The Basic Theorem of Temperature-Dependent Processes
Authors: Sapunov Valentin N. , Saveljev Eugene A. , Voronov Mikhail S. , Valtiner Markus , Linert Wolfgang
Published: March 2021

The basic theorem of isokinetic relationships is formulated as “if there exists a linear correlation “structure∼properties” at two temperatures, the point of their intersection will be a common point for the same correlation at other temperatures, until the Arrhenius law is violated”. The theorem is valid in various regions of thermally activated processes, in which only one parameter changes. A detailed examination of the consequences of this theorem showed that it is easy to formulate a number of empirical regularities known as the “kinetic compensation effect”, the well-known formula of the Meyer–Neldel rule, or the so-called concept of “multi-excitation entropy”. In a series of similar processes, we examined the effect of different variable parameters of the process on the free energy of activation, and we discuss possible applications.
The Use of the Contamination Index and the LWPI Index to Assess the Quality of Groundwater in the Area of a Municipal Waste Landfill
Authors: Knopek Tomasz , Dabrowska Dominika
Published: March 2021

Environmental degradation caused by the migration of pollutants from landfills is one of the biggest problems for urban areas. Systematic monitoring of groundwater in the vicinity of waste dumps allows for an assessment of the degree of risk to the soil and water environment. In this paper, spatiotemporal variation of groundwater pollution near a municipal landfill in Sosnowiec (southern Poland) was investigated. For this purpose, the monitoring results of five physicochemical indicators from 2014–2019 were used. This study presents an example of the application of the Landfill Water Pollution Index (LWPI) and the Cd Contamination Index. The obtained results indicated that the tested waters were negatively influenced by municipal landfills, especially in the southern part (piezometers P8 and P10). The values of the Contamination Index even reached a value equal of about 1400, while the values of the LWPI index reached 305. Significantly lower values of both indicators were obtained using the results of monitoring studies for other piezometers located upstream from the landfill but belonging to the observation network of a neighboring facility. The indices used permit a determination of the level of groundwater contamination from the described landfill and can be used in similar research areas.

The COVID-19 global pandemic is entering its second year. In this short report we present additional results as a supplement to our previous paper on COVID-19 and common respiratory virus screening for healthcare workers (HCWs) in a tertiary infectious disease referral hospital in Manila, Philippines. We sought to understand what etiologic agents could explain the upper/lower respiratory tract infection-like (URTI/LRTI-like) symptoms exhibited by 88% of the 324 HCWs tested. Among the patients who had URTI/LRTI-like symptoms, only seven (2%) were positive for COVID-19, while 38 (13%) of the symptomatic participants were identified positive for another viral etiologic agent. Rhinovirus was the most common infection, with 21 (9%) of the symptomatic participants positive for rhinovirus. Based on these results, testing symptomatic HCWs for common respiratory illnesses in addition to COVID-19 should be considered during this time of global pandemic.

A Commentary on Realities of Developing COVID-19 Vaccines Discussed through the Global Health Safety Perspective
Authors: Al-Qahtani Wedad , Safhi Fatmah
Published: March 2021

SARS-CoV-2 (or simply COVID-19) remains to be a global pandemic issue affecting millions, thus urging the world’s scientific community to develop efficient vaccine and design adequate measures of disease control. Currently, the most economically viable solution to infections and viruses is vaccination, despite the possible concerns about side effects from implementing quickly developed vaccine. The current commentary intends to explain the health and safety related to COVID-19 vaccines via a prism of global health safety. Scientists across the globe, along with companies from both public and private sectors, have predictably arranged cooperative programs to learn about COVID-19, along with taking simultaneous steps on devising vaccine and preparing effective treatments plans. Presently, several clinical trials to approve the efficiency of proposed vaccine solutions have been made successfully. Global health safety concerns on vaccine’s efficiency such as high costs of production, provision of vaccine to developing countries, and its influence on the global economy are addressed. This commentary reflects on current efforts related to the development of vaccine against COVID-19, which currently affects the global health status and economy. In addition, the commentary aims at addressing potential risks related to the development of COVID-19 vaccine from the global health safety perspective.

