Authors: Kulkarni Akshay B. , Mathad Shridhar N. , Bakale Raghavendra P. 
Published: June 2019

Abstract
This work had the objective to analyze the thermodynamic properties of cadmium doped cobalt zinc ferrite (Co0.5Zn0.5Cd0.3Fe1.8O4), obtained by solid state reaction method and characterized by TGA-DTA. The TG analysis show sharp peaks at four points, two for water reduction, one for decomposition of chlorides and last one for formation of end product. The ratio of weight of end product to starting material match with ratio of molecular weight of end product and starting materials; this confirms the formation of ferrite sample. Broido, Coats-Redfern, Chang and Horowitz-Metzger approximations are employed to compute the activation energy (E
a) of formation of ferrite sample. The kinetic parameters like frequency factor (A), entropy change (ΔS), enthalpy change (ΔH) and changes in internal energy (ΔG) of sample are also reported.

Abstract
This study examined the perceptions of able-bodied beggars to factors responsible for their prevalence and the land uses they occupied for their activities in Ibadan metropolis. Nigeria. Data were obtained from 117 (18, 12, 46, 13 and 28 in the areas of Sango, Iwo Road, Sabo, Challenge and Oja Oba, respectively) randomly selected able-bodied beggars using a structured questionnaire. The data were analyzed using percentages, mean index, standard deviation, chi-square and Analysis of Variance (ANOVA). The study showed that 51.3% of the beggars were males; the youngest was 19 years old, while the oldest was 59 years. The average age of the beggars was 33 years. Further findings revealed that the average household size for the study area was 5, while the standard deviation was 2.6. The important perceived factors responsible for the prevalence of begging among the able-bodied beggars, measured on a 5-point Likert Scale, were homelessness (4.29), lack of skills for gainful employment (3.77), debt (3.64), meeting cost of education/children’s education (3.64), inability to secure a job (3.52) and lack of food (2.97). The study further revealed that the prevalence of begging among able-bodied beggars varied with land uses. Against this background, it was concluded that the information obtained on the socio-economic attributes of able-bodied beggars, perceived determinants of their prevalence and their targeted land uses could be utilized by policy-makers and urban planners to proffer lasting solutions to the menace of begging.
Preliminary reflectivity analysis of severe convective events in in the proximity of Goczałkowice-Zdrój, Poland
Authors: Pilorz Wojciech , Ciaramella Philip 
Published: June 2019

Abstract
At the beginning of 2018, the X-band radar in Goczałkowice-Zdrój (southern Poland) was launched. The scanning area corresponds with the scanning area of the POLRAD C-band radar system operated by the Polish Institute of Meteorology and Water Management. New opportunities were created for imaging phenomena by comparing some reflectivity features from C-Band radar and X-Band local weather radar. Moreover, some of the signatures located in the lower troposphere can be better documented by local X-Band radar. Firstly, reports from the ESWD (European Severe Weather Database) have been thoroughly analysed. All severe weather reports in the proximity of Goczałkowice-Zdrój (100-km radius) were gathered into one-storm events. Then the reflectivity from both radars was analysed to determine which reflectivity patterns occurred and when. X-band radars are known from the more intensive attenuation of the radar beam by the scatterers located closer to the radar, thus it is essential to compare capabilities of these two different radar systems. It was found that the average reflectivity for all convective incidents is higher when using POLRAD C-band radar data. In some events it was possible to find some spatial reflectivity signatures. We also discuss other reflectivity signatures previously described in the literature. Taking into account stronger Goczałkowice-Zdrój X-band radar attenuation, we suggest that some of these should be reviewed by reduction of the reflectivity thresholds.
Impact of globalization on the handloom industry – A case study of the Hugli district of West Bengal
Authors: Sarkar Sharmistha , Mukhopadhyay Sayani 
Published: June 2019

Abstract
The concept of globalization appeared in the Indian subcontinent in 1991. With the onset of liberalization, privatization and globalization a new chapter has been opened up in the Indian economy and her billion plus population. The Hugli district is one of the most renowned names in the handloom industry of West Bengal and a good percentage of people are engaged in this heritage industry. The study is conducted in five handloom clusters of the district, namely – Dhaniakhali - Somaspur, Begumpur, Haripal, Rajbolhat and Balagar. The main objectives of this paper were to investigate the effects of globalization on the rural handloom weaver community, in terms of their economic and social conditions. At the same time the article intends to analyse the changes in the over all production scenario of the handloom industry in the district due to modernization. It can be said that the handloom industry of the Hugli district is suffering from some inherent problems like low productivity, lack of product diversification and problems related to procuring raw materials. The co-operative sectors are indifferent to enlarging their market sphere. Though there are plenty of efficient and skilled weavers but they are only doing their traditional practices, the adoption of modern techniques is significantly poor among the weavers. Therefore the new generations are totally unwilling to accept weaving as their main occupation because of the uncertainty of the industry. The article also suggests some strategies to make this ever challenging industry globally competitive, such as, the identification of modern trends, promotion of exports, market assessment so that this heritage industry can cope with the modern trends and utilise the benefits of globalization.

