Fireworks

Background: Fireworks related injuries in children occur in Kosovo particularly during New Year celebrations.Aim: To report the pattern of fireworks- related injuries in childrenup to 16 years of age treated at the Emergency Center and Plastic Surgery,University Clinical Centre of Kosovo during the 2008 and 2009 New Year celebrations.Methods: Retrospective review of hospital recordsResults: During the New Year celebrations in 2008, a total of 65 caseswere admitted, 32 (49.2%) of who were children injured by fireworks. The ages of the children ranged from 5 to 16 years with a mean of 10.5years. The modal age affected was the 10 – 14 year-old group (53.6%). Boys constituted 93.8% of patients and girls 6.3%. During the 2009 New Year celebration, 17 cases were admitted with fireworks injuries, 12 (70.58%) of who were children ranging in age from 8 to 15 years (mean 11.5 years) with a modal age group of 10 – 14 years (66.7%). Boys accounted for 88.3% and girls for 16.7% of patients.Concl...

Traumatic tattoos are undesirable tattoos caused by different foreign bodies such as fireworks' particles, sand, metals, glass, gunpowder, asphalt, dust, or petroleum products embedded forcefully in the dermis. We report the case of a 54-year-old man who presented with sand and asphalt tattooing on his face following a bomb explosion 15 years ago. Q-switched Nd:YAG laser at a wavelength of 1064 nm with a spot size of 4 mm and a fluence of 7.96 J/cm 2 were applied to treat the patient. The patient tolerated the treatment very well. Most of the blue dots became whitened immediately after the procedure and remained almost clear after a 6-month follow-up.

During religious feasts in the Teotihuacán and Texcoco regions northeast of Mexico City, people ‘dance for the saint,’ often to fulfill a vow made in a supplication for healing. Based on fieldwork carried out between 2011 and 2019, and online interviews and monitoring of Facebook postings in late 2020 and early 2021, in this article we explore the impact of the coronavirus on the devotional dances staged in the context of religious feasts. In particular, we examine the cases of new practices adopted during the lockdown. Drawing on Jeremy Stolow’s (2005) concept of “religions as media,” we show how a combination of digital and in-person media make it possible for local Catholic communities to maintain the relationship with their patron-saint during the pandemic, based on the principle of do ut des, “though differently.” We conclude by raising questions concerning the future of the devotional dances and religious feasts in these regions as pandemic restrictions entered their second year.

According to Seveso Directive the analysis of accident and near miss has be performed in order to identify which elements of the safety management system (SMS) should be reviewed. In this paper, a real accident in a chemical depot has been analyzed to investigate which aspects of safety management system should be improved. Both occupational safety and health (OSH) aspect and major accident hazards (MAH) about the accident have been considered by using two specific methods: the Infor.Mo. and the Root Cause Analysis. A comparison between the results obtained by application of two methods has been made to individuate useful information about occupational and major accident aspects and to harmonize them in a SMS. 1.1 MAH and OSH harmonization The general approach to study accidents has changed over time; in fact, compared to a negative attitude to cover up the truth that has caused an increase in the frequency of accidents, it has been recognized the need for accident forecasting, consequences assessment and development of up-to-date emergency preparedness and disaster management plans (Khan, 1999). Surely benefits are evident by the adoption of an SMS in all industrial sectors especially in the beginning, when, to implement management system, the working procedures are documented and the roles within the organization are defined (Bottani et al., 2009). Interesting studies are related to the investigation between injuries and accident or in general between OSH and MAH. The most recent papers include Bellamy et al. (2013), which investigated 118 recorded incidents and accidents at establishments subjected to Seveso Directive in Netherlands, Bellamy et al. (2014), which analyzed some 20.000 occupational injuries and Lisbona et al. (2012) which examined a dataset of 975 incidents. Furthermore, it should be considered studies of OSH' risks in Seveso establishments where the focus is on technical system such equipment, devises and control. As discussed by Bragatto et al. (2015) SMS-MAH is usually integrated with SMS-OSH and reflects the same structure; but it is more demanding because the extent of accidents is much larger, the consequences much more severe and the control by authorities compelling. The authors stressed this aspects about small and medium sized enterprises end consider that the "real" safety system is made by equipment, materials, instruments, instructions, procedures, documents, plans and workers with their knowledge and experience. Agnello (2013) makes a comparison between occupational Regulation (Italian Decree 81/08) and major accident Regulation (Italian Decree 334/99 now abrogated and replaced by Decree 105/2015). The report shows that health and safety Regulations have a point of view defined person-centric, as it is based on protection of worker, while major accident control

