Field programmable gate array implementation of an intelligent soft calibration technique for linear variable differential transformers
Authors: Venkata Santhosh Krishnan , Roy Binoy Krishna , Mohanty Preeti
Published: March 2022

Background: Displacement is often used as an indirect indicator for monitoring multiple parameters, i.e. force, velocity, acceleration, and weight, making it an important variable for the measurement and control of processes. Sensors such as Linear Variable Differential Transformers (LVDTs) play a primary role in the design of any displacement measuring instrument. Calibration of an instrument is carried out to produce accurate results from the measuring instrument.

Methods: The objective of this study is to calibrate the output of LVDT by designing a signal conditioning circuit so as to extend the linearity range of the sensor to 100% of the full scale input range, and also allows the measurement technique to adapt to variations in the physical parameters of the LVDT, the supply frequency, and the temperature. An optimized neural network is trained to produce linear and adaptive output from the raw data obtained from LVDT. Optimization is achieved by choosing the best neural network algorithm, number of hidden layers and transfer function of neurons which produce the least mean square error. The optimized neural network algorithm is implemented on a Field Programmable Gate Array (FPGA) chip for testing and validation in real life.

Results: Experimental results show that the proposed technique was able to extend the linearity of LVDT and make the output adaptive for variations in physical parameters of LVDT, supply frequency and temperature.

Conclusions: Accurate measurement of displacement is essential in many process applications, and a good calibration technique is required to produce accurate measurement. The presented calibration technique using optimized neural network algorithms has produced reliable measurements as desired.
Functioning problems associated with conditions with greatest disease burden in South Africa and Zimbabwe: a scoping review protocol
Authors: Charumbira Maria Yvonne , Berner Karina , Louw Quinette A.
Published: March 2022

Background: A notable rise in health-related disability for which evidence-based rehabilitation is beneficial is evident in low-to-middle income countries. This scoping review aims to summarize and synthesize the status of peer-reviewed literature regarding the most common functioning problems associated with health conditions that contribute most to disability in South Africa and Zimbabwe.

Methods: The scoping review will be conducted according to the framework developed by Arksey and O’Malley and corresponding guidance contained in the Joanna Briggs Institute Reviewers’ Manual. Peer-reviewed studies of all designs published from January 2006 onwards will be systematically searched from five databases. Studies reporting on functioning problems (impairments, activity limitations, and participation restrictions) in South African and Zimbabwean adults (>18 years) related to the top 10 health conditions contributing most to years lived with disability in South Africa and Zimbabwe according to the Global Burden of Disease Study 2019 will be included. Two reviewers will screen titles, abstracts, and full texts and chart data. The International Classification of Functioning, Disability and Health (ICF) framework will be used to map identified functioning problems. A narrative approach will be used to synthesize results.

Discussion: This scoping review will provide a comprehensive mapping of functioning problems affecting adults in South Africa and Zimbabwe. Understanding the local rehabilitation needs may be a first step in strengthening primary care rehabilitation in low-resource settings.

Registration: This scoping review protocol was registered with the Open Science Framework (doi: 10.17605/OSF.IO/FJM7W) on 31/12/2020.

Authors: Wincott Matthew , Jefferson Andrew , Dobbie Ian M. , Booth Martin J. , Davis Ilan , Parton Richard M.
Published: March 2022

Commercial fluorescence microscope stands and fully automated XYZt fluorescence imaging systems are generally beyond the limited budgets available for teaching and outreach. We have addressed this problem by developing “Microscopi”, an accessible, affordable, DIY automated imaging system that is built from 3D printed and commodity off-the-shelf hardware, including electro-mechanical, computer and optical components. Our design features automated sample navigation and image capture with a simple web-based graphical user interface, accessible with a tablet or other mobile device. The light path can easily be switched between different imaging modalities. The open source Python-based control software allows the hardware to be driven as an integrated imaging system. Furthermore, the microscope is fully customisable, which also enhances its value as a learning tool. Here, we describe the basic design and demonstrate imaging performance for a range of easily sourced specimens.
Hepatocellular carcinoma in patients with chronic hepatitis C – case study
Authors: Sierpińska Lidia , Jaworski Sebastian
Published: March 2022

Introduction. In Poland, approximately 2% of the total population is infected with hepatitis C virus (HCV) (estimated at 730,000 people). HCV is an etiologic factor of chronic hepatitis C. Hepatitis C is a chronic disease which, when untreated, may lead to cirrhosis of the liver and/or primary liver cancer.  

Objective. The aim of the study was analysis of the personal medical history of a patient with hepatocellular cancer from the aspect of infection with HCV.