Abstract
The paper is focused on Family Policy of rural municipalities. National strategic documents, documents intended for implementation of Family Policy at regional and local levels and local plans/conceptions for Family Policy within municipalities of up to 5,000 inhabitants are analysed. Special attention is paid to the competition: “Family-friendly Community”. Results of the analysis show that this competition does not fulfil its mission, despite the favourable environment for Family Policy within rural municipalities. The results of the study in accordance with generally prevailing opinion show, that it is not efficient to elaborate conceptions of Family Policy within such small municipalities.
Tackling the Problem of Class Imbalance in Multi-class Sentiment Classification: An Experimental Study
Authors: Lango Mateusz 
Published: June 2019

Abstract
Sentiment classification is an important task which gained extensive attention both in academia and in industry. Many issues related to this task such as handling of negation or of sarcastic utterances were analyzed and accordingly addressed in previous works. However, the issue of class imbalance which often compromises the prediction capabilities of learning algorithms was scarcely studied. In this work, we aim to bridge the gap between imbalanced learning and sentiment analysis. An experimental study including twelve imbalanced learning preprocessing methods, four feature representations, and a dozen of datasets, is carried out in order to analyze the usefulness of imbalanced learning methods for sentiment classification. Moreover, the data difficulty factors — commonly studied in imbalanced learning — are investigated on sentiment corpora to evaluate the impact of class imbalance.
Extensible Implementation of Reliable Pixel Art Interpolation
Authors: Stasik Paweł M. , Balcerek Julian 
Published: June 2019

Abstract
Pixel art is aesthetics that emulates the graphical style of old computer systems. Graphics created with this style needs to be scaled up for presentation on modern displays. The authors proposed two new modifications of image scaling for this purpose: a proximity-based coefficient correction and a transition area restriction. Moreover a new interpolation kernel has been introduced. The presented approaches are aimed at reliable and flexible bitmap scaling while overcoming limitations of existing methods. The new techniques were introduced in an extensible. NET application that serves as both an executable program and a library. The project is designed for prototyping and testing interpolation operations and can be easily expanded with new functionality by adding it to the code or by using the provided interface.

Published: June 2019

Abstract
Background: Pre-eclampsia (PE) affects 2% to 5% of all pregnancies and is a major cause of maternal and perinatal morbidity and mortality worldwide. Since PE has complex pathogenesis and treatment is still not found, effective methods for prediction and prevention of PE are still actively searched.
Aim: The aim of this study was to find the mean maternal serum concentration of four proteins in Bulgarian pregnant women and to investigate the correlation with uterine artery pulsatility index in the first and second trimester of pregnancy.
Materials and methods: In this prospective case-control study, maternal serum concentrations of corin, sEndoglin, PP13, and sFlt-1 were measured, pulsatility index of uterine artery (PI-UA) was assessed in 40 women with Doppler, twice during pregnancy – at the 11th – 13th weeks of gestation and the 20th gestational week. They were randomized in two groups: an experimental group: with increased PIUA at gestational week 13 and a control group: with normal PI-UA. All pregnancies were followed up until the day of delivery and outcomes were recorded.
Results: There was no significant difference in the APGAR score and birth weight of the newborns between groups. We found no significant difference in the mean concentration of sEnd, sFlt-1 and PP13 between 11-13 weeks of gestation and 20 week of gestation in the control and experimental groups. Statistically significant difference was found only in the mean concentrations of corin between weeks 11-13 and week 20 in both control (t=3.27; p=0.004) and experimental group (t=3.22; p=0.005). Corin levels and the mean PI of uterine arteries tended to decrease with progression of pregnancy in both groups.
Conclusions: Further prospective studies of larger populations are required to develop a panel of multiple predictors for PE.

Published: June 2019

Abstract
Background: Despite the use of traditional method, Ugi reaction currently is a well-established multicomponent reaction. Chromane motif itself possesses a variety of biological functions. In order to improve its anti-tubercular activity, it is necessary to modify it accordingly.
Aim: To ensure relation between in silico and in vitro study, we have carried out in vitro screening against H37Rv anti-tubercular agent.
Materials and methods: Ugi four-component condensation (U-4CCRs) between 6-fluorochroman-2-carboxylic acid, various aryl aldehyde, 3,4,5-trimethoxy amine and tert-butyl isocyanide, gave N-((tert-butylcarbamoyl)(4-substitutedphenyl) methyl)-6-fluoro-N-(3,4,5-trimethoxyphenyl) chroman-2-carboxamide. The molecular level insight of all compounds was carried out by molecular docking study against the receptor tyrosine phosphatase PtpB. All these newly synthesized compounds were screened for their anti-microbial activity against Mycobacterium tuberculosis H37Rv to determine the MIC, IC50 and IC90 of the compound.
Results: The compound 5d also shows large hydrophobic surface contact on the face of the α7–α8 (Ile 207, Phe 211, Met 206, Ile203, Phe161, Phe80, Met126, Tyr130, Val231 and Leu101) that lines one side of the entrance to the active site of the receptor. The compound 5d bind with tyrosine phosphatase PtpB with predicted docking geometric score of 4664, whereas a score of rifampicin was 6586 determined.
Conclusion: From the docking studies, compound 5d, was considered to be the potent inhibitor, which gave strong supportive coordinate with the in vitro study. It is highly active against H37Rv, having MIC and IC50 value of was 70 μM and 53 μM respectively in in vitro study.

