CALIBRAÇÃO DE UM EQUIPAMENTO TDR EM CONDIÇÕES DE CAMPO Rosangela Villwock; Maria Hermínia Ferreira Tavares; Márcio Antônio Vilas BoasCentro de Ciências Exatas e Tecnológicas, Universidade Estadual do Oeste do Paraná, Cascavel , PR, mhstavar@certto.com.br 1 RESUMO A utilização da Reflectometria no Domínio do Tempo (TDR) tornou-se um método muito bem aceito nas avaliações de teores de água no solo. Todavia, para utilização do equipamento há a necessidade de calibrá-lo para que se obtenha valores acurados de umidade volumétrica, devendo-se sempre respeitar as peculiaridades de cada solo para que o processo de calibração ocorra de forma correta. O objetivo deste trabalho foi calibrar o equipamento TDR em condições de campo, especificamente para um Latossolo Vermelho distroférrico, localizado no Núcleo Experimental de Engenharia Agrícola, Universidade Estadual do Oeste do Paraná, Campus de Cascavel. O modelo polinomial cúbico foi o que melhor se ajustou aos dados para a calibração do equipamento. UNITERMOS: constante dielétrica aparente, modelo polinomial cúbico, umidade do solo. VILLWOCK, R.; TAVARES, M. H. F.; VILLAS BOAS, M. A.TDR EQUIPMENT CALIBRATION IN FIELD CONDITIONS 2 ABSTRACT The use of Time Domain Reflectometry (TDR) has become a very well accepted method to evaluate soil water content. However, for the equipment utilization there is the need to calibrate it to obtain accurate values of volumetric soil water content, always respecting the soil characteristics. The objective of this research was to calibrate the TDR equipment in field conditions, specifically for a Rhodic Hapludox, at the UNIOESTE Experimental Station of Agricultural Engineering, in the campus of Cascavel, State of Parana. The cubic polynomial model was the model that best adjusted the data for the calibration of the equipment. KEYWORDS: apparent dielectric constant, cubic polynomial model, soil moisture.

A vantagem do presente sistema é que o mesmo dispensa a utilização de uma válvula reguladora do nível de água no interior do tanque medidor na avaliação do processo de perda d'água para a atmosfera, e considerando que o tanque medidor proposto é também um pluviômetro, infere-se que o sistema em estudo permite a coleta de dados para dias com chuvas leves (intensidade com ordem de grandeza da evapotranspiração), melhorando, portanto, a confiabilidade das leituras obtidas com o tanque classe A padrão empregado largamente no manejo de água das culturas. UNITERMOS: tanque classe A, evapotranspiração, manejo da irrigação. VILLA NOVA, N.A.; SENTELHAS, P.C.; PEREIRA, A.B.EVAPO-PLUVIOMETER: A NEW SYSTEM FOR MEASURING THE CLASS A PAN EVAPORATION 2 ABSTRACT A new system of measurements coupled to a standard class A pan that may balance evaporations of a water free surface exposed to the local climatic conditions and to rainfall is proposed. The advantage of the current system is that it deals with a system that allows data collection on days light rainfall days (i.e. when rainfall intensities correspond to evapotranspiration), once it does not require a valve for water level regulation inside the measurer tank to assess water loss into the atmosphere, and because this proposed measurer tank is also a pluviometer. Thus, the reliability of the readings obtained by the conventional class A pan within water management on crops is improved. KEYWORDS: class A pan, evapotranspiration, irrigation management.

POTASSIUM DOSES APPLIED BY FERTIRRIGATION USING SUPERFICIAL AND SUBSUPERFICIAL IRRIGATION IN NET MELON IN GREENHOUSE 2 ABSTRACT The purpose of this research was to study the effects of three doses of potassium application, under drip irrigation in two soil profile layers, on melon productivity (Cucumis melo L.). The experiment was carried out in a kind of chapel-shaped greenhouse, in Limoeiro do Norte, CE, Brazil, from April to August 2002. Bonus 2 hybrid young plants were transplanted, separated every 0.5 x 1.0m and vertically supported on 2.0 m high racks. The treatments were a combination of doses of potassium (40; 120 and 200 kg ha-1) and the following nutrient application depths: 0.0 m (surface) and 0.20 m (subsurface). The experimental design was made in randomized blocks with factorial arrangement 2 x 3 and 4 replications. The evaluated variables were: number of fruits, average fruit weight, total productivity and commercial productivity. The potassium fertilizer application on subsurface by irrigation did not provide significant differences, in comparison to a surface application; the potassium level increase from 40 kg ha-1 to 120 kg ha-1 and 200 kg ha-1 did not cause significant changes in the analyzed variables. Keywords: Cucumis melo L, greenhouse, drip irrigation.

