Value-at-Risk Estimation with Normal Distribution Approach on Stock Return of BBNI and BBRI
Authors: Susanti Dwi
Published: February 2023

This paper discusses risk analysis on a single stock return. Stock data analyzed are shares of BBNI and BBRI. The method used is Value-at-Risk with a normal distribution approach. The steps are, after obtaining stock returns, then the value-at-risk (VaR) is estimated using a normal distribution approach. Then a back-test is carried out to measure the performance of risk measures. The results of the analysis show that VaR for BBNI and BBRI produces a small QPS close to zero. This shows that VaR with the normal distribution approach is more consistent and can be used to measure risk for BBNI and BBRI.Â

Published: February 2023

Yoga and meditation address mind and body, affecting many molecular processes like metabolism, epigenetic, oxidative processes, and subjective well-being. In this review, we have compiled the results of various clinical trials that have looked into the effect of yoga-based intervention programs on gene expression changes in peripheral blood mononuclear cells (PBMCs). Most yoga-based interventions aided in the maintenance of genomic stability through maintenance of telomere length and showed improvement in innate immunity. However, there is a lack of randomization and variability in the duration of intervention programs across studies. So, future trials should focus more on rigorous methods and reporting adequate sample size and randomization.Aim:To explores the effect of yoga on physical health through observable molecularchanges in the form of differential gene expression and the molecular changes underpinning psycho physiological benefits.Materials and Methods:we reviewed different types of Mind body interventions (MBIs) of various observable molecular changes in the form of differential gene expression.Result and discussion:This review adds to the ever-growing literature on the effects of Yoga/MBIs on health and disease, specifically the changes in the regulation of gene expression levels.Conclusion:our reviewarticle suggests that a comprehensive yoga program induces significant gene expression changes. By adopting a yoga and meditation-based lifestyle, we surely can slow down the pace of our biology or chronological age
USAR decision-making: the role of hazard-specific expertise and risk assessment
Authors: Brooks Benjamin , Curnin Steven , Brooks Oliver
Published: February 2023

The accepted detrimental effects of climate change and the anticipated increased frequency of cascading disasters means there is a pressing requirement to equip search and rescue teams with the capability to perform effective and complex risk assessments. This paper investigates risk-based decision-making expertise in the aftermath of the 2011 earthquake and tsunami in Japan. It compares the actual decisions made by an Urban Search and Rescue (USAR) commander, with the decisions that a cohort of people working within search and rescue made, when provided with the same decision context using 3 vignettes. Variations in the results are explored in terms of the complexity of the risk decision and the type of expertise required. The findings indicate that as the risk becomes more complex, the percentage of answers that were the same as the USAR commander (that we deem as ‘correct’ as they did not result in any adverse outcomes for the USAR team) decreased. Training entities need to provide decision-makers with the necessary human capabilities so they can perform the complex risk assessments required to make decisions in low-probability yet high-consequence disasters.

The epigenetic of the panic disorder
Authors: Smail Harem Othman
Published: February 2023

From this review, I discussed the epigenetics of panic disorder .epigenetic is the changes in the heritable phenotype without any change from the DNA sequence. The roles of different types of epigenetics (DNA methylation and chromatin remodeling) have been controversial from one study to another. The researcher focused on the roles of the candidate genes in the development and progress of panic disorder .there different candidate genes located the different chromosomes such as 1q, 2p, 2q, 3, 7, 9, 11, 12q13, 12q23, and 15 that may be used as markers give for the future promise to diagnosis panic disorder in early life span. Recently, no studies have demonstrated gene therapy's roles in treating panic disorder, and the basic contribution of interventions such as exposure, cognitive therapy, relaxation training, and breathing retraining has not yet been identified. Differences between these patients that assess the efficacy of exposure-based cognitive-behavioral therapy and related neuroplastic changes can be demonstrated by altered protection signal processing and anterior cingulate cortex-amygdala coupling
A DEEP LEARNING NETWORK FOR MODELLING THE RELATIONSHIP OF THE REAL GDP, CO2 EMISSION AND RENEWABLE ENERGY CONSUMPTION FOR TURKIYE
Authors:   Centrade Fulfillment Services co-founder, Izmir, Türkiye, Tuncsiper Cagatay
Published: February 2023

