Published: March 2021

Pengolahan buah stroberi dengan teknik pengeringan lazimnya dilakukan untuk tujuan memperpanjang umur simpan. Pada penelitian ini, bubuk minuman instan stroberi dibuat melalui proses foam-mat drying pada suhu 50 oC melalui penambahan putih telur 10% (b/b) sebagai agen pembuih, maltodekstrin 12 % (b/b) dan Tween 80 0,1% (b/b) sebagai stabilizer buih pada sari buah stroberi. Penelitian ini bertujuan untuk menentukan umur simpan bubuk minuman stroberi instan dengan menggunakan metode ASLT (Accelerated Shelf Life Testing) berdasarkan model persamaan Arrhenius. Bubuk minuman instan stroberi disimpan pada suhu penyimpanan 35, 45, dan 55 oC dengan waktu penyimpanan 15 hari. Kadar air, vitamin C dan skor mutu hedonik warna diamati tiap 3 hari. Hasil percobaan menunjukkan hubungan yang linier antara kenaikan kadar air, penurunan kadar vitamin C, dan penurunan skor mutu hedonik warna terhadap waktu penyimpanan pada masing-masing suhu penyimpanan. Umur simpan produk bubuk minuman instan stroberi yang disimpan pada suhu penyimpanan 35, 45, dan 55 oC, menunjukkan hasil berdasarkan kadar air (11, 10, dan 9 hari), vitamin C (779, 773, dan 766 hari) dan mutu hedonik warna (35, 30, dan 26 hari) secara berurutan. Kesimpulannya, umur simpan dapat ditentukan pada minuman instan stroberi dengan menghasilkan nilai yang spesifik tergantung pada parameter yang diteliti.Shelf-life Determination using Accelerated Shelf Life Test (ASLT) Method for Foam-Mat Drying Instant Drink Strawberry PowderAbstractProcessing of strawberry through drying method is designed to prolong its shelf life.

The Role of Apathy in the Formation of Depression Syndrome in Male Prisoners
Authors: Zolotareva A.A.
Published: March 2021

The article presents the results of a research work on the role of apathy in the formation of depression syndrome in male prisoners. Basing on the questionnaire polling results of men (N = 151) serving their sentences in one of the maximum security penal colonies in Omsk, an empirical model was built indicating that the formation of depression syndrome in male prisoners is a complex step-by-step process with early stages involving manifestation of hopelessness, boredom and loneliness and with apathy joining in at later stages. The analysis of social and demographic characteristics revealed that a prisoner's age, family situation, children, education, the sentence served or the charges of which he was convicted have no effect on his psychological symptoms (the prisoners' educational level is only found to influence the way hopelessness is experienced). The data obtained suggest that there is a necessity for educational activities in prisons and also indicate a potential utility of the results in the field of anti-crysis therapy for prisoners in Russia.
Specifics of Sexual Self-Concept and Interpersonal Perception in Convicted Non-Imprisoned Sexual Offenders
Authors: Dvoryanchikov N.V. , Shipitsyn D.Y.
Published: March 2021

The article considers the specifics of the sexual self-concept and interpersonal perception in individuals convicted of sexual crimes and serving their sentences without legally imposed loss of freedom. The study was aimed at revealing the structure of intact and damaged elements of the sexual self-concept in this category of persons and the correspondence between this self-concept and the properties found in appetence disorders. The sample consisted of 60 persons: 30 of them were registered (at the time of the study) with Penal Enforcement Inspectorates of the Federal Penal Correction Service for committing sexual offences (without loss of freedom) and had no revealed mental pathology, whereas the other 30 persons had neither criminal records nor any revealed mental disorders. The techniques used were "Masculinity and Femininity", "Age Identity", "The Color Relationship Test", "Encoding". The research work had an increased emphasis on the qualitative analysis of associative images. From the results of an empirical study it was shown that the make-up of the sexual self-identity in a large proportion of the convict subjects has the nature of anomalous necessity, which poses the risk of repeated offences. The results of the study suggest the necessity to make recommendations for the judiciary about referral of this category of persons for a forensic examination of their mental condition. The psychologists of penal enforcement inspectorates were recommended to implement the techniques of diagnosing one's sexual self-concept as part of their day-to-day work on differentiating convicts by the risk they pose.
Legal Conscience of Teens from the Centennials Generation: a Prognostic Assessment
Authors: Boykina E.E. , Chernov V.A.
Published: March 2021

