Phase transformations and mechanical properties of the nitinol alloy with shape memory

We study the Ni55.8Ti44.2 alloy in the form of rods 8 mm and wires 1.5 mm in diameter. By the method of differential scanning calorimetry, we find the temperatures of phase transformations different for the rods and the wires. The stresses corresponding to the onset and termination of phase transformations at room temperature are determined. We also analyze the influence of the diameters of specimens on thetemperatures of phase transformations, deformation of behavior of the alloy, and its mechanical charac-teristics

Faktor-faktor Yang Berhubungan Dengan Keteraturan Pemeriksaan Antenatal Care (Anc) Ibu Hamil Trimester III Di Puskesmas Ranotana Weru Kota Manado

: The high prevalence of maternal and infant mortality is still a problem that cannot be solved. An effort to reduce MMR and IMR is to perform antenatal examination regularly. Antenatal care is one of an intervention to prevent maternal mortality by early detecting of high risk pregnancy. The purpose of this study was to determine the factors associated with the regularity of antenatal care of pregnant women in the third trimester Ranotana Weru Manado City Health Center. Design research is a descriptive study with cross sectional approach. It was done at Ranotana Weru Manado on 8th – 24 nd November 2016. Sampling technique, that is by accidental sampling and sample number as many as 44 people. The research instrument used questionnaire, and maternal health card book. Data were analyzed with Chi Square test in 95% of confidence rate (α<0,05). The results of the research obtained variables related to the regularity of antenatal care is education (p = 0.041), and parity (p = 0.040). While that is not related to the regularity of antenatal care age (p = 0.105), the support of her husband (p = 0.087), earnings (p = 0.157). Conclusion This research is no relationship of education and parity with regularity antenatal care at the health center Weru Ranotana Manado

Association between physical activity and the prevalence of metabolic syndrome: from the Korean National Health and Nutrition Examination Survey, 1999–2012

The purpose of this study was to determine favorable physical activities, by intensity, type, and frequency that would serve to minimize the prevalence of metabolic syndrome. A total of 24,178 individuals participated in the Korean National Health and Nutrition Examination Survey that investigated the risk factors for metabolic syndrome and physical activity including the physical activity type (vigorous and moderate activity, walking, strength, and flexibility) and the frequency (numbers of days per weeks where physical activity lasted at least 10 min per session). Complex-samples analysis, descriptive statistics, Pearson’s Chi-square test, and multivariate logistic regression analyses were conducted to analyze the data. The results confirmed that physical activity had a favorable effect on reducing the occurrence of metabolic syndrome. The lowest prevalence of metabolic syndrome was observed when vigorous physical activity was conducted six times per week (OR 0.65, 95% CI 0.45–0.94). The associated beneficial effects included improvements in the risk factors of metabolic syndrome, depending on the specific physical activity type and frequency. Patients diagnosed, as having metabolic syndrome should be aware of the associated underling risk factors in order to determine a targeted physical activity intervention.

Higgs boson as a gluon trigger: the study of QCD in high pile-up environments

In the forthcoming high-luminosity phase of the LHC many of the most interesting measurements for precision QCD studies are hampered by large pile-up conditions, especially at not very high transverse momenta. However, with the recently discovered Higgs boson, which couples in the heavy top limit directly to gluons, we have access to a novel production process to probe QCD by a colour-singlet current. In this study we compare observables in Higgs boson and Drell-Yan production and investigate whether measuring ratios or subtractions can yield results that are stable in high pile-up environments, and yet sensitive to (small-$p_{\text{T}}$) QCD physics in gluon fusion processes. We present results of Monte Carlo event generator calculations for a few specific examples.Comment: 7 pages, 10 figures, DIS2014 conference proceeding

HMIS Assessment in Mtwara Region and Proposal for Strengthening the MTUHA System

The assessment of the current status of the Health Information System (MTUHA) is a requirement of the Three Regions Health Study in Tanzania. However, because numerous similar assessments and reports have been compiled, this report focuses its attention on the development of a comprehensive plan for strengthening the MTUHA information system. The evaluation component was thus scaled back to provide a quick assessment of the status of the information system in one of the regions (Mtwara). The report briefly describes the methodology (Section 2) utilised in the preparation of the report, and then assesses the key components of an efficient information system (Section 3). Five main areas are assessed, namely the data flow policy, essential data set, human resources for information systems, and access to hardware and software, and then describes the information processing cycle and the steps involved in this cycle. The Recommendations Section (Section 4), while mirroring the structure of the previous section, introduces two new aspects – that of creating a culture of information use, and some detail on the requirements to develop an integrated, long term approach to the development of information systems. This we believe is the main contribution that this report makes to the Tanzanian health sector, The main findings and recommendations are highlighted for the five areas of the assessment. In each section, the findings are briefly described, followed by the\ud recommendations, and comments on the implementation steps\u

Desafios e oportunidades em ética clínica com a implementação do Ato de Fim-da-Vida na Córeia

