Authors:   University of Wollongong, Australia, Wilson Val , Brown Donna ,   Ulster University, Northern Ireland, McCance Tanya ,   Ulster University, Northern Ireland
Published: May 2021

Background and aim: This study reports the outcomes from an international study that implemented a set of person-centred nursing key performance indicators across a range of services provided to sick children. It aims to explore the factors that influenced the successful implementation of those indicators, and assess the impact of the evidence generated on person-centred practice across the children’s services. Methods: Twelve organisations across Australia and Europe participated, with data collected in 2015 and 2016 and analysed using thematic analysis. Semi-structured interviews and focus groups were conducted with staff, including executive sponsors, managers, facilitators and clinical nursing teams. The COREQ guidelines were considered in the conduct and reporting of this study. Results: The results describe the impact of implementing the key performance indicators from the perspective of nurses operating at different levels within organisations. The following six themes became apparent: credibility of the key performance indicators; uncovering the whole picture; embracing nursing; engaging in the process; connecting with others; and achieving healthful outcomes. Conclusion: The findings from this study confirm an emerging relationship between the nature of evidence generated by the person-centred nursing key performance indicators and its use in practice. Also highlighted was the importance of facilitation in the process of data collection and in understanding the data and the context in which it is used. Implications for practice: This study will be of interest to clinical nurses, educators, managers and facilitators of cultural change. The data generated through the implementation of the person-centred nursing key performance indicators evidences the global contribution of nursing across services provided to children and their families Engaging staff at all levels in an organisation enhances implementation of evidence that is meaningful for nursing practice The triangulated evidence generated by the key performance indicators and accompanying measurement tools offers feedback that can drive improvements in nursing practice

Background: Storytelling is an important tool for enacting relational approaches to practice development in care homes. Using storytelling methods can enhance the capacity of care home communities to respond to the emerging needs of people living with dementia. Aim: To explore the potential of the LIFE session storytelling method as a route to innovation in practice. Method: The method described in this article is the Learning and Innovating from Everyday Excellence (LIFE) session method, developed as a culture change initiative by facilitators from the My Home Life care home initiative in Scotland. LIFE sessions aim to take stories from everyday practice and use a structured format of four questions to help people talk collaboratively about ideals and practical ideas that can be taken forward to benefit those who live, work in or visit the care setting. Results: A total of 14 LIFE sessions took place as part of Kinections, a broader study exploring community in care homes. The following reflections were derived using illustrative examples from three of these storytelling sessions, used in this study: the sessions helped move stories from the specific (one resident) to the universal (practice development and culture change that can benefit everyone in the home); the sessions involved a process that could in itself support development of connections among those involved; and they inspired and encouraged people to feel confident to bring their learning and ideas into practice in a timely way. Conclusion: This article illustrates how the LIFE session method can be used to structure a discussion that uses a short everyday story as a route into a generative conversation that can inspire innovation in practice. Implications for practice: LIFE sessions provide a format for illustrating the significance and potential for learning and development of everyday experiences in care homes. They can be facilitated reasonably quickly, with a wide range of people and across a wide range of topics LIFE sessions can facilitate generative experiences and encourage generative outcomes through those involved feeling inspired and enabled to take forward small, meaningful ideas and actions
Evaluating the co-production of active ward principles in an inpatient setting: staff developments from using person-centred practice developmen
Authors:   NHS Greater Glasgow and Clyde, Glasgow, Scotland, Harvey Juliet , Cameron Heather ,   NHS Lothian, Edinburgh, Scotland
Published: May 2021

