Sobre voces y poder: hacia una semiótica del silencio
Authors: García Dussán Éder
Published: May 2021

En este artículo proponemos pensar el acontecimiento del silencio desde dos puntos de vista: como signo-síntoma y como elemento de poder social. Para avanzar en esto diferenciamos, por un lado, los actos de callar y silenciar y, dentro de este, el de ser silencioso o ser silenciado, apoyados en las propuestas de Jacques Lacan y Roland Barthes. Posteriormente, fijamos la reflexión en dos casos concretos que involucran sectores de letrados: el del cada vez mayor silencio que aqueja a los docentes en el siglo XXI y el de los pactos de silencio en el orbe político del país en el siglo XX. Tal esfuerzo permite concluir que la figura del letrado, docente o autor de obras culturales comunica desde lo ausente con la intención de denunciar un malestar estructural, ora desde sus omisiones, ora desde sus alusiones académicas.
La cuestión del cuerpo en el campo de la comunicación. Pensando aportes y desafíos a partir del caso del Área Cuerpo y Comunicación de la Universidad de Buenos Aires
Authors: Singer Mariela
Published: May 2021

En los últimos años, el interés por la cuestión del cuerpo se ha visto reforzado en el campo de la comunicación. La masificación de los feminismos y las transformaciones estético-sensibles de la última década han profundizado desplazamientos epistemológicos tendientes a conceder mayor relevancia a la problemática de la corporalidad y la comunicación entre cuerpos. La valorización del cruce “cuerpo y comunicación” se expresa en la apertura de espacios institucionales, en la elección de objetos de estudio en tesis de grado y posgrado, y en desarrollos curriculares.

Fanaticism is an over-zealous attitude towards a particular perspective or attitude regarding community practice. For the recitation pilgrims, the Zuhdi teacher himself has a figure that is one of the things that is positive for everyone, because the respected figure is considered to be able to provide benefits that are considered positive and deserve fanaticism from many communities. How a person interacts is inseparable from the environment that shapes a person's personality. This type of research is a descriptive-qualitative field research, the method used by the author is a method for examining an object from a state of condition or a system of thought from the subject, the researcher collects a number of data obtained directly from the research location using information obtained from the object research through data collection instruments namely observation and interviews. Because Zuhdi teacher recitation worshipers at the Mosque of Jami are very many and from various backgrounds. Data collection techniques used are fanaticism scale, semi-structured interviews, and non-participant observation with subjects totaling 4 people with characteristics of recitation congregation aged 20-50 years. Based on the results that researcher have obtained in all four subjects have a dimension of fanaticism, the amount of interest and love for one type of activity, S and MI subjects have a strong interest, while the MA and Z subjects have a very strong interest because it attaches photos of Master Zuhdi at home and even saves photos and his deeds in special notes. So, fanaticism is a concept adopted by someone who has contributed to his life and makes his emotions become more mature or wise. Fanaticism in this study is one form of love and belonging to a society/group of figures who are believed to have made a major contribution in themselves and their lives.

Critical infrastructure are facilities that are crucial for the smooth functioning of the state. Disruption of critical infrastructure can affect people's lives. From this point of view, it is important that employees with appropriate competencies operate in such infrastructures. These competencies can be collected in the competency model. This is a list of competencies that describe the characteristics of the employee in terms of skills, knowledge, behaviour, and experience. The purpose of this paper is to highlight the main features of competency models in critical infrastructures. This represents an opportunity for further research and implementation of competency models in critical infrastructure systems. However, since it all starts at the top, we discuss the competencies of managers. The integration of competency models into critical infrastructures is an important area, as such models make it easier and faster to acquire key employees.

Critical infrastructure encompasses those capabilities that are crucial to the state and disruption would have a significant impact and serious consequences for national security, economy, health, safety, security, and human wellbeing. People take critical infrastructure for granted, but it is fraught with great risks. Risk is anything that can prevent the achievement of certain goals and create an outcome that was not foreseen. Just analysing what can happen and acting is called risk management. We find that risk management is becoming an increasingly comprehensive and demanding activity to protect critical infrastructure from emergencies due to intentional or unintentional causing. Improper management can have a negative impact on users, owners, and operators of critical infrastructure. The research used a critical review of secondary sources and a method of synthesis, with the help of which we described why it is necessary to successfully manage risks.

