Authors: Soleimany Ali , Kavandi Hadiseh , Khalili Naser , Abbasi Ata , Ghaderi Mohsen , Abasi Esmaeil , Hajizadeh Reza
Published: July 2022

Background: Death due to coronary artery disease (CAD) is twice higher in men than women, and older men are more susceptible to the disease. Serum testosterone levels decrease with increasing age. Objectives: In this study, we aim to study the association between serum testosterone levels and Gensini scores in men. Methods: This cross-sectional study was conducted on 60 men above 40 years who had undergone coronary angiography. Thirty of them had normal coronary vessels, and 30 had coronary artery disease. For each group, the Gensini score was calculated. Results: Serum testosterone levels in the CAD group and the control group were 4.04 ± 2.56 and 5.59 ± 2.20 ng/mL, respectively (P < 0.05), and free testosterone levels in the CAD patients and the control groups were 7.32 ± 5.24 and 12.91 ± 3.27 pg/mL respectively (P < 0.001). Sex hormone binding globulin (SHBG) levels in the CAD and the control groups were 28.88 ± 15.30 and 38.2 ± 19.9 nmol/mL, respectively (P = 0.04). Univariate analysis showed a significant association between Gensini score and total and free testosterone levels. The receiver operating characteristic curve (ROC) showed that the cut-off point of 7.97 had a sensitivity of 73.3% and specificity of 90% in predicting a high Gensini score (AUC = 0.799, P < 0.001). Conclusions: Findings of our study demonstrated that serum free testosterone levels have a significant correlation with Gensini score and CAD severity.

Published: July 2022

Background: The nature and extent of changing adherence to COVID-19 preventive health measures are different in various populations. Objectives: The aim of this study was to investigate the intention of changing adherence to COVID-19 preventive health measures (ICA-COVID-19–PHM) after implementation of the COVID-19 vaccination program compared to when they had not received the vaccine. Methods: This cross-sectional study was conducted on 1000 participants in the 18 to 60-year-old group population (Mazandaran Province, Iran). The data were collected by an anonymous online “Google Form” questionnaire. The Pearson correlation coefficient, intra-class correlation coefficient (ICC), and paired t-test were used to evaluate the intention of changing adherence to COVID-19 preventive measures. Results: The correlation coefficient ranged from 0.58 for non-travel to 0.76 for personal hygiene. ICC ranged from 0.68 for non-traveling to 0.86 for personal hygiene and hand/face washing. The results of the paired t-test showed that there was a significant difference between the adherence at the present time and the intention to adhere to preventive protocols after receiving the vaccine. Conclusions: The intention of changing adherence to preventive health measures, such as avoiding travel and crowded places and mask-wearing, had the most reduction.
Playing with Copyright
Authors: Secker Jane , Morrison Chris
Published: July 2022

Copyright education has become an important aspect of librarians’ information literacy and scholarly communications activities. These include providing support and delivering teaching sessions for teaching and professional services colleagues, as well as students, researchers and other library users. Since the Covid-19 pandemic and the shift to online and hybrid teaching, it has become increasingly important for lecturers and teachers to understand how licences and copyright exceptions apply to teaching and learning activities. The need for this has been documented by practitioners and scholars around the world (Hudson and Wragg, 2020; Craig and Tarantino, 2020; Morrison and Secker, 2020).In this paper we will briefly outline the concept of ‘copyright literacy’ as defined by IFLA (2018) and how it has many parallels with teaching other aspects of information literacy. This includes taking a more ‘critical’ approach, where students are encouraged to explore power dynamics within the systems of creation and consumption of information. Copyright education has traditionally been approached in a rather dry, lecture style format. This approach often serves to reinforce the perception of copyright education as the communication of a set of rigid rules to follow. We argue that the creation and use of copyright games, including Copyright the Card Game and The Publishing Trap, has transformed approaches to teaching copyright in recent years and supported a broader, more critical conception of copyright literacy. Both games are licensed as open educational resources and have been adapted and re-used by others in the UK and in other countries around the world. They have also sparked the creation of other copyright games, which are showcased at an annual conference: ICEPOPS – the International Copyright Literacy Event with Playful Opportunities for Practitioners and Scholars.The paper will explore the pedagogic principles behind our games as well as considering the value of games and playfulness when teaching about a subject such as copyright that is known to cause uncertainty and anxiety. We will also reflect on how we adapted both our games for teaching online during the Covid-19 pandemic. Through this process it was important to retain the learning outcomes of the game but also the pedagogical approaches used including the use of teams and point scoring, peer learning, the use of scenarios and of discussion and critical thinking. Finally we will discuss feedback we’ve collected from librarians and others who have played or used our games in their own teaching. We will conclude considering how a critical approach to copyright education aligns with a signature pedagogy of playful learning.
A case report of malignant peripheral nerve sheath tumour of the left thigh and popliteal fossa with lungs, spleen, and brain dissemination related to neurofibromatosis type 1

