Abstract: The seismic design of the moment-resistant plastic frames is aimed at forcing the structure to respond to the strong action of the weak beam, in which plastic loops are expected to form into beams on the faces of the columns. The regions of the khang are described in detail in such a way that the output of longitudinal steel bars allows to dissipate the energy of the earthquake. If SE SMA is used as a reinforcement instead of steel in the right places of the hinges or in the basic insulation, it will not only be able to dissipate adequate seismic energy, but also restore its original shape after the seismic event. Due to the higher cost compared to the cost of other building materials, SMA longitudinal ribs can be used together with steel ribs in the articulated areas of the beams. Such BCJs can allow design engineers to design connections that show minor damage and mitigate joint repairs after an earthquake. Keywords: Seismic, base isolation, SMA, beam, column & joints

The Council of Constance, like any other serious event involving many people and lasting over a considerable period of time, can be studied from many points of view. It started out as a gathering for purely ecclesiastical purposes. But some twenty or thirty thousand persons from every class of society, except, perhaps, the lowest, cannot come and remain together for almost four years to discuss one set of difficult and complicated questions without, intentionally or unintentionally, raising many other questions, social, religious, philosophic, economic and political, and forming for the moment, as it were, a microcosm of the forces of the age. Most of the issues that agitated Europe five hundred years ago cropped up sooner or later at Constance, the cost of living, the obnoxiousness of robber barons and private warfare, the right and wrong of tyrannicide, the conflict between Germans and Poles in the East and between English and French in the West, to say nothing of the special issues with which the Council was expected to deal, the claims of three popes to be the only true successors of St. Peter, the perilous teachings of Wiclef and Hus and the worldliness and corruption of church administration.

British involvement in whaling lasted for three and a half centuries. It began with the expansion of Europe, when the whale was located in Arctic waters, and ended only when the virtual extinction of the whale made the trade unprofitable. Those in the last stages of the trade argued, when conscience pricked, that the extermination of the whale was impossible because the cost/yield ratio would prevent the catching of "too many" of the last specimens. It proved, in the event, to be a false argument based, perhaps, on too optimistic a view of human nature, or perhaps on a misunderstanding of the economics of whaling. When Europeans could no longer make whaling pay there were still those - the Russians and Japanese - who worked on different principles, and between them the various whaling nations have brought stocks so low that there are serious doubts if they can ever revive. With such mobile migratory marine animals there has to be a fairly large number before effective breeding can take place and nobody at the moment knows if the surviving specimens can provide for the future. Certainly the Right whale which has been protected throughout the modern phase of whaling has shown no appreciable increase in numbers. The abundance of food may encourage a revival of the blue and fin whales, but it has not yet done so, and scientists are pessimistic. One thing is absolutely clear: whatever happens to the survival of the whales, there can be no whaling in the foreseeable future among the baleen whales. Any attempt to revive the free-for-all slaughter would simply return the species involved to the threshold of extinction....


Concrete Mix design is the process of finding the right proportions of cement, fine aggregate, coarse aggregate ,water and admixtures to achieve strength and durability requirements .The procedure for designing concrete mixes for general types of construction are recommended in IS 10262:2009.This code is based on the experiments carried out at the national council for cement and building materials, New Delhi. The method is mainly based on the basic assumption that the compressive strength of concrete is governed generally by the water cement ratio. This study investigates the effect of other parameters also on the mix design and the cost of concrete.

The possibility of the use of a layer of natural material under foundations for seismic base isolation was investigated. The dissipation of seismic energy of a low-cost natural material with adequate thickness, bearing capacity, and lateral and vertical stiffness, which can serve as an optimal solution for seismic base isolation under the foundations of many structures, was tested. This paper presents the results of a brief experimental study to determine the effectiveness of ordinary limestone sand under the foundation of a cantilever concrete column to increase its seismic resistance. The behavior of small-scale columns with three substrates below the foundation (rigid base, the thin layer of limestone sand, and the thick layer of limestone sand) was investigated by the shake table. The column was exposed to a set of horizontal base accelerations until structure collapse. It was concluded that a layer of limestone sand of appropriate thickness and compressibility can serve as the means a seismic base isolation. The nonlinear numerical model for the dynamic analysis of planar concrete structures coupled with soil is briefly presented and verified by the performed experimental tests.

