Sequential Activation of Spatially Localized Oligonucleotides
Authors: Rubanov Moshe , Dorsey Phillip , Scalise Dominic , Schulman Rebecca
Published: June 2022

The programmable spatiotemporal activation of molecules could be used to create stimuli-responsive biomaterials capable of executing multistage sensing and computational processes. Here we develop a method for the activation of different DNA molecules in precisely specified locations and times within hydrogels. The activation locations are determined by patterning molecules to be released in their inactive form within hydrogels at resolutions of tens of microns, whereas the time of activation is controlled by a DNA strand displacement reaction cascade that releases the target DNA oligonucleotides at precisely specified time intervals. This programmed activation of DNA from hydrogel substrates thus enables the scalable development of DNA-based reaction-diffusion systems that regulate DNA strand availability in space and time. This system could be used as a platform to autonomously activate predefined chemical signals embedded within a soft material.

Published: June 2022

The biological relevance of early lanthanides, such as neodymium, remained undiscovered until methylotrophic bacteria with lanthanide-dependent metabolism were identified. The respective strains incorporate these elements into the active site of their key metabolic enzyme methanol dehydrogenase (MDH). Growth studies with the strictly lanthanide-dependent thermoacidophile Methylacidiphilum fumariolicum SolV and the mesophilic Methylorubrum extorquens AM1 ΔmxaF mutant demonstrate that the trivalent actinides americium and curium support growth in the absence of the essential lanthanides. In fact, the bacteria make no distinction between lanthanide and actinide ions if they have the correct size and oxidation state. Time-resolved laser-induced fluorescence spectroscopy, liquid scintillation counting, and inductively coupled plasma mass spectrometry confirm the bacterial uptake. The interchangeability of f-block elements is supported by very similar enzymatic activities of recombinant methanol dehydrogenase reconstituted with different metal ions. Our combined in vivo and in vitro results firmly establish that actinides support growth of methylotrophic bacteria, suggesting a potential biological role for these radioactive elements. Importantly, bacteria capable of utilizing actinides will also be able to mobilize these elements in the environment. This may lead to applications for bioremediation and recycling/separation of lanthanides and actinides.

Authors: Kim Se-Hoon , Lee Chang-Jin , Kim Wan-Il , Ko Kwang-Cheol
Published: June 2022

A cathode with an open-ended coaxial structure is experimentally investigated using an axial virtual cathode oscillator (vircator). To enhance the microwave power output, an open-ended coaxial cathode is installed in the axial vircator. The proposed cathode is designed based on the reciprocating frequency of the vircator. The operation features of an axial vircator with a solid cathode, an annular cathode, and an open-ended coaxial cathode are comparatively analyzed through simulations and experiments. Three cathodes are machined using graphite. A stainless steel mesh with a transparency of 70% is used as an anode. The anode-to-cathode gap is fixed to 6 mm. The vircator is driven using a 10-stage PFN-Marx generator with a characteristic impedance of 31 Ω. The PFN-Marx generator applies -150 kV voltage pulses with a 170–200 ns pulse width into the vircator. The microwave power from the solid and annular cathodes is 11.22 MW and 11.27 MW, respectively. The proposed cathode generates a microwave with a power of 12.65 MW while enhancing the microwave power by 13% compared with the solid and annular cathodes. The proposed cathode shows a frequency shift to 3.4 GHz, which is a much lower frequency than that of the solid cathode at 6.34 GHz.
A Dual Orthogonal Fed Monopole Antenna for Circular Polarization Diversity
Authors: Sung Youngje
Published: June 2022

A monopole antenna with circular polarization diversity and high isolation is proposed in this paper. The proposed antenna consists of two bent monopole antennas and a partial ground plane. Two monopole antennas are implemented on opposite planes with respect to the ground plane. The ground plane is a right-angled isosceles triangle, and the antenna is located at one end of the ground plane. Circular polarization (CP) characteristics are obtained using this structural asymmetry. In the proposed structure, the resonant frequency at S11 is controlled by the antenna length, and the null frequency at S21 (isolation) is controlled using the bending angle of the monopole and the distance between the two antennas. From the measured results, the CP operating bandwidth of the proposed antenna is 13.8% (1.76–2.02 GHz). The measured isolation is –50 dB at the resonant frequency and –20 dB within the operating bandwidth.