The burning of fireworks damages air quality by causing elevated concentrations of particulate matter (PM2.5 and PM10) in short periods of time. In this context, the research aimed to compare airborne concentrations of PM2.5 and PM10 from fireworks with the National Ambient Air Quality Standards (NAAQS) and the World Health Organization (WHO) guideline. The applied methodology involved the use of the PRISMA 2020 statement. The literature review was conducted on digital databases such as Scopus, ScienceDirect, Taylor & Francis, Wiley, and Ebsco. Annual growth in scientific production was calculated using a digital tool (Calcuvio), and data analysis was performed using Microsoft Office Excel and VOSviewer. The annual growth in production (1999 to 2022) was 18.74%. The highest scientific production per year was concentrated in 2019 and 2020, with China being the leading country. The festivities where sound pressure levels were predominantly measured were during the Spring Festival and Diwali. The most frequently mentioned keywords were "fireworks" and "PM2.5". In conclusion, the percentage of studies that exceeded the NAAQS for PM2.5 and PM10 was 2% and 15%, respectively, while for the WHO guideline, it was only 1% for PM10.

Il s'agit bien d'un essai, avec tout ce que la tentative induit de lacunaire : l'exhaustivité, particulièrement à propos de Le Moyne, est chose improbable, en l'absence d'une monographie actualisée sur cet auteur. Nous espérons seulement fournir un point de départ aussi commode que possible à qui voudrait s'engager dans une recherche plus approfondie sur tel ou tel aspect, ou de l'oeuvre, ou de l'homme. La partie « Sources » a seulement vocation d'aide-mémoire. Elle récapitule les écrits imprimés du jésuite dans leur ordre chronologique et signale uniquement les premières éditions ; elle ne tient pas compte des traductions et ne détaille pas les pièces contenues dans les recueils. Reprendre à nouveaux frais les recensements établis dans la Bibliothèque des écrivains de la Compagnie de Jésus et dans l'ouvrage d'H. Chérot, ainsi que les corrections apportées ponctuellement par telle ou telle étude postérieure, excéderait le cadre présent d'une livraison de revue, d'autant que le lecteur trouvera pour Les Triomphes de Louis le Juste et les Entretiens et lettres poétiques de précieuses informations dans les notes des articles de Stéphane Macé et de Richard Maber. La partie « Bibliographie critique » signale les références exploitées dans les articles de ce numéro, alors abrégées en notes de bas de page. S'y ajoutent les mentions d'autres études consacrées même partiellement à Le Moyne, de manière à compléter l'information.

The variation in air quality was assessed from the ambient concentrations of various air pollutants [total suspended particle (TSP), particulate matter ≤10 μm (PM 10), SO 2 , and NO 2 ] for pre-Diwali, Diwali festival, post-Diwali, and foggy day (October, November, and December), Delhi (India), from 2002 to 2007. The extensive use of fireworks was found to be related to shortterm variation in air quality. During the festival, TSP is almost of the same order as compared to the concentration at an industrial site in Delhi in all the years. However, the concentrations of PM 10 , SO 2 , and NO 2 increased two to six times during the Diwali period when compared to the data reported for an industrial site. Similar trend was observed when the concentrations of pollutants were compared with values obtained for a typical foggy day each year in December. The levels of these pollutants observed during Diwali were found to be higher due to adverse meteorological conditions, i.e., decrease in 24 h average

