Authors: Thiessen Maclean , Soriano Andrea Michelle , Loewen Hal John , Decker Kathleen Margaret
Published: December 2020

Background

During the COVID-19 pandemic, the use of telemedicine by oncology physicians in Manitoba, Canada, has increased to limit the risk of exposure to the virus for both patients and health care providers. It is not clear how telemedicine impacts the information needs of patients or the experience of receiving cancer care.

Objective

The objective of this study is to describe how the use of telemedicine impacts the information needs and experience of patients with cancer and their informal caregivers (ie, family and friends) and identify directions for future research.

Methods

This review will include all studies addressing telemedicine in the cancer context including those using quantitative, qualitative, and mixed methods approaches. This scoping review will be conducted using the methodology described by the Joanna Briggs Institute. In collaboration with a librarian scientist specializing in health sciences, a comprehensive search will be undertaken to identify and retrieve relevant reports published in English from 1990 to the present. Databases searched will include MEDLINE, CINAHL, EMBASE, Scopus, Cochrane Library, and PsycINFO. Data will be extracted by two independent reviewers, synthesized, and reported in a summary table and in a narrative format describing what has been reported regarding the impact of telemedicine by physicians in oncology on the experience of patients and their informal caregivers and their receipt of information.

Results

The results from this scoping review are expected to be available by late spring 2021.

Conclusions

The results from this scoping review will be useful for informing practice as well as directing future research, both in the context of COVID-19 and beyond.

Published: December 2020

The photocatalytic activity of Nanopillars-TiO2 thin films was assessed in the degradation of Bromophenol blue (BPB) dye from aqueous solution under batch reactor operations. The thin films were characterized by the XRD, SEM and AFM analytical methods. BET specific surface area and pore sizes were also obtained. The XRD data showed anatase phase of TiO2 particles with average particle size of 25.4 and 21.9 nm, for S1 and S2 catalysts respectively. The SEM and AFM images indicated the catalyst composed with Nanosized pillars of TiO2, evenly distributed on the surface of the substrate. The average height of the pillars was found to be 180 and 40 nm respectively for the S1 and S2 catalyst. The BET specific surface area and pore sizes of S1 and S2 catalyst were found to be 5.217 and 1.420 m2/g and 7.77 and 4.16 nm respectively. The photocatalytic degradation of BPB using the UV light was studied at wide range of physico-chemical parametric studies to determine the mechanism of degradation as well as the practical applicability of the technique. The batch reactor operations were conducted at varied pH (pH 4.0 to 10.0), BPB initial concentration (1.0 to 20.0 mg/L) and presence of several interfering ions, i.e., cadmium nitrate, copper sulfate, zinc chloride, sodium chloride, sodium nitrate, sodium nitrite, glycine, oxalic acid and EDTA in the photocatalytic degradation of BPB. The maximum percent removal of BPB was observed at pH 6.0 and a low initial concentration of the pollutant highly favours the photocatalytic degradation using thin films. The presence of several interfering ions suppressed the photocatalytic activity of thin films to some extent. The time dependence photocatalytic degradation of BPB was demonstrated with the pseudo-first-order rate kinetics. Study was further extended with total organic carbon measurement using the TOC (Total Organic Carbon) analysis. This demonstrated an apparent mineralization of BPB from aqueous solutions.

Monosodium glutamate is naturally available non-essential amino acids, which found in naturally occurring foods and used as flavour enhancer worldwide. Monosodium glutamate is believed to be linked with diverse health problems. The aim of the study was toxic effects of monosodium glutamate (MSG) and the protective role of L-carnitine, light on the available literature from last 25 years about diverse toxicity studies which had been carried out on animal and human models. Google scholar, NCBI, PUBMED, EMBASE, Wangfang databases, and Web of Science databases were used to retrieve the available studies. MSG was linked with deleterious effects particularly in animals including induction of obesity, diabetes, hepatotoxic, neurotoxic and genotoxic effects showed in Literature. Few reports revealed increased hunger, food intake, and obesity in human subjects due to MSG consumption. Hepatotoxic, neurotoxic, and genotoxic effects of monosodium glutamate on humans carried out very limitedly. High consumption of monosodium glutamate may be linked with harmful health effects showed in available literatures. So, it is recommended to use common salt instead of MSG. Furthermore, intensive research is required to explore monosodium glutamate–related molecular and metabolic mechanisms. L-carnitine can protect from Hepatotoxic, neurotoxic, renal impairment and genotoxic effects functionally, biochemically and histopathologically with a corresponding reduction of oxidative stress.