Published: March 2021

Acute pancreatitis is an acute inflammatory process in the pancreas that is common in dogs. This study was designed to compare cytokines between healthy dogs and dogs with suspected acute pancreatitis. For the canine cytokine antibody array, three healthy dogs and three dogs with suspected acute pancreatitis were included. Interleukin (IL)-2, IL-6, IL-10, GM-CSF, and TNF-α were not detected in either group based on the results. Conversely, IL-8 (p = 0.035), Monocyte Chemoattractant Protein-1 (MCP)-1 (p = 0.0138), Receptor for Advanced Glycation Endproducts (RAGE) (p = 0.0079), and stem cell factor (SCF) (p = 0.034) were significantly increased in dogs with suspected acute pancreatitis. However, vascular endothelial growth factor (VEGF) (p = 0.6971) did not differ significantly between groups. For the canine serum Enzyme-Linked Immunosorbent Assay (ELISA), eight healthy dogs and eight dogs with suspected acute pancreatitis were included. ELISA revealed that IL-8 (p < 0.0001), MCP-1 (p < 0.0001), RAGE (p = 0.006), and SCF (p = 0.0002) were all significantly upregulated in the experimental group. We confirmed multiple patterns of cytokines in suspected acute pancreatitis of dogs via canine cytokine antibody array using a small quantity of serum. After this procedure, we reevaluated the cytokines, which were significantly increased in dogs with suspected acute pancreatitis, by ELISA, with more samples. Through this study, we confirmed that MCP-1, RAGE, and SCF were newly suggested factors in dogs with suspected acute pancreatitis.
Investigating the Result of Current Density, Temperature, and Electrolyte Concentration on COD: Subtraction of Petroleum Refinery Wastewater Using Response Surface Methodology
Authors: Chakawa Sharon , Aziz Mujahid
Published: March 2021

Electrochemical oxidation (EO) investigated chemical oxygen demand (COD) subtraction from petroleum refinery wastewater (PRW) as a capable remediation process. Titanium substrates coated with iridium–tantalum oxide mixtures (Ti/IrO2–Ta2O5) were used as the dimensional stable anode (DSA). The Box-Behnken Design (BBD), a statistical experimental design and response surface methodology (RSM), was used to matrix the current density, temperature, and electrolyte (NaCl) concentration variables, with COD removal efficiency as the response factor. A second-order verifiable relationship between the response and independent variables was derived where the analysis of variance displayed a high coefficient of determination value (R2 = 0.9799). The predicted values calculated with the model equations were very close to the experimental values where the model was highly significant. Based on the BBD for current density, the optimum process conditions, temperature and electrolyte (NaCl) concentration were 7.5 mA/cm2, 42 °C and 4.5 g/L, respectively. They were resulting in a COD removal efficiency of 99.83% after a 12-hour EO period.
Optimal Design of District Metered Areas in a Water Distribution Network Using Coupled Self-Organizing Map and Community Structure Algorithm
Authors: Bui Xuan Khoa , Marlim Malvin S. , Kang Doosun
Published: March 2021

Operation and management of a water distribution network (WDN) by district metered areas (DMAs) bring many benefits for water utilities, particularly regarding water loss control and pressure management. However, the optimal design of DMAs in a WDN is a challenging task. This paper proposes an approach for the optimal design of DMAs in the multiple-criteria decision analysis (MCDA) framework based on the outcome of a coupled model comprising a self-organizing map (SOM) and a community structure algorithm (CSA). First, the clustering principle of the SOM algorithm is applied to construct initial homologous clusters in terms of pressure and elevation. CSA is then coupled to refine the SOM-based initial clusters for the automated creation of multiscale and dynamic DMA layouts. Finally, the criteria for quantifying the performance of each DMA layout solution are assessed in the MCDA framework. Verifying the model on a hypothetical network and an actual WDN proved that it could efficiently create homologous and dynamic DMA layouts capable of adapting to water demand variability.