Published: October 2018

Thermodynamic analysis of the effect of silicon on the solubility of oxygen in Fe – Co – Cr melts has been carried out at 1873 K. Silicon has a sufficiently high deoxidizing ability in Fe – Co – Cr melts. Silicon at low contents practically does not affect the concentration of oxygen in the melt, which is determined by the chromium content. With a higher content of silicon after changing the mechanism of interaction process of chromium and silicon with oxygen, when silicon already determines the solubility of oxygen in the melt, the oxygen concentration decreases.

Background: The current study aims to compare the efficacy of Bishop score assessment and transvaginal ultrasonographic measurement of the cervical length in prediction of the outcome of labor induction in post-term pregnancy.Methods: A comparative Prospective observational study conducted in Department of Obstetrics and Gynecology, Kom Ombo central hospital from January 2017 to October 2017. Pregnant women were classified into two groups of Bishop Score Group (1): ladies with (Bishop Score <5) = unfavorable cervix and Group (2): those with (Bishop Score >5) = favorable cervix. Also, they were classified into two groups of cervical lengths: Group (1): women with (cervical length <25mm, shorter cervix) and Group (2): those with (cervical length ≥25 mm, longer cervix). The Primary outcome was Bishop score by digital examination and Cervical length by TVS.Results: The study group was 100 women. Regarding sonographic assessment, 44 patients had cervical length <25 mm and the mean cervical length for the whole study group was 25.19±8.16 mm. Successful induction was achieved in 78 patients (78%), while CS was done in 22 patients due to failed induction. No difference between both groups regarding the parity (p=0.063). When comparing women with successful VD versus those delivered by CS, we found significantly higher Bishop score in the first group 5.12 ± 1.93 vs 3.89 ± 1.71 in the second group (p=0.002). Additionally, VD group had significantly shorter cervix than CS group (22.31 ±7.14 vs. 35.37± 5.80 mm, p=0.007). The Bishop score showed significant moderate negative correlation with the cervical length (r=-0.589, p=0.001).Conclusions: Success of labor induction in women undergoing induction due to prolonged pregnancy can be highly predicted by cervical length as it is more objective and accurate than Bishop Score. The 25 mm cut-off point for cervical length was the best predictor of vaginal delivery.

<p class="abstract"><strong>Background:</strong> Squamous Cell Carcinoma (SCC) comprises about 95% of laryngeal malignancies. Translaryngeal Fine Needle Aspiration Cytology (TLFNAC) of endolaryngeal and hypopharyngeal malignancies helps in early diagnosis. Although the diagnosis of a malignancy is often self-evident to a clinician, a tissue diagnosis is a must for starting treatment. TLFNAC helps the clinicians to plan the management at the earliest. Hence this study is to evaluate the utility of percutaneous translaryngeal FNAC in diagnosis of laryngeal lesions.</p><p class="abstract"><strong>Methods:</strong> 189 Cases of Translaryngeal FNACs done during the period of Jan 2014 to Dec. 2015 were retrieved from the cytology register. FNAC was always done after Head and Neck radiology image studies. Usual FNA procedure was followed. FNA done with or without guidance and at times with clinician’s assistance. Smears stained with MGG and Pap stain, and cytomorphological diagnosis was made. </p><p class="abstract"><strong>Results:</strong> Out of 189 cases, aspirates were satisfactory in 146 cases and unsatisfactory in 43 cases. Of the 146 cases, 122 were SCC, pleomorphic adenoma one case, adenoid cystic carcinoma one case, 8 were uncategorized neoplasms and one case was granulomatous inflammation and remaining 14 cases had nonspecific findings.</p><p class="abstract"><strong>Conclusions:</strong> TLFNA is simple, cost effective, less invasive and safe as compared to DL biopsy with less turnaround time for laryngo-pharyngeal lesions. This reduces the number of visits to OT and helps the clinicians in planning the treatment early like RT/CT or surgery. This avoids tracheostomy in borderline airway obstruction cases.</p>
