Evaluation of characteristics for microwave-assisted polymer coating of the steel substrate
Authors: Loharkar Praveen Kumar , Ingle Asha
Published: April 2023

Polymeric barrier coatings are one of the most sought-after methods for protecting metallic parts from corrosion and for ensuring a glossy appearance. In this work, pure polyester barrier coating was applied on a steel substrate using a microwave-assisted curing process with an experimental design based on L9 Taguchi orthogonal array. It included three key factors, viz. voltage, powder output from the spray gun and microwave power with three levels of each. The heat required for curing was achieved through electromagnetic-thermal energy conversion with the aid of a graphite susceptor. A multi-physics numerical study was carried out to identify the magnitude of temperature attained at different levels of microwave power and irradiation time. This was used to build the microwave curing set-up. The impact of parametric variation of the microwave-assisted process on the gloss was quantified. In addition, an assessment of dry film thickness, corrosion resistance, and impact strength was performed. Taguchi analysis reveals that out of three factors used, microwave power has the most significant impact on the gloss units. The desired level of impact strength was achieved for all samples, with the exception of the one coated with the factor combination of the least levels. Corrosion resistance for specimens was measured to be 240 h using a standard salt spray test. Specimen prepared with larger power input showed lesser blistering. The results substantiate the feasibility of a microwave-assisted process route for the industrial coating process.
Migrant bilingual youth, family, and school language policy: ethnographic insights for urban Quechua education
Authors: Kvietok Frances
Published: April 2023

In this paper, I draw on the ethnography of language planning and policy to consider how urban Indigenous language education might benefit from understanding the meanings and processes behind other language planning and policy activities migrant youth participate in, specifically, family language policymaking activities. Drawing on ethnographic fieldwork and interviews conducted in the region of Cusco, Perú I examine the experiences of two youth from rural hometowns and of their families. My analysis discusses how family language policies influenced youth’s shifting repertoires towards and away from Quechua, how youth drew on their Quechua–Spanish bilingualism to act as family language policy agents guided by local crianza and raciolinguistic ideologies, and how youth experienced Quechua language education in urban high schools. I argue that urban Quechua education efforts need to consider how migrant youth experience and shape their bilingualism and that of their families across rural-urban continua in order to craft safe and meaningful spaces where youth can participate in the strengthening of their Quechua language practices and identities.
On the “Imagination Consumption” of Film in the Internet Age
Authors: Chen Xuguang
Published: April 2023

The discussion regarding artistic imagination, and the artist’s subjective imagination, has long been an important issue for Chinese and foreign art theories. In the Internet Age, film imagination and “imagination consumption” show new features such as the fantasy of surreality, virtual reality, simulacra, and the aesthetics of “post-conditional theatre”. Films in the Internet age enrich the theory of film industrial aesthetics with fruitful practices. The article concludes with four types of film styles relevant to the “imagination consumption”: first, films which include modes of surreality, the aesthetic of conditional theatre and allegory; second, films from the mysterious fantasy and magic genres; third, films from the science fiction genre; and fourth, films from the film-game convergence genre. This article further notes the connection between such films, the dependence upon simulacra by today’s youth audience, and their demand for “imagination consumption”, suggesting the approach of the age of “imagination consumption”.
Critical Review of National Flood Policy Outcomes
Authors: Stanley Michelle , Hotard Abbey , Pilgreen Daniel , Meyer Michelle
Published: April 2023

Populations are increasingly exposed to natural hazards due to expanding development and climate change. This exposure is exacerbated by sociodemographic and socioeconomic factors limiting resources for disaster mitigation and recovery. Federal disaster assistance is crucial for communities in the wake of catastrophic events by supplementing local resources. However, recent research suggests that federal disaster assistance may exacerbate existing inequality across social groups. The most pervasive and costliest disaster in the United States is flooding. The federal government maintains multiple programs supporting flood mitigation and recovery, yet a comprehensive understanding of how these programs may foster inequitable outcomes is lacking. This paper uses a systematic review of federal flood policy literature over the last decade to fill this gap and identify patterns that may contribute to inequitable outcomes. Results suggest that despite over 100 flood-related disasters occurring over the past decade, the effectiveness of flood policies across social groups is relatively unstudied. And when studied, federal policies themselves do not explicitly lead to inequitable outcomes. Instead, we conclude that policies prioritize equality over equity and do not overcome systematic oppressive and racist decision-making. These findings further the understanding that social vulnerability to natural hazards is a complex and contextual issue.
Male-pattern hair loss: Comprehensive identification of the associated genes as a basis for understanding pathophysiology
Authors: Henne Sabrina K. , Nöthen Markus M. , Heilmann-Heimbach Stefanie
Published: April 2023