Published: March 2021

The aim of community service is that high school youth after attending counseling can increase knowledge about balanced menus and the benefits of iron tablets in an effort to prevent anemia. Increasing the value of pre-test-post-test the level of knowledge about the balanced menu and the benefits of target iron tablets (blood-added tablets) at SMKN 1 Sukawati ranged from 0.0-50.0 with an average of 16.5 (SD = 11.39), whereas in SMAN 1 Sukawati ranged from 0.0-58.3 with an average of 32.1 (SD = 16.51). Based on a paired test statistical analysis it turns out that the pre-test value of the level of knowledge is significantly different compared to the value of the post-test (p = 0,000), which means the counseling method provided is effective for increasing target knowledge about balanced menus and the benefits of iron tablets. In practice the balanced menu is generally good because it meets the principle of a balanced menu. The menu type is good, namely consumption for lunch consisting of staple foods, animal and vegetable side dishes, vegetables and fruit. The number of menus selected still needs attention, especially the amount of vegetables and rice.

It dates from Hadrian’s time and was issued for a soldier from cohors II Augusta Nerviana Pacensis milliaria Brittonum garrisoned in the fort at Buciumi (Sălaj County) on the frontier of Dacia Porolissensis. The document is a more complete copy of a fragmentary one already known. The diploma mentions one cavalry unit and eight infantry troops from the province’s army. The authors discuss the strange order of troops in the new diploma and highlight the accurate mention of the complete titles of the units.
Brooches of type Almgren Group VII, Series I, Variation with Headknob and Vertical Catchplate, from East and South-East Romania (the Barbarian World)
Authors: Cociș Sorin , Bârcă Vitalie
Published: March 2021

We attempt herein, based on archaeological finds, to analyse brooches of type Almgren VII, Series I, the headknob and external chord variation from territories east and south-east of Romania. The authors discuss a number of 46 such brooches. The typological analysis of the finds as well as the approach of the other issues these raise, also considered similar specimens diffused on a vast geographical area and a chronological time span comprised between the last decades of the 2nd century – early 4th century AD. Out of the total analysed exemplars, 35 were discovered in settlements and 11 in cemeteries, of which four were identified in inhumations. Out of the total brooches, only three are in silver, while with respect to the spring making type, 24 are single springed, five are provided with a double spring while in the case of 17 exemplars, it was impossible to say with certainty whether they had a single spring and chord inserted through the second hole of the support or were double-springed. Subsequent to the analysis of these type brooches and the contexts and features where they were discovered, the authors concluded that chronologically, the specimens date in the area under discussion mainly to stage C1b – early stage C3 (AD 230-320/330), though emerging in the late period of stage C1a. The authors noted, based on finds yielded by certain graves, that these were often worn in pairs, a custom specific mainly to the Germanic world, ascribing their wear to women. Based on the examination of the finds, the authors further noted that in the area discussed here it may be currently assumed that brooches of the sort were manufactured only at Bucharest-Străulești, reminding though both their making in several other sites within territories located outside the Roman empire and by possible travelling artisans. Also, it is mentioned again that these brooches of type Almgren, group VII, series I, emerged in the Przeworsk and Wielbark culture environments, where many such brooch finds are found, together with most numerous subvariants. The authors also conclude that the presence of these brooches may be related to the territories north and north-east of the Upper Dniester and that they are indicative, beside other artefacts, of the arrival and settlement in the discussed area, starting with the end phase of stage C1a – early stage C1b, of certain groups of Germanic populaces from the region of the Upper Dniester and territories north of it. Last but not least, the authors construe that in the current state of research, it is impossible to reach more definite conclusions on who were the bearers of these brooches, mentioning though that it is not excluded that their emergence is connected to the arrival of the bearers of the early stage (beginning) of the Sântana de Mureș-Chernyakhov culture on the territory east and south of the Carpathians.

Authors: Cosma Călin
Published: March 2021

On the territory of Transylvania I have recorded 15settlements where stirrups have been discovered (Tab. 1-2). I have recorded 13 settlements where bits were discovered. In four of them the bits were found in Gepidic-Avar cemeteries (Tab. 3-4). A series of items used for the distribution of harness straps and buckles for the harness leathers were discovered in horse graves or in graves with horses from 7th–8th century Transylvania that belonged to the Avars (Pl. 25). Fragments of iron sets and plates of various sizesfrom the metal structure of horse saddles had been deposited in the grave from Unirea 2/Veresmort (catalogue III. 5) and in the graves with horses from Șpălnaca(catalogue III.4.1). Horse saddles certainly existed in many more inhumation graves from Transylvania but have not been preserved. It should be noted that bothstirrups and bits were found in most graves that contained different types of weapons or other military equipment accessories.
The Coţofeni Discoveries on the Jidovu Mountain (Zlatna): Domestic or Ritual Context?
Authors: Popa Cristian Ioan
Published: March 2021

