Published: April 2022

Trioxane, a cyclic trimer of formaldehyde, is an important intermediate that is mainly used as a source of water-free formaldehyde in chemical production processes. Different routes for the production of trioxane from aqueous formaldehyde solutions have been described in the literature, which all have in common that they are energy-intensive. In this work, the conceptual design of a new production process for trioxane is presented. It is a modification of a state-of-the-art pressure swing process from the literature, where the most critical distillation step is replaced with a crystallization. The new crystallization-based process and the pressure swing process were simulated in a consistent manner based on a well-established physico-chemical model for the ternary system (formaldehyde + water + trioxane). To obtain a sound basis for the description of the crystallization, solid–liquid equilibria in the ternary system, for which previously no data was available, were measured at conditions relevant for the process. A comparison of the two processes showed that the new crystallization-based process has a considerably reduced energy demand and much smaller recycle streams. Furthermore, it was found that the crystallization can be performed efficiently at temperatures well above 273 K. All this makes the new crystallization-based process an attractive candidate for trioxane production.

BACKGROUND: The COVID-19 pandemic has disrupted regular health care with potential consequences for non-COVID diseases like cancer. To ensure continuity of oncological care, guidelines were temporarily adapted. OBJECTIVE: To evaluate the impact of the COVID-19 outbreak on bladder cancer care in the Netherlands. METHODS: The number of bladder cancer (BC) diagnoses per month during 2020-2021 was compared to 2018-2019 based on preliminary data from the Netherlands Cancer Registry (NCR). Additionally, detailed data were retrieved from the NCR for the cohort diagnosed between March 1st-May 31st 2020 (first COVID wave) and 2018-2019 (reference cohort). BC diagnoses, changes in age and stage at diagnosis, and time to first-line treatment were compared between both periods. Changes in treatment were evaluated using logistic regression. RESULTS: During the first COVID wave (week 9–22), the number of BC diagnoses decreased by 14%, corresponding with approximately 300 diagnoses, but increased again in the second half of 2020. The decline was most pronounced from week 13 onwards in patients≥70 years and patients with non-muscle invasive BC. Patients with muscle-invasive disease were less likely to undergo a radical cystectomy (RC) in week 17–22 (OR = 0.62, 95% CI = 0.40–0.97). Shortly after the start of the outbreak, use of neoadjuvant chemotherapy decreased from 34% to 25% but this (non-significant) effect disappeared at the end of April. During the first wave, 5% more RCs were performed compared to previous years. Time from diagnosis to RC became 6 days shorter. Overall, a 7% reduction in RCs was observed in 2020. CONCLUSIONS: The number of BC diagnoses decreased steeply by 14% during the first COVID wave but increased again to pre-COVID levels by the end of 2020 (i.e. 600 diagnoses/month). Treatment-related changes remained limited and followed the adapted guidelines. Surgical volume was not compromised during the first wave. Altogether, the impact of the first COVID-19 outbreak on bladder cancer care in the Netherlands appears to be less pronounced than was reported for other solid tumors, both in the Netherlands and abroad. However, its impact on bladder cancer stage shift and long-term outcomes, as well as later pandemic waves remain so far unexamined.

BACKGROUND: Studies of coactivation have typically utilized single movement isometric or isokinetic fatiguing muscle actions. OBJECTIVE: The purpose of the current study was to examine coactivation of the biceps brachii (BB) and triceps brachii (TB) in response to a maximal, reciprocal, isokinetic fatiguing task of the forearm flexors and extensors at slow (60[Formula: see text]/s) and moderate (180[Formula: see text]/s) isokinetic velocities in men. METHODS: Ten men (mean [Formula: see text] SD: age [Formula: see text] 21.6 [Formula: see text] 1.3 years) completed 50 consecutive, maximal, reciprocal, isokinetic muscle actions of the right forearm flexors and extensors at 60 and 180[Formula: see text]/s. The amplitude (AMP) and mean power frequency (MPF) contents of the electromyographic (EMG) and mechanomyographic (MMG) signals from the BB and TB were recorded simultaneously throughout the fatiguing task. Repeated measures ANOVAs with Tukey post hocs were used to determine mean differences for the torque and neuromuscular parameters across repetitions. RESULTS: The torque analyses indicated greater fatigability at 180[Formula: see text]/s, compared to 60[Formula: see text]/s ([Formula: see text] 0.02). There were no significant changes in EMG AMP for either muscle during flexion or extension at 60[Formula: see text]/s ([Formula: see text] 0.05). At 180[Formula: see text]/s, there were significant increases in agonist EMG AMP ([Formula: see text] 0.01 to 0.004), however, no changes in antagonist EMG AMP ([Formula: see text] 0.05). For EMG MPF, there were significant decreases during flexion and extension ([Formula: see text] 0.001 to [Formula: see text] 0.02) at both velocities, collapsed across muscle. There were no significant ([Formula: see text] 0.05) changes across repetition for MMG AMP or MPF. CONCLUSIONS: This study indicated velocity-specific responses to fatigue, with a greater magnitude of fatigability at 180[Formula: see text]/s. Furthermore, despite increases in EMG AMP of the agonist muscles at 180[Formula: see text]/s only, it was not sufficient to alter the ratio of coactivation, likely due to common neural drive between muscles. Thus, the decreases in torque in the present study were not attributable to increases in coactivation.

