# Basic Geography/Rural

Rural areas generally have low populations and consist of isolated, expansive land, sometimes referred to as "the countryside". The term "rural" has various definitions.
# Basic Geography/Tourism

We know why we tour as tourists. You know why you may choose some parts of the globe over others by reasons such as family, cheap prices and activities- but do you specifically know why we tour?
Tourism varies a number of ways: time, number of tourists, and different reasons being just some. For example, you may spend 2 weeks in Borth which has thousands of tourists, or you may tour in the Amazon for a month where there are little tourists and for the purpose of ecotourism.
Many people look for cheaper places to tour. This means more money for the cheaper resorts, that tend to be Mass Tourism destinations and a big company.
Tourism can have positive and negative effects: money, jobs and a good recognition are common positives that tourism brings. However, Global warming, pollution and destruction of habitat are all negatives people are concerned about. Solutions are being carried out to make tourism more eco-friendly. Eco-tourism helps local communities, wildlife and produces much less pollution than mass tourism. But are the general public willing to tour in eco-tourist destinations?
# Basic Geography/Urban

Urban areas have high population densities, many buildings, and can encompass cities and towns. As with "rural", the term "urban" has various definitions.
# Basic Geology/Crust

The crust is the outer hard layer of the planet. The crust is a part of the lithosphere. On Earth, the crust is under the troposphere and above the ocean. It is important to remember that not every geological sphere has a crust. The crust on Earth is being created through a process called Continental Drift, but on the moon it is not being made. The crust has two different parts. One is the continental, and the other is oceanic. The continental crust is thicker, and the oceanic crust is thinner. Thicknesses of the crust can be anywhere from 5-70 km.
# Basic Geology/Glossary

This is an incomplete list of geological terminology with brief explanations of each concept.
* Andesite: Viscous lava erupted from a volcano above a subduction zone.
* Igneous Rock: A rock produced by the crystallization of magma.
* Geology: The study of Earth's physical structure and the processes that act on it.
* Lahar: River of mud, ash, and water.
* Metamorphic Rock: A rock that has experienced intense temperature and/or pressure after its formation and has changed its composition and/or texture.
* Mineral: A naturally occurring solid inorganic substance with a distinct crystal structure.
* Pahoehoe: Lava with an undulating surface, may have a ropey appearance.
* Rift Valley: A gap between the continental crust marked by volcanism; rift valleys may eventually develop into oceans, seas, etc.
* Rock: A natural material composed of minerals.
* Sedimentary Rock: A rock that has been formed by the lithification of sediment but has not been metamorphosed.
* Subduction zone: Area where plates meet, and one slides beneath the other.
* Texture: The physical appearance of a rock.

# Astrodynamics

This book is going to serve as an introduction to the field of astrodynamics, especially from a practical, engineering perspective. We will focus our attention on man-made satellites, and the dynamics of orbiting such satellites around the earth, the moon, and other "local" objects. We will look at practical applications, such as earth-orbits, lunar and inter-planetary trajectories, ballistic missiles, and interstellar escape trajectories.

## Service outside the GM service schedule

If the service history of the vehicle is unknown or if you like to give your van that extra care you can do maintenance outside the GM service schedule.

### Under the doghouse

* Change spark plugs, wires, cap, rotor and coil. Use dielectric grease on both ends of the ignition wires, inside the cap on the button and the coil wires - both ends. To protect the wires you could route them through wire looms.
* Change PCV valve.
* Check vacuum lines and elbows.
* Check the condition of the rear intake to head gasket.
* When you attach the splash guards, use new plug in holders.
* Clean the throttle body
* Check to make sure that all of the bolts are tight including the distributor, the back of the alternator, and everything around the throttle body.

### Under the bonnet

* Change air filter.
* Change the EGR gasket to a universal GM clean screen EGR valve gasket

## Service Parts Identification

The "SERVICE PARTS IDENTIFICATION" is a sticker located either in the glove compartment or at the rear of the passenger door. It specifies the setup the car had when leaving the factory. It contains numerous three letter aphanumeric codes called RPO codes. To understand what they represent you can check here: RPO Codes.com
# Astro and Safari Maintenance and Repair/Interior
## Front Door Panels
### Removal
#### Tools

* T30 Torx Screwdriver.
* Flat Head Screwdriver.
* Phillips Head Screw Driver.
* Prying Device (Flat head Screw Driver or pry bar).

#### Description

Disable the anti-theft on applicable models then detach the Negative wire from the battery to prevent the Airbag from deploying. Locate the three screws on the door handle. The Handle has round caps that need to be removed. Use the flat head to remove them; then the T30 Torx to remove the handle from the door. The Phillips head screw is located a little forward. You may have to open the door to see it. Remove the small panel behind the door handle. After this is removed; the panel with the door locks and window buttons attached are removable. Detach all the cables behind this unit. From the bottom of the door insert your prying device gently to avoid damaging finish. Feel for the Locking caps at the bottom only middle clips should pop out when bottom is pulled, When near one pry it away from the door. When you release one you should have room to remove the rest of the bottom with your hands. After the panel is detached at the bottom Push the panel upwards then to detach the top ones and the mirror panel will detach (It is held in with a white peg as well if you wish to remove it pull it after the door panel is off). If the panel is still attached after lifting up pull to the outer side of the car. Passenger side pull to right driver pull to left. There is a sideways clip as well as a upwards clip. Sometimes pulling up unlatches both. With the panel now removed you can gather all the white pegs out of the door and place them back inside the panel in the appropriate place so that the panel can go back on.

