Se realizó un inventario de bosque en una parcela permanente de una hectárea en la Reserva Numbala, un área protegida de 1013 hectáreas, propiedad de la fundación Naturelza y Cultura Internacional (NCI), ubicada en el cantón Palanda, Zamora- Chinchipe, Ecuador, colindante con el Parque Nacional Podocarpus, a 2100 m.s.n.m., 4°24’19”S, 79°03’36”W. Se realizó el inventario de los árboles con DAP (diámetro a la altura de pecho) ≥ 5 cm. Se registró un total de 1091 árboles y 171 especies, con un área basal de 47,73 m²/ha y un volumen total de madera de 652 m3/ha. Las especies dominantes del bosque por sus diámetros y alturas son Gimnospermas, dos especies de Podocarpaceae: Retrophyllum rospigliosii y Prumnopitys harmsiana que representan 59,7% del área basal y 79,6% del volumen total del bosque en la parcela inventariada, que incluye 35 árboles de estas dos especies con diámetros mayores a 70 cm y hasta 47 m de altura. No obstante la dominancia de las dos especies de Gimnospermas, la diversidad florística es relativamente alta con 171 especies de árboles registrados, incluyendo diversas especies de Rubiaceae, Lauraceae, Meliaceae, Myrtaceae y Melastomataceae. Los valores de área basal y volumen de madera, y la cantidad de árboles grandes mayores a 70 cm DAP, son muy altos en comparación con otros bosques neotropicales. Hay evidencia bibliográfica de la existencia en el pasado de rodales grandes dominados por Podocarpaceae, particularmente de Retrophyllum rospigliosii, en otros países andinos, pero casi todos han sido talados por la extracción de madera, y el bosque de Numbala es uno de los últimos remanentes de los “bosques gigantes” de Podocarpaceae en los Andes tropicales

Published: May 2023

Gelombang elektromagnetik dapat diartikan sebagai gelombang yang terbentuk dari perpaduan medan magnetik dan medan listrik. Paparan dalam jangka waktu yang lama menyebabkan imunologis dan stres oksidatif antara lain limfosit dengan salah satu sel T yang memproduksi sitokin salah satunya adalah interleukin-2 (IL-2). Tujuan penelitian ini menganalisis pengaruh paparan gelombang elektromagnetik frekuensi radio GSM 900 MHz terhadap jumlah produksi IL-2 dengan variasi jarak dan waktu yang ditentukan. Sampel yang digunakan adalah sampel darah sehat dari 13 pendonor yang telah dikultur Peripheral Blood Mononuclear Cells (PBMC). Metode dalam penelitian ini: darah normal diberikan paparan radiasi gelombang elektromagnetik frekuensi radio GSM 900 MHz dengan menggunakan perangkat VSG25A ke sel darah putih yang telah dikultur dalam kotak aluminium yang dilapisi timbal. Variasi jarak yang diberikan, dihitung dari ujung antena perangkat VSG25A dengan wadah sampel adalah 0 cm, 2.5 cm, dan 5 cm dan waktu paparan selama 15, 30, 45, dan 60 menit. Semua sampel yang diberikan paparan maupun tidak diberikan paparan (normal) dihitung jumlah Interleukin-2 menggunakan flowcytometry. Hasil penelitian menunjukkan bahwa semakin lama paparan gelombang elektromagnetik frekuensi radio GSM 900 MHz, produksi IL-2 cenderung meningkat. Pada jarak 2,5 cm produksi IL-2 menurun setelah diberikan paparan selama 30 menit. Sedangkan produksi IL-2 terhadap jarak paparan apabila lama paparan kurang dari 30 menit dapat diartikan tidak ada pengaruh yang signifikan terhadap perubahan jumlah produksi IL-2.

Aims: To develop slow release fertilizer formulations using humic acid, charcoal and zeolite and to evaluate nutrient availability, nutrient use efficiency and yield in chilli.
Study Design: This experiment was conducted through completely randomized design with 14 treatments and 3 replications.
Place and Duration of Study: The research was appraised at the Department of Soil Science, College of Agriculture, Vellayani between September 2022- December 2022.
Methods: Carbon and zeolite based slow release fertilizer formulations (SRF) containing all the major, secondary and micronutrients were prepared using compatible fertilizer materials (urea, rajphos, muriate of potash, phosphogypsum, magnesium sulphate, zinc sulphate and borax), carrier materials (zeolite, humic acid and charcoal) and the binding agent (carboxy methyl cellulose) in the ratio of 1:1 and 1: 0.5 in the form of pellets. These formulations were applied to chilli and evaluated nutrient use efficiency and yield.
Results: The pellets were highly stable and weight ranged between 4.0 and 4.5 g. The highest fruit yield of chilli observed was 581.2 g/ plant. The available nitrogen (320.86 kg ha-1), phosphorus (87.15 kg ha-1), potassium (214.35 kg ha-1), calcium (351.13 mg kg-1), magnesium (106.54 mg kg-1), sulphur (9.32 mg kg- 1), boron (0.46 mg kg-1) and zinc (4.25 mg kg-1) was found to be highest in treatment receiving 75% recommended dose of fertilizers (RDF) as humic acid based slow release formulation applied in two splits (basal and 1 MAP). The apparent recovery percentage of nitrogen 78.2%, phosphorus 86.33% and potassium 98.70% and partial factor productivity of 25.98 g g-1 were recorded due to the application of pellets.
Conclusion: Carbon and zeolite based slow release fertilizer formulations in the form of pellets are very effective compared to conventional fertilizers due to their gradual pattern of nutrient release which better meets plant demand, minimizes leaching and therefore nutrient use efficiency and ultimately crop yield. Application of slow release formulations significantly increases the nutrient availability in soil, nutrient use efficiency, growth and yield of chilli.