Water management has become an important research area as the scarcity of water increases day-by-day around the world. Rain water harvesting is one of most efficient way of managing water resources which could be utilized for different purposes during the needy period such as drought, drinking water and irrigation. This paper presents a method for identification of suitable dam site using both Multi-Criteria Decision Analysis (AHP) and GIS to establish the hydrological characteristics of suitable region for dam construction. This method considers six (6) criteria such as slope, size of catchment, geology, land use characteristics, proximity to settlement and proximity to river. Each criterion was assigned a weight depending on relative importance with other criteria. Thematic layers were then generated based on these criteria and overlaid in GIS environment to obtain layers identifying the suitable sites for dam construction.

A detailed survey was conducted on people living within and beyond 50m from mobile base station, on thirteen (13) different non-specific health symptoms faced by inhabitants living near mobile tower in six different localities in Champhai district for the first time, since mobile tower was erected in 2009. Power density of RF radiation have also been measured within and outside 50m from the station for GSM900 and GSM1800 in the same locality. The measured power densities have been compared with standard limits given by various scientific bodies like International Commission on Non-Ionizing Radiation Protection (ICNIRP 1998), Bioinitiative Report (Sage and Carpenter 2012) ,Salzburg Resolution (Haumann et al. 2000) and current Indian National Standards. The radiation level is under permissible limits as per the guidelines adopted in India. Also the results were statistically analysed and compared by using Kruskal Walli’s t-test. It was found that the comparisons are statistically significant with p<0.05 in all the six localities where headache, memory loss and muscle pain are the most common health complaints. From the correlation studies, it has been found that there is a strong positive correlation between power density and complaints on non-specific health symptoms.
Local history and geographical education in Latvia
Authors:   Latvian Geographical Society, Buile Natālija
Published: December 2020

Since its establishment in 1923, the Latvian Geographical Society (LGB) has been a non-governmental organisation that brings together geographers and people who are interested in research into nature and human geography. Local history and geography has always been an integral part of the teaching process. Today, the knowledge held by members of the society and the research-based educational work carried out by the society about different cities and regions for the improvement of the study content of Latvian geography is diverse. The Latvian Geographical Society cooperates most extensively with local government, organising seminars and conferences in Latvia at the regional level. This cooperation has helped teachers to schedule lessons and excursions outside the classroom.
Regional human capital disequilibria: the case of youth migration in Latvia
Authors:   University of Latvia, Apsite-Berina Elina , Burgmanis Girts ,   University of Latvia, Prusakova Laura ,   University of Latvia
Published: December 2020

Riga stands out within Latvia as a significant pool of economic and education-related opportunities. Students and young people are traditionally more mobile and move towards destinations where self-advancement is accessible. Thus, this study aims to describe the human capital disequilibria in the regions of Latvia by analysing youth in the age group from 15 to 34 years and making a comparison between the years 2011 and 2018. The backbone of the study is an analysis of changes in regional unemployment rates and changes in the number of young people in certain regions outside the capital, as well as the general trend for the proportion of young people to decrease in some regions since 2011. The main research questions addressed are: how can the core-periphery model be applied to the regions of Latvia, and to what extent do economic opportunities explain regional inequality? The results indicate that Riga is a core, geographically, and the functionally related regions of Pieriga and Zemgale are semi-peripheral regions. However, the regions of Vidzeme, Latgale and Kurzeme are “places of lower rank” or peripheral regions, which are losing young people in the competition both with the core areas within the country and with other attractive destinations abroad.
Latvia’s progress towards a retirement society: ageing trends in Latvian municipalities
Authors:   University of Latvia, Grube Gunta , Paiders Juris ,   University of Latvia
Published: December 2020