Background: In the acute hospital environment deconditioning is a major risk factor, with around 90% of the day spent sitting or lying down. A physiotherapy and occupational therapy Active Wards Special Interest Group was formed to provide peer support and act as a platform for sharing resources and ideas to increase opportunities for physical activity in the inpatient setting. Drawing on the nine principles of Practice Development, a person-centred, participatory approach was adopted. These values promote time and space for the team to grow and develop together, accounting for best evidence, personal and professional experience. The group co-produced a toolbox of resources, active wards principles and formed a group of experts to help others. Aim: To evaluate the experience of staff engaging in this work with the objective of learning from the experience and make recommendations for replication and continuation of the improvement process. Methods: Members of the special interest group and their team leads were invited to complete an online self-reporting questionnaire defining their experiences of participating in the group. Results: Engaging clinicians in improvement through person-centred practice development processes delivers benefits for patients, services and clinicians. Key findings for staff development were identified as significantly improved (response rate of 78%) through i) active learning principles used for meetings, ii) effective and diverse communication strategies, and iii) group cohesion by engaging in a practice-based initiative. Group members and team leads observed personal, professional and service development. Participants made new connections, had a sense of a common vision and felt part of a collaborative process where ideas and feedback were shared. Where changes in patient activity levels had been observed, at least two-thirds of teams attributed this to having a team member in the group. Conclusions and implications for practice: Clinicians require adequate time, space and support to achieve improvements When engaged with active learning and participatory approaches, clinicians make better use of meetings to develop and form principles of practice relevant to their clinical context and patient groups Engaging in person-centred practice development processes enables clinicians to develop transferable skills Practice development methods can be readily replicated for initiating and engaging clinicians in other practice-driven development projects

Background: The absence of patient-reported outcome measures (PROMs) for a specific construct or target population suggests a need for such measures to be developed. A case in point is the domain of falls efficacy; a PROM for balance recovery confidence was proposed to improve older persons ’agency to arrest a fall. Appropriate participation in its development by relevant stakeholders was identified as essential to maximise the utility of the PROM and its potential to enhance patient care. There is a gap in the practice development literature in terms of PROMs for older persons. This article aims to encourage researchers to use the principles of practice development to address this gap by involving relevant stakeholders to gain greater insight. Methods: The nominal group technique and the Delphi technique were used to generate and refine the content of the measure, and content analysis was applied to assess and summarise the data. Findings: Unique themes emerged, such as ‘agency of older people in the prevention of falls ’from the community-dwelling older adults in Singapore, and ‘clinical specificity ’from an international panel of healthcare professionals. Common themes including ‘relevance to the target population’, ‘comprehensibility ’and ‘cultural and contextual sensitivity ’were found in both groups. Conclusion: A collaborative, inclusive and participatory approach involving different stakeholders, underpinned by practice development methodology, can offer rich insights for PROM developers. Implications for practice: Meaningful perspectives are generated from a diversity of views shared by representatives from all stakeholder groups involved in caregiving Participation of different stakeholders, such as physiotherapists, occupational therapists, nurses, doctors, podiatrists and older persons, provides a more robust and authentic approach to developing a PROM for older persons
The influence of music on black, Asian and minority ethnic women working in the field of domestic violence and abuse: critical reflection on music as method
Authors:   University of Westminster, London, England, Waddington Kathryn , Erbmann Maria ,   Lambeth Council, London, England
Published: May 2021

Background: Arts-based research practices draw upon music, visual art, poetry and other media as methodological tools throughout the research process. There is also growing recognition of the contribution of arts-based practices, including music as method, to interdisciplinary fields of health, social sciences, humanities and education. Research into: i) the role of music as a therapeutic intervention; and ii) the use of creative approaches to practice development are clearly evident in the literature. What is less evident is the role of music as method. This article is a critical reflection on the novel use of music recordings during qualitative interviews in a small-scale study exploring the role of music in the work and lives of black, Asian and minority ethnic women working in a UK domestic violence and abuse charity. Aim: To describe a critical reflection on music as method in a small-scale qualitative research study. Implications for practice: Music has potential as a model and method in qualitative health and social care research practice, particularly with sensitive topics such as drug misuse or homelessness Music is a means of developing compassion and critically reflective practice development in the field of domestic violence and abuse and other areas of practice
Co-researchers in motion: a journey of evolving relationships. A critical reflection on the co-operation between two older adults and a nurse researcher

