Published: June 2024

Undergraduate students majoring in the life sciences benefit from experience with data analyses that connect mathematical calculations to the biological systems they are studying. Monitoring the optical density and cell number of Saccharomyces cerevisiae liquid cultures allows students to gain quantitative experience generating standard curves and trendlines that capture the relationship between optical density and cell concentration for a given S. cerevisiae strain. Data comparisons across multiple strains can yield insights into the biophysical properties of cells that drive light absorbance and scattering. In this Tips and Tools article, we share a laboratory module that allows students to experience cell biology tools, laboratory measurements, and data analysis to determine the mathematical relationship between optical density and cell concentration in liquid microbial cultures. This module could be integrated into undergraduate classes ranging from general biology to upper-level cell biology or microbiology and can be a starting point for more complex investigations of microbial growth.
Fitted Fv/Fm temperature response curves: applying lessons from plant ecophysiology to acute thermal stress experiments in coral holobionts.
Authors: Campo Kelly Johanna Gomez , Baums Iliana B.
Published: June 2024

Maximum photochemical efficiency, Fv/Fm, is the preferred metric for quantifying the loss of photosystem II (PSII) function in photosynthetic algal symbionts (Symbiodiniaceae) of reef-building corals exposed to heat-stress, particularly at the early stages of coral bleaching. Loss of PSII function can be quantified as the temperature at which a holobiont loses 50% of maximum photochemical efficiency (50% effective dose, or ED50) when exposed to a range of experimental temperatures. Here, we demonstrate that dose-response curves can be substantially more informative about a coral’s stress response by including ED5 (5% effective dose), ED95 (95% effective dose), and Decline Width (ED95–ED5) values in summary statistics. These parameters are commonly used in plant ecophysiology and can be extracted from fitted Fv/Fm temperature response curves. This suite of metrics provides a broader understanding of the loss of PSII function in acute thermal stress experiments in corals and could enhance comparability among coral and plant studies
On the unresolved conjecture for the algebraic transfers over the binary field
Authors: Phúc Đặng Võ
Published: June 2024

Let us consider the binary field $\mathbb Z/2.$ An important problem of algebraic topology is to determine the cohomology ${\rm Ext}_{\mathcal A}^{h, *}(\mathbb Z/2, \mathbb Z/2)$ of the Steenrod ring $\mathcal A.$ This remains open for all homological degrees $h\geq 6.$ The algebraic transfer of rank $h$, defined by W.M. Singer in [Math. Z. \textbf{202} (1989), 493-523], is a $\mathbb Z/2$-linear map that plays a crucial role in describing the Ext groups. The conjecture proposed by Singer himself, namely that the algebraic transfer is one-to-one, has only been verified for ranks $h<5$ and remains an open problem in general. The objective which drives the writing of this article is to study the behavior of the algebraic transfer for ranks $h\in \{6,\, 7,\, 8\}$ across various internal degrees. More precisely, we prove that the algebraic transfer is an isomorphism in certain bidegrees. A noteworthy aspect of our research is the rectification of the results outlined by M. Moetele and M.F. Mothebe in [East-West J. of Mathematics \textbf{18} (2016), 151-170]. This correction focuses on the $\mathcal A$-generators for the polynomial algebra $\mathbb Z/2[t_1, t_2, \ldots, t_h]$ in degree thirteen and the ranks $h$ mentioned above. As direct consequences, we are able to confirm the Singer conjecture for the algebraic transfer in the cases under consideration. Especially, we affirm that \textit{the decomposable element $h_6Ph_2 \in {\rm Ext}_{\mathcal A}^{6, 80}(\mathbb Z/2, \mathbb Z/2)$ does not reside within the image of the sixth algebraic transfer}. This event carries significance as it enables us to either strengthen or refute the Singer conjecture, which is relevant to the behavior of the algebraic transfer. Additionally, we also show that the indecomposable element $q\in {\rm Ext}_{\mathcal A}^{6, 38}(\mathbb Z/2, \mathbb Z/2)$ is not detected by the sixth algebraic transfer. \textit{Prior to this research, no other authors had delved into the Singer conjecture for these cases. The significant and remarkable advancement made in this paper regarding the investigation of Singer's conjecture for ranks $h,\, 6\leq h\leq 8,$ highlights a deeper understanding of the enigmatic nature of ${\rm Ext}_{\mathcal A}^{h, h+\bullet}(\mathbb Z/2, \mathbb Z/2)$}.
Keeping Pace with Wearables: A Living Umbrella Review of Systematic Reviews Evaluating the Accuracy of Consumer Wearable Technologies in Health Measurement
Authors: Doherty Cailbhe , Baldwin Maximus , Argent Rob , Keogh Alison , Caulfield Brian
Published: June 2024

