Pengaruh waktu pelapisan terhadap ketebalan dan kuat lekat pada baja karbon rendah dengan proses elektroplating
Authors: Wijanarko Nurvan , Asroni Asroni , Budiyanto Eko 
Published: October 2021

Baja adalah logam paduan antara besi (Fe) dan karbon (C), dimana besi sebagai unsur dasar dan karbon sebagai unsur paduan utamanya. Elektroplating atau pelapisan secara listrik merupakan proses lapisan suatu logam secara elektrolis melalui penggunaan arus listrik searah (DC) dan larutan kimia (elektrolit). Pelapisan bertujuan untuk membentuk permukaan dengan sifat atau dimensi yang berbeda dengan logam dasarnya. Terjadinya endapan pada proses disebabkan adanya ion-ion pada elektrolit tersebut akan mengendap pada katoda. Penelitian ini menggunakan variasi waktu pelapisan 20 menit, 25 menit, dan 30 menit kemudian dilakukan pengujian ketebalan dan kuat lekat. Dari pengujian yang dilakukan didapatkan hasil waktu pelapisan 30 menit dengan ketebalan rata rata 0,314 mm rata rata nilai kuat lekat 26,79 MPa, waktu pelapisan 25 menit dengan ketebalan rata rata 0,216 mm rata rata nilai kuat lekat 22,58 MPa, waktu pelapisan 20 menit dengan ketebalan rata rata 0,114 mm rata rata nilai kuat lekat 18,95 MPa.
Maruja Mallo (1902-1995): Mujer y Mujeres
Authors: Rodríguez Roldán Rocío 
Published: October 2021

Maruja Mallo es una figura clave dentro de dos ámbitos de la primera mitad del siglo XX español: el artístico, formando parte de los grupos renovadores del arte nacional y de la conocida como Generación del 27, y el feminista, participando en los movimientos de emancipación femenina y convirtiéndose en la encarnación de la mujer moderna. La artista desarrolló su vida como una mujer libre, conquistando logros usualmente reservados al territorio masculino; esta modernidad encontró lugar también dentro de su producción artística, estrechamente relacionada con la representación del concepto de mujer nueva y en la que observamos dos características: la revalorización de elementos tradicionalmente asociados con lo femenino y la creación de un universo habitado por la mujer moderna en el que no existen diferenciaciones por cuestiones de género.
En el presente artículo nos centraremos en el estudio de los símbolos femeninos y las mujeres representadas por la creadora a lo largo de su carrera artística, distinguiendo entre tres etapas creativas y vitales –de las cuales la mujer tiene un papel fundamental en las dos primeras–, y seleccionando diversas obras y series que atestiguan la importancia de la representación de la fémina en la producción de Maruja, tema raramente tratado en el estudio de su obra, ofreciendo también un breve contexto vital con el que entender la modernidad e importancia de la artista.
Capture, Storage and Utilization of Carbon Dioxide by Microalgae and Production of Biomaterials
Authors: Bertolini Marta , Conti Fosca 
Published: October 2021

Abstract
Carbon dioxide emissions are strongly related to climate change and increase of global temperature. Whilst a complete change in producing materials and energy and in traffic and transportation systems is already in progress and circular economy concepts are on working, Carbon Capture and Storage (CCS) and Carbon Capture and Utilisation (CCU) represent technically practicable operative strategies. Both technologies have main challenges related to high costs, so that further advanced research is required to obtain feasible options. In this article, the focus is mainly on CCU using microalgae that are able to use CO2 as building block for value-added products such as biofuels, EPS (Extracellular Polymeric Substances), biomaterials and electricity. The results of three strains (UTEX 90, CC 2656, and CC 1010) of the microalgal organism Chlamydomonas reinhardtii are discussed. The results about ideal culture conditions suggest incubation temperature of 30 °C, pH between 6.5 and 7.0, concentrations of acetate between 1.6 and 2.3 g L–1 and of ammonium chloride between 0.1 and 0.5 g L–1, the addition of glucose This green microalga is a valid model system to optimize the production of biomass, carbohydrates and lipids.

Hymenopteran parasitoids are biological control agents that contribute mortality to economically important pest of oil palm plantations. In this research we investigated the diversity and abundance of Hymenopteran parasitoids at PT. Mopoli Raya, Aceh Province, Indonesia. Data were collected by adopted a purposive sampling method in mature and immature plantations by using light trap, malaise trap, and yellow-pan trap. Specimens were identified at Universitas Syiah Kuala and final taxonomic confirmation was conducted at Gadjah Mada University. We found that the species richness and evenness of the Hymenoptera parasitoid species in mature oil palm plantations tended to be higher than in immature plantations. It is suspected that in immature oil palm plants (4 years) synthetic pesticide application is more intensive and it has a negative impact on the presence of parasitoids compared to the mature.
Te Andean Spanish of Peru Trough Folk Tales: Psycholinguocultural Approach
Authors: Grinina E. A. , Romanova G. S. 
Published: October 2021

National varieties of Spanish have been studied successfully since the second half of the XX-th century. Te object of this research is the Andean varieties of Spanish, which we intend to study from a psycholinguocultural perspective, which is a novel approach, developed by a number of Russian linguists.Te research is aimed at analyzing some linguistic characteristics of the natural bilinguals of the Andean world and answering the questions, if there is a connection between language and ethnicity and if an ethnic group can have two or more linguistic identities. Between language and ethnicity there is a close and direct interdependence. However similar the language spoken by diﬀerent ethnic groups living in the same territory may seem, it is only on the surface, as the language is determined by psycho- and linguocultural factors. A monolingual ethnic group does not usually have more than one linguistic identity, but in diglossia situations, a person who acts as two (or more) speaking subjects, using one or more languages depending on the circumstances, brings together two (or more) linguistic personalities.