Published: May 2021

Background: There is a growing amount of research in which older adults contribute as co-researchers. The quality of this research depends, among other factors, on the nature of relationships between professional researchers and co-researchers. Reflections on these relationships can offer structured insight into this form of research. Aim: Our reflection on the co-operation between two older adults and a nurse researcher aims to share the lessons learned based on a critical understanding of our journey. Our main questions are: 1. How has the relationship developed over time, including in terms of mutuality and equality? 2. Which moments have been decisive in this development? Conclusion: We regard our co-operative relationship as a ‘dynamic search’. The meaning of mutuality and equality may change over time and so enrich the relationships. There is a need for further understanding into how these values can be nurtured in different configurations of researchers and co-researchers. Implications for practice: Evolving relations can be nurtured through deliberative sharing of the perceptions, expectations and experiences of the researchers and co-researchers Combining a formal working atmosphere with informal moments helps the research team respond to the individual needs of its members To enhance equality and mutuality, it is important to appreciate and value everyone’s contribution rather than concentrating on ‘what ’or ‘how ’individuals contribute
Implementing a vision of person-centredness across a new university hospital in Denmark

The experience of a collaborative process to build a research and development culture at a new university hospital underlined that the Person-centred Practice Framework (McCance and McCormack, 2017) forms a solid and valuable foundation for ongoing work. The fact that the process has involved researchers, leaders at different levels, clinical nurse specialists and other healthcare professionals makes the framework’s focus on the whole care environment especially relevant. How work towards a nursing research culture developed into a person-centred strategy In 2010, the management at our hospital in Denmark established a director of nursing research position, with a remit to create, develop and support a research culture within the nursing and allied health professions. No guidance was offered on how this should be done and as a consequence the ideas and professional profile of the person hired were highly influential (Hølge-Hazelton, 2019). Having a solid background in action research and studies of vocational and professional education, the new director launched a collaborative process to identify the desired characteristics of the research culture. Those contributing included the networks of clinical development nurses and head nurses, and the executive director of nursing. The proposed vision that emerged was: Our research culture should be constructive, creative, inclusive and visible at all levels of the hospital. This vision was discussed and agreed among all head nurses at the hospital. The idea was that the culture should be everybody’s business and include all levels of nursing, and furthermore that these levels would be interdependent and dynamic. The strategy to achieve this was defined as ‘bottom up, top down and don’t forget the middle’, to signal that research and development are closely related and that they should be participatory, based on a broad understanding of evidence (Rycroft-Malone, 2010), clinically relevant, and supported by the hospital’s leadership. Within the first years of work towards realising the vision, two more nursing researchers were hired in clinical departments at the hospital. They also had a background in personal and organisational learning processes, organisational development and action research. Their task was to support the realisation of the strategy at departmental and unit level.
La dramaturgia bíblico-televisiva en TV Record
Authors: Scola Jorge
Published: May 2021

Este artículo propone una discusión en la intersección de las áreas de antropología de la religión y el laicismo, eligiendo como objeto de estudio el ciclo de producciones relacionadas con el Antiguo Testamento iniciado en 2010 y transmitido por Rede Record de Televisão, propiedad de la Iglesia Universal del Reino de Dios. Desde sus comienzos, estos son productos de la industria cultural que se han entrelazado en tensiones y discusiones sobre la lógica que subyace a la demarcación de los límites entre el dominio de lo religioso y el entretenimiento (Meyer; Moors, 2006). En esta convergencia identificada entre las narraciones bíblicas y su consumo actual y mediada por la producción de la industria cultural, se destacan las áreas de circulación y producción de estos mensajes. También destaco la especificidad de esta producción de temas del Antiguo Testamento en comparación con las publicaciones anteriores de lo que identifico como el "primer ciclo de drama televisivo religioso", transmitido a fines de la década de 1990. La investigación destaca el movimiento que algunos agentes identifican como un "giro judío" de la Iglesia Universal en convergencia con la producción de miniseries y novelas ancladas en el texto del Antiguo Testamento.
El papel del misionerismo en la configuración del imaginario social de los Adventistas del Séptimo Día
Authors: Galdino Marcos
Published: May 2021

