Published: November 2023

Clan culture is an organizational culture that emphasizes collaboration, teamwork, and employee well-being. The study examined the relationship between clan culture and business performance in Nigeria. Clan culture is seen to be intertwined with ethnic groups and cultural heritage in Nigeria, and it is characterized by loyalty, trust, and solidarity. This culture fosters a shared sense of responsibility and collaboration, increasing employee satisfaction, engagement, productivity, and overall performance. However, clan culture can also present challenges, such as nepotism and favoritism within clans, which can hinder merit-based decisionmaking processes.. However, it can also lead to resistance against change and a reluctance to challenge prevailing norms. Organizations with a strong clan culture, such as Google, Zappos, and Pixar, consistently observe superior employee retention rates. However, the emphasis on maintaining harmony can hinder creative thinking and adaptability, especially in fast-paced, competitive markets. To capitalize on the benefits of clan culture while overcoming challenges, organizations should promote transparency, fairness, and meritocracy, fostering an inclusive environment that embraces diverse perspectives and fosters innovation. By adopting strategies that balance strong relationships with an open, adaptable, and diverse work environment, Nigerian businesses can capitalize on the benefits of clan culture while overcoming challenges Keywords: Hierarchy Clan Culture; Business Performance; Opportunities; Collaboration

Analysis of the State of Degradation of the Endemic Argan Tree (Argania spinosa (L.) Skeels) in Morocco
Authors: Laaribya Said
Published: November 2023

The argan grove is one of Morocco's most emblematic and endemic forest ecosystems, covering an estimated 871,210 hectares. Despite the low average density of its stands, the exceptional qualities of the argan tree (Argania spinosa (L.) Skeels) have made it a focus of attention for scientists, local communities, foresters, tourists and others. The aim of the study is to present a spatial remote sensing diagnosis of the forestry situation. The methodology adopted focused on the use of spatial remote sensing using high-resolution satellite images and field checks, which is proving to be a highly valuable tool, providing a synthetic overview and highly accurate spatial measurements. An analysis of the dynamics of argan areas reveals several indicators of degradation. Indeed, in addition to human activities, the de-densification of stands and the reduction in cover, the argan forest provides only a limited quantity of ecosystem services and retains only limited biological diversity. The urgent need to conserve the argan tree plantation urges the public authorities to take the necessary steps to reverse the degradation of this endemic specie in Morocco.

Authors: Nur Ahmet , Nur Nur Sabah
Published: November 2023

While human beings carry out many activities to continue their lives, they also pollute the nature in which they live. The negative effects of the result of this natural pollution are also first experienced by human beings. One of the negative effects that has become increasingly important in recent years is global warming. With the industrial revolution, carbon dioxide (CO2) gas, the amount of which has increased exponentially every year, is the biggest component of the greenhouse gas that causes global warming. Combustion is the most important factor in air pollution. Combustion events can be of natural origin such as forest fires, vegetation fires, volcanoes. Combustion events can also be caused by domestic heating, industrial activities, and motor vehicle use. The carbon footprint is used to indicate the amount of greenhouse gases released into the atmosphere in terms of carbon dioxide equivalent. As a result of the activities of individuals and organizations, such as energy consumption and transportation, direct or indirect carbon emissions occur. In many countries of the world and in Türkiye, the most increasing footprint is caused by carbon. Countries sign agreements with organizations such as the Kyoto Protocol to reduce the impact of greenhouse gases. To reduce fuel consumption and reduce the gases released by fossil fuel vehicles to the environment, vehicles with electric vehicle technology have started to take their place on the roads today. In this study, information about internal combustion engine vehicles and electric vehicles is given. Then, the effects of electric vehicles on the carbon footprint in Türkiye are examined and suggestions are made.

