Abstract:

Hyaluronan is a polysaccharide with multiple functions in the human body being involved in creating flexible and protective layers in tissues and in many signalling pathways during embryonic development, wound healing, inflammation, and cancer. Hyaluronan is an important component of active pharmaceutical ingredients for treatment of, for example, arthritis and osteoarthritis, and its commercial value far exceeds that of other microbial extracellular polysaccharides. Traditionally hyaluronan is extracted from animal waste which is a well-established process now. However, biotechnological synthesis of biopolymers provides a wealth of new possibilities. Therefore, genetic/metabolic engineering has been applied in the area of tailor-made hyaluronan synthesis. Another approach is the controlled artificial (in vitro) synthesis of hyaluronan by enzymes. Advantage of using microbial and enzymatic synthesis for hyaluronan production is the simpler downstream processing and a reduced risk of viral contamination. In this paper an overview of the different methods used to produce hyaluronan is presented. Emphasis is on the advancements made in the field of the synthesis of bioengineered hyaluronan.

Abstract:

Today, one of the most widespread processes in modern oil refining is the production and purification of hydrogen, which is used in the production of ammonia, methanol, and plastics. Without it, the production of high-quality motor fuels is impossible, since this gas is involved in the hydrogenation process (hydrotreating) [1]. Currently, at oil refineries and petrochemical plants, hydrogen is obtained in two ways: from natural gas by steam reforming into a mixture of hydrogen and carbon monoxide (synthesis gas), in a catalytic reforming unit, where a mixture of hydrogen and light hydrocarbon gases (hydrogen-containing gas) is released. Most modern oil refineries have a hydrogen production unit, its widespread use in industry is explained by its chemical activity, ease of production and high exothermicity of the process [2].

Abstract:

Vegetable grafting is most common in European and Asian countries where crop rotation is no longer an option and available land is under intense use. Grafting is an alternative approach to reduce crop damage resulting from soilborne pathogens and increase plant abiotic stress tolerance, which increases crop production. We discuss and outline four grafting methods that are available for vegetable production in cucurbits: tongue approach grafting, hole insertion grafting, one cotyledon grafting, and side grafting.

Abstract:

The article deals with creating a methodology for assessing cartographic production; the study showed that political, economic, scientific and technical factors make the main influence over its development. The relevance of the research is due to modern requirements for an objective display of production development, the progress and regression of which is evidenced by the change in quantitative indicators over time. The methodology is based on the analysis of the identified quantitative indicators, such as releasing cartographic products (for the entire history of development) and their abrupt changes, defined by the author as its indicators, which enable determining the degree of the factors influence. A weighted point assessment of the impact of the political, economic, scientific and technical determinant on cartographic production in the period under review was obtained; that made it possible to construct and visualize an integrated graphic model in the period from 1705 to the present. To compare the results, an expert approach to evaluation of production is proposed; it is expressed by experts in the rational arrangement of the problem analysis with the quantitative assessment of judgments and processing of their results. An assessment of cartographic production in Russia is carried out based on the developed methodology at all stages of historical development

Abstract:

Conventional fuels are not renewable resources and are getting depleted day by day. In addition, the by-products of the combustion of these fuels cause environmental problems. This situation, which threatens the world, has led to the search for new energy sources. Hydrogen, as an energy carrier, creates a potential for solving these problems. Hydrogen is the most abundant element in the universe, with the highest energy content per weight of all conventional fuels. But unlike conventional fuels, hydrogen is not easily found in nature and is produced from primary energy sources. Therefore, it is a renewable fuel. When used in a fuel cell, only water is produced as a by-product. From this point of view, when compared to any fuel, it stands out as a fuel with the highest energy content and does not contain carbon. The biggest problem in using hydrogen gas as a fuel is that it is not found in nature and economically cheap production methods are needed. Hydrogen can be produced in two different ways, biological and chemical. Chemical methods are not preferred because they are costly. Biological methods, on the other hand, are low-cost, sustainable, environmentally friendly methods. In this study, information of hydrogen energy and its historical development is given. Thus, a projection is made for the importance and future of hydrogen energy. Then, hydrogen production methods are explained and compared. In addition, information about hydrogen storage types is given.

