No full textSynthesis of some Novel 2-Pyrazolyl-4(3h)-Quinazolinone Derivatives with Potential Antimalarial and Antileishmanial Activities
No full textIn this work, some derivatives of 2-pyrazolyl-4(3H)-quinazolinones have been synthesized by
cyclization and condensation reactions. The synthesized compounds were obtained in a good
yield (55.9-94%). The chemical structures of the final compounds were also verified by
spectroscopic tools (IR, 1H NMR and elemental microanalyses). The in vivo anti-malarial
activity of these compounds against P.berghei infected mice was found to be moderate at oral
dose of 48.46 μmol/kg/day. This dose is equivalent to 25 mg/kg of chloroquine phosphate which
causes 100% inhibition of the parasite. Among the synthesized compounds, 2-(3-(thiophen-2-yl)-
4,5-dihydro-1H-pyrazol-5-yl)-3-phenylquinazolin-4(3H)-one, Xa, showed better activity with
percent suppression of 65.89. The synthesized compounds were also evaluated for their in vitro
anti-leishmanial activity against L. donovani. Among the synthesized compounds, compound
IXe (IC50=0.0121 μg/ml) was found to possess four fold the potency of amphotericine B
(IC50=0.0460 μg/ml) while it was two hundred sixty four (264) times more potent than
miltefosine (IC50=3.1911 μg/ml). Compound Xa (IC50=0.0211 μg/ml) was twice more potent
than amphotericine B and this is the second most active compound as anti-leishmanial agent
among the synthesized compounds. The synthesized compounds exhibited better inhibitory
activity as indicated by their lower IC50 than miltefosine, except for compound XI. Compound
XI showed the least activity which might be due to the presence of a phenyl group on the
pyrazole N1. Furthermore, in the thiophen series cyclization of α,β-unsaturated compounds to the
corresponding pyrazoline analogs led to improvement in activity while the phenyl series showed
conflicting results
Diversification of wheat based cropping system through the introduction of high yielding barley and durum wheat in the highlands of Ethiopia
No full textAbout 4.1 million farmers grow wheat in Ethiopia. Area coverage is 1.7 million ha. Wheat productivity is low due to diseases (rusts), grassy weeds and poor soil fertility, which is happening due to mono-cropping. Diversification of bread wheat production with high yielding and disease resistant durum wheat and barley is critical to improve food security and income of smallholder farmers
Breaking wheat-based monocropping system through scaling of diverse crops and varieties in the highlands of Ethiopia
No full textBread wheat is the third important food crop in the highlands of Ethiopia. Monocropping and rust disease epidemics remain challenges to increase bread wheat productivity and production. One of the strategies used in the AFRICA RISING (2012-2022) project was re-introducing high-yielding food and malt barley, durum wheat, and food legumes into the bread wheat-based cropping system through participatory variety selection (Phase I) and, community seed production and scaling (Phase-II
Annotating Significant Relations on Multimedia Web Documents
No full textAnnotation is a fundamental activity for information extraction. Annotation of large
corpora provides a basis for building ontologies and thesauri (Braschler and Schauble
2000), while annotation of existing data helps adding semantics (Volz et al. 2004).
The elements to be annotated range from simple text (Kahan and Koivunen 2001),
to structured data (Geerts et al. 2006), images (Herve and Boujemaa 2007), and
video (Del Bimbo and Bertini 2007), while the annotation content can be as simple
as a tag (Zheng et al. 2008a,b) or as complex as a whole new document (Bottoni
et al. 2006), most commonly being text. While traditional annotation on paper alter
the physical support of the document, digital annotations can be added at will on a
digital document without modifying it, still maintaining their relationship to the
original document through suitable metadata.
Automatic annotation of complex documents is still a hard problem for computational
systems, hence any support to the manual work of the human annotators,
for example, retrieval of existing information or versatility in managing different
types of media is helpful. Moreover multimedia documents can be both the subject
and the content of the annotation, making the combined management of documents
and annotations a must. On the other hand, as we focus on in this chapter, annotation
can prove useful not only for wide communities, but also for groups of interest
or at the enterprise level, or even for individuals, allowing them to accumulate
knowledge on specific topics by constructing a web of annotations.