This paper analyses the ageing of the population, which may become one of the most important social changes of the 21st century in the European Union. This work uses statistics from the Central Statistical Bureau (CSB) of Latvia, as well as statistics prepared by the State Social Insurance Agency of Latvia (SSIA). The results suggest that t the economic development and the stabilisation of employment in Riga and Riga region in the second decade of the 21st century was ensured not by generational change or migration, but by the inclusion of members of the population who had previously been economically inactive into the labour market. This may lead to the conclusion that around 2030, the ageing of the population will become one of the most serious problems in Pieriga.
El tratamiento gramatical de la verdad en la lengua Andoque
Authors: Landaburu John
Published: December 2020

Este artículo analiza las diversas funciones de una clase de palabras obligatoriamente presentes en la mayoría de los enunciados de la lengua andoque del Amazonas. Todo enunciado asertivo-enunciado que afirma algo, contiene en andoque una palabra llamada "asertivo". En un primer momento analizamos la función sintáctica del asertivo y la expresión de esta función. En un segundo mo­mento describimos la forma de los distintos componentes del asertivo. En un tercer momento, analizamos el signifi­cado de estos componentes. Mostramos como los significa­dos se articulan en una estructura conceptual referente al tratamiento de la verdad, a la credibilidad del enunciado, a la categorización del tiempo. En el centro mismo de la lengua se nos revela una preocupación rigurosa por la fundamentación epistemológica del discurso, preocupación mucho menos gramaticalizada en nuestras lenguas europeas. Este trabajo es parte de los resultados de una investiga­ción linguística entre la gente andoque, iniciada en 1970 con la ayuda de la Universidad de Los Andes de Bogotá y proseguida en 1973-1974 bajo los auspicios del Centre National de la Recherche Scientifique de París. La investi­gación ha dado lugar a varias publicaciones, entre ellas una descripción detallada de la lengua de los Andoques ( cf. Bibliografía final).
Contested Spaces, Shared Concerns
Authors: Stutts Sarah , Saintonge Kenneth , Jordan Nicholas , Wasson Christina
Published: December 2020

Roadways are sociocultural spaces constructed for human travel which embody intersections of technology, transportation, and culture. In order to navigate these spaces successfully, autonomous vehicles must be able to respond to the needs and practices of those who use the road. We conducted research on how cyclists, solid waste truck drivers, and crossing guards experience the driving behaviors of other road users, to inform the development of autonomous vehicles. We found that the roadways were contested spaces, with each road user group enacting their own social constructions of the road. Furthermore, the three groups we worked with all felt marginalized by comparison with car drivers, who were ideologically and often physically dominant on the road. This article is based on research for the Nissan Research Center - Silicon Valley, which took place as part of a Design Anthropology course at the University of North Texas.

El ascenso de la transformación digital obliga  a renovar la Educación Superior lo que se espera es tener una Universidad  del futuro lo cual  implica transitar del modelo I+D Innovación + Desarrollo al modelo I+D +ii Innovación + Desarrollo+ Innovación inteligente; es decir que la Institución Educativa estará conformada  de inteligencia humana e inteligencia artificial y esta se articula a partir de dos componentes el currículo inteligente que ofrece libertad en las formaciones y en las innovaciones académicas y las innovaciones  científicas y tecnológicas. Lo que significa que estas Instituciones deben avanzar de acuerdo con el progreso de la sociedad y brindar su aporte al desarrollo tecnológico-científico. La función de la Academia tradicionalmente a lo largo de la historia ha sido la formación de élites y el formar grupos específicos para un mercado laboral. Sin embargo, esta función trasciende más allá de lo tradicional actualmente como lo es el aporte a la sociedad por medio de sus investigaciones que se conviertan en aportes que influyan en el desarrollo productivo pues la escasa vinculación con el sector productivo hace que trabajen de manera aislada y que sus funciones académicas como las investigaciones se vuelvan intrascendentes.  La sociedad en general, demanda una Universidad la cual no solo vaya más allá de la simple transmisión de conocimientos sino una Institución que contribuya al desarrollo a través de la ciencia y la tecnología
Clinical Decision Making Regarding Benzodiazepine Use in PTSD Treatment
Authors: bernardy nancy , Barnett Erin , Lund Brian , Alexander Bruce , Parker Louise , Jenkyn Aaron , Friedman Matthew
Published: December 2020