Male-pattern hair loss (MPHL) is a highly heritable and prevalent condition that is characterized by progressive hair loss from the frontotemporal and vertex scalp. This androgen-dependent hair loss may commence during puberty, and up to 80 % of European men experience some degree of MPHL during their lifetime. Current treatment options for MPHL have limited efficacy, and improved understanding of the underlying biological causes is required to facilitate novel therapeutic approaches. To date, molecular genetic studies have identified 389 associated genomic regions, have implicated numerous genes in these regions, and suggested pathways that are likely to contribute to key pathophysiological mechanisms in MPHL. This review provides an overview of the current status of MPHL genetic research. We discuss the most significant achievements, current challenges, and anticipated developments in the field, as well as their potential to advance our understanding of hair (loss) biology, and to improve hair loss prediction and treatment.
Genetic underpinnings of the psoriatic spectrum
Authors: Hüffmeier Ulrike , Klima Janine , Hayatu Mohammad Deen
Published: April 2023

The psoriatic field includes both rare and common subtypes. Common complex forms include psoriasis vulgaris and psoriatic arthritis. In these subtypes, certain HLA alleles remain the most relevant genetic factors, although genome-wide association studies lead to the detection of more than 80 susceptibility loci. They mainly affect innate and adaptive immunity and explain over 28 % of the heritability. Pustular psoriasis comprises a group of rarer subtypes. Using exome sequencing, several disease genes were identified for mainly generalized pustular psoriasis, and an oligogenic inheritance is likely. Treatment studies based on the affected IL–36 pathway indicate a high response rate in this subtype further supporting the pathophysiological relevance of the affected gene products.
Auslaufmodell verminderte Schuldfähigkeit? Die Dichotomisierung der Neuanordnungen gem. §§ 63/64 Strafgesetzbuch
Authors: Querengässer Jan , Traub Hans-Joachim
Published: April 2023

Mit den freiheitsentziehenden Maßregeln der Besserung und Sicherung ist die Frage der Schuldfähigkeit im deutschen Strafrecht normativ eng verknüpft. Für die Anordnung einer Unterbringung im psychiatrischen Krankenhaus gem. § 63 StGB stellen Schuldunfähigkeit oder verminderte Schuldfähigkeit (gem. §§ 20/21 StGB) eine Voraussetzung dar; eine Unterbringung in der Entziehungsanstalt gem. § 64 StGB kann unabhängig von der Feststellung individueller Schuld und somit in Kombination mit §§ 20 oder 21 StGB oder auch ohne Einschränkung der Schuldfähigkeit angeordnet werden.

Der vorliegende Artikel beschreibt und analysiert die Entwicklung der Neuanordnungen entsprechender Schuldfähigkeits-/Maßregelkombinationen in den Jahren 1995 bis 2018 auf Grundlage der Strafverfolgungsstatistik und nutzt dafür lineare und polynome Trendmodelle. Neben der absoluten und relativen Gesamtverteilung werden auch einzelne Populationsparamater der Subgruppen im Zeitverlauf verglichen.

In beiden Sanktionen nahm der Anteil an verminderter Schuldfähigkeit deutlich ab und lag zuletzt jeweils bei unter 30%. Es überwiegen zunehmend die Kombinationen aus §§ 63/20 StGB bzw. § 64 StGB und voller Schuldfähigkeit. Bei ergänzender Betrachtung von Populationsparametern imponieren je nach Schuldfähigkeitsstufe differenzielle Entwicklungen. Am deutlichsten zeigt sich dies bei § 64 StGB und Vergehen gegen das BtMG: Während sich bei voll Schuldfähigen der Anteil derartiger Hauptdelikte auf über 40% verdoppelt, halbiert er sich bei vermindert Schuldfähigen auf unter 10%.

