The acupuncture meridians represent the flow of corporal energy which contains the acupuncture points. Laser acupuncture is a form of acupuncture stimulation by the use of laser. Thermographic images represent the propagation of heat in micro-environmental systems. The objective of this study was to investigate the use of thermographic images to document the changes on the small intestine meridian (S.I.M.) when submitted to laser acupuncture. Another important issue regards to the analysis of the flow direction if it is upward when stimulated by acupuncture points. For the execution of this work, a laser acupuncture pen was used in points of the meridian in the S.I.M. Two healthy male volunteers were selected (18 and 60years old, respectively), and doses of 576,92J/cm

The microstructure of a 26.6% chromium white iron was characterized in a previous study. An observation within this study confirms the literature that the eutectic (Fe,Cr)7C3 carbide phase within high chromium content ferrous alloys always contains crystalline faults regardless of heat treatment. A kinematical model is put forwards to explain how mechanical stacking faults occur within (Fe,Cr)7C3 carbide. The kinematical model was compared to the findings obtained from a high resolution transmission electron microscope. © 2010 Elsevier B.V. All rights reserved.

In this study, ozonation of raw textile wastewater was conducted in a pilot-scale plant and the efficiency of this treatment was evaluated based on the parameters color removal and soluble organic matter measured as chemical oxygen demand (COD), at two pH values (9.1 and 3.0). Identification of intermediate and final degradation products of ozone pre-treatment, as well as the evaluation of the final ecotoxicity (Lumistox test) of pre-treated wastewater, was also carried out. After 4 h of ozone treatment with wastewater recirculation (flow rate of 0.45 m3 h-1) the average efficiencies for color removal were 67.5% (pH 9.1) and 40.6% (pH 3.0), while COD reduction was 25.5% (pH 9.1) and 18.7% (pH 3.0) for an ozone production capacity of 20 g h-1. Furthermore, ozonation enhances the biodegradability of textile wastewater (BOD5/COD ratios) by a factor of up to 6.8-fold. A GC-MS analysis of pre-treated textile wastewater showed that some products were present at the end of the pre-treatment time. In spite of this fact, the bacterial luminescence inhibition test (Lumistox test) showed a significant toxicity reduction on comparing the raw and treated textile wastewater. In conclusion, pre-ozonation of textile wastewater is an important step in terms of improving wastewater biodegradability, as well as reducing acute ecotoxicity, which should be removed completely through sequential biological treatment. © 2009.

The pollination ecology of the blackberry (Rubus sp.) was studied by means of determining its reproductive system, the analysis of flower's nectar production. Sampling the insects that visited the blackberry flower in a cultivated area and analyzing the pollination behavior. The experiments were carried out in an area of blackberry crop, in December of 2005 in the city of Timbó (SC), Southern Brazil. The highest fruit set (48.3% ± 3,2) occurred in the free pollination (natural) treatment where insects were not excluded. The occurrence of selfing was verified, however with lower fruit set (12.2% ± 4,9). Anemophily was not observed in the species. The nectar evaluation in Rubus sp. resulted in values compatible with the melittophily syndrome. Bees (Hymenoptera) were the main floral visitors collected and observed on the flowers of Rubus sp., representing 97% of the individuals. They initiate the foraging activity at 8 a.m., with a peak activity at 12 a.m. and declining until 4 p.m. In the survey were sampled 1.360 bees, belonging to four families and 13 species. Halictidae was the family with highest amount of species (N = 7) and Apidae most abundant (1.288 individuals) in the survey. Apidae was mainly represented by Apis mellifera, which is an exotic species, whose sample was of 1.246 individuals. The data of the abundance and the observation of its behavior, pointed A. mellifera as the main pollinator of Rubus sp., in the studied area, but also confirms that the other native species of bees, participate in the pollination process of Rubus sp.

Objective: To compare bone mineral density (BMD) and body composition (BC) of college students with different lifestyles. Methods: Transversal study with 85 students of Medicine (MED) and Physical Education (PE) at the Universidade Regional de Blumenau, SC, Brazil. The anthropometric, socio-demographic, clinical, and lifestyle variables were obtained through densitometric anamnesis and densitometric variables by dual-energy X-ray (DXA). The statistical tests used were: Student's t-test, Chi-square test, and logistic regression. Results: PE male students showed a higher amount of lean body mass (79.5 ± 5.9 vs. 75.1 ± 5.3; p = 0.03) and a lower amount of body fat (16.7 ± 6.1 vs. 21.6 ± 5.6; p = 0.02) and PE female students showed a higher amount of lean body mass (68.2 ± 5.5 vs. 65.3 ± 5.5; p = 0.05). The BMD of the neck of femur (NOF), total femur (TF), and total body (TB) was higher in PE students of both genders. PE students practiced more physical activities than MED students. Low bone mass (LBM) was more frequent in MED students (34.9% vs. 4.7%; p = 0.001), provided that the risk of a MED student to show LBM was nine times higher for lumbar spine (LS), five times for NOF, eight times for TF, and seven times for TB. Conclusion: BC and BMD were different among the students; MED students have shown a higher risk of having LBM, and PE students practiced more physical activities. © 2012 Elsevier Editora Ltda.

