Abstract: Weather and climate conditions directly influence the occurrence and dynamics of forest fires. And when they occur in environmental preservation regions, they have impacts on biodiversity loss, climate change and water security. This study identified the synotic patterns favorable to the occurrence of hotspot in the Ecological Station Region of the Taim and Campos Neutrais, both located in the extreme south of Brazil. In the study region, humidity deficits are more important than high temperatures, differing from what is described in the literature. Three synoptic patterns were identified: the first presenting negative anomalies of temperature and humidity, established after the passage of a cold front, which has as main contribution to generate a postfrontal stability, associated with the displacement of a high pressure system. The second and third pattern (64% of wildfire) correspond to the most intense and long-lasting events, which occur in the presence of the South Atlantic Convergence Zone and Humidity Convergence Zone, respectively, and act on the northwest-southeast region of Brazil. These systems favor the slow displacement of a high pressure system over the study region, which contributes to the intensification of a stable environment, favoring moisture deficit and positive temperature anomalies in the study region. The results of this study provide an understanding of how the atmosphere influences the occurrence of wildfire in the study region, and will help in planning the minimization of the impact they can cause in an environmental preservation region

What has been the impact of Brexit on the UK economy?
Sarah Hall, University of Nottingham, considers the economic impacts of COVID-19 and the war in Ukraine from Brexit, which is critical if the economic impacts of the UK's new trading arrangements with the EU and the rest of the world are to be fully understood. There have been negative impacts on trade which can be largely separated from the impacts of COVID-19 and the War on Ukraine. Crucially, the devil is in the detail with such changes varying significantly by economic sector and by location in the UK. Whilst Brexit is only in its early stages economically, it is clear that its impacts are sectorally and regionally variegated. Explaining that examining some of these research highlights provides a valuable starting point for understanding the impact of Brexit on the UK economy, taken together, Hall's analysis suggests that the early economic impacts of Brexit on the UK economy do not neatly follow the estimates made by economists immediately following the referendum.

Brass instruments in Swedish cavalry music in the early nineteenth century – a period of transition
This article makes use of archival material – early brass scores and financial accounts – in Swedish cavalry regimental archives, providing information about the use of natural horns and trumpets and keyed instruments (keyed bugles, ophicleïdes) and about the introduction of valve brass instruments – French horns, (Swedish) cornets, horns, trombones and bass tubas – in Sweden during the first half of the nineteenth century.
Preserved Swedish cavalry scores from the early nineteenth century reflect Prussian traditions and show how recent compositions, especially pieces of opera music, were arranged by cavalry band masters and musicians, several of which were members of the Royal Orchestra and thus familiar with what was on the fore in the Swedish capital. Their instruments were of north German models, bought by band masters and musicians and copied, repaired and developed by Swedish brass workers and workshops. Keyed and natural instruments were used alongside the new valve instruments from around 1830 and well into the mid-nineteenth century.

A vízáteresztő burkolatokat egyre gyakrabban alkalmazzák városi felületek burkolataként világszerte és hazánkban egyaránt, mivel a vízzáró felületek kiváltása hozzájárul az éghajlatváltozás okozta negatív hatások mérsékléséhez. A vízáteresztő burkolatok a csapadékvíz-gazdálkodást támogató kék-zöld infrastruktúra rendszerek egyik eszközeként segíthetnek a városi vízgyűjtőre lehullott csapadékvizek visszatartásában és a talajba való beszivárogtatásában, csökkentve ezzel a lefolyó csapadékvíz mennyiségét és javítva a helyi mikroklímát.
A vízáteresztő burkolatok egyik legfontosabb tulajdonsága a felszíni vízáteresztő képességük, amely az idő előrehaladtával az őket érő szemcsés (szennyező)anyagok hatására csökkenhet. A kutatás során 18 budapesti helyszínen végeztünk in-situ beszivárgás méréseket 2020-ban és 2021-ben öntött gumi, valamint műgyantával stabilizált szórt kavicsburkolatokon. A burkolatok kora és az áteresztő képességük között erős, exponenciális kapcsolatot találtunk, mely szerint a burkolatok vízáteresztő képessége évenként nagyjából megfeleződik. Mivel a mérési módszer típusa is hatással lehet a terepi mérések eredményére, ezért a mérések során kétfajta infiltrációs tesztet hasonlítottunk össze, szimpla és dupla gyűrűset. A két módszerrel mért vízáteresztő képesség között nem találtunk egyértelmű különbséget, azonban az azonos módszerekkel végzett, ismételt vizsgálatok esetében több, a mérés megbízhatóságát befolyásoló jelenséget és hatást is vizsgáltunk, úgymint: eltömődés, kimosódás, oldalirányú elszivárgás, térbeli heterogenitás.
Socio-Economic Status of Wheat Growers in Some Selected Areas of Bangladesh
Authors: Tasnim Zarin 
Published: April 2023

