Published: July 2020

the design, construction and operation of high-rise earth dams in seismic regions, such as the territory of the Republic of Uzbekistan, requires constant improvement of the methods to calculate them under various loads, both of a static nature (gravitational forces, hydrostatic, etc.), and of a dynamic nature, including seismic effects. Emergency situations at such facilities or their partial destruction under any impact can lead to disastrous aftermath. The aim of this study is to develop a mathematical statement and an algorithm for numerical solution to an unsteady-state problem for an earth dam in a plane elastic statement. To verify the proposed methodology and the corresponding complex of applied programs, a solution to the test problem was given (the Lamb’s problem). According to the developed methodology and algorithm based on numeri-cal method of finite differences, the problem of studying the stress-strain state was solved under shear stress on the foundation (in the form of a seismogram) on the example of the high-rise Charvak earth dam located near Tashkent city. The solution is presented in the form of distribution lines of equal displacements, stress-es along the dam body, depending on time. The most vulnerable zones of the earth dam under consideration were identified.

Los arabinoxilanos ferulados son los principales polisacáridos no amiláceos de los granos de cereales, que se localizan en las paredes celulares del endospermo, en la capa aleurona y en el pericarpio de los mismos. Estos polisacáridos se han reportado en los cereales más importantes, como trigo (Triticum aestivum L.), centeno (Secale cereale L. M. Bieb.), cebada (Hordeum vulgare L.), avena (A. sativa), arroz (Oryza sativa L.), sorgo (Sorghum vulgare), maíz (Zea mays L.) y mijo (Panicum miliaceum L.). Recientemente se han realizado esfuerzos enfocados a la extracción de arabinoxilanos ferulados a partir de subproductos de la industria procesadora de cereales, como de los pericarpios de maíz y de trigo, así como del “nejayote” que es el agua residual de la nixtamalización del maíz. Los arabinoxilanos ferulados forman soluciones viscosas y pueden formar geles bajo la acción de ciertos agentes oxidantes. Además, presentan características físico-químicas determinantes para su capacidad gelificante. Los geles de arabinoxilanos han despertado un gran interés debido a que presentan características interesantes como: olor y sabor neutro; estabilidad al pH, a los cambios de temperatura y de concentración de electrolitos; así como una estructura macroporosa. Estas características les confieren aplicación potencial como matrices para la liberación controlada de biomoléculas en aplicaciones alimentarias y no alimentarias, lo cual podría dar valor agregado a los cereales o subproductos de cereales de los cuales pueden ser extraídos estos polisacáridos. Esta revisión incluye los reportes más recientes sobre las características fisicoquímicas y la capacidad gelificante de arabinoxilanos ferulados, tema sobre el cual ha resurgido el interés en los últimos diez años. La generación de nuevo conocimiento sobre este polisacárido y sus geles podría sentar las bases para su aplicación en distintas áreas como la agroalimentaria, la biomédica y la cosmética, entre otras.

México es un país con gran diversificación de poblaciones silvestres de tomate (Solanum lycopersicum L.), pero poco estudiadas, por lo que se requiere explorar y conocer su potencial genético como fuente para mejorar la productividad, tolerancia a sequía, salinidad y resolver problemas fitosanitarios. Con el objetivo de determinar la variabilidad genética en 120 familias de tomate derivadas de una población nativa del Estado de Puebla, con base en características de interés agronómico, se sembraron y caracterizaron en un invernadero cubierto de malla antiáfidos a los 60 d después del trasplante. Los análisis de varianza detectaron diferencias (P ≤ 0.05) en las seis variables evaluadas, y el análisis de componentes principales mostró que dos variables (calificación general y diámetro de tallo) describieron 59.7 % de la variabilidad morfológica. La representación gráfica de los dos principales componentes permitió identificar a seis grupos de familias, distribuidas en los cuatro cuadrantes. Los Grupos I y VI concentraron a las familias sobresalientes en diámetro de tallo, altura de planta, número de racimos con fruto, con plantas sanas y uniformes. El Grupo II aglutinó 84 % del total de las familias buenas; y los Grupos III y IV se caracterizaron por integrar familias de regulares a malas.