In this sense, the annotation activity can be used to extract and retrieve two types
of information. In the first type, which we may call “objective,” well-known facts, for
example, dates, places, or names, are extracted, which need to be related, structured,
and documented, possibly according to known, domain-dependent conventions. Ithe second, “subjective,” type, the information which is extracted is related to the
user’s goal in the context of a particular activity. Users may want to associate different,
possibly unrelated parts of a document, such as salient features of an event
or location, or of the psychological profile of a person, or information about a
product or service, with a view to what is needed for a given task, for example, a
presentation, a lecture, or the construction of a personal archive. Moreover, they
want to do so in a nondisruptive way, while perusing the document.
The MADCOW system (for Multimedia Annotation of Digital Content Over the
Web) (Bottoni et al. 2004, 2006), allows users to annotate web pages containing
different types of media with web notes composed of text, images, video, and, in
general, any type of digital document, which can then be retrieved from the originally
annotated document (or directly through queries to an annotation server), and
which can be made public. The MADCOW client is integrated as a bookmarklet on
the toolbar of the most common browsers and allows readers to create or retrieve
annotations on the current page without interfering with their normal behavior
when accessing information on the Web.
We have recently enriched MADCOW with the ability to create notes pertaining
not only to single blocks of text or to structures within pictures contained in the
page, but also referring to any combination of these individual elements. As an
example, writers involved in the cooperative construction of a web page, or a scholar
reading a scientific document, could create a single note on two portions of text that
appear as contradictory, or as a repetition. A detailed analysis of a picture might
immediately refer to the text describing it. More sophisticated uses might uncover
the logical relations between different parts of the document as described in the
first scenario presented in the paper. These actions need not be done by the author
of the document, but provide a dynamic construction of the interpretation of the
document by its readers, in a sense materializing the notion of “open work” (Eco
1962). To our knowledge, no existing system for manual web annotation tackles the
problem of linking a single annotation to different portions of the document.
In the following, we introduce our running example on two scenarios, concerning
cooperative enrichment of available material between teacher and students,
and extraction of structured information by a single user, illustrating the use of
MADCOW to organize the two types of information discussed above. We present
the notion of multistructure, allowing the creation of multi-notes, which associate a
single annotation with several elements of a Web document, and present the relevant
data structures and the interaction by which they are created exploiting the
MADCOW client. Finally, we show how multi-notes can further be manipulated
and reused by readers accessing them
Effect of Weed Management Methods on the Growth and yield of Ginger in Metu, Illubabor Ethiopia
No full textA field experiment on ginger weed management was conducted at Metu from2009 and 2011 with the objective of identifying effective weed management for ginger under Metu condition. Different weed management methods were compared in a Randomized Complete Block Design with three replications. The treatments were: hand weeding at 30,60,90, days after planting, .hand weeding at 45,75,105,135 &165 days after planting, hand weeding at 60,90,120,& 150 days after planting, mulching at planting followed by hand weeding at 45 and 75 days after planting, . mulching at planting followed by hand weeding at 60 and 90 days after planting, hand weeding at 30 and60 days after planting followed by mulching followed by one hand weeding as needed, The result showed that the major weeds at both locations were: Cynodon spp., Cyprus spp., Digitaria spp., Gyzotia scabra, Bidens polynchyma, Nicandra physaloides, Commelina spp., Bidens pilosa, and Ageratum conyzoides. hand weeding at 30 and60 days after planting followed by mulching followed by one hand weeding as needed, hand weeding at 45 and 75 followed by mulching followed by one hand weeding as needed and weed free and weedy controls.The result reveled a highly significant (p < 0.01) difference between treatments The result showed that as weeding frequency increased yield of ginger also increased. One early hand weeding between 30 and 45 days was critical to secure high yield of ginger. Mulching at planting followed by two hand weeding at 60 and 90 days after planting gave higher yield compared with the clean weeding treatment. Similarly hand weeding at 30 and 60 days followed by mulching and followed by one hand weeding also gave similar yield with clean weeding. Mulching at planting enhanced early germination and growth of ginger compared with non mulched ginger. On the other hand, the result also showed that ginger was poorly competed with weeds that when the first hand weeding was delayed from 30 to 45 and 60 days after planting ginger growth was affected resulting in tremendous yield loss. The result also clearly showed that three hand weeding at 30,60 and 90 days after planting was not adequate under Metu condition. When weeding was totally ignored throughout the growing period yield reduction amounted 95.5 %
