ADAPTATION OF FLATS IN CONCRETE SLAB BUILDINGS FOR PEOPLE WITH DISABILITIES. ISSUES, COSTS, REIMBURSEMENT OPTIONS, COMPARISONS

Małgorzata BARTNICKA

Abstract Poland is bound by law to ensure equal opportunities and non-discrimination. Architectural barriers in space can be considered a form of discrimination against disabled people. The purpose of the article is to argue that both the old pre-cast concrete slab apartments as well as the newer buildings (built after 1995) require adaptation in order to cater for the needs of the disabled. The article outlines the developments in design for people with disabilities, starting from the programme(..)

TRADITION AND INNOVATION IN SERBIAN 21ST CENTURY ARCHITECTURE – TRADITIONAL MATERIALS, MODERN FORMS AND SUGGESTED DESIGNS

Predrag MILOŚEVIĆ/ Vladimir MILOŚEVIĆ/ Grigor MILOŚEVIĆ

Abstract It would seem that the need to preserve traditional building heritage is slowly gaining importance in modern day Serbia. As well as the need to develop modern house types that resembles traditional ones. The old master builders, whilst building homes in local towns and villages not only left their mark on every building they created, but a mark of the times and conditions in which they lived and worked. Their ambitions were furthered by the wish of the inhabitants of the future house, w(..)

IT TECHNOLOGIES IN ARCHITECTURE AND SPACE REPRESENTATION. BRUNO ZEVI METHODS REVISED

Aleksandra ŚLIWA

Abstract Space representation methods as described by Bruno Zevi in “Architecture as space” are still valid today. Projections, elevations, models, photos and films are commonly used and all of them define the space in a specific way, yet none defines it completely. The development of IT technologies caused emergence of new methods which shape the picture of today’s architecture. Originally, a conventional technical drawing was adapted to the computer environment, but it was the 3D technology th(..)

ENERGY PERFORMANCE ASSESSMENT OF ENVELOPES FROM ORGANIC MATERIALS

Yuriy BIKS/ Georgiy RATUSHNYAK/ Olga RATUSHNYAK

Abstract The paper estimates the thermal perfomance of effective building envelopes from organic materials for the construction of low-rise buildings. The popular types of walls made of natural energy-efficient materials with low carbon footprint are considered in numerical assessment: hempcrete, adobe, strawbale panel, earthbag and cordwood. The influence of the constructive layer type of the envelope on the amount of thermal inertia time is analyzed. It is revealed that the hempcrete wall has (..)

INFLUENCE OF SELECTED MICRO ADDITIVES CONTENT ON THERMAL PROPERTIES OF GYPSUM

Justyna CIEMNICKA/ Roman JASKULSKI/ Wojciech KUBISSA/ Karol PRAŁAT

Abstract The presented work focuses on the influence of the micromaterials (microspheres, aerogel and polymer hydroxyethyl methyl cellulose) on thermal properties of gypsum. The polymer and the aerogel are used as additives in the weight fraction, up to 1% of pure gypsum and the microspheres in the weight fraction, up to 10% of gypsum. The water-to-gypsum ratio was at the level of 0.75. Non-stationary method and Isomet 2114 experimental setup were applied for the purpose of measurements of therm(..)

NUMERICAL ANALYSIS OF THE RESPONSE OF PILE-RAFT SYSTEMS CONSIDERING THE APPLICATION OF CEMENT AND POLYPROPYLENE FIBER TREATMENT

Ali HASANZADEH

Abstract Long-term performance of civil engineering projects mainly depends on the strength of underground layers. When the underground soil layers are problematic or have low bearing capacity and strength against the applied loads, application of soil stabilization methods can be effective. In this study, performance of pile-raft systems using stabilized/reinforced soil under foundation is investigated. For validation, the obtained numerical results were compared with the existing results from (..)