Published: June 2022

When a pair of calculable dipole antennas (CalDAs) with a 3-dB hybrid balun is used for a validation test of a constructed open area test site (OATS), the theoretical normalized site attenuation (NSA) curves of an ideal OATS for the CalDAs are required. This paper presents a method to calculate this theoretical NSA in the frequency range of 30 MHz to 1 GHz. The theoretical NSA was directly derived using the power mismatch and dissipative loss concepts of an NSA measurement system. Accurate antenna factors (AFs) above the ground plane were also needed and calculated to obtain the theoretical NSA. When free-space AFs are used to determine the measured NSA, AF correction factors known as mutual impedance correction factors are needed. Both free-space AFs and AF correction factors were also considered.

examen de grado en las reformas al Reglamento General de la Ley Orgánica de Educación Intercultural de los años 2015, 2020 y 2021
Authors: Mantilla Luis
Published: June 2022

La obtención del título de bachiller y la evaluación de examen de grado son procesos de evaluación que se definen en el Reglamento General de la Ley Orgánica de Educación Intercultural (RLOEI). A partir de las reformas al RLOEI de los años 2015, 2020 y 2021, se han desarrollo algunos cambios en ambos procesos en general, y en el examen de grado en particular.  En este sentido, el trabajo analiza la oscilación entre lo sumativo (cuantitativo) y lo formativo (cualitativo) de la evaluación de examen de grado a partir de las reformas realizadas al marco regulatorio de la educación en Ecuador en los años mencionados. Por medio de la definición de un marco conceptual sobre la evaluación de los aprendizajes, y la selección de un corpus de documentos clave para el análisis, se estudian los cambios realizados tanto en el proceso de obtención del título de bachiller como en la evaluación de examen de grado plasmados en los contenidos de los artículos 198 y 199 del RLOEI en cada reforma. Finalmente, el análisis concluye que, si bien en la actualidad el proceso de obtención del título de bachiller es claro en cuanto a sus requisitos y/o componentes, que han variado a través de los años, existe un desafío para la consolidación del examen de grado en cuanto evaluación sumativa, sus métodos e instrumentos específicos ya que, en las reformas de los años 2015, 2020 y 2021, se ha producido una oscilación de su carácter evaluativo.

Published: June 2022

We have been observing various preventive measures implemented to contain the COVID19 pandemic in the world since the new Coronavirus outbreak. Self-isolation, staying at home and keeping away from social gatherings and mobilities are some examples. We argue how people perceive the virus and the preventive measures are important to understand their response to the pandemic. So, we studied the metaphoric perceptions of individuals regarding the Coronavirus itself and the preventive measures. The given data of a sample of 318 individuals was categorized regarding the concepts of "coronavirus" and "stay at home". Both concepts had one common category, namely "precautionary". One prominent result is that most of the participants think that the virus has some positive and "Instructive" aspects, a warning that one must pay attention. Another important result is that staying at home is perceived as "restricting the leisure time", causing a restriction in the physical activity.

Published: June 2022

By combining the method of replication of polyurethane foam matrices at 1200 °C and modification in model SBF (Simulated Body Fluid) solutions of various compositions, open-pore calcium phosphate foam ceramics with a porosity of 53-60 % was obtained. The architecture and morphology of the calcium phosphate foam ceramics surface was formed by using polyurethane foam matrices («Granufoam», «STR») with different porosity and quantity of open pores. Modification of the calcium phosphate foam ceramics in SBF solutions of various compositions leads to a slight decrease in porosity to 3 %, which indicates the formation of an ultrathin apatite layer. The calcium phosphate-modified foam ceramics consisted of β-tricalcium phosphate, β-calcium pyrophosphate, α-tricalcium phosphate, and biomimetic apatite. In the standard SBF solution, the formation of apatite on calcium phosphate foam ceramics occurs slowly (14-56 days) and the strength increases by a factor of 2 as compared to the initial one. Soaking of calcium phosphate foam ceramics in SBF without HCO3- leads to the formation of biomimetic apatite with inclusions of calcium chloride dihydrophosphate in spherulites. Modification in a 5-fold concentrated SBF solution for 3-5 days at 37 °C makes it possible to form 6-10 times more biomimetic apatite compared to standard SBF with a 2.5-fold increase in static strength to 0.05 MPa. It has been established that at 800 °C biomimetic apatite crystallizes into β- tricalcium phosphate.