Published: May 2021

Digital transformation refers to the process of redefining the way enterprises do business using digital technology. It changes existing organizational processes within and between organizations. The transformation affects all organizations, but poses a particular challenge for small and medium-sized enterprises. To begin a digital transformation process, enterprises must first be aware of the factors influencing the transformation, so they can further develop their digital maturity roadmap and continue the digital transformation process. In this paper, we aim to identify the most important internal and external factors that guide the digital transformation process and the dominant theories behind them. The findings suggest that organizational factors, together with technology and environment, may provide a comprehensive view of digital transformation. The results also showed that data and its quality are increasingly attracting attention in professional circles and data science communities, but are not yet sufficiently considered in the context of digital transformation.

Published: May 2021

Social changes lead to changes in cooperation between school and parents. This cooperation has become more necessary and intensive. The most desirable form of cooperation between school and parents is a partnership between them. Features of the partnership cooperation are two-way communication, mutual support, making decision together and promotion of learning. This can be achieved if teachers have well-developed communication competencies. In the article I discuss them as essential competencies of a teacher that enable good cooperation of an educational institution with parents. Communication is a social interaction. It shows the way and quality of the relationship between the participants in communication. If schools strive for good communication competencies of their employees, especial for teachers, they can expect positive responses from parents. This contributes to the optimal development of the child.

Published: May 2021

t Continuing medical education (CME) is the right and obligation of every health worker for continuous professional development and one of the conditions for license renewal. The need for CME arose as a consequence of constant innovations in medicine as a science, as well as the introduction of new technologies in therapy, diagnostics and health care. It is necessary (mandatory) for all health workers, because it provides monitoring and reform of the education and health system according to WHO recommendations. A CME is a set of educational activities that serve to maintain, develop, or increase the knowledge, skills, and professional accomplishments and relationships that a physician and other health care professionals use to provide services to patients, the public, or the profession. The CME system ensures that the latest knowledge and the latest treatment techniques are transferred through additional and continuous form of internal or external training to doctors and medical technicians, and aims to raise the level of expertise and improve the quality of health care in all forms of health care and daily practice. E-learning is a step forward in CME. The aim of this paper is to present the e-learning system of education of medical workers in Serbia, as well as to present the attitudes of health workers about e-learning continuous medical training through empirical research.

Published: May 2021

Background: Rural poultry farming with improved dual purpose chicken varieties is fast growing in the country. The meat quality of cocks and its acceptance by the consumer is important for its propagation as dual purpose variety. The two way cross produced by PD-1 xPD-4 (improved Aseel) was evaluated for growth, carcass and meat quality. Metohds: The growth, carcass and meat quality traits were evaluated in a two way cross developed and propagated for rural poultry farming at ICAR-Directorate of Poultry Research, Rajendranagar, Hyderabad, Telangana. The data collected on 232 birds for growth, 40 birds for carcass and 20 birds for meat quality were utilized for the study. Result: The body weight and shank length significantly (P≤0.05) differed between the sexes from six weeks onwards with higher (P≤0.05) body weights and longer shanks in males. The six week body weight and shank length were 578.23±8.22g and 78.93±6.22 mm in males and 548.28±7.20 g and 76.15±5.28 mm in females, respectively. The Least squares means for body weight at 12 weeks of age in males and females were 1652.61±21.49 and 1367.86 ±14.99 g, respectively. Males had strong legs with significantly (P≤0.05) high proportion of thigh meat. The effect of sex was non-significant on Dressing percentage (DP), neck, back and breast meat proportions. The DP was 71.12±0.22% in males and 72.51±0.43 % in females, respectively. The bone proportion was higher (P≤0.05) in males. Abdominal fat proportion was significantly (P≤0.05) higher in pullets. Feather proportion was higher (P≤0.05) in males. Sex did not show any significant variation on the pH, Shear force value (SFV) and Hydroxy Proline (HP) values. The yellowness (b*) differed (P£0.05) between the sexes and it was lower in males. The fat and moisture content differed significantly (P≤0.05) between the sexes. Fat proportion was higher (P≤0.05) in females (3.57±0.05) than in males (2.97±0.01). Protein and ash proportions were similar in both the sexes. The sensory attributes ranged from 6.55 to 7.15 on an eight point scale in two-way cross meat indicating better consumer acceptability. The study concluded that, two-way cross with ideal growth, carcass and optimum meat quality and reasonable consumer acceptability may be a suitable variety for propagating in rural and tribal areas under free range backyard conditions.

