Southern Exposure: Lived Experiences of the COVID-19 Pandemic
Authors: Johnson, Jr. James H. , Parnell Allan M. , Bonds Jeanne Milliken
Published: December 2021

The COVID-19 pandemic wreaked havoc and disrupted the lives of low-income individuals and families throughout a state in the southeast region of the U.S. Many of the disruptions were shared by all, including isolation-induced mental health issues, adjustments to safety protocols, and financial challenges. Sone lost jobs. Some left jobs to protect family members. Some had major housing issues. Those with school-age children had multiple challenges, including access, reliability, and cost of broadband to support virtual learning; the inability to maintain or return to work because of children at home; and loss of free-and reduced meals at schools. Attitudes about vaccination varied considerably, with some adamantly refusing to be vaccinated, while others acknowledged uncertainty, but hesitatingly sought the vaccines. Others were eager to be vaccinated. Despite personal exposures and familial losses, study participants demonstrated great resiliency, creating ways to keep food on the table, supporting family and friends, finding the positive in having more time with children and other family members, and continuing to search for a way forward throughout the pandemic.

Effect of inert agents on the flammability parameters of selected gases and organic liquid vapours
Authors: Flasińska Paulina
Published: December 2021

Flammable substances may form explosive atmospheres when mixed with air. To prevent their formation or minimise the risk of their occurrence, it is necessary to understand the properties of the mixtures of flammable substances and to apprehend the properties characterising the course of a potential explosion. To minimise the risk of a fire or an explosion, a process called inerting is used in which, e.g. nitrogen plays the role of an inert agent. The article discusses the method for testing the flammability limits, the “bomb” method, in accordance with the European standard PN-EN 1839 and the limiting oxygen concentration (LOC) according to the European standard PN-EN 14756. The study shows the influence of inert gas on the flammability range of selected substances: hydrogen, methane, and hexane, which in practice allows the assessment of the explosion hazard of closed and open spaces, the establishment of safe working conditions, and the selection of equipment operating in given explosion hazard zones. The tests were carried out at 25 °C for hydrogen and methane and at 40 °C for hexane, at ambient pressure.

Dekanter digunakan untuk memisahkan fasa minyak dari sludge underflow continuous settling tank (CST) pada unit klarifikasi di Pabrik Kelapa Sawit (PKS). Jenis dekanter yang umum digunakan di PKS adalah dekanter 3 fasa. Tulisan ini membahas tentang preferensi pemilihan merek dekanter 3 fasa dengan menggunakan metode analisis Analytic Hierarchy Process (AHP). Sebelum dilakukan analisis AHP, koresponden ahli membuat daftar kriteria dan sub-kriteria pemilihan dekanter. Analisis AHP dilakukan tiga tahap, yaitu: i) pengelompokan kriteria, ii) penilaian perbandingan silang kriteria dan sub-kriteria oleh koresponden user, dan iii) penilaian perbandingan kriteria dan sub-kriteria terhadap merek dekanter oleh koresponden user. Analisis AHP menggunakan software Expertchoice® versi 11. Hasil analisis tahap pertama AHP berupa: i) daftar pertanyaan hubungan kriteria dan sub kriteria terhadap merek dekanter yang tersusun dalam kuesioner, dan ii) bobot nilai untuk setiap pertanyaan. Sebanyak 10 orang koresponden user diwawancara untuk menjawab pertanyaan kuisioner. Seluruh data dari kuisioner diinput ke dalam platform analisis. Hasil analisis tahap kedua AHP menunjukkan bahwa kriteria teknis menjadi preferensi utama konsumen dibandingkan kriteria ekonomi. Nilai preferensi tertinggi sub-kriteria ekonomi adalah ketersediaan spare part (KSP), nilai preferensi tertinggi sub-kriteria teknis adalah losis minyak (LM). Hasil analisis tahap ketiga AHP adalah dekanter Merek B berada pada peringkat pertama, dengan nilai preferensi ekonomi 0,148 dan teknis 0,130. Hasil ini menunjukkan bahwa nilai preferensi dapat berubah jika melibatkan analisis yang kompleks antara kriteria, sub-kriteria dan merek dekanter.

