Authors: Singh Sonia , Bajpai Meenakshi , Mishra Pradeep
Published: December 2021

The experimental study was designed to evaluate the in vitro antioxidant activity and hepatoprotective potential of ethanolic fruit extract of Pyrus pyrifolia (Burm.f.) Nakai. and Prunus avium Linn. in carbon tetrachloride (CCl4)-induced hepatotoxicity in rats. Pharmacognostic evaluation of fruits and their extracts was carried out according to the WHO quality control of herbal drugs. The antiradical activity of ethanol extracts of P. pyrifolia (Burm.f.) Nakai and P. avium L. was determined by using 2,2-diphenyl-1-picrylhydrazyl (DPPH), hydrogen peroxide (H2O2) and nitric oxide free radical scavenging assay. The Wistar albino rats were randomly divided into seven equal groups (n = 5). Group I was treated as normal control. Group II received 0.2% carbon tetrachloride (CCL4) in olive oil (8 mL/kg, i.p) on 14th day; Groups III as standard control contained silymarin (100 mg/kg, p.o) as standard drug once daily for 14 days. Group IV and V were given P. pyrifolia (Burm.f.) Nakai extract (200 and 400 mg/kg, p.o. in olive oil) for fourteen days; Group VI and VII received P. avium Linn. extract (200 and 400 mg/kg p.o. in olive oil) for fourteen days. Group III to VII animals were treated with 0.2% CCl4 in olive oil (8mL/kg, i.p) on the 14th day after the administration (1 hour) of the standard drug and test samples. Histopathological analysis and measurement of serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), total protein (TP), total albumin (TA) and total bilirubin (TB) were performed. Ethanol extract of P.avium L. demonstrated stronger antioxidant and higher total phenolic as well as total flavonoid content than P. pyrifolia (Burm.f.) Nakai. Both the extracts EEPP and EEPA (200 and 400 mg/kg) significantly normalized the CCl4-elevated levels of ALT, AST and ALP. P. pyrifolia (Burm.f.) Nakai and P. avium L. are the edible seasonal fruits that possessed an appreciable amount of phenolic and flavonoid components and could provide considerable protection against CCl4 hepatotoxicity in rodents that may be related to its antioxidant properties and also useful in preventing several degenerative and life threatening diseases.

Polycystic ovary syndrome (PCOS), an endocrinological disorder with lipid disturbances leads to a wide spectrum of clinical manifestations including menstrual irregularities, infertility, obesity and hyperandrogenism. This study aimed to determine the levels of lipid profile and sex hormones and its effect on PCOS from a State in southern India. This comparative hospital-based study was conducted in the State of Karnataka, India from June 2019 to January 2020. 57 age-matched PCOS and 67 healthy controls were enrolled for the study. Fasting glucose, insulin, lipid profile and sex hormone levels were analyzed after taking informed consent from all participants. The mean age of patients with PCOS was 25.05 ± 6.04 years and the mean age of subjects in the control group was 27.36 ± 7.08 years. Lipid profile showed statistically significant increased levels of triglyceride 147.3±86.6 (p<0.05) and decreased levels of HDL 52.2±8.7 (p<0.05) whereas hormones LH and testosterone were significantly higher in women with PCOS when compared to controls. The altered lipid profile, sex hormone and insulin levels exhibit a key role in the pathophysiology of PCOS that affects health. Insulin resistance is found to be linked with dyslipidemia in PCOS. Our findings suggest that the differences found may play a key role in the pathophysiology of PCOS which in turn affects the health and therefore it is advisable to emphasize the necessity for screening insulin resistance and perform early and periodic examination of lipid profile and sex hormones in women with PCOS to reduce complications.

