title: COORDINATION MECHANISMS OF COLLABORATIVE R&D PROJECTS IN SMALL AND MEDIUM ENTERPRISES

description: ABSTRACT Purpose: To analyze how small and medium enterprises (SMEs) coordinate collaborative research and development (R&D) projects through an open innovation strategy. Originality/value: This research was motivated by a theoretical gap in the management of collaborative R&D projects in open innovation strategies. The originality of the paper is to advance the understanding of coordination mechanisms that SMEs can use to manage open innovation and obtain more effective results. Design/methodology/approach: The research followed a qualitative approach, through three case studies of collaborative projects. Data were collected by means of in-depth interviews with eleven managers directly involved in collaborative R&D projects. Findings: Results demonstrate that the use of coordination mechanisms depends on the applicability of each project’s results, i.e., the higher the chances of a certain R&D project becoming a real product, the higher the importance given to the coordination mechanisms. On the cases observed, the coordination mechanisms were defined by the enterprise, not by external partners. In addition, it was observed that open innovation projects that the enterprise seeks for external knowledge to complement internal resources (outside-in) were considered more important than transferring internal knowledge to external partners (inside-out). The paper contributes to organizational theory by highlighting the relation between the characteristics of collaborative R&D projects and the coordination mechanisms used. Regarding the managerial contribution, results serve as a guide for entrepreneurs and managers of SMEs interested in coordinating collaborative projects based on open innovation processes.

title: Syntheses, Experimental and Theoretical Studies on Absorption/Emission Properties of Pyrazoline-Containing Aryl/Methoxynaphthyl Substituents

description: 5-Aryl-3-(2-methoxynaphthalen-6-yl)-1-phenylpyrazoline derivatives were synthesized starting from (E)-1-(3-aryl)-(2-methoxynaphthalen-6-yl)-prop-2-en-1-one and phenylhydrazine. The compounds were characterized by 1H and 13C nuclear magnetic resonance (NMR), elemental analyses and mass spectrometry. Some compounds showed promising luminescence properties in solution and in solid state; the absorption and emission characteristics were measured and the fluorescence quantum yield of two of the derivatives [4,5-dihydro-3-(2-methoxynaphthalen-6-yl)-5-(3,4,5-trimethoxyphenyl)-1-phenyl-1 H -pyrazoline and 5-(4-chlorophenyl)-4,5-dihydro-3-(2-methoxynaphthalen-6-yl)-1-phenyl-1 H -pyrazoline] were found to have excellent values compared to rhodamine B standard. Theoretical calculations at time-dependent density functional theory (TD-DFT) level are in agreement with the experimental measurements and are helpful to explain the electronic behavior.

title: TILLAGE INTERFERENCE IN THE QUALITY OF PEANUT MECHANIZED HARVEST

description: ABSTRACT In Brazil, a large portion of peanut production is found under conventional soil preparation. Due to the fact that there is a lack in studies related to the cultivation of peanuts in conservationists soil preparation, mainly in the field of losses and mechanized harvesting. Thus, it was aimed to assess the quality of digging and gathering operation of peanut, based on losses, using statistical process control techniques in two tillages. The sowing was carried out under conventional and conservationist preparation, revolving only the sowing line. Losses were evaluated in the digging and gathering operation, being that in the gathering it was evaluated the harvest losses in three displacement speeds (4, 6 and 8 km h-1) in two tillages. The quality of the process was affected by the soil preparation based on the visible and invisible losses, respectively. Regarding the gathering, the conservationist preparation, it was unstable in all indicators, whereas in the conventional preparation it was noticed reduction of the variability for all the displacement speeds. The peanut sowing under conservationist preparation provided a better quality digging. In contrast, the gathering of pods in areas under conventional tillage showed a better quality of the operation.

title: Location and hemodynamic role of perforating veins independent of saphenous veins

description: Abstract Background The perforating veins of the lower limbs (LL) have valves that enable the blood flow to be directed from the superficial vein system to the deep vein system and they may or may not be connected to the saphenous vein system. Objectives To use vascular ultrasonography (VUS) to identify the frequency, location, caliber, and hemodynamic role of perforating veins that do not connect to saphenous veins, during preoperative mapping of LL varicose veins. Methods A cross-sectional study was conducted using VUS in women to study the frequency, location, distance from the sole of the foot, and hemodynamic role of perforating veins. Results The frequencies of perforating veins independent of the saphenous veins were 92.6%, 5.1%, and 2.3%, in the leg, thigh, and knee, respectively, and 25.2% of them were incompetent while 72.3% were drainage veins. The mean diameters of perforating veins were 2.9 mm, 3.5 mm, and 3.7 mm, in the leg, thigh, and knee, respectively. Perforating veins were located at mean distances of 23.8 cm, 43.6 cm, and 59.4 cm above the sole of the foot in the leg, knee, and thigh, respectively. Perforating veins with reflux had a mean caliber of 3.5 mm, irrespective of location. Conclusions Perforating veins independent of the saphenous veins are most frequent in the leg, draining reflux from tributary veins. Irrespective of location, perforating veins with reflux had mean caliber of 3.5 mm.