Adolescence is a sensitive period for setting the groundwork of one's legal conscience on the way to the legal culture of an adult. The article analyses the projected risks for shaping the legal conscience of people for the next 10-20 years using the approach of the modern theories of generational cohorts. For the purpose of "detailed portrayal" of the anticipated image of an adult from the 2030-2040 this article contains the results of 11 studies (on centennials, iGeners, homelanders, digital natives etc.). The disputable traits of the typical representatives of these generations (that can potentially have impact on the formation process of their legal conscience) are compared: the idea of authority, the new forms of communication and education, hedonism, multitasking, planning horizon, family values etc. A number of features of the modern generation are compared with the fundamental elements of the structural and functional model of legal conscience (Ratinov A.P), particularly from the viewpoint of some systems: cognitive, regulative and evaluation. The postulates of the generation theories are critically assessed. We also analyse the general tendencies for the interaction of generations from the perspective of legal socializing.
A Seismic Intensity Survey of the 16 April 2016 Mw 7.8 Pedernales, Ecuador, Earthquake: A Comparison with Strong-Motion Data and Teleseismic Backprojection
Authors: Smith Ellen M. , Mooney Walter D.
Published: March 2021

We conducted a seismic intensity survey in Ecuador, following the 16 April 2016 Mw 7.8 Pedernales earthquake, to document the level of damage caused by the earthquake. Our modified Mercalli intensities (MMIs) reach a maximum value of VIII along the coast, where single, two, and multistory masonry and concrete designed buildings partially or completely collapsed. The contours of our MMI maps are similar in shape to the contour maps of peak ground acceleration (PGA) and peak ground velocity (PGV). A comparison of our seismic intensities with the recorded PGA and PGV values reveals that our MMI values are lower than predicted by ground-motion intensity conversion equations that are based on shallow crustal earthquakes. The image of the earthquake rupture obtained using teleseismic backprojection at 0.5–2.0 Hz is coincident with the region of maximum MMI, PGA, and PGV values, Thus, rapid calculation of backprojection may be a useful tool for guiding the deployment of emergency response teams following large earthquakes. The most severe damage observed was, primarily, due to a combination of poorly constructed buildings and site conditions.
Role of Pyrroloquinoline Quinone in Biocontrol Together with Induced Systemic Resistance: A Novel Resource Trialed for Rice Disease Control
Authors: Naveed Muhammad
Published: March 2021

Plants show strong levels of resistance to an extensive range of pathogens on account of root colonization through plant growth-promoting rhizobacteria (PGPR), namely, induced systemic resistance (ISR). Little is known about bacterial determinants and plant signaling pathways that underpin ISR in cereal crops associated with ISR in dicotyledonous plants. The present study evaluates the potential of Pseudomonas spp. QAU-92 using site directed mutagenesis of the pqqC gene to elicit ISR in rice (Oryza sativa L.) against the fungal pathogen Cochliobolus miyabeanus. The comparison between the wild-type strain and the mutant strain for biochemical attributes, in vitro and in vivo antagonistic activity, carbon source utilization assay and in vivo analyses on rice (cv. C-039) revealed the statistically significant role of Pyrroloquinoline Quinone (PQQ) in plant growth promotion. RT-qPCR analysis revealed that the plant recognition of QAU-92 results in the activation of ethylene (ET) and jasmonic acid (JA) pathways and also shows clear differences in resistance against C. miyabeanus disease compared with the pqqC mutants (QAU92-2). The expression of TF 89 (EBP89), a susceptible gene, as well as the pathogenesis-related protein 1a (PR1a) were much higher in the infected control and pqqC mutant plant than in wild type inoculated plants. Hence, this study is the first of the kind that has investigated the expressional analysis of PQQ against antifungal activity, phosphate solubilization and the induced systemic resistance of QAU-92 against C. miyabeanus in rice. Additionally, PQQ genes may act as a key regulator of PR1a/ET cross-talk and its interference with the fungal manipulation of plants. © 2021 Friends Science Publishers
Performance and Economic Prospect of Pigeonpea Varieties in Pigeonpea-Maize Strip Intercropping in Limpopo Province
Authors: Akanwe Asiwe Joseph Nwafor
Published: March 2021

