Agro-Morphological, Physiological and Yield Related Performances of Finger Millet [Eleusine coracana (L.) Gaertn.] (Poaceae) Accessions Evaluated for Drought Resistance under Field Condition
No full textThis study was conducted on the understanding that a comprehensive study of the impact
of drought stress and screening crop accessions for drought resistance is critical in
evaluating the impact of climate change and climate variability on crop production. The
study was conducted in Dhera Sub center of Kulumsa Agricultural Center, Oromia
Regional State, from July 10- December 13, 2011; to screen drought tolerance of 96
finger millet accessions (Eleusine coracana L. Gaertn.) for their performance under
severe drought condition. Data were collected for morphological trait and physiological
measurement. Significant difference (P<0.05) were recorded among accessions for
selected physiological, morphological and yield related traits used for screening finger
millet accessions for drought resistance. This implies there was variations among
accessions collected from different agroecology for different target traits and provide
opportunity to select accessions for different agroecology. (RWC), Chlorophyll Content
Index (CCI) and yield related parameters, such as tillers number (TN), productive tillers
(PT), seed weight per head and seed weight per plant. Based on high RWC, and CCI
reading, higher root shoot ratio, green leaf number, productive tillers, ear length, ear number, grain yield per head and per plant. Based on the above parameters a total of 23
accessions were selected for their performance of drought stress tolerant and promoted
to the next intensive physiological and yield evaluation. 238299, 238325, AAUFM-2,
were the top three accessions which gave the highest grain yield per plant (84.5, 80 and
77.5(g), respectively. Overall this research should be further utilized for improvement of
finger millet for semi-arid area of Ethiopia
Awol A: Traditional medicinal plants used by people in Libo-Kemkem district
No full textAbstract: The present study was conducted between June 2010 and September 2010, to document medicinal plant species traditionally used by peoples in Libo-kemekem district, South Gondar, Ethiopia. Ethnobotanical data were collected using semi structured interviews, focused group discussion and field observations. A total of 52 medically important plants belonging to 45 families and 47 genera were identified in the district. Majorities (47.37%) were collected from wild. Most of the plants (94.23%) were reportedly used to treat human diseases. The most frequently used plant parts were leaves (40.38%), followed by fruits (23.08%) and roots (17.31%). Local people depend on both dry and fresh remedies. The administration routes were oral (57.69%), dermal (25.00%), nasal (11.54 %) and anal (5.77%). The preference ranking showed that Lantana camara was the most important species in treating diarrhea followed by Vernonia amygdalin indicating high utility value of the species in the community. The results revealed existence of diverse medicinal plants and indigenous knowledge in the study area. Therefore, documenting medicinal plants and associated indigenous knowledge can be used as a basis for developing management plans for conservation and sustainable use of medicinal plants in the area

No full textThe study was conducted at Dhera Sub-center of Kulumsa Agricultural Research Center, Oromia Regional State, Ethiopia from July - December 2011; to screen drought tolerance of 96 finger millet accessions (Eleusine coracana L. Gaertn.) collected from different agro-ecological zones of the country. Data were collected for plant height (PH), green leaf number (GLN), green leaf area (GLA), ear number (EN), ear length (EL) and relative water content (RWC). Significant difference (P<0.05) were obtained between accessions for most selected physiological, morphological and yield related traits such as Chlorophyll Content Index (CCI), RWC, and yield related parameters, such as tiller number (TN), productive tillers (PT), seed weight per head and per plant. Based on high RWC, CCI, GLN, PT, EL, and EN, Grain Yield per head and per plant, a total of 23 accessions were categorized as drought stress tolerance and promoted to the next intensive physiological and yield related evaluation. Moreover, AAUFM-7, AAUFM-2, AAUFM-44 were the first top three accessions with the highest grain yield of 77.5, 72g/plant and 65.4g/plant, respectively. Overall, the higher genetic variability observed among accession in this study should be further utilized for finger millet improvement targeting semi-arid areas of Ethiopia
Modeling the Impact of Climate Change on Sustainable Production of Two Legumes Important Economically and for Food Security: Mungbeans and Cowpeas in Ethiopia
