Published: December 2015

<p>The basic purpose of this study has been to examine the relationships between metacognitive awareness and maths anxiety in gifted students. The second aim was to compare with gifted and non-gifted students’ metacognitive awareness and maths anxiety levels. The participants were 300 (150 gifted, 150 non-gifted) volunteer secondary school students in Turkey. The mean age of the participants was 12.56 years ranging from 12 to 13 years. For gathering data, the Maths Anxiety Scale for Elementary School Students and The Metacognitive Awareness Inventory for Children were used. For analysing the data, Spearman correlation analysis, the Mann Whitney U test, and linear regression analysis were used. According to the findings: firstly, gifted students’ metacognitive awareness scores were higher than those of non-gifted students. On the other hand, non-gifted students’ maths anxiety levels were higher than those of gifted students. Secondly, there was negative correlation between metacognitive awareness and math anxiety. Finally, the findings of linear regression analysis indicated that metacognitive awareness is explained by 48% total variance of maths anxiety in gifted students.</p><p> </p><p>Keywords: Metacognitive awareness, maths anxiety, gifted</p><p> </p><p> </p>

ABSTRACTSince 1980, 150 North Carolina State University (NCSU) maize (Zea mays L.) inbreds have been developed and released on the basis of superior performance for topcross yield and other traits of agronomic importance. During this time, there has been great emphasis placed on breeding with exotic germplasm, with 86 NCSU inbreds having at least 50% exotic parentage and 40 of those having all‐tropical parentage. Maize germplasm released by NCSU represents a potentially useful resource for increasing maize diversity and performance in the United States. The objectives of this study were to characterize the genetic relationships among inbreds released from this unique breeding program and to compare them genetically with inbreds from other public and private breeding programs. The NCSU maize inbreds can be classified into five germplasm pools: Lancaster, Temperate‐adapted all tropical (TAAT), Lancaster × Tropical, Stiff Stalk, and Southern non‐Stiff Stalk; detailed analysis of pedigree records and molecular marker genotypes reveals additional substructure within each of these pools. There is general agreement among the four cluster analyses performed, three using single nucleotide polymorphism (SNP) data and one using pedigree‐derived coefficients of coancestry. We introduce a novel application of Procrustes analysis to identify disagreements between pedigree and marker similarities. The NCSU maize breeding germplasm includes diverse genetic backgrounds, as evidenced by the number of unique alleles compared with publically available inbreds from both public and off‐protection, private‐sector sources.

ABSTRACTObjective: To determine whether trumpet performance skills are associated with malocclusion.Materials and Methods: Following institutional review board approval, 70 university trumpet students (54 male, 16 female; aged 20–38.9 years) were consented. After completing a survey, the students were evaluated while playing a scripted performance skills test (flexibility, articulation, range, and endurance exercises) on their instrument in a soundproof music practice room. One investigator (trumpet teacher) used a computerized metronome and a decibel meter during evaluation. A three-dimensional (3D) cone-beam computerized tomography scan (CBCT) was taken of each student the same day as the skills test. Following reliability studies, multiple dental parameters were measured on the 3D CBCT. Nonparametric correlations (Spearman), accepting P &lt; .05 as significant, were used to determine if there were significant associations between dental parameters and the performance skills.Results: Intrarater reliability was excellent (intraclass correlations; all r values &gt; .94). Although associations were weak to moderate, significant negative associations (r ≤ −.32) were found between Little's irregularity index, interincisal inclination, maxillary central incisor rotation, and various flexibility and articulation performance skills, whereas significant positive associations (r ≤ .49) were found between arch widths and various skills.Conclusions: Specific malocclusions are associated with trumpet performance of experienced young musicians.

