ABSTRACT
Formal and non-formal education are two concepts that describe different types of learning and educational processes. Both are important in the development of skills and knowledge in people, but they differ in their structure, objectives and context of application. In Mexico, both modalities have their distinctive characteristics and play important roles in the educational and social development of the population. The article reflects on formal and non-formal education in Mexico. Formal education provides a solid foundation of knowledge and skills essential to society, while non-formal education provides additional lifelong learning opportunities and allows for the development of specific skills beyond the traditional education system. Importantly, each type of education can complement and enrich a person's global learning, providing opportunities for personal and professional growth.

Published: March 2024

En esta investigación se busca en un primer momento el diagnóstico de comprensión lectora de los alumnos al ingresar al primer semestre de bachillerato, y en un segundo momento implementar estrategias didácticas a partir de su estilo de aprendizaje que coadyuven a elevar su nivel de comprensión lectora. La comprensión del texto no es inmediata, si no que se realiza un constructo a partir de las representaciones que el mismo vaya realizado. Por lo que se debe de comprender como los estudiantes procesan cognitivamente el lenguaje, para después apropiárselo. Entonces se puede decir que existen 2 momentos dentro de este proceso: La primera que es la lectura del texto y la segunda la comprensión de lo leído. Por lo tanto, se puede afirmar que el texto por sí solo tiene una estructura lógica que lo ayuda a ser comprensible.

ABSTRACT
This research seeks, first, to diagnose the students' reading comprehension when they enter the first semester of high school, and secondly, to implement teaching strategies based on their learning style that help raise their level of reading comprehension. The understanding of the text is not immediate, but a construct is made from the representations that it is made. Therefore, it is necessary to understand how students cognitively process language, and then appropriate it. So it can be said that there are 2 moments within this process: The first is the reading of the text and the second is the understanding of what has been read. Therefore, it can be stated that the text itself has a logical structure that helps it be understandable.

Construction of a predictive model for bone metastasis from first primary lung adenocarcinoma within 3 cm based on machine learning algorithm: a retrospective study
Authors: Zhang Yu , Xiao Lixia , LYu Lan , Zhang Liwei 
Published: March 2024

Background
Adenocarcinoma, the most prevalent histological subtype of non-small cell lung cancer, is associated with a significantly higher likelihood of bone metastasis compared to other subtypes. The presence of bone metastasis has a profound adverse impact on patient prognosis. However, to date, there is a lack of accurate bone metastasis prediction models. As a result, this study aims to employ machine learning algorithms for predicting the risk of bone metastasis in patients.

Method
We collected a dataset comprising 19,454 cases of solitary, primary lung adenocarcinoma with pulmonary nodules measuring less than 3 cm. These cases were diagnosed between 2010 and 2015 and were sourced from the Surveillance, Epidemiology, and End Results (SEER) database. Utilizing clinical feature indicators, we developed predictive models using seven machine learning algorithms, namely extreme gradient boosting (XGBoost), logistic regression (LR), light gradient boosting machine (LightGBM), Adaptive Boosting (AdaBoost), Gaussian Naive Bayes (GNB), multilayer perceptron (MLP) and support vector machine (SVM).

Results
The results demonstrated that XGBoost exhibited superior performance among the four algorithms (training set: AUC: 0.913; test set: AUC: 0.853). Furthermore, for convenient application, we created an online scoring system accessible at the following URL: https://www.xsmartanalysis.com/model/predict/?mid=731symbol=7Fr16wX56AR9Mk233917, which is based on the highest performing model.

Conclusion
XGBoost proves to be an effective algorithm for predicting the occurrence of bone metastasis in patients with solitary, primary lung adenocarcinoma featuring pulmonary nodules below 3 cm in size. Moreover, its robust clinical applicability enhances its potential utility.

Aim: The nutrient content of current fertilizer recommendations is unbalanced and is based on a very general and blanket recommendation for all soil and crop types, and their economic benefit is low. Therefore, this study was initiated to validate the recommendations regarding blended fertilizers applied to the soil and to identify the best fertilizer dose that ensures optimal yield and maximum economic return.
Study Hypotheses: significance effect of blended NPKSZnB fertilizer on onion yield and yield components.
Study Design: The experiment was designed using a randomized complete block design with three replications and seven treatments.
Place and Duration of the study: The field experiment was conducted in the off-season of 2018 and 2019 in Tahtay Koraro (two farmers), and Laelay adyabo (two farmers) districts of in northern Ethiopia.
Methodology: Seven treatments with NPKSZnB fertilizer rates (25, 50, 100, 150, 200, 250 and 300 kg·ha-1) were tested under irrigation conditions. Thus, for each plot nitrogen from Urea was applied at a rate of 150 kg ha-1. Surface soil samples were collected before planting onion harvesting at a depth of 0-20 cm to analyze selected soil chemical properties such as pH, extractable electric conductivity (ECe), cation exchange capacity (CEC), total nitrogen (TN), available P and exchangeable bases (K, Mg, Ca, and Na).
Results: The application of different doses of NPKSZnB under irrigation conditions had a statistically significant (P < 0.05) impact on onion phenology, yield and yield components. The highest average onion yield (10,329 and 19,196 kg ha-1) was obtained after applying compound fertilizer doses of 200 and 250 kg ha-1 in Teahtay Koraro and Laelay Adyabo districts, respectively. However, the use of NPKSZnB fertilizer at a dose of 100 and 50 kg ha-1 for onion cultivation under irrigated conditions in T/koraro and L/adyabo districts was found to be economically viable. Thus, growers in both districts should use NPKSZnB compound fertilizer at these rates for onion production and productivity.
Conclusion: Therefore, farmers in both districts should use NPKSZnB compound fertilizer at these rates for optimum onion production.

