We experimentally study the generation and amplification of stable picosecond-short optical pulses by a master oscillator power-amplifier configuration consisting of a monolithic quantum-dot-based gain-guided tapered laser and amplifier emitting at 1.26 μm without pulse compression, external cavity, gain-or Q-switched operation. We report a peak power of 42 W and a figure-of-merit for second-order nonlinear imaging of 38.5 W2 at a repetition rate of 16 GHz and an associated pulse width of 1.37 ps.

Globally, approximately 208 million people aged 15 and older used illicit drugs at least once in the last 12 months; 2 billion consumed alcohol and tobacco consumption affected 25% (World Drug Report, 2008). In the United States, 20.1 million (8.0%) people aged 12 and older were illicit drug users, 129 million (51.6%) abused alcohol and 70.9 million (28.4%) used tobacco (SAMHSA/OAS, 2008).Usually considered a problem specific to men (Lynch, 2002), 5.2% of pregnant women aged 15 to 44 are also illicit drug and substance abusers (SAMHSA/OAS, 2007). During pregnancy, illicit drugs and substance abuse (ID/SA) can significantly affect a woman and her infant contributing to developmental and communication delays for the infant and influencing parenting abilities (Budden, 1996; March of Dimes, 2006b; Rossetti, 2000). Feelings of guilt and shame and stressful experiences influence approaches to parenting (Ashley, Marsden, & Brady, 2003; Brazelton, & Greenspan, 2000; Ehrmin, 2000; Johnson, & Rosen, 1990; Kelley, 1998; Rossetti, 2000; Velez et al., 2004; Zickler, 1999). Parenthood is an expanded role that can be a trying time for those lacking a sense of self-efficacy and creates a high vulnerability to stress (Bandura, 1994). Residential treatment programs for ID/SA mothers and their children provide an excellent opportunity for effective interventions (Finkelstein, 1994; Social Care Institute for Excellence, 2005). This experimental study evaluated whether teaching American Sign Language (ASL) to mothers living with their infants/children at an ID/SA residential treatment program increased the mothers’ self-efficacy and decreased their anxiety. Quantitative data were collected using the General Self-Efficacy Scale and the State-Trait Anxiety Inventory showing there was both a significant increase in self efficacy and decrease in anxiety for the mothers. This research adds to the knowledge base concerning ID/SA mothers’ caring for their infants/children. By providing a simple low cost program, easily incorporated into existing rehabilitation curricula, the study helps educators and healthcare providers better understand the needs of the ID/SA mothers. This study supports Bandura’s theory that parents who are secure in their efficacy can navigate through the various phases of their child’s development and are less vulnerable to stress (Bandura, 1994).

Science has remained in hegemonic position among the various forms of knowledge that enable us perceive our surroundings. After a growing movement of introversion of the scientific field, which enabled the empowerment of the academy, it is growing today the discussion about the need to spread knowledge of this area to society. Our study aims to observe the discourse of institutional science communication, taking into account the historical conditions that made possible the emergence of science as legitimate observation of nature and of man and also the credibility granted to the media. Therefore, we have as our study object the editorials of the Darcy magazine, for scientific and cultural journalism of the University of Brasilia. We focused on observing the discourse of knowledge sharing by the media, using the concepts of field, from Bourdieu’s work, and Agamben’s "profanation" together with notions from the organizational communication area. Also, the concepts of dispositive, discourse and knowledge-power used are based on the studies from the French school which associate them to the need of thinking power as a relation between what is and what is not said, having Michel Foucault as an important exponent of this area. The research, which uses as a method the Discourse Analysis, shows us a process of mutual validation of the scientific and journalistic discourses, which contribute to the strengthening of the institution itself as well as the scientific field, in texts which have as a backdrop the institutional image and reputation.

L'RCMT (Regional Centroid Moment Tensor), realizzato e gestito dai ricercatori dell'INGV (Istituto Nazionale di Geofisica e Vulcanologia), è dal 1997 il catalogo di riferimento per gli eventi sismici avvenuti nell'area Europea-Mediterranea, ossia nella regione avente longitudine compresa tra 10° W e 40° E e latitudine compresa tra 25° N e 60° N. Tale regione è caratterizzata da un'attività tettonica complessa, legata non soltanto alla convergenza delle placche Euroasiatica ed Africana, ma anche al movimento di altre placche minori (ad esempio, la placca Arabica), che tutte insieme danno origine ad una vasta gamma di regimi tettonici. Col termine RCMT si indica un particolare tipo di tensore momento sismico, la cui determinazione avviene su scala regionale, per eventi sismici aventi M_w >= 4.5 (M_w >= 4.0 per gli eventi che avvengono nella penisola italica). Il tensore momento sismico è uno strumento fondamentale per caratterizzare natura ed entità di un terremoto. Da esso, infatti, oltre alla magnitudo momento M_w, si ricava anche il meccanismo focale. Comunemente rappresentato sotto forma di beach ball, consente di individuare il tipo di movimento (distensivo, compressivo o trascorrente, o anche una combinazione del primo o del secondo con il terzo) avvenuto sulla faglia che ha provocato il terremoto. I tensori momento sismico permettono, quindi, di identificare le faglie che si attivano durante una sequenza sismica, di comprendere la loro cinematica e di ipotizzare la successiva evoluzione a breve termine. Scopo di questa relazione di laurea è stato derivare le relazioni che intercorrono fra le M_w dell'RCMT e le M_w del CMT (Centroid Moment Tensor della Columbia University), del GFZ (Deutsches GeoForschungsZentrum di Postdam) e del TDMT (Time Domain Moment Tensor). Le relazioni sono state ottenute applicando il metodo dei minimi quadrati agli eventi comuni, che sono stati selezionati utilizzando alcuni semplici programmi scritti in Fortran.

