Radiodynamic Therapy with Photosensitizers: Mini-Review of Experimental and Clinical Studies
Authors: Tzerkovsky D.A. , Mazurenko A.N. , Borychevsky F.F. , Shashkouski D.V.
Published: December 2022

Photodynamic Therapy (PDT) is a light-based method that uses photo-reactive molecules, such as different types of photosensitizers (PS), to destroy malignant tumors. As some authors testify, PS was shown to act as a radio-reactive molecule by enhancing generation of reactive oxygen species upon X-ray irradiation. The method of treatment, which is based on the combined use of PS and ionizing radiation, is called «Radiodynamic therapy» (RDT). The advantage of RDT over PDT is the X-ray’s penetrability through tissues, which will find many applications for treatment of deep malignant tumors. The authors of a number of research centers in Japan, Germany, Israel and Lithuania presented the experience of using RDT in experiments on tumor cell lines and animals with transplanted tumors. A clinical approbation of the method has been started in patients with unresectable forms of bladder and cervical cancer, with gliomas and other forms of malignant tumors. The data obtained in experiments on cultures of tumor cells and animals with transplanted tumors indicate a high antitumor efficacy of the RDT with various types of PS. This fact is confirmed by a statistically significant decrease in viable tumor cells with the combined use of RT and PS, as well as a pronounced inhibition of the growth of transplanted tumors compared with the control groups, including the group of radiation therapy in mono mode. The preliminary data obtained show good tolerability of the method in clinical oncology (no serious adverse reactions) and satisfactory antitumor efficacy (an increase in the frequency of objective responses and an increase in the % reduction in tumor volume, which made it possible to transfer them to a resectable state).
Mining industry in a border region of Russia: assessment of the potential industrial development in the Republic of Tyva
Authors: Oorzhak V.O.
Published: December 2022

In connection with the re-orientation of Russia's economic policy towards the East, an assessment of the potential for industrial development in such mining frontier territories of the country as the Tyva Republic becomes a major priority. For this purpose, the available academic literature as well as the results of scientific research have been analyzed. This study is also based on the data from official statistical sources, information obtained from the industrial companies in the region and the Internet resources. The analysis and synthesis methods used allowed to identify the main reasons for this lag, including the shortcomings of the current regulatory legislation. The gross regional product in the Republic of Tuva is only 243.05 thousand rubles per capita (vs. 645.9 thousand rubles in Russia and 535.3 thousand rubles in the Siberian Federal District). The paper proposes a hypothesis that a selective approach is required in regulating the economy of the country's depressed border territories with account of the characteristics, resources and potential of each of them. Empirical studies of the possibilities for industrial development of the one of the most depressed mining regions of Russia, i.e. the Tyva Republic, have been performed for the first time in the cross-border aspect with account of developing the available rich natural and mineral resources. An assessment of its potential, which is capable of achieving the industrial production volume of 350 billion rubles by 2035, has been made using linear regression methods. Measures have been proposed on creation of the legislative and legal regimes needed to attract investments in the development of the mining industry of Tuva, which can become a driving force of its dynamic social and economic development.

Government of Tuva adopted a resolution "On the Strategy of socio-economic development of the Republic of Tuva until 2030" (hereinafter referred to as the Strategy), which considers two scenarios for the long-term development of the republic: basic and target. When implementing the basic scenario, the established trend of development of the republic remains, in which the basic social guarantees for the population will be preserved, but at the same time the possibility of implementing large investment and infrastructure projects in the economy is excluded. When implementing the target development scenario, a radical change in the current structure of the economy and infrastructure is expected: the planned construction of the railway along the Kuragino-Kyzyl highway will be continued to Erdenet (Mongolia), which will become through, since it will be included in the trans-Mongolian railway. We have made an assessment of the scenarios of socio-economic development of Tuva using the input-output method. The assessment shows that the projected target indicators, both for the basic and target scenario of the development of the Tuva economy, differ somewhat from the indicators specified in the Strategy. We have assessed additional development factors, such as the growth of mineral extraction in connection with the implementation of the railway construction project to Mongolia, as well as taking into account the growth of GVA in transport and energy. Thus, it can be noted that the intersectoral balance is one of the optimal tools for analyzing and forecasting the economy of regions.

