Relationship between the soluble solids metric Brix and other traits in Capsicum peppers
No full textThe present study was conducted to clarify the relationship between fruit Brix and other chemical components related to taste in chili peppers and to clarify how Brix, which changes in response to environmental stress, is related to other traits such as yield. The experiments were conducted from 2015 to 2019. In experiment 1, 39 varieties of Capsicum annuum were cultivated in 2015 and their pungency and the taste components were evaluated. Relationship of pungency and taste components among varieties were also investigated. In experiment 2, Japanese chili pepper cultivars ‘Manganji’, ‘Fushimiamanaga’ and ‘Botankosho’ were grown under several stress conditions from 2015 to 2019 to determine the relationships of pungency and the taste components in each individual variety. In experiment 3, we observed the effect of stress conditions on plant growth performance and yield using drought stress and salinity stress on ‘Shishito’, ‘Sapporo’ and ‘Botankosho’ cultivars. In experiment 1, although significant positive correlation was found between total sugar content and glucose content in all groups, there was no significant positive correlation between Brix and total sugar content. In experiment 2, a significant positive correlation was found between total sugar content and Brix in all cultivars under all stress conditions. Moreover, a significant positive correlation was found between total sugar content and Brix in each variety. These results clarified that it was not appropriate to use Brix for the comparison of varietal difference of total sugar content but that it was possible to estimate the differences among treatments and individuals within the same variety. In experiment 3, we also found that stress during cultivation increased Brix and capsaicinoid content, and decreased yield, fruit size, and number of leaves. The stress induced increase in Brix because of reduced yield and fruit size, and the effect of reduced photosynthetic ability on Brix due to reduced number of leaves seemed rather small.Article信州大学農学部AFC報告 19: 55-69(2021)departmental bulletin pape

Mandarin Market Segments Based on Consumer Sensory Evaluations
No full textNinety-five consumers in seven grocery stores tasted unidentified peeled sections of three mandarins (a tangerine, a satsuma, and a clementine), and provided demographic and purchase information. Forty-four percent of the respondents preferred tangerines, 34 percent satsumas, and 22 percent clementines. The probability of preferring each of type of mandarin was estimated from internal quality analysis of paired samples, as well as from demographic and purchase responses. Model simulations were used to recommend harvest standards for satsumas based on Brix-to-acid ratios.Demand and Price Analysis, Food Consumption/Nutrition/Food Safety,
Evaluation of brix refractometry to estimate immunoglobulin g content in buffalo colostrum and neonatal calf serum
No full textBrix refractometry has been widely demonstrated to be a useful tool for monitoring colostrum management program and passive immunity transfer (PIT) in Bovines, but its suitability has never been verified in Buffalo. Therefore, the objective of this study was to evaluate the utility of a simple and rapid tool such as a digital Brix refractometer to estimate colostrum quality and for evaluating the success of passive transfer of immunoglobulin G (IgG) in Buffalo calves. The optimal cut points levels for Brix Refractometry for distinguishing good‐ and poor‐quality colostrum and for assessing the adequacy of passive immunity transfer in calves were determined. For this aim, 26 first‐milking maternal colostrum (MC) were collected from first‐calf heifers. Blood samples were obtained from their calves at birth (T0) and 72 hours after (T3). Colostrum and Serum IgG content were determined by indirect enzyme‐linked immunosorbent assay (ELISA), whereas total protein (TP, g/dL) and percentage Brix (%Brix) by means of a digital Brix refractometer. The mean colostrum IgG was 64.9 ± 29.3 mg/mL. The mean serum %Brix at T3 was 9.6 ± 0.9 %. The mean serum IgG content at T3 was 11.1 ± 2.0 mg/mL. Pearson’s correlation coefficient (rp) was determined between Brix and ELISA measurements: colostrum %Brix showed a significant correlation with serum %Brix (rp = 0.82, p < 0.001); serum %Brix was highly correlated with serum TP (STP, g/dL) (rp = 0.98, p < 0.001) and serum IgG (mg/mL) (rp = 0.85, p < 0.001). A cut point of 18% Brix to estimate samples of MC ≥ 50 mg/mL from first‐calf heifers was more appropriate for the buffalo. A cut point of 8.4% Brix resulted in the greatest percentage of calf serum samples being correctly classified. Based on our findings, a digital Brix refractometer could be a useful tool to monitor colostrum quality and to estimate PIT in Buffalo calves
Short communication: Comparative estimation of colostrum quality by Brix refractometry in bovine, caprine, and ovine colostrum.
