title: The Contribution of Mechanical Spectroscopy to Understanding Grain Boundary Sliding

description: This review paper shows that grain boundary sliding (GBS) is a general phenomenon occurring in all classes of inorganic materials: ceramics, metals and composite materials. The occurrence of relaxations attributed to GBS is also quite general and therefore the mechanical spectroscopy constitutes a sensitive and universal technique to study such phenomenon. GBS is widely observed in ceramics. It can be due to the presence of an amorphous layer between the grains as in zirconia or to dislocations, as in alumina. In each case, a high temperature GBS peak has been identified. In metals, GBS is observed in some deformed materials but the correlation of such phenomenon with internal friction peaks has been controversial. In 1941, C. Zener describes a geometrical model of GBS that could give rise to a relaxation mechanism. In 1947, Kê observed a large relaxation peak in polycrystalline aluminum. This peak being absent in single crystals, the relaxation was attributed to GBS. Today, the Zener model can still be used in most cases for relaxations occurring in the grain boundaries. Instead, according to the grain boundary type, the material or the temperature, either dislocations or the gliding of a disordered layer produce the grain boundary relaxations.

title: OXYGEN UPTAKE AND RESISTANCE EXERCISE METHODS: THE USE OF BLOOD FLOW RESTRICTION

description: ABSTRACT Introduction: The literature has shown that a gap is identified regarding the acute effects of blood flow restriction training on aerobic variables. Objective: to analyze oxygen consumption (VO2) during and after two resistance training sessions: traditional high intensity and low intensity with blood flow restriction. Methods: After one-repetition maximum tests, eight male participants (25.7±3 years) completed the two experimental protocols, separated by 72 hours, in a randomized order: a) high intensity training at 80% of 1RM (HIRE) and b) low intensity training at 20% of 1RM combined with blood flow restriction (LIRE + BFR). Three sets of four exercises (bench press, squat, barbell bent-over row and deadlift) were performed. Oxygen consumption and excess post-exercise oxygen consumption were measured. Results: the data showed statistically significant differences between the traditional high intensity training and low intensity training with blood flow restriction, with higher values for traditional training sessions, except for the last five minutes of the excess post-exercise oxygen consumption. Oxygen consumption measured during training was higher (p = 0.001) for the HIRE (20.32 ± 1.46 mL·kg-1·min-1) compared to the LIRE + BFR (15.65 ± 1.14 mL·kg-1·min-1). Conclusion: Oxygen uptakes rates during and after the exercise sessions were higher for the high intensity training methodology. However, when taking into account the volume of training provided by both methods, these differences were attenuated. Level of Evidence III - Non-consecutive studies, or studies without consistently applied reference stand.

title: Translation and Transcultural Adaptation of the Brazilian Version of the Schutte Self-Report Emotional Intelligence Test

description: ABSTRACT BACKGROUND Recent studies showed that emotional intelligence (EI) could improve medical education and professional practice. There were no instruments validated for Brazilian Portuguese to evaluate EI level. OBJECTIVE To translate and cross-culturally adapt the Schutte Self Report Emotional Intelligence Test (SSEIT) for Brazilian Portuguese. METHODS The translation and cross-cultural adaptation was performed in six steps: translation, synthesis, back translation, expert committee review, pretesting and elaboration of the final version. A Brazilian psychologist and an English Teacher, both fluent in English, performed the translations from English to Portuguese. Two native English speakers who were not familiar with the questionnaire performed the back translations. The authors composed the expert committee review. The internal consistency and reliability of the final version was tested by Cronbach’s alpha (Ca). Values of ≥ 0.70 were considered acceptable. The pretesting was done with medical students and resident doctors, who answered the test and rewrote the sentences in their own words. RESULTS The Portuguese SSEIT translated version had 100% semantic and idiomatic equivalence. The comparison between the back translated versions and the original showed slight semantic discrepancies in four questions, therefore the texts were adjusted. The pretesting version was applied to 41 volunteers, after signing an Informed Consent Form. Seven questionnaires were eliminated as they were not filled out properly. Analyses of the rewritten sentences showed slight discrepancies in the same four questions of the back translations, and were again adjusted. The Ca was 0.786 for the whole questionnaire and ranged from 0.763 to 0.798 between the questions. CONCLUSION The translation and cross-cultural adaptation of the SSEIT for Brazilian Portuguese was a success, and showed acceptable internal consistency and reliability according to Cronbach’s alpha test.

title: Zeta potential and electrophoretic mobility for the recovery of a saline soil with organic amendments

description: ABSTRACT The accumulation of salts in the soil profile produces conditions that affect the growth of crops. The effects of these conditions on crops and the intensity of these effects depend on the quantity and type of salts that predominate and are also influenced by soil characteristics and climate, among other aspects. The salinization of agricultural soils is a serious problem facing agriculture today. The use of organic amendments has increased in recent years, acting on the texture of the soil, correcting compaction or granularity problems, and influencing chemical and/or biological reactions. The objectives of this work were to analyze the use of compost and vermicompost using different analysis techniques to determine the influence of conditions on the remediation of a saline soil. In saturation extracts of soil, compost, and vermicompost, a Zeta potential value 2.34-2.44 times more negative (more-stable colloids) than that in the soil colloids was observed in the amendments. The values of electrophoretic mobility were more negative in the organic amendments compared with the soil. This is the first time that these parameters have been reported for these purposes and for a saline soil. In this study, the soil has low organic matter content (1.65%), so these amendments are expected to improve soil quality and texture, achieving the recovery of saline soils.

