In the formulation of dried sweet sausage, pork meat and fat are traditionally used, which can be replaced by healthy products such as pecans (Carya illinoinensis) and kañiwa (Chenopodium pallidicaule); as well as llama meat (Lama glama) that is low in fat and cholesterol. For this reason, the present investigation aimed to optimize a formulation of dried sweet sausage considering three main components: llama meat, kañiwa flour and pecans. The D-Optimal mixture design method of the Design-Expert®7 program was applied, obtaining fourteen formulations. For each formulation, color, water activity and texture profile were evaluated. Only the cohesiveness fit a meaningful mathematical model. Subsequently, the optimization of the variable response was carried out, using the desirability function of the "objective value" type, so that the product could resemble the target (sausage made with pork meat and fat). In the sensory analysis of the optimal formulation, four sensory attributes were evaluated: color, odor, taste and texture, in a Z test to demonstrate whether the sample mean of the degree of satisfaction for each attribute of the product was acceptable or not. All these attributes are believed to be above the population mean taken as a target. In conclusion, the optimal formula was composed of 80% llama meat and 20% pecans, observing that kañiwa flour did not improve the texture and color of the sausage.

Background : Atorvastatin (AT), as a synthetic lipid-lowering agent, is a highly crystalline substance having poor solubility and low bioavailability. The objective of the present research was to improve the microprecipitation method of AT suspension preparation. Methods: Microprecipitation parameters were improved using Box-Behnken experimental design method. The suspension was formulated with Brij 35 (stabilizer agent) using methanol as solvent and water as non-solvent, respectively. DSC, XRD, FTIR studies were performed for characterization of the microcrystals. With the aim of evaluating the effect of independent variables, the amounts of organic solvent (X1), emulsifier concentration (X2), stirring rate (X3), and volume of aqueous solvent (X4) on dependent variables, drug content (DC,) particle size (PS), drug released after 5 minutes (Q5), Gibbs free energy change (ΔG°tr), crystal yield (CY) and saturated solubility (Ss), a full factorial was used. Results: The results of DSC, XRD, and FTIR showed that there was not any interaction between AT and Brij 35. This research demonstrated a reduction in crystallinity in agglomerates. The microcrystals showed that micromeritics characteristics were significantly improved compared to pure AT. The content of drug and yield crystal was in the limit of 42.58-110.24% and 58.33-98.18% in all formulations, respectively. It was shown that the prepared microcrystals had a higher rate of release compared to the untreated AT powder (P< 0.05). Size reduction of AT is needed for improving the solubility. Solubility and drug release rates of At was enhanced with the microprecipitation method. Conclusion: The results showed that microcrystals significantly increased AT dissolution rate.

Abstract To evaluate the differences in the characteristics of extracellular polymeric substances (EPS) secreted by Mycobacterium gilvum SN12 (M.g. SN12) cultured on pyrene (Pyr) and benzo[a]pyrene (BaP) , heating method was used to extract EPS from M.g. SN12, and the composition, emulsifying activity and morphology of EPS extracts were investigated in this study. It was indicated that EPS extracts varied significantly with the addition of Pyr or BaP to the bacterial cultures. Concentration of proteins and carbohydrates, the main components of the EPS extracts, first increased and then decreased, with an increase in the concentration of Pyr (0–120 mg L-1) and BaP (0–120 mg L-1). A similar trend was observed for the emulsifying activity of the EPS extracts. EPS extracted from all cultures exhibited a compact structure with smooth surface, except EPS extracted from BaP-grown M.g. SN12, which exhibited a more fragile and softer surface. These findings suggest that Pyr and BaP had different influence on the properties of isolated EPS, providing insights into the mechanism underlying PAH biodegradation by some bacteria secreting EPS. To the best of our knowledge, this is the first report on the texture profile of EPS samples extracted from M.g. SN12 grown on PAHs.

The array structure is widely used in precise electronic products such as large phased array antennas and large optical telescopes, the main components of which are a large surface base and a large number of high-precision discrete elements mounted on the surface base. The geometric error of discrete elements is inevitable in the manufacturing process and will seriously degrade the product performance. To deal with the tolerance design of discrete elements, a region-division-based tolerance design method is proposed in this paper. The whole array was divided into several regions by our method and the tolerance of discrete elements was correlated with the region importance on the performance. The method specifically includes the following steps: first, the sensitivity of the product performance to geometric errors was analyzed and the statistical relationship between the performance and geometric errors was established. Then, based on the sensitivity matrix, the regional division scheme was developed, and the corresponding tolerance was optimized according to the established relationship function. Finally, the optimal tolerance was selected among the multiple solutions to achieve the best performance. Taking a large phased array as an example, a simulation experiment was performed to verify the effectiveness of the proposed method.

The technological entrepreneurship ecosystem is a complex set of components and relations that enable the creation and growth of new technology firms. This ecosystem should be clearly defined and evaluated in order to reach its proper establishment. The purpose of this research is twofold. The first is to propose the main components of technological entrepreneurship ecosystem (TEE) and the second is to present some important principles for developing a comprehensive measurement framework of this ecosystem. For the first aim, through the meta-synthesis method, we identified and analyzed 34 related sources that ended in twelve dimensions (governance, capital, culture, talent, etc.). For the second aim, we defined six criteria (complexity, type of measures, design method, etc.) and critically reviewed 18 principal measurement frameworks that can be associated with the TEE. The review implied specific features such as the need to cover all dimensions of the TEE, addressing both input and output indicators, and considering both opinion-based & fact-based measures for the TEE measurement framework.

Turbine Design

The solar chimney is a simple renewable energy source consisting of three main components, a solar collector, chimney and turbine. Air under the collector is heated by the greenhouse effect. This less dense air rises up a chimney at the collector centre and drives an electricity-generating turbine. The operation of a solar chimney power plant is simple but high component efficiencies are needed for successful operation. A turbine design based on the design requirements for a full-scale solar chimney power plant is presented. The design integrates the turbine with the chimney. It is proposed that the chimney base legs be offset radially to act as inlet guide vanes and introduce pre-whirl before the rotor to reduce the exit kinetic energy. A three-step turbine design method is presented. A free vortex analysis method is used to determine the major turbine dimensions. A matrix throughflow method predicts the flow path through the inlet guide vanes and rotor. Finally the blade profiles are design using an optimization scheme coupled to a surface vortex method to achieve blades of minimum chord and low drag. The proposed turbine design can extract over 80% of the power available in the flow.

Simple Notion

The content of this article is devoted to theoretical aspects of the study of the problems of welfare, the life quality and lifestyle of the population, which the author calls with one simple notion – the quality of life. The article contains certain elements of scientific novelty. In particular, the author establishes the main components of quality of life: economic, ecological, sociological and psychological. The article proves that all the components interact in the complex; none of them is prevail against other and cannot replace others. The article also clarified the structure of the category “quality of life”, which, on the one hand, indicates the ability to satisfy human needs, including the needs of society; on the other hand, shows the degree of satisfaction of the person’s own life. Such a dualistic approach to the concept of quality of life is, in the author’s opinion, the basis for the formation of the concept of quality of life based on objective and subjective assessments. This concept in the framework of the research has been classical, because, in fact, was formed because of century evolution of different theories and scientific approaches to problems of quality of life. The author characterizes the four historical phases, which formed four distinct approaches to understanding the level and quality of life. The author further discussed the material, quantitative and integrated approaches, as these approaches formed in scientific and theoretical terms and as independent academic schools. The article is a logical continuation of the research of the author on issues related to the quality of life of the population.