Published: May 2021

Background: A practice development project was undertaken with nurses from acute, older persons, primary care and rehabilitation services across two counties in the north east of the Republic of Ireland over a 12-month period in 2018-19. For acute hospital patients aged over 65 years, the average length of stay in 2017 was 44.44 days; for medical patients it was 55.69 days. The average length of stay on the pre-discharge unit was 36.5 days, after which 54% of patients transferred to nursing homes, 14% to rehabilitation services and 18% to home. Aims and objectives: The objectives were to provide a more person-centred, integrated approach to care across the services, to facilitate patient and family involvement in care planning and to understand why so few patients transferred home, with the aims of reducing lengths of stay in the acute hospital and increasing the number of patients going home. Methods: Person-centred and Lean Six Sigma approaches were combined. Lean Six Sigma provided the framework for data collection, analysis, planning and scheduling, while engagement within the team and with other colleagues, patients and their families was underpinned by person-centred principles. Results: The project resulted in an average reduction in length of stay on the pre-discharge unit of 16 days. More than 47% of patients are now being discharged home compared with 18% in 2017. Conclusion: A combination of Lean Six Sigma and person-centred approaches was used to shift from the status quo and transform care by implementing process changes that promoted better communication and facilitated a smoother transition for patients through the services. This combination was effective in promoting a culture that supports patients and their families to determine and achieve their preferred health outcomes. Implications for practice: Understanding culture and context within healthcare organisations is an essential part of practice development, especially in cross-service initiatives Creating a shared vision across all services that puts the patient at the centre of care supports patients and families to choose and achieve their care preferences Lean Six Sigma and person-centredness can be used in combination to design person-centred improvements that benefit staff, patients and their families

Published: May 2021

Background: It is predicted that care home provision for older people will need to increase significantly over the next 30 years, requiring a skilled workforce that expands to meet this growing need. Innovative practice development strategies are required to support the existing workforce and provide incentives to help recruit new staff. Aim: This article aims to explore the use of the peer-assisted learning model to support the development of communities of practice in care home settings in an area of England. Method: Care home teams were invited to university-based workshops and their experiences of using peer-assisted learning were elicited through narrative telephone interviews undertaken with care home managers. Findings: Three overarching themes were identified relating to practice development: context, process and impact. Through peer-assisted learning, staff were empowered to share their expertise and knowledge with colleagues, resulting in enhanced communication, respect and person-centred resident care. Managers viewed peer-assisted learning as a sustainable, low-cost investment in staff development. Conclusion: This article contributes to practice development by presenting reflections on an innovative initiative to facilitate the use of peer-assisted learning in educational practices in the care home workforce. Combining the philosophies of community of practice and peer-assisted learning provides a model that can foster practice development in the care home setting. Further, this work can support the development of communities of practice that operate across care homes on a national/international basis. Implications for practice: This article describes a sustainable practice development model that can be used in the care home setting Grounding practice development in the philosophies of peer support and communities of practice can promote a climate of mutual respect and enhanced communication Improved communication and sharing of expertise within care home teams offers the potential for improved resident-centred care provision

Published: May 2021

In the context of the economic crisis caused by the spread of coronavirus infection, the global labour market has faced serious challenges, on the timeliness and effectiveness of the response to which the viability of the world economy today depends. The crisis is global in nature and has a significant impact on investment, global value chains and international trade, with serious consequences not only for the economy, but also for the working-age population in all countries of the world. The global economic turmoil caused by the coronavirus pandemic requires a thorough analysis of the scale of its consequences in order to determine the most rational solutions. A situation of uncertainty about the future, fear of devastating consequences, and pessimistic forecasts were the companions of the first days of the pandemic. This article provides the first estimates of the level of unemployment and employment in various countries of the world in 2020. The article is divided into two parts due to its large volume. The first part reveals the reasons for the differences in the dynamics of unemployment in different countries of the world, calculates the elasticity of employment by GDP, considers the consequences of the pandemic for the global labor market in the context of changes in workers' incomes, and identifies the segments of the labor market that are most susceptible to impact. The second part of the article examines in detail the state of the Russian labour market and the dynamics of the main indicators of socioeconomic development of Russia before and during the pandemic, provides forecast values of indicators, reveals the features of adaptation of the Russian labor market to new challenges and their differences from the mechanisms of self-regulation during previous economic shocks, while focusing on the changes occurring in the informal sector of the Russian economy