No full textClimate change is one of the most serious threats to global crops production at present and it will continue to be the largest threat in the future worldwide. Knowing how climate change affects crop productivity might help sustainability and crop improvement efforts. Under existing and projected climate change scenarios (2050s and 2070s in Ethiopia), the effect of global warming on the distribution of V. radiata and V. unguiculata was investigated. MaxEnt models were used to predict the current and future distribution pattern changes of these crops in Ethiopia using different climate change scenarios (i.e., lowest (RCP 2.6), moderate (RCP 4.5), and extreme (RCP 8.5)) for the years 2050s and 2070s. The study includes 81 and 68 occurrence points for V. radiata and V. unguiculata, respectively, along with 22 environmental variables. The suitability maps indicate that the Beneshangul Gumuz, Oromia, Amhara, SNNPR, and Tigray regions are the major Ethiopian regions with the potential to produce V. radiata, while Amhara, Gambella, Oromia, SNNPR, and Tigray are suitable for producing V. unguiculata. The model prediction for V. radiata habitat ranges distribution in Ethiopia indicated that 1.69%, 4.27%, 11.25% and 82.79% are estimated to be highly suitable, moderately suitable, less suitable, and unsuitable, respectively. On the other hand, the distribution of V. unguiculata is predicted to have 1.27%, 3.07%, 5.22%, and 90.44% habitat ranges that are highly suitable, moderately suitable, less suitable, and unsuitable, respectively, under the current climate change scenario by the year (2050s and 2070s) in Ethiopia. Among the environmental variables, precipitation of the wettest quarter (Bio16), solar radiation index (SRI), temperature seasonality (Bio4), and precipitation seasonality (Bio15) are discovered to be the most effective factors for defining habitat suitability for V. radiata, while precipitation of the wettest quarter (Bio16), temperature annual range (Bio7) and precipitation of the driest quarter (Bio17) found to be better habitat suitability indicator for V. unguiculata in Ethiopia. The result indicates that these variables were more relevant in predicting suitable habitat for these crops in Ethiopia. A future projection predicts that the suitable distribution region will become increasingly fragmented. In general, the study provides a scientific basis of suitable agro-ecological habitat for V. radiata and V. unguiculata for long-term crop management and production improvement in Ethiopia. Therefore, projections of current and future climate change impacts on such crops are vital to reduce the risk of crop failure and to identify the potential productive areas in the country
Absence without official leave (AWOL)
No full textAn employee who absents himself from the workplace on a scheduled workday, will inevitably disrupt the employer’s
work schedules, aside from affecting the employer’s customer
commitments, amongst other things. To minimise the work disruption due to the slack caused by an absent employee, a regular worker would in normal circumstances assume the added workload. unless and until the annual leave request has been formally and properly approved by the employer, an employee should not absent himself from work. An unauthorised absence from the workplace without
any prior approval or permission of the employer is an outright violation of discipline. Hence, in this paper the author argued that a worker who absents himself from work for two or more consecutive days without leave or permission, who exceeds his leave beyond the sanctioned period or who is absent from his place of work without permission, is said to have committed a gross misconduct, and if the allegation is established, the employer is entitled to impose appropriate punishment up to and including dismissal
Seed Germination Enhancement of Two Balanites Species (B. aegyptiaca (L.) Del. and B. rotundifolia (Tiegh.) Blatt.) Using Different Presowing Treatments in Ethiopia
No full textB. aegyptiaca and B. rotundifolia are known to be multipurpose trees with various uses and values. Therefore, the aim of this study was to investigate the seed germination behaviours of B. aegyptiaca and B. rotundifolia under different presowing treatments. Hence, seeds were collected from the Central and Southern Ethiopian Rift Valley regions. Then, a total of 864 fruits (seeds) subjected to eight different presowing treatments and planted in pots arranged in a completely randomized design (CRD) were tested for each species. The mean germination percentage (GP), mean daily germination percentage (GD), mean germination time (GT), and mean germination index (GI) were computed. One-way ANOVA showed the presence of significant GP, GD, GT, and GI among treatment groups at p<0.05 under both Balanites species. For B. aegyptiaca, Tukey’s HSD test showed that seeds soaked with 98% H2SO4 for 10 minutes (98HSO10m) and 20 minutes (98HSO20m) have the highest GPs (87 ± 8.8 and 82 ± 10.2, respectively) that are significant at