The paper demonstrates the need to develop methods of managing poorly caving roofs in the stoping and development faces as well as the ways of intensifying the degassing process of unrelieved coal seams to improve the technical and economic performance and safety of operation. Methods of the directional hydraulic fracturing (DHF) of the roof and the interval hydraulic fracturing (IHF) of the coal seam are suggested to eliminate the dynamic phenomena in coal mines as well as technological charts of their implementation. The DHF method consists in creating an initiating slot in the borehole walls, which acts as a stress concentrator, followed by its sealing with an insulating device, i.e. a packer. When a fluid is injected into this slot, the tensile stresses are created in the borehole walls and the fracture is forced to develop in a predetermined direction. The IHF method of the coal seam from the development workings using non-cased degassing holes of large and variable diameter consists in creation of transverse hydraulic fractures in the hole relative to its axis and increasing its gas recovery by an order of magnitude. This is achieved by using a double-sided packer with elastically expanding elements and a valve installed between them. Additional tangential stresses created in the borehole walls ensure the development of inelastic strain zone, leading to the formation of transverse cracks in the borehole. The results of numerical modeling of the stress-and-strain state of the rocks near the borehole where packer seals are installed using the finite element method are presented in the paper. Techniques and means to monitor the processes of hydraulic impact on the coal-rock massif are shown.

Published: December 2022

The topicality of this research is defined by the increasing volume of mining operations near settlements and production infrastructure, as well as by the increasing unit capacity of mining and haulage equipment and, consequently, by the growing volume of rock mass simultaneously blasted and prepared for excavation. Changes in the mining conditions at the operations of UK Kuzbassrazrezugol JSC have been analyzed. A brief analysis of research results on various factors affecting the degree of man-made impact of the blasting operations is presented. One of the ways to safely increase the volume of simultaneously blasted rock mass is the introduction of energy-saving environmentally friendly technologies in production and use of plastic explosives, which would ensure higher completeness of chemical transformations and the efficiency of the blast through the use of special fuel mixtures containing surfactants instead of diesel fuel in the compositions of granular industrial explosives. This will increase the contact surface area of the fuel and the oxidizer by several orders of magnitude as well as the stability and the energy-output ratio of the blasting charges with the zero oxygen-combustible balance. Reducing the consumption of explosives, energy intensity of mining, the man-made impact of blasting operations on the environment, the seismic action of the blast, the radius of the hazardous zone - all of this can be achieved by using charges placed in hoses of variable diameter when blasting wet and dry rock masses. The article shows the dependence of changes in the load on the atmosphere with increasing distance from the blast epicenter and with increasing weight of simultaneously detonated explosives in surface mining operations, as well as the dependence between the yield of fines and the size of the gap between the charge and the charging chamber.

Published: December 2022

Cepten yapılan sağlık harcamaları, bireylerin ve hanehalklarının sağlık hizmetlerinden yararlanmak için doğrudan hizmet sunuculara yaptığı ve kendilerine geri ödemesi yapılmayan harcamalar olarak tanımlanmaktadır. Bireyleri, hanehalklarını ve sağlık sektörü finansmanını etkileyen cepten sağlık harcamalarının belirleyicilerinin tespit edilmesi oldukça önemlidir. Bu çalışmada “Türkiye’de bireylerin ve hanehalklarının cepten sağlık harcaması yapmalarında etkili olan demografik değişkenler nelerdir?” sorusuna cevap aranmaya çalışılmıştır. Bu amaçla Türkiye’de hane halklarının yapmış oldukları cepten sağlık harcamalarını etkileyen faktörlerin karar ağacı algoritmalarından biri olan CHAID algoritması ile belirlenmesi amaçlanmıştır. Bu amaçla, Türkiye İstatistik Kurumu’nun (TÜİK) yayınladığı 2019 yılı Hanehalkı Bütçe Anketi (HBA) verileri elde edilerek CHAID analizi gerçekleştirilmiştir. CHAID analizi bulgularına göre; hanelerin cepten sağlık harcaması yapıp yapmama durumunu etkileyen en önemli değişkenin “reel gelir” değişkeni olduğu belirlenmiştir. Reel gelirin çeşitli düzeylerine göre de “hanede 65 yaş üstü birey olup olmaması”, “hanehalkı reisinin medeni durumu” ve “hanede 5 yaş altı bireyin olup olmaması” değişkenleri cepten sağlık harcaması yapıp yapmama durumunu etkileyen önemli değişkenler olarak belirlenmiştir.

