Desse modo, este estudo objetiva principalmente debruçar-se sobre o conceito de educação ambiental, relacionando-o à sua aplicabilidade nas salas de aula a fim de possibilitar estudantes mais conscientes ambientalmente e que executem ações mais sustentáveis. Assim por meio de uma pesquisa bibliográfica de natureza qualitativa, este estudo chegou à conclusão de que a escola precisa trabalhar transversalmente a questão da preservação do meio ambiente e de modo contínuo, tendo em vista que isso é pauta urgente da sociedade global e essas mudanças de comportamento precisam ser assumidas como uma responsabilidade de todos desde a primeira infância.
Por uma Educação mais Conectada
Authors: Lima Sueleide Alves de Souza
Published: April 2024

A educação tem passado por transformações internas de modo muito acelerado e ressignificado, cabendo aos pesquisadores, educadores e, ainda, os próprios estudantes compreenderem que a aprendizagem se apresenta de forma mediada e, quase sempre, sofre influência de recursos tecnológicos. Em paralelo a isso, há todo um contexto de investimentos que não entra em compasso com as necessidades da escola e, consequentemente, dos estudantes, já que não se faz inserção de tecnologia nas salas de aula sem investimento em recursos tecnológicos e insumos de conectividade. Com isso em tela, este estudo de ordem bibliográfica objetiva discorrer sobre a temática da tecnologia associada ao ensino na escola, considerando o aluno da hodiernidade e os desafios vivenciados pelas instituições para o uso das Tecnologias da Informação e Comunicação. Com análises qualitativas, foi possível evidenciar que não é mais possível se ter uma escola desconectadas, alunos sem acesso à informação de modo virtualizado e professores sem formações específicas para inserirem os recursos tecnológicos na escola.

Published: April 2024

Introduction: The World Health Organization (WHO) has recently included fungi in the list of priority pathogens. The pathogenic yeast C. albicans is responsible for candidiasis in the mouth, throat and esophagus due to its high antifungal resistance and responsible for the number of deaths. In recent years there has been a considerable increase in interest in the practice of phytotherapy, mainly due to the emergence of new fungal strains resistant to antifungals. Herbal compounds have been used in medicine and dentistry for centuries. A classic example is the use of clove oil to treat tooth decay, and eugenol, its main active ingredient, is still used today in daily dental practice. They have been widely studied for their therapeutic grade, for biological and pharmacological tests and for their chemical constituents. Objective: In this integrative review study, the effects of essential oils, their potential benefits for use and their constituents on fungal micromorphology will be evaluated regarding their biological properties in the context of oral health care, helping to expand the knowledge of their mechanisms of action, in addition to provide an overview of the current literature. Methodology: Two indexed search databases Lilac and Pubmed were consulted in March 2024. The words "DENTISTRY" AND "VOLATILE OILS" and "antifungal" and Boolean AND were used, and 11 articles were found that were analyzed. Inclusion criteria: be in agreement with the proposed theme, in the free articles version. Exclusion criteria: not agreeing with the proposed theme. Results: The resident microbiota of the mouth is quite diverse, eight species of the genus Candida were considered pathogenic, and Candida tropicalis and Candida krusei, are associated with the pathological process, especially to promote the formation of biofilms and increase drug resistance. The herbal medicines used for the treatment of oral diseases in the studies showed antifungal activity and can also be used as an antiseptic. Conclusion: According to the literature reviewed, many plants and their chemical compounds have antifungal action. Scientific studies prove the effectiveness of essential oils, considered an herbal medicine and its advantages in relation to allopathic medicines used in Dentistry and are considered promising agents for the development of new bioproducts applicable in the clinical routine.
Engineering Controls in Pesticide Application Technology to Help Reduce Exposure and Risk Levels in Spraying
Authors:   RB Field Sdn Bhd, Nathan L S
Published: April 2024