The effects of a Summer Firework Festival on the air quality were studied for the first time in a rural area of Southern Italy. The case study analyzes the physical-chemical properties of airborne particles collected during the Note di Fuoco (NDF) Festival, which took place in Belvedere M.mo in 2016. The sampling period was peculiar since in one week three different kinds of events have succeeded: three days during the NDF Festival with the concurrence of the festival and the firework displays, one day with the typical street Market involving food stalls and specialty shops, and three days with no specific events, considered as background conditions. Particulate Matter in different two size fractions (PM 2.5 and PM 10) was simultaneously collected on a daily basis and then chemically analyzed for major and trace metal content as well as for organic and elemental carbon determination. Levels of particles were even below the European air quality limit values. However, the day with the country market and during the three days of the NDF festival, the finer and respirable particulate fraction, PM 2.5 , showed an increase of 46% and 84%, respectively, over the mean concentration values observed during the background days. Both elemental and organic carbon, even in the finer fraction showed an increment up to 30%. All major, and trace elements were found in higher concentrations during the festival with respect to those recorded in days with no events. In our case study, K was recognized as the best fireworks tracer because its level doubled during the festival. Typical firework tracers like Fe, Ti, Mn, Pb and Sr resulted in greater concentrations, up to 50%.

As a revolutionary swarm intelligence algorithm, fireworks algorithm (FWA) is designed to solve optimization problems. In this paper, the dynamic fireworks algorithm with covariance mutation (dynFWACM) is proposed. After applying the explosion operator, the mutation operator is introduced, which calculates the mean value and covariance matrix of the better sparks and produces sparks according with Gaussian distribution. DynFWACM is compared with the most advanced fireworks algorithms to proof its effectiveness. In addition, 15 functions of CEC 2015 competition on learning based realparameter single objective optimization are used to test the performance of our new proposed algorithm. The experimental results show that dynFWACM outperforms both AFWA and dynFWA, as well as the experimental results of the 15 functions given.

Since fireworks algorithm (FWA) debuted in 2010, a dozen proposals of improvement for FWA had been published in an effort to enhance, refine and optimize accuracy while minimizing calculation speed and volume. In this paper, we introduce the covariance mutation operator into cooperative framework fireworks algorithm (CoFFWA) to create cooperative framework fireworks algorithm with covariance mutation (CoFFWA-CM) in order to solve the Congress on Evolutionary Computation (CEC 2016) competition functions on single objective optimization. The experimental results are calculated on all 10-, 30-, 50-and 100dimensional functions.

The present study assesses the construction dust pollution scenario and associated health risks for construction sites in the Kolkata metropolis. The generated PM levels well exceeded the daily and annual National Ambient Air Quality Standards (NAAQS) of India (214.78-12 202.28 and 424.64-20 403.81%, respectively for PM10 and 182.20-5847.92 and 323.29-8821.88%, respectively for PM2.5). Mortality risks associated with long-term exposure to such high PM levels are estimated for construction workers. The stochastic nature of the influencing variables while calculating health risks is handled through the Monte Carlo Simulation (MCS). The mortality risks for different causes due to elevated PM10 exposure (RR_Expos_PM10) ranged between 1.25 (±1.20) for the risk of stroke for earthwork workers to 75.89 (±46.87) for the risk of chronic obstructive pulmonary disease (COPD) for brick wall-cutting workers. The mortality risks for PM2.5 exposure (RR_Expos_PM2.5) ranged between 1.96 (±0.40) for the risk of non-malignant respiratory diseases for earthwork workers to 19.04
(±8.82) for the risk of acute lower respiratory infections (ALRI) for brick wall-cutting workers. A sensitivity analysis was also carried out, which showed that the mortality risk associated with PM10 and PM2.5 exposure is most sensitive to the PM10 concentration during construction activities and pooled relative risk for PM2.5.
The mortality risk of exposed construction workers was alarmingly higher (14.68-3548.56% higher for PM10 and 61.60-1269.78% higher for PM2.5) than the average Kolkata City population. Policy-level and site-level interventions are necessary to control and mitigate the alarming scenario.

