A qualidade microbiológica da água associada à saúde pública é essencial na aplicação de conhecimentos epidemiológicos para se adotar medidas preventivas de saneamento. O objetivo desse estudo foi avaliar as concentrações de Escherichia coli nas águas superficiais da Bacia Hidrográfica dos Rios Turvo e Grande e suas implicações na saúde pública. A área de estudo compreende a Bacia Hidrográfica dos Rios Turvo e Grande localizada na região Noroeste do Estado de São Paulo. Foram avaliados 21 pontos de monitoramento e coletados dados brutos das análises microbiológicas da água obtidos por meio da Rede Básica integrada da ANA/CETESB, referente ao monitoramento de 2019. Os dados foram comparados com os padrões de qualidade de água estabelecidos pela legislação do Estado de São Paulo e Brasileira. A estimação da proporção de amostras nos padrões qualidade de água foi por intervalo com 95% de confiança. Constatou-se que apenas 51,2% ± 8,8% das amostras de água da Bacia Hidrográfica estavam de acordo com o limite estabelecido nas legislações para águas doce de classe 2. Evidencia-se uma deficiência da qualidade microbiológica da água, visto que as concentrações de E. coli estão acima do limite estabelecido nas duas legislações em 48,8% ± 8,8% das amostras oferecendo riscos à saúde da população exposta e ao meio ambiente. Assim, destaca-se a importância do monitoramento da qualidade da água e de maiores investimentos sociopolíticos para efetivação das medidas de saneamento básico, a fim de verificar a qualidade das bacias hidrográficas e limitar possíveis surtos de doenças de veiculação hídrica.

Published: June 2023

Os rios são parte da identidade da cidade de Petrópolis, localizada entre vales e recortada por rios. A sua implantação na Serra da Estrela parte do conjunto da Serra do Mar, no estado do Rio de Janeiro, Brasil, e atendeu ao modelo de urbanização proposto pelo Major Frederico Köeler, um projeto que determina a implantação da cidade tirando partido da presença dos rios, que receberam calçadas arborizadas, cujas dimensões variavam de acordo com a proximidade do Palácio Imperial. Em contrapartida, a região possui desafios para lidar com o crescimento urbano e sua relação com os cursos de água e relevo da cidade. A região do Caxambu está inserida ao lado do Centro Histórico e se estende até o Parque Nacional da Serra dos Órgãos – o PARNASO. Essa característica e extensão trazem a divisão em três sub-regiões relacionadas com as bordas ou fronteiras. Sendo assim, o Quarteirão Suíço, o Caxambu Luzitano e o Santa Isabel, mesmo sendo parte do Caxambu, possuem importantes particularidades tanto em sua ocupação quanto na dinâmica de sua expansão. O bairro não foi fruto de um planejamento urbano, e, com isso, sua relação com o rio diverge da área central de Petrópolis, marcada pela relação de apreciação dos cursos de água. O objetivo do trabalho foi evidenciar a formação social e histórica do Caxambu e sua ligação com os cursos de água, bem como evidenciar como as recentes chuvas transformaram a paisagem urbana do bairro. Foram feitas pesquisas históricas, iconográficas e entrevistas com moradores.

Municipal Plan for Integrated Solid Waste Management (MPI-SWM) in the state of Piauí: A portrait of Coastal Cities
Authors: Carvalho Helder Araujo de , Lopes João Batista , Carvalho José Natanael Fontenele de 
Published: June 2023

The PMGIRS is an important instrument of the National Solid Waste Policy (PNRS) that articulates the management of municipal waste with the state plan and the latter, in turn, dialogues with the national plan. It is through the evaluation of the PMGIRS that the municipal manager detects whether the plan meets the requirements of the PNRS and which local actions (municipal scope) have been successful towards the goals of the municipal plan. The objective was to evaluate the PMGIRS of the coastal cities of Piauí, according to what the PNRS prescribes. To meet the objective, we used the instrument for this purpose, which is composed of twenty-one indicators and four indices. The indicators of the municipalities were mostly evaluated as bad and with rates below the recommended by the literature. In general, the instrument's indicators point to the difficulty of municipalities in complying with what the PNRS recommends. The study brings theoretical and managerial contributions. In the theoretical field, it broadens the understanding of the situation of coastal municipalities, part of the tourist route made up of three states, belonging to an environmental protection area, located in the northeast of Brazil, in relation to the local management of their waste. In the managerial field, the findings serve as a subsidy for the PMGIRS review and as an indicator, at the state level, for the formulation of actions that mobilize managers to prepare the local plan and/or encourage them to create intermunicipal consortia with a focus on the destination adequate waste.

