Upaństwowienie przedszkoli żydowskich w Polsce „ludowej”
Authors: Wiśniewska Monika
Published: December 2020

Educational and teacher training institutions for Jewish children and adolescents had a long and well-established tradition in Poland. Institutional forms of preschool education call for special attention, all the more so that the remaining national and ethnic minorities did not run their own kindergartens in Poland after WWII. In these circumstances, Jewish kindergartens were a striking exception. Ultimately, they suffered the same fate as the other educational and teacher training institutions managed by entities not welcomed by the Communist party and government in Poland, inspired by Marx’s and Lenin’s ideologies, whose guidelines from the communist headquarters in Moscow imposed a monopolistic vision of so-called socialist education and upbringing.
“From phenomenon, throughout the fact, to foundation”. Outline of the concept of man and its development according to Edith Stein (1891–1942)
Authors: Chrost Sławomir
Published: December 2020

Edyta Stein – Sister Teresa Benedicta of the Cross – was fascinated by the “mystery of man”. Discovering this mystery led her to experience the “mystery of God”. She had a beautiful and difficult road leading through life and scientific transgressions, the path from thanatology to transthanatology, from the existence of a contingent existence to the existence of eternal Being. According to Edith Stein, the existence of man is unique. Everyone has to discover the fullness of his existence. Here comes Stein’s transition from psychological and philosophical considerations (phenomenon-fact) to theological considerations (foundation). By learning about God, man recognizes himself and discovers the ultimate truth of his existence. Whoever does not reach himself will not find God and enter eternal life. Or better: whoever does not find God will not find himself (no matter how much focus he will give on finding himself) and the source of eternal life that awaits him in his own interior.
Profesor Tadeusz Sulimirski, współorganizator szkolnictwa polskiego na uchodźstwie w latach 1941–1947
Authors: Chmielewski Witold
Published: December 2020

The aim of the article is to present the achievements of Professor Tadeusz Sulimirski, an archaeologist, in reference to organising and managing Polish education in exile, 1941–1947. The biographical method prevails in this research paper, presenting one of the leading figures in the Office of Education and School Affairs, as well as the Ministry of Religious Denominations and Public Enlightenment of the Polish government in exile. Tadeusz Sulimirski launched numerous initiatives aimed at developing and streamlining all the forms of Polish education in exile. He cooperated very closely with General Józef Haller. He devoted much attention to developing Polish higher education in exile. Once the Polish government in London was no longer recognised by the British government, Professor Tadeusz Sulimirski became head of the Department of Education, formed on 7 July 1945, of The Interim Treasury Committee for Polish Questions established by the British. He demonstrated great creativity and organizational skills, while very competently coordinating the gradual discontinuation of Polish education in Great Britain and, to some extent, in some of the British dominions. He took great care of the financial situation of Polish students in Great Britain and in the Middle East. He also received students and schools from General Władysław Anders’ Polish II Corps evacuated from Italy to Great Britain. In the post-war years he was an active member of Polish academic circles. He greatly contributed to the development of Polish education in exile and to establishing Polish identity among war refugees.

Diffractive optics based automotive lighting system
Authors: Khan Muhammad Shaukat , Saeed Woheeb Muhammad , Roth Bernhard , Lachmayer Roland
Published: December 2020

Information projection using laser-based illumination systems in the automotive area is of keen interest to enhance communication between road users. Numerous work on laser-based front end projection employing refractive and reflective optics has been reported so far, while for rear end illumination efforts are more scarce and a different optical design concept due to limited volumetric size and field of view regulations is required. Here, we report on a new and versatile approach for a laser-based rear end lighting system for automotive application which enables projection of information or signals to support other road users. The design is based on thin diffractive optical elements projecting the desired patterns upon illumination. Also, for protection of the road users from the steering laser beam, a diffusive back projection screen is designed to project information while fulfilling both the field of view and safety requirements. The projection system is based on a periodic diffusive structure made of an array of biconic lenses with sizes in the millimeter range. The field of view (FOV) from the simulated lens arrays complies with the angular requirements set by the Economic Commission for Europe (ECE). As a proof of concept, the diffusive screen is fabricated using microfabrication technology and characterized. In future, the screen will be combined with thin diffractive optical elements to realize an entire integrated projection system.
On the mutation model used in the fingerprinting DNA
Authors: Krajka Andrzej , Panasiuk Ireneusz , Misiura Adam , Wójcik Grzegorz M.
Published: December 2020

Objectives

The most common technique of determining biological paternity or another relationship among people are the investigations of DNA polymorphism called Fingerprinting DNA. The key concept of these investigations is the statistical analysis, which leads to obtain the likelihood ratio (LR), sometimes called the paternity index.

