Cardiovascular disease is the leading cause of death in the Kingdom of Bhutan. Thus, the early detection and prevention of hypertension is critical for reducing cardiovascular disease. However, the influence of sociocultural factors on vulnerability to hypertension needs further investigation. This study performed secondary data analysis on 1,909 individuals in a cross-sectional study (the National survey for noncommunicable disease risk factors and mental health using World Health Organization (WHO) STEPS approach in Bhutan– 2014). Multivariate logistic regression demonstrated a significant association between gender with marital status and hypertension. Women had a higher odds ratio than men (Ref) when married (AOR: 1.27, 95% confidence intervals (CI): 1.23–1.31), and when separated, divorced, or widowed (AOR: 1.18, 95% CI: 1.12–1.26). People who speak the Tshanglakha language scored the highest odds (AOR: 1.24, 95% CI: 1.20–1.27), followed by Lhotshamkha (AOR: 1.09, 95% CI: 1.06–1.12) and Dzongkha (Ref) after adjusting for various social and biomedical factors. Additionally, tobacco use displayed decreased odds for hypertension. To promote the early detection and prevention of hypertension, these cultural factors should be considered even within small geographic areas, such as Bhutan. It is necessary to strengthen hypertension preventive strategies for people who speak Tshanglakha and Lhotshamkha. Furthermore, careful consideration should be given to preventing hypertension among adults aged 40 years or more, women who are married, separated, divorced, or widowed, and men who never married in Bhutan.

La presencia femenina en la revuelta de Espartaco: su recepción cinematográfica y televisiva
Authors: Lapeña Marchena Oscar
Published: August 2021

Son escasos los testimonios literarios que refieren la presencia de mujeres en la revuelta servil de Espartaco, ya sea como participantes de la misma o como romanas que padecen los efectos de la rebelión. Suelen estar asociadas a la presencia de cultos religiosos, destacando el episodio del sueño de Espartaco interpretado por su compañera conocedora de los cultos dionisíacos. En la rescritura que el cine y la televisión ha realizado del episodio, Espartaco se ha convertido en un trofeo sentimental y sexual por el que compiten por igual esclavas y romanas.

Notas sobre la presencia de Augusto en el Iter ab Emerita Astvricam: Acerca de dos miliarios de la provincia Lvsitania
Authors: Paredes Martín Enrique
Published: August 2021

Se ofrece un detallado estudio acerca de dos miliarios ya conocidos y procedentes, respectivamente, de las localidades de Ahigal y Coria (Cáceres, España). En el primer caso, nuestra reinterpretación nos lleva a descartar la atribución tiberiana que ha sido tradicionalmente propuesta para el miliario de Ahigal, señalando que en realidad nos hallamos ante un hito augusteo. En el segundo caso, tratamos de probar que, frente a las dudas expresadas por parte de ciertos investigadores, efectivamente nos hallamos ante un miliario de Augusto. En función de estas consideraciones, y proponiendo a modo de hipótesis la relación del miliario augusteo de Coria con el iter ab Emerita Asturicam, planteamos algunas ideas tratando de reevaluar el papel de Augusto en la comúnmente denominada Vía de la Plata.

Published: August 2021

Speech enhancement, which aims to recover the clean speech of the corrupted signal, plays an important role in the digital speech signal processing. According to the type of degradation and noise in the speech signal, approaches to speech enhancement vary. Thus, the research topic remains challenging in practice, specifically when dealing with highly non-stationary noise and reverberation. Recent advance of deep learning technologies has provided great support for the progress in speech enhancement research field. Deep learning has been known to outperform the statistical model used in the conventional speech enhancement. Hence, it deserves a dedicated survey. In this review, we described the advantages and disadvantages of recent deep learning approaches. We also discussed challenges and trends of this field. From the reviewed works, we concluded that the trend of the deep learning architecture has shifted from the standard deep neural network (DNN) to convolutional neural network (CNN), which can efficiently learn temporal information of speech signal, and generative adversarial network (GAN), that utilize two networks training.