BACKGROUND: Reduced mobility of upper and lower limbs has been associated with injuries in athletes. The Combined Elevation Test (CET) and the Weight-Bearing Dorsiflexion Lunge Test (WBDLT) are frequently used in clinical and research settings in face-to-face evaluations. However, some situations require physical distancing, and it is unknown whether those tests via telehealth are reliable. OBJECTIVE: To evaluate the intra-rater reliability, the Standard Error of Measurement (SEM), and the Minimum Detectable Change (MDC) for considering a real change on the CET and WBDLT were calculated for healthy athletes via telehealth. METHODS: 67 athletes (25 years, 73 kg, and 1.75 m on average) participated in this study. 37 athletes performed the CET and 50 performed the WBDLT (20 performed both tests). Reliability was assessed through two online evaluations (7 to 15-days apart). RESULTS: ICC[Formula: see text] ranged from 0.88–0.97 for the CET and from 0.95–0.98 for the WBDLT. For both tests, SEM values were low ([Formula: see text] 8.9%) and the MDC[Formula: see text] was approximately 4 cm and 2 cm for the CET and WBDLT, respectively. CONCLUSIONS: Telehealth-based findings relating to CET and WBDLT are reliable in healthy adult athletes and can be used to screen this population when face-to-face evaluations are not feasible.

BACKGROUND: There is consumer interest in berries due to their nutritional properties, especially biologically active compounds. Spray drying technologies improve products stability and shelf life, and the agglomeration process subsequently enhances powder instantaneousness and flow properties. OBJECTIVE: The aim was to evaluate the effect of the fluidized bed agglomeration process on flow, reconstitution, and antioxidant properties of cape gooseberry, strawberry, and blackberry powder mix obtained by spray drying and a water and vitamin C binding solution. METHODS: A face-centered central composite design with 15 experiments was used; independent variables were fluidization temperature (T), binder solution atomization pressure (P), and process time (t), while dependent variables were moisture, solubility, wettability, particle size, antioxidant capacity, total phenols, Vit. C, β-carotenes (β-car), and total anthocyanins. RESULTS: The best process conditions from experimental optimization were T = 70 °C, P = 1.1 bar, and t = 29.1 min. This agglomerated product had low moisture values, good solubility, and 0.5 min wettability; the values for Vit. C = 246.4±3.4 mg/100 g db, β-car = 4.0±0.5 mg/100 g db, and total anthocyanins = 230.7±3.0 mg C3G/100 g db were noteworthy. CONCLUSIONS: An agglomerate berry-based powder product was obtained with 100% Vit. C RDA (Recommended Dietary Allowances) and 15% vitamin A RDA. Flow and instantaneousness properties of the agglomerated powder also significantly improved with the applied process.
MANGROVE RESTORATION IN NE BRAZIL: A UNIFIED CONTRIBUTION TO ADAPTING TO GLOBAL CLIMATE CHANGE
Authors: Cesar Ferreira Alexander , Drude de Lacerda Luiz 
Published: April 2022

The decade 2021-2030 was defined by the UN as the decade of ‘Ecosystem Restoration’ and of ‘Ocean Science for Sustainable Development’, aiming to restore ecosystems and protect the Oceans. Among target ecosystems, mangroves are fundamental wetlands, since they support a lively, biologically dynamic frontier between land and sea, furnishing many goods and services in relation to their extension, like fisheries, timber, biodiversity conservation and climate change mitigation, among others. Regarding climate change, mangrove restoration helps mitigate GHG emissions, by sequestering carbon in biomass and sediments for long periods of time and increases shore protection facing sea level rise and extreme climate events. The possibilities and conditions for mangrove restoration are many, and their rehabilitation/restoration is possible as provided by evidence form many experiments worldwide. Notwithstanding, there are still many steps in methodology and governance decisions to place mangrove restoration as a globally effective mitigation and adaptation measure to climate change.

