Authors: Dalm, M.; Advisor: -; Participants: Buxton, M. W. N.; Van Ruitenbeek, F. J. A. (2019) - The results showed that NIR-SWIR hyperspectral imagery could be used to segment a population of waste samples by detecting occurrences of pyrophyllite, dickite and/or illite. This result can be explained by the fact that these minerals are commonly deposited further away from the ore-bearing epithermal veins, while the
absence of SWIR-active minerals or detected occurrences of alunite are more closely associated with these structures. The ability to identify waste with NIR-SWIR spectral sensors means there is potential that sensor-based sorting can be used to remove this waste from mineral processing operations. Additional research is still required to assess the economic feasibility of such a sensor-based sorting application.

Authors: Dawood, M.G.; Advisor: -; Participants: Abdel-Baky, Y.R.; El-Sayed El-Awadi, M.; Bakhoum, G.S. (2019) - Data show that nicotinamide at 5, 10, and 20 mg/L and/or humic acid at 5% had a positive effect on growth parameters, photosynthetic pigments, seed yield, and yield components as well as some biochemical constituents of the yielded faba bean seeds (total carbohydrate, total phenolic content, proline, and free amino acids). Individually, nicotinamide treatments had a more positive effect than humic acid treatment and their effect was increased by increasing nicotinamide concentrations. The most promising treatment appeared due to the interaction between nicotinamide at 10 mg/L and humic acid. Hence, this treatment increased plant dry weight/plant by 32.67%, total photosynthetic pigments by 113.2%, seed yield/feddan by 110.16%, total carbohydrate by 9.4%, total phenolic content by 0.3...

Authors: Moustafa, K.G.; Advisor: -; Participants: Saied, G.M. (2019) - Except for case 4, all patients were females. The symptoms and clinical findings in the six cases were vague and did not raise the possibility of a carcinoid. Repeated local recurrence was the clue for the diagnosis. The enrolled six cases had no common features that may point or suggest the presence of neither carcinoid tumor nor syndrome. Also, there was no relation between the site and size of the tumor and the detection of the manifestations of carcinoid syndrome. Additionally, in one case (case 1), the originally non-functioning lesion turned active when recurrence happened.

Authors: Ranguelova, E.; Advisor: -; Participants: Weel, B.; Roy, D.; Kuffer, M.; Pfeffer, K.; Lees, M. (2019) - Slums, characterized by sub-standard housing conditions, are a common in fast growing Asian cities. However, reliable and up-to-date information on their locations and development dynamics is scarce. Despite numerous studies, the task of delineating slum areas remains a challenge and no general agreement exists about the most suitable method for detecting or assessing detection performance. In this paper, standard computer vision methods – Bag of Visual Words framework and Speeded-Up Robust Features have been applied for image-based classification of slum and non-slum areas in Kalyan and Bangalore, India, using very high resolution RGB images. To delineate slum areas, image segmentation is performed as pixel-level classification for three classes: Slums, Built-up and Non-Built-up. F...

Authors: Uwiringiyimana, V.; Advisor: -; Participants: Ocké, M. C.; Amer, S.; Veldkamp, A. (2019) - There was a 42% stunting prevalence. Prevalence of continued breastfeeding and exclusive breastfeeding were 92% and 50%, respectively. Most children (62%) fell into the low dietary diversity score group. The nutrient intake from complementary foods was below recommendations. The odds of stunting were higher in children >12 mo of age (odds ratio [OR], 1.18; 95% confidence interval [CI], 1.08–1.29). Exclusive breastfeeding (OR, 0.22; 95% CI, 0.10–0.48) and deworming tablet use in the previous 6 mo (OR, 0.25; 95% CI, 0.07–0.80) decreased significantly the odds of stunting in children. Also, the body mass index of the caretaker (β = 0.08 kg/m2; 95% CI, 0.00–0.17) and dietary zinc intake (β = 1.89 mg/d; 95% CI, 0.29–3.49) were positively associated with the height-for-age z scores.

