Curcumin attenuates butter fat induced hyperlipidemia in mice
Authors: Sarker Siddhartha , Haque Md. Iqramul , Sujan Khaled Mahmud , Talukder Maha Islam , Miah Mohammad Alam
Published: June 2019

Long-term intake of high-fat food disrupts lipid metabolism, resulting in fat accumulation, obesity, and hyperlipidemia. Curcumin, active ingredients of turmeric plants, has been shown to possess potent antioxidant and hypolipidemic properties. The study was conducted to observe the effects of curcumin on butter induced hyperlipidemia, hematological values and physio-pathological alterations in liver and aorta in mice. A total of 40 Swiss Albino mice (Mus musculus), aged 28-30 days with an average body weight of 27g were randomly divided into 2 groups. Group A was considered as non-treated control (NT) (n=8) and fed on standard mice pellet and fresh drinking water. Another group was considered as butter group (n=32), fed on standard mice pellet enriched with 10% butter and after 5 weeks, mice of butter group were subdivided into 4 equal groups (n=8). Group B was considered as butter treated (BT) group fed on standard mice pellet enriched with 10% butter. Group C (C1%), group D (C2%) and group E (C3%) fed on standard mice pellet enriched with 10% butter plus curcumin 1%, 2% and 3% in drinking water respectively. The experiment was carried out for period of another 10 weeks. Body weight gain of all mice was gradually increased and maximum weight gain was recorded in mice of butter fed group. Supplementation of curcumin to butter treated mice (group C, D and E) prevented weight gain. Mice treated with butter fat had significantly (p<0.01) higher hemoglobin (Hb) concentration, total erythrocyte count (TEC) and packed cell volume (PCV). Treatment with curcumin of 1%, 2%, and 3% concentration on butter supplemented mice didn’t alter or rather enhanced the hematological values. In case of lipid profile, supplementation of butter fat in feed significantly increased the total cholesterol, triglycerides and LDL cholesterol. However, addition of curcumin extracts of 1%, 2% and 3% concentration to the butter fed group mice dramatically reduced  the total cholesterol and LDL-cholesterol values and more prominent result was observed in 2 % curcumin treated mice. Histo-pathological studies of liver and aorta revealed that addition of 10% butter to feed induced a few fatty changes along with pyknotic nuceli in the hepatocytes, thickened wall of aorta with disorganized lining cells. Again upon curcumin treatment, no such changes were detected in the liver and aortic tissues of group C, group D and group E. Our study revealed that the butter fats have harmful effects on weight gain, on lipid profile and on organ structures without deteriorating normal hematological values. However, these harmful effects could be mitigated by addition of curcumin extracts.

Difference in the patterns of food consumption of rural households in Bangladesh
Authors: Hossain Mahbub
Published: June 2019

Food consumption pattern hints the proportion of various foods that households consume to meet their nutritional requirements, which is crucial to know from the policy perspective. While several studies have documented a strong link between household dietary diversity and nutritional status of household members, especially of children; the evidence that whether or not the proportions of households’ intake of nutrients from different foods differ across the income levels is almost nonexistent. The present study fills in this void in the literature by generating evidence on variations in the consumption pattern with income in the context of a low middle-income country. By using data from a national level rural households survey, this paper finds that food consumption pattern significantly differs across income classes and notably with a rise in income households tend to substitute less nutritious food with more nutritious food. However it is found that carbohydrates dominate the rural households’ diets with few proteins, vitamins, and minerals. Hence as far as food security is concerned, policymakers need to emphasize on policies that would promote households’ behavioral change in respect of food choices. Less income inequality in the economy may also be conducive to improve national food security.