This paper presents a cooperative hybrid algorithm based-on twometaheuristics: Fireworks and Differential Evolution. The main ideais to randomly choose which metaheuristic will be used on eachiteration during the optimization process. We adopted the Rosenbrockfunction in our preliminary experiments. It is a challengingfunction to optimize because it is multimodal and non-separablewhen solving it in more than three dimensions. The initial investigationsshow that the hybrid algorithm tends to present betterresults than the canonical ones.

The wood carving on the hilt and sheath (taguban) of parang (machete) created by the Bajau craftsmanship in Kota Belud is well-known for its uniqueness across Sabah. This study discusses the stylisation and value of appreciation from the philosophy of Bajau's craftsmanship and the influence of the wood carving motif designs. The subject of birds is interpreted as a pattern in wood carving on either on the hilt, the tagubantaguban (sheath) or bladed weapon. Among the examples of bird's subjects include hornbills, birds, manuk (rooster) and naga (dragons). This study aims to comprehend Bajau's parang weapons, addressing the bird's motif and its connection to mythical and cosmological values and why the study of the values expressed Bajau craftsmanship concerning the principles of Malay aesthetics as it expands the cultural reach of the Bajaus across the Malay Archipelago. This research is conducted through in-depth interviews with Bajau parang craftsmen as well as through participant observation at their workshop and exhibitions. Semantic Differential method is used in the research to understand what the larger community of Bajau craftsmen recognise to be the values inherent in their artform. The authors refer to Zakaria Ali's six principles of Malay aesthetics to understand how the parang-wood carving traditions of the Bajau conform to these principles. It is within this early cosmopolitan history that the bird design motif can be understood as a motif that embodies both local

Zusammenfassung Hintergrund und Ziel Die kontinuierliche Erfassung von Augenverletzungen durch Pyrotechnik in den Tagen um Silvester über 6 Jahre ermöglicht uns, Verletzungszahlen, Verletzungsmuster und Unfallhergänge im Jahresvergleich zu untersuchen. Zur Entlastung der Krankenhäuser wurden in Deutschland im Rahmen der COVID-19-Pandemie für die Jahreswechsel 2020/21 und 2021/22 ein Verkaufsverbot für Pyrotechnikartikel und Versammlungsbegrenzungen umgesetzt. Wir untersuchen, welchen Einfluss diese Maßnahmen auf die Anzahl von feuerwerksbedingten Augenverletzungen hatten. Außerdem betrachten wir, ob dies zu einer Zunahme schwerer Verletzungen geführt hat und ob ein Zusammenhang mit einer vermehrten Nutzung selbst gebauter oder in Deutschland nicht zugelassener Pyrotechnik bestehen könnte. Methoden Mit unserem Online-Fragenbogen erfassen wir anonymisierte Daten zu Patienten, Unfallhergang und seit 2017/18 auch zur Beschaffung der eingesetzten Pyrotechnikartikel.

La flèche est un élément graphique très utilisé sur les écrans informatiques : pointeurs, ascenseurs et autres curseurs font appel à elle. Pourtant c'est un signe dont la lecture et l'interprétation font appel à des codes socio-culturels forts. Une flèche désigne, indique une direction, transperce… Le choix de ce type de représentation n'est pas neutre. L'étude présentée dans cette communication s'attache à montrer tout d'abord en quoi la flèche détermine la place et le rôle de l'utilisateur dans le dispositif. L'observation de professionnels du montage vidéo permet ensuite de montrer comment ce choix est compris par le professionnel et comment il interprète ce signe dans différents contextes au cours de son travail de montage.