Authors: Çalış İlayda , Güzel Kaya Gülcihan
Published: November 2023

Carbon dioxide (CO2) is one of the main greenhouse gases which contribute to global warming. CO2 concentration is increasing around the world day by day. It is estimated that CO2 concentration will be approximately 570 ppm in 2100. Many carbon capture and storage techniques have been developed to reduce CO2 emission. Adsorption with using low-cost solid adsorbents is a promising CO2 capture technique. In this study, low-cost biochar/slag composites were evaluated as a CO2 adsorbent. Firstly, neat slag was modified with different concentrations of HCl solution (0.25, 0.50, 1.00, 3.00 and 5.00 M). Maximum surface area and pore volume were achieved through the 1.00 M HCl modification. So, biochar/slag composites were prepared using 1 M HCl modified slag and various amount of biochar (1, 3 and 5 wt%). Structural and morphological properties of the biochar/slag composites were investigated by Fourier transform infrared spectroscopy (FTIR) and field emission scanning electron microscopy (FESEM) analyses, respectively. To examine surface charge of the biochar/slag composites, point of zero charge (pHpzc) measurements were conducted. CO2 adsorption studies were carried out with volumetric sorption analyzer at ambient conditions. The biochar/slag composite including 3 wt% biochar showed maximum CO2 adsorption capacity. With the addition of 3 wt% biochar, CO2 adsorption capacity of the 1 M HCl modified slag increased from 0.10 mmol g-1 to 0.18 mmol g-1. The possible CO2 adsorption mechanisms of the biochar/slag composites are thought to be electrostatic attractions and hydrogen bonds as well as pore filling. The results revealed that the biochar/slag composites can be used as novel and low-cost CO2 adsorbents.

Published: November 2023

Global warming and climate changes have caused an increase in the frequency and intensity of forest fires in recent years, which in turn exacerbates the climate change speed with the emissions of carbon from burned plant biomass. This paper deals with the comparative study of forest fire in the forest laws of Iran, France, Türkiye and South Africa countries to identify the national solutions in dealing with wildfires and to suggest the best solutions. Comparative law is among the best ways to study the legal solutions of specific countries to learning from each other’s and improve the laws. Comparative law has five steps: the first step is the determination of the scope and delimitations of the study, which in this research includes the selection of the mentioned four countries and the topic of forest fires; The second step is the description and analysis of legal materials; The third step is the Comparison of laws and show the similarities and differences; The fourth step is the explanation of the reasons for similarities and differences and the fifth step is the evaluation of laws and provide best solutions of the studied countries in the field of wildfire control. The categories extracted from the content of legal articles and the classification of categories with a common meaning together showed that the legal measures of combat wildfire can be classified into four main pillars as well as the following sub pillars: 1- Measures before fire include a) limitations, regulations and preventive measures, b) cleansing, c) screening, firebreak and prescribed fire, d) fire protection associations, e) determination of high-risk areas and fire risk rating. 2- Measures during fire outbreaks include a) Custodian of fighting fire and providing equipment, b) right of way, servitude, possession, intervention, c) firefighting tactics and use of controlled fire. 3- Measures after the fire include a) Improvement and sanitation measures, b) Prohibitions, regulations, evaluation and review, c) Revival and restoration, d) Incentives, compensation, and 4- Crimes and punishments. Evaluation of the legal solutions of the studied countries showed that some countries have performed well in some pillars and sub-pillars and poorly in some others. South Africa provides considerable provisions by establishing a law specific to fire. However, French legislators have done well in this field by setting up appropriate legal requirements and prohibitions during fire season. While the forest firefighting laws of Türkiye and Iran are scattered throughout the text of the forest law and are not sufficient. Finally, by using the strengths of the laws of the studied countries, the weak points of the national forest laws are identified and recommendations suggest to modify. Also, this research introduces a legal framework to classify national forest laws in the field of forest fire management.