Arely Medina. Islam-latino. Identidades étnico-religiosas. Un estudio de caso sobre los mexicanos musulmanes en Estados Unidos. Guadalajara
Authors: Torre Renée de la
Published: May 2021

No puedo dejar de imaginar las reaccionar de extrañeza al leer el título de este libro. ¿Qué es eso del Islam Latino?¿Que el Islam no era columna religiosa del mundo árabe y lo Latino representaba la expansión mundial del catolicismo? Y al leer el subtítulo exclamarán: ¿De qué trata en realidad este libro? ¡No entiendo eso de mexicanos musulmanes en Estados Unidos! El estudio de Arely Medina es sorprendente precisamente por estas mezclas duras de identidades que han sido descolocadas por procesos diaspóricos (flujos migratorios, redes sociales, medios masivos de comunicación, internacionalización religiosa) que desplazan territorialmente y culturalmente a individuos y a diferentes tradiciones religiosas que anteriormente permanecieron profundamente anclados en tradiciones, territorios y grupos étnicos o sociales.

Published: May 2021

This study was aimed to investigate the relationship between the psychological status of oral health care workers (OHCWs) and the willingness to treat a patient during the COVID-19 pandemic. This cross-sectional study was carried out on oral health care workers at ten different dental hospitals in Pakistan from March to July 2020. Information on the socio-demographic status, and willingness to report for duty and treat patients during the COVID-19 pandemic were assessed using a self-administered questionnaire. The psychological impact of the COVID-19 pandemic was assessed using the Urdu version of the Generalized Anxiety Disorder Scale and Impact of Events Scale. Simple and multiple linear regression tests were used for analysis. A total of 392 OHCWs participated in this study and 25% of them had moderate to severe anxiety levels and only 14% had post-traumatic stress disorder. About 26% of the OHCWs were willing to work and treat patients during the COVID-19 pandemic and they had lower anxiety and stress scores. Greater anxiety and stress were associated with participants who were older, female, single, married, living with family and friends. The adjusted coefficients of GAD and IES scores were greater in participants who were not willing and unsure to work compared to their colleagues who were willing. The OHCWs are anxious and stressed because of the COVID-19 outbreak and that affects the perception of whether they should work and treat patients during the pandemic.

Using virtual reality treadmill as a locomotion technique in a navigation task: Impact on user experience – case of the KatWalk
Authors: Cherni Heni , Nicolas Souliman , Métayer Natacha
Published: May 2021

This paper reports empirical results from a study on the impact of the KatWalk virtual reality omnidirectional treadmill on the user experience. The omnidirectional treadmill is a mechanical device, that allows the user to perform locomotive motion in any direction, allowing for 360 degrees of horizontal movement. This locomotion method appeared as a potential solution of the locomotion problem in virtual reality after the emergence and the democratization of the new generation of head-mounted display systems such as HTC Vive and Oculus Rit. However, little empirical work has been done to test the efficiency of the tool as a locomotion technique in virtual environments. Twenty-four subjects (13 females, mean age = 30.38, SD = 6.32) participated in the experiment. Results showed that the tool is suitable for traveling in virtual environments seen through head-mounted display systems, whether they are composed of plan or bumpy ground, with or without obstacles.
Change Mechanism of Strength of Soil-rock Mixture Freezing-thawing Interface under Different Rock
Authors: Gang Li , Tao Huang , Zhen Li , Miaomaio Bai
Published: May 2021

