Aluminum Sulfate Wastewater Treatment Comparison - Bok av Yurka Fernández Gutiérrez - Häftad

Aluminum Sulfate Wastewater Treatment Comparison - Bok av Yurka Fernández Gutiérrez - Häftad

Within the primary treatment of wastewater, there are two interrelated processes: coagulation and flocculation; where the aim is to reduce the turbidity load, for which chemical additives called coagulants are used. The objective of this work was to determine the optimum doses and compare the turbidity removal efficiency and variation in pH level between a chemical coagulant aluminum sulfate and a biocoagulant obtained from tamarind remains. To evaluate the turbidity and pH parameters, the samples..

Numerical Modelling and Simulation of Fractals in C++ - Bok av Ph. D. Santos - Häftad

Numerical Modelling and Simulation of Fractals in C++ - Bok av Ph. D. Santos - Häftad

In Euclidean Geometry, the simplest and best known figures are studied, such as: straight lines, squares, circles, cones, pyramids, among others. In this context, many phenomena and shapes are found in nature, which cannot be explained in the conventional mathematical molds, requiring a special theory to explain and characterize them, known as fractal geometry. According to (TRICOT, 1955) fractal means \broken\, which are geometric shapes with some special characteristics that define and distinguish..

Sentiment analysis of X text with deep learning - Bok av Jessica Olivares López - Häftad

Sentiment analysis of X text with deep learning - Bok av Jessica Olivares López - Häftad

Sentiment analysis is one of the text classification applications of natural language processing, basically assigning an appropriate category to the content of a sentence, text or document, based on the (previously unstructured) text processing. This classification is done by assigning a sentiment polarity: positive, negative or neutral to a sentence or a document, or by assigning an emotion that is identified in the sentence.Sentiment analysis is currently a powerful tool in various applications..

Save the Ebrié Lagoon - Bok av Ane Maurice Aka - Häftad

The estuarine part of the Ebrié Lagoon is under enormous anthropogenic pressures and seasonal natural forcings. A monitoring of the evolution of its hydrology during the year 2014 revealed that it is strongly influenced by the lagoon seasons. Thus, salinity, pH, dis-sub oxygen, temperature and transparency are higher in low water season especially in the vicinity of the Vridi channel under strong marine influence (Biétri and Azito channel). Suspended solids are more abundant during the rainy season,..

The aim of this study was to determine the physical, physico-chemical and nutritional characteristics and cyanogenic potential of the flours of three of the most widely grown cassava cultivars in the DIANA Region. Materials and methods were used to achieve this objective. The results obtained showed that the flours of these three cassava cultivars have water contents of 10.69% (Menarevaka), 11.38% (Mena) and 11.53% (Fotsy). These flours have pH values of 6.03 (Menarevaka), 5.74 (Mena) and 6.04 (Fotsy)...

Secular State and the Presence of Religiosity - Bok av Joanita Kaleski - Häftad

A ponderation on the apparent Brazilian State laicity is presented here, demonstrating the influence of religious belief in the political-legislative sphere from a historical-constitutional perspective. The secular State has a neutral position in the religious field. Also known as the secular State, it preserves the principle of impartiality in religious matters, does not support or discriminate against any religion. It defends the religious freedom of all its own and does not allow the interference..

The Vatican and the DRC: Church and Politics - Bok av Vital Y. Mbumba - Häftad

A highly influential player on the international stage, the Holy See is a diplomatic power to be reckoned with. The Holy See's apostolic interests in the DRC are more important than its political interests. Vatican diplomacy is apparently neutral in the face of the antagonistic relationship between the local Catholic Church and Congolese political power. This is in line with the principles of non-interference and respect for state sovereignty that guide diplomatic relations between states, but also..

Chemistry of plant raw materials - Bok av Davronbek Urunov - Häftad

In the review the data on the use of enzymes of the peroxidase superfamily of plant and fungal origin as catalytic agents for the oxidation of lignin and its model compounds by hydrogen peroxide are considered. A comparative characterization of the structure and mechanism of catalytic action of these enzymes is given. Enzymes of peroxidase family of fungal and plant origin have similar structure, but higher stability and pH-optimum for plant peroxidases are noted. It is concluded that it is promising..

Cultural diversity and interbreeding - Bok av Rita El Khayat - Häftad

It is clear that the world is evolving at a speed that it has never recorded until recently; while going faster, the world is evolving towards a state of possible exchanges that are more and more numerous and ever increasing. These exchanges are neither neutral nor simple; they can be described and evaluated qualitatively, but it is difficult to quantify them, to predict their evolution, while knowing that they are inescapable: the global mass of world exchanges will increase irrepressibly. These..

Writing and survival in Letters from prison (Frei Betto) - Bok av Marcílio Godoi - Häftad

The search for a narrative. A story behind a set of apparently disconnected stories. A bundle of records that not only refers to the symbolic description of an important Brazilian historical period, but also, despite its incipient literary charge, to the trajectory that a man must necessarily trace in his crossing over the absurdity of the world, the movement of dynamic balance of the author's origin in the denial of death. Roland Barthes' concept of the Neutral provided the attribute of impasse..

Analysis: Carbon Neutrality and Implementation in Dentistry - Bok av María Alexandra Ramírez Garro - Häftad

The environmental issue has taken a lot of strength in recent years, we are in an era where the damage that humanity has done to the planet is becoming more noticeable. However, a large part of the population has begun to become aware and take action on this issue to begin to minimize the repercussions we have created. Costa Rica in particular wants to become a carbon neutral country within a few years so this research topic seemed very relevant to the current national reality. Similarly, the dental..
