this period, what followed merely being derivatives of it. By examining the nature of the expansion of Islam - whether it was spread by military force or through trade and missionaries - we attempt to address questions concerning the Prophet’s confrontations with the enemies of Islam. Were he and his caliphs impoverished, power-seeking imperialists or did they just respond to challenges resulting from what they saw as a duty to make the Prophet's ideology known to people? The conclusion will argue that the Arab people, those of pre-Islamic Arabia as well as those of today, are direct descendents of the early inhabitants of the Arabian Peninsula, bound by common history and language with no ancestral discontinuity. Arabia is the birthplace of the earliest civilisations and has always been the home of many religions and ideologies. This region has always played an important role in other civilisations, in terms of imperial expansion, trade and the exchange of ideas. Many of its qualities were adopted and encompassed within those other civilisations. That Arabia became the birthplace of Islam seems natural, given that it has always been a region rich in ideas. Its emergence was also timely, as the other two monotheistic religions had been, coming at just the right moment for humanity. Islam embraces other faiths and religions, does not call for the enslavement of mind or body and does not encourage violent acts. The negative perceptions of Arabs as anti-establishment and violent and of Islam as a dangerous religion which threatens humanity is ill-founded. The reactions to Islam currently being witnessed mirrors events of 7(^th) century when the Byzantine and Sassanian superpowers sought to secure land and natural resources under the pretext of ideological differences. It is likely that this region will always be a theatre of conflict, due to its geographical location as a crossroads between continents. This study is divided into the following four chapters (excluding introduction and conclusions):Chapter 1 ： Ancient Arabia and the World Leading to the 6(^th) Century Chapter 2: Prophet Muhammad and the Birth of Islam Chapter 3: The Rāshīdūn Period Chapter 4: Islam - The Ongoing Legacy. In surveying and summarising such a large span of time, from the early history of man up to the century, this work gives a broad overview rather than going into great detail on any of the topics covered. Whilst referring to other civilisations, such as ancient Egyptian, Greek and Persian where pertinent, this work focuses on the Arabian Peninsula and on the civilisations within that geographical region. In addition, there are few references from the time of the early Muslim expansion which reflect the opinions of opposing sides. References from the 9(^th) century onward are more widely available. Therefore, it was decided that presenting a history of the misrepresentation of Islam was beyond the scope of this MA. given that extensive research would need to be carried out in order to present an accurate, balanced account. This work is addressed to non-Arabic speaking readers. Regarding research, a decision was made to rely for sources on Western books and references easily available to examiners and readers. It was considered that the use of Arabic references could prove problematic, as understanding them without full knowledge of the Arabic language would be difficult. As there is no linguistic aspect to the scope of this thesis and given that it is addressed to non- Arabic speaking readers, a standardised simplified transliteration system has been used
