Carbonized rice husk as an alternative substrate for Ocimum basilicum L. seedling production

The substrate used in seedling production plays a major role in the initial plant development. In this sense, the objective was to evaluate the emergence capacity and establishment of basil seedlings in different proportions of alternative substrates based on charred rice husk and commercial substrate S10®. The experiment was carried out in expanded polyethylene trays, using basil seeds (Horticeres seeds®), which lasted 28 days. The experimental design was completely randomized, with five treatments (T1: 100 % commercial substrate (BCS); T2: 80 % BCS + 20 % Charred rice husk (CRH); T3: 60 % BCS + 40 % CRH; T4: 40 % BCS + 60 % CRH; T5: 20 % BCS + 80 % CRH) and three repetitions. Were evaluated leaf number, shoot length, root length, root dry mass, shoot dry mass, leaf area, germination, germination speed index, substrate physical analysis (density (dry and wet)), total porosity and aeration space, and chemical analysis (hydrogen potential (PH), and electrical conductivity (EC)). It was observed in the results that the substrate type interferes in the development and quality of the basil seedling. In the shoot lenght parameter, the treatment with 40 % BCS + 60 % CRH (T4) had a significant difference compared to the other treatments. Among the substrates, the best seedling performance was observed in the substrate with 80 % BCS + 20 % CRH (T2), which provided better seedling quality in relation to the other treatments.

Abstract Objective - This study compared the quality and helpfulness of traditional book review sources with the online user rating system in Amazon.com in order to determine if one mode is superior to the other and should be used by library selectors to assist in making purchasing decisions. Methods - For this study, 228 reviews of 7 different novels were analyzed using a content analysis approach. Of these, 127 reviews came from traditional review sources and 101 reviews were published on Amazon.com. Results - Using a checklist developed for this study, a significant difference in the quality of reviews was discovered. Reviews from traditional sources scored significantly higher than reviews from Amazon.com. The researcher also looked at review length. On average, Amazon.com reviews are shorter than reviews from traditional sources. Review rating—favourable, unfavourable, or mixed/neutral—also showed a lack of consistency between the two modes of reviews. Conclusion - Although Amazon.com provides multiple reviews of a book on one convenient site, traditional sources of professionally written reviews would most likely save librarians more time in making purchasing decisions, given the higher quality of the review assessment.

Studying particle size distribution is important to understand soil structure and formation processes. This research aimed to assess the fractal dimension of soil texture in Indian Dark Earth (IDE) areas in southern Amazonas state under different land uses, as follows: two areas in the municipality of Apuí, one growing cocoa and the other coffee; a grassland area in the municipality of Manicoré; and a forest area in the municipality of Novo Aripuanã. A sampling grid containing 88 collection points (intersecting points on the grid) was established in each area, measuring 80 x 42 m for the cocoa and coffee-growing sites, and 80 x 56 m and 60 x 42 m for the grassland and forest areas, respectively. Soil samples were collected in soil core and as clumps at a depth of 0.0-0.20m to determine the structural physical properties and texture of the soil. The following physical attributes were assessed: texture (PSD), bulk density (BD), macroporosity (Macro), microporosity (Micro), total porosity (TP) and aggregate stability (GMD and WMD). The fractal dimension (D) of the soil texture was determined, followed by analysis of variance and comparison of the means using Tukey’s test (p≤0.05). Pearson’s correlation was applied to assess the correlation between variables. There was a significant difference between the IDEs studied, with a higher D value in the cocoa-growing area in relation to the other sites. Additionally, the larger the clay fraction, the higher the D value. Fractal dimension (D) showed a positive correlation with sand, clay, BD, Macro, GMD and WMD, and a negative correlation with silt, micro, TP. Based on the D values obtained, the ADE cultivated with cocoa showed superior quality in relation to the other areas studied.

