description: In Ethiopia, lentil and chickpea have many of uses as sources of income and in the preparation of various dishes and nutritional security of millions of Ethiopians. Farmers have well recognized the importance of lentil and chickpea as rotation crops in improving soil fertility. However, several biotic agents of viral origin are threatening the production and productivity of chickpea and lentil. The current study was carried out to assess the relative distribution and importance of viruses infecting lentil and chickpea in major production areas to prioritize and design focused and action-oriented research to develop effective management. Two consecutive surveys were carried out in 2018 and 2019 main cropping seasons, and a total of 635 (chickpea, lentil, grasspea and fenugreek) and 676 (lentil and chickpea) samples were collected, respectively, from 57 and 81 fields in central, north, and northwest regions. The study revealed that Pea seed-borne mosaic virus (PSbMV, genus Potyvirus, family Potyviridae) and Chickpea chlorotic stunt virus (CpCSV, genus Polerovirus, family Solemoviridae) are the most-wide spread and frequently recovered viruses from lentil samples, while CpCSV had the highest incidences and was a more prevalent viruse in chickpea fields assessed. Based on this result, integrated management options can be developed targeting factors aggravating the epidemics of the dominant viruses along with continuous disease and vector monitoring.

description: Wild sunflower threatens crop production, animal husbandry, and biodiversity in areas where it has spread. Even though the weed has already concurred huge areas of different land use systems of the Central Rift Valley, there is no available information on its eco-biology. Thus, this study was conducted to generate eco-biological information on wild sunflower by investigating the effects of different seasons of the year, soil ploughing, seed storage time, and burial depth on seed germination and seedling emergence. Wild sunflower matured in about 128 to 141 days, during which it attained a height of up to 82 cm. The weed could produce up to 22 branches and 32 flower heads per plant. The weed attained a biomass yield of about 26 and 34 g plant-1 at Adamitulu and 35 and 44 g plant-1 at Melkassa at flowering and maturity, respectively. Wild sunflower produced 813 to 1124 seeds per plant. Seedling emergence m-2 averaged 42.6 at Melkassa and 34.4 at Adamitulu under unploughed soil but declined to 23.8 and 20.6, respectively, when the plot was ploughed. During the summer, the highest seedling densities of 38.3 and 54.7 plant m-2 emerged at Adamitulu and Melkassa, respectively. The proportion of germinating seeds was highest in seeds stored for 24 weeks (97%), and emergence increased with increasing storage time until germination stabilized while only 2% germinated from freshly harvested seeds. The required storage time for 50% germination was only 2.8 weeks. The percentage of seedling emergence was highest for seeds placed on the soil surface (94%), and decreased with the burial depth; no seedlings emerged from a depth of 6 cm. It was observed that a burial depth of only 2.7 cm reduced seedling emergence by 50%. Overall, the information generated on the biology and ecology of wild sunflower in this study will assist in the development of its management strategies.

description: Urticating ant, also referred to as biting ant, Tetramorium aculeatum Mayr, is an important pest in coffee and becoming a constant problems for the farmers affecting farming activities in Southwestern Ethiopia. Urticating ants are not directly affecting coffee crop, but hindering the agronomic and ripe berry picking activities. As a result ripe coffee beans stay longer in the field and subjected to deterioration. This study assessed the influence of coffee production systems, shade level, and altitudes on the abundance of urticating ant in coffee farms among coffee-producing areas in Southwestern Ethiopia. The study was set as 3x3 factorial and replicated three times considering production system with shade level and again production system with altitude ranges as factors and farms as a replication. Twenty to forty coffee trees were randomly assessed in each farm. The results showed that varying numbers of urticating ant nests were observed on coffee trees among the three coffee production systems, shade coverage level and altitudinal gradients. Production systems in respect to shade levels had a highly significant influence (p < 0.0001) on the abundance of the urticating ant on coffee trees. Coffee trees in plantation production system with heavy shade level had significantly higher mean number of nests per coffee tree (17.25 ± 7.9) compared to the garden and semi-forest coffee in Southwestern Ethiopia. The present study also showed that coffee production system with altitudinal gradient had a highly significant (p = 0.005) effects on the abundance of nests on coffee trees. The urticating ant constructed the highest number of nests (20.10 ± 15.1) on coffee trees in plantation farms under lowland altitudes. Minimum temperature (r = 0.61*) and shade level (r = 0.56*) showed significantly positive correlations to infestation by urticating ant whereas altitude (r = - 0.57*) is negatively correlated with ant abundance. In conclusion, this study revealed population of urticating ant nests varied among coffee production systems, shade levels and altitudinal gradients. In addition, it strongly suggests the abundance of urticating ant is dependent on microclimatic conditions of coffee agro-ecosystems. However, we recommend future study on the ecological role of urticating ant, ecological service or disservice provider to coffee ecosystem, and also this study calls up further studies on the bio-ecology and integrated management methods as it has implication on coffee yield loss.

