Optimal Osmotic Dehydration of Piece-form Mango in a semi-continuous operation
Osmotic dehydration of mango fruits (Mangifer indica L.) is directed towards reduction of its seasonal losses at glut. Effects of sucrose concentrations; 40 to 65°Brix; temperatures; 30 to 50 ºC and time of immersion between 0 to 180 min were studied using samples of diced mango cubes of 2 cm3 dimensions. The measured response variables of water loss, solute gain and performance ratio were subjected to statistical analysis. The results were modelled and optimised on the premise of maximum WL and minimum SG and maximum PR as constraints using the modified distance approach of the response surface methodology (Design Expert 6.08). Optimal osmotic dehydration evaluated were 59.19oBx, 32.06oC and 156.min. of 53.03°Bx sucrose concentration yielded 42.32% WL, 3.41% SG and PR of 10.69 with a desirability of about 89.73%. The results showed that all the input process variables had a significant effect at 5% level of significance (P < 0.05). Optimal process conditions adopted in a semi-continuous pilot plant yielded about 47 (%) water loss and 7.1 (%) solute gain of the initial sample content. The system proved efficient in the treatment of mango with performance ratio in the range of 3 – 7 and could be used in the food industry for the preservation of fruits. More so, the model could be used to predict operational conditions for the OD of other similar fruits. Running title: Optimal osmotic dehydration of mango cubes

Quantum chemical calculations of pyridine-2,6-dicarbonyl dichloride
The solid phase FT-IR and FT-Raman spectra of pyridine-2,6-dicarbonyl dichloride (PDD) have been recorded in the regions 4000-400 cm-1 and 3500-100 cm-1, respectively. Geometry and vibrational wavenumbers are calculated using ab-initio Hartree-Fock (HF) and Density Functional Theory (DFT) methods employing the 6-311+G (d,p) basis set. The observed FT-IR and FT-Raman vibrational frequencies have been analyzed and assigned to different normal modes of the molecule. Using PEDs, the contributions are determined for different modes to each wavenumber.

Reading Strategies in Iranain EFL learners
Reading strategies are of interest for what they reveal about the way readers manage their interaction with written text and how these strategies are related to text comprehension. The aims of this study is to compare using of metacognitive strategies in reading skill by advanced, intermediate and elementary levels learners of English language. 200 Iranian EFL students both male and female were participated in this study. Their language proficiency level was classified to elementary, intermediate and advanced learners. It is convincing to mention that the participants were English major in teaching, translation and literature. The researcher utilized a questionnaire which was 22 items based on Likert Scale. The metacognitive reading strategies questionaire (MRSQ)is administered to investigate the frequency of participants'useof metacognitive reading strategies developed by Taraban,Kerr and Rynerson (2004). The results of the chi-square indicate that there is a significant relationship between the proficiency level of the students and their use of meta-cognitive strategies (x2 (8) = 74.67, P = .000 < .05). That is, as proficiency level increases the students make more use of meat-cognitive strategies. It should be also noted that gender as an independent variable in this study didn't cause any significant difference in the performance, i.e., we can claim that no significant differences between male and female students exist regarding the use of metacognitive strategies.

Relationship of Landscape Positions with Soil Properties on Maize (Zea Mays L.) Yield in Ultisol
Relationship of landscape position and soil properties to maize (Zea mays L.) yield was studied in coastal plain soils of Akwa Ibom state. The study aimed at assessing the physico-chemical soil attributes down the geomorphic surface as well as assessing the yield of maize in the respective landscape positions. A total of 3600 plant population (hybrid maize) were planted on 0.072ha in a Randomized complete block design. The traditional land preparation technique was employed after slashing the re-growth vegetation with cutlass. The trashes was left on the sites and allowed to dry for three weeks before burning. Pre-burn soil samples were taken before burning the trashes at the end of three weeks after slashing. The samples collected were analyzed in the laboratory for physico-chemical properties using standard methods (ASTM and IITA). Collected data were statistically analyzed and means of statistically significant parameters were separated using LSD (0.05). The results showed that sand particle of burnt and un-burnt soils were significantly different at 0-15cm of Upper slope (US) but not significantly different in other landscape positions (p<0.05). Soil pH in burnt soil was significantly different from the un-burnt soil (both at surface and sub surface) in the three landscape positions. Mean maize yields (with husk) was 0.09 and 0.11kg/ha ‘before’ and ‘after’ burning plots of US ; 0.12 and 0.16kg/ha in ‘before’ and ‘after’ burning plot of the middle Slope (MS) while the Bottom valley (BV) had 0.14 and 0.16kg/ha in ‘before’ and ‘after’ burning plots. Altogether, both husked and de-husked yields were higher in burnt plots than un-burnt plots. Along the slope, husked yield followed the order: BV (0.15kg/ha) > MS (0.14kg/ha) > UP (0.10kg/ha)) while de-husked yield also followed similar pattern but different magnitude.
