26. BIOMASS, GAS EXCHANGE AND PRODUCTION OF CHERRY TOMATO CULTIVATED UNDER SALINE WATER AND NITROGEN FERTILIZATION
RESUMO O cultivo de tomate cereja no semiárido do Nordeste brasileiro é limitado pela escassez hídrica, por isso é comum o uso de fontes de águas com elevadas concentrações de sais nessa região, que causam efeito deletério nas plantas, podendo ser amenizado por meio de estratégias de manejo, destacando-se a adubação com nitrogênio.

27. PHYSICAL FRACTIONATION AND CARBON AND NITROGEN STOCKS IN SOIL AFTER POULTRY WASTE APPLICATIONS
RESUMO Resíduos da produção de peru frequentemente são utilizados como fertilizantes em pastagens próximas a regiões produtoras. Esses resíduos podem contribuir para a elevação dos estoques de carbono e nitrogênio no solo. Neste estudo objetivou-se avaliar os efeitos acumulados de nove aplicações de doses de cama de peru nas frações e estoques

28. Production of milk analogues from rice bran protein hydrolysate using the subcritical water technique
Abstract Subcritical water treatment is a useful technique for the extraction of active compounds from biomass materials due to its short processing time, low cost, and environmental sustainability. Defatted rice bran is a by-product of rice bran oil, which still contains protein. In this study, rice bran protein was extracted using subcritical water treatme

29. Evaluating red meat putrefaction in long term storage in freezing condition based on co-variation of major biogenic amines and Total Volatile Nitrogen
Abstract Nearly all of the rejected frozen carcasses in Asian countries are due to their high amount of total volatile nitrogen (TVN). The main aim of this study was evaluating red meat putrefaction based on putrescine and cadaverine content in red meat as major biogenic amines that contributed in TVN content during long-term storage in freezing condition. F

30. Short Circuit and Recovery Time Tests in a helical bifilar R-SFCL module
Abstract Superconducting Fault Current Limiter (SFCL) modules with distinct arrangements have been investigated, seeking design and performance enhancements. In this context, this work aims to propose a design for resistive SFCL (R-SFCL) modules, using RE-Ba-Cu-O high-temperature superconducting tapes (HTS) wound on an alternative support material. An R-SFCL

31. Comparison between barley malt protein quantification methods
Abstract Brazil imports about 60% of all the malt used by the brewing industry which is spread throughout the country. Even though it is an agricultural country, only a small portion of the barley production has the characteristics to produce barley malt for brewing. Seeking supply to the ever-growing demand and reducing the dependency on other countries and

32. GASES DE NITROGÊNIO REATIVO COMO PRECURSORES DO AEROSSOL ATMOSFÉRICO: REAÇÕES DE FORMAÇÃO, PROCESSOS DE CRESCIMENTO E IMPLICAÇÕES AMBIENTAIS
The increased emissions of reactive nitrogen gases from anthropogenic sources to the atmosphere has been pointed out as responsible for triggering a series of environmental problems at the local, regional, and global scale. Among the many consequences associated with the excess of reactive nitrogen in the environment is the increase of atmospheric aerosol fo

33. CONTRIBUTION OF SOIL ATTRIBUTES AND MORPHOLOGICAL VARIABLES TO YIELD OF IRRIGATED GARLIC
ABSTRACT This study aimed to investigate relationships between the soil attributes that most affect garlic yield, which can be useful to choose a new area for the growing of this vegetable. We also aimed to study the effects of irrigation deficit at bulb formation stage (cloves) on final garlic quality and yield. The variables evaluated were garlic yield, ir

34. FUZZY MODELING IN ORANGE PRODUCTION UNDER DIFFERENT DOSES OF SEWAGE SLUDGE AND WASTEWATER
ABSTRACT The present work aimed to develop mathematical fuzzy models to evaluate the effects of different doses of sewage sludge and irrigation with wastewater and potable water. Such models were elaborated from an experiment carried out at the Faculty of Agronomic Sciences, in the Department of Soil and Environmental Resources, from the Sao Paulo State Univ

35. Synthesis of Hydroxybenzodiazepines with Potential Antioxidant and Antifungal Action
Benzodiazepines derivatives are nitrogen heterocyclic compounds that have various industrial, synthetic, and medicinal applications. Therefore, its potential fully justifies every effort towards the improvement of new, selective, and competent production of these heterocyclic compounds. The novelty of this study encompasses the synthesis of new hydroxylated

36. SYNTHESIS, CHARACTERIZATION, DFT MODELING AND IN VITRO ANTIMYCOBACTERIAL ACTIVITY ASSAYS OF A SILVER(I)-ISONIAZID COMPLEX
In the present work, a silver(I) complex with the antimycobacterial drug isoniazid (inh) is described. Elemental and thermogravimetric analyses confirmed a 1:1 metal:ligand ratio for the silver-isoniazid (Ag-inh) complex with molecular composition AgC6H7N3O·NO3. Infrared (IR) analysis suggests a bidentate coordination of isoniazid to silver by the nitrogen