Authors: Bansal Keshav , Bajpai Meenakshi
Published: December 2021

The present study was aimed to isolate and characterize mucilage obtained from the leaves of Amaltas (Cassia fistula) and to check the binding efficiency by comparing with gum acacia. Isolation of mucilage was done by hot maceration process and investigated for various physicochemical characterization and in vitro dissolution profile to check mucilage as a binding agent. Different batches (KF1 – KF4) of paracetamol tablets of different concentration of mucilage (3%, 5%, 10% and 15% w/v) were prepared by wet granulation method. All the parameters of uncoated tablets were performed and compared with tablets prepared with gum acacia in the same concentration. SEM indicated irregular shape and size of mucilage particles. Good thermal stability of mucilage was indicated by TGA and amorphous nature by P-XRD and DSC. FTIR and NMR confirmed the presence of polysaccharide. From the results, formulations KF2 and KF3 were found to be optimized as they showed 99% drug release within 20-25 min and better results were obtained when compared with existing binder gum acacia. According to the studies, mucilage isolated from the leaves of Cassia fistula showed interesting results suggesting that amaltas mucilage can be used as a promising natural excipient (binder) in preparation of conventional uncoated tablet dosage form.

Published: December 2021

Cellulases are one of the important groups of industrial hydrolases which hydrolyze lignocellulosics into glucose, hence find numerous applications in the food, feed and beverage industry, textile, pulp and paper industry and biofuel production. With a view of industrial importance of cellulases, this study aimed to screen the cellulolytic potential of fungus Thermomucor indicae-seudaticae sp. nov. The zone of cellulose hydrolysis producing around the growth of fungus confirmed its cellulase-producing ability. Further, the enzyme production was carried out under liquid fermentation and various culture conditions were optimized. Among the physical conditions, maximum enzyme production was obtained at pH 7.0, incubation temperature of 50°C and incubation period of 7 days. Corn cob as carbon source followed by rice straw enhanced the enzyme production. Yeast extract was found to be the best nitrogen source. The crude enzyme exhibited highest enzyme activity at pH 7.0 and temperature 45oC. Among the various additives tested, some metal ions (Na+, K+, Ca+2 and Mg+2) stimulated the enzyme activity while Hg+2 strongly inhibited the enzyme. Among the detergents, SDS had stimulatory effect while Triton X-100 was found inhibitory for cellulase.

Where did the Eco go in Systemic Practice?
Authors: Palmer Hugh
Published: December 2021

In this paper, I argue that, although the systemic therapy community adopted some of Gregory Bateson’s ideas, we neglected his ecological concerns, and his thinking about epistemology and ontology might have shaped our practice even more than the comparatively few concepts we took. With rising concerns about the impact of humans upon the environment in the era in which we live, described as the Anthropocene, along with the posthuman turn, perhaps now is the time for us to look both backwards and forwards to deepen our understanding of Bateson’s message; to acknowledge the continuing importance of his thinking and influence upon the posthumanities.

A local three-dimensional variational data assimilation (DA) system was implemented operationally in AROME/HU (Application of Research to Operations at Mesoscale) non-hydrostatic mesoscale model at the Hungarian Meteorological Service (OMSZ) in 2013. In the first version, rapid update cycling (RUC) approach was employed with 3-hour frequency in local upper-air DA using conventional observations only. Optimal interpolation method was adopted for the surface data assimilation later in 2016. This paper describes the current developments showing the impact of more conventional and remote-sensing observations assimilated in this system, which reveals the benefit of additional local high-resolution observations. Furthermore, it is shown that an hourly assimilation-forecast cycle outperforms the 3-hourly updated system in our DA. Besides the upper-air assimilation developments, a simplified extended Kalman filter (SEKF) was also tested for surface data assimilation, showing promising performance on both the analyses and the forecasts of AROME/HU system.
Calibration of wind speed ensemble forecasts for power generation
Authors: Baran Sándor , Baran Ágnes
Published: December 2021

In the last decades, wind power became the second largest energy source in the EU covering 16% of its electricity demand. However, due to its volatility, accurate short range wind power predictions are required for successful integration of wind energy into the electrical grid. Accurate predictions of wind power require accurate hub height wind speed forecasts, where the state-of-the-art method is the probabilistic approach based on ensemble forecasts obtained from multiple runs of numerical weather prediction models. Nonetheless, ensemble forecasts are often uncalibrated and might also be biased, thus require some form of post-processing to improve their predictive performance. We propose a novel flexible machine learning approach for calibrating wind speed ensemble forecasts, which results in a truncated normal predictive distribution. In a case study based on 100m wind speed forecasts produced by the operational ensemble prediction system of the Hungarian Meteorological Service, the forecast skill of this method is compared with the predictive performance of three different ensemble model output statistics approaches and the raw ensemble forecasts. We show that compared with the raw ensemble, post-processing always improves the calibration of probabilistic and accuracy of point forecasts, and from the four competing methods, the novel machine learning based approach results in the best overall performance.
Effect of the uncertainty in meteorology on air quality model predictions
Authors: Ferenczi Zita , Homolya Emese , Lázár Krisztina , Tóth Anita
Published: December 2021