description: The tomato leaf miner, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) is an introduced serious insect pest of tomato in Ethiopia. Research on the management of this pest has so far been limited to screening of synthetic insecticides. Owing to the pest's ability to develop resistance to insecticides quickly, biological based approach in its management is a viable option. The study was conducted at Melkassa Agricultural Research Center in 2014. The objectives of the study were to assess the efficacy of the microbial insecticide Bacillus thuringiensis (Bt) and the optimum rate and frequency of its application. The tomato variety ‘Miya’ was used for this experiment. The experiment was laid out in a factorial RCBD with three replications. The treatments consisted of four doses of Bt, 0.5, 1, 1.5 and 2kg per ha applied at 7, 14 and 21 days intervals. Lambda cyhalothrin 5% EC (Karate®) and Chlorantraniliprole 240 SC (Coragen ®) at 320 and 250 ml per ha, respectively were applied biweekly as standard checks along with the untreated control. Egg density, leaf damage score, proportion of damaged fruit by number and weight, and marketable yield were used to assess performance of the treatments. Differences for egg density were insignificant (P<0.05) among treatments. Plots treated with the highest rate of Bt (2 kg per ha) at 7 days interval suffered less damage and resulted in higher marketable yield than the rest of the Bt treatments. The lowest fruit damage level of 18.7 % was recorded from Coragen treatment and the highest (81.8%) was recorded from the untreated control. The highest marketable yield of 28.39 tonnes per ha and the lowest of 3.25 tonnes per ha were recorded from Coragen and the lowest Bt rate was applied triweekly, respectively. This corresponds to a yield loss of 88.5%. The study demonstrated the potential of Bt in reducing damage and yield loss due to T. absoluta on tomato when applied with a high dose (2 kg per ha) weekly. It is suggested that future studies need to look into assessing the performance of higher doses and shorter application intervals than considered in this study along with the economics of their use in tomato production.

description: Abstract

This paper presents the complete theory of the Natural Spherical Organization of the Universe, proposing that the universe is a gigantic, spinning, dynamic energy sphere. Based on observations from the atomic to the cosmic scale, the model asserts that spherical structures are the fundamental and natural outcomes of energetic, gravitational, and quantum processes. The universe's nested, hierarchical organization reveals a coherent, living, dynamic, and evolving system that contains within itself a multiverse — a network of nested realities generated by its own dynamic energy fields. This model offers a unified, testable vision of cosmic structure, merging physical laws and evolutionary dynamics into a single living architecture.

description: Stem rust (Puccinia graminis Pers. f. sp. tritici Eriks. and Henn) incurs significant yield losses in wheat in Ethiopia, as most commercial varieties lack sufficient resistance to the rust. New resistance sources identification and incorporation of resistance has continued. Combining adult plant and seedling resistances based Sr-resistance genes is foundation for durable stem rust resistant variety providing effective rust protection. Thirty two durum wheat lines (DW) and 30 bread wheat genotypes (BW) were evaluated for stem rust seedling resistance. Twenty nine DW and 15 BW with heterogeneous seedling infection (2+3-) and > 3- were further evaluated for stem rust adult plant field resistance. Seedling infection types (ITs), host plant responses, terminal disease severity (TDS), coefficient of infection (CI) and relative area under disease progress curve (r-AUDPC) were used for evaluating adult plant resistance. Four DW lines 7974-2, 203680-2, 7974-1, 203831-2 and one advanced BW line ETB9550 expressed low TDS/field response of 15MS-25MS, CI of 12-20 and r-AUDPC of 12-22%. These lines had susceptible seedling infection types and were regarded as highly slow rusting. Likewise, DW lines 5454-1, 6112-1, 203726-2, 203855-2 and 203899-1 and BW lines ETBW9652 and ETBW9313 with >3- ITs showed r-AUDPC, CI and TDS/response of 31-70%, 28-36 and 30S-45MSS, respectively, were grouped to genotypes with moderate slow rusting resistance. Slow rusting resistant wheat genotypes identified from the present study can be used for developing durable stem rust resistant wheat cultivars once they are postulated for their inherent resistance Sr-genes.

