Nimonol from Chisocheton macrophyllus (Meliaceae) Seeds and Their Cytotoxic Activity against P-388 Leukaemia Cells

The Chisocheton genus belongs to the Meliaceae family which produces various structures and activities of compounds, such as antimalarial, antimicrobial, antitumor, anti-inflammatory, and cytotoxic. This plant has 53 species that are spread in tropical and sub-tropical forests, including Indonesia. Chisocheton plants have been known as plants that produce limonoids, namely triterpenoid compounds that have been modified to lose four terminal carbons (tetranortriterpenoids). One of the species whose phytochemical reports are still few and interesting for research on limonoid content is Chisocheton macrophyllus. Chisocheton macrophyllus is a tall plant that grows in the rainforest in the northern part of the island of Sulawesi, Indonesia, has the regional name ma aa, gula, pasak lingga, gending, ta suea, bekak, or pithraj tree. This paper will describe a limonoid compound, namely nimonol which has been isolated from Chisocheton macrophyllus. Nimonol is known to have the molecular formula C28H36O5 from a group of havanensin. The structure was determined by spectroscopic methods UV, IR, 1D-NMR (1H-NMR, 13C-NMR, and DEPT), 2D-NMR (1H-1H COSY, HMQC, and HMBC), and mass spectroscopy.
Solution of the 2‐D shallow water equations with source terms in surface elevation splitting form

A vertex‐centred finite‐volume/finite‐element method (FV/FEM) is developed for solving 2‐D shallow water equations (SWEs) with source terms written in a surface elevation splitting form, which balances the flux gradients and source terms. The method is implemented on unstructured grids and the numerical scheme is based on a second‐order MUSCL‐like upwind Godunov FV discretization for inviscid fluxes and a classical Galerkin FE discretization for the viscous gradients and source terms. The main advantages are: (1) the discretization of SWE written in surface elevation splitting form satisfies the exact conservation property (𝒞‐Property) naturally; (2) the simple centred‐type discretization can be used for the source terms; (3) the method is suitable for both steady and unsteady shallow water problems; and (4) complex topography can be handled based on unstructured grids. The accuracy of the method was verified for both steady and unsteady problems, including discontinuous cases. The results indicate that the new method is accurate, simple, and robust.

Towards accurate and consistent force calculation in finite element based computational magnetostatics

Force calculations based on numerical field solutions represent an important step in the design of many electro-magneto-mechanical devices. Ensuring that the calculated forces are as accurate as possible for a given field solution is a requirement for any viable design system. This paper is concerned with the errors encountered in numerical force calculation and methods which avoid them.
Chronic Pain in the ICD-11: New Diagnoses That Clinical Psychologists Should Know About

Background In the 10th revision of the International Classification of Diseases and Related Health Problems (ICD-10), chronic pain was not represented adequately. Pain was left undefined and not recognized as a biopsychosocial phenomenon. Instead, a flawed dualism between psychological and somatic factors was implied. Individual diagnoses were ill-defined and scattered randomly through different chapters. Many patients received diagnoses in remainder categories devoid of meaningful clinical information. Method The International Association for the Study of Pain launched a Task Force to improve the diagnoses for the 11th revision of the ICD and this international expert team worked from 2013-2019 in cooperation with the WHO to develop a consensus based on available evidence and to improve the diagnoses. Results A new chapter on chronic pain was created with a biopsychosocial definition of pain. Chronic pain was operationalized as pain that persists or recurs longer than three months and subdivided into seven categories: Chronic primary pain and six types of chronic secondary pain. All diagnoses were based on explicit operationalized criteria. Optional extension codes allow coding pain-related parameters and the presence of psychosocial aspects together with each pain diagnosis. Conclusion First empirical studies demonstrated the integrity of the categories, the reliability, clinical utility, international applicability and superiority over the ICD-10. To improve reliability and ease of diagnosis, a classification algorithm is available. Clinical psychologists and other clinicians working with people with chronic pain should watch the national implementation strategies and advocate for multimodal and interdisciplinary treatments and adequate reimbursement for all providers involved.
Theoretical calculation of light-induced forces and torques on complex microrotors

In this letter, we propose the new theoretical investigation on the optical forces and torques on complex microrotors. On the basis of R. C. Gauthier’s hybrid ray-wave model, the optical forces and toques on two complex asymmetric micro-objects, the conical microrotor and the helical microrotor, are analyzed. The viscous drag torque is estimated by Stokes flow to obtain the rotational speed. The results of our computation agree well with the previously published experimental results, which indicates that our approach of the optical torque calculation is suitable for other complex microrotors and that the theoretical calculation is very helpful to optimum design of light-driven microrotors.
Village Fund Policy Based Planning Development

