A New Quasi Sujatha Distribution
Authors: Shanker Rama , Shukla Kamlesh Kumar
Published: September 2020

The aim of this paper is to introduce a new quasi Sujatha distribution (NQSD), of which the following are particular cases: the Sujatha distribution devised by Shanker (2016 a), the size-biased Lindley distribution, and the exponential distribution. Its moments and moments-based measures are derived and discussed. Statistical properties, including the hazard rate and mean residual life functions, stochastic ordering, mean deviations, Bonferroni and Lorenz curves and stress-strength reliability are also analysed. The method of moments and the method of maximum likelihood estimations is discussed for estimating parameters of the proposed distribution. A numerical example is presented to test its goodness of fit, which is then compared with other one-parameter and two-parameter lifetime distributions.

Authors: Nafees Sana , Zafaryab Md. , Mehdi Syed H. , Zia Bushra , Rizvi Moshahid A. , Khan Md. Asad
Published: September 2020

Cancer is one of the most lethal diseases in the world. Because of the high death rate associated with
cancer and the side effects of chemotherapy and radiation therapy, patients require alternative strategies for its
treatment. Ginger (Zingiber officinale) has enormous medicinal properties and health benefits. In this review, we
discuss the basic mechanism by which gingerol (an active component of ginger) modulates a variety of cell
signaling pathways linked to cancer, including Nuclear Factors (NF-κB), Signal Transducer and Activator of
Transcription 3 (STAT3), Activator Protein-1 (AP-1), β-catenin, Growth Factors Receptors (EGFR, VEGFR);
Mitogen-Activated Protein Kinases (MAPK) and pro-inflammatory mediators (TNF-α and COX-2). Both in
vitro and in vivo studies support the role of gingerol in cancer. The efficacy of gingerol by clinical trials has also
been reported. Importantly, natural agents are already in clinical trials against various kinds of cancer. An effort
has been made through this comprehensive review to highlight the recent developments and milestones achieved
in cancer therapies via studies based on different cell lines using gingerol.

The supercontinuum generation in water droplets with nanoparticles of citrate silver in the temperature range of 2–22 °C, as well as in the ice droplets frozen to −15.0 °C, has been studied. It was found that the intensity of the supercontinuum emission under the excitation by a train of femtosecond laser pulses exponentially decays along the droplet diameter and it increases linearly with increasing NP concentration. The emission spectrum of supercontinuum in water droplet with NPs and the generation of localized plasmons with fluorescence at the 430 nm wavelength was studied. The movement of a heat wave along the diameter of a small frozen drop with a speed of 190 mm / s accompanying exponentially decaying supercontinuum radiation was recorded. The modeling of heat transfer processes in the frozen droplet during the formation of a heat wave has been carried out.

Published: September 2020

In CuIn5S8 crystals grown by the method of slow cooling of the melt at a constant temperature gradient, intense luminescence and nanosecond relaxation of the photocurrent are observed at a high level of optical excitation. Three emission bands with energies of 1.52, 1.48, and 1.465 eV are distinguished in the photoluminescence spectra. The photoactivation of the crystal in the range 300-600 K is explained by an increase in the hole mobility in the valence band with increasing temperature.
Solvatochromic Study of Supramolecular Amphiphile Based on Calix[4]arene Connected to a Fluorescent Benzofurazan Moiety at Lower Rim: Evaluation of Ground and Excited State Dipole Moments-=SUP=-*-=/SUP=-
Authors: Joshi S.
Published: September 2020

Photophysical properties of a supramolecular amphiphile of calix[4]arene having benzofurazan moiety at the lower rim, L has been studied. Electronic absorption and fluorescence spectra of L have been recorded in wide range of solvents of different polarities and data were used to study solvatochromic properties. The ground state and the excited state dipole moment of L were estimated from the Bakhshiev's and Bilot-Kawaski's equations. High value of dipole moment is observed for excited state as compared to ground state value and this is attributed to more polar excited state of molecule. Also, fluorescence emission peak undergoes a bathochromic shift with increase in the polarity of the solvent, confirming π-> π* transition. Scanning electron microscopy reveals that the aggregation of L is increased on going from the polar to non polar solvents. Keywords: solvatochromism, benzofurazan, dipole moment, quantum yield, absorption, fluoresence.