Aims: The study was carried out to determine the socio-economic status of wheat farmers in Bangladesh.
Study Design: Simple random sampling technique was used for the study.
Place and Duration of the Study: Birganj Upazila under Dinajpur and Thakurgaon Sadar, and Pirganj Upazila under Thakurgaon district were purposively selected for the study. The survey was conducted from February to March 2019.
Methodology: A total of 150 wheat growers were selected as sample farmers. Data were collected from the respondents through direct interviews using pre-tested interview schedules. Descriptive statistics such as mean, frequency, and percentage were employed to analyze the data.
Results: The study estimated that the average farm size was 1.38 ha, and most of them were medium farmers (40 percent). Most of the wheat growers were middle-aged (51–60 years old), while a small portion of them were younger (18–30 years). Findings revealed that about 35.3 percent of farmers were literate, while 34.7 percent completed secondary education. The average family size was 4.96 persons. However, the large farm household had relatively more family members than other farm households. Most of the respondents had more than 30 years of farming experience. Nevertheless, agriculture, notably wheat farming, was their primary occupation (92 percent), and about 70.67 percent of their average yearly income came from agriculture. Furthermore, the study found that only a small percentage of farmers obtained training from the government's agricultural extension office, while most farmers did not receive any training opportunities. In this study, about 53.33% of respondents received loans from banks or NGOs, whereas around 46.67% received no credit.
Conclusion: Therefore, the government should provide more institutional and infrastructure support to promote wheat production, which will increase efficiency, income and enhance the livelihood conditions of wheat farmers in the study areas.

Authors: Saptorini Kriswiharsi Kun , Fani Tiara , Isworo Slamet 
Published: April 2023

Background and Objectives: The COVID-19 pandemic has severely damaged the world economy. Due to the COVID-19 infection, hospitalization is in high demand. Numerous COVID-19 patients are treated medically, released from the hospital, and then relapse and need to undergo treatment because they test positive. This places a strain on the health services, and the number of relapses is rarely reported in the literature. The purpose of the study is to assess individual and frequency-based factors that influence readmission of COVID-19 patients.
Methods: This study uses a systematic review of the literature, using the PICO strategy for the construction of the research question, the bibliographic search and the best available scientific information in the systematization.
Results: The traits of the chosen studies are compiled in Table 3. In the period from March 30, 2020, to February 23, 2021, 28 studies were published. The majority of studies were carried out in China, with Wuhan reporting the highest number. There were also some studies conducted outside of China, including one from South Korea, six from the United States specifically, one from Spain, and one from Turkey. Age 65 was a risk factor for readmission or re-positive rates, which ranged from 3.6% to 67.1%.
Conclusion: The hospital strictly controls Covid-19 patients before they are allowed to leave the hospital to prevent recurrence as a result of relapse in Covid-19 patients during the pandemic.
Externally Tunable, Low Power Electrostatic Control of Cell Adhesion with Nanometric High‐k Dielectric Films

Published: April 2023

AbstractControlling cell adhesion to surfaces is an important, but difficult, problem. Current methods to control adhesion rely on surface functionalization, which have limited material choice to avoid cell toxicity and are typically cell specific. Herein, cell adhesion is modulated by using nanometric high‐k dielectric films. Voltage is applied across the dielectric film, changing the film surface's zeta potential, ζ. High performance dielectrics, HfO2 and SiO2, enables a change in the ζ polarity and magnitude over large, 100 mV, ranges by applying ≈1 V across the dielectrics with ≈1nW power draw. Freshwater Chlorella vulgaris and saltwater Nannochloropsis oculata, which have a negative ζ, are used as model cells. Cell adhesion is observed to be inhibited when both surface and cell ζ are negative and enhanced when surface ζ is positive and cell ζ are negative using microfluidic experiments. Finally, millimetric scale cell patterning is demonstrated by spatially modulating ζ with no observed toxicity to cells over 4 weeks.