Published: December 2021

An oil palm variety with high vitamin E has an added value because of its benefit as pharmaceutical and nutraceutical source. The measurement of the vitamin E content in CPO from eight varieties of oil palm is an effort to obtain high vitamin E varieties with the optimum oil yield. The varieties used in this experiment were DxP PPKS 718, DxP PPKS 239, DxP PPKS 540, DxP Yangambi, DxP Lame, DxP Avros, DxP Simalungun, and DxP Langkat, which were planted in a demonstration block, located at Kebun Adolina PTPN IV. The result showed that the average of the vitamin E from 8 varieties ranged from 477.36 ppm up to 582.78 ppm. The DxP Yangambi has the potency to be improved as the candidate of DxP variety with high vitamin E added value due to its highest vitamin E content. On the other hand, the DxP PPKS 540 is appropriate as candidate of ortets for high vitamin E clones regarding the vitamin E content; which is the highest over the whole samples

Published: December 2021

El análisis de la cadena de valor en bovinos carne de México se ha centrado en la producción y consumidor final, principalmente; sin embargo, los centros de sacrificio representan el eslabón principal entre productores y consumidores. El objetivo fue analizar de la demanda de bovinos carne en pie en los centros de sacrificio de México, 2000-2018. La muestra consideró 50 casas de matanza, en 26 de 32 entidades federativas y los modelos de demanda fueron estimados mediante el método de mínimos cuadrados ordinarios. Fue posible estimar los cuatro mejores modelos de demanda por producto; el precio explicó 43.4 % de la variabilidad en la cantidad de carne de bovino en los centros de sacrificio; 60.4 % para vacas de desecho, 37.7 % novillos, 33.5 % toros de desecho y 28.8 % novillas. Todos los productos se comportaron inelásticos al precio (-0.17), pero la demanda de novillos tuvo la menor elasticidad (-0.06). El mercado de la carne de bovino presentó una baja densidad media de las conexiones entre productores y centros de sacrificio analizados (25.2 ± 43.4 %), que indica una ineficiencia del mismo. El estado de Jalisco representó el principal centro de sacrificio en novillos y vacas de desecho, mientras que Aguascalientes en novillas y toros de desecho.
The Effect of Obesity on Musculosceletal System
Authors: Knap V. , Ondova P. , Istonova M. , Oravcova K.
Published: December 2021

Obesity arises and persists during an excessive long-term pos- itive energy balance. Risk factors for the development of obe- sity are, in particular: ahigh-calorie diet, low physical activity; adaptation to asedentary lifestyle; irregular diet. The most commonly used criterion for assessing obesity is the Body Mass Index – BMI. The incidence of obesity in Europe is be- tween 10% to 25% in women, while more than 50% of the pop- ulation in most European countries is overweight and obese. The effect of obesity on the musculoskeletal system is demon- strable in patients who suffer its consequences during their life. Long-term overweight is the cause of excessive strain on bones, joints and muscles, which over time, due to the chronic course of obesity, affects almost every obese individual. Obesity prevention programs, the development of a healthy lifestyle, healthy eating and exercise-related activities are our common goals for preventing obesity.
Influencia de la altitud sobre la composición florística, estructura y carbono de bosques del Chocó
Authors: Jhon Jerley Torres Torres Jhon Jerley Torres Torres
Published: December 2021

