Published: December 2023

Discutir conceitos no ensino de biologia torna-se fundamental para compreensão do conteúdo, os livros didáticos são muitas vezes o único recurso disponível aos alunos sendo importante para o processo de ensino e aprendizagem, o conceito de especiação é muito discutido no ensino de biologia, tanto no ensino médio quanto no ensino superior, verificar como estar inseridos esses conceitos de especiação e os tipos de especiação nos livros didáticos de biologia é fundamental para compreensão e aquisição do conteúdo em sala de aula. O objetivo deste artigo consiste em verificar como o conceito de especiação é abordado em dois livros didáticos do ensino médio e dois livros didáticos do ensino superior, ambos de biologia analisando suas diferenças e semelhanças. Trata-se de uma pesquisa qualitativa em que foi realizada uma revisão da literatura segundo Gil (2008), para a análise dos dados segundo Bardin (1977) verificou-se as diferenças e semelhanças e como cada autor aborda o conceito de especiação em seus livros e o conceito dos tipos de especiação. Os quatro livros abordam o conceito de especiação e dos tipos de especiação, apenas o livro da autora Mendonça (2016) não apresenta o conceito dos tipos de especiação e apenas o livro do autor Ridley (2016) apresenta o conceito de especiação parapátrica. O conceito de especiação difere de autor para autor, porém, eles são muito semelhantes, assim como o conceito de tipos de especiação, os livros didáticos são uma ferramenta importante para a compreensão do conteúdo, principalmente para o conteúdo de especiação, a análise dos conceitos nos livros, nos levou a dimensão de como a aprendizagem pode ser diversificada e distinta e isso depende de como cada autor aborda seus conteúdos e usam suas linguagens, porém quanto mais autores mais diversificado torna-se o conteúdo e sem dúvida melhora a compreensão e aquisição de conhecimento por parte dos leitores.

BACKGROUND: As physical inactivity and poor sleep quality may impose additional risk for cancer recurrence and overall mortality in postmenopausal breast cancer (PMBC) survivors, it is important to gain insight into the effect of the COVID-19 pandemic on their physical activity (PA) and sleep level. OBJECTIVE: This study aimed to assess the course of their physical activity (PA) and sleep throughout governmental measures against COVID-19 during 12 months of the COVID-19 pandemic. METHODS: PMBC survivors (n = 96) wore an ActiGraph wGT3X-BT for seven consecutive days at 12 and 18 months after diagnosis and additional measurements were taken after onset of the second (partial) COVID-19 lockdown. Longitudinal data was categorized into four timepoints: before onset of COVID-19 (T1), during the initial lockdown (T2), in between initial and second lockdown (T3), and during the second lockdown (T4). General linear mixed effects models assessed differences in moderate-to-vigorous physical activity (MVPA) per day, total minutes of PA per day, average acceleration, intensity gradient, sleep efficiency, and sleep duration over time. RESULTS: Levels of MVPA per day before COVID-19 were low (Median = 20.9 min/day (IQR = 10.8;36.2)), and time spent physically active was most often in light intensity, which remained stable throughout the pandemic. Sleep duration (Median = 442.8 min/night (IQR = 418.3;478.0)) and efficiency (85.9% (IQR = 79.6;88.4)) was sufficient before COVID-19 and showed stability over time. CONCLUSIONS: Low levels of PA with mostly light intensity, and adequate sleep efficiency and duration were observed before COVID in PMBC survivors. This was not further affected by COVID-19 governmental measures.

Published: December 2023

Thus, in laboratory conditions, experimental studies of the bearing capacity and crack resistance of a serial PAG plate with additional steel fiber reinforcement in the amount of 1% were carried out. In accordance with the regulatory documents in force in Ukraine, one of two possible load schemes was considered ― when loaded by a concentrated force applied to the cantilever part of the slab. The plate was tested on a specially made stand consisting of four support racks connected in pairs by beams on which the plate rested. The load was applied across the width of the slab in steps of 0.04 from the destructive load, in two concentrated vertical strips. Each level of load ended with a five-minute exposure, at the beginning and end of which the readings on the measuring devices were taken. All tests were carried out using two 30-ton jacks and a 50-ton dynamometer. The working principle of the jack consisted in the fact that its lower plane pressed on a two-level cross-beam system, and through it the load was distributed on the slab. In the process of testing the plates, the applied load, deflections and deformations were recorded. Clock-type indicators and protractors were used as measuring devices. The process of crack formation on the plate surfaces was observed with the help of a Brinell tube in the places of the largest crack opening.
As a result of the tests, the bearing capacity of the plate was 211.2 kN with a bending moment of 101.4 kNm. The load corresponding to the beginning of crack formation is equal to 96.0 kN at a bending moment of 46.1 kNm. The maximum width of crack opening was 0.25 mm. According to the readings of the indicators, graphs of the dependence of the relative deformation on the load were constructed. Graphs of the dependence of deflections on the load, constructed from the data of two deflection gauges. Before the appearance of the first crack, the maximum deflection of the plate is 17.0% of the deflection recorded at the end of the tests.