title: Degradation Enhancement as the Mechanism of Resistance to Imazethapyr in Barnyardgrass

description: ABSTRACT: Non-target site (NTS) herbicide resistance by degradation enhancement is an increasing problem in several weeds around the world. In this study, the occurrence of degradation enhancement by cytochrome P450 monooxygenases (cytP450) was evaluated as the mechanism of resistance to imazethapyr in barnyardgrass. The cytP450 inhibitors malathion and piperonyl butoxide (PBO) and the inducer naphthalic anhydride (NA), applied in mixture or sequentially with imazethapyr, were evaluated on imidazolinone-susceptible and -resistant barnyardgrass byotipes. In addition, the degradation of imazethapyr was analyzed in plants treated with imazethapyr applied alone or two hours after malathion or NA. The spraying of malathion and PBO reduced the resistance factor (RF) from 15.92 to 3.44 and 4.99, respectively, in the resistant population PALMS01. Conversely, the cytP450 inducer NA increased the RF from 4.45 to 8.32. Malathion increased imazethapyr concentrations in resistant barnyardgrass in comparison with plants sprayed with the herbicide alone, indicating the inhibition of imazethapyr degradation. The simultaneous spraying of malathion and imazethapyr was less efficient than the previous application of this cytP450 inhibitor. These results indicate that degradation enhancement caused by cytP450 enzymes is involved in the resistance mechanism of barnyardgrass to imazethapyr, and appropriate measures should be taken to manage these populations.

title: Physiological Variables in Pineapples Submitted to the Application of Diuron

description: ABSTRACT Diuron is a widely used herbicide on pineapple cultivations. However, its application is recommended only for the implementation of the crop. The objective of this work was to evaluate the gas exchanges of four pineapple cultivars submitted to the application of the herbicide diuron at their reproductive stage. The experiment was conducted with the IAC Fantástico, Vitória, MD2 and Pérola pineapple cultivars using the active ingredient diuron at a dose of 7.5 mL L-1. Measurements of CO2 assimilation rate, stomatal conductance, transpiration, vapor pressure deficit and water use efficiency were carried out weekly, by the hour, on two plants per cultivar, over a 24 hour period. These determinations were carried out two days before the application of the herbicide and 8, 15, 22, 29 and 36 days after application of the herbicide. Measurement of photochemical efficiency was performed weekly on the same dates and all these determinations were made on the ‘D’ leaf. Measurements of gas exchange were performed with an infrared gas analyzer (IRGA) and of chlorophyll a fluorescence with a fluorometer. The application of diuron reduced the assimilation of CO2 in the pineapple varieties IAC Fantástico, Vitória, MD2 and Pérola, at their reproductive phase, in all CAM metabolism stages. Diuron promoted a temporary reduction of the stomatal conductance and a temporary increase in water use efficiency. The photochemical efficiency of the studied pineapple cultivars was negatively affected by the herbicide diuron, with the recovery of the initial values by cultivar IAC Fantástico.

title: Margnetic recording principles and sound record on wires

description: Abstract We built a magnetic wire recording platform from the scrap of a classic Webster-Chicago recorder. The restored wire recorder uses a motor to control coupled gears and to move trolleys carrying a wire passing through an inductive head. The sound picked up by a microphone is recorded directly within the wire by the inductive head and the same head performs the reading by a reciprocal process. We compared the recorded signal directly from the recording head with the same signal with distortion correction (DC and AC bias) and discussed the signal to noise ratio and distortion of recordings on steel wires.

title: Agro-economic responsiveness of radish associations with cowpea in the presence of different amounts of Calotropis procera, spatial arrangements and agricultural crops

description: ABSTRACT The integration of research emphasizing sustainable development, employment, income generation and food security has been highlighted in the media. The objective of this research was to evaluate the agro-economic responsiveness of radish associations with cowpea in the presence of different amounts of roostertree, spatial arrangements and agricultural crops. The experimental design was a randomized block design with four replications, with treatments arranged in a 4 x 3 factorial scheme, where the first factor consisted of four amounts of C. procera incorporated in the soil (20, 35, 50 and 65 t ha-1 on a dry basis) and the second factor of three spatial arrangements (2:2, 3:3, and 4:4) in two cropping seasons. Radish samples were evaluated for plant height, dry mass of shoots, total and commercial productivity of roots, productivity of scrap roots, and dry mass of roots, while in cowpea, vegetation was assessed for length of green pods, number of pods per square meter, productivity and dry mass of green pods, number of green grains per pod, weight of 100 green grains, and yield and dry mass of green grains. The economic indicators of monetary advantage and modified monetary advantage were used in the evaluation of efficiency. A greater agro-economic responsiveness of the intercropping of radish and cowpea crops was obtained with the incorporation of 56.44 t ha-1 of C. procera. The spatial arrangements of 3:3 and 4:4 had better agronomic and economic responsiveness. The association between radish and cowpea is feasible when the crops are fertilized with C. procera.

title: Effect of Mesotrione and Nicosulfuron Mixtures With or Without Adjuvants

description: ABSTRACT: In Field experiments, a logarithmic sprayer was used to screen the efficacy of 28.5% mixture of nicosulfuron and mesotrione, and the herbicides applied separately. Three adjuvants were also used to assess how they affected the potency of the mixture. The objectives were to test whether a mixture was enhancing or detracting the effect relative to ADM (Additive Dose Model). The test plants were canola and barley. The 28.5% nicosulfuron mixture was acting antagonistic, irrespective of plant species. The antagonistic effect of the nicosulfuron mixture decreased the more developed the plants became; for barley, it almost disappeared 40 days after treatment. For both canola and barley, one adjuvant stood out as being highly effective in decreasing ED50 of the mixture. Antagonism was not alarmingly high, which is found for many herbicides. Results are discussed in relation to the practice of testing mixtures in the literature and the requirements for getting mixture patents.