The heavy reliance on PPE as a safety control factor for workers involved in pesticide operations is well documented. Employers have not fully explored engineering and other controls before settling on PPE as a control factor. The OSH Act clearly says the need to use PPE “as a last resort”, however if no thoughts are given to engineering controls on spraying equipment and doing a risk assessment, the exposure to these risks are even much greater. Knapsack sprayers made with simple modifications and change in accessories like nozzles and calibrator Cf valves can improve safety tremendously. This paper will identify the approach by Malaysian manufacturers and distributors of spray applicators to design engineering safety considerations into spray technology in order to ensure the spray equipment complies with the safety requirements of OSH Act 1994 for two widely used handheld sprayers. Keywords: Improvements, engineering controls, safety, conventional knapsack sprayer (CKS), control droplet applicators (CDA), personal protective equipments (PPE).
Validation of a Time and Cost Saving Indirect Method of Oil Estimation from Oil Palm Mesocarp by Using Large-sized Soxhlet Apparatus
Authors:   National Research Centre for Oil Palm, Mandal P K , V Gayathridevi
Published: April 2024

Estimation of oil in the oil palm mesocarp is a very important process for evaluation of individual palms, which determines the actual oil yielding capacity. In the case of oil palm, each palm needs to be evaluated and hence, thousands of mesocarp samples are subjected to oil extraction every year. Usual procedure of oil estimation is by directly weighing the extracted oil. Each mesocarp sample is put in a thimble and oil is extracted in a Soxhlet apparatus by using petroleum ether as a solvent for 14 hours at 60-80OC followed by evaporation of the solvent and estimation of oil. Only one sample is extracted in each Soxhlet and hence, time and solvent requirement are very high. In the present study, a known amount of oil palm mesocarp was put inside a pouch of Whatman No.3 filter paper and several pouches were put in one big- sized Soxhlet apparatus for oil extraction. Subsequently, oil content was measured from the difference in weight of the pouch, before and after extraction of oil. Oil content from each dry mesocarp sample was estimated following both the methods. No significant difference in percentage oil extraction was observed, even at 1 per cent probability level, between the two methods. In the new method, a large-sized extractor of 2-litre capacity could extract a minimum of 50 samples at a time and thereby considerably reduced time taken by the conventional method. Moreover, since the mixture of oil from different samples collected with the solvent at the flask needed no attention, the solvent could be recovered by distillation and be reused. Keywords: Oil estimation, oil palm, mesocarp oil, indirect method.

Meghadrigedda reservoir is located in the Gajuwaka municipality of Visakhapatam district in Andhra Pradesh, India. The research was conducted at six distinct sites in the reservoir catchment region from April 2023 to March 2024, throughout pre-monsoon, monsoon, and post-monsoon periods. The current analysis indicated the presence of 52 weed species belonging to twenty orders, 33 families, and four classes. The present investigation compiled a list of hydrophytes, including their class, order, family, genus, species, and common name. The mentioned species under free floating, submerged species, and emergent weeds were found mostly around the mouths of the reservoir's main tributaries, in shallow areas with depths of about 7 feet. Among the 21 orders of aquatic weeds recorded, emergent weeds accounted for 52.38% (11 species), followed by submerged weeds 42.85% (09) and free floating weeds 21.81%. In 30 families, emergent weeds accounted for the most (66.66%), followed by submerged weeds (30.00%) and free floating weeds (20.00%). Emergent weeds dominate with 36 species, accounting for 69.23% of the total species, followed by submerged weeds with 10 (19.23%) and free floating weeds with 6 (11.53%). According to the IUCN (2014), there are 52 different species of hydrophytes. The status of these 42 aquatic weed species is least worried; 9 are not evaluated (NE), and one species is vulnerable (VU).

Successful Treatment Of A Chronic Venous Leg Ulcer Using The VenaSeal Closure System
Authors: Shlimun Maryana , Summers deLuca Leslie , Kayssi Ahmed
Published: April 2024

The VenaSeal procedure is a minimally-invasive intervention for the treatment of lower extremity superficial venous insufficiency. The VenaSeal closure system uses a medical-grade cyanoacrylate glue to seal incompetent veins. This adhesive collapses the vein walls, preventing blood flow in the treated incompetent superficial veins and forcing blood to travel in the deep venous circulation. This results in the relief of lower extremity superficial venous congestion and improvement in the side effects of venous insufficiency such as swelling, achiness, symptomatic varicosities, and venous ulcers. In this report, we describe a case of a 62-year-old man who underwent successful VenaSeal therapy of the great saphenous vein (GSV) for treatment of a venous leg ulcer (VLU).

