An empiric equation for the latent heat of vaporization of moisture in bananas during its isothermal drying

引用

Agricultural Sciences 2012年第2期3卷 214-220页

作者： Wilton pereira da Silva Cleide Maria Diniz pereira da Silva e Silva Fernando josé de Almeida Gama josivanda Palmeira Gomes Federal University of Campina Grande Campina Grande Brazil

In order to determine the energy needed to artificially dry a product, the latent heat of vaporization of moisture in the product, hfg, must be known. Generally, the expressions for hfg reported in the literature are of the form hfg = h(T)f(M), where h(T) is the latent heat of vaporization of free water, and f(M) is a function of the equilibrium moisture content, M. But expressions of this type contain a simplification because, in this case, the ratio hfg/h would only depend to the moisture content. In this article a more general expression for the latent heat of vaporization, namely hfg = g(M,T), is used to determine hfg for banana. To this end, a computer program was developed which fits automatically about 500 functions, with one or two independent variables, imbedded in its library to experimental data. The program uses nonlinear regression, and classifies the best functions according to the least reduced chi-square. A set of executed statistical tests shows that the generalized expression used in this work given by hfg = g(M,T) produces better results of hfg for bananas than other equations found in the literature.

Towards a Link between Climate Extremes and Thermodynamic Patterns in the City of Rio de Janeiro-Brazil: Climatological Aspects and Identified Changes

引用

Journal of Geoscience and Environment Protection 2023年第8期11卷 131-160页

作者： Wanderson Luiz-Silva Fabricio Polifke da Silva Claudine pereira Dereczynski josé Ricardo de Almeida França Department of Meteorology Institute of Geosciences Federal University of Rio de Janeiro Rio de Janeiro Brazil

Modification signs in extreme weather events may be directly related to alterations in the thermodynamic panorama of the atmosphere that need to be better understood. This study aimed to make a first interconnection between climate extremes and thermodynamic patterns in the city of Rio de Janeiro. Maximum and minimum air temperature and precipitation extreme indices from two surface meteorological stations (ABOV and STCZ) and instability indices based on temperature and humidity from radiosonde observations (SBGL) were employed to investigate changes in the periods 1964-1980 (P1), 1981-2000 (P2), and 2001-2020 (P3). Statistical tests were adopted to determine the significance and magnitude of trends. The frequency of warm (cold) days and warm (cold) nights are increasing (decreasing) in the city. Cold (Warm) extremes are changing with greater magnitude in ABOV (STCZ) than in STCZ (ABOV). In ABOV, there is a significant increase of +84 mm/decade in the rainfall volume associated with severe precipitation (above the 95th percentile) and most extreme precipitation indices show an increase in frequency and intensity. In STCZ, there is a decrease in extreme precipitation until the 1990s, and from there, an increase, showing a wetter climate in the most recent years. It is also verified in SBGL that there is a statistically significant increase (decrease) in air temperature of +0.1°C/decade (-0.2°C/decade) and relative humidity of +1.2%/decade (-3%/decade) at the low and middle (high) troposphere. There is a visible rising trend in most of the evaluated instability indices over the last few decades. The increasing trends of some extreme precipitation indices are probably allied to the precipitable water increasing trend of +1.2 mm/decade.

Objective: To identify the main chemical classes of compounds from aqueous extract of Enterolobium contortisiliquum(E. contortisiliquum) seed bark and to evaluate its antibacterial activity, as well as its potential to increase the activity of antibiotics against strains of Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia ***: Different classes of compounds in the aqueous extract of E. contortisiliquum were evaluated based on the visual changes in the coloration and the formation of precipitate after the addition of specific reagents. The antibacterial activity of the extract and its potential to increase of antibiotic activity of antibiotics drugs, gentamicin and norfloxacin was determined by using the microdilution ***: Our results demonstrated that the following secondary metabolites were presented in E. contortisiliquum seed bark: flavones, flavonols, xanthones, flavononols,chalcones, aurones, flavones and catechins. The extract itself had very low antibacterial activity against all bacterial strains tested(MIC ≥ 1024 μg/m L), but there was an increase in the antibiotic activity of gentamicin and norfloxacin when combined in the subinhibitory concentration(i.e., MIC/8).Conclusions: Our data suggests that E. contortisiliquum seed bark may be an alternative source for new drugs with the potential to increase antibiotic activity against different strains of bacteria.

Determination of the Bromine, Manganese and Antimony in Nicotiana tabacum Solanaceae by Using the Neutron Activation Analysis Technique

引用

Materials Sciences and Applications 2022年第2期13卷 91-106页

作者： Tufic Madi Filho Elson Barros Ferreira josé Roberto Berretta Maria da Conceição Costa pereira Instituto de Pesquisas Energéticas e Nucleares S&atilde o Paulo Brazil Universidade Paulista—UNIP-SP Software Engineering Research Group Paulista University UNIP Campus Tatuapé S&atilde o Paulo Brazil Secretaria da Educaç ã o do Estado de Sã o Paulo S&atilde o Paulo Brazil