Abstract:

Aboveground container production revolutionized woody plant production. In-ground pot-in-pot container production combines the benefits of container production with traditional field production. Our objective was to determine the specific costs of production for field-grown, aboveground container, and pot-in-pot production methods for Lagerstroemia indica. We found differences in production cost with varying levels of input required by each production method. Pot-in-pot production systems had higher fixed and variable costs and a higher initial capital investment compared to the other two production methods. However, per unit production costs were similar to aboveground container production due to lower labor and equipment requirements.

Abstract:

Due the implementation of nanotechnologies in the pharmaceutical industry over the last few decades, new type of cutting-edge formulations—nanopharmaceutics—have been proposed. These comprise pharmaceutical products at the nanoscale, developed from different types of materials with the purpose to, e.g., overcome solubility problems of poorly water-soluble drugs, the pharmacokinetic and pharmacodynamic profiles of known drugs but also of new biomolecules, to modify the release profile of loaded compounds, or to decrease the risk of toxicity by providing site-specific delivery reducing the systemic distribution and thus adverse side effects. To succeed with the development of a nanopharmaceutical formulation, it is first necessary to analyze the type of drug which is to be encapsulated, select the type matrix to load it (e.g., polymers, lipids, polysaccharides, proteins, metals), followed by the production procedure. Together these elements have to be compatible with the administration route. To be launched onto the market, the selected production method has to be scaled-up, and quality assurance implemented for the product to reach clinical trials, during which in vivo performance is evaluated. Regulatory issues concerning nanopharmaceutics still require expertise for harmonizing legislation and a clear understanding of clinically compliant production methods. The first part of this study addressing “Nanopharmaceutics: Part I—Clinical trials legislation and Good Manufacturing Practices (GMP) of nanotherapeutics in the EU” has been published in Pharmaceutics. This second part complements the study with the discussion about the production scales and clinically compliant production methods of nanopharmaceutics.

MF is a manufacturing company oriented in the manufacture of water transportation products. The product raised in this study is a mass-produced product by PT. MF. The problem experienced by this company is that the process system in production has not been formed so that it affects the performance of production to produce output in the process. The purpose of this research is to create and find the best production process system so that productivity or production performance can be increased. The average weekly product demand that can be produced by the production department is 10 units, while the average product currently produced is only around 4 units per week. The method used in this research is simulation with the help of promodel software. As for the data used, it was obtained from the results of observations, tests, and measurements of working time and interviews that have been conducted with the team in the field. In the initial steps of the research, observations and analysis are carried out to find the core problems that occur. After the problem is found, then an analysis is carried out to solve the problem so that finally it is continued to make a process model by means of simulation. From the results of the simulation analysis, there are 4 proposed process system models that can be used to achieve increased production performance. Of the 4 proposals, there is 1 proposal that can increase production output results to 300 percent from the previous results and from the other 3 proposals, it can increase output results by more than 300 percent, namely as many as 15 units per week. This increase can be achieved by adding several work stations and the number of working hours each day.

Abstract:

Two methods developed by Prof. Dohányos and Doc. Zábranská from ICT in Prague (A) and Oxi Top Control AN 12 measuring system manufactured by MERCK Company (B), were used to determine the maximum yield of biogas and methane and the maximum rate of biogas and methane production per unit weight of biomass using buffered and macro- and micro-nutrient enriched grass biomass as a substrate. Statistical evaluation proved that the Oxi Top Control method did not provide significantly lower or higher results than the other method that is considered standard. Although the Oxi Top Control AN 12 method has a higher variance of measured values than the standard method, it can be recommended as a project and operation method for its work comfort and expeditiousness.

Abstract:

Most commercial sweetpotato acreage in the United States is grown from plants that have been produced from bedded roots. Development of new methods or new combinations of known methods to increase plant production helps to maximize the number of usable plants produced in a minimum amount of time and also reduces propagation costs while aiding early transplanting. Plant production is influenced greatly by genotype, and many efforts have been directed at improving plant production from sparse plant producing cultivars. Modifications of wounding or cutting treatments, exposure to chemical sprout inducers, presprouting by heat treatments and combinations of these treatments have enhanced plant production from large and small roots of sparse and profuse plant producing cultivars.