This paper examines the possible impacts of the Act on Decisions on Life-Sustaining Treatment for Patients in Hospice and Palliative Care or at the End of Life in Korea (Korea’s end-of-life act), legislated in 2016, on the development of hospital ethics committees and clinical ethics consultation services in South Korea. Clinical ethics in Korea has not made much progress in comparison to other subdisciplines of biomedical ethics. While the enactment of this law may give rise to beneficial clinical ethics services, it is possible that customary practices and traditional authorities in Korean society will come into conflict with the norms of clinical ethics. This paper examines how the three main agents of Korean society—family, government, and medical professionals—may clash with end-of-life stage norms in clinical ethics, thus posing obstacles to the development of hospital committees and consultation services. A brief outline of what lies ahead for the progress of clinical ethics practice is explored.Este documento examina los posibles impactos de la Ley de decisiones sobre el tratamiento de soporte vital para pacientes en hospicios y cuidados paliativos, o al final de la vida en Corea (Ley de Corea del Final de la Vida), legislada en 2016, sobre el desarrollo de comités de ética hospitalaria y servicios de consulta de ética clínica en Corea del Sur. La ética clínica en Corea no ha avanzado mucho en comparación con otras subdisciplinas de la ética biomédica. Si bien la promulgación de esta ley puede dar lugar a servicios de ética clínica beneficiosos, es posible que las prácticas tradicionales y las autoridades tradicionales en la sociedad coreana entren en conflicto con las normas de ética clínica. Este documento examina cómo los tres agentes principales de la sociedad coreana —familia, gobierno y profesionales médicos— pueden chocar con las normas de ética clínica al final de la vida, lo que plantea obstáculos para el desarrollo de comités hospitalarios y servicios de consulta. Se explora un breve resumen de lo que queda por delante para el progreso de la práctica de la ética clínica.Este artigo examina os possíveis impactos que o Ato sobre Decisões Relacionadas a Tratamento de Manutenção da Vida para Pacientes em Casas de Idosos e de Cuidados Paliativos ou ao Fim da Vida na Coréia (ato de fim da vida da Coréia), aprovado pelo legislativo em 2016, sobre o desenvolvimento de comitês de ética de hospitais e serviços de consulta sobre ética clínica na Coréia do Sul. Ética clínica na Coréia não sofreu muito progresso em comparação com outras subdisciplinas da ética biomédica. Enquanto a promulgação desta lei pode dar origem a serviços de ética clínica proveitosos, é possível que práticas usuais e autoridades tradicionais na sociedade coreana entrarão em conflito com as normas da ética clínica. Este artigo examina como os três principais agentes da sociedade coreana – família, governo e profissionais médicos – podem se chocar com normas de estágios de fim da vida em ética clínica, colocando assim obstáculos para o desenvolvimento de comitês hospitalares e serviços de consulta.

Implementasi port knocking dinamis berbasis waktu pada router untuk pengamanan akses SSH

This research proposes a time-based dynamic port knocking technique on Mikrotik routers to enhance SSH access security. The system uses an algorithm for port calculation that changes according to the server’s time, requiring a different knocking sequence for each access session. The technique involves three consecutive knocking stages, where each stage must be passed in order for SSH access to be granted. The results show that this method is effective as a two-factor authentication mechanism, limiting access only to clients who understand the port calculation algorithm. Moreover, this system helps prevent brute-force attacks more efficiently by changing the port every minute, making it more difficult for unauthorized parties to launch an attack. Therefore, this method offers a more dynamic, adaptive, and flexible SSH security solution that can effectively address modern cybersecurity threats

Surface temperature of the exposed silo face as quick indicator of the decomposition process of maize silage

Silage temperature and oxygen concentration are critical parameters for controlling the silage process. Anaerobic condition with lower and stable temperature is necessary for quality silage making. However, when the silo is opened or if there are any failures (e.g. at the cover or at the walls) the anaerobic environment is changed to an aerobic state. That caused intensive decomposition process allied to increase of the temperature in the problematic silage layers. The objective of the current study is to evaluation of infrared thermography technique possibilities for measurement of surface temperature of the maize silage under conditions representative of an exposed face silo, interpretation of measured values and detection of layers and areas with intensive decomposition process

Infrared focal plane performance in the South Atlantic anomaly

Proton-induced pulse height distributions (PHD's) in Si:XX detectors were studied analytically and experimentally. In addition, a preliminary design for a flight experiment to characterize the response of Si:XX detectors to the trapped proton environment and verify PHD models was developed. PHD's were computed for two orbit altitudes for a variety of shielding configurations. Most of the proton-induced pulses have amplitudes less that about 3.5 x 10(exp 5) e-h pairs. Shielding has a small effect on the shape of the PHD's. The primary effect of shielding is to reduce the total number of pulses produced. Proton-induced PHD's in a Si:Sb focal plane array bombarded by a unidirectional 67-MeV beam were measured. The maximum pulse height recorded was 6 x 10(exp 5) pairs. The distribution had two peaks: the larger peak corresponded to 3.8 x 10(exp 5) pairs and the smaller peak to 1.2 x 10(exp 5) pairs. The maximum pulse height and the larger peak are within a factor of two of predicted values. The low-energy peak was not expected, but is believed to be an artifact of inefficient charge collection in the detector. The planned flight experiment will be conducted on a Space Shuttle flight. Lockheed's helium extended life dewar (HELD) will be used to provide the required cryogenic environment for the detector. Two bulk Si:Sb arrays and two Si:As impurity band conduction arrays will be tested. The tests will be conducted while the Space Shuttle passes through the South Atlantic Anomaly. PHD's will be recorded and responsivity changes tracked. This experiment will provide a new database on proton-induced PHD's, compare two infrared detector technologies in a space environment, and provide the data necessary to validate PHD modeling