CLIMATE CHANGE PERSPECTIVES OF THE CYCLONES AND OCEANIC HAZARDS IN THE WESTERN SOUTH ATLANTIC OCEAN
Authors: Barnez Gramcianinov Carolina , M. Campos Ricardo , De Camargo Ricardo 
Published: April 2022

Cyclone-related oceanic hazards, such as extreme waves and surges, are frequently reported on the western South Atlantic. These events are associated with coastal erosion, coastal infrastructure damage, maritime navigation, and offshore industry incidents, being important for safety and maintenance management in ocean engineering. Present climate trends and future projections of this event are frequently linked with the expected general poleward shift of the storm track over the globe, but regional approaches revealed a slight increase in the cyclonic activity in South America 35ºS and 40ºS, which would be restricted to the coast. However, the signals of these changes are weak and frequently of the same magnitude of model biases, producing results with a lack of confidence, especially in the coastal zone. Extreme events related to waves and surges used to present large uncertainty and heterogeneity around the globe. Most of the problems regarding future estimation rely on methodological limitations that will not overrun without collaborative efforts to the improvement of observational-based science. Taking advantage of the UN Ocean Decade goals, national and regional initiatives need to collaborate towards a robust and continuous Brazilian observational network in order to face the climate crises in the country.

OCEAN MODELLING IN BRAZIL, A QUICK OVERVIEW
Authors: Marta-Almeida Martinho 
Published: April 2022

Hydrodynamic numerical modelling studies, at least partially focused on the Brazilian oceanography, were identified using the Scopus database. Ocean modelling in Brazil started in 1994 and has been increasing especially since 2007. In recent years, however, the rate of the increase is slowing. The main ocean models used are ROMS, POM and HYCOM, and the main institutions publishing in ocean modelling in Brazil are located in the states of São Paulo and Rio de Janeiro, resulting in the Southeast as the most studied region. Men dominate the ocean modelling in Brazil, with only three women in the top twenty scientists. Oil industry is a great sponsor of oceanography in Brazil. The interest in renewable energy offshore is, on the other hand, very low, with only two publications assessing the potential for renewable energy extraction from the ocean.

Published: April 2022

This study aims to examine the effect of good corporate governance and company characteristics on environmental disclosure. Good corporate governance is represented by the variable size of the board of commissioners, independent commissioners, and the audit committee. Meanwhile, company characteristics are represented by size and age variables. This research is a quantitative research. The data taken is secondary data. The data in this study were obtained using library research. The population in this study are companies listed on the BURSA EFEK INDONESIA (BEI) in the period 2015 - 2020. The research sample taken is companies that are included in the natural resources sector and collected using purposive sampling method. A total of 6 companies were determined as the research sample. The data analysis method in this study uses a statistical scientific approach. The analytical method used is multiple regression analysis consisting of classical assumption test (normality test, multicollinearity test, heteroscedasticity test, and autocorrelation test) and hypothesis testing (coefficient of determination, t test, F test). The results of this study indicate that the adjusted R2 value is 98.9% which means that the environmental disclosure variable can be explained by the five independent variables, namely the board of commissioners (DK), independent commissioners (KOMIN), audit committee (KOAU), size (SIZE), and age (AGE). The results of the t-test of this study indicate that: the board of commissioners, independent commissioners, audit committees, size, age have a positive effect on environmental disclosure. While the results of the F test from this study prove that the board of commissioners, independent commissioners, audit committee, size, age have a simultaneous effect on environmental disclosure.
La distinción entre esclarecimiento probatorio y esclarecimiento preparatorio en el proceso civil
Authors: Vogt Geisse Thomas Franz 
Published: April 2022

<p>Este trabajo propone adoptar la distinción entre esclarecimiento probatorio y esclarecimiento preparatorio en la reflexión comparada sobre el proceso civil. Se trata de una distinción funcional de normas procesales dirigidas al esclarecimiento de los hechos. Permite identificar normas dirigidas a formar la decisión fáctica del juzgador (esclarecimiento probatorio) y distinguirlas de normas dirigidas a proporcionar a las partes el conocimiento suficiente para comprender la fuerza de sus posiciones y tomar decisiones informadas antes de avanzar a la etapa probatoria (esclarecimiento preparatorio). Se demostrará que la confusión de estas categorías podría llevar una comprensión defectuosa del esclarecimiento preliminar del pre-trial anglosajón. A modo de ilustración, se mostrará que la <em>Rule </em>102 de las Reglas Europeas de Proceso Civil ofrece un ejemplo de cómo conservar los beneficios del intercambio de información del <em>pre-trial </em>de una forma compatible con la estructura procesal continental.<span class="Apple-converted-space"> </span></p>

Restricción del crecimiento fetal intrauterino (RCIU), es una circunstancia clínica en la cual el feto no expresa su potencial genético de crecimiento y como resultado final ocurre una disminución en el peso corporal, el cual queda por debajo del percentil 10 para la edad gestacional, en una curva de crecimiento seleccionada. La prevalencia global de RCIU según distintos autores varía entre 3,7% a 22,4%. En el Perú se reportan del 4,8% al 10,1%. Los factores obstétricos asociados a RCIU destacan: preeclampsia con OR=1,69 al OR=66,4; anemia durante la gestación OR=2,18 al OR=9,70; RCIU previa con OR=3,26 al OR=14,49 y parto pretérmino con OR=3,58 al OR=14,60.
