Exploring the socio-economic situation of plantation villagers: A case study in Myanmar Bago Yoma

Massive scale plantation forestry in Myanmar began in the early 1980s as a drastic measure to fulfil the increasing demand for timber and to prevent the conversion of deteriorated forestland to agricultural land. Myanmar Forest Department is recruiting shifting cultivators, establishing plantation villages and applying the taungya method in establishing teak plantations. From the very beginning, there was an argument about whether the project is creating forest protective groups or forest destructive groups. A key determinant to that question from the researcher point of view is the socio-economic situations; knowing the present situation of the plantation villagers can help to understand the forest management practices. Interview surveys were carried out in three villages in Bago Yoma, the main region of the special teak plantation program, to examine the current economic benefits to plantation villagers. Questions were designed mainly to explore the incentives for people participation and the socio-economic situations of the plantation villagers. Principal component analysis was used to analyze the collected data. It was found that local people are willing to participate in the initial establishment of plantations. However, all the incentives relating to the project are temporary, with no long-term consideration for taungya farmers, which jeopardizes the plan to create forest protective groups. It is concluded that the time has come for the Myanmar Forest Department to change its main aim of earning foreign exchange from establishment of teak plantations through the taungya method to redressing deforestation through people participation based on rural socio-economic development

Axion-Dilatonic Conformal Anomaly from Ads/CFT Correspondence

We discuss general multidimensional axion-dilatonic AdS gravity which may correspond to bosonic sector of Gibbons-Green-Perry (compactified) IIB supergravity with RR-scalar (axion). Using AdS/CFT correspondence the 4d conformal anomaly on axion-dilaton-gravitational background is found from SG side. It is shown that for IIB SG with axion such conformal anomaly coincides with the one obtained from QFT calculation in ${\cal N}=4$ super Yang-Mills theory conformally coupled with ${\cal N}=4$ conformal SG. Brief discussion on possibility to apply these results for gauged SGs is also presented.Comment: LaTeX file, 10 page

Quality control of photosystem II: The molecular basis for the action of FtsH protease and the dynamics of the thylakoid membranes

Abstract The reaction center-binding D1 protein of Photosystem II is damaged by excessive light, which leads to photoinhibition of Photosystem II. The damaged D1 protein is removed immediately by specific proteases, and a metalloprotease FtsH located in the thylakoid membranes is involved in the proteolytic process. According to recent studies on the distribution and organization of the protein complexes/supercomplexes in the thylakoid membranes, the grana of higher plant chloroplasts are crowded with Photosystem II complexes and light-harvesting complexes. For the repair of the photodamaged D1 protein, the majority of the active hexameric FtsH proteases should be localized in close proximity to the Photosystem II complexes. The unstacking of the grana may increase the area of the grana margin and facilitate easier access of the FtsH proteases to the damaged D1 protein. These results suggest that the structural changes of the thylakoid membranes by light stress increase the mobility of the membrane proteins and support the quality control of Photosystem II.

Quantum computing quantum Monte Carlo with hybrid tensor network toward electronic structure calculations of large-scale molecular and solid systems

Quantum computers are expected to solve the problems for quantum chemistry and materials science with higher accuracy than classical computers. Quantum computing quantum Monte Carlo (QC-QMC) is a method that can be combined with quantum algorithms such as variational quantum eigensolver (VQE) to obtain the ground state with fewer quantum resources and higher accuracy than either VQE or QMC alone. In this study, we propose an algorithm combining QC-QMC with hybrid tensor network (HTN) to extend the applicability of QC-QMC for the system beyond the size of a single quantum device, and we named the algorithm HTN+QMC. For HTN with the structure of a two-layer quantum-quantum tree tensor, the proposed algorithm for an $O(n^2)$-qubit reference wave function (trial wave function) in QMC can be performed by using only a $n$-qubit device excluding ancilla qubits. Full configuration interaction QMC is adopted as an example of QMC, and the proposed algorithm is applied to the Heisenberg chain model, the graphite-based Hubbard model, the hydrogen plane model, and MonoArylBiImidazole (MABI). The results show that the algorithm can achieve energy accuracy several orders of magnitude higher than either VQE or QMC alone. In addition, the energy accuracy of HTN+QMC is as same as QC-QMC when the system is appropriately decomposed. These results pave the way to electronic structure calculation for large systems with high accuracy on current quantum devices.Comment: 27pages, 19 figures, 5 table

Association between intraoperative end-tidal carbon dioxide and postoperative nausea and vomiting in gynecologic laparoscopic surgery

Gynecologic laparoscopic surgery has a high incidence of postoperative nausea and vomiting (PONV). Studies suggest that low intraoperative end-tidal carbon dioxide (EtCO₂) is associated with an increased incidence of PONV, but the results have not been consistent among studies. This study investigated the association between intraoperative EtCO₂ and PONV in patients undergoing gynecologic laparoscopic surgeries under general anesthesia. This retrospective cohort study involved patients who underwent gynecologic laparoscopic surgeries under general anesthesia at Kyoto University Hospital. We defined low EtCO₂ as a mean EtCO₂ of < 35 mmHg. Multivariable modified Poisson regression analysis examined the association between low EtCO₂ and PONV during postoperative two days and the postoperative length of hospital stay (PLOS). Of the 739 patients, 120 (16%) had low EtCO₂, and 430 (58%) developed PONV during postoperative two days. There was no substantial association between low EtCO₂ and increased incidence of PONV (adjusted risk ratio: 0.96; 95% confidence interval [CI] 0.80–1.14; p = 0.658). Furthermore, there was no substantial association between low EtCO₂ and prolonged PLOS (adjusted difference in PLOS: 0.13; 95% CI − 1.00 to 1.28; p = 0.816). Intraoperative low EtCO₂, specifically a mean intraoperative EtCO₂ below 35 mmHg, was not substantially associated with either increased incidence of PONV or prolonged PLOS

Studi Sistem Akustik Pada Gereja Katolik Santa Maria Tak Bercela Surabaya

The church is a building that has an image of God\u27s glory so that through space design elements, sacred atmosphere can formone through acoustics. The church has an unique acoustic because the church has two activities, namely speech and music. Santa Maria Tak Bercela Catholic Church Surabaya adjacent to Santa Clara School Surabaya, which at certain hours of the atmosphere will be very crowded church. With the help of Sound Level Meter, the background noise is known and the power of the sound source at this church. Reverberation time is calculated by manually sabine and computerize using program Autodeks Ecotect Analysis 2011. Having in mindthe results of the calculation of reverberation time in the field was 0.79-0.88 seconds, the church should be optimized with the goal of achieving the optimum reverberation time is 1. 4 seconds and the sound proofing leaks, by using materials such as insulation yumen board, glasswoll, acrylic, curtains, glass in sealant, rubber on the doors and closing the door hole
