What are the main objects of the seasoning of timber?
What are the advantages of using a steel tube rather than solid section steel?
Some of the advantages of using a steel tube rather than solid section steel are :- 1. Less Steel used so less cost. 2. Less Weight for a given design strength. 3. Less Weight for a given Length.

Global Positioning System (GPS) refers to the NAVSTAR Global Positioning System, a constellations of satellites developed by the United States Department of Defence. At first the GPS was made for military use only, but later made accessible to civilians as well. But recently, GPS is most widely used GNSS satellite constellation in the world.
Globalnaya Navigazionnaya Sputnikovaya Sistema (GLONASS) is an acronym which is translated from Russian, this means Global Navigation Satellite System. It is accessible for both military and civil use and also provides real time position and velocity determination.
The main difference between GPS & GLONASS is that, with GPS satellites use the same radio frequencies but have different codes for communication while GLONASS satellites have the same codes but use different frequencies, allowing satellites on the same orbital plane to communicate.

Generally hill profiles are irregular. So, the most efficient method for hill road is the prismoidal method (Simpson method). It based on the assumption that profile is parabolic between two sections. For use of this method, it is necessary that profile should be divided into odd number of section.Read more

For use of this method, it is necessary that profile should be divided into odd number of section. If the profile is divided in even number of section than apply prismoidal method till the second last section and apply the trapezoidal method in last section.

What are the advantages of running electrical cables through PVC conduits in the walls over running in the slab? Are there any problems which may come up in the future if we run electrical cables conduits in the slab?
The main advantage, from my point of view, is that it may so happen that we may want to demolish a wall in the house for what so ever reason, but we can't dismantle or harm the slab since its a structural member. The second reason is that a slab may run continuously throughout the structure; hence wRead more
The main advantage, from my point of view, is that it may so happen that we may want to demolish a wall in the house for what so ever reason, but we can’t dismantle or harm the slab since its a structural member.
The second reason is that a slab may run continuously throughout the structure; hence we can lay straight cables throughout the structure and provide connection where ever required, but in case of walls, we may not find this convenient.
Also, if the walls are periphery or exterior walls, which may be directly exposed to rains, then it may cause Earthing issues.
See lessWhat is contour farming?In which type of soil contour farming is suitable?
Contour farming is an agricultural practice where steps are cut out on a sloped field so as to provide steps of flat land (same contour) for cultivation. The potential benefits are a check on erosion, better rainfall usage, more infiltration, and reduction in the need for irrigation. It is feasibleRead more

It is feasible on all slopy regions to accept on those with highly erodible soils and soils that allow little infiltration.

Eidograph has the simple function of copying maps and plots to a different scale. It works on the same principles as a pantograph with the only difference of mechanism.

Eidograph has the simple function of copying maps and plots to a different scale. It works on the same principles as a pantograph with the only difference of mechanism. The pantograph uses linkages arranged in a parallelogram while the eidograph might have either a string and pulley system or parallelogram linkages.
There are two pens attached. If you move the primary pin on the map, after setting a desired scale, the secondary pen draws the same map scaled to the scale you set.