Evangelische Vielfalt
Authors: Burkhardt Friedemann
Published: April 2024

Wer sich aufmacht, die religiöse Pluralisierung innerhalb des Protestantismus zu erkunden, wird zuallererst auf einen signifikanten Unterschied zum Katholizismus stoßen: Während dieser nur eine geringe konfessionelle Pluralisierung aufweist, zergliedert sich der Protestantismus weltweit in zehntausende Denominationen und kirchliche Partikulargemeinschaften, von denen die Mehrzahl nicht einer kontinentaleuropäischen Erscheinungsform zuzuordnen ist. Diese Vielfalt kennzeichnet den Protestantismus seit seinen Anfängen. Sie führte zur Ausbildung zahlreicher Denominationen, Freikirchen und Sondergruppen in theologischer, religiöser und ethischer Eigenart (Lutheraner, Reformierte, Täufer, Anglikaner oder Baptisten). Kolonialisierung, Mission und Migration sowie Erneuerungs- und Reformbewegungen wie der Pietismus, der Methodismus, die Heiligungsbewegung, die Pfingstkirchenbewegung und die evangelikale Bewegung trugen und tragen zur weltweiten Ausbreitung des Protestantismus bei. In der Gegenwart erweisen sich die globalen Migrationsdynamiken als der Hauptmotor religiöser Pluralisierung im Protestantismus.

Montessori Comes to America
Authors: Povell Phyllis
Published: April 2024

What role did women's leadership play in the introduction and revival of the Montessori Method in America? Phyllis Povell explores this question through the contributions of Maria Montessori and Nancy McCormick Rambusch, who brought the Montessori Method to the American educational scene. Introduced to the U. S. in the early 20th century by Montessori herself, the Method lapsed into oblivion after WWI. Thanks to Rambusch, it was reborn after the launching of Sputnik. In Montessori Comes to America, Povell traces the evolution of women's leadership and its influence on the Montessori Method's development. She includes insights from her own formative years, showing how childhood, education and career all shape women into leaders. New research not only illuminates the unique roles of two historic early childhood educators, but also updates the historical record and reveals the human dimension behind one of the most colorful chapters in American educational development.
Role models in HEI language learning
Authors: Sieglová Dagmar
Published: April 2024

People interact as part of social encounters within varied educational, professional, or free time contexts. These interactions breed numerous opportunities to meet people who become an important source of inspiration, motivation, and learning. This text explores critical incidents as an effective means of capturing these interactions for future reflection in the learning process in the context of HEIs’ language education. Critical incidents are vivid memorable life events that have significance for a person concerned.  Retold or rewritten in the form of narratives, they have enjoyed wide application in a range of disciplines from medicine, nursing to education as well-established, tested methodologies. This paper introduces the use of the Critical Incident Cycle (CIC) in the context of a Master’s degree course in Business English at Škoda Auto University (SAU) as a tool for enhancing students’ reflection on their learning experience so as to consolidate their language proficiencies and learning.
From the critical incident narratives collected, role models emerged as one of the dominant factors influencing the students’ learning and personal growth. This study provides empirical evidence of how the role models in these cases contribute to the formation of young people’s ideals, behaviors, and actions vis-à-vis self-development, language and communication skills set, and life-long learning. This paper argues that CIC provides a methodologically robust means for learners to actively enhance their learning outcomes through critical self-reflection of key aspects of their individual learning process.

