A new species, Byssoloma orientale K. Miyaz. & Y. Ohmura, is described from East Asia. It is characterized by a minutely farinose light green thallus, apothecia with a well-developed byssoid margin that spreads laterally over the thallus surface, a pure black apothecial disc caused by the presence of an aeruginous pigment in the epithecium, (7–)9–12(–17)-septate cylindrical colourless ascospores, and oblong conidia. This species grows on living leaves as well as on tree bark. The molecular phylogenetic position of B. orientale within this genus was inferred based on mtSSU sequences, and the species was shown to be closely related to B. vanderystii, which has up to 7-septate ascospores and an absence of aeruginous pigment in the epithecium.
This research communication paper addresses the hypothesis that the use of therapeutic alternatives for mastitis, such as intramammary ozone, can cure the disease with lower costs and without harmful residues for human consumption and without formation of microbial resistance like the ones caused by indiscriminate use of antibiotics in dairy farms. The study was performed in 36 mammary quarters from 12 dairy cows with subclinical mastitis grade three. The experimental units were randomly assigned into four groups and each group received a treatment. Treatments comprised (a) 20 μg/ml ozone gas; (b) 40 μg/ml ozone gas; (c) negative control treatment of 12.5 μg/ml ozonated saline and (d) positive control treatment of 100 mg of cephalexin + 100 mg of neomycin + 10 mg of prednisolone, all by intramammary injection. In all quarters, milk was collected before and after the application of treatments for California mastitis test and evaluation of milk composition, somatic cell count, and bacterial cultures. The results indicated that the use of intramammary ozone did have a therapeutic effect, and whilst this was less than that of antibiotics, ozone does confer some advantages. Treated milk had a good composition, the treatment cost was low, milk withdrawal may not be necessary and there is no risk of antibiotic resistance.
Doctoral studies have remained the most advanced training for potential academics and scholars all over the world. Also, the research products of doctoral studies, that is, doctoral theses, are the flagships of original research efforts from universities and research institutes across the globe. Against this background, this paper examines the growth and development of doctoral training in the Department of History of Obafemi Awolowo University, Ile-Ife. It also provides bibliographic and historiographical analyses of the twenty-nine doctoral theses submitted to the Department in its sixty years of existence from 1961 to 2021. It shows that doctoral research outputs from the Department are based on oral, ethnographic and documentary evidence on major historical developments in the pre-colonial, colonial and postcolonial Yorubaland, Nigeria, and neighbouring West African states like Benin Republic and the Gambia. The article concludes that doctoral training and theses at Ife have resulted in landmark historical publications and have produced renowned historians who are making scholarly waves within and outside Nigeria.
The topic of wisdom attracted much less attention in modern thought than in ancient and medieval times. However, there has been a renewal of interest in it in recent psychology and philosophy, and a variety of questions has emerged from this current work. Aquinas has a detailed and elaborate account of the wisdom which pervades his oeuvre. This paper explores that and seeks to answer some of these contemporary questions from Aquinas's perspective.
Following the devastating fire in April 2021 which destroyed many of the African Studies books in the Jagger Library at the University of Cape Town (UCT), SCOLMA offered to coordinate the donation, selection and shipping of replacement books, working in liaison with UCT librarians.
The study is an experimental and theoretical analysis of the patterns of traffic flows and the possibilities of their distribution on urban street and road networks. It considers and analyses modern approaches that make it possible to improve traffic flow control mechanisms and traffic conditions on a street and road network. Based on the established internal relationships, the paper develops a model of the influence of factors on the level of their priority, which makes it possible to divide them by hierarchy levels and, accordingly, to observe the level of their impact on independent components. The scientific novelty of the research lies in the newly developed method of vehicle traffic control, which involves the distribution of traffic flows along the urban street and road network. The conclusions presented in the study represent scientific and methodological developments and applied recommendations that can be used in urban planning to improve the conditions of transport services in populated areas.
