Four different strategies of pulping and bleaching were carried out to develop alternative mechanistic ecoenvironmental friendly approaches and generated effluent was characterised. Strategy-I included Phanerochaete sp. fungal pretreatment followed by conventional bleaching, whereas in strategy-II, fungal pretreatment was followed by enzyme xylanase aided bleaching. Strategy-III also included x...

OBJECTIVE To determine the most effective and biodegradable dispersant of spilled oil in water surrounding two Persian Gulf provinces. METHODS This study compared the effects of three dispersants, Pars 1, Pars 2, and Gamlen OD4000 on removal of oil in two Persian Gulf provinces' water. Overall, 16 stations were selected. Using the Well method, the growth rate of isolated bacteria and fungi wa...

Conformal Killing vectors (CKVs) preserve the spacetime metric up to a factor. Homothetic vectors and Killing vectors are special cases of CKVs. Classification of some classes of spacetimes on the basis of CKVs give interesting results showing how homothetic and Killing vectors which form subsets of the set of CKVs can be recovered as a result of the above classification. ∗On leave from: Centre...

Computational tools for normal mode analysis, which are widely used in physics and materials science problems, are designed here in a single package called NMscatt (Normal Modes & scattering) that allows arbitrarily large systems to be handled. The package allows inelastic neutron and X-ray scattering observables to be calculated, allowing comparison with experimental data produced at large sca...

This study concerns the deployment of large numbers of container transporting vehicles on a network consisting of (dedicated) roads and logistic sites such as container terminals. Each site is managed autonomously by a site manager. The fleet of vehicles is deployed by a fleet manager. On request of the site managers, the fleet manager allocates vehicles to be hired by the site managers. Next, ...

Animals neither negotiate verbally nor conclude binding contracts, but nevertheless regularly exchange goods and services without overt coercion and manage to arrive at agreements over exchange rates. Biological market theory predicts that such exchange rates fluctuate according to the law of supply and demand. Previous studies showed that primates pay more when commodities become scarcer: subo...

OBJECTIVE This study aimed to determine if occupational exposure to whole-body vibration is associated with cervical intervertebral disc herniation among container truck drivers. METHODS We conducted a walk-through survey among container truck drivers and unexposed workers. We also measured the vibration hazard of the container truck over the driver's back and seat when the driver was loading...

The temperature profile of infectious laboratory waste being autoclaved was examined relative to the type of containers used in the process. A standardized waste load (1,750 +/- 4 g) placed in the container was evaluated by using a direct readout thermocouple. The sensor of the thermocouple was placed within an unused and outdated agar plate, centrally located about 5 cm from the bottom of the ...

Due to the increase in world-wide containerized cargo transport port authorities are facing considerable pressure to increase efficiency of existing facilities. Container vessels with 18, 000 TEUs (twenty-foot equivalent units) are expected soon to create high flow peaks at container terminals. In this paper we propose a new framework for managing intermodal container terminals, based on the mo...

The amount of container goods that is lost due to theft, piracy, accidents and damage is unfortunately increasing. Real time remote containers tracking and monitoring can help prevent losing track of container and goods, as well as provide actionable information in order to retrieve goods or minimize damage. Moreover, the ability to determine responsibility in case of damage or theft leads to r...
