The land in the Aoulai watershed in the Rif mountain area of northern Morocco has been deteriorating continually due to several different forms of erosion. The Aoulai watershed is essentially characterized by the domination of weak resistance of the rocky formations and its sensitiveness to other major internal factors that result in a conspicuous impetus for both mass movements and water erosion.Water erosion is seen as the most damaging phenomenon for nature in northern Morocco because it acts as an obstacle to the natural balances and seems to have greater effect on the slopes, through the influence of both human and natural factors.
To assess and examine the erosion phenomenon, we have chosen to conduct a qualitative assessment of water erosion in the Aoulai watershed using the PAP-RAC (Priority Actions Programme/Regional Activity Centre) Guidelines. This is the methodology that is most widely applied and implemented both for determining and identifying the areas at risk of erosion and for supporting projects to reduce the degradation that has become a major threat to hydraulic structures including dams, irrigation pipes and other infrastructure elements, which are damaged by the erosion phenomenon in the Central Rif mountains of northern Morocco.

Nowadays, there is an increasing trend to use aromatherapy for treatment of various diseases. Cymbopogon citratus (Lemongrass) is one of many plants which have been reported to employ successfully in aromatherapy. Herein we decided to explore the protective role of Cymbopogon citratus essential oil (CCEO) against hepato/renal damage and genotoxicity induced by carbon tetrachloride (CCl4) and the relation of this bioactivity with its chemical constituents. Six main groups of mice (five/each) were examined: I- represents negative control group, II and III- mice received oral treatment with CCl4 (1mL/kg, positive control) and CCEO (0.3 mL/kg, control plant) respectively for five consecutive days and IV-VI- represent groups of mice treated with CCEO at the three concentrations 0.1, 0.2, 0.3 mL/kg plus CCl4 (five consecutive days treatment). Remarkable adverse effects of CCl4 in all the tested parameters were recorded. These effects were distinguished as an increment in the level of all liver marker enzymes (ALT, AST, ALP, γ-GT), blood urea, and creatinine. Also the oxidative stress biomarkers: malondialdehyde (MDA) and glutathione-transferase GST were affected after CCl4 treatment. Regarding to the genotoxic effect of CCl4, the percentage of chromosomal aberrations in bone marrow and spermatocyte cells was elevated (p< 0.05) compared with the negative control. Notable antioxidant, hepato/renal protection and anti-mutagenic potency of CCEO against CCl4 were demonstrated with a dose-related relationship. GC/MS analysis demonstrated the presence of 12 phytochemical constituents which in combination play a critical role in its antioxidant/antigenotoxic efficacy. The major components exist were E. Citral (35.13%) and Geraniol (32.83%).

In Brazil, the nutritional requirements of the blueberry are not sufficiently known, thus requiring further research on the management of mineral fertilization. In this perspective, this work aimed to evaluate physiological attributes of Southern Highbush blueberry plants cv. Biloxi as a function of nitrogen fertigation in Brasília-DF. The experiment was conducted from August 2018 to July 2019, in the Fruit Sector of the Experimental Biology Station of the University of Brasilia (UnB), Federal District. This experiment adopted a randomized block design, with four treatments: 10; 20; 30, and 40 g of N plant-1, 8 replications, and 5 plants per experimental plot. The following variables were measured: net photosynthesis rate (A), transpiration (E), stomatal conductance (gs), internal CO2 concentration (Ci), instantaneous water-use efficiency (WUE), carboxylation efficiency (CE), SPAD index (SPAD) and leaf nitrogen (N). There was an effect of the different nitrogen doses applied on the physiological attributes. The plants of the blueberry cultivar Biloxi increased their photosynthetic rates at doses up to 30 g of N plant-1. Nitrogen rates did not influence stomatal conductance nor did they provide improvements in the carboxylation efficiency of the blueberry plants. Under the conditions of the present work, the highest N leaf contents were obtained with the application of 30 g N plant-1, and values above this concentration did not correspond to higher net photosynthesis rates, transpiration, and CO2 concentration in the leaf mesophyll.
HISTÓRIA DA CARTOGRAFIA DO RIO PEPERI-GUAÇU E A FORMAÇÃO DO ESPAÇO DO EXTREMO OESTE CATARINENSE
Authors: Luiz Scartazzini Bocalon Vitor , Otsuschi Cristina 
Published: May 2020