Extra Ovarian Primary Peritoneal Carcinoma (EOPPC) is a rare type of adenocarcinoma of the pelvic and abdominal peritoneum. The objective examination and the histological aspect of the neoplasia virtually overlaps with that of ovarian carcinoma. The reported case is that of a 72 year-old patient who had undergone a total hysterectomy with bilateral annessiectomy surgery 20 years earlier subsequently to a diagnosis for uterine leiomyomatosis. The patient came to our attention presenting recurring abdominal pain, constipation, weight loss, severe asthenia and fever. Her blood test results showed hypochromic microcytic anemia and a remarkable increase CA125 marker levels. Instrumental diagnostics with Ultrasound (US) and CT scans indicated the presence of a single peritoneal mass (10-12 cm diameter) close to the great epiploon. The patient was operated through a midline abdominal incision and the mass was removed with the great omentum. No primary tumor was found anywhere else in the abdomen and in the pelvis. The operation lasted approximately 50 minutes. The post-operative course was normal and the patient was discharged four days later. The histological exam of the neoplasia, supported by immunohistochemical analysis, showed a significant positivity for CA 125, vimentin and cytocheratin, presence of psammoma bodies, and cytoarchitectural pattern resembling that of a serous ovarian carcinoma even in absence of primitiveness, leading to a final diagnosis of EOPPC. The patient later underwent six cycles of chemotherapy with paclitaxel (135 mg/m2/24 hr) in association with cisplatin (75mg/m2). At the fourth year follow-up no sign of relapse was observed. .

The influence of different infectious agents and their association with human papillomavirus (HPV) in cervical carcinogenesis have not been completely elucidated. This study describes the association between cytological changes in cervical epithelium and the detection of the most relevant aetiological agents of sexually transmitted diseases. Samples collected from 169 patients were evaluated by conventional cytology followed by molecular analysis to detect HPV DNA, Chlamydia trachomatis , herpes simplex virus 1 and 2, Neisseria gonorrhoeae , Mycoplasma genitalium , Trichomonas vaginalis, and Treponema pallidum , besides genotyping for most common high-risk HPV. An association between cytological lesions and different behavioural habits such as smoking and sedentariness was observed. Intraepithelial lesions were also associated with HPV and C. trachomatis detection. An association was also found between both simple and multiple genotype infection and cytological changes. The investigation of HPV and C. trachomatis proved its importance and may be considered in the future for including in screening programs, since these factors are linked to the early diagnosis of patients with precursor lesions of cervical cancer.

Introducción: En la monitorización de salud de la población, a medida que se controla la mortalidad prematura, van ganando terreno los indicadores de "Calidad de Vida" en detrimento de los "Cantidad de Salud". Los instrumentos de medida de Calidad de Vida Relacionados con la Salud (CVRS), pueden ayudar a valorar la aptitud de los trabajadores epilépticos. Objetivo: Observar si la empleabilidad influye en la CVRS de los pacientes epilépticos, y como están afectados los dominios de sensación energía/fatiga y funciones cognitivas, con el cuestionario QOLIE-31. Metodología: Búsqueda bibliográfica utilizando las bases de datos PubMed, Scielo, IBECS, Cochrane Plus, Google Académico y LILACS. El nivel de evidencia se estableció de acuerdo a los criterios de SIGN. Resultados: Se seleccionaron 10 artículos, de 244 artículos recuperados. De ellos, seis son estudios transversales y solo uno obtiene asociación estadísticamente significativa, p<0,001, en el análisis de regresión multivariante, entre trabajo y total QOLIE-31. De los otros cuatro, de validación, tres obtienen asociación estadísticamente significativa con p<0.001, p<0.0001 y p=0,0002, pero solo en el análisis univariante. Variables explicativas con mayor valor predictivo en los dominios de sensación de energía/fatiga y función cognitiva fueron: la frecuencia de las crisis y los síntomas depresivos. Conclusión: No se puede concluir que los epilépticos que trabajan tienen una mejor CVRS que los que no trabajan. Existen sesgos importantes de selección e información, además de diferencias culturales y sociales. Medidas de CVRS podrían ayudar, a la hora de valorar la aptitud de los enfermos epilépticos en el trabajo.

A hipertensão arterial sistêmica (HAS) é uma doença que representa um dos maiores problemas em saúde pública no Brasil e no mundo, gerando elevado custo médico-social. Observamos na unidade Etapa A uma prevalência de 6% de individuos com HAS. O projeto de intervenção tem o objetivo de melhorar a qualidade de vida dos pacientes hipertensos da rede pública de Valparaiso de Goiás – GO. O projeto teve início em abril de 2015 quando fizemos o levantamento dos pacientes hipertensos da área de nossa abrangência, convidamos 30 pessoas a participar do projeto, onde todas atendiam os critérios de inclusão no projeto, todos assinaram o termo de participação que esclarecia os deveres e os objetivos e assim teve início o nosso projeto. Foram realizadas reuniões quinzenais, na unidade de saúde, onde foram discutidos temas relacionados aos fatores de risco da doença. O projeto de intervenção que foi aplicado na nossa unidade, foi desenvolvido em conjunto com toda a equipe de saúde da unidade e contribuiu significamente para o aprendizado e aprofundamento do conhecimento sobre o tema hipertensão arterial, os objetivos foram atendidos quase que na totalidade.
