Abstract: Eighteen healthy mongrel dogs of sexes, varying ages (16.50 ± 0.22 months) and weights (19.83 ± 0.16 kg) were used in this study. The experiment was conducted in the Department of Surgery and Obstetrics, Faculty of Animal Husbandry and Veterinary Sciences, Sindh Agriculture University, Tandojam.A total of 18 dogs (male and female) were randomly divided into three groups placing 6 animals in each i.e., group-A (Vicryl 3/0 suture material), B (Dexon 3/0 suture material) and C (stapler). Physically healthy animals were used in this study in order to achieve the required results. Xylazine (9.91 ± 0.08 mg/dog) and thiopental Sodium (198.33 ± 1.05 mg/dog) was administered intramuscularly in all groups. The anaesthetized animals were placed on the dorsal recumbancy on surgical table in order to perform surgical procedure. The caudal ventral midline incision of 5 cm was made in all dogs to exteriorized the colon. One incision of 5 cm was given on colon and bleeding was controlled by artery forceps. Colon incision was closed with Vicryl (3/0) in group-A, Dixon (3/0) in group-B and intestinal stapling materials in dogs of group-C. The peritoneum in each dog was sutured with chromic catgut by simple interrupted suture technique, the linea alba was sutured with chromic catgut by simple continuous suture technique, sub-cutaneous layer was apposed with sub-cuticular suture technique using 3/0 chromic catgut. Skin was closed with simple interrupted suture pattern using silk 2/0 suture material in dogs.The total duration of anesthesia required was 328.33 ± 1.17, 330.00 ± 1.39 and 313.83 ± 2.52 minutes for closure of colon closed with Vicryl, Dexon and Stapling material respectively. The mean number of total stitches for colon closure with Vicryl, Dexon and stapling material was 15 ±0.57. 17.00 ± 0.36 and 6.66 ± 0.21 respectively. Though the partial development of mucosal folds can be seen on day 10 of post-surgery whereas fully development except lamina epithelia on day 20. It is concluded that Vicryl suture material showed the superiority in terms of better apposition of the sutured tissues and better healing and lesser complications like minimal adhesions between sutured site and other structures applied with double layer appositional suture technique for the closure of colon in dogs. This study also reveals that all suture materials were not completely free from complications but staple technique showed quicker application and lesser number of staples was required as compare to Vicryl and Dexon suture stitches and duration..

Abstract: Crop yield is the resultant product of components character which is not under the control of any single gene, therefore it is necessary for plant breeder to know the relationship between two traits. The present research was conducted to calculate the correlation and regression for yield and yield contributing traits in mutant population of bread wheat. The experiment was conducted at Nuclear Institute of Agriculture (NIA), Tandojam, during rabi season 2015-2016, in split plot design with three replications. Material under study was two wheat varieties (T.D-1 and ESW-9525). These two wheat varieties were evaluated along with control for yield and yield associated traits under normal field conditions. Mean square showed that there were significant differences between wheat varieties for days to 75% heading, days to 75% maturity, plant height (cm), spikelets spike-1, grains spike-1, 1000 grain weight (g), biological yield plant-1 (g), harvest index (%), spike length (cm) and grain yield plant-1 (g). Number of grains spike-1 showed positive and highly significant correlation with spike length, spikelets spike-1, 1000 grain weight and biological yield of plant-1. Significant and positive with days to 75% maturity and harvest index. However, negative correlation was found with height of plant and non-significant but negative with the trait of days to 75% heading. Grain yield plant-1 showed highly positive highly significant association with grains spike-1, number of spikelets spike-1, length of spike, harvest index and biological yield plant-1 and negative with plant height. Approximately 85.9%, 65.2%, 59% and 24.3% variation in grain yield plant-1 is due to grains spike-1, biological yield plant-1, harvest seed index and height of plant, respectively. This shows that taller plants produce lesser grain yield.

Abstract: Farm friendly and fast growing trees are the sustainable, cheaper and efficient source of carbon sequestration and carbon stock, however, their carbon sequestration potential vary among tree species depending upon several factors. This study was conducted to determine the carbon sequestration potential and carbon storage difference among different tree species at early stage. Second objective of this study was to observe the effects of trees on the physico-chemical properties of soils. Seedlings of fifteen widely planted farm trees species were planted under same set of climatic and soil conditions. Employing tree biomass after two year of planting (2014-2016), carbon stocks and carbon sequestration rates were calculated. Soil samples were collected under each tree species at two depths: 0-15cm and 16-30 cm, to determine the physico-chemical properties of soils such as pH, EC, N, P, K, C and organic matter (O.M.). It was found that Populus deltoides contained the highest carbon stocks (7.21 ± 1.31 kg C) and sequestered the CO2 at the highest rate of 13.21 ± 0.84 kg C/year as compared to all other fourteen tree species. O.M. (%) and Carbon (mg/kg) were also the highest in the soils under P. deltoides (2.29 ± 0.42 and 3.8 ± 0.2 respectively) as compared to and all other tree species. Nitrogen contents (%) were found the maximum in the soils under D. sissoo (0.063 ± 0.04) > Acacia nilotica (0.058 ± 0.008) and Albizia lebbeck (similar to Acacia nilotica). Such information enhances our capacity to better predict the carbon sequestration potential and carbon stock in different trees.

Abstract: Dysgraphia, a learning disability associated with writing skills, hinders students to put their thought on paper and write correctly. Writing problems hit students most frequently that one third students become failed to acquire writing skill. Different IT based assistance solutions available for dysgraphia students but most of them are accommodations based or provides writing alternatives rather than developing writing skills of a dysgraphia student. Handwriting is an essential skill for academic life and developed handwriting skill helps student to protect their self-esteem and build student’s confidence to participate in other activities during class. Most of available writing assistance solutions do not provide interesting ways to acquire writing skills. To handle this problem, augmented reality (AR) based dysgraphia assistance solution has presented in this work. This study utilized AR to develop dysgraphia student’s interest in writing and used it to assist in writing activity by providing help in spellings. AR based dysgraphia assistance writing environment (AR-DAWE) modal use Google cloud API of speech-to-text and addressed one of the important issues of dysgraphia student that is associated with spelling mistakes.