Methods

Among the different assumptions stated in these computations is a mutation model (this model is used for all the computations).

Results and conclusions

Although its influence on LR is usually negligible, there are some situations (when the mother–child mutation arises) when it is crucial.
Personality Traits and Household Consumption Choices
Authors: Mangiavacchi Lucia , Piccoli Luca , Rapallini Chiara
Published: December 2020

This study examines the role personality traits play in influencing consumption decisions for both individuals and households by means of a complete system of Engel curves. Estimations are performed on the German Socio-Economic Panel (SOEP) using the following four different samples: single men, single women, childless couples and couples with children. Personality traits are found to moderately improve the general goodness of fit of the model, reducing the RMSE on average by 2.8%. This is the result of some traits strongly contributing to explaining specific consumption categories, such as Mental Openness contributing substantially to explaining expenditure in education and culture, and several non-significant personality trait-consumption category associations. Robustness analysis suggests that the effect is fairly stable across age groups within the same household type and that the effects of personality traits on consumption choices are independent of education level.
Public Health Insurance and Impacts on Crime Incidences and Mental Health
Authors: Wagner Kathryn L.
Published: December 2020

This paper evaluates the effect of Medicaid expansions for individuals with disabilities on crime rates and mental health status. Using the FBI’s Uniform Crime Reports and the CDC’s Behavioral Risk Factor Surveillance System Surveys, I estimate the impact of Medicaid using an event study approach. Results indicate a reduction in crime incidence that was strongest in the years immediately following the expansion and dissipated over time. Estimates also suggest a smaller likelihood of one day of poor mental health within the past month, but this impact was short-lived. Analysis suggests that improved alcohol abuse was not a main explanation for mental health improvements. The analysis cannot eliminate whether improvements to non-alcohol substance abuse treatment, financial strain, or access to treatment for other mental illnesses explain the impact to crime and mental health status. Expanding Medicaid shows a degree of impact on both crime and mental health suggesting several policy considerations.
The Italian External Quality Assessment (EQA) program on urinary sediment by microscopy examination: a 20 years journey
Authors: Secchiero Sandra , Fogazzi Giovanni B. , Manoni Fabio , Epifani MariaGrazia , Plebani Mario
Published: December 2020

Objectives

In spite of the introduction of automated systems for urinary sediment analysis, microscopy examination remains the gold standard, and it is more than ever important to perform it with a good and reliable quality. External Quality Assessment (EQA) programs on urinary sediment are rare. The present paper provides an analysis of results from 2001 to date of the EQA Italian program which involves today 230 laboratories.

Methods

The program includes four surveys per year. Participants are asked the identification and clinical associations of urinary sediment particles, shown as phase contrast microscopy images in the website of the Center of Biomedical Research (CRB) (2 surveys), and the diagnosis of clinical cases presented by both images and a short clinical history (2 surveys). The results of each survey are then scored and commented. In 20 years, 298 images were presented: 90 cells (9 types), 23 lipids (5 types), 87 casts (21 types), 53 crystals (14 types), 22 microorganisms (5 types), and 23 contaminants (9 types). Moreover, 27 clinical cases, covering a wide spectrum of conditions with different degrees of complexity, were presented to participants.

Results

Identification: among urinary particle categories, the correct identification rate (obtained for each particle from the sum of correct + partially correct answers) was very high for micro-organisms (mean ± SD: 96.2 ± 3.5%), high for lipids (88.0 ± 11.8%) and crystals (87.0 ± 16.5%) followed, in decreasing order, by cells (82.1 ± 15.9%), casts (81.8 ± 14.8%), and contaminants (76.7 ± 22.1%). Clinical associations (n=67): the rate of correct answers was 93.5 ± 5.7% ranging from 75.0 to 100% for all but one clinical association (i.e., acute glomerulonephritis: 55.4%). Clinical cases: throughout surveys, due to the overall rate of particle misidentification, only 59.8 ± 17.1%, (range 32.5–88.7%) of participants achieved access to clinical diagnosis. Of these, 88.7 ± 10.6% (range 59.9–99.3%) were able to indicate the correct diagnosis.