El presente trabajo discute los principales componentes del imaginario social de los Adventistas del Séptimo Día, con un enfoque en reflexiones sociohistóricas sobre la construcción del adventista centrada en sus características misioneras. Dialoga con las premisas de identidad, basada en valores bíblicos-cristianos, difundida simultáneamente a través de la expansión del adventismo y su fijación en pautas misioneras que involucraron, entre otros fundamentos, la expansión de su modelo educativo. Como resultado, se observó que la construcción del imaginario social no ocurre espontáneamente, sino a través de la asimilación de una gama infinita de símbolos que están anclados en los significados más diferentes; y en el caso de los Adventistas del Séptimo Día, por una clara intención de aquellos que asumen la responsabilidad de convertirse en propagadores de los valores que constituyen su fundamento doctrinal, ya que cuando se convierte en adventista, necesariamente se convierte en misionero.

Reflexiones de Hannah Arendt sobre los salones berlineses dirigidos por mujeres judías
Authors: Calderón Melnick Paula
Published: May 2021

En este trabajo analizaremos, siguiendo los planteamientos realizados por Hannah Arendt, cómo se produjo la asimilación de las mujeres judías en Berlín, en el contexto de la emancipación del pueblo judío a la Alemania de finales del siglo XVIII y principios del XIX. Para ello explicaremos, recorriendo el estudio realizado por la filósofa alemana, cómo se desarrollaron los salones berlineses dirigidos por mujeres judías, en los que se reunía la sociedad más diversa de la época. En este sentido, nos enfocaremos, continuando con la autora, en cómo se originó el salón de Rahel Varnhagen y en cómo las consecuencias de la emancipación judía produjeron el cierre definitivo de este espacio. Con este fin, nos basaremos en las obras tempranas de Arendt escritas en la década de 1930, La asimilación original. Un epílogo con motivo del primer centenario de la muerte de Rahel Varnhagen; Salón Berlinés; Rahel Varnhagen. Vida de una mujer judía, además de su primera gran obra, publicada dos décadas más tarde, Los orígenes del totalitarismo.

En la introducción de este voluminoso texto los autores definen el objetivo de este libro: "Reunir en una misma publicación aquellos trabajos que simbolizan, en sus diferencias y congruencias, la consolidación de una temática que se gestó en paralelo a la construcción de un campo de investigación multidisciplinar" (2018: 16). No es casual que en tiempo de dictadura, sobre todo en Chile, en los años 80, se gestara un grupo de sociólogos de la religión interesado, sobre todo, en ver como los discursos religiosos, servían para operar como fuente de legitimación de la dictadura de Pinochet. El encanto que producían los evangélicos con su Te Deum, obligó a desempolvar el clásico libro de Lalive del año 1968. En Argentina el derrotero fue un tanto distinto, pero hay cruces de interés.
La mujer como agente religioso en la política