Published: December 2015

ABSTRACTObjective: To test the hypothesis that there is no difference between the biocompatibility and degree of monomer conversion of flowable resins used as bioprotective materials of orthodontic mini-implants.Materials and Methods: Forty-eight male Wistar rats were divided into four groups (n  =  12). Group Control (polyethylene), Group Wave, Group Top Comfort, and Group Filtek. The animals were sacrificed after time intervals of 7, 15, and 30 days and tissues were analyzed under optical microscopy for inflammatory infiltrate, edema, necrosis, granulation tissue, multinucleated giant cells, and collagen formation. The degree of conversion was evaluated by the Fourier method. Biocompatibility and degree of conversion were evaluated by the Kruskal-Wallis and Dunn tests, and analysis of variance and the Tukey test, respectively (P &lt; .05).Results: An intense inflammatory infiltrate was observed on the seventh day, with Groups Top Comfort and Filtek differing statistically from Group Control (P  =  .016). Edema, necrosis, granulation tissue, and giant cells showed greater expressiveness at 7 days, without statistical difference between them (P &gt; .05). For the presence of collagen fibers, Group Top Comfort was shown to differ statistically from Group Control (P  =  .037) at 15 days and from Groups Filtek and Control (P  =  .008) at 30 days. Monomer conversion ranged from 62.3% in Group Top Comfort at 7 days to 79.1% in Group Filtek at 30 days.Conclusions: The hypothesis was rejected. The resin Top Comfort demonstrated lower tissue repair capacity with a lower number of collagen fibers compared with Filtek and Wave resins. The resin Top Comfort showed the lowest conversion values during the experiment.

Abstract
Thirty-six Angus-cross steers (667 ± 34.4 kg initial BW, 24.5 mo) were used to assess the impact of short-term glycerin or high-fructose corn syrup administration via drinking water on meat quality and marbling deposition. Steers blocked by BW (3 blocks) were assigned randomly to 1 of 3 drinking water treatments: 1) control (CON), 2) 4.3% crude glycerin (GLYC), or 3) 4.3% high-fructose corn syrup (HFCS) for the final 25 d before slaughter. Average daily gain was lower (P = 0.01) and final live weight was lower (P &lt; 0.01) with HFCS administration compared with CON. Dry matter intake and water intake did not differ among treatments. Fat thickness, muscle depth, and intramuscular fat measured by ultrasound did not differ among treatments. Crude glycerin or HFCS via water supplementation did not alter HCW, dressing percentage, rib eye area, fat thickness, KPH, skeletal maturity, or marbling score. Longissimus muscle and subcutaneous fat color (L*, a*, and b*) were not affected by drinking water treatment. Total lipid content, total fatty acid content, and fatty acid composition of the LM did not differ among drinking water treatments. Supplementation of drinking water with GLYC or HFCS did not alter Warner-Bratzler shear force values or water-holding capacity (drip loss, cook shrink). Intramuscular mean adipocyte diameter was greater (P = 0.02) for steers offered HFCS compared with steers offered GLYC, with CON steers being intermediate. These differences in mean adipocyte size were related to changes in the adipocyte size distribution. There were greater proportions of small (20 to 30 μm) adipocytes in GLYC compared with HFCS and CON. In contrast, HFCS and CON had greater proportions of medium (40 to 50 μm) adipocytes than GLYC. The relative mRNA expression of lipogenic genes (acetyl Co-A carboxylase [ACC], fatty acid binding protein 4 [FABP4], fatty acid synthase [FASN], glycerol-3-phosphate acyltransferase [GPAT], retinol-binding protein 4 [RBP4], and stearoyl-CoA desaturase [SCD]), adipocyte differentiation genes (delta-like 1 homolog [DLK1]), and transcription factors (CCAAT/enhancer-binding protein α [C/EBPα], and PPARγ) was similar for GLYC and HFCS compared with CON. Longissimus glycogen and lactate concentrations and glycolytic potential were not affected by drinking water treatments. Overall, HFCS or GLYC supplementation via drinking water did not alter carcass or meat quality variables but did alter the size and distribution of intramuscular adipocytes. These results indicate that a longer supplementation time or a higher substrate level may be needed to obtain differences in meat quality.

An experiment was conducted at the Bangladesh Jute Research Institute (BJRI), Regional Station, Kishoreganj, Bangladesh during July to December 2010 and 2011 to study the effect of spacing and time of de-topping on yield and quality of kenaf seed cv. HC-95 grown under transplanting method. The experiment comprised three plant spacing (viz., 40 cm × 15 cm, 30 cm × 15 cm and 20 cm × 15 cm) and five de-topping (viz., no de-topping, de-topping at transplanting, de-topping at 15, 30 and 45 days after transplanting (DAT) in a Randomized Complete Block Design (RCBD) with three replications. The highest yield of kenaf seed was obtained from planting at 30 cm × 15 cm spacing. The best quality seed in respect to germination and vigour was also obtained from transplanting at 30 cm × 15 cm spacing. The highest seed yield, germination and vigour of seed were obtained for de-topped at 30 DAT. The study concludes that late season kenaf produces highest seed yield with best quality when planted at 30 cm x 15 cm spacing and for de-topping at 30 DAT.

