Published: March 2020

The diversity of race and culture makes Indonesia a country with abundance of culture. Traditional houses which have diverse form are symbol and reflection of culture in every tribe in Indonesia. The shape and architectural value of traditional Bugis houses in Sulawesi Selatan which still remains thanks to the efforts of Bugis tribe community is an example of house-building culture which still exists today.The involvement of cultural leader such as Sanro bola in tradition of Bugis’ house-building culture is essential, because they have knowledge and experiences passed on through generations. This study aims to reveal the role of Sanro bola in preserving the traditional values of building a Bugis Soppeng house. The method of this research is qualitative with explorative analysis. The result of the study revealed that the role of Sanro bola in the process of building a traditional Bugis Soppeng house divided into 6 aspects; as leader, material selection, considering about a good time and day, house orientation, constructing of traditional houses, and application of philosophy sulapa epapa'e. These six aspects are applied by Sanro bola in both physical and non-physical with the aim of providing direction and safety for the residents of the house.
IIRSA, subimperialismo brasileño y resistencias populares. Los conflictos en torno a la represa de Inbambari (Perú) y de la carretera sobre el TIPNIS (Bolivia)
Authors: Féliz Mariano , Melón Daiana Elisa
Published: March 2020

Este artículo aborda la forma en que el proyecto brasileño de desarrollo dependiente se desenvuelve en la constitución y consolidación de la Iniciativa para la Integración de la Infraestructura Regional Suramericana (IIRSA). Retomando los postulados de la teoría de la dependencia, específicamente los de Marini, se analizan las tendencias subimperialistas emanadas de Brasil, a partir de la promoción de un tipo de integración y una división regional del trabajo al servicio de los intereses de su burguesía. Así, se realiza un análisis de la IIRSA como etapa reciente de las estrategias de integración sudamericana. A su vez, se discute de qué forma la estrategia subimperialista brasileña y las resistencias populares se manifiestan en la Iniciativa a través de dos proyectos de inversión: la represa Inambari en Perú y la carretera sobre el Territorio Indígena y Parque Nacional Isiboro Secure en Bolivia.

Expression of Phorbol-12-myristate-13-acetate-induced protein 1 (PMAIP1) / Noxa correlates with survival in primary and metastatic human breast cancer.
Authors: Mamoor Shahan
Published: March 2020

Women diagnosed with stage I breast cancer have a 99% 5-year survival rate while women diagnosed with stage IV metastatic breast cancer that has spread beyond the breast are presented with a 27% 5-year survival rate (1). There are limited treatment options available for women diagnosed with metastatic breast cancer. Understanding how gene expression differs in patients that are longer survivors of breast cancer can facilitate target discovery for novel therapeutics. In this study we compared the transcriptomes of primary tumors from patients with breast cancer based on survival at 24 months and identified phorbol-12-myristate-13-acetate-induced protein 1 (2), PMAIP1, also known as Noxa (3) as among the most differentially expressed genes the tumors of women that survived past 24 months versus those that expired before 24 months. Transcriptome comparison using an independent dataset, this from the metastatic tissues of patients with stage IV breast cancer again identified PMAIP1/Noxa as differentially expressed based on survival at 24 months (4). In both cases, PMAIP1 was expressed at significantly higher levels in the tumors of survivors. PMAIP1 is member of the BCL-2 family of proteins that regulate apoptosis, a type of cell death (5, 6). These data demonstrate that PMAIP1 expression is positively correlated with survival and together with the molecular function of PMAIP1 suggest that increased PMAIP1 expression in the tumors of patients with enhanced survival of metastatic breast cancer might function to promote cell death of tumor cells. Modulation of PMAIP1 expression may be a relevant therapeutic strategy in patients with breast cancer.