On the Jidovu mountain in Zlatna, the exploitation of an andesite extraction quarry recently destroyed a Coţofeni site. In 2014, from the area of the peak (952 m altitude), fragments of four ceramic vessels (a pitcher, an amphora, a mug and a cup) were recovered. Afterwards, in 2015, other fragments dispersed by the quarry explosions were also discovered. The presence of these materials is very important in the context of mountain archaeology. Two possible hypotheses were discussed, regarding the presence of certain large-capacity vessels (the 30 l pitcher, the 60 l amphora) on the mountaintop: the possible exploitation of andesite and a ritualistic deposit. The first hypothesis cannot be supported, since in the Coţofeni area, there are very few artefacts made of andesite. However, the much more plausible hypothesis is that of the existence of a ritualistic deposit, since similar associations of vessels also occurred in other places of worship, especially in the caves of the Apuseni Mountains. The possibility of the existence of a seasonal inhabitation is much smaller, given the conformation of the mountain. The Coţofeni site from Jidovu is part of a region in which many Coţofeni discoveries were made, in Zlatna and in the neighbouring areas, concentrated on the upper course of the Ampoi Valley. Unfortunately, the site was destroyed, in the absence of an archaeological survey, and no other data can be recovered.
Social Identities in Roman Children’s Burials. Roman Cemetery at Apulum-Dealul Furcilor
Authors: Mustață Mariana
Published: March 2021

The children’s graves from the cemetery at Apulum-Dealul Furcilor are a category of archaeological contexts that is worth studying because too little is known about the funerary treatments of the children from Roman Dacia. These graves contain the material remains of a number of practices that could indicate the perceived social identities of the child and the mourners. These coded identities can be deciphered by using statistical analyses, the process of understanding the archaeological assemblages being eased in this way. However, a proper interpretation of these contexts requires the incorporation of existing knowledge about the status of the Roman children, their activities, their surrounding material culture and the way in which it was handled, their obligations and rights, the relations with the parents and different relatives, etc. Therefore, the study of this theme could open many doors towards other related subjects.

The asymmetric impact of economic policy uncertainty on firm-level investment in South Africa: Firm-level evidence from administrative tax data
Authors: Lesame Keagile
Published: March 2021

This paper uses firm-level data and a news-based measure of economic policy uncertainty to provide empirical evidence that economic policy uncertainty has a negative impact on firm-level investment in South Africa. Firms’ investment decisions in response to uncertainty reflect firms’ heterogeneity. Medium-sized firms and, to a different extent, small firms reduce their investment by much more than large firms in response to increased policy uncertainty. The relationship between firms categorized by size and the degree of financial constraints they face implies that financially constrained firms are more sensitive to uncertainty than large, unconstrained firms.

Published: March 2021

Fixed oral prosthesis as of late has been a very viable option for oral rehabilitation, since these differ from removable prostheses in aesthetic, functional and biological parameters. As a result, they are always preferred by patients. Oral prosthesis´ have certain parameters to be fulfilled for its prosthetic indications, such as the number of teeth present in the mouth, the type of occlusion, the level of bone insertion in dental organs that will be used as pillars or stumps, the proportion of root to crown , the absence of periradicular lesions that put us in reserved forecasts for the rehabilitation of dental organs. Under the ideal parameters we will base the final diagnosis for the placement of the correct restoration either in the same prosthetic design, manufactured with an ideal material. The preservation of the residual edge in the edentula area will be respected so that the prosthesis does not play an irritating role within the oral cavity, a relevant factor when placing this type of restorations. A bad adjustment either in individual crowns, fixed bridges can chronically irritate the residual flange resulting in ulcerative, fungal or bacterial lesions. Biological thicknesses, residual flanges must always be respected when designing this type of definitive restorations.

