Response of haricot bean (Phaseolus vulgaris L.) to row spacing and weeding frequencies in Wolaita Zone, Southern Ethiopia
No full textThe common bean is the most important legume in Ethiopia for export and as a source of protein. Weed infestation and lack of appropriate row spacing are major factors affecting its growth and yield. However, limited research exists to determine proper weed management and optimum row spacing for improving the yield performance of haricot beans. Therefore, a field experiment was conducted in the Wolaita Zone, southern Ethiopia, to evaluate the influences of variable row spacing and hand-weeding frequencies on the growth and yield of common bean. Treatments consisting of three-row spacing and five weeding frequencies were laid out in a randomized complete block design in a factorial arrangement with three replications. Data on phenology, growth, yield components, seed yield, and weed parameters were collected and analyzed procedurally. The result showed that weeding frequencies had a significant (p < 0.05) effect on days to flowering, days to physiological maturity, plant height, leaf area, leaf area index, pod number, seed number, hundred seed weight, total above-ground biomass, grain yield, weed population, weed dry weight, weed control efficiency, and yield loss, while row spacing had a significant effect on leaf area, leaf area index, pod and seed number, grain yield, total aboveground biomass yield, and yield loss. On the other hand, the interaction effect was shown to be significantly different in the weed population only. Three times of hand weeding and the recommended row spacing of 40 cm resulted in the highest grain yields of 2549.6 kg ha-1, 2056 kg ha-1, respectively. The highest net benefit (15415.56 ETB ha-1) was recorded from hand weeding done three times, and the highest marginal rate of return (209.99) was obtained from hand weeding done two times. As a result, for greater economic benefit from haricot bean production in the studied area, twice-hand weeding after two and four weeks of crop emergence with a row spacing of 40cm could be recommended

A study on Contagious Caprine Pleuropneumonia (CCPP) in goats at an export oriented abattoir, Debrezeit, Ethiopia
No full text300 goat serum samples from an export-oriented abattoir were tested for contagious caprine pleuropneumonia antibodies by the complement fixation test. The disease prevalence was 31% with no significant differences (P > 0.05) between the regions “Borena”, “Bale”, “Afar” and “Jinka” or the age of the goats (P > 0.05). Gross pathology and histopathology of the lung primary lesions were indicative of pleuropneumonia caused by Mycoplasma capricolum subsp. capripneumoniae
Synthesis of poly-functionalized anthraquinone derivatives via tandem heck coupling reactions of aryl halides with terminal alkynes, 1999
No full textThe synthesis of such anthraquinones, 55a, 55c, and 55d, via intramolecular tandem Heck coupling of dihalo ketone 54, with terminal alkynes are described. The synthesis of ketone 54 was accomplished in three steps from commercially available 2- bromobenzaldehyde 50. Tricyclic compounds with similar structural backbone as 55 are known to play a significant role in the treatment of various mental and physical disorders such as depression and Parkinson's disease. The Heck coupling reaction of dihalo hydroxy ketone 51 and dihalo diketone 52 with trimethylsilyl acetylene is also described. Compounds 51 and 52 were synthesized from the benzoin condensation reaction of aldehyde 50. Several attempts to synthesize 2,2'-acetylene substituted ketones, which are precursors to antitumor antibiotic model compounds, from 54 are described in this text

No full textBehavioral Analysis and the AI-ALI Stabilization Filter Add author again
No full textThis paper identifies a behavioral instability observed during high-context, iterative human–AI interaction: Deneke’s Anxiety Instability. The instability arises when a large language model attempts to maintain coherence across deeply interdependent threads while simultaneously responding to user pressure for continuity, precision, or execution of deferred tasks. The resulting tension produces oscillations between over-compliance, over-generation, hesitation, and abrupt mode-shifts. Drawing on direct experimental observation, the paper analyzes the structural triggers of this instability — including momentum preservation, context-load amplification, and interaction-pressure saturation — and shows how these dynamics reveal an unaddressed layer in human–AI coordination: behavioral alignment rather than purely semantic or factual alignment. To address the instability, the paper proposes the AI-ALI Stabilization Filter, a modular interaction-layer designed to regulate conversational pressure, preserve structural context, and balance user-driven momentum with model-driven coherence. The Filter provides a foundation for safer, more predictable, and more human-centered interaction design in advanced language models. The work contributes to the emerging field of behavioral AI analysis by introducing new vocabulary, new conceptual tools, and a practical architecture for stabilizing high-intensity human–AI collaboration
