Evaluating the Economic Performance of Reverse Polymerization Technology for Waste Tyre Recycling in Sub-Saharan Africa

The unlawful and uncontrolled disposal of waste tyres is greatly disturbing in terms of the environmental concerns and the economic misfortune. In combating this menace, there is growing interest in the application of efficient and environmental-friendly alternatives to the traditional recycling methods for waste tyres. Pyrolysis can be considered as an appropriate non-conventional method for complex materials such as tyres. Several works have been made to improve pyrolysis process towards higher yield and quality of biofuels and greater energy efficiency. This study considers Reverse Polymerization, a microwave-assisted pyrolysis process to extract complete yield and higher quality of valuable products, while avoiding toxic emissions into the environment. The feasibility of such innovative recycling process in Sub-Sahara Africa is essential in order to convince concerned authorities to buy into such advanced technologies with great benefits. The investment analysis and economic performance indicators from the study demonstrated that the operation of such proposed recycling system in the continent is economically feasible. However, the operation of such facility under the present market conditions might highly be challenged by high investment risk as the project is highly capital intensive.

To Analyze the Casual Effect of Economic Growth, Energy Use on Fossil Fuel Consumption in Sub Saharan Africa with Structural Breaks

The study seeks to investigate the casual effect of the efficient energy use and GDP (economic growth) on fossil fuel consumption (Nonrenewable) for the sub Saharan Africa for the period 1980 to 2014. The study also seeks to investigate solutions to environmental issues. Zivot-Andrews unit root test with a structural break, Phillips and Perron unit root test with structural break revealed that the investigated variables become stationary at first-differences. The Gregory-Hansen cointegration test with a structural break shows efficient energy use, economic growth and energy consumption are co-integrated. The long-run estimates obtained from the VECM model indicate that in account of the changes in the structure of the economies, the environmental Kuznets curve does not exist due to validity of a U shaped curve. An increase in output growth (GDP) and efficient energy use positively affect environmental pollution. Based on the findings of this study, the study recommends investment in green technology as the economy growths.

Mechanisms of Resistance to Kinase Inhibitors and Strategies to Prevent the Development of Drug Resistance

Targeting mutant proteins and associated signaling pathways of driver oncogenes by small molecule kinase inhibitors (KIs) are a promising strategy of cancer therapy. However, despite the initial success of treatment, KIs often become ineffective as intrinsic and acquired resistance. This article reviews the English-language literature to explore the underlying mechanisms of drug resistance and to present a challenge for developing drugs to overcome resistance. Mechanisms of acquired resistance include 1) the selection of pre-existing subclones with other mutations, 2) the emergence of secondary mutations in the target kinase domain, 3) upregulation of kinases both within the same kinase family and their related kinase families, as well as activation of alternative bypass pathways, 4) epithelial-mesenchymal transition, 5) overexpression of pro-survival Bcl-2 family proteins and 6) drug efflux mechanisms. Currently available methods are to obtain tumor biopsy samples at recurrence or progression if the tumor lesion is accessible to a biopsy and to use the second- and third-generation KIs based on the individual need of each patient. Furthermore, recent computational challenges provide design principles to prevent the development of drug resistance. In conclusion, we provide an overview of the postulated resistance mechanisms and highlight the future direction of computational structure-based design of new potent KIs.

Epiphyseal Closure of Femur, Tibia and Fibula of the Paca (Cuniculus Paca, Linnaeus, 1766)

After capybara, paca (Cuniculus paca) is the largest rodent in the neotropical region and the body weight varies from 5 to 10 kg, and may reach up to 14 kg. They are animals that reach sexual maturity at around 10 months of age. The aim of this research is to examine, through radiography, the femur, tibia and fibula of the paca. The animals were anaesthetized for radiographic exams. At 6 months of age, the growth line of the femoral proximal epiphysis ceases to perform its functions. At 12 months of age, there is the closure of the line growth of distal femoral epiphysis. At the paca’s tibia, at 12 months old, there was the closure of the growth of the proximal epiphysis. In the distal epiphysis, the closure of the line growth also occurred at 12 months old. At the paca’s fibula, the bone activity of proximal epiphysis ceases with only 23 months old. The distal fibular epiphysis ends its development with 15 months. There are similarities and differences relative to the closure of the pacas’ epiphysis femur, tibia and fibula comparing with dogs and cats.

Upper Oesophageal Foreign Body with Acute Drooling in a Child with Congenital Hypotonia

Foreign body ingestion and aspiration commonly affect children. The most vulnerable age is early childhood when children tend to explore new objects with their mouths or by an accident by elder siblings. A 2-year-old female child who is known to have congenital hypotonia, status post laparoscopic fundoplication and gastrostomy tube feeding (G- tube) inserted at age one year. Then she was in stable condition till when presented with acute unexplained drooling of frothy whitish secretions, mild cough and difficulty breathing with hypoxemia. X-ray chest and upper abdomen revealed normal. She underwent flexible bronchoscopy revealed normal and then direct laryngoscopy was extracted a covering plastic of the feeding tube in the upper end cervical oesophagus by Magill forceps technique. Subsequently her symptoms resolved completely. To increase the likelihood of identifying foreign body ingestion and aspiration, healthcare professionals should maintain a high index of suspicion even in children with neuromuscular disorder.

Obesity and its Correlates among Junior High School Children in the Accra Metropolis

The prevalence of obesity is on the increase worldwide due to changes in diet and physical activity patterns. Childhood obesity is now a major public health challenge in advanced economies. Obesity in childhood tends to persist into adulthood and to predispose to non-communicable diseases. There is little data on childhood obesity and its correlates and determinants in sub-Saharan Africa. A cross-sectional study was carried out using simple random sampling technique to select 260 junior high school children aged 11-15 years from six basic schools (n=768) from three different socioeconomic (low, middle, high) areas of Accra, the capital city of Ghana.