Продемонстрировано увеличение квантового выхода рекомбинационной ИК люминесценции коллоидных квантовых точек Ag2S до 35 раз в результате формирования оболочек ZnS, SiO2 при одновременном увеличении среднего времени жизни люминесценции. Для квантовых ядро/оболочка Ag2S/ZnS покрытых тиогликолевой кислотой показано уменьшение излучательной и безызлучательной констант рекомбинации, которое объяснено локализацией электронов в оболочке, а дырок в ядре. Для квантовых точек ядро/оболочка Ag2S/SiO2 покрытых 2-меркаптопропионовой кислотой наблюдалось увеличение констант излучательной и уменьшение безызлучательной рекомбинации. В этом случае рост константы излучательной рекомбинации обусловлен локализацией электронов и дырок в ядре. Уменьшение константы безызлучательной рекомбинации объяснено пассивацией интерфейсных дефектов квантовых точек при формировании оболочки.

Published: September 2020

Scattering of light by disordered structures is normally detrimental to their applicability in many optoelectronic devices. However, some micro and nanostructures are useful in enhancing several optical and thermal properties like emission, heat diffusion etc. For this purpose, we have optimized the low temperature hydrothermal growth method for the ZnO micro tubes which leads to the growth of ZnO as mono dispersed micro tubes. Further, these samples were used to enhance the fluorescence efficiency of disordered media consisting of micro tubes of ZnO and fluorescein dye and to optimize the thermal diffusion of the mixture which will help us optimize the composition of these microscopic inclusions in designing a random lasing medium. Dual beam thermal lens method was used for this purpose. Keywords: thermal lens, thermal fluidics, thermal diffusivity, ZnO micro tubes, fluorescein.
Evaluation of an Occupational Exercise Training Program for Firefighters: Mixed Methods Pilot Study
Authors: Leary Miriam , Thomas James , Hayes Ryan , Sherlock Lori
Published: September 2020

Background

Occupational exercise training programs can improve overall health and fitness in firefighters, but evidence beyond clinical and performance outcomes is needed before fire departments invest in and successfully adopt health promotion programs.

Objective

This mixed methods pilot study sought to pair clinical and performance outcomes with participants’ qualitative feedback (eg, participants’ enjoyment, lifestyle behavior changes, and team structure) with the goal of informing recommendations for future programs.

Methods

Professional firefighters participated in a 14-week occupational exercise training program with assessments conducted pre- and posttraining. Clinical outcomes included weight, BMI, body fat percentage, resting heart rate, systolic blood pressure, and diastolic blood pressure. Performance outcomes included the sharpened Romberg balance test, 1-repetition maximum leg press and bench press, graded exercise test (estimated VO2max), knee range of motion, shoulder flexibility, and hamstring flexibility. Self-administered surveys (Short Form-36, International Physical Activity Questionnaire, Barriers Self-Efficacy Scale, and Barriers to Being Active Quiz) were completed. In 3 private focus groups of 3 to 4 participants, firefighters' experiences in the training program and their health behaviors were explored.

Results

Male firefighters (n=14; age: mean 36.4, SD 2.6 years) completed 20 training sessions. There were no significant changes to weight (P=.20), BMI (P=.15), body fat percentage (P=.16), systolic blood pressure (P=.12), estimated VO2max (P=.34), balance (P=.24), knee range of motion (left: P=.35; right: P=.31), or hamstring flexibility (P=.14). There was a significant decrease in diastolic blood pressure (P=.04) and significant increases in shoulder flexibility (P<.001) and leg press 1-repetition maximum volume (P=.04). Participants reported improvements in overall health, endurance, flexibility, and mood as well as improvements to team environment and health behaviors around the station; however, there was a decline in overcoming barriers to physical activity.