This study aims to find a comparison of the calculation of the cost of goods manufactured in the CV. Mitra Setia Blitar uses the company's method and uses the Job Order Costing (JOC) method. The method used in this study is quantitative. The types of data used are quantitative and qualitative. Quantitative data is in the form of map production cost data while qualitative data is in the form of information about map production process. The result of calculating the cost of production of the map between the two methods results in a difference of Rp. 306. Calculation using the company method is more expensive than using the Job Order Costing method. Calculation of cost of goods manufactured using the company method is Rp. 2,205,000, - or Rp. 2,205, - each unit. While using the Job Order Costing (JOC) method is Rp. 1,899,000, - or Rp 1,899, - each unit. So that the right method used in calculating the cost of production is the Job Order Costing (JOC) method

Abstract As they say, money can’t buy happiness. However, the lack of it can make people’s lives much harder. From the moment we open our first bank account, we have to make lots of financial decisions in our life. Should I save some money or should I spend it? Is it a good idea to ask for a loan? How to invest my money? When we make such decisions, unfortunately we sometimes make mistakes, too. In this study, we selected seven common decision making biases - anchoring and adjustment, overconfidence, high optimism, the law of small numbers, framing effect, disposition effect and gambler’s fallacy – and tested them on the Hungarian population via an online survey. In the focus of our study was the question whether the presence of economic knowledge helps people make better decisions? The decision making biases found in literature mostly appeared in the sample as well. It proves that people do apply them when making decisions and in certain cases this could result in serious and costly errors. That’s why it would be absolutely important for people to learn about them, thus increasing their awareness and attention when making decisions. Furthermore, in our research we did find some connection between decisions and the knowledge of economics, people with some knowledge of economics opted for the better solution in bigger proportion

Justice that has not existed and is apparent among the disabilities in Indonesia is very large and spread in the archipelago is very large, making the issue of equality is a very important thing especially with the publication of the Disability Act No. 8 of 2016 at the beginning of that year. Only a few provinces that understand properly and well on open and potential issues and issues will affect other areas including the increasingly growing number of elderly people in Indonesia due to the increasing welfare of the people. The government of DKI Jakarta, including the most concerned with disability, from the beginning has set a bold step to defend things related to disability, including local governments in Solo, Bali, Makassar and several other areas. Leprosy belonging to the disability community has a very tough marginalization, the disability that arises from leprosy quite a lot, reaches ten percent more and covers the poor areas of Indonesia, such as Nusa Tenggara Timur, Papua, South Sulawesi Provinces and even East Java and West Java and Central Java Provinces. If we compare again with the ASEAN countries we also do not miss the moment in ratifying the CRPD (Convention of Rights for People with Disability) into the Law of Disability No. 8 of 2016 which, although already published but still get rejections in some sections because do not provide proper empowerment and rights equality. The struggle is long and must be continued to build equal rights in all areas, not only health and welfare but also in the right of the right to receive continuous inclusive education.

Payday loans are small-amount, short-term, unsecured, high-cost credit contracts provided by non-mainstream credit providers. Payday loans are usually taken out to help the consumer pay for essential items, such as food, rent, electricity, petrol, broken-down appliances or car registration or repairs. These consumers take out payday loans because they cannot — or believe that they cannot — obtain a loan from a mainstream credit provider such as a bank. In recent years there has been a protracted debate in Australia — and in several overseas jurisdictions — about how to regulate the industry. Recent amendments to the National Consumer Credit Protection Act 2009 (Cth) — referred to in this article as the 2013 reforms — are designed to better protect payday loan consumers. While the 2013 reforms provide substantially improved protection for payday loan consumers, further changes to the law may be warranted. This article raises several law reform issues which should be considered as part of the 2015 review into small amount credit contracts, including whether the caps on the cost of credit are set at the right level, whether the required content and presentation of the consumer warnings needs to be altered, whether more needs to be done to protect consumers who are particularly disadvantaged or vulnerable and whether a general anti-avoidance provision should be included in the credit legislation.

When repairing and replacing electrical wiring in enterprises, the main difficulty is the lack or poor quality of documentation, plans for conductors laying. Distinguishing wires (cables) and their cores by the color of the shells or using tags attached to the ends is difficult if the shells have the same color and there are no tags. Devices and technical solutions used to identify wires and cables do not allow recognizing conductors without breaking the electrical circuit, removing insulation, and de-energizing the network. Searching for the right conductor is a time-consuming operation. (Research purpose) The research purpose is developing a new microcontroller device for identifying wires using an acoustic signal. (Materials and methods) Literature sources has been searched for devices for conductors identifying. (Results and discussion) The article proposes a method that involves feeding an acoustic signal to a wire at one point and capturing it at another, in order to recognize the desired wire. The article presents results of comparison of the developed microcontroller device for identifying conductors using an acoustic signal with known devices and methods for conductors recognizing. (Conclusions) The article reveals the shortcomings of existing methods and means of identifying wires and cables. Authors performed a theoretical calculation of the sound pressure in the conductor at a given distance. The article presents the calculation of speed of acoustic waves in conductors with different types of insulation. Authors designed a microcontroller device for identifying conductors using an acoustic signal and tested it. It was determined that the device increases the safety of work, reduces the cost of operating internal wiring and identification time; eliminates the violation of wire insulation, the need to disable electrical receivers. The convergence of theoretical calculations and experimental data was shown.