A drying kiln schedules is a prescript, for every each species and thickness, of environmental conditions inside drying chamber, which equilibrate the drying rates and formation defects. Among the methodologies of drying kiln schedules elaboration, those based on application of empiric equations having the specific gravity as independent variable and those based on evaluation of small pieces during drastic drying are highlighted. The objective of this research was to apply and to compare these two methodologies for drying kiln schedules elaboration for marupá, pará-pará and virola. The parameters for drying schedules elaboration were experimentally obtained on 32, 32 and 29 pieces of marupá, pará-pará and virola, respectively. Comparing the drying potential obtained by different methods, it was different at all steps for all species, and the dry bulb temperature is different until the moisture content of 30% for marupá and virola and under this point for pará-pará.

One of the main objectives of the Regional University of Blumenau (FURB) is the interdisciplinary education. The discipline 'University, Science and Research' should educate in the interdisciplinary to students of the course the computational sciences. The article discusses the Epistemology of Cognitive Sciences. The Epistemology renewed inserts in your arsenal of ideas individual and social aspects, but the regulatory pretensions, already mentioned, are not overlooked. Thus there is a change in focus of epistemic assessment because worries now, backed by the cognitive agent. A belief must be justified when it is produced by one or more processes that usually produce more truth than falsehood. © 2015 IEEE.

This work aims to develop an Expert system (ES), which assists the user to have a control against floods and landslides in the watershed of the Itajaí-Açu River region. In Blumenau, mainly, the occurrence of this kind of disaster is common and the people need to have means to always be informed and to know how to act in this kind of situation. The Operation Center of Alert System Itajaí Basin (CEOPS) is an example of it, because it is a mean of very useful information when some disaster occurs. In order to provide an extra alternative about these questions, it was developed a system where the user can simulate situations, working as a tool for forecasting floods and landslides. The knowledge base was created with information provided by CEOPS and existing scientific works of the study area. It was developed in the Java language integrated with the Java Embedded Object-Oriented Production Systems (JEOPS) tool, responsible for the construction of the knowledge base and the rules inference. © 2015 IEEE.

The rhizomes of Zingiber officinale Roscoe (ginger) are widely used for their medicinal and flavoring properties, whereas the influence of root symbionts on their growth is poorly understood. In this study, the effects of phosphate fertilization and inoculation with a mixture of arbuscular mycorrhizal fungi (AMF) (isolates Glomus clarum RGS101A, Entrophospora colombiana SCT115A and Acaulospora koskei SPL102A) on survival, growth and development of micropropagated ginger were investigated. After transplanting to post vitro conditions, the ginger microplants were subjected to the following treatments: a) AMF mixture, b) P addition (25 mg kg-1), c) AMF + P, and d) non-mycorrhizal control without P addition. After eight months of growth, survival ranged from 86 to 100 % in the AMF and AMF+P treatments versus 71 % survival in control and P treatments. In the AMF, P and AMF+P treatments, the shoot, root and rhizome biomass production were significantly larger than in the control plants. In the nonmycorrhizal control plants the leaf number, leaf area, number of shoots/plants, and shoot length were significantly lower than in the AMF, P and AMF+P treatments. Root colonization ranged from 81 to 93 % and was not affected by P application. The data confirmed the response of several growth variables of micropropagated ginger to mycorrhizal colonization and P addition.

Production of arbuscular mycorrhizal fungi (AMF) inoculum using the on-farm method is an alternative to stimulate the use of microbial inoculant in plant production systems and to reduce the cost associated with purchase of this product. The goal of this study was to evaluate the potential of residues from the forestry industry, pine bark (CP) and pulp sludge (LC), as components of the substrate used to produce on-farm mycorrhizal inoculum. Sorghum plants pre-colonized with the AMFs Claroideoglomus etunicatum RJN101A and Dentiscutata heterogama PNB102A were established in a greenhouse for three months in a substrate of sand:expanded clay:soil (2:2:1). After this period, plants were transplanted to 20 L plastic bags containing a substrate with CP or LC mixed with carbonized rice hulls + soil (1:1:1). The experiment followed a 2 x 2 factorial arrangement, of two fungal isolates and two residues, with five replicates, in a completely randomized design. Plants were grown outdoors for three months and then the substrate was analyzed for AMF spore numbers, mycorrhizal colonization of the host plant, and inoculum potential by the MPN (most probable number) method. The substrate of each bag was divided into three layers (upper, middle, and lower portion) and only the number of spores was analyzed separately for each layer. The type of residue did not affect the number of spores of either AMF, but this number decreased from the upper to the lower layer within each experimental unit. D. heterogama tended to produce more spores than C. etunicatum. Sorghum mycorrhizal colonization by AMF was significantly greater in the LC residue than in the CP residue. The number of AMF infective propagules also tended to be higher in LC (22 to 28 propagules cm-3 substrate) than in CP (2 to 7 propagules cm-3 substrate). The LC residue showed potential for use as a component of the substrate in mycorrhizal inoculum production systems using the on-farm method. © 2014 R. Bras. Ci. Solo. All rights reserved.