L’informatique est une discipline exigeante à bien des niveaux, et son enseignement a suscité beaucoup de questionnements dans le domaine de la pédagogie. Quand s’ajoutent aux difficultés d’ordre disciplinaire, des éléments de complexité plus fort encore comme l’hétérogénéité d’un groupe d’étudiants (niveaux de compétences différents, formation et parcours professionnels différents, origines ethniques et culturelles différentes), les attendus des enseignants et des étudiants sont forcément mis à mal. Cet article propose l’évaluation d’un dispositif pédagogique par le jeu de rôle ayant pour but de prendre en compte les difficultés liées à l’altérité des étudiants et de permettre de les surmonter de manière ludique et motivante, en prenant en compte les spécificités de chacun au sein du groupe.
The Content Validity and Interrater Reliability of Nursing Outcome Classification Self-Care for Toileting among Children with Physical Disabilities
Authors: Meisyarah Yogi Hasna , Hartini Sri , Haryanti Fitri
Published: August 2021

Background: Nursing Outcome Classification (NOC) Self-care for Toileting is an instrument for measuring the abilities of toileting self-care among children with physical disabilities. However, there has been no cultural adaptation in the Indonesian context, especially among children with physical disabilities, so that the validity and inter-rater reliability of the instrument has not been reported. Testing the content validity and interrater reliability of this instrument is necessary so that it could be used to measure the ability of toileting self-care.Purpose: This study aimed to examine the content validity and inter-rater reliability of NOC Self-care for Toileting among children with physical disabilities.Methods: This was a descriptive quantitative non-experimental research with a cross-sectional design. In the content validity test, this study employed seven experts teaching in nursing academies with a minimum degree of S2/specialist and had the experiences in basic nursing to assess the validity of NOC Self-care for Toileting. As for the inter-rater reliability test, this study involved two raters of nursing students who have passed block 2.4 lecture on “Growth and Development” and 36 children with physical disabilities at a Special School in Bantul, Yogyakarta. The validity test was analyzed using CVR, CVI, and Aiken’s V indexes, while the inter-rater reliability test was analyzed using Kappa and percent agreement.Results: The validity test showed the CVR value range of 0.71-1.00, the CVI value of 0.91, and the V coefficient range of 0.86-1.00. In the inter-rater reliability test, the Kappa value obtained was 0.958, and the percent agreement value was 97.22% for all indicators of NOC Self-care for Toileting.Conclusion: NOC Self-care for Toileting is a valid and reliable instrument for measuring the abilities of toileting self-care among children aged 6-18 with mild to moderate degrees of physical disabilities. Further research can be conducted by involving different respondents and cultures with more than two raters if possible.

Published: August 2021

Background: Older adults are susceptible to worsened quality of life (QOL) and depression due to aging. Elderly integrated health service post (EIHSP) is community-based health care that aims to improve older adults’ health; however, not all older adults participate in this health service.Purpose: This study was conducted to assess the relationship between the QOL, depression level, and older adults’ participation in EIHSP.Methods: A cross-sectional study was carried out among 102 older adults in a community-dwelling area in Semarang, Indonesia. Respondents were recruited using a total sampling technique. QOL was assessed by the WHOQOL-BREF questionnaire, while the level of depression was assessed by Geriatric Depression Scale (GDS) questionnaires. Descriptive statistics, Spearman, and Sommers’ d tests were used to analyze the data.Results: Higher participation in EIHSP significantly affected QOL on every domain (general quality of life, physical, psychological, social relationship, and environmental domains) with p<0.05. This study also showed that participation in EIHSP had a significant relationship with depression levels (p=0.002). Furthermore, higher depression levels significantly affected QOL on every domain (p<0.05).Conclusion: This study showed that older adults’ participation in EIHSP had a significant relationship with QOL and depression. Community nurses can promote the utilization of EIHSP among older adults for better physical and mental health. Future studies should investigate these relationships in a larger sample size.
Revisiting Job Satisfaction and Intention to Stay: A Cross-sectional Study among Hospital Nurses in the Philippines
Authors: Sapar Lester Canarejo , Oducado Ryan Michael F.
Published: August 2021