Pigeonpea is an important grain legume, and is traditionally intercropped with maize in West Africa and India. Small farmers in Limpopo Province, South Africa, who cultivate pigeonpea landraces under traditional mixed intercropping, experience the challenge of low productivity. Strip intercropping is a novel cropping system has greater efficiency and productivity in resource utilization when compared to mixed intercropping. Therefore, this study was conducted to evaluate the performance of improved pigeonpea varieties under a pigeonpea-maize strip intercropping system. Five pigeonpea varieties (ICEAP 001284, ICEAP 00604, ICEAP 87091, ICEAP 00661 and ICEAP 01101-2) were intercropped in maize as mixed and strip intercropping during the 2015–2016 and 2016/2017 cropping seasons while monocrops of both crops were also maintained as control. The trial for each season was replicated three times in a split plot design. During both seasons, ICEAP 001284 and ICEAP 00604 exhibited the shortest number of days to attain 50% flowering under strip intercropping and monocropping when compared to the remaining varieties. Higher significant (P < 0.05) grain yields (1726 kg ha-1, 1478 kg ha-1 and 858 kg ha-1 were obtained under strip intercropping for ICEAP 001284, ICEAP 01101-2 and ICEAP 00604, respectively during 2016/2017 than their respective grain yields during 2015/2016 season. Strip intercropping out-performed mixed intercropping with a higher land equivalent ratio and cash returns due to its ripple effect in the enhanced yield components. Among the five pigeonpea varieties, ICEAP 001284, ICEAP 00604 and ICEAP 01101-2, performed exceedingly well in their crop mixtures. In conclusion, the three pigeonpea varieties were selected for cultivation under strip intercropping. Strip intercropping exhibited greater efficiency in resource utilization and productivity over mixed intercropping in terms of grain yield, land equivalent ratio, net profit, and benefit-cost ratio. © 2021 Friends Science Publishers
Planting Density and Variety Modulated Root and Leaf Characteristics to Improve Grain Yield of Spring Maize
Authors: Yang Qinglong
Published: March 2021

To better understand the accumulation and transport of substances under different planting densities, the adaptation of maize root and leaf in response to increasing planting densities was investigated. In this two-year filed study, three maize varieties, Fumin108 (FM), Xianyu335 (XY) and Dika159 (DK), were sown under three different planting densities: 15,000 (D1), 60,000 (D2) and 90,000 plants ha-1 (D3) during 2018 and 2019. Increase in planting density gradually increased leaf area index along with reduced leaf area and net photosynthetic rate of individual leaves. In the 0–20 cm soil layer, the average root dry matter decreased by 55.88 and 80.92%, and the average root number decreased by 31.18 and 38.71% under D2 and D3, respectively, compared with D1. With increase in planting density, yield and dry matter per plant of maize gradually decreased while yield and dry matter per ha was increased with increase in D1-D2 density and then flattened in D2-D3 density. Compared with D1, two-year average yield per plant was decreased by 34.10 and 51.87% under D2 and D3, respectively. The difference in the number of roots of XY, FM and DK were not significant, so change in variety did not alleviate the decrease in the number of roots. At higher planting densities (above D2), the increase in density did not increase per ha grain yield. In conclusion, the suitable plant density was about 60,000 plants ha-1 to harvest more yield of spring maize while density higher than that reduced leaf area and photosynthesis per plant. Moreover, leaf area, root number and net photosynthesis per plant was higher in lower planting density coupled with overall less yield on ha basis and thus seemed wastage of soil nutrients and light resources. © 2021 Friends Science Publishers
Identification of Local Citrus Breeds Using the Start-Codon Targeted Polymorphism Technique Combined with Clonal Sequencing
Authors: Guo Yanjun
Published: March 2021