With global warming and accelerated degradation of permafrost, the engineering problems caused by the formation of weak zones between the shallow and permafrost layers of soil–rock mixture (S-RM) slopes in permafrost regions have become increasingly prominent. To explore the influence of rock content on the shear strength of the S-RM freezing–thawing interface, the variation in the shear strength for different rock content is studied herein using direct shear tests. In addition, a 3D laser scanner is used for obtaining the topography of the shear failure surface. Combined with the analysis results of the shear band-particle calculation model, the influence of the rock content on the shear strength of the interface is explored. It was found that the impact threshold of the rock content on the interface strength and failure mode is approximately 30%, when the rock content (R) is > 30% and that the shear strength increases rapidly with increasing rock content. When R ≤ 30%, the actual shear plane is similar to waves; when R > 30%, the shear plane appears as gnawing failure. The shear strength of S-RM freezing–thawing interface mainly comes from the bite force and friction between particles. The main reason for the increase in shear strength with increasing rock content is the increase in bite force between particles, which makes the ratio of bite force to friction force approximately 1:1.

The Future of Essentially Derived Variety (EDV) Status: Predominantly More Explanations or Essential Change
Authors: Smith John Stephen C.
Published: May 2021

This review examines the categorization of Essentially Derived Varieties (EDV) introduced in the 1991 revision of the Convention of the Union internationale pour la protection des obtentions végétales (UPOV). Challenges in the implementation of the concept and progress made on a crop-by-crop basis to provide greater clarity and more efficient implementation are reviewed. The current approach to EDV remains valid provided i) clarity on thresholds can be achieved including through resource intensive research on an individual crop species basis and ii) that threshold clarity does not lead to perverse incentives to avoid detection of essential derivation. However, technological advances leading to new varieties resulting from the simultaneous introduction or change in expression of more than “a few” genes will so challenge the concept to require a new Convention. Revision could include deletion of the concept of essential derivation and revision on a crop-by-crop basis of the breeder exception. Countries that allow utility patents for individual plant varieties per se should consider removing that possibility unless plant breeders utilize those encouragements for risk taking and investment to broaden the germplasm base upon which the long-term sustainability of plant breeding resides.
Physical Performance Testing of a Prototype Gerotor Pump Operating in Liquid and Gas/Liquid Conditions
Authors: Ejim C. E. , Xiao J. , Oshinowo L.
Published: May 2021

Gerotors are positive displacement pumps and potential artificial lift options in the oil and gas industry. This study presents the performance characteristics from physical testing of a unique one-stage, equal-walled gerotor pump design operating in oil and oil/air mixtures. The pump was tested at various rotational speeds in a flow loop. The performance results were obtained to ascertain potential design optimizations of the pump before embarking on manufacturing and testing of the field prototype pump.

A physical prototype of a one-stage 400 series gerotor pump, suitable for application in a 5.5-in. casing, was designed, manufactured, assembled, and tested. Mineral oil and air were used as the operating media. For given pump outlet valve settings, the pump rotational speeds were set to 200, 250, 300, and 350 rev/min. Gas volume fractions (GVFs) at the pump inlet were varied from 0% to the maximum the current pump design could handle. For each test point, the corresponding pump parameters were measured. Dimensionless performance plots were established for obtaining pump performance at other flow conditions.

The results showed that pump flow rate decreased with increasing differential pressure, typical of positive displacement pumps. At 200 and 350 rev/min, maximum pump delivery is approximately 190 and 330 B/D of oil, respectively, at zero differential pressure. The pump can supply flow against a differential pressure of up to approximately 5.5 psi at 200 rev/min and 15 psi at 350 rev/min. For the 200 to 350 rev/min speed range, volumetric efficiencies varied from 30 to 73%, whereas the electric power input varied from 145 to 191 W. When pumping oil/air mixtures, the current gerotor pump design can handle 15% GVF maximum, at 250, 300, and 350 rev/min. For certain pump outlet pressures, the total fluid flow rates decreased as the GVF increased to 15%. The volumetric efficiencies at 15% GVF varied from 32 to 53% for the 300 to 350 rev/min speed range, whereas the motor electric power input decreased with increasing GVF up to 15%. In conclusion, increasing the pump rotational speed improves the volumetric efficiency and gas-handling capability of the gerotor pump. These observations will aid in the required design optimization to enhance the performance of the future field prototype gerotor pump.