Introducción: A pesar de la amplia diversidad sugerida para el Chocó, a la fecha es poco lo que se ha documentado sobre la influencia de la altitud en la composición florística, estructura, diversidad, biomasa y carbono arbóreo. Objetivo: evaluar la influencia de la altitud sobre la composición florística, estructura y carbono almacenado en bosques del gradiente altitudinal Quibdó-Carmen de Atrato en el Chocó biogeográfico. Métodos: se establecieron 18 parcelas (20×20 m) distribuidas en un gradiente de 100–1700 m de altitud comprendida entre Quibdó y Carmen de Atrato, Chocó. Se identificaron todas las especies y se contabilizaron todos los individuos. La composición florística fue analizada mediante el método de Ward. Se realizó una regresión lineal simple para observar la relación entre la altitud y las variables estructurales y de biomasa. La diversidad fue estimada a través de los índices de Shannon y Simpson. Se calculó la biomasa empleando una ecuación alométrica desarrollada para este tipo de bosque. El carbono fue estimado con una fracción de carbono de 0,5.    Resultados: Se registró un total de 33 familias botánicas, 90 especies y 773 individuos. Los sitios de menor altitud presentaron mayor riqueza. Las familias con mayor número de especies arbóreas fueron: Fabaceae, Malvaceae, Lauraceae y Clusiaceae. El análisis de Ward permitió separar a los sitios en dos grupos diferentes estadísticamente (p ˂ 0,05), el primero de menor altitud dominado por las especies Pouteria amygdalicarpa, Iryanthera tricornis Ducke, Brosimum utile (Kunth) Pittier. y Pithecellobium sp. y el segundo de mayor altitud dominado por Aniba puchury-minor (Mart.) Mez. A nivel de densidad se destacan pocas diferencias entre los sitios muestreados, mientras que para el área basal se aprecia que su valor disminuye conforme aumenta la altitud. Para las variables riqueza de especie, área basal, diversidad y biomasa se obtuvieron relaciones y correlaciones negativas con la altitud, mientras que para la densidad esta fue positiva. En promedio se obtuvo un carbono almacenado en la biomasa aérea de 68,28 Mg h-1 para el gradiente altitudinal Quibdó – Carmen de Atrato, el cual disminuye conforme aumenta la altitud y difiere estadísticamente entre los sitios muestreados (p ˂ 0,05). Conclusión: Se evidencia que la altitud ejerce una fuerte influencia negativa en la composición florística (riqueza de especie y recambio florístico), la estructura (área basal e Índice de Valor de Importancia) biomasa y carbono de los ecosistemas estudiados.
Postcolonial Gothic Elements in Joaquin’s The Woman Who Had Two Navels
Authors: Abedi Valoojerdi Mohammad Hossein
Published: December 2021

Nick Joaquin (Nicomedes Márquez Joaquín, (1917-2004) is known for his unique style of writing, tropical Gothic, and applying gothic elements in his stories and novels. This paper examines his first novel The Woman Who Had Two Navels through the lens of postcolonial theory. The paper also investigates gothic narratives in his novel by applying David Punter’s literary-historical approach. Punter (2000), in his book Postcolonial Imaginings: Fictions of a New World Order, examines the metamorphoses of the Gothic as a genre in some selected novels and poems. The book depicts new manifestations of the Gothic during 20th century literature. This paper attempts to investigate how the elements of postcolonial Gothic as discussed by Punter are manifested in Joaquin’s novel. In doing so, the contrapuntal method of reading, introduced by Edward Said (1993), is also applied to explore the hidden parts of history in the novel.
Negotiating Cultural Identity in The Inheritance of Loss
Authors: Deng Chiou-Rung
Published: December 2021

This paper seeks to explore three modes of cultural identification presented in Kiran Desai’s The Inheritance of Loss. With three intersecting plotlines, the novel focuses on three divergent modes of cultural identification in different spatio-temporal contexts. The first kind of cultural identification is imbued with a sense of foreignness, exemplified by the judge, Jemubhai, whose cultural identity is deeply shaped by imperialist ideology during British colonization of India. As Indian culture is negated by the colonial power, Jemubhai adheres to English cultural identification and disavows his Indianness. The second mode of cultural identification revolves around the issue of cultural authenticity in the diasporic context for Biju, a young migrant, illegal worker in various restaurants in New York. To survive in a foreign country, Biju forces himself to transgress cultural borders, which disconcerts Biju and further prompts him to pursue cultural authenticity. The third mode highlights Sai’s and Gyan’s trajectories of cultural identification. Just as Sai, Jemubhai’s granddaughter, embodies the idea of in-betweenness, Gyan, Sai’s math tutor, manifests the desire to escape narrow nationalism. Both Sai and Gyan evoke the potential of crossing borders. Juxtaposing the three modes of cultural identification, Desai’s novel explores the process of negotiating cultural identity and gestures towards a field of border-crossing identity.
Who wins the tug of war? A comparative study of the influence of board power and CEO power on CEO-TMT pay gap
Authors: Wang Zhonghui , Li Zonghui
Published: December 2021