O rio Peperi-Guaçu, marco de fronteira entre Brasil e Argentina, no atual extremo oeste catarinense, teve seus primeiros registros por padres inacianos que desenvolviam trabalhos de catequização na Bacia do Prata, entre os séculos XVII e XVIII. O rio servia de caminho natural entre as bacias dos rios Iguaçu, a norte, e Uruguai, a sul e, adquiriu importância estratégica no desenvolvimento dos povos jesuítas do Guayra (atual estado do Paraná) e Sete Povos (Rio Grande do Sul). O principal objetivo foi caracterizar o rio Peperi-Guaçu com base nos mapas Paraquaria Vulgo Paraguay Cum Adjacentibus, de 1670, o Paraquaria Provinciae cum adiacentibo novíssima descriptio, de 1732, ambos de produção inaciana, bem como o Mapa dos confins do Brasil, com as terras da Coroa de Espanha na America Meridional, de 1749 e o Mappa da demarcação que por ordem de S. M. F. e C. fez no anno de 1759. A cartografia inaciana da região, serviria de fonte para a execução dos Mapas das Cortes, sobre o qual se desenhou a fronteira entre os domínios espanhol e português na Bacia do Prata. Somente no ano de 1759, o rio Peperi-Guaçu seria efetivamente cartografado conforme requisitos estabelecidos no Tratado de Madri em 1750.

A Case Study on School Innovation and Change
Authors: Walker Aneta 
Published: May 2020

The implementation of the rigorous, complex Common Core State Standards (CCSS) has prompted schools to initiate change in traditional organizational structures. The CCSS have required teachers to have a deeper understanding of subject matter and specialized content instruction to effectively teach the standards. There is a vast amount of research on educational change as related to school improvement, however, this research analyzed how schools create a context for change to implement a new innovation and improve the learning environment.

The purpose of this research study was to evaluate the effectiveness of an innovative hybrid schedule in improving student learning outcomes and school culture. This mixed-method research study used data generated by the Stages of Concern Questionnaire (SoCQ), AdvancEd®’s Stakeholder Feedback Survey, ACT Aspire® Student Achievement Tests, and teacher interviews. The conceptual framework of the case study was based on the five attributes of the PLCs identified through the work of Shirley M. Hord (2004) and Michael Fullan’s Educational Change Theory (2007). The results of this study indicated the implemented innovation had a significant impact on school culture based on the two administrations of the AdvancEd®’s Stakeholder Feedback Survey. Additionally, student learning outcomes measured by ACT Aspire® Reading and Mathematics Student Achievement Tests showed statistically significant improvements in both reading and math. Lastly, the analysis of teacher interviews supported the findings in the quantitative data.

Broadcasting in the local language in Ghana, especially on radio, has come under stakeholder criticisms over years. The National Media Commission (NMC) Ghana's independent media regulator introduced the Guidelines for Local Language Broadcasting (GLLB) in 2009 as a counterweight to guide the reputation of local language broadcasting. Ten years down the line, the criticisms continue against a backdrop of NMC'S failure to make its impact felt and not being effective in popularising the GLLB among the local language media fraternity. Using interviews, observations and content analysis of the GLLB, the study enhances the GLLB'S implementation by local language radio stations in Ghana with all the perceived challenges. The study found out that for the GLLB to be effectively implemented, the NMC needs an elevation to the status of an Authority in order to command enormous power to exercise. The tenets of the GLLB also need to be re-visited and revised from a Guideline into a Standard, after consultations with the relevant stakeholders.

High morbidity and increase in the number of registrations of breast tumours in dogs, their wide application as biological models, discussion of numerous questions of oncogenesis, and the lack of a uniform/unified methodological approach to the study of molecular and biological mechanisms of treatment of cancer determine the relevance of the problem of cancer both in humans and in our domestic companions. The analysis of publications allowed us to establish the following patterns of carcinogenesis. The peculiarities of the biological behaviour of breast tumours depend on their pathomorphological structure. Genetic predisposition to breast cancer is characteristic only in the single breed aspect. Environmental factors are of critical relevance to carcinogenesis : chemical pollutants initiate oncogenesis indirectly – by altering the expression of several receptors, impaired endocrine balance and direct mutagenic effects. Reproductive status plays a key role in the initiation and progression of breast tumours by reducing the expression of estrogen, progesterone and prolactin receptor genes. The inflammatory response that accompanies the neoplasia process is characterized by increased production of cytokines, cyclooxygenase-2, interleukins (IL-1, IL-6, IL-8), vascular endothelial growth receptors, and impaired hemostatic status (oxidative stress), which promotes progression of disease. In breast cancer in dogs, genomic instability leads to genomic aberrations, and subsequently, mutations that support the proliferation, survival and dissemination of neoplastic cells. The initiation and progression of mammary gland tumours is provided by cancer stem cells by disrupting the regulation of precursor cell self-renewal, which also predispose to resistance to chemotherapeutic agents, radiation, and hormonal cancer therapy. The analysis of the publications revealed the major markers of carcinogenesis that could potentially be used as biological targets for the design of modern diagnostic strategies and high-performance therapeutic protocols.