Conclusions

A 14-week program of exercise training in firefighters elicited improvements in clinical, performance, and self-reported physical activity outcomes. This occupational exercise training program for firefighters increased time spent exercising, improved team building, and led to physical and mental health benefits. Results from this pilot study set a broad, informed, and meaningful foundation for future efforts to increase firefighter participation in occupational fitness programs.

Published: September 2020

Background

Most of the mortality resulting from COVID-19 has been associated with severe disease. Effective treatment of severe cases remains a challenge due to the lack of early detection of the infection.

Objective

This study aimed to develop an effective prediction model for COVID-19 severity by combining radiological outcome with clinical biochemical indexes.

Methods

A total of 46 patients with COVID-19 (10 severe, 36 nonsevere) were examined. To build the prediction model, a set of 27 severe and 151 nonsevere clinical laboratory records and computerized tomography (CT) records were collected from these patients. We managed to extract specific features from the patients’ CT images by using a recently published convolutional neural network. We also trained a machine learning model combining these features with clinical laboratory results.

Results

We present a prediction model combining patients’ radiological outcomes with their clinical biochemical indexes to identify severe COVID-19 cases. The prediction model yielded a cross-validated area under the receiver operating characteristic (AUROC) score of 0.93 and an F1 score of 0.89, which showed a 6% and 15% improvement, respectively, compared to the models based on laboratory test features only. In addition, we developed a statistical model for forecasting COVID-19 severity based on the results of patients’ laboratory tests performed before they were classified as severe cases; this model yielded an AUROC score of 0.81.

Conclusions

To our knowledge, this is the first report predicting the clinical progression of COVID-19, as well as forecasting severity, based on a combined analysis using laboratory tests and CT images.
Automated Fall Detection Algorithm With Global Trigger Tool, Incident Reports, Manual Chart Review, and Patient-Reported Falls: Algorithm Development and Validation With a Retrospective Diagnostic Accuracy Study (Preprint)
Authors: Dolci Elisa , Schärer Barbara , Grossmann Nicole , Musy Sarah Naima , Zúñiga Franziska , Bachnick Stefanie , Simon Michael
Published: September 2020

BACKGROUND

Falls are common adverse events in hospitals, frequently leading to additional health costs due to prolonged stays and extra care. Therefore, reliable fall detection is vital to develop and test fall prevention strategies. However, conventional methods—voluntary incident reports and manual chart reviews—are error-prone and time consuming, respectively. Using a search algorithm to examine patients’ electronic health record data and flag fall indicators offers an inexpensive, sensitive, cost-effective alternative.

OBJECTIVE

This study’s purpose was to develop a fall detection algorithm for use with electronic health record data, then to evaluate it alongside the Global Trigger Tool, incident reports, a manual chart review, and patient-reported falls.

METHODS

Conducted on 2 campuses of a large hospital system in Switzerland, this retrospective diagnostic accuracy study consisted of 2 substudies: the first, targeting 240 patients, for algorithm development and the second, targeting 298 patients, for validation. In the development study, we compared the new algorithm’s in-hospital fall rates with those indicated by the Global Trigger Tool and incident reports; in the validation study, we compared the algorithm’s in-hospital fall rates with those from patient-reported falls and manual chart review. We compared the various methods by calculating sensitivity, specificity, and predictive values.