TECHNICAL CONDITIONS OF THE UNIQUE STRUCTURE OF INVERTED SIPHON – HISTORY & PRESENT

Jacek HULIMKA/ Marta KAŁUŻA

Abstract An inverted siphon is sometimes used to enable a watercourse to pass under an obstacle. Such solution is usually applied for irrigation and sewage canals, but it is rarely observed in the case of rivers. There are two such passages in Poland the bigger one is the Klodnica River siphon under the Gliwice Canal, commissioned in 1936. The first part of the paper presents the history of the Gliwice Canal and, simultaneously, of the Klodnica River siphon. The further part describes the struct(..)

EVALUATION OF TIME DEPENDENT PRESTRESS LOSSES IN PRETENSIONED CONCRETE MEMBER WITH TOP AND BOTTOM TENDONS

Vadzim PARKHATS/ Rafał KRZYWOŃ

Abstract Prestress losses are usually calculated by bringing the tendons in the cross-section to the single resultant tendon. This solution is correct only for tendons concentrated in one part of the cross-section, while with their wider distribution, for example after the use of upper tendons, it may result in underestimation of losses in the lower tendons and overestimation in the upper tendons. The paper presents formulae to determine time dependent prestress losses separately for the top and(..)

VARIOUS PRESENTATION OF NOISE PERCEPTION IN BYDGOSZCZ GREEN AREAS

Małgorzata SZTUBECKA/ Marta SKIBA/ Maria MRÓWCZYŃSKA/ Anna BAZAN-KRZYWOSZAŃSKA

Abstract Sustainable management of the city’s space becomes vital due to the increasing environmental pollution. Organized urban space is treated as all resources that directly benefit local residents. Proper location and shape have an impact on the comfort of people’s rest. Urban noise pollution is gradually increasing, mainly due to rapid industrialization and urbanization. This paper addresses the issue of the interrelationships between the multitude of sounds that occur in selected areas of (..)

A CONCEPT OF THE GASIFICATION PLANT FOR SELECTED ORGANIC WASTE

Monika CZOP

Abstract It is observed that in the world economy the consumption of the natural resources increases which results in the growth of a stream of municipal and industrial waste. Both of these phenomena belong to the most important civilization problems. One of the potential directions of the waste management should be the recovery of energy from the combustible fraction. One of the possibilities to convert energy from waste into usable power is gasification, i.e. transformation of the municipal wa(..)

THE USAGE OF ULTRASOUNDS TO DISINTEGRATE ESCHERICHIA COLI BACTERIA CONTAINED IN TREATED WASTEWATER

Eliza HAWRYLIK

Abstract Sewage and sewage sludge is a place of the occurrence of many microorganisms, including pathogenic and relatively pathogenic bacteria. They may reach other environments, e.g. receiver waters or soil, thus creating a biological threat. The aim of this paper was to study, in laboratory conditions, the effect of low-frequency ultrasound on the disintegration of Escherichia coli bacteria present in purified wastewater. E. coli bacilli and ultrapure water were used for the study. The samples(..)

APPLYING INTERNAL CIRCULATION ANAEROBIC REACTOR FOR WASTEWATER TREATMENT: A CASE STUDY IN SAIGON PAPER MILL WASTEWATER TREATMENT PLANT

Nhat-Ha TRAN/ Manh-Ha BUI

Abstract Internal Circulation reactor (IC reactor) is an anaerobic digestive system with the capability to treat high-load Chemical Oxygen Demand (COD) of industrial wastewater (e.g. brewery, potato starch, pulp and paper). IC reactor advantages include of the following: only small areas required, shock load resistance, produces more biogas and uses less energy compared to the Upflow Anaerobic Sludge Blanket (UASB) reactor. BIOPAQ@ICX is an upgrade to BIOPAQ@IC that has higher efficiency, lower (..)

PHYSICOCHEMICAL METHODS OF NITRATES REMOVAL FROM WASTEWATER

Maciej ŻOŁNIERCZYK/ Krzysztof BARBUSIŃSKI

Abstract Nitrate(V) ions in surface water and sewage are pollutants, which excessive concentration have a negative impact on aquatic ecosystems. Due to the chemical properties, removal of nitrates from wastewater is a difficult process. In the municipal sector, biological denitrification (activated sludge) is the most commonly used process. However, in the case of industrial wastewater, where inhibiting substances or substances toxic to microorganisms are present in wastewater, it is necessary t(..)
