The first scientific developments in the field of biogas technologies were made in Russia more than 70 years ago. Since the 50th years one of the main directions was the anaerobic processing of activated sludge and sediments of urban wastewater. This method attracted attention in connection with the idea of obtaining biogas mainly from the manure of farm animals. Thanks to this in the middle of 50th years a number of pilot plants for biogas production were built in Zaporozhia, Belorussian, Georgian, Moldavian branches of All-Russian Institute of Agriculture Electrification, and also in Ekaterinburg. However, the operating experience of these installations was insignificant - one - two seasons. The problem of obtaining and using biogas is given great attention abroad. In a short time, in many countries around the world a whole industry for the production of biogas has emerged. The leader in the development of biogas industry is China. Since the middle of 1970, the National Program for the production of biogas from livestock wastes has been operating in this country. Currently, there are 10 million farm bioreactors. In addition, 40 000 biogas stations, 24 000 biogas treatment plants operate in China, which provides operation of 190 power plants.

Abstract. We report on total gaseous mercury (TGM) measurements made in Pudong, Shanghai in August/September 2009. The average TGM was 2.7 ± 1.7 ng m−3. This represents about 90% of the total atmospheric mercury. This is an underestimate for an annual-mean concentration because the meteorology in September favored predominantly easterly oceanic air, replaced in other seasons by airflow from industrial areas. The observed TGM follows a pattern seen in other cities around the world: a background elevated over mean hemispheric background (1.5 ng m−3), and pollution plumes of different magnitude and duration, interspersed with very sharp spikes of high concentration (60 ng m−3). The September 2009 Shanghai measurements are lower than those reported for most other Chinese cities and Mexico City, and similar to concentrations found in some Asian and in North American cities. Such comparisons are tenuous because of differences in season and year of the respective measurements. We find that the observed TGM are most likely coming from coal fired power plants, smelters and industrial sources, based on its high correlation with NOx, SO2, CO and wind directions.

Electrical power is a resource humans heavily rely on, and it has become a basic human need. Today, the major sources of electricity generation are fossil fuels, renewable energy, and nuclear power. This paper concentrates on electricity generated through nuclear power and compares it to the other electricity generation technologies. The objective behind this paper is to discover the impact that nuclear power has on the total electricity generated in Canada, and in addition on a global scale. The paper presents the current role that nuclear power plays in the global electricity generation, and also the expansions that need to be made in the nuclear power industry to fulfill the future electrical power demands. A number of projections have been made based on the current rate of nuclear reactors being put into operation, which is approximately 4 reactors per year, and current term of reactor operation, which is 45 years. These projections were made for the nuclear power in the world. A major outcome of this analysis projects that between 2030 and 2035, the number of operating nuclear reactors in the world can drop by 50%. If this dangerous trend is not addressed, we can lose a viable, and reliable source of energy. The datasets that were analyzed during the process were taken from multiple open literature sources such as journals, reports, and online databases. The paper presents a comparison between nuclear power and other energy sources, and the positive impact nuclear power can have on the world if needed advancements were made in building new nuclear power plants.

Within the last years the idea of running a conventional power plant has changed. Fluctuating power generation by solar power and wind parks creates a need for highly flexible backup power plants. This need quickly arose within the last 5 years and the market is still searching for a solution. Single steam turbine manufacturers can provide features to react more flexibly, quickly and to prolong component life time. Thus, considerable operating experience has already been in existence for many years. New highly efficient steam turbines are already equipped with solutions to serve an ambitious market. But also, for existing units, different modernization packages can be provided along with hardware and software modifications which allow power plants to supply power at a moment’s notice. This paper presents the overall approach and the possible field of application for the well-established features of Siemens steam turbines. Starting a power plant within a short time to fill the gap of fluctuating power generation is an important capability in order to participate in today’s and tomorrow’s energy market. A fully automated start-up procedure to avoid any delays contributes in fulfilling this requirement. Optimized component geometries guarantee the shortest start-up times. Furthermore, a parallel start-up of gas and steam turbines (Hot Start on the Fly) has already been proven for many years. Regarding flexibility, the improvement of start-up time is only one major aspect. Another important task is to provide the opportunity to influence scheduled maintenance outages. Therefore, steam turbines can be equipped with software which allows the customer to plan the power plant’s outages in accordance with single components requirements, e.g. GT outages. The lifecycle counter enables customers to evaluate the optimum between start-up time and life time consumption based on dynamic equivalent operating hours. In addition, fast cooling procedures help to keep outage times to a minimum.