Authors: Henarava T. M. , Leschev S. M. , Kartuzava A. A.
Published: June 2022

The problem of alternative sources of hydrocarbon fuels is currently of great importance. The constant growth of organopolymer waste, in particular, automobile tires, has stimulated the search for ways to recycle them. It was found that a promising method of their processing is pyrolysis in various modes [1]. A comprehensive study of the composition and properties of the resulting pyrolysis oils obtained from used tires will make it possible to find out the possibility of their use as a secondary raw material for the production of hydrocarbon fuels. In this work, the component composition of heavy paraffinic oil from the Rechitsa field and pyrolysis oil obtained during the thermal treatment of rubber products in a nitrogen atmosphere, by methods of IR spectroscopy, elemental and GC-MS analysis, has been investigated. In addition, their fractional composition, density of fractions, as well as iodine number have been determined. Based on the results obtained, conclusions were drawn about the similarities and differences between pyrolysis oil and petroleum. It has been suggested that liquid pyrolysis products, after appropriate treatment, can be used as additives to petroleum products, which contributes not only to solving the problems of both the disposal of used tires, but also the depletion of readily available oil reserves.

Published: June 2022

In order to process primary manganese-zinc chemical current sources, the technology for processing and separation of active mass components is optimized. The technology involves the extraction of zinc in the form of powder and in the form of coatings. Manganese compounds will be extracted in the form of manganese dioxide, while reducing the hazard class of waste to the fourth. The quantitative and qualitative composition of the electrolyte after leaching was determined by titrometric method. The highest concentration in the leaching electrolyte was observed for zinc Zn2+ and manganese Mn2+ ions, their concentrations were 34 and 41.36 g/dm3, respectively. Fe2+ iron ions were present in small amounts in the solutions. Using electrolytic processing of acid and alkaline solutions by leaching the active mass of spent manganese-zinc current sources, zinc in the form of coating was extracted.
Salt composition and physicochemical processes in the volume of fertilizer granules at the storage stage
Authors: Dormeshkin O. B. , Hauryliuk A. N.
Published: June 2022

The results of studies of the salt composition and physicochemical processes occurring in separate layers (volume) of granules of complex fertilizers based on ammonium phosphates at the stage of storage in the interval up to 180 days are given. The data of chemical and physicochemical studies, as well as the analysis of microphotographs and element-by-element composition of granules showed the absence of a significant gradient of concentrations of individual components in the volume of granules when they arrive from the technological process. The course of secondary conversion processes in the volume of granules during 3 and 6 months of storage was established, leading, in particular, to a significant decrease in the content of ammonium dihydrogen phosphate in the product from 25.41-27.91 to 1.23-3.25 % and urea, as well as the formation of newdouble salts and adducts: (Kχ,(NH4)1-χ)•H2PO4, CO(NH2)2•NH4Cl. The change in the phase composition of the product during long-term storage and the associated chemical interaction between the layers of individual granules is accompanied by an increase in caking. It is established that during 3 and 6 months of storage, the content of the liquid phase increases, which leads to a partial decrease in the content of individual components. The most active process of sorption of water vapor proceeds in the 1st (outer layer) of granules, while fluctuations in its content in deeper layers are within the margin of error. The dependence of the caking of the product on the type of injected nitrogen-containing component and the forms of nitrogen content in it has been established. The results of the study made it possible to recommend ways to reduce caking and improve the physical and mechanical properties of complex fertilizers during their storage and transportation: increasing the molar ratio at the ammoniation stage to values corresponding to the formation of diammonium phosphate; increasing the ratio of ammonium to the amide form of nitrogen; an increase in the proportion of granular urea in the composition of the fertilizer, followed by the complete exclusion of prilled urea.