Published: July 2022

A malignant peripheral nerve sheath tumour (MPNST) is a highly aggressive sarcoma. This disease develops in a number of people with neurofibromatosis type 1 (NF1), which is a common genetic disease. The paper presents a patient with typical manifestations of a malignant tumour of the peripheral nerve sheath, in the form of a large tumour of primary localisation in the distal part of the left thigh and left popliteal fossa and with significant dissemination into the lung parenchyma, which was accompanied by respiratory risk. The first operation of the tumour was done four years earlier, after which the patient did not come for regular check-ups. Nine cycles of chemotherapy were performed by Doxorubicin / Ifosfamide / Mesna protocol with clinical improvement and stabilisation, but without a significant impact on the dynamics of the disease and the overall survival was 14 months. It is of utmost importance to early recognise clinical presentation of the malignant form of this tumour and active supervision of a patient with a benign form by experts. In this way, it is possible to apply the optimal treatment modality in a timely manner.
Acquired hemophilia in patients on oral anticoagulant therapy: Case report
Authors: Ljubičić Jelena
Published: July 2022

Introduction: Acquired hemophilia is a severe, sometimes even fatal condition of impaired coagulation. It most often leads to severe mucocutaneous, gastrointestinal, urinary, and, rarely, intracranial bleeding. This disorder occurs due to the production of antibodies against clotting factor VIII (F VIII), which interfere with its normal function. In laboratory analyses, prolonged activated partial thromboplastin time (aPTT), which cannot be normalized after being mixed with pooled normal plasma, is noticeable. Case report: In this article, the clinical course of the disease is described in a patient with acquired hemophilia, who was treated with oral anticoagulant therapy, and who initially also had prolonged prothrombin time, measured in international normalized ratio (INR) units, which measure how long it takes for a clot to form in a blood sample. Hemorrhagic syndrome was explained by iatrogenic effect. However, since bleeding continued after INR normalization, it was suspected that there was a different cause of hemorrhagic syndrome. The aPTT mixing test was performed (mixing an equal volume of the patient's plasma and normal pooled plasma (NPP) and repeating the aPTT test immediately and after one-hour incubation), after which the aPTT remained prolonged. This proved the presence of coagulation inhibitors, which is why acquired hemophilia was suspected. The patient was referred to a tertiary medical institution for further diagnostics and treatment. Conclusion: The objective of this case report is to show that patients with hemorrhagic syndrome, who are on anticoagulant therapy, may develop hemorrhagic syndrome for a different, non-iatrogenic reason. The purpose of the study is to draw the attention of medical doctors to various causes of hemorrhagic syndrome in patients receiving anticoagulant therapy.