Background: The global shortage of nurses and the rapid turnover of nurses remain crucial issues and areas of concern that call for immediate attention. Job satisfaction is a recognized determinant of nurses’ decision to stay in their current workplace. However, while nurses’ job satisfaction has received considerable attention among scholars, the results of studies are still mixed.Purpose: The purpose of this study was to revisit and assess the job satisfaction and intention to stay of nurses in two selected hospitals in the Philippines.Methods: A cross-sectional research design was used in this study. A sample of 120 nurses in a public and private hospital in the Philippines responded to the Job Satisfaction Survey and Intent to Stay Scale questionnaires. Descriptive statistics, t-test, one-way ANOVA, and Pearson’s r were employed for data analysis.Results: Results show that the majority (58.3%) of the nurses were neither satisfied nor dissatisfied with their job. Also, nurses intended to neither stay nor quit in their current workplace with only a few (9.2%) had high intention to stay. Nurses were most satisfied in terms of the nature of their job (18.95+2.50) but were dissatisfied with the fringe benefits (12.69+4.11) and operating conditions (12.18+2.58) at work. Nurses in the public hospital (p=0.040) and those with higher salaries (p=0.015) had significantly higher intentions to stay. Job satisfaction and intention to stay were significantly related (p=0.002).Conclusion: Nurses’ job satisfaction is positively linked with their intention to stay in their current workplace. This study highlights that efforts should be made to improve nurses’ job satisfaction to encourage nurses to remain in their current workplace. Also, increasing nurses’ salary particularly those nurses in the private sector is a focal point of consideration to ensure that there is enough supply of nurses in the country.
Host–parasite relationship modulates the effect of African mistletoe leaves on the cholinergic, monoaminergic and carbohydrate hydrolyzing enzymes in fruit fly
Authors: Oyeniran Olubukola H. , Ademiluyi Adedayo O. , Oboh Ganiyu
Published: August 2021

Objectives

Mistletoe infests common plant trees of great medicinal values such as Moringa and Almond. According to folklore, mistletoe leaves have been found to have application as food and medicine in the alleviation of various degenerative diseases. Host–parasite relationship may possibly influence the phytochemical and biological activities of mistletoe leaves. Hence, we examined the polyphenol contents, antioxidant properties, α-amylase, α-glucosidase, acetylcholinesterase (AChE) and monoamine oxidase (MAO) inhibitory activities of African mistletoe leaves obtained from Moringa and Almond host plants in fruit fly in vitro.

Methods

The phenolic constituents of the leaves were evaluated using HPLC system. The antioxidant activities were determined through the ABTS, DPPH and OH free radicals scavenging properties, ferric (Fe3+) and malondialdehyde (MDA) reducing abilities and Fe2+ chelation. The inhibitory effects of the leaves aqueous extracts on α-amylase, α-glucosidase, AChE and MAO activities were also assessed.

Results

The HPLC characterization of the leaves revealed that host plants caused marked variation in their phenolic composition, however, Almond mistletoe leaves had significantly (p<0.05) greater amounts of phenolic constituents. Both Moringa and Almond mistletoe leaves reduced Fe3+ and MDA levels, scavenged free radicals, chelated Fe2+ and inhibited α-amylase, α-glucosidase, AChE and MAO activities with the Almond mistletoe leaves having significantly (p<0.05) higher antioxidant properties and enzyme inhibitory activities.

