Lima-Soares, F, Pessoa, KA, Torres Cabido, CE, Lauver, J, Cholewa, J, Rossi, FE, and Zanchi, NE. Determining the arterial occlusion pressure for blood flow restriction: Pulse oximeter as a new method compared with a handheld Doppler. J Strength Cond Res 36(4): 1120–1124, 2022—In laboratorial and clinical settings, the use of Doppler ultrasound equipment has been considered the gold standard method to determine arterial occlusion pressure (AOP). However, the use of Doppler equipment is inherently limited to the technical expertise needed to perform AOP measurements. To overcome the technical difficulties of the use of Doppler equipment use in the determination of AOP, a simpler and less subjective methodology would be helpful for blood flow restriction (BFR) practitioners. In this regard, portable pulse oximetry has been largely used in clinical practice for measuring systolic pressures, as well as loss or recovery of pulse, with results similar to those observed with the use of Doppler equipment. For such purposes, the AOP from young male and female subjects was evaluated after different body positions (standing, seated, and supine positions). Loss of capillary blood flow or AOP was readily determined by simple visual inspection for the pulse oximeter and loss of sound for the Doppler equipment. The results presented herein strongly suggest the use of the portable pulse oximetry equipment as reliable, when compared with the handheld Doppler (seated k = 0.962, standing k = 0.845, and supine k = 0.963 and seated rs = 0.980, standing rs = 0.958, and supine rs = 0.955). Because AOP measurement by pulse oximetry is relatively easier to perform and financially more accessible than handheld Doppler equipment, BFR practitioners may benefit from this new methodology to measure AOP, thus determining individualized restriction pressures.

Bertoli, J, de Souza Bezerra, E, Dias Reis, A, Amice da Costa Barros, E, Gobbo, LA, and Forte Freitas Júnior, I. Long-term side effects of breast cancer on force production parameters. J Strength Cond Res 36(5): 1450–1458, 2022—Breast cancer treatments have long-term side effects, which are associated with muscle strength reduction, negatively affecting the quality of life and increasing the chances of a sedentary life style. The aim of this study was to analyze the effects of types of surgery and hormone therapy on muscle strength parameters in breast cancer survivors compared to women without cancer (control). Eighty-three women, 42 breast cancer survivors and 41 control women, volunteered to participate in this study. Subjects performed maximal isometric voluntary contractions, so that force parameters of the right and left shoulder abductor, trunk extensor, and preferred knee extensor-flexor muscles could be evaluated. Overall, breast cancer survivors presented a lower absolute and normalized maximal force (Fmax) for all muscle groups compared with control. The right shoulder abductor muscles of breast cancer survivors presented a significantly lower absolute and normalized rapid force index (RFI) than control. When compared according to hormone therapy treatment, in breast cancer survivors undergoing aromatase inhibitor, all strength parameters except for normalized RFI demonstrated lower values for the right and left shoulder abductors, trunk, and knee extensors compared with control and tamoxifen. When separated by surgery type, breast cancer survivors who underwent quadrantectomy and radical mastectomy presented lower values for some strength parameters for the left and right shoulder abductors, except for trunk extensor muscles, in which quadrantectomy and total mastectomy presented lower strength parameters. It is recommended that breast cancer survivors should be encouraged to perform supervised strength training programs for different muscle groups to improve Fmax and RFI, aiming to reduce muscle weakness and pain, and improve functional capacity and quality of life.

