We study the global existence and uniqueness of a strong solution to the kinetic thermomechanical Cucker-Smale(for short,TCS) model coupled with Stokes equations in the whole space.The coupled system consists of the kinetic TCS equation for a particle ensemble and the Stokes equations for a fluid via a drag force.In this paper,we present a complete analysis of the existence of global-in-time strong solutions to the coupled model without any smallness restrictions on the initial data.

Applying Design Thinking in Ecotourism Curriculum Design: The Educational Design Ladder

The design thinking approach transforms student’s learning process to connect with real-world experience, making connections between knowledge and improving critical thinking and problem-solving capability. Previous research has focused on what design thinking is taught (content) and how it is taught (learning modes and assessment). However, there needs to be an integrative approach in the context of ecotourism education. Therefore, applying Wrigley and Straker’s Educational Design Ladder mode, this study develops an Ecotourism Design Thinking Curriculum framework to combine the ecotourism content, teaching/learning mode and assessment.

Existence and features of the myodural bridge in gentoo penguins:a morphological study

Recent studies have evidenced that the anatomical structure now known as the myodural bridge(MDB)connects the suboccipital musculature to the cervical spinal dura mater(SDM).In humans,the MDB passes through both the posterior atlanto-occipital and the posterior atlanto-axial interspaces.The existence of the MDB in various mammals,including flying birds(Rock pigeons and Gallus domesticus)has been previously validated.Gentoo penguins are the world's fastest diving birds.The present study was therefore carried out to investigate the existence and characteristics of the MDB in Gentoo penguin,a non-flying,marine bird that can dive.For this study,six Gentoo penguin specimens were dissected to observe the existence and composition of their MDB.

Kenotomy,the Domain of Creative Thinking

Creativity is designative for the mankind,distinguishing it among the other species.Everyone is born with the affinity to speculate the perceived reality—overlaying it by his own imagination,inventing a playful use for the encountered items and refreshing extant ideas by new approaches,creating new mental outcome.The perceived world is not enough for the human mind,which challenges the given reality,animated by the need for questing and creatively exploring beyond it.As a result,the history of humanity is a history of realized inventions and different visions.If the creativity is an organic part of the human nature,why are so few mature people creative?

Sustainable manufacturing,life cycle thinking and the circular economy

Achieving sustainable patterns of consumption and production is perhaps the biggest challenge facing our society today. The de-mand for more safe environmentally benign products is rising and many companies are looking for new ways to progressively improve the sus-tainability of their products. Moreover, there are numerous opportunities and countless innovations, technological as well as non-technologi-cal,that need to be exploited to improve the sustainability of products. Manufacturing industry is an important sector of any economy and hasthe potential to become a driving force for enabling sustainable patterns of production and consumption through introducing efficient productionpractices and developing products and services that help reduce environmental impacts. The benefits of adopting an integrated policy towardsproduct development based on life cycle thinking and eco-design to stimulate improvement of the environmental performance of each part ofproduct life cycle phases and achieve sustainable patterns of production and consumption are emphasized. The challenges in implementingsustainable manufacturing and the circular economy approaches are listed. A number of solutions are suggested to face up these challenges,for instance, increased awareness of enterprises particularly SME's of product life cycle issues and the opportunities that are available for costsavings and profit making from eco-innovation in product development for both the domestic and export markets and providing practical helpand advice directly to enterprises on integrated product development to promote enterprise led Eco-innovation. Aiming at contributing to sus-tainable manufacturing in China, Sino-UK Low Carbon Manufacturing Consortium, a multi-disciplinary research and educational partnershipbetween academia, industry and government agencies in the UK and China with interest in sustainable manufacturing issues, has been formedrecently.The vision, aims and benefits of membership of the consortium are also discussed.

THE EXISTENCE OF GLOBAL SOLUTIONS FOR THE FULL NAVIER-STOKES-KORTEWEG SYSTEM OF VAN DER WAALS GAS

The aim of this work is to prove the existence for the global solution of a nonisothermal or non-isentropic model of capillary compressible fluids derived by J.E.Dunn and J.Serrin(1985),in the case of van der Waals gas.Under the small initial perturbation,the proof of the global existence is based on an elementary energy method using the continuation argument of local solution.Moreover,the uniqueness of global solutions and large time behavior of the density are given.It is one of the main difficulties that the pressure p is not the increasing function of the densityρ.

目的:基于TLR4/MyD88/NF-κB信号通路蛋白表达的观察,探讨针灸对胃黏膜“治未病”的作用机制。方法:将大鼠分为四组:正常组、模型组、预灸组和针预组,预灸组悬灸、针预组针刺“中脘”“足三里”,每穴20 min,1次/d,连续治疗7 d。针灸预处理结束后,模型组、预灸组、针预组制备胃黏膜损伤模型。评估胃黏膜损伤指数(UI),ELISA法检测大鼠血清TNF-α和IL-1β水平,免疫组织化学法和Western blot检测胃黏膜组织TLR4、MyD88、NF-κB p65蛋白表达水平。结果:模型组大鼠UI指数评分高于正常组(P<0.05),观察胃黏膜组织出现明显损伤,有出血灶,提示模型制备成功。与模型组比较,预灸组和针预组大鼠血清TNF-α、IL-1β浓度和TLR4、MyD88、NF-κB p65蛋白表达水平显著降低(P<0.05)。结论:针灸预处理对胃黏膜损伤可以起到预防作用,其作用机制可能是通过对TLR4/MyD88/NF-κB p65信号通路蛋白表达水平的调控,对大鼠胃黏膜损伤的炎性反应起抑制作用,从而达到对胃黏膜组织的保护作用。

THE EXISTENCE AND LOCAL UNIQUENESS OF MULTI-PEAK SOLUTIONS TO A CLASS OF KIRCHHOFF TYPE EQUATIONS

Personality Traits, Thinking Styles, and Emotional Intelligence in Nursing, towards Healthcare Providers’ Characterization and Safer Patient Care

Background: This study explored nursing personality traits (Big Five Inventory BFI), emotional intelligence (EI), and thinking styles (Rational, RS, and Experiential, ES) together with demographic data to see how they could relate and the implication of this on nurses and patient safety. Design: A cross-sectional study. Methods: Nursing sample (n = 435). Participants completed a self-report online survey, which included demographic information, followed by questionnaires to measure personality traits, thinking styles, and emotional intelligence. Results: Spearman’s rank correlation was computed to assess the relationship between EI and Extraversion;there was a moderate positive correlation between the two variables, r = 0.487, p r = 0.731, p r = 0.723, p r = -0.666, p r = 0.467, p Conclusion: Different studies consolidated each other, and all converge and channel into the concept of characterization of healthcare providers for better support to them and safer patient care. EI correlated with all BFI components, and both positively impacted all desirable behaviors. Therefore, it would be valuable if organizations invested in increasing EI in their providers as it might highlight areas for improvement and equip providers with appropriate and advantageous coping strategies.