Conclusions

Our program can be used as a tool to improve the identification of urine particles and the knowledge of their clinical meaning and to encourage specialists of laboratory medicine to correlate urinary findings with other laboratory data and the clinical history, an aspect that improves the value of the day by day work.
The Good-Faith Purchase Doctrine in 247 Jurisdictions
Authors: Chang Yun-chien
Published: December 2020

Scholars have argued that reasonable persons can disagree on what the most sensible good-faith purchase doctrine is. Indeed, using hand-coded data on this doctrine in 247 jurisdictions, this article finds that this doctrine has hardly converged-there are at least 23 different variants of this doctrine, from “no good faith required” to “good faith is all the purchaser needs.” The 23 variants can be grouped into three clusters: the categorical approach, under which stolen goods always revert back to original owners; the binary approach, under which the distinction between stolen and non-stolen goods matters, but stolen goods do not always revert; and the unitary approach, under which there is no distinction between stolen and non-stolen goods.
Aptian–Albian deposits of the Ait Ourir basin (High Atlas, Morocco): New additional data on their paleoenvironment, sedimentology, and palaeogeography

Published: December 2020

This sedimentological and palaeontological analysis of the Aptian–Albian sedimentary succession of the Ait Ourir basin in the High Atlas Mountains of Marrakesh in Morocco provides new data from a previously poorly understood basin. The palaeoenvironmental evolution is deduced based on a facies analysis allowing the restoring of depositional environments and their stratigraphic architecture. Within the Aptian–Albian succession, we distinguish two sedimentary sequences separated by a major discontinuity. The first sequence is composed of calcareous and dolomitic marls with the rudistPseudotoucasia catalaunicaof the Tadhart formation (upper Aptian in age) and of strongly dolomitized limestones with corals (Eugyrasp.,Thalamocaeniopsissp., andHolocystissp.) of the Lemgo formation (uppermost Aptian in age). These two formations were formed in an internal carbonate platform (the intertidal zone to the subtidal zone). The second sequence, Albian in age, is composed of sandy limestones of the Oued Tidzi formation and is represented by sediments showing terrigenous influence, with deposits of silt, sandstone, dolomitic sandstone, and limestone.

Published: December 2020

The present study explores the potential of Valeriana jatamansi shoot extract for Ag-metal bio-reduction and its antimicrobial activity. Among the different ratios of AgNO3 and extract tested, 1:5 (1 mL AgNO3 and 5 mL extract) gave maximum SPR peak at 411.0 nm during UV-Vis spectrophotometric analysis, indicating the synthesis of maximum amount of AgNPs in solution. XRD analysis reported the crystalline nature of AgNPs with 13.32 nm nanocrystallite size. FTIR studies suggested the involvement of carboxylic acid (–[C–O–O–H]) and methane (–CH–) functional groups of different compounds in AgNPs reduction and fabrication. Average size of synthesized uniform shaped nanospheres was 32 nm by SEM image analysis. The produced AgNPs (1.5 mg/disc) showed growth inhibition of 71.46, 65.97, 61.5, 55.32, and 54.83% against Pseudomonas aeruginosa, Escherichia coli, Candida albicans, Xanthomonas campestris, and Staphylococcus aureus. While the least growth inhibition of 48.55% was recorded for Klebsiella pneumonia, suggesting it as the least-susceptible microbe among all the tested microbial species. P. aeruginosa was found to be most sensitive of all tested microbes, while E. coli, C. albicans, and X. campestris reported moderate susceptibility to AgNPs.