Extant studies theoretically debate and empirically present inconsistent findings of the factors that influence the CEO-TMT pay gap. In this study, we extend the research of the antecedents of the CEO-TMT pay gap by directly comparing different theoretical predictions regarding the impacts of board power and CEO power on the CEO-TMT pay gap. Conducting dynamic panel analyses with GMM estimator on a sample of 2,117 firm-year observations in the S&P 500 between 2006 and 2013, we empirically test the contrasting predictions regarding the relationships among board power, CEO power, board-CEO power imbalance, and the CEO-TMT pay gap. In turn, we find that board power is negatively associated with the CEO-TMT pay gap and CEO power has the opposite effect. Moreover, the stronger board power against CEO power, the smaller the CEO-TMT pay gap becomes. Our theoretical analyses and empirical investigations contribute to the existing theoretical debate among agency theory, tournament theory, and managerial power theory regarding the determinants of the CEO-TMT pay gap. Consistent with agency theory predictions rather than tournament theory ones, our empirical results suggest that boards are conscientious about the potential negative effects of a larger CEO-TMT pay gap and therefore stronger boards usually do not rely on larger CEO-TMT pay gap to incentivize CEOs. This study also contributes to corporate governance literature by offering new aggregated proxies for board power and CEO power which reflect the multidimensional features of board-CEO relationships

Should Routine Pulmonary Function Tests be Performed in Patients with Left Ventricular Dysfunction and/or Congestive Heart Failure undergoing Cardiac Surgery?
Authors: Albacker Turki , Alhothali Abdulaziz , Arafat Amr , Algarni Khaled , Eldemerdash Ahmed , Bakir Bakir
Published: December 2021

Background It is controversial whether pulmonary function
testing should be performed routinely in cardiac surgery patients. The
aim of our study was to focus on patients who have congestive heart
failure, caused by left ventricular dysfunction or left-sided heart
valve disease, and study the prognostic value of performing preoperative
pulmonary function testing on their postoperative outcomes
Methods: This is a retrospective propensity score matched study
that included 366 patients with congestive heart failure who underwent
cardiac surgery and had preoperative pulmonary function test. The
patients were divided into two groups: Group 1; who had a normal or mild
reduction in pulmonary function tests and group 2; who had moderate to
severe reduction in pulmonary function tests. The postoperative
outcomes, including pulmonary complications, were compared between the
two groups. Results Pulmonary function tests were normal or
mildly reduced in 190 patients (group 1) and moderately to severely
reduced in 176 patients (group 2). Propensity matching identified 111
matched pairs in each group with balanced preoperative and operative
characteristics. Compared to group 1, Group 2 had longer duration of
mechanical ventilation [12 (7.5- 16) vs. 9 (6.5- 13) hours,
p<0.001], higher postoperative Creatinine [111 (90- 142)
vs. 105 (81- 128) µmol/dl, p=0.02] and higher hospital mortality
(6.31% vs 0%, p=0.02). Conclusion In congestive heart failure
patients undergoing cardiac surgery, moderate to severe reduction of
pulmonary function test was associated with longer duration of
mechanical ventilation and higher hospital mortality.

Published: December 2021

Este manuscrito tiene como objetivo determinar la influen- cia del valor de marca en las intenciones de recompra de unproducto de tal forma que contribuya en la perdurabilidad empresarial. El estudio se apoya en los conceptos generales del valor de marca con sus dimensiones: lealtad, notoriedad, calidad percibida, asociaciones y comportamiento del mer- cado. El estudio empírico utiliza un enfoque cuantitativo en el que se procesan los datos procedentes de 321 encuestas. Se analizan los resultados de las correlaciones entre las di- mensiones del valor de marca con la variable dependienteintención de recompra. Los resultados sugieren que existe una relación positiva, pero con un valor estadístico medio, lo que indica que estas dos variables están significativamen- te relacionadas. Los datos revelan que la dimensión quepresenta una relación mas alta es la correspondiente a las asociaciones, por el contrario, la variable con menor rela- ción es la lealtad. Se concluye que el conocimiento de las percepciones de los consumidores sobre las marcas, permi- te la adopción de medidas conducentes a la perdurabilidad empresarial en el largo plazo.
Numerical simulation considering the effect of uneven frost heave on tunnel structure in cold regions
Authors: Li Ning , Liu Zhi-Qiang , Niu Guo-Dong , Zhang Jian , Li Jun-Ping , Zhang Fan
Published: December 2021

