Published: July 2023

Abstract
Air stagnation refers to an extended period of clear, stable conditions which can favour the accumulation of pollutants in the lower atmosphere. In Europe, weather conditions are strongly mediated by the North Atlantic eddy-driven jet stream. Descriptions of the jet stream typically focus on its latitudinal position or the strength of its wind speed, and its impacts are often studied under different latitudinal regimes of the jet. Herein, we evaluate the influence of the jet stream on European air stagnation using a new multiparametric jet diagnostic that provides a more complete description of jet stream characteristics. We report large influences of the jet stream on regional stagnation and uncover links with jet structure that go beyond knowledge of its latitude. Accordingly, air stagnation anomalies show different, and often opposite, responses to jets in a given latitudinal position but with different additional characteristics. Statistical modelling reveals that the monthly variability in air stagnation explained by the new jet diagnostic is substantially higher compared to one that only considers the jet’s latitude and intensity. Knowledge of the average location of the jet in a given month, as described by a latitude or longitude parameter, together with the variability in the jet’s shape, appear key for the statistical models of air stagnation. The relationship between air stagnation and the jet stream is often nonlinear, particularly for regions in southern Europe. For northern regions it is generally more linear, but the additional jet parameters are essential for describing stagnation variability. These results have implications for studying air stagnation and its pollution impacts in seasonal forecasts and climate change projections.

Abstract
The NEMATENC-UFLA began studies on bamboo during the pandemic to disseminate the use of this millennial material in construction. For this purpose, a prototype was developed for the shelter of a hitchhiking point, located on the university campus. The planning was developed in several stages. Initially, live transmissions were organized with professionals and researchers of the bamboo species existing in the university. The projects were developed for the species Dendrocalamus asper and Bambusa tuldoides. After the cuts, the treatment adopted was immersion in a solution of borax, boric acid, and copper sulfate. The pieces were stored on pallet racks designed for this purpose. After the execution of the foundation, it was assembled on site. The entire executive process had the theoretical and practical training of MSc. CE Frederico Rosalino: reduced model; cutting of plug-in connections; use of the “Vellez System” in the pillar bases; and covering with a sandwich of esterillas and waterproofing blanket. Students, engineering professionals, and others, participated in the construction. The whole process had the support of PROINFRA and collaborators. The result reached the proposed goal: promote the aesthetics and physical-mechanical properties of bamboo, besides offering comfort to the users of the university campus.

Published: July 2023

Abstract
The acoustical pollution in conditions of urban territories is rapidly increasing and causing a negative impact to the population and to the staff of industrial enterprises. The sources of environmental noise generations are analyzed. Transport and industrial plants may be considered as the main noise sources in the city environment. New results of research of environmental noise in urban conditions before, during and after COVID-19 period on the Samara region of Russia are presented. Experimental results of noise measurements caused by traffic movement and industrial enterprises operation are discussed. Comparison of results of environmental noise measurements in urban conditions before and during COVID-19 period shows that transport noise level was reduced, but the industrial noise level was almost the same, especially in low frequency range. Approaches to reduction of increased environmental noise levels in urban conditions are suggested.

Abstract
Universities are regarded as reference institutions for the expansion of cultural and environmental activities. They are crucial to the advancement of sustainability as they advocate for a development pattern that would be compatible with ecological balance, biodiversity, and intergenerational fairness. In response to the rise in enrollment, CU has created a sustainable expansion plan for its campus. Because students will return to their communities and educate them about sustainability, universities are seen as the best places to apply the principle. Recently, Cairo University established a sustainability office as a governance framework to develop and implement sustainability action plans and to regularly measure and report overall progress towards its aim of a sustainable campus. This paper includes Cairo University’s efforts to transform the campus into a more sustainable society using UI GreenMetric categories. The present study shows the extent of Cairo University’s commitment to achieving the United Nations sustainable development goals, as well as Egypt’s Vision 2030. In all areas, including setting and infrastructures, energy, water and wastes, Cairo University supports the fundamental principles of sustainability and green development.

Abstract
The University of Florence (UniFi) started participating in the UI GreenMetric ranking in 2018 to measure its commitments toward sustainability. Since then, several actions have been adopted to make advancements in the six categories of the ranking, spanning from the high-quality classroom environment to actions for the well-being of students. UniFi considers sustainability a transversal discipline addressed by all the schools in its different aspects (e.g. well-being, building structure, energy efficiency, climate change responsibility, waste management, and saving water resources). In particular, the cutting edge of UniFi is represented by its education sector. The total number of courses regarding the 17 Sustainable Development Goals in 2020/21 is increasing, covering now 26% of the academic offerings. These offerings give our students many opportunities to grow with their awareness of the current difficulties, providing the instruments to address their future. This is possible also thanks to the cultural events that UniFi promotes every year, despite the difficulties raised by COVID-19. Moreover, an average of ~3700 scholarly papers related to sustainability has been published in each of the last three years, the outcome of the excellent work of the UniFi researchers. Thanks to start-ups, the academic expertise on sustainability has also been taken outside to the industrial sector.

