Numerical simulation of three-dimensional passive micromixer based on the principle of Koch fractal
Authors: Xiong Siyue , Chen Xueye 
Published: March 2021

Abstract
In this paper, We arrange the obstacles based on the Koch fractal principle (OKF) in the micromixer. By changing the fluid flow and folding the fluid, a better mixing performance is achieved. We improve the mixing efficiency by placing OKF and changing the position of OKF, then we studied the influence of the number of OKF and the height of the micromixer on the mixing performance. The results show that when eight OKF are staggered in the microchannel and the height is 0.2 mm, the mixing efficiency of the OKF micromixer can reach 97.1%. Finally, we compared the velocity cross section and velocity streamline of the fluid, and analyzed the influence of OKF on the concentration trend. Through analysis, it is concluded that OKF can generate chaotic convection in the fluid, and enhance the mixing of fluids by generating vortices and folding the fluid. It can effectively improve the mixing efficiency of the micromixer.

Abstract

Objectives
The prevalence, clinical characteristics and prognosis of pleural effusions (PEs) associated with ovarian cancer (OC) have seldom been addressed systematically, as in the current investigation.

Methods
All records of consecutive women with a newly diagnosed OC in our institution over a 13-year period were retrospectively reviewed. Features of PEs on CT scans, pleural fluid analyses, need for definitive therapy of PEs, and the influence of PEs on the overall survival (OS) and progression-free survival (PFS) were evaluated.

Results
PEs were observed in 81 (43%) of 189 women with OC, either at presentation of cancer (55 patients) or during the course of the disease (26 patients). The causes of PEs were malignancy (55.5%), unknown (37%), or surgery-related (7.4%). The sensitivity of the cytologic diagnosis of malignant PEs was 79.1%. Sixty percent of malignant PEs required pleurodesis or indwelling pleural catheters for symptomatic relief. The presence of ascites strongly predicted PE development (odds ratio 43.2). Women with PEs fared much worse compared with those without PEs, in terms of OS (26.7 vs. 90.4 months), PFS (9.8 vs. 55.3 months) and tumor recurrences (86.4 vs. 43%). In multivariate analyses, PE remained as a relevant independent variable associated with poor outcome (hazard ratio 9.73 for OS, and 3.87 for PFS). Notably, PEs small enough to preclude tapping, and thus of unknown origin, had a similar bad prognosis as malignant PEs.

Conclusions
OC patients with PEs experience decreased survival, including those with trace effusions not amenable to tapping.
Mechanical Properties and Durability of Mortars Made with Organic-Inorganic Repair Material
Authors: Lee Seungtae 
Published: March 2021

Abstract
The purpose of this study was to evaluate the mechanical properties and durability of mortars made with organic-inorganic repair materials (OIRMs). The ratio between the main resin and hardener of the organic binder was fixed at 2:1 for the fabrication of OIRM mixtures, while the ratio of the inorganic binder was varied. For a performance comparison with OIRM mixtures, a mortar mixture was fabricated with a conventional cementitious repair material (CRM). The mechanical properties of mortars, such as flow, strength characteristics (compressive, flexural, and bonding strengths), drying shrinkage, and absorption, as well as the durability properties, such as freezing-thawing resistance and resistance to chloride ion penetration, were measured to evaluate mortar performance. The experimental results show that the OIRM mixtures had more favorable mechanical properties (except for compressive strength) and durability than the CRM mixture. In particular, the OIRM mixture with a 1:2:12 (resin:hardener:organic binder) ratio exhibited the most outstanding performances. In conclusion, based on the results of this study, OIRMs should be considered promising repair materials for degraded concrete structures in the future.
La violencia contra las mujeres trans en los espacios públicos: Entre el acoso sexual y la transfobia
Authors: Carmona Alvarado Karol 
Published: March 2021