Reinforcement learning guides food decisions, yet how the brain learns from taste in humans is not fully understood. Existing research examines reinforcement learning from taste using passive condition paradigms, but response-dependent instrumental conditioning better reflects natural eating behavior. Here, we examined brain response during a taste-motivated reinforcement learning task and how measures of task-based network structure were related to behavioral outcomes. During a functional MRI scan, 85 participants completed a probabilistic selection task with feedback via sweet taste or bitter taste. Whole brain response and functional network topology measures, including identification of communities and community segregation, were examined during choice, sweet taste, and bitter taste conditions. Relative to the bitter taste, sweet taste was associated with increased whole brain response in the hippocampus, oral somatosensory cortex, and orbitofrontal cortex. Sweet taste was also related to differential community assignment of the ventromedial prefrontal cortex and ventrolateral prefrontal cortex compared to bitter taste. During choice, increasing segregation of a community containing the amygdala, hippocampus, and right fusiform gyrus was associated with increased sensitivity to punishment on the task’s posttest. Further, healthy BMI was associated with differential community structure compared to overweight and obese BMI, where high BMI reflected increased connectivity of visual regions. Together, results demonstrate that network topology of learning and memory regions during choice is related to avoid a bitter taste and that BMI is associated with increased connectivity of area involved in processing external stimuli. Network organization and topology provides unique insight into individual differences in brain response to instrumental conditioning via taste reinforcers.
Mindfulness-based relapse prevention trial for compulsive sexual behaviour disorder
Authors: Holas Pawel , Draps Małgorzata , Kowalewska Ewelina , Lewczuk Karol , Gola Mateusz
Published: March 2020

Background and aims: Compulsive sexual behaviour disorder (CSBD) is a medical condition that can impair social and occupational functioning and lead to severe distress. To date, treatment effectiveness studies of CSBD are under-developed; typically, treatment for CSBD is based on guidelines for substance or other behavioural addictions. Mindfulness-based relapse prevention (MBRP) is an evidence-based treatment for substance addiction aimed at, among other things, reducing craving and negative affect—i.e. processes that are implicated in the maintenance of problematic sexual behaviours. However, to our knowledge no prior research has been published evaluating mindfulness-based intervention in the treatment of CSBD, except two clinical case reports. Therefore, the aim of the current preliminary research was to examine whether MBRP can lead to clinical improvement in CSBD. Methods: Participants were 13 adult males with a diagnosis of CSBD. Before and after the eight-week MBRP intervention, participants completed a booklet of questionnaires including measurements of porn viewing, masturbation and emotional distress. Results: As expected, we found that after MBRP participants spent significantly less time engaging in problematic pornography use and exhibited a decrease in anxiety, depression and obsessive-compulsive symptoms. Discussion and Conclusions: The findings indicate that MBRP could be beneficial for CSBD individuals. Further clinical effectiveness studies with bigger sample sizes, delayed post-training measurements and randomised control trial design are warranted. In conclusion, MBRP leads to a decrease in time spent watching porn and a decrease in emotional distress in CSBD patients.

Published: March 2020

The COVID-19 pandemic restricts people’s activities and makes consumer businesses suffered. This study explored the relationship between the perceived severity of COVID-19 and the post-pandemic consumption willingness. Study 1 surveyed 1464 Chinese people in March 2020, found the perceived severity of COVID-19 during the pandemic significantly increased the willingness to consume post-pandemic, and boredom stemming from limited activities and sensation-seeking expressions mediated this effect. Study 2 conducted an experiment with 174 participants in August 2020, found a high level of perceived severity of COVID-19 and the experience of life tedium during the pandemic significantly increased individuals’ impulsive buying tendencies after the pandemic. The results suggested the level of perceived severity of COVID-19 may influence people’s post-pandemic consumption patterns.
Network Analysis Reveals Central Symptoms of Adolescent Depression and Anxiety in Sub-Saharan Africa