Published: December 2006

AbstractBackgroundThis study estimates the annual cost of alcohol‐related injuries to employers in 1998–2000.MethodsIncidence was estimated with occupational injury data, motor vehicle crash data and health care data for 1998–2000. Employer costs were estimated from federal estimates of injury costs by source of payment using data on the percentage of varied payment streams (e.g., health insurance, sick leave) paid by employers.ResultsThe annual employer cost of alcohol‐related injuries to employees and their dependents exceed $28.6 billion. Out of this, $13.2 billion comes from job‐related, alcohol‐involved injuries. The annual employer cost of motor vehicle crashes in which at least one driver was alcohol‐impaired is over $9.2 billion. Out of this, only $3.4 billion comes from job‐related alcohol involvement.ConclusionSafety programs can reduce the fringe benefit bill without reducing the benefits offered to employees. Am. J. Ind.

Published: December 2006

AbstractObjectiveFrontotemporal dementia (FTD) is a neurodegenerative disease that erodes uniquely human aspects of social behavior and emotion. The illness features a characteristic pattern of early injury to anterior cingulate and frontoinsular cortex. These regions, though often considered ancient in phylogeny, are the exclusive homes to the von Economo neuron (VEN), a large bipolar projection neuron found only in great apes and humans. Despite progress toward understanding the genetic and molecular bases of FTD, no class of selectively vulnerable neurons has been identified.MethodsUsing unbiased stereology, we quantified anterior cingulate VENs and neighboring Layer 5 neurons in FTD (n = 7), Alzheimer's disease (n = 5), and age‐matched nonneurological control subjects (n = 7). Neuronal morphology and immunohistochemical staining patterns provided further information about VEN susceptibility.ResultsFTD was associated with early, severe, and selective VEN losses, including a 74% reduction in VENs per section compared with control subjects. VEN dropout was not attributable to general neuronal loss and was seen across FTD pathological subtypes. Surviving VENs were often dysmorphic, with pathological tau protein accumulation in Pick's disease. In contrast, patients with Alzheimer's disease showed normal VEN counts and morphology despite extensive local neurofibrillary pathology.InterpretationVEN loss links FTD to its signature regional pattern. The findings suggest a new framework for understanding how evolution may have rendered the human brain vulnerable to specific forms of degenerative illness. Ann Neurol 2006;60:660–667
Determination and stability of sex

Published: December 2006

AbstractHow is the embryonic bipotential gonad regulated to produce either an ovary or a testis? In males, transient early activation of the Y chromosome Sry gene makes both germ cells and soma male. However, in females, available evidence suggests that the process of ovary sex determination may take place independently in the germline and somatic lineages. In addition, in contrast to testis, in ovary somatic cells, female‐to‐male gonadal sex reversal can occur at times throughout ovary development and maturation. We suggest that a single gene pathway, likely hinging on the Foxl2 transcription factor, both initiates and maintains sex differentiation in somatic cells of the mammalian ovary.

Theoretical Study of Microwave Enhanced Thermal Decontamination of Oil Contaminated Waste

Published: December 2006

AbstractThis paper demonstrates that microwave enhanced thermal decontamination of oil contaminated waste is a potentially important and highly efficiency approach to achieving the required environmental discharge limit. Numerical simulation of microwave thermal decontamination of oil contaminated wastes within an applicator known to support high electric field strengths was used to assess the influence of electric field and power loss density distributions on oil removal from the waste materials. It was found during this study that the water content plays the most important role in oil removal. As the microwave receptors within the material matrix, water molecules absorbed the bulk of the applied microwave energy. This energy was subsequently transferred to the oil in the form of heat, and was shown to cause thermal desorption. The boiling point of oil can also be reduced when it is mixed with water, since free water is beneficial to uniform heating, whilst bound water has a significant effect on the latter stages of oil removal. The experimental and simulation results suggest that the lowest residual oil levels were achieved when the sample material had a high dielectric loss factor and was placed in the position of maximum electric field strength. The cost of using a microwave technique for the remediation of oily waste can be up to 20 times lower than conventional heating.