Native language and school. An anthropological view
Authors: Martynova Marina Yu.
Published: June 2019

There are many levers both to construct social differences and to eliminate them. In my opinion, one of the most effective tools to socially construct identities is educational policy. People belong to certain cultural traditions primarily due to upbringing and socialization. Education, especially school education, plays a significant role in the educational process. The article describes various issues of school education in ethnic languages and the problem of preservation of these languages in the regions of Russia.
To what extent is language a historically given phenomenon and to what extent is it a construct, the result of “social engineering” and ideological work? Language is not just a tool of communication in a social group, but it also provides a feeling of uniqueness among other nations and states. National and ethnic identity should be viewed in close connection with language. Now, when the multiculturalality of society is growing all over the world, the problem of preserving the ethnocultural identity of a population, passing the traditions of fathers and grandfathers to the younger generation is becoming increasingly urgent. While preparing young people for life in a multilingual and multicultural society, it is important to find a balance between the ethnic and cultural needs of a citizen on the one hand and the tasks of consolidating the population in the interests of a single state  – on the other.

Authors: Kolomiets Oksana P.
Published: June 2019

The article discusses the forms of business activities that have been common among the indigenous people of Chukotka since the beginning of the 2000s. It is important to study how the opportunities for the development of small business and self-employment are realized in practice. Currently 993 legal entities are registered in the district, 68 of them are tribal or territorially-neighboring communities of the indigenous peoples of Chukotka, 29 of them are peasant farms; of 1162 individual entrepreneurs 100 are entrepreneurs from among the indigenous people of Chukotka. The area of business in which indigenous people who live in both rural areas and Chukotka cities can be realized is micro-enterprises. On the territory of the region there are special state and private programs to support small business, but the difficulties for Chukchi businessmen do not become less. The main problems identified are the high cost of delivering goods (for rural entrepreneurs airline fares are unbearable), high utility rates, the lack of stable sales markets for goods and services produced, the low level of economic knowledge required for conducting financial and economic activities and reporting to government bodies.
At the same time further development of the region is not possible without the development of a private initiative in the field of traditional environmental management, without the mandatory use of new waste-free technologies for the processing of reindeer products, marine hunting, fishing, hunting, for the so-called «community» business; production of souvenirs of leather, bone walrus, whales, deer horns; tailoring and repair of fur products; development of modern ethno-design; transportation services; daytime employment services for children; construction and repair work; personal services; catering; tourist services.
This article is intended to attract scientific and public interest to this issue.

Assigning Weights for Modified Project Quarter Back Rating Based Construction Project Performance Model
Authors: Ingle Prachi Vinod , Mahesh Gangadhar
Published: June 2019

The Indian construction industry is facing challenges due to performance shortfalls. The construction projects are highly complex, distinctive, fragmented and do not have of well-established performance assessment models to evaluate their project success. Assessing overall project success is not possible to measure by single factor. To address this limitation, the Modified Project Quarter Back Rating (PQR) model was developed for the Indian construction industry. Modified PQR model’s output is a project score based on performance areas affecting project success and outcome. The model integrates ten performance areas that have identified through literature review. Performance areas included in the model are; (i) Cost (ii) Schedule (iii) Stakeholder satisfaction (iv) Safety (v) Quality (vi) Finance (vii) Environment (viii) Communication and collaboration (ix) Customer relation and (x) Productivity. These performance areas are measured through different performance metrics; i.e. performance metrics scores are aggregated to compute performance area scores. The model gives a single score that will help in comparing overall performance for different projects. This paper attempted to highlight the importance of performance metrics in modified Project Quarter Back Rating (PQR) based construction project performance assessment model for the Indian construction industry. The validity of the model needs assigning appropriate weights to the performance metrics as the weightage determines the relevance. Appropriate weights were determined using two round Delphi survey with 12 experts. Findings reveal that two performance metrics; return business from customer relation and OSHA recordable from safety have high weights. This modified PQR model will help key participants of the industry to compare the performance of various projects and to monitor performance areas that impact project performance rating.

Authors: Tamsir Mohammad , Dhiman Neeraj
Published: June 2019

This work concerns for solving of coupled Burgers’ equations (CBEs) in 2D and 3D via DQM based on cubic trigonometric B-spline (CTB) shape functions. In the method, the shape functions are modified and used for the integration of space derivative. Consequently, the CBEs are transformed into the integral equations. These integral equations are solved by an “optimal strong stability-preserving Runge-Kutta method (SSP-RK54)”. Three examples are taken for analysis. The assessment of the present results are done with a number of already presented results in the literature. We initiated that the present method generates more precise results. Straightforward algorithm, little amount of computational cost and less error norms are the major achievements of the method. Therefore, the present method possibly will be very valuable optional method for the computation of nonlinear PDEs. Moreover, the analysis of method’s stability is also done.