Objective: The aim of this study is to evaluate the retinal nerve fiber layer (RNFL) thickness by optical coherence tomography (OCT) in Syrian patients with MS and diseases- free controls and to assess this thickness in MS-ON and MS-NON, and assess the relationship between RNFL thickness Expanded Disability Status Scale (EDSS) score. Although there are many similar studies to evaluate role of OCT at MS patients in different countries and many races,but this study is the first one of using OCT at MS patients in our country. Methods: This study (cross sectional ,case- control) was carried out at Tishreen University Hospital in Latakia. A total of 112 eyes from 56 individuals with an age range from 22 to 43 years were studied. twenty -six patients with definite MS, Diagnosis of MS was based on the MacDonald criteria.The disease-free controls were matched for age and gender (n=30; 60eyes). Retinal nerve fiber layer thickness was measured using optical coherence tomography (Spectralis OCT - Heidelberg Engineering), and gathering information about past ON history since more than 6 months and EDSS. Results: There were statistically Significant differences (p=0.0001) between both groups (case- control) were observed in OCT parameters (average, and all sectors especially temporal and superior sector) with lower RNFL thickness in the MS group (MS-ON,MS-NON).There were statistically significant differences (p=0.0001) between MS-ON (n = 20 eyes) and MS-NON (n = 32eyes) for all RNFL parameters measured by OCT, with lower RNFL thickness in (MS-ON).There were statistically significant inverse correlations was observed between average RNFL thickness and neurologic impairment (Expanded Disability Status Scale) (r=- 0.6، P=0.0001) and all sectors especially in temporal and superior quadrants (r=-7 , P=0.0001). Conclusions: OCT seems to be a reproducible test to detect axonal loss of ganglion cells in MS (RNFL). Further and larger longitudinal prospective studies would be valuable to assess the evolution over time of the RNFL measurements in Syrian MS patients.
Book Review: Michael Giudice, Social Construction of Law: Potential and Limits
Authors: Buckley Erin 
Published: October 2021

That law is socially constructed is so ubiquitous a statement in law and the humanities as to render itself dangerously close to ‘common sense’. The subheading ‘Potential and Limits’ is the key to Giudice’s original argument in which he suggests that law is both socially constructed; yet retains a ‘natural’ core. When teaching critical theory, I encourage students to examine anything they understand as ‘common sense’ as a potential blind spot for bias and assumptions deeply ingrained in ideology. As such, the attempt to examine exactly such a potential blind spot is exactly the sort of problem legal philosophy should seek to address.
Litigating Racial Profiling: The Use of Statistical Data
Authors: Hopkins Tamar 
Published: October 2021

The use of statistical data to prove racial discrimination by police in individual cases is relatively novel in Australia. Based on a survey of international strategies, this article argues that statistical and social science data can play three critical evidential roles in litigation. Firstly, it can form part of the social context evidence used to influence the inferences that can be drawn from other evidence led in a case. Secondly it can influence the cogency of the evidence required for claimants to meet the standard of proof, and thirdly, it can be used to shift the burden of proof. Using these evidential methods, evidence of institutional racism can be used to assist in making findings of discrimination in individual cases. This article speculates on the role that statistics could have played in the Haile-Michael race discrimination claim that settled in 2013, and in the 2019 inquest into the death of Tanya Day.

Published: October 2021

Abstract. Seeds of Argemone mexicana L. accumulate significative amounts of sanguinarine. The analysis of the distribution of this alkaloid through the tissues of mature seeds revealed that up to 60 % of its contents was found tightly fixed to the different components of the seed external covers where it persisted during seedling germination. Contrastingly, sanguinarine contents in cotyledon accounted for the remaining 40 % and it could have been, at least partially, mobilized to the newly formed hypocotyls during emergence from seeds. Berberine was only detected in immature seeds and in seedlings once cotyledons were totally displayed. These results are discussed as a possible sanguinarine role in the chemical protection during seedlings germination.

Resumen. Semillas de Argemone mexicana L. acumulan cantidades elevadas de sanguinarina. Un análisis de la distribución de alcaloides en los diferentes tejidos que componen la semilla reveló que hasta un 60 % del contenido se encontraba fuertemente unido en las capas que forman la cubierta exterior, donde se retuvieron durante la emergencia del hipocótilo. En contraste, los cotiledones presentaron el 40 % restante y parte de ello pudo haber sido movilizado al hipocótilo al emerger. Berberina sólo se observó en semillas inmaduras y en plántulas en desarrollo con los cotiledones desplegados. Estos resultados se discuten en función del posible papel defensivo de la sanguinarina durante la germinación.
