determination-of-heat-demand-and-optimal-production-capacity-for-yeast-production-by-use-of-ms-solver 2020 1 The main cost of production is directly related to the heat demand, the quantity of used raw material and the prices of raw materials and utilities. This value could be optimized. So, the main task of this work would be the minimization of heat energy demand and maximization of production capacity. For these purposes, it was created a simulation model as mathematical function of all inputs and outputs of the analyzed system. That model is based on mass and heat balances for all streams which connect processing units in different modes of work as batch, continuous, semi-continuous and feed-batch. This mathematical model was made in MS Excel. All variables like temperatures and flows are inserted in that worksheet and calculated from set of equations for mass and heat balances. Change of values for input variables (quantity of raw materials), cause changes of all processing parameters and parameters that characterize final products. The optimization is done with MS Solver. That tool use only one parameter as objective for optimization. Because of that, three different objectives were chosen for three different optimization goals for the production processes. Optimization was done as minimization of total heat demand, maximization of final product's capacity and minimization of the common parameter that relate to heating demand and production capacity. The use of the common parameters for heat demand and production capacity gives the best result, because it minimized heat energy and maximizes production capacity. This optimization also created optimal process scheduling as its result.

monitoring-of-the-mosquitoes-in-skopje-2016-and-impact-of-flood-in-municipality-gazi-baba-of-the-mosquitoes-populations 2020 1 In Republic of Macedonia malaria has been eradicated in 1973.Since then control of mosquitoes is a regular measure.In 2010, WHO initiated the re-analysis of the mosquitoes in the territory of the Republic of Macedonia.Today, monitoring of the mosquitoes is providing only in Skopje by team from P.H.O Center for public health – Skopje. Collecting adults of mosquitoes for qualitatively and quantitatively prooving we has been used BG Sentinel traps.There were three traps, one trap in peri-urban area and two traps in urban areas.They were placed for six months and changed the nets every two weeks.Samples were returned in Entomological laboratory in P.H.O.-Skopje. Monitoring has been started in april, when temerature is enlarge and populations of mosquitoes are increases.Traping adults of the mosquitoes in august in peri-urban area Gazi Baba, period of flood, are proof for proportionally increase temerature, humidity and mosquitoes. There were interest results from entomological research on territory of Skopje, our idea is to expand the monitoring all over territory of the Republic of Macedonia.When we have information of species composition of mosquitoes in Macedonia, than we will choose the best way for their control and stop appearance and spreading the patogents.

baker-s-yeast-shelf-life-preservation-in-presence-of-alginates 2020 1 Food products are very sensitive to environmental conditions. That is especially high in a case of Baker`s yeast. Compressed (fresh) Baker`s yeast is actually microorganism`s strain Saccharomyces cerevisiae. It is unstable at temperatures above 4oC. The reason is budding of cells. If that is the case, yeast cells use stored components for feed. After the complete usage of energy components, cells make autolysis. Autolysis is a process at which cell is going to destroy itself. Cytoplasmic juice goes out of the cell membrane and fills intercellular space. The juice is full with water and components useful for other microorganisms. These conditions make ideal environment for growing other microorganisms and decreasing Baker`s yeast shelf life. The change of water content in the product can change its shelf life. There are food additives able to absorb water. They could be used for protecting the product with water absorbing. Two types of additives (alginates) with high water absorption capacity were observed in use added to compressed yeast. Different concentration of Sodium- and potassium alginates were used in preparation samples of yeast. Based on analysis of few product`s parameters, the samples with 0.2% alginate showed the best results in preservation. Increasing of alginate concentration, increase yeast stability, but decrease water solubility. Using of alginates can increase stability of Baker`s yeast quality

remodeling-suburban-settlements-of-skopje 2020 1 In the last decades the citizens of Skopje are witnesses of serious urban degradations in almost any part of the capital. The process of high-speed densification of a built area creates series of side effects like: lack of natural daylight, bigger pollution, absence of proper views, decreasing of green area, diminishing the natural aeration etc. Therefore the unsatisfied citizens are starting to move outside of those extremely dense urban districts looking for cheaper building plots in the existing suburban settlements and looking for better life conditions. The city authorities are not responding to those tendencies in a proper way, because there is no any initiative to create urban plans covering bigger areas than the current DUPs (Detailed Urban Plans) in order to allow a complete and proper development of existing suburban areas. The goal of this paper is to create series and profound analyzes, and to propose new urban project for remodeling suburban settlements in existing location detected as a potential city hot spot. This project will define hospitable dwelling destinations for the possible future users for a long term and it could establish new guidelines for the future urban politics in the Macedonian capital.

assessment-of-teaching-effectiveness-in-engineering-education 2020 1 A framework for evaluation of effectiveness in teaching and learning of core knowledge and professional skills in chemical engineering education has been developed by iTeach EU project (http://www.iteach-chemeng.eu/) consortium, involving six partner institutions from different countries (UK, France, Germany, Portugal, Slovakia and Macedonia). Initial testing of the framework included two teaching units, chemical reactor engineering and design project, as part of the core courses in undergraduate chemical engineering curriculum. Evaluation of six different metrics, such as strategic nature of the course/discipline, relevance of the proposed formation, pedagogical relevance of the teaching approach, perception of relevance of the pedagogical approach, evaluation of acquisitions and evaluation of transfer, being integral parts of the framework, allows easy assessment and comparison of efficiency in teaching among different institutions, as well as easier recognition of the areas of improvement in specific pedagogical methodologies. Moreover, one of the goals of the project has been to establish a tool that could be used in assessment of delivering the core knowledge and employability competences in the education of different scientific disciplines. After some adaptation and improvements, the framework was subjected to a wider testing including stakeholders groups with different educational and professional experiences. The effects of this testing concerning variety of teaching approaches will be elaborated and discussed.

post-covid-19-urbanism-establishing-modular-dimensions-when-designing-new-urban-spaces 2020 1 Because of the global pandemic caused by the COVID-19 virus, many countries around the world are facing the negative consequences of this virus on the health of people. Apart from healthcare, the negative consequences also affect the overall economic and social aspects of the life in the cities. Proposed measures to prevent the spread of the virus include restricting the movement of people in the cities, personal protection and social and physical distancing between people. All this leads to a change in the way cities function as urban centers, the use of buildings and public space. Urbanism and architecture, at the time of the corona virus, have the primary task of organizing the functioning of cities as well as the buildings and spaces in them. This is a challenge for future city planning in order to provide a quality and safe way of life for the residents of the city and the emergence of a new "post COVID-19" urbanism. This paper will present possible solutions for the transformation of urban architectural conditions when designing a given space, specifically through a project for a new modular tourist camp. The solution of the project before the onset of the pandemic will be subject to analysis from the aspect of new dimensioning caused by the recommendations for protection of people. The aim of this paper is to offer modular models in the design of tourist camps by re-dimensioning the micro-urban elements of the camp in the existing dimensioned space. The expected results of this paper will provide an opportunity to apply new modular dimensions of open spaces in order to enable the health safety of citizens and enable the proper functioning of urban spaces