In this study, the relationship between Türkiye’s real gross domestic product, CO2 emission and renewable energy consumption is modelled using machine learning techniques. The data between 2003-2020, the period when renewable energy production and consumption have accelerated, are included in the modelling. First of all, it was tested whether there is a causal relationship between the real gross domestic product, CO2 emission and renewable energy consumption data. Afterwards, a deep learning model was developed in Python programming language by considering the real gross domestic product as the dependent variable while CO2 emission and renewable energy consumption are considered as independent variables. The developed deep learning model has two input nodes, three hidden layers consisting of 100 neurons each, and an output node. In addition, the rectified unit functions are used as nonlinear activation functions in the deep learning network. Based on the standard usage, seventy percent of the data was used as the training data and the remaining thirty percent were employed as the test data. The results of the developed deep learning network and actual gross domestic product data were compared, and it is shown that the developed deep learning network successfully models the relationship between the real gross domestic product, CO2 emission and the renewable energy consumption. The coefficient of determination of the developed model was calculated in Python environment as R2=0.986. This parameter value also indicates that the developed deep learning network model has a good performance for the modelling of the real gross domestic product dependent on the CO2 emission and renewable energy consumption.
EVALUATION OF CALCIUM OXIDE NANOPARTICLES TO ENHANCE HEAVY METAL STRESS TOLERANCE IN PLANTS
Authors: Modi Gajanand , Babita Babita , Arora Bhumika , Shivani Shivani , Bhardwaj Nivedan
Published: February 2023

Heavy metal contamination is a severe environmental problem affecting global food production and safety. Heavy metal stress due to its toxicity, bioaccumulation, and non-biodegradability, it become quite serious in nature. The available strategies for preventing heavy metal contamination are not frequently used because of their inefficient and time- or money-consuming properties. Recent developments in nanotechnology have been made based on ameliorative strategies which have a potential alternative to physic-chemical methods. Under heavy metal stress, the application of calcium oxide nanoparticles (CaO-NPs) significantly boosts plant biomass, anti-oxidative enzyme activities (such as catalase (CAT), ascorbate peroxidase (APX), superoxide dismutase (SOD), and glutathione reductase (GR)), and the level of non-enzymatic antioxidants (ascorbate and glutathione). Additionally, CaO-NPs enhance the gene expression linked to anti-oxidative enzymes. It can be suggested that CaO-NPs could be used as a potential chemical to reduce heavy metal uptake and toxicity in the plants grown under heavy metal contaminated soil. This review provides an overview of plant-CaO-NPs research in increasing heavy metal stress tolerance in plants.

Authors: Heqi Zhao , Halabi Khairun Nisa Mustaffa
Published: February 2023

Expansion of businesses and industrialization has led to depletion of natural resources and has turned the  concerns of the global communities, especially countries like China and America, on. The excess population  of China has led to creating huge depletions of natural resources and carbon emissions. This is why China is  now considering green initiatives as compulsory and important for mitigation of negative environmental  impacts, negative impacts on the growth of economy, and on the health and literacy of the common man.  Therefore, the aim of the current study was to analyze the various factors that lead to increased opportunity of  buying from online domains. The framework presented within this study entails that social and environmental  sustainability awareness and health literacy can lead to enhancing the purchase decisions of smart and green  products such as smart light. Altruism has been used as a connection variable between these factors as  altruistic nature of consumer has shown toenhance the buying behavior. The conceptual framework presented  din this study needs to be validated through empirical research in the future.

