The aim of the present work was to optimize the sensorial and technological features of ice cream. The experimental work was performed in two stages: 1) optimization of lactose enzymatic hydrolysis, and 2) optimization of the process and product. For the first stage a complete factorial design was developed, optimized using both response surface and the steepest ascent method. In the second stage a mixture design was performed, combining the process variables. The product with the best sensorial acceptance, high yield and low cost was selected. The acceptance of the product was developed by an untrained taster’s panel. As a main result the sensorial and technological features of the final product were improved, establishing the optimum parameters for its elaboration.

In this work we critically approach the figure of the illicit association from a double perspective: historical and constitutional, questioning its theoretical foundations and its jurisprudential use. We connect your employment with arbitrary criminal proceedings where procedural guarantees are usually violated. We recover its political history in times of witch hunts, when the term „subversive association“ is born, in times of persecution of the coven, taken by many contemporary historians (especially feminist as Silvia Federici) as forms of resistance to new forms of organization of rural property (since behind the witch hunt was the expansion of rural capitalism) or resistance to the privatization of land in Europe. We conclude, making a parallel with the witch hunt (political criminalization program), that the alternative to the constant and growing criminalization of marginaliz...

This study contributes to filling the existing gap in the scarce literature on school effectiveness in secondary education in Peru by addressing the following questions: i) which educational processes within schools are most influential in math and reading comprehension? and in the case of the most effective schools, ii) what is the importance that principals, teachers, and students place on school processes variables in explaining educational outcomes? We use a mixed-method design that follows a sequential explanatory design. First, using the Young Lives secondary school survey in Peru (2017), we estimate a random effects model to explore the effect of teacher and school level variables on math and reading comprehension. Then, we conduct a qualitative case study in two schools identified as high-performance schools (HPS) by the survey, with the aim of explaining the role of school proce...

“The most devastating disease to humanity is commonly known as elephantiasis. Infection usually acquired in childhood but visible indication like pain, disfiguring occur later in life. Severely affected people will have a permanent disability. Not only had it generated physical challenges it also cost for social, psychological, and economical losses. The impact of the disease is so painful and devastating among young men and women as they live with the lifelong disfiguring condition. As the parasite attacks directly to the lymphatic system of the body whose primary function is to drain all the harmful components and impurities from tissues and cells also make a strong immune system of the body to fight against infection and diseases. Since the parasite attack damages the lymphatic vessels and capillaries. Hence the effect is on the flow of lymph resulting in lymphoedema. 90% of the cas...

The implementation of any software development process involves the consumption of critical resources. Software engineers cannot experiment with different development processes before starting them in real projects, due to the time that would entail and the amount of elements that are involved, so it is vital to have tools that allow the pre-visualization of the results of executing the software development process and how the environmental variables affect it, thus being able to anticipate under what conditions the software development process will be deployed. This paper presents the modelling and simulation of a software development process using System Dynamics (SD), which allows the graphical representation of the elements intervening in the software process, and the incorporation of as many relevant elements as possible. As a software costs estimation reference, the COCOMO estimati...

The selection process of design team subcontractors by real estate companies is crucial in construction projects, directly affecting the quality and efficiency of the final results. However, the lack of time to evaluate potential subcontractors can lead to inadequate selection and negatively impact the project development. This study proposes an innovative approach to improve confidence in the selection processes of design team subcontractors in multifamily building projects by implementing Set Based Design (SBD) and Choosing by Advantages (CBA) methodologies. These methodologies, supported by Excel Macros programming and data visualization in Power BI, aim to automate and optimize the selection process, reducing human intervention. The study follows these steps: (1) information registration and analysis by experts, (2) determination of the conventional subcontract selection process in t...