Abstract:

[For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version)].ABSTRACT The essence of roundabout methods of production, according to the author, is that the ultimate goal of the process, which is to provide consumer goods, is achieved through creation and sales of intermediate products, which are capital. The use of such techniques improves efficiency of production, so the growth of «roundaboutness» is a dominant trend of economic development. The specifics of transport aspect in this case is the fact that transport connects various stages of production chain, located at different points in space, and thus has spatial roundaboutness effect, which is the most pronounced in today’s global economy. The effectiveness of development of global economic production chains increases with the absence of barriers to movement of goods, capital and labor and with availability of market pricing, not distorted by regulatory action. Keywords: transport, roundabout production, spatial roundabout effect, capital, global economy.

Abstract:

Современная ситуация, связанная с производством серы из природного газа и накоплением большого количества попутной элементарной серы, приводит к усложнению экологической обстановки. Эта проблема требует немедленного решения, необходим поиск новых путей производства из элементарной серы ценных материалов. Сера – крупнотоннажный вид химического сырья, имеющая множество аллотропных модификаций и кристаллических форм, свойства которых зависят от способа получения, наличия примесей и условий хранения. Полимерная сера представляет собой нерастворимую модификацию серы. Полимерная сера применяется в производстве высококачественных шин, резины, серобетона и в других областях промышленности. Целью данной статьи является научно-аналитический обзор текущих технических достижений в области производства полимерной серы из природного и попутного сырья. Использованы материалы мировой периодической научной, научно-технической и патентной литературы. Статья раскрывает особенности промышленных методов производства полимерной серы, применяемых в настоящее время в мировой практике. В объем обзора входит обсуждение путей получения нерастворимых форм серы и направление их применения. Описаны способы производства полимерной серы, технологические, эксплуатационные трудности при применении конкретного метода. Рассмотрены ключевые этапы методов производства и получения полимерной серы, отражены их преимущества и недостатки, а так же проведен анализ основных проблем производства серы. Наибольшее внимание уделено термическим методам получения нерастворимой серы, таким как газификация и метод охлаждения расплава, в виду их наибольшей распространенности и более глубокой технической проработки. Показано, что в настоящее время нет серьезных изменений в конструкциях производственного оборудования, технологических линий и параметров процессов. Существуют общие проблемы, такие как низкое содержание продукта, низкая термическая стабильность, плохая диспергирумость, накопление статического электричества во время производственного процесса, небезопасное производство и высокий расход CS2. The production of sulfur from gas the accumulation of a large amount of elemental sulfur. This complicates the environmental situation. The problem requires immediate resolution. It is necessary to find new ways to produce valuable materials from elemental sulfur. Sulfur is a large-tonnage type of chemical raw material that has many allotropic modifications and crystalline forms. The properties of allotropes depend on the production method, the presence of impurities and storage conditions. Polymeric sulfur is an insoluble modification of sulfur. Polymeric sulfur is used in the production of high-quality tires, rubber, sulfur concrete and in other areas of industry. The purpose of this article is a scientific and analytical review of the current technical achievements in the field of polymer sulfur production from natural and associated raw materials. The review is made on the basis of materials of world periodic scientific, scientific and technical and patent literature. The article reveals the peculiarities of industrial methods of polymer sulfur production currently used in world practice. The scope of the review includes discussion of ways to produce insoluble forms of sulphur and the direction of their application. Described are methods of producing polymer sulfur, technological and operational difficulties when using a specific method. Key stages of methods of production and production of polymer sulfur are considered, their advantages and disadvantages are reflected, as well as analysis of main problems of sulfur production is carried out. The greatest attention is paid to thermal methods for the production of insoluble sulfur, such as gasification and melt cooling method, in view of their greatest prevalence and deeper technical development. It is shown that at present there are no major changes in the structures of production equipment, process lines and process parameters. There are common problems such as low product content, low thermal stability, poor dispersibility, accumulation of static electricity during the production process, unsafe production and high CS2consumption.