Published: November 2023

The rapid increase in urban population density has put tremendous pressure on urban ecosystems and infrastructure, resulting in an array of environmental issues. Blue/green infrastructure has emerged as a viable solution for addressing these issues by creating resilient urban settings. This abstract revisit the concept of blue/green infrastructure and emphasizes the importance of nature-based, smart solutions and methods. The blue/green structure refers to a network of designed and natural landscapes such as green spaces, parks, wetlands, sustainable drainage systems, and rivers that all work together to improve air quality, manage stormwater, offer recreational places, and increase biodiversity in metropolitan settings. Smart solutions like advanced sensor technologies, data analytics, and Internet of Things (IoT) integration can improve the efficiency and efficacy of blue and green infrastructures. They provide real-time monitoring, informed decision-making, and adaptive management for long-term urban development. Nature-based strategies that include the restoration and maintenance of natural bionetworks in urban environments. These measures not only provide numerous conservation advantages, but they also help in the adaptation and mitigation of climate change. Our cities can lower flood risk, lessen urban heat island effect, sequester carbon, and increase overall urban resilience by utilizing natural power. The global data show the importance of improving the blue/green structure. According to a United Nations estimate, around 55% of the world's population lives in cities, with that proportion expected to rise to 68% by 2050. Furthermore, metropolitan areas account for more than 70% of global greenhouse gas emissions, emphasizing the importance of sustainable urban growth. The World Health Organization estimates that urban air pollution causes 4.2 million premature deaths per year. This research emphasizes the significance of incorporating smart solutions and nature-based techniques into urban planning and design in order to improve blue and green infrastructure. Cities may establish resilient and sustainable environments that will increase citizens' well-being, encourage natural biodiversity, and reduce the impacts of the changing climate.

Published: November 2023

The degradation of glaciers is one of the most obvious signals of climate change in the current period of Earth's history. Modern glaciation is unevenly distributed between different regions of the Earth and some river basins. Glaciers in Georgia are spread over the Great Caucasus Range, concentrated in the basins of the Enguri, Rion, Kodori, Tergi and other rivers, where there are mountain peaks of 3500 m and higher. The study of the melting of glaciers due to the ongoing climate change is extremely important to clarify natural events of a glacial nature, to ensure the rise of the sea level and the safety of the population living in the coastal zone, to determine the change in glacial water runoff and to assess the risks related to the melting of glaciers in general, to develop adaptation strategies and mitigation measures to the melting of glaciers. In the article, the glaciers of the Autonomous Republic of Abkhazia (hereafter “Abkhazia”) and their characteristics are studied. High-resolution satellite remote sensing (SRS) is the only way to study the current state of glaciers in the Autonomous Republic of Abkhazia, because on the one hand, there is no local glaciology school, and on the other hand, the current political situation does not allow conducting expeditions and studying glaciers in field conditions. The objective of the article is to study the morphology and exposure of these glaciers and snowfields based on the data from the catalogue of the former USSR (hereafter “catalogue”) which is called initial data and is obtained from more than one century of observations and is issued between 1960 -1975 and satellite data, at several time points, namely 2010 and 2015 that are derived from high-resolution (30 m) LANDSAT satellite data, and the latest 2020 data are processed from satellite MODIS (1.5 m resolution). Complexly using the best international practices, processed SRS data and several SRS databases, historical data and expert knowledge define the reliability of received data. It should be noted that the authors had to overcome several difficulties and ambiguities in the data to discuss the problem relevantly.

Published: November 2023

Nowadays, the rapid development of technology increase fiber laser cutting machine’s cutting dynamics day by day, these dynamics, such as speed, acceleration, and jerk, refer to the quantitative measures used to describe the motion of an object. In order to enhance these dynamics, it is imperative to modify the design of the motion mechanism. We can employ more powerful electrical or magnetic motor for motion system however dimensional constraints limits this implementation. The aim of this study evolves mechanical design and manufacturing material of Y axis. “Y axis” significant part of the machine which assembly “fiber cutting head” resemblance bridge over the machine main body. Steel alloys predominantly recognize as preferred manufacturing alloy material for this part on account of manufacturing in addition processing of steel parts comparatively effortless than aluminum-based alloys additionally welding and assembly process require more knowledge than production of steel alloys-based material. Aluminum is an economically viable and lightweight metal with the ability to undergo heat treatment and withstand relatively high levels of stress. It ranks among the easily produced high-performance materials, thereby contributing to reduced manufacturing and maintenance costs. Aluminum production process known higher level carbon dioxide emission. “Aluminum Institute reported 11.2 t CO₂/t Al through primary aluminum production and 0.2 t CO₂/t Al through secondary aluminum production.” “World Steel Association, in the year 2020 data's when examining the average emissions per unit of steel produced in 2020, it is each metric ton of steel contributed to the release of approximately 1.89 t CO₂/t into the atmosphere." Based on the presented data, it is evident that the carbon dioxide emissions associated with the production of 1 ton of aluminum are approximately six times higher than the carbon dioxide emissions from steel production. The incorporation of an aluminum-based Y-axis in the machinery has led to a notable reduction in weight. Consequently, the two servo motors responsible for actuating this component will consume less electrical current during its operation throughout the machinery's operational lifespan. This decrease in electrical power consumption is expected to translate into a discernible advantage in terms of CO2 emissions over a specific timeframe, thereby will make aluminum bridge a probably more environmentally favorable choice. This article provides of how to enhance of machine dynamics with using aluminum based “Y axis” in addition that such as carbon footprint, manufacturing process. Upon the conclusion of the research, a comprehensive analysis will be provided regarding the advantages and disadvantages of employing an aluminum “Y axis” rather than a steel “Y axis” in terms of design considerations.