Published: July 2022

Introduction. Antibiotic prophylaxis (AP) in surgery is an important measure that contributes to the prevention of surgical site infection. International and national guidelines provide clear recommendations for the proper implementation of antibiotic prophylaxis. However, many studies indicate poor compliance in many health care centers. Aim: Our study aimed to determine the level of compliance in the application of antibiotic prophylaxis in abdominal surgery with the guidelines. Materials and methods: The retrospective study included all patients which were operated on at the Clinic for Digestive Surgery of the University Clinical Center of Serbia (UCCS), during the period January - March 2019 (270 patients). Medical records provided information about the type of surgery, the choice of antibiotic, the time of application, the route of administration, the need for redosing, the duration of antibiotic prophylaxis administration, as well as the presence of drug allergies. The collected data were analyzed by descriptive and analytical statistics (ch2 test). Results: During the study period, 270 patients were operated on at the Clinic for Digestive Surgery, of whom 227 (84.1%) received antibiotic prophylaxis. Cefazolin, an antibiotic recommended for most abdominal surgeries, was administered to only 17 (6.3%) patients. The majority of patients (64.4%) received antibiotic prophylaxis within 30 minutes of the beginning of surgery. The duration of antibiotic prophylaxis of up to 24 hours after the operation was applied in 13.1% of patients. Conclusion: Compliance with the guidelines was low, while full compliance with the recommendations for antibiotic prophylaxis was achieved only with regards to the route of antibiotic administration.
Minimally invasive thoracoscopic surgery as a diagnostic and therapeutic approach in bilateral pneumothorax in pregnancy caused by lymphangioleiomyomatosis: A case report
Authors: Garabinović Željko , Čolić Nikola , Vasić-Madžarević Jelena , Savić Milan
Published: July 2022

Introduction: Lymphangioleiomyomatosis (LAM) is a rare disease which mainly occurs in women in the generative period, as well as during pregnancy, while only a few individual cases have been described in men. It occurs in sporadic form or is associated with tuberous sclerosis complex. The diagnosis can be made on the basis of high-resolution computed tomography (HRCT) findings, or histopathological analysis is required. Clinical manifestations of the disease include the following: progressive dyspnea on exertion, recurrent pneumothorax, chylothorax, angiomyolipomas and lymphangiomyomas. Case report: A 32-year-old female patient was admitted to our clinic, in her third trimester of pregnancy, after a left-sided pneumothorax was verified on chest X-ray. Initial treatment included needle aspiration, followed by thoracic drainage of the left pleural cavity. Due to the prolonged air leak through the thoracic drain and the advanced stage of the pregnancy, a caesarean section was performed. After delivery, chest X-ray revealed complete right-sided pneumothorax, which required thoracic drainage, as well as an insufficiently reexpanded left lung. HRCT was performed and cystic bullous changes in the lungs were noted; LAM was histopathologically verified through a minimally invasive thoraco-surgical approach, first on the left and then on the right side, while bilateral pneumothorax was surgically treated. Conclusion: Pneumothorax is a common complication of LAM. Due to the high recurrence rate, definitive early surgical intervention should be performed. Current guidelines recommend chemical pleurodesis and surgery for the first pneumothorax. When treating pneumothorax in pregnancy, the appropriate therapeutic procedure should be applied, taking into account the safety of the pregnancy and of the delivery.
Seakeeping Performance of NASA’s Orion Crew Module
Authors: Carrico Todd
Published: July 2022

In the winter of 2008, NASA’s Constellation Program Office initiated a full scale experimental program to quantify the hydrodynamic performance of the Orion Crew Module. The intent of such an experiment was to give real world experience to the DoD recovery forces tasked with recovery of the astronauts and CM after splashdown. The Seakeeping and Marine & Aviation Divisions of the Naval Surface Warfare Center Carderock Division were given the responsibility of performing this task. Over the course of the next year, NSWCCD personnel designed and constructed a full scale ‘boilerplate’ module known as PORT; and tested it off the coast of Kennedy Space Center. Concurrent to the PORT effort, NSWCCD developed seakeeping simulations and conducted a series of ¼ scale model experiments to understand the seakeeping, dynamic stability, and towing aspects of the CM. These experiments were conducted at NSWCCD and at the Littoral Warfare Environment located at the U.S Army’s Aberdeen Proving Grounds. This paper discusses the multi-year NSWCCD technological effort. Specifically, it showcases the testing aspects of this unique program. It also demonstrates the strong correlation between model experiment, simulation, and full scale trial data.
The Operation of Force-controlled Absorbing Wave Machines
Authors: Spinneken Johannes , Swan Chris
Published: July 2022

