Book Description
This book focuses on the structural design of Interlocking Concrete Block Pavement (ICBP) including application, analysis, design, construction, and the fundamental design concept of ICBP backed by case studies to demonstrate long- term performance of ICBP. It helps to draw conclusions regarding the various geometric properties that must be applied to achieve the performance of ICBP. Features: Promotes the use of ICBP in the construction of pavements. Provides a comprehensive overview of concrete block paving. Discusses specifications from codes like ASCE 58- 16, ASTM, BS and IRC codes and datasets online. Includes chapters on choosing the materials and designing the type and the shape of the concrete block and the thickness of all layers of the pavement. Lists appropriate stipulated values for the various geometric properties. Aids in understanding the history and comprehensive application of ICBP. This book is aimed at graduate students and researchers in pavement and civil engineering.

Book Description
The 1982 statistics on the use of family planning and infertility services presented in this report are preliminary results from Cycle III of the National Survey of Family Growth (NSFG), conducted by the National Center for Health Statistics. Data were collected through personal interviews with a multistage area probability sample of 7969 women aged 15-44. A detailed series of questions was asked to obtain relatively complete estimates of the extent and type of family planning services received. Statistics on family planning services are limited to women who were able to conceive 3 years before the interview date. Overall, 79% of currently mrried nonsterile women reported using some type of family planning service during the previous 3 years. There were no statistically significant differences between white (79%), black (75%) or Hispanic (77%) wives, or between the 2 income groups. The 1982 survey questions were more comprehensive than those of earlier cycles of the survey. The annual rate of visits for family planning services in 1982 was 1077 visits /1000 women. Teenagers had the highest annual visit rate (1581/1000) of any age group for all sources of family planning services combined. Visit rates declined sharply with age from 1447 at ages 15-24 to 479 at ages 35-44. Similar declines with age also were found in the visit rates for white and black women separately. Nevertheless, the annual visit rate for black women (1334/1000) was significantly higher than that for white women (1033). The highest overall visit rate was for black women 15-19 years of age (1867/1000). Nearly 2/3 of all family planning visits were to private medical sources. Teenagers of all races had higher family planning service visit rates to clinics than to private medical sources, as did black women age 15-24. White women age 20 and older had higher visit rates to private medical services than to clinics. Never married women had higher visit rates to clinics than currently or formerly married women. Data were also collected in 1982 on use of medical services for infertility by women who had difficulty in conceiving or carrying a pregnancy to term. About 1 million ever married women had 1 or more infertility visits in the 12 months before the interview. During the 3 years before interview, about 1.9 million women had infertility visits. For all ever married women, as well as for white and black women separately, infertility services were more likely to be secured from private medical sources than from clinics. The survey design, reliability of the estimates and the terms used are explained in the technical notes.

Book Description
There is no alternative to concrete as a volume construction material for infrastructure. This raises important questions about how concrete should be optmised for short and long-term cost effectiveness, whilst allowing flexibility for radical innovations and developments. Concrete for Infrastructure and Utilties forms the Proceedings of the three day International Conference held during the Congress, Concrete in the Service of Mankind. 24-28 June 1996, organised by the Concrete Technology Unit, University of Dundee. It brings together the experience and technology of those involved in key infrastructure and utility construction. Topics discussed include the use of concrete structures in flood and coastal protection and in important transportation infrastructure such as bridges, roads, tunnels and airports. Also discussed is the use of concrete in the fields of oil and gas exploration, nuclear containment and in the construction of facilities to exploit alternative sources of energy, such as wind and water power.

Book Description
Concrete will be the key material for Mankind to create the built environment of the next millennium. The requirements of this infrastructure will be both demanding, in terms of technical performance and economy, and yet be greatly varied, from architectural masterpieces to the simplest of utilities.Radical design and concrete practices forms the Proceedings of the one day International seminar held during the Congress, Creating with concrete, 6-10 September 1999, organised by the Concrete technology unit, University of Dundee.