RESULTS

Twenty in-hospital falls were discovered in the development study sample. Of these, the algorithm detected 19 (sensitivity 95%), the Global Trigger Tool detected 18 (90%), and incident reports detected 14 (67%). Of the 15 falls found in the validation sample, the algorithm identified all 15 (100%), the manual chart review identified 14 (93%), and the patient-reported fall measure identified 5 (33%). Owing to relatively high numbers of false positives based on falls present on admission, the algorithm’s positive predictive values were 50% (development sample) and 47% (validation sample). Instead of requiring 10 minutes per case for a full manual review or 20 minutes to apply the Global Trigger Tool, the algorithm requires only a few seconds, after which only the positive results (roughly 11% of the full case number) require review.

CONCLUSIONS

The newly developed electronic health record algorithm demonstrated very high sensitivity for fall detection. Applied in near real time, the algorithm can record in-hospital falls events effectively and help to develop and test fall prevention measures.
Usability, Perceived Usefulness, and Shared Decision-Making Features of the AFib 2gether Mobile App: Protocol for a Single-Arm Intervention Study (Preprint)
Authors: Kapoor Alok , Andrade Andreza , Hayes Anna , Mazor Kathleen , Possidente Carl , Nolen Kim , Hegeman-Dingle Rozelle , McManus David
Published: September 2020

BACKGROUND

The Centers for Disease Control and Prevention has estimated that atrial fibrillation (AF) affects between 2.7 million and 6.1 million people in the United States. Those who have AF tend to have a much higher stroke risk than others. Although most individuals with AF benefit from anticoagulation (AC) therapy, a significant majority are hesitant to start it. To add, providers often struggle in helping patients negotiate the decision to start AC therapy. To assist in the communication between patients and providers regarding preferences and knowledge about AC therapy, different strategies are being used to try and solve this problem. In this research study, we will have patients and providers utilize the AFib 2gether app with hopes that it will create a platform for shared decision making regarding the prevention of stroke in patients with AF receiving AC therapy.

OBJECTIVE

The aim of our study is to measure several outcomes related to encounters between patients and their cardiology providers where AFib 2gether is used. These outcomes include usability and perceived usefulness of the app from the perspective of patients and providers. In addition, we will assess the extent and nature of shared decision making.

METHODS

Eligible patients and providers will evaluate the AFib 2gether mobile app for usability and perceived usefulness in facilitating shared decision making regarding understanding the patient’s risk of stroke and whether or not to start AC therapy. Both patients and providers will review the app and complete multiple questionnaires about the usability and perceived usefulness of the mobile app in a clinical setting. We will also audio-record a subset of encounters to assess for evidence of shared decision making.

RESULTS

Enrollment in the AFib 2gether shared decision-making study is still ongoing for both patients and providers. The first participant enrolled on November 22, 2019. Analysis and publishing of results are expected to be completed in spring 2021.

CONCLUSIONS

The AFib 2gether app emerged from a desire to increase the ability of patients and providers to engage in shared decision making around understanding the risk of stroke and AC therapy. We anticipate that the AFib 2gether mobile app will facilitate patient discussion with their cardiologist and other providers. Additionally, we hope the study will help us identify barriers that providers face when placing patients on AC therapy. We aim to demonstrate the usability and perceived usefulness of the app with a future goal of testing the value of our approach in a larger sample of patients and providers at multiple medical centers across the country.

Emotional Reactions and Likelihood of Response to Questions Designed for a Mental Health Chatbot Among Adolescents: Experimental Study (Preprint)
Authors: Mariamo Audrey , Temcheff Caroline Elizabeth , Léger Pierre-Majorique , Senecal Sylvain , Lau Marianne Alexandra
Published: September 2020

BACKGROUND

Psychological distress increases across adolescence and has been associated with several important health outcomes with consequences that can extend into adulthood. One type of technological innovation that may serve as a unique intervention for youth experiencing psychological distress is the conversational agent, otherwise known as a chatbot. Further research is needed on the factors that may make mental health chatbots destined for adolescents more appealing and increase the likelihood that adolescents will use them.

OBJECTIVE

The aim of this study was to assess adolescents’ emotional reactions and likelihood of responding to questions that could be posed by a mental health chatbot. Understanding adolescent preferences and factors that could increase adolescents’ likelihood of responding to chatbot questions could assist in future mental health chatbot design destined for youth.