Conclusions

This present study indicated that host plants could positively modulate the phenolic profile of mistletoe leaves and this probably brought about the vivid noticeable changes in their antioxidant abilities, cholinergic, monoaminergic and carbohydrate hydrolyzing enzymes inhibitory activities.
The potential positive epigenetic effects of various mind-body therapies (MBTs): a narrative review
Authors: Kripalani Simran , Pradhan Basant , Gilrain Kelly L.
Published: August 2021

Mind-body therapies (MBTs), such as mindfulness, meditation, yoga, and tai-chi, are said to improve quality of life by contributing to positive thinking and reducing overall distress. MBTs not only play a role in reducing stress and anxiety, but they are also found to epigenetically affect genes and other areas in our genomes that are implicated in inflammation, stress, and distress. This review analyzes the role of MBTs in reducing the epigenetic changes as reported in five previously conducted controlled studies found in the NCBI PubMed database. The methylation of the tumor necrosis factor gene, implicated in psychological distress, was shown to significantly decrease for the women who performed yoga. For people who took part in mindfulness meditation, there was a significant alteration in a variety of modifications of histone deacetylase enzymes as well as their expression patterns when compared to the control group. Other studies found that long-term meditators had slower biomarkers of aging, known as epigenetic clocks, and methylation in genes associated with immune cell metabolism and inflammation. Different genomic regions known as CpG dinucleotide sites (“CpG islands”) were also found to be epigenetically altered in participants of tai-chi. These controlled studies were promising evidence on the potential of MBTs to affect the epigenetics of an individual. This information will be useful in diagnostic, therapeutic, and preventative measures, and can be an addition to western medicine, in a way that is more holistic and beneficial to the individual.
Molecular spaces and the dimension paradox
Authors: Carbó-Dorca Ramon
Published: August 2021

In this study, the dimension or dimensionality paradox is defined and discussed in a dedicated context. This paradox appears when discrete vector representations of the elements of a molecular set are constructed employing several descriptor parameters, adopting specific values for each molecule. The dimension paradox consists in that when constructing discrete N-dimensional molecular vectors, the primal structure of the attached molecular set, chosen as a collection of different objects, cannot be well-defined if the number of descriptors N and the number of molecules M do not bear a convenient relation like:

N
≥
M

$N\ge M$

. This has implications for the linear independence of the vectors connected with each molecule.

Published: August 2021

During our exploring the anticancer activity of some medicinal plants and their major metabolites, the aerial parts of the EgyptianMatricaria chamomilla(flowers and stems) were studied. GC–MS analysis of the organic soluble extracts of the flowers and stems fractions revealed the presence of 43 and 45 compounds, respectively. Individual chromatographic purification of the flowers and stems’ extracts afforded three major compounds. Structures of these compounds were identified by 1D- and 2D-NMR and HRESI-MS spectroscopic data as bisabolol oxide A (1) and (E)-tonghaosu (2) (as mixture of ratio 2:1) from the flowers extract, meanwhile apigenin-7-β-d-glucoside(3)from the stems fraction. Biologically, the chamomile extracts announced significant antiproliferative activities exceeded in potency by ∼1.5 fold in case of the stem, recording GI5013.16 and 17.04 μg/mL against Caco-2 and MCF-7, respectively. Both fractions were approximately equipotent against the migration of the same cell type down to 10 μg/mL together, compounds1,2but not3, showed considerable growth inhibition of the same cells at GI5013.36 and 11.83 μg/mL, respectively. Interestingly, they were able to suppress Caco-2 colon cancer cells migration at 5.8 μg/mL and potently inactivate the VEGFR2 angiogenic enzyme (1.5-fold relative to sorafenib. The obtained compounds and corresponding chamomile extracts were evaluated against Adeno-7 virus, revealing that both chamomiles’ extracts (flowers and stems) and their corresponding obtained compounds (1–3) were potent in their depletion to the Adeno 7 infectivity titer, however, the flower extract and compounds1–2were more effective than those of the stem extract and its end-product (3).