Published: March 2020

Adolescent depression and anxiety—which are linked with many negative life outcomes—are prevalent around the world, particularly in low-income countries such as those in Sub Saharan Africa (SSA). We used network analysis to examine the topology, stability, and centrality of depression and anxiety symptoms. We analyzed data from a large community sample (N = 2,192) of Kenyan adolescents aged 13-18, using the Patient Health Questionnaire and the Generalized Anxiety Disorder Screener. We identified the central symptoms of the depression and anxiety symptom networks, and we compared the structure and connectivity of these networks between low-symptom and elevated-symptom sub-samples. Our findings indicate the most central depression symptoms were “self-blame” and “depressed mood”, while the strongest depression symptom associations were “self-blame” ––“depressed mood” and “trouble concentrating” ––“little interest/pleasure”. Similarly, the most central anxiety symptoms were “too much worry” and “uncontrollable worry”, while strongest anxiety symptom associations were “too much worry” ––“uncontrollable worry” and “trouble relaxing” ––“restlessness”. We found a statistical difference in the network structure between low-symptom and elevated-symptom adolescents. The low-symptom sample had higher network connectivity scores for both depression (global strength difference = 0.30; low-symptom = 0.49; high-symptom = 0.19; p = .003) and anxiety symptoms (global strength difference = 1.04; low-symptom = 1.57; high-symptom = 0.53; p < .001). This is the first report that uses network analysis techniques to identify central symptoms of adolescent depression and anxiety in SSA. Our findings illustrate how network analysis may inform understanding of psychopathology within cultures and suggest promising treatment targets.
Perceptual decision-making in children: Age-related differences and EEG correlates
Authors: Manning Catherine , Wagenmakers Eric-Jan , Norcia Anthony , Scerif Gaia , Boehm Udo
Published: March 2020

Children make faster and more accurate decisions about perceptual information as they get older, but it is unclear how different aspects of the decision-making process change with age. Here, we used hierarchical Bayesian diffusion models to decompose performance in a perceptual task into separate processing components, testing age-related differences in model parameters and links to neural data. We collected behavioural and EEG data from 96 six- to twelve-year-olds and 20 adults completing a motion discrimination task. We used a component decomposition technique to identify two response-locked EEG components with ramping activity preceding the response in children and adults: one with activity that was maximal over centro-parietal electrodes and one that was maximal over occipital electrodes. Younger children had lower drift rates (reduced sensitivity), wider boundary separation (increased response caution) and longer non-decision times than older children and adults. Yet model comparisons suggested that the best model of children’s data included age effects only on drift rate and boundary separation (not non-decision time). Next we extracted the slope of ramping activity in our EEG components and covaried these with drift rate. The slopes of both EEG components related positively to drift rate, but the best model with EEG covariates included only the centro-parietal component. By decomposing performance into distinct components and relating them to neural markers, diffusion models have the potential to identify the reasons why children with developmental conditions perform differently to typically developing children - and to uncover processing differences inapparent in the response time and accuracy data alone.

Individuals and institutions around the world have been affected by the Coronavirus Disease 2019 (COVID-19). Herein, we investigate the role of basic (Big Five and HEXACO) and specific (Dark Factor of Personality, Narcissistic Rivalry and Admiration) personality traits for 17 criteria related to COVID-19, grouped into (i) personal perceptions in terms of risks and worries about the disease, (ii) behavioral adjustments in terms of following health recommendations and hoarding, and (iii) societal evaluations in terms of the appropriateness of different measures and feelings of social cohesion. (Internal) Meta-analytic results across five samples from two countries (overall N = 19,718) show—next to gender and age effects—the importance of several traits, including Emotionality/Neuroticism for personal perceptions and anti- or prosocial traits for behavior in line with health recommendations. The investigation highlights the importance of individual differences in uncertain and changing situations in general and during the COVID-19 pandemic in particular.
Best Linear Unbiased Prediction of Latent Means in Three-level Data
Authors: AYDIN Burak , Algina James
Published: March 2020

In multilevel modeling decomposing variables into between and within components is often required in the analysis. This decomposition should not ignore the possible unreliability of an observed group mean (i.e. arithmetic mean) that is due to small cluster sizes and can lead to substantially biased estimates. Adjustment procedures that allow unbiased estimation have been defined and implemented in software for two-level model. This study introduces a two-stage adjustment procedure to implement the procedure for balanced three-level data and shows how to obtain information necessary for calculating adjusted means in unbalanced designs. A simulation study showed that the adjustment procedure provides unbiased estimates. An illustration is also provided to demonstrate how the adjustment procedure can change results in a real data context.

Parenting experiences are hypothesized to provide a lasting basis for adaptive socialization, but little is known about the relationship between parenting characteristics and daily-life social interactions. Adolescent and young adult twins and their siblings (N = 628) completed the Parental Bonding Instrument and a six-day Experience Sampling period to gather information on their daily-life social interactions. Higher overall parental bonding quality related to more positive social experiences in daily life, but not to different levels of social behaviors. Relative to maternal dimensions, paternal dimensions were uniquely predictive of better subjective social experiences. These findings demonstrate that specific aspects of parental bonding have unique effects upon how adolescents experience their social world, thereby making the idea of socialization through parenting relevant at the level of daily life.

