TL;DR: This paper used the Bill of Rights in the Constitution of the Republic of South Africa 1996 and the jurisprudence that has developed in the course of its application to demonstrate that a human rights framework for the protection of expressions of folklore is a viable, or relatively better, framework than protection through existing intellectual property and sui generis regimes.

TL;DR: In this article, a pinch analysis of the heat exchanger networks in the crude distillation unit of the New Port-Harcourt refinery has been performed, aimed at ascertaining the energy efficiency and operation of heat exchangers used in preheating the crude.
Abstract: The pinch analysis of the heat exchanger networks in the crude distillation unit of the New Port-Harcourt refinery has been performed. This analysis is aimed at ascertaining the energy efficiency and operation of the heat exchangers used in preheating the crude. Process data of the heat exchanger networks (HEN) were collected to formulate a problem table and used in Aspen-Pinch ® software for pinch analysis of the networks. The software produced the composite and grand composite curves, the grid representation and target reports. From these, the minimum heating and cooling requirements of the entire network, the process streams not properly matched and the heat exchangers not properly placed were obtained. The analysis indicated that a total of 98916.1 KW hot utility, 8298.7 KW cold utility were not utilized within the network (poor process stream matching) and that ten heat exchangers were not properly placed. Hence the heat exchangers in the crude distillation unit need to be retrofitted to ensure adequate heat recovery, process to process integration and efficient energy utilization within the network.

TL;DR: In this article, the authors investigated the biodeterioration of classroom wall surfaces in the University of Port Harcourt, Nigeria, using plating and determined the population of culturable bacterial and fungal biodeteriogens.
Abstract: Aim: This study investigated the biodeterioration of classroom wall surfaces in the University of Port Harcourt, Nigeria. Study Design: Scrapings from selected classroom wall surfaces were analyzed for their microbiological and physicochemical parameters. Isolated bacteria were screened for their antibiotics susceptibility. Place and Duration of Study: This study was carried out at the University of Port Harcourt between March - June 2018. Methods: The population of culturable bacterial and fungal biodeteriogens was determined by plating. Physicochemical parameters were determined using standard methods. Antibiotic susceptibility pattern of the bacterial isolates was determined using the disc diffusion method. Results: The total culturable heterotrophic bacterial counts ranged from 6.48 to 8.23 log CFU/g while the total fungal counts ranged from 5.00 to 7.28 log CFU/g. The bacterial isolates identified by biochemical characterization and their frequency of occurrence are Micrococcus spp. (7.3%), Citrobacter spp. (3.2%), Bacillus spp. (39.1%), Serratia spp. (3.2%), Corynebacterium spp. (10.9%), Staphylococcus aureus (20.1%), Proteus spp. (9.2%) and Shigella spp (7.0%). The fungal isolates and their frequency of occurrence are Aspergillus flavus (39.1%), Penicillium spp. (20.1%), Microsporium canis (14.3%), Coccidioides spp. (10.9%), Aspergillus fumigates (3.2%) and Tricophyton spp (3.2%). All antibiotics used showed activity against all bacterial isolates except Proteus spp. From the results of the physicochemical parameters, pH values ranged from 6.15 to 9.01, nitrate ranged from 5.30 to 14.83 mg/kg, phosphate ranged 2.19 to 5.94 mg/kg, sulphate ranged from 12.97 to 19.07 mg/kg and Total Organic Carbon ranged from 74.89 to 119.43 mg/kg. Conclusions: This study has shown the potential public health risk associated with classroom building deterioration owing to the presence of pathogenic microorganisms. Therefore, measures towards prevention and mitigation of classroom building biodeterioration should be in place.

Abstract: A nation’s GDP is an important index reflecting development in economy and incomes. This paper uses the annual data of Nigeria’s GDP from 1981 to 2019 as the research data. An Augmented Dick Fuller test was used to test for stationarity of the data and was seen to be stationary at the second differencing. ARIMA (1, 2, 1) was identified as an appropriate model using Eviews 11 software after comparing the AIC values. The Ljung-Box test of the Residual satisfied that the model was adequate and was used to forecast the out of sample data. And with a Theil inequality of 0.022008, the model forecasting ability is deemed be a good.

TL;DR: In this article, the authors investigated three distinct populations of the ecologically poorly studied rodent Eliomys quercinus, in Spain and Italy, and found that capture probability was higher in northern Italy than in the other two study areas.
Abstract: Comparative aspects of the demography were investigated in three distinct populations of the ecologically poorly studied rodent Eliomys quercinus, in Spain and Italy. Maximum longevity was observed in a Spanish female (survival of at least 2 years and 4 months). For all the populations under study, various closed population models and the robust design model gave similarly reliable estimates for population size, with Jolly–Seber estimates being considerably less reliable. The same result also emerged for the estimates of survival and capture probabilities, but with less profound differences between Jolly–Seber and the closed models with robust design. Average density showed considerable oscillations over the years and across localities, being nearly identical in northern and central Italy but considerably higher in Spain. Survival was considerably higher in Spain than in northern and central Italy. Conversely, capture probability was higher in northern Italy than in the other two study areas.