Authors: Ahumada-Medina A , Chio-Austria R. M. , Ahumada-Gómez J.
Published: March 2021

The prevailing weather conditions in the Valles Altos of the Mexican state of Hidalgo enhance high frequency of frosts that usually last from September to April, causing serious damage and constraints on agricultural cycles, both open sky and protected agriculture. In this paper, the results of observations of the behavior of temperatures during night and early morning hours of an underground greenhouse built on the campus of the Polytechnic University of Pachuca are reported. These data allow for an innovative approach to the production of horticultural, ornamental and medicinal plants during the period of frost. After four years of continuous experimentation, there have been cultivated horticultural, ornamental and medicinal plants, during all months of the year, even when they came to present -10 degrees Celsius or lower coolings. As observed, one can conclude that the results have been satisfactory to the experimental design and, therefore, may try to build greenhouses of 2000 square meters with trade capacity throughout the year with some adaptations derived from a larger area.

Authors: Rodríguez-García Nabile Edith , Vázquez-Gálvez Felipe Adrián , Estrada-Saldaña Fernando , Hernández-Hernández Israel
Published: March 2021

There is a global concern for the increase in health costs in a poor air quality relationship especially in urban environments. In Ciudad Juárez, Chihuahua, although it has a discontinuous monitoring of air quality, there is no air quality program that includes thresholds and contingencies for poor quality. This article proposes an environmental quality index based on the algorithms of other entities and climatic variables typical of the characteristics of the city of Ciudad Juárez and El Paso. The system is in the way of integrating the measurements of gases such as Ozone, CO and PM2.5 as well as the meteorological variables of humidity, wind speed and temperature. To obtain the above, it is necessary to strategically install sensors in different areas of the city, extract their information, store them in databases, analyze the data and create a citizen warning mechanism when the value of the index can harm the health of people. Citizen participation is a fundamental element in the development of the project. This article shows the development of the environmental quality index for Ciudad Juárez and the results of the project.

Published: March 2021

Capsaicin and dihydrocapsaicin are responsible for 90% of the pungency of the fruit; the rest of the capsaicinoids participate to a lesser extent in the itching, but contribute strongly to the diversity of spicy flavors in the different species of Capsicum. In the present project the application of 7 treatment T1 = Chemical, T2 = Chemical + Bioferment, T3 = Chemical + Leached, T4 = Bioferment, T5 = Leached, T6 = Bioferment + Leached, T7 = Chemical + Leached + Bioferment, in greenhouse was evaluated and in open sky, a randomized block design with three repetitions was established. The variables evaluated were plant height, temperature, relative humidity, production weight, fresh weight, root depth, dry weight and pH. The data generated in this research indicate that the treatment that generated the most amount of capsaicinoids was the chemical treatment in the greenhouse with 37.7 ml of capsaicinoids and in the open sky with 36.96 ml.
Characterization of uses of trigonometric notions in Mechatronics Engineering from Mathematics Education
Authors: Torres-Corrales Diana del Carmen , Montiel-Espinosa Gisela
Published: March 2021

From the Socioepistemological Theory we propose that even with the curricular articulation presented in school programs of Engineering it exists a disarticulation of uses of mathematical knowledge, this is displayed more emphatically when a student takes professionalizing courses. We proposed the research question of: what uses of trigonometric notions are given in Mechatronics Engineering when students solve problems in Robotics? we use the Socioepistemological Theory in tandem with the ethnographic method to identify and characterize them in their cultural framework. By the delimitation of the study to a community of Mechatronics Engineering in a Mexican university and the direct kinematics problem in the subject of Industrial Robotics, we characterize that trigonometric notions are given an arithmetic, metric, quantitative and algebraic usage, and by them, the Trigonometry acquires more significates aided by the construction of visual references that allow the mathematical modelling that was done, and from which we recognize in the pseudo-concrete models (drawing and kinematic schemes) the reason to be for Trigonometry as a tool for Robotics: the determination of the position in a circle or circular sector.
Simulation framework for practical cyber security training in the public service
Authors: Deák Veronika
Published: March 2021