Village funds are used for village development through the development of village potential as an effort to increase PAD and the community's economy, including the establishment of BUMDes which aims to manage village assets and can open new job opportunities for village communities. This village fund also requires dedication from the village government but because of the limited capacity of human resources as village fund managers and village heads. Acceleration of village development with the use of village funds can be carried out by utilizing area-based village funds that lead to natural resource management adapted to rural settlements, government services, social services, and economic activities so that village potentials and problems can be mapped and resolved in perspective more comprehensive. The method used in this study is the Participatory Rural Appraisal (PRA) method. This research produces a form of synergistic participation in developing village potential through village fund policies that must be managed and can provide benefits to the community so that it can encourage the realization of village independence and at the same time integrate village potential with all parties, namely the government, community, private sector.

Impacts of Sustainability Performance and Firm Characteristics on Risk and Corporate Value

AbstractThis research investigates the effect of sustainability performance and firm characteristics on risk and corporate value by applying a structural equation model. The focus of the analysis is on Indonesian companies that received sustainability ratings continuously from the Asia Sustainability Reporting Award during the 2018-2019 period. The process involved analyzing secondary data presented in annual and sustainability reports to obtain relevant content for corporate sustainability performance. The findings showed that the improvement of the sustainability performance was able to significantly reduce corporate risk but did not have any influence on corporate value. It was also discovered that large companies with political connections face increased risk, thereby, limiting their ability to enhance corporate value significantly. Moreover, the incorporation of sustainability investment strategies was observed to require business risk management to reduce future environmental and social risks associated with long-term corporate value creation. Keywords:sustainability performance, risk, firm value Dampak Kinerja Keberlanjutan dan Karakteristik Perusahaan Terhadap Risiko dan Nilai Perusahaan AbstrakPenelitian ini mengkaji pengaruh kinerja keberlanjutan dan karakteristik perusahaan terhadap risiko dan nilai perusahaan. Analisis model struktural digunakan untuk menguji perusahaan Indonesia yang secara konsisten menerima peringkat keberlanjutan dari Asia Sustainability Reporting Award pada tahun 2018-2019. Data sekunder berupa laporan tahunan dan laporan keberlanjutan perusahaan dianalisis untuk memperoleh konten yang relevan dengan kinerja keberlanjutan perusahaan. Hasil penelitian menunjukkan bahwa peningkatan kinerja keberlanjutan akan menurunkan risiko perusahaan secara signifikan, namun tidak mempengaruhi peningkatan nilai perusahaan. Perusahaan besar dengan koneksi politik dapat menghadapi peningkatan risiko, namun tidak dapat berkontribusi secara signifikan untuk peningkatan nilai perusahaan. Penggabungan strategi investasi keberlanjutan membutuhkan manajemen risiko bisnis untuk mengurangi risiko lingkungan dan sosial di masa depan untuk penciptaan nilai perusahaan dalam jangka panjang. Kata kunci:kinerja keberlanjutan; risiko, nilai perusahaan
Molecular Abundances and Low-Mass Star Formation. II. Organic and Deuterated Species toward IRAS 16293-2422

Millimeter and submillimeter line surveys of the protobinary source IRAS 16293-2422 are presented in the 230 and 345 GHz windows. In total, 265 lines belonging to 44 molecules and their isotopomers (24 chemically different species) have been detected. Here the data for organic and deuterated molecules are considered; the results for Si- and S-bearing species have been discussed in an earlier paper (Blake et al. 1994). The observations have been analyzed through a combination of rotation diagrams and full statistical equilibrium/ radiative transfer calculations. At least three physically and chemically different components can be distinguished within the 20" (3000 AU) beam. The first component is the warm (T_(kin) ≳ 80 K) and dense [^n(H_2) ≍ (0.5-1) × 10^7 cm^(-3)] gas sampled by Si- and S-containing molecules such as SiO and SO_2. This gas is found to be rich in organic molecules such as CH_3OH, CH_3CN, and H_2CO, as well. It is only 3"-10" in size (500-1500 AU) and most likely represents the interaction of the bipolar outflow(s) with the circumbinary envelope. The second component is the circumbinary envelope itself, which has T_(kin) 40 K and n(H_2) 10^6-10^7 cm^(-3) and is 10"-15" in size (2000 AU). It contains common molecules like CS, HCO^+, and H_2CO. The third component is the colder, lower density outer part of the envelope, which gradually fades into the ambient surrounding cloud core [T_(kin) ≍ 10-20 K; n(H_2)≈(3 × 10^4)-(2 × 10^5) cm^(-3)]. Radicals such as CN, C_2H, and C_3H_2 appear to reside principally in this region. The ambient cloud material is also probed through self-absorbed features in the line profiles of molecules such as HCN, HCO^+, and H^2CO. Beam-averaged abundances over a 20" scale are presented and are compared with those observed in cold dark clouds such as L134N and TMC-1 and with high-mass star-forming cores such as Orion-KL. Remarkably high deuterium fractionation ratios are found, which are more characteristic of hot core regions than of cold, quiescent clouds. As a whole, the chemical and physical regimes that can be distinguished in the low-mass young stellar object IRAS 16293-2422 are qualitatively similar to those found in high-mass star-forming regions, confirming the earlier conclusion that the chemical composition depends more on the age of the object than its mass.
Interstellar scattering toward Cygnus X-3: Measurements of anisotropy and of the inner scale