The present study was aimed to biosynthesize selenium nanoparticles (SeNPs) and assess their foliar applications to improve the growth of wheat plants under controlled irrigation and drought stress. Bud aqueous extract ofAllium sativumL. was used as a reducing and stabilizing agent of SeNPs followed by their optical and morphological characterization by using ultraviolet-visible spectroscopy, scanning electron microscopy, Fourier-transform infrared, and energy dispersive X-ray analysis. Various concentrations of SeNPs (10, 20, 30, and 40 mg/L) were applied exogenously to drought-tolerant (V1) and drought-susceptible (V2) wheat varieties at the trifoliate stage. Under the positive control conditions, plants were irrigated with 450 mL of water/pot (100% field capacity); and under water-deficit environment, plants were irrigated with 160 mL of water/pot (35% field capacity). Remarkable increase in plant height, shoot length, shoot fresh weight, shoot dry weight, root length, root fresh weight, root dry weight, leaf area, leaf number, and leaf length has been observed when 30 mg/L concentration of SeNPs was used. However, the plant morphological parameters decreased gradually at higher concentrations (40 mg/L) in both selected wheat varieties. Therefore, 30 mg/L concentration of SeNPs was found most preferable to enhance the growth of selected wheat varieties under normal and water-deficient conditions.
Recasting Ethics of Face and Hiya (Shame) in the Light of Cybersexual Violence Against Women
Authors: Brazal Agnes M.
Published: December 2020

This paper explores how Philippine/East Asian discourses on ethics of face and shame can be relevant in light of cyber-sexual violence against women. It argues that lowland Philippine concept of hiya (shame) in its moral and internal sense, should be retrieved as virtue in the context of cyber-sexual violence against women. This can however be complemented by Emmanuel Levinas’ concept of the face of the Other and its reception especially in the cyber-context. Hiya (shame) as sensitivity to a loss of face of the excluded kapwa (other), leads to actions that not only helps to “gain face” but also reveal the God who enfaces.
Temporal-based intrusion detection for IoV
Authors: Hamad Mohammad , Hammadeh Zain A. H. , Saidi Selma , Prevelakis Vassilis
Published: December 2020

The Internet of Vehicle (IoV) is an extension of Vehicle-to-Vehicle (V2V) communication that can improve vehicles’ fully autonomous driving capabilities. However, these communications are vulnerable to many attacks. Therefore, it is critical to provide run-time mechanisms to detect malware and stop the attackers before they manage to gain a foothold in the system. Anomaly-based detection techniques are convenient and capable of detecting off-nominal behavior by the component caused by zero-day attacks. One significant critical aspect when using anomaly-based techniques is ensuring the correct definition of the observed component’s normal behavior. In this paper, we propose using the task’s temporal specification as a baseline to define its normal behavior and identify temporal thresholds that give the system the ability to predict malicious tasks. By applying our solution on one use-case, we got temporal thresholds 20–40 % less than the one usually used to alarm the system about security violations. Using our boundaries ensures the early detection of off-nominal temporal behavior and provides the system with a sufficient amount of time to initiate recovery actions.

Published: December 2020

Artificial Intelligence (AI) and Internet of Things (IoT) applications are rapidly growing in today’s world where they are continuously connected to the internet and process, store and exchange information among the devices and the environment. The cloud and edge platform is very crucial to these applications due to their inherent compute-intensive and resource-constrained nature. One of the foremost challenges in cloud and edge resource allocation is the efficient management of computation and communication resources to meet the performance and latency guarantees of the applications. Numerous research studies have been carried out to address this intricate problem. In this paper, the current state-of-the-art resource allocation techniques for the cloud continuum, in particular those that consider time-sensitive applications, are reviewed. Furthermore, we present the key challenges in the resource allocation problem for the cloud continuum, a taxonomy to classify the existing literature and the potential research gaps.
Digital Objects in Rhombic Dodecahedron Grid
Authors: Biswas Ranita , Largeteau-Skapin Gaëlle , Zrour Rita , Andres Eric
Published: December 2020

Rhombic dodecahedron is a space filling polyhedron which represents the close packing of spheres in 3D space and the Voronoi structures of the face centered cubic (FCC) lattice. In this paper, we describe a new coordinate system where every 3-integer coordinates grid point corresponds to a rhombic dodecahedron centroid. In order to illustrate the interest of the new coordinate system, we propose the characterization of 3D digital plane with its topological features, such as the interrelation between the thickness of the digital plane and the separability constraint we aim to obtain. We also present the characterization of 3D digital lines and study it as the intersection of multiple digital planes. Characterization of 3D digital sphere with relevant topological features is proposed as well along with the 48-symmetry appearing in the new coordinate system.
SLC12A8 plays a key role in bladder cancer progression and EMT
Authors: Li Shun-Lai , Li Zheng-Feng , Cao Qing-Wei , Wang Wen-Zhen
Published: December 2020