Although most research related to urban noise exposure, refers mainly to transportation noise, epidemiological research has already demonstrated the risks of leisure noise exposure, including fireworks, on children, the youth, and young adults thus denoting the need for further investigation. Cumulatively, the general population living near an event's location can also feel disturbed by this type of noise. This study investigated the noise produced by fireworks at events not yet evaluated, indicating the need for better noise management by the organizers, as well as a revision of the recent European Directive in addressing exposure limits for children. The objective of this study was to evaluate the noise exposure of the population of Northern Portugal during fireworks at festivals and pilgrimages. With that purpose, measurements and questionnaires were conducted at 27 non-pyromusical and pyromusical events. Events considered to be the largest or the most traditional events which occur annually in the Northern Region of Portugal. The measurement equipment was a type 1 sound level meter, from 01 dB, positioned at the most exposed point, meaning, the area where the population was closest to the fireworks. The measurement time lasted for the entire duration of the firework explosions. The L Aeq , L Amin , L Amax values, as well as the statistical indicators, L A90 , L A50 , and L A10 , were determined with an impulsive response. The results showed that in 72% of the evaluated events, the exposure level exceeded 120 dB (A, imp), the limit-value defined by the Directive 2013/29 UE. The average L Amax , CI 95% value, for the exposed population when assisting those events, ranged between 121 and 125 120 dB (A, imp). Hypothesis tests performed for this sample, at a significance level of 5%, demonstrated that there is no significant difference between the average exposure for both types of events, nonpyromusical and pyromusical. Considering that these noise levels can induce hearing impairment this study demonstrated the need for noise control measures for the people attending these types of events. Suggested solutions highlight the following safety measures: the use of quiet fireworks, the reduction of music volume at pyromusical events, changes to the public's position and an implementation of public sessions in order to raise the population's awareness about harmful noise effects, particularly for groups that are more sensitive to noise.

Que imagens nos transmitem tantas lembranças quanto às celebrações junto aos nossos entes e amigos queridos? Dentre as lembranças, certamente estão as das festas juninas. A reunião em família, as comidas típicas, a fogueira acesa e as crianças encantadas com pequenas estrelas derramadas de suas mãos. Partindo dessas imagens, decidimos ingressar em um mundo nostálgico, pois, segundo Gaston Bachelard (1999:11), “o fogo e o calor nos fornecem meios de explicação nos domínios mais diversos, porque é, para nós, a ocasião de lembranças imperecíveis, de experiências pessoais simples e decisivas”.

Este artículo presenta los resultados de una investigación cualitativa sobre las significaciones que el acto de cantar canciones de cuna posee para madres de la provincia del Elqui en la región de Coquimbo, Chile. Nuestro principal objetivo fue dilucidar las ideas respecto a las funciones que ha cumplido este canto en las propias vidas de las madres y cómo estas significan dicha práctica musical. A partir de entrevistas y grupos de discusión buscamos develar propósitos más profundos del cantar canciones de cuna, los que trascienden la mera intención de calmar y ayudar a dormir.

Two to three weeks after the explosion of a fireworks storage facility in a residential area (May 2000, Enschede, The Netherlands) we assessed the self-reported physical and mental health among those affected by the disaster. Methods: A questionnaire survey was conducted among 3792 residents, passers-by, and rescue workers, who were involved in and/or affected by the disaster and were $18 years of age. Results: At least 30% of those affected by the disaster reported serious physical and mental health problems 2-3 weeks after the explosion. Compared with reference values in the general Dutch population, high scores were found for somatic symptoms, sleeping problems, and restrictions in daily functioning due to physical and mental problems, such as anxiety, depression, and feelings of insufficiency. The strength of these differences varied between groups, based on the level of involvement and the level of being affected. Conclusions: Results indicate that the fireworks disaster had a substantial impact on the health of those affected by the disaster. The health impact was most pronounced for residents and passers-by and also for rescue workers living in the affected area, but to a lesser degree. Physical and mental health problems were strongly associated with the shocking experiences during and shortly after the disaster.

