title: Immediate effect of a Pilates method exercise session on the co-contraction pattern of the trunk stabilizing muscles in individuals with and without nonspecific chronic low back pain

description: ABSTRACT This study aimed to analyze the immediate effect of a Pilates method exercise session on the co-contraction pattern (agonist/antagonist) of the superficial (iliocostalis lumborum and rectus abdominis) and deep (internal oblique and multifidus) muscles of the trunk in individuals with and without low back pain during local muscle endurance test. Participated in the study adult subjects of both gender, aged between 19 and 59 years, separated into two groups: the group with low back pain (n=9) and the group without low back pain (n=9). Electromyographic signals of the following muscles were collected: internal oblique (IO), multifidus lumborum (MU), iliocostalis lumborum (IL) and rectus abdominis (RA), during maximal voluntary isometric contractions and Biering-Sorensen test, before and after the exercise protocol performance of the Pilates method. The co-contractions between IO/MU right and left (IO/MUr, IO/MUl) and RA/IL right and left (RA/ILr and RA/ILl) were calculated. The co-contraction between IO/MUr, IO/MUl, RA/ILr and RA/ILl was respectively 41.4, 32.4, 56 and 31.2% higher in the group with low back pain (p&lt;0.001 and p=0.003, p=0.004 and p=0.01). The initial condition presented antagonist co-contraction 26.3 and 43.4% higher between IO/MUr (p=0.023, p=0.03). A training session with Pilates method exercises was able to reduce co-contraction between the trunk muscles (in individuals with and without nonspecific low back pain).

title: Economic profitability indicators of minitomatoes organic production in greenhouses

description: ABSTRACT Financial profitability is a factor as important as quantifying production using new technologies. This study was installed to evaluate short and long term financial viability of organic production of cherry tomatoes. Plants were grown in a greenhouse under diverse technological degrees for partial control of micrometeorological elements. The experiment was carried out at the experimental field FEAGRI/UNICAMP in three greenhouses with automated mechanical ventilation systems, evaporative cooling and thermo reflective screen. We cultivated Carolina cultivar in a spacing of 0.5x0.9 m, each plant conducted with two stems, under organic production and fertilization management. The average of production data of treatments {three greenhouses (A= climate-controlled, B= mobile screen and C= fixed screen), two cultivation systems (pots and soil beds) and five biofertilizer doses (0, 50, 100, 150, and 200%)} were evaluated using joint analysis. Thus, the economic indicators {cost benefit ratio (B/C), net present value (NPV), internal rate of return (IRR) and Payback (PV)} were evaluated through revenues and production costs. The best alternative to net monthly cycle profitability (500 m2) was approximately 1 and 1.5 minimum wage with and without particular labor, respectively, associated with the greenhouse of medium technological level, using soil bed cultivation system. The economic viability of the project in long-term interest rates above 3% (a.a) was consistent, but the payback period even with a rate of 1% a.a was high (6.54 years) in financing conditions.

title: INNOVATION AND INTELLECTUAL PROPERTY OF THE 1,2,4-OXADIAZOLES: A TECHNOLOGICAL SURVEY BASED ON PATENT AND PERIODICAL DATABASES

description: 1,2,4-Oxadiazoles are heterocyclic compounds that have a remarkable range of applications. This overview focused on investigating the potential and scientific and technological evolution of these compounds through an analysis of patent databases and scientific papers. Prospecting technology using patent databases is an important tool for mapping technologies or technological areas, allowing the identification of such things as trends and investments. The mapping of 1,2,4-oxadiazoles patents and patent applications was facilitated by using different key word from scientific papers found in the INPI, Esp@cenet, WIPO, LATIPAT databases and in the Web of ScienceTM database. The majority of the patent records related to the researched technology had been filed in the Esp@cenet database. A constant linear growth in the number of records of patents granted could be observed over the years, with a remarkable dominance of patents recorded in the USA (24.7%). In addition, when the search through scientific papers was performed, the USA was also the country that had produced the largest number of publications. On the other hand, Brazil presented only two patent grant records (0.2%) and fifty-four published papers related to the technology being researched. In summary, there is great scientific and technological interest in the 1,2,4-oxadiazoles.

