to design – проектировать, разрабатывать commissioning – пуск, ввод в действие maintenance – обслуживание, эксплуатация stage – ступень, этап, шаг

disposal – размещение, расположение endeavours – избавление, устранение averting – предотвращение, предупреждение contamination – загрязнение, порча hazardous – опасный, рискованный assessments – отчисления

to save – спасать, сохранять to destroy – разрушать

to investigate – разрабатывать, исследовать

2. Прочитайте и переведите текст. ENVIRONMENTAL ENGINEERING

It seems that engineering and ecology have nothing in common; however, nowadays people understand that all modern technologies should be “ecologised”. That is, a future specialist (an engineer-ecologist) will take part in the building process on its every stage (pre-designing, designing, commissioning and maintenance of the constructed object).

Environmental Engineering is the development of processes and infrastructure for the supply of water, the disposal of waste and the control of pollution of all kinds. These endeavours protect public health by preventing disease transmission, and they preserve the quality of the environment by averting the contamination and degradation of air, water, and land resources.

Environmental engineering is a field of broad scope that is connected with such disciplines as chemistry, ecology, geology, hydraulics, hydrology, microbiology, economics, and mathematics. It was traditionally a specialized field within civil engineering and was called sanitary engineering until the mid1960s, when the more accurate name environmental engineering was adopted.

Projects in environmental engineering involve the treatment and distribution of drinking water; the collection, treatment, and disposal of wastewater; the control of air and noise pollution; the management of municipal solid waste and

51

of hazardous waste; the cleanup of hazardous-waste sites; and the preparation of environmental assessments, audits, and impact studies.

The main task of highway and bridge construction is to save but not to destroy clean lakes and rivers. The whole world and particularly our country need specialists in this sphere. That’s why the qualification “Environmental Engineering” was created at the Highway Engineering faculty in 2001. The students study such specialized subjects as ecological law, monitoring and expertise.

Northern areas of the Omsk region are being investigated now. It is necessary to build roads and bridges there paying attention to wildlife and using environmentally friendly technologies. So, the need in such specialists as engineer-ecologists is constantly growing.

ECOSYSTEMS: WHAT THEY ARE

1. There are two "sides" in every ecosystem, the organisms on one hand and the environmental factors on the other. All the organisms – plants,

52

animals, and microbes – in the ecosystem are referred to as the biota (bio, "life"). The way the categories of organisms fit together is referred to as the biotic structure. The nonliving chemical and physical factors of

the

environment

(climate,

soil

quality

and

so

forth)

are

referred to as abiotic (a, "non") factors.

 

 

 

 

 

 

2. As it was noted before, the environment involves the interplay of many

physical and chemical, or abiotic

factors,

the

major

ones

being

rainfall (amount and

distribution over

the year), temperature (extremes

of heat and cold as well as average), light, water, wind, chemical nutrients, pH (acidity), salinity (saltiness) and fire. The degree to which each is present or absent, high or low, profoundly affects the ability of organisms to survive. However, different species may be affected differently by each factor. This difference in response to environmental factors determines which species may or may not occupy a given region.

3.In any study of the abiotic side of ecology, the key observation is that different species thrive under different conditions. This principle applies to all living things, both plants and animals. Some like it very wet; others like it relatively dry. Some like it very warm; others do best in cooler situations. Some tolerate freezing, others don't. Some require bright sun; others do best in shade. Thus, a single factor – temperature, say – can be varied in a systematic way, while all other factors are kept constant. Experiments show that, as temperature is raised from a low point that fails to support growth, plants grow increasingly well until they reach some maximum. Then, as temperature is raised still further, the plants become increasingly stressed; they do less well, suffer injury and die.

4.Since the results just described apply to any and all abiotic factors, we

observe what

is

known

as the Law of Limiting

Factors:

Any

one factor being outside its

optimal range at any given

time

will

cause

stress and limit the growth

of an organism. The factor

that

is limiting

the growth is called

the limiting factor. It may be any factor

that

affects

the organism. The Law of

Limiting Factors includes the problem of

"too much" as

well

as the

problem of "too little". For

example,

plants

may be stressed or killed by overwatering or overfertilizing as well as by underwatering or underfertilizing, a common pitfall for amateur gardeners. The factor that is limiting may change from one time to another.