Tsoukos, A, Brown, LE, Terzis, G, Veligekas, P, and Bogdanis, GC. Potentiation of bench press throw performance using a heavy load and velocity-based repetition control. J Strength Cond Res 35(2S): S72–S79, 2021—The acute effects of heavy load bench press exercise on subsequent bench press throw (BPT) performance and surface electromyographic (sEMG) activity were examined using movement velocity control. Eleven resistance-trained men completed 3 conditions in randomized and counterbalanced order. In 2 conditions, bench press was performed as fast as possible against a load of 80% of 1 repetition maximum, until mean velocity dropped to 90% (C90) or 70% (C70) of the fastest repetition. In the control condition, no bench press was performed. Single maximal BPT efforts were performed in all conditions after warm-up and throughout the 12 minutes of subsequent recovery. Mean propulsive velocity (MPV), peak velocity (PV), and sEMG activity of the prime mover muscles were measured during the BPT efforts. The total number of repetitions and volume load during bench press were significantly greater in C70 compared with C90 (6.5 ± 1.9 vs. 3.4 ± 0.9 repetitions and 557.8 ± 177.8 vs. 293.8 ± 95.7 kg, p < 0.01). In C90, MPV was increased 5.3–7.4% (p < 0.01) for a prolonged period (4–12 minutes), while in C70, MPV increased only at 10 minutes (+5.9%, p < 0.01) and 12 minutes (+4.3%, p < 0.01). Peak velocity was improved only in the C90 at 8–12th min by 3.6–4.7% (p ≤ 0.05). Surface electromyographic activity of the pectoralis major muscle was significantly greater than baseline at 10 minutes of recovery only in the C90 (p < 0.01). Performance gains may be optimized by taking into account the individual fatigue profiles, allowing a percentage drop of only 10% in movement velocity during the conditioning bench press exercise.

¿Hay espacio para el uso de animales en la enseñanza de la biología? Reflexiones desde una perspectiva ecológica y multinivel
Authors: De Giuseppe Bianca Camila , Zapico Martín Gonzalo
Published: May 2020

En este ensayo abordaremos las problemáticas vinculadas a la manipulación de animales para la enseñanza de la biología. Partiendo de un modelo ecológico, se sostiene la hipótesis de que el empleo de animales para la enseñanza de la biología no solo no es ético, sino que tampoco es rentable, eficaz, ni favorece el desarrollo de habilidades sociales fundamentales como la empatía, llegando, incluso, a manifestarse efectos psicológicos adversos en estudiantes expuestos a dichas situaciones. Para la apoyatura de este enunciado, se acudirá a evidencia teórica, práctica y experimental. Concluimos, a partir de nuestro análisis, que la eliminación de las prácticas que involucran la manipulación de animales favorecería no solo a los mismos animales y a quienes las ponen en práctica, sino a la sociedad en su conjunto, pues se estarían formando, desde los primeros años de escolarización, sujetos con inteligencia ecológica y empatía animal, rasgos que favorecen un trato amable y ético hacia el medio ambiente.

El objetivo del presente escrito es propiciar una autoconciencia en el cuerpo docente, con el fin de liberar su praxis de los vicios tradicionalistas y propiciar la transformación del estudiantado, como producto de esa liberación.
Tradición cristiana y educación para los derechos humanos: crítica al sentido moral de Nietzsche
Authors: Mujica Johnson Felipe Nicolás , Orellana Arduiz Nelly Del Carmen
Published: May 2020

La filosofía de los derechos humanos contiene la aportación de diferentes tradiciones de pensamiento que han influido en el progreso moral de la humanidad y entre ellas está la tradición cristiana, que contribuyó al concepto de persona y su inherente dignidad universal. No obstante, existen pensadores que niegan el potencial moral de dicha perspectiva, de modo que en este ensayo se abordará el pensamiento de una de ellas. Entonces, el objetivo del presente documento es contrastar las ideas axiológicas del filósofo Friedrich Nietzsche con la esencia de la moral cristiana y su contribución a la educación de los derechos humanos. Así, se descubre que no es cierto que el sentido moral cristiano se oriente a debilitar o enfermar a las personas, sino que enfoca a su fortalecimiento moral. Precisamente, se hace con la finalidad de que puedan vencer las limitaciones vitales o fisiológicas que dificultan sacrificar el bienestar subjetivo por uno objetivo en el nivel individual y colectivo. De lo contrario, si no se trasciende la naturaleza, no es posible aspirar a fines espirituales como la fraternidad universal. En consecuencia, se reconoce que es fundamental potenciar, en los contextos pedagógicos, una inalienable actitud filosófica frente a los derechos humanos.

