Tankstellen im Alltag sind grundsätzlich unauffällig. Überlandstraßen und Autobahnen saumend, eingefaltet in urbane Raume oder als Element suburbaner, industrieller Zonen nimmt man sie kaum wahr. Werden sie jedoch gebraucht, sei es zum Tanken, sei es zum Einkaufen abseits der üblichen Öffnungszeiten, rücken sie aus ihrer Latenz von einem Augenblick auf den anderen in den Vordergrund der Wahrnehmung und können für Reisende zu einer Obsession werden – rettende Oasen in der Wüste.

Explosion HazardGas Stations in the Coming-of-Age Genre
Gas stations are in-between-places; non-lieux (Marc Augé), places with a special density. In terms of space and metaphor they are often situated at the margins of urban and suburban zones. Gas stations frequently appear throughout popular culture, in novels, films and T V series, often as a threshold to supernatural, uncanny spaces. At a gas station, anything can happen, any time. People meet by chance, continue their trip together, get into fights, fall in love, get killed. And of course, gas stations can explode as soon as safe-ty measures are ignored. In the coming-of-age genre, in particular, there is a huge variety of gas stations: Gas stations as everyday places as well as adventurous zones reflect the fragile emotional state of adolescent characters on the run. When they turn in at a gas station, dramatic things happen – an old order might be destroyed and a new one seems possible. Even though gas stations seem easy to grasp as icons of modernity, they are the result of complex media processes. This article analyses the poetics of the gas station in German coming-of-age-novels, putting them into the context of international media culture for young adults.
África en nosotras y nosotros: un tambor que resuena en el cosmos

Published: September 2021

La cumbia, el bullerengue, el son de negro y el currulao son parte de la herencia viva de África en Colombia; huellas de africanía, como lo refería Nina de Friedemann (1992), que reafirman una presencia antigua y originaria, entre nosotros. La musicalidad ha sido esencial para los estudios y el pensamiento sobre identidad, cultura negra y la condición de las comunidades afrodescendientes en Améfrica (Du Bois, 1999; D. Zapata, 1962; M. Zapata, 2000; García, 1994; Miller, 2009; Segato, 1995; Mukuna, 1978; Quintero, 2000). Esta noción que acuñó la afrobrasilera Léila Gonzalez (1988) da cuenta de la africanización del continente americano, que incluye los territorios del norte, centro, sur e insular (Caribe).

Published: September 2021

Introducirse en el mundo laboral es costoso y uno de los primeros obstáculos es el déficit competencial que, en ocasiones, presentan los universitarios. Para subsanar el exceso de una teoría descontextualizada, el EEES (Espacio Europeo de Educación Superior) ha auspiciado un cambio metodológico que fomenta una docencia más práctica, ya que el aprendizaje más efectivo es activo y está conectado con la experiencia. De este modo, la enseñanza universitaria se enfoca, entre otros aspectos, en la consecución de resultados de aprendizaje en forma de competencias asociadas al mercado laboral. En este contexto se están ensayando en la universidad [española] metodologías más prácticas y aplicadas, entre ellas, el Aprendizaje-Servicio.
El objetivo de este trabajo es conocer si para los empleadores participantes en nuestro estudio, los universitarios que participan en actividades de Aprendizaje-Servicio desarrollan el perfil competencial que buscan, haciéndoles candidatos más atractivos en los procesos de selección, mejorando en consecuencia su empleabilidad. Para ello, se desarrolló una investigación cualitativa genérica. Se realizaron tres grupos focales en los que participaron por muestreo intencional trece empleadores de egresados de distintas facultades de la universidad, pertenecientes a distintos sectores. La guía temática incluía preguntas sobre las competencias más demandadas por los empleadores, el Aprendizaje-Servicio y su influencia en el perfil profesional. La transcripción textual fue analizada mediante análisis de contenido inductivo por dos investigadores. En el apartado de resultados y discusión se constató que, para los empleadores consultados, los alumnos que participan en actividades de Aprendizaje- Servicio en la universidad, desarrollan algunas de las competencias profesionales más demandadas en el mundo laboral, incidiendo positivamente en su empleabilidad.
LA AFECTIVIDAD EN EL APRENDIZAJE DEL IDIOMA INGLÉS COMO SEGUNDA LENGUA
Authors: Romero Zárate Martha , Santana Valencia Emma Verónica 
Published: September 2021