The objective of this work was to verify the influence of planting density on productivity and fruit quality of the fig tree. The design was used in three blocks, the plants of the cultivar Roxo de Valinhos were submitted to three planting spacings: 5 x 0.5 m; 5 x 1.0 m; and 5 x 1.5 m. The evaluated characteristics were: length of branches; average weekly growth of branches; fruit size; average fruit weight;soluble solids (°Brix); yield of mature fruits; productivity of green fruits; accumulated productivity; and dry mass of fruits.The length of the branches was not influenced by planting spacing, the plants conducted at lower densities presented higher productivity, both of green fruits and accumulated productivity.Plants submitted to lower planting density produced fruits with higher dry matter, but these were smaller in size, but without significant difference for those submitted to lower density. It wasconcluded that productivity is directly affected by fig planting density, but not all the qualitative aspects of the fruits were affected.

The contribution of the physiologic and cognitive processes is important for increasing the quality of the education and occupational productivity. The new researches done indicate that exercising frequency and emotional intelligence level have precious contributions on the occupational performances of the individuals. The purpose of this research was determined as evaluating the sporting situation and emotional intelligence levels of adults in different occupational groups. 586 individuals participated in the research, who works in various professions in Bartın Province. The information on the participant group and the other variables of the research was analyzed via descriptive statistic techniques. For evaluating the data, SPSS 21.0 package software was used and for analyzing the data, descriptive statistics, independent t-test and one-way variance analysis (ANOVA) techniques were used. As a result of the data obtained, no significant difference was encountered in the emotional intelligence sub-dimensions and total scores depending on the sporting situation of the participants (p > 0.05). As a result of the analyses done for the gender variable, significant differences were obtained on behalf of the women and it was seen that emotional intelligence total scores of the female workers are higher compared with the male workers (p < 0.05). For the finding where the relations between age variable and emotional intelligence was evaluated, it was seen that there is a significant decrease in the emotional intelligence level with the increase in age (p < 0.05). This decrease was tried to be explained with occupational exhaustion. At the same time, the finding was arrived that the total emotional intelligence scores of the participants who work as teacher, compared with the other professions, is higher with a significant level compared with the other profession groups (p < 0.05). The findings of the research were discussed in the light of the literature and recommendations were offered for contributing to the new researches to be made.

Germination And Growth

Albizia niopoides (Bentham) Burkart, known as farinha seca, is an arboreal, deciduous and pioneer plant that can be found in the semi-deciduous forest in the Paraná basin. The study on the germination and growth of the plant is fundamental for better knowledge about the establishment and regeneration of the species. Aiming to verify the germination of A. niopoides and subsequent growth, green seeds and brown seeds were germinated in a germination chamber and growth parameters were evaluated at 60, 90, and 180 days after transplanting (DAT) in a greenhouse. There was no significant difference in germination percentage between green and brown seeds. However, lower levels of mean germination times and higher levels of germination speed index were observed for brown seeds. At 180 DAT, plants showed higher shoot dry mass, root dry mass, total dry mass, number leaves and height, with no significant difference between 60 and 90 DAT for total dry mass, root dry mass and root length. The values of stem height/diameter and Dickson quality index, associated to the other growth parameters, indicate quality of the seedlings for field planting at 180 DAT.

Competitive Behaviour

AbstractData from several field experiments support the existence of a trade-off between number and quality of offspring. However, long term effects of brood size on fitness related traits of offspring have been a relatively neglected area of research. In a laboratory experiment the effect of manipulated brood size on subsequent competitive ability of adult offspring was investigated. Zebra finches, Taeniopygia guttata, were reared in small or large broods and young were exchanged in such a way that natural siblings from different rearing conditions could be compared. Competitive behaviour was assessed in two different contexts: competition for food (both sexes tested) and competition for mates (only males tested). There was no significant difference between males from small and large broods in number of succesfull attacks (after which the other male moved away) during male-male aggressive interactions provoked by the presentation of a female in an adjacent cage. Nor did brood size affect latency to eat, time spent eating or success at displacing the other bird from the feeder during food competition tests. The results thus suggest consistently that later competitive ability of offspring is not affected by brood size in this species.