Karşılaştırmalı Edebiyat, hem farklı ulusların hem de toplumların birbirlerini her türlü kültürel unsurlarıyla tanımalarına aracılık etmektedir. Farklı toplumların edebiyat ürünlerinin içeriklerinin ortaya konması ve edebiyat ürünlerinin birbirleriyle karşılaştırılmaları suretiyle yeniden konumlandırılmalarına yardımcı olan edebiyatın bir alt disiplini olarak tanımlanmaktadır. Karşılaştırmalı Edebiyat, edebiyat ürünlerinin, diğer ulus edebiyatlarıyla olan ilişkisi, ilgisi ve konumunun belirlenmesi bakımından önem arz etmektedir. Bu bağlamda Karşılaştırmalı Edebiyat, etkileşimle ortaya çıkmakta ve Karşılaştırmalı Edebiyat Bilimi Yöntemleriyle benzerlik ve farklılıkları ortaya koymak amacıyla yapılan çalışmaları kapsamaktadır. Karşılaştırmalı Edebiyatın, bir ulusa ait edebiyatı, diğer uluslarca da tanınır kılması bakımından önemli bir işlev üstlendiği görülmektedir. Ulusların kendi coğrafyaları içerisinde var olan her türlü kültürel unsuru ortaya çıkarması ve yerel edebiyatın başka ulus ya da milletler tarafından tanınır hale gelmesini sağlama potansiyeline sahip olmasının yanında ulusun kendi edebiyat ürünlerine de ayna tutarak ulus edebiyatına da yön tayin etmektedir. Bu çalışmamızda karşılaştırmalı edebiyatın bağlı olduğu üst disiplin olan Edebiyat ve Edebiyat Bilimleri kavramlarının tanımları yapıldıktan sonra Karşılaştırmalı Edebiyatın, Ulus Edebiyatına işlevselliği bağlamında katkısının ortaya konması amaçlanmıştır. Edinilen bulgularda Karşılaştırmalı Edebiyatın, Ulus Edebiyatını, yerel sınırların ötesine taşımasına aracılık etmesi bakımından önemli bir işlevi olduğu saptanmıştır.

Bu çalışmanın temel amacı sosyal koruma harcamalarının önemli bileşenlerinden biri olan işsizliğe yönelik sosyal koruma harcamaları ve vergi gelirleri arasındaki ilişkiyi nedensellik açısından incelenmesidir. Bu amaç doğrultusunda çalışmada 2000-2019 verileri kullanılarak Türkiye ve PIIGS (Portekiz, İrlanda, İtalya, Yunanistan, İspanya) ülkeleri için bir panel nedensellik testi gerçekleştirilmiştir. Analiz bulgularına göre, Türkiye ve İrlanda’da vergi gelirlerinden işsizliğe yönelik sosyal koruma harcamalarına doğru tek yönlü nedensellik ilişkisi elde edilirken, Yunanistan’da işsizliğe yönelik sosyal koruma harcamaları ve vergi gelirleri arasında çift yönlü nedensellik ilişkisi mevcuttur. Elde edilen bulgular litetatürde yer alan benzer çalışmaların bulguları ile paralellik göstermekle birlikte söz konusu ülkelerde vergi gelirlerinin artırılmasının işsizliğe yönelik sosyal koruma harcamalarına etki edeceğini göstermektedir