Celebrating the new year with fireworks is traditional in Italy. A national surveillance system maintained by police indicated that on New Year&#39;s Eve 1992, more than 1100 fireworks-related injuries and four deaths occurred in Italy (Ministry of the Interior, unpublished data, 1993). In many areas of the country, the use of fireworks begins several weeks before the new year and continues through the Epiphany (January 6). To characterize fireworks-related injuries in the province of Naples--an area that contains less than 6% of the total population of Italy but accounts for 15% of the reported fireworks-related injuries in the country--the Regional Health Observatory of Campania and the Italian field epidemiology training program implemented an active surveillance system in each of the 18 public emergency rooms (ERs) in the province (1992 population: 3.5 million). This report summarizes surveillance results for the new year period 1992-93.

In the present Anthropocene, wild animals are globally affected by human activity. Consumer fireworks during New Year (NY) are widely distributed in W-Europe and cause strong disturbances that are known to incur stress responses in animals. We analyzed GPS tracks of 347 wild migratory geese of four species during eight NYs quantifying the effects of fireworks on individuals. We show that, in parallel with particulate matter increases, during the night of NY geese flew on average 5-16 km further and 40-150 m higher, and more often shifted to new roost sites than on previous nights. This was also true during the 2020-2021 fireworks ban, despite fireworks activity being reduced. Likely to compensate for extra flight costs, most geese moved less and increased their feeding activity in the following days. Our findings indicate negative effects of NY fireworks on wild birds beyond the previously demonstrated immediate response.

fireworks are popular in Japan for 400 years. They are made by a twisted paper simply wrapping 0.1g of black powder at the lower end. Ignited there, the powder melts in a fireball of molten salts, ejecting droplets seen as light streaks. The droplets successively fragment up to eight times leading to ever-smaller size and their branched light streaks traces are similar to pine needles. The phenomenon involves chemical reactions, thermal decomposition of metastable compounds, gas bubble nucleation and bursting, the formation of liquid ligaments, and droplets. We depict the features of this unique direct fragmentation cascade in nature, where thermal diffusion inside each droplet determines its lifetime. Droplet radius getting exponentially smaller until thermal production and heat losses equilibrate. We compute and document experimentally the number of fragmentation steps, and the overall size of the light streaks as well.

Fireworks are used worldwide to celebrate national, religious, cultural festivals and holidays. However the use of fireworks is associated with preventable injuries. We aim to review cases of burns and trauma caused by fireworks presenting to a regional burns and plastic surgery unit in the United Kingdom. We hope our findings will help to guide future firework-related safety practices in the UK. A retrospective review was performed of all patients presenting to our tertiary burns and plastic surgery unit with burns and/or trauma sustained from fireworks over a ten-year period from October 2004 to October 2014. A total of 93 patients were identified. Medical case notes were reviewed, patient demographics, aetiology of injury, management and patient outcomes were recorded. A cohort of 93 patients with burn injuries caused by fireworks were identified from our database. A total of 74% injuries occurred in October and November. Mechanism of injury included contact, flash, flame burns a...

The potential of the atmospheric fine aerosols (PM2.5) to generate reactive oxygen species (ROS) during firework activity in Diwali festival was assessed by the dithiothreitol (DTT) assay at a site in the Indo-Gangetic Plain, India. The 12-h mean PM2.5 was found to be 262.9 ±150.7 µg m-3 during the study period which was 4.4 times exceeded the NAAQS limits. Firework activity was also characterized by increased levels of gaseous pollutants (NOx, SO2, CO and O3), and trace metal concentrations like Ba, Pb, Cu, Fe, Mg, K, Al and Mn. Elevated PM2.5-NOx slope for fireworks including traffic emissions suggested significant contribution of fireworks. The highest value of PM ROS activity, volume-based DTT value was 1.37 nmol min-1 m-3 and mass-based DTT value was 11.77 pmol min-1 μg-1, found in the next morning of Diwali, suggesting stronger PM associated ROS activity due to fireworks. A positive association was found between redox-active metals like Cd, Cr, Cu, Ni, and V and DTT activity t...