Abstract
This article examines the impact of the large-scale Upper Cisokan Pumped Storage Hydropower (UCPSH) development project, in West Java, Indonesia on household livelihoods. The process of land acquisition and resettlement has taken away land-based resources that are the source of livelihood for households in 4 villages around the project. This article discusses how the resilience of household livelihoods occurs 5 years after land acquisition and resettlement. This study was conducted by interviewing 134 households affected by land acquisition and resettlement living in the vicinity of the UCPSH project site. The level of severity is studied to see how the household can respond to disturbances. Livelihood resilience in affected households occurs when the household’s livelihood system can absorb disturbances, then responds by re-establishing livelihood capital and assets. Livelihood strategies are carried out based on the capacity possessed to maintain and improve the quality of life. As a result, there are two livelihood strategies carried out by the affected households, the agricultural intensification strategy has improved 9% of living conditions and the livelihood diversification strategy has improved 2.5% of living conditions.

Published: July 2023

AbstractHuman activities in modifying land use and land cover increasingly put pressure to many regulatory ecosystem services, one of which is carbon sequestration. If forests, the area with the most vegetation cover are decrease, the amount of carbon sequestered will decrease significantly. Currently, agroforestry systems or Talun (in West Java) in Sumedang was eleven times larger than secondary forest. Carbon stocks in this agricultural area need to be estimated so that their carbon sequestration capacity can be known in order to improve the quality of regulatory ecosystem services. NDVI value of the Landsat 8 OLI was obtained by conducting raster calculation in ArcMap. Field inventory was conducted by measuring stem DBH and height of all vegetation stands in 31 plots measuring 30 x 30 m, a similar plot size to the resolution of the Landsat imagery. Biomass of vegetation stands was calculated using allometric equations and then converted into the carbon content of the biomass. In order to analyze the correlation of NDVI and carbon inventory data, a Pearson product-moment correlation analysis in the form of simple linear regression, non-linear exponential, and polynomial order 2 and order 3 model were carried out. Standard error of estimate (SEE) was performed to identify the best equation to model the aboveground carbon stocks in the area. The results show that the four regression models give a positive correlation between NDVI and carbon stocks. The strongest category was the polynomial order 2 and order 3 regression model with 0.795 coefficient of determination. Yet, the linear simple regression model obtained the highest accuracy with estimated error 0.445 tons/pixel. The estimated carbon stock obtained by linear regression model was 16150.40 tons with an average of 104.95 tons/ha. Visually, according to carbon distribution map, the carbon content of vegetation stands in the mixed garden of Rancakalong was mainly distributed in the north of Rancakalong District which is located in Cibungur Village.

Published: July 2023

Abstract
Gunung Leuser National Park (GLNP) priority species is a surrogate species representing four wildlife, Panthera tigris sumatrae, Dicerorhinus sumatrensis, Elephas maximus sumatrensis, and Pongo abelii living within GLNP. GLNP priority species was appointed based on the extinction status, endemicity, population and habitat conditions, threat, and regional representation of wildlife. “GLNP priority species” terminology was considered from flagship species, keystone species, umbrella species, or charismatic species. This literature review aimed to clarify the appropriateness of GLNP priority species to other surrogates by comparing the characters and distributions of GLNP priority species to the definition of surrogate species. This review identified five surrogate species: key-stone species, indicator species, umbrella species, flagship species, and charismatic species. GLNP priority species are appropriate to be GLNP flagship species based on two considerations: (1) the characters of all GLNP priority species which are endemic wildlife of Sumatera and are critically endangered based on the International Union for Conservation of Natures’ status and (2) the condition of the priority species distributions which periodically decreased (elephant and rhino) and are threatened (tiger and orangutan). Besides, tiger and orangutan also can be determined as umbrella species considering their distribution spreads which are extensively covering the GLNP area.

Abstract
The concept of a sustainable city that has been described in the Sustainable Development Goals (SDGs) requires all cities in the world to implement it to solve climate problems that if not handled are increasing every year. The impact of climate change, which is a global problem, can affect lives, such as hydrometeorological disasters especially floods. Flood problems can be overcome with the Blue Green Infrastructure (BGI) development approach, one of which is green open space with a retention pond as an effort to achieve the SDGs in the Sustainable City component. Based on this statement, this study will identify in determining the location of BGI development in this case green open space with retention ponds to support the concept of sustainable planning and resilience in one of the metropolitan cities in Indonesia, Jakarta, which is the most populous city that has high rainfall and has minimal open space. The construction of the BGI is carried out as an effort to reduce the impact of climate change in the form of flooding by structural mitigation in the conservation of water balance in urban development, improving water quality, and reducing rainwater runoff and peak flows. This research was carried out in stages in the form of identification of urban land cover changes with image crawling as justification for the massive addition of built-up land, identification of vegetation density and temperature with Land Surface Temperature (LST) and flood hazard, with identification of retention pond needs. Eventually, recommendations for BGI development locations were given based on changes in urban land, temperature, vegetation, and flood hazard as well as the fulfilment of supporting infrastructure needs.