Published: August 2021

Previous research has shown that delay is a common problem in construction industry.  Weather condition and regulation changes, though being minor factors, are also known as external factors contributing to the delay of project construction. This study involved 118 respondents from the construction industry in Kuantan, Pahang. In order to obtain the data, copies of questionnaire were distributed widely among people in Pahang construction industry. The data were analysed by using Partial Least Squares Structural Equation Modelling version 3. A significant positive relationship between weather conditions and building projects in Pahang construction industry was identified. This study also found a negative relationship between regulation changes and building projects in Pahang construction industry. As expected, weather conditions were found to be one of the factors contributing to delay in the process of projects’ construction in Malaysia. However, weather conditions and the regulation changes did not significantly affect the construction projects in Malaysia. Out of the factors which contributed to delay in building projects, weather conditions, though a minor factor,    played to an extent a part in contributing to extension of the time of the projects in Malaysia. Nevertheless, regulation changes was not considered a vital factor leading to delay in building projects in Malaysia.

Gas Engine Generator (GEG) Power plants as electricity producers need to be maintained using monitoring performance and continuously improvements. Company management of power plant is difficult to make decision for continuous improvement, requires Performance Measurement Tools (PMT) to determine the performance of a GEG power plant. PMT developed using Key Performance Indicator (KPI) that was defined through Forum Group Discussion (FGD) with different field of expertise in company and based on references and the weighting of KPI criterion that was developed by Analytic Hierarchy Process (AHP). This study was a case study at leading medium energy company in Indonesia. PMT is a tool to calculate Performance Score (PS) from the calculation of actual data, contracts and KPI (Power Output/PO, Heat Rate/HR, Operation Ratio/OR, Capacity Factor/CF) weights. If there is a gap in the PS then it can indicate penalty from customer especially PO and HR. Case study was conducted on three power plants that have different capacity and number of engines. The sum of the PS from the KPI will get a Total Performance Score (TPS). The highest TPS value will get a Performance Benchmark (PB) for each power plant.

Published: August 2021

Somatic mutation in the KCNJ5 gene is a common driver of autonomous aldosterone overproduction in aldosterone-producing adenomas (APA). KCNJ5 mutations contribute to a loss of potassium selectivity, and an inward Na+ current could be detected in cells transfected with mutated KCNJ5. Among 223 unilateral primary aldosteronism (uPA) individuals with a KCNJ5 mutation, we identified 6 adenomas with a KCNJ5 p.Gly387Arg (G387R) mutation, previously unreported in uPA patients. The six uPA patients harboring mutant KCNJ5-G387R were older, had a longer hypertensive history, and had milder elevated preoperative plasma aldosterone levels than those APA patients with more frequently detected KCNJ5 mutations. CYP11B2 immunohistochemical staining was only positive in three adenomas, while the other three had co-existing multiple aldosterone-producing micronodules. The bioinformatics analysis predicted that function of the KCNJ5-G387R mutant channel could be pathological. However, the electrophysiological experiment demonstrated that transfected G387R mutant cells did not have an aberrantly stimulated ion current, with lower CYP11B2 synthesis and aldosterone production, when compared to that of the more frequently detected mutant KCNJ5-L168R transfected cells. In conclusion, mutant KCNJ5-G387R is not a functional KCNJ5 mutation in unilateral PA. Compared with other KCNJ5 mutations, the observed mildly elevated aldosterone expression actually hindered the clinical identification of clinical unilateral PA. The KCNJ5-G387R mutation needs to be distinguished from functional KCNJ5 mutations during genomic analysis in APA evaluation because of its functional silence.
Rezidüel Çürük Tespitinde Kullanılan Geleneksel Yöntemin Farklı Yöntemlerle Klinik Olarak Doğrulanması
Authors: SAĞ GÜNGÖR Fatma
Published: August 2021