The effect of the probiotic preparation Vetom 1.2 on the basis of Bacillus subtilis VKPM B-10641, Bacillus amyloliquefaciens VKPM B-10642 and Bacillus amyloliquefaciens VKPM B-10643 in different doses on the correlation interactions between the parameters of turkey hemoglobin exchange, blood erythrocytes and blood red blood cells direct and total bilirubin, total protein and serum albumin was studies. Correlations were calculated using Spearman formula, the reliability of correlations was checked by Student. The formulation was used for turkeys once a day for 30 days in doses of 12.5; 25; fifty; 75 and 100 mg / kg body weight. It was found that Vetom 1.2 in minimal doses leads to an inverse correlation between iron and total bilirubin, direct bilirubin, total protein and albumin, an increase in the concentration of the formulation leads to the disappearance of this effect with a gradual subsequent decrease in this indicator. Vetom 1.2 in doses up to 50 mg / kg leads to an inverse correlation between the concentrations of hemoglobin and direct bilirubin, total protein and serum albumin, at a dose of 75 mg / kg there is a direct correlation between these indicators, and at a dose of 100 mg / kg returns a negative correlation. The probiotic preparation Vetom 1.2 leads to a direct dependence of the concentration of bilirubins (total and direct) in serum on the concentrations of hemoglobin and red blood cells when used in most doses, except 75 mg / kg, which reduces the correlation.

Published: March 2020

The importance of photovoltaic-thermal (PV / T) collector systems in renewable energy technologies is increasing for combined hybrid electrical heat applications. The efficiency of photovoltaic (PV) systems varies between 5-20%. On average, 15% of the solar radiation coming to the PV panel surface is converted to electrical energy and the remainder is lost. In this study, a PV/T collector was designed using two different fluids simultaneously and its efficiency was calculated numerically. PV/T collector systems are specifically designed for agricultural production and their advantages are discussed. In this study, numerical calculations of PV/T collector with a different design have been made. The results were compared with reference to another experimental study. Two different working fluids (air and water) were used in the calculations. The system where air is used as working fluid is called Mode 1 and the system where water is used is called Mode 2. It is aimed to achieve high heat transfer by using water pipes, air ducts and fins placed under PV panels. In this way, it is aimed to produce a more stable hot air and water. In addition, in order to investigate the effect of flow on the yield, different flow rates were calculated. As a result of the theoretical analyses and calculations made in consideration of literature, the total efficiencies of air flow mode (Mode 1) were calculated as 43.2%, 46,2% and 48.7% at 0.0067 kg/s, 0.0072 kg/s and 0.0077 kg/s mass flow rates, respectively. For water flow mode (Mode 2), these values computed as 52.81%, 53.83% and 55.04% at 0.023 kg/s, 0.036 kg/s and 0.054 kg/s mass flow rates, respectively. It was found that PV / T collector efficiency increased with increasing end flow. Designed collector system is preferable in terms of effective use of energy and it can be easily applicable in processes such as hot air-water preparation, drying and greenhouse heating.

Published: March 2020

This paper presents the development and experimental verification of a generative CAD/FEM model of an external bone fixation device. The generative CAD model is based on the development of a parameterized skeleton algorithm and sub-algorithms for parametric modeling and positioning of components within a fixator assembly using the CATIA CAD/CAM/CAE system. After a structural analysis performed in the same system, the FEM model was used to follow interfragmentary fracture displacements, axial displacements at the loading site, as well as principal and Von Mises stresses at the fixator connecting rod. The experimental analysis verified the results of the CAD/FEM model from an aspect of axial displacement at the load site using a material testing machine (deviation of 3.9 %) and the principal stresses in the middle of the fixator connecting rod using tensometric measurements (deviation of 3.5 %).The developed model allows a reduction of the scope of preclinical experimental investigations, prediction of the behavior of the fixator during the postoperative fracture treatment period and creation of preconditions for subsequent structural optimization of the external fixator.
The concept of species in poplars (genus Populus L., Salicaceae) based on the example of the subgenus Tacamahaca (Spach) Penjkovsky representatives growing in Russia and neighbouring countries
Authors: Nasimovich Yuri , Kostina Marina , Vasilieva Natalia
Published: March 2020

