Saf bir sermaye şirketi olan anonim şirkette çoğunluk ve oransallık ilkeleri geçerlidir. Doktrinde “ne kadar sermaye, o kadar hak (soviel Kapital, soviel Rechte)” şeklinde özetlenen bu ilkeler dolayısıyla, sermayenin çoğunluğuna sahip olan pay sahipleri anonim şirket genel kurullarında diledikleri kararları çıkarmaya gücü yeter konumdadır. Özellikle, şirketi yönetmeye ve temsil etmeye tam yetkili olan yönetim kurulunun seçiminde nitelikli bir çoğunluğun aranmaması, çoğunluk pay sahiplerinin istediği kişiyi yönetim kurulu üyesi olarak atamasını daha da kolaylaştırmaktadır. Bu nedenle azınlıkta kalan pay sahiplerinin şirketin işleyişine olan ilgisi azalmakta, anılan pay sahipleri giderek şirketten uzaklaşmaktadır.
6102 sayılı Türk Ticaret Kanunu (TTK) ile getirilen önemli yeniliklerde birisi belirli grupların yönetim kurulunda temsil edilmesine olanak sağlayan TTK m. 360 hükmüdür. Mezkur hükme göre belirli pay gruplarına, özellik ve nitelikleriyle belirli grup oluşturan pay sahiplerine ve azlığa yönetim kurulu üyeliği için aday önerme veya yönetim kurulu üyesinin bunlar arasından seçilmesi hakkı tanınabilir. Hangi yöntemin tanınmış olmasına bakılmaksızın, belirli gruplara yönetim kurulunda temsil edilme hakkı tanınmışsa, genel kurul bu hakka riayet etmek zorundadır. Bu zorunluluğun sınırı ise haklı sebeplerin varlığıdır. Haklı sebep olmadığı halde, genel kurul bu hakka riayet etmezse genel kurul kararının iptali mahkemeden talep edilebilecektir.

Lately, the expansion of constant checking frameworks and the rise of the Modern Web of Things (IIoT) have uncovered the need of creating calculations that are both adaptable and lined up to gauge mechanical disappointments and decide the excess helpful existence of assembling frameworks and the parts that make up those frameworks. Information driven approaches, for example, AI have acquired importance in the field of prognostics and wellbeing the executives (PHM), as opposed to customary model-based prognostic strategies, which need a significant perception of the actual elements of the framework and frequently rely upon specific stochastic cycles. The critical measure of preparing information that is required, then again, is a hindrance to the computational productivity of AI calculations for information driven PHM. To tackle this trouble, the reason for this study is to give a remarkable strategy to hardware prognostics that utilizes a cloud-based equal AI calculation. In particular, the expectation of hardware wear in dry processing processes is achieved by the utilization of the irregular backwoods strategy, which is a method that is generally used in the field of AI. What's more, an equal irregular woods method is built by utilizing the MapReduce structure, and it is then conveyed on the Amazon Flexible Register Cloud. It has been shown by means of the consequences of the trials that the arbitrary woodland calculation is compelling in delivering expectations that are extremely exact. Likewise, the execution of the equal irregular woods strategy brings about impressive execution gains, which gives additional proof of the calculation's true capacity for functional use in modern settings.

The State of Bahia, Brazil, stands as the predominant global producer of guarana, which is recognized for its seeds’ caffeine-rich composition. This study aimed to determine the concentrations of methylxanthines (theobromine, caffeine, and theophylline) and phenolic compounds (catechin and epicatechin) in guarana leaves, seeds, and pericarps collected from various producing cities in Bahia. High-performance liquid chromatography analysis was conducted, and the data set was subjected to principal component analysis (PCA) for evaluation. Theobromine and caffeine were found in all leaves and pericarps samples, where higher contents were quantified for theobromine. Caffeine was the major compound in seeds, followed by epicatechin and catechin. No statistical difference was observed for the average contents of caffeine in samples from different producing cities. PCA showed no clear guarana sample discrimination based on bioactive compound contents. This study holds substantial relevance for the valorization of guarana cultivation in Bahia, enabling the identification of cultivars harboring elevated levels of bioactive compounds, which can be selectively cloned to meet the demands of the consumer market. Furthermore, the investigation unveils the potential utilization of leaves and pericarps as sources for the extraction of theobromine and caffeine, exhibiting promising applications in the pharmaceutical industry.