En el estado de Tabasco, México se pueden encontrar plantas de chile (Capsicum spp.) de forma silvestre que se diferencian por sus características morfológicas. Con el objetivo de recolectar y evaluar in situ la diversidad morfológica de chiles silvestres, de enero a septiembre de 2013 se realizó la exploración de 48 comunidades en 14 municipios del estado de Tabasco. Durante la exploración se recolectaron y tomaron datos de variables de planta, flor y fruto de 89 colectas. Se encontró la presencia de las especies C. annuum var. glabriusculum en los morfotipos ‘Amashito’, ‘Ojo de cangrejo’ y ‘Garbanzo’; y C. frutescens L. en el morfotipo ‘Pico paloma’. El análisis de componentes principales y de conglomerados con las 12 variables relevantes, diferenciaron a las colectas en dos grupos, los cuales se formaron con base en variables de fruto y de hoja. El primer grupo se formó con las 43 colectas de C. annuum var. glabriusculum que se caracterizan por tener frutos de forma redonda, corola pequeña de color blanco y una flor por nudo; el segundo grupo se formó con 46 colectas de C. frutescens L. que se caracterizan por tener frutos alargados, corola de color blanca verdosa y de dos a tres flores por nudo. Al interior de los grupos también se presentó una diferencia gradual y continua de las variables, lo que permitió formar subgrupos. En los chiles silvestres del Estado de Tabasco se encuentra diversidad morfológica, recurso genético valioso que debe conservarse.

Authors: Low Hui Min  , Lee Lay Wah
Published: July 2020

Since the implementation of 'Educational Blueprint 2013-2025' and 'Zero Reject Policy' in Malaysia, there are increasingly efforts from the Malaysian Ministry of Education to include students with Autism Spectrum Disorder(ASD) into regular mainstream education. A case study investigation was conducted with a mother with two children with different severity levels of ASD. In a semi-structured interview, the mother described her experiences and aspirations of education arrangements for both her children. Through the eyes of a mother, we find a strong belief that children with ASD could learn like others when given adequate opportunities and learning aids. This unique case study offers an archetypical representation of issues and challenges faced by parents of children with ASD in Malaysia, in advocating for inclusive education for their children.

Published: July 2020

The study of ethical leadership involving corporate leaders has gained importance in recent years. This research investigated the link between ethical leadership and performance using data from the medical center in Taiwan. Drawing on person–environment fit theory, we examined the mediating roles of person– group fit and person–job fit in the relationship between ethical leadership and work engagement. A convenience sampling was used to collect 447 valid questionnaires, and structural equation modeling was used for analysis and testing. Results revealed that ethical leadership is positively related to work engagement. Further, P–G fit and P–J fit mediate the relationship between ethical leadership and work engagement. Finally, implications for theory and practice are discussed
The New "Chain" of Title
Authors: Koronczok Matt
Published: July 2020

Blockchain has recently driven a financial revolution in the realm of virtual currencies, smart contracts, and escrow services. Over the last year, the technology has also been mentioned as a harbinger of change in real estate transactions and land title research. Speculation about the technology’s likely impact in various industries is more warranted in some instances than others. Goldman Sachs, for its part, has suggested that, like other industries which have benefitted from the transparency and efficiency of blockchain technology, the title insurance industry will experience a dramatic boost in the near future. This suggestion, however, fails to recognize both the efficiency already achieved by industry title plants and the extent of legal problems that arise during title research—very few of which blockchain holds promise of mitigating.

Public land titling offices, on the other hand, stand to gain significantly by adopting the technology. Because of blockchain’s decentralized and unalterable structure, the technology is useful for protecting records from natural disasters and government corruption. This Comment charts the real property legal issues that blockchain likely will and will not address. Developers and investors will find that understanding what blockchain can and cannot do for the real estate industry is crucial, because blockchain hype looms large and, as Bitcoin’s recently fluctuating prices prove, the way forward for blockchain investment can be uncertain.

