Introdução: A morbimortalidade da parada cardiorrespiratória depende da eficácia do atendimento. O sucesso da ressuscitação aumenta se iniciada precocemente no local. Indivíduos desinformados e não capacitados podem prestar um atendimento inadequado aumentando os danos. Objetivo: avaliar se sexo, idade, escolaridade e profissão influenciam no conhecimento e nas atitudes do socorrista. Método: Pesquisa aplicada, com questionário do tipo aberto e fechado, quanti-qualitativo. Estudo transversal por amostra de conveniência, utilizada como reflexo de uma população, não probabilística. Resultado: Foram 319 questionários aplicados entre agosto e outubro de 2015. Homens 36%. Idade média 34,3+14,7 anos. Nível superior 55% e médio 40%. Homens e Mulheres dizem que sabem reconhecer um evento, mas os homens se sentem mais aptos (36% x 21,6% p=0,01), sabem o que fazer (51,2% x 38,2% p=0,02), pedem menos ajuda (27,9% x 40,4%) e checam mais sinais vitais (27,9% x 12,5%). Em relação à faixa etária aqueles entre 20 e 60 anos reconhecem menos eventos (40% x 24% p=0,02) e poucos sabiam como pedir ajuda corretamente. Pessoas com nível superior tinham maior capacidade de reconhecer uma parada (45%), mas isso não os diferenciou nos demais itens. Profissionais da área da saúde chamam menos por ajuda, e metade deles não sabe para qual número ligar. Conclusão: Homens, as pessoas mais velhas e as mais jovens estão mais bem preparados para atender uma parada, independente da escolaridade. E profissionais da área da saúde possuem um conhecimento pouco melhor que a população leiga.

Desain penyejuk udara juga dapat diterapkan di bidang kesehatan, dengan standar Cleanroom dapat diperoleh suhu, kelembaban, kenyamanan dan kebersihan yang dibutuhkan untuk ruang steril (ruang bedah). Perancangan pendingin udara dalam hal ini dilakukan dengan menentukan beban pendinginan yang diperlukan untuk ruang steril (ruang bedah), kemudian menentukan ukuran ducting, jalur ducting, dan jumlah penggunaan ducting. Desain ini menggabungkan unit split saluran yang dimodifikasi, kipas booster, filter pra, filter medium, dan filter HEPA dengan menggunakan saluran aluminium preinsulated sebagai saluran udara. Desain dilakukan dengan menggunakan perangkat lunak AutoCAD 2012, Design Tools Duct Sizer, dan Microsoft Excel. Dari hasil perhitungan dan desain didapatkan kebutuhan kapasitas 3 ruang bedah yaitu ducted ducted 100.000 BTUH sebanyak 3 unit, booster fan 3.3 - 4 Di WG sebanyak 3 unit, pre filter 24 "x 24" x 2 "6 set, filter menengah 610 x 610 x 290 mm 6 set, dan filter HEPA 1220 x 610 x 70 mm 12. Untuk ruang steril, tekanan statis yang dihasilkan oleh unit pendingin harus lebih besar daripada tekanan statis yang dihasilkan dari unit yang ada. di ruang semi steril. Dengan kata lain, ruang steril harus memiliki tekanan positif terhadap ruang semi steril. Hal ini dimaksudkan agar udara di ruang semi steril tidak masuk ke ruang steril ketika pintu antar ruangan dibuka. Desain dan perhitungan ruang bedah, suhu nyata yang diperoleh adalah 23 ° C ± 2 ° C dan kelembaban relatif yang diperoleh adalah 60% ± 2%.   Air conditioning design can also be applied in the health field, with cleanroom standard can be obtained temperature, humidity, comfort and hygiene needed for sterile room (surgical room). The design of air conditioning in this case is done by determining the cooling load required for the sterile room (surgical room), then determining the ducting size, ducting path, and the amount of ducting usage. This design combines modified ducted split unit, booster fan, pre filter, medium filter, and HEPA filter by using preinsulated aluminum duct as an air passage. The design is done by using AutoCAD 2012 software, Design Tools Duct Sizer, and Microsoft Excel. From the calculation and design result obtained the capacity requirement of 3 surgical room that is split ducted 100.000 BTUH as many as 3 units, booster fan 3.3 - 4 In WG as many as 3 units, pre filter 24"x 24" x 2" 6 sets, medium filter 610 x 610 x 290 mm 6 sets, and HEPA filter 1220 x 610 x 70 mm 12 sets. For the sterile room, the static pressure generated by the cooling unit shall be larger than the static pressure generated from the unit present in the semi sterile room. In other words, the sterile room must have positive pressure to the semi sterile room. It is intended that the air in the semi sterile room does not enter into the sterile room when the door between room opened. In this surgical room design and calculation, real temperature obtained is 23 °C ± 2 °C and the relative moisture obtained is 60% ± 2%.

