Effect of Dynamic Platform Lateral Step-Up versus Stable Platform Lateral Step-Up Weight Bearing Exercise in Hip Abductor Strengthening on Healthy Male Volunteers - Randomized Clinical Trial

Objective & Background: To determine the effect of the dynamic platform lateral step-up and stable platform lateral step-up weight bearing standing exercise in strengthening of hip abductor. Many researchers have reported that strengthening of hip muscles as important component especially hip abductors in lower extremity rehabilitation program. Study Design: Single blinded randomized comparative clinical trial. Methodology: Sixty five healthy college going male subjects (Age group of 18 – 24 years) volunteered for this study. They were randomly assigned to one of the 2 groups. One group received the dynamic platform lateral step-up and the other received stable platform lateral step-up weight bearing standing exercise. The strength measurements were recorded using hand held dynamometer. Results: The results indicate that both groups had a positive effect on the outcome measures. The strength of hip abductors in dynamic platform group improved from a mean value (SD) of 19.47(3.59) to 26.93(3.19) and in stable platform group from 19.07(2.32) to 22.67(2.46). Significant difference is also observed between the two groups at p value .05. Conclusion: The study shows that dynamic platform lateral step-up exercise is more beneficial than stable platform lateral step-up weight bearing standing exercise in improving hip abductor muscle strength

Investigating congestion mitigation scenarios to reduce truck turn time at Port of Montreal using Discrete Event Simulation

Container ports are facing the growing problem of congestion due to the high volume of container trucks entering the terminal. Globalization, growth of trade and increasing consumer demand have further added to this complexity which has resulted in increased greenhouse gas emissions at the ports. Several measures are being undertaken by the ports to reduce this problem and improve port sustainability. Examples of these measures are implementing advanced technology equipment, implementing extended gate hours, changing the arrival patterns of trucks, and implementing variable gate lane policies. The objective of the thesis is to develop a discrete event simulation (DES) model to investigate the congestion mitigation scenarios to improve terminal productivity and reduce truck turn times at the Port of Montreal. A case study with the Montreal Port Authority is conducted. The results of our simulation study yield upgrade of technology at the terminals as the best solution followed by managing the arrival patterns, changing gate lanes and extended gating hours. The proposed work is novel and one of the very few to be conducted in the context of Port of Montreal. The generated results can be used by decision makers at Port of Montreal in developing strategies to mitigate congestion and reduce truck turn times at terminals

Improved strategy for large scale isolation of sialylglycopeptide (SGP) from egg yolk powder

Chicken egg yolk is an easily available source for the isolation of sialylglycopeptides (SGP) carrying homogenous biantennary N-glycans. This approach has gained much attention in the last decade since these SGPs can easily be used for the semi-synthesis of glycoconjugates circumventing laborious full-synthetic methodologies. Here we report an optimised, significantly shorter (one day instead of five) and environmentally friendly procedure for the mg scale isolation of SGP using commercially available egg yolk powder. A single chromatographic step following chloroform/methanol precipitation of proteins and lipids yielded desired approximately 200 mg SGP from 250 g egg yolk powder within a day. •Environmentally friendly procedure for isolation of sialylglycopeptide from Egg yolk powder. •Reduced the protocol from five days down to one

Comparison of incidences and indications of multi primary caesarean with primi caesarean mothers in a tertiary care teaching hospital

Background: The incidences and indications of caesarean sections between the primary caesarean multies and caesarean primies were comparable in respect of their demographical and clinical variables of mothers and their foetal outcomes. Aim and objective of the study was to analyze the incidences and indications of primary caesarean multies and caesarean primies. To compare the incidences and indications of mothers between the primary caesarean multies and caesarean primies. To compare the demographic and clinical profiles of the mothers and babies.Methods: During January to June 2016 total of 3583 deliveries were conducted in Tiruneleli Medical College Hospital, Tamil Nadu, India. Among them 89 and 1168 were primary caesarean multies and caesarean primies respectively. They had been compared according to the objectives.Results: The caesarean incidences were 62.5% among the primies and 4.8% among the multies as Primary. The primary caesarean incidences among the multies were statistically significantly lesser in the 15-24 ages than the primi (P0.05). After 30 years of age, the incidences were statistically significantly increased among the multies (P0.05). The indications of Foetal distress, Severe Oligo hydration and others did not show any statistically significantly difference between the groups (P>0.05). Mal presentation and Ante Partum hemorrhage were significantly more among the multies than primies (p<0.05) and Failed indication and CPD were the significantly lesser indication than the primies (P<0.05).Conclusions: Without reducing the caesarean section rate in primi we cannot bring down the overall caesarean rate of delivery

Prospects of biodrainage to mitigate problems of waterlogging and soil salinity in context of India - A review

Major parts of agricultural lands in arid and semi-arid regions of India are affected by soil salinity and waterlogging in canal command area and outside. Waterlogging is caused by a rising water table and poor drainage conditions.&nbsp; Stress due to waterlogging and salinity are serious to plants in all stages from seed germination to active growth and maturity. Unmanaged affected agricultural lands turn into low productive marshlands in the long run. Physical provision of surface or sub-surface drainage structures can rescue in such a situation. Yet, high skill and investment are required in the installation and maintenance of such structures. Alternatively, biodrainage method has been evolved as an effective method recently world over. In biodrainage, plants are raised over a larger area, which can transpire and remove an enormous amount of water from the soil. Plants having adequate adaptive traits and tolerance mechanisms are desirable to mitigate waterlogging and salinity. Biodrainage is suitable in rainfed and irrigated conditions. Planting of right plant species in optimum population and geometry decides the efficiency of biodrainage. Further, combining biodrainage with the conventional drainage can improve land and water productivity. Eucalyptus is the most suitable tree species for biodrainage as it has well performed in versatile environments. It possesses appreciable tolerance to salinity, sodicity and waterlogged conditions of the soil.&nbsp; Fast-growing with a straight trunk, deep rooting ability, low shading effect and high transpiration capacity are promising characteristics of this tree.&nbsp; Prominent woody species like Acacia nilotica, Dalbergia sissoo, Hardwickia binata can also be grown for high profit
