In the face of many global challenges, including ongoing climate change, policymakers are seeking viable solutions. The bioeconomy and its development are one of them. Partnerships, such as BIOEAST, are established to support the development of the bioeconomy in CEE countries. The conversion of biological biomass into new bio-products with high added value can contribute to a reduced environmental impact. One of the three economic sectors producing biomass for manufacturing is agriculture. Within the framework of this study, using the PRODCOM statistical list, which provides statistics on the production value of manufactured products, an assessment of manufacturing involving biomass processing utilizing biomass from the agricultural sector in countries of the BIOEAST initiative was performed. In BIOEAST Initiative countries, biomass from agriculture is predominantly used by the food production sector, followed by economic sectors, such as beverages, textiles, leather and wearing apparel. In several BIOEAST initiative countries, the percentage of the production value utilizing biomass from the agricultural sector is remarkable. Poland is one of those countries for which the value of manufacturing production utilizing agricultural biomass represents almost 30% of the total manufacturing value. The results obtained from the analysis, along with detailed information on specific product groups, can provide valuable information for decision makers planning the development of the bioeconomy in reviewed BIOEAST countries, including Poland.

Maestri looks at how Italian experiences of migration to Australia inform artistic practices and, at the same time, how Italian Australian artworks visually translate mobility and migrant routes across the world. She focuses on the artistic career and productions of Melbourne-based second-generation migrant Jon Cattapan. Her analysis shows how his visual artwork can be read as a diasporic narrative and optical reflection on the added value provided by migration to the physiognomy and morphology of the city’s linguistic landscape. It asks how his art displays imaginary journeys across generations, ethnicities, and boundaries, and how it translates discourses of mobility and movement. The chapter aims to respond to the need to study constructions of Italianness in the face of constant reshaping of transcultural spaces and multimodal connections.

In the present study impact of structural variations on pre-hollow/micro-porous yarn's tensile and physical properties were investigated in view of their processing and ultimate product quality. The results show that: the core pre-hollow yarns and doubled pre-hollow yarns possessing continuous polyvinyl alcohol (PVA) filaments are better in tensile behavior than blended pre-hollow yarns which contain discrete PVA staple fibers. The doubled pre-hollow yarns were found to have the lowest unevenness, thick places, thin places and total imperfections followed by blended pre-hollow and core pre-hollow yarns, while blended pre-hollow yarns showed lowest number of neps. The core pre-hollow yarns exhibit lowest hairiness followed by blended pre-hollow yarns and doubled pre-hollow yarns. Use of double roving during spinning is beneficial for improving yarn strength, unevenness imperfections and hairiness in all the pre-hollow yarns.

This paper describes the result of investigating volcanic ash of Mount Kelud as fly ash substitute material to produce geopolymer concrete. The test was held on geopolymer concrete blended with 0%, 25%, 50% and 100% fly ash replacement with volcanic ash. Natrium Hidroxide (NaOH) with concentration of 12 molar and Natrium Silicate (Na2SiO3) were used as alkaline activator. While alkali-activator ratio of 2 was used in this research. The physical properties was tested by porosity and setting time test, while split tensile strength presented to measure brittle caracteristic of geopolymer concrete. The result shown that increasing volcanic ash content in the mixture will increase setting time of geopolymer paste. On the other hand increasing volcanic ash content will reduce split tensile strength and porosity of geopolymer concrete. After all replacing fly ash with volcanic ash was suitable from 25% to 50% due to its optimum physical and mechanical properties.

A CFD model of a HATZ diesel engine was developed for the purpose of simulating low temperature combustion (LTC) of surrogate diesel fuels for the Fuels for Advanced Combustion Engines (FACE). Initial validation of the model was performed using n-heptane data from a single cylinder HATZ diesel engine. Simulations were run with both a detailed n-heptane mechanism and several reduced mechanisms to determine the suitability of using a reduced mechanism to capture the main ignition characteristics and emissions. It was found that a 173 species n-heptane mechanism predicts start of combustion (SOC) within 0.5 crank angle degrees of the detailed 561 species mechanism. The 173 species mechanism required 27 hours of computational time to reach the end of the simulation whereas the 561 species detailed mechanism required 41 hours under the same conditions. Two additional reduced mechanisms, containing 85 and 35 species, were provided reasonable accuracy with a computational time of 8 hours and 2 hours, respectively. Due to the varying physical and chemical properties of the FACE surrogates, a sensitivity analysis of the effects of the physical properties was conducted by changing the n-heptane physical properties to those of n-hexadecane while keeping the chemistry the same. As expected, when the fuel properties of n-hexadecane (which is less volatile than n-heptane) were used with the n-heptane kinetics, SOC was delayed and the net heat release rate was reduced. The FACE fuels were developed to fulfill the need for research grade fuels that are able to represent common refinery stream fuels. Since the FACE fuels consist of hundreds of fuel components, it is not feasible to model the actual FACE fuels in a full-scale engine model. An alternative is to develop surrogates consisting of relatively few species for which detailed mechanisms are available. Even then this mechanism would need to be reduced to make the computation practical. For this work, a detailed diesel surrogate mechanism was reduced from 4016 species to 1046 species to match the characteristics for FACE fuels 1, 3, 5, 8, and 9. The surrogates only contain 4–7 species. Using the single chemical mechanism to represent five surrogate FACE fuels, it was found that ∼200°C of air preheat was required to achieve autoignition in the HATZ model compared to the 130°C of air preheat required experimentally. Initial runs have found that there were similar trends in SOC and heat release between the FACE fuel surrogate experiments and simulations for the respective fuels. Future work will require improvements on the single chemical mechanism to represent the five surrogate FACE fuels.