Material and Method. A case of a 63-year-old patient is presented with the diagnosis of  hepatocellular carcinoma (HCC) (Carcinoma hepatocellulare), who had undergone the procedure of thermal ablation of the pathological change in the liver. The patient was treated with chemotherapy on a daily basis; anti-HCV antibodies were detected. The research method was a retrospective case study; the technique – analysis of records (internal documentation of the Regional Hospital in Pionki, Poland; while the research tools – medical history with the results of diagnostic tests, the VAS scale and the Glasgow scale.

Results. Based on internal documentation of the hospital a case of a patient was described with severe abdominal pain due to hepatocellular carcinoma, who had been previously diagnosed with HCV infection. Physical examination was presented, as well as epidemiological interview, medical history, the course of diagnostics and treatment of the patient qualified for further ambulatory treatment in the oncology outpatient clinic.

Conclusions. Screening examinations are indicted for an early detection of the presence of anti-HCV antibodies. An early diagnosis of infection with HCV, and implementation of antiviral treatment may prevent the development of hepatocellular carcinoma.
Broadcast Stand-up Comedy and Its Translation
Authors: Raffa Giovanni
Published: March 2022

With the rise of new platforms of media consumptions, aided by new digital technologies, wider audiences and a growing demand for translated materials, new audiovisual transfer modes have surfaced and with them the field of AVT “has grown exponentially, parallel to the production, consumption, interaction with and general interest in audiovisual products” [Chaume 2018: 41]. Stand-up comedy usually thrives as a live form of art. However, digital consumption has allowed comedians to reach a global audience via recording and broadcasting of their performances, and by doing so, it warranted the translation of the genre. In this study, after investigating how the audiovisual format affects comedians’ performances and their subtitling into Italian, I propose new, potentially useful concepts for a translational analysis of broadcast stand-up. Included is a discussion of the presence of audiovisual elements in the streamed specials and an inquiry of the fictionality of the scripted dialogue.
The roles of top management and users in strategic IS planning: a perspective of SMEs
Authors: Ali Raja Haslinda Raja Mohd , Mohamad Rosli , Talib Yurita Yakimin Abdul , Abdullah Akilah
Published: March 2022

Research on the strategic Information Systems (IS) planning is typically concentrated on large firms. However, the outcomes of this research may not be sufficient to adequately apply to Small and Medium Enterprises (SMEs). Responding to the limited body of work in SMEs with respect to strategic IS planning, this research aims to fill the gap in the body of literature. Having limited resources available, financially and technically, strategic IS planning is getting more crucial for SMEs. Prior work suggests that a high level of internal competencies such as IT leadership by the owner or the top management of the firm are important for progressive IT development to take place in SMEs. Having said that IS is getting paramount for firm’s survival to optimize IS effectively, it is incumbent to investigate the factors influencing strategic IS planning amongst the SMEs. This study contributes to research and practice by providing indepth insights into the IS planning processes in SMEs with a particular focus on the roles of top management and users. Researchers can use these results, which are somewhat different from larger organizations, to revise IS planning phases.
Performance measurement of complex project: framework and means supporting management of project-based organizations
Authors: Głodziński Eryk
Published: March 2022

Performance management and measurement enable to improve strategy implementation and increase organizational competitiveness. The literature review and desk research confirm that the design of a performance system is an issue because of the redefinition of project environment conditions and complexity of 4P. The system should be continuously developed during exploitation. Main objectives of the paper are to propose a framework of project performance measurement and a set of measures that could be applied in project-based organizations. The assessment proposal is the result of a literature review and qualitative empirical studies, interviews, and participatory observations. The framework considers performance assessment of the project and its context, including benefits occurring outside the project – on the program, project portfolio, and project-based organization levels – but being the result of project execution. The framework incorporates in project performance assessment the simultaneous and supplementary utilization of quantitative and qualitative measures, financial and non-financial measures that describe various fields of evaluation: finance, production, procurement, product quality, social, marketing of a product, legal, natural environment, client, and other stakeholders’ satisfaction.
Readiness parenting: practices of care by parents of children with chronic kidney disease in Portugal
Authors: Bruno de Sousa Andréa , Goes Ana Rita , Wickström Anette
Published: March 2022