Commercial protein bars such as whey protein bars (New Millen® protein complex premium) are consumed worldwide and are usually made with whey as a protein source. Fish protein concentrate (FPC) is an alternative protein of animal origin with a different amino acid profile and fatty acid composition and can be produced from mechanically separated meat (MSM) of Nile tilapia (Oreochromis niloticus). This study investigated FPC for its nutritional characteristics and microbiological quality for the manufacture of protein bars. The FPC-enriched bars presented a potential profile of essential fatty acids for human consumption. The sensory evaluation showed good acceptance scores, with no differences from the control (commercial product) and high purchase intention. The inclusion of 5.3% of FPC in the protein bars with different flavors may be a promising alternative to produce a high nutritional value product for human consumption, besides favoring the sustainability of the fish supply chain.

Past to five decades earlier, the very perception of a women entrepreneur managing her own business firm could have appeared ambitious at the highest points. Women entrepreneurship evolved in spite of problems surrounding it such as discrimination, gender inequalities and many more regressive social norms [2]. A lot of women’s have started their own businesses in order to break free from social constraints. Women proved themselves to be strong innovators. Expressly in some of the economically developing nations, the opportunities offered by women entrepreneurs help grow markets and also increase the employment prospects. But despite progress, the topic is of vital significance because of the challenges which stand still and should be treated as global phenomenon. “There are merely about 10 countries across the globe where entrepreneurship is equal in terms of gender equality [2].” The current global trend founds women owned businesses to be more concentrated in small and medium enterprises with a ratio of overall low-profitability or low-growth sectors. Women’s are found to stick or limit themselves to a range of business choices such as fashion retail, beauty cosmetics and food services [1] & [2]. “In continents of Africa and Asia, approximately 75 percent of women are in these consumer-oriented sectors. They are seldom into mining, construction, electronics and big data technologies” Caren Grown, senior director for gender at the World Bank, advocated [1]. The study highlights current participation of women entrepreneurs in the markets of G20 countries.
The Red Queen Effect and How to Evade the Red Queen Effect by using Generative AI: Preparing Companies for Industry 5.0

The red queen effect is a metaphor used in the business world to describe the unsuccessful efforts of a company to get ahead of its competition. The red queen effect is the need to continually adapt and evolve to maintain relevance in an ever-changing environment. Companies must constantly innovate and find new ways to stay ahead of the competition to ensure their survival and success. Companies typically research or study the competition and then implement strategies to help boost their company sales and profits. This is an effective and practical method of outmaneuvering the competition. While this technique works in theory, companies might not achieve their goals because the competition engages in the same business practice. Despite a company’s efforts to surpass the competition, the company does not move forward or grow. The aims of a research paper are bifold firstly, it attempts to identify the contributions of the RQE theory and secondly, to enable corporates to evade the Red Queen Effect by using generative artificial intelligence to be prepared for Industry 5.0.

"Rapid changes in the world climate are drawing particular attention to the polar regions, where microplastic pollution is recognized as an increasing problem as well as other environmental problems. Various studies have shown that the seemingly pristine polar regions are under threat from microplastics and micropollutant pollution. As a result of research activities in recent years, knowledge on these polar issues is increasing. However, it is understood that the transport pathways of microplastics into the Arctic and Antarctic Oceans have not been sufficiently investigated. Although concentrations reported in a limited number of studies indicate that microplastics are ubiquitous globally, there are large variations in measured quantities. This is thought to be a consequence of the complex mechanisms governing the transport of microplastics despite the risk of cross-contamination, ranging from synthetic clothing used in the study areas, to limited laboratory facilities and even ship conditions. In this paper, we discuss whether microplastics originate from local sources at the poles or are transported by wider circular ocean currents surrounding the continent. To date, the absence of robust quantitative evidence has left this critical question unanswered, complicating efforts to understand the origin of microplastics in this ecologically sensitive environment."