Background: Consumer wearable technologies have become ubiquitous, with clinical and non-clinical populations leveraging a variety of devices to quantify various aspects of health and wellness. However, the accuracy with which these devices measure biometric outcomes such as heart rate, sleep and physical activity remains unclear.Objective: To conduct a “living” (i.e., ongoing) evaluation of the accuracy of consumer wearable technologies in measuring various physiological outcomes.Methods: A systematic search of the literature was conducted in the following scientific databases: MEDLINE via PubMed, Embase, Cinahl, and SPORTDiscus via EBSCO. The inclusion criteria required systematic reviews or meta-analyses that evaluated the validation of consumer wearable devices against accepted reference standards. In addition to publication details, review protocol, device specifics, and a summary of the authors’ results, we extracted data on mean absolute percentage error (MAPE), pooled absolute bias, intraclass correlation coefficients (ICC), and mean absolute differences. Results: Of 904 identified studies through initial search, 24 systematic reviews met our inclusion criteria, which themselves included 249 non-duplicate validation studies of consumer wearable devices which included of 430,465 participants (43% female). Of the commercially available wearable devices released to date, approximately 11% have been validated for at least one biometric outcome. However, because a typical device can measure a multitude of biometric outcomes, the number of validation studies conducted represents just 3.5% of the total needed for a comprehensive evaluation of these devices. For heart rate, wearables showed a mean bias of ±3%. In arrhythmia detection, wearables exhibited a pooled sensitivity and specificity of 100% and 95%, respectively. For aerobic capacity, wearables significantly overestimated VO2max by ±15.24% during resting tests and ±9.83% during exercise tests. Physical activity intensity measurements had a mean absolute error ranging from 29-80%, depending on the intensity of the activity being undertaken. Wearables mostly underestimated step counts (mean absolute percentage errors ranging from -9% to 12%) and energy expenditure (mean bias = -3kcal per minute, or -3%, with error ranging from −21.27% to 14.76%). For blood oxygen saturation, wearables showed a mean absolute difference of up to 2.0%. Sleep measurement showed a tendency to overestimate total sleep time (mean absolute percentage error typically >10%).Conclusions: While consumer wearables show promise in health monitoring, a conclusive assessment of their accuracy is impeded by pervasive heterogeneity in research outcomes and methodologies. There is a need for standardised validation protocols and collaborative industry partnerships to enhance the reliability and practical applicability of wearable technology assessments.
Solving mystery with the Meissner state in La3Ni2O7-x
Authors: Talantsev Evgeny F.
Published: June 2024

Recently, zero resistance state in highly compressed La3Ni2O7-x has reported by Zhang et al (Nature Physics (2024), 10.1038/s41567-024-02515-y). However, all attempts of many research groups to detect the Meissner state in the La3Ni2O7- have been failed. To explain this puzzle, an exotic superconducting state (so-called, filamentary superconductivity) in the La3Ni2O7-x has proposed (Zhou et al, arXiv:2311.12361). Here, we extracted temperature dependent self-field critical current, Ic(sf,T), dataset from current-voltage curves reported by Zhang et al (Nature Physics (2024)). The analysis of the Ic(sf,T) reveals that the highly compressed La3Ni2O7- exhibits d-wave superconductivity with the gap-to-transition temperature ratio 2Δ(0)/(k_B T_c )=4.0±0.3, and a very large ground state London penetration depth, lambda(0, P=16.6 GPa) = 6.0 micron, and a very high Ginzburg-Landau parameter k(0, P=16.6 GPa) = 1500. This implies that the ground state lower critical field Bc1(0, P=16.6 GPa) = 34 microTesla is the same order as the Earth's magnetic field. Based on this, to detect the Meissner state in the La3Ni2O7-x represents a very challenging task. I can hypothesize that the magnetic flux trap effect recently proposed by Minkov et al (Nature Physics 19, 1293 (2023)) to eliminate the diamond anvil cell (DAC) background signal in experiments on magnetic properties of the superconducting hydrides can be also applied in studies of the La3Ni2O7-x superconductor.
The influence of recall direction on judgments of subjective temporal distance from the beginning of the Covid-19 pandemic lockdowns
Authors: Dantzler Connor Drake , Markman Keith
Published: June 2024