i. Rationale, Aims and Objectives: Despite guideline recommendations
against their use, clinicians prescribe benzodiazepines for various
symptoms to patients with posttraumatic stress disorder (PTSD).
Clinicians’ reasons in making these decisions are not fully understood.
This qualitative study sought to characterize factors identified by
prescribing clinicians in clinical decision making in PTSD regarding the
use of benzodiazepines. ii. Methods: The descriptive study involved
semi-structured interviews with 26 prescribing clinicians across
thirteen VA medical centers. Our overall aim in the study was to explore
clinicians’ benzodiazepine practices in veterans with a PTSD diagnosis.
We audio-recorded, transcribed, and analyzed the interviews using
grounded theory methodology. iii. Results: Facilitators and barriers
that contribute to benzodiazepine prescribing to veterans with PTSD
included organizational, provider, and patient aspects. Most providers
interviewed indicated that they inherited patients already on these
medications initiated by other clinicians. These providers, as well as
others interviewed, voiced concerns that tapering benzodiazepines may
cause more harm than the risks of maintenance, particularly in older
patients. Clinicians who noted consistent treatment practices among
their hospital colleagues found it easier to decrease both new and
maintenance benzodiazepine prescribing. iv. Conclusions: Patients with
PTSD at increased risk of harms, such as older patients, are still
receiving benzodiazepines suggesting that innovative solutions are now
needed to decrease use. Specific protocols for inherited patient
caseloads, increased dissemination of effective psychotherapies for
symptoms such as insomnia and anxiety and the use of direct to consumer
educational materials should help to foster needed culture change and
increased evidence-based PTSD practice.
Description and validation of a novel score (Flow Index) as a clinical indicator of the level of respiratory support to children on high flow nasal cannula.
Authors: tripathi sandeep , Mcgarvey Jeremy , Shaikh Nadia , Meixsell Logan
Published: December 2020

Objective: Describe & validate flow index (FiO2×flow rate/weight) to
report the degree of respiratory support to children on high flow nasal
cannula (HFNC) Methods: Retrospective chart review. Children managed
with HFNC from 01/01/15 to 12/31/19. Variables included in the flow
index (weight, FiO2, flow rate) and outcomes (hospital and ICU length of
stay [LOS], escalation to the ICU) extracted from medical records.
Max flow index defined by the earliest timestamp when patients FiO2×Flow
rate was maximum. Step-wise regression used to determine the
relationship between outcome (length of stay and escalation to ICU) and
flow index Results: 1537 patients met the study criteria. Median 1st and
maximum flow index of the population 24.1 and 38.1, respectively. Both
1st and maximum flow indexes showed a significant correlation with the
LOS (r 0.25 and 0.31). Correlation for the index was stronger than that
of the variables used to calculate them and remained significant after
controlling for age, race, sex, and diagnoses. Mild, moderate, and
severe categories of 1st and max flow index derived using quartiles and
showed significant age and diagnosis independent association with LOS.
Patients with 1st flow index >20 and maximum flow index
>59.5 had increased odds ratio of escalation to ICU (OR
2.39 and 8.08). The 1st flow index had a negative association with rapid
response activation. Conclusions: Flow index is a valid measure for
assessing the degree of respiratory support for children on HFNC. High
flow index associated with longer hospital LOS and the risk of
escalation to ICU.

Secular and Post-Secular Understanding of the Concept of Personality
Authors: Maler Arkady M.
Published: December 2020

The article shows the development of the concept of personality in the history of philosophy as the key value of European civilization. The main problem of understanding personality is that this concept arose exclusively in the context of the formation of Orthodox Christian dogma, where the personality is God himself and man created in the image and likeness of God. Thus, it is in Christianity that the concept of personality has fundamental ontological basis and therefore only in Christianity it has the absolute value. But in the secular philosophy of Modern times the concept of personality has been subjected to radical secularization and is now identified only with the concept of the human individual resulting from biological evolution and the totality of social relations. Hence, from the secular point of view, a human being cannot be a person until certain social realization is achieved, which makes the concept of personality itself virtual and optional. However, in the situation of post-secularism and in connection with the revival of the Christian consciousness, resuscitation of the concept of person as an ontological value is possible. But the return of religious civilization means the revival not only of Christianity but also of all other religions, and the growth of new, neo-pagan and syncretic religious movements, where the concept of personality can be subjected to even greater devaluation than in the secular philosophy of Modern times.