Die möglichen Ursachen und Implikationen dieser Entwicklungen werden vor dem Hintergrund von allgemeinen Veränderungen in Epidemiologie und Deliktgeschehen diskutiert. Plausibel erklärbar wird das Ausmaß indes nur als Effekt einer geänderten Rechts- und Begutachtungspraxis. Die beobachtete Dichotomisierung der Neuanordnungen kann somit auch als vorweggenommene Neuordnung des Sanktionenrechts durch die Rechtspraxis interpretiert werden.

Published: April 2023

In most intermetallic europium compounds, the Eu atoms exhibit a divalent oxidation state with a high effective magnetic moment since Eu2+ is isoelectronic with Gd3+. Trivalent intermetallic Eu compounds, in contrast, are extremely scarce and under 20 examples are known to literature. This mini-review summarizes the known binary and ternary examples along with their crystal-chemical peculiarities as well as their magnetic and 151Eu Mössbauer spectroscopic behavior. Additionally, compounds that exhibit valence phase transitions are summarized.
Bifurcation analysis of a discrete type prey-predator model with Michaelis–Menten harvesting in predator
Authors: Mortuja Md Golam , Chaube Mithilesh Kumar , Kumar Santosh
Published: April 2023

A discrete predator–prey model with square root functional response describing prey herd behavior and nonlinear predator harvesting has been considered in the present work. Three equilibria of the system have been found and observed that two equilibrium points always exist and are feasible, but the interior equilibrium point is feasible under a parametric condition. The local stability of the three equilibria has been analyzed. The interior equilibrium point is locally asymptotically stable under a parametric condition. It is examined that a flip and Neimark–Sacker bifurcations have occurred in the system at the axial equilibrium point. The flip and Neimark–Sacker bifurcations have been analyzed by the center manifold theorem and bifurcation theory, considering the harvesting coefficient as the bifurcation parameter. The proposed discrete model with a nonlinear Michaelis–Menten type harvesting effect on the predator population exhibits rich dynamics; for instance, bifurcations, chaos, and more complex dynamical behaviors. The discrete-time model also produced few numerical simulation results that are more accurate than the continuous model. The proposed discrete model will be performed better than the continuous model in populations with non-overlapping generations or smaller densities. The harvesting coefficient’s optimal value has finally been identified, and an optimal harvesting policy has been introduced. To verify the results, further numerical simulations have been performed.

Published: April 2023

Marketing is an extremely important element of any business, because in this way customers learn about the services offered, and this helps a given business entity achieve profits. Properly selected marketing tools not only allow the information function to be fulfilled, but also positive relationships with customers to be created and maintained. In addition to advertising, which is one of the most popular forms of marketing, the factors affecting a company's image include the quality and price of the products and services offered. Like all other business entities conducting their activities, banks use certain instruments to attract and retain customers. Almost everyone uses banking services, which is why it is important to stand out from the competition. The specificity of the functioning of banks differs from a company, because these institutions are subject to various restrictions, both domestic and international. In times of economic crisis, promotional activities are often decisive for the survival of a given entity on the market. The aim of this study was to discover customer opinions of marketing activities undertaken by banks. In their work, the authors made a characteristic of banking activity and brought closer the essence of banking marketing. Marketing instruments that are used in banking activities were also discussed. For the purposes of the article, the authors developed a survey questionnaire to perform consumer research on issues such as to what extent advertising affects the choice of a given bank's offer, which affects the bank's image as well as expectations towards these institutions.

Objective

The aim of this study isto assess the efficacy of a very low-calorie ketogenic diet (VLCKD) method vs a Mediterranean low-calorie diet (LCD) in obese polycystic ovary syndrome (PCOS) women of a reproductive age.

Design

Randomized controlled open-label trial was performed in this study. The treatment period was 16 weeks; VLCKD for 8 weeks then LCD for 8 weeks, according to the Pronokal® method (experimental group; n = 15) vs Mediterranean LCD for 16 weeks (control group; n = 15). Ovulation monitoring was carried out at baseline and after 16 weeks, while a clinical exam, bioelectrical impedance analysis (BIA), anthropometry, and biochemical analyses were performed at baseline, at week 8, and at week 16.