Film Societies in Germany and Austria 1910-1933
Authors: Cowan Michael
Published: February 2023

This study traces the evolution of early film societies in Germany and Austria, from the emergence of mass movie theaters in the 1910s to the turbulent years of the late Weimar Republic. Examining a diverse array of groups, it approaches film societies as formations designed to assimilate and influence a new medium: a project emerging from the world of amateur science before taking new directions into industry, art and politics. Through an interdisciplinary approach—in dialogue with social history, print history and media archaeology—it also transforms our theoretical understanding of what a film society was and how it operated. Far from representing a mere collection of pre-formed cinephiles, film societies were, according to the book’s central argument, productive social formations, which taught people how to nurture their passion for the movies, how to engage with cinema, and how to interact with each other. Ultimately, the study argues that examining film societies can help to reveal the diffuse agency by which generative ideas of cinema take shape.

question for the research. It insists above all on the role played by furniture
within the exhibiting logic put on stage in these spaces. It thus reinterprets
the ancient saying Ubi Papa, Ibi Roma (Rome is where the Pope is) and
comes to highlight the relationship between “container and content”. It

sideboards and other architectural structures.
Tracking the Genealogical Reasoning Reconstruction of Nahdlatul Ulama (NU) Fiqh: From ‘Social Fiqh’ to ‘Civilization Fiqh’
Authors: Fauzi Nazar Reza , Fahmi Abdul Hamid Mohammad
Published: February 2023

Fiqh, or in another term were called as Islamic jurisprudence, are the conceptions which are required by the Muslims to organize their interests in all aspects of life, provide the basics of the system of worship, administration, commerce, politics, social, and civilization. This article aims to trace and elaborate on the term "Civilization Fiqh.," or known as “Fiqh Peradaban”. It was initiated by Nahdlatul Ulama (NU) towards its one-century birth. By exploring and unraveling the genealogy of substantive thinking on the countenance of NU Fiqh as the epistemological basis for the ideas of “Civilization Fiqh”. The library method is used in writing this article. This article uses a descriptive-analytic approach; it tries to explain in an analytical-consistent manner through rigorous reading to unravel the transmission of the NU Fiqh reasoning constructions to obtain a fresh and modern formulation of "Civilization Fiqh.” The results of the discussion of this article include 1) It needs reading and interpretation of the reasoning of the Pesantren tradition to redefine the Islamic scientific tradition, which is seen as less adaptive to the changing realities of the new world order but has not lost its identity by the currents of modernity; 2) NU needs to expand the discussion of “Civilization Fiqh” not only on political issues and the nation-state. This genealogically was carried about simultaneously by NU activists, academics, ulama, even PBNU itself (2000-2019). Issues related to human rights (labor fiqh), injustice, gender (women fiqh), extraordinary crime (anti-corruption fiqh), and environmental destruction (energy fiqh, waste management fiqh). So it is no exaggeration if “Civilization Fiqh" in the future can discuss the reality of 21st-century society: free economy, internet technology society of think, building the smallest nation element: family with counter-discourse which capture the trending issue of childfree, demography fiqh, etc.
High-spatial-resolution retrieval of cloud droplet size distribution from polarized observations of the cloudbow
Authors: Pörtge Veronika , Kölling Tobias , Weber Anna , Volkmer Lea , Emde Claudia , Zinner Tobias , Forster Linda , Mayer Bernhard
Published: February 2023

