Objective To assess knowledge and practices related to snakebite prevention among Chinese residents. Methods By using a multistage random sampling approach augmented by snowball sampling, we surveyed residents from 10 provinces, one municipality and one autonomous region south of the Yangtze River Basin between May 2022 and February 2023. We supplemented the data with a national online survey. We used a [chi square]-test to identify differences in knowledge and behaviour across various demographic characteristics. We conducted multifactor logistic regression analyses to evaluate factors potentially influencing snakebite knowledge and practices. Findings We obtained 55 775 valid survey responses, 16 200 respondents from the face-to-face survey and 39 575 respondents from the online survey. Only 25.7% (14 325) respondents demonstrated adequate knowledge about snakebites whereas 25.6% (14 295) respondents knew basic first-aid practices or preventive behaviours. Age, marital status, educational attainment, occupation, type of residence and frequency of exposure to nature are significant independent variables affecting snakebite knowledge (P-values: Conclusion There is a notable shortfall in knowledge, first aid and preventive behaviours among Chinese residents regarding snakebites. Misguided first aid practices can severely compromise the effectiveness of evidence-based therapeutic interventions. Consequently, improving health education concerning snakes and snakebites in this population is needed.

[phrase omitted] Objectif Evaluer les connaissances et pratiques liees a la prevention des morsures de serpent chez les personnes residant en Chine. Methodes A l'aide d'une approche d'echantillonnage aleatoire a plusieurs degres agrementee d'un echantillonnage en boule de neige, nous avons interroge les habitants de dix provinces, d'une municipalite et d'une region autonome au sud du bassin du fleuve Yangtse entre mai 2022 et fevrier 2023. Nous avons complete ces donnees par une enquete nationale en ligne. Nous avons utilise le test du [chi square] pour reperer les differences entre les connaissances et comportements en lien avec plusieurs caracteristiques demographiques. Enfin, nous avons effectue des analyses multifactorielles de regression logistique afin de determiner les facteurs susceptibles d'influencer les connaissances et pratiques relatives aux morsures de serpent. Resultats Nous avons enregistre 55 775 reponses valides dans le cadre de l'enquete: 16 200 lors d'entretiens en face-a-face et 39 575 en ligne. Seulement 25,7% (14 325) des participants etaient suffisamment informes sur les morsures de serpent, tandis que 25,6% (14 295) des participants connaissaient les premiers soins de base ou les comportements preventifs. Lage, l'etat civil, le niveau d'education, la profession, le type d'habitation et la frequence d'exposition a la nature etaient autant de variables independantes ayant un impact non negligeable sur les connaissances en matiere de morsures de serpent (valeurs-p: < 0,05). En outre, le genre, l'age, l'etat civil, le niveau d'education, la profession et le type d'habitation etaient autant de variables independantes ayant un impact non negligeable sur le comportement en matiere de prevention des morsures de serpent et de premiers soins (valeurs-p: < 0,05). Conclusion Chez les personnes residant en Chine, les connaissances, les pratiques en matiere de premiers soins et les comportements preventifs relatifs aux morsures de serpent ne sont pas suffisants. Accomplir les mauvais gestes lors des premiers soins peut serieusement compromettre l'efficacite des interventions therapeutiques eprouvees. Il est donc imperatif de mieux former cette population aux serpents et a leurs morsures.

Metodos Mediante el uso de un enfoque de muestreo aleatorio de etapas multiples aumentado por el muestreo de bola de nieve, se encuesto a los residentes de 10 provincias, un municipio y una region autonoma al sur de la cuenca del rio Yangtze entre mayo de 2022 y febrero de 2023. Se complementaron los datos con una encuesta nacional en linea. Se aplico una prueba [chi square] para identificar las diferencias en los conocimientos y los comportamientos segun diversas caracteristicas demograficas.

Resultados Se obtuvieron 55 775 respuestas validas, 16 200 de la encuesta presencial y 39 575 de la encuesta en linea. Solo el 25,7% (14 325) de los encuestados demostro tener conocimientos adecuados sobre las mordeduras de serpiente, mientras que el 25,6% (14 295) conocia practicas basicas de primeros auxilios o conductas preventivas. La edad, el estado civil, el nivel de estudios, la ocupacion, el tipo de residencia y la frecuencia de exposicion a la naturaleza son variables independientes significativas que afectan a los conocimientos sobre las mordeduras de serpiente (valores de p: Conclusion Los residentes chinos presentan un notable deficit de conocimientos, primeros auxilios y conductas preventivas en relacion con las mordeduras de serpiente. Las practicas erroneas de primeros auxilios pueden comprometer gravemente la eficacia de las intervenciones terapeuticas basadas en la evidencia. En consecuencia, es necesario mejorar la educacion sanitaria relativa a las serpientes y a sus mordeduras en esta poblacion., Introduction Snakebite envenoming is an important public health problem in low- and middle-income tropical countries. Venomous snakebites can cause serious local and systemic symptoms, such as tissue damage, systemic muscular [...]

The Center Solenoid Model Coil (CSMC) is a pre-research project of CFETR, and its task is to design and manufacture the CS superconducting model coil to gain wider experience in solving the related technical problems existing in design and construction of CFETR CS coils. The expected achievement is to charge the CSMC up to the operation current of 47.65 kA and the maximum magnetic field to 12 T with a swift rump rate of 1.5 T/s without quench. Quench detection by voltage measurements is likely to be the fastest available technical solution to avoid coil's damage caused by quench, but the voltage detection is a real challenge due to large noise induced by the power supply in alternating current operation. The pick-up sensors, comprising the co-wound wire (CWW) and the co-wound tape (CWT), are used in the CSMC quench detection system for noise compensation and suppression. To accurately compensate all related induced voltage in the multi-pulse coil system, the foremost task is to estimate the static inductance matrix between the CSMC and its pick-up sensors. In this paper, a numerical model is developed for inductance calculation and analysis. Moreover, several numerical simulations with this design model to evaluate the maximum inductive noises and quench detection signals by CWW and CWT have been conducted for the case of the worst test scenarios.

Mastering nuclear fusion, which is an abundant, safe, and environmentally competitive energy, is a great challenge for humanity. Tokamak represents one of the most promising paths toward controlled fusion. Obtaining a high-performance, steady-state, and long-pulse plasma regime remains a critical issue. Recently, a big breakthrough in steady-state operation was made on the Experimental Advanced Superconducting Tokamak (EAST). A steady-state plasma with a world-record pulse length of 1056 s was obtained, where the density and the divertor peak heat flux were well controlled, with no core impurity accumulation, and a new high-confinement and self-organizing regime (Super I-mode = I-mode + e-ITB) was discovered and demonstrated. These achievements contribute to the integration of fusion plasma technology and physics, which is essential to operate next-step devices.