Introduction: In a series of 5 studies, Lam and Buehler found that first-year university students felt closer to a target event (the day they learned that they were accepted into university) when they recalled a stream of related events in a backward direction (a reverse-chronological order ending with the target event) than when they recalled those events in a forward direction (a forward-chronological order beginning with the target event).Methods: In a conceptual replication of their Study 2, we asked participants how close they felt to the first day that lockdowns were imposed in response to the Covid-19 pandemic in the U.S. (federally mandated on March 13, 2020) following either backward or forward recall of a stream of related events.Results: The results of the present study ran directly counter to those of Lam and Buehler: participants rated the first day of lockdowns as feeling closer following forward recall than following backward recall.Discussion: Potential explanations for this reversal of Lam and Buehler's effect are discussed that focus on the temporal distortions that people have been found to experience when they think about autobiographical events that occurred at the beginning of the pandemic.

Published: June 2024

Wildfires increasingly threaten California’s agricultural sector, posing serious risks to farming, ranching, and food systems. We conducted a survey of 505 California farmers and ranchers affected by wildfires between 2017 and 2023. Main findings show that wildfires’ impacts on producers are extensive and range from mild to catastrophic, with both short and long-term repercussions, regardless of their exposure level. Producers play a central role in community emergency wildfire risk response and management by reducing fuel loads, creating defensible space, and leveraging their fire management expertise for themselves and their neighbors. Many producers lack a robust financial safety net, particularly among vulnerable populations, pointing to the need to increase access to recovery resources including insurance and disaster assistance programs. We find an urgent need for policy reforms, improved support, targeted extension programs, and integrated coordination mechanisms. Producers are our overlooked allies in building widespread wildfire resilience. Enhanced collaborative efforts among producers, fire professionals, and agricultural support organizations are thus imperative to co-create and implement strategies that ensure the long-term sustainability and economic viability of California’s agricultural communities.
The Promise of Apps-Based Reading Comprehension for Students with Autism Spectrum Disorder: Implications for Practice
Authors: Thalia Nita
Published: June 2024

Literacy skills are essential for learners’ development and future success. This literature review explored using assistive technology applications (apps) for literacy instruction of students with autism spectrum disorder (ASD), specifically reading comprehension. The primary aim was to identify strategies for implementing app-based literacy instruction to support students with ASD in school and home settings. Studies focusing on reading comprehension skill development were reviewed. The results indicated apps are an effective educational tool for promoting reading comprehension skills of students with ASD. Further, parents and teachers have positive attitudes toward app-based instruction. Implications for practice such as planning interventions, choosing appropriate apps, providing professional development, and establishing school-home collaboration are presented. Successful case examples of applying effective apps within classroom settings are also discussed. While promising, a significant literature gap was identified, suggesting future research should examine integrating apps into applied behavior analysis interventions and replicate past studies.
Prinsip dan Kode Etik Dalam Bisnis
Authors: Alaslan Amtai
Published: June 2024