Helvine-group minerals from Norwegian granitic pegmatites and some other granitic rocks: Cases of significant Sc and Sn contents
Authors: Raade Gunnar
Published: July 2020

Helvine-group minerals from two granitic pegmatites have disparate compositions, from nearly pure helvine (Ågskardet, northern Norway; Devonian) to helvine close to ternary compositions (Heftetjern, southern Norway; Precambrian). Metagranite from Høgtuva (northern Norway; Precambrian with Caledonian metamorphic overprint) contains Zn-rich danalite. The Ågskardet helvine contains up to 0.46 wt.% SnO2, and the Heftetjern ternary helvine shows a maximum of 1.74 wt.% Sc2O3. Helvine minerals were also analyzed from three occurrences connected to peralkaline granite (ekerite) of the Permian Oslo Rift. Nearly pure genthelvite (99.19 mol.%) occurs in miarolitic cavities at Gjerdingselva. Two mineralogically different granitic pegmatites derived from the same ekerite pluton in the southern part of the Oslo Rift show quite distinct helvine compositions, from nearly continuous solid solution between helvine and genthelvite in crystals with oscillatory zonation (Rundemyr) to solid solutions midway between danalite and genthelvite (Bakstevalåsen). The Rundemyr crystals have a maximum SnO2 content of 1.28 wt.%. The incorporation of minor elements (Ca, Mg, Al, Sn, Sc) in helvine-group minerals is discussed with emphasis on their chalcophilicity characteristics. For stereochemical reasons, Sn in helvine minerals must be tetravalent, even if Sn2+ is more chalcophile than Sn4+.
Gas-sensing features of nanostructured tellurium thin films
Authors: Tsiulyanu Dumitru
Published: July 2020

Nanocrystalline and amorphous nanostructured tellurium (Te) thin films were grown and their gas-sensing properties were investigated at different operating temperatures with respect to scanning electron microscopy and X-ray diffraction analyses. It was shown that both types of films interacted with nitrogen dioxide, which resulted in a decrease of electrical conductivity. The gas sensitivity, as well as the response and recovery times, differed between these two nanostructured films. It is worth mentioning that these properties also depend on the operating temperature and the applied gas concentration on the films. An increase in the operating temperature decreased not only the response and recovery times but also the gas sensitivity of the nanocrystalline films. This shortcoming could be solved by using the amorphous nanostructured Te films which, even at 22 °C, exhibited higher gas sensitivity and shorter response and recovery times by more than one order of magnitude in comparison to the nanocrystalline Te films. These results were interpreted in terms of an increase in disorder (amorphization), leading to an increase in the surface chemical activity of chalcogenides, as well as an increase in the active surface area due to substrate porosity.

Published: July 2020

Antithrombotic therapy and Fibrinolytics are central to the management of Acute Coronary Syndrome. These are high alert medications that are prone to adverse effects thus requiring strict monitoring. Effective usage of these medications results in reduction of recurrent ischaemic events including MI and stent thrombosis. Reducing the ischemic events and maintaining a balance between normal physiological coagulability and the bleeding is vital to avoid bleeding complications during the therapy. This therapy induced adverse effects increases mortality and morbidity rate. In our study we are mainly focussing on, comparing and demonstrating the effectiveness of enoxaparin over heparin and Tenecteplase over streptokinase and to assess, evaluate and management of adverse events by Narinjo assessment scale. Majority of adverse events were seen in subjects with social history of alcoholism, this shows alcoholism decreasing the threshold to adverse events. Causality assessment of adverse effects were 17.45% Possible and 91.6% were probable. The streptokinase was found superior than tenecteplase and enoxaparin was found superior than heparin in terms of adverse events and hospitalisation period. ACS is an drastic health disorder that increases the morbidity rate, mortality rate, economic burden and well being of the persons. Thus individualisation of drug regimen and strategies for early detection, monitoring and management of adverse events is mandatory.
Structural Use of Expanded Polystyrene Concrete
Authors: ADEALA Adeniran Jolaade , SOYEM Olugbenga Babajide
Published: July 2020