### Installation

To install reverse the steps. Be sure the top lip is placed over the window ledge. Clip in all the white pegs (Peak behind Panel).

# Astro and Safari Maintenance and Repair/Troubleshooting
## Body Leaks
### Rear Door - Hatch Leaking Water every time it rains, or snow melts

Sometimes this problem is encountered because water collects at the bottom of the van. You can run silicone under the plastic panel and along the border of the carpet. Make sure you run it edge to edge not leaving any gaps. Some prefer to Drill a whole into the bottom of the van and use the silicone to guide the water through the hole. If you choose this method place a rubber gasket or some other form of sealant in the hole so you do not end up rusting out your floor.

## Locks
### When I press the automatic locks the tab moves slightly but not all the way up. Door Remains locked.

The problem is either a weak actuator or interference to the movement, or possibly bad power feed to the actuator. In any case, you will probably have to remove the door panel to find the problem.

# C++ Programming/Programming Languages/C++/Code/Keywords
### ISO C++ keywords

The C++98 standard recognized the following keywords:
| and and_eq asm auto bitand bitor bool break case catch char class compl const const_cast continue default delete do | double dynamic_cast else enum explicit export extern false float for friend goto if inline int long mutable namespace new | not not_eq operator or or_eq private protected public register reinterpret_cast return short signed sizeof static static_cast struct switch template | this throw true try typedef typeid typename union unsigned using virtual void volatile wchar_t while xor xor_eq |
Specific compilers may (in a non-standard compliant mode) also treat some other words as keywords, including cdecl, far, fortran, huge, interrupt, near, pascal, typeof. Old compilers may recognize the overload keyword, an anachronism that has been removed from the language.
The current revision of C++, known as C++11, added some keywords:
| alignas alignof char16_t | char32_t constexpr decltype | noexcept nullptr | static_assert thread_local |
C++11 also added two special words which act like keywords in some contexts, but can be used as ordinary identifiers most of the time:
* final
* override
It would be bad practice to use these as identifiers when writing new code.
The C++98 keywords auto, default, delete and using have additional or changed uses in C++11.
Some old C++98 compilers may not recognize some or all of the following keywords:
| and and_eq bitand bitor bool catch compl const_cast | dynamic_cast explicit export false mutable namespace not not_eq | or or_eq reinterpret_cast static_cast template throw true try | typeid typename using wchar_t xor xor_eq |

### C++ reserved identifiers

Some "nonstandard" identifiers are reserved for distinct uses, to avoid conflicts on the naming of identifiers by vendors, library creators and users in general.
Reserved identifiers include keywords with two consecutive underscores (__), all that start with an underscore followed by an uppercase letter and some other categories of reserved identifiers carried over from the C library specification.
A list of C reserved identifiers can be found at the Internet Wayback Machine archived page: http://web.archive.org/web/20040209031039/http://oakroadsystems.com/tech/c-predef.htm#ReservedIdentifiers

# Castles of England/East Riding of Yorkshire

There are four castles of note in the East Riding of Yorkshire.
| Name | Type | Date | Condition | Ownership / Access | Notes (Key) |
| Flamborough Castle | Fortified Manor House | 130114th century | Fragmentary ruins | Private | Building At Risk. |

### Flamborough Castle

Flamborough Castle is a ruined a medieval fortified manor house. It is located in Flamborough a village in the East Riding of Yorkshire on the prominent coastal feature of Flamborough Head.

### Paull Holme Tower

Paull Holme Tower is a late-medieval period fortified tower. It is part of a rectangular, moated enclosure near the village of Paull dating from the beginning of the 15th century. The tower is three storeys high, each floor having a single chamber, the whole protected by a portcullis. There has been debate as to the purpose of the site - in part the fortification resembles the more northern pele towers, although alternatively the tower may have been built to give luxury accommodation overlooking the River Humber that runs nearby, similar to some properties built near King's Lynn.

### Skipsea Castle

Skipsea Castle is a Norman Motte and Bailey castle located south of Bridlington. All that remains visible today are the earthworks, having been destroyed by the order of Henry III. The castle was built around 1086, in the years following the Norman Conquest by Drogo de la Bouerer, the First Earl of Holderness, in order to defend against Viking raids.
In the 13th century, William de Froz II, Lord of Holderness rebelled against the king. As a result, in 1221 William de Froz II was excommunicated and Skipsea Castle was destroyed. Eventually, William de Froz II reconciled with King Henry III in 1227. Skipsea Castle was returned to William de Froz II, but without any defences.

### Wressle Castle

Wressle Castle is a quadrangular castle located in Wressle. The castle was built c.1380 - 1390 by Sir Thomas Percy. The castle was garrisoned by Parliament during the English Civil War and was largely demolished by an act of Parliament in 1650 as a precaution against future use in any further conflict. A fire gutted the remaining south range of the castle in 1796.
