Rainfall Optimization Algorithm (RFO) is a nature-inspired metaheuristic optimization algorithm. RFO mimics the movement of water drops generated during rainfall to optimize a function. The paper study new implementations for RFO to offer more reliable results. Moreover, it studies three restarting techniques that can be applied to the algorithm with multithreading. The different implementations for the RFO are benchmarked to test and verify the performance and accuracy of the solutions. The paper presents and compares the results using several multidimensional testing functions, as well as the visual behavior of the raindrops inside the benchmark functions. The results confirm that the movement of the artificial drops corresponds to the natural behavior of raindrops. The results also show the effectiveness of this behavior to minimize an optimization function and the advantages of parallel computing restarting techniques to improve the quality of the solutions.

[Purpose] How to prevent fake news without spoiling the freedom of speech is a growing concern among governments across the world. Some countries see legislation as being the best approach to counter fake news. In the legislation proposals, accountability is mostly placed on technology companies, but also individuals seem to have responsibility in the legislation of some countries. Some other governments see non-legislative means to counter fake news. But it’s a fact that countering fake news without compromising free speech is a high priority across governments in the world and a challenging task too. This paper investigates the India scenario and tries to list out other than legislation what other measures are required. [Methodology] This paper takes a survey of mitigation efforts in select countries. This survey is used to testify against similar efforts in India, if any and adopts comparative approach to understand where Indian efforts stand at. [Findings] From using fact-checking tools available online, finding the source, locating how many people viewed a particular story to check grammar and spelling, and developing a critical mindset; plenty of things become a critical means in fighting down fake news. Legislation alone is insufficient. Media literacy, public scrutiny, good citizenship, and education along with sensitive civil society require playing its significant part in India to fight fake news. In India, the policy is vague. It gives the government enormous power to surveillance in the name of fake news.

In this paper, we report the experience of a mathematics teacher educator, who is a mathematician, while teaching the Euclidean Division Algorithm Theorem in a Number Theory course for prospective mathematics teachers. Considering that the knowledge of a Mathematics teacher is specialized, from the perspective of the Mathematics Teachers' Specialised Knowledge model, we intended to identify which knowledge is mobilized when the teacher educator addresses this algebraic result. Some activities were conducted by the professor in an attempt to understand how the prospective teachers performed the division of integers before, during, and after knowing the theorem; our analysis focuses on these different moments. Regarding the prospective teachers' knowledge, it was possible to observe, primarily, knowledge related to procedures involving the algorithm. However, throughout the conducted activities, they were able to establish different connections concerning the Euclidean Division Algorithm Theorem. About the teacher educator, we emphasize that his mathematical and pedagogical knowledge, combined with the goal of effectively prepare future Mathematics teachers, has the potential to promote specialized knowledge in the prospective teachers regarding the subject matter.

Effective treatment of gestational diabetes is important as an attempt to avoid unfavorable maternal and fetal outcomes. The objective of this paper is to describe the available therapies to optimize gestational diabetes treatment and to suggest a multidisciplinary approach algorithm. Nutrition therapy is the first option for the majority of these pregnancies; light to moderate physical activity is recommended in the absence of obstetrical contraindications. Medical treatment is recommended if glycemic control is not achieved or if excessive fetal growth is detected by ultrasound. Insulin is the standard treatment although oral antidiabetic drugs have recently been considered an effective and safe option. The monitoring of gestational diabetes treatment includes capillary glucose measurements and evaluation of fetal abdominal circumference by ultrasound performed around the 28th gestational week.

The objective of this manuscript is to discuss the existing barriers for the dissemination of medical guidelines, and to present strategies that facilitate the adaptation of the recommendations into clinical practice. The literature shows that it usually takes several years until new scientific evidence is adopted in current practice, even when there is obvious impact in patients' morbidity and mortality. There are some examples where more than thirty years have elapsed since the first case reports about the use of a effective therapy were published until its utilization became routine. That is the case of fibrinolysis for the treatment of acute myocardial infarction. Some of the main barriers for the implementation of new recommendations are: the lack of knowledge of a new guideline, personal resistance to changes, uncertainty about the efficacy of the proposed recommendation, fear of potential side-effects, difficulties in remembering the recommendations, inexistence of institutional policies reinforcing the recommendation and even economical restrains. In order to overcome these barriers a strategy that involves a program with multiple tools is always the best. That must include the implementation of easy-to-use algorithms, continuous medical education materials and lectures, electronic or paper alerts, tools to facilitate evaluation and prescription, and periodic audits to show results to the practitioners involved in the process. It is also fundamental that the medical societies involved with the specific medical issue support the program for its scientific and ethical soundness. The creation of multidisciplinary committees in each institution and the inclusion of opinion leaders that have pro-active and lasting attitudes are the key-points for the program's success. In this manuscript we use as an example the implementation of a guideline for venous thromboembolism prophylaxis, but the concepts described here can be easily applied to any other guideline. Therefore, these concepts could be very useful for institutions and services that aim at quality improvement of patient care. Changes in current medical practice recommended by guidelines may take some time. However, if there is a broader participation of opinion leaders and the use of several tools listed here, they surely have a greater probability of reaching the main objectives: improvement in provided medical care and patient safety.

During the past years, the number of patients with both anaphylaxis to hymenoptera sting and negative IgE detected by conventional methods has been increasing. To obviate this problem new assays have been tried, such as Western blot and in vitro challenge tests involving basophil activation, with either the measurement of histamine and sulphidoleukotrien released (CAST--Cellular Antigen Stimulation Test) or the detection of activation markers on the cell surface with flow cytometric analysis (Flow CAST). In this paper the principles of these assays as well as their diagnostic value in hymenoptera allergy are briefly reviewed.

A problem in mass balance resolution in mineral processing plants is the circulation load in closed-circuits. A family of methods which can be used to solve the circulating load is the iterative methods. This paper shows a low complexity algorithm to calculate the circulation load in closed circuits which allows the construction of mass, metallurgic and water reliable balances. The proposed algorithm was validated against results from Caspeo BILCO software and real industrial data for two different closed-circuits types. The obtained results are satisfactory with respect to the calculated result, processing speed, solution convergence and number of iterations needed to evaluate the circulation load.

Our objective in this paper is to present and discuss the complexification of the process of platformization of journalism by Facebook, triggered by the implementation of the Facebook Journalism Project (FJP), in January 2017. Since then, the platform has been associating itself with new and varied actors, expanding its fronts and positioning itself as a coordinator of activities related to journalistic institutions. At the same time, it continued to offer itself as an infrastructure for the development of journalistic products and businesses. Based on the Platform Studies and methodologically inspired by the Cartography of Controversies, we present the FJP and public demonstrations by journalists, researchers and other actors involved in its implementation. The diversification of partnerships, the inclusion of pedagogical actions, the renegotiation of prescriptive and normative dimensions that guide journalistic institutions, and the consolidation of the platform as an infrastructure are the main issues discussed at the conclusions.