Bladder cancer is the most common malignant tumor of the urinary system. The intention of the present research is to explore the prognostic value and biological function of solute carrier family 12 member 8 (SLC12A8) in bladder cancer. The analysis based on the TCGA and ONCOMINE database revealed that the expression of SLC12A8 in bladder cancer was notably increased compared with the normal group. SLC12A8 expression was notably correlated with the age, pathological stage, T-stage, and lymph node metastasis of bladder cancer patients. Moreover, the patients’ overall survival was notably shorter in the high SLC12A8 group. Compared with the control, SLC12A8 upregulation enhanced the proliferative, invasive, and migratory capacities of bladder cancer cells and promoted the expression of epithelial–mesenchymal transition (EMT) protein markers including β-catenin, vimentin, snail, and slug, while reduced the expression of E-cadherin. In the case of downregulated SLC12A8 expression, the proliferative, invasive, and migratory capacities of bladder cancer cells and the expression of EMT protein markers presented the opposite trend. This study demonstrated that SLC12A8 was highly correlated with oncogenesis and progression of bladder cancer, indicating that SLC12A8 may be a meaningful biomarker for initial diagnosis and early treatment of bladder cancer.
Significantly enhanced second-harmonic generations with all-dielectric antenna array working in the quasi-bound states in the continuum and excited by linearly polarized plane waves
Authors: Han Zhanghua , Ding Fei , Cai Yangjian , Levy Uriel
Published: December 2020

The recently emerging all-dielectric optical nanoantennas based on high-index semiconductors have proven to be an effective and low-loss alternative to metal-based plasmonic structures for light control and manipulations of light–matter interactions. Nonlinear optical effects have been widely investigated to employ the enhanced interactions between incident light and the dielectrics at the Mie-type resonances, and in particular magnetic dipole resonances, which are supported by the semiconductor. In this paper, we explore the novel phenomenon of bound states in the continuum supported by high-index semiconductor nanostructures. By carefully designing an array of nanodisk structures with an inner air slot as the defect, we show that a novel high quality-factor resonance achieved based on the concept of bound state in the continuum can be easily excited by the simplest linearly polarized plane wave at normal incidence. This resonance further enhances the interactions between light and semiconductors and boosts the nonlinear effects. Using AlGaAs as the nonlinear material, we demonstrate a significant increase in the second-harmonic generation efficiency, up to six orders of magnitude higher than that achieved by magnetic dipole resonances. In particular, a second-harmonic generation efficiency around 10% can be numerically achieved at a moderate incident pump intensity of 5 MW/cm2.

Art and Global South: “Playing Venice” at the Kochi-Muziris Biennale (KMB)
Authors: Ciotti Manuela
Published: December 2020

This article employs artifacts from the KMB’s “material culture” as a lens into this institution’s branding process and, within it, its interaction with the Venice Biennale. It analyzes larger questions about the career of the biennale cultural form as it re-territorializes in a new location that is added to the art world map “in progress.” Historically, geographical location has been crucial for many biennales in the Global South to articulate their origin, identity, and claims vis-à-vis the global art world. Moreover, biennale proliferation especially in the South has produced cartographic re-imaginings aiming to destabilize the “center-periphery” configuration of the art world map. The article shows that the KMB does not reiterate ideological standings put forward by Southern biennales but crafts its positionality on different grounds. These entail simultaneously anchoring the KMB to histories of circulation in and out of South India tracing back at least two millennia and strategically weaving a relation with the archetypical Venice Biennale in the present.
Gene action in low nitrogen tolerance and implication on maize grain yield and associated traits of some tropical maize populations
Authors: Sunday Ige , Babatunde Ajiboye , Stephen Abolusoro , Charity Aremu , Kayode Obaniyi
Published: December 2020