It was established that the combined adding of amyl alcohol with alkylmorpholine and glycolic ether with alkylmorpholine in the process of sodium chloride flotation allows achieving high technological performance and reduces the consumption of expensive alkylmorpholine by 2 times. The use of pine oil as a foaming agent in a mixture with alkylmorpholine has been established to reduce the collector consumption by 2.2 times.
Comparative evaluation of infarct-limiting efficiency of postconditioning with lactate in ischemia-reperfusion of the myocardium in young and old rats and rats with transient hypercholesterolemia
Authors: Chepelev S. N. , Vismont F. I. , Goubkin S. V.
Published: June 2022

Taking into account the high medical and social significance of the problem of treating patients with coronary heart disease and acute myocardial infarction, the search for new effective methods of preventing or weakening ischemic and reperfusion myocardial damage and finding out the mechanisms of their implementation is an urgent task of modern experimental and clinical medicine. The aim of the study was to conduct a comparative analysis and clarification of features of the cardioprotective efficiency of postconditioning with lactate in ischemia-reperfusion of the myocardium in young and old rats and rats with transient hypercholesterolemia (HCE). It was found that remote ischemic postconditioning (RIPostC) in ischemia-reperfusion of the myocardium has an infarction-limiting effect and is accompanied by an increase in the level of lactate in the blood, and lactate after injection into the bloodstream of animals at a dose of 10 mg/kg 25 min after the start of reperfusion leads to a decrease in the size of the necrosis zone in the left ventricular myocardium in young and old rats. However, postconditioning with lactate is not effective in limiting the size of the zone of necrosis in the left ventricular of myocardium in young and old rats with transient HCE. There is reason to suppose that hyperlactatemia takes part in the realization of the cardioprotective effect of RIPostC. The presence of such a risk factor for cardiovascular diseases as HCE can serve as a criterion for excluding the use of postconditioning with lactate as a way to reduce ischemic and reperfusion damage to the myocardium in patients with acute myocardial infarction.
Antimicrobial Photodynamic Therapy of Human Skin
Authors: Mackay Alison M
Published: June 2022

Photodynamic therapy (aPDT) has become an important component in the treatment of human infection. This report highlights the scientific literature and clinical guidelines on aPDT in the context of dermatology and considers the treatment of skin infection in all settings now, and in the future. Antibiotic resistance, infection control strategies and technologies able to eradicate microbes without building up new resistance are considered, and their mechanisms of action are described. Published work and National Institute for Clinical Excellence (NICE) Technology appraisals (TA) and research recommendations within Clinical Guidelines were used to identify future applications for PDT. Nanotheranostics can include PDT and were found to be highly relevant, and so treatment combinations and their novel applications will be subject to TA and Randomised Clinical Trials (RCTs). The resistance of some microbes to antibiotics can be reversed through use of supplementary drugs, and so they are likely to remain a mainstay of treatment for skin infection.
The Effect of Sociodemographic and Environmental Factors on Food Consumption Expenditure of the Urban Poor in Indonesia
Authors: Kustanto Andi
Published: June 2022

This paper aims to assess sociodemographic and environmental factors on food consumption expenditure of urban poor households in 33 provinces in Indonesia from 2008-to 2019. The data used in this study were sourced from the Central Bureau of Statistics. The method used is panel data econometrics with a fixed-effect model. This study provides empirical evidence that income per capita, population, family planning acceptors, and single residents have a positive and significant effect on the food consumption expenditure of the urban poor. Meanwhile, access to drinking water and improved sanitation has a negative and significant effect on food consumption expenditures for the urban poor. The policy implication that can be prioritized is to increase human capital investment because it will increase competence and employment opportunities so that the income earned can increase consumption. Increasing family planning acceptors is also needed to suppress the population growth rate because if there are additional family members, it will increase the consumption burden. This will impact increasing poverty if a level of welfare does not accompany it. In addition, access to drinking water and improved sanitation needs to be improved because they impact the health of the population in the long term