Authors: Zhu Zhipeng , Wang Guangyu , Dong Jianwen
Published: July 2019

Land use changes have significantly altered the natural environment in which humans live. In urban areas, diminishing air quality poses a large threat to human health. In order to investigate the relationship between land use/cover change (LUCC) and air pollutants of Wuyishan City between 2014–2017, an integrated approach was used by combining remote sensing techniques with a landscape ecology methods. Annual, seasonal, and weekly mean values of air pollutant (SO2, NO2, CO, PM10, O3, PM2.5, black carbon) concentration and atmospheric visibility were calculated to develop a Pearson correlation between LUCC and air pollutants concentration. Results showed an increase in forested areas (1.79%) and water areas (15.89%), with a simultaneous reduction in cultivated land (6.47%), bare land (72.61%), and built-up land (16.03%) from 2014 to 2017. The transition matrix of land use types revealed that (i) forest expansion took place mainly at the expense of cultivated land (13.94%) and bare land (27.48%); and (ii) water area expansion took place mainly at the expense of cultivated land (1.29%) and forests (0.21%). In 2017, the proportion of days with AQI level I (94.52%) was higher than that in 2014 (88.77%). Additionally, the annual average visibility in 2017 (37.42 km) was higher than 2014 (27.46 km). The concentration of SO2, CO, O3, and black carbon was positively correlated with the cultivated land. The concentration of SO2, CO, and black carbon negatively correlated with the increase of forests. PM10, and PM2.5 is negatively correlated with the water area. Visibility was found to be positively correlated with forested area, and negatively correlated with cultivated land. The findings from this study represent a valuable gain in understanding of policies aimed at improving, safeguarding, and monitoring air quality. These results can be used to inform land-use planning decisions in a comprehensive way and could be a valuable tool for LUCC rational management strategies.
Transmission of Collective Memory and Jewish Identity in Post-War Jewish Generations through War Souvenirs
Authors: Bronec Jakub
Published: July 2019

The article includes a sample of testimonies and the results of sociological research on the life stories of Jews born in the aftermath of World War II in two countries, Czechoslovakia and Luxembourg. At that time, Czechoslovak Jews were living through the era of de-Stalinization and their narratives offer new insights into this segment of Jewish post-war history that differ from those of Jews living in liberal, democratic European states. The interviews explore how personal documents, photos, letters and souvenirs can help maintain personal memories in Jewish families and show how this varies from one generation to the next. My paper illustrates the importance of these small artifacts for the transmission of Jewish collective memory in post-war Jewish generations. The case study aims to answer the following research questions: What is the relationship between the Jewish post-war generation and its heirlooms? Who is in charge of maintaining Jewish family heirlooms within the family? Are there any intergenerational differences when it comes to keeping and maintaining family history? The study also aims to find out whether the political regime influences how Jewish objects are kept by Jewish families.
Using Different Ways of 3D Reconstruction of Historical Cities for Gaming Purposes: The Case Study of Nafplio
Authors: Kargas Antonios , Loumos Georgios , Varoutas Dimitrios
Published: July 2019

Virtual reality (VR) technologies offer a unique opportunity in “3D reconstruction” of cultural monuments and historical cities that do not longer exist or have been modified (partially or totally). Even though technological capabilities are growing fast, emphasis is mainly given on developing virtual museums and exhibitions, while archaeological places and excavations are following. The present paper presents two distinct approaches for 3D reconstruction of the historical city of Nafplio (Greece), by developing 3D models for buildings and monuments the way they used to be in the 19th century. The authors have used their professional and academic experience deriving from their participation in a European Commission co-funded project in the framework of the Partnership Agreement 2007–2013, which was implemented by the “V. Papantoniou” Peloponnesian Folklore Foundation (the project’s beneficiary) in Nafplio. The authors aim (a) to present the importance of reconstructing past cities and (b) to implement gaming technologies in cultural organizations as a means of achieve specific educational goals. Results point out the growing need for close cooperation between the cultural and academic worlds with 3D creators, and, moreover, reveal obstacles and opportunities in reconstructing historical cities and monuments.