Deflagration-to-detonation transition (DDT) in the system “gaseous oxygen- liquid film of n-decane” ' with a weak ignition source was obtained experimentally. In a series of experiments with ignition by an exploding wire that generates a weak primary shock wave (SW) with a Mach number ranging from 1.03 to 1.4, the DDT with the detonation run-up distances 1 to 4 m from the ignition source and run-up time 3 ms to 1.7 s after ignition was observed in a straight smooth channel of rectangular 54 x 24-millimeter cross section, 3 and 6 m in length with one open end. The DDT is obtained for relatively thick films with a thickness of 0. 3-0.5 mm, which corresponds to very high values of the overall fuel-to-oxygen equivalence ratios of 20-40. The registered velocity of the detonation wave (DW) was 1400-1700 m/s. In a number of experiments, a high-velocity quasi-stationary detonation-like combustion front was recorded running at an average velocity of 700-1100 m/s. Its structure includes the leading SW followed by the reaction zone with a time delay of 90 to 190 s. The obtained results are important for the organization of the operation process in advanced continuous-detonation and pulsed-detonation combustors of rocket and air-breathing engines with the supply of liquid fuel in the form of a wall film.

Este trabalho teve como objetivo principal realizar a análise citotaxonômica de espécies filogeneticamente relacionadas dentro dos gêneros Kleberiella, Alatiglossum e Neoruschia com base na determinação dos seus números cromossômicos a partir dos seus meristemas radiculares. Foram obtidos os números cromossômicos de todas as espécies de Kleberiella (seis espécies), Neoruschia (monoespecífico) e de quatro das nove espécies conhecidas para Alatiglossum stricto sensu. Exceto para K. longipes, A. barbatum e A. micropogon, os quais corroboram com resultados anteriores, todos os outros números cromossômicos são inéditos. A contagem cromossômica se mostrou como um caráter taxonômico útil na delimitação de Alatiglossum fuscopetalum (2n = 52) e do gênero Neoruschia (2n = 48) das outras espécies analisadas. Entretanto não se mostrou eficiente para delimitação entre as espécies de Kleberiella (todas com 2n = 56) e para separar este gênero de Alatiglossum no qual a maioria das espécies analisadas apresentou 2n = 56. O numero básico sugerido para Alatiglossum e Kleberiella é x = 28 e para Neoruschia x = 24.

ABSTRACT The limited usefulness of radioimmunoassays of parathyroid hormone in the differential diagnosis of hypercalcaemia invites the use of methods measuring effects of parathyroid hormone (PTH). Data from 4–5-day metabolic studies in 107 hypercalcaemic patients (78 retrospective and 29 prospective cases) were combined in a hypercalcaemia discrimination index (HDI). HDI = (urine calcium (mg/24 h) x 100 x serum phosphate (mg/100 ml))/(serum total calcium (mg/100 ml) x 24-h clearance of creatinine (ml/min)) expresses in one figure the combined actions of PTH on the renal handling of calcium and on serum phosphate. A multivariate analysis confirmed that HDI offered optimal discrimination. An identical discrimination was observed in the prospective series. In the complete series HDI = 137 was the optimal discrimination point. Classification of the patients as having hyperparathyroidism (HPT) or pseudohyperparathyroidism (P-HPT) (< 137) or non-parathyroid hypercalcaemia (NON-PTH) (≧ 137) corresponded in 100 out of 107 patients (93.5%) with the final clinical diagnosis. The effects on HDI of sex, age, season, urine losses, high calcium intake and use of thiazides were also evaluated. HDI appears to be a valuable tool in the endocrine evaluation of hypercalcaemic patients. Used in combination with radioimmunoassays measuring genuine but not ectopic PTH HDI may serve to classify hypercalcaemic patients within the following 3 subgroups: HPT, P-HPT and NON-PTH.
