The Silicon on the Catalysis: Hydrodesulfurization of Petroleum Fractions

The use of silicon in hydrodesulfurization (HDS) catalysts has had an impact on some of the fundamental parameters for the performance of the HDS catalyst, such as dispersion of the active phase, the extent of sulfidation, or the level of promotion. Mesoporous silicates such as MCM-41, SBA-15, the modified surface of γ-alumina with silica, or mixed Al2O3-SiO2 support have showed to affect the metal-support interaction, favoring the so-called type II Co(Ni)–Mo(W)–S structures. The aim of this chapter is to elaborate an analysis on the recent advances in the synthesis design of silicon catalyst support for the hydrodesulfurization of petroleum fractions

Bolsa Multi Uso

Muchas personas no han respetado la distancia social durante la pandemia por Covid-19, lo que ha generado que muchas personas tengan la necesidad de salir a abastecerse de alimentos y productos de primera necesidad, minimizando la frecuencia de salidas, evitando el contacto cercano con otras personas para evitar enfermarse. Por ello, se creó la “Bolso Multi Uso” con sensor de proximidad, la cual avisa mediante un sensor y luz si la distancia social de 1.5m no es respetada. Así, se minimiza el riesgo de contagio y se protege la salud del cliente y su familia. Se dirige un segmento resegmentado, al cual se le ofrece un producto mejorado, que a diferencia de otras maletas o bolsos de mercado, cuenta con un sensor que avisa al cliente de la cercanía de otras personas, recordándole cumplir el protocolo de distancia social. El equipo de trabajo está conformado por profesionales de diversas especialidades como administración de empresas, banca y finanzas y negocios internacionales con amplia experiencia en marketing, ventas y gestión de recursos humanos. Se esperan tener ingreso de hasta S/ 744,369 soles en el quinto año. Asimismo, se obtendría un VANE de S/ 148,099 soles , una TIRE de 52.50% superior al WACC de 14.32%, representando una atractiva alternativa de inversión. Para poder efectuar dicho proyecto se requiere financiar el 40% de la inversión total calculada en de S/ 58,084 soles. Es decir, se requieren S/ 23,233 soles a cambio del 40% de las acciones de la empresa.Many people have not respected social distance during the Covid-19 pandemic, which has generated that many people have the need to go out to stock up on food and basic necessities, minimizing the frequency of outings, avoiding close contact with others people to avoid getting sick. For this reason, the "Multi Use Bag" with proximity sensor was created, which warns by means of a sensor and light if the social distance of 1.5m is not respected. Thus, the risk of contagion is minimized and the health of the client and his family is protected. A resegmented segment is addressed, to which an improved product is offered, which unlike other suitcases or bags on the market, has a sensor that alerts the customer of the proximity of other people, reminding them to comply with the social distance protocol. The work team is made up of professionals from various specialties such as business administration, banking and finance and international business with extensive experience in marketing, sales and human resource management. They are expected to have an income of up to S / 744,369 soles in the fifth year. Likewise, a NPV of S / 148,099 soles would be obtained, an EIRR of 52.50% higher than the WACC of 14.32%, representing an attractive investment alternative. In order to carry out this project, it is necessary to finance 40% of the total investment calculated at S / 58,084 soles. That is, S / 23,233 soles are required in exchange for 40% of the company's shares.Trabajo de investigació

COVID Isolation Eating Scale (CIES): Analysis of the impact of confinement in eating disorders and obesity-A collaborative international study

Confinement during the COVID-19 pandemic is expected to have a serious and complex impact on the mental health of patients with an eating disorder (ED) and of patients with obesity. The present manuscript has the following aims: (1) to analyse the psychometric properties of the COVID Isolation Eating Scale (CIES), (2) to explore changes that occurred due to confinement in eating symptomatology; and (3) to explore the general acceptation of the use of telemedicine during confinement. The sample comprised 121 participants (87 ED patients and 34 patients with obesity) recruited from six different centres. Confirmatory Factor Analyses (CFA) tested the rational-theoretical structure of the CIES. Adequate goodness-of-fit was obtained for the confirmatory factor analysis, and Cronbach alpha values ranged from good to excellent. Regarding the effects of confinement, positive and negative impacts of the confinement depends of the eating disorder subtype. Patients with anorexia nervosa (AN) and with obesity endorsed a positive response to treatment during confinement, no significant changes were found in bulimia nervosa (BN) patients, whereas Other Specified Feeding or Eating Disorder (OSFED) patients endorsed an increase in eating symptomatology and in psychopathology. Furthermore, AN patients expressed the greatest dissatisfaction and accommodation difficulty with remote therapy when compared with the previously provided face-to-face therapy. The present study provides empirical evidence on the psychometric robustness of the CIES tool and shows that a negative confinement impact was associated with ED subtype, whereas OSFED patients showed the highest impairment in eating symptomatology and in psychopathology.This manuscript and research was supported by grants from the Ministeriode Economía y Competitividad (PSI2015-68701-R), Instituto de Salud Carlos III (ISCIII) (FIS PI14/00290/ INT19/00046nd PI17/01167) and co-funded by FEDER funds/European Regional Development Fund (ERDF), a way to build Europe.

Gambling Phenotypes in Older Adults.

International audienceParticipation in gambling is rising in older adults. Indeed, in the coming years, engagement in gambling as a social activity is expected to increase more sharply in the elderly than in any other age group. Due to their exposure to powerful age-specific risk factors such as isolation, inactivity and failing health, older people are highly vulnerable to gambling-related problems. This study aimed to explore the existence of empirical clusters related to gambling habits in a sample of elderly participants from the general population. The sample included n = 361 participants, age range 50-90 years (mean 73.8, SD 8.4). Empirical clusters were identified through a two-step clustering analysis based on a broad set of indicators, including sociodemographic features, psychopathological state, substance use, life events, gambling preferences and scores on screening measures of gambling severity. The prevalence of GD in the study was 1.4%. Two clusters were identified: (a) cluster 1 (labeled as "low risk of gambling problems", n = 265, 73.4%), which included the higher proportion of non-gamblers or individuals who engage only in non-strategic gambling, women, widowed, and lower levels of education (no individual into this group met criteria for GD); and (b) cluster 2 (labeled as "higher risk of gambling problems", n = 96, 26.6%), which included the higher proportion of men, who reported both non-strategic and strategic gambling preferences (all participants diagnosed of GD were grouped into this cluster), older age, longer history of gambling, higher gambling severity, higher use of substances and worse psychopathological state. The elderly constitute a heterogeneous group with regard to gambling phenotypes. The results of this study may prove particularly useful for developing reliable screening tools able to identify older patients at a high risk of gambling problems, and for designing effective prevention and intervention programs