The public service sector is a key target of cyberattacks. In order to prevent and effectively tackle such attacks, organisations should
continuously develop their defence capabilities. As part of developing such capabilities, public service cybersecurity training is required
to teach students about cyberattacks. The present study uses quantitative research techniques including (i) how to identify key requirements for the practical aspects of public service cybersecurity training and (ii) sampling to utilise international best practices from
cybersecurity education and conceptual architectures from existing public service organisations. A schematic structure with a two-level
practical training course is proposed. On the first level, the students learn about the defence mechanisms of their own info-communication devices and try to prevent attacks in a simulated environment. On the second level, the students apply protection strategies against
cyberattacks in organisational infrastructure. Finally, a technical framework is defined to simulate cyberattacks against (a) personal
devices and (b) a fictional organisational infrastructure. The specification of a public service cybersecurity training programme should
not only focus on theoretical education but also provide practical knowledge to students. By simulating specific attacks, theoretical
and practical knowledge can be combined. As a result, students will be able to recognise threats and potential risks from cyberspace.

Nicolaus Copernicus University. The one-day conversation had three parts and each part consisted of two speeches. After each speech there was a short but very active discussion on the respective topics.
Limits of Life Shaped by Ethics: A Short Introduction to Tadeusz Ślipko's Bioethics
Authors: Aszyk Piotr
Published: March 2021

Bioethics is a fairly new, but very popular, discipline broadly present in the public debate of the Western Societies. It deals with difficult tasks and challenges faced by scientists to find ethical, social or political solutions to various problems created by modern science and technological growth. An impressive exploration of several bioethical issues can be found in the works of the Polish Jesuit, philosopher and, now a retired professor, Tadeusz Ślipko (born 1918). For decades, his scientific attention, apart from theoretical topics, was focused on the issues important to everyday human life. He placed a lot of emphasis on finding ethical solutions to the difficult issues discussed in the postwar Poland. He authored the first Polish ethical monograph devoted exclusively to modern problems of medical and technological development and titled Limits of Life. Dilemmas of the Modern Bioethics, first published in 1988 and reprinted in 1994.

A construção de Usinas Hidrelétricas (UHE) tem sido constante e em grande escala para atender a demanda por energia elétrica no Brasil. Mas, após a implementação desses empreendimentos, as características ambientais são alteradas, o que interfere negativamente na biodiversidade local. O meio ambiente é agredido bruscamente, causando inúmeros transtornos. Além disso, as comunidades ribeirinhas são impactadas diretamente pela construção de uma UHE. Nesse contexto, o presente trabalho visa investigar os impactos ambientais e sociais causados pela construção da UHE Estreito na cidade de Carolina, Maranhão. Para isto, em novembro de 2018, foram aplicados questionários junto a 20 famílias residentes neste município. O resultado desta pesquisa revelou que houve uma considerável elevação do lençol freático ali existente, causando transtornos à população, tais como: i) a saturação das fossas sépticas; ii) inundações, principalmente em áreas próximas ao lago ou a córregos e iii) rios que também tiveram seus cursos bloqueados pela formação do lago do rio Tocantins, causando rachaduras e/ou desmoronamentos nas edificações residenciais. Além disso, a pesquisa realizada apontou bastante insatisfação dos ribeirinhos atingidos pela construção da UHE.

Published: March 2021

O livro didático atinge seu propósito quando estabelece uma forte parceria com o professor, de maneira que possa converter em realidade os objetivos propostos para a educação. O presente estudo analisou cinco livros didáticos de biologia do 3º ano do ensino médio a fim de verificar como o ensino de biotecnologia tem sido contemplado e estruturado nesses materiais. A metodologia constou de análise bibliográfica investigativa e descritiva dos vários aspectos referentes aos temas de biotecnologia (precisão conceitual, atualização dos temas, imagens, concordância com o(s) capítulo(s) no(s) qual(is) estão inseridos nos livros de biologia. Os resultados indicam que existe uma disparidade entre os livros analisados demonstrando que os livros devem melhorar alguns aspectos observados, como quase a inexistência de sugestão de pesquisa com conteúdo da internet, raríssimos exercícios de fixação dos conteúdos e pouquíssimos textos sobre ética na Biotecnologia, embora essas obras podem auxiliar no processo de ensino-aprendizagem dos conceitos relacionados ao tópico investigado. Sobressaiu a linguagem aplicada na apresentação dos conteúdos, apesar de cientifica e formal, a conotação da linguagem utilizada é acessível de fácil compreensão sem expressões que dificultam o entendimento dos leitores. É impossível pensar em Ciências na atualidade sem associa-la aos assuntos discutidos na Biotecnologia seu estudo promove impactos em diversos setores da sociedade