Published: May 2020

Herein, we report the physical, chemical, and biological treatment of wastewater generated in the teaching laboratories at Universidad Nacional, Costa Rica. Initial physicochemical treatment included neutralization and coagulation-flocculation, followed by a biological treatment with fungi (Aspergillus sp. and Penicillium dipodomyicola) or bacterias, the latter were isolated from the sludge from the campus’ wastewater treatment plant and the greywater collection tank at the School of Chemistry. The samples’ pH prior to treatment was ≤ 2, while COD ranged between 3000 and 30 000 mg/L. Gas chromatography-mass spectra analysis indicated the presence of 55 organic compounds in the wastewater, some of which reached undetectable concentrations after treatment. The fungi and the bacterial strain removed up to 50% of the substances, while the toxicity decreased with respect to time of exposure to the treatment. Results support the potential use of these microorganisms as bioremediators. Although the organic compounds were partially removed, the treated wastewater exhibited high toxicity for Daphnia magna (water flea). Further experiments with longer treatment times or other strains might be needed for effective removal of pollutants.

Squamous cell carcinoma (SCC) is the most common malignant neoplasm of the skin in cats. Tumour angiogenesis is the pivotal event for tumour progression and metastasis. We assessed protein and gene expression of angiogenic growth factors including bFGF, VEGF-C, TGF-β, PDGF-A, PDGF-C and PDGFR-α that possibly contribute to the angiogenic phenotype of feline SCC (FSCC) and could, therefore, be a good target in the treatment of SCC. In the present study, a total of 27 FSCC cases were investigated. Tumour cases were histopathologically classified as well differentiated (10/27), moderately differentiated (5/27), and poorly differentiated (12/27). The expression levels of the growth factors were detected using immunohistochemistry and assessed semi-quantitatively. Growth factor expression levels were evaluated at different locations: in the oral region, in areas exposed to solar UV radiation including the ears, eyelids and nasal planum, and other miscellaneous locations. Our findings have revealed that FSCC arising from different anatomical sites of the body and showing differences in aggressiveness, metastasis, and prognosis may be angiogenesis dependent, and angiogenic key regulators could play a role in the development of FSCC.

Integral bases of pure fields with square-free parameter
Authors: Remete László
Published: May 2020

Let m ≠ 0, ±1 and n ≥ 2 be integers. The ring of algebraic integers of the pure fields of type is explicitly known for n = 2, 3,4. It is well known that for n = 2, an integral basis of the pure quadratic fields can be given parametrically, by using the remainder of the square-free part of m modulo 4. Such characterisation of an integral basis also exists for cubic and quartic pure fields, but for higher degree pure fields there are only results for special cases.

In this paper we explicitly give an integral basis of the field , where m ≠ ±1 is square-free. Furthermore, we show that similarly to the quadratic case, an integral basis of is repeating periodically in m with period length depending on n.

Perhitungan Nilai Efisiensi Pencacahan Hampiran Untuk Detektor HPGe Pada Spektrometer Gamma Menggunakan Metode Kuadrat Terkecil
Authors: Kurniawan Nazly , Setiawanto Anto , Ramadania Puspitasari
Published: May 2020