Published: December 2015

Two field experiments had been conducted in Nubaria sandy soil, Behaira Governate, Egypt to show the effect of keratinase enzyme produced by the novel microbial isolate (Cyberlindnera fabianii NRC3 Aza) on plants.The trials had been conducted in the two successive summer seasons (2011/2012 and 2012/2013) to show the effect of keratinase enzyme from degraded feather–waste on the morphology and chemical composition of peas pods (Pisumsativum L.)–family Fabaceae (Leguminasae). In 2011/2012 season, only the chemical analysis of the dried powdered beads was studied. In 2012/2013 season, the morphological studies of the yield were considered beside the chemical ones. The results depicted significant effects of the sprayed enzyme (keratinase) on peas as plant growth promoting agent (PGPA), compared with the blank (sprayed with water). Electrophoreses and amino acid analysis were carried out for the characterization of the partial pure keratinase enzyme. Int J Appl Sci Biotechnol, Vol 3(4): 609-618

Published: December 2015

Adverse environmental factors like drought stress result in increased levels of ROS that adversely affect the growth and productivity of plants. The alleviation of oxidative damage and increased resistance to environmental stresses is correlated with an efficient antioxidant system. Antioxidant non enzymatic system as well as enzymatic system neutralize the effects of these reactive oxygen species and help plants to survive in stress conditions. The study was carried out with the aim to understand the effect of drought on antioxidant system in seedling and vegetative stages of drought tolerant as well as sensitive genotypes of Eleusine coracana. Drought was imposed by withholding water for 8 days at seedling and vegetative stages of drought tolerant ie PRM-6107 and sensitive ie PES-400 genotypes of E. coracana. Different enzyme assays and biochemical analysis were performed in leaf samples by following the standard protocols. With the induction of drought, an increment in the level of ascorbate, flavonoid, phenol and proline was recorded in PRM-6107 whereas no significant increase was observed in PES-400. The level of these antioxidants was more in seedling stage than at vegetative stage. Similarly the level of antioxidant enzymes like ascorbate peroxidase, catalase, guaicol peroxidase, superoxide dismutase and glutathione reductase was high in tolerant genotype as compared to sensitive genotype under unstressed condition. Under stress condition, the level of catalase, ascorbate peroxidase and guaicol peroxidase increased at seedling stage while the levels of glutathione reductase and superoxide dismutase increased significantly at vegetative stage of both the genotypes. These results show that PRM-6107 is drought tolerant because the level of antioxidants as well as antioxidative enzymes is high in this genotype in seedling and vegetative stages. Also, the elevated levels of antioxidants and antioxidative enzymes at seedling stage show that plant start combating drought more strongly at seedling stage than at vegetative stage.

Stevia rebaudiana, belongs to the family of Asteraceae, is a perennial and medicinal shrub. It’s leaves dry powder widely used as a natural sweetener which has no calories but reported to be 50– 300 times sweetener as sweet as sugar, that are said to be having insulin balancing properties without any side effects. This research was first time conducted in Bangladesh where a quantitative analysis were performed for determining the major constituents of in vitro propagated Stevia rebaudiana plant leaves dry powder that was prepared through oven dry after sun dry. The analysis revealed the powder as mild acidic (PH 5.345). Total chlorophyll contents were found to be 0.845mg% where chlorophyll–a and -b were 0.088 and 0.761 mg% respectively. The major macro nutrients such as ash, crude fiber, total carbohydrate, total protein and fat were determined at the amount of 7.05, 10.5, 53.52, 13.13 and 3.55 gm% respectively where the micro nutrients like Iron (Fe), Sodium (Na), Potassium (K), Calcium (Ca), Magnesium (Mg), Phosphorus (P) and Chloride (Cl) were found at the amount of 34.2, 184.3, 2500, 534.43, 465.34, 304.7 and 49.6 mg% accordingly. Screening for secondary metabolites showed the presence of alkaloids, flavonoids, saponins and tannins as the amount of 2.83, 17.20, 6.69 and 5.84 mg% respectively in dry powder. These findings also have been compared with the other reported values on Stevia from different countries of the world. Int J Appl Sci Biotechnol, Vol 3(4): 721-726