Amaç: Çürüğün uzaklaştırılmasında kullanılan geleneksel yöntem; yumuşak, enfekte çürük dokuyu sert ve koyu renkli bir dentin yüzeyine ulaşana kadar uzaklaştırmaktır. Rezidüel çürük tespiti için rutinde kullanılan fakat sübjektif bir yöntem olan geleneksel görsel ve dokunsal muayenenin doğruluğu, dental loupe, floresan destekli (Fluorescence Aided Caries Excavation–FACE) bir cihaz ve çürük tespit boyası (CDD) kullanılarak değerlendirilmiştir.
Gereç ve Yöntemler: Restoratif Diş Tedavisi Kliniği’nde rutin çürük tedavisi uygulanmış olan ve kavitede kalan çürüğün geleneksel görsel ve dokunsal muayenenin yanı sıra üç farklı destekleyici yöntem (Dental loupe, FACE ve CDD) ile değerlendirilip verileri kaydedilmiş olan hastalar arasından Sınıf-II (MO–DO–MOD) çürüklü molar dişi bulunan 120 hasta çalışmaya dahil edildi. Dişin çenelerde bulunduğu kadrana ve kavitede kalan çürüğün lokalizasyonuna (Gingival basamak, aksiyal duvar, bukkal duvar, lingual duvar, pulpal duvar, mine-dentin sınırı) göre kaydedilen veriler de değerlendirildi. İstatistiksel analizde Kendall’s W ve Ki-kare testi uygulandı.
Bulgular: Geleneksel görsel ve dokunsal muayene kriterlerine göre çürüksüz olduğu kabul edilen fakat yine de kararsız kalınan 120 kavitenin 61’inin(%50,83) diğer üç yöntemle de çürüksüz olduğu doğrulandı. 35 kavitenin(%29,17) sadece CDD ile boyandığı, 24 kavitenin(%20) hem CDD ile boyandığı hem de FACE cihazı ile çürüklü olduğu tespit edildi. Rezidüel çürüğü tespit etme açısından görsel ve dokunsal muayene ile CDD (p<0,05) arasında istatistiksel bir fark olmasına rağmen, FACE cihazı(p>0,05) ve dental loupe(p>0,05) ile arasında anlamlı bir fark görülmedi. Çürük tespit edilen dişlerin en çok sağ üst kadranda(%37,28) yer aldığı bulundu.
Sonuç: Rezidüel çürük tespitinde kullanılan FACE yönteminin görsel ve dokunsal muayeneyi destekleyici objektif bir yöntem olarak kabul edilebileceği sonucuna varılmıştır.

Gereç ve Yöntemler: İstanbul Okan Üniversitesi Diş Hekimliği Fakültesi Periodontoloji Kliniğine başvuran 380 birey (187 erkek, 193 kadın) çalışmaya dahil edildi. Bireylere sosyodemografik veriler, ağız hijyen alışkanlıklarını değerlendiren anket formu doldurtuldu. Hastaların dental anksiyetelerinin değerlendirilmesinde MDAS testi ve dental anksiyetenin yaşam kalitesine olan etkinin değerlendirilmesinde OHIP-14 testi kullanıldı.

Bulgular: Çalışmaya katılan bireylerin cinsiyetinin, en son diş hekimine gitme zamanının, diş fırçalama alışkanlıklarının ve daha önceki travmatik deneyimlerinin dental anksiyete düzeyi üzerine istatistiksel olarak anlamlı etkide bulunduğu görüldü. Bireylerin MDAS ve OHIP-14 puanları arasında pozitif yönlü istatistiksel olarak anlamlı ilişki tespit edildi. Çalışmaya katılan bireylerin eğitim düzeylerinin, diş fırçalama alışkanlıkları ve düzenli diş hekimine gitme oranları üzerine istatistiksel anlamlı etkisi görüldü.

Sonuç: Çalışmamızda, son bir sene içerisinde diş hekimi ziyaretinde bulunan hastaların dental anksiyetisi daha düşük bulunurken; önceden olumsuz bir dental tedavi geçirmiş olan hastaların dental anksiyete değerleri yüksek bulundu. Dental anksiyetesi düşük olan hastaların düzenli diş fırçalama alışkanlıklarının olduğu görüldü. Dental anksiyetesi yüksek olan hasta grubunda yüksek OHIP-14 skorları alındı.