description: The tomato leaf miner, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) is a majo insect pest of tomato in the Central Rift Valley (CRV) areas of Ethiopia. Tomato growers complain on the decline in efficacy of the insecticide registered for its control after the detection of the pest in the CRV in 2013. This decline in efficacy of the registered insecticides was hypothesized to be due to insecticide resistance development. Studies were conducted to understand the pesticide use practices against T. absoluta and to assess the occurrence of resistance in T. absoluta population. A survey in two kebeles each of five districts namely Lumme, Bora, Dugda and Adamitulu jido kombolcha of East Shewa zone and Hawassa Zuriya district of Sidama zone was conducted in April, 2017. A total of 44 farmers were interviewed using a structured questionnaire and information was gathered on different aspects of insecticide use. A leaf dip bioassay method was used to assess the occurrence of insecticide resistance using strains of T. absoluta collected from Hawassa, Meki, Awash Melkassa and Ziway areas. Bioassays were performed using insecticides from three classes namely Coragen 200 SC (chlorantraniliprole), Belt 480 SC (flubendiamide) and Radiant 120 SC (spinetoram) in six dilution rates including the recommended rate. Descriptive statistics were used to summarize the survey data. The bioassay data were analyzed using a probit model. Survey results showed that pesticides were generally applied at a higher rate and more frequently than recommended. The level of resistance to the three insecticides was observed to vary with the strains of T. absoluta. The level of resistance for chlorantraniliprole and flubediamide was higher than for Spinetoram. The LC50 values of all strains were far higher than the field rate for all the insecticides tested. Pesticide misuse and abuse were observed to be a common phenomenon in the study area. Higher LC50 values than the recommended field rates and higher resistance ratios suggest that the T. absoluta population in Ethiopia has developed resistance to the insecticides registered for its control. Efforts should be made in developing an Insecticide Resistance Management (IRM) strategy for effective and sustainable resistance management in the chemical control of T. absoluta.

description: Bacterial wilt [Xanthomonas campestris pv. musacearum (Xcm)] is a very destructive disease that attacks enset (Ensete ventricosum). The objective of this study was to characterize Xcm isolates morphologically, biochemically, physiologically and pathogenically. The objective of this study was to determine the morphological, biochemical, physiological and pathogenic characteristics of Xcm isolates collected from Southwestern Ethiopia. One hundred and twenty Xcm isolates were collected from 120 infected enset fields in 10 major enset growing districts, namely Andiracha, Bita, Chena, Decha, Gimbo, Maji, Masha, Semen-Bench, She-Bench and Yeki, in southwestern Ethiopia during 12 June to 08 August 2017, and were isolated on yeast peptone sucrose agar (YPSA) medium in the laboratory. From each sample, a loopful of the suspension was streaked on yeast peptone sucrose agar (YPSA) medium. The plates were arranged in complete randomized design and incubated at 28 °C for 48-72 hours. The isolates were characterized on the bases of their colony growth, morphological, physiological and pathogenic features, and their responses to various biochemical tests. Morphologically, variability among isolates was observed in appearances in colony color that varied from light to deep yellow, and growth as its’ growth type that ranged from low to highly mucoid colony. Moreover, variability in tolerance abilities within isolates was observed under different NaCl concentrations (0-5%) and temperature variation (26, 28, 30 and 32 °C). On the contrary, all the 14 biochemical tests showed similarities amongst the isolates. Thus, potassium hydroxide solubility test revealed that all the isolates were Gram- negative. All the isolates were catalase and oxidase positive, could hydrolyze casein and gelatin, produce H2S, and utilized citrate and malate while the isolates could not reduce nitrate to nitrite, could not hydrolyze Tween 80 (about 92.5% of the isolates) and starch, and could not produce indole. Morphological and biochemical tests in combination with the pathogenicity test confirmed the isolates were Xcm, and suggested the presence of population diversity among Xcm isolates tested. However, further studies that target the genetic diversity of the pathogen using large number of isolates are essential to draw a meaningful inference.