Spektrometer gamma merupakan salah satu perangkat spektroskopi nuklir yang sering digunakan untuk pelaksanaan karakterisasi radiologis, yang terkait dengan aspek keselamatan radiologis pengoperasian reaktor riset. Oleh karena itu, dibutuhkan spektrometer gamma dengan performa yang baik, untuk menjamin penerapan aspek keselamatan tersebut. Salah satu indikator yang merepresentasikan performa dari suatu perangkat spektrometer gamma adalah performa analisis kuantitatif dari perangkat spektrometer gamma tersebut, yang sangat bergantung dengan efisiensi pencacahan dari detektor pada spektrometer gamma tersebut. Apabila sampel yang akan dianalisis sama dengan sumber standar yang dimiliki, maka efisiensi pencacahan dapat diperoleh dengan menggunakan metode komparatif. Namun, hampir tidak mungkin untuk menyediakan semua sumber standar yang sama dengan sampel yang akan dianalisis. Sehingga, untuk analisis kuantitatif suatu sampel yang berbeda dengan sumber standar yang tersedia, dibutuhkan nilai efisiensi pencacahan hampiran untuk rentang energi gamma tertentu. Pada tulisan ini, diberikan hasil penerapan metode kuadrat terkecil untuk perhitungan nilai hampiran dari efisiensi pencacahan detektor HPGe pada salah satu spektrometer gamma yang dikelola di Pusat Reaktor Serba Guna, untuk rentang energi dari 53,155 keV sampai dengan 1.332,502 keV. Dari percobaan yang telah dilakukan dengan menggunakan salah satu set sumber standar yang tersedia, diperoleh nilai relative error maksimum sebesar 4,01%. Perolehan nilai relative error tersebut sudah memenuhi kriteria keberterimaan yang ditetapkan untuk nilai relative error terhitung, yaitu kurang dari 10%. Dengan demikian, metode kuadrat terkecil dapat digunakan untuk menentukan nilai efisiensi pencacahan hampiran; dengan prosentase kesalahan hasil perhitungan yang rendah, apabila proses pencacahan telah dikondisikan sesuai dengan persyaratan standar.             Kata kunci : Spektrometer Gamma, Analisis Kuantitatif, dan Kurva Kalibrasi Efisiensi

Authors: Gusman Ranji , Suherkiman Heri , Sujarwono Sujarwono , Sukino Sukino
Published: May 2020

Sistem alarm kebakaran merupakan salah satu bagian dari sistem instrumentasi dan kendali di PRSG. Setelah digunakan lebih dari 30 tahun, sistem ini banyak mengalami gangguan berupa seringnya muncul alarm palsu (false alarm). Disamping itu beberapa sensor telah mengalami kerusakan sehingga tidak dapat mendeteksi apabila terjadi kejadian kebakaran di PRSG. Sistem alarm kebakaran yang lama masih menggunakan sensor yang terdapat zat radioaktif berupa Amerisium (Am-241) untuk mendeteksi asap yang secara aturan internasional telah dilarang penggunaannya. Seiring dengan perkembangan teknologi, sistem baru yang dipasang dapat dilakukan pemrograman sehingga dapat memudahkan teknisi dalam melakukan perawatan dan membantu operator dalam mendeteksi kebakaran karena dilengkapi dengan tampilan Human Machine Interface (HMI). Karena alasan tersebut, maka sistem alarm kebakaran ini perlu dilakukan revitalisasi agar sistem dapat bekerja secara baik dalam mendeteksi kebakaran. Sistem ini terdiri dari 4 jenis sensor yaitu sensor aktif berupa sensor asap dan suhu, sensor asap berupa kamera, sensor pasif berupa kotak alarm manual (manual call point), dan sensor jalur alarm (alarm line). Keempat jenis sensor ini dipasang mengelilingi jalur alarm kebakaran seluruh gedung di PRSG dan mengirim sinyal ke panel kendali alarm kebakaran kemudian alarm tersebut ditampilkan pada panel tegak di Ruang Kendali Utama (RKU). Metode revitalisasi dilakukan dengan mempelajari sistem yang lama, melakukan pengumpulan data Input/Output (I/O), instalasi sistem dengan mengganti seluruh komponen dari sistem yang lama, pembuatan program, dan pembuatan tampilan HMI. Hasil pengujian menunjukkan sistem alarm kebakaran dapat bekerja dengan baik dalam mendeteksi kebakaran di PRSG dan dengan cepat dapat memudahkan operator dan petugas pengamanan dalam menemukan titik dimana kebakaran terjadi.Kata kunci: revitalisasi, sistem alarm kebakaran, PRSG