ImportanceAsymptomatic blood pressure (BP) elevations are common in hospitalized older adults, and widespread heterogeneity in the clinical management of elevated inpatient BPs exists.ObjectiveTo examine the association of intensive treatment of elevated inpatient BPs with in-hospital clinical outcomes of older adults hospitalized for noncardiac conditions.Design, Setting, and ParticipantsThis retrospective cohort study examined Veterans Health Administration data between October 1, 2015, and December 31, 2017, for patients aged 65 years or older hospitalized for noncardiovascular diagnoses and who experienced elevated BPs in the first 48 hours of hospitalization.InterventionsIntensive BP treatment following the first 48 hours of hospitalization, defined as receipt of intravenous antihypertensives or oral classes not used prior to admission.Main Outcome and MeasuresThe primary outcome was a composite of inpatient mortality, intensive care unit transfer, stroke, acute kidney injury, B-type natriuretic peptide elevation, and troponin elevation. Data were analyzed between October 1, 2021, and January 10, 2023, with propensity score overlap weighting used to adjust for confounding between those who did and did not receive early intensive treatment.ResultsAmong 66 140 included patients (mean [SD] age, 74.4 [8.1] years; 97.5% male and 2.6% female; 17.4% Black, 1.7% Hispanic, and 75.9% White), 14 084 (21.3%) received intensive BP treatment in the first 48 hours of hospitalization. Patients who received early intensive treatment vs those who did not continued to receive a greater number of additional antihypertensives during the remainder of their hospitalization (mean additional doses, 6.1 [95% CI, 5.8-6.4] vs 1.6 [95% CI, 1.5-1.8], respectively). Intensive treatment was associated with a greater risk of the primary composite outcome (1220 [8.7%] vs 3570 [6.9%]; weighted odds ratio [OR], 1.28; 95% CI, 1.18-1.39), with the highest risk among patients receiving intravenous antihypertensives (weighted OR, 1.90; 95% CI, 1.65-2.19). Intensively treated patients were more likely to experience each component of the composite outcome except for stroke and mortality. Findings were consistent across subgroups stratified by age, frailty, preadmission BP, early hospitalization BP, and cardiovascular disease history.Conclusions and RelevanceThe study’s findings indicate that among hospitalized older adults with elevated BPs, intensive pharmacologic antihypertensive treatment was associated with a greater risk of adverse events. These findings do not support the treatment of elevated inpatient BPs without evidence of end organ damage, and they highlight the need for randomized clinical trials of inpatient BP treatment targets.
The formation of “form” and the “decoration” of space in Charlotte Perriand, part 1: Theory and practice of “en Forme (in shape)”
Authors: Sendai Shoichiro 
Published: May 2023

AbstractThis paper aims to clarify the formation process of the concept of “form” from the 1920s to the 1930s by chronologically tracing the creation of Perriand's furniture. That is, by analyzing the key terms “equipment,” “art brut” and “en forme (in shape),” this paper examines how the generation and transformation of steel pipe furniture as “form,” which was considered “new decoration.” When Perriand pursued the possibilities of “form,” the dualisms of industrial and natural materials were not at issue. When she sought in form to induce and “control” a gesture, the geometrical form limited and inhibited it. “En forme” was to liberate the threshold of gesture that form defines. Being “controlled” by the matter, rather than “controlled” by humans, could give rise to unexpected uses. It was the practice of her “new decoration,” a development of Le Corbusier's concept of “equipment” as the kind of interior “decoration” to regulate the typological gestures of humans.

AbstractThe high reliability and proven ultra‐longevity make aqueous hydrogen gas (H2) batteries ideal for large‐scale energy storage. However, the low alkaline hydrogen evolution and oxidation reaction (HER/HOR) activities of expensive platinum catalysts severely hamper their widespread applications in H2 batteries. Here, cost‐effective, highly active electrocatalysts, with a model of ruthenium‐nickel alloy nanoparticles in ≈3 nm anchored on carbon black (RuNi/C) as an example, are developed by an ultrafast electrical pulse approach for nickel‐hydrogen gas (NiH2) batteries. Having a competitive low cost of about one fifth of Pt/C benckmark, this ultrafine RuNi/C catalyst displays an ultrahigh HOR mass activity of 2.34 A mg−1 at 50 mV (vs RHE) and an ultralow HER overpotential of 19.5 mV at a current density of 10 mA cm−2. As a result, the advanced NiH2 battery can efficiently operate under all‐climate conditions (from −25 to +50 °C) with excellent durability. Notably, the NiH2 cell stack achieves an energy density up to 183 Wh kg−1 and an estimated cost of ≈49 $ kWh−1 under an ultrahigh cathode Ni(OH)2 loading of 280 mg cm−2 and a low anode Ru loading of ≈62.5 µg cm−2. The advanced beyond‐industrial‐level hydrogen gas batteries provide great opportunities for practical grid‐scale energy storage applications.