1989 göçü öncesi, dünyada eşzamanlı olarak gittikçe gelişen ve zenginleşen mutfak kültürü, Bulgaristan Türklerini de etkilemiştir. Pazardaki çeşitlilik arttıkça, yemek alışkanlıkları da değişime uğramıştır. Büyük göçten sadece 30-40 sene evvel kısıtlı imkânlar ile sınırlı sayıda yemek çeşidi üretilirken, alım gücünün artmasıyla yemek kültüründe de hızlı gelişmeler olmuştur. Artan ürün çeşitliliği yemeklere de yansımış, farklı lezzetler mutfaklara girmiştir. Göçmen yemekleri denilince hamur işleri, börek ve pideler akla gelir. Ayrıca, göçmenlerin çok zengin turşu, komposto ve konserve kültürüne sahip oldukları da bilinir. Bu çalışma, 1989 öncesi Bulgaristan’ın farklı bölgelerinde yaşayan Türklerin yemek alışkanlıklarına ışık tutmakla birlikte, göç sonrasında göçmen mutfak kültüründe bir değişiklik oluşup oluşmadığını konu almaktadır. Bu amaçla, 1989 yılında Türkiye’ye göç etmiş 50 kişiye 8 sorudan oluşan anket düzenlenmiştir. Bu verilerden yola çıkarak oluşan bulgular derlenmiş ve yeni tespitler yapılmıştır. Ayrıca, Türkiye’nin farklı bölgelerine yerleşen göçmenler, kendi göçmen pazarlarını kurmuşlardır. Bulgaristan’dan getirilen ürünlerin bu pazarlarda satılması böyle bir arz talebin hala devam ettiğine işaret etmektedir.ABSTRACT IN ENGLISHThe Diversity in Cuisine Culture of the Immigrants from Bulgaria After 1989 MigrationThe Cuisine culture that has been developing and getting rich day by day contemporaneously in the world before 1989 migration has also had an impact on Bulgarian Turks. By the increase in diversity in the market, eating habits have changed. While producing a limited number of food types with limited opportunities just some 30 or 40 years before the ‘Big Migration’, there has been a rapid progress in food culture by the help of the increase in purchase power. Enhancing product range has been reflected in food, and different tastes have entered the cuisines. When we say immigrant, the first things that come to our mind are pastry, flan and pitta bread. Moreover, it is also known that immigrants have a very rich cuisine culture of pickle, stewed fruit, and canned food. This study aims both to disclose the eating habits of Turks living in different regions of Bulgaria before 1989 and to determine whether there has been a difference in immigrant cuisine culture before and after the migration. For this purpose, a questionnaire consisting of 8 questions has been administered to 50 people who migrated to Turkey in 1989. The results gathered from these data have been compiled and new determinations have been made. In addition, immigrants that settled in different regions of Turkey have set their own immigrant markets. The fact that the products brought from Bulgaria are being sold in these markets shows that this kind of supply and demand still continues.

The great Uzbek poet Alisher Navoi(1441-1501), during his lifetime, was widely known not only in his homeland, but also far beyond its borders. A contemporary and biographer of Navoi, the famous historian Hondemir, of course, not without some hyperbole, wrote: "He (Navoi -M.Kh.) in a short time took the cane of primacy from his peers; the fame of his talents spread to all ends of the world, and the stories of the firmness of his noble mind from mouth to mouth were innumerable.The pearls of his poetry adorned the leaves of the Book of Fates, the precious stones of his poetry filled the shells of the universe with pearls of beauty

Jamaica, known in the world for her rich deposits of bauxite ore, is a small Caribbean country with an area of 10991 square kilometers and a population of just over two million individuals. This beautifu11and, which was described by Columbus as "The fairest isle that eyes have beheld" has developed a remarkably diversified manufacturing sector starting from a modest industrial base. Jamaica's manufacturing industry enjoyed a respectable growth rate of about 6 percent per annum during the good old days of the euphoric '50s and '60s. However, those bright sunny days ''when to live was bliss" were followed by the chilling winter of much subdued progress. The rise and fall of growth have aroused considerable interest among economists and policy• makers. The book under review probes the causes of this behaviour by analysing key characteristics of Jamaican manufacturing sector and tracing its path of evolution.

The SARS-CoV-2 pandemic is spreading fast throughout the world, and often the new cases are reported as community spread, which means that it is not possible to identify a specific cause for contagion. Household pets and farm animals live closely to humans and even if currently there is no empirical evidence of animal to human transmission, it has not been reported yet if transmission is in principle possible. This work addresses such hypothesis, confirming that transmission is theoretically possible, and highly likely to occur between humans and mammals. Less likely or not likely at all between humans and birds. Further research is needed to validate the birds to humans transmission. -- THIS ARTICLE IS CURRENTLY BEING EXPANDED AND REVISED --