Published: April 2024

The conglomerates and sandstones on the castle hill of Starý Jičín Castle, assigned by previous authors to units of different age and tectonic position, were studied from the point of view of petrography and sedimentology in connection with detailed geological survey of the area. Thick-bedded conglomerates are characterized by sharp bases, massive or normal gradation and, in places, by imbrication of coarse clasts. They are product of high-density turbidite currents, debris flow, alternatively some layers may by products of hybrid sediment gravity flow deposits. The clastic component of the conglomerates is highly dominated by Štramberk-type limestones. Clasts of dolomitized limestones, Těšín-type detrital limestones and calcareous sandstones, and altered trachyte occur very rarely. Medium- and coarse-grained calcareous sandstones contain abundant lithoclasts and a relatively small proportion of quartz grains (20–30 %). A comparison with the conglomerate and sandstone of the Palkovice Formation from Kozlovice and Myslík showed considerable similarity. The sediments of both areas range within the upper Turonian–middle Coniacian interval based on previous micropalaeontological data. The conglomerates from Starý Jičín represent the proximal facies of the submarine fan in the lower slope (Kelč Facies Succession of the Silesian Unit), while the gravity flow deposits of the Palkovice Formation represent the more distal facies of the middle part of the submarine fan in continental rise (Baška Facies Succession). Based on sedimentological features, conglomerates from Starý Jičín can be classified as high-density turbidites, debris flow or hybrid sediment gravity flow deposits deposited in the upper part of a submarine fan. High-density and classical turbidites intercalated with claystone interlayers occurs in the Palkovice Formation of the Baška Facies Succession. Such an idea is in accordance with current knowledge on submarine fan architecture and with the assumed morphology of the former Silesian Basin.
Registrace seismických jevů stanicí VRAC v letech 2011 až 2022 v porovnání s globální seismicitou
Authors: Havíř Josef
Published: April 2024

Širokopásmová seismická stanice VRAC (Vranov u Brna), provozovaná ÚFZ (Ústav fyziky Země, Masarykova Univerzita), je jednou z certifikovaných stanic IMS CTBTO (International Monitoring System of the Comprehensive Nuclear-Test-Ban Treaty Organization). Proto je velmi důležitá její schopnost zaznamenávat vzdálené seismické jevy. Tento článek se pokouší ukázat, pro jaké seismicky aktivní regiony může být využití stanice VRAC v rámci monitorování globální seismické aktivity výhodné. Za tímto účelem byla porovnána distribuce jevů registrovaných stanicí VRAC v letech 2011 až 2022 s celkovým rozložením projevů globální seismicity sledovaným na základě REB bulletinů (Reviewed Event Bulletin) CTBTO.
V letech 2011 až 2022 zaznamenala stanice VRAC 81110 seismických jevů, pro 60120 jevů je známa lokace (vypočtená v datovém centru ÚFZ anebo převzatá od jiných seismologických institucí). V případě 54314 z nich je epicentrální vzdálenost od stanice VRAC větší než 3°. Během stejného období lokalizovala IMS 440787 seismických jevů zařazených do REB bulletinů, data stanice VRAC byla využita při zpracování 21453 z těchto otřesů.
Nižší schopnost detekce seismických jevů stanicí VRAC byla pozorována nejen v případě regionů, vůči nimž se stanice VRAC nachází v zóně seismického stínu, ale také v regionech ve vzdálenostech 90° až 103° od stanice. Znamená to méně registrací jevů ze seismicky aktivních regionů Sumatry, Filipín a Střední Ameriky. Horši detekční schopnost vůči jevům ze vzdáleností 90° až 103° se očekávala, nikoli však v takové míře.
Naopak v důsledku kaustiky PKP vln je u stanice VRAC zjevný výrazně vyšší počet záznamů, a to i středně silných a slabých seismických jevů. Stanice VRAC tak dobře registruje otřesy z jižní části příkopu Nových Hebrid a z regionu Samoa.

Several ponds were built in the vicinity of the city of Zábřeh (Czech Republic) during the 15th century, all of which disappeared over time, leaving only one (Oborník) that survived to the present day. Currently, the only proof of the existence of these ponds in the landscape are the dams, preserved in varying degrees of quality. Another potential proof of the presence of ponds is pond sediment, the existence and extent of which are the subject of this text. The abandoned Leštinský pond, located to the east of Zábřeh, was chosen for this research. This pond was only captured on the maps from the 1st military mapping, it is no longer depicted on newer maps. Its presence is indicated by a partially preserved dam, which is not very distinct in the landscape but is visible in Lidar images. The pond sediments were investigated through a combination of geological survey (shallow boreholes) and geophysical prospecting (electrical resistivity tomography and ground penetrating radar). A total of 5 drill cores were taken on which magnetic susceptibility, grain size, geochemical composition and spectral reflectance were measured. Four facies were identified based on the lithology and the used analyses. These facies are interpreted as a recent soil (facie P1), pond sediment (facie R) and buried alluvial soil developed on fluvial sediments (facie P2) and coarse-grained sands (facie F). The data from geophysical survey correlates with boreholes lithology and extends this information spacially. Above all, ground penetrating radar (GPR) of facie RF3, interpreted as the base of pond sediments, can be easily observed in GPR profiles. The obtained results provide information about the presence and thickness of the pond sediment. Pond sediment was captured in boreholes at thickness ranging from 12 to 38 cm, with no internal pond sediment stratigraphy being observed. The probable reason for such a limited sediment thickness could be the initially shallow depth of the pond or the pond’s summering process (“letnění”), during which no water was present in the pond and the removal of the pond sediment occurred in regular cycles.

