Authors: Mizan Md Mizanuzzaman 
Published: June 2021

From the beginning of IC engine era, it is trying to improve the performance and efficiency of internal combustion engine. In this study, numerically analysis on combustion of Propane, Propanol and Octane in SI engine have been done thoroughly and presented to assess the potentiality and highlighted the comparison. For this analysis thermodynamic engine cycle model is developed for numerical analysis. Mathematical models considering fundamental equation and empirical relation are implemented in a single cylinder 4 stroke spark ignition engine (system) with the help of FORTRAN 95 to find out heat losses, friction losses, output parameter etc. Single cylinder four-stroke spark-ignition (SI) engine is considered as system. In this study, different working parameters like 8 and 12 compression ratios with three different rpm 2000, 4000 & 6000 are considered for simulation. This study shows the different comparisons of energy-exergy content (%), as example of exhaust gas 35.08 & 17.82, 37.02 & 19.22, 37.79 & 19.79 for Octane (at compression ratio 8 and 2000, 4000, 6000 rpm) etc., which explains the potentiality content and the potentiality losses in different process like combustion, mixing of gases etc. It also shows for the fuel propane and propanol in similar way with changing different operating conditions. Maximum inside cylinder temperature, 1st law and 2nd law efficiencies were determined for the fuels with respect to different compression ratio and engine speed.

Published: June 2021

Ecosystem service and disservice components have a great impact on the environment as well as on urban life. The aim of the research is to assess the impact of ecosystem services and disservices by tracking the change over a span of 15 years (2005-2020) using satellite image analysis. It was conducted in wards 23 and 29 of Khulna City Corporation (KCC), an area adjacent to the river. The overall work breakdown has been rounded up in a methodological framework which cleaved into two parts focusing on ecosystem services, disservices and multispectral image analysis steps. Multispectral image analysis has been done using Normalized Difference Vegetation Index (NDVI) and Normalized Difference Build-up Index (NDBI). On the other hand, geospatial analysis has been done using Digital Elevation Model (DEM), Service Area Analysis (SAV) and other mapping tool including Geographic Information System (GIS) to show the changed impact of both ecosystem components. The study areas attain provisioning, habitat, cultural and regulatory service components and the disservice elements have been sorted out according to sources. Comparative study showed increase in the buildup area; vegetation coverage because of increasing vegetation, cultivation and gardening practices; good weather and water circulation condition and water body conservation which has significant positive impact on the area. The disservice component like poor drainage condition and solid waste management system and risky infrastructures have negative impact, need to address for the betterment of residence and environment.
‘I Wouldn’t Call the Cops if I was Being Bashed to Death’: Sex Work, Whore Stigma and the Criminal Legal System
Authors: Stardust Zahra , Treloar Carla , Cama Elena , Kim Jules 
Published: June 2021

Discourse on sex work is replete with narratives of risk and danger, predominantly focused on violence and disease. However, the risks instigated by police, maintained by the criminal justice system and sanctioned by the state—criminal laws, licensing laws and targeted policing—receive far less attention. This paper responds to this gap in three ways. First, we examine how stigma manifests in sex workers’ experiences of Australian policing, which act to disincentivise sex workers from accessing criminal legal mechanisms. Second, we illustrate how sex workers are denied victim status as they are seen by law as ‘irresponsible citizens’ and blamed for their experiences of crime. Third, we argue that these factors create conditions in which sex workers must constantly assess risks to access safety and legal redress while structural sex work stigma persists unabated. We conclude that ‘whore stigma’ is entrenched in the criminal legal system and requires a systematic response that necessitates but goes beyond the decriminalisation of sex work.

Authors: Abdikarimova A. T. , Aimagambetova G. B. 
Published: June 2021

The fundamental structural transformations that have taken place in the country's economy have led to a deterioration in the quality of the economic system and increased dependence of the national economy on the conjuncture of world markets. Our previous research was concerned with determining what triggered the change in the structure of the economy, how effective the changes were, and what changes in sector proportions they led to. In this article, we tried to analyze whether we are facing the consequences of the "Dutch disease", which led to structural transformations in the economy.The purpose of the study is to confirm our assumption that the economy of the Republic of Kazakhstan is subject to the "Dutch disease".Methodology of the study. The authors relied on the cointegration analysis of time series using the Engle-Granger tests, the analysis of the stationarity of the Dickey-Fuller methods in order to determine cointegration, to assess the degree of interrelation between the values of mining and manufacturing production volumes on GDP indicators, as evidence of the presence of "Dutch disease".Originality / value of the research. The originality and value of the study lies on the fact that the authors tried to analyze the economy for the presence of "Dutch disease" in the economy of Kazakhstan using time series analysis methods.Findings. There is an assumption that the economy of Kazakhstan has certain symptoms and signs of the "Dutch disease", but it is not possible to say unequivocally that it was the main catalyst for structural changes, due to the fact that we could not prove the existence of a negative relationship between the growth rates of the mining industry and the manufacturing industry.

Estrabón y el clasicismo
Authors: Naranjo Rafael 
Published: June 2021

Although different scholars have noticed the adscription of the geographer Strabo to the artistic and ideological movements of atticism and classicism, we offer a more deeper analysis of this issue, with special attention to some points that, according to us, have not been examined enough, like the relation of classicism with the fact that Strabo adopted Polybius as his direct predecessor, his positive vision of Homer or the constant references to Isocrates’ pedagogical and panhellenic ideas. We provide numerous details that, according to us, prove these facts throughout his geographical work.
Women in Herodotus’ Oracles. A Look beyond the Pythia
Authors: Sánchez-Mañas Carmen 
Published: June 2021

Women other than the Pythia are excluded from the consultation and reception of oracles, but they are nevertheless present in the oracular passages of Herodotus’ Histories. This paper focuses on the roles that they play in these passages, with the aim of determining the extent of their visibility. To this end, an analysis is conducted on the basis of their belonging or non-belonging to the community of male consultants or recipients of oracles. The examination shows that female presence in Herodotean oracular passages is quantitatively significant, diverse and pivotal in revealing interactions between the domestic and public domains within the communities involved in these passages.