Pleomorfik adenom, tükürük bezi neoplazmlarının büyük bir kısmını oluşturan ve parotis bezi en sık görülen neoplazmı olup minör tükürük bezlerinde nadiren görülür. Minör tükürük bezi kökenli lezyonlar sıklıkla sert damakta lokalizedir. Yavaş büyüyen ağrısız şişlikle karakterize olup sıklıkla 4.-5. dekatta ve kadınlarda görülür. Etyoloji tam olarak bilinmemekle beraber genetik, çevresel ve mikrobiyal etkenler rol alabilir. Lezyonun boyutu, sınırları ve çevre doku ile ilişkisinde ileri görüntüleme tekniklerinden yararlanılır. Manyetik rezonans görüntüleme (MRG) lezyonun görüntülenmesinde yüksek etkinliğe sahip olsa da kesin teşhis histopatoloji ile konulur. Pleomorfik adenom sağlıklı doku sınırları bırakılarak eksize edildiğinde tedaviye iyi yanıt verir ve nüks nadiren görülür.
Bu olgu sunumunda damakta nadir görülen bir pleomorfik adenom vakasının sunumu amaçlanmıştır.

Background: The aim of this in vitro study was to investigate the effect of different mouthwashes on the color stability of artificial gingiva material that are used in implant retained hybrid prostheses.

Material and Methods: The materials examined in terms of color stability are the gingival colored composite (Gradia Plus Gum, GC Europe,Belgium), pink heat polymerised acrylic resin (Meliodent, Heraeus Kulzer, Germany) and pink feldspathic porcelain (EX-3 Super Porcelain,Noritake,Kuraray, Japan). Forty disc-shaped (10×2 mm) samples were prepared according to the manufacturer's instructions (N=120). Samples of each material were divided into four subgroups (n=10) which immersed in three different mouthwash agents and distilled water (control group) for 14 days, at 37° C. Color parameters were measured with a colorimeter (Konica Minolta CR- 321, Tokyo, Japan) before and after immersion and color differences were calculated according to the CIEDE2000 (ΔE00) formula. The data were statistically analyzed with two-way analysis of variance (ANOVA) and Post Hoc Bonferroni tests (p

This work studies the adsorption of zirconium ions by mesoporous titanium dioxide and by sodium-modified mesoporous titanium dioxide. Experimental maximal adsorption values of zirconium ions by H-TiO2 and Na-TiO2 were found to be 64 mg/g and 109,5 mg/g respectively. This process depends on the interaction time, equilibrium concentration of zirconium ions and acidity of the solution. Adsorption kinetics fit well into the diffusion kinetic model and indicate a several stages of zirconium ions adsorption. Equilibrium adsorption of zirconium ions is well described by the Langmuir's adsorption theory for both adsorbents. The results obtained by inductively coupled plasma mass spectrometry showed that the investigated adsorbent selectively adsorb zirconium ions from the mixture with strontium and yttrium ions in the range of solution pH = 0-1. The percentage of maximum extraction of zirconium ions is 86,61% for H-TiO2 and 94,11% for Na-TiO2. This fact is extremely valuable for nuclear forensics or for the determination of 90Sr in low activity background samples.

Given the considerable success of companies such as Apple, Amazon or Airbnb, the term platform is on everyone’s lips today. Accordingly, platforms have long since also found their way into service science. However, mastering the transition from established product-sales-based offerings to platform-based services and business models comes with a multitude of challenges. In a B2B context, incumbent companies need to carefully evaluate how they can benefit from the establishment of platforms, especially in light of the effects on their existing business models and ties to other actors. Hence, we invited scholars with different backgrounds to provide viewpoints on the opportunities and challenges of the transition to platform-based services and business models in a B2B environment. The individual commentaries provide various insights on how to conduct this transition and benefit from it successfully. To do so, they contrast different approaches for establishing and governing ecosystems around platforms, discuss B2B-specific pitfalls and opportunities of platform business models, uncover the supporting role of platforms for smart service development, and stress the importance of platform and ecosystem thinking as a necessary mindset.