Heavy metal pollution is one of the most critical environmental problems threatening the environment and human health. Therefore, studies on monitoring and reducing heavy metal pollution are among the prioritized study topics. Plants are one of the most effective tools to monitor and reduce heavy metal pollution. However, the potential of heavy metal accumulation in various organs of plants is quite different. Therefore, it is necessary to determine the most suitable species and organs for this purpose and to have information on the transfer of heavy metals in the plant and the way of entry into the plant. In this study, the concentrations of Gallium, one of the most critical and dangerous heavy metals for human health, were evaluated at different soil depths in the soils where Pinus nigra Arnold., Pinus sylvestris L., Fagus orientalis Libsky. and Abies nordmanniana subsp. bornmülleriana Mattf. species grow in leaves, bark, wood, cones, and root organs. As a result of the study, there was no statistically significant difference between soil depths in terms of mean values of Gallium concentrations. In contrast, the highest importance on a species basis was obtained in Fagus orientalis Libsky. The lowest values were obtained in Abies nordmanniana subsp. bornmülleriana Mattf. Regarding organs, the lowest values were obtained in wood and the highest in roots.

Ajara stands out among Georgia's other regions due to its unique physical and geographical conditions. The strong humid subtropical climate, beginning with seaside beaches and swampy lowlands and ending with Alpine meadows - a set of diverse landscapes, rich water, and forest resources, almost evenly distributed resorts and other resort-related places throughout the entire territory of the region - the wealth concentrated in a relatively small area resulting in a growing interest in the economy and natural ecosystems of Ajara. It is crucial to investigate the dynamics of climatic parameters in the Adjara region. The dynamics of air temperature and sea level changes from 1956 to 2015 were analyzed at a distance to assess the level of climate change in the Adjara region. The study was based on observation data from the National Environment Agency and weather stations operating on the Black Sea coast in the past and present. Long-term meteorological data processing was analyzed statistically, climatologically, and graphically to determine climatic changes. As a result of the research, it was discovered that the air temperature in the Ajara coastal area fluctuates dramatically against the backdrop of global climate change, with noticeable warming and cooling periods. The average annual temperature in Adjara's coastal zone (Batumi and Kobuleti) is 14.65 °C/30 years (1986-2015). Batumi's 30-year average temperature is 0.5 degrees Celsius higher than Kobuleti's. When temperatures on the Adjara coast were compared over two thirty-year periods (1956-1985 and 1986-2015), it was discovered that they increased by 0.49-0.69 °C/60 years, while sea level increased by 235 mm/60 years.
Silvicultural Practices in the Process of Climate Change in Turkish Forests
Authors: Yavruoğlu Sena , Yücesan Zafer
Published: November 2023