description: Thread blight is one of the fungal pathogens that cause severe damage to Coffea arabica in Southwest Ethiopia. However, there are very few research findings on its management in Ethiopia. Therefore, the current work was designed with the objective to evaluate Coffea arabica genotypes for their reaction to the disease. For this purpose, a field experiment was conducted to evaluate the resistance of 126 C. arabica genotypes against the disease at Mettu, Ethiopia. The experiment was arranged in 8 x8 simple lattice designs with two replications. Out of 126 C. arabica genotypes tested, 14 ( 1 1 %) of them showed highly resistant reaction, while 28 genotypes (2 2 %) were moderately resistant. Additionally, 26, 29 and 12% of the genotypes were moderately susceptible, susceptible and highly susceptible to C. koleroga, respectively. The current study demonstrates the role of host resistance to manage the disease, and it could be considered as potential component in integrated management of the disease. Future research should be directed towards studying the resistance mechanisms of the accessions for possible resistance gene transfer to released coffee varieties.

description: This study evaluated twenty maize varieties for tlieir resistance to Sitotroga cerealella under both free and no-choice tests. Ear damage score, developmental period, total progeny emerged, susceptibility index, percent grain damage and grain weight loss were evaluated susceptibility parameters. Ear husk and grain biophysical characteristics which may influence infestation by S. cerealella were also investigated and correlated with susceptibility parameters. Majority of die varieties were resistant and moderately resistant under free choice test. However, under no-choice test, only three varieties, i.e., Pratap Makka-5, EH-2101 andEH-2253 were categorized as resistant and moderately resistant, while the remaining varieties showed susceptible to highly susceptible reaction. Under both free and no-choice tests Pratap Makka-5, EH-2101 and EH-2253 were grouped under the same category. We found an inverse relationship between husk extension and ear damage (-0.610*), husk leaf number and ear damage (-0.785**), and percent grain damage and grain hardness (-0.648**); while strong positive relationship between grain size and susceptibility index (r=0.673**) and ear damage score and grain texture (r = 0.698**) were observed. Additionally, a strong negative correlation was found between progeny emerged and grain hardness (-0.696**). Our study leads to the conclusion that of the different husk cover and grain physical variables used to assess S. cerealella behaviour and biology; husk extension, husk tightness, grain hardness, grain size, and grain texture were better indicators of resistance for practical application. Such information could be used to establish a baseline for developing agronomically and biophysically elite maize gennplasm that confers resistance against S. cerealella in the field and storage.

description: Fusarium species are the most toxigenic fungal pathogens responsible for various diseases in maize and other food grains. Fusarium infection in maize contaminates harvested grain with mycotoxins such as Fumonisins. Fumonisins contamination in maize can cause yield loss and health problems in humans and animals. The study aims to assess Fusarium species and fumonisin contamination in fresh harvested and three-month stored maize samples collected from five major maize growing districts of eastern Ethiopia, during the 2017/18 cropping season. Fusarium species were isolated and identified using direct plating technique, while Fumonisin concentration was analyzed by ELISA protocols. Higher numbers of Fusarium isolates were recorded in fresh harvested (2376 isolates) than in three-month stored maize samples (1897 isolates). The isolates were recorded in 97 and 90% of fresh harvested and three-month stored maize samples, with an average kernel contamination of 62 and 50%, respectively. A total of seven Fusarium species were identified from the samples. The most prevalent species was F. verticillioides in both samples, followed by F. proliferation and F. subgulitnans in fresh harvested and three-month stored samples, respectively. All fresh harvested and 92% of three-month stored maize samples were found fumonisin-positive (ranging from 105 to 5,460 )ig kg '). In all districts fumonisin concentration recorded in fresh harvested samples (2,509 j.ig kg-1) was higher than that of three-month stored maize samples (1,668 Hg kg-1). Prevalence of different Fusarium species could indicate the possibility of maize contamination by other mycotoxins. Therefore, further studies are needed considering different factors over different cropping years. Findings of the study could serve as foundation for any other study on Fusarium species and fumonisin contamination in maize in Ethiopia to design appropriate management strategies.