Results

BMI decreased significantly in both groups and to a major extent in the experimental group (−13.7% vs −5.1%, P = 0.0003). Significant differences between the experimental and the control groups were also observed in the reduction of waist circumference (−11.4% vs −2.9%), BIA-measured body fat (−24.0% vs −8.1%), and free testosterone (−30.4% vs −12.6%) after 16 weeks (P = 0.0008, P = 0.0176, and P = 0.0009, respectively). Homeostatic model assessment for insulin resistance significantly decreased only in the experimental group (P = 0.0238) but without significant differences with respect to the control group (−23% vs −13.2%, P > 0.05). At baseline, 38.5% of participants in the experimental group and 14.3% of participants in the control group had ovulation, which increased to 84.6% (P = 0.031) and 35.7% (P > 0.05) at the end of the study, respectively.

Conclusion

In obese PCOS patients, 16 weeks of VLCKD protocol with the Pronokal® method was more effective than Mediterranean LCD in reducing total and visceral fat, and in ameliorating hyperandrogenism and ovulatory dysfunction.

Significance statements

To the best of our knowledge, this is the first randomized controlled trial on the use of the VLCKD method in obese PCOS. It demonstrates the superiority of VLCKD with respect to Mediterranean LCD in reducing BMI with an almost selective reduction of fat mass and a unique effect of VLCKD in reducing visceral adiposity, insulin resistance, and in increasing SHBG with a consequent reduction of free testosterone. Interestingly, this study also demonstrates the superiority of the VLCKD protocol in improving ovulation, whose occurrence increased by 46.1% in the group treated by the VLCKD method against a rise of 21.4% in the group treated by Mediterranean LCD. This study extends the therapeutic approach possibilities in obese PCOS women.

Published: April 2023

Cada año, el número de muertes aumenta extremadamente debido al cáncer de mama. En 2020, la Organización Mundial de la Salud informó que el 25% de las mujeres fueron diagnosticadas con cáncer de mama. En Perú, el cáncer de mama fue la principal causa de muerte por cáncer, donde cada día mueren 5 mujeres por esta enfermedad. La detección temprana del cáncer de mama es facilitada por computadora tecnologías de detección y diagnóstico (CAD), que pueden ayudar a las personas a vivir vidas más largas. Este artículo busca analizar múltiples modelos de aprendizaje automático para identificar el cáncer de mama. Para esto, se trabaja con dos bases de datos de Wisconsin donados por el Dr. William H.

El principal objetivo de este trabajo es aprovechar los últimos desarrollos en sistemas CAD y metodologías relacionadas para las predicciones, los modelos de Decisión Tree, K-vecinos más cercanos (K-NN), Naive Bayes (NB), Regresión logística, Support Vector Machine, Multi-layer Perceptrón y Random Forest se utilizaron. Cuando se comparan los resultados, se encuentra que, para la base de datos del año 1995, el algoritmo Multi-layer Perceptron ofrece el mejor resultado, logrando una precisión de 97,20% y para la segunda base de datos de 1992, el algoritmo que mejor predice es el Support Vector Machine con una precisión de 97,20%.
Sudden Cardiac Death in Ischaemic Cardiomyopathy and the Primary Prevention ICD: Time for a More a Personalised Approach?
Authors: Ezad Saad M , Babu Girish , O’Kane Peter
Published: April 2023

Guidelines recommend primary prevention implantable cardioverter defibrillator (PPICD) for left ventricular ejection fraction (LVEF) <35% only after 3 months of optimal medical therapy (OMT) or 6 weeks after acute MI with persistent LVEF dysfunction. A 73-year-old woman presented with decompensated heart failure secondary to ischaemic cardiomyopathy. Severe coronary disease with sufficient dysfunctional myocardial segments on cardiac MRI suggested potential benefit from revascularisation. Following discussion with the heart team, she underwent percutaneous coronary intervention (PCI). PPICD implantation was deferred as per guideline recommendations. However, 20 days post-PCI, the patient died from malignant ventricular arrhythmia captured on a Holter monitor. This case demonstrates that some high-risk patients may not receive a potentially life-saving PPICD if guidelines are stringently adhered to. We highlight evidence that LVEF alone is of limited value in a risk assessment of arrhythmogenic death, and postulate that a more personalised ICD prescription should be considered using scar characteristics on cardiac MRI to prompt upstream ICD implantation in high-risk patients.
Problems and Improvements to Special Supply System of Housing
Authors:   The Institute of Legal Studies, Kyunghee University, Kim Ju-Hee
Published: April 2023