In the near future, the wavemaking facilities at the Naval Surface Warfare Center, Carderock Division (NSWCCD) will be equipped with actively absorbing, force-feedback controlled wavemakers. The purpose of the present study is to demonstrate the successful application of a novel theoretical transfer function appropriate to the operation of such wave machines. This transfer function has been formulated in an earlier study by the same authors and models the wave machine as a coupled hydrodynamic system.

In modelling the wave machine’s dynamic behaviour, the hydrodynamic coefficients are accounted for in an analytical fashion; such an approach being supported by the relatively simple geometries of the most common wave boards. Given the resulting theoretical transfer function, which directly relates the force demand signal to the wave field in the tank, the latter may be evaluated before the experiment. Coupled with a pseudo-random wave generation or synthesis technique, the theoretical model enables the numerical prediction of the surface profile in the facility.

With the relevant theory having being established, the experimental data presented herein is complementary to the earlier work. In particular, the simultaneous generation and absorption in a double ended wave flume is discussed. This includes both the generation of regular wave trains as well as irregular or random seas. The work presented herein is limited to the generation and absorption of uni-directional waves in wave flumes. However, the theoretical and practical aspects of multi-directional wave generation in force control have now been formulated and reference to this separate study is made.
Electronic Instrumentation For Distributed Pressure Measurements On Model Tests

Published: July 2022

Electronic instrumentation applied to small scale tests in ocean basins demands a very specific design, turning the use of commercial equipment a complex and challenging task to adapt these general purpose devices for specific needs. Under this perspective, the aim of the study is to discuss an experimental methodology to get the maximum wave impact pressure due to the slamming occurrence on a floating structure. This was demanded in a model test in the wave basin of LabOceano, COPPE/ UFRJ. The pressure instrumentation was based on a sensor’s grid measurement system. This allowed covering a larger area of the impact region. Due to the necessity of adapting the pressure sensor to an underwater use, all the calibration and mounting procedures, together with the difficulties and solutions will be presented. The importance of the results obtained motivates new tests and the improvement of the calibration and water proofing procedures. This kind of solution may be useful for other kinds of near water surface pressure measurements in ocean basins and towing tanks. The dynamic calibration procedures are very important for future studies. The events to be monitored can sometimes have a high frequency response. This will also be discussed.
Test Design for Towing Tank Tests of Large Models
Authors: Irvine Martin , Fu Thomas C.
Published: July 2022

Current research areas in naval design and hydrodynamics are pushing the size of experimental models to larger scales to reduce scale effects and due to the increased size of the concepts. These larger models require special test design considerations for testing in existing facilities. Indoor/outdoor use models can be carefully designed for testing in both environments and to ensure sufficient powering. Articulated models introduce additional degrees-of-freedom, that require installation configurations using pitch and heave mounts (grasshoppers) to compensate. Large models encounter higher forces that require either more robust tow posts and/or grasshoppers to alleviate the encountered hydrodynamic forces and follow wave impacts.
Frequency Dependence of Hydrodynamic Coefficients in Roll
Authors: Judge Carolyn Q.
Published: July 2022

A series of tow tank tests were performed to determine whether the added mass moment of inertia in roll and damping roll coefficient for a planing hull are frequency dependent. The model was forced in roll while running at planing speeds. The model was free to heave and pitch, but restrained in sway and yaw. The roll motion, pitch motion, speed and the force required for the roll oscillation where recorded. From these data, the roll stiffness coefficient, the damping roll coefficient, and the added mass moment of inertia in roll were calculated at various oscillation frequencies. The roll damping showed no frequency dependence. The added mass moment of inertia showed no frequency dependence at high frequencies. At low frequencies the added inertia appeared dependent on both frequency and speed. However, analysis shows that the added inertia calculation is highly sensitive to the error in the measured forcing moment amplitude at low frequency. Therefore, to accurately determine the coefficients at low frequencies, there must be tighter error control of the forcing moment measurements or an increased number of test runs.

