Integration of Heat Pump Storage Systems in Manufacturing Systems via Data Farming and Monte Carlo Simulation
(2019)
The electrification of industrial energy demand is essential for effective climate protection and a successful energy transition. In production systems with fluctuating heating and cooling demands, heat pumps can make a significant contribution to electrification and increased efficiency in a demand-oriented production with automated standby operation. In order to dimension a suitable heat pump storage system, well-founded statistical information about the production system is required. For the creation of stochastic ...

Constraints to commercialisation of smallholder agriculture in Tanintharyi division, Myanmar
(2019-12-17)
Myanmar is a country in rapid economic and political transition, with opportunities emerging for its smallholders to benefit from current economic growth. However many smallholders are trapped in semi-subsistence agriculture, disconnected from markets. Commercialisation can increase farm incomes, and - through the multiplier effect - lead to wider pro-poor growth in the rural economy. However, there are many constraints to commercialisation that prevent this process from occurring. While literature on constraints ...

Responses of Filipino farmers to harsh weather phenomena: A risk perception and attitude study
(2019-12-17)
Small-scale farmers, whose livelihood and food security greatly depends on farming, are constantly exposed and vulnerable to the risks of extreme weather events. The current study explored how the perception and attitude on agricultural risks of small-scale farmers from the upland, lowland and waterside ecosystems in Siniloan, Laguna in Philippines influence the way they respond and cope with extreme weather events. The study employed quantitative and qualitative data collection methods particularly farm surveys, ...

Assessment of varietal diversity and production systems of cowpea (Vigna unguiculata (L.) Walp.) in Southwest Nigeria
(Kassel University Press, 2019-01-11)
Cowpea (Vigna unguiculata (L.) Walp.) is the most important source of plant protein consumed in Nigeria with major supplies coming from the northern part of the country. However, reduction in supplies due to insurgency resulted in sharp increases in price, especially in Southwest Nigeria where cowpea is relished in different delicacies. Sustainable production increase in suitable Southwest agro-ecologies depends on suitability of cultivated varieties and production practices of the farmers. A study was conducted to ...

Construction and Use of a Simple Index of Urbanisation in the Rural–Urban Interface of Bangalore, India
(2017-11-21)
Urbanisation is a global trend rapidly transforming the biophysical and socioeconomic structures of metropolitan areas. To better understand (and perhaps control) these processes, more interdisciplinary research must be dedicated to the rural–urban interface. This also calls for a common reference system describing intermediate stages along a rural–urban gradient. The present paper constructs a simple index of urbanisation for villages in the Greater Bangalore Area, using GIS analysis of satellite images, and combining ...

Effect of Sowing Method and Weed Control on the Performance of Maize (Zea mays L.) Intercropped with Climbing Beans (Phaseolus vulgaris L.)
(2017-06-23)
Maize is grown on a large area in Germany and there is a growing concern in society about negative environmental effects related to this. The objective of the study was to test the performance of mixtures of maize and climbing beans as an alternative to monocropped maize under different site and management conditions. The effects of sowing density of maize and beans as well as the sowing time of beans on total dry matter (DM) yield and bean DM contribution to the total yield were investigated. Further, various ...

Nutritional Comparison of White and Red Coccinia Abyssinica (Lam.) Cong. Accessions: An Under-Utilised Edible Tuber of the Ethiopian Highlands
(2017-08-22)
Anchote (Coccinia abyssinica) is an indigenous tuber crop of the Ethiopian Highlands. It is popular in the western Oromia Region of the country. Apart from food, the crop is also used in traditional medicine. Anchote tubers possess two variations in its tissue colour, red and white. In this study, a small market survey and a nutritional comparison of red and white anchote were conducted. White tissue anchote seems to be more popular, due to its soft texture and ease of cooking. However, the red variant was considered ...

Preparation and Molecular Structure of a Cyclopentyl-Substituted Cage Hexasilsesquioxane T6 (T = cyclopentyl-SiO1.5) Starting from the Corresponding Silanetriol
(2017-10-04)
Cyclopentyl substituted silanetriol can be prepared and isolated. Its condensation yields the corresponding disiloxanetetrol as a primary condensation product. Further condensation leads to the hexameric polyhedral silsesquioxane cage T6. The latter has been mentioned in the literature before however, lacking structural data. All compounds have been characterized with multinuclear NMR spectroscopy and, in addition, the molecular structures have been determined in the case of the disiloxanetetrol and the hexasilsesquioxane ...

Climate-smart agriculture policy and (in)justice for smallholders in developing countries
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2019-06-05)
The Food and Agriculture Organization of the United Nations developed the term Climate-Smart Agriculture as an approach to transform agricultural systems to support development and ensure food security in a changing climate. This paper analyses whether climate-smart agriculture policy meets the demands of climate justice and respects the rights of smallholders; and if not, how it could be amended. The study is based on a literature review supplemented by four interviews with climate-smart agriculture actors from ...

Metallated [3]Ferrocenophanes Containing P3M Bridges (M = Li, Na, K)
(2018-07-11)
Alkali-metal phosphanides can be embedded into a [3]ferrocenophane scaffold giving rise to bicyclic ferrocenophanes [MFe(C5H4PtBu)2P] (M = Li, Na, K). Coordination of the alkali-metal ions takes place via the terminal phosphorus atoms adopting a puckered P3M four-membered ring. All compounds were characterized via single-crystal X-ray diffraction and multinuclear NMR spectroscopy (1H, 31P, 7Li), whereas 13C NMR data could only be recorded for the Li derivative, owing to the limited solubility of its heavier congeners ...