METHODS

We recruited 19 adolescents aged 14 to 17 years to participate in a study with a 2×2×3 within-subjects factorial design. Each participant was sequentially presented with 96 chatbot questions for a duration of 8 seconds per question. Following each presentation, participants were asked to indicate how likely they were to respond to the question, as well as their perceived affective reaction to the question. Demographic data were collected, and an informal debriefing was conducted with each participant.

RESULTS

Participants were an average of 15.3 years old (SD 1.00) and mostly female (11/19, 58%). Logistic regressions showed that the presence of GIFs predicted perceived emotional valence (β=–.40, P<.001), such that questions without GIFs were associated with a negative perceived emotional valence. Question type predicted emotional valence, such that yes/no questions (β=–.23, P=.03) and open-ended questions (β=–.26, P=.01) were associated with a negative perceived emotional valence compared to multiple response choice questions. Question type also predicted the likelihood of response, such that yes/no questions were associated with a lower likelihood of response compared to multiple response choice questions (β=–.24, P=.03) and a higher likelihood of response compared to open-ended questions (β=.54, P<.001).

CONCLUSIONS

The findings of this study add to the rapidly growing field of teen-computer interaction and contribute to our understanding of adolescent user experience in their interactions with a mental health chatbot. The insights gained from this study may be of assistance to developers and designers of mental health chatbots.

Authors: Zaidi Ahmar Urooj , Shah Nirmish , Thomas Ryan , Shareef Muhummad O. , Hannan Bryan , Zaidi Arshia Urooj , Callaghan Michael Urban
Published: September 2020

BACKGROUND

While the relationship of pain and sleep in sickle cell disease (SCD) has been described, the data are evolving around this complex relationship. In a prior study, using actigraphy and patient reported outcomes, our group determined that sleep quality deteriorates leading up to and during pain, and can be measured using an actigraph. We found that sleep parameters, particularly sleep fragmentation, is affected during pain episodes. This study is the first to determine the feasibility of identifying these parameters in real time using a Fitbit® Charge 3.

OBJECTIVE

This was a fourteen-week pilot trial investigating the feasibility of following activity profiles and sleep fragmentation in real time by using the Fitbit® Charge 3 in ten patients with sickle cell disease. The primary endpoint of this study was the percent of days data was captured from the Fitbit (target 75%). The secondary endpoint was to determine the feasibility of real-time monitoring of actigraphy and sleep fragmentation in steady-state sickle cell disease patients and to establish baseline actigraphy and sleep fragmentation indices in patients with SCD.

METHODS

Eligible subjects included patients with a confirmed diagnosis sickle cell disease, ages > or equal to 12 years and who have experienced > or equal to 2 episodes of pain requiring documented unplanned medical intervention with opioid treatment in the prior 12 months. This was a fourteen-week pilot trial investigating the feasibility of monitoring activity profiles and sleep fragmentation in real time by using the Fitbit Charge 3 in patients with sickle cell disease.

RESULTS

A mean of 88.4% of possible days per patient were captured (maximum – 100% and minimum – 44%) in 10 patients, and the primary endpoint was met. Feasibility was demonstrated on a post-study survey where patients reported no problems with the device, excellent practicality, no pain, discomfort or frustration wearing the device and complete satisfaction.

CONCLUSIONS

This is the first study showing the ability of the FitBit® Charge 3 to be used as an actigraph in sickle cell disease patients to monitor activity and sleep. This provides clinicians with a unique and tangible ability to track activity and sleep in the clinical and research setting. The FitBit® Charge 3 may be also be useful in prediction of sickle cell outcomes of interest, offer the ability to intervene, and follow how these metrics change with new therapies.