Authors: Chen Feiyan , Li Ling , Niu Jiqiang , Lin Aiwen , Chen Shiyu , Hao Lin
Published: July 2019

The concept of ecosystem services (ES) supply and demand has attracted increasing attention in science and policy making because it effectively links ecosystem services to human well-being. The imbalance of ES supply and demand in urban areas has become a key issue in regional sustainable development. In this context, we calculated ES supply and demand for Wuhan City, China, using the ES supply and demand ratio (ESDR) and the comprehensive ES supply–demand ratio (CESDR) to express the relationship between ES supply and demand. Ecological zoning was proposed according to the spatial differentiation of the ES supply–demand relationship, and policy recommendations are made. The results show that from the perspective of total ES supply and demand, the water yield supply (SWY), grain yield supply (SGY), and recreation services supply (SRS) are greater than the water yield demand (DWY), grain yield demand (DGY), and recreation services demand (DRS), and that the climate regulation supply (SCR) is less than the climate regulation demand (DCR). From a spatial perspective, there are imbalances and mismatches in ES supply and demand, especially in urban central areas. The values of SWY, SGY, SCS, and SRS per unit area are less than their respective demand values, and the area of mismatch has expanded with the gradual increase of the built-up area. The spatial pattern of ES supply and demand is circular, with the form of “deficit zone–relative equilibrium zone–surplus zone”, which corresponds to “urban central area–near suburbs–distant suburbs and rural areas”.

The physiological role and relevance of the mechanisms sustaining circadian rhythms have been acknowledged. Abnormalities of the circadian and/or sleep-wakefulness cycles can result in major metabolic disorders or behavioral/professional inadequacies and stand as independent risk factors for metabolic, psychiatric, and cerebrovascular disorders and early markers of disease. Neuroimaging and clinical evidence have documented functional interactions between autonomic (ANS) and CNS structures that are described by a concept model (Central Autonomic Network) based on the brain-heart two-way interplay. The circadian rhythms of autonomic function, ANS-mediated processes, and ANS/CNS interaction appear to be sources of variability adding to a variety of environmental factors, and may become crucial when considering the ANS major role in internal environment constancy and adaptation that are fundamental to homeostasis. The CNS/ANS interaction has not yet obtained full attention and systematic investigation remains overdue.

Chronic inflammatory pain is one of the most common complaints that seriously affects patients’ quality of life. Previous studies have demonstrated that the analgesic effect of electroacupuncture (EA) stimulation on inflammatory pain is related to its frequency. In this study, we focused on whether the analgesic effects of EA are related to the period of stimulation. Purinergic receptor P2X3 (P2X3) is involved in the pathological process underlying chronic inflammatory pain and neuropathic pain. We hypothesized that 100 Hz EA stimulation alleviated Freund’s complete adjuvant (CFA) induced inflammatory pain via regulating P2X3 expression in the dorsal root ganglion (DRG) and/or spinal cord dorsal horn (SCDH). We also assumed that the analgesic effect of EA might be related to the period of stimulation. We found that both short-term (three day) and long-term (14 day) 100 Hz EA stimulation effectively increased the paw withdrawal threshold (PWT) and reversed the elevation of P2X3 in the DRG and SCDH of CFA rats. However, the analgesic effects of 100 Hz EA were not dependent on the period of stimulation. Moreover, P2X3 inhibition or activation may contribute to or attenuate the analgesic effects of 100 Hz EA on CFA-induced inflammatory pain. This result indicated that EA reduced pain hypersensitivity through P2X3 modulation.

