ABSTRACT: This study evaluated the changes caused by cooking presoaked aged carioca beans in the autoclave steam, focusing on its bioactive components, antioxidant activity, and nutritional compounds. Additionally, to identify which carioca bean cultivar could preserve the most quantity of bioactive compounds in cooked flour. The cooked flours from Imperador had the highest antioxidant activity (DDPH: 10.58 µmolTrolox·g-1, ABTS: 18.71 µmolTrolox·g-1), anthocyanins (8.08 µg·g-1), and total phenolic content (TPC) (36.69 mg·g-1). The cultivar Gol also retained part of these compounds after cooking. The phenolic and saponin profiles of cooked flours revealed a reduction in phenolic compounds such as catechin, epicatechin, and kaempferol and an increase in soyasaponin-Ba and Bb. The samples Notavel, Dama, and Madreperola, presented the highest amount of soyasaponin-A0. Thus, the cooked flours from Imperador and Gol stood out due to their retention of part of their bioactive compounds, such as polyphenols and group B saponins.

ABSTRACT: This research determined the adaptability and stability of soybean yield for organic systems in different environments. Grain yield data (GY, kg ha-1) from experiments with six soybean genotypes evaluated in six environments in Brazil and one environment in Paraguay were used. The experimental design used was randomized blocks, organized in an incomplete factorial scheme, with six environments in Brazil (Toledo- PR, Palotina- PR, Mangueirinha- PR, Três Passos- RS, Passo Fundo- RS, Major Vieira- SC) and one in Paraguay (Bela Vista do Norte- PY) with six soybean genotypes (BRS 284, BRS 391, BRS 511, BRS 523, BRS 525, BRS 535) arranged in four replications per environment. BRS 511 genotype was characterized by high average grain yield and stability by the AMMI method. BRS 284 genotype was identified as the ideal genotype in the GGE biplot method. WAASBY and BLUP index selected BRS511 and BRS284 genotypes.

ABSTRACT: The growing worldwide demand in the pulp market has fostered research that evaluates alternative fiber sources with specific characteristics that attend the needs of the consumer market, with a view to add value to the final product and reduce production costs. Acacia mearnsii De Wild wood is a by-product of the extraction of tannin from the trunk bark, used for firewood, charcoal and pellets. However, its wood is still poorly studied, especially its anatomical characteristics, which can provide important information about its industrial potential. This study evaluated the anatomical characteristics of Acacia mearnsii wood for the production of pulp and paper. Ten trees at approximately seven years old were cut down, five from the seed production area (SPA) and five from the clonal population area (CPA). From each tree, one trunk disc was sectioned at the diameter at breast height (DBH), resulting in 10 (ten) wood samples. From each disc, a sapwood specimen was made oriented in the tangential longitudinal, radial longitudinal and transversal planes, for later obtaining the anatomical cuts and the macerates. The anatomical description of the wood followed the recommendations of the International Association of Wood Anatomists-IAWA. From the dimensions of the fibers, their quality evaluation ratios for the production of pulp and paper were calculated. Results obtained from the anatomical characterization allowed to conclude that the Acacia mearnsii woods from SPA and CPA are indicated as a source of raw material for the pulp and paper production.

ABSTRACT: This study investigated the association between neurological signs as well as plausible risk factors and the seroprevalence of Toxoplasma gondii and Neospora caninum infection in dogs of the Campo Grande region of Mato Grosso do Sul, Brazil. In this study, the dogs were divided into two groups based on the presence and the absence of neurological signs (n=30 in each group). Serological diagnosis was performed using the indirect fluorescent antibody test. In the group with neurological disorders, 23.3% and 30% of the dogs had anti-T. gondii and anti-N. caninum antibodies, respectively. Moreover, three dogs from this group showed co-infection with both protozoa. In the group without neurological signs, 16.7% and 13.3% of the dogs were seropositive for T. gondii and N. caninum, respectively. Although presence of neurological signs was not associated with T. gondii and N. caninum infections (P = 0.747 and P = 0.21, respectively), there was a statistical association between T. gondii seropositivity and peripheral neurological alteration (P = 0.016) among dogs with neurological signs. Raw meat ingestion was the only risk factor associated with the presence of anti-N. caninum antibodies (P = 0.041). Results revealed evidence of exposure to N. caninum and T. gondii in dogs irrespective of the presence of neurological signs. Moreover, this study highlighted the need for serological investigation of T. gondii in dogs with disturbances in peripheral nervous systems and not offering raw meat to animals to avoid the risk of N. caninum infection.

ABSTRACT: Water scarcity associated with irregular rainfall in the semi-arid region of Northeastern Brazil stands out as a limiting factor for agricultural production. Thus, the use of waters with high concentration of salts is an alternative to expand irrigated agriculture in this region. In this context, this study evaluated the water status, intercellular electrolyte leakage, photosynthetic pigments, and gas exchange of ‘BRS SC1’ sour passion fruit as a function of irrigation with water of different levels of salinity and potassium doses. The experiment was carried out in pots adapted as drainage lysimeters under field conditions at the Experimental Farm of the Federal University of Campina Grande in São Domingos - PB, Brazil. The experimental design was randomized blocks, in a 5 × 4 factorial scheme, whose treatments were obtained by combining two factors: five levels of electrical conductivity of irrigation water - ECw (0.3, 1.1, 1.9, 2.7, and 3.5 dS m-1), associated with four potassium doses (60, 80, 100, and 120% of the recommendation), with three replicates. Water with electrical conductivity greater than 0.3 dS m-1 reduced the relative water content, chlorophyll a and chlorophyll b contents, CO2 assimilation rate, and instantaneous water use efficiency of ‘BRS SC1’ sour passion fruit plants. The estimated potassium dose of 85% of the recommendation (equivalent to 293 g per plant per year) mitigated the deleterious effects of salt stress on stomatal conductance, transpiration, internal CO2 concentration, and instantaneous carboxylation efficiency of passion fruit ‘BRS SC1’.

