Photofragmentation of carbonyl sulfide (Ocs) following core-shell photoexcitation and photoionization

Mass spectroscopy is used to study the formation of cations and anions after photoexcitation and photoionization of OCS in the vicinity of the S 2p, C 1s and O 1s thresholds. Singly charged cations are produced predominantly at the pi* and Rydberg resonances while dications are major products of dissociative channels above the thresholds. At the S 2p threshold, broad Franck-Condon regions observed for Rydberg excited states manifests an apparent change in molecular bond lengths upon the excitation of S 2p electrons to Rydberg orbitals. Neutral dissociation of the pi*3/2, pi*1/2 and 4S 3/2 excited states is found to compete efficiently with electronic relaxation via Auger processes. The observation of SO+ ions at the pi* resonance indicates a strong Renner-Teller vibronic coupling of bending vibrations in the 4pi* excited states with a bent equilibrium geometry. The anions (S-, C- and O-) are observed both below and above the thresholds. The fact that the anion production is suppressed at shape resonances allows the anions to serve as a suggestive and complementary tool for identifying above-threshold structures in the OCS photoabsorption spectra. Post-collision-interaction effects in OCS and locality of the lowest unoccupied molecular orbital 4pi* at the sulfur atom are also evidenced in the anion spectra

Characteristics of Simulated Workplace Neutron Standard Fields

This paper presents the development of simulated workplace neutron standard fields at the Institute for Nuclear Science and Technology with the 241Am-Be source moderated by polyethylene spheres with diameters of 15 cm and 30 cm. The characterization of the standard fields (in terms of neutron fluence rates and neutron ambient dose equivalent rates) was performed using Bonner sphere spectrometer system together with MAXED and FRUIT unfolding codes. The related quantities such as neutron dose equivalent-averaged energies and fluence-to-ambient dose equivalent conversion coefficients were also determined. The discrepancies of values are satisfied the standard uncertainty criteria as recommended by the International Standard Organization 12789 series. It implies that the simulated workplace neutron standard fields can be applied in the practical works for calibration purposes

The result shows the efficiency of recovery of recyclables from household wastes in Dau Tieng town is quite high with 77.99 %. The major component of the recyclables consists of plastic, glass, paper, aluminum, iron and steel. The amount of recyclable materials lost in the recovery process in studying area is 258.52 kg/day, equivalent to 1,310,696 VND each day

From Laborer to Learner: The Experiences of Former Factory Workers in a Developmental Education Program

This study reports on a qualitative, case study of a learning community approach to developmental education for dislocated workers. The findings suggest that participants rework a sense of themselves as learners, mediated by their experience of liminality and the emergence of communitas within the group

A STUDY ON PROBLEMS IN SPEAKING OF ENGLISH-MAJORED FRESHMEN AT TAY DO UNIVERSITY AND SOME SUGGESTED SOLUTIONS

In this globalization era, there have been drastic changes taking place all over the world. People’s desires are fulfilled when they clearly express their ideas and opinions to others. Thus, they need to learn speaking skills in order to fulfill their ambitions, desires, and goals. However, it is so difficult for students to master this skill because they encounter some common problems when speaking. Therefore, the research entitled "A study on problems in speaking of English-majored freshmen at Tay Do University and some suggested solutions" was carried out in order to identify common problems in English speaking of English majored freshmen at Tay Do University and provide some suggested solutions. In this study, questionnaires and interview papers were used as the main instruments to collect the data. The participants were 80 English-majored freshmen in the two classes of English course 16 including 16A and 16B at Tay Do University. The study's findings revealed that freshmen majoring in English had several common problems with vocabulary, pronunciation, grammar, the influence of mother tongue, and psychology in speaking. It is expected that this study will assist English-majored freshmen at Tay Do University in recognizing and overcoming obstacles in the process of speaking.  Article visualizations

Nursing Education in Indonesia: Todays and Future Role

Nursing Education in Indonesia: Todays and Future Trends. Shanghai International Nursing Conference, November 2009, Shanghai, China Abstract Societal and health care changes have presented many challenges for nursing. The challenge for nursing education is to ensure that professional education remains relevant and keeps in track with the needs of the market. These challenges include globalization, changes of patient characteristics, impacts of technology information, migration, future tendencies and other current issues in nursing development in Indonesia. A desk study was performed from relevant published materials. Literature was reviewed from means and databases of the International Council of Nurses, Indonesian Nurses National Association and electronic journals. The aim of this paper is to consider possible future societal and healthcare changes and how they may impact the development of future nursing education. A clear understanding of these factors is critical to face tomorrow challenges within global context

Informações contábeis e retornos de ações no mercado de ações do Vietnã: abordagem de aprendizado de máquina

This paper studies the relationship between accounting information reflected in financial statements and stock return in Vietnam Stock Market. The authors propose a research model to define the relationship. Besides, machine learning algorithms are used in researching and forecasting, with data obtained from observed firms during the period from 2009 to 2020. Research results show that gradient boosting algorithm has the best self-reporting performance and finan-cial ratios also have great impact on stock returns, including operating income growth, stock earnings volatility, dividend yield, earnings before tax-to-equity ratio, cash holding ratio, and accrual quality. Based on the research results, the authors make some recommendations for investors, firms, and policy makers.Este artículo estudia la relación entre la información contable reflejada en los estados financieros y el rendimiento de las acciones en el mercado de valores de Vietnam.

A characterization of the algebraic degree in semidefinite programming

In this article, we show that the algebraic degree in semidefinite programming can be expressed in terms of the coefficient of a certain monomial in a doubly symmetric polynomial. This characterization of the algebraic degree allows us to use the theory of symmetric polynomials to obtain many interesting results of Nie, Ranestad and Sturmfels in a simpler way.Comment: 14 page

Navigating Complexity: Stakeholder Perspectives on Marine Conservation and Sustainable Policies

Encouraging a shift towards an “eco-surplus” mindset among stakeholders is essential for achieving long-term sustainability and safeguarding marine ecosystems. This mindset involves reframing environmental protection not as a hindrance but as a vital investment in the future. By recognizing the intrinsic value of conservation efforts, stakeholders can ensure the availability of ecosystem services crucial for human societies. Policymakers play a crucial role in this endeavor, engaging with local communities to cultivate a shared sense of environmental responsibility. Through grassroots initiatives like education and awareness campaigns, stakeholders can develop a collective commitment to marine conservatio

Macroeconomic factors and stock prices – A case of real estate stocks on Ho Chi Minh stock exchange

This study investigates the relationship of selected economic factors such as inflation rate, 10-year Government bond yields, GDP growth rate, exchange rate, and stock trading volumes and real estate stock price of 38 real estate companies listed on HOSE in period 7 years, from January 2009 to September 2015.The study found that 3 economic factors (inflation rate, GDP growth rate, and exchange rate) impact significantly on real estate stock prices; but the relationship between 10-year Government bond yield and trading volume, and real estate stock prices was not found. The research’s results imply that these factors should be taken into account as predictors of the movement of real estate stock price in Vietnamese stock market