Dalam berbagai diskursus tentang konsep bisnis, sering dibicarakan tentang adanya pergesaran dalam etika bisnis yang keliatanya semakin merosot. Merosotnya rasa solidaritas, tanggung jawab sosial (sosial responsibility), praktek ketidak jujuran diantara pelaku bisnis serta berbagai praktek Fraud (kecurangan) yang sengaja dilakukan untuk kepentingan pribadi dan kelompok merupakan tindakan-tindakan yang mengahancurkan tata nilai etika bisnis itu sendiri. Permasalahanya adalah tidak adanya hukuman yang tegas terhadap pelangaran etika tersebut karena nilai etikanya hanya termanifestasi dalam hati nurani seseorang. Etika itu mempunyai kendali internal dalam hati, berbeda dengan hukum yang mempunyai unsur paksaan yang bersifat ekstern. Penegakan hukum saat ini harus jauh lebih kuat yang diharapkan sebagai salah satu driven force dari masyarakat madani (civil society) untuk dapat menjalankan bisnisnya dengan baik. Oleh karena itu bisnis tidak pantas disebit good business, kalau penegakan hukum dan etika serta moralitasnya tidak baik juga.

Authors: Alyaquby Ali , Asal Kzar Ahmed
Published: June 2024

The change detection in urban and surrounding areas, such as vegetation and bare, is a significant achievement for sustainable development, especially nowadays. The research conducted a supervisor classification of two images representing two time periods (1973 and 2023) using the method of land cover and land use (LCLU) using the ArcGIS 10.8.2 program. The classified pixels were converted into digital data to compare using the land cover method and land use change (LCLUG). The results showed a significant expansion in the urban areas of Najaf and Kufa districts, 5.72 km2 to 134.95 km2, with a decrease in the area of green areas, 17.26 km2 to 15.16 km2, and the absence of water areas, in addition to the transformation of most of the barren areas to urban areas 215.64 km2 to 88.51 km2,  The study concluded that there was a significant decrease in the area of green areas in the study area and the absence of water bodies in urban areas, and these two indicators - along with the increase in urban areas - harm the environment of the region and the quality of environmental influences on the lives of the people who live in it. Which negatively affects its sustainable development plans.
Overseas Capital Streams and Economic Growth Nexus: Pragmatic Insights from Nepal
Authors: Dahal Arjun
Published: June 2024

The objective of the present research is to ascertain the impact of foreign capital inflows, including grants, loans, remittances, and income from tourism, on the economic growth of Nepal. This study utilizes secondary data acquired from several Nepalese economic surveys and World Bank reports. The data consists of 35 data points spanning from the fiscal years 1987/88 to 2021/22. The link between foreign capital inflows and GDP growth in Nepal is examined using fundamental statistical approaches like quantile regression, trace and Max-Eigen cointegration tests, and descriptive statistics. The results show that Nepal's grants, debt, foreign remittances, tourism earnings, and GDP growth co-integrate over the long term. Notably, 80.5 percent of Nepal's GDP growth fluctuation is accredited to foreign grants, loans, remittances, and tourism income. While foreign loans and grants are not statistically significant in and of themselves to measure GDP growth, foreign remittances and tourism income are. For every percentage increase in the median value of remittance and tourism income, the GDP grows by 0.251 and 0.816 percent, respectively. More revenue from tourism than from remittances goes towards Nepal's economic growth. Legislators can, therefore, enact suitable measures to encourage the expansion of the tourism industry

Authors: Neupane Ajay , Bhandari Udeshya , Khatiwada Homnath
Published: June 2024

Terai Sal (Shorea robusta C.F.Gaertn.) forest, characteristic forest of lowland of Nepal, faces direct and indirect impacts from various anthropogenic activities. The present work aimed to study and document the flowering plant diversity within differentially disturbed sites of Charali Sal forest. Additionally, we accessed the habitat condition, analyzed the invasion status and prioritize the threats faced by the plant communities and recommended ways to mitigate the prevalent threats. We employed purposive sampling technique to sample the forest areas and nested plot design for vegetation sampling. Thirty sample plots, each measuring 10 m × 10 m, were established on two differentially disturbed sites (disturbed and undisturbed) of Charali Sal forest. A total of 111 flowering plant species belonging to 39 families were documented in the sampling sites, with 90 total species (89 identified) in disturbed sites and 86 species (80 identified) in undisturbed sites. Although the disturbed sites contained higher number of flowering plants, the diversity indices (Simpson and Shannon-wiener’s) indicated higher diversity on undisturbed site. Disturbed site exhibited higher human encroachment and higher invasion of alien species compared to undisturbed site. Specific habitat management plans should be devised for the control and eradication of invasive species from the Charali Sal forest. We highly recommend to delimit a buffer zone all around the forest perimeter to regulate local access inside the forest. Collecting and harvesting various forest products should be restricted to the buffer zone, while the inner forest areas should be under careful and strict management. Implementing these strict managemental strategies would be challenging, but it is crucial for preserving the natural integrity of the forest.