Наночастицы имеют свойства, сильно зависящие от их размеров. Существует огромное число методов, которые используются для определения их размеров, однако нет четких критериев для определения наиболее подходящего для разных типов наночастиц. В данной работе были использованы два разных метода для определения размеров наночастиц в коллоидном растворе. Проведено сравнение методов динамического рассеяния света и метода акустической спектроскопии. Были определены точность и корректность этих методов. Кроме того, выявлены преимущества и недостатки методов динамического рассеяния света и акустической спектроскопии при определении размеров наночастиц.

Nanoparticles have properties that depend critically on their dimensions. There are large numbers of methods that are commonly used to characterize these dimensions, but there is no clear consensus
on which method is most appropriate for different types of nanoparticles. In this work, two different characterization methods were applied to characterize the dimensions of nanoparticles in colloidal solution. Namely, dynamic light scattering and acoustic attenuation spectroscopy are compared with one another. The accuracy and precision of these two methods applied to nanoparticles of silica were determined. In addition, the advantages and disadvantages of the methods of dynamic light
scattering and acoustic spectroscopy in determining the size of nanoparticles are revealed.
Particularidades de la prescripción en los supuestos de abuso de las formas jurídicas y simulación en el Código Tributario chileno
Authors: Navarro Schiappacasse María Pilar
Published: September 2020

The Chilean General Anti Avoidance Rules (GAARs) aim to deprive the fiscal effects resulting from a tax planning declared, by a tribunal, as abusive or as a sham. These institutions present some interesting characteristics in terms of the limitation period which distances them from what until now had been the absolute rule. In effect, even if the abuse and the sham are ruled in objective ways, the legislator considers the taxpayer’s actions are performed in bad faith. The consequence is an increase of the limitation period from three to six years by the application of the extraordinary limitation period’s rules. Additionally, in order for the Tax Administration to be able to inspect effects from this type of tax planning, it is necessary that the acts, contracts or legal business implemented by the taxpayer and declared elusive, have been taken place in revisable tax periods.

Published: September 2020

Work by relying on conscience, to decide whether someone is guilty or not. The judge profession is one of the noble professions. The judge determines a person's actions. Judges are called noble, clearly addressing this profession has a higher degree. In convicting a criminal, besides at least two valid evidence, a judge's conviction is needed. The judge is called the representative of God on earth. However, judges are still ordinary people who are not free from mistakes. Miscarriage of justice happens a lot in the decisions they make. This study examines the prevention of miscarriage of justice in the implementation of judges’ tasks. This research is designed by using normative-juridical method, which is an approach that uses a positivist-juridical conception, namely that law is identical with written norms created by the authorities, so far the law is made as a normative system that is autonomous closed and independent of people's lives. The results show that Justice is something aspired by the people of Indonesia. Judges are the most important element in realizing justice that is highly aspired. Judges as representatives of God who hold to the "For the sake of justice based on the Almighty God" develop a difficult task. Many miscarriage of justice occurs in the community. Judges as a profession that has a higher degree must hold on to professional ethics to avoid miscarriage of justice.

Along with the times, there has occur and grown up and many problems about employment matter in which there many more employment relationship works without parity between the responsibility and the rights from the employer to the employee/ workers. As the consequence of the inclusion of business competition climate, it caused the businessman look for ways how to maximize the production output by reducing the costs. This circumstance has influenced the workers right becomes ruled out and then arises statement of workers to claim their pending rights. This study aims to find out the industrial relationship matter related to the business competition climate, and to find out the settlement mechanism of industrial relationship conflict based on regulation number 2 year of 2004 about settlement of industrial relationship matter. This study used juridical normative method. This juridical research is carried out towards references object. Moreover, this study applied primary, secondary, and tertiary legal material. The result of the study showed that the impact of employment matter was more complicated. That is why the labor problems should be seen as the industrial relation matter. This matter also comes as the consequence of Indonesia as the Welfare State where the State should take a part in every part of social life. This means that the State has important role to solve the problem of industrial relationship.

