Published: June 2020

The study was conducted on “Pricing strategies of Ambo Mineral Water from producers and sellers’ perspectives’’ and a data was collected from sellers of Ambo Town West Shoa Zone Oromia Regional State. The main objective of the study is to see the pricing strategies of Ambo Mineral Water and the scope is delimited to sellers of Ambo Mineral Water found in Ambo Town. The sample size was determined based on the maturity strategies which more used when the responses of the respondents are redundant. Accordingly, the study is used sample size up to 54 to see the facts. To analyze the collected data the study used descriptive statistics for all parties of the study. The last section presents the conclusions and recommendations directed to the respondents. In conclusion, all the respondents have one or two pricing strategies and this implies that the respondents have more knowledge on the pricing strategies. Therefore, it is more essential to recommend all the respondents must have the right pricing strategies according to their offerings based on the customers’ sensitivity.

Published: June 2020

The main purpose of this paper is to respond to the call to re-envision higher education and to share experiences of hope that provide concrete examples about possibilities of enacting liberatory education in higher education. This article focuses on the work of one junior faculty member and four doctoral students who participate in a critical inquiry group and research collective called the “Critical Education Research Collective,” (CERC). As social justice educators, in this shared space we engage in meaningful teaching and inquiry practices that involve teaching and research methodologies, education theory, dialogue, reflection and praxis. While research has highlighted the ways in which inquiry groups can be used as an intentional and systematic examination into teaching practice, this essay describes the structure, functioning, theoretical standpoints and the process of becoming a doctoral student and professor-led critical inquiry group. The group came together as a way to sustain the work and research development of both the doctoral students and the junior faculty in the collective.

Objective – to evaluate agrochemical, allelopathic and microbiological characteristics of the soil environment for Actinidia arguta (Siebold et Zucc.) Planch. ex Miq. plants cultivated in Ukraine and two provinces of China.
Material and methods. The rhizosphere soil was sampled at 0–15 cm layer under A. arguta plants in the stage of fruit ripening in Ukraine (Kyiv city: North of Ukraine, Forest-Steppe zone, a temperate continental climate) and two provinces of China (Shandong: East China, a monsoon temperate zone; and Heilongjiang: Northeast China, continental monsoon climate). The concentrations of carbon, available forms of macro- and micronutrients, phenolic compounds in the soil samples were determined. pH and redox potential of soil were measured. Soil phytotoxicity was studied by direct bioassay method on cress (Lepidium sativum L.) root growth. Microbiological analyses of soil samples were conducted.
Results. The dissimilarities in the concentrations of carbon, macro- and micronutrients in the examined soil samples were shown. The domination of reduction conditions (Eh < 400 mV) in the soils under A. аrguta points the deceleration in the humification processes, as well as the presence of the mobile forms of organic compounds with the allelopathic properties. The redox potential decreased with the increase of pH values. This reflects the intensifying of reduction processes. The soil phytotoxicity under A. аrguta reached 20–70% compared with the control. This is obviously due to the accumulation of phenolic compounds as well as iron and manganese. The relationship between pH, the phytotoxicity and the abundance of the main taxonomical and ecological trophic groups of microbiota in soils under A. аrguta was ascertained.
Conclusions. Calcic Luvisols from the M.M. Gryshko National Botanical Garden of the NAS of Ukraine (Kyiv city, Ukraine) and Luvic Chernozems from Jiamusi (Heilongjiang province, China) were determined to be the most favorable for A. arguta cultivation. Salic Solonetz from Harbin (Heilongjiang province, China) and Haplic Luvisols from Linyi (Shandong province, China) had the least suitable soil conditions for A. arguta plants.
Perfil de contaminação das águas e peixes por metais pesados e suas consequências para a saúde humana: uma revisão de literatura.
Authors: Kapepa Maria 
Published: June 2020

Pode haver contaminação crescente da água e dos peixes por conta dos metais pesados que tem origem no descuido da natureza. Essa contaminação não só prejudica o meio ambiente, mas também acaba contaminando o ser humano, que ingere os metais através da alimentação. Como esses metais não são digeridos no organismo humano, isso traz como consequências doenças congênitas, abortos, infertilidade, entre outras doenças. Esse trabalho tem como objetivo levantar as consequências dos metais pesados no ser humano que ingere peixes contaminados, a partir do estudo da contaminação da água e dos peixes. Esse trabalho trata-se de uma pesquisa exploratória, por meio de uma revisão bibliográfica, feita a partir do levantamento de referências teóricas já analisadas. O nível elevado dos metais pesados comprovado pelas pesquisas feitas na água e nos peixes que podem acumular metais tóxicos a partir de um ambiente poluído. Observaram que a acumulação de íons metálicos na musculatura corporal e no intestino dos peixes seguiu a ordem: Zn > Fe > Mn > Cu > Pb > Hg > Cd e Fe > Zn > Cu > Pb > Hg > Mn > Cd, respectivamente. Esses metais quando entram no organismo humano atingem os órgãos provocando disfunção nos rins, fígado, cérebro, podendo causar infertilidade, atravessar a placenta e causar anomalias congênitas.Com base nesse resultado podemos concluir que os metais pesados podem se acumular no organismo dos peixes e trazer consequências graves no organismo dos seres vivos através da alimentação.
Muslim Poets Under a Christian King: An Intertextual Reevaluation of Sicilian Arabic Literature Under Roger II (1112–54) (Part II)
Authors: Miller Nathaniel A. 
Published: June 2020