O objetivo deste estudo foi investigar o uso da informação contábil na gestão das micros e pequenas empresas do município de Poção, localizado no Estado de Pernambuco, Brasil. Ao estabelecer esse objetivo, a pesquisa pretende contribuir com o estudo do uso da informação contábil na gestão das micro e pequenas empresas. A pesquisa se caracteriza como descritiva, de abordagem quantitativa, e envolveu pesquisa de campo com aplicação de questionário aos micros e pequenos empresários do município de Poção. Os resultados revelaram, dentre outros aspectos, que a maioria dos micros e pequenos empresários que possuem contador em sua empresa utiliza a informação contábil para tomada de decisão. Por outro lado, apesar de 87,9% dos respondentes reconhecerem a importância das informações contábeis para a gestão, 36,4% não possuem contador. E, embora os gestores das micros e pequenas empresas do município de Poção considerem as informações contábeis importantes, seu uso no processo decisório não ocorre de forma ampla, dado que seus gestores geralmente confiam mais na própria experiência e, em alguns casos, até mesmo na intuição, deixando de usufruir dos benefícios que essas informações podem trazer para a gestão da empresa.

The teaching-learning process of the saxophone in Spain has enjoyed an exponential and positive change in recent decades, which has been reflected both in the quality of the saxophonists and in the diffusion of the instrument itself. The aim of this study is to explore teachers' opinions about the saxophone and its formal teaching in the Professional Conservatories of Music in Spain, as well as their vision of the future. The methodology used was non-experimental and exploratory, with the survey as the research instrument. The sample chosen was n73 from a population of 220 saxophone teachers, with simple unweighted allocation, with a confidence level of 90% (two sigma) and P=Q, with a maximum possible error of ±6% for the whole sample and using simple random sampling. The variables analyzed were repertoire and technique, teaching-learning process, learning outcomes, material resources and educational policies. The results show: 1) educational policies are a fundamental support for the development of saxophone education in Spain, 2) a diversification of curricula, methods and saxophone repertoire and contents is needed to design a creative access model to the labor market, 3) the teacher is the best prescriber in the regulated teaching of the saxophone

Ignorancia culpable: una perspectiva internalista a partir de creencias disposicionales para el contexto tecnológico
Authors: González-Martín Joshua Alexander
Published: July 2022

La ignorancia es, a menudo, una excusa válida que disculpa una acción incorrecta. Pero autores como William FitzPatrick argumentaron que la ignorancia es culpable si se podía esperar razonablemente que el agente tomara medidas que la hubieran corregido o evitado, dadas sus capacidades y las oportunidades que brinda el contexto, pero no lo hizo por vicios como la pereza, la indiferencia, el desdén, etc. La ignorancia culpable sigue estando presente en el debate y, en los últimos tiempos, se ha vuelto más acuciante con el problema de la responsabilidad tecnológica. En este trabajo se adopta una perspectiva internalista de la ignorancia culpable, para analizar una forma de distribución de la culpabilidad, en el contexto tecnológico, basada en creencias disposicionales. Así, se encuentran dos tipos de responsabilidad. Al examinar las implicaciones de la ignorancia culpable, nos damos cuenta de que podemos responder a la idea inequívoca de que un ingeniero es moral y epistémicamente responsable de ciertos hechos.