title: SOLID-PHASE EXTRACTION OF PESTICIDE RESIDUES FROM SURFACE WATER USING A LAB-MADE LOWER-RETENTION SORBENT

description: Solid phase extraction (SPE) is one of the main sample preparation techniques. However, the cost of cartridges and the strong retention of hydrophobic compounds in traditional solid phases are limiting factors for their use. This paper describes the application of lab-made SPE cartridges with low retention material as solid phase, Si(PDAS) - poly(dimethyl-co-alkylmethylsiloxane) thermally immobilized on silica, in the determination of pesticide residues in surface water samples. The extraction method of three pesticides: carbendazim, diurom and methyl parathion in water samples was developed, optimized and validated using Si(PDAS) cartridges and HPLC-UV for quantification. The optimized method required a small organic solvent volume for the elution of pesticides from Si(PDAS), producing a concentration factor of 1000 times and allowing limits of detection like those obtained with hyphenated techniques. The validated method for extraction of pesticides in water samples presented: accuracy, with pesticide recoveries between 70-110%; precision, with RSD &lt; 20%, and; high detectability, resulting in LOQ &lt; 0.4 µg L-1 for all compounds. Si(PDAS) cartridges showed similar efficiency to those commercial C18 for the extraction of pesticides in surface water samples, with additional advantages such as ease, simplicity and low cost of preparation, up to six times cheaper than commercial cartridges.

title: Influence of transverse rebars on bond between steel reinforcement and cellular concrete with very low compressive strength

description: Abstract Cellular concrete is a lightweight concrete obtained by aerating agent, which produces air-voids into the mixture. This work deals with bond between cellular concrete and steel rebars. Pull-out tests of 4,2 mm diameter rebars partly immersed into concrete cylinders were made. Concrete unit weight variation and setting of a transverse rebar into the concrete cylinder center constitute the variables of the work. Three types of mixture were prepared: one without aerating agent (with a dry unit weight of 2255 kg/m3), and two with different aerating agent rates (with a dry unit weight equal to 1565 and 1510 kg/m3). The study revealed the large decrease of bond stress between 4,2 diameter rebars and cellular concrete, due to concrete unit weight reduction. Transverse rebar introduced into concrete cylinder center increased the ultimate pull-out force of the test: the gain of bond produced by the transverse rebar grew up when the cellular concrete unit weight had been reduced. Therefore, special anchorages (not exclusively straight), permitting bond improvement between cellular concrete and rebars could be a solution to improve the mechanical performance of cellular concrete.

title: Yield and composition of lavender essential oil grown in substrate

description: ABSTRACT The objective of this research was to evaluate the effect of successive harvesting times and shading on the production of biomass, yield and phytochemical composition of essential oil in leaves and inflorescences of soilless grown Lavandula dentata. Plants were grown in pots filled with sand, inside a polyethylene greenhouse, in a closed system at UFSM. Plants were harvested at 150, 213 and 320 days after planting date (DAP) in winter, spring and summer, respectively. At 150 DAP, a 50% shading screen was installed. The experimental design was a randomized 3x2 factorial in subdivided plots with 36 plants per subplot. Fresh (FM) and dry mass (DM), yield and chemical composition of essential oil in leaves and inflorescences were determined after each harvest date. The essential oil was extracted, using 70 g fresh mass of leaves and of inflorescences, respectively. Identification and quantification of compounds in the essential oil were determined by gas chromatography/mass spectrometry (GC/MS). The FM of inflorescences was higher on plants harvested 213 DAP grown without shading while of leaves it was higher on plants harvested 320 DAP grown without shading. The yield of the essential oil was higher in the leaves of plants harvested 320 DAP grown without shading. Thirty-one compounds were identified and quantified, being the major ones 1.8 cineol, camphor and linalool, without significant difference among treatments. Three consecutive harvests can be made in August (150 DAP), October (213 DAP) and February (320 DAP) without replacing plants.