Abstract. The cloud droplet size distribution is often described by a gamma distribution defined by the effective radius and the effective variance. The effective radius is directly related to the cloud's optical thickness, which influences the radiative properties of a cloud. The effective variance affects, among other things, the evolution of precipitation. Both parameters can be retrieved from measurements of the cloudbow. The cloudbow (or rainbow) is an optical phenomenon that forms due to the single scattering of radiation by liquid cloud droplets at the cloud edge. The polarized radiance of the cloudbow crucially depends on the cloud droplet size distribution. The effective radius and the effective variance can be retrieved by fitting model simulations (stored in a lookup table) to polarized cloudbow observations. This study uses measurements from the wide-field polarization-sensitive camera of the spectrometer of the Munich Aerosol Cloud Scanner (specMACS) aboard the German “High Altitude and LOng range research aircraft” (HALO). Along with precise cloud geometry data derived by a stereographic method, a geolocalization of the observed clouds is possible. Observations of the same cloud from consecutive images are combined into one radiance measurement from multiple angles.
Two case studies of trade-wind cumulus clouds measured during the EUREC4A (ElUcidating the RolE of Cloud-Circulation Coupling in ClimAte) field campaign are presented, and the cloudbow technique is demonstrated. The results are combined into maps of the effective radius and the effective variance with a 100 m × 100 m spatial resolution and large coverage (across-track swath width of 8 km). The first case study shows a stratiform cloud deck with distinct patches of large effective radii up to 40 µm and a median effective variance of 0.11. specMACS measures at a very high angular resolution (binned to 0.3∘) which is necessary when large droplets are present. The second case study consists of small cumulus clouds (diameters of approximately 2 km). The retrieved effective radius is 7.0 µm, and the effective variance is 0.08 (both median values). This study demonstrates that specMACS is able to determine the droplet size distribution of liquid water clouds even for small cumulus clouds, which are a problem for traditional droplet size retrievals based on total reflectances.
Radiative effect by cirrus cloud and contrails – A comprehensive sensitivity study
Authors: Wolf Kevin , Bellouin Nicolas , Boucher Olivier
Published: February 2023

Abstract. Natural cirrus clouds and contrails cover about 30 % of the Earth's mid-latitudes and up to 70 % of its Tropics. Due to their widespread occurrence, cirrus have a considerable impact on the Earth energy budget, which, on average, leads to a warming net radiative effect (solar + thermal-infrared). However, whether the instantaneous radiative effect (RE) of natural cirrus or contrails is positive or negative depends on their microphysical, macrophysical, and optical, as well as radiative properties of the environment. This is further complicated by the fact that the actual ice crystal shape is often unknown and thus ice clouds remain one of the components that are least understood in the Earth's radiative budget. The present study aims to separate the effect on cirrus RE of eight parameters: solar zenith angle, ice water content, ice crystal effective radius, cirrus temperature, surface albedo, surface temperature, liquid water cloud optical thickness of an underlying cloud, and three ice crystal shapes. In total, 94,500 radiative transfer simulations have been performed, spanning the parameter ranges that are typically associated with natural cirrus and contrails. The multi-dimensionality and complexity of the 8-dimension parameter space makes it impractical to discuss all potential configurations in detail. Therefore, specific cases are selected and discussed. The ice crystal effective radius has the largest impact on solar, thermal-infrared (TIR), and net RE. The second most important parameter is the ice water content, which impacts the solar and terrestrial RE equally. Solar and TIR RE have opposite signs, meaning that the ice water content has a relatively small impact on net RE. Beyond the ice crystal effective radius and the ice water content, the solar RE of cirrus is determined by solar zenith angle, surface albedo, liquid cloud optical thickness, and the ice crystal shape in descending priority. RE in the TIR spectrum is dominated by the surface temperature, the ice cloud temperature, the liquid water cloud optical thickness, and the ice crystal shape. Net RE is controlled by the surface albedo, the solar zenith angle, and the surface albedo in decreasing importance. The relative importance of the studied parameters differs depending on the ambient conditions and during nighttime the net RE is equal to the TIR RE. The data set generated in this work is publicly available. It can be used to compute the radiative effect of cirrus clouds, contrails, and contrail cirrus instead of full radiative transfer calculations.
UGS-1m: fine-grained urban green space mapping of 31 major cities in China based on the deep learning framework
Authors: Shi Qian , Liu Mengxi , Marinoni Andrea , Liu Xiaoping
Published: February 2023