Zusammenfassung Hintergrund und Ziel Die kontinuierliche Erfassung von Augenverletzungen durch Pyrotechnik in den Tagen um Silvester über 6 Jahre ermöglicht uns, Verletzungszahlen, Verletzungsmuster und Unfallhergänge im Jahresvergleich zu untersuchen. Zur Entlastung der Krankenhäuser wurden in Deutschland im Rahmen der COVID-19-Pandemie für die Jahreswechsel 2020/21 und 2021/22 ein Verkaufsverbot für Pyrotechnikartikel und Versammlungsbegrenzungen umgesetzt. Wir untersuchen, welchen Einfluss diese Maßnahmen auf die Anzahl von feuerwerksbedingten Augenverletzungen hatten. Außerdem betrachten wir, ob dies zu einer Zunahme schwerer Verletzungen geführt hat und ob ein Zusammenhang mit einer vermehrten Nutzung selbst gebauter oder in Deutschland nicht zugelassener Pyrotechnik bestehen könnte. Methoden Mit unserem Online-Fragenbogen erfassen wir anonymisierte Daten zu Patienten, Unfallhergang und seit 2017/18 auch zur Beschaffung der eingesetzten Pyrotechnikartikel. Ergebnisse Unsere Aus...

On 2016 Feb 19, nine Rosetta instruments serendipitously observed an outburst of gas and dust from the nucleus of comet 67P/Churyumov-Gerasimenko. Among these instruments were cameras and spectrometers ranging from UV over visible to microwave wavelengths, in situ gas, dust and plasma instruments, and one dust collector. At 09:40 a dust cloud developed at the edge of an image in the shadowed region of the nucleus. Over the next two hours the instruments recorded a signature of the outburst that significantly exceeded the background. The enhancement ranged from 50 per cent of the neutral gas density at Rosetta to factors >100 of the brightness of the coma near the nucleus. Dust related phenomena (dust counts or brightness due to illuminated dust) showed the strongest enhancements (factors >10).

This bachelor is applied to the design and development of an application for Android devices, to improve and facilitate the lives of people with intellectual functional diversity, with disorders such as ASD. The application serves as a tool for planning and organizing daily tasks that may arise in the lives of different users. For the planning of the tasks an interface is provided, intuitive and adapted by pictograms, where you can navigate in a simple way and create tasks as the user wishes. In this application you can create tasks that the user has to perform daily or on a specific date, for the construction of the tasks four main parts have been included that contains a task for its correct execution. These sections are the objects that must be carried to perform the task, the different situations that surround us socially and that must be taken into account to perform the task normally, the duration of each task and the steps to follow to complete the task successfully. The final user of the application is the people who suffer from ASD, that is why the focus of the application is made with the idea that teachers or tutors of this type of people can program the tasks, of their students or mentees, in their devices or so that users who have the capabilities to perform the programming of their own tasks can use it. Within the application tasks are organized in two different ways, one according to the date in which it must be done that will be included in the section called Agenda and another according to the category of tasks to which they belong that will be in the Categories section.

People use fireworks to celebrate religious and other holidays in many countries around the world. Fireworks have been banned in a lot of countries but still pose a high potential risk of injuries, especially among male children. Hands and fingers sustain the largest number of injuries followed by legs, then eye injuries. In addition, the lesions from fireworks can be "life-changing" if it occurs on someone's dominant hand, which may never regain its original function if the injury is very severe, or if it produces loss of vision.

Stippling is an artistic technique that has been used profusely in antiquity. One of the main problems is that it requires great skill and patience to achieve excellent results due to the large number of points that must be drawn even for small formats. The use of computers, in general, and GPUs, in particular, with their computing capacity, has allowed to overcome many of these limits. We present a real-time GPU stippling program that combines the advantages of positioning based on Weighted Centroidal Voronoi Diagrams and the realistic aspect of the scanned points.