Understanding the mode of inheritance of traits is vital in the selection of breeding methods for the grain yield and improvement of associated traits in a target environment. Combining ability is one of the powerful indices for the selection of the best cross combinations, parental lines that combine with other lines and the best breeding method for high grain yield improvement programmes. A total of 45 crosses were generated from ten maize varieties developed in low nitrogen environment in a diallel mating fashion without reciprocal. The resultant progenies were investigated in low- and highnitrogen soil to identify the mode of grain yield inheritance and those of related traits in the tested environments. Mean square analysis revealed the preponderance of additive and non-additive gene actions in the expression of maize grain yield and related characters tested under stress and optimal conditions. In this study, it is proved that both standard selection and hybridization breeding strategies are effective for the improvement of most traits involved. This experiment also confirmed the adequacy of sufficient variation in the gene pool present in the maize population that could be exploited in maize grain yield improvement programmes in the tropics. The ratio of SCA to GCA however emphasized the superiority of additive gene effects in the expression of most traits in the tested environments. The results, therefore, suggest that additive gene actions primarily condition the expression of maize grain yield and associated characters in the tested environments. Therefore, suggesting that the standard selection method would be effective for the improvement of most traits tested under the two environments.
A Theodicy of Kenosis: Eleonore Stump and the Fall of Jericho
Authors: Culwick Arlyn
Published: December 2020

When Joshua came to Jericho and encountered the captain of the LORD’s host, his stance appears much like the theodicist, who, facing the awful prospects of suffering, evil, or death, seeks assurance from God, asking, “are you for us or our adversaries?” (Jos 5:13). Yet the angel’s reply is not “yes,” as typical theodicies seek to answer on God’s behalf, but “No; rather I indeed come now as captain of the host of the LORD.” (Jos 5:14) The implication is political: the angel seeks to alter Joshua’s stance from one ordered to his own purposes to one ordered to the LORD’s. Like traditional theodicies, Eleonore Stump’s Wandering in Darkness (2010) does not sufficiently establish why a theistic God must create a world where, to preserve our capacity to freely love God, suffering is caused or permitted. I avoid this problem by finding a “kenotic” aspect in the action of signs in which the perennial problems of suffering and evil do not arise, and which is available to direct experience, making it empirically falsifiable in principle. Like the angel’s reply to Joshua, this invites a change from a speculatively grounded stance representing the hopes of a theodicist, to one formed from real interactions that transcend discourse.

The incessant increase number of cancer cases, motivates scientists to constantly develop and search for new therapies. Along with the dynamic development of anti-cancer drugs and therapies, we are witnessing huge progress in the world of science - the development of personalized medicine. An inseparable element is also a very strong trend in the development of new in vitro animal models for chemotherapeutic research. Cell cultures are commonly undertaken by research models before animal testing. They are the basis for the development of new diagnostic and cancer treatments. It should be emphasized that basic research is a strong foundation for any therapy introduced. This chapter provides an overview of the modern cell culture techniques that are currently developing, which allow the introduction of modern models that reflect the organs and physiological system. Currently available cell culture methods are a key aspect of studying these interactions, however, a method that eliminates the limitations of standard methods is still being sought.
Tuning the properties of RF sputtered tin sulphide thin films and enhanced performance in RF sputtered SnS thin films hetero-junction solar cell devices
Authors: Nwofe Patrick Akata , Sugiyama Mutsumi
Published: December 2020

Tin sulphide (SnS) thin films were grown using the RF sputtering techniques. The working pressures (WP) were tuned between 0.70 and 4.00 Pa at fixed RF power of 100 W and deposition time of 2 min. X-ray diffractometry studies indicate that the films crystallized in the orthorhombic crystal structure and were single phase. The crystallite size increased up to a critical working pressure of 1.33 Pa and decreased thereafter with increased WP. Scanning electron microscopy (SEM) indicates that the films exhibit columnar grain structures. Energy dispersive spectroscopy indicates that the films are slightly Sn-rich. Transmittance and reflectance plots exhibits interference pattern, an indication that the films were of uniform thickness. Analysis from the optical data gives optical absorption coefficient (α) > 104 cm−1, and direct energy bandgap that exhibits relative decrease with the deposition conditions. Electrical studies from Hall effect measurements indicates that the films possess p-type electrical conductivity, and carrier concentration of 1016 cm−3 for films grown at WP of 1.33 Pa. The RF sputtered SnS thin films grown on Mo-substrates served as absorber layers to fabricate thin film hetero-junction solar cell devices in the substrate configuration with a cadmium sulphide (CdS) window partner. The best device yielded a short circuit current density of 25.94 mA/cm2, open circuit voltage of 0.087 V and an enhanced solar conversion efficiency of 0.60%. A world record value for RF-sputtered SnS/CdS based hetero-junction thin film solar cell devices.

