Published: June 2022

Schiff base ligand, 2-acetylpyridine 4-methyl-3-thiosemicarbazone (Me-LH), and its organotin complex (BuSn(Me-LH)Cl2) were synthesized, characterized, and subjected to corrosion inhibition study. The spectra and crystal structure obtained revealed that the ligand is coordinated by pyridyl nitrogen, azomethine nitrogen, and thiolate sulfur to organotin (IV) ion. Corrosion inhibition of the synthesized compounds on mild steels in 1 M HCl solution at different concentrations were tested using weight loss, Electrochemical Impedance Spectroscopy (EIS), potentiodynamic polarization, Scanning Electron Microscopy (SEM) and adsorption analyses. Corrosion inhibition results showed that the complex had a strong corrosion inhibitory effect in comparison to the ligand. The inhibition efficiency of all the techniques improved with an increase in the concentration of corrosion inhibitor. Polarization analysis results showed that the compounds can be categorized as mixed-type inhibitors. Meanwhile, the EIS study indicates that with an increase in the concentration of corrosion inhibitor, the resistance to charge transfer increased. This resulted in the adsorption of inhibitors and the development of a protective layer on the mild steel surface which was further confirmed by SEM analysis. The adsorption isotherm of compounds on a mild steel surface followed the Langmuir isotherm model.
HIGHLIGHTS

The efficient method to inhibit the corrosion rate of mild steel in an acidic medium is a corrosion inhibitor
The electrochemical and weight loss analysis proved that the corrosion inhibition efficiency increases when the concentration of inhibitor is increased
The study proved that the thiosemicarbazone complex showed the potential as corrosion inhibitors at low concentrations

GRAPHICAL ABSTRACT
Kulturalni rasizam, primordijalni lijaliteti i etničko čišćenje / Cultural Racism, Primordial Loyalties, and Ethnic Ceansing
Authors: Delibašić Asim 
Published: June 2022

The purpose of this paper is to provide insight into the individual and structural causes of ethnic cleansing. The paper argues that the cause of ethnic cleansing is cultural or ethnic racism, and that the structural conditions under which ethnic cleansing occurs in society are modern models of social organization such as democracy and nationalism, which form the context in which interethnic prejudice is unleashed in its full strength. The root of this prejudice, in multicultural post-communist states, is usually a very common form of primordial ethnic loyalties, which, by their irrational and antagonistic nature, in periods of early democratic consolidation of society, almost instantly generate irreconcilable demands and feelings of threat from other ethnicities, causing the conflicts between communities that historically share the same territory.
Tempo em Fragmentos: distopia, temporalidade e consciência histórica na era digital
Authors: Parucker Isabela Gomes , Andrade Daniela Linkevicius de 
Published: June 2022

Podemos compreender a escrita da história como esforço criativo de configuração de imagens para representar o movimento do tempo, observando a mudança das coisas e a passagem deste tempo. Por meio de narrativas que entrelaçam acontecimentos e tramam enredos historiográficos, a história torna o tempo inteligível, acessível e compreensível quando transformado em temporalidade. O objetivo do presente artigo é buscar conceitos capazes de iluminar esse processo de temporalização do tempo na contemporaneidade, marcado pela ação dos sujeitos no espaço digital, pela presença de tecnologias que aumentam significativamente a velocidade da produção e troca de informação e ampliam as formas de comunicação. Para isso, pretendemos tensionar o conceito de “Atualismo” (ARAÚJO; PEREIRA, 2018), relacionando-o com a estrutura do espaço digital. Acreditamos que tal noção tem o potencial de provocar questionamentos capazes de impactar diretamente o fazer historiográfico no século XXI, tendo em vista a forma como o tempo é percebido e temporalizado. Vislumbramos, nesse cenário, que os desafios que o atualismo propõe aos historiadores giram em torno de dois aspectos: o domínio do espaço digital e a reflexão acerca da possibilidade de estarmos diante da percepção de tempo fragmentado e da configuração de uma consciência histórica cada dia mais distópica.
Rastafari, repatriación y lucha armada en Jamaica: un análisis del activismo de la African Reform Church en clave de la cultura afrocreolé (1959-1960)
Authors: Mogni Ariel Dario 
Published: June 2022

En este artículo se analiza el movimiento rastafari African Reform Church, liderado por el pastor Claudius Henry, en Jamaica entre los años 1959 y 1960, y sus acciones que pretendieron forzar la repatriación hacia Etiopía y la liberación colonial de los afrodescendientes en la isla en los términos del ideal del back-to-Africa. A través del estudio de sus proclamas, las discusiones gubernamentales, del debate público y del juicio a los miembros de la organización, se busca insertar el proyecto del African Reform Church, inconcluso tras su represión, en los sentidos construidos en la larga duración por la cultura afrocreolé, los métodos de autodefensa conformados desde la década de 1930 por el rastafarismo, las ideas de autogestión garveyista y la asociación con una organización más allá de los límites nacionales. Así, la propuesta de Henry y su grupo se convirtieron en un germen de los mecanismos políticos que se desarrollaron con los movimientos del Black Power caribeño y norteamericano a fines de la década de 1960.
Revisiting five decades of 234Th data: a comprehensive global oceanic compilation
Authors: Ceballos-Romero Elena , Buesseler Ken O. , Villa-Alfageme María 
Published: June 2022