Tobacco addiction has been mentioned as a leading cause of preventable illnesses and premature disability. Smoking is the main cause of lung cancer and one of the factors that most contribute to the occurrence of heart diseases, among others. The herbaceous species Nicotiana tabacum is a plant of the solanaceae family used for tobacco production. Some authors have conducted research about heavy metals and the toxicity of tobacco. It is, frequently, found in low concentrations in the ground, and superficial and underground waters, even though they do not have environmental anthropogenic contributions. However, with the increase of industrial activities and mining together with the agrochemical use of contaminated organic and inorganic fertilizers, an alteration of the geochemical cycle occurs. As a consequence, the natural flow of these materials increases and is released into the biosphere, where they are often accumulated in the superior layer of the ground, accessible to the roots of the plants. During planting and plant development, fertilizers and insecticides, including organochlorines and organophosphates, are used;consequently, the smoke from cigarette smoking presents various toxic substances, such as bromine (Br), manganese (Mn) and antimony (Sb), elements studied in this work. The procedures for the preparation of the samples were carried out in our laboratories and submitted to irradiation with thermal neutrons at Nuclear and Energy Research Institute (IPEN/CNEN-SP), in the Atomic Energy Institute IEA-R1 research reactor. The irradiated material was, then, analyzed by gamma spectrometry, using a high purity germanium detector (HPGe).

World Journal of Gastroenterology 2007年第22期13卷 3112-3116页

作者： josé Celso Ardengh César Vivian Lopes Luiz Felipe pereira de Lima Juliano Rodrigues de Oliveira Filadélfi o Venco Giulio Cesare Santo josé Luiz Pimenta Módena Echoendoscopy and Pathology Units from 9 de Julho Hospital and Ribeiro Preto Medical School-USP So Paulo Brazil

AIM： To evaluate the diagnostic accuracy of endoscopic ultrasound-guided fine-needle aspiration （EUS-FNA） for pancreatic solid tumors larger or smaller than 3 cm, and cystic lesions.METHODS： From January/1997 to December/2006, 611 patients with pancreatic tumors were subjected to EUSFNA. The final diagnosis was obtained either by surgery （356 cases） or after a mean clinical follow-up of 11.8 mo in the remaining patients.RESULTS： There were 405 solid tumors, 189 cystic lesions and 17 mixed. Pancreatic specimens for cytological assessment were successfully obtained by EUS-FNA in 595 （97.4%） cases. There were 352 （57.6%） malignancies and 259 （42.4%） benign tumors. Among the malignancies, pancreatic adenocarcinomas accounted for 67% of the lesions. Overall, the sensitivity, specificity, positive and negative predictive values, and accuracy of EUS-FNA were, respectively, 78.4%, 99.2%, 99.3%, 77.2% and 87.2%. Specifically for solid tumors, the same parameters for neoplasms larger and smaller than 3 cm were, respectively, 78.8% ys 82.4%, 100% ys 98.4%, 100% vs 99%, 54.8% vs 74.1% and 83.1% vs 87.8%. For cystic lesions, the values were, respectively, 72.2%, 99.3%, 97.5%, 91% and 92.2%.CONCLUSION： EUS-FNA can be used to sample pancreatic tumors in most patients. Even though the negative predictive value is inadequate for large solid tumors, the results are rather good for small solid tumors, especially concerning the sensitivity, negative predictive value and diagnostic accuracy. Among all pancreatic lesions, EUS-FNA for cystic lesions can reveal the best negative predictive value and diagnostic accuracy, both higher than 90%.

Background： The aim of this study was to estimate variance components and to identify genomic regions and pathways associated with resistance to gastrointestinal parasites, particularly Haemonchus contortus, in a breed of sheep adapted to tropical climate. Phenotypes evaluations were performed to verify resistance to gastrointestinal parasites, and were divided into two categories： i） farm phenotypes, assessing body condition score（BCS）, degree of anemia assessed by the famacha chart（FAM）, fur score（FS） and feces consistency（FC）; and ii） lab phenotypes,comprising blood analyses for hematocrit（HCT）, white blood cell count（WBC）, red blood cell count（RBC）,hemoglobin（HGB）, platelets（PLT） and transformed（log10） egg per gram of feces（EPG_（log））. A total of 576 animals were genotyped with the Ovine SNP12k Bead Chip（Illumina, Inc.）, that contains 12,785 bialleleic SNP markers. The variance components were estimated using a single trait model by single step genomic BLUP ***： The overall linkage disequilibrium（LD） mean between pairs of markers measured by r2 was 0.23. The overall LD mean between markers considering windows up to 10 Mb was 0.07. The mean LD between adjacent SNPs across autosomes ranged from 0.02 to 0.10. Heritability estimates were low for EPG_（log）（0.11）, moderate for RBC（0.18）, PLT（0.17） HCT（0.20）, HGB（0.16） and WBC（0.22）, and high for FAM（0.35）. A total of 22, 21, 23, 20, 26, 25 and 23 windows for EPG_（log）for FAM, WBC, RBC, PLT, HCT and HGB traits were identified, respectively. Among the associated windows, 10 were shown to be common to HCT and HGB traits on OAR1, OAR2, OAR3, OAR5, OAR8 and ***： The traits indicating gastrointestinal parasites resistance presented an adequate genetic variability to respond to selection in Santa Inês breed, and it is expected a higher genetic gain for FAM trait when compared to the others. The level of LD estimated for markers separated by less than 1 Mb indicated that the Ovine SNP12k Bead Chip m