Abstract. Urban green space (UGS) is an important component in the urban ecosystem and has great significance to the urban ecological environment. Although the development of remote sensing platforms and deep learning technologies have provided opportunities for UGS mapping from high-resolution images (HRIs), challenges still exist in its large-scale and fine-grained application due to insufficient annotated datasets and specially designed methods for UGS. Moreover, the domain shift between images from different regions is also a problem that must be solved. To address these issues, a general deep learning (DL) framework is proposed for UGS mapping in the large scale, and fine-grained UGS maps of 31 major cities in mainland China are generated (UGS-1m). The DL framework consists of a generator and a discriminator. The generator is a fully convolutional network designed for UGS extraction (UGSNet), which integrates attention mechanisms to improve the discrimination to UGS, and employs a point-rending strategy for edge recovery. The discriminator is a fully connected network aiming to deal with the domain shift between images. To support the model training, an urban green space dataset (UGSet) with a total number of 4544 samples of 512×512 in size is provided. The main steps to obtain UGS-1m can be summarized as follows: (a) first, the UGSNet will be pre-trained on the UGSet in order to obtain a good starting training point for the generator. (b) After pre-training on the UGSet, the discriminator is responsible for adapting the pre-trained UGSNet to different cities through adversarial training. (c) Finally, the UGS results of 31 major cities in China (UGS-1m) are obtained using 2179 Google Earth images with a data frame of 7′30′′ in longitude and 5′00′′ in latitude and a spatial resolution of nearly 1.1 m. An evaluation of the performance of the proposed framework by samples from five different cities shows the validity of the UGS-1m products, with an average overall accuracy (OA) of 87.56 % and an F1 score of 74.86 %. Comparative experiments on UGSet with the existing state-of-the-art (SOTA) DL models proves the effectiveness of UGSNet as the generator, with the highest F1 score of 77.30 %. Furthermore, an ablation study on the discriminator fully reveals the necessity and effectiveness of introducing the discriminator into adversarial learning for domain adaptation. Finally, a comparison with existing products further shows the feasibility of the UGS-1m and the great potential of the proposed DL framework. The UGS-1m can be downloaded from https://doi.org/10.57760/sciencedb.07049 (Shi et al., 2023).
Bayesian age–depth modelling applied to varve and radiometric dating to optimize the transfer of an existing high-resolution chronology to a new composite sediment profile from Holzmaar (West Eifel Volcanic Field, Germany)
Authors: Birlo Stella , Tylmann Wojciech , Zolitschka Bernd
Published: February 2023

Abstract. This study gives an overview of different methods to integrate information
from a varve chronology and radiometric measurements in the Bayesian tool
Bacon. These techniques will become important for the future as technologies
evolve with more sites being revisited for the application of new and
high-resolution scanning methods. Thus, the transfer of existing
chronologies will become necessary because the recounting of varves will be
too time consuming and expensive to be funded. We introduce new sediment cores from Holzmaar (West Eifel Volcanic Field,
Germany), a volcanic maar lake with a well-studied varve record. Four
different age–depth models have been calculated for the new composite
sediment profile (HZM19) using Bayesian modelling with Bacon. All models
incorporate new Pb-210 and Cs-137 dates for the top of the record, the
latest calibration curve (IntCal20) for radiocarbon ages as well as the new
age estimation for the Laacher See Tephra. Model A is based on previously
published radiocarbon measurements only, while Models B–D integrate the
previously published varve chronology (VT-99) with different approaches.
Model B rests upon radiocarbon data, while parameter settings are obtained
from sedimentation rates derived from VT-99. Model C is based on radiocarbon
dates and on VT-99 as several normal distributed tie points, while Model D
is segmented into four sections: sections 1 and 3 are based on VT-99 only,
whereas sections 2 and 4 rely on Bacon age–depth models including additional
information from VT-99. In terms of accuracy, the parameter-based
integration Model B shows little improvement over the non-integrated
approach, whereas the tie-point-based integration Model C reflects the
complex accumulation history of Holzmaar much better. Only the segmented and
parameter-based age integration approach of Model D adapts and improves
VT-99 by replacing sections of higher counting errors with Bayesian
modelling of radiocarbon ages and thus efficiently makes available the best
possible and most precise age–depth model for HZM19. This approach will
value all ongoing high-resolution investigations for a better understanding
of decadal-scale Holocene environmental and climatic variations.