Expanded polystyrene (EPS) wastes are generated from industries and post-consumer products. They are non-biodegradable but are usually disposed by burning or landfilling leading to environmental pollution. The possibility of using EPS as partial replacement for fine aggregates in concrete has generated research interests in recent times. However, since the physical and mechanical properties of EPS are not like those of conventional fine aggregates, this study is focussed on the use of EPS as an additive in concrete while keeping other composition (sand and granite) constant. Expanded polystyrene was milled, the bulk density of EPS was 10.57kg/m3 and particle size distributions were determined. Engineering properties of expanded polystyrene concrete were determined in accordance with BS 8110-2:1985. The result showed that the amount of expanded polystyrene incorporated in concrete influence the properties of hardened and fresh concrete. The compressive strengths of 17.07MPa with 5 % expanded polystyrene concrete at 28 days for example can be used as a lightweight concrete for partitioning in offices. Incorporating expanded polystyrene granules in a concrete matrix can produce lightweight polystyrene aggregate concrete of various densities, compressive strengths, flexural strengths and tensile strengths. In conclusion, this reduces environmental pollution, reduction in valuable landfill space and also for sustainability in construction companies
Examination of Systole/Diastole Ratio of Umbilical Artery in the third Trimester Gestational Pregnancy and its Correlation with Lactate Acid Level in Fetal Cord
Authors: Lumbanraja Sarma Nursani , Yasnil Muhammad Rizki , Siahaan Andre Marolop Pangihutan
Published: July 2020

BACKGROUND: Fetal distress is a serious complication of perinatal infants and refers to fetal hypoxia in the uterus and asphyxia immediately after the baby is born. The occurrence of uteroplacental disorders is related to various factors, including maternal and fetal factors. When fetal distress occurs, umbilical cord blood flow and fetal blood flow decrease, which in turn causes fetal circulation and respiratory dysfunction in the womb. Evaluating cord blood flow characteristics with ultrasound can provide a reference for prediction and diagnosis of fetal distress, especially by conducting an ultrasound examination of the Doppler S/D ratio of the umbilical arteries especially at gestational age >30 weeks.
OBJECTIVE: The objective of the study was to assess the correlation between umbilical artery SD ratio examinations with lactate acid levels in the umbilical
METHODS: This study was an observational analytic study with a cross-sectional study design. The research was conducted in Haji Adam Malik General Hospital Medan and Satellite Hospital. The sample was pregnant women who meet the inclusion and exclusion criteria, we found 38 of pregnant women from January to December 2019.
Results: The average age of patients in this study was 30 (5) years, the majority of multiparous patients were 25 (47.2), the average gestational age was 38 (2) weeks. Most births in this study were SC 38 (71.7) with an average S/D ratio in the study of 2.81 (0.52) and a mean lactic acid level of 2.7 (0.4). The average Apgar score in this study was 8/9 as many as 29 (54.7), the average S/D ratio is obtained with the average Apgar score of the patient. From this study, it is known that the higher the Apgar score, the higher the average S/D ratio value in patients. The mean patients with poor Apgar outcomes (5/6) have an S/D ratio of 2.5. From the analysis using ANNOVA also obtained p < 0.28. This shows that there is no significant relationship between Apgar score and S/D ratio. Increasing in lactic acid was found in infant outcomes with an Apgar score of 9/10 with a mean value of 2.9 (0.5). From the ANNOVA analysis, a p = 0.99 was also found. This showed that there was no significant relationship between the levels of lactic acid and Apgar score for infants. Lactic acid has a very weak positive correlation with Apgar score for infants with an R value of 0.274 (p = 0.047), this shows that lactic acid does not have a strong relationship with infant outcomes.
CONCLUSION: There was no correlation between umbilical cord S/D ratio and lactic acid with Apgar score. Lactic acid has a very weak positive correlation with the infant Apgar score with an R value of 0.274.
La naissance de la pulsion de mort
Authors: Rozmarin Eyal , Signorelli Mila
Published: July 2020

L’objectif de l’article est d'argumenter que l’association entre pulsion de mort, violence et autodestruction peut être trompeuse et artificielle. Cette association est le camouflage symptomatique de quelque chose de complètement différent, à savoir la psychologisation qui rend inconscient l'impact des forces sociales. Les forces sociales, lorsque incorporées au sein de la famille et dans notre constitution en tant que sujets, nous font penser qu’il est naturel et souhaitable de vouloir tuer et mourir. Mais une telle représentation pourrait être vue comme une construction ou l’invention d’un père abandonnique.

