This study represented the first comprehensive comparative analysis of chicken manure (CM) from mechanized European farms and traditional Cuban farms, revealing crucial regional differences in their characteristics for energy purposes. The aims this are: (i) to compare physical-chemical properties CM generated with extraction residues farms; (ii) assess quality these as raw material hydrothermal carbonization. According findings, exhibited higher levels biodegradation than those farms. High...
Bots, ou robôs digitais, são ferramentas úteis, cada vez mais presentes no ambiente acadêmico, auxiliando discentes e docentes com serviços esclarecimentos. No Centro de Ciências Agrárias da UFPB, em Areia, foi criado o “PET Descomplica”, uma parceria entre PET AgroBio Laboratório Entomologia, objetivo orientar sobre essenciais do campus. O chatbot superou as expectativas, oferecendo respostas rápidas recebendo média 4 (escala Likert 1-5). Avaliações indicaram 41% como ótimo, 33,33% bom,...
Este estudo teve como objetivo analisar os desafios e as perspectivas da avaliação revisão curricular na prática educacional. O problema de pesquisa abordou dificuldades enfrentadas pelos gestores professores implementação práticas avaliativas eficazes adaptação do currículo às necessidades sociedade contemporânea. A seguiu uma metodologia bibliográfica, com análise documentos, livros artigos científicos relacionados à curricular, demandas educacionais atuais. Os resultados revelaram que,...
The present Cuban economic model focuses on renewable sources of energy production, according to sustainable development strategies for 2030. However, the do not consider biogas (or methane) due to, among other reasons, a lack knowledge its actual potential. Following methodology batch anaerobic digestion process, study shows biomethane potential contained in most critical agricultural solid wastesgenerated Cuba, i.e., rice straw, cane corn bean banana straw (leaves), coffee husk, and...
Abstract BACKGROUND Microbial community dynamics during the anaerobic digestion of vinasse has been little studied. However, having knowledge about it is essential for early detection reactor operational difficulties to apply preventive actions. This research studies microbial in vinasse, linking experimental observations product yields and organic matter degradation. RESULTS Methane sulfide decreased with increasing SO 4 2‐ /COD ratio, while fraction degraded by sulfate reducing bacteria...
Abstract Poultry litter (PL) is one of the drier and bulkier manures produced in intensive agriculture. Land spreading considered most common treatment option for PL; however, this causes large atmospheric greenhouse emissions consequently a high negative environmental impact. PL has several factors that limit its sustainable use as an energy source, thus there still need more studies about waste management. The paper aims at: (i) proposing pathways order to maximise valorisation process,...
Abstract BACKGROUND The aim of the present research was to provide a strategy for start‐up upflow anaerobic sludge blanket (UASB) reactors treating sugar cane vinasse, with emphasis on relevant sulfur compounds along reactor height. To this end, laboratory‐scale UASB started up and its performance under applied conditions studied. RESULTS Biomass able assimilate organic loading rates from 3 10 kg chemical oxygen demand (COD) m R −3 d −1 , reducing VFAs accumulation, while increasing biogas...
This study aimed to determine the cost of lamb produced from different artificial insemination techniques in Santa Inês sheep. The experiment was conducted on a 3 x 2 factorial arrangement, randomized block design. One hundred and two females were divided three groups: cervical with fresh semen - AI or frozen-thawed AIFT laparoscopic LAI. On determination total lamb, variable fixed costs considered. labor suffered great technical variation among as 9.4% IAC, 17.7% IAF e 26.4% IAL. expenses...
The residual sludge from anaerobic digestion known as digestate has been used a valuable biofertilizer, but the effect of substrate, configuration reactor and operating parameter changes quality amounts nutrients in it. Therefore, it is necessary to know its potential characteristic fertilizer apply correctly crops national interest. aim this work was characterize generated three biodigester technologies (fixed dome, floating drum tubular) substrates: swine manure, cow co-digestion manure...
<title>Abstract</title> The seedling of Nicotiana tabacum L. (N. tabacum) holds strategic and economic importance in the product chain due to its vital contributions agronomical yield characteristics final product. This study assessed environmental life cycle impacts three technologies for N. seedlings (traditional seedbed, technified, tray-based). assessment considered main activities within studied system boundaries, insecticides, fertilizers, fungicides, infrastructure, energy,...