The article examines the advantages of high-rise construction at significant transport and interchange nodes at the entrance to cities using the example of the analysis of the Urban Planning Concept for the Placement of High-rise Buildings and Structures in Kyiv, developed by the Ukrainian Academy of Architecture and Projects of Kyiv Architects. According to the concept developed under the leadership of the president of UAA V.G. Stolka, the placement of new high-rise dominants should be aimed first of all at creating a clear architectural and urban planning and volume-spatial composition of the main urban planning nodes at the intersection of city highways.
The method of forming the dominant composition of the buildings of the transport and transfer hub is considered, using the example of the environment of the metro station "Livoberezhna". Brovarsky Avenue is an important highway for entering and leaving Kyiv. Modern investors in Ukraine consider increasing the number of floors of buildings in order to rationally develop territories. In the urban planning aspect, high-rise compositions emphasize important planning nodes. The construction regularities of the volumetric-spatial composition of high-rise buildings are divided into types and the characteristics of each of them are given. The historical aspect of the formation of compositional ensembles is taken into account on the example of the Livoberezhna metro station in Kyiv. The regularities of the construction of the volumetric-spatial composition of high-rise buildings are divided by type: a single object; a high-rise complex with several tower-type buildings connected by horizontal volume-spatial parts; a building in a group of volumes of different shapes and heights, spatially connected and located at a certain distance from each other. The search for iconic compositional and artistic qualities of high-rise buildings and optimal functional and planning solutions requires architects to use and combine various planning techniques, one of which is the design of atriums in the structure of high-rise buildings in extended stylobates, etc. The historical analysis of one of the nodes showed how the relationship to the stylistic characteristics of architecture changes in connection with the development of certain stylistic currents in the world.

Bell pepper (Capsicum annum L.) is one of the most important vegetable crops in Pakistan. This crop is prone to many fungal diseases, such as Phytophthora blight, Fusarium wilt, Verticillium wilt, Powdery mildew, and Anthracnose. Among all of them, Fusarium wilt is the most devastating disease of bell pepper that is responsible for heavy yield reduction. This study is aimed to identify and manage Fusarium solani in bell pepper, in vitro as well as in pots experiment. For this purpose, sampling, isolation, purification, and morpho-molecular identification were performed. Molecular characterization of F. solani was achieved by using ITS primers. The results showed that the nucleotide sequence of these isolates showed 100% homology to Fusarium solani. In vitro management was done by the application of Trichoderma harzianum and synthetic fungicides (Thiophanate methyl, Mancozeb+Metalaxyl, Fosetyl aluminum, Difenoconazole, and Sulphur). Five concentrations (100 ppm, 200 ppm, 400 ppm, 800 ppm, and 1000 ppm) were employed using dual culture and food poisoning method, respectively. LSD was used in combination with four replications. Data was taken after 3, 5, 7, and 10 days. The results showed that T. harzianum inhibited F. solani growth up to 87.98% after 10 days. As compared to the biological treatment, Thiophanate methyl showed maximum inhibition (100%) after 3 days at 100 ppm. Later on, its efficacy at 100 ppm was reduced after 5, 7, and 10 days. The inhibition after 10 days was calculated to be 72.89%. At 200, 400, 800, and 1000 ppm, the percentage of inhibition was up to 100%. Furthermore, Mancozeb + Metalaxyl showed maximum inhibition (100%) after 3 days at 1000 ppm. Similarly, Fosetyl aluminum showed maximum inhibition (100%) after 3 days at 1000 ppm. Whereas, Difenoconazole showed maximum inhibition (100%) after 3 days at 800 ppm. Later on, the efficacy at 800 ppm was reduced after 7 and 10 days. The inhibition after 10 days was calculated to be 87.72%. At 1000 ppm, the percentage of inhibition was up to 100%. Finally, sulphur showed maximum inhibition 82.7% after 3 days at 1000 ppm. Later on, its efficacy at 1000 ppm was reduced after 5, 7, and 10 days. The inhibition after 10 days was calculated to be 62.62%.