Parents of a child with chronic kidney disease (CKD) must safely perform advanced care and treatment while at the same time allowing the child some freedom and maintaining everyday parenting and family tasks. Drawing on interviews with primary caregivers of children with CKD in Portugal, we examine the context of raising a child with CKD and how the parents practise their parenthood. The study takes inspiration from parenting studies and child studies and explores how good parenthood is constructed. Based on thematic analysis, three core themes emerged: protecting the child, involving the child in their treatment, and transferring responsibility. The transformation of life-limiting circumstances into a life that worked well for both parents and their child represents what we call ‘readiness parenting’. Assessing risks, supporting the child’s autonomy, and relating to social norms required constant vigilance and readjustments as well as negotiations about parental responsibility.
Machine learning enabled multiple illumination quantitative optoacoustic oximetry imaging in humans
Authors: Kirchner Thomas , Jaeger Michael , Frenz Martin
Published: March 2022

Optoacoustic (OA) imaging is a promising modality for quantifying blood oxygen saturation (sO2) in various biomedical applications – in diagnosis, monitoring of organ function, or even tumor treatment planning. We present an accurate and practically feasible real-time capable method for quantitative imaging of sO2 based on combining multispectral (MS) and multiple illumination (MI) OA imaging with learned spectral decoloring (LSD). For this purpose we developed a hybrid real-time MI MS OA imaging setup with ultrasound (US) imaging capability; we trained gradient boosting machines on MI spectrally colored absorbed energy spectra generated by generic Monte Carlo simulations and used the trained models to estimate sO2 on real OA measurements. We validated MI-LSD in silico and on in vivo image sequences of radial arteries and accompanying veins of five healthy human volunteers. We compared the performance of the method to prior LSD work and conventional linear unmixing. MI-LSD provided highly accurate results in silico and consistently plausible results in vivo. This preliminary study shows a potentially high applicability of quantitative OA oximetry imaging, using our method.
Diffraction properties of light with transverse orbital angular momentum
Authors: Huang Shunlin , Wang Peng , Shen Xiong , Liu Jun , Li Ruxin
Published: March 2022

The spatiotemporal optical vortex (STOV) is unique, owing to its phase singularity in the space–time domain, and it can carry transverse orbital angular momentum (OAM). Diffraction is a fundamental wave phenomenon that is well known for conventional light; however, studies on the diffraction of light with transverse OAM are limited. Furthermore, methods that enable the fast detection of STOVs are lacking. Here, we theoretically and experimentally study the diffraction behaviors of STOVs, which are different from those of conventional light. The diffraction patterns of STOV pulses that are diffracted by a grating exhibit multilobe structures with a gap number that corresponds to the topological charge. The diffraction rules of STOVs are also revealed. An approach for the fast detection of STOVs is provided using their special diffraction properties. This method has potential applications in fields that require fast STOV recognition, such as STOV-based optical communications.
Experimental demonstration of continuous-variable measurement-device-independent quantum key distribution over optical fiber
Authors: Tian Yan , Wang Pu , Liu Jianqiang , Du Shanna , Liu Wenyuan , Lu Zhenguo , Wang Xuyang , Li Yongmin
Published: March 2022

Measurement-device-independent quantum key distribution (MDI-QKD) can
remove all side-channel attacks on detectors. In the context of the
dramatic progress of discrete-variable MDI-QKD and twin-field QKD,
owing to the critical challenge of continuous-variable (CV) Bell-state
measurement (BSM) of two remote independent quantum states,
experimental demonstration of CV-MDI-QKD over optical fiber has
remained elusive. To solve this problem, a technology for CV-BSM of
remote independent quantum states is developed that consists of
optical phase locking, phase estimation, real-time phase feedback, and
quadrature remapping in the present work. With this technology, CV-BSM
is accurately implemented, and the first CV-MDI-QKD over optical fiber
is demonstrated, to our knowledge. The achieved secret key rates are
0.43 (0.19) bits per pulse over a 5-km (10-km) optical fiber. Our work
shows that it is feasible to build a CV-MDI-QKD system over optical
fiber. Further, the results pave the way towards realization of a high
secret key rate and low-cost metropolitan MDI-QKD network, and serve
as a stepping stone to a CV quantum repeater.