"In this study, microplastics, 16 PAHs sorbed on microplastics and the risk caused by microplastics were detected in surface water samples in Konya Closed Basin. The total of microplastics was determined as 1138 and 23444 MP/m3. Fragment (51%) microplastics were detected dominantly in the surface waters of the basin, followed by fiber (34%), film (10%), pellets (3%) and foam (2%). In terms of color distribution, approximately 70%of the microplastics detected are transparent and white, followed by blue, black, green, brown, yellow, pink, purple, orange and red were detected. 34% of microplastics are polyethylene (PE), 25% polypropylene (PP), 24% cellophane (CP), 12% polydiene (PD) and 5% polycarbonate (PC) type polymers. According to the contamination factor evaluation, 38% of surface waters were determined to be very highly polluted (CF>6). According to polymeric risk assessment, medium risk (10<H<100) was determined. According to the pollution load index values, it was determined that the PLI value of the regions in the basin and the entire basin was greater than 1 and was classified as a polluted region. It has been determined that the surface waters in the basin are close to residential areas and are exposed to pollution from traffic and agriculture. PAH concentration due to microplastics in surface waters was detected between 393-24755 ng/g. Sources of PAHs have been identified as domestic fuel use, traffic-related diesel engines, oil pollution, and factory emissions. It is necessary to take precautions in terms of microplastic and PAH pollution in the surface waters in the basin."

"In this study, the current situation of macropollutants in Northern Cyprus is summarized, as well as the scientific results obtained from a small number of local studies on micropollutants and endocrine disruptors are discussed. Although Cyprus, the third largest island in the Mediterranean, has limited industrial pollution; due to its tourismbased economy, it is exposed to an increasing pollution burden due to the increasing population and inadequate environmental protection activities. This pollution load, especially from domestic and agricultural sources, shows its negative effects, and in addition to visible events such as solid waste landfill fires and uncontrolled wastewater discharges, there is also an increase in micropollutants that are invisible but have significant effects. According to the results of some research carried out within the Cyprus International University, endocrine disruptors such as pesticides and phthalates have been investigated in the TRNC and promising results have been obtained from advanced treatment studies."
NANOPLASTİKLERİN SUCUL EKOSİSTEM ÜZERİNDEKİ ETKİSİ: ZEBRA BALIĞI MODELLEMESİ

"As of the mid-twentieth century, objects made of plastic materials began to become a part of humankind’s daily life. It is estimated that there are around nine billion tons of plastic products on Earth. Unfortunately, today we have to face plastic pollution that is difficult to deal with because we cannot properly manage the waste management of this mass production. In this article, attention is drawn to the potential risk of nano-sized plastic fragments constantly released from both in-use and waste plastics. Plastics consist of polymer chains connected to each other by the weak Van der Waals interaction. This structure of plastics allows environmental stresses to break off continuous particles, including nano sizes, from the main material. Studies have proven that these nano-sized plastic particles, which are even included in the hydrological cycle, have a greater risk potential on living things than their larger counterparts. These studies have shown that nano-sized particles can enter the organism’s systems, spread and accumulate in their bodies, cause damage at the cellular level, negatively affect the organism’s behavior, and even cause cancer-related damage in the next generation. At this point, it is important to include nanoplastics within the scope of global plastic pollution. Although it seems very difficult to completely eliminate plastic pollution, we can minimize this exposure by taking simple precautions in our daily lives."

Изучение роли Катара в ближневосточной политике США в 1970-1990-е годы дает возможность выявить влияние США в становлении Катара как государства. Динамика развития американо-катарских отношений, особенности этих отношений позволяют проанализировать развитие сотрудничества в указанный период в сфере обороны. Проведенные исследования позволяют заключить, что США сыграли решающую роль в процессе становления Государства Катар, став гарантом стабильности и безопасности Катара, что и определило будущее место и роль Катара в регионе и на международной арене. Катар, в свою очередь, стал политической и стратегической движущей силой США в ближневосточном регионе благодаря своей гибкой и осмотрительной внешней политике.
Studying the role of Qatar in the US Middle East policy during the period of 1970s- 1990s provides an opportunity to observe the influence of the US in the establishment of Qatar as a state. By analyzing the development dynamics of US-Qatar relations and hig- hlighting the features of those relations, it is possible to analyze the US-Qatar defense cooperation during the said period. The analysis shows that the US played a crucial role in establishing the State of Qa- tar and became the guarantor of Qatar's stability and security. This determined Qatar's future place and role in the region and on the international platforms. Thanks to its flex- ible and prudent foreign policy, Qatar became a political and strategic driving force for the United States in the Middle East region.
