Tetragona Lepeletier & Serville is a genus of stingless bees with 14 recognized species occurring from Mexico to Argentina. The genus is characterized by velvety genal area, mesotibial spur present, and propodeal triangle glabrous. Within the genus, the truncata species group (T. truncata Moure and T. atahualpa sp. nov.) is characterized by worker metabasitarsus with posterior angle rounded and the mandible with two short teeth of similar length. Tetragona truncata is reported with new records for Ecuador (Napo and Orellana), Peru (Huánuco, Loreto, and San Martín), and Brazil (Acre [Rio Branco] and Tocantins [Itacá, Lizarda and Palmas]). In addition, T. atahualpa sp. nov. is described as a new species from regions of altitudes above 1,800 m in Colombia (Boyacá), Ecuador (Napo, Zamora-Chinchipe), and Peru (Pasco). We illustrate and discuss the identification of these two species. Survival after cardiac arrest depends on prompt and effective cardiopulmonary resuscitation (CPR). Transesophageal echocardiography (TEE) can be applied to evaluate the effectiveness of chest compression-decompression maneuvers in the setting of cardiac arrest undergoing CPR. The efficacy of chest compression can be continuously assessed by TEE that can improve the effectiveness of CPR guiding the rescuer to optimize or correct chest compression and decompression by directly examining the movements of the cardiac walls and valve leaflets. The review describes how to perform TEE in the emergency setting of cardiopulmonary arrest, its advantages, and limitations, and ultimately propose an echo-guided approach to CPR.The review describes how to perform TEE in the emergency setting of cardiopulmonary arrest, its advantages, and limitations, and ultimately propose an echo-guided approach to CPR. The present study compared visual outcomes in eyes with bilateral implantation of two multifocal intraocular lenses (MFIOLs)-the Eyecryl™ ACTV diffractive multifocal IOL (group 1) and AcrySof IQ ReSTOR multifocal IOL (group 2). This was a prospective, two-group observational longitudinal study of 118 eyes from 59 patients conducted at Laxmi Eye Institute, Panvel, India. We evaluated the patients at 1, 3, and 6months. We assessed visual acuity, contrast sensitivity, higher-order aberrations, reading speed, defocus curve, stereopsis, quality of life (QOL), and adverse events in these participants. The median (interquartile range) best-corrected distance visual acuity was 0.18 (0, 0.18) in group 1 and 0.18 (0, 0.18) in group 2 at 1, 3, and 6months; the difference was not statistically significant (p = 0.48). The binocular defocus curve in both groups showed two peaks at 0.0 to -0.5 D and at -2.5 D. The mean (95% confidence interval) critical print size was significantly different between groups 1 and 2Eyecryl and AcrySof groups were comparable for best-corrected visual acuity, photopic contrast sensitivity, defocus curve, reading parameters, stereopsis, and quality of vision. However, the Eyecryl group had better mesopic contrast and a lower proportion of unwanted images. Psychosocial quality of life was significantly better in the Eyecryl group; however, satisfaction was similar between groups. The cost of one of the lenses is less than the other. Thus, individuals with limited resources may opt for the Eyecryl™ ACTV, with similar visual outcomes.Recent research has shown a huge impact of non-renewable energy (NRE) production on environmental health. In this context, this work analyzes the effects of GDP growth and long- and short-term consumption of renewable and non-renewable energy (RE and NRE, respectively) on carbon emission in BRICS and OECD economies. The quantile autoregressive distributed lag (QARDL) model was employed on the panel data from 1980 to 2016. Findings suggest a negative GDP-carbon emission correlation and a positive NRE-carbon emission correlation in the considered economies. Furthermore, carbon emission decreases with increase in gross capital formation, whereas trade openness does not have any significant effect on carbon emission. It has been determined that the application of the error correction method (ECM) has less effect on energy consumption as compared to the past levels and changes in energy consumption. In the long-term, a positive correlation of carbon emission and energy consumption is observed, whereas limited short-term effects of energy consumption on carbon emission are observed. Compound 9 Therefore, an RE-based energy production approach is recommended in the selected region for the future projects.The chiral pesticide famoxadone is mainly applied to control fungal diseases on fruiting vegetables. The fungicidal activity, ecotoxicological effects, and degradation behavior of famoxadone enantiomers are less well known. In this study, a systemic assessment of the stereoselectivity of famoxadone was performed in cucurbits and soil. Famoxadone enantiomers presented distinct inhibitory activities among different fungal species. The bioactivities of R-(-)-famoxadone were 2.7-178 times higher than S-(+)-famoxadone toward five phytopathogens. Based on the obtained LC50 values, famoxadone was super toxic to Eisenia foetida (E. foetida). Moreover, the acute toxicity of R-(-)-famoxadone presented 167 times greater to E. foetida than that of S-(+)-famoxadone, indicating that R-(-)-famoxadone showed higher bioactivity toward target organisms and non-target organisms than S-(+)-famoxadone. In addition, a simple high-performance liquid chromatography (HPLC) method was established to determine the stereoselective degradation of famoxadone in two species of cucurbits (cucumber and chieh-qua) and in field soil. The half-life values of famoxadone degradation were from 5.4 to 14.1 days, indicating that famoxadone was easily degraded. Additionally, no stereoselective degradation was found in cucurbits and soil. The results may provide promising implications for comprehensive environmental and ecological risk assessments of famoxadone.Air quality in China is increasingly improving, but the situation facing the atmosphere environment is still dire. Regional atmospheric environmental problems characterized by PM2.5 pollutants are becoming increasingly prominent, especially in the Jing-Jin-Ji (3J) region. This study employs the generalized Divisia index approach to decompose the factors that influence the changes of PM2.5 emission in the 3J region. It is divided into 8 factors scale effect of regional economy, scale effect of regional energy consumption, scale effect of investment in treatment of environment pollution (ITEP), technology effect of energy efficient utilization, technology effect of clean energy utilization technology, the intensity effect of regional green economic development, the intensity effect of investment in treatment of regional PM2.5 emission, and the intensity effect of regional environmental regulation. To identify the vital driving force of the change of PM2.5 emission, the contribution of each driving factor of PM2.