An operational air quality forecasting model system has been developed and provides daily forecasts of ozone, nitrogen oxides, and particulate matter for the area of Hungary and three big cites of the country (Budapest, Miskolc, and Pécs). The core of the model system is the CHIMERE off-line chemical transport model. The AROME numerical weather prediction model provides the gridded meteorological inputs for the chemical model calculations. The horizontal resolution of the AROME meteorological fields is consistent with the CHIMERE horizontal resolution. The individual forecasted concentrations for the following 2 days are displayed on a public website of the Hungarian Meteorological Service. It is essential to have a quantitative understanding of the uncertainty in model output arising from uncertainties in the input meteorological fields. The main aim of this research is to probe the response of an air quality model to its uncertain meteorological inputs. Ensembles are one method to explore how uncertainty in meteorology affects air pollution concentrations. During the past decades, meteorological ensemble modeling has received extensive research and operational interest because of its ability to better characterize forecast uncertainty. One such ensemble forecast system is the one of the AROME model, which has an 11-member ensemble where each member is perturbed by initial and lateral boundary conditions. In this work we focus on wintertime particulate matter concentrations, since this pollutant is extremely sensitive to near-surface mixing processes. Selecting a number of extreme air pollution situations we will show what the impact of the meteorological uncertainty is on the simulated concentration fields using AROME ensemble members.

Published: December 2021

The high cost of energy consumption in buildings highlights the importance of research focused on improving the energy efficiency of building’s envelope systems. It is important to characterize the real behavior of these systems to know the effectiveness in terms of energy reduction. Therefore, the aim of this paper is to characterize the thermal performance of facades based on experimental monitoring of outdoor test cells in tropical climate. To carry out this research, a case study was presented to compare two construction systems. One of them is a light façade (M1) and the other a reference façade (M2). A thermal simulation was performed for the opaque and glazed facades. In addition, several parameters were measured with different types of sensors, as well as environmental variables to evaluate the thermal and lighting behavior of multiple facades systems under real conditions. The findings show that light façade behavior was the opposite of what was expected, since by incorporating a window in the façade it has allowed solar radiation to increase the interior temperature in both modules. In the case of the light facade the penalization was higher than the reference facade, which has a lower thermal transmittance than M1. Doi: 10.28991/cej-2021-03091773 Full Text: PDF

Authors: Daddow Mohammad , Zhou Xinglin , Naji Hasan A.H. , Ayasrah Mo'men
Published: December 2021

The safety and continuality of the railway network are guaranteed by carrying out a lot of maintenance interventions on the railway track. One of the most important of these actions is tamping, where railway infrastructure managers focus on optimizing tamping activities in ballasted tracks to reduce the maintenance cost. To this end, this article presents a mixed integer linear programming model of the Tamping Planning Problem (TPP) and investigates the effect of track segmentation method on the optimal solution by three scenarios. It uses an opportunistic maintenance technique to plan tamping actions. This technique clusters many tamping works through a time period to reduce the track possession cost as much as possible. CPLEX 12.6.3 is used in order to solve the TPP instances exactly. The results show that the total number of machine preparations increases by increasing the number of track segments. It is also found that the total costs increase by 6.1% and 9.4% during scenarios 2 and 3, respectively. Moreover, it is better to consider the whole railway track as a single segment (as in scenarios 1) that consists of a set of sections during the tamping planning in order to obtain the optimal maintenance cost. Doi: 10.28991/cej-2021-03091774 Full Text: PDF
Evaluating the Friction Characteristics of Pavement Surface for Major Arterial Road
Authors: Mohammad Diana Jumah , Ismael Mohammed Qadir
Published: December 2021