We present 18 cm wavelength Very Long Base Interferometry (VLBI) observations of Cyg X-3 obtained 1989 June 6 along with 18 and 20 cm Very Large Array (VLA) A-array data obtained 1985 February 8. In both data sets, the flux density was relatively high, and the intrinsic source size small compared to the scattering, ideal conditions for a detailed study of interstellar scattering. We find that the scattering disk is anisotropic, with an axial ratio 1.31 +/- 0.02 along position angle 52.0 deg +/- 1.5 deg. This is the first unambiguous measurement of anisotropic scattering in the interstellar medium. We also find a significant break in the phase structure function, the first measurement of a break in any source. The data exclude a steep turbulent spectrum, but are consistent with a shallow turbulent spectrum with an inner scale of 300 km, with a net uncertainty of approximately 50%. We tentatively identify the scattering plasma with the H II region DR 11, for which we estimate a visual extinction of 4 mag, and an emission measure toward Cyg X-3 of 6000 cm(exp -6)pc. We make the case that DR 11 is part of a shell of H II regions centered on the Cyg OB2 association (which is approximately 1.8 kpc distant) that is 2 deg (60 pc) in radius and expanding at 10 km/s. Our inner scale is consistent with that expected for an H II region, and the amount of scattering is consistent with the emission measure. We discuss how the anisotropy can be used to confirm the identification with DR 11 and to distinguish between different models of turbulence by comparison with measurements of the polarization of starlight along the line of sight.
Implementation of PBL and IBL Models Assisted by Video Media to Improve Critical Thinking Skills

Teaching social science in elementary schools is not only conveying theories but also real forms of implementation and problems that often arise in the daily environment. This is be able to develop students' critical thinking in reconstructing events and the values contained therein. However, the media and learning methods used today have not been able to improve students' critical thinking skills. This study aims to analyse the improvement students' critical thinking skills through the application of collaboration between PBL and IBL models using video. The research subjects were elementary school students who were in grade 5, consisting of 30 students. The instrument used for data collection in this study was a descriptive description test. The data analysis technique used in this research is descriptive statistical technique. This research design uses classroom action research which consists of three cycles. The results showed that critical thinking skills increased in each cycle. In the first cycle, 50.33% of critical thinking skills in the second cycle increased to 69.83% and in the third cycle increased to 78.38%. So the conclusion from the results of this study is that the implementation of PBL and IBL models through video media is proven to be able to improve students' critical thinking skills, thus, it is proven that the integration between innovative learning models and learning media contributes positively to the improvement of students' abilities and competencies.
Derivation of Green's Functions for Paraxial Fields of a Wedge with Particular Anisotropic Impedance Faces

Abstract A dyadic Green's function of a wedge with anisotropic impedance faces, excited by an electric dipole source, is derived for the paraxial region where the source and observation points are in proximity to the apex but widely separated. The principal anisotropy axis is the edge axis, and surface impedances parallel and transverse to this axis are considered. Following a “separation of variables” derivation, final dyadics involve eigenfunction solutions over an angular wave number and a longitudinal spectral integral, which is evaluated asymptotically assuming that k|z – z′| is large. It is observed that derived forms reveal three distinct scattering mechanisms: edge-guided waves, surface waves, and guided waves in the classical sense. Numerical simulations limited to paraxial region show that edge-guided and guided-wave terms are dominant at points away from the wedge surface, whereas surface waves are dominant near impedance surfaces. Both capacitive, inductive, and mixed (one face capacitive and the other inductive) reactive surface impedances are numerically analyzed. The resulting expressions can be used in the analysis of antennas located near the apex of a wedge and electromagnetic scattering from artificially hard and soft surfaces.
Design and measurement of cost-balanced and electronic-efficient embroidered textile electrodes