Durante el proceso de aprendizaje de una segunda lengua es posible observar circunstancias diversas que repercuten en él: motivación, interés o desinterés, estrés o cierta sensación de angustia..., que pueden impactar en la adquisición de conocimientos, manifestándose en actitudes positivas o negativas. En el ámbito educativo, la afectividad bien encauzada puede minimizar estas situaciones que impiden al estudiante involucrarse con mayor entusiasmo en su trabajo académico, y en el caso del aprendizaje de una segunda lengua, contribuir a una formación integral.
En este sentido, el presente trabajo presenta una revisión teórica sobre la afectividad en el aprendizaje de una segunda lengua en el contexto universitario y la forma en que este es un soporte para considerar a los estudiantes como seres humanos que requieren de tiempo para integrarse a un ambiente de trabajo, así como de un impulso que los guíe en el proceso de aprendizaje, con paciencia y seguridad, propiciando situaciones de confianza para desarrollar interacciones comunicativas más fluidas con sus pares.

Fortification of a Desert Using Nanoencapsulated Supercritical Carbon Dioxide Extract of Small Cardamom Seeds: A Nutraceutical Custard with Antioxidant Synergy
Authors: Paul Kaninika , Tamili Dipshikha , Bhattacharjee Paramita 
Published: September 2021

Background:
1,8 cineole-rich supercritical CO2 extract of small cardamom
seeds of Alleppey green variety exhibiting prominent antioxidant property was microencapsulated
and utilized in formulating an antioxidant-rich custard. However, the antioxidant
potency of the prepared custard was not appreciable. To redress the phytochemical
loss during custard preparation, custard using nanoliposomes was formulated. Patents related
to 1,8 cineole-rich food products have been revised thoroughly.

Objective:
: The objective of the current study is to examine whether nanoencapsulationmediated
entrapment of antioxidants is more effective in fortifying a dessert, namely custard,
vis-à-vis microencapsulated (spray dried)-mediated enhancement of antioxidative
potency in the same.

Methods:
Our previous investigations have established that nanoliposome of 1,8 cineole-
rich supercritical CO2 extract of small cardamom seeds effectively redresses type 2 diabetes
and hypercholesterolemia. In the current investigation, this pre-characterized nanoliposome
which exhibited appreciable in vitro and in vivo antioxidant efficacy has been
utilized at varying concentrations for fortification of a custard. The designer custard samples
have been characterized for their sensory and physicochemical properties, identification
of the cardamom antioxidants therein and determination of the synergistic efficacy
value of the identified antioxidants.

Results:
The custard formulated with 0.3% nanoliposomes exhibited appreciable antioxidant
potency in terms of DPPH radical scavenging activity (304.58±1.09 mg/ml) and reducing
power (0.020±0.001 mg BHT/g custard), conferred by its total phenolic content
(0.049±0.004 mg GAE/g custard). It also had relatively more stable textural attributes
vis-à-vis the control sample (formulated with the non-encapsulated native extract). GCMS
analysis of the nanoliposome-fortified custard confirmed retention of the spice antioxidants,
namely1,8- cineole, α-terpinyl acetate, α-terpineol and linalool and its synergistic
efficacy value being greater than unity, attested to the synergistic presence of the
said antioxidants therein. The newly formulated custard retained more than 4.5 times of
1,8-cineole (5.05 mg/g custard) vis-à-vis the custard sample (1.12 mg/g custard) prepared
with a microencapsulated (spray-dried) formulation of the extract. Additionally, the
absence of heavy metals in the formulated custard confirmed it to be safe for human consumption.

Conclusion:
This is the first study on the application of nanoliposomes of spiceuticals in
the formulation of a dessert, and more emphatically on use of a ‘green’ supercritical CO2
extract of spice antioxidants in fortification of a dessert to achieve antioxidant synergy.
Sulfated Polyborate, a Novel Buffer for Low pH Mobile Phase on a Nonend Capped Stationary Phase in Reverse Phase Liquid Chromatography
Authors: Sutar Purushottam , Khedkar Pravin , Chaturbhuj Ganesh 
Published: September 2021

Background:
Sulfated Polyborate, a novel inorganic material primarily designed as a catalyst,
has shown properties such as high solubility in organic solvents, low U.V. cut-off, and pKa
≈2.0, which suggests its potential as a mobile phase buffer for reverse-phase liquid chromatography.

