Production and purification of rare-earth elements (REE) is among the most demanding separation practices. In general, extracting REE from natural ores requires a large amount of chemicals and energy. Separating the ores contents is also a complex process which needs a tremendous amount of organic solvent mixtures to produce high purity lanthanides. Partial mitigation to this issue lies in urban mining. Recycling old, discarded electronics is an important step in implementing the circular economy concept, making electronics more sustainable. In this work, specific components of old mobile phones were selected for targeted metal recovery. The main focus was on treating permanent magnets containing Nd, Pr and Dy as REE. These magnets were dissolved with nitric acid and the dissolutions were used to measure multicomponent adsorption in different polymeric commercial cationic resins. The adsorption of lanthanides on Amberlite IR-120 and DOWEX 50WX8 resins is found to reach equilibrium within 60 minutes. Across all the metals and lanthanides, Amberlite IR-120 has shown a greater adsorption. Generally, it is observed that more metals are adsorbed at higher pH values. This behavior seems to be consistent for both metals and lanthanides. The experimental data of the three lanthanides (Pr+3 , Nd+3 , and Dy+3) was fitted with diverse models and Sips rendered the best results. Freundlich and Langmuir models also provide satisfactory correlation coefficients

Yes / Background: The use of digital technology in health and social care is developing rapidly. It is promoted in UK policy and research which suggests varied results surrounding its implementation and outcomes. Introduction: This article aimed to test the implementation and outcomes of a short messaging service sent to a dedicated phone. The target cohort were drug treatment clients in two sites in Northern England. Materials and methods: Through staff focus groups and interviews with a small cohort of clients, the implementation and perceptions of the system were examined. Results: Nineteen participants were recruited to site 1 (15 male, 4 female, average age=37.7 years) and 12 participants were recruited to site 2 (9 male, 3 female, average age=40.3 years). One outcome that was of interest was well-being in treatment which, in this study, was described as an overall sense of feeling better rather than just focusing on the rehabilitation aspect of the programme. Other outcomes included: the successful completion of treatment and any relapse or associated reported drug use. Discussion: The system shows some evidence of its ‘social actor’ role; however, its implementation was hindered by staff citing that it called for increased resources. For future implementation the use of client’s own phones may be considered which may help to embed the system more fully in recovery planning and targeting clients at a different treatment stage. Conclusions: Despite some indications of positive results for clients and a perception that the system may have value as an addition to existing clinical interventions, more evaluation is required to determine whether this system can be implemented in a drug treatment setting.