ABSTRACT:Throughout the twelfth century, a number of Arabic-speaking Muslims produced poetry in the court of the Normans of Sicily. This article examines literary figures active under Roger II in the context of their interlocutors, professional colleagues, and other contemporaries around the western Mediterranean and North Africa. It argues that, in this context, most of the Sicilian Arab literary figures were only secondarily poets, their primary role being within a chancery or other administrative milieu, and that they continued to assert an undiminished Islamic identity, although living under Christian rule. This identity is mirrored in the intertextual play on topoi (maʿānī) found in Sicilian Arabic poetry, which was heavily engaged with cultural activity around the Mediterranean.

Authors: Onono Joshua Orungo , Kithuka James 
Published: June 2020

Aim: To determine type of benefits from keeping donkeys, challenges facing donkey farmers and how to streamline supply of medicines for treatment of donkeys in Kenya.
Study Design: A descriptive study conducted in selected regions where donkey welfare projects are implemented and other regions without these projects between the months of May and August, 2018.
Methodology: Data collected from donkey owners and users, animal health service providers, regulatory body, and agro-vets using semi-structured and check list questionnaires. A total of 156 questionnaires administered to donkey owners and users and 87 animal health providers.
Results: Benefits of keeping donkeys included income obtained from transportation services, sale of surplus donkeys in a herd and hiring them out for a fee, such income are used for paying school fees for children and medical care. On average donkeys contributed about 20% of household incomes from livestock. Donkeys often suffered from myriad of challenges: infestation with endoparasites, wounds, colic, fractures, lameness, pneumonia, babesiosis, trypanosomiasis and zoonoses including tetanus and rabies. Sale volume for medicines used to treat donkey diseases in agro-vets (shops selling agricultural inputs including veterinary drugs) was approximately 15%, while percentage of donkey cases treated by animal health providers was about 7% of total caseload. Level of need for response to donkey cases by animal health providers was ranked 4th on a priority scale of 1-5. Furthermore, agro-vets did not stock medicines for pain relief. Moreover, differences exist between regions where donkey welfare projects are implemented as compared to other regions on level of knowledge of animal health providers on type of medicines used for treatment of clinical cases in donkeys, requirements for regulation of veterinary practices and types of veterinary providers (P = 0.05).
Conclusions: These results support prioritization of training on early recognition for conditions which compromises wellbeing of donkeys and access to pain relief medicines.

Published: June 2020

To assess the quality of River Onyongo catchment area for agricultural purposes. Field and laboratory assessment was carried out.
Water resources potential assessment was carried out in part of River Onyongo catchments area. The topographical map was used to carve out the study area. Geological mapping of the study was carried out by compass. Field permeameter pits were established in four locations within the study area to determine the coefficient of permeability of sub-surface soils/lithology by Darcy Law. Depth to water table was measured in some selected hand-dug wells. Discharge measurement of River Onyongo rainy season was 199,888.12 litres/second and 2,770.62 litres/second in dry seasons while River Ichow (bridge) had 354.3 litres/second in the rainy season and 195.43 litres/second at the upstream; there was no flow during the dry season. Water samples were collected in the various locations in the study area and analysed in the laboratory. The relief of the study ranges from 100 m to 223 m above mean sea level. The Sodium Absorption Ratio (SAR) of the water sample ranged from 0 – 10 mg/l indicating that water can be used on all crops and all soils. The coefficient permeability/lithology of the study area ranged from 0.36 – 29.5 m/day corresponding to fine-grained sand to medium-grained sand – coarse-grained sand. Recommendations for the use of water for optimal agricultural purposes and production in the study areas were made.

