Let G=(V,E) be a simple graph. A subset S of V(G) is called a strong (weak) efficient dominating set of G if for every v∈V(G),|N_s [v]∩S|=1.(|N_w [v]∩S|=1) , where N_s [v]={u∈V(G) ∶uv ∈E(G),deg〖u ≥degv 〗 }. (N_w [v]={u∈V(G) ∶uv ∈E(G), degv ≥degu The minimum cardinality of a strong (weak) efficient dominating set of G is called the strong (weak) efficient dominating set of G and is denoted by γ_se (G) (γ_we (G)). A graph G is strong efficient if there exists a strong efficient dominating set of G. The strong efficient bondage number b_se (G) of a non empty graph G is the minimum cardinality among all sets of edges X⊆E such that γ_se (G-X)>γ_se (G). In this paper, the strong efficient bondage number of some path related graphs and some special graphs are studied.

(|N_w [v]∩ S|=1), where N_s (v) = {u ∈V(G) : uv∈ E(G), deg u ≥ deg v}. (N_w (v) = {u ∈V(G) : uv∈ E(G), deg v ≥ deg u}). The minimum cardinality of a strong (weak) efficient dominating set of G is called the strong (weak) efficient domination number of G and is denoted by γ_se(G) (γ_we(G)). A graph G is strong efficient if there exists a strong efficient dominating set of G. The strong efficient co-bondage number 〖bc〗_se(G) is the maximum cardinality of all sets of edges X ⊆ E such that γ_se (G+X) γ_se(G). In this paper, the strong efficient co-bondage number of some standard graphs and some special graphs are determined.

Opis:
A dominating set S of a graph G is called efficient if |N[v]∩ S| = 1 for every vertex v ∈ V(G). That is, a dominating set S is efficient if and only if every vertex is dominated exactly once. In this paper, we investigate efficient multiple domination. There are several types of multiple domination defined in the literature: k-tuple domination, {k}-domination, and k-domination. We investigate efficient versions of the first two as well as a new type of multiple domination.

Opis:
Structure is an essential element of most architecture works, but beyond its main function to carry loads, it can also enrich and animate the architectural space. The architect, in cooperation with the engineer, may expand awareness of the architectural potential of the load-bearing system and design efficient structural forms that are based on the natural flow of forces and are simultaneously functional, unique, and aesthetic. The article shows how to design such forms and attempts to demonstrate that they can have a positive impact on the originality and beauty of an architectural object.

Opis:
Wireless sensor network is a significant piece of wireless communication. It is a gathering of an enormous number of sensor nodes that are set in remote spots. The sensors have ability to do a typical undertaking. So energy exhaustion plays a significant job in keeping up a stable network. To build the system lifetime, a different energy effective algorithm is required which expands the network lifetime and makes the network more energy productive. For the augmenting, the lifetime of the network diverse routing technique has been utilized which help in expanding the lifetime of the network. This article portrays the diverse routing protocol which helps in energy efficient routing in a wireless sensor network.

Opis:
The development of energy efficient buildings has been on the increase in recent years. This trend in architectural engineering reflects both the binding legal regulation and the rational approach of investors to the construction or refurbishment of buildings. When planning such an investment, it is necessary to scrutinize the underlying guidelines and the conditions in which the building will be developed, as well as its future useful life. Economic analysis of the effectiveness of investments in the building sector employs simple and discounted methods. Depending on the scope and complexity of envisaged construction work, it is possible to apply methods from both groups. However, simple methods should suffice for simple building projects, an example of which will be discussed in the article. Three variants of planned additional thermal insulation of external walls of a residential building will be presented. The results of our calculations showed that the payback period for such an investment would be too long, which is why it is recommended to combine the thermal insulation of outer walls with some broader measures so as to shorten the time needed to achieve a good return on investment ratio.

Opis:
The way compatible pairs of nitrate non-utilizing mutants (nit) are selected is usually not explained and remains unclear whether these pairs are representative for an isolate or strain. In addition, tester strains of Verticillium dahliae vegetative compatibility groups (VCGs) cross-react with at least one pair of tester strains of another VCG, and although it is a common knowledge of scientists working with the fungus that reversion of nit mutants to wild type occurs far too often, this fact is rarely mentioned in papers. To overcome the above problems, a protocol was developed for the generation of large number of nit mutants from any given isolate and to ensure that compatible pairs of mutants are indeed stable and the most frequent within the putative tester mutants produced from each isolate. Thus, we provide a reproducible and objective way of selecting V. dahliae tester strains for each isolate and VCG. Although VC grouping is based on the formation of stable heterokaryons, we demonstrate in this work that cross-reactions cannot be eliminated and that strict genetic barriers between two main VCG groups are absent in V. dahliae.

Opis:
The aim of this paper is to introduce energy-saving civil engineering, to demonstrate the need for energy conservation, and to radically change the principles of building. The paper then shows the importance of the principle of sustainable development and acquaints the reader with the objectives of the European Union and its basic documents concerning measures to improve energy and climate protection standards in buildings. This paper presents the research programs and standards for the certification of buildings and housing estates inscribed in the principle of energy efficient civil engineering and sustainable development. Examples of low energy buildings from Germany and Austria are shown, with an emphasis on the principles of designing passive buildings. A vision of the future of architecture and civil engineering is presented using examples of innovative buildings and settlement structures designed based on energy saving and energy management.

Opis:
In the article, cradle to cradle approach, as the desired direction of changes in the management of resources in production processes, is discussed. The study based on the analysis of literature, action programs, and case studies. Attention has been focused on the development of cradle to cradle approach around the world. The research aimed to raise awareness of the importance of resource management so that waste generation would be eliminated from the manufacturing processes. Residues of consumption and production should be re-integrated into biological or technological circulation. Cradle to cradle approach means a revolutionary change in the approach to the organization of following processes: products and services design, production and distribution. It also extends the scope of responsibility of manufacturers and users, but at the same time gives a chance to reduce the negative impact on the environment and to create new job opportunities.