The most detrimental thing is the use of domain names on internet networks that often use company name, brand and services without permission from the brand owner. The position of the brand is very important in the world of advertising and marketing. That happens because consumers in choosing a product related to the reputation of a brand, based on a sense of trust in the experience in using products with that brand. Aside from being a differentiator of a product with other products, a brand is also a valuable and commercial asset that has moral rights and economic rights. This study aims to analyse the preventive and repressive legal protection of trademark rights holders in e-commerce transactions. This research was conducted using the normative legal research method. The results of this study indicate that the preventive legal protection of trademark rights holders in e-commerce transactions is to register the trademark. The emphasis on preventive protection in this research is related to guarantees of the exercise of rights for brand rights holders in e-commerce transactions. That the presence of the government by drafting the Electronic Commerce Act and conducting socialization related to the legal protection of the parties in e-commerce is expected to be able to provide legal certainty of legal protection. Repressive legal protection in resolving trademark disputes is expected to create a guarantee for the enforcement of the rights of registered trademark rights holders in e-commerce transactions. Settlement of trademark disputes in e-commerce transactions can be done in 2 (two) ways, namely litigation and non-litigation.

The formation of Indonesia's national legal system cannot be separated from the politics of law, because it is used as a guide in the process of making and enforcing the law to achieve a dream and national goal. The formation of the legal system in Indonesia has not gone well, Indonesia should have its own law. By having its own law, Indonesia will have national identity and will be seen as advanced by other countries. The formation of the national legal system in Indonesia is heavily influenced by external elements. It should maintain all the material sources of law that already exist in Indonesia. The objective of this study is to describe the formation of the national legal system in the State of Indonesia. This study uses a normative approach by using secondary data from library materials. The results of this study indicate that the formation of a national legal system is a process of developing a legal system and along with its element. With the development of the national legal system, it must be able to replace the Dutch colonial legal products with its own legal products. The development of the national legal system is a way to make changes in Indonesian legal products that must be in accordance with the values that are in people's lives. In the process of legal development, it is impossible to be separated from a legal politics.

El objetivo del presente estudio fue evaluar el tiempo de manejo y el comportamiento indicativo de estrés en bovinos durante su paso por una manga recta. Se utilizaron ocho hatos de 50 animales Brahman x Pardo Suizo, cada hato constituido proporcionalmente por animales jóvenes, adultos, machos y hembras. Cuatro hatos se asignaron al azar a cada uno de los dos tratamientos: en el primer tratamiento, el hato se manejó en grupos de 4-5 animales (TS), mientras que, en el segundo, se manejó en grupos de 10 a 12 animales (TG). El manejo consistió en llevar los animales a través de una manga de 13 m de longitud donde recibieron una aplicación subcutánea de Ivermectina al 1%. Durante su paso por la manga, el tiempo promedio para manejar a los animales en cada tratamiento (42.5 ± 2.2 vs 51.04 ± 1.9 min; P<0.05), así como el número de animales que vocalizaron (5.5 ± 0.6 vs 7.7±0.2; P<0.05), se regresaron (6.3 ± 0.4 vs 9.5 ± 0.6; P<0.05) y saltaron sobre sus compañeros (2.7 ± 0.5 vs 5.2 ± 0.5; P<0.05), fue menor en TS que en TG. Sin embargo, no se encontró diferencia entre los tratamientos (P>0.05) para el número de animales que se golpearon (TS: 2.7 ± 0.4 y TG: 5.5 ± 1.7) o se cayeron (TS: 2 ± 0.4 y TG: 3.7 ± 1.0). Se concluye que el manejo de bovinos en grupos pequeños requiere menos tiempo y puede ser menos estresante y peligroso que cuando se manejan grupos más numerosos.

