We describe various computing techniques for tackling chessboard domination problems and apply these to the determination of domination and irredundance numbers for queens’ and kings’ graphs. In particular we show that γ(Q15) = γ(Q16) = 9, confirm that γ(Q17) = γ(Q18) = 9, show that γ(Q19) = 10, show that i(Q18) = 10, improve the bound for i(Q19) to 10 ≤ i(Q19) ≤ 11, show that ir(Qn) = γ(Qn) fo...

Our data suggest a novel mechanism whereby pathological-length polyglutamine (polyQ) proteins promote the spermine synthetic pathway, increasing polyQ-aggregation and cell death. As detected in a cell-free turbidity assay, spermine promotes aggregation of thio-polyQ62 in a dose-dependent manner. Using a stable neuronal cell line expressing pathological-length [polyQ57-yellow fluorescent protein...

Recent evidence suggests that, in huntingtin and many other proteins, polyglutamine repeats are a toxic stimulus in neurodegenerative diseases. To investigate the mechanism by which these repeats may be toxic, we transfected primary rat cerebellar granule neurons with polyglutamine-green fluorescent protein (GFP) fusion constructs containing 19 (Q19-GFP), 35 (Q35-GFP), 56 (Q56-GFP), or 80 (Q80-...

Plant productivity relies on photosynthesis, and the photosynthetic process relies on phosphorus (P). The genetic basis of photosynthesis and P efficiency (PE) affecting yield has been separately characterized in various crop plants. However, the genetic relationship between PE and photosynthesis remains to be elucidated. In this study, we used a combined analysis of phenotypic correlation, lin...

In this paper an applied general equilibrium model for the Extremadura region is presented. Our aim is to show the importance of agricultural subsidies in this economy, that it is a distinctive characteristic of this region. To achieve this purpose, we analyse the effects of a supression of these subsidies, using different scenaries related to the labour market and tax compensation. Model param...

In addition to providing food benefits, urban agriculture also has aesthetic benefits. Therefore, a visual assessment of the agricultural landscape can be used measure this value. Gender preference is carried out see differences in assessment. This research was conducted Makassar City using primary data with 129 respondents consisting 53 people who had never been and 76 been/lived Makassar. The...

Although limited proteolysis of the histone H3 N-terminal tail (H3NT) is frequently observed during mammalian differentiation, the specific genomic sites targeted for H3NT proteolysis and the functional significance of H3NT cleavage remain largely unknown. Here we report the first method to identify and examine H3NT-cleaved regions in mammals, called chromatin immunoprecipitation (ChIP) of acet...

This study assesses the agricultural commercialization levels, determinants, and challenges confronting smallholder cassava farmers in Oyo State, Nigeria. was conducted Nigeria using cross-sectional data from 211 employing multi-stage sampling procedures. Descriptive statistics, Crop Commercialization Index (CCI), Ordered Logit Model (OLM) were used to analyze collected. The results revealed th...

(Note that the Craig interpolation theorem is the special case of Chang's theorem in which Q19,.., Qn are all universal quantifiers.) Chang also raised the question [2, Remark (k)] as to whether the Lopez-Escobar interpolation theorem [6] for the infinitary language L.1. possesses a similar generalization. In this paper, we show that the answer to Chang's question is affirmative and, moreover, ...