Authors: Darwin Darwin 
Published: June 2023

Abstract. This research aimed to analyze the influence of rheological properties of ketchup on the pump power, required during transporting process. This research was done through using a computer programme designed for calculating and analyzing the influence of rheological properties toward materials and equipments installed in the transport system. Those rheological properties derived from laboratory analysis and literature review include viscosity and density from any type of ketchup. Results analysed by a computer programming revealed that flow behaviour Index (n) and consistency coefficient (m) were the rheological properties interacting with each other since these parameters were the viscosity of ketchup that influences energy losses in the transport system. Once the total of energy losses was obtained from the system, the pump power required for transfering the product also can be known. Based on the simulation conducted by using rheological parameters of ketchup with consistency coefficient of 12.33 PaSn, and flow behaviour Index at 0.41 was obtained total energy losses at 202.26 J/kg with the pump power requirement at 0.22 kW. Once consistency coefficient was 18.7 PaSn, and flow behaviour Index was at around 0.4, the total of energy losses increased to 277.58 J/kg with pump power requirement at 0.28 kW. Abstrak. Penelitian ini bertujuan untuk menganalisa pengaruh dari sifa-sifat reologi dari kecap terhadap daya pompa yang dibutuhkan selama proses transfer atau pengalirannya. Penelitian ini dilakukan menggunakan suatu program komputer yang didesain untuk menghitung dan menganalisa pengaruh sifat-sifat reologi terhadap peralatan dan bahan yang digunakan pada sistem transfer. Sifat-sifat reologi tersebut diperoleh dari analisis laboratorium dan studi literatur yang berupa viskositas dan densitas dari berbagai tipe kecap. Hasil yang telah dianalisis dengan program komputer mengungkapkan bahwa index perilaku aliran (n) dan koefisien konsistensi (m) merupakan sifat reologi bahan yang saling berinteraksi, hal ini karena parameter tersebut merupakan viskositas dari kecap yang mempengaruhi kehilangan energi pada sistem transfer. Ketika total kehilangan energi dari sistem diketahui, maka daya pompa yang dibutuhkan untuk mentransferkan produk kecap tersebut juga dapat diketahui. Berdasarkan simulasi yang dilakukan dengan menggunakan parameter-parameter reologi dari kecap dengan koefisien konsistensi 12.33 PaSndan index perilaku aliran 0.41 maka diperoleh total kehilangan energi sebesar 202.26 J/kg, daya pompa yang dibutuhkan sebesar 0.22 kW. Ketika koefisien konsistensi bahan 18.7 PaSn, dan index perilaku aliran 0.4, maka total kehilangan energi meningkat menjadi 277.58 J/kg dengan daya pompa yang dibutuhkan juga meningkat menjadi 0.28 kW.

Abstrak. Lengkuas (Alpinia galanga) adalah salah satu tanaman penting bagi masyarakat Indonesia. Tanaman ini dapat digunakan untuk bumbu masakan dan obat herbal. Tujuan kajian ini adalah untuk menduga umur simpan lengkuas segar dengan menggunakan model Arrhenius. Lengkuas segar yang baru dipanen dibersihkan dan dipotong-potong dengan ukuran 2cm, kemudian disimpan pada suhu 5, 10 dan 28°C. Evaluasi dilakukan oleh 25 orang panelis dengan menggunakan skala hedonic dari sangat suka sampai sangat tidak suka terhadap warna, kesegaran, aroma dan tekstur. Parameter yang diamati adalah kadar air dan kadar sari larut dalam air. Parameter tersebut diamati dalam interval 3 hari selama 21 hari atau sampai sampel dinyatakan tidak disukai oleh panelis pada salah satu kriteria hedoniknya. Hasil penelitian menunjukkan bahwa pad asuhu 28°C, lengkuas dapat disimpan selama 3 hari, sedangkan pada suhu 10 dan 5°C, lengkuas dapat disimpan selama 12 dan 21 hari. Energi aktivasi (EA) dan tingkat perubahan mutu (Q10) karena kadar sari larut dalam air lebih besar dari energi aktivasi (EA) dan tingkat perubahan mutu (Q10) karena kadar air lengkuas. Namun demikian, kedua parameter tersebut tidak tepat digunakan untuk menduga umur simpan lengkuas. Shelf-Life Prediction of Galanga by Using Arrhenius Model Based on Its Moisture and Water Soluble Extract Content Abstract. Galanga (Alpinia galanga) is one of important plants for Indonesian people. It can be used as spices and also as herbal medicine. The aim of this study is to predict the shelf-life of fresh galanga by using Arrhenius model. Fresh harvested galanga, which was cleaned and chopped at width about 2 cm, was stored at temperatures 5, 10, and 28°C. The evaluation was done by 25 respondents by using hedonic scale from the range of like very much until dislike very much. This hedonic evaluation was assessed, based on colour, freshness, aroma, and texture. Parameters observed were moisture and water soluble extract content. These parameters observed at interval 3 days for 21 days or until the samples were rejected by respondents for at least one of hedonic factors. Results showed that at temperature 28°C, galangal can be stored for 3 days. However, at temperature 10 and 5 °C, galangal can be stored for 12 and 21 days, respectively. The energy act ivation (EA) and the rate of quality change (Q10) due to water soluble extract were higher than those of water content. Nevertheless, these two parameters cannot be used in prediction the shelf-life of fresh galanga.