Amaç: Bu araştırmanın amacı genç yetişkinlerde algılanan sosyal destek ve kendini açmanın dijital oyun bağımlılığı üzerindeki yordayıcı rollerini incelemektir.
Yöntem: İlişkisel tarama modeline göre yapılandırılan bu araştırmanın katılımcılarını 382 genç yetişkin birey oluşturmaktadır. Katılımcılar uygun örnekleme yöntemiyle seçilmiştir. Araştırmada veri toplama aracı olarak Kişisel Bilgi Formu, Dijital Oyun Bağımlılığı Ölçeği, Kendini Açma Ölçeği ve Çok Boyutlu Algılanan Sosyal Destek Ölçeği kullanılmıştır.
Bulgular: Yordayıcı modelin dijital oyun bağımlılığındaki varyansın %58’ini açıkladığı görülmüştür. Ayrıca analiz sonucunda kendini açmanın miktarının (β = -,08, p,05), özel insandan algılanan destek (β = ,04, p>,05), niyet (β = ,04, p>,05), olumluluk (β = ,05, p>,05) ve dürüstlük (β = ,02, p>,05) alt boyutlarının ise dijital oyun bağımlılığının anlamlı bir yordayıcısı olmadığı bulunmuştur.
Sonuç: Araştırmada algılanan sosyal desteğin artmasının dijital oyun bağımlılığı üzerinde etkisi olmadığına ulaşılmıştır. Bir diğer sonuç olarak, kendini açma davranışının artmasının dijital oyun bağımlılığını azaltıcı bir etkisi olduğu dikkate alındığında kendini açma davranışı dijital oyun bağımlılığında koruyucu faktörlerden biri olarak ele alınabilir.

Lithostratigraphic features and structure of the Precambrian of the Rhodopian Supergroup in the Ivaylovgrad and Krumovgrad areas, East Rhodope Mountains
Authors: Kozhoukharov Dimitar
Published: February 2023

The Rhodopian Supergroup is represented in the lvaylovgrad and Krumovgrad areas by the rocks of the Rupčos Group: the Čepelare Varied Formation, Bogutevo Plagiogneiss formation, and Vâča Varied Formation. The three formations are distinguished for the first time in this part of the East Rhodope Mountains. The Čepelare Formation occurs here in a more specific manner. Three members are gradually outlined from the west to the east between the villages Padalo and Kamilski Dol. They have also a varied composition, but each of them is dominated by a particular rock variety: Yailadžik Member (mainly gneissose), Tumbata Mcmber (schists to gneiss-schists) and Kamilskidol Member (predominantly am phibolitic). The members are introduced here for the first time. The rocks of the three members interfinger to the west and so uthwest of the village Popsko with the undivisible Čepelare Formation from the Avren syncline. The Bogutevo and Vâča Formations (in incomplete sections) have a composition and characteristic features similar to that in the type area, and differ from the typical development by the increased amount and dimensions of the ultrabasic bodies. The rocks of the Rhodopian Supergroup are polymetamorphic products which in their present shape are a result of multiphase superposition of metamorphic alterations (different in type and intensity) during the Precambrian and the Phanerozoic stages of their development. With the except ion of the low-temperature hydrothermal metamorphism (serpentinization) and the early high-baric metamorphism proven for the metaultrabasics and eclogites, the metamorphic processes in all other rock varieties had the following sequence: Precambrian regional amphibolite facies metamorphism; Precambrian (Riphean) regional migma tization; regional greenschist facies diaphthoresis (at the Precambrian – Phanerozoic bound ary); Early Alpine metamorphism (pregranitic, pre-Upper Cretaceous); contact metamorphism related to the Upper Cretaceous granitic intrusions; Late Alpine (Paleocene – Quaternary) dynamomctamorphism.
Conditions for accumulation of coal-bearing formations in South-Eastern Europe during the Carboniferous
Authors: Popova Katya , Rusanov Ivan , Mogilev Aleksandr
Published: February 2023