Abstract In this work, different textile electrodes are assessed and a novel measurement system for their characterization is presented. Those electrodes are made of a paraffin-coated conductive yarn embroidered into a textile substrate following two distinct embroidering techniques with up to six different geometry characteristics for each one. To evaluate the sensor behaviour, the impedance has been measured by means of an LCR meter at 50 kHz at atmospheric conditions (25 °C and about 40% relative humidity). The results obtained were as follows. First, the application of a paraffin wax coating to the conductive yarn enhances better test results and eases the production process. Second, the proposed measurement system provides much more consistent results in comparison with other standard techniques already in use. Finally, higher densities of conductive yarn obtained lower resistance values, and so impedance, rather than other configurations.
Concept Understanding, Environmental Care Character, and Student Responses in Elementary School Thematic Subjects

Students' understanding and the character of students' environmental care still need to be developed. This study aims to analyze the differences and relationships of the variables of concept understanding, environmental care character, and student responses in elementary schools on thematic subjects. This study uses mixed research methods designed with an explanatory design. Explanatory design is carried out in several stages of research, first by collecting data, second by analyzing the data and third by formulating the results of the analysis quantitatively, then proceeding with data collection, analyzing and formulating qualitative data, and ending with interpreting the research results. Data collection in this study used instruments in the form of observation sheets and questionnaires. Data analysis was carried out qualitatively and quantitatively. The results of the t-test and correlation test on the variables of conceptual understanding, environmental character, and student responses in elementary schools on thematic subjects can be said to be good but need to be improved optimally so that these variables are beneficial for students. The conclusion of this study is that there is a comparison of concept understanding, environmental care character, and response in two elementary schools on thematic subjects and there is a relationship between concept understanding, environmental care character, and student responses in two elementary schools on thematic subjects.
Peripheral implications of national innovation: insights from the Israeli experience

ABSTRACT Despite the growing importance of innovation and technological advancement in stimulating economic growth, their impact on peripheral regions is not completely clear. Two contradictory effects are analysed in the literature: new growth opportunities and the tendency toward geographical concentration of innovation. This study contributes to the literature by distinguishing between the impact of the national innovation trend on the economic structure of the periphery (demand side) and its impact on the resident labour force (supply side), occupied in or out of the periphery, and by adopting and adapting the concept of a knowledge-based economy as a major measure. Using ‘best-fitted’ regressions on the last two decades in Israel, we found a discrepancy between demand and supply. The economic structure of the periphery (demand) shows some adaptation to national innovation trends in terms of an increased share of high-skilled occupations; however, the demand does not match the improvement of the local labour force supply. The results highlight the need for further investigation into the imbalance between the impacts on the labour demand/supply balance, ecosystem factors that influence the lower flexibility of the local economic structure, and the existence of a regional market failure.
Analysis of local influence in geostatistics using Student's t-distribution

This article aims to estimate parameters of spatial variability with Student's t-distribution by the EM algorithm and present the study of local influence by means of two methods known as likelihood displacement and Q-displacement of likelihood, both using Student's t-distribution with fixed degrees of freedom (ν). The results showed that both methods are effective in the identification of influential points.
Service impact: how patients use mental health and medical services before and after psychodynamic psychotherapy

Many patients referred for psychodynamic psychotherapy are also seen by other services. Due to the complex interplay between psychological distress, physical symptoms and care-seeking behaviour, engagement with a psychotherapy department has the potential either to increase or decrease use of other services. This service evaluation compared 268 patients’ service use in the year preceding and following contact with an NHS psychodynamic psychotherapy department using t-tests. There were no significant changes from before therapy to afterwards for the sample as a whole. However, for sub-groups who made regular use of services at baseline, a full course of psychotherapy (16+ sessions) was associated with a statistically significant reduction in outpatient contacts, both for mental health (N = 32, mean 11.69 appointment per year pre-therapy vs 5.16 post-therapy, p = 0.01) and medical services (N = 23, from mean 9.65 to 3.00, p < 0.01). No compensatory changes were found in either A&E or inpatient contacts, suggesting this represents an overall reduction in service use. Due to the study design, it was not possible to establish causality; there may be other reasons for this observed reduction such as natural illness course. These findings tentatively support the existing literature that psychodynamic psychotherapy is associated with a reduction in use of wider services.