Published: May 2020

Polychlorinated biphenyls are one of the most dangerous compounds for human health and the environment and are included to Annex C of the Stockholm Convention on Persistent Organic Pollutants. Since Ukraine joined the Stockholm Convention in 2007, the National Implementation Plan of the Stockholm Convention provides the environmentally sound disposal of polychlorinated biphenyls, as well as creation of a monitoring system and sharing information about toxicants. Polychlorinated biphenyls’ have fire resistance, low volatility and stability. Therefore, these substances have been widely used in industry, but on the other hand, they are a problem for the environment. The main hazardous properties of polychlorinated biphenyls are bioaccumulation, stability in the environment, the possibility of formation in accidents (especially in fires) of extremely persistent and toxic aromatic compounds, such as dioxins and furans. Toxic responses to polychlorinated biphenyls are: acute lethality; body weight loss; carcinogenesis; dermal toxi­city; fatty liver; genotoxicity; hepatomegaly; immunosuppressive effects; neurotoxicity; porphyria; reproductive and developmental toxicity; thymic atrophy; thyroid hormone-level alterations. The most likely risks of polychlorinated biphenyls contamination in Ukraine are in the areas of operation, repair or storage of electrical equipment. According to quantity, the leading regions for accumulated polychlorinated biphenyls in Ukraine, are Dnipropetrovsk (459 tons), Volyn (280 tons) and Kyiv regions (255 tons). A comprehensive approach to reducing the risk of polychlorinated biphenyls for human health and the environment involves the improvement of the regulatory framework for managing in all stages of “life cycle”. Obtaining complete and accurate information on the volumes and forms of polychlorinated biphenyls accumulation and creation of modern effective technological support for polychlorinated biphenyls’ degradation are a necessary part of environmentally sound management of polychlorinated biphenyls in Ukraine. The “Polychlorinated Biphenyls Database in Ukraine” information system (2017) was created as a National Polychlorinated Biphenyls Registry in Ukraine. It was designed to systematize, structure, and analyze the large amount of information collected during the inventorising of polychlorinated biphenyls. The best technology of polychlorinated biphenyls degradation must not only provides a high degree of polychlorinated biphenyls’ destruction, but also not lead to the formation of new toxic compounds.

In 2017, Ukraine ranked in the top three among European countries in terms of measles incidence, and ranked first in measles growth in 2018. High morbidity, mortality and development of complications make the problem of knowing features of the measles clinical course, timely diagnosis and active prevention highly relevant. The purpose of the research is to study the dynamics of the incidence and clinical features of measles in children during the outbreak of 2018–2019 in the city of Mariupol, Donetsk region. A peculiarity of the measles outbreak in 2018–2019 in Mariupol is prevalence of the disease in preschool children (60.4%), inclu­ding 30.2% – those under one year of age; low vaccination rate: 52.3% of children unvaccinated; only 22.2% of children were vaccinated twice, according to the schedule. In all age groups, a moderately severe measles course prevailed (69.8%). The clinical course of measles in preschool and school age children had definitive features. Thus, Belsky–Filatov–Koplik spots were observed three times more frequently in preschool children than in schoolchildren (63.9% and 23.3%, respectively). Abdominal pain and diarrhea were only observed in children under 6 years of age (30.2%). Skin pigmentation was absent in children under one year of age and was detected in preschool and school-age children (69.8%). Skin sloughing was only observed in schoolchildren (10.4%). Severe disease course occurred in patients of all ages (29.3%), but children aged under one year and preschool children with severe disease were two times more numerous than those of the school age. Among the observed complications, the vast majority were associated with the respiratory organs: pneumonia (38.3%), subcutaneous emphysema (1.7%), bronchitis (53.2%), laryngitis (3.3%), otitis media (5%). No fatalities were observed. The city should form a commitment to immunization, restore public trust in vaccination, using all forms and means of information, and develop a program to implement the vaccination schedule into practice.