“Que nos devuelvan la belleza": propuestas postpornográficas de María Cañas
Authors: Álvarez Marta
Published: July 2022

Este trabajo estudia el uso de la imagen pornográfica en la obra de María Cañas (1972), una de las grandes figuras del apropiacionismo en el cine experimental español. Partiendo de los análisis de la teoría y crítica fílmica feminista, así como de filósofxs y sociológxs que aportan una perspectiva de género, plantearemos si las películas de la autodenominada Archivera de Sevilla — en particular El perfecto cerdo (2005), La cosa nuestra (2006), Down with Reality (2006), Fuera de serie (2012), Sé villana. La Sevilla del diablo (2013), La mano que trina (2015), Expo’Lio 92 (2017), La cosa vuestra (2018) y Padre no nuestro (2019)—, más allá de las imágenes robadas a la pornografía industrial, pueden entenderse como ejemplos de una postpornografía que cuestiona las representaciones y las estructuras socioeconómicas que las determinan, denunciando un capitalismo basado en la violencia y proponiendo un feminismo antiespecista que pasa por la reapropiación de los cuerpos vulnerables.
'Un día más con vida' (Raúl de la Fuente, Damian Nenow, 2018): una relectura épica de Kapuscinski desde el cine de animación
Authors: Padilla Aguilera Tania
Published: July 2022

Un día más con vida (2018) es una coproducción europea promovida por el español Raúl de la Fuente que adapta el texto homónimo de Ryszard Kapuscinski, publicado en 1976. El filme aúna los géneros de la animación y el documental combinando imágenes reales con recreaciones realizadas por ordenador. Aunque el guion se apoya en el texto del reportero polaco, la complejidad genérica de este hace que su trasvase cinematográfico sea particularmente complicado. La hibridación entre crónica periodística y autobiografía planteada por Kapu?ci?ski se convierte en manos de los realizadores en una suerte de hagiografía del personaje. En este sentido, se produce una relectura de su mensaje desde unas claves ideológicas más marcadas que, sin embargo, adoptan formalmente el lenguaje hollywoodiense del blockbuster. Esta investigación propone un cotejo entre ambas obras para desentrañar sus principales puntos de divergencia. Entre otros aspectos, ocuparán el desarrollo de nuestro trabajo la reconstrucción del perfil autoral de Kapu?ci?ski, el rastreo de las principales influencias en el proceso de transmedialización, el examen de los rasgos de la épica clásica en la configuración de una estética próxima a la del cómic y el videojuego, y el análisis de la subversión ideológica que se produce en el trasvase realizado.

Prioritizing Components of a Dyadic Physical Activity Intervention for People With Moderate to Severe Multiple Sclerosis and Their Care Partners: A Modified e-Delphi Study
Authors: Fakolade Afolasade , McKenna Odessa , Kamel Rachel , Freedman Mark S. , Finlayson Marcia , Latimer-Cheung Amy E. , Pilutti Lara A.
Published: July 2022

BACKGROUND

People with moderate to severe multiple sclerosis (MS) and their family care partners do not engage in sufficient physical activity (PA) for health benefits. Dyadic PA interventions need to be developed to benefit each individual and the dyad. The objective of this study was to engage expert stakeholders in prioritizing and refining key intervention content, delivery methods, and the practical/logistical aspects of a dyadic PA intervention for persons with MS and their care partners.

METHODS

Thirty-two stakeholders (14 clinicians, 11 people with MS, 5 MS care partners, and 2 representatives of organizations that provide support services for people with MS and/or MS care partners) completed 2 rounds of a modified e-Delphi survey. In round 1, participants rated items across 3 domains: key intervention content (n = 8), delivery methods (n = 9), and practical/logistical aspects (n = 4). Participants contributed additional ideas about these domains, which were incorporated into round 2. Items that did not reach consensus in round 1 were forwarded to round 2 for rerating. Data were analyzed using descriptive statistics and content analysis.

RESULTS

A 24-item list of recommendations was generated, including ensuring that presentation of the intervention content encouraged lifestyle activities in addition to exercise, using videoconferencing rather than teleconferencing as a delivery platform, and stressing the importance of flexibility during the support calls.

CONCLUSIONS

Feedback will be used to improve the quality of the intervention. The next step in this line of research involves evaluating the refined intervention in a pilot feasibility trial.