The performance of the pavement in terms of vehicle safety and tire wear is affected by the friction behavior of the pavement. To highlight the main characteristics that affect the production of better friction resistance of the pavement surface in this work. The micro-texture and macro-texture of the asphalt surface of Baghdad Airport highway were studied using two methods: (sand patch method and the British pendulum test). The sand patch was examined by drawing sand grains of a specific volume, while the micro-texture was analyzed using a BPT under dry and wet surface conditions. All data obtained from the two examinations were analyzed and modelled statistically using SPSS 25 software. Results show that skid resistance of pavement surface increase with the increase of MTD, this increase may be due to the increase of coarse aggregate which lead to increase the roughness of the pavement surface, this increase ranged between (96 - 91%). MTD decreases with the increase of traffic flow due to the friction between the road surface and the vehicle tires leading to increase of smoothness of the road surface. This is mean that MTD is highly affected by the traffic flow and this effectiveness ranged between (84-97%). Skid resistance also is highly affected by the traffic flow with an effectiveness ranged between (81-94%) for both pavement conditions. According to the regression analysis for friction and other parameters, it can be concluded that surface friction values are highly affected by cumulative traffic (asphalt mix deterioration) over time. Doi: 10.28991/cej-2021-03091775 Full Text: PDF
The Effect of Adding Fibers on Dry Shrinkage of Geopolymer Concrete
Authors: Frayyeh Qais J. , Kamil Mushtaq H.
Published: December 2021

Despite their drastically different chemical ingredients and interactions, geopolymer concrete exhibits many of the same features as ordinary concrete. Among these properties is drying shrinkage. As in normal concrete, dry shrinkage in geopolymer concrete may cause cracking if the geopolymer concrete is bound, which affects the integrity of the structure in the future. It's important to measure drying shrinkage as soon as possible because it's the cause of early age cracking, which happens when the concrete isn't very strong. The purpose of this study is to determine how to reduce the dry shrinkage value of geopolymer concrete by using different types of fibers. Three types of fibers were used to determine their effect on the dry shrinkage of geopolymer concrete when compared with a reference mixture without the fibers. Metakaolin was used as a binder for the concrete geopolymer. As for the fibers, steel, carbon and polypropylene fibers were used in proportions of (0, 0.5, and 1%). The results showed an improvement in dryness shrinkage when adding fibers in general, with a difference in values between the different types of fibers. Steel fibers had the lowest amount of dry shrinkage. The temperature had a direct influence on the decrease in the extent of the shrinking, since the samples handled at higher temperatures had less dryness to begin with. Doi: 10.28991/cej-2021-03091780 Full Text: PDF
Methodology of allocation of costs for the introduction of new and modernization of existing technologies for the production cost of products in the conditions of sustainable development of an industrial enterprise
Authors: Mizikovskiy Igor'
Published: December 2021

One of the important tools for incorporating the paradigm of sustainable development into the complex fabric of economic activity of an enterprise in the real sector of the economy is the permanent process of introducing new and updating existing production technologies. Managing this difficult process requires fundamental changes in the traditional approach to structuring the information and tool space of the accounting and calculation process of forming the production cost of products. The solution of this difficult task involves the decomposition of the pool of indirect costs in order to allocate from its composition the costs of introducing new and upgrading used technologies and then assigning them to the production cost. It should be noted that these costs are distributed in proportion to the quantitative characteristics of material cost savings. The choice of this indicator as a distribution base is justified by the fact that it is one of the key components of the economic benefits coming to the enterprise. In the course of the study, various methods were used comprehensively, including: observation, systematization, formalization, modeling and visualization, decomposition and aggregation of data. The results obtained in the course of the study will improve the quality of the information and instrumental space for making managerial decisions aimed at ensuring the sustainable development of economic entities in the real sector of the economy by updating existing and introducing new, advanced production technologies.

The strategic directions of Russia's economic development presuppose the existence of state programs, the transition from the expert-raw material type to the innovative type. A qualitatively new level of information processing opens up new development opportunities as a result of an increase in the speed of information processing throughout the entire life cycle of agricultural production. Sustainable development is measured by production on the territory and its efficiency in relation to the country's food security. Since the territories are not only producers of products, but also a complex socio-economic structure that functions according to certain laws, rules and traditions, a kind of habitat for residents. To a large extent, the sustainable development of territories depends on the level of development of production, implements the sustainable development of the economy. The state regulates the sustainable development of territories in order to support production as the main element of processes, controlling its development, supporting domestic producers, and performs one of the most important state functions, which is a macroeconomic problem of research of the territorial complex. Consequently, there is a dialectical relationship between the process of economic stabilization and the sustainable development of territories, which requires the development of research approaches. The search for new approaches to the development of territories is a particularly important circumstance at the present stage. A full-fledged system of economic, mathematical, structural modeling allows us to obtain predictive estimates in the context of food security indicators, based on current trends, global challenges and changes.