Published: August 2021

In this study, we obtain asymptotic formulas for eigenvalues and eigenfunctions of the one-dimensional Sturm–Liouville equation with one classical-type Dirichlet boundary condition and integral-type nonlocal boundary condition. We investigate solutions of special initial value problem and find asymptotic formulas of arbitrary order. We analyze the characteristic equation of the boundary value problem for eigenvalues and derive asymptotic formulas of arbitrary order. We apply the obtained results to the problem with integral-type nonlocal boundary condition.

As an alternative to means for lowering total cholesterol and low-density lipoprotein (LDL) cholesterol, the paper considers the possibility of using carbon adsorbents. From a medical point of view, the removal of cholesterol with enterosorbents is extremely effective. By binding cholesterol, sorbents reduce the risk of cardiovascular disease. The paper searches for new raw material sources and attempts to create enterosorbents with a high capability to adsorb cholesterol. The aim of the work was to develop adsorbents from spent coffee residue with a large proportion of mesopores, to determine the parameters of the porous structure and to study their adsorption capacity against cholesterol. Samples of activated carbon with a large proportion of mesopores (399 and 465 m2/g) were obtained by the traditional method of carbonization-activation of spent coffee grounds and pre-treated hexane to remove fatty acids. The sorption of cholesterol from alcohol solutions has been studied by spectrophotometric method and its effectiveness for the prevention and treatment of atherosclerosis was proved. It has been shown that a sample of activated carbon from spent coffee residue pre-treated with hexane (maximum value reaches 7.5 mg/g) has the best sorption capacity. The intermediate position is occupied by the sample obtained without pre-treatment with solvent (maximum value reaches 6.3 mg/g). Natural Brand carbon has the weakest sorption characteristics (maximum capacity reaches 5.3 mg/g). It can be stated that the adsorption of cholesterol increases with the growth of the specific surface area of mesopores. The parameters of adsorption processes were calculated using the obtained sorption isotherms. Adsorption isotherms were calculated using the Langmuir and Freundlich equations. It is shown that the values of the maximum adsorption calculated by the Langmuir equation have a good agreement with the experimental data.

Published: August 2021

Microwave irradiation (MWI) in the synthesis of materials has been an actively developing branch of science for the last three decades. Structures based on calcium phosphates (CaP) are one of the most well-known and widely used synthetic biomaterials in orthopedics and dentistry. The main topic of this review is the use of MWI in the formation of biomaterials based on calcium phosphate phases and their complexes with biopolymers (chitosan, alginate, silk fibroin). The physical bases of MW interaction with different materials are considered, including the influence of this irradiation on the structure, physicochemical and mechanical properties of biomaterials (crystallite size, porosity, strength, capability to absorb and release drugs). The main heating mechanisms during MWI are described, namely: the dipolar losses, and losses of conductivity. Important advantages of MWI treatment are reducing processing time, reducing electricity use, reducing waste and improving quality of the synthesized biomaterials. A list and comparison is made of articles describing the production of HA crystals with different morphology (nanowires, spherical, needle- and rod-shaped) with all the initial conditions and their effect on the synthesized material. The latest developments in the field of biomaterials conducted based on the laboratory “Bionanocomposite” of Sumy State University are considered. The original synthesis method of CaP-biopolymer materials is described, as well as the advantages of the synthesized scaffolds over foreign developments. It is expected that this review of the interdisciplinary topic will contribute to the further study of other new applications of microwave technologies in the synthesis of the latest modern biomaterials created by scientists, biomedical engineers in other laboratories and institutions in Ukraine and around the world.