Selective electrodes were modified by using the magnetic molecularly imprinted polymer (MMIP) technique on a screen-printed electrode (SPE) to detect bisphenol A (BPA). Superparamagnetic iron oxide nanoparticles (SPIONs) greatly enhance electrochemical signals due to their superparamagnetic properties. The SPIONs are non-toxic, biocompatible and highly stable. The SPIONs, especially magnetite (Fe3O4), were synthesized from ferrous chloride and ferric chloride using a chemical co-precipitation method. The crystalline structure of the synthesized SPIONs was obtained by X-ray diffractometer, representing cubic inverse spinel structure like magnetite. The synthesized SPIONs had particle sizes of 9.87 ± 2.67 nm, which was confirmed by transmission electron microscope. The magnetic property was measured by a vibrating sample magnetometer, which presented the saturated magnetization, magnetic remanence value and coercivity as 48.76 emu g−1, 0.497 emu g−1 and 6.265 Oe, respectively. The surfaces of modified electrodes were characterized by a scanning electron microscope, which revealed BPA template cavities on the electrode surface. The electrochemical properties were studied by cyclic voltammetry and amperometry. The bisphenol A-magnetic molecularly imprinted polymer electrode (BPA-MMIP/SPE) has a sensitivity of 2.909 with a limit of detection of 2.053 × 10−8 M. The concentration range for BPA detection is 2.5 × 10−8 to 1.00 × 10−4 M, which can be applied to detection in a real sample.

Introduction to rheometry for researchers of ultrasonics
Authors: Sakai Keiji
Published: March 2021

In this paper, some recent topics on the methodology of viscoelasticity are introduced for researching ultrasonics. First, the role of viscoelasticity in ultrasonic relaxation phenomena is briefly summarized from the viewpoint of rheology. Then, the relaxation of two-dimensional viscoelasticity studied by surface light scattering experiments, which is analogous to the Brillouin scattering to detect thermal phonons, is discussed. Progress in the general method of rheometry using a rotational viscometer is also shown, in which the remote sensing of the viscosity by an electromagnetic spinning (EMS) method is described. Also examined is the possible accuracy of magneto levitated EMS, which can lead to the quantum standard of viscosity. Finally, ultrafast measurement of liquid properties, including surface tension and viscoelasticity, in which the technologies of micro liquid manipulation are employed, is introduced.

Wekî çalakîyeka takekesî, rewşenbîrî û pêkveyî komên xwendinê bandoreka girîng li ser edebîyatê dikin. Di çend salên dawî da di nav demeka kurt da gelek komên xwendinê yên Kurdî hatine damezirandin. Ji van koman çend nivîskar derketin, her wiha wan çend kovar jî derxistin. Lewma çalakîyên van koman rêyeka nû ya girîng li ber edebîyata Kurdî vekir. Ji ber ku komên xwendinê nivîskaran di şêwirên xwe da dikin mêvan, pirtûkan dikirin têkilîyên wan ligel nivîskar û weşanxaneyan jî hene. Lewma me jî di vê lêkolîna xwe da ligel 24 komên xwendinê, 7 nivîskar û helbestkar û 9 weşanxaneyan hevpeyvînên nivîskî kirin.

El psicólogo en el contexto hospitalario. Un profesional de la salud imprescindible.
Authors:   Universidad Santiago de Cali, Obando Cabezas Lucely
Published: March 2021

Considerándose como un hecho observable que los psicólogos todavía no tienen claramente reconocido un lugar indiscutible y vital en el sistema institucional sanitario del país, en el siguiente texto se realiza una reflexión sobre las posibles causas de esta situación. Se recogen en el texto variadas razones que intentan reafirmar la importancia de este profesional en el medio hospitalario, señalando al final que los psicólogos deben aprender a asumir como parte de su cotidianidad, un vínculo profesional irremediablemente conflictivo y expuesto a tensiones en las instituciones sanitarias al ser infranqueables toda la serie de divergencias que se dan entre los principios fisiológicos y materialistas que promueven en estos espacios la medicina tradicional y una psicología imbuida y formada a partir de otros principios, comúnmente nombrados como metafísicos.