Published: March 2022

En este artículo se exponen los principales resultados de una investigación que busca comprender las prácticas de crianza en las narrativas generacionales de agentes familiares de niños y niñas vinculados al Hogar Infantil Barrios del Norte de Marsella – Risaralda, Colombia, partiendo de la inquietud respecto a cómo se expresan las prácticas de crianza en las narrativas de agentes familiares, las relaciones entre estas, las prácticas institucionales y los contextos de vulnerabili-dad de las familias. En este sentido, se presentan las tendencias teóricas expresas en metáforas y narrativas pretendiendo argumentar los contextos de vulnerabilidad, así como las rupturas y desplazamientos teóricos en dos regularidades halladas en la investigación: la dimensión material, social e institucional, por una parte, y la dimensión afectiva, ética y política, por la otra. La unidad de análisis se basó en las narrativas de seis agentes familiares de dos generaciones y tres agentes institucionales. Se utilizaron narrativas y entrevistas semiestructuradas; en cuanto al estudio de los datos se realizó un análisis estructural cualitativo en busca de una comprensión de relaciones de significación y construcción de sentidos frente a la crianza. Emerge, así, la categoría agencia política en las familias para construir procesos, ambientes y escenarios hacia la calidad de vida, comprendiendo no solo los bienes y servicios a los que tienen acceso para satisfacer necesidades de carácter material y social, sino también al grado de libertad con el que se elige el estilo y modo de vida que más se valora, las prácticas sociales y espacios de participación política, las actividades laborales y cotidianas y la seguridad social a lo largo del curso de vida en las relaciones de crianza.
Ewentualna przydatność procedur uniwersalnych w pracy z grupami podwyższonego ryzyka. Na przykładzie recepcji programu profilaktycznego „Smak życia, czyli debata o dopalaczach”
Authors: Wojcieszek Krzysztof A.
Published: March 2022

Researchers of the behavior of adolescents from the so-called high-risk groups suggest that due to the high level of problem behaviors (e.g. drinking alcohol, smoking, drug use, violence) the most appropriate preventive work is the harm reduction approach, especially in the case of borderline behaviors such as alcohol use (Pisarska, Bobrowski, Greń, Ostaszewski, 2019: 343). Applying this type of strategy to illegal behavior such as drug use, especially NPS (the so-called legal highs) seems to be a bit more problematic.

Meanwhile, the results of research on the reception (process evaluation) of the “Taste of Life Debate” preventive program scenario indicate that selected universal procedures, intended for young people with an average level of risk, can be successfully used in work with young people at risk, as long as they relate to behavior that is not normative in the social sense (such as using NPS). The work is a short comparison of evaluation results in the universal group and in the high-risk group.
Impact of heat stress on foliar biogenic volatile organic compound emission and gene expression in tomato (Solanum lycopersicum) seedlings
Authors: Nagalingam Sanjeevi , Seco Roger , Musaev Kirill , Basu Chhandak , Kim Saewung , Guenther Alex
Published: March 2022

We present foliar biogenic volatile organic compound (BVOC) emission data from 24-h heat-stressed tomato (Solanum lycopersicum) seedlings including speciated monoterpenes and sesquiterpenes and high time-resolution measurements of methyl salicylate and total monoterpenes. The median total monoterpene and total sesquiterpene emission rates at 30°C were 18.5 and 0.172 pmol m–2 s–1, respectively, which falls within the negligible emission category of previous studies. However, initial heat exposure (39°C or 42°C) increased the emissions of approximately half of the targeted compounds beyond what was predicted by current BVOC emission temperature response algorithms. The enhanced emissions were not always sustained for the entire duration of the heat stress and some plants exhibited a delayed monoterpene response, where emissions peaked toward the end of the heat treatment. Methyl salicylate, a known stress marker, responded differently to the heat stress than most of the other compounds. Heat stress increased methyl salicylate emissions in some plants (at least initially), but in others, emissions declined or did not change significantly. There was no significant correlation between the magnitude of gene expression and emission induction of monoterpenes or methyl salicylate. Furthermore, the emitted monoterpenes did not exhibit any apparent light-dependent behavior, which suggests that these monoterpene stress emissions mostly originated from light-independent foliar storage pools and not from increased de novo production. In contrast, methyl salicylate emissions appear to have contributions from both de novo synthesis and stored pools, as they showed both enzyme-controlled (i.e., light-dependent) and light-independent behaviors. Analyses of the foliar essential oils demonstrate that most of the emitted BVOCs were also present in stored pools. The pool sizes were generally large enough to sustain unstressed emission levels for days to months, and even years for some compounds. However, heat-induced emission enhancement can diminish the pool sizes of some BVOCs, which could decrease subsequent emissions.
Use of HEAVEN criteria for predicting difficult intubation in the emergency department
Authors: Tan Nin Ern , Yoong Khadijah Poh Yuen , Yahya Hj. Mohammad Fadhly
Published: March 2022