Este estudio tuvo como objetivo principal analizar, mediante el estudio de testimonios de mujeres trans, las manifestaciones del acoso sexual que enfrentan en los espacios públicos y que violentan sus derechos. Se realizó desde un paradigma de investigación cualitativa con algunos elementos de la investigación acción participativa, con un enfoque crítico de derechos humanos. Se trabajó con ocho mujeres trans, quienes brindaron sus testimonios mediante entrevistas a profundad semiestructuradas, las cuales se triangularon o compararon con periódicos, fuentes secundarias y se sistematizaron. Se complementó con una investigación de campo donde se estuvo contacto con el contexto y las personas en estudio. Entre los principales hallazgos: Los espacios públicos dominados por el hetero-patriarcado son, socialmente, destinados para el ejercicio de poder de los hombres contra las mujeres cisgénero y trans. La violencia que enfrenta la población trans desemboca en daños irreparables para sus vidas, compromete su integridad física y emocional y limita su acceso a los derechos humanos. El acoso sexual que viven las mujeres trans es acoso sexual transfóbico, porque se mezcla el acoso sexual con la transfobia. Lo anterior hace necesario que se realicen estudios desde diversas disciplinas que contribuyan a la visibilización histórica, social y política de estas poblaciones, además de contribuir desde la academia a la construcción de un acervo documental que date las acciones, los logros, las vivencias y la historia de las poblaciones trans. Es importante realizar investigaciones desde enfoques cualitativos que acerquen y sensibilicen a quienes investigan con las realidades sociales, culturales y personales de las mujeres trans.

Authors: Mansur Ali , Faizin Afwan 
Published: March 2021

This article aims to describe the influence of religion and culture in the application of human rights values, as well as the dynamics of its acceptance of legislation in Indonesia. Human rights thoughts and struggles had developed in Indonesia prior to the Universal Declaration of Human Rights in 1948. The embryo of this awareness has flourished in the midst of the bad conditions experienced by the Indonesian people due to colonialism. Precisely since the momentum of the birth of the Budi Utomo movement in 1908, it has laid the foundation for the struggle against the application of human rights values and continues to be a snowball effect in the next period and culminated in the proclamation of Indonesia's independence as a sovereign state on August 17, 1945. In historical records, at the moment of independence, it was the first time Indonesia had a written document containing human rights values, in this case Pancasila and the 1945 Constitution (UUD 1945). However, despite being independent, the struggle for the application of human rights values does not mean it will run smoothly without obstacles, The dynamics of socio-political life in Indonesia illustrates how the ups and downs of the application of human rights values in Indonesia, such as the influence of politics, religion and culture. To get the results, the researchers used a qualitative research method with an amperical normative approach.Keywords : Legislation, Human Rights values, politics, religion, cultur. Abstrak:Artikel ini bertujuan memaparkan pengaruh agama dan budaya dalam penerapan nilai-nilai HAM, serta pasang surut penerimaannya pada legislasi perundang-undangan yang berlaku di Indonesia. Pemikiran dan perjuangan Hak Asasi Manusia telah hidup dan berkembang di Indonesia jauh sebelum deklarasi Universal Hak Asasi Manusia pada tahun 1948. Cikal bakal kesadaran tersebut telah tumbuh subur di tengah kondisi buruk yang dialami masyarakat Indonesia akibat penjajahan yang berkepanjangan. Tepatnya sejak momentum kelahiran pergerakan Budi Utomo di tahun 1908, telah meletakan pondasi perjuangan terhadap penerapan nilai HAM dilakukan dan terus menjadi efek bola salju pada masa masa selanjutnya dan membuahkan hasil saat proklamasi kemerdekaan Indonesia sebagai negara yang berdaulat pada 17 Agustus 1945. Dalam catatan sejarah, dengan momentum kemerdekan ini pula Indonesia pertama kali memiliki dokumen tertulis yang mengandung nilai-nilai HAM dalam hal ini Pancasila dan Undang-Undang Dasar 1945. Namun demikian, meskipun telah memasuki alam kemerdekaan, perjuangan penerapan nilai-nilai HAM bukan berarti mulus tanpa hambatan. Dinamika dan perkembangan kehidupan social politik di Indonesia memberikan gambaran bagaimana pasang surut penerapan HAM di Indonesia, mulai dari pengaruh politik, agama serta budaya. Dalam penelitian ini, peneliti menggunakan metode penelitian kualitatif dengan pendekatan noematif empiris.Kata kunci : Legislasi, Nilai-Nilai HAM, Politik, Agama, Budaya.