This study explored the genetic diversity of 35 citrus accessions using start-codon targeted (SCoT) markers. Total 15 primers were used to amplify products ranging in length from 100 to 2000 bp. A total of 133 fragments were amplified and found that 126 (95%) were polymorphic. The genetic similarity coefficients among the 35 accessions ranged from 0.67 to 1.00, indicating that the SCoT markers could reveal high genetic diversity in the citrus germplasm. A cluster analysis showed that local citrus breeds of Sihui city fell into one cluster, possibly reflecting the geographical distribution of the tested samples. The sizesof the fragments of eight local citrus cultivars amplified by one of the primers ranged from 951 to 1001 bp, and the similitude was 95.17%high. Both single-base mutations, insertions and deletions were identified among the fragments and comparison with asequence database suggested that the amplified region was part of a ribosomal protein-coding sequence. Using Scot marks combined with clonal sequencing, each of the test samples had one or more mutation sites that could be used as markers to differentiate from the other seven test samples. Thus, the resolution of the genetic diversity among the local citrus breeds revealed by the SCoT technique was enhanced by the subsequent sequencing analysis of specific fragments. The experimental results also provide evidence that the relationship between CitrusnobilisL our. ‘gonggan’ and C. hanianaHort. ex Tseng ‘Sihuihanggan’ is that between parent and offspring hybrids and not between bud-mutation strains. The SCoT marker is a targeted gene molecular marker, based on the characteristic bands of primers, it can be used as a marker to isolate genes of local citrus varieties and also for investigating mutational hotspots of the segene.© 2021Friends Science Publishers
Effects of Dietary Tea Polyphenols on Epigallocatechin Gallate, Catechin, Egg Quality and Production of Gallus domestiaus
Authors: Fan Zhenzhen
Published: March 2021

Effect of dietary tea polyphenol (TP) on the content of epigallocatechin gallate (EGCG), catechin (C) in egg yolk, and impact on egg quality and production was investigated. For this purpose, 315 healthy Gallus domestiaus aged 42 weeks were selected and randomly divided into 7 groups. The experimental group added 0.02, 0.05, 0.09, 0.14, 0.19 and 0.24% TP to the basic diet. The control group (CK) was fed basal diet. After 10, 20 and 30 days, 15 eggs were randomly selected from each group for egg quality testing, and 20 eggs were selected for EGCG and C content test in the yolk. The results showed that in the 0.24% TP group, the content of EGCG in egg yolk was significantly higher than that of CK group and the 0.02, 0.05, 0.09 and 0.14% TP groups (P < 0.05), and reached the highest on the 30th day (19.171μg/g). The content of C in egg yolk was significantly higher than that in CK group and the 0.02, 0.05, 0.09 and 0.14% TP groups (P < 0.05); and reached the highest on 30th day (7.071 μg/g). The egg weight of the 0.14% TP group on the 10th day and of the 0.19% TP group on the 20th day were significantly lower than that of the CK group (P < 0.05); the egg yolk weight of 0.14% TP on the 10th and 20th days were significantly lower than that of the CK group (P < 0.05). On the 30th day, compared with the control group, the egg weight of the 0.14% TP group was significantly reduced (P < 0.05), the egg yolk color of 0.05 and 0.14% TP groups was significantly increased (P < 0.05). During the whole experiment, the egg production of 0.24% TP group was significantly higher than that of control group (P < 0.05). In conclusion, adding high concentrations of TP can increase the content of EGCG and C in the yolk; however, it has a certain impact on egg weight, yolk color and eggshell thickness. Adding high concentrations of TP may increase egg production. © 2021 Friends Science Publishers
Para uma análise linguística do conto "Sobre da morte de Bieito" de Rafael Dieste: referenciação, enunciação e modalidade
Authors: Moreira Benjamim
Published: March 2021

