Copper Nanopowders

This work researches the impact of the temperature of compacted copper nanopowder on the amperage of the current flowing through the nanopowder sample. It was determined that upon reaching its oxidation temperature (~ 1900C), the copper nanopowder started conducting electricity, and at 280-320°C electric breakdown of sample was occurring. This is caused to irreversible processes taking place in nanomaterials during heating, such as sintering and mass-transfer, those processes leading to the formation of conductivity channels. This speaks in favor of an evident dependency between copper nanopowder conductivity and the chemical transformations taking place in it; this allows for recommending this research method for instant diagnostics of copper nanopowders.

This study aims to obtain a description related to the learning of PAI by using ICT and how the impact of the use of ICT on PAI learning systems in the classroom. The research method uses a qualitative approach in the integrated Islamic high school Ummul Quro Bogor, West Java. The results showed that a) there were four stages of using ICT in the learning process, namely; emerging, applying, integrating dan transforming. PAI teachers are already at the integrating stage. In other words, ICT has been integrated into the PAI learning curriculum. b) supporting factors for the use of ICT are the existence of ICT support facilities, the availability of qualified educators, the commitment of the school to implement ICT in every PAI learning. c) Inhibiting factors in the use of ICT are aspects of financing ICT facilities require a large budget. Some elderly teachers have difficulty using ICT in the learning process. Besides, the internet network is unstable. d) The impact of the use of ICT is very significant on PAI learning process. e) the existence of ICT devices not only as a support but already as an important component in the education system. The research led to the recommendation of the need for government support in the form of concern for ICT in terms of policies, facilities, workforce, budget, and organizing training in the use of ICT for PAI teachers to improve their professionalism. Therefore, further research is suggested regarding the effectiveness of the use of ICT in the learning process of PAI.

Development of village fund management is very much needed by the community so that it can be enjoyed by all levels of society in the villages. The seriousness of the government in developing villages is evidenced by the start of allocation of the Village Fund budget for 2015. The allocation of the Village Fund is mandated by Law (Law) Number 6 of 2014 concerning Villages and Government Regulation (PP) Number 6 of 2014 concerning Village Funds Sourced from STATE BUDGET. The regulation explained that the administration of the village government adheres to the principle of decentralization and the task of assistance. The principle of decentralization raises village internal funding (Desa APBD), while the principle of co-administration provides an opportunity for Villages to obtain funding sources from the government above it (APBN, Provincial APBD, Regency / City APBD). This study aims to observe what the development of village funds looks like, how they are implemented and the impact of the use of village funds in supporting development activities and community empowerment. The research method used is a qualitative research method that relies on observing places, actors and activities in Konawe Selatan Regency, Southeast Sulawesi Province, which was chosen as a case study. Initial observations show that the Village Fund does not have significant results in improving the welfare of the community. These indications are evident in the welfare of the community which has not improved with the existence of the village fund. Therefore it is necessary to develop a good management of village funds to improve the welfare of rural communities, especially in Konawe Selatan District. The output to be achieved is the scientific publication with ISSN Online and the level of technological Readiness that will be achieved 1-3.

Coumarins are natural 1,2-benzopyrones, present in remarkable amounts as secondary metabolites in edible and medicinal plants. The low yield in the coumarins isolation from natural sources, along with the difficulties faced by the total synthesis, make them attractive for biotechnological studies. The current literature contains several reports on the biotransformation of coumarins by fungi, which can generate chemical analogs with high selectivity, using mild and eco-friendly conditions. Prompted by the enormous pharmacological interest in the coumarin-related compounds, their alimentary and chemical applications, this review covers the biotransformation of coumarins by filamentous fungi. The chemical structures of the analogs were presented and compared with those from the pattern structures. The main chemical reactions catalyzed the insertion of functional groups, and the impact on the biological activities caused by the chemical transformations were discussed. Several chemical reactions can be catalyzed by filamentous fungi in the coumarin scores, mainly lactone ring opening, C3-C4 reduction and hydroxylation. Chunninghamella sp. and Aspergillus sp. are the most common fungi used in these transformations. Concerning the substrates, the biotransformation of pyranocoumarins is a rarer process. Sometimes, the bioactivities were improved by the chemical modifications and coincidences with the mammalian metabolism were pointed out.

The aim of this study was to determine the impact of socio-demographic variables on consumer attitudes towards food with a reduced sugar content. The study was conducted in educational institutions, a university and educational centers for seniors located in the Warmia-Mazury, using a survey research method, indirect technique (an original interview questionnaire). In total, 750 respondents were interviewed. The majority of respondents, regardless of socio-demographic characteristics, assesses the health benefits of the sugar content reduction as large and rather large. Despite this, a relatively small portion of respondents, varied by gender and age, used in their diets sugar substitutes and was interested in products with a reduced sugar content. According to the most of the respondents, lowering the sugar content of a product affects the deterioration of its flavor.

The aim of our research was to study the impact and purpose of the reporting on socially responsible conduct on the success of corporate operations. The data and information were gathered with the quantitative research method, whereas the instrument for gathering them was a questionnaire that was distributed among 759 large and medium sized organisations from the field of market services in the Republic of Slovenia. We have established that activities aimed at socially responsible conduct are directly connected with the success of corporate operations, especially the revenue (p = 0.001), the profit of a company (p = 0.000), operational growth (p = 0.007) and operational economy (p = 0.002), and are typical for organizations with a larger number of employees (p = 0.032). In this regard, the real estate and construction market activities received the lowest scores. Research results provide theoretical as well as practical benefits for everyone dealing with the planning, implementation and control of sustainable development, as well as socially responsible conduct within the organization.

The current analysis deals with radiative aspects of magnetohydrodynamic boundary layer flow with heat mass transfer features on electrically conductive Williamson nanofluid by a stretching surface. The impact of variable thickness and thermal conductivity characteristics in view of melting heat flow are examined. The mathematical formulation of Williamson nanofluid flow is based on boundary layer theory pioneered by Prandtl. The boundary layer nanofluid flow idea yields a constitutive flow laws of partial differential equations (PDEs) are made dimensionless and then reduce to ordinary nonlinear differential equations (ODEs) versus transformation technique. A built-in numerical algorithm bvp4c in Mathematica software is employed for nonlinear systems computation. Considerable features of dimensionless parameters are reviewed via graphical description. A comparison with another homotopic approach (HAM) as a limiting case and an excellent agreement perceived.