Authors: Saud Sarmila Kumari , Aryal Bhagwan , Ranabhat Chhabilal
Published: June 2024

Any sex work involving the exchange of money or goods/gifts (i.e. commercial sexual activity) and prostitution in all forms and names are illegal in Nepal. Many issues and violence have been documented as a result of sexual labor in such areas, mainly against female sexual workers (FSWs). This study aimed to explore the lived experiences of violence and the related health issues among FSWs in Kathmandu. A descriptive phenomenological research design was followed where the participants provided their informational experience about violence. The nature of the information was qualitative and subjective, and based on the interpretivism paradigm. The study reveals that verbal aggressions, physical violence, sexual harassment, assault, and other forms of violence are the primary experiences faced by FSWs, along with health issues like STIs, Hepatitis, vaginal infections, backaches, stress, depression, and chronic fatigue. Lived experiences illustrate the opportunities and skills for earning a living via work that could be planned and executed at the federal, provincial, and local levels of government. Similarly, if someone wants to alter their employment or sex trade, rehabilitation is required. It is critical to put in place certain focused measures and policies to safeguard the safety, self-esteem, and financial stability of FSWs.

Published: June 2024

Understanding the nutritional content of food after processing is important for the food processing industry. Choosing the appropriate processing method allows users to retain healthy micronutrients. In fact, collecting nutrient information of food before and after processing poses many challenges due to biological changes and interactions of nutritional components. Currently, the approach is to collect data on each nutritional component before and after processing. Conventional machine learning models will then use this data to produce good prediction results but with limited stability. Therefore, we proposed to use a deep learning model to conduct training on a data set with 27 nutritional components that change through two processing processes, boil and fry, extracted from a standard reference data set of the United States. The results show accurate prediction and improve the stability by 8.6%.

In this study, three antibiotics, chloramphenicol (CAP), amoxicillin (AMX), and enrofloxacin (ENR), were simultaneously analysed for the first time using electrochemical sensors. The multilayer graphene electrode used in the sensor was directly and rapidly fabricated from graphite through a one-step chronoamperometry method. Scanning electron microscopy and cyclic voltammetry techniques revealed the multilayer-graphene nanostructure of the prepared electrode with a large electrochemically active surface area and good electrochemical activity. The electrode exhibited the best electrochemical oxidation signals corresponding to the three antibiotics when fabricated at a potential of 5 V for 20 s. Under optimised conditions, the sensor demonstrated excellent multi-analyte analysis capability, with clear separation and good linearity of the signals of the three antibiotics (R2>0.99) in relation to their concentrations. The sensor exhibited high accuracy and sensitivity with detection limits of 0.060, 0.381, and 0.109 μM for CAP, AMX, and ENR, respectively. The applicability of the sensor was demonstrated through acceptable recoveries of all three antibiotics when simultaneously analysed in a lake water sample.

