Cultivating communities in Mendoza, Argentina: Exploring social aspects of urban agriculture
Authors: Mietz Lena K. , Civit Bárbara M. , Arena Alejandro P. 
Published: December 2023

Abstract
Global food production and security are current challenges. This is reflected, among other things, in the fact that more than 690 million people suffer from hunger or food shortages. The availability of nutritious food is critical for disease control and immune function. In this context, urban agriculture is promoted as a way to ensure access to food, which has developed due to rising prices, food shortages and urban growth. However, there is a lack of in-depth knowledge on the impacts as well as barriers to implementation. Therefore, this study investigates vegetable consumption patterns in the metropolitan city of Mendoza in Argentina, as well as interest in vegetable production, opinions on urban agriculture and barriers. Quantitative research methods were used, and a citizen survey was conducted. The data was analysed using SPSS software and correlations were determined using chi-square. The results show strong interest from citizen in urban agriculture, but also barriers such as lack of time and resources. Successful implementation requires initiative, political will, and acceptance. The results are consistent with other studies and could be further explored in longitudinal studies to assess effectiveness. This is helpful given the importance of urban agriculture and vegetable consumption for sustainable food production and supply.

Published: December 2023

Abstract
This study evaluates the effects of lycopene administration on body weight, mortality, cloacal temperature, and haematological responses, in broiler chickens exposed to heat stress. 40 day-old broiler chicks were divided into control and lycopene groups, 20 chickens each. Each bird in the control group received olive oil (1 ml.kg−1), and lycopene at 10 mg.kg−1 mixed with olive oil was given to each bird in the lycopene group by oral gavage once daily for 28 days. The dry- and wet-bulb temperature of the broiler chickens’ pen was recorded three times daily from days 8 to 28. The body weights were measured weekly. The incidence of mortality was recorded. The cloacal temperatures were measured on days 14, 21 and 28. The blood samples were collected for haematological analyses, on day 28. The results indicated a high overall temperature-humidity index (31.24 ± 0.43 oC) of the thermal micro-environment of the broiler chickens. There was no significant difference (P > 0.05) in body weight. The percentage mortality in the control group was relatively higher compared to the lycopene group. Lycopene reduced the cloacal temperature responses and the daily fluctuations in broiler chickens. The decreased (P < 0.05) heterophil:lymphocyte ratio and percentage erythrocytes haemolysis were recorded in the lycopene group. In conclusion, lycopene administration reduced mortality and improved cloacal temperature and haematological responses without exerting any significant beneficial or negative effects on the body weight in broiler chickens exposed to heat stress.
Der digitale Euro: Chancen und Risiken einer digitalen Notenbankwährung
Authors: Broemel Roland , Meyer-Gohde Alexander , Wieland Volker 
Published: December 2023

Abstract
Central banks including the ECB have moved forward with plans concerning a central bank digital currency (CBDC) to be made available to the public at large. In particular, the announcement of a private stable coin by a consortium led by Facebook/Meta had served as a catalyst. Perhaps the fear of losing market share in terms of seigniorage or impairment of monetary policy played a role. By now, however, a widely-expressed criticism is that the CBDC constitutes a solution that is still in search of a problem to be solved. The argument put forth by the ECB that a CBDC is needed as a monetary anchor in the digital sphere carries little weight after closer inspection. Furthermore, potential advantages of a CBDC are partly reduced or precluded because of constraints imposed in order to minimise potential risks for the stability of the banking system and the business model of banks. For example, the model pursued by the ECB refrains from positive or negative interest rates paid on CBDC, imposes limits on transaction amounts and precludes a store of value function. At this point, the main potential benefit appears to be a possible reduction of transaction costs in digital payments and a possible contribution to keeping platform-based markets in digital ecosystems contestable. It remains an open question whether this is a task for central banks.
Der digitale Euro aus einer historischen Perspektive
Authors: Greitens Jan 
Published: December 2023

Abstract
The introduction of a digital currency is part of the continuous evolution of the financial system, which has always been driven by technological innovations. For the first time in many years, Western central banks are exposed to potential currency competition. But a digital euro also has the potential to affect the two-tier structure of the grown financial system. The ECB should not engage in an interest rate competition with commercial banks and the digital currency should remain non-interest-bearing. Instead of imposing holding limits, notice periods could also be used to reduce the risk of bank runs. The ECB should limit itself and implement a hybrid digital central bank currency.

Politökonomische Reaktivierung des Ruhrgebiets durch neue staatliche Institutionen
Authors: van de Loo Kai , Hanske Julia 
Published: December 2023

Abstract
The Ruhr area is not only the former heartland of industry in Germany, but still the largest urban agglomeration and now the region with the highest density of universities. Yet, after decades of deep structural change leading away from coal and steel, the region is still marked by ongoing structural weaknesses and chronically high unemployment rates. At the same time, it has relatively poor public institutions. Therefore, it is time to think outside the box. We propose a new approach with ten concrete ideas for regional support by the establishment of new public institutions in the Ruhr area.