Published: May 2021

En una perspectiva interdisciplinaria, se investigó el escenario de superposición entre la religión y la política, en particular la participación femenina y evangélica en las elecciones para concejal en 2016, especialmente en lo que respecta a la activación de signos religiosos para construir el carisma ante el electorado y teniendo como el lugar de investiga el municipio de Campo Mourão-PR. Como extracto empírico se tiene la Pastora Jurema Portes, de la Iglesia del Evangelio Cuadrangular, que se presentó como una opción al electorado evangélico, actuando como agente religioso y utilizando un proyecto institucionalizado de la Iglesia para reforzar su capital político. El corpus documental consiste en entrevistas semiestructuradas y materiales de campaña puestos a disposición por la candidata en su perfil de red social. La investigación señala que el pertenecimiento a grupos minoritarios, el uso de la presencia institucionalizada de su denominación religiosa y la activación de signos religiosos en sus materiales y discursos no son suficientes para el éxito electoral, sino para el éxito político, en el que se destaca la importancia de la figura femenina y evangélica.
A Case of Potential Inborn Error of Metabolism as a Cause of Young Onset Psychosis
Authors: Amiruddin Mohd Kassim Mohd , Tze Ping Pang Nicholas , Haniff Abdullah Muhammad , Bahar Norharlina
Published: May 2021

Introduction: Young onset psychosis has poor prognosis, and inborn errors of metabolism (IEM) can be easily missed. There is scarce information regarding IEM and young onset psychosis in Malaysia. Case Report: A 15-year-old Malay girl presented at the age of 8 years with a history of intellectual disability and neuro-regression, subsequently developing psychotic and obsessive-compulsive symptoms several years later. Organic workup revealed elevated lactate levels. Urine organic acid chromatogram revealed a moderate peak of lactate however most other investigations were normal. As MRI brain is normal and there are no neurological signs it appears less likely there is an underlying IEM-related aetiology for psychosis. Discussion: Various IEMs can be related to psychosis however the incidence is very low and quality of evidence is poor. Thus, any psychiatric presentation, particularly with suggestive clinical signs, should warrant an organic (including IEM) workup since these causes are potentially reversible with supplementation.

Published: May 2021

The effect of aqueous extracts of the biomass of the adult Ulomoides dermestoides beetle on the delayed effects of the defoliant paraquat causing parkinsonism in experimental mice was evaluated. The motor activity of the animals was analyzed in behavioral tests using a rotarod and a vertical pole. The number of tyrosine hydroxylase-immunopositive neurons in the ventral part of the substantia nigra of the midbrains of experimental and control mice was studied by immunohistochemistry. In the model in vitro system with SH-SY5Y human neuroblastoma, the effect of the extracts on cell proliferation was examined in the absence and presence of the neurotoxin MPP+. The isolation of biologically active substances from raw biomass using cavitation effects made it possible to obtain extracts with protective properties in the model of an early stage of Parkinson's disease used in this study.
Meta-Analysis of Microdissected Breast Tumors Reveals Genes Regulated in the Stroma but Hidden in Bulk Analysis
Authors: Savino Aurora , de Marzo Niccolò , Provero Paolo , Poli Valeria
Published: May 2021

Background: transcriptome data provide a valuable resource for the study of cancer molecular mechanisms, but technical biases, samples’ heterogeneity and small sample sizes result in poorly reproducible lists of regulated genes. Additionally, the presence of multiple cellular components contributing to cancer development complicate the interpretation of bulk transcriptomic profiles. Methods: we collected 48 microarray datasets of laser capture microdissected breast tumors, and performed a meta-analysis to identify robust lists of genes differentially expressed in these tumors. We created a database with carefully harmonized metadata to be used as a resource for the research community. Results: combining the results of multiple datasets improved the statistical power, and the analysis of stroma and epithelium separately allows identifying genes with different contribution in each compartment. Conclusions: our database can profitably help biomarkers’ discovery and is readily accessible through a user-friendly web interface (https://aurorasavino.shinyapps.io/metalcm/).