Authors: Adu-Poku Maxwell , Addo Matthew Glover 
Published: June 2020

Aims: This study seeks to investigate the antimicrobial susceptibility profile of urinary tract pathogenic infections in diabetic patients attending a health facility in Kumasi, Ghana.
Study Design: A total of 285 patients were recruited using Cochran’s formula at a prevalence of 26.4% for this study from patients attending the University Hospital from April 2018 to October 2018. Data were collected using a structured questionnaire.
Methodology: Clean-catch midstream urine samples were screened for the presence of pathogenic bacteria and their antimicrobial susceptibility pattern using recommended culture methods.
Results: Out of the 285 patients, 125 (43.9%) were diabetic with 90 (72%) being female and 35 (28%) male. There was no association between UTI’s and gender (P=0.5799) with diabetic patients recording higher bacteriuria compared to non-diabetics (P< 0.001). Isolates from 113 (39.4%) of the samples were identified and these included, Escherichia coli, Pseudomonas species, Klebsiella species, Proteus species and Staphylococcus aureus. The most predominant was E. coli 62 (54.9%) followed by S. aureus 24 (21.2%), Klebsiella species 14(12.4%), Pseudomonas species 12(10.6%) and Proteus species 1(0.9%). E. coli showed a high antimicrobial sensitivity rates against most of the tested antibiotics, gentamycin (90.3%), amikacin (98.4%), nalidixic (34%), cefotaxime (80.6%) and nitrofurantoin (93%). Proteus spp. on the other hand, showed a 100% sensitivity to all the antibiotics except tetracycline, amikacin and cefotaxime. It was observed that Escherichia coli was mostly resistant to tetracycline (96.8%), norfloxacin (69.4%) and cefotaxime (61.4%).
Conclusion: S. aureus showed a higher level of resistance to tetracycline (100%). The prevalence of this study indicated that UTI among diabetic patients was relatively comparable with other studies. Amikacin and nitrofurantoin should be recommended as antimicrobials for the treatment of UTIs whilst the use of tetracycline, norfloxacin and cefotaxime should be discouraged.

Authors: Owusu Samuel Ebo 
Published: June 2020

Aims: To investigate the effects of coconut water treatment and polythene sheet dome on the establishment of Ixora coccinea (L.), stem cuttings.
Study Design: A 4 factorial Randomized Complete Block Design (RCBD) with three replicates was used.
Place and Duration of Study: The study was carried out at the Multipurpose Crop Nursery of the University of Education, Winneba, Mampong campus between September and December 2019.
Methodology: Two hundred and forty (240) cuttings of equal length of 12 cm were excised and each cutting planted to a depth of 2 cm with 10 cm above the soil in each of the 240 potting bags, which were filled, with sterilized soil to a depth of 15 cm from the bottom leaving 1.5 cm from the top.
Results: Results showed that treatments with varying levels of coconut water in combination with the plain polythene dome had a significant influence on growth parameters. Increasing levels of coconut water resulted in a subsequent increase in the number of leaves, plant height, and roots as well as survival rate. The treatment with 100 ml coconut water in combination with polythene dome recorded the highest plant height, number of leaves per plant and number of roots per plant [12.22 cm, 21.89 and 22.00] respectively at the end of the experiment. The percentage survival of plants however reduced significantly by 60 DAP [83.33%] when compared no polythene dome(control) [94.44%].
Conclusion: The study concludes that Ixora coccinea (L.) cuttings treated with 100 ml of coconut water in combination with a polythene dome will enhance the growth and development of Ixora coccinea (L.) cuttings, however, the use of the polythene dome should be curtailed before 60DAP.

Published: June 2020

Background and Aims: Children in contact with adults having pulmonary Tuberculosis (TB) are vulnerable to TB infection and hence contact tracing and screening is important for early detection of infection. However, there are few contacts traced and the prevalence and risk factors for transmission are not well studied. The objective of this study was to determine the prevalence of infection and risk factors associated with TB transmission among under five children in household contact with adult pulmonary TB patients.
Materials and Methods: A cross sectional study was carried out in three health facilities with a high TB burden in Mbale District, Eastern Uganda involving all under five household contacts of adults with pulmonary tuberculosis recorded in the TB register from October 2018 to March 2019 and still on treatment. Structured questionnaires were administered to the index clients to obtain their demographic and clinical data about TB, HIV as well as information on the children. Children were screened using the intensive case finding forms to identify presumptive cases.
Results: The total number of index TB Clients line listed were 70. Number of clients traced was 38, 21 (%) of whom had children under five years and a total of 33 children were identified. The number of presumptive cases was 9/33 (27.27%). 77.8% of the presumptive cases were living in poorly ventilated houses.
Conclusion: The study identified children with presumptive TB and various risk factors for TB transmission. Intensive contact tracing can therefore help reduce TB transmission within the communities. It is recommended to undertake studies aiming at improving contact tracing and strategies to eliminate the risk factors to TB transmission.

