Evaluation of Matured Larval Weight and Larval Duration of New Breeding Lines of Bombyx mori L

We planned to conduct this study with the main aim to develop bivoltine breeds for our tropical climatic conditions by using silkworm breeds with known genetic backgrounds (KA, NB18 and PM) in various hybrid combinations and incorporating them over generations, followed by backcrossing and adequate selection of different generations with the objective of profitability and productivity. The isolated Bivoltin lines (R1 and R2) were reared with their parental races at different times of the year to evaluate their stability in the expression of commercial traits. For the present breeding program, the purebred Bivoltine Kalimpong-A (KA), which spin white oval cocoons, New Bivoltine18 (NB18) white cocoons with rotating dumbbells and Multivoltine Pure Mysore (PM), the yellow pointed cocoons of the mulberry silkworm Bombyx mori L., Selected. One-way and three-way crosses were made using the above three breeds. The first single cross comprised KA females and PM males. The second unique cross comprised NB18 females and PM males. Selection was performed at the egg, larva, pupal, and cocoon stages over the course to determine the desired traits. The offspring of F from the respective crosses were backcrossed with their respective bivoltine males to improve commercial traits. Heterosis in the F1 generations of crosses, including NB18 and PM, was determined by the mean score of the parents (MPV) and the best score of the parents (BPV). A significant test for heterosis was performed using a standard ANOVA table. Based on the results of our study, it was found that the performance of the characters, viz. The weight of mature larvae and the duration of the larvae over generations do not simply increase or decrease regularly, but fluctuate irregularly. The reason for this variation may be due to random genetic drift, sampling errors in estimating generational means, selection pressures, and environmental factors. Therefore, inbreeding variations due to random drift and sampling errors could be reduced by increasing the number sampled and selected.

Comparing inhibitory effect some of probiotics and antibiotics against pathogenic bacteria isolated from injuries of military operations

This study aimed to isolate the antibiotics-resistant bacteria causing burns and wounds infections in military operation patients, and to compare the inhibitory efficacy of probiotics with the most common effective antibiotics. For this purpose, collected a total of 52 male patients of ages from 18 to 55 years suffering of wounds and burns infection from Military Muthanna Hospital form the period September 2019 to January 2020. Distributed between 34 of the samples were collected from wounds and 18 from burns. 27 (51.92%) from the wounds and 14 (26.92%) from the burns gave positive results for bacterial growth. A total of 61 bacterial isolates, 40 from wounds and 21 from burns, were obtained after culturing on MacConkey agar and blood agar and incubating at 37ºC for 24h. The isolates were identified by cultural, microscopic and biochemical tests and found to belong to both Gram positive and Gram-negative bacteria .The susceptibility test was performed by subjected each of the wound and burn isolates to four most common antibiotics to each isolate bacterium. Results showed that majority of the isolates were highly sensitive to Ciprofloxacin and Gentamicin. 8 of the highly antibiotic-resistant isolates were selected for treatment by two bacterial probiotics; Lactobacillus casei and L. paracasei Cultivated independently, in MRS broth (de Man, Rogosa and Sharpe broth) medium. The fermentation products were then concentrated (50, 25, and12.5) ml and the inhibitory activity of the eight most antibiotic-resistant isolates used was tested. Experiment was repeated three times and analysed with SPSS software. ANOVA Table with Tukey's Multiple Comparison Test. Results showed that despite the three-fold concentrated filtrates of both probiotics exerted good inhibitory activity against the pathogenic isolates, but L. casei filtrate was highly effective than that of L. paracasei. Moreover, L. casei filtrate was even competitor to Ciprofloxacin and Gentamicin.

Study on the Relationship Between Literacy and Dowry Mortality in Different Indian States

Background: Dowry death is old wicked tradition. Death by burning of married women was reported to be 452 for the year 1985, 478 for the year 1986 and 300 for the first initial six months of 1987, of women belonging to age16 to 30 years. [1, 2]. 1, 319cases were also reported nationwide in 1986 [1, 3].

Analysis of Variance

Analysis of variance is introduced using a worked analysis of some data collected by Charles Darwin on inbreeding depression in experimental maize plants. ANOVA is used to compare the heights of a group of cross-pollinated plants with a group of self-fertilized seedlings. The least squares process is explained, including the calculation of sums of squares and variances and the calculation of F-ratios. The organization of the results of a linear model into an ANOVA table is explained. The R code necessary to perform the analysis is worked through and explained in terms of the underlying statistical concepts, and the interpretation of the R output is demonstrated.

The Effect of Students’ Metacognition and Digital Literacy in Virtual Lectures during the Covid-19 Pandemic on Achievement in the “Methods and Strategies on Physics Learning” Course

This study aims to determine the effect of students’ metacognition and digital literacy skills on virtual lectures in the COVID-19 pandemic on achievement in the “Methods and Strategy on Physic Learning (MSPL)” course. The data was collected using a survey method which involved all 42 physics education students. The data analysis was carried out in two stages, namely the categorization stage and the correlation stage. Based on the data and analysis, it is known that the metacognition skill of physics education students is dominated by the “high” category with 40.47%, followed by the “medium” category at 35.71%, and the remaining 23.82% are at “low” category. As for the digital literacy, the variable is not much different from the metacognition skill, which is dominated by students with high category digital literacy skills at 42.85%, “moderate” category at 33.33%, and the rest 23.82% are at “low” category. Likewise, in the variable conceptualization of the concept of physics and physics learning strategies, physics students who are in the “high” category is more dominant than the “medium” and “low” categories, which are 33.33% and 28.58%, respectively. Based on the ANOVA table, it is known that the value of sig. 0,000, which is less than (<) 0.05. It can be said that X1 (metacognition) and X2 (digital literacy) simultaneously affect the Y variable (mastery of the MSPL concept). This is also reinforced by the calculated F value of 313.111> F table 3.22. It means that the two variables X1 and X2, simultaneously affect the Y variable (mastery of the MSPL concept).