Introdução: A mortalidade materna é aquela resultante de complicações diretas e indiretas da gravidez, parto ou puerpério, e um indicador de saúde da mulher bem como do desempenho dos sistemas de atenção à saúde. O Planejamento Familiar é considerado fundamental na diminuição das taxas de mortalidade materna. A implantação de estratégias efetivas de planejamento familiar no pós-parto (PFPP) poderia contribuir na diminuição das taxas de morbidade e mortalidade materna e infantil, bem como do número de gestações não planejadas e abortos inseguros. O uso de Tecnologias de Informação e Comunicação (TIC) em uma intervenção educativa em saúde de PFPP poderia ser considerado uma ferramenta complementar útil na atenção pós-natal. Objetivo: Determinar se o envio de mensagens de texto via Short Message Service (SMS) sobre PFPP, é um complemento útil para o acompanhamento pós-natal, incentivando o uso de anticoncepcional no pós-parto e o retorno à consulta de puerpério. Métodos: Ensaio clínico aleatorizado controlado por grupo . Realizado entre fevereiro de 2015 e junho de 2016 em Ribeirão Preto. Com 420 mulheres, 326 mulheres do grupo de controle e 94 mulheres do grupo com intervenção, cada grupo estava composto por 10 Unidades Básicas e Distritais de Saúde. Mulheres do grupo com intervenção, com idade igual ou superior a 18 anos e com idade gestacional inferior a 20 semanas, foram convidadas a cadastrar-se no programa, após o aceite de participação, foi enviado o primeiro grupo de mensagens com informações referentes ao parto e gravidez, este envio terminava após o parto. Dentro das primeiras 48 horas pós-parto a mulher era entrevistada na maternidade, sendo coletados dados sociodemográficos, e do histórico sexual e reprodutivo, quatro dias após o parto as mulheres do grupo com intervenção que aceitaram receber as mensagens após o parto, receberam o segundo grupo de mensagens durante oito semanas com informações sobre contracepção no pós-parto. No terceiro mês após o parto foram entrevistadas as 420 no domicílio, o uso de anticoncepcional no pós-parto e assistência à consulta puerperal foram avaliados como desfechos principais. Todas as mulheres assinaram o Termo de Consentimento Livre e Esclarecido. Resultados: A taxa total de uso de anticoncepcional foi de 92% no terceiro mês após o parto, 89% foram anticoncepcionais hormonais. Em relação á consulta puerperal, 76% das mulheres compareceram à consulta. 7 Conclusões: Não houve diferencia estatisticamente significante entre os grupos, talvez o impacto deste tipo de intervenção educativa pode ser diferente em outros contextos e regiões brasileiras onde a informação em saúde é mais defasada e as mulheres têm mais dificuldades no acesso ao serviço de saúde. Este foi o primeiro estudo da literatura que avaliou o impacto de mensagens educativas via SMS sobre uso de contraceptivos após três meses do parto. Além de promover informação através de SMS, numa linguagem de fácil entendimento para as mulheres sobre saúde reprodutiva, a proposta deste estudo possibilitou a participação ativa dessas mulheres, por possuir um sistema de mensagem de texto bidirecional. / Introduction: Maternal mortality is the result of direct and indirect complications of pregnancy, childbirth or puerperium, and an indicator of women\'s health as well as the performance of health care systems. Family Planning is considered to be crucial in reducing maternal mortality rates. The implementation of effective family planning strategies in the postpartum period (FPPP) could contribute to the reduction of rates of maternal and infant morbidity and mortality, as well as the number of unplanned pregnancies and unsafe abortions. The use of Information and Communication Technologies (CIT) in a FPPP health education intervention could be considered a useful complementary tool in postnatal care. Objective: To determine if the sending of text messages via Short Message Service (SMS) on FPPP is a useful complement to postnatal follow-up, encouraging postpartum contraceptive use and the return to puerperal consultation. Methods: Conglomerate-controlled randomized clinical trial. Held between February 2015 and June 2016 in Ribeirão Preto. With 420 women, 326 women from the conglomerate control and 94 women from the conglomerate with intervention, each conglomerate was composed of 10 Basic and District Health Units. Women of the conglomerate with intervention, aged 18 years or above and with gestational age less than 20 weeks, were invited to join the program, after accepting participation, was sent the first group of messages with information regarding delivery and pregnancy, this shipment ended after delivery. Within the first 48 hours postpartum, the woman was interviewed in the maternity ward, and socio-demographic data and sexual and reproductive history were collected. Four days after delivery, women from the conglomerate with intervention who accepted to receive postpartum messages received the second group of messages for eight weeks with information on postpartum contraception. In the third month after delivery, the 420 women were interviewed at home, postpartum contraceptive use and puerperal consultation were evaluated as the main outcomes. All the women signed the Free and Informed Consent Form. Results: The total contraceptive use rate was 92% in the third month after delivery, 89% were hormonal contraceptives. Regarding the puerperal consultation, 76% of the women attended the consultation. Conclusions: There was no statistically significant 9 difference between groups, perhaps the impact of this type of educational intervention may be different in other Brazilian contexts and regions where health information is more lagged and women have more difficulties in accessing the health service. This was the first study in the literature that evaluated the impact of educational messages via SMS on contraceptive use after three months of childbirth. In addition to promoting information through SMS, in a language that women can easily understand about reproductive health, the proposal of this study made possible the active participation of these women, because it has a two-way text message system.

In this dissertation, a series of printed multiband antennas for slim mobile communication devices are presented. The study mainly focuses on how to effectively enhance the impedance bandwidth. With the equivalent LC matching circuit integrated in the antennas, wide impedance bandwidth can be obtained without increasing the size of the antennas. Note that the equivalent matching circuit can be formed by the coupling strip and the shorting strip to generate capacitance and inductance, respectively. In addition, the effects on the user's hand, head and whole body will be analyized. Also, the issue of the hearing aid compatibility will be discussed in this dissertation.