Um texto é susceptível de aprimorar a sua análise literária com a ocorrência de uma análise linguística. Embora ambos os tipos de estudos não persigam os mesmos objectivos, e apesar de o texto literário ter sido muito recorrentemente utilizado para exemplificar fenómenos linguísticos investigados ou para formular teorias sobre a linguagem, um lingüista, perante um produto literário, pode deitar luz precisa sobre noções tais como o plano histórico ou referencial, o plano enunciativo e o plano modal com que foi construído o tal produto estético. O meu artigo, partindo do conto de Rafael Dieste “Sobre da morte do Bieito”, pretende ilustar como uma análise linguística centrada na refenciação, enunciação e modalidade textuais serve de eficaz ajuda à compreensão do texto literário.

Review of Crip Camp co-directed by James LeBrecht and Nicole Newnham
Authors: Sedgwick Marrok
Published: March 2021

Crip Camp (2020) follows the structure of a well-made film (Simon, 1972), and echoes the social issue film genre (Byars, 1991), thereby telling a clear, chronological story that reifies conservative family values as the solution to challenges faced by society. Through this structure, it fails to push for the change it claims to seek, while presenting content that objectifies people with cognitive disabilities, minimizes the contributions of Black disabled people and LGBT+ disabled people, and erases the voices of non-Black disabled people of color. Crip Camp fails to use the medium of film to present (through tools of filmmaking and the content within) alternative interdependent maps (Mitchell & Snyder, 2017), or reimagine what society can be.

AWARENESS OF EARLY CHILDHOOD EDUCATIONAL MANAGERS ABOUT TRANSITION FROM HOME TO KINDERGARTEN
Authors: Tran Thi Kim Lien
Published: March 2021

The article presents a survey results on the awareness of early childhood education managers of supporting children in the transition period from home to kindergarten through questionnaire filled by 213 managers in some provinces and cities in Vietnam. The results showed that the managers were initially aware of the transition from home to kindergarten such as the time and way of transition. However, they concerned much more with the aspect of “ready schools” than “ready families” or “ready children”. Although managers were aware of the role of parents in the transition from home to kindergarten, the ways which parents supported their children were not considered. In addition, factors related to the children such as development levels and abilities were lacked of attention. Therefore, the school's transition support activities were not diversified, which didn’t pay much attention to the participation of families and children by their own. The results also affirmed that it has been many difficulties and barriers from families and communities in the transition period from home to kindergarten of children.

Reinforced Concrete Design of Tall Buildings According to the Turkish Earthquake Code
Authors: TUNÇ Gökhan , TANFENER Tuğrul
Published: March 2021

The new Turkish earthquake code (TEC 19) is primarily based on Performance Based Seismic Design, and includes elements from the “Guidelines for Performance-Based Seismic Design of Tall Buildings,” a code published by the Pacific Earthquake Engineering Research Center in the United States. This article studies the advantages and disadvantages of TEC 19 with respect to the preexisting code (TEC 07), and the impact of the new code on the design of high rise buildings. In order to understand the effects of the new code, two 30 story residential buildings—one constructed using tunnel formwork, and the other with special moment resisting frames—were designed according to TEC 19 and TEC 07. The design results of the earthquake analyses were used to understand the impact of TEC 19 on high rise buildings, since these buildings with similar framing systems are now commonly being built in most of the major cities of Turkey. The analyses also included the total base shear, axial forces, shear forces, and bending moments of some structural members. Based on the design results, it was observed that the new code generally generated higher earthquake forces on both buildings with tunnel formwork and special moment framing system.
The Success of Restricted Ordination Methods in Data Analysis with Variables at Different Scale Levels
Authors: HUYUT Mehmet Tahir , KESKİN Sıddık
Published: March 2021