In order to solve the housing problem, Korea enacted a related legal system and implemented a system for the purpose of quantitative supply of housing. However, according to the seriousness of the housing problem and changes in the social environment, the paradigm of housing policy was changed from expanding the quantitative supply of housing to housing welfare, and the “Framework Act On Residence” was enacted in 2015. However, with the enactment of the “Framework Act On Residence” and the provision of housing rights, despite the need for housing to be discussed in the field of social security jurisprudence, housing-related legal systems are still being discussed from a political and policy perspective.
In the case of the special supply system of housing, one of the housing supply systems as a method of realizing housing welfare, it needs to be discussed more closely from the perspective of the social security jurisprudence because it is a housing supply method for social and policy considerations. Therefore, it is necessary to review the special supply system of housing according to the principle of the rule of law and the principle of the social state. However, the special supply system of housing has complex regulations on the subject, type, and requirements, and there is no definition of the subject. If the law is defined and the system is implemented without clear principles or norms, it will be impossible to accomplish the guarantee of the people's housing rights. Therefore, it is necessary to interpret and improve the system from the perspective of the housing welfare and social security jurisprudence to guarantee actual housing rights.
A Study on Family Reunification of the Child: Focusing on Case Law of the European Court of Human Rights
Authors:   The Institute of Legal Studies, Kyunghee University, Cho Jung-hyun , Lee Jiwon
Published: April 2023

Family unity and family reunification (or family reunion) are similar in that they deal with protection of family as one unit. However, since family reunification focuses on the maintenance of families that have already been formed but separated due to migration, these two concepts are not strictly regarded as the same ones. Family reunification is important as it promotes the stability and social integration of the people directly involved. In particular, for children, the necessity of applying the right of family reunification deserves special emphasis as an effective preventive measure against various kinds of risks they face. In Korea, it is difficult as yet to find cases or legislation dealing with family reunification of the child, however, there is a possibility of increasing the future occurrence of the issue due to continuous influx of foreigners.
Thus, this research attempts to provide a starting point for further discussions through reviewing international legal bases and introducing related case law of the European Court of Human Rights.
As a result, the research found that there is an international consensus to ensure the family reunification of the child on the basis of the Convention on the Rights of the Child, European Convention of Human Rights and other related documents. The case law of the ECtHR also provides two meaningful implications in this sense. First, it embodied the concept of the family reunification of the child by active consideration of universal and regional standards. The Court confirmed that the family reunification of the child means not only entry into, but also ensuring stable stay. In this regard, the Court recognized a related positive obligation of the authorities. In determining whether there is a violation of the obligations, the Court consistently considered a fair balance between individual and public interests. Second, the Court solidified its position that the best interests of the child should be given priority in all cases concerning children. In the trial processes, the Court comprehensively regarded several factors that may cause significant influence, such as the age of the children concerned, their situation in their country of origin and the extent to which they are dependent on their parents, and so on.
There may be some differences in family type and culture between Europe and Korea. Nevertheless, the introduction of somewhat advanced judgments from ECtHR is really meaningful in a situation where related discussions are not yet enough. It is expected that this study containing analysis of the European case law on family reunification of the Child would contribute to the improvement of related domestic case law and legislation, considering properly both national interests and human rights.