The Problem of Belarusian Literary Language in Belarusian Conservative Intellectual Tradition (the Second Half of the 19th – Early 20th Centuries)
Authors: Kiselev Alexander A.
Published: December 2020

The author of the article claims that Belarusian Orthodox intelligentsia of the conservative and liberal-conservative orientation was negative to the idea of creating Belarusian literary language. That was due to the fact that the Orthodox intelligentsia opposed the replacement of the Russian language with Belarusian. According to them, the rejection of the Russian language would impede the cultural and social development of the Belarusian people. At the same time, some of the intellectuals believed that Belarusian dialects, the literary tradition of the Grand Duchy of Lithuania and the natives of the Belarusian lands themselves participated actively in the formation of the modern Russian literary language. Russian literary language was viewed as mutual for all East Slavic ethnic groups that made up the Russian nation.

Project of Resolving the Belarusian Issue During World War I (1914–1918): Regional Aspects
Authors: Lavrinivich Dmitry S.
Published: December 2020

At the beginning of the World War I, the center of Belarusian national movement was located in Vilna, where the editors of «Nasha Niva» journal and the « Belarusian society» formed two main views on the national development of the Belarusian people in the 20th century. The first project assumed national autonomy within the Federal Russian Republic. The representatives of the latter advocated the cultural and economic development of the Belarusian people while maintaining close ties with Russia. After the occupation of Vilna by the German troops and the fall of the tsarist government in 1917 independent Belarusian organizations emerged in all provincial cities and towns. Belarusian organizations, with centers in Minsk, advocated the national-territorial autonomy of Belarus as part of democratic Russia, and then the idea of creating an independent state, the Belarusian People’s Republic, prevailed. Belarusian organizations of Mogilev province were influenced by the ideology of Westrusism, but gradually evolved to the left and became closer to the Belarusian Socialist Community (BSG). The most conservative organization, the Belarusian People’s Union, operated in Vitebsk province.
Reasons for the Onset of the Uniat Clergy’s Movement Towards Orthodoxy in the Russian Empire in the Beginning of the 19th Century
Authors: Romanchuk Protopriest Alexander
Published: December 2020

The article studies the system of pre-conditions that caused the onset of the uniat clergy’s movement towards Orthodoxy in the Russian Empire in the beginning of the 19th century. The author comes to the conclusion that the tendency of the uniat clergy going back to Orthodoxy was the result of certain historic conditions, such as: 1) constant changes in the government policy during the reign of Emperor Pavel I and Emperor Alexander I; 2) increasing latinization of the uniat church service after 1797 and Latin proselytism that were the result of the distrust of the uniats on the part of Roman curia and representatives of Polish Catholic Church of Latin church service; 3) ecclesiastical contradictions made at the Brest Church Union conclusion; 4) division of the uniat clergy into discordant groups and the increase of their opposition to each other on the issue of latinization in the first decades of the 19th century. The combination of those conditions was a unique phenomenon that never repeated itself anywhere.
The Lessons of the Three Forcible Ukrainizations of Little Russia (1917 – 1919, 1920s – Beginning of 1930s, 2014 – 2019)
Authors: Tsipko Alexander S.
Published: December 2020

The article is devoted to the research and author’s interpretation of the three attempts to forcibly Ukrainize Little Russia, namely in the revolutionary period 1917 – 1919, in the period of Stalin reign in the 1920s and the beginning of the 1930s of the 20th century and also in the period of 2014 – 2019 during Peter Poroshenko’s presidency. All the attempts were accompanied by several competing “Ukraine projects” formed at the early stages of the experiments with the Ukrainian state system caused by the collapse of the Russian Empire. Using the contemporary material the author shows that the competence of those projects still continues nowadays and the idea of national Ukrainian statehood has failed to become real and remains just the declaration of the Ukrainian intelligentsia. The author draws corresponding parallels with the events in Belarus and considers Belorussian intelligentsia the main driving force of the separatist sentiments towards Russia, when the basic mass of the population does not support the nationalistic idea like the population of the Ukraine in the previous years.