Authors: Zoller Michael , Huppertz Hubert
Published: December 2020

The rare earth oxoborates REB5O8(OH)2 (RE = Ho, Er, Tm) were synthesized in a Walker-type multianvil apparatus at a pressure of 2.5 GPa and a temperature of 673 K. Single-crystal X-ray diffraction data provided the basis for the structure solution and refinement. The compounds crystallize in the monoclinic space group C2 (no. 5) and are composed of a layer-like structure containing dreier and sechser rings of corner sharing [BO4]5− tetrahedra. The rare earth metal cations are coordinated between two adjacent sechser rings. Further characterization was performed utilizing IR spectroscopy.

Human hair is a biological sample that is, unlike blood, noninvasively collected and can be used in the assessment of element intake. Before analysis, hair samples need to be washed to eliminate external contamination, for which no standard procedure exists. The present study evaluated the efficiency of different processes for washing hair samples (by non-ionic detergent, acids, solvents, and their mixtures), including ultrasonication before ICP-MS element (As, Ca, Cd, Cu, Fe, Hg, Mg, Mn, Mo, Pb, Se, and Zn) analysis. All tested washing procedures using detergent or solvents were satisfactory, while nitric and hydrochloric acid solutions yielded to “released” and lost elements due to damaged hair (visible discolouration and hair impairment). The application of ultrasonication improved washing efficiency up to 10 %, depending on the tested element and washing procedure.

Obtención de energía eléctrica por celdas de combustión microbiana con plantas, en un sistema de una sola cámara sin el uso de membranas
Authors: Danna Melissa Gámez Hernández , Maria Camila Romero Mejía
Published: December 2020

Las celdas de combustión microbiana son dispositivos que aprovechan la biodegradación de la materia orgánica para transformarla en electricidad. Las plantas sintetizan materia orgánica a través de la fotosíntesis, y la degradan con ayuda de los microorganismos que se encuentran en la rizosfera (raíces de las plantas). La estructura básica del mecanismo consiste en dos cámaras que difieren en las condiciones de oxigenación, separadas por una membrana. Sin embargo, estas membranas son de alto valor, que al usarlas incrementan el costo principal de esta tecnología. Se evaluó la producción de energía eléctrica midiendo la diferencia de potencial generada en un sistema de una sola cámara sin membrana, que emplea 4 individuos del género Brachiaria como fuente de micorrizas, minas de grafito como electrodos y enriquecimiento microbiano del ánodo con bacterias provenientes aguas estancadas para la optimización del dispositivo. El voltaje varió a lo largo del experimento y se obtuvo 160,4 mV como valor máximo.

Authors: Jeimy Lorena Muñoz Díaz , Erika Katerine Rodríguez Alvarado
Published: December 2020

La calidad del aire garantiza un ambiente sano para la comunidad, sin embargo, dados los procesos industriales se ha deteriorado dicha calidad a causa de la emisión de contaminantes como NOx, CO y COV, los cuales, junto con la radiación solar, reaccionan de forma fotoquímica produciendo un contaminante secundario, altamente oxidativo, el ozono (O3). Este documento busca proponer una herramienta clara, que permita reconocer cuáles son los lineamientos necesarios en el momento de articular un programa de seguimiento y monitoreo del contaminante atmosférico mencionado anteriormente. A través del estudio que se lleva a cabo se relaciona información respecto a : ¿cómo es la formación del O3?, ¿qué efectos produce?, ¿cómo es el estado actual de los Sistemas de Vigilancia de Calidad del Aire en el país?, respecto al O3, ¿cuál es el método de referencia para realizar el seguimiento?, y ¿cuál es la normativa que controla dichos límites máximos permisibles?, entre otros aspectos. Por lo tanto, como resultado, se obtendrá una ficha técnica que propone los lineamientos de la medición de la calidad del aire en cuanto a ozono (O3) y su desarrollo a tarves de un caso estudio que ejemplifica al lector como debe ser su implementacion en programas de seguimiento y monitoreo. Se concluye que esta herramienta propuesta permitirá tener de forma clara, las medidas que se deben adoptar para realizar un seguimiento y monitoreo que cumpla con los criterios exigidos por las normas, a fin de obtener información confiable y verídica, que permita fortalecer e implementar programas de prevención, control, seguimiento y monitoreo de O3, con el fin de garantizar una calidad de aire a la población.