Events in nature occur with the effect of many interrelated variables, either separately or together. It is important to introduce and use the methods used for the analysis of data sets at different scale levels with linear and nonlinear relationship structure between variables. Redundacy Analysis and Canonical Correspondence Analysis are among the methods used in the analysis of such data. Aforementioned techniques are generally carried out by ecologists and there are limited studies in the field of health. In the study, the application of the methods was performed with a data set in the field of Cardiology including variables at different scale levels and their performances were compared. Determination Coefficient (R2) and MAPE (Mean Absolute Percentage Error) value were calculated as performance criteria. According to the results, it was seen that CCA and RDA, which analyze the relationship structures between variables in different scale types (cardiological data set), explain the variation sufficiently. Also, it was emphasized that both methods classify well with low MAPE value (less than 10%) and perform ordination diagram. In addition, it has been observed that restricted ordination diagram models give satisfactory results in determining the relationships between coronary heart disease data and so that they can be used in the field of health too.

Published: March 2021

In Europe, 70% of citizens live in urban areas and consume around 75% of the primary energy supply. In order to reduce the impact of energy consumption and improve the competitiveness of local energy systems, Energy Communities may help to address the challenges of urban sustainability and energy security through local energy production and self-consumption. Solar, biomass and wind are the main sources of renewable energy that are generally used in cities. However, not all the sources available in urban environment are usable, due to the limited availability, or other technical or non-technical limits and constraints. In order to promote renewable energy technologies in buildings it is necessary to consider architectural, cultural, energy, technical and economic feasibility. This work defines a methodology for the optimal design of grid connected PV-battery systems in urban environments. The model was applied to two districts located in the city of Turin with the aim of evaluating the technical feasibility of combining multiple residential users at city level. The purpose of this work is to promote self-consumption and self-sufficiency from the network, using the integration of solar energy with PV-battery systems, and to reduce electrical losses in favor of both the single user and the distribution system. Results show that different values of self-sufficiency and self-consumption can be reached depending on the shape and dimension of each building. It was shown that it is possible to satisfy the current requirements to become an Energy Community in an urban environment with good levels of self-sufficiency.

Published: March 2021

Laser ablation is gaining acceptance as a cancer treatment technique because of its localized energy delivery to the tumorous tissue. The combination of laser ablation with nanoparticles allows for more precise targeting of the ablative area with less damage to adjacent healthy tissue. Nevertheless, heat damage to adjacent tissue is still a potential concern. Therefore, mathematical modeling of laser-tissue interactions is a necessary part of clinical treatment planning. In this study, the temperature distribution during laser-induced thermotherapy in cancer treatment investigates using a multilayered skin (epidermis, dermis, subcutaneous fat, and muscle) with an embedded tumor model. The effects of related parameters systematically investigate; wavelength, laser intensity, beam area, tumor absorption coefficient, tumor position, tumor blood perfusion rate, and irradiation time. Mathematical modeling in this study is solved by finite element method (FEM) via COMSOLTM Multiphysics Software. Laser absorption and thermal phenomena are described by Beer-Lambert’s law and Pennes’s bioheat equation.

Authors: Aabid Abdul , Khan Sher Afghan
Published: March 2021

This article focuses on the flow development and the static wall pressure distribution along the circular duct from the convergent-divergent (CD) nozzle. The study aims to examine the quality of the stream in the conduit when the control is employed. The microjets are activated at the base at (PCD) of 13 mm, and the diameter of the microjets is 1 mm. Mach numbers of the investigation are 1.3, 1.9, and 2.4. The length of the duct considered was from L = 10D to 1D. The diameter of the enlarged tube was 16 mm. The experiments were conducted for NPRs from 3 to 11. The results revealed that the lowest duct length mandatory for the flow continued to attach with the circular duct wall are L/D = 1, 2, and 3 for Mach numbers 1.3, 1.9, and 2.4, respectively. The investigation outcome indicates that there are mild oscillations in the flow-field for correctly expanded flows. The oscillatory trend has a pronounced impact on the duct's flow when the jets are operated at higher NPRs. The control does not adversely affect the flow field, and the magnitude of wall pressure is nearly similar.
Turbulence Modeling a Review for Different Used Methods
Authors: Hami Khelifa
Published: March 2021