Published: December 2021

The article compares indicators characterizing the achievement of sustainable development goals in the framework of national projects for two regions - Nizhny Novgorod and Moscow regions, which differ in the degree of urbanization. The Nizhny Novgorod region is inferior to indicators, both in the Russian Federation and in the Moscow region. Lagging behind the Nizhny Novgorod region in the main targets will require more efforts in achieving development goals. Analysis of changes in the administrative structure of rural territories of the regions for 2011-2020 showed that the enlargement of municipalities and the creation of urban and municipal districts accelerates the formation of rural-urban territories. In the Moscow region, rural settlements were completely eliminated, urban districts were created. Sustainability of rural development is defined as a complex concept, stable state and balanced harmless use of resources in each of the interconnected areas of development. There are an organization, an environment, a territory.

Authors: Semenova Elena
Published: December 2021

The growth of agricultural exports is due to a focused state policy that ensures the development of the Russian agro-industrial complex. The mechanisms used to stimulate agricultural and food exports are divided into general (federal) and individual financial and non-financial support instruments (regional), have different degrees of demand by agricultural producers and different regional involvement in their application. There was an increase in exports, a low share in the export of deep processing products, a discrepancy between the placement of agricultural production and the structure of exports, an expansion of state support measures, their positive and negative impact on the market, various regional involvement in export processes, and a high concentration of exports in the Rostov region.

Authors: Domenko Yuriy
Published: December 2021

To date, the Russian Federation has created and is actively developing a system of strategic planning of socio-economic development, including subjects, objects, strategic documents, tools, regulatory and methodological framework, as well as a number of other elements. Despite the institutional formation, there are still quite a few problems in this system, especially at the regional level. The subjects of the Russian Federation have strategic documents at their level, the purpose of which is the socio-economic development of the region. Despite this, the quality of strategic documents is not always at a high level. First of all, the quality of strategic documents is influenced by a set of tools that allow you to achieve your goals and objectives. Within the framework of this study, a method of correlation and regression analysis is proposed in the system of strategic planning tools at the stage of determining priority areas.

İnsan, yaradılışından itibaren hayatını idame ettirmek amacı ile doğada bulduğu hammaddeleri şekillendirerek çeşitli araç gereçler ortaya koymuştur. Önceleri acemice ortaya konan ürünler, artan deneyimler ile birlikte yetenekli ustaların ellerinde daha kullanışlı hale gelmiştir. İlerleyen süreçte neredeyse her bir ürün için farklı teknikler uygulanmaya başlanmış ve bunun sonucunda çeşitli el sanatı kolları doğmuştur. Geleneksel kültürün maddi yansımaları olan el sanatları, herhangi bir şekli olmayan ağaç, maden, deri, toprak, hayvansal ve bitkisel lif gibi malzemelerin çeşitli araçlar yardımı ile elde şekillendirilmesi sonucunda ortaya konan eserlerden meydana gelir. Usta çırak ilişkisine dayalı olarak yapılan bu üretimlerde kullanılan yöntemler ve araç gereçler, nesilden nesle aktarılarak gelenekselleşmiş ve günümüze ulaşmıştır. İnsanların çeşitli ihtiyaçlarına cevap veren ve yaşamlarını kolaylaştıran bu eserler, kişilerin zevk, beğeni ve duygularını yansıtmalarının yanı sıra yapıldıkları dönemin yaşam biçimlerinden de izler taşır. Geleneksel Türk sanatları, asırlardır kullanılan üretim teknikleri ile sınırlı sayıda kültür taşıyıcısı tarafından sürdürülmeye çalışılmaktadır. Kültürel miras kapsamında değerlendirilen el sanatları arasında; demircilik, hallaçlık, hasırcılık, sepetçilik, keçecilik, dokumacılık, saraçlık, çömlekçilik vb. alanlar yer almaktadır.
