A pilot investigation of the relationship between climate variability and milk compounds under the bootstrap technique
(2015)
This study analyzes the linear relationship between climate variables and milk components in Iran by applying bootstrapping to include and assess the uncertainty. The climate parameters, Temperature Humidity Index (THI) and Equivalent Temperature Index (ETI) are computed from the NASA-Modern Era Retrospective-Analysis for Research and Applications (NASA-MERRA) reanalysis (2002–2010). Milk data for fat, protein (measured on fresh matter bases), and milk yield are taken from 936,227 milk records for the same period, ...

Comparing apples and pears in studies on magnitude estimations
(2013-06-18)
The present article is concerned with studies on magnitude estimations that strived to uncover the underlying mental representation(s) of magnitudes. We point out a number of methodological differences and shortcomings that make it difficult drawing general conclusions. To solve this problem, we propose a taxonomy by which those studies could be classified, taking into account central methodological aspects of magnitude estimation tasks. Finally, we suggest perspectives for future research on magnitude estimations, ...

Spatio-temporal patterns of herbage availability and livestock movements: A cross-border analysis in the Chinese-Mongolian Altay
(Springer, 2016-07-04)
Due to increasing population and the recent implementation of policies to intensify the use of land and water resources, the transhumant pastoral systems in the Chinese-Mongolian Altay-Dzungarian region are rapidly changing, leading to modifications of herd size, herd composition and spatial distribution of livestock grazing. This may have major consequences for the supply and quality of rangeland biomass. Despite similar topographic settings, the socio-political framework for Chinese and Mongolian pastoralists differs ...

Understanding the emergence and evolution of pastoral community groups from the perspective of community members and external development actors in northern Kenya
(Kassel University Press, 2019-01-15)
Whereas there is abundance of information on community groups that engage in income generation in rural agricultural and peri-urban areas, information on community groups in pastoral areas still remains scarce. However, in the recent past, a growing trend of such groups has been observed in the pastoral areas in northern Kenya. This study therefore explores how these groups have emerged since Kenya’s independence in 1963 to date, and which factors have contributed to their evolution. A full survey on all income-generating ...

An Exploration on Factors Influencing Certified and Farm-Saved Seed Use: A Case Study in Turkish Wheat Farming
(2020-11-29)
Seeds are an important input for wheat-growing, as is the case for all crop production. The type and quality of seed in crop production are the first condition for productivity and accordingly certified wheat seed use is being encouraged by the government since 2005 in Turkey. This study examined the factors affecting the certified seed and farmer (farm)-saved seed use in wheat farming in Turkey. The result of the analyses showed that there is a significant difference between farmers using certified seed and farm-saved ...

Lesson learnt from Smart Rice Actions in Indonesia
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2018-12-26)
Smart Rice (SR) actions are innovative farming practices derived from climate smart agriculture (CSA) concepts and are directed to comply with mitigation and adaptation strategies to climate change. This study provided information about the plausible implementation of SR actions in Indonesia based on literature reviews and stakeholders’ consultation with key informants work- ing on crop management and climate information. The SR actions recommendations are a set of farming practices applied to fulfill the needs of ...

Optimal Energy Supply Structures for Industrial Sites in Different Countries Considering Energy Transitions: A Cheese Factory Case Study
(2016)
This present study focuses on analysing the most efficient utility energy supply structure in terms of primary energy efficiency, carbon emissions and energy costs. In the German dairy industry, separate conversion with gas fired steam boiler, and cooling with ammonia chillers are the-state-of-the-art technologies. It is attractive due to its robustness and low investment costs. But given the ongoing energy transition to renewable energy, opportunities to reduce emissions will become increasingly important. There are ...

Das ‚effiziente Museum‘ im Widerstand gegen die ‚Diktatur der Wand‘
(2020-05-12)
Der vorliegende Beitrag geht von der Annahme aus, dass es sich bei der innovativen Ausstellungspraxis der Nachkriegszeit um eine ‚zweite Museumsreform‘ handelt, einen theoretischen Neuansatz, der die gegenüber der Vorkriegszeit abweichende Ausstellungspraxis der Epoche erst verständlich werden lässt. Zur Überprüfung dieser These liegt der folgenden Studie eine systematische Erfassung von museumstheoretischen Stellungnahmen in den Kulturzeitschriften der Nachkriegszeit in mehreren westeuropäischen Ländern zugrunde, ...

Dimensioning of Heat Pump Systems Based on Pinch Analysis and Energy Monitoring Data
(2018)
In this paper, typical process chains of metal processing/gear manufacturing are examined according to the pinch method with regard to their potential for heat recovery and their suitability for heat pump applications. The focus is on machine tools and parts washing machines as fluctuating heat sources and sinks. Heat sources at a low temperature level, such as the cooling of machine tools, are becoming increasingly important in contrast to conventional fossil waste heat sources due to the electrification of energy ...