This contribution represents a critical view of the advantages and limits of the set of mathematical models of the physical phenomena of turbulence. Turbulence models can be grouped into two categories, depending on how turbulent quantities are calculated: direct numerical simulations (DNS) and RANS (Reynolds Averaged Navier-Stokes Equations) models. The disadvantage of these models is that they require enormous computing power, inaccessible, especially for large and complicated geometries. For this reason, hybrid models (combinations between DNS and RANS methods) have been developed, for example, the LES (“Large Eddy Simulation”) or DES (“Detached Eddy Simulation”) models. They represent a compromise - are less precise than DNS, but more precise than RANS models. The results presented in this contribution will allow and facilitate future research in the field the choice of the model approach necessary for the case studies whatever their difficulty factor.

Authors: Rezende Tiari R. , Vianna Regina F. , Luporini Samuel
Published: March 2021

The use of nanofluids as coolant fluid in a plate heat exchanger (PHE) was investigated by conducting 3D CFD (Computational Fluid Dynamics) simulations. Al2O3/water nanofluid with volume concentrations of 2%, 3% and 4% was used as coolant fluid and water as hot fluid. In addition, the effects of corrugation angle of the plates were analyzed by varying them between 0° and 60°. Validation was performed by using heat transfer coefficients experimentally obtained in a previous study. Results show that the use of nanofluids in higher concentrations improves the performance of the PHE’s parameters. The angles of 30° and 60° between the plates reduce pressure drop and reflux regions improving the heat exchange. The variations of the nanofluid flow must take into account the proper pressure drop for the process where is PHE is employed because the increased flow rate results in a significant increase in the pressure drop. In general, this work has potential to be used for enhancing the design of PHEs.

Published: March 2021

The present study investigates numerically MHD flow near the stagnation point of micropolar fluid through a shrinking sheet containing nanoparticles under the influence of chemical reaction and external heat. The study is an attempt to investigate the flow behaviour of micropolar nanofluid because of its importance in heat transfer process in industries as well as cooling systems. The governing equations are converted to nonlinear ordinary differential equations by implementing similarity transformations. Numerical results are investigated in the form of figures and tables by using MATLAB built in solver bvp4c for various dimensionless parameters. The impacts of external heat parameter on temperature and chemical reaction factor on concentration of the nanofluid are illustrated in the form of graphs. It is observed that the temperature of the nanofluid and nanoparticle volume distributions increase when Biot number attain larger values. Rise in Thermophoretic parameter increases the nanoparticles concentration in the boundary layer. Numerical data are presented for Nusselt number and Sherwood number.

Published: March 2021

Biomass energy is one of the most important renewable energy sources. Full utilization of this energy helps to optimize agricultural development, improve our living environment, and replace some non-renewable energy sources, thereby promoting the eco-environment across the country. However, biomass energy has not been extensively utilized in rural areas of China. Many farmers are not very enthusiastic about the use of biomass energy. Many scholars have tried to boost the willingness of farmers to utilize biomass energy. Therefore, this paper collects the relevant data from six aspects, namely, environmental factor, cost factor, income factor, behavior factor, policy factor, and personal factor, and constructs a binary logistic regression model. On this basis, the driving and influencing factors of biomass energy utilization were empirically analyzed from the perspective of farmers. The results show that the development of biomass energy is mainly affected by the farmers’ awareness of national energy strategy, the relevant costs of biomass utilization, and the attitude of family members and village committee. The research provides an important reference for further promotion of biomass energy, elevation of its utilization efficiency, and optimization of energy structure in rural China.
„Odwrócony dekalog”, popękana kultura. Socjologiczne refleksje wokół kultury i religijności
Authors: Świątkiewicz Wojciech
Published: March 2021

