The Marine Stewardship Council (MSC) certification is the market-leading seafood eco-label, including in deep-sea fisheries, about which there are growing concerns around sustainability. Greenland economically dependent on for halibut (Reinhardtius hippoglossoides). offshore fishery, employs demersal trawls (800–1,400 m), obtained MSC 2017. This provides an opportunity to critically assess gove...

Harvesting rain-fed chickpeas (Cicer arietinum L.) from fallow fields in developing countries is currently a manual process performed by laborers in a tedious manner at a low level of efficiency. A tractor-pulled harvester was built in which a chain conveyor transfer harvested material. A tractor-mounted harvester was then redesigned, which incorporated a modified stripper header to detach pods...

The aim of this paper is to describe the geometry of conformal structures in Lorentzian signature, which admit a lightlike conformal Killing vector field whose corresponding adjoint tractor acts as complex structure on the standard tractor bundle of conformal geometry. Key to the treatment of this problem is CR-geometry and the Fefferman construction. In fact, we will consider here partially in...

In this paper, we consider active trailer steering control as a means to improve the maneuverability of (long) truck–trailer combinations during cornering. Hereto, we formulate the problem of reducing the so-called swept path width during cornering and that of eliminating unsafe tail swing of the trailer as a tracking control problem. We present a kinematic tractor–trailer model including off-a...

the directional response and roll stability characteristics of a partly filled tractor semi-trailer vehicle, with cylindrical tank, are investigated in various maneuvers. the dynamic interaction of liquid cargo with the tractor semi-trailer vehicle is also evaluated by integrating a dynamic slosh model of the partly filled tank with five-degrees-of-freedom of a tractor semi-trailer tank model. ...

in this paper a survey to determine the spring and damper settings of itm285 tractor’s cabin which ensured optimal ride comfort of tractor operator was conducted. analysis has been done in terms of root mean square acceleration response (rmsar) in one-third-octave band and international standard organization (iso). optimization was performed using particle swarm optimization (pso) method on a 2...

Methods The study included sixty patients aged from 39 to 79 years presenting for CABS who were randomized to control or cell saver groups. We investigated blood parameters before and after surgery, ejection fraction, postoperative drainage, intraoperative parameters such as coronary artery bypass grafting type, number of graft, extracorporeal circulation and aortic cross clamping duration as w...
