Genotypic differences in body weight and physiological response of local and exotic turkeys challenged with Salmonella typhimurium
(2021-11-02)
To better understand susceptibility and/ or tolerance of locally adapted turkey to salmonellosis, we compared bodyweight, antibody titres and physiological traits based on genotype and sex of salmonella-infected turkeys. Three hundred poults from two genotypes (160 local and 140 exotic turkeys) were raised for twenty weeks. Bodyweight (BW), rectal temperature (RT), pulse rate (PR) and respiratory rate (RR) were measured weekly. Blood samples were collected from each turkey before and after inoculations at week 8 and ...

The effect of physical activity on motor cognition in elderly people
(2021-12)
For the presented doctoral thesis, four cross-sectional studies and a longitudinal study were conducted to examine the correspondence between physical activity and motor cognition in older adults. A total of six hypotheses were tested. Forty older adults between 65 and 80 years of age (subdivided into an active and an inactive subgroup based on Freiburg Physical Activity Questionnaire) and 20 sports students as a control group participated in the cross-sectional studies. Eighty-two seniors aged between 65 and 80 years ...

Agricultural risk assessment to enhance the food systems of the Mbororo minority community in the Northwest region of Cameroon
(2021-10-29)
Increasing population pressure, coupled with the effects of climate change manifested by longer dry seasons, wildfires, and conflicts, threatens the food systems of minority communities. In the case of the Mbororo minority community of Northwest Region of Cameroon, these threats are exacerbated by already existing problems of marginalisation. This study assesses agricultural risks in the global context of food distribution and gross domestic product that also poses a specific threat to the food system of the Mbororo ...

Preliminary assesment on drought tolerant oil palm in semi-arid area
(2021-12-15)
The evaluation of oil palm growth performance and their corresponding effect on drought very crucial in selection of proper parent’s tree. The parent palm that showed drought tolerance and have less effect on oil yield is important for optimisation semi-arid lands usage in future. The Split plot with two replications in a randomized complete block design (RCBD) were conducted and mixed stand with an adjacent control plot. All 19 progenies was evaluated and interaction effects are estimated using split plots analysis. ...

Formal Verification for ALICA Plans
(2021)
Mit der Entwicklung von Wissenschaft und Technik steigen auch die Fähigkeiten autonomer Roboter. Immer mehr und kompliziertere Roboterszenarien werden in vielen Bereichen realisierbar, wie z. B. Mäh-, Ernte- und Lagerroboter. Daher wird die Planung für sie zu einer immer wichtigeren Aufgabe. Da diese Roboter jedoch täglich komplexer werden, ist die Sicherheitszertifizierung ein unvermeidliches Anliegen bei der Entwicklung von mehr autonomen Robotern. Daher ist die Verifizierung der Pläne vor der Verwendung und dem ...

Three-dimensional hydrodynamic and ecosystem modeling of warm-monomictic reservoirs (Maroon and Abolabbas, Iran) under the impact of 21st century climate change
(2021-11)
Lakes and reservoirs, as the endpoint of their upstream catchment, collect their water as the resultant of the hydrological and ecosystem processes and, thus, act as a gauge of their catchment’s management. Physical processes, e.g. stratification and mixing and propagation of density currents, are the main drivers of the biochemical factors in lakes and reservoirs and are prone to be altered and affected by climate change. Hydrodynamic models are the tools to simulate the behavior of the water body under various ...

Antioxidant activity of a mixture of water-soluble tempeh extract with whey powder that has undergone a Maillard reaction
(2021-12-20)
High amino acid content in tempeh and lactose in whey powder can be combined to perform Maillard reaction. So, it can be used to produce functional food products. This is caused by the formation of Amadori and melanoidin as water-soluble compounds which are reported to have high antioxidant capacity and produce a preferred flavor. The general objective of the study was to obtain an optimum process condition in a mixture of water soluble tempeh extract and whey powder with the highest antioxidant capacity (100 mL). ...

Rainfall erosivity, soil erodibility and natural water erosion potential in the Huambo region, Angola
(2021-12-06)
The use of erosion assessment methods is critical for the sustainability of land use in tropical and subtropical regions, especially in countries lacking national information on soil erosion development, which is the case of Angola. This study aimed to evaluate the rainfall erosivity (R), soil erodibility (K), soil loss tolerance (T) and natural erosion potential (NEP) in Huambo (Angola). The R value estimated for a 25-year period was 7463 MJ·mm·ha-¹·h-¹·y-¹. K values estimated from 25 soil profiles, described in the ...