Objective: Examine the clinical and subclinical characteristics and the rate of autoantibodies in systemic sclerosis (SSc) using Immunoblot technique (ANA 23 Profile). Research subjects and methods: Cross-sectional descriptive study of 57 patients diagnosed with SSc according to the 2013 American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) criteria and were tested for autoantibodies using the Immunoblot technique (ANA 23 Profile) at the National Hospital of Dermatology and Venereology. Results: Among 57 SSc patients, the female/male ratio was 5/1. The average age of disease onset was 49.3±13.3, with 57.9% of patients over the age of 50. Diffuse SSc was the most common (70%). Raynaud was the most common symptom (98.2%), followed by gastroesophageal reflux (86%), and pulmonary fibrosis (70.2%). Heart and kidney damage were less frequently observed, accounting for 15.8 and 5.3%, respectively. Positive rates of the three major antibodies in SSc included anti-Scl-70 antibody (63.2%), anti-centromere antibody (17.5%), and anti-RNA polymer III antibody (12.3%), respectively. Scl-70 autoantibodies were mainly found in diffuse skin types (91.7%) while CENP autoantibodies were mainly found in localised skin types (90%) with p<0.05. RNAP III antibodies were mainly found in diffuse skin types (85.7%), however, this difference was not statistically significant (p>0.05). Conclusion: The presence of Scl-70 was related to the diffuse skin types while the presence of CENP was related to localised skin types.

Purpose: Angiomyolipomas are usually diagnosed incidentally and are usually asymptomatic. Dysmorphic blood vessels in angiomyolipomas usually do not contain an internal elastic lamina, so bleeding risks are high. Particularly, lesions larger than 4 cm have a tendency to become symptomatic and can present with life-threatening retroperitoneal or urinary bleeding. Although intrarenal or perinephric bleeding is the usual complication of angiomyolipomas, a pseudoaneurysm appears unusual. In this case, we aimed to present a patient with pseudoaneurysm, an unusual complication of angiomyolipoma.
Case presentation: In this article, a patient who presented with complaints of left flank pain and hematuria and who underwent selective arterial embolization due to pseudoaneurysmatic angiomyolipoma in the left kidney is presented. The patient's angiography showed a large hypervascular mass filling the upper and middle segments of the left kidney. A pseudoaneurysmal filling originating from a subsegmental branch was observed in the mass. The patient underwent selective embolization. After 5 years of follow-up, the mass was observed to shrink.
Conclusions: Angiomyolipomas are benign tumors, but especially symptomatic masses larger than 4 cm and especially masses with aneurysms larger than 5 mm can cause life-threatening retroperitoneal hemorrhages. Coexistence of angiomyolipomas with pseudoaneurysm is rare, especially. Safe, effective and minimally invasive selective arterial embolization can be safely performed to prevent massive bleeding and rupture.
Análise da participação dos bioinsumos para controle biológico na agricultura orgânica brasileira
Authors:   , Sousa Jeremias Marques de
Published: June 2024

O presente estudo tem por objetivo analisar a participação dos bioinsumos para controle biológico na agricultura orgânica brasileira. A busca por sistemas de produção agrícola sustentáveis e por alimentação saudável tem mobilizado tecnologias, produtores, consumidores, investidores e agentes públicos. Nesse cenário a agricultura orgânica toma espaço e posiciona o Brasil como um dos principais países produtores e consumidores de produtos orgânicos da América Latina. A produção orgânica é caracterizada por práticas que envolvem conhecimento da agroecologia, o uso de insumos para a produção orgânica e processos de certificação e comercialização de produtos. Os bioinsumos para controle biológico são tecnologias em desenvolvimento capazes de reduzir o uso de agrotóxicos químicos e seus impactos na contaminação do solo, água, alimentos e produtores, na alta dos custos de produção e perda da biodiversidade. Dessa forma, a criação dos instrumentos contidos nas especificações de referência coloca o controle biológico como bioinsumo para a produção orgânica.
Interações intraguilda entre Amblydromalus limonicus (Garman & Mcgregor) (Acari: Phytoseiidae) e Orius insidiosus (Say) (Hemiptera: Anthocoridae) e controle biológico de pragas em pimentão no estado de São Paulo