p<0.05. The seeds soaked in 75°C hot water for 10 minutes and subsequently cooled for 12 hours (HW75d), 98HSO10m, and 98HSO20m have the highest GDs (2%) that are significant at p<0.05. Moreover, 98HSO20m, 98HSO10m, and seeds soaked in cold water for 48 hours at room temperature of 25°C (CW48h) have the shortest GTs (24 ± 2.2, 25 ± 0.5, and 25 ± 1.3, respectively), and 98HSO10m and 98HSO20m have the highest GIs (1.04 ± 0.09 and 1.01 ± 0.08, respectively) that are significant at p<0.05. For B. rotundifolia, the control recorded the highest cumulative germination (i.e., 71), followed by CW48h (i.e., 51). However, Tukey’s HSD tests generally indicated that no treatment group resulted in significant differences in the means of GP, GD, GT, and GI at p<0.05. So, no treatment group was observed to enhance the germination of B. rotundifolia compared to the control. However, this study generally indicated potential seed enhancement technologies for B. aegyptiaca with greater implications for propagation, conservation, and sustainable utilization of the species in the agricultural and pastoral communities of Ethiopia

No full textAnalysis of Semantic Web Technology and Web Ontology for Digital Library Service
No full textThe broad concept of digital libraries ideally represents the needs of heterogeneous
information resources combining the development of complex systems issues such as
interoperability among existing data providers, distributed retrieval, and long-term
preservation. These days most of the existing web-based digital libraries offer search as well
as navigation services. Search services are mainly based on a set of metadata such as domain
related keywords, author, title, or journal name that carries no semantic information for the
search engine. Besides, digital libraries may support graphical user interfaces to aid the
formation of queries in order to search documents. Queries can contain one or more domain
keywords to be searched in the full text document, or in one of the metadata fields. This study
aimed to harness the collective knowledge within communities in digital libraries, improving
the discovery and dissemination of knowledge through ontologies. The study is intended to
analyze the semantic web technology and web ontology–based language application for
sharing knowledge through digital library service. The design science and exploratory
research methodology is employed in this study to explore and analyze semantic web and
ontology. In this study the researcher have evaluated the effect of semantic web technology
and web ontology language for digital library service. The study analyzed various digital
library services with the support of semantic web technologies. Mainly, digital libraries have
been benefited from ontology language, semantic web and syntactical features in order to
enhance the searching capabilities of their systems. To do so, in this study the researcher
have discussed all the digital libraries searching strategies and come up with a new integrated
robust framework with the help of domain specific ontologies and semantic sentence
embedding approach. The study has used an existing ontology for infectious disease portal in
order to extract dictionaries of terms, concept relationships and properties. On the other hand,
the researcher used the capabilities of sentence embedding techniques on the top of rich set of
pre trained vocabularies and pre trained models In order to evaluate the propose framework
the researcher prepared a small size dataset on domain specific communicable diseases. The
dataset consists of relevant metadata of articles such as author, title, Uniform Resource
Locater, abstract, Internatiol Standard of Book Number, year of publication, and disease term
or vocabularies. The Semantic web provides a common framework that allows data to be
shared and reused across application, enterprise, and community boundaries. In addition, the
semantic web has played a significant role to improve the efficiency of different search
engines including digital library systems
The Labyrinth Of The Mind: The Psychology Of War Stories In Tim O’Brien’s Going After Cacciato
No full textThis paper explores and analyzes the psychological reasons for storytelling by soldiers and veterans both during and after their deployments in war. It brings in multiple works by author-veterans as well as critical writing about these books with a specific focus on Going After Cacciato by Tim O\u27Brien. Paul Berlin, the novel\u27s protagonist, imagines a fictional quest leaving Vietnam and going all the way to Paris following the desertion of a fellow soldier gone AWOL. He creates this journey to create order, find meaning, generate understanding, and focus on the good rather than the bad. This paper also explores the effects of Post Traumatic Stress Disorder on the storytelling of soldiers in order to connect the disciplines of English Literature and Psychology