Objective:
This study aims to substantiate the role of Sulfated Polyborate as mobile phase buffer
for reverse-phase liquid chromatographic analysis of basic drugs with high pKa values viz. Bisoprolol
fumarate, Timolol maleate, Verapamil hydrochloride, and Carvedilol.

Methods:
Solubilities, U.V. cut-offs, and pKa of Sulfated Polyborate were first experimentally confirmed.
The behaviour of Sulfated Polyborate as mobile phase buffer at pH 3.0 was ascertained by
varying the buffer concentration, flow rates, and percent organic modifier for elution of the four basic
drugs on a non-end capped octyl silyl (C8) column. Similarly, the study was performed with
KH2PO4 as a reference buffer. The column performance and conductometric measurements ascertained
the impact of Sulfated Polyborate on the stationary phase.

Results:
Sulfated Polyborate and KH2PO4 buffers showed correlation coefficients of 0.99 and 1.00
for analyte retention factors for variation of buffer concentration and organic modifier composition,
respectively. Peak symmetries and the number of theoretical plates were improved from > 2.0
to < 2.0 and ≈1000 to ≈3000, respectively, for variation in buffer concentrations. Similar Van
Deemter plots indicated equivalency of Sulfated Polyborate and KH2PO4 buffers. The column performance
and conductometric measurements depicted no adsorption on the stationary phase.

Conclusion:
The present study demonstrates Sulfated Polyborate as a novel buffer for analytes
with higher pKa on reverse-phase liquid chromatography.

Published: September 2021

The discovery of new antibiotics to overcome the growing resistance problem as well as the discovery of new natural, safe antioxidants to combat oxidative stress are still urgently needed. Medicinal plants are known to produce potential therapeutic substances which are more biologically selective than synthetic compounds. Therefore, we explored the bioactivities of 35 ethanolic extracts from 24 underexplored plant species collected in Halmahera, to find potential sources for antibacterial and antioxidant agents.
Dried plant parts were extracted using ethanol 96%. Thin layer chromatography-direct-bioautography (TLC-DB) and minimum inhibitory concentration (MIC) determination were used to evaluate the antibacterial effect. Antioxidant activity was determined against DPPH using TLC-DB and microdilution assay. Total phenolic content (TPC) was determined using Folin-Ciocalteu’s method.
The ethanolic extracts exhibited moderate to weak antibacterial activity against Escherichia coli and Staphylococcus aureus. However, the leaf extract of Elaeocarpus dolichostylus, Elaeocarpus multiflorus, and Psychotria celebica as well as the stem bark extract of Elaeocarpus dolichostylus, Cinnamomum sintoc, and Garcinia latissima displayed very strong antioxidant activities against DPPH with AAI values between 4.60 to 13.42. A strong correlation between TPC and antioxidant activity with r = 0.8712 was observed.
Despite the moderate to weak antibacterial activity, eight underexplored plant species exhibit strong antioxidant activities. A high correlation between TPC and antioxidant activity indicating a prominent role of phenolic compounds in the plants’ antioxidant properties. These findings indicate that collected plants from Halmahera are potential to be studied and developed further as the potential sources for novel antioxidants.

Published: September 2021

Type 2 diabetes mellitus (T2DM) is one of the main non-communicable chronic diseases that has many complications that compromise the quality of life. Hence, the need to find alternatives to replace the current therapy or as an adjuvant. Tubers of Myrmecodia platytytrea (Rubiaceae) has been used traditionally as an alternative therapy for the management of cancer and other inflammatory-related disorders. The aim of this study was to investigate the potency of M. platytytrea methanolic tuber extract (MPMTE) as an antihyperglycemic agent, in vivo. :The streptozotocin (STZ)-induced diabetic rats were treated orally with MPMTE (100, 200 and 400 mg/kg) and metformin (positive control, 100 mg/kg) daily for 14 days. Blood glucose level and other biochemistry analysis were conducted including histological examination on liver, kidney and pancreas. The STZ-induced diabetic rats treated with MPMTE (200 and 400 mg/kg) had significant decreased (p<0.05) in fasting blood glucose, total cholesterol, triglycerides and low-density lipoprotein (LDL) with no significant changes in high-density lipoprotein (HDL) compared to STZ-induced untreated diabetic rats. Liver, kidney and pancreas were devoid of any damage caused by STZ. MPMTE had strong antihyperglycaemic activity and was protective against any STZ-induced organ damage. Thus, MPMTE can be further developed into an adjuvant therapy for diabetic patients.

