title: Effect of humic acid on the growth of seedling tomato (Solanum lycopersicum) and melon Cucumis melo)

description: Abstract This study evaluated the effect of HS extracted from mineral coal on the growth of tomato (Solanum lycopersicum) and melon (Cucumis melo) plants to determine the role that humic substances (HS) play as promoters of plant growth. Three concentrations of HS were evaluated in 200 grams of soil. The fertilizer (urea 0.3%) and humic acid in concentrations of 0.05%, 0.1%, and 0.2% were added directly and at the same time to the amount of soil, using a control sample without the addition of humic acid. Increase measurements were made at three-day intervals up to 45 days. Plants treated with high concentrations of HS demonstrated a significant increase in roots (p&gt;0.05). In both plants, the concentration of 0.2% in HS showed the greatest increase in growth, with the melon plant showing the greatest variation as time passed, with its highest peak in 36 days (13.1 ± 0.05cm) of the experiment, while in the tomato plant the maximum growth occurred in 30 days (9.2 ± 0.01 cm). The Dunnett test showed that there was no statistically significant difference between the control and the concentrations of 0.05% and 0.1% (p&gt;0.05), while among the control and the soil sample with a concentration of 0.2% there was a statistically significant difference (p&lt;0.05). The results show a notable influence of humic acid on the growth of the studied plants, especially at high concentrations.

title: Structure of Planning and Control Artifacts and their Accuracy in Brazilian Family Businesses

description: ABSTRACT Objective: the accuracy of planning and control artifacts is fundamental for bringing assertiveness to the organizational management process. The utility of the artifacts is questioned when the desired accuracy is missing. This research aims to identify the relationship between the artifact structure, the market assumptions, and the accuracy of the performance variables with a view to adapting the artifact profile to the desired impact over performance accuracy. Methods: this is a quantitative study based on convenience sampling and the data analysis methods used were structural equation modeling and necessary condition analysis. Results: within a sufficiency logic, the results support adherence between the planning and control artifacts, but not their relationship with performance accuracy. However, when analyzing the necessity logic, the artifacts become a necessary condition for a high level of performance accuracy. Conclusions: we show that the planning and control structure is consistent for achieving accuracy, but defining the desired level of deviation tolerance is a fundamental condition for the efficiency level of the management process. The more demanding the organization is in terms of deviation tolerance, the greater the need for artifacts.

title: Investigation of new natural coagulant - cationic hemicellulose associated with cationic tannin - for coagulation/dissolved air flotation (C/DAF) in the treatment of industrial effluent

description: Abstract The use of plant-based coagulants (natural coagulants) in wastewater treatments has potential advantages over the inorganic coagulants used commercially. This study evaluated organic coagulants cationic hemicelluloses (CH) synthesized from peanut shell and associated with commercial cationic tannin (TSG) for use as the primary coagulation/flocculation treatment, followed by solid-liquid separation via sedimentation/flotation by dissolved air (DAF). The assay was carried out in a jar test on effluent from a multinational industry in the grain processing sector, located in the city of Uberlândia-MG. Coagulation diagrams were determined using the data spatial interpolation method of the Kringing regression model and the Tukey test was used to assess the difference in the results obtained. The optimum removal points of turbidity removal efficiency (TRE), greater than 98%, were achieved for the TSG/CH association with 200 mg L-1 (pH 10.72), 350 mg L-1 (pH 9.72), 500 mg L-1 (pH 9.56) in sedimentation. For the separation by DAF, the association of TSG/CH resulted in TRE values greater than 95% at dosages of 350 mg L-1 (pH 9.59) and 500 mg L-1 (pH 7.92). Furthermore, the results indicate that the associated use of TSG/CH, a coagulation aid, favored the coupling of the DAF bubble-particle, resulting in a smaller volume of sludge. In addition, CH expanded the action of TSG to the basic region.

title: RING CURRENT IN ANTHRACENE AND PHENANTHRENE: CORRECTION TO HÜCKEL PARAMETERS

description: Excessive degeneracy in the ground state of the π-electron energy levels of anthracene was removed using the Hückel method by correcting the Coulomb integral of the four central carbon atoms. A further correction to the resonance integral was proposed based on the ring-current model, which describes the π-ring current flow along the molecule’s perimeter, by introducing a new parameter for the bridge carbon atoms expressed as a fraction of the resonance energy. The solution to the Hamiltonian was obtained based on the symmetry group theory, which provides the advantage of solving the determinant matrix or secular equations in a particular irreducible representation with a relatively small matrix dimension. The results were further analyzed to determine the bond order and bond length. The values of the harmonic oscillator model of aromaticity, GEO, and EN indices of aromaticity and their ratio for the central and outer rings of benzene were used to evaluate the validity of the correction. Applying the same method to phenanthrene as a topological analog of anthracene allows for an interesting comparison of the stabilities of the two molecules.