Freezing damage is one of the main diseases of tunnels in cold regions. Water
storage behind the lining is a necessary condition for freezing damage.
Compared with the previous condition of uniform water storage behind the
lining, this paper explores the influence of water storage and frost heave
at different positions on tunnel structure in cold regions. Based on the
theory of thermo-hydro-mechan?ical coupling. The finite element model of
tunnel surrounding rock in cold area under different positions and different
water content is established and compared by using COMSOL software, the
mechanical characteristics of tunnel lining under different water storage
positions behind the lining are studied, and the influence of frost heave at
different positions on tunnel structure is explored. The numerical
simulation results show that no matter where the local water storage area is
lo?cated, the area with the largest frost heave force is located in the
lining structure, close to the surrounding rock. Different local water
storage positions will also have different influences on the tunnel
structure. In the same water storage area, the frost heave force will
increase with the decrease of temperature.
Characteristics and optimization of SCO2 Brayton cycle system for high power sodium-cooled fast reactor on Mars
Authors: Zhang Hao-Chun , Liu Xiu-Ting , Liu Jin , Li Zeng-En
Published: December 2021

Mars is the target of deep space exploration. The first problem of landing on
Mars and building a satellite base is the energy source. For more than 50 kW
high power demand, space nuclear energy system has the advantages of high
output power, large energy density, small area, short working time and so
on. Super-critical CO2 Brayton cycle with sodium cooled fast reactor is the
most promising power solution because of the high energy conversion
efficiency. The thermodynamic model of super-critical CO2 Brayton cycle
system with sodium cooled fast reactor as the heat source has been
established. After the analysis of circulation process, the relationship
between temperature, pressure and enthalpy at working point has been
discussed, and the relationship of circulation efficiency has been deduced.
The real gas model is used to correct the thermophysical properties of
super-critical CO2. The thermal efficiency of the system is analyzed under
the typical working condition of Mars surface. What?s more, the effects of
pressure ratio, compressor inlet temperature, turbine inlet temperature, and
the temperature ratio on the cycle efficiency are discussed to get the
optimal cycle characteristic and condition parameters.
Characteristics of perch fish diet in small lake of Lake Onega catchment area
Authors: Georgiev Andrey Pavlovich , Legun Anna Grigorievna , Pogosyan Valeria Rubenovna
Published: December 2021

Fish feeding process is studied as one of the links in the transformation of the energy of a water reservoir, as one of the factors that determine the ecology of fish and make an imprint on the morphology, physiology and behavior of fish, or as one of the criteria, which help the most rationally use natural resources of the water bodies. The results of work carried out by the Northern Water Problems Institute (NWPI KarRC RAS) and Petrozavodsk State University (PetrSU) within the framework of state assignments, forecast problems and economic contractual topics on assessing the nutrition of perch species (perch, ruff) in some lakes of the Konchezero group (South Karelia), in particular Lake Munozero, which is part of the lower reaches of the river Shuya belonging to the catchment area of Lake Onega. The work was carried out by the experts from the IWPS KarRC RAS and PetrSU in 2018-2020. Its main hydrological and ichthyological indicators have been studied. The reconnaissance fish productivity of Lake Munozero based on the development of the forage base at the present stage is estimated as 9 kg/ha. The feeding spectra of ruff and perch in the lake overlap only with respect to eggs, the ruff using eggs more actively. Predation is peculiar only to perch, while even fish whose size is less than 14 cm (the average size of the transition to predation for Karelia) hunt at a time when there is a lot of other food in the reservoir. As the perch passes to summer feeding, its diet becomes more diverse. Some benthic organisms are replaced by others, an air fraction appears, the perch's diet includes fish in summer and spring; nutrition becomes more active: the average stomach fullness index increases from 7.3 to 145.6‰.

