The present work is focused on pyrolysis of polystyrene waste for production of combustible hydrocarbons. The experiments were performed in an indigenously made furnace in the presence of a laboratory synthesised copper oxide. The pyrolysis products were collected and characterised. The Fourier transform infrared spectra showed that the liquid fraction contains C-H, C-O, C-C, C=C and O-H bonds, which correspond to various aliphatic and aromatic compounds. Gas chromatography-mass spectrometry traced compounds ranging from C1 to C4 in the gaseous fraction, whereas in the liquid fraction 15 components ranging from C3 to C24 were detected. From the results it has been concluded that CuO as a catalyst not only increased the liquid yield but also reduced the degradation temperature to great extent. Fuel properties of the pyrolysis oil were determined and compared with standard values of commercial fuel oil. The comparison suggested potential application of pyrolysis oil for domestic and commercial use.The objectives of this paper were to (a) systematically review studies that explored the effects of exercise order (EO) on muscular strength and/or hypertrophy; (b) pool their results using a meta-analysis; and (c) provide recommendations for the prescription of EO in resistance training (RT) programmes. A literature search was performed in four databases. Studies were included if they explored the effects of EO on dynamic muscular strength and/or muscle hypertrophy. The meta-analysis was performed using a random-effects model with Hedges' g effect size (ES). The methodological quality of studies was appraised using the TESTEX checklist. Eleven good-to-excellent methodological quality studies were included in the review. When all strength tests, that is, both in multi-joint (MJ) and single-joint (SJ) exercises were considered, there was no difference between the EOs (ES = -0.11; p = 0.306). However, there was a difference between the MJ-to-SJ and SJ-to-MJ orders for strength gains in the MJ exercises, favouring starting the exercise session with MJ exercises (ES = 0.32; p = 0.034), and the strength gains in the SJ exercises, favouring starting the exercise session with SJ exercises (ES = -0.58; p = 0.032). No significant effect of EO was observed for hypertrophy combining site-specific and indirect measures (ES = 0.03; p = 0.862). In conclusion, increases in muscular strength are the largest in the exercises performed at the beginning of an exercise session. For muscle hypertrophy, our meta-analysis indicated that both MJ-to-SJ and SJ-to-MJ EOs may produce similar results.Objectives Occupational safety and health (OSH) interventions emphasizing regulation or education have had limited success in reducing agricultural accidents and fatalities. There is a growing interest in sociocultural approaches to OSH promotion amongst farmers, such as peer learning groups (PLGs). The level of OSH engagement within farmer PLGs (e.g. dairy discussion groups (DDGs)) is unknown. This study evaluates Irish DDG engagement with OSH in 2016 to better understand how DDGs contribute to OSH promotion.Methods A mixed-mode (online, postal, and telephone) retrospective survey of 121 DDG representatives (i.e. chairperson or long-term member) assessed voluntary OSH engagement in 2016, including the location, frequency, duration, and content of OSH discussions.Results Representatives of 96 DDGs participated in the survey and met the survey criteria. Most DDGs discussed OSH to some extent in 2016 (96%), including sharing personal experiences of accidents and illnesses (89%) and close calls (82%). For 76 DDGs, at least one meeting in 2016 addressed specific hazard and risk management topics. Groups were diverse with respect to discussion frequency, duration, and topics discussed.Conclusion Farmers actively engaged with OSH in most DDGs surveyed, suggesting dairy farmers value OSH discussions. The findings illustrate the role of DDGs in OSH promotion, as a space for farmer-led, peer-to-peer knowledge-sharing. Farm advisory (extension) services and OSH professionals can strengthen OSH engagement through tailored resources that reflect contemporary OSH knowledge and popular discussion approaches (e.g. experience-sharing).Purpose We aimed to compare the findings of a segmental speckle-tracking strain of right ventricle with those of cardiac magnetic resonance imaging in this setting.Methods In 26 patients with operated tetralogy of Fallot (mean age, 15.35 ± 2.3 years; range 11-18 years), right ventricular segmental speckle-straining (the basal, mid, apical segments of right ventricular septum and lateral free wall, and right ventricular apex) were determined using two-dimensional echocardiography. The echocardiographic findings were compared to right ventricular ejection fraction, right ventricular indexed end-diastolic volume, indexed end-systolic volume and pulmonary regurgitation fraction at cardiac magnetic resonance.Results Right ventricular global speckle strain was -18.6 ± 3.7and lateral free wall strain was -17.8 ± 4.9. Indexed right ventricular end diastolic volume was 171.7 ± 23.3 ml/m2, indexed right ventricular end systolic volume was 95.1 ± 35.0 ml/m2 and right ventricular ejection fraction was 44.76 ± 9.39%. Basal inferior septum is correlated with indexed right ventricular end-diastolic volume (RVEDV; r = -0.521, p = 0.015) and pulmonary regurgitation fraction (r = -0.584, p = 0.015). Cardiac magnetic resonance (CMR)-derived RVEDV is correlated with lateral free wall (r = -0.465, p = 0.034) and Global RV (r = 0.442, p = 0.045).Conclusion Right ventricular basal inferior septal and apical longitudinal strain correlates with the measures of right ventricular performance on CMR. These parameters would be useful to monitor right ventricular performance in patients after tetralogy of Fallot repair.OBJETIVO identificar barreras y facilitadores sobre dieta saludable y actividad física en mujeres embarazadas con sobrepeso y obesidad que viven en entornos de vulnerabilidad social y económica, destacando determinantes socioeconómicos y culturales. selleck chemicals llc METODOLOGÍA estudio cualitativo longitudinal, donde las entrevistadas corresponden a mujeres embarazadas seleccionadas de una cohorte prospectiva en México. Se aplicó una guía semiestructurada de entrevista que exploró barreras y facilitadores para llevar una dieta saludable y poder realizar actividad física. Las entrevistas se transcribieron y codificaron en Atlas Ti, generando 23 códigos temáticos. RESULTADOS existen barreras y facilitadores contextuales y sociales que predisponen un mayor riesgo de padecer sobrepeso y obesidad durante el embarazo. Destacan conocimientos limitados sobre una dieta saludable, condiciones de vulnerabilidad social, así como un sentido de fragilidad en las mujeres que incrementa su sedentarismo. CONCLUSIONES en el diseño e implementación de intervenciones en promoción de la salud es fundamental considerar las barreras y facilitadores culturales y socioeconómicas sobre alimentación saludable y actividad física durante el embarazo, para desarrollar intervenciones de salud pública que favorezcan una mayor prevención de sobrepeso y obesidad en mujeres embarazadas.