Published: July 2022

SARS-CoV-2 remains a worldwide emergency. While vaccines have been approved and are widely administered, there is an ongoing debate whether children should be vaccinated or prioritized for vaccination. Therefore, in order to mitigate the spread of more transmissible SARS-CoV-2 variants among children, the use of non-pharmaceutical interventions is still warranted. We investigate the impact of different testing strategies on the SARS-CoV-2 infection dynamics in a primary school environment, using an individual-based modelling approach. Specifically, we consider three testing strategies: (1) symptomatic isolation, where we test symptomatic individuals and isolate them when they test positive, (2) reactive screening, where a class is screened once one symptomatic individual was identified, and (3) repetitive screening, where the school in its entirety is screened on regular time intervals. Through this analysis, we demonstrate that repetitive testing strategies can significantly reduce the attack rate in schools, contrary to a reactive screening or a symptomatic isolation approach. However, when a repetitive testing strategy is in place, more cases will be detected and class and school closures are more easily triggered, leading to a higher number of school days lost per child. While maintaining the epidemic under control with a repetitive testing strategy, we show that absenteeism can be reduced by relaxing class and school closure thresholds.

Published: July 2022

Background:

De novo mutations underlie individually rare but collectively common pediatric congenital disorders. Some of these mutations can also be detected in tissues and from cells in a parent, where their abundance and tissue distribution can be measured. We previously reported that a subset of these mutations is detectable in sperm from the father, predicted to impact the health of offspring.

Methods:

As a cohort study, in three independent couples undergoing in vitro fertilization, we first identified male gonadal mosaicism through deep whole genome sequencing. We then confirmed variants and assessed their transmission to preimplantation blastocysts (32 total) through targeted ultra-deep genotyping.

Results:

Across 55 gonadal mosaic variants, 15 were transmitted to blastocysts for a total of 19 transmission events. This represented an overall predictable but slight undertransmission based upon the measured mutational abundance in sperm. We replicated this conclusion in an independent, previously published family-based cohort.

Conclusions:

Unbiased preimplantation genetic testing for gonadal mosaicism may represent a feasible approach to reduce the transmission of potentially harmful de novo mutations. This—in turn—could help to reduce their impact on miscarriages and pediatric disease.

Droughts are the most expensive natural disasters on the planet. As a result of climate change and human activities, the incidence and impact of drought have grown in China. Timely and effective monitoring of drought is crucial for water resource management, drought mitigation, and national food security. In this study, we constructed a comprehensive drought index (YCDI) suitable for the Yellow River Basin using principal component analysis and the entropy weight-AHP method, which integrated a standardized precipitation evapotranspiration index (SPEI), self-calibrating Palmer drought severity index (scPDSI), vegetation condition index (VCI), and standardized water storage index (SWSI). SWSI is calculated by the terrestrial water storage anomaly (TWSA), which can more comprehensively reflect the impact of surface water resources on drought (as compared with soil moisture-based indexes). The study results showed that: (1) compared with single drought index, YCDI has stronger ability to monitor drought process. In terms of time scale and drought degree, the monitoring results based on YCDI were similar with data presented in the China Flood and Drought Bulletin and Meteorological Drought Yearbook, reaching ~87% and ~69%, respectively. The correlation between drought intensity and crop harvest area was 0.56. (2) By the combined analysis of the Mann-Kendall test and Moving T test, it was found that the abrupt change of YCDI index at the time of 2009, mainly due to the precipitation in 2009 reached the lowest value in the past 30 years in northern China and extreme high temperature weather. (3) The YCDI of Henan and Shandong provinces in the middle and lower reaches of the basin decreased more significantly, with the maximum value reaching 0.097/yr, while the index in the upper reaches showed an increasing trend with the maximum rate of 0.096/yr. (4) The frequency of mild drought, moderate drought, severe drought and extreme drought in the Yellow River basin during the study period was 15.84%, 12.52%, 4.03% and 0.97%, respectively. Among them, the highest frequency of droughts occurred in Ningxia, Inner Mongolia and central Shaanxi provinces. Drought causation in the Yellow River basin is more influenced by human activities than climate change in the middle and lower reaches, while climate change is the main factor in the upper reaches. Overall, YCDI is a reliable indicator for monitoring the spatial and temporal evolution of drought in the Yellow River basin, and it can be used for monitoring soil moisture changes and vegetation dynamics, which can provide scientific guidance for regional drought governance.