Published: May 2023

AbstractValence tuning of transition metal oxides is an effective approach to design high‐performance catalysts, particularly for the oxygen evolution reaction (OER) that underpins solar/electric water splitting and metal‐air batteries. Recently, high‐valence oxides (HVOs) are reported to show superior OER performance, in association with the fundamental dynamics of charge transfer and the evolution of the intermediates. Particularly considered are the adsorbate evolution mechanism (AEM) and the lattice oxygen‐mediated mechanism (LOM). High‐valence states enhance the OER performance mainly by optimizing the eg‐orbital filling, promoting the charge transfer between the metal d band and oxygen p band. Moreover, HVOs usually show an elevated O 2p band, which triggers the lattice oxygen as the redox center and enacts the efficient LOM pathway to break the “scaling” limitation of AEM. In addition, oxygen vacancies, induced by the overall charge‐neutrality, also promote the direct oxygen coupling in LOM. However, the synthesis of HVOs suffers from relatively large thermodynamic barrier, which makes their preparation difficult. Hence, the synthesis strategies of the HVOs are discussed to guide further design of the HVO electrocatalysts. Finally, further challenges and perspectives are outlined for potential applications in energy conversion and storage.

AbstractThe purpose of this study was to describe the characteristics of published international literature using the Japan Trauma Data Bank (JTDB). We undertook a scoping review of studies using data from JTDB. We carried out a systematic search of the following databases on November 21, 2022, using search terms that covers trauma registries in Japan: MEDLINE, Web of Science, CINAHL, and Cochrane Library. Two authors independently abstracted the data. We included all original articles written in English. We identified 166 studies from the 456 included articles. From 2010 to 2016, the annual number of published articles was less than 10. In 2017, there were 10 articles published (6.0%). This increased to 18 (10.8%) in 2018, 21 (12.7%) in 2019, 28 (16.9%) in 2020, 33 (19.9%) in 2021, and 37 (22.3%) in 2022. Most articles (n = 138, 83.1%) reported in‐hospital mortality as the primary outcome. There were more articles on the adult population (n = 86, 51.8%) than those on the pediatric population (n = 21, 12.7%). Twenty‐one articles (12.7%) specified a mechanism of injury for the study population, and three articles (1.8%) focused on burns. Most articles did not specify injury sites for the study population (n = 108, 65.1%) and the most common injury site described in publications was the head (n = 21, 12.7%), followed by the abdomen (n = 13, 7.8%). We observed an increase in international publications using the JTDB and highlighted the major topics and knowledge gaps. Our findings could encourage studies to explore less studied areas in research using the JTDB.

Published: May 2023

AbstractThe (stereoselective) living coordinative copolymerization of 1‐alkenes with 4‐aryl‐1,6‐heptadienes, in both the absence and presence of multiple equivalents of a reversible chain transfer agent, is established as a highly versatile strategy for production of multivariate hyperdimensional functionalized semi‐crystalline or amorphous polyolefins that optionally possess either mono‐ or difunctionalized (telechelic) end‐groups in combination with a programmable level of incorporation of orthogonal functional groups within the main‐chain. The non‐conjugated diene comonomers are readily obtained from a diverse range of aryl carboxaldehyde precursors through a one‐step bis‐allylation process. These results serve to provide a new platform for exploring the science and technology of a vast new landscape of functionalized classes of polyolefins that are now accessible in practical and scalable quantities.

AbstractPursuing high power density lithium metal battery with high safety is essential for developing next‐generation energy‐storage devices, but uncontrollable electrolyte degradation and the consequence formed unstable solid‐electrolyte interface (SEI) make the task really challenging. Herein, an ionic liquid (IL) confined MOF/Polymer 3D‐porous membrane was constructed for boosting in situ electrochemical transformations of Janus‐heterarchical LiF/Li3N‐rich SEI films on the nanofibers. Such a 3D‐Janus SEI‐incorporated into the separator offers fast Li+ transport routes, showing superior room‐temperature ionic conductivity of 8.17×10−4 S cm−1 and Li+ transfer number of 0.82. The cryo‐TEM was employed to visually monitor the in situ formed LiF and Li3N nanocrystals in SEI and the deposition of Li dendrites, which is greatly benefit to the theoretical simulation and kinetic analysis of the structural evolution during the battery charge and discharge process. In particular, this membrane with high thermal stability and mechanical strength used in solid‐state Li||LiFePO4 and Li||NCM‐811 full cells and even in pouch cells showed enhanced rate‐performance and ultra‐long life spans.