In the preparation of theophylline cocrystals, phenol coformers facilitate water assimilation due to their weaker O–H⋯N(imidazole) synthon. The presence of –COOH prevents water incorporation and provides added physical stability at high humidity. This study shows the feasibility of cocrystal design of an API to tune physical properties based on hydrogen bond synthons.

This main objective of this article is defining capacity of small business to act as compensator of negative trends, emerging in sphere of employment in large and medium sized business of Ukrainian economy. Authors are focused not only on the availability of working places created in small business for persons, vacated from large and medium sized enterprises, but on the small business capacity to create economic preconditions for improving qualitative characteristics of employment in this sector and in whole economy. Authors have built the multiplicative term, which expresses impact, caused by different characteristics of economic activity in small and large and medium sized business on the payroll dynamics as main indicator of economic potential for improvement characteristics of employment in appropriate economy’s sector. The first factor — is the total number of enterprises, as the expression of entrepreneurs’ economic activity and their preference to working in the official (registered) sector of the national economy. Second factor — is the average number of employees in enterprise of certain sector, as the expression of scale of resources, accumulated by average entity for economic activity. Third, the scale of output, created by unit employee in certain sector, as the expression of productivity level of labor resource, involved in this sector. Fourth, the volume of payroll is affected by the distribution of total output (which was used for estimation of labor productivity) between different directions of productive consumption, i.e. the share of payroll in the total revenue of small enterprises. The results obtained by factors analysis didn’t prove the thesis about small business capacity to compensate the negative trends, observed concerning employment in sectors of large and middle business of Ukrainian economy. The trends prevailing in creation and distribution of added value in small business does not contribute to improvement of quantitative and qualitative characteristics of employment in small business and whole Ukrainian economy. This situation indicates that small businesses in the face of negative macroeconomic dynamics have been unable to accumulate resources (at least by concentrating resources on fewer businesses that will be able to ensure higher efficiency) needed to improve the impact of the small business sector on the reproduction of employment in the economy of Ukraine. In addition, the significant lag in the level of wages in small business from large and medium and from the average level of the economy remains an important element of the mechanism for reproducing the low level of wages in Ukraine.

Moringa Leaf Extract

The development of topical dosage forms of Moringa leaf extract cream has been carried out because of its properties that can moisturize the skin. A pharamceutical preparation must meet the requirements of stability and non toxic. The study aimed to determine the effect of variations un the concentration ethanol extract cream of Moringa leaf of physical stability and irritability. Ethanol extract of Moringa leaves was obtained by maceration method with 50% ethanol solvent. The extract was then formulated in the form of O/W base scarring with concentrations of 1% (F1), 3% (F2), and 5% (F3). Creams were evaluated for physical stability including mechanical tests (centrifugation) and physical stability at room temperature (25 ± 2oC) with parameters pH, viscosity on days 1, 7, 14, 21 and 28. In addition, creams were also evaluated for their irritability in vivo with using test animals (rabbits). The data obtained were analyzed using one-way ANOVA test. The results of the physical stability test showed that an increase in the concentration of Moringa leaf extract caused an increase in viscosity (P <0.5) and a decrease in pH (P <0.5) but did not affect physical stability (mechanical test) and its irritating effect. F2 (1%) has a pH of 7.61 while F4 (5%) is 7.01. Based on the results of the study, it is concluded that variations in the concentration of ethanol extract of Moringa leaves can affect the physical stability of the cream and do not affect its irritation properties. Moringa leaf ethanol extract cream with a concentration of 5% (F4) has physical stability and does not irritate the skin better than other formulas.