The adverse effects of climate change can be mitigated through apt interventions like Climate Smart Agriculture (CSA). The adoption of CSA technologies by the farmers is muddled because of the constraints faced by them in different contexts. The motive of the study was to identify the key constraints that inhibit the adoption of CSA technologies by farmers. Suggestions proposed by the farmers for increasing the adoption rates of the CSA technologies were also highlighted in the study. Four blocks with less average rainfall from the climate vulnerable district of Andhra Pradesh were chosen for the study. Two villages from each block were selected based on the highest number of farmers. Multi-stage proportionate random sampling was adopted for the study. Data was collected through open ended questions by personal interview methos. The responses were categorised and subjected to frequency and percentage analysis. The results demonstrated that lack of storage facilities was the major constraint faced by majority (85.71%) of the farmers followed by the uncertain returns and results of the CSA technologies (79.50%) as perceived by the farmers. Government and policy interventions, use of extension approaches in right time might help in overcoming the constraints. Providing trainings on CSA (83.23%) was the most suggested measure as it helps the farmers to increase their knowledge and clear their doubts on the outcomes of CSA. Demonstration of CSA technologies to the farmer improves their knowledge and skill.

We aim to evaluate the basic characteristics of SRS MapCHECK (SRSMC) for CyberKnife (CK) and establish a dose verification system using SRSMC for the tumor‐tracking irradiation for CK. The field size and angular dependence of SRSMC were evaluated for basic characterization. The output factors (OPFs) and absolute doses measured by SRSMC were compared with those measured using microDiamond and microchamber detectors and those calculated by the treatment planning system (TPS). The angular dependence was evaluated by comparing the SRSMC with a microchamber. The tumor‐tracking dose verification system consists of SRSMC and a moving platform. The doses measured using SRSMC were compared with the doses measured using a microchamber and radiochromic film. The OPFs and absolute doses of SRSMC were within ±3.0% error for almost all field sizes, and the angular dependence was within ±2.0% for all incidence angles. The absolute dose errors between SRSMC and TPS tended to increase when the field size was smaller than 10 mm. The absolute doses of the tumor‐tracking irradiation measured using SRSMC and those measured using a microchamber agreed within 1.0%, and the gamma pass rates of SRSMC in comparison with those of the radiochromic film were greater than 95%. The basic characteristics of SRSMC for CK presented acceptable results for clinical use. The results of the tumor‐tracking dose verification system realized using SRSMC were equivalent to those of conventional methods, and this system is expected to contribute toward improving the efficiency of quality control in many facilities.

A novel reactive inkjet printing (RIJ) process for fabricating environmentally benign, conductive zinc structures on biodegradable substrates is reported. A precursor consisting of oxidized zinc microparticles is formulated into a viscous ink for high‐resolution, high‐repeatability screen printing. A single RIJ process is performed to selectively dispense an acid‐based oxide etching agent onto the screen‐printed zinc ink to significantly improve its electrical conductivity, up to 4 × 104 S m−1. The RIJ process enables precise control of the amount of deposited etching agent, allowing control of conductivity and avoiding damage caused by excessive acid exposure. The RIJ process deposits the etching agent selectively on the screen‐printed, water‐soluble zinc patterns, thus preserving the print fidelity by avoiding ink smearing that can occur when using a blanket treatment such as submersion. A printed biodegradable antenna with a minimum feature size of 500 μm for use with a batteryless radio frequency identification (RFID) chip is fabricated as demonstration. Due to the higher ink conductivity and improved pattern fidelity, the antenna fabricated by the RIJ process shows a ≈2.2× increase in reading distance compared with a similar antenna that is screen printed and activated using a drop‐casting process.