Objective Most airway prediction tools only consider anatomical factors. The HEAVEN criteria incorporate both anatomical and physiological elements, but have never been studied in the emergency department. This study aimed to evaluate the association between HEAVEN criteria and intubation difficulty.Methods We conducted a prospective cross-sectional study from April 1, 2020 to January 31, 2021 in the emergency department of a tertiary public hospital. All patients requiring rapid-sequence or delayed-sequence intubation were included. Patients intubated during cardiopulmonary resuscitation were excluded. We enrolled 174 patients. Study endpoints were first pass success and intubation complications.Results The presence of any HEAVEN criteria was associated with a decrease in the first pass success rate (odds ratio [OR], 0.10; 95% confidence interval [CI], 0.02–0.43; P < 0.01). The anatomical challenge was the only criterion associated with first pass sucess (OR, 0.13; 95% CI, 0.05– 0.29; P < 0.01), whilst other criteria (hypoxemia, extremes of size, vomit/blood/fluid, exsanguination, and neck mobility) were not (P > 0.05). All anatomical factor criteria were associated with difficult airway view (P < 0.05). Intubation complications occurred more in the presence of hypoxemia (OR, 7.44; 95% CI, 2.82–19.63; P < 0.01) and vomit/blood/fluid (OR, 5.55; 95% CI, 2.39–12.92; P < 0.01).Conclusion Anatomical challenge in HEAVEN criteria can predict first pass success. All anatomical factors in HEAVEN criteria could predict difficult airway view and peri-intubation hypoxemia could be used to anticipate intubation complications. More validation studies are still needed to evaluate the use of HEAVEN criteria as a predictor tool for difficult airway.

Objective The national health systems are currently facing the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. We assessed the efficacy of outpatient management for patients with SARS-CoV-2 related pneumonia at risk of progression after discharge from the emergency department.Methods This was a single-center prospective study. We enrolled patients with confirmed SARS-CoV-2 pneumonia, without hypoxemic respiratory failure, and at least one of the following: age ≥65 years or the presence of relevant comorbidities or pneumonia extension >25% on high resolution computed tomography. Patients with pneumonia extension >50% were excluded. An ambulatory visit was performed after at least 48 hours, when patients were either discharged, admitted, or deferred for a further visit. As a control, we evaluated a comparable historical cohort of hospitalized patients.Results A total of 84 patients were enrolled (51 male patients; mean age, 62.8 years). Two-thirds of the patients had at least one comorbidity and 41.6% had a lung involvement >25% on high resolution computed tomography; the mean duration of symptoms was 8.0±3.0 days, and the mean PaO2/FiO2 ratio was 357.5±38.6. At the end of the follow-up period, 69 patients had been discharged, and 15 were hospitalized (mean stay of 6 days). Older age and higher National Early Warning Score 2 were significant predictors of hospitalization at the first follow-up visit. One hospitalized patient died of septic shock. In the control group, the mean hospital stay was 8 days.Conclusion Adopting a “discharge and early revaluation” strategy appears to be safe, feasible, and may optimize hospital resources during the SARS-CoV-2 pandemic.
A influência da fiscalidade sobre a contabilidade a partir do julgamento dos contabilistas certificados portugueses
Authors: Pereira Sofia , Albuquerque Fábio
Published: March 2022

este artigo tem como objetivo identificar se, em Portugal, a tomada de decisão em matéria de contabilidade e relato financeiro encontra-se influenciada por critérios de ordem fiscal, em detrimento de critérios económicos. O estudo revela-se oportuno na medida em que o atual normativo contabilístico em Portugal, baseado no internacional, encontra-se em vigor há mais de dez anos. Para a realização do estudo, foi conduzido um questionário aos contabilistas certificados inscritos na Ordem dos Contabilistas Certificados com registo ativo, obtendo-se um total de 406 respostas. Os resultados obtidos possibilitaram confirmar que, mesmo com a adoção do atual normativo contabilístico, francamente baseado no normativo internacional emanado do International Accounting Standards Board, os profissionais de contabilidade privilegiam os critérios fiscais na definição de políticas contabilísticas em distintas áreas. Tais resultados apresentam-se consistentes mesmo quando os resultados são analisados em função de distintos critérios de classificação da amostra. Espera-se que os resultados deste estudo contribuam para a discussão em torno da influência da fiscalidade sobre a contabilidade e o relato financeiro, tendo em conta o ambiente de avançado estágio de harmonização e convergência internacionais onde Portugal se encontra inserido.

Published: March 2022

a presente pesquisa teve por objetivo verificar as relações entre a discriminação percebida pelos consumidores lgbtqia+ e as consequências emocionais (frustração e desamparo) do processo de consumo discriminatório. A investigação se justifica à medida que apresenta um avanço na literatura acerca da discriminação percebida pelo consumidor, pois inclui uma nova perspectiva. Ademais, há escassez de estudos brasileiros que abarquem a temática da discriminação percebida pelo público lgbtqia+, cenário também percebido no âmbito mundial. O delineamento metodológico foi quantitativo, de levantamento online, com amostragem não probabilística junto a 210 participantes do Brasil. Os resultados evidenciam a percepção classificada como baixa ou de nenhuma intensidade de discriminação explícita e de discriminação no atendimento, bem como classifica em média, baixa ou nenhuma intensidade percebida de discriminação sutil. Os resultados mostram que há correlação média com o sentimento de frustração e desamparo dos consumidores, porém não é possível afirmar que a discriminação induz à frustração e ao desamparo. O constructo com maior intensidade de discriminação percebida está contemplado na dimensão de discriminação em nível do atendimento. O trabalho revela as implicações práticas e as possibilidades de estudos futuros no âmbito da discriminação no consumo.

