Published: August 2024

Gentrificação, um processo complexo relacionado ao turismo, cruza-se com a segregação socioespacial e educacional, emergindo como um fenômeno complexo e preocupante, criando a necessidade de um estudo aprofundado e contextualizado. Dessarte, este estudo se propõe a analisar o tema no contexto brasileiro, buscando entender como a gentrificação tem agravado as divisões entre os diferentes grupos sociais, prejudicado o acesso à educação e levado famílias de baixa renda para as periferias. A essência dessa problemática reside na compreensão dos mecanismos pelos quais a gentrificação afeta a estruturação socioespacial das cidades brasileiras e interfere nos sistemas educacionais locais. Nesse sentido, a pesquisa visa não apenas diagnosticar os desafios impostos por esse fenômeno, mas também apresentar estratégias e políticas públicas que promovam a equidade e a inclusão social. Inicialmente, discute-se o conceito de gentrificação e suas principais características, seguido por uma análise das formas como a gentrificação contribui para a segregação socioespacial e educacional nas cidades brasileiras. São abordados casos específicos de gentrificação em diferentes regiões do Brasil, destacando suas implicações para a distribuição desigual de recursos e oportunidades educacionais. Além disso, são discutidas políticas públicas e estratégias de intervenção necessárias para mitigar os efeitos negativos da gentrificação e promover uma maior equidade sócio espacial e educacional. Para tal será feito uma revisão de literatura, examinando estudos sobre o tema publicados a priori; estudo de caso, selecionando cidades brasileiras gentrificadas para análise de como ocorreu o fenômeno e suas consequências e; finalmente, uma análise qualitativa, avaliando padrões de gentrificação e segregação nestas cidades. Através desse enfoque multidisciplinar, busca-se não apenas diagnosticar os desafios impostos por esse fenômeno, mas também contribuir com informações para o desenvolvimento de abordagens mais inclusivas e equitativas no planejamento urbano e na promoção da educação no contexto brasileiro que possam ajudar a minimizar as segregações aqui discutidas, assim, servindo de base para estudos futuros mais aprofundados sobre o tema proposto.

Aims: The present study was conducted in four different districts of Chhattisgarh, viz. Durg, Raipur, Rajnandgaon and Dhamtari, to study the prevalence of E. coli associated diarrhoea in goats.
Study Design: Field study.
Place and Duration of Study: Faecal samples from diarrhoeic goats were collected from 04 different districts of Chhattisgarh (Durg, Raipur, Rajnandgaon and Dhamtari) during June 2023 to May 2024.
Methodology: A total of 200 faecal samples were collected from diarrhoeic goats and screened for the presence of E. coli. The faecal samples were processed for microbiological isolation and identification of E. coli isolates based on the cultural, morphological and biochemical characteristics.
Results: The overall prevalence of E. coli associated diarrhoea in goats was 72% (n = 144/200). The study indicated a higher prevalence in Dhamtari (32.64%), while the least prevalence was recorded in Rajnandgaon (16.67%). Younger goats (57.64%) were more frequently affected as compared to adult ones (42.36%). The study also revealed a greater prevalence in female goats (61.11%) than male goats (38.89%). E. coli was more prevalent in diarrhoeic goats, during the summer season (45.83%), followed by rainy season (32.64%) and winter season (21.53%). Based on breed, the higher prevalence was observed in the Anjori breed (35.42%). Goats reared with poor hygienic conditions (54.86%) were more commonly affected than goats reared under moderate (34.03%) and good (11.11%) hygienic conditions.
Conclusion: The study concludes that E. coli associated diarrhoea is highly prevalent among goats, affecting 72% of those tested. Younger and female goats, particularly in Dhamtari and reared under poor hygiene, were most commonly affected. Seasonal variations also revealed a higher prevalence in summer season. Further studies are warranted in relation to the various serotypes and zoonotic potential of E. coli responsible for diarrhoea in goats. Possible variations in more diverse geographic zones need to be explored to propose an effective control and preventive protocol against E. coli associated diarrhoea in goats, which will eventually reduce the loss in terms of health and production in goats as well as the financial losses caused to the goat rearers.

