Authors: Belli-Carhuayo Félix Ricardo , De la Torre-Castro Rene Anselmo , Argota-Pérez George 
Published: July 2023

El objetivo del estudio fue describir el costo ambiental del coeficiente de transformación biodegradable en efluentes de las lagunas de oxidación, Ica, Perú. En enero y febrero de 2023 se muestreó los efluentes de las lagunas de oxidación de Angostura Limón, Yaurilla y Pueblo Nuevo. Se determinó la demanda bioquímica de oxígeno (DBO5,20) y la demanda química de oxígeno (DQO) donde las concentraciones se compararon con el límite máximo permisible del Decreto Supremo 004-2017 MINAM - Perú. Con los datos se estimó el costo ambiental mediante un cociente entre el costo de evaluación (COA) y el costo de prevención normativo (CONP). Los valores fueron: DBO5,20 = 203,1 mg.L-1 y DQO = 405,0 (Angostura Limón), DBO5,20 = 273,1 mg.L-1 y DQO = 450,8 mg.L-1 (Yaurilla) y DBO5,20 = 366,5 mg.L-1 y DQO = 628,0 mg.L-1 (Pueblo Nuevo). El costo ambiental fue igual a 0. Los valores de la DBO5,20 y DQO superaron el límite permisible normativo: 5,0 mg.L-1 (DBO5,20) y 20,0 mg.L-1 (DQO) por cuanto, existió alto contenido de materia orgánica que no se biodegradó, antes las concentraciones parciales de oxígeno. Los efluentes se muestran como recurso de valor limitante. Se concluye, que las concentraciones de la DBO5,20 indicaron que hubo biodegradabilidad en las lagunas de oxidación, pero el contenido de materia orgánica es elevado donde el tiempo de retención para su degradación resulta insuficiente y esta dinámica influye en la limitación de uso de los efluentes porque su tratamiento no fue adecuado.

This article discusses the main issues related to the impact of tourism on the regional economy, and also proposes a number of measures to reform the management of tourism activities at the regional level.
TRANSFORMATION OF THE EU COUNTRIES TO THE CIRCULAR ECONOMY MODEL
Authors: Roleders Viktoriia 
Published: July 2023

The article is devoted to the research of the transformation of the EU countries to the circular economy model.
The concept of the circular economy is based on the approach of closing the production cycle, the extended duration of the exploitation phase of the product life cycle, and the processing of waste as resources subject to secondary use. The circular economy is based on a completely new paradigm, according to which it is necessary to analyze in detail existing economic systems and reorganize them in order to increase the level of efficiency in the use of natural resources, transform waste into resources and introduce a new approach to production and consumption.
National circular economy monitoring indicators are adapted to strategies, policies and actions specific to a particular country. This is an obstacle to make comparison between countries. There is no single specific, universally accepted set of indicators or indicators that would measure progress in implementing a circular economy for countries.
In order to assess the progress of the countries of the European Union, Great Britain, Norway and Ukraine regarding the implementation of the circular economy, an analysis of 13 indicators, grouped into 4 categories, was carried out, which formed the basis of the creation of the circular economy achievement indicator.
A correlation analysis was conducted between the calculated circular economy indicator and the global competitiveness index and a positive correlation (0.665) was obtained. Germany, the United Kingdom, the Netherlands, and Austria were found to be leaders, while Ukraine, Bulgaria, Cyprus, Greece, and Malta were outsiders in the circular economy index and global competitiveness index. Germany, Great Britain, the Netherlands and Austria belong to the group of leaders regarding the implementation of the circular economy and the level of competitiveness.
It was proved that integral indices, used in the decision-making process at all levels, can become an important tool for improving the management of the socio-economic development of Ukraine, including the regional context. Their use will help to increase the ratings, prestige and authority of the country on the world stage.
ALTIN ORDA HANLIĞI’NDA HAREZM’İN YERİ
Authors: DERİN PAŞAOĞLU Derya 
Published: July 2023