title: Virtual reality as an intervention tool for upper limbs in Parkinson’s disease: a case series

description: ABSTRACT Parkinson’s disease (PD) is a neurodegenerative disorder in which dopaminergic loss occurs in the basal nuclei region. One major complaint associated with PD is upper extremity motor deficits (UE), frequently reported in difficulties to perform activities of daily living (ADL), which may negatively affect quality of life. In recent years new technologies have emerged to assist the UE rehabilitation process in PD, such as virtual reality. Therefore, this study sought to verify the effects of an intervention in the UE with semi-immersive virtual reality equipment on ADLs and quality of life of individuals with PD. Six individuals with PD were selected for intervention, and evaluated by the Mini Mental State Examination, the Hoehn & Yahr Scale, the Unified Parkinson’s Disease Rating Scale (UPDRS), the Parkinson’s Disease Questionnaire (PDQ-39) and the test d’évaluation des membres supérieurs de personnes âgées (TEMPA). The interventions lasted 27 minutes per session, twice per week, for 5 weeks, using the Leap Motion Controller. Individuals showed improvement in muscle strength, muscle endurance, ADLs, and quality of life, all statistically significant. In conclusion, the protocol based on virtual reality applied to the upper limbs effectively improved the activities of daily living and quality of life in individuals with PD.

title: Between mountains and walnut trees: the history of the rural elementary school “heroes children” of the town el pueblito, Santa María Del Río, Mexico

description: ABSTRACT In this article I present the historical process of the multigrade rural primary school “Heroes Children”, located in the town of El Pueblito, in the municipality of Santa María del Río, San Luis Potosí, Mexico, from its foundation (1933) to date. In order to understand how its journey through time has been in relation to the construction of the representations that students, teachers and parents, at different times, have elaborated on it. To carry out this research, based on a documentary and narrative inquiry, I have resorted to local archives, oral testimonies of students, teachers and parents, and photographs. In this sense, especially through the intersection of narratives with official documents, this contribution broadens the horizons of historiographic “creation” and broadens the historian’s “office”, from the possibility of operating with a variety of sources, as well as understanding life stories of teachers, biographical narratives and their representations of the multigrade rural primary school “Heroes Children”. Finally, it turns out that given the significant proportion of the educational service provided by multigrade schools to the rural child population in Mexico, and even though they represent the only opportunity of access to formal education for many students, this type of rural school and the teachers that they work there, they continue to be invisible to educational policy.

title: Seed vigor, genotype and proline in common bean seedling formation under drought and saline stress

description: ABSTRACT Abiotic stresses, especially water and saline stress, are the main causes of reduced field emergence percentage. Several studies have associated the higher concentration of proline with the tolerance of cultivars to these stresses. However, one needs to determine how genotype and seed vigor act during seedling formation in the presence of stresses and how proline concentration interacts with these factors. The objective of this work was to evaluate the relationships of proline with genotype and seed vigor in seedling formation under drought and saline stress. The genotypes BAF07, BAF13, BAF23, BAF42, BAF44, BAF55 and BAF112 were used. They were subjected to germination tests under water and saline stress. At ten days after sowing, the following parameters were assessed: length, seedling dry mass and capacity to mobilize reserves, as well as the free proline content of the seedlings. Seed vigor and tolerant genotypes may help overcome water and saline stresses, and they should be used as a strategy during sowing. Also, higher proline concentrations are not associated with higher either vigor of the seed lot or tolerant genotypes.

title: The body asks and the mind judges: the episode of food craving, its triggers and nutritional treatment

description: ABSTRACT Food desires are defined as motivations that drive the search for and consumption of food. However, when domains of intensity and urgency are activated, these desires can become intense (i.e. food craving), being then characterized by episodes or cognitive events loaded with affectivity, in which food is associated with obtaining pleasure or relief, which is the only attentional focus. Specificity and urgency mark the differentiation between food desires and cravings. The process of elaboration with vivid images, the retention in working memory, the emergence of a negative affect state (awareness of the lack), and a committed attentional focus to seek food are characterized as stages of an episode of food craving. Individuals with eating disorders have the lowest levels of food craving when it comes to anorexia nervosa and the subsequent increase to bulimia nervosa and binge eating disorder. Some environmental and cultural triggers and internal factors of cognition and emotions play a crucial role in the emergence of food craving episodes. The external factors include positive/negative events, food environment, advertisements, cultural beliefs about food, specific locations, and food itself. The internal factors comprise dietary restriction, food reward, impulsivity/inflexibility, emotions, thoughts and feelings about food, hunger/satiety/appetite, and anxious/depressive symptoms. Treatment involves the association of flexibility, awareness, and questioning strategies about dietary practices based on three principles: unconditional permission to eat, eating more for physical than emotional reasons, and tuning in with the body’s signs of hunger and satiety (intuitive eating).
