The loss of biodiversity and ecosystem services disturbance will result in serious ecological and socioeconomic consequences. How can people be prepared to be more efficient in preserving ecosystems, its services and resources? The Messalo Wilderness Area (MWA) is an area lacking a bottom-up approach for the design of a management plan. This research intended to develop a strategy to gather people’s views to begin a human wellbeing assessment for the area, for which a Digital Questionnaire (DQ) was developed and tested. The specific objectives were to 1) verify the dispersion/distribution of people and elephants;2) study the natural resources used by the inhabitants;3) locate the areas from where the most important natural resources are extracted and where conflict between humans and animals occur;4) propose a Management Plan (MP) capable of mitigating the human-animals conflict, promoting the conservation of elephants and, consequently, of other types of biodiversity, thus working towards a better socio-economical development of the area. The elements gathered in the consulted references were used to design several maps and cartographic figures shown in this article, using the Map Window software. These maps describe: fresh water distribution, habitat distribution, population dispersal and main road connections, crop fields distribution and main exploitation spots of the different resources, orography and topography. The results from the DQ analysis helped to gather indicators to the human wellbeing assessment. The information gathered in the literature and by inquiry was effective in confirming the high dependency of local people on land and sea resources, as well as the conflicts between people and wild animals, such as elephants and African wild dogs, and the reasons for those conflicts. The DQ is effective in gathering people’s opinions and it constitutes an important tool in a bottom-up approach to the design of a management plan as to the design of the MP for

Channel Flows in Plate Heat Exchangers with the Aid of Particle Tracking Velocimetry

引用

Open Journal of Fluid Dynamics 2024年第3期14卷 163-183页

Channel flows of Plate Heat Exchangers (PHEs) were assessed by experiments with three different chevron angle arrangements in turbulent regime. Two chevron angles were selected to assess low and high pressure drop channels, besides a third mixed configuration as to achieve in-between results regarding hydraulic performance. Friction factor correlations were provided with the channel Reynolds number ranging from 1175 to 8325. Two-dimensional (2D) mean velocity field was obtained by Particle Tracking Velocimetry (PTV) with Reynolds number equal to 3450. To the best of our knowledge, this is the first experimental study that quantified the complete 2D velocity field of a typical PHE channel. This value allowed comparison with literature results of Plate and Shell Heat Exchanger (PSHE) channels with the same Reynolds number. PSHE mean velocity field is highly heterogeneous as compared to the one obtained for PHE channels. Peak velocity magnitude in the PSHE center is 50% higher than its bulk velocity, whereas this value is only 15% higher in the PHE center. Pressure drop in PHE mixed channels cannot be approximated by averaging chevron angles: furrow flow prevailed in the specified conditions. The axial velocity is asymmetric regarding the vertical plane. Smooth streamlines prevail in the channel inlet. Recirculation zones at the channel exit affect pipe flow in the manifold outlet with swirling flow structures. The necessary length to obtain fully developed pipe flow at the channel outlet was estimated. Significant velocity components occur in the distribution areas and can limit the heat exchanger performance. The results reported herein are essential to understand how the PHE channel geometry affects the velocity field and, therefore, local heat transfer and dissipation processes.

Seeds from Tabebuia roseo-alba lose viability very fast. Moreover, the seed germination rate is very low, reaching approximately 40%. This study aimed at the in vitro induction of embryogenic callus. This technology allows subsequent plant regeneration as an alternative for the production of T. roseo-alba seedlings. Seeds were germinated in vitro and after 20 days, cotyledonary leaves, hypocotyls and root segments excised from these seedlings were used as explants. They were inoculated on MS medium supplemented with sucrose （30 g/L）, agar （5.0 g/L） and different auxins. The effect of 2,4-D, picloram and NAA at concentrations 0.0, 0.5, 1.0, 2.0 and 4.0 mg/L was evaluated. For the analysis of callus with embryogenic characteristics, ultra-structural study by scanning electron microscopy and cytochemical test with carmine were performed. The results showed that the culture medium supplemented with 4 mg/L NAA presented induction of callus with embryogenic characteristics in all explants used, with cotyledonary leaves showing the highest percentage （70% of explants with embryogenic characteristics）. The use of 2, 4-D and picloram was efficient for callus formation in different explants, but no embryogenic characteristics were observed. From the ultra-structural analysis of callus with embryogenic characteristics, it was found that cells from different explant sources had isodiametric format. This format is similar to somatic embryos in globular stage. The cytochemical analysis confirmed the presence of pro-embryogenic cells in callus mass. Callus induced from cotyledonary leaves presented 46% positive reaction to carmine acetic.