Published: June 2023

Background: The transmission of SARS-CoV-2 from mother to fetus and the development of protective antibodies in newborns are critical aspects of maternal and neonatal care during the COVID-19 pandemic. Understanding the association between umbilical cord IgG COVID-19 antibody levels and maternal factors, including gestational age of acquiring infection, COVID-19 clinical category, and immunization status, can provide insights into neonatal immunity and guide strategies for optimizing maternal and neonatal care.
Methods: This study aimed to investigate the association between umbilical cord IgG COVID-19 antibody levels and maternal factors in a cohort of pregnant women with confirmed SARS-CoV-2 infection. Maternal data, including gestational age of acquiring infection, COVID-19 clinical category, and immunization status, were collected. Umbilical cord blood samples were obtained at delivery, and IgG COVID-19 antibody levels were measured using standardized assays. Statistical analyses were performed to assess the associations between maternal factors and neonatal antibody levels.
Results: Preliminary results showed that gestational age of acquiring infection was positively associated with umbilical cord IgG COVID-19 antibody levels (p<0.001). Neonates born to mothers infected in the third trimester had significantly higher antibody levels compared to those infected in the first or second trimesters. Additionally, there was a significant positive correlation between COVID-19 clinical category and umbilical cord IgG antibody levels, with more severe maternal illness associated with higher neonatal antibody levels. Maternal immunization status also demonstrated a positive association with umbilical cord IgG COVID-19 antibody levels, indicating that vaccinated mothers had higher levels of antibodies transferred to their infants.
Conclusion: This study highlights the association between umbilical cord IgG COVID-19 antibody levels and maternal factors, including gestational age of acquiring infection, COVID-19 clinical category, and immunization status. The findings suggest that infection in the third trimester, more severe maternal illness, and maternal immunization are associated with higher levels of neonatal antibodies. These results have important implications for understanding neonatal immunity and guiding maternal and neonatal care during the COVID-19 pandemic. Further research with larger cohorts is warranted to validate these findings and inform evidence-based strategies for optimizing maternal and neonatal outcomes.

Relevance. Potato is one of the most important agricultural crops used for various purposes. Its tubers are an essential food product for many people worldwide. The development of breeding technologies and an accelerated marketing of new promising potato genotypes play a significant role in the industry of potato production today. FSBSI “FSC of Agricultural Biotechnologies of the Far East named after A.K. Chaiki” conducted a complex study on potato hybrids.The research goal was to evaluate and select promising potato hybrids with high yield, marketability, and resistance to the most dangerous diseases. The experiments were carried out in our breeding nurseries located at Putsilovka v., Ussuriysk district, in the Kazachka river valley. Hybrids Purple potato × Manifest and (Aspiya×Qusto) × Manifest were used as the research object. The methodology of FSBSI “N. I. Vavilov All-Russian Institute of Plant Genetic Resources” and FSBSI “Russian Potato Research Center” were employed for the trials of the material. Fifty-two potato varieties from different maturity groups were used as pollen sources.Results. As the result, seventy-one hybrid combinations were created, 2272 flowers were pollinated, and 640 potato fruits were obtained. The efficiency of the crossing was 28.2%. Hybrids Pri15-12-23 Purple potato × Manifest and Pri-15-15-7 (Aspiya×Qusto) × Manifest had the highest rate of potato fruit formation. These accessions were characterized by good taste and high yield (48.7-51.0 t/ha), starch content (13.9-16.3 %), and vitamin C (15.0-15.4 mg/100 g). Tubers of these genotypes were oblong-oval or round with yellow flesh and small eyes. The studied accessions showed resistance to the main plant pathogens of the Russian Far East. Currently the obtained genotypes are tested for resistance to potato wart disease (S. Endobioticum, Dahlem pathotype) in the State variety trials. These accessions generate significant interest for breeding.