description: An electoral system is a device for translating the votes won by candidates in elections into an authoritative outcome, such as seats in a Parliament. Free, fair and frequent elections are essential conditions for any functioning democracy. Determining the best way of translating votes into an election outcome is an exercise fraught with difficulty. Notwithstanding widespread agreement that elections should be free, fair and frequent, there can be disagreement over what fairness means and over other fundamental goals. Should, for example, the prime consideration in an electoral system be achieving an outcome that mirrors the opinion of voters? Or is putting into place a stable and 'strong' government of greater importance?

description: Entomopathogenic nematodes (EPNs) are simple roundworms that naturally kill insects and are abundantly present in the soil. A survey of EPNs was conducted in selected agroecologies of eastern and western Ethiopia with termite problems aiming to assess the species’ diversity and distribution. From a total of 80 soil samples collected, 20% of them were positive for EPNs. They were found in all of the habitats where the study was conducted, but they were more abundant in soil samples collected from tree litters than in any others. Molecular analysis of the recovered EPNs of the internal transcribed spacer ITS region and D2\D3 expansion segments of the 28SrRNA gene were conducted. The results of the molecular analysis revealed the presence of three types of PNs viz., Oscheius tipulae, Heterorhabditis indica and Caenorhabditis briggsae. Among the recovered nematodes, Oscheius spp. are obtained from eight, II. indica from six, and C. briggsae from two soil samples. Oscheius spp. belong to the gronp of insectivores whereas Heterorhabditis belongs to the obligate parasite group of nematodes. All the three species recorded in the study were reported for the first time from Ethiopia. Further surveys should be conducted in the future to ensure the untouched sites of the country.

coffee productions in Ethiopia. The current study assessed the status of antestia bugs in 12
districts of the Oromia and Southern Nations, Nationalities and People’s Regions (SNNPR) in
the southwestern Ethiopia in 2017/2018 cropping year. The sample sizes were thirty coffee trees
per farmer, five farmers per Farmers’ Association and three Farmers Associations in each
district. The antestia bugs were counted in each tree and hundred ripe berries were sampled from
each tree and sorted to beans with darkening and clean beans. Three stage nested designs and
correlation analyses were used for data analyses. Infestations were higher at districts o f Ale (0.87
bugs/tree), Shabe Sombo (0.82 bugs/tree) and Mettu (0.41 bugs/tree), low at Sheko (0.03
bugs/tree), while no record was made at Gurra Farda, Debub Bench. Similarly, the highest
percent number of bean damage was recorded at Ale district (1.20%), followed by Shabe Sombo
(0.86%) and Mettu (0.62%). The study showed that antestia bugs infestation and coffee bean
damage increased with altitude (y = 0.005x - 0.428, r = 0.358), level o f coffee shade. Forest and
plantation coffee production systems had the lowest antestia bug infestations and bean damages,
while garden and semi-forest coffee had the highest. Local coffee varieties had higher antestia
bug infestation and bean damage than the improved varieties, which are usually grown under
better agronomic practices, including shade and canopy management and protection of pests with
pesticides. The population of antestia (0 - 0.87 per tree) in most of the study area was below the
economic threshold level of one to two bugs per tree. Studies are suggested on the seasonal
abundance, effect of microclimate, natural enemies and management practices on the population
dynamics of the pest, and the economics of antestia bugs in the major coffee growing areas of the
country.

description: Weeds reduce the yield and quality of faba bean if they are left unmanaged. Therefore, a field
experiment was conducted using the faba bean variety Gachena (EH91001-13-2) as a test crop
under rain fed conditions at Haramaya, eastern Ethiopia, during 2017 main cropping season with
the objective to determine the critical period of weed competition in faba bean. Twelve
treatments in two sets, i.e. increasing duration of weedy and weed-free set each comprising weed
competition and weed-free durations up to 15, 30, 45, 60 and 75 days after crop emergence
(DAE) up to harvest, were laid out in a randomized complete block design with three
replications. The data were collected on both weeds and the crop. The results of the study
revealed that the maximum faba bean grain yield loss due to weedy check was 55.7% as
compared to the grain yield from weed-free check (3,376 kg h a 1). Thus, to prevent more than 5%
yield loss of faba bean, the variety Gachena should be kept free of weeds from 237 to 669
growing degree Celsius days.