5. The Law of Limiting Factors was first presented by Justus von Liebig in 1840 in connection with his observations regarding the effects of chemical nutrients on plant growth. He observed that restricting any one of the many different nutrients at any given time had the same effect: it limited growth. Thus, this law is also called Liebig's Law of Minimums. Observations since Liebig's time, however, show that his law has much broader application. Beyond its application to all abiotic factors, it may be applied to biotic factors as well.

53

6.In summary, the biosphere consists of a great variety of environments, both aquatic and terrestrial. In each environment we find plants, animal, and microbial species that are adapted to all the abiotic factors and also to each other in various feeding and nonfeeding relationships. Such environment supports a more or less unique grouping of organisms interacting with each other and with the environment in a way that perpetuates or sustains the entire group. That is, each environment with the species it supports is an ecosystem. Every ecosystem is interconnected with others through ecotones and through some species that cross from one system to another. At the same time, each species and, as a result, each ecosystem, is kept within certain bounds by limiting factors. That is, the spread of each species is at some point limited by its not being able to tolerate particular conditions, compete with other species, or cross some physical barrier.

7.A major concern of many environmentalists is how altering any factor, abiotic or biotic, may upset these limits and have far-reaching consequences through a ripple effect. Recognizing that everything in the biosphere is interconnected leads to the conclusion that nothing can be changed without affecting everything else to a greater or lesser degree. Obviously, humans have changed and are continuing to change things on a very large scale. What will these changes bring? Many environmentalists, including a number of scientists, promote the idea that we may be on the verge of a sudden and catastrophic "collapse of the biosphere" in which most if not all life may perish. On the other hand, cornucopians, also including a number of scientists, point out that there is no solid evidence to support such a "doomsday scenario"; much less that it is imminent. Indeed, they argue that all our experience to date should lead to the quite opposite conclusion: Humans have already caused the extinction of thousands of species and made manifold changes over most of the earth, but we and the biosphere are still doing well. Therefore, they maintain that continuing development as we have been does not pose an environmental threat.

THE CIVIL ENGINEERING FACULTY

The students of this faculty are trained in six qualifications, among which are building and economical specialities. The former are Architectural Design, Industrial and Civil Engineering, Manufacturing of Building Structures. The latter are Municipal Construction Economy, Economy and Management of Construction and Real Estate Expertise. In fact, the faculty has already got the status of an institute.

The speciality of building engineer is the most universal and wide-spread. In order to be a competent specialist the students of the faculty study a number of specialized subjects: Building Materials, Geodesy, Geology, Soil Mechanics, Bases and Foundations, Theoretical Mechanics and Strength of Materials. The latter is one of the most important subjects, because it deals with different kinds of loads. A building engineer should take into account the loadings which influence the building; he should be able to calculate the computed and limited strength and stresses of a building. Here may be included: bearing, banding, rupture, compressive, flexural, frictional, shear, tensile, shrinkage, torsional and wrapping strength.

The students of the faculty study various structures and buildings, their parts and elements and also construction technology. The structures and buildings are usually built of concrete, steel and wood. A structure consists of a basement, walls, partitions, floors, ceilings and a roof. All this the students study by listening to courses of lectures, as well as having practice at construction sites, where they get practical experience. The students of the faculty also get acquainted with Architecture; they study the architectural styles and various architectural structures.

The construction of any building, house or office is connected with utilities, lightning, heating, ventilation, water supply and sewerage. Besides, the students of the faculty have lectures on Construction Physics which deals with acoustics, heat insulation and microclimate. A good building engineer should follow the appearance of new building materials and achievements of modern construction.

Specializations Municipal Construction Economy and Economy and Management in Construction have acquired more importance nowadays. They are connected with general concepts of economy and manufacturing, trade and service. Here the economists in the sphere of construction are trained. The qualifications deal with the management of the city economy, including the enterprises of utility service: bath-houses, restaurants, wash-houses and hairdressing saloons.

58

The graduates of the faculty work on designing civil, industrial, and public buildings, at construction technology of the buildings, they work as building engineers, architects and managers.