There are large groundplane variations for the folder-type mobile phone in the talk and idle conditions, which makes its embedded antennas not easy to maintain good radiation characteristics in the two states. The radiation efficiencies in the idle condition are often less than 15%. To solve this problem, two novel antennas for the folder-type mobile phone are proposed. The first antenna is the coplanar coupled-fed planar inverted-F antenna. The antenna can cover GSM850/900/DCS/PCS operation in the talk condition, and the radiation efficiencies over the desired operating bands in the idle condition is larger than 32%, which is acceptable for practical applications for the folder-type mobile phone. The second antenna is the ultra-wideband coupled-fed loop antenna. The antenna can cover GSM850/900/DCS/PCS/UMTS penta-band operation in the talk condition. In the idle condition, good performances over the five operating bands can still be obtained, and the radiation efficiencies are better than 53%. The effects of the housing and the user's hand and head on the antenna are also studied. From the obtained results, it is seen that the effects of the housing on the radiation efficiencies are small. However, since the user's hand and head are high-loss materials, large decrease in the radiation efficiencies is usually observed.

In this dissertation, a variety of novel mutiband WWAN loop antennas are presented. By designing proper coupled-fed mechanisms for the proposed loop antennas, the impedance bandwidth of the loop antenna can be greatly enhanced to achieve two wide operating bandwidths at antenna¡¦s lower and upper bands to easily cover GSM850/900/1800/1900/UMTS operation. With two wider operating bandwidths obtained, the tolerance of frequency detuning and the capability of bandwidth tuning of the loop antennas can be improved for practical applications. In addition, in order to find methods to meet the SAR and HAC criterions, the proposed small-size chip loop antenna studied in this dissertation which is suitable for both bar-type and folder-type mobile phone applications are simulated and analyzed for SAR and HAC issues.

Abstract Background: In Sweden self-harm behaviors among young people have been a difficult area to handle in psychiatric care. From the government's efforts have been made to synchronize the knowledge and experience from the local level aiming to prevent, reduce and faster identify self-harm among young people. M-Health refers to technology such as smartphones, notebooks and mobile phones provide.  These mobile devices have come to revolutionize aspects of health care perhaps mostly among young people, live their digital lives by these electronic media. Aim: To illuminate the use of m-Health in the treatment of mental illness and to present a draft of a mobile application that helps professionals in work with young people active in a mild to moderate self-injury. Method: A literature review based on an analysis of twelve scientific articles with qualitative and quantitative approach. We searched in November 2013-January 2014 Ebsco and PubMed databases.  Results: The literature review is presented as gains and losses in use of m-Health in the treatment of mental illness. The focus has been on what is possible to achieve with a mobile application in this area of concern. It appeared that young people show positive attitudes to using an application in monitoring of psychiatric symptoms and gained more control mental health. The professionals sees advantage in terms of more truthful symptom monitoring in real time in comparison with retrospective self-monitoring, expedited handling processes and better treatment outcomes. Conclusion: We interpret the results of the studies about m-Health as an opportunity for nurses to meet young people, active in a mild to moderate self-harm. An m- Health intervention based on an application for young people could make it easier for nurses to improve their communication and treatment outcomes. Care initiatives and relevant actions can then be tailored to young people's cultural values, beliefs and lifestyle.

Experts estimate that by 2013, every adult in the world will own a mobile phone. Mobile technologies are one of the fastest growing and most widely adopted technologies in history. This study seeks to understand the impacts of an increasingly mobile culture in the United States, focusing on how being “always on” impacts individuals' relationships with work. Being always on refers to an individual’s propensity to remain continuously connected to the world through a web-enabled, mobile technology device, such as an iPhone or BlackBerry. Influenced by Clark's (2000) work-family border theory, I conducted 49 in-depth interviews, in order to develop a communicative model of being always on. The model is characterized by using new mobile technologies, needing to be connected, blurring boundaries between work and non-work spheres, identifying with work, working long hours, and having work-life balance. Being always on is linked to a strong work identity and desire for control over one's time. However, being constantly connected with a smartphone also means being more connected to work; it has become easier to work longer hours, have work leak into personal time, and slowly but ultimately lose control over the boundaries between work and non-work domains. Ironically, individuals who are always on in order to gain more control over their time may actually end up giving up more control than they gain. However, always-on individuals actually feel like they have an appropriate work-life balance, which complicates traditional understandings of the meaning of “balance.” Instead, these findings suggest always-on individuals actually “atomize,” a term that refers to the breaking down of communicative tasks into small pieces to can be completed anywhere, at any time, enabling flexibility and control. / text