Published: March 2022

El principal objetivo fue comparar los efectos de una sesión HIIT de 35 minutos, en modalidad virtual y presencial, en los estados anímicos y en el esfuerzo percibido en personas con sobrepeso. Se reclutaron un total de 13 personas (5 hombres y 8 mujeres) con una edad promedio de 37.85 ± 13.20 años (rango, 17 y 60 años) los cuales fueron asignados a cada una de las tres condiciones de manera aleatoria (control, entrenamiento presencial y entrenamiento virtual). Previo a, e inmediatamente después de cada una de las intervenciones se aplicó el test POMS para medir los estados anímicos. Con lo que respecta al esfuerzo percibido (EP), su medición se llevó a cabo finalizado cada uno de los ejercicios HIIT (no se evaluó durante el calentamiento y el retorno a la calma). Al aplicar un ANOVA de 2 vías de medidas repetidas (condición [3] x medición [2]) se encontró que tanto la tensión como el vigor después de haber aplicado el tratamiento presencial presentaron un aumento significativo, además la tensión aumentó en la sesión virtual. Por su parte, los valores de EP reportados en las mediciones de las sesiones presencial y virtual estuvieron por encima de lo sugerido en la literatura. En conclusión, una sesión de HIIT para personas con sobrepeso de manera presencial o virtual presenta resultados similares en los estados de ánimo, excepto el vigor, el cual incrementa solo en la condición presencial, las otras variables mostraron un comportamiento similar.
Arbuscular mycorrhizal fungi promote early flowering and prolong flowering in Antirrhinum majus L. by regulating endogenous hormone balance under field-planting conditions

Published: March 2022

It is well documented that arbuscular mycorrhizal fungi (AMF) affect growth and nutrient absorption in host plants under pot conditions. However, their effects on reproductive growth in ornamental plants under field conditions are unknown. Our study evaluated the effects of AMF on flowering and physiological traits in snapdragon (Antirrhinum majus) under greenhouse field conditions. Seedlings were inoculated with Funneliformis mosseae (Nicolson & Gerd.) and without as controls. Results showed that AMF inoculation significantly increased plant height, stem diameter, phosphorus, and soluble protein; decreased soluble sugar; and had no effect on total nitrogen, carbon, and potassium. AMF colonization increased concentrations of abscisic acid (ABA), indol-3-acetic acid (IAA), gibberellin (GA3), and zeatin riboside (ZR); increased the ZR/IAA ratio; and reduced ABA/GA3 and ABA/IAA+GA3+ZR ratios. AMF advanced flowering by five days and prolonged flowering by 13 days. Our study showed that AMF can promote flowering and prolong flowering in snapdragon, which may be due to the improvement of endogenous hormone equilibrium.

Drought stress is significant abiotic stress that limits crop growth and productivity across the globe. The intensity of drought stress continuously rises due to rapid climate change. Drought-induced alterations in physiological and bio-chemical processes by generating membrane dis-stability, oxidative stress, nutritional imbalance and leading to substantial reduction in growth and productivity. Plants accumulate various osmolytes that protect themselves from abiotic stresses' harmful effects. Trehalose (Tre) is a non-reducing sugar found in multiple microbes ranging from bacteria to yeast and in plants and it possesses an excellent ability to improve drought tolerance. Trehalose appreciably enhanced the plant growth, and counter the drought induced damages by maintaining cellular membranes, plant water relations, stomatal regulation, photosynthetic activities, nutrient uptake, osmolyte accumulation, activating stress proteins and detoxifying the reactive oxygen species (ROS) by strengthening the anti-oxidant system. Therefore, it is essential to understand the mechanism of exogenous and endogenous Tre in mitigating the drought-induced damages and to identify the potential research questions that must be answered in the future. Therefore, to better appraise the potential benefits of Tre in drought tolerance in this review, we discussed the diverse physiological and molecular mechanisms regulated by Tre under drought stress. We have a complete and updated picture on this topic to orientate future research directions on this topic.
Identifying strawberry DOF family transcription factors and their expressions in response to crown rot
Authors: LUO Chun , HU Yuyang , SHU Bo
Published: March 2022