Rice sheath blight is one of the most economically important rice diseases in the world. Sheath blight, a soil-borne disease caused by the fungus Rhizoctoniasolani AG1-IA (Teleomorph: Thanatephoruscucumeris (Frank) Donk), is a devastating disease. The disease leads to a significant drop in grain yield and quality and yield losses of up to 50% have been reported under the most favorable circumstances. Despite farmers' chemical control measures against the disease, pathogen causes serious early crop losses every year. KVK Srikakulam conducted on farm trials on Sheath blight management in paddy fields to inform farmers about new and highly effective chemicals during Kharif, 2020 and 2021. A recent new chemical, Azoxystrobin 11% + Tebuconazole 18.3% (T1) at 1.5 ml/l was effective in reducing the incidence of the disease, recorded 88.2% and 81% disease incidence during 2020 and 2021, respectively. Trifloxystrobin 11% + tebuconazole 75% (T2) at 0.4 g/l was also comparable to T1, registering disease incidence of 82% and 75% in 2020 and 2021, respectively. Whereas, in the Propiconazole 11.4% @ 1.0ml/l treatment (Farmers method), the incidence in 2020 was only 67.0% and the incidence in 2021 was 65.0%. Azoxystrobin 11% + Tebuconazole 18.3% treated plots produced higher yields compared to farmers' practices. Although the chemical is more expensive than what farmers typically use, disease incidence is significantly reduced after just one spray and results in higher product yields.

Background: Anti-TNF agents have emerged not only as inducers of remission but have also shown clinical efficacy in the maintenance of remission in patients suffering from Inflammatory Bowel Disease. However, there is limited quantitative evidence of their effectiveness in Crohn’s Disease.
Aim: The current study aims to investigate the relative efficacy of anti-TNF agents in inducing and maintaining remission in Crohn’s Disease, by systematically evaluating efficacy outcomes, such as CDAI, SES-CD, and TEAEs.
Methods: A number of digital databases were searched to retrieve relevant literature. This included PubMed, Google Scholar, Cochrane, ClinicalTrials.gov. The PICOS framework was used to systematically select the data. We used the PRISMA framework to synthesize and report the relevant data.
Results: A total of 10 randomized control trials were included in the final sample. Among the anti-TNF agents, adalimumab and infliximab were most frequently used for disease control. Anti-TNF drugs were positively associated with clinical remission OR= 1.31 (95% CI (0.69, 2.10)), p<0.02; improved SES-CD scores (>50% reduction in endoscopic lesions), 1.65 (95% CI (1.44, 1.87)), p<0.0001; sustained CD remission significantly, -25.65 (95% CI (-33.22, -18.07)), p<0.001; and showed a relatively insignificant impact in lowering the incidence of treatment-emergent adverse effects 0.84 (95% CI (0.69, 1.03)), p=0.10.
Conclusion: Infliximab and adalimumab should be taken into consideration as first-line alternatives for maintaining remission in Crohn's disease due to their better efficacy and set-up safety profiles.

This study investigates and compares the effects of Neem leaf (NL) and coconut husk (CCH) adsorbents in reducing the levels of heavy metal concentration and elemental content in wastewater from two specific abandoned gold mining sites, namely Iponda (Iponda wastewater- IPWW) (longitude 4°43'18''E, Latitude 7°43'57''N ) and Idominasi (Idominasi wastewater -IDWW) (longitude 4°42'0''E, Latitude 7°40'59''N).
Preparation of locally sourced adsorbents, bioremediation process through adsorption and physico-chemical analysis of the treated wastewater samples were carried out. Adsorbents were prepared from washed, air-dried neem leaves, grinded to 40 microns size to facilitate penetration of the adsorbate. In addition, washed and airdried CCH was carbonized in an electric muffle furnace at between 300 0C and 350 0C over a period of 30 minutes, and then granulated and sieved with a mesh size of 40 µm to ensure uniform size. Measured dosages of adsorbent (0.5 g, 0.75 g, and 1 g) were added to a 50 ml volume of wastewater and the mixture was agitated at different speeds ranging from 30 rpm to 120 rpm. The treated wastewater samples were then subjected to various physico-chemical analytical tests to determine the effect of the adsorbents on the reduction of the heavy metal concentration and elemental content of the wasted water samples. The results of this study demonstrate that both NL and CCH adsorbents have a significant impact on the wastewater from the two abandoned gold mining sites, IPWW and IDWW. This impact is reflected in the reduction of heavy metal and other element concentrations in the wastewater. Furthermore, it can be concluded that the bioremediation process is more effective when utilizing NL compared to carbonized CCH. Locally sourced cheap non-edible biomass materials hitherto considered as wastes have proved to be highly effective and efficient when used as adsorbents in the treatment of wastewater from abandoned gold mining sites. This is evident from the results obtained from this study.
The statistical difference between bending arcs and regular polar arcs

