3.4 Teak Wood Details:
Teak is found in tropical areas of the world. Thailand, Burma and India are just three countries. Teak is a natural wood, ideal for outside furniture. It contains natural oils that protect it against wet and cold weather. It can also be treated with teak oil giving it more protection against the elements. Teak is expensive although the growth of sustainable teak plantations means that the price will eventually fall and it will be more widely available.

Comparison Between Rust and Vreugd and One and Only Cape Town

...PART 1- Essay Rust and Vreugd can be seen as a suburban house in the city centre of Cape Town. This is unusual as homes in the city centre today are found to be apartments, lofts, condos and penthouses. It is rare to find a suburban-style house in the city centre, built in the past 20 years. From this it can be said that a penthouse is the development of the suburban house in the city centre. Many factors lead to this development and change of “city houses”. It is essential to first look at the characteristics of a suburban house and a penthouse to see what the differences are between these two homes, including references to the examples. Rust and Vreugd is an old house in the City of Cape Town built in 1771.(fig 1.1) It is a great example of VOC architecture and is a monument and museum open to the public today. Done by architect Anton Anreith, it includes characteristics of the Cape Dutch style. It is symmetrical, has a stoep, voorkamer and achterkamer but has some features only found later in Cape Town. It is evident that towards the end of the 18th century the flat roofed type of house was generally employed in the town, whilst the thatched and gabled roof was commonly used in the suburban and country houses. The town houses were mostly two storeys while those in the country were one storey. It was designed on a grand scale and is larger than the average townhouse of its time. Its most distinctive features includes a highly ornamented classical façade, a stoep with...

...Complex Systems in Education CSE ESSAYS COURSE Complex Course on Writing English and American Essays for Advanced Students English Language Programs Division Bureau of Educational and Cultural Affairs Writing 2 United States Information Agency, Washington, D. C. 1999 2 3 How to Use this Complex Course Частные уроки Английского Языка 387-1231 MIND Speaks to MIND – Selected American Essays 4 Preface Some years ago, a visitor to our office, a professor of English at a large foreign university, asked if the English Language Programs Division had published a book of American essays for foreign students – especially students at the advanced level. Having to respond in the negative, I was, nonetheless, “intrigued” by the idea of a collection of essays that would form a source of stimulating ideas or thoughts that could be thoroughly examined in the EFL classroom, discussed and debated in free conversation, and perhaps, ultimately, lead to a significant growth in the exchange of information between cultures – via the printed page. From this rationale, then, there issues an explanation for the title, Mind Speaks to Mind, which itself is an “exchange of information” between the editor and Edward Hoagland in his essay, “On Essays”! And, readers are encouraged to study this essay first as a type of guideline concerning the nature/purpose of the essay. It is found on page 26. For ease of reference, the essays are presented in alphabetical order according...