The vertical garden is a garden that is designed using a separate structural system so that it can be erected or affixed to the wall. The principle of making a vertical garden must meet the requirements consisting of sunlight, types of plants, and water used. In addition, the manufacture of vertical gardens can use media such as bottles that are not used. The vertical garden is one way to improve land-use efficiency. Several types of plants can be grown using the vertical garden method, such as food crops, ornamental plants, and medicinal plants. Plants that have medicinal properties are now quite easy to find growing around the house. Medicinal plants are types of plants in which certain parts of the roots, stems, bark, leaves are believed to relieve or reduce pain. Therefore, this activity was carried out to introduce the technique of planting vertical gardens and several types of plants that can be planted with this technique, one of which is medicinal plants

Published: June 2022

This work was on non-activated and activated lateritic soil used in proportions of 0 % to 30 %, to replace fine sand by wt. %, in the production of lateritic concrete. A mix of 1: 2: 4 was used, and the cube samples were cured in four (4) curing media of water, sand, polythene, and sawdust. The aim was to evaluate the effects of these curing methods on the mechanical strengths, and other properties of lateritic concrete. The sensitivity of the generated data was characterized statistically and developing linear regression models for predictions. For the Non-Activated Laterite soil (NALS, control mix (0 %)), the design strength of 20 MPa was achieved by all the curing methods (standard and non-standard). However, for other replacement levels, water curing was adequate for 10 % and 30 %, sand at 10 %, and sawdust for 20 % and 30 %, respectively. On the other hand, for the Activated Laterite soil (ALS), the 20 MPa design strength was met only at 0 % replacement for all curing methods. Sawdust medium at 10 % also satisfied the 20 MPa strength.

During both hot and cold seasons, masonry walls play an important role in the thermal performance between the interior and the exterior of occupied spaces. It is thus essential to analyze the thermal behavior at the hollow block’s level in order to better understand the temperature and heat flux distribution in its structure and potentially limit as much as possible the heat transfer through the block. In this scope, this paper offers an experimental and numerical in-depth analysis of heat transfer phenomena inside a hollow block using a dedicated experimental setup including a well-insulated reference box and several thermocouples and fluxmeters distributed at the boundaries and inside the hollow block. The block was then numerically 3D modelled and simulated using COMSOL Multiphysics under the same conditions, properties, and dimensions as the experimentally tested block. The comparison between the numerical and experimental results provides very satisfactory results with relative difference of less than 4% for the computed thermal resistance.

Nigeria waters are rich with a variety of fish species but only very feware cultured and available for consumption. This study was conducted toknow the fillet quality, gut content and condition of Parachanna obscuraand Clarias agboyiensis in Nigeria using Igbokoda river as a referencebecause it is a the major fishing site in the nation. Studies were conductedon the viscera somatic index based on the organ weight and the bodyweight of the fish and the food item consumed by Parachanna obscura andClarias agboyiensis between May to October, 2019 to infer on the filletquality and gut content of P. obscura and C. agboyiensis in the water bodyrespectively. A summary of food items that constituted the diet of Clariasagboyiensis are Baccillariophyta, fish, fat droplets, dinoflagellate, insectand Chlorophyta which constituted the most important food items bothoccurring in all stomachs containing food. The fishes has more muscle thanthe viscera organs which indicate that the weight of the fish before dressingout is higher than the weight of the fish after dressing out. This is suggestiveof a good quality of food fish. There was a significant correlation betweenbody weight and total length of specimens found in this study. Increasesin total length resulted in corresponding increases in body weight. Theresult for the condition factor showed was below the expected or standardvalue (K = 1) which shows this species was not in favorable environmentalcondition. It is therefore necessary to allow phytoplanktons grow well inwater body to increase availability of food items to Parachanna obscuraand Clarias agboyiensis. P. obscura and C. agboyiensis are also good foodfishes of a high fillet quality. They are omnivorous feeders therefore havingpotentials for aquaculture.
