Grain drying is one of the most important steps of postharvest handling, appearing as the main preservation method due to its proven flexibility, technology and reliability.1 This process is employed with the main objective of reducing the grain water content to appropriate preservation levels, comprising simultaneous heat and mass transfers between drying air and grain, in such way that the product reaches an equilibrium condition considered suitable for preserving its physical, physiological and nutritious features.2,3 Among the artificial drying methods, the high-temperature drying appears as the fastest, less energy consuming and less dependent on local climate.4,5 Although not commonly used in less developed regions due to its high initial investment, this drying technique is desirable in many industrial processes, such as in wet rice drying since it can be beneficial to the cooking quality of this product, as well as in feed industry because high temperatures tend to enhance corn starch digestibility.6

This article addresses some relevant features of the Italian city of Rovigo, located in the Northeastern Italy’s Veneto region. Unable to compete with the nearby cities of Venice, Padua and Ferrara in terms of art and culture in general, Rovigo ended up victim of an unfair judgement expressed in a couplet unfairly attributed to Dante Alighieri. The main goal of the following is to contribute to restore Rovigo’s reputation. The research was based not only in a reliable bibliography, but also in my personal explorations as traveller.

The aim of this research is for decreasing contaminants using alginate beads with activated carbon entrapped (AG-AC) by adsorption. Different sunset yellow FCF concentrations were prepared in the laboratory. The effect of the different parameters was studied (pH, contact time, adsorbent dose, stirring rate, and concentrations) on the removal processes. The results were analyzed according to the Langmuir, Temkin, Freundlich, and Dubinin-Radushkevich adsorption isotherms. The removal efficiency is more appropriate by the Langmuir isotherm. Sunset yellow FCF (10 ppm) percent removal efficiency is (86%) at pH 3 and 10 gL of the adsorbent dose for 30 min with a fixed stirring rate (100 rpm). The effect of different operating parameters was investigated using Linear regression analysis which occupies more than 97 % of the total of the variables affecting the removal process. Finally, I recommend using this technology for Removal of Sunset Yellow FCF.

Students in high school need to write bilingual academic texts for different purposes and communicative functions. It is common that they have not developed knowledge or skills required for this type of writing. For this reason, they request support in bilingual writing in academic texts, and also for personal communication in letters and in social networks. Bilingual writing is a source of controversy since the lack of interrelation between native and foreign languages is generally promoted, as well as the idea that translation harms or interferes language teaching. In contrast, Pegenaute1, Nord2 and Fredholm3 propose translation as a support for language learning. In bilingual recommendation, students carry out self-translation of their texts, with the possibility of rewriting them in both languages, in order to adjust writing through multiple resources.4 Popovič et al.,5–8 Jung9 contemplate self-translation as a topic of research, and they disagree with the idea that translation is an art only for experts.
高中学生需要写不同目的和交际功能的双语学术文章。很常见的是，他们没有发展出这种写作所需的知识或技能。因此，他们要求在学术文章中使用双语写作，以及在信件和社交网络中的个人交流方面得到支持。由于普遍提倡母语和外语之间缺乏相互关系，以及翻译损害或干扰语言教学的观点，双语写作是争议的来源。相比之下，Pegenaute1、Nord2和Fredholm3提出翻译是语言学习的一种支持。在双语推荐中，学生对自己的文章进行自我翻译，并有可能用两种语言重写，以便通过多种资源调整写作popovije et al.， 5-8 Jung9认为自我翻译是一个研究课题，他们不同意翻译是专家的艺术的观点。

The use of laundry detergents based on synthetic ingredients is not an old innovation. Since ancient times until World War I, people for washing their clothes used soaps that were produced by saponifying fats and oils into fatty acid salts. In 1931, for the first time, Dreft powder introduced to the world as a synthetic detergent in the US. In 1946, Tide came to be known as a new detergent by P&G, armed with the phosphate. In 1988, the same company produced for the first time in history of detergents, liquid detergent with color-safe bleach. For decades, powdered and liquid laundry detergents containing linear alkyl benzene sulfonates (LABS), sodium lauryl ether sulfate (SLES), sodium dodecyl sulfate (SDS), ether sulfates, and alcohol ethoxylates as surfactants, along with builders, enzymes, polymers, and possibly bleaches as additional active ingredients have been used to meet the household laundry needs. These formulations were designed to deal with different types of dirt and stains depended on water conditions at various countries and cities.1 Recently, significant efforts have been done to develop surfactants to be used in detergent industry. In commercial applications some of the surfactants such as α-sulfomethyl esters and alkyl polyglucosides (APGs) are known as newer materials. Some of the other materials, such as ethoxylated amines, alkanolamides, betaines, alkyldiphenyl, and oxide disulfonates, have been used for many years routinely in other industries. One of the mostly used surfactants which have been used in powdered detergent industry is believed to be linear alkylbenzene sulfonate known as LAS. This surfactant is an inexpensive and accessible ingredient that is effective on dirt but less so on greasy or oily stains. Hence, still, searching for raw materials with low cost, higher yields and most importantly searching for green methodologies in detergent industry is of prime importance.

The objective of this document is to analyze the importance of wildlife populations in the farms where livestock is carried out, with the purpose of linking the use of wild populations with the sustainability of livestock farms. Agricultural activities present stronger variations than the other sectors of the Mexican economy; therefore, livestock production is subject to several shocks that generate strong fluctuations in the stability of the sector. This instability increases the risk in agricultural production. Environmental risks generate uncertainty with potential losses of profits associated with the presence of uncertainty about the possible results, leading to the economic agents to take advantage of this situation or to cover themselves in case of eventual losses. The existence of risks explain the defensive behavior of some farmers, such as the reluctance to modify the harvested methods or the use of new or innovative diversified systems, which do not seem optimal from the point of view of profitability.1 Changes in economics growth in the agriculture and livestock subsectors between the years 2012 to 20172,3 are shown in Figure 1. However, it is important to focus attention to alternative activities to diversify livestock production, whose aim would be: To reduce the vulnerability of the farm when the environment and the economy are unstable; to optimize the use of natural resources of wild fauna and flora present in livestock farms, through the generation of alternative products or services; to take advantage of opportunities for the use of wildlife, according to public policies that are governed by the binary principle of Conservation and Use.4

Goats were introduced to Mexico by the Spaniards during the conquest in the sixteenth century. The main breeds that arrived the country and gave rise to the Mexican Creole goat were the White Celtiberica, the Murciana and the Granadina.1 The “Creole” of this cattle was probably due to the isolation, the main force of several geographically different local goat populations. A well-marked situation in the country, while further south the frequency of pure Creole flocks increases.1,2 The morpho-structural characteristics of the mexican Creole goats are differentiated by two types of animals: small (25-32 kg and 60 cm of height at the cross in adult goats) in the center and southwest of the country, and medium (30-40 kg in adults goats) in arid and semi-arid regions of the country.3,4 On the other hand, the characteristics of Creole goats from Central America (smaller size, 28kg, 71 cm thoracic circumference and 64 cm height at the cross)5 are smaller than those of Mexico and the Caribbean (18.2-34.4 kg and height at the cross 50 cm).6 However, due to the lack of information of their origin, reproductive management, genotypic and phenotypic characterization; isn’t possible to differentiate the genetic composition of the goats flocks.7 In developing countries like Mexico it’s necessary to design reproductive and genetic improvement programs more efficient where genetic differences are involved between populations of production systems, this will allow to decide which genotypes introduce to the flocks to make them more efficient.2,8
