Modification of Reduction Clearing Process of Polyester Blend Cotton Knitted Fabric Dyeing[ ]


Reduction clearing is a very well established process in case of polyester and polyester blend cotton fabric dyeing. Reduction clearing is done for the removal of unfixed dyes and auxiliaries from the fabric surface being a prerequisite of quality assurance and the ease of subsequent processes. Usually in case of two bath polyester blend cotton dyeing, prior to polyester part dyeing pretreatment (followed by scouring, bleaching and enzyme wash wash) is done first. Then polyester part is dyed followed by reduction clearing. Finally cotton part is dyed. But in this study few modifications of reduction clearing process have been scrutinized combining the scouring, bleaching and reduction clearing process simultaneously and incurring the sequential inter change between polyester part dyeing and pretreatment (scouring, bleaching, enzyme wash) with and without reduction clearing process separately. Accomplishing the experiments, the fabric samples were characterized by wash fastness, rubbing fastness, perspiration fastness, light fastness, surface smoothness and compared with aforementioned process. The modified process was also investigated in terms of water consumption, power consumption, steam consumption and total process time. The results revealed very good fastness properties and salient economic efficiency reducing all utility consumption and process time.

Systems Analysis of Commercial Motorcycle Service Safety Problem in Nigeria[ ]


The use of motorcycles for carrying passengers for a fee (commercial motorcycles) has been suffering from serious safety challenges over the years in Nigeria. Policy measures developed to address this problem have not been very successful. This paper looks at the safety problem and presents an illustration of how a model (a system dynamics model) of the safety problem was formalised. The results obtained from model runs reveal how the model developed offers an opportunity for policy makers and stakeholders to better understand the structure and the dynamics of the safety problem. It also indicates that something can be done to improve safe driving behaviour of the drivers. Particularly, it points out that a mix of measures including improved enforcement of law is one main way by which driver behaviour can be improved. But it also warns that increasing the number of enforcement officers does not improve enforcement in a corrupt environment.

A Novel Closed Loop Topology for Coupled Inductor Based DC-DC Converter[ ]


In the closed loop topology for a coupled inductor based DC-DC converter we have a tendency to introduce a voltage multiplier converter with coupled inductance for high gain output charging the battery of a feedback loop for DC machine drive for variable input voltage. The dual switches structure is helpful to scale back the voltage stress and current stress of the switch. Additionally, 2 multiplier capacitors are charged throughout the switch-on period and switch-off period, which will increase the voltage conversion gain. Meanwhile, the energy stored within the inductance is recycled with the clamped capacitors. Thus, 2 main power switches with low on-resistance and low current stress are available. This project illustrates the operation principle of the designed DC-DC converter, the output voltage of the high step-up converter is maintained constant by automatic variation of the duty ratio with feedback as PI Controller. The constant output voltage for varying input DC voltage is represented graphically using MATLAB simulation for various industrial applications.

Transient Numerical Models for Predicting the Performance of Encapsulated PCM Under Varying Ambient Temperatures for Cooling Application[ ]


This paper is aimed at presenting a single phase transient heat conduction model that mimics the effects of phase change present in paraffin wax under varying ambient temperatures for cooling application. The low energy encapsulated PCM-paraffin wax with initial temperature at 20oC, is modelled and numerically studied using the explicit finite difference method (FDM) and the effective heat capacity method (EHC). Numerical results obtained from Matlab showed that the melting temperature of the modelled paraffin varies but falls within the range of 23 – 26oC.The combination of the FDM and EHC numerical methods prove suitable for simplification and solving moving boundary phase change problems. Numerical results showed that encapsulating paraffin wax with high density polyethylene shells and exposing these capsules to ambient temperature conditions is capable of causing significant drop in ambient temperatures from 22 – 31.5oC to 14.2 – 20.3oC representing temperature depressions of 7.84 – 11.24oC.

An Efficient and Feasible Solar Irrigation System In-cluding AC Mini-Grid Designed for Bangladeshi Agri-culture[ ]


The idea of introducing a mini-grid along with irrigation is originated considering the huge load shedding of a particular area. People of that area remain without electricity for approximately 6-8 hours in a day. A small survey was also conducted on 50 houses of Teghoria, Poradaho, Mirpur, Kushtia, Bangladesh and data were collected about their electricity demand during the time of load shedding every day. The mini-grid would be powered by the extra energy coming from the irrigation panel. This was done simply by changing the run time of the motor in an efficient way. The run time of the motor varies in different seasons. HOMER software was used to calculate the cost analysis of the proposed model for irrigation along with ac mini-grid. The proposed model provides two welfares. The first one is that the rural farmers can get water for irrigation with a lower installment which is shown in the paper. The second one is that the demand of electricity of rural people during load shedding can also be fulfilled from the ac mini-grid. Therefore, the overall cost can be minimized and the new irrigation system becomes more feasible for rural farmers as well as for the owners.

Hydraulic Valve Operating System For Two Wheeler[ ]


Hydraulic Actuation Of Valve (HAV) is a mechanism to replace the mechanical actuation of valve in the 4 stroke IC engine presently in use. To overcome the disadvantages of the present system i.e. engine noise, oil leak at interfaces etc, hydraulic actuation mechanism is used, which eliminates some moving parts of 4 strokes engine like rocker arm, push rod tappet arrangement, cam chain, as well as some stationary parts like chain tensioner and, tension adjuster, thereby reducing the cost of production as well as weight of the engine and making the engine more compact. This mechanism has more advantages for two wheeler engine, especially for the engines having two spark plug for single cylinder as it reduces the engine weight. Due to less number of parts used. Heat transfer between the engine and atmosphere will be at a uniform rate at the cylinder block and cylinder head surface. Due to elimination of some moving parts of the engine, casting of cylinder head and cylinder block is easier.

Effective disruption method of shrimp hepatopancreatic tissues to release hyalauronidase[ ]


Tissues of hepatopancreas of shrimps were homogenized Potter-Elvehjem homogenizer at 15 passes per min in 20 mM Sodium acetate buffer of pH 5.5 and temperature 4oC. Effectiveness of the homogenization was estimated using total protein released and the hyalauronidase activity of the homogenate. Hyaluronidase optimally released at an operating speed of 3000 rpm for 10 min. Operating speed beyond 3000 rpm at given time reduced the activity of hyaluronidase or increase in exposure time beyond 10 min at 3000 rpm caused sheer damage to the enzyme. Pestle speed beyond 3000 rpm did not improve protein yield, but adversly affected the hyalauronidase activ-ity.