With growing advances in three-dimensional (3D) printing technology, the availability and diversity of printing materials has rapidly increased over the last years. 3D printing has quickly become a useful tool for biomedical and various laboratory applications, offering a tremendous potential for efficiently fabricating complex devices in a short period of time. However, there still remains a lack of information regarding the impact of printing materials and post-processing techniques on cell behavior. This study introduces real-time live-cell imaging technology as a fast, user-friendly, and high-throughput screening strategy to verify the in vitro biocompatibility of 3D printed materials. Polyacrylate-based photopolymer material was printed using high-resolution 3D printing techniques, post-processed using three different procedures, and then analyzed with respect to its effects on cell viability, apoptosis, and necrosis of adipogenic mesenchymal stem cells (MSCs). When using ethanol for the post-processing procedure and disinfection, no significant effects on MSCs could be detected. For the analyses a novel image-based live-cell analysis system was compared against a biochemical-based standard plate reader assay and traditional flow cytometry. This comparison illustrates the superiority of using image-based detection of in vitro biocompatibility with respect to analysis time, usability, and scientific outcome.

Ceria/spinel-based lean NOx trap compositions with and without barium were modified with MnOx via incipient wetness impregnation. The effect of the MnOx layer on the aged materials (850 °C) as to the NOx storage and release properties was investigated via NOx adsorption (500 ppm NO/5% O2/balance N2) carried out at 300 °C in a dual-bed with a 1% Pt/Al2O3 catalyst placed upstream of the samples to generate sufficient amounts of NO2 required for efficient NOx storage. Subsequent temperature programmed desorption (TPD) experiments were carried out under N2 from 300 °C to 700 °C. The addition of MnOx to the barium free composition led to a slightly reduced NOx storage capacity but all of the ad-NOx species were released from this material at significantly lower temperatures (ΔT ≈ 100 °C). The formation of a MnOx layer between ceria/spinel and barium had a remarkable effect on ageing stability as the formation of BaAl2O4 was suppressed in favour of BaMnO3. The presence of this phase resulted in an increased NOx storage capacity and lower desorption temperatures. Furthermore, NOx adsorption experiments carried out in absence of the Pt-catalyst also revealed an unexpected high NOx storage ability at low NO2/NO ratios, which could make this composition suitable for various lean NOx trap catalysts (LNT) related applications.
Stainless Steel as A Bi-Functional Electrocatalyst—A Top-Down Approach

Published: July 2019

For a hydrogen economy to be viable, clean and economical hydrogen production methods are vital. Electrolysis of water is a promising hydrogen production technique with zero emissions, but suffer from relatively high production costs. In order to make electrolysis of water sustainable, abundant, and efficient materials has to replace expensive and scarce noble metals as electrocatalysts in the reaction cells. Herein, we study activated stainless steel as a bi-functional electrocatalyst for the full water splitting reaction by taking advantage of nickel and iron suppressed within the bulk. The final electrocatalyst consists of a stainless steel mesh with a modified surface of layered NiFe nanosheets. By using a top down approach, the nanosheets stay well anchored to the surface and maintain an excellent electrical connection to the bulk structure. At ambient temperature, the activated stainless steel electrodes produce 10 mA/cm2 at a cell voltage of 1.78 V and display an onset for water splitting at 1.68 V in 1M KOH, which is close to benchmarking nanosized catalysts. Furthermore, we use a scalable activation method using no externally added electrocatalyst, which could be a practical and cheap alternative to traditionally catalyst-coated electrodes.

Blast furnace slag, an industrial by-product, is emerging as a potential raw material to synthesize hydroxyapatite and zeolite. In this study, the effects of temperature on the hydrothermal synthesis of hydroxyapatite-zeolite from blast furnace slag were investigated. Specimens were synthesized at different temperatures (room temperature, 50, 90, 120, or 150 °C). The synthesized specimens were analyzed qualitatively and quantitatively via X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), BET/BJH, and scanning electron microscopy/energy dispersive using X-ray analysis (SEM/EDX). It was found that the hydroxyapatite phase was synthesized at all the reaction temperatures, while faujasite type zeolite appeared in the specimens synthesized at 90 and 120 °C. Moreover, faujasite was replaced by hydroxysodalite in the specimens synthesized at 150 °C. Additionally, the crystals of the hydroxyapatite tended to become larger and total crystallinity increased as the reaction temperature increased.