Published: November 2015

AbstractIn this work, the Polar UVI data set by Kullen et al. (2002) of 74 polar arcs is reinvestigated, focusing on bending arcs. Bending arcs are typically faint and form (depending on interplanetary magnetic field (IMF) By direction) on the dawnside or duskside oval with the tip of the arc splitting off the dayside oval. The tip subsequently moves into the polar cap in the antisunward direction, while the arc's nightside end remains attached to the oval, eventually becoming hook‐shaped. Our investigation shows that bending arcs appear on the opposite oval side from and farther sunward than most regular polar arcs. They form during By‐dominated IMF conditions: typically, the IMF clock angle increases from 60 to 90° about 20 min before the arc forms. Antisunward plasma flows from the oval into the polar cap just poleward of bending arcs are seen in Super Dual Auroral Radar Network data, indicating dayside reconnection. For regular polar arcs, recently reported characteristics are confirmed in contrast to bending arcs. This includes plasma flows along the nightside oval that originate close to the initial arc location and a significant delay in the correlation between IMF By and initial arc location. In our data set, the highest correlations are found with IMF By appearing at least 1–2 h before arc formation. In summary, bending arcs are distinctly different from regular arcs and cannot be explained by existing polar arc models. Instead, these results are consistent with the formation mechanism described in Carter et al. (2015), suggesting that bending arcs are caused by dayside reconnection.

AbstractMErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) magnetometer data was surveyed between 0.3 and 0.7 AU from 6 June 2007 to 23 March 2011 for low‐frequency wave (LFW) storms, when the magnetometer was sampling at a rate of at least 2 s−1. A total of 12,197 LFW events were identified, of which 5506 lasted 10 min or longer. The events have a high degree of polarization, are circularly polarized, with wave vectors nearly aligned or antialigned with the interplanetary magnetic field (IMF) at frequencies in the vicinity of the proton cyclotron frequency. These events are observed about 6% of the time, preferentially associated with radially directed inward or outward IMF. Their occurrence rate and median duration do not change much with R, where R is the heliocentric radial distance. For a narrow‐frequency window in the solar wind frame, left‐handed storms in the spacecraft frame have a power drop off that is roughly proportional to R−3 which is consistent with a source close the Sun, while right‐handed storms have a power drop off roughly proportional R−1 which is not consistent with a source close to the Sun. The power in the left‐handed LFW storms is on average greater than the right‐handed ones by a factor of 3. In the solar wind frame, the wave frequency decreases from 0.13 to 0.04 Hz moving from 0.3 to 0.7 AU, but the frequency normalized by the local proton cyclotron frequency does not change much with the running median varying from 0.35 to 0.5. The normalized frequency band widths of the wave power spectra increase slightly with R, possibly associated with energy dissipation.

AbstractThis paper examines two internal lee wave closures that have been used together with ocean models to predict the time‐averaged global energy conversion rate into lee waves and dissipation rate associated with lee waves and topographic blocking: the Garner (2005) scheme and the Bell (1975) theory. The closure predictions in two Southern Ocean regions where geostrophic flows dominate over tides are examined and compared to microstructure profiler observations of the turbulent kinetic energy dissipation rate, where the latter are assumed to reflect the dissipation associated with topographic blocking and generated lee wave energy. It is shown that when applied to these Southern Ocean regions, the two closures differ most in their treatment of topographic blocking. For several reasons, pointwise validation of the closures is not possible using existing observations, but horizontally averaged comparisons between closure predictions and observations are made. When anisotropy of the underlying topography is accounted for, the two horizontally averaged closure predictions near the seafloor are approximately equal. The dissipation associated with topographic blocking is predicted by the Garner (2005) scheme to account for the majority of the depth‐integrated dissipation over the bottom 1000 m of the water column, where the horizontally averaged predictions lie well within the spatial variability of the horizontally averaged observations. Simplifications made by the Garner (2005) scheme that are inappropriate for the oceanic context, together with imperfect observational information, can partially account for the prediction‐observation disagreement, particularly in the upper water column.
Do East Australian Current anticyclonic eddies leave the Tasman Sea?
Authors: Pilo Gabriela S. , Oke Peter R. , Rykova Tatiana , Coleman Richard , Ridgway Ken 
Published: November 2015

AbstractUsing satellite altimetry and high‐resolution model output we analyze the pathway of large, long‐lived anticyclonic eddies that originate near the East Australian Current (EAC) separation point. We show that 25–30% of these eddies propagate southward, around Tasmania, leave the Tasman Sea, and decay in the Great Australian Bight. This pathway has not been previously documented owing to poor satellite sampling off eastern Tasmania. As eddies propagate southward, they often “stall” for several months at near‐constant latitude. Along the pathway eddies become increasingly barotropic. Eddy intensity is primarily influenced by merging with other eddies and a gradual decay otherwise. Surface temperature anomaly associated with anticyclonic eddies changes as they propagate, while surface salinity anomaly tends to remain relatively unchanged as they propagate.