Soft luscious lips, honey soft brown eyes, a beautiful lavender aroma that you can smell even from a mile away; her soft alluring curls bouncing off her shoulders as she strides to the front of the church. Am tempted to walk to the front to kiss her, claiming her as mine, but I know better than to do that. My heart beats rapidly as I watch her laugh. Her laughter is a sweet melody to my ears; a beautiful song I could never get enough off like a hymn I need in my life. I remove my gaze from her as I try to pull myself together before I do something that I will regret. How can those boys make her laugh like that when I couldn’t even make her smile at me?

Authors: Marinich Nikolai V. , Valeriy Rodionov А. , Koval Anastasia A. , Sverchkov Andrey V. , Mamontov Fedor E.
Published: December 2020

Object and purpose of research. The object of the research is a fundamentally new waterjet, intended for installation on ships of increased seakeeping performance with discrete-variable bottom deadrise. The purpose of the research is to develop and experimentally test the impeller and water duct for a variety of waterjet design possible for installation aboard vessels with large deadrise operating in severe weather conditions.
Materials and methods. Test data for waterjet impellers obtained at KSRC Cavitation Tunnel for Special Propulsors.
Main results. The study made it possible to select optimal impeller geometry and develop the shapes for water inlets and water ducts of three waterjet designs with partial-pressure water inlets: two waterjets with isolated single-elbow water ducts and inlets on the bottom section with medium deadrise, "II"design; two waterjets with combined water duct and inlets on the bottom section with maximum deadrise and double jet, “X” design; single waterjet with bifurcating two-elbow water duct and a pair of water inlets on the bottom section with maximum deadrise, “Y” design.
Conclusion. The studies have shown that developed waterjet impeller features good hydrodynamic and cavitation characteristics, and possible air suction creates a smooth, rather than sharp, force decrease.

Object and purpose of research. The object of research was a model of a fast seaworthy boat with discretevariable bottom deadrise and two waterjet propulsors. The purposes of research were to experimentally determine hydrodynamic characteristics of the model in calm water and head regular waves corresponding to the irregular waves of sea states 3 and 4, as well as to determine the possibility of air penetration to waterjet inlets for two variants of their arrangement on model bottom in head-wave conditions, numerical simulation of the full-scale boat movement in oblique irregular waves (sea state 4) for two variants of waterjet arrangement, with an assessment of waterjet duct aeration exposure.
Materials and methods. Model hydrodynamics was estimated experimentally by means of towing tests in highspeed seakeeping basin in calm water and head regular waves using standard test equipment; air penetrations were recorded by a GO PRO digital video camera installed on the model above the water inlets. Numerical simulation of the full-scale boat movement was carried out in Star-CCM+ CFD package.
Main results. The study yielded the curves of towing resistance, running trim and sinkage versus model speed in calm water and head regular waves of different length for two longitudinal CG positions, as well as the areas of air penetration to waterjet inlets on model bottom. Analysis of the experimental data enabled the estimation of attainable speed for the boat with displacement of 50 and 29 tf in waves for given delivered power. Numerical simulation of the full-scale boat movement in oblique irregular waves for two variants of waterjet arrangement has also been carried out.
Conclusion. The results have shown that seakeeping performance of the boat is quite satisfactory and that the most obvious way to mitigate air penetrations is to reduce the speed. Other important factors were shifting the waterjet inlet towards the transom and to the CL, as well as shifting the longitudinal CG forward. The obtained results can be used to select the position of the waterjet inlets on boat bottom in order to increase waterjet efficiency. Using the methods of numerical hydrodynamics, the characteristics of the waterjets have been obtained, the probability and volumes of air penetrations to waterjet ducts (for different variants of waterjet arrangement) at several angles of oblique irregular waves have been estimated.

Object and purpose of research. The object of work is steel “38ХН3МФА”, planned for use in the propeller shafts manufacture of the lead-ship (project 10510), and less strong steel “40XH”, used in the propeller shafts manufacture for icebreakers of lower ice categories and lower power. The purpose of the study is to compare the fatigue strength of these steel grades.
Materials and methods. Investigations of the fatigue strength characteristics of steels were carried out by cyclic tests of flat notched specimens in air and cylindrical specimens in fresh water.
Main results. It is shown that lowest fatigue strength results correspond to external cyclic loading of specimens with stress concentrator (notch). But even in these conditions, fatigue strength of 38ХН3МФА steel is better than that of 40XH steel.
As for the tests of smooth samples in fresh water, 38ХН3МФА steel also has a clear advantage over 40XH steel.
Conclusion. The studies have shown that fatigue strength characteristics of 38ХН3МФА steel in the air and in corrosive environment exceed those of 40XH steel. Environmental sensitivity and stress concentration of 38ХН3МФА steel turned out to be higher than for 40KH steel.