edilemeyeceği üzerinedir. Biz bu çalışmamızda Kutup’un Benna döneminden
itibaren İhvanla olan ilişkisinin boyutlarına değinerek, Kutup’un siyasi ve
dini çizgisinin netleşmesine ışık tutacağı düşüncesindeyiz.
OSMANLIDA DEĞİŞİM ÇABALARI VE MEHMET SADIK RIFAT PAŞA
Authors: ÖZTÜRK Rahime Hülya
Published: May 2020

Osmanlı Devleti’nde 16. Yüzyıldan itibaren yaşanan gelişmeler ve devletin eski ihtişamını kaybetmeye başlaması gerek sosyal ve askeri yapıda gerekse iktisadi yapıda pek çok değişimi beraberinde getirmiştir. Yaşanan olumsuz gelişmelerin önlenebilmesi için gerekli düzenlemelerin yapılması ise devletin iktisadi hayata bakış açısında geniş çaplı değişiklikleri içeren bir iktisat politikasının varlığını gerektirmektedir.
Devletin dağılmasını önlemek isteyen aynı zamanda iktisadi gelişmeyi sağlayarak eski güçlü devlet yapısını sürdürmek isteyen devlet adamları devletin bütünlüğünü sağlayacak alternatif bir politika olarak kameralizm ile tanışmışlardır. Viyana Büyükelçisi Sadık Rıfat Paşa, Avrupa’da yaşanan gelişmeleri Bab-ı Ali’ye aktarmada ve Tanzimat esaslarının belirlenmesinde etkili olmuştur.
Bu makalenin birinci bölümünde kameralizmin temel ilkeleri ortaya konmaya çalışılmış, uygulandıkları ülkelerde ortaya çıkan sonuçlar tartışılmıştır. İkinci bölümde Avusturya Başbakanı Metternich’in kameralizme bakış açısı değerlendirilmiştir. Üçüncü ve son bölümde ise kameralizm politikalarını Osmanlı devletiyle tanıştıran Avusturya büyükelçisi Sadık Rıfat Paşa’nın görüşleri ele alınmıştır.

La espiritualidad es reconocida como un factor que contribuye a la salud de las personas. En el caso de los adultos jóvenes, este aspecto incide en su autoestima, salud mental, patrones de socialización, conductas de autocuidado y comportamiento. El objetivo del presente trabajo fue describir el bienestar espiritual de los adultos jóvenes del municipio de Libertador San Martín, Provincia de Entre Ríos (Argentina), a partir de los factores Fe - Creencias, Vida - Autorresponsabilidad y Satisfacción con la vida. Se utilizó la escala de Bienestar Espiritual JAREL y se encuestó a 250 personas, en su mayoría mujeres (62%), menores de 30 años (65%), solteros (57%) y con estudios universitarios en curso (50%). El factor mejor percibido fue “Satisfacción con la vida” y se identificó mejor bienestar espiritual en los mayores de 30 años, con hijos, extranjeros, quienes conviven con amigos y familiares, y con estudios universitarios. Se resalta la necesidad de considerar la espiritualidad como una característica esencial del cuidado de enfermería y se sugiere realizar estudios que identifiquen la relación del bienestar espiritual con las conductas de autocuidado y los patrones de afrontamiento a los problemas en la población adulta.
Znajomi Norwida z albumu Marii de Bonneval
Authors: Cedro Adam
Published: May 2020

