Evaluasi Kerja Nozzle Rig Pada Steam Bench Setelah Perbaikan di Laboratorium Teknik Konversi Energi
Authors: Paquita Sarah Amelia  , Maridjo Maridjo , Manunggal Bambang
Published: July 2023

Nozzle rig pada bangku uap (steam bench) merupakan alat yang berfungsi untuk mengubah energi tekanan dari uap menjadi energi kinetik , dimana tekanan akan diubah dari tekanan yang tinggi menjadi tekanan yang lebih rendah. Uap yang mengalir dalam nozzle akan menempati tempat disekitarnya dengan cepat , maka dari itu ,ekspansi didalam nozzle dikatakan adiabatis. Pada Laboratorium Teknik Konversi Energi di Politeknik Negeri Bandung , nozzle rig pada steam bench tersebut sudah lama tidak digunakan sehingga munculnya indikasi kerusakan pasa nozzle dan pembacaan tekanan yang tidak akurat. Dengan dilakukannya perbaikan maka kinerja pada nozzle rig bisa dilakukan dengan menghitung kecepatan aliran uap, laju aliran massa uap, dan bilangan Reynolds. Penurunan tekanan pada setiap titik probe berbeda-beda tergantung pada berapa tekanan uap yang masuk pada nozzle. Nilai perhitungan aktual lebih kecil dibandingkan dengan perhitungan teoritis dikarenakan adanya losses yang terjadi pada saat uap mengalir pada nozzle. Kecepatan nozzle tertinggi yaitu 4,053 m/s dengan laju aliran massa uap sebesar 1,5517 x 10-5 terdapat pada posisi probe 50 dengan tekanan masuk sebesar 5 bar. Kecepatan nozzle terendah yaitu 1,618 m/s dengan laju aliran massa uap sebesar 8,728 x 10-5 terdapat pada posisi probe -10 dengan tekanan masuk sebesar 5 bar.

Kata kunci : nozzle , uap , perbaikan , kinerja, kecepatan , laju aliran massa.

Teacher’s Age and Experience as a Modifying Factor in the Readiness For and Method of Intervention with a Student at Risk of Psychoactive Drugs
Authors: Waluś Roman , Jasnos Renata
Published: July 2023

This article deals with teacher interventions in crisis situations regarding a direct threat of students using psychoactive drugs on school premises, particularly in the difficult period of adolescence: 12–16 years of age. The focus of the research was on teacher interventions in situations where students are threatened by psychoactive substances. The research problem was whether the age and experience of the teacher were determinants of such an intervention. It investigated the relevance that a teacher’s age and experience have on their attitude and manner of intervening on behalf of a student when there is an imminent threat from psychoactive substances. The research investigated the importance of a teacher’s age and work experience in their attitude and the manner in which they intervene. It was carried out from 2017 to 2019 among teachers at middle schools in Bielsko-Biala, using the diagnostic survey method and a questionnaire. Statistical analysis of the results showed no statistically significant difference in teachers’ declarations of readiness for intervention. Regardless of age and tenure, the respondents declared a high readiness to intervene. On the other hand, there were statistically significant differences according to the teachers’ age and seniority in how the intervention was carried out. Teachers from different age and seniority groups (defined by a specific length of service) more often or less often took some of the actions envisaged in the intervention procedure. Thus, it is feasible to speak of a readiness, or lack thereof, to take certain intervention actions.

Background: This study was conducted to study the variations in the number and location of nutrient and epiphyseal vascular foramina of the femur in the Pakistani population

Methodology: This descriptive cross-sectional study was conducted from April -June '2022 after getting ethical approval. Data collection tool: 24-gauge hypodermic needles & measuring tapes.

Data collection and Analysis: SPSS & Excel

Inclusion & exclusion criteria: Anatomically sound bones were included from the bone bank of RMU; pathological, deformed bones were excluded

Results: Out of 80 bones 66.6% had single nutrient foramina, whereas 31.3% had two on the shaft. 82.05% of foramina were type II, 16.67% were type I and 1.26% were type III. Only 2.5% had no foramina. Majorly the nutrient foramina were found on the medial surface, medial lips or between the lips of linea aspera. There was no significant difference bilaterally in the mean foraminal index, foraminal length, or several epiphyseal vascular foramina, which were 18.65 cm, 42.66 cm, and 16 cm respectively.

Bioassays on the Activity of Resveratrol, Pterostilbene and Phosphorous Acid towards Fungi Associated with Esca of Grapevine
Authors: Mazzullo Alessandro , Cesari Augusto , Osti Fabio , Di Marco Stefano
Published: July 2023

An examination was carried out under laboratory conditions to determine whether resveratrol, pterostilbene
and mixtures of each stilbene with phosphorous acid had an inhibitory activity against some fungi involved in esca:
Phaeoacremonium aleophilum, Phaeomoniella chlamydospora, Libertella blepharis (anamorph of Eutypa lata),
Fomitiporia punctata and Stereum hirsutum. An inhibition of mycelial growth by resveratrol was not found but there
was a clear correlation between pterostilbene concentration and reduction of radial growth confirming the antifungal
activity of this phytoalexin. Although phosphorous acid proved to be generally ineffective, an increase of antifungal
activity of stilbenes in the mixtures was observed with all fungi except F. punctata. The possible relation between
fungal phenol oxidase activity and inhibition by mixtures of stilbenes and phosphorous acid was discussed.
A RECEPÇÃO DOS ESTUDOS SUBALTERNOS NO BRASIL
Authors: Pereira Tiago Júnior Ramos
Published: July 2023