Using the traditional research methods, based on the example of local and cultivated representatives of the Tacamahaca (Spach) Penjkovsky subgenus growing in Russia and neighboring countries, the concept of a species in poplars (genus Populus L., Salicaceae) has been developed. It is suggested that the sections of black poplars (Aigeiros Duby) and balsamic poplars (Tacamahaca Spach) in Eurasia form a single supraspecific system with a common gene pool, which is very similar to syngameon. The taxonomic species that make up such a system are different dynamic states of this system and exist in the equilibrium state between natural selection, which forms and preserves the specifics of each dynamic state, and gene flows from other taxonomic species. Such a system can also be considered as a large Linnaean species represented by many subspecies or even geographical and ecological races. The use of molecular genetic methods for the taxonomic species study in the Populus genus is difficult due to the powerful flow of genes between the species, since the species differ in a small number of genes responsible for adaptive characters. The sections of the subgenus Tacamahaca poplars are ecological. The combination of species in these sections is not so much about the unity of their origin, but about the common growing conditions: black poplars tend to grow in lowlands, while the balsamic poplars tend to grow in the mountains, with which the poplars’ diagnostic characters are associated. In nature, belonging to a certain section is more profitable than the intermediate state, but in cultivation and in the urban environment, the opposite situation is observed.

Published: March 2020

Species composition and ecology of the epiphytic lichens collected on 31 species of the trees and shrubs at the rural settlements and their surrounding area were studied. In total 71 lichens species including 25 species on the fruit and berry crops were found. On many trees, even in forests the variety of species of lichens is strongly depleted. This is especially true for rural settlements, razing places, keeping and running cattle. Bryoria and Usnea species at the rural settlements and their surrounding area were not found. It was shown that G. scripta is a pioneer species on the speckled alder under the conditions of relatively strong shading and humidity.
The Current State of the Gamification in E-Learning
Authors: Rozman Tomislav , Donath Liliana
Published: March 2020

The aim of this article is to present a systematic literature review of literature reviews (a meta-study) of gamification topics in e-learning with a purpose to present a high-level overview of the state of the development of the selected field.

The systematic literature review of literature reviews (2010 - 2019) was performed. The academic papers (literature reviews) from several academic databases such as DOAJ, ScienceDirect, Google Sholar and WOS were examined and filtered for further study. The selected articles were analysed for sub-topics (e.g. the efficiency of gamification mechanisms) and summarized.

In last 5 years, the research of gamification in various fields (mobile apps, e-health, human resource management, business development, e-learning) is getting traction and the number of research articles and systematic reviews of research articles is increasing. After filtering literature review articles, we have found out that only a handful of them – 19, which summarizes 2631 studies, are directly related to gamification in e-learning.

This study shows that the following gamification mechanisms in e-learning proved themselves efficient in almost all underlying studies, but there is no broad consensus on terminology and how to group of different gamification related concepts.

The research is limited to the following scholarly databases: DOAJ, Elsevier, Google Scholar, and WOS. We are aware that there is a possibility we missed some systematic literature reviews on this topic, which was indexed in other well-known databases or published using different terminology in the title or abstract.

The article can serve as a starting point for the research for the scholars and especially post-graduate students who are getting familiar with the e-learning, gamification and performing systematic literature reviews. Also, developers of e-learning systems and course designers could benefit from this article by finding out which gamification mechanisms are most researched, most efficient and worth implementing.

To our knowledge, this kind of meta-analysis of the literature reviews hasn’t been done in the field of gamification in e-learning for the year 2019.
The Impact of Personality Dimensions on Study Behaviour and Study Attitudes of Online Students
Authors: Divjak Marko , Prevolnik Rupel Valentina , Bartolj Tjaša
Published: March 2020

The objective of this study was to evaluate the impact of the Big Five personality dimensions on study attitudes and study behaviour of online students. Based on theoretical background, we proposed and tested the model, which assumes significant direct impact of personality dimensions on study attitudes and study behaviour and a bi-directional relationship between study attitudes and study behaviour.