This study presents the capabilities of gerotors as potential artificial lift alternatives to handle liquid and gas/liquid mixtures for boosting applications in oilfield operations. The technology with additional design optimization can be readily integrated into oilfield equipment architecture. The mechanical simplicity of gerotors and their compactness provides a promising artificial lift substitute that may be implemented for downhole or surface production of liquid or gas/liquid mixtures in the oil and gas industry.

The soil-dwelling opportunistic bacterium Bacillus nematocida B16 shows comparatively strong killing activities against a variety of pathogenic nematodes. A bacterial strain CPCC 101271T, isolated from intestines of C. elegans in natural habitats, was found not only to be probiotics for C. elegans but also assist in resisting pathogen B16 infection. The lifespan of Caenorhabditis elegans fed on strain CPCC 101271T was extended by approximately 40% compared with that of worms fed on Escherichia coli OP50. In addition, the colonization of C. elegans by the pathogenic bacterium B. nematocida B16 was inhibited when it was pre-fed with strain CPCC 101271T. Based on a polyphasic taxonomy study including genotypic, chemotaxonomic and phenotypic characteristics, we propose that strain CPCC 101271T represents a novel bacterial species with the name Stenotrophomonas nematodicola sp. nov. and CPCC 101271T as the type strain. Metagenomic sequence analysis of the intestinal microbiota of C. elegans fed with strain CPCC 101271T and then infected with B16 revealed that pre-feeding with CPCC 101271T improved the diversity of intestinal bacteria, while the community structure varied significantly together with the fluctuation of Stenotrophomonas spp. and Bacillus spp. abundance during competition between strain CPCC 101271T and B16. In conclusion, the nematode microbiota strain CPCC 101271T, a novel species of the genus Stenotrophomonas, assisted in its host resistance to the pathogen Bacillus nematocida colonization, so as to act as an intestinal life span-prolonging for C. elegans.

SARS coronavirus 2 (SARS-CoV-2) in the viral spike (S) encoding a SARS-COV-2 SPIKE D614G mutation protein predominate over time in locales revealing the dynamic aspects of its key viral processes where it is found, implying that this change enhances viral transmission. In this paper, we strongly combine topology geometric methods targeting at the atomistic level the protein apparatus of the SARS-COV-2 virus that are simple in machine learning anti-viral characteristics, to propose computer-aided rational drug design strategies efficient in computing docking usage, and powerful enough to achieve very high accuracy levels for this in-silico effort for the generation of the AI-Quantum designed molecule of GisitorviffirnaTM, Roccustyrna_gs1_TM, and Roccustyrna_fr1_TM ligands with Preferred IUPAC Names of (7aR) ‐5‐amino‐N‐[(S) ‐ {2‐[(S) ‐[(E) ‐(amino methylidene) amino](cyano) methyl]hydrazin‐1‐yl} (aziridin‐1‐yl) phosphoryl]‐ 1‐[(2E) ‐2‐ [(fluoromethanimidoyl) imino]acetyl]‐7‐oxo‐1H,7H,7aH‐pyrazolo[4,3‐d]pyrimidine‐3‐carboxamide;N‐{[(2‐amino‐6‐oxo‐6,9‐dihydro‐1H‐purin‐9‐yl) amino]({1‐[5‐({[cyano({1‐[(diamino methylidene) amino] ethenyl}) amino]oxy} methyl) ‐3,4‐dihydroxyoxolan‐2‐yl]‐1H‐1,2,4‐triazol‐3‐yl}formamido) phosphoryl} ‐6‐fluoro‐3,4‐dihydropyrazine ‐2‐carboxamide; [3‐(2‐amino‐5‐sulfanylidene‐1,2,4‐triazolidin‐3‐yl) oxaziridin‐2‐yl]({3‐sulfanylidene‐1,2,4,6 ‐tetraazabicyclo [3.1.0]hexan‐6‐yl}) phosphoroso1‐(3,4,5‐trifluorooxolan‐2‐yl) ‐1H‐1,2,4‐triazole‐3‐carboxylate targeting the COVID-19-SARS-COV-2 SPIKE D614G mutation using Chern-Simons Topology Euclidean Geometric in a Lindenbaum-Tarski generated QSAR automating modeling and Artificial Intelligence-Driven Predictive Neural Networks.