Forests are important ecosystems in mitigating the effects of climate change and combating climate change. Forests, which are the most important renewable energy sources, are the largest carbon pool after the oceans. Türkiye’s forests, which are spread over three different plant geographies, are densely forested areas where arid and semi-arid climatic conditions are observed and which may be sensitive to climate change stress. On the other hand, forest fires in the Mediterranean basin also pose a significant threat to Turkish forests. Within the scope of combating climate change, it is important to prevent deforestation, to preserve the natural stand structures in existing forest areas, to improve the growth and increment characteristics of stands under appropriate stand structures to the extent permitted by the growing environment characteristics of the stands. Guaranteeing natural regeneration conditions through stand tending works and preferring natural regeneration in forest areas where it is possible are important principles of silviculture. On the other hand, there is an important amount of forest area in the Turkish forests where the canopy is none or degraded and which should be subjected to rehabilitation and restoration works in this context. In today's world where habitat and forest area losses are experienced, it is of great importance to carry out pioneering studies to protect forest genetic resources against climate change, to carry out tree breeding studies and to eliminate the problem of seed migration that may occur in the future due to climate projections. Silvicultural techniques, depending on the sustainable management approach in forestry, constitute an important assurance within the scope of combating climate change. Forest tending works are very important for forests to act as an important carbon sink. Mixed stands in which broad-leaved species are also included in the mixture sequestrate more carbon than pure stands. Especially the presence of individuals with thick diameters in the stands increases the carbon sequestration even more. The duration of the rotation period in even-aged stands and the length of the rotation period in uneven-aged stands are determinant in the amount of carbon sequestration of forest ecosystems. The repetition time and intensity of silvicultural treatments are also directly affected carbon sequestration. In this study, general evaluations were made about the silvicultural practices that should be concentrated in order to increase carbon sequestration in forest areas in Türkiye, the issues that should be considered in practice in stands were evaluated and recommendations were made considering future projections.

Published: November 2023

One of the strategies to alleviate forest fire intensity is the reduction of fuel loading through regular pruning and collection of forest litter. The critical question, however, is whether the regular removal of forest litter in a well-managed black pine (Pinus nigra Arnold) plantation significantly affects the soil respiration rates (Rs) as the forest plantation ages. This study aims to determine the Rs rates across a chronosequence of well-managed plantations of black pines, which have been subjected to regular pruning and collection of forest litter resulting in reduced forest litter inputs. A field experiment in a split-plot randomized block design with five replications was established to measure Rs rates using an automated soil respiration machinery (LI-8100 A). Results showed significant differences in soil Rs rates (p <.0001) across the chronosequence of P. nigra forest, with the oldest stand (60-year-old) showing a significantly highest Rs (2.39 µmol m-2 s-1) compared to the 15-year-old (1.87 µmol m-2 s-1), 30-year-old (1.99 µmol m-2 s-1), and control (1.98 µmol m-2 s-1). Significant differences in Rs rates were also detected across time (p <.001), but not with the interaction effects between age and time (p = 0.85). The Rs showed a positive correlation with soil temperature (r = 0.67), suggesting that it tends to increase with soil temperature. In contrast, the Rs negatively correlated with soil moisture (r = -0.45), suggesting an inversely proportional relationship. We concluded that the impacts of regular removal of forest litter to reduce fuel load are unlikely to significantly affect the soil Rs rates at younger to intermediate age classes. But the Rs tends to increase at a mature age (60 and up), suggesting the tendency of higher Rs rates in mature forests regardless of regular pruning and collection of forest litter removal.

Forest tree species are very important in terms of carbon sequestration. Trees store 50% to 75% of the carbon they take up from the atmosphere in their wood, and the rest is released back into the atmosphere during respiration. Douglas fir is forest tree species native to North America, but shown successful growth and high productivity and quality in Europe. Douglas-fir is also considered as a species with high carbon sequestration, with the yearly average carbon storage of 46,46 kg CO2/year and for this reason it is increasingly popular as a tree for planting. This research aims to select the best provenances of Douglas fir for carbon sequestration in the provenance test in Bosnia and Herzegovina. Material for this research were Douglas fir trees in provenance test in Bosnia and Herzegovina, locality Batalovo brdo near Sarajevo. The provenance test was established in 1966. by planting 2+2-year-old seedlings, and included 5 provenances from Washington, Oregon and Canada, and from altitudes of 150-900 m above the sea. Heights and diameter at breast height of 52-year-old trees were measured, and volumes of trees were calculated. The results showed that the lowest average volume had provenance from the altitude of 900 m, 83-3.0 (0.7313 m3), and the highest provenance from 300 m, 65-1,0 (1.3410 m3). If there are 625 trees per ha, provenance 83-3,0 would produce 457 m3/ha, and provenance 65-1,0 838 m3/ha, which indicates differences in carbon sequestration. The obtained results can be used in selection of provenance for using in introduction of Douglas fir in Bosnia and Herzegovina.