Authors: Mitova Nadezhda G. , Rashkova Maya R. , Popova Hristina L. , Kozarov Anton S. 
Published: June 2019

Abstract
Background: Periodontal pathology in children has distinctive characteristics that can be accounted for by the peculiarities of the age, the dynamically changing oral environment, and the processes of formation and stabilization of periodontal structures during teeth eruption.
Aim: The aim of this study was to investigate the composition of the subgingival microbiota during permanent dentition formation in puberty.
Materials and methods: The study included 30 children aged between 10 and 15 years without gingivitis (up to 25% PBI), with good oral hygiene, with no systemic diseases or reception of antibiotics for 3 months. The clinical status of all children was assessed using a specially designed chart based on the periodontal examination chart of a child adopted by the Department of Pediatric Dentistry, FDM-Sofia. Gingival sulcus samples were taken with a paper pin from 6 teeth for a PCR – Real Time study of 9 control strains (a comprehensive sample). The samples were sent for investigation in standardized containers.
Results: C. gingivalis (green complex) was found in almost all tested children and F. nucleatum (orange complex) - in more than half of them. The rest of the tested samples for microorganisms was isolated in just few of the children (6% - 17%). A. actinomycetemcomitans and P. gingivalis were not isolated in this study.
Conclusion: The results of the study suggest that a significant amount of the periodontal pathogens migrate to the subgingival zone relatively early, immediately after the permanent teeth eruption, and become a risk factor for the development of periodontal disease.

Published: June 2019

Abstract
Giant cell tumor of bone is a histologically benign but locally aggressive osteolytic lesion, capable of spreading ‘benign’ metastases mainly to the lungs. Since its description as a separate entity, surgery has been the mainstay of treatment. Recently, target therapy has been introduced using denosumab – an inhibitor antibody for the receptor activator of nuclear factor kappa B ligand with dramatic eff ect on the natural course of the tumor. Herein, we report a rare case of an aggressive stage 3 giant cell tumor of bone of the proximal fibula that was successfully downstaged using neoadjuvant denosumab treatment and then treated by surgical excision followed by adjuvant target therapy. The clinical characteristics and treatment modalities of giant cell tumor of bone, the indications for target therapy, therapy response, and histological changes are also briefly discussed.

Italy-Azerbaijan relations: an analysis by means of social networks
Authors: Bernardini Enrico 
Published: June 2019

Abstract
The European focus on the Caucasus region has increased considerably and reflects the need for safe access to the various energy resources in the Caspian region.
In this sense, Azerbaijan plays a key political role because of its geographical location, as a privileged bridge for trade between East and West, but also for historical and cultural reasons, placed between Russia, Iran and Turkey, interlocutors with whom, especially today, it is necessary to confront.
The contribution aims to focus on the Italy-Azerbaijan relationship through the eyes of social networks, analyzing first how well they are known in the country of Central Asia and then which are those most used by the population. Secondly, the country’s data will be related to the global trend to highlight similarities and differences. Finally, it will be analyzed the pages and groups of social networks that deal with the relationship between Azerbaijan and Italy, showing the main topics covered and how the two countries are getting closer not only for economic reasons, but also cultural because in Azerbaijan the Italian culture is known and appreciated, especially the language, music, art and gastronomy.

Published: June 2019

Abstract
In today’s socio-cultural context, the period of youth is less experienced as a predictable path towards the assumption of the adult status and increasingly characterised by the difficulty of defining one’s identity, prefiguring one’s future paths and choices to make. To these problems, one must add the so-called collateral damages produced by the Web, which condition, or can condition, the configuration of the personalities of young people, the shape and quality of their relationships, the sense of events, their experiences and how values and faith are conceived.
The Mediterranean Region: between terrorism, tourism and security
Authors: Varani Nicoletta , Bernardini Enrico 
Published: June 2019

Abstract
Tourism remains a very vulnerable sector and sensitive to both internal and external impacts, such as economic and social crises, natural disasters, epidemics and diseases, national and international conflicts. Among these, the most alarming threat in the 21st century remains terrorism. In this sense, this paper aims to study the effects of the increasingly frequent terrorist attacks by the extremist factions of Al-Qaeda and ISIL on the tourism industry in the Mediterranean Region. The contribution, after having discussed in general the tourism market in the Mediterranean Region, intends to highlight the impacts and repercussions of the terrorist attacks on tourism, presenting the example of Egypt and one of its best-known tourist destinations, Sharm el-Sheikh. In this sense, it is shown how, in a few years, the political instability of the country and the attacks of 2005 and 2016 have significantly reduced the influx of tourists, transforming it from one of the most visited destinations in the world in a place of increasing abandonment.