Cengiz Han’ın Harezm seferiyle Moğol hâkimiyeti altına alınan Harezm, toprak taksimatında büyük oğlu Cuçi’ye bırakılmıştır. İpek Yolu ticaretinde doğu ile batının buluşma noktalarından bir olan Harezm, Moğol hâkimiyeti öncesi ehemmiyetini sonrasında da muhafaza etmiştir. Cuçi’nin ölümünden sonra oğlu Batu Han’ın liderliğinde (Ak Orda hanedanı olarak) Deşt-i Kıpçak coğrafyasında Cuçioğulları, Altın Orda Hanlığı’nı tesis etmişlerdir. 1379’da Emir Timur’un hâkimiyetine geçinceye kadar Altın Orda Hanlığı’nın bir parçası olan Harezm, siyasi, askeri, ekonomik ve kültürel birikimini Altın Orda coğrafyasına aktarmıştır.
Harezm’in idaresi, Altın Orda Hanlığı’nın nüfuzlu kabilelerinden Kongratların bırakılmış ve Emir Timur’un Harezm üzerinde yürüttüğü hâkimiyet mücadelesi sürecine Kongratların Altın Orda’ya sadakati devam etmiştir. Bozkır aristokrasisinin etkin rol oynadığı Altın Orda Hanlığı’nda Saray’ın aristokrat yapı üzerindeki otoritesi zayıflayınca güçlü liderler han soyundan şehzadeleri destekleyerek taht üzerindeki nüfuzlarını artırmaktadırlar. Bu süreçlerde muhaliflerin güçlenmek için çekildikleri, kazak çıktıkları, iki bölge ön plana çıkar, bunlar; Kırım ve Harezm’dir.
Kırım ve Harezm’in siyasi hamlelerde ön plana çıkmasını her ikisinin de sahip olduğu ekonomik potansiyelde aramak gerekir. Zira her ikisi de İpek Yolunda önemli durak noktalarıdır. Ekonomik güçleri oranında bu bölgede bulunanların sahip olacakları askeri dolayısıyla da siyasi güçleri artacaktır. Harezm bölgesi sadece ekonomik değil, kültürel birikimiyle de Altın Orda coğrafyasını ve Saray’ı beslemiştir. Mimaride, çinicilikte ve dil ve edebiyatta Harezm kültürünün etkisi Saray ve çevresinde verilen eserlerde ayırd edici şekilde gözlemlenebilmektedir.

The Qur'an is a source of excavation and development of Islamic teachings in various dimensions of human life. This paper tries to develop economic studies from an economic point of view based on the interpretation of the Qur'an. As a methodology, tafsir plays an important role in order to develop the discipline of Islamic economics. The model of economic interpretation derived from the thematic interpretation of the Qur'an is developed through four phases including; Classification of Qur'anic verses related to economics, understanding them based on chronology, micro and macro context, and socioeconomic contextualization. In summary, this paper reveals that consumption behavior in the Qur'an is harmoniously regulated, gradual and systematically to propose a new model of consumption for Muslims through Islamic consumption behavior.

Quaternionic Bekenstein-Sanders Guage Fields for TeVeS
Authors: Horwitz Lawrence 
Published: July 2023

Treating the Bekenstein-Sanders field \(B_\mu\), for which \(B_\mu B^\mu = -1\) as a gauge field requires that the field be non--Abelian. This structure was worked out in a previous publication by Horwitz, Gershon and Schiffer, where an equivalent Kaluza-Klein metric was found for an extended (\(5D\)) spacetime. In this paper, we study a quaternionic formulation of this theory with quaternionic gauge fields and quaternionic wave functions (as discussed in two seminal books by S.L. Adler), thereby establishing a connection between quaternionic quantum mechanics and general relativity.
Can electromagnetic fields form tensors in a polarizable medium?
Authors: Franklin Jerrold 
Published: July 2023

One of the bases of relativistic electromagnetism is that the electromagnetic fields \(\bf E\) and \(\bf B\) are components of an electromagnetic field tensor \(F^{\mu\nu}\). There is a simple proof of this in the absence of a polarizable medium. It has sometimes been assumed that the fields, \(\bf E\) and \(\bf B\), and their associated fields, \(\bf D\) and \(\bf H\), are also components of tensors in a linearly polarizable medium. In this paper, we question that assumption, and show that a proof that they are components of a tensor fails. Consequently, the fields \(\bf E\), \(\bf B\), \(\bf D\) and \(\bf H\) are not components of a relativistic tensor in a polarizable medium.

The goal of this research is to produce liquid soap that preparations with four formulas by varying the methanol extract of sambang darah leaves as the active ingredient, characterizing, and understanding its antibacterial activity. Organoleptic tests, foam stability, pH, specific gravity, and viscosity were all used to characterize liquid soap. The best results were obtained with liquid soap formulation 3 (3 g extract), which had foam stability of 84.10%, a pH of 9.62, specific gravity of 1.03 g/mL, and viscosity of 492.933 cP. The organoleptic test revealed that the liquid soap was a homogeneous viscous liquid with a blackish-brown color and a characteristic extract odor. The inhibition zone for antibacterial activity against Staphylococcus aureus and Escherichia coli was 9.15 mm and 13.72 mm, respectively. In antiseptic tests, all soap formulas reduced bacteria on the thumb.