Authors: Niamir, A.; Advisor: -; Participants: Skidmore, A. K.; Muñoz, A.; Toxopeus, A. G.; Real, R. (2019) - We invited experts to fill in an online questionnaire and express their beliefs on the habitat of the species by assigning probability values for given environmental variables, along with their confidence in expressing the beliefs. We then calculated evidential functions, and combined them using Dempster’s rules of combination to map the species distribution based on the experts’ knowledge. We evaluated the performances of our proposed approach using the atlas of Spanish breeding birds as an independent test dataset, and further compared the results with the outcome of an ensemble of conventional SDMs. Purely based on expert knowledge, the DST approach yielded similar results as the data driven SDMs ensemble. Our proposed approach offers a strong and practical alternative for specie...

Authors: Abd-Elgawad, M.M.M.; Advisor: -; Participants: - (2019) - The nematode losses vary according to nematode species, population density, and biotic and abiotic factors. Interaction of nematodes with soil-borne fungi increases the severity of disease, and their synergistic effect may result in much higher losses. Therefore, important PPNs on strawberry in Egypt and issues relevant to strawberry yield losses are presented herein. Meloidogyne spp. are the most predominant species on strawberry plants in Egypt. Integration of different methods such as cultural, chemical use of resistant cultivars and naturally occurring biological control agents suggested herein can play a significant role in sustainable nematode pest management of strawberry. For nurseries, there is an urgent need to motivate private and governmental sectors to satisfy the requi...

Authors: Vargas, L.; Advisor: -; Participants: Willemen, L.; Hein, L. (2019) - In this study, we examined how net primary productivity derived from remote sensing can be used as an indicator to assess changes in the capacity of ecosystems to supply services. We examine the spatial and temporal
patterns in this capacity for the Orinoco river basin from 2001 to 2014. Specifically, we analyze the capacity of six types of ecosystems to supply timber, pastures for grazing cattle, oil palm fresh fruit bunches and to sequester carbon. We compared ecosystem capacities with the level of ecosystem service supply to assess a sustainable use of ecosystems. Our study provides insights on how the capacity of ecosystems can be quantified using remote sensing data in the context of ecosystem accounting. Ecosystem capacity indicators indicate ecosystems change and harvesting-...

Authors: Panthi, S.; Advisor: -; Participants: Poudel, S.; Mishra, B. (2019) - The tiger Panthera tigris is distributed in Nepal as well as12 other countries of Asia. It is classed as ‘Endangered’ inthe IUCN red list (GTRP, 2010; Goodrich et al., 2015), isincluded in Appendix I of the Convention on InternationalTrade in Endangered Species (CITES, 2017), and is pro-tected by the Nepal’s National Parks and Wildlife Conserva-tion Act (GoN, 1973). The Global Tiger Recovery Programwas introduced in 2010 to double the tiger population by2022 (GTRP, 2010). As a tiger range country, Nepal isworking hard to increase the number of Bengal tigers, froma national population of 155 in 2010 to double by 2022(DNPWC, 2010; GTRP, 2010); the total number of tigersincreased to 198 in 2013 (DNPWC, 2016).

Authors: Gesraha, M.A.; Advisor: -; Participants: Ebeid, A.R. (2019) - The obtained data revealed that the least number of the prevailing adults was recorded at the treated plot after 2 h post treatment for Coccinella and after 12 h for Stethorus adults. In addition, it could be observed that the mean number of the recorded adults occurred in the untreated plot of the first area was increased significantly than that of the untreated second area at 12 and 48 h and after 1 week post treatment, this could be referred to the following: when the treated plot was sprayed with sulfur compound, most of the prevailing adults escaped from the dust and migrate to the untreated plot or other clean plants (untreated plot or other surrounding plants), then they returned back gradually to the treated plot.