title: Computed tomography-guided percutaneous biopsy of abdominal lesions: indications, techniques, results, and complications

description: Abstract Objective: To evaluate the performance of computed tomography (CT)-guided percutaneous biopsy of abdominal lesions. Materials and Methods: This retrospective, single-center study evaluated patients submitted to CT-guided percutaneous biopsy of abdominal lesions at a cancer center, between January 2014 and June 2015. The images and patient medical records were reviewed using a standardized data collection form. Results: We included 225 procedures performed in 212 patients, of whom 143 (63.5%) had a prior diagnosis of cancer. Of the 225 lesions biopsied, 88 (39.1%) had a suspected primary origin and 137 (60.9%) were suspected metastatic lesions. Complications occurred in only 14 (6.2%), the most common being self-limited bleeding, which occurred in 12 (85.7%) of the 14. The occurrence of complications was not found to be significantly associated with the lesion location, age of the patient, presence of comorbidities, use of a supplementary technique, vascularization pattern, or proximity of the lesion to large vessels. The pathology findings were sufficient for making the diagnosis in 202 cases (89.8%), and the diagnosis was consistent with the clinical suspicion in 132 (58.6%). Conclusion: The procedure demonstrated a high (approximately 90%) rate of providing a sufficient sample for the diagnosis and a low complication rate, the most common complication being self-limiting bleeding.

title: Computed tomography-guided preoperative localization of musculoskeletal lesions using the ROLL technique

description: Abstract Objective: To describe the preoperative localization of musculoskeletal lesions with the radioguided occult lesion localization (ROLL) technique. Materials and Methods: In all cases, computed tomography-guided injection of technetium-99m sulfur colloid was performed, directly into or near the suspicious lesion, up to 36 hours before the surgical procedure. Lesions were detected intraoperatively with a gamma probe. Results: We report the cases of six patients submitted to radioguided surgery, including three patients with bone lesions suspicious for metastasis, two patients suspected of recurrent sarcoma, and one patient with no previous diagnosis who had a nodular lesion on the left leg. Patients tolerated the procedure well, and no complications were associated with the puncture. All marked lesions were easily identified intraoperatively and were excised with clear margins. Conclusion: The ROLL technique was effective in the intraoperative localization of occult musculoskeletal lesions, demonstrating that it is a feasible and promising technique for the surgical exploration of selected cases.

title: EVALUATION OF BIODIESEL CHARACTERISTICS OF ALTERNATIVE SOURCES SUBMITTED TO DIFFERENTIAL STORAGE CONDITIONS

description: Biodiesel is an alternative fuel obtained from different biomass sources and processes. Nowadays, this biofuel has gained importance due to environmental concerns and rising energy demand. In the biodiesel production chain, stability is a critical issue, as it is linked to the maintenance of its original properties. This work performed a study evaluating the influence of storage conditions on the quality aspects of biodiesel. Thus, different samples of biodiesel obtained from soybean and frying oils were produced and placed in containers made by plastic, glass and tin, and stored in presence or absence of an oxidative atmosphere, moisture and light. These samples were analyzed to evaluate the ester content, acidity, iodine value, kinematic viscosity and oxidative stability. The characterization with GC-MS and GC/FID were done aiming to determine the chemical composition. Blends with frying biodiesel into soybean biodiesel have also been produced in concentrations ranging from 1%, 5% and 10% (m/m) in order to evaluate the mixing effect. In the initial storage time, all tested parameters were in accordance to the legislation. Distinct behaviors were identified for each sample according to the container type, being the glass the most effective of them in maintenance of biodiesel characteristics.