Published: July 2002

AbstractObjective: To evaluate the origin of pseudomyxoma peritonei (PMP) in Chinese women. Methods: The clinicopathologic features of 15 cases of PMP were reviewed. Immunostaining using antibodies for CK7 and CK20 was performed in the ovarian, appendiceal and peritoneal lesions of these cases. Results: Appendiceal pathology was documented in five cases, including four mucinous cystadenoma and one simple mucocele. Eight ovarian tumors were found, including seven mucinous cystadenocarcinomas of low malignant potential and one mucinous cystadenoma. Synchronous ovarian and appendiceal lesions were discovered in three cases. One patient had adenocarcinoma of the pancreas. The origin of mucin production was not known in four cases with metastatic adenocarcinoma found in two of them. Immunoreactivity for CK20 was demonstrated in the tissues derived from the peritoneum, ovary, appendix and pancreas while only 23% (3 out of 13 women) of the peritoneal lesions and 33% (2 out of 6 women) of the ovarian tumors were immunoreactive for CK7. Conclusions: PMP is a heterogeneous lesion, which may develop from mucinous metaplasia of the peritoneum or from appendiceal, or ovarian lesions. Careful examination of the ovary and appendix with performance of appendectomy is advised in every case of PMP. Immunohistochemical examination of the peritoneal, ovarian or appendiceal lesions using antibodies, in particular that for CK7 would help in defining the origin of mucin production.
Perceived relevance and quality of POM journals: a decade later
Authors: Barman Samir , Hanna Mark D , LaForge R.Lawrence 
Published: July 2002

AbstractThis research is a 10‐year update on the rankings of perceived relevance and quality of selected Production and Operations Management (POM) journals that was reported by Barman et al. (1991) [Journal of Operations Management 10 (2), 194–212)]. The results show some changes in the perceptions of journals over the past decade. Some journals are perceived to be extremely relevant to POM research, but not particularly of “high” quality. For other journals, the reverse is true — “high” quality is perceived but the published studies are not considered particularly relevant to POM. The Journal of Operations Management remained atop the relevance rankings and retained its position among the top three journals for quality. The study identifies factors that the respondents say influence their perception of journal quality. Finally, the paper finds some evidence that association with the editorial board of a journal affects one’s perceptions of the quality and relevance of that journal.
IL‐16 is differentially expressed in the developing human fetal brain by microglial cells in zones of neuropoesis

Published: July 2002

AbstractMicroglial cells are regulators of tissue homeostasis in the adult central nervous system and readily participate in pathological processes, orchestrating tissue remodeling. Cytokines produced by microglial cells are markers of cell activation and contribute to reactive processes. In this paper, we have studied the expression of IL‐16 (leukocyte chemoattractant factor), a natural soluble ligand to the CD4 molecule, in human fetal brains from the 11th to the 20th. week of gestation by immunohistochemistry. Interleukin (IL)‐16+ cells were detected already at the 11th gestational week, accumulating with aging in cortical layers (P<0.0001) at the 16th and 19th week, and reaching maximum numbers in the 20th week. Most IL‐16+ microglia (>80%) revealed morphological hallmarks of activated microglia. We observed that IL‐16 cells coexpress LCA (>80%) and MRP‐8, an activation‐associated Ca2+ binding S‐100 family member (>80%). In contrast, only few IL‐16+ cells proliferated (PCNA+, 20–40%) or co‐expressed the HLA‐DR, ‐DP, or ‐DQ antigen (<10%), and rare coexpression with CD68 (20–40%) was detected until 17th week. No coexpression with CD4, CD8 or CD20 was detected. Furthermore, we observed accumulation of IL‐16+ microglia in zones of neuronal proliferation, migration and differentiation. Increasing numbers of IL‐16+ cells were detected in bordering zones adjacent to the basal ganglia. Our data suggests that the early presence of IL‐16+ microglia exert a CD4‐independent function‐mediating activation, and chemotaxis of microglia precursors during neuronal development. In addition, IL‐16 immunoreactivity might be a helpful tool to determine distinct developmental stages of microglial cells during fetal central nervous system ontogeny.
Otx genes in the development and evolution of the vertebrate brain

Published: July 2002

AbstractMost of the gene candidates for the control of developmental programmes that underlie brain morphogenesis in vertebrates are the orthologues of Drosophila genes coding for signalling molecules or transcription factors. Among these, the orthodenticle group, including the Drosophila orthodenticle (otd) and the vertebrate Otx1 and Otx2 genes, is mostly involved in fundamental processes of anterior neural patterning. In mouse, Drosophila and intermediate species otd/Otx genes have shown a remarkable similarity in expression pattern suggesting that they could be part of a conserved control system operating in the brain and different from that coded by the HOX complexes controlling the hindbrain and spinal cord. In order to verify this hypothesis, a series of mouse models have been generated in which the functions of the murine Otx genes were: (i) fully inactivated, (ii) replaced with each other, and (iii) replaced with the Drosophilaotd gene. The data obtained highlight a crucial role for the Otx genes in specification, regionalization and terminal differentiation of rostral central nervous system and lead to hypothesize that modification of their regulatory control may have influenced the morphogenesis and evolution of the brain.