Artykuł ogólnie charakteryzuje zawartość albumu fotograficznego z XIX w., należącego do Marii de Bonneval z Gerliczów, siostrzenicy Konstancji Górskiej. Na tle dziejów ówczesnej fotografii i historii zdjęć cdv, które zrewolucjonizowały ówczesny rynek i obyczajowość, przedstawiona zostaje – z wykorzystaniem nieznanych dotąd materiałów – sylwetka właścicielki albumu, w której paryskim domu Norwid przez kilkadziesiąt lat gościł na prawach niemal domownika. Okazuje się, że z obejmującego 200 fotografii albumu, będącego obecnie w posiadaniu Fundacji Rodzinnej Blochów, ponad 70 postaci to osoby znane Norwidowi. Mamy więc sposobność po raz pierwszy zobaczyć podobizny wielu z nich, a album możemy traktować niemal jak dokument należący do samego Norwida.
Considerações sobre Erros Ortográficos Envolvendo os Ditongos Variáveis
Authors: Adamoli Marco Antônio
Published: May 2020

O presente artigo focaliza o erro ortográfico referente à grafia dos ditongos variáveis do Português Brasileiro “ai”, “ei” e “ou”, em textos produzidos por crianças em fase de alfabetização, nos quais são constatados casos tanto envolvendo inserção de semivogal (caichoeira, goustou), quanto apagamento dessa estrutura (fejão, caxa). Os trabalhos que se ocupam desse assunto revelaram duas tendências para o surgimento de erros envolvendo essa classe de ditongo, a saber, a influência da oralidade e do próprio processo de escolarização. Ainda que incorretos em termos gramaticais, tais desvios indiciam a construção de hipóteses da criança que, muitas vezes, toma como base para sua escrita aquilo que já aprendeu sobre estruturas linguísticas da língua.
Preposições Introdutoras de Orações Infinitivas em Português Brasileiro
Authors: De Brito Machado Daniel
Published: May 2020

Este artigo tem como objetivo discutir a análise tradicional de marcador de Caso para as preposições gramaticais/funcionais no âmbito da Teoria Gerativa, bem como investigar as suas propriedades semânticas e sintáticas em contextos de oração infinitiva, em oposição aos contextos de complementação por sintagma determinante. Já se demonstrou em trabalhos anteriores (SALLES, 1992; MACHADO, 2013) que a preposição introdutora de oração infinitiva em contexto de complementação está mais sujeita a flutuações entre a preposição de e em e, por vezes, com do que a preposição que licencia o sintagma determinante. Dessa forma, este artigo toma como base essa diferença de comportamento gramatical para reforçar as análises de não marcação de Caso em relação às preposições diante de orações não finitas, estendendo a análise à preposição para, que carrega uma semântica específica nesses mesmos contextos.
Metáfora, Contexto e Incorporação na Retórica Neopentecostal
Authors: Miletta Martins Erik Fernando , Costa De Souza Marcela
Published: May 2020

Segundo Hunt (2000), as igrejas neopentecostais têm como característica central a capacidade de adaptação a contextos espaço-temporais variados. Isto posto, neste artigo trabalhamos com a hipótese de que transformações ocorridas no contexto sociopolítico nacional ao longo de uma década afeta a produção textual-interativa presente em sermões neopentecostais. O foco de nossa atenção está no emprego de metáforas, fundamentais ao sucesso da retórica neopentecostal (MARTINS, 2011; 2015, 2017). Para alcançar os resultados, analisamos a relação entre a conceptualização metafórica da categoria INVESTIMENTO e a incorporação (HANKS, 2008) de mudanças no habitus (BOURDIEU, 1996) do público-alvo em dois cultos, um ministrado no ano de 2007 e outro no ano de 2017. Os resultados apontam que, em 2007, a categoria INVESTIMENTO é conceptualizada em termos determinísticos de um percurso. Já em 2017, o locutor conceituou INVESTIMENTO em termos de uma escolha. Ao longo da análise apontamos possíveis motivações para esta diferença e, em nossa conclusão, sugerimos que na retórica neopentecostal a incorporação do contexto sociopolítico ao discurso produz efeitos na construção de estratégias argumentativas direcionadas à adesão às práticas financeiras, como os dízimos e as ofertas.