The aim of this study is to evaluate the seasonal variations of Mosul dam lake by measuring the temperature, dissolved oxygen (DO) and biochemical oxygen demand (BOD) during the period from July 2018 to April 2019. Twenty two sites were selected within the studied lake. The obtained results were integrated with the geographical information system (GIS) using spatial images to create maps utilizing Arc map software. These maps were used to demonstrate the concentrations of the investigated parameters during the study period. The results show that all parameters were within the accepted levels, indicating the good status of the lake.

Este artículo tiene como objetivo reflexionar sobre la competencia lingüística y el desarrollo de hábitos lectores en la educación superior, centrándose específicamente en el análisis de la competencia léxica de los futuros profesores de inglés de Primaria y sus usos lectores en esta lengua extranjera. En la investigación han participado 34 estudiantes del Itinerario de intensificación de inglés, del Grado de Educación Primaria de la Facultad de Educación de la Universidad de Extremadura. Dichos estudiantes completaron un cuestionario para determinar la extensión de su vocabulario receptivo y un sencillo test en el que informaban de sus hábitos de lectura. La mayoría de los alumnos no tiene aún adquirido el conocimiento del léxico de las 3000 palabras más frecuentes y tampoco tiene afianzado un hábito lector en lengua extranjera. Por último, en el análisis de correlación efectuado no se aprecia relación entre la frecuencia de lectura y el tamaño del vocabulario.
Una mirada a los clásicos en la formación inicial de maestro desde la Lectura Fácil

Published: December 2020

Presentamos una experiencia desde la que se ha pretendido, por un lado, incluir la Lectura Fácil (LF) en la formación inicial de los maestros del grado en Educación Primaria de la Universidad de Cádiz como estrategia para el acercamiento a las obras y autores clásicos para una educación literaria y, por otro lado, abordar esta metodología desde los Proyectos de Trabajo Global (PTG). De esta manera, recogemos el desarrollo de la experiencia ­–desde un punto de vista vivencial– a lo largo de tres momentos: en primer lugar, desde la fase inicial de exploración de los planteamientos de la LF; en segundo lugar, desde los procesos de adaptación del texto clásico y, por último, desde el diseño del PTG a partir del texto adaptado. Los resultados han mostrado un interés creciente por este tipo de propuestas para la compresión y disfrute de los textos clásicos y la necesidad de la formación en esta línea de trabajo entre los futuros docentes.

Rice is a relatively salt-sensitive crop with the reproductive and seedling stages being the most sensitive. Two separate experiments were conducted to isolate potential determinants of salinity tolerance and to investigate the possibility of modulating salt tolerance by exogenous ascorbic acid (AsA) application. Rice plants were imposed to salinity (EC= 10.0 dS m-1) both at the seedling and reproductive phases of growth. Salinity at the seedling stage resulted a sharp decline in shoot and root growth related traits including leaf chlorophyll content, while hydrogen peroxide (H2O2) and malondialdehyde (MDA) levels increased. Plants experienced with salinity at the reproductive phases of growth showed a significant reduction in yield attributing traits while the tissue levels of H2O2 increased. Exogenous AsA application reversed the negative impact of salt stress, modulating the root and shoots growth and yield related traits and lowering H2O2 and MDA levels. FL-478 was identified as the most tolerant genotype at the seedling stage, with Binadhan-10 being the most tolerant at the reproductive stage. Grain yield panicle-1 significantly and positively corrected with number of filled grains panicle-1, panicle length, plant height, and spikelet fertility, and negatively correlated with H2O2 levels. Stress tolerance indices clearly separated the tolerant and susceptible genotypes. A principal component analysis revealed that the first two components explained 87% of the total variation among the genotypes. Breeding efforts could therefore to undertake for developing salinity tolerance by manipulating endogenous AsA content in rice.