ЭКСПЕРИМЕНТАЛЬНОЕ ИССЛЕДОВАНИЕ НАДМОЛЕКУЛЯРНОЙ СТРУКТУРЫ СЫВОРОТОЧНОГО АЛЬБУМИНА
Authors: Волкова А. В. , Бузоверя М. Э. 
Published: December 2023

В работе представлены результаты экспериментальных исследований водно-солевых растворов сывороточного альбумина человека (САЧ), который рассматривается как аналог биожидкостей организма. Наблюдаемые структурные эффекты в дегидратированных пленках рассмотрены с учетом концепции надмолекулярной организации полимерного тела и его многоуровневой структуры. Для изучения образцов была разработана и опробована единая комплексная методика, включающая в себя исследования надмолекулярной структуры (НМС) всей капли на оптическом уровне (микроуровень) и морфологии глобулярных структурных элементов альбуминовой пленки (наноуровень) методом атомно-силовой микроскопии (АСМ). Обработка фаций САЧ с помощью программно-аппаратного комплекса «Морфо» позволила установить зависимости НМС фации от концентрации альбумина. На оптическом уровне удалось наблюдать сложно-ступенчатый механизм изменения надмолекулярной структуры водно-солевых фаций альбумина. Исследование показало, что с повышением концентрации белка площадь области кристаллизации дендритов падает. При концентрации 10 % САЧ происходит структурный переход: дендритно-фрактальная морфология сменяется системой трещин и отдельных конкреций. Методом атомно-силовой микроскопии была выявлена глобулярная структура белковой матрицы. Проведена оценка размеров единичной глобулы и белковых ассоциатов, и плотности их упаковки в зависимости от концентрации.

Published: December 2023

Nesse estudo foram utilizados dados de precipitação, temperatura máxima e mínima obtidos através da Agência Nacional das águas (ANA) para o período de 1961-2010 e através do INMET. Todas as séries foram submetidas ao teste de Mann-Kendall para identificar tendências e depois os valores das tendências serão submetidas ao teste de T-Student para verificar se os valores de tendência encontrados são significativos estatisticamente ou não. O norte do estado de Alagoas apresentou tendência de diminuir as precipitações e aumentar as temperaturas máximas. Com essas conclusões, políticas públicas devem ser adotadas, pois a região ficará mais quente e com menos chuvas, o que pode levar a conflitos devido disponibilidade hídrica, ao déficit hídrico, à fuga da população local, à diminuição de atividades agropecuárias etc. A B S T R A C T In this study were used data of precipitation, maximum and minimum temperature obtained through the National Water Agency (ANA) for the period 1961-2010 and by INMET. All series were subjected to the Mann-Kendall test for trends and then the values ​​of the trends will be submitted to the Student's t-test to see if the trend values ​​found are statistically significant or not. The northern state of Alagoas tended to decrease precipitation and increase the maximum temperatures. With these findings, public policy should be adopted, since the region will be warmer and less rainfall, which can lead to conflicts because of water availability, water deficit, the escape of the local population, the decrease of agricultural activities etc. Keywords: Mann-Kendall test, T-Student student, Climate variations, Semi-arid

O Estado de Alagoas é um dos maiores produtores de cana-de-açúcar no Brasil e faz uso da prática das queimadas para auxiliar na colheita da cana-de-açúcar. O módulo químico do modelo atmosférico WRF (WRF/CHEM – Weather Reaserch Forecasting/CHEMistry), possibilitou as análises de concentração e dispersão do gás traço Monóxido de Carbono (CO), oriundo dos focos de queimadas detectadas pelo satélite AQUA (sensor MODIS), do dia 01 a 06 de novembro/2011. Para avaliar a dispersão foi utilizada a direção e a velocidade do vento a 10 metros de altura, no sentido de estimar o destino da pluma de gás emitida pela queimada. Verificou-se que o CO pode afetar a qualidade do ar local ao assumir altas concentrações a poucos quilômetros da fonte de emissão (cerca de 3000 ppbv), porém com a dispersão do gás em função do vento, é possível ver concentrações próximas a 800 ppbv, pelo menos a 100 km da fonte de emissão. A B S T R A C T The state of Alagoas is one of the largest producers of sugar cane in Brazil and makes use of the practice of burning to help harvest sugar cane. The chemical module of the atmospheric model WRF (WRF/CHEM - Research Weather Forecasting/Chemistry), allowed the analysis of the concentration and dispersion of trace gas carbon monoxide (CO), arising from burning source detected operationally at the National Institute for Space Research (INPE), for the MODIS (Moderate Resolution Imaging Spectroradiometer) sensor present in the National Aeronautics and Space Administration (NASA) AQUA satellite, between days 1 to November 6, 2011. For dispersion evaluation, it was used wind direction and speed at 10 meters high, in order to estimate the destination of the gas plume emitted by the sugar cane burn. It was seen that the CO can affect local air quality by taking high concentrations within a few miles of the emission source (about 3000 ppbv). However, with the gas dispersion promoted by the wind, it is possible to see concentrations about 800 ppbv at least 100 km from the emission source.

Brenan; Poincianella pyramidalis Tul.; Piptadenia stipulacea (Benth) Ducke; Erythrina velutina Willd.; e, Enterolobium contortisiliquum (Vell.) Morong. Assim, foi conduzido um experimento em viveiro, no município de Serra Talhada-PE. As sementes foram submetidas a tratamentos pré-germinativos. Cada espécie constituiu um tratamento, dispostas em delineamento inteiramente casualizado. A reposição de água foi feita com base na evapotranspiração prevista para o período experimental. Aos 23, 37, 51, 65, 92 e 120 dias após a semeadura foram feitas amostragens para se determinar a biomassa seca das plantas, bem como de suas partes, folhas, caule e raízes e parâmetros biométricos. Com os valores de biomassa seca e índice de área foliar foram determinados os seguintes índices morfofisiológicos: taxa de crescimento absoluto, taxa de crescimento relativo, área foliar específica, razão de área foliar, razão de massa foliar. Tamboril e Algaroba foram aquelas que apresentaram melhores respostas biométricas e de acúmulo de biomassa, em decorrência dos seus desempenhos morfofisiológicos. Por sua vez, Angico Vermelho apresentou o menor crescimento inicial quando comparado com as demais espécies.