A presente pesquisa objetiva-se examinar a recepção no Brasil, do conceito gramsciano de subalterno e também, compreender sua concepção afixada nos debates e produções acadêmicas. A partir do percurso sócio-histórico que o conceitopercorre, encontra ao longo de sua análise, concepções distintas àquela formulada por Gramsci, na conjuntura em que foi elaborada. A revisão e releitura do termo vão de encontro à projetos que atribuem sentidos e práticas distintas da formulação original. As correntes de pensamento que se utilizam da subalternidade gramsciana, recorrem a criativas leituras, construídas sobre um aparato teórico eclético. Merece destaque a análise historiográfica indiana, no projeto subalternista, que se apropria do conceito e posteriormente se ampara na concepção pós-moderna e pós-estruturalista para subsidiar a crítica pós-colonial, que chega à América Latina e ascende a formação do projeto subalternista latino americano. Pretende-se desse modo, analisar como o sujeito subalterno é definido nos debates no Brasil.
PENSAMENTO POLÍTICO LATINO-AMERICANO
Authors: Mendes Enndiel dos Santos
Published: July 2023

A retomada dos saberes ancestrais, a construção de novas epistemologias e a percepção da própria realidade são instrumentos importantes para uma análise mais ampla dos fenômenos sociais e políticos de regiões que foram palco de processos coloniais. Nesse sentido, o presente artigo busca, por meio de uma revisão de literatura, expor as análises do pensador marxista José Carlos Mariátegui no que diz respeito ao Peru e a América Latina, para contribuir com o debate sobre a elaboração de novas epistemologias políticas nos estudos sociais. Traçamos a hipótese de que o marxista peruano fornece as bases fundamentais para a criação de uma possível epistemologia política latino-americana. Dessa maneira, com o auxílio de autores e autoras que se debruçam sobre a discussão epistemológica e marxista, investigaremos as condições históricas e políticas produzidas pela colonização em prol de fomentar o resgate dos saberes subalternos para o enfrentamento ao universalismo europeu em diversas instâncias do conhecimento.
RAÇA E CLASSE NA AMÉRICA LATINA
Authors: Jesus Yasmin Couto de
Published: July 2023

O presente artigo busca identificar, a partir de uma revisão de literatura, as contribuições do pensamento de Mariátegui sobre a questão indígena para que seja possível entender de que forma a junção do marxismo com o indigenismo, bem como o reconhecimento das reivindicações dos indígenas à terra, tem potencial para encorpar a produção marxista da América Latina sobre a luta revolucionária contra o capital. Para isso, será discutido neste artigo como Mariátegui aborda a realidade do problema do índio a partir do nacional e do internacional, identificando como a interação entre esses implica na necessidade de pensar o marxismo a partir das especificidades do país em questão. Pretende abordar também de que forma a análise materialista e a crítica socialista descobre e esclarece o problema do índio, identificando, portanto, suas raízes social-político-econômicas, tornando-se, portanto, fundamental para a compreensão profunda deste, indo, portanto, além da interpretação rasa que se apoia sobre a solução do problema indígena em uma fórmula humanitária ou filantrópica. E, por fim, discutir a questão da raça na América Latina como eixo fundamental para a análise marxista e para a luta proletária na região.

Published: July 2023

Resumo.

É dever dos verdadeiros progressistas e amantes da paz desmentir e desmontar a implementação da “pós-verdade” contra a Nicaragua, isto é, desmentir as fake news que propagam: a) é uma ditadura comunista populista, b) que está suprimindo a liberdade de imprensa, c) que está aprisionando candidatos da oposição que supostamente eles ganhariam as eleições e d) que persegue dissidentes sandinistas que se oporiam a isso dentro do partido do personalismo ditatorial de Daniel Ortega. O objetivo do artigo é apresentar um panorama histórico sobre a Nicarágua desde a ocupação norte-americana, destacando o papel de Sandino até o desdobramento da revolução sandinista; uma retrospectiva das eleições no país; principais crises até a atualidade e os impactos da guerra híbrida na atual crise que o país enfrenta. Concluí que o que está em jogo hoje na Nicarágua é o destino das conquistas da revolução sandinista.

A crise da democracia brasileira e o papel do extremismo político e religioso
Authors: Ferreira Manuela Lowenthal
Published: July 2023

Este artigo dedica-se a compreender as diversas facetas do avanço da ala conservadora, com variações e intensidades diferentes, no cenário sociopolítico brasileiro e internacional. Nesse sentido, busca-se discutir como a ascensão da extrema direita unida à movimentos conservadores ligados a vertentes pentecostais e neopentecostais no Brasil agem em consonância, ao mesmo tempo que produzem e acionam mecanismos para disputar o espaço público e mobilizar reinvindicações de cunho moral, estabelecendo uma ordenação da esfera social por um tipo específico de associação entre religião, conservadorismo e pensamento neoliberal.

Regional theories, like other theories, include a set of philosophical axioms emanating from the character of the place, and its final formulation came through a series of procedures and scientific corrections focused on the field of place, as the center of interest for regional science, which is the science that explains the factors that dominate how economic and social activities are signed. And the urban and functional relations between them in the spatial space, those activities that launch through them and through them the interactive relationships that make the place characterized by dynamism that cannot be imagined to occur randomly, but according to mutual mechanisms that occur continuously.