Partial analyses of the interrelationships proposed in the model showed that personality dimensions exert a more powerful direct impact on study behaviour than on study attitudes, with conscientiousness being the strongest predictor of study behaviour. When personality dimensions are controlled, there is a significant moderate interrelationship between study behaviour and study attitudes. This indicates that personality dimensions may influence study attitudes indirectly via study behaviour. The results of structural equation modelling (SEM) revealed insufficient empirical evidence to support the model as a whole, which questions the validity of the proposed model.

Authors: Demchuk M. B. , Groshovyi T. A. , Malanchyk N. V.
Published: March 2020

The development of medical films containing active substances immobilized on polymeric carriers become significantly popular in the world. Medical films belong to the application forms and designed for injection of active pharmaceutical ingredients through the skin, periodontal tissue, the mucous membrane of the mouth. There are transdermal therapeutic systems, including buccal, dental and oral films. Pharmaceutical manufacturers present a wide range of medicinal films containing various active ingredients on the world market.

The purpose of our study was to conduct a comparison of the range of medicines in the form of medical films registered in the pharmaceutical markets of Ukraine, USA, and Poland. The object of the study was information on registered drugs in Ukraine, the USA, and Poland. The applied methods of study include generalization, systematization, and comparative analysis.

The range of medicinal films presented in the pharmaceutical markets of Ukraine, the USA, and Poland is analyzed. It is found that as of November 2019, there were 24 medicinal films registered in Ukraine, 70 medicinal films in Poland, and 104 medicinal films in the USA. Medicines in the form of transdermal therapeutic systems or patches have been registered in the pharmaceutical market of Ukraine. No buccal and oral drug films have been registered. In the Ukrainian market medicinal films are exclusively represented by foreign manufacturers from Germany (65%), Ireland (10%), Belgium (10%), Greece (5%), United Kingdom (5%), and the United States (5%).

The largest range of medical films is presented in the USA: 89.2% transdermal films, 7.8% – buccal films, 2.9% – oral films. In the Polish market, transdermal therapeutic systems also account for the largest share, with only 3% of the range being buccal films. In this study, we found that the active substances such as fentanyl, buprenorphine, estradiol, nicotine, nitroglycerin, rivastigmine, rotigotine, testosterone, scopolamine, oxybutynin, and others are most often introduced into drug films. It is found that in the US market the share of domestic manufacturers of medical films is 55.79%. Ukrainian pharmaceutical manufacturers do not offer medical films, which is a prerequisite for the development of those domestic dosage forms.

Objectives. Menthol causes a cooling sensation and reduces the nerve activity when it is applied locally, ingested, or inhaled. This feature explains its extensive use as both an aromatizer and a flavoring agent in food manufacturing, tobacco industry, cosmetics production, as well as a mild anesthetic and antiseptic in dentistry. This work aimed to perform a comprehensive thermodynamic study of L-menthol in both crystalline and gaseous states.

Methods. To determine the combustion energy of L-menthol in the crystalline state, combustion bomb calorimetry was used. The temperature dependence of L-menthol’s heat capacity in the range of 5–370 K and the melting (fusion) parameters were determined using adiabatic calorimetry. Quantum chemical calculations were performed on a standalone virtual machine in the Google Cloud Platform using an eight-core Intel Xeon Scalable Processor (Skylake) with a 2.0 GHz (up to 2.7 GHz at peak load) clock frequency and 8 GB RAM.

Results. The energy and enthalpy of L-menthol combustion in the crystalline state were determined, and the standard enthalpy of L-menthol formation in the gaseous state was calculated using the standard enthalpy of sublimation. The standard thermodynamic functions (reduced enthalpy, entropy, and reduced Gibbs energy) of L-menthol in both crystalline and liquid states were obtained based on the smoothed values of heat capacity and melting parameters. The group of isodesmic reactions for the ab initio calculation of the enthalpy of formation for gaseous L-menthol was substantiated. Electronic energy and frequencies of normal modes of the molecules involved in these reactions were calculated using the Gaussian 4 composite quantum chemical method. Further, the sublimation enthalpy of L-menthol was calculated using the extended Politzer equation according to the electrostatic potential model.

