Solar-to-Pharmaceutical Raw Material Production: Photoelectrochemical Naphthoquinone Formation Using Stabilized BiVO4 Photoanodes in Acid Media

The Swiss forest- and timber industry has detailed five key development areas for the coming years. These are to increase raw material production from the current annual level of 4.5 million cubic metres of timber to 6 million; to increase net product throughout the whole timber chain; to open up new markets for timber and timber products; to increase entrepreneurial competitiveness; and to make communication channels more professional, by ensuring that the end consumer market is given consistent information. The clear outlines of the Confederation's follow-on programme for timber promotion coincide to a large extent with these goals. This marks a good starting point for real co-operation between the Confederation and the Swiss timber industry.

This article describes the hazards and causes of VOCs as well as the state of VOCs. It is the main culprit in the production of VOCs, which is the main culprit of the production of VOCs source materials in automobile, and analyzes the production of VOCs in the raw material production process from the source. Finally, proposed reduction measures from three aspects of the raw materials, production, management.

The Creation

This study aimed to separate the wood production in regions and provinces of Turkey into homogeneous groups based on similarities by using the country’s wood production figures for 2013 and 2018. Within this context, the hierarchical Ward’s and non-hierarchical K-means clustering methods were used comparatively. Clustering analyses of 2 to 6 in number were performed via both methods, and the same regions mostly fell into the same cluster groups, although in different cluster combinations. The results showed that some provinces with rich forest areas did not produce enough wood. It was observed that these provinces were in the same clusters with provinces having a low amount of forest areas and low wood production. Over the five-year period, very few provinces and regions differed in line with the previous development plans. The creation of a spatial database for wood raw material production using the findings obtained in this study will contribute to the development of operational inventory methods that can be included in long- and medium-term forestry plans.

Basin Region

Examining the Late Woodland (1500-450 BP) quarry/workshop site of Davidson Cove, located in the Minas Basin region of Nova Scotia, a sample of debitage and a collection of stone implements appear to provide correlates to the novice and raw material production practices. Many researchers have hypothesized that lithic materials discovered at multiple sites within the region originated from the outcrop at Davidson Cove, however, little information is available on lithic sourcing of the Minas Basin cherts. Considering the lack of archaeological knowledge concerning lithic procurement and production, patterns of resource use among the prehistoric indigenous populations in this region of Nova Scotia are established through the analysis of existing collections. By analysing the lithic materials quarried and initially reduced at the quarry/workshop with other contemporaneous assemblages from the region, an interpretation of craft-learning can be situated in the overall technological organization and subsistence strategy for the study area.

Research Questions

The aim of the paper is to identify elements of seasonality in supply and demand in the liquid biofuels sector in Poland and Germany. An additional purpose is to present forecasts for selected aggregates until 2020. Two research questions have been formulated for their implementation: (1) is biofuel production in Poland higher in spring or summer (due to the seasonality of agricultural raw material production) than e.g. in winter?; (2) Is the consumption of biofuels seasonal in both countries? The research applies quarterly data for the following aggregates from the biofuels sector: for Poland – production and sale of biofuels in the quarters of 2006-2018, for Germany – biofuel consumption in the quarters of 2007-2017, import and export of bioethanol in the quarters of 2007-2015, import and export of esters in the quarters of 2007-2017. The work focuses on identifying seasonal fluctuations in order to identify purified seasonality indicators, so that it is possible to present forecasts for the biofuels sector. The research conducted in the article leads to the conclusions that, in the liquid biofuels sector, in Poland and Germany, there are elements of seasonality, especially in the field of sales / consumption of biofuels, which in turn is the effect of the changing demand for traditional fuels in which liquid biocomponents are admixed or (less often) used separately as fuel. Differences in the values of variables in Poland and Germany in quarters, in the analysed periods, can be significant – they usually reach several dozen (up to even over 100%), although in nominal terms these differences are usually several or several percentage points. The consumption of biofuels in both countries was higher in the second and third quarters, i.e. in the spring-summer period than others.
