Quality Evaluation of Pickled Ivy Gourd (Coccinia grandis) | Chapter 11 | Current Research in Agriculture and Horticulture Vol. 1

Ivy gourd is an underutilized vegetables found in the North of Minas Gerais State-Brazil. It is mainly consumed raw as salad. Pickling fruits can enhance the commercial exploitation of this species. However, no information on the processing techniques of the ivy gourd fruits in Brazil is found in literature. The objective of this study was to evaluate the quality parameters in the production of pickled ivy gourd. The treatments consisted of three bleaching times (3, 6 and 9 minutes), using a completely randomized design, with seven replicates. We evaluated the traits: instrumental analyzes of pH, color, total titratable acidity, soluble solids, texture and sensorial affective tests. The pH is within the indicated range (below 4.5) and the bleaching time influenced the color and texture alteration since the sample under 3-minute bleaching presented a greater tendency for green and greater firmness. For the sensory analysis, no significant difference related to sensory scoring was noticed; in relation to mode value, we concluded that the 6-minute sample was more preferable, though. For titratable total acidity and soluble solids analyses, no significant differences between the samples was noticed, considering that both parameters were within the standard when compared to other literature. We concluded that heat treatment influenced only the texture and color intensity and the preserved product showed good acceptability. Influência do tratamento térmico na qualidade de maxixinho (Coccinia grandis) em conserva O maxixinho é uma das hortaliças não convencionais encon-tradas no Norte de Minas Gerais, sendo consumido principalmente como salada crua. Uma forma de consumo que pode potencializar a exploração comercial desta espécie é a conserva. Entretanto, não existe informação sobre o processamento do maxixinho na forma de conserva no Brasil. Assim, o objetivo do presente trabalho foi elaborar picles de maxixinho e avaliar parâmetros de qualidade na produção de maxixinho em conserva. O experimento constou de três tratamentos, sendo eles a variação do tempo de branqueamento (3, 6 e 9 minutos). Foi empregado o delineamento inteiramente casualizado, com sete repetições. Foram avaliadas as características: análises instrumentais de pH, cor, acidez total titulável, sólidos solúveis, textura e testes sen-soriais afetivos. Observou se que o pH está dentro do indicado (abaixo de 4,5) e que o tempo de branqueamento influenciou na alteração da cor e da textura pois a amostra conduzida sob branqueamento de 3 minutos apresentou maior tendência ao verde e maior firmeza. Para a análise sensorial, não houve diferença significativa das notas, mas em função do valor da moda conclui-se que a amostra de 6 minutos teve maior preferência. Para as análises de acidez total titulável e sólidos solúveis, não houve diferença significativa entre as amostras, sendo que ambos os parâmetros se apresentaram dentro do padrão quando comparados com outras literaturas. Pode-se concluir que o tratamento térmico influenciou apenas na textura e na intensidade da cor e a conserva apresentou boa aceitabilidade.

Greening Regional Airports: A Vision for Carbon Neutral Infrastructure | Chapter 12 | Contemporary Perspective on Science, Technology and Research Vol. 3

 This study provides an overview of the energy demand of a regional airport, divided into individual time horizons. The electrification of aircraft systems raises the question of whether airports will be among the largest electricity consumers in our infrastructure in the future. Sustainability and especially emission reductions are significant challenges for airports that are currently being addressed. The Clean Sky 2 project GENESIS addresses the environmental sustainability of hybrid-electric 50-passenger aircraft systems in a life cycle perspective to support the development of a technology roadmap for the transition to sustainable and competitive electric aircraft systems. This article originates from the GENESIS research and describes various options for ground power supply at a regional airport. Potential solutions for airport infrastructure with a short (2030), medium (2040), and long (2050) time horizon are proposed. In addition to the environmental and conservation benefi...

There is No Standard Model of ZFC and ZFC2 | Chapter 03 | Advances in Mathematics and Computer Science Vol. 1

In this Chapter we obtain a contradictions in formal set theories under assumption that these theories have omega-models or nonstandard model with standard part. An possible generalization of Lob’s theorem is considered. Main results are: (i) ¬Con(ZF C+ ∃ M ZFC st ), (ii) ¬Con(N F+ ∃ M NF st ), (iii) ¬Con(ZF C 2 ), (iv) let k be an inaccessible cardinal then ¬Con(ZF C+ ∃ κ), (v) ¬Con(ZF C+ (V=L)), (vi) ¬Con(ZF+ (V=L)).

Occipital Dermal Sinus Tract Causing Craniospinal Infection: A Review | Chapter 13 | New Visions in Medicine and Medical Science Vol. 4

  Dermal sinus is a rare congenital condition characterized by a pathological tract connecting the skin to deeper tissues of the central nervous system, potentially leading to severe infectious complications. It arises from a failure in the separation of ectodermal layers during early gestation. Diagnosing dermal sinus tract in newborns requires a careful physical examination, focusing on midline dimples in the occipital region associated with cutaneous abnormalities like hairy nevus or hyperpigmentation. The presence of drainage, abnormal hair distribution, or localized swelling may indicate a sinus tract. Regular examination for dimples or sinuses is recommended for infants and children with recurrent meningitis or infections. Early detection is crucial to prevent severe complications like meningitis, with Staphylococcus aureus being a common causative organism. Neuroradiological studies, including computed tomography (CT) scan and magnetic resonance imaging (MRI), with histopath...