The objective of the research was to know the optimal length time of bali beef aging in order to produce the best quality of its organoleptic. Analyses used was Non Parametric Kruskal Wallis. If the results significantly different, it will be continued to Mann Whitney analyses. Treatments used were fresh beef without aging (P0), aging beef for 6 hours (P1), aging beef for 8 hours (P2) and aging beef for 10 hours (P3) on the same room temperature (28-29oC). Results showed that beef texture score decreased significantly different (P<0.05) from P0 to P3. The highest beef aromatic and colour of P0 significantly different (P<0.05) compare to the P1, P2, and P3. The tenderness of the P3 was the highest with score for 3.92 and significantly different (P< 0.05) than the P0, P1 and P2. The highest taste was the P2 with score for 3.46 significant different (P<0.05) than the P0, P1 and P3. The highest score of the beef acceptance totally was 4.08 of P1 significantly different (P<0.05) compare to the P0, P2, and P3. It can be concluded that the length time of bali beef aging could affect beef organoleptic and the optimal time to produce the best quality organoleptic of the beef is 6 hours.

Este artículo aborda dos casos de comunidades urbanas vecinas de proyectos mineros en el municipio de Soacha y tiene como objetivo principal comprender cómo surge la movilización frente a la minería en comunidades urbanas que son vecinas de estos proyectos. Por esa razón, se compara un caso en el que se presentó un ejercicio de movilización con uno en el que esta no ha ocurrido. Estos casos comparten el hecho de ser vecinos del distrito minero del municipio, tienen una composición socioeconómica similar y, en ambos, se ha analizado la misma temporalidad usando el método comparativo cualitativo con información obtenida a partir de documentos y entrevistas. Se han encontrado dos factores explicativos sobre el surgimiento de la movilización: por un lado, la existencia de una administración que constituye oportunidades políticas que son percibidas como tales. Por otro, la apropiación de espacios organizativos institucionalizados aparejada con alianzas organizativas.
Sono e ritmos circadianos na depressão resistente
Authors: Filho Dirceu Zorzetto
Published: December 2021

Os distúrbios do sono e do ritmo circadiano constituem características essenciais dos quadros depressivos. As alterações do ciclo vigília-sono são frequentemente sintomas prodrômicos dos transtornos depressivos e desempenham um papel na patofisiologia dos transtornos do humor. Essas alterações predizem um novo episódio, aumentam o risco de recaída e de recorrência e correlacionam com maior risco de suicídio. A permanência de transtornos de sono pode aumentar a refratariedade ao tratamento. Os pacientes com depressões resistentes ao tratamento farmacológico apresentam uma importante desregulação circadiana e diminuição da amplitude do ritmo delta durante o sono. Os tratamentos disponíveis para os distúrbios do sono na depressão resistente incluem medicações com efeitos hipnóticos e intervenções não farmacológicas. Drogas como os agonistas de receptores benzodiazepínicos, agonistas melatoninérgicos e antagonistas dos receptores serotonérgicos do tipo 2C têm demonstrado eficácia na regularização das alterações do sono em pacientes com depressão. Intervenções não farmacológicas como a terapia cognitivo-comportamental e a fototerapia também são úteis, particularmente quando associadas à medicação antidepressiva.
MODELLING OF ROBOT MANIPULATION IN INTEGRATED PRODUCTION
Authors: Rudolf Jánoš
Published: December 2021

Urgency of the research. Cell production has become one of the most important studies of the arrangement of production systems. This production philosophy is based on the fact that the products are similar in shape and production processes. This allows parts to be grouped into groups that they share during their processing, ensuring an economic effect.Target setting. Automated production systems are built with large investments. The result is small-scale production automation cells, including industrial robots, including handling automation. These automation islands did not meet expectations in terms of costs, commissioning dates, meeting production deadlines, achieving planned performances, so attention must be paid to integrated production. Actual scientific researches and issues analysis. Integrated production reduces material handling and transport time. By making the product more time on the machinery and less time on the road. Because the parts move in the chamber and not in the entire factory, travel time and distance are reduced, leading to a reduction in material handling costs, which represents between 20 and 50 % of the total operating costs. Uninvestigated parts of general matters defining. Most articles and other publications on the problem of modeling integrated manufacturing alleviate the problem of modeling a specific cell. In my article I will solve a production cell in general without specific properties. The research objective This paper focuses on the integrated and logistic of the style of material flow, suitable for realization manufacturing and logistics network. Solution base is defining of mission, objectives and goal integrated of the style of material flow. The core of solution is analysis of strategy on integrated. The result of solution is to define tools integrated and formation evolution profile of the style of material flow. The statement of basic materials.In general, the key to building integrated production is group technology based on the principle of material flow analysis. The problem of modeling integrated production points to possible variants of solutions based on the analysis of material flows. However, considering only this criterion is insufficient for practice, because it does not consider e.g. about the number of pieces. Conclusions. These relationships are representative of some approaching the importance of parameterization, which remains open and accessible to address other tasks to optimize the production system.