Published: September 2021

Aim:
To evaluate whether the presence of a history of depression hinders psoriasis response to systemic therapies and to delineate baseline characteristics of patients whose depressive symptoms improved on systemic treatment.
Methods:
We studied patients within the Corrona
®
Psoriasis Registry, a prospective, multicenter observational disease-based registry, that were enrolled through September 2018, comparing changes from enrollment to 12-month visit.
Results:
There was a statistically significant improvement in all disease characteristics and most patient-reported outcomes in patients reporting a history of depression and in those that did not while there was no statistically significant difference in the degree of change comparing these two cohorts. Patients who noted improvement in depressive symptoms had more severe baseline disease characteristics and reported overall worse baseline patient-reported outcomes.
Conclusions:
History of depression does not portend a differential response to systemic treatment. Patients with improvement in depressive symptoms had worse baseline characteristics.

Published: September 2021

Aim:
Postoperative delirium (POD) is associated with increased morbidity and is poorly understood. The aim of this review was to identify putative mechanisms through re-analysis of randomized trials on treatment or prevention of POD.
Materials & methods:
A systematic review was performed to identify systematic reviews of treatments for POD. Constituent randomized controlled trials were identified, and interventions were grouped according to hypothesized mechanisms of action. Effects were meta-analyzed by hypothesized mechanism and timing of intervention.
Results:
A total of 116 randomized controlled trials described 47 individual interventions for POD, with nine mechanisms identified. The largest effects were observed for postoperative inflammation reduction, and preoperative reinforcement of sleep–wake cycle.
Conclusion:
This approach identifies treatments focused on mechanisms of action that may be front runners for future trials and interventions.
EL NIÑO DISLÉXICO Y SU ENTORNO EDUCATIVO. PERCEPCIONES Y REPRESENTACIONES SOBRE LA DISLEXIA
Authors: Antognazza María Paula , González Tornaría María del Luján 
Published: September 2021

Se presenta un estudio sobre las percepciones y representaciones de las familias, docentes, terapeutas y niños sobre la dislexia, en el que se indaga en sus respectivas vivencias y necesidades. Se exponen el diseño y resultados hallados en la investigación de corte cualitativo, basado en las entrevistas realizadas al niño, sus padres, docente y terapeuta. Entre los principales resultados, se destaca que tanto la familia como las instituciones educativas dan una respuesta parcial a las dificultades de aprendizaje y no existe un proyecto integrador que sea estimulante, tanto para el niño disléxico como para su familia. Cuando se logra realizar un tratamiento especializado, los padres no se sienten involucrados. Se detecta ausencia de una visión sistémica de la dificultad, lo que implica pérdida de esfuerzo, energía y tiempo para todas las partes. Se realizan algunas consideraciones respecto a la importancia de pensar especialmente las percepciones de los propios niños disléxicos, colocando tales asuntos en el centro de la orientación diagnóstica y terapéutica.

Authors: Ortega Suárez Walter , Bautista Sánchez Johnny W. 
Published: September 2021

Este artículo brinda un estudio preliminar de la forma de aprovechamiento de la energía del aire comprimido convirtiéndola en energía mecánica rotacional. Para cumplir lo planteado se acondicionó un banco de pruebas con un tanque de almacenamiento para el aire de 0.06 m3, un motor neumático reciprocante de 2 pistones, un dinamómetro con freno electromagnético, un sensor de torque dinámico para determinar la potencia del motor, un sistema de control con PLC para monitorear-controlar el funcionamiento del equipo y un sistema de adquisición de datos que permitió capturar las variables del proceso. Se incluyó un sistema de inyección de aire de tiempo variable controlado electrónicamente a través de un sensor de efecto Hall y un disco de sincronización que traduce la posición lineal del pistón en una posición rotacional. El motor neumático fue construido a partir de un compresor de dos pistones con el que se obtuvo una potencia máxima de 52 W y un torque de 2.5 N.m teniendo en cuenta que la variabilidad del tiempo de inyección influye considerablemente en la salida de potencia. Se obtuvieron eficiencias entre el 7 y 11 % calculadas a partir del concepto de Exergía.