Crown rot is one of the most destructive diseases of cultivated strawberry. The DOF family transcription factors, which involved in biotic stress, has not been studied in responding to strawberry crown rot. In this study, the DOFs of Fragaria × ananassa, F. iinumae, F. nilgerrensis, F. viridis, and F. vesca were characterized. One hundred and eighteen FaDOFs, twenty-two FiDOFs, twenty-three FnDOFs, twenty-five FviDOFs and thirty-seven FvDOFs were identified. Gene cluster analysis showed nearly seventy segmental duplication and seventeen tandem duplications for DOF family expansion in octaploid strawberry. In addition, 59 FaDOFs showed syntenic relationships with 32 AtDOFs, which were located on all F.×ananassa chromosomes except Fvb4-1 and Fvb4-2. Except for five DOFs of diploid strawberries had syntenic relationships to one FaDOF, most of them corresponded to multiple FaDOFs. Gene expression analysis revealed that 107 FaDOFs were expressed in crown, and most of them were downregulated by crown rot, while some FaDOFs such as FaDOF107, 12, 82, 91, 90 and 101 were upregulated, whose regulation was not always consistent with the cis-elements in their promoters. Together, these results provided a basis for further functional studies of the FaDOFs.

Broad bean mottle virus (BBMV) infects a wide range of hosts, resulting in significant production reductions. The lack of adequate and effective control methods involves implementing novel BBMV control strategies. Herein, we demonstrate the effect of different potassium concentrations (20, 40, and 60 mM) against BBMV in broad bean plants. Potassium could control BBMV infection in broad bean by inhibiting the virus. In addition, infection with BBMV caused a significant decrease in morphological criteria, SPDA, photosynthetic characteristics, phytohormones, and mineral content in broad bean leaves compared to control plants. The levels of reactive oxygen species (ROS) (hydrogen peroxide, hydroxyl radical, and oxygen anion) and ROS scavenging enzymes (catalase, superoxide dismutase, peroxidase, phenylaniline ammonia-lyase, chitinase, and 1,3 - glucanase) increased significantly in plants inoculated with BBMV alone or in the presence of K+. In addition, proline and phenolic compounds increased significantly after being infected with BBMV. In conclusion, treatment with a high potassium concentration (60 mM) alleviates the adverse effect of BBMV on broad bean plants by boosting secondary metabolites, phytohormones, and enzymatic antioxidants.

Sumac is the wine-colored ground spice, belonging to the cashew family (Anacardiaceae). The most important components of sumac ethanolic extract obtained from sumac are Trans-Caryophyllene, diethyl ester, Butanedioic acid, Cembrene, 1,7-Nonadien-4-ol,4,8-dimethyl, Malate, Palmitate, 9-Octadecenoic acid, Ethyl Linoleic acid, Phytol and Ethyl Linoleate. In the Middle East, sumac is used as a spice and is extensively consumed with Kebabs and grilled meats. It is traditionally used by native Indians of North America in the treatments of bacterial diseases, such as syphilis, gonorrhea, gangrene and dysentery. In traditional medicine of Middle Eastern countries, it has been used for cholesterol reduction and sweating because it has shown antibacterial, hypoglycemic activities and even antioxidant properties due to the presence of tannin fractions in both of their fruits and leaves. The most important health benefits of sumac are reduced cholesterol, balance blood sugar levels, rich in antioxidants, calms muscle aches, reduce the chance of bone depletion, and it can help in the fight against cancer. In this review article all relevant papers of different scholars and researchers were searched in Google Scholar, Science Direct, Scopus and PubMed. Sumac has numerous health benefits and important pharmacological activities, and it can be considered as a valuable source of nutraceuticals, and an efficient natural drug.

Abstract The objective was to evaluate the internal quality of eggs from commercial laying hens and free-range hens subjected to different storage periods and temperatures. For the experiment, 280 eggs were randomly distributed into different treatments, adopting a completely randomized design, in a 2 x 7 factorial arrangement of two temperatures, seven storage periods, totaling 14 treatments with 10 replications. The treatments consisted of two storage conditions: under refrigeration (6 ± 1.0ºC) and at room temperature (26.6 ± 1.0ºC). Eggs were analyzed for 30 days, with evaluations in different storage periods (0, 5, 10, 15, 20, 25 and 30 days). For each storage condition, 140 eggs were separated, 70 commercial eggs and 70 free-range eggs. There was a linear increase in egg weight loss, yolk weight, albumen pH, yolk pH, length and width of albumen and yolk of commercial and free-range eggs, as the storage period increased. There was a linear reduction in weight, height and albumen index and in the yolk index of commercial and free-range eggs as the storage period increased, with more pronounced responses for eggs stored at room temperature (P<0.05). Albumen percentage was linearly reduced only for commercial eggs (P<0.05). Eggs kept at room temperature reduce their quality after 15 days of storage, and the storage under refrigeration for 30 days is recommended to preserve the shelf life of the egg for consumption.