The laboratory experiment was conducted at the laboratory of the Department of Entomology, Bangladesh Agricultural University to determine the effectiveness of polythene band, predatory ladybird beetles (available species found in Bangladesh viz. Coccinella transversalis (F.), Micraspis discolor (F.), Menochilus sexmaculatus (F.), Cyclonida sanguinea, Adalia bipunctata, Coccinella novemnotata and Illeis koebelei), four chemical insecticides and three botanical oils in controlling papaya mealybug, Paracoccus marginatus Williams and Granara de Willink. The chemical insecticides were Sevin 85 SP, Dimethoate 40 EC, Fipronil 50 EC, Deltamethrin 2.5 EC, and the botanical oils were Neem oil, Mahogany oil and Karanja oil. In the laboratory experiment, polythene banding failed to prevent the plant from the infestation of papaya mealybug. Seven commonly available species of ladybird beetles in Bangladesh did not provide any control to papaya mealybug. Among the chemical insecticides, Sevin 85 SP and Dimethoate 40 EC showed significant mortality of papaya mealybug. Deltamethrin 2.5 EC and Neem oil (2%) provided moderate control of the pest. The remaining insecticides and botanical oils were less effective to control papaya mealybug. Int J Appl Sci Biotechnol, Vol 3(4): 687-691

The experiment was conducted at the Spices Research Centre, Shibgonj, Bogra during rabi season, 2010-11and 2011-12 to identify the suitable pollinator attractant crops for increasing the vigilance of pollinators and higher seed settings and thereby increasing seed yield of onion. In 2010-11, the highest seed setting was recorded in onion + fennel (69.88%) which was statistically identical to Onion + coriander (67.45 %) and Onion + black cumin (64.15 %) while the highest seed setting was recorded in Onion + Fennel (73.70 %) which was identical to Onion + Dill (70.50%) and Onion + Coriander( 72.37%) during 2011-12. In 2010-11, the highest seed yield (865.5 kg/ha) was obtained from Onion + fennel which was identical to Onion + coriander (838.1 kg/ha) but in 2011-12, the highest seed yield (1165.34 kg/ha) was recorded from Onion + fennel which was identical to Onion + coriander (1064.59 kg/ha). In both the years, percent seed setting was lowest in Sole onion (55.93 % in 2010-11and 57.73% in 2011-12). Accordingly, the lowest seed yield was also recorded from Sole onion (623.3 kg/ha in 2010-11 and 685.44 kg/ha in 2011-12). Dill and Fennel was the better attractant crop for pollination while coriander acted as intermediate. Int J Appl Sci Biotechnol, Vol 3(4): 737-743

Published: December 2015

An efficient plant regeneration system from embryogenic callus of two elite indica rice (Oryza sativa spp. indica) varieties of Northeast India, Ketokijoha and Monoharsali is established. The effect of auxin, 2,4-dicholorophenoxy acetic acid (2,4-D) on callus induction was optimized. Friable, nodular and creamish-white embryogenic calli were induced from mature seeds on NB medium supplemented with 2.5 mg/l 2,4-D. Plants were regenerated from 40-50 days old embryogenic callus on NB medium containing 0.5 mg/l BAP (6-benzylaminopurine) and 0.25 mg/l ABA (abscisic acid). Regenerated plants with multiple tillers were rooted on half strength MS medium and rooted plants were acclimatized with 94% survival rate. Higher frequency of callus induction as well as plant regeneration was recorded in Ketokijoha as compared to Monoharsali. The calli of both the varieties were found amenable to Agrobacterium-mediated transformation as evident from strong GUS (β-glucuronidase) expression. The results may find wide application for genetic improvement for valuable traits these elite indica rice varieties of Northeast India. Int J Appl Sci Biotechnol, Vol 3(4): 680-686

The Milky Way appears to be a normal spiral galaxy that obeys scaling relations like the Tully–Fisher relation, the size–mass relation, and the disk maximality–surface brightness relation. The stellar disk is maximal, and the spiral arms are massive. The bumps and wiggles in the terminal velocity curve correspond to known spiral features (e.g., the Centaurus arm is a ∼50% overdensity). The rotation curve switches between positive and negative over scales of hundreds of parsecs. The rms amplitude

We note that NGC 3521 is a near twin to the Milky Way, having a similar luminosity, scale length, and rotation curve.