Abstract. We present here a global oceanic compilation of 234Th
measurements that collects results from researchers and laboratories over a
period exceeding 50 years. The origin of the 234Th sampling in the
ocean goes back to 1967, when Bhat et al. (1969) initially studied 234Th distribution relative to its parent
238U in the Indian Ocean. However, it was the seminal work of
Buesseler et al. (1992) – which
proposed an empirical method to estimate export fluxes from 234Th
distributions – that drove the extensive use of the 234Th–238U
radioactive pair to evaluate the organic carbon export out of the surface
ocean by means of the biological carbon pump. Since then, a large number of
234Th depth profiles have been collected using a variety of sampling
instruments and strategies that have changed during the past 50 years. The
present compilation is made of a total 223 data sets: 214 from studies
published in either articles in refereed journals, PhD theses, or
repositories, as well as 9 unpublished data sets. The data were compiled from over
5000 locations spanning all the oceans for total 234Th profiles,
dissolved and particulate 234Th activity concentrations (in dpm L−1), and POC:234Th ratios (in µmol dpm−1) from both
sediment traps and filtration methods. A total of 379 oceanographic
expeditions and more than 56 600 234Th data points have been gathered in
a single open-access, long-term, and dynamic repository. This paper
introduces the dataset along with informative and descriptive graphics.
Appropriate metadata have been compiled, including geographic location,
date, and sample depth, among others. When available, we also include water
temperature, salinity, 238U data (over 18 200 data points), and
particulate organic nitrogen data. Data source and method information
(including 238U and 234Th) is also detailed along with valuable
information for future data analysis such as bloom stage and
steady-/non-steady-state conditions at the sampling moment. The data are
archived on the PANGAEA repository, with the dataset DOI https://doi.org/10.1594/PANGAEA.918125
(Ceballos-Romero et al., 2021). This provides a
valuable resource to better understand and quantify how the contemporary
oceanic carbon uptake functions and how it will change in future.

Published: June 2022

The method of measuring Hb levels recommended by ICSH uses the HiCN method. However, it has a high risk due to the toxicity of the reagent. Therefore, the determination of Hb has been developed using the SLS method. According to Oshiro and Mansoor, who both stated that there was no significant difference between SLS and HiCN, this method has two distinct procedures. This study aims to determine the comparison between the measurement results of hemoglobin levels using sodium lauryl sulfate with the Oshiro procedure and Mansoor. The research design used is analytical research. The data obtained from the results of measuring Hb levels with the Oshiro and Manshoor procedures was given to students of the Diploma IV Study Program of Medical Laboratory Technology, Rajawali Health Institute batch 2018, which collected 49 people. The sampling technique used was saturated sampling to reduce the error rate in the study. The results of the normality test of the data in this study showed n of the two procedures was 49 mean±SD for the Oshiro procedure 13.09±0.56 and p = 0.200. Meanwhile, the Mansoor procedure had a meanSD of 13.09±0.57 and a p-value of 0.059. Because the probability of both being p > 0.05, the data is declared normally distributed. The results of the average difference test from the data of this study show the mean±SD of the pairwise difference between the Oshiro and Mansoor procedures is 0.002±0.059 and the p value = 0.811. If P > 0.05, then it is stated that there is no significant difference between the two groups. The conclusion of this study is that the result of measuring Hb levels using the SLS procedure is reliable. Oshiro and Mansoor conform to HiCN and there is no significant difference in the mean results.

High Subsidence Rate After Primary Total Hip Arthroplasty Using a Zweymüller-type Noncemented Implant With a Matte Surface
Authors: Kawai Toshiyuki , Goto Koji , Kuroda Yutaka , Okuzu Yaichiro , Matsuda Shuichi 
Published: June 2022

Introduction:
The surface topography is one key factor that affects the initial fixation of prosthesis in total hip arthroplasty (THA). We aimed to evaluate the mid-term results of a Zweymüller-type noncemented femoral implant (Elance stem) that had a matte surface with a target average roughness of 1.0 to 2.5 μm. The prosthesis was subjected to alkali and heat treatments to enhance its bone-bonding property.

Methods:
In this retrospective study, 30 THAs (27 patients) done using an Elance stem from September 2012 to October 2014 were evaluated clinically and radiographically for a mean follow-up of 6.3 ± 1.7 years after the index THA.

Results:
Stem revision was indicated for six hips (20%). The survival rate with stem revision for any reason was 86.4% (95% confidence interval, 68.9%-94.8%) at 5 years. Stem subsidence >5 mm was noted in 17 hips (56.7%). The survival rate with stem subsidence >5 mm as the end point was 46.6% (95% confidence interval, 29.9%-64.2%) at 5 years.

Conclusion:
The Zweymüller-type noncemented stem with a low-roughness matte surface demonstrated a high subsidence rate, although the bone-bonding property was potentially enhanced by the alkali and heat treatments. Surgeons should be aware that an insufficient surface roughness could lead to poor mechanical fixation of the noncemented stem, even with an appropriate stem geometry and surface chemistry.