Every year in Kazakhstan, the number of industries is growing, respectively, and environmental pollution, and especially air pollution. The government cannot refuse and close the industry, as well as the citizens themselves in economic terms, so let's look at one of the best trees that can help us cope with this difficult task. Paulownia is a genus of trees in the Paulownia family. It grows in Southeast Asia (especially in China), where it has been grown for decorative, cultural and medicinal purposes for more than 2000 years. It is also known as the princess tree, the royal tree, the Kiri tree, the Empress tree and the phoenix tree, and its Chinese name is 泡桐 (pāotóng). It is believed that the genus Paulownia includes from 6 to 17 species, depending on the taxonomic classification. Of these, P.tomentosa, P.elongata, P. Fortune and P. catalpifoliaare considered the most popular.

Published: November 2023

Seagrasses are the only true plants that live completely submerged in the sea and are particularly abundant and diverse in tropical waters. It is necessary for filtering and holding sediments and thus keeping the water over the coral reefs clearer. The aim of this work is to integrate and compare the type of parameters that can influence the characteristics of a certain species by analyzing their morphometric and physicochemical variables. This study uses the unsupervised learning algorithms such as k-Means and Principal Component Analysis in determining the morphological and physicochemical characterization of four seagrass species. Among all the species observed Enhalus acoroides had the most morphological variation regarding of the length of longest leaf which has the highest value. This means that this species of seagrass is the most sensitive to the environmental conditions prevailing in the study site. Hence, seagrass conservation is hereby encouraged to promote more seagrass areas in the country.
RELATING “FINGER MATHEMATICS”TO THE PRODUCT OF BINOMIALS
Authors: Juanita M. Costillas
Published: November 2023

Finger Mathematics is considered a home-owned procedure as claimed by a majority of the freshmen college students of Southern Leyte State University-Main Campus, Sogod, Southern Leyte. This had been taught to them by most of their parents and was strengthened in their elementary mathematics. This procedure is even observed in high school without the effort of memorizing the multiplication table. Respondents do not have the idea on why this procedure works nor do their teachers in their elementary and high school explained the basis for this procedure. In this study, how finger mathematics works is given emphasis with an expose’ on its formula and proof wherein the product of binomials explains very well the role of the raised and down-curled fingers in the procedure. In this case, finger mathematics which has been used in the area for about a century, contributed to the importance of basic mathematics in its development which has direct implications in Algebra.

Repurchase intention is a very important goal for retail businesses in the competition in the 4.0 technology age. This study aims to explore the mechanism of forming repurchase intention in relation to perceived value and consumer satisfaction in e-commerce. Structural equation modeling was used to evaluate the relationship between perceived value, satisfaction, and repurchase intention. The results show that the role of satisfaction and perceived value positively affects repeat purchase intention. Research results support the means end chain theory and imply that retail businesses need to pay attention to policies to increase perceived value and satisfaction, thereby stimulating repeat purchase intentions of customers.

Introduction: Lifestyle medicine is an increasingly valued field in medicine. Based on scientific evidence, it addresses key health-related behaviors, which are the root causes of most premature deaths, chronic diseases, and health care costs. In a university context, the lifestyle of faculty directly and indirectly impacts undergraduate learning. Objective: This study aims to understand the overall scenario of the lifestyle of medical professors at a private university in São Paulo, to enable future assertive strategies to improve the lifestyle of this population. Materials and Methods: A statistical evaluation of 95 anonymous faculty members was conducted using an online questionnaire consisting of 4 questions about the perception of current health, need and motivation for change, along with the Fantastic Lifestyle Questionnaire, answered between November 2021 and May 2022. Results: From the subjective responses, there is a perceived need for change in the pillars of physical activity (64.2%), mental health/stress management (46.3%), weight management (46.3%), and sleep improvement (35.8%). Through the Fantastic Lifestyle Questionnaire, it is noted that 32% of the faculty have a lifestyle classified as "regular" or "needs improvement"; 89.5% of respondents do not meet the World Health Organization's recommendation for physical activity; 31% report being 8kg or more above their ideal weight; 48.4% complain of non-restorative sleep. Conclusion: In this study, we discuss the possible associations between work conditions, the difficulties in maintaining healthy lifestyle pillars, and how an unfavorable aspect of lifestyle can negatively impact one or several lifestyle pillars. A better understanding of these relationships is crucial for outlining more assertive strategies for the health of faculty and, consequently, better training for future doctors.