description: Potato tuber moth is an oligophagous pest of different solanaceous crops. The present study evaluated the potential of intercropping tomato with other solanaceous species as trap crops in safeguarding tomatofrom PTM damage. Paired potato, wild solanum, eggplant, tobacco, and tomato were caged open in the field as sole and mixed species and also planted in the open as sole and mixed crops. The paired plants were artificially inoculated with four mated females. The open field grown plants were left for natural infestation. The leaves of the different solanaceous species were inspected once a week for PTM larvae presence and level of parasitism was also determined in the lab. In the cage experiment, unlike for same species paired; there was a significant difference in PTM larva density for each paired species and the lowest larval density was in tomato. Whereas in the open field, the number of recovered larvae on eggplant and tomato was significantly lower than on the other species. In the field cages, Diadegma mollipla (Holmgren) release in the field cage parasitized larvae only on the leaves that were present potato, wild solanum, and eggplant. Similar results were obtained in the open field. Unidentified parasitoid was recorded on tobacco leaves of tobacco in the open field. The results illustrate that presence of potato, tobacco, eggplant or wild solanum present in the proximity of tomatofield would serve as trap plant for PTM and its parasitoids and help reduce damage to tomatoes fruits.

description: Tomato early blight (Alternaria solani) is an important disease of tomato that reduces quantity and quality of fruit yield. Field experiments were conducted in 2016 and 2017 cropping seasons with the objective to evaluate the effect of varieties and fungicide application frequencies on early blight epidemics, total fruit yield and yield components. Treatments included four tomato varieties with different resistance levels and four foliar fungicide spray frequencies alone and in combination, including unsprayed plots as control. The treatments were arranged factorially in a randomized complete block design (RCBD) with three replications. The integrated use of tomato varieties with fungicide spray frequencies significantly reduced early blight epidemics and increased fruit yield parameters. A minimum mean disease severity was calculated for tomato varieties evaluated in the order of ART tomato d2, Roma VF, Bisholla and Melkasholla at 61 days after planting in four times fungicide sprayed plots compared to unsprayed plots in 2016 cropping season. A similar trend was observed in 2017 cropping season. The highest (12.54- 17.79%-days) rAUDPC values were calculated for unsprayed plots in 2016 and 15.71-22.16%- days during 2017 cropping season. Roma VF produced the highest (49.15 t h a '1) and Melkasholla gave the lowest (18.71 t ha ') mean marketable fruit yields, with three times fungicide spray frequencies in both cropping seasons. The study indicated that the inherent genetic potential of tomato varieties is complemented by foliar application of ridomil fungicide that contributed to low blight epidemics and high fruit yield, and provided higher net benefit with optimum marginal rate of return. It is commendable to screen additional tomato varieties and fungicides to come up with reliable recommendation against early blight for sustainable tomato production in the study area and other locations with similar agro-ecologies.

description: Although nitrogen-containing heterocycles and sulfonamides both play crucial roles in the chemical and pharmaceutical industries, surprisingly little research exists that examines the bifunctional N-(2-(pyridin-2-yl)ethyl)sulfonamide scaffold for any potential applications. Retrosynthetic analysis indicates that this skeleton would be well suited for a conjugate addition reaction. However, the ability of 2-vinylpyridine to behave as an acceptor, and of sulfonamides to behave as donors, has very limited literature precedent, and thus required some preliminary investigations into their mutual reactivity. Herein outlines our laboratory's discovery of a novel and efficient solvent-free 1,4-aza-conjugate addition reaction between sulfonamides and 2-vinylpyridines that provides expedient access to various N-(2-(pyridin-2-yl)ethyl)sulfonamide derivatives. The products, possessing multiple sites of Brønsted acidity and basicity in close proximity, could display a wide array of valuable host–guest properties and should thus be investigated for potent pharmaceutical or agrochemical properties.

description: Mobile display devices such as phones and PDAs have become very widely available and used. However, most content on these devices is limited to text, static images and motion video. Displaying and interacting with dynamic diagrammatic content on such devices is difficult, as is engineering applications to implement such functionality. We describe a set of plug-in components for a meta-diagramming tool that enable a diagram type to be visualized and interacted with on mobile devices. Key features of our approach include generating diagram content from an existing meta-tool, run-time user configuration of diagram appearance and navigation, and multi-level, zoomable diagrams and diagram content. We describe our experiences prototyping, using and evaluating this new mobile device diagramming technology.