Some general regularities of the evolution of sedimentation in the regional structures of South Eastern Europe during the Carboniferous have been derived by an analysis of the location of four large coal basins as the Dobrudzha and Svoge basins in Bulgaria and the Donetsk and Lvov-Volinsk ones in South-West USSR. Direct relationship between the general regressive direction of tectonic movements and the orogenic stage of development of Variscan folded zones were established. This relationship is best defined in the western parts of the studied region where the coal-bea ring formations are characterized by more polymictic terrigenous rocks, better defined rock sequences and increased amounts of pyroclastics in the sediments. The location of the main supp ly areas of deposited material was marked. Thus the Ukranian shield represents the main source of deposition during the accumulation of coal-bearing of the Donbass and Lvov-Volinsk basin. The sources of deposition during the formati on of the Svoge basin were the Sudet mountaneous series of the intermountanous valley. The general suppl y of terrigenous material for the Dobrudzha basin was secured by the North-Bulgarian uplift of the Caledonian mountain located to the south. The sedimentation character of the region studied is coastal (Donbass and Lvov-Volinsk basins) and alluvial-deltaic with all intermediate patterns (Svoge and Dobrudzha basins).
Basic morphostructural features of Pre-Paleogene basement of the Upper Thracian Depression and its cover.

Published: February 2023

The results of the detailed geologo-geophysical research in the Upper Thracian Depression are presented. Original geologo-structural map is drawn up in scale- 1:100 000, revealing Pre-Paleogene basement relief. The existing of the generalized longitudinal blocky structures - Stryama-Harmanli horst and Momino-Marbas-Sokolitza trough, is proved. The Maritza trough is extended south-eastwards and it is suggested, that during the Paleogene wider negative depression region, including in the area of Upper Thracia the north-western parts of the contemporary Borovishka volcano structure of the East Rhodopes depression , has existed. The concept for the existing of the so-called "Chirpan step" as elevated cross blocky structure in the Pre-Paleogene basementis is not confirmed. The relative tectonic independence of the Plovdiv and Zagora depressions and their entity in the structure of the Upper Thracian Depression is reflected as a result of the development and the interaction of the regional deep fault as early as the Upper Cretaceous time. The regularities in the disposition of terraced and mosaic small block structures from higher rank are determined. Maps of the isothickness of the Paleogene and Neogene and maps of the upper boundary relief of the Paleogene are drawn up. They give a complete idea for the inner structure of the Upper Thracian Depression. For the predominant part of the studied area the Neogene inherits the direction of the tectonic movements of the Paleogene . Separate sections with diverse direction of the vertical movements, as well as with horizontal slip fault and left rotation shifting are delineated. It is suggested, that the Late Alpine tectonic of the region is controlled by the basic longitudinal structural elements of the PrePaleogene basement. The received largescale pattern about the geological and lithostratigraphic evolution of the separate fault-blocky structures enables to assert that the block-stratified structure is typical for the upper part from the section of the earth crust in the Upper Thracian Depression.

The rising concern that the effect of climate change on population health risk is gradually generating significant attention. This no doubt influenced the exploration of climate change (co2) emission on population health risk in the case of relating African to different income regions. This study made use of fixed panel cross-sectional analysis, descriptive analysis and correlation coefficient index to estimate the study objective which was to investigate the effects of climate change (co2) emission on population health risk among different country income regions from 2000 to 2021 from the World Bank Indicators (WBI) across the selected income countries and region. Findings showed that climate change (Co2) emission per capita, gross domestic product per capita, and food production index, have negative and significant effects on population health risk, whereas, urban population defecation has a positive and significant effect on the population health risk among different country regions. Specifically, carbon dioxide emissions (C02) (c02empc) are highly associated with High-Income countries (HIC) when compared to other income regions. Hence, argued that attention should be to infrastructural sustainability and provision to maintain a clean environment. In addition, more energy should be channelled into food production and livestock production, especially for low-income regions to mitigate the overall effects of carbon dioxide emissions (C02) (c02empc) to tackle food security. Urgent policy actions and responses to air and water quality as useful adaptation strategies in the wider context of climate affect resilience for low-income regions like SSA countries.
