Background: The literature indicates that chronic obstructive pulmonary disease (COPD) affects cardiac autonomic control. In this study, we conducted a literature review in order to investigate the heart rate variability (HRV) in COPD subjects. Methods: A search was performed in Medline database, using the link between the keywords: "autonomic nervous system", "cardiovascular system", "COPD" and "heart rate variability". Results: The search resulted in a total of 40 references. Amongst these references, the first exclusion resulted in the barring of 29 titles and abstracts, which were not clearly related to the purpose of review. This resulted in a total of 11 articles that were then read and utilized in the review. The selected studies indicated that there is significant reduction of HRV in patients with COPD, characterized by reduction of indices that assess parasympathetic activity in addition to dealing with the global autonomic modulation. We also established that supervised exercise can reduce these harmful effects in COPD patients. Also, it was reported that the use of non-invasive ventilation in these patients may contribute to the improvement of respiratory symptoms, with no impairing, and may even induce positive responses in cardiac autonomic regulation. Conclusion: The studies indicate a need for further investigations to guide future therapies to improve the treatment of cardiovascular system in the respiratory diseases. © 2014 Roque et al.;licensee BioMed Central Ltd.

The frequency of human-tapanuli orangutan (Pongo tapanuliensis) conflict has been increased with the widespread on degradation and fragmentation at Batangtoru Forest, South Tapanuli Regency. Orangutans often come on community lands to look for food, especially while the durian fruit season. This study aims to obtain information on socio-economic characteristics and public perception index to mitigate on human-tapanuli orangutan conflict around the Dolok Sipirok Nature Reserve, South Tapanuli Regency. Data was collected using a questionnaire distribution, interviews and descriptive observations, starting from October 2019 to January 2020. Respondents were selected by purposively sampling method, i.e. people had met and interacted with orangutans as many as 61 respondents from three villages. Data analyzed using frequency tables, likers scale and spearman rank correlation. The results showed that the community is Muslim majority, productive age, education below senior high school, farmers and income below IDR. 4,000,000. The public perception has declared orangutans as animals that consume community plants. They will drive away the orangutans found in processed land. The perception of conflict mitigation has strongly agreed with the program that must be done including providing compensation for losses, increasing patrol programs, developing local wisdom and building corridors in state forests.

The purpose of this study is to uncover and analyze the role of local wisdom of the community for development in Nagari Paru, Sijunjung Regency, West Sumatra. This study used a quantitative and qualitative method to figure out the role of Rimbo Larangan as one of the local wisdom applied in the community. The results of this study indicate that: the existence of the local wisdom of the community in the form of the Rimbo Larangan originated from forest destruction that occurred several years ago so that it has an impact on people's lives. The community in Nagari Paru has a perspective that the environment needs to be treated properly so that it can produce benefits in the form of improving health, happiness and increasing nagari development. The community is accustomed to managing the environment, because there is a recommendation from the Niniak Mamak, and it must be improved because it is important to their life. Since people in Nagari Paru are generally farmer, who need water every day for their fields and life, so the availability of water become their main concern. Although maintaining the Rimbo Larangan in Nagari Paru is still an agreement but it is effective enough to bind the community not to cut wood in the jungle, meaning that the community is accustomed to maintaining the jungle for life. Quantitative analysis showed a significant role of the local wisdom particularly in the nagari development as confirmed by the regression equation. © Published under licence by IOP Publishing Ltd.

Aluminium nano-powder has a small particle size, large specific surface area, and high surface energy, therefore when using it, the risk of fires or explosions is high. In this study, synchronous thermal analyser was used to determine the thermal reaction characteristics of aluminium nano-powder for various oxygen and nitrogen mixtures. The results showed that the oxidation behaviour of aluminium nano-powder could be considered to occur in four stages, according to the characteristic temperature points and polymorphic phase changes. Under experimental heating rates of 5, 10, 15, and 20 K/min, the mass gain and thermal effects of the samples were tested, and also for different oxygen concentrations of 9, 15, and 21 vol%. Changes in the microstructure of the samples were analysed. Oxide layer thickness was found to increase as temperature increased, and this trend was the same for mass change. Surface morphology images of the aluminium particles exhibited agglomeration, melting deformation, rupture, and fragmentation at the different pretreated temperatures of 500, 650, 800, and 900 °C. The results of this study could be used as a basis for exploring oxidation kinetics, and had significance for explosion-proofing technology, particularly with respect to aluminium nano-powder. © 2022 The Institution of Chemical Engineers

The doping process of TiO₂ using a combination method, sol-gel and hydrothermal, has been conducted. The presence of anatase and rutile phase of TiO₂ and doped TiO₂ has been confirmed using UV-DRS, XRD, Raman spectroscopy, and EPR. The Nitrogen-doped TiO₂ (N-TiO₂) showed the highest photoactivity in the powder form than the as-prepared TiO₂ (rutile), anatase and Vanadium-doped TiO₂ (V-TiO₂). The influence of pH during the preparation of N-TiO₂ showed that pH gives a big effect to the morphology and photoactivity of the photocatalyst. The N-TiO₂ at pH 2 showed higher photoactivity than N-TiO₂ at pH 4 and it also showed a fine morphology. The N-TiO₂ also showed the highest photoactivity when it was immobilized in the DPNR matrix. After being immobilized, the photoactivity of the as-prepared photocatalyst was decreased to be 0–30%. © 2019, © 2019 The Author(s).

In any organization, the appropriate use of information systems will have an impact on the effectiveness of day-to-day operations. To find out how the performance of an information system is necessary to do an evaluation of the implementation of which has been run. This study evaluates the implementation of information systems in the Maternity Hospital St. Yosef. By adopting PIECES framework as an evaluation, primary data collection is done through questionnaires distributed. Of the some respondents who collected the data used factor analysis to get factors and indicators affect the successful implementation of system and get right model for evaluation of the Maternity Hospital in St. Joseph. The results showed that the factor of ease use and suitability to needs of a positive effect on the success, while reliability of system negatively affect the success. On a scale of 0-100 obtained an un-expected value of system performance is at 45.75 and the expected value of performance of the system is equal to 83.77. © Published under licence by IOP Publishing Ltd.

A compact electromagnetic multi-resonator is presented in this paper using a new technique for chipless RFID tag data encoding. Employing Archimedean spirals, the information is applied into the spectral signature shifting resonant frequencies in several positions. The multi-resonator tag proposed operates in microwave band (between 3.0-7.0GHz) and has a coding data capacity of up to 100 decimal numbers for two resonant frequencies. The simulated and measured results show a good concordance and a great perspective to use in low-cost RFID chipless tag applications. © 2015 IEEE.