Purpose - to describe the possibilities of using a ketogenic diet (KD) in the pediatric population for therapeutic purposes in refractory seizure syndrome and congenital metabolic disorders. The historical aspects of the development of special medical nutrition to achieve stable ketosis in children for the treatment of seizures of various genesis are briefly highlighted; the development of the evidence base for the effectiveness of the KD in children is presented. A review of current data on the multifactorial mechanisms of neuroprotective effects of KD is carried out. In particular, individual ways of modulating fundamental biochemical pathways, presynaptic and postsynaptic changes in vesicular transport and release of excitotoxic and inhibitory substrates at synapses are considered. Four types of diets are described according to the distribution of proteins, fats, and carbohydrates: the classic, modified Atkins diet, medium-chain triglyceride diet, and low glycemic index diet. The indications and contraindications for the appointment of medical ketogenic dietary therapy are considered. The most appropriate age periods of childhood for the type of KD are outlined to achieve maximum effectiveness. The authors describe in detail the main objectives of the stages of preparation of the child and family for the start of dietary treatment, the principles of initiation of KD, laboratory and instrumental monitoring and discontinuation of ketogenic dietary therapy. Particular attention is paid to the issue of counseling a child before starting a KD, the main steps in calculating the proportion of macronutrients and the principles of daily nutrition. The possibilities of prescribing medical ketogenic dietary therapy outside of refractory seizures, in particular, in glucose transaminase 1 deficiency syndrome, pyruvate dehydrogenase deficiency, mitochondrial disorders, heart failure, and brain injury, are analyzed. Available special products for medical purposes (clinical nutrition) for the organization of medical ketogenic therapy in pediatric patients, especially in the first years of life, are presented. No conflict of interests was declared by the authors.

The use of home teleconsultation in outpatient pediatric practice has become widespread in many countries over the world, regardless of their economic situation. Each country has its own experience in the practical implementation of home teleconsultation in medical care for patients, but the issue of increasing its effectiveness remains topical. Purpose - to consider the issue of improving the efficiency and safety of home teleconsultation for children under 5 years old with fever. Materials and methods. The terms «home teleconsultation», «telemedicine sorting», «children», «fever» were searched using Pub Med Central databases. The data of the regulatory and legal protocols in Ukraine were taken into account while determining the recommendations. Results. Research in recent years proves that new forms of communication between a doctor and a patient, his parents or guardians create both additional opportunities and risks regarding various aspects of the quality of medical care. According to the data of literary sources, conclusions were made that the quality of home teleconsultation for children under 5 years of age is affected by: social and ethical features of communication with children and their parents; lack of standards/scenarios for telephone consultation for a specific pathology; lack of appropriate professional training of doctors. The article provides measures to improve home teleconsultation: the use of telesorting scenarios (NICE protocol/standard for children under 5 years with fever) using a «traffic light system», alarm symptoms («red flags») to predict the risk of serious illness and taking into account the availability of the use of the «safety net». There is a well-founded need for professional training of medical workers in the field of telemedical consultation. Conclusions. The implementation of home teleconsultation services in outpatient pediatric practice in situations where a child’s condition is assessed by a medical professional who cannot examine him because the child is geographically distant will contribute to a faster setting of priorities for the provision of primary medical care. In today’s environment, the NICE (2021) protocol/standard for the assessment and initial treatment of fever in children under 5 years of age is a clinical scenario that meets the requirements for home teleconsultation. The introduction of the leading international experience of organizing home teleconsultation for children under 5 years of age is the basis for improving programs of continuous professional experience of medical workers who provide assistance to children.

Acute hematogenous osteomyelitis is one of the common bacterial infections in children of early age, which is accompanied by mild symptoms at the initial stage of diagnosis. The onset of the disease is usually acute with fever, intoxication syndrome, focal signs of bone inflammation and limitation of limb function. Purpose - to show the features of diagnosis and treatment of acute hematogenous osteomyelitis in an infant based on clinical observation. Clinical case. The clinical case of a child of early age with acute hematogenous osteomyelitis, who was hospitalized with complaints of an increase in body temperature up to 40°C, restlessness, swelling and hyperemia of the lower part of the right thigh and right knee joint, and movement disorders in the right leg, was presented. The general condition of the child upon admission is severe due to intoxication, hyperthermic syndromes and local changes in the right lower limb, which was in a forced position, pronation. There were no active movements in the right leg, passives ones were painful. Rotational movements in the right leg are possible, but painful. The soft tissues in the area of the right hip and knee joints, as well as the thighs, were not changed in color, their swelling was noted. Conclusions. Symptoms of acute hematogenous osteomyelitis in young children are often nonspecific. Intoxication syndrome symptoms and local changes as movement disorders in the limb in children of this age group dominate. Pain can be detected during the examination, which is clearly localized with sensitivity over the infected bone; edema may be present. Changes of complete blood count are mild, while the determination of C-reactive protein during the initial evaluation can serve as a baseline value for sequential monitoring. The sensitivity of X-ray examination at the beginning of the disease is low, radiological changes appear only 7-21 days after infection. Empiric antimicrobial therapy aimed at Staphylococcus aureus should be prescribed immediately after the detection of acute hematogenous osteomyelitis clinical signs even before receiving results of additional research methods. The research was carried out in accordance with the principles of the Helsinki Declaration. The informed consent of the patient was obtained for conducting the studies.