Published: May 2021

Ovarian cancer (OC) represents the most common and lethal gynecologic malignancy, due to its increased incidence and mortality rate. It is usually diagnosed in advanced stages and, even though surgery and platinum-based treatment are initially efficient, recurrences emerge in over 70% of cases. Although there are multiple options of chemotherapy drugs from which to choose, little is known regarding the best strategy for prolonged survival. Thus, the aim of this study was to assess the effect that most frequently used chemotherapeutic regimens have upon time-to-treatment-failure (TTF) from the first line and beyond, considering clinical and biological factors which influence the treatment outcome of platinum-resistant recurrent OC. We retrospectively analyzed data from 78 patients diagnosed with platinum-resistant OC, who underwent chemotherapy-based treatment with or without anti-angiogenic therapy at OncoHelp Oncology Center, Romania (January 2016 - February 2021). Our study identified positive predictive factors for TTF related to anthropometry (age over 60 for patients treated with topotecan with or without bevacizumab), renal function (creatinine levels between 0.65 and 1 mg/dl for patients treated with regimens containing bevacizumab and pegylated liposomal doxorubicin) and treatment choice (bevacizumab in combination with pegylated liposomal doxorubicin or topotecan used from the first line and beyond).
Exploring patterns in modularity of protein interaction networks across the tree of life using Spectral Entropy
Authors: Swain Anshuman , Milzman Jesse , Fagan William F
Published: May 2021

Modularity and organizational hierarchy are important concepts in understanding the structure and evolution of interactions in complex biological systems. In this work, we introduce and use a spectral characterization measure (Spectral Entropy) to quantify modularity in protein-to-protein interaction (PPI) networks in species across the tree of life. We evaluated the relation between the size of a PPI network and its (Spectral Entropy-based) modularity, and found a sigmoidal response between the two. We also found significant differences in the distribution of Spectral Entropy values among the three domains of life (Bacteria, Archaea, Eukaryotes). To explore further correlations with biological traits, we focused solely on bacterial PPI networks, which are the most numerous among the three domains and had associated trait metadata, and investigated how modularity impacts or is impacted by growth, aerobicity, selection and location on the tree of life. We found no relation between maximal growth rate and Spectral Entropy, but a strong dependence between G-C content (a proxy for selection) and Spectral Entropy. We also discovered that Spectral Entropy is negatively affected by phylogenetic placement (evolutionary distance from the last universal common ancestor). The general nature of the Spectral Entropy measure of hierarchical modularity in networks suggests that it will be useful in other settings where structural properties of real-world networks are being compared.

In the traditional measurement theory, precision is defined as the dispersion of measured value, and is used as the basis of weights calculation in the adjustment of measurement data with different qualities, which leads to the trouble that trueness is completely ignored in the weight allocation. In this paper, following the pure concepts of probability theory, the measured value (observed value) is regarded as a constant, the error as a random variable, and the variance is the dispersion of all possible values of an unknown error. Thus, a rigorous formula for weights calculation and variance propagation is derived, which solves the theoretical problem of determining the weight values in the adjustment of multi-channel observation data with different qualities. The results show that the optimal weights are not only determined by the covariance array of observation errors, but also related to the model of adjustment.

This paper examines how a driver’s perception of various speed levels, as well as driver’s speed perception from different positions, affect the propensity for motor vehicle crashes (MVCs). Data collection is performed in twelve experiments. 178 young drivers assessed the speed level from four positions; three of them relate to the speed perception of other vehicles on the road, while the remaining one represents the assessment of own speed. At each position, three speed levels were assessed: 30, 50, and 70 km/h. To process data, seven Type-2 fuzzy inference systems (T2FISs) are designed and tested in a sense of compliance with the empirical data. As a result, a relationship between the various forms of speed perception and participation in MVCs can be quantified. To examine the initial conclusions, the optimization of each of these T2FISs is performed by implementing the bee colony optimization (BCO) metaheuristic. The BCO based algorithm proposed in this paper achieved an average improvement of 21.17% in the performance of the initial T2FIS structures. The final results indicate that the drivers whose speed perception of the vehicle they are looking at from the rear side, as well as of the own vehicle, is poor have an elevated risk toward participation in MVCs compared to other forms of speed perception. The best-found T2FIS structures can be used as a decision-making tool that quantifies the driver propensity for MVCs, which can be useful in various educational and recruitment procedures in the field of transportation and traffic safety.

