Abstract
Background
Circadian clock alterations were poorly reported in trauma patients, although they have a critical role in human physiology. Core body temperature is a clinical variable regulated by the circadian clock. Our objective was to identify the circadian temperature disruption in trauma patients and to determine whether these disruptions were associated with the 28-day mortality rate.

Methods
A retrospective and observational single-center cohort study was conducted. All adult severe trauma patients admitted to the intensive care unit of Aix Marseille University, North Hospital, from November 2013 to February 2018, were evaluated. The variations of core body temperature for each patient were analyzed between days 2 and 3 after intensive care unit admission. Core body temperature variations were defined by three parameters: mesor, amplitude, and period. A logistic regression model was used to determine the variables influencing these three parameters. A survival analysis was performed assessing the association between core body temperature rhythm disruption and 28-day mortality rate. A post hoc subgroup analysis focused on the patients with head trauma.

Results
Among the 1584 screened patients, 248 were included in this study. The period differed from 24 h in 177 (71%) patients. The mesor value (°C) was associated with body mass index and ketamine use. Amplitude (°C) was associated with ketamine use only. The 28-day mortality rate was 18%. For all trauma patients, age, body mass index, intracranial hypertension, and amplitude were independent risk factors. The patients with a mesor value < 36.9 °C (p < 0.001) and an amplitude > 0.6 °C (p < 0.001) had a higher 28-day mortality rate. Among the patients with head trauma, mesor and amplitude were identified as independent risk factors (HR = 0.40, 95% CI [0.23–0.70], p = 0.001 and HR = 4.73, 95% CI [1.38–16.22], p = 0.01).

Conclusions
Our results highlight an association between core body temperature circadian alteration and 28-day mortality rate. This association was more pronounced in the head trauma patients than in the non-head trauma patients. Further studies are needed to show a causal link and consider possible interventions.

Background: Japanese encephalitis (JE) is a mosquito-borne disease with high case fatality and no specific treatment. Little is known about the community’s (especially parents/guardians of children) awareness regarding JE and its vaccine in Yangon region, which bears the highest JE burden in Myanmar. Methods: We conducted a community-based cross-sectional study in Yangon region (2019) to explore the knowledge and perception of parents/guardians of 1-15 year-old children about JE disease, its vaccination and to describe JE vaccine coverage among 1-15 year-old children. We followed multi-stage random sampling (three stages) to select the 600 households with 1-15 year-old children from 30 clusters in nine townships. Analyses were weighted (inverse probability sampling) for the multi-stage sampling design. Results: Of 600 parents/guardians, 38% exhibited good knowledge of JE, 55% perceived JE as serious in children younger than 15 years and 59% perceived the vaccine to be effective. Among all the children in the 600 households, the vaccination coverage was 97% (831/855). Conclusion: In order to reduce JE incidence in the community, focus on an intensified education program is necessary to sustain the high vaccine coverage in the community.
The Missing New Funds
Authors: Zhu Qifei 
Published: January 2020

Many papers in the mutual fund literature rely on a sample that matches the Center for Research in Security Prices (CRSP) mutual fund database with the fund holdings data from Thomson Reuters (TR) s12 database. I document that about 58% of newly founded U.S. equity mutual fund share classes in the CRSP mutual fund database from 2008 to 2015 cannot be matched to the TR database. Funds that are missing from the TR database tend to be smaller, have higher turnover ratios, receive higher fund flows, and have higher four-factor alphas. These differences are robust within same cohorts of funds. Index funds and exchange-traded funds are more likely to be omitted than actively managed funds.

Published: January 2020

O artigo objetiva analisar as principais ações da política educacional para o Ensino Médio no contexto da Lei nº 13.415, sob a influência do neoliberalismo. Para se problematizar o objeto de estudo e abordar às questões de investigação, trabalhou-se com teóricos como Cunha (2005); Kuenzer (1997); Freitas (2018), Motta; Frigotto (2017). Sob esse prisma, os documentos oficiais conexos a essas políticas foram mapeados e analisados problematizando os interesses políticos e econômicos em voga; as disputas ideológicas contemporâneas, conferindo atenção à flexibilização curricular e à concepção de competências no âmbito do ensino. Os resultados permitiram identificar contradições nos discursos oficiais e na implantação e concretização das políticas de Ensino Médio, desvelando um distanciamento entre o pretendido e o realizado. Ademais, identificou-se que a proposta de criação dos IFs configura-se como possibilidade de superação do modelo formativo economicista , na medida em que desenvolve um processo formativo de unidade entre o trabalho, a ciência e a cultura.