Published: April 2023

AbstractBio‐ink has gradually transited from ionic‐crosslinking to photocrosslinking due to photocurable bio‐hydrogel having good formability and biocompatibility. It is very important to understand and quantify the crosslinking process of photocurable hydrogels, otherwise, bioprinting cannot be standardized and scalable. However, there are few studies on hydrogel formation process and its photocrosslinking behavior which cannot be accurately predicted. Herein, the photoinitiated radical polymerized bio‐hydrogels are taken as an example to establish the formation theory. Three typical crosslinking reactions are first distinguished. It is further proposed that not all double‐bonds consumed during crosslinking contributeequally to polymerization. Then the concept of effective double‐bond conversion (EDBC) is elicited. Deriving from EDBC, several important formation indices are defined. According to theory, it is predicted that slow crosslinking can improve the crosslinking degree. Furthermore, based on the slow crosslinking effect, a new strategy of projection‐based 3D printing (PBP) is proposed, which significantly improved printing quality and efficiency. Overall, this work will fill the gap in hydrogel's formation theory, making it possible to accurately quantify the formation process.

AbstractInfection is a major complication associated with orthopedic implants. It often involves the development of biofilms on metal substrates, which act as barriers to the host's immune system and systemic antibiotic treatment. The current standard of treatment is revision surgery, often involving the delivery of antibiotics through incorporation into bone cements. However, these materials exhibit sub‐optimal antibiotic release kinetics and revision surgeries have drawbacks of high cost and recovery time. Herein, a new approach is presented using induction heating of a metal substrate, combined with an antibiotic‐loaded poly(ester amide) coating undergoing a glass transition just above physiological temperature to enable thermally triggered antibiotic release. At normal physiological temperature, the coating provides a rifampicin depot for >100 days, while heating of the coating accelerates drug release, with >20% release over a 1‐h induction heating cycle. Induction heating or antibiotic‐loaded coating alone each reduceStaphylococcus aureus(S. aureus) viability and biofilm formation on Ti, but the combination causes synergistic killing ofS. aureusas measured by crystal violet staining, determination of bacterial viability (>99.9% reduction), and fluorescence microscopy of bacteria on surfaces. Overall, these materials provide a promising platform enabling externally triggered antibiotic release to prevent and/or treat bacterial colonization of implants.

AbstractChemodynamic therapy is a promising tumor treatment strategy. However, it remains a great challenge to overcome the unavoidable off‐target damage to normal tissues. In this work, it is discovered that magnetoferritin (M‐HFn, biomimic peroxidase) can form nanocomplexes with glucose oxidase (GOD) in the presence of glucose, thus inhibiting the enzyme activity of GOD. Interestingly, GOD&M‐HFn (G‐M) nanocomplexes can dissociate under near‐infrared (NIR) laser, reactivating the enzyme cascade. Based on this new finding, a spatiotemporally controllable biocatalytic cascade in red blood cell (RBC) nanovesicles (G‐M@RBC‐A) is fabricated for precise tumor therapy, which in situ inhibits enzyme cascade between GOD and M‐HFn during blood circulation and reactivates the cascade activity in tumor site by NIR laser irradiation. In RBC nanovesicles, GOD is grabbed by M‐HFn to form G‐M nanocomplexes in the presence of glucose, thus inhibiting the Fenton reaction and reducing side effects. However, after NIR laser irradiation, G‐M nanocomplexes are spatiotemporally dissociated and the cascade activity is reactivated in the tumor site, initiating reactive oxygen species damage to cancer cells in vivo. Therefore, this work provides new insight into the fabrication of spatiotemporally controllable biocatalytic cascade for precise cancer therapy in the future.

AbstractGeneration, manipulation, and sensing of magnetic domain walls are cornerstones in the design of efficient spintronic devices. Half‐metals are amenable for this purpose as large low field magnetoresistance signals can be expected from spin accumulation at spin textures. Among half metals, La1−xSrxMnO3 (LSMO) manganites are considered as promising candidates for their robust half‐metallic ground state, Curie temperature above room temperature (Tc = 360 K, for x = 1/3), and chemical stability. Yet domain wall magnetoresistance is poorly understood, with large discrepancies in the reported values and conflicting interpretation of experimental data due to the entanglement of various source of magnetoresistance, namely, spin accumulation, anisotropic magnetoresistance, and colossal magnetoresistance. In this work, the domain wall magnetoresistance is measured in LSMO cross‐shape nanowires with single‐domain walls nucleated across the current path. Magnetoresistance values above 10% are found to be originating at the spin accumulation caused by the mistracking effect of the spin texture of the domain wall by the conduction electrons. Fundamentally, this result shows the importance on non‐adiabatic processes at spin textures despite the strong Hund coupling to the localized t2g electrons of the manganite. These large magnetoresistance values are high enough for encoding and reading magnetic bits in future oxide spintronic sensors.