Abstract
The prevalence of catastrophic structural member failure caused by steel corrosion in civil infrastructure underscores the importance of reducing reinforcement corrosion to enhance overall infrastructure costs, reliability, and sustainable development. The present research investigates the potential of corrosion inhibitors to enhance the durability and strength of concrete structures, with a focus on their long-term effectiveness in resisting corrosion in reinforced concrete structures. Multiple approaches such as inhibitors, repairing processes, and coatings have been explored to prevent concrete corrosion damage, with an emphasis on concrete corrosion performance in coastal and corrosive situations. This study investigates the effect of six different corrosion inhibitors (zinc oxide, magnesium oxide, urea, sodium nitrate, sodium molybdate, and diethyl ether) on the compressive strength and durability of concrete samples. The compressive strength is assessed using both destructive (28 days cube compressive strength) and non-destructive (Ultrasonic Pulse Velocity) test methods, while concrete durability is evaluated using the rapid chloride permeability test (RCPT). The compressive strength of the admixture incorporated samples are found to be higher than the control sample by almost 50% and above with excellent concrete quality. The RCPT values of inhibitor-incorporated samples are moderate and low with control samples having high permeability even in adverse conditions of freezing, thawing, and deicing. The samples incorporated with inhibitors also show less negative half-cell potential which is 1.43 times less than that of the control sample indicating the lesser probability of occurrence of corrosion. SEM imaging is also conducted to analyze the microstructure of each mix. The findings of this study highlight the importance of inhibitors in enhancing the durability of reinforced concrete structures.

Published: July 2023

Abstract

Background
Guidelines suggest that the serum carbohydrate antigen (CA19-9) level should be used when deciding on neoadjuvant treatment in patients with resectable and borderline resectable pancreatic ductal adenocarcinoma (hereafter referred to as pancreatic cancer). In patients with resectable pancreatic cancer, neoadjuvant therapy is advised when the CA19-9 level is ‘markedly elevated’. This study investigated the impact of baseline CA19-9 concentration on the treatment effect of neoadjuvant chemoradiotherapy (CRT) in patients with resectable and borderline resectable pancreatic cancers.

Methods
In this post hoc analysis, data were obtained from two RCTs that compared neoadjuvant CRT with upfront surgery in patients with resectable and borderline resectable pancreatic cancers. The effect of neoadjuvant treatment on overall survival was compared between patients with a serum CA19-9 level above or below 500 units/ml using the interaction test.

Results
Of 296 patients, 179 were eligible for analysis, 90 in the neoadjuvant CRT group and 89 in the upfront surgery group. Neoadjuvant CRT was associated with superior overall survival (HR 0.67, 95 per cent c.i. 0.48 to 0.94; P = 0.019). Among 127 patients (70, 9 per cent) with a low CA19-9 level, median overall survival was 23.5 months with neoadjuvant CRT and 16.3 months with upfront surgery (HR 0.63, 0.42 to 0.93). For 52 patients (29 per cent) with a high CA19-9 level, median overall survival was 15.5 months with neoadjuvant CRT and 12.9 months with upfront surgery (HR 0.82, 0.45 to 1.49). The interaction test for CA19-9 level exceeding 500 units/ml on the treatment effect of neoadjuvant CRT was not significant (P = 0.501).

Conclusion
Baseline serum CA19-9 level defined as either high or low has prognostic value, but was not associated with the treatment effect of neoadjuvant CRT in patients with resectable and borderline resectable pancreatic cancers, in contrast with current guideline advice.

Abstract

Background
Previous studies have reported conflicting results of prolonged antibiotic prophylaxis on infectious complications after pancreatoduodenectomy. This study evaluated the effect of prolonged antibiotics on surgical-site infections (SSIs) after pancreatoduodenectomy.

Methods
A systematic review and meta-analysis was undertaken of SSIs in patients with perioperative (within 24 h) versus prolonged antibiotic (over 24 h) prophylaxis after pancreatoduodenectomy. SSIs were classified as organ/space infections or superficial SSI within 30 days after surgery. ORs were calculated using a Mantel–Haenszel fixed-effect model.

Results
Ten studies were included in the qualitative analysis, of which 8 reporting on 1170 patients were included in the quantitative analysis. The duration of prolonged antibiotic prophylaxis varied between 2 and 10 days after surgery. Four studies reporting on 782 patients showed comparable organ/space infection rates in patients receiving perioperative and prolonged antibiotics (OR 1.35, 95 per cent c.i. 0.94 to 1.93). However, among patients with preoperative biliary drainage (5 studies reporting on 577 patients), organ/space infection rates were lower with prolonged compared with perioperative antibiotics (OR 2.09, 1.43 to 3.07). Three studies (633 patients) demonstrated comparable superficial SSI rates between patients receiving perioperative versus prolonged prophylaxis (OR 1.54, 0.97 to 2.44), as well as in patients with preoperative biliary drainage in 4 studies reporting on 431 patients (OR 1.60, 0.89 to 2.88).

Conclusion
Prolonged antibiotic prophylaxis is associated with fewer organ/space infection in patients who undergo preoperative biliary drainage. However, the optimal duration of antibiotic prophylaxis after pancreatoduodenectomy remains to be determined and warrants confirmation in an RCT.