Introduction: The diagnosis of small renal masses and the endophytic tumor approach have become challenging. This study aims to describe exclusively robot-assisted surgery as an alternative nephron-sparing approach for renal intraparenchymal tumors. Patients and Methods: We retrospectively analyzed all patients with completely endophytic tumors undergoing robot-assisted partial nephrectomy, treated under the Da Vinci System®, aided by intraoperative ultrasound. The patients’ demographic characteristics, perioperative and oncological outcomes were assessed. Results: From a total of 13 partial nephrectomies performed between 06/2010 and 10/2021, all patients underwent nephrotomy. The patients’ mean age was 52 years and the tumor measured mean 2.6 cm. Warm ischemia time was 24 minutes and histopathological analysis revealed that 12 patients had renal cell carcinoma. In a mean 36-month follow-up, no significant renal function alterations were found and no local or systemic recurrences occurred. Conclusion: Robot-assisted access is a safe and effective option for the nephron-sparing technique in completely intraparenchymal renal tumors.

The main objective of this paper is to analyse the vertical loads effects applied on the pavement, considering the variation of tire pressure, from a truck＇s front suspension. For the measurements, a durability test track located in Brazil has been used. The tire pressure was increased by l0 psi from 90 psi to 130 psi with a constant load of 6 t on the front suspension, the maximum allowed load for front axle according to Brazilian legislation. By applying relative damage concept, it is possible to conclude that the variation on the tire pressure will not affect significantly the load applied on the pavement. However, it is recommended to repeat the same methodology in order to analyse the influence on the variation of the other quarter car model variants.

Rupture of the Achilles tendon is one of the most frequent tendon injuries in humans. However, there is no standard surgical technique thus far to reproduce complete rupture of this tendon in rats. Surgical procedures were performed in Wistar rats under light microscopy, with posterior longitudinal incision and preservation of the plantaris tendon. The animals were sacrificed on 2nd and 8th postoperative week and we used hematoxilin and eosin, picrosirius-red and Weigert’s resorcin-fuchsin to observe general tendon healing. The mean operative time was one minute and 24 seconds. Histological studies showed cellular proliferation and fibrillogenesis at two weeks, with decreased amounts of cellularity and elastic fibers at the 8th week, besides changes in structural organization of collagen fibers. The complete Achilles tenotomy in rats, was improved under light microscopy and sparing the plantaris tendon. This surgical technique was simple and quick, showed signs of normal healing process, could be easily reproducible, and triggered translational researches in this area.

Achilles tendon rupture is one of the most frequent tendon injuries. The aim of this experimental study was to evaluate the effect of a non-steroidal anti-inflammatory drug (NSAID) and of aerobic exercise, in an isolated fashion and combined, on cell proliferation and on the biomechanical aspects of the Achilles tendon during healing process after a complete tenotomy in 156 male Wistar rats. Half of the animals received an intra-muscular injection of tenoxicam for 7 days and exercise was initiated on the 8th day for half the animals of each group. Animals were sacrificed at 1, 2, 4 and 8 weeks after the tenotomy and cell proliferation was evaluated by immunohistochemistry for PCNA, biomechanical evaluation was performed with ultimate load and gait cycle analysis was also carried out. Animals were divided into four treatment groups: A) no NSAID and no exercise (control group);B) NSAID plus exercise;C) no NSAID, with exercise;D) NSAID and no exercise. We used the test of two-way analysis of variance with equal cells number, Kruskal-Wallis test and also, Bonferroni method, in the R Project program 3.5.0. The highest intensity of PCNA immunostaining was found at 2 weeks in all groups except for group A (control) that had the highest intensity at 1 week. Animals submitted to exercise had significantly higher (P = 0.02) ultimate loads when compared to animals that were not submitted to exercise at 8 weeks after injury. The animals that received NSAID presented with a more stable gait cycle than the animals that did not receive NSAID. Aerobic exercise, initiated early after a complete Achilles tendon tenotomy, was beneficial to the biomechanical aspects of the tendon that occur during tendon regeneration and the combined use of NSAID improved the gait’s characteristics which could be protective against re-ruptures.