Published: June 2024

O ácaro-rajado, Tetranychus urticae Koch (Acari: Tetranychidae), é um dos ácarospraga de maior importância para a agricultura em todo o mundo. Os tripes (Franklinilella sp.) (Thysanoptera: Thripidae) e as moscas-brancas, Bemisia tabaci (Genn.) (Hemiptera: Aleyrodidae), têm causados grandes prejuízos à agricultura, devido aos seus danos diretos às plantas e à transmissão de fitovírus. Esses três grupos de artrópodes são considerados pragas-chave para a cultura do pimentão no Brasil. O uso de ácaros predadores da espécie Amblydromalus limonicus (Garman & McGregor) (Acari: Phytoseiidae), em associação ou não com Orius insidiosus (Say) (Hemiptera: Anthocoridae), pode representar uma boa estratégia para o manejo dessas pragas, em diferentes cultivos agrícolas, no Brasil.
ELUCIDATING A FORMATIONAL ENVIRONMENT FOR PALEOPROTEROZOIC TOURMALINITES FROM THE CERRO COLORADO, TUSAS MOUNTAINS, NEW MEXICO
Authors:   , Barnard Michael
Published: June 2024

"Tourmalinites and their associated tourmalines record significant information on both the host rock and fluid compositions in which they grew. This information is utilized to evaluate tourmalines preserved within a section of Paleoproterozoic crust, in a region where outcrops are poorly exposed. Recently recognized Paleoproterozoic tourmalinites from the Cerro Colorado, Tusas Mountains, New Mexico, provides a new avenue to elucidate a formational environment for this locality. Field work, mineral chemistry, whole rock chemistry, and boron isotopic data were used to constrain the formational environment of the tourmalinites. Tourmalinites from the Cerro Colorado, Tusas Mountains, are structurally situated in a regional antiform and are hosted within a staurolite-garnet-biotite schistose host rock as highly deformed discontinuous and continuous stratabound layers. Tourmalinites contain the major assemblage tourmaline+quartz+plagioclase. Tourmaline is very fine grained with an average diameter of ≤10µm. Tourmaline compositions within the host rock and the tourmalinites are similar. Chemical analysis of tourmaline show little variation, with tourmalines classified as belonging to the alkali and hydroxyl groups. Both Mg-rich schorl and Fe-rich dravite species are present. The average formula is: (Na0.64□0.24Ca0.12)(Mg1.64Fe2+1.14Al0.13Ti0.09)Al6(BO3)3(Si5.91Al0.09)O18OH3(OH0.85F0.10O0.05). Minor chemical substitutions within tourmaline are given largely by the MgFe-1, with less contribution by FeAl-1, and (AlO)(Mg(OH))-1 exchange vectors. Tourmalinite trace element chemistry normalized to average continental crust are enriched in elements such as K, Sr, Ni, Sc, Cr, Zr, and Hf. Boron isotopic values for tourmaline within tourmalinites are consistent and range from -14.1 to -12.1 δ11B ±2‰. Comparison of tourmaline chemistry, field relations, and associations with other tourmalinite forming environments suggests that tourmalinites were formed within a metasomatic environment. Garnet-biotite-plagioclase-sillimanite geothermobarometers suggests that tourmalines crystallized between 550-600oC and 3-4 kbar. Minor chemical variations and the lack of zoning suggests that tourmaline crystallized during a single event from continentally sourced B-bearing fluids from as suggested by the negative δ11B values. Local metasediments could react to provide the necessary Al required for tourmaline formation. The occurrence of tourmalinites within the region also may have preserved a highly localized infiltration of a B-rich fluid during the Paleoproterozoic."

Published: June 2024

O tema solos, no Ensino Fundamental, geralmente é relegado a segundo plano no currículo de Ciências devido, principalmente, à falta de metodologia dos professores. O objetivo do trabalho foi utilizar a horta escolar como ferramenta prática para Educação Ambiental com ênfase em solos. As atividades foram desenvolvidas em três etapas: palestra para alunos do 5º ano, dinâmica de representação do solo e seus componentes e atividade prática na horta. Foi realizada pesquisa de cunho qualitativo, por meio de observação assistemática. Observou-se aumento da participação dos alunos, uma vez que o assunto de sala de aula passou a ter significado, tornou-se realidade para os alunos. A dinâmica foi um importante recurso para a fixação e avaliação do processo ensino-aprendizagem. A atividade prática na horta mostrou-se como excelente recurso complementar à teoria mostrando-se como importante ferramenta para uma aprendizagem significativa no ensino de solos.