Whitefly (Bemisia tabaci Gennadius) is a hmpteran phyto polyphagous sucking insect pest which is an important pest of cotton that causes economic losses to the crop by reducing its yield and quality. Ecdysteroids like 20-hydroxy ecdysone (20-E), have significant role in larval moulting, development, and reproduction in pterygota insects. Intending to obstruct these fundamental, developmental physiological processes, the receptor of 20-E, the Ecdysone Receptor (BtEcR) of Bemisia tabaci has been targeted. To identify potent inhibitors of BtEcr, 98,072 natural compounds were retrieved from ZINC database. A structure-based virtual screening of these compounds was conducted for their binding to BtEcR and the top two compounds (ZINC08952607 and ZINC04264850) were selected based on minimum binding energy. 50 ns molecular dynamics simulation (MDS) study was then performed for the prediction of dynamics and stability of BtEcR and top-scoring ligand-BtEcR complexes. Besides, g_mmpbsa tool was used to calculate and analyse binding free energy of BtEcR-ligand complexes. The results revealed that ZINC08952607 and ZINC04264850 had binding free energy of − 170.156 kJ/mol and − 200.349 kJ/mol, respectively. Thus, these ligands can be utilized as lead compounds for the development of environmentally safe insecticides against the whitefly.

Joining of aluminum to copper using Friction Stir Welding (FSW) is a primary manufacturing process that is in most applications followed by a secondary forming process. The objective of this research is to determine the optimum rotational and traverse speeds of Al-Cu Welded by FSW based on the formability of the joint. The formability and strength of Al-Cu joined by FSW are investigated under different operating conditions. Aluminum and copper blanks are welded at three different rotational speeds that are 910, 1280 and 1700 rpm, under three different traverse speeds, which are 16, 29 and 44 mm/min. The base metal used in this study is Aluminum (Al-1050) and copper under two conditions, i.e. as received and annealed. The mechanical properties of base metals and produced joints are evaluated by tensile and hardness tests. The Al-Cu joints by FSW are drawn into flangeless U and cup shapes in order to examine the formability of the joint. The maximum tensile load, punch load and forming index were obtained when Al is welded to annealed Cu at 1700 rpm and 16 mm/min, i.e. highest rotational and lowest traverse speeds, and that is due to the strain hardening of the joint. However, the ductility was maximum at 1280 rpm and 44 mm/min, i.e. moderate rotational and highest traverse speed. It can be concluded that if the Al-Cu joint by FSW will be used further in a forming process, it should be welded at a moderate rotational and high traverse speed in order to avoid strain hardening and improve the ductility of the joint.

Mining-induced surface cracks in gullies in shallow seams seriously threaten the development of ecological stability and the safety of mine production. The development law of surface cracks in shallow coal seam mining through double gullies terrain was studied, by taking the Cao Jiatan coal mine in the Yushen Mining Area as a project example. The function T and its discriminant were first put forward to describe the relative position both the surface cracks and working face advanced in shallow coal seam mining through double gullies terrain. The relationship between valley parameters of double gullies terrain and the relative position of surface cracks development was discussed through numerical simulation experiment, similar material simulation experiment and theoretical analysis. The results showed that when the working face passed through the G1 gully, the development of surface cracks led the working face. There were four surface cracks with a maximum width of 23 cm, and the maximum vertical displacement was 11 cm; while passing through the G2 gully, the development of surface cracks lagged the working face. There were seven surface cracks with a maximum width of 79 cm, and the maximum vertical displacement was 45 cm. It can be concluded that the relative position of crack development is greatly affected by geological conditions, gully depth, slope angle, span and other factors of the gully, among of which the gully slope angle is the main influencing factor. T and |T| value has a certain correlation with the lagging distance, crack width, vertical displacement and the total number of cracks in a single gully.
