Optimal Control of Quantum Information Tasks in Open Quantum Systems
(2020-07-30)
Every quantum system inevitably interacts with its environment. This is a fundamental requirement that allows us to control, measure and, in general, interact with quantum systems. In that respect, a quantum system's openness can be interpreted as prerequisite that enables quantum technologies in the first place. The latter are built to harness the intrinsic quantum mechanical behavior of quantum devices in order to build new, powerful technologies. However, a quantum system's openness also causes it to interact ...

Factors driving adoption and constraining the non-adoption of biofortified orange fleshed sweet potatoes (OFSP) among farmers in Abia State, Nigeria
(2020-09-22)
This study sought to determine the factors that drive the adoption and constrain the non-adoption of Orange Fleshed Sweet Potato (OFSP) varieties among farmers in Abia State, Nigeria. Multistage sampling procedure was used in selecting sixty sweet potato farmers (thirty adopters and non-adopters each). Participatory tools such as structured interview schedule, key informant interviews and personal observation were employed for quantitative and qualitative data collection. The data were analysed using descriptive ...

Volatile Compounds effects in Industrial Food Recipes using Food Pairing Method
(2020-12)
The present study aims to investigate the flavour pairing-methodology for product development in an international acting company. Besides the sensory tests, analytical investigations and algorithmic works are part of the research.
In this study, original food ingredients (eighty-seven flavouring ingredients) which are mostly consumed in Turkey and some of them are currently used in a worldwide acting company (Headquarter in Germany with a branch in Turkey) were examined to postulate which ingredients should be brought ...

Effects of agroecological practices on soil organic carbon sequestration using synchronic and diachronic approaches in Madagascar
(2020-06-16)
Soil organic carbon (SOC) sequestration in agricultural systems is a key indicator of soil fertility improvement and climate change mitigation at the global scale. In Madagascar, the effect on SOC sequestration of converting from traditional practices to agroecological ones remains unclear. The objectives of this study were (i) to assess the impact of agroecological practices, such as agroforestry (AF), tree plantation (TP) and improved farming practices (IFPs), on SOC sequestration at the field level; and (ii) to ...

Morphology, biochemistry, and management of Russian olive (Elaeagnus angustifolia L.) accessions in Gilgit-Baltistan, northern Pakistan
(2020-07-30)
Russian olive (Elaeagnus angustifolia L., Elagnaceae) is a native multi-purpose medicinal shrub or tree of Asian regions and an integral component of high altitude terraced agroforestry systems of Gilgit-Baltistan, northern Pakistan. The strong increase in deforestation, urbanisation, and the loss of ethnically-based medication practices in local communities are gradually leading to depletion of its stands and knowledge of its use. In view of these circumstances, this study was undertaken to characterise Russian olive ...

Variation in baobab (Adansonia digitata L.) root tuber development and leaf number among different growth conditions for five provenances in Malawi
(2020-08-21)
The baobab tree is an underutilised indigenous fruit tree in sub-Saharan Africa which, at the same time is vulnerable to overexploitation in areas close to centres of demand, as currently baobab use is limited to wild, baobab trees. Baobab seedlings are known to form root tubers, but little is known about their growth characteristics and its yield potential. This study aims to investigate the root tuber and leaf development of baobab seedlings grown from seeds of five provenances, sown at three different planting ...

Development of Carrier-Envelope-Phase-Stabilized, mJ-Class Laser Sources Generating Intense, Few-Cycle Laser Pulses
(2020-05-19)
Over a decade ago the frontiers of ultrashort physics and nonlinear optics have reached the attosecond timescale ($1 as = 10 ^ {-18} s$) . Currently, in order to generate isolated attosecond pulses, an intense femtosecond pulse is focused in a jet of a noble gas. Given the sufficient intensity, this leads to high harmonic generation (HHG), which can be filtered (gated) to create a single isolated attosecond pulse. The laser source for the driver pulses has to fulfill two requirements: the pulses need to be limited ...