AbstractSuperabsorbent polymers (SAP) are a new, promising class of chemical admixtures which offer new possibilities in respect of influencing the properties of cement-based materials in the fresh, hardening, and hardened states. Much research work has been done in the last two decades to set the stage for introducing this truly multipurpose agent into the practice of construction. In particular, three RILEM Technical Committees: 196-ICC, 225-SAP and 260-RSC contributed considerably to the related progress by coordinating and combining the efforts of international experts in the field. The major product of the RILEM TC 225-SAP work was the State-of-the-Art Report published in 2012. This comprehensive document covered all topics relevant to the application of SAP as a concrete admixture. Since then further important progress has been made in understanding the working mechanisms of SAP in concrete and the effects of SAP-addition on various concrete properties. The article at hand presents an update on the state-of-the-art and is the concluding document delivered by the RILEM TC 260-RSC.

AbstractDespite the advances and advantages of breastfeeding, the non-nutritive sucking habit, especially that represented by the use of pacifiers, is still common in Brazilian children. It is estimated that two thirds of children will receive bottles and pacifiers at some point in the first year of life. The frequency of use and the possibility of contamination by harmful microorganisms may lead to the development of opportunistic infections affecting the children’s health. The objective of the study was to conduct a microbiological and structural analysis of pacifiers for children treated in public services and daycare centers. A cross-sectional study was carried out with pacifiers for children aged 6 to 36 months. The collected pacifier was placed in a sterile individualized container and transferred to the laboratory for analysis. The children’s pacifiers who are cared for in public health services and day care centers are contaminated not only the dirty ones but also the visually clean ones. The potentially pathogenic microorganisms found were mainly fungi and bacteria, Candida, Streptococcus and Pseudomonas, respectively.

ResumoApesar dos avanços e vantagens da amamentação, o hábito de sucção não nutritiva, principalmente o representado pelo uso de chupetas, ainda é comum nas crianças Brasileiras. Estima-se que dois terços das crianças receberão mamadeiras e chupetas em algum momento no primeiro ano de vida. À frequência de uso e a possibilidade de contaminação por microrganismos nocivos podem levar ao desenvolvimento de infecções oportunistas prejudicando a saúde das crianças. O Objetivo do estudo doi fazer análise microbiológica e estrutural das chupetas de crianças atendidas em serviços públicos e creches. Foi realizado um estudo transversal, com chupetas de crianças na faixa etária entre 6 a 36 meses de idade. A chupeta recolhida foi acondicionada em recipiente individualizado estéril e transferida ao laboratório para analises. As chupetas das crianças que são atendidas em serviços de saúde pública e creches estão contaminadas tanto as sujas quanto as visualmente limpas.

Authors: B. M. Rupakala , Sudha Gajjala Sai , M. P. A. Sai Lakshmi 
Published: March 2021

Background: Hypertensive disorders complicate 5-10% of all the pregnancies and preeclampsia is identified in 3.9%.Preeclampsia is a pregnancy specific syndrome characterized by the development of hypertension and proteinuria in the second trimester of the pregnancy. Microalbuminuria and elevated spot protein creatinine ratio are commonly found in preeclampsia. The aim of this study was to determine microalbuminuria and spot creatinine ratio in early pregnancy as predictors of pre-eclampsia.Methods: The study was conducted among 102 pregnant women by detecting the levels of albuminuria and spot protein creatinine ratio at 10-14 weeks period of gestation. Random urine sample of about 5 ml was taken to analyse the samples for microalbuminuria and spot protein creatinine ratio. All the women included in the study were followed up till delivery to rule out the possibility of developing preeclampsia depending on their microalbumin and spot protein creatinine ratio values.Results: Pregnant women who developed preeclampsia or eclampsia had significantly higher levels of microalbumin and spot protein creatinine ratio.Conclusions: A detailed study among a larger group of population is required to determine that microalbuminuria and spot protein creatinine ratio in early pregnancy are definitive predictors of preeclampsia.