As metodologias ativas podem ser entendidas como alternativas pedagógicas que colocam o foco do aprendizado nos estudantes. Com mediação de docentes competentes, os alunos aprendem a partir da descoberta, da investigação e por problemas. Tais metodologias comumente promovem uma maior retenção e compreensão de contéudos ensinados, uma vez que o aprendiz se encontra engajado nas atividades, seja por meio de pesquisa, colaborações em grupo, discussão e resolução de problemas. Este trabalho teve como objetivo verificar a evolução temporal do uso de metodologias ativas, no contexto dos cursos superiores de Engenharia, a partir de um mapeamento sistemático da literatura. A partir de um protocolo de pesquisa devidamente definido, buscou-se verificar quais os principais pesquisadores desta área, sua localização geográfica e quais as metodologias preferidas no contexto destes cursos. A partir dos resultados, foi possível observar que o crescimento do número de publicações científicas sobre metodologias ativas no contexto da Educação em Engenharia, em especial nos últimos cinco anos do período analisado (entre 2015 e 2020). Pode-se notar a realização de pesquisas neste contexto em todos os continentes, com predomínio de estudos liderados por pesquisadores americanos e europeus. Nos estudos mapeados, a sala de aula invertida e a aprendizagem baseada em problemas foram as metodologias mais identificadas. Isso demostra uma maior preocupação dos professores da área em promover atividades com elevado envolvimento, que permitam o desenvolvimento de habilidades e competências pessoais e profissionais, ainda no período de formação.

Hem küresel hem de bölgesel çapta etkilerini gün geçtikçe daha da ağır bir biçimde hissettiren iklim değişikliği, küresel önlemlerin alınmasını gerektirmektedir. Bu anlamda AB Yeşil Mutabakatı (AYM) ve Sürdürülebilir Kalkınma Amaçları (SKA) son yılların en çok yankı uyandıran nitelikli iklim değişikliğini azaltım çağrıları olarak düşünülebilir. Bu nedenle bu iki iklim değişikliği azaltım çağrısının detaylıca incelenmesi ve bu kapsamda yapılabileceklerin iyi anlaşılması gelecek politikaları açısından oldukça önemlidir. Buna dair öneri, uygulama ve önlemlerin birey ve sektörler tarafından benimsenmesi iklim değişikliği azaltım hedefi açısından en önemli adımlardan biri olacaktır. Bu kapsamda bu çalışmada, AB Yeşil Mutabakatı ve Sürdürülebilir Kalkınma Amaçları doğrultusunda yapılabileceklere yönelik enerji, ekonomi, arazi kullanımı ve toprak yönetimi ile tarımsal uygulamalara değinilmiş, Türkiye’nin güncel durumu ile uygulanabilir stratejiler ve yöntemlerle birlikte adil geçiş kavramı detaylıca incelenmiştir. Çalışmada incelenen araştırmalar, AR-GE çalışmalarının desteklenmesi, uygulanabilir nitelikte ekonomik ve çevresel politikaların geliştirilmesi, sektör bazında üretim ve birey bazında tüketim alışkanlıklarının değiştirilmesiyle Türkiye açısından AYM ve SKA ortak amaçlarına ulaşılabileceğini göstermektedir. Bu anlamda Türkiye’nin bu nitelikli iklim değişikliği azaltım çağrıları kapsamında belirleyeceği uygulama planı ile iklim değişikliği etki ve risklerine uyum stratejilerinin başarıya ulaşması da mümkün olabilir.

En Inde, si pendant la dernière décennie les grandes enseignes d’informatique et de pharmaceutique se sont concentrées sur des approches de management privilégiant la réduction des coûts et la gestion optimale du temps, la plupart d’entre elles favorisent aujourd’hui des pratiques professionnelles dont les nouvelles normes sont de « progresser ensemble et pratiquer le self-branding ». Les opérateurs de formations linguistiques pour ces entreprises multinationales se voient aussi obligés de s’aligner sur ce nouveau modus operandi. Ce compte rendu d’expérience explique comment des principes de management ont été intégrés à des principes pédagogiques d’une formation en français sur objectif spécifique animée auprès des traducteurs en anglais-français dans le domaine de la pharmacovigilance.