Global warming has become a major threat to life on the earth, and recognizing its impacts can definitely be useful in controlling and mitigating its adverse effects. In this study, time series variations in air temperature indices (frost days, Tmin, Tmax, Tmean, Tminmin, Tmaxmax, Tsoil-min), De Martonne aridity index (IDM) and total precipitation were investigated using a long-term meteorological data (1960–2019) of 31 synoptic stations throughout Iran. The results indicated that more than 94% of the stations had increasing trend in Tmean, in which about 70% were significant at the 0.05 level. The average increase in Tmin was calculated approximately 1.7 times higher than Tmax and also the increase in Tminmin was about 2.5 times higher than Tmaxmax. Our findings showed that, abrupt changes in Tmin and Tmax mostly observed in the 1990s were upward in 87% of all the stations. Increase in annual Tmean at a rate of 0.3 ºC per decade and reduction of 5 mm per decade in total annual precipitation led to decrease in the IDM aridity index by 0.35 per decade in Iran. The intensity of air temperature increase was higher in tropical regions than in cold regions. Trend analysis in the partial series before and after a change point showed that the trends in Tmean before the change point were negative, but turned to positive afterwards in some stations mostly located in the northwestern cold and mountainous regions of the country. Our results revealed that the climate in Iran, in general, has become warmer and drier in the past 60 years and continuation of the current global warming trend will exacerbate this problem in the future.

Published: May 2021

In this paper, the effects of irrigation with different water quality on the soil characteristics of 8 kinds of garden plants were analyzed. The results showed that soil pH (ranging at 7.76–8.73) had no significant difference in different soils compared with the contrast treatment. Under the reclaimed water irrigation, the content of soil total salinity, chloride ions and water soluble sodium in soil of most plants was averagely 160.3%, 83.3% and 67.5% higher than that of tap water, respectively. The influences of reclaimed water irrigation on soil nutrients were changed with the types of plants. The content of soil organic matter and the available potassium showed no significant differences in most plants. Compared with the tap water irrigation, the content of alkaline nitrogen in in 5 plants increased (averagely 25.8%) after 5-year irrigation with reclaimed water. In terms of soil microorganism, the increase of soil microbial population, including bacteria, fungus and Actinomycetes, has been promoted by different levels of reclaimed water irrigation, showing increasing trend with the increasing content of reclaimed water from 0%, 50–100%. Moreover, the number of bacteria and fugus is closely related with the content of soil organic matter, available potassium and effective phosphorus. However, the number of Actinomycetes is determined by the content of available potassium.
Evaluation of MU2net as an Online Secondary Dose Check for MR Guided Radiation Therapy with the Elekta Unity MR Linac
Authors: Baines John , Shoobridge Ariadne
Published: May 2021

During the adaptive workflow associated with MRgRT, a secondary dose calculation is required and MU2net (DOSIsoft, France) is one commercial option. The suitability of MU2net to be used in conjunction with the online Monaco treatment planning system of the Elekta Unity (Elekta AB, Stockholm, Sweden), is evaluated in this work. Monaco and MU2net point doses are compared for various fields on and off axis and at different SSDs. To investigate the comparative effects of attenuation due to the cryostat, couch and posterior coil, measured, MU2net and Monaco dose outputs at the isocentre, as a function of gantry angle, were compared. Point doses for the beams of nine step and shoot IMRT (SSIMRT) test plans (courtesy Elekta) were calculated with Monaco v5.4 and compared to corresponding doses computed with MU2net. In addition, Monaco v5.4 and MU2net point doses were compared for 1552 beams treated on the Unity at our facility. For the on-axis fields investigated the agreement between MU2net and measured data is acceptable. MU2net and Monaco point doses for the Elekta SSIMRT test plans were within ± 5.0 % and ± 6.4 % for beams delivered from gantry zero and at planned beam angles, respectively. For the 1552 beams delivered approximately 80.0 % of MU2net and Monaco point doses agree within ± 5.0 %, therefore it is recommended to correlate MU2net Dose Reference Points (DRPs )with pre and post treatment dosimetry verification. Computational accuracy of MU2net could be enhanced with improved modelling of attenuation due to the couch, cryostat and posterior MR imaging coil.