Attitudes towards the Ten Commandments, expressed in accepting or rejecting its principles, mark the direction of changes in Christian civilization and culture. The results of nationwide sociological empirical research conducted among university students in 2017 were a premise for the conclusions on the deconstruction of the Decalogue, which is subject to relativization procedures and inscribed in the cultural spaces of transition from objective morality to subjective morality, from the morality of orders and prohibitions to the morality of free choices justified by the principle of situational conformism. Attitudes towards the Decalogue are not only a consequence of selective choices and rejections but also of subjective composing and free structuring of decalogical principles. The in-verted decalogue shows the broken foundations of Christian civilization and the lost experience of cultural identity expressed in the formula etsi Deus non daretur. The article consists of six points: Introduction: Culture and Religion, The Role of Religion in the Processes of Cultural Legitimation, The Decalogue in the Christian Tradition and its Role in Culture, Accepted and Rejected The Decalogue, The Decalogue of Deeply Believers and Systematic Practitioners, Conclusions.
Problemy użycia języka religijnego we współczesnych mediach
Authors: Kindziuk Milena
Published: March 2021

In discussions about religious discourse in the media, the tension or discrepancy between the communicative secular and secularized language of contemporary media and the more hermetic and traditional language describing situations related to religious experience, i.e. the sacred is emphasized. This article is an attempt to answer the question of what the religious language of the media should be. The research problem is: is it to be adapted to the contemporary Polish language, taking into account the commonplace, or more archaic, theological, referring to biblical and cultural codes? When discussing the ways of transmitting religious content in the media, two elements should be taken into account: 1) religious language has always been and is the language of communication (proclamation), focused on lively contact with the recipient and caring for communication; to some extent always adapted to the recipient; contemporary media, which are rapidly developing themselves, speed up this adaptation process, but this process is part of the nature of the language; 2) the creators or the first teachers of great religions (excluding small esoteric religions) used spoken language, close to colloquial language, understandable, adapted to the audience (their teaching or revelation was written later); they, too, are a model of inculturation that religious language continues to undergo, without giving up their specificity and sacredness. It should be mentioned that the research questions posed in this article concern only the religious language of media messages, not the language of official religious communication. This article uses the research method based on a critical analysis of the scientific discourse on religious language in the media studies literature from 1998-2020, combined with the presentation of own proposals in this area.

Authors: SARI Ramazan , BULDANLI Mehmet Zeki
Published: March 2021

Amaç: Hematolojik malignitelerde sistemik tutulum nedeniyle cerrahinin faydası oldukça sınırlıdır. Splenektomi özellikle izole dalak lenfomalarında kimi zaman hem tanı hem de tedavi amaçlı gerekir. Bu çalışmanın amacı lenfoma tanısıyla takip edilen hastalarda splenektominin endikasyon ve yararlarını incelemek, operasyon sonrasındaki klinik sonuçlarımızı tartışmaktır.

Gereç ve Yöntemler: Çalışmamıza Ocak 2012 ve Aralık 2019 tarihleri arasında lenfoid malignite nedeniyle hematoloji bölümünce takip edilen ve splenektomi endikasyonuyla tarafımıza yönlendirilen hastalar dahil edildi. Hastalara ait demografik ve klinik veriler ile tedavi sonuçları geriye dönük olarak incelendi.

Bulgular: Çalışmaya toplam 44 hasta dahil edildi. Hastaların splenektomi zamanındaki yaş ortalaması 58,2 (±12.4) idi. Hastaların %63,6’sı erkekti. Splenektomi sonrası ortalama takip süresi 12,3 (3-94) aydı. 26 hasta semptomatik splenomegali, 18 hasta medikal tedaviyle düzeltilemeyen trombositopeni ve anemi gibi endikasyonlarla opere edildi. Tedavi sonrası klinik iyileşme splenik marjinal zon lenfomasında diğer lenfoma tiplerine göre daha yüksekti.

Sonuç: Son yıllarda özellikle monoklonal antikorlarla yapılan medikal tedaviler sayesinde lenfoma tedavisinde cerrahi ihtiyacı giderek azalmaktadır. Verilerimiz dalak tutulumu olan lenfoid malignitelerde ve özellikle splenik marjinal zon lenfomasında splenektominin etkili ve güvenli bir tedavi seçeneği olduğunu göstermektedir.