Fluvial archives are a rich source of information about the environmental impact of the local industry in the past. This research is focused on Holocene fluvial sediments that were excavated in the area of Křenová Street in Brno, Czech Republic. The area was researched during the rescue archaeological excavations, which unearthed the defunct Svitava river channel and its banks together with wooden constructions and archaeological artifacts from the 13th to the 16th century. Three profiles were documented and lithostratigraphically described. Samples for the palaeoecological and chemical analyses and granulometry were taken from the excavated trench S11. The finding of the rivers´ point bar and the shape of the riverbed allowed us to determine that the river was meandering. Analysed pollen profile of the medieval riverbed shows species-rich vegetation in close proximity of the medieval town and progressing urbanization. Results from chemical analyses shows that the area was not significantly polluted. The source of most of the probable contamination were surrounding sumps, as is indicated by slightly elevated concentrations of phosphorus in the sediments.

Hydrogeological area 4232 Ústí syncline in the drainage basin of the Svitava river is producing very significant amounts of underground water. This water has been used as drinking water since 1914 for the Brno agglomeration. Two hydrogeological structures are exploited: aquifer C (Jizera formation) and aquifer B (Bílá hora formation). The Ústí syncline represents an asymmetrical graben, the deepest part of which is delineated by the Semanín and Svitava faults. The underground water of both structures is replenished by rainfall in the areas where they crop-out, namely in the eastern flank of the whole syncline. Systematical monitoring of the quality of the underground water has been running in the area for a very long time. It comprises mainly monitoring of the water quality in the individual production areas and monitoring of wells of the Czech Hydrometeorological Institute. Evaluation of all these data showed, that the whole area of the Ústí syncline, but especially the aquifer C, is threatened by areal pollution by nitrate compounds and locally by pesticide metabolites. Nitrate content reach up to 40 mg/l, which is the limit concentration set by the regulation 252/2004 Sb. Pesticides locally exceed the limit concentration. This shows, that the most dangerous compounds for the underground water as potential contaminants are clearly compounds closely connected with agriculture. The introduction of potential contaminants is of course controlled by the hydrogeological properties of rocks, i.e. whether it is a reservoir rock or a sealing rock. Sandstones of the aquifer C are separated by a layer of marl, sometimes called the Ca/Cb aquiclude. However, in the near-surface zone and in outcrops, this marl is heavily fractured and is very permeable. The Ústí syncline is also known for several pseudo-karst caves. Moreover, deeper pseudo-karst caverns were penetrated by boreholes by accident during the exploration of the Semanín fault zone. This karst permeability enables rapid spreading of infiltrating compounds including all possible pollutants. Based on tritium activity, freons and SF6 measurements, the mean delay times of the underground water in the Ústí syncline is estimated to be the first tens of years. One cannot presume any natural attenuation of very stable pesticides metabolites, just dilution. Based on this, there is a very real risk, that with increasing share of underground water younger than 2010, which has much higher concentration of pollutants, the concentration of these compounds will increase in exploited underground water.
NEW FEATURES IN SOFTWARE OCFIT

Published: April 2024

Software OCFit is designed for fitting O-C diagrams of eclipsing binaries and transiting exoplanets by standard analytical models (e.g. light-time effect or apsidal motion). The program is written in the modern language Python. A very intuitive graphic user interface is also a part of this software. Moreover, OCFit could be used as a Python package in your own code. Its development started in 2015. GUI was published three years later. Here, we present changes and the newly implemented features in this software since its publishing in 2018 (mainly during the year 2022).