In nature, prebiotics occur not only in fruits and vegetables but also in the seeds from fruits. This study focused on surveying the prebiotic property of the kernel fibers from eight Vietnam’s agro products which were jackfruit, avocado, rambutan, longan, durian, tropical almond, sesame, and lotus seeds. Kernels were investigated for total sugar, soluble protein, and fat contents. The highest total sugar content was found in lotus seed kernel (37.46%) but in kernels from sesame and tropical almond the value only was 2.42 and 3.07% respectively. Rambutan seeds had the highest fatty (54.3%) and soluble protein content (4.49%) while in kernel from durian had the lowest fatty (19.66%) and dissolved protein content (0.69%) among the studied seeds. Kernel powders were defatted, digested by enzymes: α – amylase, glucoamylase and neutrase, then extracted by 96% ethanol to obtain soluble fibers. The prebiotic potential of these fibers was investigated by the growth stimulation of four probiotic strains: Bifidobacterium animalis AP1.2, Bifidobacterium bifidum CNTP 6599, Lactobacillus casei PK2 and Lactobacillus fermentum SBV2. The highest increase of viable cells, compared to the control, was 0.52 lg (CFU/ml) found in medium supplemented with kernel fiber from longan, fermented by L. casei PK2. This fiber also stimulated the growth of four probiotics. However, the soluble fiber content obtained from longan seeds is the lowest among the types surveyed (0.02%). The fiber in jackfruit, avocado or lotus seeds also has a positive prebiotic index, except for L. fermentum SBV2, in which jackfruit and lotus seeds are still commonly used in Vietnamese life.

Nitrogen-fixing microorganisms (diazotrophs) converting the atmospheric N2 into usable form NH4 are considered the key players in the nitrogen cycle, chiefly responsible for the enriching nitrogen content in the soils. Globally, biological fixation of N2 greatly contributes to plant growth, lessens the need for chemical fertilizers, and thus contributes to the mitigation of greenhouse gases NOx. In this study, diazotrophic bacterial strains were isolated from rhizosphere soils and root nodules of legume and non-legume plants in Vietnam. Quantitative analyzes by the acetylene reduction assay showed that the isolates have high nitrogen fixation activity compared with that of reference strain Azospirillum vinelandii KCTC 2426. In addition, other effective capabilities of the isolated strains toward supporting agriculture were investigated, i.e. synthesizing IAA and siderophore for promoting plant growth, or producing exopolysaccharides for maintaining soil moisture. Taxonomic positions of the isolated strains were identified based on the comparative analyses of sequences of the 16S rDNA and gene related to nitrogen fixation (nifH), revealing a high taxonomic diversity among free-living and symbiotic diazotrophic isolates. Direct support of the selected isolates to plant growth was proven in experiments with mung beans under laboratory conditions. Thus, the native diazotrophic strains obtained in this study would be good microbial sources for application in organic agriculture and soil amendment.

A continuous development of glass-making on Ukrainian lands can be observed only from the end of the 10th century. At that time glass-making was exceptionally an urban craft. After the Mongol-Tatar invasion the arts were slightly declined, but starting from the middle of the 15th century glass-making revived in a somewhat different form: the workshops were located in the forest areas distant from the cities near the sources of raw materials. Such workshops were known as “huty” i.e. glassworks, this term took a Europe-wide meaning and denoted a building with a furnace in it. At the same time craftsmen continued to ply glass-making in the cities. The craftsmen entered workshops or worked independently if they lived in small towns. The workshop manufacturing process had its own characteristic features which certainly affected glass-making. As to the glassworks, glass-making was arranged in a totally different way there and thus the question of glass-making peculiarities in glassworks and workshops and the social and economic conditions of glassworks and workshop craftsmen becomes the matter of current interest.