Application of Artificial Intelligence in Modern Art Teaching
Authors: Kong Fanwen
Published: July 2020

Despite its rapid development, the artificial intelligence (AI) has not been deeply applied in art teaching. Hence, this paper attempts to design strategies for applying AI in art teaching. For this purpose, the authors reviewed the current application status of AI in art teaching and summed up the problems with these applications. Next, the promotive role of AI in art teaching was analyzed in detail, and three strategies were developed to promote AI applications in modern art teaching, namely: expand the adaptability of AI-based art teaching; improve the intelligent teaching mode of art teaching; and enhance the artistic experience and atmosphere of AI-based art teaching. At the same time, to evaluate the application effect of AI in art teaching, a performance analysis model was designed based on analytical hierarchy process (AHP) and grey clustering. The proposed model can quantify the application effect of AI in art teaching, and it has a good application potential.

Preventative screening of at-risk population is a crucial step in the early detection of dementia. Building alternative and ecologically validated screening tests are challenging. This pilot project attempts a) to assess the effectiveness of a culturally oriented computerized screening test for major neurocognitive disorder (eHAST) b) to compare it with the Greek version of the UCSF Brain Health Assessment (BHA) which is culturally neutral. Our study focused in a) evaluation of eHAST’s discriminant ability between groups of older adults with cognitive concerns (OACC) (n=35) vs older adults with Mild Cognitive Impairment (MCI) (n=114) and dementia (n=67), and MCI vs dementia in a sample of 216 cases. b) comparison of eHAST’s discriminant ability vs BHA’s in 116 subjects.   The absence of normative data for both of the tests led to balance the sample regarding age and educational level for the comparisons between groups of OACC vs MCI (n = 56) and MCI vs dementia cases (n = 60). All participants were neuropsychologically assessed, clinically diagnosed. Results showed a) Reliability check (Cronbach's alpha) of eHAST was 0.9 and discriminant analyses in separating groups of OACC vs MCI displayed a correct classification rate of 77.3%, for MCI vs dementia 80.6% and OACC vs dementia 89.1% (cross-validated). b) In OACC vs MCI comparison, BHA’s discriminant ability was 67.3% and eHAST’s was 60.7%. In MCI vs dementia comparison, BHA’s discriminant ability was 77.2% and eHAST’s was 76.7% (cross-validated). These preliminary results of the implementation of eHAST are encouraging as the test presents sufficient discriminant ability between groups of OACC-MCI, MCI-Dementia & OACC- Dementia. Also, performs similar scores to BHA, which is a state-of-the-art screening test. The use of a tablet pc in the assessment of cognitive disorders in the elderly can have a catalytic role in the detection of dementia.

Authors: Liu Guang Fu
Published: July 2020

This topic is based on the research and development of inorganic silver-loaded antibacterial materials with good antibacterial activity, and the preparation of silver-loaded calcium carbonate inorganic nano-antibacterial agents by redox reaction. At the same time, the mixed rare earth oxide was added to the ceramic glaze containing silver nano antibacterial agent, and the nano antibacterial building sanitary ceramics were prepared by firing at 1180 °C in an oxidizing atmosphere. This experiment investigated the effect of adding mixed rare earth oxides on the quality and properties of glaze. Experiments show that the new glaze has stronger antibacterial effect than the nano antibacterial glaze without mixed rare earth oxide, and the glaze quality is good. After adding 0.5 wt% of mixed rare earth oxide, the whiteness, abrasion resistance, hardness and thermal shock resistance of the glaze were significantly improved.This topic is based on the research and development of inorganic silver-loaded antibacterial materials with good antibacterial activity, and the preparation of silver-loaded calcium carbonate inorganic nano-antibacterial agents by redox reaction.

Published: July 2020

The micro-mechanical properties and micro-structural characteristics of the interfacial transition zones of recycled concrete with graphene oxide were studied by using nanoindentor. The results showed that the average elastic modulus and width of the interfacial transition zone of recycled concrete with graphene oxide between new paste matrix and natural aggregate were about 20GPa and 30-35μm, respectively; The mean elastic modulus and transition zone width of the interfacial transition zone between new paste matrix and old paste matrix was about 35GPa and 25-30μm, respectively. By analyzing and calculating the probability distribution of hydration products, it was found that the graphene oxide template increased the proportion of calcium silicate hydrate in the hydrate and enhanced the content of calcium hydroxide crystal group. Compared with ordinary recycled concrete, the elastic modulus distribution in the interfacial transition zone was more uniform and the microstructure was more stable. It can be concluded that graphene oxide can enhance the mechanical properties and microstructure of the interfacial transition zone of recycled concrete so as to improve the macroscopic mechanical properties of recycled concrete.