ABSTRACT: This study evaluated the feasibility of abdominal liftfor laparoscopic adrenalectomy and compared it with the conventional laparoscopic technique using pneumoperitoneum with medicinal CO2 in dog cadavers. The total surgical time (TST), adrenalectomy time (AT), and gland integrity after removal were evaluated. Thirty-eight adrenalectomies were performed in 19 cadavers. Regardless of the antimere, the TST was significantly lower in the CO2 procedures than in the lift laparoscopy procedures (P=0.001). When comparing the techniques between antimeres, the TST was significantly higher on the left side with lift laparoscopy than with CO2 (P=0.015) and similar between the techniques on the right side of the animals (P=0.086). In the comparison of AT, regardless of the execution side, no differences were observed between the techniques (P=0.05). The same was observed when AT was evaluated separately using antimeres (P=0.902). Of the 38 adrenals evaluated, 92.1% were removed in a single block, and 32.29% had a superficial lesion in the capsule. There was no difference between the groups in the removal capacity in a single block (P=0.340) and capsule integrity (P=0.287). Abdominal lift for laparoscopic adrenalectomy is a feasible technique in dog cadavers; however, it requires a longer surgical time than the conventional technique. The traction force used to elevate the abdominal wall must be evaluated.

ABSTRACT: The present study evaluated germination, production, and morphological composition of Urochloabrizantha intercropped with corn and sorghum; and silage fermentation losses and aerobic stability of intercrop silage using microbial inoculant. Twenty experimental parcels (5.0 × 3.6 m) were used in a blocked randomized design to evaluate four treatments obtained from a 2 × 2 factorial arrangements: I) crop material (corn vs. sorghum) and II) Brachiaria (U. brizantha) establishment (present vs. absent). Corn- and sorghum-brachiaria integrated systems showed similar brachiaria germination, forage yield, and morphological composition. There was no crop and brachiaria interaction effect on the variables related to corn and sorghum plants and the total productivity. Brachiaria decreased the stem diameter and increased the population of maize and sorghum plants. However, it did not affect systems productivity. Microbial inoculation did not affect corn silage effluent losses and reduced sorghum silage effluent losses. In corn silage, brachiaria did not affect gas losses, while in sorghum silage, brachiaria increased the gas losses. Total losses were higher in sorghum silage than in corn silage, which resulted in a lower DM recovery. The treatments did not affect the pH of the silage after aerobic exposure. However, brachiaria increased silage temperature evaluated at 32 and 40 hours after aerobic exposure. Thus, corn or sorghum consortium has similar brachiaria morphological composition and productivity. Moreover, in intercropped silage, brachiaria increases effluent losses and reduces silage aerobic stability.

ABSTRACT: This article analyzed the international competitiveness of exports of forest products from 2008 to 2018. The information is available in the Food and Agriculture Organization (FAO) and the indicators used were: revealed comparative advantage (RCA), trade openness index (Oi) and the contribution to trade balance index (CTB). Results showed that the exportation of forest products are competitive, in addition gains in competitiveness have been observed by the RCA and in Europe, countries had losses in detriment of the financial crises and austerity measures adopted. All countries showed a low degree of openness by the Oi and had a comparative advantage by the CTB, except for China and Germany. It is concluded that the countries with bigger comparative advantages in the exportation of forest products were the ones that had contributed more for its commercial balance.

Results showed that the exportation of forest products are competitive, in addition gains in competitiveness have been observed by the RCA and in Europe, countries had losses in detriment of the financial crises and austerity measures adopted. All countries showed a low degree of openness by the Oi and had a comparative advantage by the CTB, except for China and Germany. It is concluded that the countries with bigger comparative advantages in the exportation of forest products were the ones that had contributed more for its commercial balance.","PeriodicalId":10308,"journal":{"name":"Ciencia Rural","volume":"1 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2023-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67637073","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ABSTRACT: The development of rural tourism destinations in China is confronting multiple issues, including blind expansion and a repetitive developmental model, causing the sector to enter a vicious competition cycle. The perception among tourists of rural tourism destinations, and their willingness to revisit places will provide insights for service providers that will enable them to form better strategies to stand out in the fiercely competitive market. Understanding tourist perception will enable providers to contribute to the construction of rural tourist destinations. Taking Ma Wei Yi Folk Culture Village as a case study, this paper combines the development status of rural tourism in Ma Wei Yi, obtains first-hand data through questionnaire interviews, verifies the research hypothesis, and uses Pearson coefficient to carry out correlation analysis. The paper concluded that tourists’ rural perception has a positive and strong impact on their willingness to revisit, and its factors have different impacts. According to the empirical results, tourist destination providers should pay attention to rural perceptual development in their follow-up development and operation processes. They can effectively attract tourists to visit multiple times, enhance tourist’s sense of enjoyable experience, and achieve sustainable development.

ABSTRACT: There is a growing demand for authentic products that provide sensory characteristics combined with health benefits that current studies have focused on. This review addressed the technological aspects involved in producing craft beers and the use of various fruits in developing new products with higher added value. The information was collected by researching scientific databases such as Scopus, websites, and the CAPES catalog of Theses and Dissertations. Thus, this study sought to obtain more information to promote discussion about the possibilities of adding various fruits in developing beers with a strong cultural appeal, high nutritional and marketing value, and that can also be categorized as a functional food.