El presente trabajo tiene por finalidad evaluar y caracterizar tanto la posición y tendencia de la competitividad de la carne bovina de México frente a la oferta externa de los principales países productores, como analizar la relación entre esta ventaja mercantil, la producción y la exportación nacional que permita proponer estrategias que la potencialicen en el mediano plazo. Para lograr este objetivo se calcularon cuatro indicadores de resultado tomando en cuenta el procedimiento postulado por el Instituto Interamericano de Cooperación para la Agricultura. El volumen de oferta primaria de carne bovina posiciona a México en el séptimo lugar mundial, mientras que como exportador se coloca en el quinceavo puesto; se halló que la exportación del país de este cárnico tiene como destino mayoritario el mercado de los Estados Unidos de América y que la producción nacional presenta un bajo nivel de competitividad en el mercado internacional. En el comportamiento de la producción y exportación de la carne bovina mexicana influyen factores que se vinculan con las características del mercado y del proceso comercial, así como con fenómenos naturales, los cuales determinan tanto la productividad de la canal, como la generación de saldos exportables y de valor para la economía del país.

Published: September 2020

This study examined the type of mathematical tasks in two Australian and two Indonesian mathematics textbooks for 7th-grade students. The quantitative data were collected from the coding results of the tasks in the textbooks. The tasks were coded based on six categories: the presentation forms, the cognitive requirements, the contextual features, the information provided, the number of steps required, and the numbers of answers. Both the similarities and differences in the mathematical tasks provided in the selected textbooks were analysed. The coding results reveal that the majority of tasks in both the Australian and Indonesian textbooks were presented in verbal and combined forms. Routine and closed tasks were still dominant in the four textbooks. More than 93% of tasks in the four textbooks had sufficient information for students to solve the problem. One of the Australian textbooks had a higher proportion of tasks with real-world contexts than the other textbooks. One of the Indonesian textbooks showed a high proportion of tasks requiring multiple steps or procedures. These results were used to explore the learning opportunities offered by the textbooks, and the possible influence on students’ performances in international assessments. Some recommendations for the refinement of the textbooks and future research are also outlined at the end of the study.

Water regime of rivers is an important characteristic of the surface land waters as a natural environment component and object of economic use. The reaction of the rivers’ water regime to the climatic changes, including the case of extreme hydro-meteorological events, has not been studied carefully yet. It is necessary to adapt the water part of national economy to the current trends and characteristics of rivers’ water and ice regime. The analysis and inventory of these trends are required to make appropriate decisions. The authors present the methodology and the results of mapping the current European Russia rivers’ water regime and its modern transformation. The resulting map series includes the maps of the season beginning months, the coefficient of natural flow regulation, the average runoff depth for the "historical" period, extreme monthly equal discharge rate, the ratio of average monthly discharge between seasons, the runoff depth in the "modern" period and its change compared to the "historical" one, a map of water regime transformation, as well as a number of supplementary climatic maps reflecting changes in temperature and precipitation regime. The obtained maps allowed revealing numerous spatiotemporal tendencies, including intensification of the hydrological cycle; the increase in the annual runoff depth in the middle of the East European Plain; increase of absolute unevenness of summer low-water runoff and decrease of relative unevenness; the decrease of maximum discharge; significant change of the ratio of discharge components for the most rivers of the European Russia, the most important feature of which is decreasing the share of snowmelting component.

Published: September 2020

The authors describe a software suite for determining tilt degrees of tower-type structures according to ground laser scanning indication. Defining the tilt of the pipe is carried out with a set of measured data through approximating the sections by circumferences. They are constructed using one of the simplest search engine optimization methods (evolutionary algorithm). Automatic filtering the scan of the current section from distorting data is performed by the method of assessing the quality of models constructed with that of least squares. The software was designed using Visual Basic for Applications. It contains several blocks (subprograms), with each of them performing a specific task. The developed complex enables obtaining operational data on the current state of the object with minimal user participation in the calculation process. The software suite is the result of practical implementing theoretical developments on the possibilities of using search methods at solving optimization problems in geodetic practice.