Published: July 2020

To investigate the effects of carboplatin (CBP) injection on apoptosis induction in the human lymphoma cell line Raji and to explore the underlying mechanism, Raji cells were randomly divided into two treatment groups. Cells in the experimental groups were treated with 15 μM CBP injection, those in the control groups were treated with solvent, and both groups were treated for 24, 48 and 72 h. Cells from each group were collected for subsequent assays. For each group, the relative expression of B-cell lymphoma-2 (Bcl-2) was determined by Western blot (WB), the expression pattern of Bcl-2 was observed by immunocytochemistry (ICC), and cell apoptosis was observed after Hoechst 33342 staining. Real-time PCR detection of the relative expression levels of the Bax and caspase-3 genes in each group of cells were performed. The WB results showed that the relative expression of the Bcl-2 protein significantly decreased 48 and 72 h after treatment in the CBP groups compared with the control groups (P<0.001), and a significant decrease in the expression of this protein was also noted at 48 h vs 24 h, 72 h vs 48 h, and 72 h vs 24 h with extremely significant differences (P<0.001). Moreover, the expression of the Bcl-2 protein decreased as the duration of CBP treatment increased, showing a time-dependent manner. The ICC results were consistent with the WB findings. The expression of the Bcl-2 protein in the CBP treatment group was significantly reduced 48 h and 72 h after treatment compared with the control group (P<0.001). A time-dependent manner was also noted in the expression of this protein, i.e., the expression level decreased gradually at 24, 48, and 72 h after treatment with statistically significant differences (P<0.001). Hoechst 33342 staining showed that the apoptosis rates at the three time points in the treatment groups were significantly higher than those in the control groups (P<0.001), and a time-effect relationship was observed. The apoptosis rate increased over time with a significant difference (P<0.05). The PCR results showed that the Bax and caspase-3 gene expression trend was the same but opposite that of Bcl-2. After treatment for 24 h and 48 h, the gene expression of the medication groups decreased with a very significant difference (P<0.001), and with prolonged action time, the relative expression of the genes in the medication groups showed an upward trend. Comparing 48 h with 72 h and 24 h with 72 h, the gene expression levels also increased, reaching a very significant difference (P<0.001), and there was a certain time dependence. CBP injection significantly reduced the expression of the Bcl-2 protein and induced apoptosis of Raji cells in a time-dependent manner. Moreover, CBP injection can increase the expression levels of the Bax and caspase-3 genes.

Parkinson’s disease (PD) has the second highest prevalence among neurodege - nerative diseases. In Colombia, PD population dynamics are currently unknown. Health records offer a unique resource to study frequency and multi-morbidity of chronic diseases. The aim of this research is to estimate prevalence and staging using administrative data (AD) provided by Health Maintenance Organizations (HMOs). A cross-sectional study was conducted using 2015 AD from two Colombian HMOs (4.312.928 beneficiaries, 9.01% of the affiliated Colombian population). PD prevalence and severity was estimated by age and sex. Prevalence was adjusted to WHO demographics. Age-adjusted PD prevalence was 205.89 per 100.000 inhabitants. Prevalence increment of 62.13% was found between those aged ≥40 years and those aged ≥50 years. Similarly, each extra decade (50-80+) represented an increment of 83.65%, 80.95%, and 35.10%. Between 40 and 89 years, males exhibited a significantly higher PD prevalence compared to females. Advanced PD was more frequent as age increased from 3.77% in the group between 40 to 49 years to 25.86% in those older than 89 years. More common related comorbidities were arterial hypertension, diabetes, and psychiatric disorders; the first two increased their frequency with age, and the last one maintained its prevalence across all age groups. AD sets are useful to estimate the prevalence and staging of PD. Prevalence of PD in Colombia is higher in men and increases with age, as well as disease severity.