Metal scrap waste mixed with oil cutting can reduce the quality of the oil cutting itself, so it cannot be used directly. Meanwhile, the waste that is mixed with oil cannot be processed directly such as recycling / remelting. Cutting oil as a cooling material for the cutting process, so from here the recycle of cutting oil is needed, so a tool/machine is needed to separate the waste from the oil cutting.
The research method used is design research which consists of planning machine elements and making machine designs. In the planning of machine elements, more emphasis is placed on the impler blade of the vacuum separator while the drawing uses Autodesk Inventor.
From the results of the design and design of the "vacuum separator" it is obtained that; the dimensions of the impeller are 20 mm in diameter, the impeller neck is 28 mm in diameter, the impeller eye and the inlet side are the same diameter 92 mm, the inlet side of the impeller has an angle of 16 °, the width of the bow is 18.85 mm, while the distance between the blades (𝑡1) is 48.17 mm, the diameter of the outgoing side of the results of the calculation is 230 mm, the angle of the outgoing side of the impeller is 25 ° and the wide side of the impeller is 7.5 mm, at the distance between the blades of the incoming side (𝑡2) 120.42 mm. So that from the design of the machine element, the number of impellers is obtained 6 blades, with the results analyzed with a safety factor of 15 Ul.

ObjectiveThis study aims to access the efficacy of the binasal speculum in endoscopic endonasal surgery by evaluating clinical outcomes and examining its utility through process-based performance measures in both surgeons and assistants.MethodsA total of 59 patients with lesions in sellar region who underwent endoscopic endonasal surgery with the binasal speculum between September 2020 and March 2023 were included in this study. We assessed the extent of resection and documented postoperative nasal condition. Both surgeons and assistants completed post-use surveys to exam the utility of the binasal speculum and provide an overall grading.ResultsGross total resection (GTR) was successfully achieved in 94.9% (56/59) of patients, with subtotal resection (STR) observed in 5.1% (4/59) of patients. Intraoperative cerebrospinal fluid (CSF) leakage occurred in 23.7% (14/59) of cases, and nasoseptal flap (NSF) reconstruction was required in 55.9% (33/59) of cases. The nasal airway patency rapidly recovered within 14 days in a significant majority of patients (94.9%, 56/59). Moreover, olfactory function was regained within three months postoperatively by 91.5% (54/59) of patients. The overall post-use survey mean score was 26.4. Specifically, surgeons had a mean score of 26.5, while assistants had a slightly lower mean score of 26.2. The mean overall grading for the binasal speculum was 3. Both surgeons and assistants provided a mean overall grading of 3.ConclusionThe binasal speculum provides nasal mucosa protection and reduces the risk of an endoscopic lens clouded by mucosa or blood. It plays a crucial role in accurate guidance and facilitates the swift delivery of surgical instruments, particularly in left-blinded nasal cavities. The binasal speculum reduces the learning curve, especially for endoscopic surgeons with limited experience, while enhancing collaboration and coordination between surgeons and assistants during surgery. Both surgeons and assistants rated the overall utility of the binasal speculum as “excellent.”

Published: December 2023

IntroductionBioassembly techniques for the application of scaffold-free tissue engineering approaches have evolved in recent years toward producing larger tissue equivalents that structurally and functionally mimic native tissues. This study aims to upscale a 3-dimensional bone in-vitro model through bioassembly of differentiated rat osteoblast (dROb) spheroids with the potential to develop and mature into a bone macrotissue.MethodsdROb spheroids in control and mineralization media at different seeding densities (1 × 104, 5 × 104, and 1 × 105 cells) were assessed for cell proliferation and viability by trypan blue staining, for necrotic core by hematoxylin and eosin staining, and for extracellular calcium by Alizarin red and Von Kossa staining. Then, a novel approach was developed to bioassemble dROb spheroids in pillar array supports using a customized bioassembly system. Pillar array supports were custom-designed and printed using Formlabs Clear Resin® by Formlabs Form2 printer. These supports were used as temporary frameworks for spheroid bioassembly until fusion occurred. Supports were then removed to allow scaffold-free growth and maturation of fused spheroids. Morphological and molecular analyses were performed to understand their structural and functional aspects.ResultsSpheroids of all seeding densities proliferated till day 14, and mineralization began with the cessation of proliferation. Necrotic core size increased over time with increased spheroid size. After the bioassembly of spheroids, the morphological assessment revealed the fusion of spheroids over time into a single macrotissue of more than 2.5 mm in size with mineral formation. Molecular assessment at different time points revealed osteogenic maturation based on the presence of osteocalcin, downregulation of Runx2 (p &lt; 0.001), and upregulated alkaline phosphatase (p &lt; 0.01).DiscussionWith the novel bioassembly approach used here, 3D bone macrotissues were successfully fabricated which mimicked physiological osteogenesis both morphologically and molecularly. This biofabrication approach has potential applications in bone tissue engineering, contributing to research related to osteoporosis and other recurrent bone ailments.