No full textNewborn ungulates depend on the timely supply of colostrum containing sufficient immunoglobulins to obtain passive immunity against disease. Brix refractometry enables a rapid on-farm estimation of colostrum quality and has been intensively studied in bovines. However, the suitability of Brix refractometers for assessing colostrum quality in goats and ewes has been scarcely evaluated. The present study compared bovine, caprine, and ovine colostrum quality estimation using an optical Brix refractometer. In addition, between-species variations in the relationships between Brix values and colostrum constituents (IgG, fat, protein, and lactose) and the accuracy of Brix refractometry at different cutoff values were evaluated by a receiver operating characteristic curve analysis. We measured the Brix value and contents of IgG, fat, protein, and lactose in 324 colostrum samples (108 cows, 116 does, and 100 ewes). Thresholds for classification of good colostrum quality (as determined by ELISA) were set at 50 mg IgG/mL in cows and 20 mg/mL in does and ewes. Bovine colostrum showed the greatest IgG concentrations compared with caprine and ovine colostrum. Fat and protein content was higher in sheep colostrum compared with the other species, whereas the highest lactose concentrations were detected in goat colostrum. Brix values ranged from 11.4 to 34.6% (22.1 ± 4.2%; mean ± standard deviation), 15.4 to 40.0% (28.5 ± 6.8%), and 8.8 to 39.8% (21.6 ± 5.3%) in bovine, ovine, and caprine colostrum, respectively. In all 3 species, Brix was highly correlated with IgG and protein concentrations (cows, r = 0.83 and 0.98; goats, r = 0.83 and 0.89; sheep, r = 0.75 and 0.87). Optimal cutoff points for greatest accuracy of Brix measurements were 19.3% Brix in cows [with 87.1% sensitivity (Se) and 100% specificity (Sp)], 20.7% Brix in does (with 53.5% Se and 100% Sp), and 26.5% Brix in ewes (with 75% Se and 91.3% Sp). In conclusion, Brix refractometry is an acceptable tool for on-farm estimations of colostrum quality in does and ewes despite distinct between-species variations in colostrum composition
Paratext
No full textIn her chapter on “Paratext,” Louise Brix Jacobsen examines how fictionality as a rhetorical strategy helps us understand the functioning of specific paratext-text relations. Through various text examples and a case study of the Nat Tate biography hoax (William Boyd, 1998), Jacobsen shows the importance of the movement from classification to functioning and thus from a text-based approach to a communication-based approach. The study shows that paratextual signals can be multiphased or delayed and make the receiver participate in a meaning-creating negotiation where fictionality is ascribed retrospectively in service of global communicative aims. Jacobsen concludes by arguing that future research in fictionality must take into account that fictionality is operative and relevant even though and sometimes particularly when it is not ascribed immediately
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Sensors and Instruments for Brix Measurement: A Review
No full textQuality assessment of fruits, vegetables, or beverages involves classifying the products according to the quality traits such as, appearance, texture, flavor, sugar content. The measurement of sugar content, or Brix, as it is commonly known, is an essential part of the quality analysis of the agricultural products and alcoholic beverages. The Brix monitoring of fruit and vegetables by destructive methods includes sensory assessment involving sensory panels, instruments such as refractometer, hydrometer, and liquid chromatography. However, these techniques are manual, time-consuming, and most importantly, the fruits or vegetables are damaged during testing. On the other hand, the traditional sample-based methods involve manual sample collection of the liquid from the tank in fruit/vegetable juice making and in wineries or breweries. Labour ineffectiveness can be a significant drawback of such methods. This review presents recent developments in different destructive and nondestructive Brix measurement techniques focused on fruits, vegetables, and beverages. It is concluded that while there exist a variety of methods and instruments for Brix measurement, traits such as promptness and low cost of analysis, minimal sample preparation, and environmental friendliness are still among the prime requirements of the industry.Publishe
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