The reported high-performance sky-blue DFB laser is promising in enabling unexplored dense wavelength-division multiplexing schemes in VLC, narrow-line filtered systems, and other applications where single-frequency lasers are essential such as atomic clocks, high-resolution sensors, and spectroscopy. Single-frequency emitters at the sky-blue wavelength range will further benefit applications in the low-path-loss window of underwater media as well as those operating at the H-beta Fraunhofer line at

Published: January 2020

Abstract
Museums use gelatin capsules to store small objects and specimens, despite limited documentation of their long-term viability. The Royal Alberta Museum (RAM of Canada) uses gelatin capsules to store seeds, bones, and plant material because of their ease of use, transparency, soft-bodied walls, size availability, and low cost. Recently, RAM staff reported damaged capsules from the palaeontology collections. We evaluated 499 capsules used to store specimens accessioned in 1986 and 1988 and investigated capsule properties using Fourier transform infrared spectroscopy and Oddy testing. Only 4.21% of inspected capsules were dented, cracked, and/or fractured. Based on interviews and testing, we determined that damage to capsules likely resulted during handling (i.e., applied force when opening). We conclude that gelatin capsules offer a good, inexpensive method for long-term storage of small, dried specimens in environmentally controlled conditions. Alternatives to gelatin capsules exist, although their pros and cons require evaluation before use. All storage methods require continuous monitoring for signs of container or specimen deterioration.

The implementation of the expertise went well in accordance with the existing duties, from the planning to the evaluation process. However, the work ethic of the teaching staff has not been running optimally due to two factors, i.e., (1) internal factor which relates to cultural diversity and various; educational-economy-social background; and (2)External factor which relates to wages, work climate, inculcation of attitudes, and time owned by the educational staff.
Nonisothermal Cold Crystallization Kinetics of Poly(lactic acid)/Bacterial Poly(hydroxyoctanoate) (PHO)/Talc
Authors: Alhaddad Omaima , El-Taweel Safaa H. , Elbahloul Yasser 
Published: January 2020

AbstractThe effects of bacterial poly(hydroxyoctanoate) (PHO) and talc on the nonisothermal cold crystallization behaviours of poly(lactic acid) (PLA) were analysed with differential scanning calorimetry (DSC), and the thermal stability of the samples was observed with thermal gravimetric analysis (TGA). The modified Avrami’s model was used to describe the nonisothermal cold crystallization kinetics of neat PLA and its blends. The activation energies E for nonisothermal cold crystallization were calculated by the isoconversional method of Kissinger-Akahira-Sunose (KAS). The DSC results showed that the PLA/PHO blends were immiscible in the whole studied range, and as the PHO and talc content increased, the crystallization rate of PLA accelerated, and the crystallinity of PLA in the PLA samples increased. The values of the Avrami exponent indicated that the nonisothermal cold crystallization of the neat PLA and its blends exhibited heterogeneous, three-dimensional spherulitic growth. The E values were strongly dependent on PHO and talc. The TGA results showed that the presence of PHO and talc slightly influenced the thermal stability of PLA.

Abstract
In this study, the electromagnetic interference (EMI) shielding effectiveness (SE) of polymer composites based on natural graphite in flakes (NGF) and silicone rubber was investigated with the aim to contribute to the development of the technology of electromagnetic shielding materials. This topic has attracted great attention to the aeronautical and aerospace applications, due to the serious problems that EMI can cause to the functioning of electronic devices. According to this, the present work has produced samples of composite materials with variations on the sizes of the filler particles and composition of the samples. The electromagnetic characterization of the samples is given by the Vector Network Analyzer (VNA) in the X-band frequency range (8.2 – 12.4 GHz). The results indicate that the variation of particle sizes is determinant to the SE performance along with the X-band frequency range. Furthermore, the expansion of the range of granulometry allows controlling the curves of the peaks along the X-band.

The European project entitled "Integrating adults and the elderly towards a Europe of knowledge", coordinated by the University of Almería, within the actions of "Grundtvig learning partnerships for adult education", has carried out the assessment of an educational program for people over 55 years in five countries. The aim of the learning partnership was “to encourage the development of innovative practices in education of older people and their transfer between countries”.
Methods: Some of the following teaching tools and methods were used to promote intercultural communication skills: simulation activities, followed by reflective discussion and/or written analysis; guided group activities; local visits to contact people from other countries; ethnographic projects.
Results: The courses provide knowledge and understanding about culture, institutions and different ways of life in diverse communities, and encourage reflection about their own cultural behaviour, practices and attitudes, as well as those of others. Old people enhance communication in their community, by means of meetings in which they talk about their common concerns. This can help the elderly to overcome problems and reduce feelings of loneliness. The courses also help old people acquire new knowledge and skills in a rapidly changing world.
Conclusions: Participants’ motivation increased as the sessions were developed, since the contents of the classes agreed with their own interests, with a constant widening of knowledge. Everybody had an active role in the discussions. This training has shown some aspects about ageing, such as the removal of the image of the idle retired person; at the same time it promotes active retirement, intergenerational relationships and independence, and improves social and personal skills

The process of population ageing is observed not only in Poland but also in other European countries. Physiological processes of ageing reduces the functional capacity. In particular, associated diseases, progressive weakness and failure of the motor system increases the risk of collapse in seniors. Dangerous consequences of falls, inter alia, injuries, can often cause death, what justifies its classification as a so-called geriatric giant. Health and psychosocial consequences of falls should be noted. Therefore, there is a great need for induction of preventive measures. Many results of studies constantly show, that an effective intervention in preventing falls in seniors should include, first and foremost, multidirectional rehabilitation, which aims to improve balance and increase postural strength muscle. In addition, prevention should include: patient education, pharmacotherapy prescribed by a medical specialist, eyesight improvement, elimination of potential risks surrounding the patient. The introduction of multi-directional prevention of falls can reduce the risk of their occurrence up to 50%