title: Permanent treatment suture for the treatment of congenital nerve palsy of III nerve

description: Abstract Paralysis of the third cranial nerve represents the most complex and challenging paralytic squint. The cases of complete III nerve paralysis encourages the use of certain strabismus surgery techniques in order to keep eye in primary position of gaze. However, the therapeutic possibilities are limited and complex and the surgical treatment tends to hypocorrection and frequent recurrences in the long term. Complete and congenital involvement of the third cranial nerve requires surgeries for exotropia, hypotropia and ptosis. Among the surgical techniques already described, we choose a modification of the surgical technique of recession-resection, which occurred in a single surgical time, being suffice to achieve aesthetic objective. This paper reports the positive result of the maintenance of caruncle traction suture as surgical treatment of congenital III nerve paralysis.

title: Immune response and biochemistry of calves immunized with rMSP1a ( Anaplasma marginale) using carbon nanotubes as carrier molecules

description: Abstract Vaccination against Anaplasma marginale has been considered an important control strategy for bovine anaplasmosis. Recently, mice immunized with rMSP1 a linked to carbon nanotubes (MWNT) showed significant immune responses, generating a new possibility for use of an inactivated vaccine. The objective of this study was to investigate the cellular and humoral responses in calves immunized with MWNT+rMSP1a , associated with inactivated vaccine of A. marginale produced in vitro, and evaluate the toxic effects of the MWNT on renal and hepatic function. rMSP1a was covalently linked to MWNT. Inactivated vaccine (AmUFMG2) was produced by cultivating A. marginale in IDE8 cells. Twenty-four Holstein calves were divided (four groups) and immunized subcutaneously with PBS and non-carboxylated MWNT (control, G1), AmUFMG2 (G2), MWNT+rMSP1a (G3), and AmUFMG2 with MWNT+rMSP1a (G4). Blood samples were collected for total leukocyte counts, biochemical profiling and evaluation of the cellular and humoral response. Immunization with MWNT+rMSP1a induced increase in the total number of leukocytes, NK cells, in the lymphocyte populations and higher levels of antibodies compared to calves immunized only with AmUFMG2. Furthermore, MWNT did not induce changes in the biochemical profile. These data indicate that MWNT+rMSP1a were able to induce the immune responses more efficiently than AmUFMG2 alone, without generating toxicity.

title: NO-VALUE GENERATION? SUCCESS IS AN 'EXACT SCIENCE' THAT EVERYONE CAN LEARN!

description: ABSTRACT Purpose: The general objective is to critically analyze the ideologies and constructions of management ideology in the Internet blog called Geração de Valor (Generation of Value), behind the discourse of success. Originality/value: The pop-management phenomenon has been widespread in the Brazilian context. It leads individuals to look for formulas of excel and achieve success as entrepreneurs. One of the disseminators of this ideology has been Geração de Valor. This article innovates when dealing with thematic without prima donna behaviors or fanciful romanticism. Design/methodology/approach: This article aims to analyze texts available on Geração de Valor through critical discourse analysis (CDA). Findings: We conclude that the voice of the businessman and blogger Flávio Augusto da Silva is nothing more than one of several voices, including in administration, that seek to defend the cult of personal victory and disdain for the collectivist practices of social organization. This kind of analysis is still scarce in this field of study, as they require enriched readings of the text in terms of context and intertextuality. Critical analyses contradict hegemonic visions and sharpen the reader's critical sense. Also, they are useful in highlighting the cult following that Administration has been receiving by the media.

title: CLIMATE CHANGE AND RURAL WORKERS THERMAL COMFORT: HISTORICAL AND FUTURE IMPACTS

description: Abstract The aim of the present research was to propose a bioclimatic mapping to classify the thermal comfort and discomfort of rural workers within the state of Minas Gerais, considering historical and future scenarios. Monthly historical series (1976-2014) of minimum, mean and maximum temperature-humidity index (THI), determined through the values of air temperature (minimum, mean and maximum) and relative humidity from 48 weather stations located in the state of Minas Gerais were used to analyze the trends through Mann-Kendall and linear regression assays. The bioclimatic mapping of human comfort, obtained via geostatistical analysis, was developed as a function of the minimum, medium and maximum THI for the historical period (1976-2014) and future scenario (2024). Results indicate an overall trend of increasing in thermal discomfort conditions throughout the mesoregions of the state of Minas Gerais during the weather seasons, being more incisive in summer and spring.

title: True or false coral snake: is it worth the risk? A Micrurus corallinus case report

description: Abstract Background Bites provoked by the genus Micrurus represent less than 1% of snakebite cases notified in Brazil, a tiny fraction compared with other genus such as Bothrops and Crotalus, which together represent almost 80% of accidents. In addition to their less aggressive behavior, habits and morphology of coral snakes are determinant factors for such low incidence of accidents. Although Micrurus bites are rare, victims must be rescued and hospitalized in a short period of time, because this type of envenoming may evolve to a progressive muscle weakness and acute respiratory failure. Case Presentation We report an accident caused by Micrurus corallinus involving a 28-year-old Caucasian sailor man bitten on the hand. The accident occurred in a recreational camp because people believed the snake was not venomous. The victim presented neurological symptoms 2 h after the accident and was taken to the hospital, where he received antielapidic serum 10 h after the bite. After the antivenom treatment, the patient presented clinical evolution without complications and was discharged 4 days later. Conclusions We reinforce that it is essential to have a health care structure suitable for the treatment of snakebite. Besides, the manipulation of these animals should only be carried out by a team of well-equipped and trained professionals, and even so with special attention.