Conclusions. The first comprehensive thermodynamic study of L-menthol in various states of aggregation was performed, and the values calculated using semiempirical methods were consistent with the experimental values within error limits, which confirms the reliability of the results.

Objectives. Gene therapy is based on the introduction of genetic material into cells, tissues, or organs for the treatment of hereditary or acquired diseases. A key factor in the success of gene therapy is the development of delivery systems that can efficiently transfer genetic material to the place of their therapeutic action without causing any associated side effects. Over the past 10 years, significant effort has been directed toward creating more efficient and biocompatible vectors capable of transferring nucleic acids (NAs) into cells without inducing an immune response. Cationic liposomes are among the most versatile tools for delivering NAs into cells; however, the use of liposomes for gene therapy is limited by their low specificity. This is due to the presence of various biological barriers to the complex of liposomes with NA, including instability in biological fluids, interaction with serum proteins, plasma and nuclear membranes, and endosomal degradation. This review summarizes the results of research in recent years on the development of cationic liposomes that are effective in vitro and in vivo. Particular attention is paid to the individual structural elements of cationic liposomes that determine the transfection efficiency and cytotoxicity. The purpose of this review was to provide a theoretical justification of the most promising choice of cationic liposomes for the delivery of NAs into eukaryotic cells and study the effect of the composition of cationic lipids (CLs) on the transfection efficiency in vitro.

Results. As a result of the analysis of the related literature, it can be argued that one of the most promising delivery systems of NAs is CL based on cholesterol and spermine with the addition of a helper lipid DOPE. In addition, it was found that varying the composition of cationic liposomes, the ratio of CL to NA, or the size and zeta potential of liposomes has a significant effect on the transfection efficiency.

Conclusions. Further studies in this direction should include optimization of the conditions for obtaining cationic liposomes, taking into account the physicochemical properties and established laws. It is necessary to identify mechanisms that increase the efficiency of NA delivery in vitro by searching for optimal structures of cationic liposomes, determining the ratio of lipoplex components, and studying the delivery efficiency and properties of multicomponent liposomes.

Objectives. This study aims to establish the available porosity of a sorbent based on carbonized rice husk and investigate its sorption properties for oil and oil products.

Methods. A rice-husk-based sorbent carbonized at 400°С for 30 min was selected as the subject. The porosity of this sorbent is analyzed with the help of mercury porosimeters, the Pascal 140 EVO and Pascal 240 EVO. The sorption properties of the sorbent are also studied when cleaning water containing oil and oil products.

Results. The test sample is a bulk porous material with a pore volume of 0.015 cm/g; porosity higher than 15% was found, and the pore size distribution is shown. Studies were conducted on the sorption of oil and oil products as well as the possibility of using the aforementioned sorbent as a filtering material in the purification of water containing oil products. We investigated the sorption processes under dynamic and static conditions. The methodology for measuring the porous structure of solid materials on the mercury porosimeter, Pascal 140 EVO, was examined. The texture characteristics of the sorbent’s porous structure were determined, which is primarily the total volume of pores, the values of the specific surface area, and the volume of the microspores and mesopores.

Conclusions. The materials studied can be used as sorbents with a developed porous structure for purification of water with dissolved and emulsified petroleum products.

MPPT VOLTAGE REGULATING IN THREE-PHASE GRID-CONNECTED PHOTOVOLTAIC SYSTEM
Authors: Tran Tho Quang , Truong Anh Viet
Published: March 2020

The paper presents the method of harmonic attenuation with better dynamic response in the three-phase grid-connected photovoltaic system by using Maximum Power Point Tracking (MPPT) voltage regulator with varied increment. Since electrical power of PV array depends on the climatic condition. Maximum Power Point Trackers are used to extract maximum energy from photovoltaic generators. In this paper, every time the amount of electrical power generated by solar arrays changes continuously with weather conditions, MPPT voltage is regulated quickly with large increment to decrease dynamic response time, and then with small increment to get lower current THD. The simulation results in Simulink/Matlab show that the proposed MPPT voltage regulator with varied increment is better than with fixed.