En torno al prólogo y las notas de la traducción al español del Codex, Pharmacopée française de 1837
Authors:   Universidad de Córdoba (España), Álvarez Jurado Manuela
Published: December 2021

Pharmacopeias or Codex arise from the necessity of establishing a text which contains some reference rules which may guarantee the safety and the usefulness of pharmaceutical products. The significant advancements which took place in the fields of Chemistry and Pharmacy during the nineteenth-century led to an update of these works, in order to include the preparations which had recently been formulated. Forty-eight years passed between the fourth edition of the Pharmacopoea Hispana and the next one, published in 1865. Thus, during all this period there was an absence of an official pharmacopeia. Consequently, Manuel Jiménez decided to translate the 1837 Pharmacopée française. This paper analyzes the paratextual instances of this translation, specifically the prologue and the translator's notes, where the translator becomes visible and acts as a mediator between two different cultures.
Symmetric RAFT-agent for synthesizing multiblock copolymers with different activated monomers
Authors: Petrozziello Lena , Häußler Matthias , Kayser Christoph , Klapper Markus
Published: December 2021

With a bifunctional symmetric RAFT agent well-defined polymer structures can be achieved. This paper shows the possibility to synthesize block copolymer systems consisting out of different activated monomers. With the novel bifunctional symmetric RAFT agent water-born polymer systems with a block structure (B-b-A-b-B) can be polymerized. The symmetric RAFT agent is designed to polymerize both more activated monomers (A) and less activated monomers (B). Due to the ability of a controlled radical polymerization of different activated monomers the dispersity of the resulting polymers is broader compared to common RAFT polymerizations. In regard to industrial applications like emulsifiers, stabilizers or viscosity modifiers the broader molecular weight distribution has no impact. Overall, this paper shows the possibility towards new functional polymers with unique properties.

Linear free energy relationship (LFER) plots are constructed for the deprotonation equilibriums (pKaH+) of pyrazolium and indazolium (benzopyrazolium) cations. The reaction constants Taft * and Hammett  are found to be 2.75 and 1.32 for deprotonation (pKaH+) of pyrazolium and indazolium cations respectively. Higher value of Taft * than the Hammett  is explained in terms of extra stability of the indazolium cation due to its greater number of resonance structures. This article is an exercise to undergraduate students for writing different resonance structures of indazolium cation.

Published: December 2021

Redox-active organic molecules are promising charge-storage materials for redox-flow batteries (RFBs), but material crossover between posolyte/negolyte and chemical degradation are limiting factors in the performance of all-organic RFBs. We demonstrate that the bipolar electrochemistry of 1,2,4-benzotriazin-4-yl (Blatter) radicals allows construction of batteries with symmetric electrolyte composition. Cyclic voltammetry shows that these radicals retain reversible bipolar electrochemistry also in the presence of water. The redox potentials of derivatives with a C(3)-CF3 substituent are least affected by water and, moreover, these compounds show >90% capacity retention after charge/discharge cycling in a static H-cell for seven days (ca. 100 cycles). Testing these materials in a flow regime at 0.1 M concentration of active material confirmed the high cycling stability under conditions relevant for RFB operation, and demonstrated that polarity inversion in a symmetric flow battery may be used to rebalance the cell. Chemical synthesis provides insight in the nature of the charged species by spectroscopy and (for the oxidized state) X-ray crystallography. The stability of these compounds in all three states of charge highlights the potential for application in symmetric organic redox-flow batteries.
